OBJECTIVE: The investigation of the correlation between ecological factors and the genetic characteristics or metabolites of plants offers valuable insights into the regional causes of genetic and metabolic diversity. Here, Gastrodia elata, a medicinal plant, is employed as a model to explore the environmental factors that influence its genetic characteristics and metabolic accumulations. METHODS: A total of 23 G. elata populations from six cultispecies and 11 cultivated regions were selected based on the predictions of the global geographic information system. The genetic characteristics of these populations were evaluated using highly polymorphic simple sequence repeat markers. Additionally, the metabolic accumulations and antioxidant capacity of mature tubers were measured employing colorimetry and high performance liquid chromatography (HPLC). Ecological data of each region were obtained from the WorldClim-global climate database and harmonized world soil database. To assess the influence of ecological factors on the genetic characteristics and metabolic profiles of G. elata, Pearson's correlation analysis was conducted. RESULTS: Genetic variation among G. elata populations exceeded that within populations. Genetic diverisity, distance and structure manifested regional and species-specific patterns. Metabolic profiling and antioxidant capacity exhibited regional variations. Notably, the Lueyang region demonstrated that a content range of total polysaccharide, total protein, and phenolic glycosides was 9.34%-189.67% higher than the average. Similarly, in the Hubei region, total phenolic content, p-hydroxybenzyl alcohol content, and antioxidant indicators were observed to be higher than the average levels, by 106.57%, 136.47% and 12.50%-91.14%, respectively. Furthermore, ecological factors had a significant comprehensive impact on G. elata genetic characteristics (r > 0.256 and P < 0.05). Multivariate metabolite accumulations in G. elata were influenced by dominant ecological factors. Temperature notably impacted the accumulation of total protein (|r| > 0.528 and P < 0.05). Moisture, encompassing precipitation and soil content, significantly affected the production of phenolic glycosides (|r| > 0.503 and P < 0.05). CONCLUSION The genetic characteristics of G. elata manifested regional and species-specific patterns, with the metabolic accumulations and antioxidant capacity of mature tubers exhibited regional variations. Specifically, multivariate ecological factors comprehensively influenced genetic characteristics. Temperature and moisture played pivotal roles in regulating the accumulations of proteins and phenolic glycosides, respectively. These findings underscore the significant impact of ecological factors on the shaping of G. elata, highlighting their crucial role in enhancing the quality of Chinese medicinal materials.

Recent studies have shown that the physiological homeostasis of oral mucosal cells is regulated by the circadian clock.Dis-ruption or dysfunction of the circadian clock is closely associated with the development of oral squamous cell carcinoma(OSCC).Research based on the circadian clock offers a novel perspective on the pathogenesis and therapeutic strategies for OSCC.However,there is current-ly limited research on this topic,and people generally have insufficient understanding and recognition of the circadian clock.Given the complexity and challenges of circadian clock which is the fourth dimension of medical research,we organize relevant experts based on summarizing the current research results of circadian clock in the pathogenesis and precision diagnosis and treatment of OSCC,combining the scientific principles of the circadian clock's role and their long-term research experience,then summarizes and recommends the con-sensus opinions for the research of circadian clock in the pathogenesis mechanism and precision diagnosis and treatment of human OSCC,with the hope of providing guidance for the basic research and clinical application of circadian clock or circadian rhythm in the pathogene-sis mechanism and precision diagnosis and treatment of oral and maxillofacial squamous cell carcinoma.

