ABSTRACT

To evaluate the prognostic value of early white blood cell count (WBC) in patient of acute paraquat poisoning. Methods The literatures about the studies on early WBC and prognosis after paraquat poisoning published in journals at home and abroad were searched. The Chinese literature database contained CNKI, VIP, Wanfang Database, and China Biomedicine Database (CBM), and the journals were limited to the core journals. The foreign language database included PubMed, Embase and Cochrane library clinical controlled trial database. The retrieval date was from the initial publication to April 22nd in 2019, without the limitation of languages. Two researchers independently extracted literature information, and the Newcastle-Ottawa Scale (NOS) was used to evaluate literature quality. The odds ratio (OR), sensitivity, specificity, positive likelihood ratio (PLR), negative likelihood ratio (NLR), diagnostic odds ratio (DOR) and the area under the summary receiver operating characteristic (SROC) were combined and analyzed through the Stata 15.0 software to evaluate the predictive value of early WBC after acute paraquat poisoning. Publication bias was analyzed by Deeks funnel graph. Results There were 7 retrospective studies and 1 prospective study in a total of 980 paraquat poisoning patients, 5 of them were English literatures, the others were Chinese literatures. There was no heterogeneity among the studies (I 2 = 43.5%, P > 0.05). The OR and its 95% confidence interval (95%CI) of the literature was combined through the fixed effect model. The Meta-analysis results were statistically significant (OR = 18.63, 95%CI = 13.63-25.48, P < 0.001), suggesting that the WBC was significantly correlated with the mortality of patients. The combined sensitivity, specificity, PLR, NLR and DOR were 0.75 (95%CI = 0.66-0.82), 0.85 (95%CI = 0.80-0.90), 5.14 (95%CI = 3.86-6.86), 0.29 (95%CI = 0.22-0.39), 17.53 (95%CI = 12.23-25.13) respectively, and the area under the SROC of the WBC was 0.88 (95%CI = 0.85-0.91). Deeks funnel plot was symmetrical (P = 0.21), and there was no obvious publication bias. Conclusion The early WBC has a certain predictive value for the prognosis of acute paraquat poisoning patients.

ABSTRACT

Objective To investigate the current situation of maternal self- efficacy of breastfeeding and explore its influencing factors in Zhengzhou. Methods Using the general condition questionnaires, breast feeding self-efficacy scale, perceived social support scale and Edinburgh postnatal depression scale to assess the situation of 180 puerperas by the convenience sampling in one obstetric hospital of Zhengzhou. Results The total score of maternal breast feeding self-efficacy was(114.04 ± 21.57)points.The frequency of delivery, the way of delivery and feeding ways, the average income of family were effected with breastfeeding self-efficacy. The total score of social support was(68.87 ± 10.43) points, the total score of puerperas depression was(7.61 ± 4.25) points.The social support score had positive correlation with breastfeeding self-efficacy(r=0.423, P<0.01). Puerperas depression had negative correlation with breastfeeding self- efficacy(r=- 0.342, P<0.01). Conclusions The maternal breastfeeding level in Zhengzhou was at a lower level. The level of maternal breastfeeding self-efficacy scale was impacted by maternal social support degree, the degree of depression. Measures should be taken to enhance maternal social support degree, reduce the degree of depression, in order to improve the level of maternal breastfeeding self-efficacy.

ABSTRACT

Objective To determine the relation between the graduation and type of Modic change and low back pain. Methods Ninety-seven patients with low back pain associated with Modic change were enrolled, and the data of clinical were analyzed. The degree of back pain was evaluated by visual analog score (VAS) and Oswestry disability index (ODI). The relation between Modic change and the degree of low back pain was evaluated. Results In 97 patients, the type of Modic change:28 cases (28.9%) were type Ⅰ, 37 cases (38.1%) were type Ⅱ, 11 cases (11.3%) were Ⅱ/Ⅲ, and 21 cases (21.6%) were type Ⅲ. The graduation of Modic change:39 cases (40.2%) were minimal, 34 cases (35.1%) were moderate, and 24 cases (24.7%) were severe. The VAS of type Ⅰ, type Ⅱ, typeⅡ/Ⅲand typeⅢin patients with Modic change were (3.8 ± 0.4), (2.6 ± 0.2), (1.7 ± 0.5) and (1.0 ± 0.6) scores, and there were statistical differences (P0.05). Spearman correlation analysis result showed that the graduation of Modic change had no correlation with the intensity of low back pain (r = 0.351, P>0.05). Conclusions The graduation of Modic change does not directly correlate with the low back pain, but the type of Modic lesion is more important.
