肠道间质瘤10例临床分析

目的:探讨肠道间质瘤的临床表现、病理类型、诊断及治疗措施。方法:回顾性总结长海医院1991年至2001年经手术治疗并经病理证实了的10例病例。结果:主要表现为:阵发性腹痛、腹胀、消化不良、便血、腹部或直肠包块。病理类型:良性间质瘤2例、恶性间质瘤8例。结论:肠道间质瘤表现无特殊性、易误诊,内镜和X线钡灌肠检查是术前常用的方法,腹部核素扫描、超长型电子小肠镜可提高诊断率。治疗上应采取以手术为主的综合治疗。     

烧伤后手指瘢痕挛缩畸形综合治疗的临床研究

目的通过比较手术结合康复综合治疗方案与常规治疗方案对烧伤后手指瘢痕挛缩畸形的治疗效果,探讨综合治疗的优越性及经验。方法1999年6月~2004年6月,共56例烧伤后手指瘢痕挛缩畸形患者纳入试验。综合治疗组(A组)28例,男20例,女8例;年龄14~47岁,平均31岁;患手共47只129指,以手术结合系统康复治疗。常规治疗组(B组)28例,男17例,女11例;年龄18~51岁,平均30岁;患手共42只107指,采用常规手术,术后仅作简单的康复性锻炼指导,由患者在院外自己完成功能锻炼。采用Swanson法对患指运动功能进行评定,九孔柱试验法对患手整体运动功能进行评定,比较两组患者治疗前后手指和手整体运动功能的差异。结果A组患者术后均获随访12~19个月,B组患者均获随访13~20个月。治疗前A组患指的强直失能指数(indexofankylosis,IA)值为82%±20%,B组为78%±17%;治疗后A组为45%±13%,B组为52%±14%;治疗前后A组IA差值为37%±15%,B组为26%±15%,两组比较差异有统计学意义(P<0.05)。治疗前A组九孔柱测量值28.34±5.62s,B组为27.47±5.78s;治疗后A组为20.73±4.25s,B组为21.86±4.12s;治疗前后A组九孔柱测量差值为7.61±2.27s,B组为5.61±2.94s,两组比较差异有统计学意义(P<0.05)。结论烧伤后手指瘢痕挛缩畸形采用手术结合康复综合治疗的效果明显优于常规治疗,值得推广。     

Islet Xenotransplantation: Are We Really Ready for Clinical Trials?

Four clinical trials of porcine islet transplantation have been reported, and there are verbal reports that clinical trials on much larger scales are continuing in centers in China and Russia. The four reported trials are briefly reviewed and, in the light of the present status of experimental islet xenotransplantation, consideration is given to whether such trials are currently justified. The Ethics Committee of the International Xenotransplantation Association has (1) emphasized the need for encouraging studies in non-human primates before clinical trials should be undertaken, (2) mandatory monitoring for the transfer of porcine microorganisms, and (3) careful regulation and oversight by recognized bodies. Other aspects of the topic, such as the need for informed consent, are briefly discussed. We conclude that, at the present time, more data documenting convincing efficacy, focused on clinically applicable immunosuppressive regimens, are needed to justify the initiation of closely monitored clinical trials. A clinical trial may then be justified even though the potential risk to the patients, and possibly for society, will not be zero.     

KGF在乳腺癌的表达与临床意义

目的:探讨KGF蛋白在人乳腺癌的表达与意义,与临床病理因素及生物学指标的相关性。方法: 采用免疫组化方法检测KGF在63例乳腺癌组织中的表达,并与正常乳腺组织对照。结果:63例乳腺癌组织中34例肿瘤细胞表达KGF(54．0％),正常乳腺上皮细胞未表达(P<0．01),在乳腺癌间质细胞和正常乳腺组织间质细胞表达率分别为34．9％和16．7％(P>0.05)。其在肿瘤细胞中的表达与低分化相关,与ER、PR呈负相关,与Ki-67呈正相关,与Ki-67的协同表达与淋巴结转移正相关。结论: KGF在乳腺癌肿瘤细胞的表达可能促进乳腺癌的发生发展,并且与低分化、预后不良有关。     

间断纵行缝扎硬化注射治疗直肠黏膜内脱垂68例临床分析

目的:观察和评价间断纵行缝扎硬化注射治疗直肠黏膜内脱垂的临床疗效。方法:将68例直肠黏膜内脱垂患者随机分成两组,治疗组(36例)采用经间断纵行缝扎硬化注射治疗,对照组(32例)采用单纯硬化注射治疗。并对临床资料进行分析总结。结果:术后3个月随访,治疗组与对照组的症状、体征总得分比较,治疗组均优于对照组。结论:纵行缝扎硬化注射治疗后症状消除快,近远期疗效佳。     

Ritanserin in the treatment of alcohol dependence – a multi-center clinical trial

Four hundred and twenty-three alcohol dependent subjects were enrolled into a 12-week randomized, double-blind, placebo-controlled study to determine the safety and efficacy of the 5-HT₂ receptor antagonist, ritanserin (2.5 mg/day or 5 mg/day), in reducing alcohol intake and craving. All subjects received 1 week of single-blind placebo prior to randomization into the 11-week double-blind phase. Additionally, all subjects received weekly individual sessions of manual-guided cognitive-behavioral therapy. Comparing the single-blind period with endpoint, there was approximately a 23% reduction in drinks/day; 34% fall in the total number of drinking days/week; 22% decrease in drinks/drinking day; and a 37% diminution in alcohol craving for all treatment groups. All treatment groups experienced a beneficial clinical outcome as assessed by the Clinical Global Impression Scale. There was, however, no significant difference between treatment groups on any of these measures of alcohol drinking, craving, or clinical outcome. Subjects were of relatively high social functioning at baseline, and this did not change significantly during treatment. Treatment groups did not differ significantly on either medication compliance or reported adverse events. Ritanserin treatment was associated with a dose-related prolongation of subjects’ QTc interval recording on the electrocardiogram. These results suggest that alcohol dependent subjects can show marked clinical improvement within a structured alcohol treatment program. These findings do not support an important role for ritanserin in the treatment of alcohol dependence. Received: 30 April 1996/Final version: 3 July 1996

Comparison of gas-liquid chromatography and EMIT assay for serum valproic acid

We describe a simple direct extraction method for the gas-liquid chromatography determination of serum valproic acid. The working range for the assay is 2-180 mg/L and our within-run precision was 5.8 and 4.3% at the 40 and 90 mg/L concentrations respectively. Hemolyzed and lipemic sera as well as samples from patients with hyperbilirubinemia and from patients with decreased renal function were put through the assay and no interfering peaks were noted. Interference occurred when teflon-lined screw caps were used during the extraction step. The method was proven to be accurate by linear regression analysis of samples containing weighed-in amounts of valproic acid. The above assay was compared to an enzyme immunoassay technique (EMIT). The working range for the latter is 10-150 mg/L and the with-run precision was 10.8 and 5.9% and 90 mg/L concentration respectively. Samples were run by both the gas-liquid chromatograph and enzyme immunoassay methods and gave very similar results over the range 16-139 mg/L.
