Light propagation along the pericardium meridian at human wrist as evidenced by the optical experiment and Monte Carlo method / 中国结合医学杂志

<p><b>OBJECTIVE</b>To explore the characteristics of light propagation along the Pericardium Meridian and its surrounding areas at human wrist by using optical experiment and Monte Carlo method.</p><p><b>METHODS</b>An experiment was carried out to obtain the distribution of diffuse light on Pericardium Meridian line and its surrounding areas at the wrist, and then a simplified model based on the anatomical structure was proposed to simulate the light transportation within the same area by using Monte Carlo method.</p><p><b>RESULTS</b>The experimental results showed strong accordance with the Monte Carlo simulation that the light propagation along the Pericardium Meridian had an advantage over its surrounding areas at the wrist.</p><p><b>CONCLUSION</b>The advantage of light transport along Pericardium Merdian line was related to components and structure of tissue, also the anatomical structure of the area that the Pericardium Meridian line runs.</p>

Research on Zhejiang blood information network and management system / 中国实验血液学杂志

This research was aimed to develop the first level blood information centralized database and real time communication network at a province area in China. Multiple technology like local area network database separate operation, real time data concentration and distribution mechanism, allopatric backup, and optical fiber virtual private network (VPN) were used. As a result, the blood information centralized database and management system were successfully constructed, which covers all the Zhejiang province, and the real time exchange of blood data was realised. In conclusion, its implementation promote volunteer blood donation and ensure the blood safety in Zhejiang, especially strengthen the quick response to public health emergency. This project lays the first stone of centralized test and allotment among blood banks in Zhejiang, and can serve as a reference of contemporary blood bank information systems in China.

Application of microcolumn gel immunoassay in screening the platelet antibody / 中国实验血液学杂志

The purpose of this study was to explore the clinical value of the platelet antibody screening and typing in platelets transfusion by using microcolumn gel immunoassay (MGIA). The platelets antigen-antibody reactions including the antibody screen and blood crossmatch were detected by MGIA. The results indicated that the detection of platelet antibody showed positive in 30 cases of aplastic anemia (AA), 11 cases of myelodysplastic syndrome (MDS), 24 out of 25 cases of leukemia and 1 out of cases of other diseases, while detection of platelet antibody showed negative in 20 normal volunteer donors. The number of platelet antibody crossmatch coincidence in 112 specimens of AA, 42 specimens of MDS and 95 specimens of leukemia were 45, 20 and 40, the coincidence rates were 40.18%, 47.62% and 42.11%. The mean corrected count increment (CCI) in 20 patients received platelet transfusion many times was 18.2 after crossmatch and 4.7 before crossmatch. It is concluded that the positive rate of platelet antibody screening is very high in patients with hematologic malignancies, the coincidence rate of platelet antibody crossmatch in 249 blood samples is between 40% and 48%, and the efficiency of using crossmatched platelets in clinic is enhanced significantly.
