OBJECTIVE To evaluate the cost-effectiveness of finerenone combined with standard treatment regimen in the treatment of diabetic nephropathy （DN）. METHODS From the perspective of healthcare service providers， a Markov model was established to simulate the dynamic changes of each stage in DN patients who received finerenone combined with the standard treatment regimen or the standard treatment regimen alone based on the phase Ⅲ clinical trial study of finerenone for DN. Markov model was used to perform the cost-effectiveness of long-term effects and the costs of the two therapies with a simulation cycle of 4 months， a simulation period of 15 years and an annual discount rate of 5%. At the same time， one-way sensitivity analysis and probability sensitivity analysis were performed， and the stability of the results was validated. RESULTS Accumulative cost of the standard treatment regimen was 579 329.54 yuan， and the accumulative utility was 8.052 4 quality-adjusted life year （QALYs）； the accumulative cost of finerenone combined with the standard treatment regimen was 332 520.61 yuan， and the accumulative utility was 8.187 4 QALYs. Finerenone combined with the standard treatment regimen was more cost-effective. The results of one-way sensitivity analysis showed that dialysis status utility value， DN stage 3 utility value and DN stage 4 utility value had a great influence on the incremental cost-effectiveness ratio， but did not affect the robustness of the model. The results of probability sensitivity analysis showed that finerenone combined with the standard treatment regimen was more cost-effective with 100% probability. CONCLUSIONS For DN patients， finerenone combined with the standard treatment regimen is more cost-effective as an absolute advantage option.

ObjectiveTo investigate the anti-Alzheimer's disease （AD） effect of Dipsacus asper（DA） in the Caenorhabditis elegans model， and decipher the underlying mechanism via the peroxisome proliferator-activated receptor α （PPARα）/transcription factor EB （TFEB） pathway. MethodsFirst， transgenic AD C. elegans individuals were assigned into the blank control， model， positive control （WY14643， 20 µmol·L^-1）， and low-， medium-， and high-dose （100， 200， and 400 mg·L^-1， respectively） DA groups. The amyloid β-42 （Aβ₄₂） formation in the muscle cells， the paralysis time， and the deposition of amyloid β-protein （Aβ） in the head were detected. The lysosomal autophagy in the BV2 cell model was examined by Rluc-LC3wt/G120A. The expression levels of lysosomal autophagy-related proteins LC3Ⅱ， LC3I， LAMP2， and TFEB were detected by Western blot. Real-time quantitative polymerase chain reaction （Real-time PCR） was employed to determine the mRNA levels of autophagy-related genes beclin1 and Atg5 and lysosome-related genes LAMP2 and CLN2 downstream of PPARα/TFEB. A reporter gene assay was used to detect the transcriptional activities of PPARα and TFEB. Immunofluorescence was used to detect the fluorescence intensity of PPARα， and the active components of the ethanol extract of DA were identified by UPLC-MS. RCSB PDB， Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP）， and Autodock were used to analyze the binding between the active components and PPARα-ligand-binding domain （LBD）. ResultsCompared with the model group， the positive control group and 200 and 400 mg·L^-1 DA groups showed prolonged paralysis time （P<0.05）， and all the treatment groups showed decreased Aβ deposition in the head （P<0.01）. DA within the concentration range of 50-500 mg·L^-1 did not affect the viability of BV2 cells. In addition， DA enhanced the autophagy flux （P<0.05）， up-regulated the mRNA levels of beclin1， Atg5， LAMP2， and CLN2 （P<0.05， P<0.01）， promoted the nuclear translocation of TFEB （P<0.05）， increased LAMP2 expression and autophagy flux （P<0.05， P<0.01）， and enhanced the transcriptional activities of PPARα and TFEB （P<0.01）. The positive control group and 200 and 400 mg·L^-1 DA groups showed enhanced fluorescence intensity of PPARα in the BV2 nucleus （P<0.01）. UPLC-MS detected nine known compounds of DA， from which 8 active components of DA were screened out. The docking results suggested that a variety of components in DA could bind to PPARα-LBD and form stable hydrogen bonds. ConclusionDA may reduce the pathological changes in AD by regulating the PPARα-TFEB pathway.

