Background/Aims: Metabolic dysfunction-associated steatohepatitis (MASH) is a significant risk factor for gallstone formation, but mechanisms underlying MASH-related gallstone formation remain unclear. Golgi membrane protein 1 (GOLM1) participates in hepatic cholesterol metabolism and is upregulated in MASH. Here, we aimed to explore the role of GOLM1 in MASH-related gallstone formation. Methods: The UK Biobank cohort was used for etiological analysis. GOLM1 knockout (GOLM1-/-) and wild-type (WT) mice were fed with a high-fat diet (HFD). Livers were excised for histology and immunohistochemistry analysis. Gallbladders were collected to calculate incidence of cholesterol gallstones (CGSs). Biles were collected for biliary lipid analysis. HepG2 cells were used to explore underlying mechanisms. Human liver samples were used for clinical validation. Results: MASH patients had a greater risk of cholelithiasis. All HFD-fed mice developed MASH, and the incidence of gallstones was 16.7% and 75.0% in GOLM1-/- and WT mice, respectively. GOLM1-/- decreased biliary cholesterol concentration and output. In vivo and in vitro assays confirmed that GOLM1 facilitated cholesterol efflux through upregulating ATP binding cassette transporter subfamily G member 5 (ABCG5). Mechanistically, GOLM1 translocated into nucleus to promote osteopontin (OPN) transcription, thus stimulating ABCG5-mediated cholesterol efflux. Moreover, GOLM1 was upregulated by interleukin-1β (IL-1β) in a dose-dependent manner. Finally, we confirmed that IL-1β, GOLM1, OPN, and ABCG5 were enhanced in livers of MASH patients with CGSs. Conclusions In MASH livers, upregulation of GOLM1 by IL-1β increases ABCG5-mediated cholesterol efflux in an OPN-dependent manner, promoting CGS formation. GOLM1 has the potential to be a molecular hub interconnecting MASH and CGSs.

OBJECTIVE: To evaluate the clinical efficacy and safety of Yangxue Qingnao Pills (YXQNP) combined with amlodipine in treating patients with grade 1 hypertension. METHODS: This is a multicenter, randomized, double-blind, and placebo-controlled study. Adult patients with grade 1 hypertension of blood deficiency and Gan (Liver)-yang hyperactivity syndrome were randomly divided into the treatment or the control groups at a 1:1 ratio. The treatment group received YXQNP and amlodipine besylate, while the control group received YXQNP's placebo and amlodipine besylate. The treatment duration lasted for 180 days. Outcomes assessed included changes in blood pressure, Chinese medicine (CM) syndrome scores, symptoms and target organ functions before and after treatment in both groups. Additionally, adverse events, such as nausea, vomiting, rash, itching, and diarrhea, were recorded in both groups. RESULTS: A total of 662 subjects were enrolled, of whom 608 (91.8%) completed the trial (306 in the treatment and 302 in the control groups). After 180 days of treatment, the standard deviations and coefficients of variation of systolic and diastolic blood pressure levels were lower in the treatment group compared with the control group. The improvement rates of dizziness, headache, insomnia, and waist soreness were significantly higher in the treatment group compared with the control group (P<0.05). After 30 days of treatment, the overall therapeutic effects on CM clinical syndromes were significantly increased in the treatment group as compared with the control group (P<0.05). After 180 days of treatment, brachial-ankle pulse wave velocity, ankle brachial index and albumin-to-creatinine ratio were improved in both groups, with no statistically significant differences (P>0.05). No serious treatment-related adverse events occurred during the study period. CONCLUSIONS Combination therapy of YXQNP with amlodipine significantly improved symptoms such as dizziness and headache, reduced blood pressure variability, and showed a trend toward lowering urinary microalbumin in hypertensive patients. These findings suggest that this regimen has good clinical efficacy and safety. (Registration No. ChiCTR1900022470).

