Sangjuyin， as a pungent and cooling agent with precise therapeutic effect， is a classic pungent formula for cooling relief of the epidermis， which is highly respected by medical practitioners. This formula is from the Wenbing Tiaobian written by WU Jutong in the Qing dynasty， on the basis of which subsequent medical practitioners have made additions and subtractions to apply it. The authors used the bibliometric method to systematically organize the medical books from the Qing dynasty and the Republic of China and modern literature to analyze the composition， concoction， decoction， efficacy， and previous and modern application of Sangjuyin. After examination， the drug base of this formula is basically clear. Armeniacae Semen Amarum is the dried mature seeds of Armeniaca vulgaris， family Rosaceae. Forsythiae Fructus is the dried fruit of Forsythia suspensa， family Mulleinaceae. Menthae Haplocalycis Herba is the dried above-ground part of Mentha haplocalyx， family Labiatae. Mori Folium is the dried leaves of Morus alba， family Moraceae. Chrysanthemi Flos is the dried head of Chrysanthemum morifolium， family Asteraceae. Platycodonis Radix is the dried root of Eryngium grandiflorum， family Eryngium. Glycyrrhizae Radix et Rhizoma is the dried root and rhizome of Glycyrrhiza uralensis of the Leguminosae family， and Phragmitis Rhizoma is the fresh or dried rhizome of Phragmites communis of the Gramineae family. It is recommended that the eight drugs be used in raw form as medicine. The dosage and method of decoction were converted into a modern single dosage of 7.46 g Armeniacae Semen Amarum， 5.60 g Forsythiae Fructus， 2.98 g Menthae Haplocalycis Herba， 9.33 g Mori Folium， 3.73 g Chrysanthemi Flos， 7.46 g Platycodonis Radix， 2.98 g Glycyrrhizae Radix et Rhizoma， and 11.19 g Phragmitis Rhizoma， with 400 mL water added， and the solution was boiled to obtain 200 mL， taken twice a day. Sangjuyin has the efficacy of dispersing wind and clearing heat， promoting lung and relieving cough， and it is used for treating the initial onset of wind-warmth and the evidence of evil spirits in the lungs and collaterals. Modern research has shown that Sangjuyin is often used in the treatment of cough， pneumonia， rhinitis， and other respiratory diseases， and the results of this study provide a reference for the later development of Sangjuyin.

The invasive brain-computer interface (BCI) is a method that involves implanting microelectrodes into brain tissue to collect neural electrical signals. The signals obtained through this method are often of high precision and relatively stable. However, the chronic fibrotic reaction resulting from long-term implantation can significantly impair the quality of the collected brain electrical signals. Therefore, ensuring the long-term stability of signal acquisition is a major challenge in the development of invasive BCI. This paper systematically reviews the formation mechanisms of fibrosis at the electrode interface, elaborating on the progression from acute inflammatory responses to the development of chronic glial scars and the formation of the extracellular matrix (ECM). It introduces the roles, advantages, and disadvantages of three anti-fibrosis strategies: material and surface optimization, drug and biological factor intervention, and integration of immune regulation and tissue engineering. This paper also evaluates their practical effects and limitations in animal and human clinical applications. Finally, it highlights the importance of establishment of standardized follow-up recording mechanisms in ensuring the long-term reliability and stability of invasive BCIs, providing references and insights for future in-depth interface optimization and clinical translation.

