ObjectiveTo investigate the present situation of input, output, outcome and impact of all registered community-based rehabilitation stations in Inner Mongolia in China, and analyze how the input predict the output, outcome and impact. MethodsFrom March 1st to April 30th, 2025, a questionnaire survey was conducted on all registered community-based rehabilitation stations in Inner Mongolia, covering four dimensions: input, output, outcome and impact. A total of 1 365 questionnaires were distributed. The input included four items: laws and policies, human resources, equipment and facilities, and rehabilitation information management. The output included two items: technical paths and benefits/effectiveness. The outcome included three items: coverage rates, rehabilitation interventions and functional results. The impact included two items: health and sustainability. Each item contained several questions, all of which were described in a positive way. Each question was scored from one to five. A lower score indicated that the situation of the community-based rehabilitation station was more in line with the content described in the question. Regression analysis was performed using the total score of each item of input dimension as independent variables, and the total scores of the output, outcome and impact dimensions as dependent variables. ResultsA total of 1 262 valid questionnaires were collected. The mean values of input, output, outcome and impact of community-based rehabilitation stations were 1.827 to 1.904, with coefficient of variation of 45.892% to 49.239%. The regression analysis showed that, rehabilitation information management, human resources, and laws and policies significantly predicted the output dimension (R² = 0.910, P < 0.001). Meanwhile, all four items in the input dimension predicted both the outcome (R² = 0.850, P < 0.001) and impact dimensions (R² = 0.833, P < 0.001). ConclusionInput, output, outcome and impact of the community-based rehabilitation stations in Inner Mongolia were generally in line with the content of the questions, although some imbalances were observed. Additionally, the input of community-based rehabilitation stations could significantly predict their output, outcome and impact.

Objective:To explore the impact of body constitutional metabolic phenotype on the outcomes of hypertensive intracerebral hemorrhage (HICH) patients one year after onset.Methods:This study retrospectively studied the clinical data of 467 HICH patients admitted to the First People's Hospital of Lianyungang City from May 2021 to May 2023. Based on telephone follow-up after one year, the patients were categorized into two groups: a good outcome group (287 cases) and a poor outcome group (180 cases). According to the patients' body mass index (BMI) and metabolic status, the population was divided into six phenotypes: metabolically healthy with normal weight (MH-NW), metabolically healthy with overweight (MH-OW), metabolically healthy obesity (MHO), metabolically unhealthy normal weight (MU-NW), metabolically unhealthy with overweight (MU-OW), and metabolically unhealthy with obesity (MUO). The baseline data of the two groups were compared between two groups. The influencing factors of adverse outcomes in patients with HICH one year after onset were analyzed. Quantitative data that conforms to normal distribution were represented by xˉ±s, and independent sample t-test was used for comparison between two groups; The