Objective To detect the DMD gene mutation sites and the regions of breakpoints in Duchenne/Becker muscular dystrophy (DMD/BMD) patients in northern China. Methods Multiplex amplifiable probe hybridization (MLPA) was used to detect the mutation in 59 cases (51 cases with DMD and 8 with BMD) from northern China and dystrophin gene mutations in their parents. Results From northern China and dystrophin gene mutations 59 families found gene deletions in 33 cases of 59 DMD/BMD patients (55.9%), duplications in 6 cases (10. 2%) and point mutation in one case (1.7%). Intron 44 was most frequently affected (n = 13, 33.3%), followed by intron 50 (n = 11, 28.2%) and intron 45 (n=8, 20.5%). The novel mutations were identified, in two patients including two independent duplications carried by patient D1 149 and a point mutation [5208del(A)] carried by patient D1 65, which were not included in Leiden database. In addition, an exon 22 deletion was found in one patient, which was the first reported case in Chinese patients. Conclusions Deletions are mostly located in the hotspot between exon 45 and 50. Duplications mostly occurred in the 5' end of the gene. Intron 44 is the most frequently affected breakpoint in northern Chinese population.

Objective:To investigate specificity of neurovascular compression in patients with primary trigeminal neuralgia (PTN) by three-dimension reconstruction and computational fluid dynamics.Methods:Clinical characteristics and preoperative magnetic resonance imaging (MRI) data of 20 patients with both PTN and single artery compression (PTN group) and 10 patients without PTN but having neurovascular contact in MRI images (control group) in the Second Affiliated Hospital of Zhengzhou University from January 2018 to December 2019 were collected and analyzed. After three-dimension reconstruction of the MRI images, curvature of the arterial loop, angle between the plane of arterial loop and the trigeminal nerve and location of the compression were observed. Then bidirectional structure-fluid coupling based on the optimized stereolithography models of arterial loop and nerve were processed by ANSYS 19.2 software. In the location of the compression of contact, equivalent stress (ES) of arterial loop on the nerve, shearing stress (SS) of the blood flow and local deformation of the nerve were iteratively computed. All parameters were analyzed and compared between the PTN group and the control group, and the correlation analysis was proceeded between the anatomical parameters and hemodynamical parameters.Results:The curvature of arterial loop [0.21(0.12) mm -1vs 0.13(0.07) mm -1, U=34.00, P<0.05], the angle between vascular loop and nerve [69.70(30.67)° vs 43.40(37.21)°, U=38.00, P<0.05] in the PTN group were significantly greater than those in the control group, and the location of compression was significantly closer to the root of nerve in the PTN group [PTN group: (4.23±1.29) mm vs control group: (5.54±1.85) mm, t=-2.26, P<0.05]. The average SS [15 952.48(5 365.56) Pa vs 12 501.97(6 355.26) Pa, U=53.00, P<0.05], ES [24 965.65(7 693.22) Pa vs 14 992.99(9 824.08) Pa, U=32.00, P<0.05] in the PTN group were significantly greater than those in the control group. The curvature of arterial loop was positively correlated with the SS ( r=0.931, P<0.05) and ES ( r=0.962, P<0.05), and the latter two ( r=0.787, P<0.05; r=0.853, P<0.05) were positively correlated with the local neural deformation. Conclusions:In patients with PTN, offending artery compresses the root of nerve by greater arterial curvature and angle between the arterial loop and nerve. These anatomical differences will cause significantly greater SS, ES and local neural deformation.

Objective:To investigate the effect of thoracolumbar osteoporotic vertebral compression fracture (OVCF) combined with lumbar degenerative spondylolisthesis (LDS) on spinopelvic sagittal parameters in the elderly.Methods:A case-control study was conducted to analyze the clinical data of 77 patients with thoracolumbar OVCF admitted to Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine from December 2016 to December 2021. There were 16 males and 61 females with the age of 61-92 years [(73.9±8.4)years]. All patients had single-level thoracolumbar fractures (T 11-L 2). Simple thoracolumbar OVCF was found in 49 patients (OVCF group) and thoracolumbar OVCF combined with LDS in 28 (OVCF+LDS group). The pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis (LL), thoracic kyphosis (TK), thoracolumbar kyphosis (TLK), sagittal vertical axis (SVA) and Roussouly types were detected and compared between the two groups before operation. Results:There was no significant difference in PT and SVA between the two groups (all P>0.05). The PI, SS, LL, TK and TLK in OVCF+LDS group were (55.8±11.0)°, (34.1±10.9)°, (45.7±9.1)°, (35.7±6.1)° and (24.8±5.2)°, significantly larger than (47.9±8.8)°, (27.0±9.4)°, (33.1±7.9)°, (29.5±6.2)° and (18.4±5.5)° in OVCF group (all P<0.01). Roussouly types I-IV counted 22, 16, 5 and 6 patients in OVCF group, compared to 8, 5, 6 and 9 patients in OVCF+LDS group ( P<0.05). Conclusions:Elderly patients with thoracolumbar OVCF combined with LDS can significantly alter spinopelvic sagittal parameters, and LDS may aggravate the thoracolumbar kyphosis of OVCF. To avoid sagittal imbalance, surgery should be performed as soon as possible.
