AIM： Autologous blood donation （ABD） is mainly used to reduce the use of banked blood. In fact, ABD can be regarded as acute blood loss. Would ABD 2-3 d before operation affect the CVP level and subsequently result in less blood loss during liver resection was to be ***： Eighty-four patients undergoing living donor left hepatectomy were retrospectively divided as group Ⅰ （GⅠ） and group Ⅱ （GⅡ） according to have donated 250-300 mL blood 2-3 d before living donor hepatectomy or not. The changes of the intraoperative CVP, surgical blood loss,blood products used and the changes of perioperative hemoglobin （Hb） between groups were analyzed and compared by using Mann-Whitney ***： The results show that the intraoperative CVP changes between GⅠ （n = 35） and GⅡ （n = 49） up to graft procurement were the same, subsequently the blood loss,but ABD resulted in significantly lower perioperative Hb levels in ***： Since none of the patients required any blood products perioperatively, all the predonated bloods were discarded after the patients were discharged from the hospital. It indicates that ABD in current series had no any beneficial effects, in term of cost, lowering the CVP, blood loss and reduce the use of banked blood products, but resulted in significant lower Hb in perioperative period.

Boosting efficiency and stability of perovskite solar cells with nickel phthalocyanine as a low-cost hole transporting layer material

Journal of Materials Science & Technology 2018年第9期34卷 1474-1480页

作者： Mustafa Haider Chao Zhen Tingting Wu Gang Liu Hui-Ming cheng Shenyang National Laboratory for Materials Science Institute of Metal Research Chinese Academy of Sciences 72 Wenhua Road Shenyang 110016 China University of Chinese Academy of Sciences 19(A) Yuquan Road Beijing 100049 China School of Materials Science and Engineering University of Science and Technology of China 72 Wenhua Road Shenyang 110016 China Low-Dimensional Material and Device Laboratory Tsinghua-Berkeley Shenzhen Institute Tsinghua University 1001 Xueyuan Road Shenzhen 518055China Center of Excellence in Environmental Studies King Abdulaziz University Jeddah 21589 Saudi Arabia

The efficiency of perovskite solar cells（PSCs） has increased from around 4% to over 22% following a few years of intensive investigation. For most PSCs, organic materials such as 2,2＇,7,7＇-tetrakis（N,Npdimethoxyphenylamino）-9,9＇-spirobifluorene（spiro-OMeTAD） are used as the hole transporting materials（HTMs）, which are thermally and chemically unstable and also expensive. Here, we explored nickel phthalocyanine（NiPc） as a stable and cost-effective HTM to replace the conventionally used spiroOMeTAD. Because of its high carrier mobility and proper band alignments, we achieved a PCE of 12.1% on NiPc based planar device with short-circuit current density（Jsc） of 17.64 mAcm（-2）, open circuit voltage（Voc） of 0.94 V, and fill factor（FF） of 73%, outperforming the planar device based on copper phthalocyanine（CuPc） that is an outstanding representative of metal phthalocyanines（MPcs） reported. Moreover,the device with NiPc shows much improved stability compared to that based on the conventional spiroOMeTAD as a result of NiPc＇s high stability. Photoluminescence（PL） and Impedance spectroscopy analysis results show that thermally deposited NiPc has good hole-extraction ability. Our results suggest that NiPc is a promising HTM for the large area, low cost and stable PSCs.

Background: Complementary and alternative medicines are increasingly used for the treatment of asthma worldwide. A five-herb herbal formula (CUF) has been found to be effective and safe in an animal model of asthma and in a preliminary clinical study. Objective: The objective of this study was to evaluate the safety and efficacy of CUF in children suffering from asthma. Design: A randomized, double blind, and placebo-controlled, parallel study. Interventions: Subjects received CUF or placebo for 6 months. Efficacy variables included changes in forced vital capacity (FVC), forced expiratory volume in 1 s (FEV1), Paediatric Asthma Quality of Life Questionnaire (PAQLQ), and steroidal consumption. Results: A total of 100 asthmatic children were enrolled and assigned to two treatment groups. The first group received CUF 6 capsules (3 g/day) and the second group received placebo. There was a statistically significant difference in mean spirometric indexes in CUF group at baseline and follow-up visits. In the CUF group, the activity domain showed significant improvement (p = 0.045). FEV% was significantly improved in the CUF group (p strated. It improved the pulmonary functions of the children, namely, FEV1 and FVC. However, further research on a larger scale is warranted.
