rhIL23R-CHR/Fc fusion protein inhibits Act-HaCaT inflammation and proliferation by downregulating ENST00000522718 / 中国药科大学学报

@#Psoriasis is an autoimmune disease characterized by chronic skin inflammation, and its etiology and pathogenesis have not been fully elucidated to date. In the previous study, rhIL23R-CHR/Fc fusion protein had been found to significantly relieve the symptoms of psoriasis mice and the pharmacological mechanism had been initially elucidated.In this study, we established a psoriasis cell model (Act-HaCaT) using TNF-α-activated human immortalized keratinocytes (HaCat).In our current study, the lncRNA that plays a key role in the regulation of Act-HaCaT function by the rhIL23R-CHR/Fc fusion protein was screened by transcriptome sequencing combined with qRT-PCR.The results showed that rhIL23R-CHR/Fc fusion protein significantly inhibited cell proliferation and inflammatory factor production in Act-HaCaT.lncRNA ENST00000522718 was obtained by screening, and knockdown of ENST00000522718 was found to significantly inhibit cell proliferation and inflammatory factor production.Our findings suggest that ENST00000522718 plays an important role in the pathological mechanism of psoriasis.

Research advances in effect of microglia on pathophysiology following traumatic brain injury / 中华创伤杂志

Microglia are the immune cells in central neural system. Microglia play an important role in central neural system such as surrounding environment monitoring, apoptosis induction and mature synapse formation. Besides, as a pathological process, traumatic brain injury (TBI) can cause the structure and function damage of central nervous system. While the activated microglia can change the TBI-induced pathological process and play an important role during the course of injury. Therefore, the authors review the important physiological function of microglia and its pathological role so as to provide references for clinical treatment.

Predictive value of ventricle late potential for arrhythmic events in the patients with Brugada syndrome / 中华老年医学杂志

Objective To explore the predictive value of ventricle late potential (LP) for arrhythmic events in the patients with Brugada syndrome. Methods Totally 43 patients with Brugada syndrome were divided into symptom group (n=24) and asymptom group (n=19).Signalaveraged electrocardiography(SAECG) was performed to analyze characteristics of LP in all subjects.The occurrence of arrhythmic events was observed in all patients during the dynamic follow-up for (33.8±9.0) months.Results There were 22 cases (91.7％) and 7 cases (36.8％) with LP positive in patients with symptom and asymptom,respectively.The incidences of arrhythmic events were 72.4％ in Brugada syndrome patients with positive LP and 14.3％ in patients with negative LP,respectively.The relative risk (RR,95％ CI) for LP prediction of the arrhythmic events was [5.1,(1.4～ 18.6)] (P =0.002). ConclusionsLP may be one of effective factors predicting arrhythmic events in the patients with Brugada syndrome.
