Objective To evaluate the palliative effect on pain relief in patients with multiple bone metastases treated with 89SrCl2 together with Sodium Ibandronate,Sodium Ibandronate alone and 89SrCl2 alone. Methods Eighty-four patients with bone pain secondary to bone metastases were divided into three groups. Thirty patients were treated with combined 89SrCl2 and Sodium Ibandronate,26 with 89SrCl2 alone and 28 with Sodium Ibandronate alone. The x2 test was used in data analysis. Results The overall palliative pain relief rate in the combined treatment group was 96.6 % (29/30). For the groups using Sodium Ibandronate or 89SrCl2 only,the palliative rates were 71.4% (20/28) and 73.1% (19/26),respectively. There are statistically significant differences between the combined treatment group and the other 2 groups with single treatment modalities in the overall palliative pain relief rate (x2 = 7.497 ),in terms of improvement in (1) whole body Karnofsky performance status (KPS) score (80.0% (24/30) vs 50.0% (14/28)/53.8% (14/26),x2 =35.476) and (2) focal palliative rate (47.6% (50/105) vs 11.2% (11/98)/22.2% (20/90),x2 =6. 564,all P ＜ 0. 05 ). Conclusions Combined treatment with 89 SrCl2 and Sodium Ibandronate is more effective than single treatment modalities to relieve bone pain seccondary to multiple bone metastases.

Objective To investigate the blockade effects of soluble PD-1 (sPD-1) expressed in vivo on B7-H1/PD-1 signal transduction,and inhibitory effect in pulmonary metastasis of melanoma with combi- nation of Hsp70-B16 antigen peptides in mice.Methods The pulmonary metastasis model of melanoma was established in mice.Immunohistochemical staining and flow cytometry were utilized to detect the expres- sion of PD-1 and B7-H1 respectively in pulmonary metastasis loci.Four days after the inoculation of tumor cells,forty murine models of pulmonary metastasis were randomly divided to be immunized with normal sodium (group A),empty vector pcDNA3.1 (group B),PDlA plasmid (group C) respectively via tail vein injection,subcutaneous injection of Hsp70-B16 antigen peptides (group D) or with the combination of intra- venous PDlA plasmid and subcutaneous Hsp70-B 16 antigen peptides (group E).The local infiltration with lymphocytes in pulmonary metastasis loci was observed and a series of immunological parameters were assessed 17 days after the inoculation of tumor cells.Results The melanoma pulmonary metastasis model was successfully established.There were a lot of PD-1 positive cells in these loci,and B7-H1 molecule was massively expressed on the surface of B16 cells in metastasis loci.The pulmonary metastasis was inhibited in the mice of group E,and the inhibition rate was 95%,higher than that in other groups (53%,76%,9% in group C,D,B,respectively).The quantity of CD8~+ T cells in pulmonary metastasis loci,cytotoxicity of spleen lymphocytes to tumor cells,and serum concentration of IL-2 and IFN-?were all significantly elevated in the mice of group E as compared with those of other groups (all P

AIM: To measure the macular thickness of normal young people by 3D 1000 optical coherence tomography (OCT) and study the repeatability of measuring results and the relationship between the thicknesses of macular and gender. At the same time, to compare our result with the data of other types of OCT, and to understand the consistency of the measuring results of macular thickness of different types of OCT.

OBJECTIVETo investigate the sociopsychological basis of hypertensive disorder in pregnancy (HDP) and explore a new pathway for etiological study of HDP.

METHODSA prospective investigation was conducted in 1154 women in second trimester pregnancy and 9 factors were surveyed using Olson marital quality questionnaire (ENRIC). The discrepancy between the norms and factor scores of ENRIC was analyzed, and the scores of ENRIC were compared between normal gravidas and patients with HDP. The correlation between ENRIC scores and the severity of the condition was also evaluated.

RESULTSThe score of the 1124 gravidas for marital satisfaction was significantly higher than the norm (P<0.05), but the scores for relationship with relatives and sexual life were significantly lower (P<0.05). The other 6 factors had similar scores with the norms (P>0.05). Patients with HDP had significantly lower scores for 7 factors than the normal gravidas (P<0.05), but had comparable scores for financial arrangement and sexual life (P>0.05). The severity of HDP was not found to associate with variation of the scores for the 9 factors (P>0.05).

CONCLUSIONSMarital quality is an important social and psychological basis of HDP, and this study provides some evidence for the social and psychological investigation of the etiology of HDP.

OBJECTIVETo explore the prognostic impact of bone marrow involvement (BMI) and therapy in diffuse large B cell lymphoma (DLBCL).

METHODSThe clinical characteristics and prognosis of 83 DLBCL patients with or without BMI were retrospectively analyzed. The treatment outcome of standard CHOP regimen (CHOP group), intensive-dose regimen (intensive-dose group) and rituximab combined therapy (rituximab group) were compared.

