The Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines （hereinafter referred to as the Guidelines） is first specialized in the field of drug safety for oral Chinese patent medicines （OCPMs） in China. Rooted in China's healthcare context， the Guidelines address the unique usage patterns and risk characteristics of OCPMs， filling a regulatory gap in the pharmacovigilance framework specific to this category. To facilitate accurate understanding and effective implementation of the Guidelines， and to promote the standardized development of pharmacovigilance practices for OCPMs， this study offered a systematic interpretation based on its three core components. In the domain of risk monitoring and reporting， the paper analyzed the rationale for multi-source information integration and clarified the criteria for identifying key products and target populations for intensive monitoring. Regarding risk assessment， the Guidelines were examined from three dimensions of formulation components， medication behaviors， and population to address complex safety issues arising from medicinal constituents， irrational use， and individual susceptibility. In the area of risk control， the analysis focused on context-based interventions and dynamic closed-loop management strategies， exploring practical pathways to shift from passive response to proactive risk mitigation. Furthermore， this paper evaluated the applied value of the Guidelines and identified implementation challenges， such as insufficient capacity at the primary-care level and limited digital infrastructure. In response， the study proposed optimization strategies including establishing a dynamic updating mechanism， strengthening training at the grassroots level， and incorporating artificial intelligence to enhance pharmacovigilance capacity. This interpretation aims to provide actionable insights for marketing authorization holders （including manufacturers）， pharmaceutical distributors， healthcare institutions， and research organizations， ultimately supporting the establishment and refinement of a full lifecycle pharmacovigilance system for OCPMs.

ObjectiveThis paper aims to assess the effects of Wenfei Guyuan umbilical moxibustion on the quality of life and immune function in patients with chronic obstructive pulmonary disease （COPD） in stable phase. MethodsA multi-center randomized controlled trial design was employed，and the 220 cases of patients with COPD in stable phase from three grade A class-Ⅲ hospitals were included as research objects. The patients were randomly divided into the test group and control group，with each group consisting of 110 cases. Both groups received standardized treatment of western medicine，and the test group received Wenfei Guyuan umbilical moxibustion twice weekly for 13 weeks，followed by a 26-week follow-up period. Quality of life was evaluated by using the COPD assessment test （CAT），the modified COPD patient-reported outcomes （mCOPD-PRO） measure，and the modified effectiveness satisfaction questionnaire for COPD （mESQ-COPD） before treatment，four weeks， eight weeks， and 13 weeks of the treatment period，as well as 13 weeks and 26 weeks of the follow-up period. The number of acute exacerbation cases of patients in both groups was recorded during study period to evaluate the effect of Wenfei Guyuan umbilical moxibustion on acute exacerbations. 30 cases were randomly selected in both observation group and control group. Peripheral blood samples were collected before treatment and at 13 weeks of treatment. Enzyme-linked immunosorbent assay （ELISA） was used to detect the levels of immunoglobulin A （IgA），immunoglobulin G （IgG），immunoglobulin M （IgM），interleukin 10 （IL-10），interleukin 17A （IL-17A），transforming growth factor β1 （TGF-β1），and tumor necrosis factor α （TNF-α）. Flow cytometry was used to detect cluster of differentiation 4 positive （CD4⁺），cluster of differentiation 8 positive （CD8⁺），T helper 17 （Th17），and Treg levels， thereby preliminarily exploring the effect of Wenfei Guyuan umbilical moxibustion on immune function. ResultsA total of 220 patients were included，with five cases dropping out. 215 cases were finally included in the per-protocol set，including 107 in the treatment group and 108 in the control group. Baseline characteristics of the first two groups before treatment were compared between the two groups. In terms of life quality evaluation， the main effect of group differences on the CAT scores was significant （F=15.108，P<0.01）. The main effects of group differences on the physical domain （F=38.807，P<0.01），psychological domain （F=38.996，P<0.01），environmental domain （F=17.436，P<0.01），and total score of mCOPD-PRO （F=41.972，P<0.01） were significant. The main effects of group difference on clinical symptoms domain of mESQ-COPD （F=81.516，P<0.01），work-life ability domain （F=36.549，P<0.001），environmental adaptation ability domain （F=22.677，P<0.01），therapeutic effect domain （F=74.055，P<0.01），and total score of mESQ-COPD （F=73.251，P<0.01） were significant. Regarding acute exacerbations，during the entire study period，as well as the treatment period and follow-up period，the observation group showed fewer patients experiencing acute exacerbations compared to the control group，but the difference between the two groups was not statistically significant. In terms of immune indicators，after 13 weeks of treatment，the levels of IgA，IgG，and IgM in the observation group were significantly better than those in the control group （P<0.05）. The level of IL-10 was significantly higher than that in the control group （P<0.05），and the levels of IL-17A，TGF-β1，and TNF-α were significantly lower than those in the control group （P<0.05）. Compared with those in the control group，the level of CD4⁺/CD8⁺ in the observation group was significantly increased （P<0.05），while the levels of CD4⁺ and Treg were slightly increased，but the difference was not statistically significant. The levels of CD8⁺，Th17，and Th17/Treg were significantly decreased （P<0.05）. ConclusionWenfei Guyuan umbilical moxibustion can improve the quality of life， and immune function in patients with COPD in stable phase. It is worth promoting in clinical practice.

