OBJECTIVE:To detect and analyze the safety signals of pemetrexed in post-marketing,and provide references for rational drug use in the clinic. METHODS:A form of data mining techniques was used to detect the safety signals of pemetrexed in American adverse events reporting system and the analysis of signal effect factors i.e.,gender,age,dosage and indication was per-formed by SPSS 19.0. RESULTS:173 signals related to pemetrexed were excavated in 5 397 235 reports,and the number of report-ed adverse event in blood-lymphatic system was the most(491)and the number of signals in gastrointestinal system was the most (17). There was no statistical significance in the distribution of blood-lymphatic system and gastrointestinal system in gender(P=0.075) and age (P=0.726) compared to other system adverse event,but there was statistical significance in dosage (P=0.007) and indication(P=0.001). CONCLUSIONS:Adverse events induced by pemetrexed in blood-lymphatic system and gastrointestinal system should be monitored at the same time,especially combined with non-steroidal anti-inflammatory drugs.

Chinese materia medica (CMM) has double complexity in bioactive ingredient and its mechanism. It is difficult to explain by the modern biomedicine theory So it seriously restricts the modernization of CMM The modern CMM should have the high quality standard to meet the needs of international standard It can be guaranteed by spreading the GAP for Chinese medicinal materials and GMP for standard production The mechanism depends on using the DNA microarray to set up “the gene expression difference chart”, to study on the combination of CMM and gene expression difference chart Meanwhile, we can establish a totally new method of screening modern CMM based on the gene expression difference chart, it can really make the modernization and internationalization of CMM

ObjectiveBy the study of histological feature of the regenerated nerve at different time after operation,to explore the mechanism of the peripheral nerve regenerationwhen the distal nerve stump is repaired by a smaller proximal end with artery sleeve briding.MethodsFour Wistar rats were served as the donors of arteris for bridging.Sixteen Wistar rats were randomized into 2 groups (n =8 per group).In control group,the right sciatic nerves were cut off and received epineurial suture.In experimental group,the right sciatic nerves received artery sleeve bridging in different size.HE staining was taken to observe the histological changes of the regenerated nerve at 7,14,21 and 28 days after operation.ResultsThe new regenerated axons need about 21 days to pass the bridging gap.Twenty-eight days after operation,the number of the regenerated axons in distal segment was greater than that of the proximal in the experimental group.The regenerated axons were matured and more regular.Conclusion The functional reserve of repaired nerve is exists when the proximal end is smaller than the distal in size by means of amplification effect.And the method of artery sleeve bridging provides a better situation for functional reserve.

Objective To investigate the effect of the inhibitor SB203580 of p38 mitogen-activated protein kinase (MAPK) signal transduction pathway on biopterin (BH 4)/nitric oxide (NO) expression and elucidate the potential mechanism of MAPK in biopterin-mediated NO induction after endotoxic shock. Methods A total of 56 male Wistar rats were randomly divided into normal control group (n=8), endotoxic shock group (n=32) and SB203580 treatment group (n=16). After animals were sacrificed, tissue samples from the liver, the lungs as well as the kidneys were harvested to determine the expressions of guanosine triphosphate cyclohydrolase I (GTP-CHI) and inducible nitric oxide synthase (iNOS) mRNA and observe the changes of BH 4 and NO levels in blood and tissues. Results With endotoxin challenge, GTP-CHI mRNA expression and BH 4 levels were significantly elevated in various tissues and maintained at high levels up to 24 hours. Similarly, the iNOS mRNA expression and NO levels in the tissues significantly increased too, especially in the liver and the lungs. Treatment with SB203580 significantly down-regulated GTP-CHI mRNA expression in the liver, the lungs and the kidneys at 12, 24 and 2-12 hours, respectively (P
