Patients with Takayasu arteritis combined with aortic valve disease often have a poor prognosis following surgical valve replacement, frequently encountering complications such as perivalvular leakage, valve detachment, and anastomotic aneurysm. This article presents a high-risk case wherein severe aortic valve insufficiency associated with Takayasu arteritis was successfully managed through transcatheter aortic valve implantation via the transapical approach. The patient had satisfactory valve function with no complications observed during the six-month postoperative follow-up. This case provides a minimally invasive and feasible alternative for the clinical management of such high-risk patients.

Objective To investigate the correlation between changes in the inner retinal irregularity index(IRII)af-ter macular epiretinal membrane(ERM)stripping and visual function in patients with idiopathic macular epiretinal mem-brane(IMEM).Methods A retrospective analysis was conducted on the clinical data of 134 patients(162 eyes)with IMEM who visited our hospital from March 2022 to December 2024.Based on fundus color photography and OCT findings,the patients were divided into the cellophane macular reflex(CMR)group and the preretinal macular fibrosis(PMF)group.Differences in central macular thickness(CMT),best-corrected visual acuity(BCVA),inner retinal thickness(IRT),and IRII were analyzed between the two groups.The diagnostic efficacy of these indicators for IMEM at admission was analyzed using receiver operating characteristic(ROC)curves.The differences in visual function indicators and IRII before and 3 months after ERM stripping were compared in IMEM patients.The correlation between IRII levels and visual function parameters at 3 months postoperatively was analyzed using Pearson correlation analysis.Results Among the 134 patients(162 eyes)with IMEM,93 patients(103 eyes)were in the CMR group and 41 patients(59 eyes)were in the PMF group.The CMT,IRT,and IRII were significantly lower in the CMR group than in the PMF group(all P＜0.05).The areas under the curve(AUC)for CMT,IRT,and IRII were 0.616,0.609,and 0.862,respectively(all P＜0.05).Among the 134 patients(162 eyes)with IMEM,79 patients(86 eyes,53.86％)underwent surgical treatment,and 55 patients(76 eyes,46.91％)received non-surgical treatment.Three months after surgery,the CMT,IRT,and IRII in IMEM patients were sig-nificantly lower than those before surgery(all P＜0.05).At 3 months postoperatively,CMT and IRT were significantly pos-itively correlated with IRII in IMEM patients(all P＜0.05).Conclusion CMT,IRT,and IRII all have good diagnostic ef-ficacy for IMEM staging.Moreover,IRII changes in IMEM patients who underwent macular ERM stripping are positively correlated with visual function.

Objective:To evaluate the role of NOD-like receptor protein 3 (NLRP3) inflammasome-mediated microglia activation in myocardial ischaemia-reperfusion-induced brain injury in mice.Methods:Fifty-two SPF healthy male wild-type C57BL/6 mice and 52 NLRP3 -/- mice, aged 8-10 weeks, were divided into 4 groups ( n=26 each) using a random number table method: wild type sham operation group (W-S group), wild type myocardial ischemia-reperfusion group (W-IR group), NLRP3 -/- sham operation group (NLRP3 -/--S group), and NLRP3 -/- myocardial ischemia-reperfusion group (NLRP3 -/--IR group). The myocardial ischemia-reperfusion-induced brain injury model was established by ligating the left anterior descending coronary artery for 45 min followed by 24 h of reperfusion in anesthetized mice. The cognitive function was evaluated using the modified Morris water maze test at 24 h of reperfusion. The mice were sacrificed after blood specimens were collected, and brain tissues were obtained for measurement of the blood-brain barrier permeability and water content, for microscopic examination of the pathological changes of brain tissues, and for determination of serum S-100β protein and neuron-specific enolase (NSE) concentrations, contents of interleukin-1 beta (IL-1β), IL-6 and tumor necrosis factor-alpha (TNF-α) in hippocampal tissues (by enzyme-linked immunosorbent assay), expression of NLRP3, apoptosis-associated speck-like protein (ASC), cleaved cysteine aspartate protease 1 (cleaved-caspase-1), gasdermin D (GSDMD), ionized calcium-binding adapter molecule 1 (Iba-1), and occludin in hippocampal tissues (by immunofluorescence and/or Western blot). The apoptosis rate of neurons and density of dendritic spine were calculated. Results:Compared with sham operation group, the escape latency was significantly prolonged, the number of crossing the original platform was decreased, and the time spent in the target quadrant was shortened, the concentrations of serum S-100β protein and NSE were increased, the blood-brain barrier permeability and brain water content were increased, the dendritic spine density in the hippocampal CA1 area was decreased, the contents of IL-1β, IL-6 and TNF-α were increased, the expression of NLRP3, ASC, cleaved-caspase-1, GSDMD and Iba-1 was up-regulated, and the expression of occludin was down-regulated ( P<0.05), and the pathological injury to brain tissues was found in ischemia-reperfusion group. Compared with W-IR group, the escape latency was significantly shortened, the number of crossing the original platform was increased, and the time spent in the target quadrant was prolonged, the concentrations of serum S-100β protein and NSE were decreased, the blood-brain barrier permeability and brain water content were decreased, the dendritic spine density in the hippocampal CA1 area was increased, the contents of IL-1β, IL-6 and TNF-α were decreased, the expression of NLRP3, ASC, cleaved-caspase-1, GSDMD and Iba-1 was down-regulated, and the expression of occludin was up-regulated ( P<0.05), and the pathological injury to brain tissues was alleviated in NLRP3 -/--IR group. Conclusions:NLRP3 inflammasome-mediated microglia activation is involved in myocardial ischaemia-reperfusion-induced brain injury in mice.

