Objective To explore the traditional Chinese medicine(TCM)syndrome character-istics and medication patterns of cerebral small vessel disease(CSVD)using data mining techniques.Methods Clinical research literature on TCM treatment of CSVD,published from the establishment of the database to September 1,2024,was retrieved from the China National Knowledge Infrastructure(CNKI),Wanfang,and VIP databases.Analyses were conducted on syndromes,drug frequencies,properties,flavors,and meridian tropisms.Data mining was performed using R4.4.1 software to ex-plore associations,correlations,and clustering of TCM herbs,aiming to elucidate medication patterns in CSVD treatment.Results A total of 60 prescription formulas for treating CSVD were screened,involving 142 TCM herbs with a total usage frequency of 1,312 times.The top five most frequently used herbs were Chuanxiong,Danggui,Dilong,Huangqi,and Chishao.Herb properties were pre-dominantly warm and cold;flavors were mainly pungent,bitter,and sweet;and meridian tropisms were primarily to the liver,spleen,and heart meridians.Twenty-nine strong association rules were identified,and association analysis revealed core herbal combinations centered around Chuanxiong,Chishao,and Danggui.Clustering analysis yielded five herbal combinations.Conclusion CSVD is characterized by a deficiency in essence and excess in superficiality.Treatment should focus on tonify-ing deficiencies and eliminating excesses,combining both tonification and purgation methods.Medication patterns predominantly involve herbs for promoting blood circulation and removing blood stasis,often combined with herbs for nourishing the kidney and marrow,calming the liver and suppressing wind,and awakening the mind and opening the orifices.

Objective:Exploratory study on the relationship between TCM syndrome types, TCM constitution and clinical symptoms of idiopathic central precocious puberty children and rapidly progressive early development children in Shanghai, so as to provide a basis for early intervention and syndrome differentiation and treatment.Methods:A cross-sectional study and retrospectively enrolled. Through questionnaire survey, the basic information, clinical symptoms and TCM constitution of children diagnosed with idiopathic central precocious puberty and rapidly progressive early development were collected from the Pediatric Endocrinology Clinic of Affiliated Shuguang Hospital of Shanghai University of Traditional Chinese Medicine from July to August 2022, and the correlation between the distribution, differentiation and clinical symptoms of TCM constitution in children with idiopathic central precocious puberty and children with rapidly progressive precocious puberty in Shanghai were explored through data analysis.Results:① Fast progressive early development children with higher BMI and age than idiopathic central precocious puberty were statistically significant ( P<0.05), and no significant difference in the sex composition ratio between the two groups. ② Among children with idiopathic central precocious puberty and children with rapid progressive early development, the proportion of liver depression fire syndrome was the highest, 59.15% (42/71) and 46.51% (60/129) respectively, and the proportion of Qi depression was the highest, 35.21% (25/71) and 36.43% (47/129) respectively. However, there was no significant difference in the TCM syndrome types and physical distribution of the two groups. ③ The TCM syndrome types of 200 precocious children weres correlated with physical distribution, among which Yin deficiency fire flourishing syndrome was significantly associated with Yin deficiency, liver stagnation fire syndrome was significantly correlated with qi depression, and phlegm dampness obstruction syndrome was significantly correlated with phlegm dampness and Yang deficiency ( P<0.01). ④ A total of 200 children with precocious puberty were more female than male, male BMI was higher than female, and the BMI of children with precocious puberty was higher than other syndrome types, and the differences were statistically significant ( P<0.01). Liver stasis fire syndrome was the highest proportion between boys and girls, but there was no obvious difference in TCM syndrome types between different genders. The highest proportion of breast pain in clinical symptoms was 22.19% (69/311). Conclusion:Children with idiopathic central precocious puberty and rapidly progressive early development children have differences in age and BMI, with no obvious difference in gender composition, TCM syndrome type and physical distribution, but there is a correlation between TCM syndrome type and physical constitution of precocious puberty children.

TCM functional exercises are the important means of TCM to prevent and cure diseases. By adjusting the bones and muscles externally, adjusting the heart and organs internally, promoting blood circulation, improving sleep disorders, enhancing metabolism and immune capacity, the aim of preventing and treating diseases, prolonging life span, and strengthening the body is achieved. TCM exercises have a significant effect on the treatment of various types of fatigue such as chronic fatigue syndrome, Exercise-induced fatigue, post-stroke fatigue, and cancer-related fatigue.

