OBJECTIVE:
To precise classify sacral meningeal cysts, effective guide minimally invasive neurosurgery and postoperative personalized rehabilitation by multiple dimensions radiographic reconstruction MRI.
METHODS:
From March to December 2021, based on the original 3D-fast imaging employing steadystate acquisition (FIESTA) scanning sequence, 92 patients with sacral meningeal cysts were pre-operatively evaluated by multiple dimensional reconstruction MRI. The shape of nerve root and the leakage of cyst were reconstructed according to the direction of nerve root or leakage track showed on original MRI scans. Sacral canal cysts were accurately classified as including nerve root and without nerve root, so as to accurately design the incision of skin and formulate corresponding open range of the posterior wall of the sacral canal. Under the microscope intraoperation, the shape of the nerve roots inside cysts or leakage track of the cysts without nerve roots were verified and explored. After the reinforcement and shaping operation, several reexaminations of multiple dimensional reconstruction MRI were performed to understand the deformation of the nerve root and hydrops in the operation cavity, so as to formulate a persona-lized rehabilitation plan for the patients.
RESULTS:
Among the 92 patients with sacral mengingeal cyst, 58 (63.0%) cysts with nerve root cyst, 29 (31.5%) cysts without nerve root cyst, and 5 (5.4%) cysts with mixed sacral canal cyst. In 58 patients with nerve root cysts, the accuracy of preoperative clinical classification on MRI image reached 96.6% (56/58) through confirmation by operating microscope. Only 2 cases of large single cyst with nerve root on the head of cyst were mistaken for without nerve root type. In 29 patients with sacral cyst without nerve root, the accuracy of preoperative image reached 100% through confirmation by operating microscope. The accuracy of judging the internal nerve root and leakage of 12 cases with recurrent sacral cyst was also 100%. Two cases of delayed postoperative hydrops were found one month after operation. After rehabilitation treatment by moxibustion and bathing, the hydrops disappeared 4-6 months after operation.
CONCLUSION
Multiple dimensional reconstruction MRI can precisely make clinical classification of sacral meningeal cysts before operation, guide minimally invasive neurosurgery effectively, and improve the rehabilitation effect.

Allergen-specific immunotherapy(AIT) remains the only therapeutic approach with the potential to modify the natural course of allergic rhinitis(AR). Nevertheless, considerable inter-individual variability exists in patients'responses to AIT. To facilitate more reliable assessment of treatment efficacy, the China Rhinopathy Research Cooperation Group(CRRCG) convened young and middle-aged nasal experts in China to formulate the present consensus. The recommended subjective outcome measures for AIT comprise symptom scores, medication scores, combined symptom and medication scores, quality-of-life assessments, evaluation of disease control, and assessment of comorbidities. Objective indicators may supplement these measures. Currently available objective approaches include skin prick testing, nasal provocation testing, and allergen exposure chambers. However, these methods remain constrained by practical limitations and are not yet appropriate for routine implementation in clinical efficacy evaluation. In addition, several biomarkers, including sIgE and the sIgE/tIgE ratio, sIgG4, serum IgE-blocking activity, IgA, cytokines and chemokines, as well as immune cell surface molecules and their functional activity, have been shown to have associations with AIT outcomes. While these biomarkers may complement subjective assessments, they are subject to significant limitations. Consequently, large-scale multicenter trials and real-world evidence are required to strengthen the evidence base. The present consensus underscores the necessity of integrating patients'subjective experiences with objective testing throughout the treatment process, thereby providing a more comprehensive and accurate framework for efficacy evaluation. Looking forward, future investigations should prioritize the incorporation of multi-omics data and artificial intelligence methodologies, which hold promise for overcoming current limitations in assessment strategies and for advancing both the standardization and personalization of AIT.

