OBJECTIVES: This study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty. METHODS: A total of 183 patients who underwent primary SF repair for cleft lip and palate before 18 months of age were included. Follow-ups were conducted at different ages, and digital dental casts of the maxillary dental arch were obtained using 3-matic Research 12.0 software. The length and width of the dental arch and palate were measured to explore developmental changes in the maxillary dental arch of the patients after the procedure. The study also investigated the influence of gender, age, cleft palate type, and relaxation incision on maxillary dental arch development. RESULTS: After SF, maxillary dental arch measurements showed statistically significant differences between children aged 0-2 years and those aged 3-6 years (P<0.05). However, no statistically significant differences were observed among different age groups within the 3-6 years range. Statistically significant differences were detected between males and females, with males having greater width of the posterior dental arch and palate (P=0.001) and shorter length of the anterior dental arch and entire dental arch (P<0.05). The unilateral cleft lip and palate group had shorter dental arch length (P<0.01) and wider posterior palate (P<0.01) than the cleft palate only group. Maxillary dental arch measurements had no statistically significant differences between groups with or without a relaxing incision. CONCLUSIONS Gender and age influence the width of the maxillary dental arch in children aged 0-6 years after SF, while age and cleft palate type affect dental arch length.

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.

Purpose To compare the expression and pattern of EBNA2 in infectious mononucleosis(IM),EBV-positive diffuse large B-cell lymphoma(EBV+DLBCL),and EBV+DLBCL arising in immune deficiency/dysregulation(IDD-related EBV+DLBCL),and to investigate the potential diagnostic value of EBNA2 in IM and EBV-associated diffuse large B-cell lymphoma.Methods A retrospective study was conducted on 46 cases of IM,31 cases of EBV+DLBCL,and 16 cases of IDD(post-transplantation)-related EBV+DLBCL.Clinical information,immunohistochemis-try and EBER were reviewed to further confirm the diagnoses.All samples were stained for EBNA2.The expression ra-tio and intensity of EBER and EBNA2 in the same area were assessed.Results EBER was positive in all IM,EBV+DLBCL,and IDD(post-transplantation)-related EBV+DLBCL,while the positivity rate of EBNA2 was 95.65％,6.45％,and 100％,respectively.The positive intensity of EBNA2 was weak(71.73％),strong(87.5％)and nega-tive(93.54％)in IM,IDD(post-transplantation)-related EBV+DLBCL and EBV+DLBCL respectively.The average values of EBNA2/EBER were 31％,3％,and 78％among the three groups.The positivity rate and average value of EBNA2/EBER in IM were significantly higher than those in EBV+DLBCL(P＜0.001);however,the average value of EBNA2/EBER was significantly lower than that in IDD(post-transplantation)-related EBV+DLBCL(P＜0.001).The weak positive expression of EBNA2 in IM was significantly higher than that in EBV+DLBCL(P＜0.001),where-as strong positive expression of EBNA2 in IDD(post-transplantation)-related EBV+DLBCL was higher than that in IM(P＜0.001).Conclusion EBNA2 is often positive in IM and predominantly weakly positive,which is distinct from the pattern in EBV+DLBCL and IDD(post-transplantation)-related EBV+DLBCL.EBNA2 can serve as an effective marker for distinguishing them.

Objective To investigate the clinical efficacy of the traditional Chinese medicine(TCM)throat opening and brightening method in treating unilateral vocal cord paralysis(UVCP).Methods Sixty patients with UVCP were prospectively collected and randomly assigned to two groups:the Chinese herbal medicine group(trea-ted with Buyang Huanwu Decoction,n=30)and the throat opening and brightening method group(treated with TCM throat opening and brightening method,n=30).The clinical studies that had utilized injection laryngoplasty for the treatment of UVCP(historical control group).Evaluation indicators included the voice handicap index-10(VHI-10),GRBAS-G,objective acoustic measurements of voice(vocal intensity,F0,shimmer,jitter,HNR),and aerodynamic measurements(maximum phonation time,MPT).Results Before treatment,no significant differences were observed between the two groups in all the evaluation indicators(P＞0.05).Post-treatment,the throat open-ing and brightening method group demonstrated significant improvements in VHI-10,GRBAS-G,shimmer,jitter,HNR,and MPT compared to pre-treatment values(P＜0.01),and these improvements were superior to those in the Chinese herbal medicine group.Pre-treatment VHI-10,GRBAS-G,and shimmer scores in the throat opening and brightening method group were significantly higher than those in the historical literature group(P＜0.01).Af-ter treatment,no significant differences were noted in any assessed parameters between the two groups(P＞0.05).Conclusion The TCM throat opening and brightening method significantly enhances phonatory function and quality of life in patients with UVCP,showing comparable efficacy to injection laryngoplasty.

