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 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.

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 assess examinational methods of Multi-slice CT(MSCT)in diagnosis of palatine lesions. Methods 28 cases were performed MSCT examination with the conventional method,extending -tongue method,colliding-tongue method and pronouncing method. All images were reconstructed by means of multiplana reconstruction (MPR) and CT virtual endoscope (CTVE). Results Correct diagnosis were obtained through the complementarity of the methods. Conclusion Reasonable examination methods of MSCT is apt to display palatine lesions.

The apoptosis was observed under a fluoroscope when the tested tumor cells were treated with the supernatant derived from the liquid culture of an actinomyces strain AK 11, which had showed cell toxicity by means of MTT assay, and was further confirmed by the correspondent band of ”DNA ladder” in the agarose gel electrophoresis. In a bioassay employed nude mouse, the pure compound produced by the strain AK 11 showed tumor inhibition in rates of 52.01% and 33.64% corresponding to the dosages of 0.016 ?g?kg -1 and 0.008 ?g?kg -1 ip, respectively. According to the indexes IC 50 of human hepatocarcinoma SMMC7721 and stomach cancer MGC 803 cells, it was estimated that the inhibition effect of the pure compound was slightly stronger than that of Adriamycin. The results showed high antitumor effect of the tested compound from the strain AK 11. When the cells were treated with AK 11, it was found by flow cytometry analysis that cell division was ceased at S phase due to the DNA synthesis block .

Objective To investigate the clinical and imaging features of Foot-Yangming meridian-muscle syndrome of knee osteoarthritis(KOA) so as to promote the normalization and standardization of the meridian-muscle therapies. Methods A total of 31 KOA cases (involving 31 knees) of Foot-Yangming meridian-muscle syndrome were included into the study group , and 31 healthy volunteers (involving 31 knees) served as the control group. A retrospective research of patellofemoral relationship was carried out based on the clinical and imaging features. Results The differences of Insall index and patella index between the study group and control group were insignificant(P> 0 . 05), but the differences of patellofemoral index , patellofemoral congruence angle, and external patellar angle between the study group and control group were significant(P<0.01). Conclusion The patellofemoral relationship disorder is one of main lesions in Foot-Yangming meridian-muscle syndrome of KOA.

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.
