ABSTRACT
ETHNOPHARMACOLOGICAL RELEVANCE: Medicinal mushrooms belonging to the Lignosus spp., colloquially known as Tiger Milk mushrooms (TMMs), are used as traditional medicine by communities across various regions of China and Southeast Asia to enhance immunity and to treat various diseases. At present, three Lignosus species have been identified in Malaysia: L. rhinocerus, L. tigris, and L. cameronensis. Similarities in their macroscopic morphologies and the nearly indistinguishable appearance of their sclerotia often lead to interchangeability between them. Hence, substantiation of their traditional applications via identification of their individual bioactive properties is imperative in ensuring that they are safe for consumption. L. tigris was first identified in 2013. Thus far, studies on L. tigris cultivar sclerotia (Ligno TG-K) have shown that it possesses significant antioxidant activities and has greater antiproliferative action against selected cancer cells in vitro compared to its sister species, L. rhinocerus TM02®. Our previous genomics study also revealed significant genetic dissimilarities between them. Further omics investigations on Ligno TG-K hold immense potential in facilitating the identification of its bioactive compounds and their associated bioactivities. AIM OF STUDY: The overall aim of this study was to investigate the gene expression profile of Ligno TG-K via de novo RNA-seq and pathway analysis. We also aimed to identify highly expressed genes encoding compounds that contribute to its cytotoxic and antioxidant properties, as well as perform a comparative transcriptomics analysis between Ligno TG-K and its sister species, L. rhinocerus TM02®. MATERIALS AND METHODS: Total RNA from fresh 3-month-old cultivated L. tigris sclerotia (Ligno TG-K) was extracted and analyzed via de novo RNA sequencing. Expressed genes were analyzed using InterPro and NCBI-Nr databases for domain identification and homology search. Functional categorization based on gene functions and pathways was performed using Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and Clusters of Orthologous Genes (COG) databases. Selected genes were subsequently subjected to phylogenetic analysis. RESULTS: Our transcriptomics analysis of Ligno TG-K revealed that 68.06% of its genes are expressed in the sclerotium; 80.38% of these were coding transcripts. Our analysis identified highly expressed transcripts encoding proteins with prospective medicinal properties. These included serine proteases (FPKM = 7356.68), deoxyribonucleases (FPKM = 3777.98), lectins (FPKM = 3690.87), and fungal immunomodulatory proteins (FPKM = 2337.84), all of which have known associations with anticancer activities. Transcripts linked to proteins with antioxidant activities, such as superoxide dismutase (FPKM = 1161.69) and catalase (FPKM = 1905.83), were also highly expressed. Results of our sequence alignments revealed that these genes and their orthologs can be found in other mushrooms. They exhibit significant sequence similarities, suggesting possible parallels in their anticancer and antioxidant bioactivities. CONCLUSION: This study is the first to provide a reference transcriptome profile of genes expressed in the sclerotia of L. tigris. The current study also presents distinct COG profiles of highly expressed genes in Ligno TG-K and L. rhinocerus TM02®, highlighting that any distinctions uncovered may be attributed to their interspecies variations and inherent characteristics that are unique to each species. Our findings suggest that Ligno TG-K contains bioactive compounds with prospective medicinal properties that warrant further investigations. CLASSIFICATION: Systems biology and omics.

