ABSTRACT
【Objective】 Until now, most clinical and basic studies on Kashin-Beck disease (KBD) have focused on the visible deformed extremities, and there is a lack of reports concerning their spinal features, especially for the atlantoaxial joint. The purpose of this study was to determine the prevalence and radiographic features of atlantoaxial dislocation (AAD) in KBD in adult patients. 【Methods】 The prevalence and radiographic features of AAD were determined by the basic information collected, clinical symptoms, and lateral and dynamic plain radiography in 111 KBD patient and 120 non-KBD participants. In the KBD group, AAD and non-AAD patients were compared in age, gender, height, weight, BMI, smoking history, chronic history, disease duration and grade of disease so as to identify the related factors of the occurrence of AAD. 【Results】 Symptoms at the neck or neurological manifestations were present in 17.5% (21/120) in the non-KBD population and 39.6% (44/111) patients with KBD. AAD case was not detected in the non-KBD population, while in 16.2% (18/111) of KBD patients in the endemic area. The prevalence was higher in the KBD patients than in the non-KBD population, and there was a significant difference in the detection rate of AAD between the two groups (χ2=21.10, P<0.001). Plain radiography demonstrated that there were 10 (55.6%) cases with separation of the odontoid process and the other 8 (44.4%) cases with hypoplasia of odontoid process. Anterior AAD was noted in 12 (66.7%) patients and posterior AAD in 6 (33.3%) cases based on the displacement direction, while 16 (88.9%) cases were reducible and 2 (11.1%) cases were irreducible on the basis of the reducibility. Comparing the 93 patients with non-AAD KBD patients and 18 patients with AAD patients, there was no significant difference in age, sex, BMI, history of medical disease or smoking (all P>0.05). There were significant differences in height, weight, disease duration and grade of disease between AAD and non-AAD patients (all P<0.05). 【Conclusion】 KBD can cause the occurrence of atlantoaxial dislocation by inducing separation or hypoplasia of the odontoid process. This research may provide clinical evidence for screening, earlier prevention and treatment of atlantoaxial dislocation in adult KBD patients.
ABSTRACT
Objective To evaluate the quality of life of patients with Kaschin-Beck disease (KBD)receiving total knee arthroplasty (TKA) before and after the operation.Methods Clinical efficacy of 25 patients with KBD who underwent TKA in Department of Orthopaedics,Shaanxi Provincial People's Hospital from January 2015 to January 2017 was prospectively analyzed.A questionnaire survey on KBD quality of life (KBDQOL)was carried out to evaluate the quality of life of the patients before,6 months and 1 year after the surgery.Results The scores of physical function,activity limit,social support,mental status and total health scores of KBDQOL in 6 months after the surgery (30.60 ± 3.73,23.24 ± 2.03,15.16 ± 1.62,18.92 ± 2.89,12.80 ± 2.57) and 1 year after the surgery (32.00 ± 3.19,23.76 ± 1.59,15.60 ± 1.29,20.16 ± 2.67,17.28 ± 3.88) were significantly higher than those of before the surgery (18.84 ± 4.94,21.04 ± 2.72,12.80 ± 2.06,13.68 ± 3.42,7.92 ± 1.93,P ＜ 0.05).However,there was no significant difference in economic scores before,6 months and 1 year after the surgery (10.68 ± 2.98,10.60 ± 2.78,10.48 ± 2.80,P ＞ 0.05).Conclusions The quality of life after TKA in patients with KBD severe knee osteoarthritis is significantly better than that before the surgery.The KBDQOL questionnaire is an appropriate tool for evaluating the quality of life in KBD patients.

ABSTRACT
Objective To detect the expression of IL-17 in renal transplant recipients by Luminex and evaluate the relationship between the level of serum IL 17 and early acute renal allograft rejection.Methods 38 kidney transplant recipients and healthy controls (HC,healthy volunteers,n =20) were selected in this study from January 2009 to October 2011.All patients were divided into two groups according to their allograft outcome as acute rejection group (ARG,n-18) and non-rejection group (NRG,n=20).The expression of serum IL-17 was detected by Luminex technique in two groups of kidney transplant recipients and HC.To evaluate the correlation between the level of serum IL-17 and early acute renal allograft rejection.Results The mean level of IL-17 in all renal transplant recipients 1.3 ± 1.9 pg/ml at the pre-transplantation was significantly lower than that in HC (6.9± 8.5 pg/ml,t=3.968,P＜0.001).The results highlighted that the level of serum IL-17 in ARG 3.4±5.8 pg/ml was significantly higher than that in NRG (0.5±0.4 pg/ml) on the 7th days post Kidney transplantation (post KTx,t=2.242,P =0.031).Kaplan-Meier survival analysis showed that the probability of rejectionfree survival in the higher levels group of IL-17 on the 7th days post-KTx was significant lower than that in the lower levels group (P＜0.001).The results of receiver operating characteristic curve showed that the sensitivity and specificity of the combined IL-17 to predict acute rejection were 66.67％ and 100％,respectively.Conclusion The serum IL-17 levels in renal transplant recipients on the 4th and 7th post-KTx days can predict early renal transplant rejection.
