Atherosclerosis obliterans of lower extremity artery mainly involve the aorto-lliac artery,femoral-popliteal artery and below-knee arteries.At present the major treatment of the disease is endovascular treatment.Due to anatomical differences between the three arteries,the principles and effect of endovascular treatment are different.The endovascular treatment of iliac- femoral lesions,because of its patency rate not lower than surgery,has become the preferred way.On account of the high incidence of femoral- popliteal lesions and the dissatisfaction for patency rate,the endovascular treatment of femoral-popliteal lesions has become a hot research.Endovascular therapy in the below-knee arteries is still in the exploration,currently a small balloon-based.

Objective To investigate the role of GYLZ-RCC18 in the generation and development of renal cell carcinoma (RCC). Methods By using SMART RACE and RT-PCR the full length of GYLZ-RCC18 was cloned and its expression was detected in RCC of different grade and stage by amplification of a special fragment sequence in the first reading frame about 504 bp. Results The full length of GYLZ-RCC18 about 3.5 kb expressed in RCC in higher level than in normal kidney tissue.GYLZ-RCC18 overexpressed in high grade and high stage RCC being 1-9 folds higher than that in low grade and low stage ones. Conclusions GYLZ-RCC18 is a new gene especially related to RCC and is closely related to the generation and development of RCC.Study of the gene will be helpful in the understanding of the molecular mechanism of the generation and development of RCC and may direct the diagnosis and treatment of RCC.

ObjectiveTo investigate the differential expression of ATF5--a novel gene fished out by yeast two hybrid from renal carcinoma library.MethodsRT-PCR and Northern blot was used to examine the expression level of ATF5 in renal cell line A498,786-O,GRC-I,293 and HK-2.The area absorbance value of ATF5 RNA was quantitative by computerized-imaging system.ResultsCompared with the controls,the expression level in renal cancer cell line(A498,786-O,GRC-I) and embryonal cell line (293)is much higher than that in the normal cell line HK-2.ConclusionsIt is indicated that ATF5 may play a significant role in the renal carcinogenesis through cross-talk with Wnt signal pathway.

Lung adenocarcinoma is usually thought to follow a linear multistep progression schema,that is precancerous lesions progress to adenocarcinoma in situ,and progress to micro-invasive adenocarcinoma,eventually some lung adenocarcinoma happen diffusion.However,recent findings reveal that this linear progression schema might not occur in all lung adenocarcinoma subtypes,and some subtypes show a kind of non-linear progression schema.The study of these two kinds of schemas can help for early detection of lung adenocarcinoma.

0.05).A total of 121 patients were involved in present study.Ninety days after treatment the BI scores of group Ⅰ,Ⅱ and Ⅲ were 63.7?12.7,62.3?13.5 and 42.6?13.1,respectively,and the significant differences existed between group I and group Ⅲ(P0.05).Compared with the baseline data,the fibrinogen of group Ⅰ and Ⅱ decreased at day 3,5 and 7(P

Objective To confirm the expression and localization of COX-2 gene in mature rat testis,as COX-2 not only plays a central role in inflammation by up-regulating the synthesis of prostaglandins,but also mediates critical reproductive functions by other mechanisms. Methods In the mature Wistar rats,COX-2 expression and its localization were examined by using immunohistochemistry,RT-PCR and Western-blot. Results The results of RT-PCR and Western-blot showed that COX-2 mRNA and its protein exist in the testis. Expression of COX-2 was localized in spermatogenic cells on immunohistochemical study.No COX-2 expression in sertoli cells and leydig cells was found. Conclusions The present study confirmed the expression of COX-2 in rat testis and its localization in spermatogenic cells.These suggest that COX-2 may play a role in spermatogenesis.

ObjectiveTo investigate the interaction pr otein with Wnt signaling molecular-TCF4 in renal carcinogenesis.Me thodsThe N terminal and DNA binding domain of human T cell factor 4 (TCF4ND, 1～495 aa) was used as a bait to screen the renal carcinoma cDNA libra r y by yeast two hybrid.Results51 positive colonies were fished out such as ?-catenin,TCF4,activating transcription factor 5(ATF5),and 2 unknown genes.ConclusionsIt is indicated that exten sive signaling cross-talks between Wnt and other signaling pathways might play an significant role in renal carcinogenesis.

It is well known that the nitrate and nitrite from environment is causally related to infant methemoglobinemia and esophageal cancer.In the past three decades,there was also much evidence to reveal that nitrite and nitrate from drinking water or diet were potentially related to human congenital malformations.The present paper introduced the exposure and transformation of nitrate,nitrite and N-nitrosocompound from environment and the evidences of investigation about relationship between these compounds and human congenital malformations.

PURPOSE To explore an efficacious therapy for liver metastasis of colorectal carcinomas. METHODS Basing on excision of primary lesions. 86 cases of colorectal carcinomas metastasize to liver were treated in four different manners, namely: sole resection of the metastasis lesions, chemoembolization-resection, sole chemoembolization. and chemotherapy. We also analyze the efficacy in curing single metastatic liver cancer, multiple metastatic cancer that is confined to one section or both left and right sections of liver. RESULTS One year survival rates in the groups of sole resection and chemoembolization-resection are better than that of sole chemoembolization P

[Objective]Discussion on academic ideas and clinical experience of Professor XIE Jingri in treatment of ulcerative colitis(active phase). [Method] From the disease affiliation, etiology and pathogenesis,syndrome differentiation, clinical adding and subtracting, disease aftercare to expound the academic viewpoints and clinical experience of Prpfessor XIE Jingri in treating ulcerative colitis(active phase), summarize his prescription regularity and treatment characteristics,and put an example to exemplify that.[Results]Professor XIE Jingri thinks that spleen deficiency is its fundamental pathogenesis,dampness-heat is the key factor of attack, the liver is closely related to the lung, spleen and large intestine,it could adjust the emotions and circulation of Qi, blood and body fluid.Therefore,we shuold take the method of strengthening spleen and nourishing Qi and dampness-heat clearing simultaneously as basic therapy, and pay more attention to the treatment lying in regulating the liver, use the method of regulating qi activity and activating circulation to remove blood stasis, focus on disease aftercare at the same time,the clinical therapeutic effect is satisfied.[Conclusion]The clinical experience of Professor XIE Jingri in treatment of ulcerative colitis(active phase) could effectively alleviate symptoms and reduce relapse rate,it is worth to be summarized and popularized.
