2016~2018年苏州市育龄妇女HPV感染因素分析

目的 调查苏州市育龄妇女人乳头状瘤病毒（HPV）感染情况及其影响因素。方法 以整群抽样方式选取2016年7月~2018年12月苏州市育龄妇女4275例为研究对象,进行HPV和TCT检查,并填写调查问卷,了解HPV感染情况。结果 4275例孕妇中存在HPV感染者964例（22.55%）;HPV发生与年龄、职业、在苏时间、文化程度、每周性生活频率、性伴侣数、避孕方式、性传播疾病史、CIN、吸烟等因素有关,差异有统计学意义（P＜0.05）;Logistic回归分析显示:文化程度、性生活频率、避孕方式、吸烟、年龄、职业是苏州市育龄妇女HPV发生的独立危险因素（P＜0.05）。结论 苏州市育龄妇女HPV感染率较高,文化程度、性生活频率、避孕方式、吸烟、年龄、职业是其发生的独立危险因素,需加强对育龄期女性HPV感染知识宣教,增强认知,定期体检,早发现、早治疗。     

血浆滤过透析治疗肝衰竭合并脓毒症的疗效

目的 探讨血浆滤过透析（Plasmadiafiltration,PDF）治疗肝衰竭合并脓毒症的临床疗效。方法 回顾性分析2017年1月至2019年1月我院ICU收治的31例肝衰竭合并脓毒症患者临床资料,上述患者行PDF及抗感染等内科综合性治疗,观察治疗前后临床症状及体征的改善;观察治疗前后凝血酶原活动度(PTA)及纤维蛋白原、天冬氨酸转氨酶(AST)、总胆红素(TBIL)、血氨及终末期肝病模型（MELD）评分变化;观察治疗前后降钙素原(PCT)、白细胞介素6(IL 6)、C反应蛋白(CRP)、血常规、乳酸及序贯性器官功能衰竭(SOFA)评分变化;观察治疗过程中的不良反应。结果 PDF治疗后临床有效率达61.29%,不良反应为8.21%;PDF 治疗前后PTA、纤维蛋白原、TBIL 、AST、Na+、K+、PCT、IL 6、CRP、白细胞(WBC)、乳酸、SOFA及MELD评分差异有统计学意义（P<0.05）。结论 PDF结合内科治疗显著改善肝衰竭合并脓毒症患者的凝血功能和肝功能,同时能清除炎症因子从而有效缓解病情。     

Anatomical site differences of sodium lauryl sulfate-induced irritation: randomized controlled trial

Sodium lauryl sulphate (SLS) is a chemical used to induce skin irritation that mimics irritant contact dermatitis (ICD). ICD is a condition where direct contact with certain substances causes rash, redness, blistering, itching, dryness and cracking of the exposed skin. It is a common occupational disease and accounts for 4-7% of all dermatological consultations in U.K. This SLS induced irritation is often used to test the effectiveness of different treatments that could be used to alleviate the ICD symptoms. Irritation is usually induced on the forearms but other locations such as upper back have been used. The extent of the irritation might be different between different anatomical locations. Those differences could affect the results of the treatment testing. That means that the beneficial effects achieved by the treatment on one location may not be achieved on the other. This study, from Croatia, aimed to investigate variations in skin response to irritation and its effects on treatment in an SLS induced ICD. The irritant was applied on the forearms and the upper back of the healthy volunteers. Emollient (moisturising) cream was chosen as a treatment. One forearm and one side of the back were treated with the emollient for nine days while others were left untreated. The skin parameters that indicate the extent of the irritation and the recovery were measured using skin probes. The authors found that the upper back had stronger reaction to the irritant and faster recovery of the skin than the forearms. Also, the tested emollient cream did not improve the skin recovery. In conclusion, the anatomical location is an important factor influencing the results of the studies testing treatment effectiveness. Future studies should always accurately report the testing location. The results of the studies using this irritation model, but on different anatomical locations, are not necessarily directly comparable.     

人胎盘间充质干细胞的超微结构及其吞噬功能

背景：胎盘间充质干细胞组织来源丰富,与骨髓间充质干细胞有着类似的形态、表面标记物、潜在分化能力,是人体理想的间充质干细胞来源之一。目前对胎盘间充质干细胞超微结构和吞噬功能的研究较少,对其在胎盘组织中的生理功能也鲜有探讨。目的：了解胎盘间充质干细胞的超微结构和吞噬功能。方法：分离培养5个正常娩出胎盘来源的胎盘间充质干细胞,经体外培养后在透射电子显微镜下观察细胞的超微结构;在培养上清中添加荧光微球,孵育3 h后用流式细胞仪检测细胞的吞噬能力。结果与结论：胎盘间充质干细胞在透射电镜下表现为细胞核比较大,核仁明显;核膜折叠、内陷显著,常染色质多,核浆比例正常。内质网系统发达,可见大量狭小或扩张的粗面内质网。胞浆内高尔基器、溶酶体常见;细胞表面微绒毛发达,偶可见细胞间连接。5个标本的胎盘间充质干细胞中均有部分细胞能吞噬荧光微球,最多有49.6%,最少有18.4%。上述胎盘间充质干细胞的超微结构特点提示细胞功能活跃,可合成和分泌大量蛋白质,并具有吞噬功能;而吞噬实验进一步验证胎盘间充质干细胞吞噬异物的能力,提示胎盘间充质干细胞在胎盘中可能起着维持微环境稳态、清除异物的功能。中国组织工程研究杂志出版内容重点：干细胞;骨髓干细胞;造血干细胞;脂肪干细胞;肿瘤干细胞;胚胎干细胞;脐带脐血干细胞;干细胞诱导;干细胞分化;组织工程全文链接：
