[Research progress on active ingredients of Coicis Semen].

As a common medicinal and edible resource in China, Coicis Semen has a long history of cultivation and medicinal use. Traditional Chinese medicine(TCM) clinically believes that Coicis Semen has the effect of strengthening the spleen and tonifying the lungs, clearing heat and dampness, removing pus and paralysis, and stopping diarrhea. Therefore, it is used to treat edema, foot odor, spleen deficiency, diarrhea, and other symptoms. The above effects are closely related to the active ingredients of Coicis Semen, such as esters, fatty acids, polysaccharides, proteins, as well as phenolic acids, sterols, flavonoids, lactams, triterpenes, alkaloids, and adenosine. Modern research has found that Coicis Semen also has anti-cancer, anti-inflammatory, antioxidant, hypoglycemic, and hypotensive effects and other pharmacological activities, and it can improve immunity and regulate lipid metabolism. Coicis Semen is widely distributed in China, mainly produced in Guizhou, Yunnan, Fujian, Sichuan, and other places, and the quality of Coicis Semen from different origins varies. From ancient times to the present, Coicis Semen processing methods have experienced the process from simple to complex, and the types of auxiliary materials are more extensive, such as soil, bran, and river sand. These processing methods have been inherited from generation to generation. Nowadays, the commonly used methods are bran-fried, stir-fried, sand-fried, etc. In this paper, by reviewing the relevant literature in China and abroad in recent years, the main active ingredients and related pharmacological effects of Coicis Semen are sorted out, and the effects of different origins and processing methods on the chemical composition of Coicis Semen are summarized, with a view to providing references for the comprehensive development and utilization of Coicis Semen and the further study of its mechanism of action.

[Research progress in gut-skin axis and its association with traditional Chinese medicine theory].

Currently, the gut-organ axis has become a hot research topic. As increasing attention has been paid to the role of gut microbiota in the health of organs, the complex and integrated dialogue mechanism between the gastrointestinal tract and the associated microbiota has been demonstrated in more and more studies. Skin as the largest organ in the human body serves as the primary barrier protecting the human body from damage. The proposal of the gut-skin axis has established a bidirectional link between the gut and the skin. The disturbance of gut microbiota can lead to the occurrence of skin diseases, the mechanism of which is complex and may involve multiple pathways in immunity, metabolism, and internal secretion. According to the theory of traditional Chinese medicine(TCM), the connection between the intestine and the skin can be established through the lung, and the interior disorders will definitely cause symptoms on the exterior. This paper reviews the research progress in the gut-skin axis and its correlation with TCM theory and provides ideas and a basis for cli-nical treatment and drug development of skin and intestinal diseases.

Association Between Nasal Colonization of Staphylococcus aureus and Eczema of Multiple Body Sites.

PURPOSE: Staphylococcus aureus is the critical pathogenic bacterium of eczema. The relationship between nasal colonization by S. aureus and eczema has not been well studied. We aimed to evaluate the associations between nasal colonization by S. aureus and eczema of multiple body sites, including persistent and ever-reported eczema. We further examined the associations between eczema and different subtypes of S. aureus, that is, methicillin-resistant S. aureus (MRSA) and methicillin-sensitive S. aureus (MSSA). METHODS: The real-world data from the US National Health and Nutrition Examination Survey were used. The associations were calculated using survey-weighted multinomial logistic regression models and further calculated in subgroups stratified by demographic factors. RESULTS: In total, 2,941 adults were included. The prevalence rate of S. aureus nasal carriage was significantly higher in adults with persistent hand eczema (51.0%) than in those with ever-reported hand eczema (23.3%) and never eczema (26.9%). S. aureus nasal colonization was associated with an approximately two-fold increased risk of persistent hand eczema (odds ratios ranges in different models: 2.86-3.06) without significant heterogeneity in the association by demographic factors. No significant associations between S. aureus nasal colonization and persistent eczema of other body sites or ever-reported eczema of multiple body sites (including hands) were observed. Furthermore, similar significant association between nasal colonization of MSSA and persistent hand eczema was seen; the association was much stronger (odds ratios ranges in different models: 4.64-6.54) for MRSA, although with borderline significant. CONCLUSIONS: Nasal colonization of S. aureus was associated with increased risk of persistent hand eczema. Our findings imply that preventive measures targeting S. aureus for the anterior nares should be considered in preventing and treating eczema.

The evidence framework of traditional Chinese medicine injection (Aidi injection) in controlling malignant pleural effusion: A clustered systematic review and meta-analysis.

