ObjectiveTo investigate the effects of Jianpi Qinghua granules on blood glucose fluctuations in patients with newly diagnosed overweight/obese type 2 diabetes mellitus （T2DM） and Qi-Yin deficiency syndrome from the perspective of skeletal muscle mass and function， while providing new insights for the treatment of diabetes. MethodsThis study employed a randomized， double-blind， placebo-controlled design. A total of 110 newly diagnosed overweight/obese T2DM patients meeting the inclusion criteria were randomly assigned to either the traditional Chinese medicine （TCM） group （54 cases） or the control group （56 cases）. Patients in the TCM group received Jianpi Qinghua Granules， while those in the control group received a placebo. Both groups underwent dietary and exercise guidance. After 12 weeks of intervention， blood glucose fluctuations were assessed using the following parameters： time in the target blood glucose range （TIR）， mean daily blood glucose （MBG）， standard deviation of mean daily blood glucose （SDBG）， mean amplitude of glycemic excursions （MAGE）， coefficient of variation of blood glucose （CV）， glycated hemoglobin （HbA1c） achievement rate， fasting plasma glucose （FPG）， and 2 hour postprandial glucose （2 hPG）. Skeletal muscle mass was measured by dual-energy X-ray absorptiometry （DXA）， while skeletal muscle function was evaluated using a handheld dynamometer for distal muscle strength and a 5-time sit-to-stand test for lower limb function. Additionally， pancreatic islet function and TCM syndrome scores were analyzed. ResultsNo significant differences were observed in baseline data between the two groups before intervention， ensuring comparability. After treatment， compared to the control group， the TCM group showed a significant increase in TIR （P<0.01）. While the SDBG and CV decreased， and MBG and MAGE increased in the TCM group， these differences were not statistically significant. Notably， the TCM group exhibited significant reductions in 2 hPG （P<0.01） and HbA1c （P<0.05）， though the decrease in FPG was not statistically significant. The HbA1c achievement rate in the TCM group was significantly higher than that in the control group （χ²=45.498， P<0.01）. In terms of skeletal muscle mass and function， the TCM group demonstrated a significant increase in handgrip strength （P<0.01） and a significant reduction in the 5-time sit-to-stand duration （P<0.05）. However， although body fat percentage increased， leading to a decrease in skeletal muscle mass and the ratio of skeletal muscle to fat， these changes were not statistically significant. For pancreatic islet function， the TCM group showed significant reductions in fasting insulin （FINS） and homeostasis model assessment of insulin resistance （HOMA-IR） （P<0.01）. Additionally， the TCM syndrome score in the TCM group was significantly reduced （P<0.01）. ConclusionJianpi Qinghua granules may reduce blood glucose fluctuations in newly diagnosed overweight/obese T2DM patients with Qi-Yin deficiency syndrome by enhancing skeletal muscle function， improving pancreatic islet function， and ameliorating related TCM syndromes.

ObjectiveTo explore the application of virtual reality biofeedback training combined with oral localization therapy in dysphagia after oral cancer surgery. MethodsFrom May, 2023 to July, 2024, 86 patients with dysphagia after oral cancer surgery in Zhejiang Provincial People's Hospital were randomly divided into control group (n = 43) and experimental group (n = 43). The control group received conventional swallowing function training, while the experimental group added virtual reality biofeedback training combined with oral positioning therapy, for four weeks. The Standardized Swallowing Function Assessment Scale (SSA), Functional Oral Intake Scale (FOIS) and M.D.Anderson Dysphagia Inventory (MDADI) were used for evaluation before intervention, and two weeks, four weeks and eight weeks after intervention.

For scores of FOIS, the main effects of group (F = 59.601, P < 0.001, η²_p = 0.415) and time (F = 89.464, P < 0.001, η²_p = 0.516), as well as the interaction effect (F = 7.990, P < 0.001, η²_p = 0.087) were all significant. For scores of MDADI, the main effects of group (F = 33.133, P < 0.001, η²_p = 0.283) and time (F = 49.650, P < 0.001, η²_p = 0.371), as well as the interaction effect (F = 3.224, P = 0.023, η²_p = 0.037) were all significant. ConclusionVirtual reality biofeedback training combined with oral localization therapy could improve the swallowing function, oral feeding ability and overall quality of life of patients with dysphagia after oral cancer surgery.

