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.

OBJECTIVE To compare the anti-hepatitis mechanisms of Abrus pulchellus subsp. cantoniensis (Hance) Verdc. (AC) and Abrus pulchellus subsp. mollis(Hance) Verdc. (AM). METHODS SD rats were randomly divided into blank group, AC- treated group, and AM-treated group, with each group consisting of 10 rats. The rats’ orbital venous blood was collected at 5, 15, 30 minutes, and 1, 1.5, 2, 4, 6, 8, 12 hours after gavage administration of 24 g/kg of the corresponding drug (calculated by crude drug) or water, respectively. Ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry technology was utilized to identify the prototype components present in the serum. The network pharmacology method was adopted to predict the anti-hepatitis active components, key targets, and signaling pathways of AC and AM. Additionally, molecular docking technology was utilized to verify the binding activity of the core active components with key targets. RESULTS A total of 35 prototype components migrating to the blood of AC and AM were identified in the serum of administered rats, among which 24 were common components. The active components in AC, such as acetylanguidine, physcion, soyasaponin A3 and soyasaponin Ⅰ, as well as those in AM, including vicenin 3, acetylanguidine,soyasaponin Ⅰ and schaftoside, all acted on key targets such as steroid receptor coactivator, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit alpha, epidermal growth factor receptor (EGFR), and protein kinase B1(Akt1). These components modulated pathways in cancer, EGFR tyrosine kinase inhibitor resistance, and the phosphoinositide 3-kinase (PI3K) -Akt pathway, thereby exerting anti-hepatitis effects. Furthermore, the binding energies between these active components and their key targets were all less than -5 kJ/mol. CONCLUSIONS There are differences in the active components of AC and AM against hepatitis, but their mechanisms of action are similar. Both may exert their anti-hepatitis effects through pathways in cancer, EGFR tyrosine kinase inhibitor resistance, and the PI3K-Akt pathway.

Diabetic cardiomyopathy (DCM) is a medical condition characterized by cardiac remodeling and dysfunction in individuals with diabetes mellitus. Sarcoplasmic reticulum (SR) and mitochondrial Ca2+ overload in cardiomyocytes have been recognized as biological hallmarks in DCM; however, the specific factors underlying these abnormalities remain largely unknown. In this study, we aimed to investigate the role of a cardiac-specific long noncoding RNA, D830005E20Rik (Trdn-as), in DCM. Our results revealed the remarkably upregulation of Trdn-as in the hearts of the DCM mice and cardiomyocytes treated with high glucose (HG). Knocking down Trdn-as in cardiac tissues significantly improved cardiac dysfunction and remodeling in the DCM mice. Conversely, Trdn-as overexpression resulted in cardiac damage resembling that observed in the DCM mice. At the cellular level, Trdn-as induced Ca2+ overload in the SR and mitochondria, leading to mitochondrial dysfunction. RNA-seq and bioinformatics analyses identified calsequestrin 2 (Casq2), a primary calcium-binding protein in the junctional SR, as a potential target of Trdn-as. Further investigations revealed that Trdn-as facilitated the recruitment of METTL14 to the Casq2 mRNA, thereby enhancing the m6A modification of Casq2. This modification increased the stability of Casq2 mRNA and subsequently led to increased protein expression. When Casq2 was knocked down, the promoting effects of Trdn-as on Ca2+ overload and mitochondrial damage were mitigated. These findings provide valuable insights into the pathogenesis of DCM and suggest Trdn-as as a potential therapeutic target for this condition.

ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis (ONFH, syndrome of liver and kidney deficiency) and its influences on bone metabolism indexes: N-terminal propeptide (PINP) and β-collagen degradation product (β-CTX). MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method, with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally, while the control group received Xianlinggubao Capsules orally, with a treatment cycle of 6 months. The visual analogue scale (VAS) score, Harris score, Association Research Circulation Osseous (ARCO) staging, imaging changes, quantitative scores of TCM symptoms, and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% (26/31), which was higher than that (68.75%, 22/32) in the control group (Z=-2.096, P<0.05). After treatment, the single and total scores of TCM symptoms, VAS score, and β-CTX level decreased in the two groups (P<0.05). Moreover, the decreases in the scores of hip pain, lower limb mobility, soreness of waist and knees, and lower limb flaccidity, total score of TCM symptoms, VAS score, and β-CTX level in the experimental were larger than those in the control group (P<0.05). After treatment, the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment (P<0.05), and the increases were more obvious in the experimental group than in the control group (P<0.05). No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH, increase PINP, and decrease β-CTX. No obvious side effect appears during the clinical observation period, which shows that Bushen Huoxue prescription has good safety.

