Objective:To explore the correlation between high cholinergic pathway signaling and cognitive function in patients with Parkinson disease(PD) accompanied with sleep disorder.Methods:PD patients admitted from 2017 to 2022 were divided into PD with sleep disorder group (PD-SD group) ( n=56) and PD without sleep disorder group (PD-NSD group) ( n=41) according to the Parkinson's disease sleep scale (PDSS) score. All participants underwent magnetic resonance imaging examination.All patients were evaluated by the PDSS, Hoehn-Yahr (H-Y), Montreal cognitive assessment scale (MoCA), and cholinergic pathways hyper intensities scale (CHIPS). The difference of cognitive function between the two groups and the correlation between CHIPS and cognitive function were analyzed.Independent sample t-test, Spearman correlation analysis, and binary Logistic regression analysis were performed on the data by SPSS 26.0 statistical software. Results:(1)The MoCA score of the PD-SD group (22.00 (5.00)) was lower than that of the PD-NSD group (26.00 (5.00)) ( Z=-3.830, P<0.05). The total and all aspects scores of CHIPS in PD-SD group were higher than those in PD-NSD group(the total score of the low external capsule: 12.00(8.00), 0(8.00), the total score of the high external capsule: 12.00(2.00), 6.00(9.00), the total score of the radial crown: 8.00(0), 4.00(4.00), the total score of the centrum semiovale: 3.00(4.00), 0(2.00), the total score of the right side: 16.00(9.00), 5.00(10.00), the total score of the left side: 17.00(6.00), 7.00(9.00), the total score of CHIPS: 32.00(14.00), 14.00(20.00))( Z=-5.081, -5.873, -4.933, -3.211, -5.562, -6.232, -5.995, all P<0.05). (2)The correlation analysis between the score of CHIPS and cognitive function in the PD-SD group showed that, the total score of the low external capsule ( r=-0.286), the total score of the centrum semiovale ( r=-0.307), the total score of the right side ( r=-0.376), the total score of the left side ( r=-0.284) and the total score of CHIPS ( r=-0.349) were negatively correlated with MoCA(all P<0.05). (3)Binary Logistic regression analysis showed that white matter lesions in centrum semiovale, low inner capsule, right and left leukodystrophy were not influence factors for cognitive impairment (all P>0.05). Conclusion:PD patients with sleep disorders have lower cognitive function scores, higher CHIPS scores, and significant changes in white matter lesions compared to those without sleep disorders. In PD patients with sleep disorders, the higher the CHIPS score, the lower the cognitive function score, and the more significant the rate of cognitive impairment occurrence and development.

Objective:To explore the utility of applying low frequency transcranial magnetic stimulation (rTMS) in the acute stage of ischemic stroke in terms of improving upper limb motor function.Methods:Eighty ischemic stroke survivors in the acute stage were randomly divided into a control group and an experimental group, with 40 in each. In addition to routine rehabilitation, the experimental group was given low frequency rTMS, while the control group was provided with sham rTMS. Before and after 4-weeks of treatment, upper limb motor function was evaluated using the Fugl-Meyer rating scale (FMA), Wolf motor function tests (WMFTs), the modified Barthel index (MBI) and in terms of motor evoked potential (MEP) latency and amplitude.Results:There were no significant differences between the two groups before the treatment. Afterward, however, the average FMA, WMFT, MBI scores had improved significantly more in the experimental group, on average, as had the average MEP amplitude.Conclusion:Low frequency rTMS in the acute phase of ischemic stroke can improve upper limb motor function and ability in the activities of daily living.

Objective: To understand the prevalence of hyperuricemia in university students and examine associated factors,and to provide evidence for the prevention and treatment of hyperuricemia. Methods: Health examination data of 11 858 students for admission in October 2021 were used to compare the detection rates between groups with different characteristics. Multivariable Logistic regression was performed to identify potential factors associated with hyperuricemia. Results: A total of 3 372 cases of hyperuricemia were found, with a detection rate of 28.4%. The detection rate of male students was significantly higher than that of female students (42.4%,14.6%). The rate increased with higher BMI. Moreover, the detection rate was higher among undergraduates and those with hypertension( χ 2=1 126.2, 180.7, 138.2 ,107.9, P <0.01). Multivariable Logistic regression analysis showed that male sex, younger age, higher BMI, hypertension and higher hemoglobin level were positively associated with hyperuricemia, whereas higher glomerular filtration rate was negatively associated among the students( P <0.01). Conclusion Greater attention should be given to hyperuricemia in university students, and targeted health education should be strengthened for them, especially undergraduates, boys, overweight and obese students, and those with hypertension or high hemoglobin levels.

