Animal experiments are essential tools in biomedical research, serving as a bridge between basic research and clinical trials. Systematic reviews and meta-analyses (SRs/MAs) of animal experiments are crucial methods for integrating evidence from animal experiment, which can facilitate the translation of findings into clinical research, reduce translational risks, and promote resource integration in basic research. With the continuous development of the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) methodology, its application in SRs/MAs of animal experiments has gained increasing attention. This article first outlines the principles and specific applications of the GRADE methodology in SRs/MAs of animal experiments, including qualitative descriptive systematic reviews, meta-analyses, and network meta-analyses. It then deeply analyzes the misuse of the GRADE methodology in practice, including incorrect evidence grading, improper classification of evidence, misapplication in qualitative systematic reviews, inconsistencies between the documentation of the upgrading and downgrading process and results, and inappropriate use for making recommendations. Furthermore, this article comprehensively discusses the factors influencing the grading of evidence certainty in SRs/MAs of animal experiments, including the impact of bias risk, indirectness, inconsistency, imprecision, and publication bias on evidence downgrading, as well as the role of large effect sizes and cross-species consistency in evidence upgrading. Finally, in response to the issues discussed, improvement strategies are proposed, including further research and optimization of the GRADE methodology for SRs/MAs of animal experiments, the development of reporting guidelines tailored to the characteristics of SRs/MAs in animal experiment research, and enhanced professional training for researchers in the GRADE methodology. This article aims to improve the quality of evidence in SRs/MAs of animal experiments, strengthen their reliability in clinical decision-making, and promote the more efficient translation of findings from animal experiment research into clinical practice.
2.Relationship among psychological resilience, parental control, and behavioral problems in junior high school students in Guizhou Province
Chinese Journal of School Health 2024;45(5):689-692
Objective:
To investigate the relationships among psychological resilience, parental control, and behavioral problems in middle school students, aiming to provide evidencebased recommendations for the prevention and intervention of behavioral issues in middle school students, as well as for the development of related policies.
Methods:
A stratified cluster sampling method was used to select 2 745 participants from three cities in Guizhou Province with different levels of economic development from August to December 2021. The Child Behavior Checklist (CBCL), Parental Control Questionnaire, and Psychological Resilience Questionnaire were administered to junior high school students and their parents. A network analysis method was employed to construct a network analysis model of factors influencing behavioral problems.
Results:
The detection rate of behavioral problems among junior high school students in Guizhou Province was 22.62%. The scores for psychological resilience (goal focus, emotional control, positive cognition, family support, and interpersonal assistance) and proactive inquiry in behavior control were higher in the group without behavioral problems than in the group with behavioral problems. Scores for psychological control (inducing guilt, with drawing affection, and asserting authority) were higher in the group with behavioral problems than in the group without behavioral problems, with statistically significant differences (t=9.80, 17.76, 6.21, 12.20, 13.18, 6.28, 11.58, 11.10, 10.74, P<0.05). The network model showed that among the same variable factors, the strongest connection weight was between inducing guilt and withdrawing affection, with a weight of 0.79. Between different variables, there were negative correlation between behavioral problems and psychological resilience (goal focus, emotional control, positive cognition, family support, interpersonal assistance) and behavior control (proactive inquiry, behavioral restraint) with correlation coefficients (r=-0.25, -0.42, -0.16, -0.31, -0.33, -0.17, -0.03, P<0.05), respectively. There were positive correlation between psychological control factors (inducing guilt, withdrawing affection, and asserting authority) and behavioral problems (r=0.29, 0.27, 0.27), and a negative correlation between these psychological control factors and psychological resilience factors (goal focus, emotional control, positive cognition, family support, interpersonal assistance)(r=-0.53--0.13)(P<0.05). The strongest connection weight was between withdrawing affection and family support, with a connection weight of -0.53. Family support was an important bridge symptom connecting the entire behavioral problem network model, with a high centrality.
Conclusions
The detection rate of behavioral problems among junior high school students in Guizhou Province is relatively high. Assisting adolescents in establishing a supportive family environment facilitates the cultivation of their psychological resilience, thereby mitigating the occurrence of behavioral problems.

