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.

Objective:The incidence of prostate cancer is increasing every year,and precision diagnosis and treatment can help reduce unnecessary prostate punctures for prostate cancer patients in the gray area.This study aims to investigate the diagnostic value of 18F-prostate specific membrane antigen(PSMA)imaging combined with prostate specific antigen(PSA)-derived indicators for gray zone prostate cancer. Methods:A total of 107 patients who underwent 18F-PSMA PET/CT imaging for suspicious prostate cancer with tPSA of 4 to 10 μg/L(PSA gray zone)in a hospital were retrospectively included,and were divided into a prostate cancer group and a non-prostate cancer group based on pathological findings.Patients underwent PSA testing,18F-PSMA,and abdominal ultrasound,and age,tPSA,fPSA,f/tPSA,prostate volume,PSA density(PSAD),maximum standardized uptake value(SUVmax),and molecular imaging prostate specific membrane antigen(miPSMA)score were compared between the 2 groups.Multivariate logistic regression was used to analyze the influencing factors the diagnosis of gray zone prostate cancer.Receiver operating characteristic(ROC)curves were constructed to evaluate the efficacy of PSAD and SUVmax alone and in combination in diagnosing gray zone prostate cancer. Results:The volume of the prostate cancer group[42.00(34.00,58.00)cm3 vs 49.00(41.27,60.41)cm3]was smaller than that of the non-prostate cancer group(Z=-2.376,P=0.017),and the PSAD[(0.18±0.06)μg/(L·cm3)vs 0.15±0.05 μg/(L·cm3)]and SUVmax[18.63(8.03,28.57)vs 9.33(5.90,13.52)]were higher than those in the non-prostate cancer group(both P<0.05).The percentage of miPSMA score≥2 in the prostate cancer group was higher than that in the non-prostate cancer group(χ2=40.987,P<0.001).PSAD(OR= 22.154,95%CI 1.430 to 873.751,P=0.042)and SUVmax(OR=1.301,95%CI 1.034 to 1.678,P=0.009)were independent influential factors for the diagnosis of prostate cancer in the gray zone.The optimal cut-off values of PSAD and SUVmax were 0.22 μg/(L·cm3)and 8.02,respectively,and the AUCs for the diagnosis of prostate cancer in the gray zone alone and in combination were 0.628(95%CI 0.530 to 0.720,P<0.05)and 0.806(95%CI 0.718 to 0.876,P<0.05),0.847(95%CI 0.765 to 0.910,P<0.05),with sensitivities of 41.03%,76.92%,and 74.36%and specificities of 79.41%,89.71%,and 92.65%,respectively. Conclusion:PSAD and SUVmax are increased in patients with gray zone prostate cancer,and the combination of PSAD and SUVmax is of high value in diagnosing gray zone prostate cancer.

The methylation of N6-methyladenosine(m6A)is an important gene expression regulation mechanism in eukaryotes.It is mainly regulated by three types of regulators:writers,erasers and readers.With the development of high-throughput sequencing technology and bioinformatics,various methods have been developed to detect and analyze m6A methylation sites.A growing body of research has shown that m6A methylation plays an important role in the occurrence and development of urological tumors,including tumor proliferation,invasion and metastasis.However,the molecular mechanism and role of m6A in different types of urological tumors have not been fully elucidated.This article reviews the main regulatory mechanism of m6A methylation modification as well as the research progress,the prognostic value and the therapeutic resistance of m6A methylation modification in urological tumors.

The present study analyzed the efficacy evaluation indexes of the randomized controlled trials(RCTs) of Chinese medi-cine in the treatment of rheumatic heart disease to lay the foundation for the construction of the corresponding core outcome index set. Clinical RCTs with a definite diagnosis of rheumatic heart disease were retrieved from CNKI, Wanfang, VIP, Sino Med, Pub Med, EMbase, and Cochrane Library from January 1, 2010, to December 31, 2020. Thirty-five RCTs were included, involving 3 314 patients and 41 efficacy evaluation indexes, which covered seven domains [traditional Chinese medicine(TCM) symptoms/syndromes, symp-toms/signs, physical and chemical examination, quality of life, long-term prognosis, economic evaluation, and safety events]. Physi-cal and chemical examination(56. 91%) and symptoms/signs(29. 27%) were the more frequently applied. The number of indexes used in a single trial ranged from 1 to 15, with an average of 4. The measurement time points of the top five indexes in the frequency of use were as follows: total response rate was reported at five measurement time points, ranging from 14 days to 6 months; left ventri-cular ejection fraction was measured at eight time points ranging from 5 days to 6 months; left ventricular end systolic diameter was measured at six time points, ranging from 5 days to 6 months; interleukin-2(IL-2) and tumor necrosis factor-α(TNF-α) were repor-ted 28 days after treatment. At present, there are many problems in the efficacy outcome indexes of RCTs in the treatment of rheumatic heart disease with TCM, such as large difference in quantity, unclear primary and secondary indexes, unreasonable selection of " surro-gate indexes", insufficient attention to long-term prognostic indexes and safety event indexes, non-standard application of composite in-dexes, long measurement period, and lack of TCM characteristics. It is urgent to establish the core outcome set for TCM treatment of rheumatic heart disease.

