Objective To investigate the effect of anisodamine on calbindin-D28K(CaBP) expression in the ethanol-induced brain damage in rat cerebellum.Methods2 months aged male Sprague-Dawley rats were injected intraperitoeally with ethanol,normal saline,saline+anisodamine and ethanol+anisodamine respectively for 8 d.They were evaluated with Morris water maze.The counts,average area and density of CaBP positive neurons in cerebellum were measured with immunohistochemical technique and image analytical system.Results The latency of Morris water maze was significantly longer in the ethanol group than in the others(P<0.05),while the distance was significantly longer in the ethanol group than in the saline group and saline+anisodamine group(P<0.05).There is not significant difference between ethanol group and ethanol+anisodamine group(P>0.05),but is seemed some longer.The counts,average area and density of CaBP positive Purkinje cell were all significantly less in ethanol group than in the others(P<0.05).There Pwas not significant difference among ethanol+anisodamine group,saline group and saline+anisodamine group(P>0.05) in the counts,but the average areas and density in ethanol+anisodamine group were less than those in saline group and saline+anisodomine group(P<0.05).Conclusion The ethanol can reduce the CaBP expression in the Purkinje cells of the rats cerebellum.Anisodamine can protect the rats cerebellum from it.

Objective: To evaluate the anti-tumor and side effects of activated-HLA haploidentical peripheral blood tem cells (haplo PBSCs) in the treatment of advanced refractory solid tumor patients. Methods: Forty-two patients with advanced refractory tumor, who were diagnosed in our hospital from Oct. 2004 to Oct. 2007, were enrolled in this study (all patients signed informed consent), including 12 with ovarian cancer, 9 with renal cancer, 8 with lung cancer, 8 with breast cancer, 2 with colon cancer, 2 with gastric cancer, and 1 with melanoma. The donors were healthy direct relatives of the patients; the donors' haplo-PBSCs were mobilized, collected, and activated by rhIL-2 in vitro. The clinical efficacy and side effects of haplo-PBSCs therapy were assessed by CT/PET-CT scanning, RESIST standard, KPS score, and clinical response rates, etc. Results: All 42 patients received one episode of haplo-PBSCs treatment. The progression-free survivals (PFS) were 6 months and the clinical beneficial rate (CR+PR+SD) was 73.8%. The beneficial rate of life quality was 76.2% and the KPS increased by 20 (0-30) points on average after haplo-PBSCs treatment. The patients with KIR unmatched in GVH direction had better outcomes than those with KIR matched or KIR unmatched in HVG direction (P<0.05), and the clinical beneficial rate, PFS and total beneficial rate were 94.1% vs 60.0%, (13.4±1.3) vs (8.0±0.9) months, and 89.5% vs 65.2%, respectively (all P<0.05). The donor/recipient relation as the mother/child had a better outcome than that as the father/child (P<0.05). Patients with renal cancer or ovarian cancer had better outcomes than those with other cancers, with clinical beneficial rates being 90.0% and 81.8%, respectively. Conclusion: Activated haplo-PBSCs therapy can induce non-specific anti-tumor effect, and improve the clinical symptom and life quality of advanced tumor patients.

Objective To investigate the change of genomic DNA of liver and spleen tissue for different age of the elderly,and provide the experimental data for aging-related research. Methods 35 livers and 33 spleens of autopsied samples preserved in refrigerator at-80 ℃ were divided into 3 groups according to age:age 65y to 79y,age 80y to 89y,age≥90y. The content of DNA in liver and spleen was determined by ultraviolet absorbent method. Results Compaired with age 80y to 89y (0. 310 ± 0. 286)mg/mL,the content of DNA in liver was significant higher at age 65y to 79y (1.464 ±0.488)mg/mL and age ≥90y(1.147 ±0.333)mg/mL(P<0.05);Compared with age 80y to 89y(0. 938 ± 0. 589)mg/mL,the content of DNA in spleen was significant higher at age 65y to 79y(1. 723 ± 0. 726)mg/mL and age≥90y(1. 688 ± 0. 963)mg/mL(P<0. 05). The content of DNA was significant lower in liver (0. 856 ± 0. 658)mg/mL than that in spleen (1. 414 ± 0. 852)mg/mL. Conclusion The content of DNA in human liver and spleen tissue may be decrease along with aging. The content of DNA in the group at age≥90y may be increase. There were some differences between different viscera tissue in content of DNA.

Objective To explore the effects of dexmedetomidine on peripheral blood T lymphocyte proliferation and T lymphocyte subsets of juvenile rats with splenectomy.Methods Twenty-four healthy male Sprague-Dawley rats,weighing 130-150 g,aged six weeks were enrolled in this study.Half of the rats received splenectomy to make an immunosuppressive model,then they were randomly divided into 2 groups (n=6 each): splenectomy+normal saline group (group SN) and splenectomy+dexmedetomidine group(group SD).The another half of the rats without splenectomy were randomly divided into 2 groups: normal saline group(group S) and dexmedetomidine group(group D).After one week of normal feeding,normal saline 10 ml/kg was injected intraperitoneally (ip) in groups S and SN,dexmedetomidine 50 μg/kg was injected ip in groups D and SD respectively.Two hours after the injection,blood samples were collected.MTT was utilized to examine the peripheral blood T lymphocyte proliferative capability.T lymphocyte subsets CD4+,CD8+ were determined by flow cytometry.CD4+/CD8+ was calculated.Results Compared with group S,T lymphocyte proliferative capability,the percentages CD4+,CD8+ and CD4+/CD8+ ratio were significantly decreased in group SN (P<0.05);T lymphocyte proliferative capability in group D was decreased (P<0.05),but no significant changes was found in the percentages CD4+,CD8+ and CD4+/CD8+ ratio.Compared with the group D,T lymphocyte proliferative capability,the percentages CD4+,CD8+ and CD4+/CD8+ ratio in group SD were significantly decreased (P<0.05).Compared with the group SN,T lymphocyte proliferative capability in group SD was significantly decreased (P<0.05).Conclusion Cellular immune function of juvenile rats with or without splenectomy is suppressed by dexmedetomidine,and the suppressive function is more severe in splenectomy rats than that in normal juvenile rats.
