Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective:To summarize the clinical characteristics and surgical outcomes of endolymphatic sac tumor（ELST）, and improve the experience of diagnosis and treatment of this disease. Methods:A retrospective analysis was conducted on the clinical data of patients with ELST who underwent surgical treatment by the Department of Otolaryngology Head and Neck Surgery, Beijing Friendship Hospital, Capital Medical University from January 2015 to December 2024.The clinical and image features, perioperative management, surgical methods and follow-up results of the disease were summarized. Results:Of the 6 cases, 4 were male and 2 were female. The primary clinical characteristics were hearing loss（6 cases）, tinnitus（5 cases）, dizziness（2 cases）, facial paralysis（1 case）, and headache（1 case）. CT and MRI of temporal bone were performed in all cases. The manifestation of CT was a space occupying lesion centered on the region of endolymphatic sac, accompanied by bone destruction and intertumoral calcification. MRI showed tumor center isosignal and peripheral hypersignal in T1 and T2 sequences in 3 cases, and mixed hypersignal in T1 and T2 sequences in 3 cases. Enhancement was observed in all cases on the enhanced scan. 5 cases underwent DSA examination and showed the tumors were supplied by the occipital artery（2 cases）, posterior auricular artery（4 cases）, and the bunch of internal carotid artery（1 case）. Embolization of the feeding artery was performed in 3 patients. Five patients underwent tumor resection. Translabyrinthine approach were performed in 4 cases, and middle cranial fossa approach was performed in 1 case. All cases followed up for 24 to 70 months with no distant metastases or death. Two patients experienced twice recurrences and were treated with surgical operation. The tumors were found to be closely related to the internal auditory canal or dura during the surgery. Conclusion:The clinical manifestations of ELST are not typical, and hearing loss is the most common clinical symptom. CT and MRI exhibit typical imaging characteristics. ELST has a risk of recurrence, and the tumor should be carefully managed when invade to the internal auditory canal and dura to reduce postoperative recurrence.

Objective To investigate the potential core target and its mechanism of Simiao San(SMS)in the treatment of rheumatoid arthritis(RA)using network pharmacology and animal experiments.Methods Active components and corresponding SMS targets were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP)and cross-referenced with the Universal Protein(UniProt)database.RA-related targets were screened from The Human Gene Database(GeneCards),Online Mendelian Inheritance in Man(OMIM),Therapeutic Target Database(TTD),DrugBank,and Disease Gene Network(DisGeNet).Protein-protein interaction(PPI)networks were constructed for shared targets between SMS and RA using Search Tool for the Retrieval of Interacting Genes/Proteins(STRING),followed by Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analyses via The Database for Annotation,Visualization and Integrated Discovery(DAVID).A"herb active component-disease target-signaling pathway"network was established to predict the mechanism of SMS in RA treatment.Molecular docking was performed between aryl hydrocarbon receptor(AHR)and the core active components of SMS to identify AHR-targeting constituents.For animal experiments,30 female SPF-grade C57/BL mice were randomly divided into normal,model,methotrexate(1.52 mg/kg,every 3 days),and SMS(12.48 g/kg,daily)groups with a 30-day intervention.Ankle diameter and arthritis index scores were measured.HE staining was used to assess joint inflammation,whereas immunohistochemistry(IHC)was used to measure cytochrome P450 1A1(CYP1A1),nuclear factor kappa B subunit p65(p65),and phosphorylated p65(p-p65)protein expression levels.Multiplex immunofluorescence(mIHC)was used to evaluate forkhead box protein P3(FOXP3)and interleukin-17A(IL-17A)protein expression.Results Forty-one active components and 228 targets of SMS were identified from TCMSP,whereas 1,207 RA-related targets were extracted from GeneCards,OMIM,TTD,DrugBank,and DisGeNet.Ninety-four overlapping targets were analyzed,yielding 612 GO terms and 143 KEGG pathways.Molecular docking of the ligand-binding domain of AHR with the top 10 Degree values of compounds of SMS(quercetin,stigmasterol,wogonin,beta-sitosterol,kaempferol,baicalein,et al.)revealed that stigmasterol,beta-sitosterol,(S)-canadine,and isocorypalmine was able to bind to AHR stably.In vivo,compared to the model group,the mice of the SMS and methotrexate groups joint swelling and arthritis index scores reduced(P<0.01).IHC indicated elevated CYP1A1 protein and decreased p65 and p-p65 protein levels in the SMS and methotrexate groups(P<0.05,P<0.01).mIHC demonstrated reduced IL-17A and increased FOXP3 protein expression in the SMS and methotrexate groups(P<0.05,P<0.01).Conclusion SMS alleviates joint inflammation in RA mice,potentially by targeting AHR,one of the core targets.SMS may suppress excessive inflammatory responses by activating AHR and inhibiting p65 phosphorylation.Additionally,SMS modulates the helper T cells 17/regulatory T cells balance by downregulating IL-17A and upregulating FOXP3.These results suggest that AHR is a key mediator in T-cell immune regulation.

