The theory of " Sui Qi Suo De" originates from Zhang Zhongjing's Jin Gui Yao Lue and has been further developed by later generations of practitioners, offering significant guidance for clinical practice. Myelodysplastic syndromes (MDS) are common malignant disorders of the hematopoietic system, characterized by high heterogeneity and progressive mutational changes. In Traditional Chinese Medicine (TCM), MDS falls under the category of "marrow toxin exhaustion". This article applies the theory of " Sui Qi Suo De" in TCM to analyze the pathophysiological changes during different stages of MDS. Specifically, it explores the precursor stage (focusing on health maintenance and prevention before illness, addressing the " Suo De" of "gradual decline of vital qi"), the low-risk stage (strengthening the spleen and kidneys, clearing toxic pathogens, addressing the " Suo De" of "weakened vital qi invaded by pathogens"), and the medium-to-high-risk stage (detoxifying and reinforcing the body, harmonizing physical and mental health, addressing the " Suo De" of "dominant pathogens and declining vital qi"). The goal is to provide new directions and theoretical insights for the TCM treatment of MDS.

ObjectiveTo analyze the adverse reactions associated with the clinical use of Banxia （Rhizoma Pinelliae）- Wutou （Aconitum） in the same formula， with the aim of providing a reference for the safety of their clinical application. MethodsLiterature on the clinical application of antagonistic herbs "Banxia-Wutou" used in the same formula， published from January 1st， 2014， to June 30th， 2023， was retrieved from databases including CNKI， VIP， Wanfang， SinoMed， PubMed， Cochrane Library， and Embase. A database was established， and information related to adverse reactions was extracted， including descriptions， classifications， specific manifestations， management and outcomes， patients' primary diseases （western medicine diseases and traditional Chinese medicine diagnoses and syndromes）， and medication information （dosage， ratio， administration routes， and dosage forms）. ResultsA total of 79 researches simultaneously used antagonistic herbs Banxia-Wutou in the same formula and reported associated advers reactions. Gastrointestinal adverse reactions were the most common， with 8 studies reporting management of adverse reactions and 3 studies reporting improvement with no intervention. Among the 11 researches， the adverse reaction relieved to extant， while other 69 researches didn't report the managment of adverse reaction and its prognosis. For the primary disease in western medicine system， chronic bronchitis and chronic obstructive pulmonary disease （COPD） were most common， while gastric pain was the most common symptom in traditional Chinese medicine with spleen and kidney deficiency and spleen stomach cold deficiency being the most frequent syndromes. The most common Banxia dosage was 10 g， while for the Wutou， Fuzi （Radix Aconiti Lateralis Praeparata） was predominant with the highest dose at 15 g. The most frequent herbal combination was Banxia-fuzi， with a 1∶1 ratio. The main administration route was oral， and the primary dosage form was decoction. ConclusionGastrointestinal adverse reactions are the most common in the clinical use of Banxia-Wutou antagonistic herb combinations. Research on the safety of "Banxia-Wutou" combinations should focus on respiratory system diseases and spleen-stomach related conditions.

