The pathological processes of neurodegeneration and neurodegenerative changes after traumatic brain injury (TBI) are closely related to microglia. The pathophysiological functions of microglia are closely correlated to their different cell subtypes. Disease-related microglia (DAM) are a special subtype of microglia, which recently discover on the lesions of degenerative diseases of the central nervous system. DAM are identified as important cells that induce neurodegeneration. The in-depth discussion of DAM role in pathological mechanism of neurodegeneration after TBI provides new clues for understanding and treating neurodegeneration after TBI; therefore, this article focuses on the above content and summarizes the research progress of DAM and neurodegeneration after TBI.

Objective To investigate the predictive value of serum oncogene[proliferation-related gene(C-myc),transformation gene(N-ras),silk/threonine kinase 1(PLK1),fibroblast growth factor 2(FGF2)]protein levels in patients with hepatitis B associated hepatocellular carcinoma(HCC)after hepatic arterial chemoem-bolization(TACE).Methods A total of 127 patients with hepatitis B-associated hepatocellular carcinoma ad-mitted to a hospital from July 2016 to January 2021 were selected and divided into death group and survival group according to the follow-up results.The serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels were determined by double-antibody sandwich enzyme-linked immunosorbent assay.Univariate and multivari-ate Cox analysis were used to analyze the risk factors of serum oncogene C-myc,N-ras,PLK1 and FGF2 pro-tein levels in patients with hepatitis B-associated hepatocellular carcinoma after TACE.The receiver operating characteristic curve was used to evaluate the prognostic value of the serum oncogene C-myc,N-ras,PLK1 and FGF2 protein levels,and the patients were divided into high expression group and low expression group ac-cording to the corresponding cutoff value.Kaplan-Meier survival curve was used to evaluate the prognosis of different serum oncogene C-myc,N-ras,PLK1 and FGF2 protein level.Results Multivariate Cox regression a-nalysis indicated that TNM stage Ⅲ to Ⅳ(HR=2.998,95％CI:1.239-7.257),portal vein metastasis(HR=3.737,95％CI:1.941-7.193),abdominal metastasis(HR=3.482,95％CI:1.709-7.097),Child-Pugh grade B(HR=2.587,95％CI:1.045-6.406),high serum oncogene C-myc protein level(HR=1.224,95％CI:1.090-1.374),high serum oncogene N-ras protein level(HR=1.218,95％CI:1.097-1.353),high serum oncogene PLK1 protein level(HR=1.237,95％CI:1.110-1.379)and high serum oncogene FGF2 protein level(HR=1.141,95％CI:1.060-1.228)were independent risk factors for the prognosis of hepatitis B-asso-ciated hepatocellular carcinoma patients after TACE(all P＜0.05).The overall survival rate of low expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level was significantly higher than that of high expression group of serum oncogene C-myc,N-ras,PLK1,FGF2 protein level,the difference was statistically significant(all P＜0.001).Conclusion Serum oncogene C-myc,N-ras,PLK1,FGF2 protein levels have predic-tive value for the prognosis of patients with HBV-related liver cancer after TACE.

The pathological process continues to evolve for a long time after acute phase of traumatic brain injury (TBI), often coupling with neurodegeneration and neurodegenerative complications. Microvascular dysfunction and blood-brain barrier (BBB) dysfunction caused by neurovascular unit (NVU) dysfunction are closely related to the pathological process of many neurodegenerative diseases. The study on the pathological mechanism of neurovascular unit dysfunction is a promising research field of TBI-related neurodegeneration, and also provides a new idea for the treatment of neurodegeneration after TBI. Therefore, this article mainly reviews these.

OBJECTIVES: To explore the safety and effectiveness of arthroscopic reconstruction of coracoclavicular ligament by suspensory fixation to manage the acute acromioclavicular joint dislocation. METHODS: From January 2016 to December 2017, 18 cases of acute acromioclavicular joint dislocation were carried out with arthroscopic reconstruction of coracoclavicular ligament by double Endobutton plate suspensory fixation. Anteroposterior view X-ray plain radiographs were obtained on the second day, 6 months and 12 months after the surgery, MRI was performed in 1 year after operation. Meanwhile, subjective and objective scoring were obtained by Vsual Analogue Scale (VAS), Rating Scale of the American Shoulder and Elbow Surgeons (ASES) and University of California at Los Angeles Shoulder Rating Scale (UCLA). RESULTS: All patients were followed up for 12 to 30 months (an average of 18 months). There was no patient with infection, neurovascular injury, loosening and breakage of internal fixation, re-dislocation of acromioclavicular joint, clavicular fracture, coracoid process fracture, etc. Postoperative X-ray showed that all acromioclavicular joints were completely relocated. The follow-up of MRI after 1 year showed no obvious dislocation of acromioclavicular joint and good recovery of acromioclavicular space. Postoperative shoulder joint function, VAS, ASES, UCLA and acromioclavicular distance were significantly improved compared with those before surgery, with statistically significant differences (all <0.05). CONCLUSIONS Arthroscopic reconstruction of coracoclavicular ligament by suspensory fixation to manage the acute acromioclavicular joint dislocation has the advantages of minimal invasive, rapid functional recovery and less complications and satisfactory early clinical results.

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Metastasis is the leading cause of cancer-related death. Despite extensive treatment, the prognosis for patients with metastatic cancer remains poor. In addition to conventional surgical resection, radiotherapy, immunotherapy, chemotherapy, and targeted therapy, various nanobiomaterials have attracted attention for their enhanced antitumor performance and low off-target effects. However, nanomedicines exhibit certain limitations in clinical applications, such as rapid clearance from the body, low biological stability, and poor targeting ability. Biomimetic methods utilize the natural biomembrane to mimic or hybridize nanoparticles and circumvent some of these limitations. Considering the involvement of immune cells in the tumor microenvironment of the metastatic cascade, biomimetic methods using immune cell membranes have been proposed with unique tumor-homing ability and high biocompatibility. In this review, we explore the impact of immune cells on various processes of tumor metastasis. Furthermore, we summarize the synthesis and applications of immune cell membrane-based nanocarriers increasing therapeutic efficacy against cancer metastases via immune evasion, prolonged circulation, enhanced tumor accumulation, and immunosuppression of the tumor microenvironment. Moreover, we describe the prospects and existing challenges in clinical translation.
