Chinese Journal of School Health 2025;46(6):888-893
Objective:
To explore the association between CDKAL1 rs35261542, FAIM2 rs 3205718, and VGLL4 rs 2574704 polymorphisms with childhood obesity and related metabolic phenotypes to provide evidence for personalized prevention and management strategies.
Methods:
Based on the 2023 Long term Nutritional Health Effects of Early Childhood Nutrition Package Intervention project, the study enrolled 1 078 children aged 5-7 years from four counties in Henan (Songxian and Ruyang countries) and Guizhou (Guiding and Fuquan countries) provinces. Using BMI Z scores, 87 overweight and obese(OVOB) children were selected and matched by sex, age, and BMI Z score with 117 normal weight controls. Participants were further stratified into four metabolic phenotype groups: metabolically healthy normal weight (MHNW, n =51), metabolically unhealthy normal weight (MUNW, n =66), metabolically healthy obesity (MHO, n =31) and metabolically unhealthy obesity (MUO, n =56) based on four conventional cardiometabolic risk factor (CR) criteria. Data were collected through questionnaires, anthropometric measurements, serum biochemical tests, and KASP genotyping. The distribution of three genetic polymorphisms ( CDKAL1 rs35261542, FAIM2 rs3205718, VGLL4 rs 2574704) across metabolic subgroups was analyzed. Multivariate Logistic regression models assessed associations between these polymorphisms and obesity/metabolic phenotypes.
Results:
Multivariate Logistic regression analysis showed that Homozygous mutant AA genotype of CDKAL1 rs 35261542 was positively associated with OVOB( OR =3.63), MHO ( OR =11.04), MUO ( OR = 4.88 ) ( P <0.05). Homozygous TT genotype of FAIM2 rs 3205718 increased OVOB risk ( OR =4.44, P <0.05) but showed no association with metabolic phenotypes ( P >0.05). Homozygous mutant TT of VGLL4 rs 2574704 reduced the risks of MHO and MUO ( OR = 0.30, 0.24, P <0.05). Cumulative genetic effects analysis demonstrated carriers of 1 or 2 risk genotypes of rs 35261542 and rs 3205718 had progressively higher OVOB risk ( OR =2.53, 20.79), and the combination of rs 35261542 and rs 2574704 increased risks for both MHO ( OR =8.50) and MUO ( OR =5.00) ( P <0.05).
Conclusions
The AA genotype of rs 35261542 ( CDKAL1 ) positively correlates with childhood obesity and metabolic abnormalities. The TT genotype of rs 3205718 ( FAIM 2) increases obesity risk but not metabolic phenotypes. The TT genotype of rs 2574704 ( VGLL 4) shows protective effects against metabolic dysfunction. Risk genotypes exhibit dosedependent cumulative effects on obesity and metabolic outcomes.

Sepsis is one of the common severe diseases caused by the dysregulated host response to infection, which seriously threatens the life and health of human beings all over the world. The incidence and mortality of the disease are extremely high, and it has always been an urgent problem to be solved in the field of acute and critical diseases. At present, anti-infection, fluid resuscitation, mechanical ventilation and other programs are most used in clinic to treat sepsis, but their poor prognosis and high cost and other issues remain to be resolved. Therefore, it is necessary to explore a new, efficient, safe and inexpensive drug and treatment model at this stage. The treatment of traditional Chinese medicine (TCM) is based on syndrome differentiation and holistic concept. It can effectively regulate the progression of sepsis, maintain the homeostasis of the body, and has fewer adverse reactions. It has achieved good clinical results. In recent years, a large number of studies have shown that TCM can reduce the inflammatory response by regulating the Toll-like receptor 4(TLR4) signaling pathway, thereby reducing the severity and mortality of sepsis patients. However, there is still a lack of systematic exposition of TCM regulating TLR4 signaling pathway in the treatment of sepsis. Therefore, this article summarizes the relationship between TLR4 signaling pathway and sepsis and the mechanism of TCM in the disease by searching and consulting relevant literature in recent years. It is found that some Chinese medicine monomers and active ingredients, Chinese medicine compounds and Chinese medicine preparations can effectively reduce systemic inflammatory response, repair organ damage and improve the prognosis of sepsis by inhibiting the activation of TLR4 signaling pathway. However, due to various limitations, some studies have directly focused on the differential expression and function of TLR4, ignoring the downstream molecular expression and phenotypic effects of TLR4. The alternative mechanism, relationship and specific molecular mechanism of the pathway are still unclear. There are problems such as unclear pharmacokinetics and unclear mechanism in the pro- and anti-inflammatory balance, which need to be further studied and explored in order to provide new ideas for the potential treatment and drug development for sepsis.

