Objective:To analyze the clinical features and genetic characteristics of a patient with Shwachman-Diamond syndrome (SDS) due to compound heterozygous variants of SBDS gene.Methods:A female child with SDS who was admitted to the Children's Hospital Affiliated to Zhengzhou University in February 2022 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and her elder sister and parents were collected and subjected to whole exome sequencing (WES). Candidate variant was verified by Sanger sequencing.Results:The child, a 1-year-and-1-month-old girl, had mainly manifested with diarrhea, hematochezia, growth retardation and malnutrition, along with increased transaminases and decreased neutrophils and hemoglobin. The anteroposterior X-ray of her left wrist indicated significantly delayed bone age. Colonoscopy revealed that her colorectal mucosa was erosive with oily food residues attached to the intestinal lumen. Genetic testing revealed that she has harbored c. 258+ 2T>C and c. 100A>G compound heterozygous variants of the SBDS gene. The c. 258+ 2T>C variant has derived from her father and known to be pathogenic, whilst the other has derived from her mother. Based on the guidelines from the American College of Medical Genetics and Genomics, the c. 100A>G variant was classified as likely pathogenic (PM1+ PM2_Supporting+ PM3+ PM5+ PP3). Conclusion:The compound heterozygous variants of c. 258+ 2T>C and c. 100A>G probably underlay the SDS in this child. For children with refractory diarrhea, liver damage and growth retardation, SDS should be suspected, and genetic testing can facilitate the diagnosis and treatment.

Objective To investigate the expression of serum miR-133a-3p and miR-324-3p in patients with persistent atrial fibrillation and their relationship with recurrence of atrial fibrillation after radiofrequency ablation.Methods A total of 180 patients with persistent atrial fibrillation(persistent atrial fibrillation group)who were hospitalized in Cangzhou City People's Hospital from July 2019 to July 2022 and received radiofrequency ablation were collected as research objects.According to whether atrial fibrillation recurred,they were assigned into a non recurrence group(n=116)and a recurrence group(n=64).Meanwhile,another 180 healthy individuals who underwent physical examination at the hospital were regarded as the control group.The expression levels of serum miR-133a-3p and miR-324-3p of each group were compared.Multivariate Logistic regression was applied to analyze the factors influencing the recurrence of persistent atrial fibrillation after radiofrequency ablation,and ROC curve analysis was applied to analyze the predictive value of serum miR-133a-3p and miR-324-3p levels for the recurrence of atrial fibrillation in patients with persistent atrial fibrillation after radiofrequency ablation.Results Compared with the control group,the levels of serum miR-133a-3p(0.76±0.25)and miR-324-3p(0.68±0.21)in the persistent atrial fibrillation group were lower than the control group(1.03±0.32,1.05±0.30),and the differences were statistically significant(t=8.921,13.556,all P<0.05).The serum levels of miR-133a-3p(0.58±0.19)and miR-324-3p(0.50±0.16)in the recurrent group were obviously lower than those in the non recurrent group(0.86±0.27,0.78±0.25),and the differences were statistically significant(t=7.349,8.087,all P<0.05).Multivariate Logistic regression analysis showed that serum miR-133a-3p[OR(95%CI):0.673(0.534～0.848)]and miR-324-3p[OR(95%CI):0.756(0.629～0.909)]were protective factors for atrial fibrillation recurrence after radiofrequency ablation in patients with persistent atrial fibrillation,while heart rate[OR(95%CI):2.143(1.265～3.631)]and LAD[OR(95%CI):1.756(1.159～2.661)]were independent risk factors for atrial fibrillation recurrence after radiofrequency ablation in patients with persistent atrial fibrillation(all P<0.05).The AUC of the combination of miR-133a-3p and miR-324-3p in predicting atrial fibrillation recurrence after radiofrequency ablation in patients with persistent atrial fibrillation was 0.901,with the sensitivity and specificity were 82.81%and 86.21%,respectively,which was better than those of their respective prediction alone(Z=4.210,2.804,all P<0.05).Conclusion The expressions of serum miR-133a-3p and miR-324-3p in patients with persistent atrial fibrillation are reduced,and the combination of the two has a good reference value in predicting the recurrence of atrial fibrillation in patients with persistent atrial fibrillation after radiofrequency ablation.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.

The application of special laparoscopic techniques is focused on the GIST of cardia to preserve the function of the cardia.

Objective To investigate the independent risk factors for acute severe cholangitis and related protective factors, and to construct a risk prediction scoring model for acute severe cholangitis. Methods A retrospective analysis was performed for the clinical data of 381 patients with acute cholangitis who were admitted to Department of Hepatobiliary Surgery, The 940th Hospital of Joint Logistics Support Force of Chinese People's Liberation Army, from January 2016 to July 2021, among whom there were 273 patients with non-severe cholangitis and 108 patients with severe cholangitis. Univariate and multivariate logistic regression analyses were used to screen out the independent risk factors for acute severe cholangitis and related protective factors, and then a logistic regression model was established. The receiver operating characteristic (ROC) curve was used to evaluate the discriminatory ability of the model, the calibration curve was used to evaluate the prediction accuracy of the model, and decision curve analysis (DCA) was used to evaluate the clinical value of the model. Moreover, the enhanced Bootstrap method was used to perform internal validation of the model and evaluate the performance of the model in internal validation. The model was visualized by the construction of Web calculator, nomogram, and scoring system. The two-independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. Results The univariate and multivariate logistic regression analyses showed that total bilirubin (TBil) (odds ratio [ OR ]=1.014, 95% confidence interval [ CI ]: 1.009-1.020, P < 0.001), percentage of neutrophils ( OR =1.128, 95% CI : 1.088-1.175, P < 0.001), and age ( OR =1.053, 95% CI : 1.027-1.082, P < 0.001) were independent risk factors, and albumin (Alb) ( OR =0.871, 95% CI : 0.817-0.924, P < 0.001) was a protective factor. The above independent risk factors and protective factor were included in the logistic regression analysis for model fitting, and the predictive model obtained had an area under the ROC curve (AUC) of 0.925 (95% CI : 0.897-0.952), with a specificity of 0.817 and a sensitivity of 0.935 at the optimal cut-off value of 0.245. The calibration curve showed that the predicted probability of the model was approximately equal to the actual probability, with a Brier value of 0.098, and the decision curve analysis showed that the model had a higher net income within the threshold probability interval of 0.1-0.9. Internal validation showed an AUC internal validation of 0.915 and a Brier value internal verification of 0.106. Conclusion TBil, percentage of neutrophils, and age are independent risk factors for acute severe cholangitis, while Alb is a protective factor. The established risk prediction scoring model has good discriminatory ability, calibration, and clinical value and can identify patients with acute severe cholangitis at an early stage, which provides a reference for subsequent diagnosis and treatment.

