双侧内囊前肢毁损术治疗难治性强迫症疗效及随访研究

目的　对难治性强迫症进行双侧内囊前肢毁损术治疗 ,评定手术疗效并进行 2年随访 ,以进一步探索脑外科手术对难治性强迫症的疗效 ,并探讨手术治疗的良好适应症。方法　对 2 8例难治性强迫症患者进行双侧内囊前肢毁损术治疗 ,并分别在手术前、手术后二周、手术后三月、手术后六月、手术后一年、手术后二年进行Y BOCS、HAMA、HAMD量表评定及术后疗效评定。结果　 (1)强迫症患者手术后各期Y BOCS评分、HAMA评分与手术前比较均下降 ,有极显著差异 (P <0 .0 0 1) ;(2 )手术后各期Y BOCS的强迫思维评分均有明显下降 (P <0 .0 0 1) ,强迫行为在手术后 1年和 2年 ,与手术前比较无明显改变 (P >0 .0 5 ) ;(3)手术后 2年的总有效率为 5 3.5 % ,明显低于手术后 3月的总有效率 (P <0 .0 1)。结论　采用双侧内囊毁损术有相当的治疗效果 ,对于难治性强迫症患者可作为一种补充治疗手段 ;手术治疗对强迫行为的长期疗效较差 ,以严重的强迫思维为主的难治性强迫症患者为手术更好的适应症。     

Laryngeal tuberculosis: a review of 26 cases.

OBJECTIVES: To review the clinical characteristics of laryngeal tuberculosis. STUDY DESIGN: Retrospective case series. SUBJECTS AND METHODS: Medical records of 26 histopathology-confirmed cases in a tertiary medical center from 1992 to 2006. RESULTS: The female patients were significantly younger than male patients. Hoarseness is the most common symptom (84.6%) because true vocal fold is most commonly involved (80.8%). Infection usually involves unilateral (66.7%) and right-side larynx but multiple subsites of the larynx (57.7%). The appearance of the affected larynx may have mixed features and change before diagnosis. Laryngeal tuberculosis is usually misdiagnosed as laryngeal cancer, especially in patients with malignant signs such as enlarged cervical lymph nodes and vocal fold immobility. Chest film is better than sputum examinations for screening. CONCLUSION: We should be especially alert about TB infection when facing young female patients with unusual laryngeal lesions. Extensive laser excision before diagnosis should be avoided because after antituberculous treatment, prognosis is usually good and vocal fold immobility could be reversible.     

表皮生长因子及其受体与流产关系的探讨

采用放射免疫竞争抑制饱和分析法，检测４７例难免流产患者，６５例人工流产及２０例健康非孕妇女血清表皮生长因子（ＥＧＦ）水平；同时采用免疫组织化学法检测流产者胚胎组织中表皮生长因子受体（ＥＧＦＲ）表达程度。结果：人工流产组血清ＥＧＦ水平高于自然流产及非孕妇女，而自然流产与非孕妇女差异无显著性；胚胎组织中ＥＧＦＲ阳性表达率人工流产组明显高于自然流产组。提示：ＥＧＦ通过与其受体结合对妊娠维持、胚胎及胎儿的     

小切口胆囊切除术108例临床观察

本文报告腹部切口５－８ｃｍ的小切口胆囊切除术１０８例，与同期大切口胆囊切除术相比，具有创伤较小、恢复较快、并发症少、切口疤痕小的优点，虽不如腹腔镜胆囊切除术（ＬＣ）的疼痛轻、恢复快，但并症比ＬＣ少，只要适应症选择得当，在术者的经验和技术较成熟的情况下，不昔为一种可供选择的方法。     

Inhibitory effect of glycyrrhiza uralensis fish and chelidonium majus L on gastrocarcinogenesis induced by N-methyl-N′-nitron-N-nitrosoguanidine

In order to investigate the antagonistic effect of Glycyrrhiza Uralensis Fish (GUF) and Chelidonium maJus L (CML) on gastrccarcinogenesis induced by MNNG in Wastar rats, we treated the rats with MNNG alone (group 1) and with MNNG plus GUF and CML (group 2 and 3) respectively. The incidence of infiltrating adenocarcinoma of the glandular stomach and duodenum in group 2 was significantly lower than that in group 1 (26.7% vs. 67.8%). The differentiation and aggressivenees of carcinomas occured in group 2 were much better and mild than those in group 1. Present study also demonstrated that the inhibitory effect of CML on proliferation of human stomach carcinoma cell line MGC-803 was very remarkable; in addition, GUF and CML were able to antagonise the mutagenic activation of MNNG. These results suggest that GUF and CML may be empoyed in prevention of gastric carcinoma.     

Immunoregulatory effects of phospholipase A2 (PLA2) on the proliferation of human lymphocytes

Extracellular phospholipase A2 (PLA2) is a proinflammatory enzyme found especially in the inflammatory exudate to modulate blood flow to areas of antigen stimulation. In this study we found that PLA2 exerted a biphasic effect on the proliferation of phytohemagglutinin (PHA)-stimulated human mononuclear cells (PHA MNC). At low concentrations range from 0.001 to 1 U/ml, PLA2 enhanced the proliferation of PHA MNC (maximal increase was 37.0 +/- 5.67%). Conversely, at concentrations over 10 U/ml, PLA2 markedly suppressed the PHA-induced MNC proliferation (maximal decrease was 88.86 +/- 2.89%). PLA2 was non-toxic to lymphocytes after three days culture, unless the concentration was higher than 100 U/ml. The membrane polarization of PHA-stimulated lymphocytes was also increased by PLA2 at a low concentration. In addition, PLA2 displayed a similar effect on the proliferation of streptokinase-streptodornase (SK/SD) or allogeneic cell stimulated lymphocytes. The change of lymphocyte proliferation by PLA2, was parallel to the change of percentage of helper T cells. Furthermore--a CD4-rich population was proved more susceptible to PLA2 effect than a CD8-rich population. Para-bromophenacyl bromide (pBPB), an irreversible inhibitor of PLA2, abrogated the biphasic effect of PLA2 on PHA MNC proliferation. These results suggest that PLA2 plays a regulatory role on immune reactions by modulating the percentage of helper T cells.
