RESUMO

Astragali Radix is commonly used as bulk medicinal materials. Chinese Pharmacopoeia contains about 150 compound preparations of Astragali Radix, but the sample preparation method under the determination of Astragali Radix content in Chinese Pharmacopoeia is tedious and time-consuming, not convenient for the test of a large number of samples. Therefore, it is of great significance to simplify the sample preparation method and improve the practicability of the method for the quality control of Astragali Radix and its preparations. In this study, ultrasonic extraction method was used instead of heated reflux extraction, and solid phase extraction method was used to enrich and prepare the samples. A set of practical quality evaluation method was established for Astragali Radix slices and standard decoction, greatly shortening the sample preparation time and improving the accuracy of the method. The results of Astragali Radix standard decoction analysis showed that the transfer rate of calycosin 7-O-ß-D-glucospyranoside,(96.5±28.7)%, had great variation, which was found to be related to the conversion of mulberry isoflavone glucoside into calycosin 7-O-ß-D-glucospyranoside during the preparation of standard decoction. The transfer rates were(59.4±14.4)% and(101.3±12.3)% for calycosin and astragaloside Ⅳ respectively, which were relatively stable. Therefore, it is suggested that Astragali Radix slices and water decoction preparations should be evaluated by using calycosin and astragaloside Ⅳ as the quality evaluation index. The results provide a scientific and practical method for quality control of Astragali Radix slices and its standard decoction, and also provide scientific evidence for quality evaluation of the preparations.

RESUMO

To establish a content determination method for quality control of the pieces and standard decoction of honey-fried Descurainiae Semen. Standard decoction of honey-fried Descurainiae Semen was prepared with standardized process, and high performance liquid chromatography coupled with diode-array detector(HPLC-DAD) was used to detect its characteristic fingerprint and determine the content of quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside. In addition, the transfer rate, dry extract rate and pH value were calculated. The results showed that the established method had a high accuracy. The content of quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside in 13 batches of standard decoction was 0.03-0.12 mg·mL~(-1); the transfer rate was 13.4%-23.1%; the rate of extracts was 1.9%-5.5%, and the pH was between 5.4-5.9. The similarity coefficients were all greater than 0.85, indicating good homogeneity for the different batches of decoction. There were 7 common peaks in the characteristic chromatogram, one of which was quercetin-3-O-ß-D-glucose-7-O-ß-D-gentiobioside. In this paper, the established content determination and quality evaluation method for Descurainiae Semen pieces and decoction was simple, rapid and reproducible, providing reference for the quality control of honey-fried Descurainiae Semen pieces, standard decoction and its preparations.

RESUMO

Mesenchymal stem cells (MSCs) have exhibited enormous therapeutic potential because of their indispensable regenerative, reparative, angiogenic, anti-apoptotic, and immunosuppressive properties. MSCs can best differentiate into mesodermal cell lineages including osteoblasts, adipocytes, muscle cells, endothelial cells and chondrocytes. Specific differentiation of MSCs could be induced through limited conditions. In addition to the relevant differentiation factors, drastic changes also occur in microenvironment to conduct it in an optimal manner for particular differentiation. Recent evidence suggests that the behavior of mitochondria participates in the regulating on direction and process of MSCs differentiation. Therefore, our current review focuses on how the behavior of mitochondria participates in both osteogenesis and adipogenesis of MSC differentiation. Besides that, in our current review, we try to provide an further understanding of the relationship between the behavior of mitochondria and the direction of MSC differentiation, which could optimize current cellular culturing protocols for benefit further tissue engineering by adjusting specific conditions of stem cells.

RESUMO

Many studies have focused on the significant role of biofilm formation by Bacillus in the biocontrol process. Bacillus pumilus HR10 is a plant growth-promoting rhizobacterium with multiple biocontrol functions, including promoting growth, controlling pathogens, and assisting in the formation of mycorrhizae. Currently, there is no relevant report on the biofilm formation of B. pumilus HR10 and its influencing factors. B. pumilus HR10 was found to easily form a stable biofilm structure on the surface of media, with awesome swarming ability. The optimum temperature for biofilm formation was 37 °C. B. pumilus HR10 formed most obviously at pH 7.0 and was not extremely sensitive to acidic or alkaline conditions. Most of the polysaccharide components of plant root exudates promoted the biofilm formation by B. pumilus HR10, with glucose having the greatest promoting effect. Low concentrations of Fe2+, Mg2+, Ca2+, K+, and Na+ enhanced biofilm formation. In summary, biofilm formation can improve the tolerance of B. pumilus HR10 to salt and certain heavy metal ion stresses and contribute to its application in different plants and soils with high salinity or heavy metals in the field.

