Through discussing the traditional medical ethics culture and medical ethics,this paper pointed out the main problems in the teaching practice of medical ethics:it did not well handle the relationship between the inheritance of traditional culture and the absorption of foreign culture;it emphasized too much on the learning of analysis methods and tools of ethical problems but ignored the cultivation of personality and morality;the teaching curriculum of medical ethics is unreasonable.This paper discussed the similarities and differences between medical ethics and traditional ethics culture,gasped the common essence of ethics,and put forward to better improve the teaching of medical ethics through the construction of basic theory system,the settings and perfection of curriculum system,the construction and improvement of the curriculum evaluation system,and the inheritance of traditional medical ethics cultural.

To explore the origin and prevention of myopia from disfunction of internal organs and obsrtuction of channels.According to the research of ancient literature on relationship between internal organs/channels and myopia,and in the combination with research on neuroelectrophysiology,hemorheology molecular biology and clinic study,the feasibility of treatment on myopia from dysfunction of internal organs and obstruction of channels were analyzed.Dysfunction of internal organs and obstruction of channels played an increasingly important role in the occurring and developing of myopia.In the treatment of myopia,the role of internal organs and channels must be emphasized.

Objective To study the effect of aspirin on cell proliferation of human gastric cancer cell line SGC-7901 and the probab le mechanism involved. Methods Using MTT method, flow cytometr y (FCM),~~~3 H-TdR incorporation a nd electron microscopy, the effect of aspirin on the SGC-7901 of proliferation and related mechanism were studied. Results Results showed that th e growth of SGC -7901 was inhibited by aspirin. The inhibitory rates for growth of SGC-7901 we re positively correlated with the concentration and duration of aspirin in the m edia. ASA could inhibit DNA syntheses. Sub-G_1 pe ak was detected by FCM, and the rate of apoptosis was between 7.8% and (34.4)% . The cell ratios o f S and G_2/M increased, whereas the cell ratio of G_0/G_1 phase decreased (after) treatment and was in a dose-dependent manner. The SGC-7901 cell line exhibited some mor p hologic features of apoptosis, including cell shrinkage, nuclear condensation, D NA fragmentation, and formation of apoptotic bodies under electron microscopy. Conclusions Aspirin inhibited the growth of human gastric cancer ce ll line SGC-7901. The effects of aspirin on the phase of cell cycle and inducing apoptosis may be partially explained as the cytotoxic effects of aspirin.

[Objective] To investigate the mechanism of Dachengqi Decoction (DCD) in treating systemic inflammatory response syndrome ( SIRS). [ Methods ] Mouse models induced by zymosan A were administered with DCD orally. Serum endotoxin level was detected by limulus assay and TNF-? and IL-6 levels by radioimmunoassay 6, 12 and 24 hours after medication. [Results] Serum levels of endotoxin, TNF-? and IL-6 were increased in SIRS mice. After treatment with DCD, serum endotoxin level was decreased at the 6th and 12th hour ( P

The porcine reproductive and respiratory syndrome virus (PRRSV) can cause reproductive barriers in breeding pigs and respiratory symptoms in piglets. In this review, we summarize research progress of the infection and replication mechanisms of the PRRSV. We also review the virulence determinants of the PRRSV. All these fundamental studies are important for the control and elimination of the PRRSV.

Hypertensive renal damage is based on the extent and duration of hypertension, renal damage caused by varying severity. Hypertensive renal damage due to various causes imbalance of vascular active substances, renal arteriosclerosis, so that the abnormal renal hemodynamic, renal ischemia, low specific gravity of urine, low osmotic pressure and urine. The rapidly increasing incidence of hypertensive renal damage has become one of the most important reasons of end stage renal disease (ESRD). Effective treatment of hypertension is limited by poor compliance and significant adverse reaction of antihypertensive drugs. Therefore, some patients have turned to Chinese medicine (CM), hoping that such treatments might improve the efficiency. The author reviews relevant theory and the latest researches, on the basis of combining diseases and syndrome, discusses state and achievement of hypertensive renal damage with Chinese herbal medicines from fundamental and clinical research and action mechanism from standpoints of Chinese herbal compound and herbal effective chemical composition to take future research for important reference.

Objective To observe the influence of the insulation blanket applied in general anesthesia on the incidence of postoperative delirium.Methods 60 patients with elective laparoscopic cholecystectomy under generalanesthesia with ASA of grade Ⅰ-Ⅱ were selected.According to the random number table,the patients were divided into group A(without insulation blanket)and group B (with insulation blanket),each group in 30cases.The dosage and drug batch number of anesthetic drugs were same.Evaluated each patient using the confusion assessment method-chinese revised (CAM-CR).Recorded the number of cases of delirium for each group when 24 hours,48 hours, 72 hours after operation.Results The incidence of postoperative delirium in group A was 6.7%,which in group B was 0.0%.The incidence of postoperative delirium of group B was lower than group A (P <0.05 ).Conclusion Using insulation blanket to protect body temperature in perioperative operation can reduce the incidence of postopera-tive delirium in perioperative operation.

Objective To evaluate the results of surgical treatment for duodenal gastrointestinal stromal tumor (GIST).Methods Between January 2000 and January 2013,33 patients underwent surgical resection of duodenal GIST in Peking University Cancer Hospital,including local resection and pancreatoduodenectomy.Clinical data,surgical outcome and prognosis were reviewed.Results The median survival time is 94 months (range:55-132 months).The 1,3,5-year survival rates are 97％,89％ and 80％,respectively.The 5 year survival rate of patients after pancreatoduodenectomy and local resection is 78％ and 83％,respectively (P =0.091).It shows that tumor size and mitotic count and Fletcher classification influence overall survival.Conclusions When fulfiling proper safe margins,local resection is a reliable and curative option for most duodenal GISTs.

Objective To identify the property and implications of dendritic cells of peripheral blood monocytes (PBMC) in patients with persistent HBV infection. Methods The PBMC from 18 patients with persistent HBV infection and 10 healthy subjects were incubated and induced into mature dendritic cells (DC) in the completed medium containing GM CSF、IL 4、FLt3 L and TNF ? cytokines. The flow cytometric analysis was employed to detect the expression of surface markers on DC. ELISA test was used to determine the level of interleukin 12 (IL 12) and IL 10 cytokines produced by DCs. The stimulatory capacity of DC were also determined in allogenic mixed leukocyte reaction (MLR). Results A typical morphology of DCs was observed when the PBMCs from healthy subjects and HBV infected patients were induced for 6 7 day in vitro incubation, but there were some significant differences of DCs as follows: (1) the proliferation ability and number of DCs significantly decreased, in particular, the expression levels of HLA DR,CD80(B7 1),CD86(B7 2) and CD1? on DC surface were simultaneously much lower in patients compared to healthy subjects ( P
