ObjectiveTo investigate the role of DEAD-box helicase 3 X-linked （DDX3X） in immune-mediated liver injury （ILI）， and to clarify its mechanism by regulating endoplasmic reticulum stress （ERS）-dependent apoptotic pathway and its association with the clinical progression of hepatitis B. MethodsMice were given injection of concanavalin A （ConA） via the caudal vein to establish a model of ILI， PBS （control group） and different concentrations of ConA were injected into the tail vein of hepatocyte-specific DDX3X-knockout mice （DDX3X^ΔHep and DDX3X-flox mice （DDX3X^fl/fl）， respectively.. The log-rank survival analysis， measurement of the serum levels of aspartate aminotransferase （AST） and alanine aminotransferase （ALT）， and HE staining of liver tissue were performed to assess liver injury， and qRT-PCR and Western Blot were used to measure the mRNA and protein expression levels of glucose-regulated protein 78 （GRP78）， CCAAT/enhancer-binding protein homologous protein （CHOP）， and DDX3X in liver tissue. Intraperitoneal injection of 4-phenylbutyric acid （4-PBA， 100 mg/kg） was performed to inhibit ERS. Serum samples （n=30） and liver tissue samples （n=6） were collected from healthy controls， chronic hepatitis B （CHB） patients， and hepatitis B virus-associated liver failure （HBV-LF） patients； ELISA was used to measure the serum level of DDX3X， and qRT-PCR/Western Blot was used to analyze the expression of targets in liver tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the control group of mice， the expression of DDX3X in the liver of mice induced by ConA was significantly increased after liver injury （P<0.05）， and hepatocyte-specific DDX3X knockout increased the 72-hour survival rate of mice by 55% （compared with 20% in the DDX3X^fl/fl group）， with significant reductions in the serum levels of ALT and AST （P<0.000 1） and the expression levels of the ERS markers GRP78 and CHOP （P<0.05）. After ERS was inhibited by 4-PBA， there was alleviation of liver injury （with reductions in ALT and AST， P <0.001） and a reduction in DDX3X expression （P<0.01）. The analysis of clinical samples showed that the mRNA and protein expression levels of liver DDX3X in CHB patients and HBV-LF patients were significantly higher than those in healthy controls （all P<0.01）， and there was a significant increase in the serum level of DDX3X in HBV-LF patients （P<0.000 1）. ConclusionDDX3X exacerbates ILI by regulating the ERS-dependent apoptotic pathway （GRP78/CHOP）， and its expression is associated with the progression of hepatitis B. Therefore， it can be used as a potential therapeutic target.

Objective To investigate risk factors for residual lesions after initial transurethral resection of bladder tumors(TURBT)and risk factors for tumor recurrence after second TURBT in patients with non-muscle-invasive bladder cancer(NMIBC)in order to provide reference for clinical management.Methods A case-control study design was adopted to include 120 NMIBC patients who underwent initial TURBT and then second surgery within 2～8 weeks in our department from January 2017 to January 2025.Based on the presence of residual lesions after the initial TURBT or not,the patients were divided into a residual lesion group(n=34)and a non-residual lesion group(n=86).Chi-square test and multivariate logistic regression analysis were performed to identify potential risk factors for residual lesions following the initial TURBT.Univariate and multivariate Cox regression models were used to analyze potential risk factors for tumor recurrence after the second TURBT.Results The residual lesion rate after initial TURBT was 28.33％.Chi-square test analysis revealed that tumor stage T1(Chi-square=5.756,P=0.016)and broad tumor base(Chi-square=4.331,P=0.037)were factors influencing residual lesions after initial TURBT.Multivariate logistic regression analysis identified tumor stage T1(OR=3.047,95％CI:1.128～8.226,P=0.028)as an independent risk factor for residual lesions after initial TURBT.The tumor recurrence rate after second TURBT was 17.5％.Multivariate Cox regression analysis identified tumor stage T1(OR=4.258,95％CI:1.248～14.532,P=0.021),intravesical chemotherapy instillation after second TURBT(OR=3.539,95％CI:1.284～9.752,P=0.015),history of urinary system tumors(OR=3.002,95％CI:1.145～7.873,P=0.025)and high platelet-to-lymphocyte(PLR)ratio(OR=2.798,95％CI:1.115～7.023,P=0.028)as independent risk factors for tumor recurrence after second TURBT.Conclusion Tumor stage T1 and broad tumor base are risk factors for residual lesions after initial TURBT,while tumor stage T1,intravesical chemotherapy instillation after second TURBT,history of urinary system tumors and high PLR ratio are risk factors for tumor recurrence after second TURBT.Comprehensive analysis on above 4 indicators can effectively assess the risk of tumor recurrence in NMIBC patients following second TURBT,and timely early medical intervention is beneficial for improving patient outcomes.

