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
Acetaminophen (APAP) overdose is a major cause of liver injury. Neural precursor cell expressed developmentally downregulated 4-1 (NEDD4-1) is an E3 ubiquitin ligase that has been implicated in the pathogenesis of numerous liver diseases; however, its role in APAP-induced liver injury (AILI) is unclear. Thus, this study aimed to investigate the role of NEDD4-1 in the pathogenesis of AILI. We found that NEDD4-1 was dramatically downregulated in response to APAP treatment in mouse livers and isolated mouse hepatocytes. Hepatocyte-specific NEDD4-1 knockout exacerbated APAP-induced mitochondrial damage and the resultant hepatocyte necrosis and liver injury, while hepatocyte-specific NEDD4-1 overexpression mitigated these pathological events both in vivo and in vitro. Additionally, hepatocyte NEDD4-1 deficiency led to marked accumulation of voltage-dependent anion channel 1 (VDAC1) and increased VDAC1 oligomerization. Furthermore, VDAC1 knockdown alleviated AILI and weakened the exacerbation of AILI caused by hepatocyte NEDD4-1 deficiency. Mechanistically, NEDD4-1 was found to interact with the PPTY motif of VDAC1 through its WW domain and regulate K48-linked ubiquitination and degradation of VDAC1. Our present study indicates that NEDD4-1 is a suppressor of AILI and functions by regulating the degradation of VDAC1.
ABSTRACT
Objective:To analyze the changing trend of the incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019, and predict the future development trend of liver cancer.Methods:The descriptive epidemiologic method was conducted. Based on the Global Burden of Disease data from the Institute for Health Metrics and Evaluation at the University of Washington, the crude incidence rate and total number, crude mortality rate and total number, age- and sex-specific incidence rate and number, age- and sex-specific mortality rate and number of liver cancer in the Chinese population from 1990 to 2019 were collected. The age-standardized rate was calculated using the year 2000 China's standard population. Observation indicators: (1) the incidence and mortality of liver cancer in the Chinese population from 1990 to 2019; (2) changing trend of the age-standardized incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019; (3) prediction of the incidence and mortality of liver cancer in the Chinese population during 2020-2044. Count data were described as absolute numbers, percentages and ratios. The Joinpoint V.4.9.0.0 software was used to calculate the annual percent change (APC), average annual percent change (AAPC) and its 95% confidence interval ( CI) of age-standardized incidence and mortality rates of liver cancer in different time periods. The age-period-cohort model in the Nordpred package of R software (V.4.1.1) was used to predict the incidence and mortality of liver cancer in the Chinese population during 2020-2044. Results:(1) The incidence and mortality of liver cancer in the Chinese population from 1990 to 2019: the crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese population decreased from 20.01/100,000 and 24.31/100,000 in 1990 to 14.80/100,000 and 9.71/100,000 in 2019, respectively. The crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese male popula-tion decreased from 27.88/100,000 and 34.76/100,000 in 1990 to 22.05/100,000 and 15.22/100,000 in 2019, respectively. The crude incidence rate and the age-standardized incidence rate of liver cancer in the Chinese female population decreased from 11.63/100,000 and 13.51/100,000 in 1990 to 7.26/100,000 and 4.29/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese population decreased from 19.64/100,000 and 23.97/100,000 in 1990 to 13.20/100,000 and 