Study on medication law of TCM compounds with national patents for treatment of vascular dementia / 国际中医中药杂志

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.

Anti-tumor mechanism study on saffron by network pharmacology and reverse molecular docking / 药学实践杂志

Objective To explore the anti-tumor mechanism of saffron (Crocus sativus L.) by network pharmacology and reverse molecular docking techniques. Methods The main chemical components of saffron were obtained by searching published literature and TCMSP database. The potential targets of these components were predicted using PharmMapper server. The corresponding target genes were identified from UniProt database. The underlying anti-tumor targets of saffron were obtained by mapping the disease genes of cancer or tumor with GeneCards, OMIM and TTD databases. Cytoscape software was used to construct the action target network of saffron active components. The protein-protein interaction analysis was performed by String database, and the GO function and KEGG pathway enrichment analysis were performed by Metascape platform. Finally, molecular docking was performed to evaluate the binding of main components with their potential targets. Results A total of 9 active ingredients in saffron including quercetin, kaempferol, isorhamnetin, picrocrocin and crocin I, were identified, which might act on 37 key targets including AKT1, CCND1, MMP9, EGFR, TP53, involved in P53, TNF and other signaling pathways. Molecular docking indicated modest binding potency through hydrogen bonding, and hydrophobic interactions. Conclusion The anti-tumor effect of saffron was evaluated via the network of components-targets-pathways, which might provide a foundation for further research.

Childhood maltreatment on psychiatric symptoms and drug efficacy in patients with schizophrenia / 西安交通大学学报(医学版)

【Objective】 To explore the effect of childhood maltreatment on clinical symptoms and early efficacy of antipsychotics in patients with schizophrenia. 【Methods】 Totally 73 schizophrenic patients were divided into mild maltreatment group(n=42) and severe maltreatment group(n=31) according to the Child Trauma Questionnaire(CTQ). The Positive and Negative Symptom Scale(PANSS) and Clinical Global Impression(CGI) were measured and compared between the two groups at baseline and 3 weeks after antipsychotic treatment to analyze the correlation between child maltreatment experience and mental symptoms and the response to early treatment of antipsychotics. 【Results】 PANSS positive factor score(P=0.026) and cognitive deficit factor score (P=0.042) were significantly higher in severe abuse group than in mild abuse group. The positive factor was significantly positively correlated with emotional abuse factor in CTQ score(r=0.257, P=0.028), and the cognitive deficit factor was significantly positively correlated with emotional neglect factor(r=0.283, P=0.015). After antipsychotic treatment, the reduction rate of PANSS negative factor in severe abuse group was significantly lower than that in mild abuse group(P=0.035), and had the highest correlation with CTQ physical abuse factor(r=-0.302, P=0.011). 【Conclusion】 The severity of childhood maltreatment experienced by schizophrenic patients is more related to positive symptoms and cognitive deficits, and more childhood maltreatment experience will affect the improvement of negative symptoms by antipsychotics, suggesting a poor prognosis.

Advances in histone epigenetic enzyme inhibitors based on proteomics / 药学学报

As an important component of nucleosomes on the chromatin of eukaryotic cells, histones play an important role in the development and progression of tumour diseases by regulating epigenetic post-translational modifications such as acetylation and methylation. In addition, development of inhibitors targeting methyltransferase and deacetylase provides novel therapeutic strategies for cancer treatment. Mass spectrometry-based proteomics can reveal the global changes of histone modifications under the action of drugs during disease progression, which in turn provides important support for revealing drug action mechanism, drug resistance mechanism, and investigating novel drug combination strategies. This article focuses on the progress and status of proteomic research on a variety of histone modifying enzyme inhibitors, including methyltransferase inhibitors and histone deacetylase inhibitors, which will help to understand the current and further utilization of proteomics in studying histone modifications.

Relationship between mechanism underlying antidepressant effect of S-ketamine and hippocampal GABA BR in mice / 中华麻醉学杂志

