ObjectiveTo screen suitable packaging and storage conditions for small packaged Alismatis Rhizoma decoction pieces, laying the foundation for developing standardized storage, maintenance techniques and determining shelf life. MethodsUsing the accelerated stability test method, the small packaged decoction pieces of Alismatis Rhizoma were placed in polyethylene plastic bags, aluminum foil polyethylene composite bags, and cowhide coated paper bags under temperature of (40±2) ℃ and relative humidity of (75±5)% conditions, the quality testing was conducted at the end of the 0th, 1st, 2nd, 3rd, and 6th month, respectively. Using long-term stability test method, an orthogonal experiment was designed to investigate storage conditions, packaging materials, and packaging methods. At the end of the 0th, 1st, 3rd, 6th, 9th, 12th, 18th, and 24th month, the quality of small packaged Alismatis Rhizoma decoction pieces was tested under different packaging and storage conditions(including 2 packaging methods:vacuum packaging and sealed packaging, 3 storage conditions:room temperature, cool, and modified atmosphere, 3 packaging materials:cowhide coated paper bag, aluminum foil polyethylene composite bag, and polyethylene plastic bag). Then, the G1-entropy weight method combined with orthogonal experiment was used to analyze the quality changes of the decoction pieces under different packaging and storage conditions to identify optimal packaging and storage conditions. The quality testing indicators for Alismatis Rhizoma decoction pieces were expanded beyond those specified in the 2020 edition of the Pharmacopoeia of the People's Republic of China. In addition to the existing indicators(characteristics, moisture content, extractives, and the total content of 23-acetyl alisol B and 23-acetyl alisol C), new indicators including color value, water activity, total triterpenoid content, and alisol B content have been added. ResultsThe accelerated stability test results indicated that the quality of small packaged Alismatis Rhizoma decoction pieces was more stable when packaged in aluminum foil-polyethylene composite materials compared to cowhide-coated paper bags and polyethylene plastic bags. Analysis of the long-term stability test results using the G1-entropy weight method combined with orthogonal experiment revealed that storage conditions had the greatest impact on both raw and salt-processed products, followed by packaging materials, while the packaging method had the least influence. For both types of small packaged Alismatis Rhizoma decoction pieces, modified atmosphere storage demonstrated superior efficacy compared to cool storage or room temperature storage. Storage in aluminum foil-polyethylene composite bags was superior to polyethylene plastic bags or cowhide-coated paper bags. However, the stability of sealed raw products was better than vacuum-packed ones, whereas vacuum-packed salt-processed products exhibited greater stability than their sealed counterparts. ConclusionBased on the results of the quality changes of small packaged Alismatis Rhizoma decoction pieces under different storage conditions, it is recommended that the suitable storage packaging conditions for small packaged raw products are sealed packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage, and the suitable storage and packaging conditions for small packaged salt-processed products are vacuum packaging with aluminum foil polyethylene composite bags and controlled atmosphere storage.

To interpret the evidence-to-decision (EtD) framework and to illustrate its application in traditional Chinese medicine (TCM) guideline development using the example of the Pharmacovigilance Guideline of Chinese Patent Medicine, thereby providing methodological references for TCM guideline standardization. Based on the core three stages of the EtD framework (formulating the question, making an assessment of the evidence, and drawing conclusions), critical decision points and evaluation evidence within the evidence-translation process were systematically addressed, aligning with the purpose, scope, and key questions of the guideline. Qualitative research methods, such as the nominal group technique, were employed to formulate recommendations. The analysis was conducted based on the EtD framework. During question formulation, the specific characteristics and practical needs of pharmacovigilance for Chinese patent medicines were clarified, focusing on the core objective of safety assurance throughout the product lifecycle. In the evidence assessment, multi-source evidence was integrated, including policy documents, literature research, and expert consensus, completing the evidence evaluation. Finally, in recommendation-forming, dispersed research evidence and expert experience were synthesized into consensus, culminating in the guideline's completion through solicitation of opinions and peer review. The EtD framework provides a structured tool for evidence-to-decision translation in TCM guideline development, effectively enhancing the transparency and scientific rigor of the process. Therefore, it is recommended that TCM guideline development adopt the EtD framework to improve the evidence-to-decision process with TCM characteristics.

