Objective: To analyze the association of eating dining locations and their association with nutritional status among Chinese children aged 6-17 years,so as to provide reference for guiding children s reasonable diet. Methods: Stratified random cluster sampling was used to select children aged 6 to 17 years from 28 cities and rural areas of 14 provinces in East, North, Central, South, Southwest, Northwest, Northeast of China, and a total of 52 535 children were included in the study from 2019 to 2021. Information including dining locations, demographic characteristics, dietary intakes and physical activity were collected through a questionnaire survey. Fasting body height and weight were measured in the morning. Unordered multiclass Logistic regression analysis was conducted to assess the relationship between dining locations and nutritional status in children. Results: Regarding children s dining locations, 66.3% ate breakfast at home,25.8% ate breakfast at school,7.9% ate breakfast outside (small dining tables, restaurants, stalls, etc.); 67.7% ate dinner at home,29.0% ate dinner at school,3.3% ate dinner outside; and 63.6% ate lunch at school,30.8% ate lunch at home,5.7% ate lunch outside. The prevalence rates of overweight/obesity and undernutrition were 28.6% and 9.3%, respectively. The adjusted multiclass Logistic regression analysis (controlling for age, region, parental education, household income, total energy intake, and moderate-to-vigorous physical activity) demonstrated that, compared to eating at home, school based breakfast and dinner consumption was associated with significantly lower overweight/obesity risks for both genders (boys: breakfast OR =0.70, 95% CI =0.65-0.75; dinner OR =0.80, 95% CI = 0.74- 0.86; girls: breakfast OR = 0.89 , 95% CI = 0.82-0.96; dinner OR =0.88, 95% CI =0.81-0.95), whereas eating lunch away from home significantly increased overweight/obesity risks (boys: OR =1.32, 95% CI =1.17-1.48; girls: OR =1.43, 95% CI =1.26- 1.62 ), with all associations being statistically significant ( P <0.05). After adjusting for confounding factors, boys who ate breakfast away from home showed a significantly reduced risk of undernutrition ( OR =0.80,95% CI =0.66-0.97), while those consuming lunch away from home had an increased risk ( OR =1.26, 95% CI =1.01-1.57) ( P <0.05). Conclusions The choice of dining locations for children is becoming more diverse, and a relatively high proportion of children eat meals outside the home and at school. Eating out have a higher risk of malnutrition for children. School feeding may be beneficial to children s physical health.

BackgroundThe issue of school absenteeism due to school refusal in adolescents has become increasingly prominent. Acceptance and Commitment Therapy （ACT） has been applied successfully to improve depression， anxiety， and psychological flexibility in adolescents， while few studies have tested the effect of ACT intervention on above-mentioned psychological aspects and return-to-school rate in adolescents with school absenteeism. ObjectiveTo explore the effect of ACT on depression， anxiety， psychological flexibility and return-to-school rate in school absenteeism adolescents， and to provide a broader evidence base for clinical interventions. MethodsFrom May to June 2024， a sample of 50 adolescents with Shenzhen school registration who had been suspended from school for more than a consecutive month for school refusal were recruited based on Wechat official account platform. The adolescents were divided into study group and control group by random number table method. Both groups received psychological education with the theme of 'Causes and Coping Strategies of School Refusal'， and study group added a 6-week ACT intervention with weekly 1-hour sessions. At baseline and after treatment， Patients’ Health Questionnaire Depression Scale-9 item （PHQ-9）， Generalized Anxiety Disorder Scale-7 item （GAD-7） and Comprehensive assessment of Acceptance and Commitment Therapy processes （CompACT） were used for the clinical evaluation. ResultsA total of 45 （90.00%）adolescents completed the study， including 25 in study group and 20 in control group. Analysis revealed that study group scored higher on PHQ-9 and GAD-7， while lower on total CompACT score， openness dimension and awareness dimension compared with control group， with statistical significance （F=7.786， 10.334， 12.922， 14.374， 3.075， P<0.05 or 0.01）. After intervention， the rate of return-to-school was higher in study group than in control group （40.00% vs 10.00%， χ²=5.114， P<0.05）. ConclusionACT intervention for adolescents with school absenteeism may alleviate depression and anxiety， improve their psychological flexibility and increase return-to-school rate.［Funded by the "14^th Five Year Plan" for Social Sciences Project in Jiangxi Province （number， 24JY41D）； Science and Technology Planning Project of Shenzhen Municipality （number， 20210617155253001）］