8.44/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese male population decreased from 27.03/100,000 and 34.10/100,000 in 1990 to 19.18/100,000 and 13.03/100,000 in 2019, respectively. The crude mortality rate and the age-standardized mortality rate of liver cancer in the Chinese female population decreased from 11.78/100,000 and 13.64/100,000 in 1990 to 6.98/100,000 and 3.97/100,000 in 2019, respectively. (2) Changing trend of the age-standardized incidence and mortality rates of liver cancer in the Chinese population from 1990 to 2019: the trend of age-standardized incidence rate of liver cancer in the Chinese population could be divided into 5 periods, namely year 1990 to 1996, year 1996 to 2001, year 2001 to 2005, year 2005 to 2010 and year 2010 to 2019. In these 5 periods, the APC of age-standardized incidence rate changed from 1.27%(95% CI as 0.81% to 1.73%, P<0.001) to 1.12%(95% CI as 0.91% to 1.33%, P<0.001) of the total Chinese population, from 1.68%(95% CI as 1.19% to 2.17%, P<0.001) to 1.65%(95% CI as 1.42% to 1.87%, P<0.001) of the Chinese male population and from 0.21%(95% CI as -0.32 % to 0.75%, P=0.406) to -0.14%(95% CI as -0.40% to 0.11%, P=0.241) of the Chinese female population, respectively. The trend of age-standardized mortality rate of liver cancer in the Chinese population could be divided into 5 periods, namely year 1990 to 1996, year 1996 to 2000, year 2000 to 2005, year 2005 to 2012 and year 2012 to 2019. In these 5 periods, the APC of age-standardized mortality rate changed from 1.47%(95% CI as 0.74% to 2.20%, P=0.001) to 1.34%(95% CI as 0.78% to 1.90%, P<0.001) of the total Chinese population, from 1.96%(95% CI as 1.18% to 2.75%, P<0.001) to 1.79%(95% CI as 1.18% to 2.41%, P<0.001) of the Chinese male population and from 0.14%(95% CI as -0.54% to 0.82%, P=0.670 ) to 0.48%(95% CI as 0.02% to 0.93%, P=0.041) of the Chinese female population, respectively. From 1990 to 2019, the AAPC of age-standardized incidence and age-standardized mortality rates of liver cancer were -3.22%(95% CI as -3.41% to -3.03%) and -3.51%(95% CI as -3.82% to -3.19%) in the Chinese population, -2.90%(95% CI as -3.10% to -2.71%) and -3.22%(95% CI as -3.57% to -2.88%) in the Chinese male population, -3.96%(95% CI as -4.17% to -3.76%) and -4.13%(95% CI as -4.43% to -3.82%) in the Chinese female population, respectively. (3) Prediction of the incidence and mortality of liver cancer in the Chinese population during 2020-2044: the age-standardized incidence rate of liver cancer would decrease from 9.51/100,000 in 2015-2019 to 5.78/100,000 in 2040-2044 in the Chinese population, from 14.84/100,000 in 2015-2019 to 9.75/100,000 in 2040-2044 in the Chinese male population and from 4.28/100,000 in 2015-2019 to 1.88/100,000 in 2040-2044 in the Chinese female population, respectively. The age-standardized mortality rate of liver cancer would decrease from 8.40/100,000 in 2015-2019 to 4.62/100,000 in 2040-2044 in the Chinese population, from 12.91/100,000 in 2015-2019 to 7.59/100,000 in 2040-2044 in the Chinese male population and from 4.01/100,000 in 2015-2019 to 1.70/100,000 in 2040-2044 in the Chinese female population, respectively. The incidence number and mortality number of liver cancer from 2020 to 2044 would remain stable at around 160,000 per year and 140,000 per year in the Chinese population, 128,500 per year and 109,000 per year in the Chinese male population, 36,000 per year and 34,900 per year in the Chinese female population, respectively. Conclusion:The incidence and mortality rates of liver cancer in the Chinese popula-tion show a significant downward trend from 1990 to 2019, and the incidence number and mortality number of liver cancer in the Chinese population will remain stable above 100,000 during 2020-2044.
