ABSTRACT
Objective: To investigate the sensitization characteristics of Juniperus chinensis pollen in patients with allergic rhinitis and/or allergic asthma in Beijing area, and to explore the characteristics of Juniper chinensis pollen sensitized population. Methods: Patients with suspected allergic rhinitis and/or asthma from January 2017 to December 2019 in the outpatient department of Allergy Department of Beijing Shijitan Hospital were selected in this study. Skin prick test (SPT) was performed with Juniper chinensis pollen allergen reagent to compare different age and disease allergen distribution, and to observe the sensitization characteristics of its population. All of the analyses were performed using SAS software version 9.4. Results: A total of 8 380 patients were enrolled in the end. The total positive rate of Juniper chinensis pollen SPT reached 49.92% (4 183/8 380). The positive rate of Juniper chinensis pollen SPT was highest in the 10-14 age group, reaching 60.99% (283/464). Compared with other age groups, there was a statistical difference (χ²=266.77, P<0.01). The SPT positive rate of patients aged less than 10 years increased with the increase of age, while the SPT positive rate of patients aged over 40 years decreased with the increase of age. Single Juniper chinensis pollen was less allergenic, accounting for about 25.05% (1 048/4 183), and the patients' age was (35.21±12.39) years. Regardless of single Juniper chinensis pollen or other pollen allergies, allergic rhinitis was the main disease. Among the patients with SPT positive Juniper chinensis pollen combined with other inhaled pollen allergens, willow pollen accounted for the first (74.99%). The positive rate of Juniper chinensis pollen was the highest in patients with single allergic rhinitis, accounting for 52.05% (3 797/7 295), and the rate in patients with single allergic asthma was the lowest, accounting for 17.49% (53/303), with statistically difference (χ²=138.99, P<0.01). Conclusions: Juniper chinensis pollen is highly sensitized in patients with allergic rhinitis and/or allergic asthma in Beijing . The positive rate of SPT is highest among 10-14 age group, most of which showed strong positive reaction, and allergic rhinitis is more common in Juniper chinensis pollen sensitization diseases.

Objective: To analyze the clinical characteristics of Chenopodiaceae pollen induced seasonal allergic rhinitis (SAR) as well as the distribution and sensitization characteristics of Chenopodiaceae pollen in Inner Mongolia grassland of northern China. Methods: From May 2015 to August 2015, using stratified, cluster and random sampling, a field interviewer-administered survey study and skin prick test (SPT) were conducted in six areas of Inner Mongolia grassland (Xilinhot, Erenhot, Duolun, Tongliao, Jarud, Kailu), and pollen monitoring was carried out in the above six areas from January 1 to December 31 of 2015. The clinical characteristics of Chenopodiaceae pollen induced SAR, distribution and sensitization characteristics of Chenopodiaceae pollen in these regions were observed. SAS software 9.4 was used for data processing. Results: A total of 6 043 subjects completed the study. The prevalence of Chenopodiaceae pollen induced SAR was 13.2% (795/6 043). The highest prevalence was found in the 18-39 age group. Subjects from urban areas showed higher prevalence of SAR than rural areas (61.2% vs 37.9%, P<0.001). There was significant regional difference in the prevalence rate of Chenopodiaceae pollen induced SAR among the above six areas (Xilinhot 21.5%, Erenhot 17.8%, Duolun 8.9%, Tongliao 6.9%, Jarud 15.3%, Kailu 9.7%, P<0.001). The main clinical symptoms of Chenopodiaceae pollen induced SAR were sneezing (96.5%) and nasal itching (92.2%). Eye itching was more obvious among the ocular symptoms (69.1%), while fatigue (32.1%) and drowsiness (31.5%) were more prominent among other related symptoms. Among comorbidities of Chenopodiaceae pollen induced SAR, allergic conjunctivitis accounted for 71.4% (568/795), food allergy accounted for 86.7% (689/795) and asthma accounted for 16.7% (133/795). The peak of Chenopodiaceae pollen spread was in August. The prevalence of Chenopodiaceae pollen induced SAR was positively correlated with the concentration of Chenopodiaceae pollen (R2=0.78, P=0.043). The SPT positive rate of Chenopodiaceae pollen was 21.2% (1 282/6 043), and Xilinhot had the highest rate in six regions (28.0%, 236/842). Conclusions: The prevalence of Chenopodiaceae pollen induced SAR in Inner Mongolia grassland stays at a high level. Sneezing is the most obvious symptom of SAR. The peak of Chenopodiaceae pollen spread is in August and the prevalence of Chenopodiaceae pollen induced SAR is positively correlated with the pollen concentration.

