As a major global public health concern,the incidence of depression disorder is increasing annually.The pathological mechanism of depression involves bidirectional dysregulation between the hypothalamic-pituitary-adrenal(HPA)and gut-brain axes.According to traditional Chinese medicine(TCM),the liver controls conveyance and dispersion,the spleen governs transportation and transformation,and both jointly maintain the balance between ascending and descending qi movement and zang fu viscera function in the body.Liver qi stagnation and spleen deficiency result in qi movement disorder and a lack of source qi and blood,leading to depression induced by malnutrition of heart spirit.As a classic prescription for soothing the liver,invigorating the spleen,and replenishing blood,Xiaoyao Powder is used to reinforce healthy qi and eliminate pathogenic factors.Xiaoyao Powder not only regulates the"yin in property of liver"but also strengthens the"ascending and descending"of the spleen.As commonly used by ancient and modern physicians,also indirectly inhibits HPA axis upregulation and improves depression-related gastrointestinal dysfunction.This paper systematically expounds the multi-dimensional mechanism of Xiaoyao Powder in treating depression through the two-way regulation of the HPA-gut-brain axis.It reveals the therapeutic characteristics of"multi-component and multi-target"in TCM to provide a novel theoretical basis for the modernization of TCM and the treatment of depression by combining TCM and Western medicine.

Objective:To explore the effects of deep hyperthermia on chemotherapy-related adverse effects and immune-inflammatory indicators in the patients undergoing postoperative adjuvant chemotherapy for colorectal cancer.Methods:This retrospective study included 52 patients who underwent surgery for colorectal cancer at the Affiliated Zhongshan Hospital of Dalian University from September 2021 to December 2023. The patients were divided into two groups based on treatment method: the combination group ( n=29) received postoperative adjuvant chemotherapy combined with deep hyperthermia, while the chemotherapy group ( n=23) received postoperative adjuvant chemotherapy alone. Both groups were treated with the XELOX regimen (oxaliplatin + capecitabine). The degree of bone marrow suppression during treatment was assessed by analyzing peripheral blood parameters, including hemoglobin, leukocyte count, neutrophil count, and platelet count. Immune-inflammatory indicators, including complement, procalcitonin (PCT), interleukin-6 (IL-6), systemic immune-inflammation index (SII), neutrophil-to-lymphocyte ratio (NLR), and platelet-to-lymphocyte ratio (PLR), were compared before and after treatment in both groups to evaluate the effects of deep hyperthermia on the immune-inflammatory response. Chi-square test or Fisher's exact test (two-tailed) was used to compare bone marrow suppression rates, and the immune-inflammatory indicators between the two groups were compared using t-tests or non-parametric tests, depending on whether the data conformed to a normal distribution. Results:In terms of myelosuppression, the incidence rates of moderate to severe decreases in leukocytes, neutrophils, platelets, and hemoglobin in the combination group were 31%, 31%, 21%, and 14%, respectively, compared to 52%, 61%, 48%, and 9% in the chemotherapy group. The change in PCT levels before and after treatment was significantly greater in the combination group than in the chemotherapy group ( P = 0.010). Both the combination group and the chemotherapy group showed significant reductions in SII, NLR and PLR after treatment, and the differences were statistically significant (all P < 0.05). The change in NLR before and after treatment was significantly greater in the combination group than in the chemotherapy group ( P = 0.031). Conclusions:Deep hyperthermia can alleviate chemotherapy-induced adverse effects such as thrombocytopenia and neutropenia in patients undergoing postoperative adjuvant chemotherapy for colorectal cancer. It also appears to improve the inflammatory response in these patients.

