ObjectiveBased on ultra-high performance liquid chromatography-quadrupole-electrostatic field orbital trap-linear ion-trap mass spectrometry(UPLC-Orbitrap Fusion Lumos Tribrid-MS), the plasma concentration of ziyuglycoside Ⅰ was determined at different time points after oral administration, and its pharmacokinetic characteristics in normal rats and rats with acute kidney injury were compared. MethodsRats were randomly divided into normal group and model group, the model group received intraperitoneal cisplatin(10 mg·kg-1) to establish the acute kidney injury model, the normal group was given the same volume of saline. After successful modeling, rats in the normal and model groups were randomly divided into the normal low, medium and high dose groups(2.5, 5, 7.5 mg·kg-1) and the model low, medium and high dose groups(2.5, 5, 7.5 mg·kg-1), 6 rats in each group, and the plasma was collected at different time points after receiving the corresponding dose of ziyuglycoside Ⅰ. Then, the concentration of ziyuglycoside Ⅰ in rat plasma was determined by UPLC-Orbitrap Fusion Lumos Tribrid-MS, and the drug-time curve was poltted. The pharmacokinetic parameters were calculated by Kinetica 5.1 software, and the differences in pharmacokinetic parameters between different administration groups were compared by independent sample t-test with SPSS 22.0. ResultsThe pharmacokinetic results showed that after receiving the different doses of ziyuglycoside Ⅰ, its concentration increased first and then decreased, and all of them reached the maximum plasma concentration at about 0.5 h. The area under the curve(AUC0-t) and mean retention time(MRT0-t) of normal and model rats increased with the increased dose, and the clearance(CL) decreased with the increasing dose. Compared with the normal group, the AUC0-t was significantly increased(P<0.01), peak concentration(Cmax) and CL decreased in model rats at different doses, indicating that the physiological state of the rats could affect the absorption and elimination of ziyuglycoside Ⅰ in vivo. ConclusionThe pharmacokinetic characteristics of ziyuglycoside Ⅰ are quite different in normal rats and acute kidney injury model rats, which may be due to the change of the body environment in the pathological state, then lead to changes in absorption and metabolic processes.

BackgroundInvasive vagus nerve stimulation therapy has been approved for the adjunctive treatment of treatment-resistant depression, which may contribute to the anti-inflammatory properties of vagus nerve stimulation (VNS), whereas the efficacy of non-invasive transcutaneous cervical vagus nerve stimulation (tcVNS) in treating major depressive disorder (MDD) and its impact on plasma inflammatory factors remain unclear. ObjectiveTo observe the effect of escitaloprom combined with tcVNS on the status of depression, anxiety and sleep quality as well as the plasma levels of interleukin-6 (IL-6) and interleukin-10 (IL-10) in MDD patients, in order to provide references for the recovery and treatment of MDD patients. MethodsFrom August 21, 2019 to April 17, 2024, 45 patients who met the diagnostic criteria for MDD in the Diagnostic and Statistical Manual of Mental Disorders, fifth edition (DSM-5) were recruited from the psychosomatic outpatient clinic of the First Affiliated Hospital of Air Force Military Medical University. Subjects were divided into study group (n=23) and control group (n=22) using random number table method. All patients were treated with escitalopram. On this basis, study group added a 30-minute tcVNS therapy once a day for 4 weeks. While control group was given corresponding sham stimulation, and the duration of each stimulation lasted 30 seconds. Before and after 4 weeks of treatment, Hamilton Depression Scale-17 item (HAMD-17) was used to assess depressive symptoms, and HAMD-17 anxiety/somatization subfactor and insomnia subfactor were used to assess patients' anxiety/somatization symptoms and sleep quality. Levels of plasma IL-6 and IL-10 were measured by enzyme-linked immunosorbent assay (ELISA). ResultsThe generalized estimating equation model yielded a significant time effect for HAMD-17 total score, anxiety/somatization subfactor score and insomnia subfactor score in both groups (Wald χ2=315.226, 495.481, 82.420, P<0.01). After 4 weeks of treatment, HAMD-17 total score and anxiety/somatization subfactor score of study group were lower than those of control group, with statistically significant differences (Wald χ2=4.967, 32.543, P<0.05 or 0.01), while no statistically significant difference was found in the insomnia subfactor score between two groups (Wald χ2=0.819, P=0.366). Significant time effects were reported on plasma IL-6 and IL-10 levels in both groups (Wald χ2=21.792, 5.242, P<0.05 or 0.01). Compared with baseline data, a reduction in plasma IL-6 levels was detected in both groups (Wald χ2=22.015, 6.803, P<0.01), and an increase in plasma IL-10 levels was reported in study group (Wald χ2=5.118, P=0.024) after 4 weeks of treatment. ConclusionEscitalopram combined with tcVNS therapy is effective in improving depressive symptoms, anxiety/somatization symptoms and sleep quality in patients with MDD. Additionally, it helps reduce plasma IL-6 levels and increase IL-10 levels.

