Objective To evaluate the value of diagnosis in fallopian tube patency by using four dimensional transvaginal hysterosalpingo-contrast sonography (4D-HyCoSy) and two-dimensional transvaginal hysterosalpingo-contrast sonography(2D-HyCoSy) with SonoVue in infertile women.Methods First,fifty seven infertile women(113 fallopian tubes) were examined by 4D-HyCoSy,then examined by 2D-HyCoSy,and the results of examination were respectively recorded.Results By 4D-HyCoSy,54 fallopian tubes were patency,42 were unobstructed but unsmooth flow,17 were obstructed.By 2D-HyCoSy,48 of them were patency,40 of them were unobstructed but unsmooth flow,25 of them were obstructed.Three fallopian tubes were obstructed by 4D-HyCoSy,but by 2D-HyCoSy they were patency.Eleven fallopian tubes were patency by 4D-HyCoSy,but obstructed by 2D-HyCoSy.Nine fallopian tubes were patency by 4D-HyCoSy,but fimbriated extremity of these fallopian tubes were far awary from homolateral overys.They were unuseful.Eighteen patients underwent laparoscopy,30 fallopian tubes (91.4%) were concordant with laparoscopy using combination of 4D-HyCoSy and 2D-HyCoSy,the sensitivity,specificity,positive predictive value and negative predictive value were 86.7 %,90.5 %,86.7 % and 90.5 %.The concidence rate,sensitivity,specificity,positive predictive value and negative predictive value were 85.7%,84.6%,90.5%,84.6% and 86.4% by 4D-HyCoSy and 71.4%,64.7%,70.0%,64.7% and 77.8% by 2D-HyCoSy,respectively.Accuraty of combination of 4D-HyCoSy and 2D-HyCoSy was similar with laparoscopy.Five patients appeared moderate pelvic pain,three patients appeared mild pelvic pain,two patients appeared nausea and vomiting.None need resuscitation.Conclusions Combination of 4D-HyCoSy and 2D-HyCoSy can more accurately diagnose fallopian tube patency,it can judge if fallopian tube is valuable or not and reduce misdiagnosing.It is a simple,safe,accurate,efficient method for evaluating the fallopian tube patency.

Objective To evaluate the changes in eutopic endometrial vascularity of endometriosis using three-dimensional power Doppler ultrasound.Methods Forty-four women with endometriosis and 51 normal controls were studied by three-dimensional power Doppler ultrasound.Eutopic endometrial volume,vascularization index (VI),flow index (FI) and vascularization flow index (VFI) were calculated using VOCAL software.Results In proliferative phase,the mean VI was (5.499 ± 5.153)% in patients with endometriosis and ( 1.135 ± 1.333) % in normal controls ( P <0.001 ),the mean FI was (28.832 ± 4.279)dB in patients with endometriosis and (25.544 ± 3.465)dB in normal controls ( P =0.006),the VFI was (1.769 ± 1.981 )dB in patients with endometriosis and (0.321 ± 0.397)dB in normal controls( P =0.002).In secretory phase,the mean VI was (8.693 ± 5.940) % in patients with endometriosis and ( 1.014±0.968)% in normal controls ( P <0.001); the mean FI was (30.689 ± 3.632)dB in patients with endometriosis and (24.748 ± 3.811 )dB in normal controls( P <0.001 ),the VFI was (2.753 ± 2.044)dB in patients with endometriosis and (0.27 ± 0.293)dB in normal controls( P =0.001 ).Both in proliferative and secretory phase,no significant difference in endometrial volume between the two groups was observed ( P =0.108 and 0.068,respectively).Conclusions Three-dimensional power ultrasound provides a useful tool to investigate eutopic endometrial vascularization of endimetriosis.

Objective:To investigate the relationship between self-management ability and self-efficacy in coronary heart disease (CHD) patients, and the influential factors.Methods:From April to June 2016, a questionnaire survey was conducted among 236 patients with coronary heart disease selected by simple random sampling method in the outpatient clinic of Pengpu Community Health Service Center; and the Coronary Artery Disease Self-management Scale and self-efficacy questionnaire were used in the survey. The correlation between scores of the two scales was analyzed; the scores were compared between patients with percutaneous coronary intervention (PCI) and those without PCI, between patients with myocardial infarction (MI) and those without MI. Multiple linear regression was performed to elucidate the influencing factors of self-management ability and self-efficacy of CHD patients.Results:The mean scores of self-management ability and self-efficacy were (75.5±15.5) and (24.8±10.8), respectively. The self-management ability was significantly correlated with self-efficacy in CHD patients(r=0.398-0.683, P<0.05). The self-management score of patients with PCI was higher than those without PCI[ (80.4±14.9) vs.(72.5±15.1), t=3.38, P<0.01]. The scores of self-management[(85.0±16.4) vs.(72.9±14.2), t=5.14, P<0.01]and self-efficacy[(29.3±12.0) vs. (23.6±10.2), t=3.39, P<0.01] of patients with MI were higher than those without MI. Multiple linear stepwise regression analysis indicated that age over 65, history of MI, history of PCI, history of smoking and self-efficacy score were all factors influencing self-management behavior in patients with CHD ( R=0.735; R2=0.540; F=26.451, P<0.01). Smoking history and self-management score were the influencing factors of self-efficacy in patients with CHD ( R=0.690; R2=0.476; F=20.425, P<0.01). Conclusion:The self-efficacy of patients with CHD is closely related to their self-management behavior, so we should strengthen their self-efficacy and improve their self-management level by comprehensive measures, particularly for patients without PCI.
