Objective To investigate the clinical value of 125I particle implantation brachytherapy combined with intermittent hormonal therapy for treating clinical moderate and high risk non-metastatic prostate cancer.Methods A prospective study was proceeded and 100 cases with moderate and high risk (cT≥T2b,Gleason score ≥ 7,pre-biopsy PSA ≥ 10 ng/ml)non-metastatic prostate cancer were included.The selected patients were divided into two group.In the study group,patients were treated with 125I particle implantation combined with intermittent hormonal therapy.In the control group,patients were treated with only intermittent hormonal therapy.Hormonal therapy was maximal androgen blockage for two groups,including bicalutamide 50 mg oral every day and Leuprorelin 3.75 mg subcutaneous injection every 28 days.There were 50 cases in each group and clinical trial agreements were signed.During follow-up,PSA were tested every month.Chest X-ray and whole-body hone scanning were checked every 6 months.Hormonal therapy was stopped when patient's PSA level fell to 0.2 ng/ml,and keep stabilized for 3 months.When PSA level elevated for 3 times continuously and over 1 ng/ml,hormonal therapy was initiated again.The IPSS scores were documented before treatment and every 3 months after treatment.Adverse reactions of urinary tract and rectum were assessed every 3 months after 125I particle implantation in study group.The ratio of the first time to stop hormonal therapy,the time duration of first hormonal therapy and stable phase,re-hormonal therapy free survival rate,bone metastasis free survival rate,castration resistance prostate cancer(CRPC) free survival rate,cancer-specific free survival rate and overall survival rate were compared.Results The 100 cases in this study were followed up for 24-40 months,with an average time of 31.6 months.In study group,the PSA level in all cases descended to the level of stopping hormonal therapy.The time duration of hormone therapy ranged from 4 to 12 months,with an average time of 6.3 months.21 (42％) cases had a PSA elevation again to restart hormonal therapy.In control group,the PSA level in 47 cases descended to the level of stopping hormonal therapy.The time duration of hormone therapy ranged from 5 to 15 months,with an average time of 7.2 months.34 (68％) cases had a PSA elevation again to restart hormonal therapy.There was no significant difference in percentage of cases of stopping hormone therapy and in time duration of hormonal therapy for the first cycle.Instead,there were significant differences in stable phase after first cycle hormonal therapy between two groups (27.2 months vs.17.7 months;P ＜ 0.001).When analyzed by Kaplan-Meier survival curve,there was no significant difference in cancer-specific survival rate and overall survival rate.There were significant differences in Re-hormonal therapy free survival (P =0.002),bone metastasis free survival (P =0.04) and CRPC free survival(P =0.005).Conclusions Compared with intermittent hormonal therapy alone,125I particle implantation brachytherapy combined with intermittent hormonal therapy could prolong the hormonal sensitive time in moderate and high risk nonmetastatic prostate cancer patients and control the progress of the prostate cancer.

Objective To investigate the gray matter volume differences between adult hypothyroid subjects and healthy controls using voxel-based morphometry (VBM).Methods A total of 28 untreated hypothyroid patients and 28 age and gender-matched uormal controlswere recruited.The coucentrations of their freetriiodothyronine (FT3),free theroxine (FT4),and thyroid stimulating hormone (TSH)were testedfrom their venous blood on the day they accepted MR scanning.High resolution 3D-datawereobtained using 3.0 T MRI scanner.VBM analysis was performed to detect the volume differences between the groups by using voxel-wise two sample t test.Multiple regression analysis was employed to analyze the influence exerted upon gray matter volume by serum FT3,FT4,and TSH concentrationof hypothyroid patients.Results Compared to controls,gray matter volumes in the bilateral superior frontal gyri,left precentralgyrus and bilateral cerebellum were decreased in hypothyroid patients (voxels 211-2 142,t=3.36-3.69,P＜0.01,corrected).No significant correlation between the gray matter volume in the above-mentioned brain regions and the clinical variables (serum FT3,FT4,and TSH concentration) (P＞0.05) was found in the multiple regression analysis.Conclusions VBM analysis revealed that hypothyroid patients exhibited reduced gray matter volume in multiple brain regions.It suggests that the lack of thyroid hormones can lead to the structural abnormalities in adult brain and selective gray matter atrophy in multiple brain regions.

