The oral cavity harbors a diverse population of microorganisms,making it one of the most heavily colo-nized sites in the human body.Maintaining a balanced microecology is crucial for oral health.Ligilactobacillus salivarius as a species of Ligilactobacillus,has good oral colonization ability and potential to improve oral microecology for disease prevention and control.Currently,the application and mechanism of Ligilactobacillus salivarius in oral diseases include several aspects.First,by directly inhibiting the growth of Streptococcus mutans and downregulating the expression of its cariogenic virulence factor,gtfs,the aim is to reduce the number of adherent Streptococcus mutans on the tooth surface,thereby preventing dental caries.Second,reducing the number of keystone taxa in periodontitis,and the virulence fac-tors of Aggregatibacter actinomycetemcomitans,including CdtB and LtxA,can alleviate local stimulation in patients with periodontitis.Additionally,directly inhibiting macrophage MAPK and NF-κB pathway activation suppresses osteoclasto-genesis and reduces periodontal bone absorption.In mucosal inflammation,Ligilactobacillus salivarius competes with Candida albicans,inhibits the formation of pathogenic hyphae or germ tubes,and prevents monilial stomatitis.Ligilacto-bacillus salivarius can also reduce the amount of Staphylococcus aureus and mitigate the activation of the macrophage TLR/PI3K/Akt/mTOR and TLR/PI3K/Akt/IκB/NF-κB pathways induced by S.aureus infections,thus alleviating inflam-mation in the oral and pharyngeal regions.In vitro studies on oral tumors have revealed that Ligilactobacillus salivarius can downregulate the expression of cancer cell Akt/Cyclin D1,induce direct apoptosis of tumor cells,reduce COX-2 ex-pression,and improve the tumor immune-suppressive microenvironment.Previous studies have revealed considerable variability in Ligilactobacillus salivarius,necessitating more detailed research to clarify its clinical effects,safety,and mechanisms.Despite the emergence of novel microbiological research techniques,their application to Ligilactobacillus salivarius remains relatively limited.One crucial direction for future research is to better utilize these methods to investi-gate the effects of Ligilactobacillus salivarius on oral diseases.Considering these factors,this study provides a compre-hensive review of existing research studies on Ligilactobacillus salivarius in the fields of oral medicine and dentistry,with the aim to serve as a reference and guide for future studies.

Objective:This study aimed to evaluate the diagnostic value of serum Golgi protein 73(GP73) alone and GP73 combined with liver stiffness measurement (LSM), aspartate aminotransferase/platelet ratio index (APRI), and 4-factor-based fibrosis index (FIB4) in diagnosing liver fibrosis in patients with chronic liver disease of different etiologies.Methods:A diagnostic test. A total of 68 patients who underwent liver biopsy in the Department of Traditional and Western Medical Hepatology of the Third Hospital of Hebei Medical University from October 2019 to December 2020 were selected to detect serum GP73 levels. iLivTouch was used to assess liver stiffness measurement (LSM). In addition, serum alanine aminotransferase (ALT), aspartate aminotransferase (AST), gamma-glutamyl transferase (GGT), total bilirubin (TBil), direct bilirubin (DBil), triglyceride (TG), total cholesterol (TC), low-density lipoprotein (LDL) levels, and peripheral platelet (PLT) counts were assayed. The correlation between GP73 and the above indexes was assessed, and APRI and FIB-4 were calculated. SPSS 21.0 statistical software was used for statistical analysis. The area under the receiver operating characteristic curve was calculated to evaluate diagnostic efficacy of GP73 in identifying hepatic fibrosis stages. Furthermore, the difference between GP73 and liver stiffness, as well as APRI and FIB4 in diagnosing significant fibrosis was assessed.Results:Based on liver biopsy, 13, 18, 17, and 20 cases were diagnosed as stages S0-1, S2, S3, and S4, respectively. The AUC of GP73 diagnosing hepatic fibrosis stage S≥3 and S=4 were 0.806 and 0.844 at cut-off points of 2.06 and 3.27 μg/L, and the sensitivity and specificity were 93.5%, 61.5%, 90.0%, 70.3%, respectively. In addition, GP73 levels were positively correlated with the degree of liver fibrosis ( r=0.547, P<0.001). Conclusions:The efficacy of serum GP73 level in diagnosing the degree of liver fibrosis in patients with chronic liver disease from different causes was significantly higher than that of APRI, FIB4, and LSM. The combination of GP73 and FIB4 can further improve the accuracy of diagnosis of liver fibrosis staging S≥3 and S=4, which is a reliable serological marker for the diagnosis of fibrosis in patients with chronic liver disease.

