Abstract
Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of traditional Chinese medicine, and particularly relates to a traditional Chinese medicine composition with the efficacy of treating children's cold and application thereof. BACKGROUND
[0002] Influenza (hereinafter referred to as influenza) is one of the major public health problems faced by human beings, which is caused by influenza virus. Since 1889, there have been 6 detailed records of influenza pandemics. In the past 10 years, China has successively experienced outbreaks of influenza A H1N1, influenza B, and human avian influenza H7N9. Influenza virus is prone to recombination and variation, and spreads rapidly. It can cause seasonal epidemics every year, and some cases can develop into severe influenza due to complications such as pneumonia. A small number of severe cases progress rapidly, and can die of acute respiratory distress syndrome (ARDS) and / or multiple organ failure. Children are susceptible and high-risk groups of influenza, and outbreaks and epidemics can occur in places where children gather, such as schools and nurseries.
[0003] China's 0-15-year-old children have reached 247 million, accounting for 17.80% of the total population. Respiratory diseases rank first in the disease spectrum of children. A survey of 3576 children aged 0-14 in more than 100 cities shows that the top three diseases are cold (74.7%), fever (59.8%), and cough (56.0%). Children's cold ranks first in pediatric respiratory diseases. Children can have 6-8 colds a year, and 10%-15% of children have up to 12 colds a year, making it the most common respiratory disease. Common cold-related pathogens include rhinovirus, coronavirus, respiratory syncytial virus, parainfluenza virus, adenovirus, enterovirus, etc. Viruses are mediated by cough and sneezing and spread through respiratory droplets. First, they adhere to the M cells in the lymphoid epithelial area of the adenoid, and then move to the posterior nose through the nasal mucosa cilia. Respiratory mucosal edema and congestion lead to exudation. The disease often occurs during seasonal transition, especially in winter and spring. The onset is relatively acute, with symptoms such as fever, nasal congestion, sore throat, cough, sneezing, and runny nose. It is estimated that 10%-15% of children need to see a doctor due to influenza infection every year. During the influenza season, more than 40% of preschool children and 30% of school-age children may be affected by influenza. Due to passive immunization protection from the mother, children under 6 months are less likely to be infected with the disease. The 6-month to 3-year-old age group is at high risk for influenza, and is prone to severe influenza and a high incidence of complications. Children and adolescents aged 5 to 20 are at high risk for influenza, and the incidence of influenza in this age group can reach about 50% during the pandemic, which is 1.5-3 times higher than that of adults. Generally, infected individuals can expel viruses 24-48 hours before the onset of clinical symptoms, and the amount of virus expelled significantly increases 0.5-1.0 days after infection, reaching a peak within 24 hours of onset. Children with influenza have sudden onset, fever, and body temperature up to 39-40℃, accompanied by chills, rigor, headache, general muscle soreness, fatigue, loss of appetite, often cough, sore throat, runny nose or nasal congestion, and a small number of cases of nausea, vomiting, and diarrhea. Children's digestive symptoms are more common than adults, and infant influenza is atypical. Neonatal influenza is rare, but influenza is prone to pneumonia. Acute laryngitis, acute otitis media, tracheitis, bronchitis, bronchiolitis, and pneumonia caused by influenza virus in children are more common than in adults. Most influenza patients without complications recover in 3-7 days, but cough and physical recovery often last 1-2 weeks. Adults and older children generally expel viruses for 5 days (3-8 days), and the duration of virus shedding varies depending on the strain of the virus. Young children expel the same amount of virus as adults when they get sick, but the duration of virus shedding is longer than that of adults. Compared with adults, long-term virus shedding is common in infant cases (1-3 weeks). Therefore, children are actually the most important source of influenza transmission and the cause of repeated or acute exacerbations of illness in children. Timely treatment of children with influenza is of great significance to the health of children and the reduction of additional medical costs.
