Repeat expansion diseases(REDs) are a group of genetic disorders caused by the pathological expansion of specific short tandem repeats(STRs) in genomic DNA. They are characterized by significant clinical and genetic heterogeneity. Owing to the complexity of their pathogenesis, effective treatments remain elusive. With the in-depth analysis of the pathogenesis of these diseases, along with the development and innovation of targeting tools in recent years, targeted therapy strategies have become a research hotspot, and some antisense oligonucleotide drugs have entered the clinical trial stage. This article aims to review the latest advances in basic research and clinical trial outcomes of targeted therapy at the DNA, RNA and protein levels. Currently, this field still faces key bottlenecks including a high risk of off-target effects, low delivery efficiency, and challenges in clinical translation. Future efforts should focus on the optimization and refinement of targeting tools and delivery vectors, as well as multilevel collaborative combination therapeutic strategies.Combined with precise clinical classification and staging, this will promote the fundamental transformation of REDs treatment from symptomatic supportive care to etiological intervention.

ObjectiveTo observe the effect of modified Huanglian Wendantang on oxidative stress in metabolic syndrome. MethodsA total of 180 patients with metabolic syndrome treated in the outpatient clinics and wards of the First Affiliated Hospital of Heilongjiang University of Traditional Chinese Medicine from October 2023 to May 2025 were enrolled in this study. According to the randomized numerical table method， the patients were assigned into two groups （90 cases）. The basic treatment of the two groups was the same， and the observation group was additionally treated with modified Huanglian Wendantang. The course of treatment was 3 months. The two groups were compared in terms of traditional Chinese medicine （TCM） efficacy， obesity degree ［waist circumference （WC）， body mass index （BMI）， waist-to-hip ratio （WHR）， waist-to-height ratio （WHtR）］， blood pressure indicators ［systolic blood pressure （SBP） and diastolic blood pressure （DBP）］， lipids and glucose indicators ［total cholesterol （TC）， triglycerides （TG）， high-density lipoprotein cholesterol （HDL-C）， low-density lipoprotein cholesterol （LDL-C）， fasting insulin （FINS）， fasting glucose （FPG）， 2-hour postprandial glucose （2 h PG）， and glycosylated hemoglobin （HbA1c）］， insulin resistance indicators ［homeostatic model assessment for insulin resistance （HOMA-IR）， triglyceride-glucose index （TYG index）， triacylglycerol-to-high-density lipoprotein cholesterol （TG/HDL） ratio］， oxidative stress indicators ［malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione （GSH）， glutathione peroxidase （GSH-Px）， catalase （CAT）， and reactive oxygen species （ROS）］， and the safety of treatment. ResultsIn terms of TCM efficacy， the treatment in the observation group was significantly effective in 46 cases， effective in 30 cases， and ineffective in 10 cases， with the total effective rate of 88.4%. The treatment in the control group was significantly effective in 33 cases， effective in 28 cases， and ineffective in 23 cases， with the total effective rate of 72.6%. The observation group had higher total effective rate than the control group （χ²=11.26，P<0.05）. After treatment， both groups showed declined levels of WC， BMI， WHR， WHtR， SBP， DBP， TC， TG， LDL-C， FPG， FINS， 2 h PG， HbA1c， HOMA-IR， TG/HDL ratio， TYG index， MDA， and ROS and elevated levels of HDL-C， SOD， GSH， GSH-Px， and CAT （P<0.05）. After treatment， the observation group showed lower levels of WC， BMI， WHR， WHtR， TC， TG， LDL-C， FPG， FINS， 2 h PG， HbA1c， HOMA-IR， TG/HDL ratio， TYG index， MDA， and ROS and higher levels of HDL-C， SOD， GSH， GSH-Px， and CAT than the control group （P<0.05）. However， after treatment， there was no significant difference in SBP or DBP between the observation group and the control group. No significant adverse reactions were observed in either group. ConclusionModified Huanglian Wendantang can significantly alleviate metabolic syndrome symptoms and reduce oxidative stress， exhibiting antioxidant effects. Moreover， it does not induce adverse reactions， demonstrating safety.

