Objective: To investigate the epidemiological characteristics and spatial-temporal clustering of severe fever with thrombocytopenia syndrome (SFTS) in Huai'an City, Jiangsu Province from 2011 to 2024, so as to provide a basis for optimizing local SFTS prevention and control strategies, and identifying high-risk areas and key populations. Methods: Data on SFTS incidence and deaths in Huai'an City from 2011 to 2024 were collected from the Infectious Disease Reporting Information System of the Chinese Disease Prevention and Control Information System. The reported incidence, mortality, and fatality rates were calculated. Descriptive analysis was performed on temporal, population, and regional distribution. The average annual percent change (AAPC) was used to analyze the trend in the reported incidence of SFTS. Global and local spatial autocorrelation analyses were employed to examine the spatial distribution patterns and spatial association patterns of SFTS incidence while spatio-temporal scanning analyses was used to assess the spatial-temporal clustering of SFTS. Results: A total of 337 SFTS cases were reported in Huai'an City from 2011 to 2024, with the reported incidence rising from 0.17/100 000 to 1.88/100 000. There were 20 deaths, with an average annual mortality of 0.03/100 000, and a fatality rate of 5.93%. The incidence showed obvious seasonality, with a peak in May and June (148 cases, accounting for 43.92%). Spring and summer accounted for 107 cases (31.75%) and 159 cases (47.18%), respectively. The reported SFTS cases were mainly male, farmers, and individuals aged ≥41 years, accounting for 56.38%, 79.23%, and 96.74%, respectively. The population distribution of death cases was basically consistent with that of incident cases. Xuyi County was a high-incidence area, with a total of 332 reported cases, accounting for 98.52%. All death cases were reported in this county. Spatial autocorrelation analyses revealed a positive spatial correlation in SFTS incidence from 2019 to 2024, with Moran's I values ranging from 0.214 to 0.336 (all P<0.05). Heqiao Town, Tianquanhu Town, and Guiwu Town in Xuyi County were identified as high-high clustering areas. Spatio-temporal scanning analyses showed that cluster 1 was consistent with the high-high clustering areas, with an aggregation time from the second quarter of 2019 to the second quarter of 2022. Conclusions From 2011 to 2024, the reported incidence of SFTS in Huai'an City showed an upward trend, with a high incidence in spring and summer. Males, farmers, and the middle-aged and elderly population were the key populations for prevention and control. Xuyi County was the key area for prevention and control.

ObjectiveTo investigate whether Huanglian Jiedutang can inhibit neutrophil infiltration in the brains of middle cerebral artery occlusion （MCAO） mice by regulating the expression of neutrophil-related chemokines in exosomes， thereby achieving therapeutic effects. MethodsA total of 130 male specific pathogen-free （SPF） C57BL/6J mice were randomly divided into four groups： Sham-operated group， MCAO model group， Huanglian Jiedutang group （6 g·kg^-1）， and Ginaton group （21.6 mg·kg^-1）， with 10 mice in the Ginaton group and 40 mice in each of the remaining three groups. Mice in the Huanglian Jiedutang group and the Ginaton group were administered the corresponding drugs by oral gavage once daily at a volume of 0.15 mL·（10 g）^-1 for 7 consecutive days， while the sham-operated and model groups received an equal volume of saline via the same route. After 7 days， MCAO surgery was performed. The distal and proximal ends of the right common carotid artery （CCA） were ligated， a small incision was made between the two ligatures， and a silicone rubber-coated monofilament with a rounded tip was inserted into the lumen to occlude the CCA. The filament was left in place for 1 h to establish a focal cerebral ischemia model. At 24 h after modeling， mice were evaluated. Neurological function was assessed using the Longa score. Cerebral infarct volume was measured by 2，3，5-triphenyltetrazolium chloride （TTC） staining. Cerebral blood