In China, the number of chronic pain patients has exceeded 300 million, making chronic pain the third major health problem after tumors and cardiovascular diseases. Particularly concerning is the gradual emergence of hypertension and chronic low back pain as public health problems that threaten public health and increase the global economic burden. Modern research shows that the incidence of coexisting hypertension is higher among patients with chronic low back pain. Additionally, evidence indicates that the use of NSAIDs for pain relief can have adverse effects on blood pressure, and some antihypertensive medications may trigger symptoms of low back pain. Thus, addressing chronic pain in hypertensive patients while stabilizing blood pressure is one of the important research questions in the modern treatment of hypertension among middle-aged and elderly individuals. From ancient to modern traditional Chinese medicine(TCM) theory, kidney deficiency has been regarded as the core pathogenesis of low back pain. Recent clinical practices and literature indicate that kidney deficiency plays a crucial role in the modern pathogenesis of hypertension. Both hypertension and chronic low back pain are closely associated with kidney deficiency in TCM theory, revealing a potential mechanism linking the two conditions. Combining the theories of " kidney-essence-marrow" and " nourishing water to moisten wood", a therapeutic strategy centered on tobifying kidney was proposed, including selecting single drugs with kidney-tonifying effects as well as compound formulations and elaborating modern research evidence. The aim is to achieve stable blood pressure control in hypertension patients with chronic low back pain while providing a new treatment perspective for chronic low back pain. This article systematically elaborates on the understanding of hypertension combined with chronic low back pain from both TCM and modern medicine, as well as the therapeutic strategy involving kidney-tonifying drugs, to offer useful references for clinical practice.

Heart failure(HF) is the terminal stage of various cardiovascular diseases, characterized by high morbidity and mortality, and it represents one of the major disease burdens for families and society. In recent years, as research on the molecular mechanisms of HF has deepened, a competing endogenous RNA(ceRNA) network mediated by long non-coding RNAs(lncRNAs) and circular RNAs(circRNAs) has been gradually constructed. Extensive research results have confirmed that the ceRNA network is widely involved in pathological processes such as inflammation, oxidative stress, myocardial hypertrophy, apoptosis, remodeling of extracellular matrix components and structure, and ferroptosis in HF. It reveals the complex pathological mechanisms of HF at the epigenetic level. Traditional Chinese medicine(TCM) plays a unique role in improving symptoms and prognosis of HF and intervenes in the ceRNA network in HF through multi-level and multi-target mechanisms. It improves key pathological processes such as myocardial fibrosis and inflammation, making progress in treating HF at the molecular level. This article summarized recent Chinese and international research on the regulatory mechanisms of ceRNA networks in HF, elaborated on the mechanisms of action of ceRNA networks in different pathological stages of HF, and summarized how effective components and compounds of TCM intervene in the ceRNA network to improve HF, so as to refine the molecular mechanisms of HF and provide directions for more precise molecular targeted therapeutic strategies.

Cardiac fibrosis is characterized by an elevated amount of extracellular matrix (ECM) within the heart. However, the persistence of cardiac fibrosis ultimately diminishes contractility and precipitates cardiac dysfunction. Circular RNAs (circRNAs) are emerging as important regulators of cardiac fibrosis. Here, we elucidate the functional role of a specific circular RNA CELF1 in cardiac fibrosis and delineate a novel feedback loop mechanism. Functionally, circ-CELF1 was involved in enhancing fibrosis-related markers' expression and promoting the proliferation of cardiac fibroblasts (CFs), thereby exacerbating cardiac fibrosis. Mechanistically, circ-CELF1 reduced the ubiquitination-degradation rate of BRPF3, leading to an elevation of BRPF3 protein levels. Additionally, BRPF3 acted as a modular scaffold for the recruitment of histone acetyltransferase KAT7 to facilitate the induction of H3K14 acetylation within the promoters of the Celf1 gene. Thus, the transcription of Celf1 was dramatically activated, thereby inhibiting the subsequent response of their downstream target gene Smad7 expression to promote cardiac fibrosis. Moreover, Celf1 further promoted Celf1 pre-mRNA transcription and back-splicing, thereby establishing a feedback loop for circ-CELF1 production. Consequently, a novel feedback loop involving CELF1/circ-CELF1/BRPF3/KAT7 was established, suggesting that circ-CELF1 may serve as a potential novel therapeutic target for cardiac fibrosis.

