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 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

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 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.

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.

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.

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 To provide the utilization information of drugs in Chongqing ,which has been analyzed the statistical data from 18 Chongqing medical organizations'sales volume from 2005 to 2007. Methods We have investigated and graded the sum of the drug purchasing money,the significant medical varieties,and the pharmaceutical manufactories to analyze the latest situation during this three years. Results According to the analysis,the sales number was increasing at a rate of about 20% per year. Water,heat and balance of electrolyte were the most positive rate increased (106.85%). However,the vitamin sell was the negative one dropping down at the rate of 10.47%. In addition,there was only three pharmaceutical companies in Chongqing ranked top 100. Conclusion To predict the future of the drug purchasing money will still rise successively. Nevertheless,it is influenced by rectifying the domestic medicine market so that Chongqing pharmaceutical enterprises are developing slowly without new varieties of drugs being produced.

Objective To investigate the influence of a combination of Chinese herbs,Astragalus membranaceus var.mongholicus and A ngelica sinensis (A&A)on the production and elimination of reactive oxygen species (ROS)and the underlying mechanism during the process of renal interstitial fibrosis in the obstructive kidneys of rats with unilateral ureteral obstruction(uuo).Method Male Wistar rats were randomly divided into control,sham,UUO and UAA (UUO+A&A)groups.The rats in UAA group were administered with A&A(14 g/kg)by oral gavage once daily:the ones in sham and UUO group were given with equal volumes of water.Three days after setting up models,pathological injury of renal tissue was evaluated.Level of total antioxidant capacity(T-AOC)and activity of CuZn superoxide dismutase(CuZn-SOD)in renal homogenates were measured bv spectrophotometry.Expression of NADPH oxidase subunits p47-phox,p22-phox and nintrotyrosine was analyzed by Western blot. Results Severe interstitial inflammatory cells infiltration, mild tubular atrophy and interstitial fibrosis were found in UUO group, which were alleviated by A&A administration. Compared to sham group, T-AOC of UUO group was not significantly changed, but the expression of the nitrotyrosine, NADPH oxidase subunits p47-phox and p22-phox was increased significantly (P<0.05). After A&A administration, T-AOC level was increased (2.5±1.1 vs 1.5±0.5, P<0.05) and the expression of nitrotyrosine was decreased (P< 0.05) in UAA group compared with UUO group. Additionally, the expression of p47-phox was reduced at day 3 (P<0.05), accompanied with a reduced expression of p22-phox (P< 0.05). CuZn-SOD activity was not significantly changed among the groups. Conclusion The inhibition of A&A in NADPH oxidase subunits p47-phox and p22-phox, which is responsible for reduction of oxidative stress, is associated with the alleviation of renal fibrosis in obstructive rat kidney.
