Diagnosis of sphenoid sinus disease is very difficult because the location of sinus is deep and hidden within the skull and the symptoms of sphenoiditis are nonspecific. However, thanks to new technologies in imaging (CT and MRI) and nasal endoscopy, the literature on sphenoid sinus fungus ball have been published more. But all of the SSFB which have been reported are isolated or unilateral. We reported one rare case of bilateral sphenoid sinus fungus balls. This patient was treated in our department. Headache was the only symptom in this case. The patient was treated by sphenoidotomy via endoscopic approach and removal both of the lesions. No recurrence was found after 6-months follow-up.

Objective:To explore the expression and location of TLR5 and NLRC4 on different breast cancer cell lines MDA-MB-231,MCF-7 and MDA-MB-435 and TLR5 activation in breast cancer cell line by recombinant flagellin . Methods:The mRNA level of TLR5 and NLRC4 in MDA-MB-231, MCF-7 and MDA-MB-435 cell were detected with quantitative Real-time PCR and TLR5 expression and location in MDA-MB-231 and MCF-7 cell were detected with Flow cytometry. Induction,expression,purification and i-dentification of recombiant flagellin,including FliC (activating both TLR5 and NLRC4),FliC△90-97(unable to activate TLR5),FliC-L3A (unable to activate NLRC4),FliC△90-97:L3A (unable to activate both TLR5 and NLRC4). 1 μg/ml recombinant flagellin were used to stimulate MCF-7 cell lines,12 h later,the supernate were collected,and ELISA was performed to assess the secretion of IL-8. Results:The mRNA level of TLR5 in MCF-7 cell was 1 700 folds higher than that of MDA-MB-435. TLR5 was expressed in MCF-7 cell surface and ctyosol,while expressed only in cytosol in MDA-MB-231 cell. FliC and FliC-L3A,which were able to activate TLR5 pathway,stimualted MCF-7 cell line to secret IL-8,but FliC△90-97 and FliC△90-97:L3A did not. Conclusion:TLR5 and NLRC4 have been expressed in different breast cancer lines,but there exists difference on the expression level and location of TLR5. Expression level of TLR5 and NLRC4 in MCF-7 cell were higher than other breast cancer lines. TLR5 receptor which is expressed on the surface of breast cancer cell can be activated by flagellin,and these work also provide us experimental basis to further understand the impact of TLR5 activation on breast cancer cell proliferation.

Objective:To investigate the correlation between inositol level and glycolipid metabolism in gravidas with gestational diabetes mellitus (GDM).Methods:A cross-sectional study was conducted on 80 GDM cases undergoing routine examination at Fujian Provincial Maternity and Children's Hospital from November 2018 to August 2019, who were selected as GDM groups. Another 50 women with uncomplicated pregnancies during the same period were selected as the control group. Blood and urine inositol level and serum glycolipid profiles were compared between the two groups, and their association was analyzed. Independent or paired-sample t test, Mann-Whitney test, Chi-square (or Fisher's exact) test, and Pearson correlation test were performed for statistical analysis. Results:The serum inositol concentration and high-density lipoprotein (HDL) cholesterol in the GDM group were significantly lower [322.1 ng/ml (279.1-364.1 ng/ml) vs 403.8 ng/ml (391.8-425.3 ng/ml), Z=-7.879; 1.8 mmol/L (1.5-2.0 mmol/L) vs 2.0 mmol/L (1.7-2.2 mmol/L), Z=-2.419; both P<0.05], while the concentration of urine inositol, lipoprotein-a (lipo-a), 0 h-, 1 h-, 2 h-oral glucose tolerance test (OGTT) glucose, fasting insulin, and glycosylated hemoglobin (HbA1c) were significantly higher when comparing to the control group [192.2 ng/ml (171.0-219.9 ng/ml) vs 143.8 ng/ml (121.1-158.6 ng/ml), Z=-6.834; 253.2 mg/L (65.0-349.0 mg/L) vs 148.5 mg/L(46.5-159.3 mg/L), Z=-0.187; 5.0 mmol/L (5.1-5.6 mmol/L) vs 4.4 mmol/L (4.2-4.6 mmol/L), Z=-5.547; 10.0 mmol/L (9.1-11.3 mmol/L) vs 7.8 mmol/L (7.0-8.4 mmol/L), Z=-6.987; 8.6 mmol/L(7.6-9.4 mmol/L) and 6.6 mmol/L (5.7-7.1 mmol/L), Z=-7.100; 18.2 mU/L(10.6-25.9 mU/L) vs 11.0 mU/L (6.3-12.7 mU/L), Z=-4.537; 5.4%(4.5%-5.5%) vs 5.1%(4.9%-5.4%), Z=-3.468; all P<0.05]. (2) Serum inositol concentration was negatively correlated with fasting insulin and 0 h-, 1 h-, 2 h- OGTT glucose level ( r=-0.386, -0.416, -0.350 and -0.407, respectively); urinary inositol concentration was positively correlated with 0 h-, 1 h-, 2 h-OGTT glucose levels ( r=0.402, 0.389 and 0.429, respectively) (all P<0.05). Conclusions:Serum inositol concentration was decreased, and urinary inositol excretion was increased in women with GDM. Measurement of changes in inositol levels during the second trimester may be helpful to assess the metabolic status of pregnant women.
