ObjectiveTo investigate the mechanism of Zuogui Wan (ZGW) in improving ovarian inflammatory microenvironment and stemness of ovarian germline stem cells (OSCs) for treating ovarian aging via the cyclic guanosine monophosphate/adenosine monophosphate synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway. MethodsForty C57BL/6 female mice were randomly divided into a blank group, a model group, a low-dose ZGW group (2.7 g·kg-1), a high-dose ZGW group (5.4 g·kg-1), and an estradiol valerate group (0.15 mg·kg-1), with 8 mice in each group. Except the blank group, all other groups received a single intraperitoneal injection of cyclophosphamide at 120 mg·kg-1 to establish an ovarian aging mouse model. After successful modeling, each group was continuously administered for 4 weeks, once daily. The physiological status of the mice was observed, and the ovarian index was calculated. The estrus cycle of the mice was monitored. Hematoxylin-eosin (HE) staining was used to observe pathological changes in ovarian tissue. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum sex hormone levels. Serum inflammatory factors interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and mouse interleukin-6 (IL-6) levels were detected using kits. Western blot was used to detect the protein expression of ovarian cGAS, STING, p-STING, TANK-binding kinase 1 (TBK1), p-TBK1, interferon-induced transmembrane protein 3 (Fragilis), and Vasa homolog protein (MVH). Quantitative real-time polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of inflammatory factors in ovarian tissue. Immunofluorescence double labeling was performed to locate OSCs in ovarian tissues, and fluorescence intensities of OSCs markers MVH and octamer binding transcription factor 4 (Oct4) were calculated. ResultsCompared with the blank group, the model group showed reduced body weight, ovarian wet weight, and ovarian index (P<0.01) and a disordered estrus cycle (P<0.01). In addition, the levels of serum follicle-stimulating hormone (FSH), TNF-α, IL-6, and IL-1β were increased (P<0.01), while anti-Müllerian hormone (AMH) and estradiol (E2) levels were decreased (P<0.01). The protein expression of cGAS, p-STING/STING, and p-TBK1/TBK1 in ovarian tissue was increased (P<0.05, P<0.01), while that of OSCs stemness factors MVH and Fragilis was reduced (P<0.01). Immunofluorescence indicated a reduction in MVH and Oct4 expression in OSCs (P<0.01). The mRNA expression of inflammatory factors TNF-α, IL-6, and IL-1β in ovarian tissue was increased (P<0.05, P<0.01). Compared with the model group, the treatment groups exhibited improved body weight, ovarian wet weight, and ovarian index (P<0.05) and a reduced rate of estrus cycle disorder (P<0.05, P<0.01). The levels of serum FSH, TNF-α, IL-6, and IL-1β were decreased (P<0.05, P<0.01), while AMH and E2 levels were increased (P<0.01). The protein expression levels of cGAS, p-STING/STING, and p-TBK1/TBK1 in ovarian tissue were decreased (P<0.05), while the protein expression of MVH and Fragilis was increased (P<0.05), and the fluorescence intensities of MVH and Oct4 were increased (P<0.05, P<0.01). The mRNA expression of inflammatory factors in ovarian tissue was decreased (P<0.05). ConclusionZGW alleviate ovarian inflammatory response, regulate ovarian microenvironment homeostasis, and maintain stemness of OSCs in ovarian aging mice probably by modulating the cGAS-STING signaling pathway, thereby improving ovarian function and delaying ovarian aging.

Objective:
This study explored whether anxiety and core self-evaluation mediate the relationship between negative life events and depressive symptoms in adolescents of the Yi ethnic minority in China.
Methods:
In this cross-sectional study, a convenience sample of 627 Yi adolescents 10–19 years old (252 males, 40.2%) from primary, middle and high schools in Liangshan Prefecture in China completed the Adolescent Self-Rating Life Events Checklist (ASLEC) to report on negative life events, the Second Edition of the Beck Depression Inventory (BDI-II) to report on depressive symptoms, the Core Self-Evaluations Scale (CSES) to describe core self-evaluation, and the Screen for Child Anxiety-Related Emotional Disorders (SCARED) to report anxiety symptoms.
Results:
In Pearson correlation analysis, total score and dimension subscores on the ASLEC correlated positively with total score and dimension subscores on the SCARED survey as well as with total score on the BDI. Total ASLEC score and dimension subscores correlated negatively with total CSES score. Mediation analysis indicated that negative life events affected depressive symptoms directly, as well as indirectly via core self-evaluation (mediating effect was 0.087; 95% confidence interval [CI], 0.063–0.113; p<0.001). The chain-mediated pathway effect was significant (mediating effect was 0.017; 95% CI, 0.011–0.026; p<0.001).
Conclusion
Yi adolescents in Liangshan Prefecture show certain prevalence of anxiety and depression, and they score relatively low on core self-evaluation. In this ethnic group, negative life events can affect depressive symptoms directly as well as indirectly through chain-mediated effects of anxiety and core self-evaluation.

