OBJECTIVETo investigate the prevalences of overweight and obesity in the rural communities in Hanzhong, Shaanxi Province.

METHODSA total of 3030 residents in the rural areas of Hanzhong city were selected by stratified random sampling method to take questionnaire-based survey and physical examinations.

RESULTSThe data of 3017 valid subjects (1048 men and 1969 women) entered the final analysis. The average body mass index was (22.9±4.2) kg/m(2) [(23.0±5.5) kg/m(2) in men and (22.9±3.2) kg/m(2) in women]. The prevalence rates of overweight and obesity were 27.9% and 5.9% respectively, and the standardized rates were 23.4% and 5.4%, respectively. More specifically, prevalence rates of overweight and obesity were 28.3% and 6.1% in men (standardized rates were 24.7% and 7.5%, respectively) and 27.6% and 5.8% (standardized rate were 22.8% and 4.5% respectively) in women. The overweight/obesity was more often in young and mid-aged married men with higher education and socioeconomic status and in middle-aged and older women with less education from wealthier households.

CONCLUSIONThe prevalences of overweight and obesity are relatively high in the rural areas of Hanzhong, and therefore effective interventions are warranted.

BACKGROUNDAt present, China has listed the compound tablet containing a fixed dose of rosiglitazone and metformin, Avandamet, which may improve patient compliance. The aim of this study was to evaluate the efficacy and safety of Avandamet or uptitrated metformin treatment in patients with type 2 diabetes inadequately controlled with metformin alone.

METHODSThis study was a 48-week, multicenter, randomized, open-labeled, active-controlled trial. Patients with inadequate glycaemic control (glycated hemoglobin [HbA1c] 7.5-9.5%) receiving a stable dose of metformin (≥1500 mg) were recruited from 21 centers in China (from 19 November, 2009 to 15 March, 2011). The primary objective was to compare the proportion of patients who reached the target of HbA1c ≤7% between Avandamet and metformin treatment.

RESULTSAt week 48, 83.33% of patients reached the target of HbA1c ≤7% in Avandamet treatment and 70.00% in uptitrated metformin treatment, with significantly difference between groups. The target of HbA1c ≤6.5% was reached in 66.03% of patients in Avandamet treatment and 46.88% in uptitrated metformin treatment. The target of fasting plasma glucose (FPG) ≤6.1 mmol/L was reached in 26.97% of patients in Avandamet treatment and 19.33% in uptitrated metformin treatment. The target of FPG ≤7.0 mmol/L was reached in 63.16% of patients in Avandamet treatment and 43.33% in uptitrated metformin treatment. Fasting insulin decreased 3.24 ± 0.98 μU/ml from baseline in Avandamet treatment and 0.72 ± 1.10 μU/ml in uptitrated metformin treatment. Overall adverse event (AE) rates and serious AE rates were similar between groups. Hypoglycaemia occurred rarely in both groups.

CONCLUSIONSCompared with uptitrated metformin, Avandamet treatment provided significant improvements in key parameters of glycemic control and was generally well tolerated.

OBJECTIVETo explore efficacy of imatinib for patients with chronic myeloid leukemia(CML) and its resistance-related factors during the treatment.

METHODSThe clinical data of 214 CML patients received imatinib were analyzed respectively in our hospital from April 2005 to December 2010. The therapy history and efficacy of regular follow-up and factors influencing drug resistance were analyzed. COX regression analysis was used to perform the univariate and multivariate analysis.

RESULTSUntil the end of follow up, thirty-one patients (14.5%) occurred drug resistance. One of them was in accelerated phase(AP), and two in blast phase(BP); 69.2% of patients achieved a complete cytogenetic response(CCyR), and 31.3% of patients achieved a major molecular response(MMR). COX analysis was performed in 207 chronic phase(CP) patients. Univariate analysis showed that the course of disease before treatment, the hemoglobin count, the white blood cell count, whether achieved CCyR or not and whether achieved MMR or not were the influencing factors for imatinib resistance. Multivariate analysis showed that whether achieved CCyR or not was the independent factor for drug resistance.

CONCLUSIONWhether achieved CCyR or not is an independent factor and also a protective factor for imatinib resistance in patients with CML.

This study was aimed to explore whether multiple common gene mutations of leukemia synergistically involved in acute promyelocytic leukemia (APL) pathogenesis, and to investigate their relevance to clinical features, cytogenetics and molecular risk stratification. 84 specimens of admitted de novo APL patients from February 2005 to October 2010 were collected, the gene mutations of bone marrow mononuclear cells and clinical features of mutation-positive patients were analyzed by genomic DNA-PCR. The results indicated that the prevalence of mutations was 60.7% (51/84), in which the mutations with the highest incidence were found as FLT3-ITD, reaching 27.4% (23/84). Next, there were 12 cases WT1 mutation, 9 for FLT3-TKD, 7 for TET2, 5 for N-RAS, 4 for ASXL1, 2 for EZH2 mutation and 1 positive case in MLL-PTD, IDH1 and CBL mutation respectively. No mutation was found in other JAK1, DNMT3, c-Kit, NPM1, IDH2, RUNX1 and JAK2 (V617F) common leukemia-related genes. Combined analysis with clinical data demonstrated that the patients with FLT3-ITD mutation displayed higher white blood cell counts, while the patients with N-RAS mutation showed lower platelet counts. Overall survival of these patients was obviously shorten as compared with patients with wild-type. This difference between mutant and wild-type of all above mentioned cases was statistically significant (P < 0.05). The difference between APL with simple t (15;17) and additional abnormal karyotype was not statistically significant. It is concluded that the FLT3-ITD mutation is recurrent genetic change in APL, and together with N-RAS mutation indicates poor prognosis. Additional abnormal karyotype does not associate with prognosis of APL.

Objectivc To examine the relationship between cigarette smoking and body mass index(BMI) as well as waist circumfcrcnce (WC) of men from 9 rural districts ofHanzhong,Shaanxi province.Methods Cross-sectional data was analyzed from Hanzhong Health Survey on rural residents in 2010.Quantile regression mode was used to compare the results using the BMI (WC) and smoking slatus (degree) as the dependent variables and independent variable and confounding factors were also controlled.Results 1039 rmale residents of rural areas of Hanzhong city were investigated.The prevalence rates on overweight and obesity among the males were 28.0％ and 5.9％,with central obesity as 35.0％ and the rate of currcnt cigarette smoking was 63.6％ in the areas.Results from the quantile regression showed that the relationship between smoking status and BMI beyond 80 percentile in men (BMI=24.4) which was not significantly different BMI among the heavy smokers,was much higher than those mild smokers beyond 90 percentile (BMI=24.9).WC of the current smokers was significantly higher than those ex-smokers beyond the 95 percentile (WC=96.7 cm).WCs of the moderate and heavy smokers had an increase along with the increase of WCs beyond the 85 percentiles (WC=89.9 cm).Conclusion The effect of smoking status and BMI (WC) were inconsistent,however,with BMI and WC increased among the subjects whose BMI or WC were at the high extreme end of the distribution.Thus,we should advise the obese subjects to quit smoking.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.
