Employing bibliometric methods and adhering to principles of textual research, this study systematically investigated prescription source, formula name, composition evolution, dose evolution, origin, processing, ancient and modern applications of Xiaofengsan. Xiaofengsan, also known as Renshen Xiaofengsan and Chantui Xiaofengsan, was first recorded in the Taiping Huimin Hejijufang(hereafter referred to as Jufang) of the Southern Song dynasty. The formula composition included Schizonepetae Spica, Glycyrrhizae Radix et Rhizoma, Chuanxiong Rhizoma, Notoptery Rhizoma et Radix, Bombyx Batryticatus, Saposhnikoviae Radix, Poria, Cicadae Periostracum, Pogostemonis Herba, Ginseng Radix et Rhizoma, Magnoliae Officinalis Cortex and Citri Reticulatae Pericarpium, a total of 12 medicinal materials. In terms of the evolution of formula composition, formulas across dynasties largely aligned with those recorded in Jufang, with only minor variations in application. The results of the formula dosage research indicated that one dose of medication in Jufang corresponded to the following modern dosages:Schizonepetae Spica of 82.6 g, Glycyrrhizae Radix et Rhizoma of 82.6 g, Chuanxiong Rhizoma of 82.6 g, Notoptery Rhizoma et Radix of 82.6 g, Bombyx Batryticatus of 82.6 g, Saposhnikoviae Radix of 82.6 g, Poria of 82.6 g, Cicadae Periostracum of 82.6 g, Pogostemonis Herba of 82.6 g, Ginseng Radix et Rhizoma of 82.6 g, Magnoliae Officinalis Cortex of 20.65 g and Citri Reticulatae Pericarpium of 20.65 g, the origins of all the constituent drugs were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The results of the investigation into the decoction method indicated that the aforementioned drugs should be finely ground into powder(pass through the No.5 sieve), and 8.26 g was taken for each dose, which was taken with the clear liquid obtained by steeping tea leaves in boiling water for several minutes. This mixture was administered three times daily, 30 min after meals. The ancient functional indications of this formula mainly involved dispelling wind-heat, eliminating pathogenic factors and regulating the middle Jiao. It primarily treated all wind-heat syndromes manifesting as skin diseases, predominantly affecting the upper body, especially the head and face. The diseases involved in modern applications were mostly dermatological diseases, including urticaria, eczema, atopic dermatitis and others. In this paper, by combing the relevant ancient literature, the key information of Xiaofengsan was textual researched, in order to provide reference for the modern application and development of this formula.

ObjectiveTo address the challenges of unstructured classical Chinese expressions, nested entity relationships, and limited annotated data in famous traditional Chinese medicine(TCM) case records, this study proposes a joint relation extraction framework that integrates data augmentation and entity mapping, aiming to support the construction of TCM diagnostic knowledge graphs and clinical pattern mining. MethodsWe developed an annotation structure for entities and their relationships in TCM case texts and applied a data augmentation strategy by incorporating multiple ancient texts to expand the relation extraction dataset. A cascade binary tagging framework for relation triple extraction(CasRel) model for TCM semantics was designed, integrating a pre-trained bidirectional encoder representations from transformers(BERT) layer for classical TCM texts to enhance semantic representation, and using a head entity-relation-tail entity mapping mechanism to address entity nesting and relation overlapping issues. ResultsExperimental results showed that the CasRel model, combining data augmentation and entity mapping, outperformed the pipeline-based Bert-Radical-Lexicon(BRL)-bidirectional long short-term memory(BiLSTM)-Attention model. The overall precision, recall, and F1-score across 12 relation types reached 65.73%, 64.03%, and 64.87%, which represent improvements of 14.26%, 7.98%, and 11.21% compared to the BRL-BiLSTM-Attention model, respectively. Notably, the F1-score for tongue syndrome relations increased by 22.68%(69.32%), and the prescription-syndrome relations performed the best with the F1-score of 70.10%. ConclusionThe proposed framework significantly improves the semantic representation and complex dependencies in TCM texts, offering a reusable technical framework for structured mining of TCM case records. The constructed knowledge graph can support clinical syndrome differentiation, prescription optimization, and drug compatibility, providing a methodological reference for TCM artificial intelligence research.

