The tumor stem cell theory supposed that tumor stem cells are the origin of tumor abnormal proliferation,invasion,metastasis,drug resistance and recurrence.As the theory is put forward,it redefines the functions of classic stem cells in tumorigenesis.It is a great event for recent studies on glioma initiating cells as brain tumor stem cells were identified and isolated successfully.A lot of evidence from experiments in vivo and in vitro demonstrates that brain tumor stem cells might play an important role in glioma tumorigenesis.In this review,we discuss the relationship between tumor stem cells and tumorigenesis,and the research on the correlation between brain tumor stem cells and glioma genesis.

ObjectiveTo observe the effect of comprehensive rehabilitation treatment on clinical nerve function deficiency (CNFD) and activities of daily living (ADL) of the patients with stroke. Methods45 stroke sufferers from different period were divided into three groups (1st group: in one month; 2nd group: one to six months; 3rd group: over six months). Before and after the comprehensive rehabilitation treatment was given, the CNFD, ADL and clinical effect were assessed.ResultsAfter comprehensive rehabilitation treatment, the CNFD of 1st group, and the ADL score of 1st group and 2nd group were improved significantly, and the 1st group's was better than the others. The total effective rate also increased in 1st and 2nd group. Conclusions Early rehabilitation treatment can improve the patient's neural motion function and the activities of daily living.

Objective To observe the application of angiotensin Ⅱ receptor antagonist valsartan in reducing minim albuminuria in earlier period of the diabetes and kidney disease.Methotis 36 patients Who administered angiotenain Ⅱ receptor antagonist valsartan 80～160nag,qd,for 8 weeks.Compared with symptoms before the treatment,the blood pressure,the amount of the urinary albuminufia,and observed the change of the empty stomach blood sugar,the saccharified hemoglobin,the triglyceride,the total cholesterol,the endogenous creatinine clearance rate,etc.Results After the treatment,the urinary albumin drops obviously(P＜0.01),While the blood pressure,the empty stomach blood sugar,the saccharified hemoglobin,the triglyceride,the total cholesterol and the endogenous creatinine clearance rate have no obvious change.There is no obvious side effect during therapeutic process.Conclusion The application of angiotenain Ⅱ receptor antagonist valsartan can reduce the amount of the urinary albumin,is the effective way in treating the earlier period of the diabetes and kidney disease.

Purpose　To investigate the diagnostic valuation of Gd-DTPA enhancement MRA in intracranial occuping and vescular diseases. Methods　Gd-DTPA MRA（63 cases）, MRA without Gd-DTPA（16 cases）as a control group was performed with Elscint Prestige 2.0T MR,MRA. 56 cases were proved by operation or pathology, 7 cases were proved by clinical observation. Results　The shape of aneurysms, the feeding arteries, the draining veins of AVM and diploe angioma, the feeding arteries of occuping were clearly showed by Gd-DTPA enhancement MRA and were not showed by MRA without Gd-DTPA.There wasn't much difference between cavernous angioma with Gd-DTPA enhancement MRA and MRA without Gd-DTPA in the shape and blood supply of cavernous angioma. Conclusion　Gd-DTPA enhancement MRA is useful and worthy for showing blood circulation of intracranial occuping and vascular diseases.

Objective To observe the changes of plasma urotensinⅡ(UⅡ)、PAMP(proadrenomedullin N-terminal peptide)and ANP(atrial natriuretic peptide)levels in patients with congestive heart failure (CHF) and to illustrate clinical significance of these changes.Methods 52 patients with CHF and 20 age and gender-matched control subjects were studied.Plasma UⅡ.PAMP and ANP levels of 52 patients with CHF and 20 control subjects were measured by radioimmunoassay.Heart function of all study subjects were mensurated by ultrasound cardiography.Results The plasma UⅡ levels were significantly lower in patients with CHF than that in control subjects [(1.48?1.05) vs (4.28?1.21) pg?mL -1,P
