1.Chronic myeloid leukemia BCR/ABL1 mutation clonal evolution and treatment strategies
Chinese Journal of Laboratory Medicine 2012;35(1):2-5
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.

4.Application of PCR derived technology for diagnosis of hematological disease
Chinese Journal of Laboratory Medicine 2009;32(1):6-9
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.
5.Application of bone marrow cell immunophenotyping analysis in diagnosing and monitoring of multiple myeloma
Chinese Journal of Laboratory Medicine 2011;34(1):2-4
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.
6.In vitro analysis of the effect of cyclic loading on the fracture resistance of teeth restored with different post and core systems.
West China Journal of Stomatology 2015;33(2):206-208
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.

7.Therapeutic effect of rosiglitazone on impaired glucose tolerance combined with hyperinsulinemia
Chinese Journal of Diabetes 2008;16(12):705-707
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

Ophthalmology in China 2006;0(06):-
Objective To evaluate the effect on reliability with different sample amount when human corneal endothelial morpho- logic parameters estimated using center by center method analysis.Design Clinical study.Participants Thirty central corneal endothe- lium photo-micrographs for the same eye. Methods Noncontact specular photomicrographs were obtained.Each photo-micrograph was analyzed with center by center method and was analyzed for 9 times by pointing different amount cells,from 10 to 90.Compare the di- versity of corneal endothelial morphometric parameters between different groups. Main Outcome Measures Corneal emtothelium den- sity,coefficient of variation.Results The coefficient of variation decreased and then kept to a same level when sample cell amount were added from 10 to 90.With the sample cell amounts varied from 10,20,30,40,50 to 90,the coefficient of variation was changed from 9.5,6.3,4.6,4.4.,4.3 to 3.8.Corneal endothelium density had significant difference between the first two groups of 10 and 20 cells with the other groups(P

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.
10.Effect of Protamine Coated PLA Nanocapsule on the Immune Function of Murine BMDCs In Vitro
Acta Medicinae Universitatis Scientiae et Technologiae Huazhong 2016;45(3):298-301
Objective To investigate the effect of protamine(PS)coated polylactic acid(PLA)nanocapsule on the immune response of murine bone marrow-derived dendritic cells(BMDCs).Methods PLA nanocapsules were prepared by W1/O/W2 method.Protamine was used to modify the surface of PLA nanocapsule that encapsulated ovalbumin(OVA),a model anti-gen.The prepared OVA/PLA/PS nanocapsules were used to stimulate BMDCs.Flow cytometry was used to analyze the ex-pression of surface molecules CD80,CD83,CD86,MHCⅠ,and MHC Ⅱ,and the uptake of nanocapsule.The levels of IL-12 p70 secreted by BMDCs were detected by ELISA.Results OVA/PLA/PS nanocapsules could significantly up-regulate the expres-sion of CD80,CD83,MHCⅠ,and MHC Ⅱ in BMDCs,and increase the secretion of IL-12 p70 by BMDCs.Furthermore,OVA/PLA/PS nanocapsules could enhance the uptake efficiency of OVA by BMDCs.Conclusion OVA/PLA/PS nanocapsule can en-hance the immune response of BMDCs,and may become a good drug delivery carrier.
