Leonurus japonicus Houtt. modulates neuronal apoptosis in intracerebral hemorrhage: Insights from network pharmacology and molecular docking.

ETHNOPHARMACOLOGICAL RELEVANCE: Leonurus japonicus Houtt. (Labiatae), commonly known as Chinese motherwort, is a herbaceous flowering plant that is native to Asia. It is widely acknowledged in traditional medicine for its diuretic, hypoglycemic, antiepileptic properties and neuroprotection. Currently, Leonurus japonicus (Leo) is included in the Pharmacopoeia of the People's Republic of China. Traditional Chinese Medicine (TCM) recognizes Leo for its myriad pharmacological attributes, but its efficacy against ICH-induced neuronal apoptosis is unclear. AIMS OF THE STUDY: This study aimed to identify the potential targets and regulatory mechanisms of Leo in alleviating neuronal apoptosis after ICH. MATERIALS AND METHODS: The study employed network pharmacology, UPLC-Q-TOF-MS technique, molecular docking, pharmacodynamic studies, western blotting, and immunofluorescence techniques to explore its potential mechanisms. RESULTS: Leo was found to assist hematoma absorption, thus improving the neurological outlook in an ICH mouse model. Importantly, molecular docking highlighted JAK as Leo's potential therapeutic target in ICH scenarios. Further experimental evidence demonstrated that Leo adjusts JAK1 and STAT1 phosphorylation, curbing Bax while augmenting Bcl-2 expression. CONCLUSION: Leo showcases potential in mitigating neuronal apoptosis post-ICH, predominantly via the JAK/STAT mechanism.

Chromatin accessibility and H3K9me3 landscapes reveal long-term epigenetic effects of fetal-neonatal iron deficiency in rat hippocampus.

BACKGROUND: Iron deficiency (ID) during the fetal-neonatal period results in long-term neurodevelopmental impairments associated with pervasive hippocampal gene dysregulation. Prenatal choline supplementation partially normalizes these effects, suggesting an interaction between iron and choline in hippocampal transcriptome regulation. To understand the regulatory mechanisms, we investigated epigenetic marks of genes with altered chromatin accessibility (ATAC-seq) or poised to be repressed (H3K9me3 ChIP-seq) in iron-repleted adult rats having experienced fetal-neonatal ID exposure with or without prenatal choline supplementation. RESULTS: Fetal-neonatal ID was induced by limiting maternal iron intake from gestational day (G) 2 through postnatal day (P) 7. Half of the pregnant dams were given supplemental choline (5.0 g/kg) from G11-18. This resulted in 4 groups at P65 (Iron-sufficient [IS], Formerly Iron-deficient [FID], IS with choline [ISch], and FID with choline [FIDch]). Hippocampi were collected from P65 iron-repleted male offspring and analyzed for chromatin accessibility and H3K9me3 enrichment. 22% and 24% of differentially transcribed genes in FID- and FIDch-groups, respectively, exhibited significant differences in chromatin accessibility, whereas 1.7% and 13% exhibited significant differences in H3K9me3 enrichment. These changes mapped onto gene networks regulating synaptic plasticity, neuroinflammation, and reward circuits. Motif analysis of differentially modified genomic sites revealed significantly stronger choline effects than early-life ID and identified multiple epigenetically modified transcription factor binding sites. CONCLUSIONS: This study reveals genome-wide, stable epigenetic changes and epigenetically modifiable gene networks associated with specific chromatin marks in the hippocampus, and lays a foundation to further elucidate iron-dependent epigenetic mechanisms that underlie the long-term effects of fetal-neonatal ID, choline, and their interactions.

A role for the cerebellum in motor-triggered alleviation of anxiety.

Physical exercise is known to reduce anxiety, but the underlying brain mechanisms remain unclear. Here, we explore a hypothalamo-cerebello-amygdalar circuit that may mediate motor-dependent alleviation of anxiety. This three-neuron loop, in which the cerebellar dentate nucleus takes center stage, bridges the motor system with the emotional system. Subjecting animals to a constant rotarod engages glutamatergic cerebellar dentate neurons that drive PKCδ+ amygdalar neurons to elicit an anxiolytic effect. Moreover, challenging animals on an accelerated rather than a constant rotarod engages hypothalamic neurons that provide a superimposed anxiolytic effect via an orexinergic projection to the dentate neurons that activate the amygdala. Our findings reveal a cerebello-limbic pathway that may contribute to motor-triggered alleviation of anxiety and that may be optimally exploited during challenging physical exercise.

