Abstract
Objective: To explore the clinical effect of Woven EndoBridge (WEB) in the treatment of wide-neck bifurcation aneurysms. Methods: The clinical and imaging data of 11 patients with intracranial wide-neck bifurcation aneurysms treated by WEB alone at Department of Neurosurgery of the Northern Theater General Hospital from September 2017 to May 2018, were retrospectively analyzed. The patients were 7 males and 4 females, aged (54±11) years (ranged from 31 to 66 years). The aneurysms of 5 patients were located in the anterior communicating artery, 3 in the top of the basilar artery, and 3 in the bifurcation of the middle cerebral artery. The intraoperative and postoperative conditions of the patients were recorded, and the degree of aneurysm embolization was evaluated by WEB embolization aneurysm occlusion scale (WOS). Results: The intraoperative WEB release of all the 11 patients was good, with 3 cases of WOS grade A, 1 of grade B and 7 of grade C, with no intraoperative acute complications occurring. The imaging follow-up was not carried out in 1 patient due to economic reason, and the clinical follow-up was good until 3 years after the operation; 10 patients were followed up by imaging for 6 months to 3 years, and no postoperative complications occurred in the target treatment area. Among the 2 patients with WOS grade A and 1 patient with grade B during operation, according to the postoperative follow-up, all were WOS grade A; among the 7 patients with WOS grade C during operation, 4 were still of grade C and 3 were of grade D according to the follow-up. Among the 3 patients with WOS grade D, 1 patient received secondary embolization due to poor recurrence morphology, unstable hemodynamics and high possibility of rupture of aneurysm, stent assisted coil embolization was adopted, with good immediate effect; the other 2 cases had recurrent aneurysms, but the aneurysms had good morphology and stable hemodynamics, therefore, clinical follow-up was continued and no secondary surgery was performed. No complications occurred in all these 11 patients. Conclusions: The operation of treating unruptured intracranial wide-neck bifurcation aneurysms with WEB device alone is simple, and there is no need for anticoagulation and antiplatelet treatment before and after the operation, the clinical effect is being good. WEB device provides a new treatment option for intracranial wide-neck bifurcation aneurysms.

Abstract
Objective: To investigate esophageal motility and reflux characteristics in gastroesophageal reflux disease (GERD) with and without extra-esophageal symptoms by high-resolution manometry and 24 h esophageal multichannel intraluminal impedance combined pH (MII-pH) monitoring. Methods: From February 2016 to June 2017, GERD patients with and without extra-esophageal symptoms were enrolled in this prospective controlled study. Esophageal HRM and 24 h MII-pH monitoring were performed. The differences in esophageal motility and reflux parameters were further analyzed between 30 GERD patients with extra-esophageal symptoms and 30 simple GERD patients. Results: The GERD symptom scores didn't show statistical difference between two groups. The GERD symptom scores didn't show statistical difference between two groups. The relaxation pressure of lower esophageal sphincter(LES), the integrated relaxation pressure, and the recovery time of upper esophageal sphincter(UES) of GERD patients with extra-esophageal symptoms were all lower than those of patients without extra-esophageal symptoms [(15±7) vs (21±11)mmHg, (8±3) vs (10±5)mmHg, (388±168) vs (492±170)ms, 1 mmHg=0.133 kPa], and the differences were statistically significant(all P<0.05). The main classification of esophageal motility type of GERD patients with extra-esophageal symptoms was mild esophageal motility disorders (27%, 8/30), and the occurrence of ineffective esophageal motivation was 20% (6/30), which were similar with simple GERD patients. The proximal reflux percentages of weak acid reflux and nonacid reflux, abnormal nonacid reflux in GERD patients with extra-esophageal symptoms were significantly higher than those in simple GERD patients [84.6% (73.2%, 100.0%) vs 75.0% (60.0%, 87.65%), P=0.048; 90.0% (45.8%, 100.0%) vs 0(0, 100.0%), P=0.017; 46.7% vs 3.3%, P=0.03]. Conclusions: The pathogenesis of GERD with extra-esophageal symptoms may be different from typical GERD. Increase of proximal esophageal reflux and abnormal nonacid reflux may all participate in the mechanisms of GERD with extra-esophageal symptoms.

