肾功能损伤分级系统在成人心脏术后的应用

Objective The aim of this study was to evaluate of adilty of two acute renal failure-specific scoring systenms (the classification by Bellome et al and the AKIN criteria) for predicting hospital mortality after cardiac surgery in adult patients. Methods Between October 1 st 2006 to Decemjber 31 st 2006, 509 adult patients who ungerwent coronary artery bypass grafting (CABG) and/ or valve operation were enrolled in this study. The medical data collection included gender, age, types of operation, perioperative he- modynamic parameters, urine output, biochemical parameters and outcome. Renal function was assessed daily according to the classi- ficatinn by Bellomo and the AKIN criteria, respectively. As references, Acure Physiology and Chronic Health Evaluation(APACHE) Ⅱ and Sepsis-related Organ Failure Assessment (SOFA) score were also calculated. Resuits Three hundred and forty-one patients were male (67.0%), and 168 were female (33.0%), mean age was (56.2±12.0) years old. Tnree hundred and nine patieats un- derwent CABG, 182 underwent valve operation and 18 underwent CABG plus valve operation, Mean duration of ventilation support was (20.4±17.7) houra, and the ICU stay was (1.4±1.0) days. Postoperative hospital stay was (13.8±9.1) days. According to the classification by Bellomo., the highest in-hospital mortality was 52.9% in ARFS group. Mahiplicatinn of in-hospital morality rate was abserved (X2 for trend, P<0.01) in 0.4% (non-ARF), 1.2% (stage 1), 12.0% (stal～ 2) and 32.4% (stage 3) of pa- tients based on the AKIN criteria. By applying the area under the receiver operating characteristic ourve, the classification by Bellomo and the AKIN criteria had good discriminative power. Furthering, multivariate logistic regression analysis verified that the Odds Ratio of the AKIN criteria was 5.478 (P =0.028, 95% Confidence Interval 1.027- 24.856), after adjusting for gender and age. Con- clusion Analytical data confinned good discriminative power of both the AKIN criteria and the classification by Bellomo for predicting hospital mortality of adult postoperative patient with ARF.

MUC-1基因在胃癌和外周血中的表达及临床意义

目的：检测胃癌MUC－1的表达情况及其与临床分期和转移的相关性。方法：应用逆转录聚合酶链反应（RT－PCR）和免疫组化方法检测胃癌活检标本和外周血中MUC－1基因和蛋白的表达水平。结果：在56例胃癌病例中MUC－1 mRNA阳性表达率为48．2％，MUC－1蛋白阳性表达率为53．6％，临床分期中I和II期病人阳性表达率MUC－1 RNA为33．3％，MUC－1蛋白为40％，而-Ⅲ期病人则分别高达65．4％和69．2％，二者差异有显著性意义（P＜0．05），在淋巴结转移的患者中外周血的癌细胞MUC－1高表达，阳性率为73％，结论：MUC－1是一种较好反映胃癌恶性程度和转移性的肿瘤标志物。

Ⅱ型浮膝损伤术后膝关节功能康复

目的:总结Ⅱ型浮膝损伤患者的治疗方法和手术后膝关节功能康复疗效。方法:回顾分析经治的68例患者,男57例,女11例;年龄17~60岁。68例共74侧肢体的Ⅱ型浮膝损伤-膝关节内骨折病例,其中双侧肢体Ⅱ型浮膝骨折6例。根据患者骨折类型、是否存在开放性损伤、软组织损伤程度分别采用内固定(髓内钉、解剖钢板)和支架外固定方法,术后均采用统一、系统的康复治疗。术后对治疗结果采用Karlstrom和Olerud的浮膝损伤治疗标准进行评价;使用χ2检验对两种固定方法治疗后膝关节功能康复效果差别进行显著性分析。结果:所有病例均得到1~4年的随访,平均24个月。内固定组优良率64.29%,支架外固定组优良率80.43%。内固定组与支架外固定组比较,膝关节活动受限度指标有统计学差异(P<0.05),说明Ⅱ型浮膝损伤应当注重对关节内骨折的复位和减少对膝关节周围软组织的破坏。结论:①早期功能恢复期支架组优于内固定组;②牵引后及术后早期系统的康复治疗有利于膝关节功能恢复和减少并发症;③伸膝功能锻炼应当在牵引治疗后即开始,膝关节屈伸功能锻炼在手术后3d进行。     

Mifepristone-induced abortion and birth weight in the first subsequent pregnancy.

OBJECTIVES: To assess the effect of a medically induced abortion (MA) on birth weight in the first subsequent pregnancy. METHODS: Pregnant women who had had a MA, a surgical abortion (SA), or primigravidas with no history of abortion (NA), were recruited for a prospective cohort study between July 1998 and February 2001. The sample for the present analysis included 12995 singleton live births at term. RESULTS: The overall incidence rate of low birth weight (LBW) was 1.0%. The rates of LBW in the MA, SA, and NA groups were 1.0%, 0.9%, and 1.2, respectively. There were no significant differences in LBW rates between the MA and SA groups, neither between the MA and NA. Logistic regression analysis was used to estimate the effects of MA on birth weight, and we found no relationship between risk of LBW and MA. CONCLUSIONS: We did not find a statistically significant relationship between a history of one medically induced abortion and LBW for the first subsequent term pregnancy.
