Objective:To analyze the predictive value of combined detection of color ultrasound parameters,coagulation indicators and soluble leukocyte antigen G (sHLA-G) on pregnancy outcomes of patients with threatened abortion after tocolysis. Methods:A total of 100 patients,who met the diagnostic condition of threatened abortion and admitted to Dongguan People's Hospital Xiegang Branch between January 2019 and January 2021,were selected. They were divided into success group and failure group according to pregnancy outcomes after tocolysis,with 50 cases in each group. The color ultrasound parameters,coagulation indicators and sHLA-G levels were measured,and logistic regression and receiver operating characteristic (ROC) curve were used to analyze predictive value of the above indicators on the pregnancy outcomes of patients with threatened abortion after tocolysis. Results:The inner diameter of the yolk sac (5.37±1.02) ml and sHLA-G level (65.37±12.38)U/ml in success group were significantly higher than yolk sac and sHLA-G level in failure group,and the differences were statistically significant (t=12.566,19.989,P<0.05),respectively. The resistance index (RI) and D-dimer (D-D) levels of success group were significantly lower than those of failure group,and the differences were statistically significant (t=20.344,17.603,P<0.05),respectively. The inner diameter of the yolk sac,RI,D-D and sHLA-G were risk factors that affected the pregnancy outcome of patients with threatened abortion after tocolysis (OR=2.349,2.115,2.266,2.21,P<0.05),respectively. The sensitivity,specificity,accuracy and area under curve (AUC) of the combined detection of inner diameter of yolk sac,RI,D-D and sHLA-G in predicting pregnancy outcomes of patients with threatened abortion after tocolysis were 96.00％,98.00％,97.00％ and 0.991,respectively,which were significantly higher than those of the singly each indicator (t=2.514,3.628,4.258,6.134,P<0.05). Conclusion:The combined detection of inner diameter of yolk sac,coagulation indicators and sHLA-G has predictive value for the pregnancy outcomes of patients with threatened abortion after tocolysis. Moreover,the combined detection of inner diameter of yolk sac,RI,D-D and sHLA-G levels can significantly improve the sensitivity,specificity and accuracy of prediction.

Objective To explore the influence of Clostridium butyricum on the expression of vascular endothelial cell growth factor (VEGF) and its receptor 2 (VEGFR-2), proliferating cell nuclear antigen (PCNA), and tight junction protein claudin-2 in intestinal tissue in newborn rat with necrotizing enterocolitis (NEC). Methods Forty-eight-hour-old Sprague-Dewley (SD) rats were randomly divided into model group, control group, low-dose group, mid-dose group, and high-dose group, 12 rats each. Rats in each group were fed with milk substitute. The NEC model were created by hypoxia and cold stimulation for 3 consecutive days in model group, low-dose group, mid-dose group, and high-dose group. Meanwhile, low-dose group, mid-dose group, and high-dose group were intervened by being fed with Clostridium butyricum 0.2, 0.4, and 0.8 g/(kg·d), respectively. All rats in each group were sacriifced on day 4 and the intestines tissue was obtained. The pathological changes had been observed. The expression of VEGF, PCNA, and claudin-2 were detected by immunohistochemistry. The expression of VEGFR-2 was detected by RT-PCR. Results The intestines pathological scores was signiifcantly different among ifve groups (P?0 . 05 ). Conclusion The expression of VEGF, VEGF-2 , and claudin-2 were higher in rats with NEC, while the expression of PCNA was lower. Supplementation of Clostridium butyricum may protect newborn rats by its act on these factors.

Objective To determine whether the fixation method of electrode of the improved pediatric video electroencephalogram (VEEG) is better than the traditional fixation method. Methods A total of 746 children patients who needed VEEG monitoring were divided into the experimental group and the control group with random digit table with 373 patients in each group. Improved fixation method and traditional fixation method of electrode were adopted during VEEG monitoring in the experimental group and the control group. The advantage and disadvantage of the two fixation method were compared through evaluation of skin injury of scalp and deltoideus triangularis, electrode loss and electrode breakage. Results The incidence of skin injury of scalp and deltoideus triangularis, electrode loss and electrode breakage in the experimental group were 7, 0, 29, and 12, which were less than 29, 6, 71, and 37 of the control group, the differences were of statistical significance (χ2=14.126, 20.371, 13.652, P<0.01 or 0.05). Conclusions Improved electrode fixation method during pediatric VEEG can avoid skin injury of scalp and deltoideus triangularis, reduce electrode loss and electrode breakage, besides, it also can reduce medical cost and discomfort of children. The modified electrode fixation method proved to be superior to the traditional method and it is worth popularization and application.

Objective:To explore the related risk factors of antepartum depression and anxiety,and to provide the theoretical support for early screening,clinical intervention and prevention of antepartum depression and anxiety.Methods:At the time of 28 weeks of prenatal examination,the Edinburgh Postnatal Depression Scale (EP-DS),Self-Rating Anxiety Scale (SAS)were used to survey 2112 pregnant women who were selected from Maternal and Child Health Hospital of Kunming City.Non conditional logistic regression analysis was used to explore the re-lated risk factors of prenatal depression and anxiety.Results:At the 28 weeks of pregnancy,the detection rate of de-pression symptoms and anxiety symptoms were 25.4% and 6.6%.Logistic regression analysis showed that the risk factors for perinatal depression symptoms were younger age (OR =0.80,95%CI:0.68 -0.94),not stick to work during pregnancy (OR =1.18,95%CI:1.02 -1.36),not satisfied with the living environment (OR =1.50,95%CI:1.23 -1.83),expectations for boys (OR =0.86,95%CI:0.77 -0.96),not only daughter (OR =1.37,95%CI:1.06 -1.76),unplanned pregnancy (OR =1.38,95%CI:1.10 -1.72).The risk factors for perinatal anxiety symp-toms were being not satisfied with the living environment (OR =1.64,95%CI:1.19 -2.26),not harmonious with her husband (OR =2.01,95%CI:1.20 -3.37),unplanned pregnancy (OR =1.50,95%CI:1.05 -2.14).Conclu-sion:It suggests that the pregnant women with younger age,less working during pregnancy,being not satisfied with the living environment,having more expectations for boys,being not only daughter,with unplanned pregnancy are more likely to suffer from antepartum depression;those being not satisfied with living environment,having harmoni-ous relation with her husband,and with unplanned pregnancy are more likely to suffer from antepartum anxiety.

Objective To explore the cooperation of video electroencephalogram (VEEG) and nursing in the use of correcting iatrogenic refractory epilepsy in children.Methods We implemented the following nursing measures:making an appointment to understand the patients' history and seizures; controlling the condition of VEEG seriously to reduce the interference of potential difference; performing the recording of the background wave of the VEEG with eyes test,hyperventilation,flash stimulation and other evoked tests; giving experiment to induce seizure,such as vertical test,hot water stimulation and so on,which was according to the characteristics of children with seizures; informing the parents and children to review the VEEG and perfect the relevant inspection to correct the diagnosis of epilepsy clearly.Results 5 patients in 9 cases had corrected the diagnosis and classification of epilepsy.2 cases who had been diagnosed as BECT (benign childhood epilepsy with centrotemporal spikes) appeared new type of seizure in the course of disease,then we diagnosed the variant of BECT,according to the characteristics of VEEG.2 cases were excluded the diagnosis of epilepsy.Conclusions During application of VEEG in the use of correcting iatrogenic refractory epilepsy in children,we should pay attention to the communication with children and parents,strictly implement monitoring standard,give testing stimulation according to characteristics of children,so that we can get real and satisfying monitoring results.
