Objective:To evaluate the safety and feasibility of double-port laparoscopic cholecystectomy (LC) combined with transcystic common bile duct (CBD) exploration using ultrafine choledochoscopy on patients with gallbladder stones and common bile duct stones.Methods:Clinical data of 35 patients undergoing double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy in Anhui No.2 Provincial People’s Hospital from December 2021 to June 2024 were retrospectively analyzed, including 8 males and 27 females, aged (45.8±18.1) years. In all patients, the diameter of the gallbladder duct was greater than 3 mm, the maximum diameter of the stones was less than 10 mm, and the number of stones was less than 5, and the gallbladder ducts were normal. Magnetic resonance cholangiopancreatography (MRCP) was used to measure the diameter of CBD, the number and the maximum diameter of stones. The operative time, intraoperative blood loss, postoperative anal exhaust time, postoperative hospital stay and complications (including abdominal infection, biliary tract infection, bile leakage, bleeding, etc.) of all patients were analyzed. The incidence of bile duct stenosis, residual stone or stone recurrence were followed up by telephone or outpatient review.Results:MRCP measurement indicated that the common bile duct diameter of patients was (8.1±1.3) mm. Single CBD stone occurred in 27 cases (77.1%, 27/35), and the mean maximum diameter of CBD stones was (3.9±1.3) mm. All patients successfully underwent the procedure. The operative time was (80.1±10.9) min, the intraoperative blood loss was (25.5±10.2) ml, the recovery time of postoperative anal exhaust was (17.3±4.7) h, and the postoperative hospital stay was (2.5±0.6) d. There were no complications such as abdominal and biliary tract infection, bile leakage and bleeding. All patients were followed up for 1-30 months, with a median follow-up time of 12 months. No biliary stricture, residual stones or recurrence occured during the follow-ups.Conclusion:In selected cases, double-port LC combined with transcystic CBD exploration using ultrafine choledochoscopy could be safe and feasible, with less trauma, quick recovery and short operative time.

To explore the interaction between ASFV capsid protein M1249L and host from the host cellular perspective,M1249L was selected for constructing the bait plasmid(pGBKT7-M1249L)to screen the bone marrow-derived macrophages(BMDMs)cDNA library.After again co-transform and sequence alignment,20 candidate interacting host proteins were screened,such as IL-1β,CTSB and DNAJA3.And then,co-immunoprecipitation assay was performed to verify the interaction be-tween M1249L and host proteins.GO ontology(GO)and KEGG pathway enrichment analyses re-vealed that biological regulation,cellular communication and response to stimulus and others were enriched in biological processes.And these host proteins could share some pathways,including toll-like receptor signaling pathway and Nod-like receptor signaling pathway.Therefore,the results provides the theoretical basis for further research on the mechanism of ASFV M1249L in viral in-fection and immune regulation.

Objective To study the effects of Shugan Jieyu capsules on the cardiac function and state of mind of chronic heart failure(CHF)patients with anxiety and depression.Methods Ninety-four CHF patients with anxiety and depression were randomly divided into the Shugan Jieyu capsule treatment group and mental therapy control group.Self-rating depression Scale(SDS),self-rating anxiety scale(SAS),left ventricular ejection fraction(LVEF),N-terminal pro-B-type natriuretic peptide(NT-proBNP),the 6-minute walking test(6MWT),hemoglobin(Hb),interleukin-6(IL-6),albumin(ALB)and high-sensitivity c-reactive protein(hs-CRP)were compared between the two groups before and after treatment using t-tests and chi-square tests in order to find out about the efficacy of Shugan Jieyu capsules in CHF patients with anxiety and depression.Results After 8 weeks of treatment,SDS,SAS,NT-proBNP,hs-CRP and IL-6 were all significantly lower,especially in the treatment group,while LVEF,6MWT,Hb and ALB were significantly higher or longer,particularly in the treatment group.Conclusion Shugan Jieyu capsules can effectively alleviate anxiety and depression in CHF patients,improve the cardiac function and nutritional status,and mitigate inflammation.

