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 investigate the contamination status of cloth mouse pads in dental clinics,and provide theoretical basis for standardizing environmental surface disinfection and scientific intervention in dental clinics.Methods The contamination status of cloth mouse pads in 5 dental clinics were investigated by adenosine triphos-phate(ATP)fluorescence detection method,visual observation method,and bacterial culture method.Disinfection efficacy of ultraviolet disinfection method and wiping disinfection using two types of disinfectant wipes on cloth mouse pads and photovoltaic glass mouse pads was compared.Intervention measures(using photovoltaic glass mouse pads,regular cleaning and disinfecting)were taken,and contamination status of cloth mouse pads in different departments before and after intervention was compared.Results The baseline investigation found that the conta-mination status of mouse pads varied in different dental clinics.The qualified rate of bacterial culture of mouse pads in department of endodontics was the lowest(20.00％),followed by the department of periodontology(30.00％).There was statistically significant difference in ATP detection values between two types of disinfectant wipes before and after wiping and disinfecting photovoltaic glass mouse pads(both P＜0.001).After using photovoltaic glass mouse pads,the contamination of mouse pads in 5 dental clinics was alleviated,and the qualified rate of ATP detec-tion increased(＞80％),compared with qualified rate of ATP detection before intervention,differences were all sta-tistically significant(all P＜0.001).Conclusion The contamination of the cloth mouse pads in dental clinics is seri-ous,and the conventional cloth mouse pad is difficult to be cleaned and disinfected.It is suggested that medical in-stitutions use the mouse pad which is convenient for cleaning and disinfection,and specify the disinfection method and frequency to control the contamination of the mouse pads.

Objective To explore the mechanism of Bushen Zhupai Decoction in treating ovarian fibrosis in polycystic ovary syndrome(PCOS)model rats based on IL-17/TRAF6/NF-κB signaling pathway.Methods Totally 60 SPF grade female SD rats were randomly divided into blank group,model group,Yousiyue group and TCM low-,medium-and high-dosage groups,with 10 rats in each group.The PCOS model was replicated by gavage of 1 mg/kg letrozole for 21 days.The Yousiyue group was given a 10 mg/kg solution of drospirenone ethinylestradiol tablets by gavage,TCM low-,medium-and high-dosage groups were given 8.82,17.64 and 35.28 g/kg of Bushen Zhupai Decoction by gavage,once a day for 28 consecutive days.HE and Masson staining were used to observe the morphology of ovarian tissue and ovarian fibrosis,the contents of serum IL-17,IL-18 and IL-1β were detected by ELISA,the mRNA expression of IL-17,TRAF6,NF-κB p65 and TGF-β1 in ovarian tissue were determined by RT-qPCR,the protein expression of TRAF6,NF-κB p65,TGF-β1,α-SMA,E-cadherin and the positive expression of IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA in ovarian tissue were detected by Western blot and immunohistochemical staining respectively.Results Compared with the blank group,the body mass,ovarian mass and ovarian index significantly increased of rats in model group,with follicular cystic dilation,thinning of granulosa cell layer,and significant increase in fibrosis positive range(P<0.01),the serum contents of IL-17,IL-18 and IL-1β significantly increased(P<0.01),the expressions of IL-17,TRAF6,NF-κB p65,TGF-β1 mRNA and IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA proteins significantly increased(P<0.01,P<0.05),the expression of E-cadherin protein significantly decreased(P<0.01).Compared with the model group,the ovarian index of rats in Yousiyue group and TCM medium-and high-dosage groups significantly decreased(P<0.01,P<0.05),the rats in TCM high-dosage group showed dominant follicles,increased thickness of granulosa cell layer,and significantly reduced fibrosis positive range(P<0.01),the serum contents of IL-17,IL-18 and IL-1β significantly decreased in Yousiyue group and TCM low-,medium-and high-dosage groups(P<0.01),the mRNA expressions of IL-17,TRAF6,NF-κB p65,TGF-β1,and the protein expressions of IL-17RA,TRAF6,NF-κB p65,TGF-β1 and α-SMA in ovarian tissue significantly decreaed in TCM high-dosage group(P<0.01,P<0.05),the expression of E-cadherin protein significantly increased(P<0.01).Conclusion Bushen Zhupai Decoction can decrease the body mass,improve the ovarian index,decrease the expressions of inflammatory factors and improve the status of ovarian fibrosis in PCOS rats.The mechanism may be related to the regulation of IL-17/TRAF6/NF-κB signaling pathway.

Diminished ovarian reserve (DOR) is a decrease in the number of available follicles in the ovaries and the quality of oocytes, which in turn affects follicle development, ovulation and sex hormone secretion, resulting in decreased fertility. Harmful chemical components in cigarette smoke, such as nicotine and benzopyrene, can interfere with the hypothalamic-pituitary-ovarian axis and impair ovarian reserve and function through apoptosis, autophagy, oxidative stress and DNA damage, which can directly affect ovarian granulosa cells and oocytes, causing oocyte development disorders, increased apoptosis of granulosa cells, destroy reproductive endocrine homeostasis, lead to DOR and affect female fertility. At present, the molecular mechanism of premature ovarian dysfunction caused by cigarette smoke is not fully understood. In this paper, the molecular mechanism of cigarette smoke exposure affecting ovarian tissue and mediating ovarian function was reviewed, aiming to provide theoretical reference for the study of cigarette smoke induced DOR and affecting ovarian function, and to provide pregnant guidance for infertile women in bad environment and bad living habits.

