Objective To investigate the therapeutic effect of nasal endoscope surgery on chronic sinusitis and nasal polyps in geriatric patients.Methods A total of 132 geriatric patients with chronic sinusitis and nasalpolyps underwent nasal endoscope surgery in our hospital from Jun.2010 to Jun.2014,and the therapeutic effect was investigated.Results In the 132 cases,92 cases were cured (69.7%).Therapeutic effects were excellent in 33 cases (25.0%),and invalid in 7 cases (5.3%).The total effective rate was 94.7%.The total effective rate was 100.0% in type Ⅰ,97.4% in type Ⅱ and 84.8% in type Ⅲ.The total effective rate was higher in type Ⅰ and Ⅱ than in type Ⅲ (x2=3.506 and 6.218,P=0.035 and 0.012).Local complications occurred in 10 cases (7.6%),including 1 case with nasolacrimal duct injury,2 cases with orbital hematoma,5 cases with nasal adhesion,1 case with surgical cavity hemorrhage and 1 case with sinus atresia.Conclusions The therapeutic effects of nasal endoscopesurgery on chronic sinusitis and nasalpolyps are good in geriatric patients,especially in treating chronic sinusitis and nasalpolyps of type Ⅰ and Ⅱ,and the postoperative complications are less,which is worth clinical application.

Objective To investigate the value of S-Detect classification in differential diagnosis of breast mass . Methods The data of forty-seven patients with breast mass lesions ( n=61) from our hospital during January to December in 2016 were retrospectively analyzed . Both the man-made BI-RADS classification ( identified by three different specialist physicians with 2 ,5 and 7 years of experience , respectively) and computer S-Detect classification were performed . The sensitivity ,specificity ,accuracy , positive predictive value and negative predictive value of the man-made BI-RADS classification and S-Detect classification of the benign or malignant diagnosis of breast lumps were calculated . The ROC curve was further plotted ,and the area under the curve ( AUC) of each group was compared ,respectively . Results Sixty-one breast mass lesions were confirmed 36 benign lesions and 25 malignant lesions by pathological biopsy . The sensitivity ,specificity and accuracy of man-made BI-RADS classification were as follows:2-year experience physicians 69 .4% ,72 .0% and 70 .5% ;5-year experience physicians:64 .0% ,92 .0% and 75 .4% ;7-year experience physicians:69 .4% , 92 .0% and 78 .7% . The diagnostic sensitivity , specificity , and accuracy of S-Detect classification were 80 .6% ,96 .0% and 86 .9% . The specificity ,accuracy and positive predictive value of S-Detect classification were significantly higher than those of 2-year experience physicians by BI-RADS classification ( P <0 .05) . The area under the ROC curve of each group was 0 .729 ,0 .786 and 0 .801 for 2 , 5 and 7-year experience physicians , respectively , and 0 .917 for S-Detect classification . Conclusions Compared with the man-made BI-RADS classification ,S-Detect classification has advantages in diagnosis of the benign or malignant of breast mass and is helpful to improve the accuracy of diagnosis , especially for junior physicians .

Background:
Gut microbiota is closely related to the occurrence and development of diabetes and affects the prognosis of diabetic complications, and the underlying mechanisms are only partially understood. We aimed to explore the possible link between the gut microbiota and vascular inflammation of diabetic mice.
Methods:
The db/db diabetic and wild-type (WT) mice were used in this study. We profiled gut microbiota and examined the and vascular function in both db/db group and WT group. Gut microbiota was analyzed by 16s rRNA sequencing. Vascular function was examined by ultrasonographic hemodynamics and histological staining. Clostridium butyricum (CB) was orally administered to diabetic mice by intragastric gavage every 2 days for 2 consecutive months. Reactive oxygen species (ROS) and expression of nuclear factor erythroid-derived 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) were detected by fluorescence microscopy. The mRNA expression of inflammatory cytokines was tested by quantitative polymerase chain reaction.
Results:
Compared with WT mice, CB abundance was significantly decreased in the gut of db/db mice, together with compromised vascular function and activated inflammation in the arterial tissue. Meanwhile, ROS in the vascular tissue of db/db mice was also significantly increased. Oral administration of CB restored the protective microbiota, and protected the vascular function in the db/db mice via activating the Nrf2/HO-1 pathway.
Conclusion
This study identified the potential link between decreased CB abundance in gut microbiota and vascular inflammation in diabetes. Therapeutic delivery of CB by gut transplantation alleviates the vascular lesions of diabetes mellitus by activating the Nrf2/HO-1 pathway.
