ObjectiveTo analyze the clinical treatment plan and traditional Chinese medicine （TCM） medication rule of children with primary nephrotic syndrome （PNS） in the First Affiliated Hospital of Henan University of Chinese Medicine. MethodsThe gender and age of children firstly diagnosed with nephrotic syndrome in the pediatric nephrology department of the First Affiliated Hospital of Henan University of Chinese Medicine from November 2019 to December 2022 were collected， and the use of immunosuppressive agents and related frequencies were counted. According to the inclusion and exclusion criteria， an independent TCM prescription database for children with nephrotic syndrome was established. Excel was used to analyze the relevant information of the literature. The frequency counting， association rule analysis， and cluster analysis were carried out on TCM in the prescription， and the high-frequent drugs were analyzed. Results（1） General information： A total of 711 children were included， consisting of 522 males （73.42%） and 189 females （26.58%）. The ratio of male to female was about 2.76∶1. The disease mainly occurred in infants and preschool age， and the average age of onset was （4.74 ± 3.48） years old. （2） Clinical treatment plan and use of immunosuppressive agents： Of the 711 children with PNS， 237 were treated with hormone alone （32.33%）， and 474 （66.67%） received immunosuppressive agents combined with hormones. In the initial treatment， hormone combined with Tacrolimus （TAC） was the preferred treatment （32.91%）. For children with refractory PNS who exhibited poor clinical efficacy， Rituximab （RTX） was mostly used for treatment， with a ratio of up to 23.63%. （3） TCM syndrome and medication rule： In PNS syndrome differentiation， Qi and Yin deficiency was identified as the main syndrome. This involved a total of 477 cases， accounting for 67.09%. Yang deficiency of spleen and kidney was observed in 118 cases， accounting for 16.60%. A total of 711 children were included， of which 706 children were treated with TCM. This involved a total of 706 prescriptions， 226 TCM， and 9 793 frequencies. There were 30 herbs used more than 95 times. The top five TCM were Radix et Rhizoma Glycyrrhizae （81.16%）， Radix Astragali （71.81%）， Poria （68.84%）， Rhizoma Atractylodis Macrocephalae （63.60%）， and Fructus Corni （57.37%）. The drug association rules and network diagram showed that the combination of ''Radix Astragali-Rhizoma Atractylodis Macrocephalae-Poria'' was the closest， and five types of combinations were obtained by cluster analysis. ConclusionIn the diagnosis and treatment of PNS in children， TAC combined with hormones shows good clinical efficacy and high safety. For children with refractory PNS， RTX combined with hormones can be used. TCM medication for PNS should follow the basic principles of strengthening the body and vital Qi and make good use of drugs such as Radix Astragali， Poria， Rhizoma Atractylodis Macrocephalae， and cornus to regulate the Yin and Yang balance and achieve better clinical efficacy.

