谷氨酰胺肠外营养对创伤后多器官衰竭患者的营养作用

目的探讨补充谷氨酰胺(Gln)的肠外营养在严重创伤后多器官衰竭(MOF)患者治疗中的作用。方法采用随机对照方法,将60例MOF患者分为Gln组和对照组,每组30例。Gln组给予Gln1.5ml/kg联合常规治疗[热量104～125kJ/(kg·d),其中脂肪供热40%,氮供给量为0.2～0.25g/(kg·d)的完全胃肠外营养(TPN)支持];对照组仅给予常规治疗,连续7d。对照分析营养指标、免疫指标、并发症及临床结果。结果所有患者营养指标(血清白蛋白、前清蛋白、转铁蛋白)和免疫指标(IgG、IgA、IgM)明显减低,处于负氮平衡。第8天时,Gln组营养指标明显高于治疗前及对照组(P<0.05),负氮平衡得到纠正(P<0.05),而对照组仅血清白蛋白、转铁蛋白较治疗前增高(P<0.05),仍处于负氮平衡(P>0.05)。Gln组免疫指标明显高于治疗前及对照组(P<0.01),而对照组仅IgG高于治疗前(P<0.01)。对照组14例(46.7%)出现了血清胆红素、丙氨酸转氨酶和血糖的升高,而Gln组仅4例(13.3%)增高(P<0.05),至14d时对照组病死率为36.7%,而Gln组仅为10%,两者相比差异有显著性(P<0.05)。结论应用Gln的肠外营养能够明显纠正MOF患者的营养代谢障碍,纠正负氮平衡,增强免疫功能,降低并发症及病死率。     

藤茶提取物的抗炎作用研究

目的：采用几种不同类型的炎症动物模型对AGE的抗炎作用进行研究。方法：大鼠角叉菜胶性足肿胀，醋酸诱导的小鼠腹腔毛细血管通透性增高，小鼠羧甲基纤维素囊中的白细胞数目，大鼠巴豆油性气囊肿的形成。结果：连续灌胃给药5天，AGE（5、10g/kg）可以显著抑制角叉菜胶所致的大鼠足肿胀、醋酸所致的小鼠腹腔毛细血管通透性增高、小鼠羧甲基纤维素囊中白细胞的游出数目以及大鼠巴豆油性气囊的形成。结论：藤茶提取物具有显著的抗炎活性。     

我焗花螺献给你

想起吃饭，奶猪有时候高兴．有时候不高兴。 老头儿猪对她说过．挨饿的时候他总惦记自杀，因为他见到那势头，总觉得躲不过去。之所以后来还活着．是因为他想到要是不死，保不准哪天还能吃上碗红烧肉，死了可就板上定钉永远也吃不上了。老头儿猪因为这个崇高的信念咬牙切齿地养大了肉猪他爸肉猪他爸又养大了肉猪。肉猪是奶猪的男朋友，肉猪他爸和老头儿猪把肉猪叫肉猪，肉猪把奶猪叫奶猪，肉猪说：“这样好，听起来就胖乎乎香喷喷的”。     

肝细胞癌合并胆管癌栓患者术中癌栓的处理

目的 探讨肝细胞癌（HCC）合并胆管癌栓患者术中癌栓的处理方式和术后恢复过程。方法 对1995年1月-2002年12月手术治疗的27例HCC合并胆管癌栓情况进行回顾性总结和分析。结果 只有59．3％（16／27）患者行肝切除、胆管取癌栓及胆管引流术。全组术后并发症发生率为55．6％（15／27），术后30d病死率为22．2％（6／27）。结论 HCC合并胆管癌栓的预后差，早期诊断和外科手术治疗是改善此病预后的关键。     

Parkinson''s disease in China. Coordinational Group of Neuroepidemiology, PLA.

