OBJECTIVE: To review the clinical characteristics of patients with traumatic spinopelvic dissociation (SPD) and explore the diagnostic and therapeutic methods. METHODS: A clinical data of 22 patients with SPD who underwent surgical treatment between March 2019 and August 2024 was retrospectively analyzed. There were 13 males and 9 females, with an average age of 35.5 years (range, 14-61 years). The causes of injury included falling from height in 16 cases, traffic accidents in 5 cases, and compression injury in 1 case. Sacral fractures were classified based on morphology into "U" type (9 cases), "H" type (7 cases), "T" type (4 cases), and "λ" type (2 cases). According to the Roy-Camille classification, there were 4 cases of type Ⅰ, 12 cases of type Ⅱ, 2 cases of type Ⅲ, and 4 cases of type Ⅳ. The Cobb angle was (35.7± 22.0)°. Sixteen patients were accompanied by lumbosacral trunk and cauda equina nerve injury, which was classified as grade Ⅱ in 5 cases, grade Ⅲ in 5 cases, and grade Ⅳ in 6 cases according to the Gibbons grading. The time from injury to operation was 2-17 days (mean, 5.7 days). Based on the type of sacral fracture and sacral nerve injury, 6 cases were treated with closed reduction and minimally invasive percutaneous sacroiliac screw fixation, 16 cases were treated with open reduction and lumbar iliac fixation (8 cases)/triangular fixation (8 cases). Among them, 11 patients with severe fracture displacement and kyphotic deformity leading to sacral canal stenosis or bony impingement within the sacral foramen underwent laminectomy and sacral nerve decompression. X-ray films and CT were reviewed during followed-up. The Matta score was used to evaluate the quality of fracture reduction. At last follow-up, the Majeed score was used to assess the functional recovery, and the Gibbons grading was used to evaluate the nerve function. RESULTS: All operations were successfully completed. All patients were followed up 8-64 months (mean, 20.4 months). Two patients developed deep vein thrombosis of the lower limbs, 2 had incision infections, and 1 developed a sacral pressure ulcer; no other complications occurred. Radiological examination showed that the Cobb angle was (12.0±6.8)°, which was significantly different from the preoperative one ( t=6.000, P<0.001). The Cobb angle in 16 patients who underwent open reduction was (14.9±5.5)°, which was significantly different from the preoperative one [(46.8±13.9)° ] ( t=8.684, P<0.001). According to the Matta scoring criteria, the quality of fracture reduction was rated as excellent in 8 cases, good in 7 cases, fair in 5 cases, and poor in 2 cases, with an excellent and good rate of 68.2%. Bone callus formation was observed at the fracture site in all patients at 12 weeks after operation, and bony union achieved in all cases at last follow-up, with a healing time ranging from 12 to 36 weeks (mean, 17.6 weeks). At last follow-up, the Majeed score was rated as excellent in 7 cases, good in 10 cases, fair in 4 cases, and poor in 1 case, with an excellent and good rate of 77.3%. One patient experienced a unilateral iliac screw breakage at 12 months after operation, but the fracture had already healed, and there was no loss of reduction. Among the 16 patients with preoperative sacral nerve injury, 11 cases showed improvement in nerve function (6 cases) or recovery (5 cases). CONCLUSION SPD with low incidence, multiple associated injuries, and high incidence of sacral nerve injury, requires timely decompression of the sacral canal for symptomatic sacral nerve compression, fractures reduction, deformities correction, and stable fixation.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Standardized clinical trial reporting is crucial for ensuring the scientific validity,reproducibility,and clinical translational value of reported results.The Consolidated Standards of Reporting Trials(CONSORT)statement,an internationally recognized guideline for randomized controlled trials(RCTs),has become an important reference standard for writing research papers in medicine since the 2010 version of CONSORT was published.With advancements in scientific research methodologies and the emergence of new forms of clinical trials,the CONSORT working group released an updated version in April 2025,published in journals such as The BMJ.Herein,we provide a systematic interpretation of the core revisions of CONSORT 2025,as well as a comparison with CONSORT 2010 to highlight the key differences.By providing practical,example-based recommendations,we aim to help domestic researchers apply the new guidelines efficiently,thereby improving the quality of clinical trial reports authored by domestic researchers.

A high-quality clinical trial protocol is the cornerstone for ensuring the scientific integrity and ethical compliance of a study.The Standard Protocol Items:Recommendations for Interventional Trials(SPIRIT)has become the international benchmark for developing clinical trial protocols since its release in 2013.To adapt to the developing trends of open science and patient-centered principles,the SPIRIT group completed a comprehensive update in 2025.While retaining its core structure,this updated guideline introduces a new open science module and incorporates several new elements,including patient and public involvement,trial monitoring,and data sharing,alongside substantial revisions of five pre-existing items.In this article,we critically examine the core revisions in SPIRIT 2025 and,through analysis of representative case studies,illustrate the practical application of the new reporting guideline in drafting trial protocols.Our goal is to to provide Chinese researchers with a valuable reference for understanding and implementing this new reporting guideline,thereby enhancing the quality and rigor of clinical trial protocols developed in the country.

