ABSTRACT
Objective:To compare the effectiveness and safety of laparoscopic hepatectomy (LH) versus radiofrequency ablation (RFA) in treatment of hepatocellular carcinoma (HCC).Methods:The medical literatures on LH and RFA for HCC were searched in PubMed, Web of Science, Embase, VIP, Wanfang, CNKI and other electronic databases. The retrieval date was from database construction to June 7, 2021. According to the inclusion and exclusion criteria, studies were extracted by two authors, and Revman 5.3 software was used to conduct a meta-analysis to compare differences in operation time, blood loss, length of hospital stay, total complications, overall survival and disease-free survival outcomes between the LH group and the RFA group.Results:Of 3 690 patients who were included in 32 studies, there were 1 708 patients in the LH group and 1982 patients in the RFA group. Meta-analysis showed that compared with the LH group, the RFA group had significantly shorter surgical duration ( MD=-86.41, 95% CI: -116.21--56.60), less blood loss ( MD=-213.22, 95% CI: -273.43--153.00), shorter hospital stay ( MD=-3.23, 95% CI: -4.13--2.32), and lower incidence of complications ( OR=0.33, 95% CI: 0.26-0.43). However, local recurrence rate was significantly higher ( OR=1.83, 95% CI: 1.38-2.41). (All P<0.05). The 5-year survival rate of the LH group was significantly better than the RFA group ( OR=0.68, 95% CI: 0.51-0.90, P=0.008). Conclusion:LH provided better overall survival outcomes and lower local recurrence rates than RFA in HCC patients.
ABSTRACT
Objective To study ultrasonic parameters characteristics of lactation mastitis,breast cancer by using color doppler flow imaging(CDFI)and ultrasonic elastography(UE),and to explore its clinical value.Methods Retrospective analysis was conducted in the clinical data of 85 female patients (a total of 85 breast lesions).All patients were confirmed by pathology,and according to the results of pathology,they were divided into non lactation mastitis group(group NLM,a total of 28 cases),breast cancer group(group Ca,a total of 57 cases).All patients accepted CDFI and UE before treatment,and compared ultrasound parameters between the two groups.Results The proportions of class 0~I(71.43%)and RI<0.7(82.14%)in group NLM were significantly higher than those in group Ca,while the proportions of classⅡ ~Ⅲ(28.57%)and RI≥0.7 (17.86%)were significantly lower than 75.44%,84.21% in group Ca(χ2 =17.185,35.217,all P<0.05).The UE ratings(1.75 ±0.97)and the strain rate ratio (1.64 ±0.83)in NLMgroup were lower than (4.19 ±0.74),(5.03 ±1.08)in group Ca(t=-12.873,-14.623,all P<0.05).The accuracy of CDFI +UE(89.41%)was higher than the accuracy of UE(76.47%)or the accuracy of CDFI(67.06%)(χ2 =12.337,P<0.05).Conclusion CDFI,UE have a certain diagnosis ability for non lactation mastitis and breast cancer,combining both can obtain better diagnostic value,which is worthy of clinical application.
ABSTRACT
Objective:To investigate the characteristics of real-time three plane strain rate imaging of left atrial function in the patients with primary hypertension and coronary artery stenosis, and to evaluate its clinical application value.Methods:Total 82 patients with primary hypertension were selected and divided into primary hypertension group (EH group,n=42)and primary hypertension complicated with coronary artery stenosis group (EHCHD group,n=40).In addition,the physical examination people were selected as control group (n=42).All the subjects were examined by conventional echocardiography,and the left atrial function in real-time three plane strain rate imaging was analyzed.The parameters of conventional echocardiography and real-time three plane strain rate imaging were compared.Results:Compared with control group,the systolic left atrial mean peak strain rate (SRs),early diastolic left atrial mean peak strain rate (SRe)and SRe/SRa of the patients in EH group and EHCHD group were significantly decreased (P < 0.05);the atrial systolic mean peak strain rate (SRa)and Time-SRa in EH group and EHCHD group were significantly increased (P <0.05).Compared with EH group,SRs,SRe and SRe/SRa in EHCHD group were obviously decreased (P < 0.05 );SRa and Time-SRa were significantly increased (P <0.05).Conclusion:Real-time three plane strain rate imaging can easily and accurately analyze the left atrial function in the patients with essential hypertension and coronary artery stenosis,it is worth to popularize in clinical application.
ABSTRACT
Objective To evaluate the sensitive indicator of left ventricular rotation/torsion assessed by two-dimensional speckle tracking imaging (STI) and Logistic regression analysis,and to investigate the clinical value of the sensitive indicator for assessment of left ventricular dysfunction in patients with chronic cor pulmonale (CCP).Methods 36 patients with CCP (CCP group) and 38 healthy controls (control group) were included in this study.Imaging in parasternal short-axis view (in basal and apical level) were selected.Parasternal short-axis views at mitral valve and apical levels were collected.Basal peak rotation,apical peak rotation,peak torsion,basal end-systolic rotation,apical end-systolic rotation and end systolic torsion were measured with Echo PAC software.Relevant indicators of left ventricular rotation/torsion were selected by using logistic regression analysis and the regression equation was established.Optimal values of specific parameters (Peak torsion and end-systolic torsion) were calculated with receiver-operating characteristic (ROC) curve.Results Specific parameters of rotation/torsion were significantly reduced in patients with CCP as compared with controls (all P＜0.01).Logistic regression analysis showed that end-systolic torsion and peak torsion were correlated with CCP (OR=0.473 and 0.706,P=0.007 and 0.011).Cut-off value of peak torsion for predicting left ventricular dysfunction was 12.070°,the area under the ROC curve (AUC) was 0.819 (95％ CI:0.683-0.956),the sensitivity was 84.6％,and the specificity was 73.9 ％.Cut-off value of end-systolic torsion for predicting left ventricular dysfunction was 10.680°,AUC was 0.875(95％CI:0.744 1.000),the sensitivity was 84.6％,and the specificity was 91.3％.Conclusions Two-dimensional speckle tracking imaging can sensitively assess left ventricular torsion and evaluate the left ventricular dysfunction in patients with CCP.
ABSTRACT
Objective To investigate the value of left ventricular function in patients with chronic pulmonary heart disease(CPHD) using strain rate imaging (SRI).Methods This study included 64 patients with CPHD (30 patients with compensatory function and 34 with decompensatory function) and 30 normal control.Peak systolic strain rate (SRs),peak early diastolic strain rate (SRe) and peak late diastolic strain rate (SRa)of left ventricular basal and middle segments were measured,and then mean peak strain rate (mSR) was calculated.The above digital parameters were analyzed compared with the conventional echocardiographic indices.Results The indices (mSRs,mSRe,mSRe/mSRa)in CPHD were reduced and mSRa increased as compared with those in controls (all P=0.000).And the above indices showed the same change when decompensatory group was compared with compensatory group (P=0.000,0.038,0.015,0.001).Negative correlation was noted between LVEF and mSRs in patients with CPHD (r=0.75,0.82;P=0.000).Conclusions LVEF is negatively related with mSRs in CPHD patients.mSRs can reflect the status of left ventricular function.SRI is a more sensitive tool in quantitative evaluation of left function of CPHD.
