Objective To investigate the mechanism of electroacupuncture to improve gastric motility in functional dyspep-sia(FD)model rats by regulating enteric nervous system through PI3K/Akt signaling pathway.Methods SPF grade SD rats were used and randomly divided into blank group,model group,and electroacupuncture group.The multifactorial stress inter-vention method was used in model group and electroacupuncture group to construct the FD rat model,and the modeling period was 14 days.After successful modeling,the electroacupuncture group was treated with electroacupuncture on the ST 36 and LR3 for 10 days.The body weight and food intake of the rats were measured three times at the beginning of the experiment(0 d),at the end of the modeling period(14 d),and at the end of the electroacupuncture intervention(24 d),respectively.At the end of the intervention,the intragastric residual rate,the morphological structure of gastric antrum,and the protein expression levels and locations of PI3K,Akt,and GFAP in the gastric antrum tissue were measured in each group of rats.Results ① Before modeling,the difference between the body weight of rats in each group was not statistically significant(all P＞0.05).After elec-troacupuncture intervention,the body weight ranking of rats in each group was blank group＞electroacupuncture group＞mod-el group,and the differences between groups were all statistically significant(all P＜0.01).② Before modeling,the difference between the body intake of rats in each group was not statistically significant(all P＞0.05).After electroacupuncture interven-tion,the ranking of food intake of rats in each group was blank group＞electroacupuncture group＞model group,and the differ-ences between groups were all statistically significant(all P＜0.01).③ The ranking of intragastric residual rate of rats in each group was blank group＜electroacupuncture group＜model group,and the differences between groups were all statistically sig-nificant(all P＜0.05).④ There was no organic lesions such as hemorrhage,edema,or ulcer in the gastric antrum tissue of rats in each group.⑤The ranking of protein expression levels of PI3K and Akt in gastric antrum tissue of rats in each group was blank group＞the electroacupuncture group＞the model group,and the differences between the groups were all statistically sig-nificant(all P＜0.05).PI3K and Akt proteins were all expressed in the muscular layer of gastric antrum tissue.⑥The ranking of enteric glial cell(EGC)counting in the gastric antrum tissue of rats in each group was blank group＞electroacupuncture group＞model group,and the differences between groups were all statistically significant(all P＜0.05).Conclusion The mech-anism that electroacupuncture can improve gastric motility in FD model rats may be related to activation of PI3K/Akt signaling pathway in the muscle layer of gastric antrum tissue,upregulation of EGC,and improvement of enteric nervous system function.

Objective To explore the influencing factors of early neurological deterioration(END)in patients with acute anterior circulation large-vessel occlusive mild stroke who were treated with medications alone within 72 h after onset.Methods Retrospective consecutive data were collected of patients with acute large-vessel occlusive mild stroke who presented to the Advanced Stroke Center of Linyi People's Hospital within 24 h of onset from January 2021 to December 2022.END was defined as an increase of ≥ 4 points in the National Institutes of Health stroke scale(N1HSS)score within 72 h after onset compared to the admission score.Patients were divided into the neurological deterioration group and the stable condition group(NIHSS score did not increase or increased by 1-3 points within 72 h after onset compared to the admission score).Baseline and clinical data of all patients were collected,including sex,age,cerebrovascular disease risk factors(hypertension,diabetes mellitus,hyperlipidemia,coronary heart disease,atrial fibrillation,smoking,alcohol consumption,stroke history),NIHSS score at admission,time from onset to admission,systolic blood pressure at admission,diastolic blood pressure at admission,laboratory test indicators at admission(blood glucose,glycosylated hemoglobin,homocysteine,total cholesterol,triglyceride,low-density lipoprotein cholesterol,high-density lipoprotein cholesterol,neutrophils,lymphocytes and neutrophil-to-lymphocyte ratio),responsible occlusion artery(internal carotid artery,middle cerebral artery,anterior cerebral artery),affected cerebral hemisphere,collateral circulation score,and medications used within 72 h after admission(intravenous thrombolysis+dual antiplatelet therapy,tirofiban+dual antiplatelet therapy,argatroban+dual antiplatelet therapy,argatroban alone,dual antiplatelet therapy alone).Variables with statistically significant differences in univariate analysis were included in multivariate Logistic regression analysis to explore the independent influencing factors for END in patients with acute anterior circulation large-vessel occlusive mild stroke treated with medications alone.Results A total of 208 patients with acute anterior circulation large-vessel occlusive mild stroke were included,with 143 males and 65 females,aged 38-85 years,with an average age of(64±9)years.Among them,86 patients were in the neurological deterioration group and 122 in the stable condition group.(1)There were statistically significant differences between the neurological deterioration group and the stable condition group in terms of history of diabetes mellitus(39.5％[34/86]vs.17.2％[21/122]),smoking history(43.0％[37/86]vs.29.5％[36/122]),left cerebral hemisphere lesion(57.0％[49/86]vs.41.0％[50/122]),collateral circulation score(4[3,5]vs.5[4,5]),time from onset to admission(7.0[3.0,17.0]hvs.4.3[2.0,11.0]h),blood glucose at admission(7.4[5.8,10.0]mmol/L vs.6.7[5.8,7.7]mmol/L),neutrophil-to-lymphocyte ratio(3.8[2.4,5.1]vs.3.0[2.1,4.3]),dual antiplatelet therapy alone(19.8％[17/86]vs.6.6％[8/122]),and argatroban+dual antiplatelet therapy(8.1％[7/86]vs.29.5％[36/122];all P＜0.05).There were no statistically significant differences in the results of the remaining univariate analyses(all P＞0.05).(2)Multivariate Logistic regression analysis showed that diabetes mellitus(OR,2.674,95％CI 1.121-6.377,P=0.027)and left cerebral hemisphere vessel occlusion(OR,2.030,95％CI I.083-3.806,P=0.027)were independent risk factors for END in acute anterior circulation large-vessel occlusive mild stroke.Argatroban+dual antiplatelet therapy(OR,0.267,95％CI 0.116-0.613,P=0.002)and high collateral circulation score(OR,0.551,95％CI 0.368-0.824,P=0.004)were independent protective factors for END in acute anterior circulation large-vessel occlusive mild stroke.Conclusions Acute anterior circulation large-vessel occlusive mild stroke patients with diabetes mellitus or left cerebral hemisphere lesions are prone to END.The combination of argatroban and dual antiplatelet therapy and good collateral circulation can reduce the risk of END.