ObjectiveThis paper aims to systematically collect and organize ancient and modern clauses and studies containing Xieqingwan， excavate and analyze the key information of Xieqingwan， and provide a reference for facilitating the development of the classic formula Xieqingwan. MethodsThe composition， dosage， decocting methods， usage， and other key information of Xieqingwan in ancient traditional Chinese medicine books were collected and analyzed by means of literature research and metrological methods. The modern clinical application of Xieqingwan was summarized. ResultsA total of 42 pieces of effective data involving 32 ancient traditional Chinese medicine books were collected. Xieqingwan was first recorded in Xiaoer Yaozheng Zhijue. The drug origin of this formula is basically clear in the ancient traditional Chinese medicine books. The modern drug usage and decocting method were as follows： Angelicae Sinensis Radix， Gentianae Radix et Rhizoma， Chuanxiong Rhizoma， Gardenia seeds， Radix et Rhizoma Rhei， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix were grounded to fine powder， decocted with honey， and finally formed into pills with the size of a chicken head （1.5 g）. It was suggested that half a pill or one pill were taken for one dose with warm Lophatheri decoction and sugar. The indications and clinical application had developed from the recordings in Xiaoer Yaozheng Zhijue and evolved from pediatrics to ophthalmic otolaryngology， neurology， dermatology， digestion， and respiratory diseases. The main pathogenesis of these diseases is heat in the liver meridian and is treated. The effect of Xieqingwan is "clearing away heat and toxicity， removing fire and relaxing the bowels， and dispersing swelling and relieving pain". It is recommended to use the corresponding preparation methods in the 2020 Edition of Pharmacopoeia of the People's Republic of China. Modern clinical studies are centered around the clinical application of Xieqingwan， which is often modified and used in treating Tourette syndrome， herpes， febrile convulsion， sleepwalking， and insomnia. ConclusionThis paper conducts a thorough textual research of the key information of Xieqingwan， induces its historic evolution， and confirms its key information， so as to provide a reference for the future development of Xieqingwan.

Objective:To identify the trajectories of dietary choline intake in middle-aged and older population, and to analyze its longitudinal association with cognitive function.Methods:Subjects aged 55 to 79 years with at least two rounds of completed population economics, lifestyle, disease history, cognitive function, dietary assessments and physical measurements in 1997-2018 and those with at least three rounds of dietary measures in 1991-2015 were selected from the China Health and Nutrition Survey. Dietary survey was conducted using three consecutive 24-hour dietary recalls combined with a weighing inventory at the household level. Cognitive assessment was performed using part of the Telephone Interview for Cognitive Status Scale. Group-based univariate trajectory modeling was used to identify trajectory of choline intake, and three-level linear mixed-effects models or three-level logistic mixed-effects models was employed to analyze the relationship between trajectory groups and cognitive function. Subgroup analyses were conducted by gender and age at baseline.Results:Four trajectories of dietary choline intake were identified in the whole population, named as low-intake-stable group (61.0%), medium-intake-stable group (23.9%), medium-intake-slowly-declined group (11.2%), and high-intake-stable group (3.9%). Three trajectories were identified for each subgroup. Low-intake-stable group accounted for more than 60% in total population as well as each subgroup, especially in women and 55-59 years group. After adjusting for covariates, global cognitive scores were 0.54 (95% CI: 0.26-0.82), 0.77 (95% CI: 0.36-1.18), and 0.85 (95% CI: 0.21-1.48) points higher in medium-intake-stable, medium-intake- slowly-declined and high-intake-stable groups in the whole population, respectively, compared with the low-intake-stable group. The likelihoods of cognitive decline were 18.4% ( OR=0.816,95% CI: 0.709-0.939), 17.6% ( OR=0.824, 95% CI: 0.680-0.998), 24.4% ( OR=0.756, 95% CI: 0.589-0.970) and 22.4% ( OR=0.776,95% CI: 0.623-0.968) lower in medium-intake-stable group of dietary choline in the whole population, medium-intake-stable group in males, medium-intake-slightly-increased group in females and medium-intake-slowly-increased group in 55-59 years at baseline than in low-intake-stable group, respectively. Conclusions:Dietary choline intake is generally lower in the Chinese population aged 55-79 years. Long-term lower choline intake has a negative impact on cognitive function in middle-aged and older adults and may increase the risk of cognitive decline. The increment in the consumption of choline-enriched foods should be recommended.

Most cancers are currently incurable, partly due to abnormal post-translational modifications (PTMs). In this study, we initially used multiple myeloma (MM) as a working model and found that SUMOylation activating enzyme subunit 1 (SAE1) promotes the malignancy of MM. Through proteome microarray analysis, SAE1 was identified as a potential target for bioactive colcemid or its derivative colchicine. Elevated levels of SAE1 were associated with poor clinical survival and increased MM proliferation in vitro and in vivo. Additionally, SAE1 directly SUMOylated and upregulated the total protein expression of p27, leading to LLPS-mediated nuclear export of p27. Our study also demonstrated the involvement of SAE1 in other types of cancer cells, and provided the first monomer crystal structure of SAE1 and its key binding model with colchicine. Colchicine also showed promising results in the Patient-Derived Tumor Xenograft (PDX) model. Furthermore, a controlled clinical trial with 56 MM patients demonstrated the clinical efficacy of colchicine. Our findings reveal a novel mechanism by which tumor cells evade p27-induced cellular growth arrest through p27 SUMOylation-mediated nuclear export. SAE1 may serve as a promising therapeutic target, and colchicine may be a potential treatment option for multiple types of cancer in clinical settings.

