Objective To investigate the the effect and interaction of morphine dependence model and naloxone doses on withdrawal intensity. Methods To observe the withdrawal signs and weight loss in two kinds of morphine dependent rats after the precipitating by naloxone of different doses an devaluate the withdrawal intensity.Results Morphine dependence were successfully induced in two ways.There was no significant difference of withdrawal intensity in five-day model(total morphine dose 380mg.kg－1) after precipitating by naloxone of 2mg.kg－1 and 4mg.kg－1（P＞0.05）. Withdrawal intensity of twelve-day model(total morphine dose 1365mg.kg－1)increased significantly with the increase of naloxone dose（P＜0.01）,but it was more intensive significantly than five-day model only after 4mg.kg－1 dose of naloxone. Conclusion Appropriate method should be used to induce morphine dependence and these experimental factors should be combined in assessment of withdrawal intensity.

The liver is an important organ of the body, which has many functions, such as metabolism and detoxification. Due to the rapid change of lifestyle and the improvement of public health, the incidence rate of non-communicable diseases has increased significantly, which fundamentally changed the disease characteristics in most parts of the world. At present, the global prevalence of non-alcoholic fatty liver disease (NAFLD) is about 25%. Moreover, about 59.10% of NAFLD patients progress to non-alcoholic steatohepatitis (NASH) within 5 years, and about 41% of NASH patients progress to fibrosis. NAFLD has become one of the most important liver diseases in the world and may become the main cause of end-stage liver disease in the next few decades. In addition, NAFLD and related cirrhosis will bring huge economic burden to patients, health care system and society. Since there are currently no medications available that have been approved by Food and Drug Administration (FDA), NAFLD is still treated mainly through lifestyle changes such as exercise and diet. Oxidative stress and inflammation are the most important pathological processes in the occurrence and development of liver diseases. Nuclear factor erythroid-2-related factor 2 (Nrf2) is a key regulator of the body's antioxidant stress system, with anti-inflammatory, antioxidant and other functions. Many studies have shown that Nrf2 pathway significantly affects the progression of liver diseases. In this review, we aimed to summarize the regulatory role of the Kelch-like ECH-associating protein 1 (Keap1)-Nrf2-antioxidant response element (ARE) signaling pathway in the pathogenesis of NAFLD, and to reveal the potential of Nrf2 as a therapeutic target for NAFLD.

To investigate constituent ratio and drug resistant status of pathogenic bacterium in SCI patients with urinary infection.The germ cultures of midstream urine samples and identifications to 456 stains pathogenic bacterium were conducted,susceptibility to antibiotics were tested.The results showed that G- baccili occupied absolute predominance among pathogenic bacterium.It is very important to select antibiotics rational for urinary infections of SCI patients according to the results of susceptibility tests.

Objective To study the methods and outcome of 71 patients with Parkinson's disease treated with microelectrode-guided stereotactic pallidotomy and thalamotomy. Method Pallidal and thalamal target sites are chosen by supervision of microelectrode recording technique in 71 patients with Parkinson's disease. The UPDRS motor score was used to evaluate the outcomes 12 weeks before and after operation Result After 12 months follow-up, tremor disappeared completely or nearly completely in 12 patients who underwent unilateral and l bilateral ventrolateral thalamotomy. Dramatic improvement of tremor, rigidity, bradykinesia were observed in 57 patients underwent posteroventral pallidotomy,including 6 underwent bilateral posteroventral pallidotomy. Intracerebral hemorrhage was observed in l patient. Conclusion Microelectrode-guided stereotactic pallidotomy and thalamotomy are effective in treatmenting Parkinson's disease, but with serious complications

Objective To evaluate the clinical effect of the enteral nutrient(Pediasure) on making improvements in nutritional status of children with anorexia.Methods Thirty children were treated with pediasure for 2 months, twice a day, and height(Ht),weight(Wt),AG,TSF,SSF,ASF,RBC,Hb were measured before and after treatment and their appetites,alimentary canal reactions were recorded.Results Compared with the effects after 2 months, the average Ht,Wt,AG,SF all increased, and there was significant difference between pretreatment and after treatment(P0.05). All of the 30 children had no adverse reactions during treatment.Twenty-two children (73.33%) had better appetites and increased the amount of eating after treatment.Conclusion The study suggests that pediasure may be safely used in the treatment of children′s anorexia and effectively improve patients′ nutrition without adverse reactions.
