Objective To investigate the safety and efficacy of embolization of inferior phrenic artery as nonbronchial systemic artery(NBSA) for hemoptysis.Methods Imaging and clinical data of 1 1 patients with inferior phrenic artery as NBSA were analyzed retrospectively, and complications and hemoptysis recurrence rate were recorded.Results Seven patients underwent enhanced CT examination and 4 patients underwent plain CT examination before embolization.Six of those patients who underwent enhanced CT examination were found abnormal arteries,and were confirmed as NBSA by angiography.The other 5 patients were found unmatch of lesion distribution and bronchial arteries during procedure,and inferior phrenic artery as NBSA were found by expanding angiography.All procedure were successfully performed,3 cases occurred hiccup and need not treatment.No serious complications occurred,such as incontinence and paraplegia.During (1 8.7 ± 1 3.8)months follow-up,only 1 patient recurrence of hemoptysis,and successful after conservative treatment,and the other 10 patients had no recurrence of hemoptysis.Conclusion The inferior phrenic artery as NBSA can induce hemoptysis.It is safe to embolization of the inferior phrenic artery,which can reduce the recurrent rate of hemoptysis.

Objective:To explore the application effect of group guidance based on intelligent communication matrix in patients with type 2 diabetes mellitus (T2DM) .Methods:Using the convenient sampling method, a total of 60 T2DM patients with poor self-management ability who scored less than 19.6 on Summary of Diabetes Self Care Activities (SDSCA) in the Affiliated Chuzhou Hospital of Anhui Medical University were selected as the research objects from May to June 2020. They were randomly divide into the observation group ( n=30) and the control group ( n=30). The observation group was given continuous group guidance based on intelligent communication matrix, while the control group was given routine health guidance. The SDSCA score, body mass index and glycosylated hemoglobin (HbA1c) before and after intervention were compared between the two groups. Results:After intervention, the SDSCA score of the observation group was higher than that of the control group, HbA1c was lower than that of the control group and body mass index was lower than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The group guidance based on intelligent communication matrix can improve the self-management level of T2DM patients and reduce their body mass index and HbA1c levels, which has clinical application value.
