OBJECTIVE To improve the professional ability of nosocomial infection managers.METHODS By analyzing the status quo and questions among nosocomial infection managers,we explored the essentiality of professionalism construction of the team of nosocomial infection managers and brought forward a way for it.RESULTS It is necessary to set up a professional education and culture system,improve the related guarantee system and keep the team of nosocomial infection managers in stabilization for strengthening the professionalism construction of the team.CONCLUSIONS It is the objective requirement to promote the construction and development of nosocomial infection discipline that impels professionalism construction of the team of nosocomial infection managers.

OBJECTIVE To investigate the function of department of nosocomial infection management in practice.METHODS It was analyzed the situation that the functional management of department of nosocomial infection in China could not be fully used at present.As far as the main content of nosocomial infection control was concerned,it brought forward the idea of performing the functional management of department of nosocomial infection in practice.RESULTS According to establishing the function of department of nosocomial infection management,strengthening the professional ability,and improving the service,both the effect and quality of nosocomial infection management could be enhanced.CONCLUSIONS The same as medical treatment,scientific research,nursing and logistic management,nosocomial infection management should stick to the legal management,and then its function can be effectively used.

Objective:To determine the effectiveness and validity of morphometric analysis made from dental panoramic tomograms(DPTs) for predicting mandibular bone mineral density(BMD) while taking the result of dual energy X-ray absorptiometry(DXA) as gold standard.Methods: Twenty healthy subjects(8 male,12 female) with intact dentition,aged from 1126 years old,were included in the present study.The BMD of each patient was measured at the lumbar spine(L1-L4) by DXA;the results were obtained based on the density of surface(g/cm2).Dental panoramic radiography was carried out using dental panoramic tomography(RTG230/ENR,made in Italy).Mandibular cortical thickness(MCT) and panoramic mandibular index(PMI) values were calculated and their relationship with DXA measurements were subjected to correlation analysis.The validity of MCT and PMI measurements were assessed by sensitivity and specificity.Results: We found mandibular BMD was positively correlated with MCT(r=0.268,P

Objective To investigate the relationship between serum uric acid level and body fat depots as well as the possible influencing factors of the relationship in type 2 diabetic patients.Methods Five hundred and thirty two patients hospitalized for type 2 diabetes were recruited in this study.According to serum uric acid,the subjects were classified into normal uric acid group (group NUA,n =426) and high uric acid group ( group HUA,n =106 ).Anthropometry ( BMI,waist circumference,hip circumference and WHR),serum uric acid level,blood glucose,renal function and lipid levels were compared between the two groups.Results Serum uric acid level was closely related to body fat distribution:(1) in group HUA,WHR,BMI,BUN,SCr and TG were significantly higher than that of group NUA ( [ 0.94 ± 0.07 ] vs.[ 0.91 ± 0.07 ],[ 26.91 ± 3.90 ]kg/m2 vs.[23.84 ±3.80] kg/m2,[8.66 ±5.94] mmol/L vs.[6.29 ±3.64] mmol/L,[93.9 ± 67.6 ] μmol/Lvs.[63.9 ± 20.6 ] μmol/L,[ 2.65 ± 1.92 ] mmol/L vs.[ 1.86 ± 1.46 ] mmol/L,respectively; all P ＜ 0.05 ] ;while HDL-C was lower in Group HUA than in group NUA ( [ 1.09 ± 0.32 ] mmol/L vs.[ 1.24 ± 0.45 ] mmol/L,P ＜0.05).(2) Multiple regression analysis revealed that the serum uric acid levels were positively correlated with BMI,SCr,and TG ( b =0.201,0.500,0.153,respectively,P ＜ 0.05 ),but negatively correlated with HbA(1)c and HDL-C ( b =- 0.168 and - 0.121,P ＜ 0.05 ).Conclusion In patients with type 2 diabetes,serum uric acid levels are closely related with the BMI and Glucose/lipid metabolism,which suggests that body weight control is as important as the uric acid lowering treatment in patients with type 2 diabetes to cut the risks of cardiac and vascular diseases.