measurement data of skewed distribution was represented by M ( Q1, Q3), and Mann Whitney U test was used for comparison between the two groups; Count data was presented as an example (%), and comparison between groups was conducted using the χ2 test. Multivariate logistic regression analysis was used to analyze the influencing factors of poor prognosis in HICH patients one year after onset. Results:BMI, high density lipoprotein cholesterol(HDL-C) levels and baseline Glasgow coma score(GCS) score in the poor outcome group were lower than those in the good outcome group [23.8 (22.4, 26.1) kg/m 2 vs. 25.0 (22.5, 27.4) kg/m 2, Z=-2.31, P=0.021; 1.1 (1.0,1.4) mmol/L vs. 1.3 (1.0,1.6) mmol/L, Z=-4.18, P<0.001; 14 (13,15) score vs. 10 (7,13) score, Z=-10.20, P<0.001]. The incidence of hemorrhage into the ventricle, cerebral hernia, pulmonary infection and hydrocephalus [43.3%(78/180) vs. 23.7% (68/287). 5.6%(10/180) vs. 0.7% (2/287), 48.9%(88/180) vs. 6.6% (19/287), 5.0%(9/180) vs. 1.4% (4/287), χ2=19.86, P<0.001, χ2=10.43, P<0.001, χ2=111.90, P<0.001, χ2=5.32, P=0.021], proportion of surgical removal of hematoma [41.1%(74/180) vs. 19.5% (56/287), χ2=25.69, P<0.001], systolic blood pressure [158 (141,173) mmHg vs. 152 (138,169) mmHg, Z=-2.18, P=0.029] and fasting blood glucose [6.9 (5.7,8.2) mmol/L vs. 6.3 (5.4,7.8) mmol/L, Z=-2.08, P=0.038] were higher than those in good outcome group. The metabolic phenotypes in the poor conversion group were as follows: 41 cases (22.8%) of MH-NW, 23 cases (12.8%) of MH-OW, 9 cases (5.0%) of MHO, 54 cases (30.0%) of MU-NW, 33 cases (18.3%) of MU-OW, and 20 cases (11.1%) of MUO. Conversely, the metabolic phenotypes in the good conversion group were as follows: 67 cases (23.3%) of MH-NW, 77 cases (26.8%) of MH-OW, 31 cases (10.8%) of MHO, 40 cases (13.9%) of MU-NW, 46 cases (16.0%) of MU-OW, and 26 cases (9.1%) of MUO. Regarding metabolic types, the poor conversion group comprised 73 healthy cases (40.6%) and 107 unhealthy cases (59.4%), whereas the good conversion group had 177 healthy cases (61.7%) and 110 unhealthy cases (38.3%). In terms of body mass, the poor conversion group included 94 cases (52.2%) of normal weight, 57 cases (31.7%) of overweight, and 29 cases (16.1%) of obesity. Conversely, the good conversion group had 108 cases (37.6%) of normal weight, 122 cases (42.5%) of overweight, and 57 cases (19.9%) of obesity.There were statistically significant differences in the composition ratios of physical metabolic phenotype, metabolic type, and xBMI type between the two groups of patients ( χ2=29.56, P<0.001, χ2=19.83, P<0.001, χ2=9.68, P=0.008). Multivariate Logistic regression analysis showed that after adjusting for other risk factors related to the prognosis of HICH, HDL-C ( OR=0.30, 95% CI: 0.12-0.75, P=0.010), admission GCS score ( OR=0.71, 95% CI:0.64-0.79, P<0.001), MH-OW ( OR=0.38, 95% CI: 0.17-0.82, P=0.013) and MHO ( OR=0.30, 95% CI:0.09-0.99, P=0.048) were all protective factors for adverse outcomes in patients with HICH 1 year after the onset of the disease, and hemorrhage into the ventricle ( OR=2.46, 95% CI:1.41-4.32, P=0.002) and pulmonary infection ( OR=9.13, 95% CI: 4.78- 17.44, P<0.001) were risk factors for adverse outcomes. Conclusions:MH-OW and MHO are beneficial to the prognosis of HICH patients 1 year after the onset of HICH. The secondary prevention of HICH patients should pay attention to the BMI level and comprehensive metabolic status of the patients.

