Breast cancer prevention and treatment have become major issues that urgently need to be addressed in the field of global public health. As a key pathological transitional stage in the progression of breast cancer， preneoplastic breast cancer （PBC） carries a significant risk of clinical transformation. Effective intervention in the progression of PBC is of great clinical significance in preventing the occurrence of breast cancer. Pathological studies have shown that abnormal angiogenesis is a key mechanism driving the transformation of PBC into breast cancer. Vascular endothelial growth factor （VEGF）， as a core regulatory molecule that promotes angiogenesis， plays a pivotal role in this process. The malignant transformation of PBC is closely associated with the abnormal activation of the VEGF-mediated pro-angiogenic network. Although modern medicine has achieved certain therapeutic effects through surgery and endocrine therapy， clinical limitations such as invasiveness， drug resistance， and adverse reactions still exist. Recent studies have demonstrated that the VEGF signaling system mediates the phosphatidylinositol 3-kinase-protein kinase B （PI3K/Akt） signaling pathway and the mitogen-activated protein kinase （MAPK） pathway. In addition， the hypoxia-inducible factor-1α （HIF-1α）/VEGF signaling pathway and the delta-like ligand 4 （DLL4）/Notch receptor 1 （Notch1） signaling pathway， together with other pathways， form a complex regulatory network that plays a central role in angiogenesis during PBC. Traditional Chinese medicine （TCM）， characterized by multi-component synergy， multi-pathway regulation， and high safety， demonstrates significant advantages in inhibiting pathological angiogenesis and blocking PBC progression by targeting the VEGF signaling pathway. From the perspective of VEGF pathway regulation， this paper systematically reviews the latest research progress on TCM in inhibiting angiogenesis and intervening in PBC， and discusses its mechanisms and application value in the early prevention and treatment of PBC， with the aim of providing references for optimizing clinical intervention strategies for PBC.

Medical therapy and surgical intervention are the two primary approaches for treating myocardial bridge.However,there remains controversy regarding the use of coronary artery bypass grafting(CABG)and myocardial bridge unroofing.Here,we report a case of myocardial infarction following CABG in a patient with a myocardial bridge.The patient was admitted to Lanzhou First Peopie's Hospital with persistent chest pain,chest tightness,and shortness of breath lasting 2 hours.Physical examination revealed no significant abnormalities.Electrocardiography(ECG)indicated extensive anterior wall myocardial infarction.Laboratory findings showed myoglobin levels of 140.1 ng/ml and troponin Ⅰ levels of 2.59 ng/ml,with no other significant abnormalities.The initial diagnosis was acute extensive anterior wall myocardial infarction.Emergency coronary angiography revealed a myocardial bridge in the mid-segment of the left anterior descending artery(LAD).Emergency CABG using the left internal mammary artery to the LAD was performed,leading to symptomatic improvement,and the patient was discharged in stable condition.However,the patient experienced a recurrent myocardial infarction seven years post-surgery and received secondary preventive medical therapy.The patient is currently under ongoing follow-up care.CABG is an effective treatment for myocardial bridge.However,based on the case reported in this study,we recommend careful evaluation of whether a patient may benefit from CABG.

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

Objective To observe the clinical efficacy of traditional Chinese medicine(TCM)sequential therapy in treating patients with psoriasis vulgaris in Shenzhen,and to explore the syndrome differentiation and treatment for the patients with psoriasis vulgaris in Shenzhen region.Methods From January 2019 to February 2024,70 cases of psoriasis vulgaris admitted to Shenzhen Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Shenzhen Bao'an Traditional Chinese Medicine Hospital Group)were retrospectively analyzed.The patients were divided into the observation group(39 cases)and the control group(31 cases)according to the treatment plans.In the control group,only topical application of Calcipotriol Ointment was given throughout the treatment,while in the observation group the patients were treated with TCM sequential therapy according to the illness stage on the basis of treatment for the control group,i.e.,internal administration of modified Shuiniujiao Huanglian Decoction was given in the acute stage and modified Sijunzi Shuiniujiao Decoction was given in the remission stage.Both groups were treated for 3 months.Before and after the treatment,the changes of Psoriasis Area and Severity Index(PASI)scores,Dermatology Life Quality Index(DLQI)scores and TCM syndrome scores in the two groups were observed.After treatment,the clinical efficacy and drug safety of the two groups were evaluated.Results(1)After 3 months of treatment,the total effective rate of the observation group was 89.74%(35/39),and that of the control group was 74.19%(23/31).The intergroup comparison(tested by chi-square test)showed that the efficacy of the observation group was significantly superior to that of the control group(P＜0.05).(2)After treatment,the PASI scores for evaluating the severity of skin lesions in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(3)After treatment,the DLQI scores for evaluating the quality of life in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(4)After treatment,the scores of TCM syndromes such as erythema,itching,vexation and dry mouth in the two groups were significantly decreased compared with those before treatment(P＜0.05),and the decrease in the observation group was significantly superior to that in the control group(P＜0.05).(5)During the treatment period,no obvious adverse reactions occurred in the two groups of patients,with high safety.Conclusion On the basis of conventional western medicine treatment,application of TCM sequential therapy exerts certain clinical efficacy in treating patients with psoriasis vulgaris in Shenzhen region,and the combined therapy is effective on controlling the patients'illness conditions,significantly alleviating the symptoms and improving the quality of life of the patients.

