ObjectiveTo discuss the effect of palliative drainage operation on the life quality of hilar cholangiocarcinoma. MethodsCholangiocarcinoma data of our hospital in recent 21 years were analysed retrospectively. They were divided into four groups: RouxenY choledochojejunostomy group, bridge internal drainage group, PTCD (or ERBD) internal drainage group, and operative external drainage group. The operative mortality, incidence of postoperative cholangitis and survival period were compared among groups.ResultsThe total perioperative mortality of 193 cases of palliative operation was 9.3%, there was no difference among groups (P＞0.05). The rate of postoperative cholangitis in the bridge internal drainage group (10.0%) was lower than that of RouxenY choledochojejunostomy group (19.4%),P＜0.05, the rate of cholangitis in PTCD (or ERBD) internal drainage group (37.5%) and operative external drainage group (38.1%) were significantly higher than that of RouxenY choledochojejunostomy group (P＜0.01). There was no significant difference between RouxenY choledochojejunostomy group 〔(9.2±1.8) months〕 and PTCD (or ERBD) internal drainage group 〔(8.8±1.9) months〕 in survival period (P＞0.05)，but the survival period of the above groups were significantly higher than that of bridge internal drainage group 〔(6.5±1.6) months〕，P＜0.05, and operative (or PTCD) external drainage group 〔(4.3±2.0) months〕,P＜0.01.ConclusionThe life quality of RouxenY choledochojejunostomy group is better than that of bridge internal drainage group and PTCD (or ERBD) internal drainage group, the life quality of external drainage is worse than that of the other groups.
ObjectiveTo construct a hepatocellular carcinoma (HCC) cell line stably transfected with linamarase (lis) gene from cassava, and to study its biological characteristics. MethodsLis DNA was amplified from cassava by PCR and cloned into the pcDNA3.1(+) plasmid. Then the recombinant plasmid pcDNA3.1/lis was transfected into human HCC HepG2 cell line using lipofectamineTM 2000 and G418 selection. The stably transfected cell lines HepG2/lis was identified by immunofluorescence, RT-PCR, and Western blot. The enzyme activity of lis in cells was assayed by Lambert method. The characteristics of the new cell lines were checked by several methods: the cell growth curve was observed by MTT, cell cycle was analyzed by flow cytometry, and characteristics of tumor formation in vivo were detected in nude mice. ResultsLis from the cassava could stably integrate into eukaryotic cells, and package the same protein as lis with β-glucosidase activity. The stable integration of lis in cells did not interfere with cell morphology, growth characteristics, cell cycle, and tumorigenesis in vivo significantly. ConclusionsA new HCC cell lines transfected with lis is successfully established, which may lay an experimental foundation for the study of HCC treatment by using lis suicide gene system in future.

【Abstract】ObjectiveTo measure the expressions of Fas/FasL mRNA in normal liver, adjacent non-cancerous liver parenchyma and hepatocarcinoma, and to explore the relationship between the expressions of Fas/FasL mRNA in those tissues and the hepatocellular carcinogenesis. MethodsSemi-quantity reverse transcript-ploymerase chain reaction(QRTPCR) were performed to measure the relative quantity of the Fas and FasL mRNA expressions in normal liver (n=25), adjacent noncancerous liver parenchyma(n=40) and hepatocarcinoma(n=40). ResultsThe relative quantity of Fas and FasL mRNA expressed in normal liver, adjacent non-cancerous liver parenchyma and hepatocarcinoma were 0.792±0.039 vs 0.245±0.043，0.857±0.031 vs 0.429±0.035 and 0.473±0.047 vs 0.185±0.041, respectively. The relative quantity of Fas mRNA expression in hepatocarcinoma was lower than that of normal liver tissue and adjacent non-cancerous liver parenchyrna (P＜0.05). The relative quantity of FasL mRNA expression in hepatocarcinoma was also lower than that of normal liver tissue (P＜0.05) and adjacent non-cancerous liver parenchyma (P＜0.01), but its expression in adjacent non-cancerous liver parenchyma was higher than that of normal liver tissue (P＜0.05).ConclusionHepatorcarcinoma may escape the immune surveillance of the host, not only by means of reducing Fas expression, but also through adjacent non-cancerous liver parenchyma’s increasing expression of FasL to induce apoptosis of contact lymphocyte which highly expresses Fas.
