However, in palatal shelf fusion, miRNA regulation by long non-coding RNAs (lncRNAs) when acting as competing endogenous RNAs (ceRNAs) or miRNA sponges, remains unclear. Methods We systematically analyzed the correlation between lncRNAs, miRNAs, and mRNAs from RNA sequencing profiling in embryonic gestation day 14.5 (E14.5) mouse embryos from control (n=3) and all-trans retinoic acid (ATRA)-treated (n=3) mice. We then constructed a lncRNA-associated ceRNA network. The expression profiles of mRNA, lncRNA, and miRNA were verified by quantitative polymerase chain reaction (qPCR). Results In total, 18 aberrantly expressed miRNAs, 861 mRNAs, and 583 lncRNAs were identified from palate samples of control and ATRA-treated samples. Bioinformatics data and integrative analysis identified 69 lncRNAs, 18 miRNAs, and 78 mRNAs that were aberrantly expressed, and a ceRNA network was then constructed. Finally, we identified a NONMMUT004850.2/NONMMUT024276.2-miR-741-3p/miR-465b-5p-Prkar1α ceRNA network associated with palatal shelf fusion at E14.5. The qPCR results showed that NONMMUT004850.2 (P=5E-05), NONMMUT024276.2 (P=0.0012), and Prkar1α (P=3E-05) were up-regulated, whereas miR-741-3p (P=0.006) and miR-465b-5p (P=1E-04) were down-regulated in ATRA-treated mice compared to the control samples. The qPCR results were in concordance with the RNA sequencing profiling. Conclusions Our study demonstrated that NONMMUT004850.2/NONMMUT024276.2-miR-741-3p/miR-465b-5p-Prkar1α could potentially serve as an important regulatory mechanism of palatal fusion in the development of the cleft palate. 2019 Annals of Translational Medicine.

The development of video-assisted thoracoscopic surgery (VATS) thymectomy by our team offers the advantages of a glasses-free 3D thoracoscopic system for pulmonary surgery. The aim of the present retrospective study was to compare the advantages and short-term outcomes of glasses-free 3D VATS vs. 2D VATS for the treatment of thymic diseases. Methods The medical records of patients who underwent traditional 2D and glasses-free 3D video-assisted thoracoscopic thymectomy at the First Affiliated Hospital of Guangzhou Medical University from May 2015 to December 2018 were retrospectively reviewed, while focusing on the collection, evaluation, and comparison of clinical data and perioperative manifestations. Results A total of 152 patients were included, of which 71 patients underwent glasses-free 3D VATS and 81 underwent 2D VATS. There were no significant differences in demographinnals of Translational Medicine.

Methods Type 2 diabetes patients (n=1,209) were recruited from inner city outpatient diabetes clinics in 2016. Patient demographic, insulin recommendation, diabetes treatment type, intention to receive insulin therapy, and PIR information was collected using self-reports. The patients were divided into three groups those who refused insulin therapy (n=184), those who accepted insulin therapy (n=331), and those not recommended for insulin therapy (n=694). Descriptive statistics were used to calculate the prevalence of insulin refusal; t-tests and analyses of variance were used to compare demographics with PIR. Results The insulin refusal rate was 35.7%. The duration of diabetes, numbers of diabetes-related complications, and glycated hemoglobin levels were significantly lower in the group not recommended for insulin therapy than refused and accepted insulin groups. The level of PIR in insulin refusal group was significantly lower among patients agreeing to receive insulin therapy within 3 months than among those refusing insulin therapy. Conclusions The prevalence of insulin refusal in Korea is not low, and people who refuse insulin therapy have high levels of PIR. Strategies to reduce PIR levels are needed. 2019 Annals of Translational Medicine.

Methods Patients with non-OPSCC diagnosed between 2006 and 2016 were included in this study. The presence of HPV 16 DNA was confirmed by quantitative real-time polymerase chain reaction. Survival analysis was performed using Kaplan-Meier estimates, the Cox proportional hazards model, and propensity score matching (PSM). Results Overall, 1,539 patients with adequate specimens were identified, of whom 131 (8.51%) were positive for HPV 16. Compared to HPV 16-negative patients, the adjusted hazard ratios (aHR) for HPV 16-positive non-OPSCC patients were 0.77 and 0.81 for disease-specific survival (DSS) and overall survival (OS), respectively. Additionally, the larynx was the only subsite in which DSS was significantly improved. After PSM, cohorts consisted of 129 patients in the HPV 16-positive group and 129 in the HPV 16-negative group. HPV 16-positive non-OPSCC patients had favorable survival outcomes, however, these outcomes were not significantly different compared to HPV 16-negative patients. Stratified analysis performed according to primary site showed that only in the larynx was HPV 16-positive status a significant factor for predicting favorable DSS. Conclusions Our findings indicate that HPV 16-positive non-OPSCC patients did not have significantly better survival outcomes compared to HPV 16-negative patients. 2019 Annals of Translational Medicine.

