Objective:To investigate the clinical efficacy of neoadjuvant chemotherapy for the resectable locally advanced adenocarcinoma at the gastroesophageal junction.Methods:A retrospective cohort study was conducted to analyze 86 patients with resectable locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma at the gastroesophageal junction (T 3-4N +M 0) who were admitted to the Panzhihua Central Hospital of Sichuan Province from January 2013 to January 2016. All the patients were divided into the neoadjuvant chemotherapy group [preoperative XELOX regimen (oxaliplatin + capecitabine) adjuvant chemotherapy + surgery + postoperative XELOX regimen adjuvant chemotherapy, 46 cases] and non-neoadjuvant chemotherapy group (surgery + postoperative XELOX regimen adjuvant chemotherapy, 40 cases) according to whether neoadjuvant chemotherapy was performed before surgery. The total gastrectomy + Roux-en-Y esophagojejunostomy + D 2 lymphadenectomy or proximal subtotal gastrectomy + esophageal gastric remnant anastomosis + D 2 lymphadenectomy were applied to patients by the same team of doctors. The observation indicators included treatment situations, results of postoperative pathological examination and prognosis in the two groups. Results:In the neoadjuvant chemotherapy group, 25 patients (54.3%) had partial remission (PR), 21 patients (45.7%) had stable disease (SD), the clinical response rate was 54.3% (25/46), tumor control rate was 100.0% (46/46), and clinical stage reduction rate was 37.0% (17/46). Compared with the non-neoadjuvant chemotherapy group, the neoadjuvant chemotherapy group had a higher R 0 resection rate [100.0% (46/46) vs. 80.0% (32/40), χ2 = 4.024, P = 0.045], and in the neoadjuvant chemotherapy group, the pathological complete remission [tumor regression grade (TRG) 0] rate was 13.0% (6/46), and the overall pathological response (TRG 1 + TRG 0) rate was 56.5% (26/46). The postoperative pathological examination showed that the neoadjuvant chemotherapy group and the non-neoadjuvant chemotherapy group had statistically significant differences in the longest tumor diameter, vessel carcinoma embolus, perineural invasion, and pathological TNM staging (all P < 0.05). However, there was no statistical difference in the total humber of lymph nodes, the number of positive lymph nodes, pathological T stage, N stage, and human epidermal growth factor receptor 2 (HER2) expression in specimens (all P > 0.05). In the neoadjuvant chemotherapy group, 6 patients had grade 3 adverse reactions, and chemotherapy was suspended or the dose was adjusted. Adverse reactions in the blood system included the red blood cells reduction, white blood cells reduction and thrombocytopenia. Other adverse reactions included nausea, vomiting, and decreased appetite. There were no deaths related to radiotherapy. In the neoadjuvant chemotherapy group, the median tumor-free survival time was 20 months (5-36 months), and the 1-year and 3-year tumor-free survival rates were 89.5% and 52.4%, respectively; the median postoperative overall survival time was 20 months (9-36 months), and the 1-year and 3-year overall survival rates were 91.0% and 48.0%, respectively; 12 patients had tumor recurrence. In the non-neoadjuvant chemotherapy group, the median tumor-free survival time was 19 months (10-35 months), and the 1-year and 3-year tumor-free survival rates were 87.3% and 30.0%, respectively. The median postoperative overall survival time was 20 months (10-35 months), the 1-year and 3-year overall survival rates were 87.0% and 18.6%, respectively; 14 patients had tumor recurrence. There was a statistical difference in the tumor-free survival between the two groups ( χ2 = 4.522, P = 0.03), and there was no statistical difference in the overall survival between the two groups ( χ2 = 3.717, P > 0.05). Conclusions:XELOX regimen neoadjuvant chemotherapy is safe and effective for patients with resectable locally advanced Siewert type Ⅱ and Ⅲ adenocarcinoma at the gastroesophageal junction. It can decrease the tumor clinical stage and increase the R 0 resection rate and tumor-free survival rate.

