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 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 AMI is a prevalent global health condition.This study assessed the effects of PLGF and VEGF in a rat model of post-AMI.Methods Wistar rats underwent LAD ligation and injection of VEGF,PLGF,VEGF + PLGF,antiVEGFR1,anti-VEGFR2,anti-VEGFR1 + anti-VEGFR2,IgG2α,or saline,into the infarct border zone.We also set up a pseudo-operation group.Two weeks later,heart function was detected by hemodynamic and geometry,then the hearts were dis sected and HE stained.We assessed vW factor and α-SMA by immunohistochemistry and cardiomyocyte apoptosis rate by TUNEL.Results Rats in the VEGF + PLGF group performed significantly well in cardiac function,had weaker LV remodeling and less cardiomyocyte apoptosis.There were no obvious changes in VEGF group.The use of VEGFR1/VEGFR2 antibody didnt deteriorate the rat's cardiac function.More new-born arteries were seen in PLGF and VEGF + PLGF rats,and change wasnt found in other groups.Lastly,the most angiogenesis,the least left ventricular remodeling and the best heart function were observed in VEGF + PLGF group.Conclusion Earlier intervention with PLGF or VEGF + PLGF can improve heart function in rats with AMI; VEGF alone didnt improve heart function.VEGFR1/VEGFR2 antibody didnt aggravate the rat's heart function.This indicates that left ventricular and coronary remodeling may involve other factors.

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 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.

Objective This study was to systemically evaluate the efficacy of TACE before hepatectomy on resectable primary HCC.Methods The articles focused on preoperative TACE for resectable primary HCC,published from Jan.1,1980 to Jan.1,2008,were selected by computerized search of literatures and manual search of bibliographies.The clinical controlled trials meeting inclusion criteria were reviewed systematically by meta-analysis.The reported data were processed with the statistical techniques of meta analysis.The combinability of the studies was assessed in terms of clinical and statistical criteria.Tumor-free survival rate was calculated.And pooled estimates were computed according to a fixed or random effect model by heterogeneity.Results A total of 1288 patients were included in 8 trials.There was no difference between the two groups in the 1,3-year tumor-free survival rate.Conclusion Preoperative TACE for resectable primary hepatic carcinoma can't improve survival rate.

Objective To observe the all-cause and cardiocerebrovascular disease(CCVD)-related mortalities in the senile male population and the relationship of them with fasting plasma glucose (FPG) level.Methods A survey was performed among 1 572 male subjects aged 60-90.All the subjects were groups were calculated by Kaplan-Meier method and the log-rank test was used to compare the survival rates of the 4 groups.Logistic regression model was used to analyze the correlation factors of all-cause mortality and CCVD-related regression model analysis showed that age was related with the all-cause mortality.Among all these factors, age, body mass index, FPG and the history of CCVD had the relationships with the mortality of CCVD.Conclusion In the older male population, CCVD are considered as one of the main causes of death.With the increased levels of FPG, the all-cause mortality and CCVD mortality of senile male population are increased.

In order to improve the sharing of DICOM, a proposal is offered to introduce XML into DICOM on the SPIE 2005 and in this way, better readability and expansibility of DICOM files have been achieved. On this basis, the DICOM data structure is improved further by replacing the one-dimension linear data structure with multilayer tree-shaped data structure. And thus the nesting and dependence relationships between information object and data elements are much clearer and it is more convenient and easy to browse DICOM image files.
