Objective To develop a diabetes risk score (DRS)to predict the risk of development of incident diabetes in male senile people in Beijing. Methods DRS was developed basing on a test group including a cohort of 1 370 individuals aged 48-87 years without diabetes at baseline, followed for 10 years by Logistic regression and validated on a value group including a cohort of 340 individuals aged 43-88 years without diabetes at baseline. Results The model with the highest area under the ROC curve ( AUC ) included age, hypertension,history of hyperglycemia, body mass index, fasting plasma glucose, triglycerides, and high-density lipoproteincholesterol (HDL-C). DRS was developed basing on this model with a range from 0 to 12 and an optimal cut-off of 4. AUC were respectively 0. 726 ( 95% CI0. 692-0. 759 ) and 0. 765 ( 95% CI0. 691-0. 839 ) in test group and validation group. The sum score value ≥4 had sensitivity of 65.3% and 68. 1%, specificity of 70. 0% and 64.8%, positive predictive value of 37.0% and 23.2%, negative predictive value of 88.2% and 94. 1%.Conclusion The DRS, derived from clinical information combined with plasma glucose and lipids, is an effective tool to predict incident diabetes.

Objective To find out the prevalence of periodontitis in a petrochemical industry community in Ningbo ; to identify the possible factors of the prevalence; to evaluate the impact of the polluted environment on the oral health of the employees;and to provide information to the enterprises in oral diseases prevention.Methods 2 108 peoples who received regular physical examination in a petrochemical industry community in Ningbo was included.To each subject,a periodontal examination according to the principles and fundamental methods which were used in the third national oral health epidemical survey was carried out,the fast blood was phlebotomized,total cholesterol(TC),triglyceride (TG),uric acid,blood glucose and other serum indexes levels were recorded.These subjects were stratified into two age groups.Data was analyzed with x2 test and multiple regression.Results In the group of 2 108 selected subjects,the periodontitis rate was 52.3 ％ [95 ％ CI:(52.3 ± 2.1) ％].In the multivariable logistic regression model,the old-age groap age(OR =4.783,P =0.000),blood pressure (OR =1.526,P =0.001) and blood glucose (OR =1.560,P =0.045) were the risk factors of periodontitis,while the environmental factor(OR =0.661) was excluded.In the young and middle-age group,blood pressure (OR =2.184,P =0.000),blood glucose (OR =2.314,P =0.001),TC(OR =1.356,P =0.003),and alcohol (OR =1.382,P =0.02) were the risk factors of periodontitis.Conclusion The levels of blood glucose,TC,blood pressure and alcohol should be considered in periodontitis prevention and the sulfureted hydrogen-based environment factor had no adverse impact on periodontitis.

Objective To investigate the effects of elasticity resistance (Ers) in respiratory system on oxygenation in patients with acute lung injury (ALI) after recruitment maneuvers (RM). Method Meta-analysis of data about the effects of recruitment maneuvers on oxygenation in ALI patients with different elasticity resistances in respiratory system carried out with pooling of study-oriented data stored in Pubmed, Embase, Web of Science databases from January 1999 to June 2010. Results A total of 281 articles were taken, and 20 of them included a sample size of 395 ALI patients. In patients treated with RM in different degrees of respiratory system elasticity resistance ( ≥33.3 cmH2O/L and ＜33.3 cmH2O/L), the effect of RM was better in patients with the high respiratory system elasticity resistance than that with the low one [(51.97 + 8.89) mmHg vs. (35.13 ± 10.33 ) mmHg], P ＜ 0. 01 ), but the high respiratory system elasticity resistance was potentially to lower blood pressure [(4. 33 ± 1.32 ) mmHg vs. (0.22 ± 1.03 ) mmHg],P ＜ 0.01 ). Conclusions This study suggests RM could improve oxygenation of ALI patients with high respiratory system elasticity resistance, and caution must be made to avoid hypotension during RM.

