Using Liquid Chromatography-Tandem Mass Spectrometry in Detecting Plasma Lyso-GL3 Levels in Patients with Fabry Disease and the Association Analysis of Phenotype-Genotype of the Disease / 罕见病研究

ObjectiveUsing the liquid chromatography-tandem mass spectrometry (LC-MS/MS) to determine the plasma level of Lyso-GL3 in patients with Fabry disease and to analyze the clinical application of the method.MethodsThirty-nine patients with a genetic diagnosis of Fabry disease were included, and plasma levels of Lyso-GL3 were measured by LC-MS/MS analysis, and detailed clinical information of the patients was obtained including: α-galactosidase A activity, genetic variants, quantification of urine protein, mean arterial pressure, and estimation of glomerular filtration rate, and the differences in the levels of Lyso-GL3 in different clinical phenotypes and genotypes were statistically analyzed, as well as the association with clinical indicators.ResultsLyso-GL3 showed good linearity within 0.7856-400 ng/mL(r=0.9992).Further analysis of 39 Fabry disease patients diagnosed in Ruijin Hospital, Shanghai Jiao Tong University School of Medicine showed a median Lyso-GL3 concentration of 23.6 ng/mL(4.3-92.9 ng/mL); Lyso-GL3 levels were significantly higher in patients with both the frameshift and the splicing mutations, as well as in patients with the nonsense mutations, than in patients with the missense mutations (median value 119.7 ng/mL vs. 11.9 ng/mL, P=0.006, and median value 97.0 ng/mL vs. 11.9 ng/mL, P=0.015, respectively). Whereas, association analysis revealed that Lyso-GL3 was not significantly associated with urinary protein, mean arterial pressure and estimated glomerular filtration rate.ConclusionsThe using of LC-MS/MS to quantify plasma Lyso-GL showed significant differences in Lyso-GL3 concentrations between classical and atypical phenotypes, suggesting that plasma Lyso-GL3 may help with clinical phenotypes. However, Lyso-GL3 levels is found to be overlapped between genotypes. No significant linear correlation was found between Lyso-GL3 and renal clinical indicators, suggesting the urgent need in finding a more accurate tool to assess renal involvement and prognosis in patients with Fabry disease.

Considerations on the improvement of height benefit in children with central precocious puberty / 中国当代儿科杂志

With the changes in various factors such as genetics and the environment, the incidence of childhood precocious puberty has been gradually increasing. Improving height is one of the key issues in the clinical management of precocious puberty. Currently, gonadotropin-releasing hormone analogs (GnRHa) remain the preferred treatment for precocious puberty, but their effect on height improvement is influenced by multiple factors, which may result in lower-than-expected height benefits. Combining recombinant human growth hormone (rhGH) therapy with GnRHa treatment is an alternative strategy to enhance the efficacy of GnRHa, but there is still no clear recommendation regarding the timing of their combination. Considering the current status of precocious puberty treatment, it is crucial to reevaluate the effects of GnRHa monotherapy and combination therapy with rhGH on height improvement. This article discusses strategies such as combination therapy indications to guide clinical medication and help children with precocious puberty achieve optimal height benefits.

No Incidence of Liver Cancer Was Observed in A Retrospective Study of Patients with Aristolochic Acid Nephropathy / 中国结合医学杂志

OBJECTIVE@#To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN).@*METHODS@#A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014.@*RESULTS@#A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer.@*CONCLUSIONS@#No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

Alterations in dendritic length and branch and K / 解剖学报

Objective To study the morphology of olfactory bulb(OB) neurons and the change of related proteins, and explore the causes of olfactory dysfuction in Alzheimer' s disease(AD). Methods Golgi-Cox staining technique was used to evaluate the morphological changes of neurons in the OB and anterior piriform cortex (aPC) of APP/PS1 AD model mice. The morphology of neurons was determined by Sholl analysis. Western blotting was used to evaluate the levels of protein expression. Results The results of Golgi-Cox showed that the dendrite length and branch number reduced significantly in the OB neurons of 3-5-month-old APP/PS1 mice, an age that the mice did not show the pathological characteristics and cognitive impairment of AD. Western blotting analysis showed that levels of potassium chloride cotransporter 2(KCC2), a potassium chloride transporter crucial for neuronal morphology and synaptic function, decreased significantly in the OB of 3-5-month-old APP/PS1 mice. Conclusion Abnormal neuronal morphology and KCC2 signal might be the basis of early olfactory dysfunction in AD. Thus, maintaining normal KCC2 signal may be one of the keys to intervene the olfactory abnormalities in the early stage of AD.

