RESUMO

BACKGROUND: Ischemic stroke (IS) is a major cause of disability and mortality worldwide. Increasing evidence suggests a strong association between blood pressure, blood glucose, circulating lipids, and IS. Nonetheless, the genetic association of these 3 risk factors with IS remains elusive. METHODS: We screened genetic instruments related to blood pressure, blood glucose, and circulating lipids and paired them with IS genome-wide association study data to conduct Mendelian randomization analysis. Positive Mendelian randomization findings were then subjected to colocalization analysis. Subsequently, we utilized the Gene Expression Omnibus data set to perform differential expression analysis, aiming to identify differentially expressed associated genes. We determined the importance scores of these differentially expressed associated genes through 4 machine learning models and constructed a nomogram based on these findings. RESULTS: The combined results of the Mendelian randomization analysis indicate that blood pressure (systolic blood pressure: odds ratio [OR], 1.02 [95% CI, 1.01-1.02]; diastolic blood pressure: OR, 1.03 [95% CI, 1.03-1.04]) and some circulating lipids (low-density lipoprotein cholesterol: OR, 1.06 [95% CI, 1.01-1.12]; apoA1: OR, 0.95 [95% CI, 0.92-0.98]; apoB: OR, 1.05 [95% CI, 1.01-1.09]; eicosapentaenoic acid: OR, 2.36 [95% CI, 1.41-3.96]) have causal relationships with the risk of IS onset. We identified 73 genes that are linked to blood pressure and circulating lipids in the context of IS, and 16 are differentially expressed associated genes. FURIN, MAN2A2, HDDC3, ALDH2, and TOMM40 were identified as feature genes for constructing the nomogram that provides a quantitative prediction of the risk of IS onset. CONCLUSIONS: This study indicates that there are causal links between blood pressure, certain circulating lipids, and the development of IS. The potential mechanisms underlying these causal relationships involve the regulation of lipid metabolism, blood pressure, DNA repair and methylation, cell apoptosis and autophagy, immune inflammation, and neuronal protection, among others.

RESUMO

Tinnitus is the abnormal perception of sound in the absence of a corresponding external acoustic stimulus, which seriously affects the patients' quality of life, physical and mental health, and the safety of life. There is almost no effective cure for tinnitus, primarily due to its complicated etiopathogenesis and unclear mechanisms. As a major and ancient physical therapy in Traditional Chinese Medicine, acupuncture has been widely used in tinnitus because of its simple operation, rapid effect, and low cost. This paper reviews the relevant literature on the treatment of different kinds of tinnitus by acupuncture, and summarizes the therapeutic efficacy and mechanism of acupuncture on tinnitus, which is expected to provide new ideas and research directions for the study of tinnitus treatment by acupuncture.

RESUMO

Gate tunable two-dimensional (2D) superconductors offer significant advantages in studying superconducting phase transitions. Here, we address superconductivity in exfoliated 1T'-MoTe2 monolayers with an intrinsic band gap of ∼7.3 meV using field effect doping. Despite large differences in the dispersion of the conduction and valence bands, superconductivity can be achieved easily for both electrons and holes. The onset of superconductivity occurs near 7-8 K for both charge carrier types. This temperature is much higher than that in bulk samples. Also the in-plane upper critical field is strongly enhanced and exceeds the BCS Pauli limit in both cases. Gap information is extracted using point-contact spectroscopy. The gap ratio exceeds multiple times the value expected for BCS weak-coupling. All of these observations suggest a strong enhancement of the pairing interaction.

RESUMO

BACKGROUND: Brassinolide, known as the seventh plant hormone, can improve the photosynthetic capacity of plants, promote plant growth and development, promote the formation of horticultural crop yield, improve the quality of horticultural crops, and also improve the ability of plants to resist biological and abiotic stresses. RESULTS: The effects of different concentrations of exogenously sprayed 2,4-epibrassinolide (EBR) on growth, physiological and photosynthetic characteristics of 'All-round large leaf coriander' were studied in substrate culture. The results showed that 0.05, 0.1, and 0.5 mg.L- 1 EBR promoted the growth of coriander and increased the aboveground fresh and dry weights, with 0.5 mg.L- 1 EBR having the most significant effect. Spraying 0.1 mg.L- 1 EBR increased the content of soluble sugars and protein of coriander leaves. Spraying 0.1 and 0.5 mg.L- 1 EBR significantly increased the chlorophyll content and photosynthetic parameters of coriander leaves, and 0.5 mg.L- 1 EBR also significantly increased the chlorophyll fluorescence parameters of coriander leaves. Spraying 0.5 mg.L- 1 EBR upregulated the expression of CsRbcS, CsFBPase, and CsAld. Correlation analysis showed that aboveground fresh weight under exogenous EBR treatment was significantly positively correlated with aboveground dry weight, plant height, Pn, Gs, Ci, and CsAld (P < 0.05), and soluble sugar content was significantly positively correlated with the number of leaves, Y(II), qP, and CsRbcS. The results of the principal component analysis (PCA) showed that there was a significant separation between the treatment and the control groups. Spraying 0.5 mg.L- 1 EBR can promote the growth of coriander, improve the quality of coriander leaves, and strengthen coriander leaf photosynthetic capacity. This study provides new insights into the promotion of coriander growth and development following the application of exogenous EBR. CONCLUSION: Exogenous EBR treatment increased coriander plant height, leaf growth and aboveground dry weight, and enhanced photosynthesis. Exogenous spraying of 0.5 mg.L- 1 EBR had the most significant effect.

