ObjectiveThis paper aims to analyze the variety characteristics and prescription patterns of marketed traditional Chinese patent medicines for treating abortion and provide references for new medicine development and clinical application. MethodsRelevant information of traditional Chinese patent medicines for treating abortion was systematically retrieved and collected. Microsoft Excel 2021 software was used to sort and statistically analyze the medicine syndrome types， quantity， market situation， and status of package inserts. Based on the Ancient and Modern Medical Case Cloud Platform （V2.3.9）， the medicine properties， flavors， meridian tropism， and medication characteristics of standardized prescriptions were analyzed. ResultsA total of 39 marketed traditional Chinese patent medicines for treating abortion in China were included. According to disease type， these medicines were categorized as therapeutic medicines for threatened abortion and recurrent spontaneous abortion. According to clinical function， they were categorized into three groups： fetus stabilization， blood nourishment， and adjunctive conditioning. They were also categorized into pre-pregnancy conditioning and post-pregnancy fetal maintenance by clinical intervention stage. Post-marketing research showed that only three products had undergone safety evaluations and one involved pharmacoeconomic research， indicating a general lack of standardized evidence-based data. Dosage forms were mainly pills and granules. Package insert analysis revealed that 15 products listed "contraindications"， while 28 included "precautions". Based on prescription inclusion and exclusion criteria， 25 products were selected for further analysis. Their therapeutic effects were mainly concentrated on "tonifying the kidney and spleen， replenishing Qi， and nourishing blood"， with core medicines including Paeoniae Radix Alba， Angelicae Sinensis Radix， and Atractylodis Macrocephalae Rhizoma. Most medicines were warm or neutral in nature， predominantly sweet and pungent in flavor， and mainly entered the spleen， liver， and kidney meridians. ConclusionTraditional Chinese patent medicines for treating abortion demonstrate clear clinical value. However， shortcomings remain， including insufficient post-marketing research， prescription homogeneity， and incomplete package inserts. Future efforts should establish a clinically value-oriented modern development pathway， strengthen safety surveillance and evidence evaluation， improve package inserts， and promote precision use to further enhance clinical value.

ObjectiveThis study aims to systematically review the marketed traditional Chinese patent medicines for treating chronic gastritis （CG） in China. By analyzing their variety characteristics and prescription patterns， it seeks to provide references for clinical syndrome differentiation-based drug selection， treatment method optimization， and the design of high-quality clinical research. MethodsInformation on marketed traditional Chinese patent medicines for treating CG was collected. Microsoft Excel software was used to collate and statistically analyze representative drugs for each pathological stage， market status， syndrome types， and other contents. The Ancient and Modern Medical Case Cloud Platform （V2.3.9） was employed to analyze the formula composition patterns of standardized prescriptions. ResultsA total of 141 marketed traditional Chinese patent medicines for treating CG in China were included. Based on the disease's pathological progression， they can be classified into drugs for non-atrophic gastritis， atrophic gastritis， and precancerous lesions. Post-marketing research reveals that relevant evaluation is only conducted on 17 drugs， of which 2 involve pharmacoeconomic studies and 14 possess standardized evidence-based evidence. The primary dosage forms were capsules， granules， and tablets. From the 100 prescriptions screened according to inclusion/exclusion criteria， the varieties indicated for the stomach collateral stasis syndrome in atrophic gastritis accounted for the highest proportion. The main efficacy distributions were clearing heat， detoxifying， and relieving pain by promoting Qi circulation. Core drugs included Glycyrrhizae Radix et Rhizome， Paeoniae Radix Alba， and Aucklandiae Radix. Medicinal properties were predominantly warm and neutral. Flavors were mainly bitter， pungent， and sweet. The drugs primarily entered the spleen and stomach meridians. Analysis of the package inserts reveals that 67 products list "contraindications"， 110 include "precautions"， and 23 explicitly state "adverse reactions". ConclusionTraditional Chinese patent medicines for treating CG hold unique value in clinical practice. However， currently there are challenges such as insufficient clarity in syndrome type descriptions within package inserts and a relative lack of high-level evidence-based medical evidence， as well as pharmacoeconomic evaluations. Future efforts should focus on addressing these shortcomings by advancing research on syndrome characteristics and medication patterns based on syndrome differentiation， systematically conducting pharmacoeconomic evaluations， strengthening the accumulation of high-level evidence-based evidence， and， on this basis， improving patient medication adherence. This will comprehensively enhance the clinical application value and scientific connotation of this category of drugs.

