ObjectiveTo investigate the nutritional status and influencing factors among primary and secondary school students in Karamay District, Karamay City, Xinjiang in 2022, and to provide basis for improving their nutritional status. MethodsA stratified random cluster sampling method was used to monitor the nutritional status of students from two primary schools, two middle schools and two high schools in Karamay District. Data collected included age, gender, height and weight. A questionnaire survey was conducted among 1 529 students in grade 4 and above to investigate the influencing factors related to their nutritional status, such as boarding status, dietary habits, and behavioral patterns. ResultsAmong the 1 529 students, the detection rate of malnutrition was 3.31%, among which the detection rates of growth retardation, moderate to severe emaciation and mild emaciation were 0.52%, 0.72%, and 2.09%, respectively. The detection rate of over nutrition was 45.91%, with overweight and obesity rates of 20.80% and 25.11%, respectively. The results of univariate analyses showed that statistically significant differences were observed in the detection rates of mild emaciation, overweight, obesity and over nutrition across different genders (all P<0.05). Statistically significant differences were also exhibited in the detection rates of moderate to severe emaciation, obesity and over nutrition across different age groups (all P<0.05). In addition, statistically significant differences were also found in the detection rates of obesity and over nutrition across boarding status and the frequency of consuming fish, poultry, meat, and eggs at breakfast (all P<0.05). Students with different vegetable consumption frequencies showed significant differences in obesity prevalence (χ²=8.826, P=0.032), while those with varying fried food intake frequencies differed significantly in growth retardation prevalence (χ²=4.511, P=0.034). The results of logistic regression analyses revealed that the risks of overweight and obesity for boys were 1.55 and 2.32 times higher than that for girls, respectively (all P<0.05). Students within 13‒<16 years age group had 1.43 and 1.38 times higher risks of malnutrition and obesity compared to those with 6‒<13 years age group, respectively (all P<0.05). Boarding students had 0.49, 1.12, and 1.13 times higher risks of malnutrition, overweight, and obesity, respectively, compared to non-boarding students (all P<0.05).Students with breakfast including meat,fish and eggs daily had 0.58, 0.80, and 0.40 times lower the risk of malnutrition, overweight, and obesity, respectively, compared to those whose breakfast didn’t include meat, fish and eggs (all P<0.05). Students with low consumption of sugar-sweetened beverages and fried foods had 0.63 and 0.64 times lower the risk of overweight, respectively, compared to those with high consumption. Students with low fresh fruit intake frequency had 1.31 and 1.39 times higher the risk of malnutrition and overweight, respectively, compared to those with high intake frequency (all P<0.05). Students with less vegetable consumption had 1.45 and 1.40 times higher the risk of malnutrition and obesity, respectively, compared to those with more consumption of vegetables (all P<0.05). Students who engaged in moderate to vigorous physical activity (MVPA) ≥60 min/day for 1‒3 days/week and those who did not engage in MVPA had 1.11 and 1.17 times higher the risk of obesity, respectively, compared to those who engaged in MVPA ≥60 min/day for 4‒7 days/week (all P<0.05). Students who met daily sleep duration recommendations had 0.78, 0.67, and 0.72 times lower the risk of malnutrition, overweight, and obesity, respectively, compared to those who did not. ConclusionOverweight and obesity are prominent nutritional issues among primary and secondary school students in Karamay District. Age and dietary habits are strongly associated with overweight and obesity. Boys and non-boarding students need particular attention. Targeted interventions focusing on balanced diets and physical activity should be implemented promptly, along with enhanced nutrition education to promote healthy lifestyles. Personalized intervention strategies should be developed based on age and gender to improve the nutritional status of primary and secondary school students in Karamay District.

