1.Advance in Investigation of Transcranial Magnetic Stimulation (review)
Chinese Journal of Rehabilitation Theory and Practice 2006;12(10):879-882
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.

Chinese Journal of Rehabilitation Theory and Practice 2004;10(7):432-433
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 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 investigate the stability of injectable pantoprazole sodium in 4 kinds of infusions.METHODS: A HPLC method was adopted in this determination, the content change of injectable pantoprazole sodium was determined within 4 hours' mixing with 4 kinds of infusions and its change of color was observed; meanwhile the effects of pH value, potassium,magnesium,calcium ions on the stability of injectable pantoprazole sodium were investigated.RESULTS:No obvious changes were noted in terms of contents, appearances, pH value, UV - absorption maximum wavelength for the injectable pantoprazole sodium solution within 4 hours either in 4 kinds of common infusions or in potassium,magnesium,calcium ions water solutions.It was extremely unstable when pH value of pantoprazole sodium solution was lower than 7.0;when its pH value was 7.0, its color became yellowish yet without obvious loss of content; it is stable within 4h when its pH value was above 8.0.CONCLUSIONS:Injectable pantoprazole sodium remains stable within 4 hours either in 4 kinds of common infusions or in potassium, magnesium, calcium ions water solutions, the pH value has a great influence on the stability of pantoprazole sodium solution.

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.

AIM: To study the visual quality, dry eye and biomechanical stability of patients with myopia and astigmatism after different corneal refractive surgeries. ·METHODS: A total of 986 patients with myopia and astigmatism were selected as the research object in our hospital from July 2015 to July 2016, according to the operation mode of the selection of the research object, the 986 patients were randomly divided into small incision lenticule extraction ( SMILE) group, femtosecond laser in situ keratomileusis ( FS-LASIK ) group, sub-bowman-keratomileusis ( SBK ) group and laser-assisted in situ keratomileusis ( LASIK ) group. The postoperative visual quality was determined by comparing the diopter, uncorrected visual acuity ( UCVA ) , best corrected visual acuity ( BCVA) and high-order image difference of 25d, 90d. The postoperative dry eye condition was determined by comparing the postoperative tear secretion test ( Schirmer Ⅰ test ) , tear film rupture time ( BUT ) and fluorescence staining ( FS) . The biomechanical stability of the patients was determined by comparing the corneal hysteresis ( CH ) and corneal resistance factor ( CRF ) values of the four groups. ·RESULTS: The diopter, UCVA, BCVA and high-order aberration comparison of FS-LASIK group, SBK group and LASIK group between before and after surgery, showed no significant difference ( P>0. 05 ); on diopter, BCVA, UCVA, there was no significant difference between before and after surgery in SMILE group (P>0. 05), but statistical significance difference on high order aberration (P<0. 05). The BUT and FS value of the four groups decreased obviously after operation, and the difference was statistically significant (P<0. 05). In LASIK group SIt after operation significantly decreased, with statistically significant compared with that before operation ( P <0. 05). After operation, CH and CRF of the four groups decreased with significant differences (P<0. 05). ·CONCLUSION: SMILE, FS-LASIK, SBK and LASIK are equally safe, effective and stable in the treatment of myopia and astigmatism.