The cerebellum plays a critical role not only in motor control but also in reward processing, emotional regulation, and addictive behaviors.Addictive behaviors alter the cerebellum’s neurotransmitter systems and synaptic connections, leading to dysfunction and reinforcing the persistence of addiction.This review summarizes the anatomical and functional foundations of the cerebellum in the reward circuitry and explores how cerebellar synaptic plasticity influences brain function in both substance and behavioral addictions. Furthermore, the potential role of the cerebellum in the progress of addiction and its clinical application prospects in addiction treatment are also discussed.

Objective To explore the value of radiomics model and deep learning model based on unenhanced MRI in predicting microvascular invasion(MVI)of hepatocellular carcinoma(HCC)preoperatively.Methods A total of 189 patients with postopera-tive pathologically confirmed HCC from two centers were retrospectively selected,of which 119 cases from Zhujiang Hospital of Southern Medical University were used as the training set[60 cases with negative MVI,59 cases with positive MVI],and 70 cases from Shenzhen People's Hospital were used as the external test set[38 cases with negative MVI and 32 cases with positive MVI].Clinical indicators were analyzed by univariate and multivariate logistic regression analysis and the independent predictors of positive MVI were screened.Deep transfer learning(DTL)and traditional radiomics methods were used to construct radiomics model and deep learning model based on unenhanced MRI.The predictive performances of each model were compared using receiver operating charac-teristic(ROC)curves and area under the curve(AUC).DeLong test was employed to compare statistical differences in performance of the models.Results Alkaline phosphatase(ALP)and prothrombin time(PT)were independent predictors of positive MVI(P<0.05).The deep learning model based on T2WI had the best predictive efficacy,with AUC of 0.779[95%confidence interval(CI)0.696-0.863]and 0.741(95%CI 0.620-0.861)in the training set and external test set,respectively,and there were statistically significant differences compared with the radiomics model and the clinical model based on T1WI(P<0.05).Conclusion Deep learning model based on T2WI has a certain application value in preoperative noninvasive prediction of MVI status in HCC patients.

Objective:To investigate the impact of circumferential tumor location (anterior wall, nonanterior wall, or circumferential) on circumferential resection margin (CRM) status, local recurrence, and survival in patients with mid-low rectal cancer.Methods:A retrospective cohort study was conducted using data from 696 patients with mid-low rectal adenocarcinoma who underwent surgery in the Department of Colorectal Surgery at the First Affiliated Hospital of Naval Medical University between December, 2018 and December, 2019. Based on MRI or contrast-enhanced CT findings, the rectal wall was divided into four quadrants: anterior, posterior, left, and right. Tumors were classified into three groups: anterior wall group ( n = 245), nonanterior wall group ( n = 286, tumors predominantly located on the posterior or lateral walls), and circumferential group ( n = 165, tumors involving ≥ 3/4 of the circumference). Propensity score matching (PSM) was used to balance baseline characteristics. Outcomes included pathological CRM positivity, local recurrence rate (LRR), overall survival (OS), and disease-free survival (DFS). Cox regression analysis was performed to identify risk factors for recurrence, and subgroup analysis was conducted in patients who did not receive neoadjuvant therapy. Results:After PSM, both the anterior and circumferential groups had significantly higher pathological CRM positivity rates compared to the nonanterior wall group ( P=0.040 and P=0.039, respectively). The median follow-up time was 64 months (range: 1-71 months). Compared to the nonanterior wall group, the anterior wall group also had a significantly higher 5-year LRR (8.8% vs. 2.3%, P=0.003), and significantly lower 5-year OS (80.7% vs. 91.6%, P=0.001) and DFS (76.6% vs. 84.6%, P=0.029). The circumferential group had a significantly higher 5-year LRR than the nonanterior wall group (11.4% vs. 3.8%, P=0.020), but no significant differences were observed in 5-year OS (81.8% vs. 89.5%, P=0.100) or DFS (70.7% vs. 78.3%, P=0.101). No significant differences were found between the anterior and circumferential groups in 5-year LRR (11.1% vs. 9.7%), OS (76.3% vs. 83.7%), or DFS (69.8% vs. 74.1%) either (all P>0.05). Cox univariate analysis and multivariate analysis identified anterior wall tumors (HR=3.751, 95%CI: 1.373-10.215, P=0.010), circumferential tumors (HR=3.240, 95%CI: 1.109-9.466, P=0.032), pathological CRM positivity (HR=3.071, 95%CI: 1.144-8.245, P=0.026), and lymph node metastasis (HR=2.584, 95%CI: 1.192-5.601, P=0.016) as independent risk factors for LRR. Conversely, a greater distance from tumor to the anal verge (per 1 cm increase, HR=0.831, 95%CI: 0.712-0.970, P=0.019), and neoadjuvant therapy (HR=0.442, 95%CI: 0.204-0.957, P=0.038) were identified as independent protective factors against LRR. In patients who did not receive neoadjuvant therapy, locally advanced nonanterior wall tumors exhibited markedly low LRR (1.3% for pathological stage II-III, 1.6% for pT3-4 stage). Conclusion:Rectal tumors located in the anterior wall or involving the circumference are associated with higher CRM positivity rates, increased local recurrence, and poorer survival. These patients should be prioritized for neoadjuvant therapy. In contrast, nonanterior wall tumors have a low recurrence rate, and selective omission of neoadjuvant therapy may be considered for these cases.

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.