Objective:To evaluate radiofrequency ablation-assisted liver resection on early recurrence of hepatocellular carcinoma(HCC) with microvascular invasion (MVI).Methods:A total of 82 HCC patients from Jun 2015 to Jun 2020 were divided into assisted group ( n=41) and control group ( n=41) after local hepatectomy.And by pathology,both groups were further substratified into with or without MVI subgroups. Results:There was no statistically significant difference in the baseline data between two groups,nor there was difference in recurrence-free survival rate between the two groups ( χ 2=0.177, P=0.674). However, by subgroup analysis, the recurrence-free survival rate of ablation assisted group was higher than that of the simple local hepatectomy group among MVI positive patients ( χ 2=5.096, P = 0.024).Multivariate analysis showed that only tumor diameter ( HR=1.32, 95% CI: 1.02-1.72, P=0.036) was an independent risk factor for local recurrence at the incisal margin, while mode of operation ( HR=0.15 ,95% CI: 0.04-0.52 ,P=0.003) and MVI ( HR=8.65 ,95% CI: 2.19-34.19 ,P=0.002) were independent risk factors for intrahepatic distant metastasis. Conclusion:Local hepatectomy assisted by intraoperative radiofrequency ablation on hepatic cross section could effectively reduce the postoperative early recurrence rate for hepatocellular carcinoma patients with MVI.

Objective:To investigate the clinical characteristics, endoscopic features and management of acquired tracheoesophageal fistula (TEF) by esophageal foreign bodies in children.Methods:The clinical data and follow-up data of 21 children with acquired TEF who were treated in Children′s Hospital Affiliated to Zhengzhou University from January 2008 to January 2019 were retrospectively analyzed.Results:A total of 21 cases with esophageal foreign bodies were button batteries, irregular iron sheets, game coins, jujube seed, animal bone sheets, and fish thorn.The statistical results suggested that the cases of button batteries were 7 cases (33.33%), 4 cases of jujube pit (19.05%), 3 cases of irregular iron (14.29%) and 3 cases of animal bone (14.29%), 2 cases of game coin (9.52%), 2 cases of fish thorn (9.52%). All foreign bodies were removed by endoscopy.Esophageal perforation with TEF was discovered in 17 cases (80.95%) during the operation.Esophageal perforation with TEF was found in 4 cases (19.05%) within 2 week after the operation, and no death occurred.A total of 13 case fistula size ≤5 mm (61.90%), 4 case fistula size>5 mm and ≤10 mm (19.05%) and 4 case fistula size >10 mm (19.05%). The treatment methods included gastrointestinal decompression and nasojejunal nutrition tube support in 10 cases (47.61%), gastrostomy and jejunostomy in 4 cases (19.05%), surgical repair in 4 cases (19.05%) and endoscopic titanium clip suture in 3 cases (14.29%). Five cases (23.81%) were healed in 3 months, 6 cases (28.57%) in 5 months, 4 cases (19.05%) in 8 months, and 2 cases (9.52%) in 12 months.Conclusions:Acquired TEF in children are mostly caused by special foreign bodies embedded in the esophagus, and endoscopic management is effective for fistulas with less trauma.Appropriate operation and intervention should be taken as early as possible.

Objective:To analyze the clinical characteristics, endoscopic manifestations, complications and related risk factors of button battery ingestion in 58 children, thus providing the basis for clinical diagnosis and treatment.Methods:The medical data of 58 children with button battery ingestion were collected and researched at Children′s Hospital Affiliated to Zhengzhou University from September 2015 to September 2020.The demographic information, battery impaction location, duration, symptoms, mucosal injury level, battery size, treatment, complications and follow-up results were analyzed.Results:The average age of the patients with button battery ingestion was (25.7±15.4)months, including 40 boys(68.9%). The average retention time of the battery in digestive tract was 13.8(2, 96) h. Vomiting, salivation, dysphagia, cough and fever were the common chief complaints.There were 29(50.0%) cases of grade I mucosal injury, as well as 14(24.1%) cases, 10(17.2%) cases and 10(17.2%) cases for grade Ⅱ, grade Ⅲ and grade Ⅳ, respectively.Additionally, common complications included esophageal stenosis, esophageal perforation and esophageal-tracheal fistula.Logistic regression analysis showed that location(esophagus) and diameter(≥15 mm) of battery incarceration were important predictors of complications.Conclusion:The degree of mucosal damage is associated with the diameter and impaction location of battery.The button battery embedded in the esophagus is prone to complications, while the ones retained in the stomach were not vulnerable to serious complications.Endoscopy and other related examinations should be performed again in 1 to 3 weeks after the button removal to determine the outcome of complications and to intervene in time.
