Objective We aimed to investigate simulated in-hospital cardiopulmonary resuscitation (CPR) quality and rescuer fatigue of external chest compression-only CPR by a manual leverage device(LDCPR). Methods All 12 volunteers (medical staffs: male 6 and female 6) were randomized to standard CPR by hand(STCPR)group (n=6)or LDCPR group(n=6). At STCPR group, continuous external chest compression-only was performed for 6 minutes to simulate in hospital cardiopulmonary resuscitation on a manikin; at LDCPR group, compression-only was performed for 6 minutes by a leverage device on a manikin. We measured blood pressure of the volunteers before and after performing each CPR technique, volunteers self-report fatigue scale and continuously monitored heart rate (HR) of the volunteers during each CPR technique by smart ring. CPR quality measures included chest compression rate and depth. Results During continuous external chest compression-only CPR, compressor's heart rate and fatigue scale were rising continuously, and percent of compress depth >5 cm were declining, too.Compressor's heart rate and fatigue scale were higher in the STCPR group than in the LDCPR group (P<0.05) during the fourth to sixth minutes CPR (P<0.05). Percent of compress depth > 5 cm was higher in the LDCPR group than in the STCPR group (P<0.05) during the fourth to sixth minutes of CPR (P<0.05).Compress rate had not differed between the 2 groups during CPR. Conclusion In the manikin study, manual leverage external chest compress device may reduce fatigue scale and improve long term compression quality during in-hospital cardiopulmonary resuscitation.

Objective To investigate the effects of mirror visual feedback (MVF) and modified constraint-induced movement therapy (mCIMT) on upper extremity function in post-stroke hemiplegics. Methods 117 patients with hemiplegia post-stroke were collected prospectively from December 2013 to October 2016, and randomly divided into the following four groups: group A (n=30), group B (n=29), group C (n=28) and group D (n=30). All patients were trained with conventional comprehensive rehabilitation therapy for four weeks, while the group B and group C were respectively trained with MVF and mCIMT based on conventional comprehensive rehabilitation therapy. Finally, the group D was simultaneously trained with MVF and mCIMT. The investigation duration was set as four weeks for all groups. The Fugl-Meyer Assessment (FMA) score, Upper Extremity Function Test (UEFT) score, and Modified Barthel Index (MBI) score were used as main index of clinical effects. Results After treatment, the scores of FMA, UEFT and MBI were respectively (26.37±3.44),(43.30±3.46),(56.27±4.76) in group A, (29.17±2.82), (45.41±3.40), (58.72±4.48) in group B, (29.46±3.16), (45.71±2.37), (58.82±3.89) in group C, (31.93±2.74), (48.83±3.57), (62.17±4.51) in group D.Comparing with the scores before treatment, the paired-sample t test showed that there were significant differences (P<0.05). The single factor variance test showed that the scores of the group D were significant better than those scores in group A, group B and group C (P<0.05); furthermore the scores of the group B and group C were significant better than the group A (P<0.05). However, there were no difference at those scores between the group B and group C (P＞0.05). Conclusion Based on conventional comprehensive rehabilitation, single combined with MVF or mCIMT may significantly improve the function of upper limb and activities of daily living (ADL) in post-stroke patients with hemiplegia. However, simultaneous combined with MVF and mCIMT will be more effective than the single one.

Objective We realized that EGF could play an important protective role against NEC. However, the practical condition of the distribution and expression of EGF in intestine of infants with NEC was indefinite. In order to figure out this problem,we carried out this experimentation. Methods The sample were divided into two group.The experimental group(necgroup) were composed of fifteen individual intestinal tissues after the ileostomy were performed on those infants suffered from NEC. The control group(sealing fistula group) were composed of fifteen individual intestinal tissues after the ileal closure fistula were performed on the same infants who were accepted the one-stage ileostomy in the period of NEC and were later accepted the two-stage operation on the condition that their bodies almost recovered from NEC after two to three months gone.Then, we utilized immunohistochemistry to test the distribution and quantities of EGF on those samples of the two group infants. Results The characteristic of EGF expression in intestine of the both group included strong positive expression in mucous layer and less expression in strata submucosum and muscular coat. The average optical density in nec group was mucous layer (0.241±0.075),strata submucosum(0.213±0.026),muscular coat (0.1397±0.022);In the control groupmucous layer (0.211±0.028),strata submucosum (0.119±0.022),muscular coat (0.097±0.007). The expression of EGF in intestinal tissues increased in the period of NEC0.198±0.071 by comparing with the control group (0.146±0.058). Conclusion There may be a correlation between the strong positive expression of EGF in intestinal tissues in the period of NEC and inflammation.By combining the result of this experiment and the research about EGF. We assumed that EGF is one factor of the protective mechanism by which injured intestinal mucous could be recovered and resist inflammation.
