ABSTRACT

BACKGROUND AND AIMS: The use of corticosteroids in chronic drug-induced liver injury (DILI) is an important issue. Our previous randomized controlled trial showed that patients with chronic DILI benefited from a 48-week steroid stepwise reduction (SSR) regimen. However, it remains unclear whether a shorter course of therapy can achieve similar efficacy. In this study, we aimed to assess whether a 36-week SSR can achieve efficacy similar to that of 48-week SSR. METHODS: A randomized open-label trial was performed. Eligible patients were randomly assigned to the 36- or 48-week (1:1) SSR group. Liver biopsies were performed at baseline and at the end of treatment. The primary outcome was the proportion of patients with relapse rate (RR). The secondary outcomes were improvement in liver histology and safety. RESULTS: Of the 90 participants enrolled, 84 (87.5%) completed the trial, and 62 patients (68.9%) were women. Hepatocellular damage was observed in 53.4% of the cohort. The RR was 7.1% in the 36-week SSR group but 4.8% in the 48-week SSR group, as determined by per-protocol set analysis (p = 1.000). Significant histological improvements in histological activity (93.1% vs. 92.9%, p = 1.000) and fibrosis (41.4% vs. 46.4%, p = .701) were observed in both the groups. Biochemical normalization time did not differ between the two groups. No severe adverse events were observed. CONCLUSIONS: Both the 36- and 48-week SSR regimens demonstrated similar biochemical response and histological improvements with good safety, supporting 36-week SSR as a preferable therapeutic choice (ClinicalTrials.gov, NCT03266146).

ABSTRACT

Volatile halocarbons (VHCs) are important trace greenhouse gases and ozone-destroying substances and play an important role in global climate change. As an important producer of VHCs, the release of VHCs by marine microalgae is affected by marine environmental factors. Microplastics are an important pollutant in the ocean; however, there are few studies on VHCs release from marine microalgae under the influence of microplastics. This study aimed to explore the effects of different concentrations of polyethylene (PE) microplastics on the growth, photosynthesis, oxidative stress, and release of VHCs by diatoms and dinoflagellates by measuring the density of algae, maximum photoquantum efficiency (Fv/Fm), reactive oxygen species (ROS), and concentration of VHCs. The results revealed that PE microplastics mainly inhibited the growth of Nitzschia closterium f. minutissima and promoted the growth of Prorocentrum donghaiense. The addition of 50 µm PE microplastics had a shielding effect on the growth of the two microalgae, resulting in the inhibition of Fv/Fm of two kinds of microalgae, and the inhibition effect of PE microplastics on P. donghaiense was more significant. Compared with that in the control group, PE microplastic stress stimulated the increase in ROS production in algal cells, which caused an oxidative stress response in these microalgae, thereby promoting the release of three types of volatile brominated halocarbons.

ABSTRACT

Spatial distributions of dissolved and particulate dimethylsulfoxide (DMSOd and DMSOp) were investigated off the northern Antarctic Peninsula during the austral summer of 2018, an ecologically and climatically important region of the world. In the upper waters, DMSOd was concentrated in the ice-melt zone because DMSO functions physiologically as an intracellular osmolyte and cryoprotectant. DMSOd concentrations had a weak positive correlation with temperature but a negative correlation with nutrients. This highlighted the importance of temperature-dependent biological activities and photolysis in DMSOd production and the important role of the intracellular antioxidation system in phytoplankton cells. The decrease of average DMSOp:Chl-a ratios in upper waters from west to east, along with decreasing temperatures and increasing diatoms proportions in the phytoplankton, illustrates how seawater DMSO production capacities depend on ambient temperatures and the composition of phytoplankton assemblages. DMSOp were accumulated in deep waters through bio-debris accumulation and microbial activity.

