Childhood bronchial asthma （hereinafter referred to as asthma） is frequently accompanied by comorbidities such as allergic rhinitis， eczema， allergic enteritis， tic disorders， and obesity. Based on the theory of "syndrome-based disease regulation"， this paper proposes that dampness， heat， and phlegm constitute the common pathological basis of asthma comorbidities in children living in cold regions. Focusing on the remission stage of asthma， this paper proposes that treatment should emphasize dispersing and draining pathogenic factors， diffusing and unblocking sanjiao （三焦）， with clearing heat， draining dampness， and resolving phlegm as the fundamental therapeutic principle. For asthma complicated by allergic rhinitis， Xiebai Wendan Decoction （泻白温胆汤） combined with Cang'erzi Powder （苍耳子散） is recommended. For asthma complicated by eczema， Baiguo Wendan Decoction （白果温胆汤） combined with Yiyi Zhuye Powder （薏苡竹叶散） is applied. For asthma complicated by allergic enteritis， Zhizhu Wendan Decoction （枳术温胆汤） is selected. For asthma complicated by tic disorders， Changyu Wendan Decoction （菖郁温胆汤） is used. And for asthma complicated by obesity， Zexie Wendan Decoction （泽泻温胆汤） is prescribed. This approach aims to achieve the therapeutic goals of "treating different diseases with the same principle" and "regulating both constitution and disease".

Objective To explore the mechanism of Shen Hong capsule in preventing and treating acute mountain sickness based on biological information platform and in vitro experiment. Methods Traditional Chinese Medicine Systems Pharmacology （TCMSP） and Traditional Chinese Medicine Information Database （TCMID） were used to obtain the active components and predicted targets of Shen Hong capsule. Therapeutic Target Database （TTD）, Disease Gene Network （DisGeNET） database and GeneCards database were used to search for the targets of acute mountain sickness related diseases, and the potential therapeutic targets were obtained. The protein-protein interaction （PPI） was analyzed by Search Tool for the Retrieval of Interacting Genes/Proteins （STRING）, the Database for Annotation, Visualization, and Integrated Discovery （DAVID） online platform was used to analyse the Gene Ontology （GO） and the Kyoto Encyclopedia of Genes and Genomes （KEGG） signal pathway enrichment. The network information was visualized by Cytoscape software, the key targets in PPI network were obtained according to the topology data, and the binding ability of main active components and key therapeutic targets were analyzed by molecular docking. The validation of the main active components was performed by liquid chromatography-mass spectrometry （LC-MS）. The hypoxia model was created by H9c2 cells, apoptosis was visualized by Hoechst33342 staining, and key target proteins were verified by Western blot. Results 91 active components, 3 main active components and 150 predicted targets were selected from Shen Hong capsule. 515 targets of altitude sickness-related diseases and 37 targets of Shen Hong capsule regulating altitude sickness-related diseases were screened out. 44 related signal pathways, such as HIF-1 signal pathway, PPAR signal pathway, drug metabolism - cytochrome P450, were enriched and analyzed. TNF, IL1B, VEGFA, NOS3, EGFR, ESR1, PPARG, NR3C1, HMOX1 and IFNG were 10 key targets. The molecular docking results showed that the docking conformations between the main active components and the key targets were stable. The three main active components of quercetin, luteolin and kaempferol were identified by LC-MS, and in vitro experiments proved that Shen Hong capsule could relieve acute hypoxia injury by regulating the expression of HIF-1α, PPARG, NOS3, and TNF. Conclusion Shen Hong capsule could regulate the body’s hypoxia response and metabolism through multi-component, multi-target and multi-channel ways, so as to prevent and treat acute mountain sickness. This study provided a direction for further exploring the mechanism of Shen Hong capsule, and also provided a theoretical basis for further development and clinical application.

Cluster analysis （CA） was performed using the Microbioinformatics online analysis platform. Principal component analysis （PCA） and orthogonal partial least squares discriminant analysis （OPLS-DA） were performed using SIMCA 14.1 software. Random forest， extremely randomized trees， and extreme gradient boosting machine learning models were constructed using the SPSSAU online analysis platform. The comprehensive quality of the samples was evaluated by the entropy weight-technique for order preference by similarity to ideal solution （TOPSIS） method.RESULTS The contents of the above 12 components were 104.331-694.382， 652.217-1 085.075， 6.051-130.980， 612.174-1 417.179， 1.018-32.239， 0.953-24.967， 65.552-652.239， 2 019.412-5 385.807， 52.867-4 990.450， 156.307-883.180， 10.142-475.722， and 1 102.863-4 826.396 μg/g， respectively. The results of CA and PCA showed that the 18 batches of samples were divided into two categories： S1-S6， S10-S15 were grouped into one category， while S7-S9 and S16-S18 were grouped into another category. The OPLS-DA results showed that the variable importance in projection values of mesaconitine， glycyrrhizic acid， liquiritin， ellagic acid， hypaconitine， liquiritigenin， agarotetrol， gallic acid， and dehydrocostus lactone were greater than 1. The results of the three machine learning models showed that ellagic acid and hypaconitine had relatively large differential contributions. The entropy weight-TOPSIS results showed that the overall quality of samples from manufacturer B was superior to that of the other four manufacturers.CONCLUSIONS The established method is stable and feasible， and can be used to evaluate the quality of Zhachong-13 pills， in combination with multivariate statistical analysis. Ellagic acid and hypaconitine are differential markers that affect its quality.

