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.

Objective:To elucidate the primary elements pertaining to the perception of relapse risk and to in-vestigate the characteristics and alterations of perception of the risk of recurrence in patients with schizophrenia.Methods:By using the method of phenomenological study,semi-structured in-depth interviews were conducted among schizophrenic patients with first onset,first recurrence and multiple recurrences.Twenty-three 23 outpatient and inpatient cases that met the criteria of the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition(DSM-5)were included,and all patients had PANSS scores below 60.The interview data were collated and analyzed according to Colaizzi analysis.Results:The perception of recurrence risk in patients with schizophrenia en-compassed 4 major themes and 11 sub-themes,namely susceptibility(limited overall understanding,transition from optimism to objectivity),detection of early warning symptoms(dynamic escalation,assistance from family mem-bers in identification),understanding risk factors(lack of understanding,the relationship between psychosocial fac-tors and relapse,dynamic understanding of medication-relapse relationship),and apprehension of the consequences of recurrence(care burden and financial constraints,impaired social functioning and maladjustment,impact on pub-lic safety,personal health risks).Conclusion:The content of risk perception of recurrence in patients with schizo-phrenia is relatively substantial.The overall level of risk perception of recurrence in patients with schizophrenia is low.

Objective To conduct lipidomics analysis of medical Marmota himalayana oil and explore its potential biological effects. Methods Marmota himalayana abdominal fat was heated and refined to produce medical marmot oil. Lipidomics analysis of two batches of Marmota himalayana oil was performed using gas chromatography-mass spectrometry (GC-MS) and ultra-high performance liquid chromatography-mass spectrometry (UPLC-MS). The potential effects of Marmota himalayana oil were analyzed based on the results of lipid composition detection. Results GC-MS results showed that the main components of the two batches of Marmota himalayana oil were saturated fatty acids (volume fraction of about 60%) and unsaturated fatty acids (volume fraction of about 30%). The saturated fatty acids were mainly palmitic acid, stearic acid, and arachidic acid, while the unsaturated fatty acids were mainly oleic acid and linoleic acid. There were no significant differences in the volume fraction of various fatty acids between the two batches, indicating that the preparation process of Marmota himalayana oil was stable. The results of UPLC-MS negative ion mode detection showed that Marmota himalayana oil contained 15 saturated fatty acids and 18 unsaturated fatty acids, but there were significant differences in volume fraction between the two batches. The results of UPLC-MS positive ion mode detection showed that Marmota himalayana oil of both batches contained 15 diglycerides and 30 triglycerides. Conclusion This study innovatively applies GC-MS and UPLC-MS techniques to analyze the lipidomic components of medical Marmota himalayana oil, providing a reliable basis for subsequent exploration of its pharmacological activity and the establishment of strict quality control standards.

Objective In order to explore the effect of 25-(OH)D3 on monocyte chemoattratant protein (MCP)-1 expression from patients with system lupus erythematosus (SLE),we detected the level of active vitamin D and the expression of MCP-1 mRNA in patients with SLE,and analyzed the correlation between them.Methods The level of serum 25-(OH)D3 and mRNA expression of MCP-1 in 154 SLE patients and 31 healthy individuals were detected by enzyme-linked immuno sorbent assay (ELISA) and real time quanti-tative pol ymerase chain reaction (PCR) respectively.We also analyzed the correlation between serum 25-(OH)D3 level and the expression of MCP-1 mRNA,then analyzed the function of 25(OH)D3 on the regula-tion of MCP-1 mRNA expression in vitro.The differences between the two groups were tested by t-test and x2 test,multiple data were tested by one-way ANOVA and the correlation was analyzed by Pearson's correlation,all data were analyzed by statistical product and service solutions (SPSS) 17.0 software.Results The serum 25(OH)D3 levels in SLE group (20±11) ng/ml was significantly lower than normal control group (29±11) ng/ml (t=4.198,P＜0.01),and the ratio of the serum levels of vitamin D deficiency in SLE group were significantly higher than that of normal control group [55.8％(86/154) vs 22.6％(7/31),x2=11.421,P=0.001].The expression level of MCP-1 mRNA in PBMCs from the normal control group was significantly lower than the SLE group (1.14±0.27 vs 1.44± 0.31,t=3.277,P=0.001),serum 25(OH)D3 level and MCP-1 mRNA expression in patients with SLE PBMCs were significantly negatively correlated (r=-0.289,P＜0.01).Further study found that 25-(OH)D3 inhibited MCP-1 mRNA expression in PBMCs from SLE patients depending on the concentration.Conclusion The decreased 25-(OH)D3 level and up-regulated MCP-1 mRNA expression suggestthat MCP-1 may play an important role in SLE pathological process.

