Objective To examine the reliability and validity of the Suicidal Behaviors Questionnaire-Revised(SBQ-R)among Chinese undergraduates and to find out cut-off score for screening the risk of suicide in clinical undergraduates.Methods A total of 488 Chinese undergraduates participated in this study.Of them,366 participants were asked to complete the Chinese version of SBQ-R,Psychache Scale,and Satisfaction with Life Scale.And 45 undergraduates were re-tested after four weeks;122 undergraduates were tested by using the Suicidality Module Section of the Mini International Neuropsychiatric Interview and the Chinese version of SBQ-R.Results ① The results showed that The Chinese version of SBQ-R had one factor with good fit indices.② The internal consistency reliability,split-half reliability,and one-month retest reliability of the total questionnaire were 0.76,0.79,and 0.93,respectively.③ The total score of the SBQ-R in Chinese was positively correlated with psychache but negatively correlated with satisfaction of life,indicating that the scale has good criterion-related validity.④ Receiver operating characteristics(ROC)curve evaluation suggested that the cut-off score was 9 in terms of identifying the clinical undergraduates at high risk of suicide.Conclusion SBQ-R is a reliable,valid,and practical instrument to measure the risk of suicide among Chinese undergraduates.SBQ-R＞9 is the best cut-off value for screening for high suicide risk in China.

Objective:To explore the cost control effect and cost-shifting effect of Diagnosis-Intervention Packet(DIP)payment reform on inpatient coronary heart disease patients.Methods:Z City,a national pilot city for DIP,is taken as a case study.It utilizes inpatient claims data and the propensity scoring matching-difference in differences method to evaluate the impact of DIP payment reform on total medical expenses,Out-of-Pocket(OOP),the OOP proportion,self-paid Category B expenses,the proportion of self-paid Category B expenses,Category C expenses,and the proportion of Category C expenses for coronary heart disease inpatients.Results:After the DIP reform,the total medical expenses per inpatient coronary heart disease patient significantly decreased(β=-0.127,P＜0.01).Regarding cost-shifting,the OOP expenses(β=0.108,P＜0.05),the OOP proportion(β=0.055,P＜0.01),self-paid Category B expenses(β=0.239,P＜0.01),the proportion of self-paid Category B expenses(β=0.030,P＜0.01),and the proportion of Category C expenses significantly increased(β=0.026,P＜0.01),while there was no significant change in Category C expenses.Conclusion:The DIP reform significantly reduced the total medical expenses per inpatient case of coronary heart disease.At the same time,the reform shifted costs from within the scope of the insurance policy to outside the policy's coverage,with a stronger shift observed from Category B to Category C expenses.

Objective:To summarize initial experience of applying nanopore third-generation sequencing detection method (nanopore sequencing) for genetic diagnosis of non-classical 21 hydroxylase deficiency (NC 21-OHD), and to explore its performance and application prospects.Methods:Clinical data of the two NC 21-OHD patients, who were hospitalized at the First Affiliated Hospital of Zhengzhou University in May 2019, were collected. Peripheral venous blood was collected and genome DNA extracted. Genetic variants was detected by nanopore sequencing and underwent bioinformatic analysis. Pathogenetic mutations in CYP21A2 gene were validated with PCR-sanger sequencing in the two patients and their parents.Results:The average reads length and sequence depth in the patient one was 12, 792 bp and 27.19×. The average reads length and sequence depth in the patient two was 13, 123 bp and 21.34×. Compound variants of c.293-13C>G/c.844G>T (p.Val282Leu) and c.332_339delGAGACTAC (p.Gly111Valfs)/c.844G>T (p.Val282Leu) were detected in these two patients, which were consistent with clinical phenotype of NC 21-OHD. Further analysis showed that c.293-13C>G mutation was inherited from her father and c.844G>T (p.Val282Leu) mutation was inherited from her mother for the patient one. The c.844G>T (p.Val282Leu) mutation was inherited from her father and c.332_339delGAGACTAC (p.Gly111Valfs) mutation from her mother.Conclusions:The heterozygous mutations in CYP21A2 gene are the cause of NC 21-OHD in these two patients. Nanopore sequencing technique is a reliable new detection method for patients with NC 21-OHD.
