Objective To evaluate the safety and effectiveness of anterior cervical discectomy and fusion (ACDF) by using zero-profile anchored cage (ZAC) in treatment of consecutive three-level cervical spondylosis, by comparing with plate-cage construct (PCC). Methods A clinical data of 65 patients with cervical spondylosis admitted between January 2020 and December 2022 and met the selection criteria was retrospectively analyzed. During consecutive three-level ACDF, 35 patients were fixed with ZAC (ZAC group) and 30 patients with PCC (PCC group). There was no significant difference in baseline data between the two groups (P>0.05), including gender, age, body mass index, surgical segment, preoperative Japanese Orthopaedic Association (JOA) score, Neck Disability Index (NDI), visual analogue scale (VAS) score, prevertebral soft tissue thickness (PSTT), cervical lordosis, and surgical segmental angle. The operation time, intraoperative blood loss, hospital stay, clinical indicators (JOA score, NDI, VAS score), and radiological indicators (cervical lordosis, surgical segmental angle, implant subsidence, surgical segment fusion, and adjacent segment degeneration), and the postoperative complications [swelling of the neck (PSTT), dysphagia] were recorded and compared between the two groups. Results Patients in both groups were followed up 24-39 months. There was no significant difference in follow-up duration between the two groups (P>0.05). The operation time and intraoperative blood loss were lower in ZAC group than in PCC group, and the length of hospital stay was longer, but there was no significant difference (P>0.05). At each time point after operation, both groups showed significant improvements in JOA score, VAS score, and NDI compared with preoperative scores (P<0.05), but there was no significant difference between the two groups at each time point after operation (P>0.05). Both groups showed an increase in PSTT at 3 days and 3, 6 months after operation compared to preoperative levels (P<0.05), but returned to preoperative levels at last follow-up (P>0.05). The PSTT at 3 days and 3 months after operation were significantly lower in ZAC group than in PCC group (P<0.05), and there was no significant difference between the two groups at 6 months and at last follow-up (P>0.05). The incidences of dysphagia at 3 days and 3 months were significantly lower in ZAC group than in PCC group (P<0.05), while no significant difference was observed at 6 months and last follow-up between the two groups (P>0.05). There was no postoperative complication in both groups including hoarseness, esophageal injury, cough, or hematoma. Both groups showed improvement in cervical lordosis and surgical segmental angle compared to preoperative levels, with a trend of loss during follow-up. The cervical lordosis loss and surgical segmental angle loss were significantly more in the ZAC group than in PCC group (P<0.05). The incidence of implante subsidence was significantly higher in ZAC group than in PCC group (P<0.05). There was no significant difference between the ZAC group and PCC group in the incidences of surgical segment fusion and adjacent segment degeneration (P>0.05). ConclusionIn consecutive three-level ACDF, both ZAC and PCC can achieve satisfactory effectiveness. The former can reduce the incidence of postoperative dysphagia, while the latter can better maintain cervical curvature and reduce the incidence of implant subsidence.
ObjectiveTo detect the differentially expressed circular RNA (circRNA) in rotator cuff tendinopathy and analyze the potential molecular mechanism of these parental genes.MethodsTen supraspinatus tendons donated from patients who underwent tendon repair surgery between June 2018 and June 2019 were used for RNA-sequence. All rotator cuff tendinopathy and normal tendon samples were confirmed by MRI, histological staining, and observation by arthroscopy. All pathological tendons were matched with tendon samples for patients’ age, gender, body mass index, and Bonar score. The bioinformatic analysis was performed based on the differentially expressed circRNA and their parental genes, including gene ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), and competing endogenous RNA (ceRNA) network construction.ResultsThere were 94 differentially expressed circRNAs, including 31 up-regulated and 63 down-regulated, detected between the rotator cuff tendinopathy and normal tendon samples with |log2 fold change (FC)| >2, P<0.05. GO analysis showed that the genes were mostly enriched in response to cyclic adenosine monophosphate (cAMP). KEGG pathway analysis showed that the most genes were enriched in extracellular matrix-receptor interaction, protein digestion and absorption, cell cycle, and nuclear factor κB signaling pathway. ceRNA networks showed the interactions among circRNAs, mRNAs, and miRNAs. And circRNA.8951-has-miR-6089-DNMT3B was the most sum max energy.ConclusionThis bioinformatic study reveals several potential therapeutic targets for rotator cuff tendinopathy, which paves the way to better treatment and prevention of this disorder.
