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 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 evaluate the effect of early aspirin combined with low molecular weight heparin calcium in prevention of portal system thrombosis after portaazygous disconnection in patients of portal hypertension.Methods In this study.90 cases with cirrhotic portal hypertension were divided randomly into two groups(control group:44 cases,observation group:46 cases),after standard splenectomy and pericardial devascularization.On the day when abdominal and gastrointestinal drain was not bloody(at 2-5d,mean 3d after operation),low molecular weight heparin calcium 4100 IU per day was given to observation group by subcutaneous injection for 10 days.During treatment,blood platelet(PLT)count was monitored.When PLT in both groups>300 ×10~9/L.low molecular dextran 500 ml per day was given by iv drip for 7-14 days,oral enteric aspirin 100 ms/day was given,until PLT reached normal range.Portal venous thrombosis was evaluated by color Doppler ultrasonography weekly for 3 weeks.Results Postoperative incidence of portal vein thrombosis in observation group(7%)was lower significantly than that in control group(27%)(X~2=6.972,P<0.05).Incidence of postoperative complications in observation group(7%)were lower significantly than that in control group(32%)(X~2=9.393,P<0.01).Mortality rate in observation group(2%)were lower significantly than that of control group(18%)(X~2=4.748.P<0.05).There was no significant difference between the two groups in blood platelet count during observation(P>0.05).Prothrombin time,active pact thromboplastin time were also similar in the two groups(P>0.05).Side effect such as self-limited subcutaneous hemorrhage developed in no cases in control group compared to two cases in observation group(X~2=0.558,P>0.05).Conclusion It is a safe and effective method to use early aspirin combined with low molecular weight heparin in the prevention of portal system thrombosis after splenectomy and portaazygous devascularization in cirrhotic portal hypertensive patients.

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.

Objective To probe into the methods of postoperative nursing care for the patient undergoing domino liver transplantation.Methods The key of postoperative care included:monitoring of vital signs,the condition of cruor and the state of drainage rigorously; keeping the balance of intake and output; taking the immunosuppressive drugs correctly; proper diet; prevention of complication;giving psychological nursing.Results The patients passed the perioperative period successfully and were all cured.Conclusions To aim at the characteristic of this operation,implement holistic nursing care,is an important link to assure the patients of domino liver transplantation to recover smoothly after the operation.

Objective To investigate the incidence and the risk factors of the vascular disease in lower limbs of patients with type 2 diabetes(T2DM).Methods To retrospectively analyze 318 cases with T2DM patients.All the patients were checked on both lower limbs by color ultrasonic Doppler.The differences of ordinary and biochemical indicators between PVD group and non-PVD group were compared.Results There were 67.2％ (205/318) patients who had vascular disease in lower limbs with type 2 diabetes.Age,course of disease,HbAlC,TC,TG,SBP,DBP and BMI in PVD group were significantly higher than those in non-PVD group( P ＜ 0.01 ).Conclusion There was higher incidence of the vascular disease in lower limbs of patients with type 2 diabetes.And the independent risk factors were hypertension,hyperglycemia,hyperlipemia.It could help to prevent the development of lower limb blood vessel pathological changes in DM patients by controlling the levels of blood pressure,lipid and blood sugar strictly.

Objective To determine the risk factors for the development of systemic inflammatory response syndrome (SIRS) in the patients after cardiopulmonary bypass has been constructed. Methods Eighty three NYHAⅠor Ⅱ patients, aged 6month-66yr, weighting 7～97 kg, undergoing cardiopulmonary bypass, were enrolled in this study. SIRS score was performed during 24 h after the surgery. The patients were divided into 2 groups: SIRS group(S, SIRS score≥2) and non-SIRS group(U, SIRS score＜2). The risk factors were identified by logistic regression analysis. Results The incidence of SIRS was 83.13% . Logistic analysis indicated that arterial oxygen pressure (PaO2), retention time, and postoperative heart rate were closely related with the development of SIRS in patients on ICU after cardiopulmonary bypass (OR＝0.518,4.334,3.607,P＜0.05). Conclusions The arterial oxygen pressure (PaO2), ICU stay, and heart rate after cardiopulmonary bypass has been constructed can be served as the risk factors for the development of SIRS in patients.
