A new species of natricine snake of the Southeast Asian genus Opisthotropis GUnther, 1872 is described from western Hunan Province of China based on both mitochondrial DNA and morphological data. The new species is morphologically most similar and genetically most closely related to O. cheni Zhao, 1999 and O. latouchfi （Boulenger, 1899）, but possesses considerable genetic divergence （p- distance 5.1%-16.7%） and can be differentiated from all other congeners by a combination of the following morphological characters：（1） body size large （total length 514-586 mm） and strongly built; （2） dorsal scale rows 17 throughout, feebly keeled anteriorly and moderately keeled posteriorly; （3） ventral scales 147-152, subcaudal scales 54-62; （4） preocular absent, Ioreal elongated and touching orbit; （5） supralabials 8-9, fifth and sixth entering obit; （6） anterior temporals short, length 1.74-2.04 times longer than width; （7） maxillary teeth subequal, 28-30; （8） dorsal surface of head with distinct irregular yellow stripes and markings edged with ochre; （9） body with clear black and yellow longitudinal streaks, partly fused to several lighter patches or thicker stripes anteriorly; and （10） venter pale yellow, with asymmetric blackish speckles along outer margin. We present an updated diagnostic key to all members of the genus Opisthotropis, and recommendations on the ecological study for the group are provided.

Insect Science 2010年第6期17卷 535-541页

作者： Xing-Hui Liang Zhong-Ren Lei jin-Zeng Wen Ming-Liang zhu State Key Laboratory for Biology of Plant Diseases and Insect Pests Institute of Plant Protection Chinese Academy of Agricultural Sciences Beijing China

The daily flight activity of westem flower thrips, Frankliniella occidentalis （Pergande）（Thysanoptera： Thripidae） was examined using color, yellow-light and chemical attractant traps in a cucumber greenhouse and under controlled laboratory conditions. In the greenhouse, flying thrips were most abundant between hours 08：00-10：00, declined at mid-day, and then slightly increased during hours 14：00-16：00; however they decreased to a very low level at 18：00. The use of light traps showed no thrip flight activity during the night. The total number of thrips that flew onto cards on rainy or cloudy days was higher than that on sunny days. We reconfirmed that traps treated with attractant attracted 4.0-9.4 times more thrip than the untreated traps. Under laboratory controlled conditions, thrip flight activity was highest under light intensity between 4 000 and 6 000 lux, air temperature of 28℃, and RH of 70%. In addition, starved thrips flew more readily than non-starved thrips.

World Journal of Gastroenterology 2016年第48期22卷 10673-10679页

作者： guo-Xin Wang Xiang Liu Sheng Wang Nan Ge jin-Tao guo Si-Yu Sun Endoscopy Center Shengjing Hospital of China Medical University

AIM To analyze the effects of premedication with Pronase for endoscopic ultrasound(EUS) examination of the *** This was a prospective, randomized and controlled clinical study. All patients were randomly assigned to either the Pronase group or placebo group. The pretreatment solution was a mixed solution of 20000 U of Pronase and 60 m L sodium bicarbonate solution in the Pronase group, while an equal amount of sodium bicarbonate solution was administered to the placebo group. All operators, image evaluators and experimental recorders in EUS did not participate in the preparation and allocation of pretreatment solution. Two blinded investigators assessed the obscurity scores for the EUS images according to the size of artifacts(including ultrasound images of the gastric cavity and the gastric wall). Differences in imaging quality, the duration of examination and the usage of physiological saline during the examination process between the Pronase group and the control group were *** No differences existed in patient demographics between the two groups. For the gastric cavity, the Pronase group had significantly lower mean obscurity scores than the placebo group(1.0476 ± 0.77 vs 1.6129 ± 0.96, respectively, P = 0.000). The mean obscurity scores for the gastric mucosal surface were significantly lower in the Pronase group than the placebo group(1.2063 ± 0.90 vs 1.7581 ± 0.84, respectively, P = 0.001). The average EUS procedure duration for the Pronase group was 11.60 ± 3.32 min, which was significantly shorter than that of the placebo group(13.13 ± 3.81 min, P = 0.007). Less saline was used in the Pronase group than the placebo group, and the difference was significant(417.94 ± 121.38 m L vs 467.42 ± 104.52 mL, respectively, P = 0.016).CONCLUSION The group that had Pronase premedication prior to the EUS examination had clearer images than the placebo group. With Pronase premedication, the examination time was shorter, and the amount of saline us

Covariance of Floral and Vegetative Traits in Four Species of Ranunculaceae:A Comparison between Specialized and Generalized Pollination Systems

Journal of Integrative Plant Biology 2008年第9期50卷 1161-1170页

Theory predicts that tighter correlation between floral traits and weaker relationship between floral and vegetative traits more likely occur in specialized flowers than generalized flowers, favoring by precise fit with pollinators. However, traits and trait correlations frequently vary under different environments. Through detecting spatiotemporal variation in phenotypic traits （floral organ size and vegetative size） and trait correlations in four Ranunculaceae species, we examined four predictions. Overall, our results supported these predictions to a certain degree. The mean coefficient of variation （CV） of floral traits in two specialized species （Delphinium kamaonense and Aconitum gymnandrum） was marginally significantly lower than that of another two generalized species （Trollius ranunculoides and Anemone obtusiloba）. The two specialized species also showed marginally significantly smaller CV in floral traits than vegetative size across the two species. The absolute mean correlation between floral and vegetative traits, or that between floral traits in species with specialized flowers was not significantly lower, or higher than that in generalized plants, weakly supporting the predictions. Furthermore, we documented a large variation in trait correlations of four species among different seasons and populations. Study of covariance of floral and vegetative traits will benefit from the contrast of results obtained from generalized and specialized pollination systems.

Nanotechnology-based strategies for treatment of ocular disease

Ocular diseases include various anterior and posterior segment diseases. Due to the unique anatomy and physiology of the eye, efficient ocular drug delivery is a great challenge to researchers and pharmacologists. Although there are conventional noninvasive and invasive treatments, such as eye drops,injections and implants, the current treatments either suffer from low bioavailability or severe adverse ocular effects. Alternatively, the emerging nanoscience and nanotechnology are playing an important role in the development of novel strategies for ocular disease therapy. Various active molecules have been designed to associate with nanocarriers to overcome ocular barriers and intimately interact with specific ocular tissues. In this review, we highlight the recent attempts of nanotechnology-based systems for imaging and treating ocular diseases, such as corneal d iseases, glaucoma, retina diseases, and choroid diseases. Although additional work remains, the progress described herein may pave the way to new,highly effective and important ocular nanomedicines.

为获得紫薇硬枝扦插的最佳繁殖方法,以美国红叶紫薇、“红云”紫薇、“农紫1号”紫薇3个品种为试验材料,分别以不同品种、不同激素种类、不同激素浓度为试验因素,对紫薇的硬枝扦插繁殖进行了对比试验。结果表明:春季3月下旬至4月上旬进行硬枝扦插,插前将插穗基部在NAA、IBA以及(NAA+IBA)1500 mg/L的溶液中浸泡2 h后进行扦插,30 d后调查发现,3个品种以“农紫1号”紫薇的生根效果最好,生根率最高达92.4%。单独使用NAA、IBA溶液或使用NAA与IBA的混合溶液对扦插效果的影响不显著,对于扦插效果的影响主要体现在浸泡溶液的浓度上,使用1500 mg/L效果最好,与其他水平间均存在显著差异,该浓度下紫薇的平均生根率为91.00%,平均根长为3.00 cm,平均根量为7.93条。
