ABSTRACT

Objective@#Several COVID-19 patients have overlapping comorbidities. The independent role of each component contributing to the risk of COVID-19 is unknown, and how some non-cardiometabolic comorbidities affect the risk of COVID-19 remains unclear.@*Methods@#A retrospective follow-up design was adopted. A total of 1,160 laboratory-confirmed patients were enrolled from nine provinces in China. Data on comorbidities were obtained from the patients' medical records. Multivariable logistic regression models were used to estimate the odds ratio ( @*Results@#Overall, 158 (13.6%) patients were diagnosed with severe illness and 32 (2.7%) had unfavorable outcomes. Hypertension (2.87, 1.30-6.32), type 2 diabetes (T2DM) (3.57, 2.32-5.49), cardiovascular disease (CVD) (3.78, 1.81-7.89), fatty liver disease (7.53, 1.96-28.96), hyperlipidemia (2.15, 1.26-3.67), other lung diseases (6.00, 3.01-11.96), and electrolyte imbalance (10.40, 3.00-26.10) were independently linked to increased odds of being severely ill. T2DM (6.07, 2.89-12.75), CVD (8.47, 6.03-11.89), and electrolyte imbalance (19.44, 11.47-32.96) were also strong predictors of unfavorable outcomes. Women with comorbidities were more likely to have severe disease on admission (5.46, 3.25-9.19), while men with comorbidities were more likely to have unfavorable treatment outcomes (6.58, 1.46-29.64) within two weeks.@*Conclusion@#Besides hypertension, diabetes, and CVD, fatty liver disease, hyperlipidemia, other lung diseases, and electrolyte imbalance were independent risk factors for COVID-19 severity and poor treatment outcome. Women with comorbidities were more likely to have severe disease, while men with comorbidities were more likely to have unfavorable treatment outcomes.

ABSTRACT

Rotavirus (RV) infection of human body is mainly colonized in human intestinal epithelial cells, which results in small intestinal epithelial cell damage, and then induces diarrhea, fever and other symptoms. It is one of the most common causes of infantile diarrhea. Toll-like receptors (TLRs), as a kind of pattern recognition receptors, play an important role in the host immune system after virus infection. After different viruses infect human body, various pathogens trigger the host immune response through TLRs, induce the release of various cytokines, and stimulate a series of inflammatory reactions, such as fever, cough and diarrhea, which may further lead to more serious adverse consequences. According to the findings, the anti-inflammatory and anti-viral mechanisms of various effective drugs developed for different pathogens may be closely related to the intervention of TLRs signaling pathway and the regulation of immune response. A large number of studies have shown that rotavirus infection can induce inflammation by affecting the expressions of related proteins and genes in Toll-like receptor 3 (TLR3) and Toll-like receptor 4 (TLR4) signal transduction pathways, stimulating the release of inflammatory cytokines and inducing inflammatory response. Some studies on the mechanism of drug treatment for rotavirus diarrhea also started with TLRs, but only a few clinical and experimental studies on traditional Chinese medicine(TCM) and rotavirus diarrhea involve TLRs signaling pathway. Therefore, this article will focus on the relationship between TLRs signaling pathway and different viral infections, especially with rotavirus infection, in three aspects:viral infection and TLRs signaling pathway, RV infection and TLRs signaling pathway, and the research of traditional Chinese medicine in the treatment of rotavirus diarrhea, in order to guide the clinical and experimental studies on the treatment of rotavirus diarrhea with TCM based on TLR3 and TLR4 signaling pathways.

ABSTRACT

Chronic obstructive pulmonary disease (COPD) is a common respiratory disease with a high morbidity, disability and mortality. At the same time, COPD is always accompanied by pulmonary hypertension, pulmonary fibrosis, chronic pulmonary heart disease, right heart failure and other common serious complications. All of these cause serious financial burden for the family of patients. Airway remodeling plays an important role in the pathogenesis of COPD. It is the progressive development of airflow restriction that induces the main symptoms of COPD, such as cough, asthma and depression. Therefore, it is of great research value to explore the intervention of traditional Chinese medicine(TCM) in the development of COPD by alleviating airway remodeling. Studies have shown that multiple signaling pathways can induce progressive airway remodeling, and the therapeutic effect of TCM has been frequently confirmed by experimental studies. TCM often has a therapeutic effect on COPD through multi-target and multi-channel mediation. This paper mainly includes five signaling pathways that traditional Chinese medicine can intervene COPD airway remodeling, namely matrix metalloproteinases (MMPs)/tissue inhibitors of metalloproteinase (TIMPs), transforming growth factor (TGF)-beta 1/Smads, RhoA/Rho-associated kinase (ROCK), vascular endothelial growth factor (VEGF)/b-fibroblast growth factor (b-FGF) and nuclear factor (NF)-κB. This paper briefly reviews the research progress of these five signaling pathways, and discusses other signaling pathways that may be involved, in order to provide reference and ideas for future experimental research.