[0004] There is no specific antiviral drug for common cold in western medicine. Commonly used drugs for children's cold include antiviral drugs such as neuraminidase inhibitors (Oseltamivir, Zanamivir), M2 ion channel blockers (Amantadine and Rimantadine), but there are many adverse reactions and viral drug resistance problems in clinical application. At present, the proportion of children's drug market and market demand in China is rising, and the sales of pediatric drugs in Chinese public medical institutions in 2019 reached 8.905 billion yuan, with a year-on-year growth of 11.61%. However, there are few special dosage forms and specifications of children's drugs, and the market urgently needs a safe and effective drug for children's cold.
[0005] Viral respiratory infection is an acute respiratory infection caused by various viruses, which is divided into viral upper respiratory tract infection and viral lower respiratory tract infection. The former is manifested as acute rhinitis, pharyngitis and laryngitis, and the latter is manifested as acute tracheitis, bronchitis and pneumonia. This kind of disease has a high incidence, is generally susceptible to the population, and is more susceptible to children, the elderly, malnutrition and chronic diseases. It is worth noting that after the spread of the 2019 novel coronavirus disease (Corona Virus Disease 2019, COVID-19), viral respiratory infection has become prevalent worldwide.
[0006] Due to immature immunity, children may be more susceptible to infectious viruses than adults, and infants and young children are particularly susceptible to respiratory infections. In children, the mortality and morbidity of respiratory infections are still higher than those of any other disease. At present, viral respiratory infection is a frequently-occurring disease in pediatric clinics, ranking first in the number of pediatric outpatient and inpatient cases, and seriously threatening the health of children. Only for influenza, about 870,000 children under the age of 5 are hospitalized worldwide each year.
[0007] In addition, the incidence of viral lower respiratory tract infection has shown an increasing trend in recent years. According to the etiological study, viral pneumonia accounts for about 18% of community-acquired pneumonia and about 5% of hospital-acquired infection in the same period, and it has attracted more and more attention. Therefore, how to quickly and effectively cure respiratory viral infectious diseases is particularly important. SUMMARY
[0008] Children's physiological characteristics are characterized by delicate internal organs and underdeveloped physical constitution. The fact that children's internal organs are "developed but not fully formed" and "fully formed but not robust" determines their pathological characteristics of being "easily deficient or excessive" and "easily susceptible to cold or heat." Children's "qi and blood are not yet regulated, their internal organs are fragile, and their pores are open and loose." Being immature, they do not know how to protect themselves and cannot tell whether they are cold or hot, relying entirely on the care of their families. "Although their spirit is still strong, their temperament is not yet settled. They do not choose their clothing carefully; or they indulge in dressing as they please, are spoiled and unpredictable, indulge in raw and cold foods, or overeat cold or hot foods." All of these can cause children's pores to open and close improperly, their defenses against external pathogens to be weak, and they are susceptible to colds. The common cold in children is initially caused by the invasion of wind evil. The initial site of the infection is in the skin and muscles of the body. Heat is a yang evil, which is scorching and flaring upward. When wind-heat causes illness, the child may have a high fever, mild chills, and sweating or little sweating. When the heat evil disturbs the clear orifices, headache will occur. When wind-heat obstructs the throat and damages body fluids, redness, swelling and pain in the throat and dry mouth will occur. In clinical practice, headache, body aches and other head and face symptoms may be observed.
[0009] The lungs govern qi and respiration, and are responsible for the dispersing and descending of qi. They are externally connected to the skin and hair, and are responsible for protecting the body from external pathogens. The mouth, nose, skin, and hair are the channels through which external pathogens invade. When the lungs' defensive, protective, warming, and nourishing functions are normal, it is difficult for the six external pathogens to invade and harm the body. Children's skin is delicate and their defenses are thin, making it easy for pathogens to enter through the skin surface, thus easily damaging their lungs. When external wind-heat pathogens invade, the lungs are the first to be affected and become ill. Moreover, children's "lungs are often deficient," so the location of colds in children is in the "lungs."
[0010] Children are characterized by a "pure yang constitution," characterized by vigorous growth, rapid development, and abundant blood and qi. This internal and external heat easily transforms into internal heat, making them susceptible to external pathogenic factors that can manifest as internal heat. This can also occur when "heat in the heart and lungs is expelled by wind, thus allowing the wind to injure the skin and hair and enter the internal organs." The pathogenesis of wind-heat obstructing the lungs in children due to external pathogenic invasion stems from the combination of wind-heat pathogens and the child's pure yang constitution, resulting in internal heat accumulation and affecting both the lungs and the defensive qi.
