Objective To evaluate effects of a fusion protein LTβR-Fc, which can block the herpesvirus entry mediator ligand (LIGHT-HVEM)signaling pathway, on ovalbumin-induced dermatitis in a mouse model. Methods Thirty BALB/c mice were randomly and equally divided into 3 groups: blank control group treated with 100 μl of sodium chloride physiological solution, model group sensitized with 100 μl of sodium chloride physiological solution containing 100 μg ovalbumin, blocker group firstly blocked with 100 μl of sodium chloride physiological solution containing 100 μg LTβR-Fc followed by sensitization with 100 μl of sodium chloride physiological solution containing 100 μg ovalbumin at 24 hours after the blocking. Disease severity was evaluated by eczema area and severity index (EASI)score, and lesional size was measured on day 0, 4, 8, 12, 15, 20, 23, 27, 31 and 34 after the first sensitization. A total of three sessions of sensitization were carried out. At the end of treatment, all the mice were sacrificed after serum was obtained from their orbital cavities. Thereafter, tissue specimens were obtained from skin lesions, and single cell suspensions of the spleen were prepared. RT-PCR was performed to detect mRNA expressions of interferon γ (IFN-γ), interleukin 4 (IL-4)and IL-5 in murine lesions, ELISA to measure IFN-γ, IL-4 and IL-5 levels in culture supernatants of murine splenocytes, as well as ovalbumin-specific and total IgE and IgG1 levels in murine sera. Results LTβR-Fc significantly suppressed inflammatory response in the mouse model of dermatitis induced by ovalbumin. Compared with the model group, the blocker group showed significantly decreased lesion area and EASI score (both P < 0.05). In addition, a significant decrease was observed in the mRNA expressions of IL-4 (0.88 ± 0.25 vs. 1.81 ± 0.25, P < 0.05), IL-5 (0.75 ± 0.15 vs. 1.24 ± 0.26, P < 0.05)and IFN-γ (0.62 ± 0.09 vs. 1.11 ± 0.19, P < 0.05)in murine lesions, and in supernatant levels of IL-4 (9.58 ± 1.44 ng/L vs. 20.12 ± 5.39 ng/L, P < 0.05), IL-5 (11.37 ± 2.02 ng/L vs. 22.77 ± 4.07 ng/L, P < 0.05)and IFN-γ (16 167 ± 950.40 ng/L vs. 23 930 ± 44.20 ng/L, P < 0.05)in the blocker group compared with the model group. The serum levels of both total IgE and ovalbumin-specific IgE were significantly lower in the blocker group than in the model group(total IgE: 27 466.67 ± 2 052.64 μg/L vs. 32 277 ± 407.53 μg/L, P < 0.05; ovalbumin-specific IgE: 1 296.33 ± 32.72 μg/L vs. 2 323.33 ± 502.43 μg/L, P < 0.05), so were those of total IgG1 (0.46 ± 0.11 μg/L vs. 0.84 ± 0.11 μg/L, P < 0.05)and ovalbumin-specific IgG1 (0.62 ± 0.11 μg/L vs. 0.86 ± 0.07 μg/L, P < 0.05). Conclusion The fusion protein LTβR-Fc can alleviate symptoms of ovalbumin-induced dermatitis in the mouse model likely by suppressing the LIGHT-HVEM signaling pathway, suggesting that this signaling pathway may serve as a target for the treatment of dermatitis(such as atopic dermatitis).