INTRODUCTION: Aidi injection (Aidi), a traditional Chinese medicine injection, is often practiced to control malignant pleural effusion (MPE). OBJECTIVES: We performed a registered systematic review and meta-analysis (PROSPERO: CRD42022337611) to clarify the clinical role of Aidi in MPE, reveal optimal combinations of Aidi and chemical agents, their indications, therapeutic route and usage, and demonstrate their clinical effectiveness and safety. METHODOLOGY: All randomized controlled trials (RCTs) about Aidi in controlling MPE were collected from Chinese and English databases (up to October 2022). We clustered them into multiple homogenous regimens, evaluated the risk-of-bias at outcome level using a RoB 2, extracted and pooled the data using meta-analysis or descriptive analysis, and finally summarized their evidence quality. RESULTS: All 56 studies were clustered into intrapleural administration with Aidi alone or plus chemical agents, and intravenous administration with Aidi for MPE. Intrapleural administration with Aidi alone displayed similar clinical responses on Cisplatin (DDP) alone. Only administration with Aidi plus DDP significantly improved complete response and quality of life, and displayed a low pleurodesis failure, disease progression, hematotoxicity, gastrointestinal and hepatorenal toxicity. For patients with moderate to massive effusion, Karnofsky Performance Status score ≥ 50 or anticipated survival time ≥3 months, Aidi (50 ml to 80 ml each time, one time each week and three to eight times) plus DDP (20 to 30 mg, 40 to 50 mg, or 60 to 80 mg each time) significantly improved clinical responses. Most results had moderate to low quality. CONCLUSIONS: Current evidences indicate that Aidi, a pleurodesis agent, plays an interesting clinical role in controlling MPE. Aidi plus DDP perfusion is a most commonly used regimen, which shows a significant improvement in clinical responses. These findings also provide an indication and possible optimal usage for rational drug use.

Evaluation of two laboratory model methods for diarrheal irritable bowel syndrome.

BACKGROUND: Diarrheal irritable bowel syndrome (IBS-D) is a common chronic functional gastrointestinal disorder, and the underlying pathogenic mechanism is still unclear. Animal models that mimic the pathological state of IBS-D patients were constructed to provide a reference for later drug research and model development. METHODS: The IBS-D model was induced using restraint stress and chemical stimulation (rhubarb), and rats were divided into normal control group (NC), chemically stimulated group (CS), and restraint stress group (RS). Visceral motility responses to Colorectal Balloon Dilation (CRD) were measured by Abdominal Withdrawal Reflex (AWR); evaluation of faecal properties and water content; determination of colonic tissue tight junction (TJ) mRNA expression by RT-PCR; measurement of inflammatory cytokines by ELISA; and intestinal flora and short chain fatty acids. RESULTS: Compared to NC group, CS and RS group rats showed increased intestinal sensitivity and Bristol stool score, significant diarrheal symptoms and weight loss. Mucin 2, ZO-1, OCLN, CLDN4 mRNA expression was reduced and the intestinal mucosal barrier function was diminished. In addition, the levels of inflammatory factors IL-1ß, IL-6, IL-8, IL-10 and TNF-α increased, the abundance and diversity of intestinal flora decreased, the content of beneficial bacteria such as Bifidobacteria decreased, and SCFAs such as acetic acid, propionic acid and butyric acid decreased to different degrees. Although, no significant difference was observed for any molecular and inflammatory marker, but compared to CS group, RS group had less water in the stool, higher visceral sensitivity, and higher relative abundance of beneficial intestinal bacteria such as Actinobacteria. CONCLUSION: In conclusion, restraint stress combined with chemical stimulation can mimic the pathological state of diarrhoea symptoms, visceral hypersensitivity, reduced intestinal mucosal barrier permeability, immune regulatory dysfunction and dysbiosis in IBS-D patients. However, herbs with antibacterial effects such as rhubarb and senna, for example, are not suitable as the first choice for chemical stimulation, as they may lead to a decrease in harmful bacteria and an increase in beneficial bacteria in the intestinal fraction and do not perfectly mimic the imbalanced state of intestinal flora in IBS-D patients, while restraint stress may be a key factor in modelling.

Effect of Shenling Baizhu powder on immunity to diarrheal disease: A systematic review and meta-analysis.

