Objective To investigate the effect of Yiqi Huoxue Huatan Decoction(YHHD) on gene expression of vascular endothelial growth factor(VEGF), intercellular adhesion molecule 1(ICAM-1) in the colonic mucosa of ulcerative colitis rats. Methods Sixty rats were divided into six groups, namely normal control group, model control group, low-, middle- and high-dose Y HHD group(gastric gavage of YHHD in the dosage of 13, 26, 52 g·kg-1·d-1 respectively) , and Mesalazine(0.5 g·kg-1·d-1 ) group. T he rat model of ulcerative colitis was established by enema with 2, 4, 6-trinitrobenzene sulfonic acid(TNBS)mixture(2.5%TNBS and 50% ethanol). The changes in rat body weight were monitored. After treatment, pathological features of the colonic mucosa were observed under light microscope, and VEGF and ICAM-1 gene expression levels in the colonic mucosa were measured by reverse t ranscripti on polymerase chai n reaction(RT-PCR). Results Body weight was lighter, and relative gene expression levels of VEGF and ICAM-1 in the model group were significantly higher than those in the normal control group, and pathological features of the colonic mucosa was obvious, the differences being significant between the two groups(P<0.01). Compared with the model group, body weight was increased , pathological features of the colonic mucosa were relieved, and relative gene expression levels of VEGF and ICAM-1 were significantly decreased in YHHD groups(P<0.01), and high-dose YHHD showed the strongest effect. Conclusion YHHD can down-regulate the gene expression of VEGF and ICAM-1, which may be one of its therapeutic mechanisms for ulcerative colitis.

Objective: To investigate the efifcacy and safety of low dose erythropoietin (EPO) for treating the patients with acute myocardial infarction (AMI) after percutaneous coronary intervention procedure.
Methods: A total of 80 patients of acute STEMI with successful PCI were randomized into 2 groups. EPO group, the patients received intravenous EPO 6000 IU in 100 ml of normal saline at immediately and 2, 4 days after PCI. Control group, the patients received 100 ml of normal saline at the same time points. n=40 in each group. The patients were followed-up for 6 months for routine blood test, left ventricular ejection fraction (LVEF), left ventricular end-diastolic volume index (LVEDVI), left ventricular end-systolic volume index (LVESVI), the size of infarction, and plasma levels of BNP, hemoglobin. The major adverse cardiovascular events (MACE) and EPO related side effects were compared between 2 groups.
Results: The baseline condition was similar between 2 groups. With 6 months of treatment, EPO group showed obviously improved LVEF at 4 days after PCI, and decreased size of infarction, all P<0.05, while those indexes were similar in Control group, all P>0.05. In EPO group, with 6 months of treatment, LVESVI decreased from (49.76±32.65 ) ml/m2 to (34.78±19.98)
ml/m2, LVEDVI decreased from (92.23±27.65) ml/m2 to (84.52±25.76) ml/m2, all P>0.05, and in Control group, LVEDVI increased from (91.78±41.67) ml/m2 to (93.71±31.25) ml/m2, P>0.05. The incidence of MACE and EPO related side effects were similar between 2 groups, P>0.05.
Conclusion: Low dose EPO administration was effective and safe for treating AMI patients after PCI procedure.

Objective To analyze the VP1-VP4 genetic region of enterovirus 71 ( EV71 ) strains isolated from children with severe or mild hand, foot and mouth disease ( HFMD) in Shenzhen in 2012. Methods EV71 strains were isolated from five children with mild HFMD and five children with severe HFMD in Shenzhen in 2012.Reverse transcription-polymerase chain reaction ( RT-PCR) method was used to amplify the sequence of VP1-VP4 genes of EV71 strains.The sequences of the amplified products were analyzed by comparing with those of the EV71 reference strains ( A, B and C genotypes) published in Gen-Bank using nucleotide alignment, amino acid alignment and phylogenetic tree analysis.Results The homo-geneity between the EV71 strains isolated from severe and mild cases was 95.1%-98.2% in nucleotides and 99.2%-100% in amino acids.The VP1-VP4 nucleotide sequences of 5 strains isolated from severe cases and 5 strains from mild cases in Shenzhen shared 87.9%-97.8% homologies in nucleotides and 97.3%-99.9% homologies in amino acids with the genotype C EV71 reference strain.The EV71 strains isolated from children in Shenzhen were highly similar with the EV71 strain (FJ439769) isolated in Fuyang in 2008 and the one isolated in Jingdezhen in 2011 (JQ806378, C4a subtype) in nucleotide sequences.Mutations at the residue 31 in the VP1 region ( N→D ) were detected in 3 strains isolated from children with severe HFMD.Conclusion All of the 10 EV71 strains isolated in Shenzhen in 2012 belonged to the sub-genotype C4a.The mutation ( aa31 N→D) in the VP1 region of EV71 might be related to the different clinical mani-festations of HFMD cases in Shenzhen area.

Objective To investigate the diagnostic value of 64-slice CT angiography (CTA) to head and neck artery pathological changes.Methods One hundred patients with clinical suspicion of head and neck vascular lesions were retrospectively analyzed.Sixty four cases of lesions were detected by 64-slice CTA,and were checked by Digital Subtraction Angiography (DSA) within a week.First,the correlation of 64-slice CTA and DSA diagnosis of head and neck artery stenosis grade was counted.Then DSA was taken as the gold standard.The sensitivity,specificity,positive predictive value,and negative predictive value of 64-slice CTA to diagnose head and neck arteries stenosis were calculated.Results Of 64 cases of patients,2 cases of congenital vascular dysplasia,including 1 case with internal carotid artery in 2 cases,the remaining 60 patients had different degree of stenosis.The sensitivity,specificity,positive predictive value,and negative predictive value of 64-slice CTA was 95.34％,99.48％,97.62％,and 98.98％,respectively.Among 60 narrow patients,the plaque number was 205,including 88 soft plaques,56 mixed plaques,and 61 calcified plaque.Conclusions The 64-silce CTA has multiple advantages including rapid,noninvasiveness,high accuracy and safety,and high application value in the diagnosis of head and neck vascular lesions.It is worth promoting.
