Objective　To investigate the relationship between soluble tumor necrosis factor receptors (sTNF-R), TNF-α, TNF-α/sTNF-R and rheumatoid arthritis. Methods　 Serum levels of sTNF-RⅠ, sTNF-RⅡ and TNF-αwere measured in 28 patients with active RA and 12 patients with inactive RA and 30 healthy controls, using double antibodies sandwiched ELISA. Results　The results showed that serum levels of sTNF-RⅠ, sTNF-R Ⅱ and TNF-α　were significantly higher in the group of patients with active RA than those　found　in healthy group and　in the patients with inactive RA. Serum levels of both sTNF-RⅠ, sTNF-RⅡ and TNF-α　were also significantly higher in patients with inactive RA than in healthy group(P＜0.01 for all). In RA, the serum concentrations of sTNF-RⅠ and sTNF-RⅡ were positively correlated with the levels of ESR，CRP，Ritchie index. Conclusions　These results suggest that the serum levels of sTNF-RⅠ and sTNF-RⅡwere significantly increased and positively correlated with the disease activity. The determination of serum levels of sTNF-RⅠ and sTNF-RⅡ can be regarded as a useful laboratory parameter for diagnosis of RA,monitoring of the disease activity and assessment of prognosis.

Objective:To explore role of sodium/chloride transporter member 3 (SLC12A3 ) gene haplotype mutation on Mongolians with essential hypertension (EH) .Methods:A total of 170 EH Mongolians (EH group) and 220 normotensive Mongolians (normotensive group) specimens were collected from Xilin Gol league .Mononucleotide sites (tagSNP) were se-lected using Haploview software ,genotypes were divided using real-time polymerase chain reaction (PCR) and SHESIS on-line analysis software was used to establish haplotype .Results:(1) Body mass index (BMI) ,blood lipids (except high den-sity lipoprotein cholesterol ) and blood pressure of EH group were significantly higher than those of normotensive group , P<0.01;(2) A total of nine tagSNPs were screened from frequent polymorphic mononucleotides (SNPs) of SLC12A3 gene ,and there existed strong linkage disequilibrium (D′> 0.8) in three polymorphic sites (rs2289009 ,rs13306673 and rs7204044 ) .These three polymorphic sites constituted four frequent haplotypes with frequency >3% in total ,and frequen-cy of haplotype GCA in EH group was significantly lower than that of normotensive group (9.4% vs .16.6% ) ,OR=0.52 ,95% CI 0.33~0.84. Conclusion:There is relationship between GCA haplotype of SLC12A3 and hypertension in Mongolians ,individuals with GCA haplotype have a lower risk of hypertension .

MiRs display an important role in a variety of biological, physiological and pathological processes, including cell proliferation, differentiation, apoptosis, individual development, occurrence and progress of diseases. Recent studies have discovered that miR?424 is the significant regulatory factor of angiogenesis, and is involved in many diseases such as infectious diseases, vascular diseases, central nervous system diseases and genital system disease. This article reviews the expression, effect and possible mechanisms of miR?424 in non?tumorous diseases.

A member of miR-16 family, miR-424 has been found to be closely related with tumorigenesis, tumor progrssion, prognosis and therapy.This article reviews the expression changes, roles and possible regulating mechanisms of miR-424 in leukemia and various tumors such as breast, cervical, lung, liver and colorectal cancers.Recent studies have demonstrated that the expression of miR-424 is affected by many factors, and miR-424 could be a biomarker of diagnosis, staging and prognosis in cancers,to identify the area of tumor, and be a target of therapy.

Objective To explore the relationship between platelet to lymphocyte ratio (PLR) and microangiopathyin type 2 diabetes mellitus. Methods In this case-control study, the clinical data on 428 adult patients with type 2 diabetic microangiopathy in our hospital from January 2009 to December 2015 were retrospectively analyzed. PLR, age, sex, fasting blood glucose, glycosylated hemoglobin, total cholesterol and triglyceride were tested to investigate their relationship with type 2 diabetic microangiopathy. Results Logistic regression analysis showed that PLR was a risk factor of type 2 diabetic microangiopathy (OR = 3.162, 95%CI:1.556 ~ 7.421, P < 0.05). Conclusions Greater PLR is closely related to type 2 diabetic microangiopathy, and we should pay attention to type 2 diabetic microangiopathy with a greater PLR in clinical practice.

