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 study the effect of roadside dust inhalable particulate matter on airway inflammation in rats.Methods:Particles at roadside were collected,analyzed and PM10-treat model of rats were established.Lung tissue histopathology was observed.The counts of total leukocytes and neutrophils in bronchoalveolar lavage fluid(BALF)and superoxide dismutase(SOD),glutathion peroxidase(GSH-Px),malondiadehyde(MDA),cytokin-induced neutrophil chemotactics(CINC)in lung homogenate were measured.Results:The counts of total leukocytes,macrophages and neutrophils in PM10-treat group were increased significantly than those in control group(P

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.

Intestinal microflora is a general term for microbial communities that reside in the human intestine. In recent years, the research on diseases related to intestinal microbiota has developed rapidly. It is found that intestinal microbiota is closely related to digestive tract diseases, metabolic diseases, immune diseases, mental diseases, and lung diseases. Intestinal dysbacteriosis, mucosal barrier damaging and local immune dysfunction may be involved in a variety of disease processes. In addition, respiratory diseases such as asthma and pneumonia seriously affect human health. The intestinal microbiota is crucial in regulating immune response of lung to pathological mechanism of diseases including asthma, pneumonia and pulmonary tuberculosis. Therefore, it may be a new direction for the treatment of lung diseases by understanding intestinal microbiota in lung diseases, and identifying, describing and manipulating immunity network of pulmonary disease.

From the beginning of the 20th century, Alois Alzheimer, a German doctor, discovered Alzheimer′s disease, so far, the isease-related research has been the focus of researchers all over the world. From Alzheimer's disease to mild cognitive impairment, then to subjective cognitive impairment, the attention phase of the disease is also being advanced. Subjective cognitive impairment, as a stage earlier than mild cognitive impairment, has important implications for the early diagnosis and intervention of Alzheimer′s disease.This article will summarize the research progress of conception and screening instruments for subjective cognitive impairment at home and abroad.

OBJECTIVE To investigate the infection conditions of human papillomavirus-16(HPV-16) and-18(HPV-18) in 382 healthy women and 118 uterine cervicitis and vaginitis women.METHODS Fluorescent quantitative polymerase chain reaction(FQ-PCR) was used to detect HPV-16 and HPV-18 in 382 healthy women and 118 uterine cervicitis and vaginitis women.RESULTS In 382 healthy women,two samples were HPV-16 positive,and one sample was HPV-18 positive,with 0.52% and 0.26%,respectively.In 118 uterine cervicitis and vaginitis women,eight samples were HPV-16 positive,and three samples were HPV-18 positive,with 6.78% and 2.54%,respectively.This study made a comparison of the positive rate of HPV-16 and HPV-18 between healthy women group and uterine cervicitis and vaginitis women group.There were marked differences between these two groups(P

Objective To analyze the relationship between renal function impairement and obesity in patients with primary hypertension.Methods One hundred and twenty-eight primary hypertension patients with renal function impairement admitted to our hospital from January 2012 to December 2015 were divided into obesity group (n=68) and control group (n=60) according to the Asian obesity diagnosis criteria established by the International Diabetes Federation.Relationship of serum urea nitrogen (BUN),creatinine,cystatin C (Cys-C),urinary N-acetyl beta-D glucosaminidase (NAG),urinary micro albumin levels and BMI with renal function impairment in primary hypertension patients was analyzed by multivariate linear stepwise regression analysis.Results The BMI,serum levels of urinary NAG,Cys-C,BUN,and creatinine were significantly higher in obesity group than in control group (31.70±1.80 kg/m2 vs 23.95±2.00 kg/m2,19.34±1.40 U/L vs 14.92±1.31 U/L,0.69±0.06 mg/L vs 0.47±0.05 mg/L,11.50±2.90 mmol/L vs 8.60±1.90 mmol/L,159.50±10.40 μmol/L vs 148.90±10.70 μmol/L,P＜0.05).The incidence of urinary micro albumin was significantly higher in obesity group than in control group (79.4％ vs 46.7 ％,P＜ 0.01).Blood pressure,pulse pressure difference,BMI,fasting blood glucose,serum levels of ereatinine,urinary NAG,Cys-C,BUN and urinary micro albumin were the risk factors for renal function impairement in primary hypertension patients (P＜0.05,P＜0.01).Conclusion Renal function impairement is related with obesity in primary hypertension patients.
