AIM: To elucidate the effects of platelet-activating factor (PAF) on eosinophil activation and the action of dexamethasone or theophylline during this process. METHODS: Eosinophils (EOS) from the peripheral blood of normal subjects were isolated. The hypodense eosinopil (HE) and normodense eosinophil (NE) were studied with electron microscopy. The effects of PAF on eosinophil activation and the action of dexamethasone or theophylline during the above process were measured. RESULTS: Hypodense eosinophil had significantly smaller individual granules than normodense eosinophil had. PAF induced eosinophil peroxidase release, and generated. Eosinophils incubated with 10~(-8) mmol/L PAF and 10~(-5) mmol/L dexamethasone released (101.17?10.32) mg/L eosinophil peroxidase (P

Objective To analyze the effect of modified Tongyou decoction combined with FOLFOX4 chemotherapy on pre-thrombus state and curative effect of patients with advanced prostatic cancer.Methods 142 patients with advanced prostatic cancer were collected,all patients were randomly divided into study group and control group,71 cases in each group.The control group was given FOLFOX4 chemotherapy and the study group was given modified Tongyou decoction on the baseis of the control group.After treatment,the serum levels of homocysteine(Hcy),D-two dimer(D-D),fibrinogen(FIB),the level of hemorrheology,clinical effect,the incidence of venous thrombosis in one years,the six month survival rate,the one year survival rate were detected in all patients.Resutls After treatment,compared with control group,the serum levels of Hcy,D-D,FIB,the whole blood high,middle and low-shear viscosities,plasma viscosity and the incidence of venous thrombosis in one years were higher in the study group and the difference was statistically significant(P<0.05);the erythrocyte deformability index,effective rate and one year survival rate were higher were higher in the study group and the difference was statistically significant(P<0.05).Conclusion The modified Tongyou decoction combined with FOLFOX4 chemotherapy in treatment of patients with advanced prostatic cancer can improve the prethrombotic state,improve the therapeutic effect,reduce the incidence of venous thrombosis and increase the one year survival rate,and have a guiding significance for clinic.

Objective: To observe the effect of ivabradine (IVA) on atrial and ventricular monophasic action potential duration (MAPD) and its proarrhythmic action at presence of sea anemone toxin-II (ATX-II) in isolated rabbit heart modelin vitro. Methods: The perfusion of isolated heart from female New Zealand white rabbit was conducted by Langendorff method in vitro. Left atrial and left ventricular endo- , epi-cardial action potential were recorded when pacing with ifxed frequency of 350 ms (in correspondence with the heart rate of 171 times/min) to observe the effect of IVA alone and ATX-II (3 nmol/L) with IVA on MAPD90. In addition, to observe the action of IVA alone and ATX-II with IVA on proarrhythmia when IVA reducing the heart rate to autonomous cardiac rhythm as (156±10) times/min. Results: IVA at (3-10) μmol/L prolonged atrial and ventricular endo- , epi-cardial MAPD90 by (15.9 ± 2.0) ms, (31.5 ± 4.0) ms and (23.9 ± 3.0) ms (n=6,P<0.01), respectively. ATX-II at 3 nmol/L prolonged atrial and ventricular MAPD90 by (36.5 ± 5.0)ms and (19.9 ± 3.0) ms, (19.5 ± 4.0) ms (n=6,P<0.01) respectively. With ATX-II treatment, IVA at (6-10) μmol/L decreased atrial MAPD90 by (14.4 ± 4.0) ms (n=6,P<0.01), it induced atrial arrhythmia. With 3 nmol/L of ATX-II treated ventricle, IVA at (3-10) μmol/L obviously prolonged endo- and epi-cardial MAPD90 by (36.2 ± 7.0) ms and (27.5 ± 5.0) ms(n=6,P<0.01), respectively. IVA didn’t increase ventricular beat-to-beat variability and transmural dispersion of MAPD90 no matter with or without ATX-II treatment, no ventricular arrhythmia occurred. Conclusion: IVA prolongs both atrial and ventricular MAPD, with increased late sodium current, IVA may induce atrial arrhythmia but not ventricular arrhythmia in experimental rabbits in vitro.

