0.05). No significant differences were detected in the median time of remission, median survival time and 1-, 2-year survival rates between the groups. Moreover, no significant differences were detected in the grade Ⅲ~Ⅳ leukopenia, grade Ⅲ~Ⅳ thrombocytopenia, grade Ⅲ~Ⅳ nausea and vomiting and grade Ⅲ~Ⅳ constipation between the groups. Conclusions:The response rate of the MVP regimen is slightly lower than the HMVP regimen, but the HMVP regimen is not noticeably superior. It may increase the toxicity such as leukopenia, nausea/vomiting and constipation, as wellas being more expensive. In short, MVP regimen should be selected between the regimens in the chemotherapy of advanced NSCLC.

The purpose of this study is to evaluate the effect of oligomeric grape seed proanthocyanidins (GSP) on isoproterenol (ISO)-induced cardiac remodeling in rats. ISO was given subcutaneously (5 mg x kg(-1), sc, 7 days) to induce cardiac remodeling in rats. Therapeutic groups were given GSP (50, 100, and 150 mg x kg(-1)) after ISO treatment. After 2 weeks intervention, heart rate (HR), left ventricular systolic pressure (LVSP), left ventricular end-diastolic pressure (LVEDP), rate of rise of left ventricular pressure (+/- dp/dt(max)) were examined. The myocardial hypertrophy index was expressed as heart weight/body weight (HW/BW) and left ventricle weight/body weight (LVW/BW), the histological changes were investigated by HE and Van Gieson stain. SOD activity and MDA content in serum, contents of hydroxyproline (Hyp) in the left ventricular tissue were assayed by xanthinoxidase method, thiobarbituric acid (TBA) method and alkaline hydrolysis method, respectively. After the onset of ISO-treatment, GSP therapy potently improved cardiac function, inhibited myocardial hypertrophy, improved cardiac pathology change, decreased the myocardial cross-section area (CSA), collagen volume fraction (CVF) and perivascular circumferential collagen area (PVCA), reduced the content of Hyp in the left ventricular tissue, inhibited the decrease of SOD activity and increase of MDA content in serum. GSP possess protective effect against ISO induced cardiac remodeling in rats, this may be related to reducing the oxidative stress and improving antioxidant capacity.

BACKGROUND: Our former studies have shown that bone marrow mesenchymal stem cells (BMMSCs) can be induced differentiation to vascular smooth muscle-like cells (VSMLCs) and vascular endothelium-like cells (VELCs), which are compatible with collagen-embedded polyglycolic acid scaffolds. OBJECTIVE: To investigate the possibility of constructing small diameter tissue-engineered blood vessels via subcutaneous implantation. METHODS: The cells-scaffold complex was produced by separately seeding VSMLCs and VELCs derived from BMMSCs on polyglycolic acid collagen scaffolds. The two layers were separated by ECMgel. The cells-scaffold complex was subcutaneous implanted into small diameter tissue-engineered blood vessels.RESULTS AND CONCLUSION: Histological analysis of the small diameter tissue-engineered blood vessel walls revealed a typical artery structure, which was similar to natural vessels. The tissue-engineered blood vessels were not broken down under a force of 26.6 kPa. Eight weeks after implantation, the Brdu-labeled seed cells were found in the three layers of the vessel walls. The results revealed that the subcutaneous tissue was a good bioreactor to construct small diameter tissue-engineered blood vessels.

Objective To evaluate the effects of pregabalin combined with hydrochloric oxycodone on patients with ma-lignant neuropathic pain (MNP). Methods A total of 66 patients with MNP was divided into control group or treatment group randomly. The patients in control group received only hydrochloric oxycodone, and treatment group were treated with the combina-tion of pregabalin and hydrochloric oxycodone. Numeric rating scale (NRS) score was used to evaluate the analgesic effects. Med-ical outcomes study sleep scale (MOS-SS,Chinese version) was used to evaluate the improvement of sleep disorder. The changes of depression or anxiety were investigated by 17-item Hamilton Depression Rating Scale (HAMD-17) or Hamilton Anxiety Scale (HAMA), respectively. Side effects were accessed by Acute and Subacute Toxicity Grading Criteria of Anticancer Drugs (WHO). Results The pain control rate of treatment group was 87. 1% , which was superior to that of control group (58. 6% ) (P<0. 05). The improvement of sleep interference, and the quality and quantity of sleep in treatment group were also superior to that in control group (P<0. 05). After the treatment, depression and anxiety was attenuated in both groups, and the improvement degree in treatment group was higher than that in control group (P<0. 05). No obvious side effects were found in either groups. Conclusion The combination therapy of pregabalin and hydrochloric oxycodone is the better way to treat MNP.