Abstract
Objective: To compare the clinical data, esophageal motility and reflux characteristic in patients with non-erosive reflux disease (NERD) and reflux esophagitis (RE). Methods: A total of 167 patients of NERD were enrolled in the study[60 males, 107 females, mean age(44.1±13.4) years old], and 151 patients of RE were enrolled [74 males, 77 females, mean age(46.5±9.9) years old]. All patients were surveyed by questionnaires to investigate the clinical data. All patients accepted the esophageal highresolution manometry and 24 hours pH+ impedance monitoring to investigate the esophageal motility and reflux characteristic. Results: The proportion of female patients in group NERD was significantly higher than that in group RE(60/107 vs 74/77, P=0.049). The reflux symptom scores and the proportion of reflux in group NERD were significantly lower than those in group RE[(4.5±2.4) vs (5.6±2.1), 44.91% vs 64.24%, P<0.05). The Demeester score of group NERD was significantly lower than that of group RE[12.54(1.60, 10.80) vs 17.31(3.40, 16.64), P=0.044]. The proportion of Demeester scores positive patients in group NERD was significantly lower than that in group RE(15.1% vs 23.8%, P=0.018). The number of acid reflux in group NERD was significantly lower than that in group RE[17.49(3.00, 22.22) vs 21.69(4.00, 30.00), P=0.042]. Conclusions: There are more female patients in group NERD. The reflux symptoms of the group NERD are less serious than those of group RE.RE patients have more acid reflux events. There is no significant difference in the esophageal motility between the two groups.

Abstract
The literature reveals that stress in early life or adulthood can influence immune function. As most studies on this are from the laboratory, there is a need for replicated studies in wild animals. This study aims to examine the effects of density stress during the maternal period and adulthood on immune traits of root vole (Microtus oeconomus) individuals. Four replicated high- and low-density parental populations were established, from which we obtained offspring and assigned each into four enclosures, two for each of the two density treatments used in establishing parental populations. The F1 offspring fecal corticosterone metabolite response to acute immobilization stress, anti-keyhole limpet hemocyanin immunoglobulin G (anti-KLH IgG) level, phytohemagglutinin (PHA)-delayed hypersensitivity and hematology at the end of the first breeding season, and prevalence and intensity of coccidial infection throughout the two breeding seasons, were tested. Density-induced maternally stressed offspring had delayed responses to acute immobilization stress. Density-stressed offspring as adults had reduced anti-KLH IgG levels and PHA responses, and the effects further deteriorated in maternally stressed offspring, leading to higher coccidial infection in the first breeding season than in the second. No correlations were found between immune traits or coccidial infection and survival over winter. These findings indicated that the combined density stresses during the maternal period and adulthood exhibited negative synergistic effects on immune traits. The synergistic effects lead to higher coccidial infection; however, this consequently reduced the risk of subsequent infection. The increased coccidial infection mediated by the synergistic effects may have an adaptive value in the context of the environment.