Objective To compare the clinical efficacy of typeⅡhybrid surgery versus Sun’s surgery in treating acute Stanford A aortic dissection. Methods A retrospective analysis was conducted on the clinical data of patients with acute Stanford A aortic dissection who were treated at the Central Hospital of Wuhan affiliated to Tongji Medical College, Huazhong University of Science and Technology from 2016 to 2022. According to the surgical method, patients were divided into a typeⅡhybrid group and a Sun’s surgery group, and the clinical efficacy of the two groups was compared. Results A total of 52 patients were included, with 22 in the typeⅡhybrid surgery group and 30 in the Sun’s surgery group. The typeⅡhybrid group consisted of 18 males and 4 females, with an average age of (58.18±6.00) years, while the Sun’s surgery group consisted of 22 males and 8 females, with an average age of (53.03±11.89) years. All surgeries were successfully completed. There were 4 (13.3%) perioperative deaths in the Sun’s surgery group, including 2 patients of multiple organ failure, 1 patient of paraplegia, and 1 patient of uncontrollable postoperative bleeding. There was 1 (4.5%) perioperative death in the typeⅡhybrid surgery group, who was suspected of acute coronary syndrome and took a loading dose of dual antiplatelet drugs preoperatively. The patient underwent secondary thoracotomy for hemostasis, was re-cannulated during the operation, and finally died of circulatory failure after implantation of intra-aortic balloon pumping. There was no statistical difference in perioperative mortality between the two groups (P=0.381). Compared with the Sun’s surgery group, the typeⅡhybrid surgery group had shorter cardiopulmonary bypass time [153.00 (135.00, 185.25) min vs. 182.50 (166.50, 196.75) min, P=0.013], aortic cross-clamping time [77.00 (70.50, 92.00) min vs. 102.50 (93.50, 109.75) min, P<0.001], postoperative ICU stay [4.00 (2.83, 6.00) days vs. 8.00 (6.38, 11.78) days, P<0.001], postoperative ventilator support time [72.00 (29.50, 93.25) h vs. 87.65 (39.13, 139.13) h, P=0.138], less intraoperative blood loss [(1586.82±209.41) mL vs. (1 806.00±292.62) mL, P=0.004], postoperative 24 h drainage volume [612.50 (507.50, 762.50) mL vs. 687.50 (518.75, 993.75) mL, P=0.409], and shorter postoperative hospital stay [18.00 (13.00, 20.25) days vs. 22.00 (17.00, 29.25) days, P=0.013]. There was no statistically significant difference in the incidence of other early postoperative complications such as secondary thoracotomy for hemostasis, tracheotomy, renal dysfunction requiring dialysis, stroke, and paraplegia between the two groups (P>0.05). Conclusion For patients with acute Stanford A aortic dissection, typeⅡhybrid surgery is safe and effective; compared with traditional Sun’s surgery, typeⅡhybrid surgery has relatively less trauma, lower incidence of complications, satisfactory short-term results, and further research is needed on long-term prognosis.

Traditional Chinese Medicine (TCM), as a treasure of the Chinese nation, plays a significant role in maintaining public health. In 2019, the Central Committee of the Communist Party of China and the State Council proposed for the first time the establishment of a TCM registration and evaluation evidence system that integrates TCM theory, "personal experience" and clinical trials (referred to as the "Three-in-One" System) to promote the inheritance and innovation of TCM. Subsequently, the National Medical Products Administration issued several guiding principles to advance the improvement and implementation of this system. Owing to the complexity of its implementation, there are still differing understandings within the TCM industry regarding the positioning of the "Three-in-One" Registration and Evaluation Evidence System, as well as the connotation and value orientation of the "personal experience." To address this, Academician WANG Qi, President of the TCM Association, China International Exchange and Promotion Association for Medical and Healthcare and TCM master, led a group of academicians, TCM masters, TCM pharmacology experts and clinical TCM experts to convene a "Seminar on Promoting the Implementation of the ′Three-in-One′ Registration and Evaluation Evidence System for Chinese Medicinals." Through extensive discussions, an expert consensus was formed, clarifying the different roles of the TCM theory, "personal experience" and clinical trials within the system. It was further emphasized that the "personal experience" is the core of this system, and its data should be derived from clinical practice scenarios. In the future, the improvement of this system will require collaborative efforts across multiple fields to promote the high-quality development of the Chinese medicinal industry.

