Résumé
Aortic dissection is a life-threatening condition for which diagnosis mainly relies on imaging examinations, while reliable biomarkers to detect or monitor are still under investigation. Recent advances in technologies provide an unprecedented opportunity to yield the identification of clinically valuable biomarkers, including proteins, ribonucleic acids (RNAs), and deoxyribonucleic acids (DNAs), for early detection of pathological changes in susceptible patients, rapid diagnosis at the bedside after onset, and a superior therapeutic regimen primarily within the concept of personalized and tailored endovascular therapy for aortic dissection.

Objective To preliminary investigate the clinical efficacy of whole brain simultaneous integrated boost intensity-modulated radiotherapy ( SIB-IMRT ) in patients diagnosed with brain metastases ( BM) . Methods Fifty-two cases of BM admitted to our hospital from January 2016 to December 2017 were equally recruited and randomly divided into the observation and control groups. Patients in the observation group were treated with SIB-IMRT, and those in the control group received conventional whole brain radiotherapy (WBRT).The clinical efficacy and prognosis were statistically compared between two groups. Results The ORR in the observation group was 77％, significantly higher than 27％ in the control group (P=0. 00).The median survival in the observation group was 384 d,significantly longer compared with 211 d in the control group (P=0. 00).All patients in both groups successfully completed corresponding treatment. Acute adverse reactions were mainly 1-2 grade reactions. Conclusions SIB-IMRT is an efficacious and safe treatment of BM,which yields tolerable adverse events and deserves application in clinical practice.

Objective To evaluate the role of 11C-methionine positron emission tomographv(MET PET-CT)in differentiating tumor recurrence from radiation necrosis in brain slioma patients.Methods From June 2008 to September 2009,30 brain glioma patients with suspected tumor recurvence or radiation necrosis after radiotherapy were evaluated by MET PET-CT.The median time between initial radiotherapy and PET examination was 13.5 months.Tumor recurrence were confirmed by histological analysis while necrosis was based on histological analysis or the subsequent clinical follow-up.Results Eighteen out of 19 patients were histologically confirmed tumor recurrence among those tumor recurrence shown by MET PET-CT after surgery or stereotactic biopsy.11 patients were considered to have radiation necrosis because of stable neurological sympotoms and without massive enlargement of the lesion during the after follow-up.The sensitivity,specificity and accuracy of MET PET-CT for detecting tumor recurrence were 100%,91.7%and 96.7%respectively.Conclusion MET PET-CT is a powerful tool in differentiating brain tumor recurrence from radiation necrosis after radiotherapy.
Résumé
Objective To develop the system of computer information processing for radiotherapy. Methods Visual Foxpro 5.0 was used to program the system through the model of client-server machine. SQL-server was used as the database-server.Results The main function of this system was management of the case data for radiotherapy and make plans for radiotherapy. Conclusion This system operates steadily with the data safe and reliable. It can be used extensively in clinical practice.
Résumé
AIM: To establish the determination of astragaloside Ⅳ in Renzhujianwei Granules. METHODS: HPLC ELSD method was developed for the determination of astragaloside Ⅳ in Renzhujianwei Granules on Lichrospher 5 C 18 (200mm?4.6mm) with Methanol H 2O(100∶20) as a mobile phase (0.8mL?min -1 ). RESULTS: The average recovery was 96.97% and the linear equation was Y=6.3073+1.4277X. The correlation coefficient was 0.9998. CONCLUSION: The method is simple, rapid, and accurate.
