Fabrication of titanium carburizing electrodes for capacitive deionization.

Titanium carburizing electrodes were used as the electrodes in a capacitive deionization (CDI) process for desalination in this study. Two methods of high vacuum magnetron sputtering and chemical deposition were used for the preparation of nano-titanium carburizing electrodes (named Ti-C* and Ti-C**). By comparing the adsorption capacities of different kinds of electrode material, combined with physical and chemical characteristics and electrochemical analysis, the method of high vacuum magnetron sputtering to prepare Ti-C* electrodes have been proved successful for the CDI process. The results show that under the same conditions, the adsorption capacity of Ti-C* and Ti-C**were 9.6 mg/g and 7.12 mg/g, respectively. The Ti-C* electrodes showed a higher ion electrosorption capacity than Ti-C** and the electrodes can be easily regenerated, indicating excellent recyclability. This study provided a novel method to fabricate titanium carburizing electrodes in CDI process and might lead to the improvement of the CDI desalination performance in an industrial practical application.

Effects of S-1 Combined with Radiotherapy in the Treatment of Nasopharyngeal Cancer: A Meta-analysis Based on Randomized Controlled Trials.

The aim of this meta-analysis was to evaluate the effects and toxicity of S-1 combined with radiotherapy in the treatment of nasopharyngeal cancer (NPC). Through a search of the databases of PubMed, Embase, the Chinese Biomedicine Database (CBM), China National Knowledge Infrastructure (CNKI), Wanfang system and Chongqing VIP Information (CQVIP), the efficacy and side effects data of S-1 combined with radiotherapy in the treatment of NPC patients from open published randomized controlled trials (RCTs) were collected. The pooled complete response (CR), partial response (PR), objective response rate (ORR), 2-year survival rate and treatment related toxicity were analyzed by Stata12.0 software. Eight RCTs with 599 cases were included and analyzed in this meta-analysis. The general quality of the 8 studies were deemed as having moderate risk of bias. Adequate sequence generation was reported in 4 studies. Incomplete outcome data address was reported in 7 publications. Five studies indicated to be free of selective reporting. Seven studies reported the treatment complete response (CR) between S-1 combined with radiotherapy and radiotherapy alone. With significant heterogeneity, the data was pooled by random effect model. The pooled results indicated that S-1 combined with radiotherapy can significant increase the CR rate compared to radiotherapy alone (RR=1.52, 95%CI:1.33-1.74, P<0.05). Eight studies reported the partial response (PR) rate between the combined treatment and radiotherapy alone. The pooled results showed that there was no statistical difference for PR between combined treatment and radiotherapy alone (RR=0.85, 95%CI:0.62-1.16, P>0.05). For the effect size of objective response rate (ORR), pooled results indicated that S-1 combined with radiotherapy can significantly increased the ORR by random effect model (RR=1.39, 95%CI:1.23-1.57, P<0.05). The pooled results showed that S-1 combined with radiotherapy significant increase the risk of developing bone marrow suppression (RR=1.94, 95%CI:1.40-2.69, P<0.05) and gastrointestinal reaction (RR=1.81, 95%CI:1.38-2.38, P<0.05) with fixed effect model. However, the pooled oral mucositis (RR=1.22, 95%CI:0.99-1.50, P>0.05) and radiodermatitis (RR=0.93, 95%CI:0.77-1.12, P<0.05) were not statistically different. Two studies reported the 2-year survival rate between the two groups. The pooled results showed the combined treatment significantly increased the 2-year survival rate for patients with nasopharyngeal carcinoma (RR=1.14, 95%CI:1.01-1.28, P<0.05). The funnel plot demonstrated significant publication bias for complete response, partial response, objective response rate and oral mucositis. The egger's line regression test indicated significant publication bias for complete response (t=5.98, P=0.002) and objective response rate(t=6.23, P=0.003). Conclusion S-1 combined with radiotherapy can significant improve the clinical efficacy with more treatment related toxicity compared to radiotherapy alone in the treatment of nasopharyngeal carcinoma.

Curative efficacy of batroxobin combine with ginkgo injection in treatment of Sudden deafness and its effects on Serum ET、NO、SOD、sVCAM-1 / 中国生化药物杂志

Objective To study the effect of batroxobin combined with Yinxingdamo injection on serum endothelin(ET),nitric oxide(NO),superoxide dismutase(SOD),vascular cell adhesion molecule-1(VEGF-1)in patients with sudden deafness(SVCAM-1),to explore the best treatment for patients with sudden deafness.Methods Ninety patients with sudden deafness from June 2014 to June 2015 were recruited as the subjects of this study.The patients in control group were treated with batroxobin and batroxobin and ginkgo dipyridol.The levels of serum ET,NO,SOD,sVCAM-1,time of symptom recovery and the curative effect were observed.Results After treatment,the levels of ET,NO and sVCAM-1 in the observation group were significantly lower than those in the control group [(64.28±5.72)pg/mL vs(67.36±6.31)pg/mL,(43.08±9.53)μmol/(93.24±11.25)NU/mL](P<0.05).The results showed that there was no significant difference between the two groups.The recovery time of tinnitus,auria and vertigo in the observation group were less than those in the control group [(3.86±1.02)d vs(5.97±1.34),(5.03±1.24)d vs(7.37±2.01)d,(8.09±2.10)d vs 9.07±2.37)d](P<0.05).The total effective rate in the observation group was better than that in the control group(93.33％vs 75.55％,P<0.05).Conclusion Batroxobin combined with ginkgo dipyridolum injection can decrease the level of ET,NO and sVCAM-1,improve the level of SOD,and improve the microcirculation of the inner ear.Compared with the single effect of Batroxobin More desirable,worthy of promotion.
