OBJECTIVES: To evaluate the effectiveness of single-balloon and double-balloon enteroscopy in diagnosing pediatric small bowel diseases and assess the diagnostic efficacy of computed tomography enterography (CTE) for small bowel diseases using enteroscopy as the reference standard. METHODS: Clinical data from 576 children who underwent enteroscopy at Hunan Children's Hospital between January 2017 and December 2023 were retrospectively collected. The children were categorized based on enteroscopy type into the single-balloon enteroscopy (SBE) group (n=457) and double-balloon enteroscopy (DBE) group (n=119), and the clinical data were compared between the two groups. The sensitivity and specificity of CTE for diagnosing small bowel diseases were evaluated using enteroscopy results as the standard. RESULTS: Among the 576 children, small bowel lesions were detected by enteroscopy in 274 children (47.6%).There was no significant difference in lesion detection rates or complication rates between the SBE and DBE groups (P>0.05), but the DBE group had deeper insertion, longer procedure time, and higher complete small bowel examination rate (P<0.05). The complication rate during enteroscopy was 4.3% (25/576), with 18 cases (3.1%) of mild complications and 7 cases (1.2%) of severe complications, which improved with symptomatic treatment, surgical, or endoscopic intervention. Among the 412 children who underwent CTE, the sensitivity and specificity for diagnosing small bowel diseases were 44.4% and 71.3%, respectively. CONCLUSIONS SBE and DBE have similar diagnostic efficacy for pediatric small bowel diseases, but DBE is preferred for suspected deep small bowel lesions and comprehensive small bowel examination. Enteroscopy in children demonstrates relatively good overall safety. CTE demonstrates relatively low sensitivity but comparatively high specificity for diagnosing small bowel diseases.

Colorectal cancer (CRC) poses a severe global health challenge with high incidence and mortality rates. USP37 has been identified as the bona fide deubiquitinase of SND1, playing a critical role in stabilizing SND1, thereby augmenting its oncogenic potential. The interaction between USP37 and SND1 was confirmed through extensive proteomics, ubiquitinomics, and interactomics, underscoring their synergistic effects on CRC proliferation and metastasis. Additionally, CDK1 has emerged as a pivotal regulator of USP37, phosphorylating it at threonine 631 rather than serine 628, enhancing its deubiquitinase activity, and consequently stabilizing SND1 to drive CRC malignancy further. Histological analyses of human CRC samples linked the upregulation of CDK1 and USP37 with increased SND1 levels and poor patient prognosis. High-throughput virtual screening and subsequent experimental validation identified Dacarbazine as a pharmacological inhibitor of USP37, and its inhibition disrupted SND1 stability, hindering CRC cell proliferation and metastasis. This study reveals a novel and promising molecular mechanism driving CRC progression through the CDK1-USP37-SND1 axis, highlighting the clinical importance of targeting this pathway to improve patient outcomes.

Aim To evaluate the effectiveness and safety of remimazolam tosylate for administering general anesthesia in morbidly obese patients.Methods This clinical trial was conducted at a single center from De-cember 2021 to October 2023.It assessed 108 morbid-ly obese patients(body mass index,BMI≥40)who underwent laparoscopic sleeve gastrectomy.Patients were randomly assigned to either the remimazaolam group(Group R)or the propofol group(Group P)for general anesthesia induction and maintenance.The primary outcome was to compare the incidence of ad-verse events and postoperative recovery characteristics between the two groups.Results During induction pe-riod,the incidence of adverse events was higher in group P,including hypotension(P＜0.01),hypox-emia(P＜0.05),bradycardia(P＜0.01),and in-creased vasopressor requirement(P＜0.05).The time to loss of consciousness and BIS falling to 60 was shor-ter in group P than in group R(P＜0.01).There were no statistically significant differences between the two groups in terms of postoperative quality of recovery(QoR-40 score),24-hour postoperative pain visual an-alogue scale(VAS)scores and morphine consump-tion.In conclusion,remimazolam tosylate,utilized for anesthesia induction in morbidly obese patients,signif-icantly reduced hypotension and hypoxemia compared to propofol,while it could also maintain similar postop-erative recovery quality.Conclusions Remimazolam is effective in reducing the incidence of hypotension and hypoxaemia during the induction period of general anaesthesia in morbidly obese patients and it is compa-rable to propofol in terms of quality of postoperative re-covery.

