Tissues and organs generate angiogenesis under the stimulation of angiogenic factors in physiological or pathological conditions.Multiple signal pathways including VEGF, Notch, Wnt/β-catenin, Ang1(2)/tie2 and PIK-Akt etc.have effects on various stages of angiogenesis.VEGF exerts irreplaceable effects on the whole process of angiogenesis through multiple signal pathways.Over the past few years, new progress has been made in the researches of mechanisms regulating angiogenesis through VEGF-related signal pathways both at home and abroad.These findings provide us new theoretical basis for clarification of the pathogenesis of many diseases and clinical drug development.In this article we will summarize the recent research progress in this field, hoping to provide new possibilities for the treatment of angiogenesis-related diseases.

Objective To investigate the effect of intracoronary application of tirofiban on coronary slow flow patients with acute myocardial infarction during primary percutaneous coronary intervention (PPC1).Method It was a retrospective analysis of 187 patients with acute myocardial infarction treated with PPCI in the emergency department of Beijing Anzhen Hospital enrolled in this study from January,2008 through January,2011.The patients divided into 2 groups in terms of intra-coronary administration of tirofiban (tirofiban group) and intra-coronary use of nitroglycerol (control group).Data were statistically analyzed by using SPSS 13.0 software.Categorical variables were analyzed using x2 test and continuous variables were compared by t test.Results Between two groups,there were no differences in preoperative systolic pressure (P =0.245),the rate of TIMI flow 3 (P =0.568) after PPCI and ST segment resolution (P =0.824),LVEF (P =0.275) and in-hospital mortality (P =0.502).Compared with tirofiban group,the systolic pressure was lower and the rate of using intra-aortic counter-pulsation was higher in control group.Although the incidence of slight bleeding in the control group was lower than that in the tirofiban group,no severe bleeding was observed in both groups.Conclusions The effect of intracoronary use of tirofiban was similar to that of nitroglycerol in terms of improving slow flow of coronary artery.It could safely and effectively reduce the incidence of the coronary slow flow in the patients after PPCI,but it produced a little impact on systolic pressure.It may be a better method of choice for AMI patient with low blood pressure.

Objective To observe the effect of microprismatic needle scalpel(MPNS) on headache induced by compression of greater occipital nerve or lesser occipital nerve.Methods 95 patients with headache induced by compression of occipital nerve were divided into the treatment group (50 cases, treated with MPNS) and control group (45 cases, treated with carbamazepine).Results In the treatment group, 42 cases were cured, 6 cases were effective, 2 cases were ineffective; while, those in the control group were 16 cases, 21 cases and 8 cases respectively. There was a significant difference between two groups ( P<0.01).Conclusion MPNS has an obvious effect on headache induced by compression of occipital nerves.

Objective To examine whether neonate′s cord blood T-lymphocytes is related to infant temperament.Methods Twenty-five healthy babies were randomly chosen in Changsha from Jul.2005 to Aug.2005 and their cord blood was drown when they were born. CD4+ and CD8+ counts, CD4+%, CD8+%, CD4+/ CD8+ratios were obtained using flow cytometry analysis. Infant temperament were measured after 1-4 months( mean age 2.52 months) with parent response to carey revised infant temperament questionnaire(EITQ/RITQ) administered.Results The percentage of CD4+ T-cell subsets to total lymphocytes correlated negatively with persistence scores (r=-0.43 P=0.033). However, CD8+%, CD8+ and CD4+ counts, CD4+/ CD8+ ratios were not correlated with temperament traits.Conclusions The lower CD4 %, the better infants' persistence.

OBJECTIVETo observe the impacts on the muscle strength in the patients of stroke-induced acroparalysis treated with Xunjingcuiqi needling technique.

METHODSOne hundred patients were randomized into a Xunjingcuiqi group and a routine acupuncture group, 50 cases in each group. In the routine acupuncture group, the routine acupuncture technique was adopted at the main acupoints, such as Shangxing (GV 23), Baihui (GV 20), Dicang (ST 4), Quchi (LI 11), Huantiao (GB 30) and Zusanli (ST 36), etc. In Xunjingcuiqi group, on the basis of the routine acupuncture technique, Xunjingcuiqi needling technique (pricking technique was quickly applied with the filiform needle along the running course of meridian to promote the conduction of meridian qi) was added. For the patients being hard to feel the needling sensation and with the muscle strength of 0 to 1 degree, Dongzhencuiqi technique was supplemented at shu-stream points of yang meridians (after qi arrival, the needling manipulation with limb movement was given to promote the conduction of meridian qi). The treatment was given once every day in the two groups. Ten treatments made one session. Three sessions of treatment were required. At the end of each session treatment, the muscle strength and clinical efficacy were assessed.

RESULTSIn the 1st, 2nd and 3rd sessions of treatment, 20, 24 and 36 cases achieved the 3 to 5 degrees muscle strength in Xunjingcuiqi group, respectively; and 6, 10 and 15 cases achieved the 3 to 5 degrees muscle strength in the routine acupuncture group. The differences were significant statistically in comparison of the two groups (P < 0.01, P < 0.05). The markably effective rates were 60.0% (30/50), 64.0% (32/50) and 70.0% (35/50) after the 1st, 2nd and 3rd sessions of treatment in Xunjingcuiqi group, respectively; and those were 38.0% (19/50), 44.0% (22/50) and 46.0% (23/50) in the routine acupuncture group, respectively. The differences were significant in the 1st and 3rd sessions of treatment between the two groups (both P < 0.05).

CONCLUSIONXunjingcuiqi needling technique combined with routine acupuncture achieves the apparent superior efficacy on acroparalysis induced by ischemic stroke as compared with the simple routine acupuncture. Xunjingcuiqi needling technique obviously improves muscle strength and shortens the duration of sickness.

OBJECTIVETo establish and evaluate a BA-ELISA method for the quantitative detection of cystic fibrosis transmembrane conductance regulator (CFTR) protein.

METHODSWe deliberately selected three tables of CFTR and made the synthetic peptide be expressed in E. coli, then used the antigen to immunize rabbits to obtain the anti-CFTR polyclonal serum. After that, 96 well plates were coated with the purified antibody against CFTR. The antigen CFTR which was extracted from human sperm was detected by anti-CFTR antibody labeled with biotin, horseradish peroxidase conjugated avidin, and the substrate. The concentrations of two kinds of antibodies and the experiment parameters were optimized. Thereby, the double antibody sandwich BA-ELISA method for the quantitative detection of CFTR protein was established. Furthermore, the reproducibility, specificity and so on were evaluated by clinical specimens of sperm.

RESULTSThe optimal concentration of coated anti-CFTR IgG was 4 µg/ml, while the biotin labeled anti-CFTR IgG was 10 µg/ml; the optimal blocking buffer was 1% BSA-PBST, the optimal time of the reaction between antigen and antibody was 60 min, the optimal chromogenic time was 15 min, the intra-assay and inter-assay coefficient were 2.16%-9.23% and 2.29%-11.71% respectively; The lowest detectable limit was 0.15 ng/ml; the standard curve had a good linear correlation of R2 = 0.962.

CONCLUSIONThe BA-ELISA method for the quantitative detection of CTFR protein is successfully established, and it is demonstrated that the method has strong specificity, high sensitivity and good reproducibility. It provides the basis and evidence of the further application of the method.
