ABSTRACT

Objective:To investigate the serum 25-hydroxyvitamin D [25(OH) D] levels in elderly patients with hip and vertebral compression fractures (VCF).Method:Ninety patients (58 males and 32 females) aged over 60 years with hip fracture and 120 patients (88 males and 32 females) aged over 60 years with VCF admitted in the Aviation General Hospital from January 2017 to June 2019 were enrolled. Serum 25(OH)D levels were measured.Results:Serum level of 25 (OH) D in hip fracture patients was (9.0±6.8) μg/L, the 25 (OH) D level was lower than the normal value(<19.0 μg/L)in 79 patients and<3 μg/L in 24 patients. The level of 25(OH)D in VCF patients was (16.7±10.6) μg/L, the 25 (OH) D level was<19.0 μg/L in 78 patients (65.0%) and <3 μg/L in 10 patients (8.3%). The low level of 25(OH)D was negatively correlated with age in two groups ( r=-0.367, P=0.01; r=-0.313, P=0.04). The mean level of 25 (OH) D in the hip fracture group was lower than that in the VCF group ( t=5.960, P<0.01), and the low 25(OH)D rate in the former group was significantly higher than that in the latter group (χ 2=14.14, P<0.01; χ 2=12.74, P<0.01). The 25(OH)D value of female VCF patients was (14.5±8.8) μg/L, which was significantly lower than that of male patients (22.5±12.9) μg/L ( t=3.882, P<0.01).Among hip fracture patients, the 25(OH)D level in patients with fracture history was (8.3±6.9) μg/L, which was significantly lower than that of patients without fracture history (10.8±6.9) μg/L, and the difference was statistically significamt ( t=2.123, P=0.04). The serum osteocalcin level was (20.5±19.8) μg/L in patients with fracture history, which was significantly higher than that in patients without fracture history [(10.6±5.4) μg/L, t=3.245, P<0.01]. Conclusion:Elderly patients with new hip fractures have more severely low vitamin D level than patients with new VCF, and patients with previous fracture history have lower vitamin D levels than patients without fracture history.

ABSTRACT

Objective To assess the perioperative hidden blood loss in aged patients with femoral intertrochanteric fracture.Methods Clinical data of 243 patients (111 males and 132 females) with intertrochanteric fracture admitted from 2009 September to 2015 September were retrospectively reviewed.Two hundred and seventeen patients aged 60-98 years received surgical treatment and 26 patients aged 62-91 years received conservative treatment (non-surgical group).In surgical group,17 cases were operated within 1 d after fracture,71 within 3 d,73 within 7 d,31 within 14 d,and 25 cases were operated after 14 d.Hidden blood loss was evaluated and blood routine was tested.Results The hidden blood loss was (340 ± 216) ml in non-surgical patients,(602 ± 216) ml in patients operated after 14 d,(671 ± 327) ml in patients operated 8-14,(596 ± 362) ml in patients operated 4-7 d,and (505 ± 119) ml in patients operated 2-3 d,(498 ± 244) ml in patients operated within 1 d;there was significant difference among groups (F =14.758,P =0.001).The hemoglobin level in non-surgical group was (121.8 ± 17.6) g/Lwithin 1 d after fracture,(101.1 ±23.3) g/L on 1-3 d,(91.5 ±31.9) g/L on4-7 d,(92.2 ±31.6) g/L on 8-14 d,and (108.3 ± 22.4) g/L after 14 d;there was statistically significant among groups (F =12.457,P =0.001).Conclusions Hemoglobin level in elderly patients with femoral intertrochanteric fracture is dynamically changed,and reaches the lowest point within 1-2 weeks after injury;and operation is an important factor of hidden blood loss in femoral intertrochanteric fracture patients.

ABSTRACT

Objective To investigate effects of Ginkgo biloba extract(EGb) on expression of CREB and pCREB in cortex of aging rats.Methods Male Wistar rats were divided into three groups:young control group,old control group and EGb group.Rats in EGb group were treated with intragastric administration of EGb,while rats in the other two groups were treated with distilled water.The spatial learning and memory were evaluated by Morris water maze,and the expression of CREB,pCREB were detected by western blot.Results( 1 ) Compared with young control group (9.6 ± 2.88,41.55 ± 6.30),the swimming time and times through platform in the target quardrant of rats in old control group(6.8 ± 2.49,34.92 ± 4.56) were reduced (P < 0.05 ).The times passing through the platform and the time exploring the target quadrant were more and longer in EGb group(9.4 ± 2.63,41.0 ± 6.68 ) than those in old control group(P < 0.05 ).(2)Compared with rats in young control group( 1.07 ±0.33,0.26 ± 0.04),relative contents of CREB and p-CREB proteins in cortex (0.70 ± 0.21,0.13 ± 0.05 ) weredecreased in old control group(P<0.05 ).CREB and p-CREB Levels were higher in EGb group ( 1.02 ±0.18,0.18 ±0.02)than those in old control group(P < 0.05 ).Conclusion EGb can ameliorate spatial learning and memory of rats by increasing the expression of CREB and p-CREB in cortex.

ABSTRACT

One hundred and fifty femoral head necrosis patients with intramedullary decompression received autologous stem cell transplantation. The blood was taken from unilateral or bilateral iliac, in each group the volumes of blood taken were 200, 300 or 400 ml respectively. The number of mononuclear cells was counted before and after centrifugation. The mononuclear cell count in subgroup of 200 ml,300 ml and 400 ml taken from unilateral iliac after centrifugation was (3. 11 ±1. 42) × 1010/L, (2. 62 ±1. 31 ) × 1010/L and(2. 13 ±. 91) × 1010/L. The concentration was significantly lower in subgroup of 400 ml than that of 200 ml (t=5. 118, P<0. 01). The mononuclear cells count in subgroup of 200 ml,300 ml and 400 ml taken from bilateral iliac was(4. 51 ±. 21) × 1010/L, (3. 89 ±. 06) × 1010/L and (2. 98 ±1. 39) × 1010/L, the concentration was significantly lower in subgroup of 400 ml than that of subgroup of 200 ml (t = 6. 446, P < 0. 01). Whether 200 ml or 300 ml or 400 ml blood were taken, the mononuclear cell count in blood taken from bilateral iliac after centrifugation was significantly higher than that from unilateral iliac(t = 3. 119,P < 0. 01; t = 5. 544, P < 0. 01 ;t = 2. 207 ,P < 0. 05). The results indicate that the concentration of isolated bone marrow mononuclear cells is higher from bilateral iliac than unilateral iliac. The concentration of isolated monocytes is reduced gradually with the increased blood volume.

ABSTRACT

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.

ABSTRACT

This retrospective study was to compare the clinical effects of arthroscopie drilling with arthroscopic microfracture technology on full-thickness chondral defects in 68 patients treated between March 2003 and June 2005. The patients were followed up for an average of (20 ± 5 ) months. Lysholm score and Tegner scale were used to evaluate the efficacy. For the arthrescopic drilling group (n = 15 ) and the microfracture surgery group (n =27) , total effective rates were 12/15 and 85% (23/27), respectively. Our data suggest that those two methods provide simple and effective surgical procedure for the treatment of chondral defects of the knee; the results of arthroscopic microfracture were significantly better than arthroscopic drilling.