To observe the clinical effect of Yisui decoction plus western medicine in treating multiple system atrophy patients, totally 65 patients from China-Japan Friendship hospital during 2008-2012 with complete clinical data and received consecutive traditional Chinese medicine and western medicine treatment for more than 3 months were observed changes of traditional Chinese medicine symptom score, part 1 of unified multiple system atrophy rating scale, orthostatic hypotension before treatment and after 3 months treatment. After 3 months treatment, total effective rate of traditional Chinese medicine symptom was 70.8%. Compared with before treatment, score of part 1 of unified multiple system atrophy rating scale was obviously reduced after 3 month treatment (P < 0.001). Ex- cept swallow function without significant improvement, the remaining projects of unified multiple system atrophy rating scale were im- proved obviously (P < 0.05), of which the most obvious differences were orthostatic symptoms, falls and intestinal function (P < 0.001). Orthostatic hypotension after 1 month treatment and 3 month treatment was obviously better than before treatment (P < 0.001). There was no significant difference in orthostatic hypotension between 1 month treatment and 3 month treatment. The research results show that Yisui decoction plus western medicine has a certain effect on improving clinical symptoms of multiple system atrophy patients, especially has a significant effect on orthostatic hypotension, and can maintain a stable clinical effect in a certain period of time.

Objective To elucidate the immunologic mechanism and clinical effect of high intensity focused ultrasound (HIFU) combined with dendritic cell and cytokine induced killer cell (DC-CIK) immunotherapy on patients with pancreatic cancer.Methods Seventy-two pancreatic cancer patients were divided randomly into 2 equal groups,one treated with HIFU only the other treated with HIFU and DC-CIK immunotherapy.Ultrasound imaging and a variety of immunological indexes were recorded before and after treatment and the clinical effects in the two groups were compared.Moreover,autogenous tumor cells were isolated from the combination therapy group and the killing activity of DC-CIK which loaded tumor antigen processed by HIFU on autogenous tumor cells was observed.Results Tumor antigen processed by HIFU can improve the killing activity of DC-CIK on autogenous tumor cells.After treatment,the immunological indexes,of all patients were better than before treatment.(58.26 ± 17.97 versus 52.15 ± 14.22 pg/ml with IL-12 22.14 ± 6.39 versus 17.36 ± 5.73 ng/ml with HSP70 and 0.94 ± O.34 versus 1.32 ± O.61 ng/ml with TGF-β,P ＜ 0.05 ) ; The combination group was significantly better than the HIFU group with regard to the average scores of quality of life (75.89 ± 19.65 versus 67.22 ± 16.34,P＜0.05),pain (3.15 ±0.82 versus 3.59 ± 1.04,P ＜0.05),tumor markers (107.55 ±27.58 versus 123.63 ±34.12 U/ml) and survival time (18.92±6.47 versus 13.36 ±5.78 mos).Conclusion HIFU can improve the immunologic status and anti-tumor response in patients with pancreatic cancer.HIFU combined with DC-CIK has good synergistic therapeutic effect for treating pancreatic cancer.

This study aimed to investigate the synergistic effect of lidamycin (LDM) and rituximab on human B cell lymphoma Ramos cells. Cell proliferation was measured using MTS assay, cell apoptosis was analyzed by Annexin V-FITC/PI assay, the expression of apoptosis related proteins was analyzed by Western blotting, and the in vivo lymphoma inhibition was verified using BALB/c mice inoculated via tail vein using Ramos cells which stably expressed pEGFP-N1 plasmid. The results showed that, after the pretreatment with rituximab for 48 h, rituximab and LDM showed significantly synergistic effects on cell proliferation. Cells in combined treatment group had a higher apoptosis rate than that in LDM treatment group. Compared with the LDM treatment group, the expression of apoptosis-related proteins such as Cleaved caspase-3, Cleaved caspase-7, Cleaved caspase-9 and Cleaved PARP in combined treatment groups increased, and expression of cIAP-2 and Bcl-2 decreased. The result of in vivo experiment showed that, in the combined treatment group, the survival time of BALB/c mice was significantly longer than the mice in control group and LDM treatment group, and the degree of tumor accumulation and metastasis to lymph nodes and spleen was lower.
