RÉSUMÉ

[Summary] During recent years, increasing evidences have indicated that type 2 diabetes mellitus(T2DM) might increase the risk of certain tumors; the process might be not only related with the chronic pathologic status of T2DM such as hyperglycemia, hyperinsulinemia, insulin resistance, dyslipidemia, status of chronic inflammation but also associated with the long-term use of anti-diabetic drugs (i. e. sulfonylureas, biguanides, glitazones, dipeptidyl peptidase-4 inhibitors, glucagon-like peptitide-1 receptor agonists), as well as the use of insulin and insulin analogues. Herewith a system review was made about the recent progress in studying T2DM and tumor risk.

RÉSUMÉ

Multilevel models are applicable to both the quantitative data and categorical variables. We used the methods, including the multilevel models, analysis of covariance and CMH chi-square test, to analyse different types of data, to explore the application of multilevel models in the analysis of the multicenter clinical trial center effect. The results showed that the analysis of covariance is more sensitive to find the center effect for quantitative data, while multilevel models are more sensitive to categorical variables. It can be seen that results with different analytical methods for center effect are not the same, and the most appropriate method should be selected in accordance with the characteristics of data, the objective of research, and the applicable conditions of the various methods in practical use.

RÉSUMÉ

OBJECTIVES: The Tinnitus Handicap Inventory (THI) is a commonly used self-reporting tinnitus questionnaire. We undertook this study to determine the reliability and validity of the Chinese-Mandarin version of the Tinnitus Handicap Inventory (THI-CM) for measuring tinnitus-related handicaps. METHODS: We tested the test-retest reliability, internal reliability, and construct validity of the THI-CM. Two-hundred patients seeking treatment for primary or secondary tinnitus in Southwest China were asked to complete THI-CM prior to clinical evaluation. Patients were evaluated by a clinician using standard methods, and 40 patients were asked to complete THI-CM a second time 14+/-3 days after the initial interview. RESULTS: The test-retest reliability of THI-CM was high (Pearson correlation, 0.98), as was the internal reliability (Cronbach's alpha, 0.93). Factor analysis indicated that THI-CM has a unifactorial structure. CONCLUSION: The THI-CM version is reliable. The total score in THI-CM can be used to measure tinnitus-related handicaps in Mandarin-speaking populations.

RÉSUMÉ

Objective To prepare targeted micorbubble with low immunogenicity. Methods The microbubbles were produced with different phospholipids and identified by the fluorescent method. Detect the level of C3a after reaction with human serum in vitro with enzyme-linked immunosorboent assay (ELISA) method and the number of microbubble binding with the streptavidin packed on the dish by using the parallel plate flow chamber. Results The level of C3a was (1.037±0.047)ng/ml in MBb group,(1. 326 ± 0. 042)ng/ml in MBe group and ( 1.004 ± 0.031 ) ng/ml in MBc group. The level of C3a in MBb group was significantly lower than that in MBe group( P <0.05),and there was no significantly difference between MBb group and MBc group ( P > 0. 05). The parallel plate flow experiments showed that the number of MBb(15.2 ± 11.3) in each field of view binding with the streptavidin packed on the dish was significantly fewer than that of MBe ( 103.2 ± 28.3) ( P<0.05 ), and there was no significantly difference between MBb and MBc(17.8 ± 11.9) ( P >0.05). Conclusions The targeted microbubble with low immunogenicity has been prepared successfully,which can be used for further experiment in vivo.

