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 This study explored the expression of polyclonal protein SUZ12 in patients with intrahepatic cholangiocarcinoma(ICC),and its role in predicting the survival and treatment of ICC patients.Methods The expression of SUZ12 and p16INK4a was detected by immunohistochemical assay in 207 liver tissue samples including ICC patients,BilIN-1,-2,-3 and non-tumor-like cholangiocarcinoma.The expression of these proteins was assessed to be related to the pathological characteristics of the ICC patients receiving chemotherapy and the outcome of survival as well as the subsequent chemotherapy response.Results The expression level of SUZ12 was gradually increased from non-neoplastic bile duct tissue to BilIN-1,-2,-3 and ICC.The expression of p16INK4a protein was expressed in non-neoplastic-like cholangiocarcinoma,but it decreased gradually in BilIN-1,-2,-3 and ICC tissues.SUZ12 expression was associated with undifferentiated ICC,lymph node metastasis and advanced cancer.Kaplan-Meier curve analysis showed that ICC patients with high expression of SUZ12 had a significant reduction in overall survival and disease-free survival in comparison with ICC patients with the low expression of SUZ12.SUZ12 expression was significantly associated with overall survival of patients receiving adjuvant gemcitabine-based chemotherapy(AGC).Conclusion SUZ12 expression is able to predict the overall survival and disease-free survival of ICC patients with adjuvant gemcitabine-based chemotherapy.
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.

The IDH1 mutation rate in patients with WHO grade II astrocytoma was higher than that in patients with WHO grade III tumor (P < 0.05). The age at onset was an independent factor affecting the expression of mutant IDH1. After radiotherapy, patients with IDH1 mutation+/MGMT- tumor carried a longer overall survival time than patients with IDH1 mutation-/MGMT+ tumor (P < 0.05).</p><p><b>CONCLUSIONS</b>There is a correlation between IDH1 mutation and MGMT expression in WHO grade II to III astrocytoma. Age at onset is an independent factor affecting the expression of mutant IDH1. Tumors with IDH1+/MGMT- pattern show better response to radiotherapy than tumors with IDH1-/MGMT+ pattern. Detection of IDH1 mutation and MGMT protein expression can provide some guidance in choice of treatment modalities in patients with astrocytoma.</p>

BACKGROUND:Intermittent negative pressure has been proven to promote the repairing of soft tissue and bone healing, but the effect of negative pressure on the tendon-bone healing after anterior cruciate ligament reconstruction has not been reported. OBJECTIVE:To research the effect of intermittent negative pressure on tendon-bone healing after anterior cruciate ligament reconstruction and on the biomechanics of tendon grafts. METHODS:A total of 24 New Zealand white rabbits were randomly selected to establish the models of anterior cruciate ligament reconstruction of autogenous semitendinosus. The hind leg of one side was selected randomly as the negative pressure group, and the joint of the negative pressure side was connected with the micro-negative pressure aspirator through drainage tube and maintained a low-intensity and intermittent negative pressure;the contralateral hind leg was as the control and connected with ordinary drainage tube. Drainage tubes of both sides were removed at the same time after 5 days. At 6 weeks after modeling, the joint fluid was drawn to detect the expression levels of interleukin-1β;femur-ligament-tibia complex was used for tension measurement of tendon graft, and histological observation of tendon-bone interface. RESULTS AND CONCLUSION:One rabbit had joint infection, and final y 23 rabbits were included in the study. Tension measurement results showed that maximum load for breakage in negative group pressure was significantly greater than that in the control group (P<0.05). Histological observation found that the number of osteoblasts in the negative pressure group was significantly more than that in the control group, and the difference was statistical y significant (P<0.01). Detection of synovial fluid showed that iterleukin-1βcontent in synovial fluid of the negative pressure group was lower than that in the control group, and the difference was statistical y significant (P<0.01). Intermittent negative pressure may play an active role in tendon-bone healing and modeling of tendon graft after anterior cruciate ligament reconstruction.
