OBJECTIVE To investigate the distribution features and clinical significance of allergens in patients with chronic rhinosinusitis(CRS). METHODS A retrospective analysis was performed in 136 cases of CRS. Allergen features were compared in the two subtypes of CRS: chronic rhinosinusitis with nasal polyps(CRSwNP) and chronic rhinosinusitis without nasal polyps(CRSsNP). Differences of allergens features of CRS were analyzed, and they were compared to the allergens of 36 patients with allergic rhinitis(AR). RESULTS The total allergen positive rate in CRS was 48.5％. The allergen positive rate, distribution proportion of inhaled and food allergens, distribution proportion of allergens subsets, distribution proportion of single and multiple allergens between two subtypes of CRS had no significant difference(P >0.05). The major allergens of CRS were single inhaled allergens(84.8％). Some CRS patients were allergic to food allergen(9.1％). The minority allergens of CRS were a mixture of inhaled and food allergens(6.1％). Compared to AR, the distribution proportion of inhaled and food allergens(χ2=14.801, P =0.001), the distribution proportion of allergens subsets(χ2=12.951, P=0.005), and the distribution proportion of single and multiple allergens(χ2=9.067, P=0.003) had significant difference. CONCLUSION The allergen positive rate of CRS is much higher than the prevalence of allergic diseases in general population, suggesting that allergic factors may be closely correlated to the pathogenesis of CRS. The clinical features of allergens are similar in the two subtypes of CRS, while there are significant differences in allergen distribution between CRS and AR patients. The detection of allergens may be helpful in prevention and treatment of CRS.

Baculoviral IAP(inhibitor of apoptosis protein) gene was identified firstly in IAP gene family.The structurcal feature of baculoviral IAP genes are characterized BIR and RING domain;Despite similar to P35 in antiapoptotic function,baculovrial IAP and P35 differ in structure and mechnism of action.Phylogenetic analysis of IAP genes and lots of evidence sppport the origin of this viral gene by capture of a host gene early in the evolution of Lepidoptera.

Generalized epilepsy with febrile seizures plus(GEFS+) is a new epilepsy syndrome proposed by International League Against Epilepsy.At present,the progress of genetic studies of GEFS+ focus on gene mapping based on family analysis,many researches indicate that GEFS+ is associated with voltaged-gated sodium channel(SCN) gene mutation.This paper intends to discuss the relationship beween GEFS+ and SCN1B,SCN2B,SCN1A,SCN2A genes,mutations in order to improve the cognition about GEFS+.

ObjectiveTo study neural protective effect of combined medication with nimodipine and mannitol on injury of cerebral ischemia-reperfusion for screening the better medication method in acute cerebral ischemia-reperfusion. MethodsA model of cerebral ischemia-reperfusion was performed by clipping bilateral common carotid artery of rats with vago- and releasing them 3 hours later. 40 Wistar female rats within 1 month were divided into 5 groups randomly with 8 rats each: model group (no use of medicine), nimodipine group(0.2mg/kg), mannitol group(0.5g/kg), nimodipine and mannitol group, sham-operated group (no use of medicine and no clipping process). The changes of SOD and MDA in brain tissue were measured 24 hours after cerebral ischmic reperfusion in all groups. At the same time pathologic study was performed to compare the different groups.ResultsThere were significant differences between nimodipine and mannitol group and other groups in changes of SOD, MDA and pathological changes(P<0.01). Conclusions Combined medication with nimodipine and mannitol is the better way to protect brain tissue from acute cerebral ischemia-reperfusion than other way in present experiment, by synergistic action.

Baculovirus DNA polymerase gene belongs to an early gene of baculovirus. It is a necessary gene required for replication of virus in insect cells. It can encode DNA polymerase induced by virus. In the process of replication, DNA polymerase can bind to homologous regions and non-homologous regions, which are believed to act as the origins of virus DNA replication with other replication factors. In addition, DNA polymerase has advantages over occlusion protein and egt gene for resolving deep branching taxonomic relationships of baculovirus phylogenies.

Objective To explore the mutation of voltage-gated sodium channel ?1 subunit(SCN1B)gene in Chinese Han families with generalized epilepsy with febrile seizures plus(GEFS+).Methods Two families pedigrees were established and disease history,physical examination were collected in order to analyze the mode of inheritance.The mutation sites of reported SCN1B gene exon 3-(C46T,G47A,C156G)were detected by polymerase chain reaction sequence special primers(PCR-SSP)method after genomic DNA were extracted.Results There were 13 patients in the 2 families,all were Han people and 9 cases were living.The results showed the mode of inheritance basically corresponds with autosomal dominant inheritance complicated with incomplete penetrance,and leaded to different kinds of phenotype.The mutation sites of SCN1B gene exon 3 were detected by using PCR-SSP method,and heterozygote was not found,and point mutations were also not found in the 2 families.Conclusions GEFS+ is a complex disorder with genetic heterogeneity.There were no gene mutations of SCNIB in the 2 GEFS+ families,which might suggets the possibility of insufficient samples as the patients came from Henan province and the possibility of differences from races and regions of other countries.