ObjectiveTo compare the effectiveness between anterior cervical Zero-profile interbody fusion device (Zero-P) and anterior cervical plate device (plate cage benezech, PCB) for cervical disease. MethodsBetween February 2011 and January 2013, 98 patients with cervical spondylosis who accorded with the inclusion criteria were treated with Zero-P in 49 cases (group A) and with PCB in 49 cases (group B). There was no significant difference in gender, age, disease type, disease duration, and disease segments between 2 groups (P>0.05). The Cobb angle, short-form 36 health survey scale (SF-36 scale), Japanese Orthopedic Association (JOA) score, postoperative dysphagia cases, neck disability index (NDI), and visual analogue scale (VAS) score were compared between 2 groups. ResultsThe operation time and intraoperative blood loss of group A were significantly less than those of group B (t=4.089, P=0.000;t=3.587, P=0.001). The patients were followed up 3-36 months (mean, 18.5 months). No loosening or breaking of internal fixation and bone absorption or collapse occurred in the other patients except 2 patients who suffered from screw loosening at 3 months after operation. Within 6 months after operation, dysphagia occurred in 8 cases (16.33%) of group A and in 13 cases (26.53%) of group B, showing significant difference (χ2=10.616, P=0.001). At last follow-up, JOA score, VAS score, NDI, SF-36 scale, and Cobb angle were significantly improved when compared with preoperative ones in 2 groups (P<0.05);the other indexes of group A were significantly better than those of group B (P<0.05) except SF-36 scale and Cobb angle (P>0.05). The excellent and good rate of JOA score was 81.63% in group A and 71.43% in group B, showing significant difference (χ2=4.346, P=0.037). ConclusionZero-P and PCB can get good results in treatment of cervical disease, but the Zero-P is better than PCB in reducing postoperative dysphagia because less wounds and strong stability.
ObjectiveTo summarize the progress in mechanisms of resistance to trastuzumab in treating human epidermal growth factor receptor 2 (HER2)-positive breast cancer. MethodsBy searching Pubmed and CNKI, the literatures of mechanisms of resistance to trastuzumab in treating HER2-positive breast cancer were reviewed. ResultsThe possible mechanism of resistance to trastuzumab are thought to include HER2 gene amplification and high protein expression; impaired access of trastuzumab to HER2; bidirectional crosstalk between ER and HER2; HER2 downstream signal transduction pathway activation; expansion expression of other RTKs and membrane-associated receptors; alterations in apoptosis and cell cycle control as well as multi-gene mutation, etc. ConclusionsMechanisms of trastuzumab resistance in HER2-positive breast cancer is complicated, a better understanding will be achieved by comprehensive analysis of existing possible mechanisms. The outcome of HER2-positive breast cancer patients who developed resistance to trastuzumab will be improved by appropriate multi-target regime.
Objective To investigate the early effectiveness of Zero-profile interbody fusion system (Zero-P) in the treatment of cervical disc protrusion. Methods Between October 2010 and June 2012, 25 patients with cervical disc protrusion underwent anterior cervical discectomy and fusion (ACDF) using the Zero-P system. There were 15 males and 10 females, aged from 35 to 68 years (mean, 49 years). The disease duration was 3-26 months (mean, 10.5 months). Single segment was involved in all cases (2 cases in C3, 4, 5 cases in C4, 5, 11 cases in C5, 6, and 7 cases in C6, 7). The operation time and blood loss were recorded and analyzed. The visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, and neck disability index (NDI) were used to assess pain and nerve function improvement; the cervical Cobb angle was measured on the X-ray films before and after operation; according to Pitzen’s criteria, intervertebral fusion was evaluated. Results The operation was successful in 25 patients, with no severe complication. The average blood loss was 42.6 mL (range, 20-120 mL). The average operation time was 63.6 minutes (range, 45-90 minutes). Primary healing of incision was obtained in all cases; no injury of spinal cord and nerve root, cerebrospinal leakage, or deep infection occurred. The patients were followed up 6-23 months (mean, 14.5 months). No Cage subsidence and loosening, breaking, or pulling-out were observed. The symptoms and curvature of the cervical spine were obviously improved in all patients after operation. The VAS score, JOA score, NDI, and the cervical Cobb angle at 3 months and last follow-up showed significant differences when compared with preoperative ones (P lt; 0.05), but no significant difference was found between at 3 months and at last follow-up (P gt; 0.05). The interbody fusion was achieved in each operated segment of all patients according to Pitzen’s criteria. Conclusion The early effectiveness of ACDF with Zero-P system is satisfactory in treatment of cervical disc protrusion because it has the advantages of short operation time, less bleeding, good stability and restoration of the cervical alignment.
There is a shared problem in current optical imaging technologies of how to obtain the optical parameters of biological tissues with complex profiles. In this work, an imaging system for obtaining the optical parameters of biological tissues with complex profile was presented. Firstly, Fourier transformation profilometry was used for obtaining the profile information of biological tissues, and then the difference of incident light intensity at different positions on biological tissue surface was corrected with the laws of illumination, and lastly the optical parameters of biological tissues were achieved with the spatial frequency domain imaging technique. Experimental results indicated the proposed imaging system could obtain the profile information and the optical parameters of biological tissues accurately and quickly. For the slab phantoms with height variation less than 30 mm and angle variation less than 40º, the maximum relative errors of the profile uncorrected optical parameters were 46.27% and 72.18%, while the maximum relative errors of the profile corrected optical parameters were 6.89% and 10.26%. Imaging experiments of a face-like phantom and a human’s prefrontal lobe were performed respectively, which demonstrated the proposed imaging system possesses clinical application value for the achievement of the optical parameters of biological tissues with complex profiles. Besides, the proposed profile corrected method can be used to combine with the current optical imaging technologies to reduce the influence of the profile information of biological tissues on imaging quality.
