ABSTRACT

Objective: To explore the relationship between low density lipoprotein cholesterol (LDL-C)/high density lipoprotein cholesterol (HDL-C) ratio with the severity of coronary artery disease and 2-yeat outcome in patients with premature coronary heart disease. Methods: This prospective, multicenter, observational cohort study is originated from the PROMISE study. Eighteen thousand seven hundred and one patients with coronary heart disease (CHD) were screened from January 2015 to May 2019. Three thousand eight hundred and sixty-one patients with premature CHD were enrolled in the current study. According to the median LDL-C/HDL-C ratio (2.4), the patients were divided into two groups: low LDL-C/HDL-C group (LDL-C/HDL-C≤2.4, n=1 867) and high LDL-C/HDL-C group (LDL-C/HDL-C>2.4, n=1 994). Baseline data and 2-year major adverse cardiovascular and cerebrovascular events (MACCE) were collected and analyzed in order to find the differences between premature CHD patients at different LDL-C/HDL-C levels, and explore the correlation between LDL-C/HDL-C ratio with the severity of coronary artery disease and MACCE. Results: The average age of the low LDL-C/HDL-C ratio group was (48.5±6.5) years, 1 154 patients were males (61.8%); the average age of high LDL-C/HDL-C ratio group was (46.5±6.8) years, 1 523 were males (76.4%). The number of target lesions, the number of coronary artery lesions, the preoperative SNYTAX score and the proportion of three-vessel coronary artery disease in the high LDL-C/HDL-C group were significantly higher than those in the low LDL-C/HDL-C group (1.04±0.74 vs. 0.97±0.80, P=0.002; 2.04±0.84 vs. 1.85±0.84, P<0.001; 13.81±8.87 vs. 11.70±8.05, P<0.001; 36.2% vs. 27.4%, respectively, P<0.001). Correlation analysis showed that there was a significant positive correlation between LDL-C/HDL-C ratio and preoperative SYNTAX score, the number of coronary artery lesions, the number of target lesions and whether it was a three-vessel coronary artery disease (all P<0.05). The 2-year follow-up results showed that the incidence of MACCE was significantly higher in the high LDL-C/HDL-C group than that in the low LDL-C/HDL-C group (6.9% vs. 9.1%, P=0.011). There was no significant difference in the incidence of all-cause death, cardiac death, myocardial infarction, stroke, revascularization and bleeding between the two groups. Cox multivariate regression analysis showed that the LDL-C/HDL-C ratio has no correlation with 2-year MACCE, death, myocardial infarction, revascularization, stroke and bleeding events above BARC2 in patients with premature CHD. Conclusion: High LDL-C/HDL-C ratio is positively correlated with the severity of coronary artery disease in patients with premature CHD. The incidence of MACCE of patients with high LDL-C/HDL-C ratio is significantly higher during 2 years follow-up; LDL-C/HDL-C ratio may be an indicator for evaluating the severity of coronary artery disease and long-term prognosis in patients with premature CHD.

ABSTRACT

INTRODUCTION@#The coronavirus disease 2019 (COVID-19) pandemic has had an unprecedented impact in Asia and has placed significant burden on already stretched healthcare systems. We examined the impact of COVID-19 on the safety attitudes among healthcare workers (HCWs), as well as their associated demographic and occupational factors, and measures of burnout, depression and anxiety.@*METHODS@#A cross-sectional survey study utilising snowball sampling was performed involving doctors, nurses and allied health professions from 23 hospitals in Singapore, Malaysia, India and Indonesia between 29 May 2020 and 13 July 2020. This survey collated demographic data and workplace conditions and included three validated questionnaires: the Safety Attitudes Questionnaire (SAQ), Oldenburg Burnout Inventory and Hospital Anxiety and Depression Scale. We performed multivariate mixed-model regression to assess independent associations with the SAQ total percentage agree rate (PAR).@*RESULTS@#We obtained 3,163 responses. The SAQ total PARs were found to be 35.7%, 15.0%, 51.0% and 3.3% among the respondents from Singapore, Malaysia, India and Indonesia, respectively. Burnout scores were highest among respondents from Indonesia and lowest among respondents from India (70.9%-85.4% vs. 56.3%-63.6%, respectively). Multivariate analyses revealed that meeting burnout and depression thresholds and shifts lasting ≥12 h were significantly associated with lower SAQ total PAR.@*CONCLUSION@#Addressing the factors contributing to high burnout and depression and placing strict limits on work hours per shift may contribute significantly towards improving safety culture among HCWs and should remain priorities during the pandemic.