To develop the Pharmacovigilance Guidelines for Clinical Application of Chinese Patent Medicines for Mucosal Administration in response to common problems, including insufficient safety information in package inserts, amplified medication risks in special populations, and non-standard clinical practices, thus establishing a risk management system tailored to the characteristics of Chinese patent medicines for mucosal administration. An approach combining qualitative and quantitative methods was adopted. In accordance with the Drug Administration Law of the People's Republic of China (2019 revision) and the GB/T 1.1—2020 standard, a systematic search was performed in the Chinese Pharmacopoeia (2020 edition), the Catalog of Medicines Covered by Medical Insurance (2022 edition), Chinese databases [China Network of Knowledge Infrastructure (CNKI), Wanfang Data (Wanfang), and VIP journal resource integration service platform (VIP)], and international databases (Cochrane Library, PubMed, and EMbase). Guideline outlines were developed through questionnaire surveys, expert interviews, and the nominal group technique. The content of each item was formulated with full consideration of traditional Chinese medicine (TCM) incompatibility, as well as the conceptual connotations and extensions of pharmacovigilance. The results included 54 Chinese patent medicines for mucosal administration from the Chinese Pharmacopoeia (2020 edition) and 58 from the Catalog of Medicines Covered by Medical Insurance (2022 edition). Safety-related items in the corresponding package inserts were collected, and 27 relevant publications were retrieved. Thirty experts from 24 institutions were mobilized for the drafting, and opinions from 61 external experts were solicited. A pharmacovigilance framework was established, covering the full chain of "monitoring, identification, assessment, and control". Based on seven anatomical sites, including nasal, ocular, and oral mucosa, a stratified monitoring system was constructed. The guideline proposed key recommendations on improving package insert sections such as "Adverse Reactions", "Contraindications", and "Precautions", clinical procedure standardization in healthcare institutions, risk control, and dynamic pharmacovigilance. The Guideline provides evidence-based support tailored to the risk profile of Chinese patent medicines for mucosal administration, filling the current gap in international pharmacovigilance standards in this field, while offering technical support for safety management across the full life cycle of medicines for mucosal administration.

The benefit of postoperative adjuvant therapy for patients with resectable esophageal squamous cell carcinoma (ESCC) is not yet supported by high-level evidence. This review analyzes the role of adjuvant therapy by examining the discrepancy between clinical needs and guidelines, its historical evolution, recent advances in high-risk factors, and future outlooks. We provide a detailed discussion of high-risk factors used for patient selection, including lymph node positivity, and for node-negative patients, features such as tumor length, location, T stage, extent of lymph node dissection, differentiation, vascular and neural invasion, laboratory indices, and molecular markers. The goal is to inform the development of individualized precision treatment strategies for resectable ESCC.

Objective:
To analyze the school tuberculosis (TB) outbreaks and preventive treatment in Hefei from 2022 to 2024, so as to provide reference for TB prevention and control in schools.
Methods:
Data were collected on all school based TB outbreaks occurring during 2022-2024 in Hefei, defined as ≥2 epidemiologically linked TB cases within the same school during a single semester. Statistical analyses were performed using the Chi square test.
Results:
Close contacts exhibited significantly higher TB incidence (2.88%) and latent mycobacterium tuberculosis infection (LTBI) rates (13.80%) in the school TB outbreaks, compared to non close contacts (0.12% and 2.63%, respectively). Among close contacts, secondary school students showed lower TB incidence (0.48%) and LTBI prevalence (3.42%) than both primary school or younger children (0.68%, 6.95%) and college students ( 0.78% , 6.50%), with statistically significant differences ( χ 2=360.91, 6.37; 791.71, 102.03, all P <0.05). The proportion of LTBI individuals recommended for preventive therapy was higher in primary school or younger groups (98.59%) than in secondary (95.25%) or college students (86.34%) ( χ 2=25.86, P <0.01). However, among those recommended, close contacts had higher uptake (85.82%) and completion rates (87.25%) of preventive therapy than non close contacts (69.63% and 70.57%); similarly, secondary school students demonstrated higher uptake (91.21%) and completion rates (86.45%) compared to primary school or younger (88.57%, 83.87%) and college students (57.28%, 64.08%) ( χ 2=30.52, 26.72; 125.17, 38.84, all P <0.01). Subsequent TB incidence among LTBI close contacts (13.30%) and among those who did not complete preventive therapy (22.73%) were significantly higher than among non close contacts (2.80%, 2.41%), respectively ( χ 2=32.19, 13.87, both P <0.05).
Conclusions
In school TB outbreaks, close contacts face higher LTBI prevalence and subsequent TB risk than non close contacts. College students show notably low adherence to preventive therapy. It is necessary to take targeted measures to improve the compliance of preventive measures among students.