Objective:To explore the early surgical outcomes of Thoracoscopic Transmitral Myectomy(TTM) on patients with hypertrophic obstructive cardiomyopathy(HOCM).Methods:Preoperative echocardiography and cardiac magnetic resonance were used to evaluate the patient's hypertrophy extent, mitral valve morphology and function. Myocardial resection was performed via the trans-mitral approach under total thoracoscopy, and the surgical methods and early results were analyzed.Results:From April 2019 to October 2019, a total of 15 cases of TTM were performed by a single surgeon in our ward. Preoperative imaging evaluation revealed that 6 patients(40.0%) had predominantly hypertrophic basal septum while another 9 patients(60.0%) had concomitant midventricular septal hypertrophy. Two(13.3%) patients were interrogated ruptured posterior mitral chord by preoperative echocardiogram. After myocardial resection, the mitral valve was treated as follows: 11 patients(73.3%) underwent anterior leaflet enlargement, and 3(20.0%) were directly reattached to mitral valve annulus, and 1(6.7%) underwent bioprosthetic mitral replacement. There was no case of perioperative death, ventricular septal perforation, residual left ventricular outflow tract obstruction and complete atrioventricular block. Median aortic crossclamp time, cardiopulmonary bypass time, postoperative ventilator use time, ICU stay time, and postoperative hospital stay were 129.0min(116.0, 147.0), 184.0 min(158.0, 227.0), 22.0 h(9.0, 26.0), 3 days(2, 7) and 9 days(7, 14) respectively. No patient lost to follow up, the median follow-up time was 4 months(2, 5). One patient(6.7%) underwent mitral angioplasty three months after surgery due to a tear in the A3 area; the ventricular septal thickness and left ventricular outflow tract pressure decreased significantly(preoperative vs follow-up), and were(19.3±3.3)mm vs. (8.9±4.4) mm( P=0.001), (90.8±23.2)mmHg vs. (8.9±4.4) mmHg(1 mmHg = 0.133kPa)( P<0.001) respectively; no residual SAM was observed during follow-up. Patients with moderate-to severe mitral regurgitation were decreased from 12(80.0%) before surgery to 1(6.7%) during follow up( P<0.001). Conclusion:TTM is a safe and effective procedure for HOCM patients with appropriate surgical indications, providing better exposure to septum from basal to apical area, eliminating left ventricular outflow tract obstruction and SAM-related mitral regurgitation. The anterior mitral valve leaflet should be carefully treated during surgery to reduce the occurrence of residual mitral regurgitation resulted in inappropriate selection of patch size and suturing technique.

Objective:To examine the short and long-term clinical outcomes of total arterial coronary artery bypass grafting.Methods:Clinic data of 208 patients with left main and multiple vessel coronary artery disease and undertaken total arterial coronary artery bypass grafting from February 2009 to December 2019 in Department of Cardiac Surgery, Rui Jin Hospital, Shanghai Jiao Tong University School of Medicine were analyzed retrospectively. There were 188 males and 20 females with an age of (54.7±10.7) years (range: 32 to 79 years). The harvest of arterial conduits and grafting strategies were depended upon the individual patient characteristics and surgeon′s experience. Left internal thoracic artery (LITA) was applied in 207 cases, right internal thoracic artery (RITA) in 38 cases (bilateral internal thoracic artery (BITA) in 37 cases), and radial artery (RA) in 187 cases (188 grafts). The graft number per case was 2.6±0.7 (range: 2 to 4). Surgical procedures was completed with off-pump technique in 98.1% patients (204/208). Subgroup analysis was carried out between subgroup BITA ( n=37) and subgroup SITA (single ITA+RA) ( n=171). The t test, χ 2 test or Fisher exact test were used to compare the clinic characteristics between the two subgroups. The Kaplan-Meier curve was used to estimate the rate of late mortality, major adverse cardiac cerebrovascular event (MACCE), and target vessel revascularization (TVR). A Cox proportional hazards model was used to identify the independent prognosis factors of late mortality. Results:The overall mortality within 30 days postoperatively was 1.4%(3/208). The incidences of perioperative MACCE, re-operation for bleeding and deep sternal wound infection (DSWI) were 1.9%(4/208), 0.5%(1/208) and 1.4%(3/208), respectively. Perioperative myocardial infarction and TVR were not observed. There was no significant difference of 30-day mortality, MACCE, bleeding and DSWI between subgroup BITA and SITA+RA (all P>0.05). In a follow-up period of (5.4±2.8)years (range: 0.2 to 10.9 years), the incidence of all-cause mortality at 1-, 5- and 10-year was 2.3%, 3.4% and 6.9%, respectively. The incidence of MACCE was 3.9%,11.2% and 28.5%, respectively. The rate of TVR was 0.4%, 3.7% and 11.9%, respectively. Age>65 was an independent prognosis factor of late mortality ( HR=1.125, 95 % CI:1.050 to 1.205, P<0.01). Conclusions:Total arterial coronary bypass grafting is safe and achievable with proper patient selection and surgical strategies. It significantly decreases the risks of late mortality and repeated revascularization.

