Objective: To explore the early effects of birth weight at different gestational ages on blood pressure trajectory among primary school students, so as to provide evidence for incorporating gestational age birth weight into individualized early warning and intervention strategies for childhood hypertension. Methods: From May to November 2023, a purposeful sampling method was used to recruit 1 676 students in grade 1-3 from three primary schools in a certain urban district of Chongqing. Follow up assessments were conducted in May 2024(T1), November 2024(T2), and May 2025(T3). General demographic and birth related information were collected via self administered questionnaires, while height, weight and blood pressure were obtained through physical examinations. Linear mixed effects model was used to analyze the associations between birth weight at different gestational ages and blood pressure trajectories. Results: During the T1-T3 period, the systolic blood pressure of boys were 98.5 (93.0, 104.5 ),98.5 (93.5, 105.0), and 97.5 (92.5, 103.5)mmHg, respectively, while the diastolic blood pressure were 60.5 (56.5, 65.0), 61.5 ( 57.0 , 65.5), and 60.0 (56.0, 64.0)mmHg, respectively. For girls, the systolic blood pressure were 95.5 (90.0, 102.0),95.5 (90.5, 101.5), and 96.0 (90.5, 101.5)mmHg, respectively, and the diastolic blood pressure were 60.5 (56.0, 64.5 ),61.5 (57.5, 65.5), and 59.5 (56.0, 63.0)mmHg, respectively. Through Friedman test within both boys and girls, diostolic blood pressure were statistically significant across three measurements( χ 2=48.85，81.54，both P <0.01). The proportion of normal blood pressure increased , and the proportion of prehypertension and hypertension decreased with time( χ 2=39.72，25.62，both P < 0.01 ). Linear mixed effects model analysis revealed that after adjusting for age, sex, household income monthly, parental education, family history of hypertension and maternal pregnancy complications, large for gestational age had significantly higher trajectories of systolic ( β = 1.50) and diastolic( β =0.94) blood pressure compared to appropriate for gestational age(both P <0.01). Conclusion Large for gestational age is associated with elevated blood pressure trajectories during school age, and it may be considered as an early indicator for individualized screening and intervention for childhood hypertension.

Objective: To systematically evaluate the effects of postnatal cadmium exposure on children s pubertal and physical development, so as to provide reference for the latter research on cadmium exposure. Methods: A computer search of PubMed, EBSCO, Web of Science, OVID, CNKI, WanFang, VIP and CBM database were conducted to collect relevant studies, and the search period was from the time of database construction to 27 February 2024. Two reviewers independently screened the literature, extracted data and evaluated the risk of bias of the included studies, and used GRADE to assess the certainty of the evidence for each outcome. Meta analysis of the risk ratio (HR) for the occurrence of menarche was performed using Stata 17.0 software, and the results were summarized qualitatively for other indicators. Results: A total of 6 cohort studies were included, comprising four pubertal development and two physical development studies with a total of 2 899 children. Studies of cadmium exposure and menarche in girls all found that late menarche in children with higher urinary cadmium concentrations ( HR=0.86, 95%CI=0.74-0.99, P < 0.05 ; 3 studies; moderate certainty evidence), and one of these studies found no statistically significant effect of cadmium exposure on breast and pubic hair development in children ( aOR=0.90, 95%CI =0.72-1.14; aOR=0.85, 95%CI=0.64-1.13, P >0.05; low quality evidence); the only study testicular volume, external genitalia and pubic hair development in boys found on effects of urinary cadmium exposure on pubertal development ( aOR=0.76, 95%CI =0.50-1.15; aOR=1.07, 95%CI =0.79-1.45; aOR= 0.79 , 95%CI=0.51-1.23, P >0.05; low certainty evidence). Regarding the effects of cadmium exposure on children s height and weight (2 studies, low certainty evidence), the results of one study showed that cadmium exposure was negatively associated with children s physical growth (multivariable adjusted attributable differences in height and weight study, being -1.60 cm, 95% CI = -2.40 to -0.77 cm; and -0.57 kg, 95% CI =-0.88 to -0.26 kg, P <0.05), while the other showed no effect of cadmium exposure on children s height and weight ( F= 1.35 ,1.76, P >0.05), but a negative effect on head and chest circumference ( F=3.43, 4.50, P <0.05; low certainty evidence). Conclusion Cadmium exposure in childhood causes delayed menarche in girls and affects physical growth to some extent.

