2.Inhibition of Tumor Angiogenesis by Targeted Induction of Endothelial Cell Apoptosis
Journal of Sun Yat-sen University(Medical Sciences) 2017;38(2):204-214
Angiogenesis is one of the important pathological characteristics in the development of tumor growth. Hence ,an?ti-angiogenes is has become a hot topic in the field of cancer research. The current strategy for anti-angiogenesis therapy is to restore the angiogenic balance which is broken in the tumor via either block of proangiogenic factorsor application of angiogenic inhibitors. Endogenous angiogenic inhibitors show more promising prospects compared with proangiogenic factor antagonists. However ,the un?derlying mechanisms for the angiogenic inhibitors remain to be thoroughly elucidated. There are two kinds of endogenous angiogenic inhibitors,one is the hydrolyzed fragments of precursor protein,such as plasminogen Kringle 5(K5),angiostatin/kringle 1~4,end?ostatin,etc;the other is cell secreted proteins,such as pigment epithelium-derived factor(PEDF),kallikrein-binding protein (KBP/kallistatin),antithrombin,etc. Here we summarized the research progresses on the biological functions,underlying mecha?nisms of tumor angiogenesis and application prospects of K5,PEDF,and KBP,so as to provide insights into the antiangiogenic ther?apies of tumor in the future.

Objective:To explore the effect of Shenfu Injection (SFI) on expression of Heme oxygenase-1 (HO-1) and iNOS (inducible nitric oxide synthase) in renal failure rats induced by intestinal ischemia-reperfusion (IR) and its possible mechanism. Methods:The model of intestinal ischemia-reperfusion was induced by clamping superior mesenteric artery for one hour and then releasing the arterial clamp for six hours. Wistar rats were randomized into three groups:IR+normal saline group,IR+SFI group and control group (C group). The serum creatinine and blood urea nitrogen were observed respectively. Expression of HO-1 and iNOS in rat kidney tissue was detected by immunohistochemitry and morphometry computer image analysis. The histological change of kidney was observed under light microscope. Results:①Compared with C group,expression of HO-1 and iNOS increased markedly in IR+ normal saline group (P
4.The use of insulin detemir in pregnancy with diabetes mellitus
Chinese Journal of Diabetes 2015;(4):381-384
[Summary] Poorly controlled hyperglycemia is closely associated with adverse outcomes during pregnancy. As the prevalence of diabetes rapidly increases ,the management of diabetes during pregnancy has been a significant and urgent need in clinical practice. This article reviewed the hot spots in the research field of gestational diabetes mellitus (GDM ) and pregnancy with diabetes mellitus ,including progresses on the risk factors for GDM and the long term effects of diabetes during pregnancy on mothers and offspring. This was followed by a body of evidences on the clinical benefits of improved glycemic control during pregnancy ,current therapeutic strategy using insulin as the golden standard as well as the potential advantage of insulin determir due to its unique pharmacokinetic‐pharmacodynamic (PK‐PD ) profile in this therapeutic area. Finally ,the authors summarized data from clinical trials on the usage of insulin detemir in pregnancy and in particular went over the designs and results of two randomly controlled trials investigating the efficacy and safety of insulin detemir in pregnancy patients with T1DM. Currently available data proved that insulin detemir was effective in improving glycemic control with a good safety profile in diabetic pregnant patients ,which may serve as an ideal choice in the management of diabetes during pregnancy.
5.Efficacy of self-help interventions based on cognitive behavioural therapy on depression: a systematic review
Chinese Journal of Behavioral Medicine and Brain Science 2016;25(5):404-409
Cognitive behavior therapy (CBT) has been proved to be an effective psychological treatment method for depression,especially for mild-to-moderate depression,however,due to the influence of various factors,its application in patients with depression is limited.Studies abroad have confirmed self-help intervention based on CBT has good effects on patients with depression.By reviewing efficacy of self-help interventions based on CBT on depression,it can be known that most of the literatures support that self-help interventions based on CBT has good effects on depression.Related researches abroad have been more mature,but few similar studies have been conducted in our country.So self-help CBT for depression has broad prospects in our country,which can play an important role in the prevention and therapy of depression,alleviating the shortage of medical resources,and reducing the patients' medical expenses,etc.Based on bibliotherapy (a major form of self-help interventions based on CBT),future studies need to learn from foreign practice to expand the audience to the clinic,community and non-clinical patients,in order to provide advice for interventions for depression in China.