RESUMO

With the recent discovery of the quantum anomalous Hall insulator (QAHI), which exhibits the conductive quantum Hall edge states without external magnetic field, it becomes possible to create a topological superconductor (SC) by introducing superconductivity into these edge states. In this case, 2 distinct topological superconducting phases with 1 or 2 chiral Majorana edge modes were theoretically predicted, characterized by Chern numbers (N) of 1 and 2, respectively. We present spectroscopic evidence from Andreev reflection experiments for the presence of chiral Majorana modes in an Nb/(Cr0.12Bi0.26Sb0.62)2Te3 heterostructure with distinct signatures attributed to 2 different topological superconducting phases. The results are in qualitatively good agreement with the theoretical predictions.

RESUMO

PURPOSE: The purpose of this study was to investigate how aerobic exercise affects oxidative stress (OS) in patients with chronic kidney disease (CKD). METHODS: Retrieval dates range from the date the database was established to 19 July 2023, without languages being restricted. A meta-analysis and sensitivity analysis were conducted using RevMan 5.3 and Stata 16.0. RESULTS: The meta-analysis showed that, compared to usual activity or no exercise, aerobic exercise significantly reduced the oxidative markers malondialdehyde (MDA) (mean differences (MD) - 0.96 (95% CI -1.33, - 0.59); p < 0.00001), advanced oxidation protein product (AOPP) (MD - 3.49 (95% CI - 5.05, - 1.93); p < 0.00001), F2-isoprostanes (F2-iso) (MD - 11.02 (95% CI - 17.79, - 4.25); p = 0.001). Aerobic exercise also increased the antioxidant marker superoxide dismutase (SOD) in CKD patients (standardized mean differences (SMD) 1.30 (95% CI 0.56, 2.04); p = 0.0005). Subgroup analysis showed a significant increase in glutathione peroxidase (GPX) in patients aged ≥60 years (SMD 2.11 (95% CI 1.69, 2.54); p < 0.00001). The change in total antioxidant capacity (TAC) after aerobic exercise was insignificant in patients with CKD. The trial sequential analysis supported aerobic exercise's effectiveness in improving MDA, SOD, AOPP, and F2-iso in patients with CKD. CONCLUSION: The results of this review suggest that aerobic exercise improves OS indicators (MDA, SOD, AOPP, and F2-iso) in CKD patients compared to conventional treatment or no exercise and that the effects on GPX and TAC indicators need further confirmation. For better validation of benefits and exploration of the best aerobic exercise regimen to improve OS status with CKD, further studies with high methodological quality and large sample sizes are needed.

RESUMO

Low-light intensity affects plant growth and development and, finally, causes a decrease in yield and quality. There is a need for improved cropping strategies to solve the problem. We previously demonstrated that moderate ammonium:nitrate ratio (NH4+:NO3-) mitigated the adverse effect caused by low-light stress, although the mechanism behind this alleviation is unclear. The hypothesis that the synthesis of nitric oxide (NO) induced by moderate NH4+:NO3- (10:90) involved in regulating photosynthesis and root architecture of Brassica pekinesis subjected to low-light intensity was proposed. To prove the hypothesis, a number of hydroponic experiments were conducted. The results showed that in plants exposed to low-light intensity, the exogenous donors NO (SNP) and NH4+:NO3- (N, 10:90) treatments significantly increased leaf area, growth range, and root fresh weight compared with nitrate treatment. However, the application of hemoglobin (Hb, NO scavenger), N-nitro-l-arginine methyl ester (L-NAME, NOS inhibitor), and sodium azide (NaN3, NR inhibitor) in N solution remarkably decreased the leaf area, canopy spread, the biomass of shoot and root, the surface area, and volume and tips of the root. The application of N solution and exogenous SNP significantly enhanced Pn (Net photosynthetic rate) and rETR (relative electron transport rates) compared with solo nitrate. While all these effects of N and SNP on photosynthesis, such as Pn, Fv/Fm (maximum quantum yield of PSII), Y(II) (actual photosynthetic efficiency), qP (photochemical quenching), and rETR were reversed when the application of Hb, L-NAME, and NaN3 in N solution. The results also showed that the N and SNP treatments were more conducive to maintaining cell morphology, chloroplast structure, and a higher degree of grana stacking of low-light treated plants. Moreover, the application of N significantly increased the NOS and NR activities, and the NO levels in the leaves and roots of mini Chinese cabbage seedlings treated with N were significantly higher than those in nitrate-treated plants. In conclusion, the results of this study showed that NO synthesis induced by the appropriate ammonia-nitrate ratio (NH4+:NO3- = 10:90) was involved in the regulation of photosynthesis and root structure of Brassica pekinesis under low-light stress, effectively alleviating low-light stress and contributing to the growth of mini Chinese cabbage under low-light stress.