ETHNOPHARMACOLOGICAL RELEVANCE: Lignosus rhinocerus (Cooke) Ryvarden (also known as Tiger Milk mushroom, TMM), is a basidiomycete belonging to the Polyporaceae family. It has been documented to be used by traditional Chinese physicians and indigenous people in Southeast Asia to treat a variety of illnesses, such as gastritis, arthritis, and respiratory conditions, as well as to restore patients' physical well-being. TMM has also been used in folk medicine to treat cancer. For example, people from the indigenous Kensiu tribe of northeast Kedah (Malaysia) apply shredded TMM sclerotium mixed with water directly onto breast skin to treat breast cancer, while Chinese practitioners from Hong Kong, China prescribe TMM sclerotium as a treatment for liver cancer. L. rhinocerus has previously been demonstrated to possess selective anti-proliferative properties in vitro, however pre-clinical in vivo research has not yet been conducted. AIM OF STUDY: This study aimed to examine the anti-tumor activities of L. rhinocerus TM02®, using two different sample preparations [cold water extract (CWE) and fraction] via various routes of administration (oral and intraperitoneal) on an MCF7-xenograft nude mouse model. This study also investigated the inhibitory effect of TM02® CWE and its fractions against COX-2 in vitro using LPS-induced RAW264.7 macrophages, on the basis of the relationship between COX-2 and metastasis, apoptosis resistance, as well as the proliferation of cancer cells. MATERIALS AND METHODS: The first preparation, L. rhinocerus TM02® sclerotium powder (TSP) was dissolved in cold water to obtain the cold water extract (CWE). It was further fractionated based on its molecular weight to obtain the high (HMW), medium (MMW) and low (LMW) molecular weight fractions. The second preparation, known as the TM02® rhinoprolycan fraction (TRF), was obtained by combining the HMW and MMW fractions. TSP was given orally to mimic the daily consumption of a supplement; TRF was administered intraperitoneally to mimic typical tumorous cancer treatment with a rapid and more thorough absorption through the peritoneal cavity. Another experiment was conducted to examine changes in COX-2 activity in LPS-induced RAW264.7 macrophages after a 1-h pre-treatment with CWE, HMW, and MMW. RESULTS: Our results revealed that intraperitoneal TRF-injection (90 µg/g BW) for 20 days reduced initial tumor volume by â¼64.3% (n = 5). The percentage of apoptotic cells was marginally higher in TRF-treated mice vs. control, suggesting that induction of apoptosis as one of the factors that led to tumor shrinkage. TSP (500 µg/g BW) oral treatment (n = 5) for 63 days (inclusive of pre-treatment prior to tumor inoculation) effectively inhibited tumor growth. Four of the five tumors totally regressed, demonstrating the effectiveness of TSP ingestion in suppressing tumor growth. Although no significant changes were found in mouse serum cytokines (TNF-α, IL-5, IL-6 and CCL2), some increasing and decreasing trends were observed. This may suggest the immunomodulatory potential of these treatments that can directly or indirectly affect tumor growth. Pre-treatment with CWE, HMW and MMW significantly reduced COX-2 activity in RAW264.7 macrophages upon 24 h LPS-stimulation, suggesting the potential of L. rhinocerus TM02® extract and fractions in regulating M1/M2 polarization. CONCLUSION: Based on the findings of our investigation, both the rhinoprolycan fraction and crude sclerotial powder from L. rhinocerus TM02® demonstrated tumor suppressive effects, indicating that they contain substances with strong anticancer potential. The antitumor effects of L. rhinocerus TM02® in our study highlights the potential for further explorations into its mechanism of action and future development as a prophylactic or adjunct therapeutic against tumorous cancer.

ABSTRACT
Objective:To explore the prescription and medication law of Traditional Chinese Medicine (TCM) compounds in the treatment of vascular dementia (VD) based on patent database.Methods:TCM compounds with patents about VD were retrieved from Chinese patent announcement website of the State Intellectual Property Office and CNKI. The retrieval time was from the establishment to the databases to 31 st, March 2022. The frequency, clusteringand association analysis were carried out with the help of TCM inheritance auxiliary platform (V2.5). The medication law was analyzed. Results:154 TCM compound patents for the treatment of vascular dementia were screened, involving 227 kinds of Chinese materia medica. Among them, Acori Tatarinowii Rhizoma (44 times, 28.57%) was used more frequently, and the common medicinal pair was Salviea Miltiorrhizae Radix et Rhizoma- Acori Tatarinowii Rhizoma (17 times, 11.03%). The medicinal property was mainly warm, the taste was mainly sweet, and the meridian was mainly liver meridian. Those with high confidence based on association rules were " Corni Fructus -Acori Tatarinowii Rhizoma" (0.90), " Corni Fructus -Rehmannize Radix et Praeparata" (0.90). Based on the complex network, it was concluded that the core drugs were 14 groups such as " Rehmannize Radix et Praeparata- Cistanches Herba- Corni Fructus". The new prescriptions extracted by entropy cluster analysis included 7 groups such as " Rehmannize Radix et Praeparata, Cistanches Herba, Corni Fructus and Asparagi Radix". Conclusion:The treatment of VD by TCM compounds with national patents is mainly based on tonifying deficiency, promoting blood circulation and removing blood stasis, eliminating phlegm and dampness, expelling wind and dredging collaterals, opening orifices and resuscitation, which can provide reference for clinical practice and new drug research and development.

