Association of rs1 1 742688 polymorphism of DHFR gene with non-syndromie cleft lip with or without cleft palate in the northeast of China / 实用口腔医学杂志

Objective:To investigate the association between dihyrofolate reductase(DHFR)gene rs1 1 742688 polymorphism and non-syndrom cleft lip with or without cleft palate (NSCL/P)in northest Chinese population.Methods:PCR-restriction fragment length polymorphism(PCR-RFLP)was used to identify the rs1 1 742688 polymorphism of DHFR gene of 220 NSCL/P patients(inclu-ding 1 38 core families)and 1 80 healthy controls.Hardy-Weinberg test and SPSS statistical software were used to calculate the data, OR and 95% confidence intervalarents.Results:In case-contral analysis,there was no significant difference in TT genotype of rs1 1 742688 between NSCL/P subjects and the controls(χ2 =0.439,P >0.05)in.Conclusion:The polymorphism of rs1 1 742688 in DHFR gene is not associated with NSCL/P in northest Chinese population.

Observation on sterile effect of sterile adhesive tape on opened infusion bottle mouth / 中国实用护理杂志

Objective To discuss the sterile effect of sterile adhesive tape on opened infusion bottle mouth. Methods From February to May, 2009, 400 infusion bottles were chosen and divided into the observation group and the control group with 200 bottles in each. The bottle mouth in the observation group was covered with sterile adhesive tape, while the control group used iodophor. The incidence of infusion reaction, disposable materials and time consuming of nurses were compared. Results No infusion reaction occurred in both groups. But disposable materials and time consuming was less in the observation group compared with the control group. Conclusions Application of sterile adhesive tape in sterilization of opened infusion bottle mouth is safe, reliable, simple and economic, it can save time and increase work efficiency of nurses.