Objective:To investigate the age-specific distribution characteristics of plantar pressure parameters in healthy children aged 3-12 years.Methods:This cross-sectional study retrieved data from the hospital information system in January 2025 for 272 children aged 3-12 years who underwent physical examinations and voluntarily completed plantar pressure analysis at Beijing Children′s Hospital, Capital Medical University, from July 2022 to December 2024. Demographic and clinical data, including anthropometric measurements (height and weight), flatfoot diagnosis and plantar pressure parameters (maximum pressure, time to maximum force, and contact time percentage in bilateral forefoot, midfoot, and hindfoot) were recorded. Participants were categorized into 3 age groups (3-6 years, 7-9 years, and 10-12 years) and were grouped by gender as well. Intergroup comparisons used one-way ANOVA or least-significant difference test or χ2 tests. Spearman′s rank correlation assessed the relationship between flatfoot prevalence and age. Results:Among 272 children (143 boys, 129 girls), age groups comprised 3-6 years (118 children, 64 boys and 54 girls), 7-9 years (96 children, 49 boys and 47 girls), and 10-12 years (58 children, 30 boys and 28 girls). Flatfoot prevalence was higher in boys than in that of girls (41.3% (59/143) vs. 28.7% (37/129), χ2=4.70, P=0.030), and negatively correlated with age ( r=-0.21, P<0.001). There all had statistically differences in the maximum pressure values of the bilateral forefoot and hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). The maximum pressure values of bilateral midfoot in the group of aged 10-12 years were all higher than those of the other two groups (all P<0.001). There had no statistically differences in the time maximum force value of the bilateral forefoot among the 3 age groups (all P>0.05). The time maximum force values of bilateral midfoot in the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). There all had statistically differences in the time maximum force value of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There all had statistically differences in the contact time percentage values of the bilateral forefoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all the lowest, and those of the group of aged 10-12 years were all the highest (all P<0.05). There had no statistically differences in the contact time percentage values of the bilateral midfoot among the 3 age groups (all P>0.05). There all had statistically differences in the contact time percentage values of the bilateral hindfoot among the 3 age groups (all P<0.001), and after pairwise comparison, those of the group of aged 3-6 years were all lower than those of the other two groups (all P<0.05). Conclusion:Plantar pressure parameters exhibit distinct age-related patterns, reflecting the development of gait patterns and foot arch formation, which will be useful for monitoring physical growth and sports rehabilitation.

Objective:To explore the relief effect and mechanism of electroacupuncture in rats with knee osteoarthritis (KOA) based on the NF-κB/NLRP3 signaling pathway.Methods:SD rats were divided into a blank control group, a model group, an electroacupuncture group, and an electroacupuncture+PMA group using a random number table method, with 10 rats in each group. Except for the blank control group, all other groups were used to prepare KOA models. After successful modeling, rats in the electroacupuncture group and electroacupuncture+PMA group were subjected to electroacupuncture stimulation on both sides of the "Yanglingquan"(GB34), "Neixiyan"(EX LE4), and "Waixiyan"(EX-LE5); the electroacupuncture+PMA group received intraperitoneal injection of 5 mg/kg PMA once a day for 11 consecutive days of intervention; the blank control group and model group did not receive any intervention. Thermal foot contraction latency (TWL) and mechanical foot contraction threshold (MWT) were detected. HE staining was used to observe the inflammation and damage of synovial tissue and knee articular cartilage tissue. ELISA was used to detect the levels of calcitonin gene-related peptide (CGRP), pain mediator substance P (SP) and IL-6 in serum. The expressions of CGRP, iNOS proteins in dorsal root ganglion were detected by immunofluorescence assay. The expressions of CGRP, iNOS, p-p65/p65, NLRP3, Caspase-1, ASC proteins in dorsal root ganglia were detected by Western blot.Results:Compared with the model group, the TWL and MWT of the rats in the electroacupuncture group (3, 6, 9 and 11 days) significantly increased ( P<0.05), the pathological damage of synovial tissue and knee articular cartilage tissue were reduced, serum CGRP, SP, IL-6 levels significantly decreased ( P<0.05), and the expressions of CGRP, iNOS, p-p65/p65, NLRP3, Caspase-1, ASC proteins in dorsal root ganglion significantly decreased ( P<0.05); PMA significantly inhibited the effect of electrolysis on KOA rats ( P<0.05). Conclusion:Electroacupuncture can alleviate pain symptoms in KOA rats, and the mechanism may be related to the inhibition of the activation of NF-κB/NLRP3 signaling pathway.

