There were no false positive reports among the 220 (40.1%) biopsies interpreted as benign lesions in paraffin sections. Among 329 (59.9%) malignant biopsies on paraffin sections, 3 cases were interpreted as benign lesions on frozen sections. Three false negatives included 2 ductal carcinoma in situ and one infiltrating ductal carcinoma associated with papillomatosis. The tumors were small and confined to the breast without any evidence of metastasis.

Chi-square test indicated that there was no significant difference compared to human patch test.

与人体斑贴试验结果经校正χ2 检验比较，差异无显著性意义，其灵敏度、特异度、阳性预测价值、阴性预测价值均为1。

Methods Total of 164 patients with first-episode schizophrenia were evaluated before treatment, at the end of 12 weeks treatment and then annually till 5 years on 10 cognitive function tests, including Weschler adult intelligence scale, Weschler memory scale, grooved pegboard test, finger tapping test, motor function test, hand coordination test, trail making test A and B, Wisconsin card sort test, and verbal fluency test, together with BPRS, SANS and GAF. Results The scores on all cognitive function tests were not significantly related to total scores of BPRS, SANS and GAF before treatment.

对164例首发精神分裂症患者进行随访观察，于治疗前、治疗12周末、治疗1年末、2年末、3年末、4年末、5年末各做1次韦氏成人智力量表、韦氏记忆量表、铁槽铁钉测验、手指敲击试验、动作功能测验、手功能协调测验、连线测验A和B、威斯康星卡片分类测验及言语流利性测验等10项神经心理测查及简明精神症状评定量表、阴性症状评定量表、功能总体评定量表评定。

After 48 hours pre-induction, the percentage of nestin was 24%, which was 4.6% in the control group. After 48 hours induction, BMSCs exhibited the typical form of perikaryon with pyknotic cell body and prominence projected like that of neuron.

诱导48 h后，巢蛋白染色呈阳性，并可见大量神经元特异性烯醇化酶和胶质纤维酸性蛋白阳性细胞出现；对照组均呈阴性表达。

Essential oil was extracted from the petroleum ether-soluble fraction of the leaves showed having antibacterial activity. It was demonstrated that the essential oil has significant antibacterial activity and the activity of the petroleum ether-soluble fraction is attributed to it. The constituents of the essential oil were analysized by GC-MS.10 relatively abundant components were identified on the basis of MS, among which Geranlgeraniol was found in the essential oil of Perilla frutescens leaves for the first time.

对具有抗菌活性的紫苏叶石油醚萃取物进一步精制，从中提取出挥发油，通过抗菌测试证明紫苏叶挥发油具有良好的抗革兰氏阳性菌和革兰氏阴性菌活性，是紫苏叶石油醚萃取物抗菌活性的来源；采用GC-MS对紫苏叶挥发油进行了成分分析，得到10种含量较高的主要化合物，其中的牻牛儿基牻牛儿醇首次在该植物挥发油中被发现。

We detected the PERV DNA and RNA by PCR and RT-PCR.

检测混合型人工肝支持系统术前病人的血清均呈阴性。

Methods During the period from October 2002 to October 2004, the patients whose HPD tests were negative were treated with photodynamics method by using HPD in vitro irritated.

方法我们于2002年10月至2004年10月，选血卟啉衍生物皮试阴性患者，采用体外激活HPD的方法开展光动力学治疗。

"One of the difficulties — still — is in making the clinical decision of whether a child has type 1 or type 2 diabetes," Dr. Bennett explained. There are several characteristics that differentiate the two. Dr. Bennett reported that among the Pima, 92% of children with type 2 diabetes also had a family history of type 2 disease, most often in the mother. Other features include obesity (body mass index of 30 kg/m2 or greater),(68%), being asymptomatic (78%), and ketoacidosis (about 10%). These children and adolescents are not insulin-dependent and may stay that way for years, he said. They are also glutamic acid decarboxylase antibody– and islet cell antibody–negative.

Bennett博士解释道，在临床上决定孩童是第一型或是第二型糖尿病是有困难的，两者之间是有不同的特点，Bennett博士提到，在印地安人身上，92%的孩童发生第二型糖尿病是有家族史的，且与母亲有关，其他特徵还包括肥胖（身体质量指数大於等於30 kg/m2）占68%、无症状占78%、酮酸血症约占10%；Bennett博士指出，这些孩童与青少年并非胰岛素依赖型且持续好几年，他们在麸氨酸脱羧酶抗体与胰岛细胞抗体是呈阴性反应。