[0011] The yang collaterals of the skin are where the lungs converge. The defensive qi relies on the lungs' qi-dispersing function to strengthen the skin surface and perform its protective function. If wind-heat attacks the surface, the yang collaterals become blocked, lung qi stagnates, and the defensive qi weakens. External pathogens like wind and heat can enter through the mouth, nose, or skin, causing lung qi to become congested and unable to circulate. Abnormal opening and closing of the airways leads to airway obstruction, and the turbid qi cannot escape. To expel the pathogens, the lung qi rises and impacts the glottis, causing coughing. The nose is an empty orifice, directly connected to the outside world, making it highly susceptible to external pathogens. When wind-yang rises and attacks the head and face, wind-heat obstructs the clear orifices, causing nasal congestion. When the orifices lose their clarity, the struggle between the body's resistance and pathogens occurs, leading to frequent sneezing as the pathogens are expelled. When external pathogens enter through the nose, nasal discharge cannot be contained, resulting in runny nose. In addition, the lungs and large intestine are internally and externally related. Lung heat can easily cause constipation by descending to the large intestine through the meridians. Timely bowel movement can help the lung heat to be released through the anus, thus clearing the lungs and relieving heat.
[0012] In summary, pediatric cold is caused by the invasion of pathogenic wind-heat from the skin, hair, mouth and nose. In addition, children's mental awareness has not fully developed, and they are unable to regulate their cold and warmth on their own. Once they are affected by pathogenic factors, the disease occurs. The pathological location is in the lung. The invasion of pathogenic wind-heat causes disharmony of the defensive aspect, and combined with the yang-exuberant constitution of children which is prone to transformation into heat, it affects the qi movement of the lung collaterals, leading to stagnation of qi collaterals, failure of the lung qi to disperse, congestion of pathogenic heat in the lung, blockage of the airway, and simultaneous disease of the lung and the defensive aspect.
[0013] Pediatric cold is characterized by the external invasion of wind-heat, disharmony of the defensive aspect, congestion of pathogenic heat in the lung, and blockage of the airway as its etiology and pathogenesis. The inventor proposed the treatment principle of "clearing the sense of discomfort and relieving the exterior, dispersing the lung qi and clearing heat", using pungent-cool herbs to relieve the exterior and clear away pathogenic factors, and dispersing the lung qi and clearing heat to eliminate internal fire, so that pathogenic factors are removed, the fire is dissipated, the lung resumes its dispersing function, and the airway is unobstructed, then the symptoms of the lung and the defensive aspect will naturally disappear.
[0014] Following the principle of "the visceral qi of children is pure and sensitive, and can respond promptly to treatment", the medication for children should be gentle and flexible. The physiological and pathological characteristics of children are that on the one hand, their viscera are delicate, their form and qi are not fully developed, they are prone to illness, and the disease transmission is rapid; on the other hand, they have vigorous vitality, rapid development, pure and sensitive visceral qi, and are prone to recovery. Therefore, the medication for children needs to be gentle and flexible, and heavy or strong medications should not be used. Pediatric cold is mostly caused by the invasion of pathogenic wind-heat into the lung and the defensive aspect, with a short course of disease and relatively mild symptoms. Therefore, during treatment, the medication should achieve the desired effect as soon as possible, and "the regulation should be balanced, and the tonifying and purging should not exceed the appropriate dosage".
