Left ventricular pseudoaneurysm was a rare and potentially dangerous complication after myocardial infarction. Compared with true aneurysm, left ventricular pseudoaneurysm had a worse prognosis. A 56-year-old male patient was admitted to hospital with "chest pain for 15 years, recurrent gasping and loss of consciousness for 6 years". After admission, echocardiography and cardiac CT were performed to confirm true aneurysm complicated with left ventricular pseudoaneurysm rupture, and aneurysm resection plus coronary artery bypass grafting was performed. Enhanced cardiac CT examination 6 years after surgery showed complete repair of the rupture, and the patient was generally fine.

Objective:To investigate the clinical features, diagnostic methods and treatments of left ventricular apical fibroma.Methods:The clinical manifestations, ECG, imaging features and treatment plans of 2 patients with giant fibroma of left ventricular apex diagnosed in September 2020 and May 2022 were analyzed retrospectively, and the related literature was reviewed.Results:Both patients had slight chest distress and discomfort after activities. The ECG showed T-wave inversion of different degrees, which were misdiagnosed as “myocarditis” and “coronary heart disease” respectively. The cardiac magnetic resonance imaging and echocardiography showed left ventricular apical mass. Coronary artery stenosis was not found in coronary angiography. One patient required conservative treatment, and there was no significant change in clinical symptoms and tumor size in the follow-up for half a year; Another patient underwent cardiac mass removal, and the pathological examination after operation confirmed that it was cardiac fibroma, and there was no recurrence in the follow-up 2 years.Conclusion:Fibroma of left ventricular apex is a rare cardiac tumor, which is easy to be missed and misdiagnosed, and is one of the rare causes of T-wave inversion. Cardiac magnetic resonance imaging, CT and echocardiography are commonly used imaging methods to diagnose cardiac fibroma, and surgical resection is an effective treatment.

BACKGROUND: Evidence on the relations of the American Heart Association's ideal cardiovascular health (ICH) with mortality in Asians is sparse, and the interaction between behavioral and medical metrics remained unclear. We aimed to fill the gaps. METHODS: A total of 198,164 participants without cancer and cardiovascular disease (CVD) were included from the China Kadoorie Biobank study (2004-2018), Dongfeng-Tongji cohort (2008-2018), and Kailuan study (2006-2019). Four behaviors (i.e., smoking, physical activity, diet, body mass index) and three medical factors (i.e., blood pressure, blood glucose, and blood lipid) were classified into poor, intermediate, and ideal levels (0, 1, and 2 points), which constituted 8-point behavioral, 6-point medical, and 14-point ICH scores. Results of Cox regression from three cohorts were pooled using random-effects models of meta-analysis. RESULTS: During about 2 million person-years, 20,176 deaths were recorded. After controlling for demographic characteristics and alcohol drinking, hazard ratios (95% confidence intervals) comparing ICH scores of 10-14 vs. 0-6 were 0.52 (0.41-0.67), 0.44 (0.37-0.53), 0.54 (0.45-0.66), and 0.86 (0.64-1.14) for all-cause, CVD, respiratory, and cancer mortality. A higher behavioral or medical score was independently associated with lower all-cause and CVD mortality among the total population and populations with different levels of behavioral or medical health equally, and no interaction was observed. CONCLUSIONS ICH was associated with lower all-cause, CVD, and respiratory mortality among Chinese adults. Both behavioral and medical health should be improved to prevent premature deaths.

Objective: To investigate the efficacy and safety of cuboid stereotactic aspiration of necrotic brain tissue for treating malignant middle cerebral artery infarction in the elderly patients. Methods: Sixteen elderly patients with malignant middle cerebral artery infarction were selected from June 2017 to January 2019 in our hospital. Patients were followed up for 6 months to evaluate the efficacy of stereotactic aspiration of necrotic brain tissue using the modified Rankin Scale (mRS). Results: The 30-day mortality was 18.75%. Among the 16 elderly patients, 6 (37.5%) had an mRS score of 3 (defined as moderate disability), 6 (37.5%) had an mRS score of 4 (defined as moderate to severe disability), 1 (6.25%) had an mRS score of 5 (defined as severe disability), and 3 (18.75%) had an mRS score of 6. The probability of 6-month favorable outcome, defined as an mRS score of ≤3, was 37.5%, and the 6-month mortality was 18.75%. Conclusions It is a simple, minimally invasive, effective and safe method to treat malignant middle cerebral artery infarction in the elderly patients with cuboid stereotactic aspiration of necrotic brain tissue, which needs to be confirmed by further randomized controlled studies.

