Objective: To explore the relationship between the expression of serum B-type natriuretic peptide(BNP) levels and cardiac function, heart failure(HF) in children with ventricular septal defect of congenital heart disease(CHD). Methods: From October 2013 to July 2017, 150 children with ventricular septal defect of CHD who were treated in Yuncheng Central Hospital were selected, and they were divided into no HF group(n=40), mild HF group(n=46) and moderately severe HF group(n=64) according to the New York university pediatric heart failure index(NYU PHFI) evaluation standard.Meanwhile, 148 healthy children were selected as control group.The serum BNP levels, left ventricular ejection fraction(LVEF), left ventricular ejection fraction shortening rate(LVFS), left ventricular end diastolic diameter index(LVEDDI) and cardiac output index(CI) were measured in all subjects.The levels of BNP, LVFS, LVEF, LVEDDI and CI in the study group were compared with those in the control group.The levels of BNP, LVEF, LVFS, LVEDDI and CI in children with CHD ventricular septal defect were compared.The relationship between the level of BNP and LVEF, LVFS, LVEDDI and CI in patients with ventricular septal defect of CHD was analyzed. Results: The serum level of BNP in the study group was (268.47±25.48)ng/L, the levels of LVEF, LVFS, LVEDDI and CI in the study group were (55.56±4.23)%, (27.96±2.74)%, (77.56±6.54)mm/m², (3.35±0.41)L·min^-1·(m²)^-1, respectively.The serum level of BNP in the control group was (33.41±6.21)ng/L, and the levels of LVEF, LVFS, LVEDDI and CI in the control group were (65.43±5.12)%, (36.24±3.23)%, (57.32±5.31)mm/m², (4.27±0.46)L·min^-1·(m²)^-1, respectively.The serum levels of BNP and LVEDDI in the study group were significantly higher than those in the control group(t=109.077, 29.306, all P<0.05), while the levels of LVEF, LVFS and CI in the study group were significantly lower than those in the control group(t=18.152, 23.875, 18.231, all P<0.05). With the increased severity of HF, the levels of BNP and LVEDDI were increased, while the levels of LVEF, LVFS and CI were gradually decreased(F=332.232, 245.400, all P<0.05). The level of serum BNP was negatively correlated with LVEF, LVFS, CI(r=-0.705, -0.692, -0.718, all P<0.05), but it was positively correlated with LVEDDI and HF(r=0.721, 0.735, all P<0.05). Conclusion The level of serum BNP in patients with ventricular septal defect of CHD is correlated with cardiac function indicators, and serum BNP is positively correlated with HF in children with ventricular septal defect of CHD, which plays an important role for the diagnosis, treatment and prognosis of HF.

Objective To evaluate the effect of percutaneous coronary intervention (PCI) on anxiety and depression among patients with coronary heart disease (CHD). Methods A total of 600 CHD patients were divided into the stent group (n = 400) and the non-stent group (n = 200) according to stent implantation during coronary angiography, and 400 cases in the stent group were further divided into the intervention group (n = 200) and the non-intervention group (n = 200) according to post-stenting psychological interventions. The anxiety and depression were scored using self-rating anxiety and depression scales 1 day after admission, 1 day after PCI and at discharge from hospital, and the anxiety and depression scores were compared at different time points. Results The mean age, sex ratio, hemoglobin, total cholesterol, triglyceride, high-density lipoprotein cholesteroland low-density lipoprotein cholesterol levels were comparable among the three groups (P > 0.05). There were no significant differences among the three groups in terms of anxiety or depression scores one day after admission (P > 0.05). One day after PCI, the anxiety and depression scores were significantly higher among CHD patients in the intervention and non-intervention groups than in the non-stent group (P < 0.05), and the anxiety (t = 11.21, P < 0.01; t = 9.96, P < 0.01) and depression scores (t = 8.56, P < 0.01; t = 6.73, P < 0.01) were significantly higher in the intervention and non-intervention groups one day after PCI than one day after admission. At discharge from hospital, there were significant differences among the three groups in terms of anxiety and depression scores (P < 0.05), and the anxiety (t = 21.57, P < 0.01; t = 15.77, P < 0.01) and depression scores (t = 24.33, P < 0.01; t = 15.01, P < 0.01) were significantly higher in the intervention and non-intervention groups at discharge from hospital than one day after PCI, while the anxiety and depression scores were significantly lower among CHD patients in the intervention group than in the non-intervention group (P < 0.05). Conclusion The anxiety and depression are aggravated among CHD patients after PCI, and psychological interventions may alleviate the anxiety and depression.

