Chinese herbal medicine for the treatment of diabetic nephropathy: From clinical evidence to potential mechanisms.

Ethnopharmacological Relevance: Diabetic nephropathy (DN) is a typical chronic microvascular complication of diabetes, characterized by proteinuria and a gradual decline in renal function. At present, there are limited clinical interventions aimed at preventing the progression of DN to end-stage renal disease (ESRD). However, Chinese herbal medicine presents a distinct therapeutic approach that can be effectively combined with conventional Western medicine treatments to safeguard renal function.

Chinese Herbal Medicines for Coronary Heart Disease: Clinical Evidence, Pharmacological Mechanisms, and the Interaction with Gut Microbiota.

Coronary heart disease (CHD) is a common type of cardiovascular disease (CVD) that has been on the rise in terms of both incidence and mortality worldwide, presenting a significant threat to human health. An increasing body of studies has shown that traditional Chinese medicine (TCM), particularly Chinese herbal medicines (CHMs), can serve as an effective adjunctive therapy to enhance the efficacy of Western drugs in treating CHD due to their multiple targets and multiple pathways. In this article, we critically review data available on the potential therapeutic strategies of CHMs in the intervention of CHD from three perspectives: clinical evidence, pharmacological mechanisms, and the interaction with gut microbiota.

Enterocytozoon bieneusi, Cryptosporidium spp. and Cyclospora cayetanensis are three important zoonotic pathogens which were a major cause of foodborne or waterborne intestinal diseases in humans and animals. However, very little data about occurrence and genotypes of the three parasites in Ningbo in the south wing of the Yangtze River Delta, China, which is important for a tourist city.

Discovery and Full Genome Characterization of SARS-CoV-2 in Stool Specimen from a Recovered Patient, China.

SARS-CoV-2 was found in a recovered patient's stool specimen by combining quantitative reverse transcription PCR (qRT-PCR) and genome sequencing. The patient was virus positive in stool specimens for at least an additional 15 days after he was recovered, whereas respiratory tract specimens were negative. The discovery of the complete genome of SARS-CoV-2 in the stool sample of the recovered patient demonstrates a cautionary warning that the potential mode of the virus transmission cannot be excluded through the fecal-oral route after viral clearance in the respiratory tract.

Development of a recombinase-aided amplification assay for rapid and sensitive detection of porcine circovirus 3.

Porcine circovirus type 3 (PCV3) is a novel member of the genus Circovirus, first detected in the United States in 2016, with subsequent reports in many countries. PCV3 infections have caused serious economic losses in the pig industry. Alternative rapid and sensitive assays for PCV3 detection are needed for clinical diagnosis, especially in laboratories not equipped with more sophisticated equipment.

[Prediction and Identification of Immunodominant Linear B Cell Epitopes in the Nucleocapsid Protein of SFTSV].

In order to identify immunodominant linear B cell epitopes in the nucleocapsid protein N of severe fever with thrombocytopenia syndrome virus(SFTSV),bioinformatics programs were used to analyze antigenicity, hydrophilicity and surface probability of the amino acid sequence and predict possible linear B cell epitopes. PyMOL software was used to analyze the distribution of linear B cell epitopes in nucleocapsid protein N based on its crystal structure. Corresponding peptides were synthesized and examined in peptide enzyme-linked immunosorbent assay(Peptide-ELISA)individually to check whether they reacted with sera from SFTSV-infected patients.
