ABSTRACT
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.
ABSTRACT
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.
ABSTRACT
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% (F = 65.87, P < 0.01), respectively. Transwell test showed that the number of migrating cells in 24 h control group, 2 ng/ml and 10 ng/ml TGF-beta groups were 127 ± 16, 230 ± 18, and 385 ±36 (F = 94.99, P < 0.01), respectively. The results of expression profiling showed that TGFβ regulates gene expression in hepatic progenitor cells, and differentially expressed genes participate in the PI3K-AKT signaling pathway. Signaling phospho antibody array and western blot showed that TGFβ regulated PI3K/AKT/mTOR/p70S6K signaling pathway in hepatic progenitor cells. Concurrently, immunofluorescence assay showed phosphorylation (p) 70s6k, p AKT1 and PI3K and F-actin co-localizations.@*Conclusion@#TGFβ can promote hepatic progenitor cell migration through PI3K/AKT/mTOR/p70S6K pathway, and p70S6K, pAKT1 and PI3K signaling molecules are involved in the regulation of morphology and migration of liver progenitor cells.
ABSTRACT
Objective To study the employment of noninvasive ventilation with nasopharyngeai airway in coma patients with cerebral stroke.Methods One hundred and fifty-five stroke patients treated with noninvasive ventilation admitted from May 2011 to May 2013 were studied.There were 88 male and 67 female,aged 30-95 years with mean age 73 years,The patients suffered from stroke with APACHE Ⅱ score 5-13 and Glasgow coma score 7-13.There were 78 cases in the nasopharyngeal airway group,and 77 cases in oropharyngeal airway group as control.SBP,DBP,HR,SpO2 and PCO2 were observed in the two groups at the time of beginning of noninvasive ventilation with neither airway (T0),and after placement of either airway and noninvasive ventilation for 10 min (T10),20min (T20),and 30 min (T30),respectively.The differences in rate of endotracheal intubation and the incidence of pulmonary infection were compared between the two groups.Results PaO2,SBP,PCO2 were improved after 30 minutes of noninvasive ventilation in the oropharyngeal airway group,and SBP DBP,HR decreased which were associated with improved respiration,less stress response,and then good blood circulation system.The better improvement of respiration was observed in nasopharyngeal airway group after 30 minutes of noninvasive ventilation.More improvements in PaO2,PCO2,SBP,DBP,HR were observed 30 minutes after noninvasive ventilation with nasopharyngeal airway compared with control group (P ＜ 0.05).The endotracheal intubation was used in 31 cases (40.3％) in the oropharyngeal airway group,and among them,19 cases (24.7％) suffered pulmonary infection.But there were 15 cases (19.2％) with endotracheal intubation in the nasopharyngeal airway group and 11 cases (14.1％) with pulmonary infection.The length of ICU stay,incidence of endotracheal intubation,and rate of pulmonary infection were lower in nasopharyngeal airway group (P ＜ 0.05).Conclusions The nasopharyngeal airway used in noninvasive ventilation can effectively ameliorate ventilation dysfunction in stroke patients,correct hypoxia and lessen accumulation of carbon dioxide,also reduce the pulmonary infection and the rate of endotracheal intubation.Nasopharyngeal airway used in noninvasive ventilation is a effective modality to solve upper airway obstruction and offer effective ventilation in stroke patients.
ABSTRACT
Objective To study the effects of high volume hemofiltration (HVHF) according to pulse-indicated continuous cardiac output (PiCCO) on patients with acute respiratory distress syndrome (ARDS).Methods A prospective randomly controlled trial was conducted.163 patients with ARDS admitted to Taizhou People's Hospital,Medical College,Nantong University,between February 2011 and January 2014,were enrolled.The patients were randomly divided into conventional therapy group (n＝ 50),HVHF group (n =55),and PiCCO + HVHF group (n＝58) by random number table.The patients in conventional therapy group received routine treatment including mechanical ventilation and drug treatment according to ARDS treatment guideline.The patients in the HVHF group received HVHF treatment of 18 hours per day on 1,3,5,7 days on the basis of conventional therapy.Patients in the PiCCO + HVHF group received HVHF treatment according to PiCCO.The indexes of lung function and PiCCO monitoring were recorded at intensive care unit (ICU) admission (before) and 4 days and 7 days after treatment.The serum levels of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) were determined by enzyme linked immunosorbent assay (ELISA),and the prognosis of patients was recorded.Results In three