Objective:
To retrospectively compare the safety and efficacy of ultrasound-guided radiofrequency ablation (RFA) with parotidectomy for superficial pleomorphic adenoma (PA).
Materials and Methods:
From March 2022 to October 2023, 88 patients diagnosed with superficial parotid PA underwent either RFA (n = 12; mean age, 47.1 years) or parotidectomy (n = 76; mean age, 47.8 years). Patients in the RFA group were matched to those in the surgery group in a 1:1 ratio using propensity scores based on age, sex, tumor volume, diameter, location, and comorbidities. Ultrasound characteristics, cosmetic scores (0–4), numerical rating scale scores (0–10), and complications were assessed before the procedures and at 1-, 3-, and 6-month follow-ups. Outcomes were compared between baseline and follow-up in the RFA group and between the RFA and surgery groups.
Results:
In the RFA group, significant reductions in tumor volume were observed between baseline (median, 2.02 cm 3 ) and the 1-month follow-up (median, 1.21 cm 3 ; P = 0.015), between the 1-month and 3-month follow-ups (median, 0.53 cm 3 ; P= 0.002), and between the 3- and 6-month follow-ups (median, 0.23 cm 3 ; P = 0.003). The volume reduction ratios at 1, 3, and 6 months were 39.7%, 79.9%, and 88.0%, respectively. The cosmetic score was significantly lower at 3- and 6-month followup compared to baseline (median 1 and 1 vs. 4, P = 0.04). The numerical rating scale scores did not differ significantly from baseline throughout follow-up. In the propensity score-matched analysis (12 patients per group), RFA was associated with a shorter median procedure time (61.5 vs. 253.3 minutes; P < 0.001), shorter hospital stay (0 vs. 4 days; P < 0.001), and lower cost (1859.9 vs. 3512.4 USD; P < 0.001) than parotidectomy, with no significant difference in overall complication rates (33.3% [4/12] vs. 41.7% [5/12]; P = 1.000).
Conclusion
RFA may be a safe and effective alternative to surgery for superficial parotid PA, offering a shorter median procedure time, shorter hospital stay, and lower costs.

Objective:
To investigate the prevalence and influencing factors of menopausal syndrome among postmenopausal women in Pan'an County, Zhejiang Province, so as to provide the basis for guiding the health management of postmenopausal women.
Methods:
From May 2023 to April 2024, the postmenopausal women aged 40 to 69 years in Pan'an County were selected using the random cluster sampling method. Demographic information, lifestyle and prevalence of gynecological diseases were collected through questionnaire surveys. The prevalence of menopausal syndrome was assessed by modified Kupperman Score Scale. Factors affecting menopausal syndrome were analyzed by a multivariable logistic regression model.
Results:
A total of 816 postmenopausal women were surveyed, with an mean age of (57.63±2.92) years and a mean natural menopause age of (49.85±2.13) years. There were 574 cases with menopausal syndrome, with a prevalence of 70.34%. Flashes and sweating, insomnia and irritability were common symptoms, accounting for 62.87%, 47.43% and 41.18%, respectively. Multivariable logistic regression analysis showed that monthly personal income of ≤5 000 yuan (<3 000 yuan, OR=3.124, 95%CI: 1.829-5.335; 3 000-5 000 yuan, OR=2.399, 95%CI: 1.370-4.201) and having gynecological diseases (OR=1.970, 95%CI: 1.292-3.004) were associated with a higher risk of menopausal syndrome, while average (OR=0.141, 95%CI: 0.072-0.276) or sufficient sleep quality (OR=0.095, 95%CI: 0.049-0.185) were associated with a lower risk of menopausal syndrome.
Conclusion
The prevalence of menopausal syndrome among postmenopausal women in Pan'an County is relatively high, and is mainly influenced by personal economic status, sleep quality and the presence of gynecological diseases.

Gliomas, especially high-grade gliomas such as glioblastoma multiforme (GBM), are primary malignant tumors of the central nervous system, characterized by high proliferative capacity, invasiveness, and therapeutic resistance. The development of GBM relies heavily on continuous metabolic reprogramming to adapt to the unique intracranial microenvironment, with nicotinamide adenine dinucleotide (NAD+) metabolic remodeling playing a pivotal role. Dysregulation of NAD+ and its associated metabolic pathways sustains increased intracellular NAD+ levels, which drive the malignant proliferation and invasive potential of GBM, correlating with worsened patient prognosis. This review systematically summarizes the current research landscape of NAD+ metabolic remodeling in GBM, elucidates the mechanisms by which NAD+ contributes to GBM pathogenesis and progression, and explores the clinical potential of NAD+-targeted diagnostic and therapeutic strategies to provide novel insights and directions for the clinical management of GBM.

