Abstract
ETHNOPHARMACOLOGICAL RELEVANCE It has been found that pilose antler peptide has an antidepressant effect on depression. However, the exact molecular mechanism of its antidepressant effect is still unclear. AIM OF THE STUDY The study sought to determine the impact of monomeric pilose antler peptide (PAP; sequence LVLVEAELRE) on depression as well as investigate potential molecular mechanisms. MATERIALS AND METHODS Chronic unexpected mild stress (CUMS) was used to establish the model, and the effect of PAP on CUMS mice was detected by the behavioral test. The influence of PAP on neuronal cells and dendritic spine density was observed by immunofluorescence and Golgi staining. FGFR3 and the CaMKII-associated pathway were identified using quantitative real-time polymerase chain reaction, and Western blot analysis was utilized to measure their proteins and gene expression levels. Molecular docking and microscale thermophoresis were applied to detect the binding of PAP and FGFR3. Finally, the effect of FGFR3's overexpression on PAP treatment of depression was detected. RESULTS PAP alleviated the changes in depressive behavior induced by CUMS, promoted the growth of nerve cells, and the density of dendritic spines was increased to its original state. PAP therapy successfully downregulated the expression of FGFR3 and ERK1/2 while upregulating the expression of CREB, BDNF, and CaMKII. CONCLUSION Based on the current research, PAP has a therapeutic effect on depression brought on by CUMS by inhibiting FGFR3 expression and enhancing synaptic plasticity.

Abstract
Ten-eleven translocation protein 1 (Tet1) is associated with the regulation of depression-like behaviour in mice. However, the mechanism by which Tet1 affects neurogenesis in mice to regulate depression-like behaviours remains unclear. In this study, the chronic social defeat stress (CSDS) paradigm was constructed by overexpressing Tet1 protein in the mouse hippocampus, and 5-ethynyl-2'-deoxyuridine (EdU, 50 mg/kg) was injected on the seventh day to explore the mechanism of the regulation of the Tet1/Delta-like protein 3 (DLL3)/Notch1 protein pathway in mice hippocampal neurogenesis and its influence on depression-like behaviour. Following CSDS, the expression level of Tet1 decreased significantly. Moreover, due to the downregulation of Tet1 protein, the maintenance of the DNA methylation and demethylation balance was affected, resulting in a significant increase in the methylation levels of Notch1 and DLL3 and a significant decrease in the protein expression levels of DLL3, Notch1, and brain-derived neurotrophic factor (BDNF). At the same time, the proliferation and differentiation of neurones were affected, which was related to a significant decrease in the number of EdU+, doublecortin (DCX)+, and Ki67+ cells in the hippocampus of the CSDS model mice. When the Tet1 protein was overexpressed in the mouse hippocampus, DLL3 and Notch1 protein expression levels were upregulated, promoting hippocampal neurogenesis and alleviating depression-like behaviour in mice. These findings suggest that regulation of the hippocampal Tet1/DLL3/Notch1 protein pathway to influence neurogenesis may be a therapeutic strategy for depression.

Abstract
Objective: To investigate the concern about pollen broadcasting in Chinese population from multiple dimensions and to understand the information about allergic rhinitis (AR) in China by analyzing related factors. Methods: From March 1 to September 30, 2022, a large-scale multi-center cross-sectional survey was conducted based on the Questionnaire Star platform in 21 Chinese hospitals. A total of 7 056 subjects from 7 regions in China: Northeast, North, East, Central, South, Southwest, and Northwest China were included. Basic characteristics (including social demographic characteristics and disease characteristics of AR patients), concern about pollen broadcasting, the willingness of pollen-induced AR (PiAR) patients to receive pollen broadcasting, and the treatment satisfaction rate of AR patients were collected. The chi-square test, multivariate linear regression model, and Logistic regression analysis were used to analyze the concern about pollen broadcasting in the Chinese population and related factors from multiple dimensions. Results: Among 7 056 subjects, 23.02% were concerned about pollen broadcasting. Among 3 176 self-reported AR and 1 019 PiAR patients, 25.60% and 39.16% were concerned about pollen broadcasting, respectively, which was higher than that of non-AR or non-PiAR subjects (χ2 value was 21.74 and 175.11, respectively, both P<0.001). Among AR patients, the proportion of spring and autumn allergen-positive patients concerned about pollen broadcasting was higher than that in perennial allergen-positive patients (χ2 value was 20.90 and 19.51, respectively, both P<0.001). The proportion of AR patients with asthma, sinusitis, allergic conjunctivitis, and cardiovascular and cerebrovascular diseases was higher than those without complications (χ2 value was 50.83, 21.97, 56.78, 7.62, respectively, all P<0.05). The proportion of AR patients in North China who could find pollen broadcasting locally was 31.01%, significantly higher than those in other regions (all P<0.05). Multivariate linear regression model analysis showed that among PiAR patients, those with higher per capita household income and higher AR disease cognition levels had been concerned about pollen broadcasting in the past, and those complicated with allergic conjunctivitis had stronger intention to receive pollen broadcasting (B value was 0.24, 0.13, 0.66, 0.47, respectively, all P<0.05). The higher the disease cognition level of PiAR patients, the stronger their willingness to actively participate in treatment (R2=0.72, P<0.001). Only 18.89% of AR patients felt satisfied with the treatment effect. Logistic regression analysis showed that in AR patients, the treatment satisfaction rate was significantly higher among those concerned about pollen broadcasting compared to those who were not (OR=1.83, P<0.001). Conclusions: Currently, the dissemination of pollen broadcasting in China is hindered by various factors such as disease cognition level. The treatment satisfaction among AR patients remains unsatisfactory.

Abstract
BACKGROUND To investigate the value of fluid-attenuated inversion recovery vascular hyperintensity (FVH) within asymmetrical prominent veins sign (APVS) on susceptibility-weighted imaging predicting collateral circulation and prognosis in patients with acute anterior circulation ischemic stroke. METHOD Patients with severe stenosis or occlusion of ICA or MCA M1, who underwent MRI within 72 h from stroke onset were reviewed. The Alberta Stroke Program Early CT Score was used to evaluate the volume of infarction on DWI, the degree of FVH and APVS. Spearman correlation analysis was used to evaluate the correlation between FVH and APVS. All patients were divided into the good prognosis group and the poor prognosis group according to the score of the modified ranking scale (mRS) 90 days after the stroke. Logistic regression analysis was used to explore the relationship between FVH and APVS and functional prognosis, while receiver operating characteristic (ROC) curves were plotted to assess the value of FVH and APVS in predicting prognosis. RESULTS Spearman correlation analysis revealed moderate positive correlations between FVH and APVS (r = 0.586, P < 0.001). The poor prognosis group had a higher rate of a history of atrial fibrillation, a larger cerebral infarction volume, a higher NIHSS score at admission, and a higher FVH and APVS score compared with the good prognosis group (all P < 0.05). A further logistic regression indicated that the NIHSS score, cerebral infarction volume, FVH and APVS were independent risk factors for a poor functional prognosis. In terms of FVH, APVS, alone and their combination for the diagnosis of poor prognosis, the sensitivity, specificity, area under the ROC curve (AUC), and 95% confidence interval (CI) were 86.8%, 83.3%, 0.899 (95% CI 0.830-0.968); 60.5%, 93.7%, 0.818 (95% CI 0.723-0.912); 86.8%, 89.6%, 0.921 (95% CI 0.860-0.981), respectively. CONCLUSION The presence of FVH and APVS can provide a comprehensive assessment of collateral circulation from the perspective of veins and arteries, and the correlation between the two is positively correlated. Both of them were independent risk factors for poor prognosis, their combination is complementary and can improve the predictive value.

