1.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.
2.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.
3.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.
4.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.
5.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.
6.Research progress of neonatal hypoglycemia and brain injury
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.
7.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.
8.Study on extraction of effective components in scutellaria baicalensis Georgi by orthogonal test
International Journal of Traditional Chinese Medicine 2015;(2):157-160
Objective To investigate the optimum extraction of total flavonoids and baicalin in baical skullcap root. Methods Ultraviolet spectrophotometry was used to detect the content of total flavonoids, HPLC was used to detect the content of baicalin. With the test of extracting method, time, frequency, and adding water volume, the optimum extracting craft was determined. Results The best craft for extraction was:heating water for recirculation, setting extracting time for 1.5 h, extracting frequency for 3 times, and water volume for 8 times of baical skullcap root. Conclusion The optimized process for extraction are stable, reasonable and feasible.
9.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.
