Panvascular disease， with vascular diseases as the common pathological feature， is mainly manifested as atherosclerosis. Panvascular disease mainly affects the important organs of the heart， brain， kidney， and limbs. It is one of the leading causes of death for Chinese residents at present. Previously， due to the narrow branches of disciplines， too much attention was paid to local lesions， resulting in the neglect of panvascular disease as a systemic one. The fact that panvascular disease has overall pathology and comprehensive and individualized treatment strategies， makes the disease highly compatible with the principles of holism concept and syndrome differentiation and treatment in traditional Chinese medicine （TCM）. It is believed that blood stasis is the core pathogenesis of atherosclerosis and is involved in the whole process of atherosclerosis. The theories of ''blood vessel''， ''meridians''， ''visceral manifestation''， and ''organs-meridians'' in TCM are helpful to comprehensively understand the complexity of panvascular diseases. Moreover， those theories can provide systematic treatment strategies. The TCM syndromes of panvascular diseases evolve from ''phlegm， stasis， stagnation， and deficiency''. Panvascular arteriosclerosis is related to the syndrome of ''stasis and phlegm''， and the treatment mainly promotes blood circulation and removes phlegm. There are different specific drugs and mechanisms of action for coronary atherosclerosis， cerebral atherosclerosis， and renal artery atherosclerotic stenosis. Panvascular venous lesions are related to the syndrome of ''deficiency and stasis'' in TCM， and the TCM treatment mainly invigorates Qi and promotes blood circulation， which can inhibit venous thrombosis， improve venous ulcers， and resist venous endothelial damage. Panvascular microcirculatory lesions are inseparable from the ''stagnation and stasis'' in TCM， and the treatment mainly promotes Qi and dredges collaterals， which has a good effect on coronary microvascular lesions， diabetic microvascular lesions， pulmonary microvascular lesions， and pancreatic microvascular lesions. Panvascular lymphatic lesions are related to the syndrome of ''water and stasis'' in TCM. The treatment method focuses on promoting blood circulation and water excretion， which can promote lymphangiogenesis and enhance lymphatic reflux. In addition， the combination of TCM and modern technology， especially the application of artificial intelligence， can improve the efficiency of early identification and personalized treatment， resulting in early screening and comprehensive management of panvascular diseases. Therefore， TCM will play a vital role in the prevention and treatment of panvascular diseases.