Objective To evaluate the efficacy and safety of DSA-guided continuous radiofrequency ablation(CRF)and high-voltage,long-duration pulsed radiofrequency(HL-PRF)of ganglia impar in treating perineal pain in patients with rectal cancer.Methods This study is a single-center,randomized,active-controlled,double-blind trial that included 57 rectal cancer patients with perineal pain.At a 1∶1 ratio,the patients were randomly divided into CRF group(n=28)and HL-PRF group(n=29).The primary outcome indicators were the pain numerical rating scale(NRS)scores determined at the preoperative(T0),postoperative 24 h(T1),one week(T2),one month(T3),3 months(T4)and 6 months(T5)time-points.The secondary outcome indicators included the sitting time at T0,T1,T2,T3,T4 and T5 time-points,the 9-item patient health questionnaire(PHQ-9)score,the pittsburgh sleep quality index(PSQI)score,the postoperative oral morphine dosage,and the incidence of perineal numbness.Results Compared with the value at T0 time-point,in both groups the NRS score,PHQ-9 score and PSQI score at T1-T5 time-points were significantly decreased,while the sitting time become remarkably increased(all P＜0.05).No statistically significant differences in postoperative oral morphine dosage and incidence of perineal numbness existed between the two groups(both P＞0.05).There were no statistically significant differences in NRS score,PHQ-9 score and PSQI score,sitting time and oral morphine dosage at T1,T2,T3 time-points between CRF group and HL-PRF group(all P＞0.05),while at T4 and T5 time-points the NRS score,PHQ-9 score and PSQI score in HL-PRF group were significantly higher than those in CRF group(all P＜0.05),and the sitting time in HL-PRF group was strikingly lower than that in CRF group(P＜0.05).Conclusion Both CRF and HL-PRF of ganglion impar can alleviate perineal pain in patients with advanced rectal cancer and improve the quality of life of patients.CRF is superior to HL-PRF in the long-term efficacy.

Background:To compare the efficacy and safety of monthly administrations of gonadotropin releasing hormone (GnRH) agonists LY01005 and Zoladex ? in Chinese patients with premenopausal breast cancer. Methods:From October 2020 to November 2021, 188 premenopausal breast cancer patients were enrolled in 34 hospitals and randomized 1:1 to receive either LY01005 or Zoladex ? every 28 days for a total of three injections. All patients concomitantly received oral tamoxifen (TAM). The primary efficacy endpoint was cumulative probability of maintaining menopausal level [oestradiol (E2) ≤30 pg/ml] from day 29 to day 85. The second efficacy endpoint included changes in E2, luteinizing hormone (LH), and follicle-stimulating hormone (FSH) compared with the baseline. Pharmacokinetics (PK), pharmacodynamics (PD), and safety were analyzed. The study also evaluated the pharmacokinetic and pharmacodynamic characteristics of LY01005. Results:A total of 188 patients were randomised and 187 patients received either LY01005 or Zoladex ?. Cumulative probabilities of maintaining menopausal level (E2≤30 pg/ml) from day 29 to day 85 were 93.1% for LY01005 and 86.3% for Zoladex ?. The between-group difference was 6.8% (95% CI: -2.3%, 15.9%) and primary efficacy in the LY01005 group was not inferior to that in the Zoladex ? group. Changes in E2, LH, and FSH levels compared with the baseline were equivalent between the two groups (E2: 89.34% to 90.23% vs. 82.11% to 85.02%; LH: 88.89% to 95.52% vs. 89.70% to 97.02%; FSH: 75.36% to 80.85% vs.73.07% to 80.24%, respectively). After three consecutive doses of LY01005, the LH and FSH levels of the subjects showed a transient increase after the first dose, reached a peak on the second day and then started to decrease. The LH and FSH reached a lower level and remained at or below that level until the 85th day. Both treatments were well-tolerated. Conclusion:LY01005 is as effective as Zoladex ? in suppressing E2 to menopausal levels in Chinese patients with premenopausal breast cancer, with a similar safety profile.

