Research on post-marketing Chinese medicine should be the systematic study from application to mechanism. Clinical evaluation is the basis of mechanism study, we can find the clue from clinical evaluation, then make a mechanism study to find the reason, then apply the results to clinic. So it is a virtuous circle. In order to achieve it, we cannot be limited to traditional Chinese medicine, we should form multi-disciplinary team under the direction of grand science thinking, try hard to put industry-university-research institute collaboration association to use, and if necessary, explore the new model of the whole nation system. An appropriate operation mechanism is very important.

Objective To study the therapeutical effect of glutathione(GL),a powerful antioxidant on the symptoms and ECG in patients with coronary heart disease and its mechanisms.Methods Eighty-five subjects with coronary heart disease were recruited(45 male and 40 female).The patients were randomized to receive GL (240 mg,ivgtt,qd,for 14 days,n=44)on the top of conventional treatment(aspirin+?-blocks+ACEI)or conven- tional treatement alone(control,n=41).The serum MDA,SOD,NO levels were determined.Electrocardio- graphy(ST stage,T wave)was examined.Results GL significantly improved clinical symptoms scores(2.0+0.5 vs control:1.5+0.5,P

OBJECTIVE To investigate distribution status and drug-resistance pathogens from infected urinary tract and offer scientific evidence for reasonably clinical usage of antibiotics.METHODS A total of 286 strains of pathogenic bacteria isolated from urinary tract were identified by common methods.Antibiotic susceptibility tests were performed by K-B methods.RESULTS Escherichia coli rated the top one,accounting for 62.2%.Results of susceptibility test showed that all pathogens were resistant to the many antibiotics in different degrees except for 100.0% sensitive to vancomycin in Gram-positive cocci and to imipenem in Gram-negative bacilli.The detection rate of extensive-spectrum beta-lactamases(ESBLs) producers in E.coli and Klebsiella pneumoniae was 36.5% and 40.9%,respectively.The average detection rate of meticillin-resistant staphylococci(MRS) was 35.7%.CONCLUSIONS The drug-resistance of pathogenic bacteria from infected urinary tract is quite serious in the local area.We should adopt effective measurement to control its prevalence.

Objective To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats. Methods The models of acute myocardial infarction were established in 16 rata by ligation of left anterior descending branch of left coronary artery through chest incision, and the animal were divided into control group(n=8) and experiment group (n=8). The hearts of another 2 rats were obtained for normal myocardial tissue sections as controls. Monoclonal antibody of ICAM-1 was infused from the caudal vein in experimental group, and no invervention was conducted for control group. Blood samples were obtained from caudal vein on the first, third, seventh and fourteenth day after operation in these two groups. Serum concentration of ICAM-1 was measured by ELISA, positive rate of CD34 cells in peripheral blood was detected by flow cytometry, and the parameters of concentration of ICAM-1 and positive rate of CD34 cells at each time point were compared between groups. Results The concentration of ICAM-1 in peripheral blood of experiment group reached the lowest of (59.01±2.22) pg/mL on the seventh day. The concentrations of ICAM-1 in peripheral blood of experiment group were lower than those in control group, and there were significant differences between these two groups on the seventh and fourteenth day(P < 0.01). The positive rate of CD34 cells in peripheral blood of experiment group reached the highest of (12±2.11)% on the seventh day. The positive rates of CD34 cells in peripheral blood of experiment group were higher than those in control group, and there were significant differences between these two groups on the third, seventh and fourteenth day(P<0.05 or P<0.01). Conclusion ICAM-1 can inhibit the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats.

Objective To explore the levels of serum leptin and insulin and their relationships with growth and development in premature infants.Methods The serum leptin and insulin concentrations of 37 premature infants were examined by the radioimmunoassay(day 1 and day 10,respectively),and anthropometric measurements were performed at birth.The blood sugar and triglyeride,cholesterol were tested at the same time.Twenty full-term newborn without severe diseases were controlled in 24 h after delivery and the level of leptin and insulin of them were detected,too.The results were analyzed by SPSS 10.0 software.Results The leptin and insulin levels in preterm infants were significantly lower than those in full-term infants[(6.45?2.24)?g/L vs(8.56?1.33)?g/L,(5.84?1.07)IU/L vs(10.85?5.24)IU/L Pa0.05).Serum leptin was positive correlation with serum insulin(Pa0.05).Conclusions Serum leptin and insulin can be the markers that reflect intrauterine nutrition status of preterm infants and the growth and development of fetus.A dipoinsular axis may be functional before 34 weeks gestation without maturity.The changes of leptin and insulin concentrations are useful for metabolism and growth in preterm infants.

