Objective To set up a simple and accurate method for the determination of total Glucosides in Paeonia lactifloria (TGP) by HPLC.Methods Benzoic acid being as contiol,the amounts of TGP were obtained from the following formula :TGP( ) = benzoic acid() ?480. 27/ 121. 121. Benzoic acid was determined by HPLC. Chromatographic conditions concluded YMC-Pack ODS-A(5?m,150?4.6mm)column and the mobile phase consisting a mixture of MeOH - 0.05mol?L - 1KH2PO4 - HAC - isopropanol (85:155:4:6). Benzoic acid was detected at 230nm wavelength.Results The calibration curves of Benzoic acid were in good linearity over the range of 0.1~2g(r=1.0000). The average recovery of Benzoic acid was 101.12(n=9,RSD=2.49). Conclusion This method is simple and can be easily repeated.

Objective To analyze the differences in social psychological characteristics of patients with different subtypes of functional dyspepsia (FD).Methods From August 2011 to July 2015,210 FD patients met Rome Ⅲ criteria were enrolled and divided into pure postprandial distress syndrome (PDS)group (69 cases),pure epigastric pain syndrome (EPS) group (74 cases) and PDS overlap EPS (PDS+ EPS) group (67 cases).Hamilton depression scale (HAMD),Hamilton anxiety scale (HAMA),life event scale (LES) and Eysenck's personality questionnaire (EPQ) were used for evaluation.Chi-square test and least-significant difference were performed for statistical analysis.Results Incidence rates of depression and anxiety of PDS+EPS group were both 100.0％ (67/67),which were higher than those of pure PDS group (84.1％,58/69 and 91.3％,63/69),and the differences were statistically significant (x2 =11.62 and 16.34,both P＜0.01);which were also higher than those of pure EPS group (78.4％,58/74 and 90.5％,67/74),and the differences were statistically significant (x2 =6.10 and 6.67,both P＜0.05).Somatic anxiety score and mental anxiety score of PDS+ EPS group were 16.34±3.70 and 14.18±2.99,respectively;which were higher than those of pure PDS group (11.26±3.42 and 10.70±2.94) and pure EPS group (12.30 ± 4.29 and 10.36 ± 2.63),and the differences were statistically significant (t=8.33,5.97,6.85 and 8.06;all P＜0.01).The top two life events in three groups were sleeping habits alteration (67.6％,142/210) and severe disease or trauma (26.7％,56/210).The incidence rate of sleeping habits alteration in pure PDS group was 53.6 ％ (37/69),which was lower than that in pure EPSgroup (77.0％,57/74) and PDS+EPS group (71.6％,48/67),and the differences were statistically significant (x2 =8.68 and 4.71,both P＜0.05).Most of P scale scores of pure PDS group,pure EPS group and PDS+EPS group were normal,most of E and L scale scores were low;most of N scale scores of pure PDS group were low,and these of pure EPS group and PDS+EPS group were normal.Conclusions The incidence of depression and anxiety of PDS+EPS group is the highest.Somatic anxiety is more obvious than mental anxiety in PDS+EPS group and pure EPS group,most with sleep events.Slow emotional response is common in pure PDS group.
