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 establish the quality standard of Shujinzhuanggu pill. METHODS: Thin-layer chromatography(TLC) was employed for the qualitative determination of Psoralea corylifolia,Panax notoginseng,Angelica sinensis, Cyperus rotundus and Dipsacus asperoides. High performance liquid chromatography(HPLC) was applied for the determination of Psoralen in psoralea corylifolia in Shujin zhuanggu pill. RESULTS: The characteristic identification by TLC was distinctive and highly specific. The linear range of Psoralen was 0.04~0.28 ?g (r=0.999 2). The average recovery was 98.84 and RSD was 2.17%. CONCLUSION:The established standard can be used for the quality control of Shujin zhuanggu pill.

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.

Objective To determine the effects of dose reduction on multi-slice spiral CT(MSCT) of neonatal head and assess the lowest possible radiation for acceptable clinical images.Methods Fifty-seven newborns suspected intracranial hemorrhage were entered into the study and underwent MSCT scans.Original images at three anatomic levels (posterior fossa, basal ganglia, centrum semiovale) were collected and synthetic noise was added so as to simulate dose reductions of 25%, 40%, 50% and 70%, respectively by using the noise addition tool.A total of 855 image data sets were obtained for the 57 patients.Original and simulated dose-reduction scan images were analyzed.Image noise and image quality were assessed by two independent experienced pediatric radiologists using diagnostic acceptability score, subjective image noise score on a 5-peint scale and objective noise index.Image noise was measured by respectively placing region of interest (ROI) at cerebellum, thalamus and corona radiata of 3 different slices.And the noise index and mean value was calculated.The degree of inter-observer concordance was determined by Kappa statistical analysis.The Spearman statistical correlations between the noise index and diagnostic acceptability score were performed.Results On the images of original dose and simulated dose reductions of 25%, 40%, 50% and 70%, the diagnostic acceptability was 4.47±0.51, 3.96±0.33, 3.21±0.45, 2.92±0.32, and 1.85±0.57, respectively,the subjective image scores were 1.62±0.48, 1.99±0.48, 2.76±0.81, 3.19±0.67, and 4.27±0.54, respectively, the noise index were 1.90±0.19, 2.17±0.20.2.44± 0.25, 2.68±0.28, and 3.37±0.39, respectively.The two radiologists had good intembserver agreement for diagnostic acceptability (K=0.860, P=0.017) and for image noise scoff ng (K=0.630, P=0.022).There was significant statistical correlation between image noise index and diagnostic acceptability (r= 0.826,P=0.001).At 40% dose reduction to the standard protocol, the noise index was 2.44 and the image quality score was 3.21 which were considered clinically acceptable.Conclusion The study revealed that acceptable imagos could be obtained with mean noise index of 2.44 and 40% dose reduction.

Objective To study the application CT scans in Nuss procedure for pectus excavatum. Metlhods 648 children with pectus excavatum underwent Nuss procedure from July 2002 to September 2008 The preoperative CT scan was carried out for evaluation of the deformity degree and morphology classification of chest wall malformation, the deformity in relation with adjacent tissue and associated different disorder. Results Nuss procedure was successfully performed in all 648 patients. The preoperative CT scan showed medium deformity of the pectus excavatum in 73 cases ( 11.27% ) and severe deformity in 575 cases (88.73%). Morphologic classification of the pectus excavatum were symmetric type in 407cases (62.81% ) , eccentric type in 83( 12.81% ) ,and unbalanced type in 158( 24.38% ). 116 cases with pectus excavatum were associated with other different disorders, among them 55 cases ( 17.9% )were diagnosed by CT scan. 28 cases received stimultanously operation for their abnormalities. Conclusion CT scan is a useful tool for evaluation the deformity degree and morphology classification, direct the operation, reduce the complications and find other different disorders. It should be a routine examination before Nuss procedure.