Objective To evaluate the effectiveness and safety of partial splenic embolization using polyvinyl alcohol versus gelfoam to treat hypersplenism in cirrhotic patients.Methods A literature search was performed in databases which included PubMed,Embase,Cochrane library,Sinomed,CNKI,Wangfang data and VIP for trials on partial splenic embolism using PVA or gelfoam to treat hypersplenism in cirrhotic patients.The study was censored in May 2016.After data extraction and assessment of quality,a meta-analysis was performed using the RevMan 5.3 software.Results Five studies which involved 197 patients were selected in this study.Included into the PVA group were 92 patients and the gelfoam group 105 patients.On Meta-analysis,the PVA group had a higher value of WBC a month after PSE (WMD =0.4,95％ CI:0.05 ～ 0.75,P ＜ 0.05),higher values of WBC (WMD =0.39,95％ CI:0.06 ～ 0.71,P ＜0.05) and PLT (WMD =8.08,95％ CI:1.65 ～ 14.51,P ＜ 0.05) on month 6 post-embolization.The degree of post-embolization pain was more severe (RR =1.32,95％ CI:1.14 ～ 1.54,P ＜ 0.05) and the length of painful time was longer (RR =2.01,95％ CI:1.36 ～ 2.66,P ＜0.05) in the PVA group.There were no significant differences in the values of PLT,fever and complications (all P ＞ 0.05).Conclusions PSE using PVA achieved better short-term and long-term results in hematological indicators than gelfoam.However,the degree and extent of duration of pain were significantly longer.

Objective To investigate the relationship between HbA1c in blood and IL-6 in tear fluid of the elderly patients with diabetic retinopathy ( DR ) in Shijiazhuang urban communities , and the relationship between IL-6 in tear fluid and the severity of DR. Methods The elderly people who lived more than 5 years , older than ≥45 year old. in nine urban communities of Shijiazhuang were stratified randomly sampled and received cross-sectional epidemiology questionnaire survey and OGTT. A total of 1 447 subjects (509 males and 938 females) were included. Each participant underwent epidemiological surveys and oral glucose tolerance test (OGTT), according to the 1999 WHO diabetes mellitus (DM) diagnostic criteria established. For patients who were newly or previously diagnosed as DM. HbA1c level, tear fluid IL-6 and serum IL-6 tested.The severity of DR was evaluated by fundus examination, the people were divided into normal group(NGT), non-diabetic retinopathy ( NDR ) , non-proliferative diabetic retinopathy ( NPDR ) , and proliferative diabetic retinopathy ( PDR ) . The correlation of serum IL-6 and tear fluid IL-6,blood HbA1c and tear fluid IL-6 were assessed by SPSS 19.0 statistical software. Results Concentrations of tear fluid IL-6 were (3.10 ± 1.25)pg/mL in the NGT group, (10.25 ± 3.22)pg/mL in the NDR group,(16.80 ± 5.76)pg/mL in the NPDR group,(25.11 ± 5.20)pg/mL in the PDR group(P < 0.01). SNK-q test revealed significant differences between every two groups (P < 0.01,P <0.05,P < 0.05) Concentrations of serum IL-6 were (88.04 ± 17.06)pg/mL in the NGT group,(126.38 ± 20.73) pg/mL in the NDR group, (239.83 ± 40.33)pg/mL in the NPDR group, (268.36 ± 27.72)pg/mL in the PDR group(P < 0.01). SNK-q test revealed significant differences between every two groups (P < 0.01). Tear fluid IL-6 level was positively correlated with serum IL-6 level(R = 0.756,P < 0.01). Tear fluid IL-6 level was positively correlated with blood IL-6 level (R = 0.338, P < 0.01). Conclusion The tear fluid IL-6 levels of the elderly patients with DM in Shijiazhuang urban communities , increased; with the increased severity of DR , the levels of tear fluid IL-6 gradually increase. The level of tear fluid IL-6, serum IL-6, HbA1c closely correlates with the severity of DR.