ObjectiveTo investigate the mechanisms by which the combination of berberine (BBR) and baicalin (BAI) ameliorates type 2 diabetes mellitus (T2DM) due to internal accumulation of dampness-heat from the perspectives of gut microbiota and metabolomics. MethodsAntibiotics were used to induce pseudo-sterile mice. Thirty pseudo-sterile mice were randomized into a normal fecal microbiota transplantation group (n=10) and a T2DM (syndrome of internal accumulation of dampness-heat) fecal microbiota transplantation group (n=20). The mice were then administrated with suspensions of fecal microbiota from healthy volunteers and a patient with T2DM due to internal accumulation of dampness-heat by gavage, respectively. Each mouse received 200 µL suspension every other day for a total of 15 times to reshape the gut microbiota. The T2DM model mice were then assigned into a model group (n=8) and a BBR-BAI group (n=11). BBR was administrated at a dose of 200 mg·kg-1, and BAI was administrated in a ratio of BBR-BAI 10∶1 based on preliminary research findings. The administration lasted for 8 consecutive weeks. Fasting blood glucose (FBG), glycated hemoglobin (HbA1c), insulin (INS), triglycerides (TG), total cholesterol (CHOL), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), and alanine aminotransferase (ALT) levels were measured to evaluate the effects of the BBR-BAI combination on glucose and lipid metabolism and liver function in T2DM mice. Hematoxylin-eosin staining was employed to observe pathological changes in the colon tissue. The expression of claudin-1, zonula occludens-1 (ZO-1), and occludin in the colon tissue was determined by Western blot. Real-time quantitative polymerase chain reaction(Real-time PCR) was employed to assess the levels of tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6) in the colon tissue. The fecal microbiota composition and differential metabolites were analyzed by 16S rRNA sequencing and ultra-high performance liquid chromatography-quadrupole-time of flight tandem mass spectrometry (UPLC-Q-TOF-MS), respectively. ResultsThe BBR-BAI combination lowered the FBG, HbA1c, and INS levels (P<0.05, P<0.01) and alleviated insulin resistance (P<0.01) in T2DM mice. Additionally, BBR-BAI elevated the levels of ZO-1, occludin, and claudin-1 (P<0.05, P<0.01) and down-regulated the expression levels of TNF-α, IL-1β, and IL-6 in the colon (P<0.05, P<0.01). The results of 16S rRNA sequencing showed that BBR-BAI increased the relative abundance of Ligilactobacillus, Phascolarctobacterium, and Akkermansia (P<0.05), while significantly decreasing the relative abundance of Alistipes, Odoribacter, and Colidextribacter (P<0.05). UPLC-Q-TOF-MS identified 28 differential metabolites, which were primarily involved in arachidonic acid metabolism and α-linolenic acid metabolism. ConclusionBBR-BAI can ameliorate T2DM due to internal accumulation of dampness-heat by modulating the relative abundance of various bacterial genera in the gut microbiota and the expression of fecal metabolites.

Through data collection and collation combined with bibliometrics, this study conducted a series of textual research on Yanghetang, such as the name and origin, the evolution of prescription composition and modern clinical application. Yanghetang was first recorded in Bencao Yidu of WANG Ang in the Qing dynasty. In addition to Yanghetang, there were 3 bynames of Jiawei Yanghetang, Quanshengji Yanghetang and Zhenjun Yanghetang. Regarding the composition of the formula, a total of 4 versions of Yanghetang were collected. The first version is the 5 medicines version of Cervi Cornus Colla, Rehmanniae Radix Praeparata, Cinnamomi Cortex, Zingiberis Rhizoma and Ephedrae Herba in Bencao Yidu. The second version is the 7 medicines version of Waike Zhengzhi Quanshengji, changing Zingiberis Rhizoma to Zingiberis Rhizoma Praeparatum Carbonisata(ZRPC) and adding Sinapis Semen and Glycyrrhizae Radix et Rhizoma(GRR) on the basis of Bencao Yidu, and most of the Yanghetang is of this version. The third version is the 6 medicines version of Wushi Yifang Huibian, that is, on the basis of Bencao Yidu, Zingiberis Rhizoma is changed into ZRPC, and Sinapis Semen is added. The fourth version is the 6 medicines version in Yifang Jiedu, that is, on the basis of Bencao Yidu, Zingiberis Rhizoma is changed into Zingiberis Rhizoma Praeparatum, and GRR Praeparata cum Melle is added. Regarding the dose of Yanghetang, the doses of the medicines in Waike Zhengzhi Quanshengji was converted into the modern doses as follows:37.3 g of Rehmanniae Radix Praeparata, 1.87 g of Ephedrae Herba, 11.19 g of Cervi Cornus Colla, 7.46 g of Sinapis Semen, 3.73 g of Cinnamomi Cortex, 3.73 g of GRR, and 1.87 g of ZRPC. The origins of the above medicines are consistent with the 2020 edition of Chinese Pharmacopoeia. The processing specification of Rehmanniae Radix Praeparata is steaming method, ZRPC is ginger charcoal, Sinapis Semen is the fried products, and the rest of the medicines are raw products. The decoction method was verified by the decoction method in Chonglou Yuyao, which is similar in the time, and it is recommended that the above medicines should be added with 600 mL of water, decocted to 100 mL, and taken warmly 30 min after meal. For each dose, it is recommended to use 1-3 doses per day according to the doctor's advice in combination with clinical practice. The diseases involved in the ancient applications involved 42 diseases in 11 departments, including orthopedics, dermatology and gynecology, which were dominated by Yin-cold syndrome. However, the diseases involved in modern research also include 148 related diseases in 10 departments, such as orthopedics, obstetrics and gynecology, which is consistent with the ancient books. In recent years, the research hotspots of Yanghetang have focused on more than 10 fields, including osteoblasts, malignant tumors, wound healing, traditional Chinese medicine fumigation and so on, which are widely used. It is suitable for comprehensive research and development because of its rational formula composition, clear origin, processing and decoction method, and wide clinical application.

