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.

ObjectiveTo analyze the research hotspots and development trends in the field of spinal cord stimulation (SCS) for spinal cord injury (SCI). MethodsLiterature about SCS for SCI was retrieve from the Web of Science (WOS) Core Collection database, with a time range from January, 1999 to July, 2025. VOSviewer 1.6.20 and CiteSpace 6.4.R2 were used to analyze the annual publication volume, countries, authors, institutions, journals and keywords. ResultsA total of 636 literatures were included. From 1999 to 2025, the overall publication trend in this field showed an upward trajectory, with recent years fluctuating but tending to stabilize. The country with the most publications was the United States (429 papers), followed by Russia (98 papers) and China (70 papers). The institution with the highest number of publications was the University of California, Los Angeles (76 papers), the author with the most publications was V. Reggie Edgerton (70 papers), and the journal with the most publications was Journal of Clinical Medicine (31 papers). The most frequently cited study focused on exploring the combination of epidural spinal cord stimulation with task-specific training to restore motor function in patients with complete SCI. Keyword analysis showed that the research hotspots in this field were mainly focused on neuroregulation mechanisms, recovery of motor and autonomic nervous dysfunction, artificial intelligence, closed-loop stimulation and brain-computer interface technology innovations. In recent years, the research focus gradually shifted from basic mechanisms to personalized and precise multifunctional rehabilitation strategies. ConclusionThe field of SCS for SCI has undergone phases of basic mechanism exploration and clinical application expansion. Current research hotspots and future trends focus primarily on the development of new stimulation paradigms and combined innovative technologies.

ObjectiveTo observe the clinical efficacy and safety of Tangning Tongluo tablets in the treatment of nonproliferative diabetic retinopathy （DR）. MethodsFourteen research centers participated in this study， which spanned a time interval from September 2021 to May 2023. A total of 240 patients with nonproliferative DR were included and randomly assigned into an observation group （120 cases） and a control group （120 cases）. The observation group was treated with Tangning Tongluo tablets， and the control group with calcium dobesilate capsules. Both groups were treated for 24 consecutive weeks. The vision， DR progression rate， retinal microhemangioma， hemorrhage area， exudation area， glycosylated hemoglobin （HbA1c） level， and TCM syndrome score were assessed before and after treatment， and the safety was observed. ResultsThe vision changed in both groups after treatment （P<0.05）， and the observation group showed higher best corrected visual acuity （BCVA） than the control group （P<0.05）. The DR progression was slow with similar rates in the two groups. The fundus hemorrhage area and exudation area did not change significantly after treatment in both groups， while the observation group outperformed the control group in reducing the fundus hemorrhage area and exudation area. There was no significant difference in the number of microhemangiomas between the two groups before treatment. After treatment， the number of microhemangiomas decreased in both the observation group （Z=-1.437， P<0.05） and the control group （Z=-2.238， P<0.05）， and it showed no significant difference between the two groups. As the treatment time prolonged， the number of microhemangiomas gradually decreased in both groups. There was no significant difference in the HbA1c level between the two groups before treatment. After treatment， the decline in the HbA1c level showed no significant difference between the two groups. The TCM syndrome score did not have a statistically significant difference between the two groups before treatment. After treatment， neither the TCM syndrome score nor the response rate had significant difference between the two groups. With the extension of the treatment time， both groups showed amelioration of TCM syndrome compared with the baseline. ConclusionTangning Tongluo tablets are safe and effective in the treatment of nonproliferative DR， being capable of improving vision and reducing hemorrhage and exudation in the fundus.

It is believed that patients with cirrhotic ascites exhibit a pathological mechanism characterized by the decline of healthy qi and the accumulation of pathogenic factors. Clinically， treatment should be based on the theory of tonification and purging， with a staged approach distinguishing between the active phase and the remission phase. The balance between tonification and purging should be adjusted according to the progression of pathogenic and healthy actors. In the acute phase， purging should take precedence over tonification， using purging as a means of tonification to facilitate the flow of water and qi through the triple energizer. The severity of water retention， dampness， blood stasis， and heat should be carefully assessed to ensure thorough elimination of pathogenic factors while avoiding harm to healthy qi. Medication adjustments should be made once the pathogenic factors are significantly weakened. In the remission phase， an integrated approach combining both tonification and purging should be adopted， incorporating purging within tonification to clear residual pathogens and prevent recurrence. Concurrently， proactive treatment of the underlying disease is essential to achieve complete recovery and prevent the recurrence of ascites.

