Objective To identify the measurement time,assessment tools,changing trends,factors in longitudinal studies on post stroke fatigue.Methods Web of Science,PubMed,CINAHL,Embase,CNKI,CBM,Wanfang,and VIP database were retrieved from inception until December 15,2024.Results A total of 41 papers were included.The measurement time points used with high frequency were 3,6,and 12 months after stroke.10 assessment tools were retrieved and the fatigue severity scale was most selected.The majority of the studies supported that the incidence of post stroke fatigue showed a decreasing trend within 6 months after stroke,an increasing trend from 6 to 12 months,and a decreasing or steady decreasing trend from 12 months.Post stroke fatigue is influenced by demographic,disease,physiologic,psychological,and coping factors.Conclusion The longitudinal studies on post stroke fatigue focused less than 1 year after stroke,but the recovery period is understudied and specific assessment tools need to be further explored.The trend of post stroke fatigue varies at different stages and exists heterogeneity.Future studies should be optimized to explore influence factors.

Objective To quantitatively evaluate the structure and content of the long-term care insurance(LTCI)policy in China's deeply aging areas.Methods Using the Policy Modeling Consistency(PMC)index model indicator design method,a LTCI policy evalua-tion index system was constructed,consisting of nine primary indicators and 34 secondary indicators.A total of 123 provincial-level LTCI policies issued in deeply aging regions of China between June 1,2014,and October 1,2024 were analyzed.High-frequency word extraction was performed using ROSTCM 6.0,and a social network diagram of LTCI policies was created.The policy structure and content were quantitatively evaluated and ana-lyzed based on the established policy evaluation index system.Results The main content of LTCI policies in deeply aging areas of China covered services,institutions and assessment.The highest policy score was 7.28,and the lowest was 2.20,with an average score of 5.00.There were 25 perfect policies,63 excellent policies,28 good policies and seven qualified policies.In the dimension of policy content,the indexes of five primary indicators of policy evaluation,policy target groups,policy nature,policy perspective and policy tools were 0.60 or more;while the indexes of four primary indicators of policy content,incentives and constraints,policy timeliness,and policy level were 0.50 or less.Conclusion LTCI policies issued in China's deeply aging areas provide comprehensive coverage in aspects such as poli-cy evaluation,policy target groups and policy nature,and need to be improved in policy tool selection and the construction of incentive and constraint mechanisms.

Objective:To explore the risk factors associated with aneurysmal subarachnoid haemorrhage(aSAH)complicated with acute hydrocephalus(aHCP),and to provide the clinical reference for the early identification and intervention of these patients.Methods:The clinical data and laboratory indexes of 175 patients with aSAH were retrospectively analysed,and the patients were divided into aHCP group(n=56)and non-aHCP group(n=119)according to whether they presented with aHCP after the onset of the disease.Univariate analysis and binary logistic regression were applied to identify the risk factors for the aHCP in aSAH patients,and receiver operating characteristic(ROC)curve analysis with area under the curve(AUC)was used to evaluate the predictive value of these factors.Results:A total of 56(32.0%)out of 175 aSAH patients included developed aHCP after the onset of the disease.Compared with non-aHCP group,the levels of neutrophil count,blood glucose,neutrophil-albumin ratio(NAR),platelet-lymphocyte ratio(PLR),neutrophil-lymphocyte ratio(NLR),monocyte-lymphocyte ratio(MLR),systemic immune-inflammatory index(SII),systemic inflammatory response index(SIRI),and systemic inflammation composite index(AISI)of the patients in aHCP group were significantly increased(P<0.05),the level of lymphocyte count was significantly decreased(P<0.05),the Hunt-Hess grade and modified Fisher grade were higher(P<0.05),and the incidence of ventricular haematochezia was more high(P<0.05).The binary Logistic regression analysis results showed that the elevated levels of NAR(OR=2.237,95%CI:1.063-4.708,P=0.034)and NLR(OR=1.210,95%CI:1.095-1.337,P<0.01)were the independent risk factors for the development of aHCP after aSAH.The ROC curve analysis showed that the AUC of NAR was 0.812(95%CI:0.745-0.878,P<0.001),the AUC of NLR was 0.844(95%CI:0.785-0.903,P<0.001),and the combined AUC of NAR and NLR was 0.854(95%CI:0.798-0.910,P<0.001).Conclusion:NAR and NLR are independent risk factors for the development of aHCP in aSAH patients.

Objective To investigate the impact of phase Ⅱ cardiac rehabilitation on the rehabilitation needs and physical activity status of patients after coronary heart disease intervention.Methods A total of 90 patients with coronary heart disease who underwent percutaneous coronary intervention(PCI)in the Coronary Heart Disease Center of the hospital from August 2023 to August 2024 were selected as the research subjects.They were subjected to a 12-week standardized phase Ⅱ cardiac rehabilitation training.General data survey forms,cardiac rehabilitation scales,and the International Physical Activity Questionnaire were used for scale surveys to understand the patients' needs before and after rehabilitation and their weekly physical activity en-ergy expenditure.The cardiopulmonary exercise test gold standard,which reflects exercise capacity through three indicators-maximum oxygen uptake(VO2 max),anaerobic threshold(AT),and metabolic equivalents(MET),were used to compare the physical activity status before and after cardiac rehabilitation.Results Compared with before the implementation,after the implementation of cardiac rehabilitation,the autonomy score in-creased(21.36±1.85 vs.16.73±3.28),the process anxiety(12.60±3.87 vs.14.27±2.12)and outcome anxiety scores(2.31±1.76 vs.4.56±3.56)decreased,the level of low-intensity physical activity decreased[(2 711.62±1 487.09)min/week vs.(3 845.97±2 083.71)min/week],the levels of moderate-intensity[(1 314.67±783.54)min/week vs.(686.22±126.79)min/week],high-intensity[(1 861.33±798.27)min/week vs.(112.00±40.77)min/week],and total physical activity increased[(5 887.62±2 843.54)min/week vs.(4 644.19±2 287.16)min/week].The levels of VO2 max[(28.11±14.28)mL·min-1·kg-1 vs.(23.82±12.34)mL·min-1·kg-1],AT[(16.06±5.41)mL·min-1·kg-1 vs.(13.53±4.56)mL·min-1·kg-1],and MET[(6.89±1.59)mL·min-1·kg-1 vs.(5.78±1.21)mL·min-1·kg-1]all in-creased,with statistically significant differences(P＜0.05).Conclusion Phase Ⅱ rehabilitation after PCI can effectively improve patients' physical activity levels.

