ObjectiveTo explore the relationship between the mRNA and protein expressions of NIX and the pulmonary alveolus apoptosis following severe acute lung injury (ALI).Methods Rat models of severe collision injury on the chest were built.The mRNA and protein expressions of NIX in the alveolar cells at 6,12,24,48,72 and 96 hours after injury were detected using immunohistochemistry,immunoblotting and RT-PCR.Meanwhile,apoptosis of the alveolar cells was checked at different time points with Tunel assay.ResultsThe protein expression of NIX in the alveolar cells was observed both in experimental and control groups,which increased at 6 h post injury,peaked at 48 h and then declined till approaching the pre-injury level at 96 h.In the meantime,NIX showed a high expression both in the vascular endothelial cells (VECs) and the renal interstitial fibroblasts.The apoptosis of alveolar cells mainly presented in bronchi,blood vessel endothelium (BVE) and alveolar epithelium at 24 h post injury.The post-injury apoptosis rate of the alveolar cells was significantly higher than the pre-injury rate ( P ＜ 0.01 ),which reached the peak at 72 h and then decreased gradually.The changes of NIX protein in lung tissue showed a positive correlation with the apoptosis rate of alveolar cells after injury (r =0.303,P ＜ 0.01 ).ConclusionsThe up-regulated expression of NIX takes part in the pathophysiological process of apoptosis of the alveolar cells and shows consistency with the apoptosis rate change of the alveolar cells,as may be the molecular basis for apoptosis of the alveolar cells after ALI.

Objective To investigate the effect of corpectomy decompression by subtotal vertebrectomy and fusion of adjacent segmental artificial disc replacement through anterior intervertenral spance (Hybrid Surgery) in the anteriorcervical spondylotic myelopathy treatment . Methods Hybrid Surgery were operated on 18 patients who suffered from anterior cervi?cal spondylotic myelopathy . Follow up of 1-50 months. Patient’s conditions were assessed according to the Japanese Associ?ation for Department of orthopedics assessment score (JOA score) before and after operation. Effects of Hybrid operation were assessed by the improvement of JOA score, Odom’s follow-up grade and cervical mobility . Results The JOA scores of all 18 operated patients were improved from 10.6 ± 1.7 before operation to 13.5 ± 2.4 after operation. And the difference is statistically significant (t=1.314, P < 0.05). Among all the operated patients, 16 were cured and 2 were effective. As to Odom’s follow up grades, 6 cases were excellent, 11 cases were good and 1 case was acceptable. The postoperative move?ment range of cervical spine (40.1° ± 8.4°) show no statistically difference compared with that in preoperation (42.6° ± 11.9°) (t=0.68, P > 0.05). Conclusion Hybrid Surgery of anterior cervical decompression and fusion can both improve the nerve function and preserve cervical mobility.

Background: Prolonged postoperative ileus (PPOI) is a major complication of colorectal surgery. Increased opioid consumption has been proposed to increase the risk of PPOI. This study aimed to test the hypothesis that an increased total postoperative opioid dose (TPOD) is associated with the increased incidence of PPOI. Methods: For this matched case-control study, patients who underwent elective laparoscopic colorectal procedures at the Peking University People’s Hospital between January 2018 and June 2020 were retrospectively reviewed. Patients with PPOI were assigned to the ileus group, while patients without PPOI (control group) were matched at a 1:1 ratio to the ileus group according to age, American Society of Anesthesiologists physical status score, and type of surgical procedure. The primary outcome was the TPOD between the ileus and control groups. The secondary outcome was risk factors of PPOI. Results: A total of 267 participants were included in the final analysis. No differences in baseline or operative factors were found between the two groups. The TPOD, intravenous sufentanil dose on postoperative day 1 (POD1), and the use of patient-controlled analgesia with basal infusion were associated with PPOI (P < 0.05). Multivariate logistic regression analysis revealed that an increased TPOD was an independent risk factor for developing PPOI after laparoscopic colorectal procedures (Odd ratio: 1.67, 95% CI [1.03, 2.71], P = 0.04). Conclusions The TPOD is an independent risk factor for PPOI after laparoscopic colorectal surgery. We need to explore new strategies of postoperative analgesia to reduce the dosage of TPOD.

