BACKGROUND： With advances in technology, laparoscopic liver resection is widely accepted. Laparoscopic liver resection under hemihepatic vascular inflow occlusion has advantages over the conventional total hepatic inflow occlusion using the Pringle＇s maneuver, especially in patients with ***： From November 2011 to August 2012, eight consecutive patients underwent laparoscopic liver resection under hemihepatic vascular inflow occlusion using the lowering of hilar plate approach with biliary bougie ***： The types of liver resection included right hepatectomy（n1）, right posterior sectionectomy（n1）, left hepatectomy and common bile duct exploration（n1）, segment 4b resection（n1）, left lateral sectionectomy（n2）, and wedge resection（n2）. Four patients underwent right and 4 left hemihepatic vascular inflow occlusion. Four patients had cirrhosis. The mean operation time was 176.3 minutes. The mean time taken to achieve hemihepatic vascular inflow occlusion was 24.3minutes. The mean duration of vascular inflow occlusion was54.5 minutes. The mean intraoperative blood loss was 361 *** patient required blood transfusion. Postoperatively, one patient developed bile leak which healed with conservative treatment. No postoperative liver failure and mortality occurred. The mean hospital stay of the patients was 7 ***： Our technique of hemihepatic vascular inflow vascular occlusion using the lowering of hilar plate approachwas safe, and it improved laparoscopic liver resection by minimizing blood loss during liver parenchymal transection.

Extrapyramidal movement disorders are common in chronic schizophrenia, and may be an intrinsic feature of the illness as well as related to antipsychotic drug treatment. Similar dysfunctions at illness onset may have implications for outcome, and for under- standing the mechanisms of illness. The objectives were to examine the clinical correlates of pre-treatment movement disorders at first episode of psychosis, and determine associations with neuropsychological function and striatal structure. Never medicated subjects were recruited from consecutive admissions to Early Psychosis Programs with defined catchment areas in Hong kong, China, and Halifax, Canada. Standardized clinical, neuropsychological and brain imaging assessments were carried out at baseline and following acute and long term treatment with typical or atypical antipsychotic drugs. At the Hong kong site, we studied 84 subjects with first episode psychosis (n = 10 with EPS). At the Halifax site, we studied 40 subjects with first episode psychosis (n = 17 with EPS), and 23 healthy comparison subjects. Subjects with movement disorders prior to treatment (EPS+) had higher total PANSS scores at baseline (mean elevation 19.9% Hong kong, P = 0.016; 14.7% Halifax, P = 0.049). In subjects treated with atypical antipsychotics (all Halifax), EPS+ status at baseline predicted more movement disorders at long term follow up (P = 0.0005). In both cohorts, EPS+ subjects had poorer acute symptomatic treatment response assessed with the PANSS (Hong kong P = 0.005; Halifax P = 0.017). Neuropsychological impairment related to executive dysfunction appeared greater in a small sam- ple of EPS+ subjects (Hong kong, effect size 0.26-0.27, P < 0.05). Caudate volumes were 4.5% larger in EPS+ compared with EPS-subjects (Halifax P = 0.042), and correlations between striatal volumes and age were different in the EPS+ group. In conclu- sion, pre-treatment EPS is present in a substantial minority of subjects with first episode psych

Objective： To systematically review the clinical practice guidelines （CPGs） for ischemic stroke in Chinese medicine （CM） with the Appraisal of Guidelines for Research and Evaluation （AGREE II） instrument. Methods： CM CPGs for ischemic stroke were searched in 5 online databases and hand-searches in CPG- related handbooks published from January 1990 to December 2012. The CPGs were categorized into evidence based （EB） guideline, consensus based with no explicit consideration of evidence based （CB-EB） guideline and consensus based （CB） guideline according to the development method. Three reviewers independently appraised the CPGs based on AGREE II instrument, and compared the CPGs＇ recommendations on CM pattern classification and treatment. Results： Five CM CPGs for ischemic stroke were identified and included. Among them, one CPG was EB guideline, two were CB guidelines and two were CB-EB guidelines. The quality score of the EB guideline was higher than those of the CB-EB and CB guidelines. Five CM patterns in the CPGs were recommended in the EB CPG. The comprehensive protocol of integrative Chinese and Western medicine recommended in the EB CPG was mostly recommended for ischemic stroke in the CPGs. The recommendations varied based on the CM patterns. Conclusion： The quality of EB CPG was higher than those of CB and CB-EB CPGs in CM for ischemic stroke and integrative approaches were included in CPGs as major interventions.

目前机器学习仍属于纯数据驱动下的单一数据学习,其结果和学习过程的物理可解释性有待提高。在油气田开发中,井网密度较小,井点数据属于稀疏训练样本数据,即使采用深度学习,其预测效果仍欠佳。油气流动物理过程一般较为明确,即满足渗流方程,将渗流方程作为约束条件加入深度学习损失函数项,建立一种考虑物理过程信息的油气渗流深度学习新模型。通过单相和两相流算例验证模型的正确性和高效性。结果表明:在数据样本充足情况下,无论是传统模型还是新建模型均能获得良好的学习和预测效果;随着数据样本的减少,传统模型的学习和预测结果误差也随之增大,但新建模型仍能保持较高精度,即使在强非均质和注采关系反转条件下也能保证预测精度。

Company bankruptcies cost billions of dollars in losses to banks each year. Thus credit risk prediction is a critical part of a bank＇s loan approval decision process. Traditional financial models for credit risk prediction are no longer adequate for describing today＇s complex relationship between the financial health and potential bankruptcy of a company. In this work, a multiple classifier system （embedded in a multiple intelligent agent system） is proposed to predict the financial health of a company. In our model, each individual agent （classifier） makes a prediction on the likelihood of credit risk based on only partial information of the company. Each of the agents is an expert, but has limited knowledge （represented by features） about the company. The decisions of all agents are combined together to form a final credit risk prediction. Experiments show that our model out-performs other existing methods using the benchmarking Compustat American Corporations dataset.
