Objective To evaluate the clinical features and key points in treatment of ovarian torsion in children. Methods The clinical data of 64 children with ovarian torsion, hospitalized in our hospital from January 2005 to October 2012, were analyzed retrospectively. The clinical manifestations in children of all ages were summarized. The anal examina-tion, B ultrasound examination, CT examination were used for the early diagnosis of ovarian torsion. All children were per-formed laparoscopic surgical exploration. All children were found the typical lower abdominal cramps. The B ultrasound and CT examination showed non-homogeneous mass in pelvic, which suggested the early diagnosis of ovarian torsion. The detec-tion rate of anal examination reached 70.3%(45/64). Results All patients were performed laparoscopic surgical explora-tion. Five patients were treated with ovariectomy. The rest were treated conservatively. The postoperative follow-up was good. Conclusion Ovarian torsion in children was likely to be misdiagnosed. Doppler, CT, anal examination and laparo-scopic operation were important for the early diagnosis and treatment of ovarian torsion.

Objective:To investigate the effects of mindfulness therapy on blood glucose control and quality of life in older adult patients with diabetes mellitus and cognitive impairment.Methods:A total of 313 patients with type 2 diabetes mellitus and cognitive impairment aged over 75 years who received treatment in Xinxiang First People's Hospital from August 2018 to July 2020 were included in this study. They were randomly allocated to the intervention group ( n = 157) and control group ( n = 156). All patients underwent treatments for diabetes mellitus and underlying diseases. The intervention group was subject to 8 weeks of mindfulness therapy. The percentage of patients with qualified glycosylated hemoglobin in human whole blood and 36-Item Short Form Health Survey questionnaire score were compared between the two groups. The Pearson correlation was performed. Results:After 8 weeks of treatment, the percentage of patients with qualified glycosylated hemoglobin in human whole blood in the intervention group was 43.95%, which was significantly higher than the level (25.48%) at the recruitment and the level (30.77%) in the control group ( χ2 = 12.17, P = 0.002; χ2 = 5.80, P = 0.016). The quality of life score was significantly higher in the intervention group than in the control group [(72.16 ± 14.08) points vs. (64.37 ± 15.49) points, t = 4.65, P = 0.001]. Conclusion:Mindfulness therapy can regulate blood glucose level and improve quality of life in older adult patients with diabetes mellitus and cognitive impairment.
