In this study, we investigated the effect of Cigu Xiaozhi formula on HSC-T6 activity in hypoxic microenvironment based on network pharmacology and computer-aided drug design, and predicted and verified its possible targets and related signaling pathways. The potential active components and targets of Cigu Xiaozhi formula were screened by searching Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), Encyclopaedia of Traditional Chinese Medicine (ETCM) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine (BATMAN-TCM) databases, and the liver fibrosis related targets retrieved from Gene Cards and Pharm GK database were integrated to obtain the potential targets of Cigu Xiaozhi formula in the treatment of liver fibrosis. GO enrichment analysis and KEGG signaling pathway enrichment analysis were performed on Omic Share platform, and Cytoscape software was used to construct the "potential active ingredient-key target-pathway" network. The active components and target proteins were subjected to molecular docking analysis by Auto Dock software. According to the results of molecular dynamics simulation and binding free energy calculation, the top 5 active components with degree were scored. The active components stigmasterol and β-sitosterol were subjected to molecular docking. CoCl₂ was used to induce HSC-T6 cells to construct hypoxia model in vitro. The cell viability was detected by CCK-8 assay, and the optimal time and concentration of hypoxia model of HSC-T6 cells was determined to be 100 µmol·L^-1 CoCl₂ for 24 h. Under hypoxia condition, HSC-T6 cells were activated, the wound healing rate was significantly increased, and the fluorescence signal of activation marker protein α-smooth muscle actin (α-SMA) was significantly enhanced. However, 6% drug-containing serum could inhibit the activation of HSC-T6 cells, and the wound healing rate was significantly decreased, and the fluorescence signal of α-SMA was significantly weakened. Further studies showed that the expressions of hypoxia-inducible factor-1α (HIF-1α), α-SMA and key proteins of Hedgehog (Hh) signaling pathway in HSC-T6 cells were up-regulated under hypoxia, while the expressions of HIF-1α, α-SMA, Patched-1 (Ptch-1) and glioma related oncogene homology-1 (Gli-1) were down-regulated in 6% drug-containing serum group, the YC-1 group and the cyclopamine group. These results indicated that HIF-1α and Hh signaling pathways were involved in the activation of HSC-T6 cells, and the traditional Chinese medicine Cigu Xiaozhi formula could inhibit the activation of HSC-T6 cells, and the mechanism may be related to the inhibition of HIF-1α expression and the blocking of Hh signaling pathway. In conclusion, Cigu Xiaozhi formula can inhibit the activation of HSC-T6 cells by directly acting on HIF-1α and Hh signaling pathway, and exert an anti-hepatic fibrosis effect. The animal experimental protocol has been reviewed and approved by Laboratory Animal Ethics Committee of Gansu University of Chinese Medicine, in compliance with the Institutional Animal Care Guidelines.

Objective To assess the perioperative change in Quality of Life(QoL)in patients who underwent CABG surgery. Methods The Chinese version of the SF-36 and SAQ were sent to participants at baseline and three and six months after CABG sur- gery.Results Angina stability score,one of the five SAQ domains,was lowest and postoperative SAQ domains scores were with sig- nificant improvement from baseline.Many of the dimensions of the SF-36 in postoperative patients were better than baseline.The SF- 36 was also used to evaluate in groups ONCAB and OPCAB,but no difference of the SF-36 subscale scores between the two groups was observed.Conclusion SAQ domains scores were significantly improved in three months and increased further in six months.Many of the dimensions of the SF-36 in postoperative patients were improved than baseline.No difference of the SF-36 subscale scores between the groups of ONCAB and OPCAB was observed postoperatively.

