RESUMEN
Apical sodium-dependent bile acid transporter （ASBT） is a key transporter responsible for intestinal reabsorption of bile acid and plays an important role in maintaining bile acid and cholesterol homeostasis， and its expression is regulated by various factors including transcription factors， nuclear receptors， and intestinal microflora. The abnormal expression and function of ASBT can lead to disorders in the metabolism of bile acid and cholesterol， causing a variety of hepatobiliary diseases. At present， ASBT has attracted wide attention as a therapeutic target. This article elaborates on the biological characteristics and expression regulation mechanism of ASBT and reviews the role of ASBT in hepatobiliary diseases， in order to provide a new direction for the treatment of related diseases.
RESUMEN
Children with infantile cholestatic liver disease are often accompanied by malnutrition, which in turn can affect its progression and prognosis. There are many factors causing malnutrition and various methods for malnutrition assessment, but there is still a lack of uniform standard for nutritional assessment in patients with liver diseases, and a variety of indicators and methods are required for comprehensive analysis and assessment. This article analyzes the common causes of malnutrition in children with cholestatic liver disease, introduces the different methods for nutritional assessment, including anthropometric measurements, laboratory examination, and nutritional assessment tools, and elaborates on nutritional intervention treatment, so as to improve the understanding of nutritional problems in children with cholestatic liver disease. Early identification and rational interventions can help to improve the quality of life and prognosis of children.
RESUMEN
Objective To study the influence of intraoperative use of saline and balanced salt solution on postoperative nerve function recovery in patients with brain trauma.Methods Totally 120 patients were randomly divided into the saline group and the balanced salt solu-tion group,and the postoperative nerve function recovery of the two groups were observed.Results The level of pH and HCO3 -24 hours af-ter operation in the saline group were lower than those in the balanced salt solution group (P <0.05),while the level of Cl - in the saline group was higer than that in the balanced salt solution group (P <0.05).The intracranial pressure and preoperative Glasgow coma score (GCS)of the two groups had no statistical significance (P =0.94).And the Glasgow coma score at 336 hours and 672 hours after opreation of the two groups were of statistical significance (P =0.00,P =0.03).The mortality of the saline group and the balanced solution group 28days after surgery were 15% and 10% respectively,and there was no significant difference between the two groups (P =0.58).Conclusion Saline resuscitation during surgery would lead to hyperchloremic acidosis as well as worse nerve function.However,the perfusion of balanced salt solution during the operation is more favorable to the recovery of neurological function.
RESUMEN
Objective To find out nosocomial infection of elde rly patients in our nosocomial and to provide theoretical evidence for preventing nosocomial infection of elderly patients. Methods 601 elderly p ati ents of internal medicine in our hospital were investigated with prospective and retrospective methods from January 1996 to December 1998. Results Nosocomial infectious rate in this age was 8.32%, and it was higher than mean nosocomial infectious rate in our nosocomial during the last three years( 1.48%). Infectious sites was mostly the lower respiratory tract, and it's infe ctious r ate was 52%. Basic diseases such as endocrine system， circulatory system， dige stive system， genitourinary system， respiratory system diseases were higher in nosocomial infection. Opportunitive pathogens were the main cause of the nosocomial infectious pathogens, and fungi took 85% of the opportunitive pa thogens. Conclusions Nosocomial infectious factors are mainly that immune function is lower in the aged and antibiotic is used generally.