ABSTRACT

We evaluated the effects of Danggui-Chuanxiong (GX) herb pair with different proportions (1∶0, 3∶2, 1∶1, 2∶3, 0∶1) and preparation methods (water extract W, alcohol extract A, and water-alcohol extracts WA) on vasoactive substances and endothelial cell adhesion molecules in the serum of acute blood stasis in rats. An acute blood stasis model was co-replicated by ice water bath and subcutaneous injection of epinephrine hydrochloride in rats. The expressions of vasoactive substances (arachidonic acid metabolites, coagulation-fibrin system index) and adhesion molecules in the serum were detected by enzyme linked immunosorbent assay method; the Spearman method was used to analyze the correlation of those detection indicators; the partial least squares-discriminant analysis and multi-attribute comprehensive index method were used to comprehensively evaluate the total effect of GX herb pair samples with different proportions and preparation methods on vasoactive substances and adhesion molecules. The experimental scheme was approved by the Animal Experimental Ethics Committee of the First Affiliated Hospital of Henan University of Chinese Medicine. The results showed that GX 1∶1_WA had the strongest effect on the improvement of vasoactive substances and adhesion molecules in the serum of acute blood stasis in rats (the total effect value was 6.96). When extraction method was same, the overall effect of GX 1∶1 had better effect than that of other proportions; when the proportion of GX was same, the total effects of GX_WA and GX_A were better than GX_W. The combination of Danggui and Chuanxiong can significantly improve the expressions of vasoactive substances and adhesion molecules in the serum of blood stasis in rats. But the action strength of GX herb pairs was different when the proportions and preparations of GX herb pair were different. These findings provide a basis for clinical rational application of GX herb pair, and lay the foundation for in-depth research on GX herb pair for treatment of blood stasis related diseases.

ABSTRACT

In the present study,non-targeted metabolomics technique was used to screen potentially susceptibility biomarkers in patients with mild liver function abnormalities during long-term use of Chinese herbal compound. According to the inclusion and exclusion criteria,we collected 7 cases of patients with abnormal liver function during the period of complete taking Chinese herbal medicine( 60 days),and 18 cases of patients with normal liver function in re-examination from the reproductive medicine center in our hospital. Ultra performance liquid chromatography coupled with time-of-flight mass spectrometry( UPLC-Q-TOF/MS~E) technique combined with Progenesis QI software was used to analyze the differential biomarkers in serum of patients with wild liver function abnormalities and normal liver function. 11 potential biomarkers such as bilirubin,pantothenic acid,hippuric acid,sphingomyelin,palmitic acid,and oleic acid were tentatively identified. Metabolic disorders in patients with herbal-induced mild liver abnormality were mainly related to two pathways: pantothenic acid and coenzyme A biosynthesis and linoleic acid metabolism. It could provide a reference for the early warning of mild liver function abnormalities of patients that may be caused by long-term use of Chinese medicine compound in clinical application,and will lay a foundation for further understanding the endogenous substance changes in different levels of liver injury.

ABSTRACT

Aim: To evaluate the mouse model of hypertriglyceridemia (hTG) induced by schisandrin B (Sch B) using lipid metabolomics technology. Methods: Male ICR mice weighing 23 ~ 27 g were randomly divided into four groups: (1) mice fed with normal diet (ND group) (2) mice fed with ND and treated with Sch B(ND +Sch B group); (3) mice fed with high fat/fructose diet(HFFD group; fat, 10%; fructose, 10%; w/w), and (4) mice fed with HFFD and treated with Sch B (HFFD + Sch B group). Based on our previous research, Sch B at a single dose of 2 g · kg-1 was orally administered to the animals in the current study. Forty-eight hours later, serum samples were obtained from the orbital vein. Serum triglyceride (TG) and total cholesterol (TC) were analyzed by biochemical method. The metabolic fingerprint spectrum of serum in all groups were obtained and analyzed using ultra-performance liquid chromatography quadrupole-time-of-flight mass spectrometry (UPLC-Q/TOF-MS) method. The differences of metabolic spectra in every two groups were compared via the multivariate statistical methods. Results: Compared with ND group, three kinds (27 markers) of differential metabolites were identified in ND +Sch B group, including 18 TG, 7 phosphatidylcholine (PC), and 2 phosphatidylethano-lamine(PE). Compared with ND group, five kinds(27 markers) of differential metabolites were screened in HFFD group, including 6 sphingomyelin (SM), 13 PC, 2 cholesteryl ester(CE), 5 TG and 1 phosphati-dylinositol (PI). Compared with HFFD group, four kinds (25 markers) of differential metabolites were found in HFFD + Sch B group, involving 14 TG, 1 CE, 6 PC and 4 PE. Conclusion: These findings suggest that the animal model of hypertriglyceridemia established by Sch B involves the alteration of serum lipid metabolomics.
