This paper aims to study the effect of Ziziphi Spinosae Semen extracts on chronic unpredictable mild stress(CUMS)-induced depression-like and insomnia behavior models of mice. The CUMS-induced depression-like and insomnia behavior model of mice was established by CUMS treatment for three weeks. The mice were randomly divided into control group, model group, positive drug diazepam group(2 mg·kg~(-1)), as well as low-dose group(1.95 g·kg~(-1)), medium-dose group(3.9 g·kg~(-1)), and high-dose group(7.8 g·kg~(-1)) of Ziziphi Spinosae Semen extracts, with 18 mice in each group. On the 15th day of modeling, the drug was administered intragastrically once a day for one week. Then, the pentobarbital sodium cooperative righting experiment, open field experiment, and elevated plus maze experiment were carried out, respectively. The contents of neurotransmitters 5-hydroxytryptamine(5-HT) and 5-hydroxyindoleacetic acid(5-HIAA) in serum and thalamus of mice, as well as the levels of corticotropin releasing hormone(CRH), adrenocorticotropic hormone(ACTH), and corticosterone(CORT) in serum, were determined by enzyme-linked immunosorbent assay(ELISA). The neuron damage in the hippocampus of mice was observed by hematoxylin-eosin(HE) staining and Nissl staining. Western blot was used to detect the expressions of tryptophan hydroxylase 2(TPH2), serotonin transporter(SERT), monoamine oxidase A(MAOA), five prime repressors under dual repression binding protein 1(Freud1), synaptic plasticity-related proteins [cellular gene FOS(C-FOS), postsynaptic density protein 95(PSD95), synapsin 1(SYN1), and activity-regulated cytoskeleton-associated gene(ARC)], blood-brain barrier(BBB) permeability-related proteins [zonula occludens 1(ZO-1), occludin, and claudin 1], inflammatory factors [NOD-, LRR-and pyrin domain-containing protein 3(NLRP3), apoptosis-associated speck-like protein(ASC), gasdermin D(GSDMD), caspase-3, and caspase-8], and antioxidant factors [nuclear factor erythroid 2-related factor 2(NRF2) and heme oxygenase 1(HO1)] in thalamic tissue of mice. The results indicated that compared with that in the model group, the sleep latency was significantly shortened, and the sleep duration was significantly prolonged in each dose group of Ziziphi Spinosae Semen extracts. The number of visits to the central area of the open field and the distance and time of visits were significantly increased in each dose group of Ziziphi Spinosae Semen extracts. In addition, the proportion of distance and time of entering the open arm area of the elevated plus maze was significantly increased in each dose group of Ziziphi Spinosae Semen extracts. The contents of 5-HT and 5-HIAA in serum and thalamus of mice increased to varying degrees in each dose group of Ziziphi Spinosae Semen extracts; the contents of CRH, ACTH, and CORT in serum of mice were significantly decreased. The protein expression of TPH2 was significantly increased. The protein expression of MAOA, SERT, and Freud1 was significantly decreased. Ziziphi Spinosae Semen extracts could also significantly reduce the protein expression of C-FOS but significantly increase the protein expression of PSD95, ARC, and SYN1. They could reduce the pathological damage of the hippocampus in mice and significantly increase the protein expression of ZO-1, occluding, and claudin 1. The protein expression of NLRP3, GSDMD, ASC, caspase-3, and caspase-8 in the thalamic tissue of mice was significantly decreased, and the protein expression of HO1 and NRF2 was significantly increased. In conclusion, Ziziphi Spinosae Semen extracts could effectively improve sleep disorders and depression-like behaviors in CUMS-induced model mice, which may be related to regulating the 5-HT anabolism process and hypothalamic-pituitary-adrenal(HPA) axis-related hormone levels, reducing pathological damage in the hippocampus, improving synaptic plasticity, repairing BBB integrity, and alleviating inflammatory response and oxidative stress damage.

