To understand the process of passenger transportation on the urban and rural roads accurately, objectively and reasonably, this article in six aspects of the station yard layout, line network, operation management, service level, fiscal policy and technical equipment, constructing a multi-level evaluation index system of complete.

This study was designed to evaluate the antioxidant activity of samples extracted from Jinhua ham. The activities of SOD and contents of MDA and NO were measured after mice were kept on feeding the four peaks separated by using chromatographic column. Peak-3 obviously enhanced the activity of SOD and MDA. Peak-1 and peak-2 had little influence on the activity of SOD and MDA. Peak-4 decreased their activities. All peaks obviously decreased content of NO. Results showed that these four peaks had excellent antioxidant activity. Finally, influences of sample extracted from ham on SOD activity, MDA content and GSH-PX activity in vitro of mouse liver and heart were also studied. Certain dose of samples would lead the decrease of SOD activity, MDA content and GSH-PX activity. This results showed that the sample have certain oxidant capacity.

This study was designed to evaluate the antioxidant activity of samples extracted from Jinhua ham by using such chemical assays as DPPH, scavenging hydroxyl free radical and ABTS. The results demonstrate that antioxidant capacity of the extracted sample is lower than oxidation capacity of Vc. The IC50 spot of samples ranges between 0.6 % and 2.5 % (mass fraction of solute).

To predict the passenger travel sharing rate in the inter-city comprehensive passenger traffic channels, the passenger transport properties of the inter-city comprehensive passenger transport channels were combined, variables with different characteristics were introduced into utility function, the application of Logit model was improved, the comprehensive passenger transport channels of Guangzhou-Huizhou, Shenzhen-Huizhou, Dongguan-Huizhou were taken as examples to conduct the prediction applications of the passenger travel sharing in the railway passenger transportation, highway passenger transportation and non-commercial transportation. The results showed that the improved model could effectively carry out the passenger travel share prediction in inter-city comprehensive passenger transport channels.

The beef flavor was selected to carry out toxicological analysis regarding food intake, body weight, organs weight and blood biochemical indexes in mice. The results show that beef flavor could suppress food intake but promote mice weight compared with the control group. Flavor intake has significant effect on the ratio of liver and lung weight to the whole body weight, but it has no difference in the ratio of heart, spleen and kidney weight. Some biochemical indexes about fat metabolism in blood such as the total protein, total bile acid and alkaline phosphatase are respectively 4 g/L, 0.7μmol/L and 23 IU/L more than the control group. These factors and cholesterol, triglyceride, low density lipoprotein, high-density lipoprotein cholesterol in the mice blood all have extremely significant differences (P

In China, many kinds of natural products extracted from plant and animal were used to treat cancer. Flavonoids extracted from tartary buckwheat and skin peptide purified from rufous-spotted torrent frog had respectively been proved to have anti-tumor activity. In present study, both tartary buckwheat flavonoids and amphibian frog peptides were applied for cell proliferation inhibitory activity against human gastric cancer MGC 80-3 cells using MTT assay. According to the data, the buckwheat flavonoids exhibited much stronger anti-tumor activity than amphibian peptides, and the complex mixture of this two kinds of bioactive compounds still possess anti-tumor activity.