Objective:To evaluate the efficacy of modified splenic arteriovenous shunt surgery at the distal pancreatic tail in combined pancreas-kidney transplantation.Methods:A retrospective analysis was conducted on 24 recipients who underwent combined pancreas-kidney transplantation with the modified splenic arteriovenous shunt at the pancreatic tail from November 2023 to October 2024 (shunt group) and 231 recipients who received conventional splenic artery and vein ligation since 2016 (ligation group). The incidence of perioperative thrombosis and severe adverse events was compared between the two groups using the chi-square test or Fisher's exact test. Independent sample t-tests were performed to assess postoperative pancreatic and renal function recovery as well as blood perfusion in 15 recipients from the shunt group and 20 from the ligation group who underwent CT perfusion imaging (CTP).Results:The incidence of perioperative splenic arteriovenous thrombosis was lower in the shunt group (0) compared to the ligation group (4.76%, 11/231), though the difference was not statistically significant ( P=0.606). One month postoperatively, the shunt group demonstrated significantly lower serum amylase levels than the ligation group (99.61±19.62 vs. 148.20±70.67 U/L, P=0.018). However, at the time of CTP examination, serum lipase (67.87±32.35 vs. 45.11±17.94 U/L, P=0.014) and creatinine levels (131.79±26.41 vs. 112.1±24.98 μmol/L, P=0.034) were significantly higher in the shunt group. Urea nitrogen levels were also significantly higher in the shunt group both one month postoperatively (11.24±4.64 vs. 8.51±3.01 mmol/L, P=0.043) and at the CTP examination (10.41±1.78 vs. 6.87±1.91 mmol/L, P=0.001). Regarding pancreatic perfusion, blood volume in both the pancreatic head (15.99 ± 3.51 vs. 20.67 ± 5.47 ml/100 g, P = 0.024) and tail (17.19±4.24 vs. 27.40±19.80 ml/100 g, P=0.039) was significantly lower in the shunt group. After one minute of splenic artery perfusion, the shunt group exhibited significantly higher splenic artery blood flow (755.85±101.50 vs. 574.00 ± 142.06 ml·min -1· (100 g) -1, P<0.001) and blood volume (58.90 ±19.93 vs. 23.21±17.02 ml/100 g, P=0.007) compared to the ligation group. These differences persisted after two minutes of perfusion (blood flow: 793.83±68.57 vs. 503.78 ± 130.80 ml·min -1· (100 g) -1, P<0.001; blood volume: 64.22±15.74 vs. 34.32±20.39 ml/100 g, P=0.002). For the transplanted kidney, the shunt group had significantly lower blood flow (113.10±28.55 vs. 232.76±113.37 ml·min -1· (100 g) -1, P<0.001), blood volume (28.95±10.79 vs. 38.36±12.38 ml/100 g, P=0.047), and capillary surface permeability (PS) (26.49±16.57 vs. 43.02±20.37, P = 0.042) in the upper pole. Similar reductions in blood flow, blood volume, and PS were observed in the middle dorsal region ( P=0.018, 0.021, and 0.048, respectively) and lower pole ( P<0.001, P=0.048, and P=0.012, respectively). Conclusion:The modified splenic arteriovenous shunt at the pancreatic tail appears to be a safe and effective approach to reducing the risk of pancreatic graft thrombosis. This technique facilitates effective diversion of pancreatic parenchymal blood flow into the splenic vein, alleviating hyperperfusion of the transplanted pancreas. While renal blood perfusion was reduced postoperatively, it did not adversely affect renal function.

