Bronchial asthma （BA） is a common chronic inflammatory airway disease characterized by airway hyperresponsiveness and reversible airflow limitation. Lung macrophages （LMs）， as important effector cells of the innate immune system， play an important role in recognizing and engulfing pathogens， clearing harmful particles， and regulating immune responses. LMs can be polarized to M1 （pro-inflammatory） or M2 （anti-inflammatory） in different immune environments and participate in promoting or inhibiting inflammatory response， as well as lung parenchyma injury and repair （airway remodeling）， playing a key role in the BA occurrence and development. Regulating the polarization balance of macrophages can not only inhibit the inflammatory response in the airway and reduce airway hyperresponsiveness， but also improve airway remodeling and immune regulation， reduce airway mucus secretion， and alleviate the clinical BA symptoms. Traditional Chinese medicine and its active ingredients， especially polysaccharides and saponins， can regulate the polarization balance of M1/M2 macrophages. Traditional Chinese medicine compounds can balance the secretion of anti-inflammatory and pro-inflammatory factors by staging treatment and targeting the polarization state of M1/M2 macrophages， inhibit inflammatory response in the airway， reduce airway remodeling， and improve the BA symptoms. This paper summarized the research progress on the regulation of M1/M2 macrophage polarization by traditional Chinese medicine and its active ingredients， aiming to provide scientific evidence for the precise targeted therapy of BA.

Objective: To evaluate the efficacy of a short video based health education model in enhancing e-cigarette awareness among junior high school students, so as to provide empirical evidence for optimizing school based health education in the digital era. Methods: In December 2024, a cluster sampling method was applied to recruit 465 eighth grade students from a middle school in Kunming for a survey. The intervention was implemented through playing short videos produced by the research team in the classroom, and a self designed adolescent e-cigarette questionnaire was used to conduct assessments before and after intervention, along with qualitative interviews with 60 teachers and students by purposive sampling. Pre and post intervention outcomes were compared by using paired t-test and Chi-square test. Qualitative data underwent a three stage coding process of "open, axial, and selective coding" to construct an explanatory framework. Results: Quantitative analysis showed significant post intervention increases in both baseline awareness scores（92.1±6.6）and deep awareness scores (70.0±17.6) compared with pre intervention( 78.2± 14.0，46.1±20.5)( t =23.54，26.72，both P <0.05), both meeting the criteria for large effect sizes (Cohen s d =1.09, 1.24). The improvement in deep awareness was particularly pronounced, specifically regarding addictive ingredients, illicit additives(tiletamine,metomidate,etomidate), and misconceptions about smoking cessation efficacy ( χ 2=150.54,113.27,117.40,112.92, 69.93 , all P <0.01). Qualitative insights revealed that narrative transportation and visual enhancement were the core mechanisms of efficacy: 87.3% of students preferred contextualized narratives, 85.5% of students decoded cognitive bottlenecks more effectively because of visual enhancement, and 72.7% relied on short videos for micro learning. Conclusion Short video based health education can effectively enhance e-cigarette awareness among junior high school students, offering a pragmatically viable digital pathway for school based health education.

