Résumé

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.

Résumé

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.

Résumé

Objective To explore the clinical,imaging,genetic features in a case of fatal familial insomnia (FFI),and review related literatures.Methods A case of middle-aged woman diagnosed as frontotemporal dementia based on the preliminary manifestation of abnormal mental behavior was reported.The clinical features,imaging characteristics,electroencephalogram and polysomnogram of the patient were analyzed,and the blood samples from the patient and some of her familial members were collected for the sequencing of prion protein gene (PRNP).Results This patient was a middle-aged woman,whose clinical manifestations were abnormal mental behavior,rapid progressive dementia and intractable insomnia,abnormal night sleep behavior and laryngeal stridor.Brain MRI indicated frontotemporal lobe atrophy.Non-sleep disturbance was observed in polysomnography.The cerebrospinal fluid was negative for 14-3-3 protein.The results of PRNP sequencing revealed that the mutation of gene D178N/129M was detected.Conclusions Detection of PRNP plays an important role in the diagnosis of FFI.Patients suspected of FFI in clinic should be detected for genetic testing.Whether the frontotemporal lobe atrophy was caused by FFI or concurrent with FFI remains to be further verified.

Résumé

Objective To evaluate the efficacy and safety of inhaled corticosteroids for preventing chronic lung disease (CLD) in preterm infants. Methods PubMed, EMBASE, CENTRAL, the ISI Web of Knowledge databases, CBM, CNKI, VIP and Wanfang Data were searched for the period up to Oct. 2016. All randomized controlled trials (RCTs) about inhaled corticosteroids for preventing CLD in preterm infants were collected. The RCTs had been screened, data were extracted and assessed. The mata-analysis was performed by RevMan 5.3 software. Result A total of 12 RCTs were included (a total of 2051 preterm neonates). Compared with control group, in 28 day old group, the incidence of CLD was not significantly different between experimental and control groups (RR=0.87, 95%CI:0.74-1.03, P=0.11) and (RR=1.19, 95%CI:0.59-2.43, P=0.63) and no significant difference among subgroups budesonide (α), beclomethasone (β), fluticasone (γ) (RR=0.89, 95%CI:0.69-1.14, P=0.35), (RR=0.86, 95%CI:0.69-1.08, P=0.19) and (RR=0.91, 95%CI:0.60-1.38, P=0.19). In 36 wk postmenstrual age group,the incidence of CLD was decreased in experimental group and in subgroups inhalation (A), Intratracheal administration (B), α, γ (RR=0.70, 95%CI: 0.61-0.80, P<0.00001), (RR=0.74, 95%CI: 0.63-0.87, P=0.0003), (RR=0.57, 95%CI: 0.43-0.76, P=0.0002), (RR=0.67, 95%CI: 0.57-0.78, P<0.00001) and (RR=0.58, 95%CI: 0.36-0.94, P=0.03); but it is not significantly different in subgroup β(RR=0.98, 95%CI: 0.69-1.39, P=0.90); There was no difference in the motality in experimental and subgroups A ,B, α, β , γ (RR=1.07, 95%CI:0.86-1.33, P=0.55), (RR=1.24, 95%CI: 0.97-1.59, P=0.09), (RR=0.67, 95%CI: 0.43-1.03, P=0.07), (RR=1.04, 95%CI: 0.81-1.33, P=0.78), (RR=1.47, 95%CI: 0.79-2.74, P=0.22) and (RR=0.91, 95%CI: 0.47-1.74, P=0.77). No clinically significant adverse effects were observed during the study. Conclusions This updated review indicated that early administration of inhaled steroids to very low birth weight preterm neonates was effective in reducing the incidence of CLD. There was no statistically significant effect of inhaled steroids on motality, and there was no significant correlation between the mode of administration and the type of drug delivery, It is recommended to observe the 36 week gestational age as the outcome index. More and larger randomised placebo-controlled trials including long-term follow up are needed to establish the efficacy and safety of inhalation corticosteroids.

Résumé

The pharmacodynamics of compound Guhuanzhixue granule(CGH- ZX)was studied.The results showed that CGHZX inhibited the contraction of rat's uterine smooth muscle and antagonized the vigorous contraction induced by oxytoxin in vitro,It exerted an anti-inflammatory effect in rats and miee with uteritis caused by various foreign bodies,This preseription also shertened the bleeding and coagulation times in mice.It is suggested that CGHZX is applicable to metrorrhagia,pain and uteritis occurring after setting of contra- ceptive ring.
