ObjectiveTo investigate the effect and mechanism of Yijingtang (YJT) in treating diminished ovarian reserve (DOR) in rats by regulating the Toll-like receptor 4 (TLR4)/myeloid differentiation factor 88 (MyD88)/nuclear factor-κB (NF-κB) signaling pathway. MethodsFifty female SD rats with normal estrous cycles were randomly allocated into blank, model, low- and high-dose (12.579 and 25.158 g·kg-1, respectively) YJT, and dehydroepiandrosterone (7.487 5 mg·kg-1) groups, with 10 rats in each group. The rats in other groups except the blank group were administrated with the tripterygium glycosides tablet suspension (5 mg·kg-1) by gavage for 14 days for the modeling of DOR. The rats in the drug treatment groups were administrated with corresponding drugs by gavage from day 15 for 30 consecutive days, and those in the blank and model groups received equal volumes of distilled water. The vaginal exfoliated cell smears were observed to assess the changes in the estrous cycle. The wet weight of bilateral ovaries was weighed for calculation of the ovarian index. Hematoxylin-eosin staining was performed to observe the histopathological changes in the ovaries and the proportions of follicles at various levels were calculated. The serum levels of sex hormones [follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2), and anti-Müllerian hormone (AMH)] and inflammatory factors [tumor necrosis factor-alpha (TNF-α), interleukin-1beta (IL-1β), and interleukin-10 (IL-10)] were determined by enzyme-linked immunosorbent assay. Real-time quantitative polymerase chain reaction(Real-time PCR) was conducted to determine the mRNA levels of TLR4, MyD88, NF-κB profilin α (IκBα), NF-κB and inflammatory factors in the ovarian tissue. Western blot was employed to measure the protein levels of factors related to the TLR4/MyD88/NF-κB signaling pathway in the ovarian tissue. Immunofluorescence (IF) was used to detect the nuclear translocation of NF-κB p65 in the ovarian tissue. ResultsCompared with the blank group, the model group showed disturbed estrous cycles, increased inflammatory infiltration in the ovarian tissue, decreases in ovarian index and proportion of presinusoidal follicles, and an increase in the proportion of atretic follicles (P<0.05, P<0.01). In addition, the model group showed elevated serum levels of FSH, LH, TNF-α, and IL-1β, up-regulated mRNA levels of TLR4, MyD88, IκBα, NF-κB, TNF-α, and IL-1β and protein levels of TLR4, MyD88, p-IκBα, and p-NF-κB p65 (P<0.01), lowered serum levels of AMH, E2, and IL-10, down-regulated mRNA level of IL-10 (P<0.01), and massive nuclear translocation of NF-κB p65 in the ovarian tissue. Compared with the model group, dehydroepiandrosterone and low and high doses of YJT restored the disturbed estrous cycle, reduced inflammatory infiltration in the ovarian tissue, increased the ovarian index (P<0.01), and changed the follicular composition ratio (P<0.01). Furthermore, the drugs lowered the serum levels of FSH, LH, TNF-α, and IL-1β, down-regulated the mRNA levels of TLR4, MyD88, IκBα, NF-κB, TNF-α, and IL-1β and the protein levels of TLR4, MyD88, p-IκBα, and p-NF-κB p65 (P<0.05, P<0.01), raised the serum levels of AMH, E2, and IL-10, up-regulated the mRNA level of IL-10 (P<0.05, P<0.01), and reduced the nuclear translocation of NF-κB p65 in the ovarian tissue. ConclusionYJT may inhibit the release and expression of inflammatory factors by regulating the TLR4/MyD88/NF-κB signaling pathway to attenuate the inflammatory responses in the ovarian tissue, thereby improving the ovarian function in DOR rats.

Rheumatoid arthritis (RA) represents a persistent autoimmune condition distinguished by a multifaceted etiology that encompasses both genetic and environmental factors. Recent progress in understanding the mechanisms behind RA pathogenesis has delved into the critical role of epigenetic regulatory processes, including DNA methylation, histone modifications, and the regulation by microRNAs (miRNAs). These findings provide new insights into the intricate nature of RA and pave the way for innovative therapeutic strategies. This review consolidates the latest developments in the epigenetic regulation of RA, concentrating on how these mechanisms affect the dysregulated signaling pathways associated with the disease. We analyze the roles of specific proteins that function as 'writers', 'erasers', and 'readers' in epigenetic modifications, highlighting their potential as targets for therapeutic intervention. Additionally, in view of the significance of miRNAs in the pathogenesis of RA, we deliberate on their involvement in disease progression and explore miRNA-based treatment strategies. By integrating these diverse epigenetic dimensions, this review offers a comprehensive epigenetic perspective on RA pathogenesis and identifies promising avenues for future research and therapeutic interventions.

