ABSTRACT
Objective:To evaluate the clinical efficacy of Yangxue-Qingnao granule combined with ligustrazine injection in the treatment of wind-phlegm entering collaterals syndrome of cerebral infarction. Methods:A total of 96 patients with cerebral infarction and wind-phlegm entering collaterals syndrome to Suixi County Hospital of Traditional Chinese Medicine from January 2019 to December 2019 were selected and randomly divided into two groups by random number table method, with 48 in each group. The control group was given intravenous ligustrazine injection, and the observation group was given Yangxue-Qingnao granule on the basis of the treatment of the control group. Both groups were treated continuously for 2 weeks. TCM syndrome scores were performed before and after treatment, the National Institutes of Health Stroke Scale (NIHSS) was used to assess the degree of neurological impairment, and the Activity of Daily Living Scale (ADL) was evaluated. To evaluate the patient's quality of life, to detect the high-shear viscosity, low-shear viscosity and plasma viscosity of whole blood with an automatic hemorheology instrument. Results:The total effective rate of the observation group was 95.8% (46/48) and that of the control group was 70.8% (34/48). The difference between the two groups was statistically significant ( χ2=9.08, P<0.01). After treatment, the TCM syndrome score of the observation group was significantly lower than that of the control group ( t=3.51, P<0.01), the NIHSS score was significantly lower than that of the control group ( t=34.41, P<0.001), and the ADL score was significantly higher than that of the control group ( t=57.88, P<0.01). After treatment, the observation group's whole blood high shear viscosity [(5.04 ± 0.93)mPa?s vs. (5.64 ± 1.13)mPa?s, t=2.84], whole blood low shear viscosity [(11.32 ± 1.74)mPa?s vs. (13.39 ± 2.23)mPa?s, t=5.07] and plasma viscosity [(1.51 ± 0.33)mPa?s vs. (1.73 ± 0.47)mPa?s, t=2.65] of the observation group were significantly lower than those in the control group ( P<0.05 or P<0.01). Conclusion:Yangxue-Qingnao granule combined with ligustrazine injection can improve the neurological status and quality of life of patients with cerebral infarction syndrome of wind-phlegm entering the collaterals, and improve the clinical efficacy.
ABSTRACT
ObjectiveTo observe the variation in content of vascular endothelial growth factor （VEGF） in patients with Alzheimer's disease （AD） and to investigate efficacy of Yangxue Qingnao granule on AD and the effect on VEGF. MethodA total of 60 patients with cognitive impairment ［30 of AD and 30 of amnestic mild cognitive impairment （aMCI）］ were selected， and another 30 healthy people with Montreal Cognitive Assessment （MoCA）≥26 and age， gender， and complications insignificantly different from the patients were included as healthy control. The venous blood of aMCI group， AD group， and the healthy control group was collected at the enrollment to measure the level of serum VEGF. Then， the aMCI and AD patients were randomized into the observation group and the control group， with 30 patients in each group. The control group was given Donepezil Hydrochloride （5 mg·d-1）， while the observation group received Donepezil Hydrochloride （5 mg·d-1） and Yangxue Qingnao granule. MoCA was used to evaluate the severity of cognitive impairment. After the treatment for 6 months， the clinical efficacy and adverse reactions of the two groups were compared， and the serum VEGF levels were detected again by enzyme-linked immunosorbent assay （ELISA）. ResultThe serum content of VEGF in AD patients was significantly lower than that in aMCI patients and healthy people （P<0.05）. Serum VEGF levels in aMCI patients were significantly decreased compared with those in healthy people （P<0.05）. After treatment for 6 months， the serum VEGF level in the observation group was significantly higher than that before treatment， and was higher than that in the control group （P<0.05）. MoCA scores in the observation group were higher than those in control group （P<0.05）. The incidence of adverse reactions was insignificantly different between both groups. ConclusionThe serum levels of VEGF significantly decreased in aMCI and AD patients， suggesting that angiogenesis might be involved in the pathophysiological process of AD and correlated with the early stage of AD. Yangxue Qingnao granule， as a safe adjuvant therapy， showed ideal effect on aMCI and AD， as manifested by the improvement of cognitive function. The mechanism is the likelihood that it can elevate the expression of angiogenic factors such as VEGF， promote angiogenesis， and then improve the microcirculation of cortex.
