Ve schizophrenic inpatients will be enrolled into the 6-week, randomized, double-blind trial of sarcosine monotherapy (1000~3000 mg/day, N=75) vs. risperidone (2~6 mg/d, N=75). We will measure clinical efficacy and side effects biweekly during the treatment. At the beginning and the end of the trial, we will also measure cognitive function (e.g. intellect, attention, memory, executive function), serum amino acids, expressions of mRNA (by realtime quantitative RT-PCR) and protein of NMDA-related genes (such as SHMT2, AMT, PSAT1, ASCT1, and serine racemase) in peripheral blood lymphocytes.

为减少肠管膀胱术的并发症，于1994年3～7月，用犬分三组作了膀胱粘膜点状移植于浆肌层肠段重建膀胱的实验。A组：自体膀胱粘膜点状移植于浆肌层肠段形成人工膀胱，B组：在A组基础上一期将输尿管与人工膀胱吻合，C组：将同种异体膀胱粘膜移植于浆肌层肠段。

Methods and Results-: We enrolled 142 patients randomized at a single center to have either the radial artery or saphenous vein grafted to a stenosed branch of the native left circumflex coronary artery. The primary end point was angiographic graft patency 5 years postoperatively.

To systematicallyinvestigate this landmark, we conducted a study in four phases:1 Two blindfolded examiners determined the distance betweenthe tuberosity's medial border and the clavicle's lateral endin 100 dried clavicles and then 2 performed subclavian veincannulation in 20 fresh human cadavers using the tuberosityand the suprasternal notch as landmarks. 3 Three-dimensionalreconstructions of the subclavian artery and vein and surroundingstructures were derived from computed tomography datasets of10 patients. The length of the path of a virtual subclavianvein cannulation with the deltoid tuberosity landmark was measuredbilaterally. 4 In a prospective, randomized trial, subclavianvein cannulation was performed in 60 patients with a standardapproach or with the deltoid tuberosity as landmark.
