Objective:To investigate the anti-fatigue effect of Dendrobium and Panax Quinquefolius Granules(DPQG)on the overtrained mice,and to clarify its possible mechanism.Methods:A total of 48 mice were randomly divided into control group(equal volume of distilled water),low dose of DPQG group(400 mg·kg-1 DPQG),medium dose of DPQG group(800 mg·kg-1 DPQG),and high dose of DPQG group(1 600 mg·kg-1 DPQG).The DPQG were administered by gavage for 35 d,and the rotarod test and swimming endurance test were performed 30 min after last administration.Serum,liver tissue,and muscle tissue were collected from the mice in various groups.ELISA method was used to detect the serum lacticacid(LAC)levels and lactate dehydrogenase(LDH)activities,and the malondialdehyde(MDA)levels,superoxide dismutase(SOD)and glutathione peroxidase(GSH-Px)activities,and the liver glycogen and muscle glycogen levels in muscle tissue of the mice in various groups;HE staining was used to observe the pathomorphology of muscle tissue of the mice.Transcriptomics and metabolomics technologies were used to identify the key genes and metabolites in muscle tissue of the mice in control group and high dose of DPQG group and to analyze the correlations between differentially expressed genes(DEGs)and differentially expressed metabolites.Results:Compared with control group,the rod turning exhaustion time of the mice in different doses of DPQG groups were significantly increased(P＜0.05),and the swimming exhaution time of the mice in high dose of DPQG group was increased(P＜0.05).Compared with control group,the LDH,SOD,and GSH-Px activities of the mice in medium and high doses of DPQG groups were increased(P＜0.01).Compared with control group,the levels of MDA and liver glycogen of the mice in medium and high doses of DPQG groups were decreased(P＜0.05 or P＜0.01).The transcriptomics sequencing results showed that DPQG mainly acted on DEGs such as Trib3 and Olfr495;the Gene Ontology(GO)functional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG)signaling pathway enrichment analysis results showed that the DEGs were mainly enriched in olfactory-related processes and signaling pathways;the metabolomics KEGG analysis results showed that the differential metabolites were mainly enriched in the regulation pathway of inflammatory mediators on tryptophan(TRP);the combined analysis of transcriptomics and metabolomics results showed that the piezo1 gene had high correlations with the differential metabolites β1-solamarine(r=-1,P＜0.05)and tilidine(r=1,P＜0.05).Conclusion:DPQG can exert an anti-fatigue effect on the overtrained mice by modulating LAC metabolism and glycogen homeostasis,as well as maintaining the oxidative/antioxidant balance in the body;its anti-fatigue mechanism is related to the Olfr495 and piezo1 genes and the regulation pathway of inflammatory mediators on TRP channels.

Aortic regurgitation and mitral regurgitation are more common in elderly heart valve disease,and both may be present in some patients.Severe aortic regurgitation complicated with severe mitral regurgitation often requires surgical valve replacement,but in patients at high risk of surgery,the risk of perioperative mortality is significantly increased.Therefore,for such patients,minimally invasive interventions can significantly improve long-term patient outcomes while reducing surgical risk.This article report a case of transcatheter aortic valve replacement combined with transcatheter edge-to-edge repair in the treatment of severe aortic regurgitation combined with mitral valve prolapse,in order to explore new treatment ideas for similar cases.

This article systematically summarized the clinical experience of Professor Han Mingxiang,a national TCM master,in treating chronic obstructive pulmonary disease(COPD)from the perspective of the"qi monism"theory,proposing an innovative"three stages,three strategies"diagnostic and treatment approach.Under the guidance of"qi monism",Professor Han believes that the core pathological mechanisms of COPD progress are through three successive stages:dysfunction in the ascent and descent of qi,deficiency of yang qi,and prolapse of the great qi,all of which stem from the disruption of the dynamic balance of qi.In response to this chain of qi imbalance,Professor Han develops three strategies:"strengthening the foundation","illuminating the central yang",and"lifting and correcting",which aim to regulate qi flow,support yang qi,and coordinate the three energizers in a phased manner.This approach seeks to achieve dynamic restoration and holistic balance of qi,with prescriptions carefully aligned with the dynamic balance and pathological changes of qi,yielding distinctive therapeutic effects.