Ecto-nucleotide pyrophosphatases/phosphodiesterases(ENPPs)are involved in the hydrolysis of different purine nu-cleotides in a range of physiological processes.In recent years,it has also been found to be involved in tumor progression,with ENPP1 often overexpressed in local recurrence and tumor metas-tasis,which is associated with poor prognosis and survival in a range of solid tumors.The role of ENPP1 in tumors is mainly fo-cused on tumor proliferation,metastasis,immunity,recurrence,etc.,and it is speculated that ENPP1 can be used as a prognos-tic indicator for a variety of tumors.ENPP1 promotes the immu-nosuppressive tumor microenvironment by being obliquely in-volved in the regulation of ATP/adenosine homeostasis by com-bining with other components,which crosses with interferon gene stimulators to impair its potent immune response through the hy-drolysis of the effector 2',3'-cyclic GMP-AMP.Therefore,EN-PP1 blockade has become an effective means to induce immune remodeling and inhibit tumorigenesis and development.The ex-isting ENPP1 inhibitors mainly include natural small molecule compounds,nucleotide ENPP1 inhibitors,non-nucleotide EN-PP1 inhibitors,and novel small molecule ENPP1 inhibitors.So far,a small number of ENPP1 inhibitors have been developed and are rarely suitable for in vivo experiments,and they are still in the stage of developing effective compounds or lead com-pounds,and the research on ENPP1 inhibitors needs to be fur-ther studied.This review summarizes and discusses the role of ENPP1 in tumors,and summarizes the current research progress of various ENPP1 agents and their current research progress,in order to provide a reference for further research on the prepara-tion of drug candidates.

Objective:To analyze the clinical, genetic, and bioinformatic characteristics of 3 children diagnosed with GM1 gangliosidosis type Ⅰ, and to conduct a literature review.Methods:From January 2020 through December 2022, a detailed examination, encompassing whole-exon sequencing and the evaluation of β-galactosidase enzymatic function, was undertaken for 3 pediatric inpatients at Xi′an Children′s Hospital. Each child presented with distinct clinical features: recurrent seizures, developmental delays, and hypotonia. Concurrently, computational tools MutaBind2 and PyMOL were employed to prognosticate the potential impact of identified genetic mutations.Results:All 3 children experienced severe developmental delay or regression in infancy, accompanied by epilepsy. Serum alkaline phosphatase and aspartate aminotransferase were significantly increased. Furthermore, the serum β-galactosidase activity was 1.59%, 3.47%, 1.96%,respectively. Brain magnetic resonance imaging revealed poor myelination and X-ray examinations demonstrated beak-like changes in the anterior edge of the lumbar spine. All 3 children carried compound heterozygous variants in the GLB1 gene. The c.148T>C variant had not been previously reported, while the c.785G>T, c.1438A>G and c.304C>G variants were only present in 1 case. It was predicted that the mutated protein exhibited reduced binding affinity, with an interrupted hydrogen bond or the formation of a significant steric hindrance with the neighboring residues. Combined with the literature evidence, it was hypothesized that the mutations could potentially impact the overall structure and stability of the GLB protein, leading to a decrease in enzyme activity. Conclusions:The diagnosis and classification of GM1 ganglioside storage disease need to integrate the clinical features, exome sequencing and β-galactosidase activity assay. Bioinformatics analysis is helpful to predict the effect of mutations on protein structure and function.

Objective To study the diagnosis,treatment,and complications of hypophosphatemic rickets(HR)in children,explore effectiveness evaluation indicators for the disease,and understand the pattern in height growth among these patients.Methods A retrospective analysis of the initial clinical data and five-year follow-up data of 85 children with HR treated at Children's Hospital of Nanjing Medical University from January 2008 to December 2022.Results Among the 85 children with HR,there were 46 males(54%)and 39 females(46%).The age at initial diagnosis ranged from 6 months to 13 years and 9 months,with a median age of 2.75 years.The average height standard deviation score was-2.0±1.1.At initial diagnosis,children exhibited reduced blood phosphate levels and elevated alkaline phosphatase(ALP),with 99%(84/85)presenting with lower limb deformities.The positive rate for PHEX gene mutations was 93%(55/59).One year post-treatment,there was a significant reduction in ALP levels and the gap between the lower limbs(P<0.05).The fastest height growth occurred in the first year after treatment,at 8.23 cm/year,with a peak height velocity(PHV)phase lasting about two years during puberty.The height increased by 9-20 cm in male children during the PHV stage and 10-15 cm in female children.Major complications included nephrocalcinosis and hyperparathyroidism.The incidence rate of nephrocalcinosis in the first year after treatment was 55%(22/40),which increased with the duration of the disease(P<0.001);an increased urinary phosphate/creatinine ratio was positively associated with a higher risk of nephrocalcinosis(OR=1.740,P<0.001).The incidence of hyperparathyroidism in the first year after treatment was 64%(27/42).Conclusions For children presenting with lower limb deformities,short stature,and slow growth,early testing for blood levels of phosphate,calcium,and ALP,along with imaging examinations of the lower limbs,can aid in the early diagnosis of HR.Genetic testing may be utilized for definitive confirmation when necessary.ALP combined with improvements in skeletal deformities and annual height growth can serve as indicators of therapeutic effectiveness for HR.Compared to normal children,children with HR demonstrate a lower height increase during the PHV phase,necessitating close follow-up and timely adjustment of treatment plans