[0015] The pharmaceutical composition of the present invention is modified based on the experience of Lianhua Qingwen in the treatment of pediatric cold and influenza. Based on the fact that the pathological location of this disease is in the lung and the defensive aspect, following the principle of "for diseases in the upper part, induce vomiting to expel them", the medications used should be light in quality, thin in flavor, cool in nature, and have the function of dispersing and penetrating, so as to exert the effect of clearing and dispersing, helping the pathogenic heat to disperse from the exterior, and also conforming to the fact that the lung is located at the highest position and is extremely clear in nature. Flos Lonicerae and Fructus Forsythiae in Yinqiao Powder are selected to disperse wind-heat and clear away heat and toxins, and Mentha haplocalyx is selected to disperse wind-heat and soothe the throat. The effect of relieving the pathogenic heat in the lung in Mahuang Xingshi Gancao Decoction in Treatise on Febrile Diseases by Zhang Zhongjing in the Han Dynasty is adopted. In the original formula of Mahuang Xingshi Gancao Decoction, there is 4 liang of Ephedrae Herba and half a jin of Gypsum Fibrosum, and the ratio of the two is 1:2. In the pharmaceutical composition of the present invention, honey-fried Ephedrae Herba is mainly used to relieve cough by dispersing the lung qi, and sweating and relieving the exterior is secondary, so the ratio of Ephedrae Herba to Gypsum Fibrosum is 1:3 to prevent excessive relieving of the exterior, following the treatment principle of Liu Wansu for pediatric cold that "it is advisable to prevent problems before they occur, adopt the method of patrolling guards, use medications for nourishing nature, and preserve their true nature".
[0016] The disease is characterized by wind-heat attacking from outside, loss of defensive qi, heat blocking the lung, and airway obstruction. The treatment should consider the lung-wei and coordinate the lung-qi. The disease is characterized by the child's failure to resolve the exterior syndrome, and the interior treatment of heat steaming. The disease is given a cool and refreshing medicine to resolve the exterior syndrome, open the pores, and give the exterior evil a way out. The heat in the interior can be resolved, and the heat can be cooled. The honeysuckle and forsythia are used to disperse and penetrate the heat in the lung-meridian. The gypsum is used to cool and disperse, resolve the exterior, and reduce fever. The mint disperses wind-heat and clears the throat. The isatis root clears heat and detoxifies, and relieves the throat and swelling. The child's cold is rapidly transmitted, so it should be actively intervened. The wind-heat is resolved to the outside, and the heat in the interior is cleared. The exterior evil and the interior heat are both resolved. The lung and the large intestine are related, so the purgation is used in the exterior treatment. The purpose is to clear the lung and purgation, and to clear the lung and purgation. The spleen and stomach are weak, so the red sage is used to clear the lung, remove blood stasis, and regulate immunity. The agastache is used to dispel dampness.
[0017] The pharmaceutical composition of the present application is derived from Lianhuaqingwen, which is composed of 13 drugs, i.e., forsythia, honeysuckle, fried ephedra, fried bitter apricot kernel, gypsum, isatis root, maima guanzhou, fishy grass, broadleaf, rhubarb, red sage, menthol, and licorice. The pharmaceutical composition of the present application is based on Lianhuaqingwen, which is composed of 11 drugs, i.e., forsythia, honeysuckle, mint, honey ephedra, gypsum, fried bitter apricot kernel, isatis root, broadleaf, red sage, rhubarb, and licorice. The maima guanzhou and fishy grass are removed, and the honeysuckle is replaced by the mint.
[0018] Maima guanzhou was first recorded in Shennong Bencao Jing and listed as inferior drug. It is bitter and slightly cold in nature, and has small toxicity. It is related to liver and stomach meridians, and has the effects of clearing heat and resolving toxicity, and cooling blood and stopping bleeding. The main effects and clinical research of maima guanzhou in respiratory system diseases are concentrated in anti-influenza virus and antibacterial aspects. Many children have liver and kidney dysfunction or weak spleen and stomach, and children are prone to vomiting after taking drugs. Therefore, maima guanzhou is removed from the prescription considering the above factors.
[0019] Fishy grass is a drug for treating phlegm-heat blocking the lung and lung abscess with pus and blood. The child's cold is in the lung-wei, and has not reached the stage of phlegm-heat blocking the lung and thick sputum. Fishy grass has a fishy smell and is not easy to correct, which causes poor compliance of children. Considering the child's immature yin and yang, and weak spleen and stomach, maima guanzhou and fishy grass are removed, so that the heat-clearing and toxicity-resolving effect is slow, and the spleen and stomach are prevented from being damaged.