Menstrual migraine is a specific subtype of migraine unique to women,closely related to the menstrual cycle,characterized by periodic and intractable headaches,often accompanied by nausea,vomiting or photophobia and phonophobia,which seriously affects life and has a high degree of disability.Its pathogenesis is complex,involving multi-dimensional regulation such as estrogen fluctuations,neurovascular responses and genetic and environmental factors,but the specific mechanism has not been fully clarified.In recent years,with the increasing social attention to women's health,the clinical research demand for menstrual migraine has become increasingly urgent.Currently,modern medicine can alleviate symptoms through acute drug intervention(such as non-steroidal anti-inflammatory drugs,triptans)and preventive treatment(such as beta-blockers,CGRP antagonists),but there are problems such as drug dependence and insufficient individualization.Traditional Chinese medicine,based on the"holistic concept"and"syndrome differentiation and treatment"theory,regulates the balance of qi,blood,yin and yang through therapies such as traditional Chinese medicine and acupuncture,showing unique advantages in improving symptoms and preventing recurrence.The combination of traditional Chinese and Western medicine can optimize the therapeutic effect and reduce side effects through synergistic effects,but the full-cycle prevention and treatment strategy still needs further exploration.This article systematically reviews the pathogenesis and research progress of treatment of menstrual migraine in traditional Chinese and Western medicine,emphasizes the interaction between hormone fluctuations and neurovascular responses,and proposes an individualized intervention plan based on the menstrual cycle,providing new ideas for clinical practice and reference directions for future research.

Objective:To analyze and validate the reliability and validity of the social skills improvement system-rating scales Chinese version (parent version) (SSIS-RS-C) in middle school students.Method:A total of 1 486 parents of middle school students were recruited according to the cluster sampling method.The social responsiveness scale and strengths and difficulties questionnaire were used as criterion validity tools.A retest was conducted one month later.SPSS 27.0 was used for descriptive statistics, item analysis, internal consistency test, test-retest reliability test and criterion validity test. AMOS 24.0 was used to perform confirmatory factor analysis .Results:Item analysis indicated significant positive correlations between each item and the subscales ( r=0.293-0.782, all P<0.01), with significant differences in scores between high and low groups ( t=10.079-37.038, all P<0.01).Confirmatory factor analysis supported a seven-factor structure for the social skills subscale(communication, cooperation, assertion, responsibility, empathy, engagement and self control) and a five-factor structure for the problem behavior subscale (externalizing, bullying, hyperactivity/inattention, internalizing and autism spectrum) of the SSIS-RS-C.There was a positive correlation between the social skills subscale and prosocial behavior ( r=0.637, P<0.001), and between the problem behavior subscale and social impairments and difficult behaviors ( r=0.765, 0.688, both P<0.001).The Cronbach's α coefficients for the total scale, social skills subscale and problem behavior subscale were 0.934, 0.972 and 0.963, respectively.The test-retest correlation coefficients for the total score and the two subscales were 0.665, 0.871 and 0.598, respectively (all P<0.001). Conclusion:The SSIS-RS-C demonstrated good reliability and validity in the Chinese adolescent population.

Objective:To compare minimally invasive surgery with traditional open surgery, analyze the current application status of health economic evaluations in the treatment of digestive tract cancers, such as esophageal cancer, gastric cancer, and colorectal cancer by minimally invasive surgery and provide evidence for the rational selection of clinical treatment, alleviation of disease-related economic burdens, and rational allocation of healthcare resources.Methods:By using five databases, i.e. China National Knowledge Infrastructure, Wanfang data, Chinese Biomedical Literature Database, PubMed, and Embase, a database was established to retrieve all the papers about health economic studies of minimally invasive surgery for esophageal cancer, gastric cancer, and colorectal cancer published until December 31, 2023. Literature was analyzed by using software NoteExpress 3.8, and data were processed using Excel 2021. The quality of included papers was evaluated using the CHEERS 2022 checklist, and Meta-analysis was conducted by using software Stata 17.0.Results:A total of 10 919 relevant papers were retrieved, and 59 studies were included. Only 14 studies (23.7%) used standard health economic evaluation methods. Meta-analysis results revealed no significant differences in direct medical expenditure and total expenditure between minimally invasive surgery and open surgery. However, the expenditure for minimally invasive surgery exhibited a significant increase [mean difference ( MD)=5 973.12 yuan, P<0.001], while hospital stay and indirect expenditure significantly decreased ( MD: -4.85 days and -733.79 yuan, P<0.001). In China, for gastric cancer, the direct medical expenditure of endoscopic surgery was lower than that of open surgery ( MD=-33 000.00 yuan) with no significant difference ( P<0.001). In colorectal cancer cases, the direct medical and surgical expenditures for laparoscopic surgery were higher than those for open surgery ( MD: 4 277.94 yuan and 4 267.80 yuan, P<0.001), while the indirect and total medical expenditures decreased ( MD: -768.34 yuan and -159.10 yuan). Hospital stays in patients who had minimally invasive surgery for all three types of cancer were shorter than those who had open surgery ( P<0.001). Conclusions:In the treatment of gastrointestinal cancer, compared with open surgery, minimally invasive surgery shows higher expenditure, but has advantages, such as shorter hospital stay and lower indirect expenditure, and there were no significant differences in direct medical and total expenditures between the two approaches. When conducting health economic evaluation, factors such as postoperative complications, hospital stay, and patient's economic status should be considered for their impact on total medical expenditure. It is necessary to pay attention to the application of health economic evaluations in healthcare decision-making.