OBJECTIVETo invesitigate the clinical effects of percutaneous closed reduction and cannulated screw internal fixation combined with external fixation in the treatment of unstable pelvic fractures.

METHODSFrom April 2006 to May 2009,29 patients with pelvic fractures of rotatory instability were treated with closed reduction and screw internal fixation combined with external fixation. There were 19 males and 10 females with an average age of 31 years old (ranged from 19 to 53 years). Based on the Tile classification,17 cases were type CI and 12 case were type C2. Tornetta standard and Majeed score were used to evaluated the clinical effect after operation.

RESULTSAll patients were followed up from 10 to 24 months with an average of 16 months. There were no nerve injuries and other organ injuries, only one case of infection was found and it was cured with wound dressing. Time of fracture union was from 14 to 18 weeks with the mean of 16.2 weeks. No loosening, slippage or breakage of the screw were found. According to the Tornetta standards,14 cases obtained excellent results, 10 good, 4 fair and 1 poor. The Majeed score was 87.2 ± 11.3, 16 cases got excellent results, 9 good and 4 fair.

CONCLUSIONClosed reduction and screw internal fixation combined with external fixation is an effective way to treat unstable pelvic fractures with Tile type C1 and Tile type C2.

Background Streptozotocin (STZ)-induced type 1 diabetic model is an acceptable model and is often used to the study of diabetic retinopathy (DR).However,the model is often established using retinal digest preparation in vitro in albino rats,and therefore it is difficult to evaluate the change of retinal vessels by fundus fluorescein angiography (FFA) in vivo.Recently,pigmented rats are being used as the DR model.But the study on the comparison between albino rat model and pigmented rat model is seldom.Objective This study was to observe and compare the manifestations of FFA and retinal digest preparation in early diabetic pigmented diabetic rat and albino diabetic rat,and to select the right model of DR using FFA.Methods Type 1 diabetic models were induced in 15 six-week-old health male BN rats and 15 six-week-old health male SD rats by the injection of STZ (55 mg/kg) via tail vein.The models were thought to be successful in the rats with the blood glucose level ≥ 16.7 mmol/L.The right eyes of the rats were extracted 6 weeks after injection of STZ.Lens were examined by slit lamp microscope.Retinal vascular changes were examined by fundus photography,FFA and periodic acid Schiff staining of retinal digest preparation.The manifestations of FFA and retinal digest preparation were contrasted between BN rats and SD rats.The number of eyes with lens opacification was compared by Chi-square test and the ratio of vascular endothelial cells and perithelial cells (E/P) was compared between BN rats and SD rats.The use and care of experimental animals complied the Statement of Ethic Committee of Tianjin Medicine University.Results Six weeks after injection of STZ,11 BN rats and 10SD rats were included in this study.The blood levels were (24.73±2.98) mmol/L and (22.36±3.65) mmol/L in BN rats and SD rats,respectively,without significant difference between the 2 types of rats (t =7.873,P＞0.05).Lens opacification occurred in 6 BN rats and in 5 SD rats (P=0.717).FFA showed the clear retinal vascular under the brown background.Evident vessel disorder and fluorescence leakage like background stage of DR were seen in 9 eyes.However,in the SD rats,retinal vessel abnormality could not exhibited owing to the interference of choroid fluorescent light from choroidal vessels and vortex vein.Retinal digest preparation exhibited that unevenness of vessel diameter,decrease of perithelial cells and increase of endothelial cells in both types of rats.The E/P values were 11.50±3.68in the BN rats and 12.86±3.94 in the SD rats,without significant difference between them (t=9.785,P＞0.05).Conclusions The abnormality of fundus vascular morphology can be better displayed in pigmented diabetic rats than albino rats by FFA in vivo.
