Objective:To evaluate the clinical value of radioactive nuclide strontium chloride (89SrCl2) combined with 99Tc-MDP in treating patients with breast cancer and osseous metastasis. Methods:A total of 80 patients with breast cancer and experiencing bone pain from osseous metastasis were randomly categorized into three groups. 22 patients were treated with 99Tc-MDP (99Tc-MDP group), 30 were treated with 89SrCl2 (89SrCl2 group), and 28 were treated with the combination therapy of 89SrCl2 and 99Tc-MDP (combination group). The analgesic effect, remission of bone metastases, and quality of life of patients in the three groups were observed before and after treatment. Side effect was also monitored. Results:In the combination group, the overall pain relief rate and the increase rate of life quality score were 92.9%(26/28) and 78.6%(22/28), respectively. The combination group was statistically significantly different from the two single-treatment groups (P<0.05). The effective rate of metastatic lesions was 46.4%(13/28) in the combination group, which was significantly higher than that in the 99Tc-MDP group (18.2%, 4/22;P<0.05). The effective rate of metastatic lesions was not significantly different between the combination and 89SrCl2 groups (33.3%, 10/30) (P>0.05). Conclusion:The treatment of 89SrCl2 com-bined with 99Tc-MDP can increase the analgesic effect and significantly improve the curative effect without overt side effects in patients with breast cancer and bone metastasis.

This study examined the anti-hepatitis B virus (HBV) effect of wild-type (WT) vacuolar protein sorting 4B (VPS4B) and its dominant negative (DN) mutant VPS4B-K180Q in vivo in order to further explore the relationship between HBV and the host cellular factor VPS4. VPS4B gene was amplified from Huh7 cells by RT-PCR and cloned into the eukaryotic expression vector pXF3H. Then, the VPS4B plasmid and the VPS4B-K180Q mutation plasmid were constructed by using the overlap extension PCR site-directed mutagenesis technique. VPS4B and HBV vectors were co-delivered into mice by the hydrodynamic tail-vein injection to establish HBV vector-based models. Quantities of HBsAg and HBeAg in the mouse sera were determined by ElectroChemiLuminescence (ECL). HBV DNA in sera was measured by real-time quantitative PCR. Southern blot analysis was used to assay the intracellular HBV nuclear capsid-related DNA, real-time quantitative PCR to detect the HBV-related mRNA and immunohistochemical staining to observe the HBcAg expression in the mouse liver tissues. Our results showed that VPS4B and its mutant VPS4B-K180Q could decrease the levels of serum HBsAg, HBeAg and HBV-DNA. In addition, the HBV DNA replication and the mRNA level of HBV in the liver tissues of treated mice could be suppressed by VPS4B and VPS4B-K180Q. It was also found that VPS4B and VPS4B-K180Q had an ability to inhibit core antigen expression in the infected mouse liver. Furthermore, the anti-HBV effect of mutant VPS4B-K180Q was more potent than that of wild-type VPS4B. Taken together, it was concluded that VPS4B and its DN mutant VPS4B-K180Q have anti-HBV effect in vivo, which helps develop molecular therapeutic strategies for HBV infection.

Objective To investigate the influence and mechanism of erythropoietin (EPO) in renal blood flow after limb ischemia reperfusion (LIR). Methods Thirty male SD rats were randomly divided into control group, LIR group and EPO+LIR group with ten in each group. The values of renal blood flow, plasma creatinine (Cr), urea nitrogen (BUN) content in plasma, kidney tissue wet to dry ratio (W/D), nitric oxide (NO), nitric oxide synthase (NOS) and endothelin-1 (ET-1) in re-nal tissue were detected in three groups. The immunohistochemistry assay was used to detect the expression of intercellular adhesion molecule (ICAM-1) and vascular cell adhesion molecule (VCAM-1) in renal tissue. The morphological changes of renal tissue were observed with light microscope. Results The renal blood flow was significantly decreased, while the val-ues of Cr, BUN, W/D, NO, ET-1, NOS, expressions of ICAM-1 and VCAM-1 was significantly increased in LIR group than those of control group (P<0.05). Broaden interstitial and infiltration of inflammatory cells were observed in the renal tissue under light microscope. In the EPO+LIR group, the renal blood flow increased, the values of Cr, BUN, W/D, NO, ET-1 and NOS, expressions of ICAM-1 and VCAM-1 decreased significantly compared with those of LIR group (P<0.05). The patho-logical changes were alleviated in EPO+LIR group. Conclusion EPO can improve renal function, increase renal blood flow in rats after LIR. The mechanism may be related to the decreased edema, changed renal vasomotor function and decreased in-flammation.