OBJECTIVES: To study the clinical features and fibroblast growth factor receptor 3 (FGFR3) gene mutations of children with achondroplasia (ACH) through an analysis of 17 cases. METHODS: A retrospective analysis was performed on the clinical data and FGFR3 gene detection results of 17 children with ACH who were diagnosed from January 2009 to October 2021. RESULTS: Of the 17 children with ACH, common clinical manifestations included disproportionate short stature (100%, 17/17), macrocephaly (100%, 17/17), trident hand (82%, 14/17), and genu varum (88%, 15/17). The common imaging findings were rhizomelic shortening of the long bones (100%, 17/17) and narrowing of the lumbar intervertebral space (88%, 15/17). Major complications included skeletal dysplasia (100%, 17/17), middle ear dysfunction (82%, 14/17), motor/language developmental delay (88%, 15/17), chronic pain (59%, 10/17), sleep apnea (53%, 9/17), obesity (41%, 7/17), foramen magnum stenosis (35%, 6/17), and hydrocephalus (24%, 4/17). All 17 children (100%) had FGFR3 mutations, among whom 13 had c.1138G>A hotspot mutations of the FGFR3 gene, 2 had c.1138G>C mutations of the FGFR3 gene, and 2 had unreported mutations, with c.1252C>T mutations of the FGFR3 gene in one child and c.445+2_445+5delTAGG mutations of the FGFR3 gene in the other child. CONCLUSIONS This study identifies the unreported mutation sites of the FGFR3 gene, which extends the gene mutation spectrum of ACH. ACH is a progressive disease requiring lifelong management through multidisciplinary collaboration.

Objective: To investigate the effect of pesticides and herbicides on lipid metabolism. Methods: In November 2020, Based on the data of the national health and Nutrition Survey (NHANES) (2011-2014) , select the population aged 20~65 who have demographic information, pesticide use and data of four lipid metabolism indicators [total cholesterol (TC) , triglyceride (TG) , high density lipoprotein cholesterol (HDLC) and low density lipoprotein cholesterol (LDLC) ] (n=3039) . The subjects were divided into insecticide group (320 people) and non insecticide group (2719) according to the use of insecticides, and herbicide group (156 people) and non herbicide group according to the use of herbicides. Results: Among the 3039 subjects, the males and female were 1509 (49.7%) and 1530 (50.3%) respectively. The males age was (39.7±12.0) years and the females age was (40.2±12.0) years The concentration of HDLC in the NHANES (55.4±15.0) mg/dl was lower than that of (58.2±14.2) mg/dL in the non herbicide group (P<0.05) (b=-0.044, P<0.05) . The results showed that the use of herbicides was related to the decrease of HDLC and the increase of LDLC and LDLC/HDLC in female population (b=-0.050, 0.062, 0.067, all P<0.05) . Conclusion: Herbicide exposure can cause the change of lipid metabolism, and the effect on female population is more obvious.

Work-related musculoskeletal disorders (WMSDs) refer to musculoskeletal disorders caused by work or work as the main cause, which are characterized by high prevalence and heavy burden of disease as a global problem. The classification and catalog of occupational diseases is of great significance for guiding the prevention and control of occupational diseases and safeguarding the rights and interests of workers. The types of WMSDs included in the list of occupational diseases vary greatly from country to country, and the regulations on specific pathogenic factors are also inconsistent. By sorting out and analyzing the lists and characteristics of WMSDs at home and abroad, and using the International Statistical Classification of Diseases and Related Health Problems (ICD-10) in occupational health to standardize of WMSDs in various countries, which would lay the foundation for future multi-country WMSDs occupational health registration and disease burden research, and provide a reference for China to revise the WMSDs list.

