Design and application of the machine for cardiopulmonary resuscitation based on scissor lift principle without back plate / 中华危重病急救医学

Cardiopulmonary resuscitation (CPR) guidelines emphasize that external chest compression should be started as early as possible during CPR. In addition to manual hand compressions, the machine for CPR can be used instead. However traditional machines for CPR take a lot of time toinstall, and is not conducive to the early initiation of chest compressions. So the medical staff of the emergency department of Mindong Hospital Affiliated to Fujian Medical University designed a new type of machine for CPR based on scissor lift principle without back plate. The design has obtained the national utility model patent. This patented product with flexible lifting and accurate placement is easy to install and fix, and can overcome the drawbacks of conventional machines that are uneasy to install, thus ensuring the implementation of high quality CPR.

Effect of subtotal parathyroidectomy on secondary hyperparathyroidism in uremic patients / 中华内分泌外科杂志

Objective To study the clinical effect of subtotal parathyroidectomy on secondary hyperparathyroidism(SHPT) in uremic patients undergoing hemodialysis.Methods The data of 10 uremic patients undergoing hemodialysis who received subtotal parathyroidectomy from Jun.2006 to Jun.2011 in our hospital were retrospectively analyzed.Intact parathyroid hormone (iPTH),serum calcium,phosphorus and calcium-phosphorus product were analyzed statistically before operation,1 week,1 month,3 months,and 6 months after the operation.The joint pain relief and postoperative complications were studied.Results ①All of the 10 patients were successfully operated.No complication occurred.The intraoperative site of the parathyroid was consistent with that positioned by the preoperative B ultrasound guidance.②Postoperative bone pain and pruritus were obviously relieved.③iPTH decreased significantly at 1 week,1 month,3 months,6 months after surgery compared with that before surgery.The difference had statistical significance(P ＜ 0.05).④Postoperative serum calcium,serum phosphorus and calcium-phosphorus product decreased significantly at 1 week,1 month,3 months,6 months after surgery compared with that before surgery.The difference had statistical significance (P ＜ 0.05).Conclusions Preoperative localization for neck parathyroid by ultrasound scan is feasible.Subtotal parathyroidectomy can be effective in treatment of SHPT in uremic patients.The surgery were safe and with satisfactory treatment outcome.
