Objective To predict the target genes and function of has-miR-26b,has-miR-1972,has-miR4485,has-miR-4498,and has-miR-4743 by bioinformatics analysis,and provide the theoretical basis for the further research.Methods The targets of the five microRNAs were predicted by Target Scan,miRBD,and DIANA-microT-CDS,and the result were analyzed by gene ontology and pathway analysis using FunNet.Results 734 predicted targets were obtained by finding the intersected genes of Target Scan,miRBD,and DIANA-microT-CDS.GO analysis showed that biological processes regulated by the differentially expressed microRNAs included diverse terms,among which some terms (e.g.,central nervous system development,neuron differentiation,axonogenesis,synaptic transmission,learning,and memory,etc.) had direct relationship with the central nervous system and brain functions.The pathway analysis showed that a significant enrichment in several pathways related to neuronal brain function,such as axon guidance,glutamatergic synapse,Wnt signaling pathway,mTOR signaling pathway,VEGF signaling pathway,etc.Among the five microRNAs,has-miR-26b,has-miR-1972,has-miR-4498 might have more important regulatory functions.Conclusion Bioinformatic analysis indicates that has-miR-26b,has-miR-1972,has-miR-4485,has-miR-4498,and has-miR-4743 are closely related to the mechanism and pathogenesis of major depressive disorder.

Objective To investigate the diagnostic value of microRNA (miRNA) in peripheral venous blood for depressive disorder.Methods Real-time fluorescence quantitative PCR (RT-qPCR) was used to verify expression level of miRNAs in peripheral blood of non-specific mental retardation children,which were aberrantly expressed in depressive disorder patients,and then Receiver Operating Characteristics (ROC)curve was employed to confirm the sensitivity and specificity of abnormal miRNA expression in depressive disorder and non-specific mental retardation.Results MiR-1972,miR-26b,miR-4485,miR-4498 and miR-4743 were upregulated significantly in case group of depressive disorder(P＜0.05),meanwhile miR-4485 and miR-4743 in aforementioned 5 miRNAs also upregulated significandy in patients of non-specific mental retardation(P＜0.05),but miR-26b showed no significant difference between case group of non-specific mental retardation and the control group (P＞0.05).The ROC curve of miR-26b in depressive disorder patients and their control group showed that the sensitivity and specificity were 0.609,0.664 respectively,and the area square under the curve was 0.614(P=0.021).The ROC curve of miR-26b in patients of depressive disorder and non-specific mental retardation indicated that the sensitivity and specificity were 0.784 and 0.471,and area square under the curve was 0.643 (P=0.003).Conclusion miR-26b probably have diagnostic value for depressive disorder,which may comorbidity with non-specific mental retardation.But genetic and psychosocial mechanism of comorbidity still needs further exploration.

Objective To observe the effects of triptolide(TPL) on the anti-oncogene-APC gene of acute lymphoblastic leukemia cell line Jurkat in vitro. Methods The effects of TPL on proliferation Jurkat cells were assayed by using cell culture, MTT. The effects of TPL on APC gene of Jurkat cells were analyzed by nested methylation specific PCR and RT-PCR. The effects of TPL on the proteinum expression of APC gene were detected by Western blotting analysis. Results Following the treatment of TPL, the cell proliferation rate was degraded as the treatment concentration increased and the culture time extended. The effects were dose and time-dependent. The 48 hour IC50 was 19.7 ng/ml. TPL can reverse hypermethylation of APC gene,and induce the expression of the mRNA and the proteinum. Conclusion Low dose TPL could depress the proliferation rate of Jurkat. The possible mechanism might be its reversing the hypermethylation of APC gene and activiting the expression of APC gene.

Objective To investigate the clinical effect of improved portable mirabilite bag by abdominal application in the treatment of severe acute pancreatitis. Methods A total of 50 patients with severe acute pancreatitis admitted to our hospital from May2015 to January 2016 were enrolled as the control group, which was treated with traditional self-made towel bag filled with mirabilite for the abdominal application. Another 50 patients with severe acute pancreas hospitalized in our hospital from February 2016 to April 201750 patients as the experimental group, which was treated with improved portable mirabilite bag by abdominal application. The two groups were compared in terms of contamination by clothing, shedding, dislocation, aggregation, abdominal pain, bloating, and recovery time of gastrointestinal function. Results The incidences of shedding and displacement of mirabilite bag, mirabilite accumulation and contamination in the experimental group were lower than those of the control group. The abdominal distension time and bowel sound recovery time were significantly shorter than that in the control group (P ＜0.05, P ＜0.001). Conclusions By the improved portable mirabilite bag, the mirabilite can be evenly applied to the external abdomen of the patients. It is simple to make the bag and convenient for the clinical use, worthy of clinical application.

