Objective In order to improve blood donors to understand the health education knowledge,this study designed and evaluated a new project,that is the health education pathway for primary apheresis donors.Methods A total of 2900 primary apheresis donors participated in the current study,who were randomly divided into the experimental group and the control group.The experimental group was performed the health education pathway for primary apheresis donors,while the control group was conducted in the traditional health educational ways.We compared the basic information,the awareness rate of apheresis donation knowledge,the number of regnlar/repeated donors,and the frequency of donations.Results Two groups were matched with no group differences in basic information (P＞0.05).After performed the health education pathway for primary apheresis donors,the awareness rate of apheresis donation knowledge was significantly improved from 23.6％ to 84.3％ (P＜0.01).Moreover,the percentage of regular donors (40.2％) in the experimental group higher than the percentage (26.7％) in the control group(P＜0.01).The average donation times of experimental group (3.8) was also higher than the control group.There were 79.2％ donors changed to regular/repeated donors higher than the percentage (66.4％) in the control group,and the average frequency of apheresis of those regular/repeated apheresis donors (7.4) in the experimental group higher than the control group (6.4) (P＜0.01).Conclusion As showed in our results,the health education pathway for primary apheresis donors could effectively help donors to understand the knowledge of blood donation and health care,and promote team construction of regular donors.We hope,in the future,the health education pathway for primary apheresis donors could be widely spread.

Objective To investigate the quality of concentrated platelet with less WBC by improved white membrane method,so as to provide the basis for preparation of the concentrated platelet in the future.Methods Testing the quality indicators of 56 cases of concentrated platelet with less white blood cells by improved white membrane method,and comparing the quality indicators of 56 cases of collected platelet at random by machine.Testing the expression rate of platelet membrane surface glycoprotein molecules CD62P and PAC-1 before and after filtering in different storage time,and comparing the expression rate of 37 cases of collected platelets at random by machine.Results The differences of quality indicators between concentrated platelet with less white blood cells by improved white membrane methods and collected platelet at random by machine were not statistically significant (P＞0.05),such as volume,platelet content,Ph,amount of RBC mixed within.But The differences of amount of WBC mixed with were statistically significant (P＜ 0.01),both of sterility tests were negative.The differences of the expression rate of platelet membrane surface glycoprotein molecules CD62P and PAC-1 during storage period within 3 days were not statistically significant (P＞0.05).Conclusion The various quality indicators of concentrated platelet with less white blood cells by improved white membrane methods attain mixed concentrated platelet and platelet national standards,and in vitro platelet activity kept well.Platelet special leucocyte filter does not cause obvious platelet activation and damage within three days of storage period of concentrated platelet in filter processing.Collected platelet by machine is being activated and damaged continuously when kept in platelet oscillation device 22±2℃ for 3 days,but activation and damage does not significantly change the platelet activity in vitro.

Gei Herba is a traditional folk herbal medicine with a variety of functions such as replenishing Qi and invigorating spleen， tonifying blood and nourishing Yin， moistening lung and resolving phlegm， activating blood and alleviating edema， moving Qi， and activating blood. The reports about the pharmacological effects of this herbal medicine have been increasing in recent years. By reviewing the ancient and modern literature about Gei Herba， we systematically organized the name， original plants， nature， taste， and functions of this herbal medicine， and summarized the modern pharmacological studies and clinical applications of Gei Herba in cardiovascular and cerebrovascular diseases. Gei Herba was first recorded in the name of "Dijiao" in the Geng Xin Yu Ce（《庚辛玉册》） written in the Ming Dynasty. It is derived from Geum japonicum var. chinense （Rosaceae） and sometimes confused with Adina rubella （Rubiaceae）. This medicine had numerous synonyms in the local materia medica books. Gei Herba is widely distributed and harvested in summer and autumn， with the dried whole grass used as medicine. The historical records of the nature， taste， meridian tropism， main functions， and indications of Gei Herba are not consistent. It is generally believed that Gei Herba is pungent， bitter， sweet， cool， and has tropism to the liver， spleen， and lung meridians. Based on the effects of tonifying Qi， activating blood， and nourishing Yin， modern pharmacological studies have reported that the extracts of Gei Herba and the tannin phenolic acid compounds and triterpenoids isolated from Gei Herba have therapeutic effects on cardiovascular and cerebrovascular diseases such as hypertension， myocardial ischemia， cerebral ischemia， and vascular dementia. This study provides a reference for discovering the clinical advantages of Gei Herba and developing new drugs.

