Supplementary Material for: Ultrasonographic versus Fluoroscopic Access for Percutaneous Nephrolithotomy: A Meta-Analysis

<b><i>Objective:</i></b> To assess the safety and efficacy of ultrasonographic vs. fluoroscopic access for percutaneous nephrolithotomy (PCNL). <b><i>Methods:</i></b> Medline (PubMed), Embase, Ovid, Cochrane, and the Chinese Biomedical Literature databases were searched to identify clinically controlled trials (CCTs) and randomized controlled trials (RCTs) that compared ultrasonographic access with fluoroscopic access for PCNL. RevMan 5.1 software and Stat Manager V4.1 software were used for the meta-analysis. <b><i>Results:</i></b> Five RCTs and nine CCTs were included in our study, which contained a total of 3,019 patients. Of these, 1,574 (52%) had undergone ultrasonographic access, and 1,445 (48%) had undergone fluoroscopic access. The pooled results revealed that the ultrasonographic access patients had shorter duration of access (min) by 2.56 min (weighted mean difference (WMD) = −2.56, 95% confidence interval (CI): −4.40 to −0.72, p = 0.006). There was a higher stone-free rate in the ultrasonographic access group (odds ratio (OR) = 1.26, 95% CI: 1.02-1.55, p = 0.03), as well as a lower rate of operative complications (OR = 0.72, 95% CI: 0.56-0.93, p = 0.01), reduced intraoperative blood loss (ml) (WMD = −14.55 ml, 95% CI: −27.65 to −1.46, p = 0.03), and a lower rate of blood transfusion requirement (OR = 0.39, 95% CI: 0.24-0.63, p = 0.0001). Sensitivity and subgroup analyses were also performed. <b><i>Conclusion:</i></b> Except for no radiation exposure, our meta-analysis revealed that ultrasonographic access had many advantages, such as a shorter access time, reduced intraoperative blood loss, a lower rate of operative complications, a lower rate of blood transfusion, and a higher stone-free rate. Because of these significant advantages, we recommend the use of ultrasonographic access for PCNL

Supplementary Material for: Comparison between Fondaparinux and Low-Molecular-Weight Heparin in Patients with Acute Coronary Syndrome: A Meta-Analysis

<b><i>Objective:</i></b> A number of studies have evaluated the efficacy and safety of fondaparinux versus low-molecular-weight heparin (LMWH) in patients with acute coronary syndrome (ACS), but the findings were not consistent across these studies.<b><i> Methods:</i></b> Electronic databases and article references were searched for studies that assessed fondaparinux versus LMWH in ACS patients. <b><i>Results:</i></b> Six studies met the inclusion criteria. There was a lower risk of major adverse cardiac events (MACE) with fondaparinux-based regimens both in randomized controlled trials (RCT; risk ratio, RR: 0.91, p = 0.04) and observational studies (RR: 0.85, p < 0.0001). Mortality decreased in fondaparinux-treated patients in RCT (RR: 0.84, p = 0.02), but not in observational studies (RR: 1.44, p = 0.64). For the analysis of myocardial infarction (MI), recurrent ischemia and stroke, none of the studies showed significant results. In addition, fondaparinux lowered the risk of major bleeding in RCT (RR: 0.62, p < 0.0001) and observational studies (RR: 0.65, p < 0.0001). The net clinical outcome also favored fondaparinux over LMWH in RCT (RR: 0.82, p < 0.0001) and observational studies (RR: 0.84, p < 0.0001). <b><i>Conclusions:</i></b> Among ACS patients, a fondaparinux-based regimen presented advantages regarding MACE and major bleeding, and a net clinical benefit compared with LMWH, although the benefit is minimal regarding MACE. For death, MI, recurrent ischemia and stroke, fondaparinux has not shown significant benefits

Supplementary Material for: Tumor-Derived Exosomal Long Noncoding RNAs as Promising Diagnostic Biomarkers for Prostate Cancer

