ABSTRACT

Dolomiaea plants are perennial herbs in the Asteraceae family with a long medicinal history. They are rich in chemical constituents, mainly including sesquiterpenes, phenylpropanoids, triterpenes, and steroids. The extracts and chemical constituents of Dolomiaea plants have various pharmacological effects, such as anti-inflammatory, antibacterial, antitumor, anti-gastric ulcer, hepatoprotective and choleretic effects. However, there are few reports on Dolomiaea plants. This study systematically reviewed the research progress on the chemical constituents and pharmacological effects of Dolomiaea plants to provide references for the further development and research of Dolomiaea plants.

ABSTRACT

Radiation-induced intestinal damage (RIID) is a serious disease with limited effective treatment. Nuclear explosion, nuclear release, nuclear application and especially radiation therapy are all highly likely to cause radioactive intestinal damage. The intestinal microecology is an organic whole with a symbiotic relationship formed by the interaction between a relatively stable microbial community living in the intestinal tract and the host. Imbalance and disorders of intestinal microecology are related to the occurrence and development of multiple systemic diseases, especially intestinal diseases. Increasing evidence indicates that the gut microbiota and its metabolites play an important role in the pathogenesis and prevention of RIID. Radiation leads to gut microbiota imbalance, including a decrease in the number of beneficial bacteria and an increase in the number of harmful bacteria that cause RIID. In this review, we describe the pathological mechanisms of RIID, the changes in intestinal microbiota, the metabolites induced by radiation, and their mechanism in RIID. Finally, the mechanisms of various methods for regulating the microbiota in the treatment of RIID are summarized.

ABSTRACT

Chinese medicine processing is a procedure to process medicinal materials under the guidance of traditional Chinese medicine(TCM) theories by using unique methods in China. The medicinal materials can only be used clinically after proper processing. With the development of the modernization of TCM, it is difficult to solve the problems in the inheritance, development, and internationalization of Chinese medicine processing. Metabonomics, a new omics technology developed at the end of the last century, is used to infer the physiological or pathological conditions of the organism with the methods such as NMR and LC-MS via investigating the changes in endogenous small molecule metabolic network after the organism is stimulated by external environment. Metabonomics coincides with the holistic view of TCM because it displays the characteristics of integrity, comprehensiveness, and dynamics, and it has been widely applied in the field of Chinese medicine processing in recent years. This study summarized the application of metabonomics in the processing mechanism and quality control of Chinese medicine processing and prospected the development of this technology in the field of Chinese medicine processing.

ABSTRACT

Syndrome is a nonlinear "internal-excess external-deficiency", "dynamic spatial-temporal" and "multi-dimensional" complex system and thus only by using a versatile method can the connotation be expounded. Metabonomics, which is dynamic, holistic, and systematic, is consistent with the overall mode of traditional Chinese medicine(TCM)(holistic view and syndrome differentiation and treatment). Therefore, metabonomics is very important for the research on the differentiation, material basis, and metabolic pathways of syndromes, and efficacy on syndromes. This study reviewed the application of metabonomics in the study of TCM syndromes in recent years, which is expected to objectify the research on TCM syndromes.

ABSTRACT

Acyclovir (ACV) is an effective and selective antiviral drug, and the study of its toxicology and the use of appropriate detection techniques to control its toxicity at safe levels are extremely important for medicine efforts and human health. This review discusses the mechanism driving ACV's ability to inhibit viral coding, starting from its development and pharmacology. A comprehensive summary of the existing preparation methods and synthetic materials, such as 5-aminoimidazole-4-carboxamide, guanine and its derivatives, and other purine derivatives, is presented to elucidate the preparation of ACV in detail. In addition, it presents valuable analytical procedures for the toxicological studies of ACV, which are essential for human use and dosing. Analytical methods, including spectrophotometry, high performance liquid chromatography (HPLC), liquid chromatography/tandem mass spectrometry (LC-MS/MS), electrochemical sensors, molecularly imprinted polymers (MIPs), and flow injection-chemiluminescence (FI-CL) are also highlighted. A brief description of the characteristics of each of these methods is also presented. Finally, insight is provided for the development of ACV to drive further innovation of ACV in pharmaceutical applications. This review provides a comprehensive summary of the past life and future challenges of ACV.

