OBJECTIVE To explore the expression of Stomatin-like protein 2 (SLP-2) and its clinical significance in epithelial ovarian cancer (EOC). PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the differential expression of SLP-2 in EOC tissues and cell lines. The relationship between SLP-2 expression and clinical pathological data of EOC patients was analyzed. RESULTS QRT-PCR results suggested that the SLP-2 was up-regulated in both EOC tissues and EOC cells by comparing with normal control. SLP-2 expression was a correlation with tumor pathological grade, distant metastasis, and TNM stage in EOC patients. Down-regulation of SLP-2 could significantly inhibit proliferation and promote apoptosis of EOC cells by activating the Notch signaling pathway. Knockdown of SLP-2 markedly downregulated Notch1 and Hes1. CONCLUSIONS SLP-2 was a novel factor involved in EOC progression, and could be utilized as a potential biomarker and therapeutic target for the EOC patients.OBJECTIVE Osteosarcoma (OS) is one common bone malignant tumor prevailing in young adults and children. It is increasingly recognized microRNA 449a (miR 449a) as an anti-tumor factor in various tumours. However, little is known about the biological significance of miR 449a in OS. The intent of our study was to seek the prognostic values of miR-449a in OS. PATIENTS AND METHODS Quantitative real-time polymerase chain reaction (qRT-PCR) was performed to examine the level of miR-449a expression in 48 pairs of OS tissues and para-cancerous specimens, and the relationship between miR-449a level and clinical features of OS patient prognosis was analyzed. Moreover, we measured the miR-449a expression levels in OS cells. Transwell assay was further performed to investigate whether miR-449a influenced MG63 cell migration and invasion, which was important for malignant metastases. RESULTS Quantitative real-time polymerase chain reaction (qRT-PCR) analysis demonstrated a notable decrease of miR-449a expressions in OS. The declined miR-449a expression was relevant with the poor prognosis and malignant clinicopathologic characteristics of OS patients. Thereafter, the functional assay was performed to determine the role of miR-449a in OS progression. Results of MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assays and transwell assays indicated that miR-449a overexpression significantly repressed OS cell proliferation, invasion, and migration. Furthermore, luciferase reporter assay showed that enhancer of zeste homolog 2 (EZH2) was a downstream target of miR-449a in OS cells. Additionally, Western blot analysis demonstrated that miR-449a exerted anti-OS functions via the regulation of phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway and epithelial-mesenchymal transition. Selleck Biricodar We also indicated that miR-449a restoration could inhibit in vivo tumor growth. CONCLUSIONS These results manifested that miR-449a may thus be used as a therapeutic target in OS treatments.OBJECTIVE To investigate the relationship between the meniscal defect area and OA progression and explore the effect and mechanism of SMSCs cell therapy in knee osteoarthritis (OA) rat model. MATERIALS AND METHODS For animal experiments, knee osteoarthritis (OA) model was constructed in Sprague Dawley (SD) rats by removing the medial meniscus of the right knee. Synovial mesenchymal stem cells (SMSCs) were engrafted by injecting into the right knee cavity. For in vitro experiments, CCK-8 assay was performed to evaluate the proliferation and differentiation of BMSCs and ATDC5 cells after co-cultured with SMSCs. qRT-PCR analysis was performed to detect the expressions of chondrogenic genes in BMSCs and ATDC5 cells after co-cultured with SMSCs. Western blot analysis was conducted to detect the phosphorylations of c-Jun N-terminal kinase (JNK) and extracellular regulated protein kinases (ERK) in MAPK signaling of BMSCs and ATDC5 cells. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the serum levment.OBJECTIVE Even though in recent years significant improvements have been made in the management of patients with rheumatoid arthritis due to the introduction of biologic agents, it is still difficult to identify the most effective and safest available treatment. The choice and comparison between biological agents are a challenge, for only limited head-to-head clinical studies are available. The aim of this manuscript is to review the published network meta-analysis (NMA) to gain a better understanding of efficacy and safety of biological agents and small molecules in the management of RA patients. MATERIALS AND METHODS We used MEDLINE and EMBASE to identify network meta-analyses from 2008 to June 2019 comparing efficacy and safety of licensed biological agents and tsDMARDS at the approved dosages using predefined text words related to the topic. The following scenarios have been investigated patients not responding to csDMARD (cDMARDs - IR); csDMARD naïve patients; patients not responding to biologics (bDMARDs - IR); patients in biological monotherapy. RESULTS On the basis of the data present in the literature, we are able to hypothesize some trends of response in terms of efficacy in different subsets of patients, for example patients in monotherapy, bDMARds unresponsive patients, and Methotrexate-naive patients. The differences of the results presented in many works are due to the different inclusion criteria used in the studies, the type of biologics agent used in each study (according to the available molecules in the different years of publication), as well as differences in the methodology of NMA and in the presentation of the data. CONCLUSIONS We suggest that the next NMA follows the indications suggested by the Professional Society for Health Economics and Outcomes Research (ISPOR) so