Background: Diarrhea is one of the leading causes of death worldwide and is associated with immune dysfunction. The modulatory effects of Shenling Baizhu powder (SLBZS) on immune function in diarrheal disease have been validated in various animal models. However, the results of these studies have not been systematically evaluated. This study aimed to evaluate the preclinical data on SLBZS for the treatment of diarrhea from an immunological perspective. Methods: PubMed, Embase, Cochrane Library, CNKI, Wanfang Database, VIP, and Chinese Medicine Database were searched for all animal trials on SLBZS for the treatment of diarrhea published up to April 2022. Standardized mean differences (SMD) were used as effect sizes in the meta-analysis of continuous variables, including immune organs, immune cells, and immune cytokines. Subgroup analysis was performed according to animal species and disease models. The GRADE was used to assess the quality of evidence. Results: A total of 26 studies were included. Meta-analysis showed that compared to those in the model group, SLBZS significantly increased body weight [SMD = 1.54, 95% confidence interval (CI) (1.06, 2.02)], spleen mass [SMD = 1.42, 95% CI (0.98, 1.87)], thymus mass [SMD = 1.11, 95% CI (0.69, 1.53)], macrophage phagocytic capacity (SMD = 1.07, 95% CI [0.59, 1.54]), sIgA [SMD = 1.04, 95% CI (0.33, 1.74)], RBC-C3b-RR [SMD = 1.16, 95% CI (0.65, 1.67)], IL-2 [SMD = 1.52, 95% CI (0.89, 2.14)] and decreased diarrhea scores [SMD = -1.40, 95% CI (-2.03, -0.87)], RBC-IC-RR [SMD = -1.40, 95% CI (-1.94, -0.87)], and IL-8 [SMD = -2.80, 95% CI (-3.54, -2.07)]. Subgroup analysis showed that SLBZS regulated TNF-α, IL-1ß, and IL-10 in rats and mice, and improved IL-6 and IL-10 in different diseases, with differences between subgroups (p < 0.05). Owing to heterogeneity, the reliability of the results remains to be verified. The quality of evidence was "very low". Conclusion: SLBZS improve diarrhea symptoms by enhancing immune function. It has curative effects with differences between different species and diseases, however, because the reporting in the original studies was too unclear to be assessed, the analysis was inconclusive. For higher quality evidences, future research should pay attention to the scientific rigor of the experimental design and the completeness of the reported results.

Association of cannabis use disorder with cardiovascular diseases: A two-sample Mendelian randomization study.

Background: The use of cannabis has increased globally due to more regions decriminalizing marijuana use for therapeutic and recreational aims. Several observational studies have revealed that cannabis use is associated with an increased risk of adverse cardiovascular pathologies and diseases. Nevertheless, the causal associations between cannabis use and cardiovascular diseases remain unclear. Hence, we performed single-variable and multivariable Mendelian randomization (MR) to evaluate the association between cannabis use disorder and various cardiovascular diseases. Materials and methods: Summary statistics were collected from the largest-to-date genome-wide association studies (GWAS) of cannabis use disorder. The 12 SNPs for cannabis use disorder were used as instrumental variables in this study. MR estimates were pooled using a random-effects inverse-variance weighted (IVW) method. Simple median and weighted median methods were conducted as sensitivity analyses. Results: The genetic liability to cannabis use disorder was associated with an augmented risk of coronary artery disease, myocardial infarction, atrial fibrillation, heart failure, deep venous thrombosis, pulmonary embolism, and stroke. Except for stroke, the results were inconsistent in the sensitivity analyses. The overall patterns for the associations of cannabis use disorder with atrial fibrillation, heart failure, pulmonary embolism and stroke remained in multivariable MR analyses adjusting for potential mediators, including smoking, alcohol, body mass index, blood lipid, type 2 diabetes, hypertension, and depression. However, the association with coronary artery disease, myocardial infarction, and deep venous thrombosis did not persist in multivariable MR analyses. Mediation analysis demonstrated that smoking, body mass index, low-density lipoprotein, hypertension, and depression have more significant mediation effects, which suggests that these factors partly mediate the link from cannabis use disorder to coronary artery disease, myocardial infarction, and deep venous thrombosis. Conclusion: The genetic liability to cannabis use disorder was associated with a higher risk of atrial fibrillation, heart failure, pulmonary embolism, and stroke. The evidence for the association between cannabis use disorder, coronary artery disease, myocardial infarction, and deep venous thrombosis was weak. Hence, future use of cannabis for therapeutic and recreational aims should consider its potential impact on cardiovascular diseases.

Azole-Induced Color Vision Deficiency Associated with Thyroid Hormone Signaling: An Integrated In Vivo, In Vitro, and In Silico Study.

