ObjectiveTo characterize the changes in the overall chemical profile and key index components during nine-time repeating steaming and sun-drying processing of Rhei Radix et Rhizoma， and to reveal the change law of its material basis. MethodsHigh performance liquid chromatography（HPLC） was used to analyze the changes in the overall chemical profile of Rhei Radix et Rhizoma decoction pieces， and the contents of 15 main active components such as chrysophanol-8-O-β-D-glucoside， chrysophanol and gallic acid in the process of nine-time repeating steaming and sun-drying were determined. Combined with chemometrics， the contents and quantity ratio relationships of the glycosides， aglycones and tannins during the processing of Rhei Radix et Rhizoma were analyzed， and the partial least squares-discriminant analysis（PLS-DA） and cluster analysis of the main components in different steaming times were conducted， the statistically significant differential markers were selected with the variable importance in the projection（VIP） value>1. ResultsIn the nine-time repeating steaming and sun-drying process of Rhei Radix et Rhizoma， there were certain regularity in the number and peak area of characteristic peaks and the steaming and sun-drying times， the anthraquinone glycosides and aglycones could be roughly divided into three stages， including rapid change stage， fluctuation change stage and stable stage， and the total amount of tannins showed a decreasing trend. However， the ratios between the three components mentioned above tended to stabilize after five rounds of steaming and sun-drying. The results of PLS-DA and cluster heatmap showed that the content of each component in Rhei Radix et Rhizoma fluctuated greatly during the 1-4 steaming and sun-drying processes， while the content of each component was relatively close during the 5-9 steaming and sun-drying processes. After screening， it was found that chrysophanol， emodin， chrysophanol-8-O-β-D-glucoside， rhein， physcion and emodin-8-O-β-D-glucoside could be used as the index components for distinguishing the processed products of Rhei Radix et Rhizoma with different steaming and sun-drying times. ConclusionThe changes in the properties and efficacy of Rhei Radix et Rhizoma caused by the processing of nine-time repeating steaming and sun-drying are due to the changes in the composition and ratio of various glycosides and complex tannins in this herb， which is also the key to the formation of its characteristic of "purgation with supplement". This study can provide a basis for the research on the processing mechanism of Rhei Radix et Rhizoma and the establishment of processing specifications.

ObjectiveThis study aims to analyze animal models of anxiety disorder based on the clinical characteristics of anxiety disorder in traditional Chinese and Western medicine， systematically assess the clinical compatibility， and provide suggestions for the construction of animal models with a high degree of clinical compatibility between traditional Chinese and Western medicine. MethodsRelevant literature on animal models of anxiety disorder was retrieved from global databases. Scoring scales were developed according to the etiology， pathogenesis， and diagnostic criteria of anxiety disorder in both traditional Chinese and Western medicine. The animal models of anxiety disorder in the literature were analyzed， and their clinical compatibility was systematically assessed to identify reference-worthy models. ResultsThe average clinical compatibility of existing animal models of anxiety disorder was 42.13% for traditional Chinese medicine and 50.94% for Western medicine. Among these， the chronic unpredictable mild stress （CUMS） model had the highest compatibility with both traditional Chinese and Western medicine. However， current models rarely reflect the clinical syndromes of traditional Chinese medicine in depth， and show limitations in syndrome differentiation. ConclusionThe existing animal models of anxiety disorder are mostly established using single-factor approaches， which fail to comprehensively simulate the onset process and physiopathological characteristics of anxiety disorder. These models also neglect the syndrome-based indicators emphasized in traditional Chinese medicine. In the future， the model development should incorporate the clinical characteristics of syndromes in both traditional Chinese and Western medicine， establish standardized evaluation criteria for anxiety disorder models， and utilize multifactorial approaches to enhance the representativeness of animal models in traditional Chinese medicine.

ObjectiveTo systematically review the modeling methods and analyzes the model alignment with clinical features of primary dysmenorrhea （PD） in both traditional Chinese medicine （TCM） and western medicine， providing theoretical and practical guidance for establishing the animal models of PD that better reflect the diagnostic and therapeutic characteristics of both TCM and western medicine. MethodsThe literature on PD animal models was searched against domestic and international databases such as PubMed， CNKI， and Wanfang Data. According to the diagnostic criteria of TCM and western medicine， the modeling methods in the literature were summarized， evaluated for strengths and weaknesses， and systematically assessed for clinical concordance rates to identify suitable reference models. ResultsThe available animal models of PD showed the average clinical concordance rates of 43.64% and 61.27% with the clinical features in TCM and western medicine， respectively. Commonly used modeling methods included estrogen administration， physical stimulation， and surgical intervention， with the estrogen combined with oxytocin model and the ice-water bath model being the most studied. The model of Qi stagnation and blood stasis syndrome that was established with the comprehensive stimulation method demonstrated the highest clinical concordance rate. ConclusionCurrent PD animal models primarily replicate dysmenorrhea and simulate menstruation， but they differ from human menstruation to some extent and cannot fully reflect the pathogenesis and physiological characteristics of PD. Moreover， except the cold coagulation and dampness stagnation syndrome and Qi stagnation and blood stasis syndrome， no animal models for other TCM syndromes have been reported， which limits comprehensive TCM research on this disease to a certain extent.

Retinal vascular diseases(RVD)are among the leading causes of blindness worldwide, with their prevalence showing an increasing trend year by year. Among them, age-related macular degeneration(ARMD), diabetic macular edema(DME), and retinal vein occlusion(RVO)are the most common types. Faricimab, developed by Roche's CrossMAB platform, is a novel bispecific monoclonal antibody that can simultaneously target and inhibit vascular endothelial growth factor-a(VEGF-A)and angiopoietin-2(Ang-2). The dual inhibition of these two key factors by Faricimab endows it with the potential to regulate angiogenesis and inflammatory responses more comprehensively and effectively, thus bringing new opportunities for the treatment of RVD.