[0020] Both *Lonicera japonica* (mountain honeysuckle) and *Lonicera macrantha* (golden honeysuckle) are included in the 2020 edition of the *Chinese Pharmacopoeia*. Their properties and meridian tropism (sweet, cold; entering the lung, heart, and stomach meridians), functions and indications (clearing heat and detoxifying, dispersing wind-heat; used for carbuncles, boils, sore throat, erysipelas, dysentery due to heat toxins, wind-heat colds, and febrile diseases), and dosage (6-15g) are exactly the same. However, *Lonicera japonica* is actually *Lonicera macrantha*, which has been shown in experiments to have a certain therapeutic effect on the common cold caused by influenza viruses. Flavonoids extracted and isolated from *Lonicera macrantha* have varying degrees of inhibitory effects on different types of bacteria, including *Staphylococcus aureus*, *Streptococcus pneumoniae*, *Corynebacterium diphtheriae*, and *Pseudomonas aeruginosa*. It also has strong antibacterial effects against common pathogens and opportunistic pathogens causing respiratory infections. Considering the comprehensive antibacterial effect, we used *Lonicera japonica* instead of *Lonicera macrantha* to achieve a better antibacterial effect.
[0021] Menthol can cause adverse reactions in the digestive system, mainly manifested as a cold feeling and discomfort in the stomach. Considering that children have incomplete gastrointestinal function, menthol was modified into peppermint medicinal material, and peppermint oil was extracted for medicinal use.
[0022] In this formula, the principal herbs are Forsythia suspensa and Lonicera japonica. Forsythia suspensa is slightly cold in nature and bitter in taste, and enters the lung and heart meridians. It clears heat and detoxifies, and disperses wind-heat. It soothes the exterior of the body and clears internal heat. On the one hand, it is used for its ascending and dispersing power to penetrate heat to the exterior, and is combined with Ephedra sinica to disperse wind-heat in the lungs, following the principle of "releasing stagnant fire." On the other hand, it targets the internal heat caused by external pathogens, and is aided by Gypsum fibrosum and Isatis indigotica to clear heat and detoxify. Its pungent and cool nature makes it the principal herb. Lonicera japonica: sweet and cold in nature, and enters the lung, heart, and stomach meridians. It disperses wind-heat, clears heat and detoxifies, and is used for wind-heat colds and febrile diseases. This product is sweet and cold in nature, which can effectively disperse heat evil in the lung meridian and allow heat to reach the exterior. When combined with forsythia, it helps to clear the stagnant heat in the lungs. Forsythia and honeysuckle complement each other. Both have a fragrant aroma. Forsythia has a strong ability to clear internal heat and detoxify, while honeysuckle tends to disperse exterior heat. Moreover, it is sweet and cold in nature and does not harm the spleen and stomach. It can gently promote the exterior and disperse wind-heat. While dispersing the exterior evil in the defensive qi, it also takes into account the characteristic of external wind-heat evil qi accumulating and transforming into heat.
[0023] The ingredients are peppermint, honey-processed ephedra, and gypsum.
[0024] The adjuvant herb is stir-fried bitter almond, which is bitter and pungent in taste, warm in nature, and enters the lung and large intestine meridians. Its function is to drain and moisten, moisten the lungs and stop cough, making it an essential medicine for treating cough and asthma. When almond is combined with ephedra, it can disperse and descend, lower qi and moisten dryness, and restore its descending function. One disperses and the other descends, so the cough is relieved and calmed. The combination of the two herbs disperses and stops cough, improving cough and shortness of breath in children with colds.
[0025] Isatis root: Bitter in taste, cold in nature, and enters the heart and stomach meridians. Its functions include clearing heat and detoxifying, cooling the blood and relieving sore throat. It is often used for external pathogenic factors causing fever and sore throat. It also has the effects of clearing heat and detoxifying, cooling the blood and relieving sore throat in children with colds that easily accumulate heat and cause sore throat.
[0026] Pogostemonis Herba: bitter, nature, spleen and stomach lung. Function of aromatic wet, wake up the stomach to help the stomach. Its nature is not sharp, Xidan, mild wet and not dry, good at wet and turbidity, wake up the stomach, and stop vomiting, children with weak intestines and stomach, susceptible to external pathogens, not fragrant, easy to wet and wet, so with Pogostemonis Herba aromatic wet, open the stomach and spleen, play the effect of "wake up the stomach and spleen, and the evil spirit will be no room and cure."