In Vitro and In Vivo Anti-Cancer Activity of Lasiokaurin in a Triple-Negative Breast Cancer Model.

Due to its intricate heterogeneity, high invasiveness, and poor prognosis, triple-negative breast cancer (TNBC) stands out as the most formidable subtype of breast cancer. At present, chemotherapy remains the prevailing treatment modality for TNBC, primarily due to its lack of estrogen receptors (ERs), progesterone receptors (PRs), and human epidermal growth receptor 2 (HER2). However, clinical chemotherapy for TNBC is marked by its limited efficacy and a pronounced incidence of adverse effects. Consequently, there is a pressing need for novel drugs to treat TNBC. Given the rich repository of diverse natural compounds in traditional Chinese medicine, identifying potential anti-TNBC agents is a viable strategy. This study investigated lasiokaurin (LAS), a natural diterpenoid abundantly present in Isodon plants, revealing its significant anti-TNBC activity both in vitro and in vivo. Notably, LAS treatment induced cell cycle arrest, apoptosis, and DNA damage in TNBC cells, while concurrently inhibiting cell metastasis. In addition, LAS effectively inhibited the activation of the phosphatidylinositol-3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR) pathway and signal transducer and activator of transcription 3 (STAT3), thus establishing its potential for multitarget therapy against TNBC. Furthermore, LAS demonstrated its ability to reduce tumor growth in a xenograft mouse model without exerting detrimental effects on the body weight or vital organs, confirming its safe applicability for TNBC treatment. Overall, this study shows that LAS is a potent candidate for treating TNBC.

Syndrome of liver depression and spleen deficiency is a primary TCM syndrome of response to entecavir + FuZheng HuaYu in patients with HBV-related liver fibrosis.

Objective: Although clinical studies have found that Chinese patent medicine FuZheng HuaYu tablet/capsule can promote the reversal of HBV-related liver fibrosis, not all sufferers have histopathological responses. This study aims to explore the correlation between traditional Chinese medicine (TCM) syndromes and response to entecavir + FuZheng HuaYu (ETV + FZHY) in patients with HBV-related liver fibrosis. Methods: This a multi-center cross-sectional study. According to the different treatment strategies that sufferers have ever received, a total of 437 cases were included and divided into ETV + FZHY group and ETV + placebo group. And based on the relevant efficacy determination criteria, the two groups were subdivided into efficacy responders and non-responders. Then, TCM clinical questionnaire information of these patients were collected for subsequent analysis to acquire relevant syndrome elements and TCM syndromes. Results: No matter what group was, the first three frequency of TCM pathological position in efficacy responders were as follows: Liver > Spleen > Stomach (TCM concepts). As for the ETV + FZHY group, the first three frequency of pathological nature was ranked as Qi deficiency > Dampness > Heat. Compared with the non-responders, the frequency of Spleen, Stomach, Qi deficiency, Heat, and Qi movement stagnation was significantly increased in the efficacy responders (P < 0.05). In terms of TCM syndromes, the frequency increase of Syndrome of liver depression and spleen deficiency (LDSD), in the efficacy responders, changed more obviously than the non-responders (Chi2 = 6.32, P = 0.0006). Conclusions: TCM syndrome elements of Spleen, Stomach, Qi deficiency, Heat, and Qi movement stagnation were closely associated with efficacy responders with HBV-related liver fibrosis in the ETV + FZHY group. Moreover, LDSD was a primary TCM syndrome in these responders.

Xylomolins O-X: New limonoids from the Thai mangrove Xylocarpus moluccensis.