Role of FoxO1/p38MAPK signaling pathway in acute lung injury induced by LPS / 中国药理学通报

Aim To investigate the effect of forkhead transcription factors of O classl (FoxO1) on lipopolysaccharide (LPS) -induced acute lung injury and its regulatory mechanism. Methods The model of acute lung injury (ALI) was simulated by LPS. HE staining was used to observe the pathological changes of lung tissues. The contents of tumor necrosis factor a (TNF-a) and interleukin-6 (IL-6) in lung tissues were determined by ELISA. The expression of FoxOl in mouse lung tissues was observed by immunohistochemical staining. The phosphorylation levels of FoxOl, DNA methyltransferase and p38 MAPK were detected by Western blot. The mRNA levels of FoxOl, IL-6, TNF-a and DNA methyltransferase were detected by qRT-PCR. DNA methylation in FoxOl promoter region in lung tissues was detected by nested methylation specific PCR (nMS-PCR). Pulmonary vascular endothelial cells (PVECs) were cultured and transfected with FoxOl siRNA, and the phosphorylation of p38 MAPK was detected by Western blot. The correlation between FoxOl methylation level and inflammatory factors was analyzed by Pearson method. Results Compared with control group, alveolar inflammatory cells increased significantly in LPS group, and pulmonary edema and hyperemia were obvious. TNF-α and IL-6 levels increased by 52. 2% and 150. 4% (P < 0. 05), respectively. The phosphorylation level of p38 MAPK and FoxOl expression increased by 134. 1% and 61. 8% (P < 0. 05), respectively, while the DNA methylation level of Fox0l promoter region decreased by 17. 2% (P < 0. 05). After transfection of FoxOl siRNA in vitro, the phosphorylation level of p38 decreased. Pearson analysis showed that FoxOl methylation level was negatively correlated with inflammatory factors. Conclusion The regulation of FoxOl/p3 8 MAPK signaling pathway by hypomethylation of FoxOl promoter is an important mechanism of LPS-induced acute lung injury.

Effects of preoperative diagnostic hysteroscopy on peritoneal cytology and prognosis in patients with non-endometrioid carcinoma / 中华妇产科杂志