Objective:To compare the efficacies of endovascular therapy (EVT) and standard medical therapy in acute ischemic stroke (AIS) patients aged ≥85 years, and analyze the independent influencing factors for poor prognosis of AIS patients after EVT.Methods:Sixty-nine AIS patients aged ≥85 years admitted to Department of Neurology, Xi'an Third Hospital from January 2018 to April 2024, including 40 accepted EVT and 28 accepted standard medicinal therapy, were enrolled. Modified Rankin scale (mRS) was used to evaluate the prognosis of the patients 90 days after onset. General data, prognosis and complications between the EVT group and standard medical therapy group were compared. General data, treatment processes and complications between patients with good prognosis and poor prognosis in the EVT group were compared. Multivariate Logistic regression was used to analyze the independent influencing factors for poor prognosis in AIS patients after EVT.Results:Compared with the standard medical therapy, the EVT group had significantly lower NIHSS score at discharge, greater improvement in NIHSS score (NIHSS score at admission-NIHSS score at discharge), lower mRS score 90 days after onset, higher good prognosis rate, lower mortality rate within 90 days of onset, and longer hospital stay ( P<0.05). In the EVT group, 11 patients (27.5%) had good prognosis and 29 patients (72.5%) had poor prognosis 90 days after onset. Compared with the good prognosis group, the poor prognosis group had significantly higher blood glucose level and lower Alberta Stroke Program Early CT Score (ASPECT) on admission ( P<0.05). Multivariate Logistic regression analysis showed that blood glucose on admission ( OR=2.363, 95% CI: 1.134-4.928, P=0.022) and ASPECT score on admission ( OR=0.273, 95% CI: 0.088-0.854, P=0.026) were independent influencing factors for poor prognosis in AIS patients after EVT. Conclusion:AIS patients aged ≥85 years received EVT have better prognosis compared with those accepted standard medical therapy; these patients with high glucose level and low ASPECT score on admission have poor prognosis.

Objective To investigate the correlation between postoperative dry eye syndrome and micro RNA(miR)-223 and miR-143-3p factors in tears of elderly cataract patients.Methods From May 2022 to February 2023,92 elderly cataract patients who underwent cataract surgery in Department of Ophthalmology,Guigang Donghui Hospital were regarded as the study subjects.These subjects were separated into a dry eye group(n=42)and a non dry eye group(n=50)based on the occurrence of dry eyes within 7 days after surgery.Meanwhile,92 healthy individuals who underwent physical examination were collected as the healthy control group.Pearson method was applied to analyze the correlation between the expression levels of miR-223 and miR-143-3p in tears and dry eye diagnostic indicators such as tear film break-up time(BUT),comeal fluorescein staining(FL)score,and tear schirmer's test(SIt).Multivariate logistic regression was applied to analyze the relevant factors affecting the occurrence of dry eye after cataract surgery.Receiver operating characteristic(ROC)curve was applied to analyze the predictive value of tear miR-223 and miR-143-3p for the occurrence of dry eye after cataract surgery.Results The BUT(12.27±1.69s)and SIt(9.17±1.66mm)in the non dry eye group were higher than those in the dry eye group(8.95±1.02s,4.36±0.97mm),while FL(0.74±0.11 score)was lower than that in the dry eye group(2.52±0.37score).and the differences were statistically significant(t=1.136,16.546,32.386,all P＜0.05).The expression level of miR-223(0.87±0.08)in tears of patients in the dry eye group was lower than that of the healthy control group(1.02±0.03)and the non dry eye group(0.92±0.13),while the expression level of miR-143-3p(1.37±0.32)in tears was opposite(1.01±0.02,1.15±0.26),and the differences were statistically significant(t=15.772,2.170;10.793,3.638,all P＜0.05).The expression level of miR-223 in tears was positively correlated with BUT and SIt(r=0.587,0.503,all P＜0.001),and was negatively correlated with FL(r=-0.442,P＜0.001).The expression level of miR-143-3p in tears negatively correlated with BUT and SIt(r=-0.714,-0.549,all P＜0.001),and was positively correlated with FL(r=0.667,P＜0.001).The proportions of patients with a history of angular conjunctival disease and a surgical incision length of ≥ 3mm in the dry eye group were higher than that in the non dry eye group(x2=12.583,6.505,all P＜0.05).The expression level of miR-223 in tears of patients in the dry eye group was lower than that of the non dry eye group,while the expression level of miR-143-3p was higher than that of the non dry eye group(t=2.170,3.638,all P＜0.05).A history of conjunctival disease(OR=1.982),surgical incision length(OR=2.036),and miR-143-3p(OR=1.653)were risk factors for postoperative dry eye in cataract patients,while miR-223(OR=0.574)was a protective factor(P＜0.05).The areas under the curve(AUC)of tear miR-223 and miR-143-3p detection alone predicted the occurrence of dry eye after cataract surgery were 0.692 and 0.719,respectively,while the AUC of their combined detection was 0.880.The combined detection of the two was superior to miR-223 and miR-143-3p detection alone(Z=3.869,3.810,all P＜0.001).Conclusion The occurrence of dry eye in postoperative elderly cataract patients was related to the expression levels of miR-223 and miR-143-3p in tears.

