Objective To explore the influencing factors of therapeutic effect and prognosis in patients with angioimmunoblastic T cell lymphoma (AITL). Methods The clinical data of 48 patients with AITL were collected in order to evaluate its therapeutic effect and the influencing factors of prognosis. Results In the 48 patients with AITL, complete remission (CR) was in 15 cases, partial remission (PR) was in 16 cases, and the total effective rate was 64.58%(31/48). The recent total effective rate in patients of international prognostic index (IPI) score ≤2 scores was significantly higher than that in patients of IPI score >2 scores: 84.00% (21/25) vs. 43.48% (10/23), and there was statistical difference (P<0.05). The 1-year, 2-year and 3-year overall survival rates were 75.00%(36/48), 52.08%(25/48) and 35.42%(17/48), and the median survival time was 24.5 months. The patients of Ann Arbor stage Ⅰ-Ⅱ, IPI score ≤ 2 scores, Ki-67<50% and using CHOP combined with asparaginase (ASP) regimen had a higher 3-year overall survival rate compared with the patients of Ann Arbor stage Ann Arbor stage Ⅲ -Ⅳ, IPI score >2 scores, Ki-67 ≥ 50% and using CHOP regimen: 8/13 vs. 25.71%(9/35), 52.00% (13/25) vs. 17.39% (4/23), 55.00% (11/20) vs. 21.43% (6/28) and 48.28% (14/29) vs. 3/19, and there were statistical differences (P<0.05). Conclusions AITL is a kind of disease with poor prognosis. IPI score is the important influencing factor of recent therapeutic effect. The Ann Arbor stage, IPI score, Ki-67 levels and using contained ASP chemotherapy are the important factors of prognosis in patients with AITL.

The total volatile components were extracted from safflower by ultrasonic-assisted solvent extraction （USE） and their chemical constituents were analyzed by gas chromatographymass spectrometry （GC-MS） to provide scientific basis for the quality control of safflower. Five different solvents （diethyl ether, ethanol, ethyl acetate, dichloromethane and acetone） were used and compared in terms of number of volatile components extracted and the peak areas of these components in TIC. The results showed that USE could be used as an efficient and rapid method for extracting the volatile components from safflower. It also could be found that the number of components in the TIC of ethyl acetate extract was more than that in the TIC of other solvent ones. Meanwhile, the volatile components of safflower from Xinjiang Autonomous Region and Henan Province of China were different in chemical components and relative contents. It could be concluded that both the extraction solvents and geographical origin of safflower are responsible for these differences. The experimental results also indicated that USE/GC-MS is a simple, rapid and effective method to analyze the volatile oil components of safflower.

An inductively coupled plasma mass spectrometry （ICP-MS） or inductively coupled plasma atomic emission spectrometry （ICP-AES） was developed to determine 19 elements in safflower, a traditional Chinese medicinal herb from Xinjiang Autonomous Region and Henan Province of China. Totally 19 elements in safflower included heavy metals, i.e. As, Cd, Cu, Hg and Pb, and wholesome elements, i.e. Al, Ca, Co, Cr, Fe, Mg, Mn, Mo, Ni, P, Se, Sr, V and Zn. The results showed that the concentrations of heavy metals in safflower samples were both low, all of which met the national hygiene standards except for Pb in Xinjiang sample. Meanwhile, the distribution tendency of elements in the two samples was similar, which indicated that the plant might absorb given elements in a proportional way. The method can be used for the quality control of elements in safflower, and it provides a way for the determination of the contents of safflower from Xinjiang and Henan.
