Objective To analyze the effect of releasing the lower pulmonary ligament on right residual lung expansion after right upper lobe resection under different body mass index (BMI) levels. Methods The clinical data of patients who underwent thoracoscopic right upper lobe resection in the First Affiliated Hospital with Nanjing Medical University from 2021 to 2022 were retrospectively analyzed. Patients were divided into a group A (17 kg/m2＜BMI≤23 kg/m2), a group B (23 kg/m2＜BMI≤29 kg/m2) and a group C (BMI＞29 kg/m2) according to BMI. The presence of residual cavity was judged by chest X-ray at 7-10 days after operation, the degree of compensation change of the right main bronchus angle was measured, and the changes in lung volume were determined by CT three-dimensional reconstruction. Results A total of 157 patients who underwent thoracoscopic right upper lobe resection were included, including 71 males and 86 females, with an average age of (59.7±11.2) years. There were 50 patients in the group A, 75 patients in the group B, and 32 patients in the group C. In the group A, compared with those without releasing the lower pulmonary ligament, patients with releasing had a lower incidence of postoperative residual cavity (P=0.016), greater changes in bronchus angle (P<0.001), and smaller changes in lung volume (P<0.001). In the group B and C, there was no significant effect of releasing the lower pulmonary ligament on postoperative residual cavity, bronchus angle, and lung volume changes (P>0.05). Conclusion For patients with thin and long body shape and low BMI, releasing the lower pulmonary ligament is helpful to promote the expansion of the residual lung after right upper lobe resection and reduce the occurrence of postoperative residual cavity in patients.

Background: and Purpose Live cell-based assays (LCBA) are increasingly used for serological antibody detection due to their ability to preserve antigen conformation, offering moderately higher sensitivity than fixed cell-based assays. However, the clinical necessity of prioritizing LCBA for the detection of aquaporin-4 immunoglobulin G (AQP4-IgG) in neuromyelitis optica spectrum disorder (NMOSD) remains unclear, especially when compared to its established role in diagnosing myelin oligodendrocyte glycoprotein antibody-associated disease. Methods: We compared the performance of live cell-based assays using immunofluorescence (LCBA-IF) and fixed cell-based assays using immunofluorescence (FCBA-IF) in detecting AQP4-IgG in 90 cases of NMOSD meeting 2015 International Panel for Neuromyelitis Optica Diagnosis criteria, alongside 40 controls. Additionally, we further investigated the relationship between AQP4-IgG titers as measured by LCBA-IF and FCBA-IF and clinical parameters in NMOSD patients. Results: Results showed 96.9% agreement between LCBA-IF and FCBA-IF (Cohen’s κ=0.935), with a strong Spearman correlation (0.977, p<0.001). Both methods demonstrated 100% specificity, with LCBA-IF showing slightly higher sensitivity compared to FCBA-IF. Within LCBAIF-tested groups, statistically significant differences in annualized relapse rates were observed across all pairwise comparisons (low-titer vs. moderate-titer, low-titer vs. high-titer, and moderate-titer vs. high-titer; all p<0.050). However, this association reached statistical significance in some FCBA-IF-tested groups. Conclusions Overall, there is a strong concordance between LCBA-IF and FCBA-IF in detecting AQP4-IgG, where LCBA-IF shows slightly higher sensitivity. Furthermore, there is a potential link between elevated AQP4-IgG titers and an increased risk of relapse, and this correlation may appear more pronounced when using LCBA-IF.

Objective:To explore latent class of symptoms related to psychological trauma and characteristics in patients with pregnancy loss, and to analyze the related influencing factors.Methods:From July 2022 to June 2024, a convenience sampling method was used to select 709 cases of pregnancy loss patients who visited the Maternity Department of the First Affiliated Hospital of Zhengzhou University as the survey subjects. The survey was conducted using the general information questionnaire, the post-traumatic stress disorder (PTSD) self-assessment scale, the hospital anxiety and depression scale, and the pittsburgh sleep index scale. Exploratory latent class analysis (LCA) of symptoms related to psychological trauma was performed by Mplus8.3, and then multivariate logistic regression was used to identify the factors influencing the latent classes.Results:A total of 691 patients with pregnancy loss were eventually investigated, with a total PTSD score of 24.00 (19.00, 33.00), a total anxiety score of 6.00 (3.00, 9.00), a total depression score of 6.00 (3.00, 9.00), and a total sleep disorder score of 7.00 (4.00, 9.00). Symptoms related to psychological trauma could be classified into 3 potential categories named high symptom group [20.4% (141/691)], anxiety-depression group [15.3% (106/691)] and low symptom group [64.3% (444/691)]. The result of multivariate logistic regression analysis showed that per capita monthly household income >8 000 yuan ( OR=0.477, 95% CI: 0.272-0.835, P=0.010) and having a spouse accompanying the patient at the time of admission ( OR=0.352, 95% CI: 0.234-0.532, P<0.001) were protective factors for the high symptom group, and gestational week≥28 weeks ( OR=3.192, 95% CI: 1.619-6.292, P=0.001) and assisted reproductive pregnancy ( OR=1.877, 95% CI: 1.075-3.277, P=0.027) were risk factors for the high symptom group. Conclusion:Symptoms associated with psychological trauma in patients with pregnancy loss have distinct categorical characteristics, and healthcare professionals should focus on patients with pregnancy loss in the high symptom group during hospitalization, and adopt targeted interventions according to the symptoms related to psychological trauma in different categories of patients with pregnancy loss in order to avoid serious psychological problems.

