Objective To evaluate the recent impact and long-term effects of recombinant human acidic fibroblast growth factor (rh-aFGF) of cesarean section on women's abdominal incision healing.Methods In 516 cases of cesarean section in women,randomly divided into placebo group (172 cases),spray group (172 cases) and flush group (172 cases).The placebo group received 0.9% sodium chloride washing abdominal incision suture.The spray group incision suture direcdy after the administration of rh-aFGF spray,per square meter of 3-4 sprays,3-5 times/d.The flush group was given before 2 rh-aFGF dissolved in 10-20 ml of 0.9% sodium chloride directly after washing the incision suture,then given spray treatment.The recent follow-up of 15 d observed maternal abdominal incision healing.Long term follow-up of 3 months to observe the incision scar formation.Results The abdominal incision heating time was (8.6 ±3.5) d,that was obviously shorter than that in spray group (10.4 ±3.7) d and placebo group (12.7 ± 4.9) d (P < 0.05).The delay healing accounted for 4.2% (7/166) in flush group,significantly lower than that in placebo group (34/168,20.2%) and spray group (16/165,9.7%) (P< 0.05).There was no significant difference in the incidence of fat liquefaction,postoperative infection among three groups (P > 0.05).Flush group exudation,abdominal wall adhesions was lower than placebo group and spray group [2.4%(4/166) vs.10.1%(17/168),5.5%(9/165),3.6%(6/166) vs.17.3%(29/168),9.7%(16/165)](P<0.05).Long term follow-up,flush group scar area than spray group reduced by 13.5%,than placebo group reduced by 27.2%.Conclusions A recent rh-aFGF can reduce the cesarean section abdominal incision healing time and reduce abdominal wall adhesions and exudation;rh-aFGF the best dosage is intraoperative irrigation treatment spray combined with postoperative.
2.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.
3.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.
4.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.
5.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.
6.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.
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.

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.

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.