Objective To investigate the factors affecting cerebral vasospasm in elderly patients af-ter interventional embolization of intracranial aneurysms,and to develop a nomogram prediction model.Methods A total of 307 elderly patients with intracranial aneurysms who underwent inter-ventional embolization in our hospital from May 2021 to May 2023 were recruited,and according to the occurrence of postoperative cerebral vasospasm or not,they were divided into a cerebral vasospasm group(n=63)and a non-cerebral vasospasm group(n=244).The general clinical data were compared between two groups.Univariate and multivariate logistic regression analyses were used to identify the risk factors for postoperative cerebral vasospasm in elderly patients with in-tracranial aneurysms,and then a nomogram prediction model was constructed.Results There were significant differences between the two groups in terms of age,Hunt-Hess grade,Fisher grade,and time window for surgical treatment(P＜0.01).The cerebral vasospasm group had sig-nificantly higher WBC count and IL-1β and Caspase-3 levels than the non-cerebral vasospasm group(P＜0.01).Univariate logistics regression analysis showed that seven indicators,that is,aged≥65 years,Hunt-Hess grade Ⅲ-Ⅵ,Fisher grade Ⅲ-Ⅵ,later surgical start time and in-creased WBC count and IL-1β and Caspase-3 levels were risk factors for postoperative cerebral vasospasm(P＜0.05).Multivariate logistics regression analysis indicated that above seven indica-tors were still independent risk factors for postoperative cerebral vasospasm(OR=11.372,95％CI:4.032-32.073,P=0.000;OR=12.415,95％CI:4.979-30.959,P=0.000;OR=9.568,95％CI:3.945-23.206,P=0.000;OR=2.898,95％CI:1.217-6.901,P=0.016;OR=1.762,95％CI:1.125-2.761,P=0.013;OR=1.153,95％CI:1.035-1.283,P=0.009).ROC curve analysis re-vealed that the AUC value of the nomogram model in predicting postoperative cerebral vasospasm was 0.934,with a sensitivity of 85.40％and a specificity of 90.50％.Conclusion Aged≥65 years,Hunt-Hess grade Ⅲ-Ⅵ,Fisher grade Ⅲ-Ⅵ,later surgical start time and increased WBC count and IL-1β and Caspase-3 levels have adverse effects on postoperative cerebral vasospasm in in eld-erly patients after interventional embolization of intracranial aneurysms.The nomogram model based on these factors shows certain efficacy in evaluating the occurrence of cerebral vasospasm.

Objective To observe changes of dynamic functional connectivity(dFC)of brain networks in different stages of Parkinson disease(PD).Methods Totally 52 early-stage PD patients(early PD group),36 late-stage PD patients(late PD group)and 38 healthy controls(HC group)were prospectively enrolled,and resting-state functional MRI were performed.The sliding window,independent component analysis and k-means clustering were used to extract dFC intensity and temporal properties,including fractional windows,dwell time and transition frequency.Results Network connectivity patterns within and between visual network(VIS),sensorimotor network(SMN),default mode network(DMN),cerebellar network(CB)and cognitive executive network(CEN)were altered in PD patients.Four dFC states were identified,in which connections between components in states Ⅰ and Ⅱ were compact,while in states Ⅲ and Ⅳ were sparse.The fractional window and dwell time of late PD group,early PD group and HC group successively increased under state Ⅱ,but successively decreased under state Ⅲ(all P＜0.05).Under state Ⅰ and Ⅳ,no significant difference of fractional window nor dwell time was found between early PD group and late PD group(both P＞0.05),and the above indexes under state Ⅰ were both lower than those in HC group(all P＜0.05),the fraction window under state Ⅳ was higher than that in HC group(both P＜0.05).Conclusion The temporal properties of dFC in PD patients were altered,characterized by increased tendency toward segregated states.Furthermore,fractional windows and dwell time were associated with PD disease stages,suggesting that dFC parameters might serve as novel biomarkers for assessing clinical progression of PD.

Objective To investigate the effect of linezolid on platelets in patients with acute myeloid leukemia(AML)and analyze the safety profile of linezolid by comparing the platelet count and bleeding risk of linezolid during bone marrow suppression in patients after chemotherapy for AML.Methods A retrospective study was conducted on patients who underwent chemotherapy for AML in a tertiary hospital from January 2020 to November 2024.The patients treated with linezolid and those not receiving linezolid were matched in a 1∶2 ratio.The safety of linezolid during bone marrow suppression after chemotherapy for AML was analyzed in terms of platelet count＜20×109/L,＜50×109/L,minimum platelet count,total platelet transfusion volume,and clinical bleeding events.Results A total of 126 patients were enrolled,including 42 patients receiving linezolid and 84 patients not receiving linezolid.There was no significant difference between linezolid group and control group in the days for platelet count＜20×109/Land＜50×109/L.No life-threatening severe bleeding events were reported in either group.The time to platelet recovery and time to platelet count increase prolonged significantly in patients who received linezolid treatment for more than 7 days during bone marrow suppression.Albumin＜35 g/L may prolong the time to platelet count increase.Conclusions This study suggests that short-term use of linezolid for not more than 7 days is safe during bone marrow suppression in patients after chemotherapy for AML.When linezolid is used for more than 7 days,the time required for platelet recovery and platelet count increase will be significantly prolonged.In cases of albumin＜35 g/L,the time required for platelet count increase may be prolonged.These findings can inform clinical decision-making and help optimize infection management strategies for AML patients.

