OBJECTIVE According to the development of nosocomial infection management in China,we design a series of nosocomial infection surveillance and management system,in order to work effectively in real time to control nosocomial infection outbreak,standardly collecting and analyzing the surveillance data of the critical department/area and risk factors for nosocomial infection,so a scientific management for nosocomial infection can be realized.METHODS Adopting C/S framework,the backstage supporter adopted the large-scale database of SQL SERVER 2000 edition,the front application program used PowerBuilder7 programming.The application software where collected all data about nosocomial infection information was integrated into the each work station of the information system,in order to form nosocomial infection surveillance and management network related to any department of the hospital.RESULTS System could come down with the hospital infection case which every hospital department could find to check,put in order,report,count,analyze,have a look around,inquire about,feedback,form the monitoring chart with excellent pictures and texts,and make the better prognosis of the nosocomial infection outbreak.CONCLUSIONS Beijing nosocomial infection surveillance and management system is a medical quality control system of a hospital.This software could afford scientific and standard data for the health care institution and administration to realize the primary information of nosocomial infection and make decisions.

Objective The aim of the study was to observe the change of blood lipid in uremic patients after hemodialysis or peritoneal dialysis. Methods Sera cholesterol(CH), triglyceride(TG), LDL, HDL, ApoA1, ApoB and LP(a) were measured in all patients who were dialystic treated before and after six months.Results CH, TG, LDL, HDL, ApoA1 and ApoB were significant increased in patients with uremia,but HDL, ApoA1 was significant decreased,they were apparent especially after peritoneal dialysis .However,the blood lipid levels of patients with hemodialysis or non-dialysis did not significant difference before or after treatment. Conclusions The metabolism of blood lipid in uremic patients have been changed. The disturbance will aggravate after peritoneal dialysis.We consider that therapy of reducing blood lipid is necessary in the both patients with dialysis and non- diaylsis for the uremic patients.

Objective To compare the accuracy of diagnostic peritoneal lavage (DPL),abdominal computed tomographic(CT) scanning,and abdominal B ultrasound for the diagnosis of blunt abdominal trauma. Methods Prospective study was made on 61 hemodynamically stable abdominal injury patients.The patients received both CT and B ultrasound before DPL ,A laparotomy was done on the condition that one of the three examinations had positive finding.The surgical findings were compared with that of the diagnostic studies. Results The sensitivity,specificity and accuracy were 97.4%,81.7% and 91.8% for DPL; 97.3% 91.3% ,and 95.1% for CT;and 92.3%,90.9% and 91.8% for B ultrasound.Although the sesitivity,specificity,and accuracy of B ultrasound in the diagnosis of blunt abdominal trauma were similar to DPL and CT, B ultrasound had more advantages than DPL and CT. Conclusions B ultrasound can replace DPL.CT as a supplementary method in the diagnosis of blunt abdominal trauma.

OBJECTIVE To study on control measures of surgical site infection.METHODS By forward-looking survey methodology,surgical patients(including obstetrics) with surgical incision infection were investigated.RESULTS The highest infection rate(2.67%) were found in patients with surgical trauma to the largest,longest operation time,coronary artery bypass grafting.In 11 cases surgical site infections,only 1 case were given antibiotics before anesthesia,10 cases were administrated antibiotics post operation more than 4 days.The correct rate of preoperative and postoperative usage of antibiotics was only 9.09%.The size of surgical trauma,operative time,perioperative usage of antibiotics were related to the infection rate.CONCLUSIONS Target monitoing of the surgical site infection can decrease the infection rate.

