Background Microparticles (MPs) are one of the main medium of inflammatory reaction with an important role in atherosclerotic progression. Studies on association of air pollution exposure and levels of peripheral blood MPs are limited among human. Objective To evaluate the effects of short-term exposure to air pollution on levels of peripheral blood MPs. Method A panel of 73 healthy adults was followed with 4 repeated follow-ups in Beijing, China, from November 2014 to January 2016. During each visit, we collected questionnaire information, fasting venous blood, urine, and exposures to fine particulate matter (PM_2.5), black carbon, nitric oxide, nitrogen dioxide, nitrogen oxide, sulfur dioxide, carbon monoxide, and ozone. We used linear mixed-effect models to analyze associations of air pollution exposure with levels of total MPs (TMPs) and MPs derived from various cells. Stratified analysis was conducted by levels of C-reactive protein (CRP) and malondialdehyde (MDA). Results The results showed significant associations between air pollution exposure and peripheral blood TMPs at 2 h-6 d prior to the follow-ups (P<0.05), while no statistical associations were found for MPs derived from different cell types. Significant increases in TMPs of 7.8% (95%CI: 0.7%, 15.3%) and 14.3% (95%CI: 2.8%, 27.2%) were observed with each interquartile range (IQR) increase in PM_2.5 (IQR=64.9 μg·m⁻³) at prior 18 h and NO (IQR=40.5 μg·m⁻³) at prior 48 h. Among participants with low levels of CRP and MDA, significantly positive associations were observed between air pollution exposure and levels of TMPs (P<0.05). Conclusion Short-term exposure to air pollution is significantly associated with increased levels of circulating MPs in healthy adults, and in people with lower systemic inflammation, peripheral blood MPs levels are more easily affected after exposure to air pollutants.

Puerariae Lobatae Radix and Puerariae Thomsonii Radix are the dried roots of Pueraria lobata and Pueraria thomsonii of the Leguminosae family， respectively. Since their separate inclusion in the 2005 edition of Pharmacopoeia of the People's Republic of China， the two herbs have been individually recorded. Although they share the same functions and indications， the required content of puerarin differs by a factor of up to eightfold between them. The current quality standard relies solely on a single indicator， puerarin， which fails to reflect the correlation between chemical constituents and core therapeutic effects. This has resulted in prominent issues of mixed use in clinical practice and production， thereby constraining the high-quality development of the industry. Modern research has demonstrated that Puerariae Lobatae Radix contains a comprehensive range and higher content of isoflavonoid constituents， while Puerariae Thomsonii Radix is rich in starch and polysaccharides. Puerariae Lobatae Radix exhibits stronger effects in antipyresis， cardiovascular and cerebrovascular protection， and central analgesia， while Puerariae Thomsonii Radix demonstrates greater advantages in anti-inflammation， hypoglycemia， and peripheral analgesia. Based on this， the chemical material bases of Puerariae Lobatae Radix and Puerariae Thomsonii Radix at both the macromolecule and micromolecule levels were systematically reviewed and compared. The pharmacodynamic material bases and mechanisms of action underlying their three core therapeutic effects， namely "relieving exterior syndrome and clearing heat"， "promoting fluid production to quench thirst"， and "dredging channels and activating collaterals"， were summarized. The most highly correlated common metabolic pathway shared by both herbs for these three therapeutic effects is the arachidonic acid metabolic pathway， and their common core target is prostaglandin-endoperoxide synthase 2 （PTGS2）. This review provided clinical application recommendations based on the therapeutic differences between the two herbs， elucidated the scientific connotation of their "same origin but different effects"， and， grounded in the quality marker （Q-Marker）， proposed the concept of efficacy-related Q-Marker based on "substance-efficacy-syndrome" association， as well as a novel strategy for efficacy-oriented quality evaluation. Preliminary screening of quality markers associated with different therapeutic effects was also conducted. This study aims to provide critical scientific evidence for the precise clinical application of Puerariae Lobatae Radix and Puerariae Thomsonii Radix， the improvement of quality standards， and the high-quality development of the industry.

