Background: Developed based on the Clinical Assessment Interview for Negative Symptoms (CAINS), the Motivation and Pleasure Scale-Self Report (MAP-SR) was designed to address the conceptual and psychometric limitations of other instruments assessing negative symptoms. We sought to validate and extend the applicability of the MAP-SR in the Chinese context across the schizophrenia spectrum., Methods: Three samples, including college students, individuals with social anhedonia and patients with schizophrenia, were recruited. Test-retest reliability, internal consistency, factor structure, and convergent/discriminant validity of the MAP-SR were examined. The group differences between the three participant groups were examined., Results: A four-factor structure of the MAP-SR was found consistently in all three groups of participants. The scale showed convergent/discriminant validity in patients with schizophrenia and individuals with social anhedonia, along with good reliability found in schizophrenia patients. The MAP-SR was also able to distinguish individuals with SocAnh and patients with SZ from matched controls., Conclusions: The MAP-SR is a valid and reliable instrument in assessing negative symptoms in individuals along the schizophrenia spectrum., (Copyright © 2020 Elsevier B.V.

Objective: To investigate the safety and feasibility of thoracoscopic anatomical pulmonary segmentectomy in children with congenital lung malformations., Methods: A retrospective review was conducted to analyze clinical data of children thoracoscopic anatomical pulmonary segmentectomy performed in West China Hospital of Sichuan University from Jan. 2014 to Sept. 2018., Results: A total of 151 cases were recorded, including 73 males and 78 females. The average age was 9.8 months, ranging from 5 months to 13.3 years. All the patients underwent thoracoscopic surgery without conversion to open. The average operation time was 66 min, the average amount of bleeding was 5.9 mL and the average size was 4.8 cm. Two children had air leakage after the operation, but recovered after one-week tube drainage and conservative observation therapy. 56 children had postoperative fever in varying degrees, which gradually recovered 2-3 d after operation. No postoperative complications occurred such as bronchial fistula, hemorrhage, atelectasis and pulmonary infection. Postoperative pathological results showed that there were 108 cases of congenital pulmonary airway malformation and 43 cases of intralobar pulmonary sequestration. The median follow-up time was chest computed tomography of follow-up showed that all patients recovered well without recurrence., Conclusion: On the basis of thoracoscopic meticulous anatomy of lung lobes, Thoracoscopic anatomical segmentectomy in children is safe and feasible as a lung sparing resection., (Copyright© by Editorial Board of Journal of Sichuan University (Medical Science Edition).)
