低营养及低氧状态下NIH3T3细胞增殖及细胞周期的变化及对bFGF的影响

目的： 体外模拟慢性创面缺氧、低营养环境，观察成纤维细胞在该状态下增殖及细胞周期的变化及对外源性生长因子（bFGF）的反应,探讨低氧、低营养条件下成纤维细胞的病理生理变化。方法: 单纯缺氧环境采用厌氧培养箱，通入混合气，氧分压（PO₂）分为27 mmHg和44 mmHg 2个水平；低营养环境则控制培养液新生牛血清（NCS）浓度。用MTT法检测细胞活性以及其对外源性生长因子的反应，用流式细胞仪检测细胞周期。结果: PO₂ 44 mmHg时细胞增殖速度较同期对照组无明显差异；PO₂ 27 mmHg时，细胞增殖速度较同期对照组明显减慢（P<0.01），细胞被阻滞于G₀期，S期细胞比例明显减少，bFGF未显示促增殖作用。NCS浓度为0.5%的低营养状态下细胞增殖速度较同期对照组明显减慢（P<0.01），细胞被阻滞于G₀-G₁期（P<0.01）；bFGF能明显改善低营养状态下的增殖减慢（P<0.01），使G₂-M期细胞比例增加（P<0.05）。结论: 27 mmHg PO₂或NCS浓度为0.5%的低营养环境使细胞阻滞于G₀-G₁期，影响成纤维细胞增殖；bFGF可以改善低营养条件下细胞增殖减慢的状态，但对极度缺氧条件下的成纤维细胞增殖障碍无明显作用。     

基于复杂网络的《新针灸学》与《经络腧穴学》比较分析研究（英文）

提取《新针灸学》《经络腧穴学》中穴位名称、主治病症信息,基于复杂网络建立穴-症网络,分析两者穴位数量、相互关联程度及主治规律变化,借助拓扑学数据解释变化原因,为传统针灸知识体系的结构化、标准化研究提供具体思路和方法。共纳入《新针灸学》386穴、773种症状、形成152163个穴位配伍对,《经络腧穴学》403穴、253种症状、28755个穴位配伍对。两本教材的穴-症网络存在丰富的差异性,其所载的病症结构化程度随医学知识的更新而提升。《新针灸学》模型具有更加典型的小世界效应,或因其以病症为主要分类手段的优势体现。两本教材穴位定位与主治方面发生许多变化,学科发展、时代背景等方面是变化的主要原因。     

Acupoint stimulation for long COVID: A promising intervention: 穴位刺激治疗长新冠:一种有前景的干预措施

“Long COVID” is a sustained symptom following infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). According to recent statistics, at least 65 million people have long COVID, which poses a long-term threat to human health. The pathogenic mechanisms of coronavirus disease 2019 (COVID-19) are complex and affect multiple organs and systems. Common symptoms include palpitations, breathing difficulties, attention and memory deficits, fatigue, anxiety, and depression. It is difficult to achieve satisfactory treatment effect with a single intervention. Currently, treatment strategies for long COVID are still in the exploratory stage, and there is an urgent need to find appropriate and effective methods for long COVID treatment. Traditional Chinese medicine is effective in treating the various phases of COVID-19. Previous studies have shown that acupoint stimulation therapy is effective in improving palpitations, dyspnea, cognitive impairment, anxiety, depression, and other symptoms in patients. According to previous studies, acupoint stimulation may improve various symptoms related to long COVID. This paper discusses the potential application value of acupoint stimulation in the treatment of long COVID-related symptoms, based on the common sequelae of various systems involved in long COVID, and the effect of acupoint stimulation in the treatment of similar symptoms and diseases in recent years.     

Scientific connotation of “treating different diseases with the same method” from the perspective of metabolic–immune dysregulation in inflammation-mediated carcinogenesis of digestive organs

Inflammation-mediated carcinogenesis develops in the context of chronic inflammation and is a significant cause of cancer within the digestive system. In the chronic inflammation microenvironment, the metabolic activity of tissue cells undergoes extensive changes, which interfere with the normal function of immune cells. Dysregulation of cell metabolism and immune function has been identified as a key factor contributing to inflammation-mediated carcinogenesis within the major digestive organs, such as the stomach, liver, and colorectum. This metabolic–immune imbalance also corresponds to traditional Chinese medicine (TCM) theories of “yin-yang disharmony” and “disharmony between Ying-nutrients and Wei-defense.” The metabolic–immune imbalance has also been regarded as the key factor supporting “treatment of different diseases with the same method,” in which the same approach is adopted in the treatment of different conditions. In the TCM treatment process, it is necessary to first identify TCM patterns and then apply the corresponding TCM to correct the dysregulated metabolic and immune function, thereby blocking the progression from inflammation to malignancy. Our study findings deepen the TCM understanding of metabolic–immune dysregulation and the relationship between metabolic–immune dysregulation, pattern identification, and treatment method. They also provide new insights for the treatment of inflammation-mediated carcinogenesis in major digestive organs and help us further explore the scientific connotation of the TCM strategy of “treating different diseases with the same method.
