Gelation of crocodile myofibrillar protein - κ-carrageenan mixtures in two low-NaCl solution.

Crocodile meat is a novel reptile meat source, but its processing method is rare. This study investigated the effect of κ-carrageenan addition and partial substitution of NaCl on the gel properties of crocodile myofibrillar protein (CMP). Result showed that CMP formed gel when temperature above 60 ℃. The water-holding capacity, gel strength, denaturation degree, sulfhydryl content covalent bond and hydrophobic bond of gel in KCl solution were significantly higher than those in CaCl2 solution (P < 0.05). K+ induced CMP to form a tight network structure with uniform small pores though covalent and hydrophobic bonds, but the gel properties were reduced by κ-carrageenan. In CaCl2 solution, κ-carrageenan improved the gel structure by filling the protein network through hydrogen bonding. Therefore, it can be concluded that KCl is better than CaCl2 in the manufacturing of low-sodium crocodile foods. Moreover, κ-carrageenan was only beneficial to gel quality in CaCl2 solution.

Prognosis and related factors of acute lymphoblastic leukemia / 中国实验血液学杂志

In order to analyze the prognosis and related factors of acute lymphoblastic leukemia (ALL), 53 newly diagnosed ALL patients were enrolled in this study. The therapeutic efficacy and prognosis of 53 cases of ALL were analyzed, the remission, relapse, overall survival and event-free survival were studied, and relation between different factors and prognosis of ALL were investigated by comparison of cases in same stage. The results showed that the complete remission was achieved in 36 out of 53 patients, the total remission rate was 67.9%, the total relapse rate was 37.7%, the median relapse duration was 6 months after remission. Median overall survival (OS) and median event-free survival (EFS) time were 4 and 1 months after remission respectively, OS and EFS rate of 18 month was 35.1% and 14.2%. The patients with different gender had significantly different EFS. Age was an independent risk factor of CR rate. White blood cell count and hemoglobin level of newly diagnosed patients were significantly correlated with OS and EFS. Absolute neutrophil count (ANC) at the end of the induction chemotherapy was an independent related factor of OS, the higher ANC, the lower risk of death. The patients with or without chemotherapy related infection had different relapse rate. The patients with bleeding after chemotherapy had lower OS when compared with those without bleeding. Serum glucose level was a significant negative prognostic factor. It is concluded that there is higher relapse rate, poor prognosis in adult ALL in comparison with children. In order to decrease the relapse rate and prolong the EFS, individual therapeutical regimens and prophylaxis of complicating diseases should be applied to ALL patients.

Analysis on prognosis and correlative factors of acute nonlymphocytic leukemia / 中国实验血液学杂志

To analyze the prognosis and risk factors of acute nonlymphocytic leukemia (ANLL), 94 patients with acute nonlymphocytic leukemia were enrolled in this study, while survival rate and risk factors of prognosis were analyzed. The results indicated that the complete remission (CR) ratio was 51.1%. Overall survival and event-free survival rates of month 6, 12, 18, 24 were 68.6%, 55.8%, 53.8%, 46.4%, 21.3% and 57.9%, 38.6%, 33.3%, 31.6%, 0% respectively. The factors such as age<40 years, WBC<10.0x10(9)/L before chemotherapy, WBC in the period of bone marrow suppression<1.0x10(9)/L, chemotherapy within 1 month after occurrence of leukemia, blood transfusion before chemotherapy of APL had favourable influence on remission and survival rates of ANLL patients. CR1, the time to get CR, length of CR and relapse significantly correlated with prognosis (p<0.05). It is concluded that the individualized therapy concerning the risk factors should be applied to ANLL patients for improving the remission, survival rate and prognosis.
