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.

Prostate cancer is a prevalent malignant tumor of the male genitourinary system in China, with a persistently elevated incidence rate.Given the insidious onset, propensity for metastasis in advanced stages, and poor efficacy of traditional treatments, new hormone therapies have garnered increasing attention in recent years.A number of clinical studies have demonstrated that second-generation androgen receptor inhibitors (SGARIs), including enzalutamide, apalutamide, darolutamide, and rezvilutamide, can be beneficial in different stages of advanced prostate cancer.Furthermore, their early application has been shown to delay disease progression while maintaining a controlled safety profile.At present, SGARIs have increasingly become the primary therapeutic agents for advanced prostate cancer in various stages.This article reviews the clinical research progress of SGARIs in recent years, with the aim of offering valuable clinical reference for clinicians.

Da Chaihutang， first recorded in Shanghanlun by Zhang Zhongjing of the Eastern Han dynasty， is composed of eight medicinal herbs， namely Bupleuri Radix， Scutellariae Radix， Rhei Radix et Rhizoma， Aurantii Fructus Immaturus， Paeoniae Radix Alba， Pinelliae Rhizoma， Zingiberis Rhizoma Recens， and Jujubae Fructus. It features a well-defined hierarchy of sovereign， minister， assistant， and courier ingredients. The prescription is characterized by its balanced compatibility， mutually restrained cold and warm properties， and combined use of harmonizing and purging therapeutic strategies. As a renowned classical formula indicated for harmonizing Shaoyang and purging internal heat accumulation， it is the core prescription for the treatment of Shaoyang-Yangming combined disease. A comprehensive review of modern research literature on Da Chaihutang reveals that its chemical composition is notably diverse. The core pharmacologically active material bases of its constituent single herbs have been clearly identified， including saikosaponins from Bupleuri Radix， flavonoids from Scutellariae Radix， anthraquinones from Rhei Radix et Rhizoma， flavonoids and alkaloids from Aurantii Fructus Immaturus， monoterpene glycosides from Paeoniae Radix Alba， alkaloids and organic acids from Pinelliae Rhizoma， gingerols from Zingiberis Rhizoma Recens， and polysaccharides and triterpenoid acids from Jujubae Fructus. In the compound formula， a total of 163 chemical constituents have been comprehensively identified， among which flavonoids and their glycosides constitute the most abundant component category. Flavonoids and their glycosides， monoterpene glycosides， and pentacyclic triterpenoid saponins are regarded as the core pharmacologically active substances of the whole formula. In addition， 9 potential quality markers that can comprehensively characterize the overall quality and core therapeutic efficacy of the whole formula have been screened out. Modern pharmacological studies have shown that the pharmacological effects of Da Chaihutang exhibit synergistic characteristics involving multiple components， multiple targets， and multiple pathways. Its core pharmacological activities encompass the regulation of digestive system disorders， including pancreatic protection， intervention in biliary tract diseases， and protection of gastrointestinal mucosa； intervention in hepatobiliary diseases such as non-alcoholic fatty liver disease and cholestatic liver injury； and regulation of metabolic disorders such as hypoglycemic effect， improvement of insulin resistance， and regulation of lipid metabolism. Furthermore， it also possesses multiple pharmacological activities， including intervention in atherosclerosis， regulation of immune and inflammatory responses， multi-organ protection， and anti-hepatocellular carcinoma effect. In modern clinical practice， Da Chaihutang and its modified formulas are mostly used in combination with conventional Western medical regimens. They have demonstrated notable therapeutic advantages in the treatment of digestive system diseases such as cholecystitis， acute pancreatitis， cholelithiasis， and non-alcoholic fatty liver disease， but also have shown definite curative efficacy in the management of diseases affecting multiple other systems， including cardiovascular， endocrine， dermatological， reproductive， respiratory， neurological， urinary， pediatric， and immune systems. These combined applications can effectively improve the overall clinical response rate， shorten the time to symptom relief， and reduce both the disease recurrence rate and the incidence of adverse reactions. This review systematically summarized the formula compatibility， chemical constituents， pharmacological mechanisms， and modern clinical applications of Da Chaihutang and its modified formulas， to provide a theoretical basis and practical reference for the secondary development of classic formulas， the research and development of new drugs， and the precise and safe clinical application of this classical prescription.

