Objective This study aimed to investigate the regulatory effect of electroacupuncture(EA)intervention on the protein kinase B(Akt)/mammalian target of rapamycin(mTOR)/hypoxia-inducible factor 1α(HIF-1α)signaling pathway in the hippocampal tissue of Alzheimer's disease(AD)model mice and its effect on astrocytic glycolytic function,further exploring how EA ameliorates AD-related cognitive impairment.Methods Eighteen APP/PS1 mice were randomly divided into model,EA,and sham EA groups(n=6)using the random number table method.Six wild-type C57BL/6J mice served as the control group.The EA group received EA stimulation at acupoints"Shenshu"(BL23),"Baihui"(GV20),and"Zusanli"(ST36)(administered every other day,20 min per session,for 4 weeks).The sham EA group received identical needle insertions at the same acupoints without electrical stimulation.The control and model groups were only restrained.Cognitive function was assessed using the Morris water maze and Y-maze spontaneous alternation tests.Hippocampal morphology was observed via hematoxylin and eosin staining.Hippocampal β-amyloid peptide 1-42(Aβ1-42)deposition was detected using immunohistochemistry.HIF-1α protein expression,the p-Akt/Akt,and p-mTOR/mTOR ratios were measured using Western blotting.Pyruvate kinase M2(PKM2)and lactate dehydrogenase A(LDHA)activities were quantified using enzyme-linked immunosorbent assay.Hexokinase(HK)activity and L-lactate content were determined using a colorimetric assay.Co-localization of LDHA with the astrocyte marker glial fibrillary acidic protein was quantitatively analyzed using immunofluorescence double-labeling combined with Pearson's correlation coefficient.Results Compared with the control group,the model group mice exhibited cognitive decline,as shown by prolonged escape latency(P<0.01),reduced number of platform crossings,lower time spent in the target quadrant,and decreased spontaneous alternation accuracy(P<0.01).The hippocampal neurons showed cell body swelling,deeper nuclear staining,enlarged intercellular spaces,and increased average optical density of Aβ1-42(P<0.01).The p-Akt/Akt and p-mTOR/mTOR ratios,as well as HIF-1α protein expression,were elevated(P<0.01).PKM2,LDHA,HK,and L-lactic acid levels were significantly increased(P<0.01),and the co-localization coefficient of LDHA with astrocytes was enhanced.Compared to the model group,the EA group of mice showed improved cognitive function.The hippocampal neurons had more intact structures,with a more uniform cell distribution.The average optical density of Aβ1-42 decreased(P<0.01),and the p-Akt/Akt and p-mTOR/mTOR ratios,as well as HIF-1α protein expression,decreased(P<0.01).PKM2,LDHA,HK,and L-lactic acid levels decreased(P<0.05),and the co-localization coefficient of LDHA with astrocytes significantly decreased(P<0.01).No significant improvement was observed in any of the indicators in the sham EA group compared with the EA group.Conclusion EA at"Shenshu"(BL23),"Baihui"(GV20),and"Zusanli"(ST36)ameliorates cognitive dysfunction in AD model mice.The underlying mechanism may involve suppressing the overactivation of the hippocampal Akt/mTOR/HIF-1α signaling pathway,thereby downregulating key glycolytic enzyme activities and reducing abnormal lactate accumulation.Furthermore,the astrocytic glycolytic metabolic pathway may constitute a key therapeutic target for this intervention.

Objective:To investigate whether vestibular-evoked myogenic potentials (VEMP) can be used to assess brainstem and its supplementary diagnostic value in patients with early-stage Parkinson′s disease (PD).Methods:A total of 123 patients with early-stage PD (PD group) diagnosed in the Department of Neurology of the Second Affiliated Hospital of Soochow University from January 2019 to January 2022 were consecutively enrolled, and 122 healthy controls (healthy control group) were included. Cervical VEMP (cVEMP) and ocular VEMP (oVEMP) examinations were performed on all subjects. VEMP parameters between the 2 groups were compared, and receiver operating characteristic curve was used to evaluate the auxiliary diagnostic efficacy of VEMP for early-stage PD. Correlations between VEMP parameters and motor and non-motor symptoms such as autonomic dysfunction were analyzed in the PD group using Spearman correlation analysis.Results:Bilateral latencies of cVEMP [left P1 latency (Lp13): 19.0 (16.4, 20.9) ms vs 13.1(12.0, 14.2) ms, Z=-11.18, left N1 latency (Ln23): 27.4 (24.6, 29.9) ms vs 21.2 (19.8, 23.0) ms, Z=-10.14; right P1 latency (Rp13): 18.8 (16.2, 20.9) ms vs 13.0 (11.7, 14.1) ms, Z=-10.84, right N1 latency (Rn23): 27.7 (24.3, 29.7) ms vs 21.1 (19.6, 22.9) ms, Z=-10.50] and bilateral latencies of oVEMP [left N1 latency (Ln10): 