Objective To analyze the changes of gene expression profiles during the process that human bonemarrow mesenchymal stem cells (hBMSCs) are induced to differentiate into cardiomyogenic cells with 5-azacytidine (5-aza). Methods hBMSCs were isolated from marrow of obsolete ribs and induced with 5-aza. Then immunocytochemicalstaining was used to detect the expressions of α-actin, cardiac troponin T (cTnT), and connexin 43, and the percentage ofcTnT positive cells was tested with flow cytometry. In the process of differentiation, variation of gene expression was screenedwith Genechi ps Operating System of human gene expression profiles. And the differentially expressed genes were functionallyanalyzed and hierarchical clustered. Results When BMSCs were induced in vitro with 5-aza, part of the cells turnedinto myogenic cells morphologically. Before induction, immunocytochemical staining for α-actin and cTnT showed sl ightpositive and for connexin 43 showed negative. While after 3 weeks of induction, immunocytochemical staining for α-actin,cTnT, and connexin 43 showed all positive. With flow cytometry, the percentage of cTnT positive cells was 7.43% ± 0.02%before induction, but it was 49.64% ± 0.05% after induction. During differentiation, 1 814 differentially expressed geneswere reported by gene chi ps. Of them, 647 genes were divided into 5 groups with hierarchical clustering. They had variousbiological functions, involving signal transduction, cell metabol ism, prol iferation, differentiation, development, andtopogenesis. Conclusion hBMSCs can differentiate into cardiomyogenic cells with the induction of 5-aza in vitro. Multi plegenes related with signal transduction, transcri ption, and growth factors are involved during this process.
Objective To evaluate the early outcome of anterior cervical discectomy and fusion (ACDF) using a Zero-profile implant system (Zero-P) for interbody fusion in the treatment of cervical spondylosis. Methods Between March 2010 and June 2011, 25 patients with cervical spondylosis underwent ACDF with Zero-P. There were 13 males and 12 females with an average age of 44.2 years (range, 26-67 years), including 14 cases of nerve root cervical spondylosis, 6 cases of spinal cervical spondylosis, and 5 cases of mixed cervical spondylosis. The disease duration was 3-120 months (median, 25 months). Single segment was involved in 20 cases, 2 segments in 4 cases, and 3 segments in 1 case. A total of 31 Zero-P were implanted (3 at C3, 4, 8 at C4, 5, 12 at C5, 6, and 8 at C6, 7). Primary cervical operation was performed in 23 cases and re-operation in 2 cases. Before and after operation, the height of intervertebral space and the cervical Cobb angle were measured; clinical outcome was evaluated using visual analogue scale (VAS) score for pain in the neck and upper limb, and Japanese Orthopaedic Association (JOA) score for myelopathy; and intervertebral fusion and the incidence of dysphagia were also observed. Results All incisions healed by first intention. All the patients were followed up 12-16 months (mean, 13.9 months). Interbody bone fusion was obtained, and the fusion time was 2.7-6.0 months (mean, 3.8 months). Three patients had dysphagia after operation; symptom disappeared at 1 week and 3 months after operation in 2 cases and 1 case, respectively. No fixation loosening, subsidence, or breakage occurred. The height of intervertebral space was significantly improved (P lt; 0.05) from (4.5 ± 0.5) mm at preoperation to (6.0 ± 0.7) mm at 1 week and (5.7 ± 0.6) mm at 12 months after operation; the cervical Cobb angle was significantly improved (P lt; 0.05) from (11.9 ± 6.1)° at preoperation to (21.2 ± 4.1)° at 1 week and (20.2 ± 3.7)° at 12 months after operation; and there was no significant difference between at 1 week and 12 months after operation (P gt; 0.05). The VAS score was significantly reduced (P lt; 0.05) from 7.1 ± 0.8 at preoperation to 1.9 ± 0.8 at 3 months and 1.0 ± 0.5 at 12 months after operation; the JOA score was significantly increased (P lt; 0.05) from 9.6 ± 1.3 at preoperation to 13.5 ± 1.0 at 3 months and 14.9 ± 1.0 at 12 months after operation; and there was significant difference between at 3 months and at 12 months after operation (P lt; 0.05). Conclusion The early outcome of ACDF using a Zero-P in the treatment of cervical spondylosis is satisfactory and reliable, and it can restore and maintain the cervical alignment and disc height, and disc has low incidence of postoperative dysphagia.