HRP solution (33%) was injected into the left superior colliculus of 21 adult albino rats. 1-2 days after injection, the animal was sacrificed. Brains were frozen sectioned and processed according to. DAB- or TMB-method. The labeled neurones were examined in the right superior colliculus and other areas of the brain. The resu ts are as follows:1. No matter where the HRP was injected (either in the rostral or caudal part of the superior colliculus or thepart between them) HRP labeled neurones were always observed on the opposite superior colliculus if the injection sites reached layers deeper than the stratum oPticum. The locations of the labeled neurones corresponded roughly to the sites of HRP injections. However, no HRP labeled neurones were observed when the core of HRP deposites was restricted to layers superficial to the stratum griseum intermediale.2. Of all labeled neurones, 53.6% were located in the stratum griseum intermediale, 16.5% in the stratum opticum. The rest were in deeper layers. In no case were HRP labeled neurones observed in the stratum zonale or stratum griseum superficiale.3. Labeled neurones could be classified morphologically into vertical fusiform, horizontal fusiform and multipolar neurones.4. In addition to the visual cortex, labeled neurones were also found in the inferior colliculi, paralemniscal nuclei, dorsal nuclei of the lateral lemniscus, substantia nigrae and lateral tegmental nuclei bilaterally. Labeled neurones were also found in the ipsilateral ventral nucleus of the lateral geniculate body, contralatera pretectal area and reticular formation.

In order to investigate the distribution and other features of callosal neurons inthe visual areas,12 adult albino rats were used in a series of experiments,in whichHRP(30～50%,DAB brown reaction)was injected into one hemisphere and theretrograde labelled cells were observed in the other hemisphere.1.Hardly any labelled neuron was found in contralateral visual cortices whenthe injections were made at sites within 3.6 mm from the midline of the brain.However,when the injections were made at sites 4～6 mm from the midline,manylabelled neurons could be observed.2.Generally,most labelled cells aggregated near the border between area 17 and18a.In area 18a numerous cells were labelled,which distributed in the form ofincontinuous patches.In the proper of area 17,however,less labelled cells werefound.3.A gross topographical correlation was observed between locations of injectionand labelling on the two hemispheres.4.The labelled cells were found in all cortical layers except layer Ⅰ.In area 17they were mainly in layers Ⅳ and Ⅴ,while in area 18 a they were found mainly inlayers Ⅲ,Ⅳ and Ⅴ.5.Some callosal neurons were lightly labelled.For these cells,only the outlinesof the cell body could be seen even under dark-field microscope.The diameters ofthese cells were about 8～10?m.A few cells were as large as 16?m in diameter.Other labelled neurons could be seen with both dark-field and bright-field illumina-tions.They were identified as pyramidal,multipolar bipolar and granular cells accordingto the shape of the cell bodies and the pattern of dendrites.The majority of labelledcells were pyramidal cells,with a long apical dendrite to the pia surface,10～20?min diameter.Other ceils were 10～20?m for multipolar cells,and less than 10?m forgranular cells.Comparisons were made between the above results and the physiological studies.

Objective: To evaluate the effects of different interventions on adolescents’ Internet addiction and to clarify the optimal interventions, so as to provide a reference for intervention for adolesents’ Internet addiction. Methods: A randomized controlled trial of Internet addiction interventions in domestic and foreign databases such as Web of Science, PubMed, EMBASE, ProQuest, China Knowledge Network, Wanfang, and Weipu was conducted. The search time was built until November 29, 2019. The network Meta-analysis was performed using Stata 14.0.

AIM:To explore the effect of base curve aspheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism, and its influence on ocular surface morphology and tears.METHODS:A total of 232 adolescents(464 eyes)with myopia and moderate to high astigmatism treated in the hospital from December 2018 to March 2020 were selected as the research subjects. They were randomly divided into control group(116 patients, 232 eyes)and observation group(116 patients, 232 eyes). The control group was treated with base curve spheric orthokeratology lens, while the observation group was treated with base curve aspheric orthokeratology lens. Comparison was made between the two groups in terms of the correction effect, objective visual quality, ocular surface morphology, tears related indicators before and after wearing the lenses, and the incidence of complications after wearing the lenses for 12mo.RESULTS:After wearing the lenses, the uncorrected visual acuity(UCVA)and diopter of the two groups were significantly improved. The UCVA and diopter of the observation group were significantly better than those of the control group(all P<0.05). After wearing the lenses, the whole-eye and corneal coma, spherical aberrations and high-order aberrations were significantly increased, while Strehl ratio and modulation transfer function were decreased in the two groups. Trefoil aberrations was significantly increased(all P<0.05). These indicators in the observation group were better than those in the control group(all P<0.05). After wearing the lenses, the epithelium fluorescence staining scores, ocular surface disease index(OSDI)scores were significantly decreased in the two groups(P<0.05), but there was no statistically significant difference between the two groups(P>0.05); The noninvasive tear breakup time(NI-BUT)of the two groups were significantly decreased after wearing the lenses(P<0.05), but there was no statistically significant difference between the two groups(P>0.05). The Schirmer Ⅰ test and tear meniscus height of the two groups showed no statistically significant difference before and after wearing the lenses(P>0.05). The incidence rates of complications in the observation group and the control group after wearing the lenses were close(6.9% vs 6.0%, P >0.05).CONCLUSION:Base curve aspheric orthokeratology lens is superior to base curve spheric orthokeratology lens in the treatment of adolescents with myopia and moderate to high astigmatism in terms of correction effect and objective visual quality. The two lenses have similar influence on ocular surface morphology and tears.