OBJECTIVE To provide evidence for further improving the rules governing the renewal round of national centralized drug procurement with volume-based purchasing （VBP） program for insulin.METHODS Based on publicly available policy documents， selection outcomes， and interview data， policy text analysis， descriptive statistical analysis， the Wilcoxon signed-rank test， and thematic analysis were used to compare the procurement rules and selection outcomes between the initial and renewal rounds of the national VBP programs for insulin， and to examine the mechanisms linking rule adjustments to changes in selection outcomes.RESULTS Compared with the initial round， the renewal round retained the six procurement groups and 11 bidding units， reduced the maximum valid bid price by 40%， and introduced competitive bidding selection， revival selection， and a price line for Category A products. A total of 42 products were selected in the initial round and 49 in the renewal round， including 37 that remained selected， 5 that exited， and 12 that were newly selected in the renewal round. Within the same procurement groups， the price range decreased significantly in the renewal round compared with the initial round （ P ＝0.031）， whereas the difference in average price between the two was not statistically significant （ P ＝0.063）. Domestic manufacturers were more likely to enter the A1 category， whereas multinational manufacturers were more likely to remain in categories B/C. Mechanism analysis suggested that the price line shaped the boundary of selected prices， while the classification and volume-allocation rules linked manufacturers’ bidding decisions to expected procurement volumes， potentially altering bidding incentives and corresponding to changes in the distribution of selection outcomes.CONCLUSIONS The renewal round of the insulin VBP program established an interrelated mechanism involving price boundaries， volume-based incentives， and supply constraints through the use of price lines， product classification， and contracted volume allocation. These rule adjustments corresponded to changes in the structure of selected products， price distributions， and manufacturer classifications. Future policy refinement should strengthen the coordination among reasonable price ranges， volume-based incentives， and supply performance.

This study aimed to construct an evidence map and conduct a comprehensive analysis of clinical research literature on the treatment of pulmonary fibrosis with proprietary Chinese medicines published over the past three decades, so as to systematically evaluate the effectiveness and limitations of existing evidence and provide a scientific basis for subsequent clinical practice, research directions, and policy-making. A systematic search was conducted across 7 databases in both Chinese and English from the inception of the databases to June 1, 2024. The clinical research characteristics and methodological quality of the included literature were assessed. A total of 123 pieces of literature were ultimately included, comprising 108 interventional studies, 3 observational studies, 10 secondary study, and 2 expert consensuses. These studies involved 33 kinds of proprietary Chinese medicines, with Danhong Injection being the most widely used. Most studies had a duration of 1-3 months and a sample size ranging from 50 to 100 cases, and they were often used in combination with steroids or conventional western medicine. There was a common phenomenon of off-label use of proprietary Chinese medicines. The main outcome indicators included pulmonary function, blood gas analysis, and total effective rate, with issues such as insufficient safety reporting, lack of distinctive traditional Chinese medicine(TCM) features, absence of long-term outcome indicators, and strong subjective evaluation. In terms of methodological quality assessment, randomized controlled trial(RCT) had biases in randomization and outcome indicator measurement and a risk of selective reporting. Meta-analysis lacked reporting on protocol registration, literature exclusion lists, and disclosure of conflicts of interest. Expert consensuses lacked standards in terms of rigor, scientific basis, and applicability. The quality of clinical research evidence on the treatment of pulmonary fibrosis with proprietary Chinese medicines urgently needs improvement. It is recommended that future research should pay more attention to the scientific and rigorous design to enhance the standardization and reproducibility of the research. At the same time, it should integrate TCM theories to establish an outcome indicator evaluation system suitable for the treatment of pulmonary fibrosis with proprietary Chinese medicines, so as to fully explore the potential of proprietary Chinese medicines in treating pulmonary fibrosis.