BACKGROUND:The decreased postural control ability due to mild cognitive impairment in elderly people leads to the increased risk of falls.Dual-task is the primary research paradigm for evaluating the relationship between cognition and postural control in the scenes close to real life.The sample entropy of the plantar center of pressure(COP)displacement during standing can represent the complexity of postural control. OBJECTIVE:Based on the COP displacement sample entropy,to analyze the differences in postural stability characteristics and control strategies between older adults with mild cognitive impairment and cognitively normal older adults during the dual-task with postural control and spatial working memory,aiming to explore the impact of cognitive impairment on the postural control ability during standing. METHODS:Sixteen older adults with mild cognitive impairment and 17 cognitively normal older adults were eligible and selected for the study.They completed five test tasks,including spatial working memory,double-feet balance stance,Romberg stance,double-feet balance stance-spatial working memory dual-task,and Romberg stance-spatial working memory dual-task,with three valid completions of each task.The plantar COP data were collected by the Kistler 3D force platform.The indicators included cognitive behavior(cognitive score and reaction time)and kinematic indexes(COP displacement and sample entropy). RESULTS AND CONCLUSION:The older adults with mild cognitive impairment performed the spatial working memory task with the greatest cognitive score and the shortest reaction time,the double-feet balance stance-spatial working memory dual-task with moderate cognitive score and reaction time,and the Romberg stance-spatial working memory dual-task with the smallest cognitive score and the longest reaction time,where the differences were significant among the tasks(P<0.05).In the older adults with mild cognitive impairment,the anterior-posterior and medial-lateral COP displacements were significantly greater,and their sample entropy values were significantly smaller in the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task than in the double-feet balance stance and Romberg stance tasks(P<0.05).In the spatial working memory task,there were no significant differences in cognitive score and reaction time between the both groups(P>0.05);however,in the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task,cognitive scores were significantly smaller and reaction times were longer in the older adults with mild cognitive impairment compared with the cognitively normal older adults(P<0.05).In the double-feet balance stance-spatial working memory dual-task and Romberg stance-spatial working memory dual-task,the older adults with mild cognitive impairment exhibited significantly greater anterior-posterior and medial-lateral COP displacements and significantly smaller sample entropy values compared with the cognitively normal older adults(P<0.05).All findings indicate that compared with cognitively normal older adults,older adults with mild cognitive impairment exhibit smaller complexity,poorer systematic adaption and decreased automatic regulation of the postural control during performing the dual-tasks,who are more susceptible to spatial working memory interference,leading to the increased risk of falls.

Objective:To investigate the value of carotid,radial and podalic artery intima thickness(CIT,RIT,PIT)combined with monocyte to high-density lipoprotein ratio(MHR)in predicting the severity of coronary artery stenosis in patients with premature coronary artery disease(PCAD).Methods:A total of 80 patients with PCAD who received treatment in Henan Provincial People's Hospital from October 2023 to May 2024 were prospectively recruited,and they were divided into high group(≥41 score,40 cases)and low group(<41 score,40 cases)according to the median dichotomy of Gensini score. Thirty-four gender,age and body mass index(BMI)-matched healthy volunteers were selected as the control group. The CIT,RIT,PIT,media and intima media thickness of carotid,radial artery and podalic artery(CMT,RMT,PMT,CIMT,RIMT,PIMT)were measured using 24 MHz ultra-high frequency ultrasound probe,and the ratio of intima to media thickness(CIT/CMT,RIT/RMT,PIT/PMT)was calculated. The differences of general clinical data,laboratory indexes and ultrasonic parameters among the three groups were compared. Risk factors affecting the severity of coronary stenosis in PCAD patients were explored by binary logistic regression. Subject working characteristic curves were plotted,area under the curve(AUC)was calculated,and the values of each ultrasound parameter and MHR in the independent and combined diagnosis of the severity of coronary artery stenosis in PCAD patients were evaluated.Results:①There were no statistically significant differences in age,gender,BMI,total cholesterol,CMT,RMT and PMT among the three groups(all P>0.05). There were no statistically significant differences in the comparison of smoking,hypertension,diabetes mellitus,systolic blood pressure,diastolic blood pressure,low-density lipoprotein cholesterol,total cholesterol,and triglycerides between the two subgroups of the PCAD(all P>0.05). ②CIT,CIMT,CIT/CMT,RIT,RIMT,RIT/RMT,PIT,PIMT,PIT/PMT were thickened in the high group compared with the low group,and MHR was higher than in the low group(all P<0.05),the differences in the above parameters remained statistically significant when comparing the PCAD group with the control group(all P<0.05). ③The AUC values for MHR,CIT,RIT and PIT alone to predict the severity of coronary stenosis in patients with PCAD were 0.781,0.767,0.780 and 0.722,respectively. The combined diagnostic efficiency of the four parameters was better than the independent diagnostic efficiency(AUC = 0.885). Conclusions:CIT,RIT and PIT are thicker in PCAD patients with high Gensini score and the combination of artery intima thickness and MHR has good efficacy in predicting the severity of coronary artery stenosis in PCAD patients.

