Objective: To assess therapeutic effect of alprostadil on improving myocardial microcirculatory disturbance and hemorheological disorder in patients with coronary heart disease (CHD).Methods: A total of 164 CHD patients treated in our hospital were selected.According to random number table method, they were randomly and equally divided into routine treatment group and alprostadil group (received alprostadil injection based on routine treatment group), both groups were treated for two weeks.Serum levels of nitric oxide (NO), vascular endothelial growth factor (VEGF), thromboxan β2 (TXβ2) and hemorheological indexes were measured and compared between two groups after treatment;TIMI grade and TIMI myocardial perfusion grading (TMPG) of CAG were compared between two groups after treatment.Results: Compared with routine treatment group after treatment, there were significant rise in serum levels of NO[(64.9±10.3) mmol/L vs.(98.8±13.2) mmol/L]and VEGF[(1.62±0.53) mg/L vs.(3.31±0.68) mg/L], and significant reduction in serum TXβ2 level[(180.4±22.8) pg/ml vs.(78.9±9.6) pg/ml], P<0.05 or<0.01;significant reductions in whole blood high shear viscosity[(5.84±0.72) mPa·s vs.(4.25±0.31) mPa·s], whole blood low shear viscosity[(8.42±0.93) mPa s vs.(5.31±0.68) mPa s], plasma viscosity[(2.73±0.34) mPa s vs.(1.61±0.29) mPa s], fibrinogen level[(4.09±0.55) g/L vs.(3.13±0.55) g/L], erythrocyte aggregation index[(3.85±0.47) vs.(2.24±0.31)]and maximum platelet aggregation rate[(67.4±5.3)% vs.(48.0±3.6)%]in alprostadil group, P<0.05 all.Among those patients undergoing second CAG, compared with routine treatment group, there were significant reductions in percentages of TIMI and TMPG grade II and grade III, and significant rise in percentages of TIMI and TMPG grade 0 and grade I in alprostadil group, P<0.05 or <0.01.Conclusion: Alprostadil can significantly improve myocardial microcirculatory disturbance and hemorheological disorder in patients with coronary heart disease, which is worth extending.

BACKGROUND: Embryonic stem cell (ESC) is a kind of highly undifferentiated totipotent cell. It can proliferate and maintain its totipotency in the system cultured in vitro. It is one of most promising stem cells in thetreatment of central nerve injury.OBJECTIVE: To observe the survival and migration of induced transplanted ESC in mice with spinal injury and hypoxic-ischemic encephalopathy.DESIGN: A completely randomized grouping design, controlled animal experiment.SETTING: Laboratory of Developmental Biology Research Center of Shanghai Second Medical University.MATERIALS: Sixty C57/BL6J mice, of clean grade and either gender, aged 6 to 8 weeks (n =30) and 7 days (n =30)were provided by the Shanghai Experimental Animal Center, Chinese Academy of Sciences [Permission No, SCXK (hu)2003-0003]. This animal experiment was approved by Animal Ethics Committee. Mouse ESC strain S8, labeled LacZ marker gene (Provided by Shanghai Developmental Biology Research Center). X-gal dyeing reagent (Sigma Company).METHODS: This experiment was carried out in the laboratory of Shanghai Developmental Biology Research Center (Shanghai Key Laboratory) from October 2002 to December 2003. ① Experimental grouping of spinal injury: Sixteen C57/BL6J successful mice models, aged 6-8 weeks, were randomized into 2 groups: experimental group (n =8), in which, following right spinal semi-sectioning, derivated cell suspension for inducing the in vitro differentiation of ESC was injected at 1 cm away from injury through vertebral canal, and control group (n =8), in which, following right spinal semi-sectioning, phosphate buffer solution (PBS) was injected at the peripheral region of injury. ② Hypoxic-ischemic encephalopathy experimental grouping: Sixteen successful C57/BL6J mice models, aged 7 days, were randomized into 2 groups: experimental group (n =8), following ligation of right common carotid artery, mice were placed in the closed container containing 0.08 volume fraction of oxygen and 0.92 volume fraction of Nitrogen gas, and taken out 1.5 hours later; 3 μL ESCs were injected into the right cerebral ventricle at about 1 week, and control group (n =8), in which, the same amount of PBS was injected into the right cerebral ventricle. ③ At 12 weeks after transplantation, the survival and migration of induced ESCs labeled by Lac-Z in the spinal cord and brain were observed by zymologic method.MATN OUTCOME MEASURES: Survival and migration of ESCs in the central nervous system.RESULTS: ①After being induced in vitro and transplanted to spinal injured region, ESCs differentiated into neural precursor cells. Neural precursor cells could survive in the injured region and migrate to 5 mm away from injured region.Immunohistochemistry proved that the neural precursor cells of transplanted ESCs could differentiate into neurons.Morphologically, it was proved that neural precursor cells-derived from ESCs could well integrate peripheral tissue. ② The induced ESCs were injected into the lateral cerebral ventricle of mice. Derived ESCs widely distributed in the injured hippocampal region, cerebral cortex ventricle choroid plexus, vascular endothelium and other regions, and integrated peripheral tissue, which were similar to adjacent cells in morphology, suggesting that induced ESCs also could survive for long time and far migrate.CONCLUSION:The induced ESC can survive and migrate in the host injured brain and spinal cord, and the migration of ESCs is more obvious in the brain than in the spinal cord.

Teaching reform for medical statistics in postgraduate students was undertaken in order to comply with the longitudinal thought of medical research and to cultivate student's abilities of solving actual problems. The contents of theory courses and practicum courses were re-enacted and some advanced statistical methods commonly used in medical research were added. Meanwhile,the contents of practicum courses were reformed following the guideline of ‘application of statistics in the research’ and the teaching method of task-driven teaching combined with problem-based learning was used in the process. Furthermore, evaluation on the teaching effect was made. The reformed teaching model greatly excited student's learning enthusiasm and developed their abilities of applying statistics in scientific research.
