还原型谷胱甘肽联合甘草酸二铵对腹部开放伤后海水浸泡犬肝功能损伤的治疗作用

Objective To investigate effect of reduced glutathione and diammonium glycyrrhizinate on the treatment of hepatic damage in experimental dogs following open abdominal injuries coupled with seawater immersion. Methods Twenty-four dogs with open abdominal injuries were randomly divided into 3 groups: the control group (given with simple observation after 1.5 h seawater immersion); the routine treatment group (given routine care and fluid transfusion after 1.5 h seawater immersion) ; the hepatic treatment group (given routine are, fluid transfusion and hepatic treatment as well, after 1.5 h seawater immersion). Each group consisted of 8 dogs. Blood samples were taken at different time points to measure total bilirubin (TB), alanine aminotransferase (ALT), aspartate aminotransferase (AST), lactate dehydrogenase (LDH), prothromin time (PT), endotoxin, tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6), and pathological examination was also made at the same time. Results For the control group, contents of TB, ALT, AST and LDH increased significantly and survival time was less than 24 hours. Contents of TB, ALT, AST and LDH of the routine treatment group also increased significantly, but survival time of all the experimental animals was mere than 24 hours. Reduced glutathione and diammonium glycyrrhizinate could reduce the extent of lesion quite significantly 12～24 hours following open abdominal injuries. Conclusions Reduced glutathione and diammonium glycyrrhizinate seemed to have good effects on the treatment and prevention against hepatic damage induced by trauma coupled with seawater immersion. It could be used as a primary means for the treatment of such kind of hepatic damage.     

肝硬化病人的心理护理

肝硬化病情迁延不愈,而且无特效治疗方法,治疗费用昂贵,病人因此会出现很多心理问题:焦虑、恐惧,严重情绪不安,被歧视的心理占多数。1年来,我们对50例肝硬化病人进行了心理护理,取得了较好的效果.现报告如下:1 临床资料 50例肝硬化病人中,男37例,女13例,年龄28—72岁.文化程度:初中及以下占28例,高中以上占22例,职业:工人和农民占33例,教师5例,干     

第一、二鳃弓综合征颜面不对称的整形外科矫治

目的探讨第一、二鳃弓综合征面部不对称畸形的整形外科矫治方法。方法根据第一、二鳃弓综合征患者临床及X线所示面部双侧不对称情况,采用健侧下颌骨外板去除、颧骨截骨降低;患侧下颌体、颧骨应用健侧下颌骨外板贴附植骨或高密度多孔聚乙烯(Medpor)假体置入等术式,配合颏部水平截骨颏成形术,以缩小面部双侧宽度的差异,矫治颜面不对称畸形。结果共矫治23例,经6个月至3年的术后随访观察,双侧面部宽度差异明显缩小,正面观面部不对称明显改善。结论第一、二鳃弓综合征面部骨骼发育畸形是三维方向的,双侧面骨宽度的差异,是造成正面观面部不对称的重要因素,根据受术者的具体情况,采用以上术式的组合,扩充患侧或同时缩窄健侧骨骼,进行面部骨性支架重建,可以取得良好的矫治效果。

重组腺病毒介导SOX-9基因对颈椎关节突软骨细胞凋亡的影响

目的 探讨重组腺病毒介导的人SOX-9(AdSOX-9)对人的颈椎关节突关节软骨细胞凋亡细胞数目及Caspase-3基因表达的作用及相关意义,更好理解颈椎软骨退变的发生机制.方法 应用AdSOX-9按照不同浓度及作用时间处理体外培养软骨细胞,应用TdT介导dUTP-生物缺口末端标记方法(TUNEL)及免疫染色方法观察凋亡细胞数量及Caspase-3基因表达变化情况.结果 25MOI、50MOI剂量作用组TUNEL阳性细胞较空白对照组均明显增加;AdSOX-9转染软骨细胞预处理后,空白对照组、25MOI作用组、50MOI三种处理组Caspase-3表达均明显增加,各时点较空白对照组比较,存在显著性差异(P＜0.05).结论 SOX-9基因对软骨凋亡细胞数目、Caspase-3凋亡基因的影响,存在时间-剂量依赖关系,为软骨细胞退变发病机制研究提出新的思考.     

高、寒、旱区坦克、装甲兵腰腿痛病的调查分析

目的 对高、寒、旱区坦克、装甲兵的腰腿痛的状况进行调查并对相关因素分析.方法 本次研究采用问卷调查及实训情况现场调查方式,对1367名在装甲兵腰腿痛状况进行调查.本组调查对象为30岁以下现役男性官兵.结果 ①高、寒、旱区装甲兵平均腰腿痛患病率为41.3%,装甲兵组腰腿痛与非装甲兵组腰腿痛检出率差异有显著性,P＜0.01.②高、寒、旱区装甲兵有患病年龄轻,军龄短、专业影响程度重、环境影响程度明显的显著特点,专业任职时间长短与腰腿痛的比例成正比关系,且程度有渐进性加重趋势.③高、寒、旱区的恶劣自然环境及装甲内不稳定的内环境因素引发装甲兵肌肉疲劳是发生腰腿痛的主要原因.

二氢青蒿素对胰腺癌生长的抑制作用

Objective To investigate the anti-tumor activity of dihydroartemisinin in pancreatic cancer in vitro and in vivo. Methods For cultured cells,cell growth was determined by the MTT assay and apoptosis was evaluated by flow cytometry analysis stained with Annexin V-FITG/PI. The protein expression in BxPC-3 cells was analyzed by Western blot assay. BxPC-3 cells were injected subcutaneously into nude mice to establish pancreatic xenograft tumors and the tumor volume was monitored after exposure to dihydroartemisinin. Ki-67 staining and TUNEL assay were used to assess tumor cell proliferation and apoptosis in tumor tissue. Results After treatment by dihydroartemisinin in vitro, the proliferative inhibition rates of pancreatic cancer cells BxPC-3 and AsPC-1 reached up to (76.2 ± 3.5) % and (79.5 ± 2.9) %, and the apoptosis rates were up to (55.5 ± 3.2)% and (40.0 ± 3.5)%, the differences were significantly (P ＜ 0.01) compared with control [(2.0 ± 1.3) % and (0.9 ± 0.4) %]. Dihydroartemisinin inhibited the growth of pancreatic xenograft tumors in nude mice. The proliferation index and apoptusis index were (49.1 ± 3.9)% and (50.2 ± 4.4)% respectively in dihydroarternisinin 50 mg/kg treatment group, compared to those of (72.1 ± 3.3) % and (9.4 ± 2.9) % in control, the differences were significantly (P ＜0.01). Western blot assay indicated that dihydroartemisinin up-regulates expression of proliferation-associated protein p21WAF1 and down-regulates expression of PCNA, increases expression of apoptosis-associated protein Bax and decreases expression of Bcl-2 and activates caspase-9 in BxPC-3 cells. Conclusions Dihydroartemisinin exerts anti-tumor activity in pancreatic cancer both in vitro and in vivo by proliferation inhibition and apoptusis induction. Dihydroartemisinin can be used as a potential anti-tumor drug in pancreatic cancer.
