青蒿素对ApoE-/-基因敲除小鼠动脉粥样硬化的影响

目的探讨青蒿素对ApoE-/-基因敲除小鼠动脉粥样硬化以及炎症因子的影响。方法将20只ApoE-/-基因敲除小鼠分为青蒿素组和PBS处理组,每组10只,经高脂喂养8周,与对照组小鼠(C57BL/6J标准饮食小鼠,10只)比较,通过血管大体油红O染色评价斑块面积;HE染色观察病变形态及血浆中炎症因子的变化。结果与对照组比较,PBS处理组及青蒿素组均可见动脉硬化斑块,炎症因子水平升高。青蒿素组的动脉硬化程度及炎症因子水平均明显低于PBS处理组。结论青蒿素可以改善ApoE-/-基因敲除小鼠动脉粥样硬化进展。     

河南省新报告HIV感染者中丙型肝炎病毒感染状况及其影响因素分析

目的 了解河南省新报告HIV感染者中丙型肝炎病毒（HCV）感染情况及其相关影响因素。方法 对2012年7月1日至2013年6月30日河南省所有新确证上报的HIV-1感染者进行信息整理、HIV-1 BED新发感染检测和HCV抗体检测。结果 河南省该期间新确证上报2 049例HIV-1感染者中HCV抗体阳性率为14.87%（271/1 887），BED阳性比例（新发感染比例）为26.34%（497/1 887）。新发HIV-1感染者中HCV抗体阳性率较既往HIV-1感染者低，20～39岁组HIV-1感染者的HCV抗体阳性率较其他年龄组低，个别地区HIV-1感染者的HCV抗体阳性率较高，经注射吸毒感染HIV-1者中HCV抗体阳性率较高。结论 新发感染、年龄、传播途径和地区分布是河南省新报告HIV-1感染者中HCV感染率的影响因素，应有针对性地开展此人群的丙型肝炎防治工作。     

S100A14, a mediator of epithelial-mesenchymal transition,regulates proliferation,migration and invasion of human cervical cancer cells

S100A14 is an EF-hand calcium-binding protein that has been reported to exert its biological effects on different types of cells. However, the potential clinical significance and biological functions of S100A14 in cervical cancer has not yet been clarified. In this study, we firstly examined the correlation between S100A14 expression and clinical-pathological parameters in cervical cancers. Next, we observed the effect of S100A14 on cell cycle progression, cell proliferation, migration and invasion by employing lentiviral-mediated overexpression and knockdown of S100A14 in cervical cancer cells. Furthermore, we investigated the underlying mechanism of S100A14 affecting cell migration and invasion. Immunohistochemistry analysis demonstrated that S100A14 expression was associated with the International Federation of Gynecology and Obstetrics (FIGO) stage (P = 0.025) and lymph node (LN) metastasis (P = 0.001). Functional assays showed that S100A14 overexpression increased the proportion of G2/M phase, promoted cell proliferation, migration, and invasion, whereas S100A14 knockdown exhibited adverse effect on above properties. Mechanistic investigation demonstrated that S100A14 can act as a mediator of epithelial-mesenchymal transition (EMT). And overexpression of S100A14 increased expression of N-cadherin and Vimentin while decreased expression of E-cadherin. The opposite results were observed in S100A14-silenced cells. Taken together, our data indicate that S100A14 has a crucial role in cervical cancer progression. This study significantly increases our understanding of S100A14 functional roles in cervical cancer, which may lead to the development of a novel therapeutic target for cervical cancer.     

大蒜素用于非侵袭性真菌性鼻窦炎术后局部冲洗疗效分析

目的评价大蒜素术后局部冲洗对非侵袭性真菌性鼻窦炎的疗效。方法将90例患者随机分为3组,每组30例,分别使用生理盐水、5%碳酸氢钠液+0.1%氟康唑、大蒜素溶液等对非侵袭性真菌性鼻窦炎术后患者进行局部浴洗,随访6个月,比较其有效率。结果大蒜素组与氟康唑组有效率比较差异无统计学意义(P>0.05),但都优于生理盐水组(P<0.05)。结论大蒜素用于非侵袭性真菌性鼻窦炎患者术后局部浴洗有较好疗效。     

小胃肠间质瘤手术方式的选择

目的：探讨小胃肠道间质瘤(gastrointestinal stromal tumor，GIST)的生物学特性及不同手术方式下的复发率 及并发症发生率，以协助其手术方式的选择。方法：回顾性分析中南大学湘雅医院2009年1月到2015年12月经病理科 确诊为GIST且肿瘤直径<2 cm的78例原发性局限性GIST患者(共79处病灶)的临床及病理资料，并分析小GIST手术治 疗的并发症发生情况及术后复发情况。结果：小GIST患者中男:女=1:1.69，初诊的中位年龄为49岁，中老年多见。病 灶最多见于胃，其次是食管、小肠，结直肠最少。60.3%(47/78)患者出现腹痛腹胀，7.7%(6/78)有黑便或便血症状。 98.7%(78/79)小GIST核分裂象≤5/50 HPF。免疫组织化学示CD117阳性率98.7%，CD34阳性率86.1%， DOG-1阳性率 82.3%，actin-平阳性率31.6%，S-100阳性率24.1%。手术切除后共3例患者出现并发症，其中1例为内镜治疗患者，2例 为传统手术治疗患者；随访过程中共2例复发，均为传统手术切除患者。传统手术治疗与内镜治疗的术后并发症发生 率及复发率差异均无统计学意义(P>0.05)。结论：小GIST恶性潜能低，复发转移率低，生物学行为偏良性。传统手术 治疗与内镜治疗均安全有效，但内镜治疗相对有费用较低、住院时间较短及创伤较小等优点，因此在内镜操作技术 较为成熟的地方，内镜治疗不失为小GIST根治性切除的首选方法。