OBJECTIVE To evaluate the effect and safety of ciprofol combined with local anesthesia on elderly patients undergoing hemorrhoidectomy.METHODS A total of 108 elderly patients who underwent hemorrhoidectomy at the Department of Proctology,Ruikang Hospital Affiliated to Guangxi University of Chinese Medicine from February 2023 to June 2024,were included.The patients were randomly divided into the etomidate group(54 cases)and the ciprofol group(54 cases)based on a computer-generated random sequence.One patient with intraoperative bleeding and one who refused postoperative examination were excluded,resulting in a final total of 106 patients completing this trial(52 in the etomidate group and 54 in the ciprofol group).The two groups of patients underwent hemorrhoidectomy under local anesthesia with sedative assistance,receiving either etomidate at 0.2 mg/kg or ciprofol at 0.3 mg/kg combined with sufentanil at 0.1 μg/kg.The sedation success rate,induction time,recovery time,operation time and hemodynamic parameters[heart rate(HR),mean arterial pressure(MAP),pulse oxygen saturation(SpO2)and respiratory rate(RR)]were observed at baseline(T0),after successful induction of anesthesia(T1),10 minutes after the start of surgery(T2),and awakening(T3).Additionally,the levels of oxidative stress markers[malondialdehyde(MDA)and superoxide dismutase(SOD)]were measured at T0,T2 and T3.The occurrence of adverse reactions was also recorded.RESULTS The induction time of the ciprofol group was significantly shorter than that of the etomidate group(P＜0.05),while the recovery time was significantly longer in the ciprofol group compared to the etomidate group(P＜0.05).At T1 and T2,HR,MAP and RR of two groups were significantly lower compared to the same group at T0(P＜0.05).However,no significant differences were observed in the hemodynamic parameters at each time point between the two groups(P＞0.05).At T2 and T3,the MDA levels in both groups were significantly higher than at T0,while the SOD levels were significantly lower than the same group at T0;the ciprofol group showed significantly better outcomes than the etomidate group at the same time points(P＜0.05).The proportion of patients with intraoperative somatic movements was significantly lower in the ciprofol group compared to the etomidate group(P＜0.05).CONCLUSIONS When ciprofol is used in elderly patients undergoing hemorrhoidectomy,it demonstrates certain advantages over etomidate in maintaining hemodynamic stability and reducing oxidative stress.Additionally,ciprofol has higher safety.

The geographical origin of forensic evidence provides important information for crime investigation and solving cases,and is one of the key elements of criminal cases.Previous studies have shown significant differences in the distribution of microorganisms in different regions.Detecting environmental DNA samples and inferring the geographical and spatial sources can provide clues and evidence for case handling.However,due to the diversity of criminal environments and the trace amount of frequently encountered exhibits,stable and reliable technical methods for inferring geographical origin from environmental DNA are not yet available.This article summarizes the sample collection and DNA extraction methods for four types of environmental samples:dust,soil,water,and air.It compares the differences between amplicon sequencing and metagenomic sequencing in studying environmental biological populations,outlines the full process of high-throughput sequencing-based data analysis,and focuses on reviewing the research progress in inferring geographical sources of environmental samples based on bacteria,fungi,and other eukaryotes,to provide references for establishing sequencing and analysis methods for environmental DNA in forensic DNA laboratories and exploring environmental DNA information for forensic applications.

Objective To isolate and culture neural crest cells(NCCs)from lung tissue of mice and to identify the characteristics of the cells in order to provide a new cell model for studying lung injury and injure repair.Methods The mT/mG dual-fluorescence reporter mice and Wnt1-Cre transgenic mice were hybridized,and mT/mG;Wnt1-Cre transgenic mice were screened to obtain enhanced green fluorescent protein(EGFP)permanently labeled NCCs.Cell suspension of mouse lung tissue was prepared by enzymolysis.EGFP+cells(namely NCCs)were har-vested by flow cytometry.Primary culture was performed with DMEM/F12 culture medium optimized in the labora-tory,NCCs was characterized by immunofluorescence microscopy.Then NCCs differentiation was directed by mouse bone marrow mesenchymal stem cells osteogenic induction.Results The mT/mG of EGFP permanently labeled NCCs was successfully obtained by hybridization and high-purity NCCs were isolated from Wnt1-Cre transgenic mice lung tissue.They can be cultured in vitro and with spindle morphology which was,similar to fibroblast adherent proliferation.NCCs expressed the neural crest stem cell marker Sox10 and induced to differentiate into osteoblasts.Conclusions NCCs isolated and cultured from lung tissue of mT/mG;Wnt1-Cre transgenic mice show stable prolif-eration and have the characteristics of neural crest stem cells,which may function as a potential cell model for re-search on lung tissue injury and the mechanism of repair.
