Example Embodiment

[0050] Example 1 Effect of Psoralen on OGTT and HOMA-IR in juvenile fatty liver mice

[0051] 1. Oral glucose tolerance test (OGTT) method

[0052] First, the OGTT experiment was performed on the mice 3 days before sacrifice. The mice were fasted for 12 hours, and blood samples were collected by cutting the tail and taking blood. The fasting blood glucose (FBG) value was measured with a Roche blood glucose meter / excellent type. After that, the mice were given 50% glucose 2g / kg by gavage, and then the tail was cut again to take blood. The instrument measures blood glucose (PG-1h, PG-2h) values ​​1h and 2h after intragastric administration.

[0053] 2. Method of calculating insulin resistance index (HOMA-IR)

[0054] 1) Fasting blood glucose (FBG) was measured by glucose oxidase method, and fasting insulin (FINS) was measured by ELISA method. Calculate HOMA-IR according to the formula: FBG(mmol / L)×FINS(mIU / L) / 22.5.

[0055] 3. Results

[0062] Example 2 Effect of psoralen on blood lipids in juvenile fatty liver mice

[0063] 1. Method

[0064] The mice were fasted for 12 hours before being sacrificed, and then the eyeballs were removed to collect blood samples, the blood volume was 2-3ml, centrifuged at 3000r / min for 30min, the serum was separated, and the blood TC value, TG value and HDL-C value were determined by enzymatic method.

[0065] As shown in Table 2: Compared with the normal group, the model mice developed dyslipidemia, and the serum TG value, TC value and LDL-C value increased significantly (p <0.01), and the serum HDL-C level was significantly reduced (p <0.01); Compared with the model group, the individual blood lipid levels of each dose group of psoralen and the vitamin E group were improved to varying degrees (p <0.01, p <0.05), among which the high-dose psoralen group improved the most significantly (p <0.01), the difference was statistically significant in the lower dose group (p <0.01, p <0.05).

[0070] Example 3 Effect of psoralen on liver morphology of juvenile fatty liver mice

[0071] 1. Method

[0072] a. Material handling:

[0073] The mice were fasted for 12 hours before being sacrificed, and liver tissues were taken. The right middle lobe, upper right lobe and lower right lobe of the liver were fixed with 4% paraformaldehyde, embedded in paraffin, and used for hematoxylin-eosin (HE) detection as backup;

[0074] b. Hematoxylin-Eosin (HE) staining

[0075] Take paraffin sections, deparaffinize with xylene, hydrate with gradient ethanol, rinse with deionized water, stain with hematoxylin for 1-5min, rinse with deionized water for 2min, differentiate with 1% hydrochloric acid and alcohol for 15sec, rinse with deionized water for 1min, and pan with 1% ammonia water Blue 30sec, deionized water rinse for 1min, eosin staining for 30sec, deionized water rinse for 30sec, gradient ethanol dehydration, xylene transparent, dry, neutral gum mount, and observe in an optical microscop...

Abstract

The invention relates to the technical field of medicine, and concretely relates to an application of psoralea corylifolia in preparation of a medicine for treating children fatty liver. The psoralea corylifolia can improve fatty liver of young mice, wherein the curative effect presents in a dose-dependent manner; can improve early hepatic fibrosis of young mice with fatty liver, wherein the curative effect presents in the dose-dependent manner; and can inhibit the NF(nuclear factor)-kB inflammatory pathway activation, wherein the curative effect presents in the dose-dependent manner. By establishing a young mice NAFLD model, the psoralea corylifolia has the effect for inhibiting the hepatic tissue NF-kB activity, and has prevention and treatment effects for children fatty liver. The psoralea corylifolia can be combined with other compounds for preparing a medicinal preparation for treating children fatty liver.

Description

technical field [0001] The invention relates to the technical field of medicine, in particular to the application of psoraleae in the preparation of medicines for treating fatty liver in children. Background technique [0002] Nonalcoholic fatty liver disease (NAFLD) presents a trend of globalization and younger age prevalence, and is the primary cause of children seeking gastroenterology or liver disease specialists. Obesity is closely related to fatty liver. The prevalence of childhood obesity in my country is an objective fact. The prevalence of NAFLD in obese children is as high as 68.2%. NAFLD originating in childhood is the main reserve group for adult liver cirrhosis and metabolic syndrome-related components. With the process of urbanization in my country, the rise of middle-class families and the full opening of the "two-child" policy, NAFLD has spread rapidly and has replaced chronic viral hepatitis as a major problem threatening the health of children in my countr...