ABSTRACT

BACKGROUND: Mucosal-associated invariant T cells (MAITs) are markedly reduced in patients with alcohol-associated liver disease (ALD); however, the potential mechanism underlying MAITs' loss remains elusive. Hence, we aimed to explore what induced MAITs' loss and its clinical significance. METHODS: The characteristics of pyroptotic MAITs were evaluated in a cohort of patients with ALD, including 41 patients with alcohol-associated liver cirrhosis (ALC) and 21 patients with ALC complicated with severe alcoholic hepatitis (ALC + SAH). RESULTS: In patients with ALD, blood MAITs were significantly decreased, hyperactivated, and displayed enhanced cell death through pyroptosis. The frequencies of pyroptotic MAITs increased with disease severity in patients with ALC and patients with ALC + SAH. These frequencies were negatively associated with the frequencies of MAITs and positively correlated with the levels of MAITs' activation, plasma levels of intestinal fatty acid-binding protein (a marker of intestinal enterocyte damage), soluble CD14, lipopolysaccharide-binding protein, and peptidoglycan recognition proteins (surrogate markers of microbial translocation). Pyroptotic MAITs were also found in the liver of patients with ALD. Interestingly, MAITs underwent further activation and pyroptosis in vitro under stimulation by Escherichia coli or direct bilirubin. Notably, blocking IL-18 signaling reduced the activation and frequencies of pyroptotic MAITs. CONCLUSIONS: The loss of MAITs in patients with ALD is, at least in part, due to cell death from pyroptosis and is associated with the severity of ALD. Such increased pyroptosis may be affected by dysregulated inflammatory responses to intestinal microbial translocation or direct bilirubin.

ABSTRACT

Purpose: The value of lymphadenectomy during radical nephroureterectomy (RNU) remains unclear. This study aimed to determine the effects of the removed lymph node (RLN) counts, positive lymph node (pLN) counts, and pLN density (pLND) on survival outcomes in patients with node-positive upper urinary tract urothelial cancer (UTUC). Methods: A total of 306 patients with node-positive UTUC in the Surveillance, Epidemiology, and End Results database between 2004 and 2016 were identified. Multivariable Cox regression analyses were used to evaluate the effect of RLN counts, pLN counts, and pLND on survival outcomes. The maximally selected rank statistics were used to determine the most informative cutoff value for pLND on survival outcomes. Results: The RLN counts or pLN counts were not associated with survival outcomes, whereas higher pLND was associated with lower cancer-specific survival (CSS) and overall survival (OS) [hazard ratio (HR) 1.75, P = 0.014 and HR 1.62, P = 0.036, respectively]. The most informative cutoff value for pLND in relation to survival was 27%. Patients with pLND ≥27% had worse 5-year survival rates than those with pLND <27% (52.9% vs. 75.9% for CSS and 18.7% vs. 34.2% for OS, each P < 0.05). Furthermore, the multivariable Cox regression model with pLND could predict 5-year CSS (AUC 0.732 vs. 0.647) or OS (AUC 0.704 vs. 0.621) more accurately than the model without pLND. Conclusions: For patients with node-positive UTUC, more lymph nodes removed do not offer a better therapeutic effect. However, pLND provides additional prognostic value.

ABSTRACT

Objective: To explore the research hotspot and frontier direction of TCM nursing of insomnia and provide reference for the follow-up study of the optimal scheme of TCM nursing of insomnia. Background: Insomnia is a common sleep-wake disorder, affects 6-10% of adults and was associated with independent higher risks of cardiovascular disease and diabetes. TCM Nursing Techniques of insomnia has a long history and has shown a definite impact. However, it's still lack of analysis in the field of the most commonly used and effective techniques, as well as the co-morbidities associated with insomnia. Therefore, the database was searched and analyzed to find effective TCM Nursing Techniques for insomnia and related diseases related to insomnia. Method: Randomized controlled trials on the intervention of TCM Nursing Techniques in insomnia were retrieved from Web of Science Core Collection and imported into CiteSpace 5.6.R5 visualization software. The works of literature were co-cited by keywords authors and institutions for visual analysis, and the co-morbidities associated with insomnia of TCM Nursing Techniques in literature was extracted manually. The symptoms of co-morbidities associated with insomnia were imported into Cytoscape 3.9.0 software and clustered by CytoHubba. Result: As of October 20, 2021, the literature published in the last 20 years from Web of Science Core Collection was screened, and the publication period of the included literature was from 2004 to 2021. From 2016 to now, the total number of articles has been increasing. A total of 146 articles were included, and the highest production year was 2020. There is little cooperation between states, institutions, and authors. China (including Hong Kong and Taiwan) and Hong Kong Polytech University are leading countries and institutions in this area. MYUNGHAENG HUR is the most cited author, and J ALTERN COMPLEM MED is the most cited journal. According to cluster analysis and keyword frequency, auricular therapy, aromatherapy, and acupressure are the three most commonly used techniques. While the top five co-morbidities are fatigue, anxiety, depression, pain and hemodialysis. The three frontier topics and the main research directions are sleep quality, comorbid insomnia and clinical trial design. Conclusion: We found that acupressure, aromatherapy, and auricular acupoint therapy are the most commonly used nursing methods of TCM to intervene in insomnia. However, these studies have limitations such as small sample size, lack of objectivity in evaluating sleep quality, and high heterogeneity of intervention measures, which are not conducive to forming TCM clinical nursing guidelines. Therefore, it is necessary to adopt objectified sleep quality evaluation methods, select suitable acupoints according to TCM theories, and design multi-center large-sample clinical trials based on the safety principle of randomized blind control. This study provides an in-depth perspective for insomnia research on TCM Nursing Techniques and includes information for follow-up research on TCM Nursing Techniques of insomnia.

