1.Ischemic stroke subtype classification: a comparative study of ASCO, CISS and TOAST
International Journal of Cerebrovascular Diseases 2013;21(6):430-434
Objective To investigate the differences in the clinical application of the etiological subtypes of ischemic stroke according to the TOAST,ASCO and CISS criteria.Methods A total of 167 consecutive patients with fist-ever ischemic stroke were enrolled in the study.They were classified with the TOAST,ASCO and CISS criteria,respectively.The differences and consistency of subtype diagnosis of each etiology were compared.Results Compared with TOAST,ASCO grade 1 significantly increased the proportion of patients in a large atherosclerosis group (23.4% vs.19.8% ;x2 =4.167,P =0.031) and decreased that in a small vessel disease group (32.9% vs.38.3% ; x2 =4.923,P =0.022); similarly,CISS also significantly increased the proportion of patients in the large atherosclerosis group (37.1% vs.19.8% ;x2 =27.034,P <0.001)and decreased that in the small vessel disease group (19.2% vs.38.3%;x2=25.289,P < 0.001).However,ASCO grade 1 (34.1% vs.28.1%;x2 =3.682,P=0.052) and CISS (32.9% vs.28.1%;x2 =0.880,P =0.268) did not decrease the proportion of patients in a cryptogenic group.The consistency of the 3 typing methods was between moderate (other etiology group of TOAST/ASCO-1,κ =0.434) and excellent (cardioembolism group of TOAST/ASCO-1,κ =0.967).Conclusions Both ASCO-1 or CISS typing may not decrease the proportion of the patients with the subtype of cryptogenic stroke,but the consistency among all the subtypes was better.The design and characteristics of the diagnostic criteria in all subtypes with the 3 criteria should be considered in clinical practice.
2.Endothelial monocyte-activating polypeptide- Ⅱ and tumor
Journal of International Oncology 2011;38(11):819-822
Endothelial monocyte-activating polypeptide-Ⅱ (EMAP-Ⅱ ) is a novel proinflammatory cytokine with proinflammatory,proapoptotic and antiangiogenic properties.It is associated with many tumorassociated proteins,such as tumor necrosis factor,vascular endothelial growth factor,hypoxia inducible factor-1α,arginyl-tRNA synthetase,and insulin-like growth factor- Ⅰ.EMAP-Ⅱ has anti-tumor properties and has a good prospect in cancer prevention and treatment.

Bacillus anthracis , the aetiological agent of anthrax, was the first discovered pathogenic bacterium in history Rapid progresses have been made on this field in recent years, especially; Bacillus anthracis has been sequenced successesfully early this year and published on the Internet The anthrax pathogenesis is always central to the study and there has been an enormous amount of work to elucidate it In this review, we will focus on the latest findings that concern three aspects of anthrax pathogenesis: Bacillus anthracis genome, pathogenic substances and pathogenesis mechanism
4.Advances on DNA methylation for noninvasive tumor molecular diagnosis
China Oncology 2001;0(03):-
DNA methylation is one of the most common epigenetic events in eukaryotic cell.Aberrant DNA methylation is tightly related to tumorigenesis.Recent evidence indicates that DNA methylation is a promosing biomarker for cancer.The cancer-associated DNA methylation events could be detected from serum(plasma),urine,stool and bronchoalveolar lavage,providing a new choice for noninvasive cancer diagnosis.In this review,we summarized the advances on DNA methylation for noninvasive cancer diagnosis.
7.Immunomodulatory features of chemotherapeutics
Journal of Medical Postgraduates 2004;0(01):-
Chemotherapeutic drugs conventionally used for their cytotoxic activity can also exert their influence on the immune system by grooming the tumor microenvironment,abrogating immune tolerance and inciting immune reconstitution.Due to their immunomodulatory features,chemotherapeutics,used as a preconditioning regimen and combined with subsequent immunotherapy,can mobilize the immune system to generate antitumor immune response.The synergy between chemotherapy and immunotherapy has brought some enlightenment to the development of new protocols for cancer treatment.
8.Clinical Application of Autofluorescence Imaging for Diagnosis of Gastrointestinal Neoplasms
Chinese Journal of Gastroenterology 2014;(9):570-572
Early diagnosis and treatment can improve the outcomes of patients with gastrointestinal neoplasms. Although digestive endoscopy is considered as a best method to diagnose gastrointestinal neoplasms,some early stage,flat-type neoplasms may be overlooked by routine endoscopy. In recent years,endoscopic autofluorescence imaging( AFI)as a new technique, has been widely applied in clinical practice for enhancing the endoscopic diagnostic accuracy of gastrointestinal neoplasms,especially for early stage,flat-type neoplasms. This article reviewed the clinical application of AFI for diagnosis of gastrointestinal neoplasms.
9.Construction of knowledge service system for university students'innovation and undertaking training program
Chinese Journal of Medical Library and Information Science 2015;24(12):38-41
Construction of knowledge service system for university students'innovation and undertaking training program was proposed by analyzing their difficulties in information access during innovation and undertaking train-ing.The key points in constructing knowledge service system were pointed out, namely establishing professional service teams, providing stereoscopic and diversified service, establishing feedback and evaluation systems, and building powerful platform for information exchange.
