Objective: The clinical data involving pediatric dental trauma and the features of dental trauma in children were summarized to provide a reference for the treatment and prevention of dental trauma. Methods: A retrospective analysis was performed on 644 children with dental trauma who were admitted to the Department of Children s Stomatology, Stomatology Hospital of Xiamen Medical College from January to December 2022. Descriptive methods were used to analyze the general demographic characteristics of the children and clinical features of dental trauma. Results: The characteristics of the children with dental trauma were as follows: male-to-female ratio, 2.16∶1; mean age, (6.73±3.42) years; most frequently affected age groups, 2-4 and 7-9 years (26.09%, 33.85%); most frequent season for dental trauma, spring (27.61%) and autumn (28.55%); least common season for dental trauma, summer(18.88%); most frequent time of day for dental trauma, evening (51.47%); least common time of day for dental trauma, morning (2.68%); >24 h elapsed from dental trauma-to-treatment (42.08%); most common type of injuries; simple tooth hard tissue and pulp injury in permanent teeth(65.25%) and simple periodontal tissue injury of primary teeth( 53.35 %); most likely teeth involved, maxillary central incisors (80.10%); and number of affected teeth, 1-2. Conclusions The incidence of dental trauma in children has common features, but most children do not see a dentist timely after dental trauma occurs. Educating parents of children with dental trauma should be encouraged to reduce the incidence of dental injury.

Objective To screen the prevalence and related risk factors of minor hallucinations(MH)in newly diagnosed Parkinson's disease(PD).Methods From November 2018 to December 2022,274 newly diagnosed patients with untreated PD were enrolled in the PD Clinic of Brain Hospital Affiliated to Nanjing Medical University.According to the score of item 2 of the unified PD rating scale Ⅰ(UPDRSⅠ),the PD patients with MH were selected(MH group,score≥2).The patients matched in age,sex,education and course of disease level were screened in non-MH PD patients(NMH group,score = 0).Cognitive function,depressive symptoms,anxiety symptoms,sleep quality,non-motor symptoms,rapid eye movement sleep disorder(RBD)symptoms,activities of daily life,motor function and disease severity were evaluated with appropriate scales.The differences between two groups were compared,and the risk factors of MH in PD patients were analyzed by univariate and multivariate progressive Logistic regression.Results Among the 274 newly diagnosed PD patients,11 cases(4.01%)had MH.Compared with those in NMH group(22 cases),MH group had higher Hamilton depression scale(HAMD)scores,higher Hamilton anxiety scale(HAMA)scores,higher PD non motor symptoms(PDNMS)scores and higher RBD scores(all P＜0.05).Univariate Logistic regression analysis showed that high HAMD scores,high HAMA scores,high PDNMS scores and high RBD scores were risk factors for MH in PD patients(all P＜0.05).Multivariate Logistic regression analysis showed that high HAMD score(OR =1.182,95%CI:1.004-1.392,P =0.045)and high RBD score(OR =4.448,95%CI:1.066-18.557,P =0.041)were independent risk factors for MH in PD patients.Conclusions MH may occur in newly diagnosed PD patients with probability.Depression and RBD are independent risk factors for MH in PD patients.Attention should be paid to screening patients like this and early intervention measures should be taken.

Drug therapy is a common method to cure diseases and relieve symptoms.The value of patient-reported outcome(PRO)in evaluating the effect of drug therapy has been increasingly paid attention.The PRO scale is a standardized questionnaire,which can scientifically evaluate the experiences and subjective effects of drug use from a patient-centered perspective,and help patients and clinicians make more reasonable medication decisions.By reviewing and sorting out relevant global literature,this paper found that the content of the PRO scales relevant to drug therapy focused on five fields:"medication satisfaction""medication adherence""drug treatment burden""medication-related quality of life"and"adverse drug reactions".This paper described the basic information,measurement characteristics and application of common scales in recent years respectively,and summarized and analyzed the problems and enlightenment of scale development,aiming to provide theoretical reference for the selection,application and development of PRO scales.

