Objective:To explore the expression of microRNA-3162-3p in different clinical stages of childhood primary immune thrombocytopenia(ITP)and its significance.Methods:Ninety-six children with ITP were enrolled and divided into new diagnosis group(n=40),persistent group(n=30)and chronic group(n=26)according to the course of disease.80 healthy children were selected as the control group.Peripheral blood mononuclear cells(PBMNC)of ITP children and healthy children were isolated and cultured,and the expression of microRNA-3162-3p in PBMNC of subjects was detected by real-time fluorescence quantitative PCR.The contents of IL-17,IL-23,IL-10 and TGF-β in PBMNC of subjects were determined by ELISA.The correlation between microRNA-3162-3p and platelet count,IL-17,IL-23,IL-10 and TGF-β was analyzed.Results:Compared with the control group,the expression of microRNA-3162-3p and IL-10 in PBMNC and platelet count of ITP children were significantly decreased(P＜0.05),while IL-17,IL-23 and TGF-β were significantly increased(P＜0.05).With the prolongation of the disease course,the expressions of microRNA-3162-3p and IL-10 in PBMNC and platelet count were significantly decreased(P＜0.05),while the expressions of IL-17,IL-23 and TGF-β were significantly increased(P＜0.05).The expression of microRNA-3162-3p in PBMNC was positively correlated with platelet count and IL-10(r=0.716,0.667),and negatively correlated with IL-17,IL-23,and TGF-β(r=-0.540,-0.641,-0.560).Conclusion:MicroRNA-3162-3p expression is significantly reduced in PBMNC of children with ITP,and is involved in the regulation of Th17/Treg imbalance,which can be used as a potential therapeutic target of ITP.

Objective:To observe the effects of transcranial direct current stimulation (tDCS) on the naming of visual and auditory modality in patients with post-stroke aphasia. Methods:From March to November, 2018, 32 patients with post-stroke aphasia were randomly divided into control group (n = 16) and treatment group (n = 16). The treatment group accepted anodal-tDCS (A-tDCS) over left-inferior frontal gyrus (L-IFG) concurrent with speech training, while the control group accepted sham-tDCS. Before and two weeks after treatment, they were assessed with Western Aphasia Battery (WAB), Picture Naming Test and Environmental Sound Naming Test. Results:One patient was lost in the control group. After treatment, Aphasia Quotient of WAB improved in both groups (t > 5.081, P < 0.001), but the difference before and after treatment was not significantly different between two groups (t = 1.550, P > 0.05); the Picture Naming Test score improved in both groups (Z > 2.650, P < 0.01), and the difference before and after treatment was more in the treatment group than in the control group (Z = -2.258, P < 0.05); the object naming score of WAB improved in the treatment group (Z = -3.239, P < 0.01), and the difference before and after treatment was more in the treatment group than in the control group (Z = -3.008, P < 0.01); the score of Environment Sound Naming Test improved in the treatment group (t = -4.745, P < 0.001), and the difference before and after treatment was more in the treatment group than in the control group (t = 2.224, P < 0.05). The scores of spontaneous naming, sentences complement and reaction naming of WAB improved in the treatment group (Z > 2.191, P < 0.05), while the score of spontaneous naming of WAB improved in the control group (Z = -2.376, P < 0.05), but the differences before and after treatment were not significantly different between two groups (Z < 1.568, P > 0.05). Conclusion:A-tDCS over L-IFG may improve the naming ability of visual and auditory modality, which may associate with semantic or phonetic processing.

