Incarcerated umbilical hernia in a patient with cirrhotic ascites in combination with chronic lymphocytic leukemia: a case report.

Umbilical hernia is a common type of extra-abdominal hernia in adults. However, chronic granulocytic leukemia in combination with cirrhotic ascites and renal insufficiency is less common. The patient reported here had both indications and contraindications for emergency surgery; therefore, the treatment options were subject to debate. We report the case of a man in his 60s who had a strangulated umbilical hernia, with overlying purple-colored infected and necrotic skin. The area was painful, but his bowel movements were normal. Patients underwent comprehensive conservative management, and remote follow-ups via telephone and video conferencing for a period of 60 days, during which the incarcerated contents of the hernia eventually retracted and his pain was relieved, such that there were no longer indications for emergency surgery. In addition, his skin infection disappeared and his quality of life improved, and therefore the treatment outcomes were good. Thus, we provide evidence that not all incarcerated umbilical hernias require emergency surgery, but may respond well to conservative treatment when the contents do not include intestinal loops or other critical organs.

Giant recurrent left inguinal hernia with femoral nerve injury: a report of a rare case.

BACKGROUND: Giant inguinal hernia(GIH), a rare disease, has brought great challenges to surgeons. GIH is defined as an inguinal hernia that extends below the midpoint of the inner thigh in standing position. However, a giant recurrent inguinal hernia resulting from previous operations that destroy the anatomical structure of the inguinal region is extremely rare. Nerve injury, a complication following inguinal hernia repair, is mostly found in ilioinguinal nerve and iliohypogastric nerve, which often presents as numbness and acute or chronic pain, while postoperative muscular dysfunction results from femoral nerve injury is rare. CASE PRESENTATION: A 77-years-old woman presented with a complaint of a reducible mass in the left inguinal of duration 1 year. The patient had three previous inguinal hernia repairs. Physical examination and auxiliary examination indicated a giant inguinal hernia with femoral nerve injury. After preoperative evaluation and preparation, a transabdominal partial extraperitoneal(TAPE) repair have performed. Finally, the patient recovered and was discharged. CONCLUSIONS: In conclusion, we reported a rare case of a giant recurrent inguinal hernia with femoral nerve injury and made a successful treatment for the patient via transabdominal partial extraperitoneal(TAPE) repair.

Identify potential clinical significance of long noncoding RNA forkhead box P4 antisense RNA 1 in patients with early stage pancreatic ductal adenocarcinoma.

Previous studies have shown that forkhead box P4 antisense RNA 1 (FOXP4-AS1) is dysregulated in tumor tissues and can serve as a prognostic indicator for multiple cancers. However, the clinical significance of FOXP4-AS1 in pancreatic ductal adenocarcinoma (PDAC) remains unclear. The goal of this study is to recognize the possible clinical significance of long noncoding RNA FOXP4-AS1 in patients with early stage PDAC. A total of 112 patients from The Cancer Genome Atlas (TCGA) PDAC cohort, receiving RNA sequencing, were involved in the study. Survival analysis, functional mechanism, and potential small molecule drugs of target therapy of FOXP4-AS1 were performed in this study. Survival analysis in TCGA PDAC cohort suggested that patients with high FOXP4-AS1 expression had significantly augmented possibility of death than in PDAC patients with lower FOXP4-AS1 expression (adjusted P = .008; adjusted HR = 2.143, 95% CI = 1.221-3.760). In this study, a genome-wide RNA sequencing dataset was used to identify 927 genes co-expressing with FOXP4-AS1 in PDAC tumor tissues. A total of 676 differentially expressed genes were identified between different FOXP4-AS1 expression groups. Functional enrichment analysis of these genes and gene set enrichment analysis for PDAC genome-wide RNA sequencing dataset was done. We have found that FOXP4-AS1 may function in PDAC by participating in biological processes and pathways including oxidative phosphorylation, tricarboxylic acid cycle, classical tumor-related pathways such as NF-kappaB as well as Janus kinase/signal transducers in addition to activators of transcription, cell proliferation, and adhesion. In addition, we also screened two potential targeted therapeutic small molecule drugs (dimenhydrinate and metanephrine) for FOXP4-AS1 in PDAC. In conclusion, our present study demonstrated that higher expression of FOXP4-AS1 in PDAC tumor tissues were related with an inferior medical outcome. Through multiple genome-wide approaches, we identified the potential molecular mechanisms of FOXP4-AS1 in PDAC and two targeted therapeutic drugs for it.

Acoustic radiation force impulse elastography for efficacy evaluation after hepatocellular carcinoma radiofrequency ablation: a comparative study with contrast-enhanced ultrasound.

AIM: To explore acoustic radiation force impulse (ARFI) elastography in assessing residual tumors of hepatocellular carcinoma (HCC) after radiofrequency ablation (RFA). MATERIALS AND METHODS: There were 83 HCC lesions among 72 patients. All patients were examined with ARFI, contrast enhanced ultrasound (CEUS), and CT or MRI. Tumor brightness on virtual touch tissue imaging (VTI) and shear wave velocity (SWV) were assessed before and approximately one month after RFA. RESULTS: There were 14 residual tumors after RFA. VTI showed that all the tumors were darker after RFA. VTI was not able to distinguish the ablated lesions and the residual tumors. 13 residual tumor lesions were detected by CEUS. All completely ablated nodules had SWV demonstration of x.xx., while with those residual nodules, 6 tumors had x.xx measurement and 8 tumors had measurable SWV. nine lesions with residual tumors occurred in cirrhosis subjects and 5 lesions with residual tumors occurred in fibrosis subjects; there was no residual tumor in the normal liver subjects. CONCLUSION: VTI technique cannot demonstrate residual tumor post RFA. While SWV measurement of less than x.xx is likely associated with residual tumors, measurement of less than x.xx cannot exclude residual tumors. Liver cirrhosis is associated with decreased chance of a complete ablation.

Knockdown of GPC3 inhibits the proliferation of Huh7 hepatocellular carcinoma cells through down-regulation of YAP.

Glypican-3 (GPC3), a membrane-associated heparan sulfate proteoglycan, is frequently upregulated in hepatocellular carcinoma (HCC). Yes-associated protein (YAP) is also found over-expressed in HCC and has been identified as a key effector molecule in Hippo pathway, which could control the organ size in animals through the regulation of cell proliferation and apoptosis and plays an important role in the development of malignant tumors. Studies have reported that GPC3 and YAP might collaborate to regulate the development of HCC. To elucidate the role of GPC3 in the development of HCC and its relationship with YAP, siRNA technique was employed to knock down GPC3 in Huh7 HCC cells. Moreover, recombinant human YAP-1 was used to examine the effects of GPC3 on Huh7 cells. The results of flow cytometric analysis and Annexin-V-FLUOS apoptosis assay showed that knockdown of GPC3-induced apoptosis in Huh7 cells, resulting in inhibition of cell proliferation as examined by EdU incorporation assay, migration, and invasion. GPC3 knockdown also suppressed the expression of YAP in mRNA and protein levels, as examined by fluorescence quantitative PCR and Western blot analysis. Moreover, addition of recombinant human YAP-1 effectively rescued the cells from apoptosis triggered by GPC3 knockdown. Taken together, our findings suggest that GPC3 regulates HCC cell proliferation with the involvement of Hippo pathway.
