脊柱复合性损伤的救治风险与早期治疗

目的评估脊柱复合性损伤的特点和救治风险,探讨风险控制与最佳治疗的方法。方法采用AIS、ISS、TRISS及APACHEⅡ等评分方法对273例脊柱复合性损伤患者进行定量评价与救治分类,并依据伤后的损伤分级、参数评定及计量评分等指标进行量化分析和统计处理。结果颈椎合并伤115例,胸椎合并伤141例,胸腰椎合并伤294例,腰骶椎合并伤181例;患者的救治风险和脊椎伤的治疗选择或手术时机与其合并伤的解剖伤势及由此所构成的整体伤情密切相关(P<0.01或<0.05);高风险性伤员往往综合伤势严重,生存概率(Ps)趋低,并发症和死亡率高(P<0.01或<0.05)。结论脊柱脊髓损伤常合并有严重的多发伤,高危伤情不仅可增加其救治风险和脊柱伤的处理难度,且还易于丧失手术最佳时机。分类救治对伤员的风险控制和脊柱伤的专科治疗是有益的。

Testing for familial aggregation of functional traits

In a genetic epidemiology study of a trait, prior to collecting genotype data the foremost task is to test for familial aggregation and examine heritability. Recently, functional traits have drawn attentions from investigators. Here, to test for familial aggregation of a functional trait in the family studies, a test constructed based on the leading functional principal component of heritability, which is a summary measure of temporal genetic variation in a functional trait, is proposed. The p‐value of the test can be approximated by a permutation procedure given the family structure. The asymptotic distribution of the test statistic is derived. Simulations are carried out to examine the size and the power of the test. The proposed methods are applied to the total cholesterol data in the Framingham Heart Study.

9 Survivin反义寡核苷酸对人肝癌细胞的抑制作用

目的:探讨survivin反义寡核苷酸（ASODN）对人肝癌细胞HepG2的抑制作用。方法:采用免疫组织化学法检测肝细胞癌（HCC）组织中survivin的表达。采用脂质体介导survivin ASODN体外转染人肝癌细胞株HepG2，Western blot检测细胞survivin蛋白的表达，FCM检测细胞的凋亡率，观察细胞在软琼脂中的集落形成能力。建立人肝癌裸鼠皮下移植瘤模型，观察survivin ASODN的体内抑癌作用。 结果:（1）肝癌组织中survivin表达阳性率为75.8％(25/33)，明显高于癌旁组织和正常肝组织(P<0.01);（2）survivin ASODN体外转染可明显下调HepG2细胞survivin蛋白表达，ASODN组HepG2细胞凋亡率明显高于空白对照组和SODN组(P<0.01)，ASODN组HepG2细胞在软琼脂中形成的集落数目明显少于空白对照组和SODN组(P<0.01);（3）ASODN组瘤体生长速度较空白对照组和SODN组明显减慢(P<0.01)，ASODN组瘤体重量较空白对照组和SODN组明显减轻(P<0.05)。结论:Survivin在HCC组织中高表达;survivin ASODN可以诱导HepG2细胞凋亡，在体外实验和动物实验中对HepG2细胞生长都有抑制作用。     

Decision analysis model of incisional hernia after open abdominal surgery

Background The incidence rate of incisional hernias after open surgery has been reported to be higher than that of port site hernias after laparoscopic surgery. No studies have compared the costs for the health care system in treating those two types of hernia. Methods A systematic review was conducted to obtain the baseline data, and a decision analysis model was created to simulate the occurrence and recurrence of incisional and port site hernias. Results The overall risk of having incisional hernias was eight-times higher than that of having port site hernias (7.4% vs 0.9%). A cost savings of ￡93 per patient can be generated for the health care system in the UK. Similar results were obtained for Germany, Italy and France. Conclusions The additional treatment costs for incisional hernia should be taken into account when the costs of a surgery performed by open approach are compared with by laparoscopy.     

精神病住院病例45年抽样分析

目的　对 4 5年来本院住院精神病病例的病种、分型、治疗措施和疗效等作一简要的回顾总结。方法　将自 195 4年 5月到 1999年 9月入院的病人 ,按首次入院日期每隔五年连续抽取 10 0份病例 ,扼要摘录有关内容进行登记、统计、分析。结果　男女病例数大致相仿。平均年龄 (31 9± 12 1)岁 ,平均住院日期 (6 2 1± 36 3)月 ,遗传史阳性率占 2 3 4 % ,精神分裂症占 5 4 % ,心境障碍占 13% ,癔症占 12 5 % ,电休克应用例数自 195 4年的 4 1 5 %降到 1999年的 2 % ,胰岛素治疗自 195 4年的 4 8%逐渐降低到 1989年 4 % ,1999年后为零。药物治疗西药自 5 7年的一种 (氯丙嗪 )增加到 1999年的 2 0余种。中药治疗经过 195 9年和 1970年的两个高潮 ,新针治疗自 196 9年至 1989年亦告结束。两者均无明显疗效。精神分裂症和心境障碍的显效率平均为 70 6 %和 90 8%。但均有评价过高之嫌。结论　根据我院的实践 ,传统的中药方剂、单味草药和“新针”治疗对主要精神病无明显疗效 ,195 9年后住院病人的疗效有明显的提高 ,愈来愈多的抗精神病药和取代了原有的胰岛素休克和电休克治疗。     

Program Directors' Views of the Effect of Managed Care on Substance Abuse Programs in Southern California

This article reports the results of semi-structured interviews with substance abuse treatment (SAT) program directors (PDs) regarding the ways SAT is being influenced by managed care (MC), plans for future SAT, and strategies for decreasing costs of care. It compares findings to an earlier survey of 50 SAT PDs.

Interviews were conducted in 20 SAT programs to gather information about treatment delivery since the advent of MC, including PD responsibilities, funding source, treatment intensity, location, duration, and methods of treatment. Open-ended responses were used to gather information about current and future plans in providing SAT, and awareness of new types of treatment being planned by organizations impacted by MC.

PDs reported changes in SAT secondary to MC such as decreased treatment length, limiting of inpatient and outpatient services, and delayed treatment secondary to benefit determination. Political and economic constraints were seen as barriers to providing adequate and effective services. SAT being subsumed by mental health was viewed as problematic along with an emerging split between alcohol abuse and drug treatment. A positive emerging treatment trend was the development of targeted programs for special need groups.

PDs revealed a variety of strategies that have promoted necessary adaptations to economic and political influences within the structure of managed behavioral care. Strategies such as varying treatment length, modality, and subspecialty care reflected necessary adaptations to diverse market needs.

Managed care continues to have a tremendous impact on the delivery of SAT services. While MC has helped to contain costs, negative outcomes are decreased availability of appropriate care and overtaxing of units that have survived MC cut backs. However, special need programs have allowed SAT programs to specialize, expand, and even flourish in today's competitive SAT market. Interviews with PDs reinforced the need for maintaining quality and diversified SAT services in today's MC environment.
