Objective:To investigate the clinical value of early gastroscopy for patients with hypopharyngeal cancer.Methods:A total of 231 cases of hypopharyngeal cancer diagnosed and treated in the First Affiliated Hospital of Xiamen University from January 2010 to December 2014 were included in the retrospective analysis. The 5-year survival rate of hypopharyngeal cancer and patients accompanied with synchronous esophageal cancer (including early and advanced esophageal cancer), as well as the detection rate of synchronous esophageal cancer by gastroscopy and systemic PET-CT examination were statistically analyzed.Results:The 5-year survival rate of hypopharyngeal cancer was 38.96% (90/231). The 5-year survival rates of 62 patients accompanied with synchronous esophageal cancer and 169 patients without were 27.42% (17/62) and 43.20% (73/169), respectively, with statistic difference ( χ2=4.747, P=0.029). The 5-year survival rate of 49 patients accompanied with synchronous early esophageal cancer was 30.69% (17/49). Among the 13 patients with synchronous progressive esophageal cancer, none had a survival period of 5 years, which was significantly different compared with the patients with synchronous early esophageal cancer ( P=0.013). The detection rates of synchronous esophageal carcinoma by gastroscopy and by systemic PET-CT were 26.84% (62/231) and 14.29% (33/231), respectively, with statistic difference ( χ2=11.14, P<0.01). The detection rates of synchronous early esophageal carcinoma by gastroscopy and by systemic PET-CT were 21.21% (49/231) and 8.66% (20/231), respectively, and the difference was also statistically significant ( χ2=14.328, P<0.01). Conclusion:Hypopharyngeal cancer accompanied with synchronous esophageal cancer is of high risk, which affects the survival rate of patients. Early gastroscopy in hypopharyngeal cancer patients can significantly improve the detection rate of synchronous esophageal cancer, which helps to design individualized regimen to improve the survival rate of patients.

Objective To summarize the technique and clinical experience of hybrid procedure under cardiopulmonary bypass (CPB) in children with muscular ventricular septal defect (mVSD). Methods From January 2006 to June 2010, 45 cases of mVSD underwent hybrid procedure with CPB. mVSDs were closed with devices under direct vision in 45 cases. Of them, there were 20 males and 25 females. They ranged from 52 days to 12 years [mean (2.05 ±2.48) year] in age and from 3 to 30 kg [(11.93 ±7.70)kg] in body weight. Preoperatively, most of children were highly susceptible to respiratory tract infections. The hybrid approach was used in all patients with CPB under the guidance of transesophageal echocardiography (TEE). The diameter of mVSDs ranged from 2 to 7 mm under TEE. Of 45 cases, 40 patients had increased rates of pulmonary blood flow. 29 patients had left axis deviation and 12 cases had sinus arrhythmia on electrocardiography (ECG). 19 had other congenital heart lesions, including transposition of great arteries in 1 case, tetralogy of Fallot in 2, pulmonary artery stenosis in 3, patent ductus arteriosus in 6, atrial septal defects in 6) and aorta coactation in 1. The quantity of VSDs were from 1 to 7 (single, in 7; two, in 24 case; three, in 8 case; four, in 5 case and seven, in lease. 37 patients were combined with pulmonary hypertension in our cohort. 38 patients with another large VSD and 19 with other congenital heart lesions were required surgical repair at sometime. Results The hybrid procedures were undertaken in all 45 cases of this cohort. All cases were successful and no deaths occurred during operation. A total of 48 devices were implanted in 45 patients, including single devices in 42 cases (device size ranged from 4 to 10 mm) and two devices in 3 cases (device size ranged from 4 -7 mm). The average time on CPB was (58.28 ±20.70) min , while aortic crossclamp time was(34. 94 ± 14.75) min. In addition, the time on mechanical ventilation postoperatively ranged from 2 hours to 6 days. Compared to the older children, 20 infante aged less than 8 monhad a significant difference in cardiac function in the early postoperative period. One infant was given up treatment because of serious infection. Anather cases recovered with the use of supportive treatment, such as using vasoactive agents, digoxin, inhaling nitric oxide, diuresis, and so on. The enteric-coated aspirin was given at dose of 5 mg ? kg -1. day -1 for a period of 3 to 6 months as usual postoperatively. All patients attended follow-up at 1 week, 1 month, 3 months, 6 months, 1 year and 2 years post-procedure. No major complications were encountered during this period. All cases were no instance of migration of any of the devices, residual shunt, aortic regurgitation, atrioventricular valve dysfunction, Ⅲo atrial-ventricular conduction block, new arrhythmia, and so on. There are no death in long-term follow-up. Conclusion Hybrid procedure is safe and effective for the closure of congenital heart defects in children.

