Objective: To compile and evaluate the Chinese version of perioperative nursing quality assessment scale, detect and verify the reliability and validity of evaluation scale, and establish a scientiifc evaluation system. Methods: We applied Tuija Leinonene and Helena Leino-kilpi scales as the theoretical framework, and established perioperative nursing quality assessment scale by translation, language study, and expert consultation. hTe questionnaire survey population was 276 patients who had surgery and 200 nurses working in the operating rooms at the 3 Affliated Hospitals of Central South University. hTe scale was tested validity and reliability. Results: Perioperative nurse quality evaluation scale consisted of 32 items and 7 dimensions, including body care, receive information, support, respect, medical staff characteristics, environment and nursing process. The test-retest reliability of scale was 0.977 for patients and 0.997 for nurses. hTe split half reliability of scale was 0.761 for patients and 0.887 for nurses. hTe Cronbach's α of total scale for the patients was 0.918, and the Cronbach's α of factors was 0.658-0.838. hTe Cronbach's α of total scale for the nurses was 0.932, and the Cronbach's α of factors was 0.650-0.836. hTe correlation coeffcient of scale for the patients was 0.363-0.603; the factors and the total correlation coeffcient was 0.535-0.788. hTe correlation coeffcient of scale for the nurses was 0.410-0.700; the factors and the total correlation coeffcient was 0.743-0.902. Conclusion: The Chinese version of the perioperative nursing quality assessment scale is a measurement instrument with a high level of validity and reliability for Chinese society and can be used to determine the quality of perioperative nursing care in our country.

Objectives To study the psychological characteristics of children with attention deifcit hyperactivity disorder (ADHD). Methods Human ifgure drawings (HFD) as a projective technique was performed in 107 children with ADHD aged (8.69 ±1.48) years old (6.5~11.5 years), and 107 matched healthy children. Characteristic features of the HFDs in children with ADHD, and correlations between emotional indicators of the HFDs and factors of child behavior checklist (CBCL) were assessed and com-pared with the control group. Results Signiifcant differences in emotional index were found between ADHD and healthy chil-dren, including bad body composition, short arms, long arms, big ifgure, omission of hands and omission of feet (P<0.05). Nega-tive correlation was found between the HFDs emotional index and the factors of activity and social ability in the CBCL (P<0.05), but a positive correlation was found between the HFDs emotional index and behavioral problem (P<0.05). Conclusion Human ifgure drawings can relfect some emotional characteristics of children with ADHD, and when combined with CBCL, it can pro-vide evidence for diagnosis and intervention for ADHD.

Objective To explore the role of protein kinase C(PKC) to regulate the activation of nuclear factor-?B(NF-?B)in T lymphocyte in children with acute idiopathic thrombocytopenic purpura(ITP).Methods Sterility peripheral blood was collected from acute ITP children(n=30)and healthy children(n=30).T lymphocytes were isolated and purified,and divided into 3 groups:control group,PMA group stimulated with PMA,PMA plus H-7 group stimulated with PMA and H-7.The expression of NF-?B and inhibitor protein-?B(I-?B)was detected by immunohistochemical staining and Western blot,respectively.Results The percentage of cells with active NF-?B was significantly higher and the expression level of I-?B was significantly lower in acute ITP PMA group than that in acute ITP control group and normal PMA group,respectively(all P

