Shanghai expert consensus on remote verification system of blood distribution in medical institutions / 中国输血杂志

In order to solve the difficulties and challenges in the implementation of the original blood distribution and collection regulations caused by the expansion of hospital area, the extension of blood transfer time, the changeability of blood transfer environment, and the strain of personnel due to the increase of workload, as well as to ensure the accuracy of the information throughout blood remote verification and distribution and the safety of clinical blood transfusion, , Shanghai experts related to clinical transfusion and blood management had made a systematic study on the applicable scope and management rules of remote verification of blood distribution and collection, and formulated this Expert Consensus combined with the development status of digital, intelligent and remote communication technologies, so as to provide corresponding guidance for clinical medical institutions in line with the changes in reality.

Treatment of bone defect in hip revision / 生物医学工程学杂志

To investigate the option of treatments for bone defect in femoral revision after total hip replacement (THR), 29 patients (29 hips) who had undergone hip replacement 13.7 years previously were hospitalized again to undergo revisions. 3 patients were given cement protheses and the other 24 patients were given non-cement protheses. In 3 cases were used Synergy+Reflection protheses, and in the others were used CLS +ALLOFIT. All of the patients have got primary healing without early infection symptoms post-operatively. We have been following up 25 cases (25 hips) for 58 months averagely. All the hip joints functioned well. Harris score increased from preoperative 36.8 to postoperative 93.2. In our experience, if there exist significant bone defect in acetabular bone and the coverage of the cup by the graft is more than 80%, bone graft is not needful. If the coverage is between 50% and 80%, bone grains combining bone segment grafts are needful. If the coverage is less than 50%, bone segment grafts be likely to give good effect. In summary, compacted bone grains grafts combining allograft osintegumentale plate could gain satisfactory outcome for femoral bone defect.

Intercedenol A and B,two new triterpenoid aglycones from the acid hydrolysis of the glycoside mixture of the sea cucumber Mensamaria intercedens / 中国海洋药物

Objective To study the aglycone of the saponins from Mensamaria intercedens.Methods Complete acid hydrolysis of the glycoside mixture of the sea cucumber with 15%(H_(2)SO_(4))afforded an aglycone product that was separated by multichromatography and their chemical structures were elucidated by chemical and spectral analyses.Results Two compounds were obtained and identified as 16?-acetoxy-9(11),22(23) E,24(25)-3?-hydroxyholost(Ⅰ),16?-acetoxy-8(9),22(23) E,24(25)-3?-hydroxyholost(Ⅱ).Conclusion Two compounds are new triterpenoids.