Objective This study aims to elucidate the functional mechanism through which seminal plasma exosomal miR-26a-5p and its target genes contribute to idiopathic teratozoospermia,with emphasis on their regulatory pathways in sperm morphogenesis defects,thereby establishing a theoretical foundation for novel diagnostic markers and targeted therapies.Methods A case-control study design was adopted,enrolling 154 male subjects(84 in the teratozoospermia group[TZS]and 70 in the normal control group[NC]).Seminal plasma exosomes were isolated to screen differentially expressed miRNAs,followed by prediction and analysis of target genes and signaling pathways.Dual-luciferase reporter gene assays were employed to validate the direct binding of miR-26a-5p to PTEN.Quantitative real-time PCR and Western blot were used to measure miRNA and protein expression levels.Spearman correlation analysis evaluated relationships between miR-26a-5p,PTEN,and sperm morphological parameters,while ROC curve analysis assessed diagnostic efficacy.Results Seminal plasma exosomal miRNA sequencing identified 11 differentially expressed miRNAs,with miR-26a-5p significantly upregulated in the TZS group(P<0.05)and negatively correlated with the percentage of normal sperm morphology in TZS(r=-0.762,P<0.05).PTEN was confirmed as a direct target of miR-26a-5p,with its expression significantly reduced in the TZS group(P<0.05)and positively correlated with normal sperm morphology(r=0.821,P<0.05).A negative correlation was observed between miR-26a-5p and PTEN(r=-0.878,P<0.05).Dual-luciferase assays demonstrated that miR-26a-5p specifically inhibited PTEN 3'UTR activity(45%reduction in luciferase activity,P<0.05).Functional enrichment analysis revealed that the miR-26a-5p-PTEN axis exacerbates oxidative stress,DNA damage,and abnormal spermatocyte division by regulating the PI3K/AKT/mTOR,p53,Wnt/β-catenin,and NF-κB pathways.ROC analysis showed diagnostic efficacy for teratozoospermia with AUCROC values of 0.785(sensitivity 78.9%,specificity 71.3%)for miR-26a-5p and 0.754(sensitivity 73.3%,specificity 75.1%)for PTEN.Conclusions miR-26a-5p suppresses PTEN through targeted inhibition,activating PI3K/AKT/mTOR signaling pathways while impairing DNA repair functions.This cascade leads to accumulated oxidative stress and sperm morphological abnormalities.The combined pattern of elevated seminal plasma exosomal miR-26a-5p expression and reduced PTEN levels demonstrates diagnostic potential for idiopathic teratozoospermia,with its molecular mechanism providing a theoretical foundation for biomarker development.Targeted silencing of miR-26a-5p,either alone or in combination with AKT/mTOR inhibitors and antioxidant therapy,may represent a novel strategy for improving sperm morphology.

In modern society, sugary foods have become an integral part of many people′s lives. However, excessive sugar consumption has adverse effects on both overall health and oral health, serving as a contributing factor to the global increasing incidence in oral diseases, cardiovascular diseases, cancers, obesity, and diabetes. In response to the health risks related to high-sugar diets, the World Health Organization (WHO) and World Dental Federation (FDI) have proposed initiatives and recommendations, with various governments implementing different policies and strategies to reduce sugar intake. Chinese government has also taken proactive measures. The "Healthy China Action (2019-2030)" initiative introduced by the State Council in 2019 established a crucial benchmark in limiting the average daily intake of added sugar to 25 g per person forward to 2030. Experts from Chinese Center for Disease Control and Prevention and the field of oral health have meticulously examined the impacts of sugar reduction on oral health, as well as strategies, methods, and practical considerations related to reducing sugar intake through several meeting and wrote the "Expert consensus: reducing free-sugar for caries prevention", which was subsequently reviewed and revised based on the feedback from multiple stakeholders. They have conducted thorough analyses of global trends in sugar reduction and best practices to provide valuable insights to China for crafting effective policies and strategies on sugar reduction. This consensus mainly includes the classification of free sugars, the latest scientific evidence on dental caries, recommendations from WHO on sugar-sweetened beverage taxes, nutrition labeling, advertising, food reform, adjusting supply systems, education, and promotion strategies, as well as sugar reduction actions taken by various governments around the world. Combining the actual situation in China, policy recommendations and authoritative popular science knowledge on sugar reduction for caries prevention to public are proposed to advocate for experts in multiple fields to focus on sugar reduction for caries prevention, promote the work process, and provide the scientific basis for oral health educators.

