Objective To investigate the clinical efficacy of combined acupuncture and medicine in treating kidney deficiency and phlegm dampness syndrome in obese polycystic ovary syndrome. Method Sixty-four patients were randomly allocated to two groups. The treatment group received combined acupuncture and medicine and the control group, oral administration of metformin. The course of treatment was three months. Pre-treatment and post-treatment indicators were statistically analyzed in the two groups of patients. Result BMI, waist to hip ratio, fasting insulin, fasting blood glucose and HOMA-IR improved significantly in the treatment group of patients after treatment; there were statistically significant pre-/post-treatment differences (P<0.05). Post-treatment BMI and waist to hip ratio improved more markedly in the treatment group than in the control group (P<0.05). Conclusion Combined acupuncture and medicine has a better therapeutic effect on kidney deficiency and phlegm dampness syndrome in obese polycystic ovary syndrome.

Objective: Extracting ephedrine and berberine from the water extract of Ephedra Herba and Rhizoma Coptidis. Methods: Modified PVA was used as separating membrane and separated alkaloids. Results: A colorless ephedrine aqueous solution was obtained when extraction time was less than 8 hours; while a three constitution solution was obtained when time of extraction is over 8 hours. So is Rhizoma Coptidis. The membrane is hardly fouled. Conclusion: Purity of alkaloids from Herba Ephedra and Rhizoma Coptidis by membrane separation is Superior to that by alcoholic sediment but amount of alkaloids is reverse.

Objective To explore the effect of hepatitis B virus(HBV) on the expression of apolipoprotein B(ApoB) and its regulatory mechanism. Methods mRNA and protein expression of ApoB in HepG2 and HepG2.2.15 cells was measured by RT-PCR and Western blot, serum ApoB levels in patients with HBV infection and in healthy individuals were measured by biochemical analyzer Olympus 5400, the expression of ApoB difference among healthy individuals, patients with chronic hepatitis B, liver cirrhosis, and hepatocellular carcinoma were analyzed, HBV infectious clone pHBV1.3 was tranfected into HepG2 cells,and expression of ApoB and microsomal triglyceride transfer protein(MTP) was measured by RT-PCR and Western blot. Results Expression of ApoB mRNA and protein was lower in HepG2.2.15 cells than in HepG2 cells, serum apoB levels was much lower in patients with chronic hepatitis B and liver cirrhosis as compared to healthy individuals( P ＜0.05 ), HBV could inhibit the expression of ApoB and MTP at mRNA and protein levels. Conclusion HBV may downregulate the synthesis and secretion of ApoB via inhibits the expression of MTP.

ObjectiveTo investigate the effect of N-acetylcysteine on lung injury induced by cardiopulmonary bypass(CPB) in dogs.MethodsThirty-six healthy adult mongrel dogs of both sexes weighing 15-16 kg were randomly assigned into 2 groups (n =18 each):CPB group (group C) and N-acetylcysteine group(group N).Lung injury was produced by CPB.In group N N-acetylcysteine 150 mg/kg was injected iv immediately before CPB,followed by infusion at 20 mg· kg-1 · h-1 until 60 min after termination of CPB.Blood samples were taken from femoral artery before CPB (T0,baseline),30 and 60 min after termination of CPB (T1,T2 ).Oxygenation index ( OI =PaO2 ÷ FiO2 ) and respiratory index (RI =PA-(a) DO2 ÷ PaO2 ) were calculated.Six animals were sacrificed at each time point.Lung specimens were obtained for microscopic examination,and determination of transforming growth factor-β1 (TGF-β1) mRNA expression,MDA content and SOD activity.ResultsCPB significantly increased RI,MDA content and TGF-β1 mRNA expression and decreased OI and SOD activity at T1 and T2 as compared with the baseline values at T0 in group C.N-acetylcysteine administered before and during CPB significantly attenuated CPB-induced above changes in OI,RI,MDA content,SOD activity and TGF-β1 mRNA expression.Microscopic examination showed that N-acetylcysteine significantly ameriorated CPB-induced lung damage.ConclusionsN-acetylcysteine administered before and during CPB can attenuate CPB-induced lung injury by inhibiting lipid peroxidation response and down-regulating TGF-β1 expression.