RESUMO

BACKGROUND: There is evidence that microRNA (MIR) 122 is a biomarker for various liver diseases in adults and children. To date, MIR122 has not been explored in children with intestinal failure-associated liver disease (IFALD, or hyperbilirubinemia associated with prolonged parenteral nutrition). OBJECTIVES: This study's purpose was to investigate changes in plasma miR-122, correlate miR-122 with serum liver function tests and enzymes, and investigate changes in whole blood transcripts including miR-122 targets in a group of children with IFALD who received pure intravenous fish oil (FO) as a treatment for cholestasis. METHODS: This was a prospective, observational study that enrolled children with IFALD who received intravenous FO (1 g/kg/d) and whose cholestasis resolved with FO. Plasma miR-122 was measured using reverse transcription-quantitative real-time PCR, and whole blood miR-122 targets were quantified using RNA sequencing. RESULTS: Fourteen subjects with median age 6 mo (IQR: 3-65 mo) were enrolled. RNA sequence data were available for 4 subjects. When compared with the start of FO, median miR-122 concentrations at 6 mo of FO therapy decreased [1.0 (IQR: 1.0-1.0) compared with 0.04 (IQR: 0.01-0.6), P = 0.009]. At the start of FO, miR-122 correlated with conjugated bilirubin (r = 0.56; P = 0.038). At ∼3 mo of FO, miR-122 correlated with conjugated bilirubin (r = 0.56; P = 0.045). Reactive oxygen species, heme metabolism, coagulation, adipogenesis, IL-6-Janus kinase-signal transducer and activator of transcription (JAK-STAT) 3, IL-2-STAT5, transforming growth factor-ß, TNF-α, inflammatory response, mammalian target of rapamycin gene families (normalized enrichment scores < -1.4), and miR-122 target genes were significantly downregulated with FO. CONCLUSIONS: In this small cohort of young children with IFALD, miR-122 decreased with FO therapy and correlated with conjugated bilirubin. Key pathways involving oxidation, inflammation, cellular differentiation, and nutrient regulation were downregulated. Data from this study provide information about IFALD and FO. This trial was registered at www.clinicaltrials.gov as NCT00969332.

RESUMO

Refractoriness to conventional chemotherapy is a major challenge in the treatment of advanced ovarian cancer (OC). There is increasing evidence that mitochondrial priming correlates with cisplatin response in various cancers. Notably, Bim and Bid, two of the proapoptotic BH3-only proteins, are recognized as the most effective inducers of mitochondrial priming in OC. In this study, we constructed two tumor-specific oncolytic adenoviruses (Ads) coding for Bim (Ad-Bim) or truncated Bid (Ad-tBid), respectively, and performed gain-of-function assays in nine OC cell lines. Ad-tBid exhibited significant antitumor efficacy than the controls. On addition of Ad-tBid pretreatment, mito-primed cells displayed more sensitivity to cisplatin both in vitro and ex vivo. We also found that Ad-tBid induced mitochondrial apoptosis in a Bak-dependent manner. Furthermore, a combined cisplatin plus Ad-tBid therapy markedly inhibited tumor growth in a subcutaneous xenotransplanted tumor model. In mice bearing peritoneal disseminated OC, intraperitoneal administration of Ad-tBid potentiated the antitumor effect of cisplatin. Our findings suggest that Ad-tBid enhances cisplatin response in OC cells, establishing the potential treatment of advanced OC via a combination of cisplatin and Ad-tBid.

