BACKGROUND:Successful uterine spiral artery remodeling is necessary for normal pregnancy,in which vascular smooth muscle cells are important cells.Interferon-γ is associated with the loss of vascular smooth muscle cells during early pregnancy.However,the specific mechanism is not fully understood. OBJECTIVE:To investigate the effects of interferon-γ on migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway. METHODS:Human vascular smooth muscle cells were divided into control group and interferon-γ group.The control group was cultured normally,and the interferon-γ group was treated with 10 ng/mL interferon-γ for 24 hours.The migration ability of vascular smooth muscle cells was detected by Transwell assay.The apoptosis of vascular smooth muscle cells was detected by TUNEL assay and flow cytometry.The mRNA expression levels of NLRP3 and caspase-1 were detected by qPCR.Western blot assay was utilized to detect NLRP3,caspase-1,and cleaved N-terminal GSDMD protein expression levels. RESULTS AND CONCLUSION:Compared with the control group,the migration ability and apoptosis rate of vascular smooth muscle cells in interferon-γ group were significantly increased(P<0.05).Compared with the control group,the mRNA expression levels of NLRP3 and caspase-1 in vascular smooth muscle cells of interferon-γ group were significantly increased(P<0.05).Compared with control group,the expression levels of NLRP3,caspase-1,and cleaved N-terminal GSDMD protein in vascular smooth muscle cells in the interferon-γ group were significantly increased(P<0.05).The results suggest that interferon-γ may regulate the migration and apoptosis of vascular smooth muscle cells through NLRP3/caspase-1/GSDMD pyroptosis pathway.

Objective:To evaluate the effect of propofol on parvalbumin (PV) neurons in the medical prefrontal cortex(mPFC)of rats with social behavior disorders induced by chronic sleep deprivation.Methods:Forty-two SPF male Sprague-Dawley rats, aged 8 weeks, weighing 200-250 g, were divided into 3 groups ( n=14 each) using a random number table method: control group (group Con), chronic sleep deprivation plus natural sleep group (group CSD+ NS), and chronic sleep deprivation plus propofol group (group CSD+ Pro). Sleep deprivation model was established by the modified multiple platform method, the rats were placed in the sleep-deprivation tank for 20 h a day (14: 00-10: 00), and allowed to sleep naturally for 4 h (10: 00-14: 00) a day for 28 consecutive days. Propofol 40 mg/kg was intraperitoneally injected for 28 consecutive days after sleep deprivation in CSD+ Pro group. While the equal volume of 10% fat emulsion was given in Con and CSD+ NS groups. After the end of sleep deprivation, a three-box social experiment was used to detect the social behavior of rats, and the number of the PV positive cells and density of the perineuronal network (PNN) in the mPFC area were measured by immunofluorescence. Results:Compared with group Con, the pertentage of rapid eye movement sleep and sniffing time preference coefficients for the strange rat 1 in the first stage and for the strange rat 2 in the second stage were significantly decreased, and the number of the PV positive cells and density of PNN in the mPFC area were decreased in group CSD+ NS ( P<0.05). Compared with group CSD+ NS, the sniffing time preference coefficients for the strange rat 1 in the first stage and for the strange rat 2 in the second stage were significantly increased, the number of the PV positive cells and density of PNN in the mPFC area were increased( P<0.05), and no significant change was found in the percentage of the rapid eye movement sleep in group CSD+ Pro. Conclusions:Propofol probably increases the number and function of PV neurons in the mPFC and ameliorates sleep deprivation-induced social behavior disorders in sleep-deprived rats.

The theory of “rhythmic equilibrium” is developed based on the idea of sharing the same laws between nature and human, and by integrating with the medical concept of homeostasis of calm yin and sound yang. "Rhythmic instability" runs through the entire process of the occurrence and development of myopia, covering four aspects including imbalance of rhythm (high-risk period of myopia), imbalance of qi and blood (premyopia), imbalance of sinew-membranes (low myopia), and imbalance of essence and blood (high myopia). The treatment should focus on adjusting the rhythm and harmonizing situation, which can help balance yin and yang, and nourish the eye system. For high-risk period of myopia, adjusting sleeping time and increasing outdoor activities are stressed to adjust the rhythm in a timely manner. In the stage of premyopia, appropriate techniques of traditional Chinese medicine (TCM) such as pressing needles can be added to harmonize qi and blood. In the period of low myopia, appropriate TCM techniques such as pressing needles and ear acupuncture are mainly used, supplemented by modified Danggui Buxue Decoction (当归补血汤) to soften tendons and unblock collaterals. During the period of high myopia, it is recommended to control the development of existing disease and put focus on nourishing essence and blood, usually with Zhujing Pill (驻景丸) or modified Siwu Wuzi Decoction (四物五子汤) to restore the stability of the eyes and the whole body.

Neurodegenerative diseases are a group of diseases caused by degeneration and dysfunction of the cells and tissues of the central nervous system, mainly including Alzheimer's disease (AD), Parkinson's disease (PD), and epilepsy. A common clinical manifestation of these diseases is cognitive decline. Neurodegenerative diseases are more common in the elderly. As population aging is aggravating, neurodegenerative diseases have aroused increasing concern since they seriously affect human health and quality of life. The pathogenesis of neurodegenerative diseases is complex, mainly related to mitochondrial dysfunction, apoptosis, neurotoxin, neurotransmitter abnormalities, oxidative stress, and inflammation. Although western drugs on the market can attenuate the symptoms of neurodegenerative diseases, they may induce severe adverse reactions and are thus not conducive to long-term use by the patients. The Chinese herbal medicine Angelicae Sinensis Radix was first recorded in the Shennong's Classic of Materia Medica (Shen Nong Ben Cao Jing). It has the functions of activating blood, tonifying blood, modulating the immune system, regulating menstruation, and relieving pain. This paper summarizes the research progress in the effects of Angelicae Sinensis Radix and the prescriptions containing this medicine on neurodegenerative diseases in recent 10 years, aiming to provide a reference for the future application and research of Angelicae Sinensis Radix in the treatment of neurodegenerative diseases.

Objective This study aimed to identify differentially methylated genes (DMGs) associated with natural killer cells in patients with autoimmune thyroiditis (AIT),focusing on the influence of varying water iodine exposure levels. Methods Participants were divided into categories based on median water iodine (MWI) concentrations:iodine-fortified areas (IFA,MWI<10 μg/L),iodine-adequate areas (IAA,40 ≤ MWI ≤ 100μg/L),and iodine-excessive areas (IEA,MWI>300 μg/L). A total of 176 matched AIT cases and controls were recruited and divided into 89,40,and 47 pairs for IFA,IAA,and IEA,respectively. DMGs were identified using 850K BeadChip analysis for 10/10 paired samples. Validation of DNA methylation and mRNA expression levels of the DMGs was conducted using MethylTarget? and QRT-PCR for 176/176 paired samples. Results KLRC1,KLRC3,and SH2D1B were identified as significant DMGs. Validation revealed that KLRC1 was hypomethylated and highly expressed,whereas KLRC3 was hypermethylated and highly expressed in individuals with AIT. Furthermore,KLRC1 was hypomethylated and highly expressed in both IFA and IEA. Conclusion The DNA methylation status of KLRC1 and KLRC3 may play crucial roles in AIT pathogenesis. Additionally,DNA methylation of KLRC1 seems to be influenced by different iodine concentrations in water.
