BACKGROUND:The repair process of myocardial injury involves complex cellular and molecular mechanisms,especially mitochondrial calcium homeostasis,macrophage autophagy and pyroptosis pathways.Traditional Chinese medicine(TCM)has shown significant clinical efficacy in improving myocardial injury,but its mechanism of action needs to be thoroughly investigated. OBJECTIVE:To investigate the role of mitochondrial calcium homeostasis-mediated macrophage autophagy and pyroptosis pathways in myocardial injury,and to summarize the progress of TCM in this field. METHODS:A computerized search was performed for relevant literature from the database inception to March 2024 in the Web of Science,PubMed and CNKI.The search terms were"mitochondrial calcium homeostasis,macrophage autophagy,macrophage pyroptosis,traditional Chinese medicine,myocardial injury,myocardial injury reperfusion"in Chinese and English.Through literature review,we analyzed the relationship between mitochondrial calcium homeostasis and macrophage autophagy and pyroptosis,explored the mechanism of their roles in myocardial injury,and summarized the pathways of multi-targeted,multi-pathway effects of TCM. RESULTS AND CONCLUSION:The maintenance of mitochondrial calcium homeostasis has been found to be closely related to the normal function of cardiomyocytes.Macrophages can participate in the repair process of myocardial injury through autophagy and pyroptosis pathways.Autophagy contributes to cell clearance and regulation of inflammatory response,while pyroptosis affects myocardial repair by releasing inflammatory factors.TCM regulates mitochondrial calcium homeostasis and macrophage function through multiple mechanisms.For example,astragalosid regulates calcium homeostasis by lowering mitochondrial membrane potential and inhibiting cytochrome C,and epimedium glycoside plays a role in reducing β-amyloid deposition.In addition,herbal compounds and single drugs promote myocardial repair by activating or inhibiting specific signaling pathways,such as PI3K/AKT and nuclear factor-κB signaling pathways.Future studies should focus on the interactions between mitochondrial calcium homeostasis,autophagy and pyroptosis pathways,as well as how TCM can exert therapeutic effects through these pathways to provide new strategies and drugs for the treatment of myocardial injury.

Knee osteoarthritis (KOA) is a common chronic degenerative disease that not only causes pain and reduces the quality of life for patients but also imposes a significant societal burden. Clinical pathways can be developed by referencing recommendations from clinical practice guidelines to localize guidelines within the context of integrated traditional Chinese and western medical systems. However, existing clinical pathways suffer from shortcomings such as deficiencies in integrated traditional Chinese and western medical diagnosis and treatment, inadequate shared decision-making between healthcare providers and patients, and suboptimal visualization of clinical pathways. This study aimed to address and optimize the clinical pathway of KOA by comprehensively organizing and localizing the recommended guidelines. The concept of integrated traditional Chinese and western medicine was reflected through the construction of a path of joint decision-making between doctors and patients, emphasizing the coexistence of diagnosis and screening, the combination of clinical and imaging staging, joint decision-making between doctors and patients, and treatment stages. This pathway emphasizes patient-centered approach, with pain relief and functional rehabilitation running parallel, achieving the implementation of evidence-based concepts in practical medical practice. It provides a concrete basis for joint decision-making between doctors and patients in the integrated treatment of KOA with traditional Chinese and western medicine, which helps to improve diagnosis and treatment efficiency and patient quality of life.

