ObjectiveTo evaluate the comparative clinical outcomes of zero-profile interbody fusion （Zero-P） and traditional anterior cervical discectomy and fusion with titanium plate （ACDF-plate） for three-level cervical spondylosis， providing a reference to optimize surgical strategies for three-level cervical spondylosis. MethodsIn this retrospective comparative study， 113 patients were included and assigned to either the Zero-P group （n=51） or the ACDF-plate group （n=62） according to their surgical approaches. Clinical outcomes were evaluated and compared between the two groups using operative time， intraoperative blood loss， length of hospital stay， visual analog scale （VAS） scores， cervical range of motion （ROM）， neck disability index （NDI）， Cervical Disability Index （CDI）， Japanese orthopaedic association （JOA） scores， and postoperative complication rates. ResultsCompared with the ACDF-plate group， the Zero-P group had a shorter operative time and less intraoperative blood loss （P<0.05）； the neck pain VAS score was lower on the 1st day and 1st week after surgery （P<0.05）； the cervical flexion range of motion was higher at 1 month after surgery （P<0.05）； the JOA score was higher at 3 months after surgery， while the NDI and CDI scores were lower （P<0.05）； the total incidence of complications （11.76%） was significantly lower than that in the plate fixation group （35.48%）， and the incidence of neck foreign body sensation/stiffness was lower （P<0.05）. ConclusionZero-P not only demonstrates safety and efficacy comparable to the ACDF-plate， but also highlights the significant value of the minimally invasive concept in facilitating early recovery. Both procedures have their respective emphasis on biomechanical maintenance and minimally invasive benefits， providing a clear evidence-based reference for individualized and precise surgical decision-making in three-level cervical spondylosis.

Objective:To evaluate the perioperative application effect of enhanced recovery after surgery (ERAS) clinical pathway in percutaneous vertebro plasty (PVP).Methods:The clinical data of 274 patients who underwent PVP treatment for osteoporotic vertebral compression fracture (OVCF) in Beijing Friendship Hospital, Capital Medical University from May 2023 to August 2024 were retrospectively analyzed. The patients were divided into two groups according to the different numbers of surgical segments: the single-segment group ( n=211) and the multisegment group ( n=63). Patients in the single-segment group underwent single-segment surgery, while patients in the multisegment group underwent surgery on ≥2 segments. The core points of the ERAS clinical pathway adopted in this study include perioperative education, pain management, early mobilization, application of "outfast", and joint guidance from the departments of nutrition and rehabilitation. Comparison was made between the two groups of patients in terms of visual analog scale (VAS) scores for low back pain at preoperative, 2 h, 6 h, 24 h postoperatively, and on the day of discharge; Oswestry disability index (ODI) scores preoperatively and on the day of discharge; time to first ambulation postoperatively, total length of hospital stay, postoperative length of stay, perioperative complications, and perioperative application of Opioid consumption. Measurement data were expressed as mean±standard deviation ( ± s), and the independent sample t-test was used for comparison between groups; count data were expressed as cases and percentage, and the Chi-square test was used for comparison between groups. The VAS pain scores at each stage of the perioperative period were evaluated using repeated measures analysis of variance or generalized estimating equations. Results:Compared with that before the operation [(6.17±0.93) points, (6.29±0.83) points], the VAS scores of low back pain of patients in the single-segment group and the multisegment group at 2 hours after surgery [(3.09±0.82) points, (3.27±0.65) points], 6 hours after surgery [(2.60±0.79) points, (2.62±0.55) points], and 24 hours after surgery [(1.89±0.77) points, (1.97±0.72) points] and on the day of discharge [(1.72±0.71) points, (1.81±0.64) points] were significantly decreased, and the differences were statistically significant ( P<0.05). At the same stage, the VAS scores of low back pain in both groups were not statistically significant ( P>0.05). The ODI scores of patients in the single-segment group and the multisegment group on the day of discharge [(24.21±2.35) points, (24.63±3.31) points] were significantly lower than those before the operation [(64.50±4.81) points, (65.52±4.08) points], and the differences were statistically significant ( P<0.05). There were no statistically significant differences in perioperative complications and the proportion of Opioid drug application between the two groups of patients ( P>0.05). Conclusion:For patients with single-segment or multisegment OVCF, PVP surgical treatment under ERAS clinical pathway management can achieve immediate pain relief, early ambulation exercise, and satisfactory perioperative efficacy.

