OBJECTIVE:To explore the implementation methods of drug price reform in China. METHODS:Current condi-tion and disadvantages of drug price mechanism in China were analyzed,the problems of the implementation of drug price reform were concluded and summarized,and the implementation methods of drug price reform were put forward. RESULTS & CONCLU-SIONS:Current condition and disadvantages of drug price mechanism in China are mainly reflected as failure of policy for maxi-mum retail price causes part of drugs to be overpriced;government-led centralized procurement of drugs results in that part of drugs are underpriced;the defects in the regulation of drug price addition rate leads to hospitals’procurement of drugs at higher price;government’s excessive interference in drug price affects the fair competition and sound development of pharmaceutical in-dustry. However,there are some problems for drug price reform,including unsound drug distribution system,a lack of fair compe-tition in modern drug market,excessive centralization of power of medical insurance authorities,absent public participation and so-cial supervision,and the“practice of using pharmacy profits to subsidize medical services”leading to wrong medical behavior. These measures were suggested to resolve above problems,i.g. reform the drug distribution system,foster modern drug market,es-tablish a medical insurance authorities-led mechanism for drug price negotiation in which multiple interest parties participate,and develop drug retail enterprises gradually replacing the outpatient pharmacies in hospitals to separate medical services from pharma-ceutical services.

Objective:To investigate the role of nuclear factor-?B(NF-?B)in rats with cerebral ischemia-reperfusion injury. Methods:Rat models of cerebral ischemia-reperfusion were established.24hours later,the expression of NF-?B in rat brain of sham-operation group,operation group and intervention group was detected with immunohistochemistry method,Cytokin-induced neutrophil chemotactics(CINC)in rat brain were measured and histopathological examinations were conducted on the hippocampal CAl.Results:The expression of NF-?B p65 and CINC in the operation group increased significantly compared with the sham-operation group(P

Objective: To investigate the effects of the tandem repeat polymorphisms in the enhancer region (ER) of thymidylate synthase (TS) gene and the 6-bp deletion/insertion (del6/ins6) polymorphism in the 3′ untranslated region (3′-UTR) of TS gene on the clinical outcomes of gastric cancer patients treated with 5-FU-based adjuvant chemotherapy. Methods: One hundred and sixteen patients with gastric cancer were treated with 5-FU-based adjuvant chemotherapy. The polymorphisms of TSER and TS 3′ -UTR in those patients were determined by polymerase chain reaction (PCR) method. Results: Of the 116 patients, the frequencies of the TSER 2R/2R, 2R/3R and 3R/3R were 7.8% (9/116), 31.9% (37/116), and 60.3% (70/116), respectively; the frequencies of the TS3′-UTR ins6/ins6, ins6/del6 and del6/del6 were 9.5% (11/116), 41.4% (48/116) and 49.1% (57/116), respectively. The median survival period in ins6/ins6 carriers was significantly shorter than that of del6/del6 (P = 0.017) or ins6/del6 (P = 0.022) carriers. There was no significant difference in median relapse-free survival period between different TSER carriers (P > 0.05). COX multivariate analysis showed that the ins6/ins6 carriers had increased death risk (P <0.05) compared to the other two genotypes. The median no-recurrence survival period had no statistical difference between them. Conclusion: The polymorphism of TS 3 UTR ins6/del6 may be an independent factor for the prognosis of gastric cancer patients treated with 5-FU-based adjuvant chemotherapy.

Aortic dissection has been remained highly lethal by far,especially for those involving the aortic arch.Many ways have been tried to tackle with aortic arch lesions including open surgery,endovascular therapy and hybrid procedure.Among them,surgical replacement of aortic arch seems to be the most promising on account of its long-term follow-up.However,there is still no uniform surgical procedure for aortic arch replacement.And surgical complications often occur due to its complex anatomical structures.Accordingly,many surgical procedures aiming at simplifying the procedure and lowering the risk of the operation have been raised.This article will introduce these new ways by reviewing related literatures and making brief comments.

Objective To ascertain and evaluate the quality of radiological protection in rural and urban primary health care institutions . Methods Questionnaires were designed to investigate the protection levels in diagnostic radiology in primary health care institutions in six cities in 2013 and to evaluate the results by using the technique for order preference by similarity to an ideal solution ( TOPSIS) combined with the rank sum ratio ( RSR) method.Results The six cities and an integrated case ( all the data of the six prefecture-level citys were merged as one for comprasion ) were ranked based on the comprehensive assessment.The order from good to bad was Suzhou , Dalian, Yichang, integrated case, Shaoxing, Quzhou and Heihe.The results were divided into three grades , with Suzhou, Dalian at best grade, Yichang, integrated case, Shaoxing, Quzhou at middle grade, and Heihe at poor grade. Conclusions The quality of protection in radiation diagnosis varied considerably .Suzhou ranked the first and Heihe ranked the last .The study suggests that efforts should be focused on the management of key cities and indicators to upgrade whole protection level in radiation diagnosis .

OBJECTIVE:To investigate the effects of atorvastatin combined with valsartan on efficacy,safety and related indi-cators in patients with chronic nephritis. METHODS:86 patients with chronic nephritis were randomly divided into control group (43 cases)and observation group(43 cases). All patients were given low-salt,low-protein and high-quality diet with protein intake of 0.8 g/(kg·d),appropriately given Cyclophosphamide tablet,Prednisone tablet,Penicillin V potassium tablet and other conven-tional treatment. Based on it,control group was given 160 mg valsartan,once a day in early morning. Observation group was addi-tionally given 20 mg atorvastatin,once a day before bedtime. They were treated for 6 months. Clinical efficacy,24 h protein amount (24 h pro),serum creatinine (Scr),blood urea nitrogen (BUN),glomerular filtration rate (GFR),C-reactive protein (CRP),total cholesterol (TC),triglyceride (TG ),low density lipoprotein (LDL) and high density lipoprotein (HDL) in 2 groups were observed,and incidence of adverse reactions was followed-up for 9 months. RESULTS:The total effective rate in ob-servation group was significantly higher than control group,the difference was statistically significant(P<0.05). Before treatment, there were no significant differences in 24 h pro,Scr,BUN,GFR,CRP,TC,TG,LDL and HDL between 2 groups(P>0.05). After treatment,24 h pro,Scr,BUN and CRP in 2 groups were significantly lower than before,and observation group was lower than control group,GFR was significantly higher than before,and observation group was higher than control group,the differenc-es were statistically significant(P<0.05). TC and LDL in 2 groups were significantly lower than before,HDL was higher than be-fore,the differences were statistically significant(P<0.05);but there were no significant differences in the TG between 2 groups and before and after treatment(P>0.05). And there was no significant differences in the incidence of adverse reactions between 2 groups (P>0.05). CONCLUSIONS:Based on the conventional treatment,the efficacy of atorvastatin combined with valsartan is superior to valsartan alone in the treatment of chronic nephritis,and it can significantly improve renal functions,with similar short-term safety.