Objective To investigate the effects of age and gender on anti-oxidative,antiinflammatory and anti-apoptosis functions of high-density lipoprotein (HDL).Methods Totally 120 healthy subjects aged from 20 to 60 years were randomly divided into young and middle-aged male (n=60) group and female (n =60) group,and the 120 healthy elderly aged from 60 to 78 years divided into elderly male (n =60) and elderly female (n =60) groups.Serum levels of high-and low-density lipoprotein cholesterol (HDL-C,LDL-C),total cholesterol (TC),and triacylglycerol (TG) were detected.Content of malonaldehyde (MDA) was detected to determine anti-oxidative function of HDL.Adhesion assay of endothelial cells and monocytes (THP1) was adopted to test the protective effects of HDL on endothelial cells.The expressions of endothelial cell adhesion molecules,VCAM-1 and ICAM-1,were analyzed by Western blot.MTT and flow cytometry assays were used to detect the viability and apoptosis of the cells to test anti-apoptosis function of HDL.Results The levels of low-density lipoprotein,triglycerides and total cholesterol were higher in elder female group than in other three groups (all P＜0.05).The level of HDL-C was higher in young and middle-aged females than in other three groups(all P＜0.05).The level of MDA was higher in elder female group than in other three groups(all P＜0.05).The level of MDA was higher in elder male group than in the young and middle-aged male and female groups(all P＜0.05).After protection of HDL,the number of monocytes adhesion and expression levels of VCAM-1 and ICAM-1 were higher in elder groups than in young and middle-aged male and female groups(all P＜ 0.05).Relative survival and viability rates of endothelial cells were higher in young and middle-aged groups than in elder groups (all P＜0.05).Conclusions Ageing in both male and female induces impairments of anti-oxidative,anti-inflammatory and anti-apoptosis functions of HDL,with more evident decrease in anti-oxidative function in females.

Objective To observe the effect of JLP deficiency on the progression of renal interstitial fibrosis in mice model of unilateral ureteral obstruction (UUO),and to investigate the role and underlying mechanism of JLP in the development of renal fibrosis in obstructive nephropathy.Methods jlp Wild type (jlp+/+) and jlp deficient (jlp-/-) mice were divided into four groups:jlp+/+-and jlp-/--sham-operated groups(jlp-/--sham group and jlp+/+-sham group),jlp+/+-and jlp-/--unilateral ureteral obstruction (UUO)-operated groups (jlp/--UUO group and jlp+/+-UUO group).Mice were sacrificed at 7 days and 14 days after the operation respectively to evaluate the fibrosis by Masson staining.The expression of JLP in jlp +/+ renal tissue was assayed by immunohistochemistry staining,immunofluorescence and Western blotting.Immunohistochemical staining was used to detect the expression of α-smooth muscle actin (α-SMA),collagen Ⅰ (COL-Ⅰ),collagen Ⅲ (COL-Ⅲ) and transforming growth factor-β1 (TGF-β1) in sham and UUO groups.Besides,the α-SMA,COL-Ⅰ,COL-Ⅲ,TGF-β1,p-Smad2 and p-Smad3 protein levels were also analyzed by Western blotting in four groups.Results The expression of JLP was mainly demonstrated in the renal tubules of mice.A large amount of collagen deposition was observed in the renal interstitial area in jlp-/--UUO group compared to jlp+/+-UUO group.Similarly,the expression of α-SMA,COL-Ⅰ,COL-Ⅲ and TGF-β1 was significantly increased in the kidney cortices in jlp-/--UUO-operated groups.Meanwhile,Western blotting showed that the expression of α-SMA,COL-Ⅰ,COL-Ⅲ,and TGF-β1 protein was obviously higher in jlp-/--UUO group.Moreover,the expression of p-Smad2 and p-Smad3 protein was markedly higher in jlp-/--UUO group.Conclusion Scaffolding protein JLP is critical in preventing renal fibrosis through the inhibition of TGF-β1 expression and myo-fibroblast production.

Objective To study the relationship between injury site (right or left) or pathological type (hemorrhage or infarct) and atten-tion impairment in post stroke cognitive impairment (PSCI). Methods June, 2014 to June 2015, 49 patients with PSCI were assessed with Test of Attentional Performance (TAP) within 1 week of admission. The reaction time and the numbers of correct response were recorded. Results The reaction time of alertness (with or without alarm) was shorter in the patients with left infarction (Z=-2.32, t=-3.76, P<0.05), and the correct number of auditory was more (Z=2.42, P<0.05) than those with right infarction. The reaction time of incompatibility test and Go/Nogo test was shorter in patients with left hemorrhage than those with right hemorrhage (Z>2.32, t=-3.10, P<0.05). Conclusion A trend of lateralization was found in patients with PSCI, rather than in the pathology.