ObjectiveTo study the effect on humoral immunity with combination of CsA and IL-2 fusion protein. MethodsForty C57/B6 mice were evenly divided into four groups,after receiving skin graft from DBA mouse.Mice in the experimental group was given CsA(30 mg/kg,ip) plus IL-2/Fc (1μg,ip) while the control group was only given CsA,each group was given HBV vaccine after skin graft surgery (2 μg,im),while blank group was only given vaccine after skin transplantation.The fourth group were left intact.Fourteen days later,the level of HBSAb,IL-4,IL-10,IFN-γ,IL-2 were measured with ELISA and IL-21and FoxP3 expression level and Tfh percentage of mixed lymphocytes detected. ResultsThe HBSAb level in experimental group is significantly higher than that in the control group and the survival time of skin graft is longer than that in the control group ( F =29.886,P =0.010 ; F =29.772,P =0.011).IL-2,IFN-γ are significantly higher than that in the control group( F =18.156,P =0.0020;F =90.042,P =0.003 ),but the Th2 cytokines such as IL-4,IL-10 are lower ( F =42.102,P =0.009 ; F =23.734,P =0.015 ).The expression level of both IL-21and FoxP3 are significantly higher than control group( F =9.784,P =0.048 ;F =27.883,P =0.012). ConclusionsCombination of CsA and IL-2 fusion protein can significantly enhance the immunogenicity of HBV vaccine and prolong graft survival time.It may be related to the higher expression level of IL-21and FoxP3.

BACKGROUNDVascular endothelial growth factor-C(VEGF-C) plays a critical role in tumor-induced lymphangiogenesis and contributes to lymph node metastasis.Human antigen R(HuR) is one of the firstly identified RNA-binding proteins.It can increase the stability of a variety of growth factors and cytokines and upregulate protein expression.The aim of this study is to investigate the expression of HuR and VEGF-C protein in non-small cell lung cancer(NSCLC),and explore the relationship between the expression of HuR and VEGF-C and clinicopathological factors.
METHODSHuR and VEGF-C protein levels were detected in 81 NSCLC tissues and 15 control benign pulmonary lesion tissues by immunohistochemistry method(SP method).
RESULTSIn NSCLC tissues,positive rate of cytoplasmic HuR,nuclear HuR and VEGF-C was 45.7%(37/81),82.7%(67/81) and 70.4%(57/81),respectively.There was a significant difference in positive expression of HuR and VEGF-C between NSCLC and benign pulmonary lesion tissues(P < 0.05).The expression of cytoplasmic HuR was closely related to pTNM stages,differentiation degree and lymph node metastasis(P < 0.05),but not correlated with sex,age and histological classification(P > 0.05).Furthermore,cytoplasmic immunoreactivity for HuR protein(P < 0.05) but not nuclear HuR expression(P > 0.05) was associated with high VEGF-C expression.
CONCLUSIONSCytoplasmic HuR and VEGF-C are overexpressed in NSCLC,and are related to tumor development.HuR may mediate the modulation of VEGF-C gene expression in NSCLC.

Objective To explore the outcome and prognostic factors of adult patients with Philadelphia chromosome-positive acute lymphoblastic leukemia (Ph+ALL). Methods Forty-nine newly diagnosed adult patients with Ph+ALL were analyzed retrospectively, and the treatment effect and the impact of different factors on prognosis were explored. Results In 49 patients, there were 24 males and 25 females;the median age was 38 years (range 15-77 years). Hematologic complete remission (CR), major molecular response (MMR) and complete molecular remission (CMR) rate in patients received tyrosine kinase inhibitors (TKI) plus chemotherapy were higher than those in patients received chemotherapy only (96.8 % vs. 72.2 %, χ2= 4.308, P= 0.038; 64.5% vs. 16.7 %, χ2=10.468, P= 0.001; 25.8 % vs. 11.1 %, χ2=4.250, P=0.039). With a median overall survival (OS) of 24 months (3-70 months), the 3-year OS and relapse-free survival (RFS) rates were 32.7 % and 21.4 %, respectively. The 3-year OS rate and 1-year RFS rate in TKI plus chemotherapy group were 40.3 % and 67.8 % respectively, which were higher than those in chemotherapy group (11.1 % and 11.1 %) (χ2= 12.725, χ2= 17.401, both P< 0.001). The 3-year OS and RFS rates in the allogeneic hematopoietic stem cell transplantation (allo-HSCT) group were higher than those in the group without allo-HSCT(62.5 % vs.25.7 %,χ2= 6.196,P= 0.013; 41.7 % vs. 15.0 %,χ 2= 8.032, P=0.005).The 3-year OS and RFS rates in patients achieved MMR after 2 circles treatment were higher than those in the others (45.1 % vs. 17.6 %,χ2= 5.446,P= 0.020; 28.9 % vs. 11.7 %,χ 2= 6.484,P= 0.011). Multivariate analysis showed that received TKI (HR= 0.227, 95 % CI 0.094-0.550, P= 0.001) was an independent prognostic factor for OS; received TKI (HR= 0.225, 95 % CI 0.082-0.618, P= 0.004) and allo-HSCT (HR=0.275, 95 % CI 0.077-0.983, P=0.047) were independent prognostic factors for RFS. Conclusions TKI can increase CR,MMR and CMR rates,improve outcome,and give more chance to receive HSCT.In TKI era,allo-HSCT is still the important treatment for Ph+ALL,especially for patients without MMR.
