ObjectiveTo compare the protective effects of water extracts from fresh and dried Dendrobium huoshanense on gastric mucosa in chronic atrophic gastritis (CAG). MethodsMale SD rats (n=72) were randomly divided into 9 groups, with 8 rats in each group, which were normal group, model group, Yangwei Shu (4 g·kg-1) group, low-, medium-, and high-dose fresh D. huoshanense (3.5, 7, and 14 g·kg-1) groups, and low-, medium-, and high-dose dried D. huoshanense (0.7, 1.4, 2.8 g·kg-1) groups. The CAG rat model was successfully established by inducing with N-methyl-N'-nitro-N-nitrosoguanidine (MNNG) and other factors for a total of 11 weeks. Then, the rats were intervened with fresh and dried D. huoshanense for 4 weeks. The serum and gastric tissues of the rats were collected. The changes in gastric juice secretion volume and gastric acid pH value in each group were observed. The gastric mucosal injury was observed by naked eyes and hematoxylin-eosin(HE) staining. The gastric mucus secretion level was determined by Alcian blue and periodic acid-Schiff staining(AB-PAS) staining. The expression levels of tight junction proteins Occludin and ZO-1 in gastric tissues were determined by immunofluorescence. The expression levels of serum pepsinogen Ⅰ (PG Ⅰ), pepsinogen Ⅱ (PG Ⅱ), gastrin 17 (G-17), interleukin-1β (IL-1β), interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA). The expression levels of aquaporin 1 (AQP1), aquaporin 3 (AQP3), and aquaporin 4 (AQP4) in gastric tissues were determined by Western blot. ResultsCompared with the normal group, the model group showed an obviously reduced gastric juice secretion volume (P0.05), significantly increased gastric acid pH value (P0.01), gastric mucosa with obvious atrophy, and a significantly reduced gastric mucus secretion volume (P0.01). The expression of Occludin and ZO-1 in the gastric mucosal barrier was significantly decreased (P0.01). The levels of PG Ⅰ and PG Ⅱ in the serum were obviously decreased (P0.05, P0.01), and the levels of G-17, IL-1β, IL-6, and TNF-α were significantly increased (P0.01). The expression level of AQP1 in the gastric tissue was significantly upregulated (P0.01), and the expression levels of AQP3 and AQP4 were significantly downregulated (P0.01). Compared with the model group, each drug administration group could improve the gastric mucosal atrophy of CAG model rats to varying degrees, obviously increase the gastric juice secretion volume of the model rats (P0.05, P0.01), significantly decrease the gastric acid pH value (P0.01), obviously increase the gastric mucus secretion volume (P0.05, P0.01), obviously decrease the expression levels of G-17, IL-6, IL-1β, and TNF-α (P0.05, P0.01), obviously increase the expression levels of Occludin, ZO-1, PG Ⅰ, and PG Ⅱ (P0.05, P0.01), obviously upregulate the expression levels of AQP3 and AQP4 (P0.05, P0.01), and obviously downregulate the expression level of AQP1 (P0.05, P0.01). ConclusionThe water extracts of fresh and dried D. huoshanense can exert therapeutic effects on CAG by improving gastric mucosal injury, reducing inflammation, and regulating water metabolism. Moreover, the dried D. huoshanense has a better effect.

Cancer is a leading cause of mortality in children and results in a significant disease burden. Lipid metabolic reprogramming emerges as a pivotal cancer hallmark, bearing profound implications for understanding tumorigenesis, developing treatment strategies, and improving prognoses. However, research on lipid metabolism and lipid nutritional interventions related to childhood cancers is notably limited compared to adult cancers. This review focused on the current understanding of fatty acid, cholesterol, and phospholipid metabolism in childhood cancers and discussed the correlation between major lipid dietary patterns (such as high-fat, ketogenic, and Mediterranean diets) and the development and progression of childhood cancers. This review also highlighted existing research gaps on the mechanisms of lipid metabolism and the effects of major lipid dietary patterns, and warranted improved research depth, experimental design, and sample size. Therefore, we advocate for future epidemiological, basic science, and multidisciplinary research in the field of childhood cancers to understand more comprehensively and profoundly the role of lipid nutrition in the prevention and treatment of pediatric cancers.