ObjectiveTo explore the clinical efficacy and safety of Da Chaihutang （DCH） for the treatment of sepsis with Yang syndrome. MethodsA total of 70 patients suffering from sepsis with Yang syndrome were randomly divided into an observation group and a control group， with 35 cases in each group. They both received standard Western medicine treatment. The observation group was additionally given a dose of DCH， which was boiled into 100 mL and taken twice. The control group was additionally given an equal volume and dosage of warm water. The intervention lasted for three days. The 28-day all-cause mortality and the changes in the following indicators before and after intervention were compared between the two groups， including sequential organ failure assessment （SOFA）， acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ） score，white blood cell （WBC），the percentage of neutrophils （NEU%），C-reactive protein （CRP），procalcitonin （PCT），alanine transaminase （ALT），aspartate transaminase （AST），total bilirubin （TBil），creatinine （Cr），blood urea nitrogen （BUN），acute gastrointestinal injury （AGI） grade，gastrointestinal dysfunction score （GDS），serum intestinal fatty acid-binding protein （iFABP）， citrulline （CR），platelet （PLT），prothrombin time（PT），activated partial thromboplastin time （APTT），fibrinogen （Fib），international normalized ratio （INR），and D-dimer （D-D）. ResultsThere was no significant difference between the two groups regarding 28-day all-cause mortality. After the intervention，SOFA，WBC，PCT，and Cr were significantly decreased， and PLT was significantly increased in the control group （P<0.05）. SOFA，APACHE Ⅱ，NEU%，CRP，PCT，ALT，AST，Cr，BUN，AGI grade，GDS，and serum iFABP and CR were significantly improved in the observation group （P<0.05）. After the intervention，APACHE Ⅱ，PCT，AGI grade，GDS，and serum iFABP in the observation group were significantly lower than those in the control group ，while CR and PLT were higher （P<0.05，P<0.01）. There were significant differences regarding the gap of SOFA，APACHE Ⅱ，AST，TBil，AGI grade，GDS，iFABP，CR， and PLT between the two groups （P<0.05，P<0.01）. There were slight differences regarding PT，APTT，Fib，INR，and D-D between the two groups，which were in the clinical normal range. ConclusionOn the basis of Western medicine， DCH helped to reduce sepsis severity and improved multiple organ dysfunction with high clinical efficacy and safety， but further research on its impact on the prognosis of patients with sepsis is still required.

Objective:To investigate the iodine nutrition status of children and pregnant women in different water iodine areas of Shandong Province.Methods:From February to September 2023, Leling City (iodine deficient), Gaotang County (moderate iodine), and Liangshan County (high iodine) in different water iodine areas of Shandong Province were selected as survey sites. One village was selected from each county (city) in five directions: east, west, south, north, and center. Forty children aged 8 to 10 years (balanced in age, half male and half female) and 20 pregnant women were selected as survey subjects in each village. Random urine samples of children and pregnant women were collected to test for urinary iodine. Meanwhile, thyroid examinations were conducted on children to calculate the goiter rate.Results:A total of 600 urine samples of children were tested, with a median urinary iodine level of 246.0 μg/L. The median urinary iodine levels of children in iodine deficient, moderate iodine and high iodine areas were 219.6, 208.0 and 446.0 μg/L, respectively ( n = 200, 200, 200). The median urinary iodine level of children in high iodine area was significantly higher than that in iodine deficient and moderate iodine areas ( P < 0.05). A total of 600 children underwent thyroid examinations, with a goiter rate of 5.8% (35/600). The goiter rate of children in iodine deficient, moderate iodine, and high iodine areas were 4.0% (8/200), 1.0% (2/200), and 12.5% (25/200), respectively. The goiter rate of children in high iodine area was significantly higher than that in iodine deficient and moderate iodine areas ( P < 0.05). A total of 247 urine samples of pregnant women were tested, with a median urinary iodine level of 158.2 μg/L. The median urinary iodine levels of pregnant women in iodine deficient, moderate iodine, and high iodine areas were 75.3, 175.2 and 321.2 μg/L, respectively ( n = 98, 84, 65). The median urinary iodine level of pregnant women in high iodine area was significantly higher than that in iodine deficient and moderate iodine areas, and the median urinary iodine level of pregnant women in moderate iodine area was significantly higher than that in iodine deficient area ( P < 0.05). Conclusion:The urinary iodine levels of children and pregnant women and the goiter rate of children in high iodine area of Shandong Province are significantly increased, and water iodine may be a key factor affecting the iodine nutrition status of the population.