Background Although current evidence suggests a link between outdoor air pollution and depressive symptoms, the effect of solid fuel use (a significant indoor air pollutant) on depressive symptoms in China's rural middle-aged and elderly population remains poorly understood. Objective To explore the association between solid fuel use for cooking and depressive symptoms among middle-aged and elderly people in rural areas of China, and to provide a basis for the prevention and control of depressive symptoms among residents in rural areas. Methods Data were obtained from the 2020 China Family Panel Studies (CFPS), depressive symptoms were assessed using 8-item Center for Epidemiologic Studies Depression Scale (CES-D), and cooking fuel type was self-reported. Subsequently, two-level binary unconditional logistic regression models were fitted to assess the impact of solid fuel use for cooking on depressive symptoms. Results A total of 7991 participants aged 45 years and older [mean age (58.52±9.18) years] were included in the study, with a mean CES-D score of 6.07±4.48 and a mean positive depressive symptoms rate of 34% (40.54% in the solid fuel group and 30.81% in the clean fuel group, χ²=74.40, P<0.001). After controlling for potential confounding covariates, rural middle-aged and elderly residents in the solid fuel group had a higher risk of reporting depressive symptoms than those in the clean fuel group (OR=1.36, 95%CI: 1.20-1.54), an association that was unaffected by participant characteristics and was positive across age and gender groups. Conclusion There is a positive association between solid fuel use for cooking and depressive symptoms in middle-aged and elderly people in rural areas of China. It is recommended that rural areas promote the upgrading of stoves through the installation of ventilation equipment or the switch from solid cooking fuel to clean fuel. This approach is directed toward reducing exposure to household air pollution, alleviating the prevalence of depression among middle-aged and elderly residents in vast rural areas, and enhancing their mental health.

Huopo Xialingtang is a famous classical formula for treating dampness and warmth， which is included in the Catalogue of Ancient Famous Classical Formulas（The First Batch）. In this paper， bibliometric methods was used to collect the literature related to Huopo Xialingtang， and 16 items of related literature were retrieved， involving five medical books， which were used to textual research on the origin， name， composition， drug dosage， preparation method， processing and main treatment symptoms of this formula. The results indicated that Huopo Xialingtang was originated from Yiyuan written by Shi Funan in the Qing dynasty， and and was later named and extended by He Lianchen. The composition of the proposed formula was consistent with the record of Yiyuan， and the origin of each Chinese materia medica was basically clear. Houpo was the dried bark and root bark of Magnolia officinalis， Zexie was the dried tubers of Alisma orientale， Kuxingren was the dried mature seeds of Prunus armeniaca， Doukou was the dried mature fruits of Amomum kravanh， the origin of Tuhuoxiang was consistent with the 2018 edition of Shanghai Standards of Processing Chinese Crud Drugs， and the origins of the remaining Chinese medicines were consistent with the 2020 edition of Chinese Pharmacopoeia. The converted dose of each Chinese medicine was 7.46 g for Agastache rugosa， 3.73 g for Magnoliae Officinalis Cortex， 8.39 g for Pinelliae Rhizoma Praeparatum cum Zingibere et Alumine， 11.19 g for Poria， 11.19 g for Armeniacae Semen Amarum， 14.92 g for Coicis Semen， 2.61 g for Amomi Fructus Rotundus， 5.60 g for Polyporus， 5.60 g for Alismatis Rhizoma， 14.92 g for Tetrapanacis Medulla. Huopo Xialingtang was initially used for the treatment of dampness and warmth at the beginning of the disease， and was later expanded to treat dampness obstruction， dampness-warming dysentery and so on， but always with the dampness-heat in the lungs and spleen as the pathogenesis. In modern times， the clinical application is more extensive， used in digestive， respiratory， endocrine， nervous system and other types of diseases， especially for chronic gastritis， stomach pain and fever. By combing the ancient literature of Huopo Xialingtang， we verified the origin of the formula and determined the key information of the prescription， which can provide literature reference for the clinical application and drug development of this formula.

AIM: To compare the efficacy of small-incision lenticule extraction(SMILE)and femtosecond assisted laser in situ keratomileusis(FS-LASIK)in the treatment of patients with myopia and astigmatism.METHODS: Retrospective analysis. A total of 100 cases(200 eyes)of patients with myopia and astigmatism treated in our hospital from December 2021 to December 2022 were collected. Among them, 50 cases(100 eyes)were divided into SMILE group and 50 cases(100 eyes)were divided into FS-LASIK group according to the treatment plans. The visual acuity and astigmatism, corneal morphology parameters, subjective visual quality scores, ocular surface indicators, postoperative complications, and quality of life were compared between the two groups before and after surgery.RESULTS: There was no significant difference in uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), astigmatism, corneal asphericity Q value, corneal surface regularity index(SRI), corneal thickness, and corneal curvature between the two groups before surgery and at 1 d, 1, and 6 mo after surgery(all P>0.05). At 1 and 6 mo after surgery, the subjective visual quality score, the quality of life score, Schirmer I test(SⅠt)and tear film break-up time(BUT)in the SMILE group were better than that in the FS-LASIK group(all P<0.05). The incidence of complications in the SMILE group was lower than that in the FS-LASIK group at 6 mo after surgery(P=0.005).CONCLUSION: Both SMILE and FS-LASIK have good clinical effects in the treatment of myopia with astigmatism, but the SMILE could alleviate ocular surface injury, reduce the risk of complications and improve the quality of lifes for patients.
