Objective Curculiginis extract has good scavenging effects on oxygen free radicals, and there is no curculiginis extract for AD research at home.The aim of this study was to explore the influence of Curculigoside on the cognitive learning and memory functions of senile dementia model rats induced by D-galactose combined with β-protein amyloid β25-35 (Aa25 35) and the expression level of hippocampus B-cell lymphoma-2 (Bcl-2), Bax, estrogen receptor (ER) protein and mRNA.Methods Forty SD rats weredivided into the control group (equal saline was intraperitoneal injected for six weeks consecutively, and equal saline was injected to the bilateral hippocampus in the seventh week), the model group (galactose was intraperitoneal injected for six weeks consecutively, and 4 mmol/L Aβ25-35 was injected to the bilateral hippocampus in the seventh week), the low dosage group and the high dosage group randomly (the stomach irrigation of low dosage 24mg/kg or the high dosage 72mg/kg curculigoside was applied every day, for 8 weeks), 10 rats in each group.After the treatment , the Morris water maze was conducted to test the space learning and memory functions of rats;the flow cytometry method was conducted to analyze the neuronal apoptosis conditions;the western blot was conducted to detect Bcl-2, Bax and ER protein level;the Realtime PCR was conducted to detect Bcl-2, Bax and ER mRNA level.Results Morris water maze test results: Compared with the model group, the escape latency (EL) of the rats of the model group, the low dosage group and the high dosage group on the 2nd, the 3rd, the 4th and the 5th day significantly extends (P<0.01), and the high dosage group significantly shortens (P<0.05) than the low dosage group.Space exploration test results: Compared with the proportion of the distance swum within the quadrant by the rats in the model group in the total distance [(30.14±5.10)%], that of the low dosage group, the high dosage group and the control group [(41.98±4.78)%, (46.17± 9.31)% and (50.13±6.81)%] significantly increases (P<0.01);in addition, the high dosage group is higher than the low dosage group (P<0.05).Compared with the apoptosis rate of rates in the model group[(7.11±1.78)%], that of the high dosage group, the low dosage group and the control group[(5.53±1.45)%], (4.11±1.03)% and (3.08±1.33)% significantly decreases (P<0.05).Compared with the control group, the Bcl-2 and Bax protein expression of the model group significantly increases, and the cell Bcl-1 and Bax of cells significantly decreases (P<0.05).Compared with the model group, the Bcl-2 and ER protein expression as well as the Bcl-2/Bax of the high dosage group and the low dosage group significantly increase, and the Bax protein expression significantly decreases (P<0.05).Compared with the mRNA expression (1.00 and 1.00) of Bcl-2 and ER in the control group, the mRNA expression (1.31 and 1.98) of the Bcl-2 and Bax in the model group significantly increases (P<0.05);compared with the mRNA expression (1.13 and 1.08) of Bcl-2 and ER in the model group, the Bcl-2 (1.95 and 2.01) and mRNA expression (1.81 and 1.96) of ER of the high dosage group and the low dosage group significantly increase (P<0.01).Conclusion Curculigoside plays an improving role in space learning and memory functions of senile dementia model rats, with the mechanism may be related to the protection to the hippocampus neurons by restraining Bax expression and neuronal apoptosis through the up-regulation of hippocampus ER and Bcl-2 expressions.