Abstract
Background and purpose The dynamic alterations in spontaneous neural activity of the brain during the acute phase of post-stroke aphasia (PSA) remain unclear. Therefore, in this study, dynamic amplitude of low-frequency fluctuation (dALFF) was applied to explore abnormal temporal variability in local functional activity of the brain during acute PSA. Materials and methods Resting-state functional magnetic resonance imaging (rs-fMRI) data from 26 patients with PSA and 25 healthy controls (HCs) were acquired. The sliding window method was used to assess dALFF, with the k-means clustering method used to identify dALFF states. The two-sample t-test was applied to compare differences in dALFF variability and state metrics between the PSA and HC groups. Results (1) In the PSA group, greater variance of dALFF in the cerebellar network (CBN) and left fronto-temporo-parietal network (FTPN) was observed. (2) Three dALFF states were identified among all subjects. States 1 and 2 were identified in the PSA patients, and the two dALFF states shared a similar proportion. Moreover, the number of transitions between the two dALFF states was higher in the patients compared with that in HCs. Conclusion The results of this study provide valuable insights into brain dysfunction that occurs during the acute phase (6.00 ± 3.52 days) of PSA. The observed increase in variability of local functional activities in CBN and left FTPN may be related to the spontaneous functional recovery of language during acute PSA, and it also suggests that cerebellum plays an important role in language.

Abstract
OBJECTIVE This study aimed to describe the current situation and explore overwork predictors among ICU nurses in China. BACKGROUND Overwork is a comprehensive condition of labor where employees work for extended periods with high intensity and high pressure, which can negatively affect their health. Limited literature exists regarding the prevalence, characteristics, professional identity, and environment of overwork among ICU nurses. METHODS A cross-sectional design study was conducted. The Professional Identification Scale for Nurses, the Practice Environment Scale of the Nursing Work Index, and the Overwork Related Fatigue Scale (ORFS) were used. To explore relationships between variables, univariate analysis or bivariate correlations were used. Multiple regression was used to identify predictors of overwork. RESULTS Almost 85% of nurses were categorized as overworked, of which, 30% were moderately to severely overworked. Gender, form of employment, stress related to ICU nursing technology and equipment updates, nurses' professional identity, and nurse working environment accounted for 36.6% in the ORFS. CONCLUSIONS Overwork is common among ICU nurses. Nurse managers need to develop and implement strategies to better support nurses to prevent overwork.

Abstract
OBJECTIVES This study aims to explore the role of lncRNA TMPO-AS1 in ischemic stroke and corresponding mechanism. METHODS Adult male C57BL/6 J mice were subjected to a middle cerebral artery occlusion (MCAO) model of ischemic stroke, then TMPO-AS1 shRNA lentivirus were injected into ipsilateral striatum of mice. The neurological score and cerebral infarction volume were evaluatedHypoxia/glucose deprivation/reoxygenation (OGD/R)-induced BV2 cells were transfected with TMPO-AS1 shRNA (sh-TMPO-AS1) or together with pcDNA-INPP5D, as well as transfected with sh-PU.1 or together with pcDNA-INPP5D, then TMPO-AS1 level, the expression of PU.1 and INPP5D proteins, the secretion of inflammatory factors (TNF-α, IL-6 and IL-1β), the levels of iNOS, CD68,Arg1 and CD206 mRNA were detected. RIP and PNA-pull down assays were used to detect the binding of TMPO-AS1 and PU.1, luciferase reporter gene and chromatin immunoprecipitation (ChIP) assays were used to detect the binding activity of PU.1 and INPP5D. RESULTS TMPO-AS1 level was increased in peripheral blood of ischemic stroke patients , brain tissues of MCAO/R model mice and OGD/R-induced BV2 cells. TMPO-AS1 interference inhibited the inflammation of OGD/R-induced BV2 cells. TMPO-AS1 also enhanced the nuclear accumulation of PU.1 by binding to the transcription factor PU.1, and promoted the transcriptional activation of INPP5D. The anti-inflammatory effects of TMPO-AS1 interference were reversed by INPP5D overexpression. In addition, TMPO-AS1 interference improved the infarct volume of MCAO mice, and improved sensorimotor and cognitive functions. CONCLUSION INPP5D underexpression mediated by TMPO-AS1-PU.1 complex alleviated neuroinflammation after ischemic stroke.

Abstract
Vaginal microbiome is mutually beneficial to the host and has a significant impact on health and disease. Candida species, including Candida albicans, are part of the mucosal flora of most healthy women. Under suitable conditions, they can live in the vulvovaginal mucosa, resulting in symptomatic vulvovaginal candidiasis (VVC). Based on the analysis of 16S ribosomal RNA gene sequences, great progress has been made in exploring the composition and structure of vaginal bacterial community. Moreover, researchers have conducted several studies on whether vaginal microbiome will change during VVC infection. In addition, it has been reported that vaginal colonization of probiotics in vaginal microorganisms, especially Lactobacillus, can effectively reduce the risk of VVC and treat VVC. This review aims to summarize the changes of vaginal microflora during VVC infection, and further point out the possibility of using lactic acid bacteria as probiotics to treat VVC, so as to reduce the adverse consequences of VVC infection and reduce the expensive treatment cost.

Abstract
BackgroundThe prominent veins sign (PVS) on susceptibility-weighted imaging (SWI) has been suggested to be related to the prognosis of patients with acute ischemic stroke (AIS). This meta-analysis aims to clarify the association between PVS and the prognosis of patients with AIS.MethodsThis meta-analysis was registered in PROSPERO (no. CRD42022343795). We performed systematic research in PubMed, Web of Science, EMBASE, and Cochrane Library databases for studies investigating the prognostic value of PVS. Based on the enrolled studies, patients were divided into two groups as follows: those with PVS cohort and those without PVS cohort. Outcomes were unfavorable functional outcome, early neurological deterioration (END), and hemorrhagic transformation (HT). The random-effects models were used for the meta-analytical pooled. Heterogeneity was estimated using Cochran's Q-test and I2 value. Subgroup and sensitivity analyses were also performed to explore the potential sources of heterogeneity. Publication bias was assessed with funnel plots and using Begger's and Egger's tests.ResultsA total of 19 studies with 1,867 patients were included. PVS was correlated with an unfavorable functional outcome in patients with AIS (risk ratio [RR] 1.61, 95% CI 1.28–2.02), especially in those receiving recanalization therapy (RR 2.00, 95% CI 1.52–2.63), but not in those treated conservatively (RR 1.33, 95% CI 0.87–2.04). Moreover, PVS was related to END (RR 2.77, 95% CI 2.21–3.46), while without an increased risk of HT (RR 0.97, 95% CI 0.64–1.47).ConclusionPVS was associated with an unfavorable prognosis of patients with AIS and increased the risk of END, while not correlated with an increased risk of HT. PVS might be useful for predicting functional outcomes of patients with AIS as a novel imaging maker.Systematic review registrationhttps://www.crd.york.ac.uk/PROSPERO/, identifier: CRD42022343795.

