This study was aimed to define the scope of traditional Chinese medicine (TCM) informatics standards. The basic construction of three-dimensional profiling framework includes TCM business domain, elements of TCM informationization and specificity level. The clinical informatics standards development was stated as an example to demonstrate the application method of this three-dimensional profiling framework.

Objective To transform knowledge organization systems (KOS) about traditional Chinese medicine (TCM) domain into standardized ontologies, in order to achieve the publication, sharing, and fusion of TCM KOS on the Web, and to further improve the organization and management of TCM knowledge. Methods Simple knowledge organization system (SKOS), a technical specification recommended by World Wide Web Consortium, was used to transform TCM KOS into publishable ontologies on the Web. Results Traditional Chinese medicine language system was transformed into an SKOS ontology, which was stored into a knowledge base that could support SPARQL (standard query language of the Semantic Web) query access, and provide concept, terminology, and knowledge services for Semantic Web applications, such as semantic wiki and semantic search via Web service interfaces. Conclusion This research preliminarily verifies the applicability of SKOS in TCM domain, and exemplifies the process of transforming TCM KOS into SKOS ontologies.

Human avian-origin influenza A (H7N9)virus is a novel subtype of avian influenza A virus,which firstly emerged at the end of March 2013 in Shanghai and Anhui province.It rapidly spread in China within a short time,causing high morbidity and mortality,arousing fear and panic in public,and attracting extensive attention worldwide.The analysis of human H7N9 avian influenza virus gene shows a high affinity for α-2,6-linked sialic acid receptors expressed on human respiratory epithelial cells.At present,the sporadic cases of human H7N9 avian influenza virusare occasionally reported with an epidemic peaksat winter and spring.This article reviews clinical features,epidemiology and genetic characteristics of H7N9 avian influenza virus,proving scientific evidences foreffective prevention and control of H7N9 virus infection.

This study analyzed the current clinical terminology standardization, systematization research status of traditional Chinese medicine(TCM). The previous version of the TCM clinical term system had some problems including imperfect classification structure, unclear relationship between concepts and so on, which made the TCM clinical terminology system(TCMCTS) difficult to support the clinical practice of TCM. The suggestions for system improvement were using ontology method to build TCMCTS concept model bases on the previous researches and data extracted from TCM clinical electronic medical record, and top-level-ontology accordance with ISO standards. The study also tried to summarize the ‘semantic network between classes’ through semantic relationships.

All elements and refinements had been built in ontology with protégé 4.1, which can be used to record over 20 classic Chinese medicine books in related author, publisher, storage site, edition, form and arrangement of lines in calligraphy, and etc. It also realized the graphical display based on ontology. It gave brief analysis on elements which had been used or without using. Studies showed that Web Ontology Language (OWL) can express all elements of TCM literatures clearly. This study indicated that element refinements should be considered to add in the amendment of ISO International Standards application for further improvement.

Objective To investigate the influence of Tanyu-Tongzhi (TYTZ)recipe on Rho/Rho kinase signal transduction pathway of myocardial ischemia-reperfusion injury in high fat-fed rats.Methods 60 SD rats were divided into 5 groups randomly,a sham-operated group,a model group,a western medicine control group,a high-dose group and a low-dose group of TYTZ recipe.The model of ischemia reperfusion of the myocardium was reproduced by ligation of left descending artery for 30 min followed by releasing the ligation for 2 hours in rats.The downstream substrates of ROCK myosin light chain (MLC) phosphorylation expression of myocardial tissues in rats were detected by Western blotting method.The levels of RhoA,ROCK Ⅱ mRNA were determined with RT-PCR.Results Compared with the model group,the expression of p-MLC and RhoA,ROCK Ⅱ mRNA were lower in low-dose group of TYTZ,there were significant differences between the two groups(P=0.004、0.003、0.018、0.004,P＜0.01).Conclusion The TYTZ Recipe can protect myocardium from MI/RI.The mechanism of action was related to its inhibiting the protein expression of RhoA,ROCK Ⅱ and p-MLC,restraining the activation of Rho/Rho kinase signal transduction pathway.

Aim Bupivacaine is a kind of long-acting amide local anesthetics.This paper aims to explore the effects of bupivacaine on the short-circuit currents in human alveolar epithelial monolayers and study the possible mechanisms.Methods Short-circuit currents were recorded by ussing-chamber setup.Amiloride-sensitive currents were defined as the difference be-tween the total current and the amiloride-resistant cur-rent.ERK1 /2 phosphorylation protein levels were ana-lyzed by Western blot at 0,1 5,30 and 60 min after administration of 1 00 μmol·L -1 bupivacaine.Results Bupivacaine could inhibit the short-circuit currents in H441 monolayers dose-dependently,which could be inhibited by amiloride.Western blot analysis showed that bupivacaine increased the level of ERK1 /2 phos-phorylation.Conclusion These data demonstrate that bupivacaine can reduce the alveolar ion transport by in-hibiting the amiloride-sensitive currents,possibly by the enhancement of ERK1 /2 phosphorylation. The effects of alveolar fluid clearance following application of bupivacaine should be considered clinically when the patient is complicated with lung injury.

Secondary immune response is an important endogenous mechanism of neurological injury after ischemic stroke.Spleen and interferon-γγplay an important role in it.Monitoring the spleen size and the level of interferon-γγhave an important reference significance for the severity of stroke and outcome assessment.

Objective To investigate the prevalence of depression and its risk factors in type 2 diabetes mellitus.Methods Beck Depression Inventory (BDI) was used to evaluate depression in 2 966 type 2 diabetes mellitus patients [ male 1 463,female 1 503,age ( 56.4 ± 11.2 ) years,diabetes duration ( 6.3 ± 5.7 ) years ].Depression criteria:≤4 points,no depression group; 5-13 points,mild depression group; 14-20 points,moderate depression group; 21 points or higher,severe depression group.Meanwhile,the demographic and metabolic data and diabetes-related health behaviors were also investigated.The risk factors associated with depression were screened by logistic regression.Results 51％ patients had depression,including 38％ with mild,8％ with moderate,and 5％ with severe depression.Compared with no depression group,depression was correlated with female sex,low-annual income,diabetes education,diabetes treatment,with insulin and peripheral neuropathy( P＜0.01 ).More smoking and younger age were found in severe depression( P＜0.05 ).Partial correlation analysis showed that depression in type 2 diabetes mellitus was positively correlated with female sex,diabetes education,and peripheral neuropathy ; and negatively correlated with age (P＜0.05).Conditional logistic regression equation showed that gender( OR =1.37 ),age ( 20-40 years,OR =1.52 ),diabetes education ( OR =1.51 ),and peripheral neuropathy ( OR =1.87 ) were risk factors for depression.Conclusion Depression is common in type 2 diabetes mellitus.More attention should be paid to screening depression in clinical practice.

Prediabetes is a glucose metabolism status between normal glucose metabolism and diabetes.It can not only increase the risks of occurrence and recurrence of stroke, but also affect stroke outcomes.Prediabetes causes ischemic stroke mainly through the insulin resistance and blood-brain barrier damage.Non-drug or drug intervention in patients with prediabetes can delay progression from prediabetes to diabetes and reduce the risks of occurrence and recurrence of stroke.