Objective To analyze the abnormal individual dose monitoring results in 206 medical institutions in a selected region in 2024, and to propose improvement measures. Methods Individuals with monitoring results exceeding the investigation level were subjected to high-dose investigation, and the results were statistically analyzed. Results In 2024, the individual dose monitoring of 206 medical institutions in a selected region showed 1.04% abnormal results. The proportions of abnormal results from primary, secondary, and tertiary medical institutions were 12.22%, 3.33%, and 84.45%, respectively. In analysis of the causes of abnormal results, 52.53% of the cases were due to personal dosimeters left in the radiation workplace, and 20.20% were due to the confusion in wearing personal dosimeters inside and outside the lead apron. In analysis of the occupational distribution of the radiation workers with abnormal monitoring results, interventional radiology and diagnostic radiology accounted for 73.34% and 24.44%, respectively. Statistical analysis of the dose range showed that doses in the ranges of 1.25-2.0 mSv and 2.0-5.0 mSv accounted for 42.22% and 33.33%, respectively. In the report of abnormal monitoring results, the proportions of reporting notional dose and reporting measured results accounted for 88.89% and 11.11%, respectively. Among institutions with consecutive abnormal results, primary, secondary, and tertiary medical institutions accounted for 15.39%, 7.69%, and 76.92%, respectively. Conclusion The level of the hospital, occupational type, the perceived importance of the hospital to the management of radiation protection, and the perceived importance and compliance of the radiation workers with the individual dose monitoring are potential causes of abnormal results. It is recommended that employers should enhance radiation protection training for their radiation workers to ensure proper wearing and storage of dosimeters, and progressively improve the standardization and effectiveness of individual dose monitoring practice.

Objective To compare H_p(3) calibration with a homemade (A) thermoluminescent dosimeter (TLD) and an imported (B) TLD in a standard X-ray RQR radiation field, to explore the different responses of A and B, and to provide foundation for the calibration of H_p(3). Methods A column mode was selected. H_p(3) calibration was performed using A and B in a standard X-ray RQR radiation field in the Secondary Standard Dosimetry Laboratory, National Institute for Radiological Protection, China Center for Disease Control and Prevention. Angle response, energy response, and linear response were calibrated with RQR4 (60 kV), RQR7 (90 kV), and RQR9 (120 kV), respectively. Results In terms of angle response, the calibration results of A were relatively high, while the calibration results of B were relatively low. In terms of energy response, the calibration results showed a similar pattern to angle response. In terms of linear response, the calibration results of both A and B were satisfactory. Conclusion Both A and B can be used for normal calibration of H_p(3) in a standard X-ray RQR radiation field. However, in actual monitoring, attention should be paid to the energy and angle response values of TLDs.

Objective:To summarize the clinical manifestations, neuroelectrophysiological characteristics and prognoses of Movan syndrome (MoS), and provide references for early diagnoses and prognoses.Methods:A retrospective analysis was performed. The clinical data, such as clinical symptoms, treatments and prognoses, laboratory test results and electrophysiological test results, of 13 patients with confirmed MoS in Department of Neurology, He'nan Provincial People's Hospital from January 2018 to October 2023 were collected.Results:Ten male MoS patients and 3 female ones were included. Main clinical manifestations of 13 patients with MoS included myokymia, pain, numbness of limbs, itching all over the body, hyperhidrosis, urinary and defecation disorder, tachycardia, insomnia, anxiety and depression. Ten patients completed the autoimmune encephalitis antibody detection: 3 only had positive anti-contactin-associated protein-like 2 (CASPR2) antibody, 2 only had positive anti-leucine-rich glioma-inactivated protein1 (LGI1) antibody, and 2 had both positive anti-CASPR2 antibody and anti-LGI1 antibody. Eleven patients completed tumor screening and 4 tumors (thymoma [ n=2], lung squamous cell carcinoma [ n=1] and adrenal non-Hodgkin's lymphoma [ n=1]) were noted. Ten patients completed electrocardiogram, including 3 patients with resting tachycardia and 2 patients with ST segment elevation. All patients completed the electromyographic examination; 12 patients showed abnormal motor unit potential, including myokymia potential, fasciculation potential and neuromyotonic potential; F-wave and/or M-wave post-discharge potentials were found in all patients. Follow up was performed for 1-12 months; in 9 non-tumor patients, 5 were improved in 6 patients accepted immunotherapy and one was improved in 3 patients received symptomatic treatment; in 4 tumor patients, only one was improved in 3 received immunotherapy. Conclusion:Myokymia, pain, urinary and defecation disorder, and severe insomnia are typical symptoms for MoS patients; serum anti-CASPR2/LGI1 antibody and electromyography results provide evidences for MoS diagnosis; early immunotherapy can improve the MoS prognosis, and MoS patients combined with tumors have poor clinical prognosis.

