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.
3.The effect of non-medical factors on the quality of life in maintenance peritoneal dialysis patients
Chinese Journal of Postgraduates of Medicine 2009;32(28):16-19
Objective To evaluate the quality of life (QOL) in continuous ambulatory peritoneal dialysis (CAPD) patients and analyze the non-medical factors influencing QOL in order to explore the possible way to improve QOL in peritoneal dialysis (PD) patients.Methods Seventy-nine chronic renal failure patients treated with PD included in the present study.Investigated their age,sex,working status,education,medical burden and family support.Patients' QOL was evaluated by international questionnaire-KDQOL/SF-36.Patients' anxiety/depmssion status was evaluated by Hamilton depression questionnaire.Results (1)The SF-36 with its eight scales of CAPD patients were markedly lower than ordinary people (P<0.05 or<0.01).(2) Comparing with those on work,the patients without work got lower SF-36 scores[(45.78±16.93) seores vs (32.65±12.26) scores,P<0.05].Comparing with those who had medical care,the patients without medical care got much lower SF-36 scores [(49.62±13.20) scores vs (33.85±6.24) scores,P<0.05].Patients with higher income had better QOL.(3) Patients cared by their children and companion had the higheat SF-36 [(68.33±14.73) scores],while those cared by nursemaid or themselves had the lowest [(27.98±15.77) scores].(4) Among the 79 patients,43 patients (54.4%) were anxiety and 12 patients (15.2%) were depression.QOL was negatively correlated with anxiety index and depression index.Conclusion The QOL of CAPD patients are remarkably low,which is deeply influenced by many non-medical factors such as working status,medical burden,family support and emotional status.
4.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.
5.Glucagon-like peptide-1 receptor agonists, diabetes, obesity, and psoriasis
Chinese Journal of Endocrinology and Metabolism 2012;28(4):255-257
More and more extrapancreatic actions of incretin-based therapies have been demonstrated and recently case reports have linked glucagon-like peptide-1 (GLP-1) receptor agouist therapy with the improvements in psoriasis.Psoriasis is a common skin disorder characterized by chronic inflammation.Epideminological studies have showed that patients with psoriasis exhibit increased rates of cardiovascular disease,obesity,and type 2 diabetes,owing probably to the enhanced local and (or) systemic inflammation.The observations of anti-inflammatory actions of GLP-1,which exerts direct and indirect actions on immune function,together with the improved psoriasis,offer new insights into the investigation of non-classical anti-inflammatory actions of incretin-based therapeutics and provide a new direction for the research of the novel clinical application of GLP-1.
6.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.

Chinese Health Economics 2017;36(6):71-73
Objective:To analyze whether medical insurance and environment protective behaviors could alleviate the influence of environmental pollutions on individual health status.Methods:Using the data of CGSS(2010) to conduct the empirical analysis based on Logit model.Results:Residents' choice on medical insurance and environment protective behaviors could alleviate the damage of environmental pollutions on health.Compared with the young and middle-aged,the elderly effectively alleviated the damage brought by environment pollutions through participating medical insurance.Compared with the low-educated individuals the high-educated inviduals' choices for environment protective behavior could effec tively release the damages brought by environmental pollutions.Conclusion:The government should advocate environmental protective behaviors,provide full coverage of medical insurances to let individuals alleviate the damages of environmental pollutions by their rational choice.More emphasis should be paid to the damage of environmental pollutions on the elderly group and individuals with lower education.
8.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.

10.A new NK-like cell subset of IL-22 producer:NK-22 cells
Chinese Journal of Immunology 2001;0(10):-
The mucosal tissues form the interface between the outside world and the sterile environment of the body.Innate immunity plays a critical role in the maintenance of mucosal homeostasis.Recently,a new subset of innate immune cells named NK-22 has been discovered to reside at tonsil and intestine both in human and mice.NK-22 cells share features with both natural killer (NK) cells and lymphoid tissue-inducing (LTi) cells.NK-22 cells express a variety of NK cell receptors and phenotypically resemble that of immature NK cells (iNKs).However,they are quite different from NK cells in function and development.NK-22 cells lack conventional NK cell cytotoxic function and produce IL-22 instead of IFN-?.It is currently considered that NK-22 cells are not a subset of NK cells.They develop from LTi cells and the development process depends on ROR?t and commensal microflora.NK-22 cells are involved in immune protection against the pathogen Citrobacter rodentium.The IL-22 secreted by NK-22 cells contributes to epithelial cell resistance to injury and mucosal tissue repair after microbial infection.
