The reverse phase nystagmus is not uncommon in clinical practice.Inadequate understanding brings great confusion to clinical diagnosis and treatment,which leads to misdiagnosis frequently and also increases the eco-nomic burden on patients.The purpose of this paper is to summarize and analyze the mechanism,characteristics and clinical significance of reverse phase nystagmus,to help clinicians better understand the significance of inversion nys-tagmus in benign paroxysmal positional vertigo,in order to achieve accurate and efficient diagnosis and treatment of these patients.

Vertebral refracture following percutaneous vertebral augmentation (PVA) is commonly seen in elderly patients with osteoporotic thoracolumbar compression fractures (OTLCF). It can lead to recurrent pain, loss of vertebral height, progression of kyphosis, and even neurological dysfunction, significantly impairing patients′ quality of life. Current diagnosis and treatment face multiple challenges, including high misdiagnosis rate, difficulty in choosing between surgical and non-surgical treatment options, lack of standardized surgical protocols, interference from intralesional bone cement during procedures, inadequate stability of internal fixation in osteoporotic bone, and suboptimal compliance of anti-osteoporotic therapy. Establishing a standardized diagnostic and therapeutic framework is urgently needed. To standardize the management process and improve outcomes for vertebral refractures after PVA in elderly OTLCF patients, Spinal Trauma Group of the Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field to develop Guideline for the diagnosis and treatment of vertebral refracture after percutaneous vertebral augmentation in elderly patients with osteoporotic thoracolumbar compression fractures ( version 2025), based on current literature and clinical experience, and adhering to principles of scientific rigor and clinical applicability. A total of 11 recommendations were proposed, encompassing diagnosis, treatment, and rehabilitation of vertebral refracture after PVA in elderly patients with OTLCF, aiming to provide a foundation for a standardized management.

Acute symptomatic osteoporotic thoracolumbar compression fracture (ASOTLF) can lead to chronic low back pain, kyphosis deformity, pulmonary dysfunction, loss of mobility, and even life-threatening complications. Vertebral augmentation is currently the mainstream treatment method for this condition. In 2019, the Editorial Board of Chinese Journal of Trauma and the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association collaboratively led the development of Clinical guideline for vertebral augmentation for acute symptomatic osteoporotic thoracolumbar compression fractures. Six years later, with advances in clinical diagnosis and treatment techniques as well as accumulating evidence in related fields, the 2019 guideline requires updating. To this end, the Spinal Trauma Group of Orthopedic Surgeons Branch of Chinese Medical Doctor Association, the Spinal Health Professional Committee of China Human Health Science and Technology Promotion Association, and the Minimally Invasive Orthopedics Professional Committee of Shaanxi Medical Doctor Association have organized experts in the field to develop the Clinical guideline for vertebral augmentation of acute symptomatic osteoporotic thoracolumbar compression fractures ( version 2025) , based on the latest evidence-based medical researches. This guideline incorporates 3 recommendations retained from the 2019 version with updated strength of evidence, along with 12 new recommendations. It provides recommendations from six aspects of diagnosis, pain management, treatment option selection, prevention of postoperative complications, anti-osteoporosis therapy, and postoperative rehabilitation, aiming to provide a reference for standard treatment of vertebral augmentation for ASOTLF in hospitals at all levels.

