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.

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.

Five novel nor-eremophilane-type sesquiterpenoids, peniroqueforins E-H and J (1-4 and 7), two new eremophilane-type sesquiterpenoids, peniroqueforins I and K (5 and 8), and a new eudesmane-type sesquiterpenoid, peniroqueforin L (9), along with four known compounds (6 and 10-12), were isolated and characterized from fungus Penicillium roqueforti (P. roqueforti). The structures and absolute configurations of these compounds were determined through comprehensive spectroscopic analyses, electronic circular dichroism (ECD) data analyses, and single-crystal X-ray diffraction methods. The anti-multi-drug resistance (MDR) cancer activity of these compounds was evaluated using SW620/Ad300 cells. Notably, the half maximal inhibitory concentration (IC₅₀) value of paclitaxel (PTX) combined with 1 in SW620/Ad300 cells was 50.36 nmol·L^-1, which was 65-fold more potent than PTX alone (IC₅₀ 3.26 μmol·L^-1). Subsequent molecular docking studies revealed an affinity between compound 1 and P-glycoprotein (P-gp), suggesting that this nor-eremophilane-type sesquiterpenoid (1) could serve as a potential lead for MDR reversal in cancer cells through P-gp inhibition.

Objective: To explore the latent class characteristics and related factors of health risk behaviors among higher vocational college students (referred to as vocational students) in the Wuling Mountain Area, so as to provide references for promoting their healthy development and formulating effective intervention measures. Methods: From April to June 2024, a stratified random cluster sampling method was used to survey 1 737 students from three higher vocational colleges in the Wuling Mountain Area (Xiangxi in Hunan, Enshi in Hubei, and Tongren in Guizhou). The study employed the Health risk Behavior Questionnaire for College Students, the Parent-Child Relationship Scale, the Social Support Scale, and the School Connection Scale for data collection. Latent class analysis (LCA) was used to examine the heterogeneous distribution characteristics of health risk behaviors among vocational students, and multivariate Logistic regression was applied to analyze the related factors of latent classes. Results: The LCA results identified three latent classes based on 12 health risk behaviors: the comprehensive high risk group (151 students, 8.7% ), the psychological distress group (883 students, 50.8%), and the low risk group (703 students, 40.5%). The distribution of latent classes showed statistically significant differences in gender and only child status ( χ 2=121.25, 9.85, both P <0.05). The low risk group scored higher in parent-child relationship (29.26±6.19), social support (63.98±18.16), and school connection (35.97± 7.71 ) compared to the comprehensive high risk group (27.28±6.03, 57.67±15.60, 32.97±7.55) and the psychological distress group (27.52±5.19, 62.06±14.54, 33.80±6.14) ( F =20.37, 23.51, 9.89, all P <0.05). Multivariate Logistic regression revealed that boys( OR =3.29) were more likely to belong to the comprehensive high risk group, social support ( OR =0.03, 0.21) and school connection ( OR =0.92, 0.96) were less likely to belong to both the comprehensive high risk and psychological distress groups (all P < 0.05). Conclusions There are three potential categories of healthharmful behaviors among vocational college students in Wuling Mountain Area. Schools, families and society should enhance the levels of parent-child relationship, school connections and social support for vocational college students of different categories to promote their physical and mental health development.

Objective:To investigate the clinical application value of expanded non-invasive prenatal testing(NIPT-plus)in screening for fetal chromosome copy number variations(CNV).Methods:From January 2021 to December 2023,141 pregnant women who voluntarily underwent amniocentesis at the Prenatal Diagnostic Centre of Urumqi Maternal and Child Health Hospital due to NIPT-plus suggesting a high risk of fetal CNV were selected.Amniotic fluid samples were collected for fetal chromosome karyotyping and chromosome microarray analysis(CMA).Pregnant women who underwent the above tests signed an informed consent form,and all cases were followed up forpregnancy outcome.Results:Among 141 NIPT-plus screen positive pregnant women,41 true posi-tive cases were detected by chromosomal karyotype analysis and CMA.The positive predictive value(PPV)for NIPT-plus screening for CNV was 29.08％(41/141).There was no statistically significant difference(P＞0.05)in the PPV of CNV detected by NIPT plus among different ages,indications and variant types.However,the PPV of CNV size＜10 Mb was significantly higher than that of CNV size≥ 10 Mb,and the difference was statistically signif-icant(39.62％vs.22.73％,P＜0.05).Among the 41 true positive cases,in addition to CNV,the CMA also detec-ted 7 cases of regions of Homozygosity(ROH),accounting for 17.07％(7/41)of the cases,two of which involved imprinted genes located on chromosomes 6 and 7.All continued pregnancy after genetic counselling and no signif-icant abnormalities were seen at neonatal follow-up after birth.Conclusions:NIPT-plus screening for fetal CNV has some clinical value,especially for CNV with fragment size＜10Mb,but accuracy needs to be further improved;CMA as a molecular diagnostic technique can detect ROH in cases where NIPT-plus suggests CNV abnormali-ties,and the combined use of the two techniques also opens new avenues for screening and diagnosis of prenatal imprinted diseases.

