Common pathogenic bacteria-induced reprogramming of the host proteinogenic amino acids metabolism.

Apart from cancer, metabolic reprogramming is also prevalent in other diseases, such as bacterial infections. Bacterial infections can affect a variety of cells, tissues, organs, and bodies, leading to a series of clinical diseases. Common Pathogenic bacteria include Helicobacter pylori, Salmonella enterica, Mycobacterium tuberculosis, Staphylococcus aureus, and so on. Amino acids are important and essential nutrients in bacterial physiology and support not only their proliferation but also their evasion of host immune defenses. Many pathogenic bacteria or opportunistic pathogens infect the host and lead to significant changes in metabolites, especially the proteinogenic amino acids, to inhibit the host's immune mechanism to achieve its immune evasion and pathogenicity. Here, we review the regulation of host metabolism, while host cells are infected by some common pathogenic bacteria, and discuss how amino acids of metabolic reprogramming affect bacterial infections, revealing the potential adjunctive application of amino acids alongside antibiotics.

[Relationship between ultrasound imaging and traditional Chinese medicine syndrome in limb lymphedema].

OBJECTIVE: To study the correlation between traditional Chinese medicine (TCM) syndrome type and the ultrasound imaging changes in patients with limb lymphedema, and to provide evidence for TCM syndrome differentiation. METHODS: Syndrome typing was done and ultrasonography was performed in 107 patients with limb lymphedema. The thickenings of derma, hypodermis and deep-fascia were measured. The ultrasound echo intensity and the morphology of the hypodermis were classified into five degrees according to the ultrasonogram. The ultrasound indexes in the limb lymphedema patients with different syndromes were compared, and the relationship between TCM syndromes and the ultrasound indexes was analyzed. RESULTS: There were specific ultrasound image features in different TCM syndromes of limb lymphedema. The thickenings of derma, hypodermis and deep-fascia in the limb lymphedema patients with downward migration of damp-heat or phlegm stagnation and blood stasis were more significant than those in the patients with collateral obstruction due to cold-dampness (P<0.05, P<0.01). The thickenings of derma and hypodermis in the patients with phlegm stagnation and blood stasis were obviously more severe than those in the patients with downward migration of damp-heat (P<0.01). The maximum and minimum ultrasound echo intensities of hypodermis were in phlegm stagnation and blood stasis and downward migration of damp-heat respectively (P<0.05), and there was a significant difference in the hypodermal morphology among the three syndrome types (P<0.05). The most obvious structure disturbance was observed in the patients with phlegm stagnation and blood stasis syndrome. CONCLUSION: TCM syndrome type of limb lymphedema is related to ultrasound image changes. The imaging data can be regarded as new objective indexes for TCM syndrome differentiation, and it has an important value for diagnosis and treatment of limb lymphedema.
