Objective To investigate the correlation between the clinical characteristics of allergic rhinitis(AR)in adults located in Shenzhen area and the traditional Chinese medicine(TCM)constitutions.Methods A cross-sectional survey of adult AR patients in Shenzhen was conducted.From June 2022 to December 2023,adult AR patients admitted to the Department of Otolaryngology outpatient clinic of Bao'an Traditional Chinese Medicine Hospital Affiliated to Guangzhou University of Chinese Medicine(Shenzhen Bao'an District Hospital of Traditional Chinese Medicine)were selected as the study subjects.The clinical baseline data,Total Nasal Symptoms Score(TNSS),and Total Non-Nasal Symptoms Score(TNNSS)of the patients were collected for the analysis of clinical characteristics,and TCM constitutions were differentiated based on the information collected by TCM constitutions questionnaire.After that,the correlation between the biased TCM constitutions and clinical characteristics were explored by using analysis of variance,non-parametric test and Logistic regression analysis.Results(1)A total of 215 cases of adult AR patients from Shenzhen were included.Most of the patients were male(60.93％),and the patients were usually aged 18-29 years old(accounting for 48.84％).AR in adults often arose in the spring(33.49％)and fall(30.70％).(2)Lung qi deficiency-cold syndrome was the predominated TCM syndrome type of AR in adults,accounting for 40.93％,and then came kidney yang deficiency syndrome(26.98％),spleen qi deficiency syndrome(20.00％),and heat accumulation in lung meridian syndrome(12.09％).Lung qi deficiency-cold syndrome and heat accumulation in lung meridian syndrome were more common in young males,and kidney yang deficiency syndrome was frequently seen in middle-aged and elderly males.(3)The leading three TCM constitution types of AR in adults were qi deficiency constitution(30.23％),yang deficiency constitution(24.65％),and inherited special constitution(15.81％).In adult AR patients with lung qi deficiency-cold syndrome,the commonly-seen TCM constitution types were qi deficiency constitution,inherited special constitution,and balanced constitution.In adult AR patients with spleen qi deficiency syndrome,the commonly-seen TCM constitution types were inherited special constitution,phlegm-damp constitution,and yang deficiency constitution.In adult AR patients with kidney yang deficiency syndrome,the commonly-seen TCM constitution types were yang deficiency constitution,qi stagnation constitution,and inherited special constitution.In adult AR patients with heat accumulation in lung meridian syndrome,the commonly-seen TCM constitution types were damp-heat constitution,yin deficiency constitution,and blood-stasis constitution.The leading five TNSS scores were shown in adult AR patients with inherited special constitution,qi deficiency constitution,yang deficiency constitution,phlegm-damp constitution,and qi stagnation constitution,respectively.And the leading five TNNSS scores were shown in adult AR patients with yang deficiency constitution,inherited special constitution,qi stagnation constitution,yin deficiency constitution,and damp-heat constitution,respectively.(4)The results of statistical analysis showed that the differences in gender among the adult AR patients with various TCM constitution types were not statistically significant(P＞0.05),but the differences in age groups,TCM syndrome types,TNSS scores and TNNSS scores were statistically significant(P＜0.01 or P＜0.001).(5)The results of Logistic regression analysis showed that the TNSS scores and TNNSS scores were all positively correlated with qi deficiency constitution,yang deficiency constitution,and inherited special constitution,and spleen qi deficiency syndrome was negatively correlated with damp-heat constitution,the differences being all statistically significant(P＜0.01 or P＜0.001).Conclusion The onset of AR in adults from Shenzhen area is closely related to age,gender,season,and TCM constitutions.The adult AR patients usually have the biased constitutions,in particular qi deficiency constitution,yang deficiency constitution,and inherited special constitution.In adult AR patients,higher TNSS scores are correlated with inherited special constitution,higher TNNSS scores are correlated with yang deficiency constitution,and the primary TCM syndrome type of lung qi deficiency-cold syndrome is correlated with qi deficiency constitution.

