ObjectiveTo investigate the early diagnosis and treatment of pleuropulmonary blastoma in children. Meth-ods The progress of pleuropulmonary blastoma from type 1 to type 3 was retrospectively analyzed.Results The male infant had no obvious abnormality in chest X-ray at 18 days. At one year old, X-ray iflm of the chest showed cystic lesions near hilum of the left lung (about 5 cm × 4 cm × 4 cm). The congenital cystic adenomatoid malformation was considered and an operation resection was suggested. However, it had been rejected by his parents. At 3 years and 2 months old, chest X-ray and CT showed left lung had a solid cystic lesion, the volume was signiifcantly enlarged, the back side was solid and the upper part had a large gas cavity. Two months later, the patient had asthmatic suffocation. The chest CT showed the tumor was completely solid. Pleuropulmonary blastoma type 3 was considered. The patient received the conventional chemotherapy after operation excision, and was followed up for 1 year. No recurrence was observed after the treatment.Conclusions Type 1 pleuropulmonary blastoma and congenital cystic adenomatoid malformation are hard to be differentially diagnosed. Early diagnosis and treatment of type 1 pleuropulmo-nary blastoma can improve the prognosis.

Objective One of the characteristics of rheumatoid arthritis was multiple joints involved symmetrically. The purpose was to study the method of early diagnosis and treatment for the atypical rheumatoid arthritis involving solitary joint. Methods From April 1997 to December 2002, 5 cases which were 1 male and 4 female patients with an average age of 36.8 years (range, 23 to 47 years), suffered from the swelling and pain of knee joint, and were diagnosed as early rheumatoid arthritis. The interval of the onset to surgical treatment ranged from 2 months to 3 years with a mean of 16.2 months. The patients were evaluated with serum test, joint fluids examination and radiological imaging. They were treated by the synovectomy under the arthroscopy, while the appearances of the joint under arthroscopy were recorded, and the synovial tissue was sent to the pathological examination. The improvements of the joints symptoms and the range of motion were assessed at final follow up. Results During the operation, the light green and little muddy joint fluids were found in all patients. ESR of the patients ranged from 29 to 51 mm/1h with an average of 32.2 mm/1h, all of which were higher than normal value, whereas, 3 cases had positive rheumatoid factor and 4 cases showed significant higher ?2-MG. The radiographic findings were osteoporosis in 3 cases, soft tissue swelling in 4 cases and narrowed joint space in 1 case. The synovium were proliferated and enlarged in dark violet, there were creeping pannus and necrosis fibrin deposition in the cartilage. All of the patients were diagnosed as rheumatoid arthritis confirmed by pathological changes of the synovium. The patients were followed up from 4 months to 5 years (mean, 18.7 months). Pain released in 5 cases, swelling reduced in 3 cases, the range of motion improved by 19 degrees. Unfortunately, all of the patients developed later into typical rheumatoid arthritis after the mean interval of 10.9 months (range, 3 to 25 months), the symptoms were consistent with the criteria of American Rheumatoid Association . Conclusion Solitary joint with rheumatoid arthritis is rare and may be the early status of rheumatoid arthritis. The specific appearance under the arthroscopy prompt the early diagnosis of the knee rheumatoid arthritis, and synovectomy by arthroscopy may be benificial to release the symptoms of rheumatoid arthritis.

Objective To evaluate the efficacy of total hip replacement in patients with ankylosing spondylitis(AS) and to solve the problem often encountered during surgery. Methods One hundred and twelve hips of 98 patients with AS undergone total hip replacement were reviewed. The mean duration of follow up was 4.2 years(range, 1.5 to 8 years). The pre and postoperatively comparative study on pain, range of motion, correction of deformity and total function evaluation were conducted. Results Pain relief obtained in all but 4 hips. Mean range of motion was improved from 37.5? to 69.5? and the flexion deformity of the involved hip was corrected from mean 38.2? to 5.7?， all of the patients could take care of daily living by themselves. Complications included penetrating fracture of proximal femur in 4, sciatic nerve injury in 3, early dislocation of the hip in 2, disassociation of the acetabular component in 2 and sinking of the femoral stem in 23. Conclusion Total hip replacement is a very important and effective treatment of choice for patients with AS. The modified combination of anterolateral and lateral approach used by the authors facilitated release of contracture of the soft tissue anterior to the hip joint and correction of flexsion deformity of the hip. In case of multiple joint involvement, the surgery should be performed on the most severely involved one and the next surgery, if required, should be scheduled later within 3 to 6 months.

Objective To investigate the possibility、 efficacy、 safety of the repair of infarcted myocardium and improvement of cardiac function by intracoronary autologous mononuclear bone marrow cell (MBMC) transplantation in patients with AMI. Methods Thirty-eight patients with AMI were enrolled in this prospective study and divided into PCI+cell transplantation group and PCI only group. Baseline and follow up evaluations included complete clinical and laboratory evaluations, 2D echocardiogram, positron emission tomography (PET), 48 ECG monitoring. MBMC were harvested, isolated, washed, and resuspended in saline for infusion. 21 patients were transplanted with autologous MBMC via a balloon catheter placed into the infarct-related artery during balloon dilatation by highpressure infusion 14.6 days after AMI, which was performed 6-8 times for 2 minutes each and 7 patients were transplanted via non-selective infarct-related arteries by highpressure infusion. Results Surgery was safe. 3 patients had limited premature ventricular contractions during cell infusion for several seconds. 3 patients felt cold after 15-30 minutes infusing cell. After 3 months of fellow-up, there were viable myocardium in the infarct defected regions in 13 cases after MBMCs transplantation determined by PET, which occupied [(40.08?8.82%), P
