Objective To investigate the effect of gypenoside on lipopolysaccharide (LPS)-mediated inflammatory response. Methods The BV2 microglia cell line was cultured in vitro. The BV2 microglia cells were divided into four groups: normal control, LPS (10 ng/ml), GP + LPS (GP 20 μg/ml, LPS 10 ng/ml), and GP (20 μg/ml). After 24 h cultivation, ELISA was used to detect the levels of tumor necrosis factor α(TNF-α), interleukin (IL)-1β, and IL-6. Immunocytochemistry staining and Western blot were used to detect the expression levels of nuclear factor (NF-κB) and suppressor of cytokine signaling 1 (SOCS-1). Results Compared with the normal control group, the release of TNF-α, IL-1β and IL-6, as well as the expression level of NF-κB in the LPS group were increased significantly (all P < 0. 001). Compared with the LPS group, the release of TNF-α, IL-1β and IL-6, as well as the expression level of NFκB were decreased significantly, while the expression level of SOCS-1 was increased significantly (P < 0. 001). There were no significant differences in the release of TNF-α, IL-1β and IL-6, as well as the expression levels of NF-κB and SOCS-1 between the GP group and normal control group (all P > 0. 05 ). Conclusions GP can significantly inhibit the LPS-mediated microglial inflammatory response. SOCS-1 protein may be involved in GP inhibiting LPS-mediated microglial inflammatory response.

Background Retinal neovascularization (RNV) is one of the major causes of blindness worldwide,but the pathogenic mechanism of this disease remains unclear, and therapeutic modalities need to be improved.Therefore,it is necessary to identify ocular protein markers with significant expression changes during RNV, thereby providing novel therapeutic targets for neovascular retinopathies.Objective This study was to investigate retinal vessel morphological characteristics and protein expression profiling in a mouse model of oxygen-induced retinopathy (OIR).Methods Forty four C57BL/6J mouse pups were randomly divided into normal control group and OIR group at postnatal day 7 (P7).The mice in the normal control group were raised under the normal air for 10 days.The mice of the OIR group were exposed to (75±2)% oxygen for 5 days.The mother mice were alternated between the two groups every day.The mice of the OIR group returned to normal air at P12.Fluorescein isothiocyanate-dextran (FITC-dextran) was retrobulbarly injected at P17 mice from both groups, and the retinal flatmounts were prepared after fixation.The FITC-dextran-labeled retinal vessels were observed and quantified;the paraffin sections of eyeballs were processed for hematoxylin and eosin staining,and the number of pre-retinal vascular cell nuclei was quantified.The total proteins were extracted from the eyes, and the expression profiling was analyzed by a customized protein array and verified by Western blot and ELISA.Results The retinal flatmounts labeled with FITC-dextran showed that the peripheral retinal microvessels in the OIR group were tortuous, disorganized with neovascular buds,and the vascular obliteration was prominent in the center of retina.Contrastly,the vessels were smooth,organized, and evenly distributed in the normal control group.The percentage of vascular obliteration area in the OIR group was (25.53±2.16)% ,which was significantly higher than (0.66±0.36)% in the normal control group (t=-27.61 ,P< 0.01).The number of pre-retinal vascular cell nuclei,as revealed by hematoxylin and eosin staining, was (28.41 ± 3.97)/slide in the OIR group, which was substantially higher than (0.16±0.31)/slide in the normal control group (t =-54.42,P<0.001).Protein array showed that 10 out of the 62 examined pro-inflammatory, pro-angiogenic cytokines exhibited more than 1.5-fold expression changes,including 3 up-regulated cytokines and 7 down-regulated cytokines;4 cytokines showed more than 2-fold expression changes,in which 3 cytokines were down-regulated and 1 cytokine was up-regulated.The differential expressions were verified by Western blot and ELISA.The expression trends of platelet factor 4 (PF-4), vascular endothelial growth factor A (VEGF-A), selectin P (SELP), vascular cell adhesion molecule 1 (VCAM-1) ,soluble tumor necrosis factor receptor Ⅱ (sTNF-RⅡ) and chemokine C-X-C motif ligand 16 (CXCL16) were consistent with those revealed by protein array.PF-4,VEGF-A and SELP were up-regulated,and the other 3 were significantly down-regulated (all at P<0.05).Conclusions Differential expression patterns of the cytokines,including PF-4,VEGF-A, SELP, VCAM-1, sTNF-RⅡ and CXCL16, are identified between normal and OIR mouse eyes.These differential expression patterns suggest that under the condition of OIR,the platelet system is activated,and proinflammatory factors are down-regulated.PF-4 might become a new target for VEGF-independent therapeutic strategy against RNV.

Objective To establish the xenotransplanted tumor model of Craniopharyngioma in chick chorioallan?toic membrane (CAM) and detect the angiogenesis ability, microvessel density (MVD) and cell proliferation of the xeno?graft. Method Craniopharyngioma tissues from surgical craniopharyngioma patients were transplanted on the CAM. An?giogenesis assay was performed and the MVD and PCNA were evaluated using immunohistochemistry following the trans?plantation. Results The tumor formation rate of adamantinomatous craniopharyngioma (ACP) and squamous papillary cra?niopharyngioma (SPCP) was 47.14% and 43.33%, respectively. There was no significant difference in tumor formation rate between ACP and SPCP(χ2=0.123,P=0.726). The CAM angiogenesis, MVD and expression of PCNA were higher in ACP than in SPCP. The expression of PCNA was positively correlated with MVD (Pearson r=0.639,P<0.001) and CAM assay score (Spearman r=0.490,P=0.001 ) in CP. Conclusion The model of human craniopharyngioma can be es?tablished in the CAM. The angiogenesis of the xenograft in the CAM can be evaluated and the craniopharyngioma xeno?graft of CAM possesses a new blood circulation and cell proliferation ability.

