Neuropathic pain, a debilitating condition caused by dysfunction of the somatosensory nervous system, remains difficult to treat due to limited understanding of its molecular mechanisms. Bioinformatics analysis identified cerebellin 2 (CBLN2) as highly enriched in human and murine proprioceptive and nociceptive neurons. We found that CBLN2 expression is persistently upregulated in dorsal root ganglia (DRG) following spinal nerve ligation (SNL) in mice. In addition, transcription factor SOX11 binds to 12 cis-regulatory elements within the Cbln2 promoter to enhance its transcription. SNL also induced SOX11 upregulation, with SOX11 and CBLN2 co-localized in nociceptive neurons. The siRNA-mediated knockdown of Sox11 or Cbln2 attenuated SNL-induced mechanical allodynia and thermal hyperalgesia. High-throughput sequencing of DRG following intrathecal injection of CBLN2 revealed widespread gene expression changes, including upregulation of numerous NF-κB downstream targets. Consistently, CBLN2 activated NF-κB signaling, and inhibition with pyrrolidine dithiocarbamate reduced CBLN2-induced pain hypersensitivity, proinflammatory cytokines and chemokines production, and neuronal hyperexcitability. Together, these findings identified the SOX11/CBLN2/NF-κB axis as a critical mediator of neuropathic pain and a promising target for therapeutic intervention.

Hongsheng Dan, historically referred to as the "surgical sacred medicine", is at risk of losing its refining technology in contemporary times. This study aimed to preserve and innovate this traditional non-heritage refining technology. By utilizing the analytic hierarchy process(AHP) combined with the entropy weight method, this study established the hierarchical structure model of refining process of Hongsheng Dan and conducted a single factor experiment and an L_9(3~4) orthogonal experiment to optimize the refining method of Hongsheng Dan. Additionally, the study employed infrared thermal imaging to monitor temperature variations of Hongsheng Dan during the refining process. The optimized refining parameters for Hongsheng Dan were established as follows: a slow fire temperature of 175 ℃ with a duration of 30 minutes, a strong fire temperature of 270 ℃ with a duration of 60 minutes, and a tail fire temperature of 180 ℃ with a duration of 15 minutes. The stability and feasibility of this optimized process were confirmed through validation tests. The research focused on the material transformation of Hongsheng Dan, starting from the material changes during the refining process of Hongsheng Dan and the synthesis of mercuric oxide from nitric acid. The study investigated elemental transformations, physical phase changes, and alterations in thermal properties. 78.98% of the mercury in Hongsheng Dan and 80.21% of the mercury in mercuric oxide from nitric acid were retained. The diffraction peak intensity of the(011) crystal plane of Hongsheng Dan was highest at approximately 30.07°, indicating that the(011) crystal plane had a preferred crystalline orientation. Furthermore, the temperature range for the alteration in thermal properties during the refining process of Hongsheng Dan was found to be between 80 ℃ and 130 ℃. This research not only optimized the refining technology of Hongsheng Dan but also pioneered the application of infrared thermal imaging to study temperature changes throughout the refining process. By exploring the material transformation patterns of Hongsheng Dan and the synthesis of mercuric oxide from nitric acid, the study provided technical support for the preservation and innovation of Hongsheng Dan.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective To explore the inhibitory effect of guggulsterone(GS)on diethylnitrosamine(DEN)-induced liver fibrosis in rats and its mechanism.Methods DEN-induced liver fibrosis model was established in SD rats.The successful model rats were randomly divided into model group(n=6),GS group(n=6,50 mg/kg,intraperitoneal injection for 4 weeks),GS+SRI group(n=6,50 mg/kg+30 mg/kg,intraperitoneal injection for 4 weeks),and control group(n=6,without DEN-induced).Rats in the control group and the model group were injected with the same amount of normal saline.The pathological changes of the liver were detected by HE staining.Serum liver function indexes including alanine aminotransferase(ALT),aspartate aminotransferase(AST),albumin(ALB)and alkaline phosphatase(ALP)were detected by automatic biochemical analyzer.The serum levels of pro-collagen Ⅲ(PC-Ⅲ),collagen Ⅳ(Ⅳ-C),hyaluronidase(HA),laminin(LN),malondialdehyde(MDA),reduced glutathione(GSH),superoxide dismutase(SOD),and catalase(CAT)were detected by ELISA assay.The mRNA and protein expression of TGF-β1,Smad2,and p-Smad3/Smad3 were detected by Real-time PCR and Western blotting.Results Compared with the control group,the model group showed typical pathological changes of liver fibrosis;the serum ALB,GSH,SOD and CAT levels were significantly decreased(P＜0.05);the serum levels of ALT,AST,ALP,MDA,PC-Ⅲ,Ⅳ-C,HA,LN and the mRNA expression of TGF-β1,Smad3 and protein expression of TGF-β1,p-Smad3 in liver tissues were significantly increased(P＜0.05).Compared with the model group,the pathological changes of liver fibrosis in the GS group were alleviated,and the serum levels of ALB,GSH,SOD and CAT were significantly increased(P＜0.05),the serum levels of ALT,AST,ALP,MDA,PC-Ⅲ,Ⅳ-C,HA and LN,the mRNA expression of TGF-β1 and Smad3,and protein expression of TGF-β1 and p-Smad3 in liver tissues were significantly decreased(P＜0.05).In addition,after the administration of SRI,TGF-β1 signaling pathway activator,compared with the GS group,the GS+SRI group showed significantly decreased serum ALB,GSH,SOD and CAT levels(P＜0.05),but significantly increased serum levels of ALT,AST,ALP,MDA,PC-Ⅲ,Ⅳ-C,HA and LN as well as the mRNA expression of TGF-β1 and Smad3 and protein expression of TGF-β1 and p-Smad3 in liver tissues(P＜0.05).Therefore,SRI attenuated the anti-fibrotic effect of GS on rats with liver fibrosis.Conclusion GS has certain inhibitory effect on DEN-induced liver fibrosis in rats,and its mechanism may be related to the reduction of oxidative stress level and the inhibition of the activation of TGF-β1/Smad3 signaling pathway.

