Epigenetic pathways play a critical role in the initiation, progression, and metastasis of cancer. Over the past few decades, significant progress has been made in the development of targeted epigenetic modulators (e.g., inhibitors). However, epigenetic inhibitors have faced multiple challenges, including limited clinical efficacy, toxicities, lack of subtype selectivity, and drug resistance. As a result, the design of new epigenetic modulators (e.g., degraders) such as PROTACs, molecular glue, and hydrophobic tagging (HyT) degraders has garnered significant attention from both academia and pharmaceutical industry, and numerous epigenetic degraders have been discovered in the past decade. In this review, we aim to provide an in-depth illustration of new degrading strategies (2017-2023) targeting epigenetic proteins for cancer therapy, focusing on the rational design, pharmacodynamics, pharmacokinetics, clinical status, and crystal structure information of these degraders. Importantly, we also provide deep insights into the potential challenges and corresponding remedies of this approach to drug design and development. Overall, we hope this review will offer a better mechanistic understanding and serve as a useful guide for the development of emerging epigenetic-targeting degraders.

OBJECTIVE To determine the optimal therapeutic plan for metastatic hormone-sensitive prostate cancer (mHSPC), and to provide reference for clinical decision-making. METHODS Retrieved from Medline, Embase, BIOSIS preview, the Cochrane Library and ClinicalTrials. gov systematically, randomized controlled trials about mHSPC therapy, with overall survival (OS) and radiographic progression-free survival (rPFS) as efficacy outcomes and the incidence of serious adverse events (SAEs) as safety outcome, were collected during the inception-Mar. 2022. Two researchers independently screened the literature, extracted data, and evaluated the risk of bias for the included study before conducting a Bayesian network meta-analysis. RESULTS Eight studies with 9 437 patients were finally included. The effectiveness and safety of 7 therapy plans were compared [abiraterone acetate, apalutamide, darolutamide+docetaxel, docetaxel, enzalutamide, standard non-steroidal antiandrogen (SNA) in addition to ADT, and ADT alone]. In terms of efficacy index, the most beneficial regimen (except for ADT+SNA) for OS was ADT+darolutamide+docetaxel (HR=0.54, 95%CI of 0.44-0.66), followed by ADT+abiraterone acetate (HR=0.64,95%CI of 0.57- 0.71), apalutamide (HR=0.65, 95%CI of 0.53-0.79), enzalutamide (HR=0.66, 95%CI of 0.53-0.82); the least beneficial regimen for OS was ADT+docetaxel (HR=0.79, 95%CI of 0.71-0.88). The most beneficial regimen (except for ADT+SNA) for rPFS was ADT+enzalutamide (HR=0.39, 95%CI of 0.30-0.50), followed by ADT+apalutamide (HR=0.48, 95%CI of 0.39- 0.60), abiraterone acetate (HR=0.57, 95%CI of 0.51-0.64), docetaxel (HR=0.62, 95%CI of 0.56-0.69). The results of the tumor- loading subgroup analysis were the same. In terms of safety, ADT+darolutamide+docetaxel (OR=25.86, 95%CI of 14.08-51.33), and ADT+docetaxel (OR=23.35, 95%CI of 13.26-44.81) were associated with markedly increased SAEs; the incidence of SAEs caused by ADT+abiraterone acetate (OR=1.42,95%CI of 1.10-1.82) was slightly increased, and those of other therapy plans had no significant difference. CONCLUSIONS Compared with ADT alone, ADT+ darolutamide+docetaxel may provide the most significant OS benefit, but the incidence of SAEs is increased greatly; compared with ADT+docetaxel, ADT+abiraterone acetate, apalutamide or enzalutamide provide more OS benefits. ADT+enzalutamide provide optimal rPFS benefits with no increased SAEs.