Azoles that are used in pesticides, pharmaceuticals, and personal care products can have toxic effects on fish. However, there is no information regarding azole-induced visual disorder associated with thyroid disruption. We evaluated changes in retinal morphology, optokinetic response, transcript abundance of the genes involved in color perception and hypothalamic-pituitary-thyroid (HPT) axis, and thyroid hormone (TH) levels in zebrafish larvae exposed to common azoles, such as climbazole (CBZ, 0.1 and 10 µg/L) and triadimefon (TDF, 50 and 500 µg/L), at environmentally relevant and predicted worst-case environmental concentrations. Subsequently, the effect of azoles on TH-dependent GH3 cell proliferation and thyroid receptor (TR)-regulated transcriptional activity, as well as the in silico binding affinity between azoles and TR isoforms, was investigated. Azole exposure decreased cell densities of the ganglion cell layer, inner nuclear layer, and photoreceptor layer. Zebrafish larvae exposed to environmentally relevant concentrations of CBZ and TDF showed a decrease in optokinetic response to green-white and red-white stripes but not blue-white stripes, consistent with disturbance in the corresponding opsin gene expression. Azole exposure also reduced triiodothyronine levels and concomitantly increased HPT-related gene expression. Molecular docking analysis combined with in vitro TR-mediated transactivation and dual-luciferase reporter assays demonstrated that CBZ and TDF exhibited TR antagonism. These results are comparable to those obtained from a known TR antagonist, namely, TR antagonist 1, as a positive control. Therefore, damage to specific color perception by azoles appears to result from lowered TH signaling, indicating the potential threat of environmental TH disruptors to the visual function of fish.

"Acupuncture" "data mining" "systematic review" "oxidative stress" "activation" may be the potential topics in the follow-up research development.Future development should focus on the scientific interpretation and analysis of the theory and practice of TCM by modern scientific and technological methods.The research on informatization, digitization, and knowledge of TCM theory and practice is pivotal to promoting the internationalization and modernization of TCM, which can help researchers explore new directions for future research and identify new perspectives for potential collaboration in the field.

Intrapleural Perfusion With Staphylococcal Enterotoxin C for Malignant Pleural Effusion: A Clustered Systematic Review and Meta-Analysis.

Introduction: The staphylococcal enterotoxin C (SEC), a commercially available bio-product from Staphylococcus aureus (S. aureus), has been widely used to control MPE. Objectives: We designed and performed a new systematic review (SR) and meta-analysis to clarify the perfusion protocols with SEC, determine their clinical effectiveness and safety, and reveal the indication and optimum usage for achieving the desired responses. Methodology: All randomized controlled trials (RCTs) about SEC for MPE were collected from electronic databases (from inception until July 2021), and clustered into multiple logical topics. After evaluating their methodological quality, we pooled the data from each topic using the meta-analysis or descriptive analysis, and summarized the evidence quality using the grading of recommendation assessment, development, and evaluation (GRADE) approach. Results: All 114 studies were clustered into SEC perfusion alone or plus chemical agents. The SEC alone showed a better complete response (CR), a lower pleurodesis failure, and adverse drug reactions (ADRs), and a higher fever than cisplatin (DDP) alone. The SEC and chemical agents developed 10 perfusion protocols. Among them, only SEC and DDP perfusion showed a better CR, a lower failure, disease progression and ADRs, and a higher fever than DDP alone. The SEC (100-200 ng per time, one time a week for one to four times) with DDP (30-40 mg, or 50-60 mg each time) significantly improved clinical responses for patients with moderate to large volume, Karnofsky performance status (KPS) scores ≥40, ≥50, or ≥60, and anticipated survival time (AST) ≥2 or 3 months. Most results were moderate to low quality. Conclusion: Current pieces of evidence indicate that super-antigen SEC is a pleurodesis agent, which provides an attractive alternative to existing palliative modalities for patients with MPE. Among 10 protocols, the SEC and DDP perfusion is a most commonly used, which shows a significant improvement in clinical responses with low ADRs. These findings also provide a possible indication and optimal usage for SEC and DDP perfusion.

The intrapleural administration with thymic peptides in malignant pleural effusion: A clusteredsystematicreview and meta-analysis.