Objective To investigate the related factors of nosocomial infection after severe thoracic trauma so as to provide basis and interventions for lowering nosocomial infection rate.Methods A retrospective case series study was conducted in 148 cases of severe thoracic trauma surgically treated from January 2014 to January 2016.There were 98 males and 50 females with an average age of 34.7 years.The abbreviated injury scale (AIS) was ≥ 3 points.The incidence of nosocomial infection was statistically analyzed.The possible factors related to nosocomial infection were analyzed,including age,gender,previous basic diseases,coma,blood transplantation,surgical procedure,operation time,tracheal intubation time,postoperative tracheotomy,and postoperative ICU hospitalization.Results Nosocomial infection occurred in 18 cases,with infection rate of 12.2％.There were 11 cases of pulmonary infection,four urinary tract infection,two incision infection,and one thoracic cavity infection.There were four cases (22％) of Gram-positive bacteria as pathogen,both of which were Staphylococcus aureus.A total of 12 cases (67％) were Gram-negative bacteria,among which four were infected with Klebsiella pneumonia,three with Acinetobacter baumannii,three with Pseudomonas aeruginosa,and two with Escherichia coli.Two cases were infected by fungi.The incidence of infection was correlated with the patients' age (≥ 60 years),previous basic disease,coma,operation methods,operation time (≥3 hours),endotracheal intubation time (≥24 hours),tracheotomy after surgery,and postoperative hospitalization duration in the ICU (P ＜ 0.05),rather than gender and blood transplantation.Conclusions The most common pathogen of nosocomial infection in severe thoracic trauma patients is Gram-negative bacteria.The older age,previous basic diseases,coma,thoracotomy,long operation time,long tracheal intubation time,tracheotomy and long ICU hospital stay are the risk factors for nosocomial infection.More attention should be paid to these risk factors in order to minimize the occurrence of postoperative hospital infection,and to reduce the harm to patients.

Objective Subarachnoid hemorrhage ( SAH) is a devastating disease with high fatality and morbidity and micro-glia/macrophage ( M/M) plays a vital role in SAH brain injury with complicated pathophysiological mechanism .This study was to ob-serve the effect of Nrf2 deficiency on M/M activation and M1 polarization after subarachnoid hemorrhage in mice . Meth ods We col-lected 70 wild-type ( WT) ICR mice and 35 Nrf2-knockout ( KO) mice to establish the SAH model by injecting fresh autologous blood into pre-chiasmatic cistern.WT mice were arranged into four groups: sham operation group, post operative day 1 (POD1) group, POD3 group and POD5 group.Then WT mice and Nrf2 Nrf2-knockout mice were divided into sham operation WT group , sham opera-tion KO group, SAH WT group and SAH KO group.Western blotting (WB) and immunohistochemistry (IHC) were applied to observe the activation and proliferation of M/M after SAH on WT mice .Difference in activation and M 1 polarization were observed by detecting Iba1 expression in WB and CD 16/32 +Iba1 +cells in immunofluorescence between WT and KO mice . Results Gray scale values of Iba1 expression by WB in WT mice are 0.491 ±0.039, 0.657 ± 0.069, 0.930 ±0.046 and 0.926 ±0.046;average optical intensity values of Iba1 expression by IHC in WT mice are 0.412 ±0.122, 0.625 ±0.135, 0.963 ±0.213 and 0.978 ±0.224.The data indica-ted that Iba1 expression increased in SAH KO group in comparison to SAH WT group on 1, 3, 5 day after SAH (P<0.05).Moreover, Nrf2 deficiency promoted the activation and polarization of M /M by increased Iba1 protein expression and CD16/32 +Iba1 +cells after SAH ( P<0.05). Conclusion SAH induces M/M activation and proliferation in mice, and Nrf2 deficiency promotes the activa-tion, proliferation and M1 polarization after SAH .

Objective To investigate the risk factors, clinical and angiographic features of women aged 50 or less with coronary artery disease(CAD). Methods One hundred and seventy-three female CAD patients comifrmed by coronary angiographic aged 50 or less were classiifed as group A, while another 494 non-CAD women aged 50 or less as group B. The differences in CAD risk factors, clinical and angiographic features between the 2 groups were analyzed. Results There were more women with diabetes, positive CAD family history, dyslipidemia or hypertension (especially diastolic hypertension) in group A than in group B. Patient in group A had higher diastolic pressures and serum glucose level than those in group B but both groups had similar body weights, systolic pressures and menopause ages. The serum total cholesterol and triglyceride levels were higher in patients in group A than those in group B while high-density-lipoprotein (HDL) cholesterol and apolipoprotein A levels were lower in group A. The low-density-lipoprotein (LDL) and apolipoprotein B were higher in group A than in group B but without signiifcance. There were more women with positive urine protein in group A than in group B. In group A, more than 50%of patients were with single diseased artery while another 15%with slight coronary artery atherosclerosis or even normal arteries. Most of the lesions were found in left anterior descending artery (LAD) and its branches. Conclusions Risk factors of CAD included diabetes, positive CAD family history, dyslipidemia, hypertension(especially diastolic hypertension) and positive urine protein in women aged 50 or less Menopause alone, without other CAD risk factors, would not lead to CAD. Single vessel disease was more commonly found in this group of patients.

