Objective To explore the therapeutic effects of Montelukast for bronchial asthma combined with allergic rhinitis(AR) in children.Methods Ninety asthmatic children with AR rhinitis were randomly divided into group A,group B and control group.The children in control group were treated only with Symbicort Turbuhaler.In addition to inhalation of Symbicort Turbuhaler,the children in group A were given Montelukast 5 mg/d orally,while the children in group B were given Budesonide Nasal Spray 64 ?g/d.All the children were observed for 6 months.Daytime and night asthma symptom scores,rhinitis symptom scores,the number of days with or without acute asthma symptoms were recorded every 4 weeks.FEV1%,as one of the lung function parameters,was also recorded in the pre-treatment and 8th week,24th week after the treatment.Results After the treatment,the daytime and night asthma symptom scores and rhinitis symptom scores of group A and group B were significantly reduced(group A:F=3.45,3.35 Pa0.05).However,there was better improvement of FEV1%,more days without symptoms and fewer acute asthma attacks in group A than those in group B (t=3.83,3.76,4.26 Pa

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

ObjectiveTo observe the influence of iodine on mRNA expression of iodide transporter (NIS),insulin-like growth factor Ⅰ (IGF- Ⅰ ) and transforming growth factor beta(TGF-β) in thyroid and mammary glands of lactating rats and to explore the role of NIS,IGF- Ⅰ and TGF-β mRNA in iodine uptake in thyroid and mammary glands of lactating rats.MethodsOne hundred and one Wistar rats(80 female and 21 male),weighting 8 - 100 g were selected.These female rats were randomly divided into five groups according to their body weight:control group(NI,normal feed,drank deionized water containing iodine 50 μg/L) ; low iodine group 1 and 2(LI-1,LI-2,low iodine feed,drank deionized water containing iodine 0 and 5 μg/L,respectively); high iodine group 1 and 2(HI-1,HI-2,normal feed,drank deionized water containing iodine 3000 and 10 000 μg/L,respectively),16 rats in each group.After feeding for 3 months,the female and male rates were mated 3:1.The female rats in each group were sacrificed at the fifth and tenth day after postpartum.Thyroid and mammary glands were taken.The mRNA levels of NIS,IGF- Ⅰ and TGF-β in thyroid and mammary glands of lactating rats were determined by real time quantitative PCR.ResultsThe fifth days after postartum,NIS,IGF- Ⅰ and TGF-β mRNA expression levels of thyroid and lactating mammary glands were different between groups,and the differences were statistically significant ( NIS:F =631.46,64.91,all P ＜ 0.01 ; IGF- Ⅰ:F =11.45,6.56,all P ＜ 0.01 ; TGF-β:F =291.83,304.53,all P ＜ 0.01).Compared with control group [NIS:0.0066 ± 0.0023, (0.1481 ± 0.0711 ) × 10-2; IGF- Ⅰ:0.0419 ± 0.0062,0.0542 ± 0.0044; TGF-β:0.1416 ± 0.0277,0.1670 ± 0.0499],regardless of thyroid or mammary gland,the NIS,IGF- Ⅰ and TGF-β mRNA expression of LI-1 [NIS:0.0447 ± 0.0110,(0.3030 ± 0.1831) × 10-2;IGF- Ⅰ:0.0662 ± 0.0078,0.0902 ± 0.008; IGF- Ⅰ:0.5514 ± 0.0508,0.6942 ± 0.0367],LI-2[NIS:0.0317 ±0.0081,(0.3017 ± 0.1601) × 10-2; IGF-I:0.0645 ± 0.0054,0.0894 ± 0.0093; TGF-β:0.5292 ± 0.0332,0.6704 ± 0.0277 ] was significantly increased (all P ＜ 0.01 ); the NIS mRNA expression of HI-1 [0.0043 ± 0.0011,(0.1233 ± 0.0954) × 10-2],HI-2[0.0037 ± 0.0017,(0.1058 ± 0.0854) × 10-2] was decreased(all P ＜ 0.05),while the expression of IGF-Ⅰ mRNA [0.0521 ± 0.0910,0.0715 ± 0.0026; 0.0516 ± 0.0078,0.0697 ± 0.0038] and TGF-β mRNA [0.2087 ± 0.0425,0.2361 ± 