ABSTRACT
Objective:To investigate the correlations of melanin concentration hormone (MCH) in cerebrospinal fluid (CSF) and serum with sleep disorder, memory dysfunction and prognoses in patients with cerebral ischemic stroke (CIS).Methods:One hundred elderly CIS patients, admitted to Department of Neurology, He'nan Provincial People's Hospital from June 2021 to January 2022 were enrolled as CIS group, and 50 subjects collected from Physical Examination of the same hospital during the same period were enrolled as control group. MCH levels in the CSF and serum were detected by ELISA. Sleep quality was assessed by polysomnography and Pittsburgh Sleep Quality Index (PSQI). Memory function was assessed by Rivermead Behavioral Memory Test 2 nd Edition (BMT-II). Prognoses were assessed by modified Rankin Scale (mRS) 3 months after discharge. The clinical data and MCH levels of the two groups were compared; the differences in MCH levels among CIS patients with different degrees of sleep disorder, and different memory functions and prognoses were compared. Correlations of MCH level and sleep parameters with RBMT-II scores in these CIS patients were analyzed. Results:Compared with that in the control group, the proportion of patients with hypertension in CIS group was significantly higher ( P<0.05). Compared with the control group ([42.39±16.11] pg/mL), the serum MCH level in CIS group ([36.89±15.19] pg/mL) was statistically lower ( P<0.05). In CIS patients, patients with mild or severe sleep disorder had significantly decreased CSF MCH level compared with patients without sleep disorder ( P<0.05), patients with severe sleep disorder had significantly decreased CSF MCH level compared with patients with mild sleep disorder ( P<0.05); patients with severe sleep disorder had significantly decreased serum MCH level compared with patients without sleep disorder ( P<0.05); CSF MCH level was negatively correlated with PSQI scores, sleep latency and wake frequency ( P<0.05), and positively correlated with percentage of rapid eye movement ( P<0.05); serum MCH level in CIS patients was negatively correlated with PSQI scores and wake frequency ( P<0.05). In CIS patients, the CSF and serum MCH levels in patients with memory dysfunction was significantly lower compared with those with normal memory function ( P<0.05); a positive correlation was noted between RBMT-II scores and CSF MCH level ( P<0.05). In CIS patients, patients with poor prognosis had statistically lower CSF and serum MCH levels compared with those with good prognosis ( P<0.05). Conclusion:The serum MCH level in CIS patients is significantly decreased, which is closely related to the occurrence of sleep disorder and memory dysfunction after stroke; and they further affects the prognoses.

Objective To investigate the characteristics of sleep structures in patients with multiple dreams through the retrospective analysis of polysomnography in patients with multiple dreams,and to provide a theoretical basis for the treatment of multiple dreams.Methods Twenty-two cases with multiple dreams in Department of Neurology,the People's Hospital of Zhengzhou University from July 2015 to Ferbuary 2018 were included in multi-dream group and 12 healthy people in control group.The sleep parameters related to polysomnography during the visit were collected and recorded,and the differences between the two groups were compared.Resluts There was no statistically significant difference in apneahypopnea index,sleep latency,rapid eye movement (REM) sleep latency,slow-wave sleep ratio,and REM-arousal index between the two groups.Compared with the control group,sleep efficiency (73.46% ± 12.41% vs 90.43% ± 4.42%,t=-4.555,P=0.000),REM period ratio (16.28% ± 5.59% vs 21.59% ± 2.70%,t =-3.727,P =0.001) decreased in the multi-dream group;whereas ratio of light sleep (66.49% ±9.97% vs 59.85% ±3.01%,t =2.966,P =0.006),awakening numbers (13.4 ±6.98 vs 6.08 ± 3.34,t =3.411,P =0.002),arousal index (20.11 ± 10.69 vs 11.82 ± 8.09,t =2.338,P =0.026),non-REM arousal index (20.22 ± 10.53 vs 12.08 ± 8.69,t =2.283,P =0.029) increased.Conclusion The sleep efficiency of patients with multiple dreams is reduced,and their perceived dreams may originate from light sleep periods.
