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 The aim of this study was to investigate the co-operative role of HGF and IL-1ra in metastatic processes by interactions between colon cancer cells and stromal cells in their microenvironment.Methods Expression of IL-1α,HGF and c-Met mRNA and proteins were determined by RT-PCR and Western blot.The effect of HGF on metastatic potential was evaluated by proliferation,invasion,and angiogenesis assays using an in vitro system consisting of co-cultured tumor cells and stromal cells.Results IL-1α expression was closely correlated with metastatic potential,and cancer cell-derived IL-1α significantly promoted HGF expression by fibroblasts (P ＜ 0.01).HGF enhanced the migration and proliferation of human umbilical vein endothelial cells (HUVECs),and angiogenesis (P ＜ 0.01).The high liver-metastatic colon cancer cell line (HT-29),which secretes IL-1 α,significantly enhanced angiogenesis compared to the low liver-metastatic cell line (CaCo-2),which does not produce IL-1 α (P ＜ 0.01).IL-1 ra significantly inhibit migration,proliferation and angiogenesis (P ＜ 0.01).Conclusions Autocrine IL-1α and paracrine HGF enhance the metastatic potential of colon cancer cells;IL-1ra inhibit the metastatic potential of colon cancer cells by blocking IL-1α and HGF signaling pathways.

Objective To assess the clinical efficacy of human neural stem cell (hNSC) transplantation in the treatment of severe cerebral palsy (CP) in children.Methods hNSCs were obtained from the forebrain of 10 to 12-week-fetus.Forty children with CP were voluntarily received hNSC transplantation that were injected into cerebral ventricle.The development of motor and fine motor functions were evaluated by GMFM and PDMS-FM 1 month before hNSC transplantation.as well as 3 and 6 months after hNSC transplantation.Results Twenty six (65％) cases displayed improvement from day 5 to month 6 after hNSC transplantation.GMFM assessment showed that the percentage was (4.52±2.50) ％ 1 month before hNSC transplantation,(7.74±2.94) ％ 3 months after hNSC transplantation and (13.01±6.71)％ 6 months after hNSC transplantation,indicating a significant improvement by the treatment of hNSC transplantation(P＜0.05).The percentage in PDMS-FM evaluation was (15.01± 12.00)％,(20.34± 11.91) ％ and (30.02± 12.50) ％ one month before hNSC transplantation,3 and 6 months after hNSC transplantation,respectively,also suggesting a significant improvement induced by hNSC transplantation treatment (P＜0.05).Moreover,the developmental improvement was the most prominent among 1-3 months post hNSC transplantation.Then the development slowed down.Significantly,patients received no hNSC transplantation experienced serious adverse events or complications.Conclusions hNSC transplantation is an effective and safer therapy for severe CP.Future observations are needed to evaluate long-term clinical efficacy of the therapy.

Objective To investigate the effects of supreme laryngeal mask airway (SLMA) and endotracheal intubation on the elderly hypertensive patients treated with knee arthroplasty. Methods Forty cases of elderly hypertensive patients ASA Ⅰ-Ⅲ treated with knee arthroplasty in our hospital were selected and randomly divided into laryngeal mask airway group (group LMA)and endotracheal intubation (group TT),20 cases for each group.The same protocol for induction and maintenance of general anesthesia was used.After the patients entering,the changes of SpO2 and ECG were performed continuous noninvasive monitoring and SBP,DBP and HR were performed con-tinuous invasive monitoring.SBP,DBP and HR of two groups were recorded at different time points:before anesthesia induction (T0 ,based value),at intubation immediate (T1 ),5 mins after intubation (T2 )and 1 5 mins after intubation (T3 ).At the same time,the content of cortisol (Cor),atrial natri-uretic peptide (ANP)and the concentration of epinephrine (E)and norepinephrine (NE)were meas-ured at the corresponding time points above.Results Compared with T0 ,SBP and DBP at T1-T3 in group LMA were decreased(P <0.05 or P <0.01);SBP and DBP at T1 in group TT were increased while decreased at T2 ,T3 ,HR at T1 were increased(P < 0.05 or P < 0.01 ).Compared with group LMA,SBP and DBP at T1-T3 and HR at T1 ,T2 in group TT were increased (P <0.05 or P <0.01). Compared with T0 and group LMA,the content of E,NE and Cor at T1-T3 increased(P <0.05 or P <0.01).The level of ANP in both groups at T1-T3 were higher than those at T0 ,and group TT were higher than group LMA(P <0.01).Conclusion Compared to endotracheal intubation,SLAM can ef-fectively reduce the stress reaction of elderly hypertensive patients treated with general anesthesia in knee arthroplasty.
