Anti-schistosomiasis monoclonal antibody NP11-4 single-chain antibody, preparation and use thereof

The invention discloses a single-chain antibody of an anti-schistosome monoclonal NP11-4 as well as a preparation method and application thereof, and relates to the field of gene engineering and the field of therapeutic drugs against schistosomiasis. The invention is to use a monoclonal antibody NP11-4 located at adult membrane, cercaria memberane, schistosomulum membrane, egg shell and miracidium in egg of Schistosoma japonicum, extract total RNA of hybridoma cells through a gene engineering technology, adopt RT-PCR for proliferation of genes VH and VL, and use overlap-extension PCR to connect the genes VH and VL into a single-chain antibody gene in the form of VH<-linker-VL, which is subsequently connected with a pBAD / gIIIA carrier and cloned into Top10F'of Escherichia Coli to induce a soluble expression of the target gene. The zone from amino acid No.1 to No. 122 of the expressed single-chain antibody of the anti-schistosome monoclonal NP11-4 is a heavy chain gene repertoire of the single-chain antibody (VH), and the zone from the amino acid No.141 to No.254 is a light chain gene repertoire (VL) of the single-chain antibody, wherein the linker between the heavy and light chain gene repertoires consists of 18 amino acids including repeated glycines and serines, and the single-chain antibody has 254 amino acids in full length.

Nauclea offcinalis extract and application of nauclea offcinalis extract for treating pelvic inflammation

The invention discloses a nauclea offcinalis extract, which is prepared by the following steps: grinding the nauclea offcinalis into coarse powder, feeding into an extraction kettle, adopting supercritical carbon dioxide to extract, and collecting extracts to obtain a supercritical extract; carrying out water extraction on the supercritical dregs, and condensing to obtain a water extract; combining and uniformly mixing the water extract and the supercritical extract to obtain the nauclea offcinalis extract; drying the nauclea offcinalis extract to obtain dried plaster powder, and preparing the dried plaster powder to the necessary dosage form. Additionally, the invention discloses an application of the nauclea offcinalis extract in treatment of pelvic inflammation. The invention has the following advantages: the prescription provided by the invention is more significant in treatment effect, the improved situation of the pelvic inflammation is better than a control group, thereby showing that the treatment effect of the prescription for the pelvic inflammation is better than that of the Western medicine metronidazole. Due to the fact that the pelvic inflammation is easy to relapse, so that the long-term medication is needed, but most Western medicines are based on antibiotic treatment, the side-effect is high and the drug resistance is easy to produce; however, the Chinese patent drug is low in the side-effect and suitable for the long-term medication, thereby being fitting for the characteristic that the pelvic inflammation is easy to relapse; and the prescription provided by the invention is appropriate for the long-term treatment of the pelvic inflammation.

Traditional Chinese medicine composition for treating type II diabetes and preparation method of traditional Chinese medicine composition for treating type II diabetes

The invention discloses a traditional Chinese medicine composition for treating type II diabetes. The traditional Chinese medicine composition is prepared from, by weight, 13-17 parts of Radix Rehmanniae Preparata, 8-12 parts of Herba Dendrobii, 4-8 parts of Rhizoma Coptidis, 1-5 parts of Rhizoma Zingiberis, 8-12 parts of Fructus Mume, 13-17 parts of Radix Ginseng, 8-12 parts of Herba Gynostemmatis Pentaphylli, 4-8 parts of Pheretima, 4-8 parts of Bombyx Batryticatus and 4-8 parts of Radix Glycyrrhizae. The traditional Chinese medicine composition has efficacies of internal organ nourishing, Qi movement regulating, blood glucose reducing, stasis removing and the like and is capable of making the five internal organs tough and coordinated through Qi tonifying and harmonizing of the five internal organs; by combination of syndrome differentiation and five-element five-flavor theories for treating diabetes, main clinical symptoms of patients suffering from type II diabetes with deficiencyof both Qi and Yin can be effectively improved; in addition, effectiveness in blood sugar reduction and glucostasis control can be achieved, and safety in use, freeness of toxic and side effects andavailability for long-term utilization are realized.
