Objective:To investigate the microRNA (miRNA) expression features in ectopic endometrial tissues of endometriosis (EMS) patients.Methods:From April 2018 to October 2019, ectopic endometrial tissues from EMS patients and eutopic endometrial tissues from control women who received treatment in the Department of Obstetrics and Gynecology of The First Affiliated Hospital of Xiamen University were used in subsequent experiments. Differentially expressed miRNAs were screened out in ectopic endometrial tissues by detecting miRNA sequence from Illumina. The potential roles of these differentially expressed miRNAs and their potential targeted genes in pathogenesis of EMS were analyzed by bioinformatics, and the differential expression levels of 6 miRNAs (miR-98-5p, miR-495-3p, let-7c-5p, miR-200b-3p, miR-200c-3p, miR-148b-3p) were validated by quantitative real-time polymerase chain reaction (qRT-PCR) and subsequently used to build the miRNA-gene regulatory network, then we verified its potential target gene.Results:The microarray results showed that 69 miRNAs might be differentially expressed in ectopic endometrial tissues compared with those in eutopic endometrial tissues (fold change>1.5, P<0.05), including 22 up-regulated miRNAs and 47 down-regulated miRNAs. Gene ontology (GO) analysis showed that the target genes of these differentially expressed miRNAs mainly participated in the protein modification, regulation of development, cell metabolism and morphological structure. KEGG pathway analysis showed that these targeted genes were involved in protein function, autophagy, AGE-RAGE and MAPK signaling pathways. The expression levels of miR-98-5p, let-7c-5p, miR-200b-3p and miR-200c-3p were validated to be significantly altered in ectopic endometrial tissues. The miRNA-gene co-expression network revealed the correlation between the 4 miRNAs and their predicted target genes. qRT-PCR validated results showed that the expression of miR-200b-3p and miR-200c-3p were significantly negatively correlated with ZEB2, while miR-98-5p was negatively correlated with PGRMC1, miR-98-5p and let-7c-5p were positively correlated with ADIPOR2. Conclusion:MiR-98-5p, let-7c-5p, miR-200b-3p and miR-200c-3p were significantly differentially expressed in the ectopic endometrial tissues of EMS patients, which may be involved in the development of EMS.

Objective: To explore the treatment effects of edaravone combined with antiviral drugs on 30 adult cases with viral encephalitis. Methods: Sixty adult patients with viral encephalitis in our hospital were selected for the study and were divided into control group and observation group according to the admission number, with 30 cases in each group. Control group was treated with conventional antiviral drugs, and observation group was given antiviral drugs combined with edaravone. Another 30 healthy people admitted to the hospital in the same period for physical examination were included in healthy group. The clinical efficacy and time to normalization of clinical manifestations (fever, headache, vomiting, EEG abnormalities) were recorded in observation group and control group, and the oxidative stress indicators [catalase (CAT), lipids peroxide (LPO)] and nerve injury indexes [neuron-specific enolase (NSE), glial fibrillary acidic protein (GFAP)] were compared between observation group, control group and healthy group before treatment and after 2 weeks of treatment. The neurological deficit [National Institutes of Health Stroke Scale (NIHSS)] was observed in observation group and control group. Results: The clinical efficacy in observation group was significantly better than that in control group (P<0.05), and the normal recovery times of fever, headache, vomiting and abnormal EEG were lower than those in control group (P<0.05). After 2 weeks of treatment, the partial oxidative stress index (serum CAT) in observation group and control group was higher than that before treatment (P<0.05) while partial oxidative stress index (serum LPO), nerve injury indexes (serum NSE, GFAP) and neurological defect (NIHSS score) were lower than those before treatment (P<0.05), and the changes in observation group were greater than those in control group (P<0.05). The serum CAT levels in the two groups before and after treatment were lower than those in healthy group (P<0.05), and the levels of LPO, NSE and GFAP were higher than those in healthy group (P<0.05). Conclusions Edaravone combined with antiviral drugs has significant treatment effects in the treatment of adult viral encephalitis. It can not only reduce the body’ s oxidative stress response, but also reduce nerve injury and improve neurological deficit, and it has a certain application value.

Proteomic analysis of core needle biopsy (CNB) sample from patient populations is critical to our understanding of human disease,but has been hindered by its particular small size.Here,we present a method for the proteomic analysis of CNB sample based on the two dimensional electrophoresis.Proteins were extracted directly from 3 rat liver CNB specimens and a human prostate CNB sample.respectively.24 cm Immobiline DryStrip (pH 3-10NL) and 12.5% SDS-PAGE were introduced to separate the proteins.Interesting spots were analyzed by MALDI TOF/TOF mass spectrometry after tryptic digestion.With this method,consistent electrophoretic patterns of more than 2 500 protein spots were reproducibly obtained after silver staining,from rat liver CNB specimens.Qualitatively and quantitatively reproducible results also yield when the method was applied to a human prostate CNB sample.57 stochastically selected protein spots were analyzed by MALDI TOF/TOF moss spectrometry.and were identified with high confidence including faint ones.This simple and reproducible approach raises the opportunity of defining key molecular events of human disease pathologies.
