“抑肝纤”对大鼠实验免疫损伤性肝纤维化阻断作用的研究

目的本研究利用人血白蛋白免疫损伤Ｗｉｓｔｅｒ大鼠造成肝纤维化模型，以观察“抑肝纤”对大鼠肝纤维化的阻断作用。方法将不同浓度中药“抑肝纤”用于治疗组并与模型组和对照组进行对比，综合分析血清肝纤维化指标、肝组织病理改变、肝组织胶原纤维和网状纤维病理图像定量分析等结果。结果治疗组血清肝纤维化指标（ＰＣⅢ、ＨＡ、ＬＮ）均低于模型组，接近正常组，差异有显著性（Ｐ＜０．００１或Ｐ＜０．０５）。光镜下肝组织病理变化，肝组织中胶原纤维和网状纤维病理图像定量分析结果治疗组优与模型组，尤以低浓度组更为明显（Ｐ＜０．００５或Ｐ＜０．０５）。结论研究结果表明，中药“抑肝纤”如能早期应用，可有效地阻断或延缓实验鼠肝纤维化的发生     

Tissue Inhibitor of Metalloproteinase-1 Concentrations are Attenuated in Peritoneal Fluid and Sera of Women with Endometriosis and Restored in Sera by Gonadotropin-Releasing Hormone Agonist Therapy

Objective: To establish tissue inhibitor of metalloproteinase-1 (TIMP-1) concentrations in peritoneal fluid (PF) and sera of women with endometriosis and compare them to disease-free controls.

Design: Prospective randomized study.

Setting: Academic medical center.

Patient(s): Women with laparoscopically documented endometriosis and disease-free women of reproductive age.

Intervention(s): Peritoneal fluid and sera were collected, and some women received gonadotropin-releasing hormone agonist (GnRH-a) therapy for endometriosis.

Main Outcome Measure(s): Peritoneal fluid and sera TIMP-1 concentrations were measured with a specific RIA.

Result(s): The TIMP-1 concentrations were significantly lower in PF and sera of women with endometriosis compared with disease-free women. The GnRH-a therapy restored serum TIMP-1 concentrations.

Conclusion(s): Aberrant expression and localization of TIMP-1 may derange the proteolytic milieu of the peritoneal cavity and contribute to the etiology and underlying physiologic sequelae associated with endometriosis. Measurement of TIMP-1 in serum may aid in diagnosing endometriosis and assist with monitoring treatment efficacy in women with this disease.

利用"分层法"评价中药复杂体系药效时有关权重设立的讨论

本文讨论了以分层法进行中药药效评价时权重设立的问题，主要由以下几部分组成：1．建立递阶层次结构；2．构造两两比较判断矩阵；3．计算单一准则下元素的相对权重；4．计算各层元素的组合权重。由于中药作用具有多途径、多靶点的特性，因此评价过程中权重的设立就占有重要位置。它直接影响对被评价对象药效作用的评判。全面解决中药作用多途径、多靶点药效学评价的数学方法，客观量化的评价中药的综合药效，是中药现代化进程中一个值得研讨的命题。     

男性胰腺实性-假乳头状瘤2例临床病理观察

目的探讨胰腺实性-假乳头状瘤(SPT)的临床病理特征及了解分子病理学研究进展。方法2例SPT分别作HE、PAS、免疫组织化学(S—P法)染色观察。结果2例SPT男性患者均有腹部包块及腹痛症状。术后均无复发。肿块体积较大，囊实性相间。镜下瘤细胞围绕纤维血管形成特征性的假乳头结构，并可见退行性变、出血和泡沫细胞。免疫组化结果：2例AACT、ACT、Cga和Syn均为阳性，PR、ER、Ck和Ins均为阴性，1例Vim为阳性。结论胰腺SPT为具有独特临床病理特征的低度恶性肿瘤。

Validating the EQ-5D with time trade off for the German population

The aim of this survey study was to derive the societal values of the general public for the EuroQol EQ-5D. Using the same protocol as previously used in the United Kingdom, we compared the German values with the British. In face-to-face interviews a sample of 339 individuals in northern Germany valued 15 different health states from a sample of 36 states. Values were derived using the York MVH protocol for time trade-off (TTO) and a visual analogue scale (VAS). Values for all 243 health states of the EQ-5D were estimated by a regression model. The VAS values revealed close a resemblance to the British VAS results. German TTO values were higher than the British. This was especially the case for the worse health states. The results suggest that the TTO values are more related to national variables than values derived by VAS. The use of the TTO values of this investigation makes it possible to anticipate these cultural differences in studies carried out in Germany.