Objective:This study aims to investigate the efficacy and safety of chimeric antigen receptor (CAR) T-cell bridging allogeneic hematopoietic stem cell transplantation (allo-HSCT) in the treatment of recurrent and refractory acute B-lymphocytic leukemia (R/R B-ALL) .Methods:A total of 50 R/R B-ALL patients who underwent CAR T-scell therapy to bridge allo-HSCT in the First Affiliated Hospital of Soochow University from January 2017 to May 2019 were retrospectively analyzed. The overall survival (OS) rate, event-free survival (EFS) rate, cumulative recurrence rate (CIR) , and transplant-related mortality (TRM) of patients with different bone marrow minimal residual disease (MRD) levels were analyzed before and after CAR T-cell infusion and before allo-HSCT.Results:The response rate of CAR T-cell therapy and the incidence rate of severe cytokine release syndrome were 92% and 28% , respectively. During 55 infusions, no treatment-related deaths occurred in any of the patients. The median time of CAR T-cell infusion to allo-HSCT was 54 (26-232) days, the median follow-up time after CAR T-cell infusion was 637 (117-1097) days, and the 1-year OS and EFS rates were (80.0±5.7) % and (60.0±6.9) % . The 1-year CIR and TRM after allo-HSCT were (28.0±0.4) % and (8.0±0.2) % . After CAR T-cell infusion and before allo-HSCT, patients with bone marrow MRD<0.01% had a significantly longer EFS [ (70.0±7.2) % vs (20.0±12.6) % , P<0.001; (66.7±7.5) % vs (36.4±14.5) % , P=0.008]and lower CIR [ (25.0±0.5) % vs (70.0±2.6) % , P<0.001; (23.08±0.47) % vs (45.45±2.60) % , P=0.038]. Conclusion:CAR T-cell therapy bridging allo-HSCT is safe and effective for recurrent and refractory B-ALL.

Objective To investigate the monitoring significance of WT1 gene level in the prognosis of acute myeloid leukemia (AML) patients with normal karyotype after hematopoietic stem cell transplantation (HSCT). Methods The clinical data of 115 AML patients with normal karyotype who were treated with HSCT from July 2009 to March 2017 in the First Affiliated Hospital of Soochow University were retrospectively analyzed. The dynamic detection of bone marrow WT1 gene was carried out by using reverse transcription_polymerase chain reaction (RT_PCR). According to the relative expression level median of WT1 gene before transplantation, the whole patients were divided into the two groups (

