Objective To compare the differences in ambulatory blood pressure monitoring(ABPM)parameters and cardiac struc-ture and function indicators in patients with essential hypertension complicated with tumor,then to summarize the relationship between tumor and blood pressure and structural and function of the heart.Methods A retrospective study was conducted to select patients with essential hypertensive admitted to the Second Hospital of Lanzhou University from January 2018 to July 2024.A total of 109 patients with tumor combined with hypertension and 98 patients with hypertension were identified.General information,ABPM parameters,and echo-cardiography results of patients in the two groups were collected,to analyze the differences in ABPM parameters and cardiac structure and function between the two groups.Results Compared with the hypertension group,the tumor combined with hypertension group had a re-duced nighttime systolic blood pressure fall rate,nighttime diastolic blood pressure fall rate,daytime and 24-hour systolic and diastolic blood pressure standard deviations,and left ventricular ejection fraction(all P＜0.05),while the left ventricular end-diastolic diameter and interventricular septum thickness were increased(all P＜0.05).Pearson correlation analysis revealed that the nighttime systolic blood pressure fall rate was negatively correlated with age,nighttime systolic blood pressure,and morning systolic blood pressure(all P＜0.05).In the tumor combined with hypertension patients,the interventricular septum thickness was positively correlated with body mass index,nighttime systolic blood pressure,nighttime diastolic blood pressure,and 24-hour diastolic blood pressure(all P＜0.05).Multi-ple linear regression analysis results indicated that tumor and increasing age were independent risk factors for the reduction in nighttime systolic blood pressure fall rate.Conclusion Compared with hypertensive patients,patients with tumor combined with hypertension ex-hibit abnormal blood pressure circadian rhythm,increased left ventricular end-diastolic diameter,thickening of the interventricular sep-tum,and reduced ejection fraction.The presence of tumor and increasing age in patients with essential hypertension are the main risk fac-tors affecting the nighttime blood pressure fall rate.

Objective To investigate the predictive value of serum interleukin-6(IL-6)and procalcitonin(PCT)levels on the prognosis of patients with acute respiratory distress syndrome(ARDS).Methods A total of 99 ARDS patients admitted to Lianyungang Hospital affiliated to Xuzhou Medical University from January 2021 to December 2023 were included in the study.According to the Berlin definition,the patients were divided into mild group(n=22),moderate group(n=42)and severe group(n=35)groups.Based on their 28-day outcomes,they were also divided into survival group(n=65)and death group(n=34).The levels of IL-6 and PCT in each group were compared.The predictive value of IL-6 and PCT for the prognosis of ARDS patients was analyzed using receiver operat-ing characteristic(ROC)curve and the area under the curve(AUC).The Kaplan-Meier method was used to plot survival curves for ARDS patients with different levels of IL-6 and PCT.Results Among the three groups with varying severity of ARDS,the severe group had the highest IL-6 and PCT levels,followed by the moderate group,and the mild group had the lowest levels.The differences among the groups were statistically significant(P＜0.05).The levels of IL-6 and PCT in the death group were significantly higher than those in the survival group,and the difference was statistically significant(P＜0.05).The AUC of IL-6 and PCT in predicting the prognosis of ARDS patients were 0.793 and 0.776,with the sensitivity of 79.4％and 94.1％,and the specificity of 70.8％and 61.5％,respective-ly.Kaplan-Meier survival curve analysis showed that when IL-6 was ≥110.700pg/ml and PCT was ≥ 1.700ng/ml,the 28-day sur-vival rate of ARDS patients was significantly lower than that of patients with IL-6＜110.700pg/ml and PCT＜1.700ng/ml(P＜0.001).Conclusion PCT and IL-6 levels have good value in predicting the short-term prognosis of ARDS patients,and can be used as effective indicators for prognosis evaluation in ARDS patients.