Objective:To analyze the incidence and risk factors of non-acute symptomatic portal vein thrombosis (PVT) after endoscopic gastric variceal injection (GVI) in the treatment of liver cirrhosis with gastric variceal bleeding (GVB).Methods:66 patients with GVB who were treated with GVI for the first time from July 2017 to October 2019 in Minhang Hospital Affiliated to Fudan University were retrospectively analyzed. The data of gender, age, preoperative Child-Pugh grade, preoperative platelet count, preoperative plasma D-dimer concentration, preoperative splenic length, preoperative portal vein velocity, preoperative splenic vein velocity, preoperative portal vein diameter, preoperative splenic vein diameter, treatment times, total number of injection points, total dose of sclerosing agent and tissue adhesive agent were collected. The patients were divided into PVT group and non-PVT group according to the occurrence of non-acute symptomatic PVT within one year after GVI. Univariate analysis was performed first, and then the factors with P<0.2 were included in the binary logistic regression model to screen the risk factors of PVT after GVI. Results:There were 25 cases (37.88%) in PVT group and 41 cases (62.12%) in non-PVT group. There were significant differences in D-dimer concentration, spleen length, Child-Pugh grade and total dose of sclerosing agent between the two groups ( P<0.05). The D-dimer concentration ( OR=2.319, 95% CI:1.359-3.956), spleen length ( OR=1.044, 95% CI:1.007-1.081) and total dose of sclerosing agent ( OR=1.075, 95% CI:1.004-1.152) were independent risk factors for PVT ( P<0.05). Conclusions:Preoperative D-dimer concentration, spleen length and total dose of sclerosing agent can predict the risk of PVT after GVI. In order to reduce the risk of PVT after GVI, the dose of sclerosing agent should be reduced as much as possible.

Objective Uterine intravenous leiomyomatosiswas a rare type of uterus tumors.Because of the lack of knowledge about the ultrasonic patterns of this kind of disease,misdiagnosis frequently happens.Reviewing the cases and relevant researcheswas helpful to understand the disease and figure it out inultrasonic images.Methods Six cases of patients with uterine intravenous leiomyomatosis were reviewed which werehospitalized in Beijing Obstetrics and Gynecology Hospital during 2014 to 2016.All of the patients underwentultrasound examinations before surgery.The ultrasound findings,clinical presentations and pathological features of the 6 patients were evaluated.Results In 6 patients with uterine intravenous leiomyomatosis,3 cases were solid tumors,located in the cervix region and para uterine region,withirregular veinvascular inside;3 cases performance as multiple tumorlocated in dilated uterine vein,active tumor embolus were found in inferior vena cavain one of the 3 cases.Conclusions Uterine intravenous leiomyomatosisis found to be a solid mass located in the cervix region and para uterine region.The internal fissure of solid tumor is an important feature.Tumor extending to the iliac vein and inferior vena cava in some cases.Thusit is hard to be diagnosed before surgery by ultrasonography.Moreover,transvaginal ultrasound combined with inferior vena cava ultrasonography and echocardiography has a more obvious advantage in the diagnosis of the uterine intravenous leiomyomatosis.

Objective:To investigate whether anxiety state and anxiety trait modulate specifically pain-induced brain responses by comparing the brain activations induced by painful stimulation and those by tactile stimulation in college students with different levels of anxiety state or anxiety trait.Methods:From April 2017 to September 2017, sixty-two college students were tested in Tianjin Medical University General Hospital.Each subject’s anxiety trait and anxiety state were assessed by the state-trait anxiety inventory (STAI) prior to the fMRI experiment.During the fMRI experiment, each subject received painful and tactile stimuli.Their brain responses to each stimulus were collected by the MRI scanner, and the perceived intensity rating of each stimulus was collected using the visual analogue scale (VAS). The pain and tactile brain activation values of subjects with different state anxiety levels and different trait anxiety levels were compared.The fMRI brain activation was detected using general linear model.For each type of anxiety (state or trait), two-way ANOVA was performed to detect the interaction between anxiety level and stimulus modality on brain responses and two-sample t-tests were performed to analyze the specific form of interaction in each brain region. Results:There were interactions between state anxiety and stimulation modality on the activation intensity of bilateral posterior parietal lobe, dorsolateral prefrontal lobe and other brain regions( P<0.05, cluster-level FWE corrected) .The brain responses to tactile stimuli (5.66±0.65) in these areas were significantly stronger than those to painful stimuli (1.24±0.55) in the group of middle-level anxiety state ( P<0.001), but no significant difference was found in the other two groups (both P>0.05). For anxiety trait, a few brain areas in bilateral occipital cortex showed significant interactions between anxiety level and stimulus modality.The brain responses to tactile stimuli (8.38±1.00) in these areas were significantly stronger than those to painful stimuli (3.19±1.12) in the group of high-level anxiety trait ( P=0.001), but no significant difference was found in the other two groups (both P>0.05). Conclusion:The modulatory effects of anxiety (both state and trait) on brain responses are different between painful and tactile conditions.It provides important evidence for unveiling the brain mechanisms of the specific modulation of anxiety on pain, and suggests that patients' anxiety trait and anxiety state should be considered during clinical treatment of pain.

