Objective To explore the cognitive status of amyotrophic lateral sclerosis (ALS) patients, and to explore the involved cognitive domains, subtypes and risk factors of mild cognitive impairment in ALS ( ALS-MCI).Methods Twenty-nine cases of ALS and 58 healthy volunteers were included.The severity of the bulbar and spinal functions of the patients was evaluated by the Improved Norris Scale.According to the Diagnostic and Statistical Manual of Mental Disorders 4th Edition-Revised( DSM-Ⅳ-R) criteria of dementia, ALS cases were classified as demented and non-demented.For non-demented ALS cases, the common cognitive batteries evaluating mental state, verbal memory, executive, attentional and visuospatial abilities were performed.Hamilton Anxiety Scale ( HAMA) and Hamilton Depression Scale (HAMD) were evaluated too.They were further classified into ALS-cognitively normal (ALS-CogNL) and ALS-MCI groups according to Petersen criteria of MCI.Risk factors possibly correlated with ALS-MCI were analyzed by comparing the differences in age, age of onset, duration of the disease, sites of onset, symptoms of bulbar and limb function between ALS-CogNL and ALS-MCI groups.Results Among 29 ALS cases, 14 (48.3% ) cases with cognitively normal( ALS-CogNL), 15 cases (51.7% ) with ALS-MCI,and none with dementia were identified.Among 15 ALS-MCI cases, 12 cases with executive dysfunction, 8 cases with memory deficits,9 cases with attention impairment and none with visuospatial impairment were found.ALSMCI cases could be further classified into three subtypes; 1 case with amnestic MCI (aMCI) ,6 cases with single domain non-memory MCI ( sdMCI), and 8 cases with multiple domains slightly impaired MCI (mdMCI).Between ALS-MCI and ALS-CogNL groups, there were significant differences (t = -2.435,- 2.576, both P ＜ 0.05) in education ((8.7 ± 2.8) years vs (11.3 ± 3.0) years) and Improved Norrisscale (bulbar score: (28.4 ± 7.7) scores vs ( 34.0 ± 3.4) scores) , however, no significant differences in sex, age, age of onset, duration,site of onset,HAMA or HAMD scores,and Improved Norris scale( spinal score) were found.Conclusions Cognitive deficits commonly exist in ALS patients.For the involved domains, executive dysfunction is the most common, deficits of attention and memory are also common, and deficit in visuospatial function is not found.The most common subtype of ALS-MCI is mdMCI.Severe bulbar symptoms and lower education may be the risk factors of ALS-MCI.

Objective:To explore the application of OTSU-based self-attenuation correction PET (sacPET) reconstruction technology in 18F-florbetapir (AV45) imaging. Methods:From November 2018 to December 2019, 7 confirmed Alzheimer′s disease (AD) patients (4 males, 3 females, age (69.6±4.5)years) and 3 healthy controls (HC; 1 male, 2 females, age (68.0±4.6) years) were recruited prospectively for 18F-AV45 PET imaging in the First Affiliated Hospital of Sun Yat-Sen University. Original data collected by PET acquisition was processed with sacPET reconstruction and then compared with standard PET images by visual analysis and semi-quantitative analysis. Fisher exact test, Kappa test and Pearson correlation analysis were used to analyze data. Results:In HC group and AD group, the radioactive distribution showed by sacPET images and that by standard PET images were similar, and the contrast of gray-white matter in sacPET images was weaker than that in standard PET images. Moreover, the positive uptake area of the cortex in the AD group was smaller than that in standard PET images. Visual analysis showed 19 positive regions in sacPET images and 22 in standard PET images, with no statistical difference of positive rates of the sub-regions in the cortex between the two PET images (all P>0.05), and the overall consistency of 88.00% (44/50; Kappa=0.75 (95% CI: 0.57-0.94), P<0.05). Semi-quantitative analysis showed that the standardized uptake value ratio (SUVR) of frontal lobe and cingulate gyrus measured by sacPET was lower than that measured by standard PET (0.93±0.06 vs 0.96±0.06 and 0.99±0.04 vs 1.01±0.04; t values: 5.30 and 5.10, both P<0.01), while SUVR of parietal lobe, temporal lobe and occipital lobe measured by sacPET was higher than that measured by standard PET (0.78±0.08 vs 0.68±0.07, 0.97±0.07 vs 0.91±0.08 and 0.94±0.11 vs 0.71±0.12; t values: 6.27, 7.36 and 16.90, all P<0.01). The overall SUVR of sacPET images was significantly correlated with the standard PET images ( r=0.75, P<0.001). Conclusion:For 18F-AV45 imaging, sacPET reconstruction technology can obtain reliable and effective PET images without CT data, but its accuracy and precision still need to be improved.

