The translocator protein (TSPO) positron emission tomography (PET) can noninvasively detect neuroinflammation associated with epileptogenesis and epilepsy. This study explored the role of the TSPO-targeting radioligand [¹⁸F]F-TFQC, an m-trifluoromethyl ER176 analog, in the PET neuroimaging of epileptic rats. Initially, [¹⁸F]F-TFQC was synthesized with a radiochemical yield of 8%-10% (EOS), a radiochemical purity of over 99%, and a specific activity of 38.21 ± 1.73 MBq/nmol (EOS). After determining that [¹⁸F]F-TFQC exhibited good biochemical properties, [¹⁸F]F-TFQC PET neuroimaging was performed in epileptic rats at multiple time points in various stages of disease progression. PET imaging showed specific [¹⁸F]F-TFQC uptake in the right hippocampus (KA-injected site, i.e., epileptogenic zone), which was most pronounced at 1 week (T/NT 1.63 ± 0.21) and 1 month (T/NT 1.66 ± 0.20). The PET results were further validated using autoradiography and pathological analysis. Thus, [¹⁸F]F-TFQC can reflect the TSPO levels and localize the epileptogenic zone, thereby offering the potential for monitoring neuroinflammation and guiding anti-inflammatory treatment in patients with epilepsy.

Schizophrenia (SZ) stands as a severe psychiatric disorder. This study applied diffusion tensor imaging (DTI) data in conjunction with graph neural networks to distinguish SZ patients from normal controls (NCs) and showcases the superior performance of a graph neural network integrating combined fractional anisotropy and fiber number brain network features, achieving an accuracy of 73.79% in distinguishing SZ patients from NCs. Beyond mere discrimination, our study delved deeper into the advantages of utilizing white matter brain network features for identifying SZ patients through interpretable model analysis and gene expression analysis. These analyses uncovered intricate interrelationships between brain imaging markers and genetic biomarkers, providing novel insights into the neuropathological basis of SZ. In summary, our findings underscore the potential of graph neural networks applied to multimodal DTI data for enhancing SZ detection through an integrated analysis of neuroimaging and genetic features.

Objective To investigate the quality of life status in patients with type 2 diabetes mellitus and its influencing factors,understand their demands for continuous nursing services,analyze the correlation,and provide a reference for formulating and implementing continuous nursing plans for diabetes in the later stage.Methods From May to December 2024,a cross-sectional survey was conducted among 294 patients with type 2 diabetes mellitus in this hospital by using the Self-Rating Anxiety Scale(SAS),the Diabetes Pa-tient-Specific Quality of Life Scale(DSQL),and the Questionnaire on the Need for Continuous Care.Results The SAS score of patients with type 2 diabetes was 45.76±7.45,DSQL score was 54.68±10.99,and the score of continuous care needs was 32.98±5.79.The quality of life of patients with type 2 diabetes mellitus is mainly influenced by factors such as age,family type,educational level,average monthly family in-come,duration of diabetes,blood glucose control,dietary compliance,intensity of physical exercise,and diabet-ic complications.The quality of life of patients with type 2 diabetes mellitus was positively correlated with need for continuous care(P<0.05).Conclusion The quality of life of patients with type 2 diabetes mellitus is influenced by multiple factors and is related to the need for continuous care.Professional continuous care plans can be formulated and implemented based on the needs of patients with type 2 diabetes mellitus.

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 PM_2.5 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 PM_2.5 concentration varies in different regions, so targeted measures should be formulated according to the situation in different regions.

