Fresh-cut processing constitutes a pivotal technique in the origin processing of Chinese medicinal materials， with a long history documented in multiple materia medica. In recent years， it has garnered national policy support for its ability to prevent component loss and low processing efficiency associated with traditional drying-before-cutting methods. As of August 2025， 26 provinces and municipalities nationwide have cumulatively published 789 species for fresh-cut processing. Among these， 78 were included in the 2025 edition of the Pharmacopoeia of the People's Republic of China. However， the practice continues to face common challenges and difficulties， including ambiguous scientific understanding， fragmented standards， limited quality control approaches， and poor process stability. Based on this， this paper synthesises years of research findings to systematically elucidate the core mechanisms of fresh-cut processing. These encompass alterations to herbal tissue structure during cutting， post-processing changes in constituents， and physiological-biochemical processes such as plant stress responses and shifts in endogenous enzyme activity. It also summarises influencing factors， including inherent herbal properties， cutting timing and methods， and environmental conditions like temperature， humidity， and microbial presence. Based on this overview of fresh-cutting mechanisms， subsequent research should advance in four directions：Clarifying the scientific principles of fresh-cutting， overcoming technical bottlenecks， upgrading intelligent equipment， and establishing quality standards and evaluation systems. This study provides a theoretical foundation and scientific basis for future research on fresh-cutting in traditional Chinese medicine（TCM）， promoting its deeper practical application within the industry and contributing to the high-quality development of TCM industry and the modernization of TCM.

BACKGROUND:Degenerative scoliosis is defined as a condition that occurs in adulthood with a coronal cobb angle of the spine>10° accompanied by sagittal deformity and rotational subluxation,which often produces symptoms of spinal cord and nerve compression,such as lumbar pain,lower limb pain,numbness,weakness,and neurogenic claudication.The finite element method is a mechanical analysis technique for computer modelling,which can be used for spinal mechanics research by building digital models that can realistically restore the human spine model and design modifications. OBJECTIVE:To review the application of finite element method in the etiology and treatment of degenerative scoliosis. METHODS:The literature databases CNKI,PubMed,and Web of Science were searched for articles on the application of finite element method in degenerative scoliosis published before October 2023.Search terms were"finite element analysis,biomechanics,stress analysis,degenerative scoliosis,adult spinal deformity"in Chinese and English.Fifty-four papers were finally included. RESULTS AND CONCLUSION:(1)The biomechanical findings from the degenerative scoliosis model constructed using the finite element method were identical to those from the in vivo experimental studies,which proves that the finite element method has a high practical value in degenerative scoliosis.(2)The study of the etiology and treatment of degenerative scoliosis by the finite element method is conducive to the prevention of the occurrence of the scoliosis,slowing down the progress of the scoliosis,the development of a more appropriate treatment plan,the reduction of complications,and the promotion of the patients'surgical operation.(3)The finite element method has gradually evolved from a single bony structure to the inclusion of soft tissues such as muscle ligaments,and the small sample content is increasingly unable to meet the research needs.(4)The finite element method has much room for exploration in degenerative scoliosis.

