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.

Methods To investigate how the timing of cooling therapy affects organ injuries in rats with exertional heat stroke(EHS)and explore the possible mechanisms.Methods A total of 60 adult male Wistar rat models of EHS were randomized into model group without active cooling after modeling,immediate cooling group with cold water bath immediately after modeling,delayed cooling groups with cold water bath at 5,15 and 30 min after modeling,with another 12 mice without EHS as the normal control group.The changes in core body temperature of the mice were recorded and the cooling rate was calculated.After observation for 24 h,the mice were euthanized and blood samples were collected for detection of interleukin-1β(IL-1β),IL-2,IL-4,IL-6,IL-10,and interferon-γ,followed by pathological examination of the vital organs.The rats that died within 24 h were immediately dissected for examination.Results The number of deaths of the model rats within 24 h increased significantly with the time of delay of cooling treatment.The delay of cooling was positively correlated(r=0.996,P=0.004)while the cooling rate negatively correlated with the mortality rate(r=-0.961,P=0.009).The inflammatory cytokine levels presented with different patterns of variations among the cooling intervention groups.All the rat models of EHS had significant organ damages characterized mainly by epithelial shedding,edema,effusion,and inflammatory cell infiltration,and brain and renal injuries reached the peak level at 24 h after EHS.Conclusion EHS causes significant nonspecific pathologies of varying severities in the vital organs of rats,and the injuries worsen progressively with the delay of cooling.There is a significant heterogeneity in changes of serum inflammatory cytokines in rats with different timing of cooling intervention following EHS.

Objective:To investigate the association between serum uric acid,pulmonary function and airflow obstruction in Chinese Taiwan healthy subjects.Methods:All the cross-sectional analysis was performed in the population over 40 years old using the physical examination data of Chinese Taiwan MJ Health Resource Center between 1996 and 2016 stratification by gender.The correlation analyses between serum uric acid were done and multivariate Logistic regression analysis was used to explore the effect of serum uric acid on airflow obstruction.Results:A total of 35 465 people were included in the study,in-cluding 16 411 men and 19 054 women.Among them,the serum uric acid concentration of men was higher than that of women,and the serum uric acid concentration of the people with airflow obstruction was higher than that of the people without airflow obstruction.There was a negative correlation between serum uric acid level and the forced expiratory volume in one second(FEV1)and the force vital capacity(FVC)in women(P＜0.05),but in men the correlation didn't exist(P＞0.05).After adjusting for age,education,smoking status,drinking status,work strength,body mass index,history of cough,his-tory of hypertension,history of diabetes,history of dyslipidemia,white blood cells and blood albumin,the airflow obstruction in women was more likely to exist with the serum uric acid elevated(OR=1.12,95％CI:1.02-1.22,P＜0.05).The results showed that women with hyperuricemia were more likely to have airflow obstruction than those without hyperuricemia(OR=1.36,95％CI:1.06-1.75,P＜0.05).There was no correlation between serum uric acid concentration and airflow obstruction in men(OR=1.04,95％CI:0.96-1.13,P＞0.05),also the hyperuricemia and airflow obstruction(OR=1.12,95％CI:0.89-1.39,P＞0.05).Conclusion:There is a negative correlation between serum uric acid and FEV1 and FVC in relatively healthy women,and there is an association between elevated serum uric acid and airflow obstruction in women,but not in men.Further prospective studies are needed to explore whether high serum uric acid level can increase the risk of airflow obstruction.

