SALL4 gene is closely related to body malformations related diseases, embryonic stem cell development, and hematopoietic malignancies. SALL4 can activate hematopoietic stem cell through Wnt signaling pathways, and promote continued proliferation of leukemia stem cells, leading to leukemia. In-depth study of SALL4 gene and its protein function will help clarify the pathogenesis of leukemia, providing a new target for the treatment of leukemia.

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 The aim of this study was to demonstrate the effectiveness of the procedure for the prolapse and haemorrhoids in management of haemorrhodis.Methods Analyze the data of sixty-two consecutive patients with third or fourth degree hameorrhoids treated by the procedure for the prolapse and haemorrhoids.Results The median surgical time was 15 minutes,the median postoperative hospital stay was 2.3 days,median time to retum to normal activity was 6.8 days.Five patients need postoperative analgesic,on postoperative bleeding,eighteen patients had acute urinary retention.Fifty-six(90.32%) of the patinets had been followed up to 6 weeks,fifty patients were satisfied with the results of the procedure.Conclusion The procedure for the prolapse and haemorrhoids is a safe and effective treatment for severe haemorrhoids and with the advantages of shorter time of operation and inpatient stay,earlier return to normal activity.

Hospitalization expenses constitute the main part of the compensation of medical insurance.The aim of this paper is to analyze the variation of medical expenses of hospitalized patients with medical insurance in different modes of accounting,find the influencing factors in accounting quotas on hospitalization expenses,and set up a scientific and reasonable mode of accounting with a full consideration of the huge demands of medical resources.

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.

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). After treatment, the efficacy of treatment group was higher than that of control group(Z=-2.142,P=0.032<0.05). Conclusion Shenmai injection can improve the efficacy of radiotherapy and chemotherapy in patients with advanced breast cancer, and it can effectively inhibit the liver and kidney damage and leukocyte disorder.

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.
