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.

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.

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 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.

AIM:This study aimed to investigate the effect of ischemic post-conditioning(I-post-C)on lung ischemia-reperfusion injury(LIRI)in rats and relationship between I-post-C and zinc homeostasis.METHODS:SPF SD rats(6～8 weeks old)were randomly divided into four groups,with eight rats in each group:control group,ischemia/reper-fusion(I/R)group,I-post-C group and I-post-C+zinc ion chelator TPEN group.Inductively coupled plasma mass spec-trometry(ICP-MS)was used to measure the concentration of zinc ions in lung tissues.HE staining,lung wet/dry weight ra-tio(W/D),total lung water content(TLW),and index of quantitative assessment(IQA)of lung injury were used to detect the degree of lung tissue injury in each group.Mitochondrial membrane potential was measured using extraction and JC-1 mitochondrial membrane potential detection kits.TUNEL assay was used to detect the level of apoptosis in lung tissues.Western blot was used to detect the protein expression levels of caspase-3,solute carrier family 39 member 8(SLC39A8/ZIP8),solute carrier family 30 member 9(SLC30A9/ZNT9),and PI3K/AKT/GSK-3β in lung tissues of each group.RT-qPCR was used to detect ZIP8 and ZNT9.RESULTS:Compared to the control group,the I/R group showed significantly aggravated lung tissue injury(P<0.01),decreased zinc ion levels(P<0.01),enhanced cell apoptosis(P<0.05),re-duced mitochondrial membrane potential(P<0.01),decreased PI3K/AKT/GSK-3β phosphorylation levels(P<0.05,P<0.01),increased cleaved caspase-3/pro-caspase-3 ratio(P<0.01),and reduced ZIP8 expression(P<0.05).Compared to the I/R group,the I-post-C group exhibited alleviated injury(P<0.05 or P<0.01),increased zinc ion levels(P<0.01),reduced apoptosis(P<0.01),restored mitochondrial membrane potential(P<0.01),elevated PI3K/AKT/GSK-3β phosphorylation levels(P<0.05,P<0.01),decreased cleaved caspase-3/pro-caspase-3 ratio(P<0.05),and in-creased ZIP8 expression(P<0.05).Compared to the I-post-C group,the I-post-C+TPEN group demonstrated aggravated injury(P<0.01),decreased zinc ion levels(P<0.01),enhanced apoptosis(P<0.01),reduced mitochondrial membrane potential(P<0.05),decreased PI3K/AKT/GSK-3β phosphorylation levels(P<0.05,P<0.01),increased cleaved cas-pase-3/pro-caspase-3 ratio(P<0.05),and reduced ZIP8 expression(P<0.05).ZNT9 expression showed no significant differences among the groups(P>0.05).CONCLUSION:Ischemic postconditioning can improve LIRI by regulating zinc homeostasis,activating PI3K/AKT signaling pathway,inactivating glycogen synthase kinase 3β,inhibiting the de-cline of mitochondrial membrane potential,and antagonizing cell apoptosis in rats.

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.

Objective:To investigate the role and molecular mechanisms of transcription factor EB (TFEB) and its target genes in the treatment of multiple myeloma (MM) with bortezomib.Methods:TFEB target genes were predicted using the GTRD database (http://gtrd.biouml.org/), identifying Ptch1 gene for further study. Expression changes of Ptch1 in RPMI8226 and U266 MM cell lines after bortezomib treatment were assessed by real time fluorogenic quantitative PCR (RT-qPCR) and Western blot. RPMI8226 and U266 cell lines were transfected with siRNA-TFEB, and mRNA and protein levels of key factors (Ptch1, Gli1) in the Ptch1/Hedgehog signaling pathway were measured by RT-qPCR and Western blot. Furthermore, Ptch1 was overexpressed in MM cell lines via lentiviral transduction. Autophagy was evaluated by acridine orange staining, and protein levels of LC3B, Beclin-1, and Lamp-1 were measured by Western blot. Lysosomal quantity changes were assessed by lysosomal fluorescent probes.Results:Bortezomib (6.0×10 -6 mmol/L, 24 h) significantly reduced Ptch1 mRNA and protein levels in both cell lines compared with blank control group (all P<0.05). siRNA-TFEB transfection reversed bortezomib’s inhibition of Hedgehog pathway key factors Ptch1 and Gli. Ptch1 overexpression in bortezomib-treated RPMI8226 and U266 cells significantly reduced the relative expression of autophagy-related proteins LC3B, Beclin-1, and Lamp-1 (all P=0.001). Acridine orange staining showed fewer acidic vesicular organelles within two cell lines (all P=0.001). The relative fluorescence expressions of lysosomal probes reflecting the number of lysosomes were also decreased ( P values of RPMI8226 and U266 cell lines were 0.001 and 0.007, respectively) . Conclusion:The knockdown of TFEB can specifically promote the expression of the Ptch1/Hedgehog signaling pathway, thereby reducing bortezomib-induced autophagy in MM cells and reversing the inhibitory effect of bortezomib on the proliferation of MM cell lines.

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.