OBJECTIVE To explore the ameliorative effect and potential mechanism of vitexin on inflammation in ulcerative colitis （UC） mice. METHODS The UC mice model was established by continuous administration of 3% dextran sulfate sodium solution for 5 days. Mice with successful modeling were randomly divided into UC group， vitexin low- and high-dose groups （vitexin-L and vitexin-H groups， 40， 80 mg/kg）， mesalazine group （400 mg/kg）， and vitexin-H+recombinant Jagged canonical Notch ligand 1 （rJagged-1） group （vitexin-H+rJagged-1 group， 80 mg/kg vitexin+1 mg/kg rJagged-1）， with 12 mice in each group. Another 12 normal mice were used as the control （CK） group. Mice in each group were administered the corresponding drugs or the corresponding drugs and normal saline by gavage and intraperitoneal injection once daily for 7 consecutive days. General conditions were observed during the experiment. At 24 h after the last administration， the disease activity index （DAI） score was evaluated. Colonic histopathological morphology was observed and scored. Macrophage polarization levels in the spleen and colon tissues were measured. The protein expressions of interleukin-6 （IL-6）， IL-10， tumor necrosis factor-α （TNF-α）， transforming growth factor-β 1 （TGF-β 1 ）， Jagged-1， Notch1 and Notch intracellular domain （NICD） in colonic tissues were determined. RESULTS Compared with the UC group， the symptoms （reduced food and water intake， dull fur， etc.） and pathological changes （epithelial cell shedding， inflammatory cell infiltration， etc.） were significantly improved in the vitexin-L， vitexin-H and mesalazine groups. DAI scores， colonic histopathological scores， M1 macrophage contents in spleen tissue， M1/M2 macrophage ratios， M1 macrophage proportions in colon tissue， and protein expressions of IL-6， TNF-α， Jagged-1， Notch1 and NICD in colon tissue were significantly decreased （ P ＜0.05）. Meanwhile， the M2 macrophage contents in spleen tissue， M2 macrophage proportions in colon tissue， and protein expressions of IL-10 and TGF-β 1 in colon tissue were significantly increased （ P ＜0.05）. Moreover， the improvement effects in the vitexin-H and mesalazine groups were significantly superior to those in the vitexin-L group （ P ＜0.05）. Compared with the vitexin-H group， the above symptoms and pathological changes were aggravated， and all quantitative indicators were significantly reversed in the vitexin-H+rJagged-1 group （ P ＜0.05）. CONCLUSIONS Vitexin can ameliorate the inflammation of UC mice， which is associated with its inhibition of the Jagged-1/Notch1 pathway and regulation of macrophage polarization （inhibition of M1-type polarization and promotion of M2-type polarization）.

