Objective To explore the predictive value of systolic pulmonary artery pressure (SPAP) on autonomic nerve excitation in patients with valvular disease, so as to provide reference for the formulation of clinical intervention plans. Methods The clinical data of patients with valvular disease who received surgical treatment in the General Hospital of Northern Theater Command from August 28, 2020 to February 3, 2021 were prospectively collected. According to the standard deviation of normal-to-normal R-R intervals (SDNN) of the heart rate variability (HRV) of the long-range dynamic electrocardiogram (ECG) 7 days before the operation, the patients were divided into three groups: a sympathetic dominant (SE) group (SDNN≤50 ms), a balance group (50 ms

Antrodia cinnamomea is extensively used as a traditional medicine to prevention and treatment of liver cancer. However, its comprehensive chemical fingerprint is uncertain, and the mechanisms, especially the potential therapeutic target for anti-hepatocellular carcinoma (HCC) are still unclear. Using UPLC‒Q-TOF/MS, 139 chemical components were identified in A. cinnamomea dropping pills (ACDPs). Based on these chemical components, network pharmacology demonstrated that the targets of active components were significantly enriched in the pathways in cancer, which were closely related with cell proliferation regulation. Next, HCC data was downloaded from Gene Expression Omnibus database (GEO). The Cancer Genome Atlas (TCGA) and DisGeNET were analyzed by bioinformatics, and 79 biomarkers were obtained. Furtherly, nine targets of ACDP active components were revealed, and they were significantly enriched in PI3K/AKT and cell cycle signaling pathways. The affinity between these targets and their corresponding active ingredients was predicted by molecular docking. Finally, in vivo and in vitro experiments showed that ACDPs could reduce the activity of PI3K/AKT signaling pathway and downregulate the expression of cell cycle-related proteins, contributing to the decreased growth of liver cancer. Altogether, PI3K/AKT-cell cycle appears as the significant central node in anti-liver cancer of A. Cinnamomea.

Objective:To evaluate the long-term results of combined ganglion plexus ablation(GPA) during radiofrequency ablation(RF) with long-standing persistent atrial fibrillation(LSP-AF).Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent valve operations concomitant RF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events. Propensity score matching conducted by RF and RF+ GPA resulted in 102 patients per group.Results:Independent predictors for rhythm success at 1 year were combined GPA( OR=0.205, P=0.005), smaller left atrium size( OR=1.091, P=0.000); at 5-year and 8-year were a shorter history of AF( OR=1.069, P=0.023; OR=1.066, P=0.030), and smaller left atrium size( OR=1.091, P=0.000; OR=1.086, P=0.000). After matching, RF+ GPA group had significantly higher sinus rhythm(SR) without antiarrhythmic drugs(AADs) at 6 months(91.3% vs. 79.8%, P=0.026), 1-year(90.2% vs. 78.5%, P=0.028), but there were no difference between the two groups at 5-year(64.8% vs. 64.4%, P=0.956), and 8-year(53.3% vs. 50.6%, P=0.711). During the 6 postoperative months, fewer patients in the RF+ GPA group underwent follow-up cardioversions(2.0% vs. 8.8%, P=0.030). Actuarial survival curves did not differ significantly between the 2 groups( HR=1.327, 95% CI 0.4633-3.802, P=0.598). Conclusion:The combination of GPA can be effective at the early postoperative stage for SR restoration in Maze Ⅳ procedures for the treatment of LSP-AF in heart valve surgeries, particularly for lower AADs use and lower cardioversions. However, this effect will gradually diminish after one year.

Objective:To evaluate the long-term results of bipolar radiofrequency(BRF) ablation in restoring sinus rhythm in patients with permanent atrial fibrillation(AF) undergoing surgery for cardiac surgery.Methods:This retrospective study sample consisted of 268 patients with LSP-AF underwent cardiac operations concomitant BRF maze Ⅳ procedure. Data were collected prospectively on perioperative outcomes, rhythm status, survival, and clinical events.Results:15 patients died in the early postoperative period, perioperative mortality rate was 5.5%. The rate of stable sinus rhythm(sSR)was 86.6%, 75.4%, 67.7%, 57.8% in 1, 2, 5, 8 years after operation. Multivariate analysis proved the size of the left atrium( HR=1.073, P<0.001) and duration of AF( HR=1.070, P=0.025) to be an independent predictor of the radiofrequency ablation outcome. Conclusion:Bipolar radiofrequency maze procedure can effectively eliminate AF, maintain long-term of sinus rhythm. Bipolar radiofrequency maze procedure is a safe, easy and effective surgical option for the treatment of AF, with satisfactory long-term results, is worthy of promotion.