ABSTRACT

Licorice, one of the most commonly used medicinal materials in China, grows mainly in arid and semi-arid regions and has important economic and ecological values. Basic leucine zipper (bZIP) transcription factors in plants play an important role in regulating biological or abiotic stress responses, growth, and secondary metabolite synthesis. bZIP transcription factors in the published whole genome database of Glycyrrhiza uralensis were identified using bZIP sequences found in Arabidopsis thaliana genome as reference, and ABA-dependent bZIP genes were identified by using Illumina high-throughput sequencing. The physical and chemical properties, structure of the encoded proteins, and the gene expression patterns with exogenous ABA stress were analyzed. A total of 69 bZIP transcription factor genes were identified in G. uralensis, named Gubzip1-69, and they were divided into 10 subfamilies (A-I and S) according to their similarity to bZIPs of A. thaliana. By calculating the relative expression levels of the 69 GubZIPs genes under different concentrations of exogenous ABA stress, genes that may be involved in the regulation of ABA signaling pathways were identified, namely GubZIP1, GubZIP5, GubZIP8, GubZIP30, GubZIP33 and GubZIP56. The results of expression pattern analysis of these GubZIPs genes under exogenous ABA stress showed that the expression pattern of GubZIPs genes changed significantly with 50 mg·L-1 ABA. The relative expression levels of these genes decreased 3 h after treatment, and gradually increased 6 h after treatment. Except for GubZIP8, the relative expression levels of these genes were significantly increased after 12 h. Further research on the function of bZIP transcription factors of G. uralensis and elucidating their regulatory mechanisms should be of interest and will provide a scientific basis for cultivating high-quality cultivars of G. uralensis through molecular breeding methods.

ABSTRACT

Objective:To explore the therapeutic effect and mechanism of Chaihu Yueju decoction on model rats induced by chronic unpredictable mild stress (CUMS). Method:The 60 SD rats were randomly divided into normal group, model group, Chaihu Yueju decoction low, medium and high-dose groups(0.3, 0.6, 1.2 g·kg-1) and fluoxetine hydrochloride group(0.2 mg·kg-1), 10 for each group. The model rats was established by chronic unpredictable mild stress for 5 weeks, and then Chaihu Yueju decoction and fluoxetine hydrochloride were given to the corresponding treatment group by gavage for 3 weeks. In the last week of gavage, Morris water maze training and testing were conducted. After the last day of gavage, sugar water preference and other behavioral experiment were tested. The sugar water preference test was used to detect the degree of pleasure deficiency in rats before and after treatment, the open field test was used to detect the depression of rats before and after treatment, the spatial memory ability was tested by Morris water maze. Western blot was used to detect the levels of tumor necrosis factor-α(TNF-α), 5-hydroxytryptamine receptor 1A (5-HT1A), extracellular signal-regulated kinase (ERK) and synapse associated protein in hippocampus of each group, Gloji and Nissl staining was used to observe the changes of dendritic spines and Nissl bodies in the hippocampus CA3. Result:Compared with normal group, the weight, sugar water preference rate, the scores of horizontal and vertical movement were significantly reduced (P<0.05), and the immobility time was significantly prolonged in model group (P<0.05). Meanwhile, the ability of learning and memory in model group decreased (P<0.05). Western blot results showed that the levels of TNF-α was significantly increased (P<0.05), and the levels of 5-HT1A, p-ERK, cyclic adenosine phosphate reactive element binding protein (CREB), p-CREB, Synapsin-1,Synaptophysin, glutamate receptor subtype-1(GluR-1)and postsynaptic membrane protein-95(PSD-95) in model group were significantly decreased (P<0.05). Gloji and Nissl staining results showed that the density of dendritic spines and the number of Nissl body in the hippocampal CA3 of the model group was obviously attenuate (P<0.05). The results show that the neurons were evidently damaged. Compared with model group, the weight, sugar water preference rate, the scores of horizontal and vertical movement were clearly increased (P<0.05) and the immobility time was significantly shortened in fluoxetine hydrochloride group, middle dose and high dose Chaihu Yueju decoction group (P<0.05). Western blot results showed that the levels of synaptophysin, GluR-1 and PSD-95 were significantly increased in fluoxetine hydrochloride group, middle dose and high dose Chaihu Yueju decoction group. The level of TNF-α was significantly decreased (P<0.05), the levels of 5-HT1A, p-ERK, CREB, p-CREB and Synapsin-1 were remarkably increased (P<0.05), especially the high dose group of Chaihu Yueju decoction. Gloji and Nissl staining results showed that the density of dendritic spines and the number of Nissl body in the hippocampal CA3 of high dose group were similarly increased in a dose-dependent manner. Conclusion:Chaihu Yueju decoction could improves the weight, the depressive despair, autonomous activity ability and learning and memory ability of DP model rats. Its mechanism is closely related to attenuating the inflammatory reaction and enhancing the levels of 5-HT1A receptor protein, ERK and synapse related protein, then activating 5-HT/CREB and ERK/CREB signaling pathways, increasing the number and distribution of dendritic spines and repairing damaged neurons in the DP model rat's hippocampus.