Sacroiliac complex injuries are commonly seen in high-energy pelvic fractures. The injuries make a big difference in treatment patterns due to the diverse injury types, posing considerable challenges in formulating optimal treatment strategies, and hence are persistent clinical difficulties in orthopedic trauma. The clinical management of sacroiliac complex injuries presents several key challenges such as a non-negligible rate of missed diagnoses in associated vascular and visceral injuries, absence of standardized protocols for surgical approaches and reduction-fixation strategies across different injury patterns, and ongoing controversies regarding surgical indications and optimal timing for patients combined with concomitant lumbosacral plexus injuries. Currently, no systematic clinical guidelines are available for the diagnosis and treatment of sacroiliac complex injuries both domestically and internationally. To this end, the Pelvic and Acetabular Surgery Group, Orthopedic Branch, China International Exchange and Promotive Association for Medical and Health Care and Orthopedic Physician Branch, Chinese Medical Doctor Association organized a panel of domestic experts in the field to develop the Clinical guideline for the diagnosis and treatment of sacroiliac complex injuries ( version 2025), based on evidence-based medicine and adhering to the principles of scientific rigor, clinical applicability, and innovation. These guidelines provided 11 recommendations covering diagnosis, therapeutic principles and techniques, management protocols for lumbosacral plexus injuries, outcome evaluation, and postoperative rehabilitation pathways, etc., aiming to standardize the clinical management of sacroiliac complex injuries.

Objective:To investigate the value of ultra micro angiography（UMA）imaging in evaluating the inflammation activity of pediatric Crohn's disease（CD）patients.Methods:In this prospective study，71 pediatric CD patients confirmed by clinical symptoms，laboratory and ileocolonoscopical results who planed to accept infliximab injection treatments in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine from April to December 2024 were included. The CD patients were included and divided into 3 groups according to the pediatric Crohn's disease activity index（PCDAI）score：inactive CD group（ n=44），mild CD group（ n=17），and moderate-to-severe CD group（ n=10）. Before treatment，pediatric CD patients underwent B mode ultrasound（BMUS），the parameters such as bowel wall thickness（BWT），bowel wall stratification，mesenteric lymph nodes（MLNs），and existence of mesenteric fat hypertrophy（MFH）were recorded. Color Doppler flow imaging（CDFI）and UMA were used to evaluate the blood flow in the most thickened diseased bowel wall using Limberg scores. The diffierences of the above parameters among the 3 groups were compared. The diagnostic performance of UMA and CDFI in assessing the inflammatory activity of pediatric CD was evaluated. Results:There were statistically significant differences in BWT among the 3 groups（all P<0.05）. However，there were no statistically significant differences in MLNs among the 3 groups（all P>0.05）. Compared with the inactive CD，there were statistically significant differences in bowel wall stratification and MFH in both the mild and moderate-to-severe CD groups（all P<0.05）. When assessing bowel wall blood flow signals using CDFI，there was no statistically significant difference in blood flow signals in the bowel wall of the mild CD compared with the inactive CD（ P>0.05）. However，the blood flow signals in the bowel wall of the moderate-to-severe CD was significantly increased（ P<0.05）. There was also statistically significant difference in blood flow signals in the bowel wall between the mild and moderate-to-severe CD groups（ P<0.05）. When assessing bowel wall blood flow using UMA，there were statistically significant differences in blood flow signals in the bowel wall among all 3 groups（all P<0.05）. As the degree of inflammation increased，the blood flow signals in the bowel wall also increased significantly. ROC analysis revealed that diagnostic performance of the UMA-BMUS model was significantly better than that of the CDFI-BMUS model（AUC 0.945 vs. 0.873，sensitivity 88.9% vs. 74.1%，specificity 97.7% vs. 95.5%；all P<0.05）. Conclusions:By sensitively depicting the low-velocity and tiny blood flow signals of the inflamed bowel wall，UMA is an effective noninvasive imaging method to make semi-quantitative evaluation of the activity of pediatric Crohn's disease.

Inflammation is involved in the development of various acute and chronic diseases in the body. Sustained inflammatory responses are key driving factors for diseases such as cancer， neurodegenerative diseases， cardiovascular diseases， metabolic syndrome， inflammatory bowel disease， and arthritis. Therefore， finding anti-inflammatory drugs is crucial for the prevention and treatment of various diseases. In recent years， there has been increasing attention to finding natural drugs with minimal toxic side effects. Lonicerae Japonicae Flos and Lonicerae Flos， as traditional Chinese medicines potent in clearing heat and removing toxins， have strong biological activity and multiple pharmacological effects. They are widely distributed in the plant world and have significant medicinal value. With the continuous advancement of the research on Lonicerae Japonicae Flos and Lonicerae Flos， they have been widely used in the medical field and possess great development potential. Currently， research mainly focuses on the anti-inflammatory mechanisms of Lonicerae Japonicae Flos and Lonicerae Flos， while systematic summaries of their anti-inflammatory active ingredients are rare. Therefore， this paper focuses on the differential analysis of the anti-inflammatory active components of Lonicerae Japonicae Flos and Lonicerae Flos. In addition， it reviewed the possible mechanisms by which extracts and active ingredients of Lonicerae Japonicae Flos and Lonicerae Flos may exert anti-inflammatory effects through various pathways， such as influencing the release of cellular inflammatory factors， regulating inflammatory signaling pathways such as nuclear factor-κB （NF-κB）， mitogen-activated protein kinase （MAPK）， signal transducer and activator of transcription 3 （STAT3）， MAPK/extracellular signal-regulated kinase （ERK）/c-Jun N-terminal kinase （JNK）， phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt）/NF-κB， and Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathways， increasing antioxidant stress capacity， enhancing immune defense capabilities， and improving intestinal microbiota， aiming to provide a theoretical basis for the rational clinical application of Lonicerae Japonicae Flos and Lonicerae Flos.

