We expressed B cell epitopes of dengue virus envelope protein and NS1 protein in prokaryotic cells,and purified and evaluated for its serological activities.A recombinant multi-epitope chimeric gene named rE including eight B cell epitopes was connected by linker peptide (EAAAK)2 and cloned into prokaryotic expression vector pET-28a(+),and transformed into E.coli BL21(DE3) cells for expression under induction of IPTG.The expressed recombinant protein was purified with 6× His purification media,and identified by SDS-PAGE and Western blot,and its antigenicity was analyzed by using an indirect ELISA assay.The recombinant expression vector pET28a-rE was constructed and expressed in BL21 (DE3) successfully,but the recombinant proteins mainly appeared as inclusion bodies.The target protein was obtained with high purity through the purification of affinity chromatography.SDS-PAGE and Western blot analysis showed that the molecular weight of fusion protein was in the expected line.The established indirect ELISA has high accuracy.This recombinant peptide antigen expressed in E.coli has good potential for serum testing.

To observe the hypoglycemic effect of Qizhi Jiangtang capsule in rats with type 2 diabetes, and investigate the preliminary mechanism of its hypoglycemic effect, type 2 diabetes rat models were established by high glucose and high fat combined with small dose of streptozotocin (STZ). After continuous administration for 6 weeks, blood glucose, and glycosylated serum protein (GSP) levels were detected in all of the animals; immunohistochemistry assay was used to detect the number of islet β cells; Western blot assay was used to detect the protein expression levels of insulin receptor (InsR), phosphoinositide-3 kinases (PI3K), glucose transporter-2 (GLUT2) and phosphorylated Jun N-terminal kinases (p-JNK)in hepatic tissues. The results showed that Qizhi Jiangtang capsule could reduce the blood sugar and GSP levels in serum in animals with type 2 diabetes mellitus, increase the level of insulin in serum and number of islet β cells, increase the protein expression levels of InsR, PI3K and GLUT2, and reduce the level of p-JNK protein expression. In conclusion, Qizhi Jiangtang capsule has relatively stable hypoglycemic effect, and the mechanism may be associated with increasing the number of islet β cells and level of insulin in serum, up-regulating the protein expression levels of InsR, PI3K and GLUT2, down-regulating the level of p-JNK protein expression in hepatic tissues, and reducing the level of insulin in hepatic tissues.

The effect of Qizhi Jiangtang vapsule (QJC) on degree of dermal ulcer cicatrization in 2 type diabetic rats was studied. Except the rats for blank group, other male Wistar rats were used to establish type 2 diabetic model by feeding with high sugar and high fat diet for four weeks and intraperitonally injecting with 30 mg•kg⁻¹ streptozotocin (STZ). After that, the rats were divided into balanced groups according to blood sugar, and received corresponding drugs for treatment for 8 weeks. At the end of week 8, 2 cm diameter circular incision was done on the back of rats. After that, the rats were administered continuously for10 days. Area of ulcer surface was detected every two days. After the last administration, wound granulation tissues were cut down to conduct pathological examination and detect the expression of VEGF, PI3K, p-ERK protein in wound tissues. The results showed that compared with the model group, after application of Qizhi Jiangtang capsule (2.24 g•kg⁻¹), the wound was significantly reduced on day 6 and day 10 of wound formation; inflammation reaction on ulcer surface was significantly reduce; Qizhi Jiangtang capsule can increase VEGF expression in the wound tissues of diabetic rats, and inhibit ERK phosphorylation. It can be concluded that Qizhi Jiangtang capsule can promote skin ulcer healing for diabetes rats, and its mechanism may be related to regulating the expression of VEGA and p-ERK proteins.

Objective::To explore the feasibility of the rapid identification system(MALDI-Biotyper System) of microorganisms for rapid identification of Pseudomonas aeruginosa and clinical isolation of Staphylococcus aureus. Method::Identification quality control and clinical isolation were conducted for drug resistance of S. aureus by microbial rapid identification system and broth dilution method. The scores of microbial rapid identification system were compared with the MIC value of broth dilution method. The drug resistance of P. aeruginosa was simultaneously identified to determine the accuracy and applicability of the rapid identification system of microorganisms. Result::The scores of the microbial rapid identification system showed that the score of sensitive quality control strain S. aureus was higher than 2.000, and the that of resistant strain of methicillin-resistant S. aureus(methicillin-resistant S. aureus, MRSA)was between 1.700 and 2.000.The score of clinically isolated S. aureus was between 1.700 and 2.000, which suggested the drug resistance and was consistent with the MIC value of the broth dilution method. At the same time, the systemic identification value of the P. aeruginosa, which is independent of the quality control sensitive strain, was greater than 2.000, showing sensitivity and it was a sensitive strain itself, which was consistent with the results. Conclusion::The microbial rapid identification system scoring method can be used for the rapid identification of the drug resistance of S. aureus and P. aeruginosa.