Objective To compare the efficacy and safety of intravenous thrombolysis on cardiogenic cerebral infarction and noncardiac infarction by recombinant tissue plasminogen activator (rt-PA). Methods Comparations of NIHSS, mRS and adverse events before and after treatment were made between the cardiogenic group and the noncardiac group. Results No significant differences in the NIHSS and mRS were found between the two groups. The incidence of brain hernia and dermatorrhagia in the cardiogenic group was higher than that in the noncardiac group. Conclusion Rt-PA therapy in cardiogenic cerebral infarction was effective and safe in spite of higher incidence of hemorrhage and brain hernia.

·AIM: To analyze the postoperative anatomical and functional outcomes as well as complications after combined phacoemulsification, pars plana vitrectomy (PPV), removal of the intraocular foreign body (IOFB) and intraocular lens (IOL) implantation in patients with traumatic cataract and intraocular foreign body.·METHODS: Medical records of 13 patients (13 eyes)with traumatic cataract and IOFB who had undergone combined phacoemulsification, PPV, foreign body extraction and IOL implantation were retrospectively analyzed. The postoperative follow-up ranged from 2 to 12 months. The main measurements of outcomes were the extraction success of cataract and intraocular foreign body, intraoperative and postoperative complications and the final best corrected visual acuity (BCVA).·RESULTS: The mean age of 13 patients (10 male, 3 female ) was 36.8 years (range: 17-65 years). All eight lOFBs were removed. Four intraocular lenses were implanted after vitrectomy intraoperatively. In 5 cases, intraocular lenses were implanted during the second operation. Intraocular lenses were not implanted in 4 cases. BCVA at last ranged from 0.8 to hand movement. BCVA was 0. 5 or better in four eyes, 0.1 to 0. 4 in five eyes, less than 0.1 in four eyes. Intraoperative complications were encountered in 3 patients. They had vitreous hemorrhage. Postoperative complications were encountered in 2 patients. They had retinal detachment. The reoperations of the two patients were successful.·CONCLUSION; The combined phacoemulsification,PPV, removal of IOFB and IOL implantation is safe and effective for patients with traumatic cataract and intraocular foreign body. The visual outcome depended primarily on the corneal or scleral wound and underlying posterior segment pathology and sites.

Objective To compare curative effect of decompression and conservative treatment for traumatic superior orbital fissure syndrome to discuss the operation indications and the operative oppor-tunity for this syndrome. Methods Data of 12 patients (seven males and five females) with 14 sides were compared to evaluate different curative effect between decompression and conservative treatment so as to optimize the initial corresponding treatment. Results The patients were at mean age of 28 years and followed up for mean six months. All patients were complicated by one and more of following symptoms in-cluding ophthalmoplegia, ptosis, proptosis and anaesthesia in the distribution of V1 and a fixed dilated pupil. There was one patient complicated by orbital apex syndrome. CT showed involvement of the superi-or orbital fissure in seven patients. Of seven patients treated with decompression, six got recovery at dif-ferent degrees. Meanwhile, three out of five patients treated with conservative treatment recovered to some extent. Conclusions Early effective treatment can improve the functional rehabilitation of the injured nerve. Decompression of superior orbital fissure is proved to be effective in ameliorating symptome, re-ducing disability and improving quality of life.

Objective To discuss clinical effects of early (<48 hours after injury) fraeture exter-nal fixation in treatment of severe traumatic brain injury (TBI) combined with extremity fracture. Meth-ods The study involved patients with no statistical difference in aspects of age, sex, GCS, fracture ,distri-bution and general condition. According to different treatment methods at early stage (<48 hours), the pa-tients with TBI were divided into Group A (early extremity fracture external fixation) and Group B (early extremity fracture traction or cast immobilization). A comparative observation was done on complications in-cluding bedsore, pneumonia and deep venous thrombosis and on duration in ICU, hospitalization, time for fracture healing and mortality in two groups. Results Incidence rate of bedsore, pneumonia, deep ve-nous thrombosis and mortality in Group A was lower than that in Group B (P<0.05), and Group A had shorter time for ICU, hospitalization and fracture healing (P < 0.05). Conclusion For patients with se-vere TBI combined with extremity fracture, early fracture external fixation is more effective to reduce com-plications, shorten the recovery time and reduce mortality, compared with conservative methods.
