Objective To explore the effect of living mode on quality of life and life satisfaction of patients with spinal cord injury who survived Tangshan earthquake. Methods From February to May, 2016, 76 patients with spinal cord injury survived the earthquake were in-vestigated, among whom 38 patients lived in the nursing home or rehabilitation village and the other 38 patients discretely lived at home. Their quality of life and life satisfaction were assessed with WHO Quality of Life-BREF (WHOQOL-BREF) and Life Satisfaction Assess-ment respectively. Results The scores of physical, psychological, social adaptation and environment field in WHOQOL-BREF were signifi-cantly higher in the concentrated living group than in the scattered living group (t>8.97, P<0.001), as well as the life satisfaction (t=6.55, P<0.001). Conclusion The concentrated living mode could improve the quality of life and life satisfaction of the patients with spinal cord inju-ry survived Tangshan earthquake.

Objective To survey the survival status, functional status, marital status and the present situation of the survival patients with spinal cord injury 40 years after Tangshan earthquake. Methods From February to May, 2016, a total of 216 patients with spinal cord injury were surveyed with questionnaire, in which 139 cases lived centralized and 77 cases lived scattered. The questionnaire was self-designed and included eleven items and 51 questions, which related to ability of daily life, marital status, employment status and socioeconomic status and so on. Results A total of 960 (25.15%) patients with spinal cord injury survived 40 years after Tangshan earthquake. In 216 surveyed pa-tients, the employment rate was 9.3%, the married rate was 53.2%, and 44.9%earned less than 500 yuan every month. The incidence was 25.9%for pressure score, 50.50%for neuralgia (severe pain accounted for 23.51%), and 19.40%for urinary tract stones. 56%of patients could take their own basic self-care. Conclusion There were many problems such as high complication rate, low employment rate and poor economic condition in the spinal cord injury group 40 years after Tangshan earthquake.

Objective:To investigate the efficiency and safety of traditional growing rod in the treatment of early onset dystrophic scoliosis secondary to type 1 neurofibromatosis (NF1-DS) with intraspinal rib head in children.Methods:From September 2006 to May 2020, this study recruited 20 children with intraspinal rib head with early onset NF1-DS who had received traditional growing rods. There were 13 boys and 7 girls and the age of the initial operation was 7.0±1.6 years (range, 4.1-9.8 years). There were 7 cases of simple left chest bend, 9 cases of simple right chest bend, and 4 cases of double chest bend; 13 patients had varying degrees of kyphosis deformity. Two children had neurological symptoms before surgery, American Spinal Injury Association Impairment Scale (AIS) were grade D. The proportion of the intraspinal rib head (IRP), the Cobb angle of the main chest bend, apical vertebra rotation (AVR), apical vertebral translation (AVT), trunk shift (TS) and sagittal TK, lumbar lordosis (LL), sagittal balance and T 1-S 1 height were measured before and after first time internal fixation and at last follow-up, and the complications were also evaluated. Results:All 20 patients were followed up and the average follow-up time was 41.6±23.8 months (range, 24-99 months). A total of 85 operations was conducted including 63 protrude operations. After operation, the IRP was significantly lower than that before operation (preoperative 33.1%±17.5% vs. postoperative 22.2%±11.3%, P<0.001) and no significant correction loss was found at last follow-up 23.7%±12.4% ( P>0.05). The mean Cobb angle decreased from 75.9°±26.7° preoperatively to 45.0°±18.5° postoperatively ( P<0.001) and there was still significant improvement at the last follow-up (41.0°±17.2°) compared with postoperatively ( P<0.05). The AVR was significantly reduced after surgery compared with preoperatively (33.0°±10.1° vs. 39.3°±13.3°, P<0.001), and the last follow-up (40.1°±11.4°) was significantly improved compared with postoperative ( P=0.005). The T 1-S 1 height increased from 259.8±70.7 mm preoperatively to 296.9±78.4 mm postoperatively ( P=0.001), and at the last follow-up 296.9±78.4 mm was still significantly higher than after operation ( P<0.001), with an average annual increase of 12.4±3.2 mm. Significant correction of AVT, TK, LL and sagittal balance were noted after initial surgery ( P<0.05), and no significant correction loss was found at last follow-up ( P>0.05). There were 10 complications in 7 cases. There were 5 complications of pedicle screw loosening, 1 complication of bolt droping, 2 complications of broken rod, 1 complication of distal junctional kyphosis and 1 complication of adding-on phenomenon. 2 cases with nerve injury were recover after operation (AIS grading E). None of the children had new neurological complications during growth rod insertion and multiple stretching during follow-up. Conclusion:For children with early onset NF1-DS with intraspinal rib head, if the preoperative AIS grade is D or E, traditional growing rod technique is relatively safe and effective and can make the intraspinal rib head remove from the spinal canal partly.

Objective To assess the potential role of disulfidptosis-related genes (DRGs) in pan-cancer on prognosis and immunity on the basis of bioinformatics approaches. Methods Pan-cancer RNA-seq data, mutation profiles, clinical information, TMB, MSI, stemness scores, and tumor and immune microenvironment data contained in TCGA and various open-source online databases, and multi-group R-language algorithms were used for comprehensive analysis. The expression levels of DRGs at the cellular level were experimentally validated using qPCR. Results LRPPRC, NCKAP1, NDUFS1, and NUBPL had a better prognosis in renal clear cell carcinoma (P<0.001), whereas SLC7A11, NCKAP1, and SLC3A2 had a worse prognosis in hepatocellular carcinoma (P<0.001). TME analysis showed that LRPPRC was negatively correlated with immune cells, stromal cells, and estimated scores in all tumor types. TMB analysis revealed the potential research value of DRGs for PD-1/PD-L1 therapy in pan-cancer. Drug sensitivity analysis showed that SLC7A11 (r=0.454), SLC3A2 (r=0.366), and NCKAP1 (r=0.455) were significantly associated with Kahalide F (P<0.01). Experimental validation demonstrated the overall higher expression levels of GYS1 and NCKAP1 than normal cells in lung adenocarcinoma, colon adenocarcinoma, esophageal squamous carcinoma, and hepatocellular carcinoma (P<0.05). Conclusion Pan-cancer analysis of DRGs indicates that DRGs may serve as important biomarkers for the diagnosis and prognosis of renal clear-cell carcinoma, lung adenocarcinoma, and hepatocellular carcinoma.