The clinical efficacy advantages of traditional Chinese medicine (TCM) compound prescriptions have always been inadequately characterized in experimental research,which has become a bottleneck restricting the development of TCM pharmacology and even the progress of TCM. The concept of simultaneous treatment/regulation,guided by the theory of mutual generation and restriction of five zang-organs,has guiding significance in the clinical practice of TCM throughout history and is still widely used in the current clinical practice. However,this unique and clinically valuable diagnostic and therapeutic medication system based on the syndrome differentiation has been completely ignored in the modern research of TCM pharmacology,which might be one of the key factors restricting the pharmacological characterization of the therapeutic advantages of TCM compound prescriptions. On the basis of systematically summarizing the phased progress and achievements of the efficacy evaluation of TCM compound prescriptions,this article explores the path of exploring the pharmacological advantages of TCM compound prescriptions on simultaneous treatment/regulation on the basis of the correlation patterns of five zang-organs,from the theory of Zangxiang,the core concept of five zang-organs,and the TCM disease recognition based on the theory of mutual generation and restriction of five zang-organs. With the heart-lung correlation as a breakthrough point,this study explored a new characterization method for the pharmacological advantages of TCM,aiming to provide new ideas for evaluating the efficacy of TCM compound prescriptions.

With the rapid development of social economy, the number of patients with nervous system diseases has increased, and the incidence of the population has a trend of younger, which has a serious impact on life health and social economy. Artemisinin is an active antimalarial component extracted and isolated from Artemisia annua, a Chinese medicinal material. Artemisinin and its derivatives, in addition to the antimalarial effect, also have anti-parasitic, anti-fungal, anti-viral, hypoglycemic, hypolipidemic, anti-tumor, and anti-inflammatory effects, showing a wide range of pharmacological activities. In the past five years, research on the new pharmacological effects of artemisinin and its derivatives has been deepening, and the efficacy of artemisinin and its derivatives in nervous system diseases has attracted much attention, including anti-neuroinflammation, anti-oxidative stress, maintaining the stability of the blood-brain barrier, regulating the release of neurotransmitters, repairing neuronal damage, and promoting neuronal regeneration. These pharmacological effects indicate that artemisinin and its derivatives are potentially capable of neuroprotection. By sorting out literature on the pharmacological activity of artemisinin and its derivatives in nervous system during 2019-2024, this paper systematically summarized the protective effects of artemisinin and its derivatives against nervous system diseases such as stroke, neurodegenerative diseases, neuroimmunological diseases, neuralgia, and nervous system tumors. This review is expected to provide clues and evidence for new indication expansion of artemisinin drugs, innovative drug development, and clinical treatment of nervous system diseases.

The impact of air pollution on human health has always been a research hotspot in the global health field. Outdoor air pollutants composed of multiple components can enter the human body through various pathways. Cardiovascular diseases are a group of diseases caused by outdoor air pollutants. Studies have shown that the incidence of cardiovascular diseases, including hypertension, arrhythmia, and heart failure, is significantly increased among people exposed to air pollution environments. Air pollutants such as fine particulate matter, nitrogen dioxide, ozone, carbon monoxide, and sulfur dioxide are closely related to the occurrence of cardiovascular diseases, and short-term and long-term exposure causes different cardiovascular risks. By reviewing the relevant research reports from 2019 to 2024, this article summarizes the epidemiological evidence of cardiovascular diseases caused by different air pollutants. It generalizes the pathways through which air pollutants accelerate the progression of cardiovascular diseases. These pathways include oxidative stress, inflammatory response, thrombosis, extracellular vesicle release, endoplasmic reticulum stress, apoptosis, endothelial dysfunction, autonomic nervous system imbalance, and their interactions. Based on the different mechanisms of air pollution on cardiovascular diseases, the article analyzes the main progress in drug intervention and summarizes the roles of various active ingredients and compound prescriptions of traditional Chinese medicine in treating air pollution-related cardiovascular diseases, providing reference for the research on the mechanisms and drug interventions of air pollution-related cardiovascular diseases.

