Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

The WRKYs are a group of plant-specific transcription factors that play important roles in defense responses. In this study, we silenced 2 GmWRKY33B homologous genes using a bean pod mosaic virus (BPMV) vector carrying a single fragment from the conserved region of the GmWRKY33B genes. Silencing GmWRKY33B did not result in morphological changes. However, significantly reduced resistances to Pseudomonas syringae pv. glycinea (Psg) and soybean mosaic virus (SMV) were observed in the GmWRKY33B-silenced plants, indicating a positive role of the GmWRKY33B genes in disease resistance. Kinase assay showed that silencing the GmWRKY33B genes significantly reduced the activation of GmMPK6, but not GmMPK3, in response to flg22 treatment. Reverse transcriptase PCR (RT-PCR) analysis of the genes encoding prenyltransferases (PTs), which are the key enzymes in the biosynthesis of glyceollin, showed that the Psg-induced expression of these genes was significantly reduced in the GmWRKY33B-silenced plants compared with the BPMV-0 empty vector plants, which correlated with the presence of the W-boxes in the promoter regions of these genes. Taken together, our results suggest that GmWRKY33Bs are involved in soybean immunity through regulating the activation of the kinase activity of GmMPK6 as well as through regulating the expression of the key genes encoding the biosynthesis of glyceollins.

Objective:To investigate the mechanism of Yunshi Ganmao Heji against respiratory syncytial virus (RSV) infection based on network pharmacology and in vivo experiments. Methods:Network pharmacological prediction: Several databases including TCMSP and GeneCards were used to predict the active ingredients and targets of Yunshi Ganmao Heji in the intervention of RSV infection. Cytoscape 3.2.1 software was used to construct the traditional Chinese medicine component-disease target network diagram. The interactions between proteins were analyzed by STRING database. GO functional enrichment analysis and KEGG pathway enrichment analysis were performed using Metascape database. Molecular docking technology was used to verify the results of network pharmacology. Experimental verification of Yunshi Ganmao Heji for the intervention of RSV infection: A mouse model of RSV infection was established through intranasal infection. After the administration of Yunshi Ganmao Heji, blood routine test results, lung indexes and pathological changes in lung tissue were analyzed. Peripheral blood T cell subsets were detected by flow cytometry. The levels of TNF-α, IL-6 and IL-1β in serum were detected by ELISA. RT-PCR was used to detect the relative expression of TLR4, NF-κB and RSV-N gene at mRNA level in lung tissues.Results:A total of 41 active ingredients of Yunshi Ganmao Heji and 111 drug targets for RSV infection were obtained. Besides, 167 signaling pathways mainly including PI3K/AKT, MAPK and Toll-like receptor signaling pathways were obtained. Molecular docking results showed that the binding energies of luteotin, kaempferol and quercetin, three active ingredients of Yunshi Ganmao Heji, with RSV-G, RSV-F, PI3K, AKT1 and Bcl-2 were less than 0 kcal/mol. In vivo experiment results showed that compared with RSV group, the counts of white blood cells and lymphocytes increased and the lung index decreased in high-dose Yunshi Ganmao Heji group, with statistically significant difference ( P<0.05). HE staining showed pulmonary hyperplasia, thickened alveolar wall and inflammatory cell infiltration in interstitium in RSV group. Alveoli in ribavirin group as well as low-dose, medium-dose and high-dose Yunshi Ganmao Heji groups tended to be of uniform size, and the alveolar walls was roughly uniform in thickness. Compared with RSV group, the low-dose, medium-dose and high-dose Yunshi Ganmao Heji groups showed significantly increased numbers of CD3 +, CD4 + and CD8 + T lymphocytes, decreased CD4 + /CD8 + T cell ratio, lower levels of TNF-α, IL-6, IL-1β in serum, and reduced viral load and inhibited expression of TLR4 and NF-κB at mRNA level in lung tissues ( P<0.05). Conclusions:Yunshi Ganmao Heji can regulate RSV infection by targeting multiple targets and pathways with several active ingredients. Its main functions are to alleviate pathological injury in lung tissues and reduce inflammatory response, and the possible mechanism underlying the antiviral functions may be related to its inhibitory effect on the activation of TLR4/NF-κB pathway.

Objective:To investigate the correlation of hepatocellular carcinoma (HCC) classified by contrast-enhanced ultrasound (CEUS) Liver Imaging Data and Report System (LI-RADS) with differentiation degree and Ki-67 index.Methods:A multicenter, retrospective study was conducted.The clinical and CEUS imaging data of 208 patients with 208 HCC lesions from December 2017 to December 2020 in China CEUS database were included and analyzed. According to the CEUS LI-RADS version 2017 proposed by the American College of Radiology, the HCC was classified. The diagnosis and pathological information of all lesions were confirmed by pathology. The differentiation degree of HCC and the distribution of Ki-67 index in different LI-RADS categories were evaluated, and their correlation was analyzed.Results:The degree of differentiation and Ki-67 index among HCC of different CEUS LI-RADS were statistically significant ( P<0.001, P=0.009). LI-RADS M HCC was more likely to be poorly differentiated and showed a higher Ki-67 index. The category of LI-RADS was positively correlated with the degree of tumor differentiation (tau-b=-0.250, P<0.001) and the Ki-67 index (tau-b=0.178, P=0.002), that is, the higher the category of LI-RADS, the lower differentiation degree and the higher the Ki-67. Conclusions:The CEUS LI-RADS classification of HCC is correlating with the degree of differentiation and Ki-67 index.