Objective:To investigate the risk factors and predictive effect of lateral cervical lymph node metastasis of papillary thyroid carcinoma (PTC) by applying the concept of central lymph node metastasis intensity.Methods:This study retrospectively analyzed integrated clinic data of 106 cases with PTC undergoing treatment of cervical lymph node dissection in Department of Thyroid and Breast Surgery of the Affiliated Hospital of Inner Mongolia Medical University from Dec. 2009 to Jan. 2014. Based on whether lateral cervical lymph nodes had metastasis, patents were classified into lymph node metastasis positive group ( n=75 cases) , lymph node metastasis negative group ( n=31 cases) . This study explored metastasis-associated risk factors of age, gender, triiodothyronine (T3) , thyroxine (T4) , free triiodothyronine (FT3) , free thyroxine (FT4) , thyroid stimulating hormone (TSH) , thyroglobulin antibody (TGAb) , thyroid peroxidase antibody (TPOAb) , whether combined with Hashimoto’s disease, tumor location, infringing the membrane, mulifocality, tumor glands distribution, tumor diameter, number of central lymph node metastases, central lymph node metastasis ratio, and analyzed the effects of central lymph node metastasis intensity on lateral cervical lymph node metastasis. SPSS 21.0 software was used for data analysis, the metering data of normal distribution was expressed as ± s, and t test was used for comparison between groups. Count data was expressed as a rate (composition ratio) , and comparisons between groups were performed by χ2 test or Fisher exact probability method. Results:Univariate analysis found that whether combined with Hashimoto’s disease ( P=0.087) , tumor location ( P=0.249) , tumor glands distribution ( P=0.219) and tumor diameter ( P=0.224) had no correlation with lateral cervical lymph node metastasis, which showed no statistical significant differences ( P>0.05) . Infringing the membrane ( P=0.030) , mulifocality ( P=0.031) , number of central lymph node metastases ( P=0.022) and central lymph node metastasis ratio ( P=0.001) had correlation with lateral cervical lymph node metastasis, which showed statistical significant differences ( P<0.05) . The number of central lymph node metastases and the increase of central lymph node metastasis ratio had positive correlation with the occurrence of lateral cervical lymph node metastasis; when the number of central lymph node metastases was ≥4 or (and) the central lymph node metastasis ratio was ≥20%, the incidence of lateral cervical lymph node metastases increased significantly, and the difference was statistically significant ( P<0.05) . Conclusion:Infringing the membrane and mulifocality are risk factors for lateral cervical lymph node metastasis. When central lymph node metastasis intensity: number of metastases ≥4 or (and) metastasis ratio ≥20%, lateral cervical lymph node dissection is recommended.

Objective To explore the therapeutic mechanisms of nitric oxide donor (SIN 1) in ischemic acute renal failure (IARF). Methods The effects of SIN 1 on intercellular adhesion molecule 1 (ICAM 1) expression and inflammatory cell infiltration in rat kidney after ischemia/reperfusion (I/R) injury were examined using ICAM 1, ?2 integrin polyclonal antibody, and immunohistochemistry. The renal functions were measured simultaneously. Results Progressive increased expression of ICAM 1 was found in kidneys, especially in vasa recta, after IR injury. ?2 integrin positive cells increased simultaneously in the outer medulla. The two indexes reached the peak values at 24 h after I/R injury. SIN 1 infusion at the beginning of reperfusion could remarkably inhibit the enhanced ICAM 1 expression, reduce the local infiltration of inflammatory cells, and ameliorate the renal functions. Conclusion NO donor can inhibit the renal expression of ICAM 1 and the infiltration of leukocytes after ischemia reperfusion injury, which may play an important role in the treatment of ischemic acute renal failure.

Aim To investigate the changes in the expression of protein kinase C gamma (PKC?), phosphorylated cAMP response element binding protein(pCREB)and immediate-early gene(c-fos and c-jun) in the spinal cord in formalin-induced inflammatory pain and study the effect of agmatine on the changes of PKC? activation, phosphorylation of CREB and expression of c-fos and c-jun.Methods Rats were decapitated at 10, 20 min or 2 h after intraplantar injection of 50 ?l 5% formalin and L_4, 5 spinal cords were dissected. Immunohistochemistry and western blotting analyses were used to observe the expression of PKC?, pCREB, c-fos and c-jun in the spinal dorsal horn and the effect of agmatine on the changes of their expression. Results Unilateral peripheral inflammation induced PKC? activation and CREB phosphorylation bilaterally while c-fos and c-jun expression ipsilaterally in rat spinal cord. PKC activity increased in membrane fractions with unchanged levels in the cytosolic fractions. Pretreatment intraperitoneally with 160 mg?kg-1 agmatine 15 min before inflammation significantly inhibited the activation of PKC? in the membrane fraction, suppressed the phosphorylation of CREB and the expression of c-fos and c-jun. Conclusion The mechanism of the analgesic effect of agmatine may be associated with inhibiting PKC? activation in the plasma membrane, CREB phosphorylation, c-fos and c-jun up-regulation which play roles in the hyperalgesia with peripheral inflammation.
