Methods: A total of 61 stroke patients were randomized into MRI aided enclosure needling group (MRI aided acupuncture group) (n=31) and conventional acupuncture group (n=30). For patients of MRI aided acupuncture group, acupuncture needles were inserted into the subcutaneous tissues around the focus projection scalp area displayed by MRI, with the needle tips toward the center of the projection region and with two needles being about 2 cm apart, combined with other acupoints according to the concrete syndromes or symptoms. For patients of conventional acupuncture group, Motor Area (MS 6) and Sensory Area (MS 7) on the contralateral side of the focus were punctured. The treatment was conducted once daily, continuously for 30 days. Results: After treatment, of the 31 cases in MRI aided acupuncture group, 20 were cured basically, 10 responded with significant improvement of symptoms and signs, one case had some improvement. While in conventional acupuncture group, of the 30 cases, 11 were cured basically, 15 responded with striking amelioration of symptoms and signs and 4 had some amelioration. Ridit analysis showed that the therapeutic effect of MRI aided acupuncture group was significantly superior to that of conventional acupuncture group (P<0.05). After treatment, the whole blood viscosity, plasma viscosity, hematocrit, whole blood reduction viscosity, hemagglutination index, and the total score of the two groups all decreased significantly in comparison with those of pre treatment of each group, while whole blood viscosity, hematocrit, vascular sclerosis index and the total score of MRI aided acupuncture group were obviously lower than those of conventional acupuncture group (P<0.05-0.01), suggesting that the effect of the former group in bettering blood rheology was pronouncedly superior to that of conventional acupuncture group. Conclusion: MRI aided acupuncture group is obviously superior to that of conventional acupuncture group in improving clinical symptoms and signs and blood rheology in stroke patients.展开更多

Existing models of the apparent viscosity versus shear stress are numerous, and we have chosen to discuss the Carreau-Gambaruto model and the Quemada model. The comparison between models and viscosity measurements shows discordance for shear rates below a few tenths of s<sup>?1</sup>. The existence of an inflection point on the experimental curve is probably related to a system relaxation due to the rupture of red blood cells structure named rouleaux. This work suggests us to adapt these models for the weak shear rates.展开更多

However, the mechanism for this increase in myocardial blood flow (MBF) is not well defined. In small vessels and capillaries, relative blood viscosity plays a very important role in determining myocardial vascular resistance (MVR). MVR reduce is due partly to the increase in negative charge of erythrocyte surface. We therefore hypothesized that the enhancement of nutrient blood flow to zones of myocardial ischemia during NTG is partly secondary to reduced MVR and blood flow viscosity. The latter is affected by the negative charge of erythrocyte surface. Methods 6 dogs with LAD flow-limiting stenosis (group 1) and 6 dogs with LAD flow-limiting stenosis and LCx occmusion (group 2) were studied. At baseline and during intracoronary infusions of NTG (0.3-0.6 μg·kg-1·min-1), hemodynamics, MBF (mL·min-1·g-1), whole blood viscosity (WBη, mPa. S), elongation index (EI), eletrophoretic mobility of erythocytes (EME, [μ.s-1)/(V.cm-1)]) and percent wall thickening (%WT) were determined. MVR was calculated using driving pressure/MBF. Results As compared to baseline, no changes in hemodynamics were seen during NTG. MBF increased and MVR decreased significantly in normal bed, the central 25% and the entire of stenosed bed (P<0.05), with a decrease in WBη in both group 1 and group 2 dogs (18.6±9.7 % and 19.2±14.5 %, respectively). However, the % decrease in WBη was proportioned to the % increase in MBF or the % decrease in MVR only in the central 25% of stenosed bed (r=0.87, P<0.001), but not in the entire stenosed bed and normal bed. EI did not show statistically significant differences between during NTG and at baseline, but EME did increase. And the % decrease in WBη during NTG was related to the % increase in EME (r=0.83, P=0.01). Conclusions NTG reduced myocardial vascular resistance and blood viscosity due to the change of negative charge of erythrocyte surface may, in part, be the mechanism of the enhancement of nutrient blood flow to zones of myocardial ischemia. These results provide additional insights into the complex anti-ischemic effects of NTG.展开更多

Results showed that in acu moxibustion group (n=40) and medication group (n=40), the cure rates were 15% and 0, the markedly effective rates 62.5% and 12.5%, and the total effective rates 95% and 75% respectively. The therapeutic effect of acu moxibustion group was significantly superior to that of medication group (P<0.01). Following acu moxibustion treatment, the blood pressure and blood flow velocity of the brachial artery, the amplitude of the air volume wave of the wrist and the amplitude of the digital volume pulse wave increased remarkably compared with pre treatment (P<0.01), and after treatment with medication, only the blood velocity of brachial artery increased evidently in comparison with pre treatment (P<0.05). Comparison between two groups showed that values of the 4 indexes of acu moxibustion group were all significantly higher than those of medication group (P<0.01), displaying that the therapeutic effect of acu moxibustion is superior to that of medication. It provides experimental evidence for clinical effective treatment of aorto arteritis (branchiocephalic artery type) with acupuncture and moxibustion.展开更多

