This study examined the effect of islet macrophages on β-cell function changes during type 2 diabetes mellitus (T2DM) progression based on the traditional Chinese medicine theory that " moderate fire generating qi, hyperactive fire consuming qi" . T2DM is closely associated with chronic low-grade inflammation, with islet macrophages playing a central role in this process. Under physiological conditions, islet macrophages secrete anti-inflammatory and growth factors to regulate the immune response, promote cell proliferation, and support islet β-cell survival and function, reflecting the concept of " moderate fire generating qi" . However, during the pathological process of T2DM, islet macrophages become over-activated and dysfunctional, secreting large amounts of pro-inflammatory factors that trigger severe inflammatory responses and oxidative stress. This process damages islet β-cells, disrupts the islet microenvironment and blood supply, exacerbates local inflammation and structural damage, and worsens the survival environment of β-cells. Ultimately, this leads to fewer β-cells and function loss, aligning with the " hyperactive fire consuming qi" theory, where excessive fire depletes qi and blood. This study enhances the understanding and application of traditional Chinese medicine theories in modern medicine, offering a new perspective on T2DM prevention and treatment. Regulating islet macrophage function and reducing their pro-inflammatory responses may become key strategies for preserving β-cell function and slowing T2DM progression.

Hepatic encephalopathy (HE) is a common complication of severe liver disease in the end stage, and it is urgently needed to improve the rate of effective treatment and clarify the pathogenesis of HE. The liver is a crucial hub for immune regulation, and disruption of immune homeostasis is a key factor in the pathological mechanisms of HE. As the main metabolites of intestinal flora, short-chain fatty acids (SCFAs) play a vital role in the biological processes of both innate and adaptive immunity and can regulate the proliferation and differentiation of immune cells maintain the homeostasis of intestinal microenvironment and the integrity of barrier function. Studies have shown that SCFAs participate in bidirectional and dynamic interactions with the liver-gut-brain axis through immunomodulatory pathways, thereby playing an important role in the diagnosis, treatment, and prognostic evaluation of HE. Starting from the immunoregulatory effect of SCFAs, this article summarizes and analyzes the crosstalk relationship between SCFAs and the liver-gut-brain axis and the significance of SCFAs in the diagnosis and treatment of HE, in order to provide new ideas for optimizing clinical prevention and treatment strategies.

Objective:
To evaluate the efficacy and safety of Jiawei Simiao powder (JWSMP) combined with celecoxib for the treatment of acute gouty arthritis by conducting a meta-analysis of randomized controlled trials (RCTs).
Methods:
The Chinese National Knowledge Infrastructure Databases, Chinese Scientific Journal Database, Wanfang, Cochrane Library, EMBASE, PubMed, and Web of Science databases were searched from inception until December 2023. Continuous variables were analyzed using the mean difference (MD) for analysis, and dichotomous variables were used as risk ratios. Data with similar characteristics were pooled for meta-analysis, and heterogeneity was assessed using I2. The Cochrane Handbook was used to assess the risk of bias and quality. RevMan 5.3 software was used to perform the meta-analysis.
Results:
Thirteen RCTs involving 1007 patients were included in the study. The quality of the included studies was low (unclear randomization processes and insufficient blinding reporting). The group receiving JWSMP combined with celecoxib showed significantly lower levels of serum uric acid (SUA, MD = −66.32, 95% confidence interval (CI): −80.97 to −51.67, P < .001), erythrocyte sedimentation rate (ESR, MD = −6.05, 95% CI: −8.29 to −3.82, P < .001), C-reactive protein (CRP, MD = −7.39, 95% CI: −11.15, −3.63, P < .001), and joint pain score (VAS score, MD = −2.14, 95% CI: −2.4 to −1.88, P < .001) compared to celecoxib alone. Additionally, the JWSMP combined group had a higher total effective rate (risk ratio = 1.22, 95% CI: 1.14 to 1.29, P < .001) and fewer adverse compared to celecoxib alone.
Conclusions
JWSMP combined with celecoxib is more effective than celecoxib alone in improving the total efficacy rate, alleviating joint pain, and improving SUA, ESR, and CRP levels. JWSMP also reduced the occurrence of adverse events caused by celecoxib. However, the quality of the included studies was low, highlighting the need for further high-quality research with larger sample sizes and robust methodologies, such as double-blind randomization, to confirm these findings.

