ObjectiveTo investigate the inhibitory effect of Mahuang Xixin Fuzitang on the migration of dendritic cells (DCs) in mice and its underlying mechanism. MethodMouse bone marrow-derived DCs were isolated and cultured. The morphological changes of the cells at different stages were observed under a microscope, and the CD11c+ proportion was detected by flow cytometry to identify DC purity. Cells were treated with Mahuang Xixin Fuzitang (1, 2, 5, 10, 20, 40, 50, 100 g·L-1) for 24 hours, and the effect of Mahuang Xixin Fuzitang on cell proliferation was assessed using the cell counting kit-8 (CCK-8) assay to determine the appropriate concentrations for treatment. After modeling by lipopolysaccharide (LPS) induction, DCs were divided into a blank group, a model group, and Mahuang Xixin Fuzitang groups (2, 4, 8 g·L-1). The expression of surface molecules CD80, CD86, and major histocompatibility complex-Ⅱ (MHC-Ⅱ) were detected by flow cytometry. Transwell chamber assay was used to observe cell migration. The levels of chemokine C-C-primitive receptor 7 (CCR7) and chemokine C-X-C-primitive receptor 4 (CXCR4) on the cell surface were detected by enzyme-linked immunosorbent assay (ELISA). The expression of filamentous actin (F-actin) in the cell microfilament cytoskeleton was detected by immunofluorescence (IF) staining. Real-time quantitative polymerase chain reaction (Real-time PCR) was employed to determine the mRNA expression levels of Ras homolog family member A (RhoA) and Rho-associated coiled-coil containing protein kinase 1 (ROCK1). Western blot analysis was performed to detect the protein expression of RhoA and ROCK1. ResultCompared with the blank group, the model group exhibited significantly higher expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly increased number of cells migrating to the lower chamber (P<0.01), and significantly elevated levels of CCR7 and CXCR4 (P<0.05, P<0.01). Additionally, F-actin expression was significantly increased (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly higher (P<0.05, P<0.01). Compared with the model group, treatment with Mahuang Xixin Fuzitang (2, 4, 8 g·L-1) for 24 hours resulted in significantly lower expression levels of CD80, CD86, and MHC-Ⅱ (P<0.01), a significantly reduced number of cells migrating to the lower chamber (P<0.05), and significantly decreased levels of CCR7 and CXCR4 (P<0.05, P<0.01). Furthermore, F-actin expression was significantly reduced (P<0.01), and both RhoA and ROCK1 mRNA and protein expression levels were significantly decreased (P<0.05, P<0.01). ConclusionMahuang Xixin Fuzitang can inhibit the migration of DCs in mice, and its mechanism of action may be related to reducing the activity of the Rho/ROCK signaling pathway, thereby affecting changes in the cell cytoskeleton.

【Objective】 To explore the safety and efficacy of a novel endoscopic two-wire guided dilation in the creation of channels in percutaneous nephrolithotomy (PCNL). 【Methods】 Clinical records of 180 patients undergoing PCNL during Oct.2020 and Oct.2022 were retrospectively analyzed. The patients were divided into three groups, 60 in AMD group (fascial amplatz dilation), 60 in OSD group (one shot dilation) and 60 in END group (endoscopic dilation). Time to establish channels, operating time, failure of access, stone clearance rate, drop in hemoglobin, embolization rate, fever rate, blood transfusion rate and postoperative hospitalization were compared among the three groups. 【Results】 There were no significant differences in the general data among the three groups (P>0.05). Compared with AMD and OSD groups, END group needed significantly reduced time to establish the first channel [(5.6±0.8) min vs. (4.9±1.4) min vs. (4.2±0.5) min, (P<0.05)] . Compared with OSD group, END and AMD groups had significantly more hemoglobin drop [(14.0±17.6) g/L vs. (19.4±12.6) g/L vs. (10.2±6.8) g/L, (P<0.05)] . There were no significant differences in terms of failure of establishing channels, operating time, stone clearance rate, embolization rate, fever rate, blood transfusion rate and postoperative hospitality. Four patients needed selective renal artery embolization (1 case in AMD group and 3 in OSD group). No serious complications such as organ injuries, septic shock or death occurred. 【Conclusion】 Endoscopic two-wire guided dilation is simple, with few complications and good application value.

Objective:To investigate the correlations of laminin subunit gamma 3 (LAMC3) expression with prognosis of ovarian cancer (OC).Methods:LAMC3 protein expression was measured using immunohistochemical streptavidin-peroxidase-biotin connection method (IHC). Gene expression and related clinical data in the cancer genome atlas (TCGA) cohort and clinical proteomic tumor analysis consortium (CPTAC) were applied to analyse the correlation between gene and protein expressions and clinical outcomes. Correlations between LAMC3 and clinicopathological factors were evaluated using the Pearson χ2 test (2-sided). The probability of survival and significance was calculated using the Kaplan-Meier plot. The functional clustering of biological pathways enriched from co-expressed genes of LAMC3 was used to explore the possible mechanisms that LAMC3 might contribute to poor prognosis. Results:Based on the IHC results of 216 OC tissues or ovaries (including 208 tumors and 8 normal tissues) and 51 OC tissues (including 24 chemotherapy-resistant and 27 sensitive tissues), and the protein expression data from CPTAC (including 100 primary tumors and 25 normal tissues), the results showed that the protein expression of LAMC3 was significantly decreased in OC tissues compared with normal, decreased in advanced-stage tissues compared with early-stage tissues, and decreased in drug-resistant tissues compared with sensitive tissues (all P<0.05). Furthermore, low expression of LAMC3 protein was significantly associated with poor disease-free survival (DFS) and overall survival (OS) in 51 OC tissues ( P<0.01), consistent with the results that the low levels of LAMC3 mRNA predicted short DFS and OS in 489 OC tissues of the TCGA cohort ( P<0.05). The results suggested that low expression of LAMC3 might be the adverse factors for OC development, such as drug resistance and advanced tumors, and might be a risk indicator for prognosis. Moreover, functional clustering of biological pathways enriched from the co-expressed genes of LAMC3 in TCGA ovarian cohort indicated that LAMC3 potentially involved in regulation of OC via oncogene-pathways such as Ras associated protein 1 (Rap1), mitogen-activated protein kinase (MAPK), Ras and cell adhesion-related pathways such as extra cellular matrix (ECM)-receptor interaction and focal adhesion. It indicated that LAMC3 might contribute to short survival and tumor progression by regulation of the above pathways. Conclusion:Low expression of LAMC3 is related to poor prognosis and malignant progression in OC, and thus it is expected to be a new prognostic marker and therapeutic target for clinical treatment.
