OBJECTIVE: To compare the registration accuracy of cone beam computed tomography (CBCT) images while registering to virtual craniodentofacial patients based on soft tissue and the dentition registration method. METHODS: Virtual dentofacial patients out of 13 selected participants who needed CBCT scanning were established by impression with a registered-block impression (RBI) based on digital dental images, three-dimensional (3D) facial images and maxillofacial CBCT images. CBCT images were processed in the Mimics software program, establishing the craniofacial virtual patients based on CBCT images (CCTs). Registration between virtual patients from RBI and CCT, using the soft tissue in lower half face (STE) and dentition (DTN) as the reference area, respectively, forming two kinds of virtual craniofacial patients based on digital dental images, 3D facial images and skeletal images of CBCT (hiding the soft tissue and dental casts from CBCT). Three-dimensional deviation analysis was performed in the upper half face and lower half face of facial images from CBCT between two kinds of virtual craniodentofacial patients and compared with 3D facial images from RBI and recorded as root mean square error (RMSE). Paired-t test was used to compare the deviations of RMSEs between the upper and lower half of the face and the upper half of the face of facial images from CCT, respectively, between the two kinds of virtual craniodentofacial patients based on STE and DTN methods. RESULTS: Paired-t tests showed that there was no statistically significant difference between the upper and lower half faces of facial images from CCT between STE and DTN (P>0.05), but the deviation of RMSEs of the upper half face of facial images from CCT in STE was smaller than those in DTN [(1.696±0.420) mm vs. (1.752±0.424) mm, P < 0.01]. CONCLUSION The registration accuracy of CBCT registered in virtual craniodentofacial patients using soft tissue as the reference area was higher.

AIM: To explore the diagnostic value of 18 MHz color Doppler ultrasonography for epiretinal membrane.METHODS: A total of 44 cases(80 eyes)of patients with proposed diagnosis of cataract and vitreous opacity by fundus examination in our hospital between January 2020 and January 2022 were collected, and the affected eyes were examined by optical coherence tomography(OCT)and 18 MHz color Doppler ultrasonography, and the differences in the diagnostic sensitivity, specificity, and accuracy were compared between 18 MHz color Doppler ultrasonography and OCT for the diagnosis of epiretinal membrane.RESULTS: In the 80 eyes detected by 18 MHz color Doppler ultrasonography, 62 had epiretinal membrane and 18 had non epiretinal membrane. Totally 54 eyes were confirmed to have epiretinal membrane by OCT, 13 eyes were not diagnosed with epiretinal membrane, 5 eyes were missed diagnosis, and 8 eyes were misdiagnosed. The diagnostic consistency between 18 MHz color Doppler ultrasonography and OCT was high(Kappa=0.892, P<0.05); the 18 MHz color Doppler ultrasonography detection sensitivity of epiretinal membrane was 92%, specificity was 62%, missed diagnosis rate was 8%, misdiagnosis rate was 38%, and accuracy was 84%; compared with OCT detection, 18 MHz color Doppler ultrasonography detected a lower specificity, correct rate, positive prediction accuracy, negative prediction accuracy, and higher misdiagnosis rate(all P<0.05), and the difference in diagnostic sensitivity compared with leakage rate was not statistically significant(all P>0.05).CONCLUSION: 18 MHz color Doppler ultrasonography has some value in identifying epiretinal membrane lesions and is consistent with OCT testing.

