OBJECTIVE To study the pharmacokinetic characteristics of antidepressant active components from Jiaotai pills in healthy subjects. METHODS Eight healthy subjects （3 males and 5 females） were recruited and given a single oral dose of 8.55 g of Jiaotai pills. Venous blood samples were collected before administration （0 h） and at intervals from 0.25 to 36.0 hours post- administration. After treating the plasma samples with protein precipitation， the blood concentrations of the antidepressant active ingredients （coptisine， berberine， magnoflorine， and palmatine） in Jiaotai pills were determined using liquid chromatography- tandem mass spectrometry （LC-MS/MS） method. DAS 2.0 software was employed to calculate the pharmacokinetic parameters of healthy subjects [half-life （t1/2）， peak concentration （cmax）， time to peak concentration （tmax）， area under the concentration-time curve （AUC）， and mean residence time （MRT）] using a non-compartmental model. RESULTS After healthy subjects took Jiaotai pills， the drug-time curve of the four antidepressant active ingredients conforms to a two-compartment model and tmax values were similar， with all reaching peak blood concentrations within 2.00 to 4.00 hours post-administration. However， the t1/2 and MRT of coptisine and berberine were significantly longer than that of magnoflorine and palmatine. There were also significant differences in the AUC and cmax among the four antidepressant active ingredients， with magnoflorine exhibiting markedly higher AUC0-t and cmax compared to the other three components. CONCLUSIONS In this study，LC-MS/MS is used to analyze the pharmacokinetic characteristics of the antidepressant active ingredients from Jiaotai pills in healthy subjects， can provide valuable references for the clinical application of Jiaotai pills.

[Objective] To explore the key factors affecting the efficiency and safety of hematopoietic stem cell apheresis. [Methods] The clinical data of 59 healthy donors who underwent allogeneic hematopoietic stem cell donation in the First Affiliated Hospital of Anhui Medical University from January 2021 to June 2024 were retrospectively analyzed. The number of CD34⁺ cells was used to evaluate the eligibility of stem cell collection. The effects of donor gender, age, patient weight, as well as the number of WBC, MNC, RBC, Hb, HCT, PLT, CD34⁺ cells, CD34⁺ percentage and instrument operating parameters on collection efficiency were analyzed. [Results] A total of 59 donors were enrolled, and 68 occasions of stem cell apheresis were performed, with a qualified collection rate of 56%. Donor gender, age, patient weight, total blood circulation volume, anticoagulant dosage, collection time, calcium gluconate dosage and RBC, Hb, HCT levels were not significantly correlated with the collection effect (P>0.05). Multivariate logistic regression analysis showed that the number of MNC cells, CD34⁺ cells and stem cell product volume were the key factors affecting the efficiency and safety. A total of 12 donors had mild adverse reactions during the collection process, and all of them were improved after treatment. [Conclusion] Optimizing apheresis strategy based on the three factors of MNC, WBC count and stem cell product volume on the day of collection will help to achieve high-quality collection and improve the success rate of transplantation.

In August 2024,the European Society of Cardiology Working Group on the management of Peripheral Artery and Aortic disease issued the"Guidelines for the management of peripheral and aortic arterial disease".The guideline stated that peripheral artery and aortic diseases were very common,significantly increasing cardiovascular disease morbidity and mortality in the general population,and their prevention and treatment strategies needed to be strengthened.This article interpreted the content of antithrombotic drug therapy in the guideline from the perspective of drug therapy,which could provide a reference for clinicians and pharmacists to formulate antithrombotic strategies.

In January 2023,the European Society of Cardiology(ESC)Working Group on thrombosis published its 2022 updated consensus document on acute,perioperative,and long-term antithrombotic therapy for the elderly.Since the elderly are often accompanied with multiple organ changes and multiple diseases,the risk of hemorrhagic and ischemic events is increased,and they often take multiple drugs and have poor compliance with treatment,which pose significant challenges to clinical antithrombotic management.This article elaborates on how to assess the risk of thrombosis and bleeding,the treatment strategy of oral antithrombotic drugs,the treatment strategy of parenteral antithrombotic drugs,and the perioperative antithrombotic therapy protocols,with the aim of providing clinicians with references for the treatment of antithrombosis in the elderly.

