OBJECTIVETo investigate the penile erectile function of hospitalized male patients with cardiovascular diseases, the incidence of erectile dysfunction (ED) in this cohort, and the relationship of ED with cardiovascular diseases and its risk factors.

METHODSUsing a self-designed questionnaire, we conducted an investigation among the hospitalized patients in the Department of Cardiovascular Diseases of the First and Second Affiliated Hospitals of Xi'an Jiaotong University. We measured their body height, body mass index (BMI), waist circumference, hip circumference, and blood pressure, obtained their personal data, past history, metabolic indexes, and erectile function scores by IIEF-5, and analyzed the risk factors of ED using univariate and multivariate logistic regression and OR analyses.

RESULTSTotally, 225 valid questionnaires were included in this investigation, which showed a 66.7% incidence of ED, 15.8% mild, 27.0% mild to moderate, 17.6% moderate, and 6.3% severe. The incident rates of ED in the 18-35 yr, 36-49 yr, 50-65 yr, and > 65 yr age groups were 13.6%, 39.1%, 89.2%, and 91.2%, respectively. Univariate logistic regression analysis manifested that the risk factors of ED in the patients with cardiovascular diseases included age (OR = 3.122, 95% CI 2.040-4.779), smoking (OR = 1.768, 95% CI 1.209-2.584), BMI (OR = 1.261, 95% CI 1.114-1.427), total cholesterol (OR = 1.77, 95% CI 1.339-2.340), TC/HDL (OR =1.715, 95% CI 1.349-2.181), hypertension (OR = 1.717, 95% CI 1.110-2.658), and coronary heart disease (OR = 2.235, 95% CI 1.169-4.275), while multivariate logistic regression analysis showed the risk factors to be age (OR = 4.99, 95% CI 2.264-10.998), financial condition, (OR = 2.804, 95% CI 1.127-6.976), smoking (OR = 2.109, 95% CI 1.179-3.772), BMI (OR = 1.414, 95% CI 1.136-1.760), and TC/HDL (OR = 2.001, 95% CI 1.016-3.943).

CONCLUSIONThe incidence of ED is high in hospitalized patients with cardiovascular diseases and rises with the increase of age. Age, smoking, financial condition, BMI, and TC/HDL are the risk factors of both ED and cardiovascular diseases, and financial condition is closely associated with ED.

Objective To elucidate the delayed neuron death and the expression of ?-amyloid protein (A?) in hippocampus after reperfusion of transiently ischemic lesion.Methods Immunohistochemical and HE technique was used to examine the delayed neuron death and expression of ?-amyloid protein at 6 h,2 d,3 d,7 d,14 d,35 d after reperfusion of transiently incomplete forebrain ischemia in rat hippocampus.Results Delayed neuron death was seen at 3 days after ischemia/reperfusin in CA 1 area of the hippocampus. A? immunoreactivity began enhanced at 2 d (A:0.082?0.011)after reperfusion, up to peak at 7 d(A:0.175?0.024), disapeared at 35 d.Conclusion Delayed neuron death was occurred after reperfusion of transiently incomplete forebrain ischemia in rat hippocampus,and at the same time, A? was up expression, which is suggested to be an important role of A? in neuron death after reperfusion of ischemic lesion.

OBJECTIVE: To study the activity of flavonoids WF extracted from Mallotus apelta against duck hepatitis B virus (DHBV).METHODS: One-day-old ducklings were infected with DHBV.7 days later the DHBV-infectious model was established successfully.The model ducklings were administrated with WF of 75 and 150 mg?kg-1 or lamivudine of 50 mg?kg-1 b.i.d.via i.g.gtt for 10 days consecutively.Serums were collected at 5th and 10th day after drug administration and 3th days after drug withdrawal.The level of DHBV-DNA in serum was detected by dot-blotting hybridization test.RESULTS: 75 and 150 mg?kg-1 WF reduced the level of DHBV-DNA significantly(P

Objective To explore the therapeutic effect of total hip replacement (T HR) in treating osteonecrosis of the femoral head (ONFH) after failed internal fixation of femoral neck fracture .Methods From January 2003 to June 2012 ,32 cases (19 left hips and 13 right hips) of ONFH after failed internal fixation of femoral neck fracture were treated with THR .There were 18 males and 14 females with an age range from 35 to 62 years (mean ,50 .6 years) .The ONFH was diagnosed at 8-26 months (mean ,17 .1 months) after internal fixation ;the THR were conducted 15-48 months after first surgery (mean ,27 .2 months) .According to Fi‐cat classifi cation ,there were 8 cases at stage Ⅲ and 24 cases at stage IV .The Harris score was (40 .9 ± 9 .8) .The prosthesis of bi‐ology was used .Results All wounds healed by first intention .All cases were followed up for 6-48 months (mean ,28 .3 months) . The Harris score was (90 .8 ± 4 .4) at last follow‐up ,showing significant difference when compared with the preoperative value (P<0 .05) .The hip function were excellent in 25 hips ,good in 5 hips ,fair in 2 hip ,and the excellent and good rate was 93 .8% . There were 1 cases of periprosthetic femoral fracture(type C) ,2 cases of proximal femoral splitting fractures fractures .After corre‐sponding treatment ,fracture was healed in all cases .There were no complications (infection ,loosening dislocation or subsidence , etc) .Conclusion Total hip replacement is an effective method for the treatment of ONFH after failed internal fixation of femoral neck fracture .

Based on the review of literature, the evaluation method and application of medication and functional exercise compliance of patients with stroke were summarized, to provide reference for nursing staff about the effective evaluation of medication and exercise compliance of patients with stroke, as well as the early and accurate judgment of patient′s compliance, further taking nursing intervention measures, to provide a basis for improving the medication and functional exercise compliance of patients with stroke and their rehabilitation effect.

BACKGROUND:Mkx (Mohawk, transcription factor) is one of the crucial factors in tendon formation, development and differentiation.
OBJECTIVE:To summarize the molecular structure, distribution and function of Mkx and its research process in the signaling pathways during tendon differentiation.
METHODS:The first author retrieved the databases of CqVip, CNKI and Medline from1990 to 2016 using the keywords of“Mkx, Mohawk, Irxl, tendon, tendon differentiation, tissue engineering, TGFβ, stem cel”in Chinese and English, respectively. The articles related to research process of Mkx in tendon tissue engineering were retrieved, and a total of 55 literatures were enrol ed final y.
RESULTS AND CONCLUSION:Mkx that expresses in various mesoderm-derived tissues plays an important role in the formation and development of tendon and tissue-engineered tendon formation. Although Mkx does not directly act on Scx (Scleraxis), it can regulate the differentiation of tendon progenitor cel s via transforming growth factor-β2 signaling pathway. Cel s from different species and different cel lines as wel as various cytokines for certain make different effects on Mkx involved in tendon tissue engineering.

Objective To probe into the inequality found in primary public health service available to the migrant population and permanent residents. Methods With on-site interviews, 581 migrant workers and 581 permanent residents in a county in Zhejiang province were surveyed, to learn the inequalities between the two in the expenditure, access and outcomes of the public health service accessible to each. Results only 7. 8% of the migrant population ever had access to medical aid, a ratio far below that of the permanent residents; 40. 9% of the migrant population may turn down medical service beyond their affordability, a ratio far higher; for the migrant population, their ratio of gynecological checkup is 58. 7%, lower than that of the permanent residents (67. 7%). Conclusion Resources and financial allocation to institutions of public health should be enhanced, and social medical and insurance system should be developed and improved, in an effort to encourage the equality of primary public health services accessible to various sectors of the population.
