The changes of CD4~+,CD8~+ T lymphocyte percentage were determined by flow cytometry on admission and at 1 week,4 weeks after treatment.Another group of 20 cases was enrolled as control group.Results Compared with the control group,both the DEX treatment group and non-DEX treatment group showed a reduced CD4~+ lymphocyte count, an increased CD8~+ lymphocyte count(P

Background & Objective: Sleep quality in neuromyelitis optica spectrum disorders (NMOSD) were investigated in two recent studies. However, factors affecting sleep quality have not been studied in NMOSD. This study aimed to investigate the prevalence of sleep disorders in Chinese outpatient clinics with NMOSD and its clinical correlates. Methods: We administered Chinese validated self-questionnaires on HRQOL (MSQOL-54), sleep (PSQI), pain (SF-MPQ-2), anxiety (HARS) and depression (HDRS) to 42 patients followed up in our outpatient department. We assessed the relationships between sleep quality with pain, anxiety, depression, gender, age, disability, disease duration, NMO-antibody status and explored the determinants of poor sleep quality. Results: Sixty four percent of NMOSD patients were poor sleepers. Significant correlations were found between duration, disability, pain, anxiety, depression and sleep quality. Disability, depression and the domain of affective descriptors of pain were the three main predictors of poor sleep in NMOSD. Conclusion: This study reveals that poor sleep in NMOSD is common and it decreases physical function of quality of life. It is worthwhile considering exploring adjuvant strategies aimed at controlling pain associated affect, and treatment of depression may help to improve sleep quality in NMOSD.

Objective: To investigate the effect of phospholipase C epsilon 1 (PLCε1) gene silencing on apoptosis and invasion of esophageal carcinoma Eca109 cells and its possible mechanism. Methods: The recombinant vectors targeting short hairpin RNA (shRNA) of PLCε1 (pGenesil-1-PLCε1-shRNA, pGenesil-1-PLCε1-shRNA2 and pGenesil-1-PLCε1-shRNA3) were transfected into Eca109cells by cationic liposome method and to screen out the expression vector with best interference effect. The apoptosis rate and invasive ability of Eca109 cells 48 h after transfection were determined by flow cytometry (FCM) and Transwell chamber method, respectively. After PLCε1 gene silencing, the expression levels of factorassociated suicide (Fas), Fas ligand (FasL), CD44, matrix metalloproteinase-9 (MMP-9) and vascular endothelial growth factor (VEGF) mRNAs were detected by semi-quantitative reverse transcriptionpolymerase chain reaction (RT-PCR). Results: The pGenesil-1-PLCε1-shRNA2 had the best interference effect on PLCε1 gene. The apoptosis rate of Eca109 cells 48 h after transfection with PLCε1-shRNA2 was (30.27±5.13)%, which was significantly higher than that of the cells transfected with pGenesil-1-NC-shRNA (NC group) [(22.06±4.47)%, P < 0.05]. The number of Eca109 cells across the polycarbonate membrane of Transwell chamber in the NC group and PLCε1-shRNA2 group 48 h after transfection were 82.00±2.00 and 62.67±3.06, respectively. The number of Eca109 cells across the polycarbonate membrane in PLCε1-shRNA2 group was lower than that of the NC group (P < 0.05). The expression level of Fas mRNA in Eca109 cells of PLCε1-shRNA2 group was significantly up-regulated as compared with that of the NC group (P < 0.05), while the expression levels of FasL, MMP-9 and VEGF mRNAs in PLCε1 - shRNA2 group were significantly down-regulated (all P < 0.05). There was no significant difference in CD44 mRNA expression level between the NC group and PLCε1-shRNA2 group. Conclusion: Silencing PLCε1 gene might promote the apoptosis of Eca109 cells by up-regulating the expression of Fas and down-regulating the expression of FasL, and it can also suppress the invasive ability of Eca109 cells by down-regulating the expressions of MMP-9 and VEGF.

OBJECTIVETo explore the potential molecular mechanisms for Bushen Tiaojing Recipe (BTR) improving the endocrine function of ovarian granular cells by observing the effect of BTR containing serum on follicle stimulating hormone/cyclic adenosine monophosphate-protein kinase A (FSH/ cAMP-PKA) pathway in in vitro cultured human ovarian granular cells.

METHODSThe primary ovarian granular cells collected from in vitro fertilization-embryo transfer patients were cultured for 24 h. The human and rat serum containing different concentrations of BTR (low, medium, high dose), and their normal serums were co-incubated with ovarian granular cells for 48 h respectively, and then they were divided into the low, medium, high dose BTR groups and the control group. The levels of estradiol (E2), progesterone (P), and cyclic adenosine monophosphate (cAMP) in the culture medium were measured by radioimmunoassay. The protein expression of FSHR in ovarian granular cells was detected by Western Blot. The mRNA expression of follicle stimulating hormone receptor (FSHR) and P450 aromatase (P450arom) in ovarian granular cells were detected by Real-time PCR.

RESULTSIn human BTR containing serum groups: Compared with control group, the levels of E2 and cAMP in the culture medium were higher (both P < 0.05) in the medium and high dose BTR groups; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells increased (all P < 0.01), the mRNA expressions of P450arom in ovarian granular cells were higher (P < 0.05, P< 0.01) in the medium and high dose BTR groups. In rat BTR containing serum groups: Compared with the control group, the levels of E2 in the culture medium were higher (all P < 0.01), cAMP in the culture medium were higher (P < 0.05, P < 0.01) in the medium and high dose BTR group; the levels of P in the culture medium decreased in the medium dose BTR group (P < 0.01). The protein and mRNA expression of FSHR in ovarian granular cells were higher (all P < 0.01), the mRNA expression of P450arom in ovarian granular cells increased in the medium and high dose BTR groups (P < 0.05, P < 0.01).

CONCLUSIONBTR could possibly improve the endocrine function of ovarian granular cells by regulating main effector molecules FSHR, cAMP, P450arom, and E2 in FSH/cAMP-PKA pathway of ovarian granular cells.

D-myo-inositol 1,4,5-trisphosphate (IP(3)) plays an important role in signal transduction. It releases Ca(2+) from intracellular sites, which activates the Ca(2+)-dependent channels such as large-conductance Ca(2+)-activated potassium channels (BK channels). The present study was therefore designed to determine if the activity of BK channels in porcine coronary artery smooth muscle cells was increased by IP(3). Using the inside-out patch-clamp technique, the activity of single BK channels was recorded in porcine coronary artery smooth muscle cells. In excised inside-out membrane patches, IP(3) (10-50 micromol/L) enhanced the open probability (Po) of BK channels in a dose-dependent manner in the intracellular side of inside-out patches and its effect was almost completely abolished by washout. The open-state probability of the BK channels increased from a control level of 0.0402+/-0.0152 to 0.1365+/-0.0212 (20 micromol/L IP(3)) and 0.1865+/-0.0175 (30 micromol/L IP(3)). IP(3) decreased the mean close time markedly, but had no effect on the amplitude of BK channels. The activation of IP(3) on BK channels did not decline. The metabolite of IP(3) had no obvious effect on BK channels. This study provides evidence that IP(3) activates BK channels in porcine coronary artery smooth muscle cells in a dose-dependence manner.
