Allergic rhinitis （AR） is one of the most common chronic non-infectious inflammatory diseases in children. Traditional Chinese medicine （TCM） employs a comprehensive therapeutic system integrating treatment by stages and syndrome differentiation and treatment， demonstrating significant advantages in the management of pediatric AR. This article systematically reviews the clinical treatment methods and underlying mechanisms of TCM for pediatric AR in recent years. It is found that internal therapies （such as herbal formulas or Chinese patent medicines like Xiaoqinglong decoction， Yiqi tuomin decoction）， external therapies （including intradermal needles， acupoint application， tuina， and herbal nasal therapy）， as well as combined internal and external approaches （oral herbs combined with acupoint application）， have demonstrated significant effects in alleviating clinical symptoms， improving immune indicators， and reducing recurrence rates in children with AR. The underlying mechanisms are primarily associated with the regulation of signaling pathways such as Toll-like receptor/nuclear factor-kappa B and mitogen-activated protein kinase， thereby modulating immune balance， suppressing inflammatory responses， inhibiting pyroptosis， reducing mucus secretion， and promoting nasal mucosal repair.

Objective To explore the pneumoperitoneum signs of neonates on the bedside abdominal lying film.Methods The pneumoperitoneum signs of 52 neonates on the bedside abdominal lying films were analyzed retrospectively.Results Among 52 neonates with pneumoperitoneum,2 cases had no perforation,and there were 50 cases of digestive tract perforation,with 22 cases of gastric perforation,17 cases of small intestinal perforation and 11 cases of large intestinal perforation.Congenital muscular defect of gastric wall and necrotizing enterocolitis(NEC)were the most common causes of perforation.Forty-three cases with anteroposterior films all had pneumoperitoneum signs;and in 9 cases with anteroposterior and lateral films,6 cases with anteroposterior and lateral films all showed pneumoperitoneum signs,while 3 cases showed pneumoperitoneum signs only on lateral films.Pneumoperitoneum signs included 38 episodes of liver falciform ligament signs,37 episodes of football signs,22 episodes of Rigler signs,21 episodes of round liver ligament signs,10 episodes of liver area bright shadows,9 episodes of inverted"V"signs,6 episodes of scrotal gas,5 episodes of triangular signs,4 episodes of Cupola signs and 1 episodes of dolphin sign.Two or more signs were seen in 46 cases and three or more signs were seen in 31 cases.There was no statistically significant difference in the pneumoperitoneum signs except for scrotal gas among the three groups of gastric,small intestinal and large intestinal perforations(P>0.05).Conclusion Various signs such as liver falciform ligament signs,football signs,Rigler signs and round liver ligament signs can be seen on the bedside abdominal lying film for neonates pneumoperitoneum,and understanding the above signs is conducive to rapid and accurate diagnosis.

A novel technology is proposed for non-contact and real-time detection of atrial fibrillation using millimeter-wave radar.A 60 GHz PCR millimeter wave radar is used to continuously detect the chest echo signal of the subject.After signal acquisition,I-Q signal is generated through I-Q demodulation,and the signal phase information is extracted using effective points phase trend evaluation for obtaining the signals from oscillations in the chest wall,from which the respiratory signals and cardiac signals are extracted through digital filtering for the analysis of cardiac movement.Whether the atrial fibrillation occurs or not is determined by the characteristics of atrial fibrillation wave in the time domain.The effective points phase trend evaluation for extracting more accurate signal phase information and the time-domain method for real-time atrial fibrillation detection are the innovations of the study.The experimental results show that the proposed method achieves a detection accuracy of 99.2%in clinic.

Objective:To investigate the influence of combining therapy of massage on sacro-2 to sacro-4 spinal cord reflexion area and anal dilatation therapy on constipation after cerebral apoplexy and promote the rehabilitation of defecation function in patients with constipation after stroke.Methods:Aandomized controlled study method was chosen, 80 patients with constipation after cerebral apoplexy treated in Guangzhou Traditional Chinese Medicine Hospital from August 2018 to July 2019 were selected as research subjects by convenience sampling. The enrolled patients were divided into 2 groups, 40 to the observation group and 40 to the control group by random number table method. On the basis of routine constipation related nursing measures, the control group was given anal dilatation therapy, while the observation group′s treatment was given massage on sacro-2 to sacro-4 spinal cord reflexion area combined with anal dilatation therapy. Before intervention and after intervention, the changes of therapeutic effect of constipation effect, constipation symptoms scores and the degree of neurological deficit were all compared between the two groups.Results:There were 22 males and 18 females in the observation group; age ranged from 40 to 75 (63.33 ± 8.49) years old; in the control group, there were 23 males and 17 females, aged 41-74 (63.03 ± 7.60) years old. Before intervention, there was no statistically significant difference in constipation symptom scores and neurological deficits between the two groups (both P>0.05). After intervention, the score of constipation symptoms was (3.80 ± 2.05) points and the score of the degree of neurological deficit was (7.58 ± 2.69) points in the observation group, both lower than (5.18 ± 3.52) points and (8.90 ± 2.73) points in the control group with statistically significant differences between the two groups ( t values were respectively -2.13 and -2.19, both P<0.05). The total efficacy of the observation group was 97.50% (39/40), which was significantly higher than 87.50% (35/40) of the control group with statistically significant differences between the two groups ( χ2 = - 2.11, P<0.05). Conclusions:Nursing intervention of massage on sacro-2 to sacro-4 spinal cord reflexion area combined with anus dilatation therapy on constipation after cerebral apoplexy can effectively reduce the symptoms of constipation and lowered the degree of neurological deficit, which is beneficial to the functional rehabilitation of patients with cerebral apoplexy.

Background: Depression is a common clinical phenomenon in the patients with heart failure (HF). In traditional Chinese medicine (TCM), diseases in the brain and heart are thought to be correlated and interact. Naoxintong capsules (NXT) has been used for treating cardio-cerebrovascular diseases, while its therapeutic effect on depression after HF remains unclear. Objective: The aim of the study is to evaluate the intervention effect of NXT on depression after HF. Methods: Sprague-Dawley rats were assigned into the following 5 groups: sham, model, NXT (250, 1000 mg/kg), and valsartan (8 mg/kg). Coronary artery occlusion was performed to induce HF and subsequent depression in rats. The cardiac function was evaluated by echocardiography, hematoxylin-eosin staining, and Masson trichrome staining. The sucrose preference test and Morris water maze test were carried out to assess the depressive behaviors in rats. The ultrastructure of hippocampal CA1 neurons was observed and the levels of corticotropin-releasing hormone in the hypothalamus, brain-derived neurotrophic factor in the cortex, and adrenocorticotropic hormone (ACTH) in the plasma were determined by enzyme-linked immunosorbent assay. The levels of dopamine, 5-hydroxytryptamine, norepinephrine, and γ-aminobutyric acid in the hippocampus were measured by UPLC-QQQ-MS. Results: NXT reduced myocardial injury and pathological changes in the cardiac tissue and increased the left ventricular ejection fraction, left ventricular fractional shortening, and cardiac output. NXT increased the sugar preference rate and number of crossings and shortened the escape latency. Furthermore, the NXT treatment restored the levels of corticotropin-releasing hormone, adrenocorticotropic hormone, brain-derived neurotrophic factor, dopamine, and γ-aminobutyric acid to the baseline values. Conclusions: NXT not only demonstrates cardioprotective effect but also attenuates depression in the rats after HF. It may exert the antidepressant effect by inhibiting the hyperactivity of the hypothalamic-pituitary-adrenal axis and recovering the levels of neurotrophic factors and neurotransmitters.
