ABSTRACT
Nowadays potential preclinical drugs for the treatment of nonalcoholic steatohepatitis (NASH) have failed to achieve expected therapeutic efficacy because the pathogenic mechanisms are underestimated. Inactive rhomboid protein 2 (IRHOM2), a promising target for treatment of inflammation-related diseases, contributes to deregulated hepatocyte metabolism-associated nonalcoholic steatohepatitis (NASH) progression. However, the molecular mechanism underlying Irhom2 regulation is still not completely understood. In this work, we identify the ubiquitin-specific protease 13 (USP13) as a critical and novel endogenous blocker of IRHOM2, and we also indicate that USP13 is an IRHOM2-interacting protein that catalyzes deubiquitination of Irhom2 in hepatocytes. Hepatocyte-specific loss of the Usp13 disrupts liver metabolic homeostasis, followed by glycometabolic disorder, lipid deposition, increased inflammation, and markedly promotes NASH development. Conversely, transgenic mice with Usp13 overexpression, lentivirus (LV)- or adeno-associated virus (AAV)-driven Usp13 gene therapeutics mitigates NASH in 3 models of rodent. Mechanistically, in response to metabolic stresses, USP13 directly interacts with IRHOM2 and removes its K63-linked ubiquitination induced by ubiquitin-conjugating enzyme E2N (UBC13), a ubiquitin E2 conjugating enzyme, and thus prevents its activation of downstream cascade pathway. USP13 is a potential treatment target for NASH therapy by targeting the Irhom2 signaling pathway.
ABSTRACT
Objective It is necessary for nursing staff members to assign priorities in health education to hospitalized patients to ensure curative effect .The purose of the study was to explore the effect of process management application in health education path -way to patients with rheumatoid arthritis ( RA) . Methods A total of 70 patients with rheumatoid arthritis were randomly divided into observation group and control group , 35 patients in each group .Traditional health education was done in control group , while health education pathway was performed in observation in observation group according to process management .A study of patients′satisfaction with hospitalization , compliance of medication and knowledge of health education was undertaken . Results Observation group had priority to control group in satisfaction with hospitalization and medication compliance (77.1% vs 42.9%,P 0.05). Conclusion Compared with traditional health educa-tion, the process management application of RA health education pathway helps to improve patients ′health konwledge and medical compliance , which is an effective adjuvant treatment .
ABSTRACT
Objective To evaluate the impact of masticatory function on malnutrition and gastrointestinal symptoms in senile patients.Methods Dental status and denture quality in 120 senile patients were investigated with questionnaires,and thecorrelation of masticatory ability with nutritional status and gastrointestinal symptoms were evaluated.Results The nutritional status of elderly patients was correlated with the condition of the denture,but not correlated with the number of denture and chewing ability.Gastrointestinal disconffort had correlation with masticatory function,chewing problems,difficulty in chewing and food limit,but chewing function was highly correlated with taking gastrointestinal drugs.Conclusions The chewing ability and nutritional status is not relevant,but since elderly patients with weakened chewing ability avoid certain foods,thus gastrointestinal discomfort and symptoms of gastrointestinal disorders such as medication increased.
ABSTRACT
Objective:To assess incidence of malnutrition and malnutrition risk of six department patients.Methods:The information of 1 200 patients were collected,200 in each of 6 departments in our hospital.Nutrition status was assessed according to Nutrition Risk Screening(NRS)published by ESPEN in 2001.Results:The incidence of malnutrition and malnutrition risk varied from 7.5% to 59% and 36% to 72% respectively in different department.Conclusion:The incidence of malnutrition is closely related to the kind and severity of the disease.It is nessissary to assess the nutrition status of high risk patients in time.NRS can be used simply and fastly in most inhospital patients.
