Trends in the incidence of urothelial carcinoma in Taiwan after the ban on aristolochic acid-containing Chinese herbal preparations, 2001-2018: a national population-based cohort study.

PURPOSE: Urothelial carcinoma (UC) of the bladder (BUC) and the upper urinary tract (UTUC) are the two most common UCs. The incidence of UTUC in Taiwan is the highest worldwide. Aristolochic acid (AA) was identified as the main cause of UTUC in Taiwan. To explore trends in the incidence of UC in Taiwan after the ban on Chinese herbal preparations containing AA in 2003. METHODS: We used data from the Taiwanese National Health Insurance Research Database-linked Taiwanese National Cancer Registry for 2001-2018. UC was defined in accordance with the International Classification of Disease for Oncology. The age-standardized incidence was calculated on the basis of the World Health Organization standard population. Trends in the incidence were calculated as the annual percent change (APC) by using the Joinpoint regression program. RESULTS: Over the investigated period, the incidence of UC decreased at an average annual percent change (AAPC) of - 1.19% (95% CI - 1.47 ~ - 0.91, P < 0.001). However, the incidence in UTUC significantly increased, with the AAPC being 1.47% (95% CI 1.03 ~ 1.90, P < 0.001). In contrast, the incidence of BUC significantly decreased, with the overall AAPC being - 1.92% (95% CI - 2.3 ~ - 1.54, P < 0. 001). From 2001 to 2018, the overall incidence of UCs and BUC decreased in Taiwan, but the incidence of UTUC significantly increased. CONCLUSION: We suggest to apply the same review standards of new drug development process to herbal preparations and incorporate them into the adverse drug reaction or poison surveillance system. Most importantly, raise public awareness of the potential toxicity of phytotherapy.

Effects of fatty acid-ethanol amine (FA-EA) derivatives on lipid accumulation and inflammation.

This study aimed to investigate the effect of fatty acid-ethanol amine (FA-EA) derivatives (L1-L10) on the mitigation of intracellular lipid accumulation and downregulation of pro-inflammatory cytokines in vitro. First, the series of FA-EA derivatives were synthesized and characterized. Then, their cytotoxic, intracellular lipid accumulation and inhibition of pro-inflammatory cytokines were evaluated. The oil red O staining experiment showed that the tested compounds L4, L6, L8, L9, and L10 could reduce intracellular lipid accumulation induced by palmitic acid (PA). Moreover, ω-3/ω-6 PUFA-EA derivatives showed inhibitory effect on the production of pro-inflammatory cytokines in lipopolysaccharide (LPS) -stimulated RAW 264.7 cells. ω-3/ω-6 PUFA-EA derivatives at a concentrations of 10 µM could significantly decrease mRNA levels of IL-6, IL-1ß, and TNF-α, inhibit NO production, and alleviate the protein expression of IL-1ß in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. These data suggest that ω-3 PUFA-EA derivatives can be beneficial for further pharmaceutical development to treat chronic low-grade inflammation diseases such as obesity.

Knockdown of Long Noncoding RNA 01124 Inhibits the Malignant Behaviors of Colon Cancer Cells via miR-654-5p/HAX-1.

Background: Previous studies have shown that long noncoding RNAs (lncRNAs) play a key role in cancer, including colon cancer (CC). However, the exact role of long noncoding RNA 01124 (LINC01124) in CC and its mechanisms of action remain unknown. In this study, we investigated the functional effects and the possible mechanism of LINC01124 in CC. Methods: We first determined the expression of LINC01124 in CC tissues (The Cancer Genome Atlas (TCGA) database) and cell lines (quantitative real-time polymerase chain reaction (qRT-PCR)). Functional analysis via Cell Counting Kit-8 (CCK-8), colony formation, cell cycle, wound healing and Transwell assays were performed, and a mechanistic experiment was performed with the western blotting. The function of LINC01124 was also determined in vivo using nude BALB/c mice. Results: The results showed that LINC01124 was upregulated in CC tissues and cell lines. Functional studies showed that knockdown of LINC01124 significantly suppressed the proliferation, migration, and invasion of colon cancer cells in vitro and in vivo. Subsequent mechanistic experiments indicated that LINC01124 acted as a sponge to suppress microRNA 654-5p, which targeted HAX-1. Downregulation of LINC01124 decreased the expression of HAX-1, and overexpression of the miR-654-5p inhibitor attenuated the sh-LINC01124-induced inhibition of CC cell proliferation, migration, and invasion. Conclusion: Collectively, this study revealed that the knockdown of LINC01124 inhibited the malignant behaviors of CC via the miR-654-5p/HAX-1 axis, suggesting that LINC01124 might be a therapeutic target for CC treatment.