OBJECTIVE: To observe the clinical effect and safety of Lu'e Biyan Formula (LBF) combined with loratadine in the treatment of moderate to severe allergic rhinitis (AR) patients with Fei (Lung)-qi deficiency-coldness (FQDC) syndrome. METHODS: From September 2023 to December 2024, moderate to severe AR patients with FQDC syndrome were recruited from the Outpatient Department of Integrated Traditional Chinese and Western Medicine for Pulmonary Diseases Part 1, China-Japan Friendship Hospital. Participants were randomly assigned to a test group and a control group by using a random number table at a ratio of 1:1. Both groups received oral loratadine tablets (10 mg, once daily) for 2 weeks. In addition, the test group received oral LBF (30 mL, twice daily), and the control group received a placebo of LBF. Changes in the Total Nasal Symptom Score (TNSS), Total Non-nasal Symptom Score (TNNSS), Visual Analog Scale (VAS), Rhinoconjunctivitis Quality of Life Questionnaire (RQLQ), and Chinese medicine (CM) syndrome scores before and after treatment were compared between groups. Moreover, the total effective rates and disease recurrence rates were compared. Adverse events (AEs) during the study period were also recorded. RESULTS: Totally 109 participants were recruited, and the full analysis set included 105 cases, 54 in the test group and 51 in the control group. Compared with the pre-treatment values, the scores of sneezing, runny nose, nasal obstruction, nasal itching, TNSS, TNNSS, VAS, RQLQ, and CM syndrome were significantly reduced in both groups at 1 and 2 weeks post-treatment and 12 weeks post-drug withdrawal (P<0.01). After treatment, the aforementioned scores in the test group were all markedly lower than those in the control group (P<0.01). Moreover, the total effective rate in the test group was higher than that in the control group (98.15% vs. 70.59%, P<0.01). After 12 weeks of drug withdrawal, there was no significant difference in the recurrence rate between groups (13.21% vs. 22.22%, P>0.05). No obvious AEs were observed in either group following treatment. CONCLUSIONS The combination of LBF with loratadine can effectively alleviate the symptoms of moderate to severe AR patients with FQDC syndrome, thereby improving their quality of life. This therapy demonstrated both precise effect and high safety. (Trial registration No. ITMCTR2025000589).

Objective To understand the clinical applicability and implementation of expert consensus on the implementation and removal of protective restraints in psychiatry,and to provide references for promoting the standardized practice of psychiatric protective restraints and updating the consensus.Methods By the convenience sampling method,a questionnaire survey was conducted among nurses from 480 hospitals in 30 provinces from June 15 to July 15,2024.The survey was conducted using the instrument for evaluating clinical applicability of guide-lines(version 2.0)and a self-compiled questionnaire on the clinical implementation of the restraint consensus.Results A total of 7,844 valid questionnaires were collected,with a valid questionnaire recovery rate of 93.78％.The results of clinical applicability scoring showed that the consensus had the lowest availability score(64.72％)and the highest acceptability score(76.74％).The results showed that nurses' receiving training and the level of their hospitals were the main influencing factors for scores in various dimensions(P＜0.05).4,774 participants(87.42％)believed that the application of consensus could enhance the standardization of nurses' restraint operations.The safety rate of the restraint consensus was 79.51％,and the economic ratio was 76.87％.Among the evaluators,1,739(22.17％)believed that there were implementation obstacles in the consensus.Conclusion The clinical applicability of the consensus is relatively good,and the application of the consensus helps to improve the standardization of clinical operations.In the future,efforts should be made to strengthen the promotion and training of the consensus,develop hierarchical promotion strategies according to the characteristics of medical institutions,and improve the quality of evidence for the consensus,so as to further enhance the clinical application effect of the consensus.