Objective:To examine the validity and reliability of the DSM-5 Social Anxiety Disorder Severity Scale(SAD-D)in a Chinese adult population.Methods:The Chinese version of the DSM-5 Social Anxiety Disor-der Severity Scale was administered via online data collection platform Credamo to 300 adults(Sample 1,for item analysis,exploratory factor analysis and item selection of brief version of SAD-D)and 528 adults(Sample 2,for confirmatory factor analysis,criterion validity test,measurement invariance analysis and internal consistency reliabil-ity analysis for both SAD-D and its brief version).Criterion validity was tested with the Social Phobia Scale(SPIN)and Personal Report of Confidence as a Speaker(PRCS).A brief version of the scale was developed by u-sing the Ant Colony Optimization(ACO).A retest was conducted with 152 participants from Sample 2 after three weeks.Results:Exploratory factor analysis indicated that the SAD-D was a unidimensional scale with factor load-ings ranging from 0.49 to 0.82,and the results of the confirmatory factor analysis also supported the unidimension-al structure(x2/df=3.49,RMSEA=0.069,CFI=0.971,TLI=0.962,SRMR=0.028).The scores of Chinese version of the SAD-D were positively correlated with the SPIN scores(ICC=0.70,P＜0.001)and PRCS scores(ICC=0.73,P＜0.001).The Cronbach'α of the scale was 0.92,and the retest reliability was 0.85.The scale dem-onstrated cross-gender measurement invariance(△CFI＜0.01,△RMSEA＜0.01).The brief version of the SAD-D was selected as items 2,5,and 6,and its Cronbach'α coefficient was 0.86.Conclusion:The Chinese version of the SAD-D has satisfactoryvalidity andreliability,making it suitable for the assessment of social anxiety symptoms with Chinese adults.

Objective:To observe the effects of exercise training on the memory ability of rats with vascular cognitive im-pairment(VCI)and to explore the possible mechanisms of action.Method:Rat models of VCI were constructed by permanently ligating bilateral common carotid arteries,and were randomly divided into sham-operated groups(Sham,n=8),exercise-training groups(VCI+Ex,n=8),and control groups(VCI,n=8)according to the randomized numerical table method.The exercise training group started moderate-intensity aerobic exercise training on a small animal treadmill at 48 hours postoperatively,and the intensity of the exercise was increased day by day(5m/min—11m/min)in the first week,and was per-formed at a constant speed of 11m/min for 30 min per day,5 days per week in the second to fourth weeks.Rats in the sham-operated group and the control group were placed in the small animal treadmill at the same time points,but not turned on,for 30 min per day,5 days per week for 4 weeks.For the rest of the time,rats in each group were put back into the rearing cages and were free to eat,drink and move around.After completing the above experiments,the memory ability of rats in each group was evaluated by Novel Object Recognition(NOR)and Y-maze experiments;then the rats were euthanized by overdose anesthesia,and the hip-pocampal tissues were isolated and extracted from the brain.The distribution of N-methyl-d-aspartate receptor(NMDAR)and α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor(AMPAR)in the hippocampal re-gion was observed by immunofluorescence staining,and the expression levels of PlexinA4 and neuropilin-2 in the hippocampal region were detected by Western Blot.Result:In the Y-maze experiment,rats in the VCI+Ex group explored the novel arm more frequently than the VCI group,as well as explored for a longer period of time than the VCI group,with significant differences(P<0.05,P<0.001);in the NOR experiment,the cognitive index of novelty of rats in the VCI+Ex group was significantly higher than that of rats in the VCI group,and the difference was significant(P<0.001).Immunoflu-orescence results showed that compared with the VCI group,the expression levels of NMDAR,PlexinA4,and neuropilin-2 in the hippocampal region of the VCI+Ex group were significantly higher(P<0.01,P<0.05,P<0.05,respectively),while there was a tendency for the expression of AMPAR and the ratio of NMDAR/AM-PAR to be elevated.Western Blot results showed that PlexinA4 expression in the hippocampus of VCI+Ex rats was higher than that of the VCI group,and the results were significantly different(P<0.05).Conclusion:Exercise training can improve the memory ability of VCI rats,and the possible mechanism is to promote the expression of NMDAR,PlexinA4 and neuropilin-2 in the hippocampus,which in turn enhances the synaptic plasticity in the hippocampus.

Bipolar disorder in children, a serious mental illness, often leads to significant functional impairment. Bipolar disorder onset in children is rare and is difficult to diagnose correctly due to the atypical clinical manifestations. Risperidone, as a second-generation antipsychotic, shows satisfied efficacy in children with bipolar disorder with dual effects on mood stabilization and psychotic symptom control. However, the long-term efficacy and safety of risperidone for the treatment of children with bipolar disorder remains unknown. This paper reports a 5-year-old child with bipolar disorder who was treated with low-dose risperidone and followed up for 4 years. The child showed significant emotional stabilization and behavioral improvement at the beginning of treatment. No serious side effects occurred during long-term follow-up. This paper detailly describes the clinical manifestations and diagnostic process of bipolar disorder onset in children in aspects of detailed clinical observation and evaluation. It summarizes the efficacy and safety of risperidone in the treatment of pediatric bipolar disorder to provide valuable experience for clinicians.

