ObjectiveTo compare the differences in color， odor， coumarin content and microbial community composition of Angelicae Dahuricae Radix（ADR） during different drying processes， and to explore the correlation between changes in microbial community composition and changes in quality indexes of ADR. MethodsThe fresh ADR was processed at three drying temperatures（50， 70， 100 ℃） by drying and steaming cutting， semi-fresh cutting and drying， fresh cutting and drying， and sulfur fumigation methods. The color values of samples were extracted by Adobe Photoshop 2022 software and subjected to principal component analysis（PCA）， electronic nose was used to identify the odor information of medicinal powders and subjected to loadings analysis， PCA， and linear discriminant analysis（LDA）， and high performance liquid chromatography（HPLC） was used to determine the contents of five coumarins（bergapten， oxypeucedanin， imperatorin， phellopterin， isoimperatorin）. The samples for microbial detection were taken from fresh dried samples， 50 ℃（dried and steamed cut， sulfur fumigated） samples， and 100 ℃（dried and steamed cut） samples when the water content was 50% and 14%， respectively. And the changes of microbial community composition during processing were determined by high-throughput sequencing method. The relationship between the changes of microbial community composition and the changes of odor， color and active component content of ADR during drying process was analyzed by Pearson correlation analysis. ResultsThe color quantification results showed that an increase in drying temperature led to the decrease of brightness value（L）， and the increases of red-green value（a） and yellow-blue value（b）， and the change of processing method had no obvious effect on the color of medicinal materials. The results of odor quantification showed that W1S， W2S， W5S， W2W and W1W sensor were sensitive to the odor changes of ADR and could be used to distinguish ADR decoction pieces from different processing methods. The results of HPLC showed that the coumarin content of ADR decreased with the increase of drying temperature and the delay of processing time， the optimal processing method was drying and steaming cutting method， and the optimal temperature was 50 ℃. High-throughput sequencing results showed that the dominant bacteria in ADR during processing were Achromobacter， Agrobacterium， Nocardioides， Mycobacterium and Enterobacter， the dominant fungi were Coprinopsis， Meyerozyma and Apiotrichum. The results of correlation analysis showed that the quality indexes of ADR were positively correlated with Agrobacterium， Mycobacterium in bacteria， Candida in fungi， and negatively correlated with Bacillus in bacteria. ConclusionThere are significant differences in the color， odor， coumarin content and microbial community composition of ADR in different drying processes， and the best drying method is drying and steaming cutting at 50 ℃. The relative abundance changes of 9 bacterial genera and 4 fungal genera are closely related to the quality formation of ADR during the drying process.

Objective: To observe the clinical efficacy and safety of Yiqi Tongluo Decoction in the intervention of early traditional Chinese medicine (TCM) syndromes after ischemic cerebrovascular disease (ICVD) intervention. Methods: From October 2020 to July 2023, a randomized, double-blind, placebo-controlled study was conducted to include 60 patients with qi deficiency, blood stasis, and phlegm obstruction syndrome after ICVD interventional therapy. They were assigned to the Yiqi Tongluo Decoction treatment group (30 cases) and the TCM placebo routine treatment control group (30 cases) according to the randomized block design. Both groups received routine standardized treatment of Western medicine, including dual antiplatelet, lipid regulation, and control of risk factors for cerebrovascular disease. The treatment group was treated with Yiqi Tongluo Decoction based on the control group. The course of treatment was 60 days and follow-up was carried out 2 and 6 months after the operation. The improvement of qi deficiency syndrome, blood stasis syndrome, phlegm syndrome score and TCM syndrome score, modified Rankin score (mRS), Barthel index (BI) score, Fatty acid-binding protein 4 (FABP4) level, incidence of transient ischemic attack (TIA) and ischemic stroke (IS) and incidence of adverse reactions, Head and neck CT angiography (CTA) or digital subtraction angiography (DSA) examination were collected. The clinical efficacy of the patients 2 months after the operation was taken as the main outcome index to preliminarily evaluate the early and long-term efficacy of Yiqi Tongluo Decoction after the ICVD intervention. The early and long-term clinical efficacy and safety of Western medicine standardized treatment combined with TCM Yiqi Tongluo Decoction on patients with qi deficiency, blood stasis and phlegm obstruction syndrome after ICVD intervention were evaluated. The safety of Yiqi Tongluo Decoction in the treatment of patients after ICVD intervention with white blood cell (WBC), C-reactive protein (CRP), fibrinogen (FIB), plasminogen time (PT), recurrence of cerebral ischaemia and restenosis in patients at 2 and 6 months after treatment were evaluated. Results: Compared to the control group, the TCM syndrome scores for qi deficiency, blood stasis and phlegm syndrome in the treatment group reduced significantly, the clinical efficacy improved significantly, the mRS score and FABP4 were reduced, and the BI score was increased. Adverse events such as cerebral ischaemia were fewer in the treatment group than in the control group, but the difference was not statistically significant; levels of CRP, WBC and PT were reduced, and levels of FIB were reduced at 6 months post-treatment, all P<0.01, and images were intuitively compared. The treatment group was superior to the control group. Conclusion Yiqi Tongluo Decoction combined with Western medicine standard treatment can improve the early clinical efficacy of ICVD patients with qi deficiency, blood stasis and phlegm obstruction syndrome after interventional surgery, improve neurological impairment and daily living ability, reduce the state of qi deficiency syndrome, blood stasis syndrome and phlegm syndrome after interventional surgery, and improve the clinical efficacy of TCM. At the same time, it can reduce the level of FABP4, the target of atherosclerosis and restenosis after interventional surgery, reduce the level of inflammation after interventional surgery in patients with ICVD, regulate coagulation function, and reduce the incidence of long-term recurrence of cerebral ischemia after interventional surgery, with good safety.

