ABSTRACT
Objective:Data mining technology was used to analyze the regulation of food therapy prescriptions in treating children′s stagnation.Methods:Collect the therapy prescriptions used for regulating children's stagnation in the Dictionary of Traditional Chinese Medicine Prescriptions, the Complete Record of Dietary Therapy Prescriptions of Traditional Chinese Medicine and the Dictionary of Chinese Medicinal Diet, extract the information of prescription name, composition, etc, and use SPSS 22.0 for frequency analysis, and use Weka for correlation analysis. Results:A total of 99 dietary prescriptions for children with hysteria were included, involving a total of 62 foods, with a total use frequency of 224 times, among which the food with high use frequency were chicken gizzard, japonica rice, hawthorn, etc. The four characteristics of food were mainly concentrated in the flat, the five tastes were mainly concentrated in the sweet, the return channel was mainly concentrated in the spleen and stomach channel, and the effect was mainly concentrated in the absorption of food and tonic deficiency. The main symptoms of the therapeutic prescription for children's accumulation of stagnation were internal accumulation of milk and food and combination of spleen deficiency. The commonly used food combination for children's accumulation of stagnation of milk and food was "fructus amomi - chicken gizzard". The commonly used food combination of children with spleen deficiency and accumulation of stagnation was "lentil bean-yam-japonica rice" and "millet-yam".Conclusions:Traditional Chinese medicine diet prescription for the treatment of children's accumulation of stagnation pay attention to harmony and regulation, sweet and slow tonifying, emphasizing the adjustment of the spleen and stomach, taking into account the regulation of lung, following the "eliminating and supplementing both, according to the cause of treatment" rule, advocate syndrome differentiation of food.
ABSTRACT
Objective:To explore the influence of airway mucus plugs on patients with bronchial asthma and its management.Methods:In this cross-sectional study, from January 2020 to June 2022, 100 patients who were diagnosed with asthma and underwent chest CT examination in the Outpatient Department of Peking University Third Hospital were included. The chest CT results and medical history, pulmonary function, fractional exhaled nitric oxide (FeNO), blood routine, total allergen IgE, Aspergillus fumigatus M3 allergen-specific IgE antibody test results were collected. According to the results of chest CT, the asthma patients were divided into group with mucus plugs and those without mucus plugs. Distribution of airway mucus plugs and the mucus plug scores based on lung segments were calculated. The relationships of mucus plugs with medical history, pulmonary function [These included before and after the bronchodilation test, forced vital capacity percent of predicted value (FVC%pred), forced expiratory volume in one second percent of predicted value (FEV 1%pred), FEV 1/FVC, peak expiratory flow percent of predicted value (PEF%pred), maximal mid-expiratory flow percent of predicted value (MMEF%pred), maximal expiratory flow at 25%, 50%, 75% of vital capacity remaining percent of predicted value (MEF 25%pred, MEF 50%pred, MEF 75%pred)], FeNO, and peripheral blood eosinophil (Eos) counts were analyzed. The logistic regression model was used to analyze whether airway mucus plug was a risk factor for asthma exacerbation, and the corresponding intervention strategies were explored. Results:Among the 100 patients with asthma, 24 cases were in the mucus plug group and 76 cases were in the non-mucus plug group. The distribution of mucus plug was more common in the lower lungs (30.53% and 9.16% in the lower and upper lobe of left lung, respectively; 29.01%, 14.50% and 16.80% in the lower, middle and upper lobe of right lung, respectively). The average score of mucus plug was (4.42±3.12) points. The body mass index (BMI), the number of visits to a doctor due to asthma exacerbations, FeNO, peripheral blood Eos counts in the mucus plug group were higher than those in the non-mucus plug group [(24.95±4.34) vs (23.22±2.91) kg/m 2, 0(0, 1) vs 0(0, 0), 97(37, 169) vs 31(18, 59) ppb (1 ppb=1×10 -9), 0.41(0.15, 0.70) vs 0.18(0.09, 0.37)×10 9/L](all P<0.05), and FVC%pred, FEV 1%pred, FEV 1/FVC, PEF%pred, MEF 50%pred, MEF 25%pred, MMEF%pred, MEF 75%pred were lower than those in the non-mucus plug group [(87.49±19.32)% vs (97.34±14.24)%, (76.49±19.58)% vs (91.07±18.33)%, (72.44±10.91)% vs (79.48±8.13)%, (82.36±24.46)% vs (93.83±18.27)%, (53.03±24.81)% vs (75.75±27.15)%, (46.47±22.92)% vs (64.09±25.90)%, (50.28±23.73)% vs (74.53±26.80)%, (71.30±27.55)% vs (89.92±26.82)%] (all P<0.05). In the group with mucus plug, the airway mucus plug score was positively correlated with the patient′s body weight and the number of peripheral blood Eos counts at enrollment ( r=0.413, 0.478; all P<0.05), and negatively correlated with FVC%pred and FEV 1%pred ( r=-0.576, -0.465; all P<0.05). Logistic regression analysis showed that airway mucus plug score was a risk factor for acute asthma attack ( OR=1.269, 95% CI: 1.031-1.562; P=0.024). Conclusions:Asthma patients have a high incidence of airway mucus plug, which is related to the level of Eos inflammation and body size. Airway mucus plugs can promote airflow obstruction and acute exacerbation of asthma. In clinical practice, appropriate asthma management policies can be formulated for airway mucus plugs to delay the progression of asthma and reduce the number of acute attacks.
