Journal of Zhejiang Chinese Medical University 2014;(2):175-177
[Objective] To discuss the clinical effect of Levofloxacin in eye drop and oral taking on preventing infection for eyes traumas during perioperative period. [Method] Respectively select 126 cases of non-open eye trauma operation and 162 cases of open eye trauma operation, divide the non-open eye trauma patients into group A(Levofloxacin eye drop) 66 cases and group B(Levofloxacin injection in vein drop) 60 cases, compare both bacteria culture positive rates before administration and after operation;divide the open eye trauma patients into group C(Levofloxacin in eye drop and oral taking)80 cases and group D(Levofloxacin in vein drop) 82 cases, compare both positive rates of bacteria culture before and after the administration and operation.[Result] Comparing group A and group B with groups C and D, the positive rate before and after Levofloxacin administration, there ’s difference of statistical meaning, but without marked statistical meaning after operation. Side effects: the positive rate of bacteria culture was 56.25% before administration, and 10.13% after operation; for group D, they were 59.80% and 12.20% respectively, the difference had statistical meaning on Levofloxacin, but without difference of statistical meaning on positive rate. Purely using focal eye drop had no side effects on group A; the side effects of oral taking and focal administration on group C were much lower than groups B and D. [Conclusion] For eye trauma in perioperative period, the oral taking and eye drop of Levofloxacin have the same effects on infection prevention compared as vein drop, while the focal administration can reduce antibiotics usage and systemic administration, with little side effects, as wel as effectively prevent post-operation infection of eye trauma, worth clinical promotion and application.

6.Effects of Intracerebral Transplantation of Genetically Modified Myoblasts Producing BDNF on Different Brain Regions of Neonatal Rats Subjected to Hypoxic-ischemic Encephalopathy
Chinese Journal of Perinatal Medicine 1998;0(02):-
Objective To investigate the neuroprotection of different brain regions after transplantation of genetically modified myoblasts producing brain derived neurotrophic factor (BDNF) into cortices of neonatal rats subjected to hypoxic ischemic encephalopathy (HIE). Methods Seven day old pups were randomized into sham operated group (C), HIE+BDNF group (B) and HIE+mock transplantation group (A). A rat myoblast cell line expressing and secreting BDNF (BDNF(+)/L 6TG) was constructed. A stereotaxical intracerebroparenchymal transplantation of either BDNF(+)/L 6TG (B) or BDNF(-)/L 6TG (absence of BDNF, A) at 0.8 ?l of cell suspension (4?10 4/?l) into the left cortex of the brain was carried out shortly after HIE undergone by ligation of left common carotid artery followed by a 2.5 h inhalation of humidified 8% O 2+92% N 2 at 37℃. Changes of areas of different brain regions of cortex, hippocampus and striatum at different sections were observed 21 d after the procedure. Injury severity scores of brain tissues were also performed. Results Twenty one days after the manipulation, various degrees of atrophy were observed in the three regions of left hemispheres in group A or B versus contralateral corresponding regions or group C whereas this atrophy in group B was significantly reduced when compared to group A. Not only was the atrophy of cortex near the grafting point alleviated but some other regions of left hemispheres. A similar change pattern was seen in injury severity scores of the tissue. Conclusion Present data suggest that intracerebral transplantation of genetically modified myoblasts producing BDNF has a beneficial effect on the protection from damage of both circumscriptus brain tissues and some other areas distanced from the grafted place.
7.The DNA Sequence Difference of ERG11 Gene Between the Yeast-form and the Hyphal-form of Candida albicans
Chinese Journal of Dermatology 2003;0(08):-
Objective To explore the difference of gene sequence between the yeast- and the hyphal-form of Candida albicans. Methods The genomic DNA of both the yeast-form and the hyphal-form of seven isolates were extracted. The isolates were obtained from the same patient infected with HIV, but their sensitivities to fluconazole were different. These isolates were derived from the same C.albican strain as identified by chromosomal analysis and DNA subtype analysis. DNA fragments (310 bp) of ERG11 were amplified by PCR and the difference of DNA sequence between the two forms of each isolates was compared by DNA sequencing. Results Three isolates were found to have sequence difference between the yeast- and the hyphal-form of C. albicans at the position of 1 547 bp, 1 587 bp and 1 617 bp. Conclusion The sequence difference of ERG11 gene exists between the yeast- and the hyphal-form of C. albicans.
8.Expression and function of protease-activated receptor-2 on tumor cells
Cancer Research and Clinic 2008;20(9):646-648
Protease-activated receptor-2 (PAR-2) belongs to the receptor family which is coupled with G-protein. The N-terminus of PAR-2 is cleaved by some proteases to generate a new N-terminus. The new N-terminus can interact with and activate the receptor itself. The update research reported that PAR-2 could be expressed on some cancers as well as tumor cell lines. There are some relationships between the PAR-2 expression and the behaviors of tumor cell, such as proliferation, angiogenesis, migration and invasion.