Objective Subarachnoid hemorrhage ( SAH) is a devastating disease with a high mortality.This study was to in-vestigate the effect of Nrf2 on secondary brain injury following SAH and its action mechanism in mice. Methods SAH models were established in wild-type ( WT) and Nrf2 knockout ( KO) ICR male mice by injecting fresh blood drawn from the femoral artery into the pre-chiasmatic cistern.The animals were divided into four groups, WT sham, WT SAH, KO sham, and KO SAH.At 24 hours after modeling, the expression levels of malondialdehyde ( MDA) , GSH/GSSG, TNF-αand IL-1β, the volume of brain water, and content of Evans blue were measured, the activity scores obtained, and cerebral vasospasm of the anterior and middle cerebral arteries ( ACA and MCA) detected. Results At 24 hours, the expressions of MDA, TNF-α, and IL-1βwere (3.299 ±0.335), (1.187 ± 0.436), and (59.330 ±21.787) mg/g in the WT sham group, (4.339 ±0.328), (2.432 ±0.434), and (121.584 ±21.675) mg/g in the WT SAH group, (3.488 ±0.634), (1.170 ±0.312), and (58.497 ±15.608) mg/g in the KO sham group, and (5.335 ±0.499), (3.132 ±0.548), and (171.117 ±50.479) mg/g in the KO SAH group, markedly increased in the SAH groups as compared with the sham controls (P<0.05), while the GSH/GSSG levels were significantly higher in the former two groups than in the latter (0.553 ±0.100 and 0.375 ±0.068 vs 0.714 ±0.091, 0.761 ±0.114, P<0.01).The contents of brain water and Evans blue were (0.784 ±0.005) and (7.055 ±1.046) μg/g in the WT sham group, (0.808 ±0.004) and (7.230 ±1.192) μg/g in the WT SAH group, (0.784 ±0.004) and (9.620 ±1.290) μg/g in the KO sham group, and (0.819 ±0.004) and (11.628 ±1.040)μg/g in the KO SAH group, remarkably increased in the SAH groups in comparison with the sham groups (P<0.05).The apoptosis rate 8.916 and 82.100 ±6.870 vs 70.833 ±8.750 and 51.767 ±13.006), ACA radius/wall thickness value (13.885 ±3.360 and 14.212 ±3.2545 vs 8.024 ±2.780 and 6.861 ±2.702), MCA radius/wall thickness value (18.648 ±2.893 and 19.435 ±2.775 vs 6.337 ±3.993 and 5.107 ±3.805), and activity score (2.733 ±0.450 and 2.767 ±0.430 vs 1.967 ±0.928 and 1.433 ±0.679) (all P<0.01). Conclusion Nrf2 knockout increases oxidative stress and inflammatory reaction following SAH and consequently aggravates secondary brain injury.Nrf2 has a protective effect against SAH-induced brain injury.

Objective To investigate the expression and cellular localization of cyclin-dependent kinase 5 (Cdk5) in cerebral cortex after subarachnoid hemorrhage (SAH) in rats.Methods Fifty-two male Sprague Dawley (SD) rats were randomly divided into either a sham operation group (n =12) or a SAH group (n =40).The latter was randomly redivided into 6,12,24 h,and day 2 and 3 subgroups (n =8 in each group).A rat SAH model was induced by injecting fresh blood into the prechiasmatic cistern.Western blot and immunohistochemistry were used to detect the expression of Cdk5 in rat brain cortex.Double labeling immunofluorescence staining was used to detect the cellular localization of Cdk5 protein in cerebral cortex.Neuronal nuclear antigen labeled neurons,and glial fibrillary acidic protein labeled astrocytes.Results Western blot showed that the expression of Cdk5 protein was up-regulated at 12 hours after SAH (t =3.709,P =0.001),and it reached the peak on day 1 (t =3.475,P=0.002).Immunohistochemistry showed that the proportion of Cdk5 positive cell was also increased gradually after SAH,and the changes of time course were consistent with the results of Western blot,and it reached the peak on day 1 (t =4.320,P =0.000).Double labeling immunofluorescence showed that Cdk5 was mainly expressed in the neuronal cytoplasm in the sham operation group,and Cdk5 shifted to the neuronal nuclei in the SAH group.Cdk5 was mainly colocalized between astrocytes and neurons.Conclusions SAH up-regulates the expression of Cdk5 protein in cerebral cortex.Cdk5 may be involved in early brain injury after SAH.