Objective:To investigate the method and clinical effect of ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm.Methods:From January 2017 to December 2019, 71 patients in Gongren Hospital with femoral pseudoaneurysm were treated by ultrasound-guided thrombin injection. There were 55 cases of fistula type and 16 cases of fissure type. The maximum diameter of the cavity and the neck of pseudoaneurysm were measured and recorded. Two groups of patients were injected thrombin under ultrasound guidance (according to the shape of the pseudoaneurysm neck, different injection methods were used). The treatments for the first time and first recurrence of the two groups were treated with the corresponding conventional injection method. For the second fracture type of the second recurrence of the patients, the method of cross injection and gradual advance to the pseudoaneurysm neck was used for the third time, and the compression time was extended after the blood flow in the cavity disappeared. Ultrasound was performed at 24 hours and 1 week after operation to observe the blood flow and thrombosis.Results:In 55 patients with pseudoaneurysm of fistula type, 54 patients were treated successfully after once injected, pseudoaneurysm recurred in 1 patient relapsed by ultrasound 24 hours after operation, and the second injection was successful. In 16 patients with pseudoaneurysm of fissure type, 10 patients were successfully treated after once injection, 6 patients recurred 24 hours after operation, 4 patients were successfully treated after the second injection, and 2 patients after the third injection. There was no correlation between the recurrence of fistula pseudoaneurysm and the diameter of the pseudoaneurysm neck( r s=0.103, P=0.455), while the recurrence of fissure pseudoaneurysm was closely related to the diameter of the pseudoaneurysm neck( r s=0.870, P<0.001). Finally, all the patients achieved satisfactory curative effect, and the cure rate was 100%. Conclusions:Ultrasound-guided thrombin injection in the treatment of femoral pseudoaneurysm has a significant clinical effect. However it is necessary to determine the shape of the pseudoaneurysm neck and measure the diameter of the pseudoaneurysm neck before operation, so as to adopt a reasonable and effective injection method, to improve the success rate of the first treatment and reduce the recurrence.

Objective    To analyze factors affecting the recovery of postoperative left ventricular function in patients with valvular disease combined with heart failure with reduced ejection fraction [HFrEF, left ventricular ejection fraction (LVEF)<40%]. Methods    The clinical data of 98 patients with valvular disease combined with HFrEF who underwent surgeries in our hospital from January 2011 to June 2018 were retrospectively analyzed, including 75 males and 23 females aged 9-78 (55.3±11.9) years. Results    A total of 15 patients were dead after the operation, including 4 deaths within 3 months and 11 mid-long-term deaths after the operation. Ninety-one patients were followed up for more than 6 months (10 months to 8.6 years). The postoperative cardiac function (NYHA) of 91 patients was classⅠ-Ⅱ, the LVEF of 18 (19.8%) patients increased more than 10%, that of 47 (51.6%) patients maintained at the preoperative level, and that of 26 (28.6%) patients decreased. Postoperative LVEF was more prone to recover in HFrEF patients with sinus rhythm before operation (P=0.038), valvular disease mainly in aortic valve (P=0.026), obvious reduction of left ventricular end diastolic diameter in early postoperative period (P=0.017), and higher systolic pulmonary artery pressure (SPAP) before operation (P=0.018). The risk factors for postoperative LVEF deterioration included large left atrium before operation (P=0.014), smaller left ventricle end systolic diameter before operation (P=0.003), and fast heart rate after operation (P=0.019). Conclusion    Mitral valve prolapse patients with obviously increased left ventricular diameter should receive operation as soon as possible. HFrEF patients with aortic valve disease should receive operation positively. The operation efficacy is satisfactory in the HFrEF patients with high SPAP.

