Objective To establish a cell line and a convenient and well-duplicated minimal residual leukemia (MRL) model. Methods We chose the international standard domestic inbred DBA/2 mouse to inoculate the different numbers of L1210 leukemic cells to investigate the relationship between inoculating cell number and mouse survival time. On the third day after 1×106 leukemic cells per mouse were inoculated, different doses of CTX were used for the chemotherapy. Results The inoculating number of L1210 leukemic cells increased while the mouse survival time decreased;The survival time increased following the increase of the doses of the CTX;The survival time of the inoculated mouse treated with CTX at 125 mg/kg was equal to that of the mouse inoculated with 500 L1210 leukemic cells without treatment. Conclusion The observation results are that the dose of 125 mg/kg for creating the model of MRL mouse.

Objective To know the postnatal depression and anxiety state and its related factors of parturients from migrant worker family,and then reference to certain nursing counter-measures. Methods Sampled 73 parturients by spontaneous labor from migrant worker family and 45 local matched parturients,interviewed them by SAS and SDS to know their postnatal depression and anxiety state,and then analyzed the datum between them. Results The level of postnatal depression and anxiety in parturients from migrant worker family was significant higher than that in local parturienta.Different level of depression and anxiety was existed in different parturients from migrant worker family by different educational attainments,different family type and different financial state. Conclusions The state of postnatal depression and anxiety in parturients from migrant worker family is severely,related health education should be strengthened,associated social secu-rity and support system should be established to help them release their unhealthy emotion.

Objective:To explore the application of photoplethysmography (iPPG) for contactless vital signs monitoring in the intensive care unit (ICU).Methods:Ten tracheostomy patients in intensive care had their heart rate, oxygen saturation, and diastolic and systolic pressures monitored using iPPG technology and a 24-hour bedside monitor. The readings included periods at rest, during turning, during suctioning, and when undergoing vigorous physical therapy and occupational therapy. The monitoring lasted 3 consecutive days. The data collected by the two methods were compared to analyze the accuracy of the contactless vital signs monitoring system.Results:The oxygen saturation readings of the two systems showed no significant differences. The heart rates, diastolic pressures, and systolic pressures did, however, differ significantly.Conclusions:In the situations tested, contactless monitoring of oxygen saturation is effective, but there is still significant room for improvement in the three indicators of heart rate, systolic pressure, and diastolic pressure.
