Predictors of long-term survival in patients with gallbladder cancer

The aim of this study was to examine the predictors of long-term survival (>24 months) in patients with gall bladder cancer. A retrospective review of 117 cases of gall bladder cancer resected between 1989 and 2000. The resections included 80 simple cholecystectomies and 37 extended procedures. Patients with survival >24 months (n=44) were compared with those having survival <24 months (n=73) for 17 prognostic factors. Overall median survival was 16 months with a 5-year survival of 27%. T status (P=.000) and adjuvant chemoradiotherapy (P=.001) were independent predictors of long-term survival. Survival advantage was seen in T3N+ve disease (P=.007) with extended procedures. Complete (R0) resection was attained in 30 patients with a 5-year survival advantage of 30% as compared with incomplete (R1) resection (P=.0002). Adjuvant chemoradiotherapy improved survival in simple cholecystectomy group (P=.0008) but no advantage was seen after extended procedures. Stage III (P=.001) and node-positive disease (P=.0005) had significant benefit with adjuvant therapy. Poor differentiation and vascular invasion were associated with poor long-term survival. R0 resection was associated with prolonged survival. Extended procedures improved survival in patients with T3N+ve disease. Addition of chemoradiotherapy made significant improvement in long-term survival in stage III and node-positive lesions and in patients undergoing simple cholecystectomy. R0 resection predicted long-term survival in gall bladder cancer. T3 N+ve disease had better survival after extended procedures. Adjuvant chemoradiotherapy improved survival in stage III and node-positive disease. Poor differentiation and vascular invasion were adverse predictors of survival.

心理干预对行体外受精病人的影响

体外受精(IVF)治疗对不育夫妇既是一种生理负担又是一种心理负担,在IVF各个时期均表现出心理应激,其中胚胎移植后至妊娠试验前和IVF失败后应激最强,出现负性心理反应,以焦虑、抑郁多见。研究表明,通过心理干预能有效缓解患者的负性心理,并可能提高妊娠率和降低治疗中断率。     

4110例肝炎分型分析

[目的]探讨各型肝炎的感染率。[方法]研究对象为我院住院及门诊患者，共计4110例。采用微粒子酶免分析法（MEIA）及酶联免疫吸附法（ELISA）进行肝炎分型（甲、乙、丙、丁、戊、庚肝）检测。[结果]4110例受检者中，单纯乙肝感染者133例，占3．24％；单纯丙肝感染者134例，占3．26％；单纯戊肝感染者2例，占0．05％；乙肝合并丙肝感染者3例，占0．07％；丙肝合并戊肝感染者1例，占0．02％；HAV、HDV、HGV无一例感染，感染率为0。另外，男性受检者2088人，乙肝感染者88人，占4．21％；丙肝感染者48人，占2．30％；女性受检者2022人，乙肝感染45人，占2．23％；丙肝感染86人，占4．25％。[结论]除丙肝外，各型感染率均低于全国平均感染率，与相关资料报道相差甚远。乙肝及丙肝仍以单纯感染多见。另，本组资料还显示，男性较女性更易感染乙肝病毒，而女性感染丙肝者远远高于男性，对于丙肝感染的性别差异，尚无报道，需进一步探讨。     

老年患者两种浅静脉穿刺方法比较

目的探讨老年患者最佳静脉穿刺方法。方法随机选择400例60岁以上心血管疾病患者,分别采取正面和侧面穿刺方法,分析不同穿刺方法对穿刺成功率、耗时数、疼痛度的影响。结果正面穿刺比侧面穿刺成功率高(P<0.05);正面穿刺较侧面穿刺疼痛度低(P<0.05);正面穿刺耗时数与侧面穿刺相比差异无统计学意义(P>0.05)。结论老年患者血管硬化、弹性下降,适合采用浅静脉正面穿刺。     

广州地区无偿献血人群人类疱疹病毒8型血清流行病学调查

Cause-specific and total mortality in the Canterbury (New Zealand) insulin-treated Diabetic Registry population: a 15-year follow-up study.

AIMS: To establish all-cause and cause-specific death rates, and risk factors for mortality in insulin-treated diabetic individuals living in the province of Canterbury, New Zealand. METHODS: Insulin-treated diabetic subjects (n = 995) on the Canterbury Diabetes Registry were followed up over 15 years and vital status determined. Death rates were standardized and hazard regression was used to model the effects of demographic covariates on relative survival time. RESULTS: There were 419 deaths in 11 226.3 person-years of follow-up with a standardized mortality ratio (SMR) of 2.0 (95% confidence interval (CI) 1.8-2.2). Relative mortality was greatest for the group aged 0-29 years (SMR 3.0 (95% CI 2.4-3.7)). After controlling for diabetes duration and gender, a 10-year increment in age of onset was associated with a 33% decrease in relative hazard (95% CI 29-36%), indicating that excess mortality due to diabetes declines with rising age of onset. After controlling for age of onset and gender, each 10-year increment in duration of diabetes is associated with a 26% decrease in relative hazard (95% CI 24-29%), indicating that with longer survival the mortality hazard approaches the general population hazard. Relative mortalities were increased for cardiovascular, renal and respiratory disease, but not malignancy. Relative mortality from acute metabolic complications was increased in the subgroup with age of onset of diabetes < 30 years and requiring insulin within 1 year of diagnosis. CONCLUSIONS: Mortality rates are high for insulin-treated diabetic individuals relative to the general population.     

Mycophenolate Mofetil Use Is Associated with Decreased Risk of Late Acute Rejection in Adult Liver Transplant Recipients

Mycophenolate mofetil (MMF) used in a triple-drug regimen has been shown to decrease acute rejection rates, compared to a double-drug regimen. The impact of MMF on late acute rejection (LAR) episodes has not been well described. To investigate the risk of LAR (rejection > or = 6 months post-transplantation) data from the Scientific Registry of Transplant Recipients (SRTR) were used. We studied adult primary liver transplant recipients transplanted between June 1, 1995, and April 30, 2004, with hepatitis C virus (HCV) (n = 3356), hepatitis B virus (HBV) (n = 550) or a nonviral (n = 5740) primary cause of liver disease who were recorded as receiving continuous 3-(MMF + Tacro + steroids) versus 2-drug (Tacro + steroids) therapy for at least 6 months immediately post transplantation. Kaplan-Meier analysis showed significantly lower LAR rates 4 years post-transplant in 3- versus 2-drug HCV, HBV and nonviral disease patients. Multivariate regression confirmed 3- versus 2-drug therapy to be associated with a decreased risk of LAR. Late graft survival was significantly lower at 4 years post-transplant for patients with LAR 6-12 months post-transplantation versus patients with early rejection (78.0% vs. 87.0%, p < 0.001) and no rejection (88.1%, p < 0.001). Three-drug versus 2-drug therapy for a minimum of 6 months may offer a better treatment strategy to avoid the consequences and expense of LAR episodes.