Objective To analyze the effects of intravenous tirofiban following endovascular treatment on the prognosis of patients with acute anterior circulation large vessel occlusion stroke who did not achieve successful recanalization.Methods This retrospective study included consecutive patients with acute anterior circulation ischemic stroke who underwent endovascular treatment but did not achieve successful recanalization.These patients were retrospectively enrolled from the Department of Neurology at Nanjing Jinling Hospital,Affiliated Hospital of Medical School,Nanjing University,the Second Affiliated Hospital of Soochow University,Wuhan No.1 Hospital,and Yijishan Hospital of Wannan Medical College(the First Affiliated Hospital of Wannan Medical College)between January 2015 and April 2023.Baseline and clinical data were collected including age,sex,medical history(hypertension,diabetes,atrial fibrillation,hyperlipidemia),personal history(smoking and drinking),National Institutes of Health stroke scale(NIHSS)score at admission,trial of Org 10172 in acute stroke treatment(TOAST)classification(large artery atherosclerosis,cardioembolism,or other types),Alberta stroke program early CT score(ASPECTS)on admission,intravenous thrombolysis,onset-to-puncture time(OTP),collateral circulation status(poor collaterals:American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology[ASTIN/SIR]score 0-2;good collateral:ASTIN/SIR score 3-4),procedure duration(from femoral or radial artery puncture to device removal),occlusion site,number of passes for thrombus retrieval,and post-procedural modified thrombolysis in cerebral infarction(mTICI)grade.Patients were divided into a tirofiban group and a non-tirofiban group based on whether they received post-procedural intravenous tirofiban.The primary outcome is a favorable functional outcome at 90-day since onset(modified Rankin scale[mRS]score ≤ 3).Safety outcomes included mortality at 90-day since onset(mRS score 6),any intracranial hemorrhage within 24 h post-procedure,and symptomatic intracranial hemorrhage within 24 h post-procedure.1∶1 propensity score matchings using the nearest neighbor method was performed based on variables with P＜0.05 in the comparison between the tirofiban and non-tirofiban groups.Differences in primary and safety outcomes between the matched groups were compared.Univariate and multivariate Logistic regression analyses were conducted with favorable outcomes at 90 days as the dependent variable to evaluate the effect of intravenous tirofiban administration after endovascular therapy on 90-day prognosis in patients without successful recanalization.Results A total of 356 patients without successful recanalization after endovascular treatment were included,comprising 195 males and 161 females,with a median age of 70(61,78)years(32-92 years).Among them,76 and 280patients were assigned to the tirofiban and non-tirofiban groups,respectively.At 90 days,114 patients had favorable outcomes,while 242 had unfavorable outcomes.(1)Before the 1∶1 propensity score matching,significant differences were observed between the tirofiban and non-tirofiban groups in terms of admission NIHSS score,ASPECTS,good collateral circulation,intravenous thrombolysis,and mTICI grade(all P＜0.05).After 1∶1 propensity score matching,66 matched pairs(132 patients)were obtained.No significant differences in the baseline and clinical characteristics were found between the two groups after matching(all P＞0.05).(2)After 1∶1 matching,a significant difference was observed in the rate of favorable outcomes at 90 days between the two groups(48.5％[32/66]vs.30.3％[20/66],P=0.033)after propensity score matching,while no significant differences were found in 90-day mortality,intracranial hemorrhage within 24h,or symptomatic intracranial hemorrhage within 24h(all P＞0.05).(3)Univariate analysis after 1∶1 matching indicated that age,atrial fibrillation,smoking history,admission NIHSS score,M2 segment middle cerebral artery occlusion,good collateral circulation,number of passes for thrombus retrieval,and tirofiban treatment were factors influencing favorable outcomes at 90 days.Multivariate Logistic regression analysis showed that younger age(aOR,0.942,95％CI 0.906-0.978,P=0.002),lower admission NIHSS score(aOR,0.855,95％CI 0.777-0.941,P=0.001),good collateral circulation(aOR,5.534,95％CI 2.141-14.301,P＜0.01),tirofiban treatment(aOR,2.774,95％CI 1.092-7.046,P=0.032),and M2 segment MCA occlusion(reference:internal carotid artery occlusion;aOR,4.874,95％CI 1.428-16.632,P=0.011)were independent predictors of favorable outcomes at 90 days.Conclusions Intravenous tirofiban administration after endovascular therapy may improve 90-day neurological outcomes in patients with acute anterior circulation large vessel occlusion stroke who did not achieve successful recanalization without increasing the risk of hemorrhage.Further large-scale randomized controlled trials are warranted to validate these findings.