Pre-admission is a critical initiative to optimize medical service processes and alleviate the challenge of "difficult access to healthcare. "However, there is currently a lack of standardized protocols for pre-admission procedures. This study aims to systematically analyze key nodes and risk factors in pre-admission process design and propose optimization strategies, providing a foundation for policy formulation and hospital practices. By constructing a "forward-reverse" dual-process model of pre-admission and identifying risk points based on stakeholder theory (patients, hospitals, healthcare administration, and insurance), the study reveals that while pre-admission can reduce the average length of stay, improve bed turnover rates, and enhance patient satisfaction, it also presents risks such as cross-period financial settlement, challenges in insurance policy adaptability, demands for information system integration, and the need for defining medical safety boundaries. To optimize the pre-admission process and mitigate these risks, this study explores framework improvements in areas including eligibility criteria, mode selection, cost settlement, transition between pre-admission and inpatient status, and cancellation of pre-admission, offering practical guidance for public hospitals. The authors argue that pre-admission requires tripartite collaboration among hospitals, insurers, and healthcare administrations: hospitals should establish top-level design, continuously refine processes, and implement dynamic risk assessment mechanisms; insurance providers should support cross-period settlement policies; and healthcare administrations should issue guiding policies or standardized protocols. Through multi-department coordination and collaborative efforts, the optimization and innovation of pre-admission processes can be advanced, ultimately delivering more efficient and convenient healthcare experiences for patients.

Objective: To investigate the knowledge, attitudes, practices (KAP) and the situation of home blood pressure monitoring (HBPM) among hypertension patients in rural areas of Shanghai Municipality, so as to provide a basis for enhancing blood pressure management in this population. Methods: From June to October 2021, hypertension patients under management in Luodian Town and Luojing Town of rural areas of Shanghai Municipality were selected as survey subjects using a multistage random sampling method. Demographic information, KAP related to hypertension, and HBPM status were collected through questionnaire surveys. Patients were categorized into short disease duration (≤5 years), medium disease duration (6-10 years), and long disease duration (≥11 years) groups. KAP and HBPM status across different disease duration groups were analyzed statistically. Results: A total of 2 894 hypertensive patients were surveyed, including 1 317 (45.51%) males and 1 577 (54.49%) females. The median age was 69.00 (interquartile range, 10.00) years. There were 610 cases with short disease duration, accounting for 21.08%; 629 cases with medium duration, accounting for 21.73%; and 1 655 cases with long duration, accounting for 57.19%. The awareness of "hypertension control measures" was relatively high (97.89%), while awareness of "hypertension complications" was relatively low (71.70%). The adherence rate of "not perceiving difficulty in remembering to take medication on time and in correct doses" was relatively low (78.89%), and the proportion of participants who "walked ≥10 minutes per session at least once in the past 7 days" was relatively high (80.48%). A total of 1 209 cases (41.78%) engaged in HBPM, including 233 cases with short disease duration (19.27%), 252 cases with medium disease duration (20.84%), and 724 cases with long disease duration (59.88%). Compared with long disease duration hypertension patients, those with short disease duration had a alower awareness of "principles of pharmacological treatment for hypertension", a lower adherence rate of "medication should not be stopped after blood pressure control", and a lower proportion of providing their blood pressure measurement results to doctors (all P<0.017). However, they had higher proportions of alcohol consumption and daily salt intake >6 g/d (both P<0.017). Conclusions Short disease duration hypertension patients exhibit poorer performance in hypertension-related KAP and HBPM compared to long disease duration patients in rural areas of Shanghai Municipality. It is recommended to implement tailored health education based on disease duration, promote HBPM, and enhance blood pressure control rate.

