Objective:To investigate the anatomic origin of juvenile nasopharyngeal angiofibroma（JNA） through radiologic analysis of tumor invasion patterns, providing insights into tumor etiology and surgical recurrence prevention. Methods:This retrospective cohort study included primary JNA cases at the Department of Otorhinolaryngology, Eye and ENT Hospital of Fudan University from March 2015 to September 2024. All patients underwent preoperative high-resolution CT（HRCT） scans, and some underwent enhanced magnetic resonance imaging. The study retrospectively analyzed the patients' imaging data to examine tumor invasion into the pterygopalatine fossa and the vidian canal. These sites were categorized into non-invaded, partially invaded, and completely invaded for the pterygopalatine fossa and the vidian canal. The study analyzed the proportions of invasion at these sites to further speculate on the origin of JNA. Results:A total of 105 JNA patients were included in the study. Among them, 100% of the patients had complete tumor invasion in the pterygopalatine fossa. For the vidian canal, the proportions of complete invasion, partial invasion, and non-invasion were 54.3%, 27.6%, and 18.1%, respectively. As the staging of JNA tumors increased, the proportion of vidian canal invasion also increased. Conclusion:Our evidence suggests that the pterygopalatine fossa, rather than the vidian canal, might be the likely origin of JNA, which is enlightening for the study of the etiological mechanisms of JNA.

Objective:To investigate the effects of prognostic nutritional index (PNI) on the readmission rate, complication rate, mortality rate and survival of patients with liver cirrhosis.Methods:From January 1, 2020 to December 31, 2022, 395 hospitalized patients with liver cirrhosis at Tianmen Hospital Affiliated to Wuhan University of Science and Technology were retrospectively enrolled. The clinical data were collected from the patients at their first hospitalization (baseline period) and re-hospitalization during follow-up period. The 18-month follow-up was divided into 4 periods, including the first period (from the 0th to the 3rd month), the second one was from the 4th to the 6th month, the third one was from the 7th to the 12th month, and the fourth one was from the 13th to the 18th month of follow-up. The prognostic value of PNI for patients with liver cirrhosis was evaluated through the receiver operating characteristic curve (ROC) of the baseline PNI. The 395 patients were divided into the low PNI group and the high PNI group based on the optimal cut-off value of PNI on the ROC. Patients readmitted during each follow-up period were divided into the PNI improvement group (PNI at follow-up -PNI at baseline>0) and the PNI non-improvement group (PNI at follow-up-PNI at baseline ≤0). Independent sample t-test, one-way analysis of variance (ANOVA), Mann-Whitney U test, chi-square test or Fisher′s exact test were used for statistical analysis. Survival curves depicting the relationship between PNI and overall survival rate of patients with liver cirrhosis were constructed using the Kaplan-Meier method. Results:The ROC analysis indicated that the optimal cut-off value of PNI at baseline was 32.65, with an area under the curve of 0.639 (95% confidence interval: 0.541 to 0.738, P=0.011), with a sensitivity of 0.567 and a specificity of 0.701. There were 269 cases in the high PNI group and 126 cases in the low PNI group. The readmission rate, complication rate and mortality rate in the low PNI group were all higher than those in the high PNI group at the first and fourth follow-up periods (32.5% (41/126) vs. 22.3% (60/269), 31.7% (40/126) vs. 20.4% (55/269), 6.3% (8/126) vs. 1.1% (3/269), 25.0% (29/116) vs. 16.2% (42/260), 25.0% (29/116) vs. 15.4% (40/260), 6.0% (7/116) vs. 1.5% (4/260)), and the differences were statistically significant ( χ2=4.72, 6.00, 6.86, 4.10, 4.95, and 4.24; P=0.030, 0.014, 0.009, 0.043, 0.026, and 0.040). The mortality rates of the PNI improvement group at the first and fourth follow-up periods were both lower than those of the PNI non-improvement group (4.3% (2/47) vs. 16.7% (9/54), 0 (0/24) vs. 23.4% (11/47)), and the differences were statistically significant ( χ2=3.99, Fisher′s exact test; P=0.046 and 0.012). There were no statistically significant difference in the incidence of complications between the PNI improvement group and the PNI non-improvement group at each follow-up period (all P>0.05). The Kaplan-Meier survival curve demonstrated that the average survival time of the high PNI group was longer than that of the low PNI group (17.54 months (95% confidence interval: 17.26 to 17.83 months) vs. 16.74 months (95% confidence interval: 16.96 to 17.52 months), and the difference was statistically significant ( χ2=9.18, P<0.001). The survival rate of the high PNI group at the 18th month of follow-up period was higher than that of the low PNI group (95.2% (256/269) vs. 86.5% (109/126), and the difference was statistically significant ( χ2=9.17, P=0.002). Conclusions:PNI has certain predictive efficacy for the survival period of patients with liver cirrhosis. Low-level PNI may increase the readmission rate, complication rate, and mortality of patients with liver cirrhosis, and shorten the survival period, indicating poor prognosis.