Gastroesophageal reflux disease (GERD) is a gastrointestinal motility disorder characterized by the reflux of gastric contents into the esophagus, leading to symptoms such as acid reflux and heartburn. The incidence of GERD is closely associated with psychological disorders, including anxiety and depression. The brain-gut axis, serving as a mediator of the bidirectional connection between the brain and the gastrointestinal tract, plays a crucial role in the occurrence and development of GERD with anxiety and depression. Various therapeutic approaches, including compound Chinese medicine internal therapy (such as Pingchong jiangni decoction, Tiaozhong huashi decoction, etc.), combination therapy of internal and external Chinese medicine (such as Lianzhi xiere decoction combined with acupoint application, acupuncture at the back segment of governor vessel plus Chinese medication of soothing the liver and gallbladder, etc.), and combination therapy of internal Chinese and western medicine (including Jianpi shugan decoction combined with rabeprazole, rabeprazole combined with Jianzhong jiangni decoction, etc.), have been shown to regulate brain-gut peptides, intestinal flora, inflammatory factors and gastrointestinal hormones, thereby effectively alleviating GERD symptoms, anxiety and depression, and enhancing patients’ quality of life.

Objective:
To explore the association between parental myopia and extracurricular activities before school age with myopia among lower grade students, so as to provide evidence for myopia prevention on low grade students.
Methods:
From November 2020 to June 2022, a total of 8 368 students of grade 1-3 were selected from Beijing, Liaoning, Zhejiang, Henan, Chongqing, Shaanxi Province by the stratified cluster random sampling and probability sampling methods, and were administered with a questionnaire survey and eye examinations. Multivariate Logistic regression was used to analyze the association between parental myopia and extracurricular activities before school age with myopia among lower grade students.
Results:
The prevalence of myopia in grade 1-3 was 23.7% in 6 provinces in China. Students who in central area, grade 3, boarding at school, doing homework/reading/writing time ≥1 h/d after school, extracurricular activities ≥1 h in the past week, extracurricular activities before school age, parental myopia, poor reading and writing posture, sleeping time <10 h/d, less exercise time because of homework or extracurricular activities, having annual vision examination had a higher myopia detection rate, with statistically significant differences ( χ 2=36.41, 487.72, 15.97, 21.35, 43.95, 15.33, 54.04, 6.67, 3.88, 20.02, 20.06, P <0.05). After adjusted for the confounding factors, there was a significant interaction between parental myopia and extracurricular activities before school age with myopia ( P interaction <0.01). After adjusting for confounding factors, Logistic regression analysis showed that those having extracurricular activities before school age had a higher risk of myopia ( OR=1.33, 95%CI =1.19-1.56), compared with those who did not. Compared with children without nearsighted parents, children with nearsighted parents had higher prevalence of myopia ( OR=1.64, 95%CI = 1.45- 1.84) ( P <0.05); and the values of indicators ( RERI, API, Index S ) for interaction between parental myopia and extracurricular activities before school age were 0.35, 0.27, 1.37, respectively.
Conclusion
Both parental myopia and extracurricular activities before school age are associated with myopia among lower grade students, with interactive effects.

