This study employed the "disease-medicine-dose" pattern to mine the medication rules of traditional Chinese medicine(TCM) prescriptions containing Astragali Radix in ancient Chinese medical books, aiming to provide a scientific basis for the clinical application of Astragali Radix and the development of new medicines. The TCM prescriptions containing Astragali Radix were retrieved from databases such as Chinese Medical Dictionary and imported into Excel 2020 to construct the prescription library. Statical analysis were performed for the prescriptions regarding the indications, syndromes, medicine use frequency, herb effects, nature and taste, meridian tropism, dosage forms, and dose. SPSS statistics 26.0 and IBM SPSS Modeler 18.0 were used for association rules analysis and cluster analysis. A total of 2 297 prescriptions containing Astragali Radix were collected, involving 233 indications, among which sore and ulcer, consumptive disease, sweating disorder, and apoplexy had high frequency(>25), and their syndromes were mainly Qi and blood deficiency, Qi and blood deficiency, Yin and Yang deficiency, and Qi deficiency and collateral obstruction, respectively. In the prescriptions, 98 medicines were used with the frequency >25 and they mainly included Qi-tonifying medicines and blood-tonifying medicines. Glycyrrhizae Radix et Rhizoma, Angelicae Sinensis Radix, Ginseng Radix et Rhizoma, Atractylodis Macrocephalae Rhizoma, and Citri Reticulatae Pericarpium were frequently used. The medicines with high frequency mainly have warm or cold nature, and sweet, pungent, or bitter taste, with tropism to spleen, lung, heart, liver, and kidney meridians. In the treatment of sore and ulcer, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to promote granulation and heal up sores. In the treatment of consumptive disease, Astragali Radix was mainly used with the dose of 37.30 g and combined with Ginseng Radix et Rhizoma to tonify deficiency and replenish Qi. In the treatment of sweating disorder, Astragali Radix was mainly used with the dose of 3.73 g and combined with Glycyrrhizae Radix et Rhizoma to consolidate exterior and stop sweating. In the treatment of apoplexy, Astragali Radix was mainly used with the dose of 7.46 g and combined with Glycyrrhizae Radix et Rhizoma to dispell wind and stop convulsions. Astragali Radix can be used in the treatment of multiple system diseases, with the effects of tonifying Qi and ascending Yang, consolidating exterior and stopping sweating, and expressing toxin and promoting granulation. According to the manifestations of different diseases, when combined with other medicines, Astragali Radix was endowed with the effects of promoting granulation and healing up sores, tonifying deficiency and Qi, consolidating exterior and stopping sweating, and dispelling wind and replenishing Qi. The findings provide a theoretical reference and a scientific basis for the clinical application of Astragali Radix and the development of new medicines.

To elucidate the mechanism by which steaming affects the quality of Curcuma kwangsiensis root tubers, methods such as LSCM, RVA, dual-wavelength spectrophotometry, LF-NMR, and LC-MS were employed to qualitatively and quantitatively detect changes in starch gelatinization characteristics, water distribution, and material composition of C. kwangsiensis root tubers under different steaming durations. Based on multivariate statistical analysis, the correlation between differences in gelatinization parameters, water distribution, and terpenoid material composition was investigated. The results indicate that steaming affects both starch gelatinization and water distribution in C. kwangsiensis. During the steaming process, transformations occur between amylose and amylopectin, as well as between semi-bound water and free water. After 60 min of steaming, starch gelatinization and water distribution reached an equilibrium state. The content of amylopectin, the amylose-to-amylopectin ratio, and parameters such as gelatinization temperature, viscosity, breakdown value, and setback value were significantly correlated(P≤0.05). Additionally, the amylose-to-amylopectin ratio was significantly correlated with total free water and total water content(P≤0.05). Steaming induced differences in the material composition of C. kwangsiensis root tubers. Clustering of primary metabolites in the OPLS-DA model was distinct, while secondary metabolites were classified into 9 clusters using the K-means clustering algorithm. Differential terpenoid metabolites such as(-)-α-curcumene were significantly correlated with zerumbone, retinal, and all-trans-retinoic acid(P<0.05). Curcumenol was significantly correlated with isoalantolactone and ursolic acid(P<0.05), while all-trans-retinoic acid was significantly correlated with both zerumbone and retinal(P<0.05). Alpha-tocotrienol exhibited a significant correlation with retinal and all-trans-retinoic acid(P<0.05). Amylose was extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and α-tocotrienol(P<0.05). Amylopectin was significantly correlated with zerumbone(P<0.05) and extremely significantly correlated with(-)-α-curcumene, curcumenol, zerumbone, retinal, all-trans-retinoic acid, and 9-cis-retinoic acid(P<0.01). The results provide scientific evidence for elucidating the mechanism of quality formation of steamed C. kwangsiensis root tubers as a medicinal material.

