OBJECTIVES: To evaluate the report quality, methodological quality and evidence quality of the systematic reviews and meta-analyses (SRs/MAs) of acupuncture for in vitro fertilization-embryo transfer (IVF-ET). METHODS: The SRs/MAs of acupuncture for IVF-ET were searched electronically from databases of CNKI, Wanfang, VIP, SinoMed, PubMed, Embase, Cochrane Library, from inception of each database to September 27th, 2022. Two reviewers independently screened the literature and extracted the data. Using PRISMA statement, the AMSTAR 2 scale and the GRADE system, the report quality, methodological quality and evidence quality of the included SRs/MAs were assessed. RESULTS: A total of 28 SRs/MAs were included, with PRISMA scores ranging from 8.5 points to 27 points. The problems of report quality focused on protocol and registration, retrieval, risk of bias in studies, additional analysis, limitations and funding. The methodological quality of included studies was generally low, reflecting on items 2, 3, 7, 10, 12 and 16. A total of 85 outcome indexes were included in the GRADE system for evidence grade evaluation. Most of the evidences were low or very low in quality. The reasons for the downgrade were related to study limitations, inconsistency, imprecision and publication bias. CONCLUSIONS: Acupuncture therapy improves the outcomes of IVF-ET, but the methodological quality and evidence quality of related SRs/MAs are low. It is recommended to conduct more high-quality studies in the future to provide more reliable evidences.

Use of Evidence-Based Research Approach in RCTs of Acupuncture-Related Therapies for Primary Dysmenorrhea: A Meta-Research.

OBJECTIVE: To assess the use of evidence-based research (EBR) approach in randomized controlled trials (RCTs) of acupuncture-related therapies for primary dysmenorrhea (PD). METHODS: PubMed, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wanfang Database, Chinese Biomedical Database, and China Science and Technology Journal Database were searched from January 2013 to December 2022 for RCTs of acupuncture on PD. The full text and references of each RCT were read to assess whether systematic reviews (SRs) or other types of studies with similar research questions and end-users' perspectives were cited to justify and design the trial. In addition, the discussion section were analyzed to evaluate whether trials placed the new result in the existing SRs to draw a conclusion. Multivariable logistic regression was used to find variables that associated with 3 aspects of EBR approach: (1) citing clinical studies for justification, (2) citing relevant studies that obtain the perspectives of end users, and (3) citing clinical studies for results discussion. RESULTS: Of 473 RCTs included, 45.67% (216) of the trials cited relevant similar studies, 21.56% (102) referenced to the studies that collected end-users' perspectives, and 10.99% (52) placed result in the context of the previous research. Few RCTs appropriately applied EBR approach. Among all the included studies, 3.17% (15) of the trials used SRs to inform study questions but none of them used updated SRs with acceptable quality; 1.05% (5) of the trials cited SRs of end-user's perspectives in the justification and design of the study, and only 1 trial added results in existing SR to draw a conclusion. Year of publication, language, funding, registration, ethical approval and number of sites were significantly associated with 1 of the 3 aspects of EBR approach. CONCLUSIONS: Few RCTs in acupuncture-related therapies for PD used the EBR approach to minimize research redundancy. Researchers, research institutes, funding agencies, ethics committees, journals and peer reviewers in acupuncture should make efforts to use and promote the EBR approach to ensure the value of new trials.

Methylation of ESR1 promoter induced by SNAI2-DNMT3B complex promotes epithelial-mesenchymal transition and correlates with poor prognosis in ERα-positive breast cancers.

