Objective To study the abnormalities in defecation of patient after laparoscopic cholecystectomy as well as the influencing factors. Method A self-designed questionnaire and the anxiety self-rating anxiety scale (SAS) were used to investigate the defecation conditions of patients after laparoscopic cholecystectomy. Results About 40.78% of the patients were normal in defecation after the surgery. Among those with abnormalities in postoperative defecation, 30.16%had diarrhea. The influenced factors included age, preoperative gallbladder function, daily diets and anxiety. Conclusions The abnormalities in defecation of the patients after laparoscopic cholecystectomy are common. The patients with young age, the gallbladder function before laparoscopic cholecystectomy and anxiety diet without limit need more attention.

Objective To assess the relationship between the concentration of total suspended particle (TSP) and cerebral-cardiovascular disease mortality of urban residents in Fushun city, China. Methods The data of cerebral-cardiovascular disease mortality and TSP concentration from 1999 to 2003 in Fushun city were collected. The association between TSP concentrations and the mortality of cerebral-cardiovascular diseases was analyzed using Poisson regression model adjusted for seasons, long-term patterns and meteorological variations using an ecological parametric method. Results As the concentration of TSP increased by 50 ?g/m3, OR of cerebral-cardiovascular disease mortality increase was 1.015 42 (95%CI=1.000 18-1.030 89) in the male group and 1.022 40 (95%CI=1.004 87-1.040 23) in the aged male group respectively, as 4-days lag TSP concentration increased by 50 ?g/m3, OR of cerebral-cardiovascular disease mortality increase was 1.008 26 (95%CI=1.000 57-1.016 02) in the whole people, 1.016 27 (95%CI=1.006 71-1.025 93) in the male group and 1.016 65 (95%CI=1.005 25-1.028 19) in the aged male group respectively. Conclusion Air pollution by TSP is considered as a risk factor for the increase of cerebral-cardiovascular disease mortality in Fushun city, China.

Objective To investigate the preventive effects of midazolam and propofol on liver against hypoxia/reoxgenation(H/R) injury in rats.Methods Twenty-four Wistar rats of both sexes weighing 200-250g were randomized into four groups:control group(group A),hypoxia/reoxygenation(group B),H/R + midazolam(group C) and H/R + propofol(group D).The 8-iso-prostaglandin F2?(8-iso-PGF2?) levels in the hepatic tissue were determined by enzyme-linked immunosorbent assay(ELISA).The contents of nitric oxide(NO) and the activity of nitric-oxide synthase(NOS) in hepatic tissue were determined by biochemistry methods.Results After hypoxia and reoxgenation injury in rats,the 8-iso-PGF2? level of hepatic tissue in group B was significantly higher than that in group A(P

Objective To investigate the protective effects of propofol on liver against hypoxia/reoxgenation (H/R) injury in rats. Methods Twenty-four Wistar rats of both sexet weighing 200-250g were randomized into control group (group A), hypoxia/reoxygenation group (group B) and H/R + propofol group (group C). The 8-iso-prostaglandin F 2? (8-iso-PGF 2? ) level in the hepatic tissue was determined by enzyme-linked immunosorbent assay (ELISA). The content of NO and the activity of NOS were assessed by biochemical methods. Results In group B, the 8-iso-PGF 2? level in hepatic tissue was significantly higher than that in group A (P

Objective To compare difference of nt and aa of H gene between the measles virus strains(MVW) recently circulating and used vacci ne strain (Chang-47) in Liaoning province of China, and to study biological an d immunological characteristic and genotype of MVW and Chang-47. Method s The analysis of 1～1 800 nt and 1～600 aa abou t H gene of MVW and Chang- 47 vaccine strain was performed. Neutralization test was performed against MVW and Chang-47 vaccine strain in the sera of measles cases and children vaccinated after 30 days. Results The genoty pe of the MVW was different from genotypes previously described in other c ountries and vaccine strain (Chang-47) used in Liaoning province. It also showe d that 18～28 aa were distinct from aa of other genotype, but most of the importa nt biological and immunological sites were not changing except the site at aa 24 0 .Neutralization antibody titer GMT against MVW and Chang-47 strains were no sig n ificantly different in the sera of measles cases and the children vaccinated af te r 30 days, but antibody titers GMT of the measles cases sera against MVW or Cha ng-47 strain were much higher than children vaccinated. Conclusions There was nt variation in the MVW. Most of biological and immunological a a sites of the MVW and Chang -47 strains were the same and were not changing. C hang -47 vaccine may also protect from infection of the MVW.