Ten new limonoids, named xylomolins O-X, were isolated from seeds of the mangrove Xylocarpus moluccensis, collected in the mangrove swamp of Trang Province, Thailand. Their structures were elucidated on the basis of comprehensive spectroscopic data analysis. The absolute configurations of five compounds (1, 3, 8-10) were unequivocally determined by single-crystal X-ray diffraction analyses, conducted with Cu Kα radiation. Xylomolins OU (1-7) are structurally intriguing mexicanolides, and xylomolin V (8) is a derivative of azadirone. Xylomolin W (9) is the first phragmalin 1,8,9-orthoester with report on X-ray crystallography from the genus Xylocarpus. In addition, xylomolin X (10) is the fifth member of the khayalactone class of limonoids with a hexahydro-2H-2,5-propanocyclopenta[b]furan motif. Compounds 1-10 inhibited NO production in LPS-activated RAW 264.7 macrophages in the range of 10.45-95.47% at the concentration of 100.0 µM. Xylomolin X (10) and xylomolin V (8), exhibited the most potent activity with IC50 values of 9.90 ± 1.84 µM and 14.66 ± 2.33 µM, respectively.

Mupirocin enhances the biofilm formation of Staphylococcus epidermidis in an atlE-dependent manner.

The pathogenicity of Staphylococcus epidermidis is largely attributed to its exceptional ability to form biofilms. Here, we report that mupirocin, an antimicrobial agent widely used for staphylococcal decolonization and anti-infection, strongly stimulates the biofilm formation of S. epidermidis. Although the polysaccharide intercellular adhesin (PIA) production was unaffected, mupirocin significantly facilitated extracellular DNA (eDNA) release by accelerating autolysis, thereby positively triggering cell surface attachment and intercellular agglomeration during biofilm development. Mechanistically, mupirocin regulated the expression of genes encoding for the autolysin AtlE as well as the programmed cell death system CidA-LrgAB. Critically, through gene knockout, we found out that deletion of atlE, but not cidA or lrgA, abolished the enhancement of biofilm formation and eDNA release in response to mupirocin treatment, indicating that atlE is required for this effect. In Triton X-100 induced autolysis assay, mupirocin treated atlE mutant displayed a slower autolysis rate compared with the wild-type strain and complementary strain. Therefore, we concluded that subinhibitory concentrations of mupirocin enhance the biofilm formation of S. epidermidis in an atlE dependent manner. This induction effect could conceivably be responsible for some of the more unfavourable outcomes of infectious diseases.

[Active components and mechanism of Jinwugutong Capsules in treatment of osteoporosis: a study based on UPLC-Q-Exactive-MS/MS combined with network pharmacology].

UPLC-Q-Exactive-MS/MS and network pharmacology were employed to preliminarily study the active components and mechanism of Jinwugutong Capsules in the treatment of osteoporosis. Firstly, UPLC-Q-Exactive-MS/MS was employed to characterize the chemical components of Jinwugutong Capsules, and network pharmacology was employed to establish the "drug-component-target-pathway-disease" network. The key targets and main active components were thus obtained. Secondly, AutoDock was used for the molecular docking between the main active components and key targets. Finally, the animal model of osteoporosis was established, and the effect of Jinwugutong Capsules on the expression of key targets including RAC-alpha serine/threonine-protein kinase(AKT1), albumin(ALB), and tumor necrosis factor-alpha(TNF-α) was determined by enzyme-linked immunosorbent assay(ELISA). A total of 59 chemical components were identified from Jinwugutong Capsules, among which coryfolin, 8-prenylnaringenin, demethoxycurcumin, isobavachin, and genistein may be the main active components of Jinwugutong Capsules in treating osteoporosis. The topological analysis of the protein-protein interaction(PPI) network revealed 10 core targets such as AKT1, ALB, catenin beta 1(CTNNB1), TNF, and epidermal growth factor receptor(EGFR). The Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment showed that Jinwugutong Capsules mainly exerted the therapeutic effect by regulating the phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT) signaling pathway, neuroactive ligand-receptor interaction, mitogen-activated protein kinase(MAPK) signaling pathway, Rap1 signaling pathway and so on. Molecular docking showed that the main active components of Jinwugutong Capsules well bound to the key targets. ELISA results showed that Jinwugutong Capsules down-regulated the protein levels of AKT1 and TNF-α and up-regulated the protein level of ALB, which preliminarily verified the reliability of network pharmacology. This study indicates that Jinwugutong Capsules may play a role in the treatment of osteoporosis through multiple components, targets, and pathways, which can provide reference for the further research.