Objective:To explore the clinical characteristics of neurological syndrome associated with anti-glutamic acid decarboxylase (GAD) antibodies (Abs).Methods:Six patients with neurological syndrome associated with anti-GAD-Abs admitted to Department of Neurology, Henan Provincial People's Hospital from January 2019 to October 2022 were chosen. The clinical manifestations, imaging and laboratory results, therapeutic schedules, and follow-up prognoses of these patients were collected and summarized.Results:Three females and 3 males were included, with onset age of (54.3±17.7) years. Three patients had stiff-person syndrome (SPS), 1 had limbic encephalitis+generalized epilepsy, 1 had extralimbic encephalitis+occipital epilepsy, and 1 had cerebellar ataxia who was diagnosed with paraneoplastic syndrome associated with small cell lung cancer. Four patients had elevated level of thyroid peroxidase antibodies, and 1 patient was positive for overlapping anti-gamma aminobutyric acid B receptor antibodies and Amphiphysin antibodies. Two patients with SPS had failed lumbar puncture; 1 had slightly increased white blood cells and proteins in cerebrospinal fluid (CSF); the remaining 3 patients were basically normal. Specific oligoclonal bands in CSF were observed in 2 patients. Brain MRI showed abnormal signals in the bilateral occipital lobes in 1 patient, and no specific inflammatory lesions in other patients. All patients accepted corticosteroids and intravenous immunoglobulin/plasma exchange therapies; except for the one with paraneoplastic syndrome associated with small cell lung cancer, the remaining 5 patients had improved modified Rankin scale (mRs) scores at discharge and received long-term immunotherapy. Two patients with SPS had gradually aggravated symptoms, and mRs scores reached 5 at the last follow-up (one for 3 years and the other one for 2 years).Conclusions:The clinical manifestations of patients with neurological syndrome associated with anti-GAD-Abs include SPS, limbic encephalitis, extralimbic encephalitis, epilepsy and cerebellar ataxia; some of these patients have paraneoplastic syndromes. Immunotherapies are effective except for these patients with paraneoplastic syndromes. Some patients with SPS tend to have a chronic course and a poor prognosis.

OBJECTIVE: To screen the key genes related to the prognosis of lung adenocarcinoma through big data analysis and explore their clinical value and potential mechanism. METHODS: We analyzed GSE18842, GSE27262, and GSE33532 gene expression profile data obtained from the Gene Expression Omnibus (GEO). Bioinformatics methods were used to screen the differentially expressed genes in lung adenocarcinoma tissues and KEGG and GO enrichment analysis was performed, followed by PPI interaction network analysis, module analysis, differential expression analysis, and prognosis analysis. The expressions of MAD2L1 and TTK by immunohistochemistry were verified in 35 non-small cell lung cancer specimens and paired adjacent tissues. RESULTS: We identified a total of 256 genes that showed significant differential expressions in lung adenocarcinoma, including 66 up-regulated and 190 down-regulated genes. Thirty-two up-regulated core genes were screened by functional analysis, and among them 29 were shown to significantly correlate with a poor prognosis of patients with lung adenocarcinoma. All the 29 genes were highly expressed in lung adenocarcinoma tissues compared with normal lung tissues and were mainly enriched in cell cycle pathways. Seven of these key genes were closely related to the spindle assembly checkpoint (SAC) complex and responsible for regulating cell behavior in G2/M phase. We selected SAC-related proteins TTK and MAD2L1 to test their expressions in clinical tumor samples, and detected their overexpression in lung adenocarcinoma tissues as compared with the adjacent tissues. CONCLUSIONS Seven SAC complex-related genes, including TTK and MAD2L1, are overexpressed in lung adenocarcinoma tissues with close correlation with the prognosis of the patients.