OBJECTIVE: To explore the association between acupuncture during controlled ovarian hyperstimulation (COH) and the live birth rate (LBR) using different propensity score methods. METHODS: In this retrospective cohort study, eligible women who underwent a COH were divided into acupuncture and non-acupuncture groups. The primary outcome was LBR, as determined by propensity score matching (PSM). LBR was defined as the delivery of one or more living infants that reached a gestational age over 28 weeks after embryo transfer. The propensity score model encompassed 16 confounding variables. To validate the results, sensitivity analyses were conducted using three additional propensity score methods: propensity score adjustment, inverse probability weighting (IPW), and IPW with a "doubly robust" estimator. RESULTS: The primary cohort encompassed 9751 patients (1830 [18.76%] in the acupuncture group and 7921 [81.23%] in the non-acupuncture group). Following 1:1 PSM, a higher LBR was found in the acupuncture cohort (41.4% [755/1824] vs 36.4% [664/1824], with an odds ratio of 1.23 [95% confidence interval, 1.08-1.41]). Three additional propensity score methods produced essentially similar results. The risk of serious adverse events did not significantly differ between the two groups. CONCLUSION This retrospective study revealed an association between acupuncture and an increased LBR among patients undergoing COH, and that acupuncture is a safe and valuable treatment option.

Obesity, as a chronic recurrent disease, has become a major public health challenge in China. To implement the requirements of the Healthy China Initiative (2019—2030), under domestic guidelines or consensus statements on overweight and obesity, and in alignment with the latest scientific advances globally, the Quality control protocol for adult overweight and obesity screening in health management (examination) institutions (2025 edition) was developed. This protocol was drafted by the Health Management Center of Shanghai Changzheng Hospital and formulated through multiple rounds of deliberation by experts in China’s health examination quality control field. The protocol establishes unified standards for screening facilities, personnel qualifications, and measurement or testing procedures. It defines specific screening items, outlines a standardized screening pathway, and sets requirements for the final medical review, ensuring the scientific validity, effectiveness, and safety of the screening process. The implementation of this protocol will enhance the consistency of weight management practices for adults across health examination institutions and strengthen the quality control of overweight and obesity screening programs.

DNA replication is a fundamental DNA metabolism process in living organisms. In human cells, thousands of DNA replication origins are activated simultaneously within the chromatin environment to initiate the replication process and eventually complete genome duplication. This process is regulated by the chromatin environment and coordinated with other chromatin metabolism events, ensuring accurate inheritance of genomic and epigenetic information. With the rapid development of research techniques and the massive accumulation of research data, the systematic understanding of DNA replication in eukaryotic cells, especially in mammals, within complex chromatin environments is a future research trend. Here, we review the multilayered regulatory modes of DNA replication from initiation to termination in the chromatin environment, offering insights for future research.