[0027] Rhodiola: sweet, bitter, nature, lungs, spleen, heart. Has the effect of clearing the lung and regulating immunity, the use of Rhodiola in this party, on the one hand, children are young Yin and Yang body, the development of five internal organs and six viscera is not complete, weak resistance, so use Rhodiola to improve the body's immunity, on the other hand, with gypsum to clear the lung and remove blood stasis.
[0028] Rhubarb: bitter, cold, spleen, stomach, large intestine, liver, pericardium. Clearing the lung and purging the lung. Based on the lung and large intestine, use rhubarb to clear the lung and purging the lung, and the lung heat is clear, considering the children can not bear the law, so the amount of drug in the prescription is small, to stop the disease.
[0029] Make medicine:
[0030] Licorice: sweet, nature, heart, lung, spleen and stomach. Effect of spleen and qi, lung moistening and coughing, regulating various drugs. The drug is sweet and flat, combined with the earth, into the spleen and stomach with Pogostemonis Herba to benefit the spleen and stomach and harmonize the center, and bitter apricot kernel to moisten the lungs and stop coughing, and harmonize various drugs, so the prescription is the medicine.
[0031] In summary, the pharmaceutical composition of the present application is formed according to the pathogenesis characteristics of pediatric cold and the physiological characteristics of the tender organs and viscera of children. The composition of the classical prescription combines the external and internal heat, and does not forget to protect the healthy qi, and the spleen and stomach, which embodies the treatment principle of lung and spleen, and the treatment principle of lung and spleen. The treatment principle of lung and spleen, and the treatment principle of lung and spleen. The composition is derived from the classical, and is applied in the clinic, combined with the physiological characteristics of pediatric disease, and is verified by experimental research. The theory of disease - pathogenesis - treatment principle - prescription and drug, reason, method, prescription and drug, and reason, method, prescription and drug, are connected, and the prescription is reasonable. Remove the mianma guanzhong, fishy grass, replace the honeysuckle with the mountain honeysuckle, and replace the mint with the mint. In the case of reducing the medicine, it is more suitable for children to take, and the curative effect is equivalent to the lianhuaqingwen. It provides a better choice for the most lacking professional children medicine.
[0032] In view of the above technical problems existing in the present viral respiratory tract infection, especially children's cold, the present application provides a traditional Chinese medicine composition with the effect of treating children's cold and its application.

Before the test, the basal body temperature is measured once and recorded as T0, the basal body temperature is screened and grouped, the grouping is completed, and then the drug is administered, 30min after the administration, the rats are intraperitoneally injected with 20μg / kg LPS, and the anal temperature is measured every 1h after modeling and recorded as T xCalculate the body temperature difference ΔT over 5 consecutive hours, where ΔT = T x -T0.
[0170] 2.4 Anti-inflammatory experiment
[0171] KM mice, with equal numbers of males and females, were randomly divided into 6 groups according to body weight: the model group, the aspirin group, the Lianhua Qingwen group, the traditional Chinese medicine composition of this invention (LHQG) group, the comparative example 1 (LHQG-A) group, and the comparative example 2 (LHQG-B) group. The proposed clinical dose was 0.4 g crude drug / kg body weight, and the mouse dose was set at 4.0 g crude drug / kg, which was 10 times the proposed clinical dose; this was the clinically equivalent dose. The mice were administered the drug once daily for 3 consecutive days. Approximately 0.5 hours after the last administration, xylene was applied to the middle of the right ear, 15 μl on each side. The left ear was left untreated. Forty minutes later, the mice were euthanized by cervical dislocation. Ear flaps were punched out symmetrically from both ears, weighed using a precision analytical balance, and the weight was recorded. The degree of swelling and the swelling inhibition rate were calculated. The degree of swelling was calculated as: weight of the right ear flap - weight of the left ear flap. Swelling inhibition rate = (average swelling degree of model group - average swelling degree of drug treatment group) / average swelling degree of model group × 100%.