Effects of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy treatment in patients with untreated gastric cancer with peritoneal metastasis / 中华胃肠外科杂志

Objective: To investigate the efficacy of laparoscopic hyperthermic intraperitoneal perfusion chemotherapy combined with intraperitoneal and systemic chemotherapy (HIPEC-IP-IV) in the treatment of peritoneal metastases from gastric cancer (GCPM). Methods: This was a descriptive case series study. Indications for HIPEC-IP-IV treatment include: (1) pathologically confirmed gastric or esophagogastric junction adenocarcinoma; (2) age 20-85 years; (3) peritoneal metastases as the sole form of Stage IV disease, confirmed by computed tomography, laparoscopic exploration, ascites or peritoneal lavage fluid cytology; and (4) Eastern Cooperative Oncology Group performance status 0-1. Contraindications include: (1) routine blood tests, liver and renal function, and electrocardiogram showing no contraindications to chemotherapy; (2) no serious cardiopulmonary dysfunction; and (3) no intestinal obstruction or peritoneal adhesions. According to the above criteria, data of patients with GCPM who had undergone laparoscopic exploration and HIPEC from June 2015 to March 2021 in the Peking University Cancer Hospital Gastrointestinal Center were analyzed, after excluding those who had received antitumor medical or surgical treatment. Two weeks after laparoscopic exploration and HIPEC, the patients received intraperitoneal and systemic chemotherapy. They were evaluated every two to four cycles. Surgery was considered if the treatment was effective, as shown by achieving stable disease or a partial or complete response and negative cytology. The primary outcomes were surgical conversion rate, R0 resection rate, and overall survival. Results: Sixty-nine previously untreated patients with GCPM had undergone HIPEC-IP-IV, including 43 men and 26 women; with a median age of 59 (24-83) years. The median PCI was 10 (1-39). Thirteen patients (18.8%) underwent surgery after HIPEC-IP-IV, R0 being achieved in nine of them (13.0%). The median overall survival (OS) was 16.1 months. The median OS of patients with massive or moderate ascites and little or no ascites were 6.6 and 17.9 months, respectively (P<0.001). The median OS of patients who had undergone R0 surgery, non-R0 surgery, and no surgery were 32.8, 8.0, and 14.9 months, respectively (P=0.007). Conclusions: HIPEC-IP-IV is a feasible treatment protocol for GCPM. Patients with massive or moderate ascites have a poor prognosis. Candidates for surgery should be selected carefully from those in whom treatment has been effective and R0 should be aimed for.

Leukocyte and Platelet-Rich Plasma (L-PRP) in Tendon Models: A Systematic Review and Meta-Analysis of in vivo/in vitro Studies.

Purpose: To perform a systematic review on the application of leukocyte- and platelet-rich plasma (L-PRP) in tendon models by reviewing in vivo/in vitro studies. Methods: The searches were performed via electronic databases including PubMed, Embase, and Cochrane Library up to September 2022 using the following keywords: ((tenocytes OR tendon OR tendinitis OR tendinosis OR tendinopathy OR tendon injury) AND (platelet-rich plasma OR PRP OR autologous conditioned plasma OR leukocyte- and platelet-rich plasma OR L-PRP OR leukocyte-richplatelet-rich plasma Lr-PRP)). Only in vitro and in vivo studies that assessed the potential effects of L-PRP on tendons and/or tenocytes are included in this study. Description of PRP, study design and methods, outcomes measured, and results are extracted from the data. Results: A total of 17 studies (8 in vitro studies and 9 in vivo studies) are included. Thirteen studies (76%) reported leukocyte concentrations of L-PRP. Four studies (24%) reported the commercial kits. In in vitro studies, L-PRP demonstrated increased cell proliferation, cell migration, collagen synthesis, accelerated inflammation, and catabolic response in the short term. In addition, most in vivo studies indicated increased collagen type I content. According to in vivo studies reporting data, L-PRP reduced inflammation response in 71.0% of studies, while it enhanced the histological quality of tendons in 67.0% of studies. All 3 studies reporting data found increased biomechanical properties with L-PRP treatment. Conclusions: Most evidence indicates that L-PRP has some potential effects on tendon healing compared to control. However, it appears that L-PRP works depending on the biological status of the damaged tendon. At an early stage, L-PRP may accelerate tendon healing, but at a later stage, it could be detrimental.

