OBJECTIVE To explore the efficacy and safe ty of Tripterygium wilfordii polyglycoside combined with finerenone in the treatment of diabetic nephropathy （DN）. METHODS This study selected 104 DN patients admitted to the Nephrology Department of Handan Central Hospital from January 2023 to May 2024 as the subjects and randomly assigned them into the control group （52 cases） and the combination group （52 cases）. All patients received basic treatment such as lipid-lowering and blood glucose control. On this basis， patients in the control group received finerenone， while those in the combination group received a combination therapy of T. wilfordii polyglycoside and finerenone. Both groups underwent treatment for a duration of three months. The two groups were compared in terms of clinical efficacy， renal function indicators [24-hour urine protein excretion （24 h UPE）， urinary albumin-to-creatinine ratio （UACR）， urinary albumin excretion rate （UAER） ] ， inflammatory factors [high mobility group box 1 protein （HMGB1）， interleukin-6 （IL-6）， nuclear factor-κB （NF-κB）， high-sensitivity C reactive protein （hs-CRP） ] ， and oxidative stress indicators [total antioxidant capacity （T-AOC）， superoxide dismutase （SOD）， advanced oxidation protein products （AOPP）， malondialdehyde （MDA） ] before and after treatment. Additionally， the occurrence of adverse drug reactions was recorded. RESULTS In terms of efficacy， the total effective rate of patients in the combination group was higher than that of the control group （ P ＜0.05）. After treatment， the levels of 24-h UPE， UACR， UAER， HMGB1， IL-6， NF-κB， hs-CRP， AOPP and MDA in the two groups were significantly lower than those in the same group before treatment； the levels of T-AOC and SOD in the two groups were significantly higher than those in the same group before treatment， with the combination group showing superior changes in the above indicators compared to the control group at the corresponding time point （ P ＜0.05）. In terms of safety， there was no statistical significance in the total incidence of adverse drug reactions between the two groups （ P ＞0.05）. CONCLUSIONS Compared to finerenone monotherapy， the combination therapy of T. wilfordii polyglycoside and finerenone demonstrates significant efficacy in treating DN. It effectively reduces proteinuria levels， alleviates inflammatory reaction， mitigates oxidative stress， and does not increase the risk of adverse reactions.

OBJECTIVE To explore optimization pathways for the drug traceability code management model in outpatient pharmacy workflows， providing practical evidence for enhancing the efficiency of pharmaceutical service. METHODS Taking the outpatient pharmacy of the First Affiliated Hospital of Sun Yat-sen University as the research subject， a comprehensive drug traceability system was established through three key interventions： upgrading the information system architecture [including integration of the hospital information system （HIS） with the traceability platform]， workflow optimization （reorganizing the inventory-dispensing-verification tripartite process）， and designing a dual-mode traceability data collection mechanism （primary data capture at dispensing stations and supplementary capture at verification stations）. Operational efficiency differences before and after implementation were analyzed using the medical insurance data and service timeliness metrics in September 2024. RESULTS After the implementation of drug traceability code management， in terms of data collection: Mode Ⅰ （verification-stage capture） uploaded 26 144 records， while Mode Ⅲ （inventory-as-sales capture） uploaded 443 061 records， totaling 469 205 entries； in terms of time efficiency： average drug dispensing time increased from 28.74 s to 43.37 s （enhanced by 51%）. Through dynamic staffing adjustments， patient wait time only extended from 8.04 min to 8.67 min （enhanced by 8%）. CONCLUSIONS Drug traceability code management can be effectively implemented via a “system reconstruction-process reengineering-human-machine collaboration” trinity strategy， leveraging informatization （e.g.， dual-mode data capture） to offset manual operation delays， which validates the feasibility of balancing national traceability demands with service efficiency in outpatient pharmacies.

Objective To systematically analyze the medical radiation exposure levels in a district of Ningbo City and to provide a scientific basis for the reasonable and effective control of medical radiation exposure. Methods Based on the radiological diagnosis frequency and dose information system, basic medical radiation exposure data were collected, such as radiation doses received by patients in various X-ray diagnostic examinations, from all 13 public medical institutions in a district of Ningbo City from January 1 to December 31, 2020. The data were analyzed for the percentage and collective effective dose of various diagnostic examinations, the distribution of examinations by sex and age, and the number of patients undergoing two or more examinations and their cumulative doses within multiple time intervals. Results Among medical X-ray diagnostic examinations in the district, the percentages of CT examination and routine photography examination were 50.88% and 47.93%, respectively, and the collective effective dose of CT examination accounted for 97.75%. By age and sex, the frequency of examination was the highest in the age group of 45-54 years, and the frequency of examination in the male was higher than that in the female before age 55. The annual effective dose for two patients exceeded 100 mSv. Conclusion In this study, CT examination accounted for up to 50.88% of all medical X-ray diagnostic examinations, and contributed 97.75% of the collective effective dose, highlighting the need for particular attention to the justification of medical radiation exposure from CT.