Results147 kinds of FDr Chinese patent medicines were included in this study. There are a total of 40 varieties of FDr Chinese patent medicines suitable for children； The distribution of dosage forms is mainly pills， tablets， and capsules. 110 prescriptions were screened， among which the proportion of Chinese patent medicines for the treatment of spleen deficiency syndrome was the highest； The top three drug use frequency were licorice， Atractylodes macrocephala， and Poria cocos； The medicinal properties are mainly warm and flat， and the medicinal taste is mostly pungent， sweet and bitter， and most of them belong to the two meridians of the spleen and stomach； The association rules analysis obtains 20 strong association pairing sets； Three drug combinations were obtained by cluster analysis. ConclusionFDr Chinese patent medicine shows unique value in clinical application， especially in the field of children. However， there are still problems such as strong professionalism in the indication expression of drug instructions， limited coverage of the medical insurance catalog， and lack of high-level evidence-based medicine and pharmacoeconomic evidence. To this end， in the future， efforts should be made to build a multi-level evidence-based evidence system， improve medication compliance， and deepen research on syndrome-based medication laws， so as to enhance the clinical application value and scientific connotation of FDr Chinese patent medicines.

ObjectiveTo study the marketed products and prescription characteristics of Chinese patent medicines for rheumatoid arthritis （RA） in China， thus providing support for clinical application and innovative research and development of Chinese patent medicines for RA. MethodsInformation on marketed Chinese patent medicines for RA treatment was collected. Preliminary data organization and statistical analysis were performed in Microsoft Excel 2021. Subsequently， the standardized prescriptions were analyzed via the Ancient and Modern Medical Case Cloud Platform （V2.3.9） across dimensions including medicinal properties， flavors， channel tropisms， usage characteristics， and formulation patterns. ResultsThis study ultimately included 311 marketed Chinese patent medicines for RA in China. Their initial market launch dates were mostly concentrated from the 1990s to the early 21st century. The National Basic Medical Insurance， Work-Related Injury Insurance， and Maternity Insurance Drug Directory included 89 Chinese patent medicines for RA. The primary dosage forms were tablets， capsules， medicated wines， and pills. After screening， 237 prescriptions were obtained， and the research on their origins was lagging. Among them， the Chinese patent medicines for treating wind-cold-dampness obstruction syndrome accounted for the highest proportion. The top three most frequently used medicinals were Angelicae Sinensis Radix， Notopterygii Rhizoma et Radix， and Saposhnikoviae Radix. Medicinal properties were primarily warm and plain， and flavors were mostly pungent， sweet， and bitter. The medicinals predominantly exhibited the liver and spleen channel tropism. Association rule analysis revealed that the herb pairs with the highest confidence were Chuanxiong-Angelicae Sinensis Radix and Myrrha-Olibanum. Cluster analysis yielded three medicinal combinations. ConclusionAlthough Chinese patent medicines for RA have application advantages， issues such as narrow syndrome coverage and insufficient innovation in dosage forms exist. Future development should focus on constructing an evidence-based system， strengthening the textual research on prescription origins and the exploration of classical famous formulas， and promoting dosage form innovation and precise medication to enhance their clinical value.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