ABSTRACT
OBJECTIVE@#To observe the effect of acupuncture combined with infantile tuina on intestinal flora and its efficacy in children with tic disorders (TD), and to explore its mechanism.@*METHODS@#A total of 15 children with TD were recruited as an observation group and 10 healthy children as a healthy control group. Regulating spleen and stomach acupuncture combined with infantile tuina were received in the observation group. First, acupuncture was applied to Zhongwan (CV 12), Tianshu (ST 25), Guanyuan (CV 4), Hegu (LI 4), Zusanli (ST 36), etc., and then abdominal massage and other tuina techniques were applied, once a day, 6 times a week, 2 weeks as a course of treatment, a total of 2 courses of treatment were required. No intervention was given in the healthy control group. In the observation group, Yale global tic severity scale (YGTSS) score and TCM syndrome score were compared before treatment and after 1 and 2 courses of treatment. 16S rRNA sequencing technology was used to detect the intestinal flora in the healthy control group and before and after treatment in the observation group.@*RESULTS@#After 1 and 2 courses of treatment, the scores of YGTSS and TCM syndrome in the observation group were lower than those before treatment (P<0.01, P<0.05). Compared with the healthy control group, the number of operational taxonomic units (OTU) and indexes of Chao1, Sobs, Ace and Shannon were decreased in the observation group before treatment (P<0.05, P<0.01). Compared with before treatment, the number of OTU and indexes of Chao1, Sobs, Ace and Shannon were increased in the observation group after treatment (P<0.01, P<0.05). Compared with the healthy control group, the relative abundance of Firmicutes in the observation group before treatment was decreased (P<0.001), while the relative abundance of Bacteroidetes, Bacteroides and Erysipelatoclostridium was increased (P<0.001, P<0.05). Compared with before treatment, the relative abundance of Bacteroidetes in the observation group was decreased (P<0.001) after treatment, while the relative abundance of Actinobacteria, Bifidobacterium and Atopobium was increased (P<0.05, P<0.01).@*CONCLUSION@#Acupuncture combined with infantile tuina based on the principle of regulating spleen and stomach could effectively improve TD symptoms in children, which may be related to regulating the diversity of intestinal flora, increasing beneficial bacteria, maintaining intestinal microecological balance, and playing a role in improving neurological disorders.

OBJECTIVE: To evaluate the effects of moxa-burning heat stimulating acupoints Zusanli (ST36) and Shenshu (BL23) on macrophage migration inhibitory factor (MIF) and its related molecules which can provide scientific experimental basis for the clinical application of moxibustion treatment of rheumatoid arthritis (RA). METHODS: Thirty rabbits were randomly assigned to control group, RA model (established by injecting Freund's Complete Adjuvant) group (RA group) and RA model with moxibustion group [Moxa group, Zusanli (ST36) and Shenshu (BL23), 5 moxa pillars/day, 6 d × 3]. The expressions of MIF mRNA were evaluated with reverse transcription polymerase chain reaction; the apoptosis rates of macrophages were detected by erminal deoxynucleotidyl transferase-mediated dTUP nick end labeling; the expressions of related signal molecules were detected with immunohistochemical S-P method and the levels of IL-2 were detected with enzyme-linked immunosorbent assay. RESULTS: The expressions of MIF mRNA, extracellular regulated protein kinases 2, p38 mitogen-activated protein kinase and nuclear factor-κ-gene binding p65 in synovial tissue of RA group were significantly increased when compared with control group, which were lower remarkably in moxa group than those in RA group. The apoptosis rates of macrophages in RA group were significantly down-regulated as compared with the control group, which were up-regulated in moxa group compared with the RA group. The levels of IL-2 in synovial fluid from the RA group were elevated significantly as compared with that from control group, but those of the moxa group were reduced when compared with those from RA group. CONCLUSIONS: Moxibustion may simultaneously regulate the expressions of MIF and its related signaling pathways molecules, the apoptosis rate of macrophages in synovial tissue, as well as the level of inflammatory factors in synovial fluid. The results suggest that the anti-inflammatory effect of moxibustion on RA may be related to inhibit the expression of MIF in synovial tissue, the molecules of some related signaling pathways and promote the apoptosis of macrophage.