Abstract
PURPOSE The role of autophagy in prostate cancer metastasis remains controversial, and the effects of the autophagy-related gene ATG5 on prostate cancer metastasis are poorly understood. This study aims to explore the effects of ATG5 on prostate cancer metastasis and its molecular mechanism. METHODS The metastatic characteristics of LNCaP and DU145 cells were assessed by NOD/SCID mouse experiments, western blot, transwell assay, and wound-healing assay. Double membrane autophagic vesicle observation and the adenovirus-expressing mCherry-GFP-LC3B fusion protein were used to assess the autophagic characteristics of LNCaP and DU145 cells. The role of p62 in the accumulation of TWIST1 was confirmed by western blot under different conditions. The lentivirus particles of shATG5, NOD/SCID mice experiments, western blot, transwell assay, and wound-healing assay were used to confirm the role of ATG5 in TWIST1 accumulation and prostate cancer cell metastasis. RESULTS We identified a stabilizing effect of p62 on TWIST1 in the autophagic regulation of EMT and prostate cancer metastasis. The loss of ATG5 in DU145 cells resulted in autophagy deficiency and p62 accumulation, which stabilized TWIST1 and increased the TWIST1 level in prostate cancer cells, and eventually promoted EMT and metastasis. In comparison, LNCaP cells with regular ATG5 expression and autophagy status retained remarkable epithelial cell characteristics and had limited metastatic characteristics. Similar results were also found in wild-type LNCaP cells and LNCaP cells with stable ATG5 interference. CONCLUSIONS Our research revealed ATG5-mediated autophagy as a key mechanism that controls the metastasis of prostate cancer by regulating p62 abundance and TWIST1 stabilization.

Abstract
Microglia are the static resident cells possessing the phagocytic properties in the central nervous system (CNS). In many relevant studies, the immortalized murine microglial cell line BV2 has been used as a tool in primary microglia (PM) relevant studies. Microglia participate in neuroinflammation by converting into M1- and M2-like phenotypes. In this study, we established M1- and M2-like phenotype response models by exposing PM and BV2 cells to lipopolysaccharides (LPS) and interlukin-4 (IL-4), respectively, and discovered the proteomic differences between the two types of microglia. It turned out that the BV2 cells responses to LPS and IL-4 were narrower and weaker than that of PM. In addition, irradiation, which has been shown to activate microglia and induces neuroinflammation, was also used as a treatment in this study. The results showed that BV2 cells have stronger capacity of DNA damage repair. Besides, irradiation had a negative effect on the regulation of KEGG pathways such as proteasome, ribosome, oxidative phosphorylation and TCA cycle in both cells. Furthermore, the KEGG pathways including cell cycle and DNA replication (significantly down-regulated), and antigen processing and presentation and FC γ R mediated phagocytosis (significantly up-regulated) were only found in irradiated PM. These data demonstrate that PM is more fragile to irradiation. Results in this study indicate that BV2 cells only partially model PM and thus using BV2 in microglia related studies should be carefully considered.

Abstract
Immunotherapy against cancer, through immune checkpoint inhibitors targeting the programmed cell death-1/programmed cell death-ligand 1 axis, is particularly successful in tumors by relieving the immune escape. However, interindividual responses to immunotherapy are often heterogeneous. Therefore, it is essential to screen out predictive tumor biomarkers. In this study, we analyzed the commensal microbiota in stool samples and paired sputum samples from 75 metastatic non-small-cell lung cancer (NSCLC) patients at baseline and during treatment with immune checkpoint inhibitors. Results showed distinct microbes' signatures between the gut microbiota and paired respiratory microbiota. The alpha diversity between the gut and respiratory microbiota was uncorrelated, and only the gut microbiota alpha diversity was associated with anti-programmed cell death-1 response. Higher gut microbiota alpha diversity indicated better response and more prolonged progression-free survival. Comparison of bacterial communities between responders and nonresponders showed some favorable/unfavorable microbes enriched in responders/nonresponders, indicating that commensal microbiota had potential predictive value for the response to immune checkpoint inhibitors. Generally, some rare low abundance gut microbes and high abundance respiratory microbes lead to discrepancies in microbial composition between responders and nonresponders. A significant positive correlation was observed between the abundance of Streptococcus and CD8+ T cells. These results highlighted the intimate relationship between commensal microbiota and the response to immunotherapy in NSCLC patients. Gut microbiota and respiratory microbiota are promising biomarkers to screen suitable candidates who are likely to benefit from immune checkpoint inhibitor-based immunotherapy.

Abstract
Purpose: To investigate the hepatoprotective role of ganoderic acid A (GAA) on liver cancer induced by diethylnitrosamine (DEN) via Nrf-2/HO-1/NF-κB signal pathway in mice.
Methods: Sixty male C57BL/6J mice were randomly divided into 4 groups: (1) control group, (2) DEN (25 mg/kg) group, (3) GAA (20 mg/kg) + DEN group, (4) GAA (40 mg/kg) + DEN group. The protective effect of GAA on liver was evaluated by determining malondialdehyde (MDA), superoxide dismutase (SOD), inflammatory cytokines including interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and the expression of heme oxygenase-1 (HO-1), nuclear factor erythroid- 2-related factor-2 (Nrf-2), IκBα, p-IκBα, p65, p-p65, glyceraldehyde-3-phosphate dehydrogenase (GAPDH) in serum.
Results: The results demonstrate that GAA treatment significantly suppressed the generation of MDA, proinflammatory cytokines, and restored the activity of SOD in the serum of DEN-induced liver cancer in mice. Western blots analysis revealed that GAA significantly restored Nrf-2/HO-1/NF-κB signal pathwayrelated protein levels in DEN-induced mice liver cancer model.
Conclusion: This research reveals the anticancer activity of GAA in liver tissue, and suggests that GAA counters DEN-induced liver cancer through Nrf-2/HO-1/NF-κB signal pathway.
Keywords: Ganoderic acid A, Nrf-2/HO-1/NF-κB pathway, Liver cancer, MDA, GAPDH, SOD

Abstract
Objective: To evaluate the 4-year clinical outcomes of patients following Firesorb bioresorbable scaffold (BRS) implantation. Methods: The study reported the 4-year follow-up results of the FUTURE I study. FUTURE I was a prospective, single-center, open-label, first-in-man study which evaluated the feasibility, preliminary safety, and efficacy of Firesorb stent in the treatment of coronary artery stenosis. A total of 45 patients with single de novo lesions in native coronary arteries ,who hospitalized in Fuwai Hospital from January to March 2016 were enrolled. After successfully stent implantation these patients were randomized in a 2∶1 ratio into cohort 1 (n=30) or cohort 2 (n=15). The patients in cohort 1 underwent angiographic, IVUS or OCT examination at 6 months and 2 years; and cohort 2 underwent angiographic, IVUS or OCT at 1 and 3 years. All patients underwent clinical follow-up at 1, 6 months and 1 year and annually thereafter up to 5 years. The primary endpoint was target lesion failure (TLF, including cardiac death, target vessel myocardial infarction, and ischemia-driven target lesion revascularization). Secondary endpoints included patient-oriented composite endpoint (PoCE, defined as composite of all death, all miocardial infarction, or any revascularization). Results: A total of 45 patients were enrolled and implanted with Firesorb BRS, including 35 males (77.8%), and the age was (54.4±9.3) years. At 4 years, 10 patients in cohort 1 were reexamined by coronary angiography and OCT examination. Among them, 2 patients' stents were completely degraded and absorbed. Compared with the OCT images of the other 8 patients in cohort 2 at 3 years, the degree of stent degradation was increased, and no stent adherence was found. The 4-year clinical follow-up rate was 100%. In 4-year clinical following up, 2 patients suffered PoCE (4.4%): 1 patient underwent non-target vessel revascularization the day after index procedure and target vessel revascularization (Non-target lesion revascularization) at 2-year imaging follow-up; the other patient underwent target lesion revascularization during imaging follow-up at 4 years but not due to ischemic driven. There was no scaffold thrombosis or TLF events through 4 years. Conclusions: Four years after the implantation, complete degradation and absorption of the Firsorb stent are evidenced in some patients. Firesorb stent is feasible and effective in the treatment of patients with non-complex coronary lesions.