Objective:To evaluate the effect of combining contralateral high-frequency transcranial magnetic stimulation (rTMS) with biofeedback-controlled empty swallowing training on dysphagia among stroke survivors.Methods:Eighty dysphagic stroke survivors were divided at random into a control group, a biofeedback group, an rTMS group and a combined treatment group, each of 20. In addition to routine dysphagia rehabilitation, the biofeedback group and the rTMS group received empty swallowing training based on biofeedback or high-frequency rTMS applied to the healthy motor cortex as appropriate. The combined treatment group was given both. The treatment was administered once daily, 5 days a week for 3 consecutive weeks. Before and after the treatment, all of the subjects′ swallowing was evaluated using the penetration aspiration scale (PAS), functional oral intake scale (FOIS) and a standardized swallowing assessment (SSA). The latency and amplitude of the mylohyoid muscle′s motor evoked potentials (MEPs) were also recorded before and after the treatment.Results:After the treatment, significant improvement was observed in the average PAS, FOIS and SSA scores as well as in the latency and amplitude of the MEPs in the four groups. The average results in the combined treatment group were significantly better than in the other 3 groups. The latency of the mylohyoid muscle′s MEP was significantly shorter in the combined group than in the control and biofeedback groups on average, while the amplitude was significantly greater than in the control group.Conclusion:Combining contralateral high frequency rTMS with empty swallowing training based on biofeedback can better improve the swallowing of dysphagic stroke survivors.

Objective To investigate the clinical effects of sinus elevation surgery and implant restorationdue to in-sufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis(OMS)and to provide a refer-ence for use in clinical practice.Methods This study was reviewed and approved by the Ethics Committee,and in-formed consent was obtained from the patients.Forty-five teeth were extracted from patients with OMS in the maxillary posterior area(the study group).Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group.Forty-eight teeth were extracted from patients without"OMS"in the maxillary posterior area(the control group),and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group.In the study group,13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation,and the other 32 cases were addressed with crest-approach sinus elevation.In the control group,8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation.Restora-tions were placed 6 to 8 months after surgery.The patients were followed up 21 days,3 months,and 8 months after im-plantation and every 6 months after the placement of the restorations.The sinus bone gain(SBG),apical bone height(ABL)and marginal bone loss(MBL)were statistically analyzed 24 months after the restoration.Results The average preoperative mucosal thickness in the 45 patients in the study group was(1.556±0.693)mm,which was significantly larger than that in the control group(1.229±0.425)mm(P＜0.001).There were no perforations in either group.Twenty-four months after restoration,there was no significant difference in the SBG,ABH or MBL between the two groups(P＞0.05).Conclusion After the extraction of teeth from patients with OMS,the inflammation of the maxillary sinus de-creased,and the bone height and density in the edentulous area were restored to a certain degree.The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective: To investigate the clinical effects of sinus elevation surgery and implant restorationdue to insufficient bone massafter tooth extraction in patients with odontogenic maxillary sinusitis (OMS) and to provide a reference for use in clinical practice. Methods: This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Forty-five teeth were extracted from patients with OMS in the maxillary posterior area (the study group). Sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction in the study group. Forty-eight teeth were extracted from patients without "OMS" in the maxillary posterior area (the control group), and sinus elevation and implantation were performed due to insufficient bone height in the implant area 6-8 months after tooth extraction inthe control group. In the study group, 13 cases of discontinuous maxillary sinus floor bone and residual alveolar bone height of the maxillary sinus floor less than 4 mm were addressed with lateral wall sinus elevation, and the other 32 cases were addressed with crest-approach sinus elevation. In the control group, 8 cases of residual alveolar bone height less than 4 mm in the maxillary sinus floor were addressed with lateral wall sinus,and the other 40 cases were addressed with crest approach sinus elevation. Restorations were placed 6 to 8 months after surgery. The patients were followed up 21 days, 3 months, and 8 months after implantation and every 6 months after the placement of the restorations. The sinus bone gain (SBG), apical bone height (ABL) and marginal bone loss (MBL) were statistically analyzed 24 months after the restoration. Results: The average preoperative mucosal thickness in the 45 patients in the study group was (1.556 ± 0.693) mm, which was significantly larger than that in the control group (1.229 ± 0.425) mm (P<0.001). There were no perforations in either group. Twenty-four months after restoration, there was no significant difference in the SBG, ABH or MBL between the two groups (P>0.05). Conclusion After the extraction of teeth from patients with OMS, the inflammation of the maxillary sinus decreased, and the bone height and density in the edentulous area were restored to a certain degree. The effects of sinus floor lifting surgery and implant restoration do not differ between patients with and without OMS.