Connexin 43 mediated the angiogenesis of buyang huanwu decoction via vascular endothelial growth factor and angiopoietin-1 after ischemic stroke.

Buyang Huanwu decoction (BYHWD), a classical prescription for ischemic stroke, has been reported to promote angiogenesis after focal ischemia. However, the mechanisms of the contribution of BYHWD on angiogenesis are still unclear. Connexin 43 (Cx43) played important roles in the functions of neurogliovascular unit. Therefore, the aim of this study was to explore the potential role of Cx43 in angiogenesis of the ischemic brain after BYHWD treatment. Middle cerebral artery occlusion (MCAO) was used to establish the model of focal ischemia. BYHWD was administrated intragastrically twice a day after MCAO with or without Gap26 (a specific Cx43 inhibitor). Western blot, neurological deficits, immunofluorescent staining, and Evans blue dye were used to confirm the role of Cx43 in angiogenesis after BYHWD treatment. The expression levels of total Cx43 and phosphorylated Cx43 were upregulated by BYHWD and peaked at 7 days post MCAO. Inhibition of Cx43 with Gap26 significantly attenuated the protective role of BYHWD in neurological behavior. BYHWD treatment promoted angiogenesis demonstrated by increased microvascular density, upregulated vascular endothelial growth factor (VEGF), and angiopoietin-1 (Ang-1), while inhibition of Cx43 with Gap26 attenuated these effects of BYHWD. In addition, Gap26 inhibited the beneficial effect of BYHWD on blood-brain barrier (BBB) integrity. These results suggested that Cx43 mediated the angiogenesis of BYHWD via VEGF and Ang-1 after focal ischemic stroke.

Uptake, translocation, and metabolism of thiamethoxam in soil by leek plants.

Thiamethoxam (TMX) is commonly applied on leek plants by root irrigation. It might be taken up by leek plants and thus has lasting dietary risk. In this study, the uptake, translocation, and metabolism of TMX in leek plants were investigated. The results obtained from both the hydroponic and soil experiments indicated that TMX could be easily translocated upward and accumulated in leek shoots after being absorbed by roots. The total absorbed TMX amount (Mtotal) in leek plants from the tested soils varied greatly with its adsorption governed by soil characteristics. Interestingly, Mtotal was closely correlated with the concentration of TMX in in situ pore water, indicating that TMX in in situ pore water could be a useful approach to predict uptake of this chemical by leek plants from various soils. Profoundly, clothianidin (CLO) was detected with concentration of 0.07-1.54 mg/kg in roots and 0.27-4.12 mg/kg in shoots at 14 d, respectively, suggesting that TMX is easily converted into CLO in leek plants. The results showed that TMX used in soil is easily absorbed by leek and accumulated in edible parts accompanying with formation of CLO.

[Toxicology studies for compound preparations of traditional Chinese medicine in ancient classic prescriptions].

According to Provisions for Drug Registration and Categories and Requirements of Application Dossiers for Traditional Chinese Medicine(TCM), non-clinical safety research/toxicology research should be conducted for classical compound Chinese medicine prescriptions(Categories 3.1 and 3.2), and the data should be submitted at the application for the marketing authorization. Based on the requirements of toxicology research in Categories and Requirements of Application Dossiers for Traditional Chinese Medicine, this study further refined and clarified the requirements of toxicology research on classical compound Chinese medicine preparations(Categories 3.1 and 3.2).

Association Between Pre-diagnostic Dietary Supplements Intake and Ovarian Cancer Survival: Findings From a Prospective Cohort Study in Chinese Women.

