Background: The association of changes in metabolic syndrome (MetS) with cognitive function remains unclear. We explored this association using prospective and Mendelian randomization (MR) studies. Methods: MetS components including high-density lipoprotein cholesterol (HDL-C), systolic blood pressure (SBP), waist circumference (WC), fasting plasma glucose (FPG), and triglycerides were measured at baseline and two follow-ups, constructing a MetS index. Immediate, delayed memory recall, and cognitive function along with its dimensions were assessed by immediate 10- word recall test (IWRT) and delayed 10-word recall test (DWRT), and mini-mental state examination (MMSE), respectively, at baseline and follow-ups. Linear mixed-effect model was used. Additionally, the genome-wide association study (GWAS) of MetS was conducted and one-sample MR was performed to assess the causality between MetS and cognitive function. Results: Elevated MetS index was associated with decreasing annual change rates (decrease) in DWRT and MMSE scores, and with decreases in attention, calculation and recall dimensions. HDL-C was positively associated with an increase in DWRT scores, while SBP and FPG were negatively associated. HDL-C showed a positive association, whereas WC was negatively associated with increases in MMSE scores, including attention, calculation and recall dimensions. Interaction analysis indicated that the association of MetS index on cognitive decline was predominantly observed in low family income group. The GWAS of MetS identified some genetic variants. MR results showed a non-significant causality between MetS and decrease in DWRT, IWRT, nor MMSE scores. Conclusion Our study indicated a significant association of MetS and its components with declines in memory and cognitive function, especially in delayed memory recall.

Patients with periodontal disease often require combined periodontal-orthodontic interventions to restore periodontal health, function, and aesthetics, ensuring both patient satisfaction and long-term stability. Managing these patients involving orthodontic tooth movement can be particularly challenging due to compromised periodontal soft and hard tissues, especially in severe cases. Therefore, close collaboration between orthodontists and periodontists for comprehensive diagnosis and sequential treatment, along with diligent patient compliance throughout the entire process, is crucial for achieving favorable treatment outcomes. Moreover, long-term orthodontic retention and periodontal follow-up are essential to sustain treatment success. This expert consensus, informed by the latest clinical research and practical experience, addresses clinical considerations for orthodontic treatment of periodontal patients, delineating indications, objectives, procedures, and principles with the aim of providing clear and practical guidance for clinical practitioners.

Objective To analyze the independent risk factors affecting complications of preoperative CT-guided Hookwire localization of pulmonary nodules, and establish and validate a nomogram risk prediction model. Methods Clinical data of patients who underwent thoracoscopic lung surgery with preoperative CT-guided Hookwire localization at the Department of Thoracic Surgery, Affiliated Nanjing Brain Hospital, Nanjing Medical University from January 2023 to October 2023 were collected. Patients were divided into a complication group and a non-complication group according to whether they had complications. The clinical data of the two groups were compared by univariate analysis and multivariate binary logistic regression analysis to determine the independent risk factors causing complications during localization, and a nomogram prediction model was established. The discrimination of the model was evaluated by receiver operating characteristic (ROC) curve, and the consistency between predicted events and actual results was evaluated by calibration curve. Results A total of 300 patients were included, including 143 males and 157 females, aged 24-68 (46.00±22.81) years. Univariate analysis showed that there were statistically significant differences in age, number and location of nodules, preoperative anxiety score, history of chronic obstructive pulmonary disease (COPD), number of needle adjustments, pain score, and distance between the tip of the localization needle and the visceral pleura between the two groups (P<0.05). Multivariate binary logistic regression analysis suggested that pain score [OR=1.253, 95%CI (1.094, 1.434), P=0.001], age [OR=1.020, 95%CI (1.000, 1.042), P=0.049], history of COPD [OR=3.281, 95%CI (1.751, 6.146), P<0.001], number of nodules [OR=1.667, 95%CI (1.221, 2.274), P=0.001], preoperative anxiety score [OR=1.061, 95%CI (1.031, 1.092), P<0.001], number of needle adjustments [OR=1.832, 95%CI (1.263, 2.658), P=0.001], and distance between the needle tip and the visceral pleura [OR=1.759, 95%CI (1.373, 2.254), P<0.001] were associated with localization complications. The area under the ROC curve for the modeling group was 0.825, and that for the validation group was 0.845. Hosmer-Lemeshow test showed that there was no statistically significant difference between the ideal curve of the model fitting curve and that of the modeling group and internal validation group, indicating good goodness of fit (χ2=6.488, P=0.593). Conclusion Advanced age, multiple nodules, preoperative anxiety, history of COPD, multiple needle adjustments, severe pain during localization, and long distance between the tip of the localization needle and the visceral pleura are independent risk factors for complications of lung nodule localization, and the prediction model based on these factors has good predictive performance.

