Objective To evaluate the value of virtual touch tissue imaging quantification (VTIQ),which was combined with ultrasound Breast Imaging Reporting and Data System (BI-RADS),for differentiating benign from malignant breast lesions.Methods Totally 190 patients with 214 breast lesions were enrolled in this study.All lesions were classified according to the BI-RADS for sonography.The maximum,minimum and mean shear wave velocity (SWV) values on VTIQ in the lesions were obtained.The SWV between benign and malignant lesions were analyzed.Receiver operating characteristic(ROC) curves were plotted to determine the cut off value of VTIQ for differential diagnosis of breast lesions. Results Pathology confirmed 166 benign lesions and 48 malignant lesions.The SWVmax,SWVmin,SWVmean of malignant lesions were significantly higher than those of benign lesions (all P<0.001).The SWVmean 3.67 m/s as the best value in the diagnosis of benign and malignant lesions.The sensitivity,specificity,positive predictive value and negative predictive value of the combination of the SWVmean and BI-RADS classification standard in the diagnosis of benign and malignant breast lesions were 77.6%,97.5%,92.7%,91.3%,respectively.Conclusions The combination of VTIQ and ultrasonic BI-RADS can improve the ability of differential diagnosis of benign and malignant breast lesions.

Objectives: To explore the relationship between vascular active peptide, apelin level and blood pressure in a coastal population of Fujian province.
Methods: A total of 1031 subjects with the mean age of (55.1 ± 10.9) years in a coastal area of Fujian province were included in this cross-sectional study, and 416 subjects with male gender. The questionnaire survey, physical examination and plasma level of apelin measurement were conducted. Based on JNC-7 deifnition of hypertension, the subjects were divided into 3 groups: ① Hypertension group, the patients with systolic blood pressure (SBP)≥140 mmHg and/or diastolic blood pressure (DBP)≥90 mmHg, n=496. ② Pre-hypertension group, SBP at (120-139) mmHg and/or DBP at (80-89) mmHg without medication, n=314.③Normal BP group, SBP<120mmHg and DBP<80mmHg without medication, n=221. Based on 4 quartiles of apelin levels, the subjects were further divided into 4 groups:Q1 group, apelin<164.8 ng/ml, n=258. Q2 group, apelin at (164.8-<220.0) ng/ml, n=258. Q3 group, apelin at (220.0-283.1) ng/ml, n=258. Q4 group, apelin>283.1 ng/ml, n=257. One way analysis of variance, covariance analysis and multivariate linear regression analysis were used to study the
relationship between apelin level and BP.
Results: The apelin level in male gender (220.57 ± 78.87) pg/ml was lower than female gender (232.06 ± 81.17) pg/ml. Compared with Normal group, Pre-hypertension group had decreased apelin level, compared with Normal and Pre-hypertension groups, Hypertension group had decreased apelin level, P<0.05. Compared with Q1 group, Q2, Q3 groups presented decreased SBP, DBP and mean arterial blood pressure (MABP), and compared with other 3 groups, Q4 group had decreased SBP, DBP (not including Q2, Q3 groups) and MABP, P<0.05. With adjusted age and gender, SBP, DBP and MABP were signiifcantly different among 4 quartiles of apelin groups, P<0.05. Multivariate linear regression analysis indicated that SBP, DBP and MABP were negatively related to apelin level, such relationship remained the same after adjusting the other cardiovascular risk factors.
Conclusion: Apelin level dropping accompanying with BP increasing implies that vascular active peptide, apelin involved in BP regulation.

Objective To study the relationship between the severity of diastolic heart failure(DHF)and bone mineral density in the elderly. Methods Totally 80 elderly patients aged over 80 years who were tested as normal for cardiac diastolic function by Doppler tissue imaging(DTI) were selected and divided into four groups by the e/a ratio,i.e.,the normal group(n=18),the DHF 1 group(0.8≤e/a<1,n=25),the DHF 2 group (0.6≤e/a<0.8,n=22),and the DHF 3 group(e/a<0.6,n=15). And the other 20 healthy people by physical examination were set as the normal control group.All subjects underwent bone mineral density(BMD)measurement(including femoral neck,total femoral hip and lumbar vertebra 1?4) by dual energy X?ray absorptiometry. Results Bone mineral density(BMD)was significantly decreased(P<0.05)in DHF groups(DHF 1,DHF 2,and DHF 3). Bone mineral density significantly decreased along with the severity of DHF. Bone mineral density was positively correlated with the e/a ratio in the elderly with DHF(r=0.75,P<0.01). Conclusion The severity of diastolic heart failure is closely related to bone mineral density in the elderly. The severity of diastolic heart failure could predict osteoporosis.