ABSTRACT

Objective: As traditional techniques for microscopic identification of Chinese medicines currently lack objective and high-quality reference images, here we developed a systemic procedure to be used in microscopic identification of Chinese medicines, which would lead to more objective, effective and accurate identification process. Methods: Spatholobi Caulis (Jixueteng in Chinese) was used as the specimen in the development of such procedure. Jixueteng samples were microscopically examined in bright- and dark-field microscopy. Microscopic images were obtained by regular, EDF, and image stitching techniques. Results: The microscopic images of the characteristics in pulverized Jixueteng were captured, thanks to EDF imaging and image stitching techniques which allowed the detailed and full sighting of each characteristic to be obtained simultaneously. Different layers in anatomical transverse section, including cork, phelloderm, cortex, phloem, cambium, xylem and pith, were distinctively observed. Moreover, by comparing images of bright- and dark-field microscopy, birefringent and non- birefringent components could readily be distinguished. Conclusion: With application of the developed procedure, high-definition, panoramic and microscopic images were acquired, which could be used as the reference images for microscopic identification of Chinese medicines.

ABSTRACT

italic>Dendrobium moniliforme is an important source of Dendrobii Caulis and one of the main sources of authentic Fengdou. The complete chloroplast genome of D. moniliforme was sequenced using Illumina Hiseq technology and its gene map and genomic structure were analyzed. Then comparative and phylogenetic analysis of the complete chloroplast genomes of D. moniliforme and its related species were conducted. The chloroplast genome of D. moniliforme was 150 754 bp in length and had a typical quadripartite structure with a large single copy (LSC, 84 818 bp), a small single copy (SSC, 14 124 bp) and two inverted repeats (IRs, 25 906 bp each). A total of 123 chloroplast genes were annotated, including 77 protein-coding genes, 38 tRNA genes and 8 rRNA genes, of which 17 genes contained introns. Bioinformatics analysis identified 53 SSR sites, most of which had A-T base preference. A phylogenetic tree was constructed using the chloroplast genome sequences of 33 Dendrobium species. The results showed that Dendrobium complex species were clustered in a single large branch, indicating that they were closely related. This study provides a scientific basis for the identification of D. moniliforme and the phylogenetic relationship of D. moniliforme complex species necessary for Herbgenomics research.

ABSTRACT

As abscisic acid (ABA) receptor, the pyrabactin resistance 1-like (PYR/PYL) protein (named PYL for simplicity) plays an important part to unveil the signal transduction of ABA and its regulatory mechanisms. Glycyrrhiza uralensis, a drought-tolerant medicinal plant, is a good model for the mechanism analysis of ABA response and active compound biosynthesis. However, knowledge about PYL family in G. uralensis remains largely unknown. Here, 10 PYLs were identified in G. uralensis genome. Characterization analysis indicated that PYLs in G. uralensis (GuPYLs) are relatively conserved. Phylogenetic analysis showed that GuPYL1-3 belongs to subfamily I, GuPYL4-6 and GuPYL10 belong to subfamily II and GuPYL7-9 belongs to subfamily III. In addition, transcriptome data presented various expression levels of GuPYLs under different exogenous ABA stresses. The expression pattern of GuPYLs was verified by Quantitative real-time polymerase chain reaction (qRT-PCR). The study proved that GuPYL4, GuPYL5, GuPYL8 and GuPYL9 genes are significantly up-regulated by ABA stress and the response process is dynamic. This study paves the way for elucidating the regulation mechanism of ABA signal to secondary metabolites and improving the cultivation and quality of G. uralensis using agricultural strategies.