To analyze all-cause mortality among hepatitis C cases aged ≥18 years in Yuxi City from 2005 to 2023 and explore the interactions of factors influencing survival time. Baseline and follow-up data for hepatitis C cases reported during this period were extracted from the Chinese National Notifiable Disease Reporting System. Survival time and related factors were assessed using the Cox proportional hazards model. Kaplan-Meier cumulative mortality risk curves were generated for treated and untreated hepatitis C cases, and interactions among subgroups of various influencing factors were examined. A total of 5 110 hepatitis C cases aged ≥18 years were reported from 2005 to 2023, encompassing 35 349.25 person-years of observation with the follow-up time duration M ( Q1, Q3) was 6.17 (2.33, 11.08) person-years. There were 763 all-cause deaths, corresponding to a mortality density of 2.16 per 100 person-years. Survival analysis showed a statistically significant difference in cumulative mortality between the treated and untreated groups (Log-rank χ2=122.033, P<0.001), with a lower risk of death observed among treated patients. Additive model analysis showed that there was a synergistic interaction between treatment status and age group, with relative excess of interaction, attributable proportions of interaction, and synergy index of 6.16 (95 %CI: 2.70-9.61), 1.83 (95 %CI: 1.46-2.30), and 0.42 (95 %CI: 0.31-0.53), respectively; and between treatment status and gender. There was a synergistic interaction between treatment status and sex, with relative excess of interaction, attributable proportions of interaction, and synergy index of 2.63 (95 %CI: 1.14-4.13), 1.56 (95 %CI: 1.19-2.06), and 0.32 (95 %CI: 0.17-0.46), respectively. The cause of death composition were 38.53% (249 cases) attributed to hepatitis C-related causes.The leading non-hepatitis C-related causes of death were cardiovascular and cerebrovascular diseases, pulmonary diseases, malignancies, drug overdose, and injuries. In conclusion, hepatitis C cases ≥18 years of age in Yuxi City had a lower cumulative mortality rate when treated than when untreated. Treatment status interacted with age and gender on patient survival, respectively. Changes in patients with concomitant cardiovascular diseases, pulmonary diseases and malignancies should be focused.

