Objective:This study aims to investigate the method and clinical outcomes of feeding tube placement and periopera-tive nutritional support for esophageal carcinoma patients. Methods:A total of 513 esophageal carcinoma patients who have undergone radical resection and reconstruction by a single operating group between January 2012 and December 2013 participated this study. Feed-ing tubes were inserted via the nasal path of 497 cases and by jejunostomy in 16 cases. Early enteral nutrition (EN) was administered through the feeding tubes 24 h postoperatively with a stepwise increase, whereas supplementation of parenteral nutrition (PN) was ter-minated until total EN. Results:Feeding tubes were successfully inserted in all patients during operation. No death or nutritional and metabolic disorders were documented during the observation period. No differences in anastomotic fistula, pulmonary complication, and incision infection were identified between the nasointestinal and jejunostomy groups (P>0.05). A higher incidence of intestinal ob-struction was observed in the jejunostomy group than in the nasointestinal group (P<0.05). Conclusion:Effective placement of nasoin-testinal tube and early enteral feeding are safe and effective methods for patients who have undergone esophagectomy for esophageal carcinoma.

Objective To observe the therapeutic effect of traditional Chinese medicine(TCM)granules made by the formula of Shegan Mahuang decoction for treatment of patients with asthma. Methods A prospective study was conducted,51 cases of light to moderate asthma(cold type)patients were randomly divided into treatment group (25 cases)and control group(26 cases). Conventional symptomatic treatments were of the same in two groups. The patients in control group were given salbutamol aerosol inhalation,100μg each time,4 times per day;based on the treatment of the control group,additionally the above mentioned TCM granules dissolved in water was administered orally 1 dose/day taken twice once in the morning and another once in the evening in treatment group. The therapeutic course was 12 weeks in both groups. Before and after treatment,the asthma control test(ACT)score,forced expiratory volume in 1 second(FEV1)and peak expiratory flow(PEF)were observed. The therapeutic effect,adverse reaction and compliance were evaluated. Results The number of patients with asthma completely controlled in the treatment group was significantly higher than that in the control group(16 cases vs. 9 cases,χ2=4.82,P=0.028). In the patients of two groups,FEV1,PEF and ACT scores were significantly improved after treatment,and in the treatment group,they were obviously higher than those in control group〔FEV1(L):2.67±0.46 vs. 2.32±0.47,PEF(L/min):327.6±49.4 vs. 273.1±42.8,ACT score:22.8±2.0 vs. 21.1±2.6,all P<0.05〕. After treatment,FEV1%predicted value was increased in the treatment group but decreased in control group,there was significantly statistical difference〔(0.68±0.07)% vs.(0.80±0.11)%,P<0.05〕,no significant adverse reaction was found,compliance was good. Conclusion TCM granules made by formula of Shegan Mahuang decoction can improve the clinical symptoms, pulmonary function and control level in patients with asthma,so it is an effective medicine for the control of asthma.

Molecular imprinting technique (MIT) involves the synthesis of polymer in the presence of a template to produce complementary binding sites in terms of its size, shape, and functional group orientation. Such kind of polymer possesses specific recognition ability towards its template molecule. Despite the rapid development of MIT over the years, the majority of the template molecules that have been studied are small molecules, while molecular imprinting of proteins remains a significant yet challenging task due to their large size, structural flexibility and complex conformation. In this review, we summarize the research findings over the past five years, and discuss the characteristics of the technique, the most recent progress and the perspective in the field of molecular imprinting of proteins.