ABSTRACT
Objective To investigate the abnormal functional connectivity (FC) between the cores (including sublaterodorsal nucleus (SLD) and ventrolateral periaqueductal gray matter (vlPAG)) and the whole brain in rapid eye movement sleep behavior disorder (RBD) by resting state functional magnetic resonance imaging (rfMRI).Methods A total of 41 subjects recruited in the Department of Neurology,the People's Hospital of Zhengzhou University were enrolled in this study according to international diagnosis criteria,including 20 with idiopathic RBD (iRBD group) and 21 age,sex-matched normal controls (control group).All subjects were examined by Hoehn-Yahr Staging,cognitive tests and rfMRI.Resluts HoehnYahr staging score was 0(0,0) in the iRBD group,which showed no significant difference from that in the control group (0 (0,0),Z =-1.820,P =0.069).The scores of Rey Auditory Verbal Learning Test (AVLT) N1,AVLT N2,Symbol Digital Modalities Test,Rey-Osterrieth Complex Figure Test-Copy were 3.80 ± 1.67,5.10 ± 1.77,33.00(31.25,34.00) and 22.00(20.25,26.00) respectively in the iRBD group,which were significantly lower than that in the control group (4.95 ± 1.28,t =2.482,P =0.017;6.43±1.16,t =2.848,P=0.007;33.00(29.50,35.50),Z=-3.792,P=0.000;35.00(33.00,36.00),Z =-2.351,P =0.019) respectively.The scores of Trail Making Test 1 (86.5 (70.0,100.0))and Trail Making Test 2 (197.0(180.5,211.5)) in the iRBD group were significantly higher than that in the control group (66.0(49.0,91.5),112.0(99.5,173.0) respectively,Z=-2.373,P=0.018;Z =-3.105,P =0.002).Compared with the control group,the FC analysis showed reduced connections from the right SLD to the bilateral cingnlate gyrus (t =-4.173) and bilateral frontal gyrus (t =-2.965(left),-3.662(right)),from the vlPAG to the left precentral-postcentral gyrus(t =3.930),and from the vlPAG to the right frontal gyrus (t =4.141) in the iRBD.There was no statistically significant difference from the left SLD to the whole brain.Conclusion There were abnormal FCs from the SLD and vlPAG to cognitive and motor areas in RBD patients,perhaps leading to clinical RBD symptoms such as cognitive deterioration and movement disorder.
ABSTRACT
Angelica dahurica is diaphoretic, commonly used in the treatment of cold, wet, and itchy rubella nasosinusitis. Studies have shown that the effective components of Angelica dahurica can be used in the treatment of malignant tumors. This paper summarizes the related literature home and abroad recently, and regards the effective components of Angelica dahurica as a major role in treatment of tumor by inhibiting tumor cell proliferation, promoting apoptosis, inhibiting tumor metastasis, inhibiting platelet aggregation, enhancing immunity, and anti-tumor drug resistance. Meanwhile, the paper finds the shortcomings of the present researches, and hopes to provide reference for the future experiment and clinical research.
ABSTRACT
Objective To investigate the abnormal functional connectivity (FC) between the substantia nigra (SN) and the brain motor area in rapid eye movement sleep behavior disorder (RBD) by Unified Parkinson′s Disease Rating Scale (UPDRS), Hoehn-Yahr Scale and resting state functional magnetic resonance imaging (rfMRI).Methods A total of 34 subjects (14 with RBD (RBD group), 12 with Parkinson′s disease (PD group), and 8 age, sex-matched normal controls (control group)) recruited in the Department of Neurology, Henan Provincial People′s Hospital from 2014 to 2015 were enrolled in this study according to international diagnosis criteria.All subjects were examined by UPDRS, Hoehn-Yahr Scale and rfMRI.Results UPDRS scores and Hoehn-Yahr staging were 0.00 (0.00, 3.75) and 0.00 (0.00, 0.50) respectively in the RBD group, which were significantly different from that in the PD group (30.5 (18.75, 33.00) and 1.75 (1.50, 2.50), respectively;Z=-3.782, P0.05 and Z=1.10, P>0.05).The FC analysis showed alterations from the right SN to bilateral cerebellum respectively among the three groups (Fright cerebellum=12.975, Fleft cerebellum=6.144;P0.05).Conclusions There was abnormal FC from the SN to motor areas in RBD patients, and partial alterations were similar as PD patients.rfMRI provided an evidence that RBD might be presymptom of PD.
