[Budd-Chiari syndrome with hepatopulmonary syndrome: a case report and literature review].

Objective: To summarize the clinical features and prognosis of Budd-Chiari syndrome with hepatopulmonary syndrome (HPS) in children. Methods: The clinical data of a child who had Budd-Chiari syndrome with HPS treated at the Department of Pediatrics of the First Affiliated Hospital of Zhengzhou University in December 2016 was analyzed retrospectively. Taking "Budd-Chiari syndrome" and "hepatopulmonary syndrome" in Chinese or English as the keywords, literature was searched at CNKI, Wanfang, China Biomedical Literature Database and PubMed up to July 2023. Combined with this case, the clinical characteristics, diagnosis, treatment and prognosis of Budd-Chiari syndrome with HPS in children under the age of 18 were summarized. Results: A 13-year-old boy, presented with cyanosis and chest tightness after activities for 6 months, and yellow staining of the skin for 1 week. Physical examination at admission not only found mild yellow staining of the skin and sclera, but also found cyanosis of the lips, periocular skin, and extremities. Laboratory examination showed abnormal liver function with total bilirubin 53 µmol/L, direct bilirubin 14 µmol/L, and indirect bilirubin 39 µmol/L, and abnormal blood gas analysis with the partial pressure of oxygen of 54 mmHg (1 mmHg=0.133 kPa), the partial pressure of carbon dioxide of 31 mmHg, and the alveolar-arterial oxygen gradient of 57 mmHg. Hepatic vein-type Budd-Chiari syndrome, cirrhosis, and portal hypertension were indicated by abdominal CT venography. Contrast-enhanced transthoracic echocardiography (CE-TTE) was positive. After symptomatic and supportive treatment, this patient was discharged and received oxygen therapy outside the hospital. At follow-up until March 2023, there was no significant improvement in hypoxemia, accompanied by limited daily activities. Based on the literature, there were 3 reports in English while none in Chinese, 3 cases were reported. Among a total of 4 children, the chief complaints were dyspnea, cyanosis, or hypoxemia in 3 cases, and unknown in 1 case. There were 2 cases diagnosed with Budd-Chiari syndrome with HPS at the same time due to respiratory symptoms, and 2 cases developed HPS 1.5 years and 8.0 years after the diagnosis of Budd-Chiari syndrome respectively. CE-TTE was positive in 2 cases and pulmonary perfusion imaging was positive in 2 cases. Liver transplantation was performed in 2 cases and their respiratory function recovered well; 1 case received oxygen therapy, with no improvement in hypoxemia; 1 case was waiting for liver transplantation. Conclusions: The onset of Budd-Chiari syndrome with HPS is insidious. The most common clinical manifestations are dyspnea and cyanosis. It can reduce misdiagnosis to confirm intrapulmonary vascular dilatations with CE-TTE at an early stage. Liver transplantation is helpful in improving the prognosis.

Comparison of His-Purkinje Conduction System Pacing with Atrial-Ventricular Node Ablation and Pharmacotherapy in HFpEF Patients with Recurrent Persistent Atrial Fibrillation (HPP-AF study).

BACKGROUND: There is currently no particularly effective strategy for patients with persistent atrial fibrillation accompanying heart failure with preserved ejection fraction (HFpEF), especially with recurrent atrial fibrillation after ablation. In this study, we will evaluate a new treatment strategy for patients with persistent atrial fibrillation who had at least two attempts (≧2 times) of radio-frequency catheter ablation but experienced recurrence, and physiologic conduction was reconstructed after atrioventricular node ablation or drug therapy, to control the patient's ventricular rate to maintain a regular heart rhythm, which is called His-Purkinje conduction system pacing (HPCSP) with atrioventricular node ablation. METHODS AND RESULTS: This investigator-initiated, multicenter prospective randomized controlled trial aimed to recruit 296 randomized HFpEF patients with recurrent atrial fibrillation. All the enrolled patients were randomly assigned to the pacing group or the drug treatment group. The primary endpoint is differences in cardiovascular events and clinical composite endpoints (all-cause mortality) between patients in the HPCSP and drug-treated groups. Secondary endpoints included heart failure hospitalization, exercise capacity assessed by cardiopulmonary exercise tests, quality of life, echocardiogram parameters, 6-minute walk distance, NT-ProBNP, daily patient activity levels, and heart failure management report recorded by the CIED. It is planned to compete recruitment by the end of 2023 and report in 2025. CONCLUSIONS: The study aims to determine whether His-Purkinje conduction system pacing with atrioventricular node ablation can better improve patients' symptoms and quality of life, postpone the progression of heart failure, and reduce the rate of rehospitalization and mortality of patients with heart failure.