ABSTRACT
Antibiotics are a category of chemical compounds used to treat bacterial infections and are widely applied in cultivation,animal husbandry,aquaculture,and pharmacy.Currently,residual antibiotics and their metabolites pose a potential risk of allergic reactions,bacterial resistance,and increased cancer incidence.Residual antibiotics and the resulting bacterial antibiotic resistance have been recognized as a global challenge that has attracted increasing attention.Therefore,monitoring antibiotics is a critical way to limit the ecological risks from antibiotic pollution.Accordingly,it is desirable to devise new analytical platforms to achieve efficient antibiotic detection with excellent sensitivity and specificity.Quantum dots(QDs)are regarded as an ideal material for use in the development of antibiotic detection biosensors.In this review,we characterize different types of QDs,such as silicon,chalcogenide,carbon,and other doped QDs,and summarize the trends in QD-based antibiotic detection.QD-based sensing applications are classified according to their recognition strategies,including molecularly imprinted polymers(MIPs),aptamers,and immunosensors.We discuss the advantages of QD-derived antibiotic sensors,including low cost,good sensitivity,excellent stability,and fast response,and illustrate the current challenges in this field.
ABSTRACT
Objective To understand the situation of cancer screening of community residents and its association with the knowledge of cancer core knowledge, and to provide reference for the formulation of secondary cancer prevention measures. Methods A cross-sectional survey was conducted among 2 037 residents aged 18-79 who lived in Bao 'an District, Shenzhen. Multivariate Logistic regression analysis was used to investigate the relationship between core knowledge and cancer screening behavior after adjusting for age, gender, education, marriage, occupation and smoking. Results The cancer screening rate of community residents was 28.10%, and the screening rate of middle-aged and elderly people aged 40-79 was 33.50 %.The proportion of “not very well understanding”, “partial understanding” and “basic understanding” of the core knowledge of cancer were 43.91%, 42.33% and 13.76%, respectively, which was higher than that of the non-participants. Multivariate analysis showed that the women, the higher the level of education of college/university or above and the higher the level of knowledge of cancer prevention core knowledge, the higher the probability of participating in cancer screening was OR (95%CI ) : 2.40 (1.86-3.12), 1.65 (1.29-2.10), 1.38 (1.18 - 1.62), respectively. Conclusion The proportion of cancer screening in community residents needs to be improved, and the degree of core knowledge of cancer is closely related to cancer screening behavior. It is suggested to increase the publicity and education of the core knowledge of cancer, and at the same time, carry out the health education of secondary cancer prevention for the key population such as men and people with low education level, so as to improve the proportion of “early detection, early diagnosis and early treatment” of cancer.
ABSTRACT
Nonalcoholic fatty liver disease (NAFLD) is characterized by hepatic steatosis and insulin resistance and there are currently no approved drugs for its treatment. Hyperactivation of mTOR complex 1 (mTORC1) and subsequent impairment of the transcription factor EB (TFEB)-mediated autophagy-lysosomal pathway (ALP) are implicated in the development of NAFLD. Accordingly, agents that augment hepatic TFEB transcriptional activity may have therapeutic potential against NAFLD. The objective of this study was to investigate the effects of nuciferine, a major active component from lotus leaf, on NAFLD and its underlying mechanism of action. Here we show that nuciferine activated ALP and alleviated steatosis, insulin resistance in the livers of NAFLD mice and palmitic acid-challenged hepatocytes in a TFEB-dependent manner. Mechanistic investigation revealed that nuciferine interacts with the Ragulator subunit hepatitis B X-interacting protein and impairs the interaction of the Ragulator complex with Rag GTPases, thereby suppressing lysosomal localization and activity of mTORC1, which activates TFEB-mediated ALP and further ameliorates hepatic steatosis and insulin resistance. Our present results indicate that nuciferine may be a potential agent for treating NAFLD and that regulation of the mTORC1-TFEB-ALP axis could represent a novel pharmacological strategy to combat NAFLD.
ABSTRACT
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.

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.

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.

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.

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.

Methods Fluorescence immunoassay was used to detect G6PD activity in an initial screening. Children who were positive in the first screening were recalled for a second screening. Second screening positive children were recalled for G6PD gene testing. Results A total of 105 newborns were positive in the first screening, for a positive rate of 0.21%. A total of 93 cases were recalled, and the recall rate was 88.60%. There were 77 cases positive in the second screening, and the positive rate was 82.80%. A total of 65 patients were recalled, of which 49 neonates were diagnosed, 1 was normal, and 15 refused gene testing. The incidence rate was 0.10%. Conclusion The incidence of newborn G6PD deficiency in Huangshi area is relatively low, which is consistent with the disease distribution trend of “south high-north low”.