Objective:To discuss the damage effect of vesicular stomatitis virus(VSV)on the vascular endothelial(VE)barrier,and to clarify its mechanism.Methods:The canine kidney cells were used to amplify VSV.The half tissue culture infective dose(TCID50)of VSV was determined using mouse brain endothelial tumor bEnd.3 cells,and subsequent experiment was conducted using 300 times the TCID50.The bEnd.3 cells were divided into infection 0 h group,infection 4 h group,infection 8 h group,and infection 12 h group for VE barrier damage experiments due to VSV infection.The bEnd.3 cells were also divided into control group,infection group,and correction group for experiments to inhibit the VSV replication and restore the VE barrier.The bEnd.3 cells were inoculated into Transwell chambers to construct an in vitro VE barrier model.Cell voltage resistance meter was used to detect the transepithelial resistance(TER)in various groups after the bEnd.3 cells were infected with VSV at different time points;fluorescein isothiocyanate-dextran leakage assay was used to detect the permeability coefficients of the cells in various groups;immunofluorescence staining was used to observe the localization changes of VE-cadherin,β-catenin,and phosphorylated β-catenin(p-β-catenin)in cytoskeleton and adherens junctions(AJs)of the bEnd.3 cells after VSV infection;real-time fluorescence quantitative PCR(RT-qPCR)method was used to detect the expression levels of Wnt and β-catenin mRNA in the cells in various groups;Western blotting method was used to detect the expression levels of Wnt,β-catenin,and p-β-catenin proteins in the cells in various groups.Results:The TCID50 of VSV was 10-4.5·100 μL-1.TheTranswell chamber experiment results showed that compared with infection 0 h group,the TERs in the cells in the other groups were significantly decreased(P＜0.05),and the permeability coefficients were significantly increased(P＜0.05).The immunofluorescence staining results showed that compared with control group,the cytoskeleton of the bEnd.3 cells in infection group was disordered,the cell gaps was increased,the linear index of AJs was significantly decreased(P＜0.05),and β-catenin and p-β-catenin translocated from the cell membrane to the perinuclear area.The RT-qPCR results showed that compared with infection 0 h group,the expression levels of Wnt mRNA in the cells in the other groups were significantly decreased(P＜0.05),while the expression levels of β-catenin mRNA showed no statistically significant difference(P＞0.05).The Western blotting results showed that compared with infection 0 h group,the expression levels of Wnt protein in the cells in the other groups were significantly decreased(P＜0.05),the expression levels of β-catenin showed no statistically significant differences(P＞0.05),and the expression levels of p-β-catenin were significantly increased(P＜0.05).After inhibiting the VSV replication and correcting the low density lipoprotein receptor(LDLR)abnormalities,the Transwell chamber experiment results showed that compared with infection group,the TER in the cells in correction group was significantly increased(P＜0.05),and the permeability coefficient was significantly decreased(P＜0.05).The immunofluorescence staining results showed that compared with infection group,the gaps in the cells in correction group were reduced,and the perinuclear aggregation of β-catenin and p-β-catenin in the cells was restrained.The RT-qPCR results showed that compared with infection group,the expression level of Wnt mRNA in the cells in correction group was significantly increased(P＜0.05).The Western blotting results showed that compared with infection group,the expression level of Wnt protein in the cells in correction group was significantly increased(P＜0.05),the expression level of β-catenin showed no statistically significant difference(P＞0.05),and the expression level of p-P-catenin was significantly decreased(P＜0.05).Conclusion:VSV infection can cause the LDLR inactivation,reduce the expression level of Wnt protein,increase the phosphorylation level of β-catenin and cause its internalization,disrupt the stability of AJs,and ultimately lead to VE barrier damage.

AIM:To investigate the molecular mechanism of long noncoding RNA(lncRNA)SNHG1 in regu-lating ferroptosis to alleviate inflammation in CHME-5 human microglia induced by HIV-1 gp120 V3 loop.METHODS:CHME-5 human microglia were cultured in vitro,and were divided into 7 groups:blank group,random peptide group,gp120 V3 loop group(HIV-1 gp120 group),HIV-1 gp120+shCon group,HIV-1 gp120+SNHG1 sh2 group,HIV-1 gp120+SNHG1 sh2+ferrostatin-1(Fer-1;ferroptosis inhibitor)group,and HIV-1 gp120+SNHG1 sh2+EX527(Sirt1 in-hibitor)group.Normal CHME-5 cells were treated with random peptide or gp120 V3 loop for 24 h.After pretreatment of SNHG1 sh2 cells with inhibitors for 2 h,the cells were then treated with gp120 V3 loop for 24 h.The levels of inflammato-ry cytokines in the cell supernatants were detected by ELISA.Western blot was used to detect the protein expression levels of solute carrier family 7 member 11(SLC7A11),glutathione peroxidase 4(GPX4),Sirt1 and p53.Microplate reader was used to detect the levels of intracellular ferrous ion(Fe2+)and malondialdehyde(MDA).RESULTS:(1)The results of ELISA showed that the expression levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6)and IL-1β in HIV-1 gp120 group were significantly higher than those in blank group(P<0.05).Compared with HIV-1 gp120 group,the ex-pression levels of inflammatory cytokines in HIV-1 gp120+SNHG1 sh2 group were significantly decreased(P<0.05).Compared with HIV-1 gp120+SNHG1 sh2 group,the expression levels of inflammatory factors in HIV-1 gp120+SNHG1 sh2+Fer-1 were significantly decreased(P<0.05),but those in HIV-1 gp120+SNHG1 sh2+EX527 group were significant-ly increased(P<0.01).(2)The results of Western blot showed that compared with blank group,the expression levels of ferroptosis-related proteins SLC7A11 and GPX4 in HIV-1 gp120 group were significantly down-regulated(P<0.01).Com-pared with HIV-1 gp120 group,the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2 group were sig-nificantly up-regulated(P<0.01).Compared with HIV-1 gp120+SNHG1 sh2 group,the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2+Fer-1 group were significantly up-regulated(P<0.05),but the expression levels of SLC7A11 and GPX4 in HIV-1 gp120+SNHG1 sh2+EX527 group were significantly down-regulated(P<0.01),and the expression level of p53 was significantly up-regulated(P<0.05).(3)Compared with blank group,the levels of Fe2+and MDA in HIV-1 gp120 group were significantly increased(P<0.05).Compared with HIV-1 gp120 group,the levels of Fe2+and MDA in HIV-1 gp120+SNHG1 sh2 group were significantly decreased(P<0.01).Compared with HIV-1 gp120+SNHG1 sh2 group,Fe2+and MDA in HIV-1 gp120+SNHG1 sh2+Fer-1 group were significantly decreased(P<0.05),but those in HIV-1 gp120+SNHG1 sh2+EX527 group was significantly increased(P<0.05).CONCLUSION:Knockdown of SNHG1 can attenuate the inflammation in microglia induced by HIV-1 gp120 V3 loop,which may be achieved by regulating ferrop-tosis-related signaling molecules through the Sirt1/p53 signaling pathway.