Objective To evaluate the correlation between MRI burden of cerebral small vessel disease and cognitive impairment in elderly hypertensive people.Methods Data of elderly hypertensive people with CSVD at Xingtai People's Hospital Affiliated to Hebei Medical University from January 2018 to September 2024 were analyzed.According to the total MRI burden score,patients were divided into mild to moderate(0-2)and severe(3-4)burden groups.The baseline data and cognitive impairment were compared between groups.The correlation between risk factors of MRI burden and cognitive impairment was analyzed.Results The severe burden group had higher systolic blood pressure[178(155,180)mmHg vs.159.50(147.75,170)mmHg,higher fasting blood glucose[5.70(5.37,5.92)mmHg vs.5.38(4.83,5.70)mmHg,P<0.05]and higher the proportion of cognitive impairment[8(28.1%)vs.3(6.8%),P<0.05]than the mild to moderate group.Multivariate logistic regression analysis revealed that systolic blood pressure(OR=1.033,95%CI:1.001-1.067,P<0.05)was the independent risk factor for total MRI burden.Spearman correlation analysis revealed that MRI total burden was negatively correlated with MMSE score(r=-0.315,P=0.011)and MoCA score(r=-0.662,P<0.001).Compared with the mild to moderate burden group,the severe group performed worse in the areas of orientation,attention and computation,language ability on the MMSE,and worse in visual space and executive ability,attention,language,delayed recall,and orientation on the MoCA(P<0.05).Conclusion Systolic blood pressure is the independent risk factor of MRI total burden in elderly hypertensive people.The higher the total MRI burden,the more severe the cognitive impairment,the worse performance in orientation,visual space and executive ability,attention and computation,language,and delayed recall.

Objective To explore the transvaginal three-dimensional ultrasound characteristics in women with abnormal uterine cavity and compare the diagnostic value with hysteroscopy.Methods A total of 102 women who underwent transvaginal three-dimensional ultrasound and hysteroscopy in the Department of Ultrasound of Lu'an People's Hospital for various reasons were selected as the research subjects.Hysteroscopy was the gold standard.The three-dimensional ultrasound characteristics of patients with different uterine cavity lesions were statistically analyzed.A 2×2 4-grid table was drawn to calculate the diagnostic value of transvaginal three-dimensional ultrasound for various types of uterine cavity lesions.Results There were 22 cases of endometrial polyps,9 cases of intrauterine adhesions,and 5 cases of submucosal fibroids.The accuracy rates of diagnosing endometrial polyps,intrauterine adhesions and submucosal fibroids through transvaginal three-dimensional ultrasound were 90.91%,88.89%and 80.00%,respectively.The transvaginal three-dimensional ultrasound of patients with endometrial polyps mainly showed deformation of the uterine cavity line,high echoic masses,clear differentiation between the edge of the echogenic mass and the endometrium,almost no deformation of the endometrial basal line,and scattered distribution of blood flow on CDFI ultrasound.Intrauterine adhesions mainly manifested as uneven endometrial thickness and low echogenicity by transvaginal three-dimensional ultrasound,and fluid accumulation may found in the uterine cavity of some patients.Transvaginal three-dimensional ultrasound showed that submucosal fibroids were mainly hypoechoic,elliptical or irregular in shape,with CDFI revealing abundant blood flow signals.Conclusion When women with abnormal uterine cavity are examined with transvaginal three-dimensional ultrasound,patients with different types of lesions have different typical ultrasound characteristics,and transvaginal three-dimensional ultrasound diagnosis has a high diagnostic accuracy with respect to hysteroscopy as the gold standard,exhibiting its advantages of non-invasive and rapid diagnosis,worthy of clinical promotion.

