Efficacy and safety of agomelatine and SSRIs in the treatment of depressive disorder： a network Meta-analysis / 四川精神卫生

ObjectiveTo evaluate the efficacy and safety of agomelatin and selective serotonin reuptake inhibitors （SSRIs） in the treatment of depressive disorder via network Meta-analysis. MethodsThe literature databases such as China National Knowledge Network （CNKI）， Wanfang Data Knowledge Service Platform， VIP Database for Chinese Technical Periodical （VIP）， Chinese Biomedical Literature Database （CBM）， PubMed， Embase and Cochrane Library were searched from the inception to November 2021. Based on the preset inclusion and exclusion criteria， literature screening， quality assessment of methodology and data extraction were conducted by two researchers separately， then statistical analysis was carried out using ADDIS software. ResultsA total of 7 256 patients with depressive disorder in 22 randomized controlled trials were included. According to the consistency assessed in Bayesian network Meta-analysis and the estimation of the probability of being the best treatment， escitalopram （P=0.63） ranked first for response rate and paroxetine （P=0.31） was associated with the best ranking for cure rate in terms of the effectiveness， meantime， paroxetine （P=0.44） had the highest adverse events risk and sertraline （P=0.74） had the highest study drop-outs proportion in terms of safety. ConclusionEscitalopram and paroxetine may be superior to sertraline， agomelatine， citalopram and fluoxetine in the treatment of depressive disorder， furthermore， paroxetine and sertraline demonstrate poor safety profiles.

Transportation and Absorption of Thermo-sensitive Gel Mediated 5-FU Multiple Emulsion in Caco-2 Cell Monolayer Model / 中国药师

Objective: To develop 5-FU multiple emulsion entrapped into thermo-sensitive gel (5-FU-DEG) and detect the ab-sorption and transportation in Caco-2 cell monolayer model. Methods:The 5-FU multiple emulsion was prepared by a two-step emulsif-ying method. Poloxamer 407 (P407) was used as the thermo-sensitive material and sodium alginate (SA) was used as the bioadhesive material for the preparation of 5-FU-DEG. Caco-2 cell monolayer model was used to investigate the transportation and absorption of 5-FU. Results:5-FU-DEG gelled at the ambient temperature and turned into liquid below 10℃ The apparent permeability coefficient (Papp) of 5-FU-DEG was 1.47 ±0.11 ×10 -5(cm·s-1), which was about 6 times higher than that of 5-FU water solution(2.39 ± 0.21 ×10 -6 cm·s-1)(P<0.01). The cellular uptake rate of 5-FU-DEG was (17.1 ±0.24) %, which was 3.9 times greater than that of 5-FU water solution (4. 41 ± 0. 23%)(P<0. 01). Conclusion:5-FU-DEG can efficiently enhance the transportation and ab-sorption of drug in rectal site by using micro-emulsion technology combined with thermo-sensitive technology, which can be an effective rectal delivery system for 5-FU to treat rectal cancer.

Physicochemical characteristics of coamorphous simvastatin-gliclazide / 中国药科大学学报

@#In this study, coamorphous simvastatin-gliclazide was prepared and characterized. Its single-phase amorphous nature was demonstrated. The hydrogen bond between the O-H group of simvastatin and sulfonylurea C=O group of gliclazide was revealed to be the trigger for the amorphization of gliclazide, which is difficult to form an amorphous state in other methods. Coamorphous simvastatin-gliclazide can significantly enhance the solubility and dissolution of gliclazide, without obvious effect on simvastatin. Compared with amorphous simvastatin, coamorphous simvastatin-gliclazide showed improved physical stability in the cunrent study.
