Journal of Shanghai Jiaotong University(Medical Science) 2006;0(11):-
Objective To investigate the role of compound traditional Chinese medicine Yiqilin in the regulation of immune-related genes expression in spontaneously hypertensive rats(SHR).Methods Ten SHR were randomly divided into test group(fed with Yiqilin and ordinary food at the ratio of 1:9 for 6 months,n=5)and control group(fed with ordinary food for 6 months,n=5).Total RNA was extracted from myocardial tissues of SHR after 6 months,and gene chip hybridization technique was employed to analyse the expression of immune-regulated genes of myocardial tissues in two groups.The genes with differentiation expression were screened,and were verified by Real-time PCR.Results The expression of 32 immune-related genes were up-regulated in the test group,including interleukin(IL)6 receptor,IL-6 signal transduction factor,chemotatic factor,antigen presenting molecule,antibody receptor,heat shock protein(Hsp), etc.No immune-related gene was down-regulated in test group.The results of 2 immune-related genes(Hsp 105 and Hsp 90)detected by Real-time PCR were consistent with those by gene chip hybridization.Conclusion Part of the immune-related genes in myocardial tissues in SHR may be up-regulated by Yiqiling,which indicates that Yiqiling may play a role in the regulation of expression of immune-related genes in SHR.

Objective To investigate the modulation of FasL protein in colon cancer cells by interleukin 18 (IL 18) and it's effect on tumor cells counterattacking T lymphocytes. Methods By using Western blotting assay, FasL protein expression was examined in human colon cancer cell line SW620. The ratio of apoptosis of lymphocytes induced by tumor cells was studied by flow cytometry analysis. Results 10 ?g/L and 100 ?g/L IL 18 upregulated FasL protein expression in SW620 cell line, reaching the peak in 18 and 36 hours respectively, and returned to initial levels in 72 hours. The ratio of apoptosis of Jurkat cells induced by tumor cells increased in accordance with the upregulation of FasL protein. Conclusions IL 18 upregulates FasL protein expression in colon cancer cell line and enhances the ability of cancer cells to counterattack T lymphocytes.

Objective To compare the imaging of 99 Tcm‐MNLS and 99 Tcm‐HL91 for the hypoxic assessment in the tumor af‐ter radiotherapy .Methods Twenty four Kunming mice models bearing H22 liver cancer xenografts which tumor were treated ra‐diotherapy for 25 Gy were divided into 99 Tcm‐MNLS instant group ,99 Tcm‐MNLS 48 h group ,99 Tcm‐HL91 instant group ,99 Tcm‐HL91 48 h group and injected the matching 99 Tcm‐MNLS or 99 Tcm‐HL91 to image .The technique of ROI was adopted to calculated the T/NT on the image .Immunohistochemical stain methods were used to evaluate the level of HIF‐1αabout tumors after imaging . Two sample t test was performed .Results The T/NT and the HIF‐1α level about instant (3 .36 ± 0 .20 ,88 .55% ± 0 .83% )were higher than and 48 h (2 .25 ± 0 .43 ,22 .75% ± 3 .35% )in 99 Tcm‐MNLS group(P<0 .05) ,then in 99 Tcm‐HL91 group the T/NT and the HIF‐1αlevel about instant (3 .23 ± 0 .90 ,90 .55% ± 2 .61% )were higher than 48 h (2 .79 ± 0 .85 ,25 .88% ± 3 .76% )(P<0 .05) .The difference of T/NT ,HIF‐1αlevel about instant in 99 Tcm‐MNLS group and 99 Tcm‐HL91 group were no significant(P>0 .05)and the same to the T/NT ,HIF‐1αlevel about 48h in 99 Tcm‐MNLS group and 99 Tcm‐HL91 group(P>0 .05) .Conclusion 99 Tcm‐MNLS hypoxia imaging could provide the change of hypoxia comparable to 99 Tcm‐HL91 ,and the two radiopharmaceutical could both show high accuracy rate in evaluating the hypoxia in the tumor .

Objective To design and construct a vector of signal transducer and activator of transcription 3 (STAT3) small interfering RNA (siRNA),and to investigate the effect of the recombinant plasmid on the proliferation and apoptosis of gastric cancer cell SGC7901. Methods The PAVU6+27-STAT3 siRNA expression vector was constructed, then transfected into the cultured gastric cancer cells SGC7901 by DOTAP method. STAT3 mRNA and protein in SGC7901 were determined by RT-PCR and Western blotting respectively. Cell proliferation was tested by MTT and 3H-TdR incorporation. Cell apoptosis percentage and bcl-2 expression were observed by TUNEL and flow cytometry respectively. Results The PAVU6+27-STAT3 siRNA expression vector was successfully constructed. In the transfected SGC7901 cells, cell proliferation, 3H-TdR incorporation and bcl-2 expression were decreased, and cell apoptosis percentage was increased. Conclusion PAVU6+27-STAT3 siRNA expression vector may be an efficient method to inhibit the proliferation and promote the apoptosis of gastric cancer cells.

Objective To explore the technique outcome of fixing the ventral stress pedicle screws into the injured vertebrae, as a method to enhance the posterior internal fixation. Methods From March 2002 to March 2005, 33 single thoracolumbar fractures were studied retrospectively. Among which, 16 cases were treated with the above method(group A), and the other 17 were treated with traditional two-level fixation(group B). Group A involved 11 males and 5 females, aged 48 years averagely(range, 32-74 years); and group B included 12 males and 5 females, aged from 21 to 61 years(mean, 40 years). All the patients underwent the operation within up to 3 weeks after fracture. For the injured vertebral bodies, their pedicles were intact on either unilateral or bilateral side, and their lower half and endplate were free from split. In group A, the pedicle screws in the injured vertebrae were used to achieve the ventral press vertical to the distraction for the stress neutralization, and also with the routine distraction and lordosis restoration, simultaneously. The mean follow-up period was 11 months with a range from 6 to 24 months. Results After operation, the optimal Cobb angle and anterior column restoration were achieved through the ventral reduction from the injured vertebral body, which was the contribution from the vertical stress pedicle screw. The degree in anterior movement of injured vertebrae pre- and postoperatively was much more in group A than group B, and the difference was of statistical significance(P