Objective:To assess the nutritional status and risk of children with cyclic vomiting syndrome（CVS）and to provide a clinical evidence for nutritional support.Methods:A total of 160 children diagnosed with CVS and 160 healthy controls were prospectively enrolled in the study，who were admitted to Beijing Tsinghua Changgung Hospital from April 2021 to February 2024.Nutritional status was assessed by anthropometric indices（height，weight，and body mass index），and it was expressed in standard deviation score（Z score）.Nutritional risk screening tool STRONGkids was applied to nutritional risk screening，and the laboratory assessment（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）were measured.Results:Among the 160 cases，there were 73 males and 87 females，including 18 cases of mild seizures and 142 cases of moderate and severe seizures，with the average onset age of（47.54±2.96）months and an average diagnosis age of（74.89±3.68）months.The average duration from the first attack to diagnosis was（27.35±2.36）months，and the average course of the disease was（41.35±2.63）months.The malnutrition rate of children in CVS was 36.9%（59/160），of which 18.1%（29/160）was severely malnourished.There was a statistically significant difference in the weight-for-age Z-score（WAZ），height-for-age Z-score（HAZ），and body mass index-for-age Z-score（BAZ）between the CVS group and the control group（ P<0.001）.We found a statistically significant difference in laboratory indicators（albumin，pre-albumin，hemoglobin，urea nitrogen and creatinine）between the two groups（all P<0.001）and hemoglobin was positively correlated with WAZ，HAZ and BAZ（ r=0.346,0.250,0.277，all P<0.01）.Using the STRONGkids nutritional risk screening tool，there were 43 cases with moderate nutritional risk and 117 cases with high nutritional risk，and children with high nutritional risk were likely to have lower WAZ，HAZ and BAZ than the children with moderate nutritional risk，and there was a significant difference in WAZ，HAZ，BAZ，hemoglobin，and creatinine between the two groups（ P<0.05）.And there was a correlation between the degree of CVS attack and nutritional risk grouping（ r=0.543， P<0.001）. Conclusion:Children with CVS have a high incidence of malnutrition，and the serum albumin，prealbumin，hemoglobin，urea nitrogen and creatinine levels are of great value for nutritional assessment.The STRONGkids score method helps to evaluate nutritional risk in children with CVS.

Objective:To investigate the characteristics of gut microbiota distribution in children with cyclic vomiting syndrome（CVS）complicated by constipation.Methods:The children with CVS, aged from 1 to 16 years, who were admitted to Beijing Tsinghua Changgung Hospital from June 2022 to January 2024, were divided into constipation group and normal group(non-constipation group) according to whether they were complicated with constipation or not.The clinical data and stool samples of children were collect. The abundance, diversity and composition of intestinal flora in fecal samples of two groups were detected by metagenomics sequencing.Results:A total of 20 children with CVS were collected, including 10 patients in constipation group and 10 patients in normal group.There were no significant differences in general demographic data between the two groups, including age at admission, age at first onset, body mass index, gender distribution, disease severity, endoscopic findings, and abdominal pain patterns.Microbiome analysis yielded 470 operational taxonomic units (OTUs), with 414 OTUs identified in normal group and 56 OTUs in constipation group. The abundance and diversity of intestinal flora in constipation group were significantly lower than those in normal group. Principal coordinate analysis and principal component analysis indicated significant structural differences in gut microbiota composition between the two groups. LEfSe analysis revealed distinct taxonomic patterns between the two groups, with the normal group demonstrating predominant representation of Firmicutes at the phylum level, while the constipation group showed higher relative abundance of Bacteroidetes and Actinobacteria. KEGG pathway analysis revealed that the carbon metabolism pathways was significantly enriched in the constipation group.Conclusion:There are significant differences in intestinal flora between CVS children with and without comorbid constipation.Bacteroides and Actinomycetes play an important role in constipation of children with CVS. The diversity and metabolic function of intestinal flora may be one of the pathological mechanisms of CVS complicated with constipation.