OBJECTIVE: To investigate the expression profile of long non-coding RNAs (lncRNA) and identify potential lncRNA-related competing endogenous RNAs (ceRNA) in placenta accrete spectrum disorders (PAS). METHODS: Five tissue specimens of placental implantation and 5 adjacent normal placental tissues were collected from cesarean section deliveries complicated by PAS in our hospital between December, 2017 and June, 2018. Human microarrays were used to identify the lncRNAs that were differentially expressed in PAS, and 5 of the identified lncRNAs were further validated using qRT-PCR. GO and KEGG pathway analyses were performed to indentify the most significant enrichment functions. A ceRNA network was constructed based on ENST00000511361 (RP5-875H18.4), NR_027457 (LINC00221) and NR_126415 (FOXP4-AS1) to pinpoint the potential lncRNAs-related ceRNA. RESULTS: A total of 329 lncRNAs and 179 mRNAs were identified to have differential expression in PAS. The results of qRT-PCR were consistent with the human microarrays results. Transforming growth factor-β (TGF-β) signaling pathway was the most significantly enriched pathway. The constructed ceRNA network suggested that RP5-875H18.4--miRNA-218--SLIT2 had a potential ceRNA regulatory mechanism in PAS. CONCLUSIONS The differentially expressed lncRNAs are involved in the occurrence and progression of PAS possibly by regulating the TGF-β signaling pathway. The ceRNA network of RP5-875H18.4--miRNA-218--SLIT2 may play a role in the occurrence of PAS.

To evaluate the long term cardiopulmonary function after Fontan operation. Methods 10 patients who received Fontan operation were followed for(26 ±4) years in our hospital. 7 males and 3 females,(30. 7 ± 13. 2) years old(20 -60 years). All patients were diagnosed by echocardiography, CTA, 24 h ECG, cardiac catheterization, pulmonary angiography, radionuclide pulmonary blood perfusion and cardiopulmonary exercise test. Results Echocardiography shows: LVEF(0. 49 ± 0. 04), more than moderate atrioventricular valve regurgitation in 7 cases. CTA shows: there was no anastomotic stenosis, arteriovenous fistula in 4 cases. 24 h ECG shows: sinus rhythm in 7 cases, frequent paroxysmal atrial tachycardia in 1 case, atrial flutter in one and atrial fibrillation in one. Cardiac catheterization and pulmonary angiography show: the average pulmonary artery pressure(17. 8 ±2. 0)mmHg, average pulmonary resistance(4. 17 ±0. 56) woods. Radionuclide pulmonary blood perfusion shows: pulmonary blood of upper lung was reduced significantly with unbalanced distribution. Cardiopulmonary exercise test shows: both of lung ventilation function and heart reserve function decreased moderately or severely. Protein losing enteropathy was found in 1 case. Conclusion The decrease of cardiopulmonary function is found after Fontan operation during the long-term follow up for 20 years, especially for cardiac function. More attention should be paid to the early postoperative atrioventricular valve regurgitation. Unbalanced distribution of pulmonary blood is Found in long term. The incidence of arrhythmia after extra conduit Fontan operation is lower than other methods.

Objective To evaluate the effect of left atrial enlargement on atrial myocardial fibrosis degree and levels of the angiotensinⅡ (AngⅡ)/Rac GTPase activating protein 1 (Rac1)/signal transducersand activators of transcription 3 (STAT3) signaling pathways expressing in patients with persistent atrial fibrillation and rheumatic heart disease (RHD). Methods From March to December 2011, 30 patients with RHD who underwent prosthetic valve replacement in our hospital were enrolled, including 16 males and 14 females, aged 42-70 (56.9±6.8) years. Twenty RHD patients with persistent atrial fibrillation as a research group and ten RHD patients with sinus rhythm as a control group (group A) underwent transthoracic echocardiography and right atrial appendage (RAA) tissue samples were obtained from these patients during mitral/aortic valve replacement operation. The research group according to left atrial diameter (LAD) was divided into two groups, ten patients in each group: a group B with LAD of 50–65 mm and a group C with LAD of LAD>65 mm. For each sample, histological examination was performed by hematoxylin-eosin and Masson’s trichrome staining. Light-microscopic pictures of atrial tissues samples were stained and tissue fibrosis degree in each group was analyzed. AngⅡ concentration was measured by enzyme linked immunosorbent assay. Rac1 and STAT3 were measured by western blotting. Results LAD was significantly greater in AF patients with RHD than in the control group. Hematoxylin-eosin staining demonstrated highly organized arrangement of atrial muscles in the control group and significant derangement in both group B and group C with reduced cell density and increased cell size. Moreover, Masson’s trichrome staining showed that atrial myocytes were surrounded by large trunks of collagen fibers in both group B and group C, but not in the group A. There was a positive correlation between atrial tissue fibrosis and LAD. AngⅡ content was positively correlated with LAD. Similarly, Rac1 and STAT3 protein levels were found considerably higher in the group C and group B than in the group A with excellent correlation to LAD. Conclusion In patients with RHD complicated with persistent atrial fibrillation, the degree of atrial fibrosis and the expression level of AngⅡ/Rac1/STAT3 signaling pathways significantly increase with the left atrialenlargement.