TRIM66 promotes malignant progression of hepatocellular carcinoma by inhibiting E-cadherin expression through the EMT pathway.

OBJECTIVE: The aim of this study was to explore the regulatory role of TRIM66 in the development of hepatocellular carcinoma (HCC), and to investigate its underlying mechanism. PATIENTS AND METHODS: A total of 88 pairs of HCC tissues and para-cancerous tissues were surgically resected. The expression of TRIM66 was detected by quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). The correlation between TRIM66 expression and clinic-pathologic characteristics of HCC patients was analyzed. Follow-up data of enrolled HCC patients were collected for survival analysis. Subsequently, TRIM66 expression in HCC cells was determined by qRT-PCR as well. By constructing si-TRIM66, the biological performances of transfected HCC cells were determined using cell counting kit-8 (CCK-8), colony formation and transwell assay. Western blot was performed to measure the protein expressions of relative genes in epithelial-mesenchymal transition (EMT) pathway. Finally, HCC cells were co-transfected with si-TRIM66 and pcDNA-E-cadherin, followed by detection of invasive and migratory abilities. RESULTS: TRIM66 was highly expressed in HCC tissues compared with that of para-cancerous tissues. High expression of TRIM66 was positively correlated with tumor stage, lymph node metastasis and distant metastasis, whereas not correlated with age and sex of HCC patients. Kaplan-Meier curves revealed that a higher expression of TRIM66 was associated with worse prognosis of HCC. Similarly, TRIM66 was also highly expressed in HCC cells. The knockdown of TRIM66 in HCC cells significantly inhibited the proliferative, invasive and migratory abilities of transfected cells. However, TRIM66 down-regulation significantly induced cell apoptosis. Western blot results showed that TRIM66 knockdown in HCC cells markedly downregulated the protein expressions of E-cadherin, N-cadherin, Vimentin and ß-catenin. The inhibited migration and invasion of HCC cells resulted from TRIM66 knockdown were partially reversed by E-cadherin overexpression. CONCLUSIONS: TRIM66 is highly expressed in HCC, which is positively correlated with tumor stage, lymph node metastasis and distant metastasis of HCC patients. In addition, TRIM66 promotes the malignant progression of HCC by inhibiting E-cadherin through the EMT pathway.

Assessment of the effect of the Aquamantys® system on local recurrence after hepatectomy for hepatocellular carcinoma through propensity score matching.

OBJECTIVE: To assess the effect of the intraoperative application of the Aquamantys® system to treat the hepatic resection margin on local and overall recurrence of HCC. METHODS: We retrospectively analyzed 101 patients admitted from November 2016 to June 2018 who underwent hepatectomy using the Aquamantys® as hemostatic device, who were matched with 101 patients (control group) using conventional hemostatic devices through PSM. Univariate and multivariate analyses of recurrence-free survival (RFS) and local recurrence-free survival (LRFS) were performed using the Cox proportional hazard model. RESULTS: There were no significant differences in baseline data and surgical procedures between the two groups. The Aquamantys® group showed less blood loss (P = 0.005) and a lower blood transfusion rate (P = 0.036), while the incidences of postoperative complications of the two groups showed no difference (P = 0.266). OS rates of the Aquamantys® group and the control group were 82.6% and 84.2%, respectively (P = 0. 446), and RFS rates were 65.5% and 58.2%, respectively (P = 0.153), with no significant differences. The Aquamantys® group and the control group had two cases and 11 cases of local recurrence, respectively, with LRFS rates of 98% and 87.9%, respectively, in the follow-up period, corresponding to a significant difference (P = 0.011). Multivariate analysis showed that microvascular invasion (MVI), tumor diameter > 5 cm, and the control group were independent risk factors for LRFS. CONCLUSION: Our results indicate that application of the Aquamantys® system in hepatectomy can reduce local recurrence, but it can neither reduce overall recurrence nor improve OS.

