ABSTRACT
Objective: To explore the difference of intestinal flora between the patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang and the healthy population. Method: The fecal samples of 9 patients with acute cerebral hemorrhage due to hyperactivity of liver-Yang from the first affiliated hospital of Guangzhou university of traditional Chinese medicine in 2018 were selected as observation group,and 6 stool samples from healthy subjects were selected as the control group.The total bacterial DNA was extracted from the two groups of samples,amplified according to the 16S rRNA V4 region,and paired-end sequencing was performed on the Illumina MiSeq platform.The sequencing results were analyzed by bioinformatics analysis software.The flora composition and structure of the samples from two groups were compared. Result:Venn analysis of operational taxonomic units(OTU) showed significant difference in OTU numbers between the observation group and control group.Partial least squares-discriminant analysis(PLS-DA) showed that there was a significant difference in the composition of intestinal flora between patients with acute cerebral hemorrhage and healthy subjects.On the analysis of species and abundance,at the classification level of phylum,compared with the control group,the ratio of relative abundance values of Firmicutes and Bacteroidetes(F/B) in the observation group was significantly increased,and the relative abundance of Verrucomicrobia was significantly decreased(PPrevotella,Bacteroides,Akkermansia,Blautia and Acidaminococcus(PPBacteroides and Prevotella(B/P) in the observation group was significantly higher than that of the control group;at the classification level of species,there were significant differences between the two groups in P. copri,A. muciniphila,B. ovatus,B. fragilis and Ruminococcus callidus(PPConclusion:Acute cerebral hemorrhage due to hyperactivity of liver-Yang is associated with structural disorder of intestinal flora,which is closely related to the decrease in relative abundance of P. copri and A. muciniphila.
ABSTRACT
Objective To examine serum levels of complement component 3(C3), complement component 4(C4), high sensitivity C reactive protein (hs-CRP), and uric acid (UA) in schizophrenia (SZ) patients and study their clinical significance. Methods One hundred forty-four SZ patients were recruited as SZ group. According to use of antipsychotics within four weeks, patients were divided into drug group (77 cases) and non-drug group (67 cases). One hundred forty-seven healthy subjects from health checkup center in the second XiangYa hospital during the same period were selected as control group. The concentrations of serum C3, C4, hs-CRP, and UA from SZ patients and healthy subjects were measured using immuno-scatter turbidmetry, latex-enhanced immunoturbidimetric assay, urea oxidase method, respectively. Results The serum levels of complement C3 and C4 were lower in SZ patients than in control group [(0.99±0.17) g/L vs. (1.03±0.17) g/L、(0.21±0.05) g/L vs. (0.23±0.05) g/L], and the serum levels of UA in serum of was higher in SZ patients than in control group [(351.61±95.90) μmol/L vs. (300.28±39.57) ?mol/L]. The differences had statistical significance (P<0.05, P<0.05, and P<0.001, respectively). The serum levels of C3, C4, hs-CRP, and UA were higher in drug group than in no-drug group [(1.04±0.19) g/L vs. (0.95±0.15) g/L、(0.22±0.06) g/L vs. (0.20±0.05) g/L、1.08(0.33, 5.04) mg/L vs. 0.47(0.28, 1.29) mg/L、(374.54±108.33)μmol/L vs. (331.61±79.03)μmol/L], and the differences had statistical significance (P<0.01).The concentrations of serum hs-CRP and UA were higher in drug group than in control group[1.08(0.33, 5.04) mg/L vs. 0.61(0.33, 1.26) mg/L、(374.54±108.33) μmol/L vs. (300.28±39.57) μmol/L], and differences had statistical significance (P<0.001). Conclusion The serum levels of C3, C4, hs-CRP, and UA in SZ Patients will be of guiding significance for clinical diagnosis of SZ and efficacy evaluation of antipsychotic drugs.
