To observe the progess of pharmacological and clinical researches on Xiangsha-Liujunzi decoction by literature reviews recently. Pharmacological study found that the Xiangsha-Liujunzi decoction can protect the gastric mucosa, regulate gastrointestinal endocrine function, promote apoptosis of hyperplasia epithelial cell lying the gastric mucosa, and promote antidepressant effect. Thus, Xiangsha-Liujunzi decoction could be used for gastrointestinal diseases and tumor postoperative gastrointestinal dysfunction caused by radiation and chemotherapy.

Objective To study the therapeutical effects of compound Danshen injection combined with edaravone in treatment of acute cerebral infarction.Methods 130 cases of ACI were randomly divided into two groups, control group(65 case) and observation group(65 cases), control group were administered with edaravone injection, while observation group were administered with compound Danshen injection and edaravone injection, NIHSS score and Barthel index score were used for effects evaluation, meanwhile, serous levels of copeptin, NT-proBNP and Hcy were measured by ELISA assay.Results Observation group had a better effect on ACI care, compared with control group (P<0.01), and serum levels of copeptin,NT-proBNP and Hcy significantly improved both in the two groups ( P <0.01 ) , while, observation group had a better effects ( P <0.01 ) . Conclusion Combination therapy of compound Danshen injection and edaravone has a fabulous effect on ACI care.

Objective:To study the influence of intensive magnet fields on radiation dose measurement, and to demonstrate the feasibility of measuring magnet field correction factor by a combination of medical linac with variable magnet fields in view of needing for accurate measurement of the doses from reference beam arising in MR image-guided radiotherapy.Methods:A photon radiation field and a variable field with 6 MV nominal high voltage were produced by using conventional medical electron linear accelerator equipped with a pair of electromagnets with magnetic field strength up to 1.5 T. Both PTW30013 and PTW31010 ionization chambers were used to test the responses of ionization chambers under different magnetic field strengths at four orientations in which the angles between ionization chamber axis and magnetic field direction were 0°, 180°, 90° and 270°, respectively. The magnetic factors, kB, M was calculated and compared with the reported values in literature. Results:The response of ionization chamber was proportional to the magnetic field strength before it reached to a peak around 1 T, and then fell down as the magnetic field continued to rise. When the magnetic field was 0.35 T, the magnetic factors of PTW31010 were 0.988 2±0.000 3 and 0.997 4±0.000 4 corresponding to 90° and 0° directions, the discrepancy between 0° scenario and literature was 0.05% ± 0.04%. When the magnetic field reached 1.5 T, the magnetic factor of PTW30013 was 0.958 9±0.000 5 at the situation of 90°, which was 0.60% ± 0.05% different from the literature value.Conclusions:Conventional 6 MV medical accelerator equipped with electromagnet can be used to measure the magnetic field factor of reference dosimetry for MRIgRT.