ABSTRACT

BACKGROUND: Homozygous or compound heterozygous mutations in high temperature requirement serine peptidase A1 (HTRA1) gene are responsible for cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL). Recently, increasing evidence has shown that heterozygous HTRA1 mutations are also associated with cerebral small vessel disease (CSVD) with an autosomal dominant pattern of inheritance. This study was aimed to analyze the genetic and clinical characteristics of HTRA1-related autosomal dominant CSVD. METHODS: We presented three new Chinese cases of familial CSVD with heterozygous HTRA1 mutations and reviewed all clinical case reports and articles on HTRA1-related autosomal dominant CSVD included in PUBMED by the end of March 1, 2020. CARASIL probands with genetic diagnosis reported to date were also reviewed. The genetic and clinical characteristics of HTRA1-related autosomal dominant CSVD were summarized and analyzed by comparing with CARASIL. RESULTS: Forty-four HTRA1-related autosomal dominant CSVD probands and 22 CARASIL probands were included. Compared with typical CARASIL, HTRA1-related autosomal dominant probands has a higher proportion of vascular risk factors (P < 0.001), a later onset age (P < 0.001), and a relatively slower clinical progression. Alopecia and spondylosis can be observed, but less than those in the typical CARASIL. Thirty-five heterozygous mutations in HTRA1 were reported, most of which were missense mutations. Amino acids located close to amino acids 250-300 were most frequently affected, followed by these located near 150∼200. While amino acids 250∼300 were also the most frequently affected region in CARASIL patients, fewer mutations precede the 200th amino acids were detected, especially in the Kazal-type serine protease domain. CONCLUSIONS: HTRA1-related autosomal dominant CSVD is present as a mild phenotype of CARASIL. The trend of regional concentration of mutation sites may be related to the concentration of key sites in these regions which are responsible for pathogenesis of HTRA1-related autosomal dominant CSVD.

ABSTRACT

The Brassica rapa (B. rapa) species displays enormous phenotypic diversity, with leafy vegetables, storage root vegetables and oil crops. These different crops all have different flowering time, which determine their growing season and cultivation area. Little is known about the effects of diverse temperature and day-lengths on flowering time QTL associated with FLC paralogues. We phenotyped the flowering time of a doubled haploid population, established from a cross between Yellow sarson and Pak choi under diverse environmental conditions. We identified flowering-time QTL (fQTL) in different photoperiod and temperature regimes in the greenhouse, and studied their colocation with known flowering time genes. As several fQTL colocalized with FLC paralogues, we studied the expression patterns of four FLC paralogues during the course of vernalization in parental lines. Under all environmental conditions tested the major fQTL that mapped to the BrFLC2_A02 locus was detected, however its effect decreased when plants were grown at low temperatures. Another fQTL that mapped to the FLC paralogue, BrFLC5_A03 was also identified under all tested environments, while no fQTL colocated with BrFLC1_A10 or BrFLC3_A03. Furthermore, the vernalization treatment decreased expression of all BrFLC paralogues in the parental lines, and showed the lowest transcript level after 28 days of vernalization. Transcript abundance stayed low after returning the plants for seven days to normal growth temperature. Interestingly, transcript abundance of BrFLC3_A03 and BrFLC5_A03 was repressed much stronger and already reached lowest levels after 14d in the early-flowering type YS-143. This study improves understanding of the effects of daylength and vernalization on flowering time in B. rapa and the role of the different BrFLC paralogues therein.

