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: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

OBJECTIVE: To assess the independent and combined effects of air pollutants, meteorological factors, and greenspace exposure on new tuberculosis (TB) cases. METHODS: TB case data from Shanghai (2013-2018) were obtained from the Shanghai Center for Disease Control and Prevention. Environmental data on air pollutants, meteorological variables, and greenspace exposure were obtained from the National Tibetan Plateau Data Center. We employed a distributed-lag nonlinear model to assess the effects of these environmental factors on TB cases. RESULTS: Increased TB risk was linked to PM _2.5, PM ₁₀, and rainfall, whereas NO ₂, SO ₂, and air pressure were associated with a reduced risk. Specifically, the strongest cumulative effects occurred at various lags: PM _2.5 ( RR = 1.166, 95% CI: 1.026-1.325) at 0-19 weeks; PM ₁₀ ( RR = 1.167, 95% CI: 1.028-1.324) at 0-18 weeks; NO ₂ ( RR = 0.968, 95% CI: 0.938-0.999) at 0-1 weeks; SO ₂ ( RR = 0.945, 95% CI: 0.894-0.999) at 0-2 weeks; air pressure ( RR = 0.604, 95% CI: 0.447-0.816) at 0-8 weeks; and rainfall ( RR = 1.404, 95% CI: 1.076-1.833) at 0-22 weeks. Green space exposure did not significantly impact TB cases. Additionally, low temperatures amplified the effect of PM _2.5 on TB. CONCLUSION Exposure to PM _2.5, PM ₁₀, and rainfall increased the risk of TB, highlighting the need to address air pollutants for the prevention of TB in Shanghai.

OBJECTIVE: To investigate chronic hepatitis C virus (HCV) infection's effect on gestational liver function, pregnancy and delivery complications, and neonatal development. METHODS: A total of 157 HCV antibody-positive (anti-HCV[+]) and HCV RNA(+) patients (Group C) and 121 anti-HCV(+) and HCV RNA(-) patients (Group B) were included as study participants, while 142 anti-HCV(-) and HCV RNA(-) patients (Group A) were the control group. Data on biochemical indices during pregnancy, pregnancy complications, delivery-related information, and neonatal complications were also collected. RESULTS: Elevated alanine aminotransferase (ALT) rates in Group C during early, middle, and late pregnancy were 59.87%, 43.95%, and 42.04%, respectively-significantly higher than Groups B (26.45%, 15.70%, 10.74%) and A (23.94%, 19.01%, 6.34%) ( P < 0.05). Median ALT levels in Group C were significantly higher than in Groups A and B at all pregnancy stages ( P < 0.05). No significant differences were found in neonatal malformation rates across groups ( P > 0.05). However, neonatal jaundice incidence was significantly greater in Group C (75.16%) compared to Groups A (42.25%) and B (57.02%) ( χ ² = 33.552, P < 0.001). HCV RNA positivity during pregnancy was an independent risk factor for neonatal jaundice ( OR = 2.111, 95% CI 1.242-3.588, P = 0.006). CONCLUSIONS Chronic HCV infection can affect the liver function of pregnant women, but does not increase the pregnancy or delivery complication risks. HCV RNA(+) is an independent risk factor for neonatal jaundice.

To investigate the pharmacological substances basis and anti-vitiligo mechanism of Carum carvi L. (caraway) fruits, chemical and blood-absorbed components were identified using mass spectrometry combined with literature study and database analysis. A “blood-absorbed components–target genes–pathways” network was constructed through network pharmacology. The pharmacological effects of Carum carvi L. extract and its key blood-absorbed component, acacetin, were validated in vitro. 72 chemical components were identified in the extract, with 11 prototype blood-absorbed components and 26 metabolites being detected in the plasma of SD rats. 14 key active components and 24 key targets were predicted. In vitro experiments demonstrated that acacetin at 10 μmol/L exhibited melanogenesis-promoting and tyrosinase-activating effects compared with the positive control, significantly upregulating the expression of microphthalmia-associated transcription factor (MITF) and tyrosinase (tyrosinase, TYR). This study comprehensively analyzes the chemical and blood-absorbed components of Carum carvi L. and elucidates its pharmacological substances basis, which provides a theoretical foundation for the anti-vitiligo effects of acacetin.