ABSTRACT

OBJECTIVE: To observe the clinical effect of Modified Shenqi Dihuang Decoction (MSDD) on bone metastasis of hormone-sensitive PCa after castration. METHODS: Seventy-six hormone-sensitive PCa patients with bone metastasis were randomly divided into a control and an MSDD group of an equal number, the former treated by maximal androgen blockade (MAB) and the latter with MSDD in addition to MAB, both for 6 months. Comparisons were made between the two groups of patients in their TCM symptom scores, quality of life (QOL) scores and the incidence rates of castration resistance, bone metastasis and adverse events. RESULTS: Totally, 64 of the patients were included in the statistical analysis. Compared with the controls, the MSDD group showed significantly lower rates of castration resistance (71.87% vs 28.12%, P < 0.05) and new bone and visceral metastases (40.63% vs 18.75%, P < 0.05) and level of serum alkaline phosphatase after treatment (ï¼»328.5 ± 170.6ï¼½ vs ï¼»318.5 ± 165.8ï¼½ U/L, P < 0.05), as well as lower scores in the TCM symptoms of frequent micturition (2.05 ± 0.51 vs 1.64 ± 0.66, P < 0.05), loss of appetite (1.95 ± 0.48 vs 1.41 ± 0.39, P < 0.05), fatigue (2.59 ± 0.68 vs 1.39 ± 0.58, P < 0.05), back pain (1.76 ± 0.41 vs 1.26 ± 0.38, P < 0.05), weight loss (1.88 ± 0.75 vs 1.26 ± 0.80, P < 0.05) and self-evaluation (1.89 ± 0.58 vs 1.54 ± 0.63, P < 0.05), but a higher score in the physical status (Karnofsky Performance Scale) (70.45 ± 12.16 vs 79.87 ± 11.23, P < 0.05). There were no statistically significant differences in the Numeric Rating Scale for Pain score and the incidence of adverse events between the two groups of patients. CONCLUSIONS: Modified Shenqi Dihuang Decoction can effectively improve the QOL and TCM symptom scores of the patients with hormone-sensitive PCa after androgen castration, enhance the efficacy of modern drugs in the treatment of hormone-sensitive PCa, decrease the incidence of metastasis, improve the patient's serum indicators, reduce the pain associated with bone metastasis, and improve the patient's quality of life.

ABSTRACT

Herbal medicine is widely used in Asia as well as the west. Hepatotoxicity is one of the most severe side effects of herbal medicine which is an increasing concern around the world. Reynoutria multiflora (Thunb.) Moldenke (Polygonum multiflorum Thunb., PM) is the most common herb that can cause herb-induced liver injury (HILI). The recent scientific and technological advancements in clinical and basic research are paving the way for a better understanding of the molecular aspects of PM-related HILI (PM-HILI). This review provides an updated overview of the clinical characteristics, predisposing factors, hepatotoxic components, and molecular mechanisms of PM-HILI. It can also aid in a better understanding of HILI and help in further research on the same.

