ABSTRACT

Four new prenylflavonoid glycosides, namely koreanoside H-K (1-4), together with eleven known ones (5-15) were isolated from the leaves of Epimedium koreanum Nakai. Their structures were elucidated by 1D NMR, 2D NMR, HR-ESI-MS, IR and UV. The identification of the sugar moieties was carried out by means of acid hydrolysis and HPLC analysis of their derivatives. It is worth noting that compound 3 and compound 4 were elucidated to contain fucose and quinovose moieties, which were two extremely rare sugar units from the genus Epimedium. The anti-pulmonary fibrosis activity of the new compounds was evaluated using A549 cell line. Compounds 1, 2 and 4 showed significant anti-pulmonary fibrosis activities.

ABSTRACT

The association among plasma trimethylamine-N-oxide (TMAO), FMO3 polymorphisms, and chronic heart failure (CHF) remains to be elucidated. TMAO is a microbiota-dependent metabolite from dietary choline and carnitine. A prospective study was performed including 955 consecutively diagnosed CHF patients with reduced ejection fraction, with the longest follow-up of 7 years. The concentrations of plasma TMAO and its precursors, namely, choline and carnitine, were determined by liquid chromatography-mass spectrometry, and the FMO3 E158K polymorphisms (rs2266782) were genotyped. The top tertile of plasma TMAO was associated with a significant increment in hazard ratio (HR) for the composite outcome of cardiovascular death or heart transplantation (HR = 1.47, 95% CI = 1.13-1.91, P = 0.004) compared with the lowest tertile. After adjustments of the potential confounders, higher TMAO could still be used to predict the risk of the primary endpoint (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). This result was also obtained after further adjustment for carnitine (adjusted HR = 1.33, 95% CI = 1.01-1.74, P = 0.039). The FMO3 rs2266782 polymorphism was associated with the plasma TMAO concentrations in our cohort, and lower TMAO levels were found in the AA-genotype. Thus, higher plasma TMAO levels indicated increased risk of the composite outcome of cardiovascular death or heart transplantation independent of potential confounders, and the FMO3 AA-genotype in rs2266782 was related to lower plasma TMAO levels.

ABSTRACT

At present, there have been many clinical trials and systematic reviews/Meta-analysis proving the good clinical efficacy of Shufeng Jiedu Capsules in the treatment of respiratory diseases, while comprehensive discussion is still required. This article overviews and analyzes the systematic reviews/Meta-analysis of Shufeng Jiedu Capsules to provide evidence support for clinical practice. The systematic reviews/Meta-analysis of Shufeng Jiedu Capsules were searched from CBM, Wanfang, CNKI, VIP, PubMed, EMbase and Cochrane Library. The AMSTAR 2 scale and GRADE system were respectively employed for the evaluation of methodological quality and the grading of evidence quality. Finally, 8 systematic reviews/Meta-analysis published during 2018-2021 were included for analysis. The diseases involved include acute exacerbation of chronic obstructive pulmonary disease, community-acquired pneumonia, acute tonsillitis, acute exacerbation of chronic bronchitis and acute upper respiratory tract infection. The number of included RCTs studies ranged from 8 to 25. The results showed that Shufeng Jiedu Capsules combined with western medicine routine had better therapeutic effect than the latter alone in the treatment of the above five diseases. The reported adverse reactions caused by Shufeng Jiedu Capsules were mainly gastrointestinal discomforts such as mild nausea, diarrhoea and vomiting, with low incidence and mild symptoms, which can be relieved by drug withdrawal. The methodological quality of the included studies was extremely low, and the outcome indicators were mainly of low and very low grades. The efficacy and safety of Shufeng Jiedu Capsules in the clinical treatment of diseases still need to be verified based on more high-quality studies. The relevant clinical research and systematic review/Meta-analysis should pay more attention to methodological quality and reporting standards and strengthen the scientificity of research.