The anterior cingulate cortex (ACC) has recently been proposed as a key player in the representation of itch stimuli. However, to date, little is known about the contribution of specific ACC interneuron populations to itch processing. Using c-Fos immunolabeling and in vivo Ca²⁺ imaging, we reported that both histamine and chloroquine stimuli-induced acute itch caused a marked enhancement of vasoactive intestinal peptide (VIP)-expressing interneuron activity in the ACC. Behavioral data indicated that optogenetic and chemogenetic activation of these neurons reduced scratching responses related to histaminergic and non-histaminergic acute itch. Similar neural activity and modulatory role of these neurons were seen in mice with chronic itch induced by contact dermatitis. Together, this study highlights the importance of ACC VIP⁺ neurons in modulating itch-related affect and behavior, which may help us to develop novel mechanism-based strategies to treat refractory chronic itch in the clinic.

Objective To observe the clinical effect of Jiu-Wei-Yong-An granule combined with cetirizine in the treatment of damp-heat accumulation syndrome of eczema. Methods 108 eczema patients with syndrome of damp-heat accumulated in the skin, treated in the Department of Traditional Chinese Surgery in the First Affiliated Hospital of Naval Medical University from December 2021 to March 2023, were selected. They were randomly divided into an observation group and a control group, 54 cases in each. Both groups took cetirizine tablets orally for basic treatment. The observation group was given Jiu-Wei-Yong-An granules, and the control group was given placebos of the same. The clinical efficacy before and after treatment in the two groups was observed and compared, including TCM syndrome scores, eczema area and severity index （EASI）, visual analogue scale （VAS）, and adverse reactions. Results After treatment, the total effective rate of the observation group （88.9%） was higher than that of the control group （77.8%）, and the difference was statistically significant （P<0.05）. After treatment, the TCM syndrome score, EASI and VAS in the observation group were significantly lower than those in the control group （P<0.05）, and the difference was statistically significant. There was no significant difference in the total rate of adverse reactions between the two groups （P>0.05）. Conclusion The combination of Jiu-Wei-Yong-An granules and cetirizine tablets in the treatment of damp-heat eczema showed significantly better clinical outcomes in the observation group compared to the control. It effectively improved patient conditions, reduced skin lesion areas, and alleviated itching, with both safety and efficacy that merit clinical promotion.

To investigate the effect of Xuebijing injection (XBJ) on cGAS/STING pathway in alleviating sepsis-induced acute lung injury (ALI), the mouse sepsis-induced ALI model was established by cecal ligation and puncture (CLP), and the cell inflammation model was constructed by LPS stimulating RAW264.7 cells. The effects of XBJ on lung tissue injury and cGAS/STING pathway-related protein expression in septic mice were investigated by HE staining, ELISA, and Western blot. The results showed that XBJ intervention could alleviate lung tissue injury, reduce serum IL-6, TNF-α, IFN-β, IL-1-β levels, and the expression of cGAS, STING, p-TBK1, and p-IRF3 proteins in lung tissue in vivo, and reduce the mRNA level of related inflammatory factors in RAW264.7 cells and the expression of cGAS/STING pathway proteins in vitro. The results showed that XBJ could play a role in the prevention and treatment of sepsis-induced ALI by inhibiting the inflammatory response via inhibition of the activation of cGAS/STING pathway. This study provides a new molecular mechanism for the clinical prevention and treatment of sepsis-induced acute lung injury with XBJ.