ObjectiveAccording to the etiology， pathogenesis， and clinical characteristics of dry eye （DE）， this paper aims to analyze existing DE animal models to provide recommendations for building more clinically relevant DE models that integrate traditional Chinese and Western medicine. MethodsBy the retrieval and analysis of relevant literature on DE animal experiments， combined with expert consensus， an evaluation scale was created to assess relevance from the perspectives of pathogenesis， diagnostic criteria， and traditional Chinese medicine （TCM） differentiation. On the basis of data provided by the literature， the clinical relevance was evaluated for the animal models constructed in the literature. ResultsAmong the existing methods for establishing a DE animal model， benzalkonium chloride eye-drop induction showed the highest clinical relevance， demonstrating 98% alignment with Western medicine. However， current models generally showed higher relevance to Western medicine than to TCM， and there was a lack of models integrating disease with syndrome. ConclusionAs DE involves diverse causes and pathogenesis， single-factor models cannot fully simulate the complex pathology of DE. Future research should focus on building multi-mechanism DE models， exploring new etiological directions， standardizing model evaluation systems， and promoting integration of traditional Chinese and Western medicine. This will help precisely simulate the pathophysiological process of human DE and provide more valuable guidance for clinical diagnosis and treatment， ultimately enhancing patient outcomes and satisfaction.

ObjectiveTo explore the potential therapeutic targets and molecular mechanisms of menstrual blood-derived stem cells (MenSCs) transplantation combined with exercise training in promoting recovery in rats with spinal cord injury (SCI) through transcriptome sequencing analysis. MethodsFemale SD rats aged two months were selected and a SCI model was established by a hemisection at the tenth thoracic vertebra (T10). The rats were then divided into two groups: the Cell and Treadmill Training (CTMT) group, which received MenSCs transplantation and treadmill training after SCI, and the SCI group (control), with 12 rats in each group. One week after modeling, the CTMT group received a microinjection of 1×10⁵ MenSCs at the injury site, followed by two weeks of weight-supported aerobic exercise training. Spinal cord tissue from the injury site was selected for transcriptome sequencing, and mRNA expression data from both the SCI and CTMT groups were analyzed. Differential gene expression, GO (Gene Ontology) functional enrichment, KEGG (Kyoto Encyclopedia of Genes and Genomes) pathway enrichment, and protein-protein interaction (PPI) network analyses were performed. Motor function recovery was assessed using the Basso, Beattie, and Bresnahan (BBB) score, while histopathological changes at the injury site were evaluated through hematoxylin-eosin (HE) staining. Real-time fluorescent quantitative PCR and Western blotting were used to verify the expression of differentially expressed genes. ResultsTranscriptome sequencing analysis showed 247 upregulated genes and 174 downregulated genes in the CTMT group compared to the SCI group. Notably, genes such as Bdnf, Hmox1, Sd4, Mmp3, and Cd163 were significantly upregulated [|log2(FoldChange)|≥0.66, P<0.05]. KEGG pathway enrichment analysis and GO functional enrichment analysis indicated that these differentially expressed genes were mainly involved in growth and development, metabolic reactions, and immune-inflammatory processes, such as axon growth and the electron transport chain. The Bdnf gene was notably enriched in the PI3K-Akt signaling pathway. The BBB score showed that MenSCs transplantation combined with exercise training significantly improved the motor function of SCI rats. HE staining revealed that pathological changes at the injury site were significantly reduced in the treatment group. Furthermore, real-time quantitative PCR and Western blotting confirmed that brain-derived neurotrophic factor (BDNF) mRNA and protein expression levels in the CTMT group were significantly higher than those in the SCI group (P<0.001). ConclusionThe combined exercise training with MenSCs effectively promotes the recovery of motor function in SCI rats by upregulating BDNF expression, providing a novel strategy for SCI treatment.

Retinitis pigmentosa(RP)is a degenerative blinding disease characterized by the loss of the function of photoreceptor and retinal pigment epithelium. The activation of endoplasmic reticulum stress is a cellular defense regulatory mechanism, aimed at restoring the stability of endoplasmic reticulum function by self-regulation through a series of molecular signaling pathways. Rhodopsin mutation is a common cause of RP. Misfolding and retention of rhodopsin in endoplasmic reticulum and apoptosis of photoreceptor cells and retinal pigment epithelial cells induced by endoplasmic reticulum stress can lead to the occurrence and development of RP. This paper discusses endoplasmic reticulum stress and its role in the pathogenesis of RP and the role of endoplasmic reticulum stress inhibitors, traditional Chinese medicine and chemical drugs in regulating endoplasmic reticulum stress in RP treatment was summarized, in order to provide theoretical basis for endoplasmic reticulum stress in the clinical application of RP and provide new ideas for the research, prevention and treatment of RP.