ABSTRACT

Objective: To investigate the effect of Xuanfu Daizhe decoction on the stemness of esophageal cancer cells. Methods: The BALB/c nude mice were randomly divided into the control group and experimental group, 5 mice in each group, which were continuously administered with normal saline and Xuanfu Daizhe decoction (9.89 g/kg) by gastrogavage, respectively. Human esophageal carcinoma cells ECA-109 (5×106) were subcutaneously injected into the mice on the 8th day. Tumor volume was measured twice a week. The mice were sacrificed 4 weeks after injection, and the tumor tissue and mouse serum were collected. The expressions of the major stemness-regulating transcription factors, i.e., NANOG, OCT4 and SOX2, were detected by RT-qPCR, Western Blot and immunohistochemistry. ECA-109 cells were treated with 10% fetal bovine serum and serum from the above two groups of mice for 48 hours respectively, and three replicate wells were set in each group, and the expressions of NANOG, OCT4, SOX2 and the levels of AKT and p-AKT were detected by RT-qPCR and Western Blot, respectively. ALDH activity in tumor cells was detected by flow cytometry; the number of spheroids of tumor cells was detected by the spheroidization experiment. Results: Compared with the control group, the growth and size of esophageal cancer tumors were significantly inhibited by Xuanfu Daizhe Decoction; the expressions of NANOG, OCT4, SOX2, the ALDH activity, the number of spheroids, and the levels of AKT and phosphorylated AKT (p-AKT) in esophageal cancer cells were significantly reduced by Xuanfu Daizhe Decoction both in vivo and in vitro. Conclusion: Xuanfu Daizhe Decoction inhibits the stemness of esophageal cancer cells, it may be a potentially effective drug for the treatment of esophageal cancer and provides a theoretical basis for the exploration of new effective drugs for the treatment of esophageal cancer.

ABSTRACT

As a new CRISPR/Cas-derived genome engineering technology, base editing combines the target specificity of CRISPR/Cas and the catalytic activity of nucleobase deaminase to install point mutations at target loci without generating DSBs, requiring exogenous template, or depending on homologous recombination. Recently, researchers have developed a variety of base editing tools in the important industrial strain Corynebacterium glutamicum, and achieved simultaneous editing of two and three genes. However, the multiplex base editing based on CRISPR/Cas9 is still limited by the complexity of multiple sgRNAs, interference of repeated sequence and difficulty of target loci replacement. In this study, multiplex base editing in C. glutamicum was optimized by the following strategies. Firstly, the multiple sgRNA expression cassettes based on individual promoters/terminators was optimized. The target loci can be introduced and replaced rapidly by using a template plasmid and Golden Gate method, which also avoids the interference of repeated sequence. Although the multiple sgRNAs structure is still complicated, the editing efficiency of this strategy is the highest. Then, the multiple gRNA expression cassettes based on Type Ⅱ CRISPR crRNA arrays and tRNA processing were developed. The two strategies only require one single promoter and terminator, and greatly simplify the structure of the expression cassette. Although the editing efficiency has decreased, both methods are still applicable. Taken together, this study provides a powerful addition to the genome editing toolbox of C. glutamicum and facilitates genetic modification of this strain.

ABSTRACT

Objective@#Neonatal exposure to propofol has been reported to cause neurotoxicity and neurocognitive decline in adulthood; however, the underlying mechanism has not been established.@*Methods@#SD rats were exposed to propofol on postnatal day 7 (PND-7). Double-immunofluorescence staining was used to assess neurogenesis in the hippocampal dentate gyrus (DG). The expression of p-Akt and p27 were measured by western blotting. The Morris water maze, novel object recognition test, and object location test were used to evaluate neurocognitive function 2-month-old rats.@*Results@#Phosphorylation of Akt was inhibited, while p27 expression was enhanced after neonatal exposure to propofol. Propofol also inhibited proliferation of neural stem cells (NSCs) and decreased differentiation to neurons and astroglia. Moreover, the neurocognitive function in 2-month-old rats was weakened. Of significance, intra-hippocampal injection of the Akt activator, SC79, attenuated the inhibition of p-AKT and increase of p27 expression. SC79 also rescued the propofol-induced inhibition of NSC proliferation and differentiation. The propofol-induced neurocognition deficit was also partially reversed by SC79.@*Conclusion@#Taken together, these results suggest that neurogenesis is hindered by neonatal propofol exposure. Specifically, neonatal propofol exposure was shown to suppress the proliferation and differentiation of NSCs by inhibiting Akt/p27 signaling pathway.

