Several types of arthritis share the common feature that the generation of inflammatory mediators leads to joint cartilage degradation. However, the shared mechanism is largely unknown. H2BK120ub1 was reportedly involved in various inflammatory diseases but its role in the shared mechanism in inflammatory joint conditions remains elusive. The present study demonstrated that levels of cartilage degradation, H2BK120ub1, and its regulator WW domain-containing adapter protein with coiled-coil (WAC) were increased in cartilage in human rheumatoid arthritis (RA) and osteoarthritis (OA) patients as well as in experimental RA and OA mice. By regulating H2BK120ub1 and H3K27me3, WAC regulated the secretion of inflammatory and cartilage-degrading factors. WAC influenced the level of H3K27me3 by regulating nuclear entry of the H3K27 demethylase KDM6B, and acted as a key factor of the crosstalk between H2BK120ub1 and H3K27me3. The cartilage-specific knockout of WAC demonstrated the ability to alleviate cartilage degradation in collagen-induced arthritis (CIA) and collagenase-induced osteoarthritis (CIOA) mice. Through molecular docking and dynamic simulation, doxercalciferol was found to inhibit WAC and the development of cartilage degradation in the CIA and CIOA models. Our study demonstrated that WAC is a key factor of cartilage degradation in arthritis, and targeting WAC by doxercalciferol could be a viable therapeutic strategy for treating cartilage destruction in several types of arthritis.

Functional dyspepsia (FD), characterized by persistent or recurrent dyspeptic symptoms without identifiable organic, systemic or metabolic causes, is an increasingly recognized global health issue. The objective of this guideline is to equip clinicians and nursing professionals with evidence-based strategies for the management and treatment of adult patients with FD using traditional Chinese medicine (TCM). The Guideline Development Group consulted existing TCM consensus documents on FD and convened a panel of 35 clinicians to generate initial clinical queries. To address these queries, a systematic literature search was conducted across PubMed, EMBASE, the Cochrane Library, China National Knowledge Infrastructure (CNKI), VIP Database, China Biology Medicine (SinoMed) Database, Wanfang Database, Traditional Medicine Research Data Expanded (TMRDE), and the Traditional Chinese Medical Literature Analysis and Retrieval System (TCMLARS). The evidence from the literature was critically appraised using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. The strength of the recommendations was ascertained through a consensus-building process involving TCM and allopathic medicine experts, methodologists, pharmacologists, nursing specialists, and health economists, leveraging their collective expertise and empirical knowledge. The guideline comprises a total of 43 evidence-informed recommendations that span a range of clinical aspects, including the pathogenesis according to TCM, diagnostic approaches, therapeutic interventions, efficacy assessments, and prognostic considerations.

Objective:To investigate molecular mechanisms underlying the inflammatory response induced by Cutibacterium acnes ( C. acnes) biofilms in human primary keratinocytes. Methods:A C. acnes biofilm model was established in vitro, and confocal fluorescence microscopy was performed to examine its three-dimensional structure. The cultured human primary keratinocytes were divided into 3 groups: a dimethyl sulfoxide (DMSO) control group (treated with 0.01% DMSO alone), a C. acnes suspension group (co-incubated with C. acnes suspensions), and a C. acnes biofilm group (co-incubated with C. acnes biofilms). Real-time fluorescence-based quantitative PCR (RT-qPCR) was performed to determine the relative mRNA expression of interleukin (IL) -6, IL-8, and tumor necrosis factor (TNF) -α in the groups after 6-hour culture, enzyme-linked immunosorbent assay to detect the free protein levels of IL-6, IL-8, and TNF-α in the groups after 24-hour culture, and Western blot analysis to determine the protein expression of Toll-like receptor 2 (TLR2) in keratinocytes. In addition, some human primary keratinocytes were pretreated with key molecular blockers targeting the TLR2/mitogen-activated protein kinase (MAPK) /nuclear factor (NF) -κB signaling pathway (C29, ST2825, BAY11-7082, SB203580, U0126-EtOH), and then co-incubated with C. acnes biofilms; the DMSO control group and the C. acnes biofilm group receiving no pretreatment were simultaneously set as negative and positive controls, respectively. The mRNA and free protein expression levels of IL-6, IL-8, and TNF-α were then detected in the above groups. One-way analysis of variance was used for comparisons among multiple groups, and the Bonferroni method was used for multiple comparisons. Results:Confocal fluorescence microscopy demonstrated a three-dimensional C. acnes biofilm structure resembling a lawn, and the biofilm grew well. RT-qPCR and ELISA showed significant differences in the mRNA and free protein expression levels of IL-6, IL-8, and TNF-α among the C. acnes biofilm group, C. acnes suspension group and DMSO control group (mRNA: F = 89.70, 312.17, 46.09, respectively, all P < 0.001; free protein: F = 886.12, 634.25, 307.01, respectively, all P < 0.001) ; in detail, the mRNA and free protein expression levels of IL-6, IL-8, and TNF-α were significantly higher in the C. acnes biofilm group than in the C. acnes suspension group and DMSO control group (all P < 0.001) ; the C. acnes suspension group showed significantly increased expression levels of IL-6 mRNA and TNF-α free protein compared with the DMSO control group ( P < 0.001, = 0.003, respectively), while there were no significant differences in the expression of IL-6 free protein, TNF-α mRNA, or IL-8 mRNA and free protein between the 2 groups (all P > 0.05). Western blot analysis showed that the TLR2 protein expression was significantly higher in the C. acnes suspension group and C. acnes biofilm group than in the DMSO control group. After the pretreatment with molecular blockers targeting the MAPK/NF-κB signaling pathway and co-incubation with C. acnes biofilms, the mRNA and free protein expression levels of IL-6, IL-8 and TNF-α were all significantly lower in the C29 group, ST2825 group, BAY11-7082 group, SB203580 group, U0126-EtOH group, as well as in the DMSO control group compared with the C. acnes biofilm group (all P < 0.05) . Conclusion:The C. acnes biofilms exhibited a strong ability to induce inflammatory responses in human keratinocytes, possibly through the activation of the TLR2/MAPK/NF-κB signaling pathway.

