Lupus nephritis (LN), one of the most severe complications of systemic lupus erythematosus (SLE), has a complex pathogenesis involving various endogenous factors including autoimmune complex deposition, inflammatory cell infiltration, and cellular damage. Recent research has increasingly highlighted the prominent role of inflammasomes, particularly the nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3) inflammasome, in LN pathogenesis. Substantial evidence has confirmed its significant role in both the onset and progression of LN. Given that the NLRP3 inflammasome is a critical factor in triggering and exacerbating LN, its mechanism of action warrants in-depth exploration. Furthermore, research on intervention strategies targeting the NLRP3 inflammasome to ameliorate LN is of great significance. This article reviews the latest advances in the role of the NLRP3 inflammasome in LN pathogenesis and related intervention studies, which may offer new insights for the clinical diagnosis and treatment of LN.

Objective:To assess the efficacy and safety of pain control nursing for burn patients.Methods:Databases including CNKI, Wanfang Data Knowledge Service Platform, Weipu Database, China Biomedical Literature Database, Web of Science and Cochrane Library were searched to collect the literature on pain control nursing of burn patients from their inception to December 31, 2024. Literature screening, data extraction and quality assessment were performed independently by 2 researchers based on inclusion and exclusion criteria. Meta-analysis of the included studies was performed by applying RevMan 5.4 software. The efficacy of pain control care was assessed in terms of improving care satisfaction, alleviating negative emotions, reducing pain, and decreasing infection rate. Publication bias was analyzed on the related studies.Results:A total of 9 papers were included, all of which were randomized controlled trial (RCT) studies, involving 791 burn patients, with 392 in the pain control nursing group and 399 in the conventional care group. Meta-analysis showed that compared with the conventional care, pain control nursing significantly increased satisfaction of care ( OR=0.28, 95% CI 0.22, 0.34), improved negative emotions ( SMD=-3.06, 95% CI -4.65, -1.47), reduced pain ( SMD=-2.49, 95% CI -3.41, -1.58), and effectively reduced the incidence of infection ( OR=0.13, 95% CI 0.05, 0.34). The studies related to negative emotions were at the risk of publication bias. Conclusion:Compared with conventional care, pain control nursing can significantly increase care satisfaction, alleviate negative emotions, reduce pain, and lower infection risk in burn patients.

Objective:To explore the characteristics of the brain functional networks in children with spastic cerebral palsy (SCP) while at rest and to correlate them with motor functioning.Methods:Thirty-six children with SCP were enrolled as the SCP group, while thirty-four age-matched healthy children were recruited as the control group (the HC group). Functional near-infrared spectroscopy was used to detect changes in the concentration of oxygenated hemoglobin in the children′s cerebral cortex while at rest. The left prefrontal cortex (LPFC), right prefrontal cortex (RPFC), left motor cortex (LMC), and right motor cortex (RMC) were selected as regions of interest. Phase locking values (PLVs) were used to evaluate the strength of functional connectivity (FC) among these brain regions, and graph theory methods were applied to analyze the topological properties of the brain networks. Motor functioning was assessed using the gross motor function measure (GMFM).Results:The analyses of FC strength revealed that the SCP group had significantly weaker FC among all of the regions of interest while at rest compared to the HC group. Their PLVs for LPFC-RPFC, LPFC-RMC, RPFC-RMC and LMC-RMC connectivity were all significantly smaller. Graph theory analysis showed that the SCP group had significantly lower global efficiency (GE) and smaller clustering coefficients (CCs) and network density (D), while their characteristic path lengths were significantly longer. According to the correlation analysis, the PLVs for LMC-RMC connections in the SCP group were positively correlated with their scores on dimensions D and E of the GMFM ( r=0.496 and r=0.579 respectively). GE ( r=0.587 and r=0.642) and CC ( r=0.318 and r=0.759) showed similar significant positive correlations with GMFM dimensions D and E. Conclusions:At rest, the functional networks in the brains of children with SCP exhibit abnormalities closely associated with their motor dysfunction.

Objective:The clinicalpathological features of TAFRO syndrome were analyzed to clarify the similarities and differences between TAFRO syndrome and autoimmune diseases and to establish differential diagnosis.Methods:Six patients diagnosed with TAFRO syndrome in Shanxi Bethune Hospital from January 2014 to March 2022 were collected. The clinical, examination, pathology and treatment of TAFRO syndrome were analyzed and compared with autoimmune diseases, especially systemic lupus erythematosus and Sj?gren′s syndrome.Results:Among the 6 patients, 4 were males and 2 were females, with an average age of (57.5 ±9.8) years. All the 6 patients had fever, edema (including chest and abdominal effusion and systemic edema), thrombocytopenia (3 main criteria) and more than 2 secondary criteria.ESR and CRP were significantly elevated in 6 patients. There were 1 case of elevated IgA and IgG (IgA 4.10 g/L, IgG19.05 g/L), 1 case of elevated igg (IgG 19.33 g/L), 3 cases of normal and 1 case of undetected. Serum IgG4 was negative in 4 cases and undetected in 2 cases. Autoantibodies: 4 cases were ANA positive, including 1 case with anti-SSA/Ro52(+), anti-SSA/Ro60(+), anti-SSB (+), 1 case with anti-SSA /Ro60(+), and 2 untested. Bone marrow cytological examination was performed in 6 cases, all of which showed active hyperplasia, 2 cases showed elevated megakaryocytes, and 1 case was accompanied by interstitial fibrosis. Pathological examination of lymph nodes: 5 cases were consistent with Castleman′s disease, and 1 case was suggestive of reactive hyperplasia of lymph nodes. Conclusion:Although the diagnostic criteria of TAFRO syndrome should exclude autoimmune diseases, TAFRO syndrome and autoimmune diseases can coexist, and the connective tissue disease complicated with TAFRO syndrome has its specific clinical characteristics and treatment plan, which needs to be identified clinically.

