ObjectiveTo investigate the epidemiological and clinical characteristics of psittacosis cases in Fuyang District of Hangzhou, Zhejiang Province, and to provide evidence for clinical diagnosis, treatment, and prevention and control of this disease. MethodsEpidemiological investigation data and clinical records of psittacosis cases residing in Fuyang District of Hangzhou from September 2020 to February 2025 were collected. Descriptive epidemiological methods were applied to analyze temporal-spatial-demographic distribution characteristics, exposure history, clinical manifestations, diagnosis, treatment and laboratory findings. Comprehensive analyses were further conducted incorporating environmental surveillance and case follow-up data. ResultsAmong the 16 psittacosis cases, the male-to-female ratio was 1∶1, with an incidence rate of 0.57/100 000 for both males and females. The mean age was (59.88±10.66) years old, and the highest incidence rates were in the 70‒79 years and 60‒69 years age groups, with an incidence rate of 1.41/100 000 and 1.30/100 000, respectively. Fourteen cases (87.50%) had a history of avian exposure. The predominant clinical symptoms included fever (15 cases, 93.75%), cough (11 cases, 68.75%), expectoration (9 cases, 56.25%), and fear of cold (8 cases, 50.00%). All cases showed elevated levels of C-reactive protein (CRP), and the results of chest computed tomography (CT) indicated pneumonia in every case. Neutrophil percentage was elevated in 87.50% (14/16) of cases, while lymphocyte percentage was reduced in 93.75% (15/16) of cases. The median time from onset to first medical consultation was 4.00 days, the median time from onset to confirmed diagnosis was 9.50 days, and the median time of hospitalization was 9.00 days. Compared with non-severe cases, the severe group had significantly higher neutrophil percentage, CRP levels, and longer intervals from onset to confirmed diagnosis, onset to first antibiotic administration, and duration of hospitalization. All cases recovered and were discharged, and more than 50% were treated with omadacycline following confirmed diagnosis. ConclusionMost psittacosis cases reported definitive avian exposure history in Fuyang District of Hangzhou. Early diagnosis and treatment are critical for preventing disease progression to severe stages.

Objective:To explore the core dimensions of adolescent anxiety and their relationship with parental rearing styles and perceived social support using network analysis.Methods:A total of 3 712 adolescents were in-vestigated.The Screen for Child Anxiety Related Emotional Disorders,the Short-form Egna Minnenav Barndoms Uppfostran for Chinese,and the Perceived Social Support Scale were used to assess the anxiety levels,parental rea-ring styles,and perceived social support.Network analysis and gender network comparison were conducted using R programming language.Results:The network analysis model showed that generalized anxiety and somatization/pan-ic anticipation had the highest Expected Influence of 1.21 and 1.12,which were the two core dimensions of adoles-cent anxiety levels.The affective warmth in parental rearing styles had a Bridge Expected Influence index of 0.34,making it a bridging node in the network.The network comparison result indicated that there were significant struc-tural gender differences in the adolescent anxiety-parenting style-perceived social support network(P＜0.05),but there was no significant gender difference in global strength(P＞0.05).Conclusion:Interventions targeting adoles-cent anxiety should prioritize generalized anxiety and somatization/panic.Emotional warmth in parenting serves as a bridge connecting adolescent anxiety with perceived levels of social support.

