Objective To systematically assess the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section.Methods The databases including Medline(PubMed),EMbase,Cochrane Library,CNKI and WanFang Data were retrieved by computer.The randomized controlled trials (RCTs) on the efficacy and safety of non-indwelling urinary catheter during perioperative period of cesarean section were comprehensively collected.Two reviewers independently screened literatures,extracted the data and assessed the quality.The Meta-analysis was conducted by using RevMan 5.3 software.Results A total of 5 RCTs involving 1 090 patients were included.The meta-analysis results showed that compared with the indwelling urinary catheter group,although the non-indwelling urinary catheter group increased the incidence rate of urinary retention[RR=11.67,95%CI(2.22,61.24),P<0.01],but significantly decreased the incidence rate of urinary tract infection(UTI) [RR=0.10,95%CI(0.04,0.26),P< 0.01] and incidence rate of initial urination discomfort [RR=0.17,95%CI (0.04,0.74),P=0.02],significantly shortened the initial time of off-bed activities [SMD=-3.68 ,95%CI(-5.25,-2.12),P<0.01]and hospitalization time [SMD=-1.03,95%CI(-1.67,-0.38),P<0.01].There were no significant differences in the operation time[SMD=-0.13,95%CI(-0.32,0.07),P=0.20] and incidence rate of postpartum hemorrhage (PPH)[RR=1.50,95%CI (0.43,5.26),P=0.53],The incidence rates of bladder injury in the two groups were similar.Conclusion According to the evidence of current clinical researches,selecting non-indwelling urinary catheter in elective cesarean section is effective and safe,prompting that indwelling urinary catheter during the perioperative period of cesarean section is selective rather than routine indwelling.

OBJECTIVETo study the effect of light intensity on physiological and biochemical characteristics of Chrysanthemum morifolium at the vegetative stage.

METHODThe dynamic response of physiological and biochemical indexes of Ch. morifolium were measured under different treatments (100%, 80%, 60%, 40% and 20% of the full sunlight) at the vegetative stage.

RESULTThe physiological and biochemical indexes of Ch. morifolium showed dynamic changes with the progress of growth and the increase of the treatment time. The soluble sugar content decreased when the light intensity reduced, and had a significant positive correlation with the light intensity. Soluble protein content rose firstly and fell later, malondialdehyde content increased, superoxide dismutase and catalase activity decreased initially and increased afterwards.

CONCLUSIONProper shading benefits the nitrogen accumulation of Ch. morifolium at the vegetative stage, and reduces the strength of stress condition. The suitable light environment for growth of Ch. morifolium at the vegetative stage is about 80%-60% of full sunlight and the optimum treatment time is 20-40 days.

OBJECTIVETo study the effects of nitrogen (N), phosphorus (P2O5), potassium (K2O) and organic compound fertilizer (OF) on spicas biomass and yield of Prunella vulgaris in order to provide a theoretical basis for good agriculture practice (GAP).

METHODField plot experiments with a 4-variable quadratic orthogonal rotation combination design were adopted, and a function model of spicas yield in P. vulgaris was established.

RESULTThe model analysis showed that spicas yields of P. vulgaris were significantly influenced under the N, P2O5 and K2O applications, among there factors, N had the greatest effects on spicas yield of P. vulgaris, the next was P2O5 and K2O, OF had the smallest effects on spicas yield. At the lower fertility levels, the spicas yields of P. vulgaris were improved along with the increasing of N, P2O5, K2O and OF applications, but the spicas yields decreased when N, P2O5, K2O and OF were applied too much.

CONCLUSIONIn this experiment condition, the spicas yields of P. vulgaris could reach to 722 kg x hm(-2) when the fertilizer rates were N 303. 9-335.1 kg x hm(-2), P2O5 432.5-500.6 kg x hm(-2), K2O 206.6-240.2 kg x hm(-2), OF 2 312.5-2 687.5 kg x hm(-2).