ObjectiveTo investigate the anti-Alzheimer's disease （AD） effect of Dipsacus asper（DA） in the Caenorhabditis elegans model， and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α （PPARα）/transcription factor EB （TFEB） pathway. MethodsFirst， transgenic AD C. elegans individuals were assigned into the blank control， model， positive control （WY14643， 20 µmol·L^-1）， and low-， medium-， and high-dose （100， 200， and 400 mg·L^-1， respectively） DA groups. The amyloid β-42 （Aβ₄₂） formation in the muscle cells， the paralysis time， and the deposition of amyloid β-protein （Aβ） in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ， LC3I， LAMP2， and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα， and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB， Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain （LBD）. ResultsCompared with the model group， the positive control group and 200 and 400 mg·L^-1 DA groups showed prolonged paralysis time （P<0.05）， and all the treatment groups showed decreased Aβ deposition in the head （P<0.01）. DA within the concentration range of 50-500 mg·L^-1 did not affect the viability of BV2 cells. In addition， DA enhanced the autophagy flux （P<0.05）， up-regulated the mRNA levels of beclin1， Atg5， LAMP2， and CLN2 （P<0.05， P<0.01）， promoted the nuclear translocation of TFEB （P<0.05）， increased LAMP2 expression and autophagy flux （P<0.05， P<0.01）， and enhanced the transcriptional activities of PPARα and TFEB （P<0.01）. The positive control group and 200 and 400 mg·L^-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus （P<0.01）. UPLC-MS detected nine known compounds of DA， from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

Objective: To investigate the precise detection methods for weak partial D type 15 and evaluate their implications for blood transfusion safety, along with the development of corresponding strategies. Methods: A combination of serological methods, including the microplate method, indirect antiglobulin tube method, and microcolumn gel card method, was employed to identify RhD-negative and RhD variant samples. RhD-negative samples were screened for the presence of RHD genes using whole-blood direct PCR amplification. Subsequently, RhD variant samples and RhD-negative samples containing RHD genes underwent full-coding-region sequencing of the RHD gene to confirm their genotypes. The genotyping results were further correlated with the serological test findings for comprehensive analysis. Results: Among 615 549 first-time healthy blood donors, 3 401 samples with an RhD-negative phenotype and 156 samples with RhD variant were identified. Of the 3 401 RhD-negative samples, 1 054 were found to harbor RHD genes. Gene sequencing analysis of the 156 RhD variants and the 1 054 serological negative samples revealed that 89 samples contained the RHD 15 (c. 845G>A) allele. Conclusion: The integration of serological testing methods and genotyping technologies for the precise determination of RhD blood type plays a critical role in ensuring the safety and compatibility of blood transfusions.

Objective To analyze the pattern of group medication in Parkinson's disease cognitive disorders based on data mining.Methods The famous TCM experience and effective clinical treatment of cognitive impairment in the treatment of Parkinson's disease were retrieved in databases of CNKI,Wanfang and Weipu,from the founding of the databases to August 2024.Medication rules were analyzed.Results A total of 60 Chinese prescriptions were included,including 120 traditional Chinese medicines.High-frequency drugs for the treatment of cognitive impairment in Parkinson's disease included Radix Rehmanniae Praeparata,Radix Paeoniae Alba,Rhizoma Gastrodiae Praeparata,Fructus Lycii,Herba Cistanches,Acorus Calamus and others.The flavour of the medicine were mainly sweet,bitter and pungent,the nature of the medicine was mainly warm,cold and calm and the meridians of the medicine were mainly liver,kidney and heart.Radix Rehmanniae Praeparata-Comu Cervi Pantotrichum,Rhizoma Gastrodiae Praeparata-Hooker's Tree,Radix Rehmanniae Praeparata-Cistanches are the commonly used pairs;Lycium barbarum-Cornus officinalis-Radix Rehmanniae Praeparata,Radix Rehmanniae Praeparata-Radix Angelicae Sinensis-Radix Paeoniae Alba were commonly used combination.Cluster analysis yielded 5 broad categories.Conclusion The primary pharmacological agents employed in traditional Chinese medicine to address cognitive impairment associated with Parkinson's disease emphasize the replenishment of essence and nourishing the marrow.These agents are complemented by nootropic substances that facilitate bodily openness,promote liver health,alleviate wind,resolve phlegm,and invigorate blood circulation and meridian pathways,worth of clinical promotion and application.