Objective:To investigate factors influencing frequent episodes (≥ 4 episodes within 1 year) in children with moderate-to-severe atopic dermatitis (AD) in China.Methods:A national multicenter cross-sectional study was conducted. Patients under the age of 18 years diagnosed with moderate-to-severe AD were enrolled at dermatology clinics in 18 medical institutions across 12 provinces and municipalities in China between June 12 and August 8, 2023. At the time of the visit, their guardians completed a structured questionnaire covering demographic characteristics, clinical features of AD, personal and family history, factors associated with frequent episodes of moderate-to-severe AD, compliance with treatment, and disease awareness. Statistical analyses included t tests, one-way analysis of variance, rank-sum tests, and chi-square tests, with multiple-response analysis applied for multiple-choice questions. Results:A total of 965 valid questionnaires were collected, and 965 children with moderate-to-severe AD were included. Among them, there were 531 males and 434 females, 678 (70.3%) were aged 2 - < 12 years, 837 (86.7%) were from urban areas, the age at onset was 2.47 ± 3.03 years, and the median frequency of AD episodes in the past year was 4 times. These children were divided into 2 groups based on the median episode frequency: < 4-episode group (439 cases, 45.5%) and ≥ 4-episode group (526 cases, 54.5%). Compared with the < 4-episode group, children in the ≥ 4-episode group showed younger ages at onset (2.22 ± 2.98 years vs. 2.76 ± 3.06 years, P = 0.006) and higher proportions of patients with comorbid allergic diseases in both the children themselves (82.9% [436/526] vs. 69.7% [306/439], χ2 = 23.42, P < 0.001) and their relatives (66.0% [347/526] vs. 57.4% [252/439], χ2 = 7.46, P = 0.006). Children in the ≥ 4- episode group also had higher monthly usage of moisturizers (150 [30, 300] g vs. 60 [6, 200] g) and daily frequency of moisturizer use, greater disease awareness, but more severe fear of medication use (all P < 0.05). The region and the human development index level were both significantly associated with the episode frequency (both P < 0.001), with the highest proportion of children from South China in the ≥ 4- episode group (36.3%, 191/526). Children in the ≥ 4-episode group also had a longer duration of topical glucocorticoid use than those in the < 4-episode group ( Z = -2.21, P = 0.027). External triggers associated with AD episodes mainly included heat exposure (50.36%, 486/965), hot water bathing (40.73%, 393/965), seafood (23.52%, 227/965), and dust mites (33.37%, 322/965) . Conclusion:In children with moderate-to-severe AD in China, factors influencing frequent episodes may include residence in southern or economically developed regions, earlier age at onset, having a personal or family history of allergic diseases, and fear of medication use.

Objective To investigate the sputum metabolic profiles of patients with occupational coal workers' pneumoconiosis (CWP) by an untargeted metabolomics method, and to identify relevant differential metabolic pathways and potential biomarkers. Methods A total of 12 male patients with stage Ⅰ CWP were selected as the CWP group, and 16 healthy male individuals were selected as the control group, using a judgmental sampling method. Sputum metabolites of individuals in both groups were detected to perform non-targeted metabolomic analysis using the ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry. Differential metabolites (DMs) and their pathways were screened using principal component analysis, partial least squares discriminant analysis, and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis. Potential biomarkers were analyzed and identified via the receiver operating characteristic curve (ROC). Results There were apparent metabolic alterations observed in sputum of CWP patients compared with healthy controls. In the positive ion mode, a total of 42 DMs were identified in sputum from CWP patients, including 19 downregulated and 23 upregulated metabolites. In the negative ion mode, a total of 25 DMs were identified in sputum from CWP patients, including 16 downregulated and 9 upregulated metabolites. KEGG enrichment analysis of sputum from CWP patients showed that seven DMs pathways were enriched in ABC transporters, histidine metabolism, phenylalanine metabolism, arachidonic acid metabolism, linoleic acid metabolism, purine metabolism, and oxidative phosphorylation, involving 26 DMs. ROC analysis indicated that 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate of these 26 DMs may serve as potential biomarkers for CWP. Conclusion Sputum metabolomic profiles were altered in CWP patients compared with healthy controls. The potential biomarkers of CWP prevention and treatment are 16(R)-hydroxyarachidonic acid, pyrophosphate, and 2-hydroxyphenylacetate.

