Colorectal cancer （CRC） is one of the most common cancers， with its incidence ranking high among cancers. It stands as the second leading cause of cancer-related death worldwide. In the early stages， CRC lacks specific symptoms， and most patients are diagnosed at advanced stages， making it a major research focus in the field of gastrointestinal tumors. Currently， clinical CRC treatments face several common challenges， including high surgical risks， frequent metastasis and recurrence， drug resistance， and significant side effects from chemotherapy and radiation therapy. With the development and application of traditional Chinese medicine （TCM）， it has been found that TCM and its active ingredients can effectively inhibit CRC cell proliferation， invasion， migration， and angiogenesis， and promote apoptosis and autophagy， thereby slowing the progression of CRC. This has become a key focus of CRC treatment research. Salvia Miltiorrhiza has multiple pharmacological effects， including activating blood circulation to dispel blood stasis， unlocking meridians to relieve pain， clearing heat to calm irritability， and cooling blood to reduce abscesses. It contains a variety of chemical components， including diterpenoids， phenolic acids， flavonoids， polysaccharides， nitrogen-containing compounds， steroids， and lactone compounds. This review summarized the molecular mechanisms of Salvia miltiorrhiza and its active ingredients in the treatment of CRC. It is found that these ingredients exert anti-CRC effects through various molecular mechanisms， including cell cycle arrest， promotion of apoptosis， inhibition of cell invasion and migration， induction of autophagy， suppression of tumor angiogenesis， and remodeling of the tumor microenvironment. The review aims to provide new insights for the drug development and clinical application of Salvia miltiorrhiza in CRC treatment.

Inflammation is the body’s response to damage， infection or other stimuli， but its excessive or continuous development can lead to a variety of diseases. Although modern medical anti-inflammatory therapies were widely used， it is often accompanied by limitations such as more adverse reactions. Based on the “holistic view” and “differential treatment”， traditional Chinese medicine （TCM） regards inflammation as a manifestation of the imbalance of yin and yang in the body and the conflict between good and evil. The application of anti-inflammatory TCM is not only aimed at the pathological state of “inflammation”， but also based on the overall consideration of “syndrome”. According to different types of syndrome， anti-inflammatory TCM can be divided into heat-clearing and detoxifying agents （such as Lonicera japonica and Isatis indigotica ）， heat-clearing and drying dampness agents （such as Coptidis Rhizoma）， blood-activating and stasis-dissolving agents （such as Salvia miltiorrhiza ） and vital qi-strengthening and pathogenic factor-expelling agents （such as Panax ginseng ）. Four types of anti-inflammatory TCM restore the body’s immune balance through the systematic regulation of multi-component， multi-target and multi-pathway， exhibiting a good anti-inflammatory effect. Future research should focus on integrating systematic biology， applying artificial intelligence， carrying out high-quality evidence-based research， and combining traditional Chinese medicine and Western medicine， so as to reveal the overall regulatory law of anti-inf lammatory effects of TCM and promote clinical rational use.

Parkinson's disease （PD） is a complex neurodegenerative disease involving multiple systems and neurotransmitters. Due to the high clinical heterogeneity of PD，it is urgent to establish a comprehensive and long-term traditional Chinese medicine （TCM） management model. In this paper，the conceptual framework of full-cycle management of PD is preliminarily constructed：based on the evolution of the pathophysiological mechanisms of protein deposition and neurotransmitter disorder in PD，the three-stage syndrome characteristics of the prodromal stage （predominant healthy Qi with subtle pathogenic factors），the early clinical stage （declining healthy Qi with growing pathogenic factors） and the middle and late stages （overwhelming pathogenic factors with deficient healthy Qi） are longitudinally described. Through the syndrome differentiation of visceral manifestations，the etiology and pathogenesis of PD motor and non-motor symptoms were comprehensively analyzed，while the matching treatment methods and prescriptions were inferred，and the modular scheme of the combining main symptoms，accompanying symptoms and secondary symptoms was proposed. The conceptual gap of TCM regarding motor complications （'variable syndrome'） and PD-related hyperpyrexia syndrome （'critical syndrome'） was explained. This framework reflects the characteristics of combination of disease and syndrome and overall constant motion，and provides new theories and research ideas for individualized and whole-process management of PD in TCM.

Objective:To investigate the mutation spectrum of the PIK3CA gene in breast cancer, providing a new basis for the precise treatment of breast cancer with PIK3CA inhibitors.Methods:A retrospective analysis was conducted on 144 breast cancer patients who underwent biopsy before neoadjuvant therapy archived from 2015 to 2020 at the Fourth Hospital of Hebei Medical University. Next-generation sequencing (NGS) was utilized to detect the mutations of 520 genes closely related to the development of solid tumors and targeted therapies. The study compared the differences between reported mutation types and focused on analyzing the mutation status of the PIK3CA gene. The clinical and pathological characteristics, including age of onset, molecular subtypes, and Ki-67, were also analyzed. The correlation between PIK3CA mutations and clinicopathological characteristics was examined using Pearson×s chi-square test and Mann Whitney test. Logistic regression was employed to analyze factors influencing PIK3CA mutations. Kaplan-Meier survival analysis and Cox regression models were constructed using R programming.Results:Among the 144 breast cancer samples, 61 (42.3%, 61/144) exhibited PIK3CA gene mutations, of which 23 cases (53.5%, 23/43) were HER2-positive breast cancer, 28 cases (44.4%, 28/63) were luminal breast cancer, and 10 cases (27.8%, 10/36) were triple-negative breast cancer. Of the detected mutations, three hotspot mutations (H1047R, E545K, and E542K) accounted for 72.1% of the total PIK3CA mutations, with H1047R (52.4%), E545K (16.4%), and E542K (3.3%) most commonly detected. The remaining rare mutations accounted for 26.3%. Co-mutations involving PIK3CA and other genes were also observed in the cohort, occurring with TOP2A and FOXA1, while being mutually exclusive with GATA3 and BRCA2. PIK3CA mutations were significantly associated with HER2 status and were not significantly correlated with the patient′s age, menopausal status, HR status, Ki-67 index, molecular typing, TNM stage or pCR status. Likewise, no significant correlation was found between different PIK3CA mutation status and overall survival.Conclusions:This cohort study shows the overall mutation rate of PIK3CA in breast cancer and the mutation frequencies across different molecular subtypes. The findings reveal a significant correlation between PIK3CA mutations and HER2 status, which provides a new basis for the precise treatment of breast cancer with PIK3CA inhibitors.