Objective:To investigate the correlation between vitamin D deficiency and the severity of symptoms in children with vasovagal syncope (VVS).Methods:A prospective study was conducted. One hundred and twenty-two children diagnosed with VVS by head up tilt test in Department of Pediatric Cardiology and 130 healthy children without symptoms who underwent physical examination in the outpatient department of Child Healthcare Department of Second Hospital of Lanzhou University from December 2019 to May 2021 were selected and assigned to VVS group and control group, respectively. According to the diagnostic criteria of vitamin D deficiency, children in the VVS group were assigned to three subgroups: non-vitamin D deficiency, vitamin D deficiency, and severe vitamin D deficiency. All children underwent detailed history taking, physical examination, and level determination of serum 25 (OH) D. Children in the VVS group were scored for orthostatic intolerance (OI) symptoms including 10 symptoms: syncope, dizziness, nausea, palpitation, headache, tremor, chest tightness, blurred vision, profuse perspiration, and attention deficit. The differences in the age, gender, body mass index, blood pressure, and serum 25 (OH) D levels between VVS group and control group, and the differences regarding the age, gender, body mass index, blood pressure, serum 25 (OH) D levels and symptom scores among the three VVS subgroups were compared. Comparisons were performed using independent sample t test, ANOVA analysis, Chi square test and rank sum test. Pearson correlation analysis was used to analyze the correlation between serum 25 (OH) D levels and OI symptom scores in children with VVS. Results:The serum 25 (OH) D levels were significantly lower in the VVS group than those in the control group ((31±11) vs. (46±10) nmol/L, t=10.89, P<0.001). Vitamin D deficiency was more frequent in the VVS group (73.0% (89/122) vs. 24.6% (32/130), χ2=58.91, P<0.001). There were significant differences among the severe vitamin D deficiency subgroup, vitamin D deficiency subgroup, and non-vitamin D deficiency subgroup regarding the serum 25 (OH) D levels ((9.8±0.4) vs. (26.6±6.5) vs. (45.8±5.9) nmol/L, F=142.77, P<0.001) and the OI symptom scores ((14±1) vs. (10±2) vs. (7±2) scores, F=44.97, P<0.001). The scores of syncope, nausea, profuse perspiration, blurred vision and dizziness among the severe vitamin D deficiency subgroup, vitamin D deficiency subgroup, and non-vitamin D deficiency subgroup were statistically significant ( H=9.01, 7.52, 12.11, 7.07 and 9.54, respectively, all P<0.05). Pearson correlation analysis showed that the serum 25 (OH) D levels were negatively correlated with OI symptom scores in children with VVS ( r=-0.769, P<0.001). Conclusions:VVS children have significant vitamin D deficiency. The severity of symptoms increases with decreasing of vitamin D level. Syncope, nausea, and profuse perspiration are more likely to occur in children with severe vitamin D deficiency, and dizziness and blurred vision are more likely to occur in children with vitamin D deficiency.

Objective　To investigate the relationships between serum microRNA-210 (mir-210),hypoxia inducible factor-1α (HIF-1α) and delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH).Methods　Two hundred and sixty patients with aSAH who were diagnosed and treated in the Department of Neurosurgery of our hospital were selected as the study objects.According to the occurrence of DCI after aSAH,they were divided into non DCI group (181 patients) and DCI group (79 patients).The clinical data of the two groups were collected,the levels of serum mir-210 were determined by real-time fluorescent quantitative PCR (qRT-PCR),and the levels of HIF-1α in serum were determined by enzyme-linked immunosorbent assay (ELISA).Results　There were significant differences in aneurysm location,Hunt-Hess grade and Fisher grade between the two groups (P<0.05).The levels of mir-210 and HIF-1α in DCI group were significantly higher than those in non DCI group (P<0.05).Pearson test showed that there was a positive correlation between serum mir-210 level and HIF-1α level in aSAH patients (P<0.05).Multivariate logistic regression analysis showed that Hunt-Hess grade≥3,Fisher grade≥3 and high levels of serum mir-210 and HIF-1α were independent risk factors for DCI after aSAH (P<0.05).ROC curve analysis showed that the area under the curve of DCI after aSAH predicted by serum mir-210 combined with HIF-1α level was higher than that predicted by the two alone,with the sensitivity of 83.33% and the specificity of 94.44%.Conclusions　The levels of mir-210 and HIF-1α in patients with DCI after aSAH are all increased,which can be used as potential indexes to judge the occurrence of DCI after aSAH.

Objective:To evaluate the association betweew family history of diabetes and incident diabetes of adults.Methods:A total of 49 266 participants in the China Kadoorie Biobank (CKB) study from Wuzhong district of Suzhou city were included in the analysis, after the exclusion of those with heart disease, stroke, cancer and diabetes at baseline survey. The person-year of follow-up was calculated from the date on completion of baseline survey to the date on any firstly-occurred event, i.e., diabetes incidence, death, loss of follow-up, or December 31, 2013. Cox regression model was used to estimate the hazards ratios of the association between family history of diabetes and incident diabetes.Results:During 348 677 person-years of the follow-up (median 7.08 years), a total of 423 men and 791 women were diagnosed as having diabetes. Compared to those without diabetic family history, participants with family history of diabetes showed a higher risk of diabetes, with a HR (95% CI) of 1.90 (1.57-2.29), and the risk increased with the number of relatives suffering from diabetes ( P for trend<0.05). The family history of maternal type, sibling type, and sibling and parental type had a statistically significant association with the risk of diabetes. The adjusted HR (95% CI) was 2.03 (1.45-2.77), 2.07 (1.56-2.68) and 2.39 (1.14-4.34), respectively. Modification effects of tobacco smoking, alcohol drinking, body mass index and physical activity on the association between diabetic family history and risk of diabetes were not observed in the study ( P for interaction>0.05). Conclusions:Diabetic family history is associated with the increased incident diabetes, and the risk increased with the number of relatives suffering from diabetes.
