妊娠期脂代谢异常与子痫前期发生的相关性研究

目的分析妊娠期脂代谢异常与子痫前期发生的关系。方法回顾性选取2019年1月至2020年1月于新疆医科大学第一附属医院产检并分娩的53例子痫前期产妇作为观察组,并选取同期医院产检并分娩的53例正常产妇作为对照组。记录两组产妇妊娠早、中、晚期的脂代谢指标,分析其与子痫前期发生的关系。结果两组早、中、晚期的甘油三酯(TG)、总胆固醇(TC)、高密度脂蛋白胆固醇(HDL-C)、低密度脂蛋白胆固醇(LDL-C)水平比较,差异具有统计学意义(P<0.001);进一步两两比较发现,两组晚期TG、HDL-C、LDL-C分别与两组早期及中期比较,差异具有统计学意义(P<0.001),两组中期TC与观察组早期及对照组晚期比较,差异具有统计学意义(P<0.001),但观察组中期与晚期TC及对照组早期与中期TC比较,差异无统计学意义(P>0.05)。经Logistic回归分析结果显示,不同妊娠期脂代谢水平与子痫前期的发生有关,妊娠早、中、晚期TG、TC、LDL-C升高及HDL-C降低可能是子痫前期发生的风险因子(P<0.05);绘制受试者工作特征(ROC)曲线结果显示,妊娠早、中...     

Th17 cell‐derived miR‐155‐5p modulates interleukin‐17 and suppressor of cytokines signaling 1 expression during the progression of systemic sclerosis

Background miR‐155‐5p is associated with autoimmune diseases. T helper 17 (Th17) cells, interleukin (IL)‐17, and suppressor of cytokines signaling 1 (SOCS1) have important roles in the pathogenesis of systemic sclerosis (SSc). The purpose of this study was to explore the role of miR‐155‐5p in the regulation of IL‐17 and SOCS1 expression in Th17 cells and the subsequent effect on SSc disease progression.MethodsTh17 cells were isolated from peripheral blood mononuclear cells of SSc patients and healthy controls (HCs). RT‐qPCR and western blotting were used to examine the expression patterns of miR‐155‐5p, IL‐17, and SOCS1. Luciferase reporter assays were performed to confirm SOCS1 as a target of miR‐155‐5p. RNA pull‐down assays were performed to detect the interaction of IL‐17 and SOCS1 with miR‐155‐5p. In situ hybridization was performed to analyze the co‐expression pattern of miR‐155‐5p and IL17A in Th17 cells.ResultsThe levels of Th17 cell‐derived miR‐155‐5p were significantly up‐regulated in SSc patients compared with HCs, and its levels were negatively correlated with SOCS1 levels. Meanwhile, miR‐155‐5p positively regulated IL‐17 expression levels in Th17 cells isolated from SSc patients as the disease progressed. Using pmirGLO vectors, SOCS1 was confirmed as a target of miR‐155‐5p. The binding status of IL‐17 and SOCS1 to miR‐155‐5p was related to SSc progression. An increase in the co‐localization of miR‐155‐5p and IL‐17 was associated with greater SSc progression.ConclusionsIL‐17 and SOCS1 expression modulated by Th17 cell‐derived miR‐155‐5p are critical for SSc progression, which may provide novel insights into the pathogenesis of SSc.

Early postoperative pain after subxiphoid uniportal thoracoscopic major lung resection: a prospective,single- blinded,randomized controlled trial

Open in a separate window OBJECTIVESPreoperative selection bias led to the inability to generalize the proposed benefit of subxiphoid uniportal video-assisted thoracoscopic surgery (SVATS) as having less postoperative pain than uniportal intercostal VATS. So, we conducted this prospective, single-blinded, randomized controlled trial to investigate the hypothesis that SVATS may have less early postoperative pain than UVATS in patients who undergo major lung resection for early-stage lung cancer.METHODSA total of262 patients were randomly allocated between 2 groups (each with 131 patients), the first being the UVATS group and the second being the SVATS group. The values indicated on the numerical rating scale (NRS) of pain were collected at 24 h and 48 h during rest and during coughing. In addition, different perioperative variables were analysed and compared between the 2 groups.RESULTSMultiple linear regression analysis showed that the type of surgical approach was a significant predictor of the postoperative NRS values. The postoperative NRS pain values were significantly lower in the SVATS group after 24 h during rest and coughing and after 48 h during coughing. Postoperatively, patients in the SVATS group got out of bed significantly earlier [16.37 (2.54) vs 18.05 (3.29) h, p < 0.001]. The SVATS group showed a significantly higher rate of intraoperative arrhythmia [20 (15.3%) vs 3 (2.3%) patients, p = 0.03].CONCLUSIONSSVATS major pulmonary resection in early-stage lung cancer is associated with less early postoperative pain than the UVATS approach. Operating on patients with cardiac problems using the SVATS approach is still a limiting factor for randomization due to the potential compression on the heart with resulting arrhythmia.Clinical trial registrationThe trial was registered under clinical trials.gov Identifier: {"type":"clinical-trial","attrs":{"text":"NCT03331588","term_id":"NCT03331588"}}NCT03331588. https://clinicaltrials.gov/ct2/show/{"type":"clinical-trial","attrs":{"text":"NCT03331588","term_id":"NCT03331588"}}NCT03331588.     

Targeted peptide-modified oxidized mesoporous carbon nanospheres for chemo-thermo combined therapy of ovarian cancer in vitro

Ovarian cancer remains one of serious hazards to human health due to many drawbacks of existing available treatment options. In this study, a multifunctional chemo-thermo combined therapy nanoplatform (OMCNPID) was successfully prepared, which is composed of I₆P₈ peptide as a targeting moiety to interleukin-6 receptors (IL-6Rs), oxidized mesoporous carbon nanospheres (OMCN) as a near infrared (NIR)-triggered drug carrier and doxorubicin (DOX) as a chemotherapeutic drug and fluorescent agent. The synthesized multifunctional nanoplatform displayed high storage capacity for drugs and excellent photothermal properties. Besides, DOX was rapidly released from OMCNPID at the condition of low pH and NIR laser irradiation due to the dissociation of DOX from graphitic cores of OMCN. In vitro experimental results verified that OMCNPID could be markedly taken up by SKOV-3 monolayer cells and tumor spheroids, and revealed a remarkable synergistic chemo-photothermal effect against ovarian cancer. All the results demonstrated that OMCNPID is a pH/NIR dual-stimulus responsive nanoplatform and can achieve efficient chemo-thermo combined therapy.
