Objective:To explore the association between sublingual microcirculatory perfusion vessel proportion (PPV), high mobility group protein B1 (HMGB1), and sepsis-induced coagulopathy (SIC), and to identify early predictive markers for clinical intervention.Methods:A total of 66 septic patients admitted to the Respiratory Intensive Care Unit (RICU) between November 2021 and May 2024 were enrolled. Based on SIC diagnosis within 24 hours of admission, patients were categorized into SIC ( n=36) and non-SIC ( n=30) groups. Clinical parameters, including prothrombin time (PT), activated partial thromboplastin time (APTT), sublingual PPV, and serum HMGB1 levels (measured at 0 h and 6 h), were analyzed. Logistic regression and receiver operating characteristic (ROC) curve analyses were performed to identify independent predictors. Results:Compared with the non-SIC group, the SIC group demonstrated significantly prolonged PT ( P<0.05) and APTT ( P<0.05), elevated 0 h lactate levels, and increased 6 h HMGB1. Spearman analysis revealed a positive correlation between 6 h PPV and platelet count ( P<0.05), while an inverse correlation was observed with 6 h PT ( P<0.05). Multivariate regression identified APTT, 6 h PPV, and 6 h HMGB1 as independent predictors of SIC. ROC analysis yielded AUC values of 0.732 for APTT, 0.802 for 6 h PPV, and 0.765 for 6 h HMGB1. The combination of 6 h PPV and HMGB1 further improved predictive accuracy (AUC=0.873). Conclusions:Prolonged APTT, decreased 6 h PPV, and elevated 6h HMGB1 are key indicators of SIC. Integrated assessment of these markers enhances early risk stratification in septic patients, facilitating timely clinical intervention.

[Objective]To evaluate the efficacy and safety of total oral regimens containing pomalidomide as a second-line treatment strategy in multiple myeloma.[Methods]A total of 22 patients with multiple myeloma placed on total oral regimens containing pomalidomide as a second-line therapy from March 2020 to December 2023 were retrospectively analyzed to evaluate the treatment response,survival and safety.[Results]The median age of the 22 patients was 71.5 years old. The total oral treatment regimens containing pomalidomide included IPD (7 cases),PCD (11 cases),XPD (2 cases),and PD (2 cases). The median number of treatment cycles was 14. Among the 13 patients with prior lenalidomide exposure,ORR was 53.85％,of which 23.08％ was ≥VGPR. In 9 patients without prior lenalidomide exposure,the ORR was 77.78％,and of which 55.56％ was ≥VGPR. There was no significant difference in ORR between these two groups (P=0.38). In 12 patients with high genetic risk,the ORR was 50％,and ≥VGPR was 16.67％. The median follow-up time was 10.6 months. Disease progressed in 10 patients and death occurred in 6 patients of them. The median progression free survival (PFS) was not reached (not reached and 10.6 months in non-lenalidomide-exposure patients or lenalidomide-exposure patients,respectively).The high grade treatment-related adverse events (AEs)(≥3 ) were reported in 18.18％ patients,including granulocytopenia,thrombocytopenia,and pulmonary infection. There was no treatment-related death.[Conclusion]Total oral regimens containing pomalidomide as a second-line therapy is generally effective and safe for multiple myeloma patients.

Purpose To summarize the clinical and imaging features of neonatal herpes simplex encephalitis(NHSE).Materials and Methods Clinical and imaging data of 5 NHSE from January 2016 to June 2023 in Beijing Children's Hospital,Capital Medical University were retrospectively collected.All five children underwent MRI examinations,with three of them undergoing enhanced scanning simultaneously.Two children had previously undergone CT scans.The location,density/signal,enhancement characteristics as well as follow-up imaging changes of the lesions were reviewed.Results The main clinical manifestations of NHSE were fever(5 cases)and seizure(4 cases),sometimes accompanied by herpes(2 cases).Imaging examinations in NHSE typically presented with symmetric(1 case)or diffuse/multifocal(4 cases)lesions in bilateral cerebral hemispheres,along with involvement of the bilateral thalamus(5 cases).Early CT scans showed either no abnormalities(1 case)or extensive areas of low density(1 case).MRI examinations usually demonstrated restricted diffusion of acute phase lesions(3 cases)and significant leptomeningeal enhancement in affected areas(3 cases).Intracranial lesions often led to the diffuse atrophy of brain parenchyma and polycystic encephalomalacia(3 cases),indicating a poor prognosis.Conclusion The clinical manifestations of NHSE are nonspecific.Early MRI examinations are of great value for accurate diagnosis and disease evaluation.