Results: After 2 courses of acupuncture treatment, all the above mentioned indexes and functional activity were improved significantly (P<0.05~0.01). Conclusion: Acupuncture and moxibustion of Yongquan (KI 1) has an active effect in improving stroke patients’ dyskinesia and blood rheology.
文摘Objective: To investigate the effects of low frequency electrical stimulation on monoamine neurotransmitters, cerebral blood flow and hemorheology in children with cerebral palsy. Methods: A total of 83 children with cerebral palsy were divided into the control group (n=42) and the observation group (n=41) according to the random data table, patients in the control group were treated with routine rehabilitation treatment, on this basis;the children in the observation group were treated with low-frequency electric stimulation. Before and after the treatment, the levels of monoamine neurotransmitter [dopamine (DA) and 5-hydroxy tryptamine (5-HT) and norepinephrine (NE)], cerebral blood flow [the average blood flow velocity of anterior cerebral artery (ACA), middle cerebral artery (MCA) and posterior cerebral artery (PCA)] and blood rheology index [high/low shear whole blood viscosity, plasma viscosity and fibrinogen (FIB)] of two groups were compared. Results: Before treatment, there were no significant difference of the levels of DA, 5-HT, NE, the average blood flow velocity of ACA/MCA/PCA, high/low shear whole blood viscosity, plasma viscosity and FIB between the two groups. After treatment, two groups of DA, 5-HT and NE levels were significantly higher than those in the same group before treatment, and the observation group of DA, 5-HT and NE levels were significantly higher than those of the control group, the difference was statistically significant;The average blood flow rate of ACA/MCA/PCA in the observation group after treatment was significantly higher than those in the same group before treatment;After treatment, the levels of high shear/low shear blood viscosity, plasma viscosity and FIB of the two groups were significantly lower than those in the same group before treatment, and the levels of observation group after treatment were significantly lower than that in the control group, the difference was statistically significant. Conclusion: Low frequency electrical stimulation can effectively increase the level of monoamine neurotransmitter, improve the level of cerebral blood flow and hemorheology, has an important clinical value.
文摘Objective: To investigate the influence of general anesthesia on hemorheology, hemodynamics and blood E, NE and COS levels in patients undergoing gynecological surgery. Methods: A total of 87 cases of gynecologic laparoscopic surgery in our hospital from November 2015 to June 2017 were selected as subjects,all patients underwent general anesthesia for surgery, at the time of T1, T2, T3,the index of EDI, ηP, whole blood viscosity of blood rheology (high, middle and low shear), hemodynamic indexes of HR, BP, E, NE, SPO2 and serum COS level were measured. Results: (1) Compared with T1, 87 patients' HSV, MSV, LSV, ηP, EAI levels were significantly lower in T2 and T3, the difference was statistically significant, but there was no significant changes in the EDI three times;(2) Compared with T1, the levels of HR, SBP and DBP in 87 patients were significantly increased at T2 and T3, the difference was statistically significant, while the change of SPO2 levels at three moments was not statistically significant;(3) Compared with T1, the blood E, NE and COS levels in 87 patients increased significantly at T2 and T3, and the difference was statistically significant. Conclusion:Application of general anesthesia in gynecological surgery, can significantly reduce the blood viscosity of patients, but will increase the heart rate and blood pressure and blood E, NE and COS levels, therefore, during the operation, the patient's signs should be monitored comprehensively and closely.
文摘Objective: To investigate the effect of Dan seven soft capsule on the treatment of acute hemorrhagic cerebrovascular disease and the influence of serum inflammatory factors, coagulation function and blood rheology indexes. Methods: A total of 112 cases of patients with acute hemorrhagic cerebrovascular disease, according to the random data table were divided into the control group (n=57) and observation group (n=55), the patients in the control group received routine treatment combined with edaravone, on the basis of the treatment of the control group, the observation group was treated with Dan seven soft capsule. The serum levels of inflammatory factors, coagulation function and blood rheology indexes were compared between the two groups before and after treatment. Results: Before treatment, there were no significant difference in the inflammatory factors (hs-CRP, TNF-α and IL-6), blood coagulation function (FIB, PT and APTT) and hemorheology (high cut whole blood viscosity, low cut whole blood viscosity and plasma viscosity) levels between the control group and observation group. Compared with the levels of the same group before treatment, two groups of hs-CRP, TNF-α, IL-6, FIB, high cut whole blood viscosity, low cut whole blood viscosity and plasma viscosity level after treatment were significantly decreased, and levels in the observation group were significantly lower than those in the control group;Compared with the group before treatment, the levels of PT and APTT in the two groups were significantly increased, and the observation group was significantly higher than the control group. Conclusion: Dan seven soft capsule in the treatment of acute hemorrhagic cerebrovascular disease can effectively reduce the level of serum inflammatory factors, improve coagulation function and blood rheology index, it has an important clinical value.