Objective:To investigate the expression and clinical significance of non coding RNA GATA binding protein 6 antisense RNA1 (lncRNA GATA6-AS1) and GATA binding protein 6 messenger RNA (GATA6 mRNA) in ovarian cancer.Methods:A prospective study was conducted on 98 patients with ovarian cancer treated at the Second Hospital of Tianjin Medical University, from January 2022 to January 2025, and 98 patients with benign ovarian lesions during the same period were selected as the control group. Real-time quantitative polymerase chain reaction (qPCR) was used to detect the serum and tissue expression levels of lncRNA GATA6-AS1 and GATA6 mRNA in patients with ovarian cancer and benign ovarian lesions. Pearson analysis was performed to assess the correlation between serum lncRNA GATA6-AS1 and GATA6 mRNA levels in patients with ovarian cancer. Receiver operating characteristic (ROC) curves were plotted to analyze the diagnostic value of serum lncRNA GATA6-AS1 and GATA6 mRNA levels in patients with ovarian cancer.Results:Compared with the control group, the serum levels of lncRNA GATA6-AS1 and GATA6 mRNA in the study group were decreased: 0.76 ± 0.18 vs. 1.00 ± 0.22, 0.75 ± 0.19 vs. 1.01 ± 0.21, with statistically significant differences ( P<0.05). Pearson analysis revealed a positive correlation between serum lncRNA GATA6-AS1 and GATA6 mRNA levels in the study group ( r = 0.61, P<0.05). Compared with benign ovarian lesion tissues, the expression levels of lncRNA GATA6-AS1 and GATA6 mRNA in ovarian cancer tissues were reduced: 0.65 ± 0.15 vs. 1.01 ± 0.20, 0.59 ± 0.12 vs. 1.01 ± 0.24, with statistically significant differences ( P<0.05). In serous ovarian cancer tissues, the expression levels of lncRNA GATA6-AS1 and GATA6 mRNA were lower than those in mucinous ovarian cancer tissues: 0.61 ± 0.10 vs. 0.77 ± 0.16, 0.54 ± 0.11 vs. 0.74 ± 0.14, with statistically significant differences ( P<0.05). The expression of lncRNA GATA6-AS1 and GATA6 mRNA in ovarian cancer tissues was associated with tumor size, International Federation of Gynecology and Obstetrics stage, differentiation degree, lymph node metastasis, peritoneal metastasis, and ascites ( P<0.05). The ROC curve indicated that the combined diagnosis of serum lncRNA GATA6-AS1 and GATA6 mRNA for ovarian cancer had an area under the curve (AUC) of 0.905, which was significantly higher than that of lncRNA GATA6-AS1 alone ( Z = 2.45, P = 0.014) and GATA6 mRNA alone ( Z = 2.16, P = 0.031). Conclusions:The lncRNA GATA6-AS1 and GATA6 mRNA in serum and tissue of ovarian cancer patients decrease, showing a positive correlation. The joint of the two has high diagnostic value for ovarian cancer.

Objective To investigate the clinical application value of the combined detection of fecal syndecan 2(SDC2)and tissue factor pathway inhibitor 2(TFPI2)gene methylation in the diagnosis of colorectal cancer and advanced adenoma.Methods 124 pa-tients with colorectal lesions,including 43 colorectal cancer,52 advanced adenoma,and 29 non-advanced adenoma,and 46 patients with other gastrointestinal diseases such as colorectal inflammatory diseases,ulcers,etc.,who visited 5 hospitals in Zhengzhou from 2020 to 2023 were enrolled as the disease group.In addition,78 healthy individuals who underwent physical examinations in the same period were selected as the healthy control group.Their fecal samples were collected before undergoing colonoscopy,and the methyla-tion levels of SDC2 and TFPI2 genes were detected using the quantitative methylation-specific PCR(qMSP).Results The positive rates of the combined detection of SDC2 and TFPI2 gene methylation in the colorectal cancer group and advanced adenoma group(95.34％and 88.46％)were significantly higher than those in the non-advanced adenoma group(48.27％,x2=18.75/13.63,P＜0.05)and healthy controls(3.84％,x2=96.38/91.54,P＜0.05).In the colorectal cancer group,the postoperative positive rate of the combined detection in 34 patients with positive methylation of SDC2 and TFPI2(5.88％)was significantly lower than the preoperative positive rate(95.34％,x2=54.74,P＜0.05).Moreover,the mean Ct values of methylation of SDC2 and TFPI2 genes(32.38±3.72 and 31.85±3.21)in the colorectal cancer group were significantly lower than that in the advanced adenoma group(35.07±3.09 and 34.96±2.78,t=3.84 and 5.05,P＜0.05).The analysis results of the ROC curve showed that the sensitivities of SDC2,TFPI2,and their combination detection in the diagnosis of colorectal cancer were 86.40％,88.37％,and 89.35％,respectively,while in differenti-ating advanced adenoma they were 73.52％,66.73％,and 80.15％,respectively.The combined detection of SDC2 and TFPI2 in differ-entiating colorectal cancer and advanced adenoma achieved the highest diagnostic efficacy(AUCROC=0.889 and 0.738,respectively).Conclusion The combined detection of methylation of SDC2 and TFPI2 genes in fecal samples has high diagnostic value for colorectal cancer and advanced adenomas,and also has certain clinical application value for the progression and postoperative monitoring of the disease.

