Objective To observe the clinical efficacy of three types of drainage in the treatment of malignant obstructive jaundice.Methods 84 patients with malignant obstructive jaundice were selected,40 cases were treated with bridge drainage,24 cases were undergone percutaneous transhepatic cholangial drainage(PTCD) and 20 cases were treated with Roux-En-Y anastomosis.The changes of total bilirubin and direct bilirubin were detected 1,3,7 and 14 days after operation.Results The total bilirubin and direct bilirubin after 1,3,7 and 14 days had significantly decreased compared with pre-treatment(P ＜0.05),the decline rates in bridge drainage group were faster than the other two groups (P ＜ 0.05).Conclusion The three types of drainage for treating malignant obstructive jaundice have exact effect,and the bridge drainage can reduce the bilirubin to lower levels more quickly than the other two methods.

Objective:To design a software to read and display CT and RT structure and draw a new contour without treatment planning system (TPS).Methods: In order to display the contour information drawn by doctors, the first step was to match CT images and RT structure then the same screen rendering of CT and RT structures could be applied. In order to add contour in RT structure obtaining the coordinates interactively, connecting coordinate points were the essential steps. Then a unique identity was given in the area of that contour to ensure its unique results. Results: The software successfully read and displayed CT and RT structures and drew a new contour without TPS.Conclusion: In this study, the software establishes a basis to improve the precision of the radiotherapy dose.

An investigation was made on the rehabilitation treatment for the injuries wounded in Wenchuan Earthquake offered in 30 hospitals of 8 provinces, including Beijing, Shanghai, Jiangsu, Shandong, Hubei, Guangdong, Cbongqing, and Sichuan. On the basis of data from this investigation, the paper made analysis and summary of the challenges and problems encountered in the said rehabilitation treatment, and raises such recommendations as relessing rehabilitation assessment principles and policies for the injuries to return to their home towns in Siehuan, clarifying the responsibilities of individual government authorities in the later-stage rehabilitation treatment of the injuries, and enhanced synergy among respective disciplines and authorities of both clinical practice and rehabilitation treatment. The goal of these recommendations is further development of the rehabilitation medicine discipline in China.

Objective To determine the risk factors for postoperative acute kidney injury (AKI) in the patients undergoing cardiac transplantation.Methods Forty patients with end-stage heart failure (both sexes) , aged 13-66 yr, weighing 45-84 kg, of ASA physical status Ⅳ or Ⅴ (NYHA Ⅲ or Ⅳ), undergoing heart transplantation, with normal kidney function before operation, were selected.According to whether or not AKI occurred within 7 days after operation, the patients were divided into either AKI group or non-AKI group.Factors including age, gender, body weight, complications (including hypertension and diabetes mellitus), preoperative blood glucose, hemoglobin, serum creatinine, cardiac output, ejection fraction, pulmonary arterial systolic pressure, intraoperative cardiopulmonary bypass (CPB) time, transfusion of allogeneic red blood cells, and urine volume within 24 h after operation were recorded.The risk factors of which P values were less than 0.05 would enter the multivariate logistic regression analysis to stratify postoperative AKI-related risk factors for this type of patients.Results A total of 39 patients were enrolled in this study.Of the 39 patients, 14 patients suffered from AKI after operation, and the incidence was 36％.The results of logistic regression analysis showed that preoperative pulmonary hypertension and CPB time ＞ 180 min were the independent risk factors for AKI after cardiac transplantation.Conclusion Preoperative pulmonary hypertension and CPB time＞180 min are the independent risk factors for postoperative AKI in the patients undergoing cardiac transplantation.

OBJECTIVE:To optimize the factors of preparing pheophrobide from silkworm excrement and raise the yield of pheophrobide.METHODS:Based on the extraction rate of chlorophyll,acetone method was compared with alcohol method and the preparing factors of acetone method was optimized by orthogonal design.RESULTS:The best conditions for pheophrobide preparation included grinding silkworm excrement into powder with particle size all below 250μ m,softening the powder more then 5h with water 1/10 the volume of powder,extracting the powder with acetone three times the volume of powder at 70℃ for two times 60min each,regulating pH of the liquid to 2.5 with HCl solution.CONCLUSION:The water and acetone volume was more important than other factors,the yield of pheophrobide was raised 3.6 times after optimization

Objective To evaluate the clinical efficacy and safety of modified anti -tuberculosis scheme in the treatment of tuberculous meningitis.Methods 60 cases with tuberculous meningitis were randomly divided into two groups.We enrolled 30 patients in each group.The traditional anti -tuberculosis group used traditional anti -tuberculosis scheme with isoniazid,rifampicin,pyrazinamide,streptomycin,and the modified anti -tuberculosis group was given isoniazid,rifampicin,pyrazinamide,levofloxacin,the treatment course of tuberculous meningitis was 12 months.The efficacy and safety through clinical manifestations and laboratory examinations,the dynamic changes of cerebrospinal fluid were evaluated by statistical methods.Results The total effective rate of the modified anti -tuberculosis group was significantly higher than the traditional anti -tuberculosis group(86.6% vs.63.3%,χ2 =4.36,P <0.05).The cerebrospinal fluid routine and biochemical index in the modified anti -tuberculosis group were obviously superior to the traditional anti -tuberculosis group after treatment(all P <0.05).There was no significant difference in the incidence of adverse reactions between the two groups(26.6% vs.16.7%,χ2 =0.88,P >0.05).Conclusion Levofloxacin combined with other first -line anti -tuberculosis drugs,glucocorticoids,dehydration and other comprehensive measures improved brain function for the treatment of tuberculous meningitis is recommended.

OBJECTIVE:To explore the effect of Xiaoyu anshen capsule on the space learning-memory ability of chronic stress-induced depressed model rats.METHODS:The enrolled rats were divided into 6 groups:blank control group,model group,Fluoxetine group,Xiaoyu anshen capsule groups(high,medium and low dose).Chronic depression rat model was induced by chronic stress and isolated breeding.Water-maze video tracking analysis system was used to detect the capacity of rats' space learning-memory,and the indexes such as the body weight of rats before and after modeling and the consumption of sucrose,etc.were measured.RESUTLS:Compared with the blank control group,the model control group showed significantly decreased space learning-memory capacity,significantly lower in body weight increase and significantly less sucrose solution consumption.Compared with the model control group,the high,medium and low dose Xiaoyu anshen capsule-treated group showed significantly shortened escape latency,the high and medium dose groups showed increased number of times of crossing the hidden platform and body weight increase,and in high dose Xiaoyu anshen capsale group sucrose consumption increased.CONCLUSION:Xiaoyu anshen capsule is a nootropic Chinese herbal medicine for its inhibitory effect on the abnormality in body weight and sucrose solution consumption of chronic stress-induced depressed model rats and their action in enhancing the space learning-memory ability.