The innate immune system is the first defense line against C. albicans infection. MiR-155, a multifunctional microRNA (miRNA), has been proved to be a crucial regulator in innate immune response against bacterial and virus. However, the biological function of miR-155 in innate immune response against C. albicans infection remains unknown. Methods The expression miR-155, as well as inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ)], in monocytes derived dendritic cells (DCs) during heat-killed C. albicans infection was detected by quantitative reverse-transcriptase polymerase chain reaction (qRT-PCR). The biological functions of miR-155 were investigated with "gain- and loss-of-function" experiments. Potential targets of miR-155 were identified by bioinformatics analysis, luciferase assay and western blot. learn more Small interfering RNA (siRNA) was used to validate the function of miR-155 target. Results C. albicans increased the expression of miR-155 and pro-inflammatory factors. MiR-155 induced by C. albicans was depended on Dectin-1-spleen tyrosine kinase (Syk)/Raf-1-MAPK signaling pathway. Furthermore, miR-155 suppressed the secretion of pro-inflammatory cytokines induced by C. albicans by targeting NF-κB p65 and B cell leukemia/lymphoma 10 (BCL-10). Conclusions In conclusion, up-regulated miR-155 acts as a negative feedback regulator in the innate immune response against C. albicans infection. 2019 Annals of Translational Medicine.

Methods One hundred patients aged >65 years were randomly allocated into either the PEEP5 or the electrical impedance tomography (EIT) group (PEEPEIT). Each group underwent volume-controlled ventilation (tidal volume 6 mL/kg predicted body weight) with the PEEP either fixed at 5 cmH2O or set at an individualized EIT setting. The primary endpoint was the ratio of the arterial oxygen partial pressure to the fractional inspired oxygen (PaO2/FiO2). The secondary endpoints included the driving pressure, and dynamic respiratory system compliance (Cdyn). Other outcomes, such as the mean airway pressure (Pmean), mean arterial pressure (MAP), lung complications and the length of hospital stay were explored. Results The optimal PEEP set by EIT was significantly higher (range from 9-13 cmH2O) than the fixed PEEP. PaO2/FiO2 was 47 mmHg higher (95% CI 7-86 mmHg; P=0.021), Cdyn was 4.3 mL/cmH2O higher (95% CI 2.1-6.7 cmH2O; P less then 0.001), and the driving pressure was 3.7 cmH2O lower (95% CI 2.2-5.1 mmH2O; P less then 0.001) at 0.5 h during one-lung ventilation (OLV) in the PEEPEIT group than in the PEEP5 group. At 1 h during OLV, PaO2/FiO2 was 93 mmHg higher (95% CI 58-128 mmHg; P less then 0.001), Cdyn was 4.4 mL/cmH2O higher (95% CI 1.9-6.9 mL/cmH2O; P=0.001), and the driving pressure was 4.9 cmH2O lower (95% CI 3.8-6.1 cmH2O; P less then 0.001) in the PEEPEIT group than in the PEEP5 group. PaO2/FiO2 was 107 mmHg higher (95% CI 56-158 mmHg; P less then 0.001) in the PEEPEIT group than in the PEEP5 group during double-lung ventilation at the end of surgery. Conclusions PEEP values determined with EIT effectively improved oxygenation and lung mechanics during one lung ventilation in elderly patients undergoing thoracoscopic surgery. 2019 Annals of Translational Medicine.

Methods In vivo the effect of catalpol (2.5, 5, 7.5 mg/kg; i.p) or vehicle administered 24 h after stroke and then daily for 7 days on behavior, Map-2+/p-S6+ and Map-2+/GAP-43+ immunofluorescence were assessed in a rat model of stroke. Then in vitro, an oxygen-glucose deprivation (OGD/R) model was established to observe the effect of catalpol (0.1, 1, 10 and 100 µg·mL-1) on cultural neurons survive rate, neuronal cell activity and axon growth. Moreover, rapamycin (Rapa) was used to inhibit the mTOR pathway to observe the catalpol mechanism on neuronal cell activity to promote axonal growth, and the proteins related with PI3K/AKT/mTOR pathway were detected by Western blot assay. Results Repeated treatments with catalpol improved neurological score and significantly enhanced neuronal cell activity, then promote axonal regeneration after stroke. While in vitro, catalpol also increased the survive rate and axonal growth of the neurons. Catalpol can reversed the Rapa inhibited effects on neurons' survive and axon extending. Catalpol can also reversed proteins reduced by Rapa related with PI3K/AKT/mTOR pathway. Conclusions These results suggested that catalpol might contribute to internal neuronal cell activity and axonal regeneration by regulating PI3K/AKT/mTOR pathway. 2019 Annals of Translational Medicine.