Objective:To construct and validate a predictive model for postoperative recurrence in early non-small cell lung cancer patients.Methods:The clinical data of 252 patients with early non-small cell lung cancer admitted to the 926th Hospital of Joint Logistic Support Force of PLA from January 2016 to January 2018were retrospectively collected. All of the patients underwent surgical treatment and they were followed up for 5 years after surgery, according the recurrence after surgery, they were divided into the recurrence group (103 cases) and non- recurrence group (149 cases). The risk factors for postoperative recurrence in early non-small cell lung cancer patients were analyzed. A predictive model for postoperative recurrence in early non-small cell lung cancer patients was constructed and validated.Results:The results of Logistic regression analysis showed that tumor long diameter≥ 3 cm, lymph node metastasis, low differentiation, spicules and pleural traction were independent risk factors for postoperative recurrence in early non-small cell lung cancer patients ( P<0.05). Using R4.0.3 statistical software, the dataset was randomly divided into a training set and a validation set, with a sample size of 176 cases in the training set and 76 cases in the validation set. A prediction model was constructed, with thearea under the curve (AUC) of the receiver operating characteristic (ROC) curve of 0.754 (95% CI 0.679 - 0.828) in the training set and AUC of 0.749 (95% CI 0.634 - 0.864) in the validation set. The model was subjected to a Hosmer-Lemeshow Goodness-of-Fit Test in the validation set, χ2 = 11.31, P = 0.185. Conclusions:The predictive model base on tumor long diameter ≥ 3 cm, lymph node metastasis, low differentiation, spicules and pleural traction can identify patients at high risk of postoperative recurrence in early non-small cell lung cancer effectively.

BACKGROUND:As an essential trace element for body growth and development,copper participates in many processes such as redox process,energy generation,signal transduction and bone metabolism.The imbalance of copper homeostasis in diabetic patients will lead to the increase of oxidative stress and the impairment of antioxidant mechanism,which stimulate the production of inflammatory mediators and inflammatory factors,and thus lead to cytotoxicity and body damage.In recent years,the role of copper in diabetes has gradually attracted attention,and some studies have confirmed that copper plays a key regulatory role in the pathological process of diabetes.OBJECTIVE:To summarize the current progress in the role of copper in systemic complications of diabetes and provide some theoretical reference for its future research and treatment.METHODS:The first author searched PubMed,Web of Science,CNKI and WanFang databases for literature related to the role of copper in systemic complications of diabetes.The search terms were"copper,Cu,diabetes,diabetic complications,diabetic cardiomyopathy,diabetic nephropathy,diabetic retinopathy,diabetic osteoporosis,diabetic periodontitis"in English and Chinese,respectively.After screening,95 articles were included in the review.RESULTS AND CONCLUSION:(1)Copper is involved in the occurrence and development of diabetic complications and most of the damage caused by copper to the body is due to interference with the body's redox level.(2)In diabetic cardiomyopathy,increased Cu2+in the corpuscular circulation and impaired uptake of copper ions by cardiomyocytes,the accumulation of redox-active Cu2+and ceruloplasmin outside the cardiomyocyte induces copper oxidative stress in cardiomyocytes,leading to acute cardiac impairment.(3)In diabetic nephropathy,the toxic effect of excessive copper leads cause granular degeneration and vacuolar degeneration of renal tubular epithelial cells and proximal tubular necrosis,eventually leading to chronic or acute renal failure.(4)Excessive copper in diabetic patients can produce reactive oxygen species and directly or indirectly affect the function of copper protein with antioxidant function,thus damaging retinal cells.(5)In patients with diabetic osteoporosis,accumulated copper induces lipid peroxidation and interferes with bone metabolism.Copper acts on osteoblasts mainly through inhibition of superoxide dismutase,glutathione peroxidase,and alkaline phosphatase activities.(6)Excessive copper exacerbates inflammatory changes in periodontal tissue by promoting inflammatory responses.

