Objective To analyze the risk factors for drug-induced hypoglycemia in elderly diabetic patients,and to provide the basis for clinical prevention and treatment.Methods 78 cases with drug-induced hypoglycemia in elderly diabetic patients (observation group) and 256 elderly diabetic patients without drug-induced hypoglycemia(control group) were included,and the relative factors for drug-induced hypoglycemia were analyzed between the two groups.Results The stable rate of patient's condition was lower in observation group than in control group [38.5％ (30/78) vs.52.7％(135/256),x2 =4.872,P＜0.05].There were 9 cases (11.5％)、with alimentary control,28 cases (35.9％) treated with insulin and 41 cases (52.6％) treated with sulfonamide in observation group,and 89 cases (35.9％) with alimentary control,89 cases (34.8％) treated with insulin and 78 cases (30.4％) treated with sulfonamide in control group.The alimentary control was lower in observation group than in control group(x2 =15.557,P＜0.001).There was no difference in successful rate of insulin treatment between the two groups(x2 =0.034,P＞0.05).The successful rate of sulfonamide treatment was higher in observation group than in control group(x2 =12.726,P＜ 0.001).The age was older in observation group than in control group(t=2.494,P＜0.01).The body mass indexes and glycosylated hemoglobin level were lower in observation group than in control group(t=4.334 and 7.251,both P＜0.001).There were no differences in fasting blood-glucose and serum creatinine levels between the two groups(t=1.010 and 0.297,both P＞0.05).The course of diabetes was longer in observation group than in control group(t=2.579,P＜0.01).Conclusions The relative factors for drug-induced hypoglycemia in elderly diabetic patients include older age,longer course of diabetes,lower body mass index,lower fasting blood-glucose level,poorer glycemic control and higher dose of sulfonamide treatment.

OBJECTIVE To know the incidence, etiology, risk factors of hospital-acquired pneumonia(HAP). METHODS From Jan 2003 to Dec 2004, 129 cases of HAP were retrospectively studied. Epidemiologic data, etiology , and evolution of pneumonia were recorded. RESULTS The 115 patients with HAP had one or more intrinsic risk factors, mainly malnutrition (albumin values

This article reveals the present state of teaching staff in teaching hospitals and difficulties and obstacles the hospitals confront when conducting the clinical courses through the investigation and analysis of 6 teaching hospitals.It provides a very useful reference for teaching hospitals in term of expanding their teaching resources and carrying out staff training.

The university students must promote themselves to become persons with sound personality in order to adapt to the society request for talents.But the university students experience emotion burnout and the deviation of development in mental and behavior during the period full of variety and surging.So the education of sound personality should be placed in the higher education to raise the university student's comprehensive character.

Objective To clarify the effect of esophageal valve forming esophageal and gastric sleeve joint surgery for preven‐ting postoperative anastomotic complications of esophageal cancer .Methods A randomized controlled trial was designed to incorpo‐rate a total of 394 patients with esophageal cancer from January 2010 to June 2013 .This study has been registered in the Chinese clinical trial center and received a registration number :ChiCTR‐TRC‐13003817 .Among them ,9 cases (2 .3% ) were excluded be‐cause of the non line esophageal cancer radical operation .The remaining patients were randomly divided into two groups ,191 cases in group A and 194 cases in group B ,according to the principle of random grouping .Group A was experimental group ,patients ac‐cepted esophageal valve forming esophageal and gastric sleeve joint surgery ,and group B was the control group ,patients received conventional anastomosis .Results The incidence of anastomotic leakage after operation in group A and group B were 4 .1% and 3 .6% ,thse results were not statistically significant (P=0 .768) .In the observation of anastomotic stenosis ,7 patients died after sur‐gery .In the remaining cases ,there were 13 cases (6 .9% ) and 25 cases (13 .2% ) in group A and group B ,respectively ,the differ‐ence was statistically significant (P=0 .044) .Furthermore ,reflux oesophagitis and Barrett′s epithelium were found in 105 patients (55 .3% ) in group B ,and 54 (28 .7% ) patients in group A ,the difference was statistically significant (P<0 .01) .Conclusion E‐sophageal valve forming esophageal and gastric sleeve joint surgery can effectively prevent postoperative gastroesophageal reflux , but also can reduce the postoperative incidence of anastomotic stenosis .

