Objective To establish and evaluate an integrated disease-syndrome rat model of chronic cerebral ischemia with Qi deficiency and blood stasis syndrome.Methods Thirty male Wistar rats were allocated randomly into three groups(n=10 per group):sham operation(sham),2-vessel occlusion(2-VO)group,and sleep deprivation combined with 2-VO(SD+2-VO)group.We comprehensively assessed Qi deficiency and blood stasis syndrome manifestations in the rats using a dual evaluation approach,combining exhaustive swimming tests with quantitative tongue chroma analysis.Cognitive function was evaluated using the Barnes maze,and cerebral blood flow was compared using laser speckle contrast imaging.The histopathology of the hippocampal cytoarchitecture and white matter were examined using hematoxylin-eosin(HE)and Luxol fast blue(LFB)staining,respectively,and ultrastructural alterations of neurons in the hippocampal CA1 region were observed by transmission electron microscopy(TEM).Protein expression levels of NeuN,vascular endothelial growth factor A(VEGFA)and CD31 were detected by Western Blot and immunofluorescence.Results Cerebral blood flow was significantly reduced in rats in the 2-VO group compared with the sham group,but they failed to recapitulate the key clinical hallmarks of Qi deficiency and blood stasis syndrome.In contrast,rats in the SD+2-VO group exhibited significantly reduced locomotor activity,exacerbated cerebral hypoperfusion,shortened swimming duration,and darkened tongue color compared with 2-VO rats.Rats in the SD+2-VO group demonstrated significantly impaired learning and memory abilities in the Barnes maze test.Consistent with these observations,HE staining,TEM,and LFB staining revealed substantial neuronal and white matter damage in the SD+2-VO group.NeuN expression was decreased and VEGFA and CD31 expression levels were increased in the 2-VO and SD+2-VO groups,as shown by Western Blot.Taken together,these findings indicated that the SD+2-VO model effectively recapitulated the clinical features of chronic cerebral ischemia with Qi deficiency and blood stasis pattern.Conclusions The combination of sleep deprivation and bilateral carotid artery occlusion successfully established a rat model of chronic cerebral ischemia with Qi deficiency and blood stasis syndrome.Compared with the 2-VO model,SD+2-VO model demonstrates more pronounced syndrome manifestations and better clinical relevance,thus providing a valuable animal model for traditional Chinese medicine research on chronic cerebral ischemia.

Objective? To explore the effects of fast track surgery (FTS) nursing on fatigue and quality of life among hepatocellular carcinoma patients. Methods? From June 2017 to June 2018, we selected 80 primary hepatic carcinoma patients with hepatocellular carcinoma resection of hepatobiliary surgery at Peking Union Medical College Cancer Hospital as subjects by convenience sampling. All of the patients were divided into control group and observation group with the method of random number table, 40 cases in each group. Observation group carried out FTS, while control group adopted routine nursing. The intervention effects were compared with the Cancer Fatigue Scale (CFS) and the Quality of Life Questionnaire Core 30 (QLQ-C30). Results? Before intervention, there was no statistical difference in the score of CFS between two groups (P＞0.05). After intervention, the total score and dimension scores of CRF of observation group were lower than those of control group with statistical differences (P＜ 0.01). Before intervention, there was no statistical difference in the score of QLQ-C30 between two groups (P＞ 0.05). After intervention, the total score of QLQ-C30 of observation group was higher than that of control group with a statistical difference (P＜ 0.01). Conclusions? FTS can effectively improve the postoperative fatigue of hepatocellular carcinoma patients and quality of life of patients which is worthy of clinical popularization and application.