As a physical treatment technique, modified electro-convulsive therapy (MECT) is used to treat mental and certain neurological disorders by causing seizures with short, suitable electrical currents applied to the brain while the patient is under general anesthesia and muscle relaxants. MECT is recognized for its therapeutic efficacy and clinical safety, rendering it one of the most prevalent interventions in psychiatric care. To enhance clinical outcomes and minimize adverse effects, this consensus document delineates the indications, therapeutic parameters, therapeutic procedures, potential adverse effects, and associated management strategies for MECT. These guidelines are informed by the latest clinical research and expert consensus, integrating evidence-based medicine methodologies. The objective is to furnish clinicians with precise operational guidelines and to advance the standardization of MECT practices in clinical settings.

Aim To investigate the mechanism by which sufentanil(Suf)improved hypoxia-reoxygen-ation(H/R)-induced myocardial cell injury by regula-ting hypoxia inducible factor-1α(HIF-1α)and KC-NQ1 opposite strand/antisense transcript 1(Kcnq1ot1).Methods Bioinformatics analysis was conducted to predict the interaction between HIF-1αand Kcnq1ot1.Subsequently,H9c2 cells were divided into multiple treatment groups:Ctrl group,H/R group,and Suf group.Further grouping was based on different transfection conditions,including oe-HIF-1α group,oe-HIF-1α+Suf group,sh-HIF-1α group,and sh-HIF-1α+Kcnq1ot1 group.Cell viability was detected u-sing the MTT assay,cell apoptosis was detected using the TUNEL assay,and the concentrations of CK-MB and HBDH in cell supernatants were measured using ELISA.HIF-1α protein expression in cellswas deter-mined by Western blot,and the mRNA expression level of Kcnq1ot1 was measured by reverse transcription quantitative PCR(RT-qPCR).Additionally,a rat model of myocardial is chemia reperfusion was con-structed to evaluate the therapeutic potential of Suf for myocardial ischemia reperfusion injury in vivo.Results The results of bioinformatics analysis showed a direct interaction between HIF-1α and Kcnq1ot1.Compared with the Ctrl group,the H/R group showed significantly reduced H9c2 cell viability,increased cell apoptosis,and significantly upregulated concentrations of CK-MB and HBDH,along with significantly enhanced expres-sion of HIF-1α and Kcnq1ot1(all P＜0.05).When H9c2 cells were transfected with oe-HIF-1 α,cell via-bility further decreased,apoptosis was worsened,and CK-MB and HBDH concentrations further increased(all P＜0.05);however,these adverse effects were significantly inhibited when combined with Suf inter-vention(all P＜0.05).Additionally,compared with the H/R group,the sh-HIF-1α group showed signifi-cantly improved cell viability,reduced apoptosis and decreased CK-MB and HBDH concentrations(all P＜0.05);however,these improvements were partially re-versed upon transfection with Kcnq1ot1(all P＜0.05).Animal experiments confirmed that Suf could improve myocardial ischemia-reperfusion injury in myo-cardial ischemia-reperfusion injury rats.Conclusions Suf improves myocardial H/R injury by inhibiting the HIF-1α-Kcnq1ot1.