flow was observed by laser speckle imaging. Hematoxylin and eosin （HE） staining and Nissl staining were used to observe pathological changes in brain tissues. Exosomes were isolated from mouse plasma and brain tissues by ultracentrifugation and molecular size exclusion and identified by electron microscopy， particle size analysis， and protein blotting. Long-chain RNA libraries of exosomes were constructed and sequenced. Real-time quantitative reverse transcription polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression of inflammatory factors and neutrophil-related chemokines in exosomes from plasma and brain tissues of each group. Enzyme-linked immunosorbent assay （ELISA） was used to detect the protein expression of inflammatory factors and neutrophil-related chemokines in exosomes from brain tissues of each group. Immunohistochemistry was used to detect the expression of the neutrophil-specific protein myeloperoxidase （MPO） in the brains of mice in each group. ResultsCompared with the sham-operated group， the model group showed decreased neurological function scores （P<0.01）， obvious cerebral infarction （P<0.01）， reduced cerebral blood flow （P<0.01）， neuronal necrosis in the brain， and decreased numbers of Nissl bodies （P<0.01）. The mRNA expression levels of IL-1β， MPO， CXCL1， CXCL2， CXCL3， CXCL10， CCL2， and CCL3 in exosomes from plasma and brain tissues were significantly increased （P<0.05， P<0.01）. The protein expression levels of IL-1β， MPO， CXCL2， and CXCL10 in exosomes from brain tissues were increased （P<0.05， P<0.01）， and MPO-positive rates and mean optical density values in brain tissues were elevated （P<0.01）. Compared with the model group， the Huanglian Jiedutang group and the Ginaton group showed increased neurological function scores （P<0.05）， reduced cerebral infarct volume （P<0.01）， restored cerebral blood flow （P<0.01）， reduced necrotic cells in the brain， and increased numbers of Nissl bodies （P<0.01）. In the Huanglian Jiedutang group， the mRNA expression levels of IL-1β， MPO， CXCL1， CXCL2， CXCL3， CXCL10， CCL2， and CCL3 in exosomes from plasma and brain tissues were decreased （P<0.05， P<0.01）. The protein expression levels of IL-1β， MPO， CXCL2， and CXCL10 in exosomes from brain tissues were reduced （P<0.05， P<0.01）， and MPO-positive rates and mean optical density values in brain tissues were decreased （P<0.01）. ConclusionHuanglian Jiedutang can effectively regulate the expression of neutrophil-related chemokines in exosomes from plasma and brain tissues of MCAO mice， thereby reducing neutrophil infiltration in the brain and achieving therapeutic effects.

ObjectiveTo investigate whether Huanglian Jiedutang （HLJD） and its major active constituents （geniposide， baicalin， and berberine） can inhibit the inflammatory response of BV2 cells under lipopolysaccharide （LPS） stimulation via the high-mobility group protein B1 （HMGB1）/Toll-like receptor 4 （TLR4）/nuclear factor-κB （NF-κB） signaling pathway， and to explore differences in therapeutic efficacy among the three monomers， their combined formula， and HLJD under equal content ratios. MethodsBV2 microglial cells were used as the primary experimental model. Cell viability was assessed using the cell counting kit-8 （CCK-8） method to examine the effects of different concentrations of dimethyl sulfoxide （DMSO， 0.8%， 0.4%， 0.2%， 0.1%， and 0.05%） on cell viability. IncuCyte was employed to monitor the growth of cells under different concentrations of HLJD （200， 100， 50， 25， 12.5， 6.25 mg·L^-1）. Nitric oxide （NO） assay was used to screen the optimal HLJD concentration. High-performance liquid chromatography （HPLC） determined the content of geniposide， baicalin， and berberine in HLJD， and experimental groups were subsequently established according to the relative proportions of these constituents. CCK-8 assay evaluated cell viability under different treatments. Enzyme-linked immunosorbent assay （ELISA） measured levels of inflammatory factors （TNF-α， IL-1β， IL-6， IL-10） in the supernatant. Flow cytometry assessed the effects of treatments on M1-type polarization of BV2 cells. Western blot determined the