Neuroinflammation is a key contributor to the pathogenic cascades induced by hypoxic-ischemic (HI) insult in the neonatal brain. AD-16 is a novel anti-inflammatory compound, recently found to exert potent inhibition of the lipopolysaccharide-induced production of pro-inflammatory and neurotoxic mediators. In this study, we evaluated the effect of AD-16 on primary astrocytes and neurons under oxygen-glucose deprivation (OGD) in vitro and in mice with neonatal HI brain injury in vivo. We demonstrated that AD-16 protected against OGD-induced astrocytic and neuronal cell injury. Single dose post-treatment with AD-16 (1 mg/kg) improved the neurobehavioral outcome and reduced the infarct volume with a therapeutic window of up to 6 h. Chronic administration reduced the mortality rate and preserved whole-brain morphology following neonatal HI. The in vitro and in vivo effects suggest that AD-16 offers promising therapeutic efficacy in attenuating the progression of HI brain injury and protecting against the associated mortality and morbidity.

Purpose:
The purpose of this study was to compare the survival and toxicities in cervical esophageal squamous cell carcinoma (CESCC) treated by concurrent chemoradiothrapy with either three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) techniques.
Materials and Methods:
A total of 112 consecutive CESCC patients were retrospectively reviewed. 3D-CRT and IMRT groups had been analyzed by propensity score matching method, with sex, age, Karnofsky performance status, induction chemotherapy, and tumor stage well matched. The Kaplan-Meier method and Cox proportional hazards model were used for overall survival (OS) and progression-free survival (PFS). Toxicities were compared between two groups by Fisher exact test.
Results:
With a median follow-up time of 34.9 months, the 3-year OS (p=0.927) and PFS (p=0.859) rate was 49.6% and 45.8% in 3D-CRT group, compared with 54.4% and 42.8% in IMRT group. The rates of grade ≥ 3 esophagitis, grade ≥ 2 pneumonitis, esophageal stricture, and hemorrhage were comparable between two groups, while the rate of tracheostomy dependence was much higher in IMRT group than 3D-CRT group (14.3% vs.1.8%, p=0.032). Radiotherapy technique (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.01 to 0.79) and pretreatment hoarseness (HR, 0.12; 95% CI 0.02 to 0.70) were independently prognostic of tracheostomy dependence.
Conclusion
No survival benefits had been observed while comparing IMRT versus 3D-CRT in CESCC patients. IMRT with fraction dose escalation and pretreatment hoarseness were considered to be associated with a higher risk for tracheostomy dependence. Radiation dose escalation beyond 60 Gy should be taken into account carefully when using IMRT with hypofractionated regimen.

BACKGROUNDThe safety of percutaneous coronary intervention (PCI) for chronic total occlusion (CTO) lesions in remote hospitals without surgical facilities remains unknown. This study aimed to evaluate three-year outcomes after CTO for PCI in ten centers around China where no on-site coronary artery bypass grafting (CABG) support was available.
METHODSA total of 152 patients from 10 Chinese hospitals without on-site surgical facilities were prospectively studied. Intra-procedural and in-hospital events were assessed. Angiographic follow-up was indexed eight months after the initial procedure. Clinical follow-up was extended to three years. The primary outcome was the rate of major adverse cardiac events (MACE), defined as cardiac death, myocardial infarction and target-vessel revascularization (TVR).
RESULTSThe incidence of CTO was 7.9% in patients who underwent PCI. Successful recanalization was achieved in 132 patients (86.8%). Compared with patients in the PCI success group, patients with PCI procedural failure had longer lesion lengths ((42.32 +/- 22.08) mm vs (27.61 +/- 22.85) mm, P = 0.023), a higher rate of perforation (25.0% vs 0, P = 0.014), and a greater need for pericardial puncture. There were significant differences in MACE in-hospital and at one year and three years between the failure (10.0%, 30.0% and 35.0%) and the success (3.0%, 12.1% and 14.4%) groups (P = 0.037, 0.034 and 0.040, respectively). These led to a significant decrease in the MACE-free survival rate at one and three years in the failure group, compared with the success group (P = 0.031 and 0.023, respectively). Stump was the only predictor of recanalization success (HR 0.158, 95% CI 0.041-0.612, P = 0.008), whereas procedural failure (OR 13.023, 95% CI 6.67-13.69, P = 0.002), incomplete revascularization (OR 9.71, 95% CI 2.93-5.59, P = 0.005), and total stent length (OR 6.02, 95% CI 1.55-11.93, P = 0.027) were three independent predictors of MACE.
CONCLUSIONSPCI for CTO was unsafe in remote hospitals without CABG facilities. Paying attention to coronary perforation is important for successful procedures.

