Objective: : EID3 (EP300-interacting inhibitor of differentiation) was identified as a novel member of EID family and plays a pivotal role in colorectal cancer development. However, its role in glioma remained elusive. In current study, we identified EID3 as a novel oncogenic molecule in human glioma and is critical for glioma cell survival, proliferation and invasion. Methods: : A total of five patients with glioma were recruited in present study and fresh glioma samples were removed from patients. Four weeks old male non-obese diabetic severe combined immune deficiency (NOD/SCID) mice were used as transplant recipient models. The subcutaneous tumor size was calculated and recorded every week with vernier caliper. EID3 and AMP-activated protein kinase α1 (AMPKα1) expression levels were confirmed by real-time polymerase chain reaction and Western blot assays. Colony formation assays were performed to evaluate cell proliferation. Methyl thiazolyl tetrazolium (MTT) assays were performed for cell viability assessment. Trypan blue staining approach was applied for cell death assessment. Cell Apoptosis DNA ELISA Detection Kit was used for apoptosis assessment. Results: : EID3 was preferentially expressed in glioma tissues/cells, while undetectable in astrocytes, neuronal cells, or normal brain tissues. EID3 knocking down significantly hindered glioma cell proliferation and invasion, as well as induced reduction of cell viability, apoptosis and cell death. EID3 knocking down also greatly inhibited tumor growth in SCID mice. Knocking down of AMPKα1 could effectively rescue glioma cells from apoptosis and cell death caused by EID3 absence, indicating that AMPKα1 acted as a key downstream regulator of EID3 and mediated suppression effects caused by EID3 knocking down inhibition. These findings were confirmed in glioma cells generated patient-derived xenograft models. AMPKα1 protein levels were affected by MG132 treatment in glioma, which suggested EID3 might down regulate AMPKα1 through protein degradation. Conclusion : Collectively, our study demonstrated that EID3 promoted glioma cell proliferation and survival by inhibiting AMPKα1 expression. Targeting EID3 might represent a promising strategy for treating glioma.

The clinical application of doxorubicin (DOX) in cancer chemotherapy is limited by its life-threatening cardiotoxic effects. Chrysophanol (CHR), an anthraquinone compound isolated from the rhizome of L., is considered to play a broad role in a variety of biological processes. However, the effects of CHR׳s cardioprotection in DOX-induced cardiomyopathy is poorly understood. In this study, we found that the cardiac apoptosis, mitochondrial injury and cellular PARylation levels were significantly increased in H9C2 cells treated by Dox, while these effects were suppressed by CHR. Similar results were observed when PARP1 activity was suppressed by its inhibitors 3-aminobenzamide (3AB) and ABT888. Ectopic expression of PARP1 effectively blocked this CHR׳s cardioprotection against DOX-induced cardiomyocyte injury in H9C2 cells. Furthermore, pre-administration with both CHR and 3AB relieved DOX-induced cardiac apoptosis, mitochondrial impairment and heart dysfunction in Sprague-Dawley rat model. These results revealed that CHR protects against DOX-induced cardiotoxicity by suppressing cellular PARylation and provided critical evidence that PARylation may be a novel target for DOX-induced cardiomyopathy.

Objective To investigate the expression change and their clinical role of triggering receptor expressed on myeloid cells-1 (TREM-1) in patients with severe thoracic trauma.Methods A prospective cohort study was conducted to analyze the clinical data of 52 patients with severe thoracic trauma (trauma group) hospitalized from October 2016 to May 2017.The peripheral anticoagulant blood samples were collected at days 1,3,5,7 and 14 after trauma.Meanwhile,10 healthy volunteers were enrolled in control group and their blood samples were collected once.According to injury severity score (ISS),the patients were divided into ISS low-score group (＜ 20 points,n =15) and high-score group (≥20 points,n =37).The patients were assigned to traumatic non-sepsis group (n =34) and traumatic sepsis group (n =18) by the latest definition and standard of sepsis 3.0 issued by the Society of Critical Care Medicine (SCCM)/European Society of Intensive Care Medicine (ESICM).The expressions of TREM-1 on neutrophils and monocytes were measured by flow cytometry.Pairwise comparisons were done between trauma group and healthy volunteers,ISS low-score group and ISS high-score group,and traumatic sepsis group and non-sepsis group,respectively.The accuracy of traumatic sepsis prediagnosis by TREM-1 was evaluated by the area under receiver operating characteristic curve (AUC).Results Trauma group had 41 males and 11 females,with age of (45.9 ± 12.4) years,Abbreviated Injury Scale (AIS) of (3.5 ± 0.6) points and Injury Severity Score (ISS) of (23.6 ± 8.5) points.Control group had eight males and two females,with the age of(29.1 ± 2.8) years.Compared to control group,trauma group had slightly lower TREM-1 expressions in neutrophils and significantly higher expressions in monocytes at days 1 to 14 (all P ＜ 0.01).ISS high-score group had slightly lower TREM-1 expressions in neutrophils than ISS low-score group at days 1 to 7,with significant difference at day 1 (P ＜ 0.05).ISS high-score group had slightly higher TREM-1 expressions in monocytes than ISS lowscore group at days 1 to 14,with significant difference at day 14 (P ＜ 0.05).Compared to traumatic non-sepsis group,traumatic sepsis group had significantly lower TREM-1 expressions in neutrophils at days 1 to 14 (all P ＜ 0.05).Traumatic sepsis group had slightly lower expressions in monocytes than traumatic non-sepsis group at days 1 to 7,with significant difference at day 3 (P ＜ 0.05).AUC and 95％ CI evaluating the role of neutrophils TREM-1 in traumatic sepsis prediagnosis were 0.852 (0.738,0.966) at day 1,0.835 (0.721,0.948) at day 3,0.797 (0.654,0.939) at day 5,0.756 (0.599,0.914) at day 7,and 0.707 (0.525,0.888) at day 14,respectively.Conclusions After severe thoracic trauma,the expressions of TREM-1 are decreased in neutrophils but increased in monocytes.TREM-1 might be used to assess the injury severity and has certain value in prediagnosis for traumatic sepsis.

Objective: To investigate the therapeutic effect of free superficial circumflex iliac artery perforator (SCIP)flap for reconstruction of soft tissue defects secondary to resection of retromolar and lateral buccal squamous cell carcinoma. Methods: From January 2014 to January 2017, eight patients with retromolar and lateral buccal squamous cell carcinoma received radical resection and reconstructed with SCIP flap immediately. CTA and color Doppler sonography were routinely performed before the surgery. According to the size of the defect in the recipient area, the flap vascularized by the perforator vessel was carefully prepared and transferred to the buccal-pharynx-palate composite defect. The recipient area and donor area were sutured tightly after arteriovenous anastomosis under microscope. The survival and functional recovery of the flap were observed after operation. Results: The flap sizes ranged from 5 cm× 6 cm to 7 cm×9 cm.The mean diameter of the superficial circumflex iliac arteries was 0.65 mm. And the mean diameter of the veins was 1.2 mm. The mean arterial pedicle length was 7.0 cm, and the venous pedicle length was 8.0 cm. Eight flaps were all survived. The shape of the buccal-parapharyngeal-palate was good and the mouth opening was normal after operation. Conclusions Superficial circumflex iliac artery perforator flap was a good choice for repairing the defect of parapharyngeal squamous cell carcinoma in the posterior molar region.