The medical assistance to advanced schistosomiasis patients established by the Chinese government is a major public facility for patients with advanced schistosomiasis. Since the medical assistance to advance schistosomiasis patients in Hu?nan Province started ten years ago,a set of mature and operable programs with whole program management and related technolo?gies has been developed. The author investigated the data on medical assistance to advanced schistosomiasis patients in Hunan Province during the last 10 years(from 2006 to 2015)retrospectively,and found that the program had high therapeutic effect and high satisfaction degree of both patients and the society. In order to improve the management of the medical assistance to ad?vanced schistosomiasis patients and share our experiences of the whole program management and related technologies with the colleagues of other provinces,this paper mainly illustrates the experiences of the program,as well as the existing problems and related strategies.

Objective:To systematically review the barriers encountered by nursing staff in the implementation of early activities in adult ICU units.Methods:A systematic search was conducted on CNKI, Wanfang Database, VIP Database, China Biomedical Database, PumMed, Web of Science, Cochrane Library and EMBASE for the research on the obstacles of early activity nursing implementation in adult ICU from the establishment of the database to July 2020, and the final integrated analysis of the included literature was carried out.Results:A total of 26 articles were included, and 59 obstacles in 5 categories were integrated, including 6 kinds of technical level, 13 kinds of organizational culture level, 7 kinds of personnel level, 4 kinds of structural level, and 29 kinds of 6 sub categories of patients level. The most frequent obstacles were unstable condition of patients, sedation or continuous deep sedation, low staffing level, disturbance of consciousness of patients, insufficient equipment related to early activities, and low willingness or compliance of patients to participate.Conclusion:The nursing staff are facing with many obstacles in guiding and assisting ICU adult patients to carry out early activities. It is necessary to formulate modified policies aiming at changeable factors in order to promote the application of early activities in adult ICU units.

Background and objective Localization of pulmonary ground glass small nodule is the technical dif-ficulty of minimally invasive operation resection. The aim of this study is to evaluate the value of intraoperative computed tomography (CT)-guided localization using a hook-wire system for small ground glass opacity (GGO) in minimally invasive resection, as well as to discuss the necessity and feasibility of surgical resection of small GGOs (<10 mm) through a minimally invasive approach.MethodshTe records of 32 patients with 41 small GGOs who underwent intraoperative CT-guided double-thorn hook wire localization prior to video-assisted thoracoscopic wedge resection from October 2009 to October 2013 were retrospectively reviewed. All patients received video-assisted thoracoscopic surgery (VATS) within 10 min atfer wire localiza-tion. hTe effcacy of intraoperative localization was evaluated in terms of procedure time, VATS success rate, and associated complications of localization.Results A total of 32 patients (15 males and 17 females) underwent 41 VATS resections, with 2 simultaneous nodule resections performed in 3 patients, 3 lesion resections in 1 patient, and 5 lesions in a patient. Nodule di-ameters ranged from 2 mm-10 mm (mean: 5 mm). hTe distance of lung lesions from the nearest pleural surfaces ranged within 5 mm-24 mm (mean: 12.5 mm). All resections of lesions guided by the inserted hook wires were successfully performed by VATS (100% success rate). hTe mean procedure time for the CT-guided hook wire localization was 8.4 min (range: 4 min-18 min). hTe mean procedure time for VATS was 32 min (range: 14 min-98 min). hTe median hospital time was 8 d (range: 5 d-14 d). Results of pathological examination revealed 28 primary lung cancers, 9 atypical adenomatous hyperplasia, and 4 nonspe-ciifc chronic inlfammations. No major complication related to the intraoperative hook wire localization and VATS was noted. Conclusion Intraoperative CT-guided hook wire localization is useful, particularly in small GGO localization in VATS wedge resection and has a signiifcantly low rate of minor complications. Lung GGOs carry a 90% risk of malignancy. Aggressive surgi-cal resection of these GGOs is necessary and feasible through the guidance of intraoperative CT localization technique.