0.0425; 0.1971 ± 0.0237,0.2257 ± 0.0752 ] was increased (all P ＜ 0.05 ).The tenth days after postpartum,the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of thyroid and lactating mammary gland in rats were different between groups,and the differences were statistically significant (NIS:F =103.55,116.32,all P ＜ 0.01; IGF-Ⅰ:F =67.67,11.98,all P ＜ 0.01; TGF-β:F =74.30,381.30,all P ＜0.01 ).Compared with the control group[NIS:0.0069 ± 0.0011,(0.1337 ± 0.0599) × 10-2; IGF-Ⅰ:0.0390 ±0.0071,0.0534 ± 0.0056; TGF-β:0.1351 ± 0.0336,0.1534 ± 0.0320],the mRNA expression levels of NIS,IGF- Ⅰ and TGF-β of LI-1 [ NIS:0.0432 ± 0.0165,(0.2962 ± 0.0985 ) × 10-2; IGF- Ⅰ:0.0643 ± 0.0088,0.0873 ± 0.0055 ; TGF-β:0.5042 ± 0.0912,0.6408 ± 0.0420],LI-2[NIS:0.0287 ± 0.0111,(0.2873 ± 0.0862) × 10-2; IGF- Ⅰ:0.0621 ± 0.0094,0.0862 ± 0.0038; TGF-β:0.4893 ± 0.0504,0.6372 ± 0.0389] were significantly increased(all P ＜ 0.01 ); the NIS mRNA levels of HI-1 [ 0.0042 ± 0.0029,(0.1006 ± 0.0909) × 10-2],HI-2[0.0035 ± 0.0020,(0.0890 ± 0.0119) × 10-2] were decreased(all P＜ 0.05),while the expression of IGF-Ⅰ mRNA[0.0516 ± 0.0078,0.0668 ± 0.0071; 0.0508 ± 0.0089,0.0621 ± 0.0064] and TGF-β mRNA[0.2007 ± 0.0546,0.2175 ± 0.0370;0.1959 ± 0.0393,0.2097 ± 0.0425] were increased(all P ＜ 0.05 ).In thyroid and mammary glands,the comparisons of NIS,IGF,TGF-β mRNA expression of the fifth and tenth day after postartum,between each group were not statistically significant(all P ＜ 0.05).ConclusionsThere are regulatory mechanisms of thyroid and mammary glands of lactating rats in response to low or high iodine conditions.In low iodine,the expressions of NIS,IGF- Ⅰ and TGF-β mRNA in thyroid and mammary glands increase and iodide uptake ability is enhanced to meet the body needs.In high iodine,the expression of NIS mRNA decreases in thyroid and mammary glands.Due to the reduced ability of iodine uptake,iodine intake is reduced,thereby reducing the hazards of high iodine in filial rats.

The purpose of this study is to explore depression metabolic markers in rat hippocampus and to investigate the anti-depressant effect of genipin and its mechanisms using nuclear magnetic resonance (NMR) metabonomics. Chronic unpredictable mild stress (CUMS) procedure was conducted to establish the depressive rat model. At the beginning of the third week, genipin low dose (25 mg x kg(-1)), middle dose (50 mg x kg(-1)), high dose (100 mg x kg(-1)), and venlafaxine (50 mg x kg(-1)) were given to the CUMS rats separately once daily for two weeks except control and model groups. Rat hippocampus was analyzed by 1H NMR based metabonomics after drug administration for 2 weeks. Significant differences in the metabolic profile of rat hippocampus of the CUMS treated group and the control group were observed with metabolic effects of CUMS including decreasing in glycine and N-acetylaspartate, increasing in inositol, glutamate, lactate, glutamine, taurine and alanine. Genipin showed ideal antidepressive effects at a dose of 50 mg x kg(-1) in rats, decrease of inositol, glutamate, lactate, alanine were observed, while glycine and N-acetylaspartate were increased. Important influence has been found on normal nervous system function of these significant changed metabolites, which suggests that the antidepressant effect of genipin may be played by enhancing the activity of neurons in hippocampus, repairing and improving the function of the neuron. The metabonomics approach is an effective tool for the investigation of the anti-depressant effect and pharmacologic mechanisms of genipin.

