Chinese Journal of Medical Imaging Technology 2009;25(12):2306-2308
The growth of brain metastasis needs appropriate microenvironment, and the change of normal brain microenvironment is the basis for exploring metastasis with MRI. Through the local magnetic field changes and the application of contrast agents for improving the discrepancy of the cerebral tissue, MR can accurately detect brain metastasis in position, number, size, and shape. MR with contrast-enhanced technique is the first choice for screening brain metastasis. The application of all kinds of new MR techniques, sequences and intracellular contrast agents can not only further improve the specificity of detection, but also improve the sensitivity of MRI, which is favorable to formulating reasonable treatment and prolonging the lifetime of the patients. The microenvironment of brain metastasis and advances in the new MR techniques were reviewed in this article.

Objective To develop a method for the determination of four saponins of panax notoginseng in Compound Dan-shen Prescription (CDP) by HPLC. Methods The conditions for the experiment were: determination of notoginsenoside R1, ginsenoside Rg1 and ginsenoside Re with acetonitrile - 0. 05 % phosphoric acid (19 : 81) as mobile phase and the detection wave at 203nm, determination of ginsenoside Rb1 with acetonitrile - water (33 : 67) as mobile phase and the detection wave at 203nm. Results A good linearity for notoginsenoside R1 was in the range of 0. 24 ~ 3. 6?g ( r = 0. 9997), 1. 2 ~ 18?g (r = 0. 9994) for ginsenoside Rg1, 0. 08 ~ 1. 2?g(r = 0. 9997) for ginsenoside Re and 0. 25-3. 72?g (r = 0. 9998) for ginsenoside Rb1. The stability of the four saponins is well kept at 4℃ for four months. Conclusion This method is simple, rapid, accurate and with good reproducibility and can be used for the quality control of CDP.

Objective: To study the quality of life (QOL) and its influencing factors of elderly hospitalized terminal patients. Methods: The scale of Life Quality, Social Support Inventory, Life Satisfaction Index A(LSIA), Hospital Anxiety and Depression Scale(HAD), degree of pain (Verbal Report Scale, VRS) and Activities of Daily Living(ADL) were administered in 152 elderly hospitalized terminal patients. Results: 1)The total score of each scale was QOL 36.9?7.4, ADL56.27?34.5,Social Support 40.0?6.3, HAD(A)8.9?4.1,HAD(D)11.2?4.9,LSIA 11.6?3.9?2)Pearson's correlation showed that QOL scores were negatively correlated with degree of pain (r=-0.54,P

Objective: To study the anti-tumor effect of recombinant human MUC1-MBP. Methods: The C57BL/6 mice were in oculated with MUC1-MBP by subcutaneous. MUC1 specific CTL activity of spleen were determined by MTT; The effects on prevention and treatment of tumor were observed by establishing lewis lung cancer-carrying mice. Results: The cytotoxicity of CTL from immunized mice to the MCF7 and Lewis lung cancer cells respectively was (47.7?4.3) % and (67.5 ?6.5) %; 5?10 5 lewis lung cancer cells following immunization were injected iv into C57BL/6 mice, after three weeks, the number of lung and tail tumor colonies was 51 and 5 for PBS and MUC1-MBP groups respectively and the suvival time was significantly delayed in immunized mice. The average volume of tumors in mice with MUC1-MBP was 386 mm 3 wherea control group was 4 000 mm 3 at tumor treating experiment. Conclusions: Recombinant human MUC1-MBP have significantly effects on prevention, treatment and inhibiting metastases of tumor.
