OBJECTIVE: To provide reference for patients with type I incisions about rational use of antibiotics.METHODS: Between Oct.2007 and Mar.2008,a total of 1 024 medical records of patients with type I incisions from orthopaedics,common surgery,department of gynecology in 12 hospitals of Xining area were sampled for analysis of prophylactic use of antibiotics.RESULTS: 100.0% of the type I incision patients received prophylactic antibiotics;28.4% used antibiotics without indication;16.9% used antibiotics at 0.5～2 h before operation;33.4% used antibiotics at more than 2 h before operation;and 49.7% received antibiotics postoperatively rather than preoperatively.The irrational and nonstandard use of antibiotics manifested as improper in the choice of drug variety,nonstandard in drug combination,irrational in dosage and administration,prolonged use of antibiotics,lacking basis for the change of drug variety etc.CONCLUSION: The prophylactic use of antibiotics in patients with type I incisions from 12 hospitals of Xining area is far from perfect,therefore,it is urgent to strengthen the standard management on the use of antibiotics.

Objective To evaluate the feasibility, safety and effectiveness of interventional occlusion with thin waist occluder for perimembranous ventricular septal defect with pseudoaneurysm. Methods During the period from March 2008 to March 2013 at Shanghai Yodak Cardiothoracic Hospital , interventional occlusion with thin waist occluder was carried out in a total of 96 patients with perimembranous ventricular septal defect (VSD) complicated by pseudoaneurysm. The patient’s age varied from 2 years to 36 years. Before the procedure, routine left ventricular angiography and ascending aortic angiography were carried out. Left ventricular angiography and ascending aortic angiography as well as the transthoracic ultrasonography were performed immediately after the procedure to observe the therapeutic results. Follow-up checkups with transthoracic ultrasonography, EKG and chest X-ray film were conducted at one week as well as at one, 3, 6 and 9 months after the surgery were conducted. Results Successful occlusion of VSD was obtained in 93 patients, with a success rate of 96.8% (93/96). After the surgery, small amount of shunt flow was detected in 8 patients, which disappeared within 48 hours in 7 patients, and in the other one the shunt flow disappeared one month later which was confirmed by follow-up examination. After the treatment, complete right bundle branch block occurred in 4 patients, complete left bundle branch block in 5 patients, and transientⅢdegree atrioventricular block in one patient. The conduction block disappeared at the time of discharge in all patients. The left ventricular end-diastolic diameter (LVEDD) decreased from preoperative (47.5 ± 5.2) mm to postoperative (45.2 ± 5.1) mm, the difference was statistically significant (t = 18.33, P < 0.01). During the follow-up period lasting for 9 months, no delayed cardiac arrhythmia, valve damage or sudden death occurred. Conclusion For the treatment of perimembranous ventricular septal defect with pseudoaneurysm, interventional occlusion with thin waist occluder is safe and effective with excellent mid-term effect. Based on the imaging findings, including the location, shape, ruptured orifice, number of the perimembranous pseudoaneurysm as well as the distance between the pseudoaneurysm and the aortic valve, to select suitable occluder and proper occlusion site is the key to ensure a successful surgery.

BACKGROUND:The good rotational alignment of femoral prosthesis was very important in total knee arthroplasty. The research has shown that the posterior condylar angle was important to determine the alignment. The posterior condylar angle is the angle between the posterior condylar axis and the femoral epicondylar axis. MRI can clearly show the condylar cartilage, the projections of lateral epicondyle and the medial epicondyle depression, thus ensuring accuracy of measurement data. OBJECTIVE:To measure the posterior condylar angle of knee joint in the northern part of Baoding City in China, and to provide image evidence for identifying the rotational alignment of femoral prosthesis during total knee arthroplasty. METHODS:The knee was extended on a neutral position when MRI machine was applied to scan knee joint. The scanning plane was perpendicular to the mechanical axis of the knee. The best T1 axial plane of the knee was chosen, and two observers analyzed images independently. Existence rate of femoral medial epicondyle was observed using Bravo viewer 6.0 imaging software. The posterior condylar angle between posterior condylar axis and the femoral condyle axis was measured. RESULTS AND CONCLUSION:The posterior condylar angle was (2.73±1.28)° in males and (2.35±1.37)° in females on average, which did not show significant difference. The results showed that the MRI had great superiority in measuring the posterior condylar angle. The variability of the epicondylar axis was smal in total knee arthroplasty. Posterior condylar angle can be referenced to position femoral prosthesis and to avoid the complications after knee replacement.

Objective To explore a method for establishing stable auditory deprived animal model of mouse.Methods Forty two-month old BALB/c mice with normal auditory brainstem response(ABR) thresholds were divided into two groups randomly.The experimental group underwent an incision inferior to the pinna,and the cochleas were destoried with a drill through the bulla bilaterally.The control group underwent only an incision without cochlea ablation.Mice were tested for ABR thresholds 4 month later to assess hearing sensitivity by comparing the ABR before and after operation.Results In the experimental group,auricle reflection disappeared after operation and ABR waves couldn't be detect.In the control group,the result of hearing test was normal.Conclusion Mouse cochlea ablation is a reliable method for establishing a stable auditory deprived animal model of mouse by the pinna inferior approach.It can be used to the research of auditory centre plasticity induced by auditory deprived.

Objective To examine the effects of high-density lipoprotein(HDL) and lipoprotein-deficient serum(LPDS) isolated from patients with type 2 diabetes mellitus on cholesterol efflux through human skin fibroblast(HSF) and human hepatoma cell line(HepG2).Methods and Results Blood was collected from 13 patients with type 2 diabetes mellitus and 17 healthy volunteers,HDL and LPDS were isolated.Cholesterol efflux assays,RT-PCR and Western blot were performed with HSF and HepG2 cells.The HepG2 cells showed a high expression of scavenger receptor B1(SR-B1) and lack of functional ATP-binding cassette receptor A1(ABCA1) and ATP-binding cassette receptor G1(ABCG1) while HSF cells express SR-B1 at very low level and have a high expression of ABCA1 pretreated with 22-OH cholesterol.The cholesterol efflux from HepG2 cells to HDL isolated from patients with diabetes decreased significantly as compared to controls.However,cholesterol efflux from HSF cells to LPDS was not different between groups.Conclusion The function of HDL involving cholesterol efflux in type 2 diabetes mellitus was impaired while cholesterol efflux induced by LPDS from HSF cells was maintained,suggesting that HDL plays a critical role in mediation of intracellular cholesterol accumulation and progression of atherosclerosis inpatients with type 2 diabetes.

OBJECTIVE To investigate the different methods to calculate the rate of missing report on nosocomial infections.METHODS We had two methods to define the case of nosocomial infections,one was that the cases(infected) during the month we investigated,the other was that patients infected during the in hospital time.Then we got two different rates and "actually" nosocomial infection cases and compare the difference of the two results.(RESULTS) It was significant difference between these two results(P