OBJECTIVE: To detect the levels of index related to inflammation such as soluble CD40 ligand (sCD40L), neutrophil collagenase-8 (MMP-8), and pregnancy associated plasma protein-A (PAPP-A) , lipid peroxidation and autoimmune indexes such as oxidized low density lipoprotein (ox-LDL) and its antibody (ox-LDL Ab) in patients with coronary heart disease, and to investigate its relationship with acute coronary syndrome (ACS). METHODS: Contents of sCD40L, MMP-8, PAPP-A, ox-LDL and ox-LDL Ab in the peripheral blood were measured by enzyme-linked immunosorbent assay from 109 patients with coronary heart disease including 36 acute myocardial infarction (AMI), 38 unstable angina pectoris (UAP), and 35 stable angina pectoris (SAP) and 36 controls without coronary heart disease. RESULTS: The levels of each index in the peripheral blood of ACS patients (including AMI and UAP) were higher than those of SAP patients and controls (P < 0.05), and the difference of each index between UAP group and AMI group in ACS patients had no statistical significance (P > 0.05). The levels of each index of SAP patients, except PAPP-A, were all higher than those of controls (P <0.05). All the indexes were helpful in diagnosis of ACS. The area under the ROC curve of each index is between 0.7 and 0.9. CONCLUSION The increase of sCD40L, MMP-8, PAPP-A, ox-LDL and ox-LDL Ab levels in peripheral blood may be related to the pathogenesis of ACS, and can be used as potential markers of unstable atherosclerosis plaque.

To explore the new approach to prevent graft versus host disease (GVHD) by purging ex vivo T lymphocytes of bone marrow graft through Fas-FasL way, FasL-cDNA was transfected into BALB/c mouse bon e marrow cells by liposome ex vivo. The transfected cells were cultured together with BAC (BALB/c x C57BL/6) mouse bone marrow graft. The mixing bone marrow graft was infused into BALB/c mouse recipients after 60Co-gamma irradiation. The mortality, manifestation and pathologic change of GVHD in recipient mice were observed. The CFU-S and Y chromosome from donor mice were detected. The results showed that compared with control group, the mortality in 60 days of the recipients in the experimental group decreased (20% vs 70%, P < 0.01) and the morbidity of GVHD lowered (40% vs 100%, P < 0.01). The CFU-S counts for all groups were at normal level on 20 days after transplantation. The Y chromosome from donor mice was discovered in 70% bone marrow nucleated cells of recipient mice survived over 2 months in the experimental group. It is concluded that mFasL-cDNA transfected mouse bone marrow cells prevent GVHD after culturing together with bone marrow graft, and accelerate hematopoietic reconstitution in recipient mice.

OBJECTIVETo investigate the protective effects of oxymatrine on chronic heart failure induced by isoproterenol (ISO) and to observe its effects on ADMA metabolism pathway in ISO-induced chronic heart failure in rats.

METHODMale Sprague-Dawley rats were given oxymatrine (100,50 mg kg-1) orally for 14 days. Heart failure was induced in rats by subcutaneous injection of isoproterenol (5 mg kg-1 d-1 ) at the 8th day for 1 week. Serum parameters, haemodynamic parameters, Heart weight, and histopathological variables were analysed. Expression of protein levels were measured by Western blot.

RESULTOxymatrine (100,50 mg kg-1) significantly attenuated serum content of cTn I, improved left ventricle systolic and diastolic function and left ventricular remodeling, reduced the ISO-induced myocardial pathological changes compared with ISO group. In addition, oxymatrine (100,50 mg kg-1) significantly reduced serum level of ADMA (P <0. 01), normalize the reduced dimethylarginine dimethylaminohydrolase 2 (DDAH2) expression (P <0. 01) , but had no effect on the isoproterenol-induced upregulated protein arginine methyltransferases 1 expression.

CONCLUSIONOxymatrine could ameliorate the experimental ventricular remodeling in ISO-induced chronic heart failure in rats and the mechanism involved in reducing serum content of ADMA and increased DDAH2 expression.