Objective: Self-determination theory (SDT) deems that people have three causality orientations: autonomy orientation, control orientation, and impersonal orientation. Previous studies suggested that lower autonomy orientation or higher control and impersonal orientations may be associated with more addictive behaviors. Our study aimed to investigate if these associations exist in Internet gaming disorder (IGD), and if sensation seeking, anxiety, and depression could influence the associations between causality orientations and IGD symptoms. Methods: A total of 1,400 college students completed the Internet Gaming Disorder Scale, General Causality Orientation Scale, Brief Sensation Seeking Scale, Generalized Anxiety Disorder Scale, and Patient Health Questionnaire. Correlation, multiple linear regressions, structural equation model (SEM) analyses, and moderation analyses were conducted to explore the associations. Results: The control and impersonal orientations were positively associated with IGD symptoms, while the autonomy orientation was negatively associated with them. Moreover, SEM analyses showed that the autonomy-IGD relationship was totally mediated by anxiety and depression, the impersonal-IGD relationship was partially mediated by anxiety, and the control-IGD relationship was partially mediated by depression. Finally, the effects of causality orientations on IGD were moderated by sensation seeking. Conclusion Overall, autonomy orientation is linked to fewer gaming problems, whereas control and impersonal orientations are associated with more gaming problems. Moreover, the relationships between causality orientations and IGD symptoms are mediated by anxiety and depression and moderated by sensation seeking. Our findings inform theory on the motivations of gaming behaviors and may shed light on the prevention and intervention of IGD from the perspective of SDT.

Objective:To investigate the causal correlation between depression and stress urinary incontinence(SUI)using Mendelian randomization(MR)analysis.Methods:We searched the FinnGen Consortium database for genome-wide association studies(GWAS)on depression and obtained 23 424 case samples and 192 220 control samples,with the GWAS data on SUI provided by the UK Biobank,including 4 340 case samples and 458 670 control samples.We investigated the correlation between depression and SUI based on the depression data collected from the Psychiatric Genomics Consortium(PGC).We employed inverse-variance weighting as the main method for the MR study,and performed sensitivity analysis to verify the accuracy and stability of the findings.Results:Analysis of the data from the UK Biobank and FinnGen Consortium showed that depression was significantly correlated with an increased risk of SUI(P=0.005),but not SUI with the risk of depression(P=0.927).And analysis of the PGC data verified the correlation of depression with the increased risk of SUI(P=0.043).Conclusion:Depression is associated with an increased risk of SUI,while SUI does not increase the risk of depression.
