[Retrospective cross-sectional survey of clinical characteristics and syndrome elements distribution at different stages of coronary heart disease].

The clinical data of coronary heart disease(CHD) patients treated in the First Affiliated Hospital of Guangzhou University of Chinese Medicine and Shenzhen Hospital of Integrated Traditional Chinese and Western Medicine from January 2022 to March 2023 were retrospectively collected. This study involved the descriptive analysis of demographic characteristics, clinical symptoms, and tongue and pulse features. The χ~2 test was conducted to analyze the distribution of syndrome elements and their combinations at diffe-rent stages of CHD, so as to reveal the clinical characteristics and syndrome patterns at various pathological stages of CHD.

Characterization of a Phosphatidylserine Synthase of Vibrio parahaemolyticus.

Phosphatidylserine synthase (Pss) is involved in the metabolic pathway in phospholipid synthesis in different organisms. In this study, Pss expression in Vibrio parahaemolyticus was verified through liquid chromatography tandem-mass spectrometry. To analyze the characteristics of Pss, the recombinant Pss was overexpressed and purified from Escherichia coli.

Molecular and functional evidence of phosphatidylserine synthase in Vibrio parahaemolyticus.

Phosphatidylserine synthase (Pss) catalyzes phosphatidylserine synthesis, which is critical to synthesizing the component of cell membrane. However, few putative pss genes of bacteria have been studied. In this study, it was found that Vibrio parahaemolyticus, a common foodborne pathogen that causes human gastroenteritis, has a type I Pss with two HKD motifs and is a phospholipase D superfamily member.
