Application of imatinib has made a lot of chronic myeloid leukemia (CML) patients longterm survival,but the CML BCR/ABL1 kinase domain mutations (KDM) will result in drug resistance of imatinib.There are many KDM types.The different types appear randomly.The leukemic clone with different KDM characteristics has a certain evolution.In the period of imatinib treatment,a higher degree of drug resistance mutations in cells likely to develop as the dominant clone.It is suggested that the treatment of imatinib-resistant CML in addition to efforts to develop next-generation tyrosine kinase inhibitors outside,but also consider the use of traditional medicine to help cure.

Polymerase chain reaction (PCR) technique for the diagnosis of hematological disease brought about revolutionary progress. It has become indispensable and basic technology for genotyping of acute and chronic leukemia and diagnosis of myeloproliferative disorders, thalassemia, hemophilia and other genetic diseases. Based on the PCR technology, multiple nested-PCR, real-time fluorescence quantitative PCR (Q-PCR), denaturing high pressure liquid chromatography (DHPLC), capillary electrophoresis, the molecular hybridization and directly sequencing technique have been developed. The multip]e nested-PCR can be used to examine a variety of leukemia genes and confirm the type of leukemia. The application of Q-PCR has effectively solved the problem of pollution of the PCR and it can be used to monitor minimal residual disease of leukemia. Capillary electrophoresis is more suitable for gene fragment length change. DHPLC can be applied for high-throughput screening of gene mutation. Sequencing is a reliable method and it has been used for routine diagnosis.

Immunophenotyping with flow cytometry can clearly identify multiple myeloma cells and monitor minimal residual disease by using the characteristic of light chain restriction in plasma cells and some cell surface markers( eg CD138, CD38, CD56, CD117 ). This technology may provide important evidence in the diagnosis of multiple myeloma.

Thirty-four patients with acne vulgaris were treated with pricking and ear-pressure. Acupoints were Baihui (GV 20), Dazhui (GV 14), Taodao (GV 13), Shenzhu (GV 12), Shendao (GV 11), Lingtai (GV 10), Feishu (BL 13), and Sanyinjiao (SP 6), for priking. Lung (MA-IC1), Stomach (MA-IC),Endocrine (MA-IC3), Subcortex (MA-AT1), EarShenmen (MA-TF1) and Cheek (MA-L) were applied for ear-pressure. After 4 courses' treatments, 33 cases obtained effectiveness and 1 case ineffectiveness.

With the fierce competition of higher education market,the public university and college face the pressure from mana-gement toward economic operation.This article tries to make some study on what the economic operation innovation of the public higher education institutions is,to make a synopsis analysis on disadvantageous factors and advantageous factors,and to put forward some suggestions on its promising system.

OBJECTIVEThis study aims to compare the fracture resistance of teeth restored with different post and core systems by cyclic loading test and to predict long-term effects.

METHODSA total of 15 recently extracted mandibular premolars without crowns were endodontically treated. The teeth were randomly divided into three groups with five teeth in each group. Group A, teeth restored with cast metal post and core. Group B, teeth with fiber post and resin core. Group C, teeth with resin filling. All of the teeth were restored with full-cast metal crowns. The specimens were exposed to 300,000 cyclic loadings in a cyclic loading machine and 1,000 thermal cycles between 5 and 55 °C. All of the samples were loaded in AG-IS mechanical testing machine with a compressive load until fracture occurred. The fracture load and the fracture mode of each tooth were recorded.

RESULTSThe fracture resistance in group B and C were higher than that of the cast metal post and core restoration (P < 0.05). Repairable fractures were observed in group B and C, whereas unrestorable and catastrophic fractures were found in group A.

CONCLUSIONFiber post and resin filling is a good choice to restore endodontically treated teeth.

Objective To observe the efficacy of rosiglitazone treatment in impaired glucose tolerance (IGT) with hyperinsulinemia. Methods 56 IGT patients were divided into two groups randomly:control group (28 cases) and rosiglitazone group (28 cases). Improving life style were given to control group,while improving life style and rosiglitazone (4mg/d) were given to rosiglitazone group for 12 weeks. The body mass index (BMI),fasting and postprandial plasma glucose,insulin and insulin sensitivity index (ISI) were observed. Results In control group the fasting and postprandial plasma glucose and insulin showed no difference between pre-and post-treatment (P>0.05).The levels of the fasting and postprandial plasma glucose and insulin dropped obviously in rosiglitazone group compared to both the baseline levels and the levels of control group at 12 weeks of treatment(P<0.05). The BMI and body weight dropped obviously in control group at 12 weeks of treatment (all P<0.05),but showed no difference in rosiglitazone group (P>0.05). The ISI increased markedly in rosiglitazone group (P<0.05),but showed no difference in control group (P>0.05). Conclusions The rosiglitazone treatment increases insulin sensitivity obviously,improves first-phase insulin secretion,and postpones the progression to T2DM from impaired glucose tolerance in patients with IGT

Objective To compare the efficacy and incidence of complications of stenting alone and intratumoral injection of recombinant human adenovirus p53 combined with stent implantation in the treatment of advanced esophageal cancer patients.Methods 2 4 cases with advanced esophageal cancer,who could only eat semi liquid,liquid food or could not eat,were randomly divided into control group(A group) and treatment group (B group).12 cases in A group were treated with esophageal stent implantation,12 cases in B group were given endoscopic intratumor injection of recombinant human adenovirus p53 combined with food tract stent implantation.Results The rate of improvement of dysphasia had no significant difference in survival period:the treatment group survival time of 3.2-38 months,mean (27.0 ± 2.3) months,while the control group survival time of 2.8-27months,an average of (14.7 ± 8.0) months,the difference between the two groups was significant (t =3.521,P ＜ 0.05).The incidence rate of restenosis in treatrnent group was 8.3％,that in control group was 41.7％.There was significant difference (x2 =7.532,P ＜0.05).Conclusion Endoscopic intratumor injection of recombinant human adenovirus p53 combined with esophageal stent implantation in the treatment of advanced esophageal carcinoma can prolong the survival time of patients with esophageal stent implantation,and to reduce the incidence of restenosis.

In this paper, the importance of using advanced medical equipment to check treatment was ana-lyzed, and then pointed out that nowadays there were the following problems: the medical staff had excessive de-pendence on medical equipment; medical equipment inspection treatment of irrationality; medical equipment in-spection treatment with humanity was not enough; medical equipment management of dereliction of duty. Put for-ward to strengthen medical personnel professional moral education;to strengthen the medical students' ethical edu-cation;regular hospital manage concept;improve the cognitive level of medical staff of medical equipment.
