Objective To evaluate the effect and safety of ultrasound-guided pereutaneous thrombin injection for the treatment of iatrogenic femoral arterial pseudoaneurysm.Methods Thirty patients [6 male,24 female,age range 45-82 years,mean (63 ± 10) years] were found to have pseudoaneurysms confirmed by ultrasound between 1 and 7 days following femoral arterial puncture from July 2011 through July 2014.Results All patient had pseudoaneurysm thrombosis after the first procedure.Thrombin 200-1000 U (50 U/mL)was injected into the pseudoaneurysm under ultrasound-guidance,performed.One patient showed acute allergy 5 min after thrombin injection,which was relieved by anti-allergic therapy.No thromboembolic complications or infections occurred.Conclusions Ultrasound-guided pereutaneous thrombin injection is a safe and effective noninvasive method for the treatment of iatrogenic femoral pseudoaneurysm and should be considered as first-line therapy.

Objective To explore the validity of oxygen atomizing inhalation pulmicort respulas combined with montelukast in treating children with asthma and its role in pulmonary function and T lymphocyte subset.Methods Totally 78 cases treated in Huizhou People's Hospital from June,2014 to June,2016 were randomly divided into observation group and control group with each group of 39 cases.The control group on the basis of routine treatment with oxygen atomizing inhalation of pulmicort 1 mg,twice daily,and the observation group based on control group added Montelukast Sodium Chewable Tablets 5 mg,once daily,one week for one course.The clinical effect,pulmonary function,and level of T lymphocyte subset were compared between two groups.Results The total effective rate in the observation group was 94.70％,which was significantly higher than control group (82.05％,P ＜ 0.05).After therapy,the symptom scores of two groups were obviously decreased compared with those before therapy (P ＜ 0.05),and those of the observation group were significantly lower than control group (P ＜ 0.05);The pulmonary function of the two groups were obviously improved (P ＜ 0.05) compared with that before therapy (P ＜ 0.05),and the levels of FEV1,FVC,and FEV1/FVC in observation group were significantly higher than control group (P ＜ 0.05);The level ofT lymphocyte subset in control group showed no statistical difference compared to that before therapy,and the levels of CD4+ and CD4+/CD8+ in observation group were obviously decreased,whereas CD8+ was increased.Conclusion Oxygen atomizing inhalation pulmicort respulas combined with montelukast could effectively increase the clinical effect on children with asthma,improve pulmonary function and positively regulate immune function,which deserves clinical expansion.

Objective To evaluate the inhibitory effects of NF-κB inhibitor pyrrolidine dithiocar-bamate (PDTC) on NF-kappa B activity and the serum inflammatory mediators in hypertensive-ventricular hypertrophy-congestive heart fail?ure rats. Methods The rat model of hypertension-cardiac hypertrophy-heart failure was made from 42 male Dahl salt sen?sitive rats. Rats were randomly divided into seven groups including group A (normal diet group), group B (high salt diet group), group C (NF-κB inhibition in early stage), group D (NF-κB inhibition in hypertensive stage), group E (NF-κB inhibi?tion in cardiac hypertrophy stage of week 12) and group G (NF-κB inhibition in heart failure stage). There were six rats for each group. Rats were administrated 8%high salt diet and injected PDTC 100 mg/(kg·d)intraperitoneally according to the prescribed time. Changes of blood pressure, left ventricular end diastolic interventricular septal thickness (IVSD), left ven?tricular end diastolic posterior wall thickness (LVPWD), left ventricular end diastolic diameter (LVEDD), systolic left ventric?ular end diastolic diameter (LVESD), left ventricular ejection fraction (LVEF), heart, lung weight/ body weight ratio, NF-kappa B activity, tumor necrosis factor (TNF)-α, interleukin (IL)-6, monocyte chemotactic protein (MCP)-1 and C-reactive protein (CRP) were observed in different treatment time points of PDCT. Results Levels of NF-κB and proinflammatory cy?tokines were reduced after early administration of PDTC, and the cardiac function was also decreased. The longer the treat?ment time, the greater the protective effect on heart. PDTC can effectively control blood pressure, and block left ventricular hypertrophy and left ventricular failure in a certain extent. The effects of PDTC were limited after persistent hypertension, and myocardial hypertrophy formation accompanied by heart failure. Conclusion PDTC plays a role in prevention and treatment of hypertension, left ventricular hypertrophy and congestive heart failure in model rats. Early application of PDTC could obviously maintain the normal cardiac function in rats with heart disease.

