Objective:To explore the clinical feature and genetic variation of NPHS1 variant-associated nephropathy ( NPHS1-VAN) in Chinese patients. Methods:This study was a case-series analysis. Patients with NPHS1-VAN, who were treated and/or followed in the Department of Pediatrics, Nanfang Hospital, Southern Medical University between 2018 and 2023 were recruited into this study. Genotype, phenotype and their relationship were analyzed. Results:Nine NPHS1-VAN patients from 8 non-consanguineous Chinese families were collected, including 5 males and 4 females. There were 7 cases with an onset age within 3 months and 2 cases with an onset age of 6 months and 13 years, respectively. Seven patients harbored compound heterozygous variants, two had homozygous variants, including 8 missense variations,3 frameshift variants, and 1 splicing site variant. Four patients in 3 families harbored missense variant c.928G>A, two of them experienced spontaneous remission of proteinuria at the age of 1 year and 2 years, respectively, another one had persistent proteinuria and entered end stage renal disease (ESRD) at 11 years old. The other one had an onset age of 6 months with no response to steroids initially. She got complete remission by tacrolimus administered, but relapse frequently and partially responded to steroids later. Two patients of this group died, one of them died of respiratory failure 3 days after birth. Excessive amniotic fluid and fetal edema were acknowledged at 28 weeks of gestational age. He harbored compound heterozygous variants of NPHS1, c.1135C>G (R379G) and c.1339G>A (E447K). His mother previously experienced fetal death at 28 weeks gestational age for her first pregnant and stillborn at 36 weeks of gestational age for her second pregnant, respectively. One patient in this study who harbored homozygous variant of c.1339G>A (E447K) presented with a mild phenotype, onset age was 13 years old and didn't progress to ESRD yet at 21 years. Thus, variant E447K was hypothesized to be weakly pathogenic, while R379G may be strongly pathogenic with a risk of death. Five novel variants were identified in this group of patients, 3 missense variants (c.1135C>G, c.1157A>T, c.3197T>A) and 2 frameshift variants (c.709_710delCT, c.3193delG). Renal biopsy was performed in 4 cases, of whom two were focal segmental glomerular sclerosis and another two were minimal change disease. Conclusions:NPHS1-VAN possesses remarkable clinical and genetic heterogeneity. Five novel variants were identified. Missense variant is the most common variant type and c.928G>A is the most common one in this group of patients, in consistent with previous report in China. Children harbor c.928G>A may have a mild phenotype with possible spontaneous remission and may be response to steroids and calcineurin inhibitor. Variant c.1135C>G (R379G) may have a strong pathogenicity, and patient who harbors this variant may have a severe phenotype.

Objective:To explore the relationship between urinary cadmium levels and thyroid hormone levels in people aged 40-89 years old in selected areas of China.Methods:Based on the "Investigation of the Impact of Soil Quality of Agricultural Land on Human Health in Typical Areas" project from October 2019 to August 2020, a multi-stage stratified random sampling method was used to include 6 588 middle-aged and older adults aged 40-89. Demographic characteristics, dietary frequency and disease status were collected through the questionnaire and physical examination. Urinary cadmium and urinary creatinine were detected by random midstream urine. Fasting venous blood was collected for the detection of Triiodothyronine (T3) and Thyroxine (T4). The linear mixed effects model was used to explore the association of urine cadmium levels with thyroid hormone levels. Its dose-response relationship was explored by using the restricted cubic spline.Results:The age of the subjects was (63.48±12.18) years, with males accounting for 51.28%. The M ( Q 1,Q 3) of urinary cadmium level, T3 and T4 was 2.48 (1.36, 4.42) μg/g·creatinine, (1.96±0.51) nmol/L and (113.75±29.11) nmol/L, respectively. The linear mixed effects model showed that the changes of T3 and T4 were 0.027 (0.009, 0.044) nmol/L and 2.019 (1.084, 2.953) nmol/L for each one-unit increase (natural logarithm transformed) of urinary cadmium. The restricted cubic spline showed that there was a positive nonlinear association between urinary cadmium and T3 as well as T4 (all Pnonlinear<0.05). Conclusion:In selected areas of China, the urinary cadmium level of middle-aged and older adults aged 40-89 years is positively associated with T3 and T4.