AIM:To investigate the roles of up-regulated inwardly rectifier potassium channel 2.1(Kir2.1)in macrophage activation and cardiac inflammatory injury,in order to clarify the mechanism of Kir2.1 regulation in inflam-matory injury and cardiac repair.METHODS:The RAW264.7 macrophages were activated by lipopolysacharide(LPS)and treated with Kir2.1 agonist zacopride or lentivirus-Kir2.1 overexpression(Kir2.1-OE).Macrophages were randomly divided into control,LPS,LPS+zacopride(or LPS+Kir2.1-OE),and LPS+zacopride+BaCl2 groups.The effects of Kir2.1-OE and AG490[Janus kinase 2(JAK2)inhibitor]on the JAK2/signal transducer and activator of transcription 3(STAT3)signaling pathway in macrophages were also investigated.The expression of CD86,interleukin-6(IL-6)and Kir2.1 in M1 macrophages was detected by RT-qPCR or immunofluorescence staining.The expression of JAK2/STAT3 molecules was detected by Western blot.The RAW264.7 macrophages were incubated with LPS,LPS+zacopride or LPS+zacopride+BaCl2 for 12 h,and then co-cultured with H9C2(2-1)cardiomyocytes for 48 h.The expression of Kir2.1,IL-4,IL-6,IL-1β,B-cell lymphoma-2(Bcl-2),Bcl-2-associated X protein(Bax),caspase-3,cleaved caspase-3,calcium/calmodulin-dependent protein kinase II(CaMKII)and p-CaMKII in cardiomyocytes was detected by Western blot.We fur-ther compared the effects of zacopride and KN-93,a known CaMKII inhibitor,on cardiac CaMKII.After being incubated with LPS for 12 h and changed the medium,RAW264.7 macrophages were co-cultured with H9C2(2-1)cardiomyocytes which was pretreated with KN-93.The cardiomyocytes were divided into control,LPS,and LPS+KN-93 groups.The ex-pression of CaMKII and p-CaMKII were detected by Western blot.RESULTS:Zacopride inhibited LPS-induced M1-type polarization of macrophages in a Kir2.1-dependent manner as showed by a significant decrease in CD86(M1-type marker)and IL-6(P<0.05).Zacopride or Kir2.1-OE inhibited LPS-induced activation of JAK2/STAT3 inflammatory signaling pathway in macrophages,with effects similar to the JAK2 inhibitor AG490.The H9C2(2-1)cardiomyocytes were co-cul-tured with M1-polarized macrophages(P<0.05).Zacopride inhibited M1 macrophage-induced inflammatory injury in car-diomyocytes,which was manifested as decreased expression of IL-1β and IL-6,increased expression of IL-4,and de-creased apoptosis.Zacopride also inhibited activation of CaMKII in a Kir2.1-dependent manner in H9C2(2-1)cells co-cultured with macrophages(P<0.05).CONCLUSION:Up-regulation of Kir2.1 may inhibit LPS-induced M1-type polar-ization of macrophages via inhibiting JAK2/STAT3 signaling pathway.Up-regulation of macrophage Kir2.1 may play a pro-tective role in cardiac repair after myocardial infarction by negative regulation of CaMKII signaling.

Objective:To develop outcome indicators for the implementation of comprehensive inter-ventions targeting the multimorbidity of myopia and obesity in children and adolescents,providing a basis for the co-prevention of multimorbidity and the outcome measurement of implementation research in children and adolescents.Methods:Based on the RE-AIM framework,a preliminary set of indicators was constructed.The Delphi method was employed,with experts scoring and providing feedback on the proposed indicators via questionnaires.After each round of consultation,expert enthusiasm index,authority coefficient,coordination degree,and consensus level were calculated.Expert opinions were col-lected and analyzed to modify,delete,or add indicators based on consultation results and screening crite-ria.Two Delphi rounds were conducted until consensus was achieved.Results:A total of 28 experts par-ticipated actually in both rounds.The Kendall's W coefficients for the two rounds of expert consultation were0.352(x2=413.952,P＜0.001)and 0.499(x2=405.044,P＜0.001),both statistically sig-nificant.The final outcome indicators for implementation research on comprehensive interventions for myopia and obesity comorbidity in children and adolescents included five primary dimensions with 13 secondary and 20 tertiary indicators.The dimension of reach included the number of children and adoles-cents involved,participant representativeness,and full-course participation representativeness.The di-mension of effectiveness included multimorbidity incidence,myopia incidence,spherical equivalent,body mass index(BMI),overweight and obesity prevalence,waist-to-height ratio,comprehensive health knowledge score,and comprehensive health behavior score.The dimension of adoption covered school representativeness and representativeness of school nurses and teachers involved in implementation.The dimension of implementation included fidelity,content modification,and cost.The dimension of mainte-nance included individual health outcomes and organizational sustainment.Conclusion:This study developed implementation outcome indicators for comprehensive interventions targeting multimorbidity of myopia and obesity among the children and adolescents based on the RE-AIM framework.These indica-tors can serve as a reference for optimizing intervention research strategies related to common multimor-bidity among children and adolescents in China.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Ovarian immature teratoma is a relatively rare malignant ovarian tumor that predominantly occurs in children, adolescents, and young adults. In clinical diagnosis and treatment, tumor marker detection and imaging examinations serve as crucial bases for differentiating mature and immature terotomas. A comprehensive preoperative evaluation followed by the selection of an appropriate surgical approach and extent is key to improving prognosis. Some studies have indicated that for stage Ⅰ ovarian immature teratoma, avoiding adjuvant chemotherapy under close follow-up does not increase the risk of recurrence or affect long-term survival of patients; however, for advanced-stage ovarian immature teratoma, standardized postoperative chemotherapy is still recommended. Some patients may experience benign-malignant transformation of malignant germ cell components after surgery, such as growing teratoma syndrome or squamous cell carcinoma transformation. Due to the rarity of ovarian immature teratoma, current understanding of its pathogenesis and clinical management remains limited. This paper provides a review focusing on key clinical issues related to ovarian immature teratoma and proposes corresponding diagnostic and therapeutic recommendations, aiming to offer references for promoting multidisciplinary collaboration and individualized treatment.

