Inflammation plays a key role in the formation of intracranial aneurysm. At present, the pathophysiological processes of intracranial aneurysms are mainly caused by both hemodynamic abnormalities and inflammation. Studies have shown that the inflammatory cels in the intracranial aneurysm wal are mainly mononuclear macrophages, and can secrete various effector molecules, weakening and destroying the structures of the vessel wal . Therefore, the research of the roles of differences played in different subtypes of macrophages and their effector molecules in the pathophysiological processes of intracranial aneurysms wil provide clues for exploring the pathogenesis of intracranial aneurysms and effective targeted therapy.

0.05). In stratified studies, risk of asthma in individuals with null genotype of GSTM1 is 2.667 times of that with wild genotype after exposure to light air pollution. Risk of asthma in individuals living in heavy air pollution area is 2.125 time of that in light pollution area for all wild genotype of GSTM1 individuals, but without statistical significance. Conclusion It was not found that the relationship between GSTM1, GSTT1 polymorphism and asthma. Synergism of genotype of GSTM1, GSTT1 and air pollution was not also seen in this study.

Objective To study the changes and significance of Bid gene expression in hypoxic-ischemic brain damage (HIBD) in neonatal rats.Methods The animal models of HIBD were made. Total RNA from ipsilateral cerebral hemisph ere was extracted.RT-PCR was used to evaluate the levels of Bid gene expression at different time points after hypoxic-ischemic. Results The levels of Bid mRNA were higher in HIBD rats than those in normal rats.The ex pression of Bid mRNA in ipsilateral hemiphere following cerebral hypoxic-ischem ic began to increase at 6 h, increased to the highest level at 24 h, and then gr adually returned.Conclusion The upregulation of Bid mRNA can play a role in the induction of apoptosis fol lowing cerebral hypoxic-ischemic.

OBJECTIVE:To improve the quality of pharmacist consultation,provide real-time,precise and whole-process medi-cine guidance and to promote rational drug use. METHODS:The functions of electronic pharmacy consultation system(EPCS)in our hospital were introduced,and its effects were evaluated. RESULTS:The system had several modules as multiple dimensional knowledge assistant system,real-time prescription checking engine,electronic consultation record method,pharmacist workload and quality statistical analysis. EPCS provided convenient information access,prescription auditing,consultation record and statisti-cal analysis so as to improve consultation efficiency and accuracy. Compared with before using EPCS,EPCS had enhanced speed of inquiring information by 3.75 times,prescription auditing by 4 times,consultation record by 6 times and statistical analysis by 20 times;return visit rate to potients increased from 0.03% to 0.34%. The number of consulting questions increased month by month. The type of consultation question,the identity of the consultant and others could be classified statistically based on the sys-tem. CONCLUSIONS:EPCS helps pharmacist to build a more scientific and effective consultation platform,and promotes rational drug use in the hospital.

Objective To explore the protective effect of Red Sage Root on bronchopulmonary dysplasis(BPD) induced by hyperoxia in newborn rats.Methods On the 2nd postnatal day,SD newborn rats were randomly assigned to 4 groups:air and NS group(group Ⅰ),air and Red Sage Root group(group Ⅱ),hyperoxia and NS group(group Ⅲ),hyperoxia and Red Sage Root group(group Ⅳ).The rats in group Ⅲ and group Ⅳ were exposed to hyperoxia(the level of oxygen was 900-960 mL/L).The rats in group Ⅱ and group Ⅳ were injected with Red Sage Root intraperitoneally(10 mg/kg)daily.On 14 days after birth,6 rats in each group were killed.Lung histologic changes,radical alveolar counts(RAC)were monitored.Thiobarbituric acid method,nitrite method,2-nitroben zoic acid method were used to determine the concentration of malony ldialdengde(MDA),superoxidedismutase(SOD),glutathione peroxidase(GSH-Px) were monitored.Results 1.Group Ⅲ and group Ⅳ showed the inhibition of lung development and the evident lung fibrosis.In contrast to group Ⅰ and group Ⅱ,RAC in group Ⅲ and group Ⅳ decreased dramatically(Pa

Objective To study the early diagnostic indices of melioidosis by analyzing 49 cases. Methods Unconditional logistic regression analysis was used to analyze the clinical data of 49 cases of melioidosis and 98 cases of bacterial pneumonia who were admitted in our hospital and Peoples' Hospital of Hainan Province from December 1996 to December 2007. Their social characteristic,background diseases,clinical manifestations,laboratory findings,radiologic examination and complications were studied. Results Background disease (such as diabetes),hepatosplenomegaly,septic shock,sepsis et al were the main causes of melioidosis. Conclusion Chills,fever,hepatosplenomegaly,diabetes mellitus,septic shock and sepsis are all factors that should be considered with melioidosis.

AIM: To screen TIGR/myocilin gene (MYOC) mutation in high myopic Chinese children with family history.METHODS: Gene sequencing was performed in exon 3 of the TIGR gene in high myopic Chinese Children. The coding sequence of TIGR exon 3 was screened by capillary electrophoresis sequencing. The sequence alterations were analyzed by bioinformatics.RESULTS: TIGR gene mutation was not found in high myopic patients and normal controls group.CONCLUSION: No identified gene mutation is found in TIGR gene in high myopic Chinese children.

Background Statistic data revealed that different retinopathy of pre-term infants have different susceptibility to retinopathy of prematurity (ROP),which may be associated with polymorphism of vascular endothelial growth factor(VEGF) gene.Objective This study was to determine the association of polymorphisms of VEGF gene with the risk for ROP.Methods This research was approved by Ethics Committee of Hunan Children's Hospital,and written informed consent was obtained from the parents of patients.A prospective case-controlled study was designed.Ninety-nine ROP patients in Hunan Children' s Hospital and 88 pre-termed children without ROP were included from January,2006 to December,2009.Thirty-nine patients who received retinal photocoagulation or cryotherapy were included as the treatment group,and 60 untreated but spontaneously regressed ROP patients as the non-treatment group.No significant differences were seen in demography between with the ROP group and the without ROP group,or between the treatment group and the non-treatment group (all P＞0.05).2 mL of peripheral blood was collected for the extraction of DNA.Gene polymorphisms of VEGF-A+405 and VEGF-A936 were detected using the pyrosequencing method.Results No significant difference was found in the frequencies of the VEGF-A+405 gene polymorphisms between the ROP group and without ROP group (P =0.071,OR =0.675,95 ％ CI =0.444-1.026).Also no significant difference was found in the frequencies of the VEGF-A936 gene polymorphisms between with the ROP group and without the ROP group (P =0.118,OR =0.768,95 ％ CI=2.823-4.614).However,the frequencies of the VEGF-A+405 gene polymorphisms were significantly higher in the ROP treatment group than the non-treatment group (P＜0.01,OR--0.857,95 ％ CI =5.239-14.024),and VEGF-A936 gene polymorphisms was also significantly higher in the ROP treatment group than the non-treatment group (P =0.000,OR =3.609,95 ％ CI =0.711-0.829).Conclusions There is no association between the VEGF-A+405/VEGF-A936 single nucleotide polymorphism with the risk of ROP,but polymorphisms of VEGF gene may be correlated with the prognosis of ROP.The carrier of VEGF-A +405 /VEGF-A936 allele is more susceptible to ROP progression.
