Arnebia euchroma is the main source for medicinal herb Zicao. and its most important component shikonin compounds have high medicinal and industrial value. This research is aimed to build overexpression vectors and RNAi vectors for key secondary metabolism genes of A. euchroma, and bulid platform for constructions of related transgenic lines using GATEWAY technology. To build genetic material based genetic research platform is to provide a great convenience for digging and functional verification of the genes on secondary metabolic pathway, and also to fill the gaps in transgenic research of A. euchroma. This study is also important for the cultivation of shikonin high-yielding strains of A. euchroma.

Organophosphate chemicals are widely used as agricultural pesticides and war reagents, their biodegradation is emphasized on the theoretical and practical aspects. Organophosphate hydrolases play important roles in the biodegradation of organophosphate chemicals. Great advancement was achieved recently in the determination of crystal structure and catalytic mechanisms of the hydrolase. This paper reviewed the research progresses in the enzymology, protein structure, catalytic mechanisms and application of the organophosphate hydrolase, and predicted the future research in this field.

AIM: To observe the surgical effects of the taumatic lens subluxation and cataract after manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation.
METHODS: A 3. 0mm tunnel limbus incision was operated through the predicted bulbar conjunctiva and sclera on 26 cases ( 26 eyes ) with taumatic lens subluxation ( suspensory ligament rupture range less than 120 ) and cataract (Ⅰ ~ Ⅲ) . And after the manual fragmentation and emulsification of nucleus, foldable intraocular lens was implantated. Intraocular lens loop was imbedded in the middle of the lens zonular ligament breakup to reset the pouch. The surgical complications and postoperative vision changes were observed.
RESULTS:Three month after operation, 22 eyes had a intraocular lens centric position taking up 85% of the whole. Four eyes had a slightly eccentric position ( 1 ~2mm), taking up 15% of the whole. 21 eyes had their visual acuity 0. 5~0. 8, taking up 81% of the whole. Five eyes of visual acuity was 0. 2~0. 8. Within 24h intraocular pressure of 12 eyes (46%) after operation were elevated, and returned to normal after 2~7d. There was no severe complication during operation and postoperation.
CONCLUSION: The manual fragmentation and emulsification of nucleus and foldable intraocular lens implantation of the traumatic lens subluxation and the cataract through the 3. 0mm corneal sclera limbus tunnel incision is a simple and effective surgery.

AlM:To investigate the prevalence of pterygium of the household population aged 40 and above in Hengli Town of Dongguan.
METHODS: Using the method of cluster random sampling, select 3 628 people aged 40 and above in four villages and one community for visual examination, intraocular pressure check, slit lamp examination and questionnaire.
RESULTS: The actual number of subjects was 3 393 people, and examination rate was 93. 52%. We detected 843 patients with pterygium. The prevalence of pterygium was 24. 85%.
CONCLUSlON:There is high prevalence of pterygium in Dongguan area. The prevalence of pterygium is related with age and working environment, but has no relation with gender.

A fragment sized 400bp of White spot syndrome virus(WS SV,formerly de signated NOSV),recovered from recombinant plasmid pAFD, was labeled with Digox igenin as a probe to detect dynamic distribution of WSSV within 120h and 72h in crawfishes(Cambarus proclarkii) inoculated WSSV by oral taking and injecti on r espectively. Stomach epithelium, intestine epithelium, heart, gill, haemolymph, muscle, hepatopancreas, hypoderm, connective tissue and ovary of infected crawfi shes were examined for WSSV. In both groups, WSSV was first detected in heamoly mph at 12h p.i. and then disappeared. Again it was detected at 96h p.i. only in oral infection group and maintained till 120h p.i., but it didn't appear at 72h p.i. in injection group. WSSV in heart, muscle was detected at 36h p.i. in oral infection group and 24h p.i. in injection group respectively, and then increased generally. In addition, WSSV in intestine epithelium, connective tissue, ovary of oral infection group and intestine epithelium, hypoderm, ovary of injection g roup could also be detected. In dead crawfishes after 120h and 72h p.i. in two groups, WSSV could be detected in all the examined tissues and it demonstrated t hat systemic infection occurred in the animales. The tissue containing more amo unts of WSSV was hypoderm in oral infection group, while intestine epithelium, g ill, hypoderm, ovary in injection infection group. It deduced that WSSV first a ppears in haemolymph and then goes into heart, muscle and other tissues and prol iferates in them. Once again, WSSV is released into heamolymph resulting in syst emic infection till crawfishes' death.

Hemolysins of Leptospira interragans have been shown to be the virulence factor in the pathogenesis of leptospirosis and 10 potential hemolysin genes were charecterized by genomic annotation of L.interrogans serovar.Lai strain 56601. In the present study, the LA0202 gene supposed to encode one of the new potential hemolysin was cloned and the protein encoded was purified. The purified protein was shown to have highly hemolytic activity as demonstrated on the sheep blood agar plate. It was also confirmed that the LA0202 protein-mediated hemolysis on sheep erythrocytes was osmotically protected by PEG6000. Meanwhile, this protein could induce pore formation on sheep erythrocytes and cause damages on the membrane of human L-02 liver cells. In addition, it could induce apoptosis of human L-02 liver cells after treatment of cells with this protein for 24 hours. It is evident that LA0202 protein acting as a pore-formong hemolysin can induce cytotoxic damage on mammalian cells.