Objective:To investigate the effects of enolase 1(ENO1)on the proliferation,migration,and invasion of gastric cancer cells and its underlying molecular mechanisms.Methods:The expression levels of ENO1 in human gastric cancer cell lines(HGC27,MKN-45,N-87,MGC803,BGC-823)and human gastric mucosal epithelial cells(GES-1)were detected using WB assay.Gene editing tools such as CRISPR and overexpression system were used to construct ENO1 knockdown and knockdown-rescue cell lines.Both MKN-45 and BGC-823 cells were grouped into control(Ctrl)group,ENO1 knockdown(ENO1 KD)group,and ENO1 knockdown-rescue(ENO1 KD-OE)group.The effects of ENO1 knockdown or ENO1 knockdown-rescue on the proliferation,migration,invasion,and apoptosis of gastric cancer cells were evaluated using colony formation assay,EdU staining,scratch wound healing assay,Transwell chamber assay and flow cytometry.Additionally,a xenograft model was established in nude mice,and the effects of ENO1 on tumor growth were monitored using small animal in vivo imaging and tumor tissue block measurement.ENO1 was silenced in MKN-45 cells employing RNA interference technology,and the downstream target genes of ENO1 were identified using RNA co-immunoprecipitation sequencing(RIP-seq)and bioinformatics analysis.The molecular mechanisms by which ENO1 regulates the proliferation,migration and invasion of gastric cancer cells was also analyzed.Results:ENO1 was significantly upregulated in gastric cancer cell lines(P<0.01 or P<0.001).ENO1 knockdown significantly inhibited proliferation,migration,and invasion while promoting apoptosis in MKN-45 and BGC-823 cells(P<0.001,P<0.000 1).Rescue experiments showed that restoring ENO1 expression significantly enhanced cell proliferation,migration,invasion,and inhibited apoptosis(P<0.05,P<0.01,P<0.001,P<0.000 1).In vivo experiments demonstrated that ENO1 knockdown significantly inhibited tumor growth in nude mice(P<0.000 1).The differentially expressed genes interacting with ENO1 protein were primarily enriched in pathways related to RNA splicing.Additionally,ENO1 protein was found to interact with the PKM gene,and their expressions showed a positive correlation in gastric cancer tissues(r=0.886).Conclusion:ENO1 is highly expressed in gastric cancer cells.ENO1 interacts with precursor mRNA of PKM to influence its RNA splicing process,thereby regulating PKM2 expression and promoting gastric cancer progression.

Objective:To systematically evaluate the risk prediction models for refeeding syndrome in critically ill patients in China and abroad, with the aim of providing feasible risk assessment tools for clinical healthcare professionals.Methods:A computerized search of PubMed, Embase, Web of Science, Cochrane Library, CINAHL, Proquest, Scopous, China Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), Wanfang, and VIP was conducted for relevant literature from database inception to July 1, 2024. Two researchers independently reviewed the literature and extracted the relevant information. Quality assessment was performed using a risk of bias assessment tool specifically designed for predictive modeling.Results:A total of 8 papers were included, reporting 8 risk prediction models for refeeding syndrome in critically ill patients, with sample sizes ranging from 109 to 806 cases, outcome event rates from 22.5% to 69.8%, and area under the curve values from 0.74 to 0.95. The most frequently reported predictors included albumin (ALB), pre-albumin (PAB), blood potassium, use of diuretics, and Acute Physiology and Chronic Health Evaluation Ⅱ (APACHE Ⅱ) scores.Conclusions:The risk prediction models for refeeding syndrome in critically ill patients have good predictive performance but are still in the development stage. A high-quality, low-bias clinically applicable model should be established through multicenter, large-sample, and standardized studies.