Objective: To investigate the impact of preschool children s aquatic motor skill (AMS) acquisition on their fundamental motor skill (FMS) development and the correlation between AMS and FMS development, so ao to provide a scientific basis for early childhood education and physical education teaching. Methods: From April to June 2024, 60 children, recruited by random sampling from a kindergarten in Taiyuan, were stratified randomly divided into an experimental group ( n =30) and a control group ( n =30). The experimental group were further divided into five classes of six each. They received AMS practice interventions twice weekly, 40 minutes per session, over eight weeks (16 sessions total) at a designated swimming center. The control group maintained their usual routine. Children s FMS and AMS were assessed pre and post intervention using the Test of Gross Motor Development-3rd (TGMD3) and Actual Aquatic Skills Test (AAST), respectively. Before and after test comparisons within and between groups employed t-tests, Wilcoxon signedrank tests, ANCOVA (including ranktransformed ANCOVA), and Cohen s d effect sizes were calculated for standardized mean differences. Spearman rank correlation was used to analyze relationships between FMS and AMS. Results: After the aquatic learning, the experimental group scored significantly higher than the control group on locomotor skills ( F=20.47, P <0.01, η 2=0.26), FMS ( F=4.59, P =0.04, η 2=0.08), and AMS ( F=109.71, P<0.01, η 2=0.79). The experimental groups improvement in locomotor skills 5.0(3.8, 7.3) versus the control group (2.8±2.5) yielded a medium effect size (Cohen s d =0.71); AMS gains in the experimental group [26.0(20.8, 28.0)] versus controls [1.0(0, 2.3)] showed a very large effect size (Cohen s d =4.73) (both P <0.01). Among preschool children, AMS acquisition was positively correlated with locomotor skills ( r =0.39) and overall FMS ( r =0.43)(both P <0.05). Skill specific assessments revealed lower proficiency in headfirst entry (immersion), treading water, and sagittalplane rotation. Conclusion Preschool children s acquisition of AMS has a positive effect on their FMS, with mutual facilitation between the two, especially in locomotor abilities.

The Cronbach's α value of the formal version of the scale was 0. 850, and the Cronbach's α coefficients of the four dimensions were 0.721, 0.772, 0.779, and 0.930, respectively. The CR values of the combined reliabilities of each dimension were all above 0.7. In terms of AVE values, except for the health status dimension was acceptable, the other three dimensions were all above 0.36. The correlation coefficient between the sense of health acquisition and life satisfaction of the elderly was 0.531 ( P<0.01). Conclusion:The developed scale for measuring the sense of gain of the elderly has good reliability and validity, which can be used as an effective tool for measuring the sense of gain of the elderly.

Objective:To investigate the pathways involved in bisphenol S(BPS)and bisphenol F(BPF)induced male reproductive injury by bioinformatics methods and experimental verification.Methods:Bioinformatics analysis was conducted to screen the genes related to male reproductive system diseases associated with BPF and BPS from the Comparative Toxicogenomics Database(CTD).Functional enrichment using Gene Ontology(GO)and Kyoto Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis were performed to predict potential signaling pathways and key genes.Cell counting kit-8(CCK-8)method was used to assess the cell viability in various groups treated with different concentrations of BPS and BPF(1×10-3,1×10-2,1×10-1,1×100,1×101,and 1×102 μmol·L-1).TM3 cells were divided into control group(0.1％DMSO),different doses of BPS groups,and different doses of BPF groups.The cells were treated with 20,40,and 80 μmol·L-1 of BPS and BPF for 72 h,respectively.Real-time fluorescence quantitative PCR(RT-qPCR)and Western blotting method were used to detect the expression levels of key genes mRNA and proteins in various groups.Results:The bioinformatics analysis results revealed that 507 and 447 male systemic disease genes related to BPS and BPF were screened by CTD,respectively.The GO enrichment analysis results showed that the selected genes were primarily enriched in biological processes(BP)such as reproductive system development and reproductive structure development.The KEGG pathway analysis results indicated that these genes were significantly enriched in signaling pathways such as phosphatidylinositol 3-kinase/protein kinase B(PI3K/AKT),hypoxia-inducible factor-1(HIF-1),and cellular senescence(P＜0.001).The CCK-8 method results showed that compared with control group,the cell viabilities in 1× 102 μmol·L-1 BPF and BPS groups were significantly decreased(P＜0.05),while the viabilities of TM3 cells in other groups had no significant changes(P＞0.05).After BPS treatment,compared with control group,the expression levels of PI3K,AKT,hypoxia-inducible factor-1α(HIF-1α),and CREB-binding protein(CBP)mRNA in low,medium,and high doses of BPS groups were decreased(P＜0.05),the expression levels of PI3K protein were decreased(P＜0.05),the expression levels of B-cell lymphoma-2-associated X protein(Bax)protein were increased(P＜0.05),and the expression levels of serine protease inhibitor clade B,member 10(SERPINB10)mRNA were increased(P＜0.01);the expression levels of Bax and intraflagellar transport 80 homolog(IFT80)mRNA in the cells in medium and high doses of BPS groups were increased(P＜0.05);the expression levels of B-cell lymphoma-2(Bcl-2)mRNA and protein in low and high doses of BPS groups were decreased(P＜0.05);the expression levels of additional sex combs like 2(ASXL2)mRNA in low and medium doses of BPS groups were decreased(P＜0.01).After BPF treatment,compared with control group,the expression levels of Bcl-2,HIF-1α,and structural maintenance of chromosomes protein 1B(SMC1B)mRNA in low,medium,and high doses of BPF groups were decreased(P＜0.05),and the expression levels of IFT80 mRNA(P＜0.01)and Bax protein(P＜0.01)were increased;the expression levels of PI3K,AKT,and ring finger protein 130(RNF130)mRNA in low and high doses of BPF groups were decreased(P＜0.05);the expression level of CBP mRNA in medium dose of BPF group was decreased(P＜0.05),while the expression level of RNF130 mRNA was increased(P＜0.05);the expression levels of PI3K and Bcl-2 proteins in high dose of BPF group were decreased(P＜0.05).Conclusion:BPF and BPS may cause cell cytotoxicity and impair male reproductive health through PI3K/AKT and HIF-1 signaling pathways.RNF130 and SMC1B may be important targets for their induction of male reproductive toxicity.

