    On the basis of researches on the shallow water facies biostratigraphy bearing conodont and on the development of Siplnmodella, this paper sums up and approaches again the division results gained in 80, s of fourteen boundary sections of shallow water facies Devonian and Carboniferous in South Guizhou, Northern Guangxi, Northern Guangdong, Central Southern Hunan, Northern Hubei, Northern Sichuan, etc. The paper suggests settingup four biostratigraphical Siphanodella sequences of shallow water facies and using Si. levis coresponding to internationally recognized Si. sulcata as the standards of boundary divisions of shallow water facies, with the first seen sequence across within the zone of Cystophrentis. The author thinks that it is better for boundary lines to be marked on the tops of Shaodong formation, Zhewang formation and their equivalent stratum formations.

    The authors report a novel immundelectrophoresis assay with hybridoma cells which secrete monoclonal antibody against lung cancer and its application in the detection of PA_3 antigen in lung cancer patients. Sera from 22 patients with lung cancer, 30 with other cancers, and 50 normal controls were tested. The positive rates of PA_3antigen were 77.27% for lung cancer, 20.0% for other cancers, and 6.0% for normal individuals respectively, when cell-migration slowing rate≥35% was considered as the cutoff level....

    The authors report a novel immundelectrophoresis assay with hybridoma cells which secrete monoclonal antibody against lung cancer and its application in the detection of PA_3 antigen in lung cancer patients. Sera from 22 patients with lung cancer, 30 with other cancers, and 50 normal controls were tested. The positive rates of PA_3antigen were 77.27% for lung cancer, 20.0% for other cancers, and 6.0% for normal individuals respectively, when cell-migration slowing rate≥35% was considered as the cutoff level. The slowing rates of 4 positive sera from lung cancer patients could be inhibited by prior incubation with supernatant PA_3 hybridoma cells, suggesting that PA_3 antigen have restrictive expression in lung cancer. These data indicate that the detection of PA_3 antigen by hybridoma cellular immunoelectrophoresis may play a role in the serological diagnosis of lung cancer.

    本文报告一种新的杂交瘤细胞免疫电泳法及其在检测肺癌患者血清PA_3抗原中的应用。本法共检肺癌22例,其他癌30例,正常对照50例。以细胞电泳减慢率≥35%为分界标准,PA_3阳性率分别为肺癌77.27%,其他癌20.0%,正常人6.0%。4例阳性肺癌血清经PA_3杂交瘤细胞培养上清预反应后,其减慢率均受抑制,提示PA_3抗原在肺癌中的表达具有限定性。本文结果表明用杂交瘤细胞免疫电泳法进行PA_3抗原的检测对肺癌的血清学诊断可能具有一定价值。
