In recent years， repetitive transcranial magnetic stimulation （rTMS） has garnered significant attention as a therapeutic approach for sleep disorders in the elderly. However， the prevailing rTMS protocols are predominantly developed based on normative neurophysiological data derived from young adults and fail to incorporate individualized parameters tailored to the brain characteristics of the elderly. To address this gap， the consensus development group synthesized the latest evidence from 2010 to 2025 and established a standardized rTMS protocol specifically for elderly patients with sleep disorders. Adhering to the Appraisal of Guidelines for Research and Evaluation II （AGREE II） framework， systematically screened randomized controlled trials （RCTs） and systematic reviews regarding rTMS in the treatment of sleep disorders across various conditions. Meanwhile， the Grading of Recommendations Assessment， Development and Evaluation （GRADE） system was employed to rigorously grade the quality of evidence and the strength of recommendations. This consensus guideline delineates precise rTMS protocols for the management of sleep disorders in the elderly， highlights the adjustment of stimulation intensity according to scalp-cortex distance recommends either MRI‑guided neuronavigation or the Beam F3/F4 heuristic approach for accurate target localization， thereby providing precise rTMS intervention protocol for sleep disorders in the elderly， aiming to enhance clinical efficacy while ensuring treatment safety. ［Funded by National Key Research and Development Program （number， 2023YFC3603200）； General Program of Shenzhen Science and Technology Innovation Commission （number， JCYJ20240813112859008， JCYJ20240813112900002）； Youth Program of Shenzhen Kangning Hospital （number， KN2023A004）； www.guidelines-registry.cn number， PREPARE-2026CN530］

Immobilized enzyme-based enzyme electrode biosensors, characterized by high sensitivity and efficiency, strong specificity, and compact size, demonstrate broad application prospects in life science research, disease diagnosis and monitoring, etc. Immobilization of enzyme is a critical step in determining the performance (stability, sensitivity, and reproducibility) of the biosensors. Random immobilization (physical adsorption, covalent cross-linking, etc.) can easily bring about problems, such as decreased enzyme activity and relatively unstable immobilization. Whereas, directional immobilization utilizing amino acid residue mutation, affinity peptide fusion, or nucleotide-specific binding to restrict the orientation of the enzymes provides new possibilities to solve the problems caused by random immobilization. In this paper, the principles, advantages and disadvantages and the application progress of enzyme electrode biosensors of different directional immobilization strategies for enzyme molecular sensing elements by specific amino acids (lysine, histidine, cysteine, unnatural amino acid) with functional groups introduced based on site-specific mutation, affinity peptides (gold binding peptides, carbon binding peptides, carbohydrate binding domains) fused through genetic engineering, and specific binding between nucleotides and target enzymes (proteins) were reviewed, and the application fields, advantages and limitations of various immobilized enzyme interface characterization techniques were discussed, hoping to provide theoretical and technical guidance for the creation of high-performance enzyme sensing elements and the manufacture of enzyme electrode sensors.

Hepatocellular carcinoma(HCC), the third leading cause of cancer-related death worldwide, is characterized by high mortality and recurrence rates. Common treatments include hepatectomy, liver transplantation, ablation therapy, interventional therapy, radiotherapy, systemic therapy, and traditional Chinese medicine(TCM). While exhibiting specific advantages, these approaches are associated with varying degrees of adverse effects. To alleviate patients' suffering and burdens, it is crucial to explore additional treatments and elucidate the pathogenesis of HCC, laying a foundation for the development of new TCM-based drugs. With emerging research on gut microbiota, it has been revealed that microbiota plays a vital role in the development of HCC by influencing intestinal barrier function, microbial metabolites, and immune regulation. TCM, with its multi-component, multi-target, and multi-pathway characteristics, has been increasingly recognized as a vital therapeutic treatment for HCC, particularly in patients at intermediate or advanced stages, by prolonging survival and improving quality of life. Recent global studies demonstrate that TCM exerts anti-HCC effects by modulating gut microbiota, restoring intestinal barrier function, regulating microbial composition and its metabolites, suppressing inflammation, and enhancing immune responses, thereby inhibiting the malignant phenotype of HCC. This review aims to elucidate the mechanisms by which gut microbiota contributes to the development and progression of HCC and highlight the regulatory effects of TCM, addressing the current gap in systematic understanding of the "TCM-gut microbiota-HCC" axis. The findings provide theoretical support for integrating TCM with western medicine in HCC treatment and promote the transition from basic research to precision clinical therapy through microbiota-targeted drug development and TCM-based interventions.

