The β-adrenergic receptor has close relationship with the occurrence and development of tumor.The β-adrenergic receptors were expressed in a variety of tumors.Its activation can stimulate tumor growth by promoting cell proliferation,inhibite apoptosis,promote angiogenesis,and enhance tumor invasion and metastasis.The β-adrenergic receptor blockers can suppress the tumor growth,which may become one of the effective methods of cancer prevention and treatment.

Objective To investigate the clinical treatment effect of tubular stomach substitute for esophagus anastomosis in the radical surgery of esophageal cancer.Methods Ninety-seven patients diagnosed with esophageal cancer in the First Affiliated Hospital of Soochow University from June 2013 to June 2015 were selected.They were divided into two groups,51 patients using the gastric tube substitute for esophagus anastomosis in the gastric tube group,and 46 patients using the traditional full stomach substitute for esophagus anastomosis in the whole stomach group.The operation times,intraoperative blood losses,the amount of postoperative gastrointestinal decompression,hospital stays,pathologic stages and incidences of complications after surgery in the two groups were observed and compared.Results There were no preoperative death in the two groups.The gastric tube group took more operating time than the whole stomach group [(287.43 ± 23.64) min vs.(266.13 ±26.47) min],with a significant difference (t =2.279,P =0.031).In the comparison of the amount of gastrointestinal decompression,the gastric tube group was less than the whole stomach group [(1 908.14 ±327.97) ml vs.(2 221.93 ± 323.87) ml],with a significant difference (t =-2.591,P =0.015).There were not significant differences in blood losses [(325.00 ± 64.30) ml vs.(356.67 ± 49.52) ml;t =-1.490,P =0.147],the numbers of lymph nodes [(10.73 ± 4.83) vs.(10.36 ± 5.31);t =0.238,P =0.813],hospital stays [(15.32 ± 3.69) d vs.(16.45 ± 3.80) d;t =-1.005,P =0.320] and pathologic stages (P =0.713) in the gastric tube group and whole stomach group.The incidence of gastroesophageal reflux in the gastric tube group was significantly less than that in the whole stomach group,with a significant difference (1.96％ vs.15.22％;x2 =5.617,P =0.025).The occurrence of the complications like anastomotic leakage (5.88％ vs.10.87％;x 2=0.795,P =0.471),postoperative pulmonary complications (13.73 ％ vs.23.91％;x2 =1.661,P =0.296)and anastomotic stenosis (7.84％ vs.13.04％;x2 =0.707,P =0.510) had no statistical difference in the gastric tube group and whole stomach group.Conclusion In the surgical treatment of esophageal cancer,tubular stomach substitute for esophagus anastomosis is better than the full stomach substitute for esophageal surgery,which can improve the life quality of postoperative patients and is worthy of clinical promotion.

Using Response Surface Methodology (RSM), an optimizing model of concurrent parameter and tolerance design is proposed where response mean equals its target in the target being best. The optimizing function of the model is the sum of quality loss and tolerance cost subjecting to the variance confidence region of which six sigma capability can be assured. An example is illustrated in order to compare the differences between the developed model and the parameter design with minimum variance. The results show that the proposed method not only achieves robustness, but also greatly reduces cast. The objectives of high quality and low cost of product and process can be achieved simultaneously by the application of six sigma concurrent parameter and tolerance design.

ObjectiveTo observe the clinical effect of acupuncture plus ice excitation on dysphagia in stroke patients.Methods60 stroke patients with dysphagia were divided randomly into treatment group (n=30) and control group (n=30). The treatment group received acupuncture plus ice excitation, while the control group only received acupuncture. The course was 4 weeks.ResultsThe curative effect showed that the total effective rate was 96.67% in the treatment group with recovery in 23 cases, improvement in 6 cases, and uselessness in 1 case, while the total effective rate was 73.33% in the control group with recovery in 17 cases, improvement in 5 cases, and uselessness in 8 cases (χ2=6.435, P＜0.05).ConclusionAcupuncture plus ice excitation had a good effect on dysphagia in stroke patients.