Objective To investigate the clinical characteristics and pathogen resistance of vulvovaginitis among prepubertal children in Xi'an area,so as to provide valuable insights for clinical diagnosis and treatment.Methods A total of 1 019 children(aged<10 years)diagnosed with prepubertal vulvovaginitis in Xi'an Children Hospital from January 2019 to December 2023 were selected as the research objects.The clinical characteristics and drug resistance of pathogenic bacteria were analyzed.Results The number of children with prepubertal vulvovaginitis increased significantly after the end of the COVID-19 pandemic.The positive detection rate in 2023 increased by 13.18%compared to that in 2019,with a significant rise in bacterial vulvitis compared to fungal infection.Common clinical manifestations among diagnosed children included increased secretion and vulvar pruritus.As age increased,the detection rate of pathogenic bacteria also rose,reaching a high positive proportion of 37.29%among children aged 8～<10 years old.Pathogenic bacteria isolated in the laboratory mainly consisted of Haemophilus influenzae(30.72%,313/1 019),Candida albicans(28.46%,290/1 019)and Streptococcus pyogenes(20.61%,210/1 019).Notably,the detection rates of these pathogens exhibited significant variations among children of different age groups(χ2=279.26,382.97,83.48,all P<0.05).Among them,vulvitis in children under 8 years old were mainly caused by respiratory bacterial infections,while those aged 8～<10 tended to be consistent with adults and were mainly caused by candidal vulvitis.The drug sensitivity test results indicated that Haemophilus influenzae exhibited high resistance rates to ampicillin and cefuroxime but good sensitivity to third-generation cephalosporins.Candida albicans showed good sensitivity to common antifungal drugs.Streptococcus pyogenes displayed high sensitivity to penicillin,ampicillin and ceftriaxone but strong resistance(>90%)against erythromycin and clindamycin.Conclusion The positive rate of vulvitis has been increasing among prepubertal children in Xi'an recent years.Pathogenic bacteria are concentrated and sensitive towards common antibiotics.Early submission of clinical samples,rational use of medications and reinforcement on healthy habits guidance are recommended for timely intervention in the development of the disease.

BACKGROUND:With the development of computer-aided design and computer-aided manufacturing technology,zirconia abutments with a titanium base are widely used in clinic due to its good application advantages,but there are still some problems and a lack of consensus design standards. OBJECTIVE:To review the fabrication methods of Ti-base zirconia abutment,and the effect of abutment connection,emergence design,abutment angle,and bonding on mechanical properties of Ti-base zirconia abutment. METHODS:Relevant literature published from 2010 to 2023 was searched in CNKI and PubMed databases with the search terms"zirconia abutment,titanium base"in Chinese and English,respectively.The search time limit was extended for some classical literature.The relevant literature was obtained through inclusion and exclusion criteria,and 57 eligible documents were included for review. RESULTS AND CONCLUSION:It is recommended that clinicians try to select antirotational titanium bases or rotational titanium bases with a Morse taper connection.Implants should be placed in the correct axial angulation of not more than 15° or with an inclination to the palatal side when using angled zirconia abutments.When a≥30° labial inclination is followed for implant placement,the bite force must be decreased effectively to reduce the risk of mechanical and biological complications of implants,abutments,and prostheses.Ti-base zirconia abutments with a higher gingival height should be selected,and its restorative angle should not exceed 40°.Multilink Hybrid Abutment could be the first choice for extraoral bonding of zirconia abutment to titanium bases.