OBJECTIVETo study the influence of neuro-psychological factors on the effect of acupuncture in the treatment of Bell's palsy and the overall prognosis in patients.

METHODSFifty patients with Bell's palsy were randomized into the treatment group and the control group, and they were treated with manipulated and non-manipulated acupuncture, respectively. Scorings by subjective perceptive scale of acupuncture, Cartel personality test, and Hamilton Anxiety Scale were performed and the curative effect was assessed according House-Brackmann grading standards.

RESULTSThe total effective rate of acupuncture was 78.0% (39/50), and that of manipulated acupuncture was better than that of non-manipulated acupuncture [89.2% (25/28) vs. 63.6% (14/22), P < 0.01]. Visual analogue scoring for perception of "Deqi", evaluated either by patients or by doctors, showed that the scores was higher in the treatment group than in the control group (P < 0.01). Cartel personality test (16PF) found that patients with personality factors of sociability, intellectuality, excitability, braveness, and independence were capable of getting "Deqi" more easily, there existed a significant correlation between personality factors and curative effect. By Hamilton Anxiety Scale scoring, 92.0% (46/50) of the patients were found being in an anxiety state, and the efficacy of treatment was negatively correlated with the degree of anxiety (r = -0.9491, P < 0.05).

CONCLUSIONNeuro-psychological factors put great influence on the efficacy of treatment for Bell's palsy, multiple measures, such as drug-therapy, acupuncture, psychological intervention, rehabilitation therapy, etc., should be taken in combination for improving patients' prognosis.

Objective:To investigate the incidence and risk factors of retinopathy of prematurity (ROP) in extremely preterm infants (EPI) before 28 weeks of gestation during 8-years period.Methods:A retrospective study. From January 1, 2011 to December 31, 2018, 300 EPI infants with a gestational age of less than 28 weeks admitted to the neonatal intensive care unit (NICU) of Tianjin Central Hospital of Gynecology Obstetrics were included in the study. EPI birth gestational week (GA), birth weight (BW), gender and other basic information, as well as neonatal respiratory distress syndrome, oxygen (≥10 d), bronchopulmonary dysplasia (BPD) and other hospitalizations and complications were recorded. According to ROP international classification standards, ROP was staged. Severe ROP was defined as ROP that requires treatment. The screening start time, screening interval, and intervention time of all children tested were carried out in accordance with the requirements of the "Guidelines for Screening Retinopathy of Prematurity" until the end of follow-up. The most severe ROP during the follow-up of each examined child was recorded as the final screening result of the examined child, and those with asymmetric eyes with the screening results of the severe side of the diseas was recorded. A retrospective analysis of the overall incidence of EPI ROP showed the incidence of severe ROP, and the first and second stages of EPI ROP during the 8 years (from January 1 , 2011 to December 31, 2014, and January 1, 2015 to December 31, 2018), changes in the rate of severe illness. Logistic regression analysis was used to screen independent risk factors for severe ROP.Results:Among 300 EPI infants, the average GA was (26.7±1.8) weeks; the average BW was (993.3±178.7) g. Two hundred and five infants (68.3%) were diagnosed with ROP, 116 (56.6%), 57 (27.8%), and 32 (15.6%) infants of stage Ⅰ, Ⅱ, and Ⅲ disease, respectively. There were no infants of stage IV and V. There were 30 infants (14.6%) with additional lesions and 59 infants (19.7%) with severe ROP requiring treatment. With the increase of GA ( χ2=52.391, 44.521; P=0.000, 0.000) and BW ( χ2=43.772, 26.138; P=0.000, 0.000), the incidence of EPI ROP and the incidence of severe ROP decreased significantly. From 2011 to 2018, the number of people surviving EPI obviously increased, especially those with small GA (26 weeks) and low BW (750 g). The average GA of the second stage EPI was lower than that of the first stage, the difference was statistically significant ( t=2.243, P=0.026); the average BW of the second stage EPI was lower than the first stage, the difference was not statistically significant ( t=1.428, P=0.154). The incidence of ROP in the second stage EPI was slightly higher than that in the first stage, and the incidence of severe ROP was lower than that in the first stage, the difference was not statistically significant ( χ2=1.069, 1.723; P=0.301, 0.189). Multivariate logistic regression analysis showed that GA<27 weeks ( β=-2.584, P=0.032), maternal chorioamnionitis (CA) ( β=-0.935, P=0.038) and BPD ( β=-1.432, P=0.001) was an independent risk factor for severe ROP. Conclusions:The incidence of EPI ROP and severe ROP are 68.3% and 19.7%, respectively. From 2011 to 2018, the number of survivors of EPI obviously increase, and those with small GA and low BW increase significantly; however, the incidence of ROP and severe ROP remaine stable. GA, CA and BPD are independent risk factors for severe ROP.