Objective To explore macrophage subpopulations in ischemic stroke (IS) by using single-cell RNA sequencing (scRNA-seq) data analysis and High-Dimensional Weighted Gene Co-Expression Network Analysis (hdWGCNA). Methods Based on single-cell sequencing data, transcriptomic information for different cell types was obtained, and macrophages were selected for subpopulation identification. hdWGCNA, cell-cell communication, and pseudotime trajectory analysis were used to explore the characteristics of macrophage subpopulations following IS. Key genes related to IS were identified using microarray data and validated for diagnostic potential through Receiver Operating Characteristic (ROC) analysis. Gene Set Enrichment Analysis (GSEA) was conducted to investigate the potential functions of these genes. Results The scRNA-seq data analysis revealed significant changes in macrophage subpopulation composition after IS. A specific macrophage subpopulation enriched in the stroke group was identified and designated as MCAO-specific macrophages (MSM). Pseudotime trajectory analysis indicated that MSM cells were in an intermediate stage of macrophage differentiation. Cell-cell communication analysis uncovered complex interactions between MSM cells and other cells, with the CCL6-CCR1 signaling axis potentially playing a crucial role in neuroinflammation. Two gene modules associated with MSM were identified via hdWGCNA, significantly enriched in pathways related to NOD-like receptors and antigen processing. By integrating differentially expressed MSM genes with conventional transcriptomic data, three IS-related hub genes were identified: Arg1, CLEC4D, and CLEC4E. Conclusion This study reveals the characteristics and functions of macrophage subpopulations following IS and identifies three hub genes with potential diagnostic value, providing novel insights into the pathological mechanisms of IS.

Due to the fact that the articular cartilage of children's joints has not yet been fully ossified, visualizing the adjacent anatomical structures during the clinical diagnosis and treatment of joint diseases and injuries in children is a challenging issue. Arthrography is an efficient, convenient, and minimally invasive technique, and is particularly crucial for the visualization of children's hip joints. Currently, arthrography technology is widely employed during surgeries for developmental dysplasia of the hip (DDH), and in recent years, numerous studies have concentrated on the efficacy of joint angiography, exploring its assessment and predictive roles during and after the operation. We review the overview of hip joint arthrography techniques, such as the concept of arthrography, the selection of access routes for hip joint arthrography, the process of hip joint arthrography, the dosage and operation of contrast agents, and the adverse reactions of contrast agents; the use of hip joint arthrography to evaluate the quality of closed reduction; the use of hip joint arthrography to predict the future development and outcome of the acetabulum after closed reduction; the use of hip joint arthrography in the study of open reduction or osteotomy; the use of hip joint arthrography to observe the morphology of soft tissues in the hip joint; the use of hip joint arthrography in combination with nuclear magnetic resonance to observe the anatomical structure of the acetabular labrum. Summarizing the research results of arthrography for evaluating the corresponding indicators of the hip joint helps improve the matching between the femoral head and the acetabulum and the accuracy of evaluating the quality of reduction, uncovers identifying factors such as labrum varus that hinder concentric reduction, enhances the ability to predict the development and outcome of the acetabulum, and has significant guiding significance for the precise selection of the timing of surgical intervention for early and residual deformities in children with DDH. Exploring the application of arthrography technology in evaluating the quality of closed reduction in DDH and predicting the development of the acetabulum after reduction is expected to provide meaningful references for orthopedic surgeons in the current clinical diagnosis, treatment, and research of DDH.