ObjectiveTo observe the effect of moxibustion with medicine cake on mRNA expression of matrix metalloproteinases-2,9 (MMP-2，MMP-9)in artherosclerosis (AS) plaques of rabbits, and to explore the effect of moxibustion with medicine cake to the stability of artherosclerosis plaques of rabbits.MethodsAS rabbit models were established by feeding high-fat diet. 75 New Zealand big-eared rabbits were divided into 5 groups, blank group (blank control group), model group (AS model group), direct moxibustion group (AS model + moxa cone direct moxibustion), moxibustion on medicine cake group (AS model + moxibustion on medicine cake), western medicine group (AS model + atorvastatin), 15 rabbits in each group. Then the mRNA expression of MMP-2, MMP-9 was detected in the atherosclerotic plaques of rabbits with in situ hybridization.ResultsThe expressions of MMP-2, MMP-9 in the atherosclerotic plaques of rabbits were all be controlled in direct moxibustion group, moxibustion on medicine cake group, western medicine group (P<0.01 or P<0.05). The expressions of MMP-2 and MMP-9 in the moxibustion on medicine cake group and western medicine group were obviously lower than those of the direct moxibustion group.ConclusionThe expression of MMP-2, MMP-9 in the atherosclerotic plaques of rabbits can all be controlled in direct moxibustion group, moxibustion on medicine cake group, and western medicine group; as well as the plaques can all be made stable. The efficacy in the moxibustion on medicine cake group and western medicine group is superior to that of the direct moxibustion group.

Objective:To investigate the clinical efficacy of different grade transoral atlantoaxial release for the treatment of irreducible atlantoaxial dislocation.Methods:From January 2010 to December 2019, 297 patients with irreducible atlantoaxial dislocation treated by different grade releases were retrospectively analyzed, including 132 males and 165 females, aged 42.3±12.14 years (range, 10-63 years). All cases were treated by different grade releases, Grade I (196, 66.0%), Grade II (54, 18.2%), Grade III (28, 9.4%) and Grade IV (19, 6.4%). The American Spinal Injury Association (ASIA) grade and Japanese Orthopedic Association (JOA) score were recorded as the clinical evaluation index. The clivus-canal angle (CCA) and cervico-medullary angle (CMA) were measured to evaluate the reduction. The surgery time, blood loss, duration of bony fusion and complications were also analyzed.Results:The follow-up time was 14.8±10.2 months (range, 9-36 months). The surgery time of Grade I-IV were 2.02±0.35 min, 3.00±0.36 min, 4.07±0.96 min and 5.24±0.83 min, respectively ( F=385.43, P<0.001), blood loss was 84.08±27.21 ml, 153.61±31.36 ml, 268.93±48.94 ml and 444.21±109.51 ml, respectively ( F=582.39, P<0.001).

To investigate the expression and significance of Sox5 in serum and helper T cell 17（Th17）of patients with multiple sclerosis （MS）. Methods 20 acute exacerbation MS patients were collected as MS group and 20 healthy volunteers as health control group. The expression of Sox5 in serum was detected by ELISA，the peripheral blood CD4+T cells were isolated by flow cytometry，the Th17 cells were cultured in vitro and stimulated by IL-6（25 ng/ml）for 7 days，the Sox5 and IL-17A levels in medium were detected by ELISA，the Th17 cells were detected and isolated by flow cytometry，and the Sox5 and RORγt mRNA expressions of Th17 were detected by RT-PCR. Results The level of Sox5 in serum of MS patients was higher than that of healthy controls，the difference was significant （P<0.05）.The level of Sox5，IL-17A and Th17 cells in the CD4+T cell culture medium of the healthy control group did not increase （P>0.05），but the level of Sox5，IL-17A and Th17 cells in the MS patients significantly increased （P<0.05）；the level of Sox5 and RORγt in the CD4+T cell culture medium of the healthy control group did not increase （P<0.05）. The expression of Sox5 and RORγt mRNA in Th17 cells increased significantly in MS patients （P<0.05）. Conclusion Sox5 plays an important role in the pathogenesis of MS patients and is related to the differentiation of RORγt and Th17 cells.