BACKGROUND: Malnutrition and overnutrition are the two problems during growth and development of high-school students.OBJECTIVE: To understand the situation and relevant factors of malnutrition and overnutrition of high-school students.DESIGN: Transverse investigation was designed.SETTING: Health Supervision Institute of Chongqing Health Bureau; Department of Nutrition & Food Hygiene, Chongqing University of Medical Sciences; the Eighth Middle School of ChongqingPARTICIPANTS: Totally 896 students in 15 classes were collected from one full-time middle school in Shapingba district in Chongqing by cluster sampling method from March to May 2004. The students were excluded if they suffered from hereditary metabolic disease and secondary pathological malnutrition or obesity due to trauma or other diseases. All of participants were in the known in the investigation. Of those, 826 students filled up the questionnaire in detail (the effective rate was 92.19%), in which, 414 students were male and 412 students female, aged varied from 13 to 18 years.METHODS: The students chose were in the investigation with questionnaire and the contents of it included basic physical situation, state of sickness, situation of parents, dietary behavior, nutritional knowledge, dietary habits, etc. The students filled up the questionnaire by them own and handed over on the spot. The evaluation of student nutrition state adopted the heights and body masses in recent physical examination scale, in reference to the criteria in "height and body mass of Chinese students aged from 7 to 22 years". The standard body mass was 80% of body masses of people with same height, based on which, the standard body mass was 100%, that less than the standard by 90% was taken as malnutrition and more than it by 120% was taken as obesity. Non-conditional logistic stepwise regression was used to analyze the data so as to probe into the factors of malnutrition and obesity in middle-school students.MAIN OUTCOME MEASURES: [1] Morbidity of malnutrition and obesity in middle-school students. [2] Factors of malnutrition and obesity in middle-school students.RESULTS: Totally 826 students entered result analysis. [1] Morbidity of malnutrition and obesity: it was 9.44% and 24.21% respectively, in which,the morbidity of malnutrition.for female was higher than male [4.84%,14.08% (x2=15.1036, P ＜ 0.05)] and the morbidity of obesity in male was higher than female [30.09%, 18.2% (x2=10.5737, P ＜ 0.05)]. [2] Factors of malnutrition and obesity: significant correlation was present between malnutrition and 5 factors, named sex, indulgence in or being choosy food,sleeping time, breakfast and animal internal organs (P ＜ 0.05-0.01). Significant correlation was present between obesity and 5 factors, named sex,body mass index of father, eating velocity, midnight snack and indulgence in or being choosy food (P ＜ 0.05-0.01).CONCLUSION: It is discovered in the investigation that the morbidity of malnutrition and obesity in middle-school students are very high and that is all closely related to sex and indulgence in or being choosy food. In order to correct malnutrition and obesity in middle-school students, it is necessary to provide correct nutritional knowledge and help them arranging diet rationally and establishing healthy life pattern.

Objective To evaluate the clinical efficacy and toxicities of radical intensity-modulated radiotherapy (IMRT) combined with reduction in dose of prophylactic irradiation in the treatment of stage Ⅲ small cell lung cancer (SCLC).Methods A retrospective analysis was performed on the clinical data of 40 patients with stage Ⅲ SCLC who were admitted from January 2010 to August 2012.The prescribed dose was 60 Gy in 30 fractions to the primary gross tumor volume and was 54 Gy in 30 fractions to the planning target volume.All patients received induction chemotherapy,31 patients received adjuvant chemotherapy,and 22 patients received concurrent chemoradiotherapy;the platinum-based chemotherapy combined with etoposide or teniposide was adopted.Prophylactic cranial irradiation (25 Gy in 10 fractions) was administered to 17 patients.The short-term tumor response was evaluated by RECIST 1.0,and radiation-related toxicities were assessed by CTCAE 4.0.Overall survival (OS),local recurrence-free survival (LRFS),and progression-free survival (PFS) were calculated by Kaplan-Meier method.Results The short-term tumor response rate was 98％.The follow-up rate was 100％.Twenty-two patients were followed up for at least 2 years.The 1-and 2-year OS rates were 84％ and 48％,respectively; the LRFS rates were 89％ and 85％,respectively; the PFS rates were 61％ and 41％,respectively.Grade 0-1 radiation-related pneumonia was observed in 65％(26/40) of all patients,grade 2 in 25％ (10/40),grade 3 in 5％ (2/40),and grade 5 in 5％ (2/40).Grade 0-1 radiation-related esophagitis was observed in 53％ (21/40) of all patients,grade 2 in 43％ (17/40),and grade 3 in 5 ％ (2/40).Conclusions Preliminary results from this study suggested that IMRT combined with reduction in dose of prophylactic irradiation is safe and effective in patients with stage Ⅲ SCLC and is worth further evaluation in a large,prospective,randomized study.

Based on avian leukosis virus ( ALV) p19 gene terminal nucleotide sequence, a 82 bp double-stranded DNA fragment was chemically synthesized and cloned into the expression vector pGEMEX-1. The sequencing result indicated th at the cloned fragment was a correct version of the one designed both in nucleot ide sequence and in its open reading frame. The recombinant was used to transfor m E.coli BL21 (DE3). The cloned fragment was expressed as a fused protein wi th T7 gene 10 leader peptide and was shown to be 34 kD in size on SDS-PAGE gel when induced with 1 mmol/L IPTG. The expression product was able to bind immunol ogically to rabbit anti-ALV serum in Western-blot assay and is being tested to differentiate exogenous from endogenous ALV.