ABSTRACT

Pyrrosia petiolosa, Pyrrosia lingua and Pyrrosia sheareri are recorded as original plants of Pyrrosiae Folium (PF) and commonly used as Chinese herbal medicines. Due to the similar morphological features of PF and its adulterants, common DNA barcodes cannot accurately distinguish PF species. Knowledge of the chloroplast (cp) genome is widely used in species identification, molecular marker and phylogenetic analyses. Herein, we determined the complete cp genomes of three original species of PF via high-throughput sequencing technologies. The three cp genomes exhibited a typical quadripartite structure with sizes ranging from 158 165 to 163 026 bp. The cp genomes of P. petiolosa and P. lingua encoded 130 genes, whilst that of P. sheareri encoded 131 genes. The complete cp genomes were compared, and five highly divergent regions of petA-psbJ, matK-rps16, ndhC-trnM, psbM-petN and psaC-ndhE were screened as potential DNA barcodes for identification of Pyrrosia genus species. The phylogenetic tree we obtained indicated that P. petiolosa and P. lingua are clustered in a single clade and, thus, share a close relationship. This study provides invaluable information for further studies on the species identification, taxonomy and phylogeny of Pyrrosia genus species.

ABSTRACT

Ginsenoside Rh2 is a tetracyclic triterpenoid saponin monomer containing a dammarane-type skeleton, with advantages of low toxicity, low molecular weight, good fat solubility and strong anticancer effect, and is the main anticancer effective in ginseng. In recent years, there have been emerging findings on ginsenoside Rh2, indicating an obvious anticancer activity against a variety of cancers with a high morbidity and mortality. Particularly, ginsenoside Rh2 has a significant anti-hepatocarcinoma effect, so the studies on the mechanism of action have gradually been given attention. In this paper, we have reviewed more than 100 domestic and foreign relevant literatures in Chinese and English databases in the past 20 years, such as CNKI, Wanfang Data, VIP Data, Pub Med, and conducted detailed collection, analysis and summary for the contents of the anti-hepatocarcinoma mechanism of ginsenoside Rh2. According to the findings, although there are many reports on the anti-hepatocarcinoma effect of ginsenoside Rh2, the mechanism of action of ginsenoside Rh2 against liver cancer has not been systematically elaborated. Therefore, this paper comprehensively discusses the anti-hepatocarcinoma effect of ginsenoside Rh2, clarifies that the mechanism of action of ginsenoside Rh2 against liver cancer may be related with the inhibition of the proliferation of hepatoma cells, the induction of differentiation of hepatoma cells, the promotion of apoptosis of hepatoma cells, the inhibition of invasion and metastasis of hepatoma cells, the reduction of drug resistance of liver cancer cells, and the improvement of immunity. For the first time, the mechanism of action of ginsenoside Rh2 against liver cancer was comprehensively summarized, which provided reference for researches on ginsenoside Rh2 against liver cancer, evidence and ideas for further researches on ginsenoside Rh2, new research directions for the treatment of liver cancer and new hope to patients with liver cancer.

ABSTRACT

The definition of hypertension has been the object of controversy for many years. The First Report of the Joint National Committee( JNC-1) on Detection, Evaluation, and Treatment of High Blood Pressure was issued in 1977 and the levels of blood pressure above 160/95 mmHg was considered as high blood pressure(BP). The early JNC series guidelines are relatively vague on the diagnostic criteria and treatment goals of hypertension, and put more emphasis on diastolic blood pressure(DBP) in hypertension diagnosis. Since the publication of JNC VI reports, hypertension is defined as office systolic blood pressure(SBP) values≥140 mmHg and/or DBP values≥90 mmHg. The 2017 ACC/AHA Hypertension Guidelines changed the diagnostic criteria for hypertension by 130/80 mmHg and has caused widespread controversy at home and abroad. The Chinese Medical Doctor Association issued a scientific statement on the diagnostic criteria for hypertension and treatment targets of high BP in China. Although the standards proposed by the new ACC/AHA hypertension guideline is not recognized by other national guidelines, its concept of earlier prevention of hypertension has been widely accepted.

ABSTRACT

Genetic as well as genomic study has advanced the development of precision medicine. We are marching on the road for right patients who are receiving more and more right treatment at right time. In hypertension field, precision medicine is available, actionable and affordable. First and the most practical advancement is monogenic hypertension, the disease-genes have been found for at least 17 types of monogenic hypertension. These patients can be precisely treated according to their carried gene mutation. Secondly, pharmacogenetic and pharmacogenomic guided anti-hypertensive drug selection, very promising but lack of clinic outcome data to support widely clinical application. Majority of hypertension are due to multiple genetic and environmental factors. GWAS fund some genetic variants related to primary hypertension, but these variants can only be responsible for 1-10% of blood pressure variation. We have a long way to go in exploring the real cause of primary hypertension.

