With the progresses instudies, many insect-resistantgeneswere cloned and characterized. The classification of most insect-resistantgenes from plant, the functionalmechanism and the applications of theplantinsect-resistantgenes, the problems and prospectsforusing the plant insect-resistant genes in genetic engineering was described.
2.Overview on method and strategy of therapeutic material basis in traditional Chinese medicine by multidisciplinary approach.
China Journal of Chinese Materia Medica 2015;40(9):1644-1648
Traditional Chinese medicine (TCM) has a good reputation for preventing or healing diseases in clinic due to its higher efficacy, minor toxicity and abundant resources. Screening bioactive components in TCMs is not only crucial for clarifying their action mechanisms, but also the basis of their safety and quality control. TCM is characterized by multiple components, multiple targets and multiple mechanisms, however the complex composition of TCM makes it difficult to study the therapeutic material basis which has become the bottleneck in the process of its modernization and internationalization. Recently, with the rapid development of modern technologies and the unceasing progress of various disciplines, multidisciplinary approach, such as analytical chemistry, chemistry of TCM, pharmacology, cell biology, systems biology and bioinformatics has been successfully applied to the study of TCM. Multidisciplinary approach realizes the communication and interaction of multi-discipline, and accelerates the research and development of TCM. This review summarizes the application of multidisciplinary approach which may have certain potential of bringing new thoughts to TCM research and provide references for screening and identification of therapeutic material basis of TCMs.

AlM: To analyze, summarize and describe ophthalmic imaging features of posterior scleritis.
METHODS: Clinical data of 16 patients ( 21 eyes ) with posterior scleritis diagnosed in our hospital from October 2008 to June 2013 were retrospectively analyzed. The results of type-B ultrasonic, fundus chromophotograph, fundus fluorescein angiography, CT were recorded for comprehensive evaluation and analysis of ophthalmic imaging features of posterior scleritis.
RESULTS: All patients underwent type-B ultrasonic examination and manifested as diffuse and nodular types. The diffuse type showed diffusely thickened sclera and a dark hypoechoic area that connected with the optic nerve to form a typical “T”-shaped sign. The nodular type showed scleral echogenic nodules and relatively regular internal structure. FFA showed that relatively weak mottled fluorescences were visible in the arterial early phase and strong multiple needle-like fluorescences were visible in the arteriovenous phase, which were then progressively larger and fused; fluorescein was leaked to the subretinal tissue in the late phase;varying degrees of strong fluorescences with less clear or unclear boundaries were visible in the optic disk. CT results showed thickened eyeball wall.
CONCLUSlON: Posterior scleritis is common in young female patients, whose ophthalmic imaging features are varied and more specific in type-B ultrasonic. Selection of rational ophthalmic imaging examination method, combined with clinical manifestations, can accurately diagnose posterior scleritis and avoid the incidence of missed and delayed diagnosis.

Objective To evaluate the value of peripheral blood neutrophil CD_(64) level for early diagnosis of neonatal septicemia.Methods Thirty-six cases of neonatal septicemia were recruited into the study according to diagnostic criteria for neonatal septicemia:white blood cell count,C-reactive protein(CRP),platelet count,micro-erythrocyte sedimentatio rate(mESR) and blood culture;26 cases of hospitalized neonates with non-infectious diseases were enrolled as controls.The level of peripheral blood neutrophil CD_(64) was measured by flow cytometry.Results The level of peripheral blood neutrophil CD_(64) in septicemia patients were(60.37?22.70)mean fluorescence intensity(MFI),which were significantly higher than that of control group(23.14?5.10)MFI(P

In this study, three methods for identification of E.coli were compared. The conventional method was employed to select and identify the suspicious E.coli isolates from a fecal sample. PCR based ARDRA analysis was then carried out to distinguish these E.coli isolates, E.coli MG1655 and other bacterial species. All the potential E.coli isolates and E.coli MG1655 had the identical ARDRA banding pattern while the other bacterial species showed the different patterns.The result indicated that the ARDRA analysis was consistent with the traditional method for identification of E.coli and could be the practical method for distinguishing E.coli from other intestinal bacterial species. The ERIC-PCR analysis provided abundant polymorphism between different E.coli isolates, and might be a powerful approach for elucidating the genetic diversity among isolates of the same species.