Abstract
Lung cancer is the most common malignant tumor and is the leading cause of cancer-related deaths worldwide. Extraction of bioactive substances from herbs is considered as an alternative method to traditional treatment. 6-Gingerol is a naturally occurring phenol found in ginger that can be used to treat tumors and suppress inflammation. To determine whether 6-Gingerol can be used as a therapeutic agent for tumors. In this study, tumor-bearing mice were used as an animal model and A549 as a cell model. Western blot was used to detect the expression of autophagy related proteins ubiquitin-specific peptidase 14 (USP14), Beclin1, microtubule-associated protein light chain 3 (LC3) and ferroptosis related proteins nuclear receptor coactivator 4 (NCOA4), ferritin heavy chain 1 (FTH1), transferrin receptor 1 (TfR1), glutathione peroxidase 4 (GPX4), activating transcription factor4 (ATF4) in vivo and in vitro. MTT and EdU were used to detect the viability of A549 cells. H&E and immunofluorescence were used to localize and detect the expression of proteins. The detection of reactive oxygen species was performed using fluorescence probes. It was found that the administration of 6-Gingerol decreased the expression of USP14, greatly increased the number of autophagosomes, reactive oxygen species (ROS) and iron concentration, decreased the survival and proliferation rate of A549 cells, and significantly decreased tumor volume and weight. The results indicate that 6-Gingerol inhibits lung cancer cell growth via suppression of USP14 expression and its downstream regulation of autophagy-dependent ferroptosis, revealing the function and efficacy of 6-Gingerol as a therapeutic compound in A549 and its possible mechanism of action.

Abstract
Objective: To determine whether 60 Gy is superior to standard 50 Gy for definitive concurrent chemoradiation(CCRT) in esophageal squamous cell carcinoma (ESCC) using modern radiation technology in a phase Ⅲ prospective randomized trial. Methods: From April 2013 to May 2017, 331 patients from 22 hospitals who were pathologically confirmed with stage ⅢA-ⅣA ESCC were randomized to 60 Gy or 50 Gy with random number table. Total of 305 patients were analyzed, including 152 in 60 Gy group and 153 in 50 Gy group. The median age was 63 years, 242(79.3%) males and 63(20.7%) females. The median length of primary tumor was 5.6 cm. The clinical characteristics between two groups were comparable. All patients were delivered 2 Gy per fraction, 5 fractions per week. Concurrent weekly chemotherapy with docetaxel (25 mg/m(2)) and cisplatin (25 mg/m(2)) and 2 cycles consolidation chemotherapy with docetaxel (70 mg/m(2)) and cisplatin (25 mg/m(2), d1-3) were administrated. The primary endpoint was local/regional progression-free survival (LRPFS). The data were compared with Pearson chi-square test or Fisher's exact test. Results: At a median follow-up of 27.3 months, the disease progression rate was 37.5% (57/152), 43.8% (67/153) in the high and standard-dose group, respectively (χ(2)=1.251, P=0.263). The 1, 2, 3-year LRPFS rate was 75.4%, 56.8%, 52.1% and 74.2%, 58.4%, 50.1%, respectively (HR: 0.95, 95%CI: 0.69-1.31, P=0.761). The 1, 2, 3-year overall survival rate was 84.1%, 64.8%, 54.1% and 85.4%, 62.9%, 54.0%, respectively (HR: 0.98, 95%CI: 0.71-1.38, P=0.927). The 1, 2, 3-year progression-free survival rate was 70.8%, 54.2%, 48.5% and 65.5%, 51.9%, 45.1%, respectively (HR: 0.93, 95%CI: 0.68-1.26, P=0.621). The incidence rates in toxicities between the two groups were similar except for higher rate of severe pneumonitis in high dose group (χ(2)=11.596, P=0.021). Conclusions: The efficacy in disease control is similar between 60 Gy and 50 Gy using modern radiation technology concurrent with chemotherapy for ESCC. The 50 Gy should be recommended as the regular radiation dose with CCRT for ESCC.

Abstract
Objective: To explore the relationships between serum lipoprotein-associated phospholipase A2 (Lp-PLA2) and KIM-based white matter lesion (WML) and carotid atherosclerotic plaque. Methods: From November 2018 to July 2019, 155 patients admitted to the Department of Neurology of the First Affiliated Hospital of Anhui Medical University were enrolled, with 125 cases of brain MRI manifestations of white matter lesions allocated to WML group and 30 cases of normal MRI in control group (NC group). According to KIM classification, WML patients were further divided into juxtaventricular white matter lesion (JVWML) group (n=30), periventricular white matter lesion (PVWML) group (n=33), juxtacortical white matter lesion (JCWML) group (n=30) and deep white matter lesion (DWML) group (n=32). Clinical Data of vascular risk factors in all subjects was collected and reviewed. Serum Lp-PLA2 content was determined by double-antibody sandwich enzyme-linked immunosorbent assay (ELISA). Carotid atherosclerosis plaques were detected by carotid artery ultrasonography and divided into stable and vulnerable plaques, and thus total score of each plaque was subsequently calculated according to the Crouse method. Results: The Lp-PLA2 ((117±37) ng/ml vs (95±30) ng/ml), stable Crouse plaque integral (CPI) (0 (0,2.5) vs 0) and unstable CPI (0 (0,3.4) vs 0) in the WML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 ((138±41) ng/ml) and unstable CPI (1.5(0,3.8)) in the PVWML group were significantly higher than those in the NC group (all P<0.05). Lp-PLA2 levels in the PVWML group were significantly higher than those in the JVWML group ((100±28) ng/ml) and JCWML group ((101±27) ng/ml) (all P<0.05). Correlation analysis revealed that blood glucose (r=0.600, P=0.000), triglyceride (TG) (r=0.371, P=0.034), low-density lipoprotein cholesterol (LDL-C) (r=0.367, P=0.036) and Lp-PLA2 (r=0.567, P=0.001) were positively correlated with unstable CPI in PVWML group, while it is negatively correlated with HDL-C (r=-0.368, P=0.035). Multivariate linear regression of all relevant factors and unstable CPI in the PVWML group showed that blood glucose (b=0.463, P<0.01) and Lp-PLA2 (b=0.347, P<0.05) were still positively correlated with unstable CPI. Conclusions: Serum Lp-PLA2 is an indicator of atherosclerosis, which is associated with carotid instability plaques in periventricular WML, suggesting that inflammatory mechanism plays an important role in the development of ischemic white matter lesions.

Abstract
B7-H3 is a cell surface molecule in the immunoglobulin superfamily that has been shown to perform both immunological and non-immunological functions. It has also been found that vascular endothelial growth factor (VEGF) is an important molecule in the modulation of endothelial cell behavior. In this study, we analyzed the serum expression of B7-H3 in 113 rheumatoid arthritis and systemic lupus erythematous patients using the ELISA and found a positive correlation between B7-H3 and VEGF. Next, we investigated the involvement of B7-H3 in angiogenesis using human umbilical vein endothelial cells (HUVECs) with transient knockdown of B7-H3 and an in vivo Matrigel model. Data from the in vitro experiments showed that B7-H3 increased cell proliferation, migration, and tube formation, and correlated with the expression of VEGF. Furthermore, B7-H3 affected the formation of functional vascular networks in Matrigel plugs, which were dissected from mice injected with different HUVECs. Our data suggest that B7-H3 promotes angiogenesis through the enhancement of VEGF secretion. This is the first study proposing a significant role for B7-H3 in the promotion of angiogenesis and may provide further understanding of this gene's biological function.