The chemical constituents were systematically separated from the roots of Berberis polyantha by various chromatographic methods, including silica gel column chromatography, HP20 column chromatography, polyamide column chromatography, reversed-phase C_(18) column chromatography, and preparative high-performance liquid chromatography. The structures of the compounds were identified by physicochemical properties and spectroscopic techniques(1D NMR, 2D NMR, UV, MS, and CD). Four phenylpropanoids were isolated from the methanol extract of the roots of B. polyantha, and they were identified as(2R)-1-(4-hydroxy-3,5-dimethoxyphenyl)-1-propanone-O-β-D-glucopyranoside(1), methyl 4-hydroxy-3,5-dimethoxybenzoate(2),(+)-syringaresinol(3), and syringaresinol-4-O-β-D-glucopyranoside(4). Compound 1 was a new compound, and other compounds were isolated from this plant for the first time. The anti-inflammatory activity of these compounds was evaluated based on the release of nitric oxide(NO) in the culture of lipopolysaccharide(LPS)-induced RAW264.7 macrophages. At a concentration of 10 μmol·L~(-1), all the four compounds inhibited the LPS-induced release of NO in RAW264.7 cells, demonstrating potential anti-inflammatory properties.

In this study， bibliometric methods were used to systematically investigate the name and origin， the evolution of prescription composition， dose evolution， origin and processing method， decoction method， ancient application， modified application， modern application and other information of Huoxiang Zhengqisan. After research， Huoxiang Zhengqisan， also known as Huoxiang Zhengqitang， was first recorded in Taiping Huimin Hejijufang. The original formula is composed of 41.3 g of Arecae Pericarpium， 41.3 g of Angelicae Dahuricae Radix， 41.3 g of Perilla frutescens（actually Perillae Folium）， 41.3 g of Poria， 82.6 g of Pinelliae Rhizoma， 82.6 g of Atractylodis Macrocephalae Rhizoma， 82.6 g of Citri Reticulatae Pericarpium（actually Citri Exocarpium Rubbum）， 82.6 g of Magnoliae Officinalis Cortex， 82.6 g of Platycodonis Radix， 123.9 g of Pogostemonis Herba， and 103.25 g of Glycyrrhizae Radix et Rhizoma. 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.

Food safety problems caused by foodborne pathogenic bacteria pose a serious threat to public health,creating an urgent need to develop testing methods and techniques with excellent performance and are simple to use and of affordable cost.Traditional testing methods,such as isolation and culture,morphological observation,biochemical identification,and serological tests,have many limitations,including complex procedures,reliance on specialized technical equipment and personnel,and long turnaround time,rendering them inadequate for meeting current and future testing demands.Therefore,it is particularly important to develop simple,rapid,and highly sensitive methods for analyzing pathogenic bacteria.The fusion of nucleic acid aptamers and nanozymes brings new ideas for the rapid testing of pathogenic bacteria.On one hand,aptamers offer specific recognition capability for target bacteria and can be combined with various nucleic acid signal amplification techniques.On the other hand,the enzyme-like catalytic activity and signal amplification effect of many nanomaterials provide a basis for highly sensitive testing.This review highlights the application potential of nanozyme?aptamer coupling systems in the field of microbial analysis by briefly summarizing the latest research progress in the use of nanozymes combined with aptamers for the detection of foodborne pathogenic bacteria.First of all,two main approaches to conjugating nanozymes with aptamers are introduced.Then,the testing mechanisms and typical applications of nanozyme?aptamer coupling systems for foodborne pathogenic bacteria are discussed.Finally,future development trends and existing challenges are disucssed from four perspectives,including specificity,high sensitivity,high throughput,and intelligent detection.This review aims to provide a useful reference for the fusion of nanozymes and aptamers and for the development of on-site rapid testing techniques for foodborne pathogens,and to encourage broader academic interest to further advance this promising research field.

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.