Objective:To investigate the difference in brain activity intensity between methamphetamine (MA) dependent patients (MA group) and healthy controls (control group) using fractional amplitude of low-frequency fluctuation (fALFF), and to establish a classification model between these two groups using support vector machine (SVM).Methods:From February 2014 to October 2019, a total of 46 male MA-dependent patients and 46 male healthy controls were recruited from the Affiliated Kangning Hospital of Ningbo University. The study collected resting-state functional magnetic resonance imaging (rs-fMRI) data and analyzed the differences in brain functional activity between the two groups. This analysis was conducted using both static and dynamic fractional amplitude of low-frequency fluctuations (d-fALFF). Additionally, the study examined the correlation between fALFF/d-fALFF values in specific brain regions and the total scores, as well as each factor score, of the Brief Psychiatric Rating Scale (BPRS). Furthermore, the relationship between fALFF/d-fALFF values and the age of first use and total dose of MA in the MA group was investigated. Finally, the fALFF map and d-fALFF map of brain regions with significant differences between groups were used as features for constructing classification.Results:Compared to the healthy control group, those dependent on MA showed significantly increased fALFF mainly in the nucleus accumbens, caudate nucleus, thalamus, and amygdala nucleus( t=-5.21--2.72, all P<0.05). The MA group exhibited decreased fALFF in the superior frontal gyrus, middle frontal gyrus, orbital gyrus, and cingulate gyrus( t=3.59-5.00, all P<0.05). Most of the brain regions with decreased d-fALFF overlapped with those exhibiting decreased fALFF( t=3.33-4.87, all P<0.05). The results of the correlation analysis showed that the fALFF value of the right nucleus accumbens was positively correlated with the age of first use of MA ( r=0.537, P<0.001). There is no significant relationship between the abnormal fALFF and d-fALFF values in the MA group and the total scores and each factor scores of BPRS, as well as the total dose of MA taken (after removing outliers). Based on fALFF and d-fALFF values, the SVM classifier achieved accuracies of 90.33%±6.89% and 71.56%±7.80%, respectively. Conclusions:There are significant abnormalities in the low-frequency fluctuation of the resting brain in patients dependent on MA. These abnormalities reflect the rigidity of prefrontal cortex activity, functional impairment, and dysfunction of the anti-reward system. These factors may be one of the causes for MA dependent behavior and repeated episodes. In addition, the fALFF values may be helpful for distinguishing MA dependent individuals from the control group.

As antibiotic resistance becomes increasingly concerning,antimicrobial peptides,as a new type of antibiotic alternative,have attracted more attention.However,the low enzymatic stability of antimicrobial peptides severely limits their clinical applications.To address this issue,researchers have developed various structural modification strategies,including the introduction of unnatural amino acids,peptide chain cyclization and chemical group modification.This article reviews the basic principles and cases of the above modification strategies analyzes the advantages and disadvantages of different modification strategies and recommends ways these strategies can be optimized.In addition,this article predicts the developments of and potential challenges to strategies for enhancing enzymatic stability of antimicrobial peptides in the hope of providing references for subsequent research and development of antimicrobial peptides.

AIM:To investigate the protective effect and mechanism of zinc ions on lung ischemia/reperfusion injury(LIRI)in rats.METHODS:SPF SD rats aged 6～8 weeks were divided randomly into 4 groups:control(control)group,ischemia/reperfusion(I/R)group,zinc chloride(ZnCl2)+I/R group,and PI3K inhibitor(LY294002)+ZnCl2+I/R group.Inductively coupled plasma mass spectrometry(ICP-MS)was used to measure the concentration of zinc ions in lung tissues,while the degree of lung tissue injury was assessed by HE staining,the alveolar damage index,and the lung wet/dry weight ratio.qPCR was used to detect the mRNA expression of solute carrier family 39 member 8(SLC39A8/ZIP8),with the TUNEL assay used to determine the level of apoptosis in lung tissue.The phosphorylation levels of caspase3,PI3K,AKT,GSK-3β,ZIP8,and solute carrier family 30 member 9(SLC30A9/ZNT9)were detected by Western blot,while the mitochondrial membrane potential was measured by the mitochondrial extraction kit and JC-1 mitochondrial mem-brane potential detection kit.RESULTS:Compared with the I/R group,the zinc ion level in the ZnCl2+I/R group in-creased(P<0.01),with the qPCR results showing that the expression level of ZIP8 also increased(P<0.01).The West-ern blot results demonstrated that the phosphorylation levels of PI3K/AKT/GSK-3β and cleaved caspase-3/pro were both in-creased(P<0.01 or P<0.05).In addition,the level of caspase-3 was decreased(P<0.01),the ZIP8 level was increased(P<0.05),whereas the level of ZNT9 was not significantly different(P>0.05).The mitochondrial membrane potential was increased(P<0.01)and the level of apoptosis was decreased(P<0.01).The results of HE staining,total lung water(TLW),lung index of quantitative assessment of histology(IQA),and lung tissue wet/dry weight ratio showed that the de-gree of injury was reduced significantly(P<0.05 or P<0.01).Compared with the ZnCl2+I/R group,the LY294002+Zn-Cl2+I/R group had a significant reduction in zinc ion levels(P<0.05),while qPCR showed a significant reduction in ZIP8 expression(P<0.01).Western blot showed that the phosphorylation level of PI3K/AKT/GSK-3β was decreased(P<0.01),the level of caspase-3/pro-caspase-3 was increased(P<0.01)the level of ZIP8 was decreased(P<0.05),al-though there was no significant difference in ZNT9(P>0.05).Measurements of the mitochondrial membrane potential demonstrated a significant decrease(P<0.01),while the TUNEL results showed that the level of apoptosis had increased(P<0.05).HE staining,TLW,IQA and lung tissue wet/dry weight ratio indicated that the degree of injury was aggravated significantly(P<0.05 or P<0.01).CONCLUSION:Administration of zinc chloride in rats has a protective role in lung ischemia/reperfusion injury by activating the PI3K/AKT pathway,leading to inactivation of GSK-3β,stabilization of the mitochondrial membrane potential level,and inhibition of cell apoptosis.

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.