Objective:To investigate the mid-and long-term clinical efficacy of modified Colonna arthroplasty in the treatment of unilateral dislocation type developmental dysplasia of hip (DDH) in adolescents.Methods:A total of 28 adolescent DDH patients with unilateral dislocation who underwent modified Colonna capsular arthroplasty from January 2016 to January 2018 in the 920th Hospital of Joint Logistics Support Force of People's Liberation Army were retrospectively analyzed. There were 4 males and 24 females, aged 16.5±5.0 years (range, 10-25 years). The mean body mass index was 21.2±1.1 kg/m 2 (range, 18.7-24.1 kg/m 2). According to DDH classification, 10 cases were Tonnis type III and 18 cases were Tonnis type IV. The postoperative lateral center-edge angle, acetabular coverage, femoral anteversion angle and leg length discrepancy were measured. The operation time, intraoperative blood loss, visual analogue scale (VAS) of hip pain, Harris hip score (HHS) and congenital dislocation of the hip score were recorded. Results:All patients successfully completed the operation and were followed up for 72.1±5.2 months (range, 60-84 months). The operation time was 81.6±4.3 min (range, 70-90 min), the intraoperative blood loss was 177.5±12.6 ml (range, 160-200 ml), and the hospital stay was 6.8±0.7 days (range, 6-9 days). The VAS score of the hip joint was 1.8±0.6 before operation and 2.3±0.6 at the last follow-up, and the difference was not statistically significant ( t=2.845, P=0.224). The preoperative HHS score was 57.1±5.9, and it increased to 87.3±4.0 at the last follow-up, and the difference was statistically significant ( t=-22.141, P=0.001). At the last follow-up, the femoral anteversion angle was 17.0°±1.5°, which was lower than that before operation 41.6°±2.4°, with a statistically significant difference ( t=-44.868, P=0.008). The leg length discrepancy was 10.2±2.3 mm, which was lower than that before operation (26.4±6.1 mm), with a statistically significant difference ( t=-12.892, P<0.001). The lateral center-edge angle was 28° (26°, 30°), and the acetabular coverage rate was 78% (76%, 79%). The curative effect evaluation standard score of congenital dislocation of the hip was 24 (16.7, 25.7) points, including 7 excellent cases, 14 good cases, 4 fair cases, and 3 poor cases. The excellent and good rate was 75% (21/28). Conclusion:The modified Colonna arthroplasty for the treatment of unilateral dislocation DDH in adolescents has good mid-and long-term hip function recovery and radiographic improvement.

Objective:To explore the efficacy and safety of hyaluronic acid filler VYC-20L for full-face lifting in aesthetic seeking patients.Methods:Between November 2020 and November 2021, a total of 216 aesthetic seeking patients were enrolled in Shanghai Chingho Outpatient Department, World Path Clinic International, Qihe Medical Beauty Hospital and Qinhuangdao Qiaozhi Beauty Hospital, including 37 males and 179 females, aged 25-67 (41.42±10.93) years. According to the needs and requirements, the novel injection technique of " ROYGBbP-rainbow lifting method" was used to inject hyaluronic acid filler VYC-20L. The global aesthetic improvement scale (GAIS) and the treatment satisfaction questionnaires were scored and evaluated before the injection, and at follow-up visits 1, 6, and 12 months after the injection. Any adverse reaction or adverse events presenting or reported by the patients post-injection were recorded.Results:At 1 month, 6 months and 12 months after the injection, about 203 (94.0%), 208 (96.3%) and 205 (94.9%) of the aesthetic seeking patients rated their full-face appearance as " excellently improved" or " much improved" on the GAIS, respectively. And 12 months after the injection, the overall facial satisfaction scores and appearance recognition scores of all aesthetic seeking patients were all significantly higher than those before injection ( P<0.01). 197 (91.2%), 198 (91.7%) and 198 (91.7%) of the aesthetic seeking patients were " very satisfied" or " relatively satisfied" with the treatment at 1 month, 6 months and 12 months, respectively. Treatment site responses most frequently reported were tenderness, bruising, topical swelling and skin redness. Most of the symptoms were moderate or mild feeling, lasting for no more than two weeks. Conclusions:The application of hyaluronic acid filler VYC-20L is safe and effective for full-face lifting in aesthetic seeking patients, which can significantly improve facial sagging and rejuvenate the face. The effect of improvements can last for 12 months.

