1.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.
2.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.
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 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.
7.Research progress of B vitamins and diabetic nephropathy
Clinical Medicine of China 2016;32(9):855-858
Diabetic nephropathy( DN) is one of the main manifestations of diabetic microvascular dis?ease,and it is a major factor in the death of diabetes.At present,the treatment of DN is mainly focused on the control of high blood sugar and high blood pressure.Although angiotensin converting enzyme inhibitors and angio?tensin II receptor antagonists can slow the progression of DN,there were a lot of patients deteriorate to renal fail?ure.The role of vitamin B supplementation in preventing microvascular complications of diabetes has already been a focus of research for some years.In this paper,the role of B vitamins in the pathogenesis of diabetes mellitus and DN,effect of vitamin B supplementation on treatment in DN were discussed.
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.

10.ROENTGEN MANIFESTATIONS OF RADIATION INJURIES OF BONES:A CLINICAL AND RADIOLOGIC ANALYSIS OF 17 CASES
Medical Journal of Chinese People's Liberation Army 1981;0(04):-
Based on a clinical and radiological study of radiation injuries of the bones in the 17 cases, the relationship between the osseous changes and the radiation dosage and between the time from radiation therapy and the onset of the radiographic osseous changes were discussed. The authors found that the degree of local skin infection might determine the type of its underneath osseous injuries, i. e. being either "septic" (osteomyelitic) or "aseptic" (bone atrophic) radionecrosis, and it might also determine the time when the osseous changes appeared on the radiogram. It was found that radiation injuries of the bone could be distinguished from bone metastases. The authors suggest that a regular X-ray follow-up of the bones that had received a heavy dose of radiation should be made in order to reveal bone atrophy as early as posible and to remind the patient to avoid any trauma and infection.