Objective To investigate the effects of HepG2 and HepG2.2.15 cells steatosis on the mRNA and protein expressions of suppressors of cytokine signaling-3(SOCS-3) and sterol regulatory element binding proteins (SREBP-1c).Methods The cell model of chronic hepatitis B (CHB) combined with nonalcoholic fatty liver disease (NAFLD) was successfully constructed using an oleic acid-induced HepG2 and HepG2.2.15 cells steatosis.Cells were divided into HepG2 cell control group (HepG2 cell control group), HepG2.2.15 cell control group (HepG2.2.15 cell control group), HepG2 cell steatosis group (HepG2 cell steatosis group) and HepG2.2.15 cell steatosis group (HepG2.2.15 cell steatosis group).The expression levels of SOCS-3 and SREBP-1c mRNA were detected by real-time quantitative polymerase chain reaction (PCR).Changes in protein expressions of SOCS-3 and SREBP-1c were measured by western blot.Results SOCS-3 mRNA expression level in HepG2.2.15 cell control group was significantly lower than that in HepG2 cell control group (P<0.01).The level in HepG2 cell steatosis group was also significantly lower than that in HepG2 cell control group (P<0.01).However, the level of SOCS-3 mRNA in HepG2.2.15 cell steatosis group was lower than HepG2.2.15 cell control group with no statistical significance (P=0.173).There was interaction between cells and steatosis (F=25.547, P<0.01).The expression of SREBP-1c mRNA in HepG2.2.15 cell control group was significantly lower than that in HepG2 cell control group (P<0.01), and was significantly higher in HepG2.2.15 cell steatosis group than that in HepG2.2.15 cell control group (P<0.01).There was no significant difference between HepG2 cell steatosis group and HepG2 cell control group (P=1.000).There was interaction between cells and steatosis (F=5.04, P<0.05).Western blot analysis showed that protein levels of SOCS-3 and SREBP-1c in steatosis cells at 48 h and 72 h were significantly higher than those in non-alcoholic steatosis cells.Conclusions Protein expressions of SOCS-3 and SREBP-1c are up-regulated in both steatosis groups.Factorial analysis shows that there is interaction between cells and steatosis.HBV gene could inhibit SOCS-3 mRNA expression and promote the expression of SREBP-1c mRNA in steatosis cells.

Select patients diagnosed of hypertension in the first place in 16 hospitals and the patients were described by association rules analysis and distribution for the analysis in the study,in order to understand the information of diagnosis and treatment in hypertension patients in real world. The information include age, gender, admission condition, inpatient department, hospitalization expenses, western medicine comorbidities, the traditional Chinese medicine (TCM) syndrome and the medicine. The average age of patients was 64 years in the study. The proportion of men to women about 1. 10: 1. Admission condition is critical for about 10.12% of the total and more concentrated in the cardiovascular department. Hospital stay ranged from 8 to 14 d. Inpatients with medical insurance is 62.93%. Total hospitalization cost distribution most is the 5 000-10 000 RMB. Hypertension complicated with coronary heart disease, blood lipoprotein disorder disease; phlegm and blood stasis and Yin deficiency of liver and kidney are the most in TCM syndrome type. Promoting blood circulation and removing blood stasis is the major in Chinese medicine treatment. Western medicine treatment basically conforms to the guidelines. The most antihypertensive drugs is calcium antagonistst, accounting for about 81.2% of the total number. Class ACEI, class ARB, beta blockers, diuretics class are accounted for 43.0%, 43.4%, 42.4%, 42.4%, fixed compound is only 2 393, accounting for about 8%. the total frequency of five classes of antihypertensive drugs is 78 206 times. The principal conclusions of this analysis are as follows: the elderly people is the most in hypertension, more men than women; medical insurance is the majority type in hospitalization cost; nearly half of the population is combined with coronary heart disease; phlegm and blood stasis and yin deficiency of liver and kidney are the most in TCM syndrome type; western medicine treatment basically conforms to the guidelines. Combination therapy is more, less fixed compound preparation in western medicine. Chinese medicine is mainly to promoting blood circulation. Suggesting that the clinical treatment in strict blood pressure and at the same time, pay attention to combination therapy and the use of fixed compound preparation,it's useful to control the blood pressure better. Combined with traditional Chinese medicine and resolving phlegm and removing blood stasis, reduce the target organ damage, reduce complications, the prevention and control work of hypertension in China still faces enormous challenges at present. The result provides reference information for clinical medicine and medical research.
