OBJECTIVETo investigate the clinical efficacy of cannulated screw fixation with percutaneous Poking reduction for the treatment of Sanders II, III calcaneal fracture.

METHODSFrom January 2012 to January 2014, 19 patients with Sanders II, III calcaneal fracture were treated with cannulated screw fixation with percutaneous Poking reduction. There were 14 males and 5 females, ranging in age from 19 to 58 years old, with an average age of (38.3 +/- 4.1) years old. The changes of Bohler angle and Gissane angle were measured and compared preoperatively and postoperatively to observe the recovery of the articular surface. The Maryland Foot Score was used to evaluate operation outcomes.

RESULTSAll the patients were followed up, and the duration ranged from 12 to 28 months with a mean of (22.3 +/- 5.3) months. The Bohler angle and Gissane angle were improved significantly after operation compared with those before operation (P < 0.05). The Maryland score was 83.2 +/- 8.4.

CONCLUSIONTreatment of calcaneal fractures with screw fixation with percutaneous Poking reduction has several advantages such as satisfactory outcome,less damage, fewer complications, quicker recovery, and shorter hospital stay,and it is one of the effective treatments for Sanders II and III calcaneal fractures.

Objective To establish an accurate method for estimating the indoor gamma dose rate from decorative stones.Methods Combining a room model with decorating conditions,the gamma dose rates and dose rate conversion factors (DCF) at 1 m above the floor in the room center were calculated with the Monte Carlo simulations,and the calculation results were verified through experiments.Based on the results,the limit of radionuclide contents in stone materials was further discussed.Results The DCF increases with the increase of area or thickness of decorative stones in the same room.The increase of DCF with the thickness of decorative stone is approximately linear.The DCF also increases with the area of decorative stones,but the increasing trend slows down.For the same decorative stones,the smaller the room,the larger the increase of gamma dose rate.Experimental results were consistent with the simulation results within ± 20％.Conclusions The increase of indoor gamma dose rate depends not only on the radionuclide contents,but also on the area and thickness of the decorative stones as well as the room size.The method used in this study can be used to estimate,more accurately than ever,the additional external exposure to residents due to decorative stones,and it provides a theoretical basis for revising the limit standard on radionuclide contents in decorative materials.

Objective To investigate the effects of lower limb training at different intensities on the recovery of walking function after stroke.Methods Thirty-six stroke patients were randomly divided into a 40-minutes of training group,an 80-minutes of training group and a 120-minutes of training group.Because of three missing followup cases,the final numbers of cases were 12,11 and 10 cases respectively.All of the patients received lower limb training based on regular rehabilitation therapy,but at the three different intensities:40 minutes,80 minutes or 120 minutes a day,five days per week,for 4 weeks.Walking function was assessed using the Holden functional ambulation categories (FACs) and the Fugl-Meyer assessment (FMA).These were carried out before treatment,and after two and four weeks of treatment.Results Before treatment,the average FACs of the three groups were (1.83 ±0.94),(1.73 ± 1.01) and (1.80 ± 1.03) respectively.Their average FMA scores were (19.17 ±5.52),(23.00±4.71) and (19.40 ±7.90).After two weeks of treatment,the average FAC in the 120-minutes training group was (3.30 ± 0.48),significantly higher than in the 40-minutes training group.After four weeks the average FACs in the 40-minutes,80-minutes and 120-minutes training groups were (2.67 ± 0.65),(3.18 ± 0.60) and (3.80 ±0.42) respectively.The differences between the 120-minutes group and the 80-minutes group as well as between the 80-minutes group and the 40-minutes training group were statistically significant.The average FMA scores of the three groups after four weeks were (25.08±4.46),(28.64±3.56) and (25.90±5.19) respectively.All the differences were significant compared with pre-treatment.There were no significant differences in FMA scores among the three groups after two weeks or four weeks of treatment.Before treatment,the proportion of patients able to walk independently in the 40-minutes,80-minutes and 120-minutes training groups were 16.7％,18.2％ and 20.0％.After two weeks the proportions had risen to 33.3％,36.4％ and 100％ respectively,so the results in the 120-minutes training group were significantly better.After four weeks of treatment the proportions of the three groups were 58.3％,90.9％ and 100％.All these improvements were significant compared with pre-treatment,but when compared with the 80-minutes training group,neither of the others showed a significant difference.Conclusions Intensive training can accelerate the recovery of walking function of patients after stroke and promote their ability to participate in daily activities.

Objective To determine the minimum alveolar concentration(MAC) of sevoflurane without body movement during laryngeal mask airway(LMA)intubation in premature infants less than 37 weeks of corrected gestational age undergoing total inhalation general anesthesia induction.Methods Twenty-one ASA Ⅰ or Ⅱ premature infants less than 37 weeks of corrected gestational age undergoing elective inhalation general anesthesia were enrolled in this study.At first,the general anesthesia induction was started by inhaling 6 ％ sevoflurane.After the premature infant lost consciousness,the end tidal sevoflurane concentration(ET-sev)was adjusted to the predetermined concentration and maintained stable for 15 min.After that,LMA was inserted.The up-anddown sequential allocation was used to determine MAC.The initial ETsev was 2 ％,which was increased or decreased by 1 gradient concentration in the next case according to the LMA insertion body movement response.The adjacent concentration gradient was 0.2％.The midpoint from th body movement response to non-body movement response was set as the balance point and the mean value of the concentrations of sevoflurane at all the balance points were calculated as MAC.Results The end tidal sevoflurane con centration without the body movement responses to LMA insertion was 1.71％.Conclusion The MAC of sevoflurane without the body movement responses to LMA insertion in premature infants less than 37 weeks of corrected gestational age is 1.71％,which is lower than that in the normal children and probably because imperfect central nervous system development in premature infants.
