Objective:To explore the risk factors of acute kidney injury (AKI) in acute respiratory distress syndrome (ARDS) patients with mechanical ventilation.Methods:A retrospective analysis was conducted. ARDS patients with mechanical ventilation admitted to ICU of Taizhou People's Hospital from January 2019 to December 2019 were enrolled. Patients were divided into the AKI group and non-AKI group according to whether the patients had AKI. Clinical characteristics and laboratory indicators of the two groups were compared. Risk factors of incidence of AKI in ARDS patients were analyzed. The Kaplan-Meier survival curve was drawn to evaluate the survival rates of the two groups.Results:A total of 120 ARDS patients with mechanical ventilation were included, and 57 patients (47.5%) developed AKI. Procalcitonin, increased basal creatinine, decreased pH and impaired consciousness were independent risk factors for AKI in ARDS patients with mechanical ventilation. Fifty-seven of the 120 patients died with a mortality of 38.3%. The Kaplan-Meier survival curve showed that the survival rate of the AKI group was significantly lower than that of the non-AKI group ( P<0.001). Conclusions:The incidence and mortality of AKI is high in ARDS patients with mechanical ventilation. Procalcitonin, increased basal creatinine, decreased pH and impaired consciousness are independent risk factors for AKI in ARDS patients with mechanical ventilation.

Objective:To investigate the predictive value of serum proenkephalin A 119-159 (penKid) on incidence and the 28-day mortality in patients with sepsis-associated acute kidney injury (SA-AKI).Methods:This study was a single center, observational cohort study. Sepsis/septic shock patients admitted to Department of Critical Care Medicine of Taizhou People's Hospital Affiliated to Nanjing Medical University from September 2021 to September 2022 were selected and divided into the SA-AKI group and the non-SA-AKI group according to whether acute kidney injury (AKI) occurred within 28 days. Patients in the SA-AKI group were subdivided into the death group and the survival group according to whether death occurred within 28 days. Baseline data and laboratory indicators such as penKid concentration were compared among different groups. COX regression analysis was used to explore the risk factors of death within 28 days in the SA-AKI patients, And Kaplan-Meier curve was used to analyze patient prognosis.Result:A total of 161 patients were included in this study, of whom 66 (41.0%) developed AKI. The baseline penKid concentration in the SA-AKI group was significantly higher than that in the non-SA-AKI group [(2.99 ± 0.68) μg/L vs. (1.86±0.75) μg/L, P<0.05]. Multivariate COX regression analysis showed that the baseline penKid ( HR=5.608, 95% CI: 3.507-8.967, P<0.001) and lactate (LA) ( HR=1.089, 95% CI: 1.003-1.183, P=0.043) were independent risk factors for AKI in sepsis/septic shock patients. Of the 66 SA-AKI patients, 27 (40.9%) died within 28 days, and the baseline penKid concentration in the death group was significantly higher than that in the survival group [ (3.55 ± 0.54) μg/L vs. (2.60±0.47) μg/L, P<0.05]. COX regression analysis showed that penKid ( HR=5.892, 95% CI: 2.457-14.132, P<0.001) was an independent risk factor for mortality in SA-AKI patients. Kaplan-Meier curve showed that the 28-day mortality of patients with baseline penKid ≥ 3.24 μg/L was significantly higher than that of patients with baseline penKid <3.24 μg/L ( P<0.001). Conclusions:In sepsis/septic shock patients, the penKid concentration measured on the first day in the SA-AKI group is significantly higher than that in the non-SA-AKI group. In SA-AKI patients, the penKid concentration measured in patients who survived within 28 days is significantly lower than that in the death group. PenKid is an independent risk factor for the occurrence and death of SA-AKI.

Objective:To explore the effect of pectin on improving intestinal barrier injury in elderly stroke patients.Methods:A total of 60 elderly stroke patients who received enteral nutrition in Department of Critical Care Medicine of Taizhou People's Hospital from November 2020 to October 2021 were included. The control group included 30 cases, using conventional enteral nutrition solution. The other 30 cases were in the study group, and pectin was added on the basis of routine enteral nutrition solution. The levels of serum diamine oxidase (DAO) and D-lactic acid (D-LA) were measured on the first and 7th days of enteral nutrition to evaluate the intestinal barrier function of elderly stroke patients. The levels of interleukin-6 (IL-6), procalcitonin (PCT) and high-sensitivity C-reactive protein (CRP) were measured to evaluate the inflammatory response level of elderly stroke patients. The clinical prognosis of the two groups was compared.Results:Compared with the control group, the values of DAO [(4.05±1.56)ng/mL] and D-LA [(6.11±2.20) μmol/L] in the study group were significantly lower than those in the control group on the 7th day (all P < 0.05). Also the levels of IL-6 [(15.43±12.53) ng/mL], PCT [(0.82±0.98) ng/mL] and CRP [(6.94±6.60) mg/L] in the study group were lower than those in the control group, and the difference between the two groups was statistically significant (all P < 0.05). Compared with the control group, the length of ICU stay and total length of hospital stay in the study group were shorter than those in the control group ( P<0.05), but there was no significant difference in the incidence of stroke-related pneumonia (16.7% vs. 30.0%) and 30-day mortality (16.7% vs. 20.0%) between the two groups ( P>0.05). Conclusions:The enteral nutrition with pectin supplementation can improve intestinal barrier function and reduce inflammatory response in elderly stroke patients.

Objective:
To investigate the effect and mechanism of transforming growth factor β (TGFβ) on the migration ability of hepatic progenitor cells in vitro.
Methods:
Primary hepatic progenitor cells of male wild-type C57BL/6J mice were isolated by two-step perfusion method and stimulated with different concentrations of TGFβ .The morphological changes were observed under phase -contrast microscopy. The effects of TGFβ on migration ability of hepatic progenitor cells were evaluated by scratch test and transwell method. Expression profiling and signaling phospho antibody array detected the signaling pathways involved in the regulation of TGFβ on hepatic progenitor cells. Protein level of PI3K/AKT/mTOR/p70S6K signaling pathway and the localization of each signaling molecules in hepatic progenitor cells were detected. Data comparison between the two groups was performed by independent sample t-test. One-way ANOVA was used for data comparison between multiple groups.
Results:
TGFβ made the liver progenitor cells from oval to long spindle type. Scratch test showed that the scratch healing rates of 24 h control group, and 2 ng/ml and 10 ng/ml TGF-beta groups were 36.48% ± 4.37%, 57.35% ± 4.60%, and 73.14% ± 5.02% (