Acute-on-chronic liver failure (ACLF) is a syndrome with high mortality triggered by acute predisposing factors in patients with underlying chronic liver diseases. Clinical studies have shown that ACLF can be reversed to a certain degree, and early intervention can improve patient prognosis, whereas delayed diagnosis and treatment can lead to a significant increase in mortality. In recent years, scholars in this field have proposed the concept of “pre-acute-on-chronic liver failure (Pre-ACLF)”, which aims to improve clinical outcomes through early identification and intervention. This article systematically reviews the origin of the Pre-ACLF concept and its latest definitions in China and globally, summarizes the latest research advances in Pre-ACLF in terms of traditional clinical-laboratory parameters, high-throughput omics, and molecular biological mechanisms, and proposes the important clinical need for further unifying the definition of Pre-ACLF.

AIM: To evaluate the repeatability and accuracy of iCare IC100 tonometer in measuring intraocular pressure(IOP)by comparing the correlation and difference with Goldmann applanation tonometry(GAT)and non-contact tonometer(NCT), and to compare the correlation of the three types of IOP measurement with the central corneal thickness(CCT).METHODS: Prospective study. A total of 90 outpatients(90 eyes)in Liaoning Aier Eye Hospital from March 2019 to May 2019 were randomly selected as study subjects. All patients were measured IOP using iCare IC100, NCT, and GAT. The interclass correlation coefficient(ICC)was used to evaluate the repeatability of IOP measured 3 times consecutively using an intraocular tonometer. The correlation and consistency of iCare IC100, GAT and NCT were compared by one-way ANOVA, Pearson linear correlation analysis and Bland-Altman analysis. The linear regression analysis was used to analyze the correlation of the three tonometers with CCT.RESULTS: The mean IOP measured with iCare IC100, GAT and NCT was 19.74±6.90, 19.88±7.07 and 18.47±6.31 mmHg, respectively(F=1.180, P=0.309). The measurements of iCare IC100 with GAT, iCare IC100 with NCT and GAT with NCT were all positively correlated(r=0.930, 0.946, 0.918, all P<0.05), the Bland-Altman analysis showed that the mean differences between iCare IC100 and GAT, iCare IC100 and NCT, GAT and NCT were -0.142±2.61, 1.27±2.24, and 1.41±2.81 mmHg, respectively, with 97%(87/90), 96%(86/90), and 97%(87/90)IOP differences distributed within their 95% confidence intervals. The IOP measured with iCare IC100 and CCT, GAT and CCT and NCT and CCT were all positively correlated(r=0.426, 0.353, 0.451, all P<0.01). The linear regression equations between iCare IC100, GAT and NCT measurement and CCT were iCare IC100 IOP=-19.62+0.074×CCT; GAT IOP=-13.54+0.063×CCT; NCT IOP=-19.65+0.072×CCT; that is, for every 10 μm increase in CCT, iCare IC100 measurement increased by 0.74 mmHg, GAT measurement increased by 0.63 mmHg, and NCT measurement increased by 0.72 mmHg.CONCLUSION: The iCare IC100 tonometer has good repeatability and accuracy in measuring IOP, and the CCT has a greater impact on the measurement of iCare IC100 than the GAT and NCT.