Objective To observe and analyze the clinical efficacy and safety of carvedilol combined with dual-wavelength pulsed dye laser in the treatment of rosacea.Methods A retrospective analysis was per-formed on 50 patients with rosacea mainly characterized by flushing,erythema,and telangiectasia who were treated with dual-wavelength pulsed dye laser in the Department of Dermatology of this hospital from October 2023 to October 2024.They were divided into the observation group and the control group according to differ-ent treatment methods,with 25 cases in each group.The control group received dual-wavelength pulsed dye la-ser treatment,while the observation group received carvedilol combined with dual-wavelength pulsed dye laser treatment.The clinical erythema assessment(CEA)scale and physician global assessment(PGA)were used to evaluate the efficacy of the two groups,and the occurrence of adverse reactions was recorded.Results After treatment,the CEA scores of both groups were lower than those before treatment.The CEA score of the ob-servation group was lower than that of the control group,and the PGA score was higher than that of the con-trol group,with statistically significant differences(P<0.05).No singnifcant adverse reactions occurred in ei-ther group.Conclusion Carvedilol combined with dual-wavelength pulsed dye laser is more effective than sin-gle dual-wavelength pulsed dye laser in the treatment of rosacea,and the treatment method is safe.

Objective Through a non-inferiority trial design,to verify whether the efficacy of transcuta-neous electrical acupoint stimulation(TEAS)in intervening with nausea and vomiting after painless gastros-copy and colonoscopy was not inferior to that of ondansetron,and evaluate its effect on patient recovery.Meth-ods A total of 112 patients who experienced nausea and vomiting after painless gastroscopy and colonoscopy in the gastroscopy and colonoscopy center of the hospital from March 2022 to March 2023 were selected as the research subjects,and divided into the TEAS group(n=56)and the control group(n=56)according to the random number table method.The TEAS group received TEAS intervention,while the control group received ondansetron hydrochloride injection intervention.The non-inferiority margin was set at 10.0％.The interven-tion effective rate of nausea and vomiting after examination,as well as heart rate,blood pressure,length of stay,satisfaction,and visual analogue score(VAS)were compared between the two groups.Results The in-tervention effective rate of the TEAS group was close to that of the control group[82.4％(46/56)vs.80.4％(45/56)],risk difference(RD)=2.0％(95％CI:-9.8％to 13.8％),the lower limit of 95％CI(-9.8％)was higher than the preset cut-off value(-10.0％),and non-inferiority was established(P=0.032).Com-pared with before the examination,the heart rates of the two groups were slower,and the levels of systolic blood pressure(SEP)and diastolic blood pressure(DBP)were lower during the examination,and the differ-ences were statistically significant(P＜0.05).There was no statistically significant difference in the two groups of heart rate,SBP,DBP,length of stay[(69.9±14.2)min vs.(75.3±22.8)min],satisfaction score(9.8±0.6 vs.9.2±2.0),VAS(1.5±0.5 vs.2.1±0.5,P＞0.05).Conclusion The efficacy of TEAS in in-tervening with nausea and vomiting after painless gastroscopy and colonoscopy is not inferior to that of ondan-setron.

Objective To investigate the labeling of dialysis-related information in the instructions of drugs for systemic use in patients with end-stage renal disease undergoing hemodialysis,and to provide reference for further standardization and im-provement of drug instructions.Methods Collected the information on pharmacokinetics and drug dose adjustment in hemodi-alysis patients with end-stage renal disease from the instructions of chemicals and biologics used systemically in XuanWu hospital's formulary from January to March 2023.Classified and compared the labeling rates of the corresponding information of the originally developed drugs and generic drugs,imported drugs and domestic drugs;Drugs eliminated by non-renal route,or with mo-lecular weight≥5 000,or binding rate of plasma protein ≥ 60％,or drug distribution volume＞360L were classified as"non-dialysis group",and other drugs were classified as"dialysis group",compared the labeling rate of corresponding information of drugs in"dialysis group"and"non-dialysis group";and compared the labeling rate and content with relevant information in Lexicomp and Micromedex.Results Among the 930 drug instructions,the labeling rates of drug dialysis clearance,drug adjustment,and ex-plicit drug adjustment plan were 16.67％,25.16％,and 24.52％.There was no significant difference in the labeling rate of dialysis-related information between original and generic drugs,and imported and domestic drugs.There was a significant difference in the labeling rate of dialysis-related information between the"dialyzable group"and the"non-dialyzable group"(P＜0.01).The differ-ence in the labeling rate of dialysis related information between the investigated drug instructions and the corresponding drugs in Lexicomp or Micromedex was statistically significant(P＜0.01).Conclusion Attention should be paid to the lack of informa-tion and unclear labeling of hemodialysis patients with end-stage renal disease in the drug instructions by relevant departments.