Objective:To investigate the safety and efficacy of Pipeline embolization device (PED) Shield in intracranial unruptured saccular aneurysms.Methods:This is a retrospective cohort study; 124 patients with intracranial unruptured saccular aneurysms treated with PED Shield at Department of Cerebrovascular Surgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from July 2023 to October 2024 were enrolled. Intraoperative device-related complications and occurrence of hemorrhagic and ischemic complications within 30 days of the procedure were recorded. The clinical results and imaging results (degrees of stent patency and aneurysm occlusion rate) 6 months after follow-up were statistically analyzed. Modified Rankin scale (mRS) score>2 was defined as poor prognosis in clinical follow-up, and grade D according to O'Kelly Marotta (OKM) classification was considered as complete aneurysm occlusion in imaging follow-up.Results:Eighty-seven females and 37 males, aged (56.44±12.17) years (ranging from 27 to 80 years) were enrolled, with a maximum aneurysm diameter of 5.12 (3.73, 7.24) mm. Among the 124 patients, incidence of intraoperative instrument-related complications was 6.5% (8/124); and within 30 days of the procedure, incidence of ischemic complications was 4.8% (6/124) and that of hemorrhagic complications was 1.6% (2/124). Eighty-four patients had a 6-month clinical follow-up, with 1 patient (1.2%) having poor prognosis. Eighty-four patients (67.7%) completed a 6-month imaging follow-up: complete occlusion rate of aneurysms was 82.1% (69/84), incidence of in-stent stenosis (stenosis degree ≥25%) was 4.8% (4/84), and no symptomatic in-stent stenosis was found.Conclusion:Result of this study shows that PED Shield may be an effective and safe clinical option for intracranial unruptured saccular aneurysms.

Objective:To investigate whether intermittent fasting alleviates insulin resistance in a polycystic ovary syndrome(PCOS) mouse model through the regulation of autophagy.Methods:Fifty 3-week-old female C57BL/6J mice were randomly assigned into the following groups using a random number table: normal control(NC) group( n=10), maintained on a standard chow diet; high-fat diet(HFD) group( n=10) fed a diet with 60% of calories derived from fat; and PCOS model group( n=30), established by combining a HFD with dehydroepiandrosterone(DHEA) administration. Successful modeling was confirmed by disrupted estrous cycles, hyperandrogenism, and polycystic ovarian morphology. The PCOS model mice were further divided into three groups: PCOS group( n=9), PCOS with intermittent fasting group(PCOS+ IF, n=9), and PCOS with intermittent fasting plus the autophagy inhibitor 3-methyladenine(3-MA) group(PCOS+ IF+ 3-MA, n=9). Autophagy levels were assessed by detecting markers LC3 and p62 and observing autophagosomes via transmission electron microscopy. Glucose tolerance test(GTT) and insulin tolerance test(ITT) were performed, and the area under the curve(AUC) was calculated to evaluate insulin resistance. Western blotting was used to detect phosphorylation levels of phosphatidylinositol 3-kinase(PI3K), protein kinase B(Akt), mammalian target of rapamycin(mTOR), and p70S6 kiase(p70S6K). Results:Compared with the NC group, the PCOS model group showed absent estrous cycles, significantly elevated serum testosterone, sex hormone binding globulin, and luteinizing hormone(LH) levels( P<0.001), and polycystic ovarian changes on hematoxylin-eosin staining, confirming successful model establishment. Immunohistochemistry, transmission electron microscopy, and Western blotting demonstrated that autophagy levels were increased in the PCOS+ IF group compared with the PCOS group, while 3-MA administration reduced the intermittent fasting - induced autophagy. The AUC values for both GTT and ITT were significantly lower in the PCOS+ IF group than those in the PCOS group( P<0.001, P=0.003), but increased in the PCOS+ IF+ 3-MA group compared to the PCOS+ IF group( P<0.001, P=0.020). Western blotting analysis showed that phosphorylation levels of PI3K, Akt, mTOR, and p70S6K were significantly decreased in the PCOS+ IF group compared with the PCOS group( P=0.002, P=0.001, P=0.001, and P<0.001, respectively), and increased in the PCOS+ IF+ 3-MA group compared with the PCOS+ IF group( P=0.021, P=0.041, P=0.047, and P=0.024, respectively). Conclusions:Intermittent fasting alleviates insulin resistance in a PCOS mouse model through inhibitiing PI3K/Akt/mTOR signaling pathway and promoting autophagy.