Objective To explore the expression levels of serum glycerophospholipid metabolites lysophosphatidylcholine(LPC)18∶3 and lysophosphatidylethanolamine(LPE)16∶1 in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)and their correlation with clinical prognosis.Methods A total of 112 AECOPD patients diagnosed and treated in Tangshan People's Hospital from January 2019 to January 2022 were selected as the AECOPD group.According to the 3-month follow-up prognosis of the AECOPD group patients,they were divided into survival group(n=90)and death group(n=22).During the same period,60 stable COPD patients were selected as the stable period group,while 60 healthy individuals in the same period were selected as the control group.High performance liquid chromatography tandem mass spectrometry(HPLC-MS/MS)was used to detect serum LPC18∶3 and LPE16∶1 levels in each group.Pearson method was used to analyze their correlation.Logistic regression analysis was used to analyze factors affecting the prognosis of AECOPD patients.Receiver operating characteristic curve was drawn to evaluate the prognostic value of LPC18∶3 and LPE16∶1 in AECOPD patients.The prognosis of AECOPD patients with different serum LPC18∶3 and LPE16∶1 expression groups was compared by K-M curve.Results Serum LPC18∶3(21.67±4.35 μ mol/L),LPE16∶1(16.20±5.17 μ mol/L),PEF％pred,FEV1％pred,and FEV1/FVC％in AECOPD group were lower than those of stable phase group(43.24±6.17 μ mol/L,32.19±5.98 μmol/L)and the control group(68.14±8.78 μ mol/L,44.82±7.44 μ mol/L),with significant differences(F=461.240～1 102.534,all P＜0.05).The serum LPC18:3 and LPE16:1 levels in the AECOPD group were positively correlated with lung function indicators such as PEF％pred,FEV1％pred,and FEV1/FVC％(r=0.603～0.756,allP＜0.05).The course of COPD and PCT of AECOPD patients in the death group were higher than those in the survival group(t=3.961,2.509),while the PEF％pred,FEV1％pred,FEV1/FVC％,serum LPC18∶3(17.20±4.11μ mol/L),and LPE16∶1(10.15±3.03 μ mol/L)in the death group were lower than those in the survival group(22.76±4.35 μ mol/L,17.68±5.22 μ mol/L),with significant differences(t=4.141～6.490,all P＜0.05).Serum LPC18∶3(OR=0.691,95％CI:0.519～0.920)and LPE16∶1(OR=0.586,95％CI:0.382～0.901)were independent protective factors,while the course of COPD(OR=1.510,95％CI:1.203～1.895)and procalcitonin(OR=1.759,95％CI:1.159～2.671)were risk factors affecting the prognosis of AECOPD patients.The area under the curve(95％CI)of combined serum LPC18∶3 and LPE16∶1 for prognosis evaluation of AECOPD patients was better than that of serum LPC18∶3 and LPE16∶1 predicted separately[0.866(0.822～0.907)vs 0.794(0.748～0.830),0.786(0.739～0.836)](Z=3.957,4.195,P=0.002,＜0.001).The mortality risk of AECOPD patients in the low expression group of LPC18∶3 and LPE16∶1 was higher than that in the high expression group of LPC18∶3 and LPE16∶1(log rankx2=4.475,5.763,P=0.034,0.016).Conclusion The serum levels of glycerophospholipid metabolites LPC18∶3 and LPE16∶1 in AECOPD patients were decreased,which were related to lung function status.The combination of the two may effectively evaluate the prognosis of AECOPD patients.

The biological clock(also known as the circadian rhythm)is the fundamental reliance for all organisms on Earth to adapt and survive in the Earth's rotation environment.Circadian rhythm is the most basic regulatory mechanism of life activities,and plays a key role in maintaining normal physiological and biochemical homeostasis,disease occurrence and treatment.Recent studies have shown that the biologi-cal clock plays an important role in the development of oral tissues and in the occurrence and treatment of oral diseases.Since there is cur-rently no guiding literature on the research methods of biological clock in stomatology,researchers mainly conduct research based on pub-lished references,which has led to controversy about the research methods of biological clock in stomatology,and there are many confusions about how to rationally apply the research methods of circadia rhythms.In view of this,this expert consensus summarizes the characteristics of the biological clock and analyzes the shortcomings of the current biological clock research in stomatology,and organizes relevant experts to summarize and recommend 10 principles as a reference for the rational implementation of the biological clock in stomatology research.
