AIM:To investigate the effect of suramin concentration changes on trabeculectomy in rabbit, and to provide treatment strategies for glaucoma on the basis of experiment.
METHODS:Thirty-two albino rabbits were randomly divided into four groups, including standard control group, experimental group Ⅰ, experimental group II, and experimental group Ⅲ. Each eye was performed standard trabeculectomy. During surgery, standard control group was given a piece of cotton with 0. 3mg/mL mitomycin C ( MMC ) for 2min, and the other three groups were given a piece of cotton with 0. 3, 0. 4, and 0.5mg/mL suramin respectively for 2min. The filtering blebs and intraocular pressure ( IOP ) were observed at the 3, 7, 15, and 30d after surgery. Some conjunctiral specimen were observed with hitochemicall ( HE staining) and immunohistochemicall methods.
RESULTS:At postoperative 7, 15, and 30d, the changes of the IOP, functional filtering blebs, and the number of positive cell nuclear in experimental group II and experimental group Ⅲ were significantly different compared with those in standard control group and experimental group Ⅰ (all P<0. 05), and the differences between experimental group Ⅰ and standard control group were not significant (P>0. 05). The changes of the IOP and the number of positive cell nuclear in experimental group Ⅲ were significantly different compared with those in experimental group II (P<0. 05), whereas the differences in functional filtering blebs between experimental group Ⅲ and experimental groupII were not significant (P>0. 05). The status of filtering channel in experimental groupII and experimental group
Ⅲ were better than those in experimental group Ⅰ and standard control group.
CONCLUSION: The concentration of suramin has a significantly influence on its effect. When the concentration is 0. 3mg/mL, the antiproliferative effect of suramin is no more than that of MMC. The effect of 0. 4, 0.5mg/mL suramin is better than MMC. 0. 5mg/mL suramin has a better effect on controlling IOP and suppressing the growth of fibroblasts than 0. 4mg/mL suramin.

Objective To analyze the discourse right construction of China’s medical aid to Africa,so as to provide evidenc?es for improving the effect and sustainable development of China’s medical aid to Africa. Methods The documents of the dis?course right that China constructed in the medical aid to Africa were selected at different periods as discourse samples. The achievement and deficiency were analyzed from four aspects,namely confident,charismatic,influential,and dominant. Re?sults China’s medical team made much in the discourse right construction in their aid to Africa,but some China’s medical team members were still too cautious and too low?key. China’s medical team gained the trust of the people of Africa,but the lan?guage communication difficulties still hampered in China’s medical aid to Africa. Chinese medical team were widely praised by the African society,but in the west,some African media,even China’s media still neglected to report China’s doctors. China’s international discourse right were greatly improved,but western countries still dominated the public opinion. Conclusion Chi?na should refer to the actual situation of medical aid to Africa to strengthen the construction of discourse right.

BACKGROUND: MyoD gene is one of family members of muscle transcription factors. Transfection MyoD gene can switch on the procedure of differentiation of muscles, and transit non-muscle cells into muscle cells.The MyoD gene only expresses in skeletal muscles. Based on the same contractive structure in myocardial cells and skeletal muscle cells, it is imagined that the conversion from exogenous MyoD gene-induced fibroblast in local myocardium into skeletal muscle cells that had contractive function may become another method in the treatment of congestive heart failure on clinic.OBJECTIVE: To construct and identify a recombinant adenoviral vector carrying MyoD gene for further studies on the recovery function of MyoD gene in myocardial injury.DESIGN: Single sample experiment.SETTING: Department of Cardiology, First Affiliated Hospital, Nanjing Medical University.MATERIALS: The experiment was conducted at the Laboratory of Microbiology and Immunology, Nanjing Medical University between September 2004 and September 2005. MyoD gene and non-replicating form expressive vector of adenovirus were taken as research materials.METHODS: MyoD cDNA fragments were extracted from plasmids pEMSV-MyoD with polymerase chain reaction (PCR), and PCR was used to clone the whole-length gene of MyoD. After adding CACC sequence at 5' end, MyoD gene was cloned by orient topology into transfer ventor, pENTR/D-TOPO. Objective gene was transferred into adenoviral expression vector DNA via pENTR/D-TOPO vector. The recombinant adenoviral vectors transfected into HEK293A cells by using lipofectamine were packaged and amplified.MAIN OUTCOME MEASURES: Evaluation of PCR and DNA sequencing were used for confirming the size of segment and correctness of rank of MyoD cDNA and detecting the titre of virus.RESULTS: MyoD recombinant adenovirus contained target segment with precise length confirmed by PCR and DNA sequence that was correct. The titre of virus was 1.3×1011 pfu/mL.CONCLUSION: The recombinant adenoviral vector carrying MyoD gene is constructed successfully.

Objective To investigate the different expression levels of Na+ - K+ - 2Cl- co- transporter NKCC1 mRNA in the cochlea of rats after sodium salicylate injection and to explore the mechanism underlying the change of outer hair cells, induced by different salicylate administration. Methods Twenty-four normal adult rats were randomly divided into four groups with six rats in each group. Rats in control group,did not recieve sodium sa-licylate injection. The other three groups were acute group,chronic group,and recovered group according to the dif-ferent doses of sodium salicylate. The fluorescence quantitative PCR method was used to detect the expression levels of NKCC1 mRNA in the rat cochleas of the four groups. Results NKCC1 mRNA was expressed in all of the four groups. After sodium salicylate injection, the expressions of NKCC1 mRNA in chronic and recovered group were higher than that in control group(P<0.05). While the expression of NKCC1 mRNA in acute group was lower than that in control group(P(0. 05). Conclusion The expression of NKCC1 mRNA in the normal cochlea indicates that NKCC1 may play an important role in the maintenance of Cl- in the endolymph of the cochlea. The alteration of NKCC1 mRNA expression caused by sodium salicylate injection may lead to the change of the outer hair cell electro-motility.