Estrogen receptor α (ERα) serves as an essential therapeutic predictor for breast cancer (BC) patients and is regulated by epigenetic modification. Abnormal methylation of cytosine phosphoric acid guanine islands in the estrogen receptor 1 (ESR1) gene promoter could silence or decrease ERα expression. In ERα-negative BC, we previously found snail family transcriptional repressor 2 (SNAI2), a zinc-finger transcriptional factor, recruited lysine-specific demethylase 1 to the promoter to transcriptionally suppress ERα expression by demethylating histone H3 lysine 4 dimethylation (H3K4me2). However, the role of SNAI2 in ERα-positive BC remains elusive. In this study, we observed a positive correlation between SNAI2 and ESR1 methylation, and SNAI2 promoted ESR1 methylation by recruiting DNA methyltransferase 3 beta (DNMT3B) rather than DNA methyltransferase 1 (DNMT1) in ERα-positive BC cells. Subsequent enrichment analysis illustrated that ESR1 methylation is strongly correlated with cell adhesion and junction. Knocking down DNMT3B could partially reverse SNAI2 overexpression-induced cell proliferation, migration, and invasion. Moreover, high DNMT3B expression predicted poor relapse-free survival and overall survival in ERα-positive BC patients. In conclusion, this study demonstrated the novel mechanisms of the ESR1 methylation mediated with the SNAI2/DNMT3B complex and enhanced awareness of ESR1 methylation's role in promoting epithelial-mesenchymal transition in BC.

[Fidelity in acupuncture-moxibustion clinical research: application and reflection].

As an indicator that measures the degree of implementation of intervention measures during the implementation process, fidelity could be used for monitoring and quality evaluation of the completion degree of intervention measures, and plays an important role in improving the degree of intervention implementation and clarifying the factors that affect intervention implementation. This article aims to introduce the connotation and significance, measurement, control, and current application status of fidelity, as well as the current application status of fidelity in acupuncture-moxibustion clinical research and its inspiration for future research. Meanwhile, based on the existing evaluation tool development methods of fidelity and the characteristics of acupuncture-moxibustion clinical research, a preliminary fidelity evaluation framework is proposed. Introducing fidelity into acupuncture-moxibustion clinical research could improve the implementation quality and compliance of acupuncture-moxibustion in clinical research, increase the credibility and effectiveness of clinical research results, and promote the transformation of acupuncture-moxibustion experience into easily learnable and promotable treatment plans.

Clinical and imaging analysis of 22 cases of supernumerary teeth in the mandibular region.

PURPOSE: This study aimed to describe clinical and imaging analysis of supernumerary teeth in the mandibular region of 22 cases. STUDY DESIGN: Retrospective study METHODS: : This study enrolled patients diagnosed with supernumerary teeth who underwent cone beam computed tomography (CBCT) at Stomatology Hospital of Xi'an Jiaotong University from August 2016 to September 2022. Participants included individuals aged 7-29 years of both genders. The following variables were examined: number of supernumerary teeth, location, shape, direction, length, relationship with adjacent teeth and surrounding anatomical structures, and secondary effects RESULTS: : Out of 236 subjects, 22 (6.02%) were found to have supernumerary teeth in the mandibular region, with a total of 62 teeth identified. The male-to-female ratio was 5:6. Most supernumerary teeth were located in the lingual side of the mandibular region, particularly in the 34-35 tooth area (21.66%), followed by the 44-45 tooth region. The vast majority of supernumerary teeth (96.77%) were impacted, and more than half (51.67%) were located near the mental nerve canal. The average length of the supernumerary teeth was 10.5 mm. While no primary complications were observed, some secondary symptoms were noted, such as the ectopic eruption of adjacent teeth and crowding of permanent teeth. CONCLUSION: The supernumerary teeth in the mandibular area have regional characteristics, which can provide for clinical diagnosis and treatment. CBCT can accurately analyze the location of supernumerary teeth and their secondary effects, and provides the treatment plan on that basis.

Approach to Assess Adequacy of Acupuncture in Randomized Controlled Trials: A Systematic Review.

