Hypochlorous acid (HClO/HOCl) is a reactive oxygen species closely associated with immune defense and oxidative stress-related pathology, creating demand for fast and convenient analytical tools for its detection in environmental and biological matrices. Herein, a coumarin-derived fluorescent probe (XDS) was synthesized by condensing a coumarin aldehyde with a benzothiazolium salt. XDS exhibited an obvious color change (purple to colorless) and a turn-on fluorescence response toward HClO in a DMSO/PBS (3 : 7, v/v, pH 7.4) system. Under optimized conditions, XDS exhibited high selectivity against common anions, biothiols, and several reactive oxygen/nitrogen species, and reached its fluorescence plateau within ∼15 s after HClO addition. The probe was further integrated into a solid support format by loading it onto silica gel plates, enabling visual readout for HClO-spiked tap water, stream water, and mineral water samples. In addition, XDS was applied to fluorescence imaging of exogenous HClO in HepG2 cells and to adult zebrafish imaging following chemical stimulation. These results support the potential of XDS as a rapid dual-mode (colorimetric/fluorescent) platform for HClO sensing in aqueous samples and biological systems.
Osteoporosis (OP) is an epidemic bone remodeling disorder of growing relevance with the aging population. Considering that isorhamnetin (ISO), a flavonoid derived from plant, has been newly reckoned as an active ingredient in treating OP, our paper was conducted to investigate the regulatory role and mechanism of ISO in OP. CCK-8 method detected cell activity. Alkaline phosphatase (ALP) assay kit, ALP staining and alizarin red S staining measured osteogenic differentiation. RT-qPCR and Western blot examined the expressions of osteoblast-related proteins. Wound healing and cell adhesion assays severally detected cell migration and adhesion. Also, Western blot tested the expressions of extracellular signal-regulated kinase (ERK) signaling-associated proteins. As illustrated, after MC3T3-E1 pre-osteoblasts were stimulated to differentiate to osteoblasts, ISO markedly promoted the differentiation, mineralization, migration and adhesion of MC3T3-E1 osteoblasts in a concentration-dependent manner. In addition, administration of ISO functioned as an activator of ERK-dependent BMP2-Smad signaling in MC3T3-E1 osteoblasts and pretreatment with ERK inhibitor PD98059 partially compensated the impacts of ISO on MC3T3-E1 osteoblasts differentiation, mineralization, migration as well as adhesion. To be summarized, ISO might activate ERK-dependent BMP2-Smad signaling to facilitate the differentiation, mineralization, migration and adhesion of MC3T3-E1 osteoblasts, suggesting the protective potential of ISO in OP.
Objective:To preliminarily evaluate the clinical efficacy and safety of stereotactic body radiotherapy (SBRT) for pulmonary oligometastatic tumors.Methods:A retrospective analysis was performed on 46 patients treated with SBRT for pulmonary oligometastatic tumors from Jan 2017 to May 2018. There were 36 cases with primary pulmonary oligometastasis, 10 cases with secondary pulmonary oligometastasis. The pathological type included 31 cases of adenocarcinoma, 12 cases of squamous cell carcinoma and 3 cases of others. Dosage regimen was designed as 6 MV X-ray, 48-60 Gy/4-8fx. The Kaplan-Meier method was used to analyze the overall survival (OS) rates of 1 and 2 years. The Spearman method was used to analyze the correlation between the prescription dose pattern, target volume, whole lungs dose and the incidence of acute radiation pneumonitis (ARP), respectively. Results:The median follow-up time was 15.5 months. OS of 1 and 2 years were 65% and 37%, respectively. There were 27 cases with grade 1 ARP (59%), 16 cases with grade 2 (35%), 3 cases with grade 3 (7%), none of grade 4 ARP. The grade of ARP was related to the dose pattern of prescription and the planning target volume ( P<0.05). Grade 2 ARP was related with whole lungs V5 ( P<0.05). Conclusions:SBRT was safe and effective in the treatment of pulmonary oligometastases. The dose pattern of prescription, planning target volume and double lung V5 were closely related to the occurrence of ARP and may become important predictors.