BACKGROUND:Unlike non-inflammatory cell apoptosis,pyroptosis is a form of inflammatory cell death,characterized by membrane integrity disruption and release of pro-inflammatory intracellular substances.Thus,it is associated with various diseases.The sirtuin family is a group of histone deacetylases dependent on nicotinamide adenine dinucleotide.In addition to deacetylation,it also possesses other enzymatic activities such as desuccinylation,demalonylation,adenosine diphosphate-ribosylation and playing crucial roles in the regulation of pyroptosis.OBJECTIVE:To review the role of the sirtuins in pyroptosis.METHODS:The first author conducted a search on PubMed,Web of Science,CNKI,and WanFang Data from inception to March 2024,using the Chinese and English search terms"Sirtuins,Sirtuin1,Sirtuin2,Sirtuin3,Sirtuin4,Sirtuin5,Sirtuin6,Sirtuin7,pyroptosis",resulting in the inclusion of 71 articles.RESULTS AND CONCLUSION:(1)The sirtuin family all participates in the regulation of pyroptosis.(2)Overexpression of sirtuin1 and sirtuin4 can inhibit pyroptosis through various pathways,thus alleviating the damage caused by pyroptosis to the organism.(3)In addition to affecting the classical pathway of pyroptosis,sirtuin3 can also inhibit pyroptosis by enhancing mitochondrial reactive oxygen species scavenging capacity and mitosis.(4)Sirtuin5 is involved in the regulation of intracellular metabolism and energy balance,including energy intake,storage,and consumption.(5)Sirtuin6 can influence pyroptosis through various pathways and also affect macrophage M1 polarization,generation of reactive oxygen species,and cleavage of pyroptosis-related factor sclerotin D to inhibit pyroptosis.(6)Overexpression of sirtuin7 can suppress pyroptosis.(7)Sirtuin2,unlike other family members,can restrain pyroptosis only after knockdown,but there are fewer reports,requiring more in-depth and comprehensive research.

Developmental dysplasia of the hip (DDH) is the most common bone developmental disorder in children, emphasizing the need for effective, standardized, and accurate screening and treatment approaches. This paper reviews traditional ultrasound diagnostic methods for DDH in children aged 0-6 months and examines the latest advancements in artificial intelligence (AI)-assisted ultrasound technology. It compares the diagnostic accuracy, efficiency, and limitations of these approaches while addressing controversies surrounding the adoption of AI. Results indicate that AI-assisted ultrasound significantly outperforms traditional methods in both accuracy and efficiency but also raises concerns about over-diagnosis and over-treatment. Despite these challenges, AI-assisted ultrasound holds immense potential, and with technological advancements, it is expected to gain wider acceptance among clinicians, enhancing its application in clinical practice.

Objective:To investigate the clinical characteristics of limb overgrowth following proximal femoral osteotomy (PFO) for unilateral developmental dysplasia of the hip (DDH) in children.Methods:A retrospective analysis was conducted on 36 children with unilateral DDH who underwent PFO at Xi'an Honghui Hospital from June 2017 to June 2021. The cohort included 4 males and 32 females, with a mean age of 4.23±3.15 years (range: 2-12 years), comprising 28 left-sided and 8 right-sided cases. According to the International Hip Dysplasia Institute (IHDI) classification, there were 2 type I, 9 type II, 16 type III, and 9 type IV cases. Radiographic parameters [femoral length, femoral neck anteversion angle, neck-shaft angle, acetabular index (AI), center-edge angle (CEA), center-head distance discrepancy (CHDD)] and PFO parameters (varus angle, shortening length, derotation angle) were measured on X-ray and 3D CT reconstructions. Comparisons were made between the overgrowth ≥1 cm group ( n=14) and <1 cm group ( n=22) to analyze risk factors and patterns. Results:The overgrowth ≥1 cm group had significantly younger patients (2.49±1.03 years vs. 5.13±3.47 years, t=-2.757, P<0.001). Overgrowth magnitude varied significantly across age subgroups: 11.08±6.17 mm in the 2-4 years group, 5.08±0.19 mm in the >4-<6 years group, and 2.44±4.50 mm in the ≥6 years group ( F=5.436, P=0.031). The highest incidence of overgrowth occurred in the 2-4 years subgroup (56%, 20/36). Limb overgrowth initiated at 3 months postoperatively, exhibited a linear correlation with follow-up duration during 6-18 months [ r=0.78, 95% CI(0.62, 0.88), P<0.001)], and plateaued after 18 months [ r=-0.15, 95% CI(-0.75, 0.57), P=0.710]. Postoperative CEA and CHDD showed significant improvements ( P<0.05), while AI remained unchanged ( P>0.05). Conclusions:Children aged 2-4 years exhibit higher incidence and severity of post-PFO limb overgrowth. The rapid progression phase occurs within 6-18 months postoperatively, stabilizing thereafter. CEA and CHDD serve as critical indicators for evaluating intervention efficacy in DDH-related overgrowth.