Objective To systematically evaluate the experiences of drug self-management in elderly patients with multiple chronic illnesses,so as to provide references for the development of personalized drug self-management intervention programs.Methods Qualitative research on drug self-management experiences of elderly patients with multiple chronic diseases was retrieved from PubMed,Cochrane Library,Embase,CINAHL,Web of Science,Scopus,CNKI,Wanfang,VIP and SinoMed.The retrieval time limit is from the establishment of the databases to November 2023.The qualitative research quality evaluation criteria of the Joanna Briggs Institute Evidence-based Health Care Center in Australia was used to evaluate quality of studies.The results were integrated by meta-integration method.Results A total of 9 studies were included,and 33 research results were extracted,and 4 integrated results and 12 categories were synthesized.The integration results included the objective dilemmas and challenges of drug self-management,the low level of drug literacy,willingness to engage in positive behavior attempts,need of multi-party assistance.Conclusion The objective dilemmas of drug self-management and low level of drug literacy in elderly patients with multimorbidity will seriously affect their health outcomes.Medical staffs should pay attention to the different experiences of patients in the process of drug self-management,identify the needs of patients,formulate targeted intervention support strategies,and improve the level of drug self-management in elderly patients.

Objective: To investigate the effect of G protein-coupled receptor 108(GPR108) gene knockout on systemic inflammation in lipopolysaccharide(LPS)-induced sepsis mice. Methods: Male C57BL/6 mice and GPR108 gene knockout mice were randomly divided into 4 groups: WT group, WT-LPS group, KO group, KO-LPS group. The physiological characteristics of mice in different groups were observed, and the morphological changes of liver and lung tissues were observed. Macrophages were extracted from bone marrow and subjected to flow cytometry to detect their M1 polarization status. The expression levels of IL-6 in liver and lung tissues, macrophages, and serum were also measured. Results: KO-LPS group mice showed significant liver and lung tissue damage, with a significantly greater number of bone marrow-derived macrophages polarizing towards M1 in the KO-LPS group compared to the WT-LPS group. Additionally, at the tissue, cellular, and serum levels, the expression of IL-6 in the KO-LPS group mice was significantly higher than that in the WT-LPS group mice(P<0.05). Conclusion During the systemic inflammatory infection induced by LPS in mice, the lack of GPR108 exacerbates the systemic inflammatory response. GPR108 has an inhibitory effect on the inflammatory response in mice with LPS-induced sepsis.
