BACKGROUND: An epidemic outbreak of poliomyelitis occurred in Pizhou City, Jangsu Province, 15 years ago. It is important to appraise the daily living and function of those survived children.OBJECTIVE: To investigate the physical status of the survived children and propose appropriate suggestions on rehabilitation.DESIGN: Case-based cross-sectional study based on patients.SETTING: Department of Rehabilitative Medicine of First Hospital Affiliated to Nanjing Medical University.PARTICIPANTS: Totally 545 patients with poliomyelitis sequela, which was onset in 1989, were found in Qizhou, and 333 of them were randomly selected from the local"New Hope" nursing house and its surrounding areas.All patients were assayed in one week.METHODS: The survey included 333 polio victims in the nursing house or from the surrounding areas. The study was conducted by five research groups, with two physiatrists and one therapist in each group. Assessment included muscle strength, joint rang of motion, limb deformities, activities of daily living, previous surgical interventions and orthosis. The distance was measured from the anterior superior iliac to medial malleolus and from nave to the medial malleolus, respectively. Anatomic length and functional length were also measured.MAIN OUTCOME MEASURES: Major outcomes included the forms,shapes, or functions of foot, pelvic, hip, knee and ankle joints.RESULTS: According to intention-to-treat analyses, 333 patients with poliomyelitis sequela entered the final analysis. Most of them aged from 15 to 17 years old, which accounted for 97%. Totally 135 patients(40.5% )walked independently and 148 (44.4%) walked with-orthsis and/or crutches. The discrepancy was between 0. 5 cm to 13.0 cm. Patients with paraplegia were 112(33.6% ), which was lesser than those with monoplegia (211, 65.8% ). There were 3 cases with quadriplegia and 2 cases with upper limb involvement. Another 46 sufferers had already underwent the scoliosis prthomorphia. There were 254 subjects with orthosis, including 110 knee ankle feet orthosis for both legs and 131 knee ankle feet orthosis for one leg,with 62 at left and 79 at right. Only three ankle-foot orthosis were employed.CONCLUSION: Besides the factor of muscle strength, limb teratism is the key factor that causes walking disorders. Physical functions maybe improved through surgical intervention, orthosis modification, and rehabilitation training. Every child who received survey required further rehabilitative therapy. A multi-disciplinary team is essential to achieve a better outcome.

Objective To explore the effect of bio-resonance on walking efficiency in healthy youths. Methods Ten young male participants were involved in this study (age 16 ± 2 years, height 1.73 ±:0. 1 m and weight 56. 1 ± 7 kg). The time-space data were collected using a motion analysis system, and oxygen cost was meas-ured with a Cosmed K4b2 portable gas analysis system. Walking at a self-selected, comfortable walking frequency was recorded through three dimensional gait analysis. Each participant walked at 100% , 80% and 120% of their comfortable walking frequency. Results The average 100% , 80% and 120% comfortable walking frequencies were 107.60 ± 1.78, 85.80 ± 7.45 and 128.60 ±10.46 steps/min, respectively. Oxygen consumption at the three frequencies was significantly different (P≤0.01), and the oxygen costs were 0. 140 ± 0.011, 0. 193 ± 0. 049 and 0. 192 ± 0. 035 ml/m/kg, respectively. Above or below the self-selected pace, oxygen cost increased significantly (P ≤0.05). Conclusion There is an inherited bio-resonance in human walking, and walking with this natural rhythm is reflected in the lowest oxygen cost. Any change from the natural walking rhythm may result in increased en-ergy expenditure and decreased efficiency.

In the presence of silver ion, Mn2+ could be electro-oxidized to potassium hypermanganate in phosphoric acid solution, which could effectively react with pyrocatechol in acid solution and luminol in sodium hydroxide solution to produce chemiluminescence. On the basis of this, a novel indirect approach for the detection of Mn2+ was established. The effect of silver ions on the electrochemical oxidation of Mn2+was studied. when 1. 5 ×10-5 mol/L Ag+ and 0. 01 mol/L phosphoric acid solution were used in the process of electrochemical oxidation, the CL intensity could be up to the maximum value after the above solution was electrolyzed for 2 min. The relation of CL intensity and Mn2+concentration in the solutions at different pH and the selectivity were also investigated. when the pyrocatechol was used as luminescent reagent in the acidic medium, the CL intensity was linearly to the Mn2+concentration in the range of 1. 82×10-7-7. 27×10-5 mol/L with excellent selectivity. Common ions had little interferences in the determination of Mn2+. The method was successfully applied to the determination of Mn2+ in surface water and drinking water with satisfactory results.
