Objective:To investigate frequencies of microsatellite instability(MSI)and loss of heterozygosity(LOH)in renal ceil carcinoma(RCC),and to discuss the relationship of clinicopathological characteristics of RCC with MSI and LOH. Methods:Twelve microsatellite markers located at chromosomes 3p,9p and 14q were selected to investigate microsatellite alterations(MSI and LOH)in 31 RCC specimens and their paired metastasis specimens by polymerase chain reaction- polyacrylamide gel elect rophoresis-ethylene dibromide(PCR-PAGE-EB)staining and sequencing.Results:The frequency of MSI could reached 61.3% and that of LOH could reach 54.8%.The highest frequency of MSI was at locus of D9S168(32.3%);the highest frequency of LOH was at locus of D3S1289(21.4%).No correlation was found between MSI or LOH and the patients' age,sex,pathology type and metastastis,except that MSI was correlated with TNM stage of RCC(P

OBJECTIVETo investigate the inhibitory effect of bone marrow mesenchymal stem cells (BMSCs) on E coliinduced prostatitis in rats.

METHODSBMSCs were isolated, cultured and amplified by the attached choice method. Fifty SD rats were randomized into five groups of equal number: normal control, acute bacterial prostatitis (ABP) , chronic bacterial prostatitis (CBP), ABP + BMSCs, and CBP + BMSCs, and the animals in the latter four groups were injected with E. coli into both sides of the prostate under ultrasound guidance for 1 - 14 days to induce ABP and for 4 - 12 weeks to induce CBP. The control rats were injected with the same amount of PBS. Two weeks after injection of BMSCs into the prostates, pathomorphological changes in the prostate were observed under the light microscope and the mRNA and protein levels of IL-1β and TNF-α determined by RT-PCR and ELISA, respectively, followed by statistical analysis with SPSS 18.0.

RESULTSHistopathological evaluation showed typical pathological inflammatory changes in the prostates of the rats in the ABP and CBP groups, including glandular structural changes, interstitial edema, inflammatory cell infiltration, and fibrous hyperplasia, which were all remarkably relieved after treated with BMSCs. The mRNA and protein levels of IL-β ([0.829 ± 0.121] and [271.75 ± 90.59] pg/ml) and TNF-α ([0.913 ± 0. 094] and [105.78 ± 19. 05] pg/ml) in the ABP and those of IL-1β ([0. 975 ± 0. 114] and [265. 31 ± 71. 34] pg/ml) and TNF-α ([0. 886 ± 0. 084] and [107. 45 ± 26. 11 ] pg/ml) in the CBP groups were significantly higher than those in the control rats ([0. 342 ± 0.087] and [45.76 17. 99] pg/ml, P <0. 05); ([0.247 ± 0.054] and ([19.42 ± 7. 75] pg/ml, P <0. 01) as well as than those in the ABP + BMSCs ([0. 433 ± 0. 072] and [51. 34 ± 22. 13] pg/ml, P < 0. 05 ) ; ( [0. 313 ± 0. 076] and [28. 38 ± 8. 78] pg/ml, P < 0. 01) and the CBP + BMSCs group ([0.396 ± 0.064] and [56.37 ± 21.22] pg/ml, P <0.05); ([0.417 ± 0.068] and [29.21 ± 10.22] pg/ml, P <0.01).

CONCLUSIONInjection of BMSCs can reduce E coli-induced prostatic inflammation reaction, which.may be associated with its reduction of inflammatory cell infiltration and the expressions of IL-1β and TNF-α in the prostate tissue.

When looking back to the literature regarding insomnia, it is believed that "disharmony of stomach leads to insomnia" is an important mechanism for the attack of insomnia. This theory is widely accepted in clinical practices by ancient and modern acupuncturists, thus the method treating insomnia from the stomach is developed. But deeper research on its mechanism is still lacking. Through correlation between stomach meridian and heart meridian, spleen and stomach being the pivot of rise and decline of qi movement and yin-yang and being the pivot of five zang-viscera housing spirit, modern abdomen-brain theory and experimental research, the mechanism of treating insomnia from the stomach is discussed in this paper, so as to be better to guide clinical acupoint-selection and treatment.

Objective To observe the impacts of the method of fortifying the spleen and supplementing Qi on the cellular immunity of chronic hepatitis B virus(HBV)carriers.Methods Asymptomatic HBV carriers group(ASC group,n=60)with HBV DNA positive were randomly divided into Fortifying the Spleen and Supplementing Qi decoction group(A group,n=30)and conventional treatment group(B group,n=30),the peripheral blood T lymphocyte subsets were detected with flow cytometey and compared with those of the healthy people(The normal control group,n=18).All the patients were treated,and 24 weeks after treatment the indexes were measured again.Results As compared with those of normal controls,the numbers of CD4+ T cells and CD8+ T cells were decreased significantly in HBV carriers(P＜0.01);There was a statistical significance between the values before and complete the treatment with the decoction of fortifying the spleen and supplementing Qi(P＜0.05 or P＜0.01),and compared with conventional treatment group,there Was a statistical significance(P＜0.05).Conclusion T-cell subset function was disturbed in the HBV carriers.The method of fortifying the spleen and supplementing Qi could improve the cellular immunity of carriers with chronic hepatitis B.

A two-step method for the purification of blocking-type anti-human CD80 monoclonal antibody 4E5 from mouse ascites was developed using anion exchange and gel filtration in combination. The ascites was first purified by anion exchange after centrifugation and filtration. The experimental parameters of sample loading and elution were optimized. The optimized loading condition was pH 8.0,50 mmol/L Tris-HCl and satisfactory results were obtained using a 0~0.5mol/L NaCl step elution. The fraction containing the protein of interest was directly loaded on gel filtration column and eluted using a 20 mmol/L phosphate buffer at pH 7.2. The purity of the obtained monoclonal antibody was up to 95% with a recovery of 61%. The purity of mAb could efficiently inhibit the growth of Daudi cells. The amplification of the method was also studied using a Bio-Scale Q5 column and the result was satisfied.