Objective:To evaluate preoperative malnutrition risk in patients with osteoporotic vertebral compression fracture (OVCF) based on mini nutritional assessment short form (MNA-SF) and analyze the related clinical risk factors.Methods:A cross-sectional study was conducted using clinical data from 129 OVCF patients who underwent percutaneous vertebroplasty at Beijing Friendship Hospital, Capital Medical University, between May 2023 and December 2023. The cohort included 26 males and 103 females, aged (74.71±9.13) years(ranging from 48-98 years). According to MNA-SF scoring method, they were divided into three groups, the malnutrition group ( n=6), the nutritional risk group ( n=40), and the good nutrition group ( n=83). Nutritional risk and malnutrition rates were evaluated using the MNA-SF score. Measurement data with normal distribution were expressed as mean±standard deviation ( ± s) and compared using one-way ANOVA. The comparison between groups of count data was conducted using chi-square test. Univariate analysis and multivariate logistic regression were performed to identify independent risk factors for malnutrition and nutritional risk. Results:According to the MNA-SF score, among 129 patients, the malnutrition rate was 4.7%, the nutritional risk rate was 31.0%, and 64.3% exhibited adequate nutrition based on MNA-SF scores. The results of one-way ANOVA showed that gender ( P=0.023) and BMI ( P<0.001) were significantly correlated with malnutrition and nutritional risk; Logistic regression analysis suggested that the influencing factors of nutritional risk included gender ( P=0.002) and BMI ( P<0.001), while the only dangerous factor of malnutrition was BMI ( P<0.001). Conclusions:Bsed on MNA-SF, OVCF patients undergoing percutaneous vertebroplasty have a higher incidence of malnutrition and nutritional risk. The risk factors for nutritional risk in patients are gender and BMI, while the risk factor for malnutrition is only BMI.

Objective:To explore the risk factors of cement leakage into the spinal canal in percutaneous vertebroplasty (PVP) for spinal metastases.Methods:A retrospective analysis was conducted on the case data of 211 patients with spinal metastases who underwent PVP in the Department of Orthopaedics, Beijing Friendship Hospital, Capital Medical University from January 2016 to June 2024. According to the presence or absence of intraspinal bone cement leakage after surgery, the patients were divided into the leakage group ( n=45) and the non-leakage group ( n=166). The clinical data of the two groups, including gender, age, bone mineral density T-score, American Society of Anesthesiologists (ASA) classification, operation time, and bone cement injection volume, were collected and statistically analyzed. Measurement data were expressed as mean±standard deviation ( ± s), and the independent samples t-test was used for comparison between groups; count data were expressed as the number of cases and percentage, and the Chi-square test was used for comparison between groups. Univariate analysis was used to explore the possible risk factors for intraspinal bone cement leakage after PVP, and then the indicators with statistically significant differences in the univariate analysis were included in the multivariate Logistic regression analysis to identify the independent risk factors. Results:A total of 45 patients out of 211 patients with PVP surgery had cement leakage into the spinal canal after surgery, with an incidence rate of 21.3%. There were statistically significant differences between the leakage group and the non-leakage group in terms of whether the posterior wall of the vertebral body was broken, operation time, the injection volume of bone cement, distribution of injured vertebrae, and viscosity of bone cement ( P<0.05). The results of multivariate Logistic regression analysis showed that the broken posterior wall of the vertebral body, large injection volume of bone cement, and low viscosity of bone cement were the independent risk factors for the occurrence of cement leakage into the spinal canal in PVP for spinal metastases ( P<0.05). Conclusion:When PVP surgery is used to treat spinal metastases, broken posterior wall of the vertebral body, large injection volume of bone cement, and low viscosity of bone cement can increase the incidence of postoperative intravertebral cement leakage, and the operation should be performed with caution.