Objective To investigate the difference in first onset age, family history and medication compliance between male and female patients with schizophrenia in communities. Methods We used self-designed questionnaire to survey and analyze 372 cases of schizophrenia between June to August 2014. Results There were no significant differences between male and female schizophrenic patients in the family history, personality before the disease, education level, age, and the onset type and disease course (P > 0.05). The first onset age of male patients [(24.92±8.22) years] was significantly earlier than female patients [(27.02±11.28) years] and the difference was statistically significant (P < 0.05). The number of unmarried male patients (115, 58.97%) was significantly more than unmarried females (81, 45.76%) and the difference was statistically significant (P < 0.05). The full medication compliance rate of female patients (127, 71.75%) was significantly better than that of male patients (115, 58.97%) (P < 0.05). Conclusion The first onset age, marital status and medication compliance are significantly different between the two genders of patients with schizophrenia, which indicates that prevention, treatment and recovery measures for male and female patients should be differentiated.
Objective To investigate the suicide related factors of the teenagers after trauma and further discuss the prevalence and related factors of suicide idea plan and behavior. Methods Using the general information questionnaire and the Youth Risk Behavior Survey (YRBS) to investigate the primary and secondary students in the nine worst-hit areas in Wenchuan earthquake of 2008, with cluster random sampling and the class as a sampling unit, to extract random 110 primary and middle schools and gather their general information, disaster-related cases and scores of suicide in YRBS. According to the different types of data, we used descriptive statistics,t test,Chi square test and Logistic regression analysis and respectively use single factor analysis and multivariate logistic regression analysis for suicide idea, plan and behavior. Results A total of 7 833 questionnaires were sent out and a total of 7 521 questionnaires were collected and the recovery rate was 96. 02%. Among them, there were 6 875 valid questionnaires (91.41%) and 636 invalid questionnaires. According to the investigation, the prevalence of the primary and secondary students which had seriously considered suicide was 6. 90%, which had a plan to commit suicide was 4.00% and which tried to take over the action of suicide was 2.70%. With general information for the independent variable, logistic regression analysis showed that whether there had seriously considered suicide as the dependent variable: age (OR=1.178, 95%CI 1.098 to 1.178) and changed in family structure after the earthquake (OR=1.360, 95%CI 1.360 to 1.085) were risk factors for post disaster the teenagers with suicide idea; whether there had been plan to commit suicide as the dependent variable: age (OR=1.099, 95%CI 1.050 to 1.150), the history of being buried in ruin (OR=2.155, 95%CI to 1.104 to 4.205) and changed in family structure after the earthquake (OR=1.495, 95%CI 1.128 to 1.981) were risk factors for post disaster the teenagers with suicide plan; whether took over the action of suicide as the dependent variable: male (OR=1.513, 95%CI 1.122 to 2.039) and changed in family structure after the earthquake (OR=1.555, 95%CI 1.112 to 2.175) were risk factors for post disaster the teenagers with suicide behavior. Conclusion Age and changed in family structure after the earthquake were the risk factors for suicide idea and age was positively correlated with suicidal idea. Age, had the history of being buried in ruin and changed in family structure after the earthquake were the risk factors for suicide plan and age was positively associated with suicide plan. Male and changed in family structure after the earthquake were the risk factors for suicide behavior. Among them, changed in family structure after the earthquake was the common risk factor. So there should be targeted psychological assessment and psychological rehabilitation intervention to avoid the risk of suicide among the teenagers after the disaster.
Objective To evaluate the mental status of survivors after Wenchuan earthquake, so as to provide relevant information for psychological and medical intervention. Methods Demographic data was recorded and the post-traumatic stress disorder (PTSD) Checklist-Civilian Version (PCL-C) was evaluated. The acute stress disorder (ASD) were assessed with the DSM-IV criteria in the survivors from the central earthquake area who are now living in two shelters in Chengdu. Results Among the 780 retrieved questionnaires, 729 baseline registration forms and 450 PCL-C were valid. In the 729 baseline registration forms, male to female ratio was 1:1.31 and the mean age was 36.73±20.82. 9.5% of subjects suffered from physical diseases, 9.7% needed assistance in daily activities, 70.7% were passive and didn’t participate in community activities, 9.1% suffered from severe psychological problems. In the present study, 30.9% of subjects were found to meet the DSM-IV criteria for ASD. 41.3%, 22.2% and 18.4% of subjects had a PCL-C score ≥ 38, ≥ 45 and ≥50, respectively. Consistency check showed there was no significant difference between the screening result of PCL-C score ≥45 and clinical diagnosis (Kappa=0.780, P=0.033). There was significant difference in the age of subjects between ASD and non-ASD groups (Plt;0.05). Conclusion The earthquake survivors suffered from psychological problems after the disaster in the early stage. Thus, in addition to life rescue, we should pay more attention to psychological intervention.
