Through analyzing medical personnel's duty under Bio-psycho-social Medical Mode, this paper states that medical personnel's duty should be emphasized not only on preventing and curing diseases, but also on solving patients' psychological problems.Therefore it states that death education, first, to medical professionals themselves,second,to the patients and their family,is very important,at last it also inquires into the mode of death education.

OBJECTIVE To investigate the effects of the compo nents of traditional Chinese medicine （TCM）（total ginsenoside，total ketone ester of Ginkgo biloba ，total glucoside of Crocus sativus ）for invigorating qi and activating blood circulation on cognitive function of mice with chronic cerebral ischemia （CCI）and its related mechanisms . METHODS CCI model was established by stimulating bilateral common carotid arteries of C 57BL/6J mice with temperature controlled current . Model mice were randomly divided into model group ，aspirin group （positive control 10 mg/kg）and TCM group （the components of TCM for invigorating qi and activating blood circulation 33 mg/kg），sham operation group was set up additionally ，with 16 mice in each group. Except that the mice in model group and sham operation group were given water intragastrically ，the mice in the other groups were given corresponding medicine liquid intragastrically，once a day ，for 8 weeks. The latency of step down and the number of step -down errors of mice in each group were detected ；the ultrastructure of neurovascular units（NVU）in cerebral cortex and hippocampus was observed ；the protein and mRNA expressions of vascular endothelial growth factor（VEGF）and α7 nicotinic acetylcholine receptors （α7nAChRs） in cerebral tissue were detected ；the contents of VEGF，angiopoietin 1 （Ang1） and basic fibroblast growth factor（bFGF）were detected . RESULTS Compared with model group ，the latency of step -down was significantly prolonged （P＜ 0.05），and the number of step -down errors was significantly reduced （P＜0.05）in TCM group . The ultrastructural abnormalities of NVU in cerebral cortex and hippocampus were significantly improved ，and the protein and mRNA expressions of VEGF and α7 nAChRs and the contents of VEGF ，Ang1 and bFGF in cerebral tissue were significantly increased （P＜0.05）. CONCLUSIONS The components of TCM for invigorating qi and activating blood circulation can improve CCI -induced cognitive dysfunction in mice，the mechanism of which may be associated with protecting NVU ，recovering ultrastructural abnormalities of injured NVU ， and regulating the expression of proteins closely related to NVU and memory function .

OBJECTIVE: To evaluate the value of neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) for assessing disease activity in patients with rheumatoid arthritis (RA) treated with tofacitinib. METHODS: This retrospective study was conducted among 98 RA patients in active stage treated with tofacitinib in Third Xiangya Hospital and 100 healthy control subjects from the Health Management Center of the hospital from 2019 to 2021. We collected blood samples from all the participants for measurement of erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), interleukin-6 (IL-6) and other blood parameters 1 month before and 6 months after tofacitinib treatment. We further evaluated PLR and NLR before and after tofacitinib treatment in the RA patients, and analyzed their correlations with RA disease activity. RESULTS: PLR and NLR increased significantly in RA patients as compared with the healthy controls. In the RA patients, PLR and NLR were positively correlated with the levels of hs- CRP, ESR, IL- 6, Disease Activity Score of 28 joints-ESR (DAS28-ESR), anti-cyclic citrullinated peptide (CCP), and rheumatoid factor (RF) before and after tofacitinib treatment. Tofacitinib treatment for 6 months significantly decreased hs-CRP, ESR, IL-6, CCP, RF and DAS28-ESR levels in the RA patients. CONCLUSION NLR and PLR can be useful biomarkers for assessing disease activity in RA patients treated with tofacitinib.
