Hepatic alveolar echinococcosis is a highly invasive zoonotic parasitic disease with poor prognosis. Surgical intervention serves as the pivotal approach to achieve radical cure and improve the prognosis of hepatic alveolar echinococcosis patients. In recent years, with the popularization of the concept of precision surgery and the development of the multidisciplinary diagnosis and treatment model, the surgical treatment strategies for hepatic alveolar echinococcosis have been continuously enriched, and the selection of surgical procedures has become increasingly diversified. Although key surgical techniques such as radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation have achieved remarkable progress in clinical application, many insurmountable challenges still remain. Therefore, by sorting out the latest evidence-based advances in the field of surgical treatment for hepatic alveolar echinococcosis, this article focuses on discussing the application status and bottlenecks of radical hepatectomy, autologous liver transplantation and allogeneic liver transplantation in hepatic alveolar echinococcosis, aiming to provide a reference for the clinical treatment of hepatic alveolar echinococcosis.

Objective:To investigate the effects of matrix metalloproteinase 10(MMP10)on the proliferation,migration,invasion,and lymph node metastasis of oral squamous cell carcinoma(OSCC)cells,and to explore the underlying mechanisms.Methods:Gene expression profile data and survival data of head and neck squamous cell carcinoma(HNSCC)tissues and adjacent non-cancerous tissues were downloaded from The Cancer Genome Atlas(TCGA).Protein expression profile data of HNSCC tissues and adjacent non-cancerous tissues were downloaded from the Clinical Proteomic Tumor Analysis Consortium(CPTAC)database,and select the data of OSCC from HNSCC.The data from public database were used to analyze the differences in MMP10 expression at the mRNA and protein level between HNSCC/OSCC tissues and adjacent non-cancerous tissues,and to analyze the impact of MMP10 expression level on the survival rate of HNSCC patients,as well as the impact of human papillomavirus(HPV)on MMP10 gene expression in HNSCC patients.MMP10 expression level in 52 pairs of OSCC tissue samples and adjacent non-cancerous tissue samples(from the First Affiliated Hospital of Fujian Medical University)was measured by real-time quantitative PCR.After silencing MMP10 expression using siRNA(siMMP10-1291 and siMMP10-1336),the effect of MMP10 on the proliferation ability of OSCC cells was detected by CCK-8 assay and colony formation assay.The effects of MMP10 on the migration and invasion abilities of OSCC cells was assessed by wound-healing assay and transwell assay,respectively.To verify the effect of MMP10 knocking down on lymph node metastasis of OSCC cells in vivo,we constructed a nude mouse tongue cancer orthotopic model by shRNA(shMMP10-1291 and shMMP10-1336).Differential expression genes associated with MMP10 were screened from the gene expression profile data of OSCC patients in the TCGA database,and pathway enrichment analysis was performed using the GSEA software to further analyze the correlation between MMP10 and genes from the significantly enriched pathway.Results:Compared with adjacent non-cancerous tissues,the expression level of MMP10 in HNSCC and OSCC tissues was significantly increased(P<0.000 1),and HNSCC patients with high MMP10 expression had a lower survival rate(HR=1.32,P=0.04).HNSCC patients in the HPV-group had higher MMP10 gene expression levels(P<0.000 1),but their survival rate was significantly lower than that of HNSCC patients in the HPV+group(HR=0.48,P=0.004).Downregulating MMP10 expression could inhibit the migration,invasion and lymph node metastasis in vivo of OSCC cells.In OSCC patients,differentially expressed genes associated with MMP10 were significantly enriched in the Wnt signaling pathway(NES=1.505,P=0.029),and multiple genes in the Wnt signaling pathway,including WNT3,WNT3A,WNT5A,and WNT5B,were positively correlated with the expression level of MMP10.Conclusion:MMP10 promotes the invasion,metastasis and lymph node metastasis in vivo of OSCC cells by regulating the Wnt signaling pathway.

Wnt signaling are critical pathway involved in organ development, tumorigenesis, and cancer progression. WNT7A, a member of the Wnt family, remains poorly understood in terms of its role and the underlying molecular mechanisms it entails in head and neck squamous cell carcinoma (HNSCC). According to the Cancer Genome Atlas (TCGA), transcriptome sequencing data of HNSCC, the expression level of WNT7A in tumors was found to be higher than in adjacent normal tissues, which was validated using Real-time RT-PCR and immunohistochemistry. Unexpectedly, overexpression of WNT7A did not activate the canonical Wnt-β-catenin pathway in HNSCC. Instead, our findings suggested that WNT7A potentially activated the FZD7/JAK1/STAT3 signaling pathway, leading to enhanced cell proliferation, self-renewal, and resistance to apoptosis. Furthermore, in a patient-derived xenograft (PDX) tumor model, high expression of WNT7A and phosphorylated STAT3 was observed, which positively correlated with tumor progression. These findings underscore the significance of WNT7A in HNSCC progression and propose the targeting of key molecules within the FZD7/JAK1/STAT3 pathway as a promising strategy for precise treatment of HNSCC.

