Glyphosate exposure affected longevity-related pathways and reduced survival in asian honey bees (Apis cerana).

Glyphosate (N-(phosphonomethyl)glycine, GLY) ranks among the most extensively used and effective herbicides globally. However, excessive GLY utilization poses a substantial threat to the survival of honey bees (Apis cerana). Here we monitored the survival status of A. cerana treated with GLY, and conducted transcriptome sequencing of the bee gut and head to further explore potential GLY influences at the molecular level. We observed that the mortality rate of bees increased as GLY concentration escalated. Pivotal pathways emerged in response to the GLY treatment, with a substantial number of differentially expressed genes enriched in the longevity regulating pathway - multiple species. This strongly suggested that GLY may influence the physiological behavior of bees by impacting this particular pathway. Moreover, our analysis revealed a notable reduction in the enzymatic activities of CYP450 and AChE in both the bee head and intestines of when exposed to GLY. Conversely, the enzymatic activity of superoxide dismutase (SOD) in the head remained unaffected, whereas in the intestines, it exhibited a significant increase. Additionally, prophenol oxidase (PPO) and glutathione-S-transferases (GSTs) displayed contrasting trends in enzymatic activity in both organs. This study offers valuable insights into how GLY impacted the survival of A. cerana.

Effect of Dangfei Liganning capsule on liver X receptor α/steroid regulatory element binding protein-1/fatty acid synthase signal pathway in rats with metabolic- associated fatty liver disease.

OBJECTIVE: To study the mechanism of Dangfei Liganning capsule in the treatment of rats with metabolic associated fatty liver disease (MAFLD). METHODS: Totally 48 specific pathogen free Sprague-Dawley male rats were randomly divided into normal Group, model group, Dangfei Liganning high, moderate, and low-dose groups and Essentiale group which were fed with high fat diet for 8 weeks, and gavage and molding were carried out simultaneously. Dangfei Liganning high, middle and low-dose group were given 0.27, 0.135 and 0.0675 g·kg·d respectively by gavage, Essentiale group was given 0.123 g·kg·d by gavage, the same amount of distilled water was given by gavage in the normal group and the model group. The rats were weighed at the 0th week, 2nd week, 4th week, 6th week and 8th weekend respectively. The rats were sacrificed at the end of the 8th week. Serum levels of alanine aminotransferase (ALT), alanine aminotransferase (AST), triglyceride (TG), total cholesterol (CHO), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein (LDL-C), total protein (TP), albumin (Alb), globulin (GLB), total bilirubin (TBIL), direct bilirubin (DBIL), tumor necrosis factor-α(TNF-α) and interleukin-6 (IL-6) were measured. The levels of liver tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6) and liver pathology [hematoxylin and eosin (HE) staining, oil red O staining] were detected. The expression levels of liver X receptor α (LXRα), steroid regulatory element binding protein-1 (SREBP-1) and fatty acid synthase (FAS) were detected by immunohistochemistry, Western blot and reverse transcription-polymerase chain reaction reverse transcription-polymerase chain reaction. RESULTS: From the beginning to the 8th week, the growth rate of body weight in the Dangfei Liganning high-dose group was slower than all other groups. There was no significant difference in ALB level in all groups ( 0.05). Compared with the model group, the levels of ALT, AST, LDL-C, TG, CHO, TP, GLB, TBIL, DBIL, IL-6, TNF-α were significantly decreased and HDL-C were significantly increased in Dangfei Liganning high-dose group (0.01, < 0.05). HE and oil red O staining showed that the fatty lesions in rat liver were alleviated, while the expressions of LXRα, SREBP-1, FAS mRNA and protein were significantly decreased (0.01). CONCLUSIONS: Dangfei Liganning capsule can slow down the increase of body weight of MAFLD rats, reduce the levels of transaminase, Lipid and inflammatory factors in MAFLD rats, promote the synthesis of liver protein and bile metabolism, and improve the liver fatty lesion of MAFLD rats, among which the Dangfei Liganning high-dose group is more effective. The mechanism of action may be through blocking LXR-SREBP-1-FAS signal pathway.

METHODS: The models of AUB were established by incomplete drug abortion with mifepristone and misoprostol in pregnant rats. The therapeutic effects of decoctions made by eight different weight ratios of Qiancao () and Haipiaoxiao () were observed. RESULTS: Statistical analysis revealed that the most effective weight ratio of Qiancao () and Haipiaoxiao () to treat AUB in this study was 2∶1. CONCLUSION: The insights gained from this study would improve understanding of the mechanisms involved in the effect of Qiancao () and Haipiaoxiao () on AUB.

Sterile alpha motif and histidine-aspartic acid domain-containing protein 1 expression and its relationship with T cell activation in human immunodeficiency virus/acquired immune deficiency syndrome patients with lung-spleen deficiency syndrome pattern.

