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.

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.

Allogeneic hematopoietic stem cell transplantation (allo-HSCT) is a highly successful treatment for hematological malignancies,severe congenital immunodeficiencies and some other diseases.Approximate 50 ％ of the disease-free survival patients suffered from long-lasting severe cognitive impairment after allo-HSCT.Pathological evidences showed parenchymal lymphocytic inflammation,microglia activation,and mild cerebral angiitis-like changes in allogeneic transplanted animals and patients' autopsy.Pay much importance attention to the pathological changes of central nervous system and its impact on cognitive function and take suitable measures would help the patients to achieve a state of complete physical mental and social well-being.

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.

Objective To investigate the changes of the level of oxidative stress and cell apoptosis of secondary brain injury after traumatic brain injury,and the influence of brain-derived neutrophic factor on these parameters in rats,as well as its potential mechanisms.Methods A total 84 adult and healthy male rats was divided randomly into 2 groups:control (n =42) and traumatic brain injury (TBI) groups (n =42).The brain-derived neurotrophic factor (BDNF) group was induced using improved Feeney method and was received abdominal injections of BDNF (0.5 μg/μl) immediately after injury,the control group were received abdominal injections with the same dose sodium chloride injection immediately after injury and repeat one time everyday until the rats was killed.Each group was divided into seven subgroups by sacrificed time after injury,those are 1 h,3 h,6 h,12 h,24 h,3 d,and7 d,each subgroup got6 rats.Each subgroup was randomly selected three rats after being killed.The water content,superoxide dismutase (SOD),malonic aldehyde (MDA),and glutathione (GSH) of rats were measured contusion peri tissues brain tissue.Specimens were taken from left three rats of subgroup,which was part of the brain tissue.The expression of NF-κB p65,around the brain tissue with immunohistochemical methods were detected.TdT-mediated dUTP nick-end labeling (TUNEL) method was used to observe the peri cell apoptosis after brain contusion.Results NF-κB p65 was expressed obviously around the lesion in 1h group,and strongly expressed in TBI-3 h-12 h,and reached a peak in 24 h after the injury,while NF-κB p65 expression reduced in TBI-3 d-7 d,and still in high expression.NF-κB p65 expression strongly correlated with the degree of cerebral edema (r =0.651,P ＜0.05).For two groups,NF-κB p65 expression strongly correlated with the level of MDA (r1 =0.947,P ＜0.01;r2 =0.961,P ＜0.01).Conclusions Changes of NF-κB protein expression after brain injury were involved in a series of pathological processes of secondary brain injury,such as oxidative stress,and apoptosis,brain-derived neutrophic factor is probably through inhibit oxidative stress levels,control apoptosis,prevent the development of vasogenic cerebral edema,and reduce or mitigate secondary brain injury.

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.

Objective To investigate the effect of pseudolaric acid B(PAB) on the expression of vascular endothelial growth factor (VEGF) in human hepatoma BEL-7402 cells. Methods BEL-7402 cells were cultured with PAB (0, 0.5, 1.0, 2.0, 4.0 and 8.0μmol · L-1) for 6 h and stained with 0.4%trypan blue. The cell viability was observed and calculated under the microscope. The cell proliferation was detected by WST-8 analysis. The expression of VEGF mRNA in BEL-7402 cells was detected using RT-PCR method. The expression of VEGF protein in BEL-7402 cells was detected using Western blot assay. Results There was no significant difference in the cell proliferation of BEL-7402 cells between different PAB treat-ment groups and control group. With the increased concentration of PAB, the expressions of VEGF mRNA were significantly decreased in different PAB treatment groups (1.90±0.02,1.31±0.03,0.86±0.04,0.60±0.03 and 0.34±0.02) compared with that of control group (2.53±0.07, P＜0.01). The expressions of VEGF protein were significantly decreased in different PAB treat-ment groups (2.60±0.09, 2.42±0.07, 1.85±0.05, 0.92±0.05 and 0.60±0.04) compared with that of control group (3.06±0.15, P＜0.01). Conclusion PAB can inhibit the expressions of VEGF mRNA and protein in BEL-7402 cells.
