Objective: To investigate the impact of milk and egg supplementation on body composition and bone mineral density of rural primary school students in Yunnan Province, so as to provide a reference for developing targeted nutritional intervention strategies. Methods: In December 2023, a cluster sampling method was adopted to select students from grades one to three in four primary schools each from Jinggu and Shidian countys of Yunnan Province, as the intervention group (662 students). Additionally, two boarding primary schools were selected from each county based on the principle of matching scale and student numbers as the control group (455 students). Starting from April 2023, the intervention group received 200 mL milk and 50 g eggs during the break on school days for 8 months, while the control group maintained their usual diet behavior. Body composition was measured by using bioelectrical impedance analysis, and distal radial bone mineral density was assessed via dual energy X-ray absorptiometry in April and December 2023. The intervention effects were analyzed by using a difference in-differences approach. Results: The final measurements of body fat percentage, skeletal muscle mass and fat free mass of the intervention group and the control group of primary school students were significantly higher than the baseline values, and the net effect of milk and egg intervention on these body composition indicators was not statistically significant ( P >0.05, both before and after adjustment). In contrast, bone mineral density increased significantly by 0.02 g/cm 2 in the intervention group. The net intervention effect on bone mineral density was statistically significant ( β=0.02, 95%CI =0.00-0.04), and remained significant after model adjustment ( β=0.02, 95%CI =0.00-0.04) (both P < 0.05). Subgroup analysis showed statistically significant effects of the intervention among girls ( β=0.02, 95%CI =0.00-0.04), day students ( β=0.04, 95%CI =0.01-0.07), and students with normal nutritional status ( β=0.02, 95%CI =0.00-0.04) (all P <0.05). No significant effect of milk and egg supplementation was observed on body composition indicators (all P <0.05). Conclusions Milk and egg supplementation can improve bone mineral density among rural primary school students in Yunnan Province. It is recommended that rural school aged children should increase intake of milk and eggs to support growth and development.

Objective:To explore the characteristics of depression,anxiety,and stress symptoms among Chinese men who have sex with men(MSM),to determine the links of psychological resilience with these symptoms at the symptom level,and to provide insights for tailoring mental health intervention measures for MSM.Methods:A cross-sectional survey was conducted in southwestern China(Chongqing and Sichuan)from May to August 2022.The Depression,Anxiety,and Stress Scale-21 was used to assess mental health-related symptoms in MSM.Psychological resilience was evaluated using the brief version of the Connor-Davidson Resilience Scale.A regularized partial correlation network was constructed,and then a Bayesian network was established to identify potential causal rela-tionships in symptoms.A flow network was used to explore the link between psychological resilience and symptoms of anxiety,depres-sion,and stress.Results:A total of 938 MSM were included in the analysis.The proportion of MSM with depression,anxiety,and stress was 29.74%."Panic","scared","no relax",and"down-hearted"showed high expected influence.Bridging symptoms were"panic","down-hearted",and"agitated".Central and bridging symptoms also appeared at the top of the Bayesian network.Psychological resil-ience was negatively correlated with"no initiative","down-hearted","meaningless","panic",and"no relax".Conclusion:Central symptoms"panic","scared","no relax",and"down-hearted",as well as bridging symptoms"panic","down-hearted",and"agi-tated"are identified through network analysis.The potential causal priority of these symptoms is prominent.Interventions tailored to central and bridging symptoms may be effective,and interventions for enhancing psychological resilience may alleviate negative emotion-related symptoms,especially depressive symptoms in the MSM population.

OBJECTIVE Aimed to investigate the impact of comorbid asthma on chronic rhinosinusitis with nasal polyps(CRSwNP)and identify key proteins and signaling pathways.METHODS Proteomic methods were employed to analyze differentially expressed proteins(DEPs)in nasal lavage fluid(NLF)from control,CRSwNP,and CRSwNP with asthma groups.DIA quantitative analysis technology was used to assess the gradient changes of DEPs among the three groups to determine key proteins affected by comorbid asthma in CRSwNP.RESULTS Compared to the control group,1 377 and 1 006 DEPs were identified in the CRSwNP and CRSwNP with asthma groups,respectively.Peroxiredoxin-5(PRDX5),Ran-Binding Protein 1(RanBP1)(upregulated),and Keratin 9(KRT9)(downregulated)were identified as key proteins affecting CRSwNP with asthma.CONCLUSION Comorbid asthma may promote the occurrence and development of nasal polyps through specific key proteins and signaling pathways,providing new molecular insights into the interaction between CRSwNP and asthma.

