rocardiogram (ECG) containing an R wave (QRS complex). Then ECG was analyzed to diagnose the cardiac rhythms. In conclusion, t-RR is a novel methodology which helps us understand heart rhythms from a new perspective.A nerve stimulation-guided lumbar plexus block is a well-established technique. It is not clear whether ultrasound guidance has additional value for this deep block technique. This study aimed to examine whether ultrasound guidance using a paramedian transverse scan through the intertransverse space (PMTS-ITS) approach in combination with nerve stimulation reduces the onset time of a complete sensory block. Forty-four patients who were scheduled to undergo arthroscopic knee surgery with an ultrasound visibility score (UVS) of ≥10 for the lumbar plexus were enrolled and randomly allocated to the ultrasound guidance with nerve stimulation group (group U-N) or nerve stimulation group (group N) in this prospective, randomized, parallel-group, active-controlled study. The primary outcome was the onset time of a complete sensory block. The results showed that the onset time of a complete sensory block to pinprick and cold was 10 (10-40) min and 10 (10-40) min in group U-N, respectively, and 30 (10-40) min and 20 (10-40) min in group N (P=0.005, P=0.004), respectively. The performance time was 658±87 s in group U-N and 528±97 s in group N (P0.05). Saracatinib in vitro In conclusion, ultrasound guidance using the PMTS-ITS approach in combination with nerve stimulation led to a faster onset of a complete sensory block than nerve stimulation alone for a lumbar plexus block in patients with a UVS ≥10. Ultrasound guidance with nerve stimulation significantly decreased the number of patients who required 5 or more needle passes.Female infertility after occupational exposure to inhaled anesthetic agents has attracted critical attention, but systematic studies focusing on the impact of inhaled anesthetics on the female reproductive system have not been well-established. We used a murine model to study the effect of isoflurane exposure on infertility in female adult mice and investigated the potential underlying mechanism. One hundred adult female C57 mice were randomly allocated into 5 groups exposed in air containing 0, 2500, 5000, 10 000 or 20 000 ppm isoflurane for 15 consecutive days. Estrous cycle length was measured based on vaginal smear examination, ovarian histopathologic enumeration of follicles, and serum estradiol (E2), anti-Mullerian hormone (AMH), follicle-stimulating hormone (FSH), and luteinizing hormone (LH) levels to assess the effect of isoflurane on ovarian reserve. Compared to the control group, significant prolongation of the estrous cycle of the adult female mice was observed in the 20 000 ppm isoflurane exposure group. Serum AMH was significantly decreased, and FSH and LH levels profoundly increased in the 5000, 10 000, and 20 000 ppm isoflurane exposure groups compared to the control group. The histopathologic examination revealed a reduced number of developing follicles and an increased number of atretic follicles after isoflurane exposure, but the difference was not statistically significant. Thus, exposure to a higher concentration of isoflurane might have an adverse effect on ovarian reserve in sexually-mature female mice.Endoscopic cervical foraminotomy is increasingly used for cervical spondylotic radiculopathy (CSR), but there is great concern about radiation exposure because of the heavy dependence of this surgical method on fluoroscopy. The objective of this study was to introduce in detail an advanced surgical technique of keyhole foraminotomy via a percutaneous posterior full-endoscopic approach as a treatment for CSR and investigate its clinical outcomes. We retrospectively reviewed 33 consecutive patients with CSR who underwent keyhole foraminotomy via a percutaneous posterior full-endoscopic approach from October 2015 to April 2017. The patients' general characteristics, including operative time, blood loss, hospital stay, complications, and recurrence, were obtained. Clinical outcomes were evaluated using the visual analogue scale (VAS) for radicular pain, the neck disability index (NDI) for functional assessment, and the modified MacNab criteria for patient satisfaction. All operations were successfully performed (mean operation time, 62 min), with no measurable blood loss or severe related complications. The mean follow-up was 25 months. The VAS and NDI scores were significantly improved as compared with those in the preoperative period (preoperative vs. final follow-up 7.6±1.6 vs. 3.83±7.34 for VAS, P less then 0.01; 69.5%±10.5% vs. 17.54%±13.40% for NDI, P less then 0.01). Of the 33 patients, 32 (97.0%) had good-to-excellent global outcomes and all patients obtained symptomatic improvement. In conclusion, keyhole foraminotomy via a percutaneous posterior full-endoscopic approach is an efficient, safe, and feasible procedure for the treatment of CSR. Its simplified single-step blunt incision for localization appears to decrease radiation exposure risks.Estrogen deficiency, which mainly occurs in postmenopausal women, is a primary reason for osteoporosis in clinical diagnosis. However, the molecular regulation of osteoporosis in menopausal females is still not adequately explained in the literature, with the diagnosis and treatment for osteoporosis being limited. Herein, exosomal microRNAs (miRNAs) were used to evaluate their diagnosis and prediction effects in menopausal females with osteoporosis. In this study, 6 menopausal females without osteoporosis and 12 menopausal females with osteoporosis were enrolled. The serum exosomes were isolated, and the miRNA expression was detected by miRNA high-throughput sequencing. Exosomal miRNA effects were analyzed by Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. The miRNA-targeted genes were evaluated by Targetscan 7.2 and the protein-protein interactions (PPI) by STRING. Hub genes were analyzed by the CytoHubba app of Cytoscape. The results showed that 191 aberrant miRNAs were found in the group of menopausal females with osteoporosis, including 72 upregulated miRNAs and 121 downregulated miRNAs. Aberrant miRNAs were involved in many signaling pathways, such as the Wnt, MAPK, and Hippo pathways. Based on PPI network analysis, FBXL3, FBXL13, COPS2, UBE2D3, DCUN1D1, DCUN1D4, CUL3, FBXO22, ASB6, and COMMD2 were the 10 most notable genes in the PPI network. In conclusion, aberrant serum exosomal miRNAs were associated with an altered risk of osteoporosis in menopausal females and may act as potential biomarkers for the prediction of risk of osteoporosis in menopausal females.
