丝裂素活化蛋白激酶磷酸酶-1对血管平滑肌细胞增殖的影响及其机制

目的 研究丝裂素活化蛋白激酶磷酸酶-1(MKP1)对血管平滑肌细胞增殖的影响及机制。方法 转染MKP1质粒72h后，收集培养的血管平滑肌细胞(VSMC)，利用P^42／P^44磷酸化抗MAPK抗体通过免疫印迹法测定MAPK活性，用流试细胞仪测定细胞周期、细胞周期素和P27蛋白的表达。结果 转染MKP1质粒后，MAPK活性明显下降，VSMC阻滞于G0-G1期，同时抑制了细胞周期素D、E的表达，P27蛋白表达却明显增加。结论 MKP1抑制VSMC增殖可能是通过降低MAPK活性，抑制细胞周期素表达和增加P27蛋白表达途径实现的。

目的探讨腹腔镜经胆囊管探查取石术和腹腔镜胆总管切开取石术的手术效果及术后恢复情况。方法回顾性分析肝胆外科2014年1月至2017年7月胆囊结石合并胆总管结石患者100例的临床资料。其中行腹腔镜胆囊管探查取石(胆囊管组)55例,行腹腔镜胆总管切开取石、T管引流(胆总管组)45例。结果 2组患者手术时间、术中出血、术后首次排气时间、术后止痛药物时间、腹腔引流管留置时间、术后胃管拔除时间、术后并发症、术后住院时间、住院费用相比,差异均有统计学意义(P<0.05);而术后留置尿管时间、术后3 d丙氨酸氨基转移酶、术后3 d天冬氨酸氨基转移酶、术后3 d总胆红素差异无统计学意义(P>0.05)。结论腹腔镜经胆囊管探查取石术的手术效果及术后恢复情况优于腹腔镜胆总管切开取石、T管引流,是一种有效、安全的治疗方法。     

晚期血吸虫病患者肝内T细胞亚群的免疫组织化学检测

采用免疫组织化学技术检测了２２例晚期血吸虫病（下称晚血）患者肝内Ｔ细胞亚群。发现晚血患者肝内Ｔ细胞可集中分布于虫卵肉牙中外层或者菜知分布于非肉芽肿部位的虫卵附近，广泛纤维化的区域无Ｔ细胞浸润。肉芽肿和非肉芽肿部位的Ｔ细胞均以ＣＤ８＾＋Ｔ细胞（抑制性／细胞毒Ｔ细胞）为主。晚血患者肝脏病变以汇管区纤维化主，浸润细胞不多，仅２７．２７％（６／２２）患者肝内存在已被免疫调节了的慢性虫卵肉芽肿。提示晚血患者     

生物反应器中的力学刺激促进组织工程软骨再生

BACKGROUND: Cartilage tissue engineering has been widely used to achieve cartilage regeneration in vitro and repair cartilage defects. Tissue-engineered cartilage mainly consists of chondrocytes, cartilage scaffold and in vitro environment. OBJECTIVE: To mimic the environment of articular cartilage development in vivo, in order to increase the bionic features of tissue-engineered cartilage scaffold and effectiveness of cartilage repair. METHODS: Knee joint chondrocytes were isolated from New Zealand white rabbits, 2 months old, and expanded in vitro. The chondrocytes at passage 2 were seeded onto a scaffold of articular cartilage extracellular matrix in the concentration of 1×106/L to prepare cell-scaffold composites. Cell-scaffold composites were cultivated in an Instron bioreactor with mechanical compression (1 Hz, 3 hours per day, 10% compression) as experimental group for 7, 14, 24, 28 days or cultured statically for 1 day as control group. RESULTS AND CONCLUSION: Morphological observations demonstrated that the thickness, elastic modulus and maximum load of the composite in the experimental group were significantly higher than those in the control group, which were positively related to time (P < 0.05). Histological staining showed the proliferation of chondrocytes, formation of cartilage lacuna and synthesis of proteoglycan in the experimental group through hematoxylin-eosin staining and safranin-O staining, which were increased gradually with mechanical stimulation time. These results were consistent with the findings of proteoglycan kit. Real-time quantitative PCR revealed that mRNA expressions of collagen type I and collagen type II were significantly higher in the experimental group than the control group (P < 0.05). The experimental group showed the highest mRNA expression of collagen type I and collagen type II at 21 and 28 days of mechanical stimulation, respectively (P < 0.05). With the mechanical stimulation of bioreactor, the cell-scaffold composite can produce more extracellular matrix, such as collagen and proteoglycan, strengthen the mechanical properties to be more coincident with the in vivo environment of cartilage development, and increase the bionic features. With the progress of tissue engineering, the clinical bioregeneration of damaged cartilage will be achieved.   中国组织工程研究杂志出版内容重点：组织构建;骨细胞;软骨细胞;细胞培养;成纤维细胞;血管内皮细胞;骨质疏松;组织工程     

安徽省麻疹野毒株的首次分离和鉴定

为了监测安徽省现流行的麻疹野毒株,在1998、1999年的2起麻疹暴发中,用绒猴淋巴母细胞（B95a）分离到4株麻疹野病毒,通过血凝试验、血吸附试验、中和试验对分离到的麻疹病毒进行特性鉴定。该4株病毒无血凝和血球吸附活性,我国人类疫苗免疫后,血清能中和这4株病毒,但中和此野毒株的滴度低于中和疫苗株滴度的2倍。逆转录聚合酶链反应（RT－PCR）和其产物的基因序列分析提示,该4株病毒属于麻疹病毒第八基因组（Hgroup）。继续监测我国各省麻疹流行株的基因和抗原变异,对我国强化麻疹控制及麻疹消除、消灭十分必要
