To systematically evaluate the efficacy and safety of acupuncture versus Flunarizine hydrochloride in the treatment of migraine. Four Chinese databases(CNKI, VIP, WanFang, CBM), three English databases(Cochrane Library, EMbase, Medline) and ClinicalTrail.gov were systematically and comprehensively retrieved. The retrieval time was from the establishment of each database to January 8, 2020. Randomized controlled trial(RCT) for acupuncture versus Flunarizine in the treatment of migraine were screened out according to inclusion criteria and exclusion criteria. The included studies were evaluated with the Cochrane bias risk assessment tool. The included studies was conducted by RevMan 5.3, and the outcome indicators were evaluated for evidence quality and strength of recommendation by the GRADE system. A total of 1 033 literatures were retrieved, and 23 studies were finally included. Except for 4 multiarm tests, the total sample size was 1 548, including 785 in acupuncture group and 763 in Flunarizine group. The overall quality of the included studies was not high. Meta-analysis results showed that the acupuncture group was superior to the Flunarizine group in reduction of headache frequency(SMD=-1.00, 95%CI[-1.45,-0.54], P<0.000 1). In reduction of headache intensity, acupuncture group was superior to Flunarizine group(SMD=-1.05, 95%CI[-1.41,-0.68], P<0.000 01). In reduction of headache duration, acupuncture group was superior to Flunarizine group(SMD=-1.42, 95%CI[-1.83,-1.02], P<0.000 1). The acupuncture group was superior to Flunarizine group(MD=-0.17, 95%CI[-0.21,-0.13], P<0.000 01) in reduction of the painkillers taking frequency. The acupuncture group was superior to Flunarizine group(SMD=-0.94, 95%CI[-1.35,-0.52], P<0.000 1) in allevia-tion of paroxysmal symptoms, such as nausea and vomiting. The GRADE system showed that the evidence level of the above indicators was extremely low, and the strength of recommendation was low. As for the occurrence of adverse reactions, the adverse reactions reported in the acupuncture group included in the study were all mild adverse reactions, like drowsiness, subcutaneous bleeding, local pain, subcutaneous hematoma and dizziness needle. The available evidence showed that acupuncture has a better efficacy than Flunarizine hydrochloride in the treatment of migraine in adult patients. However, due to the high bias risk in the included studies, the conclusions of this study shall be adopted with caution, and more high-quality studies shall be carried out for verification in the future.

To evaluate the efficacy and safety of Yangxue Qingnao Granules alone or combined with calcium channel blocker in treatment of migraine. In this study, four Chinese databases(CNKI, VIP, WanFang, CBM), three English databases(Cochrane Library, EMbase, Medline) and clinical trials registration center(ClinicalTrials.gov) were retrieved. The retrieval time was from the establishment of each database to January 8, 2020. According to the set inclusion criteria and exclusion criteria,the randomized controlled trial(RCT) of Yangxue Qingnao Granules alone or combined with calcium channel blocker was selected. The "Cochrane bias risk assessment" tool was used to evaluate the quality of the included studies. RevMan 5.3 was used to conduct Meta-analysis of the included studies and grade system was used to evaluate the evidence quality of the outcome indicators. A total of 583 documents were retrieved and finally included in 23 studies, with a total sample size of 2 308 cases, 1 171 cases in the treatment group and 1 137 cases in the control group. The overall quality of the research included was not high. Meta-analysis showed that,(1)in terms of effective rate, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(RR=1.24, 95%CI[1.17, 1.32], P<0.000 01), and there was no significant difference between Yangxue Qingnao Granules and calcium channel blocker(RR=1.36, 95%CI[0.91, 2.03], P=0.14).(2)In terms of reducing headache frequency, when the unit of headache frequency was times per month, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-1.39, 95%CI[-1.83,-0.95], P<0.000 01), when the unit of headache frequency was times daily, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-2.08, 95%CI[-2.34,-1.82], P<0.000 01).(3)In terms of headache intensity, when headache intensity was scored by pain intensity, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-0.70, 95%CI[-0.81,-0.59], P<0.000 01), when headache intensity was scored by VAS score, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(MD=-1.59, 95%CI[-2.13,-1.06], P<0.000 01).(4)In terms of reducing headache duration, Yangxue Qingnao Granules combined with calcium channel blocker was better than calcium channel blocker(SMD=-3.13, 95%CI[-4.12,-2.15], P<0.000 01). GRADE system showed that the evidence level of the above outcome indicators was low and extremely low. Twelve cases of adverse reactions were reported, all of which were mild. The results showed that the combination of Yang-xue Qingnao Granules can improve the effective rate, reduce the headache frequency, the headache intensity and the headache duration, and had good safety and low incidence of adverse reactions compared with the single calcium channel blocker. However, there was no difference in the effective rate between Yangxue Qingnao Granules alone and calcium channel blocker. In view of the low quality of this study, which affects the reliability of the conclusion, it is necessary to use the conclusion of this study carefully, and more high-quality randomized controlled trials are needed to further verify in the future.

The aim of this paper was to investigate the mechanism of the active peptide DP17 of Eupolyphaga steleophaga in the treatment of hyperlipidemia rats. HPLC and MADIL-TOF/TOF-MS were used for the amino acid sequence analysis and solid-phase synthesis on the active peptide of E. steleophaga which were obtained by biomimetic enzymatic hydrolysis, separation and purification. The hyperlipidemia model was established by feeding with high-fat diet.Twenty days later, the rats in the blank group and the model group were given the saline and the rats in remaining groups were given the corresponding drugs by oral administration. After administration for 4 weeks, the levels of triglyceride(TG), total cholesterol(TC) and low density lipoprotein(LDL) in serum, the levels of TG, TC, adenosine monophosphate(AMP), adenosine triphosphate(ATP) in liver tissues and TG in feces were detected, respectively. Hematoxylin-eosin(HE) staining was used to observe the pathological changes of liver tissues. The Real-time fluorescence quantitative PCR method was used to detect the expression of acetyl coa carboxylase(ACC) and hydroxymethylglutaryl-coa reductase(HMGCR) mRNA in liver tissues. The expression of mammalian target of rapamycin(mTORC1) protein and adenosine 5'-monophosphate-activated protein kinase(AMPK) in liver tissues were detected by Western blot. The analysis showed that the amino acid sequence of active peptide from E. steleophaga was DAVPGAGPAGCHPGAGP(DP17). The results of pharmacological experiments showed that after oral administration of DP17 in rats, the levels of TG, TC and LDL in serum as well as TG and TC levels in liver tissues were significantly decreased(P<0.05), while the levels of AMP, ATP in liver tissues and TG content in feces were significantly increased(P<0.05); the liver steatosis of rats was significantly relieved; the expression of ACC, HMGCR mRNA and mTORC1 protein in liver tissues were significantly reduced, while the expression of AMPK phosphorylated protein was significantly increased(P<0.05). DP17, the active peptide of E. steleophag can significantly reduce lipid accumulation in liver tissues, and it may play a role in reducing blood lipids by regulating the energy metabolism balance in the body and activating AMPK/mTOR signaling pathway.