Objective:To investigate the potential characteristic manifestations and application value of the Dynamic Visual Acuity Test（DVAT） in vestibular migraine（VM）. Methods:A total of 50 VM patients（case group） and 50 healthy subjects（control group） diagnosed at the Department of Otorhinolaryngology Head and Neck Surgery, First Hospital of Shanxi Medical University between November 1, 2023, and December 31, 2024, were enrolled. The case group underwent DVAT, video head impulse test（vHIT）, caloric test, and Dizziness Handicap Inventory（DHI） assessment, whereas the control group only received DVAT. Group-based analyses were conducted to examine the effect of age on Dynamic Visual Acuity Loss（DVALoss）, as well as the correlations of DVALoss with vestibular function tests and DHI scores. Results:DVALoss in the case group was significantly higher than that in the control group（P<0.001）. In both groups, age was significantly and positively correlated with DVALoss（P<0.001）. Within the case group, DVALoss was strongly and positively correlated with DHI scores（r=0.807, P<0.001）; it was negatively correlated with the vestibulo-ocular reflex（VOR） gain in vHIT, though without clinical significance, and showed no significant association with the caloric test. Age and DVALoss collectively accounted for 71.3% of the variance in DHI scores（R²=0.713）, with age exerting a relatively minor actual impact. Conclusion:DVAT can sensitively identify the core functional impairments of VM. DVALoss, as a direct functional reflection of the pathological mechanism of VM, is strongly correlated with DHI scores. Incorporating DVALoss into standardized assessments may provide an objective basis for the diagnosis and management of VM.

Intestinal fibrosis is a significant clinical challenge in inflammatory bowel diseases, but no effective anti-fibrotic therapy is currently available. Glucagon receptor (GCGR) and glucagon-like peptide 1 receptor (GLP1R) are both peptide hormone receptors involved in energy metabolism of epithelial cells. However, their role in intestinal fibrosis and the underlying mechanisms remain largely unexplored. Herein GCGR and GLP1R were found to be reduced in the stenotic ileum of patients with Crohn's disease as well as in the fibrotic colon of mice with chronic colitis. The downregulation of GCGR and GLP1R led to the accumulation of the metabolic byproduct lactate, resulting in histone H3K9 lactylation and exacerbated intestinal fibrosis through epithelial-to-mesenchymal transition (EMT). Dual activating GCGR and GLP1R by peptide 1907B reduced the H3K9 lactylation in epithelial cells and ameliorated intestinal fibrosis in vivo. We uncovered the role of GCGR/GLP1R in regulating EMT involved in intestinal fibrosis via histone lactylation. Simultaneously activating GCGR/GLP1R with the novel dual agonist peptide 1907B holds promise as a treatment strategy for alleviating intestinal fibrosis.