Objective:To investigate the role of hypoxia-induced angiopoietin-like protein 4 (ANGPTL4) expression in experimental choroidal neovascularization (CNV).Methods:Twenty-seven SPF male C57BL/6J mice aged 6-8 weeks were selected.Eighteen of the mice were used to establish a laser-induced CNV model.On the 7th day after laser photocoagulation, success of the modeling was verified using optical coherence tomography angiography (OCTA) and fundus fluorescein angiography (FFA). The retinal pigment epithelium (RPE)-choroid-sclera complex was extracted for protein analysis before modeling and on the 3rd and 7th days after modeling.The relative expression levels of ANGPTL4 and vascular endothelial growth factor (VEGF) at different time points were detected by Western blot.Additionally, frozen sections of mouse eyeballs on day 7 after modeling were prepared and the expression and cellular localization of ANGPTL4 were observed by immunofluorescence.RF/6A cells, derived from monkey choroidal retinal endothelial cells, were treated with 200 μmol/L cobalt chloride (CoCl 2) in the culture medium for 0, 3, 6, and 12 hours.RF/6A cells were also divided into a normal control group, a hypoxia group, and a hypoxia+ si-ANGPTL4 group, and cells were transfected with a plasmid containing si-ANGPTL4 sequence.The relative expression levels of ANGPTL4 and VEGF proteins in each group were detected by Western blot, and the differences in tube formation among the groups were observed by tube formation assay.A total of 27 male C57BL/6J mice were randomly divided into CNV group, CNV+ si-NC group, and CNV+ si-ANGPTL4 group, with 9 mice in each group.In the CNV+ si-NC and CNV+ si-ANGPTL4 groups, si-NC and si-ANGPTL4 were respectively injected into the vitreous cavity after the CNV model was established.Fluorescence leakage in mice was observed by FFA, and the length, thickness and area of CNV was observed using OCTA and immunofluorescence staining of choroidal flat mounts.The relative expression levels of ANGPTL4 and VEGF proteins in each group were detected by Western blot.All animal experiments were conducted in accordance with ARVO Statement on the Use of Animals in Ophthalmic and Vision Research.The experimental protocol was approved by the Affiliated Hospital of Nantong University (No.S20220822-902). Results:Before modeling and on the 3rd and 7th days after modeling, the relative expression levels of ANGPTL4 protein were 1.00±0.00, 1.58±0.05, and 1.90±0.04, respectively, and the relative expression levels of VEGF protein were 1.00±0.00, 1.31±0.05, and 1.84±0.04, respectively, with statistically significant overall differences ( F=528.934, 390.424, both P<0.05). Among them, on the 3rd and 7th days after modeling, the relative expression levels of ANGPTL4 and VEGF proteins were significantly higher in CNV group than in the control group (all P<0.05). The tissues of each layer of the retina were clear in the control group, while neovascularization could be seen growing under the retinal neuroepithelial layer in the CNV group.Compared with the control group, ANGPTL4 expression was significantly increased and colocalized with vascular endothelial cells in the CNV group.After CoCl 2 treatment of RF/6A cells for 3, 6, and 12 hours, the relative expression levels of ANGPTL4 and VEGF proteins were higher than at 0 hour, with statistically significant differences (all P<0.05). Compared with the control group, the relative ANGPTL4 protein expression was increased in the hypoxia group and significantly decreased in the hypoxia+ si-ANGPTL4 group, showing statistically significant differences (both P<0.05). The number of tube formations in the control group, hypoxia group, and hypoxia+ si-ANGPTL4 group were 12.67±1.53, 19.64±1.56, and 17.01±1.04, respectively, with a statistically significant overall difference ( F=33.091, P<0.01). The number of tube formations increased in the hypoxia group and hypoxia+ si-ANGPTL4 group compared with the control group, and the number of tube formations decreased in the hypoxia+ si-ANGPTL4 group compared with the hypoxia group, with statistically significant differences (all P<0.05). Relative expression levels of ANGPTL4 and VEGF proteins were significantly lower in the CNV+ si-ANGPTL4 group than those in the CNV group (both P<0.05). The CNV area was significantly lower in the CNV+ si-ANGPTL4 group than in the CNV group and CNV+ si-NC group (both P<0.05). Conclusions:Hypoxia-induced ANGPTL4 promotes experimental CNV formation in vivo and in vitro.Inhibiting ANGPTL4 can reduce CNV formation and leakage.