RESUMO

Treatment of the planting and breeding waste is becoming a big issue due to their significant quantities. Composting could be an effective alternative for planting and breeding waste management which could be used as fertilizer. The purpose of this research was to evaluate the effect of planting and breeding waste on baby cabbage growth and soil properties, to establish a suitable agricultural cycle model for semi-arid area in central Gansu Province. The planting and breeding wastes [sheep manure (SM), tail vegetable (TV), cow manure (CM), mushroom residue (MR) and corn straw (CS)] were used as the raw materials in this study, which were designed 8 compost formulas for composting fermentation. With no fertilization (CK1) and local commercial organic fertilizer (CK2) as the control, the comprehensive evaluation of planting and breeding waste composts on the yield of baby cabbage, fertilizer utilization rate, soil physical and chemical properties and microbial diversity were studied to select the best compost formula suitable for the growth of baby cabbage. And the material flow and energy flow analysis of the circulation model established by the formula were carried out. The results showed that the biological yield and economic yield of baby cabbage, absorption and recycling utilization of total phosphorus (TP) and total potassium (TK) reached the maximum under the formula of SM: TV: MR: CS = 6:2:1:1. Compared with CK2, the formula of SM: TV: MR: CS = 6:2:1:1 significantly increased the richness of soil bacteria and beneficial bacteria Proteobacteria, and decreased the relative abundance of harmful bacteria Olpidiomycota. Principal component analysis showed the comprehensive score of SM: TV: MR: CS = 6:2:1:1 was the best organic compost formula suitable for producing high-quality and high-yield baby cabbage and improving soil environment. Therefore, this formula can be used as a reference organic fertilizer formula for field cultivation of baby cabbage.

RESUMO

Meta-analysis and integrative bioinformatics were employed to comprehensively study the efficacy, safety, and mechanism of Huangkui Capsules in treating chronic kidney disease(CKD). CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, and Web of Science were searched for randomized controlled trial(RCT) of Huangkui Capsules for CKD from inception to January 3, 2023. The outcome indicators included urine protein, serum creatinine(Scr), and blood urea nitrogen(BUN) levels, and Cochrane Handbook 5.1 and RevMan 5.3 were employed to perform the Meta-analysis of the included RCT. The active ingredients of Huangkui Capsules were retrieved from CNKI, and the targets of CKD from GeneCards, OMIM, and TTD. Cytoscape 3.8.0 was used to build a "component-disease" network and a protein-protein interaction(PPI) network for the screening of core components and targets. Next, a differential analysis of the core targets of Huangkui Capsules for treating CKD was conducted with the clinical samples from GEO to identify the differentially expressed core targets, and correlation analysis and immune cell infiltration analysis were then performed for these targets. A total of 13 RCTs were included for the Meta-analysis, involving 2 372 patients(1 185 in the observation group and 1 187 in the control group). Meta-analysis showed that the Huangkui Capsules group and the losartan potassium group had no significant differences in reducing the urinary protein levels after 12(MD=19.60, 95%CI[-58.66, 97.86], P=0.62) and 24 weeks(MD=-66.00, 95%CI[-264.10, 132.11], P=0.51) of treatment. Huangkui Capsules in combination with conventional treatment was superior to conventional treatment alone(MD=-0.55, 95%CI[-0.86,-0.23], P=0.000 6). Huangkui Capsules combined with conventional treatment was superior to conventional treatment alone in recovering Scr(MD=-9.21, 95%CI[-15.85,-2.58], P=0.006) and BUN(MD=-1.02, 95%CI[-1.83,-0.21], P=0.01). Five patients showed clear adverse reactions, with abdominal or gastrointestinal discomfort. Huangkui Capsules had 43 active ingredients and 393 targets, and the core ingredients were myricetin, quercetin, gossypin, elaidic acid, dihydromyricetin, isochlorogenic acid B, and caffeic acid. CKD and Huangkui Capsules shared 247 common targets, including 25 core targets. The GEO differential analysis predicted 18 differentially expressed core targets, which were mainly positively correlated with immune cell expression and involved in immune inflammation, oxidative stress, pyroptosis, lipid metabolism, sex hormone metabolism, and cell repair. Conclusively, Huangkui Capsules combined with conventional treatment significantly reduced urine protein, Scr, and BUN. Huangkui Capsules alone and losartan potassium had no significant difference in reducing urine protein. This efficacy of Huangkui Capsules may be associated with the multi-component, multi-target, and multi-pathway responses to immune inflammation and oxidative stress. The included RCT had small sample sizes and general quality. More clinical trial protocols with large sample sizes and rigorous design and in line with international norms are needed to improve the evidence quality, and the results of bioinformatics analysis remain to be confirmed by further studies.