Background: As a result of a limited number of studies and inconsistent findings, there remains uncertainty in whether pre-diagnostic dietary supplements intake affects survival after ovarian cancer (OC) diagnosis. Methods: The association between pre-diagnostic dietary supplements intake and all-cause OC mortality was examined in the OC follow-up study, which included a hospital-based cohort (n = 703) of Chinese women diagnosed with OC between 2015 and 2020. Pre-diagnostic dietary supplements information was collected using self-administered questionnaires. Deaths were ascertained up to March 31, 2021, via death registry linkage. Cox proportional hazards were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for the aforementioned association. Results: A total of 130 women died during the median follow-up of 37.2 months (interquartile: 24.7-50.2 months). We found no evidence that any pre-diagnostic dietary supplements intake compared with never is associated with OC survival (HR = 0.75, 95%CI: 0.47-1.18). Furthermore, our study suggested no association for ever supplements intakes of vitamin A (HR = 0.48, 95%CI: 0.07-3.46), vitamin C (HR = 0.64, 95%CI: 0.27-1.54), vitamin D (HR = 1.19, 95%CI: 0.28-5.03), vitamin E (HR = 0.47, 95%CI: 0.06-3.87), multivitamin (HR = 0.49, 95%CI: 0.14-1.67), calcium (HR = 0.96, 95%CI: 0.53-1.72), and fish oil/DHA (HR = 0.31, 95%CI: 0.04-2.37) with OC survival. Interestingly, we only found a detrimental effect of vitamin B supplementation intake (HR = 3.78, 95%CI: 1.33-0.69) on OC survival. Conclusions: We found no evidence that any pre-diagnostic dietary supplements intake is associated with OC survival. Considering lower exposure of dietary supplements before OC diagnosis in the present study, further studies are warranted to confirm these findings.

Emissions of nitrogen oxides and volatile organic compounds from liquefied petroleum gas-fueled taxis under idle and cruising modes.

Liquefied petroleum gas (LPG) as an alternative fuel is increasingly used in mainland China, few reports are however available about emissions from LPG-fueled vehicles. In this study, 26 LPG-fueled taxis in Guangzhou, south China were tested using a chassis dynamometer to obtain their emission factors of nitrogen oxides (NOx) and volatile organic compounds (VOCs) under idle and cruising (10-60 km h-1) modes. The emission factors of NOx on average increased with speed from 4.13 g kg-fuel-1 at idling to 71.1 g kg-fuel-1 at 60 km h-1 at a slope of 10.6 g kg-fuel-1 per 10 km h-1 increase in speed. Alkanes were the most abundant (71.9%) among the VOCs in the exhaust, followed by alkenes (25.2%), ethyne (2.7%), and aromatic species (0.2%). Emission factors of VOCs at idling averaged 8.24 g kg-fuel-1, higher than that of 6.23-7.36 g kg-fuel-1 when cruising at 10-60 km h-1, but their ozone formation potentials (OFPs) were lower at idling (15.8 g kg-fuel-1) than under cruising (19.1-23.8 g kg-fuel-1) largely due to higher emission of more reactive alkenes under cruising mode. Emissions of both NOx and VOCs increased significantly with mileages. Measured emission factors of NOx and reactive VOCs in this study suggested that replacing the gasoline-powered taxis with the LPG-fueled taxis with LPG-gasoline bi-fuel engines and no efficient after-treatment devices would not benefit in reducing the emissions of ozone precursors, and strengthening the emission control for LPG vehicles with dedicated LPG engines and after-treatment converters, as did in Hong Kong, could further benefit in reducing the emission of photochemically active species when using LPG as alternative fuels.

Discovery of BMS-986144, a Third-Generation, Pan-Genotype NS3/4A Protease Inhibitor for the Treatment of Hepatitis C Virus Infection.

The discovery of a pan-genotypic hepatitis C virus (HCV) NS3/4A protease inhibitor based on a P1-P3 macrocyclic tripeptide motif is described. The all-carbon tether linking the P1-P3 subsites of 21 is functionalized with alkyl substituents, which are shown to effectively modulate both potency and absorption, distribution, metabolism, and excretion (ADME) properties. The CF3Boc-group that caps the P3 amino moiety was discovered to be an essential contributor to metabolic stability, while positioning a methyl group at the C1 position of the P1' cyclopropyl ring enhanced plasma trough values following oral administration to rats. The C7-fluoro, C6-CD3O substitution pattern of the P2* isoquinoline heterocycle of 21 was essential to securing the targeted potency, pharmacokinetic (PK), and toxicological profiles. The C6-CD3O redirected metabolism away from a problematic pathway, thereby circumventing the time-dependent cytochrome P (CYP) 450 inhibition observed with the C6-CH3O prototype.

