Résumé
In recent years, immunotherapy with immune checkpoint as the target has made revolutionary breakthroughs in the treatment of a variety of advanced solid tumors. Notwithstanding the impressive long-term therapeutic benefits, their efficacy is limited to a small subset of cancer patients. Some patients experienced drug resistance and immune-related adverse events (irAEs). Immune checkpoint inhibitors (ICIs) primarily include antibodies targeting CTLA-4 and antibodies targeting PD-1 and its ligands. Thus, it is of utmost importance to screen potential biomarkers in populations that may benefit from immunotherapy, to maximize therapeutic benefits. This review summarizes the mechanism of ICIs and its related efficacy biomarker, to better guide the application of immunotherapy in clinical practice.
Résumé
Objective To evaluate the therapeutic effect of extract of ginkgo biloba (EGB) on hepatic damage of neonatal rats with hypoxic ischemic brain damage(HIBD). Methods Sixty six Sprague Dawley(SD) neonatal rats were divided into four groups: groupⅠincluded neonatal rats with hypoxic ischemic hepatic damage after HIBD group I, ( n=30 ), groupⅡ( n=24 ) was those with EGB-treated, groupⅢ ( n=6 ) was those with saline-treated and groupⅣ ( n=6 ) which had sham operation. ICAM-1 of liver was detected at different times in the first two groups after HIBD and the rest groups by immunohistochemical ABC method. Simultaneously HE was employed to display neutrophil infiltrations in hepatic tissue and pathologic characteristics of liver cells. Results The expression of ICAM-1 increased at 24 h [(52.5?17.0)%] with resupply oxygen, peaked at 48 h [ (76.5 ?11.9)%] ( H=23.9,P
Résumé
Objective To study the morbidity of Toxoplasma (TOX) and Cytomegalovirus (CMV) infection in in patient infants and their clinical character Methods The serum CMV IgG/IgM and TOX IgG/IgM ware measured by enzyme linked immunosorbant assay (ELISA) Results The positive rate of CMV IgG, CMV IgM, TOX IgG and TOX IgM were 86.7%, 5.2%,13.9% and 0.4% respectively in in patient infants. The main clinical manifestication of neonatal TOX and CMV infection were premature, small for gestational age, neonatal pneumonia, sepsis, encephalopathy, hepatitis syndrome Conclusion TOX and CMV infection were widely noticed in in patient infants, and their potential damage should be greatly considered in our clinical practice.
Résumé
Objectives: To compare the effect of different fat emulsions on the blood lipid and liver function in neonates with hepatic dysfunction. Methods:40 babies with hyperbilirubinemia(≥51.3 mmol/L) were randomly divided into two groups ,receiving the fat emulsion of 20% Intralipid (LCT group) or 20% Lipofundin (MCT/LCT group) at the dose of 2.0 g/(kg?d) for 7 days. Blood lipid 〔total cholesterol(TC), triglyceride(TG)〕 and the serum biochemical indexes relative to liver function were measured before and after the period of 7 days. Results:The levels of TC did not change remarkably in two groups. There was significant difference in the levels of TG between the two groups after the study period (1.87?0.3 mmol/L in LCT group and 1.15?0.27 mmol/L in MCT/LCT group, t =7.833, P
