Objective To observe the reparative response and expression of basic fibroblast growth factor (bFGF) protein in the rotator cuff subjected to subacromial impingement. Methods Subacromial impingement of the infraspinatus tendon was experimentally created in 50 male SD rats by thickening the undersurface of the acromion with one platelike bony transplantation of the ipsilateral scapular spine. The contralateral shoulders that had undergone a sham operation were used as controls. The rats were sacrificed at 3, 7, 14, 28, and 56 th day, the whole shoulder joint was removed for detecting bFGF protein and the reparative response in the impinged infraspinatus tendon. Computer image analysis system were used to monitor the expression intensity and numbers of positive cells of bFGF protein. The OD scores and the size of area represent the expression intensity and numbers of positive cells respectively. Results All rats with experimental subacromial impingement showed an infraspinatus tear on the bursal side of the tendon. The shoulders in the control group were found intact without any alteration. There was proliferating cells in the fragmented tendons and vascularised connective tissue covering the area of ruptured area, whose source was the subacromial bursa. Few tenocytes and bursal cells expressed bFGF protein in unwounded tendons. In contrast, tendons subjected to impingement exhibited an increased signal for bFGF protein in both resident tenocytes concentrated along the epitenon and infiltrating fibroblasts and inflammatory cells from the subacromial bursa. Conclusion The bFGF protein is upregulated during tendon healing and the subacromial bursa is the main source of both bFGF secreting and rotator cuff repair; one should preserve as much as possible the subacromial bursa.

Objective To explore the consistency of knee articular cartilage defect area by magnetic resonance imaging (MRI)and arthroscopy.Methods Thirty-six patients (36 knees)with knee cartilage lesions were collected in our study.The defect area meas-urement of knee articular cartilage by MRI and arthroscopy was compared.Results A total of 92 lesions were detected by both MRI and arthroscopy with an average of 2.6 defects per knee.Preoperative MRI resultes demonstrated the mean defect area per knee was (1.9±1.5)cm2 ,while arthroscopic measurement after debridement indicated the mean defect area per knee was (2.9±2.6)cm2 , which had significant difference(P <0.001).The area measured by MRI was less than that by arthroscopy,and the mean difference was (1.7 ± 1.1)cm2 .The mean area measured by MRI was 70.1% of that by arthroscopy.Conclusion Arthroscopy and MR have good consistency in the number of articular cartilage defect lesions .MRI can reflect the knee articular cartilage defect area directly or indirectly,and be capable of accurate positioning and qualitative diagnosis.

Objective To retrospectively study the perioperative complications and postoperative function recovery of 93 patients treated with simultaneous bilateral total hip arthroplasty (THA). Methods A total of 93 patients (186 hips) undergone simultaneous bilateral THA from January 1999 to January 2009 in our hospital were involved in this study. There were 70 males and 23 females (at age range of 25-65 years, average 41. 8 years). The preoperative diagnosis included bilateral avascular necrosis of femoral head in 48 patients, rheumatoid arthritis in 11, developmental dysplasia of the hip in 26 and ankylosing spondylitis in 8. The intraoperative blood loss, Harris scores before operation and at final followup as well as perioperative complications were analyzed. Results All the patients were followed up for average 65 months (12-118 months), which showed femur fracture in one patient and infection six months after discharge in one patient. The Harris score was increased from (36.7 ±6.1) points preoperatively to (91.2±6.2) points at the final follow-up. Hip pain disappeared in 92 patients after operation and radiograph showed no loosening. Actebular loosening occurred in one patient 49 months after operation and was revised accordingly. Conclusion Under strict control of operation indications, suitable choice and implantation of the prosthesis and emphasis on perioperative management and postoperative rehabilitation, simultaneous bilateral THA is a safe and effective choice for bilateral hip diseases.
