Objective To establish a reasonable method to evaluate nursing quality with both the quantity and quality of nursing taken into account.Methods Quantity indexes of nursing were analyzed with decision tree method (CHAID)in SPSS18.0,which included the number of patients admitted to wards,first grade' s nursing days,critically ill patients,emergencies,operations,intravenous infusions,intramuscular injections,oxygen inhalations,urinary tract catheterizations,gastric tube catheterizations,enemas and the average turnover rate of beds.After the quantity analysis,the nursing units were divided into different groups according to their workload.Then,we made a comprehensive evaluation of nursing quality with 12 indicators on the same group.Results Decision tree analysis can identify hierarchy relationship of various nursing quantity indicators and high-priority work quantity variables.Furthermore,it can establish the hierarchical rule based on the distribution of high-priority variables,and serve the purpose of classifying nursing units based on nursing workload.Conclusion The decision tree method can provide a same-level nursing workload platform for quality examination.This has minimized the influence of nursing workload discrepancies on nursing quality examination,and made nursing quality more comparable with nursing workload units of the same level,thus a scientific method for comprehensive nursing quality evaluation.

OBJECTIVETo observe the analgesic effect of electroacupuncture (EA) on collagen-induced arthritis (CIA) rats and its regulating effect on inflammation reaction and the endogenous opioid system of synovial tissues. Methods A total of 30 healthy male Wistar rats were randomly divided into a control group, a model group and an EA group, 10 rats in each one. The chronic pain model of CIA rats was made by cattle type-II collagen in the model group and EA group. Rats in the EA group were treated with EA at "Zusanli" (ST 36) and "Kunlun" (BL 60) for 30 min from 16th day after model establishment, once a day for consecutive 10 days. Rats in the control group did not receive any treatment. Rats in the model group were treated with fixation as the EA group. Threshold of pain, arthritis index, paw swelling were measured before model establishment and 16 d, 20 d, 23 d and 25 d after model establishment. The levels of beta-endorphin (β-END), met-enkephalin (met-ENK), dynorphin A (Dyn A) were measured by radioimmunoassay; the mRNA expressions of mu opioid receptor (MOR), kappa opioid receptor (KOR) and delta opioid receptor (DOR) in synovial tissues of CIA rats were detected by I quantitative polymerase chain reaction (qPCR).

RESULTSCompared with the control group, threshold of pain was reduced (all P<0. 01), arthritis index was increased (all P<0. 01) and paw swelling was increased (all P<0. 01) in the model group on the 16th day, 20th day, 23rd day, 25th day after model establishment. Compared with the model group, the threshold of pain was increased in the EA group (all P<0. 01), arthritis index and paw swelling were reduced (all P<0. 01) on the 23rd day and 25th day after model establishment. Compared with the control group, the level of Dyn A in synovial tissues of CIA rats was increased in the model group (P<0. 01); the mRNA expressions of MOR, KOR and DOR were down-regulated lower than 0. 5 fold of normal level. Compared with the model group, the level of β-END in synovial tissues of the knee joint was increased in the EA group (P<0. 05), and the mRNA expressions of MOR, KOR and DOR in synovial tissues of CIA rats were up-regulated more than 2 folds of normal level.

CONCLUSIONThe intervention of EA on chronic pain of CIA rats is superior, which is likely to be related with effects of EA on anti-inflammation and up-regulation of synovial tissue β-END and MOR, KOR, DOR.

Objective:To investigate the effect of O-6-methylguananine-DNA methyltransferase (MGMT) gene promoter methylation status on the treatment and prognosis of elderly patients newly-diagnosed with glioblastoma (GBM).Methods:Clinical data of 65 newly-diagnosed GBM patients admitted to Tianjin Huanhu Hospital from January 2012 to December 2018 were retrospectively analyzed. All patients received intensity-modulated radiotherapy after surgery and 49 patients received temozolomide (TMZ) monotherapy. All patients were divided into the MGMT(+ ) group and MGMT(-) group according to the methylation status of MGMT promoter. Kaplan- Meier method and log-rank test were used for univariate survival analysis, and Cox regression model was used for multivariate prognostic analysis. Results:The median overall survival (OS) for all patients was 18.0 months. The median OS was 27.0 months and 15.3 months in the MGMT(+ ) group and MGMT(-) group, respectively. Univariate analysis revealed that tumor number, MGMT promoter methylation, postoperative concurrent chemoradiotherapy were significantly related to clinical prognosis ( P=0.029, P=0.001 and P<0.001). In multivariate analysis, tumor number and postoperative concurrent chemoradiotherapy were identified as significant prognostic factors for OS ( P=0.037, P=0.004). In the MGMT(+ ) group, the median OS was 27.0 months for patients receiving concurrent chemoradiotherapy and 12.0 months for radiotherapy alone ( P=0.040). In the MGMT(-) group, the median OS was 17.0 months for concurrent chemoradiotherapy patients and 10.0 months for radiotherapy alone ( P=0.122). Conclusions:MGMT promoter methylation status is significantly associated with longer OS in elderly GBM patients. Conventional fractional radiotherapy combined with concurrent and sequential TMZ chemotherapy probably yields better survival benefits.

Objective To observe the histopathologic injury of small intestine and intestinal permeability in chronic renal failure (CRF) rats. Methods Twenty male Sprague-Dawley rats were randomly assigned to CRF group (n=10) and control group (n=10). 5/6 nephrectomy was used to establish CRF rats, while sham operation for control. Blood biochemistry was regularly monitored until CRF model was successfully established. The model rats were fed with lactulose (L) and mannitol (M) through intragastric administration. Urine was collected after 6 hours, and the concentration of lactulose and mannitol in urine was measured using high pressure liquid chromatograph with refractive index detector (HPLC-RID), and the ratio of urinary excretion of L/M was calculated to evaluate intestinal permeability. Small intestinal mucosa were stained by hematoxylin-eosin (HE) and observed with light microscope (villus height, thickness of muscle layer and villus count), histological damage score was used to evaluate intestinal injury. Results The L/M ratio of CRF group was higher than that of control group (1.75±0.11 vs 1.20±0.06, P<0.01). The small intestinal mucosal villus height and thickness of muscle layer in CRF group were higher (P<0.01), and the number of villi was lower compared to control group (P<0.01). The score of histopathologic intestine damage of CRF group was higher than that of control group (1.00±0.71 vs 0, P<0.01). Conclusion The intestinal permeability of CRF rats is increased with varying degrees of intestinal damage.