that the results are comparable and comprehensible.OBJECTIVE To explore the effect of parathyroid hormone (PTH) on the expression of Jagged1 in the rabbit tibial fracture healing, and its function and mechanism in this process via the Notch signaling pathway. MATERIALS AND METHODS A total of 60 New Zealand white rabbits were randomly divided into control group (n=30) and experimental group (n=30). Then, a rabbit tibial fracture model was established. After surgery, the rabbits in experimental group were given 10 μg/kg PTH (1-34) once a day for 5 days a week, while those in control group were given an equal volume of normal saline. Six rabbits were randomly selected from each group at 1, 2, 3, 4, and 6 weeks after surgery to collect right tibia specimens. Next, X-ray examination, bone mineral density (BMD) test, histological detection, and serum biochemical test were performed. Additionally, the messenger ribonucleic acid (mRNA) expression levels of Notch1 and Jagged1 in the Notch signaling pathway were measured via polymerase chain reaction (PCR) assay. Their protein levels were detected through Western blotting analysis. RESULTS The healing and BMD in experimental group were better than those in control group since cortical and medullary bridging was observed in the rabbits of experimental group at the 6th week after surgery. Plasma level of alkaline phosphatase (ALP), P content, and the product of Ca and P significantly increased (p less then 0.05) in experimental group. The pathological morphology of the calluses stained with hematoxylin-eosin (HE) in experimental group was overtly superior to that in control group. The PCR results revealed that both mRNA and protein levels of Notch1 and Jagged1 were lower in control group than those in experimental group (p less then 0.05). CONCLUSIONS PTH (1-34) promotes the rabbit tibial fracture healing by regulating Jagged1 ligand molecules in the Notch signaling pathway.OBJECTIVE The aim of this study was to explore the influence of micro ribonucleic acid (miR)-26b on gestational diabetes mellitus in rats via the phosphatidylinositol 3-hydroxy kinase/protein kinase B (PI3K/Akt) signaling pathway. MATERIALS AND METHODS A total of 60 healthy pregnant female rats were randomly divided into three groups, including group A (normal group), group B (model group), and group C (model + miR-26b group). The differences in fasting blood glucose (FBG), C-reactive protein (CRP), and phosphatidylinositol 3-hydroxy kinase/protein kinase B (PI3K/AKT) among the three groups were analyzed via serum CRP test, morphological observation, quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR), and Western blotting, respectively. RESULTS The levels of FBG ad CRP were significantly up-regulated in group B when compared with group A (p less then 0.01). Meanwhile, they increased significantly in group C when compared with group B (p less then 0.01). Rats in group A exhibited smooth andss then 0.01). CONCLUSIONS MiR-26b accelerates the progression of gestational diabetes by inhibiting the PI3K/Akt signaling pathway.OBJECTIVE To explore the potential correlation between endothelin 1 (EDN1) gene polymorphisms with preeclampsia (PE). PATIENTS AND METHODS The single nucleotide polymorphisms (SNPs) of 248 PE patients and 232 healthy controls were genotyped by Polymerase Chain Reaction (PCR). The possible association between EDN1 polymorphisms and PE was revealed through the t-test and the Chi-square test. RESULTS PE risk was significantly correlated with the C allele of polymorphism rs5370 in EDN1. The polymorphism rs5370 in EDN1 was remarkably associated with the onset of severe PE, rather than mild PE. The markedly increased risk of early-onset PE was related to the C allele of polymorphism rs5370 in EDN1, while no significant difference in the allele frequency of polymorphism rs1800541 was detected between the PE group and the control group. In the co-dominant model, the CC genotype of polymorphism rs5370 in EDN1 was associated with the increased PE risk. PE risk in the population carrying TC genotype was 1.59 times higher than those with TT/CC genotype, while polymorphism rs1800541 had no apparent association with PE risk. In the severe PE group, there was an evident difference in the genotype frequency between the dominant and over-dominant models of polymorphism rs5370. In the recessive model, the raised risk of early-onset PE was notably correlated with the TT/CC genotype compared with that of TT genotype. However, no evident association with the genotype frequency of polymorphism rs1800541 was observed between PE patients and controls. CONCLUSIONS EDN1 gene polymorphism rs5370 is correlated with the increased risk of PE.OBJECTIVE Lid wiper epitheliopathy (LWE) has received more attention during the diagnosis and treatment of the dry eye. However, its causes and pathogenesis remain unclear. We aimed to explore the etiology of LWE by analyzing the association between the severity of LWE and different anatomical and tissue morphological examination characteristics using confocal microscopy on eyes with dry eye syndrome. PATIENTS AND METHODS We recruited 350 patients with LWE and dry eye syndrome (350 eyes). We examined the eyes with lid-wiper staining, conjunctival staining, a comprehensive ocular surface exam using the OCULUS keratography 5M, conjunctival impression cytology, and confocal microscopy observations. We analyzed the associations between each indicator and the LWE staining score. RESULTS According to the Spearman's analysis, the LWE staining score was weakly associated with thickness of the lipid layer (r=0.1737, p=0.0005) and severity of Meibomian gland dysfunction (r=0.2026, p less then 0.0001); and strongly associated with staging of conjunctival impression cytology (r= -0.