OBJECTIVE To compare the efficacy and safety of Cefazolin sodium for injection， Cefuroxime sodium for injection， and Ceftazidime for injection from nationally organized centralized drug procurement （hereinafter referred to as “centralized procurement”） and non-centralized procurement in patients with bacterial infection. METHODS The case data of hospitalized patients who had used 3 kinds of Cephalosporins for injection from centralized procurement or non-centralized procurement in the treatment of bacterial infections were retrospectively collected from 19 medical institutions in Kunming from January 2020 to September 2022. After balancing the baseline differences between the groups with the propensity score matching method， the effectiveness and safety differences of 3 kinds of Cephalosporins for injection from centralized procurement or non- centralized procurement were compared respectively. RESULTS After balancing the baseline differences among the groups， 394 cases in each group of Cefazolin sodium for injection from centralized procurement or non-centralized procurement， 472 cases in each group of Cefuroxime sodium for injection from centralized procurement or non-centralized procurement， 504 cases in group of Ceftazidime for injection from centralized procurement and 590 cases in group of non-centralized procurement were included in the analysis. In terms of effectiveness， there were no significant differences in clinical response rate， 72 h response rate， bacterial clearance rate， and the recovery rate of body temperature， white blood cell count， neutrophil count， neutrophil percentage， C-reactive protein， procalcitonin recovery between the centralized procurement group and non-centralized procurement group of Cefazolin sodium for injection and Cefuroxime sodium for injection （P＞0.05）. The proportion of patients in centralized procurement group of Ceftazidime for injection with C-reactive protein restored to normal reference range was significantly higher than that in non-centralized procurement group （46.9% vs. 27.9%， P＜0.05）， but there were no statistically significant differences in other effectiveness indicators among groups （P＞0.05）. In terms of safety， there was no statistical difference in the incidence of adverse drug reactions between centralized procurement group and non-centralized procurement group of 3 kinds of Cephalosporins for injection （P＞0.05）； the incidence of platelet count reduction in centralized procurement group of Cefazolin sodium for injection was significantly higher than non-centralized procurement group （20.7% vs. 7.1%， P＜0.05）， the incidence of eosinophilia elevation in centralized procurement group of Ceftazidime for injection was significantly higher than non-centralized procurement group （5.3% vs. 1.9%， P＜0.05）. In addition， there was no statistically significant difference in the abnormal rates of other laboratory indicators among the three types of injection Cephalosporins （P＞ 0.05）. CONCLUSIONS The efficacy of 3 kinds of Cephalosporin for injection from centralized procurement is not inferior to non- centralized procurement varieties， and the safety is equivalent to that of non-centralized procurement varieties.

BackgroundSibling relationships play a critical role in shaping anxiety symptoms in firstborn children. Anxiety symptoms often originate in early childhood and can persist into adolescence and adulthood. However， there is insufficient research on anxiety symptoms in preschool children， especially firstborn preschool children. ObjectiveTo explore the influencing factors of anxiety symptoms among firstborn preschool children， so as to provide references for the intervention of anxiety symptom for children in families with multiple children. MethodsFrom October to December 2021， a total of 8 449 children from 234 kindergartens in Longhua District of Shenzhen were included using a cluster sampling method. Sibling Inventory of Behavior （SIB） and Spence Preschool Anxiety Scale （SPAS） were used to investigate. Logistic regression analysis was used to identify influencing factors of anxiety symptoms in firstborn preschool children. ResultsA total of 8 419 （99.64%） valid questionnaires were collected. Anxiety symptoms were detected in 344（4.09%） firstborn preschool children. Statistically significant differences were observed between anxiety group and non-anxiety group in terms of household registration， monthly family income， maternal age， maternal education level， paternal education level， family living conditions and whether they are left-behind children （χ²/t=9.906， 33.490， 5.136， 13.485， 9.690， 17.332， 21.975， P<0.05 or 0.01）. Compared with non-anxiety group， children in the anxiety group scored higher on the SIB dimensions of rivalry， aggression and avoidance （t=165.322， 74.471， 286.419， P<0.01）， and lower on companionship， empathy and teaching （t=59.133， 42.417， 39.112， P<0.01）. Risk factors for anxiety symptoms in firstborn preschool children included left-behind children， as well as negative sibling relationships characterized by rivalry and avoidance （OR=1.195， 1.143， 1.260， P<0.05 or 0.01）. ConclusionFirstborn preschool children who are left-behind are more susceptible to anxiety symptoms. Negative sibling relationships， characterized by competition and avoidance， may also contribute to the emergence of anxiety symptoms in firstborn preschool children.