RESUMO

OBJECTIVE: To evaluate efficacy of traditional Chinese medicine (TCM) for gastric precancerous lesion (GPL). METHOD: Literature retrieval was conducted in seven databases from their inception through Dec. 24th, 2018. The Cochrane collaboration, Review Manager (RevMan5.3) and GRADE profiler software were conducted for this meta-analysis. RESULTS: In primary outcomes, results of meta-analysis showed that TCM had superior to current routine pharmacotherapy (RP) in clinical efficacy, Helicobacter pylori (Hp) eradication rate, efficacy under endoscopy, and TCM syndrome efficacy. Meanwhile, no potential publication bias was detected by Begg's and Egger's tests. In secondary outcomes, compared with control groups, experimental groups were more positive effects on improvement of stomach distention, stomachache, and heartburn. CONCLUSION: Our findings indicated that TCM could have positive effects on GPL. However, further standardized RCTs of rigorous design should be required to obtain more forceful evidence.

RESUMO

Protease-activated receptor 2 (PAR2) is a member of G-protein coupled receptors, which is widely expressed in intestinal epithelium and immune cells and plays critical roles in intestinal homeostasis. Activation of PAR2 has been implicated in inflammatory process and carcinogenesis. However, it remains unclear whether and how endogenous PAR2 affects colorectal tumorigenesis. Here, we found that PAR2 expression was enhanced in patients with inflammatory bowel disease and colorectal cancer. Intriguingly, PAR2 deficiency significantly aggravated colitis and promoted tumor development in AOM/DSS model. This finding was accompanied with upregulated pro-inflammatory factors IL-6, TNFα, COX2 and NOS2 in tumors of Par2-/- mice. Moreover, PAR2 deficiency reshaped the tumor microenvironment through accumulation of tumor-promoting myeloid cells including tumor-associated macrophages and myeloid-derived suppressor cells (MDSCs) and reduction of anti-tumor T cells, which established an immunosuppressive microenvironment and facilitated tumor progression. Mechanistically, absence of PAR2 in MDSCs directly enhanced their immunosuppressive activity by promoting STAT3-mediated reactive oxygen species production. Our study reveals an unrecognized role of PAR2 in limiting colorectal carcinogenesis by regulating the tumor microenvironment. Specifically targeting PAR2 may be a potential alternative for colorectal cancer immunotherapy.

RESUMO

OBJECTIVE: Fas is a positive regulator of Th17 cells differentiation in experimental autoimmune encephalomyelitis (EAE). However, its upstream regulators are still not fully determined. This study was designed to explore the upstream regulators of Fas in regulating Th17 cells differentiation in EAE. METHODS: The mouse model of EAE was established by myelin oligodendrocyte glycoprotein injection. Th17 cells differentiation was induced by IL-23, IL-6 and TGF-ß. RESULTS: Down-regulated Hsp70 and miR-374c and up-regulated Fas were observed in the spleen and brain of EAE mice. Hsp70 overexpression evidently reduced Fas protein level, but not mRNA level. The luciferase reporter assay indicated that miR-374c targets Fas. Overexpression of miR-374c down-regulated the mRNA and protein level of Fas. The concentration of IL-17A in CD4+ T-cells was reduced by miR-374c or Hsp70 overexpression, and Fas overexpression altered this trend. Hsp70 did not regulate the expression of miR-374c, and likewise, miR-374c did not regulate the expression of Hsp70. Further results suggested that Hsp70 and miR-374c regulated Fas expression through different ways to affect Th17 cells differentiation in EAE. CONCLUSIONS: This study suggested that down-regulated miR-374c and Hsp70 promote Th17 cell differentiation by inducing Fas expression in EAE.

RESUMO

While the aberrant translocation of the mixed-lineage leukemia (MLL) gene drives pathogenesis of acute myeloid leukemia (AML), it represents an independent predictor for poor prognosis of adult AML patients. Thus, small molecule inhibitors targeting menin-MLL fusion protein interaction have been emerging for the treatment of MLL-rearranged AML. As both inhibitors of histone deacetylase (HDAC) and menin-MLL interaction target the transcription-regulatory machinery involving epigenetic regulation of chromatin remodeling that governs the expression of genes involved in tumorigenesis, we hypothesized that these two classes of agents might interact to kill MLL-rearranged (MLL-r) AML cells. Here, we report that the combination treatment with subtoxic doses of the HDAC inhibitor chidamide and the menin-MLL interaction inhibitor MI-3 displayed a highly synergistic anti-tumor activity against human MLL-r AML cells in vitro and in vivo, but not those without this genetic aberration. Mechanistically, co-exposure to chidamide and MI-3 led to robust apoptosis in MLL-r AML cells, in association with loss of mitochondrial membrane potential and a sharp increase in ROS generation. Combined treatment also disrupted DNA damage checkpoint at the level of CHK1 and CHK2 kinases, rather than their upstream kinases (ATR and ATM), as well as DNA repair likely via homologous recombination (HR), but not non-homologous end joining (NHEJ). Genome-wide RNAseq revealed gene expression alterations involving several potential signaling pathways (e.g., cell cycle, DNA repair, MAPK, NF-κB) that might account for or contribute to the mechanisms of action underlying anti-leukemia activity of chidamide and MI-3 as a single agent and particularly in combination in MLL-r AML. Collectively, these findings provide a preclinical basis for further clinical investigation of this novel targeted strategy combining HDAC and Menin-MLL interaction inhibitors to improve therapeutic outcomes in a subset of patients with poor-prognostic MLL-r leukemia.

