2.Cytomegalovirus infection in systemic lupus erythematosus: an analysis of 121 cases
Chinese Journal of Rheumatology 2011;15(4):249-251
Objective To investigate the clinical manifestations of cytomegalovirus (CMV) infection in patients with systemic lupus erythematosus (SLE). Methods Data of the consecutive cases of SLE complicated with active CMV infection including clinical manifestations, SLEDAI score, dosage of corticosteroid and immunosuppressants used for treatment,radiological and laboratory examinations were collected and analyzed.Results Among 2221 consecutive patients of SLE, 5.4%(121 cases) were diagnosed to be complicated with active CMV infection. Fever was the most common symptom, followed by serious liver function damage,respiratory symptoms,hematological abnormalities, myocarditis, and encephalopathy, accounted for 81%(98cases), 6.6%(8 cases), 4.1%(5 cases), 3.3%(4 cases), 0.8%(1 case), and 0.8%(1 case)respectively; in addition, 22 (18.2%) cases had no symptom. SLEDAI was higher than 15 in 47.1% cases, and 10-14 in 28.1% cases. 81% of patients were treated with corticosteroid, and 55.4% were treated with immunosuppressants. Ganciclovir was given once the diagnosis of active CMV infection was established. In most of the patients, active CMV infection had been controlled within 14-28 days, except 4 died and 6 gave up the therapy. Conclusion SLE with active CMV infection is common,especially in patients who are treated with corticosteroid and/or immunosuppressants. Clinical manifestations of SLE complicated with active CMV infection are generally nonspecific.In patients with unexplained fever,or liver damage,or lung disease,or active SLE patients who have no symptom but are refractory to the treatment, CMV infection should be suspected and the relevant laboratory tests should be ordered for early diagnosis and treatment.
3.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.
4.The expression of CXCR7 in osteosarcoma tissues and cells
Journal of Chinese Physician 2010;12(8):1048-1051
Objective To study the differences of CXCR7 expression between in osteosarcoma tissues and normal peri-osteosarcoma tissues, and observe the effect on cell proliferation and inflammatory cytokine PGE2 secretion in MG63 cells when it had been transfected with pEGFP-Adv-CXCR7 vector. Methods CXCR7 expression in osteosarcoma tissues, cells and normal peri-osteosarcoma tissues detected by RT-qPCR. The CXCR7 mRNA expression, cell proliferation and PGE2 secretion of MG63 cells after transfected with pEGFP-Adv-CXCR7 expression vector were evaluated by RT-qPCR, MTT and ELISA, respectively. Results The expression rate and quality of CXCR7 mRNA in osteosarcoma tissue were 93.80% and (2. 221 ±0. 112), which significantly higher than those of normal peri-osteosarcoma tissues 45.71% and (0. 3448 ±0.098). Low expression of CXCR7 in MG63 cells was also observed. The proliferation and PGE2 secretion of MG63 cells were significantly increased at the time point of 48, 72 and 96h after pEGFPAdv-CXCR7 expression vector transfected into MG63 cells ( P < 0. 05). Conclusion The expression of CXCR7 mRNA in osteosarcoma tissues were significantly higher than normal peri-osteosarcoma tissues. CXCR7 high expression may have a negative effect on the progress of osteosarcoma.
5.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.
7.Pulmonary Hypertension Complication Pregnancy : Analysis of 10 Cases
Journal of Practical Obstetrics and Gynecology 2010;26(4):268-271
Objective:To analysis the clinical characteristics of pulmonary hypertension (PH) complicating pregnancy, then to explore the delivery time and the monitodng as well as the treatment during perinatal peri-od.Methods:The data of 10 cases with PH treated in our hospital from June 2005 to January 2009 were retro-spectively analyzed.Reaults:1 case was primary pulmonary hypertension(PPH) ; 9 cases were secondary PH (SPH), in which 4 cases were rheumatic heart disease and 5 cases were congenital heart diseases.3 cases were slight PH,6 cases were moderate PH, and 1 were severe group.4 cases NYHA class were Ⅰ~Ⅱ and 6 cases NYHA class were Ⅲ~Ⅳ.4 cases were term delivery,5 cases were premature delivery, and 1 got artifi-cial abortion.8 cases were cesarean section, and 1 was vaginal delivery.2 cases were very low birth weight infants, 1 infant was death and 1 mother was death.Conclusions:The patient of PPH should avoid concei-ving.For SPH patients whether to conceive depends on cardiac function, the level of pulmonary arterial pres-sure and should better get pregnancy after surgery or medication.It should terminate pregnancy in the first tri-mester for moderate or severe patients.Cesarean section is more suitable for those in the second or third tri-mester.The prognosis of the mother and neonate depends on several factors.
8.The curative effects of triplex surgical treatment on rectum prolapse
Clinical Medicine of China 2011;27(6):635-636
Objective To observe the effect of triplex surgical treatment, including rectal mucosa ligation,Xiaozhiling injection,encircing fighting surgery of the anus ring,on complete rectum prolapse. Methods From February 2007 to February 2010,fifteen cases with complete rectum prolapse were enrolled into this study and accepted triplex surgical treatment All patients were followed up for 1-4 years. Results The curative rate of the triplex surgical treatment was 100% with no serious complications. Conclusion Triplex surgical treatment was a simple, effective and reliable method in treating complete rectum prolapse, with less pain,fewer complications and quicker recovery.
9.Role of uric acid in fructose-induced metabolic syndrome
Basic & Clinical Medicine 2017;37(7):1059-1063
Excessive fructose intake can induce metabolic syndrome and increase serum uric acid levels.Uric acid levels are high in types of fructose-induced metabolic syndrome and may play a pathogenic role in the progression of these diseases.In this review,we focus on the role of uric acid in fructose-induced metabolic syndromes.
10.Advances of epigenetics in the progression of renal fibrogenesis
International Journal of Pediatrics 2014;(5):538-541
Epigenetics, which is called second genetic code precisely and controls the total metabolic processes of eukaryotic cells,has an inseparable correlation with human health and diseases. Among all the gene silencing mechanisms of epigenetic modifications,CpG islands of DNA promoter hypermethylation/histone mod-ifications are two major causes. Promoter methylation of specific genes,such as Ras protein activator analogue 1 may lead to aberrant activation of downstream signaling pathways,following by fibroblasts proliferation and kid-ney fibrosis. In recent years,epigenetic modifications have been proved to play a major role in preventing fibro-blasts to return to their quiescent stage,ultimately contributing to fibrosis in the kidney. This paper provides a glimpse of recent studies on epigenetic mechanisms of chronic kidney diseases,especially renal fibrosis,with an aim to provide new insights into pathogenesis research and clinical diagnosis and treatment.