Objective:To evaluate the relationship between the mechanism underlying the antidepressant effect of S-ketamine and hippocampal gamma-aminobutyric acid B receptor (GABA BR) in mice. Methods:A total of 54 male C57BL/6(B6) mice, aged 8 weeks, weighing 25-30 g, were used in this study. Forty mice were selected to develop the depression model by chronic social defeat stress. Twenty-six depression-susceptible mice were screened out by social avoidance test at day 11 after developing the model and divided into 2 groups ( n=13 each) by a random number table method: depression-susceptible group (Sus group) and depression-susceptible + S-ketamine group (Sus + S-ket group). The remaining 14 mice served as control group (C group). Starting from day 12 after developing the model, S-ketamine 10 mg/kg was intraperitoneally injected every day for 3 consecutive days in Sus+ S-ket group, while the equal volume of normal saline was given instead in C group and Sus group. The open field test was performed at 1 h after the last administration, and the total distance of movement was recorded. The forced swimming test was performed at 1 day after the open field test, and the immobile time was recorded. The sucrose preference test was performed to calculate the proportion of sucrose consumption at 1 day after the forced swimming test. One hour after the end of behavioral test, mice were sacrificed, and the hippocampal tissues were removed. Western blot was used to detect the expression of GABA BR1, GABA BR2, mammalian target of rapamycin (mTOR), phosphorylated mTOR (p-mTOR), brain-derived neurotrophic factor (BDNF), tyrosine kinase receptor B (TrkB), phosphorylated TrkB (p-TrkB), glutamate receptor 1 (GluR1) and postsynaptic dense protein 95 (PSD95). The p-mTOR/mTOR ratio and p-TrkB/TrkB ratio were calculated. The fluorescence intensity of BDNF in hippocampal CA1 region was detected by immunofluorescence. The number of dendritic spines in hippocampal CA1 region was measured by Golgi staining. Results:In the open field test, no statistically significant difference in the total distance was detected among the three groups ( P>0.05). Compared with C group, the immobile time in the forced swimming test was significantly prolonged, the proportion of sucrose consumption was decreased, the expression of hippocampal GABA BR1, GABA BR2, BDNF, GluR1 and PSD95 was down-regulated, and the ratios of p-mTOR/mTOR and p-TrkB/TrkB were decreased, the fluorescence intensity of BDNF and total number of dendritic spines in the hippocampal CA1 region were decreased in Sus group ( P<0.05), and no significant change was found in the parameters mentioned above in Sus+ S-ket group ( P>0.05). Compared with Sus group, the immobile time in the forced swimming test was significantly shortened, the proportion of sucrose consumption was increased, the expression of hippocampal GABA BR1, GABA BR2, BDNF, GluR1 and PSD95 was up-regulated, the ratios of p-mTOR/mTOR and p-TrkB/TrkB were increased, and the fluorescence intensity of BDNF and total number of dendritic spines in the hippocampal CA1 region were increased in Sus+ S-ket group ( P<0.05). Conclusions:The mechanism underlying the antidepressant effect of S-ketamine may be related to up-regulation of hippocampal GABA BR expression, activation of mTOR-BDNF signaling pathway, and improvement in synaptic plasticity in mice.

Mechanism of paeoniflorin inhibiting apoptosis of hippocampal neurons of rats induced by lead acetate / 中华劳动卫生职业病杂志

Objective: To investigate the effect and underlying mechanism of paeoniflorin on hippocampal neuron apoptosis induced by lead acetate. Methods: In September 2020, primary hippocampal neuronal cells were isolated and cultured from fetal rats, and identified using cellular immunofluorescent. MTT assay was used to measure the cell viability to determine the concentration and time of lead acetate-induced hippocampal neuron apoptosis. MTT was also used to evaluate the effect of paeoniflorin concentration on the apoptosis of hippocampal neurons induced by lead acetate. According to the results, different concentrations of paeoniflorin were selected to intervene hippocampal neuron cells, after 24 h, lead acetate was added to the cells, meanwhile, blank and model groups were set up, the content of reactive oxygen species (ROS) , superoxide dismutase (SOD) , lactate dehydrogenase (LDH) , malondialdehyde (MDA) and Caspase-3 were measured. Extracellular signal regulated kinase (ERK) , phosphorylated ERK (p-ERK) , p38 mitogen -activated protein kinases (p38MAPK) , phosphorylated p38MAPK (p-p38MAPK) , c-Jun N-terminal kinase (JNK) and phosphorylated JNK (p-JNK) protein expression in hippocampal neuronal cells were determined by Western blotting. Results: The isolated and cultured hippocampal neurons were identified by immunofluorescence chemical staining and then treated with lead acetate, MTT results showed that lead acetate had the best toxicity effect when treated for 24 h at a concentration of 25 μmol/L. Paeoniflorin showed no cytotoxic effect on hippocampal neuronal cells when the concentrations below 80 μmol/L. Compared with the model group, the activity of hippocampal neuronal cells was significantly increased after treating with 20, 40 or 80 μmol/L paeoniflorin (P<0.05) . Compared with the blank group, the ROS activity, LDH release level, MDA content and caspase-3 content were significantly increased (P<0.01) , and the SOD activity was significantly decreased (P< 0.01) in the hippocampal neuronal cells of the model group. Compared with the model group, the ROS activity, LDH release level, MDA content and caspase-3 content were obviously decreased (P<0.05) , SOD activity was significantly increased (P <0.01) after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin. Relative to the model group, the ratio of p-ERK/ERK were significantly up-regulated (P<0.01) , while the ratios of p-p38MAPK/p38MAPK and p-JNK/JNK were significantly down-regulated after hippocampal neuronal cells were treated with 40 or 80 μmol/L paeoniflorin (P<0.05) . Conclusion: Paeoniflorin may down-regulate the expression of p-p38MAPK and p-JNK protein, up-regulate the expression of p-ERK protein, and inhibit the apoptosis of hippocampal neurons induced by lead acetate through the MAPK signaling pathway.

