[Systematic review of efficacy and safety of Angong Niuhuang Pills in adjuvant treatment of cerebral hemorrhage].

To systematically review the efficacy and safety of Angong Niuhuang Pills in adjuvant treatment of cerebral hemorrhage. CNKI, VIP, Wanfang, CBM, PubMed, EMbase, Cochrane Library were retrieved to collect the randomized controlled trial(RCT) from the time of database establishment to November 2020. Two researchers screened out the literatures and extracted the data according to the inclusion and exclusion criteria. RevMan 5.3 software was used for Meta-analysis. A total of 13 RCTs were included, involving 1 196 patients with cerebral hemorrhage, with 599 in the treatment group and 597 in the control group, and all of them were treated with internal medicine. The results of Meta-analysis showed that compared with conventional therapy, the combined administration with Angong Niuhuang Pills could improve the effective rate in patients with cerebral hemorrhage(RR=1.25, 95%CI[1.18, 1.34], P<0.000 01), the National Institutes of Health stroke scale(NIHSS)score(MD=-5.18, 95%CI[-8.12,-2.23], P=0.000 6) and Glasgow coma scale(GCS) score(MD=1.12, 95%CI[0.46, 1.78], P=0.000 9), activity of daily living(ADL)(MD=15.70, 95%CI[14.05, 17.36 ], P<0.000 01), reduce the malondialdehyde(MDA)(MD=-1.73,95%CI[-2.81,-0.64],P=0.002), but with no statistically significant difference in hematoma volume changes between the two groups. In terms of safety, the combined administration with Angong Niuhuang Pills reduced the incidence of adverse reactions compared with the single administration of conventional therapy(RR=0.40, 95%CI[0.28, 0.57], P<0.000 01), with no serious adverse events. The existing clinical study evidences show that Angong Niuhuang Pills had a good effect in adjuvant treatment of cerebral hemorrhage, and can improve the treatment efficacy, activity of daily living and symptoms of neurological deficits, and reduce oxidative stress, with a higher safety. However, the methodological quality of the included studies is not high, so the above conclusions still need to be verified with more high-quality studies.

[Effect of modified Buyang Huanwu Decoction on hemorrhagic transformation after rt-PA intravenous thrombolysis in patients with super early cerebral infarction].

To study the effect of modified Buyang Huanwu Decoction on the hemorrhagic transformation after intravenous thrombolysis of recombinant tissue type plasminogen activator(rt-PA) in patients with super early(onset time<4. 5 h) cerebral infarction. From March 2016 to July 2018,at the brain disease zone of the First Affiliated Hospital of Henan University of Traditional Chinese Medicine,212 cases of super early cerebral infarction were selected and divided into two group according to the randomized complete blocks designs: control group(106 cases) and traditional Chinese medicine group(106 cases). The control group was treated with rt-PA intravenous thrombolysis,while the traditional Chinese medicine group was treated with modified Buyang Huanwu Decoction in addition to the therapy of the control group. Both groups were treated for 14 days. Neurological deficit score,serum matrix metalloproteinase-9(MMP-9),neuron specific enolase(NSE),vascular endothelial growth factor(VEGF) and plasma cellular fibronectin(c-FN) levels,the incidence of hemorrhagic transformation,clinical efficacy and adverse drug reactions before and after treatment were compared between the two groups. According to the findings,at the 14 thday after treatment,the rank sum test of the grade data showed that the clinical efficacy of the traditional Chinese medicine group was better than that of the control group(Z =-2. 033,P = 0. 042); on the basis of χ2 test,the total efficiency of the traditional Chinese medicine group was higher than that of the control group(χ2= 4. 895,P =0. 027); the hemorrhagic transformation rate of the traditional Chinese medicine group was lower than that of the control group within14 days of treatment(χ2= 3. 962,P = 0. 047). MMP-9 levels in the traditional Chinese medicine group were lower than those in the control group at the 3 rd,5 th,7 th,10 th,14 thd after treatment(t =-2. 474,-3. 022,-5. 163,-6. 998,-9. 821; P = 0. 014,0. 003,0,0,0). The improvement of c-FN,NSE,VEGF and NIHSS scores in the traditional Chinese medicine group was superior to that of the control group after 14 days of treatment(t =-2. 343,-3. 187,-2. 129,-3. 105; P = 0. 020,0. 002,0. 034,0. 002). No obvious adverse reactions of modified Buyang Huanwu Decoction were observed during 14 days of treatment. Modified Buyang Huanwu Decoction could reduce the expressions of MMP-9,c-FN,NSE and VEGF after rt-PA intravenous thrombolysis in patients with super early cerebral infarction,and decrease the hemorrhagic transformation rate after thrombolysis,with high safety.

