Objective To observe the effect of single and low dose propofol administered near the end of surgery on the cardiovascular and adverse response during extnhation in patients undergoing ovarian cancer operation. Methods Fifty ASA Ⅰ - Ⅱ patients undergoing selective ovarian cancer operation were randomly allocated into group S and group P,with 25 patients in each group. In group S, inhalation of sevoflurane was discontinued at about 2 minutes before the end of operation. In group P, inhalation of sevoflurane was discontinued at about 5 minutes before the end of operation,and at the same time,0.5 mg/kg of propofol was administered intravenously. The systolic blood pressure (SBP),diastolic blood pressure (DBP),heart rate (HR) and recovery time of consciousness were recorded at 5 min before extubation (t_1),during extubation (t_2), 1 min after extubation (t_3), and 5 rain after extubation (t_4). The incidence of agitatian,bucking,nausea and vomiting were recorded by an observer who was blind to this study. Results There were statistical differences in HR,SBP,DBP at t_2-t_4 between two groups. The recovery time was (10.39 ± 1.26) min in group P,and(9.57 ± 1.25) min in group S,there was significant difference between group P (2 cases) and group S (9 cases)(P< 0.05). There was significant difference in the incidence of agitation between two groups (P< 0.05). Conclusion Low dose propofol before extubation can inhibit stress and cardiovascular response and decrease the incidence of agitation, bucking, nausea and vomiting.

Partial immunoactivities of peptidoglycan(PG)isolated from lactic acid bacteria were investigated.PG isolated from strain Z8 and Z17 of lactic acid bacteria respectively,had similar immunoactivities.The phagocytic function of M?(macrophage)increased markedly and serum lysozyme activity was significantly enhanced by injection of PG-extracts on mice.Investigation of immuno-enhancing effects of PG on vaccine of Newcastle disease in chickens showed that the hemagglutination inhibition levels of PG were higher than that of the control and the level was maintained for a longer time as compared to the control.

Objective:To summarize the influencing factors and the preventative strategies of transurethral resection syndrome(TURS) in transurethral vaporization of the prostate(TVP). Methods:Among the consecutive 1360 patients who underwent TVP from Feb 1998 to 2004 Dec,using Circon vaporization device and vaporizaton-resection electrode,irrigating with 5% GS,TURS occured in 12 cases.The clinical materials were reviewed retrospectively. Results:At the end of operation,serum sodium declined and blood glucose rose apparently in the TURS cases.Of the 12 patients,mean operative time was 136 min(90-180min),prostate volume were Ⅲ?(50-75 g),perforation of the prostate capsule occurred in 8 cases,chill occued in 8 cases.TURS occurrence rate was relatively high in the high risk cases.The 12 patients were cured. Conclusion:The risk of TURS that still exists during TVP is relevant to: perforation of the prostate capsule,operative time,irrigating pressure,the high risk cases,prostate volume and(so on.)

Objective To evaluate the value of intraduetal ultrasonography (IDUS) in diagnosing biliary and pancreatic disorders. Methods The findings by endoscopic retrograde cholangiopancreatography (ERCP) and IDUS from 19 patients with suspected biliary and pancreatic disorders from July 2006 to August 2007 in our hospital were analyzed retrospectively. Results Of the 19 patients, 17 had obstructive jaundice (including 6 eases of cholangiocarcinoma, 2 pancreatic adenocareinoma, 2 gallbladder carcinoma, 2 chole-docholithiasis with bile duct stricture, 2 autoimmune pancreatitis, 1 papillary adenocarcinoma, 1 papillary adenoma, and 1 sclerosing cholangitis) and 2 intraduetal papillary mueinous tumor (IPMT). The diagnosis was confirmed by surgery and pathological findings in 11 patients. The diagnostic accuracy of ERCP and IDUS was 73. 7% (14/19) and 84. 2% (16/19), respectively, and that of ERCP combined with IDUS was 89. 5% (17/19). The sensitivity and specificity of ERCP to differentiate benign bile duct strictures from ma-lignant ones were 100. 0% (11/11) and 83.3% (5/6), respectively; and those of IDUS were 100. 0%(11/11) and 100. 0% (6/6), respectively. The sensitivity and specificity of ERCP in diagnosing cholan-gioeareinoma were 83.3% (5/6) and 60% (3/5), respectively; and those of IDUS were 100. 0% (6/6) and 40. 0% (2/5), respectively. Conclusion Combination of ERCP with IDUS can improve the diagnostic accuracy of pancreaticobiliary disorders. Additionally, IDUS shows higher sensitivity and specificity in differ-entiation between benign and malignant bile duct strictures, but it is still difficult to identify the etiologic factors of malignant bile duet strictures by IDUS.