BACKGROUND: Disease-modifying therapies have been approved for the treatment of relapsing multiple sclerosis (RMS). The present study aims to examine the safety of teriflunomide in Chinese patients with RMS. METHODS: This non-randomized, multi-center, 24-week, prospective study enrolled RMS patients with variant (c.421C>A) or wild type ABCG2 who received once-daily oral teriflunomide 14 mg. The primary endpoint was the relationship between ABCG2 polymorphisms and teriflunomide exposure over 24 weeks. Safety was assessed over the 24-week treatment with teriflunomide. RESULTS: Eighty-two patients were assigned to variant ( n  = 42) and wild type groups ( n  = 40), respectively. Geometric mean and geometric standard deviation (SD) of pre-dose concentration (variant, 54.9 [38.0] μg/mL; wild type, 49.1 [32.0] μg/mL) and area under plasma concentration-time curve over a dosing interval (AUC tau ) (variant, 1731.3 [769.0] μg∙h/mL; wild type, 1564.5 [1053.0] μg∙h/mL) values at steady state were approximately similar between the two groups. Safety profile was similar and well tolerated across variant and wild type groups in terms of rates of treatment emergent adverse events (TEAE), treatment-related TEAE, grade ≥3 TEAE, and serious adverse events (AEs). No new specific safety concerns or deaths were reported in the study. CONCLUSION: ABCG2 polymorphisms did not affect the steady-state exposure of teriflunomide, suggesting a similar efficacy and safety profile between variant and wild type RMS patients.

Objective To evaluate the safety and efficacy of basic anesthesia combined with local anesthesia in the preoperative localization of multiple pulmonary nodules. Methods The clinical data of patients who underwent preoperative localization for multiple pulmonary nodules resection under single-port thoracoscopy in Nanjing Brain Hospital from July 2023 to September 2023 were extracted. They were divided into a group A and a group B according to the localization method. The patients in the group A were localized under local anesthesia, and the patients in the group B were localized with basic anesthesia combined with local anesthesia. The basic clinical characteristics, localization success rate, incidence of localization complications, localization time, and pain score of the two groups were compared and analyzed. Results Finally, we included 200 patients with 100 patients in each group. There were 49 males and 51 females at age of 25-77 (50.94±14.29) years in the group A. There are 45 males and 55 females at age of 24-78 (48.25±14.04) years in the group B. The incidence of localization complications (4% vs. 13%, P=0.04), localization time [(19.90±8.66) min vs. (15.23±5.98) min, P<0.01], and pain score[ (2.01±2.09) vs. (3.29±2.54), P<0.01] in the group B were significantly lower than those in the group A, and the differences were statistically significant. The localization success rate of the group B was significantly higher than that of the group A (98% vs. 92%, P=0.04), and the difference was statistically significant.Conclusion Mobile CT combined with basic anesthesia for preoperative localization of multiple pulmonary nodules is highly safe, has a high success rate, and provides high patient comfort, making it a valuable approach for clinical promotion.

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.

C-Reactive protein(CRP)is an important acute-phase response protein,which is widely used in the assessment of inflammation and cardiovascular disease risk,and acts as a pathogenic factor directly involved in the disease process of certain conditions.Therefore,developing immunosuppressants targeting CRP or investigating its pathogenic mechanisms is of significant importance.Most B-cell epitopes are conformational epitopes,and studying conformational epitopes is typically challenging.To date,no methods have been reported for mapping the conformational epitopes of CRP in solution.In this study,a rapid strategy was developed for studying conformational epitopes by combining hydrogen/deuterium exchange mass spectrometry(HDX-MS)with multiparametric prediction of B-cell epitopes and protein secondary structure analysis.This approach was successfully applied to the binding sites and allosteric targets of the 115 kDa full pentameric CRP and the clinically used monoclonal antibody(mAb)5A8.The results showed that the amino acid residues 84-103,138-146,and 165-173 together form the potential conformational epitopes for mAb 5A8 on CRP,while the amino acid residues 21-32 and 175-178 were identified as potential allosteric targets.The discovery of the mAb 5A8 binding sites and allosteric targets was crucial for improving clinical diagnostic capabilities.Experimental results demonstrated that this workflow allowed rapid conformational epitope mapping of CRP under near-physiological conditions,with advantages such as high speed,high sensitivity,and high throughput.
