Several reconstruction techniques are available after gastrectomy. Roux-en-Y reconstruction following distal gastrectomy is the reference in terms of long-term functional and endoscopic outcomes. It is the preferred reconstruction for benign lesions and early gastric cancer. In patients with advanced gastric cancer, BillrothII (reconstruction is an acceptable alternative. After total gastrectomy, Roux-en-Y reconstruction is the simplest solution, with satisfactory functional outcome. Addition of a jejunal reservoir seems to improve long-term outcome after total gastrectomy and could be of benefit to patients with good prognosis. After distal or total gastrectomy, hand-sewn anastomoses should be preferred because of lower costs. Mechanical sutures can facilitate transhiatal esophagojejunostomy. After proximal gastrectomy, esophago-gastric anastomosis is the basic reconstruction method. Gastric remnant is made into gastric tube in the operation. The effect of pyloroplasty remains controversial, and further study is needed to improve the quality of life after operation.

Objective To evaluate the clinical value of Nevin and AJCC staging system for gallbladder carcinoma. Methods In this study 90 patients diagnosed as gallbladder carcinoma underwent operation in Renji Hospital from February 2000 to October 2006. Patients were staged according to Nevin and AJCC staging system. The difference of survival rate, tumor resection rate, ratio of tumor-free resection margin and surgical procedures were analyzed. Results The survival rate, tumor resection rate and ratio of tumor-free resection margin decreased progressively with increasing Nevin and AJCC stage (P < 0. 05). There was no significant difference between the survival rate for Nevin Ⅲ or Ⅳ patients undergoing radical resection and simple cholecystectomy (P > 0. 05). In Nevin Ⅴ patients, the survival rate for radical and extensive radical resection patients was higher than for palliative patients (P < 0. 05). In AJCC Ⅲ patients, the survival rate for radical patients was significant higher than for palliative patients (P < 0. 05). Nosignificant difference was found between radical and palliative patients in survival time in AJCC Ⅳ (P > 0. 05). 52 patients in AJCC Ⅲ and Ⅳ were staged to Nevin Ⅴ according to Nevin staging system. The survival rate and resectable rate for the patients in AJCC Ⅲ were higher than in AJCC Ⅳ (P = 0. 0001, 0. 001 respectively). The rate of radical operation in AJCC Ⅲ was higher (P = 0. 001), and the rate of palliative operation in AJCC Ⅳ was higher (P = 0. 001). Conclusion Both Nevin and AJCC staging system are useful in the judgement of survival, reeectability, ratio of tumor-free resection margin and the optimal operation. AJCC staging system is more applicable for gallbladder carcinoma patients at advanced stage in terms of predicting prognosis.

China has high prevalence of gastric cancer, with the morbidity and mortality leading the list of malignancy. The conditions of diagnosis and treatment of gastric cancer in China fail to meet the need of a large number of patients because of restriction in re-gional development. Therefore, we are facing a very serious situation of fighting against gastric cancer. Multidiscipline, individualiza-tion, and standardization are the development tendency of diagnosis and treatment of gastric cancer. Numerous topics about gastric cancer are currently controversial and solutions to these problems depend on the development of evidence-based medicine. This re-view summarized the recent progress in the clinical methods used for stomach cancer, laparoscopic surgical techniques, diagnosis and treatment of early gastric cancer, conversion therapy of advanced gastric cancer, therapeutic strategy of esophageal-gastric junction cancer, enhanced recovery after surgery, and translational research and clinical trials of gastric cancer. Moreover, the foci and prob-lems of the diagnosis and treatment of gastric cancer were discussed to provide reference for further studies.

Cough is one of common respiratory symptoms in pediatric pulmonology.But there′s no practical pediatric guideline for diagnosis and management in particular an evidence-based one.This article introduces American College of Chest Physicians(ACCP) evidence-based clinical practice guidelines for evaluation chronic cough in pediatrics from which can be borrowed ideas.The introduction of ACCP guidelines for evaluation chronic cough in pediatric provided modified naming to previous diseases,discussed etiology of cough caused by different diseases and drew detailed flow charts for chronic cough diagnosis and management.

Objective: To optimize the formulation parameters of solid lipid nanoparticles (SLN) of Silymarin by Box-Behnken experimental design. Methods: A three-factor and three-level Box-Behnken experimental design was employed using emulsion evaporation-low temperature solidification technique to prepare SLN with Silymarin as model drug. Response surface methodology was used to investigate the factors affecting entrapment efficiency (EE), drug loading (DL), and particle size. Binomial mathematical model-optimized formulation was established with EE, DL, and particle size as response values. Results: The optimal formulation was as follows: the amount of glycerol monostearate was 5.05%, the concentration of Poloxamer 188 was 7.25%, and the amount of drug was 15%. Conclusion: The Box-Behnken experimental design could be used to optimize the SLN of silymarin.
