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.

Objective To observe the clinical efficacy and safety of Shenxiong glucose injection and lipo PGE1 injection in treating the lower extremity arteriosclerotic occlusive disease (LEAOD).Methods 80 patients with LEAOD were randomly divided into control group and treatment group. Both groups were given conventional therapy, including reducing blood pressure, blood sugar, blood lipid and anti-infection therapy.Control group was additonally given intra-femoral arterial infusion with urokinase 150000 units plus 15mL 0.9% sodium chloride and 10 mg anisodamine alternately every other day, 5 days for one course, stopping 3 days after another course.Treatment group was treated with intravenous injection Lipo PGE1 injection plus 10 mL 0.9% sodium chloride and intravenous Shenxiong glucose injection per day for 14 days.Clinical efficacy, changes in clinical symptoms, whole blood viscosity, high sensitivity C-reactive protein(hs-CRP), fibrinogen, ankle-brachial index(ABI), the inner diameter of the dorsalis pedis and the peak systolic velocity( PSV) of dorsalis pedis were compared and analyzed pre and post-treatment.Adverse drug reactions were recorded during the treatment.ResuIts The efficiency for the patients in the treatment group (90.0%) was higher than that in control groups(72.5%) (P<0.05).The symptoms of numbness and cold limbs, whole blood viscosity, ABI, hs-CRP improved more significantly in the treatment group (P<0.05).No adverse event occurred in the treatment group and 2 patients in control group had mild dry mouth.ConcIusion Shenxiong glucose injection combined with lipo PGE1 injection for the treatment of LEAOD is effective and safe and should be introduced in clinical practice.

Objective To explore the effect of SFI in radiation-induced mice brain injury after 20 Gy cranial radiation.Methods The mice were divided into three groups:(1) control group,(2) RT-only group:the whole brain was irradiated with a dose of 20 Gy,(3) RT and SFI group:SFI at 20 ml/kg/d from 4 weeks after 20 Gy cranial radiation theraty(CRT).Results Morris water maze test showed that the latency of the irradiated group was longer than control group and SFI improved the cognitive function of mice (t =6.34,6.70,P ＜0.05).The expression of TNF-α reached to the highest level at 3 h after irradiation,and then it decreased but got the second higher level again at 4 weeks after irradiation.The expression of IL-1 β reached to the highest level at 72 h after irradiation and decreased until 4 weeks after irradiation.SFI decreased both expressions of TNF-α (t =11.34,9.70,6.07,P ＜ 0.05) and IL-1 β (t =12.27,5.70,7.52,P ＜ 0.05).Immune florescence staining showed that SFI reduced the number of activated microglia (t =12.35,8.64,7.82,P ＜ 0.05)and inhibited the translocation of p65 of microglia after irradiation.Conclusions Findings suggest that SFI may decrease microglial activation and suppress the expression of TNF-α and IL-1β by inhibiting the translocation of NF-κB p65 and then attenuate irradiation-induced brain injury.

OBJECTIVEDiscusses the distributive characters of the Creatine Kinase MM (CKMM) gene A/G Polymorphism in XinjiangUyghur, One hundred and fourtheen athletes and 441 general population of Uyghur were involved in the study.

METHODSPolymerase chain reaction-restriction fragment length polymorphism was used.

RESULTS(1) The CKMM gene A/G frequency in Uyghur general population was(AA, AG and GG) 0.497, 0.392 and 0.111, the result test by Hardy-Weinberg (H-W) equilibrium and x² = 2.72, P = 0.1, df = 2, indicated that the control group had representative. (2) AA, AG and GG genotype frequency of power-oriented athlete respectively was 0.442,0.302 and 0.256, frequency of GG genotype and G allele was higher than the control group, there were significant differences compared to thecontrol( P < 0.05, df = 2); (3) A/G genotype frequency of Endurance-oriented athletere spectively was 0.571, 0.400 and 0.029, there were nosignificant differences compared to the controls ( P > 0. 05, df = 2). (4) A/G genotype frequency of Uyghur soccer athletes respectively was0.472, 0.361 and 0.167, G allele was higher than the Endurance-oriented athlete and lower than the power-oriented athletes. and no significant differences compared to the controls( P > 0.05, df = 2).

CONCLUSIONThe results indicate that the CKMM gene GG genotype and G alleleare represented in power-oriented athletes, but don't find A/G polymorphism correlation with endurance and the football sport performance.

Objective To evaluate the cause of ischemia related to myocardial bridge (MB) by using SPECT/CT MPI and CTCA.Methods A total of 294 patients with chest pain,tightness or palpitation undergoing both CTCA and MPI were retrospectively enrolled in this study from March 2008 to March 2013.Among them,49 patients (26 males,23 females,age:32-85 (55.4± 16.6) years) had MB.Locations of MB and myocardial ischemia were recorded.Fused MPI/CTCA was analyzed.If there was no mural atherosclerotic plaque-related stenosis on CAG at the same location of coronary artery where ischemic myocardium was found,then MB was considered as the ischemic cause.Myocardial ischemia rates of different MB locations were compared by x2 test.Results Among 49 patients with MB,3 cases had MB in proximal segment of LAD,34 in mid LAD,4 in distal LAD,3 in septal branch,2 in distal LCX,1 in intermedius,and 2 in mid RCA.There were 41 cases with myocardial ischemia.Myocardial ischemia in 32 cases was caused by MB,including 23 caused by MB in mid LAD.The myocardial ischemia rates of the most common MB location (mid LAD,n =34) and other locations (n =15) were not significantly different (67.6％ (23/34) vs 60.0％ (9/15),x2 =0.27,P＞0.05).Conclusions MB is commonly found in the mid LAD.The myocardial ischemia rates caused by MB is not related the MB location.Hybrid MPI/CTCA could evaluate the sites of coronary MB and myocardial ischemia simultaneously and therefore may be useful to evaluate the relationship between MB and myocardial ischemia.

Objective To evaluate the protective effect of aminophylline on myocardium in the patients undergoing prothetic valve replacement operation of heart.Mothods Thirty patients undergoing prothetic valve replacement operation of heart were randomized to be treated either with aminophylline(n=15)or without aminophylline treatment(n=15). Aminophylline(5mg/kg)was injected intravenously at 15 minutes after induction of anesthesia.Cardiac troponin I(cTnI), cyclic adenosine monophosphate(cAMP),myeloperoxidase(MPO),ratio of aortic blood neutrophil count to coronary vein sinus blood neutrophil count,hemodynamics,time of aortic cress-clamping and other clinical data were recorded during the operation.Results There were no differences between the two groups in the major perioperative variables.Plasm cTnI concentration in both groups increased after off-clamping than that before CPB,however,it was lower in aminophylline group than that in control group.Concentration of cAMP in both groups after off-clamping was lower than that before CPB, however cAMP concentration in aminophylline group after off-clamping was higher than that in control group.Myocardial MPO activity and neutrophil count ratio after aortic off-clamping in aminophylline group was significantly lower than that in control group.Conclusion These results suggest that aminophylline is helpful to unprotection of myocardial and decreases the sequestration of neutrophil in myocardium.The mechanism of the protection may be related to the cAMP increased in myocardium.