ABSTRACT

BACKGROUND/AIMS: Current practical advances in high-throughput data technologies including RNA-sequencing have led to the identification of long non-coding RNAs (lncRNAs) for potential clinical application against bladder urothelial cancer (BLCA). However, most previous studies focused on the clinical value of individual lncRNAs, which has limited the potential for future clinical application. METHODS: In this study, RNA-sequencing data of lncRNAs was downloaded from The Cancer Genome Atlas database. Risk score was constructed based on survival-associated lncRNAs identified using differential expression analysis as well as univariate and multivariate Cox proportional hazards regression analysis. Receiver operating characteristic and Kaplan-Meier curve analyses were employed to evaluate the clinical and prognostic value of risk scores. Bioinformatics analyses were used to investigate the potential mechanisms of newly identified lncRNAs. RESULTS: Among 2,127 differentially expressed lncRNAs (DELs), four new lncRNAs (AC145124.1, AC010168.2, MIR200CHG, and AC098613.1) showed valuable prognostic effects in BLCA patients. More importantly, the four-DEL-based risk score had the potential to become an independent marker for the survival status prediction of BLCA patients. Distinct co-expressed genes and signaling pathways were identified when BLCA was categorized into low- and high-risk groups. Furthermore, a protein-coding gene, HIST4H4 was found only 68 bp from the AC010168.2 DEL. HIST4H4 expression level was evidently up-regulated and positively correlated with AC010168.2 in BLCA patients. CONCLUSION: This in silico investigation pioneers the future investigation of the utility of prognostic lncRNAs for BLCA.

ABSTRACT

Matrine, one of the main alkaloid components extracted from the traditional Chinese herb, Sophora flavescens Ait, has various pharmacological effects, and has been reported to exert antitumor activity in melanoma. In the current study, the molecular mechanisms underlying the inhibitory effects of matrine were investigated in melanoma cell line. It was initially confirmed that matrine inhibited proliferation, invasion and induced apoptosis in human A375 and SK-MEL-2 melanoma cell lines in vitro. Subsequently, reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis demonstrated that the expression of microRNA (miR)-19b-3p was significantly increased in melanoma cells and was downregulated by treatment with matrine. Furthermore, downregulated miR-19b-3p exerted effects similar to 500 µg/ml matrine on cell proliferation, invasion and apoptosis. Phosphatase and tensin homolog (PTEN) mRNA was identified as a direct target of miR-19b-3p through bioinformatics analysis and a dual-luciferase reporter assay. Additionally, western blotting and RT-qPCR analysis demonstrated that the expression of PTEN protein and mRNA were increased by the treatment with matrine. Furthermore, silencing of PTEN expression reversed the effects of matrine and miR-19b-3p downregulation in A375 and SK-MEL-2 cells. Taken together, the results indicated that matrine may suppress cell proliferation and invasion and induce cell apoptosis partially via miR-19b-3p targeting of PTEN.

ABSTRACT

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) has been reported to have effects on kidney diseases; however, a link between NAFLD and urinary calculi remains to be confirmed. This study was conducted on a male population based on our previous Fangchenggang Area Male Health and Examination Survey in Guangxi, China in order to estimate the frequency of urinary calculi and assess the association between NAFLD and urinary calculi while controlling for possible confounders. MATERIALS AND METHODS: This was a population-based cross-sectional study conducted in the Fangchenggang region in Guangxi, China. The diagnoses of NAFLD and urinary calculi were made by ultrasonography. Clinical and laboratory findings were analyzed to investigate whether NAFLD was a risk factor for urinary calculi. RESULTS: A total of 3719 men were enrolled (age range, 17 to 88 years). Slightly more than a quarter (26.5%) of the participants were diagnosed with NAFLD. The percentage of urinary calculi in all participants was 6.9%, and the percentage of NAFLD patients with urinary calculi (8.4%) was significantly higher than that among patients without NAFLD (6.4%, P < .05). Advanced age; high body mass index; elevated levels of blood glucose, cholesterol, triglycerides, and low-density lipoprotein cholesterol; low education; lower or higher physical activity; and NAFLD were independent risk factors for urinary calculi (P < .05). CONCLUSIONS: Our results showed that NAFLD was associated with a higher incidence of urinary calculi in this cohort and NAFLD might represent a risk factor for urinary calculi.