Dexmedetomidine (DEX) displays a neuroprotective role in aged rats with isoflurane (ISO)-induced cognitive impairment through antioxidant, and anti-inflammatory, and anti-apoptotic effects. Therefore, the present study was performed to define the molecular mechanism of DEX on ISO-induced neurological impairment in aged rats in relation to the MEK1/ERK1/Nrf2/HO-1 axis. The study enrolled elderly patients undergoing ISO anesthesia. Patient cognitive function following treatment with DEX was evaluated using mini-mental state examination (MMSE). The results revealed that DEX supplementation of anesthesia contributed to higher MMSE scores in patients one week post treatment. Rat model of neurological impairment was also induced in 18-month-age Wistar rats by ISO, followed by DEX treatment. Based on the results of Morris water maze experiment, ELISA, and TUNEL and hematoxylin-eosin staining, in vivo experiments confirmed that DEX could reduce the oxidative stress and neurological damage induced by ISO in rats. DEX activated the nuclear factor erythroid 2-related factor (Nrf2)/Heme Oxygenase 1 (HO-1) pathway. DEX upregulated the expression of Nrf2 and HO-1 by activating the MEK1/ERK1 pathway, whereby attenuating the ISO-caused oxidative stress and neurological damage in rats. Collectively, DEX suppresses the ISO-induced neurological impairment in the aged rats by promoting HO-1 through activation of the MEK1/ERK1/Nrf2 axis.

OBJECTIVE: To update the current characteristics about the scope and quality of mixed methods research (MMR) in complementary and alternative medicine (CAM) after nearly 10 years. METHODS: A 5-stage approach for conducting a scoping review was adopted. Articles published on the top 10 journals in CAM with the highest impact factor in 2020 were screened for MMR. Information of included articles were extracted, and then synthesized to illustrate the current state. Methodological quality was evaluated according to the Mixed Method Appraisal Tool (MMAT) 2018 version. RESULTS: A total of 55 (55/2991, 2%) articles using mixed methods were retrieved, including 17 medical studies and 38 ethnobotanical studies. We performed an in-depth analysis on the 17 medical studies, which studied cancer, stress, pain, fatigue, exercises, mindfulness intervention, herbal medicine use, art and acupuncture. Thirteen pilot studies applied MMR to evaluate the feasibility of interventions or programs (13/17, 76%); phenomenology was inferred as the most common philosophical assumptions (13/17, 76%); the most applied type of MMR was convergent design (16/17, 94%); integration often took place at integration (12/17, 71%). Among the 16 eligible studies for quality appraisal, majority were rated as good (14/16, 88%), whereas two studies were rated as poorly described. Primarily, a poor rating was due to incomplete reporting of data analysis and citations in qualitative components; lack of confounder controlling and the sampling strategy in quantitative components; poor description of integration and justification for mixed methods. Comparing with the previous review, fewer MMR were published in 2020 in CAM, but the proportion of studies that clearly reported MMR has increased by 4 times (4%â15%). CONCLUSION: CAM researchers need to realize the benefits that MMR can have on conducting further health care research. Our findings highlight that applying MMR will be helpful to understand the complex dynamics and interdisciplinary nature of complex intervention. In addition, addressing a standardized reporting criteria for MMR is recommended.