RESUMO

BACKGROUND: Type 2C protein phosphatase (PP2C) is a negative regulator of ABA signaling pathway, which plays important roles in stress signal transduction in plants. However, little research on the PP2C genes family of cucumber (Cucumis sativus L.), as an important economic vegetable, has been conducted. RESULTS: This study conducted a genome-wide investigation of the CsPP2C gene family. Through bioinformatics analysis, 56 CsPP2C genes were identified in cucumber. Based on phylogenetic analysis, the PP2C genes of cucumber and Arabidopsis were divided into 13 groups. Gene structure and conserved motif analysis showed that CsPP2C genes in the same group had similar gene structure and conserved domains. Collinearity analysis showed that segmental duplication events played a key role in the expansion of the cucumber PP2C genes family. In addition, the expression of CsPP2Cs under different abiotic treatments was analyzed by qRT-PCR. The results reveal that CsPP2C family genes showed different expression patterns under ABA, drought, salt, and cold treatment, and that CsPP2C3, 11-17, 23, 45, 54 and 55 responded significantly to the four stresses. By predicting the cis-elements in the promoter, we found that all CsPP2C members contained ABA response elements and drought response elements. Additionally, the expression patterns of CsPP2C genes were specific in different tissues. CONCLUSIONS: The results of this study provide a reference for the genome-wide identification of the PP2C gene family in other species and provide a basis for future studies on the function of PP2C genes in cucumber.

RESUMO

A biosynthetic precursor of tetrapyrrol, 5-aminolevulinic acid (ALA), is widely used in agricultural production, as an exogenous regulatory substance that effectively regulates plant growth. Previous studies have shown that heme and chlorophyll accumulate in plants under salt stress, when treated with exogenous ALA. In this study, we explored the regulatory role of heme in plants, by spraying 25 mg L-1 ALA onto the leaves of cucumber seedlings treated with heme synthesis inhibitor (2,2'-dipyridyl, DPD) and heme scavenger (hemopexin, Hx), under 50 mmol L-1 NaCl stress. The results showed that NaCl alone and DPD + Hx treatments to cucumber seedlings subjected to salt stress adversely affected their growth, by decreasing biomass accumulation, root activity, and root morphology. In addition, these treatments induced an increase in membrane lipid oxidation, as well as enhancement of anti-oxidase activities, proline content, and glutamate betaine. However, exogenous ALA application increased the plant growth and root architecture indices under NaCl stress, owing to a lack of heme in the seedlings. In addition, cucumber seedlings treated with DPD and Hx showed inhibition of growth under salt stress, but exogenous ALA effectively improved cucumber seedling growth as well as the physiological characteristics; moreover, the regulation of ALA in plants was weakened when heme synthesis was inhibited. Heme biosynthesis and metabolism genes, HEMH and HO1, which are involved in the ALA metabolic pathway, were upregulated under salinity conditions, when ferrochelatase activity was inhibited. Application of exogenous ALA increased the heme content in the leaves. Thus, exogenous ALA may supplement the substrates for heme synthesis. These results indicated that heme plays a vital role in the response of plants to salinity stress. In conclusion, heme is involved in ALA-mediated alleviation of damage caused to cucumber seedlings and acts as a positive regulator of plant adaption.

RESUMO

Transition metal dichalcogenides like 2H-NbSe_{2} in their two-dimensional (2D) form exhibit Ising superconductivity with the quasiparticle spins being firmly pinned in the direction perpendicular to the basal plane. This enables them to withstand exceptionally high magnetic fields beyond the Pauli limit for superconductivity. Using field-angle-resolved magnetoresistance experiments for fields rotated in the basal plane we investigate the field-angle dependence of the upper critical field (H_{c2}), which directly reflects the symmetry of the superconducting order parameter. We observe a sixfold nodal symmetry superposed on a twofold symmetry. This agrees with theoretical predictions of a nodal topological superconducting phase near H_{c2}, together with a nematic superconducting state. We demonstrate that in NbSe_{2} such unconventional superconducting states can arise from the presence of several competing superconducting channels.