The innate immune system can be boosted in response to subsequent triggers by pre-exposure to microbes or microbial products, known as “trained immunity”. Compared to classical immune memory, innate trained immunity has several different features. Firstly, the molecules involved in trained immunity differ from those involved in classical immune memory. Innate trained immunity mainly involves innate immune cells (e.g., myeloid immune cells, natural killer cells, innate lymphoid cells) and their effector molecules (e.g., pattern recognition receptor (PRR), various cytokines), as well as some kinds of non-immune cells (e.g., microglial cells). Secondly, the increased responsiveness to secondary stimuli during innate trained immunity is not specific to a particular pathogen, but influences epigenetic reprogramming in the cell through signaling pathways, leading to the sustained changes in genes transcriptional process, which ultimately affects cellular physiology without permanent genetic changes (e.g., mutations or recombination). Finally, innate trained immunity relies on an altered functional state of innate immune cells that could persist for weeks to months after initial stimulus removal. An appropriate inducer could induce trained immunity in innate lymphocytes, such as exogenous stimulants (including vaccines) and endogenous stimulants, which was firstly discovered in bone marrow derived immune cells. However, mature bone marrow derived immune cells are short-lived cells, that may not be able to transmit memory phenotypes to their offspring and provide long-term protection. Therefore, trained immunity is more likely to be relied on long-lived cells, such as epithelial stem cells, mesenchymal stromal cells and non-immune cells such as fibroblasts. Epigenetic reprogramming is one of the key molecular mechanisms that induces trained immunity, including DNA modifications, non-coding RNAs, histone modifications and chromatin remodeling. In addition to epigenetic reprogramming, different cellular metabolic pathways are involved in the regulation of innate trained immunity, including aerobic glycolysis, glutamine catabolism, cholesterol metabolism and fatty acid synthesis, through a series of intracellular cascade responses triggered by the recognition of PRR specific ligands. In the view of evolutionary, trained immunity is beneficial in enhancing protection against secondary infections with an induction in the evolutionary protective process against infections. Therefore, innate trained immunity plays an important role in therapy against diseases such as tumors and infections, which has signature therapeutic effects in these diseases. In organ transplantation, trained immunity has been associated with acute rejection, which prolongs the survival of allografts. However, trained immunity is not always protective but pathological in some cases, and dysregulated trained immunity contributes to the development of inflammatory and autoimmune diseases. Trained immunity provides a novel form of immune memory, but when inappropriately activated, may lead to an attack on tissues, causing autoinflammation. In autoimmune diseases such as rheumatoid arthritis and atherosclerosis, trained immunity may lead to enhance inflammation and tissue lesion in diseased regions. In Alzheimer’s disease and Parkinson’s disease, trained immunity may lead to over-activation of microglial cells, triggering neuroinflammation even nerve injury. This paper summarizes the basis and mechanisms of innate trained immunity, including the different cell types involved, the impacts on diseases and the effects as a therapeutic strategy to provide novel ideas for different diseases.

Journal of Geriatric Cardiology 2025;22(4):433-442
BACKGROUND:
The clinical impact of post-percutaneous coronary intervention (PCI) quantitative flow ratio (QFR) in patients treated with PCI for chronic total occlusion (CTO) was still undetermined.
METHODS:
All CTO vessels treated with successful anatomical PCI in patients from PANDA III trial were retrospectively measured for post-PCI QFR. The primary outcome was 2-year vessel-oriented composite endpoints (VOCEs, composite of target vessel-related cardiac death, target vessel-related myocardial infarction, and ischemia-driven target vessel revascularization). Receiver operator characteristic curve analysis was conducted to identify optimal cutoff value of post-PCI QFR for predicting the 2-year VOCEs, and all vessels were stratified by this optimal cutoff value. Cox proportional hazards models were employed to calculate the hazard ratio (HR) with 95% CI.
RESULTS:
Among 428 CTO vessels treated with PCI, 353 vessels (82.5%) were analyzable for post-PCI QFR. 31 VOCEs (8.7%) occurred at 2 years. Mean value of post-PCI QFR was 0.92 ± 0.13. Receiver operator characteristic curve analysis shown the optimal cutoff value of post-PCI QFR for predicting 2-year VOCEs was 0.91. The incidence of 2-year VOCEs in the vessel with post-PCI QFR < 0.91 (n = 91) was significantly higher compared with the vessels with post-PCI QFR ≥ 0.91 (n = 262) (22.0% vs. 4.2%, HR = 4.98, 95% CI: 2.32-10.70).
CONCLUSIONS
Higher post-PCI QFR values were associated with improved prognosis in the PCI practice for coronary CTO. Achieving functionally optimal PCI results (post-PCI QFR value ≥ 0.91) tends to get better prognosis for patients with CTO lesions.