Objective To study the influence of HBV infection for gastromucous membrane in chronic hepatitis B and cirrhosis and its pathogenesis.Methods The liver biopsy,gastroscope,liver function and HBVM were detected at the same time in 60 patients with chronic hepatitis B and cirrhosis.HBsAg and HBcAg in the tissues of liver and gastromucous membrane were detected by SP immunohistochemistry.Results The damage of gastromucous membrane were found in 56 of 60 patients.Its damage degree was showed as moderate and severe.The other 34 showed mild and moderate damage(P

To develop a medication reminder based on Android platform, which can be used to set up personalized reminders quickly and record the patient' s medication time-stamp and related information. In addition, the effect of using the reminder on medication compliance was studied. 14 subjects participated in the evaluation of medica-tion compliance. The differences of dosage and medication rate between the group using and without using reminder were investigated. The dosage and medication rate were got by the pill counting. The Wilcoxon matched -pairs signed rank test showed that the dosage and the medication rate of the group using reminder were higher than that without using reminder significantly(Z= -2. 93, P =0. 003 ). The results demonstrated that the use of the re-minder can improve the medication dose and rate significantly,indicate that the reminder might be a new technical support for clinical research on medication compliance, and also might reduce the workload for medical staff and patients.

Objective To explore the immune function injury and its mechanism in drug abuser.Methods The immune function changes in 50 drug abusers were compared with normal healthy populations by detection of the indexes of subgroups of Th cells, transformation rate of lymphocytes,IgA,IgM,IgG,IgE,compliment C3,C4,IL 1, IL 2,IL 6 TNF and NO.Result In peripheral blood the percentage of Th1 cell, transformation rate of lymphocyte, IgA, IgM, IgG, IgE content, compliment C4,C4, IL 1, IL 2,IL 6,and TNF levels were significantly lower than normal(P< 0.01).The value of Th1/Th2 was lower than normal as well(P< 0.05).NO content was significantly higher than normal(P< 0.001).Conclusion The mechanism of immune function injury in drug abuser might be correlative to direct injury of drugs and their inhibition effect on the thymus hypothalamus hypophysis adrenal axis.

OBJECTIVE:To prepare silybin liposomes(SLBL)coated by N-trimethyl chitosan(TMC)(TMC60-SLBL),and to optimize the formula. METHODS:The effects of 3 kinds of preparation methods on encapsulation efficiency of SLBL were com-pared,including film dispersion method,multiple emulsion method and reverse evaporation method. The formula of TMC60-SLBL was optimized by orthogonal test using encapsulation efficiency as index with the concentration of phospholipid,ratio of phospholip-id to cholesterol,ratio of silybin to lipids,hydration temperature as factors. The stability of TMC60-SLBL by optimal formula at 4 and 25℃within 30 d,the particle size and Zeta potential of TMC60-SLBL and SLBL were all compared. RESULTS:The encapsu-lation efficiency of TMC60-SLBL prepared by the film dispersion method was the highest,without statistical significance in encap-sulation efficiency before and after cutting (P>0.05). The optimal formula was with the concentration of phospholipid 6 mg/ml;the ratio of phospholipid to cholesterol 40∶1;the ratio of silybin to lipids 1∶30;the temperature of hydration medium 45 ℃;the encapsulation efficiency were(82.08±2.6)%,RSD=3.17%(n=3). The preparation was stable at 4℃;the mean diameter of SL-BL and TMC60-SLBL were(131.9±1.9)nm and(161.2±2.0)nm,and Zeta potential respectively were(-23.18±1.14)mV and (36.73 ± 2.84) mV. CONCLUSIONS:TMC60-SLBL is prepared successfully,and its formula is simple and practicable with high encapsulation efficiency.
