Objective To explore psychological resilience, anxiety, depression, coping styles and social supports status among parents of preterm infants of ophthalmic clinic, and analyze their relationship. Methods A total of 217 parents of preterm infants at ophthalmic clinic of hospital were selected by convenience sampling method and investigated by self- designed general information questionnaire, Connor-Davidson Resilience Scale, Self-rating Anxiety Scale, Self-rating Depression Scale, Social Support Rating Scale, and Simplified Coping Style Questionnaire. Results The total score of psychological resilience was (67.48 ± 14.20) points. The average score of positive coping styles dimension was (1.98±0.50) points, and negative coping style dimension score was (1.19±0.55) points. The social support score was moderate with a total score of (42.75 ± 6.17) points, the anxiety and depression got a total score of (36.77 ± 8.17) points and (39.67 ± 9.02) points respectively. Psychological resilience was negatively correlated with anxiety and depression (r=-0.363--0.242, P<0.01), and was positively correlated with coping styles and the social support (r=0.141-0.312, P<0.05 or 0.01). Multi-factor linear regression analysis showed that depression and social support were the influence factors of psychological resilience(t=-4.376, 2.516, P<0.01 or 0.05). Conclusions The parents of preterm infants are at the poor psychological states. Coping styles and depression are the important factors which affect psychological resilience among parents of preterm infants. Nurses should assess the psychological status of the parents, provide targeted interventions to relieve stress, guide the parents use social support effectively, and improve their psychological state.

OBJECTIVE:To establish a method for simultaneous determination of 5 effective components in Luohua zizhu dry extract. METHODS:UPLC-MS/MS was conducted. The separation was performed on an Zorbax Eclipse Plus C18 column with mo-bile phase of acetonitrile-water(gradient elution)at the flow rate of 0.3 mL/min.

Objective To explore the distribution of parvovirus B19 (HPVB19) infection in patients with leukopenia.Methods Patients who visited the Affiliated Hospital of Hangzhou Normal University from January 2015 to June 2016 were analyzed.Patients with peripheral leucocytes count less than 3.5×109/L were included in experiment group and healthy people were included in control group.HPVB19 IgG and IgM were detected by enzyme-linked immunosorbent assay, and HPVB19 DNA was detected by quantitative polymerase chain reaction.Differences in continuous data between two groups were compared with two-sample t test and those in categorical data were compared with Chi-square test.Results A total of 79 patients were included in experiment group, including 32 males and 47 females.Ages ranged from 24 to 62 years old.And 126 healthy individuals were included in control group, including 55 males and 71 females.Ages ranged from 28 to 67 years old.The positive rates of HPVB19 IgG, IgM and DNA in experiment group were 34.2%, 5.1% and 3.8%, respectively, while those in control group were 36.5%, 0 and 0, respectively.The detection rates of HPVB19 IgM and DNA between two groups were significantly different (χ2=6.507, P=0.011 and χ2=4.856, P=0.028, respectively).Sequence analysis for 3 of the HPVB19 DNA positive samples showed that there were two single nucleotide polymorphisms in VP1/VP2 sequence from one patient, which contributed to the 153rd (L/H) and 219th (N/Y) amino acids mutations, respectively.Phylogenetic analysis found that two strains belong to genotype 1a and one strain belongs to genotype 1b.Conclusions Detection rate of parvovirus HPVB19 infection (positive rates of HPVB19 IgM and DNA) in leukopenic patients is significantly higher than healthy controls.HPVB19 should be detected before considering transfusion in leukopenic patients in clinical practice.

OBJECTIVE:To systematically evaluate the efficacy and safety of simvastatin vs. pravastatin in the treatment of hy-perlipidemia,and provide evidence-based reference for the clinical treatment. METHODS:PubMed,Medline,EMBase,Cochrane Library and CJFD were retrieved to collect the randomized controlled trial(RCT)of efficacy and safety of simvastatin(test group) and pravastatin (control group) in the treatment of hyperlipidemia. The methodological quality of included studies was evaluated. The Rev Man 5.2 software was chosen for data analysis. RESULTS:14 RCT involving 1 019 patients were included. Meta-analysis showed that simvastatin had more significant effect in the decreasing of TC [MD=-0.34,95%CI(-0.52,-0.16),P<0.001] and LDL-C[MD=-0.31,95%CI(-0.45,-0.17),P<0.001] than pravastatin;and simvastatin and pravastatin had the similar effect in TG[MD=-0.06,95%CI(-0.18,0.05),P=0.28)] and HDL-C[MD=0.00,95%CI(-0.04,0.04),P=0.85]. Adverse drug reaction rate results showed they were similar[OR=0.70,95%CI(0.36,1.39),P=0.31]. CONCLUSIONS:Simvastatin is more effective in lipid-lowering than pravastatin with similar safety. Due to the limited number and low quality of included studies,it remains to be further verified with more reasonably designed,multi-center and large-sample studies.
