Background: The detailed mechanisms of knee osteoarthritis (OA) pain have not been clarified, but involvement of inflammatory cytokines such as tumor necrosis factor-alpha (TNF) has been suggested. The present study aimed to investigate the more detailed neurological involvement of TNF in joint pain using a TNF-knockout mouse OA model. Methods: The right knees of twelve-week-old C57BL/6J wild and TNF-deficient knockout (TNF-ko) mice (n=15, each group) were given a single intra-articular injection of 10 µg monoiodoacetate in 10 mL sterile saline. The left knees were only punctured as the control. Evaluations were performed immediately after the injection (baseline) and at 7, 14, and 28 days after the injection with a subsequent intra-articular injection of neurotracer into both knees. The animals were evaluated for immunofluorescence of the lumbar dorsal root ganglia (DRG) innervating the knee joints. The injected knees were observed macroscopically and mouse pain-related behaviors were scored. Results: Macroscopic observation showed similar knee OA development in both wild and TNF-ko mice. Calcitonin gene-related peptide (CGRP, a neuropeptide identified as a inflammatory pain-related biomarker) was significantly increased in DRG neurons innervating OA-induced knee joints with significantly less CGRP expression in TNF-ko animals. Pain-related behavior scoring showed a significant increase in pain in OA-induced joints, but there was no significant difference in pain observed between the wild and TNF-ko mice. Conclusions: The result of the present study indicates the possible association of TNF-alpha in OA pain but not OA development. 相似文献

Adaptive servo ventilation (ASV) is reported to be effective for the treatment of heart failure. We treated a patient with idiopathic dilated cardiomyopathy using ASV and assessed the effects on hemodynamics, coronary flow, and flow reserve before and after ASV therapy. This case suggests that ASV might decrease myocardial oxygen demand, which was represented by the decreased resting coronary flow velocity (the improvement of coronary flow velocity reserve) on ASV. 相似文献

Purpose
Malnutrition has been considered a risk factor for the development of a surgical site infection (SSI). The aim of this study was to determine the relationship between preoperative nutritional screening scores and the development of SSI after pancreaticoduodenectomy.Methods
We examined 64 patients who had undergone pancreaticoduodenectomy. Their clinical data, nutritional risk index (NRI), and nutritional risk screening 2002 (NRS-2002) score were recorded. SSIs were diagnosed according to the definitions of wound infection established by the Center for Disease Control and Prevention and were confirmed by a microbiological examination. Data were analyzed using the Fisher exact probability method and a multivariate logistic regression analysis.Results
SSIs developed in 21 patients (33 %). Eleven patients had wound infections, and 14 patients had an intra-abdominal abscess. A univariate analysis of perioperative factors revealed that a pancreatic fistula, the NRS-2002, and the NRI were significantly associated with the development of SSI (p < 0.05). The multivariate logistic regression analysis revealed that a pancreatic fistula and the NRI were independent risk factors for SSI. By analyzing the pre- and intra-operative factors after excluding the 11 patients with pancreatic fistulas, the NRI was still an independent risk factor for SSI.Conclusion
The present study showed the NRI to be an independent factor for predicting the risk of SSI after pancreaticoduodenectomy. 相似文献58.

Background
The present study aimed to clarify the clinicopathologic features of long-term disease-fee survival after resection of hepatocellular carcinoma (HCC).Methods
This retrospective study identified 940 patients who underwent curative resection of HCC between 1991 and 2000 at five university hospitals. Seventy-four patients with 10 years of recurrence-free survival were identified and followed up. They were divided into two groups, 60 recurrence-free and 14 with recurrence after a 10-year recurrence-free period.Results
Overall survival rates of recurrence and non-recurrence groups were 68 and 91 % at 16 years, and 34 and 91 % at 20 years (p = 0.02), respectively. There were five (36 %), and two deaths (3 %), respectively, after 10 recurrence-free years. A second resection for recurrence was performed in four patients (29 %), and mean survival was 15.3 years after the first hepatectomy. Although three patients in the non-recurrence group (5 %) developed esophageal and/or gastric varices, seven patients in the recurrence group (50 %) developed varices during 10 years (p < 0.0001). In multivariate analysis, preoperative and 10-year platelet count was identified as a favorable independent factor for maintained recurrence-free survival after a 10-year recurrence-free period following curative hepatic resection of HCC.Conclusions
Recurrence of HCC may occur even after a 10-year recurrence-free period. Long-term follow-up after resection of HCC is important, and should be life-long. Patients with higher preoperative and 10-year platelet counts are more likely to have long-term survival after resection. A low platelet count, related to the degree of liver fibrosis, is a risk factor for recurrence and survival of HCC after curative resection. 相似文献59.

Background
The aim of this study was to investigate the clinical characteristics and outcomes of elderly patients (≥70 years old) undergoing curative hepatectomy for hepatocellular carcinoma (HCC).Methods
Clinicopathological data and treatment outcomes in 100 elderly patients (≥70 years old) and 120 control patients (≤70 years old) with HCC who underwent curative hepatectomy between 2000 and 2011 were retrospectively collected and compared.Results
The overall survival rate was similar between the two groups, but the disease-free survival rate was worse in the elderly group when compared with the control group. Prognostic factors for overall and disease-free survival were the same when comparing the two groups. The elderly group had higher rate of females (p?=?0.0230), higher hepatitis C virus infection rate (p?=?0.0090), higher postoperative pulmonary complication rate (p?=?0.0484), lower rate of response to interferon (IFN) therapy (p?=?0.0203) and shorter surgical time (p?=?0.0337) when compared with the control group. The overall recurrence rate was higher in the elderly group than in the control group (p?=?0.0346), but the rate of recurrence within 2 years after the operation was similar when comparing the two groups.Conclusion
The survival of elderly patients with HCC was similar to that of younger patients. However, the disease-free survival was worse in elderly patients than in younger patients. Aggressive antiviral therapy (e.g. IFN therapy) may be necessary to improve the disease-free survival, even in elderly patients. Additionally, clinicians should be aware of the risk of pulmonary complications in elderly patients after hepatectomy. 相似文献60.