Objective:Using Mendelian randomization analysis to investigate the unidirectional causal effects of gut microbiota on gout and serum uric acid levels.Methods:The Mendelian randomization analysis was conducted using summary statistics from genome-wide association studies (GWAS). The gut microbiota was used as the exposure factor, with gout and serum uric acid levels as the outcomes, utilizing the MiBioGen Consortium, FinnGen GWAS, and CKDGen Consortium meta-analysis databases. The analysis was performed using inverse variance weighted (IVW) method, MR-Egger, and weighted median (WM) approach. Additionally, sensitivity analysis was conducted by excluding heterogeneity and horizontal pleiotropy. This study used RStudio 4.3.1 software for analysis.Results:The IVW results confirmed that 17 microbiota taxa were associated with gout, including class Verrucomicrobiaceae [ OR(95% CI)=1.162(1.004, 1.344), P=0.044], family Verrucomicrobiaceae [ OR(95% CI)=1.161(1.004, 1.344), P=0.044], genus Akkermansia [ OR(95% CI)=1.162(1.004, 1.344), P=0.044], genus Collinsella [ OR(95% CI)=1.257(1.043, 1.516), P=0.016], genus Eubacterium hallii group [ OR(95% CI)=1.226(1.022, 1.471), P=0.027], genus Howardella [ OR(95% CI)=1.094(1.001, 1.195), P=0.046], genus Ruminococcaceae UCG010 [ OR(95% CI)=1.317(1.089, 1.593), P=0.004], order Clostridiales [ OR(95% CI)=1.182(1.007,1.387), P=0.041], order Verrucomicrobiales [ OR(95% CI)=1.162(1.004, 1.344), P=0.044], class Melainabacteria [ OR(95% CI)=0.894(0.804, 0.994), P=0.038], family Streptococcaceae [ OR(95% CI)=0.851(0.727, 0.996), P=0.044], unknown family [ OR(95% CI)=0.890(0.800, 0.989), P=0.030], genus Streptococcus [ OR(95% CI)=0.836(0.710, 0.983), P=0.030], unknown genus [ OR(95% CI)=0.890(0.800, 0.989), P=0.030], genus Victivallis [ OR(95% CI)=0.857(0.736, 0.998), P=0.046], order Gastranaerophilales [ OR(95% CI)=0.890(0.800,0.989), P=0.030], and phylum Bacteroidetes [ OR(95% CI)=0.827(0.692, 0.989), P=0.037].

Objective:To investigate the prevalence and distribution of childhood maltreatment, internet addiction, and emotional and behavioral problems among middle school students in Guangzhou, and to explore the relationship between childhood maltreatment and internet addiction and the mediating role of emotional and behavioral problems.Methods:A total of 1 957 students from 10 middle schools in Guangzhou were recruited using multistage cluster random sampling and were investigated with anonymous questionnaires including the general demographic data, the Childhood Trauma Questionnaire-Short form (CTQ-SF), the Internet Addiction Test (IAT) and the Strengths and Difficulties Questionnaire (SDQ). Linear regression analysis was conducted to explore the relationship between childhood maltreatment and internet addiction, and the Bootstrap approach was used to reveal the potential mediating effect of emotional and behavioral problems on the relationship between childhood maltreatment and internet addiction.Results:The prevalence of internet addiction among middle school students in Guangzhou was 14.4%(270/1 873), and the median ( IQR) score for IAT was 33 (16). The linear regression analysis revealed that after adjusting for potential confounders, trauma exposure (β=2.217, P<0.001) and abuse exposure (β=4.689, P<0.001) were positively associated with internet addiction. Bootstrap approach and path analysis showed that there was a partial mediating effect of internal problems (β=0.305, 95% CI=0.154-0.480) and external problems (β=1.306, 95% CI=0.992-1.667) on the relationship between trauma exposure and internet addiction. Meanwhile, internal problems (β=0.413, 95% CI=0.185-0.678) and external problems (β=1.835, 95% CI=1.338-2.379) also partially mediate the relationship between abuse exposure and internet addiction. Conclusion:There is a relatively high prevalence of internet addiction among middle school students in Guangzhou. Childhood maltreatment is a risk factor for internet addiction among middle school students, and there is a partial mediating effect of emotional and behavioral problems.