Objective:To explore the influencing factors of the subjective well-being of elderly individuals and improve the accuracy of well-being predictions.Methods:A multi-stage stratified sampling method was conducted in Guangdong province and Guangxi Zhuang autonomous region from August 2019 to October 2020. The health status and subjective well-being of older adults were assessed using a self-administered multidimensional health questionnaire, while overall well-being was evaluated with a single-item 5-point scale. The statistical analysis was performed using R software (version 4.3.2), with analytical methods including χ2 tests, univariate analysis, quantile regression and random forest model. Results:A total of 2 620 participants were recruited, and 70.9% of whom reported feeling happy.The depression symptom score of the elderly was 3.00(1.00, 6.00), emotional status score was (28.26±4.14), activities of daily living (ADL) score was 69.00(52.00, 81.00), and the body mass index(BMI) was (22.68±3.81)kg/m 2.The quantile regression results indicated that marital status (married)(Q 10: β=0.049; Q 50: β=0.014; Q 90: β=0.005) and depressive symptoms (no depression, depressive tendency)(Q 10: β=1.000; Q 50: β=1.000; Q 90: β=0.025) had varying effects on older adults' subjective well-being across three quantiles (Q 10, Q 50, Q 90)(all P<0.05). In contrast, social activity (no social activity)(Q 10: β=-0.072; Q 50: β=-0.011; Q 90: β=-0.006), ADL (severe disability, moderate disability, mild disability)(Q 10: β=-0.103, Q 50: β=-0.006, Q 90: β=-0.048; Q 10: β=-0.063, Q 50: β=-0.012, Q 90: β=-0.005; Q 10: β=-0.078, Q 50: β=-0.016, Q 90: β=-0.009), and emotional status (poor emotion, fair emotion)(Q 10: β=-0.261, Q 50: β=-0.009, Q 90: β=-0.025; Q 10: β=-0.140, Q 50: β=-0.017, Q 90: β=-0.029) had a negative impact on elderly subjective well-being at the three quantile points(all P<0.05). Random forest results indicated that depressive symptoms, ADL, emotional status, household monthly income per capita, BMI, social activity, multimorbidity status, and marital status were the most important determinants of subjective well-being. Conclusion:Depressive symptoms and emotional status have a significant impact on the subjective well-being of older adults. Additionally, ADL, household income per capita, BMI, and social engagement also play important roles in influencing well-being, while the emotional support provided by marriage should not be overlooked.