ABSTRACT

Non-heading Chinese cabbage (Brassica rapa ssp. chinensis) is one of the main green leafy vegetables in the world, especially in China, with significant economic value. Hyaloperonospora parasitica is a fungal pathogen responsible for causing downy mildew disease in Chinese cabbage, which greatly affects its production. The objective of this study was to identify transcriptionally regulated genes during incompatible interactions between non-heading Chinese cabbage and H. parasitica using complementary DNA-amplified fragment length polymorphism (cDNA-AFLP). We obtained 129 reliable differential transcript-derived fragments (TDFs) in a resistant line 'Suzhou Qing'. Among them, 121 upregulated TDFs displayed an expression peak at 24-48 h post inoculation (h.p.i.). Fifteen genes were further selected for validation of cDNA-AFLP expression patterns using quantitative reverse transcription PCR. Results confirmed the altered expression patterns of 13 genes (86.7%) revealed by the cDNA-AFLP. We identified four TDFs related to fungal resistance among the 15 TDFs. Furthermore, comparative analysis of four TDFs between resistant line 'Suzhou Qing' and susceptible line 'Aijiao Huang' showed that transcript levels of TDF14 (BcLIK1_A01) peaked at 48 h.p.i. and 25.1-fold increased in the resistant line compared with the susceptible line. Similarly, transcript levels of the other three genes, TDF42 (BcCAT3_A07), TDF75 (BcAAE3_A06) and TDF88 (BcAMT2_A05) peaked at 24, 48 and 24 h.p.i. with 25.1-, 100- and 15.8-fold increases, respectively. The results suggested that the resistance genes tended to transcribe at higher levels in the resistance line than in the susceptible line, which may provide resistance against pathogen infections. The present study might facilitate elucidating the molecular basis of the infection process and identifying candidate genes for resistance improvement of susceptible cultivars.

ABSTRACT

UNLABELLED: In Chinese cabbage, leafy head-related traits are directly related to the cabbage yield and marketability, which are often primarily concerned target for breeders. Although intensive studies has been on head formation in Chinese cabbage in the past decade, very scanty information is available on mechanism involved in the head formation under the influence of low temperature at transcriptome and proteome perspective. In this study, quantitative expression profiling based on RNA-Seq transcriptome and iTRAQ proteome were combined to investigate this trait for a global picture of the molecular dynamics. Total of 2931 transcripts and 365 proteins were identified with significantly changed level in abundance from heading and non-heading Chinese cabbage. Related analyses including function annotations, hierarchical categories, as well as the correlation from transcript-to-proteins were performed. The results indicated that the leafy head formation of Chinese cabbage has involved a complex regulatory pattern. The correlated genes that were mapped to the pathway of plant hormone signal transduction suggested that the head formation might be an integrated result of various plant hormones. Our combined analysis will provide a comprehensive approach to understanding the regulation mechanism of leafy head formation in Chinese cabbage. BIOLOGICAL SIGNIFICANCE: This study revealed the direct relation of leafy-heading traits with the yield of the plant. A comprehensive investigation was done by integrating quantitative expression profiling analysis of transcriptome and proteomic to provide crucial information for further research on the molecular mechanism involved in head formation in Chinese cabbage. The correlation of transcript-to-protein in abundance may afford some necessary information of involvement of post-transcriptional factors influencing leafy head formation in Chinese cabbage.

ABSTRACT

AIMS AND OBJECTIVES: This study aimed to investigate the effects of a feeding intervention in patients with Alzheimer's disease with dysphagia. BACKGROUND: In patients with Alzheimer's disease, inadequate food and fluid intake can result in malnutrition, dehydration and increased morbidity and mortality. Patients may lose self-care abilities such as self-feeding. DESIGN: A prospective cohort study. METHODS: A three-month self-control feeding intervention was conducted prospectively in 30 nursing home residents with Alzheimer's disease with dysphagia. Pre- and post-intervention measures included the Kubota water swallow test, type and amount of food intake and assessment of nutritional status by triceps skinfold thickness, upper arm circumference, serum albumin and haemoglobin. We used the Edinburgh Feeding Evaluation in Dementia scale to evaluate eating compliance and the Mini- Mental State Examination to evaluate cognitive function. Pre- and post-intervention results were compared to evaluate the effects of nursing intervention. RESULTS: Patients' eating/feeding abilities improved overall, including significantly increased food intake (p < 0·001), decreased levels on the Kubota water swallow test (p < 0·001) and significant differences in skinfold thickness, arm circumference, serum albumin and haemoglobin (all p < 0·01), indicating improved nutritional status. Edinburgh Feeding Evaluation in Dementia scale scores decreased significantly, showing improved eating compliance. No changes were noted in cognition post-intervention. Among 22 patients who initially required feeding, five patients resumed self-feeding after the intervention (p = 0·06). CONCLUSIONS: Results of this study show that a feeding intervention can improve food intake, eating compliance and nutritional status in patients with Alzheimer's disease with dysphagia and prevent further decline in swallowing function. RELEVANCE TO CLINICAL PRACTICE: The significant improvement in eating/feeding measures suggest that this feeding intervention model could be developed as a feeding skills programme to improve both the eating/feeding care by nursing staff and the eating/feeding abilities and nutritional status of Alzheimer's disease patients.

