Endoscopic Submucosal Dissection: A Safe and Effective Alternative to Surgical Intervention for Esophageal Hemangioma.

BACKGROUND: Hemangiomas represent 3% of all benign esophageal tumors. Conventional esophagectomy is the standard treatment with its invasive nature and possible surgical complications. Now, less invasive techniques are used with better results. Endoscopic submucosal dissection (ESD) is one of the novel noninvasive methods used for en bloc removal of tumors. No available data about the use of ESD in removing esophageal hemangioma. Here, we studied the validity and safety of ESD as a minimally invasive procedure to remove esophageal hemangioma. METHODS: Three patients were diagnosed with esophageal hemangioma and underwent ESD with en bloc resection. Endoscopic ultrasound (EUS) was performed before ESD to better evaluate the layer of origin and vascularity and guard against perforation. Patients were followed up postintervention to document possible complications. RESULTS: Among the 3 studied patients, one presented with chronic abdominal pain, the second was complaining of dysphagia, and the third patient was diagnosed accidentally. Pathology reports confirmed the diagnosis of hemangiomas in all cases with no atypia and complete removal of the lesions. No complications were reported during the procedure or over the follow-up period. CONCLUSIONS: ESD is a proper, minimally invasive method with good en bloc resection that can be used in cases of esophageal hemangiomas.

Clinical phenotype characteristics and genetic analysis in children with nephronophthisis and related syndromes caused by different gene mutations / 中国当代儿科杂志

OBJECTIVES@#To improve the understanding of the clinical phenotypes and genetic characteristics of nephronophthisis (NPHP) and related syndromes in children.@*METHODS@#A retrospective analysis was performed on the medical data of eight children with NPHP and related syndromes who were diagnosed and treated in the Department of Pediatrics of the Second Hospital of Hebei Medical University, from January 2018 to November 2022. The clinical characteristics and genetic testing results were analyzed.@*RESULTS@#Among these eight children, there were five boys and three girls, with an age of onset ranging from 15 months to 12 years. All 8 children exhibited different degrees of renal function abnormalities when they attended the hospital. Among the eight children, two had the initial symptom of delayed development, two had the initial symptom of anemia, and two were found to have abnormal renal function during physical examination. The extrarenal manifestations included cardiovascular abnormalities in two children, skeletal dysplasia in two children, liver dysfunction in one child, retinitis pigmentosa in one child, and visceral translocation in one child. All eight children had renal structural changes on ultrasound, and four children had mild to moderate proteinuria based on routine urine test. Of all eight children, five had NPHP1 gene mutations and one each had a gene mutation in the NPHP3, IFT140, and TTC21B genes, and four new mutation sites were discovered.@*CONCLUSIONS@#Children with NPHP and related syndromes often have the initial symptom of delayed development or anemia, and some children also have extrarenal manifestations. NPHP and related syndromes should be considered for children with unexplained renal dysfunction, and high-throughput sequencing may help to make a confirmed diagnosis.

Efficacy comparison of extracorporeal membrane oxygenation and ventilation therapy in the treatment of severe blast lung injury / 中华创伤杂志

Objective:To compare the clinical efficacy of extracorporeal membrane oxygenation (ECMO) and ventilation therapy in the treatment of severe blast lung injury.Methods:A retrospective cohort study was conducted to analyze the clinical data of 37 patients with severe blast lung injury admitted to 909th Hospital of Joint Logistics Support Force (Affiliated Dongnan Hospital of Xianmen University Medical College) from January 2000 to December 2021, including 23 males and 14 females; aged 26-50 years [(36.3±11.1)years]. The chest abbreviated injury score (AIS) was 3-5 points. In all, 16 patients were treated with ECMO from January 2017 to December 2021 (ECMO group) and 21 with ventilator from January 2000 to December 2016 (ventilator group). Blood gas analysis indexes [arterial pH, partial pressure of carbon dioxide (PaCO 2), partial pressure of oxygen (PaO 2), blood lactate (Lac)] and hemodynamics indexes [central venous pressure (CVP), cardiac output index (CI), pulmonary arterial systolic pressure (PASP), pulmonary capillary wedge pressure (PAWP)] were compared in the two groups at 30 minutes before treatment and at 2, 4, 6 hours after treatment. The mechanical ventilation time, ICU length of stay, acute physiology and chronic health evaluation II (APACHE II) score and mortality were measured at 7 days after treatment. Results:All patients were followed up for 24-48 months [(33.6±8.2)months]. The blood gas analysis and hemodynamic indexes were significantly improved in the two groups at 2, 4, 6 hours after treatment when compared with those at 30 minutes before treatment (all P<0.05), and the improvements were still statistically significant in ECMO group at 4, 6 hours after treatment when compared with those at 2 hours after treatment (all P<0.05), while not in ventilator group (all P>0.05). There was no significant difference in blood gas analysis indexes or hemodynamic indexes between the two groups at 30 minutes before treatment (all P>0.05). After treatment for 2, 4, 6 hours, blood gas analysis indexes and hemodynamic indexes in ECMO group were statistically different from those in ventilator group (all P<0.05). After treatment for 7 days, the mechanical ventilation time, ICU length of stay, APACHE II score and mortality were (3.2±1.2)days, (5.4±1.3)days, (14.1±3.3)points and 12.5% (2/16) in ECMO group, significantly different from (5.1±1.6)days, (7.6±1.6)days, (10.2±2.6)days and 28.6% (6/21) in ventilator group (all P<0.05). Conclusion:For severe blast lung injury, ECMO can attain rapid and continuous improvement of refractory hypoxemia and dyspnea, shorten the duration of mechanical ventilation and ICU length of stay and reduce the mortality rate when compared with ventilator therapy.

