In view of the difficulties and blind spots of western medicine, how to make scientific decisions to standardize the treatment of breast cancer in traditional Chinese medicine and improve the participation of traditional Chinese medicine in the treatment of breast cancer is an important focus of innovative breakthroughs in breast cancer treatment. Based on the clinical experience of Professor LIN Yi, a master of traditional Chinese medicine, and on the basis of "disease identification and syndrome differentiation", this paper summarizes and refines the status of qi and blood imbalance, accumulation of phlegm and blood stasis, viscera deficiency, and cold heat cementation in breast cancer, and further proposes the "six views" of breast cancer balanced treatment: the pathogenesis view focuses on "evil invasion due to vital qi deficiency, and the proliferation of tumors", and the pathogenesis view focuses on "cancer toxin and imbalance of yin and yang", the diagnostic view focuses on "examining the underlying factors and understanding the causes and effects", the differentiation view focuses on "balancing qi, blood, yin, and yang to achieve harmony", the therapeutic view focuses on "supporting vital qi and eliminating evil, and considering the root cause and syndromes", and the rehabilitation view focuses on "adjusting balance to maintain a stable state". We are committed to holistic syndrome differentiation and treatment, balancing yin, yang, qi, and blood, thereby harmonizing the internal environment of the human body, and mobilizing the immune and rehabilitation functions of the body.

Traditional Chinese medicine(TCM)is a medical science about the physiological state and disease process of human body.It contains the universality of general thinking methods and the particularity of oriental cultural thinking.Starting from the necessity of the construction of clinical thinking mode of TCM and based on the philosophical features of TCM,this paper re-examines and analyzes the importance of the thinking mode for the nature of disease,and puts forward the six-dimensional differentiation system for TCM clinical practice,which covers disease differentiation,syndrome differentiation,symptom differentiation,pathogenesis differentiation,constitution differentiation and qi differentiation.Guided by the thinking mode of six-dimensional differentiation system,the TCM clinical practice exerts holistic view:disease differentiation is advocated to combine syndrome differentiation;symptom differentiation is mainly for the primary symptoms,which can clarify the transformation of pathogenesis,the progression of the disease,and the evolution of the syndromes;pathogenesis differentiation focuses on the evolution of pathogenesis,and treatment based on syndrome differentiation and modification of drugs based on symptoms are required;constitution differentiation should be made on the basis of the patient's constitution,and detailed identification of the etiology,disease location,disease nature,and progression of the disease should also be conducted;qi differentiation should be made on the basis of the comprehensive consideration of the exuberance and decline of healthy qi and pathogenic qi,thus to ensure the treatment adapting to the individuality,climate,and environment.The establishment of six-dimensional differentiation system aims to expound the internal mechanism of key points for disease differentiation,therapeutics based on syndrome differentiation,drug modification according to symptom differentiation,and differentiation of pathogenesis and illness state,which is helpful to the overall grasp of the disease,pathogenesis,syndrome and treatment in clinical practice,and will provide theoretical basis for the precise treatment of disease.

Stress is a non-specific adaptive response of organisms to internal and external stimuli,which helps maintain the homeostasis of the body's internal environment.However,when the stress response exceeds the body's adaptation threshold,a variety of diseases will be induced.The morbidity and mortality of breast cancer rank the highest among female malignant tumors.Professor LIN Yi,the first master of traditional Chinese medicine(TCM)in the field of breast diseases who founded the theory of'treating breast diseases from the perspective of six stagnations',believes that six stagnations are the core pathogenesis of breast cancer,and six stagnations are closely related to the body's stress response system.TCM has unique advantages in adjusting the balance of stress homeostasis.By reviewing the classical TCM theory,the theory of'treating breast diseases from the perspective of six depressions'and the modern stress theory,this paper put forward the theory of'stress-based breast cancer prevention & treatment',and expounded the pathogenesis features,pathogenic characteristics and molecular mechanism of stress factors in mediating the development and progression of breast cancer.Moreover,the core idea and treatment principle based on the regulation of stress homeostasis were proposed,and the prescription and medication guided by the theory of'stress-based breast cancer prevention & treatment'were summarized.The establishment of the theory of'stress-based breast cancer prevention & treatment'enriches the theoretical system of breast cancer in TCM,and is expected to provide a new approach for improving the clinical prognosis of breast cancer patients.

