In the context of burgeoning economic trade, there has been a remarkable increase in the number of ships travelling between domestic and international ports. Inbound and outbound cargo ships, cruise liners, ferries, and other types of vessels have emerged as critical vehicles for the dispersal of vector organisms and the spread of infectious disease agents. Public health concerns associated with these vessels represent a significant threat to human welfare. In this paper, we comprehensively review the hazards posed by vector organisms on ships, the latest advances in prevention and control strategies, and proposes appropriate countermeasures. The aim is to provide effective guidance for the prevention and control of public health security issues caused by ship-borne vector organisms.

Objective To investigate the possible association between cross-domain associative memory(AM)impairment and hippocampal subfield volumes in patients with schizophrenia(SCZ).Methods We enrolled 28 SCZ patients from Shanghai Mental Health Center,Shanghai Jiao Tong University School of Medicine,and 28 healthy controls(HCs)between 2019 and 2021.Based on an innovative AM paradigm and automated segmentation,3D-T1 weighted data of the objects were processed with PhiPipe and FreeSurfer.Differences in subfield volums between the two groups were analyzed using ANCOVA,while their relationship with AM scores was assessed using Pearson correlation.Results SCZ patients exhibited significantly poorer AM performance across three conditions compared with HCs.Marginally significant reductions were observed in the total volume of bilateral hippocampus,encompassing both the hippocampal head and body.Significant volume reductions were identified in the bilateral presubiculum and parasubiculum.The volumes of bilateral presubiculum head(r=0.273,P=0.042),parasubiculum(r=0.397,P=0.002),and CA1 head(r=0.382,P=0.004)exhibited positive correlations with cross-domain AM performance.Conclusion The bilateral presubiculum and parasubiculum,as hippocampal subregions significantly associated with cross-modal AM deficits in SCZ,may play a crucial role in the pathology of AM.

AIM To investigate the effect of Fuzheng Hefu Zhiyang Formula(FZHFZY)on psoriasis-like skin lesions and immune regulation in mice.METHODS In the in vivo experiment,30 BALB/c mice were randomly divided into the blank group,the model group,the dexamethasone group(1.5 g/kg of compound dexamethasone acetate cream),and the low-dose(2.5 g/kg)and high-dose(5 g/kg)FZHFZY groups,with six mice in each group.The experiment groups were treated with respective FZHFZY and dexamethasone,and the other groups were given normal saline for 10 consecutive days,during which psoriatic skin lesions were induced with imiquimod cream for 7 consecutive days.The mice had their area and severity of psoriasis assessed by PASI score;their histological changes of skin lesions.observed with Hematoxylin-eosin(HE)staining;their F4/80 ratio of skin lesions observed with immunohistochemical(IHC)staining;their protein expressions of P38,p-P38,Erk,p-Erk,P65 and p-P65 detected by Western blot;and their mRNA expressions of tumor necrosis factor-α(TNF-α),IL-17,IL-23 and IL-1β detected by RT-qPCR.In the in vitro research,the cultured RAW264.7 cells were divided into the blank group,the LPS group,and the FZHFZY groups(1 200,600,300,150 μg/mL).The cells had their protein expressions of P38,p-P38,Erk,p-Erk,P65 and p-P65 detected with Western blot;and their mRNA expressions of IL-6,TNF-α,IL-23 and IL-8 detected by RT-qPCR.RESULTS The in vivo experiment showed that compared to the model group,the FZHFZY groups demonstrated decreased PASI score(P＜0.01);improved