Rheumatoid arthritis （RA） is a systemic autoimmune disease with local joint pain as the main clinical manifestation. It is one of the diseases specifically responding to traditional Chinese medicine （TCM）. The occurrence of RA is not only related to innate factors like genetic disorder but also associated with environmental factors， such as diets and microbial infection. The intestine， a vital human organ with digestive and immune functions， is a place where microorganisms colonize and exert intestinal metabolism-improving， barrier-protecting， and immunomodulatory effects. As the research on the onset and treatment of RA is deepening， the potential relationship of intestinal structural and functional abnormalities with the pathogenesis and progression of RA has been revealed. As clinical and experimental studies indicated， joint inflammation coexists with the impaired barrier function， imbalanced immune cells， and disordered gut microbiota. The theory of the gut-joint axis in the pathogenesis， progression， and treatment of RA is highly consistent with the holistic view in TCM. The recent pharmacological studies have shown that Chinese medicine prescriptions and active components can inhibit inflammation， protect joints， and maintain the intestinal function. This article summarizes the basic connotation of the gut-joint axis in RA and the mechanism by which TCM protect the intestinal barrier and modulate the immunity by regulating the gut microbiota structure and improving microbial metabolism in the treatment of RA. This review gives insights into the future research on the gut-joint axis in RA.

Objective:To explore the effects of Undaria pinnatifida polysaccharides(UPPs)on depressive-like behavior,neurotransmitter content,oxidative stress,and the hypothalamus-pituitary-adrenal(HPA)axis in rats treated with chronic unpredictable mild stress(CUMS).Methods:A rat model of depression was prepared using the CUMS method,and rats were treated with normal saline(NS)or different doses of UPPs by gavage.The general condition of the rats was observed,and depressive-like behavior was detected by the open field test(OFT),sucrose preference test(SPT),and forced swimming test(FST).The activity or levels of 5-hydroxytryptamine(5-HT),dopamine(DA)and norepinephrine(NE),malondialdehyde(MDA),superoxide disidase(SOD)and catalase(CAT),adrenocorticotrop-ic hormore(ACTH),corticosterone(CORT)in the hippocampus or serum of rats were detected using commercial kits.Western Blot was used to detect the expression level of hippocampal glucocorticoid receptor(GR)protein,and hema-toxylin-eosin(HE)staining was used to observe the tissue structure of hippocampus of rats.Results:The depressive-like behavior of rats in the UPPs medium and high dose groups was significantly improved(P＜0.05).In the UPPs high dose group,the contents of 5-HT,DA,and NE in the hippocampus of rats increased(P＜0.05),while the con-tents of MDA in both serum and hippocampus decreased(P＜0.05),and the activities of SOD and CAT increased(P＜0.05).The contents of ACTH and CORT in serum decreased(P＜0.05).In the UPPs medium dose group,the levels of hippocampal MDA and CAT,as well as serum SOD,ACTH,and CORT were improved(P＜0.05).The expression level of GR protein in the hippocampus increased(P＜0.05),and the pathological changes in the hipp-ocampal dentate gyrus were significantly improved.Conclusion:UPPs can alleviate depressive-like behavior in CUMS rats,and its mechanism may be related to increasing the content of monoamine neurotransmitters in the hippocampus,reducing oxidative stress damage,and HPA axis hyperfunction.