Objective: To explore the effects of preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage on the risk of abdominal dissemination and prognosis of non-endometrioid carcinoma. Methods: The clinical and pathological data of 97 patients who underwent surgical treatment and were pathologically confirmed as non-endometrioid carcinoma (including serous carcinoma, clear cell carcinoma, mixed adenocarcinoma, and undifferentiated carcinoma, etc.) from October 2008 to December 2021 in Peking University People's Hospital, were collected for retrospective analysis. According to preoperative diagnostic methods, they were divided into hysteroscopic group (n=44) and non-hysteroscopic group (n=53). The impact of hysteroscopy examination on peritoneal cytology and prognosis was analyzed. Results: (1) There were no statistical differences in age, body mass index, tumor size, pathological characteristics, and treatment methods between the hysteroscopic group and the non-hysteroscopic group (all P>0.05), but the proportion of stage Ⅰ-Ⅱ patients in the hysteroscopic group was significantly higher than that in the non-hysteroscopic group [68% (30/44) vs 47% (25/53); χ2=4.32, P=0.038]. (2) Among 97 patients, 25 (26%, 25/97) of them were cytologically positive for ascites. The hysteroscopic group had a lower positive rate of peritoneal cytology than that in the non-hysteroscopy group, which was significantly different [11% (5/44) vs 38% (20/53); χ2=8.74, P=0.003]. Stratification according to surgical and pathological stages showed that the positive rate of peritoneal cytology in the hysteroscopic group (3%, 1/30) was lower than that in the non-hysteroscopic group (12%, 3/25) in the 55 patients with stage Ⅰ-Ⅱ, and that in the hysteroscopic group (4/14) was also lower than that in the non-hysteroscopic group (61%, 17/28) in the 42 patients with stage Ⅲ-Ⅳ. There were no significant differences (all P>0.05). (3) The 5-year disease-free survival (DFS) rate of the hysteroscopic group and the non-hysteroscopic group were respectively 72.7% and 60.4%, and there was no significant difference between the two groups (P=0.186). After stratification according to staging, the 5-year DFS rate were respectively 90.0% and 72.0% (P=0.051) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅰ-Ⅱ, and 35.7% and 50.0% (P=0.218) between the hysteroscopic and non-hysteroscopic groups of patients in stage Ⅲ-Ⅳ, in which there were not statistically significant differences. The 5-year overall survival (OS) rate were respectively 86.4% and 81.1% between the hysteroscopic group and the non-hysteroscopic group, with no significant difference between the two groups (P=0.388). The 5-year OS rate were respectively 93.3% and 96.0% in the hysteroscopic group and non-hysteroscopic group for patients with stage Ⅰ-Ⅱ(P=0.872), and 71.4% and 67.9% in the hysteroscopic group and non-hysteroscopic group in patients with stage Ⅲ-Ⅳ (P=0.999), with no statistical significance. Conclusions: Diagnostic hysteroscopy do not increase the rate of positive peritoneal cytology result at the time of surgery in this cohort, and no significant correlation between preoperative hysteroscopy examination and poor prognosis of non-endometrioid carcinoma is observed. Therefore, preoperative hysteroscopic guided biopsy and segmental diagnosis and curettage in non-endometrioid carcinoma maybe safe.

AIM: To evaluate the applicability of Chinese dry eye questionnaire in college students using the ocular surface disease index(OSDI)questionnaire as a reference.METHODS: Cross-sectional study. A total of 711 college students from Nanyang Medical College were enrolled in the study and assessed for dry eye condition using OSDI questionnaire and Chinese dry eye questionnaire. The response rate of each question in the two questionnaires was counted. Cronbach α was calculated to evaluate the internal consistency of both questionnaires. Correlation between the total scores of the two questionnaires was analyzed to evaluate the criterion validity. Based on OSDI scores, the discriminant validity of Chinese dry eye questionnaire was evaluated; receiver operating characteristic(ROC)curves was plotted for Chinese dry eye questionnaire scores, area under the ROC curve(AUC)was calculated, and diagnostic thresholds and corresponding sensitivity and specificity were also analyzed.RESULT: The response rates of the 12 questions on the OSDI questionnaire were 33.2%-100.0%, while it was 100.0% for each question on the Chinese dry eye questionnaire. The Cronbach α values of OSDI questionnaire and Chinese dry eye questionnaire were 0.905 and 0.789, respectively. The Chinese dry eye questionnaire score was positively correlated with the OSDI score(rs=0.712, P&#x003C;0.001). According to OSDI questionnaire scores, dry eye severity was divided into normal group, mild dry eye group, moderate dry eye group and severe dry eye group. The scores of Chinese dry eye questionnaire in these groups were 4.00(2.00, 6.00), 9.00(7.00, 11.00), 12.00(9.00, 14.00)and 16.00(13.50, 22.00), respectively, which increased with the severity of dry eye, and the overall difference was statistically significant(P&#x003C;0.001), as well as pairwise comparison between groups(P&#x003C;0.05). The AUCs of Chinese dry eye questionnaire in distinguishing normal population from dry eye population, mild dry eye from moderate dry eye, moderate dry eye from severe dry eye were 0.862, 0.661 and 0.769, respectively, and the diagnostic thresholds were 6.5, 11.5 and 14.5, respectively.CONCLUSION:Chinese dry eye questionnaire has an equivalent reliability, validity, discriminant ability and better response rate for dry eye screening and epidemiological survey among college students in China compared with OSDI questionnaire.

