Autosomal dominant polycystic kidney disease （ADPKD） is a systemic hereditary renal disorder and can affect multiple organs， and congenital hepatic fibrosis is one of the manifestations of liver involvement and is an important complication of ADPKD. Symptomatic management is currently the main treatment method for this disease， and disease-specific drugs such as tolvaptan have limited indications and cannot correct the underlying genetic defect. This article reports a case of ADPKD with congenital hepatic fibrosis， and sirolimus was identified as the individualized treatment regimen based on peripheral blood functional genomic analysis and drug sensitivity prediction platform. The patient achieved significant improvements in symptoms and quality of life after treatment， with a stable kidney volume. This case shows that functional genomics has a potential value in guiding individualized treatment of rare genetic disorders， which provides new treatment ideas and practice paths for similar patients.

BACKGROUND:When exercising in a cold environment,the body's inflammatory response is affected by both low temperature and exercise intervention,and its impact and mechanism remain to be explored.OBJECTIVE:To explore the effects and mechanisms of cold water swimming on inflammatory response of rats based on transcriptome sequencing technology.METHODS:40 male SD rats were randomly divided into room temperature control group,room temperature swimming group,cold water control group,and cold water swimming group,with 10 rats in each group.The room temperature control group had no intervention and was free to eat.The room temperature swimming group received swimming at 30 min/time,6 times/week,for 5 weeks;the water temperature was(28±2)℃,and the water depth was 35 cm.In the cold water control group,the rats were placed in a water tank with a depth of 3 cm;the water temperature was(18±2)℃,and they were free to move.The cold water swimming group received swimming at 30 min/time,6 times/week,for 5 weeks;the water temperature was(18±2)℃,and the water depth was 35 cm.Enzyme-linked immunosorbent assay was used to detect the levels of serum interleukin-6,tumor necrosis factor-α,and high-sensitivity C-reactive protein.Based on the transcriptome sequencing results,differentially expressed genes were screened to draw Venn diagrams and heat maps,and Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis were performed.The protein-protein interaction network was used to screen core genes.RT-qPCR was used to detect the mRNA expression of IRF7,OAS2,and OASL in rat spleen tissue.RESULTS AND CONCLUSION:(1)The ELISA results showed that compared with the room temperature control group,the levels of various inflammatory indicators in the room temperature swimming group and the cold water swimming group were significantly increased(P＜0.05),and there was no significant difference in the cold water control group.Compared with the room temperature swimming group,there was no significant difference in the expression of inflammatory indicators in the cold water swimming group.Compared with the cold water control group,the expressions of interleukin-6 and tumor necrosis factor-α in the cold water swimming group showed an upward trend,and high-sensitivity C-reactive protein increased significantly(P＜0.05).(2)Transcriptome analysis:Venn diagram showed that there were 39 differentially expressed genes affected by the dual factors of temperature and exercise intervention.Cluster heat map analysis results showed that the overall gene expression trends of the room temperature swimming group and the cold water swimming group were similar,and the cold water control group showed an opposite trend.Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analysis results showed that differentially expressed genes were enriched in the immune system,locomotion,nucleic acid-binding transcription factor activity,NOD-like receptor signaling pathways and other pathways.The number of genes enriched in the NOD-like receptor signaling pathway was relatively large,and the q value was small,which may be a key pathway.The protein-protein interaction network screened out IRF7,OAS2,OASL,IFIT2,IFIT3 and other core genes.(3)RT-qPCR verification results showed that compared with the room temperature control group,the expressions of IRF7,OAS2 and OASL were significantly increased in the room temperature swimming group and the cold water swimming group(P＜0.01),and there was no significant difference in the cold water control group.Compared with the cold water control group,the expression of each gene was significantly increased in the cold water swimming group(P＜0.01).(4)It is concluded that cold water swimming can promote inflammatory response,and its mechanism may be regulated through the NOD-like receptor signaling pathway.

Objective:To investigate the effect of monocular form deprivation (MD) during the pre-critical period of visual development on the density and morphology of dendritic spines in mouse primary visual cortex (V1) neurons.Methods:Twenty SPF male C57BL/6J mice with eyes opened on postnatal day 14 (P14) were selected and divided into MD and control groups using a random number table, with 10 mice in each group.The MD group was fed to P18 after 4 days of MD in the right eye, and the control group was raised to P18 under the same feeding conditions.All mice were decapitated after cardiac perfusion, and the sections were stained with the cell membrane fluorescent probe 1, 1′-dioctadecyl-3, 3′, 3′-tetramethylindocarbocyanine perchlorate, and imaged by laser scanning confocal microscopy to observe and compare the differences in density and morphology of dendritic spines in bilateral V1 neurons between the control group and the MD group.This study was approved by the Animal Ethics Committee of Tianjin Medical University (No.TMUaMEC2022004).Results:The total density of dendritic spines in the V1 area on the left side of the control group, the right side of the control group, the left side of the MD group, and the right side of the MD group were (7.57±0.25), (7.42±0.25), (6.54±0.18), and (7.51±0.29)spines/10 μm, respectively, with a statistically significant overall difference ( F=3.818, P<0.05).The total density of dendritic spines in the left V1 area of mice in the MD group was significantly lower than that in the left side of the control group and the right side of the MD group, and the differences were statistically significant (both P<0.05).There was a significant difference in the proportion of the four types of dendritic spines in V1 neurons on both sides between the two groups ( χ2=26.295, P=0.002).There was a significant difference in the proportion of the four types of dendritic spines between the left V1 of the MD group and the left and right V1 of the control group (both P<0.008 3).There was a significant difference in the filopodia-type dendritic spine density in bilateral V1 neurons between the two groups ( F=3.253, P<0.05).Compared with the left V1 area of the control group, the density of filopodia-type dendritic spines in the left V1 area of the MD group decreased significantly, with a statistical significance ( P<0.05).There was no significant difference in the density of thin-type, mushroom-type, and stubby-type dendritic spines in bilateral V1 area neurons between the two groups ( F=1.760, 2.618, 1.749; all P>0.05). Conclusions:MD during the pre-critical period of visual development can cause a decrease in the total density of dendritic spines and significant changes in the compositional proportions in the V1 contralateral to the deprived eye, and is mainly manifested by a decrease in the number of filopodia, suggesting that abnormal visual experience can cause plastic changes in the number and structure of synapses in the visual cortex during the pre-critical period of visual development.

Breast cancer, as a malignant tumor with a high incidence rate in women, seriously endangers the life health and safety of women. Its pathogenesis and treatment strategies are still the hot and difficult points in current research. More and more studies have shown that the occurrence and development of breast cancer is closely related to the microbial community in intestinal tissue and breast tissue, and the microbial community in human tissue may promote or inhibit the occurrence of breast cancer through various ways and mechanisms. Defining the relationship between microbial communities and breast cancer will provide new directions for the prevention and comprehensive treatment of breast cancer.