Objective:To assess the efficacy of parent training (PT) on attention deficit hyperactivity disorder (ADHD) symptoms, behavioral problems, and parenting stress in child with ADHD or ADHD symptoms.Methods:Randomized controlled trials of the effect of PT on ADHD symptoms in Chinese children with ADHD or ADHD symptoms were collected by PsychINFO, PubMed, EMBASE, Web of science, Scopus, China National Knowledge database, WanFang database, the China Science and Technology Journal Database and the China Biology Medicine disc. The quality of the included studies was evaluated by version 2 of the Cochrane tool for assessing risk of bias in randomized trial. Forest plots were drawn using Review Manager 5.4.1, sensitivity analyses of results were performed using Stata 18.0 to assess the stability of the results, and publication bias was assessed using funnel plots and Egger's test.Results:A total of 10 studies containing 571 subjects in the experimental group and 562 subjects in the control group met the inclusion exclusion criteria. Significant differences were observed in various measures, including overall ADHD symptoms (MD=-2.43, 95% CI: -3.95--0.91), inattention (MD=-1.10, 95% CI: -1.94--0.26), hyperactivity/impulsivity (SMD=-0.58, 95% CI: -0.87--0.28), overall conduct problems (SMD=-0.80, 95% CI: -1.05--0.55), conduct problem (SMD=-1.34, 95% CI: -2.31--0.37), learning problem (SMD=-0.81, 95% CI: -1.40--0.23), impulsivity/hyperactivity (SMD=-0.53, 95% CI: -0.78--0.29), hyperactivity index (SMD=-1.27, 95% CI: -1.99--0.55), parenting stress index (SMD=-0.69, 95% CI: -1.12--0.26), difficult child (MD=-1.96, 95% CI: -3.44--0.48), dysfunctional interaction (MD=-3.10, 95% CI: -4.43--1.78), and parenting distress (MD=-3.35, 95% CI: -4.59--2.12)(all P<0.05). However, no significant differences were observed in oppositional-defiant disorder, anxiety, or somatic problem. Conclusions:The initial findings suggested that PT was effective for Chinese children with ADHD or ADHD symptoms.The addition of PT appeared to improve core symptoms of ADHD (inattention and hyperactivity/impulsivity), conduct problems, and parental stress more effectively than routine care alone.

OBJECTIVE: To carry out genetic testing for a patient with 45,X/46,XY mosaicism and autism spectrum disorder (ASD). METHODS: Peripheral blood samples of the patient and his parents were collected for the extraction of genomic DNA. Trio-based whole exome sequencing and Sanger sequencing were carried out thereafter. RESULTS: The proband and his father were found to harbor a heterozygous c.4781G>A (p.Arg1594Gln) variant of the CACNA1I gene. In addition, the proband was also found to harbor a de novo c.268C>T (p.Arg90Trp) missense variant of the MTRR gene. Based on guidelines of the American College of Medical Genetics and Genomics (ACMG), the c.4781G>A (p.Arg1594Gln) variant of the CACNA1I gene was predicted to be pathogenic (PVS1, PM1, PM2, PP3), while the c.268C>T (p.Arg90Trp) variant of the MTRR gene was predicted to be of uncertain significance. CONCLUSION Variants of the CACNA1I and MTRR genes, together with the chromosomal mosaicism, may have predisposed to the susceptibility to the ASD in this patient.

OBJECTIVE: To analyze the pathogenic variants of the KIF1A gene and its corresponding protein structure in an autism spectrum disorder (ASD) family trio carrying harmful missense variants in the KIF1A gene. METHODS: The peripheral blood DNA of the patient and his parents was extracted and sequenced using whole exome sequencing (WES) technology and verified by Sanger sequencing. Bioinformatics software SIFT, PolyPhen-2, Mutation Taster, and CADD software were used to analyze the harmfulness and conservation of variants. The Human Brain Transcriptome (HBT) database was used to analyze the expression of the KIF1A gene in the brain. PredictProtein and SWISS-MODEL were further used to predict the secondary structure and tertiary structure of KIF1A wild-type protein and variant protein. PyMOL V2.4 was utilized to investigate the change of hydrogen bond connection after protein variant. RESULTS: The WES sequencing revealed a missense variant c.664A>C (p.Asn222His) in the child's KIF1A gene, and this variant was a de novo variant. The harmfulness prediction results suggest that this variant is harmful. By analyzing expression level of KIF1A gene in the brain. It is found that KIF1A gene widely expressed in various brain regions during embryonic development. By analyzing the variant protein structure, the missense variant of KIF1A will cause many changes in the secondary structure of protein, such as alpha-helix, beta-strand, and protein binding domain. The connection of hydrogen bond and spatial structure will also change, thereby changing the original biological function. CONCLUSION The KIF1A gene may be a risk gene for ASD.