Objective:To explore the clinical characteristics, diagnosis, and treatment of chylous pleural effusion caused by liver cirrhosis.Methods:The clinical data of 19 cases of liver cirrhosis complicated with chylous pleural effusion admitted at Department of Lymphatic Surgery, Beijing Shijitan Hospital from Jun 2013 to Oct 2022 was retrospectively analyzed.Results:There were 12 males (63.2%) and 7 females (36.8%).Ten cases (52.6%) had right chylothorax, and 9 cases (47.4%) had bilateral chylothorax; Seventeen cases (89.5%) had concurrent ascites. Chest fluid examination: 3 cases were milky white (16%), 10 cases were yellow white (53%), 4 cases were orange yellow (21%), and 2 cases were pink (10%).There were 2 cases of exudate and 17 cases of transudate. By radionuclide lymphatic imaging, 9 cases showed increased radiation in the right chest cavity; One case showed increased radiation in the left chest cavity; Five cases showed bilateral chest radiation elevation. By lymphangiography,11 cases showed complete visualization of the thoracic duct, of which 10 cases showed obstruction at the outlet of the thoracic duct. The 10 patients underwent surgical treatment for the release of adhesions at the end of the thoracic duct, and the postoperative result was good. Six patients died during follow-up.Conclusions:Cirrhosis combined with chylous pleural effusion is rare in clinical practice and prognosis is poor. The laboratory examination of pleural effusion is an important basis for determining chylous pleural effusion. The lysis of adhesions at the end of the thoracic duct has a certain therapeutic effect on patients with lymphangiography indicating thoracic duct outlet obstruction.

Objective:To analyze the effects of low-molecular-weight heparin combined with insulin (LMWH+INS) and double filtration plasmapheresis (DFPP) on lipid profiles and clinical outcomes in patients with hypertriglyceridemic acute pancreatitis (HTG-AP) based on propensity score matching.Methods:The clinical data of 126 patients with HTG-AP from October 2022 to February 2024 in The Third Affiliated Hospital of Nanjing Medical University, Changzhou Traditional Chinese Medicine Hospital Affiliated to Nanjing Traditional Chinese Medicine University and Changzhou First People's Hospital were retrospectively included. Patients were divided into LMWH+INS group ( n=87) and DFPP group ( n=39) according to the treatment. Propensity score matching was applied at a 1∶1 ratio. The repeated measures analysis of variance was conducted to assess dynamic changes of blood lipids within the 5 days of admission between the LMWH+INS and DFPP groups after matching. Clinical symptoms and outcomes were compared between the two matched groups following matching. Results:29 patients were included in both LMWH+INS group and DFPP group after propensity score matching. No statistically significant differences were observed in triglycerides (TG), acute physiology and chronic health evaluation Ⅱ(APACHEⅡ) score, or bedside index for the severity of acute pancreatitis (BISAP) between the two groups (all P value >0.05), indicating comparability. Repeated measures analysis of variance revealed that TG and TC levels in the DFPP group were significantly lower than those in the LMWH+INS group at 2-5 days after admission [TG 2 d: (5.26±2.59) mmol/L vs (10.79±3.81) mmol/L, 3 d: (3.35±1.01) mmol/L vs (7.72±3.64) mmol/L, 4 d: (3.45±0.77) mmol/L vs (6.57±3.17) mmol/L, 5 d: (3.73±1.26) mmol/L vs (5.61±3.07) mmol/L; TC 2 d: (4.83±2.29) mmol/L vs (8.2±2.82) mmol/L, 3 d: (4.23±2.17) mmol/L vs (7.71±2.68) mmol/L, 4 d: (4.28±1.59) mmol/L vs (7.55±2.41) mmol/L, 5 d: (4.1±1.21) mmol/L vs (7.84±2.6) mmol/L], with a more rapid decrease. LDL levels in the LMWH+INS and DFPP groups showed similar trends, with significant decreases at 2 day after admission [(5.41±3.24) mmol/L vs (2.96±1.47) mmol/L, (4.99±3.51) mmol/L vs (2.47±1.53) mmol/L]. The differences mentioned above are all statistically significant (all P value <0.001). No significant changes were observed in HDL levels in either LMWH+INS and DFPP groups at 2-5 days after admission. After matching, the DFPP group had a significantly longer time of resuming feeding [3(2, 3) days vs 4(3, 6) days] and higher hospital cost [12113.87 (9055.31, 14401.84) yuan vs 28025.34 (25388.11, 36335.48) yuan] compared with the LMWH+INS group, with statistically significant differences. Conclusions:DFPP could reduce TG and TC levels more rapidly and effectively than LMWH combined with INS, but does not show an advantage in improving clinical outcomes and reducing hospitalization costs.

