Objective To study the effect of endothelial progenitor cells(EPCs) transplantation on chronic deep venous thrombosis.Methods Bone marrow-derived mouonuclear cells (BMMNCs) were isolated from rat bone marrow by ficoll and cultured with EGM-2MV medium.A rat model of chronic deep vein thrombosis was established by partial ligation of the inferior vena cava and intravenous injection of thrombosin.Model rats were randomly divided into three groups:A(n =25),EPCs group,1 ml 10~6 EPCs transplantation;B(n = 25),EGM-2MV medium group,1 ml EGM-2MV medium transplantation;C (n =25),control group,without any treatment.After transplantation,HE staining and immunohistochemical staining was conducted to detect recanalization of the inferior vena cava.Western blotting of inferior vena cava thrombosis was used to detect VEGF,bFGF protein expression changes.SPSS13.0 software was used for analysis.Results Compared with group B and C,VEGF,bFGF protein significantly increased in group A.The recanalization capillary density was significantly higher in group A than that in group B,and C (P ＜0.05).The neovascularization was identified by immunohistochemical staining using vWF antibody,as endothelial cells.Conclusions EPCs were the precursor of endothelial cells,when transplanted into the deep vein thrombos,initiating angiogenesis and accelerating organization and recanalization of vein thrombus.

Objective To study the correlation between non-alcoholic fatty liver disease (NAFLD)and glycosylated hemoglobin (HbA1 c) in middle-aged and aged population.Methods A total of 4 127 inservice workers and retirees aged 45 years old or above from one petrochemical enterprise in Ningbo were enrolled in our study.The waistline,body mass index,blood pressure,fasting blood-glucose,blood lipid profile,glutamyltranspeptidase,HbA1c and epigastrium B ultrasound were investigated.According to the quartile of HbA1c level,participants were divided into four groups,namely,Q1 group ≤5.2％,Q2 group ＞ 5.2％-5.4％,Q3 ＞ 5.4％-5.6％ and Q4 group ＞ 5.6％.The prevalence of NAFLD and clinical characteristics of each group were analyzed.Logistic regression was used to predict independent risk factors of NAFLD.Results The morbidity of NAFLD was 27.2％ with 31.9％ in male and 21％ in female,which was significantly higher in men.In Q1,Q2,Q3 and Q4 group,the prevalence of NAFLD were 18.5％ (178/961),22.8％ (185/812),25.6％ (280/1 095),38.1％ (480/1 259) respectively.With the increase of HbA1 c level,the morbidity of NAFLD increased synchronously.The age,systolic pressure,total cholesterol,low densitylipoprotein cholesterin and fasting blood-glucose were all elevated according to the increase of HbA1 c in 1 123 NAFLD patients.Multi-factor logistic regression analysis indicated that high HbAlc level was the risk factor of NAFLD (OR =1.67,95％ CI 1.15-2.43,P =0.007).Conclusion HbA1c is an independent risk factor of NAFLD and both of these are closely related to blood lipid metabolism disorder.

Objective To explore the treatment gap and influencing factors of convulsive epilepsy in rural areas of Jiangsu Province.Methods The clinical data of 7836 rural convulsive epilepsy patients screened from 2005 to 2020 were statistically analyzed,and the treatment status,treatment gap and related influencing factors of epilepsy patients were analyzed.Results A total of 7836 patients with convulsive epilepsy were enrolled in this study.The treatment gap for convulsive epilepsy in rural areas of Jiangsu Province was 69.05%.There was no significant difference in the treatment gap between different genders(P＞0.05).There were statistically significant differences in the treatment gap between age(χ2 = 12.196,P =0.007),age of onset(χ2 =58.658,P＜0.001),disease duration(χ2 =65.430,P＜0.001),seizure frequency(χ2 =171.276,P＜0.001),and hospitalization level(χ2 = 122.076,P＜0.001).Multivariate Logistic regression analysis showed that the older the age of onset was,the shorter the course of the disease was,the more frequent the seizures was,and the greater the treatment gap in patients with epilepsy was(all P＜0.05).Patients aged 45-59 years(P =0.012)and treated in municipal and county hospitals(P＜0.001)were more likely to receive regular anti-epileptic treatment.Conclusions There is a significant treatment gap for convulsive epilepsy patients in rural areas of Jiangsu Province.This may be due to insufficient awareness of epilepsy and the underdevelopment of primary healthcare institutions.

Objective To investigate the efficacy of valproic acid monotherapy in patients with convulsive epilepsy in several rural areas of Jiangsu Province,China,in 2005-2020.Methods The patients with convulsive epilepsy were given valproic acid monotherapy and follow-up management,and they were analyzed in terms of clinical features,medica-tion dose,drug efficacy,and adverse reactions.Results A total of 195 patients with convulsive epilepsy were enrolled in this study,among whom there were 117 male patients.Among these patients,48.72%were treated with valproate acid at a maximum dose of≤600 mg/d.In this study,193 patients were followed up for 1 year,with a response rate of 74.09%,and 79 patients were followed up for 5 years,with a cumulative response rate increasing to 87.34%.The incidence rate of adverse reactions gradually decreased with the increase in the course of treatment,and there was an increase in the propor-tion of patients with a subjective feeling of improvement in their conditions.Conclusion Valproic acid monotherapy has a marked clinical effect with slight adverse reactions,and thus it can be widely used in the treatment of patients with con-vulsive epilepsy in rural areas.