Currently, there is a lack of high-quality evidence to support the effectiveness and safety of SXT on patients with CI. This systematic review protocol aims at describing a meta-analysis to evaluate the efficacy of SXT for the treatment of CI. METHODS: We will search the databases of PubMed, MEDLINE, Embase, Cochrane Library Central Register of Controlled Trials, China national knowledge infrastructure database (CNKI), Wan fang database, Chongqing VIP information, and SinoMed from their inception to Jun 2020. Two reviewers will independently screen Randomized controlled trials of SXT for the treatment of CI. The meta-analysis will be conducted using RevMan V.5.3 software. RESULTS: The results of this study will be published in a peer-reviewed journal. CONCLUSION: The conclusion of our systematic review will provide evidence to judge whether SXT is an effective intervention for patients with CI. TRIAL REGISTRATION NUMBER: 10.17605/OSF.IO/3F6ZH.

ARTP mutation and adaptive laboratory evolution improve probiotic performance of Bacillus coagulans.

Bacillus coagulans is a thermophilic, facultative anaerobic, spore-forming Gram-positive bacterium, which is used as a probiotic in animal feed and human dietary supplements. In the present study, a bile-resistant thermophilic B. coagulans WT-03 strain was isolated and genetically identified. Atmospheric pressure room temperature plasma (ARTP)-induced mutation combined with adaptive laboratory evolution (ALE) was used to improve the probiotic performance of B. coagulans WT-03. After 15 s of ARTP mutation and 40 days of ALE culture, a mutant artp-aleBC15 was obtained and showed the improved tolerance to pH 2.5 and 0.3% bile salt with a survival rate of 22.4%. Further studies showed that the artp-aleBC15 mutant exhibited a relatively stable morphology, lower permeability, and higher hydrophobicity of cell membrane compared with the parent strain of B. coagulans. Additionally, artp-aleBC15 could maintain homeostasis with an intracellular pH of over 4.5 and had the altered contents of saturated fatty acids/unsaturated fatty acids in the cell membrane at pH 2.5. Our study proved that ARTP mutation combined with ALE is an efficient mutagenesis strategy to improve the probiotic performance of B. coagulans for potential industrial use.Key Points• A B. coagulans strain that can grow at 80 °C and 0.3% bile salt was screened.• ARTP combined with ALE effectively mutated B. coagulans WT-03.• B. coagulans artp-aleBC15 mutant showed an improved probiotic performance.• The mutant exhibited the lower permeability and altered fatty acid contents in the cell membrane.

Efficacy and Side Effects of Drugs Commonly Used for the Treatment of Lower Urinary Tract Symptoms Associated With Benign Prostatic Hyperplasia.

Benign prostatic hyperplasia (BPH) is the most common benign disease of the prostate gland and is caused by benign hyperplasia of the smooth muscle cells and stromal cells in this important gland. BPH is also the most common disease underlying lower urinary tract symptoms (LUTS). The incidence of BPH increases with age and affects more than half of all men 50 years or older. BPH mainly exerts effects on urinary function and can seriously reduce a patient's quality of life. At present, treatment for BPH aims primarily to improve the quality of life and reduce the risk of BPH-related complications. Pharmacological therapy is recommended for moderate-to-severe cases of LUTS that are suggestive of BPH. A range of drugs is currently available to treat this condition, including α1-adrenoceptor antagonists, 5α-reductase inhibitors (5-ARIs), phosphodiesterase type 5 inhibitors (PDE5Is), muscarinic receptor antagonists (MRAs), ß3-adrenoceptor agonists, and plant extracts. Of these, the most commonly used drugs in the clinic are α1-adrenoceptor antagonists, 5-ARIs, and combination therapy. However, these drugs exert their effects via various mechanisms and are associated with adverse reactions. The purpose of this review is to provide current comprehensive perspectives on the mechanisms of action, efficacy, and adverse reactions associated with the drugs most commonly used for the treatment of BPH.

A mechanistic and empirical review of antcins, a new class of phytosterols of formosan fungi origin.

