To investigate the effect of arginine vasopression (AVP) on the secretion of vascular endothelial growth factor (VEGF) by vascular endothelial cell (VEC). VEC of human greater omentum artery were isolated and cultured. The concentrations of VEGF and activity of protein kinase C (PKC) in the culture medium were measured. Results indicated that after the cells were incubated with 1?10 -9～1?10 -7mol/L AVP for 6 hours, the concentration of VEGF and activity of PKC were markedly increased compared to control (P

AIM: To investigate the regulation of ‘Tiao Gan Fang Yao’(TGFY) on neuroendocrine-immuno-function of bandage-stressed rat . METHODS:The stressed rat model was made by bandage. RIA was adopted to measure the function of hypothalamus-pitutary-adrenal gland axis (HPAA) of stressed rat. Meanwhile, the immunity of stressed rat and the regulation of TGFY were observed.RESULTS:Bandage stress increased the contents of serum corticosterone(CORT), and ACTH, and hypothalamus corticotropin releasing hormone ( P

A total of 3 431 subjects aged 18 years or over from Liaoning province were involved in this study.The prevalence of metabolic syndrome(MS) was 19.50%,being 19.79% in men and 18.44% in women, according to the standard of Chinese Diabetes Society in 2004.Villages had the highest prevalence of MS in women,while cities had the lowest;towns had the highest prevalence of MS in men,while villages had the lowest.The prevalence of MS was increased with both aging and income.The peak of MS is turning to the developing district.

Objective To analyze whether there are any gender differences in clinical features of acute type 1 diabetes mellitus.Methods Clinical data of 193 patients with acute type 1 diabetes mellitus were collected in our hospital from 2002 to 2007,and subjected to statistical analysis by SPSS.Results The ratio of male to female in all the subjects was 1.6:1.There was no significant gender difference in such clinical aspects as age,fasting blood glucose level,HbAlc concentration,positive percentage of serum autoantibodies against pancreatic islet or morbidity of diabetic neuropathy.In contrast to the males,the onset age was significantly younger,the diabetic duration longer,fasting serum C peptide level lower and the incidence of ketotic acidosis higher in female patients.The patients with onset age less than 14 years (puberty) did not show any significant gender differences in the above-mentioned clinical aspects.Among those with onset age more than 14 years,the females had significantly longer duration and lower fasting serum C peptide level than males.The male patients with onset age more than 14 years had significantly higher fasting serum C peptide level than those less than 14,whereas it was the same for total positive percentages of pancreatic islet autoantibodies and morbidity of diabetic neuropathy in females.Conclusion Gender differences may exist in some clinical features of type 1 diabetic patients with acute onset after puberty, which may partially result from the effects of sex hormones.

Objective To study the relationship between the number of outpatient complaints and the time or the outpatient amounts.Methods A retrospective analysis of 1289 cases of outpatients' medical complaints with basic records since 2009 in our hospital was carried out.The time regularity of the number of outpatient complaints,or the complaint rate was analyzed.And the correlation between the outpatient amounts and the number of outpatient complaints,or the complaint rate was also analyzed.Results In our hospital,the mean monthly number of outpatient complaints was (23.44±8.41)cases; the mean monthly outpatient account was (246 000±27 417)cases.The differences among monthly outpatient complaints,outpatient accounts and monthly complaints rate among every years were statistically significant.Within one year,the outpatient complaints numbers were lowest in February and January.And the outpatient complaints rate was low in November,January,February and December.There were statistically significant correlation between the monthly outpatient complaints and monthly outpatient accounts,and between the monthly outpatient complaints rate and monthly outpatient accounts.Conclusions There was time regularity in the outpatient complaints rates in one year.And there was certain correlation between the outpatient complaints rate and the outpatients' accounts.

Zixue san is a preparation in Chinese Pharmacopoeia ，and is a commonly used representative formula in Liangkai formulation. In the previous editions of Chinese Pharmacopoeia ，for the item of the formulation and preparation method of Zixue san，“mirabilite”“mirabilite（prepare）”“Xuanming powder ”and other different descriptions have been repeatedly modified and amended；the methods of preparation of mirabilite in the processing specifications of different provinces and cities are also different，causing effects in actual production. Therefore ，the author has researched the historical evolution of Zixue ，the formulation and preparation method of Zixue san in the previous editions of Chinese P harmacopoeia，and has expounded the change process of mirabilite，mirabilite（prepare），Xuanming powder in the item of formulation and preparation method of Zixue san. In addition ，the author compares Chinese Pharmacopoeia with the processing methods of mirabilite in the national and provincial processing specifications ，in order to provide a basis for the processing of mirabilite in the formulation of Zixue san.

Objective To explore the status of healthcare-associated infection(HAI)in hospitals in Buyi autono-mous prefecture of Guizhou Povince,and provide basis for formulating HAI control measures.Methods A survey was conducted by combined methods of bed-side survey and medical record reviewing,prevalence rates of secondary and above hospitals in Buyi autonomous prefecture in Guizhou Province between September 10 and October 5,2014 were surveyed.Results 6 577 hospitalized patients should be investigated,6 541(99.45%)were actually investiga-ted.The prevalence rate and case prevalence rate of HAI were 1 .83% (n=120)and 1 .94%(n=127)respectively. The top three departments of HAI distribution were intensive care unit (26.32%),neurosurgery (6.10%),and neonatal intensive care unit(5.13%);the main infection site was lower respiratory tract(n=39,30.71 %),followed by skin-soft tissue (n=24,18.90%)and superficial incision (n=23,18.11 %).58 pathogenic isolates were detec-ted,gram-negative bacteria were the major pathogens (n=44),gram-positive bacteria and fungi were 10 and 3 iso-lates respectively.Antimicrobial usage rate at survey day was 42.12%,64.75% of which were for therapeutic, 26.83% for prophylactic,and 8.42% for therapeutic+prophylactic use;the percentage of mono-drug,two drugs combination,and three or more drugs combination use were 79.53%,19.89%,and 0.58% respectively;bacterial detection rate in patients receiving therapeutic as well as therapeutic+prophylactic antimicrobial use was 13.76%. Conclusion Survey on prevalence of HAI is helpful for understanding the current status of HAI,monitoring on HAI in key departments of hospital and key sites of patients should be strengthened to reduce the occurrence HAI effectively.
