Objective:To evaluate the efficacy of transumbilical single-port robotic-assisted laparoscopic surgery for congenital choledochal cysts in children.Methods:Clinical data of 13 children with congenital choledochal cysts undergoing surgery at the Provincial Hospital of Fuzhou University from January 2024 to June 2024 were retrospectively analyzed, including 4 males and 9 females, aged 48 (24, 60) months. All children underwent transumbilical single-port robotic-assisted laparoscopic radical resection of congenital choledochal cyst with common hepatic duct jejunum Roun-en-Y anastomosis by the same surgeon. The efficacy of this technique was evaluated by surgical safety indicators such as operation time and intra-operative blood loss, as well as indicators of the postoperative scar assessment scale (OSAS).Results:All surgeries were successfully performed without conversion to open surgery. The operation time was (200±22) min. The blood loss was (8.07±2.56) ml without intraoperative blood transfusion. The time to start water feeding was (2.76±0.83) d and the time to start liquid diet was (3.92±1.12) d. The postoperative hospital stay was (7.00±3.37) d and the postoperative follow-up time was (5.38±2.06) months. No postoperative complications such as bile reflux gastritis and cholangitis were seen in patients. No dilatation of the common hepatic duct or intrahepatic bile ducts were observed at three months postoperatively. There were good indicators of satisfaction with the appearance of wounds as assessed by OSAS.Conclusion:Transumbilical single-port robotic-assisted laparoscopic surgery could be safe and effective for congenital choledochal cysts in children.

Objective:To study the correlation between miR-122 and early HBV infection and analyze its application value in early infection of voluntary blood donors.Methods:A total of 150 samples from voluntary blood donors in Fujian Blood Center from May 2021 to July 2022 were collected and divided into group N(normal group),group E(ELISA single positive group),and group D(both ELISA and nucleic acid positive group),and the general information of the three groups of blood donors was collected.Total RNA was extracted from the three groups of samples,and the expression level of miR-122 was detected by qRT-PCR.The expression differences of miR-122 among the three groups of samples were statistically analyzed,and the correlation between the expression level of miR-122 in group D and its HBV DNA copy number was analyzed.The miRNA database was used to predict the potential target genes of miRNA and perform bioinformatics analysis.Results:There was no statistical difference in gender,education level,and occupation distribution among the three groups,but the age distribution and number of blood donations among different groups were statistically significant.Compared with group N,the relative expression levels of miR-122 in the plasma of group E and group D were significantly downregulated(P＜0.05);the relative expression level of miR-122 in group D was more significantly downregulated than that in group E(P＜0.001).Pearson correlation analysis showed that the expression level of miR-122 in group D was negatively correlated with the HBV-DNA copy number(R2=-0.804,P＜0.01).Two potential target genes were screened using the miRNA database:ALDOA(aldolase A)and PKM(pyruvate kinase).GO analysis results showed that the potential target genes of miRNA mainly involved in biological processes including cell homeostasis and regulation of transcriptional processes.Conclusion:Downregulation of miR-122 expression is closely related to early HBV infection and replication activity.

With the rapid development of competitive sports, the incidence of anterior cruciate ligament (ACL) injury is on the rise. Such injuries may shorten athletes′ career and lead to other long-term adverse consequences. Although athletes generally recover well after ACL reconstruction, many still struggle to return to their pre-injury performance levels. Advances in the understanding of ACL anatomy and injury mechanisms, along with the evolution of surgical techniques and rehabilitation methods, have provided more individualized and tailored options for athletes following ACL injuries. However, there is currently no consensus in China regarding surgical and rehabilitation strategies for competitive athletes aiming to return to sports after ACL injuries. To this end, the Sports Medicine Committee of the Chinese Research Hospital Association and the Editorial Board of the Chinese Journal of Trauma jointly formulated the Expert consensus on surgical treatment and rehabilitation for competitive sports athletes returning to sports after anterior cruciate ligament injury ( version 2025), and presented 14 recommendations covering surgical indications, preoperative rehabilitation, surgical timing, surgical strategies and postoperative rehabilitation strategies, aiming to improve the surgical treatment and rehabilitation system for ACL injuries in competitive athletes and facilitate their return to high-level sports performance after injury.