Research Progress of Small Molecule Anti-angiogenic Drugs in Non-small Cell Lung Cancer / 中国肺癌杂志

Lung cancer is one of the cancers with the highest incidence in the world, and there is no standard treatment plan after second-line progression. Tumor angiogenesis has now been identified as an important therapeutic target for malignant tumors. Small molecule multi-target vascular kinase inhibitors can inhibit tumor angiogenesis by inhibiting angiogenesis-related signal pathways. At present, a lot of clinical trials of small molecule anti-angiogenic drugs for the treatment of non-small cell lung cancer (NSCLC) have been carried out, and some vascular endothelial growth factor receptor-tyrosine kinase inhibitors (VEGFR-TKIs) have been approved for the treatment of advanced NSCLC. Based on the development status of multiple small molecule anti-angiogenic drugs at home and abroad for the treatment of NSCLC, this article summarizes the efficacy and safety studies of multiple VEGFR-TKIs and fibroblast growth factor receptor (FGFR)-TKI single agents or combination treatments [including combined with chemotherapy, epidermal growth factor receptor (EGFR)-TKIs, immunotherapy, and radiotherapy, etc.] for NSCLC, and at the same time discussed the possible existence of VEGFR-TKIs drug resistance mechanisms and efficacy predictors, etc., and prospect the future development trend and potential problems of anti-vascular treatment of NSCLC, and provide new ideas for the follow-up precision and individualized treatment of lung cancer.

Association between autophagy and systemic juvenile idiopathic arthritis and related mechanism: a preliminary study / 中国当代儿科杂志

OBJECTIVE@#To study the role of autophagy in the development of systemic juvenile idiopathic arthritis (sJIA) by analyzing the expression of microtubule-associated protein 1 light chain 3-II (LC3-II), myeloid differentiation factor 88 (MyD88), and suppressor of T-cell receptor signaling 1 (STS-1) in peripheral blood lymphocytes of children with sJIA.@*METHODS@#A total of 26 children with sJIA were enrolled as the sJIA group, and 26 healthy children were enrolled as the control group. Western blot was used to measure the protein expression of LC3-II, STS-1, and MyD88 in peripheral blood lymphocytes. Immunofluorescence assay was used to measure the expression of LC3-II in the cytoplasm of lymphocytes. Pearson correlation analysis was used to assess the correlation between indices.@*RESULTS@#Compared with the control group, the sJIA group had significant increases in the expression of LC3-II, STS-1, and MyD88 (P<0.05). In the sJIA group, the expression of LC3-II was positively correlated with that of MyD88 (r=0.478, P<0.05), and the expression of STS-1 was also positively correlated with that of MyD88 (r=0.817, P<0.05).@*CONCLUSIONS@#There is high expression of LC3-II in peripheral blood lymphocytes of children with sJIA, suggesting that the development of sJIA may be associated with excessive expression of autophagy. STS-1 may induce autophagy by activating some signaling pathways, and MyD88 may participate in autophagy through the Toll-like receptor signaling pathway.

Objective assessment of competence of gastrointestinal endoscopy trainees by a virtual reality simulator / 中华消化内镜杂志