Objective To understand the changing composition and antibiotic resistance of bacterial species in the clinical isolates from outpatient and emergency department(hereinafter referred to as outpatients)and inpatient children over time in various hospitals,and to provide laboratory evidence for rational antibiotic use.Methods The data on clinically isolated pathogenic bacteria and antimicrobial susceptibility of isolates from outpatients and inpatient children in the CHINET program from 2015 to 2021 were collected and analyzed.Results A total of 278 471 isolates were isolated from pediatric patients in the CHINET program from 2015 to 2021.About 17.1％of the strains were isolated from outpatients,primarily group A β-hemolytic Streptococcus,Escherichia coli,and Staphylococcus aureus.Most of the strains(82.9％)were isolated from inpatients,mainly SS.aureus,E.coli,and H.influenzae.The prevalence of methicillin-resistant S.aureus(MRSA)in outpatients(24.5％)was lower than that in inpatient children(31.5％).The MRSA isolates from outpatients showed lower resistance rates to the antibiotics tested than the strains isolated from inpatient children.The prevalence of vancomycin-resistant Enterococcus faecalis or E.faecium and penicillin-resistant S.pneumoniae was low in either outpatients or inpatient children.S.pneumoniae,β-hemolytic Streptococcus and S.viridans showed high resistance rates to erythromycin.The prevalence of erythromycin-resistant group A β-hemolytic Streptococcus was higher in outpatients than that in inpatient children.The prevalence of β-lactamase-producing H.influenzae showed an overall upward trend in children,but lower in outpatients(45.1％)than in inpatient children(59.4％).The prevalence of carbapenem-resistant Klebsiella pneumoniae(CRKpn),carbapenem-resistant Pseudomonas aeruginosa(CRPae)and carbapenem-resistant Acinetobacter baumannii(CRAba)was 14％,11.7％,47.8％in outpatients,but 24.2％,20.6％,and 52.8％in inpatient children,respectively.The prevalence of multidrug-resistant E.coli,K.pneumoniae,Proteus mirabilis,P.aeruginosa and A.baumannii strains was lower in outpatients than in inpatient children.The prevalence of fluoroquinolone-resistant E.coli,ESBLs-producing K.pneumoniae,ESBLs-producing P.mirabilis,carbapenem-resistant E.coli(CREco),CRKpn,and CRPae was lower in children in outpatients than in inpatient children,but the prevalence of CRAba in 2021 was higher than in inpatient children.Conclusions The distribution of clinical isolates from children is different between outpatients and inpatients.The prevalence of MRSA,ESBL,and CRO was higher in inpatient children than in outpatients.Antibiotics should be used rationally in clinical practice based on etiological diagnosis and antimicrobial susceptibility test results.Ongoing antimicrobial resistance surveillance and prevention and control of hospital infections are crucial to curbing bacterial resistance.

Objective To investigate the changing antibiotic resistance profiles of E.coli isolated from patients in the 52 hospitals participating in the CHINET program from 2015 to 2021.Methods Antimicrobial susceptibility was tested for clinical isolates of E.coli according to the unified protocol of CHINET program.WHONET 5.6 and SPSS 20.0 software were used for data analysis.Results Atotal of 289 760 nonduplicate clinical strains ofE.coli were isolated from 2015 to 2021,mainly from urine samples(44.7±3.2)％.The proportion of E.coli strains isolated from urine samples was higher in females than in males(59.0％vs 29.5％).The proportion of E.coli strains isolated from respiratory tract and cerebrospinal fluid samples was significantly higher in children than in adults(16.7％vs 7.8％,0.8％vs 0.1％,both P＜0.05).The isolates from internal medicine department accounted for the largest proportion(28.9±2.8)％with an increasing trend over years.Overall,the prevalence of ESBLs-producing E.coli and carbapenem resistant E.coli(CREco)was 55.9％and 1.8％,respectively during the 7-year period.The prevalence of ESBLs-producing E.coli was the highest in tertiary hospitals each year from 2015 to 2021 compared to secondary hospitals.The prevalence of CREco was higher in children's hospitals compared to secondary and tertiary hospitals each year from 2015 to 2021.The prevalence of ESBLs-producing E.coli in tertiary hospitals and children's hospitals and the prevalence of CREco in children's hospitals