RESUMO

We examined the role of hepatocyte micro-RNA-122 and hypothalamic neuropeptides, in weanling (21d) female rats exposed to calorie restriction induced growth restriction either prenatally (IUGR), postnatally (PNGR) or both (IPGR) vs. ad lib fed controls (CON). IUGR were hyperinsulinemic, hyperleptinemic and dyslipidemic with high circulating miR-122. In contrast, PNGR and IPGR displayed insufficient glucose, insulin and leptin amidst high ketones with a dichotomy in circulating miR-122 of PNGR

RESUMO

Diet during pregnancy has long lasting consequences on the offspring, warranting a study on the impact of early exposure to a high fat diet on the adult offspring. We hypothesized that a prenatal n-6 enriched diet will have adverse metabolic outcomes on the adult offspring that may be reversed with a postnatal n-3 enriched diet. To test this hypothesis, we examined the adult offspring from three groups: (1) n-6 group: during gestation and lactation, dams consumed an n-6 polyunsaturated fatty acid enriched diet, (2) n-3 group: gestational n-6 diet was followed by an n-3 enriched diet during lactation, and (3) a control (CD) group that received standard diet throughout gestation and lactation. Offspring from all groups weaned to a control diet ad libitum. Beginning at postnatal day 2 (P < .03) and persisting at 360 days in males (P < .04), an increase in hypothalamic AgRP expression occurred in the n-6 and n-3 groups, with an increase in food intake (P = .01), and the n-3 group displaying lower body (P < .03) and brain (P < .05) weights. At 360 days, the n-6 and n-3 groups remained glucose tolerant and insulin sensitive, with increased phosphorylated-AMP-activated protein kinase (P < .05). n-6 group developed hepatic steatosis with reduced hepatic reflected as higher plasma microRNA-122 (P < .04) that targets pAMPK. We conclude that early life exposure to n-6 and n-3 led to hypothalamic AgRP-related higher food intake, with n-6 culminating in a fatty liver partially mitigated by postnatal n-3. While both diets preserved glucose tolerance and insulin sensitivity, postnatal n-3 displayed detrimental effects on the brain.

RESUMO

BACKGROUND: We performed this meta-analysis to assess the efficacy and safety of Jianpi Liqi therapy (JLT), a traditional Chinese medicine therapy, in treating functional dyspepsia (FD). METHODS: We systematically searched 13 databases from their inception to 15th, May 2019. Eligible studies were randomized controlled trials (RCTs) that compared JLT medicine with conventional pharmacotherapy (CP) in treating patients with FD. Cochrane Collaboration tool, Review Manager 5.3 and STATA 11.0, GRADE profiler 3.6 were used for evaluating risk of bias, analyzing, and assessing quality of evidence respectively. RESULTS: After exclusions, 15 RCTs including a total of 1451 participants were included for analysis. We found evidence that JLT had better efficacy than CP (domperidone, omeprazole, esomeprazole, mosapride, lansoprazole, compound digestive enzymes, lactasin tablets) for FD (OR 0.34; 95% CI 0.26, 0.45; P < .00001). Moreover, JLT had more improvement on symptoms including abdominal pain, abdominal distention, early satiety, belching, poor appetite, and fatigue compared with CP. In addition, serious adverse events were not observed in treatment courses. CONCLUSION: This meta-analysis suggested that JLT appears to have better efficacy in treating FD compared with CP. It may be an effective and safe therapy option for patients with FD. Though, more large-sample and strictly designed RCTs are needed to confirm our findings.PROSPERO registration number: CRD42019133241.

