ABSTRACT
Objective:To investigate the efficacy of combination treatment with montelukast sodium, budesonide and formoterol in the treatment of bronchial asthma in adults and its effects on cytokines.Methods:A total of 100 adult patients with bronchial asthma who received treatment in The First People's Hospital of Yongkang from January 2019 to December 2020 were included in this study. They were randomly assigned to receive either budesonide inhalation alone (control group, n = 50) or combination inhalation of montelukast sodium, budesonide and formoterol (observation group, n = 50) for 12 weeks. Efficacy was compared between the two groups. Lung function [forced expiratory volume in one second (FEV 1), peak expiratory flow (PEF) and FEV 1/forced vital capacity (FVC) ratio], cytokines [interleukin (IL)-2, IL-4, IL-6], Asthma Quality of Life Questionnaire (AQLQ) score, and Asthma Control Test (ACT) score measured before and 12 weeks after treatment were compared between the two groups. Results:Total response rate in the observation group was significantly higher than that in the control group [92.00% (46/50) vs. 72.00% (36/50), χ2 = 6.77, P < 0.05). After 12 weeks of treatment, FEV 1, PEF and FEV1/FVC in the observation group were (2.17 ± 0.23) L, (246.56 ± 17.86) L/s, and (83.86 ± 3.98)%, respectively, which were significantly higher than (1.86 ± 0.17) L, (203.12 ± 20.10) L/s, (74.82 ± 5.67)% in the control group ( t = 7.66, 11.42, 9.22, P < 0.05). Serum IL-2 level in the observation group was significantly higher than that in the control group [(10.85 ± 0.86) ng/L vs. (8.94 ± 1.03) ng/L, t = 10.06, t < 0.05]. Serum IL-4 and IL-6 in the observation group were (24.98 ± 3.08) ng/L and (98.46 ± 9.76) μg/L, respectively, which were significantly lower than (36.75 ± 4.34) ng/L and (125.84 ± 13.19) μg/L in the control group ( t =15.63, 11.79, both P < 0.05). AQLQ score and ACT score in the observation group were (121.03 ± 8.69) points and (22.08 ± 1.35) points, respectively, which were significantly higher than (110.93 ± 7.86) points and (19.74 ± 1.76) points in the control group ( t = 6.095, 7.460, both P < 0.05). Conclusion:Inhalation therapy with montelukast sodium, budesonide and formoterol produces obvious therapeutic effects on bronchial asthma in adult patients and the combined therapy can reduce inflammatory reactions.

ABSTRACT
Objective:To investigate the effect of low expression of human epidermal growth factor-like domain protein 7 (EGFL7) gene in cervical cancer cell Hela on its migration and invasion ability.Methods:Cells in the experimental group used small interfering RNA (siRNA) to target the human EGFL7 gene to reduce the expression of EGFL7 in human cervical cancer cells Hela, and cells in the control group were transfected with Mock-siRNA. Real-time quantitative PCR was used to detect the EGFL7 mRNA content of cancer cells in each group; Western blot was used to detect EGFL7 protein expression of cancer cells in each group; The cell scratch healing experiment and Transwell experiment were used to detect the migration and invasion ability of Hela cells in each group.Results:siRNA reduced the protein expression of EGFL7 in human cervical cancer cell Hela. The wound closure percentage of Hela cells in the control group was 74.1%±6.8%. After the expression of EGFL7 was reduced, the percentage of cervical cancer cells was 42%±4.9%, and the wound closure ability was significantly reduced ( P<0.05) . The results of Transwell cell transfer showed that the number of cells successfully transferred by Hela cells in the control group was 179.24±20.01, while the number of cells successfully transferred by Hela cells with low EGFL7 expression was 79.22±13.16. The transfer ability of cells transfected with EGFL7-siRNA was significantly reduced ( P<0.05) . The results of invasion experiments showed that the number of successfully transferred cells in the control group was 79.35±8.04, the number of cells successfully transferred in the EGFL7-siRNA group was 26.98±6.24, and the invasion ability of Hela cells with low expression of EGFL7 decreased ( P< 0.05) . The expression of E-cad in Hela cells with low expression of EGFL7 was up-regulated, and the expression of MMP2/9 protein was down-regulated (all P<0.05) . Conclusion:The low expression of EGFL7 can reduce the migration and invasion ability of cervical cancer cell Hela through the EMT pathway.