Missed diagnosis can often be noted in mild traumatic brain injury (mTBI), resulting from atypical symptoms, diverse performances and subjectively dependent report. Blood biomarkers can not only reflect the pathophysiological process of mTBI to a certain extent, but also have important clinical value in assessing brain injury severity and predicting adverse outcomes. This article systematically describes the research progress of blood biomarkers that can assist mTBI diagnosis, distinguish CT manifestations and predict prognoses in recent years, aiming to provide references for clinical application of blood biomarkers in mTBI.

Objective To investigate the effect of thalidomide combined with infliximab (IFX) in treatment of refractory inflammatory bowel disease (IBD) and its effects on insulin-like growth factor-1 (IGF-1) and transforming growth factor-β1 (TGF-β1). Methods A total of 120 patients with refractory IBD were randomly divided into experimental group and control group, with 60 cases in each group. The two groups were given conventional treatment (mesalazine), the control group was given IFX, and the experimental group was given IFX combined with thalidomide, continuous treatment for two months. The efficacy, intestinal flora disturbance rate, adverse reactions, Crohn's disease activity index (CDAI), Lewis score, serum IGF-1, TGF-β1 levels and nutritional status indexes[albumin (ALB), transferrin (Tf)]before and after treatment for 1 month and 2 months of the two groups were compared. Results The total effective rate of the experimental group was significantly higher than that of the control group (P < 0.05). After one month and two months of treatment, CDAI and Lewis scores of the experimental group were significantly lower than those of the control group (P < 0.05); the serum levels of IGF-1, TGF-β1 as well as ALB and Tf in the experimental group were significantly higher than those in the control group (P < 0.05). The improvement of intestinal flora disturbance rate in the experimental group was significantly better than that in the control group (P < 0.05). There was no significant difference in the incidence of oral and nasal mucosa dryness, throat discomfort, nausea and vomiting between two groups (P>0.05). Conclusion In the treatment of refractory IBD patients, thalidomide combined with IFX can regulate serum IGF-1 and TGF-β1 levels, effectively relieve clinical manifestations, inhibit inflammatory activities, and improve nutritional status and intestinal flora disorders of patients, and it has high safety.

Metformin has been used for the treatment of type II diabetes mellitus for decades due to its safety, low cost, and outstanding hypoglycemic effect clinically. The mechanisms underlying these benefits are complex and still not fully understood. Inhibition of mitochondrial respiratory-chain complex I is the most described downstream mechanism of metformin, leading to reduced ATP production and activation of AMP-activated protein kinase (AMPK). Meanwhile, many novel targets of metformin have been gradually discovered. In recent years, multiple pre-clinical and clinical studies are committed to extend the indications of metformin in addition to diabetes. Herein, we summarized the benefits of metformin in four types of diseases, including metabolic associated diseases, cancer, aging and age-related diseases, neurological disorders. We comprehensively discussed the pharmacokinetic properties and the mechanisms of action, treatment strategies, the clinical application, the potential risk of metformin in various diseases. This review provides a brief summary of the benefits and concerns of metformin, aiming to interest scientists to consider and explore the common and specific mechanisms and guiding for the further research. Although there have been countless studies of metformin, longitudinal research in each field is still much warranted.