ObjectiveTo investigate the mechanism of neferine(Nef) in promoting vascular regeneration against cerebral ischemia through modulation of mitochondrial calcium uniporter(MCU) ion channel. MethodTaking the area of subintestinal vessels in microvascular deficiency zebrafish as an index, the vascular regenerative efficacy of Nef was evaluated, and the median effective concentration(EC50) was calculated. Rats were randomly divided into a sham operation group, a model group, a positive drug group(butylphthalide, 6 mg·kg-1), and Nef low, medium, and high dose groups(0.125, 0.625, 3.125 μg·kg-1). Except for the sham operation group, the middle cerebral artery occlusion(MCAO) model was established in other groups. After modeling, the groups were administered the corresponding dose of drugs by gavage, while the sham operation and model groups received equal volumes of saline, once a day for 7 consecutive days. Neurobehavioral scores were assessed for each group of rats, and the infarct rate of ischemic brain tissue was calculated by 2,3,5-triphenyltetrazolium chloride(TTC) staining. The regional cerebral blood flow(rCBF) of each group was measured using a speckle contrast imaging. Immunofluorescence and Western blot were conducted to detect the expression of vascular endothelial growth factor(VEGF), platelet endothelial cell adhesion molecule-1(CD31), and hypoxia-inducible factor-1α(HIF-1α) proteins in each group. Human umbilical vein endothelial cells(HUVECs) were divided into the normal group, model group, positive drug group(astragaloside Ⅳ, 10 μmol·L-1), and Nef group (32 nmol·L-1). In the verification of mitochondrial protection of Nef and its mechanism in promoting vascular regeneration, the spermine(MCU agonist) and Nef+spermine group were added. HUVECs model of oxygen-glucose deprivation(OGD) was established in all groups except the normal group, the cell viability was assessed using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide(MTT) assay, and cell migration ability was evaluated through scratch and tube formation assays. Fluorescent probes(Rhod-2 AM, Fluo-3 AM, JC-1, Calcein AM) and a cellular energy metabolism analyzer were used to analyze the mitochondrial protective effects of Nef. Molecular docking was performed to predict the binding ability of Nef with MCU and HIF-1α, and Western blot was used to detect the effects of Nef on the protein expressions of MCU, B-cell lymphoma-2 associated X protein(Bax), Caspase-3 and HIF-1α in the OGD model HUVECs. ResultThe results of vascular regeneration in microvascular deficiency zebrafish showed that compared to the normal group, the area of subintestinal vessels in the model group significantly decreased(P<0.01). Compared to the model group, different concentrations of Nef could significantly increase the area of subintestinal vessels(P<0.01), with the maximum tolerated concentration of 10.24 μmol·L-1 and the EC50 of 0.23 μmol·L-1. Anti-cerebral ischemia results on MCAO rats showed that compared to the sham operation group, the model group had a significant decrease in rCBF and a significant increase in infarct rate, while CD31 expression significantly decreased(P<0.01), and VEGF and HIF-1α protein expressions significantly increased(P<0.05). Compared to the model group, the treated groups showed significant increases in rCBF, significant reductions in infarct volume, and significant increases in CD31, VEGF, and HIF-1α protein expression(P<0.01). Cell experiment results showed that compared to the normal group, the model group had decreased cell viability and migration ability, increased intracellular Ca2+ and mitochondrial Ca2+ levels, reduced mitochondrial permeability transition pore(MPTP) opening, and decreased mitochondrial energy metabolism capability, with increased expressions of MCU, Bax, Caspase-3 and HIF-1α proteins(P<0.05, P<0.01). Compared to the model group, the Nef group showed increased cell viability and migration ability, decreased intracellular Ca2+ and mitochondrial Ca2+ levels, increased MPTP opening, enhanced mitochondrial energy metabolism capability, decreased expressions of MCU, Bax and Caspase-3 proteins, and increased HIF-1α protein expression(P<0.05, P<0.01). ConclusionNef can stabilize mitochondrial membrane potential and inhibit mitochondrial apoptosis. By down-regulating the expression of MCU, it suppresses the activation of intracellular Bax and Caspase-3 while activating the HIF-1α signaling pathway, enhancing the expression of VEGF and CD31, thereby promoting vascular regeneration to treat ischemic brain injury.