Antcins are unique phytosterols isolated from A. cinnamomea and A. salmomea, which are the endemic fungus of Taiwan. A. cinnamomea has long been highly valued medicinal mushroom in Taiwan and traditionally used as a folk remedy for various human illness. Recent scientific explorations claimed that the pharmacological activities of A. cinnamomea and A. salmomonea are gone beyond their original usage. The therapeutic efficacy of these medicinal mushrooms was attributed to their high content of unique bioactive secondary metabolites, including terpenoids, benzenoids, ubiquinol derivatives, polysaccharides, lignans, nucleic acids, steroids, and maleic/succinic acid derivatives. Antcins is a group of steroids in Antrodia spp. with ergostane skeleton received much attention in Taiwan's academic circle due to their broad-spectrum of biological activities. At present, twelve antcins, i.e. antcin A, B, C, D, E, F, G, H, I, K, M, and N along with twelve derivatives/epimers (25R/S-antcin A, B, C, H, I and K) and seven analogs (methyl antcinate A, B, G, H, K, L and N) were identified. Several studies have demonstrated that antcins possessed anti-cancer, anti-inflammation, anti-oxidant, anti-diabetic, anti-aging, immunomodulation, hepatoprotection, and hypolipedimic activities. The main goal of this review is to define the chemistry, isolation, advances in production, and biological activities of antcins and their derivatives/analogs. Special attention has been given to a detail view of their biological activities in vitro and in vivo and their pharmacological potentials.

Exploring microbial community structure and biological function in manured soil during ten repeated treatments with chlortetracycline and ciprofloxacin.

The changes of enzyme activities, microbial community structure and function, and the diversity and resistance level of antibiotic-resistant bacteria (ARB) were studied in soil during ten repeated treatments with chlortetracycline (CTC) and/or ciprofloxacin (CIP) together with organic manure (OM) under laboratory conditions. The activities of neutral phosphatase (NPA) and catalase (CAT) displayed the suppression-recovery-stimulation trend in the OM&CTC treatment but the stimulation trend in the OM&CTC&CIP treatment. The NPA was stimulated but the CAT was little affected in the OM&CIP treatment. Soil microbial functional diversity displayed the suppression-recovery-stimulation trend in the OM&CTC and OM&CTC&CIP treatments and the stimulation-suppression trend in the OM&CIP treatment with the treatment frequency. Metagenomic analysis showed that the relative abundances of Actinobacteria and Firmicutes in the antibiotic treatment significantly increased by 0.5-235.6%, but that of Proteobacteria decreased by 0.2-27.3% compared to the control with the treatment frequency. Furthermore, the relative abundances of dominant bacterial genera including Streptomyces, Actinomadura, Mycobacterium, and Streptococcus in the antibiotic treatment significantly increased by 1.1-10433.3% compared to the control. Meanwhile, repeated antibiotic treatments induced a significant increase in the diversity and resistance level of ARB isolates, especially in the OM&CTC treatment. It is concluded that repeated treatments with CTC and/or CIP can alter enzyme activities, microbial community structure and function, and increase the diversity and resistance level of ARB isolates.

Effect of Shen-Fu Injection () on Hemodynamics in Early Volume Resuscitation Treated Septic Shock Patients.

OBJECTIVE: To investigate the hemodynamic effect of Shen-Fu Injection (, SFI) in early volume resuscitation treated septic shock patients by monitoring pulse indicator continuous cardiac output (PICCO). METHODS: All septic shock patients admitted in the Intensive Care Unit of the Affiliated Hospital of Shandong University of Traditional Chinese Medicine from January 1st, 2014 to December 31th, 2015, were reviewed, and totally 65 were enrolled in this study. They were assigned to SFI group (33 cases) and control group (32 cases). All 65 patients underwent conventional treatment mainly including volume resuscitation, antibiotics and vasoactive drugs therapy. The patients of the SFI group received additional 100 mL of SFI intravenously every 12 h. In all 65 patients, the PICCO arterial catheter and vein catheter were implanted within 1 h after the diagnosis of septic shock. In the course of early volume resuscitation, hemodynamic data of patients were recorded by PICCO monitor at 0, 12, and 24 h after the catheter implantation. RESULTS: The hemodynamic indices of the two groups showed no significant differences at the beginning of 0 h (P>0.05). At 12 and 24 h, the hemodynamic indices of SFI group were significantly improved in comparison with the control group (P<0.05), including cardiac index (CI), global end diastolic volume index (GEDI), mean arterial pressure (MAP) and heart rate (HR). In addition, there was no significant change of extra-vascular lung water index between the two groups (P>0.05). CONCLUSION: SFI significantly improved hemodynamic indices such as CI, GEDI, MAP and HR in early volume resuscitation treated septic shock patients.

iTRAQ-Based Proteomics Analysis of Plasma of Myasthenia Gravis Patients Treated with Jia Wei Bu Zhong Yi Qi Decoction.