Objective To investigate the genetic characteristics of the VP1 region of Coxsackievirus A10 (CVA10) in Yunnan Province. Methods Fecal samples of suspected hand, foot and mouth disease (HFMD) were subjected to real-time fluorescent quantitative PCR for detection of enterovirus CVA10. Positive samples were subjected to VP1 gene sequence amplification and Sanger sequencing. Sequence splicing was performed with DNAstar7.1 Seqman software, and nucleotide sequence and amino acid site analysis were performed using Mega 6.0 software. Results The sequencing of VP1 gene of CVA10 obtained a sequence of 894 nucleotides, encoding 298 amino acids. Compared with the original strain, there were mainly three active amino acid mutation regions, 13-33, 141-142, and 283-285. The nucleotide difference rate between the Yunnan isolates and the reference strain ranged from 16.92% to 30.90%, and the amino acid difference rate ranged from 2.58% to 4.00%. C1 and C2 group nucleotide difference was 10.58%, and the amino acid difference rate was 1.80%. The VP1 150-176 region exhibited highly conserved characteristics. Six CVA10 strains and Sichuan strain MW178898 belonged to the C1 group of the C genotype. The other 14 CVA10 strains belonged to the C2 group. Conclusion VP1 gene mutation is active and CVA10 is an important pathogen of HFMD in Yunnan. C2 genotype of CVA10 is dominant in this study, and C1 and C2 have co-circulated in Yunnan. It is necessary to strengthen monitoring and develop multivalent vaccines containing CVA10 epidemic genotype.

Objective To explore the risk factors of aspiration during hospitalization in patients with ischemic stroke (IS) and establish a predictive model. Methods Based on the case-control design, clinical materials of 316 IS patients treated in the Department of Neurology of Suzhou Ninth Hospital Affiliated to Soochow University from March 2022 to October 2023 were retrospectively collected. According to incidence of aspiration during hospitalization, the patients were divided into case group with 89 cases (aspiration occurred during hospitalization) and control group with 227 cases (no aspiration occurred during hospitalization). Univariate and multivariate Logistic regression analyses were performed in both groups to screen out the risk factors of aspiration during hospitalization in IS patients. R software was used to extract 70 % of the data from the two groups as the training set (establishing a Nomogram model), and the remaining 30 % data was used as test set. Value of predictive model was evaluated by area under the curve (AUC) of the receiver operating characteristic (ROC) curve, calibration curve, and decision curve. Results There were significant differences in the terms of age, the National Institutes of Health Stroke Scale (NIHSS) score, number of lesions, homocysteine (Hcy) level, spontaneous cough, and grading of Wada drinking water test between the case group and the control group (P < 0.05). Multivariate Logistic analysis showed that large age (OR=2.201, 95 %CI, 1.254 to 3.865), high NIHSS score (OR=4.816, 95 %CI, 1.652 to 14.041), multiple lesions (OR=2.649, 95 %CI, 1.249 to 5.613), high level of Hcy (OR=1.501, 95 %CI, 1.044 to 2.158), weakened or absent spontaneous cough (OR=3.384, 95 %CI, 1.639 to 6.987), and high grading of Wada drinking water test (OR=2.878, 95 %CI, 1.422 to 5.783) were the risk factors of aspiration during hospitalization in IS patients (P < 0.05). In the training set, the AUC of the Nomogram model for predicting aspiration during hospitalization in IS patients was 0.872 (95 %CI, 0.827 to 0.919), and was 0.859 (95 %CI, 0.807 to 0.904) in the test set. The calibration curve analysis showed that P value was 0.869 in the training set and 0.898 in the test set. The decision curve analysis for both the training set and test set showed that the Nomogram model was of good clinical applicability. Conclusion The risk of aspiration during hospitalization in IS patients is related to large age, high NIHSS score, multiple lesions, high level of Hcy, weakened or absent spontaneous cough, and high grading of Wada drinking water test. The Nomogram predictive model established on these factors can effectively evaluate the risk of aspiration during hospitalization in IS patients.

