The detection wavelength was set at 280 nm,and the column temperature was 30 ℃. The samples size was 10 μl. RESULTS:TLC spectrum showed that the spots of F. arctii concentrated granules and arctiin reference medicinal material had the same color;the linear range of arctiin was 0.5-12.5 μg(r=0.999 8)with the average recovery of 98.41%(RSD=0.81%, n=9). The RSDs of precision,stability,repeatability tests were no more than 1.0%. CONCLUSIONS:The method is feasible and reproducible,and can effectively control the quality of F. arctii concentrated granules.

Objective To investigate the efficacy of progressive resistance exercise for improving the lower limb motor function of hemiplegic stroke patients. Methods Eighty-nine hemiplegic patients were randomly divided into a treatment group (n =46) and a control group ( n = 43 ) . Both groups received routine rehabilitation training, while the treatment group also undertook progressive resistance training. The control group received extra quadriceps femoris training. Before and after the treatment, motor function was evaluated with the Fugl-Meyer lower limb assessment, functional ambulation category (FAC) classification and the modified Barthel index (MBI). Results Before intervention, there were no significant differences between the two groups in any of the assessments. Four weeks later, all the assessment scores obtained with the Fugl-Meyer lower limb assessment, FCA classification and MBI in the treatment group were significantly better than those in the control group. Conclusion Progressive resistance training combined with routine rehabilitation treatment can improve motor function in the lower limbs, ambulation and ability in the activities of daily living of hemiplegic patients after stroke.

Objective To investigate the levels of interleukin-15(IL-15) in children with acute leukemia and contribute to understand their function on acute leukemia about the process.Methods Every group of acute lymphocytic leukemia(ALL),acute nonlymphocytic leukemia(ANLL) or non-leukemia group had 20 children who did not receive any treatment. Peripheral blood of every group and 20 other healthy children were aspirated .The levels of IL-15 in serum was analyzed by enzyme linked immunosorbent assay (ELISA).Results The levels of IL-15 in ALL group,ANLL group, non-leukemia group and healthy children were (34.37?2.8) ng/L, (29.61?3.2 )ng/L, (117.54?3.9) ng/L, (122.23?4.2) ng/L. Compared with the levels of the healthy group or the non-leukemia group, the difference of ALL or ANLL was signicant in statistics(q=3.95,4.03 Pa0.05).Conclusion Detection of serum IL-15 levels may have clinical significance in judging the anti-tumor immune condition in children with leukemia.

OBJECTIVE: To investigate clinical application of head impulse test with video recording eye movements in the diagnosis of vertigo. METHOD: The video head impulse test(vHIT) was used to measure the eye saccades and velocity gain in 95 patients with vertigo which were divided into two groups, peripheral vertigo (47 cases) and central vertigo(48 cases); the characteristics of eye saccades and velocity gain of six semicircular canals in different patients with vertigo were analyzed, and were compared between the two groups. RESULT: The vHIT result in patients with peripheral vertigo: in 22 patients (23 affected ears) with Meniere's disease, 21 ears were abnormal (91. 3%); the vHIT results in 4 patients with vestibular schwannoma, 2 patients with vestibular neuritis, 5 patients with delayed endolymphatic hydrops, 6 patients with sudden hearing loss accompanied vertigo, and 8 patients with vestibular dysfunction, were abnormal with correct saccades and/or lower velocity gain of vHIT. The abnormal vHIT results were also found in 35 of 48 patients (72. 9%) with central vertigo, which including posterior cerebral circulation ischemia(7 patients), cerebral infarction/stroke(6 patients), and dizziness with vertigo(17 patients) and others(18 patients). Abnormal rate of vHIT in patients with peripheral vertigo was 95. 7% (45/47), which was significantly higher than that (72. 9%) in patients with central vertigo. CONCLUSION It is easy to perform the vHIT which without adverse reactions. We can record high-frequency characteristics of vestibular-ocular reflex among six semicircular canals through vHIT. The vHIT results which show the function of vestibular ocular reflex in different diseases with vertigo, can help discriminate peripheral vertigo from central vertigo, and it is a practical assessment method for vertigo.
