Objective To study the correlation between chronic gastritis with benign mucosal nodular-change,Helicobacter pylori(H.pylori)infection and lymphoid follicles infiltration.Methods During July 1,2004 to June 30,2005 patients with chronic gastritis and benign mucosal nodular-change were identified by chromo-endoscopy with anabrosis indigo carmine staining at the antrum.Multiple biopsies were obtained for H.pylori detection with quick test and for pathology examination of mucosal lymphoid follicles formation and lymphocyte infiltration,as well as H.pylori infection.Results The patients were divided into nodular gastritis group,atrophy gastritis group and verrucous gastritis group with mean age of(31.00?11.62),(58.61?12.14)and(51.29?12.99)years old,respectively.The patients with nodular gastritis were the youngest(P

Objective To investigate the effect of dexmedetomidine on the renal function and the expression of tight junction protein ZO-1 and occluding in the kidney of rats with septicopyemia induced by lipopolysaccharide.Methods Thirty adult male SD rats were randomly divided into 3 groups ( n=10 each):control group( group C) , LPS group ( group M) , and dexmedetomidine group ( group Dex ) .In the groups Dex and LPS, the rats were infused with saline and lipopolysaccharide (5 mg/kg, i.v.) respectively.In the Dex group, after intravenous injection of lipopolysaccharide (5 mg/kg) , the rats were firstly infused the loaded dose of dexmedetomidine (7μg/kg) for 15 minutes, and then changed to 5 μg/kg· min for 30 minutes.Blood samples were collected at 24 h later for measuring TNF-α, IL-1β, Scr and BUN.The kidney tissues were examined by histopathology.The expression of ZO-1 and occludin was detected by Western blot. Results Compared with the group C, the kidney tissue of group M was extensively damaged with tubular dilatation and inflammation, while reduced in the group Dex.Compared with the group C, the expressions of Scr, BUN, IL-1βand TNF-αwere all enhanced in the groups M and Dex ( P <0.05 ) , while the inflammatory factors in the group Dex were significantly lower than those of the group M ( P <0.05 ) .The Results The Western blot analysis showed that the expressions of protein ZO-1 and occludin in the group Dex were significantly higher than those of the group M (P<0.05). Conclusions Dexmedetomidine can improve the renal function of rats with septicopyemia, inhibit the acute renal injury and inflammation, increase the expression of protein ZO-1, and exert certain protective effect on the kidneys.

Objective The purpose of the study was to identify the most frequently used nursing diagnoses,interventions,outcomes and linkages using standardized nursing terminologies for elderly patients with abdominal external hernia surgery.Methods For this study a descriptive design was used.The frequently used NANDA-Ⅰ,NIC,NOC,and NNN linkages were identified through 38 elderly patients with abdominal external hernia surgery who were admitted in hospital from March to August in 2014.Data were analyzed by SPSS17.0.Results The finding showed the most frequently used 5 nursing diagnoses were activity intolerance,impaired tissue integrity,deficient knowledge,chronic pain,and risk for falls,the frequency were 15.51％(38/245),15.51％(38/245),15.10％(37/245),14.69％(36/245) and 14.69％(36/245),the most frequently used 5 nursing outcomes were activity tolerance,ambulation,tissue integrity (skin and mucous membranes),wound healing (primary intention) and knowledge (diet) the frequency were 10.05％(38/378),10.05％(38/378),10.05％(38/378),10.05％(38/378) and 9.79％(38/378); the most frequently used 5 nursing interventions were environmental management (comfort),positioning,exercise therapy (ambulation,) incision site care and environmental management the frequency was all 6.96％(38/546).The most frequently used top 10 NNN linkages were also identified in this study.Conclusions The most frequently used NANDA-Ⅰ,NIC,NOC,and NNN linkages for patients with abdominal external hernia surgery from this study not only offer new knowledge to nurses but also provide scope of evidence-based nursing research in abdominal external hernia clinics.

Objective To detect NRAS gene mutations in patients with acral melanoma, and to analyze their relationship with the prognosis of acral melanoma. Methods Clinical and pathological data were collected from 55 patients with pathologically diagnosed acral melanoma. DNA was extracted from paraffin?embedded specimens from lesions of the 55 patients and 15 patients with nevus. PCR and direct DNA sequencing were performed to detect NRAS gene mutations. Univariate and multivariate analyses were performed using the Cox′s proportional hazards regression model. Results Of the 55 patients, 6(10.9%)carried the Q61R mutation in codon 61 of the NRAS gene. No mutations were found in exon 1 or 2 of the NRAS gene in any of these paraffin?embedded specimens, and none of the pigmented nevus specimens harbored NRAS gene mutations. Of the 6 patients carrying NRAS gene mutations, 4 had lymph node metastasis. Multivariate Cox regression analysis showed that independent factors of poor prognosis included advanced clinical stage(RR = 2.54, 95% CI: 1.062- 6.066, P < 0.05), not receiving surgical resection(RR = 2.98, 95% CI:1.316- 3.525, P < 0.05), and carrying NRAS gene mutations (RR = 2.73, 95% CI: 0.932- 3.257, P < 0.05). Conclusions NRAS gene mutations may be associated with lymph node metastasis in patients with acral melanoma. The prognosis of acral melanoma may be associated with clinical staging, treatment strategies and NRAS gene mutations. Additionally, NRAS gene mutations may serve as a new index for predicting prognosis of acral melanoma.