AIM: To study the possibility and conditions of transplacental infection of coxsackievirus B3(CVB 3) from pregnant mice to their fetuses and newborns. METHODS: Coxsackievirus B 3 strain causing balb/c mice myocardial injury(CVB 3m )was inoculated with 10 5 TCID 50 in dose into the mother mice at 6-7 days (early gestation),9-10 days (middle gestation) and 17-18 days (late gestation) of gestation, in contrast with non pregnant mice. Some placentas and fetuses were removed by caesarean section before mothers partusing; some mothers and their babies were sacrificed after parturition, and virus isolation, serological and pathological tests were performed. RESULTS: Viramiae was observed in mother mice of late gestation inoculated with CVB 3m at a fit amount on the second day after inoculation, while no newtralizing antibody to CVB 3m was detected in blood. The virus was isolated from cardiac muscles of inoculated mother mice in different gestation and the controls. The virus was also isolated from some placentas and fetuses, and both sera and cardiac muscles of infants in the late gestation (virus titer were all 10 -2 -10 -3 ). On d 7 of inoculating virus, pregnant and non pregnant mice titers of neutralizing antibody to CVB 3m in sera were all between 1160 and 1320. Under the electromicroscopy, some cardiac muscle cells of mother or infant mice appeared with morphological changes and little hollow bubbles occured in cytoplasm. The fibers broke off, and the bright and dark belts became indistinct. CONCLUSION: The amimal model, intraplacental passage of CVB 3 from pregnant mother in late gestation to fetus in mice, is a benefitial tool to study enterovirus diseases in human perinatal period.

Objective:To investigate the predictors of rebleeding three months after treatment of esophageal and gastric variceal bleeding (EGVB) in patients with hepatitis B cirrhosis and the effects of different treatments on rebleeding.Methods:From January 2018 to January 2020, the hepatitis B cirrhosis patients with first onset of EGVB in the First Hospital of Lanzhou University were enrolled and followed up for three months. The development of rebleeding, information about portal vein flow velocity and model for end-stage liver disease (MELD) scores after treatment of first bleeding were collected. The statistical analysis was conducted by chi-square test and binary logistic regression analysis. The efficacy for predictors of rebleeding was evaluated by using area under the receiver operating characteristic curve.Results:Among the 33 patients with the first EGVB, the rebleeding rate during three months follow-up was 42% (14 cases), including one patient (1/8) who underwent transjugular intrahepatic portosystemic shunt, 10 patients (10/19) were treated with therapeutic endoscopy, and three patients (3/6) were treated with vasoactive drugs. No statistically significant difference in rebleeding rates was found among the three treatment groups ( χ2=3.853, P=0.175). Portal vein flow velocity after treatment for the first onset of EGVB (odds ratio ( OR)=0.21, 95% confidence interval ( CI) 0.05 to 0.93, P=0.039) and MELD score ( OR=1.53, 95% CI 1.02 to 2.30, P=0.040) were independent predictors for the occurrence of rebleeding events during three months. When the portal vein flow velocity after treatment for the first bleeding was 19 cm/s, the area under the receiver operating characteristic curve for prediction of the occurrence of rebleeding during three months was 0.86, with the sensitivity of 92% and the specificity of 61%. Conclusion:Among the patients with hepatitis B cirrhosis and the first onset of EGVB, different treatments may have little relationship with three-month rebleeding, while portal vein flow velocity ≤19 cm/s is the main predictor for rebleeding within three months.

Objective:To describe the status and influencing factors of nurse-related empowerment perception in inpatients with chronic diseases.Methods:Totally 586 inpatients with chronic diseases from 6 class A hospitals in Shanghai from November 2019 to September 2020 were investigated by the Chinese version of Patient Perception of Patient-empowering Nurses Behaviors (PPPNBS), Self-Efficacy of Chronic Diseases (SECD6), Nurse-patient Trust Scale (NPTS), Chinese version of Chronic Illness Resource Survey (CV-CIRS) and a general information questionnaire which was designed by researchers.Results:The total score of PPPNBS was (134.98 ± 59.60) points, and the average score for each item was (6.14 ± 2.71) points. The total score of SECD6 was (38.81 ± 9.28) points. The total score of NPTS was (141.94 ± 11.42) points, and the total score of CV-CIRS was (57.90 ± 15.24) points, which were positively correlated with empowerment perception through Pearson correlation analysis. Multiple Linear Regression showed that the degree of education, the number of forms and compliance of health education, the times of admission, participation intention in medical decision-making, the dimension of Symptom Management in Self-efficacy, three dimensions of consistency, respect, and confidence in knowledge and technology in Nurse-Patient Trust degree and four dimensions of medical staff support, organization support, family and friends support, media and government support in Chronic Illness Resource were influencing factors of patients ′ empowerment perception (adjusted R 2 value was 0.636, F value was 79.441, P<0.01). Conclusions:Compared with the foreign level, the perception of nurses ′ empowerment of inpatients with chronic diseases is at a lower level, and self-efficacy, nurse-patient trust and chronic disease resource support are all at a medium level, which still need to be improved. Nurses should allow them to participate in their treatment, improve the control of life and reduce their anxiety.