ObjectiveTo investigate the effect and mechanism of Nongsuo Dangguiwan in improving ovarian oxidative stress in rats with ovarian dysfunction. MethodThirty-six adult female SD rats were randomly divided into normal group， model group， positive drug group （Femoston， 0.3 mg·kg-1）， and high-， medium-， and low-dose groups of concentrated Nongsuo Dangguiwan （2.08， 4.16， 8.32 g·kg-1）， with six rats in each group. Rats， except for those in the normal group， were injected with 80 mg·kg-1 vinyl cyclohexene dioxide （VCD） per day for 14 consecutive days to induce ovarian dysfunction. From the 15th day， rats were treated with corresponding drugs by gavage， while those in the model group received 2 mL·kg-1 saline， once daily for 28 consecutive days. The ovarian index， levels of related hormones including estradiol （E2）， follicle-stimulating hormone （FSH）， luteinizing hormone （LH）， and anti-mullerian hormone （AMH） in serum， as well as superoxide dismutase （SOD） activity and glutathione （GSH） content in serum were measured by enzyme-linked immunosorbent assay （ELISA）. The malondialdehyde （MDA） content in serum was detected by the thiobarbituric acid （TAB） method. Ovarian morphology was observed by hematoxylin-eosin （HE） staining. The expression of nuclear factor E2-related factor 2 （Nrf2）， heme oxygenase-1 （HO-1）， SOD2， and SOD1 in ovarian tissues was detected by immunohistochemistry （IHC） and Western blot. ResultCompared with the normal group， the model group showed a significant reduction in growing follicles in the ovary， loose arrangement of granulosa cells in the follicle， decreased body weight， ovarian index， and serum AMH and E2 levels， increased LH and FSH levels （P<0.01）， reduced levels of SOD and GSH in serum （P<0.01）， and increased MDA level （P<0.01）. Compared with the model group， the groups with drug intervention showed increased ovarian index （P<0.05， P<0.01）， increased serum E2 level （P<0.05， P<0.01）， decreased FSH， AMH， and LH levels （P<0.05， P<0.01）， increased number of growing follicles in the ovary， potentiated SOD activity in serum， increased GSH content， decreased MDA content （P<0.05， P<0.01）， and up-regulated expression levels of Nrf2， HO-1， SOD2， and SOD1 proteins in ovarian tissues （P<0.05， P<0.01）. ConclusionNongsuo Dangguiwan can regulate serum hormone levels， increase the expression of Nrf2， HO-1， SOD2， and SOD1 in ovarian tissues， and improve ovarian antioxidant capacity to resist oxidative stress injury， thereby improving ovarian reserve function.

Association between Fruit and Vegetable Intake and Arterial Stiffness: The China-PAR Project / 生物医学与环境科学（英文）

OBJECTIVE@#This study aimed to investigate the association between fruit and vegetable intake and arterial stiffness.@*METHODS@#We conducted a cohort-based study comprising 6,628 participants with arterial stiffness information in the Prediction for Atherosclerotic Cardiovascular Disease Risk in China (China-PAR) project. A semi-quantitative food-frequency questionnaire was used to assess baseline (2007-2008) and recent (2018-2021) fruit and vegetable intake. We assessed changes in fruit and vegetable intake from 2007-2008 to 2018-2021 in 6,481 participants. Arterial stiffness was measured using the arterial velocity-pulse index (AVI) and arterial pressure-volume index (API). Elevated AVI and API values were defined according to diverse age reference ranges.@*RESULTS@#Multivariable-adjusted linear regression models revealed that every 100 g/d increment in fruit and vegetable intake was associated with a 0.11 decrease in AVI ( B= -0.11; 95% confidence interval [ CI]: -0.20, -0.02) on average, rather than API ( B = 0.02; 95% CI: -0.09, 0.13). The risk of elevated AVI (odds ratio [ OR] = 0.82; 95% CI: 0.70, 0.97) is 18% lower in individuals with high intake (≥ 500 g/d) than in those with low intake (< 500 g/d). Furthermore, maintaining a high intake in the past median of 11.5 years of follow-up was associated with an even lower risk of elevated AVI compared with a low intake at both baseline and follow-up ( OR = 0.64; 95% CI: 0.49, 0.83).@*CONCLUSION@#Fruit and vegetable intake was negatively associated with arterial stiffness, emphasizing recommendations for adherence to fruit and vegetable intake for the prevention of arterial stiffness.