Objective:To investigate the sedative effect of remimazolam on ICU elderly patients undergoing mechanical ventilation and its influence on circulatory system.Methods:Using a prospective research approach, 189 ICU elderly patients undergoing mechanical ventilation in Hebei Petro China Central Hospital from October 2021 to June 2023 were selected. The patients were divided into remimazolam group, dexmedetomidine group and propofol group by random number table method with 63 cases in each group. The patients in remimazolam group, dexmedetomidine group and propofol group were sedated with remimazolam, dexmedetomidine and propofol, respectively. The sedation standard time, sedation standard rate, sedation maintenance time and recovery time after drug withdrawal were compared among the three groups. The heart rate, mean arterial pressure (MAP), respiratory rate and pulse oxygen saturation (SpO 2) before medication (T 0) and medication for 15 min (T 1), 30 min (T 2), 1 h (T 3), 6 h (T 4), 12 h (T 5) were recorded. The incidences of bradycardia, hypotension, respiratory depression, body movement and delirium during sedation were recorded. Results:The sedation standard time and recovery time after drug withdrawal in remimazolam group were significantly shorter than those in dexmedetomidine group and propofol group: (22.27 ± 5.31) min vs. (29.45 ± 6.24) and (30.12 ± 5.87) min, (28.66 ± 7.06) min vs. (32.22 ± 6.85) and (34.34 ± 7.24) min, and there were statistical differences ( P<0.05); there were no statistical difference between dexmedetomidine group and propofol group ( P>0.05). The sedation standard rate in remimazolam group and dexmedetomidine group was significantly higher than that in propofol group: 87.43% (661/756) and 83.60% (632/756) vs. 72.49% (548/756), and there was statistical difference ( P<0.016 7); there was no statistical difference between remimazolam group and dexmedetomidine group ( P>0.016 7). There was no statistical difference in sedation maintenance time among the three groups ( P>0.05). There were no statistical difference in T 0 heart rate, MAP, respiratory rate and SpO 2 among the three groups ( P>0.05). The T 1 to T 5 heart rate and MAP in remimazolam group were significantly higher than those in dexmedetomidine group and propofol group, the T 2 to T 5 heart rate and MAP in dexmedetomidine group were significantly lower than those in propofol group, and there were statistical differences ( P<0.05). The T 2 to T 5 respiratory rate in remimazolam group was significantly lower than that in dexmedetomidine group, the T 1 to T 5 respiratory rate in remimazolam group and dexmedetomidine group was significantly higher than that in propofol group, and there were statistical differences ( P<0.05). The T 2 to T 5 SpO 2 in remimazolam group and dexmedetomidine group was significantly higher than that in propofol group, and there was statistical difference ( P<0.05). The incidence of bradycardia in remimazolam group was significantly lower than that in dexmedetomidine group: 7.94% (5/63) vs. 25.40% (16/63), the incidence of hypotension was significantly lower than that in propofol group: 6.35% (4/63) vs. 23.81% (15/63), and there were statistical differences ( P<0.016 7). The incidence of respiratory depression in remimazolam group and dexmedetomidine group was significantly lower than that in propofol group: 4.76% (3/63) and 1.59% (1/63) vs. 22.22% (14/63), and there was statistical difference ( P<0.016 7).

There was no statistical difference in the incidence of body movement among the three groups ( P>0.05). Conclusions:The effect of remimazolam sedation in ICU elderly patients undergoing mechanical ventilation is satisfactory, with little influence on circulation and respiratory system and few adverse reactions.

Medicine is essentially an anthropology, and the patient role is characterized by integrity and subjectivity. With the progress of science and technology and social development, the contemporary patient role has become alienated. The specific manifestations of patient role alienation were analyzed from four aspects, including the objectification of the patient role and the blurring of the patient boundaries in sociology, the objectification of the patient role and the indexing of patients’ pain in technology, the challenge of patient life and health rights and the alienation of informed consent rights in law, and the instrumentalization of patient role and the fragility of patient subjectivity in economics. This paper proposed that the coordination of technology and humanities, the return to the nature of patients, and the concern for the needs of patients are essential in the development of modern medicine.

