Objective To discuss prevention and treatment of the late complications of deteniaceacal-colon continent urinary reservoir. Methods 105 patients who underwent detenia ceacal-colon con-tinent urinary reservoir were followed up for 9 -82 months(mean 40.5 months).Clinical data of these wereretrospectively analyzed. Results Late complications occurred in 25.7%(27/105) of the cases and 9were treated with operations,including difficulty with catheterization in 4 cases(3.8%),3 treated with dila-tion and 1 with efferent limb reconstruction with ileal,urinary pouch stones in 5(4.8%),4 treated with li-thotomy,urinary pouch perfotation in 1 (0.95%),treated with repair,urinary pouch superdistention in 1(0.95%),treated with reduction, single or double lateral hydronephrosis in 8(7.6%),caused by strictureof single or double lateral lower ureters in 4 (2 treated with excision lesion and anastomosis ) and by refluxin 1,1 case suffering from azotemia preoperatively worsened to uraemia treated with regular haemodialysis,hyperchloremia in 7 (6.7%),only 1 needed drugs treatment,repeated urinary infection in 11,amomg them,10 were complicated by the other complications,all treated with sensitive antibiotic. Conclusions Most ofpatients underwent detenia ceacal-colon continent urinary reservoir had good curative effects. Late complica-tions afflicting these patients mostly had immediate or mediate relations with symptomatic urinary infection.Prevention and treatment of symptomatic urinary infection can reduce the occurrence of late complications ofthis operative method,regular and adequant pouch washing and catheterization is efficient to prevention oflate complications of this operative method.

Objective To compare the infectivity between laboratory adapted human inununodefi- ciency virus(HIV-1) and primary HIV-1 isolates for different mucosal epithelial cell lines. Methods Mu-cosal epithelial cells Caco-2, T-84, HeLa and lymphocyte MT-4 were infected with laboratory adapted HIV-1 SF33 and 2 primary HIV-1 isolates (02010561, 02010141). Culture supernatant and cells were collected respectively on 3-4 days interval after virus inoculation. The former was tested for HIV-1 antigen P24 level and viral load, and the latter was tested for total viral DNA and integrated viral DNA. Results All 3 virus strains could infect MT-4 cells and integrate into their genome. Only HIV-1 SF33 could infect Caco-2 cells but could not integrate into their genomic DNA. Both HIV-1 SF33 and 02010561 infected HeLa cells but only integration of HIV-1 SF33 was detected. All the 3 HIV-1 strains infected T-84 cells but only the integra-tion of HIV-1 SF33 and 02010141 was observed. Conclusion Although laboratory adapted and primary HIV-1 strains are able to infect human mucosal epithelial cell lines, transient or productive infection estab-lished in different mucosal epithelial cells is dependent on the character of cells and virus strains.

In this paper, the domestic varieties and quality standard of Leguminosae medicinal plants used in Tibetan medicine were analyzed. The results showed that there were 36 genera and 142 species (including varieties), as well as 64 medicinal materials varieties of Leguminosae plants were recorded in relevant literatures. In relevant Tibetan standards and literatures, there are great differences in varieties, sources, used parts, and efficacy of medicinal plants. Among them, about 38.0% (including 54 species) of the endemic plants, about 25.4% (including 36 species) of the original plants have medicinal standard legal records, except 9 kinds of traditional Chinese medicine general quality standard more fairly completed, the most varieties have only description about characters, identification, etc. Therefore it is necessary to reinforce study for the herbal textual, resources and the use present situation, chemical components and biological activity, quality standard, medicinal terms specification, to promote establishment of quality standard system for variety-terminologies-sources of Tibetan medicinal plants.

This paper is in order to discussion with the composition and characteristics of Tibetan medicine plant resources, and promote the reasonable protection and utilization of the resources of Tibetan materia medica. Statistical analysis of species, distributions, and others of Chinese endemic seed plant from Tibetan medicine plants and usually used in the clinic of Tibetan medicine. The results showed that there are 523 species (25%) of Chinese endemic seed plant, belonging to 65 families and 162 genera, in about 2 000 varieties of Tibetan medicine plants recorded in relevant literatures. There are 180 Chinese endemic seed plant species (28%) belonging to 42 families and 72 genera from 625 medicine plants usually used in the clinic of Tibetan medicine. Specifically, the most of these Chinese endemic seed plant species are characteristic crude drug used in Tibetan medicine, and mainly or only distributed in Qinghai-Tibet Plateau. And a few species of them were intersected with traditional Chinese medicines (TCM) and other ethnic medicines. In addition, about 10% are listed in China Species Red List. The Qinghai-Tibet Plateau is the most abundant areas of Areal-types of the Chinese endemic seed plant. This is the biological and ecological reason formation the characteristics of Tibetan medicine plant resources. Therefore, strengthen the research of Chinese endemic seed plants used in Tibetan medicine is great significance for the reasonable protection and utilization of Tibetan medicine plant resources.

