Objective To study the clinicopathological characteristics of complicated Kaposi's sarcoma after renal transplantation.Methods Five cases of complicated Kaposi's sarcoma after kidney transplantation were studied by histopathological immunohistochemical and ultrastructural observations.Results Of the 5 Kaposi's sarcoma patients,2 had multiple amaranthine dermal plaques starting on the legs,one had lymph node hypertrophy all over the body,and others had inguinal lymph node and adenoid hypertrophy. Histopathologically,these angiomatous lesions had characteristic areas of spindle cells within which erythrocytes were enmeshed.Admixed in these lesions were hyaline bodies and hemosider-laden,phagocytic cells.Immunohistochemical and ultrastructural studies revealed that this tumor was derived from vasofomative mesenchyme with multipotential capabilities.It was found that the epithelia and spindle cells were positive for Vimentin,CD-31,CD-34 and Ⅷ-RAg.Conclusion Complicated Kaposi's sarcoma after kidney transplantation can be diagnosed by combination of clinical manifestations and histopathological examinations with immunohistochemical and ultrastructural observations.

Lipopeptides produced by Bacillus subtilis JA antagonized a broad spectrum of fungal pathogens. Crude lipopeptides were extracted with methanol from the precipitate which was obtained by adding 6 mol/L HCl to the cell-free culture broth.The crude extract was run on Diamonsil C_(18)column(5?m,250 mm?4.6 mm) in reverse phase HPLC system to purify the lipopeptides.Inhibitory ability and IC_(50)values of lipopeptides towards various microorganisms were determined by agar diffusion method.The results showed lipopeptides exhibited strong inhibitory activity against some important plant pathogenic fungi,including R.solani and F.oxysporum.The ability of B.subtilis JA to antagonize against the growth of the post-harvest pathogen -B,cinerea was tested in vitro.Spore germination of B.cinerea was strongly inhibited in the presence of JA cell suspension.Furthermore,B.subtilis JA can produce antifungal volatiles which strongly inhibited the spore germination and mycelial growth of B.cinerea.As a biocontrol agent,the synergic effect of lipopeptides and volatiles may play a major role in controlling the pathogens by B.subtilis JA.

The expression of survivin, a member of inhibitor of apoptosis (IAP) family, was examined in bladder transitional cell cancer (BTCC) tissue and adjacent normal tissues to examine its clinical implication in the development of BTCC. Thirty specimens of bladder cancer were detected for the expression of survivin by using immunohistochemistry and real-time quantitative reverse transcription polymerase chain reaction (RT-QPCR) in BTCC tissue and adjacent normal tissues. Our results showed that the positive rate of survivin immunostaining specimen were 0 and 60% (18/30) in the adjacent normal tissues, bladder cancer, respectively. The-DeltaDeltaCT value of survivin in bladder cancer tissue was 10.2829 (9.0034-11.5624) times that in the adjacent normal tissues. The expressions of survivin were correlated with the pathological grades of tumor and clinical stages. It is concluded that there was only weak expression of survivin mRNA in the adjacent normal tissues, but the expression of survivin mRNA in bladder cancer tissue was much higher than that in the adjacent normal tissues and the expression of survivin was correlated with pathological grades and clinical stages of tumor.

BACKGROUND: External preparations treatment of fractures in traditional Chinese medidne are mostly ordinary hard-paste, cream, ointment, which lack of modernized traditional Chinese medicine transdermal delivery systems, and the treatment has poor drug absorption and simple process. The treating procedure needs to be used repeatedly, which would affect fracture external fixation and lead to unsatisfactory therapeutic effect. In this Paler, the extemal treatment of traditional Chinese medidna was combined with advanced micro-nano-technology to develop a new medical complex functional materials-micron traditional Chinese medicine functional lining material, which is an organic combination of diaplasis, fixation and local drug remedy, which provides a better treatment for fractures. OBJECTIVE: To explore the effect of micron tradifional Chinese medicine functional lining material on the healing of fracture in rabbits, METHODS: After model preparation, rabbits were randomly divided into 4 groups: rabbits in the micron group were treated with micron traditional Chinese medicine functional lining material plus plaster external fixation; those in the traditional Chinese medidna control group were treated with ordinary Chinese medicine functional material plus plaster extemal fixation; those in the lining material control group were treated with ordinary lining material added plaster extemal fixation; those in the natural healing control group had no special treatments. The effect of fracture healing was evaluated by X-ray at 2, 4 and 6 weeks after modeling. The serum concentration of alkaline phosphatase, calcium and phosphorus was detected respectivaly before modeling and at 2, 4 and 6 weeks after modeling. RESULTS AND CONCLISION: ①X-rap examination:After 6 weeks the external was almost copletly absorbed and medullary cavity was completely recanalizad in the micron group, while fracture line disappeared and the external callus began to be absorbed and medullary cavity was not recanalized in the traditional Chinese medidne control group. Additionally, there were case of non-union stump hardening in natural healing group. ②Serum biochemistry:The activity of alkaline phosphatase reached a peak after 2 weeks in micron group, which was 2 weeks ahead of time compared with that in traditional Chinese medicine control group. And the peak concentration of alkaline phosphatase in micron group was higher than other groups. After 4 weeks serum calcium concentration started to fall significantly and phosphorus concentration started to rise significantly in micron group, as was statistically significant compared with other groups. After 6 weeks serum calcium concentration in micron group had fallen to normal level, while that in other groups was higher than normal. And phosphorus concentration in micron group increased significantly, which was statistically significant compared with natural healing group. The results demonstrated that micron feature traditional Chinese medicine lining matedat can enhance the activity of alkaline phosphatase, decrease the serum concentration of calcium and increase the serum concentration of phosphorus and the product of calcium and phosphorus, therefore, promote the healing of fracture, It shows that micron traditional Chinese medicine functional lining matedal plays a stronger effect on promoting the healing of fracture than that of ordinary Chinese medicine functional lining material.