Objective:To explore how one-sided/two-sided brain blood flow affects the occurrence of neurological complications in patients with Stanford type A aortic dissection, as well as to assess the factors that contribute to the development of neurological complications.Methods:A total of 162 patients diagnosed with Stanford type A aortic dissection who had undergone ascending aorta and total aortic arch replacement at Affiliated Hospital of Jining Medical College from August 2020 to December 2023 were retrospectively reviewed. These patients were categorized into two groups based on the presence of postoperative neurological complications: a group with neurological complications comprising 77 cases and a group without neurological complications comprising 85 cases. A comparative analysis was carried out on general clinical data, surgical and brain perfusion characteristics, as well as preoperative test indicators between these two groups in order to investigate the factors influencing the occurrence of postoperative neurological complications in patients with Stanford type A aortic dissection. The data was analyzed using Logistic regression to identify the risk factors associated with postoperative neurological complications and to develop a predictive nomogram model. Calibration curves, receiver operating characteristic (ROC) curves and decision curve (DCA) were generated to assess the accuracy and predictive capability of the nomogram model.Results:In the group of patients who experienced neurological complications, there was a higher prevalence of a history of hypertension, longer operation time, extended periods of cardiopulmonary bypass, cross-clamping, brain perfusion, cooling, and rewarming, as well as increased postoperative drainage volume. Additionally, the levels of preoperative blood urea nitrogen (BUN), creatinine (Cr) and lactic acid (Lac) were elevated compared to those in the non-neurological complications group: 77.9% (60/77) vs. 52.9% (45/85), (409.99 ± 104.26) min vs. (348.29 ± 63.12) min, (223.36 ± 66.86) min vs. (179.25 ± 38.59) min, 112 (94, 133) min vs. 96 (84, 113) min, (35.23 ± 9.89) min vs. (32.14 ± 6.81) min, (82.19 ± 28.69) min vs. (68.76 ± 29.06) min, (79.30 ± 22.60) min vs. (69.54 ± 16.42) min, 806 (529, 1 127) ml vs. 663 (449, 925) ml, 6.78 (5.38, 8.84) mmol/L vs. 6.08 (4.66, 7.76) mmol/L, 86.3 (64.0, 131.9) μmol/L vs. 71.0 (55.6, 84.9) μmol/L, 2.1(1.2, 4.0) mmol/L vs. 1.5 (0.9, 2.3) mmol/L. On the other hand, the percentage of patients who underwent bilateral brain perfusion was lower, and they experienced lower lowest temperature, preoperative platelet count, and ejection fraction levels than those in the non-neurological complications group: 57.1% (44/77) vs. 75.3% (64/85), (25.69 ± 1.04) ℃ vs. (26.04 ± 0.82) ℃, (175.79 ± 58.14) ×10 9/L vs. (213.87 ± 77.29) ×10 9/L, (54.18 ± 3.84)% vs. (55.34 ± 3.56)% ( P<0.05). Multivariate Logistic regression analysis revealed that a prior history of high blood pressure, prolonged cardiopulmonary bypass duration were identified as autonomous risk factors for the development of postoperative neurological issues in individuals with Stanford type A aortic dissection, while simultaneous brain perfusion emerged as an independent protective element ( P<0.05). Subsequently, a predictive nomogram was constructed incorporating these three pivotal factors to assess the likelihood of postoperative neurological complications in patients with Stanford type A aortic dissection. The calibration curve exhibited a noteworthy level of accuracy for the nomogram predictive model ( χ2 = 9.01, P = 0.342). Additionally, the ROC curve analysis displayed an area under the curve of 0.84 (95% CI 0.78 to 0.90) for the nomogram model in predicting postoperative neurological complications in patients with Stanford type A aortic dissection, indicating a high predictive accuracy. Moreover, DCA analysis indicated that the nomogram model provided a net benefit above 0 across the spectrum of 0 to 90%. Conclusions:Postoperative neurological complications in patients with Stanford type A aortic dissection is linked to factors such as a previous history of hypertension, unilateral brain perfusion, an extended cardiopulmonary bypass duration. By developing a nomogram model that incorporates these factors, it becomes feasible to accurately forecast the likelihood of postoperative neurological complications in this patient population. This predictive tool holds significant value in facilitating proactive clinical risk evaluation and preventive measures.

Background::The increasing incidence of inflammatory bowel disease (IBD) presents significant medical and societal challenges. A well-designed IBD database is crucial for both epidemiological studies and clinical management. However, inconsistencies between regional databases hinder cross-institutional and international research, especially between Eastern and Western societies.Methods::We developed a new IBD database, the 301 IBD database, integrating the IBD clinical characteristics from the Penn IBD database (USA) and the latest IBD guidelines and consensus and clinical practices of the Chinese PLA General Hospital (PLAGH). We applied this database to analyze clinical data of IBD inpatients at PLAGH from 2008 to 2023.Results::The 301 IBD database contains 490 items in 6 sections including demographic characteristics, personal history, clinical phenotype, disease activity, laboratory tests and examinations, and treatment. Features of the 301 IBD database include inpatient focus, biochemical indicators and opportunistic infection focus, and more about ulcerative colitis (UC)-associated complications. Single-center analysis revealed an increasing hospitalization trend, from 2.35% in 2008 to 3.94% in 2023. We found that the clinical characteristics of our UC inpatients are predominantly male (62.5%), extensive lesions (55.1%), low usage of biologics (4.1%), and a high incidence of UC-CRC (3.0%). The clinical characteristics of CD inpatients included male predominance (68.39%), early onset age (35.43 ± 14.75-year-old), and high rate of surgery (25.81%).Conclusion::The 301 IBD database, integrating Eastern and Western clinical data, provides a valuable tool for IBD clinical research. Future international, multicenter collaborations are expected to further enhance its utility.
