Purpose To investigate the expression of insulin-like growth factorIImRNA binding protein 3 ( IMP3 ) and microvessel density (MVD) in squamous carcinoma of the cervix (SCC) and analysis their relationship in SCC. Methods The expression of IMP3 and MVD was examined by immunohistochemistry SP method in normal cervical epithelium ( NCE) , low-grade cervical intraepi-thelial neoplasia (CIN-L), high-grade cervical intraepithelial neoplasia (CIN-H) and SCC. Results (1)The positive expression rates of IMP3 in NCE, CIN-L, CIN-H, SCC tissues were 0(0/15), 0(0/11), 37.5%(9/24) and 86.0%(43/50), the difference was statistically significant (x 2 =53.345, P=0.000). IMP3 expression was significant difference among NCE and CIN-H, SCC (P<0.008 3), and that was also among SCC and CIN-L, CIN-H (P<0.008 3). (2)The MVD count was increased with the development of cervical squamous lesion, there was significant difference among those groups (F=145.968, P<0.01), and the difference was al-so statistically significant between every two groups (P<0.05). The positive expression of IMP3 and MVD count in 50 cases of SCC tissues showed statistical difference in different pathologic grade, lymph node metastasis, and depth of tumor invasion groups ( P<0.05), but didn't in different patients’age groups (P>0.05). And the positive expression of IMP3 was closely related with MVD count in SCC tissues (rs =0.323, P<0.05). Conclusion IMP3 plays an important role in the occurrence, infiltration and metasta-sis of SCC, and the abnormal expression of IMP3 may relate with the angiogenesis of tumors.

Objective To evaluate the feasibility of CT staging for esophageal cancer. Methods A retrospective analysis of 304 patients treated,from Jan. 1996 to Dec. 1998 chiefly with radiotherapy(126 conventional radiotherapy,55-65 Gy/27-35 fx/5.5-7.0 w;178 late-course accelerated hyperfractionated radiotherapy ,55-60 Gy/33-36 fx/ 4.5 -5.5 w)complete with CT data before treatment was done. The long survival was compared with pre-therapy CT findings and CT staging. ResultsThe survival rate of stage T1+T2 was very significantly different from those lesion with stage T3,T4(? 2=12.90,P0.05).The survival rates of patients positive for lymph nodes or distant metastasis were lower. Conclusion CT staging is quite optimal for non-operable esophageal cancer in clinical staging,as it is conducive to predict the prognosis.

AIM: To investigate the effect of CD_8+ cells from aplastic anemia (AA) patients and its histamine type II (H_2) receptors on the growth of normal CFU-Mk. METHODS: The effects of CD_8+ cells and/or cimetidine, on normal human CFU-Mk growth were studied by using CFU-Mk assay. RESULTS: The CD_8+ cells from the perpheral blood of AA patients significantly suppressed the growth of normal allogeneic CFU-Mk. This inhibitory effect was blocked by cimetidine at concentration of 1.0?10~-5 mol/L. 1.0?10~-5 mol/L cimitidine alone didn't inhibit the growth of normal CFU-Mk. CONCLUSION: H_2 receptor antagonist cimitidine abolishes the suppressive effect of AA patients CD_8+ cells on the growth of normal CFU-Mk.

Objective To measure serum ghrelin level in elderly Chinese, and investigate the relationship of the serum ghrelin level with age, obesity and other metabolic disorders. Methods A total of 109 men aged over 60 years without history of smoking and alcohol consumption from health examination were enrolled in this study. Subjects were excluded if they had serious diabetic complications, coronary artery disease and hepatic or renal dysfunction. A cross sectional study was made on ghrelin level and the correlated metabolic disorders. Results Compared with ghrelin level in subjects with normal BMI [(823. 57±410.40) ng/L], the ghrelin level was significantly decreased in overweight and obese elderly male, [(442.42 ± 171.10) ng/L and (434.64 ± 177.65) ng/L respectively]. ghrelin was significantly lower in subjects with three or more metabolic disorders (420.84±165.91) ng/L than in those with less disorder. Single factor analysis showed ghrelin was inversely associated with BMI, TG and uric acid (r=-0.359,-0.243,-0.189), but it was not associated with age, blood pressure, fasting glucose and insulin levels. Multivariate analysis revealed only BMI significantly affected the level of ghrelin (β =-0.386). Conclusions BMI is closely associated with ghrelin in elderly male,ghrelin is significantly lower with increased number of metabolic disorders.

In the cultural construction of independent institute,there exist the contradiction between tradition and innovation,cultural conflicts between private enterprises and the university.Therefore,adhering to the people-centered concept,coordinating tradition and innovation,merging the advantages of university culture and private enterprises culture into a whole,cultivating the unique spiritual culture,harmonious system culture and unified material culture of independent institute,forming the distinctive “Institute Culture” with its own cultural tradition will provide reference for the theory and practice to enrich and improve the connotative development of independent institute.

Objective To search for the reasons of high positive rate of amotile bacteria and the diagnosis of septicemia in new-born Methods The blood was drawn from the different site of the new-born with septicemia and carricd out blood culture. The drug sensitivity test had been done by the method of paper stripdiffusion. The plasmids of bacteria were extracted rapidly by medified Birnboim method and the plasmid analyss was carried out. The plasmids's DNA of 35 epidemic strain was cut off by both restriction enzyme of Hind Ⅲ and EcoR Ⅰ. The outer membrane protein (OMP) was determined by SDS-polyacrylamide gel electrophoresis.Results There are 51 patients with positive blood culture amotile bacterium,of them, pollution; 35 cases (68．6%), septicemia: only 16 cases (31．4%),54．8% (57/104) strains bacteria have drug resistance to more of 12 drugs. 87．3% (165/189) strains bacteria have plasmids. They are cut off as 6 DNA fragments (1．9,2,4,5, 8．5 and 18Kb) by Hind Ⅲ restrietion enzyme. and as 5 DNA fragments (2,2．6,3．2, 6．3 and 22 Kb) by EcoR Ⅰrestrietion enzyme, it is showed that they come from a same clone. The epidemic strain include 10 slips OMP, but non-epidemic strain have 11 slip OMP, increase a 25Kd belt. The amotile bacteria with above-mentioned plasmid spectrum, restriction enzyme spectrum and OMP spectrum are only seen in the air, therapeutic dish and syringe needle.Conclusion The pollution is an important reason of amotile bactorium high positiye rate in new-born.Diagnosing septicemia should depend on bacteria culture, plasmid analysis restriction enzyme analysis of plasmid DNA, oMP determination and combining medical history and clinical manifestation.