The extracellular matrix is an important component of articular cartilage,and in previous stud-ies it was more commonly recognized as a scaffolding structure supporting chondrocytes that provides protection from mechanical loading and elastic compression.As research continues to progress,a large body of literature sug-gests that the extracellular matrix is dynamic in nature.It degrades,deposits,and releases components in response to changes in its local microenvironment,which in turn dynamically regulates chondrocyte function and fate.There-fore,this review outlines the impact of matrix-chondrocyte interactions on chondrocyte behavior and joint homeosta-sis in osteoarthritis.It is hoped that the systematic elucidation of matrix-cell reciprocal relationships will provide new insights into the pathological mechanisms of osteoarthritis and the design and construction of cartilage tissue engineering.Specifically,we first summarize the typical molecular components that make up the extracellular matrix and the mechanical properties they confer in the matrix and the mechanotransduction functions they exert in chondrocytes.Next,we discuss the negative impact of chondrocytes on the synthesis and breakdown of matrix com-ponents during the osteoarthritic process in response to abnormal mechanical loading in the local microenvironment or disturbance by trauma.Finally,we focus on the impact of an abnormally remodeled extracellular matrix on chon-drocyte signaling and the pathological progression of osteoarthritis by mediating the generation of bioactive catabolic fragments,modulating cytokine release,and altering mechanical properties.

Objective:To explore the application effect of ADDIE model (analysis, design, development, implementation and evaluation) in the training of maxillofacial trauma first-aid ability of dental nurses, in order to optimize the training process of dental nurses.Methods:A self-controlled before and after study was conducted. Fifty-one dental nurses in Qingdao Stomatology Hospital Affiliated to Qingda University were selected as the research objects by convenient sampling method in March 2022, and the first aid ability training for maxillofacial trauma was carried out according to the five stages of ADDIE model. Before and after the training, the evaluation was made from three aspects: theory and skill test results, first-aid ability and training satisfaction scores.Results:Among 51 dental nurses, there were 4 males and 47 females, aged (30.69 ± 5.85) years. After the training, the theoretical assessment score of dental nursing staff was (88.87 ± 6.20) points, higher than that before the training (80.51 ± 7.21) points, and the technical assessment score was (91.61 ± 4.08) points, higher than that before the training (82.03 ± 7.56) points. The differences were statistically significant ( t = - 14.38, - 10.93, both P<0.01). The total score of first aid ability of nurses was (137.38 ± 11.30) points, higher than that before training (123.40 ± 13.73) points, and the difference was statistically significant ( t = - 17.30, P<0.01). The satisfaction score of dental nursing staff was (4.58 ± 0.50) points, higher than that before training (3.96 ± 0.46) points, and the difference was statistically significant ( t = - 11.51, P<0.01). Conclusions:The training program based on ADDIE model, through systematic teaching design, is helpful to improve the emergency treatment ability and training satisfaction of dental nursing staff with maxillofacial trauma.

Objective To investigate the feasibility and safety of bedside transesophageal echocardiography(TEE)-guided atrial septostomy in patients undergoing extracorporeal membrane oxygenation(ECMO)support.Methods Eight patients(2 females and 6 males)who developed pulmonary edema during VA-ECMO treatment between January 2020 and October 2024 were enrolled.All patients underwent bedside TEE-guided atrial septal puncture,followed by gradual balloon dilation using an Inoue balloon(diameter:18-24 mm).The endpoint for dilation was defined as mean left atrial pressure＜15 mmHg.Post-procedure evaluation included assessment of the septal defect size,mean left atrial pressure,and improvement in bilateral pulmonary edema.Results The mean age of all 8 patients was(43.50±16.84)years old.Atrial septostomy was successfully performed in all patients.The mean balloon dilation diameter was(22.75±2.68)mm,resulting in a mean septal defect size of(6.31±0.37)mm.The mean left atrial pressure significantly decreased from(26.63±1.77)mmHg pre-procedure to(12.75±1.28)mmHg post-procedure(P＜0.001).All patients demonstrated marked improvement in bilateral pulmonary edema,and six patients also showed a significant reduction in the severity of mitral regurgitation following the procedure.No procedure-related complications were observed.Conclusions Bedside TEE-guided atrial septostomy is safe and effective for reducing left heart loading during ECMO support and improving pulmonary edema.