OBJECTIVE:
To evaluate the efficacy and safety of Shexiang Tongxin Dropping Pill (STDP) in treating stable angina patients with phlegm-heat and blood-stasis syndrome by exercise duration and metabolic equivalents.
METHODS:
This multicenter, randomized, double-blind, placebo-controlled clinical trial enrolled stable angina patients with phlegm-heat and blood-stasis syndrome from 22 hospitals. They were randomized 1:1 to STDP (35 mg/pill, 6 pills per day) or placebo for 56 days. The primary outcome was the exercise duration and metabolic equivalents (METs) assessed by the standard Bruce exercise treadmill test after 56 days of treatment. The secondary outcomes included the total angina symptom score, Chinese medicine (CM) symptom scores, Seattle Angina Questionnaire (SAQ) scores, changes in ST-T on electrocardiogram and adverse events (AEs).
RESULTS:
This trial enrolled 309 patients, including 155 and 154 in the STDP and placebo groups, respectively. STDP significantly prolonged exercise duration with an increase of 51.0 s, compared to a decrease of 12.0 s with placebo (change rate: -11.1% vs. 3.2%, P<0.01). The increase in METs was significantly greater in the STDP group than in the placebo group (change: -0.4 vs. 0.0, change rate: -5.0% vs. 0.0%, P<0.01). The improvement of total angina symptom scores (25.0% vs. 0.0%), CM symptom scores (38.7% vs. 11.8%), reduction of nitroglycerin consumption (100.0% vs. 11.3%), and all domains of SAQ, were significantly greater with STDP than placebo (all P<0.01). The changes in Q-T intervals at 28 and 56 days from baseline were similar between the two groups (both P>0.05). Twenty-five participants (16.3%) with STDP and 16 (10.5%) with placebo experienced AEs (P=0.131), with no serious AEs observed.
CONCLUSION
STDP could improve exercise tolerance in patients with stable angina and phlegm-heat and blood stasis syndrome, with a favorable safety profile. (Registration No. ChiCTR-IPR-15006020).

Journal of Central South University(Medical Sciences) 2025;50(6):995-1001
OBJECTIVES:
Managing patients with refractory head and neck cancer pain is one of the more challenging issues in clinical practice, and traditional intrathecal drug delivery also fails to provide adequate analgesia. There are currently no comprehensive and effective treatment methods. This study aims to observe the efficacy and safety of treating intractable head and neck cancer pain with morphine pump via lumbar approach to the prepontine cistern.
METHODS:
A total of 18 patients with intractable head and neck cancer pain treated with prepontine cistern morphine pumps were selected from the Department of Pain Management, Second Xiangya Hospital, Central South University between September 2019 and July 2023. Statistical analysis was performed on patients' preoperative and postoperative (1 week, 1 month, and 2 months after surgery), Numerical Rating Scale (NRS) scores, Self-Rating Depression Scale (SDS) scores, daily oral morphine consumption, the number of daily breakthrough pain episodes, and postoperative daily intrathecal morphine dosage.
RESULTS:
The NRS scores, SDS scores, daily oral morphine consumption, and the number of daily breakthrough pain episodes of patients at each time point after surgery were significantly lower than before surgery (all P<0.05). With the gradual increase in the dosage of intrathecal morphine, the daily oral morphine consumption of patients at each postoperative time point was significantly reduced compared to preoperative levels (all P<0.05). The complications related to the operation were mild, including nausea in 5 cases (31.3%), headache in 2 cases (12.5%); hypotension, urine retention, hypersomnia and constipation in 1 case (6.3% each), and no serious adverse events occurred. All improved and were discharged after symptomatic treatment.
CONCLUSIONS
The implantation of prepontine cistern morphine pump effectively controls intractable head and neck cancer pain, demonstrating characteristics of minimal invasiveness, mild side effects, and low medication dosage under the premise of standardized procedures.