Slow development has been shown to be a general mechanism to restore the fertility of thermo-sensitive and photoperiod-sensitive genic male sterile (TGMS and PGMS) lines in Arabidopsis. rpg1 is a TGMS line defective in primexine, which is essential for pollen wall pattern formation. Here, we showed that RPG1-GFP was highly expressed in microsporocytes, microspores, and pollen grains but not in the tapetum in the complemented transgenic line, suggesting that microsporocytes are the main sporophytic cells for primexine formation. Further cytological observations showed that primexine formation in rpg1 was partially restored under slow growth conditions, leading to its fertility restoration. RPG2 is the homolog of RPG1 in Arabidopsis. We revealed that the fertility recovery of rpg1 rpg2 was significantly reduced compared with that of rpg1 under low temperature. The RPG2-GFP protein was also expressed in microsporocytes in the RPG2-GFP (WT) transgenic line. These results suggest that RPG2 plays a redundant role in rpg1 fertility restoration. rpg1 plants were male sterile at the early growth stage, while their fertility was partially restored at the late developmental stage. The fertility of the rpg1 lateral branches was also partially restored. Further growth analysis showed that slow growth at the late reproductive stage or on the lateral branches led to fertility restoration. This work reveals the importance of gene redundancy in fertility restoration for TGMS lines and provides further insight into pollen wall pattern formation.

Secondary injury following cortical stroke includes delayed gliosis and eventual neuronal loss in the thalamus. However, the effects of aging and the potential to ameliorate this gliosis with NMDA receptor (NMDAR) antagonism are not established. We used the permanent distal middle cerebral artery stroke model (pdMCAO) to examine secondary thalamic injury in young and aged mice. At 3 days post-stroke (PSD3), slight microgliosis (IBA-1) and astrogliosis (GFAP) was evident in thalamus, but no infarct. Gliosis increased dramatically through PSD14, at which point degenerating neurons were detected. Flow cytometry demonstrated a significant increase in CD11b+/CD45int microglia (MG) in the ipsilateral thalamus at PSD14. CCR2-RFP reporter mouse further demonstrated that influx of peripheral monocytes contributed to the MG/MÏ population. Aged mice demonstrated reduced microgliosis and astrogliosis compared with young mice. Interestingly, astrogliosis demonstrated glial scar-like characteristics at two years post-stroke, but not by 6 weeks. Lastly, treatment with memantine (NMDAR antagonist) at 4 and 24 h after stroke significantly reduced gliosis at PSD14. These findings expand our understanding of gliosis in the thalamus following cortical stroke and demonstrate age-dependency of this secondary injury. Additionally, these findings indicate that delayed treatment with memantine (an FDA approved drug) provides significant reduction in thalamic gliosis.

To systematically review the efficacy and safety of Naoxueshu Oral Liquid in treatment of hypertensive intracerebral hemorrhage, four Chinese databases, four English databases, clinical trials registration center(ClinicalTrials.gov) and Chinese clinical trial registry were retrieved. The retrieval time was from the establishment of each database to September 9, 2020. According to the set criteria, the randomized controlled trial(RCT) of Naoxueshu Oral Liquid combined with conventional Western medicine was selected. The "Cochrane bias risk assessment" tool was used to evaluate the quality of the included studies. RevMan 5.4.1 was used to conduct Meta-analysis of the included studies and GRADE system was used to evaluate the evidence quality of the outcome indicators. Eleven studies were finally included, with a total sample size of 1 221 cases, 612 cases in the treatment group and 609 cases in the control group. Meta-analysis showed that Naoxueshu Oral Liquid combined with conventional Western medicine had no significant difference compare with conventional Western medicine in reducing National Institute of health stroke scale(NIHSS) after 2 weeks of treatment for hypertensive intracerebral hemorrhage(MD=-1.59,95%CI[-3.46,0.29],P=0.10), but was superior to conventional Western medicine after 30 d of treatment(MD=-1.16,95%CI [-1.39,-0.94],P<0.000 01). Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine in improving Glasgow coma scale(MD=1.00,95%CI[0,2.00],P=0.05) and reducing the incidence of secondary brain insults(RR=0.38,95%CI[0.24,0.59],P<0.000 1), but there was no significant difference in increasing Barthel index(MD=1.00,95%CI[-0.30,2.30],P=0.13). In terms of effective rate, studies using Guideline for clinical trials of new patent Chinese medicines, NHISS or Glasgow outcome scale(GOS) had shown that Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine(RR_(Guideline for clinical trials of new patent Chinese medicines)=1.27,95%CI[1.10,1.46],P=0.001;RR_(NHISS)=1.26,95%CI[1.13,1.40],P<0.000 1;RR_(GOS)=1.54,95%CI[1.22,1.93],P=0.000 2). In reduction of hematoma volume, Naoxueshu Oral Liquid combined with conventional Western medicine was superior to conventional Western medicine after 2 and 4 weeks of treatment(MD_(2 week)=-2.31,95%CI[-3.12,-1.49],P<0.000 01;MD_(4 week)=-2.04,95%CI[-2.41,-1.68],P<0.000 01). GRADE system showed that the evidence level of the above outcome indicators was low and extremely low. In terms of adverse reactions, two of the included studies reported mild adverse reactions, and the rest of studies were not mentioned, so this study was not able to make a positive evaluation of the safety of Naoxueshu Oral Liquid. This study showed that compared with conventional Western medicine, combined Naoxueshu Oral Liquid may be better for hypertensive intracerebral hemorrhage. However, due to the high bias risk in the included studies, more large-sample and high-quality RCTs are still needed in the future.

