Objective To observe the clinical effect of Jiu-Wei-Yong-An granule combined with cetirizine in the treatment of damp-heat accumulation syndrome of eczema. Methods 108 eczema patients with syndrome of damp-heat accumulated in the skin, treated in the Department of Traditional Chinese Surgery in the First Affiliated Hospital of Naval Medical University from December 2021 to March 2023, were selected. They were randomly divided into an observation group and a control group, 54 cases in each. Both groups took cetirizine tablets orally for basic treatment. The observation group was given Jiu-Wei-Yong-An granules, and the control group was given placebos of the same. The clinical efficacy before and after treatment in the two groups was observed and compared, including TCM syndrome scores, eczema area and severity index (EASI), visual analogue scale (VAS), and adverse reactions. Results After treatment, the total effective rate of the observation group (88.9%) was higher than that of the control group (77.8%), and the difference was statistically significant (P<0.05). After treatment, the TCM syndrome score, EASI and VAS in the observation group were significantly lower than those in the control group (P<0.05), and the difference was statistically significant. There was no significant difference in the total rate of adverse reactions between the two groups (P>0.05). Conclusion The combination of Jiu-Wei-Yong-An granules and cetirizine tablets in the treatment of damp-heat eczema showed significantly better clinical outcomes in the observation group compared to the control. It effectively improved patient conditions, reduced skin lesion areas, and alleviated itching, with both safety and efficacy that merit clinical promotion.

Objective To evaluate the clinical efficacy of Traditional Chinese Medicine (TCM)external treatment methods in alleviating skin pruritus caused by eczema through a Meta-analysis. Methods Randomized clinical trials investigating the use of TCM external treatment methods for skin pruritus caused by eczema were searched in databases including China National Knowledge Infrastructure (CNKI), VIP, Wanfang, Sinomed, PubMed, Embase, LILACS, and Cochrane, up to December 2024. Two reviewers independently screened and entered the statistical data, conducted bias risk assessment by the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.0, and performed Meta-analysis using RevMan 5.4.1. Results Ultimately, 14 studies involving 1 788 patients were included. Compared to the control group, TCM external treatment methods (treatment group)showed better improvement in pruritus scores (Z=11.88, P<0.000 01), better improvement in Eczema Area and Severity Index (EASI) scores (Z=23.15, P<0.000 01), higher overall clinical efficacy rate (Z=6.21, P<0.000 01), better improvement in TCM symptoms (Z=5.49, P<0.000 01), and lower clinical recurrence rate (Z=2.88, P=0.004). Three of the included studies mentioned adverse reactions, with the treatment group showing lower adverse reactions than the control group. Conclusion The external treatment of TCM was more effective in treating skin pruritus caused by eczema compared to the control group. Given the biases and heterogeneity in the included literature, this conclusion needs to be further substantiated by more large-scale, multi-center, randomized, controlled, and double-blind studies.

The regulatory processes in developmental biology research are significantly influenced by long non-coding RNAs (lncRNAs). However, the dynamics of lncRNA expression during human tooth development remain poorly understood. In this research, we examined the lncRNAs present in the dental epithelium (DE) and dental mesenchyme (DM) at the late bud, cap, and early bell stages of human fetal tooth development through bulk RNA sequencing. Developmental regulators co-expressed with neighboring lncRNAs were significantly enriched in odontogenesis. Specific lncRNAs expressed in the DE and DM, such as PANCR, MIR205HG, DLX6-AS1, and DNM3OS, were identified through a combination of bulk RNA sequencing and single-cell analysis. Further subcluster analysis revealed lncRNAs specifically expressed in important regions of the tooth germ, such as the inner enamel epithelium and coronal dental papilla (CDP). Functionally, we demonstrated that CDP-specific DLX6-AS1 enhanced odontoblastic differentiation in human tooth germ mesenchymal cells and dental pulp stem cells. These findings suggest that lncRNAs could serve as valuable cell markers for tooth development and potential therapeutic targets for tooth regeneration.

Proteolysis-targeting chimeras (PROTACs) have shown considerable therapeutic potential across diverse fields such as cancer, inflammation, and neurodegenerative diseases, with numerous candidates already progressing into clinical trials. More recently, their application in antiviral therapy has been rapidly gaining momentum. This review systematically outlines the mechanistic foundations and design principles of PROTACs, highlights recent advances targeting coronaviruses (including SARS-CoV-2), hepatitis C virus, human immunodeficiency virus, and influenza viruses, and critically assesses key challenges—particularly the limited diversity of E3 ligase ligands, suboptimal oral bioavailability, and the lack of integrated platforms for druggability evaluation. Looking ahead, innovations in ligand discovery, pathway modulation, delivery technologies, and conditionally activated PROTAC designs are anticipated to overcome these barriers, ushering in a new era of precise and effective antiviral therapeutics.

OBJECTIVE
To investigate the effect of Banxia Xiexin decoction(BXD) on colitis associated cancer(CAC) mice and its related mechanism.
METHODS
Seventy-five C57BL/6 mice were randomly divided into normal group, model group, Banxia Xiexin decoction low-dose group, high-dose group and mesalazine group. Except for the normal group, the mice in the other groups were intraperitoneally injected with azoxymethane combined with oral dextran sodium sulfate to establish the CAC model. BXD and mesalazine were given respectively for intervention. The general conditions of all mice were observed and recorded, and the changes of body weight, disease activity index, colon length and tumor number were monitored. HE staining was utilized to observe the pathological changes of colon tissue. The expression levels of PCNA, NF-κB P65 and IκB-α were detected by immunohistochemistry. The mRNA levels of IL-17A, N-cadherin, E-cadherin and Bcl-2 were detected by qRT-PCR. Macrophage infiltration was measured using immunostaining analysis. Western blotting was applied to analyze the expression of NF-κB, E-cadherin and N-cadherin proteins in colon tissues of each group.
RESULTS
There was no significant tumor occurrence in the normal group, while the body weight of the model group mice was significantly reduced and the number of colon tumors increased. The colon length, number of tumors, and degree of inflammatory cell infiltration in the BXD group were significantly improved compared to the model group. Immunohistochemical results showed that the expression of PCNA, NF-κB P65 and IκB-α protein in colon tissue of model group was remarkably increased (P<0.01). Immunofluorescence results showed that the number of F4/80, CD80 and CD206 positive macrophages in the colon tissue of the model group increased (P<0.05 or P<0.01). The results of RT-PCR demonstrated that the levels of IL-17A, N-cadherin and Bcl-2 mRNA in the colon tissue of the model group were significantly increased (P<0.01), while the level of E-cadherin mRNA was fundamentally decreased (P<0.01). Western blotting results displayed that the expression levels of NF-κB and N-cadherin protein in colon tissue of model group were up-regulated (P<0.01), while E-cadherin was significantly down-regulated (P<0.01). Compared with the model group, the changes of the above indexes in the BXD and mesalazine groups were ameliorated, with statistical differences (P<0.05 or P<0.01), and the changes in the BXD high-dose group were more significant.
CONCLUSION
BXD exhibits strong anti-inflammatory and anti-tumor benefits in CAC mice, inhibiting macrophage activation in colon tissue and promoting M2 polarization, while reducing the expression of tumor associated proteins PCNA and Bcl-2, and block the progression of EMT related proteins (E-cadherin and N-cadherin). The mechanism may connect to suppressing NF-κB P65 and IκB-α activation to regulate the NF-κB signaling pathway.
