    AIM: To explore the pharmacokinetic interactions between sorafenib and dapagliflozin in rats and to provide some theoretical basis for the rational clinical use of the two drugs. METHODS: An ultra-performance liquid chromatography-tandem mass spectrometry (UPLC/MS/MS) method was developed for the simultaneous determination of sorafenib and dapagliflozin. Male SD rats were randomly divided into 5 groups (6 rats in each group), including 100 mg/kg sorafenib group, 0.5 mg/kg dapagliflozin group, 1 mg/kg dapagliflozin group, and 100 mg/kg sorafenib combined with 0.5 mg/kg dapagliflozin group and 100 mg/kg sorafenib combined with 1 mg/kg dapagliflozin group, for sorafenib and dapagliflozin drug interaction study. All samples were analyzed using a validated UPLC/MS/MS method, and the main pharmacokinetic parameters were calculated by compartment model. RESULTS: 1 mg/kg dapagliflozin increased the Cmax, AUC0-t and AUC0-∞ of sorafenib by 52.5%, 38.1% and 37.7%, respectively, and 0.5 mg/kg dapagliflozin increased the AUC0-t and AUC0-∞ of sorafenib by 36.3% and 36.3%. CONCLUSION: Pharmacokinetic interactions may exist between sorafenib and dapagliflozin, active surveillance for treatment and toxicity should be required when the two drugs combined together in clinical practice.

    AIM: To explore the molecular mechanism of sequoiaflavone affecting gastric cancer cells. MEHTODS: Gastric cancer cell line AGS cells were treated with gradient concentrations of sequoiaflavone, and then induced by PI3K/AKT signaling pathway activator. The optimal inhibitory concentration and time of semi-inhibitory concentration of red cedar flavonoid on AGS cells were detected by CCK-8, and the changes of cell proliferation, migration and invasion ability were detected by colony formation assay, transwell assay and wound healing assay. PI3K/AKT signal pathway related proteins p-PI3K, PI3K, p-AKT and AKT  were detected by western blot. RESULTS: Sequoiaflavone inhibited AGS cells in a concentration-dependent manner. The half inhibitory concentration was 0.5 mmol/L, the optimal treatment time was 48 h. The protein expression of p-PI3K and p-AKT was down regulated. The proliferation, migration and invasion of AGS cells were decreased after treated with sequoiaflavone. After treated with PI3K/AKT signal pathway activator, the protein expression level of p-PI3K and p-AKT was partially reversed, and the ability of cell viability, proliferation, migration and invasion was also partially improved. CONCLUSION: Inactivation of PI3K/AKT signaling pathway caused by sequoiaflavone inhibited gastric cancer cells proliferation, migration and invasion ability.

    AIM: To investigate the effects of autotransfusion on immune function and inflammation in patients undergoing cesarean section. METHODS: Ninty patients with high risk hemorrhage (central placenta previa, cicatritic uterus, etc.) who underwent cesarean section were divided into three groups according to the amount of autoblood transfusion, with 30 cases in each group. The control group did not receive autologous blood transfusion, the group with a transfusion volume of 0-400 mL received autologous blood transfusion 0-400 mL, and the group with a transfusion volume of 400-800 mL received autologous blood transfusion 400-800 mL. Serum levels of HB, RBC, HCT, WBC, CD3+, CD4+ and CD8+ were detected before surgery (T0), immediately after surgery (T1), 24 h after surgery (T2), 48 h after surgery (T3), CD4+/CD8+ ratio was calculated, and serum levels of IL-2 and IL-6 were measured. The mean arterial pressure, heart rate, oxygen saturation, postoperative fever and length of stay were recorded. RESULTS: Compared with T0, the changes of CD3+, CD8+, CD4+/CD8+ ratio, IL-2 level, mean arterial pressure, heart rate and oxygen saturation were similar among the three groups at each time point after surgery (P>0.05). CD4+ in the 0-400 mL reinfusion group and the 400-800 mL reinfusion group was higher than that in T0 at T2 (P<0.05), and IL-6 and WBC in the three groups were higher than that in T0 at all time points after surgery (P<0.05). The levels of HB, RBC and HCT in the control group decreased at T1, while the levels of HB, RBC and HCT in the 0-400 mL and 400-800 mL reinfusion groups decreased at T2 (P<0.05). Comparison between groups: at the same time point after surgery, the ratio of CD3+, CD8+, CD4+/CD8+, IL-2, IL-6, HB, RBC, HCT, WBC, mean arterial pressure, heart rate, oxygen saturation, postoperative fever, length of hospital stay and other changes were similar among the three groups (P>0.05). CD4+ concentration in 0-400 mL reinfusion group and 400-800 mL reinfusion group was higher at T2 than that in control group (P<0.05). CONCLUSION: Autologous blood transfusion can not inhibit immune function, and even improve immune function in the short term. It will not aggravate the inflammatory response of the body, so it is safe and available.