Background::Hepatitis B poses a heavy burden for children in China, however, the national studies on the distributional characteristics and health care costs of children with severe hepatitis B is still lacking. This study aimed to analyze the disease characteristics, health economic effects, and medical cost for children with severe hepatitis B in China.Methods::Based on patient information in the Hospital Quality Monitoring System, cases with severe hepatitis B were divided into four groups according to age, and the etiology and symptoms of each group were quantified. The cost of hospitalization was calculated for cases with different disease processes, and severity of disease. The spatial aggregation of cases and the relationship with health economic factors were analyzed by Moran’s I analysis. Results::The total number of children discharged with hepatitis B from January 2016 to April 2022 was 1603, with an average age of 10.5 years. Liver failure cases accounted for 43.48% (697/1603) of total cases and cirrhosis cases accounted for 11.23% (180/1603). According to the grouping of disease progression, there were 1292 cases without associated complications, and the median hospitalization cost was $818.12. According to the spatial analysis, the aggregation of cases was statistically significant at the prefectural and provincial levels in 2019, 2020, and 2021 (all P <0.05). The number of severe cases was negatively correlated with gross domestic product (Moran’s I <0) and percentage of urban population (Moran’s I <0), and positively correlated with the number of pediatric beds per million population (Moran’s I >0). Conclusion::The number of severe hepatitis B cases is low in areas with high gross domestic product levels and high urban population ratios, and health care costs have been declining over the years.

Objective: To explore the longitudinal associations between dietary macronutrients and lung function in schoolaged children, so as to provide the nutritional research evidence for promoting children s lung health. Methods: In November 2021, two primary schools located in Chengdu, Sichuan Province were selected from the Southwest China Childhood Nutrition and Growth (SCCNG) cohort by a stratified cluster random sampling method, enrolling a total of 1 112 school aged children aged 8 to 13 years. At baseline, the dietary and sociodemographic characteristics of the children were assessed. One year later, the forced vital capacity (FVC) of the children was measured and converted into Z scores (FVC- Z ), while the vital capacity index (VCI) was also calculated. Generalized linear regression analysis was employed to examine the associations between dietary macronutrients and lung function, considering interactions with gender and age, followed by stratified analysis. Results: After adjusting for confounding factors, the analysis results of the generalized linear regression model showed that the carbohydrate energy ratio was negatively correlated with FVC- Z ( β =-0.02) and VCI ( β =-0.16), while the fat energy ratio showed a positive correlation with FVC- Z ( β =0.03) and VCI ( β =0.23) ( P <0.05). The protein energy ratio was positively correlated with FVC- Z ( β =0.09) and VCI ( β =0.60) specifically in girls ( P <0.05). Additionally, there was an interaction effect of age on the associations between macronutrients and lung function ( P <0.01); in children aged 8-9 and 10-11, the carbohydrate energy supply ratio was negatively correlated with FVC- Z ( β =-0.04, -0.03) and VCI ( β =-0.29, -0.21), and fat energy supply ratio was positively correlated with FVC- Z ( β =0.07, 0.05) and VCI ( β =0.46, 0.32) ( P <0.05). Conclusions There are age and sex differences in the association of dietary macronutrients with lung function, with a low carbohydrate, high fat diet promoting lung function in children. Additionally, protein intake appears to have a positive influence on the lung function of girls. The early school age period may represent a critical window for dietary interventions aimed at promoting lung health.

Atherosclerosis is a complex pathological condition resulting from lipid deposition， chronic inflammatory responses， and fibrosis， with a prolonged disease course and multifactorial etiology. Based on the traditional Chinese medicine （TCM） theory of accumulation syndrome， atherosclerosis can be classified under this category， with its pathogenesis involving phlegm， blood stasis， deficiency， and accumulation. This paper proposed a stage-based intervention strategy using the four therapeutic principles of "attacking， supplementing， dispersing， dissipating"， and divided into six stages based on the pathological progression， including the stage of accumulation before formation， the stage of accumulation already formed， the stage of nucleus accumulation， the stage of nucleus accumulation decay， the stage of nucleus accumulation consolidation， and the stage of severe stenosis of nucleus. At different stages， the intervention focuses on reinforcing healthy qi and consolidating the root， tonifying the kidneys and spleen， dispersing and removing turbidity， removing phlegm stagnation， promoting qi circulation， dispersing accumulations and removing stasis， attacking accumulation and expelling stasis， directing the turbid downward and dispersing accumulation， and treatment would be adjusted based on specific symptoms， which provides a theoretical framework for the prevention and treatment of atherosclerosis with TCM.