ABSTRACT
In order to clarify the chemical constituents in Yangxue Qingnao granule, we established a rapid ultra-performance liquid chromatography/orthogonal acceleration time-of-flight mass spectrometry (UPLCQ- TOF/MSE) method. According to the high resolution MS spectra data, fragmentation ion information and retention time, 142 peaks were identified or tentatively presumed by comparison with reference standards data and literature reports. The herbal sources of these peaks were assigned. The results implied that phenolic acids, alkaloids, anthraquinones, phthalides, monoterpene glycosides were included in the main components of Yangxue Qingnao granule. The method is rapid for systematically elucidation of the constituents of Yangxue Qingnao granule and the results would facilitate the quality control of Yangxue Qingnao granule for safe and efficacious use.
ABSTRACT
@#Objective To investigate the effect of Yangxue Qingnao granule on the expression of glial fibrillary acidic protein (GFAP) in CA1 area of hippocampus in rats with vascular dementia (VD). Methods 144 Sprague-Dawley rats were randomly divided into sham opera-tion group (n=48), VD group (model group, n=48) and Yangxue Qingnao granule treatment group (treatment group, n=48). The VD model was prepared by modified Pulsineli's four-vessel occlusion. The sham operation group and the model group were given normal saline 10 ml/(kg?d) by gavage, and the treatment group was given Yangxue Qingnao granule 3.2 g/(kg?d) by gavage. The expression of GFAP in CA1 ar-ea of hippocampus was detected with immunohistochemical analysis and Western blotting method 1, 2, 4 and 8 weeks after modeling. Re-sults The expression of GFAP in CA1 area of hippocampus was significantly higher in the model group than in the sham operation group (P<0.01), and was lower in the treatment group than in the model group (P<0.05) at every time point. Conclusion Yanxue Qingnao granule could inhibit the activation and proliferation of astrocytes in rats.

ABSTRACT
Objective To investigate the effects of Yangxueqingnao Granule on the proliferation and differentiation of endogenous neural stem cells and their neuroprotective mechanism after brain ischemia. Methods Cerebral ischemia was induced in rats by temporary middle cerebral artery occlusion. Ischemic animals received Yangxue Qingnao Granule at high and low doses at days 3,7, 14,and 21 after MCAO. Neurological score and TTC staining were used to assess the neurological deficits and the volume of cerebral infarction, respectively. Immunohistochemistry was used to detect Brdu and Nestin expression in the subventricular zone(SVZ)and hippocampal dentate gyrus subgranular zone(SGZ)region. Results The rats in MCAO control group, low dose group and high dose group showed varying degrees of neurological def-icits and the volume of cerebral infarctions. The neurological defect scores and volume of cerebral infarction were signifi-cantly different at different time points in each group ( P<0.01). 2. The mean fluorescence intensity values of Brdu posi-tive cells or the Nestin positive cells in SVZ and SGZ regions were significantly different ( P< 0.01) at different time points after treatment for 3,7,14 or 21 days. The mean fluorescence intensity values of Brdu positive cells or the Nestin positive cells in SVZ and SGZ regions were significant different among low dose group, high dose group and MCAO con-trol group. The mean fluorescence intensity values of Brdu positive cells or the Nestin positive cells in SVZ and SGZ re-gions were significantly different among low dose group, High dose group and control group. High dose group significantly increased the mean fluorescence intensity values of Brdu positive cells or the Nestin positive cells in SVZ and SGZ re-gions. Conculsions Yangxue Qingnao Granule is able to promote the functional recovery and reduce the volume of cere-bral infarction in ischemic rats. Yangxue Qingnao Granule can enhance the proliferation and differentiation of endoge-nous neural stem cells in ischemic rats.
