Objective To investigate the clinical value of serum human epididymis protein 4 (HE4), carbohydrate antigen 125 (CA125) combined with risk of ovarian malignancy algorithm (ROMA) index in the diagnosis of ovarian cancer. Methods A total of 541 patients in the Department of Gynaecology in Baoji Central Hospital from August 2016 to February 2018 were collected. The serum HE4 and CA125 levels were measured by using electrochemiluminescence immunoassay in 226 cases of ovarian cancer (ovarian cancer group), 315 cases of ovarian benign disease (ovarian benign disease group) and 100 female healthy people (the control group). ROMA index was calculated according to ROMA model and the results were analyzed statistically. Results The levels of serum HE4, CA125 and ROMA index were significantly different in premenopausal and postmenopausal ovarian cancer group, ovarian benign disease group and the control group (all P<0.05). The sensitivity and Yonden's index of the three combined diagnosis of serum HE4, CA125 and ROMA for premenopausal ovarian cancer were 97.01 ％ and 77.01 ％ respectively, which were higher than those of a single detection (HE4:79.37％, 69.11％;CA125:76.06％, 66.38％;ROMA index:89.55％, 72.41％;χ2sensitivity=12.35, P=0.000;χ2Yonden's index=6.460, P=0.013. The sensitivity and Yonden's index ofthe three combined diagnosis of serum HE4, CA125 and ROMA for postmenopausal ovarian cancer were 98.99 ％ and 82.99 ％ respectively, which were higher than those of a single detection (HE4: 86.90 ％, 79.40 ％; CA125: 82.98 ％, 76.31 ％; ROMA index: 93.54 ％, 80.64 ％; χ2sensitivity = 14.25, P = 0.000;χ2Yonden's index= 4.822, P= 0.031). The area under the curve of the combined detection of three indicators was higher than that of a single detection (premenopausal group: 0.871 vs. 0.682, 0.626, 0.708; postmenopausal group: 0.981 vs. 0.724, 0.705, 0.833), and there were significant differences (premenopausal group: χ2 =11.24, P= 0.000; postmenopausal group: χ2= 16.38, P= 0.000). Conclusion The combined detection of serum HE4, CA125 and ROMA index can increase the sensitivity and accuracy for diagnosing ovarian cancer, which can provide a more reliable basis for diagnosis and screening of ovarian cancer.

Objective To observe and analyze the effect of HbA1c level on macular microcirculation in patients with type 2 diabetes mellitus (T2DM).Methods A cross-sectional study.One hundred and twenty-four T2DM patients (124 eyes) without diabetic retinopathy who diagnosed by the examination of fundus color photography in Lixiang Eye Hospital Of Soochow University during September to December 2017 were enrolled in this study.There were 59 males (59 eyes) and 65 females (65 eyes),with the mean age of 65.06±7.99 years old.All patients underwent BCVA,fundus color photography,and OCT angiography (OCTA).The history of diabetes,hypertension and dyslipidemia were recorded in detail.According to the HbA 1 c level,patients were divided into three groups,HbA1c ideal control group (group A,HbA1c ＜7％,67 eyes),HbA1c control group (group B,7％≤HbA1c≤9％,44 eyes),and HbA1c poor control group (group C,HbA1c＞9％,13 eyes),respectively.The 3 mm × 3 mm range of the macular area was scanned by OCTA instrument.The vascular density (VD) and skeleton density (SD) of nonsegmented retinal layer (NRL),superficial retinal layer (SRL) and deep retinal layer (DRL) in the macular area and foveal avascular zone (FAZ) area,non-circularity index,axial rate (AR) of SRL were measured.The correlation between HbA1c,BCVA and VD,SD ofNRL,SRL,DRL was analyzed statistically with Spearman correlation test.The correlation between systemic factors and the above indicators was analyzed statistically with linear regression analysis.Results The results of linear regression analysis showed that HbA1 c was significantly correlated with VD (t=-3.237,-3.156,-2.050) and SD (t=-0.3.45,-3.034,-2.248) of NRL,SRL and DRL (P＜0.05);but no correlation with FAZ,non-circularity index and AR (t=1.739,0.429,1.155;P＞0.05).The differences of VD (F=6.349,5.981,3.709),SD (F=7.275,6.085,1.904) and AR (F=0.027) of NRL,SRL and DRL in group A,B and C were statistically significant (P＜0.05);but the differences of FAZ (F=1.904),non-circularity index (F=0.280) was not statistically significant (P＞0.05).Significant differences (P＜0.05) of VD and SD of NRL were found between group A and B (t=1.987,2.201),group A and C (t=3.365,3.572),group B and C (t=2.010,2.076).Significant differences (P＜0.05) of VD and SD of SRL were found between group A and B (t=2.087,2.168),group A and C (t=3.197,3.194).There were significant differences (P＜ 0.05) in SD of DRL between group A and B (t=2.239),group A and C (t=-2.519).There was significant difference in VD of DRL between group A and C (t=2.363).The results of Spearman correlation analysis showed that HbA1c was negatively correlated with VD (r=-0.273,-0.255,-0.222;P=0.002,0.004,0.013) and SD (r=-0.275,-0.236,-0.254;P＜0.05) ofNRL,SRL,DRL;positively correlated with FAZ and BCVA (r=0.221,0.183;P＜0.05).BCVA was negatively correlated with VD (r=-0.210,-0.190,-0.245) and SD (r=-0.239,-0.207,-0.296) of NRL,SRL,and DRL (P＜0.05),but not correlated with FAZ (r=0.099,P＞0.05).Conclusion The decrease of macular perfusion and the morphological change of FAZ accompanied by HbA1c increased.