Objective This study aimed to apply the integrated Promoting Action on Research Implementation in Health Services(i-PARIHS)framework to translate best evidence into clinical practice,with the goal of reducing unplanned discontinua-tion of continuous renal replacement therapy(CRRT)and providing guidance for clinical staff.Methods A systematic search was conducted for guidelines,systematic reviews,evidence summaries,and expert consensus documents related to unplanned CRRT discontinuation.Retrieved literature underwent quality appraisal,synthesis,and integration.Through evidence-based group discussions,baseline clinical audits,and FAME(Feasibility,Appropriateness,Meaningfulness,Effectiveness)-based evi-dence appraisal,implementation strategies were developed across three i-PARIHS dimensions:context,recipients,and facilita-tion.Outcomes including unplanned CRRT discontinuation rates,average length of hospital stay,mortality,and nurse competen-cy were compared before and after evidence implementation.Results After evidence extraction,synthesis,and contextual adap-tation,a site-specific evidence translation model was established,comprising 16 audit criteria with corresponding review methods.Following implementation,significant reductions were observed in unplanned CRRT discontinuation rates,average length of stay,and mortality(all P＜0.05).Nurses' nursing competency also improved significantly(P＜0.05),indicating a positive impact of the evidence translation initiative.Conclusion The i-PARIHS framework effectively reduces unplanned CRRT discontinuation and is applicable in clinical practice.The results offer evidence for improving nursing quality and offering a reference for future evidence translation initiatives in critical care.

Objective:To explore the predictive value of cervical length(CL)measured at 16-24 weeks of ges-tation for spontaneous preterm birth in twin pregnancies.Methods:A retrospective study was conducted on 1001 twin pregnancy cases,including 569 cases in the spontaneous preterm birth group and 432 cases in the term birth group.Univariate and multivariate Logistic regression analyses were used to identify factors associated with spon-taneous preterm birth.The predictive value of CL for spontaneous preterm birth was analyzed by the receiver op-erating characteristic(ROC)curve.Results:At 16-24 weeks of pregnancy,the CL in the spontaneous preterm birth group(3.460±0.866 cm)was significantly shorter than that in the term birth group(3.711±0.589 cm),and the difference was statistically significant(P=0.005).There were statistically significant differences in the cervical fun-neling and its morphology between the term birth group and the spontaneous preterm birth group(P<0.05).Multivariate Logistic regression analysis showed that monochorionicity(aOR 0.161,95％ CI 0.074-0.351) and CL at 16-24 weeks of pregnancy(aOR 0.655,95％ CI 0.496-0.864) were influencing factors for spontaneous preterm birth(P <0.05).ROC curve analysis indicated that a CL cutoff of 3.045 cm at 16-24 weeks of pregnancy predicted spontaneous preterm birth before 34 weeks,with a sensitivity of 90.2％ ,specificity of 64.9％ ,and an area under the curve of 0.650.Conclusions:Measurement of CL at 16-24 weeks of pregnancy is a potential predictor of spontaneous preterm birth in twin pregnancies.In addition,when establishing a prediction model for spontaneous preterm birth,future research should also consider cervical funnel morphology.