6.Changes of vascular endothelial growth factor and tumor necrosis factor-α levels in serum of patients with primary hepatocellur carcinoma
Chinese Journal of Primary Medicine and Pharmacy 2009;16(2):227-228
Objective To investigate vascular endothelial growth factor(VEGF) and TNF-α levels in the serum of patients with primary hepatocellur carcinoma(HCC),and to evaluate their relevance with the development and metastasis of HCC.Methods VEGF and TNF-α levels in serum were examined by enzyme linked immunosorbent assay(ELISA) technology in 87 patients with HCC and 10 healthy individuals.Results Serum VEGF and TNF-α,levels in HCC patients were significantly higher than that in the contorl group.In addition,HCC patients infected with hepatitis virus(including HBV and HCV) showed a remarkable elevation in serum VEGF and TNF-α levels.The VEGF and TNF-α levels in HCC with metastasis were also higher than those without metastasis.Conclusion The serum VEGF and TNF-α levels in HCC patients might serve as the pivotal biological indices that could reflect HCC progressien and metastasis.
7.Study on the mechanisms of T cell vaccination-induced survival prolongation of cardiac allograft in rats
Chinese Journal of Organ Transplantation 2000;21(5):303-305
Objective To investigate the effect of T cell vaccination(TCV)on the survival time of cardiac allograft in rat.Methods Rat heterotopic cardiac transplantation was performed,Donor antigenprimed recipients' spleen cells were obtained bv 1/3 splenectomy for the preparation of TCV.TCV was then intraperitoneally into the abdominal cavity again.The survival time of cardiac allograft was observed.Results TCV could markedly prolonged rat cardiac allograft survival.T cell proliferation was increased and B cell proliferation was not affected in the vaccinated rats.The mixed lymphocyte reaction(MLR)was inhibited,The analysis of phenotypes on T cells showed that the number of CD8+ clones in vaccine cells and vaccinated rat spleen cells were increased.The antibody-mediated cytotoxicity was not affected by TCV.Conclusions TCV enhances the recipients' T cell-mediated immune response.The TCV-induced hyporeactivity to specific donor antigen is related to the induction of anti-idiotypic response and is not associated with humoral mechanisms.

Chinese Journal of Digestive Endoscopy 2010;27(12):617-620
Objective To retrospectively study histopathologic features of ulcerous colitis (UC) and Crohn's disease (CD) by endoscopic biopsy. Methods Data of age, gender and intestinal involvement of 106 cases of CD and 180 cases of UC confirmed by pathology were reviewed. Mucosal architecture, chronic inflammation, acute inflammation and epithelial features were evaluated based on histopathological criteria.These features were compared between the two groups. Results Compared with CD cases, UC showed significantly higher percentage of architectural disorders ( P < 0. 05 ), lower percentage of discontinuous chronic inflammation ( P < 0. 05 ) and higher incidence of cryptitis, crypt abscesses and polymorph cells in lamina propria (P <0. 05 ), and higher rate of epithelium damage, flattened and less mucous cell as well. Granuloma, pseudo pylorus glands metaplasia and narrow ulcer only occurred in CD cases. Lesions of 90% (162/180) cases of UC were limited to colon, while those of 28% (30/106) of CD cases to ileocecum, and those of 56% (59/106) CD cases involved different parts of gastrointestinal tract. Conclusion Diagnosis of CD and UC needs comprehensive analysis. Diagnostic evidence for CD includes focal involvement of ileocecum, the multifocal involvement in gastrointestinal tract, granuloma, discontinuous inflammation, pyloric gland metaplasia, while that for UC includes mucosal damage limited to colon, continuous chronic inflammation, architectural disorders, or epithelial damage.