Objective:To investigate the clinical features of primary intestinal lymphangiectasia (PIL).Methods:This study was a retrospective case series study. Fifty consecutive patients diagnosed with PIL in Department of Lymphatic Surgery, Beijing Shijitan Hospital, Capital Medical University from March 2019 to March 2021 were included and their clinical data was retrospectively reviewed. There were 20 males and 30 females included, with an age of ( M(IQR)) 14 (40) years (range:0 to 67 years). No patient had the family history. There were 26 children, including 9 males and 17 females, aged 0 (7) years (range:0 to 14 years). There were 24 adults, including 11 males and 13 females, aged 40 (26) years (range:20 to 67 years). The clinical manifestations and the results of laboratory examinations, gastrointestinal endoscopy, 99Tc m-labeled human albumin ( 99Tc m-HSA) scintigraphy, 99Tc m-DX scintigraphy, direct lymphangiography (DLG), histopathology, diet treatment, surgical intervention, and clinical symptom remission at discharge were collected. Comparisons between groups were performed using independent samples t-test, Mann-Whitney U test, or χ2 test. Results:Among the 50 cases of PIL, the main manifestations were edema (86.0%), diarrhea (76.0%), and abdominal effusion (48.0%). Lymphedema (36.0%) and chylous ascites (18.0%) were not rare in PIL patients. In 99Tc m-HAS scintigraphy, 95.9% (47/49) cases showed signs of intestinal protein loss, and 91.7% (44/48) ceses showed positive findings in 99Tc m-DX scintigraphy. In DLG, 97.8% (45/46) cases showed signs of thoracic duct obstruction, 82.6% (38/46) cases showed retroperitoneal lymphatic hyperplasia, and 23.9% (11/46) cases showed backflow of contrast agent into intestine. No significant difference was seen in gender, course of disease, clinical manifestation, serum level of albumin or globulin, lymphocyte count, positive rate of fecal occult blood and prevalence of lymphedema between adults and children (all P>0.05). Conclusions:The clinical presentations of PIL between children and adults had no significant difference. The diagnosis of PIL should be made according to clinical manifestation, 99Tc m-HAS scintigraphy, 99Tc m-DX scintigraphy, DLG, gastrointestinal endoscopy and pathological findings.

Objective:To investigate the characteristics, diagnosis and therapeutic effect of acquired lymphangiectasia of the vulva (ALV).Methods:A retrospective analysis of clinicopathological and follow-up data was conducted on the patients treated in Capital Medical University Affiliated Beijing Shijitan Hospital due to female ALV from July 2009 to July 2023. The patients who completed the staged operations [partial labiectomy and reconstruction + thoracic ductplasty and (or) perineal lymphovenous anastomosis] were included in the study and followed up. The improvement of perineal swelling, blister range, fluid leakage volume and frequency were evaluated through outpatient visits by the symptom rating scale of ALV (hereinafter referred to as the symptom rating scale) before and after surgery.Results:A total of 48 patients were treated due to ALV from July 2009 to July 2023, of which 98% (47/48) were postoperative pelvic malignant tumors and 94% (45/48) had a history of radiotherapy. A total of 10 patients with ALV who completed the staged operations were included in this study. (1) Clinical characteristics and diagnosis: 10 patients had a median age of 60 years old (50, 63 years old ). The median duration from cervical cancer surgery and radiation therapy to vulvar swelling was 1.5 years (0.0, 2.0 years), and the median duration from vulvar swelling to blister formation and leakage was 0.0 years (0.0, 4.8 years). Seven patients (7/10) had a history of recurrent erysipelas; 7 patients (7/10) had the most severe symptom (widespread blisters, persistent fluid leakage, and large amount of fluid leakage); noncontrast magnetic resonance lymphography (NCMRL) showed edema signals in the perineal region of all the patients, and increase of agent in the perineal region was observed in lymphoscintigram (LS). (2) Surgical treatment and postoperative pathological examination: of the 10 ALV patients who completed staged surgical treatment, 6 cases (6/10) were diagnosed with thoracic duct outlet obstruction and underwent thoracic ductplasty and partial labiectomy and reconstruction. Perineal lymphovenous anastomosis and partial labiectomy and reconstruction were performed in 4 cases (4/10) without thoracic duct outlet obstruction. Postoperative routine pathological examination of 10 patients (10/10) showed dermal papilla lymphangiectasia. Immunohistochemical tests were performed on 5 patients, all of which were positive for D2-40 and negative for CD 34. (3) Efficacy: 8 patients completed the postoperative follow-up, and the median follow-up time was 31.0 months (17.5, 78.3 months). The perineal swelling and the blister fluid leakage were all significantly improved after the staged operations. All indexes of the symptom rating scale, including the degree of perineal swelling, blister range, fluid leakage volume and frequency, were significantly improved in 8 follow-up patients, and 3 (3/8) of them were cured; the median symptom score decreased significantly from 11.0 before surgery to 3.0 after surgery ( P<0.001). The incidence of erysipelas was significantly reduced from 7/10 before surgery to 2/8 after surgery ( P=0.035). Conclusions:The main causes of female ALV are pelvic tumor surgery and radiotherapy. The clinical diagnosis is made from relevant medical history, clinical manifestations, LS and magnetic resonance imaging. The diagnosis is confirmed by histopathological findings. Pathological results show lymphangiectasia in the dermal papilla, and immunohistochemical staining show positive for D2-40 and negative for CD 34. The effect of staged surgery on ALV is remarkable and even cured, and could effectively reduce the incidence of erysipelas.
