Nonionic surfactant alkyl polyglucoside （APG） was prepared by direct glycosidation of alkyl alcohol with glucose in the presence of sulfate acid-silica gel （H2SO4/SiO2） as solid acidic catalyst. The quantity of catalyst was only of 1 wt%, based on the glucose, and the conversion of glucose was close to 100% at 110 ℃ in 1.5 h. The product was characterized by FT-IR, mass and ^1H NMR spectra. The degree of polymerization （DP） of the glucose in the product was 1.37, and critical micelle concentration （CMC） of product was only 0.0104 wt%.

Objective: Photoacoustic(PA) tomography(PAT) has attracted extensive interest because of its optical absorption contrast and ultrasonic detection. This study aims to develop a biocompatible and biodegradable PA contrast agent particularly promising for clinical applications in human ***: In this study, we presented a PA contrast agent: 1, 2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[methoxy(polyethylene glycol)](DSPE-PEG)-coated superparamagnetic iron oxide(SPIO) nanoparticles(NPs) loaded with indocyanine green(ICG). We used ICG and SPIO NPs because both drugs are approved by the U.S. Food and Drug Administration. Given the strong absorption of near-infrared laser pulses, SPIO@DSPE-PEG/ICG NPs with a uniform diameter of ~28 nm could significantly enhance PA ***: We demonstrated the contrast enhancement of these NPs in phantom and animal experiments, in which the in vivo circulation time of SPIO@DSPE-PEG/ICG NPs was considerably longer than that of free ICG. These novel NPs also displayed a high efficiency of tumor ***: SPIO@DSPE-PEG/ICG NPs are promising PAT contrast agents for clinical applications.

Testicular prostheses have been used to deal with anorchia for nearly 80 years. Here, we evaluated a novel testicular prosthesis that can controllably release hormones to maintain physiological levels of testosterone in vivo for a long time. Silastic testicular prostheses with controlled release of testosterone （STPT） with different dosages of testosterone undecanoate （TU） were prepared and implanted into castrated Sprague-Dawley rats. TU oil was applied by oral administration to a separate group of castrated rats. Castrated untreated and sham-operated groups were used as controls. Serum samples from every group were collected to measure the levels of testosterone （T）, follicle-stimulating hormone and luteinizing hormone （LH）. maximum intracavernous penile pressure （ICPmax） was recorded. The prostates and seminal vesicles were weighed and subjected to histology, and a terminal dexynucleotidyl transferase-mediated UTP nick end labeling （TUNEL） assay was used to evaluate apoptosis. Our results revealed that the weights of these tissues and the levels of T and LH showed significant statistical differences in the oral administration and TU replacement groups compared with the castrated group （P 〈 0.05）. Compared with the sham-operated group, the ICPmax, histology and TUNEL staining for apoptosis, showed no significant differences in the hormone replacement groups implanted with medium and high doses of STPT. Our results suggested that this new STPT could release TU stably through its double semi-permeable membranes with excellent biocompatibility. The study provides a new approach for testosterone replacement therapy.