BACKGROUND:Marine traditional Chinese medicine offers a potentially effective and less adverse treatment for osteoporosis.OBJECTIVE:To explore the pharmacological regulations and procedures of traditional Chinese medicine in treating osteoporosis through data mining and network pharmacology techniques.METHODS:Data mining and network pharmacology methods were used to study the medication pattern and mechanism of marine Chinese medicine patented prescriptions approved by China National Intellectual Property Administration for the treatment of osteoporosis,and special attention was paid to the core Chinese medicine constituents of these prescriptions.The core constituents of the compound drug group composed of oyster-Dipsacus asper-epimedium were comprehensively identified and analyzed by using ultra-high-performance liquid chromatography tandem mass spectrometry.RESULTS AND CONCLUSION:(1)We collected 381 authorized compound patents for the treatment of osteoporosis from the database inception to April 1,2024.Among these,48 patent groups utilized marine traditional Chinese medicine.These prescriptions contained 183 Chinese herbal medicines,of which 13 marine traditional Chinese medicines were used 574 times in total,and the number of flavors used in a single patented formula ranged from 2 to 41.(2)Oyster was the most frequently used marine ingredient,while Dipsacus asper,epimedium,Rehmannia glutinosa,Eucommia ulmoides Oliv.were the most frequent non-marine components.Association rule analysis identified oyster,Dipsacus asper,and epimedium as the core drug group.Network pharmacology analysis revealed that the core targets of this group for the treatment of osteoporosis included ALB,AKT1,TP53,PPARG,and SRC.Sitosterol,liquiritigenin,japonine,luteolin,and kaempferol were identified as the core components within the marine traditional Chinese medicine prescriptions.(3)The GO and KEGFG enrichment analyses suggested a potential association between the mechanism of the core drug group and the rap1/mapk signaling pathway in the treatment of osteoporosis.(4)The molecular docking verified the beneficial interactions between core components and core targets.(5)The ultra-high-performance liquid chromatography tandem mass spectrometry analysis of the compound medicine confirmed the presence of luteolin,sitosterol,kaempferol,and other components,aligning with the drug components identified by network pharmacology.Quantitative analysis indicated that flavonoids,terpenes,and alkaloids constituted a significant proportion of the compound medicine's components.

Objective To observe the clinical efficacy of Xiaoyu Sanjie Prescription,which is derived from classical prescriptions Chaihu Guizhi Ganjiang Tang and Huoluo Xiaoling Dan,in treating middle-risk lung nodules of phlegm blended with blood stasis type.Methods A total of 104 cases of patients with middle-risk lung nodules of phlegm blended with blood stasis type who met the inclusion criteria were randomly divided into the trial group and the control group,with 52 cases in each group.Eventually,a total of 97 cases completed the trial for epidemic outbreak,of which 48 cases were in the trial group and 49 cases were in the control group.Both groups received health training,and then the control group was only given regular follow-up,while the trial group was treated with Xiaoyu Sanjie Prescription orally.The course of treatment covered three months.The changes in traditional Chinese medicine(TCM)syndrome scores and the area of maximum lung nodule of patients in the two groups before and after treatment were observed.After treatment,overall TCM syndrome efficacy and overall western medicine efficacy as well as their efficacies for various nodules types in the two groups were assessed.Results(1)After treatment,the distribution of the grade of TCM syndrome scores in the trial group was improved significantly when compared with that before treatment(P<0.01),while that in the control group showed no significant improvement(P>0.05),and the intergroup comparison after treatment showed that the improvement in the trial group was significantly superior to that in the control group(P<0.01).(2)The total effective rate of overall TCM syndrome efficacy in the trial group was 81.25%(39/48),and that in the control group was 20.41%(10/49);the intergroup comparison(tested by rank sum test)showed that the overall TCM syndrome efficacy in the trial group was significantly superior to that in the control group(P<0.01).In terms of the efficacy for various nodule types,the trial group had stronger TCM syndrome efficacy for multiple nodules,mixed solid nodules,pure ground glass nodules and solid nodules than the control group,in particular the efficacy for multiple nodules and mixed solid nodules,and the differences were all statistically significant(P<0.05 or P<0.01).(3)After treatment,the area of the maximum lung nodule in the trial group was significantly reduced(P<0.01),whereas there was no significant reduction in the control group compared with that before treatment(P>0.05).Statistically significant difference was shown in the post-treatment area between the two groups and in the pre-and post-treatment difference of the area between the two groups(P<0.05 or P<0.01),which suggested that the trial group's effect on the reduction of maximum lung nodule area was significantly superior to that of the control group.(4)With regard to the efficacy of western medicine,on the whole,the total effective rate of overall western medicine efficacy in the trial group was 45.83%(22/48),while that in the control group was 6.12%(3/49),and the intergroup comparison(tested by rank sum test)showed that the overall western medicine efficacy in the trial group was significantly superior to that in the control group(P<0.01).The western medicine efficacy for multiple nodules in the trial group was superior to that in the control group(P<0.01),while no statistically significant difference was presented in western medicine efficacy for mixed solid nodules,solid nodules,and pure ground glass nodules between the two groups(P>0.05).Conclusion Xiaoyu Sanjie Prescription is effective on relieving the clinical symptoms of patients with middle-risk lung nodules of phlegm blended with blood stasis type,and is effective on stabilizing,reducing or even eliminating some of the lung nodules.The compatibility principle of the formula deserves further discussion.