Objective:To compare the efficacy of O-arm navigation-assisted and freehand posterior pedicle screw fixation in the treatment of ankylosing spondylitis (AS) associated with lower cervical fractures in adults.Methods:A retrospective cohort study was conducted to analyze the clinical data of 29 adult AS patients with lower cervical fractures admitted to Zhengzhou Orthopedic Hospital from June 2020 to September 2024, including 22 males and 7 females, aged 35-72 years [(52.3±11.1)years]. Injured segments involved C 5~6 in 6 patients, C 6 in 8, C 6~7 in 8, and C 7 in 7. Accirdubg to AO classification, the fracture was classified as type B3 in 22 patients and type C in 7. All the patients underwent posterior cervical pedicle screw fixation, among whom 15 patients were treated with navigation-assisted screw placement (navigation screw placement group, with 120 screws) and 14 with freehand technique (freehand screw placement group, with 112 screws). The two groups were compared in terms of the operative time, intraoperative blood loss, and postoperative drainage volume. The accuracy of screw placement, penetration rate of the pedicle cortex and fracture healing time were evaluated in the two groups. The Cobb angle before surgery and at 3 days after surgery and American Spinal Injury Association (ASIA) classification before surgery and at the last follow-up were recorded in the two groups. The visual analogue scale (VAS) score, Japanese Orthopedic Association (JOA) score and neck dysfunction index (NDI) before surgery, at 1 week, 3 months after surgery and at the last follow-up were compared between the two groups. The incidence of postoperative complications was also investigated. Results:All the patients were followed up for 6-57 months [(29.3±14.1)months]. The operation duration, intraoperative blood loss, and postoperative drainage volume were (166.0±31.4)minutes, (256.7±70.7)ml, and (91.0±14.4)ml in the navigation screw placement group, which were shorter or less than (219.29±31.7)minutes, (342.1±60.7)ml, and (123.2±20.7)ml in the freehand screw placement group ( P<0.01). The accuracy of screw placement in the navigation screw placement group was 98.3% (118/120) and penetration rate of the pedicle cortex was 5.8% (7/120), which were both superior to 89.3% (100/112) and 18.8% (21/112) in the freehand screw placement group ( P<0.01). No significant difference was detected in fracture healing time between the two groups ( P>0.05). There were no significant differences in the Cobb angle before surgery and at 3 days after surgery, as well as in the ASIA grading before surgery and at the last follow-up between the two groups ( P>0.05). The Cobb angle and ASIA classification at 3 days after surgery and at the last follow-up were improved compared with those before surgery ( P<0.05). Before surgery, at 1 week, 3 months after surgery, and at the last follow-up, the VAS scores were 8.0(7.0, 9.0)points, 4.0(3.0, 4.0)points, 2.0(1.0, 2.0)points, and 0.0(0.0, 1.0)points in the navigation screw placement group, which were not significantly different from 8.0(7.0, 9.0)points, 4.0(3.0, 4.0)points, 1.5(1.0, 2.0)points, and 0.0(0.0, 1.0)points in the freehand screw placement group ( P>0.05); the JOA scores were (7.5±1.4)points, (10.9±1.2)points, (13.2±1.5)points, and (15.7±1.0)points in the navigation screw placement group, which were not significantly different from (7.2±2.8)points, (10.1±3.2)points, (11.8±3.8)points, and (14.1±4.3)points in the freehand screw placement group ( P>0.05); the NDI were 48.0(44.0, 56.0)%, 30.0(30.0, 34.0)%, 18.0(16.0, 22.0)%, 8.0(6.0, 10.0)% in the navigation screw placement group, which were not significantly different from 44.0(40.0, 52.0)%, 30.0(29.0, 34.5)%, 17.0(16.0, 20.0)%, and 8.0(5.5, 10.0)% in the freehand screw placement group ( P>0.05). The VAS scores, JOA scores, and NDI were improved at 1 week, 3 months after surgery, and at the last follow-up in both groups, compared to those before surgery and they were gradually improved with the passage of the follow-up time ( P<0.05). One patient in the navigation screw placement group developed postoperative pulmonary infection and recovered after symptomatic treatment, with an incidence of complications 7% (1/15). Two patients in the freehand screw placement group had postoperative cerebrospinal fluid leakage and dural rupture and recovered after symptomatic treatment, with an incidence of complications 14% (2/14). Throughout the follow-up period, no complications such as screw breakage, implant loosening, or loss of correction were found in either group. Conclusion:Compared with freehand screw placement, the O-arm navigation system-assisted posterior pedicle screw fixation in the treatment of AS associated with lower cervical fractures in adults demonstrates significant advantages, including reduced operative time, decreased intraoperative blood loss and postoperative drainage volume, improved accuracy of screw placement, and reduced penetration rate of the pedicle cortex.