In this formula, Magnoliae Officinalis Cortex is processed according to the specifications for ginger-processed products, Glycyrrhizae Radix et Rhizoma is processed according to the specifications for stir-fried products, and other herbs are used in their raw products. The botanical sources of the herbs are consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. The above herbs are ground into a fine powder with a particle size passing through a No. 5 sieve. For each dose, take 8.26 g of the powdered formula, add 300 mL of water, along with 3 g of Zingiberis Rhizoma Recens and 3 g of Jujubae Fructus, and decoct until reduced to 140 mL. The decoction should be administered hot, with three times daily. To induce sweating, the patient should be kept warm under a quilt, and an additional dose should be prepared and taken if needed. This formula is traditionally used to relieve the exterior and resolve dampness, regulate Qi and harmonize the middle, which is mainly used to treat a series of diseases of digestive and respiratory systems. However, potential adverse reactions, including allergies, purpura and disulfiram-like reactions, should be considered during clinical use. Huoxiang Zhengqisan features a rational composition, extensive clinical application, and strong potential for further research and development.

Lianggesan was first recorded in Taiping Huimin Heji Jufang, which was composed of Rhei Radix et Rhizoma, Natrii Sulfas, Gardeniae Fructus, Forsythiae Fructus, Scutellariae Radix, Glycyrrhizae Radix et Rhizoma(GRR), Menthae Haplocalycis Herba, Lophatheri Herba and Mel. It was clinically applied to treat fire-heat syndrome in the upper and middle Jiao, and the curative effect was positive. In this study, the bibliometric method was used to conduct a detailed textual research on the formula name, medicinal composition, dosage evolution, origin and processing, functional indications and other aspects of Lianggesan. Research revealed that Lianggesan has six other names, such as Lianqiao Yinzi, Lianqiao Jiedusan, Jufang Lianggesan, Jiegu Lianggesan, Hejian Lianggesan and Qingji Lianggesan. Based on the edition of Taiping Huimin Heji Jufang, an analysis of the evolution of its formula composition revealed that the missing Chinese medicines were predominantly bamboo leaves and honey, while the added Chinese medicines were primarily supplements introduced to address changes in disease manifestations. After textual research, the dosage for one dose of Lianggesan from Taiping Huimin Heji Jufang was as follows:826 g of Rhei Radix et Rhizoma, 826 g of Natrii Sulfas, 826 g of GRR, 413 g of Gardeniae Fructus, 413 g of Menthae Haplocalycis Herba, 413 g of Scutellariae Radix, and 1652 g of Forsythiae Fructus. Decocting method was as following:Grinding the Chinese medicines into coarse powder(2-4 mm), taking 8.16 g per dose, adding 300 mL of water, along with 2 g of Lophatheri Herba and 5 g of Mel, and decocting to 140 mL. The residue was removed and taken warmly 30 min after meals. It was recommended to take it three times daily until improvement was achieved. The origins of the 9 Chinese medicines were consistent with the 2020 edition of Pharmacopoeia of the People's Republic of China. Except for GRR, which required single frying(stir-frying), the remaining medicines were all raw products. The description of the function of this formula in ancient books was summarized as purging fire and promoting bowel movements, clearing heat from the upper body and purging the lower body, and the main syndromes included facial redness, tongue swelling, red eyes, etc. In modern applications, the formula is primarily used for respiratory and digestive system diseases, including acute lung injury, chronic obstructive pulmonary disease, herpetic angina and aphthous stomatitis, covering 142 types of diseases. In summary, this paper can provide a basis for further research and development of Lianggesan through the literature review and key information combing.