Objective:To investigate the impact of different treatment sequences of immunotherapy combined with chemoradiotherapy (CRT) as the first-line therapy on the prognosis of patients with stage III non-small cell lung cancer (NSCLC).Methods:Clinical data of 112 patients with stage III NSCLC treated at the Fourth Hospital of Hebei Medical University from January 2019 to December 2021 were retrospectively collected, with follow-up continued until December 31, 2023. According to the sequence of CRT and immune checkpoint inhibitors (ICIs) therapy, patients were divided into 3 groups: ICIs simultaneous with CRT (sICR, n=20), chemotherapy combined with ICIs followed by CRT (CI-CR, n=53), and CRT followed by consolidative ICIs (CR-I, n=39). Analyses were performed before and after propensity score matching (PSM). Survival outcomes were assessed using the Kaplan-Meier method and compared by log-rank tests, and prognostic factors were identified through multivariate Cox regression analysis. Results:The median overall survival (OS) and progression-free survival (PFS) for the entire cohort were 30.1 months (95% CI: 21.4-38.9) and 12.8 months (95% CI: 9.14-16.1), respectively. Before PSM: No significant differences were observed in OS and PFS among the 3 groups ( χ2=0.18, 1.05; P=0.669, 0.305). However, OS in the sICR and CR-I groups was significantly better than that in the CI-CR group ( χ2=4.43, 6.11; P=0.035, 0.013). After PSM: Each group included 17 patients. There were no significant differences in OS or PFS among the 3 groups ( χ2=2.50, 2.74; P=0.287, 0.254), and pairwise comparisons also showed no significant differences. Multivariate Cox regression analysis revealed that clinical stage ( HR=3.392, 95% CI: 1.215-9.470, P=0.020), number of immunotherapy cycles ( HR=0.312, 95% CI: 0.100-0.972, P=0.044), and treatment response ( HR=6.566, 95% CI: 1.705-25.284, P=0.006) were independent prognostic factors for OS. After PSM, the numbers of patients with grade ≥2 treatment-related adverse events were 13 in the sICR group, 10 in the CI-CR group, and 9 in the CR-I group, with no significant differences among them ( χ2=2.181, P=0.336). Conclusions:First-line immunotherapy combined with chemoradiotherapy showed favorable clinical efficacy in locally advanced NSCLC compared to other studies, but the treatment sequence did not significantly affect prognosis. It is recommended that immunotherapy be administered for at least four cycles.

Objective:To analyze the clinical characteristics and outcomes of Haemophilus influenzae (Hi) meningitis in children. Methods:This is a retrospective case series study. This study included 34 Hi meningitis patients who admitted to Beijing Children′s Hospital, Capital Medical University, from January 1, 2010, to December 31, 2023. Data on clinical presentations, laboratory tests, hearing assessment and outcomes at discharge were collected. Patients were divided into 2 groups according to the outcome at discharge: favorable outcome group and unfavorable outcome group. Mann-Whitney U test and Fisher exact test was used to estimate the risk factors for an unfavorable outcome at discharge. Results:Thirty-four patients were enrolled. There were 16 males and 18 females. The age at onset ranged from 3 months to 12 years. Fever (34 patients (100%)), convulsions (17 patients (50%)), and coma (21 patients (62%)) were the common clinical presentations. Twenty-four patients (71%) developed complications. There were 15 patients (44%) needed treatment in the intensive care unit, 5 patients (15%) received intubation, and 4 patients (12%) had developed shock. The favorable outcome group included 23 patients, and the unfavorable outcome group included 11 patients. Female, patients with limb movement disability, dystonia, ventriculomegaly or hydrocephalus, and a concentration of glucose in the initial cerebrospinal fluid lower than 1 mmol/L were risk factors of unfavorable outcome at discharge (all P<0.05). Among the 23 patients (68%) in favorable outcomes group, 13 patients (57%) had data available on their long-term follow-up results, including 12 patients with favorable long-term outcomes and 1 patient with unfavorable long-term outcome. Among the 11 patients (32%) in unfavorable outcomegroup, 1 patient died, the other 10 patients (91%) had data available on their long-term outcomes. Eight patients had unfavorable long-term outcomes and 2 patients with favorable long-term outcomes. Patients who had unfavorable outcomes at discharge were at a greater risk of experiencing unfavorable long-term outcomes ( P=0.001). Conclusions:It is common for patients with Hi meningitis to have intracranial complications or develop into critical conditions. Patients who have limb movement disability, dystonia, ventriculomegaly or hydrocephalus, and who exhibit a concentration of glucose in the initial cerebrospinal fluid lower than 1 mmol/L tend to have unfavorable outcomes; they need to be assessed for sequelae.