Objective To investigate the effect and changes of IL -18 and IL -35 in patients with recurrent Hp positive gastric ulcer by treating with leibeirazole quadruple therapy.Methods 180 patients with recurrent Hp positive gastric ulcer were divided into two groups.The control group(90 cases)was applied amoxicillin,clarithromy-cin and colloidal bismuth pectin.The observation group was added leibeirazole.The effect and changes of IL -18 and IL -35 were observed before and after treatment in the two groups.Results The effective rate (86.67% vs. 73.33%,χ2 =5.000,P =0.025),inflammatory reaction rate(26.67% vs.51.11%,χ2 =11.314,P =0.008)and Hp positive rate(16.67 % vs.31.11%,χ2 =5.163,P =0.023)were higher in the observation group than in the control group.Expression of IL -18 was decreased after treatment[(70.80 ±11.21)ng/L vs.(88.83 ±7.13)ng/L, t =8.27,P =0.0210]in the observation group,but no change in the control group[(85.62 ±10.84)ng/L vs. (87.64 ±9.28)ng/L,t =0.78,P =0.4512).Expression of IL -35 didn't change after treatment in the two group (P >0.05).Conclusion Leibeirazole quadruple can increase the clinical effect,decrease the expression of IL -18 in patients with recurrent Hp positive gastric ulcer,it is worthy to be applied in clinical treatment.

Objective To investigate the potential role of asiaticoside in controlling the capsular formation around breast implant in rats. Methods Forty female Sprague-Dawley rats were implanted with 2 silicone elastomer in bilateral dorsal interscapular region subcutaneously each, and randomly assigned to 2 groups (n=20 in each group): control group and experimental group. The experimental group was of intragastric administration with asiaticoside (24 mg/kg) daily while control group with saline of identical volume. On day 7, 14, 28, 56 and 84, 4 rats from each group were sacrificed. Specimens were collected for HE staining. Image-pro Plus was applied to measure the thickness of capsule at different time intervals and the dynamic alteration in histology was observed. Results In experimental group, the formation of capsule ended up with a thickness of (194.33?23.27)?m, dramatically thinner than that of control group (306.08?31.31)?m (P

Aim To study the effect of paeonol on proliferation of vascular smooth muscle cell in atherosclerosis rabbits.Methods Atherosclerosis model on rabbits was established by high fat diet.The pathologic changes of aortic blood vessel were observed by lightmicroscope.The effect of paeonol on the proliferation of vascular smooth muscle cell in vitro was analyzed by MTT method.The lipid,SOD and MDA contents in aorta tissue were assayed by employing the automatic biochemistry analyzer and enzymic method respectively.IL-1?,TNF-? were quantified by radio immunoassay.The expresstion of PCNA protein was assayed by immunohistochemical method.Results Treated with Paeonol(75,150 mg?kg~(-1)) by interagastric administration for 6 weeks,the thickness of vascular tunica intima was observed and the number of foam cells was decreased in atherosclerosis rabbits.Paeonol(100～300 mg?L~(-1)) could inhibit the proliferation of cultured vascular smooth muscle cell and diminish the level of TC,MDA,pro-inflammatory cytokines,as well as enhanc the concentration of SOD in aortic tissue of atherosclerosis rabbits.The expressing intensity of PCNA protein was weakened.Conclusion Paeonol could inhibit the proliferation of vascular smooth muscle cell in vivo and in vitro,which may be related to decrease of contents of lipid,the extent of lipid peroxidation and the concentrations of proinflammatory cytokines.Paeonol might regulate the proliferation periods of vascular smooth muscle cell through inhibiting the expression of PCNA protein.