Objective To investigate the therapeutic effects of a newly constructed Aβ25-35-based recombinant gene vaccine for Alzheimer's disease(AD).Methods The pcDNA-Aβ25-35-GRP94 recombinant gene vaccine was con-structed using Aβ25-35 as the epitope and pcDNA3.1 plasmid as the vector.Early APP/PS1 double-transgenic mice were selected as experimental subjects,including the AD control group and the pcDNA-Aβ25-35-GRP94 immunized group for regular immunization.ELISA was performed to detect the titers and isotypes of Aβ-specific antibodies;Morris Water Maze(MWM)Test and Open-Field Test(OFT)were performed to determine the changes in both cognitive ability and mental state of mice;Immunohistochemistry was used to assess the effects of the vac-cine on both Aβ plaques and glial cells in the brains of AD mouse models;ELISA kit was used to evaluate the level of inflammatory factors(TNF-α,IL-1β)in the mouse brain.Results Compared with the AD control group,the pcDNA-Aβ25-35-GRP94 vaccine induced APP/PS1 mice to produce higher levels of Aβ specific antibodies(P<0.05),and mainly induced IgG1 antibodies(P<0.01).The vaccine significantly reduced Aβ plaques in the brain tissue(P<0.05)and effectively alleviated learning memory impairment in APP/PS1 mice(P<0.05)without causing mental behavioral abnormalities.Moreover,the vaccine inhibited the abnormal proliferation of glial cells(P<0.05)and did not cause obvious inflammatory reactions in the brain,suggesting the vaccine was safe and effective.Conclusions Early vaccination with a Aβ25-35-based recombinant gene vaccine can induce the formation of high level of Aβ specific antibodies,effectively alleviate the learning memory impairment of AD and related neu-ro-pathological changes.It may be used to treat AD.

Objective To explore the expression of nuclear transport factor 2(NUTF2)in patients with head and neck squamous cell carcinoma(HNSCC)and analyze its relationship with prognosis.Methods 269 HNSCC patients from Handan Central Hospital between March 2016 and February 2017 were selected.Immunohistochemical staining was used to detect NUTF2 expression levels,comparing tumor tissues with adjacent tissues and NUTF2 expression across different tumor stages.The correlation between NUTF2 expression levels and tumor staging,as well as factors influencing HNSCC patient survival outcomes,were analyzed.Survival situations of HNSCC patients with different NUTF2 expression levels were compared.In vitro experiments were conducted to observe the effects of NUTF2 expression level changes on HNSCC cell proliferation and apoptosis.Results NUTF2 expression levels in HNSCC tumor tissues were higher than in adjacent tissues(P<0.05);NUTF2 expression levels were positively correlated with tumor staging(P<0.05).NUTF2 expression level(HR=3.478,95%CI 1.752～6.906)was a factor influencing HNSCC patient survival outcomes(P<0.05);HNSCC patients with high NUTF2 expression had lower survival rates compared to those with low NUTF2 expression(HR=0.486,95%CI 0.298～0.793,χ2=8.345,P=0.004).Knockdown of NUTF2 expression inhibited HNSCC cell proliferation and promoted cell apoptosis.Conclusion NUTF2 expression levels are abnormally elevated in HNSCC tumor tissues,directly affecting patient survival outcomes,with high NUTF2 expression indicating a poorer prognosis.