ABSTRACT

The global prevalence of weight loss is increasing, especially in young women. However, the extent and mechanisms by which maternal weight loss affects the offspring is still poorly understood. Here, using an enriched environment (EE)-induced weight loss model, we show that maternal weight loss improves general health and reprograms metabolic gene expression in mouse offspring, and the epigenetic alterations can be inherited for at least two generations. EE in mothers induced weight loss and its associated physiological and metabolic changes such as decreased adiposity and improved glucose tolerance and insulin sensitivity. Relative to controls, their offspring exhibited improved general health such as reduced fat accumulation, decreased plasma and hepatic lipid levels, and improved glucose tolerance and insulin sensitivity. Maternal weight loss altered gene expression patterns in the liver of offspring with coherent down-regulation of genes involved in lipid and cholesterol biosynthesis. Epigenomic profiling of offspring livers revealed numerous changes in cytosine methylation depending on maternal weight loss, including reproducible changes in promoter methylation over several key lipid biosynthesis genes, correlated with their expression patterns. Embryo transfer studies indicated that oocyte alteration in response to maternal metabolic conditions is a strong factor in determining metabolic and epigenetic changes in offspring. Several important lipid metabolism-related genes have been identified to partially inherit methylated alleles from oocytes. Our study reveals a molecular and mechanistic basis of how maternal lifestyle modification affects metabolic changes in the offspring.

ABSTRACT

OBJECTIVE: To diagnose muscular dystrophy using Western blot (WB) by improving the method of the protein extraction. METHOD: Firstly,we compared the effect of different sample buffer solutions and processing Methods on the extraction of muscle protein in rats,then selected the appropriate extracting method and the process of the muscular protein. RESULTS: We put the selected sample buffer into the micro-sample,then mixed. The concentration of the extracting protein was much more,and the loss during the process was much less. We extracted enough protein in 62 cases. The protein bands were showed clearly by WB,and the abnormal protein bands were shown in some patients. Compared with the Results of immunohistochemical staining detected the severe abnormal expressions of Dys-R,Dys-C,and Dys-N in the specimens,we did not detect the corresponding target band in WB. We detected the target protein band of the specimens were abnormal position,light or normal staining in WB,while Dys were mildly expressed in immunohistochemical staining. CONCLUSIONS: The improved protein extraction method can save the muscle tissue,and the protein bands can be used for diagnosing the muscular dystrophy. For clinically suspected patients with dystrophinopathy,if normal or mild deficiency is shown by immunohistochemistry,WB should be applied to detect the dystrophin protein band.

ABSTRACT

OBJECTIVE: The aim of this study was to describe the clinical and radiological findings of patients with moyamoya syndrome and Graves' disease. Possible mechanisms predisposing these individuals to ischemic stroke are discussed. METHODS: We retrospectively analyzed 12 consecutive patients with both moyamoya syndrome and Graves' disease. Moyamoya vasculopathy was diagnosed by digital subtract angiography or magnetic resonance angiography (MRA). The clinical characteristics, laboratory data, vascular radiological characteristics and outcome were reported. RESULTS: All patients were female and mean age was 33.33±12.65 years. Stenosis or occlusion of bilateral terminal internal carotid artery and/or proximal anterior/middle cerebral arteries was found in nine patients. Among them, three patients displayed asymmetrical stenosis. In addition, there were three patients with probable unilateral moamoya syndrome. Eleven patients presented with ischemic stroke and/or transient ischemic attack (TIA) and one with dizziness. Thyroid function tests demonstrated elevated thyroid hormone levels and suppressed thyroid stimulating hormone levels in all the patients with ischemic events. All patients received anti-thyroid therapy and two had recurrent ischemic attack after drug withdrawal. CONCLUSIONS: Moyamoya syndrome associated Graves' disease often presented with asymmetric stenosis or occlusion. We hypothesize cerebrovascular hemodynamic changes due to thyrotoxicosis contribute to the ischemic events.

