Lower extremity deep venous thrombosis (LEDVT) is one of the common complications for postoperative patients with gynecologic oncology,which affect the prognosis of surgical patients seriously.LEDVT mainly caused by vein wall damage of pelvic surgical procedures and lower extremity infusion,slow venous blood flowing leading by anesthesia and bedridden,the hypercoagulability due to fasting before and after surgery and lack of fluid amount.

Objective To investigate the role of ERK1/2 signal pathway in the apoptosis of rat mesangial cells inhibited by TIMP-1.Methods The human TIMP-1 sense and antisense plasmid were transferred into rat mesangial cells through liposome,while mesangial cells transfected with pcDNA3 and non-transfected mesangial cells were used as control.After being stimulated with high glucose(HG 25mmol/L D-glucose)and PD98059(50 ?mol/L)for 24 hours,the apoptosis rate was measured by flow cytometry.The expression of ERK1mRNA was assayed by RT-PCR.The protein expression of p-ERK1/2 in the cell was analyed by ELISA.Results(1)The apoptosis rates of the non-transfected group,transfect pcDNA3 group,sense group and antisense group in the culture medium of high glucose withact PD98059,were(12.10?2.21)%,(11.90?3.34)%,(5.50?0.50)%and(20.70?3.41)%,respectively.The apoptosis rate of the sense group was significantly lower than that without transfection(P

0.05),but significantly lower than control group when run-out L-CN(P

Objective: To investigate the structural characteristics and the primary functions of antigen gene cC1. Meth-ods: The primary and the secondary structures were analyzed using bioinformatics programs provided by Internet servers.The predicted 3D structure of cC1 was established by homology protein modeling method. Anticoagulant activity of GST-anx32 was assayed by modified kaolin partial thromboplastin time (KPTT). Results: cC1 had high homology to annexinsgenes both at nucleic acid and at amino acid level. It contained 4 homologous regions, and each region included the typical an-nexin motif "G-X-G-T (38 residues)-D/E". The results of KPTT assay showed that the recombinant protein GST-anx32 hadhigh anticoagulant activity. Conclusion: cC1 has the common structures of annexins but the homology to the extant annexinsis no more than 48%, cC1 is a member of a novel annexin subfamily and designed as annexin32.

Objective:To assess coronary stenosis using 256-slice spiral CT (CTA).Methods:The data of 126 pa-tients diagnosed as coronary heart disease (CHD)using CTA and coronary angiography (CAG)Were retrospectively analyzed.The CAG results for CHD Were regarded as “gold standard”diagnosing CHD.The CTA diagnostic value for CHD and consistency of CAG and CTA diagnosing coronary stenosis Were analyzed.Results:A total of 393 cor-onary segments Were assessed using CTA.According to CAG results for CHD ,the CTA diagnostic accuracy Was 89.3%,sensitivity Was 91.4%,specificity Was 84.8%,negative predictive value Was 82.2% and positive predictive value Was 92.8%;the consistency of CAG and CTA diagnosing coronary stenosis Was good (Kappa value =0.755, P<0.01).Conclusion:The 256-slice spiral CT can diagnosing coronary stenosis,it possesses high sensitivity in di-agnosing vascular stenosis;as a simple and noninvasive examination it can be used as a reliable method for early screening subhealthy population and reexamine of putients With coronary heart disease.

