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.

Objective Cervical disc herniation(CDH)is one of the common orthopaedic diseases.With the in-depth study of it and the development of cervical implants,the establishment of cervical fusion animal models has become an indispensable part.Notably however,studies of the establishment and evaluation of cervical fusion animal models in China are currently lacking.This study aimed to provide a suitable animal model and evaluation scheme for implants for cervical spine-related research.Methods Small-tailed Han sheep were chosen for anterior cervical discectomy fusion(ACDF)after modified surgery,and a polyetheretherketone(PEEK)interbody fusion cage(Cage)(control group),3D-printed Ti6Al4V Cage(group 1),and new method Ti6Al4V Cage(group 2)were implanted in different cervical segments(C2/3～C4/5)in each sheep,respectively.Hematology and histopathological analyses were carried out after surgery to evaluate recovery of sheep and the biosafety of the materials.Bone in-growth and bone fusion were assessed by X-ray,computed tomography(CT),Micro-CT and quantitative analysis,hard tissue section staining,and biomechanical tests.Results The modified ACDF ovine model was established successfully.There were no significant differences in important hematology indexes(P＞0.05)and histopathological analysis showed no pathological changes,such as inflammatory cell infiltration.The implants had good biosafety.Furthermore,X-ray and CT examinations showed that the position of internal fixation and the interbody fusion were good.Micro-CT and quantitative analysis at 3 and 6 months after operation showed that compared with PEEK Cage group,the bone volume/total volume and trabecular number were significantly increased(P＜0.01)while the trabecular spacing was significantly decreased in the new method Ti6Al4V and 3D-printed Ti6Al4V groups compared with the PEEK Cage group(P＜0.01).Moreover,the new method new method Ti6Al4V Cage group had more bone growth(P＜0.01).Hard tissue section staining demonstrated that the pores of the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage had obvious bone growth and relatively dense pores in the new method Ti6Al4V and 3D-printed Ti6Al4V groups,and the combination was slightly better than that of PEEK Cage.Biomechanical evaluation indicated that the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cage reduced the range of cervical flexion-extension,lateral bending,and axial rotation(P＜0.05)compared with the PEEK cage,as well as enhancing the stability of the cervical vertebra,and the new method Ti6Al4 V Cage was more advantageous(P＜0.05).Conclusions After the establishment of the modified ACDF ovine model,reasonable and effective assessment method were used to demonstrate the suitability and effectiveness of the model and the good biosecurity of all three Cage materials.Compared with the PEEK Cage,the new method Ti6Al4V Cage and 3D-printed Ti6Al4V Cages showed better performances in terms of bone growth and bone fusion,which could enhance the stability of the cervical vertebrae.The new method Ti6Al4V Cage was particularly advantageous.

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.

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.

Intrahepatic cholangiocarcinoma (ICC) is a highly malignant tumor with poor prognosis. In the process of clinical diagnosis and treatment, only a small number of patients can receive surgical treatment in time, and the rest often have local infiltration or distant metastasis at the time of presentation, which can only prolong the overall survival by adjuvant therapy. At present, the main adjuvant treatments in clinical practice include chemotherapy, targeted therapy and immunotherapy. This article reviews the progress of systemic therapy and some clinical trials in patients with advanced unresectable ICC, to provide a reference for the clinical diagnosis and treatment of ICC.

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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective:To investigate the correlation between age and tongue pressure in healthy individuals using a newly-developed tongue pressure measuring device.Methods:A total of 154 healthy volunteers aged 20 to 97 years, without noticeable swallowing difficulties, were selected and divided into seven age groups: 20-29 years ( n=24), 30-39 years ( n=22), 40-49 years ( n=20), 50-59 years ( n=24), 60-69 years ( n=22), 70-79 years ( n=22), and 80 years or more ( n=20). Their maximum, minimum, average and initial pressures, work done, and coefficients of variation were measured using the newly designed tongue pressure measuring device in its intermittent and continuous measurement modes. The tongue pressures were correlated with age and gender. Results:The pressure data obtained using the new device were completely consistent with those from a manometer ( R=1). In the intermittent measurement mode, the readings showed that the maximum, minimum and average tongue pressures decreased significantly with age. In the continuous measurement mode, the initial tongue pressure, average pressure and work done also decreased significantly with age, while the coefficient of variation generally increased with age. There was a negative correlation between age and average tongue pressure ( R2=0.4). The relationship could be expressed as y=-0.8595x+ 103.3 (where x is age, and y is tongue pressure). However, no significant correlation was found between gender and tongue pressure. Conclusions:Tongue pressure and its stability are negatively correlated with age in healthy individuals without swallowing dysfunction, showing no significant correlation with gender.

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.
