Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.

AIM: To investigate the apoptosis in primary gastric cancer cells induced by resveratrol, and the relation between this apoptosis and expression of bcl- 2 and bax. METHODS: In in vitro experiments, MTT assay was used to determine the cell gowth inhibitory rate. Transmission electron microscopy and TUNEL staining were used to quantitatively and qualitively detect the apoptosis of primary gastric cancer cells before and after the resveratrol treatment. Immunohistochemical staining and RT - PCR was used to detect the expression of apoptosis - regulated gene bcl - 2 and bax. RESULTS: Resveratrol inhibited the growth of primary gastric cancer cells in a dose - and time - dependent manner. Resveratrol induced primary gastric cancer cells to undergo apoptosis with typically apoptotic characteristics. TUNEL assay showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the apoptotic indexs were 4.93% ± 0.19%, 16.74% ± 0.43%, 27.88% ±0.36%, 36.84% ± 1.07 % respectively. Immunohistochemical staining showed that after the treatment of primary gastric cancer cells with resveratrol for 24, 48, 72, 96 hours, the positive rates of Bcl - 2 proteins were 20.68% ± 0.49%, 10.84% ±0.33%, 6.80% ± 0.34%, 3.91% ± 0.15% and the positive rates of Bax proteins were 19.79% ± 0.98%, 30.74% ±0.85%, 40.14% ± 1.17%, 60.08% ± 1.64%. After exposed to resveratrol for 24 h, 48 h, 72 h and 96 h, the density of bcl- 2 mRNA decreased progressively with elongation of time and the density of bax mRNA increased progressively with elongation of time by RT- PCR. CONCLUSION: Resveratrol is able to induce the apoptosis in primary gastric cancer. This apoptosis may be mediated by down- regulation of Bcl- 2 and up- regulation of Bax.

Objective To investigate the correlation between drug resistance and β-actamase genes of multi-drug resistance Acinetobacter baumannii (MDR-AB) in neonatal intensive care unit to provide evidence for rational antibiotics administration and nosocomial infection control.Methods Twenty-six MDR-AB strains were separated and collected from clinical specimens.The minimum inhibitory concentrations of 13 antimicrobial agents were determined by agar dilution method.Genotypes of β-lactamase were detected by polymerase chain reaction.Results The resistant rates of the 26 strains to Ceftazidime,Cefoxitin,Piperacillin-tazobactam and Ciprofloxacin were 100.0%.About 80.8% to 96.2% of these strains were resistant to the other antimicrobial drugs.Among the 26 MDR-AB strains,100% (26/26) strains possessed oxa-51,77% (20/26) possessed oxa-23 gene,54% (14/26) carried arnpC gene,both oxa-23 and ampC were identified in 42% (11/26) strains,while oxa-24,oxa-58,imp-1,imp-4 and vim-2 gene were not identified.Conclusions The drug resistance of Acinetobacter baumannii is serious,oxa-23 and ampC are the major plactamase genes carried by MDR-AB in neonatal intensive care unit.

Objective;To explore the relationship among parents' negative punishment,children's self-concept,and children's social behaviors.Methods;Data were collected from questionnaires given to a sample of 612 children from primary and secondary schools and their parents.Results;The structural equation modeling results showed parents' negative punishments could influence children's social behaviors directly and indirectly.In the indirect approach,through the mediating role of children's self-concept,parents' negative punishments could make a negative role on children's pro-social and aggressive behaviors,and a positive role on children's withdrawn behavior.In the direct approach,parents' negative punishments could make a positive effect on children's pro-social,aggressive and withdrawn behavior directly.Conclusion;Children's self-concept plays a mediating role between the relationship of parents' negative punishments and children's social behaviors.

Objective To investigate the relationship between correlative factors of ambulatory arterial stiffness in-dex (AASI) and target organ damage (TOD) in patients with primary hypertensive. Methods A total of 330 hypertensive pa-tients were included in the study and divided into two groups according to the value of AASI:low AASI group (n=167) and high AASI group (n=163). The value of AASI was obtained from 24-hour ambulatory blood pressure monitor (ABPM). The clinical data were collected including general information, the data of ABPM, results of coronary angiography, left ventricular mass index (LVMI), estimated glomerular filtration rate (eGFR) and ankle brachial index (ABI) in two groups. Results There were significantly higher values of age (years:64.91 ± 9.70 vs 59.12 ± 10.00), the proportion of diabetes (33.8% vs 14.8%), the proportion of non-dipper patterns of hypertension (65.6%vs 43.7%), 24-hour pulse pressure (PP, mmHg:65.27± 11.31 vs 56.06±10.51), 24-hour diastolic blood pressure standard deviation(DBPSD, mmHg:9.64±2.47 vs 8.31±2.31), the number of coronary artery lesions (1.78±1.10 vs 1.27±1.07), LVMI (g/m2:125.74±29.65 vs 107.69±23.23) and the proportion of peripheral vascular disease (27.3%vs 16.4%) in high AASI group than those in low AASI group (P<0.01). The level of eGFR was significantly lower in high AASI group than that in low AASI group [mL/(min · 1.73 m2):85.31 ± 20.31 vs 99.67 ± 17.76]. There were positive correlation between AASI and coronary lesions (r=0.235), LVMI(r=0.168) and peripheral vascu-lar disease (r=0.167). And there was a negative correlation between AASI and eGFR (r=-0.187). The multiple linear regres-sion analysis showed that age, diabetes, PP, DBPSD and non-dipper patterns of hypertension were the predictors of AASI. Conclusion AASI correlated with age, diabetes, PP, blood pressure variability and non-dipper patterns of hypertension. The higher level of AASI may relate to the development of TOD in patients with primary hypertensive.