The effect of oral or nasal feeding with Chinese patent medicine on hypertensive intracerebral hemorrhage was systematically evaluated by using the method of network Meta-analysis. Four Chinese databases(CNKI, VIP, Wanfang, CBM), three English databases(Medline, EMbase, Cochrane Library) and ClinicalTrials.gov were retrieved through computers. According to the inclusion criteria and exclusion criteria, randomized controlled trials(RCTs) of Chinese patent medicine combined with Western medicine in the treatment of hypertensive intracerebral hemorrhage were screened out according to the inclusion criteria and exclusion criteria. The Cochrane bias risk assessment tool was used to evaluate the quality of the included studies, and Stata 16.0 software was used to analyze the outcome indicators. A total of 3 888 literatures were retrieved, and 30 studies involving 6 kinds of Chinese patent medicines were finally included. The total sample size was 2 758 cases, including 1 401 cases in the treatment group and 1 357 cases in the control group. According to the results of network Meta-analysis,(1)in terms of improving the degree of nerve function defect, the order of Chinese patent medicines was conventional Western medicine combined with Xiaoyukang Capsules>combined with Tongxinluo Capsules>combined with Naoxuekang Oral Liquid>combined with Naoxueshu Oral Liquid>combined with Angong Niuhuang Pills>conventional Western medicine;(2)in terms of reducing the amount of residual cerebral hematoma, the order of Chinese patent medicines was conventional Western medicine combined with Naoxueshu Oral Liquid>combined Xiaoyukang Capsules>combined Naoxuekang Oral Liquid>conventional Western medicine;(3)in terms of improving ability of daily living, the order of Chinese patent medicines was conventional Western medicine combined with Shenzhi Huoxue Capsules>combined with Angong Niuhuang Pills>combined with Naoxueshu Oral Liquid>conventional Western medicine;(4)in terms of improving total effective rate, the order of Chinese patent medicines was conventional Western medicine combined with Naoxueshu Oral Liquid>combined with Xiaoyukang Capsules>combined with Angong Niuhuang Pills=combined with Naoxuekang Oral Liquid>combined Tongxinluo Capsules>conventional Western medicine treatment. The results showed that in addition to conventional Western medicine therapy, the combined use with Chinese patent medicine can improve the clinical efficacy in the treatment of hypertensive intracerebral hemorrhage. However, due to the differences in the number and quality of various Chinese patent medicines included in the studies, and the lack of direct comparison of Chinese patent medicines, the ranking results still need to be verified by multi center, large-sample-size randomized double-blind trials in the future, so as to provide more reliable evidence support for clinical drug use.