OBJECTIVE: To summarize and identify the available instruments/methods assessing the adequacy of acupuncture in randomized controlled trials (RCTs) for proposing a new improved instrument. METHODS: A systematic literature search was carried out in 7 electronic databases from inception until 21st November 2022. Any study evaluating the adequacy or quality of acupuncture, specifying specific acupuncture treatment-related factors as criteria of subgroup analysis, or developing an instrument/tool to assess the adequacy or quality of acupuncture in an RCT was included. Basic information, characteristics and contents of acupuncture adequacy assessment were presented as frequencies and percentages. RESULTS: Forty studies were included in this systematic review. Thirty-five studies (87.50%) were systematic reviews, none of which used formal methods to develop the assessment instruments/methods of acupuncture adequacy; of 5 methodological studies, only 1 study used a relatively formal method. Thirty-two studies (82.05%) assessed the components of acupuncture, while 7 (17.95%) assessed the overall quality of acupuncture. An independent assessment instrument/method was used to assess acupuncture adequacy in 29 studies (74.35%), whereas as one part of a methodological quality assessment scale in 10 (25.65%). Only 9 (23.00%) studies used the assessment results for subgroup analysis, sensitivity analysis or the criteria for inclusion in the meta-analysis. CONCLUSION: Assessment contents for adequacy or quality of acupuncture in RCTs hadn't still reached consensus and no widely used assessment tools appeared. The methodology of available assessment instruments/scales is far from formal and rigorous. A new instrument/tool assessing adequacy of acupuncture should be developed using a formal method.

[Analysis on influencing factors of acupuncture curative effect based on experts' experience].

To explore the influencing factors of acupuncture curative effect in literature of experts' experience. The journal literature of experts' experience was retrieved from China National Knowledge Infrastructure (CNKI) and PubMed, starting from inception to September 4, 2020, and the influencing factors of acupuncture curative effect were extracted and analyzed. A total of 499 articles were included, involving 495 articles in Chinese and 4 articles in English. The influencing factors of acupuncture curative effect mainly include five aspects: diagnostic method, acupoint selection of acupuncture, acupuncture manipulation, regulating mind of acupuncture and acupuncture time, and provide reference for acupuncture protocol design in clinical trials.

Transcranial Electrical Stimulation for Relief of Peripartum Mental Health Disorders in Women Undergoing Cesarean Section With Combined Spinal-Epidural Anesthesia: A Pilot Randomized Clinical Trial.

Objective: This study aimed to explore transcranial electrical stimulation (tES) to relieve peripartum anxiety and depressive symptoms in women undergoing cesarean section with combined spinal-epidural anesthesia. Methods: This double-blind, randomized, sham-controlled trial was conducted in the Affiliated Hospital of Xuzhou Medical University from March 2021 and May 2021. One hundred and forty-eight full-term parturients giving birth by elective cesarean section were selected, and 126 were included in the intent-to-treat analysis. Parturients were provided standardized anesthesia and randomized to the active-tES (a-tES) group and sham-tES group. Parturients and outcome assessors were blinded to treatment allocation. The primary outcome was the changes in peripartum mental health disorders, including anxiety, assessed by the Pregnancy-Related Anxiety Questionnaire-Revised 2 (PRAQ-R2). Secondary outcomes included peripartum depressive symptoms, assessed by the Edinburgh Postnatal Depression Scale (EPDS), maternal satisfaction, fatigue level, sleep quality index, and pain score during and after operation. Data were collected before entering the operating room (T0), between post-anesthesia and pre-surgery (T1), before leaving the operating room (T2), and at 24 h post-surgery (T3). Results: One hundred and twenty-six eligible parturients were enrolled in the two groups: a-tES group (N = 62) and sham-tES group (N = 64). Treatment with tES resulted in significantly lower scores of anxiety compared with sham-tES (T2: P < 0.001; T3: P = 0.001). Moreover, the a-tES groups showed a significant reduction in depression scores (T2: P = 0.003; T3: P = 0.032). Conclusion: In this randomized pilot study, tES treatment is efficacious in alleviating peripartum anxiety and depressive symptoms in women undergoing cesarean section and has been demonstrated to be a novel strategy for improving peripartum mental health disorders.