Objective:To explore the influence of multidisciplinary treatment (MDT) on clinical staging and diagnosis and treatment strategies for rectal cancer.Methods:A retrospective case series study was conducted. The clinical data of 142 rectal cancer patients who underwent surgical treatment in Shanxi Provincial People's Hospital from March 2021 to December 2021 were retrospectively analyzed. According to whether to implement MDT or not, all patients were divided into MDT group (68 cases) and non-MDT group (74 cases). Relevant clinical data including patients' basic information (gender, age, etc.), TNM staging, whether to receive neoadjuvant radiotherapy and chemotherapy or not, surgical methods, R0 resection rate of both groups were compared. The implementation methods and the effects of MDT for patients were summarized.Results:There were statistically significant differences in the proportion of clinical N staging at initial diagnosis, whether to receive neoadjuvant radiotherapy and chemotherapy or not of both groups (all P < 0.05). The overall agreement rate of clinical T staging at initial diagnosis and pathological T staging was 67.6% (46/68), 50.0% (37/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 4.54, P = 0.033). The overall agreement rate of N staging at initial diagnosis and pathological N staging was 50.0% (34/68), 54.1% (40/74), respectively in the MDT group and the non-MDT group, and the difference was not statistically significant ( χ2 = 0.23, P = 0.629). The treatment rate of neoadjuvant radiotherapy and chemotherapy was 57.4% (39/68) and 4.1% (3/74), respectively in the MDT group and the non-MDT group, and the difference was statistically significant ( χ2 = 48.33, P < 0.001). The R0 resection rate in both the MDT group and non-MDT group was 100.0%, and no tumor tissue was found at the upper, lower, and circumferential margins. Conclusions:MDT could provide more accurate clinical staging and more effective diagnosis and treatment opinions for patients, and provide reliable guidance for the treatment selections.

Objective To conduct a detailed clinical phenotypic analysis and gene mutation detection on an au-tosomal dominant Van der Hoeve syndrome family,and to identify the pathogenic gene mutation sites of the family and the impact of the mutation on gene coding.Methods Clinical data including medical history,physical examina-tion and auxiliary examination were collected and peripheral blood samples were collected from the Van der Hoeve syndrome families.Exome sequencing and Sanger sequencing were performed on 22 family members.The data were analyzed using bioinformatics software.Results The family had a total of 5 generations,with each generation expe-riencing consecutive illnesses.Each generation of men and women could suffer from the disease,which conformed to the characteristics of autosomal dominant inheritance.The 12 patients in this family were all born with blue sclera and short stature.8 patients had a history of fractures and could heal normally.3 patients were considering hearing loss caused by Van der Hoeve syndrome.12 patients had a base deletion(c.1128delT)in exon 17 of the COL1A1 gene,causing a change in the amino acid coding after position 376 and ending the amino acid coding prematurely at position 539.10 asymptomatic individuals in this family didn't had this mutation.Conclusion The patient of this family was identified as Van der Hoeve syndrome caused by c.1128 delT mutation.

Objective To systematically evaluate the efficacy and safety of dronedarone in preventing early recurrence of atrial fibrillation(AF)after ablation.Methods PubMed,Web of Science,Cochrane Library,Embase,CNKI,WanFang Data and VIP databases were electronically searched to collect the clinical studies on the efficacy and safety of dronedarone in preventing early recurrence of AF after ablation from the inception to April 16,2024.Two researchers independently screened the literature,extracted data,and assessed the risk of bias of the included studies.Meta-analysis was performed by using RevMan 5.3 software.Results A total of three randomized controlled trials and eight cohort studies were ultimately included,including 1 534 patients.The results of meta-analysis showed that there was no statistically significant difference in the early recurrence rate of AF after ablation between the dronedarone group and the amiodarone group(RR=1.15,95％CI 0.90 to 1.47,P=0.25).Compared with the amiodarone group,the dronedarone group had a higher incidence of bleeding(RR=2.28,95％CI 1.08 to 4.81,P＜0.05),a higher incidence of gastrointestinal adverse reactions(RR=3.87,95％CI 1.39 to 10.74,P=0.009)and a lower incidence of thyroid dysfunction(RR=0.15,95％CI 0.06 to 0.40,P＜0.001).There was no statistically significant difference in the incidence of postoperative bradycardia,liver and kidney dysfunction,and total adverse drug reactions between the two groups(P＞0.05).Compared with the propafenone group,the dronedarone group had a lower early recurrence rate of AF after ablation(RR=0.31,95％CI 0.17 to 0.57,P＜0.001).However,there was no statistically significant difference in the incidence of adverse reactions between them(P＞0.05).Conclusion Current evidence suggests that dronedarone is as effective in preventing early recurrence after AF ablation as amiodarone,but more effective than propafenone.In terms of safety,compared to amiodarone,dronedarone has a lower risk of thyroid dysfunction,but a higher risk of gastrointestinal adverse reactions and bleeding.Due to the limited quality and quantity of the included studies,more large sample,multi-center and high-quality studies are needed to verify the above conclusion.
