AIM: To explore the localization and semi-quantification o f the glo merular complement C5b-9 complexes and synthesis of some inflammatory mediators or cytokines such as nitric oxide (NO) and tumor necrosis factor ?(TNF?) in the ra ts with anti-thymocyte serum nephritis(ATSN). METHODS: The animal mo del of rat AT SN was reproduced by a single intravenous injection of anti-thymocyte serum (ATS ). Then, the deposits of glomerular C5b-9 complexes were localized and quantifie d by immunohistochemical staining and microscopic image scanning separately. And the glomerular mesangial cells (MC) surrounded by C5b-9 complexes were counted under microscope. In addition, the expression of glomerular MC inducible NO synt hase(iNOS) mRNA and excretion of urinary NO metabolite ( NO - 2/NO - 3 ) and TNF ? in the rats with ATSN were detected. RESULTS: The MC in t h e rats with ATSN emerged necrosis followed by a rapid proliferation. In the early time of MC injury, the C5b-9 complexes were mainly seen in glomerular mesangium and MC sur fac e. But with the progression of ATSN, the MC enclosed by C5b-9 appeared gr adual decrease. Moreover, the expression of MC iNOS mRNA in early stage of ATSN obviously increased and the excretion of urinary NO - 2/NO - 3 and TNF ? also significantly increased. However, the changes of parameters mentioned abov e in ATSN proliferative stage (after 7 days) alleviated gradually. CONCLUSION: The second ary lysis of MC has relation to the deposition of C5b-9 complexes and synthesis and release of NO and TNF ? in rats with ATSN.

Objective To investigate the effects of N-acetylcysteine (NAC) on the expression of transforming growth factor-β1 (TGF-β1) in renal cortex of diabetic nephropathy rats.Methods A rat model of DN was established.The rats were randomly divided into control group,DN group and NAC group.After 8 weeks treatment,urinary albumin excretion rate (UAER) was determined.The expression of TGF-β1 in renal cortex was detected by immunohistochemistry and RT-PCR analysis.Pathomorphological changes of renal cortex were observed.Results (1)The levels of UA ER were significantly higher in DN group and NAC group [(1268.3±297.5) μg/24 h and (315.9-±86.8) μg/24 h] than in control group [(31.2±8.9) μg/24 h,q-29.85,16.76,both P＜0.01].The groups of DN and NAC versus group of control showed the increased levels of activity of TGF-β1 in renal cortex [immune-histochemistry index of glomerular mesangial area:7.35±1.17 and 3.87 ± 0.71 vs.1.95±0.34,q= 10.75,5.82,both P＜0.01];immune-histochemistry index of renal tubulointerstitium [21.21± 3.78 and 10.67±1.86 vs.3.62±0.79,q=15.20,11.36,both P＜0.01];the expression of mRNA in renal cortex[0.72±0.06 and 0.45±0.05 vs.0.23±0.04,q=9.13,7.45,both P＜0.01].The pathomorphological changes were significant in DN group and NAC group.(2)The NAC group versus DN group showed a decreased levels of UAER (q=8.17,P＜0.01),activity of TGF-β1 in renal cortex [immune-histochemistry index of glomerular mesangial area:q= 4.97,P＜0.01]immune-histochemistry index of renal tubulointerstitium (q = 6.86,P ＜ 0.01 );the expression of mRNA in renal cortex (q= 3.69,P＜0.05) and showed improvement of pathomorphology in renal cortex.(3) There was a significantly positive correlation between expression quantity of TGF-β1 mRNA in renal cortex and UAER level in NAC group(r= 0.749,P＜0.05).Conclusions The protective effects of NAC on the kidney of DN rats may be partly related with inhibition on the expression of TGF-β1.

Objective: To study the correlation between MR perfusion imaging and pathology after transcatheter arterial chemoembolization (TACE) using VX2 liver cancer model and to provide a theoretical basis to evaluate the curative effect of TACE. Methods; Fifteen New Zealand white rabbits (weight: 2.5-3.0kg) were randomly divided into three groups, with 5 in each group (group 1, pre-TACE; group2, 3 days after TACE; group 3,1 week after TACE). The rabbit VX2 hepatic carcinoma models were presented in all rabbits. All of the three groups received TACE at three weeks after the tumor was implanted. The MR perfusion imaging was performed before chemoembolization, at 3 days and 1 week after chemoembolization respectively for group 1, 2 and 3. Each animal was then sacrificed for pathology observation after MR examination. Results: The lesions assessed before TACE were hyperintense compared with the surrounding liver parenchyma on DWI images. The volume of neoplastic cells became large. Nucleus was hypertrophic with different size and shape. Phase of nucleous mitosis showed in many cells and necrosis was hardly seen. No obvious difference was found between the peripheral area and the core area. At 3 days after TACE, the heterogeneous hypo-intense was observed on DWI images. Many nuclear fragmentation and caryolysis appeared on pathology. Neoplasm necrosis was seen. At 1 week after TACE, the heterogeneous hypo-intense areas became larger. Light microscopy showed incomplete necrosis. There were increased karyopycnosis and nuclear fragmentation. Conclusion: MR perfusion imaging of VX2 liver cancer corresponds well with pathology and can reflect the outcome of liver cancer after TACE.

Objective To establish the methods for quantitating the circulating tumor DNA with PicoGreen fluorescent nucleic acid stain and investigate the role of the quantitative analysis in diagnosis of breast cancer. Methods Circulating tumor DNA was isolated from serum with QIAmp blood kit and was quantitated by spectrofluorometry with PicoGreen fluorescent stain. Receiver operator characteristic ( ROC) curve and area under the curve were used to estimate the role of DNA quantification in diagnosis of breast cancer. Results The efficiency of QIAamp blood kit isolating DNA from serum was 37. 8%-46. 2%, average 43. 4%. Circulating tumor DNA concentration as low as 1 ng could be detected by PicoGreen spectrofluorometry. and the detected range was 1-500 ng/0. 2 ml. The median concentration of serum DNA in breast cancer group was (169. 70+ 124. 10) μg/L, and that of healthy control and breast benign group were (54. 30±36. 84) μg/L and (51. 70±29. 04) μg/L, respectively (P<0. 01). The area under the ROC curve was 0. 899 (95% CI: 0.848-0.951), and the sensitivity was 78. 2%, the specificity was 90% by using the cutoff value of 96. 0 ng/ml. Conclusions The concentration of circulating tumor DNA can be efficiently quantitated by PicoGreen spectrofluorometry, which indicates the potential of clinical applicability in breast cancer diagnosis.
