ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

Objective:To explore the risk factors of suicidal ideation in community residents in Shandong province,China,and to establish a prediction model and a nomogram for the risk of suicidal ideation.Methods:To-tally 11 087 community residents in Jining City,Zoucheng City,and Weifang City,Shandong Province,were recrui-ted as the study subjects.The general information questionnaire,Composite International Diagnostic Interview-3.0,General Anxiety Disorder-7,were used to collect demographic information,mental health status,family information,and lifestyle using a computer-assisted interview system to conduct face-to-face interview.LASSO regression and binary logistic regression analyses were used to develop a nomogram model of the risk of suicidal ideation.Results:Young people,female,smoking,non-new town residents,no physical exercise,difficulty approaching people,anxiety symptoms and depression were effective predictors of suicidal ideation.The area under the curve(AUC)of the training set(AUC)was 0.89(95％CI:0.85-0.93)and AUC of the validation set(AUC)was 0.83(95％CI:0.75-0.92).Conclusion:The nomogram prediction model constructed in this study on suicidal ideation in com-munity residents has a high degree of differentiation and accuracy.It could be used to screen people at high risk of suicide and provide intervention to suicidal ideation in community residents.

AIM To investigate the effects of volatile oil from Acorus tatarinowii Schott(A.tatarinowii)on neuroinflammation in a rat model of tic disorders.METHODS The SD rats were randomly divided into the blank group(8 rats)and the model group(40 rats).The rat models of tic disorders established successfully by intraperitoneal injection of iminodiapropionitrile(IDPN)were further divided into the model group,the tiapride group and the high-dose,moderate-dose and low-dose A.tatarinowii volatile oil groups,with 8 rats in each group.The 4-week intragastric treatment of respective drug was initiated the next day after the completion of modeling,and normal saline was dosed upon the blank group and the model group,during which the rats' behavioral changes were assessed by stereotyped behavior and motor behavior score every week.After the administration,the rats had their morphological changes of striatal neurons observed by Nissl staining;their levels of TGF-β,IL-10,TNF-αand IL-1β in serum and striatum detected by ELISA;their striatal protein expressions of CX3CL1 and CX3CR1 detected by Western blot and immunohistochemistry;and their striatal expressions of M1,M2 microglia marker proteins CD86,CD206,SYN and PSD-95 detected by immunofluorescence co-staining.RESULTS Compared with the model group,the A.tatarinowii volatile oil groups demonstrated improved twitch-like behavior;decreased scores of motor behavior and rigid behavior(P＜0.01);alleviated damage of Nissl bodies in neurons;increased serum and striatum levels of TGF-β and IL-10(P＜0.05,P＜0.01);decreased levels of TNF-α and IL-1β(P＜0.01);decreased striatal protein expressions of CX3CL1 and CX3CR1(P＜0.01);increased protein expressions of PSD95 and SYN(P＜0.05,P＜0.01);and decreased CD86/Iba1(P＜0.01)and increased CD206/Iba1(P＜0.01)in terms of the fluorescence intensity.CONCLUSION A.tatarinowii volatile oil contributes an anti-tic effect and improves the neuroinflammation in the brain of the rat model of tic disorders by promoting the transformation of microglia into M2 type via CX3CL1/CX3CR1 signal axis.

Objective:To study the effects of arsenic exposure on neurological function including voluntary motor ability, anxiety, and short-term memory ability of rats, as well as its impact on the expression levels of synaptic function related genes such as neuropeptide 1 (NLGN1), glutamate receptor 2A (NR2A), and postsynaptic density protein 95 (PSD95).Methods:Forty 3-week-old male specific pathogen free (SPF) grade Wistar rats [weighing (453.97 ± 35.68) g] were selected and divided into four groups using a random number table: 0 (control group) and 2, 10, and 50 mg/L arsenic exposure groups, with 10 rats in each group. They were given deionized water and 2, 10, and 50 mg/L sodium arsenite solutions for 12 weeks, respectively. The open field experiment and Y-maze experiment were used to test the voluntary motor ability, anxiety, and short-term memory ability of rats. Nissl staining was used to observe the pathological damage of the hippocampus in the brain. Real time fluorescence quantitative PCR and Western blot were used to detect the mRNA and protein expression levels of NLGN1, NR2A, and PSD95 in the hippocampus, respectively.Results:The results of the open field experiment revealed that the horizontal movement distances of rats in the 2 and 10 mg/L arsenic exposure groups were reduced compared to the control group, the movement distances in the central area in the 2, 10, and 50 mg/L arsenic exposure groups were reduced compared to the control group, and the residence time in the central area in the 10 and 50 mg/L arsenic exposure groups was reduced compared to the control group ( P < 0.05). The results of Y-maze experiment showed that the retention time of new arms in rats of the 2 and 10 mg/L arsenic exposure groups was shorter than that in the control group ( P < 0.05). The pathological examination results of Nissl staining showed that the control group had abundant Nissl bodies in hippocampal tissues of the cytoplasm with intact neuronal structures, tightly arranged cells, appearing blue purple in color and clear visible nuclei. However, the number of Nissl bodies decreased, intercellular gaps increased, disordered arrangement increased, cytoplasmic staining was lighter, and nuclear shrinkage phenomenon increased in the hippocampal tissues of rats in the 2, 10 and 50 mg/L arsenic exposure groups. The real-time fluorescence quantitative PCR detection results showed that there was a statistically significant difference in the mRNA expression levels of NLGN1, NR2A, and PSD95 in the hippocampal tissues of the four groups ( F = 13.85, 44.94, 4.63, P < 0.05). The results of Western blot analysis showed that the protein expression levels of NLGN1 and NR2A in the hippocampal tissues of rats in the 10 and 50 mg/L arsenic exposure groups were lower than those in the control group (0.65 ± 0.07, 0.69 ± 0.03 vs 1.00 ± 0.04, 0.51 ± 0.11, 0.51 ± 0.13 vs 1.00 ± 0.07, P < 0.05), and the expression level of PSD95 in the hippocampal tissues of rats in the 50 mg/L arsenic exposure group was lower than that in the control group (0.51 ± 0.09 vs 1.00 ± 0.05, P < 0.05). Conclusion:Arsenic may affect synaptic function and cause neurological dysfunction in rats by adjusting the expression levels of NLGN1, NR2A, and PSD95.