Objective:To investigate the clinical and genetic features of patients with ACTL6B gene variations, and to report novel pathogenic variations of the ACTL6B gene, summarize the clinical phenotypes and genotypes of the gene. Methods:The clinical phenotypes and genotypes of a infant with developmental epileptic encephalopathy carrying the ACTL6B gene variations, who visited the Department of Neurology, Capital Institute of Pediatrics-Peking University Teaching Hospital on March 12, 2021 were analyzed. The phenotypes and genotypes of patients carrying the ACTL6B gene variations reported in the literature were also summarized and analyzed. Results:The proband was a 2-month-old male presented with convulsive seizures, development delay, dystonia, and cherry erythema in the fundus. The whole exome sequencing of his family showed that he carried compound heterozygous variation c.937-2A>G(p.?), c.11delG(p.G4Afs *86) which derived from his parents respectively. These 2 genotypes had not been reported. A total of 42 cases with ACTL6B gene variation were reported in the literature and in this study. There were 11 de novo heterozygous variations and 31 bi-allelic variations inherited from the parents (24 homozygous and 7 compound heterozygous). Individuals with variations tended to have epilepsy, development delay, ambulation disability, speech disability and dystonia. Minor facial dysmorphisms and autism spectrum disorder also can be seen. Conclusion:This paper summarizes the clinical and genetic features of patients with ACTL6B gene variations, reports 2 novel variations and a novel combination of this gene with cherry erythema in the fundus.

Objective:To explore the changing characteristics of early warning information ability in children with transient tic disorder(TTD).Methods:A total of 32 children with TTD(TTD group) diagnosed and treated at Changzhou Children's Hospital from 2018 to 2022 and 36 healthy control children(HC group) recruited from ordinary primary schools in Changzhou city were tested with CPT-Go/Nogo task and their behavioral data and cue/uncue-N2, P3b and CNV components of event related potential(ERP) were analyzed and compared by SPSS 25.0 software.Results:(1)Comparison of behavioral data: there was no statistical difference in the correct number(37(34, 39) vs 38(37, 40)), false number(1(0, 2) vs 1(0, 2))and correct reaction time((511.27±99.27)ms vs(504.88±92.23)ms)between TTD and HC group(all P>0.05). (2) Comparison of ERP components: in the HC group, the amplitudes of cue-CNV were higher than those in uncue-CNV in lead Cz((-4.61±4.67)μV vs(-1.07±3.20)μV)and Pz((-4.17±3.74)μV vs(-1.79±3.49)μV) and the differences were statistically significant(both P<0.01). The amplitude of cue-P3b in lead Pz were higher than that in uncue-P3b((9.13±4.99)μV vs(6.12±6.24)μV) and the difference was statistically significant( P<0.01). Compare with HC group((-4.12±4.25)μV, (-4.61±4.67)μV, (9.13±4.99)μV), the amplitudes of uncue-N2, cue-CNV and cue-P3b in TTD group((-1.29±4.48)μV, (-2.03±3.19)μV, (6.59±3.41)μV) were respectively lower, and the differences were statistically significant(all P<0.05). Conclusion:Children with TTD may have dysfunction in conflict monitoring, attention allocation, and maintaining alertness when processing early warning information, but there may be corresponding compensation mechanisms for brain function.

Objective:To compare the characteristics of MSM with different types of primary sexual partners and to analyze the factors associated with MSM not being tested for HIV in the last six months.Methods:MSM were recruited in nine cities of Shandong Province from April to July 2021, and face-to-face questionnaires were conducted to collect information on sociodemographic characteristics, high-risk behaviors, and HIV testing of MSM. Blood samples were taken for serological tests of HIV and syphilis antibodies.Results:A total of 3 008 men who had anal sex with men in the last six months were divided into three groups according to the type of primary sexual partner in the last six months: the fixed sexual partner group (36.83%, 1 108/3 008), the commercial sexual partner group (3.06%, 92/3 008), and casual sexual partner group (60.11%, 1 808/3 008). There were statistically significant differences in the distribution of age, local residence time, education level, the primary place to find male sexual partners, use of new-type drugs in the last six months, consistent condom use every time during same-sex anal sex in the last six months, group sex in the last six months, no HIV testing in the last six months, having had a sexually transmitted disease in the last year, receiving peer education in the last year, and frequency of syphilis testing in the last year among different groups ( P<0.05). Multivariable logistic regression analysis showed that related factors of not being tested for HIV in the last six months in MSM were those aged less than 30 years old (a OR=1.39, 95% CI: 1.06-1.83), married/cohabiting (a OR=1.74, 95% CI: 1.39-2.16), high school education or less (a OR=1.39, 95% CI: 1.15-1.67), had not used new-type drugs in the last six months (a OR=2.27, 95% CI: 1.89-2.71), had not received peer education in the last year (a OR=1.59, 95% CI: 1.28-1.98), had never been tested for syphilis (a OR=11.30, 95% CI: 8.15-15.66), had not been tested in the last year but had been previously tested for syphilis (a OR=5.65, 95% CI: 4.19-7.62), the type of primary sexual partner in the last six months being a commercial sexual partner (a OR=1.80, 95% CI: 1.01-3.20), and the type of primary sexual partner in the last six months being a casual sexual partner (a OR=1.50, 95% CI: 1.26-1.80). Conclusions:The characteristics of MSM with different types of primary sexual partners are different, and the proportion of HIV testing still needs to be improved. In the future, we should make full use of the Internet and peer education to expand the coverage of HIV testing for MSM, targeting the characteristics of MSM with different types of primary sexual partners.

Objective:To evaluate the value of whole exome sequencing (WES) in prenatal clinical application.Methods:A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed.Results:Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results.Conclusions:WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.
