ObjectiveTo observe the clinical effectiveness and safety of Qingfei Shenshi Decoction （清肺渗湿汤） combined with western medicine for patients with bronchial asthma of heat wheezing syndrome， and to explore its potential mechanism of action. MethodsEighty-six participants with bronchial asthma of heat wheezing syndrome were randomly divided into treatment group and control group， each group with 43 participants. The control group received conventional western medicine， and the treatment group was additionally administered Qingfei Shenshi Decoction orally on the basis of the control group， 1 dose per day. Both groups were treated for 14 days. The primary outcome measure was clinical effectiveness； secondary outcome measures included traditional Chinese medicine （TCM） syndrome score， asthma control test （ACT） score， pulmonary function indices such as forced expiratory volume in 1 second （FEV₁）， forced vital capacity （FVC）， peak expiratory flow （PEF）， serum inflammatory factor levels including interleukin-4 （IL-4）， tumour necrosis factor-α （TNF-α）， and high-sensitivity C-reactive protein （hs-CRP）， and immune function indices including CD3⁺， CD4⁺， CD8⁺， CD4⁺/CD8⁺. All outcome measures were evaluated before and after treatment. Vital signs were monitored， and electrocardiography， blood routine， urine routine， liver function， and renal function tests were performed before and after treatment. Adverse events and reactions during the study were recorded. ResultsA total of 80 patients completed the trial with 40 in each group. The total clinical effective rate of the treatment group was 97.5% （39/40）， which was significantly higher than that of the control group （85.0%， 34/40， P＜0.05）. After treatment， both groups showed decreased TCM syndrome scores， IL-4， TNF-α， hs-CRP， and CD8⁺ levels， as well as increased ACT scores， CD3⁺， CD4⁺， CD4⁺/CD8⁺， FEV₁， FVC， and PEF levels （P＜0.05 or P＜0.01）. Moreover， the improvements in these indices were more significant in the treatment group than in the control group （P＜0.05 or P＜0.01）. No significant abnormalities in safety indicators were observed in either group， and no adverse events or reactions occurred. ConclusionQingfei Shenshi Decoction combined with conventional western medicine for patients with bronchial asthma of heat wheezing syndrome can effectively improve the clinical symptoms， pulmonary function， and clinical effectiveness， with good safety. Its mechanism may be related to reducing inflammatory factor levels and regulating T lymphocyte subsets to improve immune function.

This paper summarized Professor ZHOU Zhaoshan's clinical experience in treating bronchial asthma （abbreviated as asthma） by stages with dampness-draining method. It is believed that pathogenic dampness is the key pathological factor in the onset of asthma. Dampness accumulates into water， which gathers into rheum； the condensed rheum forms phlegm， which lingers in the lungs. When external pathogens trigger the latent phlegm， phlegm and qi become mutually obstructed， leading to airway obstruction， disrupted qi movement， and upward reversal of lung qi， thereby resulting in asthma attacks. The treatment emphasizes a stage-based approach. During acute attacks， the main syndromes include cold-damp obstructing the lungs， damp-heat accumulating in the lungs， and shaoyang （少阳） constraint with heat. For the syndrome of cold-damp obstructing the lungs， a self-formulated Wenfei Shenshi Decoction （温肺渗湿汤） is used to warm the lungs and disperse cold， drain dampness and relieve panting； for the syndrome of damp-heat accumulating in the lungs， a self-formulated Qingfei Shenshi Decoction （清肺渗湿汤） is employed to clear the lungs and expel heat， drain dampness and relieve asthma； and for the syndrome of shaoyang constraint with heat， a self-formulated Chaihu Shenshi Decoction （柴胡渗湿汤） is administered to harmonize the shaoyang， clear heat and drain dampness. During the remission stage， treatment is based on the underlying kidney-deficiency constitution， and a self-formulated Bushen Shenshi Decoction （补肾渗湿汤） is formulated to tonify the kidneys and drain dampness， improve qi reception and relieve panting.