[Objective]To study the academic characteristics of the diagnosis and treatment of measles in FENG's Secret Book of Medicine,so as to provide schemes for the diagnosis and treatment of measles.[Methods]Taking the section of measles in FENG's Secret Book of Medicine as the main object of the study,the article systematically studied the characteristics of FENG's diagnosis and treatment of measles by combining the relevant contents in Inner Canon of Huangdi,Yi Guan and some other writings.[Results]FENG Zhaozhang was one of the physicians who systematically studied measles earliest in the history of Chinese medicine.In terms of diagnosis,he judged the severity of the disease by color,shape,location of the erythra and general condition of the patient,and differentiated measles from febrile diseases,smallpox and other diseases.In terms of treatment,he agreed with the predecessors on treating measles by cooling and diffusing,and he specialized in dissipating excessive stagnation of fire and eliminating fire by diaphoresis and purgation respectively.However,he clearly pointed out that the pathogenesis of measles was not only fire in lung and stomach,but also deficiency in spleen,stomach and Mingmen,and treating deficiency syndromes should always be based on strengthening the vitality,which had corrected the abuse of cooling and diffusing medicine in the treatment of measles through the ages.In addition,FENG's experience of nursing and treating pregnancy combined with measles was also of significance.[Conclusion]FENG Zhaozhang was well-experienced in the diagnosis and treatment of measles,and established complete theories,methods and prescriptions,which provided theories and methods for the diagnosis and treatment of measles,and was of significant value.

Accurate prediction of the translation initiation site (TIS) is an important issue for prokaryotic genome annotation. However, it is still a challenge for the existing methods to predict the TIS in the genomes over a wide variety of GC content. Besides, the existing methods have not yet undergone a comprehensive evaluation, leaving prediction reliability as a largely open problem. A new algorithm MED-StartPlus, a tool that predicts TIS in prokaryotic genomes with a wide variety of GC content was presented. It makes several efforts to model the nucleotide composition bias, the regulatory motifs upstream of the TIS, the sequence patterns around the TIS, and the operon structure. Tests on hundreds of reliable data sets, with TISs confirmed by experiments or having annotated functions, show that the new method achieves a totally high accuracy of TIS prediction. Compared with existing TIS predictors, the method reports a totally higher performance, especially for genomes that are GC-rich or have complex initiation mechanisms. The potential application of the method to improve the TIS annotation deposited in the public database was also proposed.

Objective To investigate the protective effect of protocatechuic acid(PCA)on the PC12 cell model of Alzheimer’s disease(AD)and to explore its mechanism . Methods Amyloid beta peptide 1-42(Aβ1-42)fiber polymers were identified by immunofluorescence. After PC12 cells were stimulated with the Aβ1-42 fiber polymers, the cellular morphology was observed at different time points of hour 0, 3, 6, 9, 12, 24 , and the cellular viability was tested by methyl thiazolyl tetrazolium(MTT)assay to monitor the modeling condition. The effect of PCA on PC12 cells was detected after PC12 cells were pretreated with the different contentions of PCA. Autophagy-related marker Beclin1 protein level was detected by Western blotting method to investigate the protective mechanism of PCA. Results Aggregated white Aβ1-42 mass was stable at hour 12 and 24, and showed no significant difference between the two time points, the cell damage rate being 40%. Therefore, we defined culturing time being 12 and 24 hours as the modeling condition of AD model. The cell viability was increased with 200-800 μmol/L of PCA after culturing for 24 hours(P<0.01) , and the Western blotting results showed that the Beclin1 protein expression was up-regulated by PCA. Conclusion PCA prevents PC12 cells from Aβ1-42-induced toxicity, the mechanism being related with the increase of cellular autophagy.
