BackgroundThe global prevalence of depressive disorders is high， with a significant treatment gap remaining. Escitalopram oxalate， as a commonly used antidepressant in clinical practice， has a single target and is prone to cause adverse reactions such as gastrointestinal discomfort. The traditional Mongolian medicine Zadi-5 pills has a multi-target anti-depression mechanism and unique advantages such as improving the intestinal flora. However， there is currently a lack of randomized controlled trial evidence for the combined treatment of first-episode depression， along with insufficient research on its metabolic safety and potential drug interactions. ObjectiveTo explore the efficacy and safety of Zadi-5 pills combined with escitalopram oxalate in the treatment of the first-episode depression， so as to provide references for Mongolian medicine in depression management. MethodsA randomized controlled trial was conducted. A total of 103 patients with first-episode depression who were treated in the outpatient or inpatient departments of the Inner Mongolia Autonomous Region Mental Health Center from January 2023 to December 2024 and met the diagnostic criteria for depressive episode as defined in International Classification of Diseases， tenth edition （ICD-10） were included. Random numbers were generated using the RAND function in Excel software， and the patients were divided into the study group （n=52） and the control group （n=51）. Both groups received escitalopram oxalate treatment， starting from 5 mg/d and gradually increasing to 20 mg/d. The study group additionally received Zadi-5 pills， 13 pills per day. The treatment duration for both groups was 6 weeks. Before treatment and at the 2^nd， 4^th， and 6^th weeks of treatment， the severity of depressive symptoms was evaluated using the Hamilton Depression Scale-24 item （HAMD-24）. At these time points， blood was collected on an empty stomach at 7∶00 for the detection of liver function （aspartate aminotransferase， alanine aminotransferase）， triglycerides， and the blood concentration of escitalopram oxalate. ResultsA total of 100 patients completed the study， with 50 cases in the study group and the control group. The results of the repeated measures ANOVA showed that the interaction effect between group and time in the HAMD-24 score was statistically significant （F _interaction= 18.070， P<0.01）. At the end of the 4^th and 6^th weeks of treatment， the HAMD-24 score of the study group was lower than those of the control group （P<0.05）. At each time point after treatment， the reduction rate of the HAMD-24 score in the study group was higher than those of the control group， and the differences were all statistically significant （P<0.05）. The interaction effect between the triglyceride level groups and time was statistically significant （F_interaction=3.381， P<0.05）.After treatment， the triglyceride levels in the study group showed a downward trend， while those in the control group showed an upward trend. There was no statistically significant interaction effect between the groups and time for liver function （aspartate aminotransferase and alanine aminotransferase） and the blood concentration of escitalopram oxalate （P>0.05）. ConclusionCompared with escitalopram oxalate treatment alone， the combination of Zadi-5 pills and escitalopram oxalate is more effective in treating the first-episode depression， without increasing the risk of liver damage. The combined medication may have a potential beneficial effect on lipid metabolism. ［Funded by Inner Mongolia Autonomous Region Health Science and Technology Planning Project （number， 202202107）］

