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.

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.

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.

BACKGROUND: Routine magnetic resonance imaging(MRI)scans can comparatively show intra-articular soft tissue structures,but there are still some limitations in the diagnosis of intra-articular lesions and injury due to deficiency in contrast of imaging.Enhanced MRI scan has been applied to the liver,brain and other parts,which effectively improves the diagnostic accuracy,but there are few reports on the enhanced scans of knee.OBJECTIVE: To evaluate clinical application value of MRI enhancement pattern in diagnosis of knee injury.METHODS: Totally 21 patients with knee injury(22 knees)were routinely scanned by 0.5T Signa Contour MRI scanner(GE company,USA).Then enhancer was injected into knee joint by the same physician and MRI enhancement pattern was performed in these patients.Film-reading and comparison were completed by two associate chief physicians.RESULTS AND CONCLUSION: Different levels of joint structural damage,such as bone,meniscus,ligaments,and articular cartilage and so on,were found in all patients by routine MRI scan.The extent and scope of its damage had been more clearly displayed by enhanced MRI scan.Meanwhile,misdiagnosis of meniscal injury by routine MRI scan was confirmed by enhanced MRI scan in 2 patients.Some damaged parts that were not found by routine MRI scan were Confirmed by enhanced MRI scan.All these demonstrated that positive rate of knee injury in MRI enhancement pattern was higher than conventional MRI scan.There was significant difference in meniscus injury between two patterns(P = 0.035).MRI enhancement pattern in comparison with conventional MRI can further improve the diagnostic accuracy rate of knee injury.

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.

Objective To explore the inhibitory effects of RNAi targeting survivin to suppress the expression of survivin and to induce the apoptosis of human renal cancer cell line 786-O.Methods The target gene fragments were cloned into pcDNATM 6.2-GW/EmGFPmiR vectors,and then the recombinant eukaryotic expression vectors were transfected into 786-O cells with liposomes.The expression changes in survivin mRNA and protein were detected by RT-PCR and immunohistochemical assay,and the proliferation inhibitory rate (IR) of 786-O cells was detected by M'TT assay.Results The mRNA and protein expressions of survivin in the siRNA group were significantly inhibited by the eukaryotic expression vectors,and it also inhibited significantly the growth and proliferation of 786-O cells.Conclusion Silencing survivin gene by the RNAi technique can not only effectively decrease the expressions of survivin gene and protein,but also inhibit the cell proliferation in 786-O cells.This may provide the experimental evidence for the survivin gene as a target of gene therapy in renal cancer.
