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 identify the quality of life (QOL)and major influencing factors for migrant workers in Zhejiang province.Methods The QOL of 1217 migrant workers and 1387 permanent urban residents in Zhejiang province were measured by WHOQOL-BREF scale (Chinese version)in a stratified sampling.A multiple linear regression model was used to analyze the relationship between the factors and the scores of the four domains.Results There were no significant statistical differences(P>0.05)found in the scores of physical health,social relationship and general health between migrant workers and urban residents.Their scores of psychological health,surrounding conditions and general quality of life,however,were found lower than urban residents (3.5 ± 0.8 vs 3.6 ± 0.8).Influencing factors for their psychology were education,family conflicts and appetite; those for their surrounding conditions were daily average work hours and appetite.Conclusion Given improvements in the quality of life of migrant workers,rooms to improve were found in such scores as psychological health and surrounding conditions.

Objective:To investigate the effects of electroacupuncture (EA) at Neiguan (PC 6) and Baihui (GV 20) by observing the changes of CCAAT/enhancer-binding protein(C/EBP) homologous protein (CHOP) and caspase-12 gene expressions in rats after cerebral ischemia-reperfusion injury (IRI), and explore whether the apoptosis pathway of endoplasmic reticulum stress (ERS) is involved in the protective mechanisms of EA.
Methods:Sixty rats were randomly assigned to five groups (12 in each group): a normal control group (group A), a sham-operation group (group B), an operation group (group C), an Edaravone group (group D) and an EA group (group E). The cerebral IRI rat model was induced by middle cerebral artery occlusion (MCAO) using intraluminal monofilament. 2,3,5-triphenyl tetrazolium chloride (TTC) staining was adopted in the measurement of cerebral infarction volume. Real-time polymerase chain reaction (RT-PCR) was used to determine the mRNA expressions of CHOP and caspase-12.
Results: Compared with group A and group B, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group C, group D and group E were increased, with statistical significances (P<0.05 orP<0.01); compared with group C, the volume of cerebral infarction and mRNA expressions of CHOP and caspase-12 in group D and group E were decreased significantly (P<0.05 orP<0.01); there were no significant differences between group D and group E in comparing the above items (P>0.05).
Conclusion:EA at Neiguan (PC 6) and Baihui (GV 20) can effectively suppress the volume of cerebral infarction. Furthermore, the underlying mechanism of EA at Neiguan (PC 6) and Baihui (GV 20) is possibly related to the down-regulation of CHOP and caspase-12 mRNA expressions, so as to decrease cell apoptosis.

Objective To find out the optimal operative methods for the patients with osteonecrosis of the femoral head according to age and the staging. Methods The current study assessed 202 patients(242 hips)from 1998 to 2008 with an average follow-up of 6.3years (range,1 -10 years), who were operated according to age and staging by Ficat or Catterall. The mean age of the patients was 35.3 years(range,4 -81 years). All patients were evaluated with both clinical and radiographical criterion. Results The postoperative excellent and good rate were 87.2% ,88.8% and 85.7% in each group respectively. The mean Hariss score increased (P <0.05) and the mean VAS score decreased (P < 0.05) in youth group and old group. Conclusions Children who were younger than six years of age and with Catter-all Ⅱ-Ⅲ involvement should be treated by ascularized iliac or greater trochanter bone periosteal flaps. Patients who were less than forty years of age, with Ficat Ⅱ-Ⅲ should be treated by ascularized iliac or greater trochanter bone flaps. For patients with age older than 50 years or younger than 50 years but with severe forms, hybrid or cememtless total hip arthroplasty may be the optimal operation.
