Merely having complete sequences of genomes is not sufficient to elucidate biological function. Proteomics is complementary to genomics because it focuses on the large scared gene products, which are the active agents in cells. As almost all the drugs are directed against proteins, proteomics have been widely used in pharmacological research.Proteomics profiling in drug target identification, toxicological and drug resistances research was reviewed.

Objective To further develop SDE for structured documentation of clinical data based on medical ontology. Methods OpenSDE was customized for the broad domain of medical ontology: medical concepts and its descriptors from history taking and physical examination were modeled into a tree structure. Results An expandable EMR system with structured data entry was developed. Conclusion Structured data entry is significant to clinical decision based on EMR.

Objective:To evaluate the reliability and accuracy of 3DSS-Ⅱ color structured-light scanning system for scanning and reconstructing the model of abutment tooth.Methods:5 plaster maxillary abutment tooth models were scanned and reconstructed by 3DSS-Ⅱ color structured-light scanning system,and then the 3D shapes of the models were measured by Geomagic 6.0 software and the plaster models were measured by manual with vernier caliper.The data were statistically analyzed.Results:The graphs of point-cloud were obtained from scanning surfaces of abutment tooth models.There were close correlations and no significant differences between different groups(r≈1,P

Objective To focus on the expressiveness and flexibility of OpenSDE: an application that supports recording of structured narrative data. Methods OpenSDE enabled data entry with (customizable) forms based on trees of medical concepts. The relevant scope for data entry could be tailored per medical domain by construction of a domain-specific tree. OpenSDE was intended for structuring narrative data to make these available for both care and research. Results The OpenSDE application was used at two departments in aspects of radiology, neurology, pediatrics, and child psychiatry. Conclusion OpenSDE is superior to traditional text entry method in aspects of correct and full expression and clinical decision support.

Purpose To investigate the correlation of the expression of Cyclin D1 and BRAF ( V600E) mutation in papillary thyroid carcinoma ( PTC) and their clinical significance, and to analyze their role in the pathogenesis of PTC. Methods The expression of CK34βE12 and MC protein was detected by immunohistochemical EnVision method in 52 cases of PTC and 52 cases of thyroid benign lesions (25 cases of nodular goiters, 15 cases of Hashimoto’s thyroiditis, 12 cases of follicular adenoma), and the mutation status of BRAF gene protein in above specimens were detected by polymerase chain reaction and DNA sequencing. Expression of Cyclin D1 and BRAF (V600E) mutation in papillary thyroid carcinoma and their correlation clinicopathologic features were also analyzed. Results The positive rate of Cyclin D1 in 88 cases of PTC was 84. 6%,and the immunoreactivity score (4. 6 ± 2. 4), compared with thyroid be-nign lesions (1. 3 ± 1. 6), was statistically significant difference (t=8. 525, P<0. 01). Expression of Cyclin D1 was closely related with lymph node metastasis, capsular invasion, tumor stage Ⅲ+Ⅳ and BRAF (V600E) mutation (P<0. 05), but not related with age, gender, number and diameter of tumor nodules. In 52 cases of PTC BRAF gene mutation rate was 63. 5%, but in thyroid benign lesions mutation rate was 0, with significant difference (P<0. 01). The BRAF mutation is closely related with lymph node metastasis, capsular invasion and tumor stage Ⅲ+Ⅳ(P<0. 05), but not related with age, gender, number and diameter of tumor nodules. The expression of Cyclin D1 in BRAF (V600E) mutation group was stronger, the positive expression rate was significantly higher than that of wild group (100% vs 57. 9%), and expression of the mean score was higher than that of the wild group (5. 7 ± 1. 6 vs 4. 0 ± 2. 5);the comparison between the two groups showed statistical difference (t=2. 652, P<0. 05). Conclusions The expression of Cyclin D1 and BRAF (V600E) mutation are positively related, which are also closely related with the occurrence and development of PTC, and can be used as an index to predict the invasion and metastasis in PTC.

The development of gastrointestinal minimally invasive surgery in China is changing during the past decade.The Chinese laparoscopic gastrointestinal surgery study (CLASS) group as the earliest and most closely cooperated organization for surgical clinical researches,under the support of Chinese Medical Association,Chinese Anti-cancer Association and Chinese Medical Doctor Association,the clinical research capacity and minimally invasive technology of the CLASS group continue to be developed.With the launch of the prospective,randomized,controlled CLASS-01 trial for the treatment of locally advanced gastric cancer in 2012 and the publication of safety results of laparoscopic surgery for gastric cancer in 2016,the international academic community is increasingly focusing its attention on China.This article attempts to review the history and development of the CLASS group in the past 7 years,aiming to prospect the future and attempt to create trends.

Objective To explore the application ways of IHE XDS technology in electronic medical record (EMR) system and develop application system of clinical EMR integration. Methods The clinical EMR integration plan was worked out based on IHE XDS technical framework. Results A EMR solution based on IHE XDS was presented. It was consisted of the components of the clinical Data Entry, XDS Registry, clinical document Repository, EMR application server and the i-node accessing server. The system was tested and the result indicated that the system was effective and scalable. Conclusion IHE XDS profile can be not only used to realize the sharing of EMR documents across multiple hospital, but also support the collection clinical data within a hospital clinical system integration.

Chinese donation after citizen's death (CDCD) is an important way to solve the donor shortage problem,but if we can't effectively control warm ischemia time of CDCD donor,it's easy to cause grafts primary nonfunction,early grafts dysfunction and biliary complications.Nowadays,with the development of surgical techniques,the definition of warm ischemia continues has been continuously updated.The understanding on different definitions may lay the foundation for improving the survival rate of liver and kidney and effectively protect liver and kidney function after transplantation.This paper overviewed the significance of different definitions of warm ischemia and its effect on liver and renal function,which could provide a reference for further experimental study and clinical practice.

BACKGROUND:Rehabilitation brace can significantly improve the motor function of patients with post-stroke hemiplegia. OBJECTIVE:To investigate the types and biocompatibility of brace materials for post-stroke hemiplegia. METHODS: A computer-based search of Wanfang, CNKI, PubMed databases was performed for articles related to post-stroke hemiplegia and biocompatibility of brace materials published from 1999 to 2015 using the keywords of cerebral apoplexy, hemiplegia, support, material in Chinese and English, respectively. In the same field, the articles published recently or in authoritative journals were preferred. Finaly, 15 articles were enroled in result analysis. RESULTS AND CONCLUSION: Thermoplastic orthoses are mainly made of polypropylene materials, which are used for foot drop caused by post-stroke hemiplegia. Polypropylene has high strength and good toughness, and it is also safe and non-toxic. Semi-rigid planta pedis can help the lift of the toe in swing phase. Orthoses made of polymer fiber materials are characterized by ease of use, good toughness, high strength, and good air permeability, which cannot impact X-ray examination. Carbon fiber materials have light mass, high specific strength and modulus, good anti-fatigue performance, good safety performance and good designability. Clinical trials have shown that patients wearing ankle foot orthoses made of polypropylene and carbon fiber materials have improvement in walking distance and speed of climbing stairs, and these patients also feel more balanced and secure. Experimental studies on different orthotics materials can get more patient preferences, which have a great help for the design and development of orthotics materials.
