Zooplankton cyclops propagates profusely in waterbody, cannot be effectively inactivated by conventional disinfection process, and becomes a troublesome drinking water treatment problem. In this work, the qualitative and quantitative experimental studies were carried out on inactivation of zooplankton cyclops using oxidants, such as chlorine （Cl2）, chlorine dioxide （ClO2）, ozone （O3）, hydrogen peroxide （H2O2）, ozone/hydrogen peroxide （O3/H2O2）, chloramines （Cl2-NH3） and potassium permanganate （KM4nO4）. The influences of various factors include different oxidant dosages, organic substance contents and pH values. The results showed that currently available oxidants used all might inactivate cyclops in some extent. According to the experimental results, chlorine dioxide, ozone, ozone/hydrogen peroxide and chloramines can be selected as effective oxidants for inactivating cyclops because of their strong inactivation abilities. Then the synergic removal effects on cyclops with ozone, ozone/hydrogen peroxide pre-oxidation followed by conventional water treatment processes were investigated, The results showed that ozone and ozone/hydrogen peroxide pre-oxidation can inactivate cyclops effectively, which then can be removed thoroughly by conventional water treatment processes. Cyclops cannot appear in water after filtration with 1.65 mg/L of ozone and 6 mg/L of hydrogen peroxide, with the inactivation rate being 62% before conventional water treatment processes. Cyclops cannot appear in water after filtration with 1.8 mg/L of ozone, with the inactivation rate being 50% before conventional water treatment processes. For different oxidants, when removal rate was the best, the inactivation rate was not the same. These results may provide reference and model for actual waterworks.

AIM: To explore the association of methylation of the CpG island in the promotor of the p16 tumor suppressor gene with the clinicopathological characteristics of the colorectal cancers. METHODS: Methylation-specific PCR (MSP) was used to detect p16 methylation of 62 sporadic colorectal cancer specimens. RESULTS: p16 methylation was detected in 42% of the ***'staging was associated with p16 methylation status.p16 methylation occurred more frequently in Dukes'C and D patients (75.9%) than in Dukes'A and B patients (12.1%). CONCLUSION: p16 methylation plays a role in the carcinogenesis of a subset of colorectal cancer, and it might be linked to poor prognosis.

契理契机:佛教中国化的内在机理

“佛教中国化”是国际学界共同打造的关于文明互动、宗教传播、文化交流互鉴的一个研究范式,也是解读佛教与中国文化之间关系的一把钥匙。“契理契机”本来是中国佛教界在解释“修多罗”(契经)译名时,以众生根性为基础解释教化方式差异性的理由,后来成为理解佛教中国化的内在理路。作为不同文明相遇、宗教本土化的成功案例,“佛教中国化”首先是佛教界自身的任务,需实现“佛教认同”和“中国认同”,前者是“契佛教之理”,后者有两层涵义:一则通过契合“此时”“此地”“此人”“此境”的“契中国之机”,达成佛教在中国的四化——时代化、本土化、特色化、处境化;二则顺应中国的治理体系,实现佛教与中国治道的兼容。“佛教中国化”是求同存异,但不是简单的求与中华文化之“同”,也不是简单的凸显与中华文化之“异”,而是打通同异,在保留佛教特质(契理)的同时,形成与中华文化(契机)相容、互益的中国佛教形式,因而需要完成三个任务:其一,从历史上看,来自异域的佛教,与中华文明已有的核心元素和根本特征相容和生;其二,佛教融入中国文化,在中国文化体系中有自己独特的地位和功能,能进入并成为中华文明的整体构成;其三,佛教需与与时俱进的中国文化保持基本同步的发展节奏。“契理契机”是佛教中国化的内在机理,也是佛教实现时代转型的基本原则。

AIM: To study the effects of acetazolamide and anordiol on osmotic water permeability in aquaporin 1 (AQP1)-cRNA injected Xenopus oocyte and their mechanisms. METHODS: AQP1 gene constructed in pBluescript was transcripted into cRNA in vitro and then the cRNA was injected in Xenopus oocytes. The effects of acetazolamide and anordiol on the water transport function of AQP1 were observed by assaying the osmotic swelling of oocytes. In addition, their effects on protein expression of AQP1 were quantitatively investigated by Western blotting method. RESULTS: After incubation for 15 min or 72 h, acetazolamide, a carbonic anhydrase inhibitor, equally reduced the water permeability of AQP1-cRNA injected oocyte in a dose-dependent manner. After incubation for 72 h, anordiol, an antiestrogen with partial estrogenic activity, reduced the osmotic water permeability dose dependently as well; however, no discernable action was observed after incubation with anordiol for 15 min.
