Furthermore, RT-qPCR results indicated that IL-1β increased osteogenic gene expression within this concentration range. Moreover, Western blotting results identified that the bone morphogenetic protein/Smad (BMP/Smad) signaling pathway was significantly activated by IL-1β under osteogenic conditions. Therefore, the present results suggested that within a certain concentration range, IL-1β promoted osteogenic differentiation and function of MBMMSCs via the BMP/Smad signaling pathway.The aim of the present study was to identify whether lumbar spinal subtypes (LSS) were associated with lumbar disc degeneration (LDD) among asymptomatic middle-aged and aged subjects. A cohort of 158 asymptomatic Chinese adults aged >40 years was recruited and 97 volunteers that met the inclusion criteria with complete information available were selected for inclusion. According to spinal morphology, volunteers were divided into four subtypes based on the classification of Roussouly. After baseline information was collected and spinopelvic parameters were measured, the data were compared among the four groups. According to the Pfirrmann classification, the degree of LDD was evaluated at each level on the MRI. For grades I-V, LDD at each level was effectively compared. Each of the four LSS from I to IV according to Roussouly classification from types I to IV were comprised of 25 (25.8%), 19 (19.6%), 38 (39.2%) and 15 (15.5%) of volunteers, respectively. Lumbar lordosis, sacral slope and pelvic incidence were significantly different among the four sub-types (P less then 0.001 for each), but no difference in pelvic tilt was observed (P=0.21). From types I to IV LSS, the proportion of disc degeneration was found to be 44, 52, 50 and 48%, respectively, which exhibited no statistically significant difference among LSS. No correlation between LSS and intervertebral disc degeneration was obtained among the asymptomatic middle-aged and aged subjects. The present study provides a reference for spinal surgery and indicated that additional risk factors should be assessed in the asymptomatic population of this age group, particularly in terms of differentially expressed genes.In pre-surgical patients with chronic rhinosinusitis with nasal polyps (CRSwNPs), positive findings on computed tomography (CT) scans and an exacerbation of symptoms are two possible factors that indicate surgery. However, the relationship between these factors remains unclear. Confirmed CRSwNP patients ready for sinus surgery were consecutively enrolled. The Sino-Nasal Outcome Test 22 (SNOT-22) and visual analog scale (VAS) scoring were completed by these patients, and scores were subjected to factor analysis using a principal component analysis (PCA) to evaluate subjective symptom components related to CRS. Patient CT scores, measured by the Lund-Mackay score (LMS), together with their demographics, medical treatment, and atopy status, were collected and analyzed. A total of 288 patients who met the criteria for CRSwNP and underwent CT scanning prior to surgery in the Eye, Ear, Nose, and Throat Hospital of Fudan University were enrolled. Five components were identified from the PCA of the SNOT-22 results and VAS scores related to subjective symptoms. selleck chemical More severe 'nasal' symptoms (P=0.03; 95% CI, 0.092-1.824), loss of smell and taste (P2.59 compared with patients with E/M ratios less then 2.59. Loss of smell and taste alone was correlated with the LMS in patients with highly positive CT scores. The present study demonstrated associations between several subjective symptoms and objective severity in preoperative CRSwNP patients. Nasal symptoms, including olfaction loss, were correlated positively with CT scores, while ocular- and pain-related symptoms showed an opposite pattern. However, this relationship was not confirmed in patients with highly positive CT scores. A subset analysis confirmed, in terms of symptoms, the value of the E/M ratio for indicating eosinophilic chronic rhinosinusitis.The present study aimed to explore the clinical characteristics and management of retroperitoneal hematoma (RPH) after invasive intervention during a 12-year period in China. A retrospective review of patients with RPH after various invasive interventions was conducted at the China National Center for Cardiovascular Diseases. A total of 42 patients with a mean age of 63.1±2.5 years were continuously recruited in the study between January 2007 and September 2018. The incidence, manifestations and management of RPH were analyzed. A total of 20 patients had punctures in the femoral arterial access under the inguinal ligament and 5 patients had punctures above the inguinal ligament. The majority of RPH occurred within 24 h after intervention, while some occurred after postoperative 24 h. Pain was the most common symptom in patients with RPH. All patients who underwent intervention presented a reduction in hemoglobin (HB) concentration. The overall incidence of nosocomial infection was 38.1% and mortality was 7.1%. The findings demonstrated that RPH is a rare complication after invasive intervention of cardiovascular diseases with non-specific clinical manifestations. The reduction of HB concentration was a vital manifestation for RPH. Most RPH cases could be treated by conservative treatment and blood transfusion. A puncture in the femoral arterial access under the inguinal ligament may result in RPH.Acute kidney injury (AKI) stage I is the most common stage of AKI observed among patients who underwent cardiac surgery with cardiopulmonary bypass (CPB). The relationship between AKI stage I and mortality requires further investigation. Patients aged 18 years or older who underwent cardiac surgery with CPB between July 1, 2013 and May 31, 2014, were reviewed in the present study. Patients were dichotomized into i) The AKI stage I group, and ii) the non-AKI group. The primary measured characteristic in the present study was the relationship between AKI and mortality. Kaplan-Meier survival analyses were taken to obtain survival curves. A total of 1,846 patients were included in this present study. The mean age was 51.76±13.56 years. A total of 1,508 patients did not develop AKI and 338 developed AKI stage I. The mean follow-up period among survivors was 9.95±3.45 months. Kaplan-Meier survival analyses showed that patients with AKI stage I were at an increased mortality risk (P less then 0.0001). In multivariate Cox regression analysis, AKI stage I remained independently associated with a reduced survival.