The complex pathophysiological mechanisms between diabetes mellitus and cardiovascular diseases have not yet been fully elucidated, becoming one of the challenges in clinical care. Glucagon-like peptide-1 receptor agonist (GLP1-RA) and sodium glucose cotransporter-2 inhibitors (SGLT2) are clinically used to reduce the cardiovascular risk of patients with diabetes mellitus. Traditional Chinese medicine has diverse biological activities and unique advantages in the treatment of chronic complex diseases due to its multi-component and multi-target effects. Based on recent reports, this paper reviewed the common risk factors of diabetes mellitus and cardiovascular diseases (e.g., hyperglycemia, insulin resistance, and inflammation), related targets such as apolipoprotein C-Ⅲ (APOC3), S100 calcium-binding protein A8/A9 (S100A8/A9), growth/differentiation factor-15 (GDF-15), and NACHT, LRR, and PYD domains-containing protein 3 (NLRP3), advanced glycation end products, insulin resistance, endothelial dysfunction, endoplasmic reticulum stress, mitochondrial dysfunction, and intestinal flora disorder. In addition, this paper summarized the research progress in the treatment of cardiovascular diseases in diabetes mellitus with the active ingredients (e.g., baicalein, puerarin, curcumin, notoginsenoside, and tanshinone ⅡA), single herbal medicines (e.g., Astragali Radix, Ginseng Radix et Rhizoma, Sophorae Flavescentis Radix, Cinnamomi Cortex, and Corni Fructus), and compound formulas (e.g., Buzang Tongluo Fang, Yiqi Yangyin Huoxue Fang, Shenqi Fang, Huangqisan, Danggui Buxue Tang, and Liuwei Dihuang Wan) of traditional Chinese medicine. Traditional Chinese medicine mainly treats cardiovascular diseases in diabetes mellitus by reducing inflammation and oxidative stress, ameliorating dyslipidemia and insulin resistance, protecting islet β cell function, repairing endothelial damage, inhibiting smooth muscle cell proliferation, foam cell formation, macrophage polarization, and cardiac hypertrophy and fibrosis, and regulating intestinal flora disorder. These processes involve insulin receptor substrate/ phosphatidylinositol 3-kinase/protein kinase B (IRS/PI3K/Akt), peroxisome proliferator-activated receptor α/γ (PPAR α/γ), nuclear factor-kappa B (NF-κB), adenosine 5′-monophosphate (AMP)-activated protein kinase (AMPK), hypoxia-inducible factor-1-BCH domain-containing protein (HIF-1-BNIP), vascular endothelial growth factor/hypoxia-inducible factor-1α (VEGF/HIF-1α) and other signaling pathways. This review is expected to provide a theoretical basis and reference for the treatment of cardiovascular diseases in diabetes mellitus with traditional Chinese medicine.

Objective:To explore the clinical feasibility of finger-pressing therapy based on the theory of treating impotence alone with Yang Ming to reduce incidence of ICU acquired weakness (ICU-AW) in critically ill children and provide a feasible nursing plan for ICU acquired asthenia in critically ill children.Methods:A quasi-experimental study was conducted. A total of 73 critically ill children were admitted to the PICU of Kunming Children′s Hospital from January 1 to April 30, 2021. According to the random number table, the subjects were divided into the observation group (37 cases) and the control group (36 cases). Children in the control group received routine PICU nursing. The children in the observation group were treated with PICU routine nursing and finger-pressing therapy based on the theory of treating impotence alone with Yang Ming. The two groups were compared in terms of limb muscle strength score (MRC-Score), incidence of ICU-AW, basic activities of life (Barthel Index, BI), limb muscle thickness.Results:After intervention, the MRC-Score of the observation group was 50 (46, 52) points, which was higher than 46 (40, 48) points of the control group, and the difference between the two groups was statistically significant ( Z=-3.70, P<0.05). The incidence of ICU-AW in the observation group was 32.43% (12/37), and the incidence of ICU-AW in the control group was 72.22% (26/36). The difference between the two groups was statistically significant ( χ2=11.58, P<0.05). The BI score of the observation group was 63 (50, 70), which was higher than 44 (40,60) of the control group, and the difference between the two groups was statistically significant ( Z=-3.94, P<0.05). The reduction degree of quadriceps femoris thickness in the observation group at D3-D1 was (-0.381 ± 0.131) cm, which was lower than (-0.762 ± 0.182) cm in the control group, and the difference between the two groups was statistically significant ( t=10.29, P<0.05). Conclusions:The application of finger-pressing therapy guided by theory of treating impotence alone with Yang Ming in the early rehabilitation of critically ill children can enhance muscle strength, prevent muscle atrophy and reduce the incidence of ICU-AW in critically ill children.