OBJECTIVE: To explore the genetic characteristics of idic(X)(p11.22) in Turner syndrome (TS). METHODS: Two fetuses suspected for sex chromosome abnormalities or ultrasound abnormalities were selected from Chengdu Women's and Children's Central Hospital in October 2020 and June 2020, and amniotic fluid samples were collected for G-banded chromosomal karyotyping analysis, chromosomal microarray analysis (CMA), and fluorescence in situ hybridization (FISH). RESULTS: The two fetuses were respectively found to have a karyotype of 45,X[47]/46,X,psu idic(X)(p11.2)[53] and 46,X,psu idic(X)(p11.2). CMA found that both had deletions in the Xp22.33p11.22 region and duplications in the p11.22q28 region. FISH showed that the centromeres in both fetuses had located on an isochromosome. CONCLUSION The combination of karyotyping analysis, FISH, and CMA is useful for the delineation of complex structural chromosomal aberrations. High-resolution CMA can accurately identify chromosomal breakpoints, which can provide a clue for elucidating the mechanism of chromosomal breakage and rearrangement.

Objective:To investigate the efficacy and diagnostic accuracy of changes in cytokine levels before and after non-biological artificial liver (referred to as ABL) treatment in patients with acute-on-chronic liver failure (ACLF) in order to establish a basis for treatment timing selection and short-term (28d) prognosis.Methods:90 cases diagnosed with ACLF were selected and divided into a group receiving artificial liver treatment (45 cases) and a group not receiving artificial liver treatment (45 cases). Age, gender, first routine blood test after admission, liver and kidney function, and procalcitonin (PCT) of the two groups were collected. The 28-day survival of the two groups was followed-up for survival analysis. The 45 cases who received artificial liver therapy were further divided into an improvement group and a deterioration group according to the clinical manifestations before discharge and the last laboratory examination results as the efficacy evaluation indicators. Routine blood test, coagulation function, liver and kidney function, PCT, alpha fetoprotein (AFP), β-defensin-1 (HBD-1), 12 cytokines and other indicators were analyzed and compared. A receiver operating characteristic curve (ROC curve) was used to analyze the diagnostic efficacy of the short-term (28 d) prognosis and an independent risk factors affecting the prognosis of ACLF patients. According to different data, Kaplan-Meier method, log-rant test, t-test, Mann-Whitney U test, Wilcoxon rank-sum test, χ2 test, Spearman rank correlation analysis and logistic regression analysis were used for statistical analysis. Results:The 28-day survival rate was significantly higher in ACLF patients who received artificial liver therapy than that of those who did not receive artificial liver therapy (82.2% vs. 61.0%, P<0.05). The levels of serum HBD-1, alpha interferon (IFN-α) and interleukin-5 (IL-5) after artificial liver treatment were significantly lower in ACLF patients than those before treatment ( P<0.05), while liver and coagulation function were significantly improved compared with those before treatment ( P<0.05), and there was no statistically significant difference in other serological indexes before and after treatment ( P＞0.05). Before artificial liver treatment, serum HBD-1 and INF-α levels were significantly lower in the ACLF improvement group than in the deterioration group ( P<0.05) and were positively correlated with the patients' prognosis (deteriorating) ( r=0.591, 0.427, P<0.001, 0.008). The level of AFP was significantly higher in the improved ACLF group than that in the deterioration group ( P<0.05), and was negatively correlated with the prognosis (deteriorating) of the patients ( r=-0.557, P<0.001). Univariate logistic regression analysis showed that HBD-1, IFN-α and AFP were independent risk factors for the prognosis of ACLF patients ( P=0.001, 0.043, and 0.036, respectively), and that higher HBD-1 and IFN-α levels were associated with lower AFP level and a deteriorating prognosis. The area under the curve (AUC) of HBD-1, IFN-α, and AFP for short-term (28d) prognostic and diagnostic efficacy of ACLF patients was 0.883, 0.763, and 0.843, respectively, and the sensitivity and specificty was 0.75, 0.75, and 0.72, and 0.84, 0.80, and 0.83, respectively. The combination of HBD-1 and AFP had further improved the diagnostic efficiency of short-term prognosis of ACLF patients (AUC=0.960, sensitivity and specificity: 0.909 and 0.880 respectively). The combination of HBD-1+IFN-α+AFP had the highest diagnostic performance, with an AUC of 0.989, sensitivity of 0.900, and specificity of 0.947. Conclusion:Artificial liver therapy can effectively improve the clinical symptoms and liver and coagulation function of patients with ACLF; remove cytokines such as HBD-1, IFN-α, and IL-5 in patients with liver failure; delay or reverse the progression of the disease; and improve the survival rate of patients. HBD-1, IFN-α, and AFP are independent risk factors affecting the prognosis of ACLF patients, which can be used as biological indicators for evaluating the short-term prognosis of ACLF patients. The higher the level of HBD-1 and/or IFN-α, the higher the risk of disease deterioration. Therefore, artificial liver therapy should be started as soon as possible after the exclusion of infection. In diagnosing the prognosis of ACLF, HBD-1 has higher sensitivity and specificity than IFN-α and AFP, and its diagnostic efficiency is greatest when combined with IFN-α and AFP.

