Currently,medical ethics education is well popularized,yet not popular among medical students,interns or clinical doctors,for which its formalistic teaching content and mode are to blame.To realize its real educative effects,infiltrating medical ethics into the ideological perception among medical students,interns and clinical doctors,besides horizontal expansion in education popularity,more emphasis should be put to grasping and instructing the essence of medical ethics on a vertical level in order to make the recognition of medical ethics education as common sense among medical professionals.

Objective To observe the curative effect of simvastatin to treat carotid atheroma. Methods 106 patients with carotid atheroma were randomly divided into two groups. The treatment group( n=56) was given orally 20 micro-gram of simvastatin every night, while the matched control group( n = 50) was given 100 microgram of aspirin enteric-coated everyday for 4 months. Results After four months of follow-up, the carotid artery inner-intermediate thickness and the speckle's size,examined by the color Doppler, were obviously decreased ( P 0.05). Conclusion Simvastatin can obviously ameliorate the carotid atheroma. It can be served as one of the normal selections for treating the carotid atheroma.

Objective To explore the protective effects of Salvia miltiorrhiza and Carthamus tinctorius active ingredients in different compatibility on cerebral ischemia-reperfusion injury in rats. Methods Adult male Sprague-Dawley (SD) rats were selected to establish a cerebral ischemia-reperfusion (I/R) injury model by middle cerebral artery occlusion (MCAO) method. The rats were randomly divided into sham operation group, model group, and positive control group (Danhong Injection 2 mL/kg); And orthogonal test method L9(34) was adopted to compose nine compatibility groups from main active ingredients of S. miltiorrhiza and C. tinctorius (trashinol, salvianolic acid A, salvianolic acid B, and HYSA). Rats were tail iv administrated once daily for continuous 3 d. Score neurological deficit was evaluated after 3 d; qRT-PCR was used to detect mRNA expression of glucose regulated protein 78 (GRP-78), nuclear factor-κB (NF-κB), C/EBP homologous protein (CHOP), tumor necrosis factor-α (TNF-α), and interleukin-6 (IL-6); HE staining was used to detect the pathological changes of cerebral cortex, and the expression of NF-κB p65 protein in cerebral cortex was detected by immunohistochemistry. Results Compared to the model group, Danhong Injection group and orthogonal compatibility nine groups significantly reduced the neurological deficit scores of rats with cerebral ischemia-reperfusion; increased the mRNA expression of GRP-78 in the cerebral cortex; decrease the mRNA expression of NF-κB, CHOP, TNF-α, and IL-6, and decrease the protein expression of NF-κB p65 in the cerebral cortex. The results also showed that the protective effects of the 4th group (danshensu 30 mg/kg, salvianolic acid A 2.5 mg/kg, salvianolic acid B 16 mg/kg, and HYSA 8 mg/kg), 6th group (trashinol 30 mg/kg, salvianolic acid A 10 mg/kg, salvianolic acid B 8 mg/kg, and HYSA 4 mg/kg) in the 9th group were more significant for cerebral ischemia reperfusion injury in rats. Conclusion The active components of S. miltiorrhiza and C. tinctorius can play a good protective role in endoplasmic reticulum stress and inflammation in rats with cerebral ischemia reperfusion injury.

The traditional Chinese medicine and somatostatin are very important.

OBJECTIVE:To observe clinical efficacy and safety of paclitaxel or 5-fluorouracil combined with nadaplatin in the treatment of advanced nasopharyngeal carcinoma(NPC). METHODS:42 patients with advanced NPC were randomly divided into observation group and control group(n=21). 2 groups of patients were treated with radiotherapy. Observation group received che-motherapy of paclitaxel(135 mg/m2,d1)and nedaplatin(80 mg/m2,d 2-4);control group received chemotherapy of 5-fluoroura-cil(500 mg/m2,d1-5)and nedaplatin(80 mg/m2,d1-3);a treatment course lasted for 3 weeks,and both groups received 2 courses of treatment. Clinical efficacy, survival rate and ADR were observed in 2 groups. RESULTS:The overall response rate was 95.2%in observation group and 90.5% in control group,with no significant difference between 2 groups (P>0.05). The 3-year overall survival rate and progression-free survival rate were 81.0% and 71.4% in observation group and 76.2% and 66.6% in control group,with no significant difference(P>0.05). The incidence of nausea and vomiting in observation group were lower than in con-trol group,while the incidence of oral mucosa inflammation was higher than control group,with statistical significance(P<0.05). CONCLUSIONS:The chemoradiotherapy of paclitaxel or 5-fluorouracil combined with nadaplatin have similar therapeutic efficacy for advanced NPC. ADR by chemoradiotherapy should be monitored closely and treated timely.

Objective To investigate the Shenmai injection for the inhibition of hepatic and renal toxicity and leukocyte disorder during chemoradiotherapy in the women with advanced breast cancer. Methods 58 cases of female breast cancer patients with stage Ⅳ were selected and randomly divided into 2 groups, 29 cases of each group, and patients were treated with 5-hydroxytryptamine (5-HT3) receptor antagonists and white blood cell growth hormone and other conventional therapy, the control group received gemcitabine plus cisplatin chemotherapy, 28d for 1 cycles, the treatment group received more with Shenmai injection, interval was 15d, 2 groups were treated for 3 cycles. Levels of peripheral blood T lymphocyte subsets, cytokine levels and liver and kidney function, quality of life and clinical efficacy were compared. Results Compared with before treatment, levels of CD3+, CD4+ and CD4+/CD8+ in control group decreased (P<0.05), levels of CD3+, CD4+ and CD4+/CD8+ in treatment group increased (P<0.05), levels of CD8+ decreased(P<0.05), levels of IFN-γ, IL-2 and TNF-α increased(P<0.05), levels of IL-6 decreased(P<0.05), scores of KPS increased(P<0.05), scores of FACT-B decreased(P<0.05), levels of ALT, AST, BUN increased(P<0.05), and levels of CCr, WBC counts decreased(P<0.05), and compared with the control group, levels of CD3+ , CD4+ and CD4+/CD8+ in the treatment group were higher(P<0.05), levels of CD8+ were lower(P<0.05), levels of IFN-γ, IL-2 and TNF-α were higher(P<0.05), levels of IL-6 were lower(P<0.05), and the total efficiency was higher(P<0.05), levels of ALT, AST, BUN were lower (P<0.05), and levels of CCr, WBC counts were higher (P<0.05).

Objective To identify the influencing factors for pediatric nursese' reporting of adverse events at 3A hospitals in Beijing. Methods Adopting the random sampling of ten 3A hospitals with pediatric wards in Beijing and conducting an questionnaire survey of some nurses in those hospitals. Results The possibility of adverse events reporting increased with the awareness of adverse events which was related with their severity. Except for title, educational background, length of service, position and past experiences were not associated with the barriers. The major perceived barrier was fear of colleague relationship brokenup and some other undesirable consequence. Conclusions Better training of awareness of adverse events and changes of the punitive culture by the roots as well as some regulation or policy were the major solutions to improve incident reporting.