ABSTRACT

BackgroundSkeletal muscle is the largest tissue in the human body, and it plays a major role in exerting force and maintaining metabolism homeostasis. The role of muscle transcription factors in the regulation of metabolism is not fully understood. MondoA is a glucose-sensing transcription factor that is highly expressed in skeletal muscle. Previous studies suggest that MondoA can influence systemic metabolism homeostasis. However, the function of MondoA in the skeletal muscle remains unclear.MethodsWe generated muscle-specific MondoA knockout (MAKO) mice and analyzed the skeletal muscle morphology and glycogen content. Along with skeletal muscle from MAKO mice, C2C12 myocytes transfected with small interfering RNA against MondoA were also used to investigate the role and potential mechanism of MondoA in the development and glycogen metabolism of skeletal muscle.ResultsMAKO caused muscle fiber atrophy, reduced the proportion of type II fibers compared to type I fibers, and increased the muscle glycogen level. MondoA knockdown inhibited myoblast proliferation, migration, and differentiation by inhibiting the phosphatase and tensin homolog (PTEN)/phosphoinositide 3-kinase (PI3K)/Akt pathway. Further mechanistic experiments revealed that the increased muscle glycogen in MAKO mice was caused by thioredoxin-interacting protein (TXNIP) downregulation, which led to upregulation of glucose transporter 4 (GLUT4), potentially increasing glucose uptake.ConclusionMondoA appears to mediate mouse myofiber development, and MondoA decreases the muscle glycogen level. The findings indicate the potential function of MondoA in skeletal muscle, linking the glucose-related transcription factor to myogenesis and skeletal myofiber glycogen metabolism.

ABSTRACT

To investigate the molecular mechanism of resveratrol inhibiting the metastasis of liver cancer . HepG2 and Huh7 cells were treated with different concentrations of resveratrol, and the cell viability was determined by CCK-8 assay to determine the optimal concentration of resveratrol for subsequent experiments. The expressions of miR-186-5p in liver cancer tissues and liver cancer cells were determined by quantitative real-time RT-PCR. The migration and invasion of HepG2 and Huh7 cells were detected by wound healing assay and Transwell assay, and the expression levels of epithelial-mesenchymal transition (EMT) related proteins were determined by Western blotting. Resveratrol with concentration of had no effect on the viability of HepG2 and Huh7 cells, so the concentration of resveratrol in subsequent experiments was 6.25 μmol/L. Resveratrol inhibited the wound healing and invasion of liver cancer cells; increased the expression of E-cadherin, and decreased the expression of vimentin and Twist1. The expression of miR-186-5p was significantly down-regulated in liver cancer tissues and cells compared with the adjacent tissues and normal liver cells (both <0.05). Furthermore, resveratrol induced the expression of miR-186-5p in liver cancer cells (both <0.01). Overexpression of miR-186-5p suppressed the migration, invasion and EMT of liver cancer cells. Knockdown of miR-186-5p blocked the inhibition effects of resveratrol on the migration, invasion and EMT of liver cancer cells. Resveratrol could inhibit the metastasis of liver cancer , which might be associated with up-regulating miR-186-5p.

ABSTRACT

BACKGROUND@#The effects of environmental chemical exposure on blood pressure (BP) have been confirmed, but the association between exposure to secondhand smoke (SHS) and hypertension risk and BP in the general population remains unknown.@*METHODS@#Cross-sectional associations between SHS exposure and hypertension risk and BP values were evaluated using data for subjects who participated in the National Health and Nutrition Examination Survey (NHANES), 1999-2016. Logistic regression and linear regression were performed after adjusting for age, sex, race, alcohol consumption, poverty-to-income ratio (PIR), body mass index (BMI), estimated glomerular filtration rate, physical activity, diabetes, cardiovascular disease, and NHANES cycle. Restricted cubic spline models were created to display the potential nonlinear association between SHS and BP levels.@*RESULTS@#Higher risk of hypertension was found at the highest SHS concentrations (OR = 1.13, 95% CI 1.04, 1.24, P for trend = 0.007). Additionally, SHS exposure had a strong positive association with systolic blood pressure (SBP) but was negatively associated with diastolic blood pressure (DBP). Furthermore, the nonlinear model result showed a significant association between SHS and SBP (P = 0.017); however, the nonlinear model result was not significant for SHS or DBP.@*CONCLUSIONS@#Our results suggest a potential association between high SHS exposure and the risk of hypertension. Further research is needed to elucidate the underlying mechanisms.

