BACKGROUND： Emergency physicians frequently encounter patients with acute small bowel obstructions （SBO）. Although computed tomography （CT） imaging is the current gold standard in the assessment of patients with suspected SBO in the emergency department, a few studies have examined the use of ultrasound as an alternative imaging technique. METHODS： We evaluated the accuracy of ultrasound performed in the ED by a variety of providers （physicians with various levels of training, physician assistants） compared to CT imaging in 47 patients with suspected SBOs. RESULTS： Our data demonstrated a sensitivity of 93.8% and a specificity of 93.3% when compared to abdominal CT, and a sensitivity of 94.3% and specificity of 95.2% using a composite endpoint of abdominal CT and discharge diagnosis. CONCLUSION： Ultrasound can play an important role in the identification of small bowe obstructions in ED patients.

Matrix metalloproteinase-26 (MMP-26, endo-metase and matrilysin-2), a novel member of the MMPs family, is detected not only in the placenta and uterus, but is widely expressed in malignant tumors from different sources as well as in diverse tumor cell lines. However, the function of MMP-26 in the reproductive system has never been reported. Expression of MMP-26 in mouse embryos and the function of the MMP-26 antibody during mouse embryo implantation was examined for the first time by injecting the uterine horn, immunohistochemistry, in situ hybridization, co-culture of mouse blastocysts and uterine monolayer epithelial cells, Western blot, RT-PCR, Northern blot and zymography. Our results show that there is strong expression of MMP-26 niRNA and protein in the mouse embryo. Furthermore, the MMP-26 antibody dramatically inhibited mouse embryo implantation and significantly inhibited adhesion and outgrowth of mouse blastocysts on in vitro uterine monolayer epithelial cells. At the same time, the MMP-26

Drug delivery to the posterior segment of the eye, especially the retina, faces the unique challenges of various anatomical and physiological barriers. Invasive intravitreal injection is currently the mainstream clinical approach to posterior eye diseases such as age-related macular degeneration, diabetic retinopathy, uveitis, and cytomegalovirus retinitis. Repeated injections could be complicated by endophthalmitis, intra- ocular pressure elevation, retinal vascular occlusion, and ret- inal detachment, let alone the psychological and economical burdens suffered by patients （Schwartz et al., 2014）. In view of this, several extended release drug delivery systems have been devised and the idea of encapsulated-cell technology （ECT） has gained popularity in recent decades since its first proposal in the 1960s.