Objective To investigate the role of macrophages in the process of fine particulate matter (PM2.5)exposure induced damage to pulmonary blood-air barrier.Methods Eighteen male BALB/C mice (aged of 10 weeks,weighing 24~27 g)were randomly divided into control group and low-and high-dose PM2.5 exposure groups (receiving 1 .8 and 16.2 mg/kg,respectively),with 6 mice in each group.The control group received tracheal instillations of normal saline on days 1,4,and 7,whereas the exposure groups were administered corresponding dose of PM2.5 exposure at the same time points.In 24 h after last exposure,pathological changes in the lung tissues were observed,and the contents of total protein (TP ),lactate dehydrogenase (LDH ),and alkaline phosphatase (AKP ) in bronchoalveolar lavage fluid (BALF ),and F4/80 protein level in lung tissue were measured to evaluate the blood-air barrier damage and macrophage infiltration within the lung tissues.Additionally,an in vitro model of the blood-air barrier was established using A549 alveolar epithelial cells and EA.hy926 vascular endothelial cells.In combination with a THP-1 macrophage model,the supernatant PM2.5 supernatant,macrophage supernatant,and PM2.5-macrophage supernatant were incubated with the barrier model for 24 h,respectively.Transmembrane electrical resistance (TEER),sodium fluorescein permeability of the barrier model,and LDH release from the barrier cells were measured to ascertain the extent of macrophage-mediated enhancement in barrier damage induced by PM2.5 exposure.Furthermore,the expression of inflammatory cytokines,such as TNF-α,IL-1β,IL-6,and IL-8 in the macrophages after PM2.5 exposure was analyzed with quantitative real-time PCR (qPCR)and enzyme-linked immunosorbent assay (ELISA).Results PM2.5 exposure induced lung tissue damage in mice in a dose-dependent manner,significantly elevated the contents of TP,LDH and AKP in the BALF and caused marked infiltration of macrophages into the lung tissue,especially the high-dose exposure when compared with the mice from the control group (P<0.01 ).In vitro barrier model exposure experiments showed that in comparison with the treatment of 150 and 300 μg/mL PM2.5 and macrophage supernatant,the same doses of PM2.5-macrophage supernatant resulted in notably decreased TEER and significantly enhanced permeability in the barrier model (P<0.01 ),and markedly increased LDH release from epithelial and endothelial barrier cells (P<0.01 ).Additionally,the exposure of 150 and 300μg/mL PM2.5 led to a significant up-regulation of TNF-α,IL-1β,IL-6,and IL-8 in the macrophages (P<0.01 ).Conclusion Macrophages deteriorate PM2.5-induced functional impairment of the pulmonary blood-air barrier.

