ObjectiveTo investigate the mechanism of salt processing of Psoraleae Fructus （PF） through modern analytical techniques and biotechnology， focusing on its effects related to hepatotoxicity and anti-osteoporosis activity. MethodsThe zebrafish model was utilized to evaluate the impact of PF and salt-processed Psoraleae Fructus （SPF） on the hepatotoxicity （using 134.17 ， 178.89， 268.34 mg·L^-1 as low， medium， and high dose groups of PF， 135.04， 180.06， 270.08 mg·L^-1 as low， medium， and high dose groups of SPF， respectively） and anti-osteoporotic activity （using 33.54 ， 67.08 and 134.17 mg·L^-1 as low， medium， and high dose groups of PF， 33.76， 67.52， 135.04 mg·L^-1 as low， medium， and high dose groups of SPF， respectively）， which was using alizarin red skull staining of zebrafish as an indicator of different batches of PF. The specific dosage of a batch of PF was taken as an example. Then ultra-performance liquid chromatography-quadrupole-time of flight-mass spectrometry（UPLC-Q-TOF-MS） analysis was employed to identify the chemical composition of PF before and after salt processing， and PCA， OPLS-DA， and independent sample t-test were used to elucidating the compositional changes associated with the effects of salt processing on hepatotoxicity and anti-osteoporosis activity. ResultsUnder specific conditions， PF induced notable hepatotoxicity in zebrafish while simultaneously demonstrating protective effect against prednisolone-induced osteoporosis. In comparison to PF， SPF showed alleviated hepatotoxicity while retaining significant anti-osteoporosis activity. UPLC-Q-TOF-MS analysis revealed that after salt processing， the overall chemical composition of PF showed a downward trend， with 69 components showing a decrease in content， represented by psoralen， and 13 components showing an increase， represented by 4′-O-methyl psoralen B. Further multivariate statistical analysis revealed 11 key differential components before and after salt processing of PF， including psoralen and bakuchiol. ConclusionSalt processing effectively diminishes hepatotoxicity without impairing therapeutic efficacy against osteoporosis of PF， which may be related to the compositional changes before and after salt processing of PF and provides key evidence to reveal the scientific significance of salt processing of PF.

Objective To evaluate the cost-effectiveness of toripalimab plus axitinib compared to sunitinib in the first-line treatment of advanced renal cell carcinoma patients.Methods Based on the RENOTORCH trial,constructed a partitioned survival model to evaluate the long-term costs and health outcomes of toripalimab plus axitiniband sunitinib in the first-line treatment of advanced renal cell carcinoma(RCC)patients from the Chinese healthcare system perspective.The cycle length of the model was 3weeks,simulating the total cost,quality adjusted life years(QALYs),and incremental cost-effectiveness ratio(ICUR)for patients over 25 years.The costs were derived from the average bidding price of Yaozhi database in 2023 and published literature.The health state utility values were derived from clinical trials.The discount rate was 5%,and the willingness to pay(WTP)threshold was 3 times the per capita gross domestic product(GDP)in 2022.One-way and probability sensitivity analyses were used to test the robustness of the model.Results Based on the progression free survival(PFS)evaluated by the Independent Review Committee(IRC)and Investigator(IA),the ICUR values were 239 436.39 yuan/QALY and 175 440.39 yuan/QALY,respectively,both lower than the WTP threshold.One-way sensitivity analysis showed that the health state utility values of PFS status and the price of axitinib had a significant impact on the model.Probability sensitivity analysis showed that the probability of toripalimab plus axitinib being cost-effective was 63.64%and 98.03%according to the IRC and IA assessments,respectively.Conclusion Toripalimab plus axitinib was cost-effective in the first-line treatment of advanced RCC patients.