BACKGROUND:Long non-coding RNAs(lncRNAs),as important regulators of the inflammatory response,are involved in the immune-inflammation-brain crosstalk mechanism after ischemic stroke and have the potential to become a therapeutic agent for neurological dysfunction after ischemic stroke. OBJECTIVE:To analyze and summarize the molecular mechanism of lncRNA acting on glial cells involved in the neuroimmuno-inflammatory cascade response after ischemic stroke and the associated signaling pathways,pointing out that lncRNAs have the potential to regulate inflammation after ischemic stroke. METHODS:PubMed was searched using the search terms of"ischemic stroke,long non-coding RNA,neuroinflammation,immune function,signal pathway,microglia,astrocytes,oligodendrocyte,mechanism,"and 63 relevant documents were finally included for review. RESULTS AND CONCLUSION:In the early stage of ischemic stroke,the death of nerve cells due to ischemia and hypoxia activates the innate immune response of the brain,promoting the secretion of inflammatory factors and inducing blood-brain barrier damage and a series of inflammatory cascades responses.As an important pathogenesis factor in ischemic stroke,the neuroimmuno-inflammatory cascade has been proved to seriously affect the prognosis of patients with ischemic stroke,and it needs to be suppressed promptly in the early stage.Neuroinflammation after ischemic stroke usually induces abnormal expression of a large number of lncRNAs that mediate a series of neuro-immune-inflammatory crosstalk mechanisms through regulating the polarization of microglia,astrocytes and oligodendrocytes to exert post-stroke neuroprotective effects.LncRNAs,as important regulatory factors of the inflammatory response,inhibit the neuroimmuno-inflammatory cascade response after ischemic stroke through regulating nuclear factor-κB,lncRNA-miRNA-mRNA axis,Rho-ROCK,MAPK,AKT,ERK and other signaling pathways to effectively improve neurological impairment after ischemic stroke.Most of experimental studies on the interaction between lncRNAs and ischemic stroke are based on a middle cerebral artery occlusion model or a cerebral ischemia-reperfusion injury model,but no clinical trials have been conducted.Therefore,it remains to be further explored about whether lncRNAs can be safely applied in clinical practice.At present,there are many therapeutic drugs for the treatment of ischemic stroke,but there are relatively few studies on the application of lncRNAs,exosomes and other transplantation technologies for the treatment of ischemic stroke using tissue engineering technology,which need to be further explored.lncRNA has become an important target for the treatment of ischemic stroke with its relative stability and high specificity.In future studies,more types of inflammatory lncRNAs that function under ischemic-hypoxia conditions should continue to be explored,in order to provide new research directions for the treatment of neuroinflammation after ischemic stroke.

Cerebral organoids are three-dimensional nerve cultures induced by embryonic stem cells(ESCs)or induced pluripotent stem cells(iPSCs)that mimic the structure and function of human brain.With the continuous optimization of cerebral organoid culture technology and the combination with emerging technologies such as organ transplantation,gene editing and organoids-on-chip,complex brain tissue structures such as functional vascular structures and neural circuits have been produced,which provides new methods and ideas for studying human brain development and diseases.This article reviews the latest advances in brain organoid technology,describes its application in neurological diseases and advances in stroke modeling and transplantation treatment.

Post-stroke cognitive impairment(PSCI)is mainly manifested as learning and memory disorders.Highly enriched RNA m6A methylation modification in mammalian brain is involved in glial cell-mediated neuroinflammation.Given that neuroinflammation is the main mechanism for neural damage and spatial and memory impairment of PSCI,it is speculated that RNA m6A methylation modification can regulate the inflammatory response of glial cells after stroke to improve PSCI.This review summarizes and analyzes the role of RNA m6A methylation modification in the development of PSCI and analyzes its detailed mechanism of regulating glial cell-mediated inflammation,which will provide reference for researchers in this field.

Post-stroke cognitive impairment(PSCI)is a common complication after stroke,which significantly affects quality of life.However,the pathogenesis has not been fully explained.Increasing evidence has shown that the mechanism of programmed cell death(PCD)is related to PSCI,including apoptosis,necroptosis,pyroptosis,PANoptosis,parthanatos,and ferroptosis.Therefore,it is crucial to clearly understand the various mechanisms of PCD and their relationship with PSCI,and to elucidate the role of PCD in PSCI pathogenesis.The article reviews six PCD pathways related to PSCI,summarizes their mechanisms of action in PSCI,and elucidates the possible crosstalk among pathways to provide a basis for clinical targeting of regulatory factors in the PCD pathway for PSCI treatment.

Objective:To compare the application effect among Western Ontario and McMaster University Osteoarthritis Index (WOMAC) scale, Medical Outcomes Study 36-item Short Form (SF-36) scale and "Assessment for Therapeutic Efficacy on Kashin-Beck Disease" (WS/T 79-2011) standard in the evaluation of therapeutic effect of patients with Kashin-Beck disease, which could provide basis for the treatment evaluation of patients with Kashin-Beck disease.Methods:A total of 213 patients with Kashin-Beck disease in Gansu Province were investigated. WOMAC scale, SF-36 scale and standard of WS/T 79-2011 were used to analyze the quality of life of patients before and after treatment. The reliability, construct validity, content validity, discriminant validity of WOMAC and SF-36 scales were compared. Correlation between WOMAC, SF-36 scales and standard of WS/T 79-2011 were evaluated.Results:Both WOMAC and SF-36 scales had good construct validity and content validity (construct validity showed WOMAC and SF-36 scales contained 1 and 2 common factors, respectively; content validity showed WOMAC and SF-36 scales contained 3 and 8 common factors, respectively). The reliability and discriminant validity of WOMAC scale were better than those of SF-36 seale (reliability showed WOMAC reliability coefficient ≥0.934, the reliability coefficient of SF-36 scale was ranged from 0.386 to 0.999. Discriminant validity showed there were differences in 3 dimensions of the WOMAC scale before and after treatment, while there were differences in 6 out of 8 dimensions of the SF-36 scale). The correlation coefficients between WOMAC scale and standard of WS/T 79-2011 ranged from 0.175 to 0.437, the correlation coefficients between SF-36 scale and standard of WS/T 79-2011 ranged from - 0.434 to - 0.099 ( P < 0.05). Conclusion:The reliability, discriminant validity and correlation with the standard of WS/T 79-2011 of WOMAC scale are better than those of SF-36 scale in efficacy evaluation of patients with Kashin-Beck disease.