Objective:To compare the efficacy of Wnt3a factor and small molecule compound CHIR99021 in culturing colorectal cancer organoid, and to explore the feasibility of replacing Wnt3a with CHIR99021.Methods:The organoids were cultured using 2 culture systems containing Wnt3a or CHIR99021, based on the colorectal cancer cell line HCT116 and rectal cancer tissue from one patient (surgical specimen from the Department of Gastrointestinal Surgery, Zhongshan Hospital Affiliated to Dalian University), including Wnt3a cell organoid, CHIR99021 cell organoid, Wnt3a tissue organoid, and CHIR99021 tissue organoid. The growth of organoids was observed under the optical microscope. The pathological characteristics of organoids and the rectal cancer tissue were analyzed by hematoxylin-eosin (HE) staining and immunohistochemical (IHC) staining, which included cytokeratin(CK) 7, CK20, Ki-67, and stemness marker CD133. The expression of β-catenin (a key Wnt pathway protein) was analyzed by Western blotting (WB) method. The half maximal inhibitory concentration (IC50) values of Wnt3a and CHIR99021 cell organoids were analyzed by drug susceptible test and GraphPad Prism 9.0 software. Independent sample- t test was used for statistical analysis. Results:Under the optical microscope, the size of CHIR99021 cell organoid was relatively uniform, while the size of the Wnt3a cell organoid was uneven, compact and dense spherical structure was formed in both organoids. HE staining showed tumor features including increased nuclear-cytoplasmic ratio and obvious nuclear atypia in the Wnt3a and CHIR99021 cell organoids. The results of IHC staining showed that CK7 was negative, and CK20 and Ki-67 were positive in the Wnt3a and CHIR99021 cell organoids. The results of WB method showed that the relative expression level of β-catenin of the CHIR99021 cell organoid was higher than that of the Wnt3a cell organoid (0.89±0.09 vs. 0.26±0.04), and the difference was statistically significant ( t=13.80, P<0.001). The results of drug susceptible test demonstrated that the IC50 value of the Wnt3a and CHIR99021 cell organoid was 10.91 and 14.55 μmol/L, respectively. Further IHC staining showed that CD133 was positive in the Wnt3a and CHIR99021 cell organoids, with stronger intensity in the CHIR99021 cell organoid. The pathological characteristics of Wnt3a and CHIR99021 tissue organoid were consistent with those of the rectal cancer tissue of the patient, with all CK7 being negative and CK20 and Ki-67 being positive. Conclusions:Both Wnt3a and CHIR99021 can successfully establish colorectal cancer organoids with consistent pathological characteristics. The IC50 value of the CHIR99021 cell organoid is high, which is related to the increased stemness of organoids. The pathological characteristics of Wnt3a and CHIR99021 tissue organoid are consistent with those of the rectal cancer tissue from the patient.

Objective To observe the clinical efficacy of therapy focusing on regulating spleen and stomach for the treatment of acoustic hypersensitivity(AH),which also named as auditory hyperaesthesia,and to explore the relevant factors influencing the efficacy.Methods From January 2018 to December 2023,the patients admitted to the outpatient department of otolaryngology-head and neck surgery of the First Affiliated Hospital of Guangzhou University of Chinese Medicine and diagnosed as AH with complete medical data were included as study subjects.Follow-up through telephone or network was carried out for those patients who with uncertain prognosis.The changes in the pre-and post-treatment scores of Indicators of Acoustic Hypersensitivity Severity(IAHS)were used as the reference index for efficacy evaluation,and the cure rate and effective rate were used as the efficacy analysis indexes for statistical analysis.And then the efficacy of traditional Chinese medicine(TCM)medical care combined with health care focusing on regulating spleen and stomach for the treatment of AH was evaluated.Furthermore,multivariate logistic regression was used to explore the relevant factors influencing the efficacy of AH.Results A total of 298 cases of AH patients meeting the inclusion criteria were collected,among which 151 cases(50.67%)were cured,22 cases(7.38%)were markedly effective,75 cases(25.17%)were effective,and 50 cases(16.78%)were ineffective,with a total effective rate of 83.22%(248/298).The univariate analysis results showed that eight factors(including post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,duration of the disease,presence of tinnitus,presence of hearing drop,presence of vertigo,and age)had an influence on the efficacy,and the differences were statistically significant(P<0.05 or P<0.01).However,the factors of gender,occupation,education level,and history of noise exposure had no influence on the efficacy(P>0.05).The multivariate binary logistic regression analysis showed that five factors,namely post-treatment lifestyle score,range of lifestyle adjustment,severity of AH,presence of vertigo and duration of the disease,had a significant correlation with the cure rate of AH(P<0.05 or P<0.01),and four factors,namely post-treatment lifestyle score,severity of AH,range of lifestyle adjustment and age,had a significant correlation with the effective rate of AH(P<0.05 or P<0.01).Conclusion The method of TCM medical care and health care focusing on regulating spleen and stomach exerts a better efficacy for AH patients.And the lifestyle,severity of AH,duration of the disease,age,and presence of vertigo are the relevant factors affecting the outcomes,which is worthy of further in-depth study.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.