RESUMO

To address the low Ca-induced growth inhibition of tomato plants, the mitigation effect of exogenous Si on tomato seedlings under low-Ca stress was investigated using different application methods. We specifically analyzed the effects of root application or foliar spraying of 1 mM Si on growth conditions, leaf photosynthetic properties, stomatal status, chlorophyll content, chlorophyll fluorescence, ATP activity and content, Calvin cycle-related enzymatic activity, and gene expression in tomato seedlings under low vs. adequate calcium conditions. We found that the low-Ca environment significantly affected (reduced) these parameters, resulting in growth limitation. Surprisingly, the application of 1 mM Si significantly increased plant height, stem diameter, and biomass accumulation, protected photosynthetic pigments, improved gas exchange, promoted ATP production, enhanced the activity of Calvin cycle key enzymes and expression of related genes, and ensured efficient photosynthesis to occur in plants under low-Ca conditions. Interestingly, when the same amount of Si was applied, the beneficial effects of Si were more pronounced under low-Ca conditions that under adequate Ca. We speculate that Si might promote the absorption and transport of calcium in plants. The effects of Si also differed depending on the application method; foliar spraying was better in alleviating photosynthetic inhibition in plants under low-Ca stress, whereas root application of Si significantly promoted root growth and development. Enhancing the photosynthetic capacity by foliar Si application is an effective strategy for ameliorating the growth inhibition of plants under low-Ca stress.

RESUMO

The present study evaluated the efficacy and safety of Xiangju Capsules in the treatment of sinusitis. CNKI, Wanfang, VIP, CBM, Cochrane Library, PubMed, EMbase, Web of Science and ClinicalTrials.gov were systematically searched for randomized controlled trials(RCTs) of Xiangju Capsules in the treatment of sinusitis, and Meta-analysis was performed on the included articles using RevMan 5.3. Twenty-nine articles were included, involving 4 331 cases, including 2 196 cases in the experimental group and 2 135 cases in the control group. Meta-analysis results showed that the conventional therapy combined with Xiangju Capsules showed better significant efficiency(RR=1.30, 95%CI[1.15, 1.47], P<0.000 01), total response rate(RR=1.19, 95%CI[1.16, 1.23], P<0.000 01), and Lund-Mackay scores(MD=-1.23, 95%CI[-1.39,-1.07], P<0.000 01) than conventional therapy alone. The conventional therapy combined with Eucalyptol-limonene-pinene Enteric Soft Capsules and Xiangju Capsules showed better total response rate(RR=1.14, 95%CI[1.07, 1.21], P<0.000 1) and VAS scores than conventional therapy combined with Eucalyptol-limonene-pinene Enteric Soft Capsules(MD_(headache)=-1.29, 95%CI[-1.48,-1.10], P<0.000 01; MD_(congestion)=-1.08, 95%CI[-1.21,-0.95], P<0.000 01; MD_(olfactory dysfunction)=-1.05, 95%CI[-1.23,-0.87], P<0.000 01; MD_(facial disorder)=-1.38, 95%CI[-1.49,-1.27], P<0.000 01). The conventional therapy combined with clarithromycin and Xiangju Capsules displayed a better total response rate(RR=1.15, 95%CI[1.08, 1.21], P<0.000 01) than conventional therapy combined with clarithromycin, while no significant difference was observed in the significant efficiency(RR=1.27, 95%CI[0.98, 1.65], P=0.07). The significant efficiency(RR=2.16, 95%CI[1.47, 3.18], P<0.000 1) and total effective rate(RR=1.48, 95%CI[1.28, 1.72], P<0.000 01) of clarithromycin combined with Xiangju Capsules in patients with sinusitis and CT scores(MD=-1.87, 95%CI[-2.01,-1.74], P<0.000 01) was significantly better than clarithromycin alone. Trial sequential analysis(TSA) showed that the cumulative sample size of the main outcome indicators had met expectations. The main adverse reactions included drowsiness, diarrhea, and abdominal pain, which had no direct relationship with Xiangju Capsules. Based on the available data and methods, the combination of Xiangju Capsules with multiple treatments showed significant efficiency and total response rate in the treatment of sinusitis, and improved CT scores, VAS scores, and Lund-Mackay scores, without serious adverse reactions. The efficacy and safety of Xiangju Capsules in the treatment of sinusitis still need to be verified by a large-sample, well-designed, and internationally standardized clinical trial scheme.

To expeditiously assess the efficacy and safety of Binghuang Fule Ointment in the treatment of eczema, we screened out the papers with randomized controlled trials(RCTs) for studying the efficacy of Binghuang Fule Ointment in the treatment of eczema from CNKI, VIP, Wanfang, SinoMed, PubMed, Web of Science, Cochrane Library, and EMbase and then performed Meta-analysis of the included studies via RevMan 5.4. A total of 19 studies were included, involving 1 919 cases(973 cases in the experimental group and 946 cases in the control group). Meta-analysis results showed that Binghuang Fule Ointment combined with conventional western medicine had better efficacy score index(clinical effectiveness ≥60%)(RR=1.32, 95%CI[1.13, 1.55], P=0.000 4) and lower recurrence rate(RR=0.37, 95%CI[0.20, 0.65], P=0.000 7) than conventional western medicine alone. The adverse reactions(RR=1.05, 95%CI[0.52, 2.15], P=0.88) did not show significant difference between the two groups. The application of Binghuang Fule Ointment alone had better efficacy score index(clinical effectiveness≥60%)(RR=1.20, 95%CI[1.09, 1.33], P=0.000 3) than conventional western medicine alone and the adverse reactions(RR=0.92, 95%CI[0.45, 1.89], P=0.82) insignificantly different from conventional western medicine alone. Binghuang Fule Ointment alone or combined with conventional western medicine demonstrated better effective in remission of symptoms and signs(clinical effectiveness)(RR=1.41, 95%CI[1.07, 1.85], P=0.01) than conventional western medicine alone. Compared with the single application of western medicine, Binghuang Fule Ointment alone or combined with conventional western medicine has better curative effect, low recurrence rate, and equivalent safety in the treatment of eczema. Nevertheless, owing to the low quality of the included papers, randomized controlled trials with large sample size, multiple centers, high methodological quality are needed to further verify the efficacy and safety of Binghuang Fule Ointment in the treatment of eczema.

