Transcranial magnetic stimulation (TMS) is a non-invasive technique that can activate cortical motor areas and the corticospinal tract without causing the subject discomfort. Since TMS was introduced, numerous applications of this technique have been developed for the evaluation of neurologic diseases. They allow the evaluation of cortex excitability and motor conduction in the central nervous system and have been proved useful in monitoring motor abnormalities and the recovery of motor function. TMS also gives informations on the pathophysiology of the processes underlying the various clinical conditions and contribute to investigate the mechanisms of diseases. In addition, therapeutic use in depression, Parkinson's disease, epilepsy, spinal cord injury and stroke has raised great interest over the past decade. Theapplication of TMS has great potential both as an investigational and as a therapeutical tool in neurology and psychiatry. However, as an infant techniology, there should be further investigation and large randomized trials to be conducted.

Objective To compare the effect of tension-free vaginal tape (TVT) and vaginal reconstructive surgery (VR) on women with severe genital prolapse and stress urinary incontinence.Methods 43 patients with stage I or II vaginal anterior defect and stress urinary incontinence were assigned to TVT group(21 patients) and VR group (22 patients) . Results Maximum quantity of urine, pressure of detrusor at maximum quantity of urine, and abdominal leakage point pressure occured significantly in TVT group after operation(P<0.05). Postoperative satisfaction rate were higher in TVT group(P<0.05). Conclusion TVT is more effective to improve the quality of life in women with stress incontinence.

The contents of chrysophanol. free or comhined. and the peak heights of the antihepatotoxic components in the crude and processed seeds of Cassia tora L,. and in their decoctions were compared by HPLC. The content of free chrysophanol in processed seeds increased. and the combined chrysophanol and the antihepatotoxic components decreased. But those present in the decoction were just vice versa. The methods described can beused for further studies in the processing of C. tora

Objective To study the clinical characteristics by using CT, MRI and biochemistry test on the X linked adrenoleukodystrophy (X ALD) Methods The clinical,neuro imaging and determinations of plasma very long chain fatty acids (VLCFAs) of 12 cases with X ALD were analysed Results The main clinical features consisted of the childhood onset,progressive auditory, visual and/or intelligent impairment, behavioural changes,epileptic seizures and melanodermia. CT or MRI scans demonstrated that the demyelinating lesions were located on the bilateral white matter in occipital,posterior parietal and temporal lobes.The levels of hexacosanoic acid (C 26:0 ) and the ratio of C 26:0 to docosanoic acid (C 22:0 ) were increased. Conclusions ALD is an inherited disease as an X linked trait.The childhood X ALD is characteristiced by progressive auditory, visual and intelligent deterioration.The abnormalities of CT or MRI scan and the levels of the plasma VLCFAs are crucial to the diagnosis of X ALD.

Objective:To produce a fusion protein(ICOS-Ig)between extracellular portion of human ICOS and Fc portion of mouse IgG 2a and study on its biological activity.Methods:cDNA encoding the extracellular domain of human ICOS was prepared by RT-PCR from the RNA of the stimulated human peripherial blood mononuclear cells. The Fc portion of mouse IgG2a was cloned by PCR from the vector that contains the sequence-encoding Fc portion of mouse IgG2a.Two resulting amplified PCR products were ligated into a secrection mammalian expression vector, pSecTag2/Hygro A. The recombined vector was transfected into CHO cells by lipofectamine2000.Results:RT-PCR demonstrated the integration and mRNA synthesis of fusion gene. ELISA and Western blot analysis showed the expression of ICOS-Ig and its molecular weight was between 43-66 kD, its concentration was 5-25 ?g/ml. FACS analysis assured that ICOS-Ig had ligand specific binding activity. Addition of ICOS-Ig to MLR resulted in inhibition of T-cell proliferation and IL-2,IFN-? secretion.Conclusion:The fused gene ICOS-Ig was constructed and expressed successfully. It had the bioactivity of inhibition of T cell proliferation and cytokine secretion.

Protein-protein binding is the basis of virus and host cell interactions. With the application of technology of studying protein interactions, more knowledge of replication and pathogenesis of hepatitis C virus (HCV) was acquired. Non-structure protein 5B(NS5B) of HCV is a kind of viral protein, which plays an important role in replication of HCV. However, the effect of NS5B is not clear. To investigate the biological function of NS5B, we performed yeast two hybrid to look for proteins in hepatocytes interacting with NS5B. We constructed NS5B bait plasmid by cloning the gene of NS5B into pGBKT7, then transformed it into yeast AH109(a type). The transformed yeast was mated with yeast Y187(? type)containing liver cDNA library plasmid in 2?YPDA medium. Diploid yeast was plated on synthetic dropout nutrient medium (SD/-Trp-Leu-His-Ade) containing x-?-gal for screening. Thirty-three colonies were selected and sequenced. Among them, two colonies were new genes with unknown function. The preliminary successful cloning of gene of protein interacting with NS5B paved the way for the study of the physiological function of NS5B and its associated protein.

The strategic cost management of the hospital means setting the cost management of the hospital in the realm of strategic management and analyzing the hospital and its cost behavior and structure from a strategic level so as to create advantages in competition, attain the goal of adapting the hospital to the continuously changing environment and facilitating stralegic management. Strategic cost management is characterized by a protracted, overaU, extensional and innovative nature and methods for it include value chain analysis, strategic positioning analysis, cost agent analysis and many others. Clarifying the goals of strategic cost management, selecting different strategies according to strategic cost information, perfecting the cost management of the hospital and enhancing cost awareness, and giving play to the functional role of economic management personnel are some of the prerequisites for the hospital to implement strategic cost management.

OBJECTIVE:To establish a method for the determination of4major caffeine metabolites and to discuss the significance of which in the evaluation of the activity of drug-metabolizing enzyme CYP1A2.METHODS:The caffeine metabolites in the urine like5-acetylamino-6-formamido-3-methyluric acid(AFMU),1-methyluric acid(1U),1-methylxanthine(1X)and1,7-dimethyluricacid(17U)were determined by RP-HPLC gradient elution method,the ratios of metabolins(AFMU+1X+1U)/17U was calculated,the frequency distribution histogram was drawn and the activity of CYP1A2was evaluated.RESULTS:The mean value of the ratio of the metabolins in the subjects was4.27,which was in normal distribution.CONCLUSION:The method is simple,accurate and rapid,which is suitable for the determination of caffeine metabolites in urine and the study of the activities of CYP1A2.

Objective To determine the long-term outcomes of renal interventional therapy in patients with renal artery stenosis. Methods One hundred thirty-four consecutive patients reveived renal stenting in our hospital. The changes of BP and serum creatitine were measured 24 hours after the procedure and during the first and second year of follow-up. Results All procedures were performed successfully. The mean serum creatitine level increased [(109.8?24.6) ?mol/L vs (99.4?27.8 baseline level) ?mol/L] and the glomerular filtration rate decreased [(57.6?19.3)mL/min vs (68.5?18.9) mL/min] significantly after the procedure. However during the first and second year of follow-up, the serum creatitine level returned to the pre-procedure level. Sixty-four patients attained benefit of BP improvement at about 6 months after renal artery stenting. The mean systolic pressure 6 months after the procedure was (148.6?22.6) mm?Hg (1 mm?Hg=0.133 kPa), which was significantly lower than the baseline level. During the first and second year of follow-up, there were 56 patients (50.6%) and 50 patients (49.6%) achieved BP improvement from renal stenting respectively. Conclusion Renal stenting is efficient and has satisfactory long-term outcomes in treating renal artery stenosis.