A 4-miRNAs signature predicts survival in glioblastoma multiforme patients.

BACKGROUND: Although O(6)-methylguanine DNA methyltransferase (MGMT) promoter methylation status is an important marker for glioblastoma multiforme (GBM), there is considerable variability in the clinical outcome of patients with similar methylation profles. OBJECTIVE: We examined whether a MicroRNA (miRNA) signature can be identified for predicting clinical outcomes and helping in treatment decisions. METHODS: The differentially expressed miRNAs were evaluated in 6 pairs of short- (⩽ 450 days) and long-term survivors (> 450 days) by using microarray. Real time quantitative PCR (qRT-PCR) was applied to further verify screened miRNAs with a greater number of samples (n= 48). Meanwhile, functional interpretation of miRNA profile was carried out based on miRNA-target databases. In addition, MGMT promoter methylation status was tested by means of pyrosequencing (PSQ) testing. RESULTS: Six miRNAs were upregulated in the long-term survival group (fold change ⩾ 2.0, P< 0.05). The further verification by qRT-PCR indicated that the increase in let-7g-5p, miR-139-5p, miR-17-5p and miR-9-3p level in long-term survivors was statistically significant. Kaplan-Meier survival analysis showed that high expression of a prognostic 4-miRNA signature was significantly associated with good patient survival (p= 0.0012). The signature regulated signaling pathways including Calcium, MAPK, ErbB, mTOR and cell cycle involved in carcinogenesis from glial progenitor cell to primary GBM. CONCLUSIONS: The 4-miRNA signature was identified as an independent prognostic biomarker that identified patients who have a favorable outcome.

[Clinical Investigation on CT guided cryoablation for treating invasive chest wall or pleural tumors].

Objective: To evaluate the feasibility and short-term effect of CT guided cryoablation for malignant chest wall or pleural involvement. Methods: To follow up 22 patients with chest wall or pleural involvement of various malignancies who underwent cryoablation from January 2012 to January 2015 by conducting postoperative 1-, 3- and 6-month enhanced CT, MRI or PET-CT examinations, respectively, evaluate local curative effect, and observe their progression-free survival (PFS), postoperative pain remission and complications after the cryoablation. Results: A total of 22 patients with 27 lesions received 26 times of argon-helium cryoablation. According to the coverage situation of immediate postoperative ice balls on the lesions, they were divided into a complete coverage group (Group A with 18 patients) and a partial coverage group (Group B with 4 patients). 1 month later, 15 patients' tumors were completely ablated, and 3 had residue and thus received the second cryoablation in Group A, while all patients' tumors had residue in Group B. 3 months later, 17 patients' tumors were completely ablated, and 1 had residue and thus received another cryoablation in Group A, while all patients' residual tumors enlarged in different extent in group B. 6 months later, all lesions were ablated in group A while all patients' residual tumors enlarged in group B. For the 22 patients, their preoperative, and postoperative 1-week, 1-month, 3-month, and 6-month VAS scores were 4.95±0.57, 1.45±0.35, 1.45±0.35, 1.64±1.71, and 2.00±2.35, respectively. The differences in the preoperative, postoperative 1-week, and postoperative 1-month scores are significant statistically (P<0.05), and the difference in the postoperative 1-month and 6-month scores is also with statistical significance (P=0.03). For all patients, their post-operative 1-week, 1-month, 3-monte and 6-month pain remission rates are 90.9%(20/22), 90.9%(20/22), 86.4% (19/22)and 81.8%(18/22), respectively. With a median follow-up of 13.5 months, the median PFS is 7 months. The adverse effect after argon-helium cryoablation involved transitory worsened pain (16 cases), pleural effusion (5 cases, including 3 underwent closed drainage), fever (5 cases), and hemoptysis (3 cases). Conclusion: CT guided argon-helium cryoablation is a safe and effective method to treat malignant chest wall or pleural involvement.

Clinical efficacy of gamma knife and surgery treatment of mesial temporal lobe epilepsy and their effects on EF-Tumt and EF-Tsmt expression.