Objective:To investigate the impact of different CT reconstruction kernels on the quantitative analysis of small pulmonary vessels in patients with chronic obstructive pulmonary disease (COPD) and high-risk patients.Methods:This study was a cross-sectional study. Clinical and imaging data of 73 COPD and high-risk patients visiting the China-Japan Friendship Hospital between March and April 2024 were retrospectively analyzed. All patients underwent high-resolution CT of the chest and pulmonary function tests, with the ratio of forced expiratory volume in one second to forced vital capacity (FEV 1/FVC) obtained. The raw CT data were reconstructed using different kernels: the FC86 group used the adaptive iterative dose reduction(AIDR) 3D standard lung sharp reconstruction algorithm, the FC18 group used the AIDR 3D standard Body standard reconstruction algorithm, the advanced intelligent clear-IQ engine(AiCE) Lung group used the AiCE deep learning reconstruction algorithm for lung, and the AiCE Body group used the AiCE deep learning reconstruction algorithm for body. Image signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR) and image noise were calculated. The pulmonary vessel segmentation & Measurement software was used to segment and extract pulmonary arteries and veins of four groups in thin-slice whole-lung CT imaging, obtaining the ratio of small pulmonary arteries (%V artery<5) and the ratio of small pulmonary veins (%V vein<5). The One-way repeated measures ANOVA or Friedman test was used to compare the differences in SNR, CNR, image noise, %V artery<5, and %V vein<5 among the four groups, followed by Bonferroni post hoc or Bonferroni-Dunn test with P-value correction to analysis differences between subgroups. The correlations between %V artery<5 and FEV 1/FVC, as well as between %V vein<5 and FEV 1/FVC were analyzed using Spearman rank correlation analysis in all four groups. Results:The overall differences in image noise, SNR, and CNR in the AiCE Lung, AiCE Body, FC18, and FC86 groups were statistically significant ( P<0.001). Except for the difference in CNR values between the AiCE Lung group and the FC18 group, which was not statistically significant ( P=0.192), all differences were statistically significant ( P<0.016 7). The overall differences in %V artery<5 values and %V vein<5 values in the AiCE Lung, AiCE Body, FC18, and FC86 groups were statistically significant ( P<0.001). The %V artery<5 and %V vein<5 values in the FC18 group were lower than those in the AiCE Lung, AiCE Body, and FC86 groups ( P<0.016 7), and the rest of the differences were not statistically significant ( P>0.016 7). %V artery<5 and %V vein<5 were positively correlated with FEV 1/FVC in all 4 groups ( P<0.05), with the highest correlation coefficient between %V vein<5 and FEV 1/FVC in the AiCE Body group ( r=0.501, P=0.001). Conclusions:DLR-AiCE-based kernel reconstruction optimizes image quality and significantly affects the results of quantitative parameters of small pulmonary vessels. The reconstruction kernel prioritized for quantitative analysis of small vessels within the lungs in COPD based on the CT scanner in this study is AiCE Body.

Objective To analyze the disability level and long-term care needs assessment policies issued by 49 pilot cities in China's long-term care insurance system,providing insights for further improvement of the system.Methods Policy documents related to long-term care insurance,published between June 2016 and December 2024 on official platforms of local governments,the Ministry of Human Resources and Social Security,the National Healthcare Security Administration,and the National Public Service Platform for Standards Information,were retrieved.A comparative analysis was used to summarize and compare the content of these policy texts.Results Currently,there are 49 pilot cities implementing the long-term care insurance system in China.47 cities have issued disability level assessment standards,with 38 cities adopting the trial standards issued by the National Healthcare Security Administration.In 42 pilot cities,the disability level assessment includes indicators such as activities of daily living,cognitive function,and sensory and communication abilities.22 cities have issued policies related to care needs assessment.In most cities,the care needs assessment partially or fully includes indicators from the disability level assessment.Conclusion There is no national uniformity in disability level assessment standards,and the care needs assessment framework needs further improvement.It is recommended to standardize disability level assessment criteria,clearly delineate the boundaries and content of disability level and care needs assessments,and enhance the development of the care needs assessment system.

Objective:To investigate the mediating effect of psychological flexibility between recurrence risk perception and health behavior in stroke patients.Methods:From July to December 2024, 233 stroke patients at the First Affiliated Hospital of Zhengzhou University were selected using convenience sampling. Electronic questionnaires were used to collect patients' general information, perception of stroke recurrence risk, health behavior, and psychological flexibility.Results:The scores for recurrence risk perception, psychological flexibility, and health behavior of 233 stroke patients were (39.75±4.39), (47.45±4.19), and (54.04±3.78), respectively. Health behavior were positively correlated with recurrence risk perception ( r=0.495, P<0.01), and negatively correlated with psychological flexibility ( r=-0.367, P<0.01). Psychological flexibility partially mediated the relationship between recurrence risk perception and health behavior, with an effect value of 0.080 and an effect proportion of 17.5% (0.080/0.458) . Conclusions:Recurrence risk perception not only directly predicts health behavior in stroke patients but also indirectly influences their health behavior through psychological flexibility. Healthcare providers should enhance recurrence risk perception among stroke patients and incorporate the improvement of psychological flexibility as part of intervention strategies to improve patients' health behavior.
