SummaryWe investigated the effects of early rehabilitation therapy on prolonged mechanically ventilated patients after coronary artery bypass surgery (CABG).A total of 106 patients who underwent CABG between June 2012 and May 2015 were enrolled and randomly assigned into an early rehabilitation group (53 cases) and a control group (53 cases). The rehabilitation therapy consisted of 6 steps including head up, transferring from supination to sitting, sitting on the edge of bed, sitting in a chair, transferring from sitting to standing, and walking along a bed. The patients received rehabilitation therapy in the intensive care unit (ICU) after CABG in the early rehabilitation group. The control group patients received rehabilitation therapy after leaving the ICU.The results showed that the early rehabilitation therapy could significantly decrease the duration of mechanical ventilation (early rehabilitation group: 8.1 ± 3.3 days; control group: 13.9 ± 4.1 days, P < 0.01), hospital stay (early rehabilitation group: 22.0 ± 3.8 days; control group: 29.1 ± 4.6 days, P < 0.01), and ICU stay (early rehabilitation group: 11.7 ± 3.2 days; control group: 18.3 ± 4.2 days, P < 0.01) for patients requiring more than 72 hours prolonged mechanical ventilation. The results of Kaplan-Meier analysis showed that the proportions of patients remaining on mechanical ventilation in the early rehabilitation group were larger than that in the control group after 7 days of rehabilitation therapy (logrank test: P < 0.01).The results provide evidence for supporting the application of early rehabilitation therapy in patients requiring prolonged mechanical ventilation after CABG.

[4][5][6] Previous studies have shown that rehabilitation therapy could significantly reduce the length of hospitalization time, costs and complications, promote cardiac function recovery, and improve the quality of life in patients who underwent CABG. [7][8][9][10][11] Mechanical ventilation was routinely applied after CABG to reduce the power consumption of the respiratory system and the cardiac burden to improve postoperative cardiac recovery. [12][13][14] Due to a system of risk factors (such as the duration of surgery, anesthesia, clinical condition, mode of ventilator therapy, and method of weaning from mechanical ventilation), many patients should receive prolonged mechanical ventilation. [15][16][17] It was reported that the prolonged mechanical ventilation could prolong the hospital and intensive care unit (ICU) stay, 18) incre...
BACKGROUND: For patients in intensive care unit (ICU), mechanical ventilation is an effective treatment to survive from acute illness and improve survival rates. However, long periods of bed rest and restricted physical activity can result in side effects. This study aimed to investigate the feasibility of early rehabilitation therapy in patients with mechanical ventilation. METHODS:A randomized controlled trial was carried out. Sixty patients, with tracheal intubation or tracheostomy more than 48 hours and less than 72 hours, were admitted to the ICU of the Affi liated Hospital of Medical College, Qingdao University, from May 2010 to May 2012. These patients were randomly divided into a rehabilitation group and a control group. In the rehabilitation group, rehabilitation therapy was performed twice daily, and the training time and intensity were adjusted according to the condition of the patients. Early rehabilitation therapy included heading up actively, transferring from the supine position to sitting position, sitting at the edge of the bed, sitting in chair, transferring from sitting to standing, and ambulating bedside. The patient's body mass index, days to fi rst out of bed, duration of mechanical ventilation, length of ICU stay, APACHE II score, highest FiO 2 , lowest PaO 2 /FiO 2 and hospital mortality of patients were all compared between the rehabilitation group and the control group. The differences between the two groups were compared using Student's t test. RESULTS:There was no signifi cant difference in body mass index, APACHE II score, highest CONCLUSION: Early rehabilitation therapy was feasible and effective in improving the outcomes of patients with mechanical ventilation.
BackgroundMicroRNAs can act as both tumor suppressor genes and oncogenes and participate in cell proliferation, metastasis, and apoptosis. Low levels of miR‐577 are found in several cancers, for example, thyroid carcinoma, glioblastoma, and hepatocellular carcinoma. The aim of this study was to investigate the effect of miR‐577 on breast cancer (BC).MethodsThe relative level of miR‐577 in 120 BC tissues and cells was detected by real‐time PCR. MDA‐MB‐231 cells with upregulated miR‐577 and MCF‐7 cells with downregulated miR‐577 were established. Transwell invasion assays were used to examine the invasiveness of cells. Epithelial‐mesenchymal transition (EMT) markers were evaluated by immunofluorescence and Western blot. Targeted combinations of miR‐577 and Rab25 were analyzed by luciferase assays. Xenograft models were used to examine the effect of miR‐577 on BC metastasis.Results MiR‐577 expression was significantly suppressed in BC tissues. Tumor size, tumor stage, and lymphatic metastasis were attributed to miR‐577 expression. Moreover, miR‐577 overexpression strongly inhibited the invasiveness and EMT of BC cells in vitro. MiR‐577 directly regulated Rab25 in BC. Rab25 upregulation by miR‐577 decreased the levels of E‐cadherin and increased the levels of Vimentin. Notably, Rab25 knockdown inhibited BC invasion; however, an increase in Rab25 counteracted the invasive effect of miR‐577 in BC.ConclusionResults indicated that miR‐577 suppressed EMT by inhibiting Rab25 expression in BC. MiR‐577 and Rab25 are considered potential targets of BC treatment.
Introduction Fungal infection is increasingly common in critical illness with severe sepsis, but the influence of invasive fungal infection (IFI) on severe sepsis is not well understood. The aim of this study was to investigate the impact that IFI has on the outcomes of critically ill surgical patients with severe sepsis in China by means of matched cohort analysis; we also evaluated the epidemiologic characteristics of IFI in this population.
Introduction: It is necessary to evaluate fluid responsiveness before fluid resuscitation. We evaluated the value of inferior vena cava (IVC) area respiratory variation and the IVC diameter ratio (IVC DR) for predicting fluid responsiveness in mechanically ventilated patients. Methods: A prospective observational study was performed in the intensive care unit between December 2017 and March 2018. Mechanically ventilated patients were enrolled and received ultrasound monitoring. IVC diameter distensibility index from the subxiphoid area (IVC-sx DDI), IVC diameter distensibility index from the right midaxillary line (IVC-rm DDI), IVC area distensibility index (IVC ADI), and IVC DR in cross-section were calculated by ultrasound monitoring IVC parameters. The enrolled patients were classified as nonresponders group and responders group according to whether the cardiac output increased by >10% after passive leg raising. Results: Data from 67 mechanically ventilated patients were analyzed. 55.2% of patients had positive fluid responsiveness. The area of receiver operating characteristic curves evaluating the ability of the IVC-sx DDI, IVC-rm DDI, IVC ADI, and IVC DR to predict the fluid responsiveness were 0.702, 0.686, 0.749, and 0.829, respectively. IVC DR level of 1.43 was predictive of positive fluid responsiveness with 90.0% specificity and 67.6% sensitivity. IVC ADI level of 10.2% was predictive of positive fluid responsiveness with 40.0% specificity and 97.3% sensitivity. Conclusions: IVC ADI and its diameter ratio in cross-section had more value than IVC diameter distensibility index for predicting fluid responsiveness in mechanically ventilated patients.
