Objective:To investigate the effects of oxaliplatin (OXA) and teniposide (VM-26) on proliferation and apoptosis of gastric cancer cell line BGC-823.Methods:MTT assay was used to examine the inhibition rate of cell growth when cells were treated at various concentrations of OXA and VM-26 alone or in combination. The apoptosis was examined by flow cytometry (FCM). The protein expression of cell apoptosis associated proteins caspase-9 and livin were examined by immunocytochemistry. Results:OXA or VM-26 effectively inhibited the growth of BGC-823 gastric cancer cells in a concentration-dependent manner at certain range of concentrations. The inhibitory rate of combined treatment with OXA and VM-26 was significantly higher than that of OXA or VM-26 alone (P<0.05). The value of combination index (CI) was 0.46. The rate of apoptosis cells induced by 1.25 μg/mL OXA was 6.13%, 13.86% and 21.48% at 12, 24 and 48 h. The apoptosis rate induced by 0.625 μg/mL VM-26 was 4.60%, 10.72% and 17.07% for 12, 24 and 48 h. In combined treatment group the apoptosis rate was 11.73%, 24.14% and 44.75% at 12, 24 and 48 h, respectively. The difference was significant between combined treatment group and single drug treatment group (P<0.05). Immunnocytochemical analysis showed that the expression of caspase-9 protein was up-regulated after being exposed to OXA (1.250 μg/mL) or OXA plus VM-26 (0.750 μg/mL), while the expression rate of livin protein was down-regulated. There were significant differences among different treatment groups as well as between treatment groups and control group (P<0.05).Conclusion:OXA combined with VM-26 has synergistic effects in inhibiting the growth and inducing apoptosis of gastric cancer BGC-823 cells.

Objective To analyse the economies of scale in public hospitals in Zhejiang Province. Methods One hundred and twenty-five public hospitals in Zhejiang Province with qualification no less than class two level two were selected as sample hospitals. Douglas production function was employed to analyse the relationship between investment and output in sample hospitals between 2004 to 2006, with two types of production models established by medical service and incomes in hospitals as dependent variables. Results From 2004 to 2006, the medical service and incomes of sample hospitals were in line with economies of scale. The production increase rate was higher than investment increase rate. The medical service, incomes, total assets and number of staff in class three hospitals were higher than those in class two hospitals (P =0.000). Conclusion Economies of scale is the ultimate incentive to continuous outstretch for hospitals. Hospitals should rationally control the scale so as to avoid problems in medical service caused by overstretch.

Objective To study the effect of neural stem cell transplantation on neurological behavior and expressions of Caspase-3 and Caspase-9 in rats with traumatic brain injury (TBI). Methods A total of 108 SD rats were randomly divided into the sham group (n=36), traumatic brain injury group (TBI, n=36) and neural stem cell transplantation group (NSC, n=36). TBI model of rats was established by using improved Feeney method. Rats of NSC group were injected neural stem cells in cortex after traumatic brain injury was established for 1 week, and then nurological severity scores (NSS) of rats were evaluated at 7 days, 14 days and 21 days after cell transplantation in TBI and NSC groups, respectively. Rats of sham group were only cut the scalp and exposed the skull without striking. The expressions of Caspase-3 and Caspase-9 in brain tissues were detected by immunohistochemistry and Western blot method. Results Compared with NSC group at the same time points, NSS was decreased significantly in TBI group (P<0.01). Compared with the sham group, the optical density (OD) values of Caspase-3 and Caspase-9 positive expressions were increased significantly in TBI group (P<0.05). Compared with TBI group at the same time points, the OD values of Caspase-3 and Caspase-9 positive expressions were decreased significantly in NSC group (P<0.05). Conclusion The neural stem cell transplantation can promote the recovery of brain injury by down-regulating the expressions of Caspase-3 and Caspase-9.