12.7 (10.7, 14.4) ms vs 10.4 (9.7, 11.4) ms, Z=-8.02, left P1 latency (Lp15): 16.5 (15.1, 18.3) ms vs 14.5 (13.4, 15.3) ms, Z=-7.96; right N1 latency (Rn10): 12.8 (11.4, 14.0) ms vs 10.5 (9.7, 11.5) ms, Z=-8.85, right P1 latency (Rp15): 16.7 (15.3, 18.3) ms vs 14.4 (13.3, 15.1) ms, Z=-9.39] of the PD group significantly prolonged compared to the healthy control group (all P<0.001). Compared to the healthy control group, the area under the curve (AUC) values of Lp13, Ln23, Rp13 and Rn23 of cVEMP in the PD group were all greater than 0.7, and the AUC values of Lp13 and Rp13 in the PD group were greater than 0.9 (all P<0.001); the AUC values of Ln10, Lp15, Rn10, and Rp15 of oVEMP in the PD group were all greater than 0.7 (all P<0.001). The Rn10-p15 corrected amplitude in PD patients was positively correlated with levodopa equivalent dose ( r=0.21, P=0.020). The Rn10 in PD patients was positively correlated with the Non-Motor Symptoms Questionnaire scores ( r=0.21, P=0.023). The Lp13-n23 corrected amplitude was negatively correlated with the Scale for Outcomes in Parkinson′s Disease-Autonomic scores ( r=-0.20, P=0.023). There was no significant correlation between VEMP parameters and Unified Parkinson′s Disease Rating Scale part Ⅲ score ( P>0.05). Conclusion:VEMP, especially cVEMP, as a non-invasive neuroelectrophysiological index, is an objective marker for brainstem damage and could be used for screening early-stage PD patients.

Objective:To explore the clinical effect of Bobath manipulation combined with traditional Chinese medicine fumigation and intradermal acupuncture on shoulder hand syndrome(SHS) after stroke.Methods:From April 2017 to August 2019, 80 patients with SHS after stroke admitted to the People's Hospital of Deqing County were selected, and they were divided into control group and observation group according to the random digital table method, with 40 cases in each group.The control group was treated by Bobath therapy, and the observation group was treated by Bobath therapy combined with acupuncture(intradermal acupuncture) and traditional Chinese medicine fumigation.After 8 weeks of treatment, the ROM scale, FMA scale, BI scale and VAS scores were used to evaluate the improvement in the mobility of the shoulder and wrist joints, motor function of the upper limbs, quality of life and pain, and the clinical efficacy of the two groups was compared.Results:Compared with before treatment, the ROM scale score of all dimensions of shoulder and wrist mobility, FMA scale score and BI scale score of all patients after treatment increased significantly, and the VAS score decreased significantly, the differences were statistically significant(all P<0.05). Compared with the control group after treatment, the improvement of the indicators mentioned above of the observation group were better[shoulder joint flexion ROM score: (154.83±25.63)points vs.(133.82±22.03)points; shoulder joint abduction ROM score: (152.36±25.68)points vs.(133.35±19.96 )points; shoulder joint external rotation ROM score: (75.87±14.69)points vs.(60.82±16.57 )points; wrist joint palm flexion ROM score: (73.94±14.37)points vs.(57.37±9.47)points; wrist joint back extension ROM score: (60.83±7.61)points vs.(42.27±6.37 )points; FMA scale score: (45.74±6.82)points vs.(34.19±4.07)points; BI scale score: (70.36±12.09)points vs.(58.70±12.53)points; VAS score: (1.05±0.49)points vs.(3.37±1.14)points, t=3.703, 3.715, 3.257, 5.576, 7.964, 3.037, 8.746, 3.153, all P<0.05]. The total effective rate of the observation group was significantly higher than that of the control group[97.5%(39/40) vs.62.5%(25/40), χ 2=15.313, P<0.05)]. Conclusion:The combination of Bobath therapy with traditional Chinese medicine fumigation and intradermal acupuncture can improve the pain degree, joint mobility disorder, upper limb motor function and quality of life of SHS patients, the efficacy is better than single Bobath therapy.The clinical effect is accurate, and it is worthy of further promotion and application.
10.Pay attention to the standardized management of sleep disorders in Parkinson's disease
Chinese Journal of Neurology 2019;52(5):361-363
Various sleep disorders are the most common group of non-motor symptoms in Parkinson's disease (PD),which can also occur during the prodromal phase of PD.All types of sleep disturbances may be encountered in PD:insomnia,excessive daytime sleepiness,rapid eye movement sleep behavior disorders,restless legs syndrome and sleep-disordered breathing.Standardized management of PD patients with sleep disturbance will be beneficial to improve the overall quality of diagnosis,treatment and prognosis.More high-quality clinical trials need to be carried out in the future.
