Protective effect of Chinese medicinal Lerbs against gastric stress injury was studied.The compound antioxidant prescription used was composed of ten herbs, each of which had proven antiperoxidation action. Bound-soaked rats were used as victims of stress injury. In the two groups of rats under protection of the "prescription and injection of salvia" the indexes of gastric mucosa injury were 8.50?2.31 and 19.00?4.25, LPO in serum were 10.74? 0.94 and 11.80? 1. 06nmol/ml respectively. Both were significantly decreased as compared with the control group (39.00? 6.50, LPO 19.06? 1. 10nmol/ml ). These results signified that the antioxidant medicinal herbs, especially in compounded form, may prevent gastric stress injury

Objective To highlight the diagnose and treatment of stationary paraganglioma in retroperitoneum.Methods Ten cases of stationary medullary chromaffinoma of retroperitoneum proven pathologically from 1997 to 2007 were reviewed and sutdied.Hypertension were not observed in all patients,who were admitted to hospital through routine phisical examination.Endocrine secretion examinations,B-US,CT,MRI,131IMIBG,and octreotide were used to dianose the diease.Among all 10 patients,4 cases took ?-receptor blocker for 2～4 weeks preoperatively.3 were operated laparoscopically,7 were operated with lumber incision.Results Hypertension and urinary catecholamine was usually normal or elevated lightly in stationary medullary chromaffinoma of retroperitoneum.131and octreotide have high sensitivity and accuracy in diagosing medullary chromaffinoma.4 were near renal hilum,6 was in para-aorta.They were from 3 cm to 15 cm in size.The results of pathology were paraganglioma in 7 and malignant paraganglioma in 3.Tumor markers were positive,such as cgA,syn,NSE and s-100.There was 1 case metastasis 1 years later.Conclusion Once the correct diagnosis is made,surgical treatment should be carry out on the basis of correct drug preparation.Intimate follow-up is necessary and important.

0.05).There was a significant positive correlation between serum osteocalcin and ESR in female patients with RA aged less than 50 years (P

Objective To evaluate the safety and efficacy of CT-guided transgluteal approach for drainage of deep pelvic abscesses. Methods From April 2000 to August 2007, 12 patients with deep pelvic abscesses underwent CT-guided transgluteal drainage. The clinical data, number of drainage cathete rsplaced, amount of drain, duration of placement, complications and follow-up were retrospectively analysed.Results One drainage catheter was successfully placed for each patient. The amount of abscess drained was30 to 180 ml (mean 52 ml) and the duration of placement was 6 to 34 days (mean 11 days). No major complications occurred. Conclusion The transgluteal approach to the drainage of deep pelvic abscess under CT guidance was safe and effective.

Muscle recently has been identified as a good source of adult stem cells that can differentiate into cells of different lineages.Researchers have identified two types of stem cells in skeletal muscle.Further research is necessary to delineate the relationship between different populations of musclederived stem cells(MDSCs)and between MDSCs and other adult stem cells.The methods used to isolate these cells appear to influence the stem cell characteristics.As these efforts continue,the potential for MDSCsbased therapy for other musculoskeletal injuries,as well as for cardiac and smooth muscle injuries,is currently being explored.The behavior,biocharacteristic,isolation,differentiation and the probability of application to regenerate lost or diseased tissue of MDSCs were summarized.

This paper has reported the effect of preservation myceh'al fungus by the methods of slant and rubber plug. The mycelial fungus preserved include 29 genera, 69 species, 128 strains. The preservation time is from 2 years to 17 years. By slant inoculation, their survival conditions are still good keep their original charaters. The result shows that it is simple and effective preserving some mycelial fungus by the methods of slant and rubber plug.

Objective To investigate the relationship between serum lipid and bone mineral density in post-menopausal women.Methods Bone mineral density(BDM)was measured at a variety of skeletal sites,including lumbar spine 2(L2),3(L3),4(L4)2~4(L2~L4),femoral neck(Neck),trochanter(Troch),Ward's triangle,using the Norland XR-36 dual-energy X-ray absorptiometer in northern Chinese healthy population-based sample of 60 post-menopausal women from 2002 to 2006 in our hospital.Serum lipid profiles of total cholesterol(TC),low-density lipoprotein(LDL),Triglyceride(TG)and high-density lipoprotein(HDL)were examined.Results HDL-C correlated inversely with BMD in both lumbar spine(P

Objective To explore the changes of positron emission tomography(PET)in newborn infants with HIE through 18F-fluorodeoxyglucose(18F-FDG)and it's significance.Methods Eleven healthy newborn infants and 8 newborn infants with HIE were selected.Among the healthy newborns,7 cases were male and 4 cases were female,and the mean birth-weight was(3 350?620)g,the gestational age was(37.9?1.3)weeks.Among the HIE neonates,5 cases were male and 3 cases were female,and the mean birth weight was(3 180?390)g,the gestational age was(37.1?2.4)weeks.There were no significant differences of sex and gestational age between the 2 groups.The examination time was form 3 to 21 d,and the mean age was(8.7?3.9)d.PET of the children in 2 groups were observed after 0.1 mCi/kg 18F-FDG injected 30 min.Results The brain 18F-FDG PET image in newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with that of the adults,and that was not as clear as that of adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher.The structure of brain 18F-FDG image was significantly changed in newborn infants with HIE,especially increased in the areas of peripheral ventricle and hypophloeodal cerebral white matter,and there was a remarkably bilateral asymmetry.Conclusions Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

Objective To study the clinical values of positron emission tomography(PET)in pre-term and term newborn infants through observing neonatal brain by 18F-fluorodeoxyglucose(18F-FDG)PET.Methods The brain by 18F-FDG PET in 11 term and 7 pre-term newborn infants after administration of 0.1 mCi /kg 18F-FDG were observed.There were 11 males and 7 females,who were normal by brain computed tomography or magnetic resonance imaging.Results The brain 18F-FDG PET image in pre-term and term newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher,and the structure of brain 18F-FDG image was more clear in term infants than that in pre-term infants.Conclusion Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

BACKGROUND:There are many studies concerning rat bone marrow mesenchymal stem cells for immune tolerance following transplantation and tissue repair.However,there are no reports on umbilical cord mesenchymal stem cells(UCMSCs).OBJECTIVE:To establish a method of separating mesenchymal stem cells(MSCs)from rat umbilical cord,and to study its biological characteristics.METHODS:MSCs were separated from rat umbilical cord with enzyme method and tissue mass method,and then incubated in DMEM-LG medium.Cell morphology was observed under an inverted microscope.Growth curves of cells were drawn using cell counting.Cell cycle and surface antigen were detected with flow cytometry.Adipogenic differentiation and osteogenic differentiation were tested by immunohistochemistry.RESULTS AND CONCLUSION:Both of the two methods could obtain plenty of MSCs from rat umbilical cord.Primary culture showed that the efficiency of enzyme method was higher than tissue mass method.Passage time of the former was about 10 days and the latter was 14 days.The passage time of latter except primary culture was the same.Immunophenotype analysis showed that MSCs from rat umbilical cord expressed adhesion molecule and stromal cell markers,CD90 and CD106,but did not express hematopoietic cell markers,CD34 and CD45.In vitro induction test verified that rat UCMSCs have the potentials of adipogenic and osteogenic differentiation.
