Ethmoid sinus foreign body can be divided into endogenous and exogenous, the clinically referred mostly belonging to the exogenous foreign body. The exogenous ethmoid sinus foreign body generally has a history of facial trauma, its clinical manifestations are associated with the foreign body size, nature, residence time and location. Using X-ray, CT scan can further confirm the diagnosis. Removing the ethmoid sinus foreign body may have a better therapeutic effect by endoscopic sinus surgery. Here we report a rare case of foreign body in the ethmoid sinus.

Objective To explore possible role of cellular repressor of E1A-stimulated genes(CREG) in the process of phenotypic switching of adventitial fibroblasts(AFs). Methods Immunofluorescent staining was performed with tissue sections from mouse carotid arteries to evaluate the relationship between the expression of CREG and smooth muscle actin-α(α-SMA) in injured arteries, especially in the adventitia. Tissue block pasted culture method was used to isolate and culture AFs. RT-PCR and Western-blot were used to detect the change of CREG andα-SMA mRNA and protein expression in AFs in the presence of different concentrations of AngⅡfor 12 h/24 h or in the presence of 100 nmol/L Ang Ⅱ for different times. Results Normal mouse carotid arteries had little α-SMA expression throughout the tunica adventitia. Arteries at day 1 and day 3 post-injury exhibited significantly higher immunofluorescence of α-SMA compared with non-injured arteries. Alpha-SMA expression began to decrease on day 7 and progressively declined on day 14. In contrast, immunofluorescent staining revealed that CREG was expressed in the adventitia of normal arteries. Expression of CREG in the adventitia of injured arteries was decreased on the 1st day, reached its lowest value on the 3rd day, and increased gradually from the 7th day, and was higher compared with that in non-injured arteries on the 14th day after injury. Similarly, the expression of CREG in AFs was very high, and AngⅡremarkably decreased mRNA and protein expression levels of CREG in a dose-dependent and time-dependent manner. Conclusions The changes in CREG expression correlate with AF phenotypic modulation, and CREG down-regulation may facilitate AF phenotypic switching into myofibroblasts (MFs).

Objective To retrospectively analyze the effectiveness and safety of drug-eluting stents (DES) on prevention of restenosis in old female patients (≥65 years) with multi-vessel coronary artery disease. Methods 387 old female patients with multi-vessel coronary artery disease underwent percutaneous coronary intervention (PCI) were divided into the DES group (n=139) and the metallic stent (BMS) group (n=248). Acute and long-term outcomes were compared between the two groups. Results The ratio of patients with diabetic disease was higher in DES group than that in BMS group (P0.05). The rates of restenosis shown by angiography and major adverse cardiac events (MACE) were significantly lower in the DES group compared with BMS group (4.2% vs 15.8%, 7.5% vs 17.3%, P

Objective To evaluate long-term clinical effectiveness in old female patients with multi-vessel coronary artery disease (≥65 years) treated with percutaneous coronary intervention (PCI). Methods 601 female patients with multi-vessel coronary artery disease underwent PCI were divided into the elder group (≥65 years, n=354) and the younger group (0.05). Conclusion PCI can be performed in old female patients with multi-vessel coronary artery disease with high success rate and few complications. Long-term clinical outcomes of PCI in old females with multi-vessel disease are similar to younger females.
