1.Molecular mechanisms of angiogenesis after cerebral ischemia
International Journal of Cerebrovascular Diseases 2010;18(2):146-150
Angiogenesis is an important self-repair and remodeling mechanism after cerebral ischemia. It plays pivotal roles in promoting local blood circulation, protecting neurons and improving neurological function after cerebral ischemia. A variety of molecules and signal transduction pathways involved in the regulation of the process, including angiogenin, growth factors, matrix metalloproteinases, tissue kallikrein and anti-angiogenic proteins. This article reviews the roles of these molecules and signal transduction pathways in angiogenesis after cerebral ischemia.
2.Patent Foramen Ovale and Ischemic Stroke
International Journal of Cerebrovascular Diseases 2008;16(5):342-346
Despite detailed examinations have been performed,the etiology in about one third of ischemic strokes remain uncertain,which are called cryptogenic ischemic strokes.In the recent 2 decades,it has been found that patent foramen ovale(PFO)is closely associated with these cryptogenic strokes,and a roamber of profound studies have been performed subsequently,and a lot of new conceptions have been put forward.INs article reviews advances in research on the relationship between PFO and iscbemic stroke.influencing factors of PFO leading to ischemic stroke,as well as the diagnosis and treatment of PFO.
3.Study pediatric fundus imaging techniques to improve the diagnosis of retinal diseases in children
Chinese Journal of Ocular Fundus Diseases 2016;32(3):237-242
Fundus photograph,angiography,optical coherence tomography,ultrasonography and other image technology and visual electrophysiology can provide a wealth of information for the diagnosis and treatment of pediatric retinal diseases.However,it put forward higher requirements on pediatric retinal imaging equipment and techniques which will be quite different from adult,because of pediatric retinal disease has its own characteristics,such as disease spectrum,pathogenesis,and pathophysiology.The principles and methods of image results interpretation on adult were not quite ready for children.It is necessary to further study the fundus imaging techniques suitable for children,gradually establish standardized examination procedures and clinical interpretation system,to promote the diagnosis of retinopathy in children.
5.The quality of basic research in ophthalmology needs to be improved in China
Chinese Journal of Experimental Ophthalmology 2011;29(8):673-675
Basic research program is essential to the investigation of the pathogenesis of ocular diseases and the development of novel strategies for the prevention and treatment for these diseases. With increasing support of research grants at various levels, basic research in ophthalmology has gained great achievement in China in recent years. A number of studies have recently been published in well known peer-review international journals and won the State Scientific and Technological Progress Awards. However, we have to keep it in mind that basic research in ophthalmology should be improved qualitatively meanwhile, the imbalance in basic study among different areas needs to be resolved in the near future.

Objective To discuss the value of preoperative C-reactive protein (CRP) and eryth-rocyte sedimentation rate (ESR) in predicting postoperative infections following multiple fractures. Methods A study was conducted in 78 patients with multiple fractures (complicated with pelvic frac-ture, ISS > 18) treated in our department from December 2006 to March 2009. CRP and ESR levels be-fore second damage control operation as well as postoperative infections were recorded. Meanwhile, the optimal cut-off value was determined by receiver operating characteristic curve and analyzed. Results There were 11 patients with postoperative infection. The preoperative optimal cut-off value of CRP was 50 mg/L, with a sensitivity of 0.909 and a specificity of 0.821. The preoperative optimal cut-off value of ESR was 27.5 mm/h, with a sensitivity of 0.818 and a specificity of 0.791. The combination tests showed the sensitivity and specificity of 0.875 and 0.900 respectively. Conclusion CRP (50 mg/L) can be a sensitive predictive index for postoperative infection in the multiple fractures (complicated with pelvic fractures). Combination test of CRP and ESR can benefit diagnosis of postoperative infection.

Objective To evaluate the preoperative CT scanning in cardiac carcinoma.Methods 52 cases of cardiac carcinoma proved by operation and pathology were analysed.Results By CT scanning,the size of the tumor,it′s local extension and relation to the adjacent structures and lymph node metastases could be demonstrated.Conclusion CT scanning plays important role in the operability of the cardiac carcinoma and the planning of treatment.

Objective To study the association of the serum soluble intercellular adhesion molecule-1(SICAM-1) and soluble vascular cell adhesion molecule-1(SVCAM-1) with metabolic syndrome(MS) and its components. Methods The MS was defined by criteria of the international diabetes federation. The levels of SICAM-1 ,SVCAM-1,plasma glucose,insulin,lipids,uric acid, glycosylated haemoglobin A(1C), and blood viscosity were measured. Results The concentrations of SICAM-1 and SVCAM-1 were significantly higher in subjects with MS and its components than in those without them. The concentrations of SICAM-1 and SVCAM-1 were correlated positively with disorder number of BMI, WHR, SBP, DBP,FPG, 2 hour plasma glucose, triglyceride, uric acid, HbA1c, blood viscosity and HOMA-IR,and negatively with high density lipoprotein cholesterol. Conclusions The concentrations of SICAM-1 and SVCAM-1 rise with the increase of the number of MS components. Endothelial dysfunction might participate in the occurrence and development of MS.

Objective To investigate the correlation of serum ereatine kinase iseenzyme-MB (CK-MB) and recent cardiac events(30 days, 180 days) and late cardiac events (360 days) in patients with acute coronary syndrome (ACS). Methods Serum creatine kinase (CK) and CK-MB in 168 patients with ACS were measured, and these patients were divided into four groups according to the levels of CK and CK-MB. The occurrence of cardiac events analysis of CK and CK-MB was followed up for 30, 180 and 360 days and the relationship between the occurrence of cardiac events and the levels of CK and CK-MB were studied. Results There was statistical correlation between increased CK-MB and abnormal ECG Q wave, ST segment change (P< 0.05), 168 patients had followed up 30, 180 and 360 days, in which cardiac events happened in 57 common patients (64 examples), 27 examples (16.1%) happened in the recent cardiac event, and 37 examples(22.0%) happened in the late cardiac event. The cardiac event and CK-MB elevation had statistical correlation (P<0.05). Conclusion ACS patients with increased CK-MB levels prompt a poor prognosis, and could be an independent indicator of recent and late cardiac events in patients with ACS.