Objective:To investigate the effect of low-dose aspirin combined with dydrogesterone in the treatment of patients with polycystic ovary syndrome (PCOS) complicated with infertility and its influence on hormones and helper T cytokines.Methods:300 PCOS patients with infertility in the Second Affiliated Hospital of Air Force Military Medical University were selected from January 2018 to October 2023. A prospective randomized controlled study was performed. The study subjects were divided into control group and observation group by random envelope method, with 150 cases in each group. The control group was treated with dydrogesterone on the basis of routine intervention, while the observation group was combined with low-dose aspirin on the basis of the control group. The efficacy, pregnancy rate, hormones, Th1 and Th2 cytokines and incidence of adverse reactions were compared in between groups. Measurement data with normal distribution was represented by xˉ± s. Comparison between groups was performed by two-sample t-test and paired t-test was used for comparison before and after treatment. Enumeration data was represented by n(%). Comparison between groups was performed by χ2 test. Results:After treatment, the total effective rate of treatment and pregnancy rate in observation group were higher than those in control group [86.00%(129/150) vs. 74.67% (112/150), 63.33% (95/150) vs. 47.33% (71/150)] ( χ2=6.10, P=0.014, χ2=6.73, P=0.010). Serum levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) in both groups were lower after treatment than those before treatment, and the levels in observation group were lower than those in control group [(5.27±1.01) U/L vs. (6.40±1.13) U/L, (6.78±0.87) U/L vs. (7.16±0.91) U/L], and serum estradiol level was higher than that before treatment, and the level in observation group was higher compared to control group [(93.35±8.17) ng/L vs. (82.45±9.14) ng/L] ( t=9.13, 3.70, 10.89, all P<0.001). After treatment, serum γ-interferon, interleukin (IL-2), IL-4 and IL-6 levels were all lower in both groups than those before treatment, and the above levels were lower in observation group than those in control group [(56.96±4.64) ng/L vs. (61.36±4.41) ng/L, (38.74±7.43) ng/L vs.(45.63±8.64) ng/L, (41.03±7.06) ng/L vs. (43.36±8.12 ng/L), (23.14±4.33) ng/L vs. (27.14±5.14) ng/L] ( t=8.42, 7.40, 2.65, 7.29, P<0.001, <0.0 010.008, <0.001). There was no statistical significance in the total incidence rate of adverse reactions between observation group and control group [12.67%(22/150) vs. 9.33% (14/150), χ2=0.85, P=0.356]. Conclusions:Low-dose aspirin combined with dydrogesterone has a significant clinical effect in the treatment of PCOS with infertility, and it can improve 3-month pregnancy rate, and effectively regulate hormones levels and Th1 and Th2 cytokines, and it will not increase adverse reactions, with high safety.

BACKGROUND:The asymmetrical biomechanical environment of adolescent idiopathic scoliosis can lead to further wedge deformation of the vertebral body,which may affect cardiopulmonary function and compress nerves in severe cases.Adolescent idiopathic scoliosis with different degrees of scoliosis should be treated with exercise,bracing,and surgery.However,the mechanical mechanism of selecting an orthopedic approach remains unclear due to the individual variability of patients.OBJECTIVE:To investigate the biomechanical mechanism of different orthopedic modalities for the treatment of adolescent idiopathic scoliosis to provide a basis for clinical selection of treatment modalities based on the spine model of adolescent idiopathic scoliosis patients.METHODS:Based on the CT images of an adolescent idiopathic scoliosis patient,a scoliosis model(C7-L5)was reconstructed in Mimics software in three dimensions,and lateral thrust force was applied at the T8/T9 thorax and vertical distraction force was applied over the C7 vertebra with the magnitude of 20,40,60,80,100,and 120 N.The intervertebral disc stress and vertebral displacement in concave and convex sides,and Cobb angle of the spine were analyzed under two orthopedic modalities.RESULTS AND CONCLUSION:(1)With lateral thrust,there was no significant change in the C7T1-T7T8 intervertebral disc.The concave and convex stress of T7T8-L4L5 segment decreased first and then increased with the increase of lateral thrust force.The correction effect of lateral thrust on the segment near T8T9 was obvious and weakened with the extension of the segment to the cephalic and caudal ends.At 120 N of lateral thrust,the thoracic Cobb angle changed from 53.2° to 32.5° and the lumbar Cobb angle changed from 50.2° to 43.9°.(2)With the vertical distraction,the thoracic intervertebral disc stresses first decreased and then increased,and all the lumbar disc stresses decreased.The C7 displacement was the most obvious,and the correction effect gradually diminished with the segment extended to the caudal end.At a vertical distraction force of 120 N,the thoracic Cobb angle changed from 53.2° to 39.4° and the lumbar Cobb angle changed from 50.2° to 47.6°.(3)It is concluded that both orthopedic modalities provide improvement in the degree of scoliosis,with the thoracic correction being greater than the lumbar correction.Also,the asymmetric stress distribution on the concave and convex sides is improved,which contributes to normal bone growth.A vertical distraction approach is appropriate for larger Cobb angles,and a lateral thrust approach is appropriate for smaller Cobb angles.The results of this study help to understand the mechanism of spinal orthosis and provide a theoretical basis for the choice of orthopedic approach.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