Effects of individualized positive end-expiratory pressure combined with recruitment maneuver on intraoperative ventilation during abdominal surgery: a systematic review and network meta-analysis of randomized controlled trials.

Low tidal volume ventilation strategy may lead to atelectasis without proper positive end-expiratory pressure (PEEP) and recruitment maneuver (RM) settings. RM followed by individualized PEEP was a new method to optimize the intraoperative pulmonary function. We conducted a systematic review and network meta-analysis of randomized clinical trials to compare the effects of individualized PEEP + RM on intraoperative pulmonary function and hemodynamic with other PEEP and RM settings. The primary outcomes were intraoperative oxygenation index and dynamic compliance, while the secondary outcomes were intraoperative heart rate and mean arterial pressure. In total, we identified 15 clinical trials containing 36 randomized groups with 3634 participants. Ventilation strategies were divided into eight groups by four PEEP (L: low, M: moderate, H: high, and I: individualized) and two RM (yes or no) settings. The main results showed that IPEEP + RM group was superior to all other groups regarding to both oxygenation index and dynamic compliance. LPEEP group was inferior to LPEEP + RM, MPEEP, MPEEP + RM, and IPEEP + RM in terms of oxygenation index and LPEEP + RM, MPEEP, MPEEP + RM, HPEEP + RM, IPEEP, and IPEEP + RM in terms of dynamic compliance. All comparisons were similar for secondary outcomes. Our analysis suggested that individualized PEEP and RM may be the optimal low tidal volume ventilation strategy at present, while low PEEP without RM is not suggested.

Automated machine learning-based model predicts postoperative delirium using readily extractable perioperative collected electronic data.

OBJECTIVE: Postoperative delirium (POD) is a common postoperative complication that is relevant to poor outcomes. Therefore, it is critical to find effective methods to identify patients with high risk of POD rapidly. Creating a fully automated score based on an automated machine-learning algorithm may be a method to predict the incidence of POD quickly. MATERIALS AND METHODS: This is the secondary analysis of an observational study, including 531 surgical patients who underwent general anesthesia. The least absolute shrinkage and selection operator (LASSO) was used to screen essential features associated with POD. Finally, eight features (age, intraoperative blood loss, anesthesia duration, extubation time, intensive care unit [ICU] admission, mini-mental state examination score [MMSE], Charlson comorbidity index [CCI], postoperative neutrophil-to-lymphocyte ratio [NLR]) were used to established models. Four models, logistic regression, random forest, extreme gradient boosted trees, and support vector machines, were built in a training set (70% of participants) and evaluated in the remaining testing sample (30% of participants). Multivariate logistic regression analysis was used to explore independent risk factors for POD further. RESULTS: Model 1 (logistic regression model) was found to outperform other classifier models in testing data (area under the curve [AUC] of 80.44%, 95% confidence interval [CI] 72.24%-88.64%) and achieve the lowest Brier Score as well. These variables including age (OR = 1.054, 95%CI: 1.017~1.093), extubation time (OR = 1.027, 95%CI: 1.012~1.044), ICU admission (OR = 2.238, 95%CI: 1.313~3.793), MMSE (OR = 0.929, 95%CI: 0.876~0.984), CCI (OR = 1.197, 95%CI: 1.038~1.384), and postoperative NLR (OR = 1.029, 95%CI: 1.002~1.057) were independent risk factors for POD in this study. CONCLUSIONS: We have built and validated a high-performing algorithm to demonstrate the extent to which patient risk changes of POD during the perioperative period, thus leading to a rational therapeutic choice.

Urinary albumin creatinine ratio associated with postoperative delirium in elderly patients undergoing elective non-cardiac surgery: A prospective observational study.

