ObjectiveStudies have shown that nuciferine has anti-cerebral ischemia effect， but the specific mechanism of action has not been elaborated. Based on the transcriptome results， the pharmacological mechanism of nuciferine against cerebral ischemia was analyzed from multiple dimensions including tissue， cell， pathological process， biological process and signaling pathway. MethodsThirty SD rats were randomly divided into the sham group， model group and nuciferine group（40 mg·kg^-1） according to weight. Except for the sham group， the model of middle cerebral artery occlusion（MCAO） was established by thread embolization method after 30 min of administration in the other two groups. Twenty-four hours after surgery， transcriptome sequencing was used to detect the gene expression profiles in the cortex penumbra of rat cerebral tissue， and gene ontology（GO） and kyoto encyclopedia of genes and genomes（KEGG） pathway enrichment analysis were performed for differentially expressed genes. The mechanismof nuciferine against cerebral ischemia was analyzed from 5 dimensions of tissue， cell， pathological process， biological process and signaling pathway by the transcriptome-based multi-scale network pharmacology platform（TMNP）. ResultsTranscriptome sequencing and gene quantitative analysis showed that 667 genes were significantly reversed by nuciferine. Further enrichment analysis of KEGG and GO suggested that the pathways of nuciferine involved regulating stress response， ion transport， cell proliferation and differentiation， and synaptic function. TMNP research found that at the tissue level， nuciferine could significantly improve the cerebral tissue injury caused by ischemia. At the cellular and pathological levels， nuciferine could play an anti-cerebral ischemia role by improving the state of various nerve cells， mobilizing immune cells， regulating inflammation. And at the level of biological processes and signaling pathways， nuciferine mainly acted on the processes such as vascular remodeling， inflammation-related signaling pathways， and synaptic signaling. ConclusionCombined with the results of transcriptome sequencing， gene quantitative analysis and TMNP， the mechanism of nuciferine against cerebral ischemia may be related to processes such as intervening in stress response and inflammation， affecting vascular remodeling and regulating synaptic function. These results can provide a basis and reference for further study of the pharmacological mechanism of nuciferine against cerebral ischemia.

There were statistically significant differences between the two groups ( t values were 4.30, 5.01, P < 0.05); family care scores of the two groups were compared, the intervention group was 8.78±2.04. The control group was 8.43±2.05. There were statistically significant differences between the two groups ( t value was 2.02, P < 0.05); the comprehension support score of the two groups was compared, and that of the intervention group was 62.24±14.81. The control group was 55.74±13.58. There were statistically significant differences between the two groups ( t value was 4.26, P < 0.05). Conclusion:Peer support education can improve the quality of life and family care of breast cancer patients with breast reconstruction.

Objective:To explore the occurrence of symptoms in postoperative patients with oral cancer, and to explore the types and number of symptom groups.Methods:The Anderson symptom assessment scale for head and neck cancer was used to conduct a questionnaire survey on 345 patients after oral cancer surgery. The results of two exploratory factor analysis methods were compared, and the cluster analysis and Spearman rank correlation analysis were combined to determine the symptom group of patients after oral cancer surgery.Results:There were 4 symptom groups in patients with oral cancer, including oral and pharynx symptoms group, dietary and digestive symptoms group, gastrointestinal and emotional symptoms group, and rest activity symptoms group.Conclusions:There are many symptom groups that affect the life of patients with oral cancer in the rehabilitation process after surgery, so the medical staff should carry out targeted intervention mode to achieve better intervention effect.

Objective:To investigate the symptoms of patients with oral cancer during treatment, and explore the types of symptom groups and their correlation with quality of life.Methods:Totally 201 patients with oral cancer after surgery were selected as the subject from a ClassⅢ Grade A hospital using convenient sampling and investigated with the MD Anderson Symptom Inventory for Head and Neck cancer (MDASI-HN) and University of Washington Quality of Life Questionnaire (UW-QOL) , and explore the relationship between them.Results:Totally 189 patients completed the questionnaire. Patients with oral cancer showed many symptoms during the progression and treatment of the disease. Serious symptoms included swallowing, chewing and speaking. Exploratory factor analysis revealed three symptom groups, namely, oral and throat symptom group, drowsiness-digestive tract symptom group, and fatigue-respiratory symptom group. The scores of different dimensions and the total scores of quality of life were negatively correlated with the total scores of the three symptom groups ( P<0.05) . Conclusions:There are multiple symptom groups in patients with oral cancer during postoperative rehabilitation, which seriously affect their quality of life. Medical workers should grasp this characteristic, evaluate symptoms in time, actively manage symptom groups, and improve the quality of life of patients.

Objective: To explore the basic conditions and postoperative quality of life in patients undergoing oral vestibular thyroid surgery. Methods: A total of 128 patients undergoing oral vestibular thyroid surgery were enrolled in the Department of Head and Neck Surgery from March 2015 to April 2018. On the basis of routine thyroid tumor care, we used telephone, WeChat public platform, WeChat group, QQ, and Email. Questionnaires such as information technology and clinic review. Correlation analysis was performed using SPSS 22.0.

Objective: To evaluate the therapeutic effect and security of Buyang Huanwu decoction in treatment of the ischemic stroke recovery. Methods: We retrieved the relevant articles of random and semi- random control trials in treating ischemic stroke recovery using Buyang Huanwu decoction, published in China National Knowledge Infrastructure (CNKI), the Wanfang Data, the Weipu Information Resources System, the Chinese Biomedical Literature Database (CBM), Cochrane Library, PUBMED and MEDLINE from the date of establishment until to March 2018. The quality of studies was evaluated according to the Cochrane Reviewers?? handbook 5.1, and the study was carried out using Cochrane system assessment methods. Statistical analysis was performed with Rev Man 5.3. Results: Altogether 39 studies and 3539 cases of ischemic stroke recovery were enrolled. In terms of clinical efficacy, the difference between Buyang Huanwu Decoction and Western Medicine conventional therapy in the treatment of ischemic stroke was significantly different from that of conventional western medicine therapy [RR =1.26, 95％CI (1.20, 1.31), Z =10.05, P ＜ 0.00001], and the difference between Buyang Huanwu Decoction and other Chinese patent medicines was statistically significant [RR =1.12, 95％CI(1.06, 1.19), Z =3.82, P =0.0001]; neurological deficit NIHSS score [MD =-2.55, 95％CI (-3.10, -2.01), Z =9.20, P ＜ 0.00001]; clinical neurological deficit score (CSS) [MD =-3.85, 95％CI (-5.21, -2.50), Z =5.56, P ＜ 0.00001]; limb motor function score (FMA) [MD =6.10, 95％CI (1.19, 11.01), Z =2.43, P =0.01]; Barthel Index of Daily Living Activity Scale [MD =9.09, 95％CI (6.95, 11.23), Z =8.33, P ＜ 0.00001]; In terms of improving blood rheology index, serum peroxide lipid (LPO), serum superoxide dismutase (SOD) and other biochemical indicators, due to the small number of studies, it may have a certain effect. Most studies did not report adverse reactions. Conclusion: Based on the existing clinical evidence, combination of Buyang Huanwu decoction and western medicine has higher clinical efficacy than western medicine alone for the ischemic stroke recovery. Due to the limited methodological quality of the included studies, more high- quality RCTs with large scale are needed to increase the strength of the above evidence.