Objective:To analyze the epidemic trend of influenza-like illness(ILI)cases,etiological detection results,and the evolution of the hemagglutinin(HA)gene of the predominant strains in Hanzhong City,Shaanxi Province during the 2018-2024 influenza seasons.Methods:ILI sentinel surveillance data and network laboratory test results during the 2018-2024 influenza seasons in Hanzhong City,Shaanxi Province were collected for descriptive analysis. The HA gene sequences of 25 predominant strains were obtained through whole-genome deep sequencing method,and then compared with the vaccine strains recommended by the World Health Organization in the same period to analyze the evolution of the virus.Results:A total of 37 770 cases of ILI were reported in Hanzhong City during the 2018-2024 influenza seasons,and the proportion of total ILI cases(ILI%)was 2.87%(37 770/1 316 009). The epidemic trend of ILI showed an obvious epidemic peak in winter and spring(from December of the current year to March of the following year). The specimens with the highest positive rate were of type A(H3N2)(39.12%,365/933),and the predominant epidemic strains in each influenza season alternated among A(H1N1)pdm09(in the 2018-2019 and 2022-2023 influenza seasons),A(H3N2)(in the 2019-2020 and 2023-2024 influenza seasons)and B(Victoria)(in the 2021-2022 influenza season). The phylogenetic relationship gradually became more distant over time across different influenza seasons. Among them,the epidemic strains of A(H1N1)pdm09 belonged to the 6B.1 clade,and the evolution mainly occurred in the Sa and Sb regions of the HA epitope. Meanwhile,the epidemic strains of A(H3N2)belonged to the 3C clade,and the evolution mainly took place in the A,B and C regions of the HA epitope. The strains of the B(Victoria)lineage belonged to the V1a.3a.2 clade,and the evolution mainly occurred in the 120-loop,150-loop,and 190-helix regions of the HA epitope.Conclusions:The influenza epidemic in Hanzhong City has obvious seasonality,and the amino acids of the epidemic strains have shown a certain degree of variation over the years. In future prevention and control work,influenza surveillance should be continuously strengthened,and the change trend of the predominant circulating strains should be closely monitored.

Objective To study the spatial distribution of the incidence of pulmonary tuberculosis in Hubei Province and its influencing factors, so as to improve the theoretical basis for scientific development of tuberculosis prevention and control measures in the future. Methods The data of reported incidence of tuberculosis and related influencing factors in various counties and districts of Hubei Province in 2020 were collected. Global Moran's I index, hotspot analysis and geographically weighted regression (GWR) model analysis were used to calculate the spatial autocorrelation of the incidence of tuberculosis, and to analyze the influencing factors affecting the incidence rate of tuberculosis. Results There were obvious regional differences in the space distribution of the incidence rate of tuberculosis. Hot spot analysis showed positive spatial correlation and obvious clustering. The GWR model (AICc=784.251) in this study had higher AICc value compared to the ordinary least squares regression (OLS) model (AICc=804.2585). The GWR model showed that the increase in the proportion of the population aged 65 and above and the proportion of the ethnic minority population had a significant promoting effect on the increase of the incidence rate of tuberculosis, and there was significant spatial heterogeneity. The effect of PM2.5 concentration on the incidence rate of pulmonary tuberculosis varied in different regions, and the degree of effect was also different. Conclusion The proportion of people aged 65 and above and the proportion of ethnic minorities may significantly influence the incidence of pulmonary tuberculosis. The effect of PM2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Abstract
Ferroptosis is a novel form of cell death characterized by the iron-dependent accumulation of lipid hydroperoxides. Since it was first proposed in 2012,Ferroptosis has gradually attracted attention and developed rapidly. Ferroptosis plays an important role in cardiovascular diseases,malignant tumors and neurological diseases,and has become a research hotspot in the field of life science and medicine. Ferroptosis is closely related to iron overload. Iron overload and the accumulation of lipid peroxidation jointly contributes to the disruption of intervertebral disc homeostasis,leading to intervertebral disc degeneration. However,the specific mechanisms of ferroptosis in regulating intervertebral disc degeneration is not yet clear. This review discusses the relationship between ferroptosis and intervertebral disc degeneration,their molecular regulatory mechanisms,and their potential clinical applications,aiming to provide new therapeutic targets for intervertebral disc degeneration.