Objective:To analyze the relationship between the optimal surgical margin value and clinical prognosis of transoral robotic surgery（TORS） in treating human papillomavirus（HPV） -positive oropharyngeal squamous cell carcinoma. Methods:A single-center, prospective, observational cohort study was conducted, enrolling patients with early and moderated stage（≤T3 stage） oropharyngeal carcinoma undergoing TORS between July 2020 and April 2024. The proposed optimal surgical margin cutoff value for TORS was set as 2 mm. The primary objectives were to evaluate the optimal clear margin for TORS and its association with overall survival（OS） and progression-free survival（PFS）. Logistic regression was used to analyze correlations between surgical margins and clinical variables, while Cox regression models assessed the impact of surgical margins on OS and PFS. Results:A total of 90 patients（60 males, 66.7%） were included, all had squamous cell carcinoma, with a mean age of 58.0±9.0 years（range: 39-84 years） old. The 1, 2 and 3-year OS rates were 92.3%, 89.9% and 85.0%, respectively, while the 1, 2 and 3-year PFS rates were all 90.1%. For surgical margins ≤2 mm, the 1, 2 and 3-year OS rates were 80.8%, 69.3% and 69.3%, respectively, and PFS rates were 77.9% across three time points. For surgical margins>2 mm, the 1, 2 and 3-year OS rates were 96.5%, 96.5% and 90.6%, respectively, with PFS rates of 94.6%. Logistic regression showed no correlation between surgical margins and tumor type, T/N stage, smoking, alcohol use, or gender（P>0.05）. Cox analysis identified surgical margins>2 mm as a significant factor improving PFS（HR=0.14, 95%CI 0.02-0.90, P=0.038）. Conclusion:This systematic analysis suggests setting a 2 mm and longer as clear surgical margin for TORS. Margins>2 mm are associated with superior postoperative PFS rate and prolonged PFS time in HPV-positive oropharyngeal carcinoma patients.

Objective To explore the effect of hypoxia-inducible factor-1α(HIF-1α)inhibitor LW6 on ferroptosis in septic cardiomyopathy rats.Methods Rat septic cardiomyopathy model was prepared using cecal ligation and puncture(CLP)method.Thirty-six specific pathogen-free(SPF)6-8 weeks male SD rats were randomly divided into the sham-operated group,CLP group,CLP+solvent group,LW6 group,ferrostatin-1(Fer-1)group,and LW6+Fer-1 group.The degree of myocardial damage in each group was evaluated through hematoxylin-eosin stai-ning and detection of lactate dehydrogenase and creatine kinase content in cardiac tissue.Myocardial mitochondrial damage was observed by transmission electron microscopy.Ferroptosis level was determined by detecting iron ion concentration,reduced glutathione,malondialdehyde,and reactive oxygen species.Protein expression levels of HIF-1α,solute carrier family 7 member 11(SLC7A11),and glutathione peroxidase 4(GPX4)in cardiac tissue were detected by Western blotting.Results Compared with the CLP group and the CLP+solvent group,the LW6 group could ameliorate myocardial damage,alleviate mitochondrial damage,inhibit ferroptosis-related indicators(all P＜0.05),reduce HIF-1α protein expression levels(P＜0.05),and enhance SLC7A11 and GPX4 protein expression levels(both P＜0.05).Conclusion LW6 decreases HIF-1α expression and ferroptosis levels through the SLC7A11/GPX4 pathway,and ameliorates sepsis-induced cardiomyopathy.