ABSTRACT
Objective::To compare the pharmacodynamic effects of pith-nodecayed and pith-decayed products of Scutellariae Radix on rats with large intestine damp-heat syndrome, and to demonstrate the scientificness of dividing Scutellariae Radix into pith-nodecayed and pith-decayed products as medicines by modern pharmacological test. Method::Rats were randomly divided into blank group, model group, low-and high-dose group of pith-nodecayed products (0.9, 3.6 g·kg-1), low-and high-dose group of pith-decayed products (0.9, 3.6 g·kg-1), Scutellariae Radix group (0.9 g·kg-1), compound berberine tablets group (positive drug group, 0.045 g·kg-1), and 8 rats in each group. Taking model rats with large intestine damp-heat syndrome, the body temperature, thymus index, spleen index, pathological sections of colon and ileum, inflammatory factors and Secretory immunoglobulin (SIg) A content were selected as indexes to evaluate the therapeutic effect of pith-nodecayed and pith-decayed products on large intestine damp-heat syndrome, and make comprehensive evaluation of the difference in efficacy between them. Partial least squares-discriminant analysis (PLS-DA) was employed to analyze the pharmacological indexes of these two products against large intestine damp-heat syndrome. Result::Pith-nodecayed and pith-decayed products of Scutellariae Radix with different doses could reduce the body temperature, thymus index, spleen index, contents of interleukin (IL)-2, IL-6, IL-1β in serum and SIgA content in intestinal mucosa, and most of them had significant differences (P<0.05, P<0.01). Compared with the isodose group of pith-decayed products, the effect of corresponding dose group of pith-nodecayed products was better, and most of them had significant differences (P<0.05, P<0.01). PLS-DA results indicated that there were significant differences in the pharmacological effects of pith-nodecayed and pith-decayed products, and they were clustered on one side, respectively. Conclusion::Both of pith-nodecayed and pith-decayed products of Scutellariae Radix have therapeutic effect on large intestine damp-heat syndrome with distinctly different strength of action, and pith-nodecayed products is superior to pith-decayed products, which verify the scientific nature of pith-nodecayed products was specializedly used to treat bowel disease in ancient times.

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.

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 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.

Setariae Fructus Germinatus (Guya) is a commonly used traditional Chinese medicine, which has been used for thousands of years. In ancient and modern books and works, the name is often confused because of its complicated relationship with the origin. In order to clarify the name and source of Guya, the authors examined the name, origin and processing history of Guya through consulting ancient Chinese herbal books, modern Chinese medicine monographs, calendar edition of Chinese Pharmacopoeia and the processing standards of various provinces, and found that different regions in China used Guya according to their local habits, resulting in the foreign body of the same name of Guya, lacking a unified standard. It is suggested that changing the name of Guya to Suya is more practical, and is conducive to the quality standard research and clinical accurate application of Guya.