Abstract
Objective: To investigate the key issues in the diagnosis and treatment of foreign body aspiration in children with tracheobronchial variations. Methods: A retrospective study was performed for 11 pediatric patients who were treated in Department of Otorhinolaryngology and Head and Neck Surgery, Henan Province People's Hospital after a diagnosis of foreign body aspiration with tracheobronchial variations between January 2015 and December 2017. There were 7 males and 4 females among the 11 cases of foreign body aspiration with tracheobronchial variations, ranging between 9 months and 11 years of age. Results: Among 11 cases, the types of variationswere tracheal bronchus in 9 cases, bridging bronchus in 1 case and simple tracheal stenosis in 1 case. All of the pediatric patients were under general anesthesia, and the foreign bodies were removed by bronchoscopy successfully with no significant complications. Conclusions: The possibility of tracheobronchial variations should be considered in children with recurrent wheezing and poor efficacy of regular treatment before foreign body aspiration. Removal of foreign body via rigid bronchoscope under general anesthesia is a safe and effective treatment. These children are needed to combine the situation oftracheobronchial variations and the location of foreign bodies to guide the operation, and strengthened the perioperative treatment.

Abstract
Cytokine-amplified functional CD8+ T cells ensure effective eradication of tumors. Interleukin 36α (IL-36α), IL-36β, and IL-36γ share the same receptor complex, composed of the IL-36 receptor (IL-36R), and IL-1RAcP. Recently, we revealed that IL-36γ greatly promoted CD8+ T cell activation, contributing to antitumor immune responses. However, the underlying mechanism of IL-36-mediated CD8+ T cell activation remains understood. In the current study, we proved that IL-36β had the same effect on CD8+ T cell as IL-36γ, and uncovered that IL-36β significantly activated mammalian target of rapamycin complex 1 (mTORC1) of CD8+ T cells. When mTORC1 was inhibited by rapamycin, IL-36β-stimulated CD8+ T cell activation and expansion was drastically downregulated. Further, we elucidated that IL-36β-mediated mTORC1 activation was dependent on the pathway of phosphatidylinositol 3 kinase (PI3K)/Akt, IκB kinase (IKK) and myeloid differentiation factor 88 (MyD88). Inhibition of PI3K or IKK by inhibitor, or deficiency of MyD88, respectively, suppressed mTORC1 signal, causing arrest of CD8+ T cell activation. Additionally, it was validated that IL-36β significantly promoted mTORC1 activation and antitumor function of CD8+ tumor-infiltrating lymphocytes (TILs) in vivo, resulting in inhibition of tumor growth and prolongation of survival of tumor-bearing mice. Taken together, we substantiated that IL-36β could promote CD8+ T cell activation through activating mTORC1 dependent on PI3K/Akt, IKK and MyD88 pathways, leading to enhancement of antitumor immune responses, which laid the foundations for applying IL-36β into tumor immunotherapy.

Abstract
Objective: To explore the correlation of left heart function changes with cognitive impairment in patients with cerebral small vessel diseases (CSVD). Methods: From February 2012 to June 2018, 199 CSVD patients admitted to the Department of Neurology of the First Affiliated Hospital of Anhui Medical University were enrolled as CSVD group. A total of 103 healthy elderly persons without cognition disorders were included as normal control group (NC group). According to the diagnostic criteria, CSVD patients were divided into 112 CSVD patients with vascular cognitive impairment (CSVD-VCI group) and 87 CSVD patients without cognitive impairment (CSVD-NCI group). Neuroimaging markers of CSVD (including lacunar infarction and white matter hyperintensity) were assessed through brain MRI. Cognitive function was evaluated by The Mini-Mental State Examination (MMSE), the Cambridge Cognitive Examination-Chinese Version (CAMCOG-C), etc. Routine echocardiography was performed to evaluate left ventricular ejection fraction (LVEF), left atrial diameter (LAD) and other parameters. Results: Compared with NC group, the LVEF level was significantly decreased in CSVD group [(65±5)% and (63±6)%, respectively] (P=0.007), while LAD level was significantly increased in CSVD group (P=0.024). The LVEF level of CSVD-VCI group [(62±6)%] was significantly lower than that of CSVD-NCI group [(64±5)%] (P=0.02). Correlation analysis revealed MMSE and CAMCOG-C scores in CSVD group were positively correlated with LVEF level (r=0.210, P=0.003; r=0.238, P=0.001). Logistic regression analysis revealed that declined LVEF was an independent risk factor associated with CSVD (OR=0.937, 95%CI 0.890-0.986) and CSVD-VCI (OR=0.900, 95%CI 0.829-0.977). Conclusions: Left heart function changes play important roles in the occurrence of CSVD and severity of its cognitive impairment. The declined LVEF may represent an independent risk factor for CSVD and its cognitive impairment.

Abstract
RATIONALE Congenital internal carotid artery hypoplasia (CICAH) is rarely reported. This study aimed to discuss the epidemiological characteristics, clinical manifestation, imaging and treatment of CICAH. PATIENT CONCERNS The case was male who showed barylalia and limited abilities of the left limbs as their main clinical manifestation. This patient was diagnosed CICAH by digital subtraction angiography (DSA) and computed tomography (CT). DIAGNOSIS CICAH. INTERVENTIONS The patient underwent anti platelet aggregation, lipid-lowering, improving cerebral circulation. OUTCOMES The patient was in a stable condition after management of cerebrovascular risk. LESSONS Given the asymptomatic and congenital nature of carotid agenesis, no treatment is necessary or possible to re-establish the internal carotid artery (ICA). However, with the high risk of aneurysm and cerebrovascular insufficiency, management of cerebrovascular risk is important. Urgent radiological assessment is necessary for patients with suspicious neurological symptoms.

Abstract
Filamin A (FlnA) is an actin cross-linking protein. Previous studies have demonstrated its role in tumor progression in a wide range of cancer types. It has been reported that FlnA interacts with the DNA damage response protein, breast cancer gene 1 (BRCA1), which is a tumor suppressor gene. However, to the best of our knowledge, there are no studies evaluating the association of these genes in human carcinomas. In the present study, the immunohistochemistry of a tissue microarray was used to investigate the clinical significance of FlnA and BRCA1 expression in pathological specimens collected from 424 patients treated for breast cancer. In addition, FlnA and BRCA1 expression was downregulated in the breast cancer cell line, MCF-7, through FlnA RNA interference. FlnA expression was exhibited by cancer tissues collected from 137 patients with breast cancer, which also exhibited high expression of BRCA1 and were associated with a relatively long survival time. A significant association was identified between FlnA protein expression and tumor size, and between FlnA protein expression and progesterone receptor expression. These results suggest that BRCA1 expression could be regulated by FlnA in the breast cancer cell line, MCF-7. Overall, the present study demonstrates that FlnA expression was associated with BRAC1 expression and tumor size in breast cancer, which provides important implications for future study of FlnA in the progression of human breast cancer.

Abstract
Live performance, bone health and metabolic responses to the interaction among stocking density and dietary concentrations of total calcium (TCa) and non-phytate phosphorus (NPP) were determined on 2,232 Ross 308 female broilers over a 3-wk experimental period. From 22 d of age, birds were randomly divided into 48 groups and provided with different corn-soybean meal-based diets varying in TCa (0.70% or 0.90%) and NPP (0.28% or 0.36%) content at 1 of 2 stocking densities [28.6 (LSD, 13 broilers/m2) and 39.6 (HSD, 18 broilers/m2) kg of predicted final BW/m2 floor space], according to a 2 × 2 × 2 factorial design with 6 replications in each treatment. Regardless of NPP supplementation, a high-TCa (0.90%) diet aggravated the impact of HSD on growth (BW gain and feed efficiency, P < 0.001) and motility (gait score, P < 0.001). This might be explained by deteriorating tibia quality (relative weight, mineral composition and biomechanical property; P < 0.01), due to the involvement of decreasing duodenal absorption (type IIb sodium-phosphate co-transporter mRNA, P < 0.001) in reduced phosphorus retention (P < 0.001). On the contrary, increasing dietary NPP (0.36%), particularly if high in TCa (0.90%), boosted TCa retention (P < 0.05) by improving absorption (calcium-binding protein D28k transcription, P < 0.05) for LSD chickens, hence enhancing bone development (relative tibia weight and tibia breaking strength, P < 0.05) and leg health (walking ability, P < 0.05). Together, HSD and LSD birds show an impaired TCa tolerance and a higher TCa+NPP threshold, respectively, to allow the optimization of bone quality via altered intestinal absorption.