ABSTRACT
Objective To evaluate the clinical effects of total knee arthroplasty (TKA) in treatment of severe adults Kashin-Beck disease (KBD). Methods Sixteen cases of KBD patients underwent TKA in Shaanxi Provincial People's Hospital, including 2 males (2 knees) and 14 females (17 knees), aged 41 to 56 years, mean (56.38 ± 6.40) years, left knee in 8 cases and right knee in 11 cases, knee varus in 15 cases and valgus knees in 4 cases. Visual Analogue Scale/Score (VAS), Hospital for Special Surgery (HSS) scores, knee range of motion, varus deformity and postoperative complications were observed before and after TKA. Results In this group of TKA patients, the levels of VAS scores in pre-total knee arthroplasty (pre-TKA), 2 weeks post-total knee arthroplasty (post-TKA), 3 months post-TKA, and at the end of the follow-up were 7.51 ± 1.00, 3.56 ± 1.29, 1.83 ± 1.40 and 1.10 ± 0.87, respectively. The level of VAS scores in 2 weeks post-TKA was significantly lower than that in pre-TKA (P<0.01), and the VAS levels were continued to decrease in post-TKA (all P< 0.01). Total HSS score at the end of the follow-up post-TKA was 78.60 ± 5.30, which was significantly higher than that in pre-TKA (43.59 ± 10.08, t=19.21, P< 0.01). At the end of the follow-up post-TKA, in addition to the muscle strength, the levels of pain, knee function, activity, flexion deformity and stability (25.94 ± 4.17, 15.88 ± 3.70, 14.09 ± 1.03, 6.79 ± 2.25, 8.58 ± 1.30) were significantly higher than those in pre-TKA (11.56 ± 5.39, 7.56 ± 1.75, 9.86 ± 3.85, 3.05 ± 3.22, 5.00 ± 3.07, t= 16.00, 8.32, 6.43, 7.07, 6.95, all P< 0.01). At the end of follow-up post-TKA, the knee degree of extension [(3.05 ± 2.71)°] was significantly lower than that in pre-TKA [(15.11 ± 11.30)°, t= -5.40, P< 0.01], the knee degree of flexion [(115.79 ± 9.65)°] was significantly higher than that in pre-TKA [(93.95 ± 22.40)°, t=6.02, P< 0.01), the degree of varus [(2.40 ± 2.40)° ] and valgus [(3.75 ± 2.50)° ] deformity was significantly lower than those in pre-TKA [(11.33 ± 10.43)°, (18.00 ± 5.72)°, t = - 4.15, - 3.61, all P< 0.05]. One patient was diagnosed as knee tuberculosis in 6 months post-TKA. There was no complication in this group of patients. Conclusion The TKA in severe adults knee of KBD can significantly reduce knee pain, improve knee function, correct joint deformities and improve quality of life in patients, and shows good clinical results.
ABSTRACT
Objective To observe the clinical effect and safety of percutaneous kyphoplasty (PKP) on osteoporosis vertebral compres-sion fractures (OVCF) in elderly. Methods From January, 2014 to May, 2015, 88 patients with OVCF treated with PKP were retrospective studied. Visual Analogue Scale (VAS) and Oswestry Dysfunction Index (ODI) were used to evaluate the pain and quality of life, and the ky-photic angle (Cobb's angle) and anterior vertebral body height were recorded before operation, one week after operation and the last fol-low-up. The cement leakage and its effect on nerve function were recorded. Results Bone cement leakage was found in eleven patients, in which two in pedicle, three in venous leakage, three in intervertebral disc and three in vertebral posterior. Nerve root symptoms appeared in one patient, who was treated with decompression. The scores of VAS and ODI, and the Cobb's angel were significantly lower (t>29.518, P35.173, P<0.001) one week after operation and the last follow-up than be-fore operation. Conclusion PKP is safe and effective for OVCF in elderly. It can efficiently reduce the pain, correct kyphotic deformity and improve the quality of life.
ABSTRACT
Objective To study the expression of immunoglobulin-like transcripts 3 (ⅡT3) and ILT4 in peripheral blood dendritic cells (DC) of kidney transplantation recipients and to analyze its significance in immunity hyporesponsiveness of transplantation. Methods Twenty kidney allograft recipients who were survived more than five years were recruited to two groups: renal function stable groups, chronic rejection groups, and 10 healthy volunteers served as a control group. The peripheral blood mononuclear cells (PBMC) were stimulated with granulocyte-macrophage colony stimulating factor (GM-CSF) and interleukin 4 (IL-4) and immature DC were obtained. The expression of ILT3 and ILT4 was detected by using flow cytometry. The level of HLA-G5 in serum was determined by using enzyme linked immunosorbent assay. Results ILT3 expression in renal function stable group was increased and decreased in chronic rejection groups as compared with control group (P＜0.05),but ILT4 expression had no significant difference among all groups. HLA-G5 in serum was significantly increased in renal function stable group as compared with other groups. Conclusion Expression of ILT3 and HLA-G was increased in the kidney transplantation recipients with stable renal function and long-term survival, suggesting that they may play an important role in inducing and maintaining periphery immune tolerance.
ABSTRACT
Objective To investigate the effect of prostaglandin E: (PGE1) on recovery of early renal graft functions after transplantation. Methods One hundred and seven patients after renal transplantation were allocated in the treated group, and treated by conventional treatment with injection of 10 μg prostaglandin E1 additionally twice a day for 14 days. And eighty-eight patients who received conventional treatment alone after renal transplantation at the corresponding period were allocated in the control group. Indexes of the two groups, including incidence of delayed graft function and acute rejection reaction, volume of urine, serum certaintie (SCr), endogenous certainties clearance rate (CCr), the blood flow resistance in graft as well as blood viscosity (BV), and platelet aggregation rate (PAR), were determined. Results The urinary volume and endogenous certainties clearance rate of the treated group were significantly higher, but the level of SCr, incidence of renal function recovery retardation, BV, PAR and blood flow resistance in graft were significantly lower than these of the control group (P<0.05). The difference of incidence of acute rejection reaction between the two groups was insignificant (P>0.05). Conclusion Prostaglandin E1 can improve blood microcirculation and decrease the incidence of renal function recovery retardation. These effects are helpful for recovery of renal function after renal transplantation.