Objective To discuss the correlation between gastrointestinal symptoms concomitant with chronic migraine and sleep disorders,anxiety and depression.Methods Self-rating Anxiety Scale (SAS),Self-rating Depression Scale (SDS),Pittsburgh Sleep Quality Index (PSQI) and Gastrointestinal Symptom Rating Scale (GSRS) were adopted to conduct comparative analysis on gastrointestinal symptoms,anxiety,depression,sleep disorders,and related risk factors in 151 chronic migraine patients who conformed to International Headache Society International Classification of Headache Diseases-Ⅱ diagnostic code and 151 healthy controls in the Third Affiliated Hospital of Qiqihar Medical University from January 2015 to December 2017.Results PSQI scores (8.46±2.54 vs 4.53±1.95,t=2.913,P＜0.05),SAS scores (53.24± 11.66 vs 39.58±8.63,t=3.112,P＜0.05),SDS scores (51.09±8.80 vs 36.11±5.74,t=3.520,P＜0.05),and GSRS scores (4.53 (3.74,5.32) vs 1.29 (0.73,1.31),Z=30.804,P＜0.05) were all higher in migraine patients than that in healthy controls,and the differences were all statistically significant.In chronic migraine patients,139 (92.05％) had one gastrointestinal symptom at least,and the overall incidence of each gastrointestinal symptom was abdominal distension (60 cases,39.74％),exhaust increase (51 cases,33.77％),and endless defecation (43 cases,28.48％),etc.,in turn.Multiple regression analysis showed that headache degree,frequency,PSQI scores,SAS scores,and SDS scores were the main risk factors of gastrointestinal symptoms concomitant with chronic migraine.GSRS scores of chronic migraine patients presented positive correlation with PSQI scores (r=0.65,P=0.000),SAS scores (r=0.42,P=0.000),and SDS scores (r=0.48,P=0.000),respectively.Conclusion Chronic migraine patients are easy to be accompanied with gastrointestinal symptoms,and headache degree and frequency,sleep disorders,depression and anxiety are the main risk factors of concomitant gastrointestinal symptoms.

Objective:Migraine and tremor share some genetic mutation sites,and clinical studies have also confirmed their correlation.This study aims to explore the clinical and electrophysiological characteristics of migraine patients with concomitant tremor,and to analyze the relevant influential factors of tremor occurrence. Methods:We retrospectively analyzed the clinical data of 217 migraine patients who visited the Third Affiliated Hospital of Qiqihar Medical University from June 2022 to October 2023.The Clinical Rating Scale for Tremor(CRST),Numerical Rating Scale(NRS),Generalized Anxiety Disorder-7(GAD-7),and Patient Health Questionnaire-9(PHQ-9)were respectively used to assess the tremor symptoms,degree of headache,anxiety,and depression of patients.All patients underwent routine head MR scanning and electromyography examination,and were divided into a migraine with tremor group and a migraine without tremor group based on the electromyogram examination. Results:The migraine with tremor group and the migraine without tremor group were included 52 patients(23.96%)and 165 patients(76.04%),respectively.Compared with the migraine without tremor group,the migraine with tremor group had a longer course and duration of headache,higher frequency of headache attacks,higher NRS score,GAD-7 score,and PHQ-9 score,and fewer weekly physical exercises.The differences were statistically significant(all P<0.05).There were no statistically significant differences in the presence or absence of prodromal headache and white matter hyperintensities(WMHs)between the 2 groups(both P>0.05).The evaluation results of the CRST showed that out of 217 migraine patients,39 patients(17.97%)were accompanied by tremors.The electromyographic results showed that all 52 migraine patients with tremors had upper limb tremors,including 28 migraine patients with postural tremors and 24 migraine patients with static tremors.Compared with the migraine patients with static tremors,the migraine patients with postural tremors had lower average frequency,peak frequency,and headache onset frequency(all P<0.05).Multiple linear regression analysis showed that frequency of physical exercise,duration of illness,frequency of headache attacks,NRS score,GAD-7 score,and PHQ-9 score were risk factors for migraine patients with concomitant tremors(all P<0.05). Conclusion:Patients with migraine mainly experience upper limb postural tremors.Reduced physical exercise,long course of disease,long duration of headache,frequent headache attacks,severe headache,anxiety,and depression are risk factors for migraine patients with concomitant tremors.