Background/Aims: Nonalcoholic fatty liver disease (NAFLD) is closely associated with diabetes. The cumulative impact of both diseases synergistically increases risk of adverse events. However, present population analysis is predominantly conducted with reference to non-NAFLD individuals and has not yet examined the impact of prediabetes. Hence, we sought to conduct a retrospective analysis on the impact of diabetic status in NAFLD patients, referencing non-diabetic NAFLD individuals. Methods: Data from the National Health and Nutrition Examination Survey 1999–2018 was used. Hepatic steatosis was defined with United States Fatty Liver Index (US-FLI) and FLI at a cut-off of 30 and 60 respectively, in absence of substantial alcohol use. A multivariate generalized linear model was used for risk ratios of binary outcomes while survival analysis was conducted with Cox regression and Fine Gray model for competing risk. Results: Of 32,234 patients, 28.92% were identified to have NAFLD. 36.04%, 38.32% and 25.63% were non-diabetic, prediabetic and diabetic respectively. Diabetic NAFLD significantly increased risk of cardiovascular disease (CVD), stroke, chronic kidney disease, all-cause and CVD mortality compared to non-diabetic NAFLD. However, prediabetic NAFLD only significantly increased the risk of CVD and did not result in a higher risk of mortality. Conclusions Given the increased risk of adverse outcomes, this study highlights the importance of regular diabetes screening in NAFLD and adoption of prompt lifestyle modifications to reduce disease progression. Facing high cardiovascular burden, prediabetic and diabetic NAFLD individuals can benefit from early cardiovascular referrals to reduce risk of CVD events and mortality.

Objective:To study the efficacy and mechanism of Shugan Jianpi Jiedu prescription （SJJ） in the treatment of triple-negative breast cancer through in vitro cell experiments. Method:The following groups were set up in this study： a normal serum group，a pirarubicin group，and low-，medium-， and high-dose SJJ-medicated serum groups. Twenty SD rats were randomly divided into four groups and administered with SJJ solution （16.8，8.2，4.05 g·kg^-1） and normal saline （equal volume） according to the body surface area to prepare serum. MDA-MB-231 cells were treated separately. The proliferation， migration and invasion of MDA-MB-231 cells were detected by the cell counting kit-8（CCK-8），wound healing assay and transwell cell invasion assay. The phosphoinositide 3-kinase （PI3K），protein kinase B （Akt）， and mechanistic target of rapamycin （mTOR） protein expression levels in MDA-MB-231 cells were tested by the Western blot. Result:The cell proliferation in the three different doses of medicated serum groups and the pirarubicin positive control group was significantly inhibited as compared with that in the normal serum group（P<0.01），and there was no statistical difference for this between the medium/high dose medicated serum group and the pirarubicin positive control group.The wound healing in the SJJ-medicated serum groups and the pirarubicin group was slowed down as compared with that in the normal serum group （P<0.01），and the effect in the SJJ-medicated serum groups was weaker than that in the pirarubicin group （P<0.05，P<0.01）. The number of cells invading the lower transwell chamber was decreased as compared with that in the normal serum group （P<0.01），and there was no statistical difference between the medium-/high-dose SJJ-medicated serum groups and the pirarubicin group. Western blot results showed that 48 h after treatment，the PI3K，Akt， and mTOR expression levels in the cells of SJJ-medicated serum groups and the pirarubicin group were lower than those of the normal serum group（P<0.01）. Conclusion:The SJJ-medicated serum could inhibit the proliferation， migration and invasion of MDA-MB-231 cells presumedly by down-regulating the protein expression levels in the PI3K/Akt/mTOR signaling pathway.