ABSTRACT
Objective:To analyze the clinical characteristics and short-term prognosis of patients with acute asthmatic attack and comorbid bronchiectasis.Methods:The data of patients hospitalized for acute asthmatic attack in the Department of Respiratory and Critical Care Medicine of Peking University Third Hospital from January 1, 2012 to December 31, 2021 were retrospectively collected and analyzed. According to whether or not co-existing with bronchiectasis, all the patients were divided into asthmatic with bronchiectasis group and asthmatic without bronchiectasis group. Then the general conditions, comorbidities, pulmonary function test, grades of asthma severity, laboratory examination and in-hospital short-term prognosis of two groups were analyzed.Results:A total of 580 hospitalized patients with acute asthma attack were included, of which 132 cases (22.76%) were classified into asthmatic with bronchiectasis group and 448 cases (77.24%) were classified into asthmatic without bronchiectasis group. Co-existing with obsolete pulmonary tuberculosis and anxiety/depression in asthmatic with bronchiectasis group were more common than that in asthmatic without bronchiectasis group (13.64% vs 5.36%; 7.58% vs 2.68%) (both P<0.05). The pre-bronchodilator forced vital capacity (FVC) and its percentage to the predicted value (FVC%pred), forced expiratory volume in 1 second (FEV 1) and its percentage to the predicted value (FEV 1%pred), FEV 1/FVC and post-bronchodilator FEV 1 in asthmatic with bronchiectasis group were lower than those in the asthmatic without bronchiectasis group [2.44 (1.90, 3.01) vs 2.69 (2.10, 3.68) L, 1.55 (1.13, 2.00) vs 1.78 (1.25, 2.52) L, 70.14% (67.39%, 85.92%) vs 79.63% (70.00%, 89.52%), 70.00% (54.38%, 78.11%) vs 70.00% (61.47%, 85.00%), 61.57% (56.29%, 73.03%) vs 66.67% (60.00%, 75.00%), 1.72 (1.21, 2.18) vs 1.89 (1.37, 2.55) L] (all P<0.05). In previous year, the proportion of patients receiving hospitalization due to acute asthmatic attack in asthmatic with bronchiectasis group was higher than that in asthmatic without bronchiectasis group (15.15% vs 8.93%) ( P<0.05). The peak months of hospitalization due to acute asthmatic attack in asthmatic with bronchiectasis group were April, July and October, and the peak months in asthmatic without bronchiectasis group were April and September. The length of hospital stay was longer and the proportion of patients receiving invasive ventilation was higher in asthmatic with bronchiectasis group than those in asthmatic without bronchiectasis group [10.06 (7.62, 13.94) vs 9.95 (7.15, 13.76) d; 5.30% vs 2.01%] (both P<0.05). The risk factors for invasive mechanical ventilation in asthmatic patients with acute attack during hospitalization were co-existing with bronchiectasis, smoking, high level of partial pressure of carbon dioxide in arterial blood, serum creatinine and creatine kinase. Conclusion:Asthma patients with comorbid bronchiectasis have more frequent acute attack, a longer hospitalization due to acute asthmatic attack and a higher probability of invasive ventilation during hospitalization.
ABSTRACT
OBJECTIVE:To provide reference and basis for strengthening the drug quality supervision of medical institutions.METHODS:The problems about the drug quality supervision of the medical institutions were analyzed from the angle of legislation.Countermeasures for strengthening drug quality supervision of medical institutions in China as well as legislative suggestions on improving drug quality supervision of medical institutions in China were put forward.RESULTS & CONCLUSIONS:At present,the existing problems about drug quality supervision in medical institutions include that pharmacy setting lack mandatory standards;routine drug quality supervision is mainly the formal regulation;the punishment of drug related illegal behavior in medical institutions is too light,etc.To strengthen drug quality supervision of medical institutions in China,it is suggested that the government should establish the mandatory standards for medical institution pharmacy setting,add administrative inspections,and formulate Good Using Practice applicable to the whole country.When perfecting the law of drug quality supervision in medical institutions in China,relevant provisions may be added in The Drug Administration Law of the PRC,Regulations for the Implementation of Drug Administration Law,and the subordinate laws and regulations of Management Regulation of Medical Institutions so as to strengthen drug quality supervision of medical institutions.