ABSTRACT
Objective:To investigate the correlation between cognitive impairment and blood glucose, serum neuron specific enolase (NSE) and brain-derived neurotrophic factor (BDNF) levels after ischemic small-artery stroke.Methods:A total of 160 patients with ischemic small-artery stroke who received treatment in Jincheng People's Hospital from January 2018 to December 2019 were included in this study. They were divided into an observation group (with cognitive impairment, n = 68) and a control group (without cognitive impairment, n = 92) according to whether they had cognitive impairment. General data, blood glucose, NSE and BDNF levels were compared between the two groups. Multivariate logistic regression analysis was used to analyze the correlation between cognitive impairment and each factor after ischemic small-artery stroke. Results:There were no significant differences in gender, age, course of disease, body mass index, history of hypertension, hyperlipidemia, history of type 2 diabetes mellitus, history of smoking, and history of drinking between the two groups (all P > 0.05). The National Institute Health of Stroke Scale (NIHSS) score in the observation group was significantly higher than that in the control group [(18.86 ± 4.08) points vs. (14.27 ± 2.66) points, t = 6.664, P < 0.05], and the Mini-Mental State Examination (MMSE) score in the observation group was significantly lower than that in the control group [(21.45 ± 3.03) points vs. (24.28 ± 3.32) points, t = 4.452, P < 0.05]. There were no significant differences in glycosylated hemoglobin, fasting blood glucose, high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and total cholesterol levels between the two groups (all P > 0.05). There were significant differences in oxidized low-density lipoprotein (ox-LDL), NSE and BDNF levels between the two groups. The ox-LDL [(44.8 ± 7.6) mmol/L] and NSE [(26.5 ± 9.5) ng/mL] levels in the observation group were significantly higher than those in the control group [(35.9 ± 4.7) mmol/L, (11.6 ± 6.9) ng/mL, t = 7.04, 8.973, both P < 0.05]. BDNF level in the observation group was significantly lower than that in the control group [(5.1 ± 1.8) ng/mL vs. (6.3 ± 2.4) ng/mL, t = 2.828, P < 0.05]. Multivariate logistic regression analysis showed that ox-LDL and NSE levels and NIHSS score were independent risk factors of cognitive impairment after ischemic small-artery stroke (all P < 0.05), and BDNF level and MMSE score were independent protective factors (all P < 0.05). Conclusion:Cognitive impairment was correlated with NIHSS score, MMSE score, ox-LDL, NSE and BDNF levels in patients with ischemic small-artery stroke. ox-LDL and NSE levels as well as NIHSS score were independent risk factors and BDNF level and MMSE score were independent protective factors of ischemic small-artery stroke.

According to the type of circadian rhythm and sleep quality of nurses, nursing managers can take personalized measures to reduce their level of job burnout.
ABSTRACT
The three-dimensional (3D) conformation of chromatin is integral to the precise regulation of gene expression. The 3D genome and genomic variations in non-alcoholic fatty liver disease (NAFLD) are largely unknown, despite their key roles in cellular function and physiological processes. High-throughput chromosome conformation capture (Hi-C), Nanopore sequencing, and RNA-sequencing (RNA-seq) assays were performed on the liver of normal and NAFLD mice. A high-resolution 3D chromatin interaction map was generated to examine different 3D genome hierarchies including A/B compartments, topologically associated domains (TADs), and chromatin loops by Hi-C, and whole genome sequencing identifying structural variations (SVs) and copy number variations (CNVs) by Nanopore sequencing. We identified variations in thousands of regions across the genome with respect to 3D chromatin organization and genomic rearrangements, between normal and NAFLD mice, and revealed gene dysregulation frequently accompanied by these variations. Candidate target genes were identified in NAFLD, impacted by genetic rearrangements and spatial organization disruption. Our data provide a high-resolution 3D genome interaction resource for NAFLD investigations, revealed the relationship among genetic rearrangements, spatial organization disruption, and gene regulation, and identified candidate genes associated with these variations implicated in the pathogenesis of NAFLD. The newly findings offer insights into novel mechanisms of NAFLD pathogenesis and can provide a new conceptual framework for NAFLD therapy.
ABSTRACT
Objective@#To examine college students awareness of AIDS (acquired immunodeficiency syndrome) and HIV (human immunodeficiency virus), as well as their willingness to undergo testing, and to provide guidance for further education targeted towards AIDS prevention.@*Methods@#The respondents were selected from two companies of military training camps in 4 universities in Fengtai District of Beijing using cluster sampling, and a questionnaire was used to obtain relevant information among 1 248 college freshmen. The content of the questionnaire included basic information about the students, awareness of AIDS, and willingness to undergo testing.@*Results@#A total of 87.18% students were familiar with AIDS related knowledge, and 62.98% students intended to have HIV tests in the future. Willingness to be tested for HIV was higher among not local students (67.39%) than among local students(55.65%)(χ 2=17.32, P<0.05). The willingness to get HIV testing was higher among students who had an understanding of AIDS (65.26%) than among those who lacked an awareness(47.50%)(χ 2=18.87, P<0.05). In terms of the willingness to be tested for HIV, the main concerns focused on personal privacy (23.24%) and the cost (18.59%). Multivariate regression analysis showed that improving students awareness of five of the items related to a basic knowledge of AIDS may increase their willingness to get HIV testing(P<0.05). Most students indicated a preference to get HIV testing at a hospital (68.51%) or at the Centers for Disease Control and Prevention(42.79%).@*Conclusion@#The willingness to get HIV testing can be increased by launching an AIDS health education program that targets weak knowledge points with respect to AIDS awareness.