Abstract
The hypothesis that maternal effects act as an adaptive bridge in translating maternal environments into offspring phenotypes, and thereby affecting population dynamics has not been studied in the well-controlled fields. In this study, the effects of maternal population density on offspring stress axis, reproduction and population dynamics were studied in root voles (Microtus oeconomus). Parental enclosures for breeding offspring were established by introducing six adults per sex into each of 4 (low density) and 30 adults per sex into each of another 4 (high density) enclosures. Live-trapping started 2 weeks after. Offspring captured at age of 20-30 days were removed to the laboratory, housed under laboratory conditions until puberty, and subsequently used to establish offspring populations in these same enclosures, after parental populations had been removed. [Correction added on 8 January 2015 after first online publication: '10-20 days' has been changed to '20-30 days.'] Offspring from each of the two parental sources were assigned into four enclosures with two for each of the two density treatments used in establishing parental populations (referred to as LL and LH for maternally unstressed offspring, assigned in low and high density, and HL and HH for maternally stressed offspring, assigned in low and high density). Faecal corticosterone metabolites (FCM) levels, offspring reproduction traits and population dynamics were tested following repeated live-trapping over two seasons. Differential fluctuations in population size were observed between maternally density-stressed and density-unstressed offspring. Populations in LL and LH groups changed significantly in responding to initial density and reached the similar levels at beginning of the second trapping season. Populations in HL and HH groups, however, were remained relatively steady, and in HL group, the low population size was sustained until end of experiment. Maternal density stress was associated with FCM elevations, reproduction suppression and body mass decrease at sexual maturity in offspring. The FCM elevations and reproduction suppression were independent of offspring population density and correlated with decreased offspring quality. These findings indicate that intrinsic state alterations induced by maternal stress impair offspring capacity in response to immediate environment, and these alterations are likely mediated by maternal stress system. The maladaptive reproduction suppression seen in HL group suggests intrinsic population density as one of ecological factors generating delayed density-dependent effects.

Abstract
The T-cell immunoglobulin and mucin domain (TIM) family is associated with autoimmune
diseases, but its expression level in the immune cells of systemic lupus
erythematosus (SLE) patients is not known. The aim of this study was to investigate
whether the expression of TIM-3 mRNA is associated with pathogenesis of SLE.
Quantitative real-time reverse transcription-polymerase chain reaction analysis
(qRT-PCR) was used to determine TIM-1, TIM-3, and TIM-4 mRNA expression in peripheral
blood mononuclear cells (PBMCs) from 132 patients with SLE and 62 healthy controls.
The PBMC surface protein expression of TIMs in PBMCs from 20 SLE patients and 15
healthy controls was assayed by flow cytometry. Only TIM-3 mRNA expression decreased
significantly in SLE patients compared with healthy controls (P<0.001). No
significant differences in TIM family protein expression were observed in leukocytes
from SLE patients and healthy controls (P>0.05). SLE patients with lupus nephritis
(LN) had a significantly lower expression of TIM-3 mRNA than those without LN
(P=0.001). There was no significant difference in the expression of TIM-3 mRNA within
different classes of LN (P>0.05). Correlation of TIM-3 mRNA expression with serum
IgA was highly significant (r=0.425, P=0.004), but was weakly correlated with total
serum protein (rs=0.283, P=0.049) and serum albumin (rs=0.297,
P=0.047). TIM-3 mRNA expression was weakly correlated with the Systemic Lupus
Erythematosus Disease Activity Index (SLEDAI; rs=-0.272, P=0.032). Our
results suggest that below-normal expression of TIM-3 mRNA in PBMC may be involved in
the pathogenesis of SLE.

Abstract
Curcumin, a natural anticancer agent, has been shown to inhibit cell growth in a number of tumor cell lines and animal models. We examined the inhibition of curcumin on cell viability and its induction of apoptosis using different gastric cancer cell lines (BGC-823, MKN-45 and SCG-7901). 3-(4,5-dimethyl-thiazol-2-yl)-2-5-diphenyltetrazolium-bromide (MTT) assay showed that curcumin inhibited cell growth in a dose- (1, 5, 10 and 30 μM) and time- (24, 48, 72 and 96 h) dependent manner; analysis of Annexin V binding showed that curcumin induced apoptosis at the dose of 10 and 30 μM when the cells were treated for 24 and 48 h. As cancers are caused by dysregulation of various proteins, we investigated target proteins associated with curcumin by two-dimensional gel electrophoresis (2-DE) and MALDI-TOF-TOF mass spectrometer. BGC-823 cells were treated with 30 μM curcumin for 24 h and total protein was extracted for the 2-DE. In the first dimension of the 2-DE, protein samples (800 μg) were applied to immobilized pH gradient (IPG) strips (24 cm, pH 3-10, NL) and the isoelectric focusing (IEF) was performed using a step-wise voltage ramp; the second dimension was performed using 12.5% SDS-PAGE gel at 1 W constant power per gel. In total, 75 proteins showed significant changes over 1.5-fold in curcumin-treated cells compared to control cells (Student's t-test, p<0.05). Among them, 33 proteins were upregulated and 42 proteins downregulated by curcumin as determined by spot densitometry. 52 proteins with significant mascot scores were identified and implicated in cancer development and progression. Their biological function included cell proliferation, cycle and apoptosis (20%), metabolism (16%), nucleic acid processing (15%), cytoskeleton organization and movement (11%), signal transduction (11%), protein folding, proteolysis and translation (20%), and immune response (2%). Furthermore, protein-protein interacting analysis demonstrated the interaction networks affected by curcumin in gastric cancer cells. These data provide some clues for explaining the anticancer mechanisms of curcumin and explore more potent molecular targets of the drug expected to be helpful for the development of new drugs.