Objective To carry out carrier screening for spinal muscular atrophy(SMA)in 3 302 preg-nant women from Xinjiang region and preliminarily determine the SMA carrier frequency among pregnant women in the region.Methods A total of 29 089 pregnant women who underwent prenatal visits at this hos-pital from April 2020 to February 2023 were educated,of whom 3 302 were received SMA carrier screening.SMA carriers were screened by detecting the copy numbers of SMN1 exons 7(E7)and 8(E8)using quantita-tive fluorescence PCR.Multiplex ligation-dependent probe amplification(MLPA)was used for prenatal diag-nosis of high-risk fetuses in couples who were both SMA carriers.Results The acceptance rate of SMA carri-ers screening was 11.35％.Among the 3 302 pregnant women,58 were found to be SMA carriers,and the total carrier frequency was 1.76％(1/57).Among them,there were 45 cases of Han ethnicity,with a carrying fre-quency of 1.63％(1/61),and there were 13 cases of ethnic minorities,with a carrying frequency of 2.39％(1/42).Among the 58 carriers,46 spouses were received SMA screening,and the results showed that two couples were both SMA carriers.Further prenatal diagnosis was performed,and the results of MLPA indicated that the fetuses were all heterozygous deletions of SMN1 E7 and E8,suggesting continued pregnancy.Conclusion This study has preliminarily determined the SMA carrier frequency among pregnant women in Xinjiang region.SMA carrier screening in pregnant women and prenatal diagnosis of high-risk fetuses are of great significance for the prevention and control of birth defects.

Objective To study the clinical effect of Kinesio Tape for treating the lower limb function in children with spastic cerebral palsy accompanied by knee hyperextension.Methods Sixty children with spastic cerebral palsy treated by rehabilitation therapy in this hospital from August 2017 to December 2018 were se-lected as the study subjects and divided into the experiment group and control group,30 cases in each group.The control group adopted the conventional rehabilitation therapy,while the experiment group was combined with Kinesio Tape on the basis of conventional rehabilitation therapy.The treatment course lasted for 3 months.Before and after treatment,the children patients conducted the Gross Motor Function Measure-88(GMFM-88)scoring,Modified Ashworth Scale(MAS)grading on the triceps surae muscle in the affected side,surface electromyography,measurement of dorsiflexion angle of foot in knee extension position and meas-urement of maximum knee extension angle of knee joint.Results The GMFM-88 score,triceps surae muscle MAS grade in the affected side,foot dorsiflexion angle in Knee extension position,maximum knee extension angle in the erect position in the two groups were improved compared with those before treatment(P＜0.05).Furthermore,the above indicators in the experimental group were superior to those in the control group(P＜0.05).The surface electromyographic value had no statistical difference between the two groups(P＞0.05).No obvious adverse reactions occurred during the treatment process with good compliance.The chil-dren's parents in the experiment group filled in Kinesio Tape satisfaction questionnaire,and had 100％satis-faction.Conclusion Kinesio Tape combined with routine rehabilitation therapy could effectively improve the muscular tension,joint activity,knee excessive extension degree and exercise function in children with spastic cerebral palsy accompanied by knee hyperextension.

Objective:To introduce the method of using anal fistula endoscope to treat chronic sinus tract leakage at rectal anastomosis site.Methods:We used anal fistula endoscopy to treat a patient with chronic sinus tract leakage after radical resection of rectal cancer, mainly including the following 5 steps: (1) establishing a water injection circulation system through the anus; (2) scraping off purulent coating and mucosa on the surface of the sinus tract with the brush; (3) hemostasis and removal of necrotic tissue with electrocoagulation rods; (4) filling the sinus tract with bioprotein gel; (5) compressing the sinus tract with transanal drainage tube.Results:The patient is a 70 year old male with rectal cancer. After undergoing 3D laparoscopic assisted radical resection of rectal cancer via abdominal anterior resection (Dixon's procedure) and diverting ileostomy surgery for more than 3 months, leakage of the rectal anastomosis was found through colonoscopy and anal iodine water contrast imaging .The patient started eating and flowing juice 6 hours after surgery, got out of bed 24 hours after surgery, and was discharged 48 hours after the removal of the anal canal. Three months after surgery, colonoscopy and transanal iodine hydrography showed that the sinus repair was intact. The diverting ileostomy was reduced 4 months after surgery.Conclusion:Anal fistula endoscope is safe and feasible for the treatment of chronic sinus tract anastomotic leakage in selected patients.