epidermal thickening and parakeratosis of skin lesions as revealed by HE staining result and increased expression of F4/80 in IHC staining sections;decreased protein expression ratios of p-P38/P38,p-ERK/Erk and p-P65/P65 in skin(P＜0.05,P＜0.01);and reduced mRNA expressions of TNF-α,IL-17,IL-23 and IL-1β in the skin(P＜0.01).FZHFZY(0～2 400 μg/mL)showed no significant cytotoxicity towards RAW264.7 cells in vitro(P＞0.05).Compared to those of the LPS group,the cells exposed to FZHFZ at concentrations of 1 200 and 600 μg/mL demonstrated decreased protein expression ratios of p-P38/P38,p-ERK/Erk,and p-P65/P65(P＜0.05,P＜0.01);and significantly decreased mRNA expressions of TNF-α,IL-17,IL-23 and IL-1β(P＜0.01).CONCLUSION FZHFZY alleviates imiquimod-induced psoriatic lesions in mice and suppresses inflammatory response in LPS-stimulated RAW264.7 cells by inhibiting P38/Erk/NF-κB signaling pathway.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective:To explore the distribution variation of ultrasound-detected inflammatory lesions with clinical signs in patients with psoriatic arthritis (PsA).Methods:This was based on the Peking University First Hospital Psoriatic Arthritis (PKUPsA) cohort. Patients enrolled from January 2019 to June 2024 were inchuded, patients with complete data of physical examination and ultrasonographic evaluations of 62 joints in the hand and foot. The ultrasound-detected inflammatory lesions including synovitis, tenosynovitis, enthesitis, and soft tissue inflammation were compared with joint tenderness/swelling. The χ2 test was employed to analyze differences between groups. Results:A total of 7 440 joints in 120 PsA patients were included. Overall, the proportion of joints with clinical signs (tenderness or swelling) was higher than those with ultrasound-detected inflammatory lesions [9.14%(680/7 440) vs. 7.93%(590/7 440), χ2=1 245.928, P<0.001], with more tenderness joints than swelling joints [7.72%(574/7 440) vs. 6.14%(457/7 440), χ2=3 264.45, P<0.001]. Clinical signs were primarily observed in hand proximal interphalangeal (PIP), distal interphalangeal (DIP), wrist and ankle joints, mostly in DIP2 joints [19.58%(47/240)]. Ultrasound-detected inflammatory lesions were predominantly found in metatarsophalangeal (MTP), wrist, and ankle joints, mostly in MTP2 joints (18.75%, 45/240). Clinical signs were more prevalent than ultrasound-detected inflammatory lesions in hand PIP1-3, PIP5, DIP2, and DIP5 joints ( P<0.05), whereas more frequent ultrasound-detected inflammatory lesions than clinical tenderness/swelling were in MTP1-4 joints ( P<0.05). Among ultrasound-detected inflammatory lesions, synovitis in MTP2 joints (18.75%, 45/240), tenosynovitis in ankle joints (10.00%, 24/240), enthesitis in hand DIP2 joints (8.75%, 21/240), and soft tissue inflammation in MTP4 joints (2.50%, 6/240) most commonly observed. Dactylitis was more frequently observed in toes than in fingers, with the fourth toe most commonly affected(16.67%, 40/240). Ultrasound-detected inflammatory lesions were observed in 72.37%(55/240) of fingers/toes with clinical dactylitis, mainly presenting as synovitis, tenosynovitis, or combinations of these. Conclusion:PsA exhibits significant heterogeneity in the inflammatory lesions across different joints and lesion types. The discrepancies between clinical findings and ultrasonic inflammatory changes highlight the limitations of physical examination in fully capturing the pathological features of PsA. As a critical tool for PsA evaluation, ultrasonography offers distinct advantages in detecting subclinical inflammation and differentiating inflammatory from non-inflammatory lesions.