ABSTRACT

Since December 2019, the novel coronavirus (severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) has spread to many countries around the world, developing into a global pandemic with increasing numbers of deaths reported worldwide. To data, although some vaccines have been developed, there are no ideal drugs to treat novel coronavirus pneumonia (coronavirus disease 2019 (COVID-19)). By examining the structure of the coronavirus and briefly describing its possible pathogenesis based on recent autopsy reports conducted by various teams worldwide, this review analyzes the possible structural and functional changes of the human body upon infection with SARS-CoV-2. We observed that the most prominent pathological changes in COVID-19 patients are diffuse alveolar damage (DAD) of the lungs and microthrombus formation, resulting in an imbalance of the ventilation/perfusion ratio and respiratory failure. Although direct evidence of viral infection can also be found in other organs and tissues, the viral load is relatively small. The conclusion that the injuries of the extra-pulmonary organs are directly caused by the virus needs further investigation.

ABSTRACT

In this study, a composite cell model for evaluation of idiosyncratic drug-induced liver injury (IDILI) was established in vitro from the perspective of immune inflammation. And this model was used to evaluate the risk of IDILI for 2,3,5,4'-tetrahydroxy-cis-stilbene-2-O-β-glucoside (Cis-SG) and 2,3,5,4'-tetrahydroxy-trans-stilbene-2-O-β-glucoside (Trans-SG). To determine the low, medium, and high dosage of Cis-SG and Trans-SG, CellTiter-Glo® 3D Cell Viability Assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of HepG2 cells in three dimensional (3D) culture, and MTT assay was used to detect the effects of Cis-SG and Trans-SG on cell viability of THP-1 derived macrophages. THP-1 derived macrophages were incubated by Cis-SG and Trans-SG directly or supernatants from HepG2 cells incubated with them. Enzyme linked immunosorbent assay (ELISA) was used to detect the levels of interleukin-1β (IL-1β) in the supernatants of the THP-1 derived macrophages. Western blot and reverse transcription-polymerase chain reaction (RT-PCR) were used to determine the expression of apoptosis-associated speck-like protein (ASC), Nod-like receptor protein 3 (NLRP3), cysteinyl aspartate specific proteinase-1 (caspase-1), and IL-1β in THP-1 derived macrophages. The results showed that there was no effect on the secretion of IL-1β in THP-1 derived macrophages incubated by Cis-SG and Trans-SG directly. However, the secretion of IL-1β, the protein and mRNA expression of ASC, NLRP3, caspase-1, and IL-1β significantly increased in THP-1 derived macrophages incubated by supernatants from HepG2 cells incubated with 1, 5, and 25 μmol·L-1 Cis-SG or 25 μmol·L-1 Trans-SG. In summary, the composite cell model for evaluation of IDILI established in vitro has been successfully applied in testing Cis-SG and Trans-SG. This composite cell model is helpful to evaluate and screen drugs with IDILI risk in vitro preliminarily, which provides methods for predicting and solving the idiosyncratic liver toxicity of drugs.

ABSTRACT

Objective:To analyze current situation of hospice care in Jinshan District of Shanghai and provide recommendations for development of hospice care. Methods:This cross-sectional study included 8 hospice care institutions, their health staff and 316 patients during May-August, 2019. Results were analyzed by quantitative and qualitative methods. Results:There had 80 approved beds in Jinshan District, but only 53 beds were used for 189 inpatients in 2017. Hospice care institutions received financial supports from district government at the construction stage, but relied on their own for daily operation costs. The motivation of health staff to work in hospice care was not strong. Among the hospice care workers, 18% had no certification for hospice care, and only 5% of them had senior professional titles. Continued education for health workers in hospice care was weak and the workers were under heavy stress. Conclusion:The potential needs for hospice care were unmet while hospice care was under-utilization in Jinshan District. The development of hospice care was unbalanced, and the health workers lacked motivation. The resources of hospice care need to be strengthened.