Abstract
BACKGROUND Clinically infarction of the columns of the fornix is very rare. It is also easy to be overlooked during imaging examination due to the special anatomical localization and features of columns of the fornix. In the meantime, with memory disorder to be its most prominent manifestation, it is very easily false diagnosed as other diseases when the lesion focus is overlooked, causing unnecessary invasive examinations like cerebrospinal fluid tests. METHODS Case report and Literature review. RESULTS We presented a 66-year-old woman with memory impairment due to a small acute infarction of the columns of the fornix. Through her diagnosis and treatment, we believed that early diagnosis and treatment were important to these patients who were enduring the disease. In addition, literature review informed us that for those unwilling to undergo cerebral angiography or for small cerebrovascular lesions that cannot be detected by angiography, 7T magnetic resonance imaging (MRI) might be an ideal diagnostic method. CONCLUSION This case illustrated the significance of MRI in diagnosis for patients with acute memory impairment. When reading MRI results, one needs to pay attention to identify small lesions at special locations. In addition, cerebral apoplexy is still the first consideration of diagnosis when acute memory impairment occurs in patients with cerebrovascular disease risk factors.

Abstract
Objective: To explore the change and value of platelet aggregability(PA)in patients with subcortical ischemic vascular disease (SIVD). Methods: A total of 108 patients with SIVD hospitalized in the Department of Neurology of the First Affiliated Hospital of Anhui Medical University from October 2015 to July 2017 were enrolled as SIVD group and 30 healthy cases were also in cluded as normal controlgroup (NC). According to magnetic resonance imaging(MRI), the SIVD group was further divided into two subtypes: lacunar infarction(LI) (n=31)and leukoaraiosis(LA) (n=77). The severity of LA was further graded according to the Fazekas scale. The maximum aggregation rate of platelets was measured by optical turbidimetry, respectively, using four arachidonic acid (ACA), two adenosine monophosphate (ADP) and collagen (COLL) as inducerin all subjects. The change of PA between the subtypes of SIVD and NC were compared, and the relationship between PA and the severity of LA was analyzed. Results: The level of PA in SIVD was significantly higher than those in NC (P<0.001). In comparison with NC, the level of PA was significantly higher in both LI and LA subgroups(P<0.05). Meanwhile, there was no significant difference between LA group and LI group (P>0.05). Moreover, between LA groups, the PA induced by COLL were significantly different between the LA3 group and the LA1 group (P=0.026). Correlation analysis showed that ageand the level of PA induced by COLL was positively correlated with LA grade (r=0.382, P=0.001; r=0.260, P=0.026). Multivariate logistic regression analysis revealed that after controlling for various factors, when induced by ACA, the risk of SIVD in the highest group (>86.80%) and higher group (82.63%-86.80%) was 13.95 and 3.09 times respectively higher than in the normal group(<82.63%), the differences were statistically significant (P<0.001, P=0.038); when induced by ADP, the risk of SIVD in the highest group (>87.63%) and higher group (82.80%-87.63%) was 20.78 and 5.85 times respectively higher than in the normal group (<82.80%), the differences were statistically significant (P<0.001, P=0.003); When induced by COLL, the risk of SIVD in the highest group (>87.60%) and higher group (83.80%-87.60%)was 28.53 and 9.02 times respectively higher than in the normal group (<83.80%), the differences were statistically significant (P<0.001, P=0.002). Conclusions: The increasedlevel of PA is an independent risk factor of SIVD and closely related with the severity of LA .This study provides a theoretical basis for further understanding of the SIVD's pathogenesis and for the prevention and treatment of SIVD in the clinical practice.

Abstract
OBJECTIVES To explore the characteristics of schizophrenia patients' homicide behaviors and the influences of the assessments of criminal capacity. METHODS Indicators such as demographic and clinical data, characteristics of criminal behaviors and criminal capacity from the suspects whom were diagnosed by forensic psychiatry as schizophrenia (n=110) and normal mental (n=70) with homicide behavior, were collected by self-made investigation form and compared. The influences of the assessments of criminal capacity on the suspects diagnosed as schizophrenia were also analyzed using logistic regression analysis. RESULTS There were no significant statistical differences between the schizophrenic group and the normal mental group concerning age, gender, education and marital status (P>0.05). There were significant statistical differences between the two groups concerning thought disorder, emotion state and social function before crime (P<0.05) and there were significant statistical differences in some characteristics of the case such as aggressive history (P<0.05), cue, trigger, plan, criminal incentives, object of crime, circumstance cognition and self-protection (P<0.05). Multivariate logistic regression analysis suggested that thought disorder, emotion state, social function, criminal incentives, plan and self-protection before crime of the schizophrenic group were positively correlated with the criminal capacity (P<0.05). CONCLUSIONS The relevant influences of psychopathology and crime characteristics should be considered comprehensively for improving the accuracy of the criminal capacity evaluation on the suspects diagnosed as schizophrenia with homicide behavior.

Abstract
Responses to stocking density (SD), dietary biotin concentration and litter condition were evaluated on 2016 Ross 308 male broilers in the fattening period (day 22-day 42). The birds were placed in 48 pens with either dry or wet litter to simulate the final stocking density of 30 kg (12 broilers/m2 ; normal stocking density, NSD) and 40 kg (16 broilers/m2 ; high stocking density, HSD) of body weight (BW)/m2 floor space. A corn-soybean meal-based diet was supplemented with biotin to provide a normal (NB; 155 μg/kg) or high (HB, 1521 μg/kg) level of dietary biotin. There were six repetitions per treatment. The inappropriate moisture content of litter associated with HSD was avoided (p < 0.05) by good management (SD difference: dry litter, 6.65% vs. wet litter, 13.23%; 42 days), which made it advantageous (p < 0.01) for footpad (SD difference: dry litter, 0.118 vs. wet litter, 0.312; weekly average value) and hock health (SD difference: dry litter, 0.090 vs. wet litter, 0.303; weekly average value) of HSD birds, but not (p > 0.05) for growth and processing yield. In HSD, the biotin effect (gains, FCR) was significantly higher (p < 0.01) than in NSD. The similar response of HSD birds to supplemental biotin was observed (p < 0.05) for lesion scores of footpad and hock in particularly finishing chickens, and a significant interaction (p < 0.01) among stocking density, biotin supplementation and litter condition existed from 35 to 42 days of age. Taken together, increasing dietary biotin improves the performance and well-being of broiler chickens stocked at high densities in litter-independent and litter-dependent manners respectively.

