To standardize the clinical application of oral Chinese patent medicines （CPMs）， and address the safety issues arising from their dosage form characteristics， irrational clinical use， and the lack of targeted pharmacovigilance systems， the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines， aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China （2019 revision）， the Institute of Basic Research in Clinical Medicine， China Academy of Chinese Medical Sciences， led a drafting group comprising 18 institutions. After multiple rounds of expert interviews， literature retrieval， evidence screening， and extensive solicitation of opinions， the Guidelines were registered internationally. Systematic standardization focused on safety monitoring， risk identification， assessment， control， and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring， known risks， and potential risks， compared to non-oral CPMs. Then， risk control measures were proposed， including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs， the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine （TCM）， which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions， pharmaceutical manufacturers， and regulatory authorities.

BACKGROUND:Ca2+expression in astrocytes has been found to be closely related to cognitive function,and the Ca2+signaling pathway regulated by inositol 1,4,5-trisphosphate receptors(IP3R2)and ryanodine receptor(RYR)2 receptors has become a hot spot in the study of cognitive disorder-related diseases. OBJECTIVE:To investigate the expression of Ca2+signals mediated by IP3R2 and RYR2 in hippocampal astrocytes in animal models of delayed encephalopathy after acute carbon monoxide poisoning,and to explore the possible pathogenesis of delayed encephalopathy after acute carbon monoxide poisoning. METHODS:C57BL mice with qualified cognitive function were selected by Morris water maze experiment and randomly divided into control group and experimental group.An animal model of delayed encephalopathy after acute carbon monoxide poisoning was established by static carbon monoxide inhalation in the experimental group,and the same amount of air was inhaled in the control group.Behavioral and neuronal changes,astrocyte specific marker glial fibrillary acidic protein,IP3R2,RYR2 receptor and Ca2+concentration in astrocytes of the two groups were detected using Morris water maze,hematoxylin-eosin staining,western blot,immunofluorescence double labeling and Ca2+fluorescence probe at 21 days after modeling. RESULTS AND CONCLUSION:In the Morris water maze,the escape latency of the experimental group was significantly longer than that of the control group(P<0.05).Hematoxylin-eosin staining results showed that in the experimental group,the number of hippocampal pyramidal cells decreased,the cell structure was disordered,and the nucleus was broken and dissolved.Immunofluorescence results showed that IP3R2 and RYR2 were co-expressed with glial fibrillary acidic protein in the hippocampus,and the expressions of IP3R2,RYR2 and glial fibrillary acidic protein were up-regulated in the hippocampus of the experimental group(P<0.05).Western blot analysis showed that the expressions of IP3R2,RYR2,and glial fibrillary acidic protein in the hippocampus of the experimental group were increased(P<0.05).Ca2+concentration in hippocampal astrocytes increased significantly in the experimental group(P<0.05).To conclude,astrocytes may affect Ca2+signals by mediating IP3R2 and RYR2 receptors,then impair the cognitive function of mice with carbon monoxide poisoning,and eventually lead to delayed encephalopathy after acute carbon monoxide poisoning.

China has the highest number of smokers in the world with more than 1 million tobacco-related deaths each year.Smoking cessation is a feasible intervention to reduce the prevalence of smoking-related diseases and premature deaths.The smoking cessation therapies approved for use in China are ineffective for some tobacco dependent patients.In order to further improve the rate of smoking cessation,a combination of medications can be chosen,including varenicline combined with nicotine replacement therapy.However,there are conflicting evaluation conclusions on the effectiveness and safety of combination therapy.This article aims to review the mechanism of action,efficacy,and safety of varenicline combined with nicotine replacement therapy in the treatment of tobacco dependence,aiming to provide a basis for this combination therapy.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

This report details a successfully treated case of myxedema coma with cardiac attest, accompanied by a literature review, to enhance clinical awareness and improve the diagnosis and management of this critical condition.

Objective:To compare the value of different quantification methods for intraoperative hypotension in predicting postoperative acute kidney injury (AKI) in patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods:The medical records of American Society of Anesthesiologists Physical Status classification Ⅲ-Ⅳ patients of either sex, aged 18-80 yr, with a body mass index of 18-30 kg/m 2, scheduled for elective OPCABG, were retrospectively collected at Tianjin Chest Hospital from September 2021 to October 2023. Intraoperative hypotension was quantified using the methods such as the number of occurrence, average decrease in magnitude, duration, and the area under the threshold (mean arterial pressure <65 mmHg, 1 mmHg = 0.133 kPa). Patients were divided into AKI group and non-AKI group based on the occurrence of AKI within 7 days postoperatively. The extended logistic regression model was used to adjust for confounding factors, and the receiver operating characteristic curves were plotted to compare the accuracy of different methods for intraoperative hypotension in predicting postoperative AKI. Results:The results of multivariate logistic regression analysis showed that the frequency of hypotension ( OR=1.03, 95% confidence interval [ CI] 1.01-1.05, P=0.010), duration of hypotension ( OR=1.04, 95% CI 1.01-1.08, P=0.007), and area under the threshold ( OR=1.03, 95% CI 1.01-1.06, P=0.023) were risk factors for postoperative AKI. The areas under the curve for the quantification methods predicting the occurrence of postoperative AKI within 7 days, including the duration of hypotension, area under the threshold, frequency of hypotension, and mean decrease in blood pressure, were 0.751, 0.652, 0.647 and 0.513, respectively. Conclusions:The duration of hypotension, area under the threshold and frequency of hypotension are independent risk factors for postoperative AKI in patients undergoing OPCABG. The duration of hypotension has a higher accuracy in predicting the occurrence of postoperative AKI.