AIM:To investigate the effects of puerarin(PU)on fecal metabolomics in atherosclerosis(AS)model mice.METHODS:Apolipoprotein E gene knockout(ApoE-/-)mice were fed a high-fat,high-cholesterol diet to es-tablish an AS model.The mice were randomly divided into control,model,and PU treatment groups,with five mice in each group.Body weight changes were recorded weekly.After 12 weeks,plasma inflammatory cytokines,lipid profiles,and aortic plaque area were measured,and fecal metabolomic analysis was performed using untargeted metabolomics.RE-SULTS:(1)The high-fat,high-cholesterol diet successfully induced the AS model,with significant increases in body weight(P<0.01),plasma levels of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and IL-1β(P<0.01),as well as higher levels of low-density lipoprotein cholesterol(LDL-C),total cholesterol(TC),and triglycerides(TG),and reduced levels of high-density lipoprotein cholesterol(HDL-C)(P<0.01).The plaque area in both the whole aorta and the aortic sinus was significantly increased(P<0.01).(2)PU treatment significantly reduced body weight(P<0.05)and inflammatory cytokine levels(P<0.01),and improved lipid metabolism disorders.Specifically,TC,TG,and LDL-C lev-els significantly decreased(P<0.05 or P<0.01),while HDL-C levels significantly increased(P<0.01).In addition,the plaque area in both the whole aorta and the aortic sinus was significantly reduced in the PU-treated group(P<0.01).(3)Metabolomic analysis showed that PU regulated the levels of L-valine,L-phenylalanine,and L-histidine,restoring abnor-mal amino acid metabolism pathways.Additionally,PU downregulated abnormal levels of phosphatidylcholine and ce-ramide,promoting lipid metabolism balance.PU also modulated bile acid metabolism and oxidative stress mechanisms,improving purine and pyrimidine metabolism and related energy metabolism pathways.CONCLUSION:PU significantly ameliorates metabolic abnormalities in AS mouse models by regulating lipid metabolism,amino acid metabolism,bile acid metabolism,and gut microbiota-related metabolic pathways.

Objective:This meta-analysis compares the postoperative outcomes of the double-flap technique (DFT) versus esophagogastrostomy (EG), jejunal interposition (JI), double-tract reconstruction (DTR), and gastric tube anastomosis (GTA) following proximal gastrectomy for gastric cancer.Methods:Prospective and retrospective studies published from database inception until June 2025 were retrieved from PubMed, Embase, Web of Science, Scopus, CNKI, and Wanfang databases. Studies reporting at least one predefined outcome with extractable data were included. Outcomes of interest consisted of incidence of gastroesophageal reflux, overall postoperative complications, anastomotic leakage, anastomotic stenosis, and digestive reconstruction time. Two investigators independently performed literature screening, data extraction, and quality assessment. Randomized controlled trials (RCTs) were evaluated with the Cochrane ROB 2.0 tool, retrospective cohort studies with the Newcastle-Ottawa Scale (NOS), and single-arm studies with the JBI critical appraisal tool. Dichotomous outcomes were pooled using risk ratios (RRs), and continuous variables were summarized with standardized mean differences (SMDs), using fixed- or random-effects models based on I2 statistics. Publication bias was assessed via funnel plots and Egger's test.Results:A total of 55 studies published between 2007 and 2025 were included, comprising 5 RCTs and 50 retrospective studies. Among 4,380 patients, 732 underwent EG, 454 GTA, 1,480 DTR, 468 JI, and 1,246 DFT. Quality assessment indicated that all except six retrospective cohort studies (rated as moderate quality) were of high quality or had low risk of bias. Among the five reconstruction methods, DFT showed the lowest incidence of gastroesophageal reflux (6.6%, 82/1,246) and overall postoperative complications (11.6%, 144/1,246). JI had the lowest rate of anastomotic leakage (1.3%, 6/468), followed by DFT (1.4%, 18/1,246), and DTR had the lowest rate of anastomotic stenosis (2.4%, 36/1,480), followed by DFT (7.5%, 94/1,246). DFT required the longest operative time for reconstruction ([141.2 ± 597.6] minutes), and DTR required the shortest ([50.1 ± 39.0] minutes). Compared to EG, DFT was associated with a significantly lower risk of gastroesophageal reflux (RR=0.13 ,95%CI: 0.03-0.55, P = 0.01), and no significant differences were observed in overall complications (RR=0.98, 95%CI: 0.55-1.74, P = 0.93), anastomotic leakage (RR = 0.81, 95%CI: 0.04-18.43, P = 0.90), or anastomotic stenosis (RR = 0.75, 95%CI: 0.09-6.39, P = 0.79). Compared to JI, DFT showed no significant differences in gastroesophageal reflux (RR = 0.36, 95%CI: 0.10-1.25, P=0.11), overall complications (RR=2.06, 95%CI: 0.30-14.11, P=0.46), anastomotic leakage (RR=2.05, 95%CI: 0.26-16.18, P=0.49), or anastomotic stenosis (RR=0.83, 95%CI: 0.10-7.17, P=0.87). Similarly, compared to DTR, DFT had a lower risk of overall complications (RR=0.70, 95%CI: 0.50-0.98, P=0.04) but a longer reconstruction time (SMD: 2.55, 95%CI: 0.31-4.79, P=0.03). No significant differences were found in gastroesophageal reflux (RR = 0.68, 95%CI: 0.35-1.30, P=0.24), anastomotic leakage (RR=0.59, 95%CI: 0.16-2.17, P=0.43), or anastomotic stenosis (RR=2.44 , 95%CI: 0.44-13.64, P=0.31). Compared to GTA, DFT was associated with a significantly lower risk of gastroesophageal reflux (RR = 0.53, 95%CI: 0.33-0.88, P=0.01), but again there were no significant differences in overall complications (RR = 0.69, 95%CI: 0.41-1.16, P=0.16), anastomotic leakage (RR = 0.25, 95%CI: 0.03-2.14, P=0.21), or anastomotic stenosis (RR=0.65, 95%CI: 0.24-1.76, P=0.40). No significant publication bias was detected in the analysis (Egger's test P>0.05). Conclusions:Among the five common anastomotic methods after proximal gastrectomy, DFT demonstrates superior anti-reflux efficacy, outperforming EG and GTA in particular in preventing gastroesophageal reflux. DFT also exhibits a lower overall complication risk compared with DTR but maintains anastomotic safety comparable with that of the other techniques.

