Objective: To assess the clinical characteristics and identify the risk factors in the acute myocardial infarction (AMI) patients complicating with ventricular septal rupture (VSR). Methods: A retrospective study was performed on 96 AMI patients complicating with VSR, who were hospitalized in the Second Xiangya Hospital of Central South University, Hunan Provincial Peoples′ Hospital, the First Affiliated Hospital of University of South China, the Second Affiliated hospital of University of south China, Xiangtan Central Hospital from December 2007 to May 2017. There were 46 females and the age was (66.2±10.7) years (from 43 to 90 years). Patients were divided into in-hospital survival group (n=64) and in-hospital death group (n=32). The 96 patients were also divided into the early death group (survived ≤2 weeks after admission, n=50) and non-early death group (survived>2 weeks after admission, n=46). Multivariate logistic regression was used to analyze the independent risk factors of the early death. Results: Location of VSR was available in 71 patients, VSR was located at the apical or anterior septum near the apical region in 64.0% (32/50) patients with the anterior AMI, VSR was located at the posterior wall and basal inferior segment in 57.1% (12/21) patients with non-anterior AMI. Compared to the in-hospital survival group, patients in the in-hospital death group were older ((69.6±11.3) years vs. (64.6±10.1) years, P=0.031), incidence of non-ventricular aneurysm (71.9% (23/32) vs. 37.5% (24/64), P=0.001) and anterior AMI (84.4%(27/32) vs. 62.5%(40/64), P=0.028) was significantly higher in the in-hospital death group than in the in-hospital survival group. The comparison between the early death group and non-early death group showed that older age, female, no history of angina or myocardial infarction, Killip grade>Ⅲ, and non-ventricular aneurysm were related to increased risk of the early mortality in this patient cohort. Logistic regression analysis revealed that female (OR=5.109,95%CI 1.19-22.00, P=0.012), no history of angina or myocardial infarction (OR=23.34, 95%CI 3.44-158.37, P=0.001), Killip grade>Ⅲ(OR=5.35, 95%CI 1.26-22.66, P=0.019) and non-ventricular aneurysm (OR=6.30,95%CI 1.67-23.73, P=0.005) were independent risk factors for early death in this patient cohort. Conclusion The risk factors of in-hospital death include older age, non-ventricular aneurysm and anterior AMI. Female, no history of angina or myocardial infarction, Killip grade>Ⅲ and non-ventricular aneurysm are independent risk factors for the early death of AMI patients complicating VSR.

OBJECTIVETo evaluate surgical outcomes and the feasibility of robotic thyroidectomy and central neck dissection (CND).

METHODSThe clinical data of 40 patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND using the Da Vinci system through axillo-bilateral-breast approach in Jinan Military General Hospital of People's Liberation Army from February to December 2014 were analyzed retrospectively (robotic group). Other forty patients of papillary thyroid microcarcinoma underwent total thyroidectomy (or lobectomy and isthmusectomy) and CND by open approach were selected as the control (open group). Cosmetic satisfaction was assessed after a month postoperation by the numerical score system. t-test and χ(2) test were used to compare the clinical characters, total operative time, intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, visual analogue scale for pain, postoperative complications, and cosmetic effect between the 2 groups.

RESULTSAll 80 patients were diagnosed of papillary thyroid microcarcinoma. The total thyroidectomy (or lobectomy/isthmusectomy) with CND of 40 patients were successfully performed by da Vinci Si surgical system. The numbers of total thyroidectomy of robotic group and the open group were 36 and 37, respectively. The numbers of metastatic lymph nodes of robotic group and open group were 14 and 15, respectively. The operation time of the robotic group was (130±12) minutes, which was longer than that of open group (98±11) minutes (t=12.432, P<0.05). The study showed statistical significant difference between the two groups regarding the visual analog scale pain assessment (1.9±0.9 vs.3.9±1.1, t=8.900, P<0.05). There were no statistical significant difference of intraoperative estimated blood loss, postoperative hospital stay, number of lymph nodes removed, and the complication rate between the 2 groups.Postoperative cosmetic result was more satisfying on the robotic group (9.1±0.5) than open group (4.8±1.5) (t=17.200, P<0.05).

CONCLUSIONSThe robotic total thyroidectomy (or lobectomy and isthmusectomy) and CND has similar surgery safety and feasibility as open procedures. The robotic thyroidectomy is a good alternative surgical modality for patients with papillary thyroid microcarcinoma who wish to avoid neck scars.

Objective To evaluate the survival and prognostic factors of esophageal cancer treated with definitive ( chemo ) radiotherapy by applying novel radiation techniques including three-dimensional conformal radiotherapy (3DCRT) or intensity-modulated radiotherapy (IMRT). Methods Clinical data of 2762 patients with non-operated esophageal squamous cell carcinoma who underwent definitive ( chemo ) radiotherapy from 2002 to 2016 in 10 hospitals were retrospectively analyzed.The prognostic factors were also identified and analyzed. Results The median follow-up time was 60. 8 months. The 1-, 2-, 3-and 5-year overall survival (OS) of all patients was 71. 4％,48. 9％,39. 3％,and 30. 9％,respectively.The 1-,2-,3-and 5-year progression-free survival (PFS) was 59.5％,41.5％,35.2％,and 30％,respectively.The median survival was 23 months.The median time to progression was 17. 2 months.Multivariate analysis demonstrated that age, primary tumor location, clinical stage, tumor target volume, EQD2 and treatment mode were the independent prognostic factors for OS.Primary tumor location,clinical stage,tumor target volume and EQD2 were the independent prognostic factors for PFS. Conclusions In this first large-scale multi-center retrospective analysis of definitive ( chemo) radiotherapy for esophageal squamous cell carcinoma in China, the 5-year OS of patients with esophageal squamous cell carcinoma is significantly improved by 3DCRT, IMRT combined with chemotherapy drugs. However, the findings remain to be validated by prospective clinical trials with high-level medical evidence.
