Objective Fasting hypometabolism regulation technology has broad application potential in long-term space flight and survival in extreme extraterrestrial environments.In-depth research on the substrate conversion of energy metabolism and the formation of new steady states under fasting hypometabolism will provide theoretical basis and experimental data support for formulating effective prolonged fasting application mode.Methods 30 SD rats were randomly divided into control group and fasting group(fasting for 1,2,3,and 5 days).Blood biochemical examination,qRT-PCR,and western blotting were performed to analyze the body weight,blood biochemistry,and expression changes of genes and proteins related to glucose and lipid metabolism during different fasting periods.Results Prolonged fasting significantly reduced the body weight,blood glucose,and triglyceride levels of rats;increased the blood ketone level,and replaced glucose as the main energy substance in the body.There are temporal and tissue-specific changes as a whole.Hepatic and renal gluconeogenesis play major roles respectively during different fasting periods.As the fasting time prolongs,the level of hepatic gluconeogenesis gradually decreases,the content of FFA in the blood increases,the expression level of genes related to fat synthesis decreases,fatty acid oxidation is enhanced,and the expression level of the key gene HMGCS2 for ketone body generation increases.Conclusion During prolonged fasting,there is a significant conversion of glucose-ketone energy supply substrates,and a new steady state of energy metabolism mainly supplied by ketone bodies is formed within 2-5 days of fasting.The body maintains a low metabolic state by regulating changes in key genes in pathways such as glucose and lipid metabolism.

Objective:This study aimed to evaluate the therapeutic effect of intratympanic injection of ganglioside in patients with refractory sudden deafness. Methods:A total of 120 patients with sudden deafness, aged 18-65 years, whose onset was within 11-42 days, failed to respond to conventional treatment, and had an average hearing threshold（500-4 000 Hz）>60 dB were selected. They were prospectively and randomly divided into a control group of 61 cases and an experimental group of 59 cases. The control group was treated according to the recommended protocol of the Chinese Medical Association（postauricular injection of methylprednisolone）, while the experimental group was treated with intratympanic injection of monosialotetrahexosylganglioside sodium+postauricular injection of methylprednisolone. Both groups were simultaneously administered oral ginkgo biloba extract and citicoline tablets. Hearing was re-examined two weeks after the completion of treatment, and the therapeutic effects of the two different treatment methods were compared and analyzed. Results:The effective rate was 29.51% in the control group and 54.24% in the experimental group（P<0.01）. The average hearing threshold improved by 11.57 dB HL in the control group and 22.50 dB HL in the experimental group（P<0.05）. Conclusion:The combination of postauricular injection of methylprednisolone and intratympanic injection of ganglioside is more effective than postauricular injection of methylprednisolone alone in the treatment of refractory sudden deafness. The earlier the treatment, the better the therapeutic effect.

Objective:To explore the effect of occupational aluminum (Al) exposure on workers' overall cognitive level and speech function.Methods:In July 2019, by using cluster sampling method, the group of 232 exposed to Al from an Al plant in Shanxi Province were selected as the exposed group, and the group of 228 not exposed to Al were selected as the control group. The blood Al concentration was determined by inductively coupled plasma mass spectrometry (ICP-MAS) . The exposed group was divided into high exposure group and low exposure group according to the median ( M) concentration of Al in serum. The general cognitive function and speech function were evaluated with the Montreal Cognitive Assessment Scale (MoCA) , and the differences in the general cognitive function and speech function between the groups were compared, and non-conditional logistic regression was used to analyze the possible influencing factors of mild cognitive impairment (MCI) . Results:There were significant differences in age, working age, education and drinking status between Al exposed group and control group ( P<0.05) . The total MoCA score, animal naming tese (ANT) score and category fluency repetition (CFT) score in Al exposure group were lower than control group and the differences were statistically significant ( P<0.05) . The full rate of ANT was lower than that of CFT in Al exposure group ( P<0.05) . The total MoCA score, ANT score and CFT score in the high exposure group were significantly lower than those in the control group ( P<0.05) . The score of MoCA, ANT and CFT in high exposure group were lower than those in low exposure group between the level of serum aluminum>60 μg/L group and ≤60 μg/L group ( P<0.05) . Logistic regression analysis showed that working age, serun Al concentration, ANT score, CFT score and SR score were the possible influencing factors of MCI in occupational Al exposure workers ( P<0.05) . Conclusion:Occupational Al exposure can lead to impaired speech function of workers, the higher the ANT score, CFT score and SR score, the lower working age and serum Al concentration, the lower risk of MCI.
