1.Expression and clinical significance of stromal cell-derived factor-1 and its receptor CXCR4 in leukemia
Journal of Leukemia & Lymphoma 2009;18(1):57-59
Stromal cell-derived factor-1(SDF-1)is an early cell growth factor which belongs to a subfamily of chemokines.The CXCR4 is SDF-1 receptor.The SDF-1 interacting with CXCR4 plays important roles in physiological and pathological processes such as hematopiesis, stem cell homing,angiogenesis and leukemic cells infiltrating.To study the expression of CXCR4 in leukemia and the relationship between CXCR4 and leukemic cells infiltration can add indicators for leukemic MIC diagnosis of immunology indexes and have great significance to take molecule targeted therapy for preventing leukemia from infiltration or relapse as well.

7.Preventive and therapeutic effects of micronutrients on diabetes mellitus
Chinese Journal of Clinical Nutrition 2011;19(3):204-207
Micronutrients are closely associated with the progression of diabetes and its complications. Diabetic patients are susceptible to micronutrient deficiency. In this article, we summarize the preventive and therapeutic effects of micronutrients including zinc, selenium, magnesium, and chromium on diabetes mellitus.
8.Effect of combined use of aminoguanidine and cyclosporine A on acute rejection following cardiac allograft in rats
Chinese Journal of Organ Transplantation 2001;22(2):85-87
Objective To study the effect of the combined use of aminoguanidine (AG) and cyclosporine A (CsA) on acute rejection following cardiac allograft. Methods Except the control group, all other three groups were respectively treated by AG 600mg/kg every day subcutaneously 0 to 7 days after transplantation, low-dose CsA 2mg/kg every day i.m 0 to 7 days after transplantation, and low-dose CsA plus AG. Inducible nitric oxide synthase (iNOS) expression and nitric oxide (NO) production during acute allograft rejection were detected at 4th day after operation, and the graft survival was observed.Results Compared with the control group, iNOS expression and NO production were significantly inhibited in the AG-treated group (P<0.05),the progression of acute rejection was slightly attenuated and allografted heart survival prolonged. The inhibitory effects of iNOS activity and NO production in the recipients receiving the combined treatment of low-dose CsA plus AG were higher than those receiving low-dose CsA alone. Compared with the low-dose CsA group, low-dose CsA plus AG could significantly reduce the histologic grade of acute rejection (P<0.01) and prolong the graft survival (P<0.05). Conclusion The combined use of low-dose CsA and AG could synergistically suppress iNOS activity and NO production, and significantly prolong allografted heart survival.
9.Endoscopic diagnosis and treatment of malignant obstructive jaundice
Chinese Journal of Hepatobiliary Surgery 2011;17(10):865-870
Malignant obstructive jaundice is biliary obstruction caused by malignant tumors.When a patient presents to a doctor,he/she is usually too late to be operated,so endoscopic treatment has gradually replaced surgery in its management.Diagnostic endoscopic methods include endoscopic retrograde cholangiopancreatography (ERCP),endoscopic ultrasonography (EUS),and per oral cholangioscopy (POCS),etc.Biliary stent placement at ERCP is the mainstay of endoscopic palliation for jaundice.Other methods include EUS-guided bilioenteric drainage (EGBD),endoscopic radiofrequency ablation,intraluminal brachytherapy of bile duct,endoscopic photodynamic therapy,etc.Magnetic Compression Anastomosis Technique (MCAT) is a new technology which has been developed recently,and its role in the management of malignant obstructive jaundice remains to be seen.Science and technology have brought along progress in endoscopic and consumable technologies.It is predicted that in the future,endoscopic diagnosis and treatment will have more applications.
10.The management of patent ductus arteriosus in premature infants
Chinese Pediatric Emergency Medicine 2011;18(4):303-306
Patent ductus arteriosus (PDA)is a common disease among premature neonates and the management of which has always been a challenge to the neonatologists. Early treatment has been advocated as the first-line approach, and drug induced closure is yet the most effective, inexpensive, and convenient method. During the last two decades,indomethacin was often given as conservative treatment, and its closure rate in PDA was approximately 46% ~ 89%. However,indomethacin may increase the number of undesirable or harmful effects including renal damage, intraventricular hemorrhage, necrotizing enterocolitis, and enterobrosis,etc. Recently,ibuprofen is rapidly emerging as a new promising drug for treatment of PDA in preterm infants with closure rate of 73.0% ~95.5%. It is used as standard therapy to close PDA,and it has less influence on the hemodynamics of kidneys, brain and gastrointestinal tract. The surgery is needed in patients with drug treatment failure and cardio-pulmonary function damage.