Objective To analyze the correlation between serum circular RNA-ATAD1(circ-ATAD1)and microRNA-140-3p(miR-140-3p)expression and the prognosis of cervical cancer patients.Methods From March 2018 to March 2020,a total of 146 patients with cervical cancer(study group),146 patients with benign uterine lesions(benign uterine lesions group),and 146 healthy people who underwent the physical examina-tion(control group)in Cangzhou Hospital of Integrated TCM-WM·Hebei were selected as the research sub-jects.Real-time quantitative PCR was used to detect serum levels of miR-140-3p and circ-ATAD1.The Kap-lan-Meier method was used to analyze the correlation between serum circ-ATAD1 and miR-140-3p expression and the prognosis of cervical cancer patients.Multivariate Cox regression model was used to analyze the influ-encing factors of prognosis of cervical cancer patients.Results The serum circ-ATAD1 level in the study group was significantly higher than those in the control group and benign uterine lesion group(P＜0.05),and miR-140-3p was significantly lower than those in the control group and benign uterine lesion group(P＜0.05).The proportions of patients with low expression of miR-140-3p and high expression of circ-ATD1 in the cervical cancer patients with vaginal infiltration,lymph node metastasis,and FIGOstage Ⅲ-Ⅳ were higher than those in the cervical cancer patients with no vaginal infiltration,no lymph node metastasis,and FIGO stage Ⅰ-Ⅱ(P＜0.05).The 3-year survival rate of cervical cancer patients with high circ-ATD1 expression was lower than that of patients with low circ-ATD1 expression(30.14％vs.64.38％,P＜0.001).The 3-year survival rate of cervical cancer patients with high miR-140-3p expression was higher than that of patients with low miR-140-3p expression(61.64％vs.32.88％,P＜0.001).FIGO stage,circ-ATAD1,lymph node metas-tasis and miR-140-3p were factors affecting the prognosis of cervical cancer patients(P＜0.05).Conclusion The serum level of circ-ATAD1 in patients with cervical cancer is significantly increased and the level of miR-140-3p is significantly decreased,the two are closely related to lymph node metastasis and FIGO stage in patients with cervical cancer,and are influencing factors for the prognosis of cervical cancer patients.

Objective To observe the mechanism of anti-hepatocellular carcinoma of salidroside.Methods H22 hepatocellular carcinoma cells were divided into control group(only fresh culture medium was replaced)and salidroside low-,medium-and high-dose groups,and the corresponding intervention was given in each group for 48 hours.Cellular proliferation activity was detected by cell counting kit(CCK)-8,the number of invasive cells was detected by Transwell assay,the number of autophagosomes was observed by using dansylcadaverine(MDC)staining method,the mRNA and protein expression levels of high mobility group protein 1(HMGB1)and autophagy-related genes yeast Atg6 homolog(Beclinl),microtubule-associated protein lA/lB-light chain 3(LC3 Ⅱ/Ⅰ)and sequestosome 62(p62)were detected accordingly by real-time quantitative polymerase chain reaction(qRT-PCR)and Western Blot,respectively.Results Compared with the control group,the cellular proliferation activity was decreased,the number of invading cells and autophagosomes were reduced in salidroside low-,medium-and high-dose groups,mRNA and protein expression level and of p62 were increased,and mRNA and protein expression levels of HMGB1,LC3-Ⅱ/Ⅰ and Beclin1 were decreased,the differences being statistically significant(P＜0.05),showing a dose-dependent manner.Conclusion Salidroside may inhibit the proliferation and invasion of hepatocellular carcinoma cells by down-regulating the expression of HMGB1 and autophagy level.

Objective:To explore the epidemiological characteristics, imaging findings, pulmonary function changes, dust exposure situations, and treatment outcomes of accelerated silicosis through an analysis of existing literature.Methods:In December 2024, relevant literature from January 1, 1965 to December 15, 2024 was retrieved through the China National Knowledge Infrastructure (CNKI), Wanfang Database, VIP Database, EMbase, and PubMed databases. Keywords included "rapidly progressive silicosis" "accelerated silicosis" "subacute silicosis""artificial stone" and related terms. By incorporating, analyzing, and retrieving data from literatures, a comprehensive review of the epidemiology, clinical features, treatment options, and prognosis of fast forward silicosis was conducted.Results:A total of 72 literatures were included, including 23 cohort studies, 28 case reports, 3 case-control studies, and 18 cross-sectional studies. The average age of all 1794 patients was 33.67 years, with an average dust exposure duration of 5.58 years. The primary occupations associated with accelerated silicosis were stone processing, mining, and artificial quartz stone manufacturing. Imaging findings predominantly included small nodules, ground-glass opacities, and massive fibrosis. Antifibrotic treatment at the early stage of the disease could clearly delay disease progression. However, dust concentrations in workplaces were significantly above safety limits, with inadequate protective measures.Conclusion:Accelerated silicosis is characterized by its rapid onset, swift progression, and unfavorable prognosis. However, it has not garnered adequate attention in the present context. Reliable standard and guidelines are urgently needed to guide clinical diagnosis and treatment.