An epidemiological study on the incidence and prevalence of Parkinson's disease (PD) was carried out in 29 provinces, cities and autonomous regions in this country in 1986. The survey was conducted in 117 areas, and 566 patients with PD were found among 3,869,162 persons examined, giving a point prevalence for men and women of 16.9/10(5) and 12.4/10(5), with the highest prevalence after the fifth decade of age. The disease was most prevalent in the southern part of China, especially in Hunan and Guangxi provinces. The incidence was 1.5/10(5)/yr in 1986. Both the prevalence and incidence of PD in China are lower than those in the white race and Japanese.

     

自助餐：精致的“大锅饭”

请客做东的朋友，点菜的时刻也许是他们最煞费心机的时候：一边是担心点的菜没有特色、不好吃而令客人扫兴，一边又怕菜价太高，“钱袋子”不堪负荷。如果不想遭遇这种尴尬，吃自助餐可能是最好的选择。[编者按]     

Characteristics of the Nonselective Cation Current （NSCCs） in Rabbit Left Ventricular Epicardial, Midmyocardial and Endocardial Myocytes

Objectives Recent studies have described regional differences in the electrophysiology and pharmacology of ventricular myocardium in canine, feline, rat, guinea pig, and human hearts. This has been shown to be due to a smaller IKs and a lager sodium-calcium exchange current (INa-Ca) and late INa in M region (deep subepicardial to midmyocardial). Studies from our laboratory have found a new repolarization current-nonselective cation current (NSCCs) existing in rabbit right ventricular myocytes. Methods We examined the characteristics of NSCCs in epicardial, M region, and endocardial cells isolated from the rabbit left ventricle with standard microelectrode and whole-cell patch-clamp techniques. The permeability to Na , K , Li , Cs but not to Cl- indicating that it was a nonselective cation current. Gd3 (0.1 mmol/l) and La3 (0.1 mmol/l) can block the current markedly. Results Further characterization of NSCCs was significantly smaller in M cells than in epicardial and endocardial cells. NSCCs current density was significantly smaller in M cells than in epicardial and endocardial cells. With repolarization to -80 mV, INs current density was (-0.44±0.05) PA/PF in endocardial cells, (-0.12±0.05) PA/PF in M cells and (-0.28±0.07) PA/PF in epicardial cells; and with repolarization to 30 mV, INs current density was (1.09±0.29) PA/PF in endocardial cells, (0.38±0.09) PA/PF in M cells and (0.91±0.32) PA/PF in epicardial cells. Conclusions Transmural dispersion of repolarization was due to the heterogeneity of NSCCs in rabbit left ventricle epicardial, endocardial myocytes and M cells. These findings may advance our understanding of the ionic basis for our understanding of factors contributing to the development of cardiac arrhythmias.     

Significance of changes in serum superoxide dismutase level in hypertensive syndrome of pregnancy.

The concentration of human serum superoxide dismutase-1 (hSOD-1) containing copper and zinc ions were measured by radioimmunoassay healthy nonpregnant women, 15 normal pregnant women, 15 patients with mild to moderate hypertension (MMHSP) and 15 with severe hypertensive syndrome of pregnancy (SHSP). The mean serum hSOD-1 concentration in nonpregnant women was 148.84 +/- 60.53 (x +/- s) micrograms/L; while in the other 3 groups it was 394.19 +/- 122.21 micrograms/L, 377.12 +/- 173.45 micrograms/L and 581.15 +/- 118.50 micrograms/L. The results suggest that harmful free radicals increase gradually and a strong body defence system against oxidation damage of tissue cells is produced in the course of normal pregnancy and MMHSP. With cardionatrin treatment serum hSOD-1 concentrations of patients ameliorated returned to the level of normal pregnancy. The results indicate that there is a positive correlation between cardionatrin and hSOD-1 levels (r = 0.569, P less than 0.05), and a physiological regulation of the defence system exists, which may be related to the white blood cells. Hence, hSOD-1 probably plays a significant role in defence during normal pregnancy and hypertensive syndrome of pregnancy (HSP).