Objective To analyze the prognosis and influencing factors in patients with radioiodine-refractory differentiated thyroid cancer (RAIR-DTC). Methods A retrospective analysis was conducted on 52 patients with RAIR-DTC who underwent ineffective ¹³¹I therapy at the Department of Nuclear Medicine, Cancer Hospital, Chinese Academy of Medical Sciences from October 2016 to January 2020. Patients were categorized into progression and stable groups based on disease progression within five years post-treatment. Differences between groups were analyzed using chi-square test and logistic regression. Independent prognostic risk factors were identified using a Cox proportional hazards model. The Kaplan-Meier method with log-rank test was used to evaluate the impact of treatment on the prognosis of the progression group. Results The 3-year and 5-year survival rates of the 52 patients with RAIR-DTC were 88.5% and 73.1%, respectively. In the progression group, the rates were 81.8% and 57.6%. In the stable group, the rates were 100% and 100%. There were significant differences between the two groups in terms of age, presence of extrathyroidal extension, and the initial ¹³¹I treatment dose (P < 0.05). Univariate analysis indicated that the age, pre-ablation stimulated thyroglobulin level before the first ¹³¹I treatment, the neutrophil-to-lymphocyte ratio before the first treatment, and the sites of recurrence and metastasis were significantly associated with overall survival (P < 0.05). Multivariate analysis showed that age > 55 years (HR=12.40, 95% CI= 2.09-73.57, P=0.001) and distant metastasis (HR=24.47, 95% CI=4.17-143.75, P < 0.001) were independent risk factors for poor prognosis. Kaplan-Meier curve analysis showed that local surgery and/or targeted therapy significantly prolonged progression-free survival in the progression group (P < 0.001). Conclusion The prognosis for RAIR-DTC is poor, with advanced age and distant metastasis significantly associated with unfavorable outcomes. In elderly patients and those with extrathyroidal invasion, the treatment dose during initial ¹³¹I therapy may be appropriately increased to delay disease progression. For patients with disease progression, prompt local surgical intervention and/or targeted therapy is recommended.

Objective To construct a risk prediction model for liver cancer in patients with chronic hepatitis C based on seven different machine learning algorithms and select the optimal model. Methods A total of 236 patients with chronic hepatitis C were selected as the research subjects. Patients were divided into a case group and a control group according to whether liver cancer occurs. Prediction models were constructed based on seven machine learning algorithms including classification and regression tree, random forest, gradient boosting decision tree, extreme gradient boosting (XGBoost), logistic regression, K-near neighbor, and support vector machine. The Shapley additive explanations (SHAP) algorithm was used to interpret the best prediction model. Results Among the seven models, the XGBoost model had the best comprehensive prediction performance (accuracy of 0.933, sensitivity of 0.775, specificity of 0.960, area under the ROC curve of 0.956, F1 score of 0.764). The SHAP algorithm suggested that AFP, age, AST, diabetes, BMI, PLT, ALT, liver cysts, FIB-4, and gender contributed to the model decision and are the risk factors for liver cancer in patients with chronic hepatitis C. Conclusion This study develops an interpretable machine learning model based on the XGBoost algorithm, which has a good reference value for individualized monitoring of liver cancer in patients with chronic hepatitis C.

ObjectiveTo establish an analytical method for the determination of resorcinol, ferulic acid, phenethylresorcinol and benzoyl peroxide in freckle whitening cosmetics by high performance liquid chromatography (HPLC), to provide data support for the establishment of cosmetics inspection methods and technical support for the supervision of the cosmetics industry. MethodsThe analytes in samples were extracted by ultrasonic acetonitrile after methanol vortex, and then filtered by centrifugation and microporous filter membrane. Finally, the analytes were separated with a SVEA C4 column (250 mm×4.6 mm, 5 μm). The mobile phase was composed of 0.1% phosphoric acid solution -acetonitrile, and the gradient elution was applied, with a flow rate of 1.0 mL·min^-1. The samples were detected by an ultra-violet detector and quantified by external standard method. ResultsResorcinol, ferulic acid, phenylethylresorcinol and benzoyl peroxide showed good linearity in the experimental range with r>0.999. HPLC was used to investigate the positive spiked recoveries of ferulic acid or phenylethylresorcinol with different matrices. The results showed that the recoveries were all in the range of 87.48% to 101.00%, and the relative standard deviations were all in the range of 3.4% to 4.1%. Furthermore, HPLC also examined the blank matrix spiked with the recoveries ranged from 93.26% to 107.66%, with the relative standard deviation of 0.90% to 2.90%. The limits of detection ranged from 0.000 8% to 0.002%. Among the30 batches of standard freckle whitening cosmetics determined, 6 batches of which were detected with phenethylresorcinol and 1 batch with ferulic acid. ConclusionHPLC is a method with rapidity, simplicity, and high sensitivity, which is suitable for the simultaneous determination of resorcinol, ferulic acid, phenethylresorcinol and benzoyl peroxide in commercially available cosmetics.
