ObjectiveTo investigate the effect of Quzhi Ruangan decoction on the mRNA and protein expression of organic anion transporting polypeptide 2B1 (OATP2B1) in the small intestine of rats with nonalcoholic fatty liver disease (NAFLD). MethodsAfter 1 week of adaptive feeding, 36 male Sprague-Dawley rats were randomly divided into normal group, model group, simvastatin group, and high-, middle-, and low-dose Quzhi Ruangan decoction groups, with 6 rats in each group. Liver tissue was collected and HE staining was used to observe hepatic steatosis; an automatic biochemical analyzer was used to measure the serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), glucose (GLU), and cholesterol (CHOL); RT-PCR and Western blot were used to measure the mRNA and protein expression of OATP2B1 in the small intestine of rats. A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. Results There were significant differences in liver index, GLU, and CHOL between groups (F=10.814, 12.298, and 5.024, all P＜0.05), and there were also significant differences in the mRNA and protein expression of OATP2B1 in the small intestine (F=13.384 and 73.025, both P＜0.05). Compared with the normal group, the model group had significant increases in the mRNA and protein expression of OATP2B1 (both P＜0.05); compared with the model group, the simvastatin group and the high- and middle-dose Quzhi Ruangan groups had a significant reduction in the mRNA expression of OATP2B1 (all P＜0.05); compared with the simvastatin group, the middle- and low-dose Quzhi Ruangan groups had a significant reduction in the mRNA expression of OATP2B1 (both P＜0.05). Compared with the normal group, the model group had a significant increase in the protein expression of OATP2B1 (P＜0.05); compared with the model group, all treatment groups had a significant reduction in the protein expression of OATP2B1 (all P＜0.001); compared with the simvastatin group, the high-, middle-, and low-dose Quzhi Ruangan groups had a significant reduction in the protein expression of OATP2B1 (all P＜0.05). ConclusionQuzhi Ruangan decoction may alleviate the pathological changes of NAFLD by reducing the overexpression of OATP2B1.

ObjectiveTo explore the related factors of troublemaking behaviors among patients with mental disorders induced by amphetamine-type stimulants （ATS）， and to provide references for the formulation of relevant intervention measures for ATS-induced mental disorders. MethodsA total of 105 patients who met the diagnostic criteria of International Classification of Diseases， tenth edition （ICD-10） for ATS-induced mental disorders were included， and classified into troublemaking group and non-troublemaking group. The general demographic data and clinical data of the selected individuals were collected， and all patients were assessed using Social Support Rating Scale （SSRS）. Then univariate analysis and multivariate Logistic regression model were used to screen the related factors of troublemaking behaviors. ResultsThe scores of SSRS， objective support dimension and social support utilization dimension were significantly lower in troublemaking group than those in non-troublemaking group， with statistical differences ［（24.10±6.59） vs. （28.94±5.59）， t=3.364， P=0.001； （5.50±1.96） vs. （8.20±2.13）， t=5.183， P<0.01； （4.60±2.26） vs. （6.28±1.90）， t=3.435， P=0.001］. Multivariate Logistic regression analysis showed that male （OR=6.061， P=0.014） was a risk factor， while high social support level （OR=0.873， P=0.018） was the protective factor for troublemaking behaviors among patients with ATS-induced mental disorders. ConclusionPatients with ATS-induced mental disorders of the males and with low social support level are at high risk of troublemaking behaviors.