Objective To analyze the characteristics of hypertension by cross-sectional study of the aged patients with metabolic syndrome (MS). Methods The data, collected from senile population who underwent medical examination in the General Hospital of PLA in 2005, were analyzed retrospectively in order to identify the clinical features of hypertension in aged patients with MS, and the significance of hypertension, as single or one of the components of MS, the prevalence of MS, including the prevalence of MS and its component ailments, prevalence of hypertension in MS population, the constituent ratio of MS and coronary heart disease, and cerebrovascular disease in patients with hypertension. Results The prevalence of MS was 32.19%, in which 8.16% patients were having all the four metabolic abnormalities. Hypertension was the most common metabolic abnormality with a prevalence of 61.78%, which tended to increase with increasing age. The most common combination in MS was abnormalities of blood pressure, glucose and BMI, with a prevalence of 24.67%. Among the population with hypertension, 46.67% of them could be diagnosed as MS, accounting for 89.57% of all MS patients. Patients with MS but without hypertension accounted for only 10.43%. Hypertension complicated with MS or another metabolic disorder showed a high risk of cardiovascular diseases, and the prevalence was 73.52% and 72.69%, respectively. No significant difference was found in the incidence of cerebrovascular disease. The prevalence of abnormal renal function was significantly increased in the group of MS with hypertension, by 1.69 and 1.65 folds of that in the group without MS and the group only with MS and without hypertension. Conclusions There was higher prevalence of MS in the elderly people, and in about 2/3 hypertensive patients it co-existed with one of the components of MS. Hypertension was the most common disorder in MS. Patients with MS and hypertension are having a higher risk of suffering from cardiovascular diseases and abnormal renal function.

Objective To observe the effect of Danhong Injection(DI)on the thyroid hormone level in patients with angina due to coronary heart disease(CHD).Methods Sixty CHD angina patients were equally randomized into the treatment group and the control group.The two groups received routine western medicine such as aspirin,angiotensin convert enzyme inhibitor(ACEI),statins,beta-blockers and nitrate esters,and the treatment group was additionally given intravenous drip transfusion of DI 20 mL,qd.Twenty days constituted one treatment course.After treatment,the therapeutic effect was evaluated and the changes of serum thyroid hormone level were observed.Results In the control group,13 patients were markedly effective,9 effective,8 ineffective,and the total effective rate was 73.3%;in the treatment group,19 patients were markedly effective,6 effective,5 ineffective,and the total effective rate was 83.3%;the difference between the two groups was significant(P

Objective To make sure the effect of dialysate composition on HPMCs.Methods Cell strains were subculturing.There are six groups in this experiment: Group 1(control);group 2(4.25% Glucose);group 3(1.75mmol/L Ca~(2+));group 4(1.25 mmol/L Ca~(2+));group 5(4.25% Glucose+1.75mmol/L Ca~(2+));group 6(4.25% Glucose+1.25mmol/L Ca~(2+)).The capacity of proliferation of HPMCs was assessed by MTT assay. Results Proliferation of HPMCs was inhibited in 4.25% glucose group in time dependence.Ca~(2+) induce proliferation of HPMCs,however,no effect on proliferation of HPMCs exists in different Ca~(2+) group.Conclusion High glucose can inhibit cell proliferation;Ca~(2+)(1.75mmol/L,1.25mmol/L) can promote the proliferation and 1.25mmol/L is better.

OBJECTIVEThis study aimed to evaluate the morphometric changes in the alveolar bone of the maxillary and mandibular anterior regions after retraction in adolescents.

METHODSThe sample size comprised 30 adolescent patients with class 1 bimaxillary protrusion (12 males and 18 females, age: 12-18 years old) and were treated by extracting four first pre-molars. Cone beam computed tomography (CBCT) was performed 1 month before and 1 month after the retraction. For each maxillary and mandibular anterior tooth, the labial and palatal alveolar plates at cervical 1/3, middle 1/3, and apical 1/3 levels for bone thickness changes during the retraction of the maxillary and mandibular anterior regions were checked. The movements of cervical 1/3, middle 1/3, and apical 1/3 levels of the maxillary central incisor were measured. Statistical analyses were performed with SPSS 16.0.

RESULTSFor the adolescents, alveolar bone thickness increased on the labial side and decreased on the palatal side. The alveolar bone thicknesses of cervical 1/3 and middle 1/3 of maxillary central incisor, cervical 1/3 and apical 1/3 of maxillary lateral incisor, middle 1/3 of mandibular central incisor, apical 1/3 of mandibular lateral incisor, and middle 1/3 and apical 1/3 of mandibular canine all increased after retraction. By contrast, the alveolar bone thickness of the apical 1/3 of maxillary canine and the cervical 1/3 of mandibular canine decreased after retraction. No statistically significant difference was observed in other region.

CONCLUSIONDuring retraction, a controlled tipping movement occur in adolescents. After retraction, the alveolar bone thickness of the labial side increase, whereas that of the palatal side decrease. Moreover, the thicknesses of major areas in the alveolar bone significantly increase.