Abstract
OBJECTIVE To explore the effect of brain atrophy on the cognition in patients with subcortical ischemic vascular disease (SIVD). METHODS A total of 116 SIVD patients were enrolled from the Department of Neurology, First Affiliated Hospital, Anhui Medical University between September 2013 and December 2014. Lobar atrophy, leukoaraiosis (LA), lacunar infarcts (LI) and vascular risk factors were analyzed in the 116 SIVD patients who were divided into three groups according to the diagnostic criteria: non-cognitive impairment group (SIVD-NCI) , mild cognitive impairment group (SIVD-MCI) and dement group (SIVD-VaD). All patients underwent magnetic resonance imaging (MRI) with a 3.0-T system. The cognitive functions were evaluated by mini-metal state examination (MMSE), the Cambridge cognitive examination-Chinese version (CAMCOG-C), etc. A widely used visual atrophy rating method (0 to 3) was adopted to rate the severity of frontal, parietal and temporal lobe atrophy. The degree of LA and the numbers of LI in 4 brain regions (frontal, parieto-occipital, temporal, and basal ganglia) were evaluated meanwhile. RESULTS Firstly, both the SIVD-MCI and SIVD-VaD groups showed significantly higher total scores of atrophy, higher frontal lobe atrophy scores, higher LA scores and larger LI numbers than SIVD-NCI (H=6.138, P=0.013; H=45.845, P=0.000; H=36.818, P=0.000; H=37.46, P=0.000). There were no significant differences in temporal lobe atrophy scores between SIVD-NCI group and SIVD-MCI group. Parietal lobe atrophy scores also showed no differences among the three groups. Secondly, as well as total numbers of LI, total scores of atrophy and LA were negatively correlated with SIVD cognition, especially frontal lobe atrophy scores, parieto-occipital LA scores and basal ganglia LI numbers had a remarkable negative correlation with MMSE scores, CAMCOG-C scores and partial subitems in CAMCOG-C scores (P<0.005). However temporal LI numbers was absence of correlation with MMSE scores, CAMCOG-C scores and subitems in CAMCOG-C scores (P>0.005). Thirdly, education (OR= 0.787, P=0.009), total scores of LA (OR= 1.201, P=0.036) and total numbers of LI (OR= 1.221, P=0.011) remained to be associated with cognition after controlling for sex, age, education, hypertension, diabetes, smoking. While, after adjusting atrophy scores, total scores of LA had no significant association with cognition. Atrophy scores, total numbers of LI and education still showed significant association with cognition, particularly frontal lobe atrophy scores (OR= 16.082, P=0.000), but not temporal and parietal lobe atrophy scores. CONCLUSIONS Brain atrophy may be a new and independent predictive index of cognitive impairment in SIVD. Further, the effect of brain atrophy, the numbers of LI and degree of LA on cognitive decline is independent and decreases in turn.

The aim of this study was to investigate the selection of plasma exchange (PE) parameters and the safety of children with severe ricinism. The PE parameters and heparin dosage in 7 children with severe ricinism were recorded, and changes in the patients' vital signs and coagulation function were monitored before and after PE. All patients successfully completed PE. The speed of blood flow was 50-80 mL/min, speed of exchange flow was 600-800 mL/h, and isolating rate of blood plasma was 12.5-19.05%. Transmembrane pressure was stable at approximately 100 mmHg, and venous pressure was stable at approximately 95 mmHg. The first dose of heparin was 0.39 ± 0.04 mg/kg, and the maintaining heparin dose was 0.40 ± 0.05 to 0.22 ± 0.03 mg·kg(-1)·h(-1). During the PE process, mean arterial pressure, heart rate, respiratory rate, and pulse oxygen saturation were steady. After PE, the activated partial thromboplastin time and thrombin time prolonged to 2-3 times greater than that before PE. However, no bleeding tendency was seen. For children with severe ricinism, the choice of PE to eliminate the toxin from blood, tissues, and organs was safe and effective.

Abstract
We report the first catalytic asymmetric approach to octahydroindolones and a divergent enantioselective synthesis of perhydroindole alkaloids, as exemplified by lycorine-type Amaryllidaceae alkaloids (+)-α-lycorane and (+)-lycorine, from a common intermediate by using a highly concise route. The assembly of octahydroindolones employs a catalytic enantioselective 1,4-conjugate addition of nitro dienynes, followed by a TsOH-catalyzed cascade synthesis of highly functionalized enones, and a diastereoselective intramolecular Michael addition.

Abstract
The microRNA319 (miR319) family is conserved among diverse plant species. In rice (Oryza sativa L.), the miR319 gene family is comprised of two members, Osa-miR319a and Osa-miR319b. We found that overexpressing Osa-miR319b in rice resulted in wider leaf blades and delayed development. Here, we focused on the biological function and potential molecular mechanism of the Osa-miR319b gene in response to cold stress in rice. The expression of Osa-miR319b was down-regulated by cold stress, and the overexpression of Osa-miR319b led to an enhanced tolerance to cold stress, as evidenced by higher survival rates and proline content. Also, the expression of a handful of cold stress responsive genes, such as DREB1A/B/C, DREB2A, TPP1/2, was increased in Osa-miR319b transgenic lines. Furthermore, we demonstrated the nuclear localization of the transcription factors, OsPCF6 and OsTCP21, which may be Osa-miR319b-targeted genes. We also showed that OsPCF6 and OsTCP21 expression was largely induced by cold stress, and the degree of induction was obviously repressed in plants overexpressing Osa-miR319b. As expected, the down-regulation of OsPCF6 and OsTCP21 resulted in enhanced tolerance to cold stress, partially by modifying active oxygen scavenging. Taken together, our findings suggest that Osa-miR319b plays an important role in plant response to cold stress, maybe by targeting OsPCF6 and OsTCP21.

Abstract
A study was conducted to evaluate the effects of varying dietary vitamin D3 and stocking density on growing performance, carcass characteristics, bone biomechanical properties, and welfare responses in Ross (308) broilers. Experimental diets, containing 1, 10, or 20 times the NRC recommended level of vitamin D3 (200 IU/kg), were formulated with low, medium, or high vitamin D3 levels for 3 growing phases. Two stocking densities were 10 and 16 birds/m(2). One-day-old hatchlings (1,872 males) were randomly assigned to 6 pens in each treatment. Results showed that high stocking density decreased the feed intake, BW gain (P < 0.01), breast muscle yield (P = 0.010), and tibial development (P < 0.01), whereas increasing feed conversion ratio (P < 0.001), and the scores of gait, footpad and hock burn, and abdominal plumage damage (P < 0.01), particularly toward the age when birds attained their market size. Increasing dietary vitamin D3 improved the birds' walking ability and tibial quality (P < 0.05), and reduced the development of footpad or hock dermatitis and abdominal plumage damage (P < 0.01), some aspects of which were age-dependent and appeared to vary with stocking density. These data indicate that increasing supplemental vitamin D3 has a favorable effect on walking ability and welfare status of high stocking density birds, but not on performance.

Abstract
Background A wealth of published studies have been published on association between Chlamydia pneumoniae (C.pneumoniae) infection and cerebrovascular (CV) disease, but the results were inconsistent. This meta-analysis provides a systematic review of the available evidence from all serological and pathological studies of CV disease and C.pneumoniae. Methods A comprehensive research was conducted of MEDLINE, EMBASE, CNKI, WanFang technological periodical database and reference lists of articles to identify eligible case-control and cohort studies. Odds radio (OR) was calculated for each study outcome. Random effect model was used as pooling method and publication bias was estimated for the results. Results Fifty-two published studies that met criteria were selected. In case control studies, an association between C.pneumoniae infection and CV disease was revealed by serum specific IgG (OR, 1.61; 95% CI: 1.34 to 1.94), serum IgA (OR, 2.33; 95% CI: 1.76 to 3.08) and PCR technique of C.pneumoniae in peripheral blood cells (OR, 1.90; 95% CI: 1.17 to 3.07). No significant association was found in serum anti-C.pneumonae IgM seropositivity or in-situ-detection of C.pneumoniae in arterial biopsies with CV disease. Subgroup analysis by available studies suggested that C.pneumoniae may paly a role in atherosclerotic stroke, but be less significant in stroke of cardioembolism or other etiologies. Conclusion Association between C.pneumoniae infection and CV disease depends on the analytical method adopted, which seems stronger with stroke due to large artery atherosclerosis. Establishing a causal relationship between C.peumoniae infection and CV disease will require more prospective studies with combination of techniques and stratified by etiological subtypes.

