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.

Background: Circular RNAs (circRNAs) is correlated with the development and progression of malignant tumor. Recent studies have shown the potentials of some circRNAs in the early diagnosis, screening of therapeutic targets and prognostic judgment of gastric cancer. Aims: To investigate the serum circNRIP1 expression and its clinical significance in the diagnosis, treatment and prediction of prognosis of gastric cancer. Methods: A total of 76 gastric cancer patients diagnosed by pathology from September 2016 to September 2019 at Dujiangyan People's Hospital were enrolled, and 63 healthy individuals were served as controls. Serum circNRIP1 expression was detected by real time fluorescent quantitative PCR, and its correlation with clinicopathological features was analyzed. ROC curve was used to analyze the diagnostic efficiency. Results: Serum circNRIP1 expression in gastric cancer group was significantly higher than that in healthy control group (P<0.01). The circNRIP1 expression in gastric cancer patients was significantly correlated with the differentiation of tumor cells, depth of infiltration, lymph node metastasis and TNM stage (P<0.05). Serum circNRIP1 expression in gastric cancer patients after operative treatment was significantly lower than that before treatment (P<0.05). After 2 years follow-up, serum circNRIP1 expression in survival group was significantly lower than that in death group (P<0.05). ROC curve analysis showed that the sensitivity of serum circNRIP1 expression for gastric cancer was 88.9%, the specificity was 88.2%, and AUC was 0.876. Conclusions: Detecting serum circNRIP1 expression has significant value in the early diagnosis and evaluation of treatment and prediction of prognosis of gastric cancer.

OBJECTIVE: To investigate the risk factors for type 2 diabetes complicated with hypertension in adult residents in Liuyang, Hunan Province, P. R. China.
 METHODS: The residents aged at or over 18 were selected through a method of multi-stage cluster random sampling from 10 towns in Liuyang. Questionnaires, physical measurements and laboratory tests were conducted. Type 2 diabetes complicated with hypertension were served as an experimental group, while simple diabetes, non-diabetes and non-hypertension (healthy control), or non-complication and healthy group (simple hypertension, simple diabetes, and healthy group) were served as control group, respectively. Three kinds of logistic regression model were used to analyze the risk factors for type 2 diabetes complicated with hypertension.
 RESULTS: A total of 5 669 residents were included in the analysis, and the response rate was 97.74%. The results showed that the prevalence of type 2 diabetes complicated with hypertension of residents at or over 18 years old in Liuyang was 2.6% (95%CI: 2.2%, 3.1%). Logistic regression analyses demonstrated that for people at or over 60 years old, obesity and abnormal triglyceride were the independent risk factors for type 2 diabetes complicated with hypertension.
 CONCLUSION Aging, obesity and abnormal triglyceride can increase the risk of type 2 diabetes complicated with hypertension in adult residents in Liuyang.