ABSTRACT
Objective:To investigate the effect of different solutions to prevent nasal intestinal blockage.Methods:Tottaly 199 cases of enteral nutrition treatment were selected from June 2018 to May 2019 and were randomly divided into three groups: warm boiled water group (67 cases), sugar-free cola group (67 cases), alpha-chymotrypsin group (65 cases). The rate of nasointestinal obstruction, the rate of nasointestinal obstruction, the rate of catheter patency maintenance, the rate of recanalization and the incidence of complications in three different enteral nutrition treatment cycles (< 7 days, 7-29 days, ≥ 30 days) were compared.Results:The catheter blockage rate in warm boiled water group was 20.9%(14/67) and in sugar-free cola group was 3.0%(2/67). The patency maintenance time in warm boiled water group was (8.83±1.84)days and in sugar-free cola group was (9.92±1.63) days ( t value was 2.182). The recanalization rate after blockage in warm boiled water group was 21.4%(3/14) and in sugar-free cola group was 100.0%( χ 2 value was 5.021, P < 0.05). The catheter blockage rate in sugar-free cola group was significantly lower than that in warm boiled water group, the catheter maintenance time and recanalization rate after blockage were significantly higher than that in warm boiled water group, the difference was significant ( P < 0.05). There was no significant difference between sugar-free cola group and alpha-chymotrypsin group in catheter blockage rate, catheter blockage rate, recanalization rate after blockage and incidence of complications( P > 0.05). The catheter blockage rate was 0 in patients with enteral nutrition treatment cycle < 7 days. The catheter blockage rate was 11.9%(8/67) (warm boiled water group) , 1.5%(8/67) (sugar-free cola group) and 1.5%(8/67) (alpha-chymotrypsin group) in patients with enteral nutrition treatment cycle 7-29 days. The catheter blockage rate was 9.0%(6/67) (warm boiled water group), 1.5%(1/65, sugar-free cola group) and 3.1%(2/67)(alpha-chymotrypsin group) in patients with enteral nutrition treatment cycle >30 days. The catheter blockage rate in sugar-free cola group and alpha-chymotrypsin group was significantly lower than that in warm boiled water group ( χ 2 values were 4.325-5.836, P<0.05) and there was no significant differences between the sugar-free cola group and the alpha-chymotrypsin group ( P>0.05). Conclusion:Sugar-free cola and alpha-chymotrypsin can effectively reduce the incidence of catheter blockage and complications, prolong the catheter patency and improve the recanalization rate after blockage, especially for patients with enteral nutrition treatment cycle longer than one week.
ABSTRACT
Objective:To investigate the effect of different plasticizers on the compressive strength of injectable calcium sulfate cement (ICSC).Methods:Hydroxymethylcellulose (CMC), methylcellulose (MC), hyaluronic acid (HA), stearic acid (SA) and self-made hemihydrate calcium sulfate were used to mix them, and the compressive strength of the complex was observed after reaction with normal saline; the changes of ICSC's own properties, such as setting time and injectability, were recorded.Results:The compressive strength of calcium sulfate was 21±4.58 mPa, and the final setting time was 3.86 ± 0.09 min. Different concentrations of SA had no significant effect on the compressive strength of calcium sulfate ( F=1.593, P=0.266), but prolonged the setting time ( F=29.868, P=0.000). CMC with different concentrations significantly reduced the compressive strength of calcium sulfate ( F=23.943, P=0.000), and the setting time was prolonged to more than 120 min. Different concentrations of MC can improve the compressive strength of calcium sulfate ( F=4.808, P=0.034), and prolong the setting time ( F=191.192, P=0.000); among them, 1% and 3% MC can significantly improve the compressive strength ( P=0.007, 0.027). Different concentrations of HA can improve the compressive strength ( F=3.818, P=0.058), and prolong the setting time ( F=262.515, P=0.000), of which 3% and 5% were significantly improved ( P=0.026, 0.015), while 1% group was not significantly improved ( P=0.062). In addition, the injectable properties of HA, MC, stearic acid and CMC are better, respectively. Conclusion:SA and CMC can not be used to improve the compressive strength of calcium sulfate, while HA and MC of appropriate concentration can improve the compressive strength of ICSC, and improve the injectable performance, but MC can make the coagulation time more in line with clinical needs.

Objective To explore the clinical characteristics of adults with functional articulation disorders (FADs) and suitable speech training methods.Methods Phonological evaluation was carried out for 37 adults with functional articulation disorders whose clinical characteristics were analyzed,then targeted speech training was established.Results The main erroneous articulation patterns of the adults were substitution,followed by distortion and omission.The erroneous articulation types included forward movement of the tongue (19 cases),insufficient aspiration (11 cases),lateralization (10 cases),backward movement of the tongue (7 cases),omission of consonants (7 cases),conprehensive errors (4 cases),and replacement by labiodental and lingua-palatal phonemes (3 and 2 cases respectively).Twenty-eight adults were cured,8 adults were improved,and 1 adult showed unsatisfactory effects after 1 to 5 courses of speech training.The average speech intelligibility score increased significantly from (56.03±14.71)％ before speech training to (91.22±10.10)％ afterward.Conclusion The main erroneous patterns of adults with functional articulation disorders are substitution and distortion.Targeted speech training was shown to be significantly effective.