ABSTRACT

The photodegradation of dissolved organic sulfur (DOS) is a potential source of aqueous sulfate and its chemical precursors in surface water. However, the photochemical fate of DOS and factors that control its fate still remain unclear. Herein, we employed a DOS model featuring a photosensitizer (humic acids, HA) to investigate the photochemical degradation pathways of DOS in various natural water sources, from which we observed the substantial photosensitized formation of sulfate, methanesulfonic acid (MSA), carbonyl sulfide (COS), and carbon disulfide (CS2). However, the photochemical production of sulfate and MSA tends to be more efficient than COS and CS2. The formation of sulfur-containing photodegradation products was also strongly affected by the identity of the organic sulfur precursor, the oxygen concentration, and the pH, while the salinity did not significantly influence the production ratios. Our results revealed that the photosensitization of DOS contributed significantly to the overall production of sulfate and MSA production, especially in acidic and oxygen-enriched environments, which was attributed to the photochemical production of reactive intermediates, such as excited CDOM (3CDOM*) and reactive oxygen species (ROS). Considering the coexistence of DOS and photosensitizers in aquatic environments, photochemistry may play an essential role in the fate of aquatic DOS.

ABSTRACT

Marine-derived reactive gases constitute a substantial fraction of volatile organic compounds and directly impact atmospheric chemistry and the global climate. Light alkene emissions from marginal seas are limited, and their contribution to atmospheric concentrations is likely underestimated. We surveyed oceanic emissions of ethylene, propylene, and isoprene, as well as their potential controlling factors in the marginal seas of China during the cruises in 2014-2015. Significant temporal-spatial variations in ethylene, propylene, and isoprene concentrations were observed, with the highest occurring in summer near the coastal regions. Isoprene concentrations were primarily controlled by phytoplankton biomass (i.e., Chl-a) in coastal regions, while the elevated concentrations of ethylene and propylene were attributed to photochemical reactions with the high levels of dissolved organic matter (DOM). Additionally, the vertical distributions of ethylene and propylene mirrored light penetration, with exponential decrease in concentrations with depth. However, there were high values of ethylene and propylene observed at deep chlorophyll maximum, suggesting the existence of non-photochemical production pathways, most likely biological origin. Emissions of ethylene, propylene, and isoprene from the marginal seas of China were estimated to be 0.022, 0.024, and 0.011 Tg C yr-1, respectively, indicating they are important contributors to global non-methane hydrocarbons. Due to the scarcity of alkene emission data for marginal seas, current global emissions have been underestimated to some extent. It is essential to incorporate the contributions from marginal seas to accurately estimate alkene budgets on global scales.

ABSTRACT

BACKGROUND: Infection is common in acute-on-chronic liver failure (ACLF), which may worsen the clinical condition and prognosis. However, the characteristics of infection and its influence on prognosis in hepatitis B virus related ACLF (HBV-ACLF) as defined by the European Association for the Study of the Liver (EASL) have not been clarified. We aimed to investigate the characteristics of infection and its influence on mortality in patients with HBV-ACLF defined by EASL in China. METHODS: We performed a retrospective cohort study in patients with HBV-ACLF defined by EASL in a single center from January 2015 to December 2017. These patients were divided into two groups with and without infection. The incidence, sites of infection, isolated strains, and risk factors associated with mortality were evaluated. RESULTS: A total of 289 patients were included, among them 185 (64.0%) were diagnosed with an infection. The most common type of infection was pneumonia (55.7%), followed by spontaneous bacterial peritonitis (47.6%) and others. The gram-negative bacteria were the most frequent (58.3%). Patients with one, two, and three or more infection sites had a gradually increasing incidence of sepsis (P < 0.01), septic shock (P < 0.001), and ACLF-3 (P < 0.05). Also, patients with infection isolated one, two, and three or more strains showed a growing incidence of sepsis (P < 0.01) and septic shock (P < 0.001). Patients with infection showed a significantly higher 28-day mortality than those without (P < 0.01), especially in patients with ACLF-3. Infection was identified as an independent risk factor for 28-day mortality in all HBV-ACLF patients. Pneumonia and sepsis were identified as independent predictors of 28-day mortality for patients with infection. CONCLUSIONS: Infection is associated with severe clinical course and high mortality in HBV-ACLF defined by EASL. The increased number of infection sites or isolated strains was associated with the occurrence of sepsis and septic shock. Pneumonia and sepsis were independent predictors for mortality in HBV-ACLF patients with infection.