Purpose Focusing on the characteristics of for-malin fixed paraffin embedded(FFPE)samples,explored nano-magnetic bead nucleic acid extraction solutions with higher qual-ity/yield and continued to improve molecular pathology technolo-gy.Methods Alternative magnetic beads were synthesised in four major categories and 15 sub-categories and we screened to obtain high-quality/yield magnetic beads centred on FFPE samples.Simulated conventional tissues,simulated coarse needle punctures(liver),and simulated fiberoptic bronchoscopy sam-ples(lungs)were sectioned with the same number of serial slices in tubes.The nucleic acids of slices were extracted using the best magnetic beads screened in this study and common com-mercially available kits,and then perform comparison and purifi-cation quality parameters such as total amount and fragment size.The downstream applications of nucleic acids were validated by PCR and Sanger sequencing.Results Screening all homemade nanomagnetic beads centered on the DNA of FFPE samples,the total recoveries of the best performance nanomagnetic beads were obtained to be 58.5％±1.58％,and the total recoveries of five commercially available commercial magnetic beads and three do-mestic kit magnetic beads ranged from 18.68％to 40.71％.The total amount of DNA(ng)extracted from the same amount of tis-sue(serial slices),the nucleic acid yield of this study in simu-lated conventional tissues,simulated coarse needle punctures,and simulated fiberoptic bronchoscopy samples were increased by 39.49％-181.72％compared with those of the commercially a-vailable kits(P＜0.05).The total amount of extracted nucleic acid from simulated fiberoptic bronchoscopy tissue sections can be more than 100 ng for 1 slice(4 μm)and more than 400 ng for 5 slices.Conclusion The DNA purification nanomagnetic beads screened with DNA from FFPE samples have a significant enhancement comparing to the existing commercial bead proto-cols,and provide space for quality assurance,automated testing,and program expansion for clinical molecular pathology testing.

Objective:To explore the impact of CACNA1C rs58619945 genotype on the cortical thickness of attentional networks in patients with Bipolar 1 disorder type (BD-Ⅰ). Methods:From August 2013 and August 2019, a total of 155 BD-Ⅰ patients were recruited from the outpatient and inpatient Departments of the Affiliated Brain Hospital of Guangzhou Medical University, along with 82 healthy controls (HC) from the community and university. Genotype for the CACNA1C rs58619945 locus was determined for all BD-I patients and HC subjects, followed by 3.0 T magnetic resonance imaging scans to measure the cortical thickness in the alert, orienting, and executive control subnetworks. General linear models (GLMs) were used to evaluate the impact of CACNA1C rs58619945 on the cortical thickness of attentional networks. Concurrently, attentional dimension functions were assessed using repeatable battery for the assessment of neuropsychological status (RBANS) and Cambridge neuropsychological test automated battery rapid visual information processing (CANTAB RVP) test. This study was approved by the Medical Ethics Committee of the Affiliated Brain Hospital of Guangzhou Medical University(Ethics No. 2023-056). Results:Compared with the HC group, the BD-Ⅰ patients had shown reduced thickness in bilateral prefrontal cortex, bilateral posterior cingulate cortex, and bilateral superior temporal cortex( P<0.05). A significant interaction between the CACNA1C genotype and the cortical thickness(HC vs.BD) of right prefrontal cortex, right posterior parietal cortex and right superior temporal cortex was noted( P<0.05). Partial correlation analysis has demonstrated a significant correlation between CANTAB RVP and RBANS attention indices and cortical thickness in the right prefrontal cortex, right posterior cingulate cortex( P<0.05), and right superior temporal cortex predominantly among carriers of the BD-Ⅰ G allele. Conclusion:The G allele of CACNA1C rs58619945 is associated with cortical thickness of the right prefrontal cortex, right posterior cingulate cortex, and right superior temporal cortex in BD-Ⅰ, which are part of the alerting and orienting network.
