Objective To investigate the value of cluster cate forpatients with ventilator-associated pneumo-nia (VAP) in the intensive care unit. Method Three hundred fifty-four consecutive patients with mechanical ven-tilation support in the Emergency Intensive Care Unit of Nanjing First Hospital from January 2006 to September 2007 were included in this study. The cluster care included elevating patient's head and chest to at least 30 de-grecs to the horizontal level, intensiving frequency of oral-pharyngeal nursing with thorough suction, washing hands, changing ventialtor tube at shorter regular interval, closely observing temperature, sputmn, WBC count, pu-turn, white blood cell count, chest X-ray examination and respiratory tract bacterial culture etc. Another 398 me-chanical ventilated patients with conventional care in the Hospital from January 2004 to November 2005 were taken as control. The t -test and X2 -test were used for analysis. Results The morbidity of VAP was significantly de-creased after cluster care(16.6 % vs. 24.6% P<0.01), the length of intensive care unit stay (LOS) was shorter in patients with cluster care than those in patients of control [(10.75±5.86) d vs. (14.26±9.40) d, P <0.05]. Conclusions Pneumonia associated with mechanical ventilation can be effectively reduced by the cluster care.

Objective To evaluate the prognostic significance of metastastic lymph node ratio in patients with gastric cancer. Methods Clinical data of 319 patients with gastric cancer who underwent radical gastrectomy with at least 15 lymph nodes dissected per patient were analyzed retrospectively. Patients were divided into 4 groups according to the TNM staging system (1997,5th edition): pN0 (no positive lymph node), pN1(with 1～6 metastatic lymph nodes), pN2 group (with 7～15 metastatic lymph nodes), and pN3 group (with more than 15 metastatic lymph nodes), or into 4 groups according to the lymph node metastatic ratio: rN0 group (without metastasis of lymph node), rN1 group (with a lymph node metastatic ratio of <30%), rN2 group (with a lymph node metastatic ratio of 30%～60%), and rN3 group ( with a lymph node metastatic ratio of >60%). Survival was determined by the Kaplan-Meier method and differences were assessed by the Log-rank test. Multivariate analysis was performed using the COX proportional hazard regression model in forward stepwise regression with SPSS 13.0. Results Kaplan-Meier survival analysis demonstrated that the metastatic lymph node ratio significantly influenced the postoperative survival time. According to the lymph node metastasis system 77 patients were in group 1, 109in group 2, 60 in group 3, and 73 in group 4. The 2-year survival rate was 84.4%,66.1%, 35.0%,and 15.1% respectively, 3-year survival rate was 80.5%,45.0%,15.0% and 5.5% respectively, and 4-year survival rate was 71.4%,33.0%,5.0% and 1.4% respectively. If cases with the same positive number of lymph node (pN) group were stratified futher by lymph node metastatic ratio, there were no significant differences in the 3-year survival rate among the new rN groups (P>0.05), but there was a great difference in the distribution of prognosis among different groups. COX proportional hazard regression model analysis showed that the metastatic lymph node ratio was an independent factor for poor prognosis. Lymph node metastatic ratio was closely related with the location, modality of the operation and infiltration depth. Conclusions The staging system based on metastatic lymph node ratio is more reliable than the system based on the number of metastatic lymph nodes in the prediction of the prognosis of gastric cancer.

The column: Lichrospher C18 (5 ?m,150 mm?4.6 mm),the mobile phase: methanl∶0.01 mol/L sodium acetale buffer (pH 4.8) (59 ∶41); the flow rate:1 ml/min, the detection wavelength: 225 nm. The test and reference formulations of glipizide were given to 20 healthy male volunteers. Results: The calibration curve was linear within the range of (25～1 000)?g/L, r =0.999 4. The minimum detection limit was 25 ?g/L. The mean recovery was 89.84%, CV of inter day and intra day were no more than 5%.After a single oral dose of 10 mg glipizide test or reference tablet, the main pharmacokinetic parameters AUC 0-15, AUC 0-∞, T max ,C max and t 1/2 were (3 502.78?635.82) , (3 214.23?590.46)?g/( L?h),(3 868.22?699.93), (3 593.94?638.60)?g/(L?h),(3.85?1.44), (3.76?1.13)h, (550.80?110.19), (531.15?148.42)?g/L,(3.57?1.11)h and (3.80?1.06)h ,respectively. The relative bioavailability F 0-15 ,F 0-∞ were (110.6?19.8)% and (108.8?17.9)%. Conclusions: No significant difference exists among the pharmacokinetic parameters for the experimental tablets and the reference. The two formulations were bioequivalent.

Objective To investigate the correlation between gene polymorphisms in IL-10 promoter region and the susceptibility and clinical phenotypes of HCV infection. Methods Two groups of subjects were studied. Group 1 included 85 treatment naive patients with chronic HCV infection, and group 2 included 75 healthy blood donors. Genotyping of IL-10 promoter-592 was performed by PCR-RFLP. Results No significant difference was found in IL-10 promoter-592 genotypes between the healthy individuals and HCV-infected patients. However, IL-10 promoter-592 genetype A/A appeared more frequently in patients with ALT≥80U/L than in those with ALT

Objective To study the effects of diazepam and sodium valproate infusion with CRRT in treatment of patients with tetramethylene disulfotetramine poisoning. Methods Diazepam and sodium valproate were continuously infused to patients by infusion pump. Meanwhile, CRRT was used to eliminate tetramethylene disulfotetramine. Results Convulsion was effectively controlled within one hour in 7 patients. After treatment with CRRT for 1 to 4 times, all patients recovered. Conclusion CRRT with diazepam and sodium valproate infusion were effective in patients with tetramethylene disulfotetramine poisoning.

Objective To investigate the effects of preconditioning with 3-nitropropionie acid on myocardial apoptosis induced by ischemia-reperfusion injury.Method Twenty-four rabbits were randomly divided into control group(group C,n=8),precondition group(group 3-NPA,n=8)and 5-HD group(group 5-HD,n=8).The group 5-HD was treated intravenously with 5 mg·kg-1 5-HD(ATP-sensitive potassium channels blocker),group C and group 3-NPA received normal saline instead of 5-HD.Ten minutes later,5-HD group and 3-NPA group were injected with 3-NPA(3 mg·kg-1)and the group C was injected with normal saline.Twenty-four hours later,the left anterior descending coronary artery was ligated for 30 min and then unclamped for 120 min to estabhsh ischemi-a-reperfitsion injury model.After reperfusion,the infarct sizes of ventricular myocardium,apoptotic myocardial cells and the expressions of Bcl-2 and Bax protein were measured.Results Infarct sizes and apoptotic myocardial cells in group 3-NPA were less than those in the others(P＜0.01).The expressions of Bcl-2 in group 3-NPA.in-creased as compared with group C(P＜0.05)and group 5-HD(P＜0.05),whereas the expressions of Bax in group 3-NPA decreased as compared with group C(P＜0.05)and group 5-HD(P＜0.05).Conclusions Preconditioning with 3-nitmpropionie acid reduces myocardial apoptosis induced by isehemia-reporfusion injury which is attributed to the opening of mitochondrial KATP channels.
