Aim To explore the differences in sedative and hypnotic effects of Semen Ziziphi Spinosae(SZS)before and after processing based on network pharma-cology and animal experiments.Methods The chemi-cal components and corresponding targets of SZS were collected through relevant platforms and databases,the insomnia and sleep disorder targets were retrieved,and the intersection targets of drugs and diseases were ob-tained.The protein interaction relationships were con-structed,and the Chinese medicinal herb-component-target-pathway network was drawn.Then database was used to analyze pathway enrichment.Based on the pre-dicted results,the effects of different SZS products on Kunming mice were evaluated through pentobarbital in-duced sleep test,behavioral analysis,brain tissue relat-ed gene mRNA levels,and plasma neurotransmitters.Results The target genes related to SZS and insomnia were acetylcholinesterase(ACHE),alpha-1B adrener-gic receptor(ADRA1B),solute carrier family 6(neu-rotransmitter transporter,serotonin),member 4(SLC6 A4),which might play a role through 9 related pathways and 69 biological processes such as calcium signaling pathway,salivary secretion,and so on.In vi-vo experiments found that SZS could reduce mouse ac-tivity,enhance the hypnotic effect of pentobarbital sodi-um,lower the levels of ACEE,ADRA1B,and SLC6A4 mRNA in cortex and hippocampus,and regulate the levels of acetylcholine,adrenaline,and other substances in plasma,all of which could be used in combination with raw and fried methods.The effect was proportion-al to the dosage of the drug.Conclusions SZS has sedative and hypnotic effects,and high doses of crude and parched SZS combined decoction have better effects.This effect may be caused by affecting the lev-els of neurotransmitters and their related receptors,me-diating the central nervous system.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

Objective: This cross-sectional investigation aimed to determine the incidence, clinical characteristics, prognosis, and related risk factors of olfactory and gustatory dysfunctions related to infection with the SARS-CoV-2 Omicron strain in mainland China. Methods: Data of patients with SARS-CoV-2 from December 28, 2022, to February 21, 2023, were collected through online and offline questionnaires from 45 tertiary hospitals and one center for disease control and prevention in mainland China. The questionnaire included demographic information, previous health history, smoking and alcohol drinking, SARS-CoV-2 vaccination, olfactory and gustatory function before and after infection, other symptoms after infection, as well as the duration and improvement of olfactory and gustatory dysfunction. The self-reported olfactory and gustatory functions of patients were evaluated using the Olfactory VAS scale and Gustatory VAS scale. Results: A total of 35 566 valid questionnaires were obtained, revealing a high incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain (67.75%). Females(χ2=367.013, P<0.001) and young people(χ2=120.210, P<0.001) were more likely to develop these dysfunctions. Gender(OR=1.564, 95%CI: 1.487-1.645), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), oral health status (OR=0.881, 95%CI: 0.839-0.926), smoking history (OR=1.152, 95%CI=1.080-1.229), and drinking history (OR=0.854, 95%CI: 0.785-0.928) were correlated with the occurrence of olfactory and taste dysfunctions related to SARS-CoV-2(above P<0.001). 44.62% (4 391/9 840) of the patients who had not recovered their sense of smell and taste also suffered from nasal congestion, runny nose, and 32.62% (3 210/9 840) suffered from dry mouth and sore throat. The improvement of olfactory and taste functions was correlated with the persistence of accompanying symptoms(χ2=10.873, P=0.001). The average score of olfactory and taste VAS scale was 8.41 and 8.51 respectively before SARS-CoV-2 infection, but decreased to3.69 and 4.29 respectively after SARS-CoV-2 infection, and recovered to 5.83and 6.55 respectively at the time of the survey. The median duration of olfactory and gustatory dysfunctions was 15 days and 12 days, respectively, with 0.5% (121/24 096) of patients experiencing these dysfunctions for more than 28 days. The overall self-reported improvement rate of smell and taste dysfunctions was 59.16% (14 256/24 096). Gender(OR=0.893, 95%CI: 0.839-0.951), SARS-CoV-2 vaccination status (OR=1.334, 95%CI: 1.164-1.530), history of head and facial trauma(OR=1.180, 95%CI: 1.036-1.344, P=0.013), nose (OR=1.104, 95%CI: 1.042-1.171, P=0.001) and oral (OR=1.162, 95%CI: 1.096-1.233) health status, smoking history(OR=0.765, 95%CI: 0.709-0.825), and the persistence of accompanying symptoms (OR=0.359, 95%CI: 0.332-0.388) were correlated with the recovery of olfactory and taste dysfunctions related to SARS-CoV-2 (above P<0.001 except for the indicated values). Conclusion: The incidence of olfactory and taste dysfunctions related to infection with the SARS-CoV-2 Omicron strain is high in mainland China, with females and young people more likely to develop these dysfunctions. Active and effective intervention measures may be required for cases that persist for a long time. The recovery of olfactory and taste functions is influenced by several factors, including gender, SARS-CoV-2 vaccination status, history of head and facial trauma, nasal and oral health status, smoking history, and persistence of accompanying symptoms.