Objective To study the correlation between serum thioredoxin 1(TRX-1)and nucleotide-bind-ing oligomerization domain-like receptor protein 3(NLRP3)expression levels and functional dyspepsia(FD)in children.Methods A total of 45 children with FD who were admitted to Shijiazhuang Maternal and Child Health Hospital from May 2022 to June 2023 were enrolled as the FD group.Another 40 healthy children were selected as the control group.Real-time fluorescence quantitative PCR was used to measure the expression lev-els of serum TRX-1 and NLRP3 mRNA.Spearman correlation analysis was used to analyze the correlation be-tween the expression levels of serum TRX-1 mRNA,NLRP3 mRNA and FD related scores.Multivariate Lo-gistic regression was used to analyze the influencing factors of FD.Results The expression levels of TRX-1 mRNA and NLRP3 mRNA in FD group were higher than those in control group(P＜0.05).The mild and moderate FD groups had significantly lower serum TRX-1 mRNA and NLRP3 mRNA expression levels than the severe FD group,and the mild FD group had significantly lower serum TRX-1 mRNA and NLRP3 mRNA expression levels than the moderate FD group(P＜0.05).The expression levels of TRX-1 mRNA and NLRP3 mRNA in serum were positively correlated with egigastric pain,abdominal distension or epigastric discomfort,nausea and vomiting(P＜0.05),but were not correlated with early satiety,loss of appetite or food intake,and belching(P＞0.05).The expression level of serum NLRP3 mRNA was positively correlated with the total score(P＜0.05),while the expression level of serum TRX-1 mRNA was not correlated with the total score(P＞0.05).The increased levels of serum TRX-1 mRNA and NLRP3 mRNA were independent risk factors for FD(P＜0.05).Conclusion The expression levels of TRX-1 and NLRP3 may play an important role in the pathogenesis of FD.

It is found that acupuncture can significantly improve the clinical symptoms of rheumatoid arthritis (RA) such as pain and joint stiffness, and improve rheumatoid factor, high-sensitivity CRP, ESR and other clinical indicators. It can inhibit the proliferation of synovial cells, the apoptosis of chondrocytes, and regulate polarization balabce of mononuclear macrophages, T cells, as well as inhibit the inflammatory function of multiple immune cells, in order to improve inflammation state of RA joints. In clinical treatment of RA, bladder meridian, stomach meridian, spleen meridian , and Governor Vessel are mostly selected. Acupoints with the efficacy of warming meridian, dispelling coldness and dredging collaterals were commonly selected such as Zusanli (ST36), Yanglinquan (GB34), Dazhui (GV14), Quchi (LI11). Several researches have proved that combined therapy of acupuncture and medicine is worthy promotion in clinic.

Objective To detect the expression level of 4-aminobutyrate aminotransferase(ABAT)in bone marrow of patients with myelodysplastic syndrome(MDS),and analyze its influence on clinicopathological features and prognosis of patients.Methods From January 2016 to March 2020,92 patients with MDS and 30 patients with acute myeloid leukemia(AML)from the First Affiliated Hospital of Xingtai Medical College were retrospectively collected.Meanwhile,30 patients with immunothrombocytopenia who did not develop MDS or other clonal diseases of the blood system during a 3-year follow-up were collected as control group.Real-time quantitative fluorescent PCR(qRT-PCR)was used to detect the relative expression level and methylation level of ABAT mRNA of all patients,and the relative expression level and methylation level of ABAT mRNA among different clinical characteristics of MDS patients were compared.Multivariate logistic regression analysis was used to analyze the risk factors affecting the adverse prognosis of MDS.The clinical value of detecting ABAT methylation level in predicting poor prognosis of MDS patients was analyzed by receiver operating characteristic(ROC)curve.Kaplan-Meier method was used to calculate the 3-year survival rate between groups with different ABAT mRNA relative expression levels and methylation levels,and log-rank test was used for their comparison.Results The expression level of ABAT mRNA in MDS group(0.42±0.08)was lower than that in control group(0.56±0.15)and AML group(0.52±0.10),while the methylation level of ABAT(32.51±5.32)was higher than that of AML group(26.21±4.58)and control group(10.25±4.31),and the differences were significant(t=4.251,4.562;10.415,8.326,all P<0.001).The methylation level of ABAT in high-risk patients(42.65±5.32)was higher than that in low-risk patients(25.63±4.16),intermediate-risk-1 patients(30.59±2.51)and intermediate-risk-2 patients(33.25±3.69)by IPSS risk grade,and the differences were significant(t=8.329,7.077,15.874,all P<0.001).Poor Karyotype analysis result[OR(95%CI):4.973(1.524～8.581),P=0.004],high IPSS risk grade[OR(95%CI):8.542(2.365～14.521),P<0.001]and ABAT hypermethylation level[OR(95%CI):6.178(1.589～13.021),P<0.001]were the risk factors affecting the poor prognosis of MDS.The cut-offvalue of ABAT methylation level to predict the poor prognosis of MDS were 30.54,and the area under the curve(AUC),the sensitivity and specificity were 0.92,0.874 and 0.851,respectively.The 3-year survival rate of the high ABAT methylation group(>30.54)was 66.67%,which was lower than that of the low ABAT methylation group(≤30.54)was 93.18%,with significant difference(Log-rank x2=9.814,P=0.002).Conclusion The ABAT methylation levels in MDS bone marrow increase,which is a risk factor affecting the poor prognosis of patients.ABAT basal level>30.54 is expected to become a factors predicting the poor prognosis of patients.

