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.

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.

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.

To compare the degree of glycemic excursions by dynamic glucose monitoring in type 2 diabetes in the elderly when their HbA_1c≤6. 5, The mean blood glucose level and hypoglycemia incidence were observed. The amplitude of glycemic excursions revealed by DGMS was significantly lower in insulin glargine group than in mixed insulin group (P<0.05). The incidence of hypoglycemia were lower in glargine group than in mixed insulin group(P<0.05).

Cutaneous wound healing is a complicated multiatep process with numerous mediators that act in a network of activation and inhibition processes. Nonhealing chronic wounds decrease the quality of Life. Recombinant growth factors, currently used in clinic, fail to provide a sustained repair function at the wound due to their inadequate biological availability and transient half-time. Recent attention has focused on gene therapy, which might become a significant treatment modality for those wound healing pathologies refractory to other wound management approaches. This review discusses the potentials and limitations of current genetherapy for the treatment of wounds, current ongoing clinical trials, and possible future directions in this exciting field.

Alginate fiber is prepared by wet spinning method.The preparation process of alginate fiber is:dissolution,filtration,deaeration,figuration,stretching,washing,drying and convoluting.At present,one of thebiodegradable fibers studied the most is alginate fiber.The material,principle and producing technology of alginatefibers are introduced in this article and its application in wound dressings are underlined.