RESUMO

Objective: The decrease of Elafin is associated with several inflammatory diseases. Exogenous Elafin may be a treatment for IBD. Little data has shown the expression of Elafin in patients of colorectal cancer. Here, we tried to explore Elafin expression in human tissues of colorectal cancer. Methods: We examined the protein expression of Elafin in human tissues of adjacent nontumor and colorectal tumor by immunohistochemistry (IHC) or quantitative real-time polymerase chain reaction (qRT-PCR), then analyzed the clinical and RNA-seq data presented in The Cancer Genome Atlas (TCGA) database to confirm the relationship between Elafin levels and colorectal tumor. Results: Of the 88 paired samples, 68 colorectal cancer tissues indicated a high expression of Elafin compared with 52 matched adjacent noncancerous tissues. And the mRNA levels of Elafin in 35 paired tissues showed a similar trend. The RNA-seq and clinical data were available in 438 colorectal cancer tissues and 41 normal tissues in TCGA database. The RNA-seq data showed that Elafin mRNA was upregulated about twofold in colorectal cancer samples as compared to adjacent noncancerous samples (176.42 ± 402.13 vs. 96.75 ± 150.07; P = 0.208). No statistically significant correlation was found between the Elafin expression and the age, gender, tumor invasive stage, lymph node metastasis, and distant metastasis both at the protein and mRNA levels. However, the Elafin expression was correlated with clinical stage based on the AJCC guidelines at protein levels but not mRNA levels. Conclusions: Elafin was upregulated in patients of colorectal cancer, resulting to potential limitations for exogenous Elafin treatment.

RESUMO

As we reported in our previous studies, TMTP1, a tumor-homing peptide, selectively targets highly metastatic tumors and their metastatic foci. Aminopeptidase P2 (XPNPEP2) is a receptor for TMTP1 tumor-homing peptide. However, the biological and clinical significance of Aminopeptidase P2 in human cancers remains unknown. In this study, the high-density multiple organ tumor tissue array was employed for the analysis of XPNPEP2 expression profiles in human specimens. The results showed that XPNPEP2 was moderately expressed in the normal prostate tissues, but significantly decreased in the prostate cancer. Hence we used TCGA, IHC, and ELISA to further analyze the expression of XPNPEP2 in tissues and serum of prostate cancer patients. In general, XPNPEP2 expression was lower in prostate cancer tissue than in normal prostate tissue, but was higher in prostate cancer tissues with local invasion and LN metastasis than in tissues with localized Pca. Western blot clarified XPNPEP2 had a secreted form in the serum. Then the serums of 128 Pca patients, 70 healthy males and 40 prostate hyperplasia patients were obtained for detecting serum XPNPEP2 levels.The results indicated that the concentration of XPNPEP2 in serums of Pca patients with LN metastasis (142.7 ± 14.40 ng/mL) were significantly higher than levels in Pca patients without LN metastasis (61.63 ± 5.50 ng/mL) (p < 0.01). An ROC analysis revealed that the combination of PSA and XPNPEP2 was more efficient than PSA or XPNPEP2 alone for predicting LN metastasis, especially for Pca patients with low serum PSA levels. In summary, serum XPNPEP2 levels when combined with PSA levels may result in increased sensitivity for predicting LN metastasis in Pca patients, especially for patients with low serum PSA levels.

RESUMO

To investigate the effect of high-order aberrations (HOAs) on pattern-reversal visual evoked potentials (PR-VEPs), we measured PR-VEPs with HOAs either retained or corrected with an adaptive optics (AO) system for 12 subjects. The PR-VEPs at different spatial frequencies were recorded for the dominant eye of each subject. The results indicated that the amplitude of the first positive P1 wave at 1-16 cpd (except 2 cpd) and the second negative N2 wave at 12 and 16 cpd were raised statistically significantly with HOA correction. This confirmed the contributions of the HOAs to the alterations in PR-VEPs, and suggested that HOAs should be corrected to realize accurate PR-VEP testing.

