Objective To evaluate the effect and the anti-tumor mechanism of nucleoside combination on human hepatoma cell line Bel-7402 with Arg-Gly-Asp sequence labeled by ultrasmall superparamagnetic iron oxide (RGD-USPIO).Methods The tumor cells Bel-7402 of logarithmic phlyhase were divided into experimental group and control group,treated with 1 mmol/L nucleoside combination and 1640 medium respectively.The two group were co-cultured for 48 h,and were added RGD-USPIO and co-cultured for 6 h.Then the two groups were proceeded with MR scanning,and the signal intensity of T2WI were measured.After extraction of the total RNA and protein of experiment group and control group,the expression of integrin avβ3 was detected using real-time PCR and Western blot.Results The T2WI signal intensity of experimental group (997.35±42.83) was higher than that of control group (241.05±15.36,t 28.79,P＜0.01).Compared with control group,the expression of integrin αvβ3 mRNA in experimental group was (0.22±0.02) times (t=4.50,P＜0.01).According to Western blot,the protein bands of experimental group were relatively lighter than that of control group,the expression of integrin αvβ3 in experimental group was lower (t =11.88,P＜0.01).Conclusion Nucleoside combination has anti-tumor effect by inhibiting integrin ligand-receptor binding,and the anti tumor mechanism may be related to the induction of tumor cell apoptosis.MR molecular probes can conveniently and accurately evaluate the anti-tumor effect of nucleoside combination on Bel-7402 cells.

Objective To describe and analyze the distribution of medical expenditure of Liaoning province in 2014 in terms of population beneficiary based on the System of Health Accounts 2011(SHA 2011).Methods By means of multistage and stratified sampling, a total of 252 medical institutions were selected from four cities in Liaoning province according to their economic status and geographical distribution.Macro data including the outpatient income and hospitalization income were taken into account, to calculate the beneficiary population of the province in 2014 according to SHA2011.Results GBD classification found that the highest medical expenditure category was non-communicable diseases, accounting for 63.02% in total medical expenditure.ICD classification found that respiratory disease as consuming the highest medical expenses (43.76%).The average medical expenditure of the elderly population was the highest per person, up to 3 041.70 yuan per person.Conclusions Medical expenses of non-communicable diseases, respiratory disease and elderly population were still high.Thus we need to emphasize disease prevention, and take efficient measures against such key diseases to curb the medical expenses.The elderly population calls for specific and effective measures to reduce their medical expenses.

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 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.

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.
