Stereotactic Body Radiotherapy for Centrally Located Non-small Cell Lung Cancer / 中国肺癌杂志

A few study has proven that about 90% of local control rates might be benefit from stereotactic body radiotherapy (SBRT) for patients with medically inoperable stage I non-small cell lung cancer (NSCLC), it is reported SBRT associated overall survival and tumor specific survival is comparable with those treated with surgery. SBRT has been accepted as the first line treatment for inoperable patients with peripheral located stage I NSCLC. However, the role of SBRT in centrally located lesions is controversial for potential toxic effects from the adjacent anatomical structure. This paper will review the definition, indication, dose regimens, dose-volume constraints for organs at risk, radiation technology, treatment side effect of centrally located NSCLC treated with SBRT and stereotactic body proton therapy.

Influence and significance of atorvastatin on serum C-reactive protein level in acute cerebral infarction pa- tients / 中国实用内科杂志

Objective It is to study the influence of atorvatatin on serum C-reactive protein(CRP)level in acute cer- ebral infarction patients and to analyze its clinical significance.Methods 62 patients with acute cerebral infarction di- agnosed by CT or MRI were chosen and divided into two groups randomly.Both the groups were treated with normal method and the treatment group was given atorvastatin 20mg per day.Serum CRP levels in the two groups were measured by immunnturbidimetry within24h after final diagnosis and at two weeks the level decreased obviously in treatment.Re- slllts Serum CRP levels all increased in the patients.After treatment for two weeks the level decreased obviously in treatment group.The difference was significant compared with control group.Conclusion Atorvastatin can markedly reduce the serum CRP level in acute cerebral infarction patients and has important significance for the pathogenetic condi- tion change and prognosis of cerebral infarction.
