Correlation between professional quality of life and social support of Chinese nurses: a meta-analysis / 中华劳动卫生职业病杂志

Objective: To systematically evaluate the correlation between professional quality of life and social support of Chinese nurses based on Pearson and Spearman correlation coefficients. Methods: In databases including PubMed, Cochrane Library, CINAHL, Medline, CBM, CNKI、Wanfang, and other databases were searched by computer for the literatures on correlation between Chinese nurses' professional quality of life and social support from January 2005 to July 2020. The Chinese and English search terms are "nurse" "professional quality of life" "empathy satisfaction" "empathy fatigue" "professional quality of life" "ProQOL" "comparison satisfaction" "comparison fatigue" "social support" "competent social support" "SSRS" "PSSS", etc. Literatures were screened according to the inclusion and exclusion criteria. After evaluating quality and extracting data, meta-analysis was conducted using RevMan 5.3 software. Results: A total of 12 studies were included. The meta analysis showed that nurses' compassion satisfaction, burnout, secondary traumatic stress were related to social support, summary r were 0.35, -0.26 and -0.23 respectively. The correlation between compassion satisfaction and social support were increased with sample, the south was higher than the north, and comprehensive departments were higher than other departments (P<0.05) . The correlation between burnout and social support were increased with time and sample, and the south was higher than the north, oncology was higher than others, non-random sampling was higher than random sampling, using ProQOL and Perceived Social Support Scale (PSSS) was higher than Professional Quality of Life Scale (ProQOL) and Social Support Racting Scale (SSRS) (P<0.05) . The correlation coefficient between secondary traumatic stress and social support in oncology was higher than others, random sampling was higher than non-random sampling, using ProQOL and PSSS was higher than ProQOL and SSRS (P<0.05) . Conclusion: There is a positive and weak correlation between compassion satisfaction and social support, and a negative and weak correlation between burnout and secondary traumatic stress and social support. There are differences in different time, research design, region and department.

The Fourier transform infrared spectra of the key organs derived from Kidney (Shen)-yang deficiency syndrome mice / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore an approach to rapidly and accurately identify the compounds as biomarkers of Chinese medicine (CM) syndromes.</p><p><b>METHOD</b>The Fourier transform infrared (FT-IR) spectrometry was applied to investigate the characteristic components of a mice model of Kidney (Shen)-yang deficiency syndrome (KDS), and the remedial effect of a typical CM formula Shenqi Pill (). Thirty-six females and 18 males of Balb/c mice were randomly divided into KDS, Shenqi or control group. The females and males of the same group freely were mated for 96 h, and the males were taken out and only the female mice were raised. Females of the KDS group were threatened by a ferocious cat every other day for 14 d. After delivery, the KDS, or gestational threatened, offspring were raised at standard condition for 11 weeks. Then 10 male offspring were randomly selected, anaesthetized and their representative organs, i.e. testes, kidneys, lungs and feet were collected, for the FT-IR scan. Mice of the Shenqi group were intragastric administered Shenqi Pill; while mice in the KDS and control groups were given the same volume of saline.</p><p><b>RESULTS</b>The attenuated birth outcomes of the KDS group were displayed. The remarkable FT-IR differences of all organs between KDS mice and healthy control were mainly at 1,735-1,745 cm(-1) (indicating the increased levels of lipids) and at 1,640-1,647 cm(-1) and 1,539-1,544 cm(-1) (displaying the decreased proteins). No statistic FT-IR difference between Shenqi and control mice was observed.</p><p><b>CONCLUSION</b>In accordance with major traits of KDS, prenatal stress extensively impaired the building up of proteins and resulting in the excessive lipid storage, and FT-IR could effectively identify the biomarkers of KDS.</p>
