Chinese Journal of Behavioral Medicine and Brain Science 2010;19(6):492-494
Objective To compare the differences of dysfunctional attitudes between depressive patients in remission with and without personality disorder (PD).Methods A total of 72 patients with remitted depression were assessed with Personality Diagnostic Questionnaire-4 (PDQ-4) and Dysfunctional Attitudes Scale (DAS).They were divided into PD group ( n = 20 ) and non-PD group ( n = 31 ) according to their PDQ-4 scores.The differences of dysfunctional attitudes between the two groups were compared.Results The total score and seven factors' scores of DAS of the PD group were ( ( 142.40 ± 20.68 ), ( 16.55 ± 3.76), ( 16.35 ± 5.45 ),( 18.35 ± 4.15 ), ( 17.90 ± 3.55 ), ( 18.85 ± 5.72 ), ( 18.25 ± 4.82 ), ( 20.75 ± 5.54) respectively) significantly higher than the counterparts of the non-PD group, which were( ( 113.61 ± 19.08 ), (13.71 ± 2.88 ), ( 12.45 ±2.87) ,(12.55 ±3.60),(13.90 ±3.72) ,(14.68 ±3.51),(14.16 ±4.12),(15.81 ±4.78)) respectively (P< 0.01 ).Conclusion Remitted depressive patients with personality disorders have more cognitive distortions than those without personality disorders.

Object To study the pharmacokinetics of loganin in LIUWEI DIHUANG DECOCTION (LWDHD) in mice. Methods HPLC-UV detection was used to determine the loganin levels in biological samples. Results After ig LWDHD in mice, the plasma concentration-time course fitted well to one-compartment model with the 1st order absorption and with the following pharmacokinetic parameters; Ka= 0.04min -1, Ke=0.019 min -1, T (peak)=42.4 min, t 1/2ka=17.4 min, t 1/2ke=35.75 min. Conclusion The pharmacokinetic parameters of loganin obtained in the study may be attributed to the effect of other constituentsin the DECOCTION.

OBJECTIVE To explore the absorption mechanism of thiophenorphine, and its effect on P-glycoprotein (P-gp) expression by using Caco-2 cell monolayer model. METHODSThe LC-MS-MS method was applied to determine thiophenorphine concentration in millicell system. The bi-directional permeability studies were performed to investigate the potential involvement of efflux carriers in the intestinal absorption. P-gp inhibition was studied by flow cytometry using calcein-AM as P-gp substrate.The expression of P-gp was evaluated using Western blotting. RESULTSThiophenorphine transport in Caco-2 cells was in time-dependent manner. Its average apparent permeability coefficient (P_(app)) was 2.338×10~(-6) cm·s~(-1). P_(app) was increased 2.8 folds by P-gp inhibitor ciclosporin A, and 2.3 folds by mulitdrug resistance-associated protein2 (MRP2) inhibitor MK571. The accumulation of calcein-AM and the expression of P-gp in Caco-2 cell line wasn't changed noticeably by thiophenorphine. CONCLUSION Thiophenorphine is a common substrate of P-gp and MRP2 and it shows normal transport in millicell system. The expression of P-gp doesn't induce by thiophenorphine.

This study is to investigate the effect of curcumin on the induction of glutathione Stransferases (GST) and NADP(H):quinone oxidoreductase (NQO) and explore their possible molecular mechanism. The activity of GST, NQO and cellular reduced glutathione (GSH) content were measured by spectrophotometrical methods. Cellular changes in the distribution of NF-E2 related factor 2 (Nrf2) were detected by Western blotting analysis. Nrf2-AREs (antioxidant-responsive elements) binding activity was examined by electrophoretic mobility shift assay (EMSA). Treatment of HT-29 human colon adenocarcinoma cells with curcumin dramatically induced the activity of GST and NQO at the range of 10-30 μmol·L-1. Curcumin exposure caused a significant increase in cellular GSH content rapidly as early as 3 h. Moreover, curcumin triggered the accumulation of Nrf2 in nucleus, and increased Nrf2 content in ARE complexes. These results demonstrated that induction of GST and NQO activity by curcumin may be mediated by translocation of transcription factor Nrf2 from cytoplasm to nuclear and increased binding activity of Nrf2-ARE complexes.

Objective To investigate the correlative factors influencing long-term efficacy of patients with liver neoplasms after interventional therapy. Methods A total of 495 patients underwent transcatheter arterial chemoembolization (TACE), and the data were retrospectively analyzed. The patients were divided into two groups according to the survival time after interventional therapy: ≥5 years and <5 years. Correlative factors were compared in both two groups. Results In 31 patients survived longer than 5 years, 18 patients with Lipiodol filling type Ⅰ tumor, and 13 with type Ⅱ tumor. The 5, 7, 10 years survival rate in all 495 patients was 6.26% (31/495), 1.41% (7/495) and 0.40% (2/495), respectively. Factors including tumor pattern, clinical classification, the features of angiography, with or without heptic arteriovenous fistula, the pattern of Lipiodol filling, with or without invasion and metastasis, hepatic function, patient's age, tumor diameter, AFP value before and after TACE, the variety of AFP value after TACE influenced the long-term survival rate after interventional therapies (P<0.05). Conclusion The characteristics of tumor, patient's status, the quality of TACE, whether combined with PEI, and/(or) anti-virus treatment have significant influence on long-term efficacy after interventional therapy in patients with liver neoplasms.

Objective To study the effects of the clinical pathway on hip arthroplasty. Methods Fifty patients with hip arthroplasty were selected. Twenty-three cases in the control group were treated with traditional methods, and 27 cases in the experimental group were applied with the clinical pathway for standardized treatment. Any differences in Harris scores, hospital costs and days in postoperative care at 1 week and 3 months were compared statistically between the two groups. Results Complications, hospital costs and average length of stay in postoperative care were significantly lower in the experimental group than among the controls. The Harris scores in postoperative week 1 were significantly higher in the experimental group than among the controls. Conclusion The clinical pathway using standard diagnosis and treatment can not only decrease hospital costs and average length of stay, it can also limit postoperative complications and quickly improve joint function, giving better quality medical care.

OBJECTIVE To synthesize[3H]labelled trantinterol and determine the mass balance in rats and the profile of trantinterol and its metabolites in excreta. METHODS [3H]Trantinterol was synthesised from the intermediate1-(4-amino-3-chloro-5-trifluoromethyl-phenyl)-2-bromo-ethanone through reduction by sodium borotritide and aminolysis by t-butylamine. Following an oral dose of[3H] trantinterol(45.5 MBq·kg-1)to bile duct cannulated(BDC)rats and normal rats. Bile,urine and faeces were collected individually before and after dosing at different times. Liquid scintillation counter(LSC) was used to detect total radioactivity recovery and HPLC/radio-detector for metabolite profiling in urine and bile. RESULTS The majority(73.6%)of the administered radioactivity was recovered in the first 24 h postdose with 48.3%in urine and 25.4%in faeces. It was cumulated to(84.7±6.8)%till 168 h. In BDC rats,29.3%of the dose was recovered in the bile 3 d post-dose. According to the peak area ratio determined by HPLC/radio-detector,only 4.7%and 9.5%of the radioactive dose were excreted as the parent drug in urine and bile,respectively,while the majority of the remaining radioactivity was excreted in the form of various metabolites. CONCLUSION Following oral administration in rats,trantinterol is completely absorbed,extensively metabolized and rapidly excreted mainly in urine as various metabolites.
