Objective To discuss the effect of the concentration of dihydrotestostemne(DHT)in prostatic tissue treating by 5a-reductase inhibitors.Methods One hundred and twenty-one pros-tatic samples were selected:group A1(18 patients treating by epristeride for 1 month),group A2(22patients treating by epristeride for 3 months),group B1(23 patients treating by finasteride for 1 month),group B2(21 patients treating by finasteride for 3 months),group C(25 patients non-treating by 5α-reductase inhibitors),group D(12 samples of prostate from body).The concentration of DHT was measured by radio-immunity,Results The concentration of DHT in prostate declined after treating by epristeride 1 month and 3 months(66.21%and 70.60%,P＜0.05).The decline of the concentration of DHT in prostate after treating by epristeride 1 month was larger than 3 months(P＜0.05).The concentration of DHT in prostate declined after treating by finasteride 1 month and 3 months.There Was no signiificant difference of the concentration of DHT in prostate after treating by finasteride 1 month and 3 months.Conclusions The concentration of DHT in prostate can be declined after treating by epristeride and finasteride.The decline of the concentration of DHT is consistent aftertrealring by epristeride.The decline of the concentration of DHT is considerable between epristeride and finasteride.

OBJECTIVETo evaluate the long-term clinical outcomes of fractional flow reserve (FFR)-guided versus intravascular ultrasound (IVUS)-guided percutaneous coronary intervention (PCI) for intermediate coronary lesions.

METHODSA total of 226 patients with 293 intermediate coronary artery lesions (stenosis of 40%-70%) confirmed by coronary angiography were randomized into 3 groups to undergo PCI for a minimal lumen cross sectional area (MLA)<4 mm(2) (IVUS group, 98 lesions) or for a FFR<0.80 (FFR group, 101 lesions), or to receive standard medical treatment (medication group, 94 lesions). The primary outcome was major adverse cardiac events including death, myocardial infarction, and ischemia-driven target vessel revascularization at 1 year after the index procedure.

RESULTSThe baseline percent diameter stenosis and lesion length were similar between the 3 groups, but more patients in IVUS group than in FFR group received PCI (P<0.001). No significant difference was found in the incidence of major adverse cardiac events between the 3 groups (P=0.182).

CONCLUSIONBoth FFR- and IVUS-guided PCI strategy for intermediate coronary artery disease are associated with favorable outcomes, but IVUS-guided PCI based on the single index of MLA can increase the rate of revascularization therapy.

Objective:To investigate the developmental behavior of early term infants at 6 months and its difference from that of complete full-term infants.Methods:A healthy maternal and infant birth cohort in maanshan city, established in Maanshan Maternal and Child Health Hospital from June 2015 to June 2016. Birth outcomes were copied from the hospital electronic medical record system after delivery. The Chinese Ages and Stages Questionnaires was used to assess developmental behavior. The chi-square test and multivariate unconditional logistic regression model were used to analyze the differences in the behavioral development of early and full term infants.Results:The birth rate of early term infants was 24.74% (500/2 021). The detection rates of communication, gross motor, fine motor, problem solving and individual-social areas in early term infants were 2.1%, 3.2%, 6.1%, 6.3% and 2.7%, respectively. The detection rate of problem-solving area in early term infants was significantly higher than that in the full-term infants (6.3% vs. 3.7%, χ 2=5.42, P<0.05). After controlling for confounding factors, compared with full-term infants, the risk of problem-solving area in early infants was significantly increased ( OR=1.65, 95%CI:1.01-2.70, P<0.05). Conclusion:The risk of behavioral retardation in Early term infants is significantly higher than that in full-term infants, and long-term follow-up and appropriate early development promotion interventions are needed to improve their quality of life.