The prevalence of Class III malocclusion varies among different countries and regions. The populations from Southeast Asian countries (Chinese and Malaysian) showed the highest prevalence rate of 15.8%, which can seriously affect oral function, facial appearance, and mental health. As anterior crossbite tends to worsen with growth, early orthodontic treatment can harness growth potential to normalize maxillofacial development or reduce skeletal malformation severity, thereby reducing the difficulty and shortening the treatment cycle of later-stage treatment. This is beneficial for the physical and mental growth of children. Therefore, early orthodontic treatment for Class III malocclusion is particularly important. Determining the optimal timing for early orthodontic treatment requires a comprehensive assessment of clinical manifestations, dental age, and skeletal age, and can lead to better results with less effort. Currently, standardized treatment guidelines for early orthodontic treatment of Class III malocclusion are lacking. This review provides a comprehensive summary of the etiology, clinical manifestations, classification, and early orthodontic techniques for Class III malocclusion, along with systematic discussions on selecting early treatment plans. The purpose of this expert consensus is to standardize clinical practices and improve the treatment outcomes of Class III malocclusion through early orthodontic treatment.

Objective:To analyze the blood differential metabolites of patients with intrahepatic cholestasis (IHC) by liquid chromatography-mass spectrometry metabolomics technology so as to find potential metabolic target.Method:Serum samples were collected from thirty patients with intrahepatic cholestasis and thirty healthy individuals after metabolomics analysis. The differential metabolites were initially screened based on the multiple differences and significance. KEGG enrichment analysis was performed on the differential metabolites to determine the candidate targets. The potential clinical application value of these characteristic metabolites was analyzed using the receiver operating characteristic curve.Result:A total of thirty patients with intrahepatic cholestasis and thirty healthy adults were included. The age difference between the two groups was not statistically significant ( P>0.05). The clinical condition was consistent with the statistically significant differences in liver biochemical indicators, blood routine, coagulation, and inflammatory indicators between the two groups ( P<0.05). Furthermore, a blood metabolomics screening analysis revealed 99 differentially expressed metabolites associated with intrahepatic cholestasis. Of these, 15 showed statistically significant differences. Glucose, lipid, and energy metabolisms were the various primary types of differential metabolites involved. The receiver operating characteristic curve>0.9 included the following twelve kinds of metabolites: 1H-indole-3-carboxaldehyde, 6-hydroxy-1H-indole-3-acetamide, phenylalanyl tryptophan, 1-methylguanosine, 2-ethoxy-5-methylpyrazine, p-hydroxybenzaldehyde, 5-(2-chlorophenyl)-3,4-dihydro-2H-pyrrole, methylthioadenosine, alanylisoleucine, anabsinthin, N-acetyl-DL-histidine monohydrate, N-methylnicotinamide, and others. The fifteen metabolites that were previously identified and calculated according to the differential quantitative value of the metabolite corresponding ratio exhibited fold-changes in the upregulated and downregulated potential biomarkers (phenylalanine tryptophan, phenylalanine, 5'-methylthioadenosine, anabsinthin, and N-methylnicotinamide) in combination with the area under the receiver operating characteristic curve>0.9. Conclusion:Phenylalanyl tryptophan, phenylalanylalanine, 5'-methylthioadenosine, anabsinthin, and N-methylnicotinamide may serve as potential metabolic markers to distinguish patients with cholestasis from healthy controls. N-methylnicotinamide, among them, is of great importance as a potential marker.

Objective:To compare the influence of dronedarone and amiodarone on the bleeding risk of patients with atrial fibrillation treated with rivaroxaban anticoagulation.Methods:Clinical data of 81 patients with atrial fibrillation treated with rivaroxaban anticoagulation at Xi'an International Medical Center Hospital from January 2020 to July 2023, including 36 patients treated with dronedarone and 45 patients treated with amiodarone, were retrospectively analyzed. The effects of dronedarone and amiodarone on the anticoagulation of rivaroxaban were compared using the incidence of bleeding events, thrombosis events, and adverse reactions as outcome measures.Results:The total bleeding in the dronedarone group [22.22% (8/36)] was significantly higher than that in the amiodarone group [6.67% (3/45)] ( χ2 = 4.12, P < 0.05). The total bleeding of conventional-dose rivaroxaban in the dronedarone group was 30.00% (6/20), while the total bleeding of low-dose rivaroxaban was 12.50% (2/16), with no statistical significance ( χ2 = 1.58, P > 0.05). No thrombotic events or adverse reactions to dronedarone or amiodarone were observed in all patients. Conclusion:Compared with amiodarone, dronedarone significantly increases the bleeding risk of rivaroxaban anticoagulation in patients with non-valvular atrial fibrillation, and reducing the dose of rivaroxaban in patients using dronedarone does not reduce the bleeding risk.
