epsis is a systemic inflammatory response syndrome triggered by infection， and its high mortality rate is closely associated with immune imbalance， particularly the imbalance in the differentiation of helper T cell （Th） cell subsets [Th1， Th2， Th17， regulatory T cell （Treg） ] . In recent years， traditional Chinese medicine （TCM）， with its characteristics of multi-component and multi-target actions， has demonstrated unique advantages in regulating Th cell differentiation and function， as well as correcting immune imbalances in sepsis， offering new perspectives for immunotherapy of sepsis. This review summarizes relevant studies on the regulation of Th cell differentiation for sepsis treatment by TCM monomers and active ingredients （such as Astragalus membranaceus ， Scutellaria baicalensis ， Coptis chinensis ， Rheum palmatum ， Ganoderma lucidum ， Ginkgo biloba ， and Cistanche deserticola ）， the alcohol extract of Dai Baijie， and TCM formulas and preparations categorized as blood-activating and stasis-removing， purgative and laxative， warming and tonifying yang， and tonifying qi and nourishing yin. The results indicate that these TCM monomers， active ingredients， extracts， formulas， and preparations can regulate the Th1/Th2 and Th17/Treg balance， target the differentiation balance of Th cell subsets， alleviate inflammatory responses， or improve immune suppression， thereby exerting therapeutic effects on sepsis.

Osteonecrosis of femoral head （ONFH） is a disease that causes osteocyte death due to interruption of blood supply of the femoral head， which may cause symptoms such as joint movement disorders， pain， and even femoral head collapse. Currently， the commonly used methods for treating ONFH in clinical practice are accompanied by problems such as long-term side effects， inaccurate efficacy， technical limitations， and complication risks. Traditional Chinese medicine （TCM） has shown unique advantages of holistic regulation， mild side effects， and symptom alleviation. A review of the related literature shows that Salviae Miltiorrhizae Radix et Rhizoma， as a representative Chinese herbal medicine for activating blood and resolving stasis， has the effects of activating blood， resolving stasis， dredging meridians， and relieving pain. Its active ingredients （such as salvianolic acid B， tanshinone Ⅱ_A， and tanshinone Ⅰ） interfere with bone metabolism balance， osteogenesis and differentiation， and improve bone microcirculation and bone microstructure. Salviae Miltiorrhizae Radix et Rhizoma is often combined with the herbal medicines with the effects of tonifying the liver and spleen or activing blood to form herb pairs （such as Salviae Miltiorrhizae Radix et Rhizoma-Angelicae Sinensis Radix， Salviae Miltiorrhizae Radix et Rhizoma-Chuanxiong Rhizoma， and Salviae Miltiorrhizae Radix et Rhizoma-Drynariae Rhizoma）， which enhances the efficacy through synergistic effects. In the application of TCM compound formulas， Bushen Huoxue prescription， Bushen Huoxue capsules， Gubi Tongxiao granules， and Shenggu Zaizao pills can regulate signaling pathways such as Wnt/β-catenin， Hedgehog， Notch， transforming growth factor（TGF）-β₁/Smads， and mitogen-activated protein kinase （MAPK） through multiple targets to significantly improve bone metabolism and hip joint function， playing an important role in preventing and treating ONFH. Through a review of available studies， this paper systematically explains the outstanding advantages of the active ingredients， herb pairs， and compound formulas of Salviae miltiorrhizae Radix et Rhizoma in the prevention and treatment of ONFH. The mechanisms may be related to factors such as promoting osteoblast generation and inhibiting osteoclast formation， increasing osteogenic differentiation， promoting angiogenesis， increasing bone density， inhibiting inflammatory response， and regulating signaling pathways. In the future， modern technology can be employed to optimize dosage forms， and high-quality clinical research should be conducted to further clarify its mechanism of action and promote the precise application of TCM. This review aims to provide more thinking directions for the application of Salviae miltiorrhizae Radix et Rhizoma in preventing and treating ONFH.

