ABSTRACT
Purpose:To study the expression level of bcl 2 gene in breast cancer tissues, paracancer tissues, metastatic lymph nodes and normal tissues. To study the relation of the gene expression and tumor formulation, development and clinical significance. Methods:Semi fixed quantity RT PCR was performed in 16 patients to detect the level of bcl 2 gene expression in cancer tissues, paracancer tissues, metastatic lymph nodes and normal tissues. Results:The relative values of mRNA in cancer tissues was 0.264?0.137 and 0.272?0.076 in metastatic lymph nodes and 0.131?0.083 in paracancer tissues were higher than those in normal tissue (0.033?0.031), so the difference was significant( P
ABSTRACT
In this paper, the specific male sequeuce in paraffin section of various tissues with autolys is ofdifferent degrees was detected by polymerase chain reaction(PCR).The results shewed that PCR could be used for identifying sex in the tissues with low degrees ofautolysis; its positive rate was lower in high degrees with disappearance of nuclaic member and cell ou-tline,and often gave false negative results when the autolysis degree was high.
ABSTRACT
Objective To study the relationship between Lidocaine blood drug level and the cause of death from Lidocaine anaphylactic shock. Method Comparing and analyzing the blood drug levels by HPLC between two groups of people whose various indexes are normal before the surgery. Group 1 included 8 cases who accepted Lidocaine as anesthetic and died from Lidocaine anaphylactic shock. Group 2 included 11 cases who also took Lidocaine as anesthetic and passed the surgery smoothly. Results Lidocaine blood level of Group 1 (1.61?0. 45mg/L) is lower than that of Group 2 (2. 44 ?0. 47mg/L). Conclusion Lidocaine blood drug level has nothing to do with the cause of Lidocaine anaphylactic shock.