Objective: To explore the relationship of plasma apelin and angiotensin II (Ang II) with hypertension and hypertension caused early renal damage in order to provide the information for hypertension treatment. Methods: A total of 671 participants were enrolled in this cross-sectional community investigation. All participants were above 30 years of age with local residency longer than 5 years and were divided into 2 groups: Control group,n=354 non-hypertension subjects and Hypertension group,n=317 patients with essential hypertension. The levels of apelin, Ang II, urine creatinine and urinary albumin were examined. The relationship between blood pressure and the ratio of urinary albumin to urine creatinine (UACR) and the relationship between blood pressure and apelin, Ang II were studied by Pearson correlation analysis and multi linear regression analysis. Results: Compared with Control group, Hypertension group had the lower levels of apelin and higher UACR, both P<0.01. The mean arterial pressure (MAP) was negatively related to Ln (apelin), positively related to Ln (Ang II), bothP<0.01. With adjusted gender, age and blood lipids, the above relationship still existed. In Hypertension group, the patients combining with the early renal damage had the lower level of apelin and higher level of Ang II, bothP<0.01. The relevant analysis indicated that Ln (UACR) was negatively related to Ln (apelin), positively related to Ln (Ang II), bothP<0.01. With adjusted gender, age, MAP and blood lipids, the above relationship still existed. Conclusion: The patients with hypertension or hypertension caused early renal damage have decreased apelin. Apelin is negatively related to Ang II, therefore, apelin might be used as a target for hypertension treatment in clinical practice.

Objective To explore the efficacy and safety of percutaneous transhepatic portal vein or transjugular intrahepatic portosystemie shunt (TIPS)to implant the portal vein metallic stent in treatment of cavernous transformation of portal vein (CTPV).Methods Clinical and imaging data of 8 patients with CTPV were retrospectively analyzed who were treated in our hospital.All patients were treated with metallic stent implantation in portal vein including 3 patients by TIPS and 5 by percutaneous transhepatic portal vein.Results All patients were successful in the stent implantation without any occurrence of serious complications such as intra-abdominal hemorrhage and so on.Intraoperative angiography showed blood circulated freely in these stents.1 day-2 weeks later,the patients symptoms of abdominal pain and gastrointestinal bleeding were obviously relieved or disappeared.Follow up 1 month-3 years,1 patient with stent occlusion after one year of operation,the blood flow recovery after stent reimplantation,and the remaining patients,color doppler ultrasound reflected patency of blood flows in their stents.No one suffered from gastrointestinal bleeding or abdominal pain again.Conclusion Implantation of portal vein metallic stent via percutaneous transhepatic portal vein or via TIPS in treatment of cavernous transformation of portal vein is safe and effective.

Objective:To explore the safety and efficacy of Castor branched stent-graft exclusion in the treatment of aortic dissection and aneurysm involving left subclavian artery.Methods:The clinical and imaging data of 88 patients with aortic dissection or aneurysm involving left subclavian artery diagnosed by CTA or DSA in our hospital from December 2017 to December 2019 were collected retrospectively, including 67 aorta dissections, 7 thoracic aortic aneurysms and 14 aorta penetrating ulcer. All patients were treated with branched stent-graft under the guidance of DSA. The postoperative curative effect and complications were observed. The paired t test was used to compare the maximum aortic diameter of the lesion before and 6 months after the operation. Results:Eighty-eight patients were successfully treated with integrated stent, the success rate of operation was 100%, and the disease-related symptoms of all patients were basically or completely relieved. The mortality rate within 1 month after the operation was 2.7% (2/88). The two deaths were complicated with other serious diseases before the operation, and the cause of death was not related the operation. All patients were followed up except 4 patients who lost contact after discharge. During the follow-up, there were 1 case of retrograde type A dissection, 1 case of new aneurysm of aortic arch, 2 cases of in-stent stenosis of left subclavian artery branch, 3 cases of mild stroke, no persistent endoleak and no death or other serious complications. The mean maximum aortic diameter at 6 months after operation [(34±4)mm] was significantly lower than that before operation [(38±6 mm)] ( t=6.63, P<0.05). Conclusion:Castor branched stent-graft is simple, mini-invasive and effective in the treatment of aortic dissection and aneurysms involving the left subclavian artery.