Sepsis is a systemic inflammatory response syndrome triggered by infection. It progresses rapidly and tends to develop into multiple organ dysfunction. Tanshinone ⅡA， one of the core active ingredients of Salvia miltiorrhiza， exerts remarkable targeted protective effects against sepsis-induced multiple organ dysfunction. This paper reviews the mechanisms by which tanshinone ⅡA alleviates sepsis-induced multiple organ dysfunction. Tanshinone ⅡA can relieve sepsis-induced lung injury by inhibiting the activity of Toll-like receptor 4/myeloid differentiation primary response protein 88/nuclear factor- κB， phosphatidylinositol 3-kinase/protein kinase B signaling pathways and maintaining mitochondrial homeostasis. It ameliorates sepsis- induced myocardial injury via suppressing the activation of NOD-like receptor family pyrin domain-containing 3/caspase-1 signaling pathway， downregulating the expression of inflammatory factors and regulating autophagy. It mitigates sepsis-induced renal injury by regulating oxidative stress imbalance and reducing the expression of apoptosis-related proteins. It alleviates sepsis-caused liver injury through inhibiting the release of inflammatory factors and hepatocyte apoptosis. It improves sepsis-induced intestinal barrier dysfunction by upregulating the expression of tight junction proteins and restraining inflammatory responses. Furthermore， it relieves sepsis-associated encephalopathy by activating peroxisome proliferator-activated receptor gamma coactivator-1α/nuclear respiratory factor 1/mitochondrial transcription factor A signaling pathway. Tanshinone ⅡA is expected to be a vital candidate drug for comprehensive prevention and treatment of sepsis. However， interdisciplinary research is required to break through current bottlenecks and realize the transformation from basic experiments to clinical application.

Background The health effects of environmental exposures are often characterized by complex interactions. However, evidence on the joint health effects of ambient oxidizing pollutants and air temperature in the cold regions of Northern China remains limited. Objective To examine the independent and interactive effects of atmospheric oxidizing pollutants and air temperature on daily mortality among residents of Hohhot. Methods Daily data on air quality, meteorological factors, and cause-specific mortality in Hohhot from 2018 to2023 were collected. A quasi-Poisson generalized additive model (GAM) combined with a distributed lag non-linear model (DLNM) was used to examine the effects of ambient oxidant pollutants [ozone (O₃), nitrogen dioxide (NO₂), and total oxidant (Oₓ)] and air temperature on daily circulatory and respiratory mortality. Potential interactions between oxidizing pollutants and temperature were evaluated using bivariate exposure–response surface models and quantified through stratified analyses. Results For each 10 μg·m⁻³ increase in O₃, O_X, and NO₂ concentrations, the strongest associations with circulatory disease mortality occurred at lag1, with excess risks (ERs) of 1.10% (95%CI: 0.50%, 1.71%), 1.84% (95%CI: 0.94%, 2.75%), and 1.49% (95%CI: 0.36%, 2.62%), respectively. The strongest associations of O₃ and O_X with respiratory disease mortality were observed at lag2, with ERs of 1.61% (95%CI: 0.61%, 2.62%) and 2.61% (95%CI: 1.61%, 3.62%), respectively. NO₂ showed the strongest cumulative association with respiratory disease mortality at lag02, with an ER of 3.22% (95%CI: 1.24%, 5.25%). High temperature exhibited immediate or short-term effects, while low temperature showed lagged effects. The exposure–response relationships between temperature and mortality risks for respiratory circulatory diseases were U-shaped. Positive additive interactions were observed between high temperature and high concentrations of O₃ and O_X. For the joint exposure to high temperature and high O₃, the relative excess risks due to interaction (RERIs) for circulatory and respiratory disease mortality were 0.131 (95%CI: 0.086, 0.176) and 0.279 (95%CI: 0.198, 0.360), respectively. For the joint exposure to high temperature and high O_X, the corresponding RERI values were 0.080 (95%CI: 0.038, 0.123) and 0.154 (95%CI: 0.074, 0.234), respectively. In contrast, high temperature and high NO₂ concentration exhibited antagonistic or attenuating interactions. Conclusion Ambient oxidizing pollutants, high temperature, and low temperature are independently associated with increased circulatory and respiratory disease mortality. High temperature combined with high concentrations of O₃ or O_X exerts positive additive interactions, with the respiratory system showing particular vulnerability. The mortality risks associated with NO₂ are more pronounced under low temperature conditions, whereas its interaction with high temperature appear antagonistic, suggesting a temperature-dependent risk-modifying effect.

Sensorineural hearing loss (SNHL), the most commonly-occurring form of hearing loss, is caused mainly by injury to or the loss of hair cells and spiral ganglion neurons in the cochlea. Numerous environmental and physiological factors have been shown to cause acquired SNHL, such as ototoxic drugs, noise exposure, aging, infections, and diseases. Several programmed cell death (PCD) pathways have been reported to be involved in SNHL, especially some novel PCD pathways that have only recently been reported, such as ferroptosis, necroptosis, and pyroptosis. Here we summarize these PCD pathways and their roles and mechanisms in SNHL, aiming to provide new insights and potential therapeutic strategies for SNHL by targeting these PCD pathways.