BACKGROUNDBifurcation angles may have an impact on the clinical outcomes of crush stenting. We sought to compare high (> or = 60 degrees ) with low (< 60 degrees ) bifurcation angle in patients who underwent either classical or double kissing (DK) crush stenting for bifurcation lesions from the DKCRUSH-1 data base.
METHODSThere were 212 patients with 220 lesions, some with low-angle (n = 138) and some with high-angle (n = 74). Angiography was indexed at 8-month after procedure. Primary endpoint was the occurrence of major adverse cardiac events (MACEs), defined as cardiac death, myocardial infarction and target lesion revascularization (TLR). Secondary endpoint included late lumen loss, the rate of restenosis, and final kissing balloon inflation (FKBI).
RESULTSAt 8 months, clinical follow-up was 100%; angiographic follow-up was 75% in the low-angle group and 83.3% in the high-angle group. There were no significant differences in the FKBI between the high-angle group (91.43%) and the low-angle group (82.39%). In the high angle group, there was a significant difference in contrast volume used (P = 0.005) but no significant difference in acute gain, minimum lumen diameter (MLD), late loss and diameter stenosis in the pre-bifurcation segment, post-bifurcation segment or side branch. When lesions were assigned into with-(n = 133) and without-FKBI (n = 42), significant side-branch late loss was seen in the group without-FKBI ((0.65 +/- 0.49) mm vs (0.47 +/- 0.62) mm, P = 0.02), with a resultant greater restenosis rate (37.68% vs 18.32%, P = 0.001). No difference was detected in the MACE free survival rate between the high and low angle groups (82.39% vs 82.36%, P = 0.84). The rate of stent thrombosis tended to be higher in the lower-angle group although there was no significant difference (P = 0.38). The TLR free survival rate was 87.2% in the with-FKBI group vs 73.5% in the without-FKBI group (P = 0.001). Cox regression analysis showed that the independent predictors for target vessel revascularization were the side branch stent MLD post stenting (hazard ratios (HR) 1.028, 95% CI 2.357 - 16.233, P = 0.002), lack of FKBI (HR 4.910, 95% CI 4.706 - 8.459, P = 0.001) and unsatisfactory kissing (HR 3.120, 95% CI 2.975 - 5.431, P = 0.001).
CONCLUSIONSBifurcation angles do not influence the clinical outcome of crush stenting. Successful final kissing balloon inflation, regardless of bifurcation angles, can predict TLR.

BACKGROUNDBecause no data regarding the comparison of crush stenting with paclitaxel (PES) or sirolimus eluting stents (SES) for coronary bifurcate lesions have been reported, we compared the clinical outcomes of these two types of stents.
METHODSTwo hundred and thirty patients with 242 bifurcate lesions were enrolled in a prospective, nonrandomized trial. Primary endpoints included myocardial infarction, cardiac death and target vessel revascularization at 8 months.
RESULTSAll patients were followed up clinically and 82% angiographically at 8 months. Final kissing balloon inflation was performed in 72% in the PES and 75% in the SES groups (P>0.05). Compared to the SES group, PES group had a higher late loss and incidence of restenosis (P=0.04) in the prebifurcation vessel segment. The postbifurcation vessel segment in the PES group had a greater late loss ((0.7+/-0.6) mm vs (0.3+/-0.4) mm, P<0.001) and higher restenosis in the side branch (25.5% vs 15.6%, P=0.04) when compared to the SES group. There was significant difference of insegment restenosis in the entire main vessel between PES and SES groups (P=0.004). Target lesion revascularization was more frequently seen in the PES group as compared to the SES group (P=0.01). There was significant difference in the accumulative MACE between these two groups (P=0.01). The survival rate free from target lesion revascularization was significantly higher in the SES group when compared to the PES group (P<0.001).
CONCLUSIONSES is superior to PES in reducing restenosis and target lesion revascularization by 8-month follow-up after crush stenting for bifurcate lesions.
