Objective To compare the surgical outcomes between laparoscopic and open surgeries in treatment of ectopic oviduct pregnancy, and investigate the clinical value of laparoscopic surgery. Methods Two hundred and forty-six patients with ectopic oviduct pregnancy in our hospital from June 2009 to March 2013 were retrospectively analyzed. 134 cases were treated with laparoscopic operation and 112 with open surgery. Some parameters such as operative time, blood loss, usage of pain-killer, hospital stay were compared between both groups. Results All operations were successful. Laparoscopic surgery was shown to be superior to open operation in the parameters of operative time, blood loss, usage of pain-killer and hospital stay ( < 0.05) . Conclusion Compared with open operation, laparoscopic surgery has the advantages of less trauma and rapid postoperative rehabilitation. It may become the first line treatment for ectopic oviduct pregnancy.

Objective To investigate the predictive value of whole nodule size and solid component size of pulmonary subsolid nodules (SSNs)with different window setting on preoperative HRCT for pathologic grade in lung adenocarcinoma.Methods We retrospectively evaluated preoperative chest HRCT and pathological data of 125 patients with 127 surgically resected lung adenocarcinoma manifesting as SSNs.All specimens were divided into two groups:a total of 69 SSNs in group A,including 22 adenocarcinomas in situ (AIS) and 47 minimally invasive adenocarcinoma (MIA);a total of 58 SSNs in group B,including invasive adenocarcinoma (IAC).Observer 1 used computer aided diagnosis software to measure the volume of whole nodule with lung window setting (WNLW),volume of solid component with lung window setting (SCLW),volume of solid component with mediastinal window setting (SCMW) and volume of solid component with threshold of-300 HU(SCT) of all SSNs.Observer 2 randomly selected 50 SSNs and repeated all the measurements.The interobserver agreement regarding quantitative measurements were evaluated by using intraclass correlation coefficient(ICC).The differences of all quantitative features between two groups were evaluated by Mann-Whitney U test.All the quantitative features were evaluated by using univariate logistic regression analysis,significant quantitative features identified by univariate logistic regression analysis were included in the multivariate logistic regression and independent predictors of pathological grade were obtained.Receiver operating characteristic analysis was conducted for the independent predictive factors that exhibited statistically significant differences in the multivariate logistic regression.Results The interobserver agreement regarding quantitative features were excellent (ICC> 0.75).The WNLW,SCLW,SCMW and SCT of group B were significantly larger than those of group A (P< 0.001).The univariate logistic regression analysis indicated that WNLW,SCLW,SCMW and SCT were significant (P<0.001),the multivariate logistic regression analysis indicated that SCT was the independent predictive factor (OR=1.013,95%CI:1.006—1.020,P<0.001).When SCT larger than 139.00 mm3,SSN was significantly associated with IACs (AUC=0.887,sensitivity=81%,specificity=93%).Conclusion SCT of SSNs on preoperative HRCT can be used to distinguish between AIS-MIA and IAC,which may provide information for choice of operation.

Objective To investigate the apoptosis of T lymphocytes,the expression of Bcl-2, Fas on the peripheral blood T lymphocytes in end stage renal disease patients;and to explore the characteristics of Th1 /Th2 profile and the influence of dialysis membranes with different permeability on the apoptosis of T lymphocytes of maintenance hemodialysis patients.Methods The study included 10 non-dialyszed (ND)patients,45 maintenance hemodialysis patients with cellulose acetate (CA) membranes(13),low-flux polusulfone(PS-LF) membranes(16),high-flux polusulfone (PS-HF) membranes (16) and 8 healthy volunteers (C).The apoptosis of T lymphocytes,expression of Bcl-2,Fas on peripheral blood T lymphocytes cultured with phytohemagglutinin (PHA) stimulation for 24 hours were measured by flow cytometry and immunohistochemical.ELISA was performed for detecting the levels of IFN-?and IL-4 in culture supematants.Results In ESRD patients,the apoptosis of T lymphocytes was greater than that of group C.Group CA was greater than group PS-HF and group PS-LF (P<0.05).The expression of Bcl-2 on T lymphocytes in ESRD patients was lower than that of group C (P<0.05).There was negative correlation between the T lymphocytes apoptosis and Bcl-2. The expression of Fas on T lymphocytes in ESRD patients was greater than that of group C (P<0.05), and it was positive correlated with T lymphocytes apoptosis.The level of IFN-?of ESRD patients was decreased significantly compared with that in group C (P<0.05),and there was negative correlation between T lymphocytes apoptosis and IFN-?.IL-4 was increased in ESRD patients (P<0.05) and it was positive correlated with T lymphocytes apoptosis.Conclusions The accelerated apoptosis of T lymphocytes in ESRD patients may be related to the expression of Bcl-2 and Fas of T lymphocytes.ESRD patients show a suppressed secretion of IFN-?and an increased secretion of IL-4. T lymphocytes apoptosis of maintenance hemodialysis patients is influenced not only by the biocompatibility but also by the permeability of the dialysis membrane.

Objective:To investigate the effects of oxymatrine(OM)on the apoptosis of human hepatoma HepG2 cells and its possible mechanisms.Methods:HepG2 cells were treated with different concentrations of OM.The proliferation inhibition was measured by MTT assay and the apoptosis of HepG2 cells were examined by Hochest staining method.Flow cytometry was used to analyze the cell cycle distribution and apoptosis rate.The expression of caspase-3,Bcl-2,Bcl-x_L and Bax proteins was assayed by Western blotting assay.Results:OM inhibited HepG2 cells growth in a time-and dose-dependent manner.After treatment with OM for 24 hours,some cells appeared typical apoptotic characteristics and the apoptosis rate was increased. Treatment with OM also increased caspase-3 activity and Bax expression in HepG2 cells,and decreased the expression levels of Bcl-2 and Bcl-x_L.Conclusion:OM can induce HepG2 cell apoptosis,which may be related to the down-regulation of PI3K/Akt signal pathway,suppression of Bcl-2 and Bcl-x_L activity,and activation of caspase-3.