RESUMO

This study systematically evaluated the efficacy and safety of Ganshuang Granules in the treatment of liver injury, so as to provide a new choice for patients with liver injury. CNKI, Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, and Web of Science were systematically searched for the randomized controlled trial(RCT) of Ganshuang Granules in the treatment of liver injury. RevMan 5.4 was employed to perform the Meta-analysis of the included RCT according to the Cochrane Handbook 5.1. A total of 3 005 patients were included in 38 RCTs, including 1 536 patients in the observation group and 1 469 in the control group. The results of Meta-analysis showed that Ganshuang Granules combined with conventional therapy was superior to the therapy in the control group in reducing alanine aminotransferase(ALT)(MD=-24.12, 95%CI[-32.17,-16.07], P<0.000 01), aspartate aminotransferase(AST)(MD=-23.24, 95%CI[-29.70,-16.78], P<0.000 01), total bilirubin(TBiL)(MD=-12.42, 95%CI[-14.62,-10.22], P<0.000 01), and gamma-glutamyl transpeptidase(GGT)(MD=-21.32, 95%CI[-33.61,-9.03], P=0.000 7). Compared with the control group, the observation group had witnessed a significant increase in albumin(ALB)(MD=4.94, 95%CI[4.44, 5.45], P<0.000 01). No significant adverse reactions were observed. According to the available data, Ganshuang Granules combined with conventional therapy can effectively recover the levels of ALT, AST, TBiL, GGT, and ALB in patients with liver injury. Nevertheless, high-quality RCT is still needed to further verify the findings of this study.

RESUMO

This study aims to evaluate the effectiveness and safety of Ningmitai Capsules in the treatment of urinary tract infection.To be specific, articles on the treatment of urinary tract infection with Ningmitai Capsules were retrieved from China National Know-ledge Infrastructure(CNKI), Wanfang, VIP, SinoMed, Cochrane Library, PubMed, EMbase, and Web of Science(from establishment to October 2021).Eligible randomized controlled trials(RCTs) were screened out, and ROB and RevMan 5.3 of Cochrane were employed for data integration and Meta-analysis.Finally, 17 articles were included, involving 1 972 cases, with 1 045 in the experimental group and 927 in the control group.The Meta-analysis results are as follows.Ningmitai Capsules combined with conventional antibiotics was superior to sensitive antibiotics alone in the treatment of acute pyelonephritis in aspects of clinical cure rate(RR=1.94, 95%CI[1.58, 2.37], P<0.000 01), reduction in the count of red blood cells in the urine(MD=-3.22, 95%CI[-3.23,-3.21], P<0.000 01), decrease in the count of white blood cells in the urine(MD=-2.34, 95%CI[-2.59,-2.10], P<0.000 01), and time for the disappearance of the symptoms(MD_(time for urinary tract irritation disappeared)=-2.19, 95%CI[-2.69,-1.68], P<0.000 01; MD_(time for waist aches disappeared)=-3.58, 95%CI[-4.20,-2.97], P<0.000 01; MD_(time for heating disappeared)=-0.57, 95%CI[-0.81,-0.33], P<0.000 01).The combination of either cephalosporin or quinolone with Ningmitai Capsules can improve clinical cure rate of acute pyelonephritis(RR_(combined with cephalosporin)=1.94, 95%CI[1.56, 2.42], P<0.000 01; RR_(combined with quinolone)=1.91, 95%CI[1.16, 3.15], P=0.01).The clinical cure rate(RR=1.91, 95%CI[1.47, 2.49], P<0.000 01) of diabetes complicated with urinary tract infection by Ningmitai Capsules was higher than that by quinolones.The clinical cure rate(RR=1.22, 95%CI[1.09, 1.37], P=0.000 5) of non-gonococcal urethritis by Ningmitai Capsules combined with conventional tetracycline and macrolide antibiotics was higher than that by conventional antibiotics.Ningmitai Capsules combined with conventional antibiotics/Ningmitai Capsules alone was superior to conventional antibiotics alone in the treatment of urinary tract infection in terms of the clinical cure rate(RR=1.35, 95%CI[1.17, 1.56], P<0.000 1) and incidence of adverse reactions(RR=0.32, 95%CI[0.15, 0.68], P=0.003), particularly the combination with quinolone antibiotics(RR=1.30, 95%CI[1.04, 1.61], P=0.02).The main adverse reactions were mild gastrointestinal discomfort, nausea, vomiting, and dry mouth.In summary, Ningmitai Capsules combined with conventional sensitive antibiotics/Ningmitai Capsules alone can improve the clinical cure rate of patients with urinary tract infection.Ningmitai Capsules combined with conventional sensitive antibiotics can significantly reduce the time for symptom disappearance of acute pyelonephritis and down-regulate the counts of red and white blood cells in the urine compared with antibiotics alone, and no serious adverse reactions have been found.However, in light of the low proportion of quality eligible articles, experiments with rigorous design, large sample size, and complete outcome in-dexes should be carried out in the future to verify the clinical efficacy and safety of Ningmitai Capsules in the treatment of urinary tract infection.

