膝骨关节病的关节镜诊断治疗

目的 通过对79例84膝骨关节病的关节镜诊断治疗回顾性总结,探讨高效率、创伤小、疗效佳的方法。方法 采用关节镜微创技术,结合术前检查对膝骨关节病分为：软骨破坏型,滑膜类型,游离体型及半月板型,依此施行有针对性,局限化手术治疗。结果 69膝得到6mo-3a的随访,按膝关节综合评分表评分,优20％,良59％,可和差21％。结论 该方法具有创伤小、康复快、并发症少等优点,在病损严重的病例,全膝置换或截骨术是进一步提高总体疗效的适宜选择。     

家兔胸部火器伤后各组织中TNF-α表达意义

目的 用免疫组织化学方法检测家兔胸部火器伤后各组织中TNF-α的表达,探讨其伤后表达变化规律。方法 64只家兔随机均分8组,除正常对照组外均用5.56mm小口径步枪距离6m射击兔右下胸第八肋间锁骨中线外1cm处造成前后胸贯通伤,经指袢排气及消毒缝闭胸壁伤口等简单救治,致伤7组家兔分为伤后0.5,1,6,24和72h,7d,30d取材组,每只均取伤肺距伤道2mm处、1cm处,邻叶中部、与伤道对应的对侧肺处、左室壁、肝肾、脑、垂体、肾上腺取组织标本,行免疫组织化学染色检测组织TNF－α表达。结果 伤后0.5h各组织中TNF－α表达即升高（P＜0.01）,6h已达高峰,持续数天,7d后降低,30d后与伤前无明显差别。不同时间组同一组织TNF－α表达定位基本相同,而表达强度有所不同。结论 家兔胸部火器伤后各组织中TNF－α表达明显升高并与损伤时间密切相关,同一组织TNF－α表达定位基本相同,TNF-α在各组织中表达强度一定程度上反映了动物伤情。

Transcriptome analysis of Armillaria gallica 012 m in response to auxin

Gastrodia elata is an achlorophyllous and fully mycoheterotrophic orchid which obtains carbon and other nutrients from Armillaria species in its life cycle. Many researchers suggested that plant hormones, as signing molecules, play a central role in the plant–fungi interaction. In the process of Armillaria gallica 012 m cultivation, both exogenous indole-3-acetic acid (IAA) and indole-3-butyric acid (IBA) distinctly stimulated the growth of mycelia in solid media. The differential expression genes (DEGs) of A. gallica 012 m with IAA versus blank control (BK) and IBA versus BK were investigated. The results showed that more than 80% of DEGs of the IAA group were coincident with the DEGs of the IBA group, and more than half of upregulated DEGs and most of the downregulated DEGs of the IAA group coincided with those DEGs of the IBA group. Above research implied that A. gallica 012 m could perceive IAA and IBA, and possess similar responses and signaling pathways to IAA and IBA. The overlapping differential genes of the IAA group and IBA group were analyzed by GO term, and the results showed that several DEGs identified were related to biological processes including positive regulation of the biological process and biological process. The downregulated NmrA-like and FKBP_C genes might be benefit to the growth of mycelia. Those results can explain that exiguous IAA and IBA improved the growth of A. gallica to some extent. We speculate that IAA and IBA are signaling molecules, and regulate the expression of growth-related genes of A. gallica 012 m by the same signaling pathway.     

Poly (triethylenglycol monomethacrylate) and poly(glycerol monomethacrylate) cross-linked gel as potential viscoelastics for intraoperative use

Background: The highly swelling poly(glycerol monomethacrylate) gel (polyGLYMA) and hydrophilic polymer poly(triethylenglycol monomethacrylate (polyTEGMA) were tested as potential viscoelastics for intraopertive use in anterior segment surgery. Methods: PolyGLYMA was implanted into the anterior chamber in 5 rabbits, and 40% polyTEGMA in 16 rabbits. The eyes were enucleated 1 week to 3 months after the operation. The corneal endothelium was examined with specular microscopy, and then the whole eye histopathologically. Results: In all eyes of the polyGLYMA group, the clinical findings were characterized by a marked ciliary injection and severe secondary glaucoma, and the histologic ones by a marked inflammatory infiltration and thickening of Descemet's membrane in the anterior chamber angle. Specular microscopy revealed a decrease in the endothelial cell density and polymorphism of the endothelial cells. In the polyTEGMA group, the anterior segment and the fundus were physiologic all the time, and specular microscopy and histologic findings showed no degenerative and/or inflammatory changes. Conclusions: PolyGLYMA proved unsuitable for intracameral application in rabbits. The new polymer polyTEGMA is characterized by high biologic tolerance after its implantation into the anterior chamber of rabbits. PolyTEGMA 40% might be considered as a potential viscoelastic material in humans.     

肾性骨病的骨膜下骨吸收

笔者采用手骨直接Ｘ线放大摄影和双手Ｘ线平片来研究慢性肾衰血透病人５１例。特征性的指骨骨膜下吸收放大摄影发现２５例占４９％;平片为１１例占２１．６％,结果表明,放大摄影的阳性率明显高于平片（Ｐ＜０．００５）,骨膜下吸收的二,三指中间指骨桡侧及指骨末端是肾性骨病的“靶区”,认为二者无显著差异（Ｐ＞０．５０）。骨膜下吸收还与血透时间,血磷,血钙和碱性磷酸酶水平相关。