ABSTRACT

INTRODUCTION: The fundamental theory of traditional Chinese medicine (TCM) implies that when different diseases have the same pathogen, the syndromes of these individual diseases will be the same. "Treating different diseases with the same method" is a TCM principle suggesting that when different diseases have similar pathological changes during different stages of their development, the same method of treatment can be applied. Our study aims to analyze the concept "treating different diseases with the same method" from a molecular perspective, in order to clarify its biological basis and to objectively standardize future TCM syndrome research. OBJECTIVE: The TCM syndromes Qi deficiency and blood stasis have similar pathogenesis in relation to coronary heart disease (CHD) and stroke. We aim to use big data technology and complex network theory to mine the genes specifically relevant to these TCM syndromes. This study aims to explore the correlation between the biological indicators of CHD and stroke from a scientific perspective. METHODS: Mining the relevant neuroendocrine-immune (NEI) genes by means of gene entity recognition, complex network construction, network integration, and decomposition to categorize relevant syndrome terms and establish a digital dictionary of gene specifically related to individual diseases. We analyzed the biological basis of "treating different diseases with the same method" from a molecular level using the TCMIP v2.0 platform in order to categorize the TCM syndromes most relevant to CHD and stroke. RESULTS: We found 46 genes were involved in the TCM syndromes of Qi deficiency and blood stasis of CHD and stroke. The same genes and their molecular mechanism also appeared to be in close relation to inflammatory response, apoptosis, and proliferation. CONCLUSION: By using information extraction and complex network technology, we discovered the biological indicators of the TCM syndromes Qi deficiency and blood stasis of CHD and stroke. In the era of big data, our results can provide a new method for the researchers of TCM syndrome differentiation, as well as an effective and specific methodology for standardization of TCM.

ABSTRACT

BACKGROUND: Vancomycin remains a mainstay of the treatment of Gram-positive bacterial infections. It is crucial to accurately determine vancomycin serum concentration for adequate dose adjustment. OBJECTIVES: To evaluate the precision and accuracy of commercial assay techniques for vancomycin concentration and to assess the comparability of vancomycin detection methods in Chinese laboratories. METHODS: Human serum samples spiked with known concentrations of vancomycin were provided to laboratories participating in the external quality assessment scheme (EQAS). Assay methods included chemiluminescence, enzyme immunoassay (EIA) and so on. The dispersion of the measurements was analysed and the robust coefficient of variation (rCV), relative percentage difference (RPD) and satisfactory rate for method groups were calculated. Moreover, performance of the Chinese laboratories was assessed. RESULTS: A total of 657 results from 75 laboratories were collected, including 84 samples from 10 Chinese laboratories. The median rCV, median RPD and satisfactory rates classified by methods ranged from 1.85% to 15.87%, -14.75% to 13.34% and 94.59% to 100.00%, respectively. Significant differences were seen in precision, between kinetic interaction of microparticles in solution (KIMS) and other methods, and in accuracy, between enzyme-multiplied immunoassay technique (EMIT), fluorescence polarization immunoassay (FPIA) and other techniques. Vancomycin detection in China mainly depended on the chemiluminescence and EMIT methods, which tended to result in lower measurements. CONCLUSIONS: Although almost all assays in this study achieved an acceptable performance for vancomycin serum concentration monitoring, obvious inconsistencies between methods were still observed. Chinese laboratories were more likely to underestimate vancomycin concentrations. Thus, recognizing inconsistencies between methods and regular participation in vancomycin EQAS are essential.

