This article reported a pregnant woman admitted to the hospital due to "25 +2 weeks of amenorrhea and a 1-day history of shortened cervical canal accompanied by vaginal bleeding". The patient with pregestational diabetes mellitus and suboptimal glycemic control required prolonged hospitalization for tocolytic therapy due to shortened cervical length. She developed a cough at 31 weeks and 4 days of gestation, followed by right-sided intercostal pain and hypotension after coughing at 31 weeks and 6 days of gestation. Bedside chest ultrasound showed a small anechoic fluid collection (approximately 1.1 cm in width) in the right pleural cavity. The emergency cesarean section was performed at 31 weeks and 4 days of gestation. However, the intraoperative bleeding and other conditions were inconsistent with the obstetric clinical presentations of blood loss. Subsequent repeated ultrasound and CT examinations confirmed the diagnosis of pulmonary sequestration and right-sided progressive hemopneumothorax. On the same day, an emergency right lower lobectomy was performed, achieving stable postoperative recovery. Both mother and infant had favorable outcomes. Hemopneumothorax complicated by pulmonary sequestration is uncommon, and its occurrence during pregnancy is exceedingly rare. Multidisciplinary consultations, aggressive, rapid, and accurate diagnosis, and combined treatment are critical to ensuring maternal-fetal survival. Hemopneumothorax caused by the rupture of pulmonary sequestration during pregnancy represents a life-threatening condition. Emergency thoracotomy can timely clarify the cause, arrest bleeding, relieve compression, and resect the lesion, thereby reducing mortality and the complications risk.

Objective:This study aims to provide insights into the clinical features of anti-melanoma differentiation-associated protein-5(MDA5)-positive dermatomyositis (MDA5-DM) patients with fatal outcomes, leveraging pathogenic microbiota metagenomic analysis, to guide the clinical assessment and treatment choices.Methods:From January 2020 to August 2023, deceased patients diagnosed with MDA5-DM were identified at the Department of Rheumatology and Immunology, the Second Affiliated Hospital of Xi ′an Jiaotong University. Clinical data were retrospectively collected and analyzed using Mann Whitney U test and Fisher ′s exact test to summarize risk factors and treatment assessment for MDA5-DM patients with fatal outcomes. Results:①The proportion of male patients was higher than females among MDA5-DM patients with fatal outcomes, which differed from the incidence pattern, possibly associated with smoking and gender proportions (6/11 vs. 0/7, P=0.037). ②94%(17/18) patients presented initially with elevated ferritin levels [(1 350±942)ng/ml] and CRP [(47±36)mg/L]. ③All patients (18/18) exhibited early involvement of the upper lung lobes, including multiple nodules in 9/18, ground-glass opacities in 5/18, and solitary nodules in 4/18. ④Metagenomic next-generation sequencing (mNGS) of bronchoalveolar lavage fluid was negative in 4/16 cases, with cytomegalovirus and pneumocystis jirovecii being the most commonly detected pathogens in 5/16 cases each. ⑤89%(16/18) of patients continued to have lymphocyte counts persistently <0.5×10 9/L irrespective of treatment. Conclusion:Smoking may have adverse effects on male MDA5 patients. Early involvement of the upper lobe of the lungs is more common in MDA5 antibody positive deaths, and persistent lymphocyte depletion is an important factor in poor response. Enhancing mNGS analysis of bronchoalveolar lavage fluid and vigilance towards cytomegalovirusand Pneumocystis jirovecii could provide valuable clinical guidance.

Objective To investigate the relationships of the expression of serum matrix metalloproteinase-9 (MMP-9), soluble urokinase type plasmin activator receptor (suPAR) and plasmin activator inhibitor-1 (PAI-1) with the cardiac function grading and prognosis in elderly patients with chronic heart failure (CHF). Methods A total of 108 CHF patients and 50 healthy individuals with physical examination in the same period in Langfang City Hospital of Traditional Chinese Medicine were respectively selected as study group and control group. The blood samples were collected for detection of serum levels of MMP-9, suPAR and PAI-1. The differences in serum indicators among patients with different cardiac functional grades of the New York Heart Association (NYHA) and different prognoses were compared, and the predictive values of serum indicators for poor prognosis were analyzed as well. Results Compared with the control group, the serum levels of MMP-9, suPAR and PAI-1 in the study group were significantly higher (P < 0.05). The levels of serum MMP-9, suPARand PAI-1 increased gradually and significantly in patients with the increase of NYHA grading as grade Ⅱ, grade Ⅲ and grade Ⅳ (P < 0.05). The results of the one-year follow-up showed that there were 65 cases with good prognosis and 43 cases with poor prognosis, and the poor prognosis rate was 39.81% (43/108). Compared with patients of good prognosis, patients with poor prognosis had higher age, higher incidence of complicated hypertension, lower left ventricular ejection fraction (LVEF), and higher levels of left ventricular end diastolic diameter (LVEDD), MMP-9, suPAR and PAI-1 (P < 0.05). Logistic regression analysis showed that age, MMP-9, suPAR and PAI-1 were the risk factors for poor prognosis in elderly patients with CHF, while LVEF was a protective factor for poor prognosis in elderly patients with CHF (P < 0.05). The area under the curve (AUC) of serum MMP-9, suPAR and PAI-1 detected separately and in combination were 0.711, 0.829, 0.768 and 0.840 respectively, the sensitivity and specificity of the three indexes in combination were 88.21% and 79.46% respectively. Conclusion The expression levels of serum MMP-9, suPAR and PAI-1 in elderly patients with CHF are closely related to thecardiac functional grading and poor prognosis.