RÉSUMÉ

Objective To compare the safety and effectiveness between treatments with autologous platelet gel (APG) versus standard care for treating refractory diabetic dermal ulcers.Methods The 46 patients with proved nonhealing diabetic dermal ulcers were enrolled. Eligible for the study were patients with grade II/III ulcers according to Wagner, lasting for at least 2 weeks and with no signs of infection at recruitment.Patients were given their informed consent document and randomly assigned to two groups: standard care (ST, n=23) or standard care plus topic application of APG (APG, n=23) for twelve weeks.The treatment of blood glucose, blood pressure and lipids was optimized and the empiric antibiotic treatment was further adjusted according to the results of culture and sensitivity testing in all patients. APG treatment consisted of wound dressing with APG, followed by topical washing and cleaning. The APG was then covered with vaseline gauze for 72 hours, after which the ulcers were treated by standard care. Participants were seen thrice a week, twice a week, or at weekly intervals. Twelve weeks observation was set as the end point.Results The would of APG group were improved in 22 patients with ulcers healed completely and 1 case with would area reduced. In the ST group, 13 ulcers were healed, 6 worsened and 4 with would area reduced. The cumulative rate of ulcer healing was 95.7% in the APG group versus 56.5% in the ST group (P=0.002). The total effective rate in APG vs ST group was 100.0% vs 73.9% (P=0.009). By Kaplan-Meier analysis,the time-to-healing of ulcer and time-to-lutation of sinus were significantly different between two groups (log-rank, P=0.006, 0.000, respectively). No treatment-related adverse events were observed. Conclusions Treatment with APG in addition to standard care results in a significantly faster and better healing for a refractory diabetic dermal ulcer and does not raise any safety concerns. So APG treatment can be a valuable and effective aid in the management of diabetic foot ulcers.

<p><b>OBJECTIVE</b>To assess the effect of iodised salt for preventing iodine deficiency disorders.</p><p><b>METHOD</b>Cochrane systematic review.</p><p><b>RESULTS</b>Four randomised controlled trials were included. Subgroup analysis performed lay on different ages, interventions and controls. Prevalence of goitre was reduced close to 5% when using distributed iodised salt and market iodised salt plus iodine oil capsule which showed more effective than using market iodised salt alone (OR = 0.10, 95% CI: 0.02 - 0.17). The latter's prevalence of goitre was 14.7%. When using market iodised salt, the iodine urea excretion level showed different results in children group in different countries. Basically, the market iodised salt for preventing iodine deficiency of pregnancy women were effective, but a part of them did not achieve to the ideal status of iodine nutrition.</p><p><b>CONCLUSIONS</b>The needs to be strictly controlled quality of iodised salt and market iodised salt plus iodised oil capsule thus can effectively reduce the prevalence of iodine deficiency disorders. However there was not enough evidence to support that market iodised salt can effectively eliminate these disorders, particularly in children. More eligibility trials are needed for providing more evidences.</p>

RÉSUMÉ

Objective To study the risk factors of pulmonary tuberculosis in Chengdu, Southwest China. Methods A population-based case-control study was used which included 174 cases selected from 12 communities in Chengdu and 174 controls selected from registered population with normal chest radiograph.Cases were active TB patients which were matched for age,sex with controls,then interviewed by trained interviewers using a standardized questionnaire. Results Social economic status measured by education, occupation and income did not show obvions influence to TB; It found that the active smoking, passive smoking,type of cigarettes and alcohol consumption had no significanct effects on TB during logistic regression analysis. The study showed that a person who was smoking and also alcohol intake had a higher risk to get TB (OR=6.12, 95%CI=1.15-32.49). Significant association was showed in the Dose-Response Analysis (OR=1.37, 95%CI=1.30-2.30). Crowded living space (OR=1.14, 95%CI=1.05-1.25), degree of darkness (OR=2.18, 95%CI=1.11-4.27) and moisture (OR=4.06, 95%CI=2.25-7.33), poor sanitary (OR=3.03, 95%CI=1.22-4.44), airpollution of working environment, which were filled with dusts (OR=2.35, 95%CI=1.18-4.70) and chemical fumes (OR=5.15, 95%CI=1.44-18.40) were strongly associated with pulmonary tuberculosis. BMI also had strong relationship with TB (OR=4.72, 95%CI=2.68-8.33). Conclusion Poor environment and exposure to dust and chemical fume under working condition, low BMI, smoking combining alcohol consumption were the risk factors of adult pulmonary tuberculosis in Chengdu, China.