Objective:To investigate the value of central vein sign (CVS) and iron deposition on quantitative susceptibility imaging (QSM) of 3.0 T MRI in differentiating multiple sclerosis (MS) from neuromyelitis optica spectrum disease (NMOSD).Methods:This study was a retrospective study. A total of 54 MS patients and 49 NMOSD patients were enrolled from July 2018 to December 2020 in People′s Hospital of Leshan and the First Affiliated Hospital of Chongqing Medical University. All patients underwent conventional MRI and three-dimensional enhanced T 2*-weighted angiography (3D-ESWAN), and ESWAN-filtered phase and QSM were reconstructed from 3D-ESWAN data. First, brain lesions of MS and NMOSD were screened on proton density (PD)-T 2WI, and then the location of lesions, CVS and nodular/annular iron deposition were observed on phase and QSM images. The χ 2 test was used to compare the differences in intracranial lesion location, CVS and iron deposition between MS and NMOSD patients. Receiver operating characteristic curve and area under the curve (AUC) were used to assess the efficiency of CVS and QSM iron deposition to differentiate MS from NMOSD. Results:A total of 968 MS lesions were observed in 54 MS patients, of which CVSs were found in 354 lesions and 227 CVSs were located around the lateral ventricles, 117 in deep white matter (DWM) and 10 in the cortex/subcortex; 372 lesions showed nodular iron deposition, and 193 lesions ring iron deposition on QSM. Totally 247 brain lesions were observed in 41 of 48 patients with NMOSD, of which CVSs were found in 4 lesions and 1 located around the lateral ventricle, 3 located in the DWM; 3 lesions showed nodular iron deposition on QSM. There were significant differences in cortex/subcortex lesions, CVS and iron deposition between MS and NMOSD patients (χ 2 were 29.33, 115.66 and 258.21, respectively, all P<0.001). The AUC of CVS for differentiating MS from NMOSD was 0.941 (95%CI 0.887-0.994), with a sensitivity of 96.3% and a specificity of 91.8%; the AUC of iron deposition for differentiating MS from NMOSD was 0.969 (95%CI 0.930-1.000), with a sensitivity of 100% and a specificity of 93.9%. Conclusion:CVS and iron deposition on 3.0 T MRI are distinct radiologic features of MS lesions from those of NMOSD lesions, and have certain value in the differential diagnosis.

Promoting balanced distribution of medical resources and realizing high-quality sharing of basic medical services between urban and rural areas are an important part of common prosperity. Huzhou urban medical alliance was a new urban and rural of medical alliance mode based on level 4 vertical integration, which played an important role in the whole evolution process of the medical alliance. This medical alliance had not only broken through the " integration of counties" but also explored the " integration of cities" . It was a bridge connecting counties and cities, which was of great significance in narrowing the gap between urban and rural medical health services. The construction of urban medical alliance took digital transformation and systematic integration as two breakthroughs to comprehensively promote the upgrade of energy efficiency and benefit stacking of health governance. In 2021, the grass-roots medical utilization rate and county-level medical utilization rate were 72.7% and 90.6%. In 2020, the average hospitalization cost(8 726.7 yuan)and the average outpatient and emergency expenses(239.6 yuan)of public hospitals were 25.0% and 8.6% lower than the average level of Zhejiang Province, respectively. Although Huzhou city had broken through the restrictions of administrative divisions and actively promoted the construction of the medical alliance, and achieved phased results, there were still structural defects and institutional difficulties. In order to solve these problems, the author proposed to promote the improvement of governance structure and optimization of governance system through " three governance" and " three characteristics" , and then promote the high-quality development of urban medical alliances.
