Objective To explore the associated factors for quality of life in patients with progressive supranuclear palsy (PSP). Methods A total of 218 PSP patients were included from January 2012 to December 2019. Demographic and clinical data were collected. The quality of life was evaluated by the 39⁃Item Parkinson's disease Questionnaire (PDQ⁃39). The Progressive Supranuclear Palsy Rating Scale (PSPRS) was used to assess the severity of PSP related motor and non⁃motor symptoms, while the Non⁃Motor Symptoms Scale (NMSS) was used to elevate the non⁃motor symptoms, Hamilton Depression Rating Scale⁃24 (HAMD⁃24), Hamilton Anxiety Rating Scale (HAMA), Lille Apathy Rating Scale (LARS), Frontal Assessment Battery (FAB), and Montreal Cognitive Assessment (MoCA) were used. The Pearson and partial correlation followed by the multiple linear regression were used to explore the correlates of the PDQ⁃39 score. Results Correlation analysis indicated that the PDQ⁃39 score was positively correlated with disease duration (r=0.301, P=0.000), Charlson Comorbidity Index (CCI; r=0.147, P=0.031), levodopa equivalent daily dose (LEDD; r=0.225, P=0.001), and scores for the PSPRS (r=0.551, P=0.000), NMSS (r=0.484, P=0.000), HAMD⁃24 (r=0.515, P=0.000), HAMA (r=0.439, P=0.000) and LARS (r=0.476, P=0.000), but was negatively correlated with scores of FAB (r=⁃0.325, P=0.000) and MoCA (r=⁃0.355, P=0.000). Multiple linear stepwise regression model indicated that the PDQ⁃39 score was significantly associated with female (P=0.021), longer disease duration (P=0.026), higher LEDD (P=0.008), higher PSPRS score (P=0.000), higher NMSS score (P=0.002), higher HAMD⁃24 score (P=0.004), and higher LARS score (P=0.000). Conclusions Female, longer disease duration, higher LEDD, and more severe motor and non⁃motor symptoms contribute to the reduced quality of life in patients with PSP. Our study is beneficial to the clinical management of patients with PSP.

The study aimed to investigate the impact of dietary supplementation with Chinese herbal additives on the serum immunity, cytokines, antioxidant indices, and rectal microbiota in Simmental beef cattle. Using a single-factor randomized block design, 20 healthy Simmental beef cattle with an average age of 12 months and a mean weight of (268.80 ± 4.95) kg were randomly assigned to a control group (CG group) and an experimental group (AG group), with 10 replicates per group and one beef cattle per replicate. The CG group was fed a basal diet, while the AG group received an additional 100 g/(head-day) of Chinese herbal additives on the basis of basal diet. The pre-feeding period lasted for five days, followed by a formal experimental period of 60 days. The results showed that compared to the CG group, the AG group showed an increase of 12.70% and 7.58% in the serum IgA and IL-6 concentrations (P<0.05), the serum T-SOD activity increased by 3.13% (P<0.05), the MDA content decreased by 28.87% (P<0.05), and the T-AOC increased by 1.39% (P>0.05). The Shannon, Chao1, and Ace indices of the intestinal flora of Simmental beef cattle in the AG group increased by 0.17%, 1.51%, and 0.96% compared with the CG group, respectively (P>0.05). In the AG group, the relative abundance of Bacteroidetes and Verrucomicrobia increased by 6.50% and 2.94% (P>0.05), respectively. Compared to the CG group, Firmicutes decreased by 5.94% (P>0.05). The relative abundance of unclassified Bacteroidetes was higher in the AG group (P<0.05), and the relative abundance of Phocaeicola and Alistipes increased by 8.33% and 16.45% (P>0.05), respectively. The study indicates that the addition of Chinese herbal additives can enhance the immune level and antioxidant capacity of Simmental beef cattle, increase the relative abundance of intestinal microbiota, promote the growth of beneficial gut bacteria, and improve the cattle's ability to digest fiber.

Early rice easily suffers from low temperature injury at seedling raising stage, resulting in yield reduction. Therefore, it is necessary to develop low temperature tolerant rice seedling substrate to ensure early rice production. The fermentation substrate made by ourselves was used in the present study. After melatonin and methyl jasmonate were added in the substrate, the rice was treated with low temperature for 3 days at seed germination stage and 7 days' growth stage. Then, to clarify the regulatory mechanism of these two phytohormones on the tolerance of early rice seedlings to low temperature stress, the germination status, physical and chemical properties, and gene expression of rice were explored. The results showed that both melatonin and methyl jasmonate could significantly improve the seed germination rate and germination potential of rice under low temperature. Both could improve the growth of rice, including plant height, root length, root number, dry matter weight, leaf age, and nutrient content. Under low temperature, melatonin and methyl jasmonate both reduced hydrogen peroxide and malondialdehyde content in rice by regulating the activities of antioxidant system enzymes, so as to alleviate the lipid peroxidation damage caused by low temperature stress. Melatonin and methyl jasmonate both increased the contents of proline and chlorophyll, and decreased the content of abscisic acid in rice under low temperature stress. Methyl jasmonate along increased GA3 content in rice under low temperature conditions. Melatonin and methyl jasmonate had different regulatory effects on cold tolerance genes expression in rice. Both of them significantly up-regulated the relative expression of OsCDPK7 and OsLti6b genes, and down-regulated the expression of OsWRKY45 gene in rice under low temperature conditions. In addition. The relative expression of OsFer1 gene was induced by melatonin alone, while the relative expression of OsTrx23 gene was up-regulated by methyl jasmonate alone in response to low temperature stress. The above results showed that both melatonin and methyl jasmonate could improve the low temperature stress tolerance of rice by regulating the enzyme activity of antioxidant system, osmotic substance content, chlorophyll content, plant hormone content and the expression of cold tolerance genes in rice.

Considering that I GBA i , I TMEM175 i , and I SNCA i are risk genes for both LBD and PD, it is noteworthy to investigate whether I BIN1 i and I APOE i are also associated with the risk of PD.

Similarly, a previous study identified that the I BIN1 i variant rs13403026 was associated with later AAO in I GBA i -associated PD [4], suggesting the potential role of I BIN1 i in regulating AAO in PD.