Objective:To compare the efficacy of whole-process visualization system-assisted pedicle screw internal fixation and free-hand pedicle screw internal fixation in the treatment of thoracolumbar burst fracture (TLBF) without neurologic symptoms.Methods:A retrospective cohort study was conducted to analyze the clinical data of 64 patients with TLBF without neurologic symptoms admitted to Zhengzhou Orthopedic Hospital from December 2020 to October 2022, including 41 males and 23 females, aged 23-52 years [(42.1±6.6)years]. The injured vertebrae involved T 11 in 26 patients, T 12 in 17, L 1 in 12, and L 2 in 9. The Wiltse approach was used in all the patients, 31 of whom were treated with pedicle screw internal fixation assisted by the whole-process visualization system (visualization system-assisted screw placement group) and 33 of whom were treated with free-hand pedicle screw internal fixation (free-hand screw placement group). The two groups were compared in terms of operation time, single screw placement time, intraoperative blood loss, intraoperative total radiation dose and total length of hospital stay. The accuracy of pedicle screw placement and penetration rate of the pedicle cortex were evaluated in the two groups. The Cobb angle and lumbar visual analogue scale (VAS) before surgery, at 1 week, 3 months after surgery and at the last follow-up were compared between the two groups. The incidence of postoperative complications was also investigated. Results:All the patients were followed up for 10-33 months [(17.5±4.8)months]. The operation time was (106.9±11.8)minutes in the visualization system-assisted screw placement group, shorter than (121.3±11.4)minutes in the free-hand screw placement group ( P<0.01). The single screw placement time was (9.1±1.0)minutes in the visualization system-assisted screw placement group, shorter than (11.7±1.5)minutes in the free-hand screw placement group ( P<0.01). The total radiation dose was (10.4±2.4)mGy in the visualization system-assisted screw placement group, lower than (51.8±7.2)mGy in the screw placement group ( P<0.01). There was no significant difference in intraoperative blood loss or total length of hospital stay between the two groups ( P>0.05). The accuracy of pedicle screw placement was 96.6% (197/204) in the visualization system-assisted screw placement group, significantly higher than 89.3% (191/214) in the free-hand screw placement group ( P<0.01). Both groups showed significant improvements in Cobb angle and VAS scores at 1 week, 3 months after surgery, and at the last follow-up ( P<0.05). There were no significant differences in Cobb angle or VAS scores between the two groups at each time point ( P>0.05). In the visualization system-assisted screw placement group, one patient had incision infection at 4 days after operation, which was cured with antibiotics. One patient in the free-hand screw placement group developed the symptoms of nerve root irritation at 2 days after surgery, which disappeared at 7 days after revision. There was no significant difference in the incidence of complications between the two groups ( P>0.05). During the follow-up, no patients had broken screws, loosening of internal fixation, or loss of correction in either group. Conclusions:Compared with free-hand pedicle screw internal fixation, the whole-process visualization system-assisted pedicle screw internal fixation in the treatment of TLBF without neurologic symptoms can shorten the time of operation and screw placement, reduce the radiation dose, and improve the accuracy of pedicle screw placement, suggesting that it is a safer and more effective auxiliary method for pedicle screw placement.

Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

Objective:To compare the efficacy of three-dimensional visualization-assisted intermuscular versus conventional intermuscular cervical expansive open-door laminoplasty (CEOL) in the treatment of cervical spinal cord injury without fracture or dislocation (CSCIWFD).Methods:A retrospective cohort study was conducted to analyze the clinical data of 58 patients with CSCIWFD admitted to Zhengzhou Orthopedic Hospital from October 2021 to January 2024, including 39 males and 19 females, aged 36-77 years [(52.9±8.9)years]. Among them, 26 patients were treated with three-dimensional visualization-assisted intermuscular CEOL (three-dimensional visualization group), while 32 patients were treated with conventional intermuscular CEOL (conventional intermuscular group). All patients were treated with CEOL in 4 segments (C 3-C 6), comprising 104 surgical segments in the three-dimensional visualization group and 128 in the conventional intermuscular group. The following outcomes were compared between the two groups, including the operative duration, intraoperative blood loss, accuracy rate of open-door and hinge placement at the surgical levels, visual analogue scale (VAS) of the neck and shoulder and Japanese Orthopedic Association (JOA) score preoperatively, at 1 week, 1 month, 3 months, 6 months postoperatively and at the last follow-up, American Spinal Injury Association (ASIA) impairment scale preoperatively and at the last follow-up, and postoperative complication rate. Results:All patients were followed up for 12-24 months [(17.5±3.1)months]. The operative duration and intraoperative blood loss were (117.0±12.3)minutes and (151.3±30.9)ml in the three-dimensional visualization group, which