Objective:To investigate the distribution patterns of TCM syndrome elements and syndrome types in cancer-related fatigue (CRF).Methods:A cross-sectional survey was conducted on tumor patients attending the outpatient clinic and wards of the Department of Oncology, Xiyuan Hospital of China Academy of Chinese Medical Sciences from January to December 2021. Descriptive analysis was used to compare the distribution difference of TCM syndrome elements, symptoms and tongue symptoms of CRF and non-CRF patients. The TCM symptoms of CRF were clustered to summarize the common TCM syndromes of CRF.Results:A total of 306 tumor patients were finally included, of which 229 (75%) were CRF and 77 (25%) were non-CRF. Qi deficiency, blood deficiency, and cold-dampness were the most common deficiency and excess syndrome elements in CRF, and liver deficiency, yin deficiency, and blood stasis syndrome elements occurred more frequently in non-CRF than in CRF. TCM symptoms with a frequency greater than 50% in CRF patients, from high to low, were: fatigue > shortness of breath > insomnia or dreaminess > mental fatigue > forgetfulness>lazy speech > impatience, irritability, depression with sighing. The most frequent tongue symptoms, tongue coating, and pulse symptoms were respectively pale tongue, white and greasy coating or smooth white, and pulse deficiency. The symptoms with greater than 30% frequency in 77 non-CRF patients were, from highest to lowest: impatience and irritability or depression with sighing > insomnia or dreaminess > shortness of breath > dry mouth and throat > lumbar spine pain (excluding traumatic) > numbness of limbs > forgetfulness. The highest-ranked tongue, tongue coating, and pulse symptoms were pale tongue, red tongue or less coating, no coating, and thin pulse, respectively. Through clustering analysis, six common syndromes of CRF were obtained, including qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, and cold dampness and spleen stagnation syndrome.Conclusions:CRF is a common symptom of different types of tumors. Generally, deficiency syndrome is the main symptom. Qi deficiency and blood deficiency are the common syndrome elements. Common symptoms of high frequency and tongue and pulse are fatigue, shortness of breath, mental fatigue, forgetfulness, pale tongue and thin pulse. The common TCM syndrome types can be preliminarily summarized into 6 types: qi and blood deficiency syndrome, heart and liver blood deficiency syndrome, kidney yang deficiency syndrome, qi and yin deficiency syndrome, spleen deficiency and qi stagnation syndrome, cold dampness and spleen stagnation syndrome.

