Objective To investigate the therapeutic effect of the complicated fracture of tibial plateau treated by open reduction and internal fixation. Methods Surgical treatment in 68 cases with complicated fractures of the tibial plateau were analyzed retrospectively, T type plate, L type buttress plate, double plates, anatomical plate,locking plate and less invasive stabization system were adopted for different fractures,iliac or artificial bone grafted in the reconstruction of bone defect after the depression replaced. The time of operation and the effect of functional exercise in the postoperative patients to recover the function of the knees were analyzed at the same time. Results 52 patients of 68 cases were followed-up. Based on Rasmussen rating system,the recovery of knee joint function were excellent in 42cases(67%) ,good in 12 cases(19%) ,fair in 6 cases(10%) and poor in 2 cases(4%) ,the excellent-and-good rate was 86%. Conclusion Surgical treatment of the complicated fractures of the tibial plateau depended on the kind of fracture, therapeutic principles by stages. Moreover, bone grafte after the depression replaced in bone defect was neeassary,good internal fixtion oould meet functional exercise,soft tissue injuries like ligament and meniscus should be well treated,follow the principles of early exercise and delay weightbearing.

Objective To characterize emotional memory impairment in untreated patients with Parkinson' s disease (PD) in the early stages of the disease. Methods Emotional memory tasks using standardized sets of emotional pictures including positive, neutral and negative valence were tested in 33 untreated patients with PD in the early stages and 31 healthy controls matched with age, sex, and education.Results Compared with the healthy adults (13.4 ± 1.4), PD patients had significant loss of negative valence picture memorizing ( 8. 9 ± 1.0; t = - 14. 87, P ＜ 0. 01 ).There was no significant difference between PD patients and normal controls in positive ( 11.8 ± 1.0 vs 12. 4 ± 2. 2 , t = - 0. 95 ) and neutral (7.9 ± 1.4 vs 8.2 ± 1.3, t = - 0. 89) valence picture memorizing ( both P ＞ 0. 05 ). ConclusionThe emotional memory for negative valence pictures is impaired but the emotional memory for positive and neutral is relatively spared in early PD patients without treatment.

Objective To observe the effects of levodopa on verbal and spatial working memory in elderly patients with Parkinson's disease (PD).Methods The modified Smith working memory software were applied to study the verbal and spatial working memory in 32 PD patients before and 8 weeks after treatment with levodopa and benserazide hydrochloride tablets.The results of PD patients were compared with those in 32 normal controls matched for age,sex and education.Results The correct rates of phonological verbal and coordinate visuospatial working memory were significantly lower in the PD patients without treatment than in the normal controls (both P＜0.01).The correct rates of semantic verbal and categorical visuospatial working memory had no significant differences between the PD patients without treatment and the normal controls (both P＞0.05).The correct rates of phonological verbal working memory and coordinate visuospatial working memory were significantly higher in the PD patients after administration of levodopa and benserazide tablets than in PD patients without treatment [(88.6±6.5)％ vs.(82.1 ± 6.6)％,(84.2±8.8)％ vs.(75.2±8.9)％,respectively,both P＜0.01],but there were no significant differences in the correct rates of semantic verbal working memory and categorical visuospatial working memory between the above two groups (both P＞0.05).The correct rates of phonological verbal,semantic verbal,coordinate visuospatial and categorical visuospatial working memory were negatively correlated with the course of disease,and had no correlations with age and the degree of education.Conclusions Levodopa can improve the functions of phonological verbal working memory and the coordinate visuospatial working memory,but has no effect on the semantic verbal working memory and the categorical visuospatial working memory.It is postulated that dopamine replacement therapy may have double dissociable effects on the different working memories.

Objective To evaluate arterial stiffness in middle-age and elderly patients on the treatment of hemodialysis and to investigate the risk factors of arterial stiffness. Method A total of 87 in middle-age and elderly patients on the treatment of hemodialysis were enrolled. The distensibility coefficient (DC) of the common carotid artery was evaluated by an ultrasonic phase-locked echo-tracking system. Serum albumin, total cholesterol (TC), high density lipoprotein (HDL), low density lipoprotein (LDL), triglyceride (TG), glucose, creatinine,calcium, phosphorus, and intact parathyroid hormone (iPTH) were determined with well established methods. Results The ages of 87 patients ranged from 45 to 81 years, and the duration of treatment with hemodialysis was varied from 3 to 204 months . The carotid DC was ( 13.39 ± 5.32 ) × 10-3/kPa in middle-age and elderly patients on hemodialysis. In stepwise multiple regression analysis, systolic blood pressure (β = -0.349, P ＜ 0.001), age (β=-0.323, P ＜ 0.001), diabetes (β =-0.195,P = 0.027), and serum calcium (β =-0.276,P =0.002) were independently correlated with carotid DC. Conclusions Systolic blood pressure, age, diabetic,serum calcium were independent determinants for arterial stiffness of carotid artery in middle-age and elderly patients on hemodialysis.

Objective To explore the characteristics of event-based prospective memory (EBPM) and time-based prospective memory (TBPM) impairments in patients with Parkinson's disease (PD). Methods EBPM and TBPM were examined in 87 PD patients and 85 healthy controls. And both of them were divided into two groups: aged group (≥60 years old) and non-aged group (＜60 years old). Results (1) The scores of EBPM were significantly lower in aged PD patients and non-aged PD patients than in age-matched control groups [(2. 5±0. 4) vs. (5.8± 1.3),(3.9±2.4) vs. (6.3±1.5), both P＜0. 01]. There were no significant differences in the scores of EBPM between aged PD patients or non-aged PD patients and their age-matched control groups [(3.6±0.5) vs. (3.8±0.8), (4.8±0.9) vs. (4.9±0.9), both P＞0.05]. (2)The Hoehn-Yahr grade in PD patients was significantly correlated with scores of EBPM, but not with scores of TBPM.Conclusions The patients with PD have an impairment in EBPM, but not in TBPM. The impairment of EBPM may be related to the disease severity of PD.

BACKGROUND:Artificial total disc replacement is one treatment of low back pain in recent years, but the report on the effect of disc replacement on lumbar sagittal plane is rare. OBJECTIVE:To analyze the effect of lumbar disc replacement on lumbar lordosis. METHODS:Retrospective analysis of radiographic data of 17 patients who underwent lumbar disc replacement for single segment degenerative disc disease was carried out. Data measurement included preoperative and postoperative lumbar lordosis, diseased segmental lordosis and lumbar intervertebral angle. RESULTS AND CONCLUSION:Al the 17 patients were fol owed-up for more than 12 months. Lumbar disc replacement was performed at L4-5 segment in three cases and L5-S1 segment in 14 cases. The average diseased segmental lordosis and lumbar lordosis were increased significantly after replacement when compared with those before replacement (P<0.05);the lumbar intervertebral angle was increased after replacement when compared with that before replacement, but the difference was not significant. The results indicate that lumbar disc replacement for the treatment of single segment degenerative disc disease can increase the lumbar lordosis and diseased segmental lordosis, which can help to improve the lumbar sagittal balance. The postoperative lumbar intervertebral angle has no correlation with the implant angle of the prosthesis on the replace segment.