AIM: To determine whether chronic hypercholesterolemia affects ionic currents on cardiac ventricular myocytes of rats. METHODS: Whole - cell patch - clamp technique was used to record the ionic currents in single cardiac myocytes isolated from normal cholesterolemia and hypercholesterolemia rats. RESULTS: In the hypercholesterol group (group Ⅱ ), serum total - cholesterol level was significantly higher than that of normal group (group Ⅰ) [ (3. 10 ±tricular myocytes of rats, 50% repolarization of action potential duration (APD50) prolonged from (70. 86 ± 8.12) ms (group Ⅰ) to (116.16±6.90)ms (group Ⅱ) (n=10 in each group, P＜0.01); APD90 prolonged from (95.10±7. 27)ms (group Ⅰ ) to (144. 04 ± 7.39)ms (group Ⅱ ) (n = 10 in each group, P ＜ 0. 01 ); at the test potential of - 120 mV, Ik1 increased from ( - 16. 98 ±4. 54) pA/pF(group Ⅰ ) to ( - 19.92 ±4.08) pA/pF (group Ⅱ ) (n = 12 in each group, P ＜ 0. 05 ); at the test potential of 0 mV, ICa- L decreased from ( - 8.56 ± 1.29) pA/pF ( group Ⅰ ) to ( -5. 24 ± 0. 90) pA/pF ( group Ⅱ ) ( n = 10 in each group, P ＜ 0. 01 ); at the test potential of + 60 mV, Ito decreased from (13.20±1.97) pA/pF (group Ⅰ) to (10.30±1.97) pA/pF (group Ⅱ) (n=8 in each group, P＜0. 05). CON-CLUSION: Hypercholesterolemia affects the ionic currents on cardiomyocytes of rats greatly, which may be the ionic mechanism of cardiac toxicity induced by hypercholesterolemia.

Objective To analyze the factors influencing augmentation index (AI) by examining the AI changes in patients who received continuous ambulatory peritoneal dialysis (CAPD) therapy, and evaluate the artery elastic function situation. Methods The height, weight, blood pressure, blood indicators were detected in 46 CAPD patients (CAPD group) and 42 controls (control group). AI was managed by OMRON HEM-90OOAI, and the influencing factor was analyzed. Results Systolic blood pressure(SBP),diastolic blood pressure(DBP), pulse pressure, central aortic pressure and AIp75 (AI value, when pulse was 75 beats/min) in CAPD group were significantly higher than those in control group. Within CAPD patients,the AIp75, in female was significantly higher than that in nude [(96.67±8.95 )% vs (89.89±6.46)% ,P =0.022]. Simple correlation showed positive relationship in gender, age, SBP, DBP, pulse pressure and central aortic pressure with AI; and negative relationship in height, weight and weight index with AI; while there was no relationship between AI and all kinds of chemical examination indicators or dialysis years.Multiple linear regression analysis evidenced that gender,age, height, DBP and central aortic pressure of CAPD patients had linear regression relation with AI. Conclusions It indicates a decreased artery elasticity and an increased stiffness occurs in CAPD patients. AI has tight correlation with age, height, DBP and central aortic pressure, and is an non-invasive factor thai partially reflects the arterial elasticity. Central aortic pressure is relevant with aortic elasticity and rigidity closely. Measuring central aortic pressure is very imporrant for preventing cardiovascular accident.

OBJECTIVE To find out fulminate epidemiological features of Stenotrophomonas maltophilia in ICU and the ways to prevent and treat this nosocomial infection.METHODS The case histories from 4 inpatients who developed S.maltophilia infection in the same ward from Feb 5 to 16,2006,were studied retrospectively to find out the reasons of its onset and its treatment based on the sputum culture results.RESULTS The fulminate S.maltophilia was found from the rail of the patient bed,the connection part of water container of 2 respiratory machines of exhalation valve assembly and the liquid of ultrasonic aeriation machine.CONCLUSIONS The infection is a localized one.The main reasons of the infection are unthorough disinfection of respiratory machine and the contamination of medical treatment environment.Whenever the infection is found in the ward,the thorough disinfection needs immediately,and no new patient admitted.

Objective To investigate the value of the cold supernatant in the clinical practice. Methods 25 cases of TTP got a direct infusion of cold supernatant or plasma exchange using cold supernatant as fluid replacement and with medications at the same time. Then we observed the clinical treatment effect of all the cases. Results The clinical remission rate of 25 cases of TTP was 80%. Conclusion The cold supernatant could be used as a new blood component in clinical application,especially for the treatment of thrombotic microangiopathy (TMA). It not only can save valuable blood resources,but also can reduce the economic costs of patients.