Objective To analyze the genetic etiology of lateral ventriculomegaly fetal on the genome-wide level with chromosomal microarray analysis (CMA),and investigate the relationship between copy number variations (CNVs) and lateral ventriculomegaly and the application value of CMA in prenatal diagnosis of fetuses with lateral ventriculomegaly.Methods Seventy fetuses with lateral ventriculomegaly but normal or uncertain karyotype were selected and invasive prenatal diagnosis was performed in Xi Jing Hospital of the Fourth Military Medical University from Jan.2015 to Nov.2016.Microarray testing was performed using Affymetrix CytoScanTM 750k arrays and the results were analyzed according to biological information science database.The fetal development was regularly inspected,and follow up was conducted to find out the pregnancy outcome and fetal postnatal conditions.Results In 70 cases of lateral ventriculomegaly fetuses,there were 9 fetuses with pathogenic copy number variations (CNVs),3 fetuses with likely pathogenic CNVs and 1 fetus with likely pathogenic 1 oss of heterozygosity (LOH).During the 70 fetuses with lateral ventriculomegaly,2 pathogenic CNVs were detected in 6 fetuses with severe and non isolated lateral ventriculomegaly (33.3％).Pathogenic CNVs was not detected but 1 likely pathogenic CNV was detected in 3 fetuses with severe and isolated lateral ventriculomegaly (33.3％).Six pathogenic CNVs were detected in 31 mild and non isolated lateral ventriculomegaly (19.4％),and 2 likely pathogenic CNVs were also detected in these group (6.5％).One pathogenic CNV and 1 likely pathogenic CNV were detected in 30 fetuses with mild and isolated fetal lateral ventriculomegaly.Conclusions CMA can identify chromosome abnormality microdeletion/microduplication which was unrecognizable by conventional karyotyping analysis.The application of CMA may increase the detection rate of pathogenic CNVs in fetuses with lateral ventriculomegaly,and benefit evaluation of fetal prognosis in prenatal genetic counselling.

OBJECTIVETo understand the difference in clinical indicators of gout patients of different Chinese medical syndromes and its clinical significance.

METHODSForm November 2011 to December 2012, syndrome typed were 257 male gout in-/outpatients from Affiliated Hospital of Chuanbei Medical College. Another 50 healthy male subjects were recruited as the control. Their clinical and laboratory data were collected. All were excluded from infections and other inflammatory diseases.

RESULTSFour syndrome types existed in gout patients, i.e., intermingled phlegm-stasis blood syndrome (IPSBS), obstruction of dampness and heat syndrome (ODHS), Pi-deficiency induced dampness syndrome (PDIDS), qi-blood deficiency syndrome (QBDS). Of them, 53 acute phase gout patients suffered from IPSBS, 41 from ODHS, 25 from QBDS, and 17 from PDIDS; 41 non-acute phase gout patients suffered from QBDS, 40 from PDIDS, 24 from ODHS, and 16 from IPSBS. Statistical analysis of clinical data showed that, when compared with the normal control group, there was statistical difference in blood routines (WBC, GR, LY, MO) and blood biochemical indices (UA, Ur, Cr, ALT, AST, ALB, GLOB, TG, HDL-C, VLDL-C, apoA, apoB100) of gout patients of different syndromes (P < 0.05, P < 0.01). There was also statistical difference or correlation among different syndromes (P < 0.05).

CONCLUSIONSIn the acute phase gout patients, IPSBS and ODHS were dominated, while in the non-acute phase gout patients, QBDS and PDIDS were often seen. In patients of IPSBS and ODHS, inflammation and immune response were more obvious, indicating that better efficacy might be achieved by clearing heat and removing blood stasis associated anti-inflammatory and immune regulation therapies. In patients of QBDS and PDIDS, impaired renal functions were more significant, indicating that better efficacy might be achieved by invigorating Pi and tonifying Shen dominated treatment.