Codon is an important carrier of genetic information in organisms. In evolution, codon bias is formed in many organisms. In this study, the analysis of expressed genes in Lonicera japonica Thunb. is presented. The codon bias of genes with complete coding region is analyzed through CodonW. And we calculated the codon usage bias of hydroxycinnamoyl-CoA: quinate hydroxycinnamoyl transferase (HQT) genes. The results showed that L. japonica were bias toward the synonymous codons with A and T at the third codon position.

Objective To evaluate the effect of sevoflurane on liver injury in a pig model of hemorrhagic shock.Methods Twenty-four Bama miniature pigs of both sexes,weighing 20-25 kg,aged 3-5 months,were equally randomized into 3 groups using a random number table:sham operation group (group S);hemorrhagic shock group (group HS);sevoflurane group (group Sev).Hemorrhagic shock was induced by withdrawing 40％ of blood volume from the right femoral artery within 15 min (30 ml/kg) in HS and Sev groups.The animals inhaled 2％ sevoflurane for 30 min after establishment of the model in group Sev.Before hemorrhagic shock (T0),and at 30,60,90,120,180 and 240 min after hemorrhagic shock (T1-6),blood samples were collected from the femoral artery for determination of plasma alaninc aminotransferase (ALT) and betaine-homocysteine S-methyltransferase (BHMT) concentrations (by enzymelinked immunosorbent assay).After blood sampling at T6,the animals were sacrificed,and the right lobes of livers were removed for examination of the pathological changes with light microscope.Results Compared with group S,the plasma ALT concentrations were significantly increased at T4-6,the plasma BHMT concentrations were significantly increased at T3-6 (P＜0.05),and significant liver pathological changes were observed in HS and Sev groups.Compared with group HS,the plasma ALT concentrations were significantly decreased at T4-6,the plasma BHMT concentrations were significantly decreased at T3-6 (P＜0.05),and the liver pathological changes were significantly attenuated in group Sev.Conclusion Sevoflurane can mitigate liver injury in a pig model of hemorrhagic shock.

Objective To evaluate the changes in the expression of aquaporin-8 (AQP8) in intestinal mucosa in pigs with hemorrhagic shock.Methods Sixteen Bama miniature pigs,weighing 22-25 kg,were equally and randomly divided into sham operation group (group S) and hemorrhagic shock group (group HS).The animals were fasted for 8 h before operation.The animals were anesthetized with propofol 3 mg/kg injected via the auricular vein,and tracheostomized and mechanically ventilated.In group S,the femoral artery and internal jugular vein were only cannulated.In group HS,the femoral artery and internal jugular vein were cannulated for blood pressure and mean arterial pressure monitoring and blood sampling.Hemorrhagic shock was then induced by removing 40 percent of blood volume over 15 min.Before anesthesia (T0),and at 30 min and 1.0,1.5,2.0,3.0 and 4.0 h after the end of blood-letting (T1.6),blood samples were collected for determination of serum D-lactate and intestinal fatty acid binding protein (I-FABP) concentrations.After blood sampling at T6,the pigs were sacrificed,and intestinal specimens were obtained for microscopic examination and for determination of AQP8 cotent in intestinal mucosa (by ELISA).The water content of intestines was calculated by wet/dry weight ratio.Results Compared with group S,the serum D-lactate concentrations at T2-6,I-FABP concentrations at T1-6,and water content of intestines were significantly increased,and the cotent of AQP8 was up-regulated at T6 in group HS.No changes were found in the intestinal mucosa in group S.In group HS,severe damage to the intestinal mucosa was found,and bleeding,inflammatory cell infiltration,and epithelial cell necrosis were observed.Conclusion The mechanism of hemorrhagic shock-caused damage to intestines is related to up-regulated expression of AQP8 in intestinal mucosa in pigs.