Heatstroke, a life-threatening illness, poses a significant risk to human health, particularly in high-temperature and high-humidity environments. Timely and effective on-site management is critical for improving patient survival and prognosis. Rapid recognition, rapid assessment, and rapid cooling are the cornerstones of pre-hospital care. However, the absence of a standardized protocol for pre-hospital management of heatstroke has impeded the efficacy of treatment. This consensus, initiated by the Expert Group on Heatstroke Prevention of the People's Liberation Army, signifies a collaborative endeavor involving emergency medical personnel, nurses, and administrators from pre-hospital care, emergency departments, and intensive care units in both military and civilian domains. By systematically reviewing evidence-based medicine and clinical expertise in heatstroke prevention, on-site and in-transit care, as well as early treatment in emergency settings, the group has formulated the Expert consensus on pre-hospital emergency management of heatstroke (2024) after extensive discussions and iterative recommendations, which serve as a scientific and standardized framework for pre-hospital heatstroke emergency care. The consensus underscores the pivotal role of enhancing public awareness regarding heatstroke prevention and augmenting the rates of rapid recognition and rapid cooling for effective on-site heatstroke management. In high-risk industries, regions, or seasons for heatstroke, developing scientifically sound plans and conducting practical training can provide effective safety measures. Emergency personnel should undergo specialized training and assessments in knowledge and skills, ambulances should be equipped with effective cooling devices, and hospitals must maintain comprehensive emergency response capabilities. It is recommended to establish a regional heatstroke treatment network to optimize the allocation of emergency resources and streamline processes, thereby improving treatment outcomes and response times.

Objective:To develop a post competence assessment scale for nurses in the health management (physical examination) center and assess its reliability and validity.Methods:This study adopted an empirical approach. A total of 801 nurses from the health management (physical examination) center were recruited to participate in this study. A research team was formed in August 2024. This team transformed the previously constructed core competence evaluation index system for health management specialist nurses in the health management (physical examination) center (comprising 6 first-level indicators and 70 third-level indicators) into a preliminary post competence assessment scale. Seven experts evaluated the content validity of the scale. In September 2024, a pilot survey was conducted among 27 nurses from the health management (physical examination) center of Sichuan Provincial People′s Hospital using convenience sampling. From October to November 2024, the first main survey was administered to 385 nurses of health management (physical examination) center across 54 cities in China using both convenience sampling and snowball sampling methods, followed by exploratory factor analysis (EFA). Subsequently, utilizing the refined scale obtained after eliminating certain items, a second main survey was conducted among 389 nurses in the health management (physical examination) center, followed by a confirmatory factor analysis (CFA). The reliability of the final scale was assessed using Cronbach′s α coefficient, split-half reliability, composite reliability, and test-retest reliability.Results:The finalized scale for nurses′ post competency in health management (physical examination) center comprises five dimensions—basic nursing service competency, health management practice competency, knowledge integration competency, professional development competency, and professional attitude—with a total of 57 items. The item level content validity index (I-CVI) of the items of the content validity display scale ranged from 0.857 to 1.000, and the content validity index of each dimension ranged from 0.984 to 1.000. The scale-level Content Validity index/average (S-CVI/Ave) was 0.995. The contribution rate of the 6 factors extracted by EFA was 74.07%. After group discussion and CFA, the scale of the 5-factor structural equation model was constructed. The total Cronbach′s α coefficient of the scale was 0.986, the split-half reliability was 0.865, the composite reliability was 0.960-0.980, the total table test-retest reliability was 0.762, and the test-retest reliability of each dimension was 0.681-0.731.Conclusion:The developed assessment scale for assessing the post competence of nurses in the health management (physical examination) center demonstrates excellent reliability and validity.

Objective:To analyze the detection status and its influencing factors of ovarian-adnexal masses in the physical examination population based on the Ovarian-Adnexal Imaging Reporting and Data System (O-RADS) of the American College of Radiology.Methods:This cross-sectional study retrospectively analyzed the clinical data of 24 316 physical examination participants who underwent gynecological color Doppler ultrasound examinations at the Health Management Center of Tianjin Medical University General Hospital from January to December 2021. The subjects were classified and followed-up according to O-RADS, and the detection rate and malignancy rate of ovarian-adnexal masses in different classifications were compared. According to O-RADS classification criteria, the physical examination population were divided into healthy control group (without ovarian-adnexal masses and O-RADS 1 class, 23 188 cases), benign group (O-RADS 2 class, 946 cases) and malignant group (O-RADS 3-5 class, 182 cases). The basic information of the three groups were compared, including age, body mass index (BMI), menopausal status, marital status, smoking history, drinking history, physical exercise, complete blood count, blood glucose, blood lipids, tumor markers, etc. The logistic regression was used to analyze the factors affecting the detection of ovarian-adnexal masses.Results:A total of 24 316 individuals were included, 1 678 with ovario-adnexal masses were screened, among the cases, there were 550 normal premenopausal ovaries (32.78%), and 1 128 cases were confirmed with pathological masses (67.22%). Of the 318 cases with follow-up records, the malignancy rate for O-RADS 4 class was 50%, and for O-RADS 5 class, it was 100%, according to the follow-up results. The age ( OR=1.320, 95% CI: 1.055-1.653), BMI ( OR=0.972, 95% CI: 0.954-0.989), carbohydrate antigen 125(CA125) ( OR=1.090, 95% CI: 1.023-1.161), postmenopausal ( OR=0.919, 95% CI: 0.892-0.947) and married and cohabiting ( OR=0.921, 95% CI: 0.895-0.949) were positively correlated with risk of ovarian-adnexal masses (all P0.05). Conclusions:The O-RADS classification system has high application value in evaluating the malignant risk of ovarian-adnexal masses; the age, BMI, CA125 levels, menopausal status, and marital status are significant influencing factors for the detection of ovarian-adnexal masses.
