参附注射液对实验性急性坏死性胰腺炎肠道细菌移位的影响

目的：研究参附注射液对实验性急性坏死性胰腺炎（ANP）时肠道细菌移位的影响。方法：ANP大鼠制模方法采用胰腺被膜下注射牛磺胆酸钠。假手术组、对照组经皮下注射生理盐水，实验组同法给予等量参附注射液。取标本（下腔静脉血、腹水、肠系膜淋巴结及大肠内容物）进行细菌培养，计数菌落数及鉴定细菌种类。结果：标本中生长的细菌与大肠内容物培养细菌种类相同，实验组标本的菌落数少于对照组（P〈0.01）。结论：实验性ANP大鼠合并感染的细菌来源于肠道，参附注射液可以减少肠道细菌移位。     

臭氧水对SARS病毒的灭活效果观察

为了观察电解法产生的臭氧水对SARS病毒的灭活效果,采用悬液灭活试验法进行了试验。结果,以臭氧含量为27.73mg/L,作用4min可完全灭活SARS病毒;以臭氧含量为17.82mg/L,作用4min和4.86mg/L作用10min,均可使SARS病毒的灭活率达100％。结论,电解法产生的臭氧水含臭氧量达到4.86mg/L以上,对悬液内SARS病毒具有很强的灭活效果。

表皮生长因子对全胃肠外营养大部小肠切除大鼠肠适应的实验研究

目的：观察应用表皮生长因子(EGF)对全胃肠外营养(TPN)大部小肠切除大鼠残存小肠黏膜的代偿作用。方法：30只大鼠切除80％小肠后分为对照组、常规TPN组、TPN EGF组，观测体重、小肠黏膜形态学改变，流式细胞仪分析肠黏膜细胞增殖活性。结果：术后3组大鼠体重逐渐降低，1周后渐增加。3组间差异无显著性。TPN组小肠肠壁各层均变薄，黏膜萎缩。TPN EGF组肠黏膜厚度、绒毛高度、隐窝深度较TPN组均增加，S期细胞比率系数、增殖指数TPN EGF组较TPN组高，而TPN捐与对照绸差异无昂著件。结论：TPN联合EGF可晟著地增讲肠黏膜的适应性代偿。     

全肠外营养对老年晚期消化系统恶性肿瘤病人生存期的影响

目的:评估全肠外营养(TPN)对老年晚期消化系统恶性肿瘤病人生存期的影响。方法:回顾性分析121例老年晚期消化系统恶性肿瘤病人TPN治疗后的生存期。结果:TPN治疗后,患者生存期不同程度延长,为9～126天,平均68.1天,多数在两月左右。结论:TPN可延长老年晚期消化系统恶性肿瘤病人的生存期。     

Direct solution to an optimal control problem of econometric systems

A direct solution is proposed to an optimal control problem of linear econometric systems with a quadratic welfare loss function when there are linear equality constraints on the control variables. The direct solution proposed here eliminates the problem of non-uniqueness of the optimal solution, which is present when this optimal control problem is solved using the recursive algorithm proposed by Chow,¹ Pindyck² and Tan.³ If a unique solution to the optimal control problem exists, then the direct solution and the recursive solution coincide.

谷氨酰胺和生长激素对门静脉高压症患者术后营养、免疫和炎症反应的影响

Objective This study was conducted to evaluate the effects of postoperative glutamine and growth hormone on the nutritional status,immune function,and inflammatory responses of patients undergo-ing portal hypertension surgery.Methods This study was designed as a prospective,randomized and con-trolled clinical trial.Forty-two patients undergoing portal hypertension surgery were randomly divided into 2 groups:experimental group (receiving an immune enhancing parenteral nutrition by adding glutamine and re-combinant human growth hormone,n = 22),and control group (receiving an isocaloric and isonitrogenons standard parenteral nutrition,n = 20).Parenteral nutrition providing 125 kJ · kg-1·d-1 was initiated 3 days after surgery in both groups and last for 7 days.Blood samples were obtained on day 0th,3rd,and 10th.Host nutritional status was evaluated by measuring levels of prealbumin and transferrin,immunity was evalu-ated by measuring levels of CD4,CD8,CD4/CD8,IgG,IgM and IgA,and the inflanunatory responses was determined by assessing IL-2,TNF-α and C-reactive protein (CRP) levels.Results Ten days after opera-tion,among patients receiving an immune enhancing parenteral nutrition,the serum prealbumin was (193.84±39.78)mg/L,transferrin was (2.07±0.51)mg/L,CD4 was (33.7±5.5)%,CD4/CD8 was (1.17±0.32),IgG was (13.94±1.09)g/L and IL-2 was (368.12±59.25) pg/mL.They were signifi-cantly higher than those of the control group (P < 0.05).The TNF-α concentrations was (321.12±81.42)pg/mL and CRP was (32.2±15.2)mg/mL which were significantly lower than those of the control group (P < 0.05).Conclusion Postoperative administration of immune enhancing parentearl nutrition in patients undergoing portal hypertension surgery can improve nutritional status and immune function,and modulate inflammatory response is also better than standard one.
