Anterior cervical decompression and fusion (ACDF) treatment for cervical spondylosis has been more than half a century, and achieved good clinical results. However, with the continuous extension of follow-up time, the fusion segment-associated postoperative complications emerged gradually. Reserved cervical stability and activity, the concept of non-fusion was born. As a non-fusion technique, cervical artificial disc replacement (CADR) developed rapidly. With the continuous development of artificial prosthesis materials and design concepts, and specification and proficiency of surgical procedures, CADR has achieved better short- and mid-term clinical efficacy than ACDF. Compared with ACDF, the main advantages of CADR are that the postoperative recovery is quick, the activity and stability of cervical vertebra are maintained, the height of cervical intervertebral space is restored, and the stress of adjacent segments and the rate of surgical renovation are reduced. In clinical work, as an emerging technology, CADR requires spine surgeons to control the surgical indications, contraindications, and patients’ conditions strictly. This article reviews the research progress of CADR in order to provide new ideas for clinical treatment of cervical spondylosis.
ObjectiveTo understand the current progress of surgical treatment, radiotherapy, chemical drug therapy, endocrine therapy, targeted therapy, and immunotherapy of metaplastic breast cancer (MBC), so as to provide reference for the clinical therapy selection of MBC. MethodThe literature relevant to MBC therapy research in recent years was comprehensively reviewed. ResultsAt present, the pathogenesis of MBC was not clear. The histopathology of MBC was more complex and the prognosis was poor. Compared with the invasive ductal carcinoma, the MBC patients had older age of onset, larger tumor diameter, faster growth and stronger invasiveness. The simple mastectomy was currently used in surgical treatment. The axillary lymph node involvement rate of MBC patients was lower, so the sentinel lymph node biopsy was widely used. The chemical drug therapy, endocrine therapy, and targeted therapy had limited effects on MBC patients. However, with its unique molecular expression by the genomic analysis of MBC and rise of precision medicine, targeted therapy and immunotherapy had become current research hotspots, providing potential therapeutic strategies for MBC patients. ConclusionsDue to the complex histopathology and poor prognosis of MBC, and most research on MBC is retrospective studies, lacking sufficient prospective studies with sufficient sample size, so there is currently no clear consensus on the optimal treatment method for MBC. In order to better improve prognosis of MBC patients, further in-depth research on MBC histopathology, prospective studies with sufficient sample size, and development of targeted and effective therapeutic drugs are needed in the future.
Facial aging is caused by several aspects involving skin, its deep soft tissue (fat, muscles, fascia ligaments, etc), and bones. The skin presents deepen wrinkles, darker, drying, and roughness. Volume loss and sag caused by gravity can be seen in deep soft tissue. And selective absorption can be seen in bones. At present, to combat facial aging caused by different causes, we have adopted comprehensive treatment methods such as facial rhytidectomy, embedded wire ascension, autogenous fat graft, hyaluronic acid or botulinum toxin injection, and optoelectronic techniques, etc.
Robotic gastric cancer surgery had developed rapidly in recent years, and its clinical application had come a long way. More and more studies had demonstrated that the robotic gastric cancer surgery was a safe and feasible procedure, and showed the technical advantages in the lymph node dissection, bleeding control, precise surgery, and postoperative recovery over laparoscopic surgery. However, some limitations such as the high surgical costs, lack of high-quality evidence, insufficient intelligence limited the development of robotic gastric cancer surgery. In the future, with more high-quality evidence-based medicine research and the development of intelligent surgical robots, the robotic gastric cancer surgery will be further standardized and promoted. We believe that robotic gastric cancer surgery will become the mainstream of minimally invasive surgery for the treatment of gastric cancer.
腹股沟疝和痔一样是人类独有的疾病，这是因为人是直立的缘故，当然，猩猩是否也有此问题尚未见报道。在胚胎发育和解剖上，腹股沟有薄弱之处是重要因素，老年人腹股沟部筋膜、肌肉弱化也是重要因素，许多论著和医生经验均有论述。
ObjectiveTo summarize the progress in treatment of unstable atlas fracture, the existing problems, and the research direction.MethodsRelated literature at home and abroad was reviewed. The stability evaluation of atlas fracture and treatment methods were introduced, and the selection of surgical approach and fixation instruments in treatment of unstable atlas fracture were summarized and analyzed.ResultsAt present, atlas fractures are considered as unstable fractures except single anterior arch fractures with complete transverse ligament or simple posterior arch fractures. The treatment of unstable atlas fracture has been developed from nonsurgical treatment and traditional fusion surgery to single-segment fixation. Nonsurgical treatment is less effective, while traditional fusion surgery has a disadvantage of limited the motion of the upper cervical spine. Single-segment fixation can not only restore and fix the fracture, but also preserve the upper cervical motion function. Single-segment fixation approaches include posterior and transoral approaches, and the fixation instruments are being constantly improved, mainly including screw-rod system, screw-plate system, and plate system.ConclusionFor unstable atlas fracture, single-segment fixation is an ideal surgical method, and has more advantages when compared with nonsurgical treatment and traditional fusion surgery. Single-segment fixation via transoral approach is more direct for atlas anterior arch fracture reduction, but there is a high risk of infection; and single-segment fixation via posterior approach is less effective for the reduction of atlas anterior arch fracture. Therefore, a better reduction method should be explored.
Acute respiratory distress syndrome is one of the forms of respiratory failure that seriously threaten human life. It has the characteristics of very high morbidity, mortality and hospitalization costs. How to treat acute respiratory distress syndrome to improve the quality of life of patients is particularly important. Mechanical ventilation is an important treatment for acute respiratory distress syndrome. This article will review the progress in mechanical ventilation therapy for acute respiratory distress syndrome, including non-invasive mechanical ventilation and invasive mechanical ventilation (tidal volume, lung recruitment, positive end-expiratory pressure, prone position ventilation, and high-frequency oscillatory ventilation), aiming to provide basis and reference for future exploration of the treatment direction of acute respiratory distress syndrome.
Objective To review the advances in diagnosis and treatment of acute scaphoid fractures. Methods The characteristic, classification, diagnosis, and treatment of acute scaphoid fractures were reviewed and summarized. Results As one of the common fracture in hand, scaphoid fractures are generally classified as either undisplaced and stable or displaced and unstable. CT and MRI has best diagnostic specificity and sensitivity respectively. Most undisplaced and stable fractures can be treated successfully by plaster immobilization, whereas the displaced and unstable fractures have great prognosis after open reduction and internal fixation. Conclusion Acute scaphoid fractures should be diagnosed and treated at an early stage, and choose the appropriate treatment according to the location and stability of the fracture.
ObjectiveTo summarize research progress of comprehensive treatment based on gene therapy, immunotherapy, and targeted therapy in recent years in order to improve understanding and treatment level of triple negative breast cancer (TNBC).MethodThe literatures about TNBC treatment in recent 5 years were reviewed and summarized.ResultsTNBC was more invasive than other types of breast cancer due to its lack of targeted receptors, and its recurrence and metastasis were earlier. The treatment plan was still mainly surgical treatment, supplemented by the chemotherapy and radiotherapy.ConclusionsAlthough recent studies of TNBC in surgical treatment, chemoradiotherapy, targeted therapy and other aspects have shown a good clinical application prospect, more evidences of clinical trials with large samples are still needed. With the deepening of molecular mechanism research, endocrine therapy and targeted drug therapy, including androgen-receptor-positive, have provided some new ideas for treatment of TNBC.