CASE SUMMARY: We report a case of a 61-year-old male with aconitine poisoning presenting with malignant arrhythmia and severe cardiogenic shock, which was successfully managed with aggressive advanced life support and heart transplantation. CONCLUSION: This is the first case wherein in vivo cardiac pathology was obtained, confirming that aconitine caused acute myocardial necrosis.

Molecular Mechanism of YuPingFeng in the Treatment of Asthma Based on Network Pharmacology and Molecular Docking Technology.

Objective: To explore the molecular targets and mechanism of YuPingFeng (YPF) for the treatment of asthma by using network pharmacology and molecular docking. Methods: The potential active ingredients and relevant targets of YPF were obtained from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Asthma-related gene targets were retrieved from GeneCards, OMIM, DrugBank, PharmGKB, and TTD databases. The protein-protein (PPI) network between YPF and asthma common targets was constructed by SRING online database and Cytoscape software. GO and KEGG analyses were performed to explore the complicated molecular biological processes and potential pathways. Finally, a molecular docking approach was carried out to verify the results. Results: We obtained 100 potential targets of the 35 active ingredients in YPF and 1610 asthma-related targets. 60 YPF-asthma common targets were selected to perform PPI analysis. Seven core genes were screened based on two topological calculation methods. GO and KEGG results showed that the main pathways of YPF in treating asthma include TNF signaling pathway and PI3K-Akt signaling pathway. Finally, the molecular docking results indicated that the key ingredients of YPF had a good affinity with the relevant core genes. Conclusion: This study reflects the multicomponent, multitarget, and multipathway characteristics of YPF in treating asthma, providing a theoretical and scientific basis for the intervention of asthma by traditional Chinese medicine YPF.

[Research strategies and methods for precious animal medicine substitutes].

Animal medicine is a large category of Chinese medicinecommonly used in clinical practice and has important scientific and therapeutic value. Animal medicine isscarcer than herbal medicine. In recent years, with the vigorous development of traditional Chinese medicine(TCM),the contradiction between the increasing industrial demand andsupply of scarce and even endangered medicinal animals has become increasingly prominent. The continuous lack of medicinal animal resources affects the clinical demandandalso causes serious damage to the ecological environment. Only relying on artificial breeding is not enough to alleviate the current condition of depletion. In the face of this dilemma, it is a major challenge for the current industrial development to protect animal resources and meet clinical and industrial needs with "available medicines". The application of substitutes for animal medicines isthe key focus to alleviate this problem, and it is also the key scientific issue to be solved urgently in the modernization of TCM. This paper summarizedand reviewedthe history, current situation, strategies, and methods of animal medicinesubstitution and put forward the point of view of "similar chemical characteristics, similar efficacy, and higher safety" to provide references for scientific substitution and resource protection of rare animals.

Guanxinning tablet inhibits the interaction between leukocyte integrin Mac-1 and platelet GPIbα for antithrombosis without increased bleeding risk.

Recent studies have showed that thrombosis is closely related to leucocytes involved in immunity. Interfering with the binding of leukocyte integrin Mac-1 and platelet GPIbα can inhibit thrombosis without affecting physiological coagulation. Mac-1-GPIbα is proposed as a potential safety target for antithrombotic agents. Guanxinning tablet (GXNT) is an oral Chinese patent medicine used for the treatment of angina pectoris, which contains phenolic acid active ingredients, such as salvianolic acids, ferulic acid, chlorogenic acid, caffeic acid, rosmarinic acid, tanshinol, and protocatechualdehyde. Our previous studies demonstrated that GXN exhibited significant antithrombotic effects, and clinical studies suggested that it did not increase bleeding risk. In addition, GXN exerted a significantly regulatory effect on immune inflammation. In the current study, we intended to evaluate the effects of GXN on bleeding events and explore the safety antithrombotic mechanism of GXN based on leukocyte-platelet interaction. First, we established a gastric ulcer model induced by acetic acid in rats and found that GXN not only did not increase the degree of gastrointestinal bleeding when gastric ulcer occurred, but also had a certain promoting effect on the healing of gastric ulcer. Second, in vitroexperiments showed that after pretreatment with GXN and activation by phorbol 12-myristate-13-acetate (PMA), the adhesion and aggregation of leukocytes with human platelets were reduced. It was also found that GXN reduced the expression and activation of Mac-1 in leucocytes, and inhibited platelet activation due to leukocyte engagement via Mac-1. Overall, the results suggest that GXN may be a safe antithrombotic agent, and its low bleeding risk mechanism is probably related to inhibited leukocyte-platelet aggregation and its interaction target Mac-1-GPIbα.