AIM:To investigate the therapeutic effects and potential mechanism of pachymic acid(PA)on li-popolysaccharide(LPS)-induced acute kidney injury(AKI)in mice.METHODS:(1)Genes related to AKI were screened using the DAVID database.Core genes were identified by intersecting related genes and analyzed using Cyto-scape software.Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)analyses were performed through the DAVID database for the cross-targets.Molecular docking and activity assays were conducted on the primary core targets.(2)A total of 100 C57BL/6J mice were randomly divided into five groups:normal control(NC),model(LPS),solvent control(LPS+DMSO),and treatment groups(LPS+PA-10 and LPS+PA-20),with 20 mice in each group.The LPS-AKI model was established by intraperitoneal injection of 18 mg/kg LPS.The treatment groups received 10 mg/kg and 20 mg/kg PA,respectively,and the solvent control group was administered an equivalent dose of DMSO.Mice were euthanized 24 h after injection.Serum was collected for biochemical analysis,and Western blot was used to detect neutro-phil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),caspase-3,cleaved caspase-3,interleu-kin-1β(IL-1β),and monocyte chemoattractant protein-1(MCP-1)protein expression.RT-qPCR was employed to detect inflammatory factor mRNA levels.Molecular docking was used to simulate the optimal binding site of PA to caspase-3.En-zyme activity assays were performed to assess caspase protein activity,and renal lesions were observed via hematoxylin and eosin(HE)staining.Apoptosis was detected by TUNEL staining.RESULTS:(1)Thirty-one potential targets of PA against AKI were identified through network pharmacology.GO and KEGG enrichment analyses indicated that these tar-gets were primarily involved in immune response,inflammatory processes,apoptosis and survival,angiogenesis and hemo-dynamics,oxidative stress,and endoplasmic reticulum stress.Key targets included CASP3(caspase-3),PTGS2,BCL2,CCL2,and CYP219.(2)PA treatment improved renal function and reduced tubular epithelial injury.It significantly de-creased NGAL,KIM-1,and cleaved caspase-3 protein levels,as well as inflammatory factors TNF-α,IL-1β,and MCP-1 mRNA and protein expression.PA also reduced apoptosis of renal tubular epithelial cells.Enzyme activity assays and mo-lecular docking revealed that PA exerted its anti-apoptotic effect by directly binding to caspase-3,thereby inhibiting its ac-tivation by caspase-8.CONCLUSION:PA demonstrated a therapeutic effect in LPS-AKI,potentially through the inhibi-tion of inflammatory factor synthesis and release,as well as the inhibition of caspase-3 activation by caspase-8,reducing apoptosis in renal tubular epithelial cells.

OBJECTIVE To analyze the risk factors for peripherally inserted central catheter(PICC)central line-as-sociated bloodstream infection in cancer patients and explore corresponding management strategies.METHODS The data of 52 chemotherapy patients with PICC central line-associated bloodstream infection(PICC-CLABSI)ad-mitted to the Department of Gastroenterology of the First Affiliated Hospital of Air Force Medical University be-tween May 2021 and May 2023 were collected retrospectively,and the patients were classified as the infection group.Additionally,183 chemotherapy patients without PICC-CLABSI during the same period were included as the non-infection group.Clinical data from both groups were collected.Logistic regression analysis was used to identify risk factors for PICC-CLABSI in cancer patients,and receiver operating characteristic(ROC)curves were employed to assess the accuracy of predictive variables.RESULTS A total of 57 pathogens were isolated from 52 patients with PICC-CLABSI,including 15 strains of Escherichia coli,12 strains of Klebsiella pneumoniae,9 strains of Pseudomonas aeruginosa and 9 strains of Staphylococcus aureus.Diabetes(OR=2.694),catheter in-dwelling time≥30 d(OR=7.146),number of chemotherapy(OR=6.617),maintenance frequency of once per week(OR=2.803)and maintenance method(OR=6.289)were identified as risk factors for PICC-CLABSI(P＜0.05).The area under the curve for the combined prediction of PICC-CLABSI was 0.904,with a sensitivity of 0.750 and a specificity of 0.907.CONCLUSIONS Diabetes,catheter indwelling time and number of chemotherapy are risk factors for PICC-CLABSI,while a maintenance frequency of once per week and the maintenance method are protective factors.Close attention should be paid to the assessment of risk factors after catheter placement,and targeted anti-infection strategies should be implemented.
