The large-scale product has a big cylinder and the pressure-bearing capacity is also high. In the sealingtest, the water is filled in it to have the pressure test. But due to the over high pressure, the experiment tends todestroy the cylinder and the cover to cause the failure of the sealing and the waste of the cylinder and water. Sothis paper is to analyze how to add the small combined cylinder within the product cylinder. The water is filled be-tween the small cylinder and the product cylinder and the pressure on the cover is reduced during the sealing ex-periment.

Photocatalytic oxidation of emerging contaminants(ECs) in water has recently gained extensive attentions. In this study, bismuth oxychloride-based plasmon photocatalysts(BiBiOCl) exhibiting high performance were successfully developed by reducing Bion the surface of BiOCl. Consequently, the photocatalysts were used to remove ECs from *** effects of developmental process and Bi metal plasmon resonance on the photoelectric performances of Bi-BiOCl were investigated through a series of characterizations. The UV-vis diffuse reflection and photoluminescence spectra revealed that the light absorption range of the photocatalyst gradually increased and the electron recombination rate gradually decreased with the introduction of Bi metals. The optimal removal rates of ciprofloxacin and tetrabromobisphenol A by Bi-BiOCl were 93.8% and 96.4%;the respective reaction rate constants were 5.48 and 4.93 times higher than that of BiOCl. The mechanism study indicated that main reactants in the photocatalytic system were ·O-2radicals and photogenerated holes, and the existence of oxygen vacancies and Bi metals promoted electron transfer in photocatalyst. In conclusion, this research produces a novel, green, highly efficient, and stable visible light photocatalyst for the removal of ECs from water.

BACKGROUND： Radiation therapy is widely used to treat tumor of brain; however, irradiation of radiation into eye tissues may easily cause ischemia and hypoxia in retina and optic nerve tissue so as to induce radiation optic neurapathy. Noloxone is a specific antagonist of opiate receptor, and it can change injured effect of f3 -endorphin. OBJECTIVE： To observe the axoplasmic transport of optic nerve at various phases after radiation injury so as to investigate the mechanism and regularity of optic nerve injury; meanwhile, to verify the therapeutic effects of naloxone on radiation optic neurapathy. DESIGN： Randomized controlled animal study. SETTINGS： Medical College of Qingdao University, changzhi Medical College. MATERIALS： A total of 40 healthy adult New Zealand rabbits, weighing 2 - 2.5 kg, of either gender, were checked by using slit lamp and ophthalmoscop before radiation in order to exclude eye diseases. FCC-7000 vertical kilocurie ^60Co therapeutic machine was made in Yantai, China; in addition, naloxone was provided by Beijing Sihuan Pharmaceutical factory. METHODS： The experiment was carried out in the Animal Experimental Laboratory, Medical College of Qingdao University from January 2005 to December 2006. The experimental rabbits were randomly divided into radiation group （n =16）, treatment group （n =16）, blank control group （n=4） and injured control group （n=4）. Except blank control group, rabbits in other three groups were irradiated in as the center of optic chiasma including the area of optic nerve by using ^60Co therapeutic machine. Radioactive source was 85 cm away from head, and the size of operative field was 5 cm × 5 cm. The radiation was performed once a day with the dosage of 3 Gy for 8 days in total. The total dosage was 24 Gy. When radioactive dosage reached 24 Gy, 2 mg/kg naloxone was dropped into ear vein of rabbits in the treatment group once a day for 10 days in total. Rabbits in the injured control group were only irradiated but not given

OBJECTIVE:Toidentify the potential risk factors associated with Shenqifuzheng injection(SFI), a solution made of Dangshen(Radix Codonopsis) and Huangqi(Radix Astragali Mongolici), for the timely provision of information to regulatory ***: A comprehensive analysis of the production process, quality standards, pharmacology,post-marketing clinical studies, and safety evaluation using the primary literature of adverse reactions(ADR), case analyses, and systematic reviews,intensive hospital safety monitoring of post-marketing drugs, and data provided by the hospital in-formationsystem(HIS).RESULTS: Sub-acute toxicity tests suggesting that a dose of 15 mL/kg(concentrated solution) had specific biological effects, whereas a smaller dose engendered no observable effects. Long-term toxicity testing in domestic rabbits showed that after SFI was administered for 90 days, the animals in each dosing group showed no chronic toxic reactions. Among 20 100 cases observed, the incidence of an ADR was 1.85‰. From March to November 2013,of the leading institutions and 22 sub-centers involved in the post-marketing clinical safety intensive hospital monitoring, 21 units completed 8484 cases of monitoring, and reported 23 cases of adverse reactions. No damage to renal function was found using SFI ata dosageanda treatment course larger and longer than that recommended for the adjuvant treatment of tumors. This could reduce the mortality rate of admitted patients based on the analysis of the data provided by the HIS. A total of 16 clinical case reports of adverse reactions related to SFI in 1999-2012 were obtained through literature retrieval. These reports contained information concerning 17 cases, with adverse reaction symptoms including thrombocytopenia, rash,chills,feeling cold,palpitation,dyspnea,edemaofa lower extremity, palpebral edema, and superficial vein in flammation,among ***: This study introduces "get full access" to the flow of information on med