Objective:To investigate whether prophylactic use of metal clips is necessary after cold snare polypectomy (CSP) of colorectal polyps of 6-10 mm.Methods:A total of 200 patients with 6-10 mm polyps that met the criteria of cold snare resection in Chengdu Third People's Hospital from 15 February 2022 to 30 May 2022 were randomly divided into two groups: a group that received preventive metal clip treatment and an observation group. Age, gender, body mass index (BMI), Boston score, endoscopy entry time, wound size, operation time, intraoperative bleeding time, postoperative delayed bleeding rate and cost between the two groups were compared and analyzed.Results:Ninety-eight patients in the metal clip group had 122 polyps removed, and 97 patients in the observation group had 119 polyps removed. There was no significant difference in the age, gender, BMI, Boston score, endoscopy entry time or wound size between the two groups. There were significant differences in the operation time (171.03±90.78 s VS 69.81±43.26 s, t=2.266， P=0.010), intraoperative bleeding time (19.98±17.37 s VS 29.16±17.56 s, t=-2.875， P=0.006) and surgery cost (571.63±110.92 yuan VS 366.32±13.2 yuan, t=18.102， P<0.001) between the metal clip group and the observation group. There was no significant difference in the delayed bleeding incidence［0.0%（0/98）VS 1.0%（1/97）， P=0.497］between the two groups. Conclusion:For patients with continuous bleeding time <60 seconds after CSP of 6-10 mm colonic polyps, the prophylactic use of metal clips may reduce the bleeding time, but may increase the operation time and cost. Metal clips have little effect on preventing postoperative complications.

ObjectiveTo analyze the criminal behavior characteristics of alcohol-related crime offenders and explore the relationship between criminal behavior characteristics and criminal responsibility capacity. MethodsBasic information， alcohol use information， psychiatric symptoms before and after the crime， criminological behavioral characteristics and conclusion of judicial evaluation were collected. ResultsThe drinking history of the chronic alcoholism group 25.0 （13.3~30.0） years was significantly longer than that of the acute alcoholism group 1.2 （0~14.3） years. In the chronic alcoholism group， 85.0% drank alcohol at least once a day， 52.5% had morning or bedtime drinking habits， and 92.5% drank mainly alone. Violent crimes accounted for 57.6%. Delirium existed in 52.5% of the chronic alcoholics' mental state at the time of the crime， and 84.6% of the acute alcoholics' mental state was hazy. In the chronic alcoholism group， 42.5% committed the crime with pathological motive， and in the acute alcoholism group， 69.2% committed the crime with realistic motive. Acute alcoholism group 96.2% were assessed as complete criminal responsibility capacity， and chronic alcoholism group 50.0% were assessed as complete criminal responsibility capacity. ConclusionCompared with acute alcoholism offenders， chronic alcoholics had a longer drinking duration， more frequency drinking， and obvious morning drinking or bedtime drinking habits. The nature of alcoholism crime cases was mostly violent. Compared with the chronic alcoholism group， the acute alcoholism group had highly selective motives for committing crimes and were mostly rated as complete criminally responsibility.

