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 effects of long-term X-ray radiation exposure on the tumor risk of medical X-ray workers in Jiangsu province, and to provide a scientific basis for the development of occupational protection policies and the improvement of workers′ health.Methods:By using a combination of retrospective and prospective cohort research method, the medical diagnostic X-ray workers who worked in the radiology department of all hospitals in Jiangsu province between 1950 and 1980 were selected as the radiology group.In the meantime medical personnel in internal medicine, otorhinolaryngology, pediatrics and other medical departments who had not been engaged in radiology during the same period of time at the same hospital were selected as the control group to form a survey cohort. The cumulative number of person-years of observation of the cohort during 1950-2011 was calculated, and the relative risk of various malignant tumors among medical X-ray workers was calculated by using Cox regression model after adjusting for sex, attained age, year of birth, and year of work initiation.Results:A total of 6 954 follow-ups was completed for the cohort, including 3 649 in the irradiation group and 3 305 in the control group, totally 340 483 person-years of observation. As of December 31, 2021, there were 1 328 patients with malignant tumors in this cohort. Cox regression result showed that compared with the control group, the irradiation group who had developed lung cancer ( RR=1.60, 95% CI 1.24-2.08), lymphoma ( RR =4.28, 95% CI 1.54-11.93), solid cancer ( RR =1.17, 95% CI 1.04-1.31), and total cancer ( RR =1.29, 95% CI 1.14-1.46) had significantly higher relative risks ( Z=3.56, 2.78, 2.71, 3.96, P<0.05). Stratified analyses showed that the risks of lung, lymphoma, solid and total cancers were higher in the radiation group than in the control group for males and for those who arrived at the age of 61 years or older ( χ2=6.70-33.86, P<0.05). The risks of lung, solid and total cancers were higher in the radiation group than in the control group for those who started to work in the age group of 21 to 25 years ( χ2=6.46, 6.16, 5.62, P<0.05). Conclusions:The relative risks of lung, lymphoma, solid and total cancers among medical X-ray workers in Jiangsu province are significantly higher, suggesting that attention should be paid to strengthening radiation protection for radiation workers in their radiological practices.
