Objective:To use the resting state functional network connectivity (FNC) method based on independent component analysis (ICA) to analyze the characteristics of FNC changes in patients with basal ganglia aphasia (BGA) after stroke, and to explore its occurrence and recovery mechanism under the intervention of acupuncture combined with language rehabilitation training.Methods:Using a prospective observational research method, 16 right-handed BGA patients who were treated at Beijing Hospital of Traditional Chinese Medicine, Capital Medical University from July 2021 to December 2022, as well as 14 healthy subjects matched in age, gender, education level, and handedness, were included. The resting state functional magnetic resonance imaging, demographic information, and Western Aphasia Examination data of healthy subjects and BGA patients before and after intervention were collected. The GIFT toolbox based on MATLAB platform was applied for ICA and resting state brain network FNC analysis. The FNC differences between BGA patients and healthy subjects were compared horizontally, and the FNC changes in BGA patients before and after intervention were compared vertically.Results:Compared with healthy subjects, post-stroke BGA patients showed decreased connectivity between the basal ganglia network, default network, and visual network before intervention, while increased connectivity between the auditory network, right frontoparietal network, and anterior cuneiform network; After the intervention of acupuncture combined with language rehabilitation training, the connectivity between the basal ganglia network, visual network, and anterior cuneiform network decreased, while the connectivity between the anterior convex network and bilateral frontoparietal network decreased, while the connectivity between the default network, auditory network, right frontoparietal network, and visual network increased. The BGA patient group showed enhanced connectivity between the basal ganglia network and the left frontoparietal network before and after intervention.Conclusions:The FNC changes between the basal ganglia network and other brain networks are key to reflecting the mechanism of BGA occurrence and language function recovery. Acupuncture combined with language rehabilitation training may improve language function by enhancing the connectivity between the basal ganglia network and the left frontoparietal network, and the redistribution of attention resources may also be one of the reasons for promoting language function recovery in BGA patients.

Objective To investigate the application value of limited liquid resuscitation combined with continuous renal replacement therapy (CRRT) in treatment of severe acute pancreatitis (SAP) companied with abdominal compartment syndrome (ACS).Methods The retrospective cohort study was adopted.The clinical data of 67 patients with SAP companied with ACS who were admitted to the Fuling Center Hospital of Chongqing from January 2005 to December 2014 were collected.Among 67 patients,33 receiving conventional liquid resuscitation between January 2005 and December 2010 were allocated into the control group and 34 receiving limited liquid resuscitation combined with CRRT between January 2011 and December 2014 were allocated into the observation group.Observation indicators included:(1) required fluid volume and time of negative fluid balance in the 2 groups;(2) changes of pathological and physiological indicators after treatment in the 2 groups;(3)outcomes and prognosis of patients in the 2 groups.Measurement data with normal distribution were represented as (x)±s and comparison between groups was analyzed using t test.Count data were analyzed using the chi-square test.Repeated measurement data were analyzed by repeated measures ANOVA.Results (1) Required fluid volume and time of negative fluid balance in the 2 groups:required fluid volumes at 6,24,48 and 72 hours after resuscitation were (2 449±339) mL,(4 820±757) mL,(9 428± 1 272) mL,(13 127± 1 565) mL in the control group and (2 360± 314) mL,(4 582±530) mL,(8 564± 970) mL,(11 470± 1 253) mL in the observation group,respectively,with a statistically significant difference in required fluid volume between the 2 groups (F=13.035,P＜0.05) and in required fluid volume at 48 and 72 hours between the 2 groups (t=3.132,4.794,P＜0.05).Time of negative fluid balance in the observation group and control group was (4.3± 1.7)days and (6.4 ±1.8)days,respectively,showing a statistically significant difference between the 2 groups (t =4.913,P＜0.05).(2) Changes of pathological and physiological indicators in the 2 groups after treatment:time factors:from 0 h to 168 h postoperatively,APACHE Ⅱ score,C-reaction protein (CRP),D-dimer,IAP,Bla and oxygenation index were changed from 20.9±4.1 to 13.9±2.6,from (167±39)mg/L to (55±17) mg/L,from (1 652±1 544) μg/L to (993±500)μg/L,from (23.4±3.4)cmH2O (1 cmH2O=0.098 kPa) to (21.4±2.9)cmH2O,from (4.6±1.6) mmol/L to (1.4±0.5)mmol/L,from (189±27) mmHg (1 mmHg =0.133 kPa) to (152±23)mmHg in the control group,and chaged from 21.5±5.1 to 11.0±2.8,from (168±36)mg/L to (44±19)mg/L,from (1 634±1 525) μg/L to (578±350) μg/L,from (23.2±2.5)cmH2O to (17.4±2.6)cmH2O,from (4.5±1.6)mmol/L to (0.8±0.3)mmol/L,from (188±26)mmHg to (196±25)mmHg in the observation group,respectively,showing gradual decreasing with time and statistically significant differences between the 2 groups (F =186.415,581.118,34.618,212.416,262.272,207.645,P＜0.05).Treatment factors:there were no significant differences in changing trends of APACHE Ⅱ score,D-dimer and Bla between the 2 groups (F=3.499,2.350,3.516,P＞0.05),and there were significant differences in changing trends of CRP,IAP and oxygenation index between the 2 groups (F=4.009,15.276,14.959,P＜0.05).Interaction effect between time factors and treatment factors:there were obviously interaction effects between time factors and treatment factors in APACHE Ⅱ score,CRP,IAP and oxygenation index (F=4.890,4.912,23.874,28.615,P＜0.05) and no interaction effects between time factors and treatment factors in D-dimer and Bla (F=2.803,1.920,P＞0.05).(3) Outcomes and prognosis of patients in the 2 groups:numbers of patients with surgery,local complications and infection and duration of hospital stay were 11,16,14,(46±17)days in the control group and 4,6,6,(36±14) days in the observation group,respectively,with statistically significant differences between the 2 groups (x2=4.484,7.221,4.910,t =2.433,P＜0.05).Mortality and hospital expenses were 24.2％ (8/33),(33± 18) x 104 yuan in the control group and 8.8％ (3/34),(27± 14)× 104 yuan in the observation group,respectively,with no statistically significant difference between the 2 groups (x2 =2.901,t =1.283,P＞ 0.05).Conclusion Limited liquid resuscitation combined with CRRT can effectively control IAP of patients with SAP companied with ACS and improve oxygenation index,meanwhile,it can also reduce number of patients with surgery,infection and local complications and duration of hospital stay.