expression levels of HMGB1， TLR4， and NF-κB-related proteins. ResultsCompared with the blank group， DMSO at concentrations ≤0.2% did not affect cell viability within 48 h. BV2 cell growth plateaued at 24 h after treatment with 200 mg·L^-1 HLJD. Under stimulation with 2 mg·L^-1 LPS， this concentration of HLJD effectively reduced NO release， and 6 h pre-treatment had a stronger inhibitory effect on NO than direct administration. HPLC results showed that 1 mg of HLJD freeze-dried powder contained approximately 24 μg of geniposide， 15 μg of baicalin， and 30 μg of berberine. Based on these ratios， experimental groups were blank， LPS （2 mg·L^-1）， HLJD （200 mg·L^-1）， monomer combination， geniposide （4.8 mg·L^-1）， baicalin （3 mg·L^-1）， and berberine （6 mg·L^-1）. The monomer combination group consisted of all three active constituents dissolved together. LPS and HLJD or its active constituents did not affect cell viability compared with the blank group. LPS significantly increased TNF-α， IL-1β， IL-6， and IL-10 in the supernatant （P<0.01）. HLJD and its active constituents significantly reduced pro-inflammatory factors TNF-α， IL-1β， and IL-6 （P<0.05， P<0.01） while upregulating anti-inflammatory IL-10 （P<0.01）， with the monomer combination showing the strongest effect （P<0.05， P<0.01）. Compared with the blank group， LPS significantly increased the proportion of CD80⁺CD86⁺ （M1-type） BV2 cells （P<0.01）. HLJD and its constituents partially inhibited M1 polarization （P<0.05， P<0.01）， with the monomer combination exhibiting the most pronounced effect （P<0.05， P<0.01）. Compared with the blank group， LPS upregulated HMGB1， TLR4， and NF-κB-related proteins （P<0.01）， whereas HLJD and its active constituents significantly reduced their expression （P<0.05， P<0.01）， with the monomer combination having the strongest regulatory effect （P<0.05， P<0.01）. ConclusionHLJD and its major active constituents （geniposide， baicalin， berberine） can inhibit LPS-induced inflammatory responses in BV2 cells. The combination of the three active constituents demonstrates the most potent anti-inflammatory effect， significantly attenuating M1-type polarization of BV2 cells via the HMGB1/TLR4/NF-κB signaling pathway.

AIM: To investigate the abnormal conditions and change patterns of accommodative facility in patients with different refractive states before and after small incision lenticule extraction(SMILE)surgery.METHODS:A prospective clinical cohort study was conducted. A total of 59 patients(118 eyes)who underwent SMILE surgery and had visual function files established in our hospital from June to December 2023 were randomly selected, including 37 males and 22 females, aged 18-35 years(with an average age of 25.19±5.65 years). According to the preoperative spherical equivalent(SE), they were divided into two groups: the low-to-moderate myopia group(SE≥-6.00 DS)with 40 patients(80 eyes), and the high myopia group(SE<-6.00 DS)with 19 patients(38 eyes). The monocular and binocular accommodative facility before surgery and at 1 wk and 1 mo after surgery were compared, and the changes in accommodative facility before and after SMILE surgery in the two groups of patients were analyzed.RESULTS:All surgeries were completed successfully. In the low-to-moderate myopia group, 33 cases(66 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 17.5%(7/40). In the high myopia group, 15 patients(30 eyes)completed the 1-month follow-up after surgery, with a loss to follow-up rate of 21.1%(4/19). After SMILE surgery, the uncorrected visual acuity and SE of both low-to-moderate myopia and high myopia were significantly improved(all P<0.05). The accommodative facility of the right eyes in all the patients at 1 mo after surgery was better than that before surgery and at 1 wk after surgery(P=0.002, 0.006), the accommodative facility of the left eyes was significantly increased at 1 mo after surgery than that at 1 wk after surgery(P=0.005), and the binocular accommodative facility at 1 mo after surgery was significantly increased compared with that before surgery(P<0.017). Furthermore, there were statistical significance in accommodative