OBJECTIVE: To investigate the short-and med-term clinical efficacy of unicompartmental knee arthroplasty(UKA)for the treatment of medial knee osteoarthritis (OA) in elderly patients with anterior cruciate ligament deficiency(ACLD). METHODS: A retrospective analysis was conducted on 31 patients aged over 75 years old with primary medial knee OA and ACLD who underwent UKA between January 2018 and December 2022. The cohort included 12 males and 19 females, aged from 75 to 91 years with an average age of (79.56±4.54) years, with 13 left knee, 16 right knee, and 2 bilateral knees. Clinical outcomes were assessed preoperatively and at final follow-up using the visual analogue scale (VAS), Hospital for Special Surgery(HSS) score, range of motion (ROM), hip-knee-ankle angle (HKA), and tibial component posterior slope angle (TCPSA). Complications such as infection, prosthesis wear, prosthesis loosening, and dislocation were also recorded. RESULTS: All 31 patients were followed up from 12 to 63 months with an average of (28.34±10.56) months. The average postoperative TCPSA was (4.83±1.31)° ranged from 2.5° to 6.8°. At the final follow-up, there was significant improvement in VAS (3.24±0.53) vs. (6.59±0.69), HSS score (85.19±4.45) vs. (64.38±5.94), ROM (118.83±5.38)° vs. (98.85±4.08)°, and HKA (176.83±5.16)° vs. (169.57±6.28)° compared to preoperative values (P<0.05). No cases of infection, prosthesis loosening, or dislocation were reported. CONCLUSION UKA provides favorable short-and mid-term outcomes for elderly patients with medial knee OA and ACLD . However, long-term clinical efficacy needs further investigation through extended follow-up.

Liquiritigenin(LG)is a flavone of pharmacological importance,however,its application potential is severely limited due to its poor water solubility.LG could be disassociated slightly in water to form phenolate anion,therefore,better solubilization effect is expected by inclusion with cationic cyclodextrins(CCDs).In this work,four kinds of CCDs modified with amino groups at the primary face were synthesized,and their solid inclusion complexes with LG were successfully prepared by preparing their saturated solutions.The formation of the solid inclusion complexes was confirmed by scanning electron microscopy(SEM)and powder X-ray diffraction(PXRD),and their supramolecular binding behavior in solution was studied using multiple techniques.A 1∶1 inclusion stoichiometry of inclusion complexation was defined using Job plot by ultraviolet-visible(UV-vis)spectroscopy,and their binding stability constants(Ks)were determined as 2862.77,3494.70,6521.85 and 9599.48 L/mol using UV-vis spectroscopic titration,far more superior to that of nativeβ-CD(Ks=236.79 L/mol).This indicated that the amino side chains on CCDs could actively participate in the inclusion complexation through anion-cation interactions,significantly strengthening the host-guest binding between CCDs and LG.The inclusion modes were further elucidated based on proton and two-dimensional rotating-frame overhauser enhancement spectroscopy(2D-ROESY)nuclear magnetic resonance(NMR)experiments and molecular docking.Water solubility of LG was dramatically promoted up to 4.9 mg/mL,which was 70-fold higher than that of native LG.This study could draw inspiration for the binding and solubilization of phenols such as flavones by design of cationic macrocyclic molecules.

Arsenic is a semi-metal,and lipid-soluble arsenic compounds are one of the widespread forms in the environment and food chain,but there is a lack of standards for lipid-soluble arsenic compounds,which is one of the bottlenecks in the current analytical detection and toxicological studies of organic arsenic.In this study,four saturated arsenic-containing hydrocarbons,AsHC 318,AsHC 332,AsHC 346,and AsHC 374(The number is relative molecular mass),were successfully synthesized in three steps by using dimethylarsinic acid,potassium iodide,sodium hydroxide,and four brominated alkanes(1-Bromotetradecane,1-bromopentadecane,1-bromohexadecane,and 1-bromooctadecane)as raw materials.The structures of these four saturated arsenic-containing hydrocarbons were characterized by proton nuclear magnetic resonance(1H NMR)spectroscopy,13C nuclear magnetic resonance(13C NMR)spectroscopy,and high-resolution mass spectrometry(HR-MS).The yields of the method were 8%-10%,and the synthesized compounds could be used in subsequent toxicity evaluation experiments to assess the toxic effects and mechanisms of action of arsenic-containing hydrocarbons.This study provided an effective method for synthesis of arsenic-containing hydrocarbons,enriching the synthesis methods of arsenic-containing hydrocarbons,and provided raw materials for the subsequent toxicological studies of arsenic-containing hydrocarbons.