OBJECTIVE: To investigate the relationship between antiviral restriction factor Sterile Alpha Motif and Histidine-Aspartic acid domain-containing protein 1 (SAMHD1) expression and T cell activation, furthermore, identifying objective indexes of lung-spleen deficiency symptom pattern. METHODS: We assessed the profile of T lymphocyte subsets, characteristics of SAMHD1 and human leukocyte antigen DR (HLA-DR) expression in lung-spleen deficiency patients. At the same time, people living with human immunodeficiency virus / acquired immune deficiency syndrome (HIV/AIDS) (PLWHA) without obvious clinical symptoms and healthy donors in this area were used as controls. RESULTS: Immunohematologic indexes lower CD4 count, lower CD4/CD8 ratio and higher SAMHD1 level were found in lung-spleen deficiency patients. Furthermore, we demonstrated a positive relationship between SAMHD1 and HLA-DR level as well as with interferon factor in lung-spleen deficiency syndrome and patients without obvious clinical signs and symptoms groups. CONCLUSIONS: These data indicated the positive relationship between SAMHD1 and T cell activation which further elucidated the role of SAMHD1 in cellular immune response. Furthermore, combination of T lymphocyte subsets counts and SAMHD1 level may be used as clinical and biological reference basis for the differentiation and diagnosis of HIV / AIDS traditional Chinese medicine syndromes.

[Network Meta-analysis of Huoxue Huayu Chinese medicine injections on hypertensive nephropathy].

To assess the clinical efficacy of Huoxue Huayu Chinese medicine injections on hypertensive nephropathy by using Network Meta-analysis method. The relative randomized controlled trials(RCTs) of Huoxue Huayu Chinese medicine injections on hypertensive nephropathy were retrieved from CNKI, WanFang, VIP, SinoMed, PubMed, Cochrane Library and Web of Science in November 2019. Two researchers independently conducted literature screening, data extraction and quality evaluation. The data was analyzed by RevMan 5.3, Stata 15.1, ADDIS 1.16.8 software. Finally, 4 518 patients in 50 RCTs were included, involving 5 kinds of Huoxue Huayu Chinese medicine injections. The five Chinese medicine injections were Breviscapine Injection, Danhong Injection, Sodium Tanshinone Ⅱ_A Sulfonate Injection, Ginkgo Dipyridamole Injection, and Salvianolate Injection. Meta-analysis showed that, in terms of renal function protection, urine protein quantification and serum creatinine of each Chinese medicine injections combined with conventional Western medicine group, except Salvianolate Injection combined with conventional Western medicine group, was significantly lower than those of the conventional Western medicine treatment group. Ginkgo Dipyridamole Injection combined with conventional Western medicine had the best effect in reducing urine protein, and Danhong Injection combined with conventional Western medicine had the best effect in reducing serum creatinine. In terms of blood pressure control, the blood pressure of each Chinese medicine injections combined with conventional Western medicine group, except Breviscapine Injection combined with conventional Western medicine group, was significantly lower than that of conventional Western medicine treatment group. Salvianolate Injection combined with conventional Western medicine had the best effect in reducing blood pressure. In terms of safety, no serious adverse reactions were found in all studies. The five kinds of Huoxue Huayu Chinese medicine injections combined with conventional Western medicine had significantly advantages in the treatment of hypertensive nephropathy. Ginkgo Dipyridamole Injection combined with conventional Western medicine is most likely to be the optimal therapy. However, limited by the quantity and quality of the documents included, the conclusion of this study still needs to be verified by more high-quality, multi-center and large-sample RCT.

The relationship between soluble CD40 ligand level and atherosclerosis in white-coat hypertension.

This study was designed to examine the distribution of plasma soluble CD40 ligand (sCD40L), and its relationship with carotid intima-media thickness (CIMT) in healthy controls and subjects with white-coat hypertension (WCH) or hypertension (HT). Thirty-five patients with HT, 35 patients with WCH, and 35 healthy controls were enrolled. The normal group (CIMT < 0.9 mm), subclinical atherosclerosis group (0.9 mm ≤ CIMT < 1.2 mm) and atherosclerosis group (CIMT ≥ 1.2 mm) were grouped based on the value of CIMT. The highest level of sCD40L was observed in HT group, followed by WCH group and healthy controls. The level of sCD40L was significantly increased in atherosclerosis group compared with subclinical atherosclerosis group and healthy controls. In the WCH group, sCD40L level was significantly and positively correlated with CIMT and systolic blood pressure. Multiple logistic regression indicated that sCD40L was a risk factor for increased CIMT (odds ratio, 1.504; 95% confidence interval, 1.054-1.956, P < 0.001). The data provided evidence that sCD40L levels in subjects with WCH and HT were significantly and consistently higher than those in healthy controls. SCD40L may represent a potential non-invasive atherosclerosis marker in WCH patients.
