| 1 | 我国胆石病十年来的变迁显示文摘作者报道了由全国胆道外科学组组织的来自7个省市、33所医院3911例胆结石手术病例的第二次全国临床调查资料并与十年前首次调查的结果(中华外科杂志1987,25:321~329)比较。调查证实:胆石病仍是我国普外临床的多发病,约占同时期住院患者的11.5%;多见于50岁以上的女性;女:男约2.57:1。约80%的单一部位结石分布于胆囊,以胆固醇类结石为主;而以胆色素类为主的胆管结石仅占10%。与十年前相比,胆囊:胆管结石从1.5:1上升至7.36:1;胆固醇:胆色素结石从1.4:1升至3.4:1。调查还发现:上述关于结石类型及结石部位上的变化与近十年来胆道蛔虫及胆道感染率的显著下降及饮食结构的变化有关。 | Zhu Xueguang Zhang Shengduo HuangZhiqiang et al.

| 2 | Protective Effect and Mechanism of Polysaccharides from Cordyceps cicadae on Acute Liver Injury Induced by D-GlaN in Mice显示文摘[Objectives]To observe the protective effect of Cordyceps cicadae polysaccharides on acute liver injury induced by D-galactosamine( D-GlaN) in mice,and to explore its mechanism. [Methods] Seventy-five male Kunming mice were randomly and evenly divided into 5 groups according to the digital table method: normal group( CK)( injected intraperitoneally with saline solution),model group( injected intraperitoneally with D-GlaN),low-dose C. cicadae polysaccharides group( administered with 0. 5 g/kg of C. cicadae polysaccharides solution by gavage),middle-dose C. cicadae polysaccharides group( administered with 1. 0 g/kg of C. cicadae polysaccharides solution by gavage) and high-dose C. cicadae polysaccharides group( administered with 2. 0 g/kg of C. cicadae polysaccharides solution by gavage). After 12 d of administration,the liver histopathological score,liver homogenate indexes( superoxide dismutase,SOD; malondialdehyde,MDA; glutathione peroxidase,GSH-Px; nitric oxide,NO) and serum markers( aspartate transaminase,AST; alanine transaminase,ALT; alkaline phosphatase,ALP; cholinesterase,CHE) of mice in each group were detected. The expression levels of nuclear factor-κB( NF-κB) and tumor necrosis factor-α( TNF-α) in liver tissues were detected by immunohistochemistry. [Results]The liver histopathological score and the MDA,NO,AST,ALT,ALP,NF-κB and TNF-α levels were significantly higher( P < 0. 05) and the SOD,GSH-Px and CHE levels were significantly lower( P <0. 05) in the model group compared with the normal group. Compared with those in the model group,the liver tissue histopathological scores in the low-,middle-and high-dose C. cicadae polysaccharides groups were all significantly reduced( P < 0. 05). With the increase of treatment dose,the liver tissue histopathological scores showed a significant decrease( P < 0. 05). Compared with the model group,the levels of MDA,NO,AST,ALT,ALP,NF-κB and TNF-α were significantly lower( P < 0. 05),and the levels of SOD,GSH-Px and CHE were significantly higher( P < 0. 05) in the low-,middle-and high-dose C. cicadae polysaccharides groups. With the increase of treatment dose,the levels of MDA,NO,AST,ALT,ALP,NF-κB and TNF-α declined significantly( P < 0. 05),while the levels of SOD,GSH-Px and CHE rose significantly( P < 0. 05). [Conclusions] C. cicadae polysaccharides have a significant protective effect on D-GlaN-induced acute liver injury in mice in a dose-dependent manner,and the mechanism may be related to the inhibition of NF-κB inflammatory signaling pathway. | Ping WEN Shengduo CHEN Bing ZHENG Haili LIANG Ting WANG Liying BAI Junxiu TAO Xian ZHANG Jiarui WANG | 2018 | Medicinal Plant2018，9，4： | 0 |
