Rice (Oryza sativa L.), as a thermophilic crop, is highly susceptible to cold stress during its growth process. Chilling injury at the plumule stage and seedling stage often affects the morphological development and leads to yield reduction of rice. The exploration and utilization of cold tolerance genes are among the most direct and effective approaches to address cold stress in rice. To identify quantitative trait loci (QTLs) associated with cold tolerance at plumule and seedling stages, in this study, we measured the seedling rates and survived seedling rates of the indica rice cultivar 'HZ', the japonica cultivar 'Nekken2', and their 120 recombinant inbred lines (RILs) under cold stress. A previously constructed high-density genetic linkage map was used for the mapping of the QTLs conferring cold tolerance at the plumule and seedling stages. A total of 4 QTLs for plumule-stage cold tolerance and 9 QTLs for seedling-stage cold tolerance were detected, with the maximum limit of detection reaching 5.20. Notably, a genetically overlapping QTL for both plumule and seedling stages was identified on chromosome 8, spanning a physical interval of 24 432 953-25 295 129 bp. Candidate genes within the detected QTL intervals were screened, and quantitative real-time polymerase chain reaction (qRT-PCR) was conducted to analyze the gene expression during the plumule and seedling stages. The results revealed that LOC_Os03g06570, LOC_Os03g07100, LOC_Os06g08280, LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540 exhibited significantly differential expression between the parental lines. These genes were either significantly downregulated or upregulated under cold stress. Among them, the first three gene (LOC_Os03g06570, LOC_Os03g07100, and LOC_Os06g08280) were hypothesized to be key candidates regulating the cold tolerance of rice seedlings, while the latter three genes (LOC_Os08g38440, LOC_Os08g39100, and LOC_Os08g39540) were identified as comprehensive regulators of cold tolerance during both plumule and seedling stages. These findings lay a foundation for the fine mapping and cloning of cold tolerance genes at the plumule and seedling stages, providing valuable insights for breeding cold-tolerant rice varieties.

Hepatocellular carcinoma (HCC) is a malignant tumor with high incidence and mortality rates worldwide. Recent studies have shown that neutrophil extracellular traps (NETs) play an important role in the development, progression, and immune escape of HCC. NETs are released by neutrophils and mainly consist of DNA, histones, and antimicrobial molecules, and in addition to immune defense, they are also involved in the initiation, metastasis, and thrombosis of HCC. This article elaborates on the formation and regulatory mechanisms of NETs, explores their potential mechanisms in the initiation, metastasis, immune escape, and thrombosis of HCC, and discusses the prospect of NETs as a target for the diagnosis and treatment of HCC, in order to provide new ideas for the precise treatment of HCC in the future and promote the early diagnosis and effective treatment of HCC.

With the increasing global recognition of Traditional Chinese Medicine (TCM), acupuncture, as a non-pharmacological treatment, has demonstrated promising potential in alleviating symptoms, improving quality of life, and modulating immune and neurological system functions in patients with Crohn's disease (CD). This review summarizes the theoretical foundations and recent research progress on acupuncture for CD, and introduces a personalized "Three Discriminations" diagnostic and therapeutic strategy based on syndrome differentiation, meridian differentiation, and acupoint selection. It also identifies the target patient populations and clinical application value of acupuncture in CD treatment. Despite preliminary progress, acupuncture treatment for CD still faces multiple challenges, including limited high-quality clinical research evidence, uneven resource distribution, non-standardized efficacy evaluation systems, insufficiently standardized treatment strategies, and an incomplete understanding of its underlying mechanisms. Future efforts should focus on establishing high-quality evidence systems, optimizing integrative treatment strategies combining acupuncture with conventional medicine, and conducting deep exploration of multi-dimensional mechanisms, with the goal of promoting the standardized integration of acupuncture into the management of CD and providing patients with safer, more precise, and sustainable therapeutic options.

Inflammaging is a process of cellular dysfunction associated with chronic inflammation, which plays a significant role in the onset and progression of liver diseases. Research on its mechanisms has become a hotspot. In viral hepatitis, inflammaging primarily involve oxidative stress, cell apoptosis and necrosis, as well as gut microbiota dysbiosis. In non-alcoholic fatty liver disease, inflammaging is more complex, involving insulin resistance, fat deposition, lipid metabolism disorders, gut microbiota dysbiosis, and abnormalities in NAD+ metabolism. In liver tumors, inflammaging is characterized by weakening of tumor suppressive mechanisms, remodeling of the liver microenvironment, metabolic reprogramming, and enhanced immune evasion. Therapeutic strategies targeting inflammaging have been developing recently, and antioxidant therapy, metabolic disorder improvement, and immunotherapy are emerging as important interventions for liver diseases. This review focuses on the mechanisms of inflammaging in liver diseases, aiming to provide novel insights for the prevention and treatment of liver diseases.

The shaoyang meridian is an important pivot between the internal organs and meridians system, with the functions of regulating qi and blood, balancing yin and yang, and coordinating the ascending and descending movement of qi. Dysfunction of the shaoyang pivot can lead to spleen and kidney deficiency, impaired liver and gallbladder qi regulation, and stagnation of qi and blood. It is believed that the onset and progression of Crohn's disease are closely related to shaoyang pivot dysfunction, with the core pathogenesis characterized by shaoyang disharmony, spleen deficiency, dampness retention, and blood stasis. Based on this understanding, the treatment principle centers on harmonizing the shaoyang pivot, supplemented by methods such as warming and nourishing the spleen and stomach, tonifying shaoyang, and soothing the liver and benefiting the gallbladder. Acupuncture is employed to target key acupoints along the shaoyang meridian to restore its regulatory functions, improve spleen and stomach transformation and transportation, facilitate liver and gallbladder qi flow, and promote the circulation of qi and blood. This provides a practical therapeutic approach for acupuncture-based treatment of Crohn's disease.