OBJECTIVE: To investigate the surgical technique and effectiveness of titanium elastic nail (TEN) assisted retrograde channel screw implantation of superior pubic branch. METHODS: The clinical data of 31 patients with pelvic or acetabular fractures treated with retrograde channel screw implantation in superior pubic branch between January 2021 and April 2022 were retrospectively analyzed. Among them, 16 cases were implanted with assistance of TEN (study group) and 15 cases were implanted under the guidance of C-arm X-ray machine (control group). There was no significant difference in gender, age, cause of injury, Tile classification of pelvic fracture, Judet-Letournal classification of acetabular fracture, and time from injury to operation between the two groups ( P>0.05). The operation time, fluoroscopy times, and intraoperative blood loss of each superior pubic branch retrograde channel screw were recorded during operation. X-ray films and three-dimensional CT were reexamined after operation, the quality of fracture reduction was evaluated by Matta score standard, and the position of channel screw was evaluated by screw position classification standard. The fracture healing time was recorded during the follow-up, and the postoperative functional recovery was evaluated by Merle D'Aubigne Postel score system at last follow-up. RESULTS: Nineteen and 20 retrograde channel screws of superior pubic branch were implanted in the study group and the control group, respectively. The operation time, fluoroscopy times, and intraoperative blood loss of each screw in the study group were significantly less than those in the control group ( P<0.05). According to the postoperative X-ray films and three-dimensional CT, none of the 19 screws in the study group penetrated out of the cortical bone or into the joint, and the excellent and good rate was 100% (19/19); in the control group, there were 4 screws of cortical bone penetration, and the excellent and good rate was 80% (16/20); the difference between the two groups was significant ( P<0.05). Matta score standard was used to evaluate the quality of fracture reduction, there was no patient in the two groups with poor reduction results, and the difference was not significant between the two groups ( P>0.05). The incisions of the two groups healed by first intention, and there was no complication such as incision infection, skin margin necrosis, and deep infection. All patients were followed up 8-22 months, with an average of 14.7 months. There was no significant difference in healing time between the two groups ( P>0.05). At last follow-up, the difference in functional recovery evaluated by the Merle D'Aubigne Postel scoring system between the two groups was not significant ( P>0.05). CONCLUSION TEN assisted implantation technique can significantly shorten the operation time of retrograde channel screw implantation of superior pubic branch, reduce the times of fluoroscopy, and have less intraoperative blood loss and accurate screw implantation, which provides a new safe and reliable method for minimally invasive treatment of pelvic and acetabular fractures.

Objective:To study the relationship and the role of leptin in children with biliary atresia and hepatic fibrosis to provide a treatment basis for these patients.Methods:The clinical data of children with biliary atresia or congenital biliary dilatation (CBD) who underwent surgical treatment at the Department of General Surgery of Tianjin Children's Hospital from August 2019 to August 2021 were retrospectively analyzed. Of 31 children included in this study, there were 14 males and 17 females, with age of 60 (30, 63) d. Children with biliary atresia served as the study group ( n=26) and children with CBD served as the control group ( n=5). Leptin protein, α-smooth muscleactin (α-SMA) and phosphorylation of extracellular-regulated protein kinase 1/2 (p-ERK1/2) in liver tissues were detectd by immunohistochemistry (IHC). The expression level of leptin mRNA in liver tissues were detected by quantitative real-time reverse transcription polymerase chain reaction (qRT-PCR). Results:The average optical density values of leptin protein, α-SMA protein and p-ERK1/2 protein in the liver tissues of children in the study group were significantly higher than the control group ( P<0.05). The expression levels of leptin, α-SMA and p-ERK1/2 in liver tissues of children with biliary atresia significantly increased with increase in fibrosis degree ( P<0.05). The expression level of leptin in liver tissues of children with biliary atresia was positively correlated with the liver fibrosis grade ( rs=0.876), α-SMA ( r=0.723) and p-ERK1/2 ( r=0.725) ( P<0.01). The results of qRT-PCR showed that the content of leptin mRNA in liver tissues of children with biliary atresia was significantly higher than that of children with CBD ( P<0.05). Conclusion:Expressions of leptin increased with aggravation of degrees of hepatic fibrosis in biliary atresia. Leptin may be involved in activation of HSCs through the ERK1/2 signaling pathway in the process of hepatic fibrosis due to biliary atresia.

Objective: To evaluate the status and influencing factors of the mental health of patients with COVID-19 during isolation treatment. Methods: From February 2nd to 16th, 2020, 106 COVID-19 patients were anonymously investigated for their mental health status using onlinequestionnaires (including Patient Health Questionnaire-9, Generalized Anxiety Disorder Scale-7, Patient Health Questionnaire-15 scales). The patients were from Tongji Hospital Affiliated to Tongji Medical College ofHuazhong University of Science and Technology. After data processing, SPSS19.0 was used for statistical analysis. Results: Of the 106 COVID-19 patients, 46 were male and 60 were female, with an age of (35.90±11.92) years. The detection rates of depression, anxiety and somatic symptoms in those patients were 49.06% (52/106) , 56.60% (60/106) and 69.81% (74/106) respectively. The severe cases of depression (scale score greater than 19) , anxiety (scale score greater than 14) and somatic symptoms (scale score greater than 14) accounted for 9.43% (10/106) , 15.09% (16/106) and 20.75% (22/106) respectively. In addition, 67.92% (72/106) of the patients had sleep problems, 24.53% (26/106) had self-mutilating or suicidal thoughts, and 28.30% (30/106) required psychological counseling—all of which were at significantly higher percentages than those of the general population. Only 39.62% (42/106) of the examined patients had neither deression nor anxiety. By using the non-parametric test of rank conversion for analysis, and the results showed that both married patients and nucleic-acid-positive patients had more severe depressions, and both married patients and anoxemicpatients had more severe somatic symptoms. Conclusion This mental health assessment showed that depression, anxiety, and various somatic symptoms exist among the COVID-19 patients, and therefore early identification and intervention should be conducted to avoid extreme events such asself-mutilating or suicidal impulsivity, with a greater focus on both married patients and patients with severe symptoms.
