Objective:To evaluate the efficacy and safety of continuous intrathecal morphine infusion system for patients with refracto-ry cancer pain. Methods:Seventeen patients with refractory cancer pain were implanted with intrathecal catheters and connected with a continuous external electronic patient-controlled analgesia (PCA) pump for intrathecal morphine analgesia. Visual analogue scales (VAS) score, the dose of routine opioids, and the score for quality of life before and after intrathecal analgesia were recorded. Adverse reactions were observed. Results:After the application of continuous intrathecal morphine analgesia, the VAS score of pain was 2.9±1.8, which is lower than 7.2±2.5 before intrathecal analgesia (P<0.001). Moreover, the dose of routine opioids (i.e., equianal-gesic dose of morphine) was 42.1 ± 7.5 mg/day, which is significantly lower than 282.9 ± 95.5 mg/day before intrathecal analgesia (P=0.004). The scores of general activity, mood, and sleep after intrathecal analgesia were significantly lower than those before intrathe-cal analgesia (P<0.05). However, the analgesic satisfaction of patients considerably increased after intrathecal analgesia (P<0.001). Ad-verse reactions included withdrawal syndrome, headache, urinary retention, and intrathecal infection. Conclusion:The continuous in-trathecal morphine infusion with PCA is effective and safe on analgesic treatment for patients with refractory cancer pain.

Objective To investigate whether human monocyte-derived dendritic cells (DCs) can express p210 Bcr-Abl protein and induce antigen-specific CTL responses in vitro after transfection with total RNA of K562 cells (K562-RNA).Methods Immature DCs were derived from human peripheral blood monocytes after 5 day incubation in the presence of GM-CSF and IL-4. The cells were then transfected with K562-RNA using electroporation or DOTAP lipofection. To verify the successful transfection of DCs with K562-RNA, Bcr-Abl fusion gene expression was determined by RT-PCR and Western blot. The immune phenotypes of the DCs were analyzed by flow cytometry. CTL cytotoxicity was assayed by propidium iodide (PI) stain and flow cytometry. The amount of DCs, CD1a expression and purity of DCs were measured by FACS.Results Bcr-Abl fusion gene appeared in the DCs after transfection with K562 cell total RNA. But 24 hours later, the Bcr-Abl mRNA from the K562-RNA transfected DCs disappeared, while the cells were expressing p210 Bcr-Abl protein. The transfected DCs could significantly promote T lymphocytes to kill the target K562 cells. We found that PBMC can be induced to DC in culture medium containing human plasma, suggesting a potential for clinical application.Conclusion Human dendritic cells transfected by K562 total RNA can induce effective p210 Bcr-Abl protein-specific immune responses, which might broaden the spectrum of possible DC-based clinical applications.

Objective To investigate the relationship between plasma level of platelet derived growth factor-BB (PDGF-BB), coronary heart disease (CHD) and the severity of coronary artery stenosis. Methods A total of 262 patients hospitalized in Department of Cardiology, Tianjin Chest Hospital were collected in this study. According to the medical history, symptoms, laboratory examination and the results of coronary angiography, patients were divided into stable angina pectoris (SAP) group (n=57), acute coronary syndrome (ACS) group (n=119) and normal control group (n=86). The ACS group was divided into three subgroups:single vessel group (n=38), double vessel group (n=35) and multiple vessel group (n=46). The general clinical data, biochemical parameters and plasma PDGF-BB levels were compared between SAP group, ACS group and control group. Spearman correlation analysis was used to analyze the relationship between PDGF-BB level, high-sensitivity C-reactive protein (hs-CRP) and Gensini scores. Logistic regression analysis was used to analyze the risk factors of coronary heart disease. Results (1) The plasma levels of hs-CRP and PDGF-BB were significantly higher in ACS group than those in control group and SAP group (P<0.05). (2) Spearman correlation analysis showed that there was no correlation between plasma levels of PDGF-BB and hs-CRP and Gensini score (P>0.05). (3) There was no significant difference in plasma level of PDGF-BB between single vessel group, double vessel group and multiple vessel group (P > 0.05). (4) Logistic regression analysis showed that high plasma level of PDGF-BB was the risk factor for coronary heart disease. Conclusion PDGF-BB plasma level is associated with the pathogenesis of coronary heart disease, which may reflect the instability of coronary atherosclerotic plaques, but it is not an index to evaluate the severity of coronary stenosis.

Objective To disclose the inter-species differences among Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L using AFLP analysis. MethodsThe root, stem, foliage, flower, seed of Papaver somniferum L, foliage of Papaver rhoeas L and Cannabis sativa L were collected respectively. DNA was isolated with AxyPrep Kit, and double-digested by EcoR I and Mse I, then oligonucleotide adapters were ligated. After Pre-amplification, selective amplification was performed using 6 pairs of fluorescent primer. The DNA fragments were analyzed using a CEQ 8000 DNA Fragment Analyzer. Results27 to 46, 5 to 20 and 4 to 31 pieces of amplified products were detected from Papaver somniferum L, Cannabis sativa L and Papaver rhoeas L respectively, and significant difference was observed among these three groups of products. The identical species-specific peaks were identified from root, stem, leaf, flower and seed DNA from the same Papaver somniferum L. ConclusionThe diacritical results from Papaver somniferum L, Papaver rhoeas L and Cannabis sativa L, as well as the identical results of different parts from the same plant demonstrated that AFLP analysis could be used possibly to determine the species origin of unknown plants samples.

AIM: To study the effects of (-)-epigallocatechin-3-gallate (EGCG), a tea extract, on the invasion and metastasis of breast cancer cell line MDA-MB-231 and the possible mechanisms in vitro. METHODS: The expression of MUC1 in breast cancer cells treated with or without EGCG was detected by immunohistochemistry. The effect of EGCG on invasion of MDA-MB-231 cells was evaluated using Transwell chambers attached with polycarbonate filters and reconstituted basement membrane (Matrigel). Gelatin zymography was performed to detect the secretion of collagenase-Ⅳ. RESULTS: EGCG reduced the expression of MUC1, significantly suppressed the invasion of tumor cells to basement membrane and reduced the secretion of collagenase-Ⅳ. CONCLUSION: In vitro, EGCG may suppress invasion, metastasis, and collagenase-Ⅳ secretion in MDA-MB-231 cells by inhibiting the production of MUC1.

Objective To observe the effect of sesamol on the hematopoietic system in mice exposed to 4 Gy irradiation. Method Twenty C 57 BL/6 mice were randomly divided into control group, sesamol group, irradiated group and irradiated+sesamol group (n=5). Mice of control and sesamol group received sham irradiation, and the rest exposed to 4 Gy total body irradiation, dose rate 1.01 Gy/min. Mice in sesamol group and irradiated+sesamol group received a dose of 10 mg/kg sesamol administered by gavage every day for 7 days after irradiation exposure. Mice of other two groups were treated with vehicle solution. After 4 Gy irradiation 7 day, the peripheral bloods were collected. The levels of colony forming units-granulocyte-macrophage (CFU-GM) were detected. Results Compared to irradiation group, the level of WBC、cell count of BMNCs and CFU-GM significantly decreased in the irradiated mice, decreased in the irradiated mice (P<0.05). Compared to irradiation group, cell count of BMNCs and CFU-GM in the irradiated+sesamol group increased significantly (P<0.05). Conclusion Sesamol has a certain impact on the radiation-induced changes in hematopoietic system. The mechanism need to be further explored.