Objective To explore the association between peripheral retinal defocus and myopia in adolescents.Methods This study encompassed 192 adolescents(192 right eyes),aged between eight and fifteen years,who sought treatment at Ineye Hospital of Chengdu University of TCM from October 2022 to April 2023.Based on the spherical equiva-lent(SE),the patients were divided into three groups:Emmetropia(E),low myopia(LM),and moderate myopia(MM),with each group comprising 64 patients(64 right eyes).After mydriatic refraction,the SE values were documen-ted.Ocular biological parameters,including axial length(AL),central corneal thickness(CCT),lens thickness(LT),and keratometry values(K1,K2),were obtained using IOL Master 900.Multispectral refraction topography was employed to measure the retinal defocus:positive values indicated hyperopic defocus,while negative ones represented myopic defocus.With the macular fovea as the center,the total retinal defocus value was recorded as TRDV.The ring partition(eccentrici-ty)was divided into 0°-10°、＞10°-20°、＞20°-30°、＞30°-40°、＞40°-53°,which was recorded as RDV-0°-10°,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,and RDV-40°-53°,respectively;the quadrants were recorded as RDV-Superior(RDV-S),RDV-Inferior(RDV-I),RDV-Temporal(RDV-T)and RDV-Nasal(RDV-N),respectively.The variance of RDV across different ranges was analyzed using One-Way ANOVA and non-parametric tests.The associations between SE,AL and RDV were examined using Spearman and Pearson correlation analyses.Results The RDV-20°-30°,RDV-30°-40° and RDV-40°-53° of Groups E,LM and MM all exhibited hyperopic defocus.Statistically significant differences were identi-fied in TRDV,RDV-10°-20°,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T and RDV-N among the three groups(all P＜0.05).TRDV,RDV-20°-30°,RDV-30°-40°,RDV-40°-53°,RDV-S,RDV-T,and RDV-N were found to be negatively correlated with SE while positively correlated with AL(all P＜0.05).RDV-0°-10° and RDV-I were uncorrelated with both SE and AL(all P＞0.05);RDV-10°-20° was positively correlated with AL(P=0.012)while uncorrelated with SE(P=0.233).Conclusion Peripheral retinal hyperopic defocus tends to advance with escalating eccentricity and my-opia.Peripheral retinal defocus is asymmetrical.Peripheral(10°-53°),superior,nasal and temporal retinal defocus may be closely related to the development of myopia.

Objective To systematically evaluate brain parenchymal and vascular changes after neonatal arterial ischaemic stroke(AIS)using nonenhanced brain neurovascular MR sequences.Methods MR imaging data of 57 children with AIS(＜28 days old at the time of diagnosis)were analyzed retrospectively,including[susceptibility weighted imaging(SWI),magnetic resonance angiography(MRA),magnetic resonance venography(MRV)]sequences and conventional brain sequences[T1 WI,T2 WI,diffusion weighted imaging(DWI)].The imaging features and alteration trend of different sequences in different periods were summarized and studied.Results Vessels increased or decreased in number and enlarged or reduced in diameter within the infarction area,which presented a mixed-pattern,while the periphery showed increased only by using the nonenhanced brain vascular sequence.During the first 9 days after the onset of symptoms,the signals of T1 WI and T2 WI within the infarction area gradually stabilized,and most signals of DWI returned to normal.MRA,MRV,and SWI sequences showed a minimal change of diameter and number of vessels within the infarction area and its surroundings,which directed that neonatal AIS may had transient and dramatic brain injury and blood flow alteration.Conclusion The nonenhanced neurovascular sequence of brain MR can comprehensively display the alteration of brain parenchymal signals and vascular trends after neonatal AIS,providing the possibility for early clinical rapid and effective evaluation.

Objective:To explore the impact of Cox interaction model of client health behavior (IMCHB) on stress response and rehabilitation outcome in patients undergoing coronary artery bypass graft, and to provide reference for caregivers to reduce stress response in such patients and improve rehabilitation outcomes.Methods:This was a quasi-experimental study, and 62 surgical patients undergoing coronary artery bypass graft in the cardiac surgery department of the First Affiliated Hospital of Xinjiang Medical University were selected from January to June 2023.Among them, 31 patients admitted from January to March 2023 were in the control group, and routine nursing measures were taken; 31 patients admitted from April to June 2023 were in the intervention group with IMCHB nursing based on this routine nursing. The anxiety, depression, quality of life, hemodynamic indicators, postoperative activity time, evacuation time, pericardial/mediastinal drainage time, ICU stay length and total hospitalization length between the two groups were compared.Results:There were 31 cases were admitted in each group. There were 28 males and 3 females,aged (57.42 ± 7.38) years old in the control group. There were 27 males and 4 females, aged (56.29 ± 7.29) years old in the intervention group. After intervention, the total score of anxiety and depression and SF-36 in the intervention group were respectively (16.87 ± 4.83) points and (78.32 ± 13.41) points, and the control group were (20.81 ± 6.35) points and (69.97 ± 11.37) points, respectively, and the differences between the two groups were statistically significant ( t=2.75, -2.65, both P<0.05). Immediately after completion of cardiopulmonary bypass (T3), the mean arterial pressure in the intervention group was (85.55 ± 8.46) mmHg (1 mmHg=0.133 kPa), higher than (74.33 ± 17.40) mmHg in the control group, heart rate was (77.72 ± 10.97) times/min, lower than (88.35 ± 15.96) times/min in the control group. At the beginning of cardiopulmonary bypass (T2), and when leaving the operation room (T4), the heart rate of patients in the intervention group was (69.50 ± 10.94), (81.11 ± 10.22) times/min, significantly lower than (77.98 ± 14.51), (90.47 ± 15.44) times/min in the control group, the differences were statistically significant ( t values were -3.23 to 3.06, all P<0.05). In the intervention group, first ambulation, exhaust, pericardial/mediastinal drain retention, ICU stay, total hospitalization were (7.48 ± 2.83), (3.06 ± 0.99), (6.52 ± 2.39), (5.35 ± 3.20), (28.90 ± 5.63) d, all were significantly lower than (12.81 ± 4.84),(4.55 ± 1.65), (8.87 ± 3.30), (12.74 ± 7.31), (35.94 ± 8.82) d in the control group with statistical differences ( t values were 3.21-5.29, all P<0.05). Conclusions:The application of Cox health behavior interaction mode can reduce the anxiety and depression in coronary artery bypass graft patients, improve the quality of life, reduce the stress response of patients, and improve the rehabilitation outcomes.