Objective:To evaluate the clinic efficacy of channel bone grafting [preservation of the sclerotic bone at the broken nonunion ends and fixation with limited contact dynamic compression plate (LC-DCP)] in the treatment of postoperative atrophic nonunion of middle clavicular fracture.Methods:The 41 patients were retrospectively analyzed who had been treated at Department of Orthopaedics and Traumatology, Xi'an Hong-Hui Hospital for atrophic nonunion after internal fixation of middle clavicular fracture from June 2015 to December 2019. They were 23 males and 18 females, with a mean age of 47.6 years (from 28 to 63 years). The left side was affected in 25 cases and the right side in 16 cases. The time interval between initial fracture surgery and nonunion surgery averaged 18.5 months (from 9 to 40 months). Thirty-six cases had undergone one operation and 5 cases 2 operations before admission. The length of bone defect was measured during operation. All nonunions were treated with construction of a graft channel, iliac bone graft and LC-DCP internal fixation above the clavicle. The upper limb function of the affected side was evaluated by the Disabilities of Arm, Shoulder and Hand (DASH) 12 months after operation.Results:The 41 patients were followed up for an average of 13.6 months (from 12 to 15 months). A bone defect ≤2.0 cm was found in 25 cases and that >2.0 cm in 16 ones. Nonunion healed in all patients after an average time of 14 weeks (from 12 to 16 weeks). One patient reported continuous pain in the donor area after operation and the other developed deep venous thrombosis at the right lower limb. The DASH upper limb scores at 12 months after operation averaged 14.7.Conclusion:Channel bone grafting is a feasible clinical treatment of postoperative atrophic nonunion of middle clavicular fracture, because it preserves the sclerotic bone at the broken nonunion ends, reduces the amount of iliac bone graft and leads to fine clinic efficacy.

Objective:Based on the data of Global Burden of Disease 2019 data, to analyze the past, current, and future burden of disability-adjusted life years (DALYs) in China and compare with the international status.Methods:The total number of DALYs, age-standardized DALY rate, and the composition of different subgroups were extracted and described to analyze the time trend in 2000-2019 and the current situation in 2019 for Chinese female breast cancer. The burden of DALYs in 2050 was predicted by Joinpoint using average annual percent change (AAPC).Results:In 2000-2019, the ranking of DALYs caused by female breast cancer in China rose from the fourth to the second in all female cancers. The total DALYs increased by 48.4%, of which the years lived with disability increased from 4.8% to 8.8%. The age-standardized DALY rate only slightly decreased (AAPC=-0.3%; which increased during 2016-2019, AAPC=1.6%). In 2019, the age-standardized DALY rate for breast cancer in China was 278.0/100 000. The DALYs were 2.88 million (accounting for 14.2% of the global burden and 12.1% of all female cancers burden in China), 26.5% of which attributed known risk factors (overweight and obesity were the largest: 0.34 million DALYs, but some common breast cancer risk factors were not available on the platform, such as menstruation and fertility). In 2050, the prediction suggests that the total DALYs caused by female breast cancer in China will reach 3.80 million person-years-5.16 million person-years, increasing 32.1%-79.4% over 2019. From 2000 to 2019, the peak age of DALYs and DALY rate became older, and the DALYs among females aged 65 years and above increased faster than those younger than 65 years (AAPC were 4.8% and 1.3%, respectively). In 2019, females aged 45-74 (the starting age recommended by local guidelines for breast cancer screening) contributed 74.3% of the total DALYs.Conclusions:Over the past 20 years, the age-standardized DALY rate for breast cancer in female populations in China has not changed obviously. Without the continuous expansion of effective intervention and population aging, the burden of DALYs for female breast cancer in China will increase. DALYs for breast cancer attributed leading risk factors were still limited.
