ABSTRACT

The present study was aimed to investigate whether Gasdermin D (GSDMD)-mediated pyroptosis participated in lipopolysaccharide (LPS)-induced sepsis-associated acute kidney injury (AKI), and to explore the role of caspase-1 and caspase-11 pyroptosis pathways in this process. The mice were divided into four groups: wild type (WT), WT-LPS, GSDMD knockout (KO) and KO-LPS. The sepsis-associated AKI was induced by intraperitoneal injection of LPS (40 mg/kg). Blood samples were taken to determine the concentration of creatinine and urea nitrogen. The pathological changes of renal tissue were observed via HE staining. Western blot was used to investigate the expression of pyroptosis-associated proteins. The results showed that the concentrations of serum creatinine and urea nitrogen in the WT-LPS group were significantly increased, compared with those in the WT group (P < 0.01); whereas serum creatinine and urea nitrogen in the KO-LPS group were significantly decreased, compared with those in the WT-LPS group (P < 0.01). HE staining results showed that LPS-induced renal tubular dilatation was mitigated in GSDMD KO mice. Western blot results showed that LPS up-regulated the protein expression levels of interleukin-1β (IL-1β), GSDMD and GSDMD-N in WT mice. GSDMD KO significantly down-regulated the protein levels of IL-1β, caspase-11, pro-caspase-1, caspase-1(p22) induced by LPS. These results suggest that GSDMD-mediated pyroptosis is involved in LPS-induced sepsis-associated AKI. Caspase-1 and caspase-11 may be involved in GSDMD cleavage.

ABSTRACT

Neuropathy pain, or neuropathic pain (NP), which pathogenesis is complex and is lack of effective treatment, is one of common chronic pain in clinic. Studies of traditional Chinese medicine (TCM) in treating NP were increased in recent years. In the review, studies of treatments of TCM compound and monomer in NP during last decade were collected and analyzed to find out possible mechanisms, and some existing problems.

ABSTRACT

Fever and sweating are the most common clinical symptoms, which are important parts in the inquiry of traditional Chinese medicine (TCM). Just as Zhang Jingyue said, Firstly inquire for cold and heat and secondly in-quire for the sweating. It placed both symptoms as priorities in the collection of disease history. In the clinical prac-tice, febrile diseases refer to acute exogenous diseases infected by warm evil with the main symptom of fever. And fever is almost throughout the entire process of febrile diseases. It is also known as Han-Bing for the visible varia-tion of sweating in its entire disease process. It is important to identify the abnormality of sweating for the determina-tion of the severity febrile diseases and the level of body fluid shortage. Therefore, two main symptoms for the diag-nosis of febrile diseases are particularly prominent and important. The reasons of sweating and fever in febrile dis-eases have been explored so much but the relationship between them is less which is extremely essential to learn more about febrile diseases. So we are expected to explore this topic to make better use of theories of febrile dis-eases.
