Objective To explore the clinical effect of two-points approach vascular stenting technique (via both the femoral artery and posterior tibial artery of the affected side) in repairing blunt popliteal artery injuries.Methods The clinical data of eleven patients with blunt popliteal arterial injuries,who were treated with two-points approach vascular stenting technique during the period from March 2011 to March 2015 as single-approach stenting repair failed,were retrospectively analyzed.First,antegrade puncture of the femoral artery on the affected side with subsequent angiography was performed to evaluate the arterial injury,when the attempt to push the guide-wire to pass the injured arterial segment by twisting manipulation failed the puncture of posterior tibial artery was immediately carried out,then,a 4-French single-bend catheter together with a goose neck snare was inserted.Guide-wire capture technique was used to gasp the guide-wire in the injured artery segment,and then the guide-wire was pulled to pass through the injured artery segment.In this way,the guide-wire working circle was reliably established,and along the guide-wire the vascular stent was inserted and delivered to the right site to repair the injured artery.A 6-French guiding catheter was inserted to perform thrombus aspiration for eliminating the distal outflow obstruction caused by thrombus.Thrombolytic therapy with small dose of urokinase through a indwelling catheter was employed for the treatment of peripheral arterial thrombosis.Results The technical success rate was 100％.Angiography revealed that partial transection of artery was detected in 7 patients,and complete transection of artery in 4 patients.A total of 16 stents were implanted.No perioperative mortality or procedure-related complication occurred.All patients were followed up for 13-24 months,with a mean of (18.7±3.8) months.In-stent thrombosis occurred in 2 patients,which was treated with thrombolytic therapy and the blood flow recovered;severe in-stent stenosis (＞70％) was seen in 3 patients,in whom the blood flow returned to normal after balloon dilation therapy;mild in-stent stenosis (＜30％) was found in 6 patients,and no special treatment was given.During the follow-up period,no stent fracture,deformation,or displacement was seen,and no patient needed to have an amputation surgery.Conclusion In treating blunt popliteal artery injuries,two-points approach vascular stenting technique can effectively reduce the operation time,rapidly recover the blood flow of the injured popliteal artery,and shorten the time of limb ischemia.This technique has very satisfactory clinical shortterm effect.

The effect of Fusarin C, a new mutagen extracted from Fusarium moniliforme,on murine peritoneal M? activation by measuring M?-mediated MTC ADCC and CS,Fusarin C could inhibit M? activation by both MAF and FDP. The inhibitory effect was dose-and time-dependent and the curves of dose-and time-response were similar in all three assays. There is, however, apparent difference in Fusarin C dose and time needed to induce significant in hibition among these assays. Significant inhibition occured at 0.4?g/ml and 0.5?g/ml for MTC and CS respectively, but 1.6?g/ml for ADCC. Similarly, the minimal period of time necessary to bring about significant inhibition was 2 hr for MTC, but 3 hr for ADCC. Finally, significance of the inhibitory effect of Fusarin C on M? anti-tumor activity in relation to carcinogenesis was discussed.

The inhibitory effect of Fusarin C,a new mutagen isolated from Fusarium moniliforme,on M? activation was investigated.The inhibitory effect of Fusarin C disappeared partially after 24 hr culture in the absence of the mycotoxin and completely after 72 hr.In addition,it could be overcome by high concentrations of M? activating factor or anti-serum to the target cells.

Objective To determine the normal ranges of N-terminal pro-brain natriuretic peptide(NT-proBNP) in normal children and children with symptoms of heart failure(HF),and to study their clinical implications.Methods Concentrations of serum NT-proBNP were determined in 80 normal children and 70 children with clinical symptoms of HF.Venous blood was taken in each subject,and plasma NT-proBNP was determined by ELISA method.Eighty normal children included 40 boys and 40 girls.Their ages ranged from 1 to 16 years old.Seventy children with HF were divided into two groups.The first group(n=45,21 males,24 females) included children with symptoms of HF caused by dilated cardiomyopathy(DCM).Their ages ranged from 1 to 16 years,and they had a left ventricular ejection fraction(LVEF) of less than 50%.The second group(n=25,11 male,14 female) consisted of children with symptoms of HF due to ventricular septal defect(VSD).Their ages ranged from 1 to 16 years,and they had an LVEF of 51%-78%.The serum NT-pro BNP levels were determined by ELISA method and LVEF was measured by echocardiography and clinical symptom score of heart failure was defined by using Ross Score.Results Serum concentration of NT-proBNP was 223.05 fmol/mL in normal children from 1 to 16 years old.NT-proBNP levels did not show a significant age-related or sex-related differences.In children with HF,the plasma NT-proBNP levels were significantly elevated(mean:1353.3 fmol/mL) compared to normal children(t=8.964 P

Objective To understand the underlying mechanism of mites-induced pediatric asthma by bioinformatic analysis on speciifc microRNA (miRNA) array and target gene screening. Methods This is a case control study of 62 pairs of dust mites-induced asthma children with age and gender matched healthy controls. Twelve pairs were randomly selected for miRNA array. The abnormal expression of miRNAs was compared between asthma and control children. The results were validated by RT-qPCR and bioinformatic analysis in remaining pairs of children. Results Six miRNAs (miRNA-151a-5p, 625-5p, 126-3p, 513a-5p, 27b-3p, 22-3p) were signiifcantly down-regulated more than two folds in dust mites-induced asthma children than those in controls. The enriched bioinformatics analysis showed that these miRNAs and their target genes CBL, PPARGC1B, ESR1, ONECUT2, EGFR, SYK, and STAT1 were related to inlfammatory cytokine signaling pathway. Conclusion It is suggested that miR-22-3p, 513a-5p, 625-5p, 27b-3p, and miRNA-target genes form a network through co-regulation to target genes to participate dust mites-induced asthma in children.

Objective: To compare the effects of needle pricking therapy plus rotating-pulling manipulation and rotating-pulling manipulation on blood velocity,angiokinesis,and blood viscosity in patients with vertebral artery type of cervical spondylosis(CSA),and discuss its mechanisms.Methods: 216 patients were randomly divided into 2 groups according to numeric representation,108cases in the treatment group were treated by needle pricking therapy plus rotating pulling manipulation,and 108 cases in the control group were treated by rotating pulling manipulation.The peak systolic blood velocity(Vpeak),end diastolic blood velocity(Vmin),pulsatile index(PI)and resistant index(RI)of the bilateral vertebral arteries(VA)and basilar arteries(BA)were examined by transcranial doppler sonography(TCD).The values of whole blood apparent viscosity and plasma viscosity of both groups were recorded.The indexes before and after treatment of both groups were compared.Results: The therapeutic effects of the above-mentioned indexes of the treatment group were significantly superior to those of the control group(P<0.05).In comparison with pre-treatment,the whole blood apparent viscosity(high,medium and low shear rates)and plasma viscosity of the treatment group post-treatment were obviously reduced(P<0.01,P<0.05).Conclusion: Needle pricking therapy combined with pulling-rotating manipulation can significantly improve VATCS patients' clinical symptoms,which may be closely related to its effects in lowering vascular blood resistance and blood viscosity and increasing cerebral blood supply.
