1.On the Legal Capacity of Fetal Rights——An Analysis from the Ethical and Legal Perspective
Chinese Medical Ethics 1995;0(02):-
There are many arguments on the legal capacity of fetal rights for a long time,but no definite conclusion has ever been reached.Based on ethics and approached in jurisprudence,this article tries to jump out of the traditional mode to analyze the reasons for the independent personality of fetus and justify the view that legal capacity of fetal rights does not necessarily require additional restrictions.The legal capacity of fetal rights origins from social ethical values.Morality distinguishes right from wrong,law pursuits for justice,and moral value is the basis of the law and human nature.The definition of legal "person" should first respect for the objectivity of human development process and the nature of human.It's necessary to recognize the independent personality of fetus,protect the vulnerable groups,and the people in the most vulnerable stage of human development on the basis of social moral value.The directive function of law on morality should be enhanced in our nomocracy-favored society,so as to achieve the reunification of fetal rights in the context of harmonious society construction and realize the human virtue of excellence and harmony.

Objective: To investigate the correlation of thrombospondin-1(TSP-1) expression and angiogenesis and clinical pathologic factors in breast cancer. Methods:Reverse transcription-polymerase chain reaction (RT-PCR) was used to detect the expression of TSP-1 mRNA in the primary breast cancer tissues and the tissues set apart 5 cm from the tumor. Im-munohistochemistry was used to detect the expressions of vascular endothelial growth factor (VEGF), c-erbB2, estrogen receptor (ER), progesterone receptor (PR) and microvessel density (MVD). All data were statistically analyzed. Results: The positive rate of TSP-1 was significantly higher in breast cancer than that in tissues set apart 5 cm from tumor (P < 0.05). The expression of TSP-1 was positively correlated with tumor size only (P < 0.05). MVD was lower in TSP-1 positive group than that of negative group (P< 0.05). Conclusion: The MVD was decreased with up-regulation of TSP-1 expression. Thrombospondin-1 may repress the angiogenesis in breast cancer.

Objective To analyze the correlations between liver lipid level determined by liver 3.0 T 1H-MRS in vivo and influencing factors using multiple linear stepwise regression. Methods The prospective study of liver 1H-MRS was performed with 3.0 T system and eight-channel torso phased-array coils using PRESS sequence. Forty-four volunteers were enrolled in this study. Liver spectra were collected with a TR of 1500 ms ,TE of 30 ms, volume of interest of 2 cm ×2 cm ×2 cm, NSA of 64 times. The acquired raw proton MRS data were processed by using a software program SAGE. For each MRS measurement, using water as the internal reference, the amplitude of the lipid signal was normalized to the sum of the signal from lipid and water to obtain percentage lipid within the liver. The statistical description of height, weight, age and BMI, Line width and water suppression were recorded, and Pearson analysis was applied to test their relationships. Multiple linear stepwise regression was used to set the statistical model for the prediction of Liver lipid content. Results Age (39.1 ± 12. 6) years, body weight (64.4 ± 10. 4) kg,BMI (23.3 ±3.1) kg/m2, linewidth (18.9 ±4.4) and the water suppression (90.7 ±6.5)% had significant correlation with liver lipid content (0.00 to 0.96%, median 0. 02% ), r were 0.11,0. 44,0. 40,0. 52, - 0. 73 respectively(P < 0. 05 ). But only age, BMI, line width, and the water suppression entered into the multiple linear regression equation. Liver lipid content prediction equation was as follows: Y =1.395-(0.021 × water suppression) + (0.022 × BMI) + (0.014 × line width) - ( 0. 064 × age),and the coefficient of determination was 0.613, corrected coefficient of determination was 0.59. Conclusion The regression model fitted well, since the variables of age, BMI, width, and water suppression can explain about 60% of liver lipid content changes.

BACKGROUND: Bone cement coated by different materials has various characteristics and causes varying therapeutic effects. OBJECTIVE: By comparing characteristics of CPC, CPC/D, and CPC/M/D3 to investigate the preparation of doxorubicin microspheres-coated bone cement. METHODS: Doxorubicin microspheres were prepared with multiple emulsion solvent volatilixation method. Doxorubicin microspheres were mixed with CPC as the ratio of 3:7 to prepare doxorubicin microspheres-coated bone cement. The samples were randomly divided into three groups: CPC group, containing bone cement alone; CPC/D group, containing doxorubicin;CPC/M/D group, containing doxorubicin microspheres. Scanning electron microscope at varying magnification was used to observe structural characteristics and measure the diameter of microspheres. X-ray diffraction was used to estimate the extent of CPC and CPC/M/D samples. The initial and final setting time of cement samples in the three different groups was measured at 25 ℃ and 37℃ respectively. The injectability and interval porosity of different samples were tested. The compressive strength of the specimens was measured using a universal material testing machine to record the maximal compressive strength and breaking strength. RESULTS AND CONCLUSION: PLGA microspheres (100-150 μm) were globular and the surface was slick and sly. Micrestructure of bone cement was not obviously changed following mixing with drugs, thus the location and characteristics of drugs in bone cement were not determined. Micrespheres-coated bone cement (100-150 μm) was distributed among CPC powder. All the X-ray diffraction pattern of three different samples was in coincidence with standard X-ray diffraction pattern of hydroxyapatite, i.e., the major peak was located near 32°. Additional drugs and microspheres did not cause new phases. Obvious collapsing was not observed in the three samples following immediately adding in saline, but the collapsing appeared in both CPC/D and CPC/M/D samples after 24 hours. The setting-up time of CPC/M/D was the longest, but that of CPC was the shortest. On the other hand, the setting-up time was the longest at 37℃. The final setting-up time of CPC/M/D group was 45 minutes. The doxorubicin microspheres-coated bone cement showed the best property of injectability among the three kinds of cement. The interval porosity was the highest in the CPC/M/D group but the lowest in the CPC group. Interval porosity of doxorubicin microspheres-coated bone cement was up to 61.67%. The yield stress was the strongest in the CPC group but the weakest in the CPC/M/D group. Additionally, the yield stress of calcium phosphate cement dramatically decreased while doxrorubicin microspheres were coated. However, there was no significant difference between them. The preparation of doxorubicin microspheres-coated bone cement was reliable and the product had good structures and properties.
