Objective:To systematically evaluate the efficacy and safety of neoadjuvant chemoradiotherapy (NCRT) plus surgery versus neoadjuvant chemotherapy (NCT) plus surgery in the treatment of advanced esophageal squamous cell carcinoma.Methods:Clinical controlled trials of comparing the treatment of NCRT plus surgery with NCT plus surgery for esophageal squamous cell carcinoma were electronically searched from the databases including PubMed, The Cochrane Library, EMbase, CBM, CNKI, WanFang and VIP from the inception of databases to January, 2019. Two reviewers independently screened the literatures, extracted data and assessed the risk of bias of the included studies. And then, a meta-analysis was performed by using RevMan 5.3 software.Results:A total of 8 clinical control studies were included, including 995 patients with esophageal squamous cell carcinoma. Meta-analysis results showed that compared with the NCT group, the R 0 resection rate was significantly higher ( OR=2.14, 95% CI: 1.03-4.45, P=0.040) and the pathological complete response (pCR) rate was significantly higher ( OR=4.19, 95% CI: 1.71-10.28, P=0.002) in the NCRT group. The incidence of postoperative complications ( OR=1.37, 95% CI: 0.76-2.48, P=0.300) and the risk of perioperative death ( OR=1.28, 95% CI: 0.58-2.83, P=0.54) were not significantly different between two groups. The long-term survival of patients with esophageal squamous cell carcinoma in the NCRT group was significantly better compared with that in the NCT group ( HR=0.77, 95% CI: 0.64-0.92, P=0.005). Conclusions:Compared with NCT plus surgery for advanced esophageal squamous cell carcinoma, NCRT plus surgery has higher R 0 resection rate and pCR rate, does not significantly increase the risk of perioperative complications or perioperative death, and significantly improves the long-term survival of esophageal squamous cell carcinoma patients.

OBJECTIVETo compare the therapeutic effect differences between electroacupuncture at Jiaji (EX-B 2) combined with blood-letting plus cupping and western medicine therapy.

METHODSFifty-three cases were randomly divided into an observation group (n=31) and a control group (n=22). The observation group was treated by electroacupuncture at Jiaji (EX-B 2) combined with blood-letting with a plum-blossom needle at the affected parts plus cupping, once each day. The control group was treated by oral administration of Valaciclovir Hydrochlordide, Indomethacin, Vitamin B1 and Vitamin B12.

RESULTSThe cured and markedly effective rate of 96.8% in the observation group was better than that of 81.8% in the control group (P < 0.05), and improvements of pain, pruritus, burning sensation and sleep in the observation group were superior to those of the control group (all P < 0.01).

CONCLUSIONElectroacupuncture at Jiaji (EX-B 2) combined with blood-letting and cupping is a better therapy for herpes zoster and its therapeutic effect is better than that of routine western medicine therapy.

Objective To explore the outcome of brain derived neurotrophic factor(BDNF) and parvalbumin (PV) positive neurons after hyperbaric oxygen intervention for the valproic acid(VPA) autism rats in hippocampal CA1 region.Methods The animal model of autism was established by the methods of Schneider and Przewlocki.Animal model groups of autism were obtained in male offspring of the Wistar rats that received intraperitoneal injection of 600 mg/kg VPA on the 12.5 day after pregnancy according to the eye opening time,behavior,weaning weight and the learning and memory abilities which were evaluated by the Y electricity maze test on the 28th day after birth.Forty-eight male VPA autism rats were randomly divided into high-pressure high-oxygen group,high-pressure air group and normal pressure high-oxygen group and normal pressure air group(n =12,each group).Normal control group was obtained in male offspring of Wistar rats that received intraperitoneal injection of equivalent physiological saline in the same period (n =12).Using the immunohistochemistry methods and image analysis to examine the number of BDNF and PV positive neurons in hippocampal CA1 region of different groups.Results The number of BDNF positive neurons in normal pressure air model group was more than that in the normal pressure air control group,with statistical difference between them(5.00 ± 1.60 vs 3.00 ± 1.04,t =3.633,P =0.001).The number of the PV positive neurons in the normal pressure air model group was more than that of the normal pressure air control group,with statistical difference between them (5.33 ± 0.99 vs 2.83 ± 1.29,t =5.369,P =0.000).The number of the PV positive neurons in the high-pressure high-oxygen group was less than that in the normal pressure air model group,with statistical difference between them (3.33 ±0.99 vs 5.33 0.99,t =4.975,P =0.000).The number of the PV positive neurons in the high-pressure highoxygen group was less than that in the high-pressure-air model group (3.33 ± 0.99 vs 4.67 ± 1.92,t =-2.138,P =0.044).Conclusions The pathogenesis of autism may be related to the expression level of BDNF and PV in the hippocampal CA1 region and this may serve as the mechanism of hyperbaric oxygen intervention of autism animal model for effective treatment.