RESUMO

The present study systematically sorted out the existing research on Qilong Capsules in the treatment of ischemic stroke with Qi deficiency and blood stasis syndrome and comprehensively evaluated its clinical evidence and value to highlight the advantages and characteristics of products and provide references for the decision-making of national pharmaceutical management departments. Based on the evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, and pharmacoeconomics, the qualitative and quantitative evaluation of "6+1" dimensions of safety, effectiveness, economy, innovation, suitability, and accessibility, as well as characteristics of traditional Chinese medicine(TCM) was performed with multi-criteria decision analysis(MCDA) mo-del using the information, such as public data, literature data, pharmaceutical research, and questionnaire survey, and CSC v2.0 was used to calculate the clinical value of Qilong Capsules. The evaluation results were grade A, B, C, or D. Spontaneous reporting system(SRS) monitoring data, literature reports, clinical trials, and other multi-source safety evidence showed that the main adverse reactions of this drug included dry mouth, nausea, and rash, and no severe adverse reactions was found. The evidence was sufficient with small and controllable known risks, and the safety was grade A. Meta-analysis showed that Qilong Capsules combined with conventional western medicine in the treatment of acute ischemic stroke was superior to the control group in improving neurological deficits, clinical total response rate, patients' activities of daily living, and hemorheological indexes. The level of evidence was high with manifest clinical significance, and the effectiveness was grade A. The results of pharmacoeconomic research showed that Qilong Capsules combined with conventional western medicine in the treatment of ischemic stroke were advantageous in cost-effectiveness as compared with conventional western medicine alone, but the incremental effect was not significant. The quality evaluation results of the economic report were comparatively clear, and the economy was grade B. Aiming at major cerebrovascular diseases in the society and giving full play to the advantages of TCM, Qilong Capsules focused on the inheritance of classics and scientific and technological innovation, and innovation was grade B. The results of the questionnaire survey showed that the technical characteristics and drug application could meet the medication needs of clinical doctors and patients, and the suitability was grade B. The price level of this drug was comparatively high and the affordability was good since the treatment cost accounted for a small proportion of disposable income. The drug accessibility was good with a wide range of drug sales, sufficient production capacity, and sustainable medicinal materials resources, and was grade B. This drug was derived from the classic prescription Buyang Huanwu Decoction with rich experience of human application, which could regulate Qi and blood circulation, and the section of TCM characteristics was grade B. Based on the evidence evaluation results of "6+1" dimensions of Qilong Capsules, the comprehensive evaluation of clinical value was class A. It is suggested that it can be transformed into relevant policy results of basic clinical medication management according to procedures.

