RESUMEN
Objective:To explore the clinical effect of Pingchuan Decoction combined with routine western medicine therapy in the treatment of acute attack of bronchial asthma in children. Methods:From January 2017 to June 2019, 118 children with acute attack of bronchial asthma were selected from the Seventh People’s Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, and they were randomly divided into control group (59 cases) and observation group (59 cases) according to the random number table. The control group was treated with routine western medicine therapy, and the observation group was treated with Pingchuan Decoction on the base of control group, and both groups were treated for 14 days. The main symptom scores before and after treatment were evaluated. The percentage of forced vital capacity expressed as percent predicted (FVC% pred) and the forced expiratory volume in 1 second expressed as percent predicted (FEV1% pred) were measured by pulmonary function meter. The levels of CD3 +, CD4 + and CD4 +/CD8 + in peripheral blood were detected by flow cytometry. The adverse reactions during the treatment were recorded and the clinical efficacy was evaluated. Results:The total clinical effective rate was 93.2% (55/59) in the observation group and 71.2% (42/59) in the control group, where the difference between the two groups was statistically significant ( χ2=9.790, P=0.002). After treatment, the scores of cough, wheezing and wheezing rale in the observation group were significantly lower than those in the control group ( t=27.695, 17.573, 32.827, P<0.001). After treatment, FVC% pred [(80.21 ± 4.06)% vs. (71.71 ± 3.95)%, t=11.526], FEV1% pred [(78.84±3.92)% vs. (72.26 ± 3.59)%, t=9.508] in the observation group were significantly higher than those in the control group ( P<0.01). The levels of CD3 + [(74.05 ± 5.13)% vs. (67.44 ± 4.98)%, t=7.101], CD4 + [(48.43 ± 4.31)% vs. (42.20 ± 4.06)%, t=8.082] and the ratio of CD4 +/CD8 + (1.67 ± 0.29 vs. 1.34 ± 0.25, t=6.620) in the observation group were significantly higher than those in the control group ( P<0.01). During the treatment, the incidence of adverse reactions was 10.2% (6/59) in the observation group and 6.8% (4/59) in the control group, and there was no significant difference between the two groups ( χ2=0.437, P=0.509). Conclusion:The Pingchuan Decoction combined with routine western medicine therapy can reduce the clinical symptoms of children with acute attack of bronchial asthma, improve lung function, improve organism immunity and clinical effect with safety.
RESUMEN
Objective To investigate the clinical phenotype and molecular diagnosis of Noonan syndrome (NS) caused by mutations in SHOC2 gene. Methods The clinical data and gene testing results of one child with NS were analyzed retrospectively. Results This is an 8-month-old infant. Since birth, the boy had feeding and sleeping difficulties, irritability, and growth retardation. The boy had large head circumference, sparse, thin and yellow hair, broad and prominent forehead, flat nose, slightly wide eye distance, and slightly bilateral eye fissure outward tilt, no eyelid ptosis. Echocardiography showed patent foramen ovale,ventricular septum and left ventricular hypertrophy.A novel mutation(De novo)was found in the SHOC2 gene, heterozygous missense mutation c.4A>G, p.Ser2Gly His parents were normal genotypes. According to the clinical characteristics, relevant literature was reviewed. The clinical manifestation of sleep difficulty has not been reported in the NS patients with SHOC2 mutation.Conclusions This is the first domestic reported NS case with SHOC2 mutation.The phenotype is consistent with the foreign reports.Sleep difficulty may be a new phenotype of NS with SHOC2 mutation.
RESUMEN
Objective To identify the clinical risk factors of refractory Mycoplasma pneumoniae pneumonia (RMPP) and their values in early diagnosis. Methods The retrospective analysis of clinical data was conducted in 142 children with Myco-plasma pneumoniae pneumonia (MPP) admitted to Changhai Hospital of Second Military Medical University from Jan. 2012 to Jan. 2014. All children were divided into two groups, RMPP group (n=112) and MPP group (n=30). The comparison was made between two groups in clinical data. The factors were analyzed by the multifactor logistic regression. Results As compared to MPP, RMPP had longer fever duration, the higher ratios of large consolidation shadows, extrapulmonary complications and in-creased CRP level (P<0.05). The results of logistic regression indicated that the clinical risk factors included large consolidation shadows (OR=6.57, 95%CI:2.10-20.56), extrapulmonary complications (OR=11.66, 95%CI:2.42-56.08) and CRP (OR=14.87, 95%CI:2.67-82.79) (P<0.01). Conclusions Large consolidation shadows, extrapulmonary complications and CRP are clinical risk factors of RMPP. CRP elevation and lung imaging changes are valuable in early diagnosis of RMPP.
