Objective To explore the effect of cilazapril on motor and cognitive function in hypertension with brain stroke. Method 42 hypertensive patients with stroke were divided into cilazapril treatment group(22 cases) and traditi onal treatment group (20 cases). The cilazapril group was treated with Inhibace 2.5 mg~5 mg daily. The traditional group was treated with nifedipine and/or di uretic. The blood pressure was measured twice a day during the treatment course. The activity of daily living (ADL), motor and cognitive function were assessed with Barthel index, Fugl-Meyer and MMSE assessment respectively before and 6 we eks after treatment. Results There were no difference between the two groups on blood pressure effectiveness, but blood pressure was more stable in the cilazapril gro up. Improvement of ADL and lower limb motor function in cilazapril treatment gro up were improved significantly than those of traditional treatment group(P<0.05). Although there was no difference between the two groups in the total value of cognitive function assessment, but the directional ability and memory function in group wa s higher than those in traditional group (P<0.05). Conclusion Cilazapril can decrease blood pressure steadily and can improve the activity of daily living and cognitive function in stroke patients.

BACKGROUND:It is a clinical difficult in the treatment of osteonecrosis with joint preservation, and to solve this problem, a variety of bone graft substitutes are at the exploration stage. OBJECTIVE:To evaluate the clinical outcome of lightbulb operation with porous bioceramic β-tricalcium phosphate in a consecutive series of patients with osteonecrosis of the femoral head. METHODS:From January to December 2008, 58 patients (88 hips) who had undergone lightbulb operation with porous bioceramic β-tricalcium phosphate were involved in this study. Al patients were evaluated both clinicaly and radiographicaly at postoperative 3, 6, 12 months and annualy. Functional improvement was assessed with the Harris hip score. RESULTS AND CONCLUSION: Among these patients, 56 patients (85 hips) were folowed up for 2-5 years. According to the ARCO staging system, there were 27 hips of stage II, 40 hips of stage IIIa, 18 hips of IIIb. According to the hospital’s classification, type C was in 4 hips, L1 in 15 hips, L2 in 28 hips, and L3 in 38 hips. According to the Harris hip score system, excelent outcome was in 55 hips, good in 12 hips, fair in 5 hips and poor in 13 hips. Nine of 11 patients who failed to preserve their own joints were subjected to hip replacement. The  mean preoperative and postoperative Harris scores were 61.2 and 85.3, respectively, with a mean improvement of 24.1 points (P < 0.001). All hips were radiologically stable, with no progress of osteonecrosis, and bone density in the bone graft area increased obviously. The replacement time of porous bioceramic β-tricalcium phosphate was 1-1.5 years. These findings suggest that the porous bioceramic β-tricalcium phosphate provides an option to treat osteonecrosis of the femoral head with satisfactory clinical outcomes, and profits the repair and reconstruction of femoral head osteonecrosis. When in the lateral column of femoral head, the porous bioceramic β-tricalcium phosphate can play a supporting role in the lateral column of the necrotic area, and further prevent collapse, which is suitable for patients with osteonecrosis of the femoral head, especially for those with joint preservation.

Objective To evaluate the early and middle-term results of in-situ single-screw fixation and subtrochanteric osteotomy of femur with external fixator for slipped capital femoral epiphysis(SCFE).Methods From June 1998 to July 2008, eleven patients (12 hips) with SCFE were treated, including 7males (8 hips) and 4 females (4 hips) with an average age of 14.3 years (range, 9-18). The average BMI was 31.1 g/m2. According to the Southwick measurement, mild (<30°) in 6 cases (7 hips), moderate (30°-50°) in 2 cases (2 hips), and severe (>50°) in 3 cases (3 hips). All the mild and moderate cases were undergone insitu single screw fixation, and three severe cases were performed subtrochanteric osteotomy of femur with external fixator. All the cases were evaluated at 3 months, 6 months and every year postoperatively. Results All the cases were followed up for average 5.6 years (range, 2-12). The Harris hip score increased from mean 74.8 points preoperatively to 90.6 points postoperatively, with 10 hips excellent, 1 hip good, 1 hip fair and 0 hip poor. The excellent and good rate was 91.7% (11/12). The X-ray showed the epiphyseal closure in in-situ single screw fixation cases, and no further increase in epiphyseal-shaft angle. Partial reduction of slipped epiphysis with normal joint spaces was observed in subtrochanteric osteotomy of femur with external fixator cases. Conclusion In-situ single screw fixation provides a surgical treatment option to treat mild and moderate SCFE with satisfactory clinical outcome, and profit to the prevention further slip. Subtrochanteric osteotomy of femur with external fixator is suitable for severe SCFE with late deformity. The realignment procedure can correct deformity and postpone or avoid the occurrence of osteoarthritis.