Objective:To evaluate the safety and efficacy of enhanced recovery after surgery(ERAS) in the perioperative period of congenital choledochal cysts in children.Methods:This is a multicenter prospective randomized controlled study. The clinical data of 273 pediatric congenital choledochal cysts(CCC) patients who underwent surgery at 14 medical centers with complete follow-up data were collected through the medical data analysis platform. Among them, 123 cases in ERAS group were managed perioperatively in strict accordance with ERAS mode, and 150 cases in conventional group were managed according to traditional mode. The length of hospital stay,time to first farting, time to complete feeding, the incidence of complications, cost and readmission rate within 30 days,stress indexes and liver function were compared between the two groups.Results:Compared with the conventional group, median time to start farting (2.0 d vs. 3.0 d, P<0.001), median time to complete feeding (5.0 d vs. 7.0 d, P<0.001), median postoperative hospitalization time (6.0 d vs. 9.0 d, P<0.001),the median total length of stay(13.0 d vs. 15.0 d, P<0.001) were shorter,the median hospitalization cost (37,000 yuan vs.43,000 yuan P<0.001) was lower, and stress indexes recovered quickly. The incidence of postoperative hospital stay and readimission rate within 30 d were not statistically different between the two groups. Conclusion:It is safe and feasible to implement ERAS for children with CCC in the perioperative period, which can reduce stress response, speed up recovery,and save medical costs.

Objective:To investigate the clinical efficacy of tacrolimus combined with Jisheng Shenqi pills and Sijunzi decoction in treating spleen-kidney deficiency type lupus nephritis in patients. Methods:A randomized controlled study was conducted on 82 patients with spleen-kidney deficiency type lupus nephritis admitted to Weinan Central Hospital from January 2019 to December 2023. The patients were divided into a control group ( n = 41) and an observation group ( n = 41) using the coin flip method. The control group was treated with tacrolimus, while the observation group received Jisheng Shenqi pills and Sijunzi decoction in addition to the control group's treatment. All patients were treated for 2 months. The clinical efficacy, traditional Chinese medicine (TCM) syndrome scores, systemic lupus erythematosus disease activity index (SLE-DAI) scores, chronicity index (SLE-CI) scores, renal function (cystatin C, blood urea nitrogen, serum creatinine), high-sensitivity C-reactive protein, transforming growth factor β 1, procalcitonin, silent information regulator 4 (SIRT4) levels, and adverse reactions (gastrointestinal discomfort, dizziness, rash, liver function abnormalities) were compared between the two groups. Results:The total effective rate of clinical treatment in the observation group was significantly higher than that in the control group [95.12% (39/41)] vs. [80.49% (33/41), χ2 = 4.10, P < 0.05). After treatment, the TCM syndrome scores, SLE-DAI scores, and SLE-CI scores in the observation group were (4.24 ± 0.96) points, (9.04 ± 1.40) points, (1.22 ± 0.17) points, respectively, which were significantly lower than those in the control group [(8.13 ± 1.06) points, (12.78 ± 1.82) points, (1.37 ± 0.19) points, t = 17.41, 10.42, 3.76, all P < 0.05]. The levels of cystatin C, blood urea nitrogen, and serum creatinine in the observation group were (1.49 ± 0.42) mg/L, (5.20 ± 1.30) mmol/L, (93.27 ± 5.22) μmol/L, respectively, which were significantly lower than those in the control group [(2.16 ± 0.46) mg/L, (6.26 ± 1.27) mmol/L, (103.29 ± 5.07) μmol/L, t = 6.88, 3.73, 8.81, all P < 0.05]. The levels of high-sensitivity C-reactive protein, transforming growth factor β 1, and procalcitonin in the observation group were (3.24 ± 0.87) mg/L, (32.27 ± 6.57) μg/L, (14.11 ± 2.34) μg/L, respectively, which were significantly lower than those in the control group [(4.48 ± 0.81) mg/L, (40.34 ± 7.52) μg/L, (18.26 ± 2.79) μg/L, t = 6.67, 5.17, 7.29, all P < 0.05], while the level of SIRT4 was significantly higher in the observation group [(0.47 ± 0.06) mg/L] compared with the control group [(0.37 ± 0.04) mg/L, t = 8.87, P < 0.05]. The incidence of adverse reactions in the observation group [4.87% (2/41)] was slightly, but not significantly, lower than that in the control group [14.63% (6/41), χ2 = 2.21, P > =0.05]. Conclusion:Tacrolimus combined with Jisheng Shenqi pills and Sijunzi decoction in treating spleen-kidney deficiency type lupus nephritis can significantly improve clinical efficacy, reduce TCM syndrome scores, SLE-DAI scores, and SLE-CI scores, improve renal function, alleviate inflammation, and has good safety.
