Chinese Journal of Applied Clinical Pediatrics 2014;29(12):948-950
Neonatal hypoglycemia is a common clinical disease.Hypoglycemia can lead to severe acute and long-term dysfunction of nervous system.The several aspects of neonatal hypoglyccmia such as the definition,diagnosis of brain injury,risk factors,treatment,detection method and long-term follow-up were reviewed.
2.Pancreas transplantation for diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 2012;28(1):85-88
Diabetes mellitus impacts patient survival and quality of life mainly due to its acute and chronic complications.Pancreas transplantation may restore normoglycemia and reduce the complication of insulin-dependent diabetes,thus improving the quality of life and prolonging patient's survival.Although pancreas transplantation requires major surgery and life-long immunosuppression therapy,it currently remains the gold stand for patients with type 1 diabetes mellitus,who do not respond to conventional therapy.Meanwhile,potential of the islet transplantation,insulin-producing cells replacement therapy,and artificial pancreas as the alternative to pancreas transplantation are under investigation.
3.Medical humanistic education from the view of recognition between teachers and students
Chinese Journal of Medical Education Research 2013;(8):777-781
Objective To observe the cognitional differences between teachers and students concerning teaching objective,curriculum,teaching methods and effect and teaching reform and to pro-vide references for teaching reform. Methods Medical humanistic questionnaire was designed to survey teachers and students. Data were processed by SPSS 18.0 and were analyzed by Chi-square. P value smaller than 0.05 signifies significant differences. Results There were significant differences in cognition of medical humanistic ability,emotion controlling ability,curriculuma provision and teaching methods between teachers and students.12.9% teachers and 41.3% students considered that the opportunity of medical humanistic practice was plenty while 55.7%teachers and 35.3%students thought that the univer-sity attached little importance to medical humanistic teaching. Conclusions Key points of humanistic reform include making clear the teaching objectives,emphasizing practice of medical humanistic teach-ing,improving curriculum and deepening appraisal reform.
4.Metabolism of amino acids and type 2 diabetes mellitus
Chinese Journal of Endocrinology and Metabolism 2012;28(9):773-776
Amino acids (AA) as substrates of gluconeogenesis could promote endogenous glucose production.Some AA can enhance insulin secretion. Recently,many studies have found that some AA can also activate mammalian target of rapamycin-S6 kinase 1 ( mTOR-S6K1 ) pathway,resulting in maintaining pancreatic β cell function on one hand,and on the other hand,inhibiting insulin signal transduction of insulin-sensitive cells and thus causing insulin resistance.
5.Research progress of neural stem cell source
Chinese Journal of Tissue Engineering Research 2009;13(27):5367-5370
Neural stem cells are a study hot spot in neurobiological science and neurosurgery in the near future. The transplantation of neural stem cells already became a new way which be used for treating the injury and degenerative disease in the nervous system, because of the self-renewal and cell differentiation bionomics. However, how to get massive neural stem cells, which can be used in animal experiment and clinical application, has constrainted the development of stem cell technique.This article introduced the harvesting methods of embryonic stem cells, adult neural stem cells and mesenchymal stem cells, in order to lead cellular transplant treatment into clinical treatment plan by a safe and effective mode.
6.Effect of process inspection on the selection and confirmation of coronary stents tubing
Chinese Journal of Tissue Engineering Research 2008;12(19):3796-3798
Based on concerns during stents manufacturing, the tubing purchase specifications of coronary stents have been proposed, and the key role of process inspection for judging the qualified tubing have been justified. By comparing the incoming inspection and the process inspection, it is concluded that the process inspection, as basis for optimizing tubing, is indispensable for selecting and confirming the tubing.
7.Recent advances in the study of G protein-coupled receptor 40/free fatty acid receptor 1
Chinese Journal of Pathophysiology 1986;0(02):-
Free fatty acids(FFAs) provide an important energy source and also act as signaling molecules.Medium to long-chain free fatty acids can activate the intracellular signal pathways in the pancreatic ?-cells and play a role in regulating insulin secretion as an extracellular signal molecular via binding to the FFA receptor G protein-coupled receptor 40(GPR40). Furthermore,GPR40 is associated with several biological effects including cell proliferation and antiapoptosis of nerve cells.GPR40 act an important role in the connection of obesity and diabetes or cancers.GPR40 will probably become a novel kind of antidiabetic and anticancer drugs.
8.Protective effect of Cordyceps Sinensis, Epimedium and Astragalus Membranaccus on gentamycin induced nephrotoxicity in rat
Chinese Journal of Pathophysiology 1989;0(06):-
Animal model of aged rat nephrotoxicity was induced by i. p. administrationof gentamycin in a dose of 140mg/kg/day. Part of those rats were treated with CordycepsSinensis(CS), Epimedium(Ep) and Astragalus Membranaccus (AM) in form of decoc-tion per Os and others seryed as control. The results were summarized as. 1. The nephro-toxicity of gentamycin was aggrevated with age. CS, Ep and AM are effective drugs inpreventing the tdeular damage caused by gentamycin in rats. The pathological changes ofrenal tuoules of the rat groups which treated with CS, Ep and AM were less severe thanthat of the control. 2. CS, Ep and AM could prevent the decline of renal cortical Na~+-K~+-ATPase activity of aged rat induced by gentamycin.
9.Protective effect of fentanyl on cultured cardiomyocyte against injury induced by anoxia-reoxygenation
Chinese Journal of Anesthesiology 1995;0(02):-
ve To assess the protective effect of fentanyl on primary cultured myocardial cells against injury induced by anoxia-reoxygenation. Methods Ventricular myocardial cells enzymatically isolated and cultured in 1640 culture medium for 6 days were randomly divided into 5 groups: group A received no anoxia served as control; group B received 2 hours anoxia followed by half an hour reoxygenation; and group C, D and E received 10ng ? ml-1, 30 ng ? ml-1 and 50 ng? ml-1 fentanyl respectively before anoxia-reoxygenation. The cell viability, myocardial intracellular content of malondialdehyde (MDA) and the activities of lactic dehydrogenase (LDH) and creatine kinase(CK) were measured at the end of the experiment. Results Anoxia-reoxygenation caused dramatic decrease in cell viability, and increases in myocardial intracellular MDA content and the LDH and CK activities as compared with those in control group. Fentanyl 30 ng?ml-1 and 50 ng?ml-1 significantly attenuated the increases in LDH, CK activities and MDA content, and decrease in cell viability caused by anoxia-reoxygenation. Fentanyl 10ng?ml-1 did not produce any significant changes. Conclusions Fentanyl can produce protective effects on primary cultured cardiomyocytes against anoxia-reoxygenation injury.
10.A novel drug coated stent and coronary restenosis
Journal of Medical Postgraduates 2003;0(11):-
The placement of stent in coronary artery reduces the restenosis rate of percutaneous transluminal coronary angioplasty(PTCA),but the restenosis has perplexed us so far. May be a novel drug coated stent will bring us a new hope in the coming years.