Abstract
One of the key issues in cancer radiotherapy research is to sensitize tumor cells to the cell killing effects of ionizing radiation while leaving normal tissues intact. One potential approach to achieve this is gene-radiotherapy, i.e. a combination of radiation therapy and gene therapy. It is to choose certain exogenous radiation-inducible regulatory genes, for example, early growth response-1 (Egr-1), and transcript its downstream tumor-therapeutic genes under ionizing radiation so as to kill the tumor cells synergistically by the expressed gene products together after transfection and irradiation exposure. In this study, we engineered a plasmid encoding both TRAIL and endostatin under the control of the radiation-inducible Egr-1 promoter, and evaluated its anti-tumor efficacy in combination with radiotherapy. Our plasmid showed significant efficacy in up-regulating the levels of TRAIL and endostatin proteins after transfected into breast cancer cells and exposed to X-ray irradiation. The detected cellular effects in vitro manifested that TRAIL-endostatin-based gene therapy could enhance radiosensitizing effects in breast cancer cells in terms of tumor cell growth inhibition, promoting apoptosis and the induction of cell cycle arrest. In summary, our results suggest that TRAIL-endostain-targeting approach might be a promising method to sensitize solid tumors to radiation therapy.

Abstract
Dynamic processes in a gliding arc plasma generated between two diverging electrodes in ambient air driven by 31.25 kHz AC voltage were investigated using spatially and temporally resolved optical techniques. The life cycles of the gliding arc were tracked in fast movies using a high-speed camera with framing rates of tens to hundreds of kHz, showing details of ignition, motion, pulsation, short-cutting, and extinction of the plasma column. The ignition of a new discharge occurs before the extinction of the previous discharge. The developed, moving plasma column often short-cuts its current path triggered by Townsend breakdown between the two legs of the gliding arc. The emission from the plasma column is shown to pulsate at a frequency of 62.5 kHz, i.e., twice the frequency of the AC power supply. Optical emission spectra of the plasma radiation show the presence of excited N2, NO and OH radicals generated in the plasma and the dependence of their relative intensities on both the distance relative to the electrodes and the phase of the driving AC power. Planar laser-induced fluorescence of the ground-state OH radicals shows high intensity outside the plasma column rather than in the center suggesting that ground-state OH is not formed in the plasma column but in its vicinity.

Abstract
We report the first experiment carried out on an in situ setup, which allows for detection of CO(2) from catalytic CO oxidation close to a model catalyst under realistic reaction conditions by the means of planar laser-induced fluorescence (PLIF) in the mid-infrared spectral range. The onset of the catalytic reaction as a function of temperature was followed by PLIF in a steady state flow reactor. After taking into account the self-absorption of CO(2), a good agreement between the detected CO(2) fluorescence signal and the CO(2) mass spectrometry signal was shown. The observed difference to previously measured onset temperatures for the catalytic ignition is discussed and the potential impact of IR-PLIF as a detection technique in catalysis is outlined.

Abstract
Stress has been reported to activate the locus coeruleus (LC)-noradrenergic system. However, the molecular link between chronic stress and noradrenergic neurons remains to be elucidated. In the present study adult Fischer 344 rats were subjected to a regimen of chronic social defeat (CSD) for 4weeks. Measurements by in situ hybridization and Western blotting showed that CSD significantly increased mRNA and protein levels of the norepinephrine transporter (NET) in the LC region and NET protein levels in the hippocampus, frontal cortex and amygdala. CSD-induced increases in NET expression were abolished by adrenalectomy or treatment with corticosteroid receptor antagonists, suggesting the involvement of corticosterone and corticosteroid receptors in this upregulation. Furthermore, protein levels of protein kinase A (PKA), protein kinase C (PKC), and phosphorylated cAMP-response element binding (pCREB) protein were significantly reduced in the LC and its terminal regions by the CSD paradigm. Similarly, these reduced protein levels caused by CSD were prevented by adrenalectomy. However, effects of corticosteroid receptor antagonists on CSD-induced down-regulation of PKA, PKC, and pCREB proteins were not consistent. While mifeprestone and spironolactone, either alone or in combination, totally abrogate CSD effects on these protein levels of PKA, PKC and pCREB in the LC and those in the hippocampus, frontal cortex and amygdala, their effects on PKA and PKC in the hippocampus, frontal cortex and amygdala were region-dependent. The present findings indicate a correlation between chronic stress and activation of the noradrenergic system. This correlation and CSD-induced alteration in signal transduction molecules may account for their critical effects on the development of symptoms of major depression.

Abstract
Glucocorticoids affect cellular and molecular events in brains by modulating the expression of many genes during stress. In the present study, we examined the regulatory effect of corticosterone on the expression and function of the norepinephrine transporter (NET) in vitro. The results show that exposure of SK-N-BE(2)C cells to corticosterone for 14 days significantly increased mRNA (up to 43%) and protein (up to 71%) levels of NET in the concentration-dependent manner. Longer exposure (21 days) resulted in greater increases in the levels of mRNAs (up to about 160%) and proteins (up to about 250%) of the NET. The up-regulatory effect of corticosterone on NET expression lasted a persistent period after cessation of exposure. Associated with the corticosterone-induced enhancement in NET expression, there was a parallel increase in the uptake of [(3)H]norepinephrine by SK-N-BE(2)C cells. Increased NET expression and function were abolished after exposure of cells to corticosterone in combination with mifepristone or spironolactone, two specific antagonists of corticosteroid receptors. This is consistent with the hypothesis that corticosterone-induced NET up-regulation is mediated by corticosteroid receptors. Nevertheless, there was no synergistic effect for a combination of both corticosteroid receptor antagonists. A similar up-regulation of NET protein levels was also observed after exposing PC12 cells to corticosterone. The present findings demonstrate that corticosterone up-regulates the expression and function of NET in vitro, indicating the action of corticosterone on the noradrenergic phenotype may play an important role in the correlation between stress and the development of depression.

Abstract
Two experiments were conducted to study the effect of supplemental 100 g/day of live Bacillus cultures (2 x 10(11) cell of Bacillus subtilis and Bacillus licheniformis) on rumen fermentation as well as milk yield and composition in Chinese Holstein cows. In experiment 1, investigating 3 x 10 cows, milk yield and milk protein were increased by using B. licheniformis (p < 0.05) in comparison with an unsupplemented group and the B. subtilis group. Body weight was not significantly affected by Bacillus culture supplementation (p > 0.05). Percentage of milk fat and lactose was not significantly different between treatments (p > 0.05). But milk protein increased with B. licheniformis supplementation (p < 0.05). In experiment 2, carried out with three non-lactating ruminally and duodenally fistulated cows, results showed that B. licheniformis supplementation increased microbial crude protein flow into duodenum (p < 0.05) and decreased the ammonia nitrogen concentration in ruminal fluid at 0.5 h, 1 h, 3 h, 6 h after morning feeding (p < 0.05). Bacillus licheniformis supplementation increased total VFA and acetate concentration in ruminal fluid at 0.5 h, 1 h, 3 h, 6 h after morning feeding (p < 0.05). Bacillus subtilis had no significant effect on rumen fermentation characteristics, duodenal microbial N flow and ruminal apparent nutrient digestibility (p > 0.05). Bacillus licheniformis increased ruminal apparent nutrient digestibility of neutral detergent fibre, acid detergent fibre, and organic matter (p < 0.05).

Abstract
Sensitive and nonintrusive detection of HCl in reactive gas flows with high spatial and temporal resolution manner has for the first time (to our knowledge) been demonstrated using mid-infrared polarization spectroscopy (IRPS). Trace levels of HCl were prepared in an atmospheric pressure premixed CH4/O2/Ar flat flame by seeding a small amount of chloroform into the Ar flow. Detection of HCl with IRPS in the burnt region of the stoichiometric flame was performed by probing the fundamental ro-vibration transitions with a 3.2 microm tunable pulsed laser. The quantitative nature, the detection sensitivity, and the potential spectral interferences from water were investigated.