Abstract
Studies have indicated that interleukin (IL)-10 has a pathogenic role in systemic lupus erythematosus (SLE); however, a protective effect of IL-10 in SLE was also observed. Because the exact mechanism of IL-10 signalling in the pathogenesis of SLE is unclear, this study sought to assess the expression and signalling of interleukin-10 receptor (IL-10R) in peripheral leucocytes from patients with SLE. We used flow cytometry to examine the expression of IL-10R1 on different peripheral leucocytes from 28 SLE patients, of whom 14 had lupus nephritis (LN) and 14 were healthy controls. We also examined the effects of IL-10 on phosphorylation of signal transducer and activator of transcription (STAT)-3 and STAT-1 in peripheral blood mononuclear cells (PBMCs) obtained from 13 SLE patients and seven healthy controls. Plasma cytokines were detected by flow cytometric bead array (CBA) techniques. Although IL-10R1 expression levels on each peripheral leucocyte subset from 28 SLE patients and 14 healthy controls were similar, the expression levels on CD4(+) T cells from LN patients were significantly lower than on CD4(+) T cells from controls and SLE patients without nephritis (P < 0·01). IL-10R1 expression levels on CD4(+) and CD8(+) T cells were correlated negatively with the SLE disease activity index (P < 0·01). Additionally, the phosphorylation of STAT-3 was delayed and reduced in PBMCs from LN patients and active SLE patients. Plasma IL-10 levels were significantly higher in LN patients than controls. IL-10R1 expression on CD4(+) T cells and signalling in PBMCs were down-regulated in LN patients, indicating that IL-10 and its receptor may have a special role in LN pathogenesis.

Abstract
Many cancers are chemotherapy-resistant. Chemotherapy combined with immunotherapy offers a potential avenue for the treatment of chemotherapy-resistant cancers. In this study, we investigated the apoptotic pathways induced by combined interferon-gamma/adriamycin treatment in Hep G2 cells. Our data showed that Hep G2 cells treated with combined interferon-gamma/adriamycin enhanced cell apoptosis in comparison with that of cells treated with adriamycin. Interferon-y increased TNFR-1, CSE1L/CAS (cellular apoptosis susceptibility protein), Bax, and Bad levels. Adriamycin increased p53 and Bax, but not TNFR- 1 and CAS levels. Interferon-y did not increase p53 accumulation; nevertheless it enhanced adriamycin-induced p53 accumulation. Overexpression of IRF-1 augmented the combined interferon-gamma/adriamycin-induced p53 accumulation. Interferon-gamma co-treatment increased the stability of p53 protein induced by adriamycin. Our data suggest that TNF-gamma may greatly enhance the combined interferon-gamma/chemotherapeutic drug-induced apoptosis of cancers. Our findings also indicate that CAS, TN-FR-1, p53, Bax, and Bad may be the targets for the interferon-y-based chemo-immunotherapy of the chemotherapy-resistant cancers.