Objective:This study aims to investigate the prevalence and distribution characteristics of mental disorders among people aged 18 and above in Shandong Province.Methods:In 2015, an epidemiological survey was carried out to investigate the patterns of mental disorders in 49 counties of Shandong Province. A total of 28 000 individuals aged 18 years or older were selected using the multistage stratified cluster sampling method. All these participants were classified as at a high or low risk of mental disorders according to the assessment results of the revised version of the General Health Questionnaire (GHQ). The diagnosis of mental disorders was confirmed using the Structured Clinical Interview for Diagnostic and Statistical Manual, Forth edition (DSM-Ⅳ) axis I or MMSE. All participants at high risk of mental disorders were evaluated using DSM-Ⅳ or MMSE to confirm the psychiatric diagnoses, while 10% of participants at low risk of mental disorders were randomly selected to be evaluated. The prevalence and its 95% confidence interval of mental disorders were adjusted according to study design and sociodemographic characteristics of the sample. The between-group differences of prevalence were compared using chi-square tests or Fisher′s exact tests as appropriately.Results:A total of 27 489 individuals completed survey. The adjusted prevalence of any mental disorder was 17.46% (95 %CI 17.02%-17.89%). The five most prevalent mental disorder spectrums were substance use disorders (5.29%), mood disorders (4.47%), anxiety disorders (4.46%), intellectual and mental disorders due to physical or substance (1.91%), and psychotic disorders (1.12%). The most common mental disorders were alcohol use disorder (5.27%) and major depressive disorder (2.14%). The prevalence of mental disorders in men was higher than that in women (23.37% vs. 13.89%; χ 2=408.91, P<0.01). There was no significant difference in the prevalence of mental disorders between rural residents and urban residents (17.69% vs. 17.20%; χ2=1.05, P=0.305). Of participants with mental disorders, 26.12% (1 047/4 008) had moderate to severe functional impairment and 10.98% (428/3 898) have sought professional help. Conclusion:The prevalence of mental disorders among people aged 18 and above in Shandong Province is basically consistent with the results of similar domestic studies. The prevalence of mental disorder was higher in men than in women and was not differ in participants living in urban and rural areas. Alcohol use disorder, major depressive disorder, non-specific anxiety disorder and non-specific depressive disorder are most common mental disorders.

Nonalcoholic steatohepatitis (NASH) has become the second leading cause of hepatitis and can further progress to liver fibrosis, liver cirrhosis, and even liver cancer; however, the detailed pathogenesis of NASH remains unclear, and there is still a lack of effective therapeutic drugs. MicroRNAs (miRNAs) are a class of non-coding, post-transcriptionally regulated, and highly conserved small RNAs in the body and play an important role in a variety of liver diseases. This article mainly reviews the role of miRNAs in the development and progression of NASH.

Objective:To compare the economic characteristics of the four artificial liver models [plasma exchange, half-dose plasma exchange combined with double plasma adsorption (DPMAS), pre-equal amount of plasma exchange followed by DPMAS, and pre-DPMAS followed by equal amount of plasma exchange] in the treatment of liver failure.Methods:A decision tree model was established with the Treeage pro 2011 software. The cost-effectiveness ratio and incremental cost-effectiveness value of four different treatment modalities were calculated and compared in patients with liver failure at early, mid and late stages, respectively. The sensitivity analysis of the model was performed using data from the preliminary research results of these groups.Results:The cost-effectiveness ratio and incremental cost-effectiveness value of patients treated with artificial liver therapy with half-dose plasma exchange combined with DPAMS plan in early stage liver failure were 89 547.79 and 34 665.34, which was lower than per capita GDP, so the increased cost had cost-effective advantages. In the middle and late stage of liver failure, the cost-effectiveness ratio and incremental cost-effectiveness value of pre-DPMAS followed by equal plasma exchange plan was 122 865.5 and 284 334.97, and 70 744.55 and 75 299.48, respectively, which was less than three times of per capita GDP. The increased cost was acceptable and had economic advantages. The sensitivity analysis results showed that the basic analysis results were reliable.Conclusion:Half-dose plasma exchange combined with DPAMS plan is the most cost-effective treatment for early liver failure, while pre-DPMAS followed by equal plasma exchange plan is the most economical treatment for mid and late stage liver failure.