Aging-induced changes in the immune system are associated with a higher incidence of infection and vaccination failure. Lymph nodes, which filter the lymph to identify and fight infections, play a central role in this process. However, careful characterization of the impact of aging on lymph nodes and associated autoimmune diseases is lacking. We combined single-cell RNA sequencing (scRNA-seq) with flow cytometry to delineate the immune cell atlas of cervical draining lymph nodes (CDLNs) of both young and old mice with or without experimental autoimmune uveitis (EAU). We found extensive and complicated changes in the cellular constituents of CDLNs during aging. When confronted with autoimmune challenges, old mice developed milder EAU compared to young mice. Within this EAU process, we highlighted that the pathogenicity of T helper 17 cells (Th17) was dampened, as shown by reduced GM-CSF secretion in old mice. The mitigated secretion of GM-CSF contributed to alleviation of IL-23 secretion by antigen-presenting cells (APCs) and may, in turn, weaken APCs' effects on facilitating the pathogenicity of Th17 cells. Meanwhile, our study further unveiled that aging downregulated GM-CSF secretion through reducing both the transcript and protein levels of IL-23R in Th17 cells from CDLNs. Overall, aging altered immune cell responses, especially through toning down Th17 cells, counteracting EAU challenge in old mice.

ObjectiveTo investigate the effects of Anmeidan （AMD） on neuronal structure and neuronal marker protein expression in the hippocampal CA1 region of sleep-deprived （SD） rats. MethodRats were randomly divided into control group， model group， an AMD group （9.09 g·kg^-1·d^-1）， and melatonin group （0.27 g·kg^-1·d^-1）. Rats in the control group and the model group received equal volumes of physiologicol saline. The SD model was induced by the self-made sleep deprivation box for four weeks. Ethovision XT system detected and analyzed the spontaneous behaviors of rats. The histomorphology of neurons in the hippocampal CA1 region was observed by hematoxylin-eosin （HE） staining and Nissl staining， and the changes in Nissl bodies were observed by Nissl staining. The ultrastructure of hippocampal cells was observed by transmission electron microscopy （TEM）. Immunohistochemistry was used to detect the expression of glial fibrillary acidic protein （GFAP）， microtubule-associated protein 2 （MAP2）， nestin， and neuronal nuclei （NeuN） in the CA1 region. ResultCompared with the control group， the model group showed longer distance， increased average activity speed， cumulative duration， average body fill， and higher activity frequency （P<0.01）. Besides， the neurons in the CA1 region were reduced in number with disorganized arrangement， wrinkled nuclei， deeply stained cytoplasm， reduced Nissl bodies， swollen and deformed mitochondria， shortened cristae， and swollen Golgi vesicles. Furthermore， the mean integral absorbance （IA） value of GFAP increased and those of MAP2， nestin， and NeuN decreased （P<0.01）. Compared with the model group， the AMD group showed shortened distance traveled， lower average activity speed， shorter cumulative duration， decreased average body fill， and reduced activity frequency （P<0.05， P<0.01）. Moreover， the neurons in the CA1 region were relieved from damage with increased cell number， clear nuclei and cytoplasm， increased Nissl bodies， and relieved mitochondrial damage. The IA value of GFAP decreased and those of MAP2， nestin， and NeuN increased （P<0.05， P<0.01）. ConclusionAMD can improve structural damage of neurons in the hippocampal CA1 region of sleep-deprived rats， which may be achieved by decreasing GFAP expression and increasing MAP2， nestin， and NeuN expression.

