BACKGROUND: Acupuncture therapy provides a complementary and alternative approach to treating major depressive disorder (MDD), but its efficacy and safety have still not been comprehensively assessed. Recently published systematic reviews remain confusing and inconclusive. OBJECTIVE: This systematic review evaluated the efficacy and safety of acupuncture therapy alone or combined with antidepressants for adult patients with mild and moderate MDD. SEARCH STRATEGY: Chinese Biomedical Literature Database, China National Knowledge Infrastructure Database, Wanfang Database, Chinese Science and Technology Journal Database, PubMed, Embase, and Cochrane Library were searched from their inceptions to March 2025. INCLUSION CRITERIA: Randomized controlled trials that compared acupuncture therapy with antidepressants, or acupuncture therapy plus antidepressants with acupuncture therapy or antidepressants for adult patients with mild and moderate MDD were included. DATA EXTRACTION AND ANALYSIS: Five reviewers independently extracted data from original literature using a standardized form, and the data were verified by two reviewers to ensure accuracy. Statistical meta-analyses, publication bias analyses, and subgroup analyses were performed by using Review Manager 5.3 software. The Grading of Recommendations Assessment, Development, and Evaluation approach was used to assess the certainty of the evidence. RESULTS: A total of 60 eligible studies including 4675 participants were included. Low-certainty evidence showed that compared with antidepressants, acupuncture therapy (standardized mean difference [SMD] = -0.57; 95% confidence interval [CI] = [-0.87, -0.27]; I² = 86%; P = 0.006) or acupuncture therapy plus antidepressants (SMD = -1.00; 95% CI = [-1.18, -0.81]; I² = 77%; P < 0.00001) may reduce the severity of depression at the end of treatment. Low-certainty evidence indicated that compared with acupuncture therapy alone, acupuncture therapy plus antidepressants slightly reduced the severity of depression at the end of treatment (SMD = -0.38; 95% CI = [-0.61, -0.14]; I² = 18%; P = 0.002). Similar results were also found for acupuncture's relief of insomnia. The reported adverse effects of acupuncture therapy were mild and transient. For most of the subgroup analyses, acupuncture type, scale type, and the course of treatment did not show a significant relative effect. CONCLUSION Acupuncture therapy may provide antidepressant effects and relieve insomnia with mild adverse effects for adult patients with mild and moderate MDD. But the certainty of evidence was very low. More high-quality, well designed, large-scale studies with long-term follow-up are needed in the future.

Objective:To develop and validate clinical predictive models for identifying poor short-term response to recombinant human growth hormone(rhGH) treatment in children with short stature.Methods:A retrospective analysis was conducted on 118 children diagnosed with growth hormone deficiency or idiopathic short stature who were treated at the First Affiliated Hospital of Zhengzhou University and two other hospitals between January 1, 2020, and January 1, 2024. A poor response to rhGH was defined as a height increase of less than 0.2 standard deviation score(SDS) after 6 months of rhGH treatment. LASSO regression was used to identify predictive variables from baseline and follow-up data. Two logistic regression models were conducted: Model A(incorporating baseline variables only) and model B(incorporating both baseline and follow-up variables), and nomograms were created for visualization. External data and internal resampling were used for dual validation of the models, and their performance was compared.Results:A total of 118 children with short stature were included. Six baseline predictive variables(diagnosis, initial height SDS, bone age, bone age-chronological age difference, rhGH dose, and gender) and one follow-up variable(height SDS after 3 months of rhGH treatment) were identified. Area under the curve values for Model A and Model B were 0.753(95% CI 0.696-0.811) and 0.930(95% CI 0.891-0.975), respectively. Calibration curves, decision curve analysis, and other evaluation metrics demonstrated good discrimination and clinical utility for both models. Model B, incorporating the 3-month follow-up variable, showed superior predictive performance compared to Model A. Conclusions:The clinical prediction models developed in this study(Model A and Model B) are practical and reliable tools for quantitatively, conveniently, and intuitively identifying children with short stature at risk of poor response to rhGH treatment.

Real-time analysis of major element content in raw ore slurry represents a crucial part in mining extraction processes.A self-developed real-time online detection system based on laser-induced breakdown spectroscopy(LIBS)was applied for rapid detection of primary elements in raw ore slurry.Using 72 synchronized samples collected from mining enterprises,with 58 samples allocated for model construction and 14 for validation,this research focused on addressing the industrial requirements for real-time monitoring of sulfur(S),arsenic(As),and copper(Cu)elements.Multiple characteristic spectral lines were selected from LIBS detection system's spectral data.The analytical approach combined multiple linear regression(MLR)for initial model development with partial least squares(PLS)full-spectrum analysis for model refinement,ultimately establishing calibration and prediction models for the three target elements.The results demonstrated that the integrated MLR-PLS methodology achieved high precision,with calibration model determination coefficients(R2)of 0.95,0.97,and 0.99,and prediction model R2 values of 0.96,0.94,and 0.99 for S,As and Cu,respectively.The mean relative prediction errors were 1.65%,2.10%and 0.86%,respectively,which could meet the practical production requirements of mining operations.This approach provided an effective technical solution for real-time quality monitoring in mineral slurry processing.

This study was aimed at understanding the etiological and genetic characteristics of Yersinia enterocolica isolated in Jiangsu Province between 2005 and 2019.All 110 identified strains of Y.enterocolica were from patients with foodborne diar-rhea in Jiangsu Province,or from pigs,dogs,cattle,sheep,poultry,flies,or food.Virulence genes,biological serotypes,drug resistance,multilocus sequence typing(MLST),and core genome multilocus sequence typing(cgMLST)based on whole-genome sequencing were performed.The strains included 27 pathogenic strains(24.5％)and 83 non-pathogenic strains(75.5％).Non-pathogenic strains accounted for a high proportion,particularly among strains from patients(15/16,93.8％).The biological serotypes of pathogenic strains were mainly type 3/O∶3(26/27,96.3％).Non-pathogenic strains included 1A/O∶8 type(23/83,27.7％),1 A/O∶5 type(14/83,16.9％),and the other four biological serotypes(excluding unknown se-rotypes).Pathogenic strains were dominated by type 3/O∶3(26/27,96.3％),and more than 80％of these strains were sensi-tive to 19 antibiotic types.Whole-genome sequencing indicated that the pathogenic strains were all ST135 type,whereas the non-pathogenic strains were more diverse and scattered.HierCC clustering analysis grouped all strains into three clus-ters:pathogenic strains were in one cluster,and strains from patients were found in all three clusters.In conclusion,the Y.enterocolica strains from patients were primarily non-patho-genic.Non-pathogenic strains showed richer epigenetic and ge-netic diversity than pathogenic strains.The monitoring of these strains should be strengthened to decrease the risk of human infection.