Integrating evidence from animal experiments is a critical component of biomedical research, providing essential prior information for in-depth investigations of disease mechanisms and new drug development. Animal models have played an irreplaceable role in simulating human diseases. However, the integration of evidence from animal experiments has faced numerous challenges, including insufficient emphasis, significant heterogeneity in study designs, high publication bias, and discrepancies with clinical research practices. This paper first identifies existing issues in the original research evidence from animal experiments, such as the selection and applicability of animal models, considerations in the design of experimental studies, and factors influencing the translation of animal experimental evidence. It then discusses various methods for integrating this evidence, including systematic review and meta-analysis, overview of systematic review/umbrella review, scoping review, and evidence mapping, while highlighting recent advancements in their application. Finally, the paper addresses the main challenges currently encountered in the integration of evidence from animal experiments and proposes targeted improvement strategies aimed at enhancing the efficiency of translating research outcomes into clinical practice and promoting the advancement of evidence-based medicine. By continuously optimizing original experimental research protocols and evidence integration practices, this work aims to establish a more efficient and scientific environment for the synthesis of evidence from animal experiments, ultimately contributing to clinical trials and human health.

OBJECTIVE To provide reference for the management of antithrombotic therapy in thrombocytopenia patients with atrial fibrillation and atherosclerosis. METHODS The clinical pharmacist participated in the treatment of a thrombocytopenia patient with atrial fibrillation and atherosclerosis, and analyzed the causes of thrombocytopenia according to the patient’s medical history and laboratory examination results. At the same time, the risk of thrombosis-bleeding was evaluated according to the relevant guidelines, and the clinicians were assisted in formulating individual antithrombotic therapy plan and pharmaceutical care plan for the patient. The literature on antithrombotic therapy related to thrombocytopenia was collected and analyzed by retrieving CNKI. RESULTS Thrombocytopenia was considered as primary thrombocytopenia in this patient, and the main risk of bleeding was age ≥65 years old, bleeding tendency, and combined use of antithrombotic drugs. After the clinical pharmacist assessed the risk of thrombosis and bleeding, the clinician was recommended to give full dose of Bemiheparin sodium injection + Dronedarone hydrochloride tablets + Metoprolol succinate sustained-release tablets. In view of thrombocytopenia, the clinician gave Compound zaofan pill, Caffeic acid tablet and Sheng xuexiaoban capsule, but the patient developed diarrhea after the medication. The clinical pharmacist suggested stopping Sheng xuexiaoban capsule, and the clinician adopted the clinical pharmacist’s suggestion. When the patient was discharged from hospital, the clinical pharmacist suggested that the antithrombotic therapy plan for discharge was anticoagulation alone or selective anticoagulation. The clinician chose selective anticoagulation treatment considering that the patient’s current thrombocytopenia, urinary occult blood (+) and fecal occult blood were weakly positive, and ordered the patient to take Metoprolol succinate sustained-release tablets + Atorvastatin calcium tablets at discharge. Literature analysis showed that the causes of thrombocytopenia of patients with thromboembolism mainly included heparin induced-thrombocytopenia, immune thrombocytopenia, etc. All patients were improved after symptomatic treatment. CONCLUSIONS By participating in the management of antithrombotic therapy for the thrombocytopenia patient with atrial fibrillation and atherosclerosis, clinical pharmacists can help effectively control the patient’s condition and ensure the safety and effectiveness of drug use.

OBJECTIVE To provide a reference for the safe use of drugs in patients with complex venous thromboembolism (VTE) and acute renal insufficiency. METHODS Clinical pharmacists participated in the management of anticoagulant therapy for a patient with complex VTE complicated with acute renal insufficiency, and evaluated the patient as high-risk thrombosis and bleeding based on their medical history, laboratory test results, etc.; combined with the complexity of thrombosis and renal insufficiency, clinical pharmacists suggested that enoxaparin sodium should be used in the acute stage of thrombosis (5 to 21 days after onset), and then warfarin should be adopted for oral anticoagulation treatment. Because the patient’s anticoagulation was not up to the standard (the target range of the international normalized ratio was 2-3), clinical pharmacists suggested increasing the warfarin dose, detecting the warfarin metabolism genotype, and adjusting the warfarin dose according to the genotype; at the same time, clinical pharmacists developed an anticoagulation monitoring plan to ensure the safety of anticoagulation treatment. RESULTS Doctors had adopted all the recommendations of clinical pharmacists. The patient did not experience adverse events such as bleeding or worsening of thromboembolism during anticoagulation in the hospital. When the anticoagulation met the standards, the patient was allowed to be discharged with medication. CONCLUSIONS By participating in the anticoagulation treatment management of patients with complex VTE and acute renal insufficiency, clinical pharmacists have assisted doctors in formulating personalized anticoagulation plans to promote the compliance with the anticoagulation treatment standard and ensure the safety and effectiveness of medication for patients.