iTRAQ-Based Proteomics Analysis of Plasma of Myasthenia Gravis Patients Treated with Jia Wei Bu Zhong Yi Qi Decoction.

Myasthenia gravis (MG) is an autoimmune disease. A proportion of MG patients did not get satisfactory results after treatment with pyridostigmine and prednisone. Jia Wei Bu Zhong Yi Qi (Jia Wei BZYQ) decoction, a water extract from multiple herbs, has been demonstrated to be effective in the treatment of multiple "Qi deficiency type" diseases including MG in China. In this text, we investigated protein alterations in the plasma from healthy volunteers (C), MG patients without any treatment (T1), MG patients with routine western medical treatment (T2), and MG patients with combined treatments of Jia Wei BZYQ decoction and routine western medicines (T3) and identified some potential proteins involved in the pathogenesis and treatment of MG. iTRAQ (isobaric tags for relative and absolute quantitation) and 2D-LC-MS/MS (two-dimensional liquid chromatography-tandem mass spectrometry technologies) were employed to screen differentially expressed proteins. The identification, quantification, functional annotation, and interaction of proteins were analyzed by matching software and databases. In our project, 618 proteins were identified, among which 447 proteins had quantitative data. The number of differentially expressed proteins was 110, 117, 143, 115, 86, and 158 in T1 vs. C, T2 vs. C, T2 vs. T1, T3 vs. C, T3 vs. T1, and T3 vs. T2 groups, respectively. Functional annotation results showed that many differentially expressed proteins were closely associated with immune responses. For instance, some key proteins such as C-reactive protein, apolipoprotein C-III, apolipoprotein A-II, alpha-actinin-1, and thrombospondin-1 have been found to be abnormally expressed in T3 group compared to T1 group or T2 group. Interaction network analyses also provided some potential biomarkers or targets for MG management.

Buyang Huanwu Decoction (BYHWD) Enhances Angiogenic Effect of Mesenchymal Stem Cell by Upregulating VEGF Expression After Focal Cerebral Ischemia.

Buyang Huanwu decoction (BYHWD) has been used for centuries to treat paralysis and stroke. Previously, we have demonstrated that BYHWD combined with mesenchymal stem cell (MSC) transplantation attenuates ischemic injury partly by upregulating angiogenesis. However, the mechanisms of this drug for stroke treatment are not completely understood. Here, we aimed to clarify the mechanism of BYHWD on angiogenesis mediated by MSCs. Firstly, we verified microvessels with a size of 50-100 nm produced by either MSCs or MSCs treated by 500 µg/ml BYHWD. These exosomes were purified and found to be able to activate vascular endothelial growth factor (VEGF) expression in endothelial cells (ECs). Moreover, exosomes from MSCs and MSCs treated by BYHWD induced elevated microRNA (miRNA)-126 expression and reduced miR-221 and miR-222 expression. In MSCs, disruption of dicer, an enzyme responsible for miRNA maturation, by dicer small interfering RNA (siRNA), or RNase pretreatment abolished this ability of the exosomes. Additionally, exosomes from MSCs treated by BYHWD promoted VEGF and Ki-67 expression and augmented vascular density in rat brain after bilateral carotid artery ligation. In conclusion, our study revealed that BYHWD exposure augmented angiogenetic miRNA and VEGF expression in exosomes secreted by MSCs and elevated angiogenesis in rat brain.