Allergic rhinitis (AR), a globally prevalent immune-mediated inflammatory condition, is still an incurable disease. In the present study, we have validated the impact of the Kelch-like ECH associated protein 1 (Keap1)-related oxidative stress and inflammatory response in clinical AR patient peripheral blood and nasal swab samples, emphasizing the biological relevance of Keap1 and AR. Targeting Keap1 -nuclear factor erythroid 2-related factor 2 (Nrf2) related anti-oxidative stress may be effective for AR intervention. Drawing inspiration from the Keap1 homodimerization and the E3 ligase characteristics, we herein present a design of novel bivalent molecules for chemical knockdown of Keap1. For the first time, we characterized ternary complexes of Keap1 dimer and one molecule of bivalent compounds. The best bivalent molecule 8 encompasses robust capacity to degrade Keap1 as a homoPROTAC^KEAP1. It efficaciously suppresses inflammatory cytokines in extensively different cells, including human nasal epithelial cells. Moreover, in an AR mouse model, we confirmed that the chemical degradation induced by homoPROTAC^KEAP1 led to therapeutic benefits in managing AR symptoms, oxidative stress and inflammation. In summary, our findings underscore the efficacy of targeting the Keap1 system through the homoPROTAC-ing technology as an innovative and promising treatment strategy for the incurable allergic disorders.

Nutritional support therapy is one of the extremely important treatment methods for patients in the intensive care unit. Timely and effective nutritional support regimens can improve patients' immune function, reduce complications, and optimize clinical outcomes. Energy expenditure is influenced by multiple factors, including patients' baseline characteristics (such as physical condition, gender, age) and dynamic changes in indicators (such as body temperature, nutritional support regimens, and therapeutic interventions). The currently recognized "gold standard" for accurately assessing energy metabolism in clinical practice is the indirect calorimetry system, also known as the metabolic cart. This device monitors carbon dioxide production and oxygen consumption in real time and uses specific algorithms to estimate the metabolic proportions of the three major nutrients (carbohydrates, fats, and proteins) in energy expenditure. An appropriate nutrient ratio helps maintain the balance between supply and demand in the body's nutritional metabolism. In the management of critically ill patients, the application of the metabolic cart enables personalized nutritional therapy, avoiding over- or under-supply of energy and optimizing the use of medical resources. Furthermore, with real-time, quantitative data support from the energy metabolism monitoring system, clinicians can develop more precise nutritional intervention strategies, thereby improving patient prognosis. This article provides a systematic review of the technical features of the metabolic cart and its application value in various critical care scenarios, aiming to offer a reference for indirect calorimetry in clinical practice.

Objective To analyze the correlation between preoperative oxidative stress levels and reperfusion arrhythmia(RA)in post-PCI patients with acute myocardial infarction(AMI).Methods A total of 120 AMI patients undergoing PCI in our hospital from May 2022 to May 2024 were recruited,and according to the occurrence of RA,they were divided into a RA group(46 cases)and a non-RA group(74 cases).The general clinical data were collected in all patients.Multivariate logistic regression was used to screen the influencing factors for the occurrence of RA after PCI in AMI patients.ROC curve analysis was applied to determine the predictive value of the preoperative oxidative stress levels for the occurrence of RA after PCI.Results The RA group had significantly larger proportions of onset-to-PCI time＜6 h,inferior wall infarction,and culprit vessel at thrombolysis in myocardial infarction(TIMI)grade 0 than the non-RA group(P＜0.01).The preoperative level of malondialdehyde(MDA)was obviously higher,while that of superoxide dismutase(SOD)was notably lower in the RA group than the non-RA group(P＜0.01).Multivariate logistic regression analysis showed that culprit vessel at TIMI grade 0(OR=3.484,95％CI:1.043-11.633,P=0.042),onset-to-PCI time＜6 h(OR=4.143,95％CI:1.227-13.989,P=0.022),inferior wall infarction(OR=54.265,95％CJ:2.027-1450.950,P=0.017),and preoperative MDA(OR=2.495,95％CI:1.570-3.966,P=0.001)were risk factors for RA after PCI in AMI patients;preoperative SOD(OR=0.823,95％CI:0.749-0.905,P=0.001)was a protective factor.ROC curve analysis indicated that the AUC value of preoperative MDA and pre-operative SOD in predicting RA after PCI in AMI patients was 0.809 and 0.849,respectively(P＜0.001).Conclusion Culprit vessel at TIMI grade 0,onset-to-PCI time＜6 h,inferior wall infarc-tion,and preoperative MDA and SOD are all influencing factors for RA in post-PCI AMI patients.Moreover,preoperative MDA and SOD levels can effectively predict the risk of RA after PCI in the patients.

To report 3 cases of acute generalized exanthematous pustulosis (AGEP) caused by hydroxychloroquine. All the 3 patients were females, aged 23, 30, and 28 years respectively. In cases 1 and 3, the rashes appeared 4 days and 12 days respectively after the treatment with hydroxychloroquine for systemic lupus erythematosus; case 2, who was 8 weeks pregnant, developed rashes 10 days after starting hydroxychloroquine treatment for antiphospholipid syndrome. All the 3 patients had high fever, and clinically presented with generalized round or oval-shaped edematous erythema on the face, neck, trunk and limbs, covered with a large number of pinhead-sized pustules, and with multiple erythema multiforme-like lesions on the trunk and both upper limbs, including targetoid lesions. Mutations in the IL36RN gene were identified in all the 3 patients: a homozygous mutation c.115+6T>C in the IL36RN gene was found in case 1, and her parents were heterozygous carriers; case 2 inherited the heterozygous mutation c.115+6T>C in the IL36RN gene from her mother; the heterozygous mutation c.115+6T>C found in case 3 was a de novo mutation. A diagnosis of AGEP was made in all the 3 cases. Cases 1 and 2 received subcutaneous injections of adalimumab in addition to the treatment of their underlying diseases, and skin lesions markedly regressed after 1 week of treatment; case 3 was treated with high-dose glucocorticoids, and lesions subsided after 4 weeks; no significant adverse reactions were observed in cases 1 and 2, however, femoral head necrosis was noted in case 3. During a follow-up period of 42 months, none of the patients experienced recurrence, and case 2 gave birth to a healthy baby boy after 8-month treatment.