Objective:To analyze the current situation of pregnant women′s health promotion behavior in early pregnancy, and to explore the multiple mediating effects of self-efficacy and sense of coherence in family function and health promotion behavior.Methods:The convenience sampling method selected 208 early pregnant women who visited the obstetric clinic of the Affiliated Hospital of Qingdao University from August to December 2020 as the research object was used. The electronic questionnaires including self-made general information questionnaire, Family APGAR Questionnaire, General Self-Efficacy Scale (GSES), Sense of Coherence Scale (SOC-13), and the Health-Promoting Lifestyle ProfileⅡ (HPLP-Ⅱ) were provided to women.Results:The total score of health promotion behaviors for early pregnancy was (139.58 ± 17.27) points with a good level. The influencing factors such as exercise habits and medical payment methods had statistical significance in the effects of health-promoting behaviors in the first trimester of pregnancy ( t=4.68, -3.55, both P<0.05). Structural equation model revealed that the total effect value of family function on health-promoting behaviors was 2.654, the direct effect value was 1.729 and the indirect effect value was 0.925. Meanwhile, the mediating effects of self-efficacy, the sense of coherence and self-efficacy upon the sense of coherence accounted for 15.9%, 15.2% and 3.8% of the indirect effect respectively. Conclusions:Family function of pregnant women in early pregnancy can not only affect health promotion behavior through self-efficacy and sense of coherence, but also indirectly affect sense of coherence through self-efficacy, so as to affect health promotion behavior. Maternal related health workers can construct targeted intervention measures from the perspective of self-efficacy and sense of coherence to maintain and improve the health promotion behavior of pregnant women in the early stage of pregnancy.

Objective To evaluate the feasibility and clinical outcomes of interventional treatment of Budd-Chiari syndrome (BCS) associated with simultaneous upper gastrointestinal hemorrhage.Methods The clinical data of 32 patients of BCS with upper gastrointestinal hemorrhage from October 2015 to April 2008 in First Affiliated Hospital of Zhengzhou University were analyzed retrospectively.Variceal embolization and inferior vena cave (IVC) and/or hepatic veins (HV) angioplasty were performed simultaneously.Perioperative complications were observed.Portal vein pressures were measured through catheterization preand post-operation.Restenosis of IVC and HV,upper gastrointestinal hemorrhage were observed on followup.Results Percutaneous transluminal balloon angioplasty were successfully carried out in all patients:16 patients with IVC and 17 patients with HV stenosis underwent angioplasty without stent placement.Portography indicated one esophageal and gastric varices in 17 patients and two in 15 patients.All the varices were embolized successfully.The portal vein pressure reduced from (35.7±2.9) cmH2O to (31.2±2.5) cmH2O (P ＜ 0.05,1 cmH2O =0.098 kPa).Portal vein pressure reduced from (35.8± 3.0) cmH2O to (30.7±2.3) cmH2O in HV type BCS post-operation,and reduce from (35.6±3.0) cmH2O to (31.8±2.6) cmH2O in HV and IVC involved type,which indicated that portal vein pressure decreased more obviously after HV recanalization.On follow-up for 3 to 32 months (mean 11.7 ±7.8 months),7 patients with IVC and 5 patients with HV stenosis developed restenosis.Transluminal balloon angioplasty was performed.No upper gastrointestinal hemorrhage occurred during the follow-up period.Conclusion One-stage interventional treatment of BCS with upper gastrointestinal hemorrhage was safe and effective,and had satisfactory mediumlong term outcomes.
