Panvascular diseases are systemic diseases with atherosclerosis as the pathological core， involving multiple vascular beds and target organs throughout the body. Due to their wide range and complexity， the traditional single-discipline prevention and treatment model struggles to meet the needs of systematic management， while clinical diagnosis often remains one-sided and insufficient， leading to delayed treatment. Literature reviews show that panvascular diseases involve a wide range of lesion sites， numerous influencing factors， and are prone to endangering life and health. It is urgent to construct a comprehensive and whole-course prevention and treatment management system， with vascular health as the goal and patients as the core. First， early screening and risk assessment should be conducted for high-risk groups. In terms of treatment decisions for patients， multi-disciplinary collaboration is needed to establish a scientific and standardized prevention and treatment path. Second， it is important to attach great importance to a people-centered approach， enhance patients' familiarity with the disease through cognitive intervention， and shift from passive treatment to active health care. Thirdly， it is needed to leverage the advantages of modern science and technology， promote the deep integration of artificial intelligence innovations and modern medicine， and help traditional diagnosis and treatment plans evolve towards precision， intelligence， and personalization. This will open up new paths for the modernization of the whole-course management of pan-vascular diseases. Fourth， efforts should be made to continue to carry forward and innovate the characteristics of traditional Chinese medicine， adhere to equal emphasis on modern and traditional medicine， promote complementary advantages and coordinated development of Chinese and Western medicine， and form a unique Chinese model for the whole-course management of panvascular diseases. Fifth， through the reintegration and redistribution of government， medical insurance， and medical resources， comprehensive talents in the broad vascular disciplines should be cultivated and an efficient hierarchical management model established， providing reference and guidance for the whole-course management of comprehensive diseases in the future.

OBJECTIVES: To investigate the protective effects of dexmedetomidine (DEX) against heat stress (HS)-induced oncosis in human skeletal muscle cells (HSKMCs) and its underlying mechanisms. METHODS: A HSKMC model of HS-induced oncosis were established by 43 ℃ water bath for 4 h, and the effects of treatments with 30 μmol/L DEX, ML385 (a Nrf2 inhibitor) +DEX, si-Nrf2+HS, and si-Nrf2+DEX prior to modeling on cell viability was assessed using CCK-8 assay. Oncosis characteristics were evaluated using transmission electron microscopy and Annexin V-FITC/PI flow cytometry. The oxidative stress markers (GSH, GSH-Px, MDA, SOD and ROS), mitochondrial membrane potential, energy metabolism, and inflammatory cytokines (TNF-α, IL-6 and IL-1β) in the cells were quantified using standard kits, and the expressions of porimin, caspase-3 and Nrf2 pathway proteins were analyzed using Western blotting and qRT-PCR. RESULTS: HS induced typical oncotic features in HSKMCs including organelle swelling and cytoplasmic vacuolization. DEX pretreatment significantly attenuated these changes, reduced Annexin V⁺/PI⁺ cell ratio and cellular porimin expression, and lowered the levels of ROS and MDA while restoring GSH and SOD levels. DEX pretreatment also significantly increased the mitochondrial membrane potential and ATP level, upregulated the expressions of Nrf2, p-Nrf2, HO-1 and NQO1, and suppressed the expressions of TNF-α, IL-6 and IL-1β. The protective effects of DEX were obviously attenuated by interventions with ML385 or si-Nrf2. CONCLUSIONS DEX mitigates HS-induced HSKMC oncosis by activating the Nrf2/HO-1 pathway to relieve oxidative stress, mitochondrial dysfunction, and inflammatory responses.