In order to reveal the molecular mechanism of blue labeled genic male sterility (BM-type GMS) and utilize the heterosis of BM-type GMS, we used the anthers of white-seed plants WS (sterile) and light blue seed plants WF (normal fertility) as experimental materials to analyze the differences in gene expression between them by transcriptome technology. And we also verified the genes expressed in anthocyanin synthesis in this study. Compared with WF, a total of 2352 differentially expressed genes were detected in WS. According to GO functional annotation, these genes could be divided into 3 categories and 43 subgroups. They are mainly involved in biosynthesis, phenylpropane metabolism, L-phenylalanine catabolism, membrane components, plasma membrane, cytoplasm, ATP binding, protein serine/threonine kinase activity, etc. KEGG pathway analysis showed that there were 159 genes enriched in the phenylpropanoid biosynthesis pathway, followed by the phenylalanine pathway, including 136 differentially expressed genes. Other genes are also involved a variety of amino acid metabolism, purine metabolism, pyrimidine metabolism and sugar metabolism pathway. Related to anthocyanin metabolism, several structural genes of key enzymes were differentially expressed, and most of them were up-regulated in WF, while only Flavanone 3-hydroxylase (F3H) and colorless anthocyanin dioxygenase (ANS) were down-regulated. Quantitative real-time PCR showed that the expression of 10 genes related to anthocyanin metabolism had the same trend as that in transcriptome sequencing data. Sequence homology analysis showed that the two selected transcription factors (DN48762c2g1 and DN25944c0g1) are clustered into the same cluster as the transcription factors regulating anthocyanin biosynthesis in maize, rice and Arabidopsis thaliana, which might be candidate genes for the blue aleurone layer of light blue seed plants in wheat. And fluorescence quantitative analysis showed that the expression level of DN48762c2g1 and DN25944c0g1 in WF was significantly higher than that in WS. In conclusion, the genes related to the anthocyanin biosynthesis pathway are not only related to the blue grain trait, but also may be involved in the anther abortion of BM-type GMS.

Objective:To evaluate the clinical efficacy of Xuanfei Huazhuo prescription in the treatment of coronavirus disease-2019 (COVID-19). Method:A total of 40 patients with COVID-19 were selected and treated with Xuanfei Huazhuo prescription. The changes of body temperature, clinical symptoms, computed tomography (CT), blood routine and biochemical indexes were observed before and after treatment. Result:The 40 patients included 15 males and 25 females, with a male to female ratio of 1∶1.7. They were aged between 20-94 years old, with the average age of （43.9±16.3） years old. The course of disease was 8-23 days, with the average of （14±4.4） days. Compared with before administration, the patients' clinical symptoms, such as cough, fever, sputum, diarrhea, loss of appetite and fatigue, were all improved (P<0.05). Before treatment the traditional Chinese medicine (TCM) syndromes of patients were mainly cold dampness lung (57.5%) and cold dampness Lung (42.5%), and the tongue coating was mainly white greasy coating (52.9%). After adjuvant treatment with Xuanfei Huazhuo prescription, the fever removal time was (2.48±2.56) days; white blood cell (WBC), lymphocyte percentage (LYM%), neutrophil percentage (NEUT%), absolute value of lymphocytes (LYM #) indexes of C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), total bilirubin (TBIL), ratio of glutamic oxaloacetic transaminase to glutamic pyruvic transaminase (AST/ALT) and lactate dehydrogenase (LDH) were basically restored to the normal range (P<0.05) compared with before administration. After adjuvant treatment with Xuanfei Huazhuo prescription, the results of three pharyngeal test virus nucleic acid tests were negative, and the lung CT showed that infected lesions were absorbed and all met the discharge criteria. All 40 patients met the discharge criteria and were all cured and discharged, with a cure rate of 100%. There has been no case of recurrence with a positive result of nucleic acid detection so far. The score of symptom and clinical index of patients after administration was （1.62±1.90）, which was significantly lower than that before administration (7.65±4.08, P<0.05). Conclusion:In the adjuvant treatment of COVID-19, Xuanfei Huazhuo prescription can reduce body temperature, promote the absorption of pulmonary inflammation, and improve clinical symptoms, such as fever and cough.
