Gastroparesis after combined heart and lung transplantation.

GOALS: To determine the prevalence, severity, and outcome of gastroparesis after heart and lung transplantation (HLT). STUDY: Ten patients (five women; age range, 27-57 years) underwent HLT at Temple University Hospital from 1996 to 1999. The charts of these patients were reviewed, including results from gastric emptying scans and upper endoscopies. Symptoms were assessed with a standardized questionnaire. RESULTS: The indications for HLT included pulmonary hypertension in six patients, Eisenmenger syndrome in two, and dilated cardiomyopathy and congenital heart disease in two. Four patients died before the start of this clinical analysis. The six surviving patients constituted our study population. The patients' posttransplantation follow-up period ranged from 1.4 to 4.4 years (average, 2.6 years). Five patients (83%) were symptomatic with nausea, vomiting, and postprandial abdominal distension. Solid phase gastric emptying was delayed in all five patients with mean gastric retention of 93% at 2 hours (normal <50%). Patients generally did not respond to prokinetic agents. Four patients required pyloroplasty with J tube placement for symptom control, nutrition, and delivery of immunosuppressive medication. CONCLUSIONS: There is a high prevalence of symptomatic gastroparesis in patients after HLT. The gastroparesis is severe and often resistant to prokinetic agents.

地榆鞣质提取物对TGF-β1诱导人肾小管上皮细胞增殖的影响

摘 要 目的： 通过观察地榆鞣质提取物（STE）对生长转化因子（TGF-β₁）诱导人肾小管上皮细胞（HK-2）增殖的影响,探讨地榆在防治肾间质纤维化方面的作用。方法: 将HK-2细胞用含10%胎牛血清的DMEM高糖培养基培养,实验分为5组：空白对照组、TGF-β₁组（5 ng· mL^-1 TGF-β₁）、干预1组（5 ng· mL^-1 TGF-β₁+12.5 μg·mL^-1 STE）、干预2组（5 ng· mL^-1 TGF-β₁+25μg·mL^-1 STE）、干预3组（5 ng·mL^-1 TGF-β₁+50μg·mL^-1 STE）,孵育24 h。在倒置显微镜下观察各组细胞形态的改变,并通过CCK8法测定地榆鞣质对细胞增殖的影响。结果: TGF-β₁ 5 ng·mL^-1能显著诱导人肾小管上皮细胞增殖,并促进其细胞形态向纤维化转变,相比于空白对照组具有显著差异（P<0.05）;但与地榆鞣质提取物（STE）共同作用后,其促进细胞增殖的作用受到一定抑制（P<0.05）,细胞形态也趋于正常,且呈剂量依赖性。结论:地榆鞣质提取物能抑制HK-2细胞的增殖,在一定程度上具有防止肾间质纤维化的作用。     

Effect of electroacupuncture treatment on functional constipation in adults: A protocol for systematic review

Background:Electroacupuncture has been widely used to treat functional constipation. But its efficiency has not been scientifically and methodically evaluated. The objective of this study is to evaluate the efficiency and safety of the electroacupuncture treatment for functional constipation in adults.Methods:This protocol of systematic review will be conducted in accordance with the Preferred Reporting Items for Systematic Review and Meta-analysis Protocols (PRISMA-P). We will conduct the literature searching in the following electronic databases: the Cochrane Library, MEDLINE, EMBASE, Web of Science, Springer, the Chinese Science Citation Database (CSCD), China National Knowledge Infrastructure (CNKI), the Chinese Biomedical Literature Database (CBM), Wanfang, and the Chinese Scientific Journal Database (VIP). The time limit for retrieving studies is from establishment to July 2020 for each database. All published randomized controlled trials (RTCs) related to this review will be included. Review Manager (V.5.3.5) will be implemented for the assessment of bias risk and data analyses. The selection of the studies, data abstraction, and validations will be performed independently by 2 researchers.Results:This review will assess the clinical efficacy and safety, as well as the acupoints characteristics of electroacupuncture on functional constipation (FC) in adults.Conclusion:This review will summarize the current evidence of electroacupuncture on FC outcomes and provide guidance for clinicians and patients to select electroacupuncture for FC in adults.Trail registration number:This protocol of systematic review has been registered on PROSPERO website (No. CRD42019146715).     

A novel LMNA indel mutation identified in a family with atrioventricular block and atrial fibrillation

It is well known that many genetic factors are involved in the occurrence and progression of atrioventricular block (AV block) and atrial fibrillation (AF). However, the genetic variants discovered so far have only explained parts of these processes. More genes and variants remain to be identified. In the present study, a three-generation family with an autosomal dominant form of AV block and AF was enrolled. Whole exome sequencing was conducted in three affected and one unaffected family member. A total of 64 nonsynonymous variants was shared by three affected individuals and not present in the unaffected individual. By selection of variants absent in the known databases and were predicted to be deleterious, 4 novel variants were identified. Only one novel frameshift insertion in the LMNA gene (c.825_826insCAGG) was identified in another affected family member and not detected in other non-affected family members and the 100 controls. Our finding expanded the spectrum of variants associated with AV block and AF, and was valuable in the genetic diagnosis of AV block and AF.     

High expression of guanine nucleotide-binding protein-like-3-like is associated with poor prognosis in esophageal cancer

Guanine nucleotide-binding protein-like-3-like (GNL3L) is required for processing ribosomal pre-rRNA and cell proliferation and is upregulated in many types of cancer. This study is aimed to investigate the clinical significance of GNL3L in esophageal cancer. The mRNA and protein expression levels of GNL3L were determined by using quantitative real-time polymerase chain reaction and immunohistochemistry, respectively. GNL3L was localized in both cytoplasm and nucleus. The expression levels of GNL3L in esophageal cancer tissues were significantly higher than those in adjacent nonmalignant tissues. High GNL3L expression was associated with pathologic type and poor differentiation. Patients with high GNL3L expression had shorter overall survival (OS) than those with low GNL3L expression. Multivariate Cox regression analysis revealed that GNL3L expression was an independently predictive factor for the OS of patient with esophageal cancer. The Gene Expression Profiling Interactive Analysis (GEPIA) databases also showed that GNL3L was upregulated in esophageal cancer, which was closely associated with an unfavorable prognosis of patients with esophageal cancer. Taken together, our findings suggest that GNL3L is upregulated in esophageal cancer, which is linked to the progression of the disease. As a result, GNL3L could be used as a biomarker for esophageal cancer.
