Objective To evaluate the effect of transcutaneous neuromuscular electrical stimulation on prevention of intensive care unit-acquired weakness (ICU-AW) in chronic obstructive pulmonary disease (COPD) patients with mechanical ventilation. Methods A prospective randomized controlled study was conducted. Sixty COPD patients aged 18-85 years old who were accepted mechanical ventilation therapy admitted to general intensive care unit (ICU) of the First Affiliated Hospital of Hunan University of Medicine from October 2017 to October 2018 were enrolled. Patients were divided into control group (n = 30) and intervention group (n = 30) by random number table method. All patients were accepted routine treatment, and on this basis, the intervention group was applied transcutaneous neuromuscular electrical stimulation on the extremities (twice a day, 30 minutes each time) after 24 hours of admission until ICU discharge. The Medical Research Council muscle strength score (MRC-Score), grip strength, incidence of ICU-AW on the 7th day after admission and on the day of ICU discharge; modified Barthel index score on the day of ICU discharge; and duration of mechanical ventilation, the length of ICU stay, and the length of hospital stay were compared between the two groups. Results Twenty-nine and 27 patients in the control group and the intervention group respectively finally completed the study in dividually. There was no significant difference in gender, age, Barthel index score before 2 weeks of ICU admission, body mass index or acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) in ICU between the two groups. There was no significant difference in the MRC-Score, grip strength or incidence of ICU-AW on the 7th day after ICU admission between the two groups. Compared to the control group, the MRC-Score, grip strength and Barthel index score in the intervention group were significantly increased [MRC-Score: 55.97±8.43 vs. 46.32±7.36, grip strength (kg): 33.46±11.62 vs. 27.42±9.64, Barthel index score:46.04±5.46 vs. 42.13±3.32, all P < 0.05], the incidence rate of ICU-AW was significantly decreased [7.4% (2/27) vs. 31.0% (9/29), P < 0.05], and duration of mechanical ventilation, the length of ICU stay, the length of hospital stay were significantly shortened [duration of mechanical ventilation (days): 5.12±2.01 vs. 7.24±4.35, the length of ICU stay (days): 8.34±2.36 vs. 10.45±2.62, the length of hospital stay (days): 13.21±2.21 vs. 15.38±3.67, all P < 0.05]. Conclusion Transcutaneous neuromuscular electrical stimulation can effectively improve the muscle strength of COPD patients with mechanical ventilation and reduce the incidence of ICU-AW.

OBJECTIVETo explore the safety and efficacy of pegylated recombinant human granulocyte colony-stimulating factor (PEG-rhG-CSF) in preventing chemotherapy-induced neutropenia in patients with breast cancer and non-small cell lung cancer (NSCLC), and to provide the basis for clinical application.
METHODSAccording to the principle of open-label, randomized, parallel-group controlled clinical trial, all patients were randomized by 1∶1∶1 into three groups to receive PEG-rhG-CSF 100 μg/kg, PEG-rhG-CSF 6 mg, or rhG-CSF 5 μg/kg, respectively. The patients with breast cancer received two chemotherapy cycles, and the NSCLC patients received 1-2 cycles of chemotherapy according to their condition. All patients were treated with the combination chemotherapy of TAC (docetaxel+ epirubicin+ cyclophosphamide) or TA (docetaxel+ epirubicin), or the chemotherapy of docetaxel combined with carboplatin, with a 21 day cycle.
RESULTSThe duration of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg and PEG-rhG-CSF 6 mg groups were similar with that in the rhG-CSF 5 μg/kg group (P>0.05 for all). The incidence rate of grade 3-4 neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group, and G-CSF 5 μg/kg group were 69.7%, 68.4%, and 69.5%, respectively, with a non-significant difference among the three groups (P=0.963). The incidence rate of febrile neutropenia in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg/kg group were 6.1%, 6.4%, and 5.5%, respectively, showing no significant difference among them (P=0.935). The incidence rate of adverse events in the PEG-rhG-CSF 100 μg/kg group, PEG-rhG-CSF 6 mg group and G-CSF 5 μg / kg group were 6.7%, 4.1%, and 5.5%, respectively, showing a non-significant difference among them (P=0.581).
CONCLUSIONSIn patients with breast cancer and non-small cell lung cancer (NSCLC) undergoing TAC/TA chemotherapy, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF at 48 hours after chemotherapy show definite therapeutic effect with a low incidence of adverse events and mild adverse reactions. Compared with the continuous daily injection of rhG-CSF 5 μg/kg/d, a single 100 μg/kg injection or a single fixed 6 mg dose of PEG-rhG-CSF has similar effect and is more advantageous in preventing chemotherapy-induced neutropenia.
