The study of chemiluminescence in gastric and colonic carcinoma cell lines treated by anti-tumor drugs.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
aimTo study the influence of chemotherapy on proliferation activation of tumor cell by observing the change of chemiluminescence (CL) and cell cycle in various tumor cell lines after mitomycin C treated.
methodsBGC823 and LoVo cell lines were all cultured in RPMI-1640, and then were adjusted to a concentration of 1X10(5) cells/ml in fresh media and incubated for 24 h. Mitomycin C (100 ng.ml(-1)) was added to each bottle. All indeses were examined after 24 h. No Mitomycin C was added in control group. Each group contained 8 samples. Flow cytometric analysis and luminol-dependent CL were used to investigate the effect of mitomycin C on two gastrointestinal carcinoma cell lines.
resultsBGC823 and LoVo cell lines incubated with MMC for 24 h. We discovered that the emergence of peak of CL stimulated by PHA was postponed significantly (BGC823: 12.63+/-3.21 vs 4.50+/-1.04, LoVo: 13.25+/-2.96 vs 5.12+/-1.36, P<0.01) and the peak intension of CL was reduced significantly (BGC823: 120.25+/-16.61 vs 248.38+/-29.17, LoVo: 98.13+/-10.49 vs 267.50+/-18.56, P<0.01). The PI of cell lines was decreased significantly (BGC823: 51.87+/-4.82 vs 25.44+/-2.26, LoVo: 47.11+/-1.04 vs 24.23+/-0.37, P<0.01) and the apoptotic fractions changed by contraries (BGC823: 26.25+/-5.29 vs 9.83+/-2.51, LoVo: 33.50+/-3.68 vs 9.63+/-1.44, P<0.01).
conclusionCL can be used to measure activation of tumor cells. We discovered that the ground CL intensions of two cell lines were not high but increased rapidly after stimulation of PHA. The CL peak ranged from 4-5 minutes, and then decreased gradually. The results were not reported before. CL of tumor cell has close correlativity with the dynamics of cell cycle and can reflect the feature of oxidation metabolism and proliferation activation of tumor cell. So it can be used to observe the influence of chemotherapy drug on metabolism and proliferation activation of tumor cell and screen out chemotherapy drugs to which tumor cells are sensitive.
