Objective To investigate the imaging features and preoperative staging value of ultrasonic endoscopy and gastrointestinal ultrasonic contrast in the gastric carcinoma examination.Methods One hundred and sixty eight patients with gastric carcinoma verified by operation and pathology in our hospital from October 2010 to October 2015 werecollected.Then their imageological data including ultrasonic endoscopy and gastrointestinal ultrasonic contrast examinations were retrospectively analyzed and compared with the postoperative pathological results.Results The accuracy rate of preoperative T staging in ultrasonic endoscopy was significantly higher than that of gastrointestinal ultrasonic contrast,the difference had statistical significance(P＜0.05);the accuracy rate of preoperative N/M staging in gastrointestinal ultrasonic contrast was s1gnificantly higher than that in ultrasonic endoscopy,the difference had statistical significance(P＜0.05).Conclusion Ultrsonic endoscopy and gastrointestinal ultrasonic contrast have different advantages and values in preoperative staging:ultrasonic endoscopy has higher accuracy rate in the diagnosis of primary gastric carcinoma;gastrointestinal ultrasonic contrast is better in diagnosing metastasis of gastric carcinoma,moreover which shows the consistency with postoperative pathological staging.

Objective To discuss the influence hand hygiene intervention on general ICU acquired methicillin-resistant staphylococcus aureus (MRSA) infection and its improvement. Methods Hand Hygiene Cognition Questionnaire that passed the reliability and validity test was used to compare the change of cognition on hand hygiene of medical staff. According to the results of the questionnaire, the intervention was carried out by continuous intensive training. The compliance with hand hygiene of medical staff was observed by monitoring equipment in the ward. Implementation status and effect of hand hygiene of medical staff on duty were examined randomly each month. At the same time MRSA infection rate of patients in comprehensive ICU was monitored in the same period. The relationship between hand hygiene compliance and MRSA infection rate was analyzed. Results The score of medical staff of cognition of hand hygiene was (41.70±3.67) points before the intervention, while the score was (44.10±3.55) points after the intervention. The difference had statistical significance (t=24.37, P<0.01). The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 68.75%, 14.58%, 66.90%, 12.90% respectively before the intervention. The correct rate of hand washing, positive rate of bacterial culture in hand, hand hygiene compliance and infection rate of MRSA of patients in comprehensive ICU were 88.54%, 3.12%, 74.14%, 3.10% respectively after the intervention. The difference had statistical significance (χ2=7.809-24.520, P<0.01). Conclusions Questionnaires with high credibility reviews could better identify issues in hand hygiene compliance, and sustained, reinforcing intervention measures could improve the compliance of hand hygiene; Good hand hygiene practice of medical and nursing staff contributes to controlling MRSA infection rates in general ICU.

2', 3', 5'-Tri-O-acetyl-N6-(3-hydroxylaniline)adenosine (WS070117) is a derivative compound of natural product cordycepin. It has significant lipids regulating activity and low toxicity which has been proved by in vitro and in vivo experiments. In this study, 1H NMR-based metabolomics was used to investigate the dose-related effects of WS070117 on hyperlipidemia of high-fat-fed hamsters. The hyperlipidemic hamsters were administrated with six different doses of WS070117, including 3, 12, 50, 100, 200 and 400 mg x kg(-1) x d(-1). 1H NMR spectra of hamster serum were visually and statistically analyzed using two multivariate analyses: principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA). As a result, WS070117-treated groups showed dose-related regulation of metabolites associated with lipid metabolism, choline metabolism and glucose metabolism. The dose of 3 mg x kg(-1) x d(-1) of WS070117 only exhibited a little lipids regulating activity. However, the doses of 12 and 50 mg x kg(-1) x d(-1) of WS070117 both regulated the contents of metabolites to reverse significantly toward normal levels. When the dose of WS070117 reached 100 mg x kg(-1) x d(-1), it was more effective than positive control drugs. The work suggested that NMR-based metabolomics might be a valuable approach to evaluate dose-related effects of lipids regulating compounds.

Objective To investigate the role of mitochondrial respiratory chain in the hyperpermeability of human peritoneal mesothelial cells (HPMCs) induced by high glucose peritoneal glucose PDS was also added. Transmesothelial electrical resistance (TER) measurement was examined for detection of permeability damage in HPMCs. Immunostaining and Western blotting analysis were used to detect claudin-1 expression. Mitochondrial superoxide (MitoSOX) Red staining and respiratory chain complexes activities were determined for detection of mitochondrial reactive oxygen species (ROS) production and mitochondrial complexes activities. Results TER was decreased in a time- and concentration-dependent manner after culture with high glucose PDS for was also down-regulated significantly by high glucose PDS (P＜0.01). Complex Ⅲ activity was inhibited (10.8% of control, P＜0.01) accompanied with increased mitochondrial ROS generation.These changes were partially prevented by glutathione. Conclusion Mitochondrial respiratory complex Ⅲ pathway has crucial importance in maintaining TER of HPMCs, which may reveal a valuable target for novel therapies to fight hyperpermeability of peritoneum during the prolonged PD treatment.

OBJECTIVE To evaluate the hand hygiene compliance(HHC) in China.METHODS The field observation for hand hygiene compliance,the hand hygiene material and equipment were performed in parallel in 8 hospitals from Beijing,Shanghai and Guangzhou.RESULTS It was shown that the average hand hygiene compliance before contacting patient was 35.3%,much lower than the compliance after contacting patient(56.5%).The nurse′s HHC(39.3%) was the best among groups before contacting patient,but the physicians took the first place of HHC after contacting patient.The best discipline in HHC was gynecology and obstetrics departments,especially before contacting patient and after contacting other surface,comparatively the worst was the surgeons.Most of hospitals(83.3%) provided the unmedicated detergent for handwashing.The alcohol-based hand rub(ABHR) for hand disinfection was available(56%) in many hospitals,in contrast the HHC with ABHR was quite low(14.2%).CONCLUSIONS These results indicated that the HHC is relatively low and improving adherence to hand hygiene practice is a multidisciplinary and systematic approach in China.It might be essential for promoting the HHC of health care workers,especially the physicians and surgeons,to strengthen the education and enlarge the continuous investment for some hard-ware improvement.
