This study is to investigate the effects of paeoniflorin on cerebral blood flow and the balance of PGI2/TXA2 of rats with focal cerebral ischemia-reperfusion injury. A total of 72 SD rats (3) were randomly divided into 6 groups: sham operation group, cerebral ischemia-reperfusion model group (I/R gourp), low (10 mg.kg-1), middle (20 mg.kg-1) and high (40 mg.kg-1) doses of paeoniflorin groups and nimrnodipine group. Focal cerebral ischemia in rats was made by inserting a monofilament suture into internal carotid artery for 90 min and then reperfused for 24 h. The effects of paeoniflorin on neurological deficit scores and the infarction volume of brain were detected. Relative regional cerebral blood flow (rCBF) was continuously monitored over ischemic hemispheres by laser-Doppler flowmetry (LDF). The expression of COX-2 in hippocampal CAl region was estimated by immunohistochemistry and the contents of prostacyclin I2 (PGI2), thromboxane A2 (TXA2), and ratio of PGIJ2/TXA2 in serum were measured by ELISA kits. Paeoniflorin significantly ameliorated neurological scores, reduced the infarction volume, and increased regional cerebral blood flow relative to the I/R group. In addition, paeoniflorin could inhibit COX-2 expression and the release of TXA2 and prevent the downregulation of PGI2 induced by I/R injury. The neuroprotective effects of paeoniflorin against focal cerebral ischemia-reperfusion rats might be attributed to improve the supply of injured hemisphere blood flow and adjust the balance between PGI2/TXA2.

The efficacy of patients infected with hepatitis C virus complicated with cirrhosis is not promising after treated with present standard therapy. With more and more new drugs against hepatitis C virus, many new regimens for the patients with chronic hepatitis C virus complicated with cirrhosis have come forth. Because the adverse reactions of the first generation HCV protease inhibi-tors telaprevir and boceprevir are severe, they are not recommended to be used in the patients with chronic hepatitis C virus complicated with cirrhosis. The other drugs, such as simeprevir, sofosbuvir and ledipasvir show good efficacy in the patients with chronic hepatitis C virus complicated with cirrhosis, however, the sustained virological response ( SVR) in the patients with chronic hepatitis C virus complicated with cirrhosis is lower than that in the patients with chronic hepatitis C virus without cirrhosis. Therefore, the regimens should be optimized in the future to narrow the gap in SVR.

The fused gene (PTH-HSA) of parathyroid hormone (PTH) gene and Human Serum Albumin(HSA) gene was amplified without linker by Overlapping PCR technology. The spliced gene was clone into Pichia pastoris secretory vector pPIC9K. With the help of promoter AOX1 and mat ? signal peptide, the PTH-HSA gene was designed to secretory expression.Linearized by restriction enzyme SalI, The recombinant plasmid pPIC9K/PTH-HSA was transformed into Pichia pastoris KM71 by electroporation. The recombinant strains which were identified by G418 and PCR analysis were induced by methanol to express protein PTH-HSA. The target protein was expressed in fermentation supernatant. Western blot analysis of the fusion protein showed that the expressed fusion protein PTH-HSA had the antigenicity of HSA.adenylate cyclase assay proved that the fused protein exhibited the bioactivity to stimulate cAMP synthesis The specific activity of broth was about 318IU/ml.

Stribild is a compound preparation composed of elvitegravir, cobicistat, emtricitabine and tenofovir. As for the first-treated AIDs patients or re-treated patients with creatinine clearance≥70ml·min-1 , it has definite clinical effect. Owing to once a day, stribild can enhance the acceptability of the patients, and as for the patients treated with other regimen complicated with diarrhea, pain in stomach and numbness in hands and feet, it also provides a good option. However, its adverse effects on kidney, liver and bone density in the long term use should be paid attention.

Objective To study antibacterial effect of formulas, borneol, honey, gentamicin in wet honey ice bedsores.Methods The third-stage infective bedsore model in rabbit were estabished with Staphylococcus aureus ( S.aureus) , Escherichia coli ( E.coli) , and Pseudomonas aeruginosa ( P. aeruginosa).The rabbits with bedsore were respectively compressed with gauze of honey+borneol, honey+gentamicin,borneol+gentamicin,borneol+gentamicin+honey, vaseline as control group.The strain identification and colony counts were observed before and after treatment.ResuIts The colony count of S.aureus, E.coli and P.aeruginosa in honey+borneol, honey+gentamicin, borneol+gentamicin, borneol+gentamicin+honey post-treatment was significantly higher than that of pre-treatment, respectively (P<0.05).The colony count of three strains in above four formulas post-treatment was significantly lower than that in vaseline group, respectively (P <0.05).The colony count of three strains in borneol +gentamicin +honey (original formula) post-treatment was significantly lower than that in the other formulas, respectively (P<0.05).ConcIusion The antibacterial effect of borneol+gentamicin+honey (original formula) is the best.

Objective To study the antibacterial effect of borneol, honey, gentamicin in Ruchuang Bingmi hydropathic compress agent.Method Staphylococcus aureus(S.aureus), Escherichia coli(E.coli), Pseudomonas aeruginosa(P.aeruginosa) were used to produce the third phase of infection decubitus animal models, respectively.Vaseline as the control group, divided into 12 groups:Vaseline-S.aureus, Vaseline-E.coli, Vaseline-P.aeruginosa;Honey-S.aureus,Honey-E.coli,Honey-P.aeruginosa;Borneol -S.aureus;Borneol -E.coli;Borneol-P.aeruginosa;Gentamicin-S.aureus;Gentamicin-E.coli;Gentamicin-P.aeruginosa;6 rabbits in each group.Honey, borneol, gentamicin was made into a gauze in treatment for decubitus .Organizations do strain identification and colony counts was observed before and after taking the treatment.ResuIts Borneol group ( F =11.059,P<0.01).,there was differences of each groups count cultured by borneol;Time ×Strains(F=11.281,P=0.009),there was no significant interaction between the two groups;gentamicin(F=7.99,P=0.000),gentamicin culture showed a difference in each group count;Time ×Strains(F=12.531, P<0.07),interaction between the two groups showed significant.Borneol has no antibacterial effects on P.aeruginosa , had a certain antibacterial activityon S.aureus and E coli;gentamicin had good antibacterial effect on the three kinds of bacteria, and against P.aeruginosa was particularly significant.ConcIusion The antibacterial activity of gentamicin is better than single herbs borneol in Ruchuang Bingmi hydropathic compress agent, honey has no antibacterial effect.