ObjectiveTo observe the clinical effect of modified Huanglian Wendantang on cardiovascular risk factors in patients with metabolic syndrome under the guidance of treating disease before its onset. MethodsA total of 82 patients with metabolic syndrome treated in the First Affiliated Hospital of Heilongjiang University of Chinese Medicine from July 2023 to July 2024 were selected and allocated into an observation group （41 cases） and a control group （41 cases） by the random number table method. The control group received routine treatment， and the observation group was treated with modified Huanglian Wendantang on the basis of routine treatment. Both groups were treated for 8 weeks. The therapeutic effects on TCM symptoms after treatment in the two groups were evaluated. The levels of obesity degree indicators， blood pressure indicators， glucose and lipid metabolism indicators， inflammatory factors， and vascular endothelial function indicators before and after treatment in the two groups were measured， and the treatment safety was evaluated. ResultsAfter treatment， the total response rate of TCM symptoms in the observation group was 97.56% （40/41）， which was higher than that （87.80%， 36/41） in the control group （χ²=5.205， P<0.05）. After treatment， both groups showed declines （P<0.05） in systolic blood pressure （SBD）， diastolic blood pressure （DBP）， triglyceride （TG）， total cholesterol （TC）， low density lipoprotein cholesterol （LDL-C）， fasting blood glucose， 2-hour postprandial blood glucose （2 h PG）， glycosylated hemoglobin （HbA1c）， fasting insulin （FINS）， Homeostatic Model Assessment for Insulin Resistance （HOMA-IR）， body mass index （BMI）， waist circumference （WC）， waist-to-hip ratio （WHR）， leptin （LEP）， interleukin-6 （IL-6）， tumor necrosis factor-α （TNF-α）， endothelin-1 （ET-1）， and inducible nitric oxide synthase （iNOS）. Moreover， the declines in the observation group were more obvious than those in the control group （P<0.05， P<0.01）. After treatment， both groups showed elevated levels of high density lipoprotein cholesterol （HDL-C）， adiponectin （ADP）， nitric oxide （NO）， and endothelial nitric oxide synthase （eNOS） （P<0.05）， and the above indexes in the observation group were higher than those in the control group （P<0.01）. ConclusionUnder the guidance of the thought of treating disease before its onset， modified Huanglian Wendantang was used to treat patients with metabolic syndrome. The decoction improved the clinical efficacy by ameliorating IR to improve insulin sensitivity， reducing inflammation， and protecting the vascular endothelial function. It inhibits cardiovascular risk factors without inducing adverse reactions， being worthy of clinical application and promotion.

This article reports a novel clinical approach for root canal treatment in a case of periapical periodontitis. The patient presented with a buccal wedge-shaped defect exposing the pulp and persistent sinus tract drainage in the mandibular premolar. Radiographic and cone-beam computed tomography (CBCT) evaluation revealed complex root canal anatomy, rendering conventional root canal therapy ineffective for managing the lingual canal. The Department of Stomatology, Peking Union Medical College Hospital (PUMCH) developed an innovative minimally invasive technique—Photoacoustic-steaming United Minimal-invasive Chemomechanical-prepara-tion Hydramatic-obturation(PUMCH) Therapy, which successfully addressed this clinical challenge. This technique employs enhanced chemical disinfection to partially replace mechanical debridement and utilizes negative pressure-guided hydraulic obturation with bioceramic materials. At the 1-month follow-up, complete sinus tract healing and significant symptomatic improvement were observed. This represents the first reported application of PUMCH Therapy in complex root canal anatomy, demonstrating its minimally invasive nature, high efficiency, and precision advantages in endodontic treatment, thereby providing new insights for endodontic therapy.

OBJECTIVES: Depression is a common negative emotion that can significantly impact physical and mental health. Due to their occupational characteristics, medical staff are more susceptible to depression compared to the general population. This study aims to explore the influence of future-oriented coping on depression among medical staff and the mediating roles of psychological resilience and perceived stress, providing theoretical guidance for depression intervention strategies in this group. METHODS: A cross-sectional survey was conducted among medical staff at a tertiary hospital using convenience sampling. Data were collected via the "Wenjuanxing" platform. A total of 754 questionnaires were distributed; after excluding invalid responses (e.g., duplicate IPs or insufficient completion time), 655 valid questionnaires were retained (valid response rate: 86.87%). Instruments included a demographic questionnaire, the Future-Oriented Coping Scale, the Connor-Davidson Resilience Scale, the Perceived Stress Scale, and the Self-Rating Depression Scale. All scales demonstrated high internal consistency (Cronbach's α>0.88) and validity. SPSS 27.0 was used for descriptive analysis, and PROCESS macro (Model 6) was used to test the chain mediation model. Harman's one-factor test was applied to control for common method bias. RESULTS: Descriptive analyses showed that future-oriented coping was positively correlated with psychological resilience and negatively correlated with perceived stress and depression. Mediation analysis revealed that future-oriented coping significantly predicted lower depression levels among medical staff (β=-0.283, P<0.001). Psychological resilience partially mediated the relationship (effect size=-0.329, accounting for 34.13% of the total effect), as did perceived stress (effect size=-0.099, 10.27%). A significant chain mediation path was identified: "future-oriented coping → psychological resilience → perceived stress → depression" (effect size=-0.253, 26.24%). The total indirect effect accounted for 70.64% of the overall effect, highlighting the substantial role of the mediating pathways. CONCLUSIONS Future-oriented coping can reduce depressive symptoms in medical staff, with psychological resilience and perceived stress serving as key mediators in a chain structure. These findings suggest that enhancing future-oriented coping strategies and psychological resilience may improve stress adaptation and reduce depression levels in this population.

