【Objective】 To establish an intelligent management system of surgery blood (IMSSB) and explore its effectiveness in promoting rational and timely blood transfusion in surgical patients. 【Methods】 IMSSB was constructed based on the hospital closed-loop blood transfusion information management system, clinical transfusion mobile nursing APP system, and the Internet of Things blood bank forward management system to dynamically guide, supervise and evaluate the whole process of perioperative blood transfusion management. Blood management data of 100 patients undergoing cardiac vascular surgery before( from May to October, 2018) and after (from November 2018 to April 2019) the application of IMSSB were selected and compared to evaluate the role of the system in the management of surgical blood. 【Results】 Time, from blood application to transfusion, during surgery was shortened(30 minutes before vs less than 2 minutes after). The proportion of patients with Hb over 110g/L after intraoperative blood transfusion decreased significantly from 30.5%(25/82) to 8.5%(4/47)(P<0.01). The incidence of surgical blood transfusion decreased from 82.0%(82/100) to 47.0%(47/100)(P<0.01). 【Conclusion】 IMSSB, as an innovation of clinical blood management mode for surgical patients, can promote timely and rational blood transfusion during operation, which is of great significance to improve operation safety.

AIM: To investigate the effect of an effective component total sterone (TSR) of Echinops latifolius Tausch, the main component of a Chinese patent medicine Cuiru Keli (national drug standard WS3-413 (Z-085)-2003 (Z), on lactation and its possible mechanism. METHODS: After mating between male and female SD rats, 60 female rats were randomly divided into normal control group, model group, TSR low-dose and high-dose groups and prolactin granule positive control group, with 12 female rats in each group and 8 newborn rats in each nest. In addition to the normal control group, the rats in each group were intraperitoneally injected with levodopa 2 mg/kg once a day for 7 days from the second day of delivery. The rats in the normal control group were given normal saline by gavage once a day for 14 days. From the beginning of self-sufficiency, the single lactation of the female rats was measured every day until the 14th day, and then the female rats in each group were killed. Pathological HE staining was used to observe the morphological changes of mammary gland tissue in each group. ELISA was used to detect the levels of serum prolactin (PRL) and 5-hydroxytryptamine (5-HT). Immunohistochemistry was used to detect the distribution of PRL in mammary gland tissue of each group. Furthermore, Real-time qPCR was used to detect the expression of milk protein, milk fat related genes β-casein, FAS, ACC and the expression of canonical Wnt signaling pathway related genes β-catenin, c-Myc, CCND1, SFRP4, DNMT1, MeCP2 in mammary gland of each group. RESULTS: Both low and high dose TSR could significantly increase the single lactation volume, improve the pathological morphology of mammary gland, and increase the serum levels of PRL and 5-HT. TSR increased the distribution of PRL and up-regulated the expression of milk protein, milk fat related genes β-casein, FAS, ACC and canonical Wnt signaling pathway related genes β-catenin, c-Myc, CCND1, SFRP4, DNMT1, MeCP2.CONCLUSION: TSR can significantly promote lactation in lactation deficient rats, and its mechanism may be related to promoting the release of PRL and 5-HT in serum, increasing the distribution of PRL in mammary gland, up-regulating the milk protein and milk fat related genes and activating the canonical Wnt signal.

【Objective】 To explore and evaluate the application of blood intelligent management platform (scheme) based on the Internet of Things(IoT)in the clinical blood management for hospitals. 【Methods】 Based on radio frequency identification technology (RFID), smart blood refrigerators, IoT blood shipping containers, automated blood bank systems, smart blood management software, etc. were developed and integrated as an IoT blood intelligent management platform (scheme). The blood storage, management software and hardware systems were organically combined, and the blood storage equipment was moved forward to the clinical departments to solve the concerns of clinicians. 【Results】 The in-depth integration of IoT technology, RFID and refrigeration technology has built an RFID-based IoT blood management solution, which integrates blood storage, transfusion, and quality control management, also realizes the entire process of supervision and traceability of clinical blood transfusion. The forward movement of blood bank to the clinical departments and the implementation of electronic cross-matching streamlined and optimized the clinical blood flow. The waiting time of patient′s for blood transfusion was shortened from (40±10) min to less than 2 min. The whole process of cold chain logistics ensured the storage quality of blood products issued, so that the clinical departments can return the untransfused blood and Blood Transfusion Department can reissue it to other hospitals. 【Conclusion】 IoT blood intelligent management based on RFID realizes the intelligent management of clinical blood transfusion and blood information traceability. The forward movement of blood bank to the clinical departments improves the efficiency of clinical blood transfusion, avoids the waste of blood source, and ensures the safety of blood transfusion. It is worth promoting in the whole process of blood transfusion.