Clinical practice guidelines represent the best recommendations for patient care. They are developed through systematically reviewing currently available clinical evidence and weighing the relative benefits and risks of various interventions. However, clinical practice guidelines have to go through a long translation cycle from development and revision to clinical promotion and application, facing problems such as scattered distribution, high duplication rate, and low actual utilization. At present, the clinical practice guideline information platform can directly or indirectly solve the problems related to the lengthy revision cycles, decentralized dissemination and limited application of clinical practice guidelines. Therefore, this paper systematically examines different types of clinical practice guideline information platforms and investigates their corresponding challenges and emerging trends in platform design, data integration, and practical implementation, with the aim of clarifying the current status of this field and providing valuable reference for future research on clinical practice guideline information platforms.

OBJECTIVE To provide references for ensuring the safety of prescription preparation, dispensing, and use of parenteral nutrition solution, as well as for expanding the scope of pharmaceutical services provided by pharmacists in the Pharmacy Intravenous Admixture Services (PIVAS). METHODS Under the guidance of PIVAS pharmacists, the rules for reviewing medical orders of parenteral nutrition in the PIVAS system and the information displayed on the infusion labels of finished parenteral nutrition solutions were refined. The process management of dispensing parenteral nutrition solution was strengthened, and detailed quality control and inspection rules were formulated. Additionally, Clinical Safety Monitoring Form for Finished Parenteral Nutrition Infusions was designed to conduct clinical monitoring and inspections for abnormalities in the finished infusions, infusion operations, and complications that may arise during the use of finished parenteral nutrition infusions. The implementation effects of the aforementioned optimization/inspection measures were evaluated by comparing data on the efficiency of medical order review for parenteral nutrition, the rate of irrational medical orders, the compliance rate of vascular access selection and infusion rate standardization, the rate of dispensing error, as well as the abnormalities occurring during clinical use, before and after the optimization/inspection initiatives were put into place. RESULTS The optimized prescription review system achieved automatic review of medical orders for parenteral nutrition, enhancing the efficiency of order review. The average time taken to review one parenteral nutrition medical order was reduced from approximately 1 minute to 10 seconds. The irrational rate of parenteral nutrition orders decreased by 31.87%. The dispensing error rate of parenteral nutrition decreased by 56.55%. The standard rate of vascular access selection and standard rate of infusion speed were increased by 13.29% and 3.54%, respectively. The PIVAS pharmacists identified and intervened in 5 abnormal cases out of 298 cases examined for use of parenteral nutrition solutions. CONCLUSIONS By optimizing the prescription review system, improving labeling information, and strengthening quality control inspections during both preparation and administration processes, PIVAS pharmacists have enhanced the safety of compounded parenteral nutrition solutions. This initiative has expanded the scope and depth of pharmaceutical care provided by dispensing pharmacists.

Objective To explore the value of combined ultrasound parameters, including the hepatorenal index (HRI) and renal resistance index (RRI), with cystatin C (CysC) in monitoring early acute kidney injury (AKI) after liver transplantation. Methods Perioperative data from 121 liver transplant recipients who received organs from donation after brain death were collected. The HRI and RRI of the recipients were measured on postoperative days 1-7 and at 1 month, and the CysC levels were measured on postoperative day 1. The recipients were divided into the AKI group (n=53) and the non-AKI group (n=68) based on whether AKI occurred within 7 days after operation. The data of the two groups were compared, and the ultrasound parameters before and after recovery in the AKI group were analyzed. The value of combined HRI, RRI and CysC in monitoring AKI was also analyzed. Results AKI occurred in 53 recipients, with an incidence rate of 43.8%, including 30 cases of stage 1, 18 cases of stage 2, and 5 cases of stage 3. Among them, 49 cases occurred on postoperative day 1, and 4 cases occurred on postoperative day 2. Of these, 43 cases recovered within 7 days after surgery, 8 cases recovered within 2 months after surgery, 1 case was lost to follow-up, and 1 case received renal replacement therapy. The body mass index and preoperative CysC levels were higher in the AKI group than in the non-AKI group, and the operative time was longer in the AKI group than in the non-AKI group (all P < 0.05). The HRI on postoperative day 1 was lower in the AKI group than in the non-AKI group, while the RRI and CysC levels were higher (all P < 0.05). When AKI occurred, the HRI was lower than the baseline level, and the RRI was higher than the baseline level. As AKI recovered, the HRI gradually increased, and the RRI gradually decreased. The receiver operating characteristic curve analysis showed that the sensitivity and specificity of HRI ≤ 1.12 for predicting AKI were 0.623 and 0.878, respectively, with an area under the curve (AUC) of 0.801. The sensitivity and specificity of RRI ≥ 0.65 for predicting AKI were 0.878 and 0.676, respectively, with an AUC of 0.825. The sensitivity and specificity of CysC ≥ 1.38 mg/L for predicting AKI were 0.736 and 0.882, respectively, with an AUC of 0.851 (all P<0.01). The combination of HRI and CysC (AUC=0.897, P<0.01), RRI and CysC (AUC=0.910, P<0.01), and all three parameters combined (AUC=0.934, P<0.01) were more effective than using each parameter alone. Conclusions HRI and RRI may be used to monitor the occurrence and recovery of early AKI after liver transplantation. The combination of these two parameters with CysC has a high application value in monitoring early AKI after liver transplantation.

