ABSTRACT
Objective To investigate the effect of group psychological counseling and peer education on depressive and anxiety symptoms of pregnant females with selective multiple pregnancy reduction in second trimester. Methods Sixty-two pregnant females with selective multiple pregnancy reduction in second trimester were randomly divided into intervention group(n=30)and control group (n=32), two groups of pregnant women all received routine nursing. The pregnant women of intervention group received group psychological counseling and peer education for one month before multiple pregnancy reduction. Results Before the intervention, the anxiety levels of the two groups of pregnant women were not significantly different. After the intervention, the intervention group had less anxiety symptoms than before the intervention[ before(54.2 ± 3.2)points,after(43.4 ± 3.1)points,t=13.250,P=0.000].After the intervention, the intervention group had less anxiety symptoms than the control group[the intervention group(43.4±3.1)points, the control group(50.0±4.4)points,t=6.712,P=0.000].Before the intervention, the depression levels of the two groups of pregnant women were not significantly different. After the intervention, the depression levels of the control group was not significantly different than those before the intervention. After the intervention, there was significantly lower depression score of the intervention group than that of the control group(P < 0.05) [before(56.9 ± 3.5)points, after(45.3 ± 2.5)points, t=14.773,P=0.000].After the intervention, the intervention group had lower depression score than the control group[the intervention group (45.3 ± 2.5) points, the control group (54.6 ± 3.0) points, t=12.802,P=0.000]. Conclusions Group psychological counseling and peer education can effectively improve depressive and anxiety symptoms of pregnant females with selective multiple pregnancy reduction in second trimester.
ABSTRACT
Objective To understand the disinfectant resistance of clinically isolated Escherichia coli (E.coli)and carriage of disinfectant resistance genes.Methods Disinfectant resistance gene sugE (c ),sugE (p ),qacEΔ1 ,and qacE of 82 isolates of E.coli were detected with polymerase chain reaction (PCR),minimal inhibitory concentra-tions (MICs)were measured with agar dilution methods.Results Among 82 E.coli isolates,positive rates of dis-infectant resistance gene sugE (c ),sugE (p ),qacEΔ1 ,qacE,sugE (c )+qacEΔ1 ,and qacE+qacEΔ1 +sugE (c ) were 84.15% (n=69),1 .22% (n=1),76.83% (n=63),73.17 % (n=60),68.29% (n=56),and 59.76% (n=49)respectively.There was no significant differences in carriage status of four disinfectant resistance genes be-tween extended-spectrumβ-lactamases (ESBLs)-producing and non-ESBLs-producing strains,as well as cefepime sensitive and resistant strains (all P >0.05);MIC values of benzalkonium chloride,cetylpyridinium chloride,am-monium bromide,and triclosan for 82 isolates of E.coli were all > standard stain;MIC values of chlorhexidine for 32 isolates of E.coli were all > standard stain,for 50 other E.coli strains were all ≤ standard strain.There were no significant difference in MIC values of benzalkonium chloride,cetylpyridinium chloride,ammonium bromide,and triclosan between ESBLs-and non-ESBLs-producing strains,as well as cefepime sensitive and resistant strains(all P >0.05);while MIC values of chlorhexidine showed a significant difference (both P <0.05).Conclusion Detection rates of disinfectant resistance gene qacE,qacEΔ1 ,and sugE(c)in E.coli from clinical specimens are high,MICs of disinfectants such as benzalkonium chloride for E.coli are generally higher than standard strain.
