ObjectiveTo study the changes of immune function after hepatectomy for hepatocellular carcinoma(HCC) in patients with liver cirrhosis.MethodsPatients with liver cirrhosis were used as control group,CD4?CD8?CD4/CD8? and protein expression level of IFN ??IL2?IL10 in peripheral blood from 18 advanced HCC cases with liver cirrhosis before and after heaptectomy were detected by flow cytometry(FCM) and ELISA.Results Postoperative CD4(33?3)%?CD4/CD8(1 1?0 1)?IL2(71?11)?pg/ml?IFN ?(90?15)?pg/ml level elevated compared to that of pre operation 〔CD4(29?4)%?CD4/CD8(0 9?0 3)?IL2(57?15)?pg/ml?IFN ?(78?13)?pg/ml〕(all P

Objective To study the pretreatment with prostaglandin E1 ( PGE1 ) on acute superior mesenteric ar-tery ( SMA) ischemia reperfusion injury of intestinal cell in rats. Methods 18 healthy male SD rats were randomly divided into control group, sham operation group and experimental group. IRI of SMA model was made by clamping the SMA for one hour and two hours after reperfusion in the control group and the experimental group,respectively. PGE1(20 μg/kg) was injected from the tail vein in the control group and the experimental group. Character of pa-thology of small intestine was examined. The expression of Bax and Bcl-2 in small intestine cells and change of IF-ABP and DAO in serum were detected. Results Pathologic changes showed that there was no change in the control group;while in the sham operation group,chorionic epithelium mucosa ulceration and hemorrhage and necrosis oc-curred more seriously than that in the experimental group. Expression of Bax and Bcl-2 was higher in the sham op-eration group and the experimental group than that in the control group(P<0. 05), and it was obviously lower in the experimental group than in the sham operation group(P<0. 05). The content of IFABP and DAO in blood ser-um:it was higher in the sham operation group and the experimental group than in the control group ( P<0. 05 ) , and it was lower in the experimental group than in the sham operation group(P<0. 05). Conclusion PGE1 can relieve the alvine necrosis caused by rats' mesenteric reperfusion injury after acute artery ischemia and thus protect damaged mucosa of small intestine.

OBJECTIVE To investigate the distribution and antibacterial resistance of nosocomial infection from a new hospital pathogens,and provide reference for clinical rational use of drugs.METHODS Statistical methods were used to analyze the data of pathogen′s formation,distribution and antibacterial resistance of a new hospital.RESULTS A total of 1852 clinical isolates were collected from Mar 2005 through Mar 2007,of which Gram-negative microorganisms and Gram-positive cocci accounted for 71.0 % and 29.0%,respectively.The most commonly encountered pathogens were Pseudomonas aeruginosa,Escherichia coli,Klebsiella spp,Acinetobacter,Staphylococcus aureus and coagulase-negative Staphylococcus.Except Acinetobacter,up to 6% strains of Gram-negative microorganisms were resistant to the imipenem,meropenem and piperacillin/tazobactam;Gram-positive cocci were still highly sensitive to vancomycin and teicoplanin.CONCLUSIONS A new hospital is similar with other hospitals in the data of formation,distribution and antibacterial resistance of nosocomial infection pathogens.

Objective To investigate the expression of soluble triggering receptors expressed on myeloid cells-1 ( sTREM-1 ) in intraperitoneal drainage fluid of patients with abdorminal trauma and its predictive value for post-traumatic sepsis. Methods A total of 80 abdominal trauma patients were served as the trauma group and 25 patients treated with subtotal gastrectomy as the control group.Intraperitoneal drainage fluid sTREM-1,serum sTREM-1,procalcitonin (PCT) and C-reactive protein (CRP)at 0,24,48,72 hours after admission were determined in two groups for assessing their value in early prediction of post-traumatic sepsis. Results The levels of drainage fluid sTREM-1,serum sTREM-1,PCT and CRP in the trauma group were significantly higher than those in the control group (P ＜ 0.05 ).Drainage fluid sTREM-1 showed the area under the receiver operating characteristic (ROC) curve,sensitivity and specificity for 0.84,77％,and 83％ in the prediction of post-traumatic sepsis,which was superior to the serum sTREM-1,PCT and CRP. Conclusion Intraperitoneal drainage fluid sTREM-1 has high accuracy in predicting the sepsis in abdominal trauma patients.

ObjectiveTo investigate the correlation between PTEN and p27 expression in gastric carcinoma. MethodsImmunohistochemistry was applied to examine the expression of PTEN and p27 in 49 cases of human gastric carcinoma,49 cases of tumor-side ward mucosa and 13 cases of normal gastric mucosa.ResultsPositive expressive rates of PTEN and p27 protein in colorectal carcinoma were 61.22 ％(30/49)and 57.14 ％ (28/49),which were lower than those in tumor-side ward mucosa [91.84 ％(45/49) and 93.88％(46/49)]and normal colorectal mucosa [100 ％(13/13)and 100 ％(13/13)](P＜ 0.05). The expression of PTEN and p27 in gastric carcinoma correlated with each other (r=0.580,P=0.005),and which were associated with degree of differentiation of carcinoma,PTNM stage and lymph node metastasis of the tumors.Conclusion The abnormal expression of PTEN and p27 participate the malignant conversion process of the gastric mucosa cell and the expression levels of PTEN and p27 protein may be used to evaluate the pathologic biology behavior of gastric carcinoma.

Objective To investigate the risk factors for ischemic stroke in Uygur population in Xinjiang, China. Methods Using a case-control study mode, 504 Uygur patients with first-ever ischemic stroke and 507 Uygur healthy subjects w ere investigated in accordance w ith the principle of the ethnic, sex, and age matching. The risk factors for ischemic stroke w ere screened. Results Multivariate logistic regres-sion analysis showed that the obesity (odds ratio [OR] 4.82, 95% confidence interval [CI] 1.80-12.94;P=0.002), hypertension ( OR 8.20, 95%CI 4.93-13.51; P<0.001), and heart disease ( OR 2.40, 95%CI 1.07-5.39;P=0.033) w ere the independent risk factors for ischemic stroke in Uygurs. While the education level of junior high school or above ( OR 0.38, 95%CI 0.18-0.81;P=0.012), tea drinking habit ( OR 0.22, 95%CI0.06-0.70; P=0.021), siesta habit ( OR 0.38, 95%CI 0.24-0.59; P<0.001), high levels of high-density lipoprotein cholesterol ( OR 0.34, 95%CI 0.20-0.59; P<0.001), and apolipoprotein A ( OR 0.23, 95%CI 0.07-0.77; P=0.017) were the protective factors for ischemic stroke. Conclusions The risk factors for ischemic stroke are more and typical in Uygur population in Xinjiang, China. Adjusting the diet structure of Uygurs, less taking meats and high-salt diet, intaking high fiber foods and fish, and appropriate physical exercise w il play an important role for the prevention of stroke in Uygur population.
