Objective Three common positions have been observed for its influence on the objective indicators of the patients with unilateral lung disease,and the change of subjective symptoms in these patients were collected.Methods The study group consisted of 93 patients who had unilateral lung diseases,each of which was randomly observed for three common positions (healthy side position,affected side position and the horizontal position) for 30 minutes respectively.In these patients,the changes of the objective indictors (heart rate,breathing,blood oxygen saturation,the mean arterial pressure) and subjective symptoms (chest stuffiness,breath is aggravating,etc.) were recorded.Results When using different positions,no statistical difference was observed with the heart rate,breathing,oxygen saturation and mean arterial pressure,whereas when affected side position was taken,the occurrence of worrisome symptoms was obviously higher than the condition when using healthy side position and the horizontal position.There was no statistical difference between the two groups of healthy side position and the horizontal position.Conclusions The occurrence of worrisome symptoms in the case of affected side po-sition is significantly more than the other two positions,indicating that patients with unilateral pulmonary disease are more willing to adopt the healthy side position and the horizontal position.

Objective:To investigate endoscopic and clinical characteristics of intestinal Behcet′s disease (BD) in children.Methods:General information, clinical manifestations, laboratory tests, imaging examinations and endoscopic characteristics of 14 children with intestinal BD treated in the Department of Gastroenterology, Beijing Children′s Hospital Affiliated to Capital Medical University from January 2016 to March 2020 were retrospectively analyzed.Results:Fourteen children with intestinal BD were recruited, involving 5 males and 9 females with the age of 1 month to 12 years and 11 months [(6.68±3.73) years old], and a median disease course of 6 months.All of them had gastrointestinal symptoms, including 11 cases with abdominal pain, 7 cases with diarrhea and 2 cases with vomiting.Complications of children with intestinal BD included gastrointestinal bleeding, intestinal perforation and stenosis.Extragastrointestinal symptoms included recurrent oral aphthosis in all the 14 cases, fever in 11 cases, skin lesions in 9 cases, vascular manifestations in 8 cases, positive pathergy test in 6 cases, joint manifestations in 5 cases, neurological manifestations in 1 case, and malnutrition in 6 cases.Observed by the endoscopy, lesions were mainly distributed in the distal ileum [61.5%(8/13 cases)]and ileocecal part[53.8%(7/13 cases)], with the main manifestation of ulcer.There were 3 cases with single ulcer and 10 cases with multiple ulcers, including 7 cases with deep and large ulcers.Pathological examinations of endoscopic lesions showed that the main features were mucosa chronic nonspecific inflammation, mucosa chronic active inflammation with ulcer and vasculitis.Conclusions:Clinical manifestations of intestinal BD vary a lot and are non-specific.Some children with intestinal BD may develop severe complications.Endoscopic lesions of intestinal BD have certain characteristics, which contribute to the diagnosis.Gastroenterologists need to be fully aware of intestinal BD.

Objective:To assess the value of double-balloon enteroscopy(DBE)in the treatment of Peutz-Jeghers syndrome(PJS)polyp with intussusception in children.Methods:A total of 14 cases with PJS polyp with intussusception were collected in Gastroenterology Department of Beijing Children′s Hospital Affiliated to Capital Medical University from July 2019 to January 2023.The general information, clinical manifestations, history of surgeries, abdominal ultrasound, enteroscopy and postoperative outcomes were retrospectively analyzed.Results:Fourteen cases with intussusception of PJS(including nine boys and five girls) were enrolled, and the average age was(10.25±2.52)years.There were 21 small intestinal intussusceptions in 14 cases, including eight cases of single intussusception and six cases of multiple intussusceptions.All the patients underwent DBE examination and treatment.A total of 215 small intestinal polyps were removed, no direct complications such as bleeding or perforation were found during the operation.Twelve cases were confirmed intussusception relieved by DBE, and the average maximum diameter of polyps causing intussusception was(4.38±1.43)cm.In addition, DBE did not reach the site of intussusception polyp in one case, and another case developed intestinal obstruction after DBE operation, which were treated by surgery.Conclusion:DBE provides a relatively effective method for the treatment of PJS polyps with intussusception without complete ileus in children.
