Hepatic ischemia/reperfusion injury is an important restricting factor of clinical liver resection and liver transplantation.When the liver is transiently deprived of blood followed by repeffusion,a large number of various mediators are released that can lead to cellular and,eventually,organ dysfunction.This review summarizes the pathogenesis and the protection mechanisms of hepatic ischemia/reperfusion injury.

Objective To investigate and analyze clinical obstetrics and gynecology clinicians' mastery of basic skills, and then find the way to help clinicians master basic clinical skills. Methods A self-designed questionnaire survey was conducted among 310 clinicians working in 1-3 grade hospital from Chongqing, Sichuan, Guizhou, Yunnan provinces anonymously by spot field investigation and letter-investigations from February 1, 2015 and to March 31, 2015. The data were analyzed by descriptive analysis, using SPSS 19.0 software package for rank sum test analysis. Result Among 310 valid questionnaires, 31.6% (98) clinicians considered having inadequate clinical skills, 26% (81) average and 42.3%(131) expert. All the basic skills obtained had a relationship with the number of operations, working years and professional title. Most of the basic clinical skills were from working in hospitals 85% (270), journal 82% (254), academic conference 58% (174); 94.2% (293) willing to participate in training classes like clinical teaching and training in moulds. Conclusion The gynecology and obstet-rics basic clinical skills have a great relationship with basic skills training. Providing opportunities for the basic clinical skill trainings, academic conferences, in-service education and establishing regional medical source sharing platform can enhance their clinical skills.

Objective To evaluate the clinical efficacy of Qilinxintongshu pill for treatment of critical patients with unstable angina pectoris (UAP) accompanied by upper alimentary tract damage.Methods A prospective randomized controlled trial was conducted. A total of 60 critical outpatients or inpatients with confirmed diagnosis of UAP accompanied by upper alimentary tract damage in Cardiology Department of Hospital of Traditional Chinese Medicine of Qionghai City from November 2011 to January 2015 were enrolled in the study, and they were assigned to a therapy group (30 cases) and a control group (30 cases) by table of random number. The conventional medical basic therapy was given to both groups, in addition, the patients in therapy group took Qilinxintongshu pill (made of notoginseng, dragon's blood, fruit of immature citron, etc.) 5 g once, three times a day, and the patients in control group orally administered clopidogrel 75 mg once a day, the therapeutic course being consecutive 30 days. After treatment, the rates of main cardiovascular events [including death, a newly-happened myocardial infarction (MI), and obstinate ischemia] and events of alimentary damage were compared between the two groups, and adverse effects were observed.Results There was no statistically significant difference in incidence of cardiovascular events between the therapy group and control group [6.7% (2/30) vs. 16.7% (5/30),P > 0.05]. The incidence of massive hemorrhage of gastrointestinal tract was significantly lower in therapy group than that in control group [10.0% (3/30) vs. 36.7% (11/30),P < 0.05]. In the treatment process, there was no significant untoward side effect, and no abnormalities in routine blood and urine tests, liver and renal functions were found.Conclusion Qilinxintongshu pill for treatment of critical patients with UAP accompanied by upper alimentary damage is safe and effective, and does not enhance the incidence of massive hemorrhage of gastrointestinal tract.

Objective To develop a MOSAIQ Integration PlatformCHN (MIP) based on the workflow of radiotherapy (RT) and to meet the actual requirements in China and the special needs for the radiotherapy department.Methods MIP used C/S (client-server) structure mode running on the local network in the hospital and its database was based on the Treatment Planning System (TPS) and MOSAIQ database.Five network servers,as the core hardware,supplied data storage and network service based on cloud services.The core software was developed based on Microsoft Visual Studio Platform using C# network programming language.The MIP server could simultaneously offer network service for about 200 workstations,including entry,query,statistics,and print of data.Results MIP had 15 core function modules,such as Notice,Appointment,Billing,Document Management (application/execution),and System Management,which almost covered the whole workflow of radiotherapy.Up to June 2016,the recorded data in the MIP were as follows:13546 patients,13533 plan application forms,15475 RT records,14656 RT summaries,567048 billing records,and 506612 workload records.Conclusions The MIP based on the RT workflow has been successfully developed and used in clinical practice.It is an important part of radiotherapy information system construction with the advantages of intuitive operation,real-time performance,data security,and stable operation.It is digital,paperless,user-friendly,and convenient for the retrieval and statistics of data as well as information sharing and department management,and can significantly improve the efficiency of the department.More functions can be added or modified to enhance its potentials in research and clinical practice.

Cone-beam computed tomography (CBCT) image based on a single layer of image and the choice of regions of interest (ROI) is affected by individual subjectivity, making it difficult to compare the image quality. In this article, a quantitative evaluation method of CBCT image quality based on three-dimensional parameters was proposed, which was extended from single layer to multi-layer and from pixel to voxel. The selection range of ROI was discussed to reduce the error of artificial selection and realize the quantitative evaluation of image quality by three-dimensional parameters.