ABSTRACT

BACKGROUND: As a large, prospective, multicenter study-based prognostic score for hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF), the Chinese group on the study of severe hepatitis B-acute-on-chronic liver failure score (COSSH-ACLFs), has been approved by some foreign scholars; however, its predictive value needs to be verified. This study investigated the predictive value of COSSH-ACLFs for short-term prognosis in Chinese patients with HBV-ACLF. METHODS: This retrospective cohort study included 751 patients with HBV-ACLF admitted to the Fifth Medical Center of Chinese PLA General Hospital between January 2011 and December 2014. Spearman method was used to assess the correlation of COSSH-ACLFs with classical scores. Different COX multivariate regression models were used to confirm the relationship between COSSH-ACLFs and short-term prognosis in patients with HBV-ACLF, and stratified analysis was used to further verify the stability of this relationship. We compared the predictive powers of COSSH-ACLFs and other classical scores using area under the receiver operating characteristic curve (AUROC) and Z-test. RESULTS: A total of 975 patients with HBV-ACLF were screened, and 751 were analyzed (623 male and 128 female). COSSH-ACLFs was the highest in patients with end-stage ACLF, followed by those with middle- and early-stage ACLF (H = 211.8, P < 0.001). In the fully adjusted model, COX multivariate regression analysis revealed that COSSH-ACLFs (as a continuous variable) was independently and positively correlated with mortality risk in patients with HBV-ACLF at 28 days (hazard ratio [HR]: 1.37 [1.22, 1.53], P < 0.001) and 90 days (HR: 1.43 [1.29, 1.58], P < 0.001). The same trend could be observed in the crude model and minimally adjusted model. The AUROCs of COSSH-ACLFs for 28-day and 90-day prognoses in patients with HBV-ACLF were 0.807 and 0.792, respectively, indicating a stronger predictive accuracy than those of classic models. CONCLUSIONS: COSSH-ACLFs, with a superior predictive accuracy compared with other classical scores, can strongly predict short-term prognosis in Chinese patients with HBV-ACLF.

ABSTRACT

During an oceanographic campaign in the western Pacific Ocean from 12 August to 3 October 2014, the concentrations of five non-methane hydrocarbons (NMHCs) were measured in marine atmosphere and seawater. The average mixing ratios of ethane, ethylene, propane, propylene, and isoprene were 1.109 ±â€¯0.359, 0.658 ±â€¯0.137, 0.711 ±â€¯0.377, 0.429 ±â€¯0.139, and 0.255 ±â€¯0.201 ppbv, respectively. In general, atmospheric concentrations of ethane and propane showed significant decrease from the inshore area to the open ocean, while ethylene and propylene exhibited decreasing trends from low latitudes to high latitudes. The results suggested that atmospheric ethane and propane with long lifetimes were more likely influenced by the air mass transported from continent, while ethylene, propylene and isoprene with short lifetimes were mainly derived from the surface seawater. The average concentrations of ethane, ethylene, propane, propylene, and isoprene in the surface seawater were 6.6 ±â€¯5.8, 51.9 ±â€¯23.5, 15.4 ±â€¯4.3, 17.2 ±â€¯3.8, and 23.5 ±â€¯8.6 pmol L-1, respectively. A significant positive correlation was observed between ethane and propane (R2 = 0.45, n = 39, p < 0.001), implying that their production and removal pathways in the surface seawater were similar. High concentrations of isoprene were observed in the waters with high Chl-a values, suggesting that the biological process was a controlling factor. The estimated sea-to-air fluxes of ethane, propane, ethylene, propylene, and isoprene were in the range of 0.1-24.9, 4.2-235, 1.0-43.8, 1.5-90.2, and 2.1-149 nmol m-2 d-1, respectively. This study is of great importance to the contribution to the atmospheric NMHCs from the western Pacific Ocean and provides data supporting for global NMHCs emission estimates.

ABSTRACT

Canolol is a decarboxylated derivative of sinapic acid. Due to lipophilic nature, canolol is an excellent orally bioavailable phenol. It mainly occurs in roasted rapeseeds. It is documented in the literature as a potent antioxidant and safe for human health. The mode of antioxidant activity of canolol involves the suppression of various free radicals such as 02, ONOO and 'OOH. As evident from the literature, few studies have been carried out to explore the free radical scavenging activity of canolol. Thus, the objective of this review article is to summarize the available literature about free radical scavenging potential of this promising phenol to pave the path for further investigations about biological activities of canolol.

