RESUMO
Lignans are compounds found in a variety of plant materials including flaxseed, pumpkin seed, sesame seed, soybean, broccoli, and some berries. The major lignan in flaxseed is called secoisolariciresinol diglucoside (SDG). Once ingested, SDG is converted in the colon into active mammalian lignans, enterodiol, and entero-lactone, which have shown promise in reducing growth of cancerous tumors, especially hormone-sensitive ones such as those of the breast, endometrium, and prostate. Known for their hydrogen-donating antioxidant activity as well as their ability to complex divalent transition metal cations, lignans are propitious to human health. The extraction methods vary from simple to complex depending on extraction, separation, fractionation, identification, and detection of the analytes. Flax lignan is also a source of useful biologically active components found in plant foods, such as phytochemicals, and it is considered a functional food. The safety issues in flaxseed are also briefly discussed.

RESUMO
Objective To investigate the effect of Avastin (bevacizumab) combined with preoperative FOLFOX neoadjuvant chemotherapy on the prognosis of patients with locally advanced rectal cancer (LARC).MethodsA total of 80 cases of patients with LARC treated with total mesorectal excision (TME) in our hospital from January 2013 to January 2016 were randomly divided into the control group and the observation group, 40 cases in each group.The control group were treated with preoperative FOLFOX chemotherapy while the observation group were treated with bevacizumab injection, based on the treatment in the control group.21 days was a cycle of chemotherapy, and both groups were treated for at least 4 cycles.After 6 cycles of chemotherapy, operation was carried out, following TEM principle.The short-term and long-term prognosis, rate of R0 resection, the incidence of postoperative complications and side effects of chemotherapy were compared between the two groups.ResultsThere was no significant difference between the two groups in the good response rate of chemotherapy, the rate of R0 resection, the incidence of postoperative complications, the 1-year and 3-year survival rates and 1-year disease-free survival rate.The incidence rates of gastrointestinal reactions and bone marrow suppression in the observation group were 52.5% and 52.5%, respectively while in the control group were 25.0% and 20.0%, respectively (P<0.05), but there was no significant difference in the incidence rates of grade Ⅲ~Ⅳ gastrointestinal reaction and bone marrow suppression between the observation group and the control group (5.0% and 15.0% vs 2.5% and 5.0%).The 3-year disease-free survival rate of the observation group was higher than that of the control group (82.5% vs 60.0%) (P<0.05).ConclusionThe application of bevacizumab combined with preoperative FOLFOX chemotherapy in the treatment of LARC can improve the 3-year disease-free survival rate, without increasing postoperative adverse reactions and serious side effects of chemotherapy.
RESUMO
A new and convenient method was developed to separate and identify exo- and endoinulinase from Aspergillus ficuum by native polyacrylamide gel electrophoresis. Eight protein bands were obtained. Three bands were identified as exoinulinase, and two bands were endoinulinase, by using TLC and HPLC. The five bands were all detected as glycoproteins with the sensitive periodic acid-silver stain.

Objective BALB/C mice were inoculated subcutaneously with hepatoma 22 (H22) cells, and the treatment effect of thalidomide and intratumor injection of ethanol extract of Scutellaria Barbata (SB) on tumor growth were evaluated. Methods In vitro, mouse H22 liver cells were cultivated, and H22 cells in the logarithmic growth phase were tested. SB was extracted in the ethanol recirculation. A total of 28 BALB/C male mice inoculated subcutaneously with H22 cells were randomly divided into 4 groups, 7 mice per group. Group A:intragastric administration with thalidomide. Group B:SB intratumor injection. Group C:combination of thalidomide and SB with the same administration as Group A and Group B. Group D (control group):1% Ethanol 0.2~0.5 mL intratumor injection. Tumor volumes of four groups were observed and the tumors were weighed. The microvessel densities (MVD) of all transplantation tumors were measured by immunohistochemical staining with anti-CD31 monoclonal antibody. Results There were statistically significant differences between Group C and Group A (P 0.05). The studies showed statistically differences between Group C and Group A (P
RESUMO
OBJECTIVE:To observe the influence of Valsartan on the serum ET,CGRP levels,urinary protein and Q - Td of patients with CRF complicating hypertension.METHODS: CRF research group including 24 patients with CRF complicating hypertension receiving Valsartan 80mg/ d for 4 weeks; CRF control groups including 20 CRF patients with normal blood pressure; health group including 9 health people.The serum ET and CGRP levels, urinary protein, and Q - Td were measured.RESULTS: (l)The serum ET level of CRF patients was higher than that of health people;The serum ET level of CRF research group(before treatment) was higher than that of CRF control group and decreased after treatment of Valsartan.(2) The serum CGRP level of CRF patients was higher than that of health people .The serum of CGRP level of CRF research group (before treatment) was higher than that of CRF control group and continued to increase after treatment of Valsartan. (3) The content of urinary protein of CRF patients was significantly higher than that of health people.The content of urinary protien of CRF research group before treatment was higher than that of CRF control group and decreased after treatment of Valsartan. (4) The Q - Td of CRF research group was longer than that of health group and CRF control group.But the Q - Td of CRF research group did not change after treatment of Valsartan.CONCLUSION: Valsartan could effectively control blood pressure and decrease content of urinary protein, and delay the deterioration of renal function, but could not reverse the cardiovascular remoulding.
