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.

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 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 effect of various methods determining lung volume and fraction dose on the lung dose-volume parameters for lung cancer patients. Methods Twenty patients with lung cancer were rantdomly enrolled into our study and the plan of three dimensional eonformal radiation therapy(3DCRT)was designed by Varian Eclipse TPS.The lung volumes and the dose-volume parameters were measured under CT value of-300- -980, -400- -980 and -500- -980.Under CT value of -400- -980,total lung volumes were confirmed.The dose-volume parameters of V30,V20,V10 and mean lung dose(MLD)were reevaluated after GTV,CTV and PTV were subtracted from the total lung volumes and when the fraction dose was elevated from 2.0 Gy to 10.0 Gy. Results When the CT value ranged from-300--980 to-500--980,the median reduction of the total lung volumes(-9.10%)was significantly higher than that of V30,V20,V10 and MLD(-3.18%,-1.13%,0.82%and-0.79%,respectively).When the total lung volume was fixed at CT value of-400--980,the alterations of V30,V20,V10 and MLD became more apparent as the increase of the subtracted lung volume,among which the alteration of V30 was most significant while V10 the least.Among five cases with a fixed total dose of 60 Gy and PTV less than 140 cm3,the V30,V20,V10 and MLD were increased to a similar extent(about 40%)when the fraction dose was increased from 2.0 Gy to 10.0 Gy.MLD was increased(36%)when the fraction dose was above 6.0 Gy. Conclusions When CT value ranges from-300- -980 to-500- -980,the total lung volume is influenced most.The alteration of V30,being statistically significant,might have some significance but is not enough to determine the plan of radiotherapy clinically.The alteration of V20、V10 and MLD is not statistically significant.When the overlapped target volume is subtracted from the total lung volumes,the alteration of V30 is the most sign:tifhcant while V10 the least.The fraction dose,being the most consuming factor(＞10%)when comparing with the CT valHe and targeted volume,can significantly influence the dose-volume parameter.

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.

Objective To describe depression in liver transplant(LT)recipients and explore their coping styles.Methods One hundred transplant recipients were divided into three groups according to the time after LT:one to six months after the operation(group1),six months to one year(group2)and one to three years after the operation(group3).A self-rating depression scale(SDS)was used to measure their depression levels,and a Medical Coping Modes questionnaire(MCMQ)Was used to investigate their coping styles.The results were compared with those from a general population,and the relevance of depression symptoms and coping styles was analysed. Results The average SDS score of all the LT recipients was 41.03±7.14(42.90±7.18 for group 1.40.71±7.97 for group 2 and 39.69±6.00 for group 3).The average depression scores of the three groups were all significantly higher than in the normal population,but there was no statistically significant difference among the three groups.The depression scores were negatively correlated with the confrontation aspect of coping style,while positively correlated with avoidance and resignation.Conclusion LT recipients tend to be depressed,and the level of depression is strongly related with their coping styles.
