To study the effect of different storage conditions and storage time on herb quality of Lonicera macranthoides, different packaging materials including vacuum plastic bags, plastic bags, woven bags, sealed with endometrial bags, paper bags, sack bags were selected for the study under different storage conditions including room temperature, 5 degrees C refrigerator, low temperature of - 20 degrees C refrigerator and desiccator. Twenty-four batches of samples were used for the study, and active ingredients were determined. The experimental results showed that the ingredients in each storage group changed with the storage time, storage conditions (storage environment, packaging). Under the same storage time, the storage environment (temperature, humidity) had effect on the stability of herb quality. Low temperature had less effect on herb quality. The effect of packaging on herb quality was as following: plastic vacuum packaging > woven with endometrial sealed packaging > plastic bag > woven bag > sack bags > paper bags. Under the same storage conditions, with the increase of storage time, caffeic acid content increased slowly, and other five ingredients content decreased gradually. Storage time affected significantly on the intrinsic quality (chemical composition) and appearance of herb. It is suggested that low temperature (5 degrees C), dark and sealed storage are suitable for storage of L. macranthoides herb, the storage time should be not more than 24 months.

Objective To investigate the survival rates of main malignant tumors in Nanhui district. Methods Total 5 783 cases, registered as new cases with malignant neoplasm from 2002 to 2004 in Nanhui, were followed up. Data was studied by survival analysis with SPSS 13.0 of life table and Kaplan -Meier. Results The average annual crude incidence of malignant tumors was 267.57 / 100 000, the World standardized incidence rate of 209.98 / 100 000. Cancer Incidence in the top five ranks followed by lung, liver, stomach, colon and esophageal cancer, the incidence was 43.06 / 100 000, 28.65 / 100 000, 26.82 / 100 000, 18.63 / 100 000 and 9.57 / 100 000, respectively. The difference of the survival rates between the top five cancers was remarkable. Survival rates of cancers among males from the lowest to the highest were liver, lung, esophagus, stomach and intestines. Survival rates of cancers among females from the lowest to the highest were of liver, lung, esophagus, stomach, intestines, cervical and breast. The male or female main cancer's relative survival rate droped along with the age rising. Conclusion The survival status was better in the patients with intestine cancers and female patients with breast cancer, but worse in patients with liver, ung and esophageal cancer.

ObjectiveTo enrich and quantitatively analyze peripheral circulative carcinoma cells by magnetic activated cell sorting (MACS) in colorectal cancer patients.MethodsBlood samples, preoperatively collected from 21 patients with colorectal cancer and 9 healthy volunteers, were labeled by anti-cytokeratin (CK) with magnetic microbeads, and passed through magnetic columns; CK +carcinoma cells were separated from the samples, and quantified by flow cytometry.ResultsCK +CD45 -cells could not be detected from the samples without MACS; in the sample undergoing MACS, the concentrations of CK +CD45 -cells were significantly higher in patient group than in control group(P
