ObjectiveTo investigate the diagnoses of somatic diseases of inpatients with psychosis and hospitalized more then 2 years.MethodsThe material of all 350 inpatients were investigated and analyzed.ResultsThe first three psychiatric diagnoses were schizophrenia (61.32%), Alzheimer's disease (15.26%), mood disorder (4.74%). The first three diagnoses of accompanying somatic diseases were heart disease (8.68%), diabetes mellitus (8.42%), and hypertension (4.47%).ConclusionWith the changes of social environment, the disease pedigree of inpatients with psychosis changes, senile patients become more and more, and the incidence of concurrent somatic diseases gradually increases.

To investigate the therapeutic effect of artesunate on mouse cytomegalovirus pneumonia, the BALB/c-nu mice were infected with murine cytomegalovirus-green fluorescent protein (MCMV-GFP) by nose dropping method. The experimental protocol was approved by the Medical Laboratory Animal Ethics Committee of Guangzhou Medical University. The BALB/c-nu mice were randomly divided into five groups: control group, MCMV pneumonia group, and artesunate (60, 120, and 240 mg·kg^-1) groups. The survival rate, weights, and virus loads in lungs among the groups were observed. The degree of histopathologic changes in lungs was assessed directly by hematoxylin-eosin (HE) assay. MCMV-GFP expression was assessed by immunofluorescence. In addition, reverse transcription polymerase chain reaction (RT-PCR) analysis was performed to investigate the content of major immediate early 1 (Mie1) mRNA, and enzyme-linked immunosorbent assay (ELISA) was used to detect the changes of inflammatory factors, interleukin 10 (IL-10), IL-6, and tumor necrosis factor-α (TNF-α). Western blot analysis was used to detect the expression of the changes of nuclear factor-kappa B (NF-κB) signaling pathways in total proteins. Compared with MCMV group, artesunate (120 mg·kg^-1) significantly increased body weights of MCMV-infected nude mice over 30 days, and decreased the viral titer in lung homogenate, lung inflammation, and histological severity. Moreover, the administration of artesunate (120 mg·kg^-1) could downregulate the expression of phospho-NF-κB (p-NF-κB) p65 in the lungs of mice. The present study suggested that artesunate can protect the immunocompromised mice from MCMV-induced interstitial pneumonia via downregulating NF-κB signaling pathway, thus attenuating inflammation in the lungs.

Background Cellular autophagy is a non-apoptosis death form of tumor tissue.Research determined that arsenie trioxide (As2O3) leads to apoptosis of tumor cells.But whether As2O3 induce autophagy of SO-Rb50 cells or not is unclear.Objective This study was to assess the effects of As2O3 on autophagy of SO-Rb50 cells.Methods As2O3 with the concentration of 0,0.5,1.0,2.0,4.0 μmol/L was used to treat the SO-Rb50 cell line for 48 hours,and the growth and proliferation of SO-Rb50 cells were detected using MTT assay (A570).pGFP-LC3,a marker of autophagy,was constructed to transfer SO-Rb50 cells,and the cells were then divided into RPMI-1640 culture group (untreated group),As2O3 + RPMI-1640 culture group (As2O3 treated group) and rapamycin culture group (positive control group).Autophagy of SO-Rb50 cells was examined by laser confocal microscope and monodansylcadaverine (MDC) influorescence staining,respectively,48 hours following cell culture.Ultrastructural features of autophagy were examined with transmission electron microscope (TEM).The percentage of autophagy positive cells in different concentrations of As2O3 treated groups was calculated with flow cytometer.Results The A570 values of SO-Rb50 cells were 2.194±0.066,1.841 ±0.213,1.035±0.046,0.374±0.042 and 0.167±0.019 in 0,0.5,1.0,2.0,4.0 μmol/L As2O3 treated groups,with a significant difference among these 5 groups(F=547.636,P＜0.05),and those of 0.5,1.0,2.0,4.0 μmol/L As2O3 treated groups were significantly reduced in comparison with untreated group (P =0.000).The positive granular spots for GFP-LC3 chimeric protein were seen to aggregate in autophagic vacuoles in the As2O3 treated group and positive control group,but diffuse cytoplasmic signal for GFP-LC3 was found in the untreated group.Normal ultrastructure of SO-Rb50 cells was exhibited in the untreated group,and many double-membrane-like bound vesicles and autlysosomes were documented in the As2O3 treated group and positive control group under the TEM.A lots of MDC fluorescence granule were found in the As2O3 treated group and positive control group rather than the untreated group.Flow cytometry showed that the percentages of SO-Rb50 cells were 0,15.6％,42.7％,57.9％,79.5％ and 89.0％ in the 0,0.5,1.0,2.0,4.0 μmol/L As2O3 groups and positive control group,respectively,showing a As2O3 concentration-dependent increase.Conclusions As2O3 can induce the autophagy of SO-Rb50 cells and inhibit the proliferation of SO-Rb50 cells.Autophagic response of SO-Rb50 cells appears prior to the nuclear change after exposed to As2O3.The degree of autophagy of SO-Rb50 cells is associated with As2O3 dose.

In this paper, three spoilage organisms were separated from five transmutative soy milks, and all the three spoilage bacteria could survive condition of both 1?105Pa,30min and 300mg/kg Nisin. Morpha character, physiological and biochemical characteristics, and a phylogenetic analysis based on 16S rDNA gene sequences reveal that these three strains are Bacillus licheniformis, Bacillus pumilus and Brevibacillus borstelensis respectively. GenBank accessions for these three strains are EF439666-EF439668。

At the present time, training student to have innovative and applied ability has become the object of higher education in China. In this paper, it was proposed that teacher was obligated to create certain atmospheres in classroom to achieve this goal, including friendliness, harmoniousness, encouragement, happiness, discussion, exploration, etc. At the same time, student-centered study should be encouraged. Through these measures, the spirit of innovation will be inspired, the applied ability will be trained, the capability of self-study will be enhanced.

Chemical constituents of 95% ethanol extract of the dried persistent calyx of Physalis pubescens were investigated. By chromatography on a silica gel column and reverse-phase preparative HPLC, 10 compounds were isolated from the dichloromethane fraction. Based on the MS and 1D/2D NMR data, these compounds were identified as 5-O-(E-feruloyl) blumenol (1), isovanillin (2), (E) -ethyl 3-(4-hydroxyphenyl) acrylate (3), 4-hydroxybenzaldehyde(4), 4-methylphenol (5), (E) -methyl cinnamate (6), 7,3',4' trimethoxyquercetin (7), 5,3', 5'-trihydroxy-3,7,4'-trimethoxyflavone(8), danielone (9), and 5,5'-diisobutoxy-2,2'-bifuran (10).