Objectives:To explore the relationship between epicardial adipose tissue(EAT),left atrium and left atrial appendage(LAA)structures and LAA thrombosis in patients with non-valvular atrial fibrillation.Methods:Clinical data from non-valvular atrial fibrillation patients who underwent cardiac computed tomography angiography(CTA)and transesophageal echocardiography(TEE)at the Second Hospital of Hebei Medical University between November 2019 and October 2024,were retrospectively collected.Twenty-eight patients diagnosed with LAA thrombus by both CTA and TEE were enrolled as the LAA thrombus group(20 males,8 females,average age[65±9]years).Using an individual matching method,56 non-valvular atrial fibrillation patients without LAA thrombus,matched for gender and age(±3 years),were sequentially enrolled at a ratio of 1:2 as the no-thrombus group(40 males,16 females,average age[65±8]years).CTA was used to measure the epicardial adipose tissue volume(EATV),left atrial epicardial adipose tissue volume(LA-EATV),and structural parameters of the left atrium and LAA in both groups.The correlation between EAT,structural parameters of the left atrium/LAA and LAA thrombosis was evaluated.Results:In the LAA thrombus group,the proportions of patients with persistent atrial fibrillation and atrial fibrillation rhythm were significantly higher than in the no-thrombus group(both P<0.001).There were no statistically significant differences between the two groups in terms of age,gender composition,body mass index,duration of atrial fibrillation,and the proportions of patients with hypertension,diabetes,dyslipidemia,coronary heart disease,ischemic stroke,heart failure,vascular disease,and CHA2DS2-VASc scores(all P>0.05).Compared to the no-thrombus group,the EATV,LA-EATV,left atrial volume(LAV),LAA volume(LAAV),and LAA orifice area were significantly higher in the LAA thrombus group(all P<0.05).There was no significant difference between the two groups in the LAA depth(P=0.076).Conditional logistic regression analysis showed that LA-EATV(OR=1.092,95%CI:1.004-1.187,P=0.040)and LAV(OR=1.022,95%CI:1.003-1.041,P=0.025)were independent predictors of LAA thrombosis in non-valvular atrial fibrillation patients.The LA-EATV threshold for predicting LAA thrombosis was 27.16 cm3,with an area under the receiver operating characteristic curve(AUC)of 0.843(sensitivity 85.7%,specificity 76.8%);the LAV predictive threshold was 118.45 ml(AUC=0.853,sensitivity 82.1%,specificity 80.4%).Conclusions:LA-EATV and LAV measured by cardiac CTA are independent predictors of LAA thrombosis in patients with non-valvular atrial fibrillation.

Objective:To investigate the effects of early enteral and parenteral nutrition support on the growth, development, and metabolomics of low-birth-weight newborns.Methods:Ninety low-birth-weight newborns admitted to Hangzhou Maternity and Child Health Care Hospital from April 2022 to April 2024 were included in this retrospective study. They were randomly divided into a control group ( n = 45) and an intervention group ( n = 45) according to different intervention methods. The control group received routine traditional nutritional support, while the intervention group received early enteral and parenteral nutrition support. Data were collected on the growth and development status of the newborns, as well as their feeding conditions. Gastric fluid pH value, frequency of bowel sounds, and level of direct bilirubin were recorded. Physical condition was also assessed. The Neonatal Behavioral Neurological Assessment (NBNA) was used to evaluate the neurobehavioral status of the newborns. Additionally, the incidence of complications was recorded for both groups, and metabolomic changes were analyzed. Results:After intervention, the control group exhibited a time to regain birth weight of (20.67 ± 8.31) days, a time to reach a body weight of 2.0 kg of (53.57 ± 12.51) days, a lowest recorded body weight of (1.32 ± 0.21) kg, a body weight loss percentage of (12.31 ± 5.52)%, and a body weight gain of (15.02 ± 2.30) g/(kg/d). In contrast, the intervention group demonstrated a time to regain birth weight of (14.31 ± 5.62) days, a time to reach a body weight of 2.0 kg of (39.21 ± 9.32) days, a lowest recorded body weight of (1.01 ± 0.17) kg, a body weight loss percentage of (7.84 ± 4.92)%, and a body weight gain of (17.74 ± 3.94) g·kg?1·d?1. All differences between the two groups were statistically significant ( t = 4.28, 9.96, 7.69, 4.05, 4.11, all P < 0.001). The difference in the lowest body weight day between the two groups of children was not statistically significant ( P > 0.05). After intervention, the control group had an initial oral feeding duration of (8.30 ± 1.37) days, with a vomiting frequency of (10.25 ± 2.20) times, a daily milk intake of (35.38 ± 3.94) mL, a gastric fluid pH value of (3.85 ± 0.20), bowel sounds of (4.94 ± 0.97) times/minute, and a direct bilirubin level of (41.98 ± 25.76) mmol/L. In contrast, the intervention group showed an initial oral feeding duration of (4.01 ± 0.76) days, a vomiting frequency of (5.61 ± 1.24) times, a daily milk intake of (43.54 ± 4.07) mL, a gastric fluid pH value of (3.41 ± 0.12), bowel sounds of (5.86 ± 1.11) times/minute, and a direct bilirubin level of (28.98 ± 18.10) mmol/L. The differences between the two groups were statistically significant ( t = 18.36, 12.32, 9.66, 12.65, 4.18, 2.77, all P < 0.05). After intervention, the control group had a body length of (40.32 ± 1.84) cm, a body weight of (1.47 ± 0.55) kg, and a head circumference of (29.21 ± 1.07) cm. The intervention group had a body length of (45.00 ± 2.16) cm, a body weight of (1.83 ± 1.03) kg, and a head circumference of (30.14 ± 1.35) cm. The differences between the two groups were statistically significant ( t = 11.06, 2.06, 3.62, all P < 0.05). At 40 weeks of corrected gestational age post-intervention, the control group had a NBNA score of (30.11 ± 2.41), whereas the intervention group had an NBNA score of (34.52 ± 2.82). The difference between the two groups was statistically significant ( t = 7.97, P < 0.05). The number of patients experiencing common complications in the intervention group was lower than that in the control group [8 (17.78%) vs. 28 (62.22%), χ2 = 18.51, P < 0.05]. The control group had glycine levels of (94.07 ± 19.78) μmol/L, valine levels of (99.53 ± 13.42) μmol/L, homocysteine levels of (10.87 ± 4.43) μmol/L, cystatin levels of (233.71 ± 35.02) μmol/L, and methionine levels of (20.54 ± 4.67) μmol/L. The intervention group had glycine levels of (79.21 ± 17.54) μmol/L,valine levels of (88.70 ± 12.96) μmol/L, homocysteine levels of (13.68 ± 7.66) μmol/L, cystatin levels of (256.54 ± 35.49) μmol/L, and methionine levels of (22.97 ± 5.49) μmol/L. The differences between the two groups were statistically significant ( t = 3.77, 3.89, 2.13, 3.07, 2.26, all P < 0.05). Conclusions:Early enteral and parenteral nutritional support for low-birth-weight infants can restore their growth and development status, improve feeding conditions, enhance gastrointestinal function, and improve levels of metabolomic-related indicators.