Objective:To further investigate the prevalence of tea-drinking-borne endemic fluorosis in Tianzhu Tibetan Autonomous County (referred to as Tianzhu) Gansu Province, to accurately master the information of patients with tea-drinking-borne endemic fluorosis, and to provide scientific basis for popularizing low fluoride brick tea and carrying out patient rescue and treatment.Methods:From 2019 to 2020, according to the "Investigation Plan of Tea-drinking-borne Endemic Fluorosis in Gansu Province in 2019", in the administrative villages with the habit of drinking and selling tea, drinking water samples of local residents were collected to detect the fluorine content of water in Tianzhu, 10 families were randomly selected in each village, basic situation of each family member and the drinking situation of tea were investigated, and tea samples were collected to determine the fluorine content. At the same time, all children aged 8 - 12 in the investigation village were examined for dental fluorosis; clinical examination of bone and joint symptoms and signs was conducted for permanent residents over the age of 25 in the investigation village (excluding 25 years old), X-ray examination of bone and joint was conducted for patients with clear clinical symptoms or signs of skeletal fluorosis, and urine samples were collected to detect urinary fluorine. Ion selective electrode method was used to detect fluorine in water, tea and urine, and dental fluorosis was diagnosed by "Diagnosis of Dental Fluorosis" (WS/T 208-2011), and the "Diagnostic criteria for Endemic Skeletal Fluorosis" (WS 192-2008) was used for the diagnosis of skeletal fluorosis.Results:A total of 161 water samples were collected, and the fluorine content in water was from 0.07 to 0.68 mg/L, which met the domestic drinking water standard ( < 1.0 mg/L). A total of 1 644 side-tea samples were collected, and the annual per capita consumption of side-tea of permanent residents over 16 years old was 1.05 kg. The average fluoride content of tea was 601.99 - 991.38 mg/kg. According to the detection results of tea fluorine, 16 administrative villages with an average daily intake of tea fluorine more than 3.5 mg/d were screened, the lowest intake was 4.91 mg/d in Tuta Village Danma Township, and the highest intake was 18.98 mg/d in Huashan Village Maozang Township. A total of 253 children aged 8 - 12 years old in 14 administrative villages were investigated. There were 3 cases of very mild dental fluorosis, 2 cases of mild dental fluorosis, and 1 case of moderate dental fluorosis. The overall prevalence of dental fluorosis was 4.74% (12/253). The clinical examination of bone and joint symptoms and signs was carried out for 3 100 permanent adults over the age of 25 (excluding the age of 25) in 15 administrative villages. The X-ray examination of bone and joint was carried out for 104 patients with definite clinical symptoms and/or signs of skeletal fluorosis. Six patients with skeletal fluorosis were diagnosed, including 3 mild and 3 severe, aged 56 - 76 years. The average urinary fluorine in the investigated villages was 0.73 - 4.74 mg/L (the number of investigated was 3 100). According to the determination and classification standards of tea-drinking-borne fluorosis area, Tuta Village Danma Township, Xiding Village Dahonggou Township and Daiqian Village Zhuaxixiulong Township were determined to be in the mild area of tea-drinking-borne endemic fluorosis, while Nannigou Village Zhuaxixiulong Township was in the moderate area of tea-drinking-borne endemic fluorosis.Conclusion:Tea-drinking-borne endemic fluorosis is prevalent in Tianzhu, Gansu Province, and targeted prevention methods and control measures need to be taken.