facility of the right eyes in the low-to-moderate group at 1 mo compared with that before surgery and at 1 wk after surgery(P=0.011, 0.004); it was significantly increased in the left eyes at 1 mo after surgery compared with that at 1 wk after surgery(P=0.001), and binocular accommodative facility at 1 mo after surgery was significantly better than that before surgery(P<0.001). Furthermore, there was no statistical significance in the right, left and binocular accommodative facility of patients in the high myopia group(all P>0.017).CONCLUSION: After SMILE surgery, the monocular accommodative facility shows a transient decrease and then exceeds the preoperative level at 1 mo after surgery, and the binocular accommodative facility gradually improves after surgery. SMILE surgery has a positive impact on the monocular and binocular accommodative facility in patients with low-to-moderate myopia, but has no significant impact on the accommodative facility in patients with high myopia. It is of clinical significance to strengthen the detection of monocular and binocular accommodative facility before and after SMILE surgery.

Internal carotid artery(ICA)occlusion is one of the main causes of ischemic stroke.Endovascular treatment is one of the main surgical methods for symptomatic non-acute ICA occlusion.However,how to optimize the surgical strategy to improve the success rate of recanalization of occluded vessels require further exploration.The authors reported a case of subacute ICA occlusion treated with endovascular treatment.During the operation,intravascular ultrasound(IVUS)was used for high-resolution and precise assessment of the lumen morphology,plaque characteristics and vessel wall structure in the occluded segment.The surgical strategy was individualized,ultimately achieving successful recanalization of the occluded vessel.Combined with literature review of the clinical characteristics of subacute ICA occlusion and the application of IVUS in this type of lesion,in order to provide reference and inspiration for further optimization of interventional surgical strategies.

Objective This study analyzes the optical coherence tomography(OCT)characteristics of patients with symptomatic carotid artery stenosis(CAS)prior to carotid stenting and the influencing factors associated with symptomatic CAS.Methods This study retrospectively included consecutive CAS patients who underwent carotid OCT examination prior to carotid stenting at Department of Nerolgical Intervention and Nerological Intensive Care,Central Hospital of Dalian University of Technology(Dalian Municipal Central Hospital)from November 2022 to November 2024.Patients were categorized into symptomatic and asymptomatic CAS groups.General clinical data and laboratory test results were collected and compared between the two groups,including age,sex,body mass index,systolic and diastolic blood pressure(measured on the morning of procedure without antihypertensive medication intervention with patient at resting state for over 30 minutes),medical history(including hypertension,diabetes,atrial fibrillation,coronary heart disease,stroke,and transient ischemic attack),smoking history,alcohol consumption history,and fasting laboratory results obtained on the morning before procedure laboratory results(including,white blood cell count,red blood cell count,monocyte percentage,neutrophil percentage,lymphocyte percentage,platelet count,blood creatinine,blood glucose,international normalized ratio,D-dimer,total cholesterol,triglycerides,homocysteine,low-density lipoprotein cholesterol,and high-density lipoprotein cholesterol).Additionally,OCT image parameters were collected and compared between the two groups,including the minimum lumen diameter and minimum lumen area of the target lesion segment,the distal lumen diameter and area of the reference vessel(internal carotid artery),the percentage of lumen area stenosis([reference vessel lumen cross-sectional area-minimum lumen cross-sectional area]/reference vessel lumen cross-sectional area×100%),the lesion length,fibrous cap thickness,lipid arc,and the presence of fibrous plaques,calcified plaques,lipid plaques,white thrombus,cholesterol crystals,macrophage infiltration,microchannels,and plaque rupture.Variables with P＜0.05 from univariate analysis were included in the multivariate Logistic regression analysis to assess the influencing factors of symptomatic CAS.Results A total of 68 patients with CAS were enrolled,comprising 57males and 11females,aged 53 to 84 years with a mean age of(68±7)years.Among them,32 patients were categorized into the symptomatic CAS group and 36 into the asymptomatic CAS group.