Myasthenia gravis (MG) is an autoimmune disease. A proportion of MG patients did not get satisfactory results after treatment with pyridostigmine and prednisone. Jia Wei Bu Zhong Yi Qi (Jia Wei BZYQ) decoction, a water extract from multiple herbs, has been demonstrated to be effective in the treatment of multiple "Qi deficiency type" diseases including MG in China. In this text, we investigated protein alterations in the plasma from healthy volunteers (C), MG patients without any treatment (T1), MG patients with routine western medical treatment (T2), and MG patients with combined treatments of Jia Wei BZYQ decoction and routine western medicines (T3) and identified some potential proteins involved in the pathogenesis and treatment of MG. iTRAQ (isobaric tags for relative and absolute quantitation) and 2D-LC-MS/MS (two-dimensional liquid chromatography-tandem mass spectrometry technologies) were employed to screen differentially expressed proteins. The identification, quantification, functional annotation, and interaction of proteins were analyzed by matching software and databases. In our project, 618 proteins were identified, among which 447 proteins had quantitative data. The number of differentially expressed proteins was 110, 117, 143, 115, 86, and 158 in T1 vs. C, T2 vs. C, T2 vs. T1, T3 vs. C, T3 vs. T1, and T3 vs. T2 groups, respectively. Functional annotation results showed that many differentially expressed proteins were closely associated with immune responses. For instance, some key proteins such as C-reactive protein, apolipoprotein C-III, apolipoprotein A-II, alpha-actinin-1, and thrombospondin-1 have been found to be abnormally expressed in T3 group compared to T1 group or T2 group. Interaction network analyses also provided some potential biomarkers or targets for MG management.

Pollution and ecological risk assessment of nutrients associated with deposited sediments collected from roof and road surfaces.

Surface-deposited sediment in urban areas is an essential environmental medium for assessing nutrient contamination. The total nitrogen (TN) and total phosphorus (TP) pollution associated with surface-deposited sediments can be transported into urban water bodies by runoff and can cause eutrophication of those water bodies. By analyzing the samples collected on roof surfaces and road surfaces, this study provides a comparison of the differences in TN and TP pollution loading in sediments on these two different impervious surface materials. Also, an assessment of the ecological risk of nutrients in surface-deposited sediments with respect to grain size fraction was performed. The results indicate that the TN and TP pollution loading in both road-deposited sediments and roof-deposited sediments indicated an asymmetric "W" trend along with grain size fraction, and both road-deposited sediments and roof-deposited sediments had the highest TN and TP pollution contribution when the particle size is between 250 and 500 µm. TN in roof-deposited sediments has high ecological risk when the particle size is less than 250 µm. These findings help to provide guidance for the management of surface-deposited sediment pollution.

[Relationship between pre-clinical toxicity and efficacy of traditional Chinese medicine].

Based on the different category of syndromes between traditional Chinese medicine(TCM) and Western medicine, the relationship between the efficacy and non-clinical toxicity of the TCM was analyzed. If TCM preparations have the same pharmacological targets to treat disease with modern medicine or the Chinese herbal preparations treat the diseases with its toxicity, their toxicity often exhibits the amplification and extension of activity; on the other hand, if TCM preparations have overlapped pharmacological targets but not completely the same with modern medicine, or if they have totally different pharmacological targets, the toxicity of TCM could not be inferred by pharmacological activity. With the great progress in extraction and separation technique for active parts of TCM as well as the application of some novel technique and excipients, some toxicity may be from the reactions unrelated with the pharmacological activity. In conclusion, better design and quality control could be obtained by understanding the relationship between pharmacological and toxicological study for the investigation of new traditional medicine.
