Based on amino acid score of food, this article presents an "Amino Acid Score Difference (AASD) " for protein quality evaluation, the minus value of AASD representing the limiting amino acid and its number re- presenting the degree. The minus value in one food can be compensated by the positive value in another when we directly select the rational couple for amino acid complementation in diet. In addition, a calculation formula is introduced for amino acid complementation in two kinds of food or in mixed diet including many foods. It gives an effective means in evaluating the nutritional value of protein in foods and planning an ideal diet by selecting foods on the basis of amino acid complementation

Aim To investigate the effect of hesperidin on human lung cancer cell A549 and the possible mechanism.Methods The cell apoptosis and necrosis of A549 treated with hesperidin were measured by the Hoechst 33342/PI fluorescent dye based on microfluidic chip technology.Cell cycle and apoptosis rate were evaluated by flow cytometry(FCM).The expressions of the related genes were detected through the real-time fluorescent quantitative PCR technology(RT-PCR) including VEGF, PI3K and PTEN.The protein expressions of Bcl-2, Cyclin B1, PI3K, Akt and PTEN were detected by Western blot after hesperidin intervention.Results The proliferation of A549 cells was significantly inhibited by hesperidin in a dose-dependent manner.FCM results showed that hesperidin could not only influence the G0/G1 phase and S phase, but also promote the apoptosis of lung cancer cells.Meanwhile, the apoptosis and necrosis rate was increased from(6.7±0.6)% to(27.9±1.1)% compared with that of control group(P<0.05).From the level of molecular, the gene expressions of VEGF and PI3K were decreased, while the PTEN was increased after hesperidin stimulation.Western blot results showed that the expression of protein Bcl-2, Cyclin B1 and Akt were decreased, which all showed close relationship with cell apoptosis, cell cycle and PI3K-Akt signaling pathway.The expression of PI3K was increased, but the change of PTEN was not statistically significant compared with that of control group.Conclusion Hesperidin induces lung cancer cell apoptosis through PI3K-Akt signaling pathway, which blocks cancer cell division and destroys the balance of related protein expression.

Objective To observe the efficacy of antiviral therapy of pegylated interferon (Peg-IFN) α-2a combined with ribavirin for patients with hepatitis C cirrhosis and hypersplenism underwent splenectomy or partial splenic embolization. Methods Thirty-eight patients with hepatitis C cirrhosis (genotype Ⅰ HCV infection) hypersplenism failed to the anti-viral therapy were performed splenectomy or partial splenic embolization to improving hypersplenism. After 3 months,Peg-IFNα-2a 90μg or 135 μg was given subcutaneously once weekly, plus ribavirin 600-1 000 mg/d orally for 1 year of the treatment. During the treatment, patients were followed at four-week intervals, and then followed-up every month until the 24th week after stopping. Liver function, blood routine, renal function, HCV RNA, and adverse reaction of medication were observed during treatment and the follow-up period. Results Splenic function of patients with hepatitis C cirrhosis and hypersplenism was improved after hypersplenism splenectomy or partial splenic embolization. The sustained virologic response (SVR) rate was 63.88%after giving Peg-IFNα-2a combined with ribavirin anti-viral treatment. Conclusion After splenectomy or partial splenic embolization, patients with hepatitis C cirrhosis and hypersplenism showed the better SVR at the treatment of Peg-IFNα-2a combined with ribavirin. The treatment could delay the progress of the hepatitis C cirrhosis and reduce the incidence of liver failure and liver cancer.

Objective To explore the correlation between serum Lipoxin A4 and clinical grading of chronic hepatitis B patients. Method The serum Lipoxin A4 was detected by Enzyme-Linked Immunosorbent Assay in 94 chronic hepatitis B patients. Results It was found that the level of serum Lipoxin A4 of severe hepatitis patients were significantly lower than mild hepatitis patients and moderate hepatitis patients ( =0.04 and =0.03) . The serum Lipoxin A4 levels were correlated negatively with the ALT and AST levels,respectively =-0.41, =0.019 and R=-0.37,P=0.034. Conclusion These findings support the fact that the serum Lipoxin A4 may contribute to clinical grading of chronic hepatitis B patients.

Objective To investigate the diagnostic value of random forest(RF)model based on CT images and clinical data for preoperative T staging of colorectal cancer. Methods Four hundred and fifty patients with colorectal cancer who were pathologically confirmed by surgery and underwent preoperative CT examinationinthe first hospital of Jilin university from January 2016 to July 2016 were included retrospectively(Stage≤T2,T3,and T4 each has 150 cases).According to the ratio of 2:1,the patients were divided into training set(300 cases)and test set(150 cases,stage ≤T2,T3,and T4 each has 50 cases)by computer random software. Each of 450 patients had one lesion. All the patients underwent preoperative abdominal and pelvic contrast-enhanced CT scan.The clinical,imaging and pathological data[gender,age, carcinoembryonic antigen (CEA) level, carbohydrate antigen 19-9 (CA19-9) expression, intestinal wall deformation, maximum diameter of tumorand thickness of intestinal wall, location, enhancement homogeneity and enhancement rate]of these patients were collected.The correlation between the collected factors and pathological T staging was analyzed by Spearman correlation analysis.The preoperative staging model of colorectal cancer was established by RF algorithm in the training set.Two kinds of methods(model and traditional method)were used to diagnose T stage of the patients in the test set.The accuracy of the two methods was calculated by postoperative pathological staging as the gold standard.The consistency test was used to evaluate the consistency of the RF model results with the pathological results. Results T-staging was positively correlated with CEA, CA19-9, intestinal wall deformation, tumor size and thickness of intestinal wall(r=0.449,0.291,0.624,0.573,0.386;P<0.05).Age,location,enhancement homogeneity and enhancement rate were slightly negatively correlated with T-staging(r=-0.115,-0.245,-0.120 and-0.339;P<0.05).The predictive results of the model in≤T2,T3,and T4 stage cancers were moderately and highly consistent with the standard of pathology,and the Kappa value were 0.769,0.615 and 0.800,respectively.The total accuracy rate of the model andthe traditional method are 80.7%(121/150)and 54.0%(81/150). Conclusion Application of random forest model based on multi-slice spiral CT images and clinical data can improve the diagnostic efficacy of preoperative T stage of colorectal cancer.