Objective To investigate the protective effects of mitochondrial preconditioning in pericytes(PC)against pulmonary vascular leakage in septic rats.Methods ① 128 specific-pathogen-free SD rats(equal gender,200±20 g)were randomized into:Sham group(postoperative tail vein injection of 0.5 mL saline),Sepsis(Sep)group(CLP+saline),PC group(CLP+untreated PC:106 cells/rat),and Mito-PC group(CLP+PC preconditioned with 2 μg mitochondria/104 cells for 12 h).Assessments included:PC lung colonization(flow cytometry),pulmonary barrier function(Evans blue assay),lung histopathology(HE staining),serum organ injury markers[cTnT(cardiac),urea/creatinine(renal)],and inflammatory cytokines(TNF-α,IL-6).② MSC-derived mitochondria were validated by electron microscopy/flow cytometry;primary retinal PCs from weaned SD rats were purity-verified(confocal microscopy).In vitro groups:Control(PC),Mito-PC,PC+H2O2(0.5 μmol/L,4 h),and Mito-PC+H2O2.Antioxidant capacity was assessed via pentose phosphate pathway(PPP)activity,NADPH levels,G6PD activity,and NADP+/NADPH ratio.Results① Compared with Sham,Sep group showed significant increase in pulmonary leakage(Evans blue P<0.05),severe lung injury,elevated serum markers(TNF-α,IL-6,cTnT,urea,creatinine all P<0.05),0％72 h survival.PC group showed partial improvement(P<0.05).Mito-PC group demonstrated significant reduction in vascular leakage(P<0.05 vs PC group),improved histopathology and organ function(P<0.05),attenuated inflammation(P<0.05),higher 72 h survival rate(P<0.05).② Mitochondrial preconditioning significantly enhanced PPP activation and NADPH-mediated antioxidative capacity,Mito-PC+H2O2 vs PC+H2O2 showed improved cell viability(P<0.05),Mito-PC vs PC showed increased G6PD activity(P<0.05),decreased NADP+/NADPH ratio(P<0.05).Conclusion Mitochondrial preconditioning potentiates pericyte-mediated protection against sepsis-induced pulmonary vascular leakage through enhanced pentose phosphate pathway activity.Mitochondrial preconditioning potentiates pericyte-mediated protection against sepsis-induced pulmonary vascular leakage through enhanced pentose phosphate pathway activity.

Objective To assess the incidence of contrast-induced nephropathy(CIN)in patients with chronic thromboembolic pulmonary hypertension(CTEPH)after receiving balloon pulmonary angioplasty(BPA),and to evaluate the effect of the contrast agents on renal function.Methods A total of 143 CTEPH patients,who received BPA at the China-Japan Friendship Hospital of China from December 2018 to May 2022,were enrolled in this study.The clinical data,hemodynamic indicators,and serum creatinine(SC)concentrations within one week before and 48-72 h after BPA were collected.The estimated glomerular filtration rate(eGFR)was calculated according to the Modification of Diet in Renal Disease(MDRD)formula.The SC concentration and eGFR changes before and after each BPA procedure were compared.The incidence of CIN and its risk factors were evaluated,and the changes in hemodynamics,SC and eGFR after the initial and last time of BPA treatment were analyzed.Results A total of 192 BPA procedures were performed in 115 CTEPH patients,including 88 BPA procedures in males and 103 BPA procedures in females.The mean amount of contrast agent used for each BPA was(145.58±47.26)mL.After BPA,12 patients developed 13 times of CIN,with an incidence of 6.8％.There was no significant differences(P＞0.05)in the baseline characteristics and SC concentration before BPA between CIN patients and non-CIN patients.In terms of the hemodynamic indexes,the mixed venous oxygen saturation(SvO2)in CIN patients was significantly lower than that in non-CIN patients(58.58％±10.38％vs.66.15％±8.02％,P=0.002),and no statistically significant differences(P＞0.05)in the other hemodynamic indexes existed between CIN group and non-CIN group.No statistically significant differences in SC concentration and eGFR existed before and after each BPA procedure.In patients who had received several BPA procedures,significant improvements in the SC[(78.09±18.760)μmol/L vs.(82.26±21.37)μmol/L,P＜0.001]and eGFR[(86.08±21.22)mL/(min·1.73 m2)vs.(82.07±22.05)mL/(min·1.73 m2),P=0.007]was achieved when compared with their baseline values.Conclusion CTEPH patients may develop CIN after receiving BPA treatment.After receiving several BPA treatments the patient's clinical symptoms and hemodynamics can be improved,and the patient's renal function is also significantly improved.
