AIM: To explore the effect of protein kinase C-?(PKC-?) in U937 cell line inhibited by short hairpin RNA(shRNA) on the transcription of vascular endothelial growth factor(VEGF) mRNA induced by stromal cell-derived factor-1(SDF-1).METHODS: 64 bp reverse repeated motifs of PKC-? target sequence were synthesized and inserted into the plasmid to construct the plasmid expressing shRNA-PKC-?(pSIRENp) and the pSIRENp plasmid was transfected into U937 cell line.The expression of PKC-? and VEGF mRNA was detected by RT-PCR.RESULTS: The recombinant plasmid pSIRENp was successfully constructed and it nearly completely suppressed the PKC-? expression in U937 cell line.After transfection,both basical and VEGF mRNA induced by SDF-1 significantly reduced compared to control.CONCLUSION: The results shows that the short hairpin RNA of PKC? efficiently reduces its expression in U937 cells and PKC-? may be involved in the regulation of VEGF mRNA expression.

In order to construct a recombinant plasmid containing short hairpin RNA (shRNA) targeting survivin and to investigate its effect on survivin expression and cell apoptosis of human retinoblastoma cell line Hxo-rb44 in vitro, RNA interference plasmid pSIRENS that can express shRNA of survivin was designed, constructed, and transfected into human retinoblastoma cell line Hxo-rb44. Survivin and c-Myc expression was detected by reverse transcription polymerase chain reaction (RT-PCR) and Western blot. Apoptosis of Hxo-rb44 cells was assayed by Honchest33258 staining and cell growth curve was drawn. The results showed that the oligonucleotide targeting survivin was identified in pSIRENS plasmid. After pSIRENS plasmid transfected, survivin and c-Myc expression in Hxo-rb44 cells was decreased significantly. Apoptotic rate of cells was up-regulated from (3.5+/-1.29) % to (36.1+/-19.66) %. The proliferation ability of Hxo-rb44 cells was inhibited. No significant effects on survivin expression and apoptosis of the cells were found when negative control plasmid was transfected. In conclusion, the plasmid containing shRNA targeting survivin was constructed successfully. It could inhibit efficiently the expression of survivin and c-Myc in human retinoblastoma cell Hxo-rb44 in vitro. The inhibition of the expression of c-Myc might be involved in the apoptosis of Hxo-rb44 cells.

Objective To identify impacts of infection status of chronic hepatitis viruses and biochemical parameters of liver function on hepatic FDG uptake.Methods The results of 18F-FDG PET/CT,liver function biochemical tests and hepatic virus tests of 713 healthy adults (504 males,209 females,age 24-74 years) were retrospectively analyzed.Two-sample t test,correlation analysis,partial correlation analysis and multiple linear regression were performed to identify correlations of liver SUV with the biochemical parameters and hepatic viral infection status.Results HBsAg tests were performed in 449 subjects,with the results of 65 (14.5％) positive and 384 (85.5％) negative.HCV antibody tests were performed in 477 subjects,with 53 (11.1％) positive and 424 (88.9％) negative.The average SUV of the total subjects was 1.86±0.38.There was no significant difference of SUV between HBsAg positive group and negative group (t=1.042,P＞0.05),or between HCV antibody positive group and negative group (t=1.283,P＞ 0.05).Serum conjugated bilirubin,globulin and AST were significantly correlated with liver SUVmean(r'=-0.191,-0.087 and 0.132,all P＜0.05).These parameters were independent variables on predicting variance of liver SUV with globulin showing the largest predicting value (standardizedβ' =-0.112,P＜0.05).Conclusions Functional status of liver may affect liver 18F-FDG uptake.Serum conjugated bilirubin,globulin and AST may be the independent variables on predicting variance of liver SUV.Liver functional test results should be taken into consideration when hepatic 18F-FDG uptake is interpreted.

18 F?FDG PET/CT has been increasingly used in diagnosis, staging, treatment response assessment and prognosis prediction of malignant tumors. As the main organ of carbohydrate metabolism, liv?er is commonly taken as reference organ in disease diagnosis and imaging quality control. Hepatic FDG up?take in healthy people is affected by various physiological, potential pathological and imaging technical fac?tors, as well as inter?individual variation. Besides, variation of SUV caused by different calibrating methods cannot be neglected. The factors that affecting hepatic FDG uptake based on findings in recent studies are summarized in this review.

