BACKGROUND: Diabetes mellitus is a chronic metabolic disease caused by various factors,such as environmental factor,inherited factor,etc.,and its cause isn't very clear now. This study aims to investigate the risk factors mentioned above in the onset of diabetes mellitus, and is of significance in the first and second grade of prevention of diabetes mellitus.OBJECTIVE: To investigate the risk factors of type 2 diabetes mellitus to provide evidence for the proper intervention of it.DESIGN: Cross-sectional study based on diagnosis.SETTING: Department of epidemiology in a university and department of endocrinology in a university hospital.PARTICIPANTS: The subjects were residents who have resided in town and country of Dalian for more than 5 years and were elder than 40 years old. The method of stratified cluster random sampling was carried out among natural persons who were divided into two groups according to city and country. Totally 2 500 persons were taken in total and 1 250 persons were from each group. The subjects who had been diagnosed as diabetes mellitus were included.METHODS: Questionnaire survey was employed for all the subjects, including physical examinations such as height,weight,waist girth,hip girth,blood pressure,blood glucose,etc. Patients of type 2 diabetes mellitus were taken as the case group and the normal was as the control group. The unconditional univariate and multivariate logistic regression were used.MAIN OUTCOME MEASURES: Unconditional logistic regression analysis of risk factors of type 2 diabetes mellitus with single factor analysis and multivariate analysis.RESULTS: Family history of diabetes mellitus(OR = 2.339),obesity[body mass index(BMI),OR = 1.462],systolic pressure(OR = 1.016),hyperlipidemia(OR = 1.615), age(OR = 1.043) were the major risk factors for type 2 diabetes mellitus.CONCLUSION: Family history of diabetes mellitus, increase of systolic pressure,obesity,high blood lipid and age are the risk factor for type 2 diabetes mellitus. For all communities,control of body mass and high blood pressure is an important way to prevent type 2 diabetes mellitus.

OBJECTIVETo investigate the correlation between Angle's class III patients' occlusion plane and anterior overbite by controlling the changes in occlusion plane during orthodontic treatment.
METHODSIn total, 90 Angle's class III adult orthodontic patients were selected as the experimental group, and 30 normal adults were selected as the control group. According to the overbite, the class III patients were divided into three groups, and 14 indicators were measured. ANOVA and multiple comparison analysis were used to analyze the difference between class III patients, and linear analysis was used to analyze the correlation between anterior overbite and anterior-posterior occlusion plane.
RESULTSIn class Ill patients, posterior occlusion plane and anterior overbite size were negatively correlated (r = -0.24, P < 0.05), whereas anterior occlusal plane and anterior overbite size were positive correlated (r = 0.23, P < 0.05).
CONCLUSIONThe shape of the occlusion plane varies in different anterior overbite patients. During orthodontic treatment in different overbite class III patients, the vertical height of the posterior teeth and the rotation of the occlusion plane should be controlled.

Objective To investigate the effects of fluvastatin on the tubulointerstitium damage in progressive diabetic kidney disease. Methods A rat model of type 2 diabetic nephropathy (DN) was developed successfully by combination of dietary induced insulin resistance and low dose STZ induced hyperglycemia after unilateral nephrectomy. Female SD rats were randomly divided into three groups: control rats, type 2 diabetic rats and type 2 diabetic rats treated with fluvastatin (2mg/kg/d). After 6 weeks, blood glucose, serum insulin, serum triglyceride and cholesterol, serum creatinine, and urinary protein were measured respectively. The protein expressions of c Jun and tansforming growth factor (TGF) ? 1 were studied by immunohistochemistry. TGF ? 1 gene expression was studied with a RT PCR technique. Results Fluvastatin at lower doses, which did not influence blood glucose and blood lipid level, significantly inhibited expression of c Jun protein(0 2536?0 0180 vs 0 5855?0 0314, P