Objectives:To investigate the clinical value of cardiac magnetic resonance imaging(CMR)feature-tracking strain analysis in risk stratification of diabetic heart failure with preserved ejection fraction(HFpEF).Methods:In this retrospective study,a total of 215 patients with diabetic HFpEF who underwent CMR at Chinese Academy of Medical Sciences Fuwai Hospital from January 2012 to December 2018 were included.Myocardial strain parameters were calculated using CMR feature-tracking technology.Patients were followed up by medical records or telephone calls.Composite endpoint event,all-cause death or heart failure hospitalization during follow-up were recorded.Patients were divided into event group and event-free group.Univariable and multivariable Cox proportional hazard regression analyses were performed to determine the risk factors for the outcomes in diabetic HFpEF.The effects of hypertension and obesity on the prognosis of diabetic HFpEF patients and whether they affect the prognostic value of CMR feature-tracking strain analysis were also analyzed.Results:During a follow-up of(7.1±1.8)years,93(43.3%)patients had endpoint events(event group),including 28 all-cause deaths and 65 heart failure hospitalization.Compared with the event-free group(n=122),patients in the event group had significantly lower left ventricular ejection fraction,higher prevalence and extent of late gadolinium enhancement,and significantly reduced global longitudinal strain(GLS),global circumferential strain,global radial strain,and global systolic longitudinal strain rate(all P<0.05).The absolute GLS value was significantly lower in event group than in event-free group,regardless of the presence of hypertension and obesity.Multivariate Cox regression analysis showed that estimated glomerular filtration rate(HR=0.983,95%CI:0.972-0.993,P=0.001),left atrial volume index(HR=1.015,95%CI:1.005-1.026,P=0.004),and GLS(HR=1.142,95%CI:1.060-1.231,P<0.001)were independent risk factors for adverse cardiovascular events in diabetic HFpEF patients.However,adjusted N-terminal pro-brain natriuretic peptide was not an independent prognostic factor.The cut-offvalue of GLS to predict outcome was-14.09%from ROC curve analysis.The Kaplan-Meier curve showed that in patients with and without hypertension and obesity,patients with the GLS>-14.09%had lower event-free survival compared to patients with GLS≤-14.09%(all P<0.05),and the ability of GLS to predict adverse outcomes was not affected by hypertension and obesity.Conclusions:GLS obtained by CMR feature-tracking strain analysis is an independent predictor of adverse outcomes in diabetic HFpEF,and its ability to predict adverse outcomes is independent of hypertension and obesity.

This article analyzed the clinical data of a patient with acute benzene poisoning caused by oral ingestion of 100 ml of pure benzene. The patient presented with multiple organ dysfunction syndrome, manifested as consciousness disorders, abnormal coagulation function with hematuria, and delayed liver injury. After comprehensive treatment including fluid replacement, diuresis, protection of vital organs, and nutritional support, the patient was discharged after recovery. Poisoning caused by oral administration of large doses of benzene is rare. Analyzing the diagnosis and treatment process of this patient can enhance clinicians' understanding of acute benzene poisoning, provide empirical references for the clinical treatment of such poisoning patients, and improve their survival rate as much as possible.

OBJECTIVE To study the anatomic characteristics of the anterior ethmoidal canal(AEC)based on 0.1 mm ultra-high resolution CT.METHODS Nine cadavers(18 side orbits)fixed in 10%buffered formalin were enrolled and underwent U-HRCT and MSCT.Divided AEC into horizontal,superior oblique,and inferior oblique segments and observed the displaying rate of each section.Subjective evaluation of display situation was performed by two experienced radiologists independently.The diameter of each AEC segment was measured.RESULTS No significant difference was found in the display rate of the horizontal and superior oblique segments between U-HRCT and MSCT groups(P>0.05),the display rate of inferior oblique segment of U-HRCT group was significantly higher than MSCT group(P<0.05).There was no significant difference in the objective evaluation results between two evaluators and consistency was strong.Subjective scores of each segment of AEC in U-HRCT group were 10.00 points(9.75 points,10.00 points),2.00 points(2.00 points,3.00 points)and 8.00 points(6.00 points,10.00 points),in MSCT group were7.00 points(5.75 points,8.00 points),2.00 points(2.00 points,2.00 points)and 2.00 points(2.00 points,4.00 points).Subjective scores of horizontal and inferior oblique segments of AEC in U-HRCT were higher than MSCT(P<0.05).The anteroposterior diameter of the horizontal section of AEC is(0.92±0.12)mm,the axial diameter is(1.04±0.22)mm.The anteroposterior diameter of the inferior oblique segment is(0.47±0.08)mm,and the transverse diameter is(0.50±0.06)mm.The anteroposterior diameter of the superior oblique segments is(0.66±0.11)mm,and the transverse diameter is(0.72±0.20)mm.CONCLUSION U-HRCT is better to evaluate AEC than MSCT.It could be used to help to study the anatomic characteristics of AEC before surgery to avoid complications.
