Purpose: The aim of this study was to evaluate the effects of auricular acupressure on sleep quality and pruritus in patients undergoing hemodialysis and to propose an effective and evidence-based nursing intervention. Methods: This was a single-blind, nonequivalent, group comparison study with 42 participants. The experimental period was a total of 8 weeks, and five different acupressure sites were applied in each group. Dependent variables were measured before the intervention, at the 4th week of the intervention, and at the 8th week of the intervention. Results: There were significant differences in the Pittsburgh sleep quality index, total sleep time, sleep efficiency, sleep onset latency, light sleep, deep sleep, number of awakenings, serum melatonin levels, subjective pruritus and skin hydration. No significant difference was found in skin pH between the two groups. Conclusion Auricular acupressure was found to be an effective nursing intervention to improve sleep quality and to reduce pruritus in patients undergoing hemodialysis.

Brugada syndrome is an arrhythmic syndrome characterized by right bundle branch block, ST segment elevation in the precordial lead (V1-V3), and sudden death caused by ventricular fibrillation, which is not effectively prevented by anti-arrhythmic drug therapy. We are reporting a 30-year-old male patient with Brugada syndrome who got an exploratory laparotomy and a tenorrhaphy due to stab wound which was managed with general anesthesia and brachial plexus block without any complications.

Lemierre syndrome is caused by acute oropharyngeal infections with secondary septic thrombophlebitis of the internal jugular vein and is characterized by frequent metastatic infections. A 56-year-old man presented with severe reddish inflammatory swelling of the right cervical soft tissue. Thrombophlebitis in the right internal jugular vein and multiple pulmonary embolisms were identified on neck and chest computed tomography (CT). He was treated with antibiotics and heparin for 4 weeks and then discharged without other complications.

A 43-yr-old patient visited our department with intermittent chest pain he had suffered with for the past 2 months. Chest CT showed an egg shaped mass in the left chest wall. Local resection was performed for distinguishing the mass from a neurogenic tumor. The diagnosis was periosteal Ewing sarcoma of the rib. Since there was no evidence of metastasis based on the PET-CT, a 2nd operation was done with wide resection and thoracoplasty. The patient was then treated with combined chemotherapy. There has been no local recurrence for the last 1 year. The patient's age and tumor origin were distinct from the usual characteristics of Ewing's sarcoma. Periosteal Ewing's sarcoma of the rib has rarely been reported. We report here on a case of periosteal Ewing's sarcoma of the rib along with a review of the relevant medical literature.

Objective To find out the arsenic pollution in Yangzonghai lake and its influence to the surrounding drinking water source and the local food and to provide a scientific basis for arsenic pollution control,drinking water and food safety. Methods Arsenic monitoring were carried out in 10 points of Yangzonghai lake,45 water sources within 5 km of Yangzonghai lake, and locally produced food. Results From September 2008 to December 2009, the water arsenic concentrations of Yangzonghai lake ranged 0.06 - 0.18 mg/L, the average arsenic concentrations were 0.12 mg/L and 0.10 mg/L for 2008 and 2009, respectively, the value of 2009 was higher, and the difference was statistically significant(t = 3.284, P ＜ 0.05). There were no significant difference in the average of arsenic concentration of Yangzonghai lake between the dry and rainy season in 2009(t = 0.905, P ＞0.05). The arsenic concentrations from the No. 3 spring water ranged from 0.12 - 30.36 mg/L. After a peak value early in October 2008, the No. 3 spring water showed a downward trend month by month. In 2008 the average arsenic concentration was 23.92 mg/L, 2009 was 2.41 mg/L, down 89.92% over the previous year, the difference was statistically significant(t = 9.582, P ＜ 0.05 ). In January and February 2009, the average arsenic concentration (11.96 mg/L) was significantly higher than those of March-December(0.50 mg/L, t = 57.759, P＜ 0.05). In Yangzong town, the arsenic concentration in the drinking water and river met the national drinking water health standards. Among 78 samples monitored of the locally produced food in Yangzong town, 77 passed, with a pass rate of 98.72%. Conclusions Arsenic contamination has been effectively controlled. The drinking water and local food production has not been contaminated by arsenic except aquatic products in Yangzonghai Lake. It is recommended to take effective measures to prevent water contamination.

Objective To explore the effect of low-intensity pulsed ultrasound (LIPUS) on long bone fracture healing and to examine caveolin-1 gene expression in the radius defects of rabbits.Methods A total of 24 New Zealand rabbits with 3-mm bone defects at lower 1/3 in both radii were randomly assigned to 4 groups (n=6).Daily LIPUS treatment was performed to the right fracture sites at a intensity of 30 mW/cm2 for 20 minutes,while the left sites received sham treatment with power off.To assess the effects of LIPUS on bone defects,X-ray imaging and hematoxylin-eosin staining were applied 7,14,21,28 days after the surgery.Additionally,the immunohistochemical staining was used to determine the subcllular localization of caveolin-1 and semi-quantify the caveolin-1 level,qPCR was performed to detect the mRNA level of caveolin-1,gene Col2a1 and Col10a1,and osteocalcin.Results On day 14,the radiological score of the right radii and mineralized callus area were significantly higher than that of the left ones,both of them were elevated with time flied.Histological examination suggested that the differentiation and apoptosis of chondrocytes along with the formation and bridging of the bone trabeculas appeared earlier in the right radius defects.The immunohistochemical staining showed that on day 7 and 14,the level of caveolin-1 increased with the proliferation and differentiation of condrocytes,and was significantly higher in callus tissues on the right sites.On day 21 and 28,the mesenchymal stem cells migrated to the surface of cartilage matrix started to differentiate into osteoblasts,the level of caveolin-1 decreased,and was significantly lower on the right sites.The result of qPCR indicated that compared with the left sites the caveolin-1 gene expression on the right sites was significantly higher on day 7,while significantly lower on day 21.The mRNA expression levels of Col2a1,Col10a1 and osteocalcin on the right sites were significantly higher on day 7 and 14,but they were significantly lower on day 21 and 28,except for Col10a1 on day 28.Conclusions Advancing endochondral ossification is considered to be a crucial mechanism during long bone fracture healing promoted by LIPUS.The caveolin-1 gene expression first increased in the chondrocytes then decreased in the mesenchymal stem cells during the process.