OBJECTIVE: Baicalein has been reported to have wide therapeutic effects that act through its anti-inflammatory activity. This study examines the effect and mechanism of baicalein on sepsis-induced cardiomyopathy (SIC). METHODS: A thorough screening of a small library of natural products, comprising 100 diverse compounds, was conducted to identify the most effective drug against lipopolysaccharide (LPS)-treated H9C2 cardiomyocytes. The core target proteins and their associated signaling pathways involved in baicalein's efficacy against LPS-induced myocardial injury were predicted by network pharmacology. RESULTS: Baicalein was identified as the most potent protective agent in LPS-exposed H9C2 cardiomyocytes. It exhibited a dose-dependent inhibitory effect on cell injury and inflammation. In the LPS-induced septic mouse model, baicalein demonstrated a significant capacity to mitigate LPS-triggered myocardial deficits, inflammatory responses, and ferroptosis. Network pharmacological analysis and experimental confirmation suggested that hypoxia-inducible factor 1 subunit α (HIF1-α) is likely to be the crucial factor in mediating the impact of baicalein against LPS-induced myocardial ferroptosis and injury. By combining microRNA (miRNA) screening in LPS-treated myocardium with miRNA prediction targeting HIF1-α, we found that miR-299b-5p may serve as a regulator of HIF1-α. The reduction in miR-299b-5p levels in LPS-treated myocardium, compared to the control group, was reversed by baicalein treatment. The reverse transcription quantitative polymerase chain reaction, Western blotting, and dual-luciferase reporter gene analyses together identified HIF1-α as the target of miR-299b-5p in cardiomyocytes. CONCLUSION Baicalein mitigates SIC at the miRNA level, suggesting the therapeutic potential of it in treating SIC through the regulation of miR-299b-5p/HIF1-α/ferroptosis pathway.

Objective:To investigate the changes in and correlations between melanin-concentrating hormone (MCH) and androgen levels in the serum of patients with polycystic ovary syndrome (PCOS), aiming to provide a novel research perspective for its diagnosis.Methods:A cross-sectional study. A total of 307 subjects were enrolled from the physical examination center and endocrinology clinic of the Affiliated Hospital of Zunyi Medical University from June 2023 to June 2024. The cohort comprised 114 healthy controls and 193 patients with PCOS, diagnosed according to the Rotterdam criteria. The patients were grouped into four phenotypes: Phenotype A (hyperandrogenemia [HA]+ovulatory dysfunction [OA]+polycystic ovarian morphology [PCOM], n=44), Phenotype B (HA+OA, n=50), Phenotype C (HA+PCOM, n=46), and Phenotype D (OA+PCOM, n=53). Clinical data were collected for all subjects. Serum MCH levels were determined by enzyme-linked immunosorbent assay. The relationship between MCH and androgen-related risk factors for PCOS was analyzed using Spearman partial correlation analysis and stepwise multiple linear hierarchical regression. Binary logistic regression was used to analyze factors influencing PCOS onset. The diagnostic value of MCH for PCOS was evaluated using a receiver operating characteristic (ROC) curve. Results:There were no significant differences in age and height between the healthy control group and the PCOS phenotypic groups (both P>0.05). MCH levels [17.63 (12.69, 22.00), 17.31 (11.05, 20.09), 17.82 (11.47, 19.40), 16.50 (11.14, 19.41) μg/L vs. 12.14 (9.78, 15.05) μg/L], homeostatic model assessment of insulin resistance, fasting plasma glucose, fasting serum lisulin, body mass index, and weight were significantly higher across all four PCOS phenotypes (A, B, C, and D) than in healthy controls (all P<0.05), whereas sex hormone-binding globulin (SHBG) contents were significantly lower ( P<0.05). Free androgen index (FAI), total testosterone (TES) and dehydroepiandrosterone (DHEA) levels were significantly higher in PCOS phenotypes A, B, and C than in the control group and PCOS phenotype D (all P<0.05). Spearman partial correlation analysis revealed no significant correlation between MCH and TES, DHEA, or FAI in healthy controls and patients with non-HA PCOS (all P>0.05). However, in PCOS patients with HA, MCH showed a significant positive correlation with TES and DHEA ( r=0.227 and 0.196, respectively; both P<0.05), but not FAI ( P>0.05). Stepwise multiple linear hierarchical regression analysis showed that MCH was positively correlated with TES, DHEA and luteinizing hormone and negatively correlated with SHBG (all P<0.05). Binary logistic regression indicated that an increase in MCH may be a potential risk factor for PCOS occurrence ( OR=1.113, 95% CI 1.012-1.224, P=0.028). ROC analysis showed that MCH has diagnostic value for PCOS ( P<0.05), with an area under the curve of 0.713. Conclusion:Serum MCH is closely related to FAI, TES, and DHEA levels in PCOS patients and may play an important role in the etiology and progression of the syndrome.