    AIM: To compare the results calculated by population pharmacokinetic analysis tools Phoenix NLME, Monolix, R nlmixr package and CPhaMAS cloud platform with the gold standard sofeware NONMEM. METHODS: Fifty sparse sampling data sets based on a one-compartment model and fifty dense sampling data sets based on a two-compartment model were simulated, and the above five analysis tools were used to calculate the population typical value, individual variability and individual pharmacokinetic parameters. RESULTS: The population typical value and individual variability calculated by CPhaMAS and Phoenix NLME had the highest matching degree with NONMEM, followed by nlmixr. Monolix had the lowest matching degree, but Monolix and nlmixr might be more robust. The correspondence between clearance and distribution volume was better than the absorption rate constant. Except the absorption rate constant calculated by Monolix and intercompartmental clearance calculated by nlmixr, the correlation coefficients of individual pharmacokinetic parameters calculated by all analytical tools were greater than 0.99. CONCLUSION: The results calculated by the above four population pharmacokinetic analysis tools are highly correlated with that of NONMEM.

    AIM: To elucidate the relationship between childhood asthma susceptibility and clinical efficacy of inhaled glucocorticoids (ICS) in children with different genotypes of asthma by exploring rs776746 and rs15524 single nucleotide polymorphisms (SNPs) of cytochrome P450 enzyme 3A5 (CYP3A5) gene in asthmatic children and healthy children. METHODS: The CYP3A5 gene rs776746 and rs15524 polymorphic sites were detected in 79 children (Case group) with asthma of Han nationality and 100 healthy children (Control group) who met the inclusion criteria admitted to the Northern Theater General Hospital in Northeast China from October 2016 to October 2020, and genotype, allele and linkage analysis were performed. The case group was given inhaled glucocorticoids by nebulised inhalation for 3 months, and lung function and exhaled breath nitric oxide (FeNO) were measured at entry and after treatment, and asthma control score C-ACT/ACT was done after treatment, so as to compare the prevalence of different genotypes and the differences in the above test index scores. RESULTS: There was complete linkage disequilibrium at rs776746 and rs15524 loci. There were three genotypes of T/T, T/C and C/C at rs776746 locus of CYP3A5 gene. There were significant differences in the frequency of different genotypes between the case group and the control group (c2=9.121, P=0.010). The probability of asthma in T/C genotype was 6.345 times higher than that in T/T genotype (P=0.007), that in C/C genotype was 3.864 times higher than that in T/T genotype (P= 0.044), and that in variant type was 4.682 times higher than that in wild-type (P=0.011); There were three genotypes of A/A, A/G and G/G at rs15524 locus. There were significant differences in the frequency of different genotypes between the case group and the control group (c2=9.121, P=0.010). The probability of asthma of genotype A/A was 3.864 times higher than that of genotype G/G (P=0.044), and the probability of asthma of genotype A/G was 6.345 times higher than that of genotype G/G (P=0.007). When comparing the frequency of G/G and A/A+A/G in the case group and the control group, it was found that the probability of asthma of the latter was 4.682 times higher than that of the former (P=0.011). The improvement rate of the measured value of FEF50 and FEF75 at rs776746 was significantly higher than that of wild type (t=-2.499, -3.256, P=0.024, 0.019), and the improvement rate of the measured value of FEF50 and FEF75 at rs15524 was significantly lower than that of wild-type (t=3.380, 2.325, P=0.015, 0.042). The C-ACT/ACT score of rs776746 locus variant was significantly higher than that of wild-type group (t=0.571, P=0.037); There was no significant difference between wild-type and variant C-ACT/ACT scores at rs15524 locus (t=0.486, P=0.545). CONCLUSION: The rs776746 and rs15524 loci of CYP3A5 gene are the susceptibility loci of childhood asthma. The wild-type or variant of rs776746 and rs15524 loci are related to the improvement of small airway function after inhaled ICs treatment. Wild type or variant of rs776746 locus also affected asthma control.

    AIM: To explore the role of clinical pharmacist in the treatment of patients with transjugular intrahepatic portosystemic shunt. METHODS: Clinical pharmacist participated in the treatment of a patient with repeated oral bleeding after transjugular intrahepatic portal shunt followed treatment with multiple antithrombotic drugs, which assisted the physician to diagnose and adjust the antithrombotic treatment plan as well as provided the patient with whole-process pharmaceutical care and online management. RESULTS: Based on the inquiry about the patient's past and current medical history and medication consumption, the pharmacist considered that there was weak correlation between oral hemorrhage and antithrombotic drugs and advised for dentist inspection. Thereafter, the patient was diagnosed with chronic gingivitis. The dosage of warfarin was adjusted, and the pharmacists managed it online after discharge to achieve stable INR of the patient. In the later online follow-up, an abnormal increase of INR was encountered, By asking about the history of medication, it was considered that the increase in INR was related to taking amoxicillin capsules. Therefore, the pharmacist suggested to stop amoxicillin capsule and to gradually adjust the dose of warfarin to the original level to improve the treatment. CONCLUSION: The involvement of clinical pharmacists in clinical treatment facilitates comprehensive pharmaceutical care of patients, which plays a positive role in the efficacy and safety of medication therapy.

    The incidence of augmented renal clearance (ARC) in intensive care patients (ICU) is exceptionally high, and these patients are often comorbid with infection. The occurrence of ARC will significantly increase the clearance rate of antibiotics, making it difficult for conventional doses to reach effective therapeutic concentrations and affect the patient's anti-infective treatment effect and prognosis. It can be seen that it is crucial to formulate a reasonable dosing regimen for ICU patients with ARC. Regrettably, few reports in China about the adjustment strategy of antibiotic dosing regimens for ARC patients. Therefore, this article reviews the domestic and foreign literature for reference to provide evidence for medical personnel to adjust the dose of antibacterial drugs for such patients.
