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 clinical manifestations and characteristics of tracheobronchial foreign bodies in children, and improve the diagnosis and treatment of foreign bodies.Methods:A retrospective analysis was performed on the clinical data of children with tracheobronchial foreign bodies confirmed by fiberoptic bronchoscopy between January 2010 to December 2019.The children with tracheobronchial foreign body who were treated in the Maternal and Child Health Hospital of Gansu Province.Results:A total of 967 cases were operated by soft electronic bronchoscope, and foreign bodies were removed by means of foreign body forceps or nets.Among them, 19 cases(3 cases with subglottic foreign bodies, one with row of pins, and the rest 15 cases with foreign bodies completely wrapped by granulation)were not removed, two cases were spontaneously coughed, and 946 cases (97.8%)were removed.Bronchial foreign bodies in children were more common in boys, with the ratio of male to female being 2.14∶1.The main age of onset was 1-3 years old(88.8%). The incidence was slightly higher in rural areas than that in urban areas(46.5% in urban areas, 53.5% in rural areas). Foreign bodies were inhaled most in March and least in June.From the perspective of season, winter and spring were more than summer and autumn.The foreign body types inhaled were mainly exogenous plant foreign body, accounting for 93.0%, among which peanut(31.7%)and melon seeds(19.2%)were the most common.The duration of foreign body inhalation was up to 347 cases(35.9%)in 1-3 days.There were 501 cases(51.8%)with endoscopic endobronchial inflammation, and 196 cases of children with varying degrees of granulomatous hyperplasia, accounting for 39.1% and 20.3% of the total.The foreign body in the right bronchus accounted for 50.0% and the left bronchus for 43.7%.There were 793 cases confirmed by imaging, with a positive rate of 81.9%, and 90.9% confirmed by CT.Conclusion:About 88.8% of tracheobronchial foreign bodies occurred in 1 to 3 years of age.The occurrence of foreign bodies had obvious gender, urban-rural and seasonal distribution characteristics, and more cases were male, in rural and winter as well as spring.
ABSTRACT
Objective To analyze the GDM of 336 cases with chronic HBV in pregnancy. Methods According to HBV DNA≥1.0 × 103 IU/mL, participants were divided into HBV DNA (+) or (-) group. 409 cases without HBV were selected as control group. Differences on GMD incidence between groups and virus load and OGTT blood sugar correlation were compared. Results The incidence of GDM of HBV DNA (+) or (-) group was 16.77% and 17.71%, which is higher than that in HBV group (10.27%). The difference is significant (P < 0.05). The correlation index between HBV DNA and fasting blood-glucose is r = 0.005, P = 0.610, the result of which is not statistically significant. But correlation index between HBV DNA and blood sugar at 1 h , 2 h are r = 0.082, 0.086; P = 0.000, 0.000, the result of which is statistically significant. Conclusion The oc-currence of GDM were higher in HBV DNA (+) or (-) group. The viral load is positively related with blood sugar of glucose tolerance at 1 h or 2 h.

The 3-year survival rate in the research group(71.43%) was significantly higher than 45.71% in the control group,there was significant difference(χ2 =11.70,P<0.05).Conclusion Neoadjuvant chemotherapy can reduce the expressions of MMP-2 and VEGF in tumor tissues,indicates that it may play an important role in patients with advanced gastric cancer and can be used in clinic.
ABSTRACT
An analytical procedure for the determination of water-and methanol-extractable pentachlorophenol ( PCP) in soils using vortex assisted liquid-liquid extraction ( VALLE ) and gas chromatography ( GC ) was developed. Significant extraction parameters, such as liquid-liquid ratio and vortex speed were optimized. The recovery of PCP was the highest ( 97. 4%) at the vortex rotation speed of 2000 r/min, with good reproducbility and a small relative sdandard deviation ( RSD, 0. 5%), with regard to the volume ratio of derivatization solution to n-hexane, the recovery of PCP was 103% with an RSD of 0. 7% at 10:4. The linearity of the calibration ranged from 1. 25 μg/L to 4000 μg/L, with a correlation coefficient ( R2 ) of 0. 9999. The detection limit of the PCP in water was below 0. 2 μg/L. Compared with traditional liquid-liquid extraction ( LLE) and solid phase extraction ( SPE) , the VALLE method was more simple and more economic in terms of chemical consumption, also with a recovery of 96. 8% and a RSD of 3. 7%. Four different soils were used to check the reliability of this method. The soils were respectively extracted with water once and methanol three times. The total recoveries were 89. 5%-98. 9% and 88. 7%-98. 4% at the PCP spiking level of 1 and 10 mg/kg, respectively. It is concluded that the VALLE method satisfied the extraction and determination of water and methanol extractable PCP in soils with varying PCP polluting rates.

ABSTRACT
Functions of the 3′untranslated regions (3′UTR) of eukaryotic mRNAs are complicated. They can control the stability and intracellular localization of mRNAs, and direct the translation of special amino acids. Mutations in the 3′UTR of some mRNA can cause serious diseases, and recent studies showed that the 3′UTR of some eukaryotic mRNAs possess tumor-suppression function.
