Objective:To explore of clinical value of three-dimensional computed tomography angiography(3D-CTA) in the etiological diagnosis and management of intracranial aneurysm.Methods:One hundred and fifteen patients with spontaneous SAH admitted from September 2007 to August 2008 were examined with 3D-CTA,and were examined with digital subtracted angiography(DSA),and eighty nine patients were found suffering from intracranial aneurysm which underwent DSA.Repeated 3D-CTA was performed 1 week after clipping in eighty one patients or embolization in eignt cases.The findings of 3D-CTA were compared with the results of DSA.Results:A total of ninty seven aneurysms in eighty nine cases were detected by 3D-CTA,but DSA revealed ninty three anurysms.DSA confirmed the findings of CTA except for five cases of small anterior communicating aneurysms and three cases posterior communicating aneurysms which were demonstrated by 3D-CTA and verified by surgery but missed by DSA and four cases which were found by DSA and verified by surgery but missed by 3D-CTA.The sensitivity of 3D-CTA to diagnose the intracranial aneurysms is 95.6% and the specificity is 100% and the accuracy is 96%.The diagnose accordance rate among 3D-CTA and DSA and/or surgery is 88.1%.Conclusion:3D-CTA and 2D-DSA and/or surgery have high diagnose accordance rate,and we should combine the two diagnostic techniques to examine intracranial aneurysms accurately.

Objective To evaluate the efficacy and adverse events of oxcarbazepine(OXC) on the children with partial epilepsy.Met-hods Sixty-four children with partial epilepsy were divided into 2 groups.Forty-one newly diagnosed patients who had never accepted standard therapy entered monotherapy group,and 23 patients who had many anti-epileptic drug(AEDs) in turn with poor efficacy served as add-on therapy group.The initial dose was 4-8 mg/(kg?d).The dosage was increased by one time every 2 weeks,and should not exceed 10 mg/(kg?d) in each time.The maintenance dose was 28-40 mg/(kg?d).With open-label autocontrol method,the efficacy and adverse events of OXC were analyzed during the first 6 months of treatment both in 2 groups.Results The effective rates were 85.4%,69.6% and 79.7%,in monotherapy,add-on therapy and total groups.The seizure free rates were 53.7%,17.4% and 40.6%.It showed that the seizure frequencies between 2 groups at 6 months after therapy were significantly difference(P0.05).The common adverse events were dizziness,headache,fatigue and nausea.Six patients had dropped out because of rashes,however,they all recovered after drug withdrawal and nonspecific therapy.Conclusion The efficacy of OXC is sustained with good safety and tolerability profiles on the treatment of children patients with partial epilepsy.

[Summary] Transplantation of human cell, tissue or organ is an effective means to cure completely the disease. Animal experiments and clinical studies have demonstrated that the efficacies of transplantation are obvious in the treatment of hypothyroidism. In recent years, thyroid stem cell transplantation has drawn much attention, embryonic stem cells, bone marrow mesenchymal stem cells and adult stem cells had also made progress in clinical investigations. Especially the embryonic stem cell transplantation has been used successfully in animal experiments. It provided a new perspective for clinical thyroid transplantation, but it also faces many problems to solve.

Platelet -derived growth factor (PDGF)is an important factor of promoting cell growth which has a physiological role ranging from DNA synthesis,cell mitosis inducement,promotion on a variety of extracellular matrix accumulation as well as impact on the cell phenotype and growth.Studies showed that PDGF played an important role in growth and proliferation of vascular and nerve.It has a significant effect on accelerating tissue repair and promoting healing of chronic diabetic foot ulcers.

Objective Diabetic cardiomyopathy is a heart disease that excludes coronary heart disease,hypertensive heart disease and other heart diseases,and patients with diabetes mellitus prone to cardiac structural and functional changes.Echocardiography is often the first choice of examination methods,and nuclear magnetic resonance and nuclear magnetic resonance imaging is a new method to observe the changes of myocardial fibrosis and myocardial metabolism.In the treatment,need to a variety of methods to intervene,such as blood glucose control,using statin lipid -lowering drugs,angiotensin converting enzyme inhibitor,angiotensin receptor blocking agent,beta blockers,antioxidants,and traditional Chinese medicine etc.

Objective The aim of the study is to investigate whether the progressive incremental exercise can induce the change in bone maximum force.Methods One hundred and seventy healthy SD rats,aged 3 months,were used as samples after adaptive exercise for one week,and then they were divided to a basic control group(C_0),8 control groups and 8 exercise groups according to the training duration(2W,4W,6W,8W,9W,11W,13W and 15W).Based on Bedford and our pre-study.the longest training duration of the rats was 15 weeks.The maximum force(F) of femoral bone and the 2nd lumbar vertebrae(L_2)were tested by three-point bending test and compressive test separately.Results It was shown that there was no pronounced difference in F of femoral bone between con trol groups and exercise groups.But significant differences in F of L_2 were found between the control groups and exercise groups(P<0.001).Conclusions Changes in different degree were found in the F of femoral bone and L_2 during the process of growth.The differential effects of incremental exercise on F were caused by the difference in training intensities and in the bone types.

The authors discussed the retention and revision of the Regulations on the Handling of Medical Malpractice following the enforcement of the Tort Liability Law.These discussions also covered the amendment of the concept of medical malpractice,and the reforms to make on the medical malpractice appraisal system built upon the Regulations following the enforcement.In the meantime of applying the Law to judge cases of medical malpractice,the Regulations as an administrative regulations issued by the State Council,should be revised before playing its role in preventing medical malpractice,medical dispute handling,and penalising medical institutions and medical workers of malpractice.

Neurobiology,one of the important subject in life science frontier,comprises extensive and comprehensive contents.It is significant and essential for each discipline of medicine to offer this course.During last several years of teaching and practice,some methods,skills and ideas have been utilized and summarized.Modem medical education,by offering this course,will accord with the development concept of the transition from biomedicine to bio-psycho-social medical model,and this course will provide the substantial foundation for cultivating qualified medical students.

Erythropoietin(EPO) has an anti-apoptotic effect,and promotes the proliferation and differentiation of erythroid progenitor cells. Several studies have indicated that EPO can protect photoreceptor cells from the lightinduced retinal degeneration ;protect retinal neurons from ischemia-reperfusion injury and retinal ganglion cells after acute and chronic ocular hypertension; promote ganglion cell survival and axonal regeneration after optic nerve transaction; attenuate inflammation in multiple sclerosis optic neuritis; reduce the permeability of the retinal barrier and protect retinal neurons in diabetic retinopathy; enhance the stability of hypoxic retinal vessels in retinopathy of prematurity. Herein,we review the distribution of EPO and its receptor in retina,their expression in animal model of retinal diseases,and their effects and mechanisms in protection of retinal neurons and optic nerve.