In this paper, the popular domestic varieties and quality standard of Scrophulariaceae plants used in Tibetan medicine were analyzed. The results showed that there were 11 genera and 99 species (including varieties), as well as 28 medicinal materials varieties of Scrophulariaceae plants were recorded in the relevant literatures. In relevant Tibetan standards arid literatures, there are great differences in varieties, sources, parts, and efficacies of medicinal plant. Among them, about 41.4% (including 41 species) of endemic plants, about 15.2% (including 15 species) of the original plants have medicinal standard legal records, except the medicinal materials of Scrophalaria ningpoensis, Lagotis brevituba, Picrorhiza scrophulariiflora, Veronica eriogyne general, most varieties have not completed quality standard. Consequently it is necessary to reinforce the herbal textual, resources and the use present situation investigation, the effects of the species resources material foundation and biological activity, quality standard, specification the medical terms of the plants, and promote Tibetan medicinal vareties-terminologies-sources such as the criterion and quality standard system for enriching the varieties of Tibetan medicinal materials and Chinese medicinal resources.

OBJECTIVE Vascular dementia (VD) refers to a progressive decline in memory and cognitive function caused by chronic cerebral ischemia. 2-Vessels occlusion (2-VO) has been widely used as a model of VD. Xiao-Xu-Ming decoction, a well-known traditional Chinese medicine prescrip-tion,has been widely used to treat stroke and sequelae of stroke.The present study was to investigate the mechanism of Xiao-Xu-Ming decoction(XXM) against chronic cerebral ischemia injury in rats. METHODS After XXM treatment, rats were performed a memory testing with Morris water maze and motor ability testing using prehensile test and inclined screen test.Neuronal plasticity was observed by immunofluorescent staining with MAP2 antibody. Differentially expressed proteins of rat hippocampus were analyzed by Label-free quantitative proteomics. RESULTS XXM significantly alleviated 2-VO-induced learning and memory deficits, motor ability dysfunction, and neuronal plasticity injury in rats. The mechanism might be involved in up-regulation of 39 proteins and down-regulation of 13 proteins in the hippocampus of rats after XXM treatment vs 2-VO group rats.Gene ontology and pathway analysis showed that the regulated proteins are mainly involved in oxidation reduction process, intracellular signaling cascade process, and protein catabolic process, etc. The signal pathways are mainly involved in ubiquitin mediated proteolysis and phosphatidylinositol signaling system. CONCLUSION Current findings provide new insights into the molecular mechanisms of XXM on chronic cerebral ischemia.

OBJECTIVETo investigate the expression of programmed cell death 5 (PDCD5) in tissues of normal human prostate (NP), benign prostatic hyperplasia (BPH), and prostate cancer (PCa) in order to assess the clinical role of PDCD5 in PCa.

METHODSPDCD5 expression was determined by EnVision immunohistochemical staining in formalin-fixed and paraffin-embedded specimens obtained from 12 subjects with NP, 22 with BPH, and 22 with PCa. In addition, PCa cases were classified as low/middle-risk (Gleason sum < or = 7) and high-risk (Gleason sum >7) on the basis of Gleason grade. Positive expression rates and intensity of PDCD5 protein were observed under light microscope and analyzed with computer imaging technique. Expression of PDCD5 was compared among different prostatic tissues.

RESULTSThe expression of PDCD5 was significantly lower in tissue of PCa than in tissues of NP and BPH (P<0.01). However, there was no significant difference in PDCD5 expression between tissues of NP and BPH. In addition, the expression of PDCD5 was further downregulated with the increase of Gleason sum in PCa.

CONCLUSIONSBy downregulating apoptosis, low PDCD5 expression may play an important role in the occurrence and development of PCa. PDCD5 is supposed to have a potential clinical value to be a new predictor of progression and target of gene therapy in PCa.