groups,oxygenation index (PaO2/FiO2),static lung compliance (Cs) were gradually increased,and respiratory rate (RR),lactic acid (Lac) were gradually decreased.The indicators in HVHF and PiCCO + HVHF groups were significantly improved compared with conventional therapy group.The indexes in PiCCO + HVHF group were significantly increased or decreased compared with those in HVHF group,and the statistical differences were found on the 7th day after treatment [PaO2/FiO2 (mmHg,1 mmHg=0.133 kPa):189.3 ± 36.8 vs.166.3 ± 36.1,Cs (mL/cmH2O):76.7 ± 18.9 vs.67.0 ± 18.2,RR (times/min):16.4 ±5.2 vs.19.2 ± 5.4,Lac (mmol/L):1.20 ±0.41 vs.1.41 ±0.43,all P＜0.01].In PiCCO +HVHF group,cardiac index (CI) was gradually increased,and extra vascular lung water index (EVLWI) and intra thoracic blood volume index (ITBVI) were gradually decreased.There were significant differences in the indexes 4 days and 7 days after treatment compared with those before treatment [CI (L·min-1·m-2):4.62 ± 1.13,4.83 ± 1.10 vs.4.01 ± 1.02,EVLWI (mL/kg):7.6 ± 2.7,6.5 ± 2.6 vs.12.4 ± 2.9,ITBVI (mL/m2):801.3 ± 120.9,785.4 ± 118.7 vs.980.1 ± 168.6,all P＜0.01].After treatment,the serum levels of TNF-α and IL-1β in three groups were gradually decreased.Compared with the conventional therapy group,the serum levels of TNF-α and IL-1β on 4 days and 7 days in the HVHF and PiCCO + HVHF groups were significantly decreased,and the statistical differences were found on 7 days [TNF-α (ng/L):68.35 ± 12.63,67.54 ± 12.90 vs.85.35 ± 13.70; IL-1β (ng/L):424.6 ± 142.9,412.2 ± 140.2 vs.895.2 ± 187.7,all P＜0.01].Compared with the HVHF group,the serum levels of TNF-α and IL-1β in the PiCCO + HVHF group were slightly decreased without statistical differences.Compared with the conventional therapy group,the number of organ failure,duration of mechanical ventilation,the length of stay in ICU and hospital mortality in HVHF group and PiCCO + HVHF group were lowered,and the statistical differences were found in PiCCO + HVHF group compared with HVHF group [number of organ failure:2.41 ± 0.79 vs.2.72 ± 0.80,duration of mechanical ventilation (days):4.8 ± 2.0 vs.5.7 ± 2.1,the length of stay in ICU (days):11.5 ± 3.4 vs.13.1 ± 3.6,hospital mortality:31.0％ (18/58) vs.41.8％ (23/55),all P＜0.05].Conclusions Levels of inflammatory factors in patients with ARDS could be reduced by HVHF.The oxygenation and compliance of lung can be improved,the number of organ failure can be lowered,the duration of mechanical ventilation and the length of stay in ICU can be shortened,and the hospital mortality could be declined by PiCCO guided HVHF.
ABSTRACT
Objective To detect the levels of high mobility group box 1 protein HMGB1),tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6),C-reactive protein (CRP) in order to explore the clinical significance of HMGB1 in patients with severely traumatic brain injury.Methods A total of 75 patients composed of 40 male and 35 female with severely traumatic brain injury were hospitalized from March 2011 through March 2012.The scores of Glasgow Coma Scale (GCS) were 5-8 within 12 hours after brain injury.Casualties with history of hypertension,diabetes,severe diseases of heart,liver and kidney,and with concurrent trauma of other parts of body were excluded.Another 50 healthy subjects were enrolled as controls.Serum samples were taken from both patients and controls at admission.The levels of HMGB1,TNF-α and IL-6 were measured by using enzyme-linked immunosorbent assay (ELISA).The level of CRP was measured by using automatic biochemistry analyzer.Comparisons of the levels of HMGB1,TNF-α,IL-6and CRP between casuahies and healthy controls were carried out.The correlations of HMGB1 with TNF-α,IL-6,CRP in patients with severe traumatic brain injury were analyzed.Thereafter,75 patients were divided into two groups post hoc:the death group and the survival group.On the 1st day,the 3rd day and the 7th day after trauma,serum HMGB1 was detected.The comparison of HMGB1 was made between death group and survival group by using t-test.Results Serum HMGB1 level in the traumatic patients was higher than that of healthy controls (P ＜ 0.01).Correlative analysis showed that there was a positive correlation between HMGB1 and TNF-α (r =0.365,P＜0.05),IL-6 (r=0.530,P＜0.05),CRP (r=0.661,P＜0.05) in patients with severe traumatic brain injury.Serum HMGB1 level in the death group was higher than the survival group (P ＜ 0.01).Conclusions Increased serum HMGB1 level was found after severe traumatic brain injury.There were positive correlations between HMGB1 and three inflammatory factors,TNF-α,IL-6and CRP.Serum HMGB1 should be used as reliable hiomarker to judge the prognosis of patients with severe traumatic brain injury.