Objective:To explore the influence of diabetic self-management education on blood glucose control and inflammatory factor levels in inpatients with diabetes mellitus (DM).Methods:A total of 168 DM patients,who hospitalized in department of endocrinology in 163rd hospital of Chinese PLA from Jun 2012 to Jun 2013,were ran-domly divided into self-management education group (self-management group,n=88)and routine health education group (routine management group,n = 80).Self-management group received self-management education course namely AADE7TM ,provided by full-time DM health education staff,including healthy eating,being active,monito-ring,taking medication,problem solving,healthy coping and reducing risks,while routine management group re-ceived routine DM health education.Blood glucose control,changes of levels of myeloperoxidase (MPO),tumor necrosis factor-α(TNF-α)and intercellular adhesion molecule-1 (ICAM-1)were examined before and after interven-tion.Results:Compared with before intervention,there were significant reductions in levels of fasting blood glucose (FBG),postprandial blood glucose (PBG)and glycosylated hemoglobin (HbA1c)in both groups after interventions (P <0.05 all).Compared with routine management group,there were significant reductions in levels of FBG [(7.1 ±1.3)mmol/L vs.(6.0±1.1)mmol/L],PBG [(9.5±1.6)mmol/L vs.(8.8±1.4)mmol/L]and HbA1c [(7.9 ±1.5)% vs.(7.2±1.1)%]in self-management group,P <0.05 all.Before discharge,there were significant de-crease in inflammatory factor levels in both groups compared with before intervention (P < 0.05 all).Compared with routine management group after intervention,there were significant decrease in inflammatory factor levels [TNF-α:(201.0±57.3)pg/ml vs.(100.7±49.2)pg/ml,ICAM-1:(25.2±3.6)ng/ml vs.(18.2±2.9)ng/ml] in self-management group,P < 0.05 both.Conclusion:Self-management education provided by full-time diabetic health education staff is superior to routine diabetic health education method in controlling blood glucose and decrea-sing inflammatory factor levels,indicating it can improveβcell function and relieve insulin resistance.

Objective To establish the evaluation system and explore the possible impact factors for public interest nature in public hospitals. Methods One hundred and twenty-five public hospitals in Zhejiang Province were served as sample hospitals, and related data of year 2004 to year 2006 were collected. The Delphi expert investigation method, variation coefficient method and TOPSIS method were employed to screen the impact factors for public interest nature and build up the evaluation system for public hospitals, and stepwise regression analysis was conducted for possible impact factors of public interest nature. Results The evaluation system mainly included five aspects of quantity, quality, efficiency, mean charge of medical service and social satisfaction to public hospitals. The two most important factors that influenced the public interest nature were the number of beds and the number of equipments valued above 10 000 RMB. Conclusion The hospital scale is the most important impact factor for the nature of public interest in public hospitals. Therefore, the scale of public hospitals should be properly designed so as to ensure the public interest nature in public hospitals.

Biomechanical evaluation of neck muscles has important significance in the diagnosis and treatment for cervical spondylosis, the neck muscle strength and soft tissue stiffness test is two aspects of biomechanical testing. Isometric muscle testing operation is relatively simple, the cost is lower, which can evaluate the muscle force below grade 3. However, isokinetic muscle strength testing can assess the muscle strength of joint motion in any position. It is hard to distinguish stiffness difference in different soft tissues when the load-displacement curve is used to evaluate the local soft tissue stiffness. Elasticity imaging technique can not only show the elastic differences of different tissues by images, but also quantify the elastic modulus of subcutaneous tissues and muscles respectively. Nevertheless, it is difficult to observe the flexibility of the cervical spine by means of the analysis of the whole neck stiffness. In a word, a variety of test method will conduce not only the biomechanical evaluation of neck muscles, but also making an effective biomechanics mathematical model of neck muscles. Besides, isokinetic muscle testing and the elasticity imaging technology still need further validation and optimization before they are better applied to neck muscles biomechanical testing.