Objective:To explore the correlation between hip muscle factors measured with CT imaging and recovery of independent mobility within 1 year after surgery in elderly patients with hip fractures.Methods:A prospective cohort study was conducted on the clinical data of 680 elderly patients with hip fractures admitted to Beijing Jishuitan Hospital of Capital Medical University from November 2018 to December 2019. The patients were assigned to dependent group and assistant group according to whether they regained pre-injury independent mobility within 1 year after surgery. Gender, age, body mass index, personal history, living habits, past diseases, Charlson comorbidity index, laboratory test indicators, fracture types, anesthesia types, surgical methods, rehabilitation training, time from injury to surgery, and hip muscle parameters in both groups were recorded. OsiriX software was employed in the measurement of the hip muscles to measure the muscle area and density of the gluteus maximus and gluteus medius/minimus on CT images, and the average values were calculated as hip muscle area and density. Then the variables of hip muscle area and density were converted seperately to gender-normalized Z-scores, and were divided into high-area group ( Z≥0) and low-area group ( Z<0), and high-density group ( Z≥0) and low-density group ( Z<0) respectively. Observable variables were primarily analyzed using univariate analysis between the independent group and assistant group. Those variables with statistically significant differences in the univariate analysis or would potentially affect mobility recovery according to previous researches although there were no statistical significance were included in a multivariate Logistic regression analysis. Three Logistic regression models were designed (Model 1 uncorrected, Model 2 corrected for gender, age and body mass index, Model 3 corrected for variables in Model 2 and other variables included after above-mentioned analysis) to analyze whether muscle parameters were risk factors for recovery of independent mobility. Additionally, generalized estimating equations were used for repeated measurement to analyze the correlation between hip muscle area and recovery of independent mobility after surgery. Results:Compared to the assistant group, the independent group were younger in age, with lower rate of living alone, being housebound, cognitive impairment, and Charlson comorbidity index, lower level of hemoglobin and albumin, higher rate of femoral neck fractures, lower rate of internal fixation, shorter time from injury to surgery, larger hip muscle area, and higher hip muscle density ( P<0.05 or 0.01). Multivariate Logistic regression analysis showed that, in the fully corrected Model 3, only hip muscle area remained significantly correlated with recovery of independent mobility ( P<0.05), while no significant difference was found between the high-density group and low-density group ( P>0.05). In the repeated measurement, patients in the high-area group were 1.84 times more likely to restore independent mobility than those in the low-area group ( OR=1.84, 95% CI 1.33, 2.53, P<0.01). Conclusions:Hip muscle area measured with CT imaging is closely correlated to the recovery of independent mobility within 1 year after surgery in elderly patients with hip fractures. Moreover, larger hip muscle area indicates a larger likelihood of recovery of independent mobility.

ObjectiveTo systematically review the effects of bilingual training on cognition for older adults. MethodsResearches about bilingual training for cognition for the older adults were retrieved from PubMed, Web of Science, ScienceDirect, SpringerLink, Wanfang Data, and CNKI from 2011 to May, 2021, supplemented by references backtracking and manual retrieval. The data was extracted for analysis. ResultsA total of 21 researches were included from twelve countries, which published mainly on journals of medicine, neurology, psychology, biology, etc., in 2017 and 2019. Most of the researches were prospective researches and retrospective researches, and the targeted groups including healthy people, people with dementia and people with Alzheimer's disease (AD). The objects mainly involved the effects of bilingualism on cognition, the pathways and the limitations. ConclusionBilingual training may improve the cognition for older adults, through the brain connection related with memory, attention and execution, to delay the onset of AD or dementia; which may associate with the improvement of brain structure and function, including connectivity among regions, activation of cortical circuits, and structural integrity and plasticity. The effects are mainly on execution and perception, and delaying the cognitive decline, which appear in a short term. Bilingual training may finally promote language function, maintain the integrity of the brain structures, and compensate cognitive decline using more potential neural circuits. However, these researches need more uniform criteria for subjects, more reasonable control conditions, and more uniform paradigms.