Objective:To investigate the metabolic disorder of gut microbiota and short-chain fatty acids (SCFAs) in patients with hypertensive intracerebral hemorrhage and their correlations with the poor outcomes.Methods:Thirty-eight patients with hypertensive intracerebral hemorrhage within 7 d of onset and 32 healthy controls were enrolled prospectively. Fecal samples were collected for 16S rRNA sequencing and SCFAs levels detection. The outcome was evaluated by the modified Rankin Scale at 90 d after the onset, and >2 points were defined as a poor outcome. Multivariate logistic regression model was used to determine the correlations between the gut microbiota and the fecal SCFAs levels and outcomes. Results:The gut microbiota of patients with hypertensive intracerebral hemorrhage was significantly different from that of healthy control group. It is manifested as a decrease in α diversity, a difference in β diversity, an increase in the abundance of potential undesirable bacteria, a decrease in the abundance of common SCFA-producing bacteria and a decrease in the fecal SCFAs levels. In patients with hypertensive intracerebral hemorrhage, compared with the good outcome group, the α diversity of the gut microbiota, the abundance of SCFA-producing bacteria such as Lacetospirillum and Bacteroides, and the total SCFAs, acetic acid and propionic acid levels decreased in the poor outcome group. Multivariate logistic regression analysis showed that after adjusting for potential confounding factors, the decrease of fecal SCFAs levels after log2 conversion was significantly and independently correlated with the poor outcomes. Conclusion:Patients with hypertensive intracerebral hemorrhage have gut microbiota and SCFAs metabolic disorder, the latter is significantly correlated with the poor outcomes. Gut microbiota and SCFAs may become an outcome marker and treatment target for patients with hypertensive intracerebral hemorrhage

Objective:To study the efficacy of dental floss traction-assisted endoscopic submucosal dissection (ESD) for gastric angle mucosal lesions.Methods:Data of 127 patients with gastric angle mucosal lesions admitted to the endoscopic center of the First Affiliated Hospital of Xiamen University from January 2015 to December 2018 were retrospectively analyzed. According to the surgical methods, patients were divided into the dental floss traction-assisted ESD group (the traction group, n=51) and the traditional ESD group (the traditional group, n=76). The 41 fibrosis cases were further divided into the traction group (n=23) and the traditional group (n=18). The operation time, en block resection rate, curative resection rate and the incidence of adverse events such as bleeding, muscle layer injury and perforation were compared between the two groups.Results:There was no significant difference in age, sex, lesion size or morphology between the traction group and the traditional group ( P > 0.05). The operation time of the traction group was significantly shorter than that of the traditional group (65.4±36.5 min VS 103.5±43.2 min, P=0.012). The en block resection rate was higher in the traction group [100.00% (51/51) VS 90.79% (69/76), P=0.026], and the curative resection rate was higher too [94.12% (48/51) VS 81.58% (62/76), P=0.042]. The incidences of muscular layer damage [5.88% (3/51) VS 25.00% (19/76), P=0.010] and intraoperative bleeding [47.06% (24/51)VS 82.89% (63/76), P=0.010] were lower in the traction group. Perforation occurred in two patients (2.63%) of fibrosis in the traditional group; no perforation occurred in the traction group. There was no significant difference in the perforation incidence ( P=0.243). In the cases of fibrosis, the operation time of the traction group was significantly shorter compared with that of the traditional group (81.4±29.3 min VS 119.3±37.6 min, P=0.010). The en block resection rate and curative resection rate were also higher in the traction group [100.00% (23/23) VS 72.22% (13/18), P=0.007; 95.65% (22/23) VS 72.22% (13/18), P=0.035]. The incidences of muscular layer damage [8.70% (2/23) VS 72.22% (13/18), P=0.001] and intraoperative bleeding [78.26% (18/23) VS 100.00% (18/18), P=0.035] were lower in the traction group. Conclusion:The dental floss traction-assisted ESD is safe and effective for gastric angle mucosal lesions and fibrotic lesions, with shorter operation time, higher curative resection rate and lower incidence of adverse events.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.
