Objective To develope a new method producing ventricular septal defect (VSD) model by transcatheter puncture and evaluate its feasibility and practicability. Methods Ten dogs underwent transcatheter ventricular septal puncture with Brockenbrough puncture needle via right jungular vein under fluoroscopy, and then dilated the defect with 6-8mm balloon catheter. Left ventricular (LV) angiography was performed with pigtail catheter by transaortic access after puncture. Right after the procedure and 1-4 months later, the dogs were sacrificed and the defects were inspected. Results VSDs were successfully made in 8 dogs, which were demonstrated by LV angiography with one defect at membranous part. The defects in other dogs were shown near membranous septum or muscular septum not far away from the membranous part. The distance from aortic valves to the rims of defect was 4-16mm, from tricuspid valves 4-10mm. Ⅲ?AVB was found in 1 dog which died 1 week later, with ruptured membranous part at autopsy. CRBBB was found in another dog. Conclusion Establishment of VSD animal by transcatheter puncture is feasible, practicable and of high successful rate and less complication.

In order to lower the purchasing prices of drugs, prevent unhealthy tendencies that might arise in the process of drug circulation in the hospital, and reduce the financial burdens of patients, our hospital started from March 1997 the practice of purchasing drugs through open tender. The measures adopted include: ①establishment of a leading group in charge of drug purchases and a drug purchasing group; ②formulation and earnest implementation of the system of purchasing drugs through open tender, making “five checks”; ③standardization of the scope of routine drugs used in the hospital; and ④adherence to the system of examination and approval by the Drug Management Committee when introduction of new drugs is being considered. Since the adoption of the system of purchasing drugs through tender, the purc hasing prices of drugs have on the average dropped 14.7% and the drug expenses for single entity diseases have been lowered.

Objective To explore the clinical value of using pectoralis major myocutaneous flap in surgery with various adverse factors for advanced oropharyngeal cancer.Methods 15 patients who presented with advanced oropharyngeal cancer were performed for radical surgery,and pectoralis major myocutaneous flaps were applied for immediate reconstruction of surgical defect.In all cases,various adverse factors(advanced age,diabetes,cardiovascular disease,radiation damage,etc.)were existed.The effect of reconstruction was observed.Results All surgeries were successful,and all patients tided over perioperative period.The average time of operation was 5 hours with a range of 4 to 6 hours.The average time cost for flap preparation was 40 minutes with a range of 40 to 55 minutes.The completely survival rate of flaps was 93%.Partial skin necrosis occurred in 1 case(7%);and submandibular fistula occurred in another one(7%).Two patients(13%)developed wound infection.All of them were healed by symptom-atic treatment.Conclusion For the patients with advanced oropharyngeal cancer and various adverse factors of sur-gery,pectoralis major myocutaneous flap can be used as salvage measure in reconstruction of surgical defect,which is more secure than free flap.

Objective To investigate the effeit of Reconstruction of tantalum metal rod implantation in the treatment of early ischemic necrosis of femoral head( Steinberg Ⅰ~Ⅱ period) ,to explore the early femoral head ischemic necrosis of minimally invasive treatme(n)t. Method 24 patients( Steinberg Ⅰ~Ⅱ period) using C-arm fluoroscopy machine,under the greater trochanter through the neck hole to avascular necrosis zone,the first zone of the medullary sclerosis core decompression, re-implantation of tantalum rod to the subchondral bone is about 0.5 cm, through the Harris score before and after surgery for comparison. Results After follow-up 9(2 ~ 12) months,preoperative pain and function were significantly limited nuitigation. The excellent rate was 83% after opertion. MRI manifestations in patients with stable,non-ischemic necrosis increased performance. Conclusion Core decompression can significantly reduce the pressure on the femoral head hardening region, tantalum rod weight-bearing area of femoral head implant provides a structural support for subchondral bone. This method has the characteristics decompression,structural support,minimally invasive,it is worth for clinical use.

BACKGROUND: Bone morphogenetic protein (BMP) and its derived scaffold or vector here been widely used in experiment and gradually applied in the clinic. However, the tracing method challenges the therapeutic effect, The discovery and application of enhanced green fluorescent protein (EGFP) can solve this problem.OBJECTIVE: To construct the bicistronic eukaryotic vector pIRES2-EGFP-hBMP-2 and to observe its expression in human embryo kidney (HEK) 293 cells.METHODS: hMBP-2 gene was extracted from human osteosarcoma by RT-PCR and inserted into PMD18-T vector. Following the DNA sequence verification, it was then sub-cloned into the eukaryotic vector pIRES2-EGFP. After restriction enzyme analysis the pIRES2-EGFP-BMP-2 was transfected into HEK 293 cells. Then its expression was observed using fluorescence microscopy and Western blot.RESULTS AND CONCLUSION: hBMP-2 gene was amplified and the eukaryotic vector plRES2-EGFP-hBMP-2 was constructed successfully. At 48 hours after tranfection of pIRES2-EGFP-hBMP-2 into HEK 239 cells, approximately 30% of cells emitted green fluorescence under a fluorescence microscope. Western blot results demonstrated that there was a specific BMP strap at Mr46×10s side, which indicated that the target gene could be expressed in constructed pIRES2-EGFP-hBMP-2 vector.

Objective To analyze the changes of bone mineral density (BMD) and the incidence of osteoporosis in elderly people in Xuzhou area by measuring BMD, and provide reference to osteoporosis prevention and control. Methods From 2005 to 2008, BMD were measured in 1204 elderly people by dual energy X-ray absorptiometry (DEXA). The measurement included the neck of femur and L2-4 of lumbar. All subjects were divided into multiple sections with every 5 year interval. Osteoporosis was diagnosed according to the criteria of BMD peak minus 2. 5 SD. BMD values and the incidence of osteoporosis were analyzed among different age and gender groups. Results BMD of different sites decreased year by year in both male and female in Xuzhou area. After 55years of age BMD decreased more in female than in male ( P < 0. 01 ). The incidence of osteoporosis in female was higher than that in male. Conclusions We should reinforce the health education on osteoporosis prevention. Intervention should be conducted in females older than 55 years and males older than 65 years to decrease the occurrence of osteoporosis.