OBJECTIVE To establish high performance liquid chromatography (HPLC) fingerprint of Xiaohe syrup and determine the contents of 10 effective ingredients in them. METHODS With 12 batches of Xiaohe syrup as samples, ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was adopted with Athena C18 (250 mm×4.6 mm, 5 μm) as the chromatographic column, acetonitrile-0.1% phosphoric acid aqueous solution as mobile phase for gradient elution. The flow rate was 1.0 mL/min, and the detection wavelength was 210 nm. Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprint (2012A version) was imported to establish the fingerprint of Xiaohe syrup and evaluate the similarity. The content determination was performed on ACQUITY UPLC BEH C18( 100 mm×2.1 mm, 1.7 μm) chromatographic column, with 0.01% formic acid acetonitrile-0.01% formic acid water as mobile phase for gradient elution at a flow rate of 0.4 mL/min; combined with high-resolution mass spectrometer, positive and negative ions were scanned with an electric spray ion source to determine the content of each main component in 12 batches of Xiaohe syrup. RESULTS A total of 33 common peaks were calibrated in 12 batches of samples, with similarities greater than 0.97; 10 chromatographic peaks were confirmed, namely flavonoid glycosides, paeoniflorin, ferulic acid, naringin, rosmarinic acid, neohesperidin, salvianolic acid B, tetrahydropalmatine, saikosaponin A, and saikosaponin D. The results of content determination showed that the above 10 components had good linear relationships within their respective mass concentration ranges (all R 2>0.999), with contents ranging from 0.35 to 0.64, 3.15 to 5.61, 0.11 to 0.17, 1.68 to 3.17, 1.59 to 1.90, 1.15 to 1.64, 0.78 to 1.48, 0.11 to 0.26, 0.06 to 0.13, and 0.33 to 0.61 mg/mL, respectively. CONCLUSIONS The main components of 12 batches of Xiaohe syrup are similar, but the contents vary; HPLC fingerprint and UPLC-MS/MS content determination method established in this study can be used for comprehensive quality evaluation of Xiaohe syrup.

Objective:
To evaluate the preventive effect of implementing the free influenza vaccination policy on school absence among primary and secondary school students, so as to provide a reference for formulating and adjusting vaccination strategies.
Methods:
Among primary and secondary school students aged 6 to 18 in Longgang District, Shenzhen, they were divided into a vaccinated group (265 996 students) and an unvaccinated group (122 513 students) according to their influenza vaccination history during November 2023. Propensity score matching was used to conduct a 1∶1 match between the two groups to balance covariates. The number of absences per month was set as the dependent variable to construct a difference in differences model, and Poisson regression was employed to analyze the overall and multi time point effects.
Results:
Vaccination against influenza was associated with low rate of absenteeism among primary and secondary school students, with an overall preventive effect of 26.52% (95% CI = 23.47% -29.45%). The preventive effects in November (the month of vaccination) and December 2023, January and March 2024 were 42.12%, 40.12%, 30.33% and 20.91%, respectively. The preventive effect of the influenza vaccine on absenteeism among primary school students (26.39%) was not significantly different from that among secondary school students ( 27.97% ) ( P >0.05). The regression coefficient for class vaccination rates ranged from 0.998 to 0.999 ( P <0.01), indicating that for every 10% increase in influenza vaccination rates, absenteeism could be reduced by 1.5% to 2.2%.
Conclusion
Implementing free influenza vaccination for primary and secondary school students might help to reduce the risk of absenteeism, yielding significant socioeconomic benefits.

Recent studies on male infertility reveal a growing worry: more infertile men are dealing with inflammation in the testis. Analyzing testicular biopsies from infertile men highlights a significant presence of inflammation. This connection, supported by clinical and pathological evidence, emphasizes that testicular inflammation hampers sperm production, leading to lasting declines in sperm count and quality. However, the exact reasons behind male infertility due to orchitis, a type of testicular inflammation, are still uncertain. Understanding these fundamental aspects of molecular signals and cellular mechanisms in testicular inflammation is crucial. Our review delves into recent literature with a dual objective: elucidating potential mechanisms involving immune cells, non-immune cells, and cytokines that link orchitis to male infertility, while also paving the way for precise interventions and solutions to address the challenges of male infertility.