Systematic review and Meta-analysis of efficacy and safety of acupuncture therapy on hypertensive intracerebral hemorrhage / 中国中药杂志

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.

Overview of systematic reviews/Meta-analysis of Xingnaojing Injection in treatment of intracerebral hemorrhage / 中国中药杂志

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.

Situation analysis of outcome indicators of randomized controlled trials of traditional Chinese medicine in treatment of hypertensive intracerebral hemorrhage in recent three years / 中国中药杂志

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.

Genetic diversity and genetic structures of original plants of Viticis Fructus:an SSR markers-based analysis / 中国中药杂志

The present study aimed to provide the protection strategies for wild germplasm resources of original plants of Viticis Fructus and a theoretical basis for the sustainable use of Viticis Fructus. The genetic diversity and genetic structures of the 232 indivi-duals in 19 populations of Vitex rotundifolia and V. trifolia were analyzed by eight SSR markers with tools such as Popgene32, GenAlex 6.502, and STRUCTURE. Bottleneck effect was detected for the population with more than 10 individuals. The results indicated that 42 and 26 alleles were detected from the populations of V. rotundifolia and V. trifolia, respectively, with average expected heterozygo-sities of 0.448 6 and 0.583 9, which are indicative of low genetic diversity. AMOVA revealed the obvious genetic variation of V. rotundifolia and V. trifolia within population(84.43%, P<0.01; 60.37%, P<0.01). Furthermore, in eight SSR loci, six from V. rotundifolia populations and two from V. trifolia populations failed to meet Hardy-Weinberg equilibrium expectations(P<0.05), which confirmed that the populations experienced bottleneck effect. As assessed by Mantel test, geographical distance posed slight impacts on the genetic variation between the populations of V. rotundifolia and V. trifolia. Principal component analysis(PCA) and STRUCTURE analysis demonstrated evident introgression of genes among various populations. The original plants of Viticis Fructus were confirmed low in genetic diversity and genetic differentiation level. Therefore, the protection of wild resources of original plants of Viticis Fructus should be strengthened to ensure its sustainable use.

Network Meta-analysis of oral or nasal feeding with Chinese patent medicine in treatment of hypertensive intracerebral hemorrhage / 中国中药杂志

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.

Systematic review and Meta-analysis on efficacy and safety of Naoxueshu Oral Liquid in treatment of hypertensive intracerebral hemorrhage / 中国中药杂志

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 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.

Systematic review and Meta-analysis on randomized controlled trial of efficacy and safety for acupuncture versus Flunarizine in treatment of migraine / 中国中药杂志

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.

Network Meta-analysis of oral Chinese patent medicine in treatment of migraine / 中国中药杂志

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.

Expression and clinical significance of serum ubiquitin in esophageal squamous cell carcinoma / 医学研究生学报

Objective　Ubiquitin-proteasome system (UPS) plays a central role in the development of esophageal cancer. However, As the executor of UPS, the expression and clinical significance of detection of serum ubiquitin (UB) in Esophageal Squamous Cell Carcinoma(ESCC) patients have not been fully elucidated. The aim of this study was to investigate the expression and diagnostic value of serum ubiquitin (UB) in ESCC.　Methods　A total of eighty-eight ESCC patients and forty healthy controls from February 2018 to May 2019 at the Affiliated Jiangyin Hospital of Nantong University were enrolled. Serum UB was measured by ELISA, and serum squamous cell carcinoma antigen (SCC) and carcinoembryonic antigen (CEA) were determined by chemiluminescence method. The ROC curve was used to analyze the diagnostic value of each indicator. Besides, the correlation between serum UB and clinicopathological features of ESCC were analyzed.　Results　The level of serum UB in ESCC group was significantly higher than that in the control group[(41.96±3.273)ng/ml vs (80.86±7.993)ng/ml, P<0.05]. The level of serum UB in ESCC patients was related to lymphatic metastasis and tumor stage (P<0.05). The sensitivity of UB, SCC, CEA and the three combined diagnosis of ESCC were 65.9%, 52.3%, 51.1%, and 76.1%, respectively. The AUC under the ROC curve were 0.690, 0.677, 0.635, and 0.795, respectively.　Conclusion　Serum UB is highly expressed in ESCC and is closely related to tumor progression. Combined with SCC and CEA, UB can improve the sensitivity of diagnosis of ESCC and can be used as an effective serological screening biomarker.
