ABSTRACT
Objective To investigate the effect of atractylenolideⅠon lung injury in rats with recurrent respiratory tract infection(RRTI)of lung and spleen qi deficiency by regulating phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin(PI3K/Akt/mTOR)pathway.Methods Eighty-four rats were randomly separated into a control group,a model group,a low-dose atractylenolideⅠgroup,a high-dose atractylenolideⅠgroup,a positive drug group,an insulin-like growth factor-1(IGF-1)group,and a high-dose atractylenolide Ⅰ+IGF-1 group,with 12 rats in each group.Except for the control group,the RRTI rat model of lung and spleen qi deficiency was constructed using a combination of fatigue,dietary disorders,and fumigation method with shavings and tobacco among rats in other groups.After the model is successfully copied,the model was administered once a day for 6 weeks.Animal lung function instrument was applied to detect the changes of peak expiratory flow(PEF),forced expiratory volume in first second(FEV1),forced vital capacity(FVC)in rats.The changes of wet/dry mass ratio of lungs in rats were detected.HE staining was applied to detect pathological changes of lung tissue in rats of each group.ELISA was applied to detect the levels of interleukin(IL)-6,tumor necrosis factor-α(TNF-α),malondialdehyde(MDA)and the activity of superoxide dismutase(SOD)in rat lung tissue.Western Blot was applied to determine the protein expressions of p-PI3K,p-Akt,and p-mTOR in rat lung tissue.Results Compared with the control group,rats in the model group showed a decrease in PEF,FEV1 and FVC(P＜0.01)and an increase in the wet/dry mass ratio of lungs(P＜0.01).The alveolar septa in lung tissues had become larger.Pulmonary interstitial edema and a large amount of inflammatory cell infiltration were found.The levels of IL-6,TNF-α and MDA in lung tissue increased(P＜0.01),and the SOD activity decreased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue increased(P＜0.01).Compared with the model group,rats in the low-,high-dose atractylenolideⅠgroups,and positive drug group showed an increase in PEF,FEV1,and FVC,and a decrease in the wet/dry mass ratio of lungs(P＜0.01).Pathologic damage in lung tissue was alleviated.The levels of IL-6,TNF-α,MDA decreased and SOD activity in lung tissue increased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue decreased(P＜0.01),while the corresponding indicators in the IGF-1 group showed opposite trends(P＜0.01).Compared with the high-dose group of atractylenolide I,rats in the high-dose atractylenolide I+IGF-1 group showed a decrease in PEF,FEV1 and FVC,and an increase in the wet/dry mass ratio of lungs(P＜0.01).Pathologic damage in lung tissue was increased.The levels of IL-6,TNF-α,MDA increased and the SOD activity in lung tissue decreased(P＜0.01).The protein expressions of p-PI3K,p-Akt,and p-mTOR in lung tissue increased(P＜0.05,P＜0.01).Conclusion AtractylenolideⅠmay improve lung injury in RRTI rats of lung and spleen qi deficiency by inhibiting the PI3K/Akt/mTOR pathway.
ABSTRACT
Objective To explore the clinical efficacy of ginseng schisandra decoction in children with lobar pneumonia(lung spleen deficiency syndrome)induced by mycoplasma pneumoniae infection and improvement of inflammatory indicators.Method 84 children with lobar pneumonia(lung spleen deficiency syndrome)caused by mycoplasma infection admitted to the First Clinical Hospital of Jilin Academy of Traditional Chinese Medicine from January 2020 to July 2022 were selected and randomly divided into two groups with 42 cases each.The conventional group was treated according to the traditional treatment plan,while the combined group was treated with ginseng and schisandra decoction in addition to the traditional treatment plan.After 7 days,compare the differences in traditional Chinese medicine syndrome scores,clinical efficacy,inflammatory indicators,and total incidence of adverse reactions between the two groups of children.Result The results showed that the traditional Chinese medicine syndrome score and inflammatory indicators in the combined group were lower than those in the conventional group(P<0.05),and the clinical efficacy level distribution was better than that in the conventional group(P<0.05).The total effective rate was higher than that in the conventional group(P<0.05),and there was no difference in the total incidence of adverse reactions between the two groups(P>0.05).Conclusion In the treatment of children with lobar pneumonia(lung spleen deficiency syndrome)caused by Mycoplasma pneumoniae infection,the modified Ginseng Wuweizi decoction has a positive therapeutic effect and good safety,and is worth promoting.