Objective To evaluate the clinical efficacy of Traditional Chinese Medicine （TCM）external treatment methods in alleviating skin pruritus caused by eczema through a Meta-analysis. Methods Randomized clinical trials investigating the use of TCM external treatment methods for skin pruritus caused by eczema were searched in databases including China National Knowledge Infrastructure （CNKI）, VIP, Wanfang, Sinomed, PubMed, Embase, LILACS, and Cochrane, up to December 2024. Two reviewers independently screened and entered the statistical data, conducted bias risk assessment by the Cochrane Handbook for Systematic Reviews of Interventions, version 5.1.0, and performed Meta-analysis using RevMan 5.4.1. Results Ultimately, 14 studies involving 1 788 patients were included. Compared to the control group, TCM external treatment methods （treatment group）showed better improvement in pruritus scores （Z=11.88, P<0.000 01）, better improvement in Eczema Area and Severity Index （EASI） scores （Z=23.15, P<0.000 01）, higher overall clinical efficacy rate （Z=6.21, P<0.000 01）, better improvement in TCM symptoms （Z=5.49, P<0.000 01）, and lower clinical recurrence rate （Z=2.88, P=0.004）. Three of the included studies mentioned adverse reactions, with the treatment group showing lower adverse reactions than the control group. Conclusion The external treatment of TCM was more effective in treating skin pruritus caused by eczema compared to the control group. Given the biases and heterogeneity in the included literature, this conclusion needs to be further substantiated by more large-scale, multi-center, randomized, controlled, and double-blind studies.

The Compilation Instructions for Expert Consensus on Clinical Application of Dieda Huoxue capsules systematically expound the development methods and evidence-based basis of this consensus. In view of the weak clinical application evidence and ambiguous indications of Dieda Huoxue capsules， the Institute of Basic Research in Clinical Medicine of the China Academy of Chinese Medical Sciences and Wangjing Hospital took the lead and collaborated with 33 experts from 28 medical institutions nationwide. They strictly followed the World Health Organization （WHO） guideline-making norms and the Grading of Recommendations Assessment， Development and Evaluations （GRADE） evidence-grading system and completed the compilation through multidisciplinary cooperation. The workflow included constructing clinical questions （19 items were screened by the nominal group technique）， retrieving evidence （from Chinese and English databases and grey literature）， assessing safety （integrating drug monitoring data and clinical investigations）， and forming recommendations and consensus suggestions （3 recommendations were reached via the GRADE grid method， and 16 consensus suggestions were reached by the majority vote rule）. The results indicate that the consensus clearly states that this medicine （Dieda Huoxue capsules） is applicable to conditions like traumatic injury， blood stasis-induced pain， and sudden lumbar sprains. The recommended dose is 6 capsules each time， twice a day. Combining oral administration with external application can enhance the efficacy， and elderly patients should take the medicine at intervals. Safety monitoring suggests that it should be used with caution in people with a bleeding tendency and those with an allergic constitution. The compilation process involved three rounds of reviews by internal and external experts. Literature analysis， the Delphi method， and clinical applicability tests were employed to ensure methodological rigor. The compilation instructions comprehensively present key aspects such as project approval and registration， conflict-of-interest statements， and evidence evaluation through 12 appendices， providing methodological support for the clinical translation of the consensus. In the future， it will be continuously improved through a dynamic revision mechanism.

Objective To analyze the spatiotemporal clustering characteristics of hand-foot-mouth disease (HFMD) in Songjiang District of Shanghai from 2017 to 2022, and to provide a basis for the prevention and control of HFMD. Methods The number of reported cases of HFMD and population data in Songjiang District from 2017 to 2022 were collected. SaTScan 10.1.2 was used for spatiotemporal scanning analysis, and ArcGis 10.7 was used to visually describe the spatial distribution of HFMD. Results From 2017 to 2022, a total of 12318 cases of HFMD were reported, with an average annual reporting rate of 106.72/100 000. The incidence rate of HFMD from 2017 to 2019 was 174.19/100 000, higher than the incidence rate of HFMD from 2020 to 2022 (43.29/100 000) (P<0.01). From 2017 to 2022, there were cases reported in each month throughout the year, with the peak incidence occurring from May to October each year. The incidence rate of HFMD in each area had obvious spatial clustering. The results of spatiotemporal scanning analysis showed that the high incidence areas of HFMD were mainly distributed in Jiuting Town, Jiuliting Street, Guangfulin Street, Sijing Town, and Dongjing Town (LLR=1199.68, P<0.01). Conclusion The HFMD in Songjiang District of Shanghai shows obvious spatiotemporal clustering distribution. The clustering area is mainly distributed in the northeast of the district. Attention should be paid to high-risk areas and key populations, and targeted preventive measures should be developed.
