Résumé
OBJECTIVE:To establish the quality standards for Shenshuaikang granule. METHODS:TLC was used for the quali-tative identification of Astragali Radix and Rhei Radix et Rhizoma in the preparation. HPLC was used for the contents determina-tion of emodin and chrysophanol ,the column was Agilent HC-C18 with mobile phase of methanol-0.1% phosphoric acid (85:15 , V/V)at a flow rate of 1.0 ml/min,the detection wavelength was 254 nm,the column temperature was 30 ℃ and the injection vol-ume was 10 μl. RESULTS:TLC showed clear spots and good separation. The linear range was 1.9-60.8 μg/ml for emodin(r=0.999 9, n=6) and 1.6-51.2 μg/ml for chrysophanol (r=0.999 9),RSDs of precision,stability and reproducibility tests were lower than 3%,recoveries were 95.76%-103.66%(RSD=2.83%,n=9)and 97.24%-104.34%(RSD=2.65%,n=9),respectively. CONCLU-SIONS:The standard can be used for the quality control of Shenshuaikang granule.

Objective To investigate the association of interleukin-6 (IL-6) with depression using meta analysis. Methods A systematic literature search was conducted to examine depression and interleukin-6 in Chinese patients us-ing“depression”and“interleukin-6”in Databases including PubMed, CBM, VIP, CNKI and WanFang Data. A me-ta-analysis was performed to analyze correlation between depression and interleukin-6 using RevMan 5.2.8 software. Results A total of 9 studies were recruited, involving 432 depression patients and 277 healthy controls. The results of meta-analysis showed that concentration of IL-6 was higher in depression patients than in healthy controls(SMD=1.48, 95%CI:0.78~2.18,P<0.05). Subgroup analysis in the first-episode subgroup and the non first-episode subgroup showed that concentration of interleukin-6 was higher in depression patients than that in controls [the first-episode subgroup (SMD=1.94,95%CI:0.07~3.81,P<0.05), the non first-episode subgroup (SMD=1.26,95%CI:0.60~1.93,P<0.05)]. Conclusion There is a good correlation between depression and the serum IL-6 concentration. Due to the small number of studies and heterogeneity in different studies, the present meta-analysis has not yet confirmed the quantitative correla-tion between IL-6 and depression.

Objective To investigate an effective method of breathing apparatus management. Methods According to the defect in process of breathing machine management, breathing apparatus management center was set up, related standards and procedures were established, the staff training was intensified and the management mode was expanded. Results The qualified rate of ventilator sterilization and breathing apparatus function were improved to 100% by applying zero defect quality management. Conclusion It is an effective method to ensure the safety and accuracy in breathing machine manage- ment with applying zero defect quality management.