Objective:To compare the accuracy of two-dimensional (2D) ultrasound with three-dimensional (3D) reconstruction and conventional 2D ultrasound in measuring bladder volume in pelvic tumor patients, using computed tomography (CT) as the reference.Methods:A set of bladder phantoms were constructed to compare CT and ultrasound measurements with actual injected volumes. Clinical data of 104 pelvic tumor patients who received radiotherapy at the Cancer Hospital, Chinese Academy of Medical Sciences between August and December 2023 were retrospectively analyzed. Portable transabdominal ultrasound was used to obtain the largest bladder cross-section, and the maximum diameters in the left-right (LR), anterior-posterior (AP), and superior-inferior (SI) directions (D LR, D AP, D SI) were measured. The 2D ultrasound volume was calculated as V=0.523 × D LR × D AP × D SI. Full-bladder transverse videos were recorded and processed in Matlab R2016a through frame extraction(60 images), followed by contrast enhancement, edge detection segmentation, cubic spline interpolation, and image smoothing to achieve 3D reconstruction. Paired t-tests, intraclass correlation coefficients (ICC), and Bland-Altman analyses were performed to assess systematic bias and consistency between ultrasound methods and CT. Multivariate linear regression was applied to evaluate the effects of slice thickness, posture, age, and other factors on CT measurements. Results:In the phantom study, deviations of 2D ultrasound and CT from actual injected volumes were (0.73±3.05) ml ( t=-0.48, P=0.667) and (1.52±11.27) ml ( t=0.17, P=0.875), with ICC values>0.999. In the clinical study, mean bladder volumes measured by 3D-reconstructed ultrasound, conventional 2D ultrasound, and CT were (373.5±153.31), (314.89±135.28), (382.82±157.57) ml, respectively. The 3D-reconstructed method showed excellent agreement with CT (ICC=0.98; Bland-Altman mean bias=-9.32 ml, P=0.096), while 2D ultrasound also showed good consistency (ICC=0.91), but significantly underestimated bladder volume (mean bias=-67.93 ml, P<0.001). Subgroup analysis revealed that 2D ultrasound had the best agreement with CT in the medium-volume group (200-500 ml, ICC=0.902), whereas agreement decreased in the small-volume (<200 ml, ICC=0.884) and large-volume (>500 ml, ICC=0.840) groups (all P<0.001). The 3D-reconstructed ultrasound maintained excellent consistency with CT across all subgroups (all ICC>0.95), and the measured bladder volume was not statistically significant. Multivariate regression showed that slice thickness, posture, age, sex, and surgical status had no significant effects on CT measurements. Conclusions:Ultrasound with 3D reconstruction enables accurate bladder volume monitoring through true 3D contour reconstruction, while conventional 2D ultrasound systematically underestimates bladder volume and requires correction.

Objective To investigate the correlation between voice fatigue index(VFI)and the subjective and objective assessment results of voice impairment.Methods Fifty-one patients with voice disorders and 48 normal subjects were selected for VFI assessment and comparison of the differences in scores between the two groups.Sub-jective voice handicap index(VHI)and objective acoustic assessment were performed on the patients with voice dis-orders to analyze the correlation between VFI scores and the results of subjective and objective assessment of voice disorders.Results There was significant difference of the VFI scores between the voice disorder patients and the control group,with the total VFI score,part Ⅰ and part Ⅱ scores higher than those of control group,and the partⅢ score lower than those of the control group(P＜0.05),and there was a strong correlation between the total and part VFI scores and the total and part VHI scores(P＜0.05 or P＜0.01).The VFI part Ⅰ and part Ⅱ scores were regatively correlated with the I-low(P＜0.05),but there was not a significant correlation with the other acoustics parameters and the dysphonia severity index(DSI)(P＞0.05).Conclusion Voice fatigue symptoms were more prominent in the voice-impaired population,and the VFI score was significantly correlated with the subjective voice disorder severity,but the correlation with the objective acoustic parameters was not significant.

Objective To investigate the characteristics of laryngeal diadochokinesis(LDDK)in children with functional articulation disorder(FAD)using different corpus.Methods A total of 23 children with FAD and 21 typically developing(TD)children,aged 4-6,from Shanghai's general kindergartens were recruited.Five types of acoustic parameters were collected:average rate and jitter(％)of LDDK(/?a/,/ha/,/??/,/h?/),the diadochoki-nesis rate(/pataka/),the jitter and shimmer of the vowel/a/,maximum phonation time(MPT).Differences across different corpora of the LDDK were analyzed between the two groups.Results ① Between-group compari-son:the rate of/?a/was significantly lower in FAD children than in TD children(P＜0.05).② Different corpora comparison:the LDDK speed of/?a/-/ha/was significantly different for both groups,/?a/-/??/was significantly different in TD children,and/ha/-/h?/was significantly different in FAD children.The LDDK jitter of/ha/-/h?/was significantly different among FAD children.Conclusion The LDDK of children with FAD is weaker than the TD children,and both groups exhibiting varying abilities across different corpora.