INTRODUCTION: The blood-brain barrier (BBB) disruption contributes to postoperative delirium, but cost-effective and non-invasive assessment of its permeability is not practicable in the clinical settings. Urine albumin to creatinine ratio (UACR), reflecting systemic vascular endothelial dysfunction, may be a prognostic and predictive factor associated with postoperative delirium. The aim was to analyze the relationship between UACR and postoperative delirium in elderly patients undergoing elective non-cardiac surgery. MATERIALS AND METHODS: Through stratified random sampling, a cohort of 408 individuals aged 60 years and older scheduled for elective non-cardiac surgery were included between February and August 2019 in the single-center, prospective, observational study. The presence of delirium was assessed using the Confusion Assessment Method (CAM) or Confusion Assessment Method for the ICU (CAM-ICU) on the day of surgery, at 2 h after the surgery ending time and on the first 3 consecutive days with repeated twice-daily, with at least 6-h intervals between assessments. Urine samples were collected on one day before surgery, and 1st day and 3rd day after surgery. The primary outcome was the presence of postoperative delirium, and association of the level of UACR with postoperative delirium was evaluated with unadjusted/adjusted analyses and multivariable logistic regression. RESULTS: Postoperative delirium was observed in 26.75% (107 of 400) of patients within 3 days post-surgery. UACR-Pre (OR, 1.30; 95% CI, 1.14-1.49, p < 0.001), UACR-POD1 (OR, 1.20; 95% CI, 1.13-1.27, p < 0.001), and UACR-POD3 (OR, 1.14; 95% CI, 1.08-1.20, p < 0.001) between the delirium and non-delirium groups show a significant difference, even after adjusting for age, education levels, and other factors. CONCLUSION: As the marker of endothelial dysfunction, the high perioperative UACR value may be linked to the postoperative delirium in elderly patients undergoing elective non-cardiac surgery.

Prognostic Value of Vimentin Is Associated With Immunosuppression in Metastatic Renal Cell Carcinoma.

Introduction: Vimentin, a classical marker of epithelial-mesenchymal transition, reflects the invasiveness of cancer cells. Its role in the genesis and progression of tumor has been reported in various cancers, including renal cell carcinoma. However, the impact of vimentin on tumor microenvironment, particularly its implication with tumor-infiltrating immune cells, is unknown. Methods: We conducted this study in 231 patients with metastatic renal cell carcinoma (mRCC) to determine the potential relationship between vimentin and immune status. Using immunohistochemical staining, expression of vimentin, CD8, FOXP3, programmed cell death protein 1 (PD-1), and programmed cell death ligand 1 (PD-L1) were evaluated in resected tumor tissue. Kaplan-Meier analysis and Cox regression models were used for survival analysis. Chi-square test, Fisher exact test, and Mann-Whitney U-test were used for comparison between vimentin high and low groups. Results: High expression of vimentin, stroma PD-L1, and PD-1 indicated poor overall survival, whereas low regulatory T cell or high CD8+ T cell infiltration indicated long overall survival. Stroma PD-L1 (P = 0.030), vimentin (P = 0.026) expression, and CD8+ T cell infiltration (P < 0.001) were independent prognostic factors in mRCC. High vimentin expression was accompanied by high PD-1, PD-L1 expression, and increased regulatory T cell infiltration (all P < 0.001), indicating immunosuppression in the tumor microenvironment. Conclusions: We revealed that vimentin expression was associated with immunosuppression in mRCC, and the immune-suppressive status might be possibly posed by PD-1/PD-L1. Patients with high vimentin expression may acquire potential benefit from the recently approved PD-1/PD-L1 inhibitors. However, further clinical trials are needed to validate our findings.

[Application of 3D printing in the treatment of unilateral comminuted zygomatic bone fracture].