BACKGROUND: Thymic peptides (TPs) are often used to control malignant pleural effusion (MPE). So, we performed a clustered systematic review and meta-analysis to clarify the treatment regimens of TPs for MPE, demonstrate their clinical effectiveness and safety, and reveal the indications and optimal usage for a desired effectiveness. MATERIALS AND METHODS: We collected all trials of TPs for MPE from Chinese and English databases (from inception until May 2021). After evaluating their bias risk, we pooled the data from each regimen using the meta-analysis or descriptive analysis, and summarized the evidence quality using the Grading of Recommendation Assessment, Development and Evaluation approach (GRADE). RESULTS: Thirty-four trials were clustered into TPs for MPE from lung cancer or miscellaneous tumors. The TPs combined with chemical agents were mainly used in MPE from lung cancer. All five regimens, only thymosin with oxaliplatin (L-OHP) significantly improved the complete response (CR) [2.40 (1.84 to 3.13)], quality of life [2.04 (1.20 to 3.48)], 0.5- and 1-year overall survival (OS) rate [5.75 (3.02 to 10.92) and 5.29, (1.71 to 16.36)]. It also up-regulated the T lymphocyte levels, and reduced the pleurodesis failure, disease progression and adverse events. In patients with moderate to large volume, Karnofsky Performance Status score ≥ 50 or anticipated survival time ≥ 3 months, the thymosin (300 mg/time, one time/week and lasting two to eight times) with oxaliplatin (100 mg/m2) achieved a desired response. Most results were moderate quality. CONCLUSIONS: The current evidences indicate that the TPs are important pleurodesis agents, which combination with chemical agents are mainly used in MPE from lung cancer. The thymosin with L-OHP is a main regimen, which shows a significant improvement in clinical responses, antitumor immunity, and with a reasonable security. The evidence also provides indications and optimal usage for achieving a desired effectiveness.

Chronic Exposure to Climbazole Induces Oxidative Stress and Sex Hormone Imbalance in the Testes of Male Zebrafish.

As the main active ingredient for the treatment of fungal infections, climbazole (CBZ) is commonly used in a variety of personal care products. After its use, CBZ enters the receiving environment directly or indirectly through domestic sewage. Its concentration can be up to several nanograms per liter in surface water. So far, the effects of CBZ on the reproductive system of female zebrafish have been systematically studied, but the potential toxicity mechanism of CBZ on male zebrafish still needs to be further explored. In this study, adult male zebrafish were exposed to CBZ at concentrations of 0.1, 10, and 1000 µg·L-1 for 28 days, and their testes were collected for histological, mass-spectrometry-based metabolomics, and biochemical analyses. We found that CBZ caused a significantly abnormal metabolism of purine and glutathione and triggered oxidative stress in zebrafish testes, thereby inducing testicular cell apoptosis. In addition, CBZ could inhibit the synthesis of essential sex hormones in the testis and thus reduce the sperm production. The conclusions of this study fill the data gap on the reproductive toxicity of CBZ to male zebrafish and highlight the ecotoxicological application of untargeted metabolomics in the biomarker discovery.

Toxic effects of triclocarban on larval zebrafish: A focus on visual dysfunction.

Triclocarban (TCC) is considered an endocrine disruptor and shows antagonist activity on thyroid receptors. In view of the report that thyroid hormone signaling mediates retinal cone photoreceptor specification, we hypothesize that TCC could impair visual function, which is vital to wildlife. In order to verify our hypothesis, we assessed alteration in the retinal structure (retinal layer thickness and cell density), visually-mediated behavior, cone and rod opsin gene expression, and photoreceptor immunostaining in zebrafish larvae exposed to TCC at environmentally realistic concentrations (0.16 ± 0.005 µg/L, L-group) and one-fifth of the median lethal concentrations (25.4 ± 1.02 µg/L, H-group). Significant decrease in eye size, ganglion cell density, optokinetic response, and phototactic response can be observed in the L-group, while the thickness of outer nuclear layer, where the cell bodies of cone and rod cells are located, was significantly reduced with the down-regulation of critical opsin gene (opn1sw2, opn1mw1, opn1mw3, opn1lw1, opn1lw2, and rho) expression and rhodopsin immunofluorescence in the H-group. It should be noted that TCC could affect the sensitivity of zebrafish larvae to red and green light according to the results of behavioral and opsin gene expression analysis. These findings provide the first evidence to support our hypothesis that the visual system, a novel toxicological target, is affected by TCC. Consequently, we urgently call for a more in-depth exploration of TCC-induced ocular toxicity to aquatic organisms and even to humans.

Intrapleural Administration With Rh-Endostatin and Chemical Irritants in the Control of Malignant Pleural Effusion: A Systematic Review and Meta-Analysis.