Objective:To develop a nomogram model for screening of type 2 diabetes mellitus in a community population.Methods:From October to December, 2020, 6 028 community residents who participated in the " national health physical examination" in Karamay community with complete physical examination data and met the inclusion and exclusion criteria were selected. The physical examination data included medical history, physical examination, laboratory, and ultrasound reports. Random segmentation sampling was used to divide the population into modeling and validation cohorts, and LASSO regression analysis was used to screen for independent factors associated with diabetes diagnosis. The independent influencing factors were furthor incorporated into the multi-factor logistic regression, and the RMS software package was used to construct the column chart. The area under receiver operating characteristic(ROC) curve was used to measure the differentiation of the model. The calibration curve can directly reflect the calibration degree of the model.Results:In the modeling group, multivariate logistic regression analysis showed that age, gender(female), history of hypertension, history of hyperlipidemia, HbA 1C, urinary microalbumin, homeostasis model assessment for insulin resistance, and triglycerides and glucose index were independently associated with diabetes. OR were 1.053(95% CI 1.038-1.069), 0.681(95% CI 0.512-0.906), 1.802(95% CI 1.227-2.626), 1.789(95% CI 1.303-2.448), 10.973(95% CI 8.318-14.745), 1.002(95% CI 1.001-1.004), 2.914(95% CI 2.248-3.799), and 2.673(95% CI 2.03-3.536), respectively. The areas under ROC curves of the training set and the validation set were 0.945 and 0.955, respectively. The optimal critical value in the ROC curve was 0.178(sensitivity 0.930, specificity 0.839) in the training set and 0.201(sensitivity 0.945, specificity 0.848) in the validation set. Conclusion:The screening model of type 2 diabetes developed in this study has good accuracy, which can be used as a screening tool for high-risk population of type 2 diabetes.

Objective:To evaluate clinical efficacy and safety of topical compound oleum lithospermi in the treatment of mild to moderate diaper dermatitis.Methods:A multicenter, randomized, positive-drug parallel-controlled clinical trial was conducted in 19 hospitals from July 2019 to August 2020. Children aged 0 - 12 months with mild to moderate diaper dermatitis were enrolled and randomly divided into 2 groups using a random number table: test group topically treated with compound oleum lithospermi, and control group topically treated with zinc oxide cream. The treatment was carried out 6 - 8 times a day for 7 days. Visits were scheduled on days 0 and 7, and total response rate and clinical healing time were evaluated. Changes in the dermatitis family impact (DFI) score were compared between the test group and control group, and adverse events were recorded. Statistical analysis was carried out by using independent-sample t test for normally distributed continuous data, Wilcoxon rank sum test for non-normally distributed continuous data, and chi-square test or Fisher′s exact test for unordered categorical data; survival curves were drawn, and log-rank test was used for comparisons between two groups. Results:A total of 343 children with diaper dermatitis were enrolled in this study. Among them, 31 children violated the protocol, so 312 were included in the per protocol set, including 157 in the test group and 155 in the control group, and all completed the visits on days 0 and 7. The total response rate was significantly higher in the test group (87.26%, 137/157) than in the control group (78.71%, 122/155; χ2 = 4.04, P = 0.044) . The clinical healing time was significantly shorter in the test group (5.33 days) than in the control group (6.13 days; χ2 = 4.67, P = 0.025) . After 7-day treatment, the DFI score significantly decreased in both the 2 groups compared with that before the treatment, but there was no significant difference in the DFI score between the 2 groups (test group: 4.02 ± 6.96, control group: 3.58 ± 5.90, Z = -0.39, P = 0.686) . The incidence of adverse events was 2.92% (5/171) and 5.45% (9/165) in the test group and control group respectively, and there was no significant difference between the 2 groups ( χ2 = 0.03, P = 0.865) . Conclusion:Compound oleum lithospermi can markedly reduce the clinical severity of diaper dermatitis, improve the total response rate, shorten the clinical treatment period, and improve the quality of life of children′s families with a favorable safety profile.

