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.

Objective:To improve the therapeutic gain ratio from 125I seed implants by investigating the QA/QC strategies used in brachytherapy treatment of lung cancer. Methods:A total of 287 lung cancer and pulmonary metastases cases were studied. Among which, 184 are male and 103 are female with a mean age of 61.9 years. The NOA-NSCLC subgroup and pulmonary metastases were targeted on conventional CT positioning. Considering that COA-NSCL subgroup on the tumor target area is difficult to determine with CT, the coincidence circuit SPECT was used to assist in positioning. A dose-volume histogram was constructed to evaluate the quality of the TPS and optimization. Corrections on real-time positioning are necessary when using an image-guided implantation. The C-LC should be aligned with the FFB for CT-guided percutaneous puncture implantation. After implantation, dosimetry verification was con-ducted. Results:The NOA-NSCLC subgroup, comprising the risk organs such as heart, lung, and spinal column, received an average dose of 137, which was significantly lower than that of normal tissue dose tolerance. The NOA-NSCLC subgroup and lung metastases have matched peripheral dosages of 92.1 and 106.2 Gy with local-control efficiency rates of 91.97% (126/137) and 96.0% (48/50), 1-year survival rates of 91.24%and 83.4%(42/50), and 2-year survival rates of 50.36%(69/137) and 52.3%(26/50), respectively. The 35 COA-NSCL subgroup and 65 lung cancer group have local control efficiency rates of 91.43%(32/35) and 92.3%(60/65) and 1-year survival rates of 88.57%(31/35) and 80.30%(53/66), respectively. Conclusion:Proper radiation dosimetry as a QA/QC strategy was found to improve particle-implantation therapy gain and greatly reduce the risks of radiation pneumonia and pulmonary fibrosis.

Methods DHPLC and PCR direct sequence were used to detect the mutation of FGFR3 and p53 in BTCC (n=98) and normal bladder mucosa (n=10). Genomic DNA of 98 BTCC was extracted. The exon 5-8 of P53 and the exon 7, 10, 15 were amplification by PCR. The products of PCR was screened by DHPLC to detect the mutation of the production. The results of the FGFR3 and p53 mutation were analyzed by Kaplan-Meier method and no recurrence survival rate was tested by log rank test. All the analysis were aim to explore the clinical biological value of the mutation of FGFR3 and p53. Results Mutation of FGFR3 in BTCC (44. 9%) was higher than normal bladder mucosa(0, P<0.01). Mutation in T_a-T_1 was 75. 6%(33/45) ,T_2 -T_4 was 26. 6%C10/53). Mutation in G_1 was84. 6%(11/13),inG_2 was 61. 4% (27/44), in G_3 was 14. 6% (6/41), (P<0. 05). The mutation rate was lower with the higher of stage and grade. Mutation of p53 in BTCC (34. 6%) was higher than normal bladder mucosa (0%) (P<0. 01). Mutation in T_a - T_1 was 20. 0% (9/45), T_2 - T_4 was 47. 2%(25/53). Mutation in G_1 was G_1 7. 7%(1/13), in G_2 18. 2%(8/44),in G_3 58. 1%(25/41) , (P<0. 05). The mutation rate was higher in the higher stage and grade. Kaplan-Meier method results revealed that mutation of FGFR3 indicating a favorable prognosis while mutation of p53 indicating a poor prognosis. As to the analysis of genotype, the type of FGFR3mut/p53wt had a relative longer recurrent interval (P<0. 01). Conclusions Mutation of FGFR3 indicated a relative longer recurrent interval, which revealed a favorable prognosis of BTCC. Mutation of p53 indicated a relative shorter recurrent interval, which revealed a poor prognosis.