OBJECTIVE: To study the clinical efficacy of gamma knife and surgery treatment of mesial temporal lobe epilepsy (MTLE) and their effects on EF-Tumt and EF-Tsmt expression. PATIENTS AND METHODS: The data of 78 cases of MTLE patients treated in our hospital from April 2011 to March 2013 were retrospectively analyzed. The patients were divided into two groups according to the treatment methods: the surgery group (including 41 cases) and the gamma knife group (including 37 cases). The clinical efficacy, the occurrence and recurrence of complications were evaluated, respectively; meanwhile, the expression of the EF-Tumt protein and EF-Tsmt protein in brain tissue were analyzed. RESULTS: The difference between the efficacy rate of the two groups showed no statistical significance (χ2=0.960, p>0.05). The complication rate of the gamma knife group was significantly lower than that of the control group (χ2=6.430, p<0.05). The recurrence rate of the patients in the gamma knife group was significantly lower than that of the patients in the surgery group (p>0.05). Within the two groups, the positive expression granum of EF-Tsmt protein and EF-Tumt protein of the two groups after treatment were significantly lower than that before treatment (p<0.05). After treatment, the positive expression granum of EF-Tsmt protein of the patients in the gamma knife group was obviously more than that of the patients in the surgery group (p<0.05). The difference between the positive expression granum of EF-Tumt protein of the two groups showed no statistical significance (p>0.05). Before and after treatment within the group, the positive cell of EF-Tsmt protein and EF-Tumt protein of the two groups of patients after treatment were significantly lower than that before treatment (p<0.05). After treatment, the difference between the EF-Tsmt protein positive cell and the EF-Tumt protein positive cell of the two groups of patients showed no statistical significance (p>0.05). CONCLUSIONS: Both surgery and gamma knife could treat MTLE effectively, and the efficacy may be related to the ability to reduce the expression of EF-Tsmt protein and EF-Tumt protein in brain tissue.

Combination of IL-6, IL-10, and MCP-1 with traditional serum tumor markers in lung cancer diagnosis and prognosis.

Early detection and treatment is critically important for lung cancer patients. Inflammatory mediators such as IL-6, IL-10, and MCP-1 participate in lung cancer regulation. CEA, CA125, and ProGRP are commonly used serum tumor markers for lung cancer. In this study, we assessed the sensitivity and specificity of CEA, CA125, and ProGRP when used in combination with IL-6, IL-10, and MCP in lung cancer diagnosis. Serum from three different groups (healthy controls, individuals with high risk for lung cancer, and lung cancer patients) was collected. Electrochemiluminescence was used to detect expressions of CEA, CA125, and ProGRP; ELISA was used to examine serum levels of IL-6, IL-10, and MCP-1. Specificity and sensitivity of single as well as combination markers in lung cancer diagnosis were determined. Results indicated that CEA, CA125, ProGRP, and MCP-1 were significantly up-regulated in lung cancer patients as compared to those in controls and high risk individuals. Higher IL-6 and IL-10 levels were observed in both lung cancer patients and high-risk individuals as compared to those in controls. Highest sensitivity (95.2%) in cancer diagnosis was achieved when all six markers were used. This was followed by a combination of IL-6, IL-10, CEA, CA125, and ProGRP (92.6%). The most sensitive (88.6%). Four-marker combination was composed of IL-6, CEA, CA125, and ProGRP. As the combined usage of CEA, CA125, ProGRP, IL-6, IL-10, and MCP-1 significantly improved sensitivity of lung cancer detection; this biomarker arrangement may be beneficial for early diagnosis, treatment, and prognosis of lung cancer.

[The diagnosis and treatment of primary thyroid lymphoma].

Primary thyroid lymphoma (PTL) refers to the malignant tumor of primary lymphoid tissue in the thyroid, accounting for approximately 5% of all thyroid malignancies and less than 3% of all extranodal lymphomas. PTL usually develops in females more than 50 years old. Most of PTL cases are non-Hodgkin's lymphomas. The major pathological subtypes are mucosa-associated lymphoid tissue lymphoma and diffuse large B-cell lymphoma. Treatment options for individual pathological subtypes are also different, so pathological diagnosis is very important. The main treatment options include surgical treatment, radiotherapy, chemotherapy, targeted therapy and combined therapy. The main aims of surgical treatment are to obtain a determined diagnosis and to relieve airway pressure, . The prognosis of PTL is generally excellent.