OBJECTIVETo investigate the relationship between tongue presentations and the serum level of C-reactive protein (CRP) in patients with acute cerebral infarction (ACI).
METHODSTongue presentations of 200 incipient unilateral ACI patients were observed, their serum CRP level was determined, and the relationship between the two entries was analyzed.
RESULTSSerum level of CRP in patients with thick tongue coating were significantly more than those with thin coating (117 cases vs. 73 cases); tongue coating was greasy in 149 patients and un-greasy in 51 patients. Spearman correlation analysis showed that the serum level of CRP was positively correlated with the thickness of tongue coating (r = 0.186, P = 0.008); also with the greasy degree. The difference of CRP levels in patients with different color and dryness of tongue was insignificant statistically (P > 0.05).
CONCLUSIONCorrelation between tongue presentations and serum CRP level is possibly existed in patients with ACI.

Objective To analyze the genetic model of attention deficit hyperactivity disorder(ADHD).Methods The segregation analysis and polygenic multiple threshold model were used to prove the polygenic model and to estimate the heritability and recurrence risk of ADHD in each degree relatives.Results 1. The average heritability of ADHD was (102.47?9.78)%;2.The first-degree relatives of probands were in high risk for ADHD(23.0%)compared with colony prevalence rate(2.6%). The ADHD prevalence of each degree relatives rapidly decreased with the increased magnitude of consanguineous relationship of each degree relatives and ADHD probands. Conclusions The genetic model of ADHD is the most likely polygenic inheritance with major genes, which suggested that the genetic factor might play an important role in the liability variance of ADHD.Apart from the involvement of multiple genes,each gene contributes a small additive effect,and the major genes may be involved as well.

Objective To evaluate the efficacy of integrated traditional Chinese medicine(TCM)and western medicine in treatment of acute exacerbations of chronic obstructive pulmonary disease(AECOPD)combined with respiratory failure,TCM syndromes of spleen-kidney-yang deficiency and phlegm-dampness by comparison between the integrated therapy and simple western therapy in treatment of the disease. Methods 160 patients with AECOPD combined with respiratory failure,spleen-kidney-yang deficiency and phlegm-dampness syndrome in the intensive care units(ICU)of Affiliated Hospital of Chengdu University of TCM and other four hospitals were randomly allocated into two groups in this double-blinded,multicenter,prospective,randomized,controlled trial. In the control group (78 cases),western medicine and placebo were given to the patients,and in the treatment group(82 cases), conventional western medicine plus fei-shuai mistura 25 mL were administered,four times per day,the therapeutic course lasting for 2 weeks in both groups. The all-cause mortality,respiratory failure-cause mortality,improvement of modified Medical Research Council(mMRC)Dyspnea Scale grades,6 minutes walk distance(6MWD),the forced expiratory volume in 1 second/forced vital capacity(FEV1/FVC)were observed in the 28 days after the end of treatment. Results In the comparisons between the control and treatment groups,there were no statistical significant differences in the all-cause mortality〔54.87%(45/82)vs. 64.10%(50/78)〕and the cases of FEV1/FVC(both P>0.05)in the 28 days after the end of treatment;the 28 day respiratory failure-cause mortality was significantly decreased〔19.51%(16/82)vs. 33.33%(26/78),P<0.05〕,the number of patients with mMRC Dyspnea Scale grades (1-2)was obviously increased(22 cases vs. 7 cases,P<0.05),and the number of patients with 6 MWD grades (4-6)was markedly enhanced in the treatment group(21 cases vs. 8 cases,P<0.05). Conclusions The integrated TCM and western medicine has better therapeutic results in improvement of the patients' degree of dyspnea, 6 MWD and respiratory failure mortality than simple treatment with western therapy for treatment of patients with AECOPD combined with respiratory failure, spleen-kidney-yang deficiency and phlegm-dampness syndrome. However,in regard to the effect on pulmonary function and all cause mortality,the integrated therapy for treatment of such patients in short term has no significant effect.
