Objective To explore the CT findings of mucoepidermoid carcinoma (MEC) of the tracheobronchial tree and improve the diagnostic accuracy. Methods The CT images, histopathological and clinical data in 24 patients with pathologically proved MEC of the tracheobroncbial tree were retrospectively analyzed. Results The clinical symptoms included cough, sputum, fever, wheezing, chest pain and hemoptysis. The patient was proved to be low-grade (n=19) and high-grade (n=5) MEC histopathologically. One lesion was located in trachea, 6 in main bronchus, 12 in lobar bronchus and 5 in segmental, subsegmental and distal bronchus. The tumor presented as no-invasive endotracheobronchial well-defined round-like nodule (n=13, locating in lobar and higher bronchus) and columnar sharp (n=3, locating in main bronchus), or intra-and-extraluminal well-defined round-like nodule or mass (n=6, locating in lobar and lower bronchus) and irregular mass with invasive pattern (n=2, high-grade type). The density of lesion was similar to the muscule and the calcification within lesion was showed in 4 patients on non-enhanced CT. The lesion had marked enhancement in 17 patients on enhanced CT. Obstructive changes were found in 20 patients. Conclusion MEC of the tracheobronchial tree is usually low-grade malignancy and locates in main and lobar bronchus with no-invasive well-defined airway mass, marked enhancement and calcification on CT.

With patients' general situation, medication use, occurrence time of adverse drug reaction/event (ADR/ADE), clinical manifestations and prognosis as reference items, a retrospective study was made for 315 cases with ADR/ADE induced by Gastrodin in Chongqing from January 2008 to June 2014, in order to analyze the characteristics of ADR/ADE and provide reference for rational clinical medication. The results showed that among the 315 cases with ADR/ADE, 143 cases (45.4%) were males and 172 cases (54.6%) were females, most of them (74.9%) were aged above 45; 60 cases (19.0%) with ADE were caused by off-label indications and 66 cases (21.0%) with ADE were caused by over dosage; ADR/ADE cases induced by intravenous drip mainly happened within 30 min (85.5%), ADR/ADE cases induced by oral administration mainly happened within 2 h (74.4%), and all of ADR/ ADE cases induced by intramuscular injection happened within 10 min. Totally 593 ADR/ADE cases were reported, which were mainly damages in gastrointestinal system, skin and its adnexa; And 61.9% of ADR/ADE cases were newly reported. It is suggested that medical workers shall learn about the regularity and characteristics of ADR/ADE induced by gastrodin, apply it in clinic with standards, pay close attention to changes of patients' situations and attach importance to the monitoring of ADR/ADE, so as to enhance the safety of medication.

BACKGROUND:Ethyl linoleate has been proved to attenuate the inflammatory-cytokines release induced by lipopolysaccharide, but whether it can inhibit titanium-induced osteolysis and the underlying mechanism remain unclear. OBJECTIVE:To observe the effect of ethyl linoleate on the expression of inflammatory-related factors induced by titanium particles and explore its mechanism. METHODS:Forty-eight Kunming mice were randomly divided into blank control, titanium, dimethylsulfoxide (DMSO) and experimental groups. The back air pouch Inflammatory models were established in the mice of the titanium, DMSO and experimental groups, in which the 200 μL menstruum of DMSO (0.5%) and 200 μL ethyl linoleate (0.5%) were respectively administered into the pouch of the mice at 12 hours. Mice in the blank control group received no intervention. Fourteen days later, the inflammatory cel infiltration in the skin was examined through hematoxylin-eosin staining;the expression levels of inhibitorκB-α, nuclear factor-κB, inducible nitric oxide synthase, cyclooxygenase-2, tumor necrosis factor-αand interleukin-6 as wel as ERK, p-ERK, JNK, p-JNK, p38 and p-p38 in MAPK signaling pathways were evaluated by western blot assay. RESULTS AND CONCLUSION:In the titanium group and DMSO group, there were numerous inflammatory cel s and vacuole-like necrotic tissues in the hair fol icle lacuna of dermis and loose connective tissues of hypodermis. The experiment group showed significant reduction in inflammatory cel infiltration and vacuole-like necrosis. Compared with the blank control group, the expression levels of inducible nitric oxide synthase, cyclooxygenase-2, nuclear factor-κB, tumor necrosis factor-α, interleukin-6, ERK, JNK and p38 in the DMSO and titanium groups were significantly increased, while inhibitorκB-αsignificantly decreased (P<0.05). Compared with the DMSO and titanium groups, there were significantly down-regulated levels of inducible nitric oxide synthase, cyclooxygenase-2, nuclear factor-κB, tumor necrosis factor-α, interleukin-6, ERK, JNK and p38, and up-regulated inhibitorκB-αlevel in the experimental group (P<0.05). In conclusion, ethyl linoleate can remarkably suppress the expressions of titanium-induced inflammatory factors associated with the inhibition of nuclear factor-κB and MAPK signaling pathway activation.