INTRODUCTION: Lecanemab has shown promise in treating early Alzheimer's disease (AD), but its safety and efficacy in Chinese populations remain unexplored. This study aimed to evaluate the safety and 6-month clinical outcomes of lecanemab in Chinese patients with mild cognitive impairment (MCI) or mild AD. METHODS: In this single-arm, real-world study, participants with MCI due to AD or mild AD received biweekly intravenous lecanemab (10 mg/kg). The study was conducted at Hainan Branch, Ruijin Hospital Shanghai Jiao Tong University School of Medicine. Patient enrollment and baseline assessments commenced in November 2023. Safety assessments included monitoring for amyloid-related imaging abnormalities (ARIA) and other adverse events. Clinical and biomarker changes from baseline to 6 months were evaluated using cognitive scales (mini-mental state examination [MMSE], montreal cognitive assessment [MoCA], clinical dementia rating-sum of boxes [CDR-SB]), plasma biomarker analysis, and advanced neuroimaging. RESULTS: A total of 64 patients were enrolled in this ongoing real-world study. Safety analysis revealed predominantly mild adverse events, with infusion-related reactions (20.3%, 13/64) being the most common. Of these, 69.2% (9/13) occurred during the initial infusion and 84.6% (11/13) did not recur. ARIA-H (microhemorrhages/superficial siderosis) and ARIA-E (edema/effusion) were observed in 9.4% (6/64) and 3.1% (2/64) of participants, respectively, with only two symptomatic cases (one ARIA-E presenting with headache and one ARIA-H with visual disturbances). After 6 months of treatment, cognitive scores remained stable compared to baseline (MMSE: 22.33 ± 5.58 vs . 21.27 ± 4.30, P = 0.733; MoCA: 16.38 ± 6.67 vs . 15.90 ± 4.78, P = 0.785; CDR-SB: 2.30 ± 1.65 vs . 3.16 ± 1.72, P = 0.357), while significantly increasing plasma amyloid-β 42 (Aβ42) (+21.42%) and Aβ40 (+23.53%) levels compared to baseline. CONCLUSIONS: Lecanemab demonstrated a favorable safety profile in Chinese patients with early AD. Cognitive stability and biomarker changes over 6 months suggest potential efficacy, though high dropout rates and absence of a control group warrant cautious interpretation. These findings provide preliminary real-world evidence for lecanemab's use in China, supporting further investigation in larger controlled studies. REGISTRATION ClinicalTrials.gov , NCT07034222.

Objective To explore the effect of the knockdown of transmembrane 9 superfamily protein member 2 (TM9SF2) on the replication of vesicular stomatitis virus (VSV), and investigate its role in the mechanism of antiviral innate immunity. Methods Small interfering RNA (siRNA) was used to knock down the TM9SF2 gene in human non-small cell lung cancer A549 cells. The CCK-8 method was used to assess cell proliferation. A VSV-green fluorescent protein (VSV-GFP) infected cell model was established. The plaque assay was used to measure the viral titer in the supernatant. RT-qPCR and Western blotting were employed to quantify the mRNA and protein levels of VSV genome replication in A549 cells following VSV infection, as well as the expression of interferon β (IFN-β) mRNA and interferon regulatory factor 3 (IRF3) protein phosphorylation following polyinosinic-polycytidylic acid (poly(I:C)) stimulation. Results Compared to the negative control, the knockdown of TM9SF2 exhibited a significant effect, with no observed impact on A549 cell proliferation. The VSV-GFP infected A549 cell model was successfully established. After viral stimulation, fluorescence intensity was reduced following TM9SF2 knockdown, and the mRNA and protein levels of VSV were significantly downregulated. The viral titer of VSV was decreased. After poly(I:C) stimulation, TM9SF2 knockdown significantly upregulated the mRNA level of IFN-β and the phosphorylation level of IRF3 protein. Conclusion The knockdown of TM9SF2 inhibits the replication of vesicular stomatitis virus, and positively regulates the type I interferon signaling pathway, thus enhancing the host's antiviral innate immune response.