Objective:To investigate the correlation between gender, age, blood collection time, season and changes in cTnT concentration.Methods:In this study, 3548 patients (non-cardiovascular diseases) in Zhongshan Hospital of Fudan University were selected from 1 January to 31 December 2019. The basic data of the patients were collected, including gender, age, time of blood collection, medical history, clinical diagnosis, and results of cTnT testing. 1 840 males and 1 708 females were finally enrolled, with an age distribution of 65 (53, 75) years. The distribution of the data was assessed using the Kolmogorov-Smirnov (K-S) test, where non-normally distributed data were expressed as M( Q1, Q3). The Mann-Whitney U-test was used to compare cTnT concentrations between men and women, and to analyse the influence of gender on cTnT results. The Kruskal-Wallis test was used to compare cTnT levels between gender groups, to analyse the correlation between different times of blood collection, seasons, and other factors and cTnT concentrations. Result:cTnT concentrations increased with age in both males and females over the age of 60 years. cTnT levels were highest in individuals over the age of 90 years (0.028 ng/ml in males and 0.018 ng/ml in females). cTnT levels were higher in males (0.012 ng/ml) than in females (0.009 ng/ml) in all age groups ( H=6.340, P<0.01). The concentrations of cTnT varied at different time points of blood collection. In both males and females, cTnT concentrations reached a maximum at 8:00 and 13:00 (0.013 ng/ml and 0.012 ng/ml, respectively). Analysis of the physiological effect of season on cTnT secretion showed that cTnT levels were generally higher in spring and winter(0.012 ng/ml) than in summer and autumn(0.010 ng/ml). Conclusions:cTnT concentration is influenced by gender, age, time of blood collection and season. When analysing cTnT results in clinical practice, the gender and age of the individual should be taken into account, as well as the time point of blood collection and seasonal factors.

Objective:To investigate the efficacy of sacubitril/valsartan in the treatment of cancer therapy-related cardiac dysfunction(CTRCD).Methods:A comprehensive analysis of all the literature on sacubitril/valsartan therapy for CTRCD published in Pubmed,Web of Science,Cochrane Library,Medline,and Embase from the inception of the database up to March 2023 was conducted,summarizing the tim-ing of drug administration,dosage,and efficacy,and further systematically summarizing the clinical studies on the use of the drug for the prevention of CTRCD.Results:After 3-12 months of treatment with sacubitril/valsartan for CTRCD,NYHA in cancer patients improved from grade Ⅱ-Ⅳ to grade Ⅰ-Ⅱ,LVEF increased by 3.0%to 37.0%,and NT-proBNP decreased by 280.0-65 498.0 pg/mL.Conclusions:The sacu-bitril/valsartan demonstrates efficacy in managing CTRCD and holds significant clinical utility in enhancing LVEF,GLS,and other patient indic-ators,thereby enabling the continuation of anti-tumor therapy and prolonging survival for cancer patients.

Tuberculosis is a worldwide chronic infectious disease that has become a serious threat to human health.Early diagnosis,drug resistance screening and control of disease transmission are key aspects of TB prevention and treatment.However,existing diagnostic techniques and drug sensitivity tests are time-consu-ming and difficult to realize the purpose of early diagnosis and drug resistance screening,which greatly limits the control of disease transmission.Digital polymerase chain reaction(dPCR)is the third generation of poly-merase chain reaction(PCR),which is a quantitative nucleic acid assay with high sensitivity and no calibration curve.This article provides an overview of the principles of dPCR and its application in tuberculosis diagnosis,drug resistance screening and transmission monitoring,compares dPCR with other tuberculosis detection methods,and looks at the challenges and future prospects of dPCR in clinical tuberculosis laboratory applica-tions.

Objective: To investigate the transcriptomic changes in primary human oral keratinocytes (pHOKs) after coculture with Prevotella melaninogenica (P.m) and to verify the changes in human oral keratinocyte (HOK) cell lines. Methods: pHOK was isolated and cocultured with P.m for 0, 4 and 24 h. Total RNA was extracted, a gene library was constructed, transcriptional sequencing was performed, differentially expressed genes (DEGs) were analyzed, gene ontology (GO) pathway analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis were performed, and the validation of DEGs was performed by qRT-PCR and Western Blot in the HOK and P.m coculture cell model. Results : 1 788 DEGs were detected between the 4 h group and control group, including upregulated DEGs such as lymphocyte cytosolic protein 1(LCP1), keratin 7 (KRT7) and Cilia and flagella associated protein 251(CFAP251) and downregulated DEGs such as FERM, ARH/RhoGEF and Pleckstrin domain protein 1 (FARP1), WW domain containing transcription regulator 1(WWTR1) and Discoidin, CUB and LCCL domain-containing protein 2 (DCBLD2). 1 832 DEGs were detected between the 24 h group and control group, including upregulated DEGs such as LCP1, complement C1s(C1S), kynureninase (KYNU) and downregulated DEGs such as phosphoserine aminotransferase 1 (PSAT1), FARP1 and FKBP prolyl isomerase 10 (FKBP10). There were 1 090 common differentially expressed genes (cDEGs) in the 4 h and 24 h groups, including LCP1, KYNU and long intergenic nonprotein coding RNA 958 (LINC00958). The GO pathways were mainly enriched in response to lipopolysaccharide and the molecules of bacterial origin and apical part of the cell. KEGG pathway analysis revealed enrichment in the interleukin-17 (IL-17) signaling pathway, tumor necrosis factor (TNF) signaling pathway, Toll-like receptor (TLR) pathway, etc. We verified the expression of a cDEG, Myosin1B (MYO1B), and qRT-PCR and Western Blot analysis showed that MYO1B expression was significantly upregulated between the control group and the P.m cocultured group (P<0.001), and its expression followed a time-dependent and concentration-dependent manner. Conclusion P.m played an important role in the transcriptome of oral keratinocytes.