[0172] 3 Statistical Methods
[0173] Experimental data are expressed as mean ± standard deviation ( The significance levels were set at 0.05 and 0.01. Statistical analysis was performed using SPSS software. One-way ANOVA was used to compare means. First, a test for homogeneity of variance was performed. If the variances were homogeneous, the least significant difference (LSD) test was used. If the variances were not homogeneous, Dunnett's T3 test was used.

Specifically, the medicine can be an antipyretic, anti-inflammatory, cough-relieving and expectorant medicine.
[0189] Test Example 3
[0190] In order to clarify the analgesic effect of the traditional Chinese medicine composition of the present application, the granules prepared in Example 1 (hereinafter referred to as the traditional Chinese medicine composition (LHQG) of the present application) were used to perform the following efficacy tests.
[0191] 1. Test purpose
[0192] In this experiment, mice were induced to writhe by intraperitoneal injection of 0.7% acetic acid to observe the effect of the herbal composition of this invention on pain.
[0193] 2. Test Methods
[0194] 1) Dosage and grouping
[0195] Sixty KM mice were randomly divided into five groups according to their body weight, including the model group; the indomethacin group; and the high, medium, and low dose groups of LHQG, with dosages of 2.00, 1.00, and 0.50 g / kg, respectively. The dosage of indomethacin in mice was set at 5.00 mg / kg.
[0196] 2) Administration method
[0197] The drug was administered via gavage, following the same route of administration as in clinical practice. A disposable syringe was used, with a dosage of 10 ml / kg. Animals in the model group received the corresponding volume of solvent, and administration continued for 5 days.
[0198] 3) Observation indicators, time, and content
[0199] Newly received experimental animals were numbered, acclimatized for 5 days, and grouped as described above. All animals were fasted for at least 15 hours before the last administration. One hour after the last administration, 10 ml / kg of 0.7% acetic acid was injected into the peritoneal cavity of the mice to stimulate the visceral and parietal peritoneum, causing a deep, large-area, and prolonged pain response. This resulted in writhing behaviors in the mice, such as abdominal retraction, trunk and hind limb extension, and raised buttocks. The latency period of the writhing response and the number of writhing movements within 15 minutes were recorded as quantitative indicators of pain.
[0200] 4) Statistical methods
[0201] Experimental data were analyzed using SPSS 18.0 statistical software, with significance levels of 0.05 and 0.01. Results are expressed as mean ± standard deviation. The method involves first performing a normality test. For data that conforms to a normal distribution, one-way ANOVA is used to compare the means. If the variances are homogeneous, the least significant difference (LSD) method is used for pairwise comparisons. If the variances are not homogeneous, Dunnett's T3 test is used for pairwise comparisons. If the data does not conform to a normal distribution, nonparametric tests are used.
[0202] 3. Results
[0203] As shown in Table 5, compared with the model group, the number of writhing movements in the indomethacin group was significantly reduced (P<0.05), and the writhing latency in the LHQG medium-dose group was significantly prolonged (P<0.05), while the number of writhing movements was significantly reduced (P<0.05). The writhing latency in the indomethacin group and the LHQG high-dose group was slightly prolonged compared with the model group, but the difference was not significant (P>0.05). The number of writhing movements in the LHQG high- and low-dose groups was slightly reduced compared with the model group, but the difference was not significant (P>0.05).
[0204]
[0205] 4. Conclusion
[0206] Under the conditions of this experiment, LHQG significantly inhibited the pain response induced by acetic acid stimulation of the mouse peritoneum. This indicates that the herbal composition of this invention has analgesic effects and can be used in the preparation of analgesic drugs.

[0377] 5)Effects on CD4 + , CD8 + lymphocytes in lung tissue
[0378] As shown in Table 33 and Figure 9 , 10Shown in the figure, wherein, Figure 9 The effect of CD4 + , CD8 + cell fluorescence intensity value in lung tissue after 24h of exposure: CD4 + , CD8 + signal merge chart, A, normal control group; B, model control group; C, ribavirin tablet group; D, Lianhuaqingwen capsule group; E, LHQG low dose group; F, LHQG medium dose group; G, LHQG high dose group, Figure 10 The effect of CD4 + , CD8 + cell fluorescence intensity value in lung tissue after 2h of last administration: CD4 + , CD8 + signal merge chart, A, normal control group; B, model control group; C, ribavirin tablet group; D, Lianhuaqingwen capsule group; E, LHQG low dose group; F, LHQG medium dose group; G, LHQG high dose group.
