Objective:To explore the regional brain activities in healthy adolescent subjects after sleep deprivation (SD) using amplitude of low-frequency fluctuation (ALFF) method.Methods:Total of 16 healthy adolescent subjects (8 males,8 females;aged 13-20 years) were recruited in the community and the campus through the internet and posters.Each of the 16 healthy adolescent subject underwent the attention network test and magnetic resonance imaging (MRI) session twice:once was after rested wakefulness (RW condition),and the other was after SD condition.Amplitude of low frequency fluctuation (ALFF) method was used to assess the local brain features.The mean ALFF signal values of the different brain areas were performed to investigate their relationships with the accuracy rate,reaction time and lapse rate in the attention network test,and were analyzed with a receiver operating characteristic (ROC) curve to investigate their sensitivities and specificities to distinguish the SD condition from the RW condition.Results:Subjects showed a lower response accuracy rate [(83 ± 12) ％ vs.(97 ± 4) ％,P ＜ 0.05],a longer response time [(832 ± 134) ms vs.(715 ± 97) ms,P ＜ 0.05] and a higher lapse rate [(15 ± 11)％ vs.(2.4 ±7.3)％,P ＜0.05] under SD condition than under RW condition.They showed higher ALFF area in the right cuneus (BA 17,BA 18),and lower ALFF areas in the right lentiform nucleus,right claustrum,left dorsolateral prefrontal cortex (BA 46) and left inferior parietal cortex (BA 39) under SD condition than under RW condition.Under SD condition,the mean ALFF signal value of the right claustrum showed a significant positive correlation with the accuracy rate (r =0.69,P ＜0.05),and a negative correlation with the lapse rate (r =-0.71,P ＜0.05).The mean ALFF signal value of the dorsolateral prefrontal cortex showed a significant positive correlation with the reaction time (r =0.68,P ＜ 0.05).The values of area under the curve of the right cuneus,right lentiform nucleus,right claustrum,left dorsolateral prefrontal cortex and left inferior parietal cortice were 0.9,0.8,0.9,0.8 and 0.9,respectively.These different ALFF areas also showed high degree of sensitivities and specificities.Conclusion:Sleep deprivation leads to the dysfunction in the default mode network,anticorrelatedtask-positive network,and advanced cognitive function brain areas,and the functional compensation in the visual network.

Objective To renovate angiography in identifying portal vein anatomy during transjugular intrahepatic portosystemic shunt (TIPS) procedures,saving the time of TIPS procedures,decreasing the risk of the complications of the post-procedure.MethodsThe difference between the Wedge hepatic venography with Carbon Dioxide in 6 cases and Inferior Mesenteric artery angiography in 7 cases during TIPS procedures were compared in the identification of portal vein anatomy.The quality of images,their effects on the procedures,the complications and the recovery post-procedure were evaluated.Results Using CO2,the portal veins were opacified in all 6 cases.TIPS procedures succeeded in all cases except 1 case because of poor coagulation function.Using Inferior Mesenteric artery angiography,the portal veins were opacified in al1 7 cases.TIPS procedure succeeded in all cases except 1 case because of chronic portal occlusion.Puncture-site hematoma occurred in 1 case after TIPS procedure.ConclusionWedge hepatic venography with Carbon Dioxide is superior,safer and more convenient than Inferior Mesenteric Artery angiography in identifying portal vein anatomy during TIPS.

