Medical imaging involves not only the multidisciplinary knowledge,but also the concurrent updating of the knowledge system related to the imaging technology development.In this case,it's an important issue how to guarantee the teaching quality of the medical imaging postgraduate education effectively and cultivate the professsionals with higher comprehensive quality in the limited teaching time available.Thus the implementation as well as the teaching effects of the reading report in the promotion of medical imaging postgraduates' research ability and comprehensive quality is needed to be discussed from the accumulation and update of knowledge system.

OBJECTIVETo observe the effect of Weichang'an (WCA, a Chinese preparation) in preventing post-operative metastasis of progressive stage of gastric cancer.

METHODSA prospective randomized, controlled study was conducted by dividing the 148 patients of progressive staged gastric cancer after radical operation into the WCA group, the chemotherapy (CT) group and the WCA + CT group, to observe the survival rate, metastasis rate, quality of life (QOF) and tumor-bearing survival time after relapse (TST) in patients.

RESULTSThe 1-, 2- and 3-year survival rate after operation in the WCA + CT group was 89.51%, 69.77% and 55.76% respectively, which was significantly higher than that in the CT group (83.86%, 59.33% and 49.43%) respectively (P < 0.05), but showed insignificant difference as compared with that in the WCA group (93.23%, 79.34% and 71.78%). Only 1-year metastasis in the WCA group was 15.25%, and in the WCA + CT group was 15.52%, the two were significantly lower than that in the CT group (35.48%, P < 0.05). But the comparison of 2-year metastasis rate among the 3 groups (28.81%, 41.38% and 45.16%) and 3-year metastasis rate among them (33.90%, 46.55% and 51.61%) were insignificantly different. The QOF and TST were markedly better in the WCA group than those in the CT group.

CONCLUSIONWCA has preventive effect on relapse and metastasis in post-operational gastric cancer patients.

Objective To observe the apoptosis of human large cell lung cancer NCI-H661 cells induced by crotoxin,and to explore its mechanism. Methods The growth suppression of crotoxin on the NCI-H661 cells was detected by CCK-8 colorimetry,and the formation of NCI-H661 cells was observed by the plat colony experiment. This experiment included 4 groups:negative control group,crotoxin group(60 μg/ ml cro-toxin acted for 24 h),crotoxin + SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then 60 μg/ ml crotoxin acted for 24 h),SB203580 group(pretreated cells using 5 μmol/ L SB203580 for 1 h,then cultivated cells using complete culture solution). They were detected that the cell cycle and apoptosis rate of NCI-H661 cells treated with crotoxin by the flow cytometry. Additionally,they were tested that the change of the cell cycle and apoptosis rate after the NCI-H661 cells were treated with crotoxin and the activity of p38MAPK was inhibited by SB203580. Results When the concentration of crotoxin was greater than or equal to 30 μg/ ml,the inhibitory effect of crotoxin on the activity of NCI-H661 cells and colony formation,and inhibi-tion rate rose with increasing function of time and drug concentration. Flow cytometry showed that the apoptosis rate of crotoxin group and crotoxin + SB203580 group were(16. 70 ± 1. 38)% and(2. 15 ± 0. 54)% ,com-pared to the control group(1. 47 ± 0. 29)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 18. 763,P = 0. 000;t = - 1. 935,P = 0. 125). The G1 period cells of crotoxin group and crotoxin + SB203580 group were(57. 25 ± 1. 09)% and(48. 04 ± 1. 03)% ,compared to the control group(47. 46 ± 0. 69)% ,and the former difference was statistically significant and the latter was not statistically significant(t = - 13. 124,P = 0. 000;t = - 0. 809,P = 0. 464). Conclusion Crotoxin can promote the apoptosis of human large cell lung cancer NCI-H661 cells,and this effect may be related to the excitation of p38MAPK signal pathway.