Objective:To investigate the role of TcpC, a virulence factor of uropathogenic Escherichia coli (UPEC), in immune evasion, and analyze its related pathogenic mechanism. Methods:C57BL/6 mice were injected with 10 9 colony-forming unit of wild-type (CFT073 wt) or tcpc gene-knockout (CFT073 Δ tcpc) UPEC CFT073 strains from urethra into bladder to construct a mouse model of pyelonephritis. These mice were sacrificed 5 d after infection and their kidneys were taken to observe the gross pathological changes. Hematoxylin-eosin staining was used to observe histopathological changes in kidney tissues and immunohistochemistry was performed to locate TcpC in kidney tissues. The bacterial loads in urine samples of UPEC infected-mice were counted by ten-fold dilution method, and the presence of tcpc gene in the genomic DNA of bacteria from CFT073-infected mouse kidney or urine samples was measured by PCR. The expression of TcpC at mRNA level was detected by qRT-PCR after infecting dendritic cells with CFT073 wt strains. The influences of UPEC infection on the activation of NF-κB signaling pathway and the secretion of proinflammatory factors by dendritic cells were analyzed by Western blot and ELISA, respectively. The viability of UPEC strains in dendritic cells were observed by laser confocal microscope. Results:Compared with the CFT073 Δ tcpc group, the mice in the CFT073 wt group had obvious abscess in the kidneys as well as massive neutrophil infiltration and abundant TcpC in kidney tissues. The bacterial loads in the urine of CFT073 wt-infected mice were significantly higher than those in the urine of CFT073 Δ tcpc mice. PCR results showed that tcpc gene was successfully amplified from mouse kidney and urine samples. Increased expression of TcpC at both mRNA and protein levels was detected in CFT073 wt-infected dendritic cells. CFT073 wt infection inhibited the phosphorylation of NF-κB p50 and the production of proinflammatory factors in dendritic cells. TcpC promoted the survival of CFT073 wt in dendritic cells. Conclusions:TcpC expression increases significantly during CFT073 wt infection or in mice with CFT073 wt-induced pyelonephritis. It promotes the survival of CFT073 wt in dendritic cells by inhibiting the activation of NF-κB signaling pathway and reducing the secretion of pro-inflammatory cytokines. TcpC is involved in the pathogenesis of UPEC and immune evasion.

ObjectiveTo explore the relationships between internet gaming disorder (IGD), interpersonal needs, loneliness, and depression in adolescents through the construction of a chain mediation model, to clarify the underlying mechanisms of these associations, and to provid a theoretical basis for depression prevention and intervention. MethodsBased on the data of the 7th Population Census, using convenient sampling method 1 106 adolescents aged between 10‒19 years in South China (176), North China (147), Central China (332), and East China (451) were selected to conduct a cross-sectional survey, with a ratio of 1∶1∶1.5∶2.5. The survey was conducted with a questionnaire consisting of general information (sex, age, grade, parents’ education level), the Chinese version of the IGDS9-SF, the INQ-15, the short-form of the ULS-8 and the PHQ-9 were used to evaluate the depression status of adolescents. Spearman correlation analysis was used to explore the correlation between the variables. A multiple-mediator model was constructed using IBM SPSS Statistics 22.0 PROCESS to examine the mediating effects of interpersonal needs and loneliness on the relationship between IGD and depression. The significance of the chain mediating effect was tested using the Bootstrap method. ResultsOverall, 39.06% (432/1 106) adolescents experienced depression. The incidence of depression among adolescents with smoking and without smoking was 62.50% and 38.36%, respectively. Similarly, the incidence of depression among adolescents with alcohol consuming and without alcohol consuming was 61.94% and 35.94%, respectively. There were statistically significant differences between IGD, interpersonal needs, loneliness, and depression (P<0.01). The chain mediation model demonstrated a good fit, and the bootstrap test showed that the 95%CI of each mediation path did not include 0, indicating significant mediation effects. The overall effect was 0.337. The direct effect of IGD on depression was significant (effect value=0.138, 95%CI:0.102-0.173, P<0.001). The mediation effects included three paths: ① IGD →interpersonal needs → depression (effect value=0.073, P<0.05), accounting for 21.47% of the total effect;② IGD→ loneliness → depression (effect value=0.093, P<0.05), accounting for 27.35%; and ③ IGD → interpersonal needs → loneliness → depression (effect value=0.036, P<0.05), accounting for 10.59%. ConclusionInterpersonal needs and loneliness independently and jointly mediate the relationship between IGD and depression among adolescents. To reduce depression and improve mental health in this population, measures should be taken to prevent and intervene in IGD, address adolescents’ social and emotional needs, enhance satisfaction of interpersonal needs, and reduce loneliness.

Pseudorabies virus (PRV) is a porcine herpesvirus that exhibits cross-species infectivity, primarily affecting pigs as its natural host. Since its initial discovery, PRV has rapidly disseminated worldwide and inflicted substantial economic losses on the swine industry. In recent years, sporadic cases of human infections with PRV have been reported, highlighting the potential risk of interspecies transmission to humans. With further analysis of the pathogenic characteristics of PRV and a deeper understanding of its pathogenic mechanism, preventing PRV from becoming a human infectious disease has become a focus of current research and prevention and control work. To comprehensively understand the variant characteristics of PRV, this study presents an overview of cutting-edge advancements in terms of its genetic variations and epidemiological characteristics, aiming to establish a foundation for more effective implementation of relevant prevention and control work.