Background and objective Pulmonary arterial hypertension (PAH) is a progressive disorder character-ized by abnormally elevated blood pressure of the pulmonary circulation. Without treatment, PAH progresses rapidly to right ventricular (RV) failure and even death. Cardiac magnetic resonance imaging (CMRI) has been an accurate and reproducible tool to assessment of RV morphology and function, which are important factors in the prognosis of patients with PAH. e aim of this study is to investigate acute RV response to inhalation of aerosolized iloprost in patients with PAH using CMRI. Method From March 2012 to March 2014, 48 patients with PAH underwent CMRI before and immediately aer inhalation of iloprost with a single dose of 20 μg over 15 min-20 min. RV function parameters derived from CMRI images were analyzed before and aer iloprost inhalation, including end-diastolic volume (EDV), end-diastolic area (EDA), end-systolic volume (ESV), end-systolic area (ESA), stroke volume (SV), ejection fraction (EF) and cardiac output (CO). Percentage of RV area change was also calculated [%RVAC=(EDA-ESA)/EDA×100%]. Wilcoxon's Sign Rank Test or Paired Samples t-Test was used to compare the dierences of RV function parameters before and aer inhalation. Results Aer iloprost inhalation, all patients showed significant decrease in RV EDV and RV ESV (P=0.007, P<0.001 respectively). Whereas, there were significant increase in RV SV (P=0.014), RV EF (P=0.009) and %RVAC (P=0.006). RV CO had no significant dierence before and aer inhalation (P=0.851). Conclusions Inhalation of iloprost can immediately improve RV function in patients with PAH, and noninvasive evaluation of the acute response with CMRI is feasibility.

Purpose To detect the expression of peroxiso-mal membrane protein 4(PXMP4)in breast cancer tissues and to explore the effect of PXMP4 on the proliferation,invasion,and epithelial-mesenchymal transition(EMT)of breast cancer cells.Methods Bioinformatics and immunohistochemistry(IHC)were used to detect the expression of PXMP4 in breast cancer tissues.In breast cancer cells,Western blot was used to detect the expression of Cyclin D1,E-cadherin,vimentin and N-cadherin after knockdown and overexpression of PMXP4.The proliferation ability of breast cancer cells was analyzed by CCK-8 and plate cloning assay.Scratch healing and Transwell assay an-alyzed the migration and invasion ability of breast cancer cells.Lentivirus was used to construct a PXMP4-silenced MCF-7 cell line,and the PXMP4-silenced MCF-7 cells were injected into the subcutaneous or tail vein of mice to observe lung metastasis and the number of subcutaneous tumors.Results Bioinformat-ics and IHC showed that the expression of PXMP4 in breast cancer tissues was significantly increased(P＜0.05),and the prognosis of breast cancer patients with high expression of PXMP4 was poor(P＜0.05).The clinicopathological analysis showed that the expression of PXMP4 was correlated with tumor grade and lymph node metastasis(P＜0.05).In vitro knock-down of PMXP4 inhibited the proliferation,invasion and EMT process of breast cancer cells(P＜0.05).Conversely,overex-pression of PXMP4 promoted the proliferation,invasion and EMT process of breast cancer cells(P＜0.05).In vivo,the number of lung metastases,the size of subcutaneous tumor,and the expression of Ki67 in tumor tissue were significantly de-creased after silenced PXMP4(P＜0.05).Conclusion PXMP4 is related to tumor grading and lymph node metastasis.PXMP4 promotes proliferation,invasion and EMT process of breast cancer cells.

Objective To evaluate the impact of community-aged care program (CACP) on cognitive function and fall risk among elderly adults.Methods A total of 91 elderly were included in Senior Apartment of Jiangxi province by cluster sampling and they were divided into the control group and the CACP group.
