Objective To evaluate the effect of alcoholism history on the elderly patients’early cognitive function after lower abdominal or limbs surgery under general anesthesia through controlled clinical trials.Methods Sixty male patients aged 65-80 years of ASA grade Ⅰ or Ⅱ were selected un-dergoing lower abdominal or limbs surgery,30 cases with alcoholism history as alcohol group(group A),30 cases without alcoholism experience as control group (group C).All patients were anesthe-tized intravenously.The general data before and during operation,and the postoperative complications were recorded.The mini mental state examination(MMSE)was performed to assess the cognitive function 1d before and 1,7 d after surgery,then post-operative cognitive dysfunction(POCD)was compared between the two groups through analysis of the MMSE score.Results The MMSE score of 1,7 d after surgery in two groups was significantly lower than that of the preoperative(P < 0.05 ). Compared with the score 1 d after surgery,the score of 7 d post-operation was significantly higher in group A (P <0.05).The postoperative score in group A were significantly lower than that in group C 1,7 d after surgery (P <0.05).The incidence of POCD in group A were higher than that in group C 1,7 d after surgery (P <0.05 ).Conclusion Alcoholism history can increase the incidence of early cognitive dysfunction in elderly patients after general anesthesia.

Objective To explore the level of the oxidative stress and the DNA oxidative damage of peripheral blood mononuclear cells (PBMCs) in pulmonary embolism (PE) patients after remission and in acute exacerbation.Methods The PBMCs DNA damage in 35 PE patients (test group) after remission and in acute exacerbation respectively and in 33 healthy persons (control group) was detected by single-cell gel electrophoresissingle (Comet assay).The total antioxidative capacity (TAC) in blood plasma was measured by phenanthroline colorimetric analysis.The contents of malondialdehyde (MDA) in blood plasma was measured by thiobarbituricacid colorimetric analysis.The capacity of glutathion peroxidase (GSH-PX) in blood plasma was measured by the method of improved Hafeman direct determination method (DNTB).Results The level of TAC,GSH-PX in test group after remission were significantly higher than those in acute exacerbation[(6.86 ± 1.21) kU/L vs.(5.18 ± 1.13) kU/L,(165.25 ± 41.96) kU/L vs.(137.23 ± 38.52) kU/L] (P ＜0.01),and they were all significantly lower than those in control group [(7.85 ± 1.44),(189.92 ± 51.32) kU/L] (P ＜ 0.01).The level of MDA in test group after remission was significantly lower than that in acute exacerbation [(5.58 ± 1.89) μmol/L vs.(7.26 ± 2.25) μmol/L] (P ＜ 0.01),and they were significantly higher than that in control group [(3.71 ± 1.52) μmol/L] (P ＜ 0.01).The arbitrary units (AU) of PBMCs DNA damage in PE patients after remission (29.01 ± 6.75) was significantly lower than that in acute exacerbation (42.13 ± 8.01),and they were all significantly higher than that in control group (15.12 ± 4.36),there were significant differences (P＜ 0.01).There were negative correlations between the PBMCs DNA damage and the level of TAC in PE patients after remission and in acute exacerbation (r =-0.695,P ＜ 0.01 ;r =-0.536,P ＜ 0.01).There were positive correlations between the PBMCs DNA damage and the contents of MDA in PE patients after remission and in acute exacerbation (r =0.513,P ＜ 0.01 ;r =0.628,P ＜ 0.01).There were negative correlations between the level of TAC and the contents of MDA in PE after remission and in acute exacerbation respectively (r =-0.534,P ＜ 0.01 ;r =-0.486,P ＜ 0.05).There were positive correlation between the level of TAC and GSH-PX in PE patients after remission and in acute exacerbation (r =0.512,P ＜ 0.01 ;r =0.497,P ＜ 0.01).Conclusions There are oxidation/antioxidation imbalance,oxidative stress and the PBMCs DNA damage in PE patients.There is positive correlation between the PBMCs DNA damage and the oxidative stress.After remission,the level of the oxidative stress and the PBMCs DNA oxidative damage in the same PE patients is improved respectively.

