Objective To explore the necessities and clinical value of acute intestinal obstruction with com-puted tomography of whole abdomen in over 80 years old patients.Methods 50 patients with acute intestinal obstruc-tion were diagnosed in department of emergency surgery and underwent the abdominal CT examinations.The clinical data,CT and surgery pathology of all patients were compared and analyzed.Results All cases were verified by surgi-cal operation and pathological diagnosis,including colorectal cancer(n =21)and incarcerated abdominal external her-nia(n =21),appendicitis(n =2),adhesive intestinal obstruction(n =2),intestinal volvulus (n =2),and intestinal intussusception(n =1)and stercoral intestinal obstruction(n =1),12 cases were accompanied by bowel necrosis and perforation.12 patients were treated by laparoscope surgery,38 cases by open laparotomy,48 patients acquired good recovery,and 2 cases died from extensive bowel necrosis and multi -organ failure.Conclusion CT examination in whole abdomen could rapidly and accurately diagnose the cause of intestinal obstruction,evaluate complications and risks,so as to provide reasonable treatment choice and time,making patients acquired the effective effects as soon as possible,reducing the bad consequences.

Objective To establish a model of cervical spondylosis in rats. Methods Sixty SD rats (four months old) were ran-domly divided into control, muscle imbalance and posterior column instability group, ten rats in each group. Then the degeneration of X-ray film and motion function were evaluated by oblique board test. Results After analyzed the cervical films of control groups, the nature curve still existed, vertebral clearance had no abnormal. No ostensis spurs or ossifies in Luschka joint and joint processes were found. But in mus-cle imbalance and posterior column instability groups, the nature curve was disappeared or stiff, vertebral clearance were stenosis, osteosis spur formed, ossify or sclerosis emerged in Lnschka joint and joint process. Compared with control group in oblique board test, the muscle force decreased in muscle imbalance and posterior column instability group. There were no statistic significant difference between 2 and 4 months of control group, and also no difference in muscle imbalance and posterior column instability group, but there were significant differ-ence in 2 and 4 months of muscle imbalance and posterior column group. Conclusion Not only cervical posterior column instability but also muscle imbalance could result in cervical spendylosis, both muscle force balance and posterior column were important factors in maintaining spine stability.

Objective:To summarize the best evidence of post-stroke insomnia nursing and provide basis for clinical practice.Methods:According to the "6S" pyramid model, the system searched UpToDate, Scottish Interhospital Guidelines Network, US National Guidelines Network, JBI Evidence Based Health Care Center Database, BMJ Best Clinical Practice, NICE Guidelines Network, China Medical Pulse Communication Guidelines Network, Ontario Registered Nurses Network, The Cochrane Library, PubMed, Web of Science, Medline, Embase, CINAHL, CNKI, Wanfang, VIP and Chinese Biomedical Literature Database and related association websites. Evidence on the post-stroke insomnia nursing, including guidelines, systematic evaluations, expert consensus, etc. The retrieval period was from the database construction to February 19, 2022. The quality of the literature was evaluated by the corresponding articles evaluation criteria.Results:A total of 24 articles were selected, including 6 guidelines, 16 systematic reviews and 2 expert consensus. Totally 26 pieces of the best evidence on 5 aspects including the evaluation of sleep quality, the diagnosis of post-stroke insomnia, the development of individual plan, non-pharmaceutical intervention, and traditional Chinese medicine nursing intervention were finally summarized.Conclusions:The summarized evidence of post-stroke insomnia nursing, for can be used to provides scientific and effective evidence-based basis for nursing staff to carry out clinical practice. It is suggested that the specific evidence should be selected according to the specific situation of patients in clinical application.

Objective To compare the diagnostic accuracy of magnifying chromoendoscopy (MCE) and endoscopic ultrasonography (EUS) for preoperative endoscopic assessment of the invasion depth of colorectal laterally spreading tumour(LST).Methods Data of 104 cases of colorectal LST were included.With the final pathological diagnosis as the golden standard,the accuracies of MCE and EUS for preoperative assessment of the invasion depth of colorectal LST were compared.Results The diagnostic accuracies of MCE and EUS for evaluating the invasion depth of LST were 89.4％ (93/104) and 73.1％ (76/104),respectively(P＜0.05).The lesion size and the endoscopist could affect the accuracy of the EUS evaluation (P=0.017,OR=3.561;P=0.035,OR =1.399).The accuracy of EUS seemed to show a downward trend for colorectal LST of larger diameters.Conclusion Both MCE and EUS are effective for evaluating the invasion depth of colorectal LST,but the accuracy of MCE may be higher than that of EUS.Large diameter of the lesion and the doctor's experience inadequacy may be the risk factors for the accuracy of EUS.