RESULTSThe adverse prognostic factors including LDH elevation, ECOG score > or =2, higher IPI and aaIPI score, B symptom, hepatomegaly, splenomegaly, hemoglobin <110 g/L, platelet <100 x 10(9)/L and serum albumin <35 g/L were more prevalent in DLBCL patients with BMI than in those without BMI. Multivariate analysis showed that BMI was an independent prognostic factor of DLBCL. The 3-year OS and PFS rates in rituximab group were 78.1% and 64.3%, respectively, being statistically higher than that in CHOP group (23.6% and 21.8% respectively, P = 0.000 for both) and in intensive-dose group (33.3% and 25.7% respectively, P = 0.002 and 0.001, respectively). But no difference between the latter two groups (P = 0.411 and 0.694, respectively). For the patients with BMI, the 3-years OS and PFS in rituximab group (57.1% and 57.1%) were statistically higher than that in CHOP group (13.9% and 14.1%) and intensive-dose group (29.5% and 16.8%) (P = 0.029 and 0.012 respectively), respectively and also no difference in the latter two groups (P = 0.226 and 0.376 respectively). In the rituximab group, the 3-years OS and PFS were 86.7% and 67.3% respectively in patients without BMI, being higher than that in patients with BMI (57.1% and 57.1%), but the difference was not statistically significant (P = 0.645 and 0.965 respectively).

CONCLUSIONBMI is a negative independent prognostic factors of DLBCL patients. The rituximab combined chemotherapy can significantly improve the therapeutic effect of the DLBCL, and relieve the negative impact of BMI.

OBJECTIVETo investigate the feasibility that transforming growth factor-beta1 (TGF-beta1) -loaded fibrin sealant (FS) promotes bone marrow mesenchymal stem cells (BMSCs) to create tissue engineering cartilage in vivo.

METHODSThe BMSCs were isolated from healthy human and amplified in vitro, and then induced by defined medium containing TGF-beta1 and dexamethasone. After 7 days the induced BMSCs were collected and mixed with TGF-beta1-loaded FS or FS as BMSCs+ FS-TGF-beta1 group and BMSCs+ FS experimental group. Then the mixture was injected by a needle into the dorsum of nude mice. In control group, only FS or BMSCs were injected. The tissue engineering specimens were harvested from nude mice 12 weeks later. Gross observation, average wet weight measurement, glycosaminoglycan (GAG) quantification, histology and immunohistochemistry were used to evaluate the results.

RESULTSThe BMSCs have possessed the shape and functional characters of chondrocyte when transferred to a defined medium. After injection of the mixture, the cartilage-like tissue were formed in two experimental groups. Compared with BMSC+ FS group, the specimens of BMSCs +FS-TGF-beta1 group were larger and firmer. Alcian staining showed better metachromatic matrix formation. The GAG contents were significantly higher. Immunohistochemical staining of collagen type II was stronger. However, no cartilage-like tissue was formed in two control groups.

CONCLUSIONTGF-beta1-loaded FS can promote BMSCs to contract injectable tissue engineering cartilage in vivo.

OBJECTIVETo explore the possible negative regulatory elements induced by the treatment of experimental murine hepatoma with 4-1BBL, and to investigate the synergistic effects and mechanisms of 4-1BBL and soluble PD-1 (sPD-1) in tumor therapy.

METHODSMice were inoculated intramuscularly (i.m.) with 5 x 10(5) H22 tumor cells in the right hind thigh to establish the experimental hepatoma model. The mice were randomly divided into 5 groups (12 mice in each group) after inoculation. The mice of group A, B, C and D were injected with NS, plasmid pcDNA3.1, plasmid p4-1BBL and plasmid pPD-1A respectively. The mice in group E, the combinatorial treatment group, were injected with plasmid p4-1BBL and pPD-1A together. Then the anti-tumor effects, using the tumor growth rates and mice survival rates and others as parameters, were recorded. Meanwhile, the phenotype of lymphocytes and residual tumor cells in the peri-tumor tissue were analyzed.

RESULTSEither transfection with 4-1BBL gene alone or with sPD-1 alone could inhibit tumor growth to some extent, but a more significant anticancer effect was obtained in the combinatorial treatment group (group E), in which the tumors were completely inhibited in 42% of the mice, compared with 0 in the other groups. In addition, the survival rate of mice in group E was 100%, compared with 30% in group B, 65% in group C and 62% in group D. The FACS analysis results showed that the expression level of B7-H1 and B7-DC on residual tumor cells in group C (injected with p4-1BBL alone) was higher than that on cells in other groups. The amount of CD8+ T cells in the peri-tumor tissue of group E was significantly increased.

CONCLUSION4-1BBl can induce an up-regulation of negative regulatory elements and at the same time it can enhance the anti-tumor response. The combinatorial treatment with 4-1BBL and sPD-1 can produce a positive synergistic anti-tumor effect on our murine experimental hepatoma.