Objective"Lie flat"has recently become a buzz word describing a specific psychological state in some individuals.However,its psychological meaning and mechanisms remain unclear.Lack of motivation under certain conditions may be one of the key psychological characteristics of this condition.Methods Sixteen male SD rats were randomly assigned to two food-restriction levels(90%and 80%of baseline weight,respectively),and subjected to a sucrose-pellet self-administration task.The establishment of the model is divided into three stages.The rats were trained to self-administer sucrose pellets in a high-reward learning stage and in a low-reward learning stage.We then assessed"lie flat"behavior in a preference-test stage,in which rats could choose between high-reward-and low-reward-paired nose-pokes in a discrete choice procedure.Results Combining self-feeding training with Western blot,the results showed that:(1)rats showed significantly decreased nose-poke behavior for low-reward,i.e."lie flat"behavior,but not for high-reward,when≥90%of the maximal reward was obtained in the high-reward task and the effort(X)in the low-reward task increased to the breaking point.(2)Dopamine D1R expression in the NAc was significantly higher in the"lie flat"group compared with the"not lie flat"rats,while D2R expression was similar in both groups.Conclusions Rats can show"lie flat"behavior,and up-regulation of D1R expression in the NAc may be a key part of the molecular basis responsible for this motivation deficiency in"lie flat"behavior.These results extend our understanding of"lie flat"behavior,and provide a new paradigm for the study of its mechanism.

Purpose To investigate the correlation between molecular typing of urothelial carcinoma(UC)and its clinicopathologic features and prognosis,in order to explore the prognostic markers and therapeutic targets for UC.Methods 115 patients with UC were retrospectively analyzed.Immunohistochemical markers GATA-3,CK20,CK5/6 and CD44 were used for molecular typing of UC(luminal-like type,basal-like type and null).Correlations between molecular typing and clinicopathological features were analyzed using the Chi-square test and Fisher precise test.Sur-vival analysis was performed using the Kaplan-Meier test and Log-rank test.Results The expression of GATA-3 and CK20 was negatively correlated with the clinical stage of UC,while the expression of CD44 was positively correlated with the clinical stage of UC(both P<0.05).CK20 was a marker of good prognosis(P=0.03).The proportion of clinically advanced UC with basal-like type was significantly higher than that of luminal-like type(78.4%vs 53.4%,P=0.033).Among the histologic variants,UC with neuroendocrine differentiation(100%),sarcomatoid carcinoma(80.0%)and squamous differentiation(77.8%)were basal-like type.All plasmacytoid and lymphoepithelioma-like types,as well as 81.8%of micropapillary UC.Among the null phenotypes,the differential variant predominated(66.7%).Compared with the luminal-like type,although the prognosis of basal-like UC was worse,there was no sta-tistically significant difference(P>0.05).Conclusion Patients with CK20-expressing UC had a significantly better prognosis.The main histologic variants types of basal-like type and coelomofacial type are different.Molecular typing of UC using immunohistochemical markers is suggestive of clinical staging and prognosis of patients.