Exploring the dynamic of microbial community and metabolic function in food waste composting amended with traditional Chinese medicine residues.

The aim of this study was to explore the dynamic of microbial community and metabolic function in food waste composting amended with traditional Chinese medicine residues (TCMRs). Results suggested that TCMRs addition at up to 10% leads to a higher peak temperature (60.5 °C), germination index (GI) value (119.26%), and a greater reduction in total organic carbon (TOC) content (8.08%). 10% TCMRs significantly induced the fluctuation of bacterial community composition, as well as the fungal community in the thermophilic phase. The addition of 10% TCMRs enhanced the abundance of bacterial genera such as Acetobacter, Bacillus, and Brevundimonas, as well as fungal genera such as Chaetomium, Thermascus, and Coprinopsis, which accelerated lignocellulose degradation and humification degree. Conversely, the growth of Lactobacillus and Pseudomonas was inhibited by 10% TCMRs to weaken the acidic environment and reduce nitrogen loss. Metabolic function analysis revealed that 10% TCMRs promoted the metabolism of carbohydrate and amino acid, especially citrate cycle, glycolysis/gluconeogenesis, and cysteine and methionine metabolism. Redundancy analysis showed that the carbon to nitrogen (C/N) ratio was the most significant environmental factor influencing the dynamic of bacterial and fungal communities.

Insight into the microbial mechanisms for the improvement of composting efficiency driven by Aneurinibacillus sp. LD3.

This work explored the microbial mechanisms for the improvement of composting efficiency driven by thermotolerant lignin-degrading bacterium Aneurinibacillus sp. LD3 (LD3). Results showed that LD3 inoculant prolonged the thermophilic period by 4 days, improved the final content of humic acid, total phosphorus (TP), nitrogen, potassium and seed germination index. Inoculating LD3 enhanced the relative abundance of thermotolerant and phosphate-solubilizing microbes including the phyla of Proteobacteria, Bacteroidota, Firmicutes, and Actinobacteriota, and the genus of Bacillus, Thermoactinomyces, and Pseudomonas. Metabolic function analysis showed that sequences involved in carbohydrate and amino acid metabolism were boosted, while sequences associated with human disease were reduced after inoculating LD3. Spearman correlation analysis revealed that Aneurinibacillus has a significant positive correlation with temperature, TP, Bacillus, and Thermoactinomyces. This study provides useful information for understanding the microbial mechanisms of LD3 promoting composting efficiency, and reveals the tremendous potential of LD3 in the resource utilization of organic solid wastes.

Evaluation of the Safety and Efficacy of Xiao Yao San as a Treatment for Anxiety: A Systematic Review and Meta-Analysis.

Objective: Xiaoyao San (XYS) is a medicinal preparation that is commonly employed in China for the treatment of anxiety disorders (AD). Despite suggestions that it may offer certain advantages in this context, there are no reliable evidence-based studies regarding its efficacy at present. The present study was developed to gauge the efficacy and safety of XYS for the treatment of AD in a systematic manner. Methods: PubMed, the Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Wanfang database, Weipu database, and China Biomedical Documentation Service System (CBM) databases were systematically searched for all randomized control trials (RCTs) evaluating the use of XYS for the treatment of AD published as of November 2021. Two investigators independently screened all studies, extracted data, and assessed the risk of bias for included studies using RevMan5.3. Results: In total, 9 RCTs incorporating 809 patients were included in the present meta-analysis, of which 3 compared oral XYS to anxiolytic treatment and 6 compared oral XYS + anxiolytics to anxiolytic treatment alone. The resultant meta-analysis revealed that XYS alone or in combination with anxiolytic treatment was associated with better improvements in anxiety-related symptoms and reduced adverse drug-related reactions as compared to anxiolytic treatment alone. Conclusion: The available evidence suggests that oral XYS alone or in combination with anxiolytic agents is more effective and safer than anxiolytic treatment alone when used for the treatment of AD. However, owing to the limited number and quality of the studies included in this analysis, further high-quality research will be essential to validate these results.