ABSTRACT

1-Deoxynojirimycin (DNJ, C6H13NO4, 163.17 g/mol), an alkaloid azasugar or iminosugar, is a biologically active natural compound that exists in mulberry leaves and Commelina communis (dayflower) as well as from several bacterial strains such as Bacillus and Streptomyces species. Deoxynojirimycin possesses antihyperglycemic, anti-obesity, and antiviral features. Therefore, the aim of this detailed review article is to summarize the existing knowledge on occurrence, extraction, purification, determination, chemistry, and bioactivities of DNJ, so that researchers may use it to explore future perspectives of research on DNJ. Moreover, possible molecular targets of DNJ will also be investigated using suitable in silico approach.

ABSTRACT

The aim of this study was to manage diabetes with medicinal plants (Gymnema sylvestre, Artemisia absinthium and Citillus colocynthis) in human patients with type II diabetes. Thirty two patients of type II diabetes from both sexes of 30-60 years age were registered for this study and distributed them into four groups, each having 8 patients. Capsules of each, Gymnema sylvestre, Artemisia absinthium and Citrullus colocynthis were given to patients twice a day for 30 days in 1 g per day dosage and investigated for glucose, triglyceride (TGL) and cholesterol level. Gymnema sylvestre reduced 37% glucose, 5% TGL, 13% cholesterol and 19% low desity lipoproteins (LDL) level in diabetic individuals. Citrullus colocynth reduced glucose, cholesterol and TGL and HDL-cholesterol level by 35, 6, 6, and 5%, respectively. Artemisia absinthium reduced 3% high desity lipoproteins (HDL) and 6% LDL level. From results, it can be concluded that the powdered Gymnema sylvestre, Citrulus colocynthis, and Artemisia absinthium possess good anti-diabetic features, however these herbal products had no significant effect on lipid profiles of the diabetic human.

ABSTRACT

The interfacial region plays a critical role in determining the electrical properties and energy storage density of dielectric polymer nanocomposites. However, we still know a little about the effects of electrical properties of the interfacial regions on the electrical properties and energy storage of dielectric polymer nanocomposites. In this work, three types of core-shell structured polymer@BaTiO3 nanoparticles with polymer shells having different electrical properties were used as fillers to prepare ferroelectric polymer nanocomposites. All the polymer@BaTiO3 nanoparticles were prepared by surface-initiated reversible-addition-fragmentation chain transfer (RAFT) polymerization, and the polymer shells were controlled to have the same thickness. The morphology, crystal structure, frequency-dependent dielectric properties, breakdown strength, leakage currents, energy storage capability, and energy storage efficiency of the polymer nanocomposites were investigated. On the other hand, the pure polymers having the same molecular structure as the shells of polymer@BaTiO3 nanoparticles were also prepared by RAFT polymerization, and their electrical properties were provided. Our results show that, to achieve nanocomposites with high discharged energy density, the core-shell nanoparticle filler should simultaneously have high dielectric constant and low electrical conductivity. On the other hand, the breakdown strength of the polymer@BaTiO3-based nanocomposites is highly affected by the electrical properties of the polymer shells. It is believed that the electrical conductivity of the polymer shells should be as low as possible to achieve nanocomposites with high breakdown strength.

ABSTRACT

The characteristics of holistic, dynamics, complexity, and spatial and temporal features enable "Omics" and theories of TCM to interlink with each other. HPO, namely, "characterization," can be understood as a sorting and generalization of the manifestations shown by people with diseases on the basis of the phenomics. Syndrome is the overall "manifestation" of human body pathological and physiological changes expressed by four diagnostic methods' information. The four diagnostic methods' data could be the most objective and direct manifestations of human body under morbid conditions. In this aspect, it is consistent with the connation of "characterization." Meanwhile, the four diagnostic methods' data also equip us with features of characterization in HPO. In our study, we compared 107 pieces of four diagnostic methods' information with the "characterization database" to further analyze data of four diagnostic methods' characterization in accordance with the common characteristics of four diagnostic methods' information and characterization and integrated 107 pieces of four diagnostic methods' data to relevant items in HPO and finished the expansion of characterization information in HPO.
