Neutrophil-lymphocyte Ratio Plus Prognostic Nutritional Index Predicts the Outcomes of Patients with Unresectable Hepatocellular Carcinoma After Transarterial Chemoembolization.

For many malignancies, inflammation-based scores correlate with survival. The neutrophil-to-lymphocyte ratio (NLR) and prognostic nutritional index (PNI) are immunonutritional indices associated with postoperative outcomes in patients with hepatocellular carcinoma (HCC). We evaluated whether a combined preoperative NLR and PNI score was prognostically superior to either index alone in 793 patients with unresectable HCC after transarterial chemoembolization. Patient demographic, clinical, and pathological data were also collected and analysed. A receiver-operating characteristic (ROC) analysis was used to classify patients as follows: NLR-PNI 0 group (NLR ≤ 2.2 and PNI > 46), NLR-PNI 1 group (NLR > 2.2 or PNI ≤ 46) and NLR-PNI 2 group (NLR > 2.2 and PNI ≤ 46). Regarding 1-, 3-, and 5-year survival, the NLR-PNI score had superior discriminative abilities (i.e., higher area under the ROC curve), compared with either the NLR or PNI alone, and patients in the NLR-PNI 0, 1, and 2 groups had median survival times of 33 (95% confidence interval: 22.8-43.2), 14 (10.9-17.1), and 6 (9.9-14.1) months, respectively. In multivariate analyses, the Barcelona Clinic Liver Cancer, total bilirubin, vascular invasion, and NLR-PNI score adversely affected overall survival. In conclusion, the NLR-PNI score can improve the accuracy of prognoses for patients with unresectable HCC.

Overexpression of miR-96 promotes cell proliferation by targeting FOXF2 in prostate cancer.

Prostate cancer (PC) is one of the most common cancers in males. MicroRNAs (miRNAs) are demonstrated to be involved in prostate cancer development and progression. Recently, miR-96 was identified to play a tumor promoting role in several tumors including PC, however, the underlying function of miR-96 in PC still need to be known. In the study, our results demonstrated that miR-96 was higher in prostate cancer tissues compared with adjacent normal tissues. Higher miR-96 was association with higher PSA level, lymph node metastasis, pathologic stage and distant metastasis in prostate cancer patients. Lose-of-function studies showed that down-regulated expression of miR-96 inhibited cell proliferation and cell cycle by regulating down-regulating CyclinA1, CDK2 and CDK4 expression in PC cells. Furthermore, we found that FOXF2 was a target of miR-96 in PC cells and miR-96 promoted cell proliferation by suppressing FOXF2 expression. Thus, these results showed that inhibition of miR-96 may be a target for prostate cancer treatment.

[Two Methods of Internal Iliac Artery Exclusion in Endovascular Aorta Repair: a Middle-long Term Follow-up Study].

OBJECTIVE: To compare the middle and long term results of two internal iliac artery exclusionmethods (with or without coils) in endovascular aorta repair (EVAR). METHODS: Clinical data of patients who underwent EVAR from January 2006 to December 2013 were analyzed retrospectively. The participants were divided into two group: coils were not used in Group A, but were used in Group B. The patients were followed up from June 2006 to June 2014. RESULTS: A total of 137 patients (74 in Group A, 63 in Group B) were included in this study, with a mean age of 71. 6 years. The majority (124) of participants were men. Postoperative 30-day mortality of the participants was 0. 73%. None of the participants developed pelvic and spinal ischemia. Claudication appeared in 9 patients (3 in Group A and 6 in Group B). Ischemia in lower extremity happened in 5 patients (2 in Group A and 3 in Group B). Gluteal sore was reported by 5 patients (1 in Group A and 4 in Group B). One patient from Group B developed gluteal skin necrosis. No statistical difference in ischemia and stent occlusion was found between the two groups (P=0. 301, P=0. 108). However, patients in Group B stayed in hospitals longer (P<0. 001) than those in group A. One patient in Group B developed severe ischemic complication: skin and gluteus necrosis. CONCLUSION: Internal iliac artery exclusions with and without coilsresult in similar middle and long term outcomes measured by ischemic complications.

[Clinical and pathological characteristics and surgical treatment of carotid body tumor with endocrine activity].

OBJECTIVE: To investigate the clinical and pathological characteristics and surgical treatment of carotid body tumor with endocrine activity (CBT). METHODS: Records of seven CBT patients with endocrine activity (Jan, 1991-Aug, 2011) who underwent surgical excision of tumor were retrospectively reviewed. The operations were performed with the careful peroperative preparation on the control of blood pressure, serum potassium and catecholamine. All the tumors were studied with the methods of HE staining, immunohistochemistry of chromogranin A (CgA) and S-100. RESULTS: All the operations were successfully accomplished and the patients recovered quickly. It was confirmed with pathological examination that all the tumors were CBT, coming from paraganglioma. Tumor cells and sertoli cells were found in HE staining, and all were positive of CgA and S-100. All patients were followed up for 12-60 months and no recurrence was found during the follow up. CONCLUSION: CBT with endocrine activity presents with identifiable clinical and pathological characteristics. The recommended treatment is surgical resection, careful perioperative preparation and care is important to avoid the severe complication due to the endocrine activity of tumor.

[The effect of ischemic postconditioning on apoptosis induced by acute hot renal ischemic-reperfusion].

OBJECTIVE: To investigate the effects of ischemic postconditioning(IPo) on cellular apoptosis in acute renal ischemic-reperfusion injury (IRI) in rats. METHODS: Model of acute renal ischemic-reperfusion injury (IRI) was constructed using Wistar rats. Forty healthy male rats were divided into 4 groups randomly,including group C,group IRI, group IPo and group Ado. Rats of group C received right nephronectomy and separation of left renal vessels. Before reperfusion, group IPo was perfused for 10 s, following ischemic reperfusion for another 10 s with 6 cycles. Group Ado was infused with adenosine intravenously 10 min before ischemia. Cellular apoptosis was determined with TUNEL (TdT-mediated dUTP Nick End Labelling), flowcytometry and histopathological staining. RESULTS: Compared with group C, the apoptotic index increased predominatly in group IRI (P<0.05), whereas, apoptosis index decreased obviousely in group IPo, Ado (P<0.05). In addition, the apoptosis index between group IPo and Ado was not statistically different. CONCLUSION: Ischemic postconditioning could decrease cellular apoptosis induced by IRI in rat kidney.
