ObjectiveTo investigate the mechanism of Tangbikang dry paste in the prevention and treatment of type 2 diabetic peripheral neuropathy (DPN) based on the glyoxalase-1 (GLO-1)/advanced glycation end products (AGE)/receptor for advanced glycation end products (RAGE) pathway. MethodsA total of 56 Sprague-Dawley rats were randomly divided, with eight assigned to the normal group. The remaining 48 rats were fed a high-fat diet combined with intraperitoneal injection of streptozotocin (STZ) to induce a type 2 diabetes mellitus (T2DM) model. Based on blood glucose levels, the rats were randomly assigned to the model group, Tanglin group (13.5 mg·kg-1), metformin group (135 mg·kg-1), and Tangbikang dry paste low-, medium-, and high-dose groups (3, 6, 12 g·kg-1). Successful modeling of DPN was confirmed by a decrease in mechanical pain threshold in the model group at week 4. Fasting blood glucose, body weight, and mechanical pain threshold were measured every 4 weeks. After 16 weeks of intervention, the pathological morphology of the sciatic nerve was observed using hematoxylin-eosin (HE) staining. The expression of RAGE, AGE, protein kinase C (PKC), and collagen (COL) in the sciatic nerve was assessed by immunohistochemistry. The mRNA expression of RAGE, PKC, Toll-like receptor (TLR), COL, and GLO-1 was detected using real-time quantitative PCR (Real-time PCR). Serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), urea (UREA), interleukin-6 (IL-6), and tumor necrosis factor (TNF)-α were measured by enzyme-linked immunosorbent assay (ELISA). ResultsCompared with the normal group, the model group showed significantly increased fasting blood glucose (P<0.01), decreased body weight and mechanical pain threshold (P<0.01), and elevated serum AST, ALT, CREA, UREA, IL-6, and TNF-α levels (P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was significantly increased (P<0.01), while COL expression was decreased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was upregulated (P<0.01), whereas COL and GLO-1 mRNA levels were downregulated (P<0.01). Histological examination showed irregular nerve morphology, axonal alterations, and myelin degeneration. Compared with the model group, fasting blood glucose levels in the Tangbikang dry paste high-dose group at all time points and in the medium-dose group at weeks 4 and 16 were significantly reduced (P<0.05, P<0.01). No significant changes in body weight were observed across all Tangbikang dose groups. The mechanical pain threshold was elevated at different time points after administration in all Tangbikang groups (P<0.05, P<0.01). Serum IL-6 and TNF-α levels were decreased in all dose groups (P<0.05, P<0.01). The expression of RAGE, AGE, and PKC in the sciatic nerve was reduced (P<0.01), while COL expression was increased (P<0.01). The mRNA expression of TLR, RAGE, and PKC was downregulated (P<0.01), whereas GLO-1 mRNA expression was upregulated (P<0.05, P<0.01). Additionally, COL mRNA expression was significantly increased in the low- and high-dose groups (P<0.01). Pathological changes in the sciatic nerve were milder in all Tangbikang groups compared to the model group. ConclusionTangbikang dry paste significantly improves DPN, and its mechanism may be associated with the regulation of the GLO-1/AGE/RAGE signaling pathway.

OBJECTIVES:
To report the development, validation, and findings of the Multi-dimensional Attention Rating Scale (MARS), a self-report tool crafted to evaluate six-dimension attention levels.
METHODS:
The MARS was developed based on Classical Test Theory (CTT). Totally 202 highly educated healthy adult participants were recruited for reliability and validity tests. Reliability was measured using Cronbach's alpha and test-retest reliability. Structural validity was explored using principal component analysis. Criterion validity was analyzed by correlating MARS scores with the Toronto Hospital Alertness Test (THAT), the Attentional Control Scale (ACS), and the Attention Network Test (ANT).
RESULTS:
The MARS comprises 12 items spanning six distinct dimensions of attention: focused attention, sustained attention, shifting attention, selective attention, divided attention, and response inhibition.As assessed by six experts, the content validation index (CVI) was 0.95, the Cronbach's alpha for the MARS was 0.78, and the test-retest reliability was 0.81. Four factors were identified (cumulative variance contribution rate 68.79%). The total score of MARS was correlated positively with THAT (r = 0.60, P < 0.01) and ACS (r = 0.78, P < 0.01) and negatively with ANT's reaction time for alerting (r = -0.31, P = 0.049).
CONCLUSIONS
The MARS can reliably and validly assess six-dimension attention levels in real-world settings and is expected to be a new tool for assessing multi-dimensional attention impairments in different mental disorders.

OBJECTIVE:
To investigate the genetic causal relationship of leukocyte telomere length (LTL) with prostatitis, orchitis and epididymitis by two-sample Mendelian randomization (MR).
METHODS:
Using LTL as the exposure factor and prostatitis, orchitis and epididymitis as outcome factors, we mined the Database of Genome-Wide Association Studies (GWAS). Then, we analyzed the causal relationship of LTL with prostatitis, orchitis and epididymitis by Mendelian randomization using inverse variance weighting (IVW) as the main method and weighted median and MR-Egger regression as auxiliary methods, determined the horizontal multiplicity by MR-Egger intercept test, and conducted sensitivity analysis using the leaving-one-out method.
RESULTS:
A total of 121 related single nucleotide polymorphisms (SNPs) were identified in this study. IVW showed LTL to be a risk factor for prostatitis (OR = 1.383, 95% CI: 1.044-1.832, P = 0.024), and for orchitis and epididymitis as well (OR = 1.770, 95% CI: 1.275-2.456, P = 0.000 6).
CONCLUSION
Genetic evidence from Mendelian randomized analysis indicates that shortening of LTL reduces the risk of prostatitis, orchitis and epididymitis.

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.