ABSTRACT

The global prevalence of prediabetes and type 2 diabetes (T2D) is increasing, and it is contributing to the susceptibility to diabetes and its related epidemic in offspring. Although the impacts of paternal impaired fasting blood glucose and glucose intolerance on the metabolism of offspring have been well established, the exact molecular and mechanistic basis that mediates these impacts remains largely unclear. Here we show that paternal prediabetes increases the susceptibility to diabetes in offspring through gametic epigenetic alterations. In our findings, paternal prediabetes led to glucose intolerance and insulin resistance in offspring. Relative to controls, offspring of prediabetic fathers exhibited altered gene expression patterns in the pancreatic islets, with down-regulation of several genes involved in glucose metabolism and insulin signaling pathways. Epigenomic profiling of offspring pancreatic islets revealed numerous changes in cytosine methylation depending on paternal prediabetes, including reproducible changes in methylation over several insulin signaling genes. Paternal prediabetes altered overall methylome patterns in sperm, with a large portion of differentially methylated genes overlapping with that of pancreatic islets in offspring. Our study uniquely revealed that prediabetes can be inherited transgenerationally through the mammalian germ line by an epigenetic mechanism.

ABSTRACT

OBJECTIVE: To observe the anti-atherosclerotic effect and its possible mechanisms of Modified Zhenzhu Tiaozhi Capsule (MZTC) in rabbits. METHODS: 50 rabbits were divided into five groups, i.e., the normal group, the model group, the simvastatin group (3 mg/kg), the high dose MZTC group (1.6 g crude drug/kg), and the low dose MZTC group (1.6 g crude drug/kg), respectively, ten in each group. The atherosclerosis (AS) model was established by feeding rabbits with high fat diet. Corresponding medicines were administrated on the basis of high fat diet for twelve successive weeks. Levels of blood lipids, serum superoxide dismutase (SOD), malondialdehyde (MDA), and nitric oxide (NO) were detected. The area of the aortic tunica intima plaque was determined. The pathological changes of the aorta were observed. RESULTS: Compared with the model group, serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), MDA, and atherosclerotic index (AI) were significantly lowered in the MZTC groups (P<0.05, P<0.01), while serum levels of high-density lipoprotein cholesterol (HDL-C), SOD, and NO obviously increased (P<0.05, P<0.01). Serum levels of TC, TG, LDL-C, and in the MZTC groups were obviously higher than those of the simvastatin group (P<0.01), and there was insignificant difference in other indices. The ratio of the aortic tunica intima plaque percentage to the total tunica intima area was also markedly lower than that of the model group (P<0.05, P<0.01). Results under light microscope indicated the pathological changes of the aorta was obviously attenuated. CONCLUSIONS: MZTC could inhibit the formation and development of AS plaque. Its mechanism might be associated with regulating lipids metabolism, antioxidation, and improving endothelial functions.

Common synthetic dyes, e.g., Weak Acid Pink Red B (APRB, C.I. 18073), Mordant Blue 9 (MB, C.I.14855) and Acid Brilliant Blue 6B (ABB6B, C.I. 42660), can be removed from water by in situ hybridization with CaCO(3), BaSO(4) and Ca(3)(PO(4))(2) and the resulting hybrids thus prepared used as plastic colorants. All the hybrids can be processed into polypropylene (PP) at 200 °C with good color intensity, color brightness and homogeneous dispersion. The BaSO(4)-MB hybrid exhibits better migration resistance to acid and alkali, and stronger covering power than the BaSO(4)-MB mixture. The thermal stability and UV resistance of the Ca(3)(PO(4))(2)-ABB6B hybrid are better than those of the Ca(3)(PO(4))(2)-ABB6B mixture. The crystallinity of PP is enhanced by incorporation of these hybrids and the use of these hybrids as colorants in PP instead of the dyes alone is determined to be feasible.