Objective To explore the relationship between the osteonecrotic volume (lesion size), angle and the index of necrotic extent on the femoral head. Methods Fifty-one hips in 39 patients with non-traumatic avascular osteonecrosis on the femoral head were divided into 12 equal segments from the head to the neck junction (a turning point of the spherical curve of the head) with whole hip displacement, each with 30 degrees on a coronal plane of weight-bearing surface. The osteonecrotic angle of the arc of each necrotic segment from the center of the femoral head was measured at the point of one- to 12-o'clock on imaging of two dimensional reconstruction of computerized tomography (CT) scans and anteroposterior and lateral radiographs. Necrotic volume on each segment of the femoral head was calculated with fluid displacement method. The index of osteonecrotic extent on the femoral head was calculated using direct anatomical measurements. Results Osteoneerotic volume on the femoral head at the point of 12- to one-o'clock on coronal plane was (74. 5 ± 7.4)% of the sphere equivalent of the whole femoral head, which was positively correlated to its necrotic angle [ (41.9±8. 3) degrees] at the point of one-o'clock on the plane, with a coefficient of correlation of 0. 843, and that at the point of one- to two-o'clock on the plane was (73.7 ±0. 4) %, which was positively correlated to its necrotic angle [ (41.9 ± 1.8) degrees] at the point of two-o'clock, with a coefficient of correlation of 0. 543. Osteonecrotic volume on the point of 11- to 12-o'cleck was (83.6±8.6)%, and the necrotic angle at the point of 12-o'clock was (44. 9±3.9) degrees, which were positively correlated each other, with a coefficient of correlation of 0. 701 (P <0. 01 ). Osteonecrotic volume on the femoral head was positively correlated to its necrotic angle , modified index of necrotic extent, index of necrotic extent and Kerboul conjugated necrotic angle, with coefficients of correlation of 0. 798, 0. 701, 0. 377 and 0. 398 ( P < 0. 01 ), respectively, at the point of one o' clock. Conclusions Measurements of osteonecrotic volume was positively correlated to the index of necrotic extent and necrotic angle on the femoral head, respectively. Necrotic angle on the plane at 30-degree of the trochanter on the femoral head can well reflect its necrotic volume.

Aim To investigate the effect of the total flavonoids of Epimedium (TFE)on MAPK/NF-κB sig-naling pathway and the inflammatory reaction in the hippocampus of natural aging male rats.Methods The morphological changes of the hippocampus com-posed of three areas (CA1 ,CA3 and DG)were ob-served using haematoxylin-eoin (HE ) staining.The protein expression levels of senescence-associated pro-tein p21,apoptosis-related proteins Bax and Bcl-2, nuclear transcription factor-κB p65 (NF-κB p65 )and its downstream inflammatory factors TNF-α,IL-1βand COX-2,and MAPK signaling pathway-related proteins (ERK1/2,p-ERK1/2,JNK,p-JNK,p38MAPK,p-p38MAPK)in hippocampal were detected by Western blot.Results Compared with natural aging group, TFE obviously improved the morphology and structure of hippocampal neurons,and the nerve cells arranged neatly and closely. Furthermore, TFE significantly downregulated the protein expression levels of p2 1 and Bax,upregulated the protein expression levels of Bcl-2 and the ratio of Bcl-2/Bax,and reduced the expression of NF-κB p65 and of its downstream inflammatory fac-tors TNF-α, IL-1β, COX-2, and MAPK signaling pathway-related proteins (p-ERK1/2,p-JNK and p-p38 MAPK ) in hippocampus of natural aging rats. Conclusions TFE effectively protects against inflam-matory reaction in brain aging of SD male rats.The mechanism is related with inhibition of NF-κB nuclear translocation and reduction of its downstream inflamma-tory cytokines expression by inhibiting MAPK signaling pathway activation.

Objective To investigate the feasibility and accuracy of volumetric measurement of necrotic lesion using CT and MRI,and to assess the value of necrotic lesion volume in predicting collapse of the femoral head in patients with avascular necrosis of the femoral head(ANFH). Methods Comparison among CT,MRI and gross section was performed in 25 femoral heads of 18 patients who underwent total hip replacement for established ANFH.The volume of necrotic lesion was measured using fluid displacement.CT and MRI data were transferred to a computer to calculate the volume of necrotic lesion using software.One way ANOVA was used to compare the volumes of necrotic lesion measured by CT,MRI and gross section.A total of 62 patients (92 hips) who were diagnosed with ANFH but without collapse by CT were followed up 24 months.Student t-test was used to compare the ratio of the volumes of the necrotic lesion and entire femoral head in the hips with and without collapse and ROC curve analysis was carried out.Results CT and MRI coincided with gross section in the necrotic area,proliferative area and extralesional area.The volumes of the necrotic lesion measured by CT,MRI and gross section were ( 20.5 ± 5.2 ),( 21.4 ± 4.8 ),( 20.9 ± 5.2 ) cm3,respectively.There was no significant difference among the necrotic volumes measured by the three methods(F =0.185,P =0.831 ).In fifty-seven out of 92 hips,collapse of the femoral head occurred during the follow-up.The ratio of the volumes of the necrotic lesion and entire femoral head was higher in hips with collapse than in hips without collapse[ (34.5 ±9.3)% vs.(23.4 ±8.4)% ;t =5.749,P=0.000].The area under the ROC curve was 0.808. Conclusions The volume of the necrotic lesion plays an important role in the collapse of femoral head in patients with ANFH.Both CT and MRI can identify the shape and location of the necrotic lesion intuitively and stereospecifically and can determine the volume of the necrotic lesion accurately.