Objective:To investigate clinical characteristics of bullous pemphigoid (BP) developing after the treatment with dipeptidyl peptidase-Ⅳ inhibitors (DPP4i) in patients with diabetes mellitus.Methods:A total of 116 inpatients with BP complicated by diabetes mellitus were collected from the Seventh People′s Hospital of Shenyang between January 2014 and December 2020, and divided into 2 groups: DPP4i-BP group treated with DPP4i before the onset of BP, and general BP group receiving no treatment with DPP4i. General clinical data, skin lesion area, laboratory indicators, treatment regimens, and prognosis were analyzed and compared between the above 2 groups, the time interval from the administration of DPP4i to the diagnosis of BP was recorded in the DPP4i-BP group. One-way analysis of variance was used to compare measurement data among multiple groups, two-independent-sample t test was used for comparisons between two groups, and paired t-test for intra-group comparisons before and after treatment; chi-square test was used to compare enumeration data between groups. Results:There were 32 patients aged 77.17 ± 15.32 years in the DPP4i-BP group, with a male-to-female ratio being 15∶17; there were 84 patients aged 76.65 ± 19.32 years in the general BP group, with a male-to-female ratio being 43∶41. The time interval from the administration of DPP4i to the diagnosis of BP was 14.61 ± 3.93 months in the DPP4i-BP group. The time interval for vildagliptin was the shortest (5.42 ± 2.84 months) , and there was a significant difference in the time interval among vildagliptin, sitagliptin, linagliptin and saxagliptin ( F= 8.93, P < 0.001) . The proportion of patients with severe BP was significantly higher in the DPP4i-BP group (16 cases, 50%) than in the general BP group (25 cases, 29.76%; Z= 2.63, P= 0.008) . There was no significant difference in the positivity rate of anti-BP180 antibody between the two groups ( χ2= 0.03, P= 0.870) . However, the level of anti-BP180 antibody was significantly higher in the DPP4i-BP group than in the general BP group before and after treatment ( P= 0.015, < 0.001, respectively) , and the decrease in the level of anti-BP180 antibody was significantly less in the DPP4i-BP group than in the general BP group after treatment ( t= 5.11, P < 0.001) . There was no significant difference in the average effective dose of glucocorticoids required to control the disease between the two groups ( t= 1.00, P= 0.322) . However, the DPP4i-BP group showed a significant increase in the average time required to control the disease and in the proportion of patients requiring combined treatment with immunosuppressants or other drugs compared with the general BP group ( t= 6.72, 10.05, P < 0.001,= 0.002, respectively) . Within 6 months after the start of systemic treatment, the recurrence rate was significantly higher in the general BP group (17 cases, 27.86%) than in the DPP4i-BP group (2 cases, 7.69%; χ2= 4.35, P= 0.037) ; at 6 months, the average dose of glucocorticoids was also significantly higher in the general BP group than in the DPP4i-BP group ( t= 7.04, P < 0.001) . Conclusions:Among the DPP4i hypoglycemic drugs, vildagliptin was the most common drug administrated by patients before the onset of BP, with the shortest interval from the administration to the onset of BP. DPP4i-BP may be difficult to control at the early stage, but the prognosis is good.

Objective To investigate the effects of fasting serum triglycerides (TG) levels at different baseline on the risk of new-onset acute pancreatitis (AP) in in-service and retired employees of Kailuan Group.Methods A total of 125 178 in-service and retired employees of Kailuan Group who received health check-ups from 2006 to 2009 and had no AP history but had complete TG data were prospectively enrolled.According to quantile level,the baseline serum fasting TG level of study subjects were divided into ＜1.01 mmol/L group (n=42 128),1.01 to 1.64 mmol/L group (n=41 711) and ＞ 1.64 mmol/L group (n=41 339).The incidence of new-onset AP of these three groups was analyzed.The survival curve was plotted by Kaplan-Meier method.The cumulative incidence rate was calculated and tested by log-rank method.And multivariate Cox proportional hazards regression model was performed to calculate hazard ratios (HR) of baseline fasting serum TG level for AP.Results After followed up for (7.36±1.23) years,a total of 193 cases of AP occurred.The incidences of AP in ＜1.01 mmol/L group,1.01 to 1.64 mmol/L group and ＞ 1.64 mmol/L group were 1.43 events/10 000 person-years,2.37 events/10 000 person-years and 2.49 events/10 000 person-years,respectively.The cumulative incidence rates of AP in ＜1.01 mmol/L group,1.01 to 1.64 mmol/L group and ＞1.64 mmol/L group were 0.10％ (44/42 128),0.18％ (73/41 711) and 0.18％ (76/41 339),respectively,and the difference was statistically significant (x2 =9.998,P=0.007).The results of multivariate Cox proportional hazards regression model analysis indicated that the risk of AP increased in 1.01 to 1.64 mmol/L group and ＞ 1.64 mmol/L group compared with that of ＜1.01 mmol/L group,HR and 95％ confidence interval (CI) were 1.56 (1.07 to 2.29) and 1.57 (1.06 to 2.32),respectively.After excluded onset AP within one year,with a control group of ＜1.01 mmol/L group,the results of multivariate Cox proportional hazards regression model analysis indicated that the HR and 95％CI for AP of 1.01 to 1.64 mmol/L group and ＞ 1.64 mmol/L group were 1.70 (1.11 to 2.58) and 1.69 (1.10 to 2.60),respectively.Conclusion Baseline fasting serum TG levels over 1.01 mmol/L may increase the risk of AP.
