Unilateral lingual nerve and hypoglossal nerve injury caused by a novel laryngeal mask airway: a case report

Abstract Cranial nerve injury by a laryngeal mask airway is rare but a serious complication. The nerve injuries must be prevented during the intubation using a laryngeal mask airway. We report a female patient who complained of tongue numbness, slurred speech, and slight difficulty in swallowing solid food after a hand surgery. She was then diagnosed with unilateral lingual nerve and hypoglossal nerve injuries. Extreme head rotation, relatively small oral cavity, and wide rigid composition at the lower part of the novel laryngeal mask probably resulted in cranial nerve injury.

Study on the correlation between eosinophils and chronic rhinosinusitis with nasal polyps in Xinjiang region of China / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the correlation between eosinophils (Eos) and the incidence of chronic sinusitis with nasal polyps (CRSwNP) in Xinjiang region of China by comparing the proportion of inflammatory cells in the pathological tissues and peripheral blood. Methods: Retrospective analysis was performed on 582 patients with CRSwNP who underwent endoscopic nasal surgery in the First Affiliated Hospital of Xinjiang Medical University from January 2012 to March 2018, including 367 males and 215 females, aged (45.5±13.4) years (x¯±s). Patients were divided into groups according to demographic characteristics, recurrence and complication of allergic rhinitis (AR). Preoperative blood routine and postoperative pathological section data of nasal polyps were collected to compare the ratio of inflammatory cells in pathological tissue and the ratio of peripheral blood Eos in each group. The correlation between the proportion of inflammatory cells in the pathological tissue of nasal polyps and the recurrence of CRSwNP was analyzed, as well as the distribution of (eosCRSwNP) in Uygur and Han CRSwNP patients in Xinjiang region. Statistical analysis was performed by SPSS 19.0 software. Results: Compared with non-recurrent CRSwNP patients, the ratio of Eos in nasal polyp tissue and peripheral blood was increased significantly, (Z value was -3.142 and -2.344, respectively, both P<0.05). Compared with CRSwNP patients without AR, the ratio of Eos in nasal polyps and peripheral blood was also increased significantly in patients with AR (Z value was -6.664 and -4.520, respectively, both P<0.05). There was a positive correlation between tissue Eos and CRSwNP recurrence (r=0.130, P=0.002). The majority of CRSwNP patients were both eosCRSwNP in Uygur and Han ethnic groups. Conclusions: Eos is associated with the recurrence of CRSwNP in Xinjiang region, and eosCRSwNP is the dominant factor in both Uygur and Han patients.

Silencing of circular RNA ANRIL attenuates oxygen-glucose deprivation and reoxygenation-induced injury in human brain microvascular endothelial cells by sponging miR-622

BACKGROUND: Circular RNA (circRNA) is highly expressed in the brain tissue, but its molecular mechanism in cerebral ischemia-reperfusion remains unclear. Here, we explored the role and underlying mechanisms of circRNA antisense non-coding RNA in the INK4 locus (circ_ANRIL) in oxygen-glucose deprivation and reoxygenation (OGD/R)-induced cell injury. RESULTS: The expression of circ_ANRIL in OGD/R-induced human brain microvascular endothelial cells (HBMECs) was significantly up-regulated, while that of miR-622 was significantly down-regulated. Overexpression of circ_ANRIL significantly inhibited the proliferation of OGD/R-induced HBMECs and aggravated OGD/R-induced cell apoptosis. Moreover, circ_ANRIL overexpression further increased the secretion of interleukin (IL)-1ß, IL-6, tumor necrosis factor-a, and monocyte chemoattractant protein-1 in OGD/R-treated HBMECs. The results of bioinformatics analysis and luciferase reporter assay indicated that circ_ANRIL served as an miR-622 sponge to negatively regulate the expression of miR-622 in OGD/R-treated HBMECs. Additionally, circ_ANRIL silencing exerted anti-apoptotic and anti-inflammatory effects by positively regulating the expression of miR-622. Furthermore, inhibition of OGD/R-induced activation of the nuclear factor (NF)-kB pathway by circ_ANRIL silencing was significantly reversed by treatment with miR-622 inhibitor. CONCLUSIONS: Knockdown of circ_ANRIL improved OGD/R-induced cell damage, apoptosis, and inflammatory responses by inhibiting the NF-κB pathway through sponging miR-622.

Methods The mouse macrophage RAW264.7 cells induced by RANKL was used alone as the control group, different concentrations of par-thenolide (0.5, 1, 2 μmol/L) were added to culture the RAW264.7 cells. On the third, fifth and seventh day, the tartrate resistant acid phosphatase (TRAP) staining method was used to detect osteodast-like cells and the cell number was count;the contents of tartrate resistant acid phosphatase (TRAP5b) in the Culture supernatant of each groups were detected by enzyme linked immunosorbent assay (ELISA) and the expression of osteodast marker gene alcitonin receptor (CTR) and matrix metalloproteinase (MMP)-9 in each groups were detected by realtime-polymerase chain reaction (PCR) on the seventh day. We use Chi-square test and t test to test the differences between groups by SPSS 17.0. Results In different culture conditions, RANKL could always induce the RAW264.7 cell differentiate into mature osteoclasts. Compared with the control group at the same time control group, on the third, fifth and seventh day, he number of mature osteoclasts induced were obviously decreased in groups adding different concentration of PAR; the number of induced osteoclasts decreased along with the increase of parthenolide concentration, on the seventh day in 0.5, 1, 2 μmol/L concentration PAR groups, the number of mature osteoclasts compared with the control group were descended 36.3%, 40.8%, 49.3%(t=7.758, 8.742, 10.56;P<0.05);the contents of TRAP5b in the culture supernatant were consistent with the cell counting results on the seventh day (P<0.05). The expression of CTR and MMP-9 by TRAP positive osteoclasts decreased along with the increase of parthenolide concentration, and the 2 μmol/L group was the lowest. Compared with the control group, there were statistically significant differences with the different PAR concentration groups 0.5, 1, 2 μmol/L (P<0.05). Conclusion Parthenolide can inhibit RANKL induced RAW264.7 differentiation into osteoclast cells, and the inhibition is dose dependent.
