Objective To investigate the significance of the expression levels of humans telomerase reverse transcriptase(hTERT) gene in peripheral blood mononuclear cells with lung cancer patients. Methods From Mar.2002 to Feb.2005,the expression levels of hTERT were detected in 30 lung cancer patients and 15 normal humans by quantitative measurement with RT-PCR. Results The expression levels of hTERT mRNA in lung cancer patients (0.906?0.112) were significant as compared with those health controls(0.407?0.104). Conclusion It is effective to diagnose lung cancer by the quantitative measurement with RT-PCR for the expression levels of hTERT mRNA.

Objective To summarize the effect and experience of nursing of patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replace-ment operation. Methods A retrospective analysis was carried out in the nursing of 58 patients with rheumatic valvular heart disease with atrial fibrillation treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation in our hospital from April 2006 to July 2008. Results One patient died of periop-erative renal failure,one died of low cardiac output,one died of infectious endoearditis.Tbe mortality rate reached 5.2%.Other patients were discharged from hospital after completely cured.The survived patients maintained sinus rate during hospitalization days after operation and short-term follow-up after being dis-charged.Among 43 patients who completed follow-up of 6 months after operation,3 patients (7.0%) damon-strated atrial fibrillation,while others still kept sinus rate. Conclusions Attention should be paid to psy-chological nursing,respiratory tract preparation,cardiac function monitoring and nursing of anticoagulation treatment for patients treated with Cox Ⅲ labyrinth and simultaneous valve replacement operation.

Inflammatory bowel disease (IBD) is a bowel disease with uncontrolled inflammation and unknown etiology.With the recent expert consensus,multidisciplinary collaborative groups focusing on IBD have been gradually built in China,and IBD is not only an internal medical disease anymore.Furthermore,the therapeutic effect of IBD has also been greatly improved,but it is still not satisfactory.Precision therapy is the future direction of treatment for IBD,meanwhile,stem cell therapy and fecal transplantation also provide the new choices for refractory IBD.

Objective To investigate the expression of nerve growth factor receptors, P75 neurotrophin receptor (P75~(NTR)) and tyrosine kinase A (TrkA), and to explore their role in the pathogenesis of psoriasis vulgaris. Methods In situ hydridization and immunohistochemical technique were used respectively to detect the expression of P75~(NTH) and TrkA mRNA and proteins in lesional and non-lesional skins of 38 patients with psoriasis vulgaris (21 cases in progressive stage, 17 cases in static stage), and in normal skins of 10 healthy controls. Results In the case of expression of P75~(NTR) and TrkA mRNA and proteins, patients had significantly higher level than the normal control (P

Purpose To investigate the expression and significance of epiderma1 growth factor receptor( EGFR)mutation-specific anti-bodies in 1ung adenocarcinoma. Methods Immunohistochemica1( IHC)technique was used to detect the expression of EGFR muta-tion-specific antibodies(EGFR-19,EGFR-21)and EGFR tota1 protein antibody(EGFR-P)in 171 cases of 1ung adenocarcinoma with resected specimens,and EGFR gene mutation was a1so performed by amp1ification refractory mutation aystem-PCR( ARMS-PCR). The expression of EGFR-19,EGFR-21 and EGFR-P mutant proteins was compared with EGFR gene mutation and their re1ationship with histo1ogica1 c1assification and c1inica1 characteristics were ana1yzed. Results The expression of EGFR mutant protein was corre1ated with the poor differentiation group inc1uding micropapi11ary and so1id predominant types( P=0. 021 ). EGFR-21 high expression was re1ated to p1eura1 invasion(P=0. 005). The coherence of IHC(with EGFR-19/21 antibodies)and ARMS-PCR was existed(Kappa>0. 4 ). Taking ARMS-PCR as a standard,the sensitivity and specificity of EGFR-19 and EGFR-21 were 65. 0% and 89. 4%, 70. 0% and 97. 6%,respective1y. Conclusions Expression of EGFR mutation-specific antibodies is associated with poor differentia-tion and p1eura1 invasion. It suggests a worse prognosis indicator in 1ung adenocarcinoma. Because of the coherence with ARMS-PCR, using IHC with mutation-specific antibodies to detect the mutant proteins of EGFR-19/21 may act as a pre1iminary screening method of EGFR gene mutation.

Objective To detect the level of Th1 and Th2 type cytokines of peripheral blood CD+3 T lymphocytes in patients with breast cancer, in order to find out the laboratory evidence of tumor immunotherapy. Methods The peripheral blood lymphocytes were stimulated by stimulator in order to enhance expression of cytokines. Specific fluorochrome-conjugated monoclonal antibody combined with antigen. Cytokines were detected by flow cytometry and ELISA. Results Both the cytokines secreted by CD+3 T lymphocytes and serum cytokines showed that the level of Th1 type cytokines such as interferon-?(IFN-?), interleukin-2(IL-2), interleukin-12(IL-12) were significantly lower in patients of breast cancer than those of normal controls. The level of Th2 type cytokines such as interleukin-4(IL-4), interleukin-10(IL-10) were higher in patients of breast cancer than those of normal controls. There was significant difference between them. The level of tumor necrosis factor ? (TNF-?)in patients were significant higher than normal control. Conclusion Th1/Th2 was imbalance in mammary cancer. Th1 type cytokines were inhibited, and Th2 type cytokines were relatively enhanced, so Th1/Th2 shift to Th2. It maybe the mechanism of tumor arising and transferring by immune escaped from immunosurveillance.

Objective To observe the iodine state of patients with autoimmunity thyroid disease(AITD) in Shaanxi province,and to discuss the relationship between the metabolism of iodine and the occurrance,development and prognosis of AITD.Methods A total of 388 cases were collected,among whom 283 were patients with AITD,and 105 were patients with non-AITD.Questionnaires were designed to determine the general state of the patients,the size,shape and texture of the thyroid,the urinary concentration of iodine,the function of thyroid and the autoantibody of thyroid.The data were processed by SPSS12.0.Results The mean urinary concentrations of iodine in patients with GD,with HT,and the control group were 212?g/L,245.4?g/L,and 197.8?g/L respectively,which were statistically different.In the HT group,wich different urinary concentrations of iodine,there were no statistical difference of TGAb,TMAb,and HS-TSH.Conclusion Excessive in-take of dietary iodine may be related with AITD.

Based on the counting results from nutrition agar in our study, and compared with another two kinds of coliform bacteria detective plates for dinner and drinking sets which were provided by two manufactures and inspected by China National Health Bureau , we accomplished the detectability test of the Huankai coliform bacteria plates. In our study, 3kinds of cell density were adopted: 10cells/mL, 50cells/mL and 100cells/mL . The results shew that the detectability of Huankai plates basically conformed with that of nutrition agar , and was no evident difference from that of another two kinds of plates. The conclusions were that Huankai plates can completely be used in the inspection and test for conform bacteria.

Human kerotinocyte growth factor (hKGF) gene amplified by PCR was inserted into the shuttle vector pAdTrack-CMV to get the recombinant plasmid pAdTrack-CMV-hKGF, which was linearized with Pme I and transferred into Escherichia coli BJ5183 containing the adenoviral bone plasmid pAdEasy-1 to obtain the recombinant adenoviral plasmid pAdEasy-hKGF. The recombinant adenoviral plasmid was then transfected into HEK-293 cell lines via Lipofectamine 2000 to package and amplify the recombinant adenovirus containing hKGF gene detected by PCR. The recombinant adenovirus produced could effectively infect HaCat cells. The result of Western blotting showed that HaCat cells infected with the recombinant adenovirus expressed and secreted hKGF protein.
