Objective To investigate the effects of tension free herniorrhaphy on endocrine functions of patients with inguinal hernia. Methods One hundred and twenty seven patients were randomly divided into tension free group( n =65) and conventional group ( n =62). The mean ages of tension free group and conventional group were(51.8?14) year and(48.4?12) year respectively. There were 52 indirect hernias and 13 direct hernias in tension free group. There were 51 indirect hernias and 11 direct hernias in conventional group. Bassini repair was used in conventional group. Peripheral blood samples were obtained preoperatively and 3 h, 24 h after operation for measuring the levels of cortisol, T3, TSH, insuline, C peptide and and glucose. The data were analysed through t test. Results The levels of cortisol, C peptide and glucose in conventional group were remarkably higher ( P

The therapeutic effects of intensive insulin therapy in treatment of traumatic shock combined with multiple organ dysfunction syndrome (MODS) were investigated. A total of 114 patients with traumatic shock combined with MODS were randomly divided into two groups: control group (n=56) treated with conventional therapy, and intensive insulin therapy group (n=58) treated with conventional therapy plus continuous insulin pumping to control the blood glucose level at range of 4.4-6.1 mmol/L. White blood cells (WBC) counts, prothrombin time (PT), serum creatinine (SCr), alanine aminotransferase (ALT), serum albumin and PaO(2) were measured before and at the day 1, 3, 5, 7 and 14 after treatment. The incidence of gastrointestinal dysfunction, the incidence of MODS, hospital stay and the mortality were also observed and compared. After intensive insulin therapy, the WBC counts, SCr, ALT and PT were significantly reduced (P<0.05), but the level of serum albumin was significantly increased (P<0.05) at the day 3, 5, 7 and 14. In the meantime, the PaO2 was significantly elevated at the day 3, 5 and 7 (P<0.01) after intensive insulin therapy. The incidence of gastrointestinal dysfunction, the incidence of MODS, the length of hospital stay and the mortality were markedly decreased (P<0.01). The results suggest early treatment with intensive insulin therapy is effective for traumatic shock combined with MODS and can decrease the length of hospital stay and the mortality.

BACKGROUND AND OBJECTIVEStudies of passive smoking exposure in China however are of particular interest, because of the high lung cancer rate in people who are mostly non-smokers. The aim of this study is to explore the relationship between passive smoking and lung cancer among non-smoking Chinese.

METHODSBy searching Medline, PubMed, CENTRAL (the Cochrane central register of controlled trials), CBM, CNKI and VIP, et al, we collected both domestic and overseas published documents between 1987 and 2007 on passive smoking and lung cancer among non-smoking Chinese. Random or fixed effect models were applied to conduct meta-analysis on the case control study results, and the combined odds ratio (OR) and the 95% confidence interval (CI) were calculated as well.

RESULTSSixteen documents were included into the combined analysis, which indicated that there was statistical significance between passive smoking and lung cancer (OR = 1.13, 95% CI: 1.05-1.21, P = 0.001). It was significant of lung cancer among non-smoking subjects associated with amount of tobacco passively smoked more than 20 cigarettes daily, with life period in adulthood passive smoking exposure, with gender female, and with exposure to workplace. The P value, OR and 95% CI were P = 0.0003, OR = 1.78, 95% CI: 1.30-2.43; P = 0.0001, OR = 1.50, 95% CI: 1.23-1.83; P = 0.000 7, OR = 1.50, 95% CI: 1.19-1.90; P < 0.0001, OR = 1.41, 95% CI: 1.19-1.66; respectively. And there was no significant difference between passive smoking and lung cancer with amount of tobacco passively smoked within 20 cigarettes daily, with life period in childhood passive smoking exposure, with gender male and with exposure to spouse and parents.

CONCLUSIONPassive smoking is an important risk factor of lung cancer among non-smoking Chinese, and for non-smoking women who expose to environment tobacco smoke in a long period of time have a close relationship with lung cancer risk.

Objective To study the preoperative ultrasonographic parameters and their relationship with age in symptomatic CAS patients with different curative effects of stenting.Methods Fiftyseven symptomatic CAS patients admitted to our hospital for stenting were divided into young age group (n=7),middle age group (n=25),old age group (n=25) according to their age,and into very good curative effect group (n=18),good curative effect group (n=33) and no curative effect group (n=6) according to their postoperative NIHSS score.The carotid ultrasonographic parameters in different groups were compared and analyzed within 3 days before operation.Results A significant difference was found in the ratio of UPT,maximal ER of plaques,PV of stenosis,PI,resistance index (RI),carotid artery stiffness index (SI),distensibility coefficient (Dc) and compliance coefficient (Cc) in different curative effect groups (P＜0.01).The carotid artery SI was significantly higher in old age group than in young age group and middle age group (P＜0.01).A linear regression equation was established between carotid stiffness and age (y=0.075x-1.537,R2 =0.448,F=44.727,P =0.000).Conclusion The ratio of UPT,maximal ER of plaques,PV of stenosis,PI,RI,carotid artery SI,Dc and Cc are different in patients with different curative effects of stenting,and a linear relationship is found between carotid artery SI and age of patients.