Ventricular assist devices(VADs)have emerged as a pivotal therapeutic option for end-stage heart failure,undergoing significant technological advancements from pneumatic membrane pumps to continuous-flow centrifugal pumps.This review provides a detailed overview of several VAD models,including HeartMate Ⅲ,EVAHEART 2,and Heart Con.The initial generation of VADs established a foundation for subsequent developments,despite the occurrence of frequent complications.The second generation of VADs demonstrated a notable improvement in patient prognosis but carried the risk of ventricular collapse.The third generation of VADs represents a further reduction in size,incorporating magnetic levitation technology to enhance durability and blood compatibility.In the future,the development of VADs will focus on better emulating the physiological function of the native heart,improving pulsatility,and extending device longevity.As technology advances,VADs are expected to offer heart failure patients with a greater range of treatment options and a higher quality of life.

Purpose To investigate the clinicopathological features of traditional serrated adenoma(TSA).Methods A retrospective analysis was conducted on the clinical data,endoscopic,and pathological features of 200 TSA patients.HE staining and immunohistochemical staining were performed.The clinical pathological features were statistically analyzed using x2 test,and relevant literature was reviewed.Results There were 114 males(57.0％)and 86 females(43.0％),with ages ranging from 27 to 92 years(mean age 56.2 years).Among the patients,147(73.5％)were aged ≥ 50 years,and 53(26.5％)were aged＜50 years.Of the 207 TSA lesions,143(69.1％)were located in the distal colon and rectum,while 57(27.5％)were in the proximal colon and rectum.Endoscopic features included 72 lesions(34.8％)with a perpendiculated appearance,48 lesions(23.2％)with a flat appear-ance,and some exhibiting a pinecone-like appearance.The maximum diameter of the lesions was ≤ 10 mm in 136 ca-ses(65.7％),and＞10 mm in 71 cases(34.3％).The typical histopathological features of TSA included serrated contours,eosinophilic cytoplasm,pencil-like nuclei,and ectopic crypt foci.The most common pathological type was the classic TSA(152 lesions,73.4％),followed by the mucin-rich TSA(39 lesions,18.8％).12 cases(5.8％)of TSA exhibited high-grade intraepithelial neoplasia(HGIN)and 3 case(1.5％)of TSA progressed to carcinoma,con-sistent with TSA-originated colorectal cancer(TSA-CRC).Immunophenotype:in 34 cases TSA,Ki67 showed diffuse positivity in basal cells and scattered positivity on the surface.In all 35 cases TSA,p53 showed weak positive nuclear positivity(1％to 60％),and PTEN and MLH1 were retained.In the 12 cases of TSA with HGIN and 3 cases of TSA-CRC,Ki67 showed diffusely positive,CK20 was strongly positive diffusely,and MLH1 was retained.In 9 cases of TSA with HGIN,p53 was diffusely strongly positive,and in 12 cases,PTEN was lost.All 3 cases of TSA-CRC showed dif-fuse strong nuclear p53 positivity.The molecular detection showed there were BRAF V600E gene mutation in 8 cases.There were 6 cases with KRAS G12V mutation as well as 1 case with KRAS G13D mutation among the 7 cases of KRAS mutation.The primary surgical approach(111 cases,53.6％)was endoscopic mucosal resection(EMR).Conclu-sion TSA exhibits characteristic histological and endoscopic features.Lesions with a maximum diameter＞10 mum are more likely to progress to HGIN or adenocarcinoma.It is crucial to enhance the awareness of pathologists and clini-cians,particularly regarding TSA with atypical hyperplasia or invasive carcinoma,to avoid misdiagnosis and missed di-agnoses.

Ferroptosis is a programmed cell death depends on iron and lipid peroxidation,which has been recognized as the key pathogenic factor for the occurrence of various diseases in recent years,especially playing a significant role in neurodegenerative diseases.Ferroptosis triggers lipid peroxidation and oxidative stress in neuronal cells,leading to neuronal damage and death,thereby accelerating disease progression.Hydrogen sulfide,as an endogenous gaseous signaling molecule,exhibits multiple protective effects,including anti-inflammatory,antioxidant,and anti-ferroptosis properties.Hydrogen sulfide can effectively inhibit the occurrence of ferroptosis through various mechanisms,such as regulating iron metabolism,inhibiting lipid peroxidation,and enhancing the activity of antioxidant enzymes,thereby slowing down the progression of neurodegenerative diseases.This article reviews the related research progress on hydrogen sulfide and ferroptosis and ferroptosis-mediated neurodegenerative diseases,and analyzes the underlying mechanisms,aims to provide new insights and theoretical foundations for the treatment of neurodegenerative diseases.
