In addition to their role in diverse aspects of protein production, HSPs protect against harmful protein-related stressors. Calycosin exhibits numerous beneficial properties. This study aims to explore the protective effects of calycosin in the heart under heat shock and determine its underlying mechanism. H9c2 cells, western blot, TUNEL staining, flow cytometry, and immunofluorescence staining were used. The time-dependent effects of heat shock analyzed using western blot revealed increased HSP expression for up to 2[Formula: see text]h, followed by protein degradation after 4[Formula: see text]h. Hence, a heat shock damage duration of 4[Formula: see text]h was chosen for subsequent investigations. Calycosin administered post-heat shock demonstrated dose-dependent recovery of cell viability. Under heat shock conditions, calycosin prevented the apoptosis of H9c2 cells by upregulating HSPs, suppressing p-JNK, enhancing Bcl-2 activation, and inhibiting cleaved caspase 3. Calycosin also inhibited Fas/FasL expression and activated cell survival markers (p-PI3K, p-ERK, p-Akt), indicating their cytoprotective properties through PI3K/Akt activation and JNK inhibition. TUNEL staining and flow cytometry confirmed that calycosin reduced apoptosis. Moreover, calycosin reversed the inhibitory effects of quercetin on HSF1 and Hsp70 expression, illustrating its role in enhancing Hsp70 expression through HSF1 activation during heat shock. Immunofluorescence staining demonstrated HSF1 translocation to the nucleus following calycosin treatment, emphasizing its cytoprotective effects. In conclusion, calycosin exhibits pronounced protective effects against heat shock-induced damages by modulating HSP expression and regulating key signaling pathways to promote cell survival in H9c2 cells.</p>","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"1173-1193"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141474131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it has not been internationally recognized for cancer treatment because TCM's anti-tumor mechanism is not fully elucidated, limiting its clinical application and international promotion. This review traced the mechanism of the TCM-mediated tumor cell death pathway and its effect on remodeling the tumor immune microenvironment, its direct impact on the microenvironment, its anti-tumor effect in combination with immunotherapy, and the current status of clinical application of TCM on tumor treatment. TCM can induce tumor cell death in many regulatory cell death (RCD) pathways, including apoptosis, autophagy, pyroptosis, necroptosis, and ferroptosis. In addition, TCM-induced cell death could increase the immune cells' infiltration with an anti-tumor effect in the tumor tissue and elevate the proportion of these cells in the spleen or peripheral blood, enhancing the anti-tumor capacity of the tumor-bearing host. Moreover, TCM can directly affect immune function by increasing the population or activating the sub-type immune cells with an anti-tumor role. It was concluded that TCM could induce a pan-tumor death modality, remodeling the local TIME differently. It can also improve the systemic immune status of tumor-bearing hosts.

While acupuncture-related AEs are generally defined as any undesirable event that occurs in patients during acupuncture treatment that may or may not be associated with the treatment, acupuncture-related adverse reactions (ARs) are defined as any undesirable or harmful reaction induced by trained practitioners practicing acupuncture treatment with standard doses. In this review, we clarify the relationship between AEs and ARs. Furthermore, we compile a list of acupuncture-related AEs reported in systematic reviews and meta-analysis articles. We find that serious acupuncture-related AEs are rare, with serious AEs occurring at a rate of approximately 0.04-0.08 per 10,000 treatments. The most likely serious AEs are pneumothorax, central and peripheral nerve injuries, heart injuries, abdominal organ injuries, infections, and needle breakage. Commonly reported minor AEs include bruising, hematoma, or bleeding at the needling site, as well as vasovagal reactions such as tiredness, dizziness, fainting, or residual pain at insertion points. The analysis identifies contributing factors for serious AEs being deep needle penetration, incorrect acupoint selection, and improper needle manipulation. It also addresses infections caused by contaminated needles, environmental factors, and inadequate skin disinfection. Moreover, other serious AEs, like needle breakage, are mostly due to aggressive manipulation and repeated reheating. Importantly, most acupuncture-related AEs are preventable. To avoid such AEs, acupuncturists in clinical practice should carefully select needling areas, be aware of cautions and contraindications of acupuncture, maintain safe acupuncture depth and hygiene, and strictly adhere to standard operating procedures.</p>","PeriodicalId":94221,"journal":{"name":"The American journal of Chinese medicine","volume":" ","pages":"1555-1587"},"PeriodicalIF":0.0,"publicationDate":"2024-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142515657","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional Chinese Medicine (TCM) has emerged as a promising approach in preventing and treating intestinal fibrosis.

These mechanisms include immune cell balance regulation, suppression of inflammatory responses, reduction of inflammatory mediators, alleviation of colon tissue damage, restoration of intestinal function, modulation of growth factors to inhibit fibroblast activation, dynamic regulation of TIMPs and MMPs to reduce extracellular matrix deposition, inhibition of epithelial-mesenchymal transition and endothelial-mesenchymal transition, autophagy modulation, maintenance of the intestinal mucosal barrier, prevention of tissue damage by harmful factors, and regulation of cell proliferation and apoptosis.