Extracorporeal membrane oxygenation (ECMO) is a key continuous extracorporeal life support technology that can partially or completely replace a patient's cardiopulmonary function, thereby winning valuable time for the diagnosis and treatment of the primary disease. With the widespread application of ECMO, the need for transport has increased. However, during transfers, the standard heater unit is often large and inconvenient to carry, while alternative warming measures tend to be ineffective. This frequently leads to complications such as hypothermia or the inability to maintain body temperature, which can seriously affect the patient's prognosis. In response to this challenge, the medical and nursing staff of the critical care medicine department at Zhongda Hospital Affiliated to Southeast University jointly designed an insulation device for ECMO transport pipelines. The device was successfully granted a National Utility Model Patent of China (patent number: ZL 2021 2 0653569.3). It primarily consists of key components such as a heating pad, velcro straps, a cover layer, a backing layer, an electric heating layer, and a wiring plug. Its advantages include portability, the ability to effectively wrap around and warm the ECMO circuit during transit, and a reduction in the incidence of hypothermia-related complications. Furthermore, its transparent material design allows for real-time monitoring of the ECMO system's status, making it both economical and practical.

Objective To investigate the relationship between stationing years of personnel on an island and their traditional Chinese medicine(TCM)constitution,thus providing a reference for adjusting the health status of stationed personnel,preventing and treating diseases.Methods Based on The Scale of Constitution in Chinese Medicine Questionnaire,TCM constitution of 734 personnel stationed on an island was investigated.Pearson χ2 method was used for data analysis.Results Of the 734 personnel stationed on an island 345(47.0%)were of the balanced constitution type and 389(53.0%)were of the biased constitution types.Among the people with biased constitution types,composite constitution accounted for 80.5%(313 people)and the simple accounted for the rest(19.5%,76 people).The top three types of the biased were dampness heat(15.2%),qi deficiency(14.0%),and yin deficiency(10.7%).The distribution of TCM constitution types was significantly different in terms of stationing years on the island(P<0.05).There was a significant difference in the balanced type and yin deficiency type between people with stationing time≤2 years and>8 years(P<0.05).There was a significant difference in qi deficiency type and qi depression type between people with stationing time≤2 years and>5 years(P<0.05).Compared to people with stationing time≤2 years,significant difference was found in yang deficiency type in people with stationing time ranging from 2 to 5 years and those with>8 years(P<0.05).There were significant differences in the phlegm dampness type,blood stasis type,and specific diathesis type between people with stationing time≤2 years and people with stationing time ranging from>2～5 years and>8 years(P<0.05).There were significant differences in the dampness heat type between people with stationing time≤2 years and people with stationing time ranging from>5～8 years and>8 years,between pepole with stationing time ranging from>2～5 years and people with stationing time>8 years(P<0.05).Conclusion The dampness heat type,qi deficiency type and yin deficiency type are common biased TCM constitution in personnel stationed on islands.The longer the time spent on islands,the greater the possibility of forming biased constitution.

Objective To reveal the thermally induced denaturation of wild-type human γ D-crystallin(HGD)and congenital cataract-related mutant(HGD P23T),and compare the differences in the structural changes between wild-type and mutants during a heating process.Methods HGD and HGD P23T were expressed and purified.The temperature-dependent intrinsic fluorescence intensity and static light scattering intensity of the protein samples were measured to reveal the temperature-dependent folding and aggregation structural changes of HGD and HGD P23T.Results When the temperature was below 70℃,the barycentric mean of the intrinsic fluorescence of HGD and HGD P23T shifted towards a longer wavelength with increasing temperature and the fluorescence intensity de-creased indicating the unfolded protein conformations.The conformational stability of HGD P23T was weaker than that of HGD.When temperature was higher than 70℃,the static light scattering intensity increased significantly with temperature,indicating protein aggregation upon heating.Relative to the wild-type,HGD P23T showed a stronger aggregation potency.Conclusions Heating disrupts the folding conformation of Γd-crystallin,induces the unfolded protein to aggregate.The disease-associated P23T mutation significantly reduces the conformational stability of Γd-crystallin.