Fresh Chinese herbal medicine,being distinct from the dried herbs,is one of the therapies of traditional Chinese medicine(TCM)widely used in dermatology.It is employed to treat various skin diseases,namely herpes simplex,herpes zoster,common warts,flat warts,boils,carbuncles,erysipelas,acne vulgaris,fungal skin diseases,psoriasis,contact dermatitis,insect bite dermatitis,and eczema.The commonly-used fresh herbs for skin diseases are fresh Portulacae Herba,fresh Houttuyniae Herba,fresh Rubiae Radix,fresh Lygodii Spora,fresh Patriniae Herba,fresh Aloe,fresh Plataginis Herba,fresh Pinelliae Rhizoma,and fresh Taraxaci Herba.These herbs usually have the actions of clearing heat,detoxifying,and cooling blood.For the treatment of skin diseases,fresh herbal medicine can be administered orally or applied topically,with a predominant use of topical application or a combination of oral and topical administration.Due to the rapid development of modern society,the supply and standardization of fresh herbs fail in meeting the demands of a large population of the patients,leading to their gradual decline in use.However,the efficacy of fresh herbs cannot be entirely replaced by that of the dried herbs.This article reviewed the advances in the modern application of fresh Chinese herbal medicine in dermatology,aiming to promote further research and expand its clinical application in treating skin diseases.

Objective:To develop an essential version of the Sleep Disorder ICF combination with assessment efficacy based on item response theory(IRT),and provide a basis for the connection between assessment and treat-ment.Method:Based on the sampling principle of the maximum variation strategy,convenience samples were col-lected.The control variables of maximum variation included age,body mass index(BMI),the physical com-ponent summary(PCS)and mental component summary(MCS)of SF-12,the Pittsburgh Sleep Quality Index(PSQI),and the Symptom Checklist 90(SCL-90).ICF core set of sleep disorders,Pittsburgh Sleep Quality Index(PSQI),Montreal Cognitive Assessment(MOCA),Symptom Checklist-90(SCL-90),and the 12-item Short Form Health Survey(SF-12)were administered to eligible participants.An abridged version of the ICF-based comprehensive core set was conducted for sleep disorders using IRT.Monte Carlo simulation was ap-plied to analyze the relationship between individual functional levels(θ)and item difficulty in person-item maps,and to calculate the degree of benefit from interventions.Result:A 3-parameter logistic model(3PLM)with 34 categories was developed,demonstrating high reliability(internal consistency reliability test results:Cronbach's α=0.9249,Guttman's λ-2=0.9320,MS statistic=0.9398,LCRC=0.9585)and validity(the scores of the 34 ICF categories were significantly correlated with the original ICF scores,PSQI scores,SCL-90 scores,and SF-12 scores,P<0.001).The person-item map was used to match individual sleep-related functional levels(θ)to the item difficulties,distinguishing between the mastered and challenging categories,The degree of benefit was calculated for each matched item,revealing a strong cor-relation between item difficulty and benefit degree(P<0.001,Pearson correlation coefficient was 0.777).Conclusion:This study constructed a parsimonious version of the ICF-based comprehensive core set for sleep disorders with 34 items using IRT.The model can effectively evaluate the sleep-related(including cognitive-be-havioral,psychological-emotional,and social)functional levels in individuals with sleep disorders.The applica-tion of the model analysis further provides a visual tool and the expected benefit after intervention items,which can offer new insights for the rehabilitation of sleep disorders.

Objective:To explore the effectiveness of outcome-oriented TECK teaching in the standardized training of neurology resident physicians, and to evaluate its impact on clinical practice, clinical thinking, and self-learning abilities.Methods:A controlled study design was adopted, and 78 resident physicians who rotated through the Department of Neurology at Guangdong Provincial People's Hospital Affiliated to Southern Medical University between November 2022 and November 2024 were divided into a control group ( n=39) and an experimental group ( n=39) according to their admission order. The control group received the traditional "theoretical teaching, rotation training, exit assessment" mode. The experimental group received an outcome-oriented TECK teaching mode, which included four modules: theoretical class, experimental course/practice, case discussion, and knowledge reinforcement. The two groups of residents were evaluated for clinical practice ability, clinical thinking ability, and teaching satisfaction. SPSS 22.0 was used for t-test and chi-square test. Results:The experimental group outperformed the control group in all dimensions of clinical practice ability (except for doctor-patient communication ability) (all P<0.001), such as basic operational skills [(4.42±0.41) vs. (3.87±0.56)] and emergency management ability [(4.38±0.39) vs. (3.65±0.62)]. The clinical thinking ability scores of the experimental group were higher (all P<0.001), such as diagnostic logic [(4.43±0.38) vs. (3.92±0.51)] and decision-making basis [(4.45±0.42) vs. (3.78±0.63)]. In terms of self-learning ability, the experimental group showed significant improvements in literature search [(4.42±0.43) vs. (3.65±0.58)] and knowledge update [(4.38±0.39) vs. (3.42±0.61)] (both P<0.001). In terms of teaching satisfaction, the experimental group scored higher in dimensions such as course design [(4.42±0.41) vs. (3.89±0.58)] and clinical fit [(4.45±0.37) vs. (3.82±0.61)] (all P<0.001). Conclusions:The outcome-oriented TECK teaching mode can effectively enhance the clinical practice and thinking abilities of neurology residents in standardized training, and improve the effectiveness of self-learning, providing an innovative path for the training of specialized physicians. In the future, interdisciplinary integration and long-term tracking and evaluation need to be optimized.
