ABSTRACT
Objective To explore the correlation between HLA-A, B alleles polymorphism and hemorrhagic fever with renal syndrome (HFRS) among Han nationality in Zunyi area. Methods Using group study, HLA-A, B genotypes were conducted in 100 HFRS cases and 100 controls among Han nationality in Zunyi area with polymerase chain reaction-sequence specific primer (PCR-SSP), gene frequency (GF) and relative risk (RR) were compared and calculated. Results The frequencies of HLA-A * 31 and HLA-B * 58 alleles in HFRS cases (GF=4%,12.5%) were strikingly higher than that in the healthy controls (X2=6.380, 7.792, P<0.05;RR=18.47,2.91). The frequencies of HLA-B * 40 alleles in HFRS cases (GF=11%) were strikingly higher than that in the healthy controls (X2=6.095,P<0.01, RR=O.47). Conclusion HLA-A * 31, B * 58 genes are positively related to HFRS of Han nationality in Zunyi area, HLA-B * 40 gene is negatively related to HFRS of Han nationality in Zunyi area.
ABSTRACT
OBJECTIVE:To study the application of antimicrobials in patients undergoing elective cesarean section and to promote rational use of drugs in our hospital. METHODS: 240 cases of elective cesarean section were randomly selected from our hospital during Jan.～Apr. in 2009 and Jul.～Oct. in 2009, respectively (n=120). Retrospective analysis was applied to analyze the application of antimicrobials in those cases. RESULTS: Prophylactic application of antimicrobials was rational after intervention with cephalosporins as the main category. The phenomena of excessive dose of drugs were controlled effectively to shorten medication duration. The rate of medication 0.5～2 h before operation increased and the cost of medicines reduced. CONCLUSION: Relevant measures of intervention can improve rational use of drugs in perioperative patients undergoing elective cesarean section in our hospital and reduce the cost of operation.
ABSTRACT
Objective:To explore the association between HLA-DR,DQ allele polymorphisms and onset of epidemic hemorrhagic fever(EHF)among Han Nationality in Zunyi area.Methods:Using group study,HLA-DR and DQ genotyping was conducted in 100 EHF cases and 100 controls among Han Nationality in Zunyi area with polymerase chain reaction-sequence specific primer(PCR-SSP),GF(gene frequency)and RR(relative risk)were calculated and compared.Results:The frequency of HLA-DRB1 16 in patients with EHF was higher than in the control group(RR=3.58,?2=4.916,P=0.0266
ABSTRACT
Objective:To investigate frequencies and polymorphism of HLA-DRB1 and DQB1 allele in the Hans of Zunyi area.Methods:Polymerase chain reaction-sequence specific primers(PCR-SSP) were used to type HLA-DRB1 and DQB1 genes of 200 unrelated healthy Han individuals in Zunyi area.Results:13 HLA-DRB1 and 7 HLA-DQB1 alleles were obtained at low resolution level in all subjects.The allele DRB1*09,DRB1*08 and DQB1*05 were showed high distributing frequencies;The allele DRB1*10 and DQB1*04 were scarcely found with low distributing frequencies.Comparied with Northern and Southern Han people,it would seem that Han people in Zunyi are more closely related to the Southern ones.The allele B*07 was scarcely found in the Southern Han with a high distributing frequency(GF=2.0%).Conclusion:HLA-DRB1 and DQB1 of Han people in Zunyi have plenty of polymorphisms.They seem to distribute in line with the Southern Han's characteristics but have their own territory feature with a high B*07 frequency.