ABSTRACT

OBJECTIVE@#To study the protective effect of vitamin A on residual pancreatic β cell function in children with type 1 diabetes mellitus (T1DM) and its mechanism.@*METHODS@#A total of 46 children with T1DM (with a course of disease of 0.5-1 year) were randomly divided into an intervention group and a non-intervention group (n=23 each). The children in both groups were given insulin treatment, and those in the intervention group were also given vitamin A at a daily dose of 1 500-2 000 IU. A total of 25 healthy children were enrolled as the control group. The daily dose of insulin was calculated for the children with T1DM, and the serum levels of glycosylated hemoglobin (HbA1C), stimulated C-peptide, vitamin A, and interleukin-17 (IL-17) were measured before intervention and 3 months after intervention.@*RESULTS@#Before vitamin A intervention, the intervention group and the non-intervention group had a significantly lower serum level of vitamin A and a significantly higher level of IL-17 than the control group (P<0.01). After 3 months of intervention, the intervention group had significantly lower serum IL-17 level and insulin dose and a significantly higher level of stimulated C-peptide than the non-intervention group (P<0.05).@*CONCLUSIONS@#Vitamin A may protect residual pancreatic β cell function, possibly by improving the abnormal secretion of IL-17 in children with T1DM.

Objective To investigate the clinical features and prognosis of central nervous system(CNS)in-volvement in Epstein-Barr virus(EBV)associated hemophagocytic lymphohistiocytosis(HLH).Methods A total of 89 patients with EBV-HLH diagnosed in Children's Hospital of Chongqing Medical University from June 2006 to Octo-ber 2015 were divided into involved CNS group and non-involved group according to whether there was CNS involve-ment. The clinical manifestations,laboratory examinations and outcomes of these two groups were analyzed. Results Among these 89 patients with EBV-HLH,39 patients developed CNS disease,19 cases of them had neuro-logical symptoms or signs,including convulsions,unconsciousness,facial palsy,dysarthria,dysphagia,irritability,neck stiffness,Babinski sign positive,opisthotonus;9 cases of them had abnormal cerebrospinal fluid(CSF),with elevated white blood cell count and protein level;26 patients had abnormal brain images,including deepen or widening cortical sulci,atrophy,hemorrhage,high T2 signal in magnetic resonance imaging(MRI).The 3-year survival rate in involved CNS group was lower than those of non-involved group(66.7% vs.86.0%),and there was statistical significance (χ2=4.267,P=0.039).The involved CNS group had higher ferritin(χ2=5.092,3.921;P=0.024,0.048)and lower platelets(Z= -2.643,P=0.008)than those of non-involved group,and there were statistical significances.COX mul-tivariate analysis showed that neurological symptom and abnormal CSF were independent prognostic factors(RR=3.134, 3.339,all P<0.05).Conclusion CNS involvement is frequent in EBV-HLH.The prognosis of children with involved CNS group is worse than those of non-involved group.Neurological symptoms and abnormal CSF are related to poor prognosis.

ABSTRACT

BACKGROUND@#There is scanty evidence concerning the ability of Can Rapid Risk Stratification of Unstable Angina Patients Suppress Adverse Outcomes with Early Implementation of the ACC/AHA Guidelines (CRUSADE) and Acute Catheterization and Urgent Intervention Triage Strategy and Harmonizing Outcomes with Revascularization and Stents in Acute Myocardial Infarction (ACUITY-HORIZONS) scores to predict out-of-hospital bleeding risk after percutaneous coronary interventions (PCIs) with drug-eluting stents (DES) in patients receiving dual antiplatelet therapy. We aimed to assess and compare the long-term prognostic value of these scores regarding out-of-hospital bleeding risk in such patients.@*METHODS@#We performed a prospective observational study of 10,724 patients undergoing PCI between January and December 2013 in Fuwai Hospital, China. All patients were followed up for 2 years and evaluated through the Fuwai Hospital Follow-up Center. Major bleeding was defined as Types 2, 3, and 5 according to Bleeding Academic Research Consortium Definition criteria.@*RESULTS@#During a 2-year follow-up, 245 of 9782 patients (2.5%) had major bleeding (MB). CRUSADE (21.00 [12.00, 29.75] vs. 18.00 [11.00, 26.00], P 0.05). The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup.@*CONCLUSIONS@#CRUSADE and ACUITY-HORIZONS scores showed statistically significant but relatively limited long-term prognostic value for out-of-hospital MB after PCI with DES in a cohort of Chinese patients. The value of CRUSADE and ACUITY-HORIZONS scores did not differ significantly (P > 0.05) in the whole cohort, ACS subgroup, or non-ACS subgroup.
