Purpose:
To investigate the relationship between rumination, coping strategies, and subjective well-being (SWB) and test the mediating effects of coping strategies on rumination and SWB in patients with breast cancer (BC).
Methods:
This cross-sectional study assessed rumination, coping strategies, and SWB using the General Well-being Schedule, the Chinese Event-Related Rumination Inventory, and the Medical Coping Modes Questionnaire in BC patients admitted to a tertiary general hospital in China.
Results:
SWB was positively associated with the total score for rumination (r = .32, p < .01), deliberate rumination (r = .75, p < .01), and confrontation (r = .58, p < .01). The relationship between rumination and SWB was mediated by confrontation (indirect effect = .74).
Conclusion
BC diagnosis can affect patient's SWB. These findings indicate that rumination and confrontation have direct and indirect effects on SWB. Therefore, psychological interventions focused on improving coping may increase SWB. Notwithstanding, larger longitudinal studies are needed to further examine the relationship between cognitive processes, coping strategies, and SWB.

OBJECTIVETo investigate the influence of drug properties on the encapsulation effiency (EE) and drug release of transfersomes for a proper transfersome preparation.
METHODTo prepare the transfersomes of colchicines (CLC), vincristine sulfate (VCR) and mitoxantrone hydrochloride (DHAD) with the same materials and methods, and then measure their EE. To find out the relationship between drug properties like solubility, molecular weight and charges, and EE. To performe the drug release experiments of various types of transfersomes in vitro, and compare their differences.
RESULTVCR and DHAD are lipophilic or hydrophilic, owing positive charges and large molecular weight, as a result, their EE are high, while CLC is amphipathic, neutral, and of small molecular weight, its EE is very low. As DHAD can insert into the membrane of transfersome, the drug release of DHAD-T in vitro is much slower than that of VCR-T.
CONCLUSIONTo prepare transfersomes with high EE, drugs that are lipophilic or hydrophilic, high molecular weight and opposite charges to the membrane should be chosen. Interaction between drugs and membrane will influnce the rate of drug release.

The paper reports the systematic study on felodipine and its impurities in tablets, to improve its quality standards for the control of the related substances. HPLC-DAD, UPLC-MS, IR and NMR methods were used for the isolation of felodipine and its impurities in tablets, their identification and the zebrafish animal model was used for the analysis of the toxic impurities. In felodipine material and its tablets, three impurities are isolated and identified. They are impurity 1 [dimethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], impurity 2 [ethyl methyl 4-(2, 3-dichlorophenyl)-2, 6-dimethylpyridine-3, 5-dicarboxylate] and impurity 3 [diethyl 4-(2, 3-dichlorophenyl)-2, 6-dimethyl-1, 4-dihydropyridine-3, 5-dicarboxylate], separately. The result of zebrafish animal model analysis showed that the teratogenic effects of four compounds were: impurity 3 > or = felodipine > impurity 1 > impurity 2, lethal effects were as follows: impurity 2 = impurity 3 > felodipine > or = impurity 1. This study confirmed the toxicity of three impurities in felodipine. According to the results, the paper suggested the amendments to the standard of the medicine and provided the support to the control of impurities in the manufacturing process.