Objective To investigate the expression levels of serum insulin-like growth factor binding protein-7 (IGFBP-7) and silence-information regulatory factor 4 (SIRT4) in patients with acute heart failure (AHF) and their prognostic value. Methods A total of 151 patients with AHF (AHF group) and 151 healthy subjects (control group) were enrolled. Serum IGFBP-7, SIRT4, N-terminal natriuretic peptide precursors (NT-proBNP) and reactive oxygen species (ROS) were detected in the two groups. The relationships of serum levels of IGFBP-7, SIRT4, NT-proBNP, ROS with clinical grade were analyzed. Pearson correlation coefficient was used to analyze the correlations of IGFBP-7 and SIRT4 with NT-proBNP and ROS. Multivariate Logistic regression analysis was used to analyze the prognostic factors of AHF patients, and the Receiver operating characteristic (ROC) curve was drawn to analyze the predictive efficacy of serum IGFBP-7 and SIRT4 on poor prognosis of AHF patients. Results Compared with the control group, the expression levels of IGFBP-7, SIRT4, NT-proBNP and ROS in serum of the AHF group were significantly increased (P < 0.05). The expression levels of IGFBP-7, SIRT4, NT-proBNP and ROS in the serum of patients with clinical disease grade Ⅳ were higher than that in grade Ⅲ and grade Ⅱ, and those with grade Ⅲ was significantly higher than that of grade Ⅱ (P < 0.05). The expression levels of IGFBP-7, SIRT4, NT-proBNP and ROS and severity grading in patients with poor prognosis in the AHF group were significantly higher than those in patients with good prognosis (P < 0.05). The expression levels of IGFBP-7 and SIRT4 in serum were positively correlated with the levels of NT-proBNP and ROS (r=0.523, 0.498, 0.578, 0.557, P < 0.05). Multifactor Logistic regression analysis showed that clinical grade, serum expression levels of IGFBP-7, SIRT4, NT-proBNP and ROS were independent influencing factors for prognosis of AHF (P < 0.05). ROC curve analysis showed that serum IGFBP-7 and SIRT4 had a certain predictive value for prognosis in AHF patients, with AUC of 0.794 and 0.795, and the combined detection of IGFBP-7 and SIRT4 had a higher predictive value (AUC was 0.909, 95%CI, 0.858 to 0.959). Conclusion Serum IGFBP-7 and SIRT4 are highly expressed in patients with AHF, and their expression levels are correlated with clinical grade and prognosis, and the combined detection of the two indicators is of high reference value for evaluating the prognosis of patients.

ObjectiveTo observe the clinical efficacy of modified Yigongsan combined with multi-enzyme tablets and bifidobacterium triple live powder on infantile anorexia with spleen-stomach Qi deficiency syndrome. MethodA total of 112 infantile patients anorexia with spleen-stomach Qi deficiency syndrome treated at Hebei Provincial Hospital of Traditional Chinese Medicine from January 2022 to June 2023 were enrolled and divided into a control group and an observation group， with 56 cases in each group， according to a random number table. Children in the control group were treated with multi-enzyme tablets and Bifidobacterium triple live powder， while those in the observation group were treated with modified Yigongsan in addition to the treatment in the control group. During the study， one case dropped out in the control group and two cases dropped out in the observation group. The clinical efficacy of the two groups of children was compared， including changes in traditional Chinese medicine （TCM） syndrome scores （main symptoms， secondary symptoms， tongue， and pulse）， time to restore normal food intake， and increase in body weight. Changes in calcium， iron， zinc levels， hemoglobin， and albumin levels before and after treatment， as well as changes in gastrointestinal hormones such as gastrin and motilin， vasoactive intestinal peptide， somatostatin， neuropeptide Y， orexin， and leptin， were observed. The occurrence of adverse reactions in the two groups of children during the study was also recorded. ResultThe total effective rate of children in the control group after treatment was 85.19% （46/54）， while that in the observation group was 98.15% （53/54） （χ² =5.939， P<0.05）. Compared with the control group， the time for food intake to return to normal in the observation group was shorter， and the increase in body weight was greater （P<0.05）. Compared with the results before treatment， the TCM syndrome scores （main symptoms， secondary symptoms， tongue， and pulse） in both groups of children significantly decreased， while the levels of calcium， iron， zinc， hemoglobin， albumin， gastrin， motilin， neuropeptide Y， and orexin increased， and the levels of vasoactive intestinal peptide， somatostatin， and leptin decreased （P< 0.01）. Compared with the control group after treatment， the improvement in the above indicators in the observation group was more significant （P<0.01）. The incidence of adverse reactions in the two groups of children during the treatment period was similar， and the difference was not statistically significant. ConclusionModified Yigongsan combined with multi-enzyme tablets and Bifidobacterium triple live powder is highly effective in treating infantile anorexia （spleen-stomach Qi deficiency syndrome）. After treatment， symptoms of the children were improved，appetite and food intake increased， gastrointestinal function was improved， body weight increased， and adverse reactions were few， indicating that the treatment was safe and reliable.