BACKGROUND:Kinesio taping is commonly used,but there is a lack of rigorous and scientific research,especially in biomechanics and exercise.OBJECTIVE:To overview the biomechanics characteristics of the ankle joint after treatment with kinesio taping,and to summarize the biomechanics difference in kinematics,kinetics,and electromyography of the ankle joint between non-kinesio and kinesio taping.METHODS:Ovid Medline,Elsevier SDOL,PubMed and CNKI databases were retrieved for the Chinese and English literatures concerning the biomechanics and exercise performance of kinesio taping published before December 2015.Subsequently,all literatures were classified according to the Oxford Centre for Evidence-based Medicine Levels of Evidence.RESULTS AND CONCLUSION:Most of literatures support the viewpoint that kinesio taping can improve ankle joint stability,increase the arch height and decrease the external load of key muscles of the ankles and feet.Some studies have suggested that during landing,kinesio taping shortened the duration of the peak of support reaction forces,reduced the flexion force,and increased the loading rate of lower extremities,thereby resulting in an increased risk for injury.Other studies have shown that kinesio taping increases the recruitment of motor units and changes the order of neuromuscular contraction,but it cannot improve the athletic performance,and even decrease the athletic performance in most cases.Whether kinesio taping improves muscular force,increases the muscular performance,and increases the power of lower extremities is under discussion;hence,in-depth studies are needed in the future.

OBJECTIVETo identify the predictors of the positive results of transrectal ultrasound (TRUS)-guided biopsy for prostate cancer.

METHODSWe performed univariate and multivariate logistic regression analyses on the relevant data on 385 male patients that underwent TRUS-guided biopsy for prostate cancer, including such potential predictors as age, body mass index (BMI), symptoms, results of digital rectal examination (DRE), tPSA, fPSA, free/total PSA ratio (f/tPSA), prostate volume (PV), and PSA density (PSAD) for identification of the risk factors related to the positive rate of biopsy. Then we constructed a scoring system as a tool for predicting prostate cancer in repeat biopsies and determined the sensitivity of the system by calculating the false positive rate using the receiver operating characteristic curve.

RESULTSAmong the 385 patients, 139 (36.1%) were diagnosed with prostate cancer. On multivariate analysis, age (P < 0.01), DRE (P < 0.01), tPSA (P < 0.01), fPSA (P < 0.01), f/tPSA (P < 0.01), PV (P < 0.01), and PSAD (P < 0.01) were all significant predictors of prostate cancer. Multivariate logistic regression analysis showed age, tPSA, f/tPSA, PV, and PSAD to be independent predictors, with ORs and 95% CIs of 1.07 (1.05-1.16), 1.05 (1.02-1.15), 0.97 (0.86-0.99), 0.98 (0.87-0.96), and 1.79 (1.48-2.06), respectively. Moreover, patients with the risk score of 3-5 had a significantly higher rate of prostate cancer than those with 0-2 (64% vs 11%, P < 0.001).

CONCLUSIONThe scoring system on the key predictors of prostate cancer can help urologists to identify the men in need of prostatic biopsy.

Obstructive nephropathy ultimately leads to end-stage renal failure. Renovascular lesions are involved in various nephropathies, and most renal diseases have an ischemic component that underlies the resulting renal fibrosis. The aim of this study was to investigate whether morphological changes occur in the renal vasculature in hydronephrosis and the possible mechanisms involved. A model of complete unilateral ureteral obstruction (CUUO) was used. Experimental animals were divided into five groups: a normal control group (N) and groups of animals at 1st week (O1), 2nd week (O2), 4th week (O4) and 8th week (O8) after CUUO. Blood pressure was measured, renal arterial trees and glomeruli were assessed quantitatively, and renovascular three-dimensional reconstruction was performed on all groups. Glomerular ultrastructural changes were examined by transmission electron microscopy. The results showed that the systolic blood pressure was significantly increased in the obstructed groups (O1, O2, O4 and O8). Three-dimensional reconstruction showed sparse arterial trees in the O8 group, and a tortuous and sometimes ruptured glomerular basement membrane was found in the O4 and O8 groups. Furthermore, epithelial media thickness and media/lumen ratio were increased, lumen diameters were decreased, and the cross-sectional area of the media was unaltered in the segmental renal artery, interlobar artery and afferent arterioles, respectively. In conclusion, renal arterial trees and glomeruli were dramatically altered following CUUO and the changes may be partially ascribed to vascular remodeling. Elucidation of the molecular mechanisms of renovascular morphological alterations will enable the development of potential therapeutic approaches for hydronephrosis.