Objective To establish radioresistant human non-small cell lung cancer NCI-H460R model cells and evaluate the sensitivity of these radioresistant cells to a ferroptosis inducer. Methods Radioresistant cell lines, designated as NCI-H460 R20Gy and NCI-H460 R116Gy, were generated by subjecting parental NCI-H460 cells to fractionated irradiation with varying cumulative doses. Both parental cells and the established radioresistant cell lines were each randomly divided into four groups and exposed to irradiation at 0, 2, 4, and 6 Gy, respectively. Successful establishment of the radioresistant cell lines was confirmed by colony formation assay. Subsequently, cells were treated with increasing concentrations of the ferroptosis inducer RSL-3 to assess differential sensitivity between parental and radioresistant cells to ferroptosis. Results In comparison to the parental NCI-H460 cells (D0WT=1.2), both NCI-H460 R116Gy and NCI-H460 R20Gy cells exhibited radioresistance, with NCI-H460 R116Gy demonstrating a stronger radioresistance (D0R116Gy=1.5) than NCI-H460 R20Gy (D0R20Gy=1.4). Furthermore, NCI-H460 R116Gy cells exhibited increased sensitivity to RSL-3 relative to the parental cells (P < 0.001), while NCI-H460 R20Gy cells did not display a significant difference in sensitivity to RSL-3. Conclusion Human non-small cell lung cancer cells with radioresistance induced by a high cumulative irradiation dose exhibit increased sensitivity to the glutathione peroxidase 4-specific ferroptosis inducer RSL-3. This finding provides an experimental basis for optimizing combined treatment regimens involving radiotherapy and RSL-3 for non-small cell lung cancer patients with radiotherapy resistance.

AIM:To evaluate corrective effect and stability of corneal morphology in patients with moderate to high myopia after 2a treatment of femtosecond laser assisted laser in situ keratomileusis(FS-LASIK)Xtra.METHODS:Retrospective case-control study. A total of 30 cases(58 eyes)Patients with moderate to high myopia combined with astigmatism who planned to undergo refractive surgery in our hospital from August 2019 to August 2020 were included, and different types of surgery were performed respectively based on the relevant index of keratoconus screening in the preoperative corneal topography. They were divided into FS-LASIK group and Xtra group, with 15 cases(29 eyes)in each group. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), spherical equivalent(SE)and the corneal curvature of the anterior and posterior surfaces of different diameters(3, 5 and 7 mm)measured by Sirius three-dimensional corneal topography were observed preoperatively and 3 mo, 1 and 2 a postoperatively.RESULTS: The UCVA of the two groups of patients at different time points after surgery was significantly increased compared with preoperatively(both P<0.01), and there was no difference in UCVA and SE between the two groups(P>0.05). After 2 a postoperatively, residual astigmatism was -0.25-0 D in 25 eyes(86%)of the FS-LASIK Xtra group and 24 eyes(83%)of the FS-LASIK group. The actual corrected SE and expected corrected SE of both groups were positively correlated(both P<0.05). There were differences in corneal curvature on the surface of different diameter areas(3, 5, and 7 mm)between the two groups at 3 mo, 1, and 2 a postoperatively compared with preoperatively. After 1 and 2 a postoperatively, the corneal posterior surface curvature of the FS-LASIK Xtra group with corneal diameter of 3 and 5 mm was higher than that of the FS-LASIK group(P<0.05).CONCLUSIONS:FS-LASIK Xtra has good safety, efficacy and predictability in correcting patients with moderate to high myopia.