Objective:To investigate the clinical characteristics and genetic etiology of a child with Cortical dysplasia, complex, with other brain malformations 4 (CDCBM4) and epilepsy due to a TUBG1 gene variant. Methods:A child diagnosed with CDCBM4 and epilepsy at the Children′s Medical Center of the Affiliated Hospital of Guangdong Medical University in May 2024 was selected as the study subject. Clinical data were retrospectively analyzed. Peripheral venous blood samples were collected from the child and her parents for genomic DNA extraction. Trio-based whole-exome sequencing (WES) was performed, and candidate variants were validated by Sanger sequencing. According to the Standards and Guidelines for the Interpretation of Sequence Variants established by the American College of Medical Genetics and Genomics (ACMG), candidate variants were classified for pathogenicity. This study was approved by the Medical Ethics Committee of the Affiliated Hospital of Guangdong Medical University (Ethics No.: PJ2021-097).Results:The child, a 4-month-old female infant, had no special facial features, normal limb muscle strength, and increased muscle tone of infantile onset, with generalized tonic-clonic seizures as the main manifestation. During seizures, she exhibited head retroflexion, tightly closed eyes, and tonic convulsions of the limbs, occurring approximately 2-3 times per day. Electroencephalogram suggested bilateral anterior predominant medium-to-high amplitude 7-8 Hz mixed rhythm discharges. Head MRI revealed ventricular system dilatation and pachygyria. Trio-WES results indicated that the child has harbored a TUBG1 gene variant of c. 776C>T (p.Ser259Leu). Sanger sequencing verification showed that neither of her parents had carried the same variant, confirming it as de novo in origin. According to the ACMG guidelines, the variant was rated as pathogenic (PS2+ PS3+ PM2_Supporting+ PP3). Combining the child′s clinical phenotype, the child was diagnosed as CDCBM4 with epilepsy. Conclusion:Children with CDCBM4 and epilepsy due to TUBG1 gene variants may show pachygyria or agyria and commonly present with intellectual and motor developmental delays and seizure disorders of variable severity. The heterozygous TUBG1 c. 776C>T (p.Ser259Leu) variant is likely the genetic etiology underlying this disorder. The results of this study has expanded the mutational spectrum of the TUBG1 gene associated with CDCBM4 and epilepsy.

Objective To investigate the current status of cardiovascular nurses in intake and output recording of heart failure patients,and to provide a basis for further standardizing these practices.Methods A convenience sampling method was used to survey 7,761 cardiovascular nurses from 31 provinces in China in May 2024 using a self-designed questionnaire.The survey content included the content and methods of recording fluid intake and output,methods of liquid measurement,health education for patients and caregivers,and verification of the accuracy of fluid intake and output records.The chi-square test was used for comparison between groups.Results A total of 7,726 valid questionnaires were collected,with an effective response rate of 99.55％.Solid food(85.00％)and insensible water loss such as sweat(59.63％)were the lowest proportion items in the recording of intake and output,respectively.A total of 6,343 nurses(82.10％)reported that their wards had standardized"intake and output record forms".A total of 3,782 nurses(48.95％)were able to use graduated measuring cups to quantify water intake,and 3,587 nurses(46.43％)could use a"food water content table"to convert the water content of solid foods.Additionally,5,050 nurses(65.36％)involved patients and caregivers in the recording of intake and output,and 5,419 nurses(70.14％)provided health education on intake and output recording to patients and caregivers.Furthermore,4,753 nurses(61.52％)verified the accuracy of the 24-hour intake and output records after completion.Nurses whose wards regularly provided training on intake and output recording,as well as those whose wards included the accuracy of intake and output recording in quality control,demonstrated better practice outcomes in this regard(P＜0.001).Conclusion The current clinical nursing practice of cardiovascular nurses in recording the intake and output of heart failure patients needs improvement.Relevant academic organizations should further refine the standards related to intake and output recording.Medical institutions should focus on strengthening training and quality control,optimizing clinical operation procedures,and providing material,institutional,and human resource support to improve the accuracy of fluid intake and output recording for heart failure patients and ensure patient safety.

Background: and Purpose Ruptured intracranial aneurysms (RIA) are associated with a mortality rate of up to 40% in the Chinese population, highlighting the critical need for targeted treatment interventions for at-risk individuals. Although the impact of aldehyde dehydrogenase 2 (ALDH2) gene mutations on susceptibility to intracranial aneurysms (IA) is well documented, the potential connection between ALDH2 rs671 single-nucleotide polymorphism (SNP) and RIA remains unexplored. Given the increased prevalence of ALDH2 gene mutations among Chinese Han individuals, it is clinically relevant to investigate the link between ALDH2 rs671 SNP and IA rupture. Methods: A prospective study was conducted on 546 patients diagnosed with IA to investigate the association between ALDH2 rs671 SNP and the risk of IA rupture. Results: The ALDH2 rs671 SNP (ALDH2*2) was significantly more prevalent in patients with unruptured IA (UIA) than in those with RIA (32.56% vs. 18.58%, P=0.004). Multivariate logistic regression analysis revealed that people with the ALDH2 mutation (ALDH2*1/*2 and ALDH2*2/*2 gene type) had a significantly reduced odds ratio (OR=0.49; 95% confidence level [CI] 0.27–0.88; P=0.018) for RIAs. Age-specific subgroup analysis indicated that the ALDH2 mutation provided a stronger protective effect in individuals aged 60 years and above with IA compared to those under 60 years old (OR=0.38 vs. OR=0.52, both P<0.05). Conclusion The incidence of RIA was significantly higher in individuals with a normal ALDH2 gene (ALDH2*1/*1) than in those with an ALDH2 rs671 SNP (ALDH2*1/*2 or ALDH2*2/*2). ALDH2 rs671 SNP may serve as a protective factor against RIA in the Chinese Han population.