Objective To investigate the potential effectiveness of a computer-based gastrointestinal (GI) endoscopy simulator in assessing the competence of GI endoscopy trainees.Methods Fifty trainees working in the endoscopy center of General Hospital of Chinese PLA between February 2009 and October 2011 were enrolled.These participants were divided into four groups based on their prior endoscopic experience:novices (no endoscopy experience),intermediate experienced (≤200 colonoscopies or ≤ 500 gastroscopies),experienced (201-1000 colonoscopies or 501-2000 gastroscopies),and experts (＞ 1000 colonoscopies or ＞ 2000 gastroscopies).Assessment of endoscopic skills was performed during a hand-eye coordination task (Endo Bubble level 1) and was based on parameters measured by the computer system including time to finish,average time between two bubbles,number of times wall touched.Results When GI trainees were categorized by their prior gastroscopy number,the time to finish of each group were (302.43 ± 108.96)s,(188.00 ± 59.88) s,135.00 (40.00) s,150.00 (69.00) s,and the average time between two bubbles were (14.29 ± 5.47) s,(8.82 ± 3.28) s,6.00 (2.00) s,7.00 (4.00) s,respectively.Pairwise comparison showed that except experienced and experts groups (P ＞ 0.05),there were significantly differences between remaining groups (P ＜0.01).However,based on the colonoscopic experiences,the time to finish of each group were 220.00(91.00)s,127.00(28.25)s,155.50(81.00)s,150.00(58.50)s,respectively,which were significantly different between each two groups (P ＜ 0.01).Average time between two bubbles of each group were 10.00 (4.00) s,5.50 (1.50) s,7.00 (3.75) s,7.00 (3.50) s,respectively,which were found significantly different among whole groups (P ＜ 0.05 or P ＜ 0.01),but there were no differences between novice and experienced trainees and between intermediate experienced and experts groups.In contrast,the number of wall-touch was insufficient for assessment.Except the significant difference between novice and experienced group (P ＜ 0.05) as categorized by gastroscopy experience,there were no values to differentiate the trainees of different practical competence on gastroscopy or colonoscopy.Conclusion The parameter,time to finish,during a hand-eye coordination task using a virtual reality simulator might be able to differentiate the competence of operators,which was used prior to training in real-life endoscopy,but lack of accurate discriminatory function between experienced and experts.

Protective effect of salidroside pretreatment on rabbit heart after limb ischemia/reperfusion / 心血管康复医学杂志

Objective: To observe the protective effect of salidroside pretreatment on rabbit heart after limb ischemia/reperfusion (I/R). Methods: A total of 24 New Zealand rabbits were randomly and equally divided into sham operation group, I/R + placebo group （I/R group）and salidroside pretreatment group（salidroside group）. Before establishment of rabbit models of limb I/R, salidroside group received salidroside injection via ear marginal vein, and I/R group received saline injection, once a day for three days. After model establishment, echocardiography was used to evaluate rabbit cardiac function of each group 4h after reperfusion, including left ventricular end-systolic dimension (LVESd), left ventricular end-diastolic dimension (LVEDd), left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (FS). Blood sample was taken to measure serum cardiac troponin I (cTnI) and tumor necrosis factor (TNF)-α. Some ventricular tissue homogenates were taken to measure levels of superoxide dismutase (SOD) and malonyl diadehyde (MDA). Then heart sample was taken to receive pathological examination. Results: Compared with I/R group 4h after reperfusion, there were significant decrease in LVESd [(0.69±0.07) mm vs. (0.62±0.05) mm] and significant increase in LVEF [(64.6±3.4) % vs. (72.1±3.6) %], FS [(34.2±3.2) % vs. (41.7±3.4) %] (P0.05). Compared with I/R group, there were significant decrease in cTnI [(5.24±0.34) μg/ml vs. (1.06±0.12) μg/ml], MDA [(8.92±2.18) μmol/L vs. (6.79±1.43) μmol/L] and TNF-α [(37.43±10.02) pg/ L vs. (19.73±6.31) pg/ L], and significant increase in SOD level [(16.61±3.75) U/ml vs. (22.26±4.73) U/ml] in salidroside group (P<0.05 all). Pathological results indicated that injury degree in salidroside group was significantly attenuated than that of I/R group. Conclusion: Salidroside pretreatment could protect cardiac function and relieve rabbit cardiac injury after limb ischemia/reperfusion.

Treatment of obesity by endoscopic gastric intramural injection of botulinum toxin A: a randomized clinical trial.

BACKGROUND/AIMS: Botulinum toxin A (BTX-A) is an inhibitor of muscular contractions in both striated and smooth muscle. The purpose of this study was to observe the safety and efficacy of endoscopic injections of BTX-A into the gastric wall in obese patients. METHODOLOGY: Twenty obese patients (BMI >28 kg/m2) were randomized into two groups: Group 1 (200 U BTX-A) and Group 2 (300 U BTX-A). For each patient, 20 puncture sites were selected into the gastric wall. Body weights and BMIs were recorded and gastric emptying times were determined before treatment and 1, 4 and 12 weeks after treatment. Blood samples for cholesterol, triglycerides, insulin, leptin, motilin, peptide tyrosine (PYY) and ghrelin levels were obtained before treatment and 1, 4 and 12 weeks after treatment. RESULTS: Nineteen patients completed the follow-up. Both groups showed significant body weight and BMI decrease (p<0.05) with decreased TG levels. The gastric emptying times were longer than those before treatment in both groups, especially at the 1-week point (p<0.05). A significant decrease in fasting ghrelin levels in all 19 obese patients was found after BTX-A administration 4 weeks later, and PYY levels in all 19 patients decreased, especially at the 12-week point. No severe complications were observed. CONCLUSIONS: Endoscopic multi-punctures of BTX-A including fundic injections may decrease body weight and BMI by delaying the gastric emptying time. The effect of BTX-A on ghrelin levels may also be involved in the reduction of appetite.