Objective:To analyze the clinical value of dynamic electrocardiogram combined with serum brain natriuretic peptide (BNP) and creatine kinase isoenzyme (CK-MB) levels in evaluating the severity of respiratory tract infection complicated with viral myocarditis.Methods:A total of 125 patients with respiratory tract infection who were admitted to the Affiliated Run Run Shaw Hospital of Medical School, Zhejiang University from January 2018 to December 2022 were selected retrospectively. They were divided into the complication group (71 cases) and the non-complication group (54 cases) according to whether they were complicated with viral myocarditis. Dynamic and conventional electrocardiogram characteristics were compared. Serum BNP and CK-MB levels in the complication group and the non-complication group at admission were analyzed. Dynamic electrocardiograms and serum BNP and CK-MB levels of patients with different severity of myocarditis were comparatively analyzed. The value of combined diagnosis was analyzed.Results:The detection rates of atrial premature beats and sinus tachycardia by dynamic electrocardiogram were higher than those by conventional electrocardiogram: 38.03% (27/71) vs. 22.54% (16/71), 28.17% (20/71) vs. 14.08% (10/71) ( P<0.05). Serum BNP and CK-MB levels in the complication group were higher than those in the non-complication group: (104.26 ± 10.75) ng/L vs. (54.11 ± 5.69) ng/L, (17.89 ± 1.86) U/L vs. (13.46 ± 1.42) U/L ( P<0.05). The detection rates of atrial premature beats, sinus tachycardia, burst ventricular tachycardia, first-degree atrioventricular block, ST segment change and low QRS voltage, serum BNP and CK-MB levels in patients with respiratory tract infection complicated with severe viral myocarditis (37 cases) were higher than those in patients with mild viral myocarditis (34 cases): 51.35% (19/37) vs. 23.53% (8/34), 43.24% (16/37) vs. 11.76% (4/34), 32.43% (12/37) vs. 11.76% (4/34), 29.73% (11/37) vs. 8.82% (3/34), 43.24% (16/37) vs. 14.71% (5/34), 24.32% (9/37) vs. 5.88% (2/34), (107.19 ± 10.56) ng/L vs. (101.08 ± 10.18) ng/L, (18.33 ± 1.85) U/L vs. (17.41 ± 1.76) U/L ( P<0.05). Compared with clinical pathological diagnosis, Kappa values of dynamic electrocardiogram, BNP at admission, CK-MB at admission and combination of the three for diagnosing acute upper respiratory tract infection complicated with viral myocarditis were 0.784, 0.765, 0.733 and 0.879. The sensitivity and accuracy of combined diagnosis were higher. Conclusions:Dynamic electrocardiogram combined with serum BNP and CK-MB can better help to evaluate the severity of respiratory tract infection complicated with myocarditis. Therefore, they are worthy of monitoring.

Objective:To analyze the eye lens dose and annual effective dose to interventional radiation workers in some hospitals of Xinxiang city from 2020 to 2022, and to ascertain the dose to interventional radiation workers.Methods:By using TLDs, the eye lens dose Hp(3) and annual effective dose Hp(10) were monitored for three consecutive years in six hospitals in Xinxiang city. The lens doses and annual effective doses to intervention radiation workers in different years in different-level hospitals and departments were analyzed. Results:From 2020 to 2022, a total of 117 people were monitored. The left eye lens dose range was 0.12-164.24 mSv, and the right eye lens dose range was 0.07-51.64 mSv. The average annual dose was 8.56 mSv for left eye lens and 4.49 mSv for right eye lens The average annual dose distribution in the MDL-5 mSv range for the left and right eye lens was 60.68% and 73.50%, respectively. 9.41% (11 people) of the left eye lens doses exceeded 20 mSv. The annual effective doses range was 0.11-31.27 mSv, with average annual dose of 2.56 mSv. The proportion of average annual effective doses mainly distributed in the range of MDL to 1.25 mSv was 52.14%, with 2.56% annual effective dose exceeding 20 mSv. There was no significant difference in left and right eye lens dose and annual effective dose between the tertiary hospitals and the secondary hospitals in three years ( P>0.05). Compared with different departments, the cumulative per capita dose in three years was statistically significant (left eye H=11.42, right eye H=13.72, annual effective dose H=25.94, P<0.05). The lens dose and annual effective dose in neurology department were lower than those in cardiology department and comprehensive intervention department ( Zcardiology department=-3.33, -3.78, -4.83, P<0.05; Zcomprehensive intervention department=-2.71, -2.63, -4.39, P<0.05). Conclusions:Most of the annual equivalent dose and annual effective dose to eye lens of the interventional radiation workers in Xinxiang city meet the national limits, but some of them have higher doses and exceed the national limits. It is suggested that the routine and continuous monitoring of eye lens doses to interventional radiologists should be strengthened while routine monitoring of annual effective dose, and attention should be paid to the eye lens and annual effective dose to interventional radiologists in secondary hospitals to improve the awareness of protection.

