Objective:To establish a determination method for the content and entrapment efficiency of ropivacaine hydrochloride-loaded multivesicular liposomes. Methods: The separation of the multivesicular liposomes from the free drug was achieved by low-speed centrifugation. The concentration of ropivacaine hydrochloride in the supernatant and the multivesicular liposomes was determined by HPLC, and the entrapment efficiency was calculated. Results: The linear range of ropivacaine hydrochloride was 1. 0-80. 0μg· ml-1(r=0. 999 8). The average recovery was 99. 95% and RSD was 0. 72%(n=9). The content and entrapment efficiency of three batches of ropivacaine hydrochloride-loaded multivesicular liposomes was within the range of 99. 1%-100. 3% and 80. 06%-82. 14%, respectively. Conclusion:The method is simple and accurate, and can be used in the determination of content and entrapment efficien-cy of ropivacaine hydrochloride-loaded multivesicular liposomes.

Objective To investigate the effectiveness of Rh-negative patients receiving Rh-positive renal grafts.Methods Three Rh-positive kidneys were transplanted in 3 Rh-negative uremia patients respectively. The pre- and intraoperative conditions were evaluated. All patients were regularly followed up.Results Dysfunction occurred in one graft kidney 5 years after the operation, and the patient died of cardiovascular complication 8 years after the operation. The remaining 2 patients have survived 22 and 2 months respectively with normal renal function, and their Rh antibodies were negative 21 and 2 months after the operation respectively.Conclusion Fully perfused Rh-positive renal grafts can be transplanted to Rh-negative uremia patients. The short-term effect is satisfactory.

Objective To discuss the individual method and its feasibility and security of balloon kyphoplasty for the treatment of osteoporotic vertebral fractures with vertebral body wall incompetence. Methods Thirty-nine vertebral bodies were performed for kyphoplasty in 35 osteoporotic patients with vertebral compression fractures with incompetence of vertebral body wall. During operation, the cement was injected twice to avoid anterior leaking in the patients with anterior wall incompetence, while in the patients with posterior or lateral wall incompetence, the cement was injected with continuously X-ray monitoring by C-arm to prevent lateral or posterior leaking. The symptoms improvement, vertebral height restoration and complications were observed. Results All patients tolerated the procedure well with immediate relief of back pain after kyphoplasty. No symptomatic complications were found in all patients. The vertebral height had a recovery rate of 68.46%, and the mean Cobb angle was improved 8.6?. There was significant difference in Cobb angles between preoperation and postoperation (P
