Objective To evaluate the efficacy and safety of bortezomib combined with dexamethasone and thalidomide in the treatment of autologous stem cell transplantation ( ASCT) in multiple myeloma ( MM) . Methods The randomized con-trolled trials ( RCTs) on combined therapy with bortezomib,dexamethasone and thalidomide for ASCT in MM were retrieved from Pubmed,Medline,the Cochrane Library,CNKI,VIP and Wanfang databases (published until December 2014).The method of the Cochrane systematic review was used to evaluate the quality of the included RCTs and the Review Manager 5.3.5 software was em-ployed for Meta-analysis. Results Five RCTs involving 1 271 patients were included.The meta analysis results showed that the complete remission ( CR) rate,near-CR rate and total effective rate were significantly higher after combined treatment with borte-zomib,dexamethasone and thalidomide when compared with those in other combination therapies [CR+nCR, RR=1.50,95%CI (1.16,1.94),P=0.002;the total effective rate,RR=1.13,95%CI (1.03,1.24),P=0.009].In terms of safety,the grade 3/4 ad-verse events were significantly increased in the group of combined therapy with bortezomib,dexamethasone and thalidomide [ RR=1.29,95%CI (1.05,1.59),P=0.02]. Conclusion Bortezomib combined with thalidomide and dexamethasone for the treat-ment of ASCT in MM can significantly improve the CR+nCR and the total effective rate,but it also increases the incidence of the overall adverse events at the same time.

Objective To evaluate the reliability and validity of Chinese version of the Carlson's Prior Conditions Instruments(CPCI)for post-operative pain management practices of nurses.Methods With convenience sampling,a total of 200 surgical nurses were investigated with Chinese version Dimensions of Carlson's Prior Conditions Instruments (CPCI),and the reliability and validity were tested.Results Six factors were extracted by factor analysis and could explain 61.089％ of the total variance with the Chinese version of CPCI.The correlation between each sub-scale and total scale were ranged from 0.583～0.825.The Cronbach's α、split-half coefficient and test-retest reliability of PICI were 0.865、0.661、0.904 respectively.The Cronbach's α、split-half coefficient and test-retest reliability of each sub-scale were ranged from 0.772～0.860、0.678～0.830、0.822～0.946 respectively.Conclusions The revised Chinese CPCI is reliable and valid,and can be used in the research of prior conditions which may influence surgical nurses to take evidence-based pain management practices.

OBJECTIVE:To establish the ultraviolet visible spectrophotometry(UV-VIS)for the determination of Fe content in iron dextran preparations.METHODS:Under the acidic condition,Fe~(3+)was dissociated from iron dextran solution by heating,then Fe~(3+)was deoxidized into Fe~(2+)by hydroxylamine hydrochloride,and red Fe~(2+)-orthophenanthroline complex was formed through combination with o-phenanthroline.The content of the Fe~(2+)-orthophenanthroline complex was determined by UV-VIS at a wavelength of 510 nm.RESULTS:The linear range of Fe~(2+)was 0.5～4.0?g?mL~(-1)(r=0.999 9). The average recoveries of two preparations(tablets and injection)of iron dextran were 99.8%(RSD=0.52%)and 99.7% (RSD=0.44%),respectively.CONCLUSION:The UV-VIS method is simple,accurate in results and applicable for the determination of iron dextran preparations.

Stroke is a cerebrovascular disease type with high morbidity and mortality,of which ischemic stroke accounts for about 80％.Now,it is believed that the inflammatory mechanisms play an important role in the progress of pathological physiology of ischemic stroke.Peripheral T lymphocytes infiltrate to the damaged area within 24 hours after cerebral ischemia and are involved in the advance of inflammatory process of brain tissue.As a subtype of T lymphocytes,regulatory T cells are mainly located in the ischemic penumbra; however,at present,its role in ischemic brain injury remains controversial.The research on the mechanisms of regulatory T cells in ischemic stroke may contribute to further understanding of the pathogenesis of ischemic stroke and find new therapeutic targets.

Objective The questionaires of the ONFH aegers who were hospitalized in Kanggu hospital,during 2005-2008 ,were collect-ed to evaluate the therapeutic effects of acupotomy by proper statistical methods. Methods Four indexes according to the criteria of Therapeutic effect of adult ONFH recovery and reconstruction (ZHAO Dewei, 1996) were measured to evaluate the effect of the treatment. Results Monofac-torial analysis showed that the treatrnent was effective,but some phenomena could not be correctly explined in specialized field. This problem was re-solved appropriately by structural equation model(SEM). Conclusion By the method of SEM, the confounding factors could be better controlled and the evaluation was more reliable.

The severity of ischemic brain injury was closely associated with the mortality and disability of stroke. How to limit ischemic brain injm-y to the greatest extent and promote the recovery of neurological function is one of the most concerned hotspots at present in the field of neuroscience. A large number of studies have shown that a variety of factors involve in the pathological process of ischemic brain injury, in which, the role of T lymphocyte-mediated immune inflammatory response in ischemic brain injury has received increasing attention. This article mainly reviews the role of T cells in ischemic brain injury.

Objective To test the in vitro effect of the extract of Herba taraxaci on Demodex folliculorum. Methods Active Demodex folliculorum were obtained from patients with moderate to severe demodex infestation. Herba taraxaci and Radix stemonae were extracted respectively with 80% ethanol under 85℃, and a preparation with a concentration of 200mg/ml was made. The extractions were used in vitro to examine the anti-mite activity by observing time of killing mites. Physiological saline and Radix stemonae extraction served as blank control and positive control respectively. PH value of Herba Taraxaci extract was noted. Skin irritation test of normal and wounded skin and acute toxicity test were carried out with rabbit shin, and Herba taraxaci and 75% ethanol were served as experiment and control medicine. Results Motion and morphology of the mites considerably changed with the effect of Herba taraxaci extract. The time of mite-killing was (1.50?0.65)min with Herba taraxaci and (3.53?1.04)min with Radix stemonae respectively (P
