OBJECTIVE To discuss the hospital infection management in infectious disease ward,to improve the ward quality of hospital infection,and to prevent and control infection inside hospital.METHODS By the plan,do,check and action(PDCA) circle method to collect information,analyze cause,establish plans,and organize to put into practice and check management.RESULTS Making the control quality of hospital infection improved obviously,various index signs attain the Hospital infection management norm and The disinfection technique norm issued by Ministry of Health and infection managment standard requirement for third class grade A hospitals.CONCLUSIONS Inducting PDCA circle method and step by step to insist on it is a good method to improve the control quality of hospital infection.

OBJECTIVE:To investigate the inhibitory effect of ligustrazine on the formation of macrophage-derived foam cells and its possible mechanism. METHODS:Human acute mononuclear cells (THP-1) were incubated with 160 nmol/L phorbol ester (PMA) for 24 h to differentiate into macrophages;and the macrophages were incubated with oxidized low-density lipoprotein (ox-LDL)culture solution containing 80 mg/L for 24 h to differentiate into macrophage-derived foam cells. And then the cells were randomly divided into blank control group(ox-LDL),model(AngⅡ)group,positive control(valsartan)group,and ligustrazine low,medium and high concentration groups(the mass concentration were 0.025,0.05 and 0.1 g/L). After all cells were respective-ly incubated with 80 mg/L ox-LDL culture solution for 48 h,oil red O staining was adopted to observe the transformation rate of foam cells,enzyme chemical method was used to determine the content of cholesterol,and real-time quantitative polymerase chain (RT-PCR)and Western blot were conducted to detect expression levels of Acyl-coenzyme A cholesterol acyltransferase-1(ACAT-1) mRNA and its protein. RESULTS:Compared with blank control group,the transformation rate of foam cells and content of choles-terol in model group were increased,and the expression levels of ACAT-1 mRNA and its protein were obviously strengthened,with significant differences(P<0.01 or P<0.05). Compared with model group,the transformation rate of foam cells and content of cho-lesterol in positive control group(valsartan)and ligustrazine low,medium and high concentration groups were decreased,and the expression levels of ACAT-1 mRNA and its protein were obviously weakened,with significant differences (P<0.01 or P<0.05). CONCLUSIONS:Ligustrazine can inhibit the macrophages differentiating into foam cells,by a mechanism that may be related to inhibiting expression of ACAT-1,and reducing content of cholesterol to reduce formation of foam cells.

OBJECTIVE:To prepare rapid-disintegrating oral tablets of indometacin and establish a method for its quality control.METHODS:The formula of the oral tablets was optimized by orthogonal test with the formula quality of CMS-Na(A),L-HPC(B),MCC(C),manniton(D) as factors,and the disintegrating time as index.The content of indometacin was determined by ultraviolet spectrophotometry.RESULTS:The optimal formula of the tablets was the following,A∶B∶C∶D=5∶5∶50∶5.The preparation was white in color and its quality was up to the related standard specified in Chinese Pharmacopeia (2005 edition) in identification.The linear range of indometacin was 2.08～41.6 ?g?mL-1 (r=0.999 9).The average recovery was 99.3%.The intra-day RSD=0.53% and inter-day RSD=0.74%.CONCLUSION:The preparation is simple and feasible in preparation process,and controllable in quality.

Objective To explore the application effect and safety of ultrasonic location in interscalene bra-chial plexus block anesthesia.Methods 100 cases with upper extremity orthopedic surgery patients were selected, according to the brachial plexus between the different positioning methods,they were divided into control group and observation group,50 cases in each group,the control group chose the traditional anatomical localization techniques, observation group interscalene under ultrasound guidance brachial plexus block,two groups of anesthesia were com-pared,block success rates and complications were observed.Results The block operation time,anesthesia onset time,duration of analgesia and anesthesia drug dosage of the observation group were (185.5 ±24.86)s,(11.55 ± 2.89)min,(11.42 ±2.39)min,(17.25 ±2.54)mL while the control group were (228.75 ±26.20)s,(16.05 ±4.66)min,(10.95 ±2.83)min,(19.50 ±2.79)mL,there was significant difference between two groups(t =18.34, 10.28,9.72,10.68,all P <0.05).the anesthesia success rate of the observation group was 98%,significantly higher than 88% of the control group,the difference between the two groups was statistically significant(χ2 =9.12,P <0.05).The incidence rate of complications in the observation group was 0,while the control group was 8%,two groups had significant difference in complication rate(χ2 =8.34,P <0.05).Conclusion Ultrasonic location in in-terscalene brachial plexus block anesthesia has a good clinical effect,with high safety,which is worthy of populariza-tion and application.

Adiponectin is a kind of adipocyte-specific protein which is only inversely related with obesity by now. It is involved in enhancing insulin sensitivity,anti-atherogenic and antiinflammatory activities.Recent studies have reported that adiponectin is closely correlated with the genesis and development of a variety of obesity related malignant tumors,especially postmenopausal breast cancer.Obesity is an independent risk factor for the development of breast cancer.Recently researches about the correlation between adiponectin and breast cancer relations and the action mechanisms,signaling pathways have made a progress.
