Objective:
To explore the clinical value of echocardiography in differential diagnosis of segmental wall motion abnormalities in coronary heart disease(CHD), and to provide help for clinical treatment.
Methods:
From January 2017 to November 2018, 56 patients with segmental abnormal wall motion of CHD in Yuyao People's Hospital of Zhejiang Province were selected in the study.All patients were diagnosed by echocardiography and coronary angiography.The diagnostic coincidence rate, specificity, sensitivity, false negative rate, false positive rate and accuracy of echocardiography were evaluated.
Results:
Coronary angiography showed abnormal segmental wall motion in 56 patients, with 100.00% anastomosis rate.Echocardiography revealed abnormal segmental wall motion in 54 patients with CHD, 2 patients showed normal segmental wall motion, anastomosis rate was 96.43%.There was no statistically significant difference between the two diagnostic methods(χ2=0.635,

Objective To compare the efficacy of trimodality therapy and chemoradiation therapy (CRT) alone in patients with locally advanced resectable esophageal squamous cell carcinoma (SCC).Methods A total of 124 cases with locally advanced resectable esophageal SCC were retrospectively analyzed and classified into 2 groups.Fifty-four cases in trimodality group were treated with surgery and preoperative chemoradiation,while 70 cases in CRT alone group only received radiation and chemotherapy.Local tumor control,3-year survival and treatment-related mortality were assessed.Results The local recurrent rate of the resected patients was 18.5% in trimodality group and 35.7% in CRT alone group,respectively(x2 =4.445,P < 0.05).The 3-year progression-free survival (PFS) was 65.3% (95% CI 50.7-80.5) in trimodality group and31.9% (95%CI 19.6-44.2) in CRT alone group (P<0.05),while the overall survival (OS) 66.3% (95% CI43.0-89.6) and 34.4% (95% CI 21.1-47.7),respectively(P < 0.05).Treatment-related mortality was 1.9% in trimodality group and 2.9% in CRT alone group (P > 0.05).For CRT alone group,the sub-group analysis showed that there was no statistically significant difference in the 3-year OS between patients who received 50-50.4 Gy and those who received the dose over 50.4 Gy (39.9% 95% CI 18.5-61.3 vs.31.5% 95% CI 14.8-48.2,P >0.05).Conclusions Compared with CRT alone,trimodality therapy showed the superior local control,PFS and OS,with similar treatment-related mortality in the treatment of patients with SCC of esophagus.The role of surgery could not be replaced by CRT alone even with the augment of radiation dose.

Objective To evaluate the clinical efficacy of prophylactic cranial irradiation (PCI) in the treatment of surgically resected small cell lung cancer (SCLC).Methods Clinical data of SCLC patients undergoing radical resection surgery in Zhejiang Cancer Hospital from 2003 to 2015 were retrospectively analyzed.According to the treatment modality,all patients were allocated into the PCI and non-PCI groups.A total of 52 patients were finally included,including 19 patients in the PCI group (5 cases of stage Ⅰ,5 stage Ⅱ and 9 stage Ⅲ) and 33 in the non-PCI group (12 cases of stage Ⅰ,5 stage Ⅱ and 16 stage Ⅲ).Kaplan-Meier method was utilized for survival analysis.Cox proportional hazards model was adopted to analyze clinical prognosis.Results The median survival time was 32.9 months in the PCI group,and 20.4 months in the non-PCI group.The 2-year overall survival rate was 72% in the PCI group,significantly higher than 38% in the non-PCI group (P=0.023).The median brain metastasis-free survival (BMFS) was 32.5 months in the PCI group,and 17.1 months in the non-PCI group.In the PCI group,the 2-year BMFS rate was 89%,significantly better than 53% in the non-PCI group (P=0.026).Subgroup analysis demonstrated that PCI could confer survival benefit to patients with p-stage Ⅲ (p=0.031) rather than p-stage Ⅰ (P=0.924) and Ⅱ (P=0.094) counterparts.Multivariate analysis revealed that PCI (HR=0.330,P=0.041) was an independent prognostic factor of the overall survival.Conclusions PCI can reduce thr risk of brain metastasis rate and improve the overall survival of patients with surgically resected SCLC.
