AIMTo observe the effect of rhubarb ethanol-extract on hyperlipidemia and liver fatty in rabbits.

METHODSThirty healthy male white rabbits were divided randomly into five groups, six rabbits in each group. The rabbits in control group were fed with common forage. The rabbits in model group were fed with high lipid forage. The rabbits in three different rhubarb groups were fed with high lipid forage and treated with different level rhubarb ethanol-extract (REE). In the process of experiment, periodically measured serology index of the rabbits and observed common physiology index. The rabbits were killed at the end of tenth week, liver fatty degeneration degree and liver coefficient were measured and compared.

RESULTSREE could decrease serum total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), and increase serum high density lipoprotein cholesterol (HDL-C), and reduce liver fatty de generation and protect liver cell function. And the dose-effect relation was showed among different dose REE groups.

CONCLUSIONREE can significantly reduce blood lipid, prevent and treat hyperlipidemia and liver fatty.

Objectives? To explore the effects of applying growth mentor program in the training of new nurses. Methods? By convenient sampling, the newly recruited nurses who signed official employment contract with the First Affiliated Hospital of Xi'an Jiaotong University were selected as subject. A total of 756 nurses who enrolled from 2008 to 2012 were put into the control group and 812 nurses enrolled from 2013 to 2017 were in the observation group. The control group received routine training while the observation group received the training of the growth mentor program. The two groups was compared in the resignation rate, annual assessment scores, and patients' satisfaction. Results? The differences in resignation rate between the observation group (0.37%) and the control group (1.06%) were statistical significant (P＜0.01). The annual assessment scores of the observation group (88.63±2.17) and patients' satisfaction (96.78±1.76) were all higher than the control group with statistical significance (P＜ 0.01). Conclusions? The establishment and implementation of the new nurses' growth mentor program can significantly reduce the nurses' resignation rate, improve the nurses' professional skills and patients' satisfaction, therefore the program should be widely applied in new nurses' training in hospitals.

Objective To observe the improvement of motor dysfunction and serum levels of C-reactive protein(CRP),blood glucose and blood lipid in post-stroke patients treated with scalp acupuncture at different needle retention time.Methods A total of 120 patients with motor dysfunction after stroke were randomly divided into control group,observation group 1 and observation group 2,with 40 cases in each group.The patients in the 3 groups were treated with scalp acupuncture,body acupuncture and routine rehabilitation exercise,once a day and 6 times a week,lasting for 2 weeks.The control group was given scalp acupuncture with retaining of needles for 30 minutes,the observation group 1 was given scalp acupuncture with retaining of needles for one hour,and the observation group 2 was given scalp acupuncture with retaining of needles for 2 hours.Before and after treatment,the 3 groups were observed in the changes of the scale scores of National Institutes of Health Stroke Scale(NIHSS),Fugl-Meyer Assessment(FM A),Berg Balance Scale(BBS)and modified Barthel Index(MBI),and the levels of laboratory indicators of peripheral blood CRP,fasting plasma glucose(FPG),total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C)and low-density lipoprotein cholesterol(LDL-C).After treatment,the clinical safety of the three groups was evaluated.Results(1)After treatment,the scale scores of NIHSS in the three groups were lower(P＜0.01)and the scale scores FMA,BBS and MBI were higher than those before treatment(P＜0.05 or P＜0.01).The comparison of post-treatment scale scores showed that the differences among the three groups were statistically significant(P＜0.01).The intergroup comparison showed that the decrease of NIHSS score and the increase of FMA,BBS and MBI scores in the observation group 2 were significantly superior to those in the control group and the observation group 1(P＜0.01);the improvement of FMA score in the observation group 1 was significantly superior to that in the control group(P＜0.01),while the improvement of NIHSS,BBS and MBI scores tended to be superior to that in the control group without statistically significant differences(P＞0.05).The results indicated that the curative effect of scalp acupuncture plus exercise regimen was positively correlated with the duration of needle retention for scalp acupuncture.(2)After treatment,the laboratory indicator levels of CRP and FPG in the peripheral blood of the three groups,the levels of TG and LDL-C in the two observation groups and the level of HDL-C in the observation group 2 were improved compared with those before treatment(P＜0.05 or P＜0.01).Statistically significant differences were presented in the post-treatment levels of CRP and TG in peripheral blood among the three groups(P＜0.05 or P＜0.01).The intergroup comparison showed that the improvement of CRP and TG levels in the observation group 2 was significantly superior to that in the control group,and the improvement of CRP level in the observation group 2 was significantly superior to that in the observation group 1,the differences being statistically significant(P＜0.05 or P＜0.01).The TC level in the three groups after treatment did not differ from that before treatment,and there was no significant difference in TC level after treatment among the three groups either(P＞0.05).(3)During the treatment,no adverse reactions such as fainting,needle breaking and hematoma occurred in the three groups,the vital signs of the patients were stable,and there were no obvious abnormal changes in pulse,blood pressure and respiratory rate.Conclusion Scalp acupuncture can effectively improve the motor function of post-stroke patients in a pasitive time-effect relationship with the needle retention,and better the curative effect can be achieved by retaining of the needle for 2 h.

The difficulty to eradicate the HIV-1, off-target effects together with the rapid emergence of multidrug-resistant strains have created an urgent need for more potent and less toxic therapies against other targets of HIV virus. From the point of view of medicinal chemistry, we summarizes and discusses current endeavours towards the discovery and development of novel inhibitors with various scaffolds or distinct mechanisms of action, and also provides examples illustrating new methodologies in medicinal chemistry that contribute to the identification of novel antiretroviral agents.
