作者： Piu Chan Hua Bai Rong Chen J willian Langston Department of Neurology Xuanwu Hospital of the Capital University of Medical Sciences Beijing 100053 China The Parkinson's Institute 1170 Morse Avenue Sunnyvale California 94089 USA Department of Neurology Xuanwu Hospital of the Capital University of Medical Sciences Beijing 100053 China The Parkinson's Institute 1170 Morse Avenue Sunnyvale California 94089 USA The Parkinson's Institute 1170 Morse Avenue Sunnyvale California 94089 USA

Objective': To screen for exonic and point mutations in the Parkin gene in both Chinese and American Caucasian younger onset Parkinson's disease (YOPD) ***: Recently, the Autosomal recessive juvenile parkinsonism (ARJP) gene was first mapped to chromosome 6q25.2-27 and was late cloned and designated as Parkin. A wide variety of mutations, including homozygous exonic deletions and point mutations,have been found in at least more than 50 ARJP families of Japanese, European and Jewish origins. However, the distribution of Parkin gene mutations is not known in the Chinese and American Caucasians, It is also not clear how frequent the Parkin gene mutations occur in YOPD patients. Method and Material: Twenty-one Chinese subjects were selected from 121 Chinese PD inpatients who were admitted to the Xuanwu Hospital in Beijing between August of 1998 and April of 1999 and had an onset before age 51. Thirty-eight American subjects were PD patients with an onset before age 41 from the Tissue Bank of the Parkinson′s Institute at California. Homozygous exonic deletion and point mutations in all 12 exons of the Parkin gene were screened using PCR, SSCP and direct sequencing methods. Mutations identified by sequencing were further confirmed by restriction enzyme digestion. Results: Five different types of homozygous deletion mutations (exons 1, 4, 6, 7 and 12) were found in 7 out of 21 Chinese cases but none of the 37 American Caucasian patients in all 12 exons of Parkin gene. One novel and four polymorphic mutationswere found in the American Caucasian YOPD ***: our results suggest that homozygous exonic deletions in the Parkin gene may account for a significant amount of YOPD in the Chinese but not in the American Caucasian YOPD.

The silkworm Bombyx mori feeds exclusively on mulberry leaves and is highly sensitive to pesticides in general. Although mulberry plantations are free of agrochemicals, pesticide drift can occur. Chlorantraniliprole, a novel insecticide of the anthranilic diamides class, has been used to control pests in field crops. In this study, we investigated the biological effects of different concentrations of chlorantraniliprole on B. mori silkworm commercial Brazilian hybrids. To evaluate the toxicity of chlorantraniliprole, bioassays were carried out and data on the lethal concentrations, symptomatology, morphology and variables of silk production were collected. Results indicated that B. mori is extremely sensitive to chlorantraniliprole, even in low concentrations. The highest silkworm mortality rates were observed in the two highest chlorantraniliprole concentrations, 0.2 and 0.1 ppm. Although lower chlorantraniliprole concentrations did not cause death of all the silkworm larvae, various symptoms of toxicity were observed: feeding cessation, regurgitation, late development and incomplete ecdysis. Such symptoms reflect the morphological changes we observed in the midgut epithelium, which affected nutrient uptake and metabolism, and even the production of cocoons. Exposed larvae also produced?thin-shelled cocoons, which constitutes a serious economic problem because this type of cocoon is not useful for the silk industry. The results provided herein confirm the toxicity of chlorantraniliprole in silkworm larvae. Therefore, we strongly suggest that, competent authorities of the National Health Surveillance Agency, in pesticide management should take measures to reduce or eliminate the use of chlorantraniliprole in areas nearest to silkworm cultivation.

砷剂是常见的刺激物,会引起接触组织如皮肤,胃肠道以及呼吸道的炎性反应。砷剂还具有接触性变应原的作用,以致较低的剂量都会使以前敏感的人出现反应。注意在足够量时,砷会通过在皮肤、肝、中枢神经系统、周围神经、动脉内皮、心肌以及骨髓中的积蓄而产生有害作用。曾有报道慢性过量的砷吸收会使皮肤癌,肺癌,乳腺癌以及淋巴腺瘤的危险度增加。

我所追求的生活

时代英语（高三版） 2017年第5期 6-6页

作者：威廉·萨默塞特·毛姆

That must be the story of innumerable couples, and the pattern of life it offers has a homely grace. It reminds you of a placid rivulet, meandering smoothly through green pastures and shaded by pleasant trees,till at last it falls into the vast sea; but the sea is so calm, so silent, so indifferent,that you are troubled suddenly by a vague uneasiness.