Background The measurement of corneal Q value is essential for corneal refractive surgery and calculation of intraocular lens during cataract surgery.Topolyzer was often used for the measurement of Q value,and recently Topcon KR-1W and iTrace were applied in ophthalmology.However,whether the measured values are interchangeable is unclear.Objective This study was to assess the difference and consistency of corneal Q values measured by Topcon KR-1W,iTrace and Topolyzer.Methods Corneal Q values were measured on 100 right eyes of 100 healthy subjects under the approval of Ethic Committee of the Sixth Hospital Affiliated to Shanghai Jiaotong University and informed consent of each subject from November to December in 2014 with Topcon KR-1W,iTrace and Topolyzer.Three valid measurements were obtained for each device,and the average values from each device were calculated.The difference of the outcomes among the instruments was compared by repeated measures analysis of variance (ANOVA),and the consistency among the outcomes from different apparatus was analyzed by Bland-Altman plots.Results The mean corneal Q values were-0.184-±0.112,-0.117±0.167 and-0.269±0.117 from Topcon KR-1W,iTrace and Topolyzer,respectively,with a significant difference among them (P ＜ 0.001).The measured Q value by Topcon KR-1W was 0.085±0.010 larger than that by Topolyzer,and the Q values by iTrace was 0.152± 0.014 larger than that by Topolyzer,while the Q values obtained by Topcon KR-1W was 0.067±0.016 smaller than that by iTrace (all at P＜0.05).The 95％ confidence interval of the values between Topcon KR-1W and iTrace,Topcon KR-1W and Topolyzer,iTrace and Topolyzer were-0.106 to-0.028,0.060 to 0.109 and 0.118 to 0.186,respectively.Bland-Altman plots showed that 6％,6％ and 5％ values were outside of 95％ agreement of limit (LoA) between Topcon KR-1W and iTrace,iTrace and Topolyzer or KR-1W and Topolyzer,respectively,with the maximal differences of 0.28,0.43 and 0.38.Conclusions Corneal Q values measured by Topcon KR-1W and iTrace are larger than those measured by Topolyzer.Due to the poor agreements among the corneal Q values by the 3 kinds of devices,they are not interchangeable in clinical applications for the measurement of corneal Q value.

OBJECTIVETo study clinical characteristics of refractory or relapsed DNMT3A⁺ cytogenetically normal acute myeloid leukemia（CN-AML）patients, and to explore the overall response rate（ORR）and side effects of these patients followed the therapy including decitabine with CAG or CAGlike regimen.

METHODSIn this study we retrospectively analyzed 53 refractory or relapsed CN- AML patients receiving the therapy including decitabine combined with CAG and CAG- like regimen in our center from April 2011 to October 2014. The clinical characteristics and ORR were further analyzed. Based on gene mutations, these patients could be divided into 2 groups: DNMT3A⁺ AML patients（n=24）and DNMT3A- AML patients（n=29）.

RESULTSThe median age of DNMT3A⁺AML patients was 46 years old, higher white blood cells and bone marrow blasts were observed in DNMT3A+ AML group. The ORR and complete response（CR）rate of DNMT3A+ group were 62.50% and 54.17%, respectively. No differences were observed in ORR and CR rates（P>0.05）between these two groups. DNMT3A⁺/FLT3-ITD⁺ CN-AML patients（n=14）had higher ORR and CR rates than DNMT3A-/FLT3-ITD⁺CN- AML patients（n=15）（P= 0.040 and 0.042, respectively）. The one- year overall survival （OS） of DNMT3A⁺ AML group and DNMT3A- AML group were 59.58% , 54.09% , no differences were observed （P=0.438）. 25 patients received further therapy of allo-HSCT, the one-year OS of DNMT3A⁺ CN-AML was 87.50% and one-year disease free survival（DFS）was 72.73%, while the one- year OS was 61.54% and one- year DFS was 58.02% in DNMT3A⁻ group. No differences were observed between 2 groups （P=0.456, 0.217）.

CONCLUSIONDecitabine combined with CAG or CAG-like regimen was an effective and safe treatment for refractory or relapsed CN- AML patients. Compared to DNMT3A⁻/FLT3- ITD⁺ CN- AML patients, DNMT3A⁺/ FLT3-ITD⁺ CN-AML patients had higher ORR and CR rates. Decitabine bridged hematopoietic stem cells transplant could likely improve the survival of refractory or relapsed CN-AML patients.