Objective:To explore the role of interleukin (IL)-9 and other T helper (Th) cell-related cytokines in the pathogenesis of acute anterior uveitis.Methods:A cross-sectional study was conducted.Thirty-six patients (36 eyes) with acute anterior uveitis who were treated at Gansu Provincial Hospital from May 2018 to May 2019 and 40 matched healthy subjects (40 eyes) who had no eye diseases or systemic diseases in the same period were enrolled as the acute anterior uveitis group and healthy control group, respectively.The disease severity of the subjects in the acute anterior uveitis group was graded and the subjects were divided into mild, moderate and severe groups according to the grading.Serum of all subjects was collected to determine the concentration of serum IL-9, IL-17, transforming growth factor-β 1 (TGF-β 1), interferon-γ (IFN-γ), IL-4, IL-35 and IL-22 by enzyme linked immunosorbent assay (ELISA) method.Spearman rank correlation analysis was used to evaluate the relationship between IL-9 concentration and other Th cell-related cytokines.This study adhered to the Declaration of Helsinki.The study protocol was approved by an Ethics Committee of Gansu Provincial Hospital (No.2019-204). Written informed consent was obtained from each subject prior to any medical examination. Results:The serum levels of IL-9, IFN-γ, IL-4, TGF-β 1, IL-35 and IL-22 in the acute anterior uveitis group were significantly higher than those in the healthy control group, and the differences were statistically significant (all at P<0.05). There was no statistically significant difference in the concentration of IL-17 between the two groups ( U=704.500, P=0.872). The IL-9 concentration of patients with acute anterior uveitis in the mild, moderate and severe groups was 57.24 (47.47, 65.10), 71.68 (67.55, 78.91) and 114.01 (74.78, 139.30) ng/L, respectively, and the overall difference was statistically significant ( Z=8.766, P=0.012), and the IL-9 concentration of the mild group and the moderate group was significantly lower than that of the severe group (both at P<0.05). The concentration of IL-9 in the patients with acute anterior uveitis was positively correlated with the concentration of IL-17, TGF-β 1 and IL-35 ( rs=0.449, 0.517, 0.400; all at P<0.05), and no significant correlations were found between the concentration of IL-9 and the concentration of IFN-γ, IL-4 and IL-22 ( rs=0.293, 0.286, 0.316; all at P>0.05). Conclusions:IL-9 plays a role in promoting the immune inflammatory response in the occurrence and development of acute anterior uveitis, and it is closely related to Th17 and Treg cell-related cytokines (TGF-β 1, IL-35).

OBJECTIVE To identify differentially expressed microRNA (miRNA) in peripheral blood mononuclear cells (PBMCs) of anxiety patients and predict their target genes and function by bioinformatics analysis. METHODS The miRNA expression profiles were determined using an Affymetrix array. To validate the results, real-time quantitative polymerase chain reaction (qRT-PCR) analysis in a larger cohort was employed. The targets of the differentially expressed miRNAs were predicted by Target Scan, miRBD, and DIANA-microT-CDS, and the results were analyzed by gene ontology (GO) and KEGG pathway analysis using FunNet. RESULTS MicroRNA microarray chip analysis has identified 7 miRNAs were detected with significant changes in expression in PBMCs of anxiety patients. qRT-PCR analysis has confirmed that the expression levels of 5 miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) were up-regulated. Intersecting the genes by Target Scan, miRBD, and DIANA-microT-CDS has predicted 195 targets. GO analysis showed that biological processes regulated by the predicted target genes have included diverse terms. Some terms, e.g., nervous system development, nerve growth factor receptor signaling pathway, neuron migration, dendrite development, regulation of neuron projection development, midbrain development, regulation of excitatory postsynaptic membrane potential, gliogenesis, dendrite morphogenesis, etc. have direct relationship with the central nervous system and brain functions. Pathway analysis showed that a significant enrichment in several pathways related to neuronal brain functions such as glutamatergic synapse, axon guidance, calcium signaling pathway, MAPK signaling pathway, GnRH signaling pathway, Wnt signaling pathway, gap junction, long-term potentiation and VEGF signaling pathway, etc. Among the five microRNAs, has-miR-4484, has-miR-4505, has-miR-4674 and has-miR-501-3p may have more important regulatory functions. CONCLUSION Five miRNAs (has-miR-4484, has-miR-4505, has-miR-4674, has-miR-501-3p and has-miR-663) are up-regulated in PBMCs of anxiety patients and may be closely involved in the pathogenesis of anxiety disorder.

Objective:To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT).Methods:A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ 2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results:A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment.Conclusion:ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.
