骨蚀宁胶囊联合唑来膦酸治疗早中期股骨头坏死的临床疗效观察

目的 评估骨蚀宁胶囊联合唑来膦酸治疗早中期股骨头坏死的临床疗效.方法 将股骨头坏死(早中期)患者64例随机分为对照组和观察组,每组32例,其中观察组38髋,对照组35髋.对照组予以唑来膦酸静脉滴注,口服骨化三醇及碳酸钙D3治疗;观察组在对照组治疗的基础上予以中药骨蚀宁胶囊口服.治疗1年后通过门诊随访调查患者治疗后髋关节Harris评分、基于X线片评分的疗效.结果 两组临床疗效比较,差异有统计学意义(P<0.05).与治疗前比较,两组治疗1年后髋关节功能、畸形、活动度和疼痛评分均显著升高(P<0.05);观察组治疗1年后髋关节功能、疼痛、活动度评分均显著高于对照组(P<0.05).结论 骨蚀宁胶囊联合唑来膦酸、骨化三醇及碳酸钙D3能更显著改善股骨头坏死症状,延缓股骨头进一步塌陷.     

Evaluation of photometric stereo and elastomeric sensor imaging for the non-destructive 3D analysis of questioned documents – A pilot study

Photometric Stereo and Elastomeric Sensor Imaging were assessed for measuring the 3-dimensional (3D) morphology of questioned document samples. Photometric stereo is shown to be a powerful non-contact technique for revealing micron level detail of the samples examined. Elastomeric Sensor Imaging is shown to complement photometric stereo by yielding equivalent results. Additionally, this technique allows quantification of the morphological depth information. The techniques were applied to 2 different types of questioned document sample. Firstly, written signatures were examined. Both techniques were able to reveal characteristic features that could be used to infer stroke direction and ink line application sequence. Secondly toner/ink intersections were examined. Both techniques allowed visualisation of 3D features which were used to infer the sequence of application.     

化瘀温经利湿法治疗慢性盆腔炎20例临床观察

目的观察化瘀温经利湿中药对慢性盆腔炎患者的疗效及对外周血CD4^＋CD25^＋CD127^lo调节性T细胞（regulative Tcells，Treg）的影响。方法将40例慢性盆腔炎患者按随机数字表法分为化瘀温经利湿中药治疗组20例和西药对照组20例，两组均以1个月为1个疗程，均治疗1个疗程，观察临床疗效及对症状出现率的影响；采用流式细胞术检测患者治疗前后外周血CD4^＋CD25^＋CD127^loTreg的数量及其在CD4^＋T淋巴细胞中所占的比例；并检测治疗前后血沉（erythrocyte sedimentation rate，ESR）和C反应蛋白（C—reactive peptide，CRP）水平。结果与对照组比较，治疗组总有效率和CD4^＋CD25^＋CD127^loTreg表达水平显著升高，ESR、CRP及症状出现率显著降低（P〈0．05）。结论化瘀温经利湿中药治疗慢性盆腔炎的作用机制，可能与其上调CD4^＋CD25^＋CD127^loTreg表达水平，促进免疫调节，降低炎症反应有关。     

Investigation of the variability in the tool marks produced by modified blank firing pistols on fired 7.65 mm projectiles

Firearms identification has an important place in forensic ballistic investigations since the weapons are widely used in criminal offences. Firearm examiners resolve many case files, through the use of automatic systems or comparison microscopes. Advanced forensic technologies like BALİSTİKA helps to record and analyze non standard ballistic evidence. In today's world, with the ease of access to materials and production technique information, pistols modified from blank firers are frequently encountered as crime tools. In this study, the characteristics of 7.65 mm fired cartridge cases obtained by controlled shots from blank firing modified pistols were examined, and their detection performances were compared by means of the Balistika system. Although distinctive differences are not expected after successive test shootings, balistically important changes were seen after the use of blank firing modified pistols and the 3D imaging system proved to be useful in observing such differences. The analyses showed that the modifications in weapons lead to variation in the ballistic characteristics and reduce the accuracy of the detection performance, which may result in flawed forensic decisions. It was also found that the deviations in ballistic impressions of modified blank firing pistols were greater than that of standard fabricated and hand-made pistols. This unique study contributed to the forensic sciences literature by focusing on the impact of modified weapons on ballistic characteristics.     

Lipidic compounds found in soils surrounding human decomposing bodies and its use in forensic investigations – A narrative review

Following decomposition of a human body, a variety of decomposition products, such as lipids, are released into the surrounding environment, e.g. soils. The long-lasting preservation in soils and their high diagnostic potential have been neglected in forensic research. Furthermore, little is known about the preservation, chemical transformation, or degradation of those human derived lipids in soils. To date, several studies identified various lipids such as long-chain free fatty acids and steroids in soils that contained decomposition fluids. Those lipids are preserved in soils over time and could serve as markers of human decomposition in forensic investigations, e.g. for estimating the post-mortem interval or identifying the burial location of a human body. Therefore, this review focuses on the current literature regarding fatty acid and steroid that have been detected in soils and associated with human body decomposition. After a short introduction about human decomposition processes, this review summarises fatty acid and steroid analysis applied in current case studies and studies related to taphonomic research. This review provides an overview of the available studies that have used fatty acids and steroids as identifiers of human decomposition fluid in soils in a forensic context and discusses the potential for developing this innovative field of research with direct application in a forensic context.