(1)Compared to the asymptomatic CAS group,patients in the symptomatic CAS group exhibited higher systolic blood pressure([150±23]mmHg vs.[138±21])mmHg,P=0.025).There were no statistically significant differences in general,clinical data,and laboratory test results between the two groups(all P＞0.05).The preoperative OCT imaging parameters comparison between the two groups of CAS patients revealed that the reference vessel distal lumen area was significantly smaller in the symptomatic CAS group([18.67±5.44]mm2 vs.[21.95±5.57]mm2,P=0.017),and the proportion of patients with white thrombus(40.62%[13/32]vs.13.89%[5/36],P=0.013)and microchannels(21.88%[7/32]vs.2.78%[1/36],P=0.014)were higher.(2)A multivariate Logistic regression analysis was conducted using systolic blood pressure,white thrombus,microchannels,and the reference vessel(internal carotid artery)distal lumen area as independent variables.The results indicated that high systolic blood pressure(OR,1.030,95%CI 1.002-1.060,P=0.038),and the presence of white thrombus(OR,3.956,95%CI 1.072-14.600,P=0.039)and microchannels(OR,13.850,95%CI 1.277-150.203,P=0.031)were independent risk factors for symptomatic CAS.Conclusions Compared to patients with asymptomatic CAS,those with symptomatic CAS exhibited higher preoperative(pre-carotid stenting)systolic blood pressure and a smaller distal lumen area of the reference vessel(internal carotid artery),as observed through OCT.Furthermore,a higher proportion of symptomatic CAS patients presented with white thrombus and microchannels.Preoperative systolic blood pressure,along with the presence of white thrombus and microchannels on OCT,are identified as independent risk factors for symptomatic CAS.The conclusions drawn from this study necessitate further validation through large-scale,multicenter,prospective research.

Objective To investigate the relationship between plasma homocysteine(Hcy)levels and cognitive impairment(CI).Methods From November 2018 to January 2019,baseline data and cognitive function were collected from the participants aged≥40 years who lived in two villages in Huyi District,Xi'an,China.Their global cognitive function was assessed by Mini-Mental State Examination(MMSE)and the diagnosis of cognitive impairment was based on international guidelines.Fasting blood was collected in the morning,and plasma Hcy level was measured by the chemiluminometric assay.Multivariate Logistic regression analysis,subgroup analysis,and interaction analysis were performed to investigate the relationship between plasma Hcy and CI.Results A total of 1 805 subjects were included in the analysis.There were 1 056 females(58.5％),age ranged from 40 to 88 years[mean(58.99±9.52)years],and 145 participants(8.0％)were diagnosed as CI.The median plasma Hcy level in the overall population was 14.1(11.6,17.8)μmol/L.There were 729(40.4％)subjects in the HHcy group(＞15.0 μmol/L)and 1 076(59.6％)in the normal group(≤15.0 μmol/L).Univariate analysis showed that the prevalence of CI was higher in the HHcy group than in the normal Hcy group(11.4％vs.5.8％,P＜0.001).In multivariable Logistic regression fully adjusted for potential confounders,each 1 μmol/L increase in plasma Hcy level was associated with a 3.0％increased risk of CI(OR=1.030,95％CI:1.012-1.048,P=0.001).Interaction analysis indicated that sex,age,BMI,systolic blood pressure,history of stroke,and diabetes did not significantly modify this association.Conclusion Elevated plasma Hcy levels are associated with an increased risk of CI in people aged≥40 years.This indicates that HHcy may be a risk factor for CI.