Objective To investigate the level change of glucose excursion , 8-iso prostaglandin F 2α( 8-iso-PGF2α) in type 2 diabetes mellitus(T2DM), and its effects on nonalcoholic fatty liver disease (NAFLD).Methods A total of 62 inpatients with type 2 diabetes mellitus including T2DM group(DM, 30 cases) and T2DM with NAFLD group(DM+NAFLD, 32 cases) were recruited from October 2012 to November 2013 , normal glucose tolerance group had normal glucose tolerance ( NGT;30 cases ) with normal physical examination results.The age, gender, duration, blood pressure, body mass index (BMI), and blood lipid among three groups were no statistical difference .The clinical data of each patient were collected by professional people .Blood lipids and glycated hemoglobin (HbA1c) were detected.Oral glucose tolerance test (OGTT) were taken in all groups.The Postprandial glucose excursion (PPGE), blood glucose standard deviation (SDBG), mean blood glucose and (MBG) and HbA1c were used to evaluate the glucose excursion.Serum 8-iso-PGF2αwas detected by enzyme-linked immunosorbent (ELISA) to evaluate oxidative stress.Inter-group com-parison was conducted with analysis of variance ( ANOVA) .Correlation analysis was used to evaluate the factors of influence .Results⑴The levels of PPGE[(7.34 ±2.23) mmol/L vs (8.52 ±2.43) mmol/L],SDBG[(2.43 ±0.90) mmol/L vs (2.80 ±0.78) mmol/L], MBG[(11.06 ±1.76) mmol/L vs (13.65 ±2.83) mmol/L], and HbA1c [(7.59 ±1.02)% vs (8.05 ±1.52)%] in T2DM group and T2DM with NAFLD group were significantly higher than that in NGT group (both P <0.05); and that in NAFLD group have significantly rise than that in DM group ( P <0.05), but there was no significant difference in HbA 1c between groups.⑵ The level of serum 8-iso-PGF2αwas gradually increased from NGT group [(33.45 ±8.60) pg/ml], DM group [(47.33 ±15.30) pg/ml], to DM +NAFLD group [(56.07 ±13.10) pg/ml], with statistically significant difference ( P <0.05);⑶The Person corre-lation analysis showed that the content of serum 8-iso-PGF2αwas positively correlated with PPGE, SDBG, and MBG ( r =0.796, 0.778 , 0.712 , P <0.01 ) .Conclusions Serum 8-iso-PGF2αis a better parameter to reflect the status of body oxidative stress .The level of oxidative stress is increased with the increase of glucose excursion in T 2DM, which is the important mechanism of its complica-tions of NAFLD.

Objective To explore the risk factors of vascular cognitive impairment (VCI)among Chinese population, and to clarify the scientific evidences for further prevention and treatment.Methods PubMed,CNKI,CBM,VIP and Wangfang databases (from 2002.1 to 2013.1)were searched to collect case-control studies or cohort studies studying risk factors of VCI among Chinese population. Meta-analysis was performed to calculate combined odds ratio (OR)or mean difference (MD)and its 95% confidence interval (95%CI).Results A total of 42 proper papers involving 3 282 cases and 7 815 controls were included in the review.For categorical variables,pooled OR and its 95% CI were as follows:hypertension 2.56 (2.03 - 3.21 ), hyperlipidemia1.79 (1.39 - 2.30 ), hyperglycemia 2.46 (1.90-3.19),Leukoaraiosis 5.46 (2.60-11.46),cerebral infraction multiple foci 4.39 (2.61-7.38),stroke history3.79(2.35-6.11),left hemisphere lesions 2.13(1.42-3.20),smoking 1.51 (1.08-2.11),drinking 0.99(0.73-1.36),basal ganglia lesions 2.15(1.55-2.99),thalamus lesions 2.34(1.57-3.47);for continuous variables,MD and its 95%CI were as follows:level of TG 0.35(0.15-0.55),level of TC 0.44(-0.16-1.04),level of folic acid -4.10(-5.50- -2.69),vitamin B12 -130.44(-225.46--35.41).Conclusion Except for drinking and level of TC, hypertension, hyperlipidemia, hyperglycemia, leukoaraiosis,cerebral infraction multiple foci,stroke history,left hemisphere lesions,smoking,basal ganglia lesions,thalamus lesions,high level of TG,low level of folic acid and vitamin B12 might be the risk factors of VCI among Chinese population.

Objective To study the relationships between cognitive impairment in patients with lacunar infarcts and quantitative CT measures and to determine the independent correlative factors of cognitive impairment. Methods Neuropsychological examination was conducted for 128 patients with acute lacunar infarct. Number, location, and volume of infarcts, cerebral atrophy index and severity of white matter lesions (WMLs) were measured and recorded. Results The number of lacunar infarcts in cognitive impairment (CI) group was significantly larger than that in cognitive normal (CN) group. Mean width of sulcus and sylvian fissure, index of frontal horn and ventricular-brain ratio (VBR) were significantly different in both groups. There were more patients with 3 grades or 4 grades WMLs in CI group (62%) than those in CN group (22%). The total volume of lacunar infarcts showed no statistically significant difference. Logistic regression analysis indicated that the number of lacunar infarcts in frontal subcortex and thalamus, the volume of infarcts in anterior periventricular white matter, width of cerebral sulcus and sylvian fissure were correlated with cognitive impairment respectively. Additionally, age and education were correlative factors of cognitive impairment in patients with lacunar infarct. Conclusion Correlative factors of cognitive impairment in patients with lacunar infarct are not merely one feature, but a combination of infarct features (number, location, and volume), cortical atrophy and host factors (age and education).