Objective:To summarize the effect of reverse homodigital dorsal thumb flap in repairing thumb pulp defect.Methods:A retrospective case series study was conducted to analyze the clinical data of patients with thumb pulp defects admitted to the People's Hospital of Renqiu from March 2010 to June 2020. The dorsal homodigital island flap of the proximal phalanx was designed and harvested. During the procedure, the proximal digital artery of the perforator vessels of the flap was cut off and ligated. The digital artery pedicled flap was retrograde transferred to cover the thumb pulp defect. 9-0 line was used to anastomose the dorsal digital nerve with the proper digital nerve. The donor site was repaired with a free skin graft.Results:A total of 68 cases of thumb pulp defects were enrolled, all of whom were accompanied by exposure of the tendon of the distal phalanx. There were 39 males and 29 females, aged from 18 to 63 years (average of 35.8 years). The size of the proximal dorsal island flap was 2.0 cm × 3.0 cm to 3.1 cm × 4.2 cm. All flaps and skin grafts survived, and wounds healed primarily. All patients were followed up for 6 to 28 months (mean, 10.6 months). The color, texture, and contour of the flaps were good. All repaired thumbs got the normal function of extension and flexion. At the last follow-up, the two-point discrimination of flaps was 4-11 mm.Conclusions:It has the advantages of small trauma, simple operation, and good curative effect, using the homodigital dorsal thumb flap to repair the thumb pulp defect.

Objective:To investigate the therapeutic effect of reverse proximal segment dorsal flap of radial digital artery of the thumb in repairing thumb tip defects.Methods:A retrospective case series study was conducted to analyze the clinical data of 56 patients with thumb tip defects admitted to Renqiu People 's Hospital from February 2010 to October 2020. There were 37 males and 19 females，aged 17-66 years［（37.8±12.2）years］. The injury on the right side was observed in 35 patients and on the left side in 21 patients. All of them were thumb tip defects with exposed distal phalanx. Dimension of skin defects was 2.9 cm×1.8 cm-3.3 cm×2.6 cm.The reverse proximal segment dorsal flap of thumb radial digital artery was used，with the dorsal digital nerve sutured with the proper digital nerve. The donor site was repaired with free skin graft from the ulnar side of the affected forearm. The time of flap harvesting，operation time and healing of the flap were measured. At the last follow-up，the shape，texture，sensory recovery and complications of the flap were observed. One month after operation and at the latest follow-up，the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association and Vancouver Scar Scale（VSS）score were used to evaluate the recovery of sensory function of the flap and scar formation of the donor sites，respectively. Results:All patients were followed up for 6-26 months［（13.2±6.4）months］. The time of flap harvesting ranged from 20 to 35 minutes［（26.0±5.3）minutes］. The operation time was 1-2 hours［（1.3±0.3）hours］. Blisters appeared at the distal end of the flap in 2 patients after operation，but they were not treated. After 7 days，the blisters subsided and the flaps survived. The other flaps survived successfully. The donor sites healed by first intention. At the last follow-up，the flaps showed relatively cosmetic appearance，similarities in texture，elasticity and color to the surrounding area and good sensory recovery，without scar contracture and dystrophy of interphalangeal joint. According to the upper limb function evaluation standard set up by hand surgery branch of Chinese Medical Association，56 patients exceeded S3 grade compared to none at postoperative 1 month（ P<0.01），and the VSS score was 3-7 points［（5.0±1.4）points］compared to 6-12 points［（8.8±1.5）points］at postoperative 1 month（ P<0.01）. The donor site left a linear scar，which had no significant effect on its shape and function. Conclusion:The reverse proximal segment dorsal flap of the radial digital artery of the thumb can be used to repair thumb tip defects，for it has advantages of easy operation，a high survival rate as well as good appearance and sensory function recovery，with less damage to the donor area.
