Cardiovascular disease in peri-menopausal period is a kind of climacteric syndrome which based on the symptoms of the cardiovascular system as the main manifestations. It is manifested as hypertension,pseudo-angina,arrhythmia. Hormone replacement therapy or symptomatic treatment is the common used method of modern medicine,although a certain degree of efficacy,but there are also significant disadvantages. In the treatment of cardiovascular disease in peri-menopausal period,TCM has certain advantages. In this paper,we treat cardiovascular disease in peri-menopausal period from the theory of 'yin deficiency,blood stasis,heat-toxin'and propose the method of 'nourishing yin,promoting blood circulation and detoxification'.

Objective: To evaluate the rationality and practicability of the provincial directory of antibacterial drugs classification management in China. Methods: The directories at the provincial level published after May 2012 were collected from the government websites of health department in different provinces, cities and autonomous regions. The name, number, grading and classification were counted and anzlyzed. According to the relative national standards, the rationality, practicability and existing problems were ana-lyzed, and some revision sugestions were proposed. Results:Up till now, 30 dirctories were issued with the average recording number-varieties of 147. 1(101-194). The average number of unrestricted, restricted and special use level was 56. 4(37-66), 53. 7(34-68) and 37(24-75), respectively. The top 5 was cephalosporins(29. 5), penicillins(24. 8), antifungi drugs(14. 7), quinolones(12. 8) and aminoglycosides(10). Overall, the directories were rational and practicable. However, 29 kinds of antibacterial drugs were with-out registered number of approval, which was not reasonable or practicable. The other problems were inappropriate classification and grading, name writing mistakes, ect. Conclusion:The directories should be revised in time to correct the existing promblems and im-prove the directories.

Dilated cardiomyopathy is a disease which manifests with heart enlargement, myocardial contractile dys-function and arrhythmia. The disease cause is unknown. And the disease prognosis is not good with high fatality rate. There is no specific treatment for dilated cardiomyopathy in modern medicine. Currently, a large amount of clinical researches have been conducted by traditional Chinese medicine (TCM) scholars with relatively satisfied therapeutic effects. This article made a review on the etiology, pathogenesis, treatment method (including syndrome differentiation and treatment, modern application of ancient prescription, self-made prescription, and Chinese patent medicine liq-uid) and TCM treatment progress of dilated cardiomyopathy in order to show that TCM has certain advantages in the treatment of dilated cardiomyopathy.

Aim To investigate the toxicity of isopsor-alen in HepG2 cells and its effects on bile acid, bile acid synthesis and transport. Methods Cell viability was evaluated by MTT assay and bile acid was deter-mined inside HepG2 cells, with exposure to various isopsoralen for 24h. The mRNA transcription of BSEP, MRP2, MRP3, NTCP, OATP2, OSTα, CYP7A1, CYP27 A1 , FXR and PXR were assessed by real-time PCR. Results The cell viability was decreased dose-dependently with isopsoralen in HepG2 cells, and IC50 was 118. 1μmol·L-1 exposure to isopsoralen for 24h. Bile acid inside cells significantly increased with 100 and 400 μmol · L-1 isopsoralen. Isopsoralen caused the down-regulation of MRP2 , MRP3 , CYP7 A1 mRNA at 25 μmol · L-1 . Beside these, the up-regulation of OATP2,OSTα,CYP27A1,FXR,PXR with 100 μmol· L-1 isopsoralen, but there was no significant change of BSEP and NTCP. Conclusion The results show that isopsoralen induces bile acid accumulation and cytotox-icity which may be associated with the down-regulation of MRP2, MRP3 in HepG2 cells.

Objective To investigate the relationship between positive experience and perceived social support of the parents with a cerebral palsy child. Methods 105 parents with a cerebral palsy child who were hospitalized in the Third Affiliated Hospital of Zhengzhou University between November , 2014 and January , 2015 were conveniently selected and investigated about their positive experience and perceived social support with general information questionnaire, positive aspects of caregiving and perceived social support scale. The correlation between the two was analyzed. Results The mean score of the parent′s positive experience was (30.82 ± 5.26); the dimension of self affirmation was (16.71 ± 3.06) and the dimension of life expectation was (14.10 ± 2.85). The scores of the parents′ positive experience were significantly different among gender, education of parents and the age,gender of children. The score of the parents′ positive experience was positively correlated with the total score of perceived social support (r = 0.214, P = 0.029) and the score of other support (r = 0.227, P = 0.020). Conclusions The parents′ positive experience was medium of the high level, which is worth of more attention in order to improve it. The higher perceived social support score is , the more positive experience parents will have.