Objective To investigate the effect of exogenous luteinizing hormone (LH) on vitrification granulosa cells and its mecha-nisms. Methods The granulosa cells of 4-week-old preadolescent mice were selected and divided into the fresh group (without vitrification procedure),the vitrification group (treated according to vitrification procedure) and the LH group (treated with 0.3 IU/L of LH intervention on the basis of the vitrification group). Granulocyte count was performed,and Realtime PCR and Western blot were used to detect the expression changes of Foxl2,PI3K,AKT and mTOR mRNAs and proteins in each group. Results Compared with the vitrification group,the total number of granulosa cells in the LH group was significantly increased (P<0.05),and the expression of Foxl2,PI3K,AKT and mTOR mRNAs and proteins were elevated (P<0.05). Conclusion The intevention of exogenous LH is beneficial for the survival of vitrifi-cation granulosa cells,and the mechanism may be related to the activation of PI3K/AKT/mTOR pathway.

Objective To investigate the potential causal relationship between autoimmune liver diseases(AILD)and type 1 diabetes(T1D)based on two-sample Mendelian randomization(TSM R)method.Methods Genome-wide association study(GWAS)data were obtained from the Open GWAS database.Forward Mendelian randomization analysis was performed with three types of AILD as exposures and T1D as the outcome,while reverse analysis was conducted with T1D as the exposure and three types of AILD as outcomes.Single nucleotide polymorphism(SNP)that was significantly associated with the exposure was selected as instrumental variable(IV).The inverse variance weighting(IVW)method was employed as the primary analytical ap-proach to explore the bidirectional causal relationships between AILD and T1D.Sensitivity analyses,including heterogeneity tests and horizontal pleiotropy tests,were conducted to ensure the robustness of the results.Results The IVW analysis indica-ted that primary biliary cholangitis(PBC)increased the risk of T1D(OR=1.14,95％CI:1.082-1.201,P=9.41 ×10-7),while no significant associations was observed for primary sclerosing cholangitis(PSC)and autoimmune hepatitis(AIH)with T1D(PSC:OR=1.058,95％CI:0.966-1.159,P=0.223;AIH:OR=0.992,95％CI:0.953-1.033,P=0.706).Conversely,T1D was associated with an increased risk of PBC(OR=1.272,95％CI:1.143-1.416,P=1.024×10-5)and PSC(OR=1.246,95％CI:1.072-1.448,P=0.004),but not AIH(OR=1.032,95％CI:0.931-1.144,P=0.551).Conclusion This study demon-strates a bidirectional causal relationship between PBC and T1D,and T1D also increases the risk of PSC.These findings provide new insights and directions for future research into the molecular mechanisms underlying these associations.

Objective To explore the roles of the mechanoreceptor Yes-associated protein 1(YAP1)and piezo type mechanosensitive ion channel component 2(PIEZO2)in mechanotransduction in mouse bladder urothelial cells.Methods Mouse bladder urothelial cells were subjected to mechanical stretching using the FX-6000T cell stretching system and treated with the YAP1-specific inhibitor verteporfin(VP).The expressions of PIEZO2,YAP1 and connective tissue growth factor(CTGF)at the mRNA and protein levels,as well as changes in cellular adenosine triphosphatase(ATP)concentration,were detected using reverse transcription quantitative PCR(RT-qPCR)and Western blotting(WB).Results After stretching stimulation,under the fluorescence microscope,it was observed that the diameter length of the stretched cells were longer than that before stretching,and the difference was statistically significant(P＜0.05).The expressions of YAP1,PIEZO2 and CTGF at the mRNA and protein levels were increased in the stretched group compared to those of the non-stretched group(P＜0.05).VP effectively reduced the expressions of YAP1,PIEZO2 and CTGF at the mRNA and protein levels after stretching stimulation(P＜0.05).Stretching stimulation significantly increased the intracellular ATP concentration,while VP was able to inhibit the increase in ATP concentration,with a statistically significant difference(P＜0.000 1).Conclusion Stretching stimulation increased the expressions of YAP1 and PIEZO2 in bladder urothelial cells and promoted the release of ATP;verteporfin inhibited the increase in YAP1 activity and the overexpression of PIEZO2 caused by stretching,thereby reducing the release of ATP.It is suggested that mouse bladder urothelial cells may primarily sense mechanical signals through the YAP1-PIEZO2-ATP pathway.