ABSTRACT
Walking is the embodiment of the ultimate goal of the central nervous system at the level of biomechanics, which is of great significance to the formation of children's psychological and motor independence. It is necessary to improve walking mobile function to obtain independent mobile ability and the quality of daily life. The standard of routine walking training cannot be unified, and the evaluation index cannot be standardized and quantified. Robot-assisted lower limb rehabilitation is the research hotspot in the field of improving walking mobile function in neurological dysfunction in recent years, which is characterized by high-intensity and repetitive locomotion. This paper briefly introduced the development, classification and rehabilitation mechanism of robot-assisted lower limb rehabilitation, and summarized the application of robot-assisted gait training in the rehabilitation of walking mobile dysfunction of children with spastic cerebral palsy based on the framework of International Classification of Functioning, Disability and Health. Robot-assisted lower limb rehabilitation can significantly improve the range of motion, muscle strength and spatiotemporal parameters of spastic cerebral palsy, and significantly improve the short-term motor and balance function. However, the researches on reducing abnormal muscle tone, reducing energy expenditure and improving participation ability are still controversial, and the standard of long-term efficacy and intervention measures still needs to be further studied. In the future, it is necessary to carry out multi-center research with large samples, so that the robot-assisted lower limb rehabilitation can be used as a supplementary mean of routine physical therapy for children with spastic cerebral palsy.
ABSTRACT
Objective:To investigate the effect of robotic-assisted gait training on the motor function and walking ability for children with spastic cerebral palsy. Methods:From October, 2020 to April, 2021, 34 children with spastic cerebral palsy were randomly divided into control group (n = 17) and experimental group (n = 17). The control group received conventional physical therapy 60 minutes a day, while the experimental group received physical therapy and robotic-assisted gait training, 30 minutes a day respectively. They were assessed with 10-meter walk test (10MWT), 6-minute walk distance (6MWD), Physiological Consumption Index, Gross Motor Functional Measure (D and E dimensions), center of pressure envelope area, and Functional Ambulation Categories before training, eight weeks after training, and one-month follow-up. Results:Four cases dropped out. All the indexes improved in the experimental group after training (|t| > 3.219, P < 0.05), and they were stable as follow-up (|t| < 1.565, P > 0.05), except 10MWT (|t| > 3.491, P < 0.01); while they were better than those in the control group (|t| > 2.108, P < 0.05), except 6MWD. Conclusion:Robotic-assisted gait training can promote the recovery of motor, balance and walking for children with spastic cerebral palsy based on conventional physical therapy, and remain at least one month.

ABSTRACT
Angelicae Sinensis Radix, with nourishing Yin, promoting blood circulation, and moisturizing dryness functions, is commonly used in clinical medicine. In order to investigate the effects and mechanism of Angelica sinensis(AS) on Th1/Th2 and Th17/Treg in mice with asthma and Yin deficiency syndrome, asthmatic and Yin deficiency syndrome Balb/c mice models were established by injecting and inhaling ovalbumin(OVA) and thyroxin. The models were treated with dexamethasone(DXM), AS extract and AS extract+DXM, respectively. Pathological examination of lung tissues was conducted by HE staining, and ELISA was used to detect the levels of IL-4, IL-17, IFN-γ, TGF-β as well as retinoic acid receptor-related orphan receptor (RORγt). Results showed that AS could significantly improve the situation of inflammation infiltration, increase ratios of IFN-γ/IL-4 and TGF-β/IL-17, decrease the levels of RORγt in lung tissues. The AS+DXM group showed a best treatment effect. The results indicated that AS played a therapeutic role for asthma with Yin deficiency syndrome and improved airway inflammation by inhibiting the expression of RORγt in lung tissues and regulating the balance of Th1/Th2 and Th17/Treg.
ABSTRACT
To explore the correlation between color of Glycyrrhiza uralensis and its quality evaluation,the colors of root bark and transverse section were determined by Precision Color Reader and Visual Analyzer,and the contents of six flavonoids and two saponins in G.uralensis were determined by high performance liquid chromatography（HPLC）.The partial least squares regression（PLSR）method was employed to correlate the colors with component contents in G.uralensis. The results showed that there were no significant differences in the colors of root bark but significant or very significant differences（P<0.05,P<0.01）in the colors of transverse section between the wild and cultivated G. uralensis. Compared with those in the cultivated G. uralensis, the contents of liquiritin, isoliquiritin isoliquiritigenin and the contents of ammonium glycyrrhizinate, glycyrrhetinic acid were obviously significant or remarkably significant in the wild G. uralensis.The correlation results showed that there was a significant or very significant correlation between the colors and the effective component contents. This study provides a scientific basis to evaluate the quality of G.uralensis by color and a new reference for the traditional evaluation methods for Chinese drugs.

ABSTRACT
To study the compatible mechanisms and compatible proportion of Shaoyao Gancao decoction, the intestinal absorption of main ingredients in Shaoyao Gancao decoction SG11 (Baishao-Zhigancao 1: 1) , SG31 (Baishao-Zhigancao 3: 1), Baishao water decoction S and Zhigancao (G) were investigated and compared using in vitro everted intestinal sac model and in situ single pass intestinal perfusion (SPIP) model. The concentration of paeoniflorin (PF), liquiritin (LQ) and mono-ammonium glycyrrhizinate (GL) in test samples and samples of intestinal sac and intestinal perfusion was determined by HPLC. The intestinal absorptive amount and absorption parameters were calculated. Results showed that in the everted intestinal sac model, three ingredients could be absorbed by duodenum, jejunum and ileum, and the absorption in the jejunum was best for all 3 ingredients. The absorption rate of three ingredients in SG11 was significantly higher than that in single decoction (P < 0.05), but had no significant difference compared with SG31. In SPIP model, the absorption rate constant K(a), the apparent absorption coefficient P(app) and the absorption rate of three ingredients in SG11 were significantly higher than those in single decoction. Parameters of PF and GL in SG11 were significantly higher than those in SG31, but had no differences of LQ. It proved that the compatibility of Baishao and Zhigancao could improve the intestinal absorption of PF, LQ and GL. The absorption of each ingredient in SG11 was better than that in SG31.

The therapeutic effect of acupuncture is closely related to acupoints, and the specificity of acupoint indications is one of the key factors for regulatory and therapeutic effects of acupuncture. In recent years, a number of researches focusing on acupoint specificity have been done through comparison of the effects of acupoint and non acupoint. In this article, by analysis of recent 10 years' comparative studies of acupoints and non-acupoints, main problems in the existing researches are put forward including laying stress on the study of local effects, belittling the study on general effect; confused selection of acupoints and non-acupoints; lack of high-quality multi-central, ran domized and controlled trials with large sample; and the train of thought of the future research are probed.