were shorter or less than (131.9±15.0)minutes and (184.7±42.9)ml in the conventional intermuscular group ( P<0.01). The accuracy rate of open-door and hinge placement at the surgical levels was 94.2% (98/104) in the three-dimensional visualization group, significantly higher than 83.6% (107/128) in the conventional intermuscular group ( P<0.05). The VAS scores of the neck and shoulder preoperatively, at 1 week, 1 month, 3 months, 6 months postoperatively, and at the last follow-up were 6.0(5.0, 7.0)points, 3.5(3.0, 4.0)points, 3.0(2.0, 3.0)points, 2.0(1.0, 3.0)points, 2.0(1.0, 2.3)points, and 2.0(1.0, 2.0)points in the three-dimensional visualization group, which were not statistically different from 5.0(4.3, 6.8)points, 4.0(3.0, 4.0)points, 3.0(2.0, 3.0)points, 2.0(1.3, 2.0)points, 2.0(1.0, 2.8)points, and 2.0(1.0, 2.0)points in the conventional intermuscular group ( P>0.05). The VAS scores of the neck and shoulder in the two groups were significantly decreased at 1 week, 1 month and 3 months postoperatively from the preoperative values ( P<0.05), while they were stabilized at 6 months postoperatively and at the last follow-up compared with those at 3 months postoperatively, with no significant difference among them ( P>0.05). The JOA scores were (8.1±2.8)points, (10.0±2.6)points, (10.5±2.6)points, (11.6±2.3)points, (12.7±2.3)points, and (13.7±2.4)points in the three-dimensional visualization group, which were not statistically different from (8.8±2.2)points, (10.3±2.1)points, (10.8±2.0)points, (12.0±2.0)points, (12.9±2.0)points, and (13.8±2.1)points in the conventional intermuscular group ( P>0.05). The JOA scores of the two groups showed continuous improvement at 1 week, 1 month, 3 months, 6 months postoperatively and at the last follow-up in comparison with the preoperatively values ( P<0.05). Although no significant difference was observed between the two groups in ASIA grade preoperatively and at the last follow-up ( P>0.05), the ASIA grade at the last follow-up was significantly improved compared with that before surgery in both groups ( P<0.05). The postoperative complication rate was 12% (3/26) in the three-dimensional visualization group, significantly lower than 38% (12/32) in the conventional intermuscular group ( P<0.05). Conclusion:Compared with the conventional intermuscular approach, the three-dimensional visualization-assisted intermuscular CEOL offers advantages in reducing surgical trauma, improving surgical precision, and lowering the postoperative complication rate in the treatment of CSCIWFD.

Objective:To explore the value of 18F-FDG PET brain imaging in the auxiliary diagnosis of autoimmune encephalitis (AE) before treatment, and to analyze the regional and course-related characteristics of brain metabolic changes. Methods:The 18F-FDG PET brain imaging data of 49 AE patients (26 males, 23 females, age 48.0(29.0, 61.0) years) who did not receive first-line immunotherapy were retrospectively analyzed. Patients were collected from Renji Hospital, Shanghai Jiao Tong University School of Medicine, between July 2015 and December 2023. Forty-nine age- and gender-matched healthy subjects who underwent routine physical examination at the same time period were selected as the healthy controls (HC). The statistical parametric mapping (SPM) 8 two-sample t test ( P<0.001, k=50) was used to compare the imaging results of AE patients with those of HC. The screening results were adjusted by the cluster-level family-wise error rate (FWER) for P<0.05. Metabolic abnormalities associated with AE were identified, and differences in metabolic patterns at different stages of the disease course (short: ≤1 month; medium: >1 month and ≤3 month; long: >3 month) were compared by subgroup analysis. Mann-Whitney U test was used to analyze the data. Results:In the included AE patients, regions with elevated metabolism were mainly located in the limbic lobe, insula, putamen, and amygdala ( t values: 3.18-5.07, Z values: 3.17-4.76), while local metabolic reduction was observed in the frontal, parietal, and occipital lobes ( t values: 3.18-5.43, Z values: 3.23-5.06), with most of these regions passing FWER correction. In patients with anti- N-methyl- D-aspartate receptor (NMDAR) encephalitis, local metabolism increased in the right superior temporal gyrus ( t values: 3.55-4.79, Z values: 3.67-3.86) and decreased in the left middle temporal gyrus and inferior frontal gyrus ( t values: 3.55-5.43, Z values: 3.45-4.21), but the results did not pass the FWER correction. Subgroup analysis showed that in patients with short disease course ( n=17), regions with locally elevated metabolism included the brainstem, limbic lobe, and cerebellum ( t values: 3.37-5.27, Z values: 3.52-4.44), while regions with reduced metabolism were mainly located in the frontal, parietal, and occipital lobes ( t values: 3.37-6.77, Z values: 3.34-5.30), and these abnormal results all passed FWER correction. In patients with medium ( n=7) to long ( n=25) disease course, the regions with metabolic abnormalities were significantly reduced and did not pass FWER correction. Conclusions:18F-FDG PET can accurately identify brain metabolic abnormalities in AE patients, demonstrating significant regional and course-related characteristics. Metabolic abnormalities are more pronounced in patients with short disease course, while they are relatively less obvious in patients with medium to long disease course.
