ObjectiveTo investigate the effects of Schisandrae Chinensis Fructus lignans on schizophrenia induced by dizocilpine maleate （MK-801） in mice and to clarify its mechanism. MethodsMale mice of 4-6 weeks old were randomized into blank， model， positive drug， and low-， medium-， and high-dose （40， 80， 160 mg·kg^-1， respectively） Schisandrae Chinensis Fructus lignans groups. The blank group was administrated with distilled water， and the other groups were injected with 0.5 mg·kg^-1 MK-801 to induce schizophrenia symptoms. Meanwhile， risperidone was injected at 0.2 mg·kg^-1 in the positive drug group， and mice in the intervention groups were injected with corresponding drugs for 14 consecutive days. The behavioral changes of mice were observed by autonomous activity test， open field test， forced swimming test， and water maze test. The levels of dopamine （DA） and 5-hydroxytryptamine （5-HT） in the brain and tumor necrosis factor-α （TNF-α） and nuclear factor-κB （NF-κB） in peripheral blood were quantified by enzyme-linked immunosorbent assay （ELISA）. The changes in the prefrontal lobe of mice were observed by hematoxylin-eosin staining， and the changes of the hippocampal tissue were observed by Nissl staining. The protein levels of silencing information regulatory factor 1 （SIRT1） and forkhead box protein O3a （FoxO3a） in the hippocampus of mice were determined by Western blot. ResultsCompared with the model group， low， medium， and high doses of Schisandrae Chinensis Fructus lignans reduced the total number of autonomous activities， total distance in the open field test， immobile time in the forced swimming test， and levels of TNF-α and NF-κB in peripheral blood （P<0.05）， while increasing the number of platform crossings in the water maze test and DA and 5-HT levels in the brain tissue （P<0.05）. Compared with the model group， risperidone and low， medium， and high doses of Schisandrae Chinensis Fructus lignans improve the neural cell morphology in the CA1 region， with full cells in neatly dense arrangement and exhibiting clear membrane boundary. Schisandrae Chinensis Fructus lignans inhibited the expression of SIRT 1 and FoxO3a in the hippocampus （P<0.05）. ConclusionTo sum up， Schisandrae Chinensis Fructus lignans may improve the behavior of schizophrenic mice by activating the SIRT1/FoxO3a signaling pathway to exert neuroprotective effects.

Nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) is a cytosolic pattern recognition receptor that recognizes multiple pathogen-associated molecular patterns and damage-associated molecular patterns. It is a cytoplasmic immune factor that responds to cellular stress signals, and it is usually activated after infection or inflammation, forming an NLRP3 inflammasome to protect the body. Aberrant NLRP3 inflammasome activation is reportedly associated with some inflammatory diseases and metabolic diseases. Recently, there have been mounting indications that NLRP3 inflammasomes play an important role in liver injuries caused by a variety of diseases, specifically hepatic ischemia/reperfusion injury, hepatitis, and liver failure. Herein, we summarize new research pertaining to NLRP3 inflammasomes in hepatic injury, hepatitis, and liver failure. The review addresses the potential mechanisms of action of the NLRP3 inflammasome, and its regulation in these liver diseases.

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 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 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.

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.