Esomeprazole sodium is a widely used proton pump inhibitor which is mainly applied to the treatment of gastric ul-cer,duodenal ulcer,digestive esophagitis and gastritis. By reviewing the literature over the past decade on the asymmetric oxidation of esomeprazole sodium ,the paper summarizes the synthetic process and focuses on the comparison of the critical steps. To choose suit-able chiral catalyst to reduce the cost of synthesis of esomeprazole sodium,this paper compares beyond the yield,enantioselectivity and other aspects. The conclusion is that the catalysts used in the most of oxidation systems are with a large load and high cost ,and compared with the classical Kagan-Modena system,the Ti-salan catalyst has advantages in the synthesis of esomeprazole sodium,and can be widely used.

Objective To comprehensively evaluate the clinical efficacy,safety and economic benefits of atorvastatin and fluvastatin in regulating dyslipidemia.Methods The clinical randomized controlled trials (RCTs) for comparing clinical efficacy of atorvastatin and fluvastatin on regulating dyslipidemia were retrieved from databases,including Cochrane Library,PubMed,Medline,Embase,Wiley,Springer,CNKI,Wanfang and VIP,till June 2016.Data were evaluated by two reviewers independently according to the Jadad standard.The changes of low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C),total cholesterol (TC) and triglyceride (TG) before and after treatment were extracted to perform Meta-analysis by using RevMan5.0 software.The economic evaluation was carried out,as well.Results A total of 7 RCTs were included,including 684 cases of patients treated with fluvastatin and 2 208 cases of patients treated with atorvastatin.The patients were spitted into two subgroups according to the same or different maximum dose of atorvastatin and fluvastatin.The results indicated that the effects of atorvastatin on down-regulating LDL-C,TC and TG levels were significantly better than those of fluvastatin,the differences were statistically significant (Z=23.63、23.32、5.50,P＜0.000 01).No significant difference was found in regulating HDL-C level between atorvastatin and fluvastatin.Conclusion Compared with fluvastatin,atorvastatin is more effective to regulate levels of LDL-C,TC and TG,but there is no significant difference in up-regulating HDL-C level.Additionally,application of atorvastatin is more economicallv effective.

Objective To investigate the effects of down-regulated miR-9 expression on ultraviolet rays (UV)-induced reactive oxygen species (ROS) damage in nasopharyngeal carcinoma (NPC) cells.Methods The NPC cells were transfected with inhibitors of miR-9 by lipofectamine to decrease the expression of miR-9,and the cells transfected with inhibitor control as the control.ROS levels following UV exposure were examined with DCF-DA method and the concentration of glutathione was analyzed via the benzoic acid method; DNA damage and apoptosis also were evaluated.Results There was significant difference in ROS levels between miR-9 expression-inhibited cells and control cells (26 895 ± 218 vs 15 765-±927,t =39.754,P ＜0.001),and also there were significant differences in DNA damage rates (28.0％ ± 10.0％ vs 23.6％ ±9.2％) and in apoptosis rates (8.0％ ±0.9％ vs 4.5％ ±0.8％) following UV exposure between two groups of cells.The miR-9 expression-inhibited cells showed lower level (1.87 ± 0.15) μmoL/L of glutathione compared with the control cells (9.85 ± 0.15) μmol/L (t =-48.832,P＜0.001).Conclusion Inhibition of miR-9 expression promoted UV-induced ROS damage in nasopharyngeal carcinoma cells.

Objective: To understand the present situation of physical activity and its influencing factors, and to provide a reference for improving the level of physical activity and making the intervention measures. Methods: The method of random stratification was used to select 4 740 pre school children aged 3-6 from 17 kindergartens in 12 counties and districts of Nanchang City, The questionnaire of physical activities of young children and the questionnaire of parents of physical activities of young children were applied to conduct a survey. Results: Compared with weekday PA and MVPA, preschool children’s weekends decreased, SB increased. The differences in PA, MVPA and SB on weekdays and weekends were statistically significant( P <0.01). The proportion of PA and MVPA reaching the recommended amount during the working day of preschool children were 44.9%-59.2%, 45.4%- 61.7%.The proportion reaching the recommended amount of PA and MVPA on weekends were 24.7%-27.8%, 24.5%-29.9%, and the proportion reaching the recommended amount on weekdays was higher than that on weekends. Conclusion There is still gap between actual amount of physical activity and the recommended amount. There are different modes of activity on weekdays and weekends, and weekends are the least active periods. Parents and teachers should pay enough attention to the establishment of "social campus family" model to improve the lack of physical activity of preschool children.