Objective To detect the levels of the mRNA expression of TIM-3,TIM-1,T-bet,GATA-3,IFN-γ,IL-4 and Galectin-9 in the peripheral blood monocytes (PBMCs) of the patients with Graves disease(GD),and to explore their potential role in the pathogenesis of GD.Methods We used fluorescence quantitative real-time reverse transcription-polymerase chain reaction to measure the mRNA expression of TIM-3,TIM-1 and other associated genes in PBMCs of 70 patients with GD and 22 healthy controls.In addition,we analyzed the relationship of TIM-3,TIM-1 and other associated genes.Results The expression of TIM-3 and TIM-1 mRNA in the PBMCs from GD patients were abnormally higher,the GD patients with Graves' ophthalmopathy group had significantly higher level of TIM-3 mRNA expression than that of GD patients without Graves' ophthalmopathy group,but no statistically significant difference was found in the expression of TIM-1 mRNA.Untreated GD patients had significantly higher level of TIM-3 mRNA expression than that of GD patients in recurrence group,however the expression of TIM-1 mRAN was opposite.But no statistically significant difference was found in TIM-3 mRNA expression of recovery GD patient and healthy control group.Though the expression of TIM-1 mRNA was significantly decreased,it was still higher than that of the normal control group.Conclusion TIM-3 and TIM-1 may participate in the occurrence,development and turnover of GD.TIM-3 or TIM-1 may prove to be an important target for developing new drugs and treatments to GD.

Objective To validate near-infrared cerebral topography (NCT) as a practical toolin tracing the regional hemodynamic changes during normal ischemic stroke model of rat. Method Middle cerebral artery occlusion (MCAO) and photosensitizer induced intracranial infarction model of rat were established. The geometric shape and infarction area were measured by NCT, functional magnetic resonance imaging (fMRI), and TTC stained anatomical imaging techniques. Result In photosensitizer induced infarction model, the correlation between anatomical infarct area and NCT image area for infarct focus were r= 0.897 for 24 h group (P<0.05) and r=0.906 for 2 months group (P<0.01),respectively. The correlation between anatomical infarction area and NCT image area for infarct focus were r=0.820 for normothermia group (P<0.05) and r= 0.851 for hypothermia group (P<0.05), respectively. The correlation between fMRI and NCT image area for infarction focus were r= 0.874 for normothermia group (P<0.05) and r= 0.782 for hypothermia group (P<0.05),respectively. Conclusion Measurement with NCT for infarction focus matched well with fMRI and anatomic sample in rats. NCT technique might be a practical tool for short-term prediction of stroke and the rehabilitation after stroke in real time.

Objective: To investigate the association between three single nucleotide polymorphisms-2562G＞A,-416C＞G and-232G＞A in Tim-3(T cell immunoglobulin domain and mucin domain protein 3)gene promoter region and child allergic asthma in Chinese Han population by using family-based association study.Methods: Genotypes of 3 SNPs(-2562G＞A,-416C＞G and-232G＞A)in 118 allergic asthma nuclear pedigrees were analyzed by restriction fragment length polymorphism.The genotype data were analyzed by using the family-based transmission disequilibrium test(TDT).Haplotypes and their frequencies were established and analyzed by TRANSMIT software.Results: ①No transmission disequilibrium was found at the-2562G＞A and-232G＞A sites from heterozygous parents onto patients in 118 trios analyzed by TDT(P＞0.05);However,at the-416 C＞G locus,the observed values of G allele from heterozygous parents to offspring were significantly higher than the expected values(P＜0.05)②The haplotype TDT analysis by TRANSMIT showed the observed and the expected value in GCA and GGA haplotype from parents to the affected offsprings had significant difference respectively(P＜0.05).The Global X~2 test results also showed that Tim-1 haplotype were associated with child allergic asthma(X~2 = 17.26, P＜0.01).Conclusion: Tim-1 gene promoter-416C＞G locus are associated with allergic asthma susceptibility in Hubei Chinese Han population and the haplotypes constructed by-416C＞G are also associated with asthma.Tim-1 genetic polymorphism may play an important role in the pathogenesis of asthma.
