Objective To explore the applicability of the abbreviated Chinese version of the social problem-solving inventory (C-SPSI) for nursing students in Shanghai. Methods The abbreviated C-SPSI was revised and 603 nursing students in Shanghai were surveyed by it, and the reliability and con-struct validity were evaluated by inter-item consistency analysis, test-retest reliability and principal factor analysis. Results The total CVI was 0.968. The construct validity was confirmed by factor analysis with 64.917% variance explained by four factors. The total Cronbach's α of C-SPSI was 0.897,and the total test-retest reliability coefficient was 0.781. Conclusions The abbreviated C-SPSI is an instrument with good reliability and validity and it can be used in assessing the nursing students' social problem-solving abilities and deficits.

AIM To optimize the ultrasound-microwave extraction for total flavonoids from Glycyrrhizae Radix et Rhizoma residue by response surface method.METHODS In addition to the index of extraction rate of total flavonoids for evaluation,the microwave power,extraction time,liquid-soild ratio and ethanol concentration were taken into consideration as influencing factors for the extraction optimization by response surface method on the basis of single factor test.RESULTS The optimal conditions,determined to be 125 W for microwave power,32 min for extraction time,28.4 ∶ 1 for liquid-solid ratio,79% for ethanol concentration,and 300 W for extraction power,could bring forth a 2.59% extraction rate of total flavonoids.CONCLUSION This stable and reliable method can be used for extracting total flavonoids from Glycyrrhizae Radix et Rhizoma residue.
