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 elucidates the effects of HPV18 E6 siRNA targeting at human papillomavirus(HPV)18 E6 gene on the proliferative activity of HeLa cells and chemotherapy sensitivity.Methods HPV18 E6 expression of HeLa cells was inhibited by siRNA interference,the change of P53 and P21 proteins expression level was measured by Western blot.MTT assay was used to detected proliferative activity and sensitivity to paclitaxel liposome of HeLa cells.Results After inhibition of E6 expression,P53 and P21 proteins increased and the growth of HeLa cells was decreased(P ＜0.01).The inhibition rate of HeLa was markedly increased after transfection of HPV18 E6 siRNA and paclitaxel liposome.Conclusion HPV18 E6 siRNA can effectively silence gene expression of E6 and inhibit proliferation of HeLa cells.HeLa cells are more sensitive to combine HPV18 E6 siRNA with paclitaxel liposome than that of control groups.

Objective To investigate the possibility and surgical effect of simultaneous tympanoplasty to chronic suppurative otitis media in the period of infection. Methods Forty-eight cases (48 ears) with chronic suppurative otitis media in the period of infection (31 with cholesteatoma, 17 with caries) were underwent simultaneous Wullstein Ⅱ and Ⅲ tympanoplasty on the complete elimination of the lesions (typical or modified mastoidectomy). Results All eases had dry ears within 4-10 weeks with average of 7 weeks. The air-bone gap within 10 dB was in 11 eases, 15 to 20 dB in 25 cases, 25 to 30 dB in 9 eases, no change or worse in 3 eases. Conclusions Infection is not the absolute eontraindication to the tympanoplasty in treating chronic suppurative otitis media, Wullstein Ⅲ tympanoplasty plus mastoid cavity obliteration and eonchaplasty is a suitable choice to treating chronic suppurative otitis media on the complete elimination of lesions and reconstruction of the ventilation system among mastoid cavity, tympanum and eustachian. The malfunction of eustachian is the main eanse to failure of surgery.

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.
