Selection of neuromuscular blocking agents in patients undergoing renal transplantation under general anesthesia.
To study the pharmacodynamics of vecuronium,atracurium, mivacurium and rocuronium in patients with end-stage renal failure. ⋯ All four muscle relaxants could be safely used in patients with end-stage renal failure. Onset of the relaxants were, in some cases, accelerated and no-response period of mivacurium was prolonged in patients with end-stage renal failure undergoing dialysis therapy. End-stage renal failure prolonged the no-response period and duration of action of vecuronium and rocuronium after repeated incremental doses, but did not alter those attributed to atracurium.

Retrospective analysis of 67 consecutive cases of pure ovarian immature teratoma.
To investigate the development regularity, treatment methods and prognosis of ovary immature teratoma (POIT). ⋯ POIT is a potentially curable disease in today's practice. It is characterized by the fact that recurrent tumors may be converted back to mature ones as time goes on. With chemotherapy, these is a good opportunity to rescue those patients with recurrent tumors. At present, treatment of POIT gives the most satisfactory results among all malignant ovarian germ cell tumor types. Tests of serum specific tumor markers (CA19-9, AFP, CA125, CEA) performed preoperatively or before chemotherapy and during follow-up have been found helpful in the evaluation of prognosis.

Clinical application and histological observation of pedicled buccal fat pad grafting.
To introduce the applied anatomy of pedicled buccal fat pad (BFP) graft and a series of histological changes in the healing process of BFP as an uncovered pedicled graft. ⋯ Advantages of the pedicled buccal fat pad graft include an anatomic region that is consistent and easy to excise. The operation can be performed in one incision, affecting neither appearance nor function of the area. Use of the buccal fat pad provides a good reconstruction of soft tissue defects in the mouth.

Prediction of pulmonary arterial wedge pressure from arterial pressure or pulse oximetry plethysmographic waveform.
To assess the possibility of using arterial pressure waveform or pulse oximetry plethysmographic waveform variation to estimate the pulmonary arterial wedge pressure (PAWP). ⋯ During positive pressure mechanical ventilation, APR, SPV, dDown, SPV(plet) and dDown(plet) can be used to estimate PAWP effectively.

Diagnostic significance of ultrasonography and CT for large upper abdominal mass.
To assess the effect of ultrasonography and computerized tomography (CT) in the diagnosis of large upper abdominal mass. ⋯ Because upper abdomen organs are closely connected with each other, correct imaging localization of a large mass in this region is not easy. In this study, we compared the accuracy of ultrasonography and CT in diagnosing large upper abdominal masses, and found that ultrasonography works better for adrenal rather than liver or kidney. Neither ultrasonography or CT could accurately diagnose a large mass in the spleen.