Objective:By analyzing the genetic risk of triglyceride-glucose index(Tyg)and insulin resistance(IR)for cardiovascular disease(CVD), to elucidate the extent to which the contribution of Tyg to the risk of CVD development is influenced by IR genetic risk.Methods:In this study, we selected data from a cohort of elderly people in the Kunshan community, screened 7, 385 individuals with both clinical and genomic data, and calculated the polygenic risk score of insulin resistance(IRPRS)for each participant based on publicly available IR genome-wide association data, and assessed the effect of genetic risk and Tyg level on the risk of developing CVD using a multivariate Cox proportional risk model.Calculating interactions to assess the effects of genetic risk and Tyg levels on the risk of developing CVD, the effects of Tyg tertile grouping and IRPRS on the risk of developing CVD were assessed using a multivariate Cox proportional risk model, and subgroup analyses were performed for gender to assess the effects of Tyg tertile grouping and IRPRS on the risk of developing CVD by gender.Results:In the univariate Cox model, Q3 and IRPRS with the highest TYG levels were significantly associated with the risk of CVD, respectively( HR=1.59, 95% CI: 1.33-1.89; P<0.001; HR=1.61, 95% CI: 1.18-2.20; P=0.003).After adjusting for multiple confounders, the Q3 Group with the highest TYG level was still significantly associated with the risk of CVD( HR=1.28, 95% CI: 1.05-1.57; P=0.014), the Association of TYG with the risk of CVD did not change significantly( HR=1.29, 95% CI: 1.05-1.57; P=0.014).We conducted a subgroup analysis by sex and found that among older men, 13, the highest levels of TYG and IRPRS were significantly associated with CVD risk, respectively( HR=1.70, 95% CI: 1.31.2.20; P<0.001; HR=1.98, 95% CI: 1.24-3.15; P=0.004).After adding IRPRS to the model, the Association of TYG with the risk of CVD remained unchanged( HR=1.69, 95% CI: 1.31-2.19; P<0.001).After adjusting for various confounders, Tyg remained significantly associated with the risk of CVD( HR=1.39, 95% CI: 1.04-1.88; P=0.028), the results showed that TYG remained significantly associated with the risk of CVD( HR=1.41, 95% CI: 1.05-1.90; P=0.023), and the association did not decrease.No Association of IRPRS with CVD risk was found in older women. Conclusions:IRPRS and TYG are the risk factors of CVD, and diet, exercise, drugs and other external factors on TYG are the main risk factors of CVD.For individuals with high genetic factors, the risk of CVD can still be reduced by lifestyle adjustments such as diet, exercise and drug intervention.

Objective To explore the role and underlying mechanism of the transcriptional coactivator with PDZ-binding motif(TAZ)and a histone variant of acute histone H2A(H2A.Z)in the repair of hypoxia-induced lung injury.Methods A mouse model of hypoxic lung injury was established by being placed in a hypoxia chamber(simulating an altitude of 5 800 m)for 4 d.HE staining was used to observe the severity of lung injury.A hypoxia model of murine alveolar epithelial cells(murine lung epithelial-12,MLE12)was constructed by treating the cells in a hypoxia workstation(1%O2 concentration)for 24 h.Western blotting was employed to detect TAZ expression.The proliferation of alveolar epithelial cells(AECs)was evaluated by CCK-8 assay.Co-immunoprecipitation(Co-IP)assay was utilized to verify the interaction between TAZ and H2A.Z.CUT&Tag sequencing was performed to determine the effect of TAZ on the chromatin deposition of H2A.Z.Results Hypoxia significantly induced alveolar atrophy and inflammatory infiltration in mouse lung tissues(P<0.01).Hypoxia significantly up-regulated the protein level of TAZ in MLE12 cells(P<0.05).CCK-8 assay showed that knockdown of TAZ significantly reduced the proliferative capacity of AECs(P<0.01).Co-IP assay confirmed the physical interaction between TAZ and H2A.Z.CUT&Tag sequencing revealed that hypoxia promoted the deposition of H2A.Z on chromatin(31 817 peaks under normoxia,44 078 peaks under hypoxia),which was partially reversed by TAZ knockdown(37 840 peaks).Conclusion Hypoxia significantly up-regulates the expression of TAZ,which combines with H2A.Z and promotes the deposition of H2A.Z on chromatin,thus enhancing the proliferation of AECs in response to hypoxic injury.
