Background: Apolipoprotein A-I (ApoA-I) is a key cardioprotective lipoprotein. Nevertheless, it remains unclear how ApoA-I relates to ischemic risk across glucose metabolism statuses in patients with coronary artery disease (CAD). This study investigated whether glucose metabolism status influences the association between ApoA-I and ischemic risk in CAD patients. Methods: This cohort study included 10,724 consecutive CAD patients undergoing percutaneous coronary intervention, who were classified into diabetes mellitus (DM), pre-DM, and normal glucose regulation (NGR) groups. The primary clinical endpoint was major adverse cardiac and cerebrovascular event (MACCE), defined as a composite of all-cause death, myocardial infarction, revascularization, and stroke. Results: Of the 10,232 patients ultimately included, 2,139 (20.9%) experienced MACCE over 5 years. A significant interaction was observed between ApoA-I levels and glucose metabolism status (P for interaction=0.041). In the DM group, an L-shaped association between ApoA-I and MACCE was found, with lower ApoA-I levels linked to a higher risk of MACCE (P for non-linearity= 0.044). Multivariate Cox regression analysis showed that patients in the lowest quintile of ApoA-I had a 1.327-fold increased risk of MACCE compared to those at the lowest risk (hazard ratio, 1.327; 95% confidence interval, 1.097 to 1.604). However, no significant association was observed in the pre-DM or NGR groups (both P>0.05). Conclusion This large-scale, 5-year follow-up study is the first to demonstrate that lower ApoA-I levels are associated with increased MACCE risk in CAD patients with DM, highlighting the potential value of ApoA-I in risk stratification and as a therapeutic target.

Objective: To improve the accuracy of diagnosis and to reduce the misdiagnosis rate of nasopharyngeal carcinoma by analyzing the characteristics of such masses. Methods: Clinical data from 55 patients with suspicion of nasopharyngeal carcinoma diagnosed and treated between March 2016 and September 2017 were analyzed. All patients were followed up regularly. Results: With following-up of 12 to 25 months, 6 (10.9%) of 55 cases were identified as nasopharyngeal malignant tumors, including 4 cases of nasopharyngeal carcinoma and 2 cases of lymphoma, and 49 cases (89.1%) were diagnosed with nasopharyngeal benign masses, including 29 (59.2%) cases for nasopharyngeal lymphoid proliferation, 15 (30.6%) for adenoid hypertrophy, 2 (4.1%) for nasopharyngeal cyst, 1 (2.0%) for polyp, 1 for papilloma and 1 for nasopharyngeal pharyngeal cyst. Small nasopharyngeal malignant tumor and masses with benign hyperplasia showed the overlap of images on the enhanced MRI/CT and Fibro-nasopharyngoscopy, but all 6 patients with nasopharyngeal malignant tumors presented with moderately enhanced multiple enlarged lymph nodes. Conclusions Fibro-nasopharyngoscopy and enhanced MRI/CT have some value on evaluation of nasopharyngeal masses, but biopsy is a golden standard for diagnosis. Follow-up is necessary for the patients with negative biopsy and benign nasopharyngeal hyperplasia indicated by fibro-nasopharyngoscopy and enhanced MRI/CT.

Objective To explore the safety and cosmetic effect of nipple-sparing modified radical mas tectomy and immediate tissue expander implantation with single circumaereolar incision.Methods 30 patients were enrolled in Peking Union Medical College Hospital between Jan.2014 and Dec.2015.All the patients were categorized according to surgical incision (single circumaereolar incision group vs double incisions group).Data on clinicopathological parameters,average hospital stay,complications and overall cosmetic effect were retrospectively collected.Data was performed with Chi-square test,Fisher exact test and t-test.Statistical significance was defined as P＜0.05.Results 19 patients were enrolled in single circumaereolar incision group,and 11 patients in double incisions group.There was no significant difference for operation duration (P=0.093) and average hospital stay (P=0.339).After follow-up for 19.1 months,ranging from 8 to 31 months,no patients developed seroma or arm lymphedema.There was no statistical significance between the two groups in terms of sensation in nippleaereolar area (P=0.973),bilateral symmetry (P=0.650) and overall cosmesis (P=0.483).Conclusion single circumaereolar incision nipple-sparing modified radical mastectomy and immediate tissue expander implantation can be one of the preferable surgical procedures with benefits of minimal invasiveness,reliable oncological safety and decent cosmetic effect.