Objective:To investigate the differences of white matter diffusion properties between vulnerable and resistant individuals to continuous attention after sleep deprivation.Methods:According to the psychomotor vigilance test performance before and after sleep deprivation, the participants were divided into the vulnerable group( n=24) and resistant group( n=25). All participants underwent diffusion tensor imaging (DTI) scans.Tract based spatial statistics(TBSS) was used to compare fractional anisotropy(FA), mean diffusivity(MD), axial diffusivity(AD), radial diffusivity(RD) maps between the two groups.Spearman correlation analysis was conducted by SPSS 24.0 to investigate the relationships between the altered DTI metrics and PVT task performance.

(2) Compared with resistant group, MD value of vulnerable group increased in the body of corpus callosum(x, y, z=-3, -6, 26, t=7.613), right superior longitudinal fasciculus(x, y, z=-31, -19, 38, t=5.314), bilateral anterior limb of internal capsule(x, y, z=-16, 7, 8, t=6.898; x, y, z=15, 5, 7, t=6.652), splenium of corpus callosum(x, y, z=27, -53, 17, t=6.541), and AD value increased in the right superior longitudinal fasciculus(x, y, z=-33, -19, 39, t=4.892), splenium of corpus callosum(x, y, z=-22, -49, 21, t=5.450), genu of corpus callosum(x, y, z=4, 26, 0, t=4.332), as well as RD value increased in the right superior corona radiata(x, y, z=-17, 1, 33, t=7.558), body of corpus callosum(x, y, z=4, -8, 26, t=6.699), right anterior limb of internal capsule(x, y, z=-12, 7, 3, t=5.212) (TFCE corrected, P<0.05, cluster size≥50 voxel). (3) Correlational analysis revealed that the negative correlations were found between PVT task performance and the FA value in the right superior longitudinal fasciculus( r=-0.492, P<0.001), right anterior limb of internal capsule( r=-0.510, P<0.001), right posterior thalamic radiation( r=-0.502, P<0.001) and body of corpus callosum( r=-0.464, P<0.001). The positive correlations were found between PVT task performance and the MD value in the body of corpus callosum( r=0.500, P<0.001), right superior longitudinal fasciculus( r=0.499, P<0.001), splenium of corpus callosum( r=0.462, P<0.001), right anterior limb of internal capsule( r=0.471, P<0.001), and AD value in right superior longitudinal fasciculus( r=0.643, P<0.001), as well as RD value in right superior corona radiate( r=0.498, P<0.001) (Bonferroni corrected, P<0.003). Conclusion:Differences in the microstructural characteristics of white matter fiber tracts in specific brain regions may constitute the potential neuropathological basis for the phenotypes of vulnerable and resistant individuals to continuous attention after sleep deprivation.

Objective:To develop a specialized clival-cervical plate fixation (CCPF) for anterior surgery to treat craniovertebral instability, and to compare it with a posterior occipitocervical fixation (POCF) in biomechanical validation.Methods:Based on the measurement of 40 adult dry bones and 30 volunteers CT images, the clival-cervical plate was designed and manufactured. 8 cadaveric specimens (occiput-C 3) were tested in five conditions including the intact status, the intact+CCPF status, the injury status, the injury+CCPF status, and the injury+POCF status. Specimens were applied a pure moment of 1.5 N·m in flexion, extension, lateral bending, and axial rotation. Calculating and comparing the range of motion (ROM) and neutral zone (NZ) for the occiput to C 2. The effects of different fixation methods on the distribution of ROMs at the occipitocervical region were compared. Results:The injury+CCPF status constrained ROMs to 1.7° in flexion ( q=4.68, P=0.055) , 1.2° in extension ( q=0.39, P=0.9922) , 2.8° in lateral bending ( q=1.25, P=0.814) , and 4.3° in axial rotation ( q=5.08, P=0.035) , resulted in larger ROM in axial rotation but similar ROMs in other directions ( P>0.05) when compared with the injury+POCF status. There were no significant differences between the above two fixation methods in flexion-extension ( q=1.94, P=0.554) , lateral bending ( q=1.79, P=0.611) and axial rotation ( q=2.14, P=0.478) for the NZs. For the flexion, extension,lateral bendingand axial rotation direction, the proportion of the C 1, 2 ROM to the overall ROM was 28%, 25%, 34% and 56% respectively in the injury+CCPF status, and it was 59%, 53%, 42% and 71% respectively in the injury+POCF status. Conclusion:CCPF is a biomechanically effective alternative or supplemental method of POCF for the craniocervical instability.