RESUMO

This study systematically sorted out the evidence data of the safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine(TCM) of Reyanning Mixture in the treatment of acute upper respiratory tract infection(heat-toxin attacking lung syndrome) with the qualitative and quantitative evaluation methods adopted. Based on evidence-based medicine, epidemiology, clinical medicine, evidence-based pharmacy, pharmacoeconomics, and health technology evalua-tion(HTA), the clinical value of Reyanning Mixture was evaluated using multi-criteria decision analysis(MCDA) model, Chinese patent medicine clinical evidence, and value evaluation software(CSC v2.0). The SRS monitoring data, Meta-analysis, and other safety evidence showed that the main adverse reactions of Reyanning Mixture were nausea, diarrhea, and rash, and no serious adverse reactions were found. The pharmacovigilance system was sound, and the system was perfect. There was no recall, notification, or interview for unqualified products. Based on the existing research, the evidence was sufficient, and the risk was controllable. Hence, its safety was grade A. Meta-analysis showed that in the treatment of acute upper respiratory tract infection, Reyanning Mixture combined with Amoxicillin Capsules was better than Amoxicillin Capsules alone in shortening the complete fever relief time and improving the cure rate. Besides, it was superior to Shuanghuanglian Granules in shortening the complete fever relief time, cough relief time, nasal congestion relief time, and pharyngeal congestion relief time. The Meta-analysis was conducted based on AMSTAR standard, and its ove-rall quality was proved good. The evidence quality in GRADE system evaluation was medium and low. The quality of evidence was medium, and the clinical value was obvious. Hence, its effectiveness was grade A. The results of pharmacoeconomic research showed that compared with Amoxicillin Capsules, Reyanning Mixture alone or in combination with Amoxicillin Capsules had cost-effectiveness advantages in the treatment of acute upper respiratory tract infection, and the results were stable in sensitivity analysis. According to the CASP economic evaluation checklist, the research problems were clear and the results were reliable. As revealed by the comprehensive evaluation, the evidence quality was sufficient and the result was clear. Its economy was grade B. Reyanning Mixture had multiple therapeutic targets like anti-virus, anti-bacteria, antipyresis, and anti-cough, with good clinical innovation. There were many innovative initiatives in ensuring drug supply, especially at the grass roots, drug safety, and effectiveness, and also multiple innovative contributions to production technology, quality control, scientific and technological research and development, and enterprise management and marketing. Therefore, its innovation was grade B. The dosage form of Reyanning was mixture, which made it convenient for storage and transportation. The usage was easy to be mastered and accepted by doctors and nurses, exhibiting good suitability for clinicians, nurses, pharmacists, and patients who received this drug and basically meeting the needs of clinical medication. The suitability was grade B. The average daily cost of this drug was 8.082 yuan, and the price was low. The treatment cost accounted for a small proportion of the annual disposable income of urban and rural residents, indicating that it was affordable. Reyanning Mixture was available in 31 provinces, cities and autonomous regions, covering 6 910 hospitals. The allocation of hospitals at all levels was more than 50%. There was no shortage or supply restriction of medicinal material resources. The annual production capacity was sufficient to meet the supply demand, so its accessibility was grade A. Reyanning Mixture, sourced from "pneumonia Ⅲ", has been subjected to a real-world study of its clinical application, with 4 367 cases involved, and the characteristic of TCM was grade B. The comprehensive evaluation results demonstrated that the clinical value score of Reyanning Mixture in the treatment of acute upper respiratory tract infection(heat-toxin attacking lung syndrome) was 0.80, making it rated class A. According to the Guidelines for Management of Comprehensive Clinical Evaluation of Drugs(trial version 2021), it is recommended to convert it into the relevant policy results of basic clinical medication management according to the procedures.

RESUMO

This study aims to assess the efficacy and safety of Hulisan Capsules in the treatment of knee osteoarthritis, which is expected to serve as a reference for clinical practice. To be specific, randomized controlled trial(RCT) on the treatment of knee osteoarthritis with Hulisan Capsules was retrieved from EMbase, PubMed, Cochrane Library, Web of Science, CNKI, Wanfang, SinoMed, and VIP(from inception to November 15, 2021). Two researchers independently screened the articles, extracted the data, and evaluated the risk of bias with ROB. RevMan 5.4 was used for Meta-analysis. Finally, 12 RCTs were screened out, involving 1 703 cases(1 075 in the experimental group and 628 in the control group). Meta-analysis showed that conventional treatment + Hulisan Capsules was superior to conventional treatment alone in terms of symptom relief rate(RR=1.19, 95%CI[1.09, 1.30], P<0.000 1), Lysholm score(MD=11.17, 95%CI[7.35, 15.00], P<0.000 01), visual analogue scale(VAS) score(MD=-0.99, 95%CI[-1.30,-0.68], P<0.000 01), and knee function score(RR=8.94, 95%CI[6.51, 11.37], P<0.000 01). Hulisan Capsules alone was superior to the conventional treatment alone in terms of the symptom relief rate(RR=1.38, 95%CI[1.13, 1.69], P=0.002) and knee function score(MD=2.88, 95%CI[0.81, 4.94], P=0.006), but VAS score was insignificantly different between the patients treated with Hulisan Capsules alone and those with conventional treatment alone(MD=-0.57, 95%CI[-1.42, 0.29], P=0.19). Hulisan Capsules + conventional treatment showed insignificant difference in symptom relief rate from the Zhuifeng Tougu Capsules + conventional treatment(RR=1.07, 95%CI[0.91, 1.25], P=0.44). The Lequesne score was insignificantly different between Hulisan Capsules + conventional treatment and conventional treatment/Zhuifeng Tougu Capsules + conventional treatment(MD=-2.17, 95%CI[-6.29, 1.96], P=0.30). The incidence of adverse reactions in the experimental group was significantly lower than control group(RR=0.57, 95%CI[0.34, 0.96], P=0.03). According to the available data and methods, Hulisan Capsules/Hulisan Capsules + conventional treatment could improve the symptom relief rate, Lysholm score, knee function score, and VAS score of patients with knee osteoarthritis, and alleviate the symptoms of pain, stiffness, and swelling of them. No serious adverse reactions were found yet. In the future, more large-sample and standard clinical trials are needed to verify the effect and safety of Hulisan Capsules in the treatment of knee osteoarthritis.