Objective The main cause of systemic inflammatory response syndrome(SIRS) after percutaneous nephrolithotomy(PCNL) was still unclear. The purpose of this study was to investigate the risk factors associated with SIRS after PCNL and establish the nomogram model. Methods A retrospective analysis of 213 cases of PCNL patients due to upper urinary calculi admitted to urology department in affiliated hospital of guilin medical college from December 2017 to December 2018 was performed. According to the occurrence of SIRS, patients were divided into SIRS group (SIRS patients) and control group (patients without SIRS). Logistic regression was used to analyze the risk factors of SIRS after PCNL, and a nomogram model was established based on logistic regression model. Results There were 54 cases in the SIRS group and 159 in the control group. Gender(OR=2.547, 95%cl:1.229-5.275), diabetes (OR=5.027, 95%cl: 1.442-17.525), calculi surface area (OR=2.657, 95%cl: 1.206-5.853), NLR immediately after surgery (OR=3.793, 95%cl: 1.749-8.02), operation time (OR=2.985, 95%cl: 1.305-6.826), and blood transfusion (OR=12.50, 95%cl: 12.50). 1.954-80.056) were the risk factors of SIRS after PCNL (P<0.05). Based on the results of the logistic multi-factor regression model mentioned above, visualized display of the model was achieved by using column and diagram. As the NLR ratio, operation time and stone surface area increased immediately after the operation, the score gradually increased, and the risk of SIRS gradually increased. The nomogram model established according to logistic regression model has good differentiation and model consistency (c-index =0.791). Conclusion According to the risk factors, such as gender, diabetes history, stone surface area, immediate postoperative NLR, the constructed nomogram model has good predictive efficacy, which is of guiding significance for clinical practice.

OBJECTIVE: To investigate the effect of phorbol-12-myristate-13-ace-tate (TPA) on the proliferation and apoptosis of acute promyelocytic leukemia cell line NB4 and its molecular mechanism. METHODS: The effect of different concentrations of TPA on the proliferation of NB4 cells at different time points was detected by CCK-8 assay. The morphological changes of NB4 cells were observed by Wright-Giemsa staining. The cell cycle and apoptosis of NB4 cells after TPA treatment were detected by flow cytometry. The mRNA expressions of NB4 cells after TPA treatment were analyzed by high-throughput microarray analysis and real-time quantitative PCR. Western blot was used to detect the protein expression of CDKN1A, CDKN1B, CCND1, MYC, Bax, Bcl-2, c-Caspase 3, c-Caspase 9, PIK3R6, AKT and p-AKT. RESULTS: Compared with the control group, TPA could inhibit the proliferation of NB4 cells, induce the cells to become mature granulocyte-monocyte differentiation, and also induce cell G₁ phase arrest and apoptosis. Differentially expressed mRNAs were significantly enriched in PI3K/AKT pathway. TPA treatment could increase the mRNA levels of CCND1, CCNA1, and CDKN1A, while decrease the mRNA level of MYC. It could also up-regulate the protein levels of CDKN1A, CDKN1B, CCND1, Bax, c-Caspase 3, c-Caspase 9, and PIK3R6, while down-regulate MYC, Bcl-2, and p-AKT in NB4 cells. CONCLUSION TPA induces NB4 cell cycle arrest in G₁ phase and promotes its apoptosis by regulating PIK3/AKT signaling pathway.

OBJECTIVE: To explore the effect of dichloromethane extraction phase of ethanol extract from stem of Patrinia scabiosaefolia Fisch.(DPSS) on proliferation and differentiation of K562 cells and its related mechanism. METHODS: MTT assay was used to detect the effects of DPSS at 0, 25, 50, 100 and 200 μg/ml on the proliferation of K562 cells at 24, 48 and 72 hours. Flow cytometry was used to analyze the changes of cell cycle and apoptosis at 24 and 48 hours. Wright-Giemsa staining was used to observe the morphological changes of K562 cells. The cell surface antigens CD33 and CD11b were detected by flow cytometry. RESULTS: The proliferation of K562 cells treated with different concentrations of DPSS was inhibited in a time-dose dependent manner (r=-0.96). Cell cycle analysis showed that with the increase of DPSS concentration, cells in G₂/M phase increased (r=0.88), and cells were blocked in G₂/M phase. Flow cytometry results showed that with the apoptosis rate of K562 cells was the highest when treated with 200 μg/ml DPSS for 48 h. Morphological observation showed that the K562 cell body increased, the amount of cytoplasm increased, the ratio of nucleus to cytoplasm decreased, and the nuclear chromatin was rough after DPSS treatment. Cell differentiation antigen, CD33 and CD11b, were positively expressed after treated with DPSS. CONCLUSION DPSS can induce apoptosis through cell cycle arrest, inhibit the proliferation of K562 cells, and induce K562 cells to differentiate into monocytes, which has a potential anti-leukemia effect.