Objective:To investigate the distribution of CGG repeat numbers in the FMR1 gene among reproductive-age women in China, providing data reference for carrier screening and genetic counseling of Fragile X syndrome. Methods:This cross-sectional study recruited 16 610 reproductive-age women from 12 medical institutions between July 2022 and October 2023. Peripheral venous blood samples (3 mL) were collected, and genomic DNA was extracted. The number of CGG repeats in the FMR1 gene was determined using the triplet-primed polymerase chain reaction (TP-PCR) combined with capillary electrophoresis technology. Statistical analyses were performed to assess the prevalence and distribution of CGG repeat expansions. Results:Among 16 610 women of childbearing age, 5 684 (34.220%) women had the same number of CGG repeats in the two alleles of FMR1 gene, and 10 926 (65.780%) women had different numbers of repeats in the two alleles. Among the 33 220 FMR1 alleles in 16 610 women of reproductive age, the most common CGG repeat numbers were 29 [48.645% (16 160/33 220)] and 30 [26.276% (8 729/33 220)], while the most frequent CGG genotype was CGG 29/29 [24.726% (4 107/16 610)]. The CGG repeat numbers of FMR1 gene were normal in 16 498 women (99.326%). Among the 112 women (0.674%) with CGG repeat abnormities, 96 (0.578%) women were classified as intermediate carriers, 15 (0.090%) as premutation carriers, and 1 (0.006%) as a full mutation carrier, whose CGG genotype was (36, >200). Conclusion:In the general reproductive-age female population in China, the normal CGG repeat numbers of the FMR1 gene account for 99.326%, while the intermediate carrier rate is 0.578%, and the combined carrier rate of the premutation and full mutation types is 0.096%.

Objective:To investigate the computed tomography (CT) imaging features of patients with chronic hydrocephalus after intracerebral hemorrhage surgery and the difference between endoscopic third ventriculostomy (ETV) and ventricular peritoneal shunt (VPS).Methods:A total of 158 patients with intracerebral hemorrhage who received surgical treatment in the Department of Neurosurgery of the People′s Hospital of Jinan from January 2021 to June 2023 were retrospectively selected as the study objects, including 78 patients with chronic hydrocephalus after surgery as the hydrocephalus group, and 80 patients with no hydrocephalus after surgery as the non-hydrocephalus group, and the CT imaging data of the patients were statistically analyzed. Hydrocephalus group was divided into ETV group (42 cases) and VPS group (36 cases) according to different treatment methods. The efficacy and quality of life of the two groups were compared, and the incidence of complications in the two groups were counted.Results:There was no significant difference between hydrocephalus group and non-hydrocephalus group in the site of cerebral hemorrhage, hematoma morphology and the proportion of patients with mixed signs, lobular signs and black hole signs (all P>0.05). The proportion of patients with ventricular dilation and hematoma enlargement in hydrocephalus group was significantly higher than that in non-hydrocephalus group (all P<0.05). The National Institute of Health Stroke Scale (NIHSS) scores of hydrocephalus patients in the two groups were measured continuously at different time points, and there was no significant difference in NIHSS scores between the ETV group and the VPS group before treatment, at 2 weeks and 4 weeks of treatment (all P>0.05). There was no significant difference between the ETV group and the VPS group ( P>0.05). The recurrence rate of the ETV group was lower than that of the VPS group ( P<0.05). The quality of life scores of patients in ETV group were higher than those in the VPS group at 3 months and 6 months after surgery ( P<0.05). Conclusions:CT examination of patients with chronic hydrocephalus after intracerebral hemorrhage will show obvious characteristics of hematoma enlargement and ventricle enlargement. The efficacy of ETV and VPS in the treatment of chronic hydrocephalus after intracerebral hemorrhage surgery is similar, but the former has a lower recurrence rate and a higher postoperative quality of life.
