ABSTRACT
Objective To study the effect of mean arterial pressure (MAP) level on acute kidney injury (AKI) in patients with septic shock, and to determine the best resuscitation target MAP to prevent the occurrence or progression of sepsis- associated AKI.Methods The study subjects included 168 adult patients with septic shock (age≥65 years) who were admitted to the Department of Intensive Care Unit (ICU) of the First Hospital of Jilin University from January 2016 to January 2019. The clinical data of all enrolled patients were retrospectively analyzed. The baseline data were compared between the AKI group (n=111) and non-AKI group (n=57). Multivariate logistic regression analysis was used to determine the risk factors of AKI in patients with septic shock.Results ① The first, second, third, and forth quartile ofΔMAP (pre-resuscitation MAP minus post-resuscitation MAP) were -24.3-3.9 mmHg, 4.0-12.3 mmHg, 12.4-19.8 mmHg, and 19.9-43.5 mmHg, respectively. The second to fourth quartile interval wasΔMAP≥4 mmHg.② There were no significant differences in age, body mass index, sex, pre-resuscitation MAP, MAP at first hour, SOFA score, positive culture ratio, negative culture ratio, hypertension, peripheral vascular disease, cerebrovascular accident, chronic obstructive pulmonary disease, gastrointestinal ulcer, liver cirrhosis, and tumor between the two groups (P>0.05). There were significant differences in post-resuscitation MAP (P=0.01), APACHEⅡ score (P=0.02), diabetes mellitus (P=0.01), fluid balance (P=0.01), andΔMAP from the second to fourth quartile (P=0.03) between the two groups.③ΔMAP≥4 mmHg (OR=0.26, 95％CI: 0.12-0.57,P=0.01), diabetes (OR=6.03, 95％CI: 1.35-44.16,P=0.04), and high APACHEⅡ score (OR=0.96, 95％CI: 0.84-0.97,P=0.02) were closely related to the increased incidence of AKI in patients with septic shock. Post-resuscitation MAP and fluid balance had no significant effect on the incidence of AKI in patients with septic shock.Conclusions ΔMAP≥4 mmHg, APACHEⅡ score and diabetes were independent risk factors for the incidence of AKI in patients with septic shock. The incidence of AKI in septic shock patients with post-resuscitation MAP 4 mmHg or more lower than pre-resuscitation MAP is significantly increased.

ABSTRACT
Objective:we aim to determine the relationship between Cell sarcoma (c-Src) expression in patients with EOC and the disease phenotype.Methods:c-Src expression was evaluated using Western blotting analysis in 21 ovarian carcinomas and 4 normal ovarian tissues.Immunohistochemistry was used to evaluate c-Src expression in 134 ovarian carcinomas and 26 normal ovarian tissues.The association between c-Src expression and clinically pathologic characteristics were also assessed in these patients.Results:Our results indicated elevated c-Src protein in EOCs compared with that in normal tissues.The overexpression of c-Src was significantly associated with aggressive features,such as advanced disease stage,poor histological grade,lymph node metastasis,and tumor recurrence (P＜0.05).In addition,the overexpression ofc-Src is significantly associated with EOCs' prognosis.Conclusion:c-Src overexpression was significantly associated with the malignant biological behavior of tumor,suggesting c-Src as a potential preventive target in these patients.
