Cerebrospinal fluid circulating tumor DNA profiling for risk stratification and matched treatment of central nervous system metastases.

Genomic profiling of central nervous system (CNS) metastases has the potential to guide treatments. In the present study, we included 584 patients with non-small-cell lung cancer and CNS metastases and performed a comprehensive analysis of cerebrospinal fluid (CSF) circulating tumor DNA (ctDNA) with clinicopathological annotation. CSF ctDNA-positive detection was independently associated with shorter survival than negative detection (hazard ratio (HR) = 1.

Efficacy and safety of Qingfei Huatan formula in the treatment of acute exacerbation of chronic obstructive pulmonary disease: A multi-centre, randomised, double-blind, placebo-controlled trial.

Background: Chronic obstructive pulmonary disease (COPD), a common respiratory disease, can be effectively treated by traditional Chinese medicine (TCM). Qingfei Huatan, a TCM formula, has been reported to effectively alleviate the clinical symptoms of COPD patients. However, there is a lack of multi-centre, randomised, double-blind, controlled clinical trials documenting the clinical efficacy and safety of this formula in the treatment of acute exacerbation of COPD (AECOPD).

PERK inhibitor (ISRIB) improves depression-like behavior by inhibitions of HPA-axis over-activation in mice exposed to chronic restraint stress.

Stressful life event is closely associated with depression, thus strategies that blunt or prevent the negative effect stress on the brain might benefits for the treatment of depression. Although previous study showed the role of protein kinase R (PKR)-like ER kinase (PERK) in inflammation related depression, its involvement in the neuropathology of chronic stress induced depression is still unknown. We tried to explore whether block the PERK pathway would alleviate the animals' depression-like behavior induced by chronic restraint stress (CRS) and investigate the underlying mechanism.

Associations between the use of red yeast rice preparations and adverse health outcomes: An umbrella review of meta-analyses of randomized controlled trials.

Objective: This study was designed to evaluate the existing evidence and offer a comprehensive understanding of the associations between the use of RYR preparations and various adverse health outcomes.

Magnolol alleviates pulmonary fibrosis inchronic obstructive pulmonary disease by targeting transient receptor potential vanilloid 4-ankyrin repeat domain.

Transient receptor potential vanilloid 4 (TRPV4) plays a role in regulating pulmonary fibrosis (PF). While several TRPV4 antagonists including magnolol (MAG), have been discovered, the mechanism of action is not fully understood. This study aimed to investigate the effect of MAG on alleviating fibrosis in chronic obstructive pulmonary disease (COPD) based on TRPV4, and to further analyze its mechanism of action on TRPV4.

[Constituent elements and characteristics of ancient acupuncture and moxibustion prescriptions: taking migraine and headache as an example].

The basic constituent elements of ancient acupuncture prescriptions and moxibustion prescriptions for migraine and headache are extracted and summarized. The frequency and proportion of each element are counted and its characteristics are analyzed. The basic constituent elements of ancient acupuncture and moxibustion prescriptions includes five aspects: disease symptoms (main symptoms, concurrent symptoms, etiology and pathogenesis), disease type, acupuncture and moxibustion site (acupoint name, site name, meridian name), manipulation method (acupuncture method, reinforcing and reducing method, blood pricking method, moxibustion method) and curative effect.

Ligustilide attenuates airway remodeling in COPD mice by covalently binding to MH2 domain of Smad3 in pulmonary epithelium, disrupting the Smad3-SARA interaction.

Airway remodeling is one of the hallmarks of chronic obstructive pulmonary disease (COPD) and is closely related to the dysregulation of epithelial-mesenchymal transition (EMT). Smad3, an important transcriptional regulator responsible for transducing TGF-β1 signals, is a promising target for EMT modulation. We found that ligustilide (Lig), a novel Smad3 covalent inhibitor, effectively inhibited airway remodeling in cigarette smoke (CS) combined with lipopolysaccharide (LPS)-induced COPD mice.

[Study on acupoint selection rules for headache based on the earliest recorded literature of ancient acupuncture prescriptions].

Through collecting the prescriptions for headache treated with acupuncture in () till the Qing Dynasty, the literature traceability research is undertaken to determine the extant literature documents with the earliest recorded acupuncture prescriptions and identify the repeated ones in later generations; and then, the acupoint use frequency in the earliest recorded literature of acupuncture prescriptions in the extant documents and acupuncture treatment verses is analyzed separately. It is found that the most of acupoints of high use frequency are overlapped between such two kinds of literature. By integrating and classifying the same or similar contents of acupuncture prescription articles between headache and migraine, the common characteristics and acupoint selections are extracted, the regularity of acupoint selection is explored in view of etiology, complication and affected location, and the attributed fourteen meridians are analyzed statistically in terms of the acupoints in the earliest recorded prescriptions.

[Overview of evaluation methods on efficacy of acupuncture and moxibustion by ancient medical experts].

To sort out and summarize the evaluationmethods on the efficacy by acupuncture and moxibustion in ancient literature. The evaluation methods by ancient medical experts could be divided into two categories: one is according to the change of patient's conditions before and after treatment, including the subjective symptoms, the information getting from the four examination methods in TCM; the other is according to the characteristics of different interventions. For example, evaluating acupuncture by the "arrival of " "getting "; evaluating pricking collaterals-bloodletting therapy by the colour of blood; evaluating moxibustion by the skin colour and the feeling on the suppurated sore.

Diuretic Effect and Metabolomics Analysis of Crude and Salt-Processed Plantaginis Semen.

Plantaginis Semen (PS) is well recognized in traditional Chinese medicine (TCM) and health products. Crude PS (CPS) and salt-processed CPS (SPS) are the two most commonly used decoction pieces of PS, and are included in the 2020 edition of . Although they all have multiple effects, the mechanisms for treating diseases are different and remain unclear, the processing mechanism of SPS is also indeterminate, which hinders their clinical application to a certain extent.

Triglyceride metabolism and angiopoietin-like proteins in lipoprotein lipase regulation.

Hypertriglyceridemia is a risk factor for a series of diseases, such as cardiovascular disease (CVD), diabetes and nonalcoholic fatty liver disease (NAFLD). Angiopoietin-like proteins (ANGPTLs) family, especially ANGPTL3, ANGPTL4 and ANGPTL8, which regulate lipoprotein lipase (LPL) activity, play pivotal roles in triglyceride (TG) metabolism and related diseases/complications. There are many transcriptional and post-transcriptional factors that participate in physiological and pathological regulation of ANGPTLs to affect triglyceride metabolism.

Altered profiles of fecal metabolites correlate with visceral hypersensitivity and may contribute to symptom severity of diarrhea-predominant irritable bowel syndrome.

Background: Fecal metabolites are associated with gut visceral sensitivity, mucosal immune function and intestinal barrier function, all of which have critical roles in the pathogenesis of irritable bowel syndrome (IBS). However, the metabolic profile and pathophysiology of IBS are still unclear. We hypothesized that altered profiles of fecal metabolites might be involved in the pathogenesis of IBS with predominant diarrhea (IBS-D).
