This comprehensive review synthesizes the latest advancements in understanding inflammatory disorders affecting cerebral small vessels, a distinct yet understudied category within cerebral small vessel diseases (SVD). Unlike classical SVD, these inflammatory conditions exhibit unique clinical presentations, imaging patterns, and pathophysiological mechanisms, posing significant diagnostic and therapeutic challenges. Highlighting their heterogeneity, this review spans primary angiitis of the central nervous system, cerebral amyloid angiopathy-related inflammation, systemic vasculitis, secondary vasculitis, and vasculitis in autoinflammatory diseases. Key discussions focus on emerging insights into immune-mediated processes, neuroimaging characteristics, and histopathological distinctions. Furthermore, this review underscores the importance of standardized diagnostic frameworks, individualized immunomodulation approaches, and novel targeted therapies to address unmet clinical demands.

Acute lung injury (ALI) is a severe disease caused by viral infection that triggers an uncontrolled inflammatory response. This study investigated the capacity of jasurolignoside (JO), a natural compound, to bind to Toll-like receptor 4 (TLR4) and treat ALI. The anti-inflammatory properties of JO were evaluated in vitro through Western blotting, enzyme-linked immunosorbent assay (ELISA), immunofluorescence staining, and co-immunoprecipitation. The investigation utilized a lipopolysaccharide (LPS)-induced ALI animal model to examine the therapeutic efficacy and mechanism of JO in vivo. JO attenuated inflammatory symptoms in infected cells and tissues by modulating the NOD-like receptor family pyrin domain containing protein 3 (NLRP3) inflammasome and the nuclear factor κB (NF-κB)/mitogen-activated protein kinase (MAPK) pathway. Molecular docking simulations revealed JO binding to TLR4 active sites, confirmed by cellular thermal shift assay. Surface plasmon resonance (SPR) demonstrated direct interaction between JO and TLR4 with a Kd value of 35.1 μmol·L-1. Moreover, JO inhibited tumor necrosis factor α (TNF-α), interleukin-1β (IL-1β), and IL-6 secretion and reduced leukocyte, neutrophil, lymphocyte, and macrophage infiltration in ALI-affected mice. JO also enhanced lung function and reduced ALI-related mortality. Immunohistochemical staining demonstrated JO's ability to suppress TLR4 expression in ALI-affected mouse lung tissue. This study establishes that JO can bind to TLR4 and effectively treat ALI, indicating its potential as a therapeutic agent for clinical applications.

Objective To compare the effects of different axillary lymph node surgical procedures on complications following immediate two-stage breast reconstruction after mastectomy.Methods A retrospective analysis was performed on 232 patients who underwent mas-tectomy with immediate two-stage breast reconstruction in the Department of Breast Surgery at the First Hospital of China Medical Uni-versity between January 2018 and December 2021.Patients were divided into two groups based on the type of axillary lymph node surgery performed:the sentinel lymph node biopsy group(SLNB group,n=84)and the axillary lymph node dissection group(ALND group,n=148).We compared baseline characteristics,surgical procedures,and postoperative complications between the two groups.Results The ALND group had a higher prevalence of advanced T and N stages,received neoadjuvant chemotherapy more frequently,and underwent chemotherapy and radiotherapy at a higher rate compared to the SLNB group.Additionally,the ALND group experienced greater drainage volume and a significantly higher complication rate(all P<0.05).Postoperative infection was the most common complication observed in the ALND group.Importantly,no significant differences were found in long-term outcomes(local/regional recurrence,distant metastasis,and disease-free survival)between the two groups(all P>0.05).Conclusion In patients undergoing immediate two-stage breast recon-struction after mastectomy,axillary lymph node dissection is associated with a higher rate of reconstruction complications compared to sentinel lymph node biopsy.

AIM:To compare the risk of hypergly-caemia with PCSK9 inhibitors versus statins,based on U.S.Food and Drug Administration Adverse Events Reporting System(FAERS).METHODS:The hyperglycaemia reports induced by"alirocumab","evolocumab","atorvastatin"and"rosuvastatin"were utilized as the first suspected drugs from the database of FAERS from 2016 to the third quarter of 2023.The report odd ratio(ROR)method was employed.RESULTS:Based on the FAERS database,the ROR(95%CI)for hyperglycaemia due to Ali-rocumab versus Atorvastatin and Rosuvastatin were 0.628(0.545,0.724)and 0.307(0.263,0.357),the ROR(95%CI)for hyperglycaemia due to Evoloc-umab were 0.817(0.750,0.889)and 0.399(0.361,0.441),all generated no adverse reaction signals.The ROR(95%CI)for hyperglycaemia due to Ali-rocumab and Evolocumab versus all other drugs in FAERS were 1.488(1.315,1.682)and 1.934(1.845,2.027),all generated adverse reaction signals,re-spectively.CONCLUSION:Based on the FAERS data-base,PCSK9 inhibitors have a lower risk of hyper-glycemia than statins and deserve clinical attention.

Objective:
Imaging parameters of Chiari malformation type I (CMI) development are not well established. This study aimed to collect evidence of general or specific imaging measurements in patients with CMI, analyze indicators that may assist in determining the severity of CMI, and guide its diagnosis and treatment.
Methods:
A comprehensive search was conducted across various databases including the Cochrane Library, PubMed, MEDLINE, Scopus, and Embase, covering the period from January 2002 to October 2023, following predefined inclusion criteria. Meta-analyses were performed using RevMan (ver. 5.4). We performed a quantitative summary and systematic analysis of the included studies. This study was registered in the PROSPERO (International Prospective Register of Systematic Reviews) prior to initiation (CRD42023415454).
Results:
Thirty-three studies met our inclusion criteria. The findings indicated that out of the 14 parameters examined, 6 (clivus length, basal angle, Boogard’s angle, supraocciput lengths, posterior cranial fossa [PCF] height, and volume) exhibited significant differences between the CMI group and the control group. Furthermore, apart from certain anatomical parameters that hold prognostic value for CMI, functional parameters like tonsillar movement, obex displacement, and cerebrospinal fluid dynamics serve as valuable indicators for guiding the clinical management of the disease.
Conclusion
We collated and established a set of linear, angular, and area measurements deemed essential for diagnosing CMI. However, more indicators can only be analyzed descriptively for various reasons, particularly in prognostic prediction. We posit that the systematic assessment of patients’ PCF morphology, volume, and other parameters at a 3-dimensional level holds promising clinical application prospects.