showed a decreasing trend over the 7-year period.The prevalence of CREco in secondary and tertiary hospitals increased slowly.Antibiotic resistance rates changed slowly from 2015 to 2021.Carbapenem drugs(imipenem,meropenem)were the most active drugs amongβ-lactams against E.coli(resistance rate≤2.1％).The resistance rates of E.coli to β-lactam/β-lactam inhibitor combinations(piperacillin-tazobactam,cefoperazone-sulbactam),aminoglycosides(amikacin),nitrofurantoin and fosfomycin(for urinary isolates only)were all less than 10％.The resistance rate of E.coli strains to antibiotics varied with the level of hospitals and the departments where the strains were isolated,especially for cefazolin and ciprofloxacin,to which the resistance rate of E.coli strains from children in non-ICU departments was significantly lower than that of the strains isolated from other departments(P＜0.05).The E.coli isolates from ICU showed higher resistance rate to most antimicrobial agents tested(excluding tigecycline)than the strains isolated from other departments.The E.coli strains isolated from tertiary hospitals showed higher resistance rates to the antimicrobial agents tested(excluding tigecycline,polymyxin B,cefepime and carbapenems)than the strains from secondary hospitals and children's hospitals.Conclusions E.coli is an important pathogen causing clinical infection.More than half of the clinical isolates produced ESBL.The prevalence of CREco is increasing in secondary and tertiary hospitals over the 7-year period even though the overall prevalence is still low.This is an issue of concern.

Objective:To evaluate the effect of superficial temporal artery to middle cerebral artery (STA-MCA) bypass on cognitive function, cerebral perfusion, and integrity of white matter tracts by comparing cognitive function scores, fractional anisotropy (FA), time to maximum (T max), and cerebral blood flow (CBF) at different time points before and after STA-MCA bypass, and analyze the relations of cognitive function with cerebral perfusion and white matter tract integrity so as to provide evidences for treatment of moyamoya disease (MMD) patients with mild cognitive impairment. Methods:A retrospective analysis was performed; 30 MMD patients with mild cognitive impairment received STA-MCA bypass at Department of Neurosurgery, Lianyungang Hospital Affiliated to Xuzhou Medical University (Lianyungang First People's Hospital) from January 2023 to August 2024 were enrolled. Before and 1, 3, and 6 months after STA-MCA bypass, all patients accepted Montreal cognitive assessment (MoCA), CT perfusion imaging, and diffusion tensor imaging (DTI). Differences in MoCA score, CBF, T max, and FA at different time points before and after surgery were compared. Spearman rank correlation was used to analyze the correlation of MoCA score with cerebral perfusion parameters and FA. Results:(1) In these MMD patients with mild cognitive impairment, CBF 3 and 6 months after STA-MCA bypass was significantly increased compared with that before STA-MCA bypass, and CBF 6 months after STA-MCA bypass was significantly higher than that 1 and 3 months after STA-MCA bypass ( P<0.05); T max 1, 3 and 6 months after STA-MCA bypass was significantly shortened compared with that before STA-MCA bypass, and T max 6 months after STA-MCA bypass was significantly shortened than that 1 and 3 months after STA-MCA bypass ( P<0.05); FA 6 months after STA-MCA bypass was significantly increased compared with that before, and 1 and 3 months after STA-MCA bypass ( P<0.05); MoCA score 6 months after STA-MCA bypass was significantly increased compared with that before and 1 month after STA-MCA bypass ( P<0.05). (2) In MMD patients with mild cognitive impairment, the preoperative MoCA score was positively correlated with preoperative CBF and FA ( r s=0.428, P=0.018; r s=0.438, P=0.015) and negatively correlated with preoperative T max ( r s=-0.380, P=0.039); 6 months after STA-MCA bypass, the MoCA score was positively correlated with CBF and FA ( r s=0.365, P=0.047; r s=0.400, P=0.028) and negatively correlated with T max ( r s=-0.371, P=0.043). Conclusion:STA-MCA bypass can improve cerebral perfusion, white matter fiber tract repair and cognitive function in MMD patients with mild cognitive impairment, and improvement of cognitive function is related to cerebral perfusion and white matter fiber tract repair.