INTRODUCTION: A modified and recombinant human endostatin (Rh-endostatin) is often used in the control of malignant pleural effusion (MPE) through intrapleural infusion. OBJECTIVES: To demonstrate the clinical response, survival, and safety of Rh-endostatin plus chemical irritants, their optimal combinations, treatment threshold, and optimal usage, we performed a new systematic review and meta-analysis. METHODOLOGY: All randomized controlled trials (RCTs) were collected from Chinese and English electronic databases (from inception until August 2020). We pooled the data using a series of meta-analyses and summarized the evidence quality following the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach. RESULTS: We included 75 RCTs recruiting 4,678 patients, which reported six combinations for Rh-endostatin plus chemical irritants. Among the six combinations, only Rh-endostatin plus cisplatin (DDP) with enough trials might improve the complete response [2.29 (1.93, 2.71)] and quality of life [3.01 (2.49, 3.63)] and reduce treatment failure [0.29 (0.25, 0.33)] and progressive disease [0.27 (0.22, 0.34)]. It might not increase the risk of adverse drug reactions. For patients with lung cancer, moderate to massive effusion, initial treatment, Karnofsky Performance Status (KPS) score ≥60, or anticipated survival time ≥3 months, Rh-endostatin (30-45 mg each time, once or twice a week 3-4 times) plus DDP (30-60 mg/m2) obtained a significant improvement in clinical response and a reduction of failure and progressive disease. Most results had good robustness and moderate quality. CONCLUSIONS: Current evidence suggests that Rh-endostatin with DDP may be an optimal combination, which may improve clinical response and reduce failure and progressive disease with good safety. Rh-endostatin (30-40 mg each time, once or twice a week 3-4 times) with DDP (30-40 mg/m2) may be an optimal usage for achieving an ideal response.

Tenofovir disoproxil fumarate in Chinese chronic hepatitis B patients: Results of a multicenter, double-blind, double-dummy, clinical trial at 96 weeks.

BACKGROUND: Tenofovir disoproxil fumarate (TDF) is a prodrug of a nucleotide analogue. As an antiviral drug, TDF has been proposed in the first-line treatment of chronic hepatitis B (CHB). Qingzhong, a brand name of TDF, commercialized by Jiangsu Chia-tai Tianqing Pharmaceutical Co Ltd., and Viread, another brand name of TDF, commercialized by GlaxoSmithKline, have both been approved by the State Food and Drug Administration, China. AIM: To investigate the efficacy and safety of the two TDF agents in the treatment of Chinese CHB patients. METHODS: This trial was registered at ClinicalTrials.gov with the identifier number of NCT02287857. A total of 330 Chinese CHB patients, among which 232 were hepatitis B e antigen (HBeAg)-positive, were included in this 5-year-long, multicenter, double-blinded, double-dummy, randomized-controlled, non-inferiority phase III trial. The participants were initially randomized into two groups: Group A (n = 161), in which the participants received 300 mg Qingzhong once a day for 48 wk; and Group B, in which the participants received 300 mg Viread once a day for 48 wk. Starting from week 49, all the participants in Groups A and B received 300 mg Qingzhong once a day until the 96th week. In this study, the primary endpoint was the decrease in plasma level of hepatitis B virus (HBV) DNA at the 96th week, while the secondary endpoints were suppression of HBV replication, alanine aminotransferase (ALT) normalization, HBeAg loss, and HBeAg seroconversion rates. RESULTS: For the participants with HBeAg-positive CHB, the decrease in mean HBV DNA level relative to the baseline value was comparable between Groups A and B (5.77 vs 5.73 log10 IU/mL, P > 0.05) at the 96th week. In addition, similar percentages of HBeAg-positive participants in the two groups exhibited undetectable levels of HBV DNA, HBeAg loss, and HBeAg seroconversion (71.05% vs 77.97%, 31.00% vs 27.27%, and 20.22% vs 15.79%, respectively, in Group A vs Group B; P > 0.05). For the participants with HBeAg-negative CHB, the decrease in mean HBV DNA level relative to the baseline value was also comparable between Groups A and B (4.46 vs 4.70 log10 IU/mL, P > 0.05) at the 96th week. In addition, similar percentages of HBeAg-negative participants in the two groups exhibited undetectable levels of HBV DNA (87.23% vs 94.12% in Group A vs Group B, respectively; P > 0.05). Finally, similar percentages of CHB patients (HBeAg-positive or HBeAg-negative) in the two groups exhibited normalization of ALT (80.14% vs 84.57% in Group A vs Group B, respectively; P > 0.05), and similar incidences of adverse events were observed (106 vs 104 in Group A vs Group B, respectively; P > 0.05). CONCLUSION: Both Qingzhong and Viread are effective and safe in the treatment of Chinese CHB patients according to the results of our clinical trial.

The Optimal Adjuvant Strategy of Aidi Injection With Gemcitabine and Cisplatin in Advanced Non-small Cell Lung Cancer: A Meta-analysis of 70 Randomized Controlled Trials.