ABSTRACT
Objective To understand the status of knowledge, attitude and practice on echinococcosis prevention and control and investigate their influencing factors among residents living in Seda County of Sichuan Province, so as to provide a scientific basis for the further implementation of health education interventions in the county. Methods A multi-stage stratified random sampling method was employed on September 2018. Ten townships were randomly sampled, and 2 to 3 administrative villages were randomly sampled from each township. Then, 20 to 40 households were randomly sampled from each village, and 1 to 2 villagers were investigated in each household. The knowledge, attitude and practice on echinococcosis prevention and control were investigated using a household questionnaire survey, and the factors affecting the qualification of echinococcosis prevention and control knowledge were identified using chi-square test and logistic regression analysis. Results A total of 760 questionnaires were assigned, and 748 effective questionnaires were recovered, with a recovery rate of 98.42%. The overall qualification rate of echinococcosis prevention and control knowledge was 56.42% (422/748) in residents living in Seda County, and the awareness of the question “How to get echinococcosis?” was only 48.40%. The proportion of subjects with a positive attitude towards echinococcosis prevention and control was 64.71% to 94.79%, and the rate of corrected echinococcosis prevention and control behaviors was 10.40% to 82.45%. Univariate analysis showed that factors affecting the qualification rate of echinococcosis prevention and control knowledge included gender, occupation, education level, frequency of echinococcosis screening and frequency of health education (all P < 0.05), and binary logistic regression analysis showed that women, herdsmen as the primary occupation, an education level of primary school and below, absence of echinococcosis screening and absence of health education were factors responsible for the unqualified awareness of echinococcosis prevention and control knowledge (all P < 0.05). Conclusions There is a low awareness rate of echinococcosis prevention and control knowledge and a low proportion of corrected echinococcosis prevention and control behaviors in residents living in Seda County, Sichuan Province. Multiple forms of health education activities pertaining to echinococcosis prevention and control are needed with adaptation to local circumstance, and implementation of appropriate behavioral interventions is recommended.
ABSTRACT
Objective Studying the differential expression of exosomal miRNAs between androgen-dependent prostate cancer cell and androgen-independent prostate cancer cell,in order to further elucidate the mechanism of androgen-independent prostate cancer and find new targets for its treatment.Methods Prostate cancer androgen-dependent LNCaP cell and prostate cancer androgen-independent LNCaP-AI + F cell (induced by androgen and flutamide) were selected as the study subjects.Illumina HiSeqTM 2500 was used to perform high-throughput sequencing between the two groups.The differentially expressed exosomal miRNAs was verified by quantitative real-time PCR(qRT-PCR).The difference was statistically significant by t-test.Results Through the analysis of high-throughput sequencing results,thirteen molecules were screened increased in extracellular exosomes of the androgen-independent cell,including miR-7-5p,let-7a-5p,miR-375,miR-423-3p,miR-378a-3p,and miR-92a-3p,etc.Among them,miR-7-5p was verified by quantitative real-time PCR to be up-regulated by 19.52-fold (t=9.857,P=0.001).Conclusion Differentially expressed exosomal miRNAs may predict the development of androgen-independent prostate cancer and may further regulate the development of androgen-independent prostate cancer.
ABSTRACT
Objective:To investigate the dryness effect of Atractylodes lancea and A. chinensis. Method:Sixty normal and healthy SD rats were randomly divided into 6 groups(10 in each group), including normal saline group, soybean oil group, low-dose(46.25 mg·kg-1·d-1) group and high-dose(500 mg·kg-1·d-1) group of A. lancea, low-dose(46.25 mg·kg-1·d-1) group and high-dose(500 mg·kg-1·d-1) group of A. chinensis, the dosing volume was 0.01 mL·g-1, and the drug was administered orally for 21 days. Taking average daily water intake, submandibular gland tissue, urine volume and expression of aquaporin 2(AQP2) in the kidney, and whole blood viscosity as the evaluation indexes, the dryness effect of long-term administration of equal doses of volatile oil from A. lancea and volatile oil from A. chinensis on rats was observed. Result:Compared with the soybean oil group, long-term administration of high doses of volatile oil from A. lancea and volatile oil from A. chinensis could significantly increase average daily water intake, urine volume and whole blood viscosity; decrease the expression of AQP2, and atrophy the acini of submandibular gland, but there was no significant difference between the two groups. Effects of volatile oil from A. lancea and A. chinensis with low dose on dryness of rats were not significant. Conclusion:There is no significant difference between the dryness effect of volatile oil from A. lancea and A. chinensis in the same dose. It is proved that the rationality of A. lancea and A. chinensis are universal in clinical practice, and this study provides experimental basis for rational use of Atractylodis Rhizoma.