Objective To observe the clinical efficacy of acupuncture plus medicine and function training in treating post-stroke shoulder-hand syndrome. Method Sixty patients with post-stroke shoulder-hand syndrome were randomized into a treatment group of 30 cases and a control group of 30 cases. The treatment group was intervened by acupuncture plus medicine and functional training, while the control group was only by functional training. Before and after intervention, the hand swelling degree, Visual Analogue Scale (VAS), shoulder joint motion scale, Fugl-Meyer Assessment (FMA) scale were used to measure the swelling and pain of hand, motion of shoulder, and motor function of upper limb. Result After intervention, the swelling and pain of hand, motion range of shoulder and motor function of upper limb were significantly improved in both groups (P<0.01), and the improvements in the treatment group were more significant than that in the control group (P<0.05). Conclusion Acupuncture plus medicine and function training can enhance the efficacy in treating post-stroke shoulder-hand syndrome, superior to pure function training.

Leaves of Chrysanthemum morifolium were potential medicinal resource. The present study aims to estimate the main bioactive components: total flavonoids (TF), galuteolin (GA), quercitrin (QU), chlorogenic acid (CA) and 3 ,5-O-caffeoylquinic acid ( CQ), which were considered to be the main effective components, in leaves of C. morfolium cultivars in China. The TF content was estimated hy UV-VIS spectrophotometry, while GA, QU, CA, and CQ were quantitatively determined by HPLC. The highest TF content (7. 13% w/w) was found in cultivar Wan Cong (Shexian county). Cultivar Da Bo ( Bozhou county) had the highest GA content (33. 45 mg - g-1); Cultivar Hong Xin (Sheyang county) contained the highest QU content (29.25 mg · g(-1)); Cultivar Chang Ban (Sheyang county) had the highest CA content (13.14 mg ·(-1)). The maximum CQ content (7.35 mg · g(-1)) was observed in culti- r Da Yang ( Tongxiang county). Different cultivars of C. morfolium had significant difference in components, but the leaf and capitulum of C. morifolium. were found to possess similar chemical compositions. The high content of bioactive components in several cultivars suggested the potential utilization of C. morifolium leaves.

This study was aimed to quantitatively detect the level of maf-b mRNA in leukemia patients and evaluate its clinical significance. Real-time fluorescence quantitative PCR was used to detect the relative expression level of maf-b mRNA. The expression change of maf-b mRNA in various types of leukemia was analyzed. Then, the relationship of maf-b mRNA expression with laboratory index and the response to chemotherapy was analyzed. The results showed that maf-b mRNA expression level in acute myeloid leukemia (AML) patients was lower than that in normal group (p<0.01) and positively correlated with white blood cell count (p<0.01) and the expression of CD34 (p<0.01). There was no correlation between maf-b mRNA expression level and chemotherapy response in AML patients except for acute promyelocytic leukemia (APL). Maf-b mRNA expression levels in acute lymphoid leukemia (ALL) and chronic myeloid leukemia (CML) patients were also lower than that in normal group (p<0.01). It is concluded that there is low expression of maf-b gene in AML patients. Abnormal expression of maf-b correlates with abnormal proliferation of AML cells, which may be a new prognostic factor for AML.

The combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata can increase efficacy and decrease toxicity. This study started from the phenomena of protein self-assembly in the mixed decoction of Glycyrrhizae Radix et Rhizoma with Aconiti Lateralis Radix Preparata. The attenuated mechanism was explored between the combination of Glycyrrhizae Radix et Rhizoma and Aconiti Lateralis Radix Preparata by using the protein of Glycyrrhizae Radix et Rhizoma and aconitine which was the major toxic component of Aconiti Lateralis Radix Preparata. Glycyrrhizae Radix et Rhizoma protein with aconitine could form stable particles which particle mean diameter was (206.2 ± 2.02) nm and (238.20 ± 1.23) nm at pH 5.0 in normal temperature. Through the mouse acute toxicity experiment found that injection of aconitine monomer all mice were killed, and injection of Glycyrrhizae Radix et Rhizoma protein-aconitine particles with the same content of aconitine all mice survived. Survey the stability of Glycyrrhizae Radix et Rhizoma protein-aconitine shows that the colloid particles is stable at room temperature, and it has the possibility to candidate drug carrier. Glycyrrhizae Radix et Rhizoma protein can reduce the toxicity of aconitine through self-assembly.