Introduction: Aidi injection (Aidi) is composed of cantharidin, astragaloside, ginsenoside, and elentheroside E. As an important adjuvant therapy, Aidi in combination with gemcitabine and cisplatin (GP) is often used in the treatment of non-small cell lung cancer (NSCLC). Objectives: We performed a new evaluation to demonstrate the clinical efficacy and safety of the Aidi and GP combination and further explored an optimal strategy for achieving an ideal response and safety level in advanced NSCLC. Methodology: We collected all the related trials from Chinese and English-language databases, analyzed their methodological bias risk using the Cochrane evaluation Handbook for Systematic Reviews of Interventions Version 5.1.0, extracted all the data using a predefined data extraction form, pooled the data using a series of meta-analyses, and finally summarized the quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach. Results: We included 70 trials with 5,509 patients. Compared with GP alone, the Aidi and GP combination showed a significant improvement in the objective response rate (ORR) [1.82 (1.62-2.04)], disease control rate (DCR) [2.29 (1.97-2.67)], and quality of life (QOL) [3.03 (2.55-3.60)] and a low incidence of hematotoxicity and gastrointestinal and hepatorenal toxicity. Aidi might be more suitable for patients who are first-treated, elderly, or patients with a Karnofsky Performance Status (KPS) score ≥ 60 or anticipated survival time (AST) ≥3 months. An Aidi (50 ml/day, 7-14 days/cycle for one to two cycles), gemcitabine (1000 mg/m2), and cisplatin (20-30 mg/m2, 40-50 mg/m2, or 60-80 mg/m2) might be an optimal regimen for realizing an ideal response and safety level. Most results were robust and of moderate quality. Conclusion: Current evidence indicates that Aidi's value in adjuvant chemotherapy may be broad-spectrum, not just for some regimens. The Aidi and GP combination may show a good short-term response, antitumor immunity, and safety level in patients with NSCLC. Aidi (50 ml/day, 7-14 days/cycle for one and two cycles) with GEM (1000 mg/m2) and DDP (20-30 mg/m2 or 40-50 mg/m2) may be an optimal regimen for realizing an ideal goal in patients who are first-treatment, elderly, or have a KPS score ≥ 60 or AST≥3 months.

Comparison of the Efficacy of Danhong Injections at Different Time-points During the Perioperative Period of Acute Myocardial Infarction: A Systematic Review and Meta-analysis of Randomized Controlled Trials.

Objectives: Danhong injections (DHI) are widely used in the treatment of acute myocardial infarction (AMI). As there are no guidelines for the timing of DHI in the peri-percutaneous coronary intervention (PCI) period for AMI, we investigated the effects of DHI timing. Methods: We reviewed reports published before September 30, 2020 in PubMed, embase, the Cochrane Central Register of Controlled Trials, the Chinese BioMedical database, Chinese VIP database, Wanfang database, and Chinese National Knowledge Infrastructure database. Only randomized controlled trials of DHI with percutaneous coronary intervention for AMI were included. Methodological quality was assessed using the Cochrane evaluation manual 5.3.3 criteria. A meta-analysis was performed, and forest plots were drawn. Results: We included 23 studies which all revealed that patients in DHI groups had better efficacy than control groups. Subgroup analysis revealed that DHI administered intraoperatively and continued postoperatively was more effective in increasing left ventricular ejection fraction when compared to other time-points (p < 0.001). The pre- and intraoperative use of DHI could improve reflow more effectively than conventional treatment, while the effect was not significant in the postoperative intervention study (p = 0.654). The 16 postoperative interventions revealed that the effect of DHI at 14 days was better than that at 7 and 10 days for hs-CRP (p = 0.013), the 10-days treatment produced better results for CK-MB than for the other treatments (p < 0.001) and a dosage of 30 ml proved most effective for IL-6 (p < 0.001). Conclusion: DHI proved to be superior to conventional Western medicine in reducing the incidence of adverse cardiac events, promoting reperfusion, improving cardiac function, reducing inflammatory factors, and protecting the myocardium. DHI should be administered early in the perioperative period and continued postoperatively because of its ability to improve cardiac function. Furthermore, in the PCI postoperative, 30 ml is recommended to inhibit IL-6 levels, for patients with high hs-CRP, a course of 14 days is most effective, for patients with obvious abnormalities of CK-MB, a 10-days course of treatment is recommended. However, due to the limited number and quality of the original randomized controlled trials, our conclusions need large, multi-centre RCTs to validation.

Metabolomics reveals the reproductive abnormality in female zebrafish exposed to environmentally relevant levels of climbazole.