<b><i>Background/Aims:</i></b> Exosomal circulating long non-coding RNAs (lncRNAs) in blood are emerging as clinically useful and non-invasive biomarkers for tumor diagnosis. However, normal cells can also secrete exosomes, so it is a prerequisite to obtain tumor-derived exosomes for better understanding of their diagnostic impacts in cancer. In this study, a dual-antibody-functionalized immunoaffinity system was established to isolate exosomes and investigate their lncRNAs expression pattern and clinical significance in prostate cancer (PCa). <b><i>Methods:</i></b> A commercially available kit was used to isolate total exosomes, which were then purified by a dual-antibody-functionalized immunoaffinity system. RT-qPCR was performed to detect the expression of exosomal lncRNAs. Receiver operating characteristic (ROC) curves were plotted to assess the diagnostic value. <b><i>Results:</i></b> Expression levels of two lncRNAs in tumor-derived exosomes were significantly higher than those in total exosomes. The levels of SAP30L-AS1 were upregulated in benign prostatic hyperplasia (BPH), and SChLAP1 levels were significantly higher in PCa than in BPH and healthy individuals. The area under the ROC curve indicated that SAP30L-AS1 and SChLAP1 had adequate diagnostic value to distinguish PCa from controls. Two lncRNAs separately combined with prostate specific antigen (PSA) possessed a moderate ability for discrimination. SAP30L-AS1 expression level was related to PSA values and tumor invasion. SChLAP1 expression was significantly higher in patients with higher Gleason scores, and was also effective in differentiating between BPH and PCa when the concentration of PSA was in the gray zone. <b><i>Conclusion:</i></b> The isolation of tumor-derived exosomes by dual-antibody-functionalized immunoaffinity systems and detection of their lncRNAs in plasma may lead to the identification of suitable biomarkers, with potential diagnostic utility

Supplementary Material for: The Common Neural Mechanism of Somatic Symptoms of Depression and Anxiety Disorders: A Resting-State Functional Magnetic Resonance Imaging Study

Introduction: Somatic symptoms often occur as a manifestation of depression and anxiety. The subgenual anterior cingulate cortex (sgACC) has been shown to be closely related to both depression and anxiety and plays an important role in somatic symptoms. However, little is known regarding whether the abnormal function of the sgACC contributes to the common somatic symptoms of depression and anxiety. Methods: Resting-state functional connectivity (RSFC) analysis based on the seed of the sgACC was investigated in 23 major depressive disorder (MDD) patients with somatic symptoms, 20 generalized anxiety disorder (GAD) patients with somatic symptoms, and 22 demographically matched healthy controls (HCs). The severity of depression, anxiety, and somatic symptoms was assessed using the Hamilton Depression Rating Scale (HAMD), Hamilton Anxiety Rating Scale (HAMA), and the 15-item somatic symptom severity scale from the Patient Health Questionnaire (PHQ-15), respectively. An analysis of covariance analysis (ANCOVA) was conducted to determine RSFC alterations among GAD, MDD, and HC groups with age, gender, and head motion as covariates. Correlation analyses were conducted between the RSFC of the sgACC and PHQ-15. Results: The significantly different RSFC of right sgACC among the three groups was found in right STG, left cerebellum, and right postcentral. Post hoc analysis indicated that both MDD and GAD patients showed a decreased RSFC between the right sgACC and right STG than HCs, and both were negatively correlated with the PHQ-15 scores. Conclusion: The abnormally decreased RSFC of the sgACC and STG may be the underlying common mechanisms of depression and anxiety combined with somatic symptoms

Supplementary Material for: Chromosome Nomenclature and Cytological Characterization of Sacred Lotus

<p>Sacred lotus is a basal eudicot plant that has been cultivated in Asia for over 7,000 years for its agricultural, ornamental, religious, and medicinal importance. A notable characteristic of lotus is the seed longevity. Extensive endeavors have been devoted to dissect its genome assembly, including the variety China Antique, which germinated from a 1,300-year-old seed. Here, cytogenetic markers representing the 10 largest megascaffolds, which constitute approximately 70% of the lotus genome assembly, were developed. These 10 megascaffolds were then anchored to the corresponding lotus chromosomes by fluorescence in situ hybridization using these cytogenetic markers, and a set of chromosome-specific cytogenetic markers that could unambiguously identify each of the 8 chromosomes was generated. Karyotyping was conducted, and a nomenclature based on chromosomal length was established for the 8 chromosomes of China Antique. Comparative karyotyping revealed relatively conserved chromosomal structures between China Antique and 3 modern cultivars. Interestingly, significant variations in the copy number of 45S rDNA were detected between China Antique and modern cultivars. Our results provide a comprehensive view on the chromosomal structure of sacred lotus and will facilitate further studies and the genome assembly of lotus.</p