Objective To explore the mechanism of electroacupuncture in alleviating hyperlipidemia in a rat model by modulating mammalian target of rapamycin complex 1(mTORC1)-mediated lipophagy in hepatocytes.Methods A total of 30 SD rats were randomly divided into blank(n=6)and modeling groups(n=24)using the random number table method.A hyperlipidemic rat model was established by feeding rats a high-fat diet(feeding for 8 weeks).After successful modeling,the modeling group was randomly divided into the model,electroacupuncture,mTORC1 inhibitor,and electroacupuncture+mTORC1 agonist groups,with six rats in each group.Except for the blank group,all other rats were fed with high fat diet.Rats in the electroacupuncture and electroacupuncture+mTORC1 agonist groups received electroacupuncture intervention at bilateral"Fenglong"(ST40)acupoints(dilatational wave 2 Hz/100 Hz,current intensity 1 mA)for 30 min once daily.Rats in the mTORC1 inhibitor group received intraperitoneal injections of the mTORC1 inhibitor,rapamycin(2 mg/kg),once daily.Rats in the electroacupuncture+mTORC1 agonist group received intraperitoneal injections of the mTORC1 agonist MHY1485(10 mg/kg)once daily.The interventions were administered for five consecutive days per week for 4 weeks.Upon completion of the intervention,the following analyses were performed:serum contents of total cholesterol(TC),triglycerides(TAG),low-density lipoprotein cholesterol(LDL-C),high-density lipoprotein cholesterol(HDL-C),free fatty acids(FFA),alanine aminotransferase(ALT),and aspartate aminotransferase(AST)were measured using a fully automated biochemical analyzer.Hepatic histopathological changes and lipid deposition were observed using hematoxylin-eosin and oil red O staining.The liver condition was observed and the liver index was calculated.Hepatic TC and TAG levels were measured using an enzyme-linked immunosorbent assay.The ultrastructure of the liver tissue was observed using transmission electron microscopy,and the mean fluorescence intensity of perilipin 2(PLIN2)and microtubule-associated protein 1 light chain 3(LC3)-Ⅱ in the liver tissue was detected using immunofluorescence.Protein expression of LC3-Ⅱ/LC3-Ⅰ,phosphorylated mammalian target of rapamycin(p-mTOR)/mTOR,and mTORC1 in liver tissue was detected using Western blotting.Results Compared to the blank group,the model group rats showed increased serum TC,TAG,LDL-C,ALT,AST,and FFA levels,along with decreased HDL-C levels(P<0.05).The liver index and hepatic TC and TAG levels were also elevated(P<0.05).Histological examination of liver tissue revealed substantial lipid accumulation,numerous lipid droplets within hepatocytes,abnormal mitochondrial morphology,and scarce autophagic vacuole.The mean fluorescence intensity of PLIN2 increased,whereas that of LC3-Ⅱ decreased(P<0.05).Additionally,the LC3-Ⅱ/LC3-Ⅰ ratio was reduced,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression were increased(P<0.05).Compared to the model group,rats in the mTORC1 inhibitor and electroacupuncture groups exhibited decreased serum TC,TAG,LDL-C,ALT,AST,and FFA levels(P<0.05),along with a reduced liver index and hepatic TC and TAG levels(P<0.05).Histological examination showed markedly attenuated lipid accumulation and visible autophagic vacuole in the hepatocytes.The mean fluorescence intensity of PLIN2 decreased,whereas that of LC3-Ⅱ increased(P<0.05).Moreover,the LC3-Ⅱ/LC3-Ⅰ ratio increased,whereas the p-mTOR/mTOR ratio and mTORC1 protein expression decreased(P<0.05).In comparison with both the electroacupuncture and mTORC1 inhibitor groups,the electroacupuncture+mTORC1 agonist group demonstrated increased serum TAG,TC,LDL-C,ALT,AST,and FFA levels(P<0.05)as well as elevated liver index and hepatic TC and TAG levels(P<0.05).Liver tissues exhibited aggravated lipid deposition and absence of autophagic vacuole in liver cells.The mean fluorescence intensity of PLIN2 was enhanced,whereas that of LC3-Ⅱ was reduced(P<0.05).Furthermore,the LC3-Ⅱ/LC3-Ⅰ ratio decreased,and the p-mTOR/mTOR ratio and mTORC1 protein expression increased(P<0.05).Conclusion Electroacupuncture at"Fenglong"(ST40)may improve blood lipid levels in hyperlipidemic rats by inhibiting mTORC1 and promoting hepatocyte lipophagy.

Objective:To observe the effect of enhanced external counter pulsation on motor function in patients with isch-emic stroke.Method:Sixty patients with ischemic stroke were selected and divided into experimental group(EECP group)and control group(sham EECP group)with a ratio of 1:1.The experimental group was treated with conven-tional hemiplegia rehabilitation training and enhanced external counterpulsation.The control group was treated with the same conventional hemiplegia rehabilitation training program and sham EECP.The following outcomes were observed before and after treatment in the two groups:simplified Fugl-Meyer assessment(FMA),Berg Balance Scale(BBS),Barthel Index(BI).Motor evoked potential(MEP),central conduction time(CMCT),and integral electromyographic(iEMG)of tibialis anterior muscle during isometric contraction during maximum dorsiflexion of the affected ankle were also examined.Result:After treatment,the FMA difference,MEP latency difference,CMCT difference,unit time iEMG and its difference of lower limb anterior tibial muscle in the treatment group were significantly higher than those in the control group(P<0.05).Conclusion:Enhanced external counter pulsation therapy combined with conventional rehabilitation therapy can significantly improve the motor function of the affected side of the lower limb of patients with ischemic stroke in the recovery period,and there is no obvious adverse reaction.

Epilepsy is often comorbid with other neuropsychiatric conditions,which are known as epilepsy comor-bidities.Among these conditions,the comorbidity of epilepsy and migraine is very common.Although they are two differ-ent diseases,they overlap in terms of pathophysiological features and clinical symptoms,and several anti-seizure medica-tions(ASMs)have been proved to be effective in migraine.However,there are still controversies over the concept of epi-lepsy comorbid with migraine,and there is often a lack of effective treatment for migraine due to missed diagnosis or misdi-agnosis.In order to improve the ability for identification and precise treatment of epilepsy comorbid with migraine among clinicians,this article elaborates on the possible mechanism of epilepsy comorbid with migraine and discusses the con-cept,identification,and diagnosis and treatment regimens for epilepsy comorbid with migraine by considering the tempo-ral association between headache symptoms and epileptic seizures,with reference to the classification of epilepsy comorbid with migraine and related diagnostic criteria in Chinese expert consensus(2019)and the ICHD-3-2018 guidelines issued by the International Headache Society.