Objective:To explore the compatibility and medication law of Cinnamomi Ramulus-Alismatis Rhizoma medicinal pair in ancient and modern prescriptions.Methods:Ancient prescriptions and Chinese patent medicines containing Cinnamomi Ramulus-Alismatis Rhizoma medicinal pair were retrieved from the database of ancient classic famous prescriptions 1.0 and the database of listed Chinese patent medicines 1.0 developed by the Institute of Information on Traditional Chinese Medicine, China Academy of Chinese Medical Sciences. Excel 2019 was used to establish a database. The ancient and modern medical record cloud platform V2.3.5 and SPSS Modeler 18.0 software were used to perform frequency statistics, association rule analysis, clustering analysis, etc. on the data.Results:Totally 79 ancient articles with Cinnamomi Ramulus-Alismatis Rhizoma medicinal pair were obtained, including 76 ancient prescriptions, involving 250 kinds of Chinese materia medica; 25 kinds of Chinese patent medicine were obtained, involving 186 kinds of Chinese materia medica. The drug properties of ancient prescriptions and modern TCM patent medicines were both mainly warm, cold and neutral. The main tastes of ancient prescriptions and modern Chinese patent medicines were pungent, sweet and bitter. And the drugs mainly belong to spleen, lung, liver and kidney meridians. Correlation analysis suggested the same high-frequency association compatibility of ancient and modern prescriptions, Poria-Cinnamomi Ramulus-Alismatis Rhizoma, Atractylodis Rhizoma-Cinnamomi Ramulus-Alismatis Rhizoma, Atractylodis Macrocephalae Rhizoma-Cinnamomi Ramulus-Alismatis Rhizoma. Both clinical symptoms and diseases associated with medicinal compatibility of ancient prescriptions were intestinal flora, edema and vomiting. The syndrome types included bladder impoundment, dampness trapped in the guardian surface, internal retention of phlegm and morbid fluid. The clinical symptoms associated with medicinal compatibility of modern TCM patent medicine were limb joints pain and edema. The diseases included rheumatic arthritis (RA) and kidney disease. The syndrome types included wind-cold-dampness RA, stagnation of collaterals and kidney yang deficiency. High frequency drug clustering yielded 4 clustered squares.Conclusion:The core indications treated by Cinnamomi Ramulus-Alismatis Rhizoma are exogenous diseases with dampness caused by syndrome types including internal storage of water-dampness, cold-dampness obstruction and so on, which can provide reference for further in-depth research and guidance on clinical medication.

Myocardial fibrosis (MF) is a common pathological manifestation of various heart diseases. Due to the non-renewable nature of myocardial cells, the occurrence of MF represents irreversible damage to the myocardium. Previous studies have suggested that fibroblast-mediated collagen deposition is the main mechanism of MF. Recent studies have found that there is an immune regulation mechanism in the heart itself, and macrophage activation/polarization plays an important role in MF. With the deepening of traditional Chinese medicine research, scholars have found that traditional Chinese medicine can interfere with MF by regulating the renin-angiotensin-aldosterone system (RAAS) system and the inflammatory process, repairing the extracellular matrix, managing oxidative stress, and maintaining the balance of autophagy. This process is closely related to the activation and M1/M2 polarization of macrophages. Throughout the MF process, macrophage activation is beneficial, but excessive activation will be harmful. In the early stage of MF, appropriate M1 macrophage polarization is conducive to activating immunity and removing harmful substances. In the middle and late stages of MF, appropriate M2 macrophage polarization is conducive to remodeling the damaged myocardium. If macrophage activation is excessive/insufficient, or the balance of M1/M2 macrophage polarization is broken, the effect changes from improvement to destruction. Traditional Chinese medicines that regulate the activation/polarization of macrophages have the effects of replenishing Qi and nourishing Yin, as well as regulating Qi and activating blood, but there are also some heat-clearing, dampness-drying, and detoxification products. Therefore, the occurrence of MF may be caused by Qi and Yin deficiency, damp heat accumulation, and Qi stagnation and blood stasis. By summarizing the biological processes involved in macrophage activation/polarization in MF, this paper expounded on the research progress of traditional Chinese medicine in regulating macrophage activation and M1/M2 polarization from different angles to improve MF, so as to provide a reference for the treatment of MF with traditional Chinese medicine.

Receptor-interacting serine/threonine-protein kinase 1 (RIPK1) functions as a key regulator in inflammation and cell death and is involved in mediating a variety of inflammatory or degenerative diseases. A number of allosteric RIPK1 inhibitors (RIPK1i) have been developed, and some of them have already advanced into clinical evaluation. Recently, selective RIPK1i that interact with both the allosteric pocket and the ATP-binding site of RIPK1 have started to emerge. Here, we report the rational development of a new series of type-II RIPK1i based on the rediscovery of a reported but mechanistically atypical RIPK3i. We also describe the structure-guided lead optimization of a potent, selective, and orally bioavailable RIPK1i, 62, which exhibits extraordinary efficacies in mouse models of acute or chronic inflammatory diseases. Collectively, 62 provides a useful tool for evaluating RIPK1 in animal disease models and a promising lead for further drug development.