S-phase kinase-associated protein 2 (Skp2), which plays a role in cell cycle regulation, is commonly overexpressed in a variety of human cancers and associated with poor prognosis. However, its role in nasopharyngeal carcinoma (NPC) is not well understood. In this study, we examined the clinical significance of Skp2, with a particular emphasis on overall survival (OS) and disease-free survival (DFS), in NPC cases in South China, where NPC is an epidemic. Additionally, we explored the function of Skp2 in maintaining a cancer stem cell-like phenotype in NPC cell lines. Skp2 expression was assessed for 127 NPC patients using tissue microarrays and immunohistochemistry and analyzed together with clinicopathologic features, OS, and DFS. Skp2 expression was detectable, or positive, in 75.6% of patients. Although there was no correlation between Skp2 and any clinicopathologic factor, Skp2 expression significantly portended inferior OS (P = 0.013) and DFS (P = 0.012). In the multivariate model, Skp2 expression remained significantly predictive of poor OS [P = 0.009, risk ratio (RR) = 4.06] and DFS (P = 0.008, RR = 3.56), and this was also true for clinical stage (P = 0.012 and RR=3.201 for OS; P = 0.002 and RR=1.94 for DFS) and sex (P = 0.016 and RR=0.31 for OS; P = 0.006 and RR = 0.27 for DFS). After Skp2 knockdown, a colony formation assay was used to evaluate the self-renewal property of stem-like cells in the NPC cell lines CNE-1 and CNE-2. The colony formation efficiency in CNE-1 and CNE-2 cells was decreased. In Skp2-transfected CNE-1 and CNE-2 cells, side population (SP) proportion was increased as detected by flow cytometry. Skp2 is an independent prognostic marker for OS and DFS in NPC. Skp2 may play a role in maintaining the cancer stem cell-like phenotype of NPC cell lines.

We describe two cases of pulmonary arterial hypertension (PAH) that occurred under dasatinib treatment and were resolved after dasatinib discontinuation. Two patients with chronic phase chronic myeloid leukemia (CML) were switched to dasatinib therapy because of hematological progress while receiving imatinib. These patients had New York Heart Association (NYHA) functional class II dyspnea with elevated right ventricular systolic pressure (RVSP), which progressed under dasatinib treatment. After dasatinib treatment was discontinued, subjective symptoms were improved to NYHA functional class I and the follow-up transthoracic Doppler echocardiography showed improved RVSP. Treatment with an alternate tyrosine kinase inhibitor was initiated and had been continued without development of dyspnea or elevation of RVSP. This report suggests that dasatinib can cause the reversible PAH, therefore, routine cardiopulmonary evaluation before and during treatment with dasatinib may be needed in CML patients with clinical manifestations.

Aged garlic extract (AGE) is known to have a protective effect against immune system, endothelial function, oxidative stress and inflammation. We examined the effects of exercise with and without aged garlic extract administration on body weight, lipid profiles, inflammatory cytokines, and oxidative stress marker in high-fat diet (HFD)-induced obese rats. Forty-five Sprague-Dawley rats were fed either a HFD (HFD, n = 40) or a normal diet (ND, n = 5) for 6 weeks and thereafter randomized into ND (n = 5), HFD (n = 10), HFD with AGE (n = 10), HFD with Exercise (n = 10), or HFD with Exercise+AGE (n = 10) for 4 weeks. AGE groups were administered at a dose of 2.86 g/kg.body weight, orally. Exercise consisted of running 15-60 min 5 days/week with gradually increasing intensity. AGE (P < 0.01), Exercise, and Exercise+AGE (P < 0.001) attenuated body weight gain and food efficiency ratio compared to HFD. Visceral fat and liver weight gain were attenuated (P < 0.05) with all three interventions with a greater effect on visceral fat in the Exercise+AGE than AGE (P < 0.001). In reducing visceral fat (P < 0.001), epididymal fat (P < 0.01) and liver weight (P < 0.001), Exercise+AGE was effective, but exercise showed a stronger suppressive effect than AGE. Exercise+AGE showed further additive effects on reducing visceral fat and liver weight (P < 0.001). AGE significantly attenuated the increase in total cholesterol and low-density lipoprotein-cholesterol compared with HFD (P < 0.05). Exercise+AGE attenuated the increase in triglycerides compared with HFD (P < 0.05). Exercise group significantly decrease in C-reactive protein (P < 0.001). These results suggest that AGE supplementation and exercise alone have anti-obesity, cholesterol lowering, and anti-inflammatory effects, but the combined intervention is more effective in reducing weight gain and triglycerides levels than either intervention alone.