ETHNOPHARMACOLOGICAL RELEVANCE:Weishi Huogu I (WH I) capsules, developed through traditional Chinese medicine, have been used to treat clinical osteonecrosis of the femoral head (ONFH) for decades. However, the mechanisms have not been systematically studied.AIM OF THE STUDY:In this study, the mechanisms of WH I capsules used in treating ONFH were examined through a systems pharmacology strategy, and one mechanism was validated with in vitro experiments.MATERIALS AND METHODS:WH I capsules compounds were identified by screening databases; then, a database of the potential active compounds was constructed after absorption, distribution, metabolism and excretion (ADME) evaluation. The compounds were identified through a systematic approach in which the probability of an interaction of every candidate compound with each corresponding target in the DrugBank database was calculated. Gene Ontology (GO) and pathway enrichment analyses of the targets was performed with the Metascape and KEGG DISEASE databases. Then, a compound-target network (C-T) and target-pathway network (T-P) of WH I capsule components were constructed, and network characteristics and related information were used for systematically identifying WH I capsule multicomponent-target interactions. Furthermore, the effects of WH I capsule compounds identified through the systematic pharmacology analysis of the osteogenic transformation of human umbilical mesenchymal stem cells (HUMSCs) were validated in vitro.RESULTS:In total, 152 potentially important compounds and 176 associated targets were identified. Twenty-two crucial GO biological process (BP) or pathways were related to ONFH, mainly in regulatory modules regulating blood circulation, modulating growth, and affecting pathological processes closely related to ONFH. Furthermore, the GO enrichment analysis showed that corydine, isorhamnetin, and bicuculline were enriched in "RUNX2 regulates osteoblast differentiation", significantly increased alkaline phosphatase activity and calcium deposition and upregulated runt-related transcription factor 2 mRNA and protein expression and osteocalcin mRNA expression in HUMSCs, suggesting that these compounds promoted the mesenchymal stem cell (MSC) osteogenic transformation.CONCLUSIONS:The study showed that the pharmacological mechanisms of WH I capsule attenuation of ONFH mainly involve three therapeutic modules: blood circulation, modulating growth, and regulating pathological processes. The crosstalk between GOBPs/pathways may constitute the basis of the synergistic effects of the compounds in WH I capsules in attenuating ONFH. One of the pharmacological mechanisms in the WH I capsule effect on ONFH involves enhancement of the osteogenic transformation of MSCs, as validated in experiments performed in vitro; however, more mechanisms should be validated in further studies.

Background Cell division cycle 6 (CDC6) has been proven to be associated with the initiation and progression of human multiple tumors. However, it’s role in glioma, which is ranked as one of the common primary malignant tumor in the central nervous system and is associated with high morbidity and mortality, is unclear. Methods In this study, we explored CDC6 gene expression level in pan-cancer. Furthermore, we focused on the relationships between CDC6 expression, its prognostic value, potential biological functions, and immune infiltrates in glioma patients. We also performed vitro experiments to assess the effect of CDC6 expression on proliferative, apoptotic, migrant and invasive abilities of glioma cells. Results As a result, CDC6 expression was upregulated in multiple types of cancer, including glioma. Moreover, high expression of CDC6 was significantly associated with age, IDH status, 1p/19q codeletion status, WHO grade and histological type in glioma (all p < 0.05). Meanwhile, high CDC6 expression was associated with poor overall survival (OS) in glioma patients, especially in different clinical subgroups. Furthermore, a univariate Cox analysis showed that high CDC6 expression was correlated with poor OS in glioma patients. Functional enrichment analysis indicated that CDC6 was mainly involved in pathways related to DNA transcription and cytokine activity, and Gene Set Enrichment Analysis (GSEA) revealed that MAPK pathway, P53 pathway and NF-κB pathway in cancer were differentially enriched in glioma patients with high CDC6 expression. Single-sample gene set enrichment analysis (ssGSEA) showed CDC6 expression in glioma was positively correlated with Th2 cells, Macrophages and Eosinophils, and negative correlations with plasmacytoid dendritic cells, CD8 T cells and NK CD56bright cells, suggesting its role in regulating tumor immunity. Finally, CCK8 assay, flow cytometry and transwell assays showed that silencing CDC6 could significantly inhibit proliferation, migration, invasion, and promoted apoptosis of U87 cells and U251 cells ( p < 0.05). Conclusion In conclusion, high CDC6 expression may serve as a promising biomarker for prognosis and correlated with immune infiltrates, presenting to be a potential immune therapy target in glioma.

Objective:To investigate the expression and clinical significance of long non coding RNA LINC01614 in non-small cell lung cancer (NSCLC).Methods:From January 2016 to December 2017, 75 patients with primary NSCLC who underwent surgical resection in our hospital were selected as the cases, and the corresponding adjacent tissues (more than 5 from the tumor edge) were selected as control.The correlation between LINC01614 expression and clinicopathological characteristics of NSCLC patients was analyzed.ROC curve was drawn to determine the efficacy parameters of LINC01614 in the diagnosis of NSCLC.Kaplan Meier curve was used to analyze the survival analysis.Results:The expression levels of 3 261 lncRNAs were significantly different in NSCLC patients, including 1 205 up-regulated and 2 056 down-regulated.At the same time, LINC01614 was the most disordered lncRNA, and its expression was up-regulated in cancer tissues, 22.92 times higher than that in paracancerous tissues.The higher the TNM stage, the lower the degree of tissue differentiation and the occurrence of lymph node metastasis, the higher the relative expression of LINC01614.The area under the ROC curve was 0.788 (95% CI: 0.710-0.821), with a diagnostic sensitivity of 58.62% and a specificity of 87.24%.With the relative expression of LINC01614 of 26.14 as the intercept, the overall survival of NSCLC patients in the high expression group (26 cases) and the low expression group (49 cases) was 22.2 months (95% CI: 20.1-34.6) and 38.5 months (95% CI: 25.3-45.5), respectively.The survival time of the high expression group was significantly lower than that of the low expression group ( Z=10.248, P<0.05). Multivariate COX proportional hazards stepwise regression analysis showed that LINC01614 overexpression was an independent prognostic factor for NSCLC patients ( HR=2.25, 95% CI: 1.30-3.90). Conclusions:LINC01614 is highly expressed in NSCLC tissues, and is related to the malignant degree of NSCLC, which may have a certain guiding significance for the prognosis of NSCLC.
