Objective To evaluate the effect of probucol on endothelium-dependent vasodilatation(i,e.flow- mediated dilation,FMD) function of the old patients with isolated systolic hypertension.Methods In this single- blind study,a total of 64 old pariems with isolated systolic hypertension were randomized to receive conventional an- tihypertensive therapy and probucol (0.5g twice daily,group A,n=33) or receive conventional antihyperrensive therapy(group B,n=31) for 12 weeks.The levels of blood lipid were measured and vascular endothelial function was assessed in the brachial artery by high-resolution ultrasound technique in form of endothelium-dependent vasodi- latation before and after treatment.Results After 12-week treatment,the levels of TC,LDL-C and HDL-C in group A were significantly reduced compared with those before treatment(all P0.05).Flow-mediated dilatation parameters in both groups were obviously improved compared with those before treatment( P

Objective To evaluate the effect of optimizing surgerical patients’handover procedures using tracking methodology.Methods Two hundred patients hospitalized between July 2011 and May 2012 were assigned in the control group,in which their handover was conduced conventionally.Another 200 patients between April 2012 to February 2012 were assigned in the observation group,where their handover was done by tracking methodology.The two groups were compared in terms of incidence of adverse events at handover,time for handover and satisfaction of medical staff.Result Compared with the control group,the study group showed significantly lower incidence of adverse events,shorter surgical handover time and higher satisfaction degree of medical staff(P<0.05).Conclusion The tracking methodology can help to optimize handover procedures and quality control management, reduce the incidence of adverse events and improve working efficiency.

In order to study the role of prostaglandin E2(PGE_2)on the pathogenesis of candidal vaginitis,the effect of Candida albicans and histamine on the production of PGE_2 by peripheral blood mononuclear cells from patients with candidal vaginitis and normal controls,the effect of PGE2 on germ tube formation of Candida albicans,and the effect of PGE2 on Candida albicans adhering to vaginal ep- ithelial cells were observed.The results showed that:Candida albicans and histamine induced PGE2 synergistically,and the production of PGE2 increased markedly.PGE2 enhanced germ tube formation in Candida albicans,increased the number of Candida albicans adhering to the vaginal epithelial cells, and the pathogenicity of C.albicans.The above results indicate that PGE_2 plays a role in the pathogene- sis of candidal vaginitis.

Objective The aim of this study was to evaluate the efficacy and safety of combination therapy with low-dose pravastatin and fenofibrate in patients with combined hyperlipidemia. Methods One hundred eighty nine patients with combined hyperlipidemia were randomly assigned to receive 10 mg pravastatin (n=64) or 200 mg fenofibrate (n=63), or a combination of 10 mg pravastatin and 200 mg fenofibrate (n=62) for 12 weeks. The patients in the monotherapy groups (n=35) whose lipid levels were not controlled after 12 weeks were randomly assigned to receive 20 mg pravastatin, or 200 mg fenofibrate, or a combination of 10 mg pravastatin and 200 mg fenofibrate for another 12 weeks. Lipid levels and adverse effects were assessed. Results After 12 weeks treatments, serum TC, LDL-C and TG levels were reduced and HDL-C was increased more significantly in combination therapy group, compared with 2 monotherapy groups (all P

Objective To evaluate the long-term toxicity of endostatin injection to Beagle dogs,and to provide safety evidence for clinical experiments.Methods Twenty-four pure-blood Beagle dogs were assigned to four groups averagely with six dogs for each group,and the sex ratio was 1∶1.The animals in three of four groups received endostatin injection at low(1.6mg/kg),medium(6.3mg/kg)and high(25.0mg/kg)dosage,respectively,and the animals in the other group acted as control.The Beagle dogs were injected intravenously daily for up to 3 months with the exception of the dogs in control group.The indicators of ordinary toxic response,weight,electrocardiogram and hematology were collected,and the blood biochemical analysis,routine urinalysis and histopathologic examination were also performed.Results Only ordinary toxic responses such as anorexia and laxness were observed from l dog in high dose group,and simultaneously disappeared in 4 days.The weight of all Beagle dogs studied increased in a normal rate.No significant difference was found in each group of dogs on heart rate,electrocardiogram and indicators of urinalysis.No evident changes were observed in dogs on hematological and biochemical indexes.The pathological chances in different levels were observed in a dog's liver of low dosage group and a dog's kidneys of blank control group,but such changes were regarded as the spontaneous pathological changes,not related to the application of endostatin injection.Conclusion The non-toxic dose of endostatin injection on Beagle dogs was estimated to be 6.3 mg/kg under the present conditions.

Objective To study the heart rate variability(HRV) and blood pressure variability(BPV) in patients with different grades of hypertension.Methods 120 cases of patients with hypertension,according to 1999 WHO/ISH hypertension diagnostic criteria are:1 hypertension in 40 cases,2 of hypertension in 40 cases,3 of hypertension in 40 cases and 40 cases of normal control group were detected heart rate variability and blood pressure variability.Results HRV was significantly different between the two groups(P <0.05 or p <0.01).The blood pressure increased and HRV tended to decrease.The BPV was significantly different(P < 0.01) between the two groups;the blood pressure increased and the BPV tended to increase.Conclusion The grade of hypertension is related to HRV and BPV.

In most universities the usage of digital information resources are not ideal.One reason is that primary audience groups of libraries——college students rarely use these resources.So we propose some measures and proposals for university libraries to provide the service of digital information resources for university students.

Objective To explore effect of application of quality control circle (QCC)on improving the correct rate of hand hygiene (HH)among health care workers (HCWs)in intensive care unit(ICU).Methods QCC activity group was set up,the activity theme was established,correct rate of HH among HCWs in March 2014 (pre-inter-vention group)was monitored,the causes of incorrect HH behavior were analyzed,goals were set;from May 2014, QCC activities were initiated,correct rate of HH between before performing QCC activities and September 2014 (post-intervention group)was compared.Results 834 and 900 times of HH among HCWs were investigated before and after performing QCC activities,the number of correct HH before and after QCC activities were 360 and 714 re-spectively,correct rate of HH after implementing QCC was higher than before QCC activities (79.33% vs 43.17%,χ2 =240.19,P <0.05).The correct rate of HH among HCWs of this ICU and HCWs engaging in ad-vanced studies in this ICU after implementing QCC activities were both higher than before QCC activities (χ2 =264.44,6.36,respectively,both P <0.05).The main incorrect HH before and after QCC was non-implementation of HH indication.Conclusion Application of QCC activities for the management of HH among HCWs can effec-tively improve the correct rate of HH among HCWs in ICU.