Acute pancreatitis (AP) is one of the most clinically common acute digestive disorders characterized by quick onset,rapid progression,severe condition,and high mortality. If the disease is not timely intervened in the early stage,it can develop into severe AP in the later stage,which damages the long-term quality of life and brings serious economic burden to patients and their families. However, the pathogenesis of this disease is complex and has not been fully explained. The generation and development of AP is closely related to many signaling pathways. Among them,Toll-like receptor 4(TLR4),as a transmembrane signal transduction receptor,can mediate immune response and inflammatory response,and play a key role in the occurrence and development of AP. Traditional Chinese medicine(TCM)can regulate the TLR4 signaling pathway with multiple targets,multiple effects,and multiple administration methods to inhibit inflammatory response,and effectively intervene in the progression of AP, which has gradually become a new craze for preventing and treating AP. Many studies have shown that TCM has obvious advantages in the prevention and treatment of AP. It can effectively treat AP by regulating TLR4 signaling pathway,strengthening immune resistance and defense,and inhibiting inflammatory response. Despite of the research progress,there is still a lack of comprehensive review on TCM regulation of TLR4 signaling pathway in the treatment of AP. Therefore,the literature on TCM regulation of TLR4 signaling pathway published in recent years was systematically reviewed and elaborated,aiming to provide new ideas for the treatment of AP and further drug development.

ObjectTo explore the risk factors related to the intensity of post-stroke depression in patients with cerebral infarction during hospitalization in the rehabilitation department. MethodsThe hospital consultation records of cerebral infarction patients in Beijing Bo'ai Hospital from December, 2019 to February, 2023 were reviewed from the hospital information system, and those who were diagnosed as depression visited the department of psychology were selected. It was collected including general information of sexes, ages, education levels, matrimony; medical features of course, location, affected side, sensory disorders, aphasia, agrypnia, dysphagia, hand-shoulder syndrome, constipation; functioning of muscle strength and Brunnstrom stages; and scores of Mini-Mental State Examination (MMSE), National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Fugl-Meyer Assessment-Balance (FMA-B), modified Barthel Index (MBI) and Hamilton Depression Scale (HAMD). Patients with HAMD scores ≤ 20 were as the low group, and those > 20 were as the high group. ResultA total of 2 403 hospitalized stroke patients were included, out of which 269 patients with cerebral infarction were diagnosed as depression and visited the department of psychology; while 103 cases were in the low group and 166 cases were in the high group. The incidence of constipation was less, and the incidence of dysphagia and shoulder-hand syndrome was higher in the high group (χ2 > 5.379, P < 0.05), with weaker strength of iliopsoas muscle and quadriceps muscle, earlier of Brunnstrom stage of lower extremities and hands, and worse scores of NIHSS, MMSE, FMA, FMA-B and MBI (|Z| > 2.020, t > 2.171, P < 0.05). Logistic regression showed that constipation (OR = 0.435), quadriceps muscle strength (OR = 0.782) and dysphagia (OR = 2.602) related to the intensity of post-stroke depression in convalescent patients (P < 0.05). ConclusionPost-stroke dysphagia and poor quadriceps muscle strength may exacerbate post-stroke depression; however, constipation may not.
