1.Epithelial tumor development and exploration on the relationship between matrix
Practical Oncology Journal 2015;(6):569-572
We have confirmed that many of the intraepithelial neoplasia confined to in situ may never be found in some patients ,such as breast ,prostate and lung lesions ,but few of these lesions progress to malignancy are unexplained .Studies demonstrate that many invasive neoplasia and its precancerous lesions with similar genes changes,which provide the necessary premise for the late tumor metastatic ,just like specific promoter mutations driving the cancer development ,but the current radical view is that the mutations of the genes are not the driver of cancer development ,rather the microenvironment of the cells inhibits or promotes the development of tumor .Gen-eral view is that the epithelial cells are changed before the cell matrix in the development of neoplasia ,but recent evidences show that the cell matrix is the first to change .This paper will focus on how matrix changes affect the epithelial tumor development ,and this will bring new breakthrough for controlling epithelial tumors .

Objective To establish a TaqMan-MGB fluorescent probe characterized real-time polymerase chain reaction ( qPCR) method for detecting retinoic acid induced genes G ( RIG-G) in human acute promyelocytic leukemia ( M3 ) .Analyze RIG-G expression levels in peripheral blood of both normal persons and M3 patients and explore its diagnosis value for M 3.Methods Methodology establishment study.A detection method and standard curve of TaqMan-MGB real-time PCR were established after designing specific primers and TaqMan-MGB fluorescence probe of human RIG-G gene and using reverse transcription complementary DNA ( cDNA) as a template.The performance of this method was evaluated in specificity, accuracy, precision, analytical sensitivity and interference substances . Twenty clinical specimens with M3 were quantified RIG-G expression so as to evaluate the correlation between peripheral blood and bone marrow samples .Meanwhile , the results of RIG-G expression in peripheral blood of 40 normal specimens and 20 patients with M3 were analyzed by t-test.And receiver-operating characteristic curve ( ROC ) was used to analyze the detection efficiency of M 3.Results There was a good linear relationship between log value of RIG-G standard substance and threshold cycle number ( Ct ) ( standard curve equation:Y=-3.539X+42.952,R2 =0.999).New method was used to detect standard substance . The deviation between observed and expected values was <5% (r=0.999).Three concentration samples (107 ,104 ,101 copies/μl) were selected for precision test.Intra-assay coefficients of variation were 1.38%, 2.31% and 1.38%, respectively , and intre-assay coefficients of variation were 0.71%, 1.17% and 5.07%, separately.All were less than 10%.The sensitivity of this method was 101 copies/μl.There was a good correlation of RIG-G results between peripheral blood and bone marrow in M 3 patients(r=0.996, b=0.973).But there was no significant difference between this two group results (t=0.099, P>0.05). However , there was obvious difference of RIG-G value in peripheral blood between control group and M 3 patient group (U=18,P<0.001), 3.62 ×104(1.61 ×104 -4.90 ×104)copies/μl for controls and 7.10 ×102 (5.43 ×102 -2.21 ×103 ) copies/μl for M3 patients, respectively.Conclusions Successfully establishe a TaqMan-MGB real-time PCR method for detecting RIG-G gene in peripheral blood.The accuracy, precision, sensitivity and specificity are good .It could provide necessary help in early diagnosis and monitor treatment of clinical M3 patients.

BACKGROUND:Some studies have showed that the accuracy and surgery outcome of the percutaneous pedicle screw implantation was superior to open surgery, but the relationship between the angle of pedicle screws and screw stability is stil unclear in previous studies. OBJECTIVE:To investigate the effect of different angles of implanted screws on the stability of pedicle screw. METHODS:A total of 30 vertebral specimens of adult pigs were selected and screws were implanted respectively according to different coronal and sagittal angles. The maximum pul-out strength of screws from each specimen was tested by machine. Load-displacement curves were drew and statistical y analyzed. RESULTS AND CONCLUSION:The maximum pul-out strength and maximum energy of screw with 10° and 15° coronal and sagittal angles implantation were significantly better than those of 0° angle group (P<0.05). When the stress exceeded the maximum pul-out strength, the pul-out strength of screw decreased gradual y. The curves in coronal and sagittal 10° and 15° angle groups was similar, and the slope was better than 0° angle group (P<0.05). These results confirm that the angle of the implanted screw provides effective assistance to the stability of percutaneous pedicle screw. After the looseness of the screws, the pul out strength shows a steady downward trend.

BACKGROUND: Antiviral drugs can reduce the incidence of early-onset cytomegalovirus(CMV)disease,but are associated with strong toxicity and the development of late-onset CMV disease.In order to prevent CMV disease better,cytotoxic T lymphocytes(CTL)may play a critical role in controlling CMV reactivation.Fluorescent HLA-peptide tetramers are used to monitor the recovery of CMV CTL in recipients of allogeneic transplants.OBJECTIVE: To explore the effect of HLA-peptide tetramers and adoptive immunotherapy in treating CMV disease.METHODS: A computer-based online search of Pubmed and Wanfang databases was performed for articles related to CTL detection,application of antiviral drugs and HLA-peptide tetramers,and adoptive immunotherapy with key words"HLA-peptide tetramers,cytomegalovirus,specific CTL,adoptive immunotherapy"in English and Chinese.Repetitive articles were excluded and 29 articles were included.RESULTS AND CONCLUSION: Adoptive immunotherapy with CMVs cytotoxic T cells as preemptive therapy is a very elegant strategy; however,generation of these cells is costly and time-consuming,and therefore the therapy is not available at every transplantation center.Magnetic selection of CMVs CD8+T cells from peripheral blood of CMV-seropositive donors by using HLA-peptide tetramers may be very hopeful,which simplifies adoptive immunotherapy.
