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.

The cell cycle inhibitor P21 promotes the development of pulmonary fibrosis by suppressing lung alveolar regeneration

The cell cycle inhibitor P21 has been implicated in cell senescence and plays an important role in the injury–repair process following lung injury. Pulmonary fibrosis (PF) is a fibrotic lung disorder characterized by cell senescence in lung alveolar epithelial cells. In this study, we report that P21 expression was increased in alveolar epithelial type 2 cells (AEC2s) in a time-dependent manner following multiple bleomycin-induced PF. Repeated injury of AEC2s resulted in telomere shortening and triggered P21-dependent cell senescence. AEC2s with elevated expression of P21 lost their self-renewal and differentiation abilities. In particular, elevated P21 not only induced cell cycle arrest in AEC2s but also bound to P300 and β-catenin and inhibited AEC2 differentiation by disturbing the P300–β-catenin interaction. Meanwhile, senescent AEC2s triggered myofibroblast activation by releasing profibrotic cytokines. Knockdown of P21 restored AEC2-mediated lung alveolar regeneration in mice with chronic PF. The results of our study reveal a mechanism of P21-mediated lung regeneration failure during PF development, which suggests a potential strategy for the treatment of fibrotic lung diseases.     

Effect of Rapamycin on TGF-β1- induced epithelial-mesenchymal transition in LoVo colonic adenocarcinoma cells

Objective:To investigate the effect of Rapamycin on epithelial-mesenchyrnal transition(EMT) of LoVo colonic adenocarcinoma cells in vitro.Methods:Cultured LoVo colonic adenocarcinoma cells were divided into three groups: negative control group,EMT-inducing group(TGF-β1) and EMT-interfering group(TGF-β1 plus Rapamycin).E-cadherin expression in LoVo cells was detected by Western Blot,while the expression of vimentin was evaluated through immunocytochemistry.The Snail mRNA in LoVo cells was examined by RT-PCR.Results:TGF-β1 induced LoVo cell switching from polygonal to spindle-shaped.TGF-β1 enhanced the expression of vimentin,but lowered the level of E-cadherin.In contrast,Rapamycin impaired the transition induced by TGF-β1.Rapamycin dramatically abrogated TGF-β1-induced vimentin expression and restored E-cadherin expression in LoVo cells.Rapamycin significantly repressed the up-regulation of Snail mRNA expression induced by TGF-β1.Conclusion:Rapamycin dramatically abrogated TGF-β1 induced Snail mRNA expression in LoVo cells,hence inhibiting EMT of these cells in vitro.