Objective:To explore the effect of Jian-Pi-Zhi-Dong decoction on autonomous activity and dopamine (dopamine, DA) synaptic vesicle protein expression in the striatum of Tourette syndrome (TS) model rats.Methods:The 4-week-old male SD rats were used to establish the TS model by intraperitoneal injection of N-aminodipropionate. Thirty successfully modeled rats were randomly divided into model group, Chinese medicine group, and tiberide group according to random number table method, with 10 rats in each group. And another 10 rats with matched body mass were selected as the control group. Rats in Chinese medicine group were given Jian-Pi-Zhi-Dong decoction solution (1.6 g/100 g) and the rats in tiapride group were given sulfate tiapride suspension (2.1 mg/100 g), while rats in control group and model group were given an equal volume of 0.9% sodium chloride solution, once a day for 4 weeks.The number of autonomous activities in rats was determined by autonomous activity programmer. ELISA was used to detect the level of DA in the striatum of rats and the expression of dopamine transporter (DAT).Vesicular monoamine transporter-2 (VMAT2) and α-synuclein (α-syn) were measured by Western blot.SPSS 25.0 software was used for data analysis. Multiple group comparisons were performed using one-way ANOVA, non-parametric test and repeated measures ANOVA.Results:Comparing the number of autonomous activities among the 4 groups, the interaction effect between time and group was significant ( F=184.354, P<0.001). At the 1-4 weeks of gavaging, the numbers of autonomic activities in the model group were more than those in the control group (all P<0.05).While the numbers of autonomic activities in Chinese medicine group and tiapride group were less than those in the model group (all P<0.05). Moreover, the numbers of autonomic activities in Chinese medicine group and tiapride group from 1 to 4 weeks were less than those after model making (all P<0.05). The Western blot results showed significant differences in the relative expression of α-syn ( H=29.098), DAT ( F=54.632) and VMAT2 ( H=18.982) among the 4 groups (all P<0.001). The expression levels of α-syn protein in Chinese medicine group and tiapride group were both lower than that in the model group (0.39(0.36, 0.51), 0.39(0.36, 0.50), 0.62(0.50, 0.70)) (both P<0.05). The expression level of DAT protein in Chinese medicine group was higher than that in the model group and lower than that in tiapride group ((0.37±0.06), (0.26±0.07), (0.49±0.09)) (both P<0.05). And the expression level of VMAT2 protein in Chinese medicine group had no significant difference compared with that in the model group ( P>0.05).The ELISA results showed significant differences in DA content of striatum among the 4 groups ( F=75.370, P<0.001). The level of DA in the model group was higher than that in the control group ((7.65±0.72) ng/L, (3.71±0.59) ng/L, P<0.05). The levels of DA in Chinese medicine group ((3.92±0.81) ng/L) and tiapride group ((4.40±0.53) ng/L) were lower than that in the model group (both P<0.05), and the difference between Chinese medicine group and tiapride group was not significant ( P>0.05). Conclusion:Jian-Pi-Zhi-Dong decoction can relieve the tic symptoms of the model rats with TS, and its mechanism may be related to inhibiting the excessive release of α-syn, improving the expression of DAT and VMAT2, improving the DA synaptic vesicle circulation, and reducing the DA content in the synaptic space of the brain.

This paper reported the genetic analysis of a pedigree in which three affected fetuses with short limbs were revealed by first-trimester ultrasonography in three consecutive pregnancies. Tissues of the second aborted fetus were collected and analyzed by chromosome karyotype analysis and whole exome sequencing. The results indicated compound heterozygous mutations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene. Real-time fluorescence quantitative polymerase chain reaction and Sanger sequencing further confirmed that the two variants were inherited from the father and the mother with normal phenotypes, respectively. EX64-EX83 Del was a likely pathogenic variant and c.8190G>T was a variant of uncertain significance. Based on the above results and the medical history, it was highly suspected that the fetus had autosomal recessive short rib polydactyly syndrome type Ⅲ caused by compound heterozygous variants. Real-time fluorescent quantitative polymerase chain reaction and Sanger sequencing results of the third aborted fetus were consistent with the second fetus. Given the same phenotypes of fetuses in the second and third pregnancy, it was strongly suggested that the heterozygous variations of EX64-EX83 Del and c.8190G>T in the DYNC2H1 gene were the pathogenic variants in this pedigree.

【Objective】 To perform quantitative analysis on the sample provincial laws and regulations for voluntary blood donation, and provide reference for further revision of laws and regulations. 【Methods】 31 study samples were current provincial laws and regulations for voluntary blood donation that can be collected from open sources. The issue date and the revision date of each sample were recorded. With "The Blood Donation Law of the People’s Republic of China" as reference, 5 categories were formed and additional clauses in samples were coded and rated following content analysis procedures. Sample provinces were divided into two groups based on donation rate and their differences in evaluation scores of categories were examined using rank sum test. 【Results】 Until December, 2021, 31 sample provinces had issued and implemented provincial laws and regulation for voluntary blood donation, and 14 of which had been revised. Many detailed clauses (total score 9.32±3.09) were added in sample provincial laws and regulations, more clauses were added in the categories of 'related government agencies and their responsibilities’, 'management of clinical blood use’ and 'rewards and punishment’. Sample provinces were divided into two groups according to the donation rate per 1 000 people recommended by World Health Organization(10‰). Compared to lower donation rate group, the total score and sub score in the categories of 'basic principles’, 'management of blood collection and supply’ were significantly higher in higher donation rate group. 【Conclusion】 In revision and improvement of provincial laws and regulations, 'basic principles’ and 'management of blood collection and supply’ could be considered. This assay mainly tries to provide a new research perspective and perform quantitative analysis on content of sample provincial laws and regulation for voluntary blood donation, the actual effect of the results in this study need longer time to be examined, and we will keep following its new advances.
