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.

CONCLUSIONS:Box-behnken response surface method is reasonable and feasible for the optimization of the processing technology for A. lancea stir-baking with bran.

Oncogenesis is a sophisticated process which is polygenic , multi-stage,and multi-step.Livin as an apoptosis inhibi-ting factor , is one of the members of apoptosis inhibiting factor family , it expresses highly in many tumor tissues , and is closely related to the occurrence and development of urological tumor .Tumor growth can be inhibited by interfering the expression of Livin in tumor tis-sue,which will reduce the resistance to apoptosis and increase the rate of cell apoptosis .In recent years , more and more attention was paid to the studies of Livin on gene targeting therapy .Further research of Livin might provide new ideas for the early diagnosis , clinical treatment and evaluation of prognosis of tumor .

Objective: To compare the safety and efifcacy of rivaroxaban and warfarin for treating the patients with left ventricular thrombus. Methods: A total of 31 patients with left ventricular thrombus were studied, the patients were randomly divided into 2 groups:Warfarin group, n=16, the patients initially received oral warfarin and low molecular weight heparin at (2.5-3) mg/day, when the INR value reached 2.0-3.0, heparin was stopped and warfarin was continued, the INR value was monitored every 3 days for 3 times, when INR value was stably kept at 2.0-3.0, it was then monitored for every 2 weeks. Rivaroxaban group,n=15, the patients received oral rivaroxaban at 10 mg twice a day. All patients were followed-up for 3 months, the thrombus remission time, new onset of thrombosis, embolism and bleeding events during treatment period were compared between 2 groups. Results: The patients’ age, gender, complication, size of thrombus and medication were similar between 2 groups. Compared with Warfarin group, Rivaroxaban group had the shorter thrombus remission time, (60.00±5.50)d vs (71.00±8.50) d,P<0.01, while the new onset of thrombosis and embolism events as cerebral embolism and systemic embolism were similar between 2 groups, Warfarin group had slightly higher bleeding events, allP>0.05. Conclusion: Rivaroxaban had better effect than warfarin for treating the patients with left ventricular thrombus without increasing the risk of bleeding.

Objective To evaluate the value of coronary arteriongraphy(CAG)in diagnosing angina.Methods 219 patients with angina in clinical analysis were selected and divided into 2 groups:the stable angina(SA)group and unstable angina(UA)group.They all were accepted CAG first time.Then analysis were carried out between clinical diagnosis and results of CAG.Results The total positive rate of CAG in diagnosing angina is 58.90%.The positive rate of SA group(56.52%)shows no significant difference with that of UA group(60.00%).Single vessel lesion and multiple vessels lesion of SA group have little difference,however,the main coronary artery lesions of UA group is single vessel.Conclusions CAG is extremely important in diagnosing angina,but it has its own limit.Experience and new technique should be applied to retrieve locatization of CAG.