In this paper， we systematically sorted out and verified the name， origin， producing area change， quality， efficacy and processing of Halloysitum Rubrum by consulting materia medica， medical books， prescription books from past dynasties， and modern literature， and combined with the comprehensive analysis of trait identification， hygroscopicity measurement and X-ray diffraction（XRD） detection， in order to provide a basis for understanding the original source of the mineral medicine. The results indicated that Halloysitum Rubrum was first contained in the Shennong Bencaojing， it had been consistently named Chishizhi， there were also aliases such as Chifu， Hongxinshi and Chiyouzhi. The description of Halloysitum Rubrum in ancient materia medica aligns with modern findings， categorizing it under the silicate kaolinite family， specifically polyhydrous kaolinite， with associated minerals mainly being dickite， nacrite， hematite， gibbsite， mica， etc. Historically， the production area of Halloysitum Rubrum was mainly located in the Qinling Mountains， Shandong and Henan， and is now primarily distributed in most parts of China， including Henan， Hubei and other provinces. Quality evaluation in ancient times included descriptions like "fresh and greasy color"， "delicately sticky tongue and lips" and "smooth as fat". Modern materia medica mostly evaluates its quality based on color， luster， texture and hygroscopicity， noting characteristics such as red color， smoothness， delicacy， softness and strong viscosity. Halloysitum Rubrum is sweet， sour and pungent in flavor， warm in nature， non-toxic， and belongs to the heart and large intestine meridians. It acts as an astringent and solidifying agent， particularly useful in the treatment of long-term dysentery and diarrhea， common processing methods include fire calcination， water flying， and vinegar quenching. Comprehensive analysis of the traits， XRD and humidity absorption of different batches of samples showed that the commercially available Halloysitum Rubrum is mainly bright red or brownish red， with a smooth surface like grease， soft and smooth texture， delicate cross-sectional texture， and some have waxy luster and strong water absorption. It is mainly composed of 10 Å（1 Å=0.1 nm） polyhydric kaolinite， and is often accompanied by 7 Å polyhydric kaolinite， nacrite， etc. Genuine products tend to have higher moisture absorption than counterfeit ones， which can be used as a key indicator to distinguish the authenticity. The quality evaluation of Halloysitum Rubrum aligns with historical materia medica， where "fresh color， delicate and greasy lips" could serve as a key feature for its quality evaluation.

Objective To observe the value of radiomics models based on gadolinium ethoxybenzyl diethylenetriamine pentaacetic acid(Gd-EOB-DTPA)enhanced hepatobiliary phase(HBP)MRI for assessing clinical pathological stage of hepatic fibrosis(HF).Methods Data of 240 patients with pathologically/clinically diagnosed and clinical pathological staged HF who underwent Gd-EOB-DTPA enhanced MR examination were retrospectively analyzed.The liver-to-muscle signal intensity ratio(SIR1)and liver-to-spleen signal intensity ratio(SIR2)were measured based on HBP images.Radiomics features of HBP images were extracted and screened to construct radiomics models.The signal intensity ratio(SIR)-radiomics combined models were constructed based on SIR and radiomics signatures.Receiver operating characteristic(ROC)curves were drawn to evaluate the efficacy of each model for assessing clinical pathological stage of HF.Results The area under the curve(AUC)of SIR1 and SIR2 models for assessing clinical pathological stage of HF were 0.63-0.70 and 0.65-0.71,respectively.The most effective radiomics model for assessing HF,significant HF,advanced HF and early cirrhosis was support vector machine(SVM),SVM,light gradient boosting machine and K-nearest neighbor model,respectively,with the AUC in validation set of 0.87,0.82,0.81 and 0.80,respectively,while the AUC of SIR-radiomics combined models in validation set of 0.88,0.82,0.82 and 0.81,respectively.Conclusion The radiomics models based on Gd-EOB-DTPA enhanced HBP MRI were helpful for assessing clinical pathological stage of HF.Combining with HBP SIR could improve their efficacy.