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 investigate the prevalence and potential classification of symptoms after total knee arthroplasty (TKA) in patients with knee osteoarthritis (KOA), and to analyze the differences in demographic characteristics and surgical data, compare the different potential subgroups, in order to provide a basis for clinical symptom management plans.Methods:This study was a multicenter cross-sectional survey. Through convenience sampling, patients with KOA undergoing TKA in the orthopaedic wards of four tertiary hospitals in Urumqi were selected as the study from November 2023 to February 2024. The study subjects were surveyed using a general information questionnaire, the Visual Analogue Scale (VAS) for pain, the Hospital Anxiety and Depression Scale (HADS), and the Pitts Burgh Sleep Quality Index (PSQI), and the degree of postoperative joint swelling and size of ecchymosis were measured. Latent class analysis was performed using Mplus 8.3 software, and Logistic regression analysis was conducted using SPSS 26.0 software to explore the influencing factors of the latent classes.Results:Totally 337 effective questionnaires were collected, and the recovery rate was 94.7% (337/356), and the age distribution ranged from 47 to 85 (65.19 ± 6.99) years old, with 90 (26.7%) males and 247 (73.3%) females. There were 92.3% (311/337) of TKA patients with postoperative symptom cluster. The symptom cluster of patients with TKA were identified as 3 classes. They were named as "high level pain-psychological disorder group"(12.5%, 39/311), "high bruises-moderate psychological disorders group"(25.4%, 79/311) and "low symptom burden group" (62.1%, 193/311). The results of the unordered multi-class logistic regression analysis showed that age 45-59 years ( OR = 2.367), body mass index 24.0-27.9 kg/m 2 ( OR = 0.207), living with children/parents ( OR = 6.473), and this being the second joint surgery ( OR = 0.040) were the factors influencing the "high level pain-psychological disorders group" (all P<0.05). The factors influencing the "high bruises-moderate psychological disorders group" were living with children/parents ( OR = 4.023), comorbid chronic diseases ( OR = 1.979, 3.842), and intraoperative blood loss ≤100 ml ( OR = 2.342) (all P<0.05). Conclusions:The postoperative symptom cluster of TKA patients have a relatively high incidence, and there is heterogeneity within the symptom cluster, so nurses need to identify at-risk patients early according to the characteristics of different categories and give interventions.

Objective To investigate the relationship between cognitive impairment and sleep parameters in acute ischemic stroke patients with obstructive sleep apnea(OSA).Methods A total of 343 patients with acute ischemic stroke and OSA were selected.The cognitive function was assessed using the simple mental state examination scale(MMSE).Patients were divided into the stroke with OSA and cognitive impairment group(MMSE＜27 points,n=119)and the stroke with OSA without cognitive impairment group(MMSE≥27 points,n=224).General data,TOAST etiological classification and distribution of cerebral infarction lesions were collected.The intelligent sleep monitoring system was used to calculate apnea hypopnea index(AHI)and evaluate OSA.Objective sleep monitoring parameters were collected at night.Sleep monitoring was conducted within 24 h of admission and continuous monitoring for≥3 nights.Continuous monitoring duration≥7 h every night to obtain night sleep structure parameters.Multifactor Logistics regression was used to analyze the relationship between cognitive impairment and sleep parameters in stroke patients with OSA.Results Compared with the stroke with OSA without cognitive impairment group,the proportion of age,diabetes history and HHcy history,the proportion of patients with infarct lesions located in frontal,temporal,parietal,occipital,thalamus,basal ganglia,brainstem and hemioval center increased in the stroke with OSA and cognitive impairment group,and the number of years of education decreased,the number of waking times,the proportion of light sleep and AHI increased,the nighttime sleep efficiency and deep sleep period decreased(P＜0.05).Logistics regression analysis showed that after controlling for years of education,age and other interference factors,nighttime sleep efficiency and AHI were strongly associated with cognitive impairment in acute ischemic stroke patients with OSA(P＜0.05).The increased nighttime sleep efficiency was protective factor for cognitive impairment,and increased AHI was risk factor for cognitive impairment.Conclusion Cognitive impairment in acute ischemic stroke patients with OSA is closely related to sleep parameters,in which the increased sleep efficiency at night is a protective factor for cognitive impairment,and the increased AHI is a risk factor.

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.