Objective To investigate the effect and mechanism of andrographolide(AG)on lipopolysaccharide(LPS)-induced ferroptosis in renal tubular epithelial cells(HK-2 cells).Methods HK-2 cells were treated with LPS to simulate the in vitro HK-2 injury model of sepsis.The cells were further treated with AG of 5,10,20,40 μmol/L and randomly divided into control group,LPS group,LPS+dimethyl sulfoxide group(DMSO group),and AG group.Cell viability was detected by the CCK-8 method,and the optimal concentrations of LPS and AG were screened.Cell morphological change,the levels of kidney injury markers,including neutrophil gelatinase-associated lipocalin(NGAL),kidney injury molecule-1(KIM-1),malondialdehyde(MDA),glutathione(GSH)and reactive oxygen species(ROS),as well as the expression levels of ferroptosis regulatory proteins such as solute carrier family 7 member 11(SLC7A11),glutathione peroxidase 4(GPX4)and ferritin in each group were compared,and the pro-tective effect of AG treatment on the cells was evaluated.Results Compared with the control group,the cell viabi-lity and GSH content decreased significantly in HK-2 cells treated with 10 μg/mL LPS;cell shrinkage and adhesion ability were poor;the contents of oxidative products MDA and ROS,as well as the levels of kidney injury markers NGAL and KIM-1 increased significantly,while expression levels of SLC7A11 and GPX4 protein decreased;ferritin expression level increased;differences were all statistically significant(all P＜0.05).Compared with LPS group,the cell viability,GSH content,as well as protein expression levels of SLC7A11 and GPX4 increased significantly after AG intervention,while ferritin expression level decreased,differences were all significant(all P＜0.05).MDA content,ROS fluorescence intensity,and the levels of kidney injury markers NGAL and KIM-1 decreased sig-nificantly,difference were all significant(all P＜0.05).Conclusion AG has a protective effect on LPS-induced HK-2 cell injury,possibly by activating SLC7A11/GPX4 pathway,reducing oxidative stress,up-regulating antioxi-dant enzyme activity,and alleviating ferroptosis.

Objectives:To investigate the intravascular ultrasound(IVUS)evaluated efficacy of the"L-sandwich"technique in the percutaneous coronary intervention treatment of true bifurcation lesions of coronary artery. Methods:Ninety-nine patients with true bifurcation lesions(medina type 1.1.1)of the coronary arteries were divided into the L-sandwich group(n=38),the double-stent group(n=32),and the main vessel(MV)single-stent with side branch(SB)drug-coated balloon(DCB)only group(n=29).The primary study endpoint was the loss of late lumen area(LLAL)in the MV,SB ostium and SB shaft at 12 months,and the secondary endpoints were minimum lumen area(MLA)at each site and major adverse cardiac events(MACE)at 12 months.As this is a proof-of-concept study,statistical analyses were performed in the as-treated(AT)analysis set. Results:At 12-month follow-up,there was no statistically significant difference in the MV LLAL among patients in the"L-sandwich"technique group,the double stent technique group,and the MV DES with SB DCB technique group([0.12±0.42]mm2 vs.[0.07±0.38]mm2 vs.[-0.01±0.31]mm2,P=0.419).Similarly,there was no statistically significant difference in the LLAL at the SB shaft([-0.11±0.45]mm2 vs.[-0.10±0.28]mm2 vs.[0.24±1.04]mm2,P=0.078],with the maximum LLAL observed in the double stent technique group and the minimum in the"L-sandwich"technique group([-0.48±0.78]mm2 vs.[0.45±0.64]mm2 vs.[0.14±1.37]mm2,P<0.001).The MV MLA was similar among the three groups([8.39±1.65]mm2 vs.[8.28±0.98]mm2 vs.[8.02±1.37]mm2,P=0.565),while the maximum MLA at the SB ostium was observed in the double stent technique group and the minimum in the MV DES with SB DCB group([5.08±0.74]mm2 vs.[5.63±0.80]mm2 vs.[3.57±1.35]mm2,P<0.001).In terms of MLA at the SB shaft,the"L-sandwich"technique group was similar to the double stent technique group,while the MV DES with SB DCB group exhibited the minimum MLA([5.94±0.72]mm2 vs.[5.86±0.59]mm2 vs.[3.74±1.07]mm2,P<0.001).Two patients in the double stent technique group underwent target vessel revascularization,there was no MACE in the other two groups(P=0.118). Conclusions:The"L-sandwich"technique is safe and feasible for the treatment of coronary bifurcation lesions.Compared with double-stent group,the SB ostium has a smaller LLAL at the time of review,and there is no significant difference in the MLA of each site,and the operation steps are significantly simplified.Use of the"L-sandwich"technique is associated with a better branching benefit compared with MV single-stent group.The"L-sandwich"technique could be used as a remedial procedure for severe entrapment in the setting of branching with DCB alone.

