鳖鳃腺炎与腐皮病并发症的组织病理学研究

对鳃腺炎与腐皮病并发症的鳖的肝、脾、肾、肺、肠和精巢等6种器官进行病理组织学切片,并与健康鳖的相应器官组织进行比较。结果显示：病鳖的器官组织出血,组织细胞出现肿胀、坏死、崩解,最终造成全生组织损伤;血管腕扩大,血管壁严重受损,内皮细胞坏死脱落;血管内及血液中的大量红细胞变形、破裂、溶解。此外,还对病鳖的4种组织匀浆液初步进行了抑菌实验。     

核受体Rev-erbs的能量稳态调控作用及其运动科学研究展望

 核受体Rev-erbs是能量稳态调控的核心转录调节因子,其表达受饮食、药物、运动等因素的影响;Rev-erbs参与糖脂代谢、胰岛素分泌、血糖稳态调节等多个生物学过程,是肥胖症、糖尿病等慢性代谢性疾病治疗的重要药物靶标,通过调节糖脂代谢通路中的靶分子,调控组织的能量稳态。运动干预刺激肝脏、骨骼肌等组织中Rev-erbs表达,调控糖脂代谢基因,维持细胞能量稳态,可能是慢性病运动干预的重要适应机制。简述了Rev-erbs的结构特点、表达调控因素与作用机制,分析了运动干预对Rev-erbs表达的影响与代谢调控机制,以及Rev-erbs在运动科学领域的国际前沿和发展趋势。

Beyond Chemoselectivity: Catalytic Site‐Selective Aldolization of Diketones and Exploitation for Enantioselective Alzheimer's Drug Candidate Synthesis

Site selectivity, differentiating instances of the same functional group type on one substrate, represents a forward‐looking theme within chemistry: reduced dependence on protection/deprotection protocols for increased overall yield and step‐efficiency. Despite these potential benefits and the expanded tactical advantages afforded to synthetic design, site selectivity remains elusive and especially so for ketone‐based substrates. Herein, site‐selective intermolecular mono‐aldolization has been demonstrated for an array of prochiral 4‐keto‐substituted cyclohexanones with concomitant regio‐, diastereo‐, and enantiocontrol. Importantly, the aldol products allow rapid access to molecularly complex ketolactones or keto‐1,3‐diols, respectively containing three and four stereogenic centers. The reaction conditions are of immediate practical value and general enough to be applicable to other reaction types. These findings are applied in the first enantioselective, formal, synthesis of a leading Alzheimer's research drug, a γ‐secretase modulator (GSM), in the highest known yield.     

ICAM-1,TNF-α在原发性肝癌中表达的相关性分析

采用酶联免疫吸附试验检测原发性肝癌及正常体检人群各56例血清中ICAM-1和TNF-α的表达,免疫组化方法检测56例原发性肝癌组织标本的ICAM-1和TNF-α蛋白的表达.结果显示ICAM-1和TNF-α在原发性肝癌血清中存在异常表达(p<0.05),不同组织分型原发性肝癌患者血清中ICAM-1水平、TNF-α水平无差异(p>0.05),原发性肝癌组织中ICAM-1和TNF-α蛋白的表达呈正相关(r=0.216,p=0.000).ICAM-1和TNF-α的表达可能是原发性肝癌病理进程中的普遍现象,检测原发性肝癌患者血清ICAM-1和TNF-α含量,可为患者个性化治疗提供实验室依据,改善患者的预后.     

虎杖对大鼠酒精性脂肪肝的干预作用及其机制研究

目的探讨中药虎杖对酒精性脂肪肝模型大鼠的防治作用。方法以白酒灌胃的方法建立酒精性脂肪肝大鼠模型。大鼠随机分为空白对照组、模型组、凯西莱(阳性对照)组、虎杖大、中、小剂量组。以肝指数,内脏脂肪指数,血清NO、ALT、AST、CHOL、TG、LDL、HDL,肝组织匀浆SOD、MDA和肝组织脂肪变性程度等为主要观察指标。结果与模型组比较,虎杖大剂量组肝小叶中仅有少量细胞脂肪变性,肝细胞内脂滴颗粒较小,肝指数、内脏脂肪指数、AST、ALT、MAD和NO降低、SOD升高;虎杖中剂量组除AST外也降低;虎杖小剂量组肝指数降低;虎杖大、中、小剂量组TG、CHOL、HDL、LDL均显著降低(P0.01,P0.05)。结论虎杖对酒精性脂肪肝有明显的防治作用。     

Feasibility study of high intensity focused ultrasound (HIFU) for the treatment of hydatid cysts of the liver

This study evaluates the feasibility of using high intensity focused ultrasound (HIFU) for the treatment of hydatid cysts of the liver. HIFU ablation was carried out in 62 patients with echinococcosis of the liver. The mean age of patients was 40.76 ± 14.84 (range: 17–72 years). The effectiveness of the treatment was monitored in real-time by changes in the gray-scale, and by morphological studies, computed tomography, magnetic resonance imaging, and ultrasound.Criteria for evaluating the effectiveness of treatment in real time were outlines. Cytomorphological picture of destructive changes of parasitic elements was presented as well. Loss of embryonic elements of the parasite was observed at the subcellular level after HIFU-ablation and underlines the effectiveness of HIFU.
