ABSTRACT
Objective@#To explore the clinical features and risk factors of hepatic injury due to immune checkpoint inhibitors (CPI) therapy in malignant tumor.@*Methods@#Data of 112 patients (64 men and 48 women) who received CPI between January 2016 and March 2019 in Chinese Academy of Medical Sciences and Peking Union Medical College Shenzhen Hospital, and Huazhong University of Science and Techology Union Shenzhen Hospital were retrospectively collected. The median age of these patients was 60 years.@*Results@#Hepatic adverse events were observed in 30 patients out of 112 patients (26.8%). Among them, the incidence of grade 3-5 hepatic adverse events were 7.14% (8/112). The median time of hepatic adverse event occurrence was 3 weeks (2-30) after undergoing therapy. The results of univariate and multivariate analyses showed that liver cancer was attributed to the CPI induced hepatitis (P<0.05). Patients with severe hepatic injury got almost complete resolution after receiving methlprednisolone for 4 to 6 weeks.@*Conclusion@#Live cancer is the risk factor of CPI-related hepatic adverse events.
ABSTRACT
Objective@#To investigate the influence of serum creatinine (sCr) at different time-points on prognosis of critically ill patients with acute kidney injury (AKI).@*Methods@#This study was retrospectively analyzed the clinical data of critical patients with AKI who admitted to the mixed ICU of Xiaolan Hospital of Southern Medical University during March 2015 and January 2016. According to the clinical prognosis, the patients were divided into the renal replacement therapy (RRT) group and non-renal replacement therapy (non-RRT) group, 28-day renal loss group and renal recover group, hospital death group and survival group. Serum Cr at different time-points and clinical data were collected. The receiver operating characteristic (ROC) curve and the area under curve (AUC) were used to evaluate the capability of sCr at different time-points in predicting clinical prognosis.@*Results@#During the study, 85 AKI patients were enrolled. The in-hospital mortality was 20%, RRT rate was 15.3%, and renal lose at 28 days after ICU admission was 31.8%. The levels of sCr out of ICU (o-sCr) and the peak of sCr were significantly higher in the RRT group than the non-RRT group (P<0.01). The o-sCr and p-sCr predicted RRT during the hospital stay with a higher AUC value (0.806 vs 0.833) than b-sCr and a-sCr. The levels of b-sCr, a-sCr, o-sCr, and p-sCr were all significantly higher in the28-day renal loss group than the kidney recover group (P<0.01). The levels of o-sCr and p-sCr were significantly higher in the hospital death group than the survival group (P<0.05). The o-sCr predicted renal lose at 28 days and hospital death with the highest AUC value of 0.850 and 0.797, respectively.@*Conclusions@#It cannot be ignored to monitor dynamically the level of sCr at different time-points in critical patients with AKI, which can predict the clinical prognosis such as hospital death, RRT and renal lose at 28 days after ICU admission.

ABSTRACT
Objective To investigate the clinical value of serum cystatin C (sCysC) and APACHE Ⅱ score in predicting diagosis and prognosis of acute kidney injury(AKI) in patients with sepsis. Methods In this study, we prospectively enrolled 138 adult patients with sepsis who had been admitted to the mixed ICU of Xiaolan Hospital of Southern Medical University during March 2015 to January 2016. According to the Kidney Disease Improving Global Outcomes (KDIGO) criterion, the patients were divided into non-AKI group and AKI group (including mild AKI and severe AKI). The receiver operating characteristic(ROC) curve and the area under curve(AUC) were used to evaluate these indexes' capability of detecting septic AKI and its prognosis. Results In this study,72 patients (52.2％) developed AKI. The levels of sCysC and APACHE Ⅱ score were significantly higher in AKI than in non-AKI (P<0.05). In total, 33 patients (23.9％) developed severe AKI. The levels of sCysC and APACHE Ⅱscore were significantly higher in severe AKI than in non-AKI and mild AKI (P<0.05) . Combination of sCysC and APACHE Ⅱ score predicted AKI and severe AKI after ICU admission with a higherAUC value (0.880&0.930) than each biomarker alone. In this cohort, in-hospital mortality was 19.6％and renal replacement therapy rate was 9.4％,which were strikingly higher in AKI group than non AKI group (P<0.05). Conclusions sCysC is a novel indexes for predicting AKI and its prognosis in patients with sepsis. Combinating with APACHE Ⅱ score can further improve its predictive performance of AKI detection and short-term prognosis.
ABSTRACT
Objective:To examine the oncogenic mutations involved in melanoma in Southern China and to provide a theoretical basis for the development of melanoma molecular targeted therapy strategy. Methods:The Sequenom platform (OncoCarta Panel v1.0 and MassARRAY System) was used to determine the prevalence of oncogene mutations in 28 acral melanoma samples, 28 mucosal mel-anoma samples, and 30 non-chronic sun-induced-damage (no-CSD) melanoma samples from Southern China. Results:At least one mu-tation was detected in 33 of the 86 melanomas (38.4%) with mutations observed in BRAF (16.3%), NRAS (10.5%), KIT (5.8%), EGFR (4.7%), HRAS (2.3%), KRAS (2.3%), MET (2.3%), and PIK3CA (1.2%). In BRAF, the age of patients with mutations was significantly lower than those without BRAF mutation (45.7±15.3 vs. 55.9±12.7, P=0.01). Patients with mutations in NRAS were more likely to have ulceration compared with patients without NRAS mutations (88.9%vs. 48.1%, P=0.049). Conclusions:This study represents a compre-hensive and concurrent analysis of the major recurrent oncogenic mutations involved in melanoma cases from Southern China areas. The data have implications for both clinical trial designs and therapeutic strategies.
ABSTRACT
The present study attempted to observe the protective effects of tungsten (W) on hepatic injury induced by endotoxic (ET) shock in rats and to study its mechanisms. 28 male Wistar rats were randomly divided into 3 groups: (1) ET group (n=11): a bolus injection of disintegrated E. Coli (5?4?10~(10) organisms/kg); (2) ET+W group: (n=11) an equivalent E. Coli was given after being pretreated with sodium tungstate rich food and water for 3-4 weeks; (3) Control group (n=6): NS. The results showed that pretreatment with W significantly attenuated the decrease of BP, total count of WBC and% of PMN, and increased the survival rate. In ET+W group, Plasma level of malondialdehydc decreased; activity of XO in hepatic tissue also decreased; the ratio of W/Mo increased, the serum GPT level decreased (P
