Comparison of clinical efficacy of two different pin arrangements for external fixation of femoral neck fracture / 中国骨伤

OBJECTIVE@#To retrospectively analyze the clinical efficacy of external fixation in the treatment of femoral neck fracture with two different pin layout.@*METHODS@#From April 2000 to April 2018, 140 cases of femoral neck fracture were treated with closed reduction and percutaneous pin external fixation, among them 121 cases were followed up for more than 1 year, including 31 cases in traditional group, 12 males and 19 females, aged 45 to 74(65.4±8.4) years;90 cases in modified group, 39 males and 51 females, aged 12 to 75 (64.5±7.8) years. In traditional group, the first needle was put on the femoral talus, the second and third needles were put under the tension line, and the three needles were not on the same line in the lateral phase; in modified group, the first needle was drilled into the lateralcortex of the femur, obliquely penetrating the distal and proximal end of the femoral talus fracture, and the other two needles were drilled into the medial cortex of the femoral neck and the femoral talus, respectively. The operation time, hospital stay, postoperative ambulation time, femoral neck shortening rate, fracture healing time, fracture healing rate and femoral head necrosis rate of the two groups were observed and compared. Harris hip function score was used one year after operation.@*RESULTS@#These 121 patients were followed-up, the follow up time of traditional group was 13 to 45(30.5±11.4) months;the follow-up time of modified group was 14 to 120(34.5±12.5) months. There was no significant difference in operation time, hospital stay and femoral head necrosis rate between two groups (@*CONCLUSION@#Compared with the traditional group, the modified group has the advantages of lower femoral neck shortening rate, shorter fracture healing time, higher fracture healing rate and higher Harris hip function score.

Study on sleep disorders in patients with Parkinson' s disease by polysomnogram / 中华神经科杂志

Objective To observe the polysomnographic manifestation of sleep disorder and the characteristics of sleep architecture in patients with PD.Methods 42 patients with PD and 40 normal controls underwent night polysomnography.The parameters of sleep architecture and progress in two groups and video-monitoring features were analyzed.Results According to PSG recordings,the incidence of difficulties in the initiation of sleep(73.8%),fragmented sleep(59.5%),excessive daytime sleepiness (46.1%)were respectively increased in PD patients group than that in controls(all P5)、 ESS were increased(P=0.022,0.000,0.007, 0.001,0.000,respectively).SOREMPs occurred in 6 patients(14.3%)in PD group,but didn't oecure in controls.In PD group REM without atonia(RWA)was demonstrated in 36 patients(85.7%),RBD in 19 patients;in control group,however,REM in 6 and RBD in 2 separately.The statistics analysis showed the incidence of RWA(85.7%)and RBD(45.2%)in PD group was significantly higher than that in control group(P