MethodsThe safety of all children who received FLK from 29 institutions in 12 provinces between January 21，2021 and December 25，2021 was evaluated through prospective centralized surveillance and a nested case control study. ResultsA total of 3 035 juveniles were included. There were 29 research centers involved，which are distributed across 12 provinces，including one traditional Chinese medicine （TCM） hospital and 28 general hospitals. The average age among the juveniles was （4.77±3.56） years old，and the average weight was （21.81±12.97） kg. Among them，119 cases （3.92%） of juveniles had a history of allergies. Acute bronchitis was the main diagnosis for juveniles，with 1 656 cases （54.46%）. FLK was first used in 2 016 cases （66.43%），and 142 juvenile patients had special dosages，accounting for 4.68%. Among them，92 adverse drug reactions （ADRs） occurred，including 73 cases of gastrointestinal system disorders，10 cases of metabolic and nutritional disorders，eight cases of skin and subcutaneous tissue diseases，two cases of vascular and lymphatic disorders，and one case of systemic diseases and various reactions at the administration site. The manifestations of ADRs were mainly diarrhea，stool discoloration，and vomiting，and no serious ADRs occurred. The results of multi-factor analysis indicated that special dosages （the use of FLK）［odds ratio （OR） of 2.642， 95% confidence interval （CI） of 1.105-6.323］，combined administration： spleen aminopeptide （OR of 4.978， 95%CI of 1.200-20.655），and reason for combined administration： anti-infection （OR of 1.814， 95%CI of 1.071-3.075） were the risk factors for ADRs caused by FLK. Conclusion92 ADRs occurred among 3 035 juveniles using FLK. The incidence of ADRs caused by FLK was 3.03%，and the severity was mainly mild or moderate. Generally，the prognosis was favorable after symptomatic treatment such as drug withdrawal or dosage reduction，suggesting that FLK has good clinical safety.

Objective Nowadays, radioactive xenon isotopes, including ^131mXe, ^133mXe, ¹³³Xe, and ¹³⁵Xe, are primarily released into the atmosphere through various reactor operation and major accidents of reactors. To improve the online monitoring capability of xenon in nuclear facilities and their gaseous effluents, a highly sensitive online xenon monitoring system was developed to monitor, warn, and alarm the activity concentration of radioactive xenon. Methods The online monitoring system for radioactive xenon gas in nuclear facilities was established using xenon membrane separation and concentration, xenon high-efficiency selective adsorption, and low-background gamma-ray spectrometry analysis methods. Results Under the operation mode of one-hour sampling and one-hour measuring, the minimum detectable activity concentration of the radioactive xenon online monitoring system for ¹³³Xe was approximately (1.43 ± 0.03) Bq/m³. Conclusion This system can be effectively used for online monitoring of xenon activity concentration in nuclear facilities such as nuclear power plants and isotope production reactors, as well as in gaseous effluents. It helps improve the safety level of personnel, the environment, and nuclear facilities.

Objective To investigate the separation efficiency of three physical separation methods for gaseous ¹⁴C, namely membrane separation, adsorption separation, and low-temperature separation, to screen for the optimal separation method, and to provide a reference for the separation and enrichment of ¹⁴CO₂ in online monitoring of ¹⁴C. Methods The experimental plan was designed, and three devices were constructed for separation and purification experiments. The purity, recovery rate, and separation time of CO₂ separated by the three methods were analyzed. Results All the three methods achieved the separation of CO₂. Under certain conditions, 20 mL of sample gas was obtained. The separation time of membrane separation method was 0.5 hour, CO₂ gas with a sample purity of 0.0486%-0.0488%VOL was obtained, and the recovery rate was only 2.5%−12.7%. The separation time of MOF material adsorption separation method was 24−30 hours, CO₂ gas with a sample purity of 20.2%−47.5%VOL was obtained, and the recovery rate was 57.3%−63.2%. The separation time of low-temperature separation method was 3 hours, CO₂ gas with a sample purity of 96.0%−99.8%VOL was obtained, and the recovery rate was 81.5%−92.5%. Conclusion The purity and recovery rate of CO₂ with low-temperature separation method were higher compared to membrane separation method and MOF material adsorption separation method. The separation time of low-temperature separation method was moderate. The low-temperature separation method can provide a reference for the enrichment technology of ¹⁴C in the rapid measurement of gaseous ¹⁴C effluent.

Objective To analyze the activity of serum aldehyde dehydrogenase 2(ALDH2)and catalase(CAT)in patients with type 2 diabetes mellitus(T2DM)complicated with diabetic retinopathy(DR),and to explore its clinical diagnostic value.Methods A total of 206 T2DM patients in this hospital from April 2020 to November 2021 were selected and divided into T2DM group(T2DM group,n=103)and T2DM combined with DR group(T2DM+DR group,n=103)according to the presence or absence of retinopathy.Another 103 physical examination healthy people during the same period in the hospital were selected as the control group.Serum ALDH2 and CAT activities were measured.Pearson correlation analysis was used to analyze the rela-tionship between serum ALDH2,CAT and glycosylated hemoglobin,triglyceride,fasting blood glucose(FBG),1 h postprandial blood glucose(1 hPG)and insulin resistance index(HOMA-IR)in T2DM patients with DR.Multivariate Logistic regression was used to analyze the influencing factors of T2DM with DR.Re-ceiver operating characteristic(ROC)curve was used to analyze the clinical diagnostic value of serum ALDH2 and CAT for T2DM with DR.Results The serum ALDH2 and CAT activities were gradually decreased in the control group,T2DM group and T2DM+DR Group(P＜0.05).Multivariate Logistic regression analysis showed that glycosylated hemoglobin,1 hPG,HOMA-IR,duration of diabetes,ALDH2 and CAT activity were the influencing factors of T2DM patients with DR(P＜0.05).Pearson correlation analysis showed that the levels of ALDH2 and CAT were negatively correlated with glycosylated hemoglobin,triglyceride,FBG,1 hPG and HOMA-IR in T2DM patients with DR(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of ALDH2 combined with CAT in the diagnosis of T2DM patients with DR was significantly higher than AUC of ALDH2 alone(Z=2.563,P=0.010)and CAT alone(Z=1.984,P=0.047).Conclusion The serum ALDH2 and CAT activities are decreased in T2DM patients with DR.The combined detection of AL-DH2 and CAT has a high diagnostic value for T2DM patients with DR.