Objective: The treatment of asymmetric maxillary hypoplasia and dental crowding secondary to unilateral cleft lip and palate (UCLP) is often challenging.This study introduced an asymmetric tooth-borne distractor in anterior maxillary segmental distraction osteogenesis and used three-dimensional finite element analysis to evaluate its potential for clinical application in cases of asymmetrical maxillary hypoplasia. Methods: A cone-beam computed tomography scan of a late adolescent with UCLP was used to construct a three-dimensional finite element model of the teeth and maxillary structures. An asymmetric distractor model was used to simulate conventional distraction osteogenesis and asymmetric distraction osteogenesis (ADO) to evaluate the resultant stress distribution and displacement. Results: Postoperatively, both distraction methods resulted in anterior maxillary segment advancement with a slight upward movement. ADO yielded a greater increase in the dental arch length on the cleft side and induced rotation of the anterior maxillary segment, potentially improving midline deviation. Both methods showed similar stress distributions, with higher stress concentrations on the cleft side. Conclusions ADO may offer clinical advantages in correcting asymmetrical maxillary hypoplasia in patients with UCLP by facilitating asymmetrical expansion and rotation of the maxilla. Further research is needed to generalize these findings to other clinical presentations.

Hypercoagulable state (HCS) after kidney transplantation is one of the common and serious complications in kidney transplant recipients, which has attracted increasing attention in recent years. HCS refers to the abnormal and excessive activation of blood coagulation function, leading to the increased risk of thrombosis. After kidney transplantation, the combined effects of hemodynamic changes, surgical trauma and severe rejection increase the incidence of HCS, not only raising the risk of thrombosis but also potentially causing graft failure and affecting the postoperative survival rate of patients. This article reviews the influencing factors, clinical manifestations, diagnostic methods and preventive strategies of HCS after kidney transplantation, aiming to provide a theoretical basis for optimizing perioperative management and improving the prognosis of patients.