Objective:To investigate the predictors of the efficacy of extracorporeal shock wave lithotripsy (ESWL) in the treatment of ureteral calculi, and to evaluate the predictive value of the maximum ureteral wall thickness (UWT) in the treatment of ureteral calculi with ESWL.Methods:The clinical data of 138 patients with ureteral calculi treated with ESWL in the Second People's Hospital of Hefei from January 2020 to December 2020 were retrospectively analyzed. There were 91 males and 47 females. The age was (50.9±14.8) years old. The body mass index was (25.3±3.6) kg/m 2. The stones of 73 cases were located on the left side and 65 cases were on the right side. 70 cases had upper ureteral stones, 18 cases had middle ureteral stones, and 50 cases had lower ureteral stones. The median length of the stone was 8.5 (7.5, 10.5) mm. The CT value of the stone was 509 (343, 783) HU. The anteroposterior diameter of the renal pelvis was 12.0 (10.1, 16.0) mm, and UWT was (2.8 ± 0.8) mm. All patients underwent urinary non-contrast CT before lithotripsy, and the UWT of the stone bed was measured on the CT images. According to the stone removal situation 2 weeks after the operation, the patients were divided into a successful lithotripsy group and a failed lithotripsy group. Univariate analysis was used to compare the differences of various indicators between the two groups, and multivariate logistic regression was used to analyze the independent predictors of ESWL in the treatment of ureteral calculi for the indicators. The receiver operating characteristic (ROC) curve was used to calculate the area under the curve (AUC) of each independent predictor, and the cut-off value, sensitivity and specificity were analyzed. Results:All operations were successfully completed, and the success rate of the first-stage lithotripsy was 71.7% (99/138). The results of univariate analysis showed that the stone length diameter, stone CT value, anteroposterior diameter of renal pelvis, stone skin distance, and UWT were significantly different between the successful lithotripsy group and the failure group ( P<0.05). There was no significant difference in age, gender, body mass index, stone side and stone location ( P>0.05). The results of multivariate logistic analysis showed that stone length ( OR=1.393, P=0.015), stone CT value ( OR=1.002, P=0.043) and UWT ( OR=17.997, P<0.001) were all for the efficacy of ESWL in the treatment of ureteral stones. The ROC curve was used to compare the three independent predictors. The area under the UWT curve was the largest (AUC=0.898, P<0.001), followed by the length of the stone (AUC=0.744, P<0.001), and the CT value of the stone (AUC=0.672, P= 0.002). The cut-off value for UWT was 3.19 mm, which had a sensitivity of 91.9% and a specificity of 71.8% for predicting the success of ESWL lithotripsy. When dividing the patients into thin wall group (UWT ≤3.19 mm) and thick wall group (UWT>3.19 mm) according to the cut-off value, the success rates of one-stage lithotripsy in the two groups were 89.2% (91 / 102) and 22.2% (8/36), respectively ( P<0.05). Conclusions:UWT, calculus length and calculus CT value are independent predictors of the efficacy of ESWL in the treatment of ureteral calculi, and UWT has the best predictive value. When UWT≤3.19 mm, the success rate of ESWL in the treatment of ureteral calculi is higher.

OBJECTIVES: To study the clinical features of intestinal polyps and the risk factors for secondary intussusception in children. METHODS: A retrospective analysis was performed for the medical data of 2 669 children with intestinal polyps. According to the presence or absence of secondary intussusception, they were divided into two groups: intussusception (n=346) and non-intussusception (n=2 323). Related medical data were compared between the two groups. The multivariate logistic regression analysis was used to identify the risk factors for secondary intussusception. RESULTS: Among the children with intestinal polyps, 62.42% were preschool children, and the male/female ratio was 2.08∶1; 92.66% had hematochezia as disease onset, and 94.34% had left colonic polyps and rectal polyps. There were 346 cases of secondary intussusception, with an incidence rate of 12.96% (346/2 669). Large polyps (OR=1.644, P<0.001), multiple polyps (≥2) (OR=6.034, P<0.001), and lobulated polyps (OR=93.801, P<0.001) were the risk factors for secondary intussusception. CONCLUSIONS Intestinal polyps in children often occur in preschool age, mostly in boys, and most of the children have hematochezia as disease onset, with the predilection sites of the left colon and the rectum. Larger polyps, multiple polyps, and lobulated polyps may increase the risk of secondary intussusception, and endoscopic intervention is needed as early as possible to improve prognosis.

