AIM: To set up a fingerprint analysis of Xintongning Capsules (Radix Notogenseng......) by TLC. METHODS: Silica gel G plate was adopted with developing underlayer of chloroform ethylacetate methanol water (15:40:22:10) under 10℃ resting overnight, 10% solution of H 2SO 4 in ethanol sprayed with and ginsenosides Rb 3 was used as standard substance. RESULTS: The result had 5 common spots. CONCLUSION: This method is accurate, reliable and provides a means for controlling the qualities of Xintongning Capsules.

【Objective】 To investigate the main causes of blood donor deferral in domestic blood center. 【Methods】 The causes of donor deferral were classified into 12 categories as previous medical history, drug use, alcohol consumption, menstrual period, underweight, abnormal blood pressure, abnormal body temperature, abnormal hemoglobin (Hb), lipemic blood, positive hepatitis B surface antigen (HBsAg), elevated alanine aminotransferase (ALT) and others according to the comparison indicators of Asia-Pacific Blood Network (APBN) and the national standard Blood Donor Health Examination Requirements. The relevant data of the top 3 causes of donor deferral, voluntarily reported by the members of Practice Comparison Working Group of China’s Mainland Blood Collection and Supply Institutions from 2014 to 2019, were collected and a histogram was generated. 【Results】 The median donor deferral rate of 20 domestic blood centers from 2014 to 2019 was 12.14%, with the lowest at 0.18% and highest at 32.32%, respectively. The top three causes for donor deferral were elevated ALT, abnormal Hb and abnormal blood pressure in year 2014, 2015, 2018 and 2019; elevated ALT, lipemic blood and abnormal blood pressure in 2016; elevated ALT, abnormal Hb, and lipemic blood in 2017. 【Conclusion】 The main causes of donor deferral were elevated ALT, abnormal Hb, abnormal blood pressure and lipemic blood.
