Objective The aim of this study is to provide guidance on rehabilitation nursing via observing the effect of comprehensive relaxation training on perioperative psychological stress in patients with coronary intervention treatment. Methods In this study, eighty patients ready to receive coronary intervention were randomly divided into the experimental group and the control group (40 patients in each). The control group were treated with routine percutaneous coronary intervention care, and the experimental group received both comprehensive relaxation training and routine care. The anxiety state and subjective feelings on comprehensive relaxation training in both groups were dynamically investigated via State-Trait Anxiety Inventory questionnaire and subjective feeling questionnaire from pre-operation to 7 days after operation. Results Anxiety levels between two groups showed the similar trend, and there was statistically significance between two groupsin the state anxiety level. The subjective feeling in the experimental group improved. Conclusions The psychological stress in patients receiving coronary intervention surgery maintains at high level form pre-operation to 24h post operation, and comprehensive relaxation training can significantly reduce the level of state anxiety. These patients consider that this simple training shows obvious relaxing effect.

Aim To study the transport of geniposide and geniposide in Zhizi Bopi Decoction in MDCK cell membrane model. Methods The safety concentration of geniposide and Zhizi Bopi Decoction in MDCK cells were determined by MTT assay. Then the MDCK cell membrane model was used to investigate the transport of drugs. Firstly, the effects of time, drug concentra-tion, P-gp inhibitor and EDTA on the absorption and transport of geniposide were studied systematically. Secondly, the differences were compared between the transport of the same concentration of geniposide as single compound and that in Zhizi Bopi Decoction in MDCK cell model. The drug concentration was deter-mined by high performance liquid chromatography ( HPLC) to calculate the apparent permeability coeffi-cient (Papp). Results Geniposide transport in MDCK cell monolayer was time and concentration dependent. P-gp inhibitors had no significant effect on its transport and the transport of geniposide was enhanced by ED-TA. The absorption Papp of different concentrations of geniposide in Zhizi Bopi Decoction were ( 8. 96 ± 0. 35 ) × 10 -7 cm · s-1 , ( 8. 95 ± 0. 38 ) × 10 -7 cm · s-1 and (9. 16 ± 0. 30) × 10 -7 cm·s-1, significantly higher than the absorption Papp of geniposide as single compound(5. 85 ± 0. 44) × 10 -7 cm·s-1, (6. 88 ± 0. 38) × 10 -7 cm·s-1 and (6. 31 ± 0. 19) × 10 -7 cm ·s-1 ( P<0. 05 ) . Conclusion The transport of ge-niposide in MDCK cell membrane model is passive transport and is not affected by P-gp. Geniposide may transport via the paracellular route. The Zhizi Bopi De-coction can increase the absorption of geniposide.

This study is to investigate the sedative and hypnotic effects of a novel compound H1208. The sedative activity of H1208 was investigated by recording the spontaneous locomotor activity of mice. The hypnotic property was evaluated by the latency and duration of sleep (loss of righting reflex) in mice and the effect of hypnotics on sleep pattern of electroencephalogram were studied in conscious, freely moving mice with chronically implanted electrodes. The brain monoamine neurotransmitters levels in mice were measured by high performance liquid chromatography-electrochemical detection. The spontaneous locomotor activity was decreased by 56.7% and 80.2% in H1208 (5 and 25 mg x kg(-1), ip) treated mice, respectively. The loss of righting reflex was directly induced in mice after H1208 (60 mg x kg(-1), ip) administration. The non-rapid eye movement sleep increased significantly by 131% and 259%, respectively, within 3 hours after H1208 (30 and 60 mg x kg(-1), ip) administration. However, the rapid eye movement sleep decreased significantly. The contents of DA in the striatum and cortex and 5-HT in the cortex decreased significantly. These results demonstrated that H1208 has potent sedative and hypnotic effects, which may be closely related to the decreased contents of DA and 5-HT in mouse brain.

Ten dogs were divided into 2 groups and absolute ethanol was injected into the renal artery and its branches respectively. The kidneys injected were resected by stages and examined pathologically. The results showed that coagulative necrosis developed in the renal artery and kidney itself. In the group whose branches of the renal artery were injected there was a clear demarcation line between the necro-tic and the normal areas. The thrombus formed secondary to necrosis might worsen the blockage of the renal artery. The clinical observations on the renal artery injected with absolute ethanol in 15 cases showed that the method of absolute ethanol injection was better than any other methods or drugs for the renal artery. The injection was safe, convenient and more favourable to the prevention of the spread of cancer cells.

Rho/ROCK pathway is a ubiquitous singling pathway in organisms,and is involved in many biological processes. In the brain of Alzheimer′s patients,the activities of Rho and Rho associated coiled coil forming protein kinase(ROCK)are up-regulat?ed,which is accompanied by the elevation of Aβ42 level,and the abnormal change of the morphology and function of neuronal process?es,suggesting that the occurrence and development of Alzheimer′s disease(AD)is associafed with the overexpression and excessive activation of Rho or ROCK. Rho/ROCK2 pathway is considered a target pathway for the prevention and treatment of AD,and Rho or ROCK2 also becomes an important target for AD drug development. Numerous studies have revealed that suppressing the expression or decreasing the activity of Rho or ROCK2 can reduce Aβ42-induced neurotoxicity,protect neurons,and slow down the occurrence and de?velopment of AD. Therefore,specific inhibition of ROCK2 has an important significance for the repair of central nervous system dam?age and the treatment of AD. This article reviews several effects of Rho/ROCK2 pathway on the development of AD.

Objective:To explore the effect of case teaching in clinical nursing teaching and medical ethics ed-ucation in the department of cardiology. Methods: A sample of 75 nurse interns came to practice in November 2014 to April 2015 were allocated to the control group, while 96 nurse interns came in July 2015 to December 2015 were allocated to the experimental group. The interns in control group were taught according to the traditional teach-ing method, and the case teaching method was used in the experimental group. The scores of critical thinking abili-ty and the times of praise were compared between the two groups. Results:Both critical thinking ability and praise of the interns in the experimental group were better than those in the control group ( P<0 . 01 ) . Conclusion:In-troducing the case teaching method to clinical nursing teaching and moral education can improve nurse interns′clin-ical critical thinking ability and stimulate the enthusiasm for learning. Meanwhile, it is beneficial to cultivate nurse interns′medical humanistic spirit and improve the medical humanistic quality.