RESUMO

BACKGROUND: To systematically evaluate efficacy of traditional Chinese medicine (TCM) in treating chronic gastritis (CG). METHODS: Data sources from PubMed, Embase, Springer Link, China National Knowledge Infrastructure, Chinese Scientific Journals Database, Chinese Biomedicine Database, and Wan-fang database were searched up to July 5, 2018. Review Manager software version 5.3, the Cochrane Collaboration's risk of bias tool, and the Grading of Recommendations Assessment, Development, and Evaluation profiler software were conducted for this meta-analysis. RESULTS: Sixteen studies involving 1673 participants (906 vs 767) were included in this study. Pooled data showed significant statistical differences between TCM groups and current routine pharmacotherapy (RP) groups in overall clinical efficacy (odds ratio [OR] 4.65; 95% confidence interval [CI] 3.29, 6.56; P < .00001), efficacy under endoscopy (OR 2.46; 95% CI 1.12, 5.43; P = .03), stomach distension (mean difference [MD] -0.37; 95% CI -0.56, -0.19; P < .0001), stomachache (standardized MD [SMD] -0.80; 95% CI -1.45, -0.14; P = .02), and belching (SMD -2.00; 95% CI -3.80, -0.20; P = .03). However, acid regurgitation (SMD -0.71; 95% CI -1.69, 0.28; P = .16) and anorexia (SMD -0.75; 95% CI -2.30, 0.80; P = .35) showed no significant statistical differences between 2 groups. In addition, incidence of adverse reactions of TCM groups was lower than that of RP groups. CONCLUSION: Evidence from this meta-analysis suggests that TCM could be more efficacious than current RP in treating CG. But further standardized research of rigorous design should be needed to further validate its efficacy.

RESUMO

The health food industry is an important support for the big health industry and the strategy of healthy China. The Chinese medicine prescription health food has exceeded 60% of the total declared health food. However,the main basis for its function evaluation,the Technical Specification for Inspection and Evaluation of Health Food,was abolished in 2018,and 27 of them were based on modern medical and nutritional theories. Quantitative efficacy evaluation methods in western pharmacology are short of function claims and function evaluation methods reflecting the characteristics of traditional Chinese medicine,which could affect the health food industry to a certain extent. Therefore,the establishment of the evaluation mechanism of Chinese medicine prescription health food which conforms to the positioning of health food and the theory of traditional Chinese medicine is helpful for the healthy development of health food industry. In this paper,this problem was explained from five aspects. First,how to differentiate the positioning of Chinese medicine prescription health food from ordinary food and medicine,and how to embody the characteristics of Chinese medicine. Secondly,the relationship between traditional Chinese medicine prescription health food and Chinese patent medicine. Thirdly,how to scientifically and reasonably determine the raw materials of traditional Chinese medicine prescription health food. Fourthly,how to explain the function claim of traditional Chinese medicine prescription health food,and how to evaluate its function scientifically and reasonably. Fifthly,the functional evaluation of Chinese herbal medicine prescription health food is connected with other national scientific and technological strategies. In this paper,a preliminary analysis of the Chinese medicine prescription health food was conducted from the above five aspects,and some personal views and suggestions were put forward,hoping to provide reference for the competent authorities and researchers.

RESUMO

Health food containing Chinese materia medica has many advantages in health preservation and reducing the risk of disease occurrence,which meets people's demands for " great health" and " preventive treatment of disease". However,due to its complex ingredients,diverse quality of raw materials,as well as the vagueness and lack of integrity for existing quality standards,chaos is caused in the health food market,which restricts its healthy development and also poses new challenges to the quality control of healthy food. At present,the total component content or single component content is determined in most functional/marker component examinations. Safety and microbial detection methods fail to cover the contamination range of the raw materials of Chinese materia medica.Therefore,it is impossible to meet the purpose of ensuring authenticity,safety and efficacy. In recent years,a lot of Chinese materia medica extracts have been used as raw materials for food products,but many extracts lack standards. The author believes that the quality control of health food containing Chinese materia medicas should start with the quality control of Chinese materia medica extracts. In this way,product quality is controlled from source to ensure product consistency; secondly,the overall quality control should be strengthened to ensure the authenticity of the products; the scope of safety inspection shall be expanded to fundamentally ensure the safety of products. At the same time,we should strengthen the quality control of whole process and strengthen the overall quality control of raw materials to produce health food of high quality.