Objective To evaluate the effects of remifentanil on the proliferation,the cell cycle and apoptosis of human liver carcinoma cell line HepG2 in vitro.Methods Human liver carcinoma cells HepG2 were cultured in vitro.The HepG2 cells of the test group were incubated in the RPMI-1640 medium with remifentanil at different concentration(0.001,0.01,0.1,1,10,100,200 μmol/L).The HepG2 cells of the control group were incubated in the RPMI-1640 medium for 48 hours.The level of the cell proliferation was evaluated with methylthiazolyldiphenyl-tetrazolium bromide (MTT) method.The cell cycle was detected with flow cytometry (FCM).The morphological change of apoptosis cell was observed by fluorescence microscopy after staining by Hoechst33258.Results Remifentanil inhibited the proliferation of the HepG2 cells with a dose-dependent effect.Compared with control group,the cell proliferation capability was apparently decreased in the test group (P ＜ 0.05) when the concentration of remifentanil was over 1 μmol/L (P ＜0.05).However,no significant difference in cell proliferation was found when remifentanil was 100 and 200 μmol/ L.The ratio of G0/G1 phase of HepG2 cells was significantly enhanced and the ratio of S phase of HepG2 cells was significantly decreased when remifentanil was over 1 μmol/L.The fluorescent microscopy stained by the Hoechst33258 showed part of HcpG2 cells apoptosis in test group,and the apoptotic rate was significantly increased when remifentanil was over 1 μmol/L (P ＜ 0.05).Conclusions The data suggest that remifentanil would inhibit the proliferation of HepG2 cells and induce apoptosis when remifentanil was over 1 μmol/L.

Objective To explore the effects of urokinase type plasminogen activator (uPA) gene-modified bone marrow-derived liver stem cells ( BDLSC) transplantation on hepatocyte regeneration in CCl4-induced liver fibrosis rats. Methods Ten male Fisher 344 rats were donor rats of BDLSC. The BDLSC of male rat was transfected with AduPA. Thirty-six female Fisher 344 rats were equally divided into normal group (injected subcutaneously with olive oil) , model group (CCl4 induced the model, injected through tail vein with 0. 9% sodium chloride), BDLSC group (CCl4 induced the model, injected through tail vein with BDLSC) and gene transfected group (CCl4 induced the model,injected through tail vein with gene transfected BDLSC). Liver function and area of collagen were observed. The expression of hepatic growth factor ( HGF) and its receptor c-met mRNA in rats' liver tissues were tested by semiquantitative RT-PCR. The expressions of proliferating cell nuclear antigen (PCNA) in rats' liver tissues were determined by immunohistochemistry staining. Results The areas of collagen in normal group, model group, BDLSC group and gene transfected group was 0. 12% ± 0.03%, 14. 49%±1.40%, 8. 25%±0. 82% and 5. 12%±0. 40% accordingly, there were significant differences between groups (P<0. 05). Compared with model group and BDLSC group, the liver function of gene transfected group significantly improved, the serum levels of hyaluronic acid (HA),procollagen Ⅲ (PCⅢ) and the content of hydroxyproline in liver tissues decreased dramatically. The expression of HGF and c-met at mRNA levels were up-regulated significantly, and the expression of PCNA protein in liver tissues increased obviously. Conclusion uPA gene-modified BDLSC transplantation may induce proliferation of hepatocytes, and then improve the liver functions of fibrotic rats induced by CCl4.

Objective To explore the epidemiological characteristics of malaria in Liaoning Province from 1951 to 2014,so as to provide the evidence for further control of the disease. Methods The data of registered malaria cases in Liaoning Province from 1951 to 2014 were collected and analyzed with epidemiological methods. Results From 1951 to 2014,there were report-ed malaria cases each year. The peaks of incidence were in 1953,1962 and 1973,the incidence rates were 136.67/100000, 256.81/100000 and 35.89/100000 respectively and the numbers of patients were 27862,65460 and 11523,respectively. From 1977 to 2014,the incidence rates were all less than 1/100000. From 1951 to 1980,the occupations of patients were main-ly farmers,and from 1981 to 2014 were mainly workers,farmers and exported laborers. Conclusion The malaria endemic situ-ation in Liaoning Province experienced the periods from outbreaks to basically elimination,and the long-term surveillance will be the further working emphasis.

Objective To understand the trend and epidemiologic characteristics of malaria prevalence so as to provide the evidence for further control of the disease in Liaoning Province. Methods The data of registered cases of malaria in Liaoning Province from 2008 to 2013 were collected and analyzed with the descriptive epidemiological methods. Results A total of 202 ma-laria cases were reported from 2008 to 2013. There was no epidemic outbreak ,and the average annual incidence was 0.08/100 000. Totally 17 P. v. cases of local infection were reported,and 185 imported malaria cases were reported(P.v. 33 cases,P.f. 113 cases,P.v.&P.f. 13 cases,P.o. 3 cases,and unspecified 23 cases). The ratio of male to female was 5.91:1,the populations aged 31-45 years were the most(47.52%),and the main occupation was exported labors(46.04%). The 179 imported cases were infected in Africa and Southeast Asia,6 imported cases were infected in Anhui Province,Yunnan Province and Hongkong,and 16 local cases were infected in the border area of Dandong City. Conclusions Although the annual incidence of malaria in Liaon-ing Province is lower than 1/10 000,the incidence shows an increasing trend because the exported labors are increased. There-fore,the epidemic monitoring and health education should be strengthened,especially for the exported labors who have returned.
