目的 对比观察单孔、单操作孔及三孔胸腔镜治疗早期非小细胞肺癌(NSCLC)的临床疗效。方法 选择125 例早期NSCLC患者,分为单孔组(38例)单操作孔组(42例)和三孔胸腔镜组(45例),观察3组手术结果和并发症发生率。结果 3组患者均顺利完成手术,无中转开胸。单孔组手术时间长于单操作孔及三孔组,差异有统计学意义(P＜0. 05)。对比所有3组手术患者的术中出血量及淋巴结清扫数目、术后总引流量及引流管留置时间、术后并发症发生率,差异无统计学意义(P＞0. 05)。单孔组及单操作孔组术后疼痛程度评分优于三孔组,差异有统计学意义(P＜0. 05)。结论 单孔及操作孔胸腔镜治疗早期NSCLC已可取代三孔胸腔镜技术,其术后恢复快,疗效确切,其中单孔手术对设备及胸腔镜医师操作技术熟练程度等要求更高,故在设备仍未有突破性的进展时,单操作孔胸腔镜手术可作为治疗早期NSCLC的优先选择。

Objective To compare the clinical effects of uniportal video-assisted thoracic surgery (VATS), single utility port VATS and 3-portal VATS lobectomy for patients with early stage non-small cell lung cancer. Methods Patients were divided into uniportal VATS lobectomy group(n=38), single utility port VATS lobectomy group(n=42) and 3-portal VATS lobectomy group (n=45). The surgical results and complication rates were observed. Results All patients completed the operation successfully, no one was changed to open operation. Operation time in uniportal VATS lobectomy group were longer than single utility port VATS lobectomy group and 3-portal VATS lobectomy group(P＜0. 05). There were no significant differences in intraoperative blood loss, number of lymph node dissection, the amount and time of postoperative extubation, and the incidence of postoperative complications(P＞0. 05). Post-operative pain score were higher in 3-portal VATS lobectomy group than in uniportal VATS lobectomy group and single utility port VATS lobectomy group (P＜0. 05). Conclusion Uniportal VATS lobectomy and single utility port VATS lobectomy can replace the 3-portal VATS lobectomy in treatment of early NSCLC, because of the faster postoperative recovery and curative effect. Uniportal VATS lobectomy requires special equipment and more operation skills, as there is no breakthrough in the equipment, single utility port VATS lobectomy may still be used as the first choice for treatment of early NSCLC.

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.