To explore the validity of 3D printing technique in the treatment of unilateral comminuted zygomatic bone fracture. METHODS: Twenty-one patients with unilateral comminuted zygomatic bone fracture were included in the present study, which were treated from hospital January 2014 to April 2017. All patients underwent CT scan and the data were imported in Mimics 10.01 software. The zygomatic bone of healthy side was mirrored to the fracture side to rebuild a "perfect" reduction model. Bone fixation plates were pre-modeled on the model printed by a 3D printing machine and used for bone reduction and fixation during operation. Three dimensional measurements were performed to evaluate the validity of 3D printing based on pre- and post-operative three dimensional CT model. SPSS25.0 software package was used to perform paired t test on the measured data. RESULTS: No significant difference were observed between postoperative CT model and preoperative "perfect" reduction model. All patients were satisfied with their facial appearance. CONCLUSIONS: 3D printing technique is helpful to improve the accuracy of reduction of unilateral comminuted zygomatic bone fracture via preoperative pre-modeling.

Current Understanding of Human Enterovirus D68.

Human enterovirus D68 (EV-D68), a member of the species Enterovirus D of the Picornaviridae family, was first isolated in 1962 in the United States. EV-D68 infection was only infrequently reported until an outbreak occurred in 2014 in the US; since then, it has continued to increase worldwide. EV-D68 infection leads to severe respiratory illness and has recently been reported to be linked to the development of the neurogenic disease known as acute flaccid myelitis (AFM), mostly in children, seriously endangering public health. Hitherto, treatment options for EV-D68 infections were limited to supportive care, and as yet there are no approved, specific antiviral drugs or vaccines. Research on EV-D68 has mainly focused on its epidemiology, and its virologic characteristics and pathogenesis still need to be further explored. Here, we provide an overview of current research on EV-D68, including the genotypes and genetic characteristics of recent epidemics, the mechanism of infection and virus-host interactions, and its relationship to acute flaccid myelitis (AFM), in order to broaden our understanding of the biological features of EV-D68 and provide a basis for the development of effective antiviral agents.

The roles of Wnt/ß-catenin signaling pathway related lncRNAs in cancer.

Long noncoding RNAs (lncRNAs), with length of more than 200 nucleotides, are not translated into proteins but involved in multiple diverse diseases, especially tumorigenesis. The dysregulation of lncRNAs greatly contributes to the progression of various tumors through specific signaling pathways, including Wnt/ß-catenin signaling pathway, which is associated with malignant features of tumors. The interactions between lncRNAs, which have specific expression characteristics in diverse cancer tissues, and Wnt/ß-catenin signaling pathway, exhibit potential as novel biomarkers and therapeutic targets. In this review, we aim to present research findings on the roles of Wnt pathway-related lncRNAs and their effects on Wnt/ß-catenin signaling to regulate tumorigenesis in different cancer types. Results may be used as basis to develop or improve strategies for treatment of different carcinomas.

Immunoscore System for Predicting Clinical Outcome of Metastatic Renal Cell Carcinoma Patients Treated with Tyrosine Kinase Inhibitors.

We conducted this study to determine whether immunoscore system (IS) predicts survival in patients with metastatic renal cell carcinoma (mRCC). A total of 218 mRCC patients treated with sunitinib or sorafenib in Zhongshan Hospital, Fudan University were recruited during 2007-2017, retrospectively. CD8, CD4, Treg, PD-1 and PD-L1 expression were evaluated by immunohistochemical staining of paraffin embedded slide. Kaplan-Meier method and COX regression model were used in survival analyses. Multivariate analyses demonstrated that expressions of CD8, Treg, PD-1 and stromal PD-L1 (sPD-L1) expressions were independent predictive factors for OS, thus IS was established containing these four immunological factors. Subsequent analysis revealed that performance of IS provided good differentiation of OS and PFS. Besides, multivariate analysis identified IS as an independent prognostic factor for OS (p<0.001) and PFS (p=0.002). IS, compared with International mRCC Database Consortium (IMDC) risk model, and provided better prediction ability for OS. Results suggested that IS was a powerful prognostic factor for OS and PFS in patients with mRCC treated with tyrosine kinase inhibitors. And IS can be used as essential supplement to IMDC for outcome prediction in mRCC patients.
