This article was aimed to study the effect ofXiao-Qing-LongDecoction (XQLD) on plasma AngⅡ, ALD, Na+-k+-ATPase content, and plasma AT1 and AT2 mRNA expressions in Cor pulmonale rats, in order to further explore the mechanism of ventilating lung qi for diuresis. A total of 60 Wistar rats were randomly divided into the normal group, model group and XQLD, with 20 rats in each group. The enzyme-linked immunosorbent assay (ELISA) method was used to determine the AngⅡ, ALD and Na+-k+-ATPase content. The fluorescence quantitative PCR was used to detect the AT1 and AT2 mRNA expression. The results showed that compared with the normal group, the AngⅡ, ALD and Na+-k+-ATPase contents in the model group were significantly increased (P< 0.05, orP< 0.01). Compared with the model group, the AngⅡ, ALD and Na+-k+-ATPase contents in the XQLD group were obviously decreased (P< 0.05). Compared with the normal group, AT1 mRNA expression was increased; and AT2 mRNA expression was decreased in the model group (P<0.05, orP< 0.01). Compared with the model group, AT1 mRNA expression was decreased; and AT2 mRNA expression was increased in the XQLD group (P < 0.01). It was concluded that XQLD can effectively regulate the AT1 and AT2 mRNA expressions, influence ALD content to ventilate lungqi for dieresis.

Objective To observe the effects of Liuwei Buqi capsules on CD4+CD25+forkhead box protein 3+(Foxp3+)regulatory T cells(Tregs),helper T cells(Ths)in patients with chronic obstructive pulmonary disease (COPD). Methods Eighty COPD patients admitted into the First Affiliated Hospital of Anhui University of Traditional Chinese Medicine from January 2012 to May 2013 were randomly divided into a traditional Chinese medicine (TCM)experimental group(40 cases)and a western medicine control group(40 cases);there were 40 research volunteers enrolled as healthy controls. After admission,both the TCM experimental group and western medicine control group were given conventional western medicine comprehensive treatment. Additionally,in the TCM experimental group,Liuwei Buqi capsules were given orally once 3 pills(0.4 g/pill)and twice a day,while in the western medicine control group nifedipine was given,once 10 mg and 3 times a day,30 days constituting one therapeutic course for both groups. BODE evaluation means that the body mass index(B),the degree of airflow obstruction(O),the scores of dyspnea(D)and excercise capacity(E)of COPD patients were evaluated. A spirometer was used to observe the changes in the patient's pulmonary function to detect the dyspnea score. The γ-interferon(IFN-γ),interleukin (IL-4 and IL-17)in serum were detected by enzyme-linked immunosorbent assay(ELISA). The expression of Treg of peripheral blood was detected by flow cytometry. Results Compared with healthy control group,lung function parameters,IL-4,CD4+CD25+Treg and CD4+CD25+Foxp3+Treg of peripheral blood were increased,while dyspnea score,BODE score,the expressions of IFN-γ,Th1/Th2,IL-17 in serum were decreased significantly in the COPD group(P<0.05 or P<0.01). After treatment,compared with those before treatment in the two groups, the forced expiratory volume in 1 second(FEV1),FEV1/forced vital capacity(FVC),IL-4,CD4+CD25+Treg, CD4+CD25+Foxp3+ Treg were all increased,while dyspnea score,BODE score,IFN-γ,Th1/Th2,IL-17 were all decreased(P<0.05 or P<0.01),and the peak expiratory flow(PEF)was decreased in western medicine control group and increased in TCM experimental group. After treatment,the comparisons of ratio of FEV1/FVC〔(78.12±14.96)%vs.(67.52±10.39)%〕,BODE score(1.07±0.72 vs. 1.77±0.74),IL-17(μg/L:40.80±8.97 vs. 48.22±6.51) Th1/Th2(1.05±0.23 vs. 1.42±0.21)and CD4+CD25+Foxp3+ Treg〔(6.61±2.26)% vs.(5.25±2.03)%〕between the two groups were all of statistical significant difference(all P<0.05). Conclusion Liuwei Buqi capsules can improve COPD symptoms by up-regulating the expressions of CD4+CD25+Foxp3+ Treg,IL-4,and down-regulating the expressions of IFN-γ,IL-17 to correct the balance of Th1/Th2 in patients with COPD.

BACKGROUND: Studies have confirmed that Atorvastatin drugs can increase the number of endothelial progenitor cells significantly in vitro, as well as the content of vascular endothelial growth factor(VEGF). OBJECTIVE: To investigate the effect of Atorvastatin on VEGF expression in necrotic femoral heads of rabbits. DESIGN, TIME AND SETTING: The randomized controlled animal experiment was performed at the Department of Orthopedic Surgery, Renmin Hospital of Wuhan University, from September 2007 to November 2008. MATERIALS: Forty-five male and female healthy New Zealand white rabbits weighing 2.5-3.5 kg were randomly divided into normal control group, model control group and AtorvastaUn group, 15 rabbits in each group. METHODS: Nitrogen refrigeration was used to develop femoral head necrosis models of rabbits in the model control and Atorvastatin groups. Two weeks after modeling, the animals in the Atorvastatin group were administered intragastically with Atorvastatin, normal control and model control group were treated with the same volume of normal saline. MAIN OUTCOME MEASURES: Each five rabbits were sacrificed at the 4th, 8th, and 12th weeks respectively for general observation, X-ray and histological observation. VEGF protein expression was assessed by immunohistochemistry method and VEGF mRNA level was assessed by reverse transcription - polymerase chain reaction method. RESULTS: The VEGF protein and mRNA levels in the model control and Atorvastatin groups were obviously lower than those in the normal control group, while the VEGF protein and mRNA levels in the Atorvastatin group were much higher than those in the model control group at the 8th and 12th weeks alter the treatment with Atorvastatin (P < 0.05). CONCLUSION: Atorvastatin can significantly upregulate the expression of VEGF, which is probably an effective clinical treatment to avascular necrosis of the femoral head.
