RBC, plasma and hair Mn levels have been measured in 38 children with Keshan disease from the Chuxiong district of Yunan province and were compared with that of 35 healthy children. After logarithmic, transformation, normal distribution of Mn levels of RBC, plasma and hair had been presented. The geometric means of the RBC, plasma and hair Mn content of the patients were 1.22?g/g(dry basis), 0.16?g/ml and 8.76?g/g respectively. In normal subjects, the means of RBC, plasma and hair Mn were found to be 0.59?g/g (dry basis), 0.13?g/ml and 2.57?g/g. The children with Keshan disease had higher Mn levels than controls. (P

BACKGROUND: Conventional means in treatment of distal tibiofibular syndesmosis disruption include plaster cast or splint immobilization as external fixation and internal fixation using screws, and bone bolts or plates;however, some disadvantages such as unstable fixation and uncertain fixation exist.OBJECTIVE: To observe the primary clinical curative effect of newly self-developed fixation, Hook-plate fixation (HPF), for distal tibiofibular syndesmosis disruption and its biochemical characteristics of HPF.DESIGN: Self-control observation.PARTICIPANTS: We recruited 23 patients with sustaining abruption of lower tibiofibular ligament union with fibular fracture who received treatment in the Department of Orthopedics, Affiliated Hospital of Yangzhou University Medical College, between October 2001 and March 2004. According to the Lauge-Hansen classification system, there were 11 cases of supination-lateral rotations, 7 cases of pronation-lateral rotations and 5cases of pronation-abductions. Among them 14 had bimalleolar fractures and 9 had trimalleolar fractures.METHODS: HPF was used on the 23 patients with distal tibiofibular syndesmosis disruption. Radiographs were taken routinely. Talocrural joint function exercise was recommended at week 1 and partial weight bearing was allowed 2 months later. Functions were evaluated according to modified Mazur's criteria (excellent, good, fair and poor).MAIN OUTCOME MEASURES: ①Healing time and function ev aluation after operation for distal tibiofibular syndesmosis disruption. ② Adverse events and side effectsRESULTS: Totally 23 patients entered the result analysis, with the mean of 11 months' follow-up. ①Results of healing time and function evaluation in the patients after operation for distal tibiofibular syndesmosis disruption: The healing time of fracture ranged from 12 to 18 weeks: 16 cases were excellent, 5 good, and 2 fair. ② Adverse events and side effects:There was no separation of the tibiofibular space, the distance between medial malleolus or lateral malleolus and anklebone was symmetrical.There was no mobilization or rupture of the internal fixation after operation.CONCLUSION: HPF is applied in treating distal tibiofibular syndesmosis disruption. It causes no postoperative complications, and can recover the ankle joint function with stable internal fixation and good biomechanical features.

Objective To investigate and compare the effect of two kinds of transparent dressings in the use of fixed intravenous indwelling needle in restless patients in emergency first aid. Methods A total of 160 restless patients who were required to use intravenous indwelling needle were randomly divided into conventional dressing group and 3M dressing group by random digits table method, 80 patients in each group. The medical transparent dressings(Specification:6 cm × 7 cm) were used for the patients of conventional dressing group, and 3M dressings(Specification:6.5 cm×7.0 cm ) for 3M dressing group. The fixity time, number of cases intravenous indwelling needle detached, replaced time of transparent dressing, number of crimping cases were compared. Results For the conventional dressing group, fixity time was (19.67 ± 7.02) h, replaced time was (18.92 ± 6.58) h, 15 detached cases and 24 crimping cases happened. While for the 3M dressing group, fixity time was (41.64±17.79) h, replaced time was (41.11 ± 17.76) h, 4 detached cases and 7 crimping cases happened. The difference was statistically significant(t=-10.27,χ2=7.23, t=-10.48,χ2=11.56, all P<0.05). Conclusions 3M transparent dressing is suggested in fixing intravenous indwelling needle in restless patient in emergency first aid. It can ensure the use of intravenous indwelling needle during the period, effectively prevents the needle from detaching due to its good fixation effect.