[0379] Compared with the normal control group, CD4 + / CD8 + in the lung was significantly reduced (P ≤0.01) at 24h after exposure and 2h after last administration, indicating that the proportion of CD4 + , CD8 + in the lung was imbalanced in mice infected with respiratory syncytial virus. Compared with the model control group, CD4 + / CD8 + was significantly increased (P ≤0.05 or P ≤0.01) in the LHQG medium and high dose groups, ribavirin tablet group, and Lianhuaqingwen capsule group at 24h after exposure, and the LHQG low dose group showed an increasing trend, but there was no statistical difference. Compared with the model control group, CD4 + / CD8 + was significantly increased (P ≤0.01) in the LHQG low, medium, and high dose groups, ribavirin tablet group, and Lianhuaqingwen capsule group at 2h after last administration, indicating that oral administration of LHQG could inhibit the imbalance of CD4 + , CD8 + lymphocyte proportion in the lung of infected mice.
[0380]
[0381] The above test results show that LHQG can reduce the lung index, inhibit the replication of respiratory syncytial virus in the lung, reduce the accumulation of inflammatory factors in the lung, improve the pathological changes in the lung of the infected model mice, and LHQG can increase the CD4 + / CD8 +The ratio, inhibition of M1 polarization of macrophages, indicates that LHQG has the effect of regulating immune cells and maintaining immune balance. It is shown that the traditional Chinese medicine composition has obvious in vivo anti-respiratory syncytial virus effect, which may be related to its ability to regulate the balance of immune cells in the whole body and local lung tissue, and inhibit local inflammation in lung tissue.
[0382] Pharmacodynamic studies have confirmed that the traditional Chinese medicine composition provided in the present application has the effects of eliminating pathogenic factors, supporting healthy qi, overall regulation, simultaneous treatment of lung and defensive qi, and active intervention.
[0383] Eliminating pathogenic factors and supporting healthy qi, overall regulation: research has confirmed that LHQG can not only effectively eliminate pathogens, but also mobilize immune function. In vitro anti-viral pharmacodynamic studies have confirmed that LHQG has in vitro anti-viral effects on multiple strains of influenza A virus, influenza B virus, respiratory syncytial virus, and coronavirus, and acts on the early stage of viral replication. In vivo pharmacodynamic studies have further confirmed that LHQG has obvious in vivo anti-influenza A virus and anti-respiratory syncytial virus effects, and can increase the CD4 + / CD8 + ratio in peripheral blood and lung tissue, reduce the M1 / M2 ratio of lung macrophages, enhance the body's resistance to external viral infection, mobilize the anti-disease immune function, and prevent the occurrence of repeated upper respiratory tract infections. LHQG not only effectively resists cold viruses, but also targets cold-related clinical symptoms, and plays a comprehensive therapeutic role in relieving fever, relieving pain, reducing phlegm, and relieving cough.
[0384] Simultaneous treatment of lung and defensive qi, active intervention: LHQG can significantly reduce the expression of host cell inflammatory factors induced by influenza virus and LPS, and has a clear in vitro anti-inflammatory effect. In in vivo experiments, it effectively reduces the levels of IL-1β, TNF-α, IL-10, and INF-γ in the lungs of respiratory syncytial virus-infected mice, protects the alveolar wall structure, reduces the degree of inflammatory cell infiltration, reduces the thickness of lung interstitium, and improves lung pathological damage. At the same time, it effectively inhibits the lung inflammation caused by cold, reduces the level of inflammatory factors, improves lung pathological damage, treats cold, and prevents the development to pneumonia.
[0385] From the above data, it can be seen that the traditional Chinese medicine composition provided in the embodiments of the present application has the effect of treating children's cold, 11 kinds of medicines, the monarch, minister, and assistant complement each other, the whole prescription coordinates external relieving exterior and internal clearing lung heat, and combines clearing and tonifying.