Objective:To discuss the method for establishing the rat models of irritable bowel syndrome(IBS)by chronic water avoidance stress(WAS)method,and to evaluate its feasibility.Methods:Thirty male Wistar rats were randomly divided into control group(n=10)and model group(n=20).The rats in model group were induced by WAS method for 1 h everyday,lasting for 10 consecutive days;the rats in control group underwent no interventions.After modeling,the general conditions and body weights of the rats in two groups were observed and recorded.The elevated plus maze(EPM)test was used to detect the percentages of the number of open arm entries(OE)and the time spent in open arms(OT)of the rats in two groups;the abdominal withdrawal reflex(AWR)test was used to assess the visceral sensitivity of the rats in two groups;electrocardiography was used to detect the heart rate variability(HRV)of the rats in two groups;electromyography(EMG)of the external oblique muscle was used to detect the colorectal pain sensitivity thresholds of the rats in two groups;multi-channel physiological signal recorder was used to monitor the slow wave frequency of the colon of the rats in two groups.Results:There were no death rats in both groups during the modeling period.After modeling,the rats in model group exhibited poor mental status,reduced spontaneous activity,hypoactivity,disordered and dull fur,irritability,and unclean anal areas;whereas,the rats in control group showed no significant changes in the mental state,spontaneous activity,fur,and perianal area.Compared with control group,the body weight of the rats in model group was significantly decreased(P<0.05).The EPM test results showed that compared with control group,the OE percentage and OT percentage of the rats in model group were significantly decreased(P<0.01).The AWR test results showed that 12 rats in model group scored≥3 points,indicating that the successful rate in creating the visceral pain models was 60%.Compared with control group,the low frequency(LF)signals and the ratio of LF/high frequency(HF)of the rats in model group were significantly increased(P<0.01),and the HF was significantly decreased(P<0.05).The EMG results showed that compared with control group,the coloretal pain sensitivity threshold of the colon of the rats in model group was significantly decreased(P<0.01),and the slow wave frequency of the colon was significantly increased(P<0.01).Conclusion:The WAS method for establishing the rat model of IBS effectively demonstrates the changes in behavior and mental state,increased the visceral sensitivity,accelerated colonic slow wave frequency,and autonomic nervous system imbalance;the WAS method can serve as an effective modeling approach for observing and evaluating the related drugs and interventions on treatment of IBS.

TCM believes that spleen deficiency is the root cause of emotional abnormalities in chronic fatigue syndrome (CFS), and clinical treatment often involves the heart, liver and kidney. TCM therapy has a significant efficacy in CFS emotional abnormalities. It is mostly treated with oral administration of TCM, acupuncture, moxibustion and massage therapy. It may play a therapeutic role by improving oxidative stress and immune inflammation, regulating nerve-endocrine, controlling energy metabolism and other ways. It is suggested to establish the syndrome differentiation standard of CFS emotional abnormality in the future, so as to improve the accuracy of syndrome differentiation and treatment; form a perfect treatment guide or expert consensus to guide the standardized application of various internal and external treatment methods; explore objective indicators based on the pathogenesis, and focus on the morphological and functional changes of disease target brain regions with the help of neuroimaging techniques, so as to improve the diagnosis and prognosis evaluation of CFS; based on the guidance of TCM theory, improve the CFS emotional abnormal animal modeling method.

Metabolic heterogeneity plays a central role in sustaining uncontrolled cancer cell proliferation and shaping the tumor microenvironment(TME),which significantly compromises the clinical outcomes and responses to therapy in head and neck squamous cell carcinoma(HNSCC)patients.This highlights the urgent need to delineate the intrinsic heterogeneity and biological roles of metabolic vulnerabilities to advance precision oncology.The metabolic heterogeneity of malignant cells was identified using single-cell RNA sequencing(scRNA-seq)profiles and validated through bulk transcriptomes.Serine-glycine-one-carbon(SGOC)metabolism was screened out to be responsible for the aggressive malignant properties and poor prognosis in HNSCC patients.A 4-SGOC gene prognostic signature,constructed by LASSO-COX regression analysis,demonstrated good predictive performance for overall survival and therapeutic responses.Patients in the low-risk group exhibited greater infiltration of exhausted CD8+T cells,and demonstrated better clinical outcomes after receiving immunotherapy and chemotherapy.Conversely,high-risk patients exhibited characteristics of cold tumors,with enhanced IMPDH1-mediated purine biosynthesis,resulting in poor responses to current therapies.IMPDH1 emerged as a potential therapeutic metabolic target.Treatment with IMPDH inhibitors effectively suppressed HNSCC cell proliferation and metastasis and induced apoptosis in vitro and in vivo by triggering GTP-exhaustion nucleolar stress.Our findings underscore the metabolic vulnerabilities of HNSCC in facilitating accurate patient stratification and individualized precise metabolic-targeted treatment.

Traditional Chinese Medicine (TCM) external therapy for sleep disorder of chronic fatigue syndrome (CFS) has good anti-fatigue effect and can improve sleep quality of patients. The treatment for sleep disorders of CFS with TCM external treatment mainly adopts acupuncture, moxibustion, massage, TCM bath, transcutaneous acupoint electrical stimulation and auricular point sticking, etc., or alone, or comprehensive application, or combined with oral Chinese materia medica. The appropriate treatment method can be selected according to the patients' condition and compliance, which reflects the unique advantages of TCM syndrome differentiation and treatment and the treatment according to people and time. The existing research still needs to further form a standardized and recognized diagnosis and treatment system, so as to better guide clinical popularization and application.
