Helicobacter pylori （H. pylori） infection is not only associated with gastrointestinal diseases， but also potentially links with neuropsychiatric disorders revealed by recent studies. Through a systematic review of the existing literature， this review summarizes epidemiological evidence for the association between H. pylori infection and diseases such as Parkinson′s disease （PD）， Alzheimer′s disease （AD）， multiple sclerosis （MS）， migraine， depression， and anxiety disorders， and further explores potential mechanisms by which it affects central nervous system function， including neural pathways mediated by the enteric nervous system and the vagus nerve， immune pathways mediated by inflammatory cytokines， and endocrine pathways mediated by gut microbial metabolites. Additionally， the current challenges facing H. pylori eradication therapy and the prospects for emerging adjuvant strategies such as probiotics and fecal microbiota transplantation are discussed. Finally， future research directions are outlined， emphasizing the need for prospective cohort studies based on standardized diagnostic methods and further investigation using animal models to elucidate the pathophysiological mechanisms， with the aim of providing new perspectives for the prevention， treatment， and early intervention of related neuropsychiatric disorders.

Preoperative localization of pulmonary small nodules can effectively improve the safety and success rate of video-assisted thoracoscopic surgery(VATS),but there are still controversies regarding the selection of relevant techniques.Interventional Oncology Committee of the Chinese Anti-Cancer Association organized domestic interventional radiology experts engaged in treatment of pulmonary malignancies,based on clinical experience and evidence-based medical evidence to formulate this Chinese expert consensus on preoperative auxiliary localization techniques for VATS of pulmonary small nodules.

Deficient mismatch repair(dMMR)is currently recognized as a biomarker for predicting the efficacy of immune checkpoint inhib-itors(ICIs),and domestic and foreign guidelines recommend first-line immunotherapy for patients with solid dMMR tumors.For rectal can-cer,only 5%of patients are classified as dMMR/microsatellite instability-high(MSI-H),and most have"immune desert type"or mismatch re-pair proficient(pMMR)/microsatellite stabilization(MSS)diseases,which respond poorly to ICIs.Therefore,recently,the synergistic effect of immune drugs and neoadjuvant chemoradiotherapy has been the focus of basic and clinical research.An increasing number of clinical trials of phase Ⅱ/Ⅲ immuno-total neoadjuvant therapy(iTNT)have emerged,and the management of locally advanced rectal cancer(LARC)has begun to enter the non-operative treatment era.Furthermore,an increasing number of studies support the efficacy of neoadjuvant immun-otherapy in patients with dMMR/MSI-H LARC,which exempts such patients from surgery and chemoradiotherapy as follow-up treatment and results in a pivot in the treatment paradigm of a watch-and-wait strategy.Regarding the LARC with pMMR/MSS,the preliminary iTNT findings support ICIs as a shift from an initial posterior-line palliative scheme to a first-line selection strategy and the continuation of large-scale clinical trials.However,no definitive conclusion has been reached regarding the best iTNT application for LARC.Recent studies have shown that short-course radiotherapy and sequential neoadjuvant chemotherapy,combined with immunotherapy,can achieve good short-term outcomes.Finally,identifying other new biomarkers may facilitate the identification of patients with pMMR/MSS who are sensitive to immune drugs(especially for low rectal cancer).In the future,the treatment strategy of LARC should be combined with the stratification of clinical recurrence risk and patient willingness for organ retention to achieve stratified and accurate treatment.This article will review the re-lated research background,basic and clinical research progress and existing problems of iTNT in LARC.

In order to promote the development of grassroots hospitals through targeted assistance,ZhuJiang Hospital of Southern Medical University took the lead in responding in Guangdong Province and established a tight-ly-knit specialty alliance belonging to Zhujiang.It introduces the construction content,principles and measures of Zhujiang Tightly-Knit Specialty Alliance,and proposes a dual-promotion management model for the tightly-knit Spe-cialty Alliance.A comprehensive comparison of the changes in specialized technical capabilities and medical quality of Guangning County People's Hospital before and after aid shows that the close specialist alliance has achieved initial results in effectively promoting the sinking of resources and improving the medical technology capabilities and quality of member units.It is of great practical significance for further promoting the development of specialist alliances and filling the shortcomings of primary medical institutions.

Objective To investigate renal expression level of STING in mice with renal ischemia-reperfusion injury(IRI)and its regulatory role in IRI.Methods C57BL/6 mice were divided into sham operation group,IRI(induced by clamping the renal artery)model group,IRI+DMSO treatment group,and IRI+SN-011 treatment group.Serum creatinine and blood urea nitrogen of the mice were analyzed,and pathological changes in the renal tissue were assessed with PAS staining.RT-qPCR,ELISA,Western blotting,and immunohistochemistry were used to detect the expression levels of STING,KIM-1,Bcl-2,Bax,caspase-3,TLR4,P65,NLRP3,caspase-1,CD68,MPO,IL-1β,IL-6,and TNF-α in the renal tissues.In the cell experiment,HK-2 cells exposed to hypoxia-reoxygenation(H/R)were treated with DMSO or SN-011,and cellular STING expression levels and cell apoptosis were analyzed using RT-qPCR,Western blotting or flow cytometry.Results In C57BL/6 mice,renal IRI induced obvious renal tissue damage,elevation of serum creatinine and blood urea nitrogen levels and renal expression levels of KIM-1,STING,TLR4,P65,NLRP3,caspase-1,caspase-3,Bax,CD68,MPO,IL-1β,IL-6,and TNF-α,and reduction of Bcl-2 expression level.Treatment of the mouse models with SN-011 for inhibiting STING expression significantly alleviated these changes.In HK-2 cells,H/R exposure caused significant elevation of cellular STING expression and obviously increased cell apoptosis rate,which was significantly lowered by treatment with SN-011.Conclusion Renal STING expression is elevated in mice with renal IRI to exacerbate renal injury by regulating the TLR4/NF-κB/NLRP3 pathway and promoting inflammation and apoptosis in the renal tissues.