Objective:The included angle of the outermost edge of the pedicle and the front edge of the central line of T12, L1, and L12 in the axial projection was compared before surgery (the incidence angle of the pedicle was set as α). A horizontal line passing through point C was made to cross the inner edge of the pedicle in the axial projection and the intersection point was designated as point D. The distance between point C and point D was compared among T12, L1, and L2. The advantages and feasibility of the measurement of these parameters for guiding puncture and bone cement injection in L1 percutaneous vertebroplasty were investigated.Methods:The clinical data of 91 patients with L1 osteoporotic vertebral compression fracture who underwent percutaneous vertebroplasty in The First People's Hospital of Chu Zhou from January 2018 to November 2021 were retrospectively analyzed. Axial α and CD of the L1 vertebral body and its adjacent vertebral bodies were measured. The amount of bone cement injected during the surgery, bone cement leakage rate, and pre- and post-surgery Visual Analogue Scale score were determined.Results:The α and CD of L1 in the axial projection were (20.43 ± 1.61)° and (5.37 ± 1.08) mm, respectively. Bone cement leakage rates of unilateral and bilateral approaches of L1 vertebral body were 35% and 12%, respectively, and there was a significant difference between the two approaches ( χ2 = 6.08, P < 0.05). There was no significant difference in the amount of bone cement injected during the surgery between unilateral and bilateral approaches of L1 ( P > 0.05). There was no significant difference in pre- and post-surgery Visual Analogue Scale scores between unilateral and bilateral approaches of L1 ( P > 0.05). Conclusion:The α and CD of L1 in the axial projection are smaller than those of other adjacent vertebral bodies, which is of great significance for selecting a puncture path and reducing bone cement leakage.

Objective:To study the correlations of micro RNA (miR)-432 expression with cell proliferation and migration, and tripartite motif containing protein 38 ( TRIM38) gene expression in isocitrate dehydrogenase ( IDH) wild-type glioma, and overall survival (OS) of these patients. Methods:(1) The miRNA expression microarray data of 198 glioma patients (81 with IDH mutant, 106 with IDH wild type and 11 with unknown type) and 5 nontumorous brain tissues (controls) were downloaded from China Glioma Genome Atlas (CGGA); expression differences of miR-432 between IDH mutant and IDH wild type glioma subgroups and normal controls were compared. According to the median value of miR-432 expression in IDH wild-type glioma samples, these patients were divided into miR-432 high expression group ( n=51) and miR-432 low expression group ( n=53), Kaplan-Meier survival analysis was used to compare the OS, univariate and multivariate Cox regression analyses were used to determine the factors influencing OS, and Pearson correlation was used to analyze the relation between miR-432 expression and TRIM38 gene expression. (2) Human glioma cell line U251 was routinely cultured and divided into nonsense sequence control group and miR-432 mimics group; CCK-8 assay was used to detect the cell viability on the 1 st-5 th d of cultivation; Transwell assay was used to detect the cell migration; quantitative reverse transcription PCR (RT-qPCR) was used to detect the TRIM38 mRNA expression. (3) According to the binding sites between miR-432 and TRIM38 gene predicted by miRNA target gene prediction database, the wild-type TRIM38 3'-terminal untranslated region (3'-UTR) and mutant TRIM38 3'-UTR sequences were designed; U251 cells were divided into miR-432 nonsense sequence+wild-type TRIM38 3'-UTR group, miR-432 mimics+wild-type TRIM38 3'-UTR group, miR-432 nonsense sequence+mutant TRIM38 3'-UTR group, and miR-432 mimics+mutant TRIM38 3'-UTR group; the luciferase activity in these 4 groups was detected by microplate assay. Results:(1) The miR-432 expression in IDH wild-type glioma was significantly decreased as compared with that in the IDH mutant one ( P<0.05). The OS of patients in the miR-432 low-expression group was significantly shorter as compared with that in the miR-432 high-expression group ( P<0.05). Age, glioma grading, and miR-432 expression were significantly correlated with OS of IDH wild-type glioma patients ( P<0.05), but miR-432 expression level was not an independent influencing factor for OS ( P>0.05). The miR-432 and TRIM38 mRNA expressions in IDH wild-type glioma samples were negatively correlated ( r=-0.255, P=0.018). (2) As compared with nonsense sequence control group, miR-432 mimics group had significantly lower cell activity on the 2 rd-5 th d of cultivation, significantly smaller number of migrated cells, and statistically decreased TRIM38 mRNA expression ( P<0.05). (3) The luciferase activity of cells in the miR-432 mimics+wild-type TRIM38 3'-UTR group was significantly lower than that in the miR-432 nonsense+wild-type TRIM38 3'-UTR group ( P<0.05). Conclusion:The miR-432 expression is low in IDH wild-type glioma tissues, and it is associated with poor prognosis of these patients; miR-432 overexpression can inhibit the proliferation and migration of glioma cells, which may be related to its specific binding of TRIM38 gene and interference the expression of this gene.