OBJECTIVE To monitor the occurrence of tenofovir disoproxil fumarate （TDF）-induced kidney injury and investigate the risk factors， and provide reference for rational use of TDF in clinic. METHODS The information of inpatients with hepatitis B was collected by China Hospital Pharmacovigilance System （CHPS） from the Second People’s Hospital of Lanzhou during Jan. 1st， 2019 to Dec. 31st 2021. The search criteria were set according to kidney injury criteria， and suspected TDF- induced kidney injury cases were actively monitored； then the clinical pharmacist confirmed the positive patients with TDF-induced kidney injury one by one and calculated the incidence of TDF-induced renal injury； the risk factors for TDF-induced kidney injury in real world were explored by collecting and analyzing the correlation of basic data of patients， main indexes of liver and kidney function， complications and combined use of drugs with TDF-induced renal indexes. RESULTS Totally 1 226 inpatients with hepatitis B using TDF were included. Through active monitoring of CHPS， 160 suspected patients with TDF-induced kidney injury were found， and 64 positive patients were finally confirmed manually. The incidence of TDF-induced kidney injury was 5.22%. Compared with pre-medication， the levels of serum creatinine and cystatin C， the proportion of patients with urinary protein 2+ and above were increased significantly after medication （P＜0.001）， glomerular filtration rate and blood phosphorus level were reduced significantly （P＜0.001） and other indicators had no statistical difference. Treatment time for more than 36 months， disease progresses to decompensated cirrhosis， and concomitant use of more than 10 kinds of drugs were significantly correlated with TDF- related kidney injury （P＜0.05 or P＜0.012 5）. CONCLUSIONS The active monitoring scheme of TDF-induced kidney injury established by CHPS has the characteristics of time-saving， labor-saving and high efficiency； based on real-world evidence， it is imperative to strengthen monitoring kidney function of patients when using TDF， especially when the patient has been on medication for a long time， in decompensated cirrhosis and combination of multiple drugs， and thus， we can identify earlier and avoid adverse effects in high-risk patientseffectively.

Objective:To explore the effect of supportive-expressive group therapy (SEGT) on alexithymia in patients with lung cancer.Methods:Totally 62 lung cancer patients were divided into control group( n=30) and intervention group( n=32) by coin flipping method.The intervention group received 6-week supportive-expressive group therapy and the intervention path was improved by action research method.There was no special intervention in the control group.The Toronto alexithymia scale (TAS-20) and hospital anxiety and depression scale (HADS) were used for measurement, and statistical analysis was carried out by SPSS 21.0. Results:The emotional recognition disorder (Wald groupχ 2=6.055, Wald interactionχ 2=15.157), emotional description disorder (Wald groupχ 2=5.736, Wald interactionχ 2=28.912), TAS-20 (Wald groupχ 2=7.181, Wald interactionχ 2=28.126), anxiety (Wald groupχ 2=4.905, Wald interactionχ 2=30.491), depression (Wald groupχ 2=9.580, Wald interactionχ 2=29.417) and HADA (Wald groupχ 2=8.140, Wald interactionχ 2=47.851) had significant group effect and interaction effect at the pre-test, post-test and 1 month after intervention(all P<0.05). There was no significant group effect in extroverted thinking (Wald groupχ 2=1.161, P>0.05), but the time effect (Wald timeχ 2=6.381, P<0.05) and the interaction effect (Wald interactionχ 2=6.339, P<0.05) were significant in the three time points.The group effect of emotional recognition disorder, emotional description disorder, TAS-20, anxiety, depression and HADA score at completed intervention and 1 month after intervention were significant(all P<0.05). Compared with before intervention, TAS-20((52.94±4.77) , (52.06±4.07)), emotional recognition disorder((17.72±2.23) , (17.78±1.64)), emotional description disorder((13.44±1.94) , (13.41±1.79)), HADA((14.41±2.63) , (13.75±2.97)), anxiety ((7.03±1.64), (6.84±1.51)), depression ((7.38±1.45) , (6.91±1.75) ) at completed intervention and 1 month after intervention decreased ( P<0.05), while the HADS of control group only decreased at completed intervention ( P<0.05). Conclusion:SEGT can reduce alexithymia in lung cancer receiving chemotherapy, and this intervention has positive effect on improving anxiety and depression in lung cancer patients received chemotherapy who are accompanied with emotional cognitive impairment and emotional somatic symptom recognition disorder.
