AIM： To investigate the distribution pattern of lymphatic vessels and microvessels in sporadic colorectal carcinoma （SCRC） and their relationship to metastasis and prognosis. METHODS： The lymphatic vessel density （LVD） and microvessel density （MVD） in tumor tissue obtained from 132.patients with primary SCRC, including 74 with metastases and 58 without metastases, were evaluated by immunohistochemistry using antibodies directed against D2.40 and yon Willebrand factor （vWF）. RESULTS：（1） The lymphatic vessels and microvessels at central portions of SCRC often had a reticular architecture with numerous tiny and ill-defined lumina, while those at tumor borders had large and open lumina. The LVD and MVD were both obviously higher in colorectal cancer patients with metastases than in those without （P 〈 0.001）. （2. For each one lymphatic vessel increased, there was a 1.45-fold increase in the risk of metastasis in SCRC. The specificity and sensitivity of LVD in predicting metastasis or non-metastasis in SCRC were 71.62. and 56.90%, respectively, and the corresponding LVD was 5. For each one microvessel increased, there was a 1.11-fold increase in the risk of metastasis in SCRC. The specificity and sensitivity of MVD were 66.2.% and 51.72., respectively. （3） Double labeling immunohistochemistry showed D2.40 immunoreactivity to be specific for lymphatic vessels. （4） Univariate analysis indicated that high LVD, high MVD, as well as co-accounting of high LVD and high MVD were associated with patient＇s poor disease-free survival （Puni 〈 0.05）; multivariate analysis indicated that co-accounting of LVD and MVD was an independent prognostic factor of colorectal cancer, CONCLUSION： D2.40 is a new specific antibody for lymphatic endothelial cells. Lymphogenesis and angiogenesis are commonly seen in SCRC, especially at tumor borders. The detection of LVD and MVD at tumor borders may be useful in predicting metastasis and prognosis in patients with SCRC, and, in particular, coaccount

The proton induced X-ray emission (PIXE) is used to determine the chemical ingredients of seven main elements in the samples of Ru Guan porcelain glazes and Ru Civil porcelain from Qingliangsi kiln in Baofeng County and the samples of celadon glaze from Zhanggongxiang kiln in Ruzhou City. The PIXE data are then analyzed by scatter analysis and fuzzy cluster method for determining their classification and provenance. The results show that there are obvious differences between the ingredients of glaze material of Ru Guan porcelain and Ru Civil porcelain from Qingliangsi kiln, of which the former ingredients are stable and its source is localized, and that the sources and ingredients of the glaze of Ru Guan porcelain and those of celadon glaze from Zhanggongxiang kiln are not wholly the same, of which the latter sources are much scattering.

In order to investigate the influence of organic groups on the types of organoarsenic polymolybdates, o-nitrophenylarsonic acid was reduced to o- aminophenylarsonic acid and then it reacted with sodium molybdate at pH = 3;. Three new salts were prepared and characterized:（ 1 ）（CN3H6）4[（o-NH2.6H4As）2.o6O2.], （ 2.） Cs4[（o-NH2.6H4As）2.o6O2.], （3） [（CH3）4N]4[（o-NH2.6H4As）2.o6O2.].2.2.. The IR, UV spectra, thermal properties and electrochemical behaviors are reported. It is strange enough that when the o-nitro group was reduced to o-amino group, [（RAs）2.o6O2.]4- type of complexes was formed.

Euglena gracilis 2.7, a unicellular green alga, demonstrated remarkable ability to transport Nd3+ to the cell compartments. For a given amount of Nd3+ and cells, the results of ICP-AES indicated that the cellular uptake of Nd3+ was independent of Nd3+ concentration in thebulk solution. The average uptake of Nd3+ per celi (mMd) is proportional to a parameter ξ-theratio of neodymium content to the celi counts of the system. A novel approach for probing cellular neodymium by tetraiodotetra chlorofluorescein (I4TCF) has been devised. Data derived from the cryosections of !4TCF-Nd3+ stained cells and EDAX of the fast freezing ultrathin cryosections indicate that Nd3+ is distributed over the celi compartments. Chloroplasts are the major compartments as the residence of Nd3+ in the alga. The transport should be against a concentration gradient of Nd3+ on the order of five, even higher. it is proposed that a calcium ion channel would play an important role in the Nd3+ transportation.