To compare the performance of generalized additive model (GAM) and long short-term memory recurrent neural network (LSTM-RNN) on the prediction of daily admissions of respiratory diseases with comorbid diabetes. Daily data on air pollutants, meteorological factors and hospital admissions for respiratory diseases from Jan 1st, 2014 to Dec 31st, 2019 in Beijing were collected. LSTM-RNN was used to predict the daily admissions of respiratory diseases with comorbid diabetes, and the results were compared with those of GAM. The evaluation indexes were calculated by five-fold cross validation. Compared with the GAM, the prediction errors of LSTM-RNN were significantly lower [root mean squared error (RMSE): 21.21±3.30 vs. 46.13±7.60, <0.01; mean absolute error (MAE): 14.64±1.99 vs. 36.08±6.20, <0.01], and the value was significantly higher (0.79±0.06 vs. 0.57±0.12, <0.01). In gender stratification, RMSE, MAE and values of LSTM-RNN were better than those of GAM in predicting female admission (all <0.05), but there were no significant difference in predicting male admission between two models (all >0.05). In seasonal stratification, RMSE and MAE of LSTM-RNN were lower than those of GAM in predicting warm season admission (all <0.05), but there was no significant difference in value (>0.05). There were no significant difference in RMSE, MAE and between the two models in predicting cold season admission (all >0.05). In the stratification of functional areas, the RMSE, MAE and values of LSTM-RNN were better than those of GAM in predicting core area admission (all <0.05). has lower prediction errors and better fitting than the GAM, which can provide scientific basis for precise allocation of medical resources in polluted weather in advance.

Objective:To learn about the infection and gene polymorphisms of hepatitis E virus (HEV) in murine-shaped animals of plague foci in Yunnan Province.Methods:From July to August 2019, around 16 natural villages (4 in Mile City, 6 in Mangshi and 6 in Lianghe County), which were the foci of domestic plague in Yunnan Province, the murine-shaped animals were captured by the night-time method. The liver RNA was extracted, and the target gene of rat HEV was detected by one-step real-time fluorescence quantitative PCR, and the positive rate of rat HEV was calculated. The rat HEV positive samples were amplified by PCR for further clone sequencing, and the resulting sequences were compared with the HEV sequences registered in the GenBank and a phylogenetic tree was constructed by using MegAlign and MEGA 7.0.Results:A total of 491 murine-shaped animals were captured from 3 orders, 5 families, 8 genera, 15 species, and the positive rate of rat HEV was 4.89% (24/491). Among them, the positive rate of Rattus tanezumi and Niviventer fulvescens was 9.39% (23/245) and 1/3, respectively; and other species were negative. There was a statistically significant difference in the positive rate of rat HEV between different habitats ( P = 0.014), and the positive rate of rat HEV in the habitats near the dwellings was higher than that in other habitats ( P < 0.05). The sequence comparison analysis showed that the gene sequence of P018 from Lianghe County was 100.0% homologous to the MG813927.1 sequence of the first patient with rat HEV in Hongkong, and it was clustered into the same branch with the sequences of MG813927.1 and LC549185.1 from rat, was the type HEV C. G024 from Mangshi shared a low homology (20.7% - 31.5%) with other virus strains, and it was clustered into the same branch with a HEV sequence from an avian (AY535004.1). Conclusions:Rat HEV is prevalent in murine-shaped animals of plague foci of Yunnan Province, and there may be gene polymorphisms of rat HEV. In addition, the difference infection rate may be related to the habitats.