Objective To investigate the attitudes of urban and rural community members toward total banning on smoking in public places and to explore the factors associated with these attitudes, in three counties/cities in China. Methods A cross-sectional study was conducted in three counties/cities in 2004, including Xin' an county of Henan province, Anyi county of Jiangxi province, and Mianzhu city of Sichuan province. A total of 5642 residents at age of 18-69 years old were interviewed face-to-face with a uniform questionnaire by locally-trained interviewers, through a random three-stage stratified sampling in each county. Factors were assumed to be associated with attitudes, using chi-square test in univariate analysis and non-conditional logistic regression model in multivariate analysis. Results The prevalence of current smoking among respondents was 44.3%. 80.7% (1379/1709) of the current smokers reported smoking often or sometimes in public places. Only 9.6% (479/4983) of the respondents reported that their indoor workplaces had totally banned on smoking. 43.5% of the respondents supported a total smoking ban strategy in pubic venues. The results of multivariate logistic regression model showed that eight factors were significantly associated with support for the total smoking ban in public places included region, residency, age, gender, education, smoking status, awareness about passive smoking hazards, and hearing of any message on tobacco control through media differences of rates regarding the factors as: residents in urban to rural areas (OR=1.29), elderly to youngsters (30-49 vs. 18-29, OR=1.46; 50-69 vs. 18-29, OR=1.71), female to male(OR=1.27), high-educated to less-educated ones, quitters to current smokers (OR=1.90), nonsmokers to current smokers (OR=2.01). Those who know messages on health hazards of passive smoking (OR=2.26), or heard of message on tobacco control through media (OR= 1.43). Conclusion Results from our study revealed that a thorough smoke-flee policy in public places should be developed and implemented in these three counties/cities.

OBJECTIVETo describe knowledge, attitudes and behaviors on infectious diseases in different Chinese populations by their education levels, occupation and residential districts.

METHODSData regarding awareness of the transmission routes and prevention strategies on hepatitis, sexually transmitted diseases (STD), acquired immune deficiency syndrome (AIDS) and prevalence rates on a) self-reported STD b) seeking treatment for STD c) source of knowledge on AIDS prevention, were calculated based on results from 17 questions of BRFS questionnaire by weight on age structures from 2000 census.

RESULTSMost people realized that hepatitis, STD and AIDS were important issues in public health. However, their awareness on the transmission routes of these diseases was not satisfied. Moreover, due to the fear of these diseases, 27.6% and 30.1% of the people studied thought that shaking hands with STD patients and HIV carriers could get infected. 9.9% of the people reported that they ever used a condom during the past year. 2.2/1000 of the people reported that they had ever suffered from STD during the past 5 years, with 3.4/1000 in males, 0.9/1000 in females, 4.2/1000 in urban population and 1.6/1000 in rural population. Among these STD patients, 75.0% of them reported that they had ever received treatment in a STD clinic including 38.2% of them reporting that they had ever received treatment in private clinics without license, and 6.7% of them reported that they had ever treated by drugs bought by themselves. 47.0% of people reported that they had received health education materials or information on AIDS prevention from medical workers or through media. 12.1% of the people had been informed that condom use could prevent from STD and AIDS transmission.

CONCLUSIONThe awareness on hepatitis, STD and AIDS was quite insufficient in the Chinese general population, especially in rural and western part of China. With the development of AIDS epidemic from people with high risk behavior to the general population, China will undertake tremendous disease burdens from AIDS in the future.

OBJECTIVETo investigate the clinical characteristics of methicillin-resistant Staphylococcus aureus (MRSA) in phlegm specimens of positive patients, so as to provide evidences for the nosocomial infection control.

METHODSWe retrospectively analyzed the clinical data of 211 hospitalized patients who were MRSA-positive in their phlegm specimens in PUMC Hospital from January 2005 to October 2007.

RESULTSAmong the 211 patients, 196 (92.9%) had received antibiotics three months before the detection of MRSA, and 128 (60.7%) had received more than three antibiotics. Over 90% of MRSA were resistant to levofloxacin, erythromycin, clindamycin, and gentamicin, and 73.9% were resistant to rifampicin.

CONCLUSIONSImproper use of antibiotics should be avoided. Vancomycin is the first choice for MRSA treatment.