Objective To explore the genetic characteristics of fetuses with congenital heart diseases(CHD)diagnosed by prenatal ultrasound.Methods Data of 613 singletons with prenatal ultrasonic diagnosed CHD were retrospectively analyzed.The cardiac structural abnormalities were classified into 8 types.Whole-exome sequencing(WES)was performed for 40 fetuses since chromosomal karyotyping analysis and/or chromosomal microarray analysis(CMA)showed benign copy number variations(CNV)or variants of uncertain significance(VUS).Results Among 613 fetuses,479 fetuses underwent both chromosomal karyotyping analysis and CMA,genomic abnormalities were detected in 60 fetuses(60/479,12.53％).Among 134 fetuses underwent only CMA,genomic abnormalities were found in 4 fetuses(4/134,2.99％).According to results of chromosomal karyotyping analysis and/or CMA,abnormalities were noticed in 40 fetuses(40/568,7.04％)among 568 fetuses with isolated CHD,while in 15 fetuses(15/45,33.33％)among 45 fetuses with non-isolated CHD,respectively.Abnormality detection rate of chromosomal karyotyping analysis and/or CMA in fetuses with complex CHD(10/41,24.39％)was higher than that in fetuses with non-complex CHD(54/572,9.44％).Among complex CHD fetuses,abnormality detection rate was the highest in fetuses with conotruncal defect(CTD)combined with malformation of venous system(4/13,30.77％),while among fetuses with non-complex CHD,situs inversus viscerum had the highest detection rate(1/4,25.00％).Among 40 fetuses chromosomal karyotyping analysis and/or CMA showed benign CNV or VUS,WES indicated pathogenic CNV/likely pathogenic CNV(P/LP)in 3 fetuses,VUS in 3 fetuses and benign CNV in 34 fetuses.Conclusion Fetuses with CHD,especially extracardiac malformations had possibilities of genomic abnormalities.Fetuses with CTD combined with malformation of venous system had higher possibilities of genomic abnormalities.Compared with CMA alone,chromosomal karyotyping analysis combined with CMA was helpful for detecting genomic abnormalities.

BACKGROUND:Traditional Chinese medicine compound prescription has a long history in the treatment of primary osteoporosis,and the curative effect is definite,but the medication rule and mechanism are not clear. OBJECTIVE:Using the methodology of data mining and network pharmacology,to explore and verify the law of drug use and molecular mechanism of modern traditional Chinese medicine in the treatment of primary osteoporosis. METHODS:The relevant documents included in CNKI,WanFang,VIP and PubMed were used as data sources,and the relevant data were statistically counted and extracted by Microsoft EXCEL2019,IBMSPSS25.0 and other software.The high-frequency drugs obtained from the data statistics were analyzed by association rules analysis and cluster analysis,and the core drug combination of traditional Chinese medicine compound prescription in the treatment of primary osteoporosis was obtained by combining the two results.The therapeutic mechanism of this combination was explained by network pharmacology and verified by molecular docking. RESULTS AND CONCLUSION:Finally,151 articles were included and 207 prescriptions were selected,involving 285 flavors of Chinese herbs.(1)Ten groups of important drug combinations were obtained through the above two analyses,among which the core drug combination with the highest confidence and improvement was"Drynaria-Eucommia-Angelica."The key components of the combination in the treatment of primary osteoporosis were quercetin,kaempferol,naringenin and so on.The core targets were SRC proto-oncogene,phosphoinositide-3-Kinase regulatory subunit 1 and RELA proto-oncogene.The main pathways were cancer signaling pathway,JAK-STAT signaling pathway,VEGF signaling pathway,and NF-κB signaling pathway.(2)The key active components were docked with the core targets,and the two showed a good combination.To conclude,Chinese herbal compound therapy in the treatment of primary osteoporosis can use a variety of active components to exert its efficacy through multiple signal pathways and acting on multiple targets,which can provide a theoretical basis for the research and development of new drugs for the follow-up treatment of primary osteoporosis.