Objective:To explore the protective mechanism of Xuebijing injection (referred to as Xuebijing) on sepsis-associated acute respiratory distress syndrome (ARDS).Methods:① Animal experiments: 100 mice were randomly(random number) divided into 4 groups, including sham operation (Sham) group, cecal ligation and puncture (CLP) group, CLP+low-dose Xuebijing (L-XBJ) group, and CLP+high-dose Xuebijing (H-XBJ) group. The survival rate, lung histological changes, lung wet/dry (W/D) ratio, cell count and protein concentration in bronchoalveolar lavage fluids (BALF), inflammatory factors levels in serum, oxidative stress indicators, cell apoptosis, and key proteins of HIF-1α/p38 MAPK/NF-κB signaling pathway were measured. ② Cell experiments: Mouse alveolar macrophages (MH-S) were cultured in vitro and divided into 6 groups, including control (Con) group, lipopolysaccharide (LPS) group, LPS+L-XBJ group, and LPS+H-XBJ group, LPS+H-XBJ+ dimethyloxallyl glycine (DMOG, HIF-1α activator) group, LPS+H-XBJ+ 2-methoxyestradiol (2ME2, HIF-1α inhibitor) group. The effects of Xuebijing on inflammatory factors, oxidative stress, and cell apoptosis and their relationship with HIF-1α/p38 MAPK/NF-κB signaling pathway were detected.Results:Xuebijing increased the survival rate of mice with sepsis-associated ARDS, relieved lung tissue damage [lung injury score: CLP group (8.778±0.588), CLP+L-XBJ group (5.833±0.310), and CLP+H-XBJ group (4.750±0.246)], alleviated lung W/D ratio, and decreased pneumonia cell infiltration and protein exudation (all P<0.05). Additionally, Xuebijing treatment also diminished the expression of inflammatory factors (TNF-α, IL-1β, and IL-6), intracellular reactive oxygen species (ROS) accumulation, malondialdehyde (MDA) formation, superoxide dismutase (SOD) depletion, and cell apoptosis in LPS-induced MH-S cells and CLP-induced sepsis-associated ARDS mice (all P<0.05). Furthermore, mechanistic investigation further clarified the effects of Xuebijing on inflammation, oxidative stress, and cell apoptosis through the HIF-1α/p38 MAPK/NF-κB signaling pathway. Conclusions:Xuebijing can exert anti-inflammatory, anti-oxidative, and anti-apoptotic effects by suppressing the HIF-1α/p38 MAPK/NF-κB signaling pathway, thereby conferring protection against sepsis-associated ARDS.

Objective To construct a model for predicting the benign and malignant risk of the patients with gastric diseases using con-ventional laboratory indicators such as tumor markers,blood routine,and coagulation indicators,and validate its predictive value.Methods The medical records of patients with gastric diseases who visited the First Affiliated Hospital of Guangzhou Medical Univer-sity from January 2018 to January 2023 were analyzed retrospectively.According to the pathological results,the patients were divided into the gastric cancer(GC)group(n=134)and chronic non-atrophic gastritis(CNAG)group(n=298).Their routine test data such as serum and whole blood tests were collected.The statistical analysis was conducted using the R 4.2.3 software,and a model for pre-dicting the risk of GC was constructed and validated.Results A model for predicting the risk of GC was constructed successfully using the Logistic regression analysis,which included D-dimer,carcinoembryonic antigen(CEA),carbohydrate antigen 72-4(CA72-4)and hemoglobin(Hb).A visual nomogram was plotted as the final prediction model.The areas under the receiver operating characteristic(ROC)curve(AUCROC)of the model in the training and testing sets were 0.809(95%CI:0.754-0.864)and 0.808(95%CI:0.724-0.892),respectively.The sensitivity and specificity of the model were 58.5%and 93.3%,respectively,indicating that it had good pre-dictive ability.Conclusion The model for predicting the malignant risk of patients with gastric diseases constructed using routine tes-ting indicators has good accuracy and can effectively predict the risk of gastric disease transforming into gastric cancer.It helps to find early gastric cancer patients in clinical practice and take targeted prevention and intervention measures.