Objective The effectiveness of the BG-Trap and human-baited double net trap(HDN)methods in monitoring Aedes albopictus were compared to assess the potential use of the BG-Trap method for dengue fever vector monitoring program.These findings would also provide a reference basis for formulating more effective dengue fever prevention and control strategies.Methods The study was conducted at six outdoor monitoring sites in three cities in Jiangsu Province in August and September,following a 3-d monitoring plan.Both traps were evaluated simultaneously at three time slots each day(16:00-16:30,17:00-17:30,and 18:00-18:30).Results Both the BG-Trap and HDN methods effectively captured female Ae.albopictus.The proportion of Ae.albopictus captured by the HDN method was higher than that captured by the BG-Trap method(χ2 = 0.162,P= 0.687),with no statistically significant differences in the composition ratio of male/female between the two methods(χ2=0.162,P=0.687).The average density index of Ae.albopictus for the BG-Trap method was 7.85±5.23/h,significantly lower than that of the HDN method at 27.04±13.86/h under the same sampling sites(t = 6.73,P＜0.001).Conclusion These results suggest that the BG-Trap method is less effective than the HDN method in Ae.albopictus monitoring.Further research is required to determine the applicability of this method for dengue fever vector monitoring.

Objective: To evaluate the incidence, treatment, and survival outcomes of Swyer syndrome with gonadal non-dysgerminoma malignant germ cell tumor (MGCT-NDG). Methods: A retrospective study was performed on Swyer syndrome patients with MGCT-NDG between January 2011 and December 2022 in Peking Union Medical College Hospital to investigate their characteristics and outcomes. Results: A total of 15 patients (4.9%, 15/307) with Swyer syndrome were identified in 307 MGCT-NDG patients. The average age at diagnosis of MGCT-NDG and Swyer syndrome were (16.8±6.7) and (16.7±6.6) years, respectively. Six cases were preoperatively diagnosed as Swyer syndrome, of which 4 cases received bilateral gonadectomy with or without hysterectomy, while the other 2 cases underwent removal of gonadal tumor and unilateral gonadectomy with hysterectomy, respectively. Of the 9 patients postoperatively diagnosed as Swyer syndrome, unilateral gonadectomy, removal of gonadal tumor, and unilateral gonadectomy with hysterectomy were performed in 6 patients, 2 patients, and 1 patient, respectively. Mixed malignant germ cell tumor (MGCT;10 cases), yolk sac tumor (4 cases), and immature teratoma (1 case) were the pathological subtypes, in the descending order. There were International Federation of Gynecology and Obstetrics (FIGO) stage Ⅰ in 6 cases, stage Ⅱ in 3 cases, stage Ⅲ in 5 cases, and stage Ⅳ in 1 case, respectively. Eleven patients received reoperation for residual gonadectomy after a average delay of (7.9±6.2) months, including 8 MGCT-NDG patients and 1 gonadoblastoma patient, no tumor involved was seen in the remaining gonads in the other 2 cases. Ten patients experienced at least one recurrence, with a median event free survival of 9 months (5, 30 months), of which 2 patients received surgery only at the time of initial treatment. All patients with recurrence received surgery and combined with postoperative chemotherapy. After a median follow-up of 25 months (15, 42 months), 10 patients were disease-free, 3 patients died of the tumor, 1 died of side effects of leukemia chemotherapy, and 1 survived with disease. Conclusion: The incidence rate of Swyer syndrome in patients with MGCT-NDG is about 4.9%; timely diagnosis and bilateral gonadectomy should be emphasized to reduce the risk of reoperation and second carcinogenesis in this population.
