Pathological mood changes,mainly depression,occurring during the diagnosis and treatment of breast cancer are referred to as breast cancer-related depression(BCRD).Numerous epidemiological and clinical studies have confirmed that BCRD is a complex condition that is difficult to treat and has a poor prognosis.Most existing clinical treatments involve the use of postoperative chemotherapy for breast cancer,and antidepressant drugs,which treat breast cancer and depression as two independent diseases and have various disadvantages such as low efficiency and strong adverse reactions.Traditional Chinese Medicine(TCM)has a unique value in the prevention and treatment of BCRD via its ability to regulate multiple pathways and targets using multiple components at the same time.In this paper,we review the mechanism of BRCD and the therapeutic mechanisms of TCM from the aspects of neurological disorders,inflammatory immune response,and intestinal flora disorders,with a view to providing references for the clinical application and research of TCM in the treatment of BCRD.

Exosomes represent a class of nanoscale extracellular vesicles that facilitate the exchange of genetic information among various cells.Alzheimer's disease(AD)stands as a progressive neurodegenerative disorder characterized by its subtle and advan-cing onset,representing the foremost form of dementia lacking effective therapeutic interventions.Notably,investigations have illuminated the involvement of exosomes in the pathogenesis of AD,attributing diagnostic and therapeutic significance to their role,particularly concerning exosomal microRNAs(miRNA).The miRNAs carried by exosomes serve as potential biomarkers for AD,while also exhibiting potential benefits in ameliorating cognitive dysfunction in individuals afflicted by AD.This article aims to comprehensively review the origins of exosomes(encom-passing both mesenchymal cell-derived exosomes and brain-de-rived exosomes)and their potential as therapeutic agents targe-ting AD.

Objective To investigate the progression of breast cancer in mice induced by chronic binding stress and the regulatory mechanism of Xiaoyao SAN based on TGF-β1/CD147 signal pathway.Methods 40 BABL/c mice were randomly divided into tumor group,model group,Xiaoyaosan group and Mifepristone group,and then 4T1 cell line was inoculated into the armpits of each group of mice.After Tumor formation,mice in all groups except tumor group were subjected to chronic restraint stress for 21 days.Meanwhile,mice in Xiaoyaosan and Mifepristone groups were gavaged with the corresponding drugs,and mice in the other two groups were gavaged with normal saline.After the modeling,the mice were sacrificed after anaesthesia.The weight and volume of the tumors and visceral index of the mice were measured.The contents of serum tumor markers(CA199,CEA,VEGF),serum neurotransmitters(DA and CORT),and inflammatory mediators(TGF-β1 and IL-10)in tumor tissues were detected by Elisa.The expressions of iNOS and Arg-1,the polarization markers of macrophages,and the expressions of CD147 and its downstream signaling molecules MMP2,MMP9 and VEGF in tumor tissues were all detected by immunohistochemistry and Western blot.Results Compared with tumor group,in model group,tumor weight and volume,serum CA199,CEA,VEGF,CORT content,tumor TGF-β1 and IL-10 content were significantly increased;visceral index and serum DA content were significantly reduced;the expression of M2-type polarization marker Arg-1 in tumor macrophages was significantly increased,while the expression of M1-type polarization marker iNOS was significantly decreased;the expressions of CD147 and its downstream signaling molecules MMP2,MMP9 and VEGF were significantly increased.Both Xiaoyaosan and mifepristone could effectively reverse the above changes.Conclusion The mechanism of chronic restraint stress promoting breast cancer progression in mice is related to the increased release of TGF-β1 from M2-type polarization of tumor-associated macrophages,which activates CD147 and its downstream related signals.Xiaoyaosan could relieve the M2-type polarization of macrophages caused by increased corticosterone under stress conditions,reduce the production of TGF-β1,inhibit CD147 and its downstream signal,and thus inhibit the progression of breast cancer caused by chronic restraint stress in mice.

Purpose::To identify the risk factors for training-related lower extremity muscle injuries in young males by a non-invasive method of body composition analysis.Methods::A total of 282 healthy young male volunteers aged 18 -20 years participated in this cohort study. Injury location, degree, and injury rate were adjusted by a questionnaire based on the overuse injury assessment methods used in epidemiological studies of sports injuries. The occurrence of training injuries is monitored and diagnosed by physicians and treated accordingly. The body composition was measured using the BodyStat QuadScan 4000 multifrequency Bio-impedance system at 5, 50, 100 and 200 kHz to obtain 4 impedance values. The Shapiro-Wilk test was used to check whether the data conformed to a normal distribution. Data of normal distribution were shown as mean ± SD and analyzed by t-test, while those of non-normal distribution were shown as median (Q 1, Q 3) and analyzed by Wilcoxon rank sum test. The receiver operator characteristic curve and logistic regression analysis were performed to investigate risk factors for developing training-related lower extremity injuries and accuracy. Results::Among the 282 subjects, 78 (27.7%) developed training injuries. Lower extremity training injuries revealed the highest incidence, accounting for 23.4% (66 cases). These patients showed higher percentages of lean body mass ( p = 0.001), total body water (TBW, p=0.006), extracellular water ( p=0.020) and intracellular water ( p=0.010) as well as a larger ratio of basal metabolic rate/total weight ( p=0.006), compared with those without lower extremity muscle injuries. On the contrary, the percentage of body fat ( p=0.001) and body fat mass index ( p=0.002) were lower. Logistic regression analysis showed that TBW percentage > 65.35% ( p=0.050, odds ratio =3.114) and 3rd space water > 0.95% ( p=0.045, odds ratio =2.342) were independent risk factors for lower extremity muscle injuries. Conclusion::TBW percentage and 3rd space water measured with bio-impedance method are potential risk factors for predicting the incidence of lower extremity muscle injuries in young males following training.