Climbazole (CBZ) ubiquitously detected in the aquatic environment may disrupt fish reproductive function. Thus far, the previous study has focused on its transcriptional impact of steroidogenesis-related genes on zebrafish, but the underlying toxic mechanism still needs further investigation at the metabolic level. In this study, adult zebrafish were chronically exposed to CBZ at concentrations of 0.1 (corresponding to the real concentration in surface water), 10, and 1000 µg/L and evaluated for reproductive function by egg production, with subsequent ovarian tissue samples taken for histology, metabolomics, and other biochemical analysis. After 28 days' exposure, fecundity was significantly decreased in all exposure groups, with the inhibition of oocytes in varying developmental stages to a certain degree. The decrease in retinoic acid and sex hormones, down-regulated genes important in steroidogenesis, and increase in oxidized/reduced glutathione ratio and occurrence of apoptotic cells were observed in zebrafish ovaries following exposure to CBZ even at environmentally realistic concentrations, suggesting that alternations in steroidogenesis and oxidative stress can play significant roles in CBZ-triggered reproductive toxicity. Besides, mass spectrometry imaging analysis validated the results from metabolomics analysis. Our findings provide novel perspectives for unveiling the mechanism of reproductive dysfunction by CBZ and highlight its risk to fish reproduction.

China's practice to prevent and control COVID-19 in the context of large population movement.

BACKGROUND: The emerging infectious disease, coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), poses a serious threat in China and worldwide. Challenged by this serious situation, China has taken many measures to contain its transmission. This study aims to systematically review and record these special and effective practices, in hope of benefiting for fighting against the ongoing worldwide pandemic. METHODS: The measures taken by the governments was tracked and sorted on a daily basis from the websites of governmental authorities (e.g. National Health Commission of the People's Republic of China). And the measures were reviewed and summarized by categorizations, figures and tables, showing an ever-changing process of combating with an emerging infectious disease. The population shift levels, daily local new diagnosed cases, daily mortality and daily local new cured cases were used for measuring the effect of the measures. RESULTS: The practices could be categorized into active case surveillance, rapid case diagnosis and management, strict follow-up and quarantine of persons with close contacts, and issuance of guidance to help the public understand and adhere to control measures, plus prompt and effective high-level policy decision, complete activation of the public health system, and full involvement of the society. Along with the measures, the population shift levels, daily local new diagnosed cases, and mortality were decreased, and the daily local new cured cases were increased in China. CONCLUSIONS: China's practices are effective in controlling transmission of SARS-CoV-2. Considering newly occurred situations (e.g. imported cases, work resumption), the control measures may be adjusted.

Intrathoracic infusion therapy with Lentinan and chemical irritants for malignant pleural effusion: a systematic review and meta-analysis of 65 randomized controlled trials.

BACKGROUND: Aderivative of Shiitake mushrooms, Lentinan is used to control malignant pleural effusion (MPE) through intrathoracic infusion. PURPOSE: To determine the clinical response, survival and safety of Lentinan plus chemical irritants, and the optimal combinations with chemical irritants, indication, threshold and optimal regimen for achieving the desired responses. STUDY DESIGN: We performed a new systematic review and meta-analysis following the PRISMA guidelines. METHODS: We collected all randomized controlled trials (RCTs) regarding Lentinan plus chemical irritants from Chinese and English electronic databases (from inception until March 2019). We evaluated their bias risk, synthesized data using meta-analysis, and summarized evidence quality following the Grades of Recommendation Assessment, Development and Evaluation approach. RESULTS: We included 65 RCTs involving 4,080 patients and nine chemical irritants. Most trials had unclear bias risk. Lentinan with cisplatin significantly improved complete response [Risk ratio (RR) = 1.68, 95% confidence intervals (CI) (1.51 to 1.87), p < 0.00001, Fig.3a] and quality of life [RR = 1.51 95% CI (1.41 to 1.62), p < 0.00001, Fig.4], and decreased the risk of treatment failure, myelosuppression, gastrointestinal reaction, and chest pain. For patients with moderate to large volume of the pleural effusion, primary treatment, KPS score ≥ 50-60, or anticipated survival time ≥ 3months, Lentinan (3-4 mg/time, once a week for three to four times) withcisplatin (30-40 mg/m2 or 50-60 mg/m2) significantly improved complete response and decreased failure. Most results were robust and moderate quality. CONCLUSION: The results suggest that Lentinan with chemical irritants, especially cisplatin is beneficial to the patient with MPE, and provide evidence for the indication, threshold, and optimal regimen that may achieve success and decrease failure.