Objective:To explore the relationship between metabolic acidosis and cardiac valve calcification in maintenance hemodialysis (MHD) patients in the Pearl River Delta Region.Methods:Patients on MHD greater than 3 months who were treated in 10 blood purification centers in the Pearl River Delta Region from July 1 to September 30, 2019 were selected for this multicenter cross-sectional study. Based on a Doppler ultrasound, MHD patients were further divided into non-valve calcification group and valve calcification group. The demographics data, frequency of dialysis, blood pressure, single pool Kt/V(spKt/V), dialysis medications and laboratory data were collected and compared. Spearman correlation analysis was used to analyze the correlation between serum carbon dioxide combining power (CO 2CP) and cardiac valve calcification. Multivariate logistic regression model was used to analyze the influencing factors of cardiac valve calcification. Results:A total of 664 MHD patients were included in this study, with age of (57.0±14.2) years old and dialysis age of 43.0 (22.3, 71.7) months, including 395 males (59.5%) and 269 females (40.5%). Among them, there were 119 patients (17.9%) with diabetes and 186 patients (28.0%) with dialysis 2 times per week. There were 329 patients (49.5%) in the valve calcification group, and 335 patients (50.5%) in the non-valve calcification group. Compared to those in non-valve calcification group, valve calcification group had longer duration of dialysis, higher proportion of patients with dialysis 2 times per week, higher levels of diastolic blood pressure, fasting blood glucose, intact parathyroid hormone and ferritin, higher proportion of patients with blood CO 2CP<19 mmol/L (median CO 2CP), higher proportion of patients on usage of calcium channel blocker, angiotensin converting enzyme inhibitor/angiotensin receptor blocker, α-receptor blocker, β-receptor blocker, calcitriol and lanthanum carbonate (all P<0.05), while the levels of spKt/V, hemoglobin, serum CO 2CP, corrected calcium, blood phosphorus, blood alkaline phosphatase, albumin, total cholesterol, triacylglycerol, low-density lipoprotein, high-density lipoprotein, transferrin saturation, and the proportion of patients on usage of sevelamer and cinacalcet were lower (all P<0.05). Spearman analysis showed significant negative correlation between serum CO 2CP and valve calcification ( rs=-0.697, P<0.001). Multivariate logistic regression analysis showed that dialysis performed twice a week ( OR=2.789, 95% CI 1.232-6.305, P=0.014), blood total cholesterol ( OR=1.449, 95% CI 1.014-2.071, P=0.042), CO 2CP<19 mmol/L ( OR=22.412, 95% CI 10.640-47.210, P<0.001) were the influencing factor of valve calcification in MHD patients. Conclusions:MHD patients with cardiac valve calcification have significant acid loading. Metabolic acidosis is an independent influencing factor for cardiac valve calcification in MHD patients.

Objective To compare the hemodynamic characteristics in internal carotid artery models, which were obtained by multi-scale unidirectional and bidirectional coupling models, so as to provide references for selecting models in further studies. Methods Based on the nuclear magnetic resonance image of one patient with mild stenosis of internal carotid artery, the lumped parameter model of the circle of Willis and the three-dimensional model of internal carotid artery were constructed. Those two different multi-scale models were constructed by unidirectional and bidirectional coupling. Results With the increase of stenosis degree, the inlet and outlet blood pressure and the outlet blood flow of internal carotid artery all decreased under two kinds of coupling method. The distribution of low time average wall shear stress (TAWSS) and high oscillatory shear index (OSI) of the internal carotid artery both increased with the increase of stenosis degree under two kinds of coupling method in general. The anterior cerebral artery segment showed lower shear stress and higher OSI with bidirectional coupling in 70% stenosis, and the blood flow direction of posterior communicating artery was changed, which was significantly different from unidirectional coupling results. Conclusions At a low degree of stenosis, the result of those two kinds of coupling method were consistent in general, but there was a significant difference in 70% stenosis, and the result of bidirectional coupling was closer to physiological parameters. The research findings can be better applied to the hemodynamic study of cerebrovascular diseases.
