Objective:To investigate the effect of cilostazol on erectile function in diabetic rat model.Methods:Diabetes were induced in 50 male adult sprague-dawley(SD) rats by an intraperitoneal injection of streptozotocin.The DM rats were randomly divided into diabetic group(DM group )and cilostazol therapy group(CI group) 8 weeks after the injection(another 10 normal SD rats as control,C group).The rats in each group were treated with cilostazol20 mg/(kg?d) or NS through a gastric perfusion for 8 weeks.Then the erectile function of all these rats was evaluated by apomorphine.Motor nerve conduction velocity of sciatic nerve(MNCV) was evaluated by electrophysiology method.Their penis tissues were harvested to measure the level of nitric oxide synthase(NOS) by colorimetric method,and the penile cell apoptosis of smooth muscle was analyzed by TUNEL assay.Results:The erectile function,MNCV and NOS level in CI group significantly increased,while the apoptosis ratio significantly decreased(P

Cytokine-induced killer cells (CIKs) are a kind of non-MHC restricted cytotoxic T cells that have been recognized as the best adoptive immunotherapy against tumor. Dendritic cells(DCs) play a pivotal role in the interaction between tumor cells and T cells. Coculture of CIKs and DCs enhances the proliferation rate and cytotoxicity of CIKs, and has been shown to have strong cancer killing effects in various organ sites.

Chimeric antigen receptor T lymphocyte immunological therapy (CAR-T)is a new oncologic immunotherapy in recent years,which has been widely used in patients with leukemia and lymphoma and achieved a certain effect.Neuroblastoma is one of the most common extracranial solid tumors in children and over 50％ of patients have metastatic recurrence when first diagnosed.The prognosis for the high-risk neuroblastoma remains poor at the moment and it's time to look for new treatments.In this review,we summarize the basic structure and development of CAR-T,discuss the principles and risks of CAR-T in the treatment of neuroblastoma,and give an outlook to CAR-T in the treatment of solid tumors.

Objective To investigate the change trend for D-dimer,antithrombin activity (AT:A),tissue plasminogen activator(t-PA),plasminogen activator inhibitor-1 (PAI-1)and yon Willebrand factor (vWF) before and after treatment in patients with cerebral infarction,so as to evaluate the clinical value of the above parameters in therapeutic effect monitoring of cerebral infarction.Methotis SYSMEX CA7000 blood coagulation analyzer was applied to determining plasma D-dimer,t-PA,PAI-1 and AT:A,and ELISA was adopted to measure vWF.Results Compared with those of healthy control group,D-dimer,PAI-1 and vWF were significantly increased (P<0.01),t-PA was significantly decreased (P<0.01),and AT:A had no change (P>0.05) in cerebral infarction group before treatment.In cerebral infarction group,compared with those of pre-treatment,D-dimer,PAI-1 and vWF were significantly decreased (P<0.01),t-PA was significantly increased(P<0.01),and AT:A had no change(P>0.05) after treatment.So was the situation between GCS>8 and GCS≤8group.Conclusion There are obvious changes of fibrinolytic system parameters and vWF level befor and after treatment in patients with cerebral infarction,and the changes are associated with the course of disease.

With the arrival of knowledge information age,the management of university scientific research is faced with the new opportunity as well as the challenge.This paper has made a brief analysis to the present situation of university scientific research management service,and discussed the way to improve the management level of university scientific research from aspects of humanist,overall development,coordinated development and sustainable development in the further study and practice the scientific concept of development activities,and discussed the way to improve the management of university scientific research.

Objective To study the effect of FK506 pretreatment on endotoxin shock induced by LPS. Methods 155 mice of the Kunming strain were randomly divided into LPS group (n=80) and LPS|FK group (n=75). An endotoxin shock model of mice was reproduced by an intraperitoneal injection of LPS (25ml/kg for each mouse). Beginning from 2 days before the reproduction of the model, each mouse of the LPS+FK group were given 20ml/kg of FK506 q 12 h, by gastric gavage while animals of the LPS group were given an equal amount of 0.9% sodium chloride solution in the same way. The survival time of 20 mice of the LPS group and 15 mice of LPS+FK group was observed. 10 mice of each group were sacrificed at 0,0.5,2,4,6 and 8 hours after the injection of LPS, respectively. Blood samples were collected and serum TNF-? and IL-1?, contents, and activiry of ALT and AST were determined. The ratio of the wet weight and dry weight (W/D) of the lung was calculated, and the histopathology of the lung and the liver was studied. Results The mean survival time was longer and the 72h survival rate in mice of LPS+FK group was higher, but the serum ALT and AST activity and serum TNF-? and IL-1? contents were lower than those of LPS group at each time point. The W/D ratio of the lung in animals of both groups at 4,6 and 8 hours after the injection of LPS was greater than that at 0 hour (P

Objective To explore the effects of Seretide(50/250 μg)in the treatment of patients with stable moderate COPD.Methods Sixty-four patients in the stable period of moderate COPD were randomized into 2 groups,the test group and control group.The control group received routine treatment.The test group received the Seretide(50/250 μg)inhalation in addition to the routine treatment.During the 2-year observation,the pulmonary functions before and 12 and 24 months after treatment were recorded.The clinical symptoms,physical signs,the frequency of acute exacerbation of COPD and hospitaliztion duration were also graded.Results The difference of the parameters before and after the treatment was significant in the treatment group(P ＜0.01)but not in control group(P ＞0.05).The scores of symptoms and signs([2.1 ±0.4]vs.[4.4 ± 0.3],t =2.365),the frequency of acute exacerbation of COPD(29％ vs.47％,x2 =3.547)and hospitalization period ([5.0 ± 1.2]d vs.[10.0 ± 1.6]d,t =2.149)in the treatment group were significantly improved compared with control group after 24 months' treatment(all P ＜ 0.01).Conclusion Seretide(50/250 μg)is able to improve the lung function of the patients with stable moderate COPD and reduce the frequency of acute exacerbation,showing certain value in clinical practice.

Objective To assess the status of self-esteem of college students of higher vocational medical school and to provide targeted guidance.Methods Totally 1014 college students of higher vocational medical school were assessed using self-esteem scale and the results were analyzed by SPSS 13.0.Results The self-esteem levels among different student levels were different.The self-esteem level was lower in students of technical secondary school than in students of vocational college and junior college.The self-esteem levels were different among factors of different grades,family location,duty and post,satisfaction degree for school,individual health and family education (P ＜ 0.05 ) ;while they are not significantly different among factors of gender,major,being singleton or not and family types ( P ＞ 0.05 ).Conclusions School should further strengthen the mental health education and use kinds of methods to improve the self-esteem of college students.
