目的 探讨腹腔液中基质金属蛋白酶1(MMP-1)及其组织抑制剂(TIMP-1)在子宫内膜异位症(EM)发病机制中的作用.方法 双抗体夹心酶联免疫吸附法定量检测44例EM患者(Ⅰ期8例、Ⅱ期2例、Ⅲ期20例、Ⅳ期14例)和30例对照组患者腹腔液中MMP-1、TIMP-1水平.结果 EM患者腹腔液中MMP-1的水平高于对照组(P＜0.05),TIMP-1的水平低于对照组(P＜0.01),Ⅰ～Ⅱ期腹腔液TIMP-1水平高于Ⅲ～Ⅳ期(P＜0.05);对照组腹腔液MMP-1水平与TIMP-1水平呈直线正相关关系;r-AFS分期与腹腔液TIMP-1水平呈负相关关系.结论 腹腔液中MMP-1和TIMP-1可能参与了EM的发生、发展.     

Fertility regulating agents from traditional Chinese medicines

Chinese scientists have capitalized on the rich flora and the ethnomedical experience in China, in their pursuit of fertility regulating agents from natural products. Discoveries range from anti-implantation agents to abortifacient and pregnancy-terminating compounds, as well as a male contraceptive. Chemistry and bioactivity of these compounds and materials are reviewed in this paper, with the hope that further research and collaboration will take place to help solve the problem of population explosion.     

骨保护素/核激活因子受体配体/核激活因子受体(OPG/RANKL/RANK)系统与人工关节置换术后的假体周围骨溶解

人工关节置换术的推广和发展使得多种关节终末期疾病所致的病变获得了良好的临床改善,但术后假体周围骨质溶解这一问题却影响了人工关节远期疗效．长期的研究发现破骨细胞是骨溶解主要原因,而近年研究发现的OPG／RANKL／RANK系统是破骨细胞分化过程中的一个重要信号传导通路,且体内多种激素或因子通过影响骨髓微环境内的OPG／RANKL比率来调节骨代谢．为了给人工关节置换术后骨溶解所致的并发症的防治开辟新的思维,我们综述了OPG／RANKL／RANK系统以及其调控破骨细胞生成、分化对假体周围骨溶解的作用机制．

Flavonoids from Millettia nitida var. hirsutissima with their anticoagulative activities and inhibitory effects on NO production

Two new compounds, (2R)-7,3′-dihydroxy-6,4′-methoxyflavan (1) and (3R)-7,4′-dihydroxy-2′-methoxyisoflavan (2), along with 12 known flavonoids (3–14), were isolated from the vine stems of Millettia nitida var. hirsutissima. The structures of the isolated compounds were elucidated based on spectroscopic analyses and comparison of literature data. All of the isolates were evaluated for their effects on in-vitro anticoagulative assay and on nitric oxide (NO) production in lipopolysaccharide (LPS)-activated RAW264.7 macrophages. As a result, all compounds showed weak antiplatelet aggregation activities and compounds 4, 5, 7, 8 and 9 demonstrated antithrombin activity with a good dose–effect relationship from 5 to 100 μg mL^?1 in rabbit plasma. Compounds 8, 9, 10 and 14 exhibited inhibitory effects on LPS-induced NO production in RAW264.7 macrophages with IC₅₀ values of 4.79 ± 0.20, 8.23 ± 0.35, 5.23 ± 0.11 and 6.30 ± 0.30 μg mL^?1, respectively.     

宫颈环形电切术联合重组人干扰素α-2b栓治疗宫颈上皮内瘤变

目的 探讨宫颈环形电切术(LEEP)联合重组人干扰素α-2b栓治疗宫颈上皮内瘤变(CIN)的临床效果.方法 选择经液基细胞学检查(TCT)、宫颈活检病理检查明确诊断为CIN Ⅰ～Ⅲ级患者82例,均于LEEP治疗前应用导流杂交法检测21种亚型人乳头瘤病毒(HPV DNA),均行LEEP治疗,观察组(41例)为LEEP术后加用重组人干扰素α-2b栓治疗3个疗程患者,分别于治疗后6、12个月行TCT及HPV DNA检测以判断两组的疗效.结果 观察组术后6个月治愈率90.2％,术后12个月治愈率100.0％;对照组术后6个月治愈率43.9％,术后12个月治愈率61.0％;两组6、12个月治愈率差异均有统计学意义(x2=19.93、19.89,均P＜0.05).结论 宫颈环形电切术联合重组人干扰素α-2b栓治疗CIN疗效优于单纯宫颈环形电切术,提高HPV清除率.     

Emerging Roles of Human Prostatic Acid Phosphatase

Prostate cancer is one of the most prevalent non-skin related cancers. It is the second leading cause of cancer deaths among males in most Western countries. If prostate cancer is diagnosed in its early stages, there is a higher probability that it will be completely cured. Prostatic acid phosphatase (PAP) is a non-specific phosphomonoesterase synthesized in prostate epithelial cells and its level proportionally increases with prostate cancer progression. PAP was the biochemical diagnostic mainstay for prostate cancer until the introduction of prostate-specific antigen (PSA) which improved the detection of early-stage prostate cancer and largely displaced PAP. Recently, however, there is a renewed interest in PAP because of its usefulness in prognosticating intermediate to high-risk prostate cancers and its success in the immunotherapy of prostate cancer. Although PAP is believed to be a key regulator of prostate cell growth, its exact role in normal prostate as well as detailed molecular mechanism of PAP regulation is still unclear. Here, many different aspects of PAP in prostate cancer are revisited and its emerging roles in other environment are discussed.