Effects of n-6 PUFA-rich soybean oil, MUFA-rich olive oil and camellia seed oil on weight and cardiometabolic profiles among Chinese women: a 3-month double-blind randomized controlled-feeding trial.

Previous studies have suggested that replacing saturated fat with unsaturated fat is beneficial for cardiometabolic health. However, research that directly compares the effects of polyunsaturated fatty acids (PUFAs) and monounsaturated fatty acids (MUFAs) is rare. The present 3-month, three-arm, randomized, controlled-feeding trial aimed to investigate the effects of n-6 PUFA- and MUFA-rich cooking oils on body weight and cardiometabolic profiles among middle-aged and elderly Chinese women at high cardiovascular risk. Ninety participants were recruited and randomly assigned to groups fed diets using n-6 PUFA-rich soybean oil (SO, n = 30), MUFA-rich olive oil (OO, n = 30), and MUFA-rich camellia seed oil (CSO, n = 30) as cooking oils considering traditional Chinese eating habits for 3 months. Participants were required to eat only the foods provided for lunch and dinner, and avoid intake of edible oils in breakfast. Body weight and cardiovascular profiles were measured at the baseline, middle, and end of the intervention, and group differences in changes of outcomes during intervention were examined by a linear mixed model. We found no significant difference in the changes of body weight among the SO group (mean change, 0.31 kg; 95% CI, -0.88 to 0.27), the OO group (mean change, -0.13 kg; 95% CI, -0.62 to 0.36), and the CSO group (mean change, -0.72 kg; 95% CI, -1.38 to -0.07). For secondary outcomes, the OO group showed a slight increase in HDL cholesterol (P = 0.03), while the CSO group showed greater reduction in aspartate aminotransferase (AST) (P = 0.02) when compared with the SO group. These results suggested that MUFA-rich OO and CSO exerted more favorable effects on cardiometabolic profiles among middle-aged and elderly Chinese women at high cardiovascular risk than the n-6 PUFA-rich SO.

Sex differences in the pharmacokinetics and tissue residues of Macleaya cordata extracts in rats.

Macleaya cordata extracts (MCE) are listed as feed additives in animal production by the European Food Authority. The core components of MCE are mainly sanguinarine (SA) and chelerythrine (CHE). This study aims to investigate sex differences in the pharmacokinetics and tissue residues of MCE in rats.Male and female rates were intragastrically administered MCE (1.25 mg·kg-1 body weight and 12.5 mg·kg-1 body weight dose for 28 days). SA and CHE concentrations were determined using high-performance liquid chromatography/tandem mass spectrometry.The peak plasma concentration (Cmax) and area under the curve (AUC) of both CHE and SA were higher in female than in male rats (12.5 mg·kg-1 body weight group), whereas their half-life (T1/2) and apparent volume of distribution (Vd) was lower (p < 0.05). Tissue rfesidue analysis indicated that SA and CHE were more distributed in male than in female rats and were highly distributed in the caecum and liver. SA and CHE were completely eliminated from the liver, kidney, lung, heart, spleen, leg muscle, and caecum after 120 h, indicating they did not accumulate in rats for a long time.Overall, we found that the pharmacokinetics and tissue residues of SA and CHE of male and female rats showed sex differences.

The Effect of Sodium Thiosulfate on Coronary Artery Calcification in Hemodialysis Patients.

This study aimed to effectively control the disease process of hemodialysis outpatients. Hemodialysis secondary hyperparathyroidism patients were randomly divided into the control group and treatment group. The control group was treated with routine treatment, and the treatment group was treated with sodium thiosulfate based on the control group. The changes of serum calcium, phosphorus, whole parathyroid hormone, calcium-phosphorus product and coronary artery calcification (CAC) score, as well as the relief of clinical symptoms, postoperative complications and recurrence in the preoperative and postoperative periods were observed. The levels of C-reactive protein and CAC scores were significantly decreased in the treatment group after treatment. While there was no significant difference in blood calcium, blood phosphorus, PTH, calcium-phosphorus product, and CAC score in the control group after treatment. And after treatment, the proportion of skin pruritus, myasthenia, bone pain, insomnia, restless legs syndrome, and other symptoms in the treatment group was significantly decreased compared with those before treatment, but there was no significant change in the control group before and after treatment. Sodium thiosulfate can reduce the high level of CAC in hemodialysis patients obviously.