ObjectiveTo investigate the effect of Anmeidan （AMD） on biological rhythm and related protein expression in sleep-deprived rats. MethodA total of 80 SD rats were randomized into control group （Ctrl， equivalent volume of saline）， model group （SD， equivalent volume of saline）， AMD group （9.09 g·kg^-1·d^-1）， and melatonin group （MT， 0.27 g·kg^-1·d^-1）. Insomnia was induced in rats by self-made sleep deprivation box （4 weeks）. Circadian rhythm of spontaneous activity was evaluated by spontaneous activity video analysis system. Morphology of hypothalamus was observed based on hematoxylin-eosin （HE） staining， and the histomorphology of hypothalamus neurons and the Nissl's bodies based on Nissl staining. Western blotting was employed to detect the expression of hypothalamic proteins in cAMP-response element binding protein （CREB）/clock gene period （Per） pathway， and immunohistochemistry the expression of brain and muscle ARNT-like protein 1 （Bmal1）， Clock， Per1， and cryptochrome circadian regulator 1 （Cry1）. ResultThe model group demonstrated circadian rhythm disorder， as manifested by the significant increase in activity time in 6 designated time periods compared with the control group， and the rise in the activity speed and frequency （P<0.01）. Moreover， model group showed decrease in number of neurons which were sparsely arranged with shrunken or fragmented nuclei， reduction in number and loss of Nissl's bodies with light color， and drop in the relative expression of p-CREB and Per1， and the positive rate of Bmal1， Clock， Per1， and Cry1 （P<0.01）. Compared with model group， AMD group demonstrated reduction in time， speed， and frequency of activity （P<0.01）. Moreover， the AMD group also showed alleviation of neuronal damage （P<0.01）， and increase in the number of neurons with clear nuclei and cytoplasm in some， and the number of Nissl's bodies. AMD raised the expression of p-CREB and Per1 proteins， and the positive rate of Bmal1， Clock， Per1， and Cry1 （P<0.01）. ConclusionAMD ameliorated spontaneous circadian rhythm of sleep-deprived rats by regulating CREB/Per signaling pathway and further increasing the expression of Bmal1， Clock， Per1， and Cry1.

Sleep plays an important role in energy balance. As reported， sleep disorder is an important risk factor for metabolic diseases. Controlling the relationship between energy metabolism and sleep can affect sleep homeostasis and body metabolic rate. Chinese medicine， with remarkable curative effects in the prevention and treatment of insomnia， has the characteristics of green， safety， and few side effects， and attracts extensive attention of scholars in the world. In recent years， remarkable progress has been made in the research on the mechanism of Chinese medicine in interfering with sleep. This paper reviewed the research progress of mind-tranquilizing Chinese medicines， such as compounds （pterostilbene）， Chinese medicinal drugs （Ziziphi Spinosae Semen）， and Chinese medicinal prescriptions （Jiaotaiwan， Suanzaoren tang， Tianwang Buxindan， Anmeidan， Banxia Houpotang， Qihuo decoction， Songyu Anshen prescriptions， and Shuxie Yihao prescriptions） in the treatment of sleep disorders by regulating energy metabolism. The findings revealed that Chinese medicine can intervene in the sleep deprivation model by affecting metabolism-related pathways such as material metabolism， mitochondrial function， oxidative stress and inflammatory response， appetite system， and biological clock system. In terms of frequency of use， the top drugs are Ziziphi Spinosae Semen， Poria， Schisandrae Chinensis Fructus， and Salviae Miltiorrhizae Radix et Rhizoma which affect heart and liver meridians to regulate blood circulation， ensure energy supply， and play the role of nourishing the heart and tranquilizing the mind. The present paper summarized the effects and mechanisms of Chinese medicine in the treatment of insomnia and other sleep disorders from the perspective of energy metabolism to provide references for further research and exploration of diseases in the future.