Objective:To investigate the impact of the interval period between biopsy and MR examination on tumor detection and extraprostatic extension (EPE) assessment for prostate cancer (PCa) using multi-parametric MRI (mpMRI).Methods:The study was cross-sectional and retrospectively included 130 patients with PCa who underwent RP and preoperative systematic biopsies followed by mpMRI between January 2021 and December 2022 in the First Medical Center of Chinese PLA General Hospital. Patients were divided into 3 groups according to interval following biopsy (group A,<3 weeks, 31 cases; group B, 3-6 weeks, 67 cases; group C,>6 weeks, 32 cases). The percentages of hemorrhage volume in the total prostate were drawn on T 1WI and calculated. The junior, senior and expert radiologists independently localized the index lesions and calculated the accuracy for tumor detection, in addition to assessing the probabilities of EPE according to EPE grade. The correlation between the hemorrhage extent and interval was analyzed using the Spearman correlation coefficient. The accuracy for tumor detection was compared using χ2 test among groups. The diagnostic performance of the radiologists for EPE prediction was assessed using the receiver operating characteristic curve, and the differences between the corresponding area under the curve (AUC) were compared using the DeLong test. Results:The percentage of hemorrhage was correlated with the interval between biopsy and MR examination ( r=-0.325, P<0.001). The detection accuracy of junior radiologist was 83.9% (26/31), 76.1% (51/67), and 78.1% (25/32) in group A, B and C, respectively; no differences were observed in the detection accuracy among three groups ( χ2=0.76, P=0.685). The detection accuracy of senior radiologist was 83.9% (26/31), 80.6% (54/67), and 71.9% (23/32) in 3 groups with no differences ( χ2=1.53, P=0.464). The detection accuracy of expert radiologist was 80.6% (25/31), 77.6% (52/67), and 93.8% (30/32) with no differences ( χ2=3.95, P=0.139). The AUC (95% CI) for predicting EPE were 0.830 (0.652-0.940), 0.704 (0.580-0.809), 0.800 (0.621-0.920) in the group A, B and C for junior radiologist; 0.876 (0.708-0.966), 0.768 (0.659-0.863), 0.896 (0.736-0.975) for senior radiologist; and 0.866 (0.695-0.961), 0.813 (0.699-0.895), 0.852 (0.682-0.952) for expert radiologist, respectively. No differences were observed among the subgroups in each radiologist ( P>0.05). Conclusion:The interval period does not significantly affect the detection accuracy and EPE assessment of PCa using mpMRI. There is probably no necessity for prolonged intervals following systematic biopsy to preserve the clarity of MRI interpretation for PCa.

Objective To investigate the relationship between serum microRNA(miR)-137 and miR-21 ex-pression and hypertensive retinopathy(HR).Methods A total of 123 hypertensive patients admitted to the hospital from March 2020 to August 2022 were selected as the hypertensive group and divided into HR and non-HR groups according to whether they were concomitant with HR,and another 58 healthy people who un-derwent the physical examination during the same period were selected as the control group.Clinical data of HR patients were collected and serum miR-137 and miR-21 expression was detected by real-time fluorescent quantitative PCR.The influencing factors of concurrent HR in hypertensive patients were analyzed,and receiv-er operating characteristic(ROC)curve was used for analzing predictive value of serum miR-137 and miR-21 expression in hypertensive patients with concurrent HR.Results Serum miR-137 and miR-21 relative expres-sion levels were higher in the hypertensive group than those in the control group(P<0.05).The incidence rate of HR in 123 hypertensive patients was 25.20%(31/123).Multivariate Logistic regression analysis showed that prolonged duration of hypertension and elevated systolic pressure,diastolic pressure,miR-137 rel-ative expression level,and miR-21 relative expression level were independent risk factors for HR in hyperten-sive patients(P<0.05).ROC curve analysis showed that the area under the curve(AUC)of serum miR-137 combined with miR-21 in predicting HR in hypertensive patients was 0.840,which was greater than 0.735 and 0.732 of the single detection of miR-137 and miR-21(P<0.05).Conclusion High expression of serum miR-137 and miR-21 is closely associated with hypertension complicating HR and may be an auxiliary predictor of HR.