BACKGROUND: Chronic liver disease (CLD), mainly non-alcoholic fatty liver disease (NAFLD), is a significant public health concern worldwide. This study aims to quantify the burden of NAFLD in CLD globally and within China, using data from the Global Burden of Disease (GBD) Study 2021, providing crucial insights for global and local health policies. METHODS: The study used comprehensive data from the GBD study 2021. It included estimates of prevalence, incidence, mortality, and disability-adjusted life years (DALYs). Age-standardized rates and average annual percent change (AAPC) from 2011 to 2021 were reported. A meticulous decomposition analysis was conducted. RESULTS: In 2021, there were 1582.5 million prevalent cases, 47.6 million incident cases, 1.4 million deaths, and 44.4 million DALYs attributable to CLD, globally. Among these, NAFLD has emerged as the predominant cause, accounting for 78.0% of all prevalent CLD cases (1234.7 million) and 87.2% of incident cases (41.5 million). Correspondingly, NAFLD had the highest age-standardized prevalence (15,017.5 per 100,000 population) and incidence (876.5 per 100,000 population) rates among CLDs. In addition, China's CLD age-standardized prevalence rate was 21,659.5 per 100,000 population, and the age-standardized incidence rate was 752.6 per 100,000 population, higher than the global average. From 2011 to 2021, the global prevalence rate of CLD increased slowly (AAPC = 0.17), consistent with the trend in China (AAPC = 0.23). Furthermore, the prevalence rate of NAFLD rose significantly in China (AAPC = 1.30) compared with the global average (AAPC = 0.91). Decomposition analysis also showed the worldwide increase in deaths and DALYs for NAFLD, which were primarily attributable to population growth and aging. CONCLUSIONS The burden of CLD and NAFLD remains substantial globally and within China in terms of high prevalence and incidence. As such, this underscores the need for targeted prevention and treatment strategies. These findings emphasize the importance of continued surveillance and research to mitigate the growing impact of liver diseases on global and Chinese health systems.

Poly(ADP-ribosyl)ation (PARylation) is a specific form of post-translational modification (PTM) predominantly triggered by the activation of poly-ADP-ribose polymerase 1 (PARP1). However, the role and mechanism of PARylation in the advancement of acute kidney injury (AKI) remain undetermined. Here, we demonstrated the significant upregulation of PARP1 and its associated PARylation in murine models of AKI, consistent with renal biopsy findings in patients with AKI. This elevation in PARP1 expression might be attributed to trimethylation of histone H3 lysine 4 (H3K4me3). Furthermore, a reduction in PARylation levels mitigated renal dysfunction in the AKI mouse models. Mechanistically, liquid chromatography-mass spectrometry indicated that PARylation mainly occurred in receptor for activated C kinase 1 (RACK1), thereby facilitating its subsequent phosphorylation. Moreover, the phosphorylation of RACK1 enhanced its dimerization and accelerated the ubiquitination-mediated hypoxia inducible factor-1α (HIF-1α) degradation, thereby exacerbating kidney injury. Additionally, we identified a PARP1 proteolysis-targeting chimera (PROTAC), A19, as a PARP1 degrader that demonstrated superior protective effects against renal injury compared with PJ34, a previously identified PARP1 inhibitor. Collectively, both genetic and drug-based inhibition of PARylation mitigated kidney injury, indicating that the PARylated RACK1/HIF-1α axis could be a promising therapeutic target for AKI treatment.