ABSTRACT
【Objective】 To investigate the effect of physical therapy combined with traditional Chinese medicine (TCM) in treating the syndrome of lung and spleen qi deficiency in children at asthma remission stage and the effect on serological indicators. 【Methods】 A total of 130 children with asthma in remission treated in our hospital from May 2018 to May 2020 were selected and randomly divided into combination group (n=65) and physical group (n=65). The physical group was treated with physical therapy and Montelukaste sodium chewable tablet, while the combination group was treated with Xiaoqinglong Decoction based on soil preparation and gold generation method. Both groups were treated for three months. The scores of chest tightness (attack), cough, asthma and laryngeal wheezing were compared between the two groups before and after treatment. The average score of TCM syndrome was recorded before treatment (T0), 1, 2 and 3 months after treatment (T1, T2 and T3), and 6 and 9 months after treatment (T4 and T5). Serum levels of interleukin 6 (IL-6), immunoglobulin (IgE) and tumor necrosis factor α(TNF-α) were detected before and after treatment. 【Results】 After treatment, the total effective rate in the combination group (86.15%) was higher than that in the physical group (73.85%) (χ2=4.333, P<0.05). After treatment, the TCM syndrome scores of asthma, laryngeal phlegm were significantly lower in the combination group than in the physical group (P<0.05). The average score of TCM syndrome in T3, T4 and T5 combination group was lower than that in the physical group (t=3.167, 3.317, 4.168, 4.267, P<0.05). After treatment, the levels of IL-6, IgE and TNF-α were decreased (P<0.05), and the levels of IgE and TNF-α in the combination group were lower than those in the physical group (t=12.164, 5.136, P<0.05). 【Conclusion】 Physical therapy combined with Xiaoqinglong Decoction can improve clinical symptoms and regulate immunity of children at asthma remission stage.
ABSTRACT
Objective::To observe the effect of Bimin decoction(BMD) on nuclear factor-kappa B(NF-κB) signaling pathway and aquaporin 5(AQP5) expression in allergic rhinitis (AR) rats with lung and spleen Qi deficiency syndrome(LSQDS), in order to study the mechanism in treating AR. Method::Fifty-six SD rats were randomly divided into seven groups: control group, AR group, LSQDS AR group, BMD low dose two weeks group and four weeks group, BMD high dose two weeks group and four weeks group. The control group did not intervened, the AR group established the AR disease model with ovalbumin (OVA) as the allergen, the other five groups established the LSDQS model with smoke and senna gavage, and also established the AR disease model with OVA sensitization at the same time as the AR group. After the model was established successfully, four BMD intervention groups were separately given low dose BMD (11.3 g·kg-1) for 2 weeks and 4 weeks, and high dose BMD (22.6 g·kg-1) for 2 weeks and 4 weeks. To observe the general situation of the rats, hematoxylin eosin (HE) staining was used to observe the pathological changes of the nasal mucosa, immunohistochemistry and Western blot were used to detect the expression levels of NF-κB and AQP5, real-time fluorescent quantitative polymerase chain reaction technique (Real-time PCR)was used to detect mRNA levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6). Result::The typical AR symptoms were found in AR rats, the AR symptoms and lung and spleen Qi deficiency symptoms were found in AR rats with LSQDS at the same time, and the AR symptoms and lung and spleen Qi deficiency symptoms were significantly improved after the intervention of BMD. Compared with the control group, the typical histopathological changes of nasal mucosa were found in AR group and LSQDS AR group, with a higher behavioral score (P<0.05), and the expression of NF-κB and AQP5 protein increased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA increased (P<0.05). Compared with AR group, the pathological changes of nasal mucosa in LSQDS AR group were more serious, and the expression of NF-κB protein in nucleus increased (P<0.05), the expression of TNF-α and AQP5 mRNA increased (P<0.05). Compared with LSQDS AR group, the pathological changes of nasal mucosa in the groups which interfered by BMD were improved, and the expression of NF-κB and AQP5 protein decreased (P<0.05), the expression of IL-1β, TNF-α, IL-6 and AQP5 mRNA decreased (P<0.05). Compared with BMD low-dose two-week group, the expression of NF-κB protein in nucleus decreased (P<0.05) in BMD high dose four week group. Conclusion::Compared with AR group, the AR condition of the rats with LSQDS is more serious under the same allergen stimulation, BMD can treat AR and reduce the over secretion of glands, which may be related to inhibit the expression of AQP5 by inhibiting the NF-κB signaling pathway.