Objective:To explore the clinical efficacy of the San Diego osteotomy in treating developmental dysplasia of the hip (DDH) in children.Methods:A retrospective analysis was conducted on 33 pediatric cases of posterolateral acetabular dysplasia treated with the San Diego osteotomy at the 920th Hospital of the People's Liberation Army Joint Logistics Support Force in China from August 2018 to August 2022. The cohort included 3 males (4 hips) and 30 females (36 hips), with an average age of 4.9±1.4 years (range, 2-8 years). Among these, 32 cases (38 hips) were diagnosed with DDH, and 1 case (2 hips) with paralytic dislocation of the hip. According to the T?nnis classification, 3 hips were classified as type II, 25 hips as type III, and 12 hips as type IV. The San Diego osteotomy technique was utilized to enhance the posterior lateral acetabular coverage, combined with femoral osteotomy to adjust the hip abduction, flexion, and adduction angles. Postoperative outcomes were assessed using the modified Severin radiographic classification and the McKay grading system.Results:All 33 patients were followed up for an average of 37.70±18.44 months (range, 12-74 months). No cases of postoperative hip redislocation or residual acetabular underdevelopment were observed. The hip abduction angle improved from 24.98°±3.48° at 6 weeks postoperatively to 37.28°±4.63° at the 3-month follow-up, and 64.05°±3.82° at the 6-month follow-up, with a statistically significant difference ( F=77.327, P<0.001). The hip flexion angle increased from 26.34°±5.05° at 6 weeks postoperatively to 76.53°±4.38° at 3 months, and 106.47°±2.29° at 6 months, also showing a statistically significant difference ( F=54.377, P<0.001). The hip adduction angle progressed from 1.73°±1.18° at 6 weeks postoperatively to 12.33°±1.97° at 3 months, and 29.03°±4.17° at 6 months, with a significant difference ( F=45.162, P<0.001). The McKay hip joint grading system indicated 11 excellent, 20 good, and 9 acceptable outcomes, yielding an overall excellent and good rate of 78%. The Severin radiographic grading revealed 16 hips at grade I and 24 hips at grade II. Five patients (5 hips) experienced transient vascular compromise of the femoral head at 3 months postoperatively, which resolved after a 1-month non-weight-bearing period. At the final follow-up, one patient had residual femoral head enlargement in the right hip, while the remaining 32 cases showed satisfactory ossification and remodeling of the femoral head. Conclusion:The San Diego osteotomy significantly enhances hip joint range of motion and results in satisfactory hip joint function in children with developmental dysplasia of the hip

The gut microbiota is a vast microbial ecosystem,specifically present in the organism and plays an important regulatory role in the body's health or disease state together with its metabolites.After spinal cord injury,the complex pathophysiology at the site of trauma makes axonal regeneration difficult,and the autonomic motor dysfunction induced by spinal cord injury disrupts gastrointestinal function and causes gut microbiota imbalance.The previous clinical outcomes of neurorepair strategies after spinal cord injury have not been ideal.The dysregulated gut microbiota and neuroinflammation after spinal cord injury are closely associated with the prognosis of the patients.The potential mechanisms by which the gut microbiota may influence the neuroinflammation after spinal cord injury may include the activation of gut-associated lymphoid tissue and disruption of the intestinal barrier by the imbalanced microbiota,and gut microbiota and its metabolites such as lipopolysaccharides(LPS),short chain fatty acids(SCFAs),5-hydroxytryptamine(5-HT),and tryptophan,as well as immune cells,inflammatory factors,and neurotransmitters the local inflammatory response in the spinal cord through the circulatory system.This paper revews the studies on the changes in gut microbiota after spinal cord injury and their effects on the spinal cord neuroinflammation,providing new targets and new ideas for improving the neuroinflammation after spinal cord injury.