Objective:To summarize the clinical phenotypes and genetic characteristics of Noonan syndrome-like disorder with loose anagen hair 2 (NSLH2) caused by PPP1CB variants. Methods:A case summary.Clinical data, laboratory findings, and imaging studies were collected from a patient with NSLH2 treated at Guangdong Women and Children Hospital in January 2024.Genomic DNA was extracted from the proband and his parents for whole-exome sequencing, with pathogenic variants verified by Sanger sequencing.Literature review was conducted to analyze clinical phenotypes, genetic features, and management approaches in NSLH2.Results:The patient manifested short stature, developmental delay, distinctive facial features, sparse eyebrows, slow hair growth, coarse hair texture, and hypotrichosis.Whole-exome sequencing identified a de novo heterozygous PPP1CB variant (c.146C>G, p.Pro49Arg).Literature review identified 26 reported cases (including this one), with cardinal features including developmental delay, impaired hair growth, abnormal hair texture, characteristic facies, congenital heart disease, short stature, and central nervous system abnormalities. Conclusions:NSLH2 is an autosomal dominant disorder caused by PPP1CB variants with characteristic manifestations.Genetic testing should be considered for children presenting with distinctive facies, developmental delay, impaired hair growth, and abnormal hair texture to establish a definitive diagnosis.

OBJECTIVE To explore the clinical characteristics of Mycoplasma pneumoniae pneumonia(MPP)after COVID-19 epidemic so as to offer help for early clinical diagnosis and treatment.METHODS The clinical data that were collected from the MPP patients who were treated in the fever clinic of the First Medical Center of Chinese PLA General Hospital from Jul.2023 to Aug.2024 were retrospectively analyzed.The results of laboratory tests for the different age groups of patients complicated with other pathogens were statistically analyzed.RESULTS Of totally 161 MPP patients who were enrolled in the study,78(48.85％)were male,and 83(51.55％)were fe-male;the average age was(32.98±14.35)years old,and the patients aged between 20 and 40 years old accoun-ted for 43.48％(70 cases).The enrolled patients were divided into the simple MPP group with 92(57.14％)ca-ses and the MPP+mixed group with 69(42.86％)cases according to the result of etiological test of sputum;the patients of MPP+mixed group were divided into the MPP+bacteria group with 42(60.87％)cases,the MPP+fungi group with 10(14.49％)cases,and the MPP+viruses group with 17(24.64％)cases.There was significant difference in the age among the groups(P＜0.05);there were no significant differences in the sex,white blood cell counts and percentage of mononuclear cells among the groups,the percentage of lymphocytes was highest in the simple MPP group,the levels of C-reactive protein(CRP)and interleukin-6(IL-6)were highest in the MPP+bacteria group,and there were significant differences(P＜0.05).All of the patients were divided into three groups:the ≤20-year-old group the＞20-40-year old group and the＞40-year-old group.There were no sig-nificant differences in the white blood cell counts,percentage of lymphocytes,percentage of mononuclear cells and IL-6 level among the three groups,and the CRP level was highest in the＞20-40-year old group(P=0.025).Ran-dom forest model analysis showed that the weight of CRP was highest(22.65％)among the clinical characteristics of the MPP patients,which played a key role in construction of model.As for other factors,the weight of age was 17.02％,the percentage of lymphocytes 15.34％,the white blood cells counts 14.86％,the percentage of mono-nuclear cells 14.39％,the IL-6 13.61％,the gender 2.13％.CONCLUSION MPP maintains common among the patients aged less than 40 years old after the COVID-19 epidemic,nearly half of the patients are complicated with the infections of other pathogens,and CRP is more helpful for the clinical diagnosis and treatment of the MPP in early stage.
