Acute myeloid leukemia (AML) is a highly heterogenous disease with multiple signaling pathways contributing to its pathogenesis.A key driver of AML is the mutation of FMS-like tyrosine kinase receptor-3 (FLT3) gene.Mutations in FLT3,primarily the FLT3-internal tandem duplication (FLT3-ITD),are associated with decreased progression-free and overall survival.Due to the importance of FLT3-ITD and its pathway in the prognosis of patients with AML,it has stimulated efforts to develop therapeutic inhibitors of FLT3.Although the FLT3 inhibitors show a certain degree of antileukemia activity,their clinical effect has some limitations as a single drug.Now,Quizartinib (AC220) is the potent second generation FLT3 selective inhibitors.Based on the resistance mechanism for FLT3 inhibitom,more and more scholars has been studying the inhibition of FLT3-ITD+ cell lines and primary leukemia cells by AC220 alone and in combination with cytotoxic chemotherapies/protein kinase inhibitors as well.However,the clinical effects of a variety of combination plan remain to be further investigated.

OBJECTIVE: To evaluate the value as well as correlation between blood drug level and blood routine results in patients using cyclospone A (CsA) following renal transplantation via analyzing varies of immunosuppressive agents used in renal transplantation. METHODS: Retrieval-related contents were collected by computer from Chinese Journal Full-Text Database with of "renal transplantation, CsA, and therapeutic drug monitoring". Simultaneously, data of patients who received CsA treatment after renal transplantation in the Department of Laboratory, Liaoning Provincial Electrical Hospital were selected. All the literature was retried and analyzed. RESULTS: A total of 717 patients were included in the final analysis. It demonstrated that 6 sorts of immunosuppressive agents, such as mizoribine, sirolimus, zenapax, mycophenolate, and basiliximab play an important role in immune suppression after organ transplantation. However, there still exist problems need to be further explored. CsA was more suitable for clinical application with lower price and good curative effect, which worked better combined with other immunosuppressive agents. CONCLUSION: A best curative effect of CsA can be achieved by timely adjusting therapeutic regimen under the patient's condition. Meantime, a high efficiency and low toxicity drug with specific tolerance is the ultimate goal of immunosuppressive agents.

Taking the basic theory of Chinese medicine as the instruction, through the bidirectional features of clinical manifestations, the relative etiology and pathology, acupoints and treatments, the bifunctional law in acupuncture theory is discussed. And it is held that after the confirmation of bidirectional symptoms of some diseases or syndromes, acupoints which have special functions in the bifunctional theory of acupuncture with a narrow meaning can be taken as major acupoints. And at the same time, other proper acupoints and flexible treating methods can be selected under the instruction of the bifunctional law of the broad meaning, so as to get the best therapeutic effect.

Embryonic stem(ES) cells are derived from totipotent cells of the early mammalian embryo and are capable of unlimited, undifferentiated proliferation in vitro. The establishment of mouse ES cell lines demonstrated the unmatchable convenience for the study of mouse embryonic development and the particular gene regulation and function. It has been long expected to construct such cell line for human. Here we summarized the development in the construction of human ES cell line, its potential utilization in various fields and the possible ethical dilemmas it brought with were also discussed.

Acquired aplastic anemia(AA) is a disease of bone marrow failure mediated by autoimmune T cells. CD4+CD25+ regulatory T cells, which have immunosuppressive and anergic, belong to a subpopulation of T cells specialized for immune regulation and play important roles in the development of autoimmune T cells. Foxp3 plays a significant role in the development and function of regulatory T cells which have been confirmed by many investigations. In recent years, the relationship between CD4 +CD25 +Foxp3 + regulatory T cells and AA has become a hot spot of research. What’s more, its clinical significance is becoming more and more obvious in AA.

Objective To observe the clinical efficacy of deep needling the points around the ear plus scalp acupuncture in treating neurosensory tinnitus.Method Totally 210 patients with neurosensory tinnitus were randomized into a treatment group and a control group, 105 cases in each group. The treatment group was intervened by deep needling the points around the ear plus scalp acupuncture, while the control group was by conventional acupuncture. The clinical efficacies were compared between the two groups after 3 treatment courses.Result The total effective rate was 82.9% in the treatment group versus 63.8% in the control group, and the difference was statistically significant (P<0.05).Conclusion Deep needling the points around the ear plus scalp acupuncture is an effective method in treating neurosensory tinnitus.

Objective To explore the role of claudin-3, claudin-4 in carcinogenesis and progression of ovarian mucous cystoadenocarcinoma. Methods Immunohistochemical and in situ hybridization method were employed to detect the expression of claudin-3, -4, claudin-4 mRNA in ovary epithelium, mucinous cystadeno-nut, mucinous cystadenoma of borderline, mucous cystadenocarcinoma. Results claudin-3, -4 expression was lowest in ovarian epithelium and mucinous cystadenoma, higher in borderline mucinous cystadenoma, and high-est in ovarian cystadenocarcinoma(P<0.05 ). The expression of claudin-3, -4 in poor differentiated ovarian carcinoma was stronger than that in well- differentiated and moderately differentiated carcinoma (P< 0.05 ),but there was no significant difference between well-differentiated and moderately differentiated carcinoma(P>0.05). Conclusion The overexpvession of claudin-3, -4 is correlated closely with the carcinogenesis and advancement of ovarian mucinous carcinoma, and may have correlation with the differentiated degree of o-varian carcinoma, claudin-3, -4 may become the specific markers of ovarian mucous cystadenocarcinoma.

BACKGROUND:Latest researches suggest that delayed endothelial repair in drug-eluting stents may cause thrombosis and coronary occlusion.Therefore,a novel kind of drug stent,which is characterized by satisfactory anti-proliferative action as well as inhibitive effects on thrombosis,needs to be developed.OBJECTIVE:To summarize the recent research progress and clinical applications of drug-eluting stents (DES) and to seek the direction of new developments.RETRIEVE STRATEGY:The retrieve staffs were the research personnel for this paper.A computer-based online search was conducted in PUBMED for English language publications containing the key words of "drug eluting stents,percutaneous coronary intervention,coronary disease" from January 2002 to April 2007.Relevant data were also searched in international conference reports on the Internet between January 2005 and June 2007.The number of total retrieved Iiteratures was 15.Inclusion criteria:①reports about drug stents;②reports on research progress in the field of drug stents;③reports on the clinical application of drug stents.Exclusion criteria:low relevance and duplicated articles.LITERATURE EVALUATION:There were 264 articles about research and clinical applications of DES.Of those,42 literatures and 5 conference reports with high relevance and timeliness were included in this report.DATA SYNTHESIS:An ideal DES is comprised of a platform,a drug carrier vehicle and a pharmaceutical compound in harmony with each other.Given the ongoing development of DES materials and drugs,more effective DESs are introduced in the clinical practice.Recently,clinical data on DES encourage the interventional cardiologist to use DES in more challenging coronary lesions,such as chronic total occlusions,complex lesions and multivessel lesions.However,concern that DES may be associated with a risk of late thrombotic events arose,suggesting an imbalance between safety and efficacy of DES.Therefore,novel strategies including bioabsorbable stents,and stents coated with pro-healing agents are promising.CONCLUSION:The development of DES is a breakthrough in interventional cardiology that bring great benefit to patients with coronary disease,especially for restenosis and revascularization.Nevertheless,more endeavour will be necessary to create DES with high efficacy as well as low risk.