Objective To study whether stem cell antigen-positive(Sca-1 + )cells from fetal liver can differentiate into neural cells. Methods Sca-1+ cells from male fetal liver were isolated with a magnetic cell sorting kit and transplanted into lethally irradiated female mice (2?103 cells/mouse). The donor cells and their characteristics in recipient brains were identified and detected by FISH and immunohistochemistry double-staining analysis at 2, 4, 6 months after transplantation. Results There existed many male cells in brains of female recipients, including white and gray matters, for brain, midbrain, the ependyma of the ventricular system, and the choroid plexus of the lateral ventri cle. Immunochemistry revealed that the Y chromosome-positive cells expressed many neural specific markers, including Neu N, TuJ-1 , NF-M, GFAP and so on. Statistic analysis showed that ratio of Y chromosome positive cells in brain was (4. 5 ? 0. 5) %, ratio of both Y chromosome and NeuN posi live cells (1. 2 ? 0. 3) %. ratio of both Y chromosome and GFAP positive cells (1. 0 ? 0. 2) %. There was no difference between the ratios of Y chromosome-positive cells in brains 2,4, and 6 month after transplantation. Conclusion Sca-1 + cells from fetal liver, the most of which are regarded as hemato-poietic stem cells, can differentiate into neural cells and astrocytes in the brains of adult mice and survive more than 6 months.

AIM: To explore the effects of the combined use of human telomerase reverse transcriptase (hTERT) gene antisense oligodeoxynucleotide (ASODN) and cisplatin on apoptosis of HL-60 cells. METHODS: PCR-ELISA was used to determine telomerase activity in HL-60 cells untreated or treated with ASODN, the expression levels of hTERT protein were assayed by immunofluorescence using fluoresce isothiocyanate (FITC) label. Apoptosis was detected by DNA electrophoresis and flow cytomertric cell cycle analysis. RESULTS: The expression levels of hTERT protein and telomerase activity in HL-60 cells treated with ASODN were shown to decrease with time, the DNA fragments were obviously found and the percentage of apoptosis cells was significantly enhanced in HL-60 cells with the combined use of hTERT ASODN and cisplatin compared with the combined use of hTERT sense oligodeoxynucleotide and cisplatin or cisplatin alone, respectively. CONCLUSION: Inhibition of telomerase activity by hTERT ASODN increases the cisplatin-induced apoptosis of HL-60 cells.

Embryonic stem cells (ESC) can develop into neural cells both in vivo and in vitro, this may elucidate the mechanism of nervous system development. ESC-derived uncommitted neural precursors or progenitors may play a role in future transplantation therapies for injury or deregeneration of nervous system. This article reviews embryonic stem cells differentiating into neural cells and characteristics of its gene expression.

Objective:To determine whether the bcl-2 antisense oligonucleotide (ASODN) can increase the sensitivity of NCI-H460 cell lines to docetaxel or radiation. Methods: Docetaxel in combination with bcl-2 ASODN or non-sense oligonucleotide (NSODN) was used to treat NCI-H460 cells, and then IC_~50 of docetaxel against NCI-H460 cells was determined with MTT method. In radiation group, NCI-H460 cells were divided into pure radiation, radiation plus bcl-2 ASODN, and radiation plus NSODN groups. The inhibition rates of cell growth were assayed by MTT, and the expression levels of Bcl-2 protein were assayed by immunofluorescence. Results: IC_~50 in bcl-2 ASODN plus docetaxel, pure docetaxel and NSODN plus docetaxel groups was (0.101?0.009) ?mol/L,(0.183?0.018)?mol/L, and (0.179?0.016)?mol/L, respectively. The differences between the first group and the latter 2 groups were significant (P