Objective To investigate the distribution and antimicrobial resistance profiles of clinically isolated Haemophilus influenzae and Moraxella catarrhalis in hospitals across China from 2015 to 2021,and provide evidence for rational use of antimicrobial agents.Methods Data of H.influenzae and M.catarrhalis strains isolated from 2015 to 2021 in CHINET program were collected for analysis,and antimicrobial susceptibility testing was performed by disc diffusion method or automated systems according to the uniform protocol of CHINET.The results were interpreted according to the CLSI breakpoints in 2022.Beta-lactamases was detected by using nitrocefin disk.Results From 2015 to 2021,a total of 43 642 strains of Haemophilus species were isolated,accounting for 2.91％of the total clinical isolates and 4.07％of Gram-negative bacteria in CHINET program.Among the 40 437 strains of H.influenzae,66.89％were isolated from children and 33.11％were isolated from adults.More than 90％of the H.influenzae strains were isolated from respiratory tract specimens.The prevalence of β-lactamase was 53.79％in H.influenzae strains.The H.influenzae strains isolated from children showed higher resistance rate than the strains isolated from adults.Overall,779 strains of H.influenzae did not produce β-lactamase but were resistant to ampicillin(BLNAR).Beta-lactamase-producing strains showed significantly higher resistance rates to these antimicrobial agents than the β-lactamase-nonproducing strains.Of the 16 191 M.catarrhalis strains,80.06％were isolated from children and 19.94％isolated from adults.M.catarrhalis strains were mostly susceptible to both amoxicillin-clavulanic acid and cefuroxime,evidenced by resistance rate lower than 2.0％.Conclusions The emergence of antibiotic-resistant H.influenzae due to β-lactamase production poses a challenge for clinical anti-infective treatment.Therefore,it is very important to implement antibiotic resistance surveillance for H.influenzae and guide rational antibiotic use.All local clinical microbiology laboratories should actively improve antibiotic susceptibility testing and strengthen antibiotic resistance surveillance for H.influenzae.

Non-alcoholic fatty liver disease (NAFLD) has emerged as one of the most prevalent chronic liver diseases worldwide, with its nomenclature undergoing several stages of evolution.The three major term transitions from NAFLD to metabolic dysfunction-associated fatty liver disease (MAFLD) and subsequently metabolic dysfunction-associated steatotic liver disease (MASLD) have attracted extensive attention and discussion, presenting unprecedented opportunities and challenges.In this article, the historical development of terminology in the field of pediatric fatty liver disease was reviewed and a comparative analysis of the three primary terms (NAFLD, MAFLD, and MASLD) was conducted.By an exploration of these term changes and their implications for clinical practice, this review aims to offer valuable insights for researchers and clinicians.

OBJECTIVE: To investigate the clinical characteristics and prognosis of patients with IgD multiple myeloma (MM). METHODS: The clinical data of 8 patients with IgD MM admitted to Gansu Provincial Hospital from September 2013 to February 2023 were collected, and their clinical characteristics and prognosis were retrospectively analyzed and summarized. RESULTS: Among the 8 enrolled patients, there were 4 males and 4 females, with a median age of 60 (44-74) years. All patients had symptoms of renal insufficiency and anemia. There were 3 cases of bone invasion, 3 cases of splenomegaly, 7 cases of IgD-λ type, and 1 case of IgD-κ type. FISH examination was performed in 7 cases, and 6 of them were positive for 1q21 . There were 6 cases in DS stage III and 2 cases in DS stage II; According to ISS staging, there were 6 cases in stage III, 1 case in stage II, and 1 case in stage I; According to R-ISS staging, there were 5 cases in stage III and 3 cases in stage II. All patients received bortezomib-based combination chemotherapy, with 1 case undergoing autologous stem cell transplantation (ASCT) and 2 cases receiving daratumumab in combination. The median treatment period was 6 (1-15) cycles. The short-term efficacy was evaluated after 4-6 courses of treatment. Among the 6 patients with assessable efficacy, 1 case experienced disease progression (PD), and 5 cases achieved complete remission (CR). The median follow-up time was 26 (11-33) months, and the median progression-free survival (PFS) and median overall survival (OS) of the patients were 11.25 (3-26) months and 18.5 (4-33) months, respectively. Among the 8 patients, 4 cases died. Among the deceased patients, 3 cases were in R-ISS stage III and 3 cases were 1q21 positive. 2 of the 5 patients with early CR died due to disease progression. CONCLUSION The incidence of IgD MM is low, the symptoms of early renal damage, blood system damage and bone erosion in IgD MM patients are obvious, and the median survival time is short. ASCT and / or daratumumab may bring lasting relief for IgD MM patients, but large-scale clinical studies are still needed.