Abstract: Objective　To explore the carrying status of four common deafness genes and mutations on 10 loci in newborns in Hainan, and to analyze the molecular epidemiological characteristics of deafness genes and their loci, so as to provide scientific basis for formulating neonatal deafness gene screening strategy and promoting children's hearing health in Hainan. Methods　Newborns born in Hainan from January 2020 to December 2021 were selected as the research objects. The demographic characteristics of the research objects were collected. At the same time, the plantar blood of newborns was collected, and multiplex PCR amplification and directed hybridization combined with high-throughput sequencing technology were applied to detect 10 mutation loci on 4 common deafness genes. T-test or chi square test was used to process the data. Results　A total of 7 124 newborns were included in the study through informed consent, 219 cases of deafness gene mutation were detected with the detection rate of deafness gene of 3.07%. The detection rates of GJB2, SLC26A4, MT-RNR1 and GJB3 were 1.56% (111/7 124), 1.18% (84/7 124), 0.21% (15/7 124) and 0.11% (8/7 124) respectively. Among the 10 loci of the four genes, the positive detection rate of c.235delC locus of GJB2 was the highest, which was 1.38% (98/7 124), followed by c.919-2A>G of SLC26A4 (0.87%, 62/7 124); 2.63% (113/4 289) of the newborns who passed the preliminary hearing screening still carried the deafness gene; in terms of gene type, the detection rate of GJB2 gene in newborns who failed the hearing screening was higher than that in newborns who passed the hearing screening [2.23% (63/7 124) vs 1.12% (48/7 124)，P<0.01]; in terms of gene loci, the detection rate of c.235delC locus in newborns who failed hearing screening was higher than that in newborns who passed hearing screening [2.09% (59/7 124) vs 0.91% (39/7 124)，P<0.01]. Conclusion　The most common deafness genes types in Hainan were GJB2 and SLC26A4; The most common gene mutation sites were c.235delC and c.919-2A>G; 2.63% of the newborns who passed the preliminary hearing screening still carried the deafness gene, among which the high-risk newborns with MT-RNR1 and GJB3 genes were found. Therefore, hearing screening should be combined with deafness gene screening to improve the detection rate of children at high risk of hearing loss.

An innovative sandwich-structural Fe-based metal-organic framework magnetic material(Fe3O4@SW-MIL-101-NH2)was fabricated using a facile solvothermal method.The characteristic properties of the material were investigated by field emission scanning electron microscopy,transmission electron mi-croscopy(TEM),energy-dispersive X-ray spectroscopy,Fourier transform infrared spectroscopy,X-ray powder diffraction,vibrating sample magnetometry,and Brunauer-Emmett-Teller measurements.Fe3O4@SW-MIL-101-NH2 is associated with advantages,such as robust magnetic properties,high specific surface area,and satisfactory storage stability,as well as good selective recognition ability for chlorogenic acid(CA)and its metabolites via chelation,hydrogen bonding,and π-interaction.The results of the static adsorption experiment indicated that Fe3O4@SW-MIL-101-NH2 possessed a high adsorption capacity toward CA and its isomers,cryptochlorogenic acid(CCA)and neochlorogenic acid(NCA),and the adsorption behaviors were fitted using the Langmuir adsorption isotherm model.Then,a strategy using magnetic solid-phase extraction(MSPE)and ultra-performance liquid chromatography coupled with quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF MS/MS)was developed and suc-cessfully employed for the selective pre-concentration and rapid identification of CA metabolites in rat plasma,urine,and feces samples.This work presents a prospective strategy for the synthesis of magnetic adsorbents and the high-efficiency pretreatment of CA metabolites.