Nest polymerase chain reaction (PCR)was performed, and restriction endonudease digestion and gene fragments sequence were examined to detect the genotype of NOS24 G-954C.RESULTS: The genotypes of the sample population of 89 cases and 90 healthy controls were all detected as GG.CONCLUSION: The distribution of G-954C of NOS2A polymorphism are at a lower frequency in China, with little relevancy to the frequency of diabetic retinopathy combined with cystoid macular edema.

AIM: To better reveal the changing process of macula area after photodynamic therapy (PDT), the changes of tomographic imaging on macular fovea optical coherence tomography ( OCT ) scan at different follow- up time points after treating age-related macular degeneration ( AMD) by PDT were investigated.
METHODS: This cohort study included 30 eyes of 26 patients diagnosed as AMD. The dosage of verteporfin was calculated according to manufacturer's instruction. All participants got FFA, ICG, OCT scan and best corrected visual acuity before and followed up for 2wk, 1, 2, 3mo after PDT. The standard five lines combined with 6 lines OCT scan covered key parts of lesion and the scan locations before and after were kept the same. The bilaminar foveal thickness (BFT), outer high reflectivity band thickness ( OHRBT ) , and the total area of intraretinal fluid ( IRF ) and subretinal fluid ( SRF ) were measured at different time points. The relationship between the changes and follow up time was analyzed. Statistical analysis of the data was performed using SPSS for windows version 13. 0.
RESULTS: There months after treatment, an improvement of 2 lines or better on the Snellen chart was achieved on 22 eyes, visual acuity of 3 eyes without significant change, 3 eyes got decreased, 2 cases lost follow up. The average macular thickness of improved 22 eyes before treatment was 722. 5±55. 6μm, 2wk after treatment, 708. 3±45. 3μm, 1mo, 584. 4±49. 3μm, 2mo, 430. 7±50. 2μm and 180. 6 ±36. 3μm at 3mo. The OHRBT before and after treatment respectively were 302. 3 ±50-2μm, 277. 5±42. 3μm, 202. 7±40. 1μm, 180. 6±35. 7μm, 100. 8±22. 9μm. The total area of both IRF and SRF was estimated as 0. 34±0. 12mm2 , 0. 25±0. 07mm2 , 0. 10±0-05mm2 , 0. 08±0. 04mm2 , 0. 05±0. 01mm2 .
CONCLUSION:SRF and retinal edema of patients with AMD were absorbed 1mo after PDT, and the BFT, OHRBT were significantly tend to be thin.
