Objective To explore the role of phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT) pathway in recombinant human erythropoietin( rhEPO) protecting new type BPD. Methods Injected LPS or PBS to 40 spra-gue-dawley (SD) rats, gestational sacs on 15th day of gestation, the newborn rats were divided into four groups:control group, hyperoxia group, rhEPO group, rhEPO+LY294002 group. To detect the expression of lung tissue BCL-2 and Caspase - 9 protein and mRNA by Western blot and RT-PCR. Results In the hyperoxia group and rhEPO+LY294002 group, BCL-2 expression was decreased,while Caspase-9 expression was increased apparently;in the rhEPO group, BCL-2 expression was increased, while Caspase-9 expression was decreased. The differences between each group were statistically significant on 1st,7th and 14th day of hyperoxia exposure (P<0. 05). Con-clusion Intrauterine inflammatory exposure combined with hyperoxia after birth can cause lung cell apoptosis in-creases. While rhEPO has certain control effects on BPD, possibly by reducing the pulmonary apoptosis. The mechanism may be associated with PI3K/AKT signaling pathway.

Objective To explore CT angiography(CTA) method for the influence of the cerebral angiography ,looking for dif-ferent situations using which kind of scan mode can achieve the best results .Methods 350 CTA patients were selected and tested by 4 kinds of scanning methods which were subtraction scan (236) ,experience value scan (13) ,smart tracking scan (68) ,smart tracking and subtraction combined(33) .To compare and analyze that four kinds of scanning methods ,to explore which kind of method under what circumstances can get the best examination results .Results Smart tracking and subtraction combined with scan method and subtraction scan method for excellent rate of image quality were 93 .93% and 93 .64% respectively ,there were no sig-nificant statistical differences between them .Experience value method and smart tracking method for excellent rate of image quality were only 76 .92% and 66 .18% ,there was significant difference in statistics .Conclusion Subtraction scan can be used as a conventional scan method .In low dose test bolus of time-density curve detection failure cases ,smart tracking and subtraction combined with scan method was used to get the image quality with subtraction scan method ,it is an effective complement of subtraction scan method ,is worth generalization .

In patients with initially diagnosed unresectable cancers,resection of cancer sometimes becomes possible by systemic chemotherapy,and this model of chemotherapy is defined as conversion chemo-therapy. Conversion chemotherapy can improve objective response rate and resection rate,and it has shown an important value in metastatic colorectal cancer,advanced gastric cancer and unresectable hepatocellular carci-noma.

Cancer precision therapeutics is defined as a therapy strategy based on molecular profiles and classifiers generated from high-throughput molecular assays.Precision therapeutics in oncology is becoming reality thanks to the next-generation sequencing and cancer targeted agents.Selecting optimal targets,identif-ying appropriate combinations of therapies and real-time monitoring of tumor evolution may be critical for practi-cing precision therapeutics.

As semi-autonomous organelles,mitochondria are easily damaged by various factors.Mitochondrial dysfunction such as abnormal oxidative phosphorylation,metabolism alterations,apoptosis prevention,damaged mitophagy,immune escape and deregulated signaling pathway have been hypothesized to be involved in tumorigenesis.Modulated mitochondria may prevent the occurrence of tumors.

As a way of gene modification,alternative splicing is an important factor of eukaryotic gene expression and regulation.It makes various transcripts from one protein-coding gene,and greatly extends the genetic information.Alternative splicing of pre-messenger RNA plays an important role in tumor cells.By alter-native splicing,some important genes can generate splicing variants different from those in normal cells.The existence of tumor-specific splicing variants leads to the occurrence and progression of tumor.Therefore,explo-ration on the alternative splicing of tumor-associated genes may be of great significance in tumor diagnosis and treatment.

As small non-coding RNAs,microRNAs (miRNAs)have been recognized as important reg-ulatory factors in the post-transcription regulation network.Studies have shown that miR-133a and miR-133b, as members of miR-133 family,can regulate the expression of target genes such as epidermal growth factor receptor and oncogene.They regulate the mitogen-activated protein kinases and protein kinase B signaling path-ways,which affect tumor cell proliferation,invasion and migration.MiR-133 plays a key role in the process of tumor development and progression,suggesting that it could be served as a new target for cancer treatment.

Maintenance therapy is an important strategy for cancer treatment,which mainly include continuation maintenance therapy and switch maintenance therapy,with a classical model of metronomic chemo-therapy.Maintenance therapy can be an effective treatment option for patients with non-small cell lung cancer, breast cancer,colorectal cancer and ovarian cancer.