The study aims to analyze the outcome indicators of randomized controlled trial(RCT) of traditional Chinese medicine(TCM) in the treatment of hypertensive intracerebral hemorrhage(HICH) in recent three years, and thus provide suggestions for the future studies in this field. Four English databases, four Chinese databases and two online registration websites of clinical trials were searched. The RCTs published between January 2018 and September 2020 were screened. The risk of bias was assessed and outcome measures were classified. A total of 151 839 articles were retrieved, of which 44 RCTs were included for analysis after screening. The outcome measures of the included RCTs were classified into 7 categories, among which the symptoms/signs category showed the highest reporting rate. National Institute of Health stroke scale(72.73%) was the most frequently reported outcome indicator, while the vo-lume of intracerebral hemorrhage determined by computerized tomography(36.36%) was the most frequently reported lab test outcome. Most studies collect the outcomes at the end of treatment, while 9 studies reported long-term outcomes 3 months or more after onset. Compared with those of international clinical trials, the application of some of the outcomes was reasonable, focusing on patients' symptoms, quality of life and objective outcomes. However, there were still several problems: unclear primary and secondary outcome measures, insufficient attention to long-term prognosis, insufficient attention to social function, few TCM outcomes, lack of measurement blindness and the use of unreasonable composite outcomes. It is recommended that researchers should rationally design the outcome indicators of clinical trials and develop the core outcome set.

To overview of systematic reviews/Meta-analysis of Xingnaojing Injection(XNJ) in the treatment of intracerebral hemorrhage(ICH). The systematic reviews concerning XNJ in the treatment of ICH were retrieved from four Chinese databases, four English databases, Chinese Clinical Trial Registry and ClinicalTrail.gov, with the retrieval time set from their inception to September 2020. Following the independent screening and data extraction by two researchers, a measurement tool to assess systematic evaluation 2(AMSTAR 2) and grades of recommendation, assessment, development and evaluation(GRADE) system were used to evaluate the metho-dological, reporting and evidence qualities of the 10 included systematic reviews. The results showed that XNJ was superior to the wes-tern medicine or conventional treatment in improving the effective rate and National Institutes of Health stroke scale(NIHSS) score, Barthel index(BI), and Glasgow coma scale(GCS) score and Chinese stroke scale(CSS) score, and reducing the mortality and cerebral hematoma volume, without inducing obvious adverse reactions. In general, the methodological, reporting and evidence qualities of the 10 included systematic reviews were poor. The AMSTAR 2 scores showed that key items No. 2 and No. 16 failed to meet the stan-dard, resulting in poor methodological quality. There was only one outcome indicator graded by GRADE as intermediate quality, 43% indicators as low quality, 42% indicators as extremely low quality, and none as high quality. These available evidences have suggested that the methodological, reporting and evidence qualities of the systematic evaluation concerning XNJ for the treatment of ICH need to be improved. Most evidences support that XNJ was better than the western medicine or conventional treatment in the treatment of ICH, but the methodological quality and the reliability of outcome indicators in relevant systematic review were low. More high-quality studies are still required for further verification.

To systematically review the efficacy and safety of acupuncture combined with minimally invasive surgery or basic the-rapy in treating hypertensive intracerebral hemorrhage(HICH) patients compared with minimally invasive surgery or basic treatment. In this study, the four Chinese databases, the four English databases, Chinese Clinical Trial Registry and ClinicalTrail.gov, all above were systematically and comprehensively retrieved from the time of database establishment to September 10, 2020. Rando-mized controlled trials(RCTs) were screened out according to inclusion criteria and exclusion criteria established in advanced. The methodological quality of included studies was evaluated by the tool named "Cochrane bias risk assessment 6.1". Meta-analysis of the included studies was performed using RevMan 5.4, and the quality of outcome indicators was evaluated by the GRADE system. Finally, 17 studies were included, involving 1 852 patients with HICH, and the overall quality of the included studies was not high. According to Meta-analysis,(1)CSS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-3.50,95%CI[-4.39,-2.61],P<0.000 01);(2)NIHSS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-4.78,95%CI[-5.55,-4.00],P<0.000 01);(3)the cerebral hematoma volume of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=-4.44,95%CI[-5.83,-3.04],P<0.000 01);(4)ADL score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=20.81,95%CI[17.25,24.37],P<0.000 01);(5)the GCS score of the group of acupuncture combined with minimally invasive surgery or basic therapy was superior to the group of minimally invasive surgery or basic therapy(MD=2.41,95%CI[1.90,2.91],P<0.000 01). The GRADE system showed an extremely low level of evidence for the above outcome indicators. Adverse reactions were mentioned only in two literatures, with no adverse reactions reported. The available evidence showed that acupuncture combined with minimally invasive surgery or basic therapy had a certain efficacy in patients of HICH compared with minimally invasive surgery or basic therapy. However, due to the high risk of bias in the included studies, its true efficacy needs to be verified by more high-quality studies in the future.