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.

FLT3 internal tandem duplication (ITD) mutations are common in acute myeloid leukemia and show an important significance in guiding prognostic stratification and targeted therapy. With the widespread application of high-throughput sequencing technology and the increased ability to analyze mutation sequences, it has been found that more than half of FLT3-ITD mutations are not just tandem duplications but are also accompanied by some complex situations such as the addition of non-template sequences. Recent studies have revealed the sequence characteristics, mutagenesis mechanisms and related clinical prognostic significance of FLT3 length mutations (FLT3-LM). FLT3-LM with added non-template sequences is formed by abnormally activated terminal deoxynucleotidyl transferase. These patients show different treatment responses and prognosis when treated with chemotherapy, targeted therapy, and allogeneic hematopoietic stem cell transplantation, which provides a new perspective to understand FLT3-LM mutations more accurately and provides proposals for FLT3-LM typing based on the mutagenesis mechanism. The new typing rules can better reflect the differences in biological characteristics of the disease and more accurately guide the prognostic stratification and development of individualized treatment for patients with FLT3-LM mutations.

Objective:To investigate the effect of puerarin on myocardial inflammation in rats with heart failure from the Toll-like receptor 4(TLR4)/nuclear transcription factor-κB(NF-κB)inflammatory pathway.Methods:The rat model of heart failure was established by subcutaneous injection of isoproterenol(5 mg/kg for 7 days),and was divided into model group,puerarin group,TLR4 activator group(RS09,25 μg/kg),TLR4 inhibitor group(TAK-242,0.5 mg/kg),puerarin+TLR4 activator group,with 20 rats in each group.Another 20 rats were selected as normal control group.Echocardiography was used to detect heart function;HE staining was used to observe pathological damage of myocardial tissue;TUNEL method was used to detect apoptosis of myocardial tissue cells;ELISA method was used to detect the levels of inflammatory factors IL-6,IL-1β and tumor necrosis factor-α(TNF-α)in myocardial tissue;immunohistochemical method was used to detect the expression of TLR4 and macrophage activation marker-F4/80;Western blot was used to detect the protein expressions of TLR4/NF-κB pathway,MyD88,IL-1 receptor-associated kinase(IRAK)and Galec-tin-3.Results:Compared with the normal control group,the necrosis,inflammatory infiltration and apoptosis of rat myocardial cells were severe in the model group,the heart function was decreased,the inflammatory factor release,macrophage activation,and TLR4/NF-κB pathway protein expression were increased(P<0.05).Puerarin and TLR4 inhibitors could improve the pathological damage of heart failure rats such as myocardial cell necrosis,inflammatory infiltration and apoptosis to the same extent,improve heart function,reduce inflammatory response,inhibit macrophage activation and reduce TLR4/NF-κB pathway activation(P<0.05).TLR4 activator could promote the activation of TLR4/NF-κB pathway,aggravate myocardial cell damage,apoptosis and cardiac function damage in rats with heart failure,and weaken the above-mentioned effects of puerarin(P<0.05).Conclusion:Puerarin may inhibit the activation of TLR4/NF-κB pathway,reduce myocardial inflammation,and play an anti-heart failure effect.