ObjectiveBased on ultra performance liquid chromatography-quadrupole-electrostatic field orbital trap high-resolution mass spectrometry（UPLC-Q-Orbitrap-MS）， to identify the in vivo and in vitro chemical components of total phenolic acids in Gei Herba（TPAGH）， and to clarify the pharmacological effects and potential mechanisms of the effective part in promoting acute wound healing and inhibiting scar formation. MethodsUPLC-Q-Orbitrap-MS was used to identify the chemical components of TPAGH and ingredients absorbed in vivo after topical administration. A total of 120 ICR mice were randomly divided into the model group， recombinant human epidermal growth factor（rhEGF） group（4 mg·kg^-1）， and low， medium， and high dose groups of TPAGH（3.5， 7， 14 mg·kg^-1）， with 24 mice in each group. A full-thickness skin excision model was constructed， and each administration group was coated with the drug at the wound site， and the model group was treated with an equal volume of normal saline， the treatment was continued for 30 days， during which 8 mice from each group were sacrificed on days 6， 12， and 30. The healing of the wounds in the mice was observed， and histopathological changes in the skin tissues were dynamically observed by hematoxylin-eosin（HE）， Masson， and Sirius red staining， and enzyme-linked immunosorbent assay（ELISA） was used to dynamically measure the contents of interleukin-6（IL-6）， tumor necrosis factor-α（TNF-α）， vascular endothelial growth factor A（VEGFA）， matrix metalloproteinase（MMP）-3 and MMP-9 in skin tissues. Network pharmacology was used to predict the targets related to the promotion of acute wound healing and the inhibition of scar formation by TPAGH， and molecular docking of key components and targets was performed. Gene Ontology（GO） biological process analysis and Kyoto Encyclopedia of Genes and Genomes（KEGG） pathway enrichment analysis were carried out for the related targets， so as to construct a network diagram of herbal material-compound-target-pathway-pharmacological effect-disease for further exploring its potential mechanisms. ResultsA total of 146 compounds were identified in TPAGH， including 28 phenylpropanoids， 31 tannins， 23 triterpenes， 49 flavonoids， and 15 others， and 16 prototype components were found in the serum of mice. Pharmacodynamic results showed that， compared with the model group， the TPAGH groups showed a significant increase in relative wound healing rate and relative scar inhibition rate（P<0.05）， and the number of new capillaries， number of fibroblasts， number of new skin appendages， epidermal regeneration rate， collagen deposition ratio， and Ⅲ/Ⅰ collagen ratio in the tissue were significantly improved（P<0.05， 0.01）， the levels of IL-6， TNF-α， MMP-3 and MMP-9 in the skin tissues were reduced to different degrees， while the level of VEGFA was increased. Network pharmacology analysis screened 10 core targets， including tumor protein 53（TP53）， sarcoma receptor coactivator（SRC）， protein kinase B（Akt）1， signal transducer and activator of transcription 3（STAT3）， epidermal growth factor receptor（EGFR） and so on， participating in 75 signaling pathways such as advanced glycation end-products（AGE）-receptor for AGE（AGE/RAGE） signaling pathway， phosphatidylinositol 3-kinase（PI3K）/Akt signaling pathway， mitogen-activated protein kinase（MAPK） signaling pathway. Molecular docking confirmed that the key components genistein， geraniin， and casuariin had good binding ability to TP53， SRC， Akt1， STAT3 and EGFR. ConclusionThis study comprehensively reflects the chemical composition of TPAGH and the absorbed components after topical administration through UPLC-Q-Orbitrap-MS. TPAGH significantly regulates key indicators of skin healing and tissue reconstruction， thereby clarifying its role in promoting acute wound healing and inhibiting scar formation. By combining in vitro and in vivo component identification with network pharmacology， the study explores how key components may bind to targets such as TP53， Akt1 and EGFR， exerting therapeutic effects through related pathways such as immune inflammation and vascular regeneration.