The present clinical practice guideline was written by experts organized by the special group of key projects in the 13 th five-year plan period of the China Academy of Chinese Medical Sciences based on the standards and procedures of World Health Orga-nization Handbook for Guideline Development, with "evidence-based, consensus-based, and experience-based principle" as a guide. On the basis of practice in traditional Chinese medicine(TCM) and clinical research for migraine, following the idea and method of evidence-based medicine, as well as the expert experience, the current best evidence and patients' values, the internationally recognized evidence quality evaluation methods and recommendation grading system were combined with the prescription record of classical TCM, TCM expert experience, and modern clinical research evidences. The acupuncture therapy, classic prescriptions and Chinese patent medicines used in the treatment of migraine in acute stage and preventive treatment were summarized to obtain five classic prescriptions(Chuanxiong Chatiao Powder, Chuanxiong Dingtong Yin, Sanpian Decoction, Xuefu Zhuyu Decoction, and Tongqiao Huoxue Decoction), and four Chinese patent medicines(Zhengtian Pills, Toutongning Capsules, Tongtian Oral Liquid, and Yangxue Qingnao Granules/Pills), and the common problems in their clinical application were analyzed. The purpose of this guideline is to standardize the treatment of migraine with TCM, reduce the frequency and severity of migraine attacks, and improve the patients' quality of life. It provides the clinical basis for the TCM treatment of migraine, and ensures the safety, effectiveness, practicability and scientificity of the treatment, so as to promote the TCM treatment of migraine. Due to the influence of region, nationality, race and other factors of the users, the detailed implementation of the guideline should be determined according to the actual situation.

To systemically assess the clinical efficacy of oral Chinese patent medicine for migraine by using network Meta-analysis. Four Chinese databases(CNKI, VIP, WanFang, CBM), three English databases(Medline, EMbase, Cochrane Library) and ClinicalTrials.gov were systematically and comprehensively retrieved from the establishment of each database to April 24, 2020. Rando-mized controlled trial(RCT) on oral Chinese patent medicine combined with Flunarizine for migraine were screened out according to inclusion criteria and exclusion criteria. Literature screening and data extraction were conducted independently by 2 researchers. The included studies were evaluated with the Cochrane bias risk assessment tool. Data analysis was conducted by using Stata 16.0 software. Finally, a total of 52 RCTs were included, involving 11 kinds of oral Chinese patent medicines. The results of the network Meta-analysis showed that in terms of headache frequency, the order of efficacy was: Flunarizine combined with Tongtian Oral Liquid>combined with Zhengtian Pills>combined with Toutongning Capsules>combined with Yangxue Qingnao Granules>combined with Tianshu Capsules>combined with Xuefu Zhuyu Capsules>combined with Danzhen Toutong Capsules>combined with Chuanxiong Qingnao Granules>combined with Songling Xuemaikang Capsules. In terms of headache intensity, the order of efficacy was: Flunarizine combined with Tongtian Oral Liquid>combined with Zhengtian Pills>combined with Danzhen Toutong Capsules>combined with Tianshu Capsules>combined with Toutongning Capsules>combined with Chuanxiong Qingnao Granules>combined with Yuntongding Capsules>combined with Yang-xue Qingnao Granules>combined with Danqi Soft Capsules. In terms of headache lasting time, the order of efficacy was: Flunarizine combined with Tongtian Oral Liquid>combined with Yangxue Qingnao Granules>combined with Toutongning Capsules>combined with Zhengtian Pills>combined with Danzhen Toutong Capsules>combined with Tianshu Capsules>combined with Xuefu Zhuyu Capsules>combined with Yuntongding Capsules>combined with Chuanxiong Qingnao Granules>combined with Songling Xuemaikang Capsules. The results showed that oral Chinese patent medicines combined with Flunarizine were effective in improving the clinical efficacy for migraine. Due to the differences in the number and quality of studies included in studies of different Chinese patent medicines, and the lack of direct comparison of Chinese patent medicines, the results of the above order of Chinese patent medicines need to be demonstrated in future multi-center, large-sample, and double-blind randomized trial.

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.
