Objective: To explore the safety and preliminary effectiveness of transintervertebral release, bone impaction grafting, and posterior column compressed-closing in the treatment of osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis. Methods: The clinical data of 21 elderly patients with osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis were retrospectively analyzed between March 2016 and November 2017. There were 1 male and 20 females, aged 55-75 years, with an average of 64.8 years. The disease duration was 8-24 months, with an average of 13.1 months. The bone density T value ranged from -3.4 to -2.1, with an average of -2.3. Lesion segments: T 11 in 2 cases, T 12 in 6 cases, L 1 in 8 cases, L 2 in 1 case, T 11, 12 in 1 case, T 12, L 1 in 2 cases, and T 12, L 2 in 1 case. Preoperative neurological function was classified according to the American Spinal Injury Association (ASIA): 5 cases of grade D and 16 cases of grade E. All patients underwent transintervertebral release, bone impaction grafting, and posterior column compressed-closing. The effectiveness was evaluated by visual analogue scale (VAS) score and Oswestry dysfunction index (ODI) score before operation, at 3 months after operation, and at last follow-up. The neurological function was assessed by ASIA at last follow-up. Local kyphosis Cobb angle (LKCA), thoracic kyphosis (TK), lumbar lordosis (LL), and sagittal vertebral axis (SVA) were measured on the X-ray films of the full-length lateral spine of the patient before operation, at 1 week after operation, and at last follow-up. Results: No complication such as fracture of internal fixator or nerve injury occurred. LKCA, TK, and SVA were significantly improved at 1 week after operation and at last follow-up ( P<0.05). There was no significant difference between at 1 week after operation and at last follow-up ( P>0.05). There was no significant difference in LL before and after operation ( F=3.013, P=0.057). The VAS and ODI scores were significantly improved at 3 months after operation and at last follow-up, and further improved at last follow-up when compared with the scores at 3 months after operation, showing significant differences between time points ( P<0.05). Five patients with ASIA grade D neurological function recovered to grade E at 6 months after operation. Conclusion: Transintervertebral release, bone impaction grafting, and posterior column compressed-closing for treating osteoporotic vertebral fracture combined with moderate to severe spinal kyphosis has definite effectiveness, strong orthopaedic ability, and minimal trauma, which can effectively restore the sagittal balance of the spine, alleviate pain, and improve the patients' quality of life.

Objective To study the correlation of HLA-G levels with acute rejection and CMV active infection post-kidney transplantation.Methods A total of 132 initial kidney transplantation recipients were divided into kidney function stable group (F),acute rejection group (AR),CMV group according to whether they had active CMV infection and acute rejection.Forty-one healthy donors served as control group (H).HLA-G levels and mRNA expression were analyzed by using flow cytometry,ELISA,RT-PCR and Western blotting.Immunohistochemical staining was used to detect the HLA-G expression in kidney biopsies.Results The expression levels of mHLA-G1 were low in all 4 groups pre-transplantation.Only CMV group had significantly more CD14+ mHLA-G1+ cells post-transplantation (P＜0.05).sHLA-G5 levels were higher in F group than in H group (P＜0.05),but there was no significant difference among other groups pre-transplantation (P＞0.05).sHLA-G5 levels were increased significantly in CMV group as compared with F group (P＜0.05),and those in F group were higher than in H and AR groups (P＜0.05).Renal tissue biopsies from 21 renal transplantation recipients with AR indicated that HLA-G5 was expressed negatively in 17 patients,positively in 3 patients and 1 weakly positively.HLA-G was positive in the kidney tissue of 9 patients out of 9 patients with active CMV infection.In total 132 recipients,AR incidence was significantly lower in CMV ( + ) group (7.1 ％,2/28) than that in CMV ( - ) group (24.0 ％,25/104).Conclusion The sHLA-G5 may contribute to predict AR and CMV active infection; AR and CMV active infection may be correlation with immune balance in kidney transplantation recipients.

Objective To measure the cytokines levels in peripheral blood from kidney transplantation recipients by using cytometric bead array and to analyze their change and the clinical significance in pre- and post- kidney transplantation, inducting with basiliximab and graft rejection. Methods A total of 72 renal transplantation recipients were divided into two groups, kidney function stable group(n =53) and acute rejection group (n = 19). And they were also grouped by induction with basiliximab or not,32 in basiliximab group and 40 in without basilixmab group. The levels of IFN-γ, TNF-α, IL-10, IL-5,IL-4, IL-2 were measured by cytometric bead array in peripheral blood of 72 kidney transplantation recipients and 30 healthy donors at differential time. The data was analyzed according to the following grouping:donors and recipients, kidney function stable group and acute rejection group post transplantation and with or without basiliximab group. Results The levels of TNF-α, IL-10, IL-5, IL-4, IL-2 in recipients before transplantation were ( 1.65 ±0. 10) ,(2. 55 ±0. 19) ,( 1.88 ±0. 14) ,(1.85 ±0. 12) ,(2. 12 ±0. 09) ng/L,respectively. While they were (3.04 ±0. 17), (3.33 ±0. 26), (4.03 ±0.25), (2.73 ±0. 16), (4.03 ±0. 26) ng/L respectively in healthy donors. There was statistical significance between the two groups ( t =6. 890, 2. 375, 7. 851,3.955,7.153, P<0. 01, <0. 05, <0.01, <0.01, <0.01). While the level of IFN-γ in recipients before transplantation was (2. 50 ±0. 18) ng/L,compared with (3. 00 ±0. 24) ng/L in healthy donors. There was no statistical significance between the two groups( t = 1. 625, P > 0. 05 ). The levels of IFN-γ and IL-10 in kidney function stable group were (2. 71 ± 0. 11 ) ng/L and (3.91 ± 0. 52) ng/L,while they were ( 3.30 ± 0. 36 ) ng/L and ( 12. 01 ± 5.35 ) ng/L in acute rejection group. There were statistical dirrerences between the two groups ( t = 5. 061, 11. 465, P < 0. 01, < 0. 05 ). Before induction with basiliximab, the levels of IFN-γ, TNF-α, IL-10 in recipients were (2.90 ±0. 21 ), ( 1.67 ±0. 12),(2. 45 ± 0. 16) ng/L respectively. But they were ( 2. 78 ± 0. 17 ), ( 1.58 ± 0. 07 ), ( 2. 77 ± 0. 24 ) ng/L respectively after induction with basiliximab, which showed significantly different ( t = 5. 605, 6.011,4. 126, P <0. 01, <0. 01, <0. 05). Four weeks after kidney transplantation in recipients with basiliximab,the levels of IFN-γ, IL-10, IL-4 were (2. 90 ± 0. 31 ), (9. 08 ± 0. 16), (2. 73 ± 0. 11 ) ng/L. While they were (3.28 ±0. 11 ), (4. 17 ±0. 21 ), (2. 11 ±0. 20) ng/L respectively in recipients without basiliximab induction, which were significantly different from those with basiliximab induction (t = 4. 268,4. 263,3.762, P <0. 01, <0. 01, < 0. 05 ). Conclusions Six kinds of cytokines can be measured by cytometric bead array simultaneously and accurately. The data suggests that the detection of multiple cytokines in kidney transplantation recipients by cytometric bead array can provide more guidance for clinical diagnosis and therapy.