Objective:To explore the effect of nutrition intervention on patients with cervical cancer undergoing chemoradiotherapy.Methods:From October 2016 to October 2018, 60 patients with cervical squamous cell carcinoma confirmed by pathology and treated with radiotherapy and chemotherapy in the First Hospital of Shanxi Medical University were selected. The subjects were randomly divided into the control group (nutrition education + dietary guidance only, 30 cases) and the intervention group (nutrition intervention according to nutrition assessment results, 30 cases) by random number table method. The nutrition assessment for patients was performed with patient-generated subjective global assessment (PG-SGA) scale. The changes of nutrition status, quality of life, incidence of adverse reactions, interruption status of radiotherapy and chemotherapy, and hematological indexes between the two groups in the treatment process were compared.Results:The incidence of moderate and severe malnutrition in the control group and the intervention group in the treatment process was 90% (27/30) and 50% (15/30), respectively, and the difference was statistically significant ( P < 0.01). When the dose of radiotherapy reached 40 Gy, the quality of life of patients in the intervention group was better than that in the control group in some functional fields, symptom fields and overall health status, and the differences were statistically significant (all P < 0.05). The incidence of acute gastrointestinal reaction in the control group and the intervention group was 96.7% (29/30) and 83.3% (25/30), respectively, and the incidence of bone marrow suppression was 96.7% (29/30) and 76.7% (23/30), respectively, and there were statistical differences in the incidence rates of different degrees of acute gastrointestinal reaction and bone marrow suppression between the two groups (both P < 0.05). The interruption rate of radiotherapy in the control group and the intervention group was 26.7% (8/30) and 6.7% (2/30), respectively, and the interruption rate of chemotherapy was 56.0% (14/25) and 26.9% (7/26), respectively, and the differences between the two groups were statistically significant (both P < 0.05). The cycles of chemotherapy completed in the intervention group were more than those in the control group [(4.38±1.10) cycles vs. (3.44±1.58) cycles]. The differences of peripheral blood red blood cells count, hemoglobin, albumin, and total protein between the control group and the intervention group before and after treatment were statistically significant (all P < 0.05), and the decreased values in the intervention group were lower than those in the control group. Conclusion:Nutrition intervention can effectively improve the nutrition status and quality of life of patients with cervical cancer undergoing chemoradiotherapy, reduce the incidence of adverse reactions, chemoradiotherapy interruption rate and decline degree of hematological indexes.

Objective To explore the mediation role of emotional labor in the relationship between workplace ostracism and emotional exhaustion, aiming to provide practical implications to manage workplace ostracism. Methods Using time-lagged survey, a total of 370 valid responses were collected at two time points from the nurses in a general hospital in Chengdu, including the data of demographics, workplace ostracism, emotional labor and emotional exhaustion. Structural equation model (SEM) was employed to test the relationships. Results The means of key variables were: workplace ostracism 1.30 (1.00, 1.73)，surface acting 1.50 (1.00,2.25), deep acting 3.00 (1.33, 4.00), and emotional exhaustion 3.53 (2.60, 4.20). There was a significant positive relationship between workplace ostracism and surface acting (P<0.01), just as well as the relationship with deep acting and emotional exhaustion (P<0.01). Surface acting led to emotional exhaustion of nurses (P<0.01) and mediated the positive relationship between workplace ostracism and emotional exhaustion. Deep acting was not significantly related to emotional exhaustion (P>0.05). SEM analysis demonstrated an acceptable and reasonable model fit. Conclusions The surveyed nurses reported a medium and low level of perceived workplace ostracism and emotional labor, but a high level of emotional exhaustion. Workplace ostracism has a positive effect on nurses' emotional exhaustion via surface acting. Hospital administration should take measure to prevent and intervene in workplace ostracism, provide organizational and supervisory supports to nurses, and particularly enhance nurse's emotional management skills and encourage use of deep acting strategy to minimize the detrimental effects of workplace ostracism.