Evaluation of the lower urinary tract function using voiding spot assay in mice / 生理学报

The objective of present study was to develop a simple and reliable voiding spot assay (VSA) system to evaluate the lower urinary tract function of mice, and to establish it as a standardized protocol. Ultraviolet (UV) light was used to screen out the filter paper without autofluorescence and with optimal urine diffusion properties. Next, the appropriate wavelength of UV was determined based on the quality of the photographic image of urine spots on the filter paper. To confirm that the urine stain area on the filter paper was correlated with the amount of urine, a volume-area standard curve was constructed. The utility of this VSA system was validated using female wild-type C57BL/6J mice aged 12-13 weeks, and the data generated under identical procedural settings were compared among laboratories. Furthermore, this VSA system was employed to analyze the changes in voiding patterns in mice with urinary tract infections or transportation stress. No. 4 filter paper with a thickness of 0.7 mm was identified as the most suitable material for VSA, exhibiting no autofluorescence and facilitating optimal urine diffusion. The filter paper retained its integrity during the assay, and there was a linear correlation between urine volume and stained area under 365 nm UV light. Utilizing this VSA system, we determined that female wild-type C57BL/6J mice produced approximately 695.8 μL total urine and 5.5 primary voiding spots (PVS) with an average size of 126.4 μL/spot within 4-h period. Over 84% of PVS volumes ranged from 20 to 200 μL. Notably, PVS volumes of mice were similar across different laboratories. Mice with urinary tract infections or transportation stress exhibited significant changes in VSA parameters, including increased voiding frequency, PVS number, and decreased PVS volume. Therefore, this VSA system can be used to evaluate the urinary function of normal mice, as well as those with urinary tract infection or transportation stress.

Research advances on the role of ACSL3 in the atherosclerosis / 生理学报

Lipids droplets are organelles that store neutral lipids and are closely related to lipid accumulation. Long chain acyl-coenzyme A synthetase 3 (ACSL3) is a lipid droplet-associated protein mainly distributed in the cell membrane, endoplasmic reticulum, and intracellular lipid droplets, and its distribution depends on cell type and fatty acid supply. ACSL3 is a key regulator of fatty acid metabolism that is closely related to intracellular lipid accumulation, and plays an important role in various pathophysiological processes such as lipid droplet synthesis and lipid metabolism, cellular inflammation, and ferroptosis. This paper mainly reviews the role of ACSL3 in lipid synthesis, ferroptosis, and inflammatory response, with focus on the mechanism of its role in lipid accumulation in atherosclerosis, and provides new ideas for exploring potential therapeutic targets in atherosclerotic diseases.

Association of baseline serum cholesterol with benefits of intensive blood pressure control / 中华医学杂志(英文版)

BACKGROUND@#Intensive systolic blood pressure (SBP) control improved outcomes in the Strategy of Blood Pressure Intervention in the Elderly Hypertensive Patients (STEP) trial. Whether baseline serum lipid parameters influence the benefits of intensive SBP control is unclear.@*METHODS@#The STEP trial was a randomized controlled trial that compared the effects of intensive (SBP target of 110 to <130 mmHg) and standard (SBP target of 130 to <150 mmHg) SBP control in Chinese patients aged 60 to 80 years with hypertension. The primary outcome was a composite of cardiovascular disease events. A total of 8283 participants from the STEP study were included in this post hoc analysis to examine whether the effects of the SBP intervention differed by baseline low-density lipoprotein cholesterol (LDL-C) and non-high-density lipoprotein cholesterol (non-HDL-C) concentrations.@*RESULTS@#Regardless of the randomized SBP intervention, baseline LDL-C and non-HDL-C concentrations had a J-shaped association with the hazard of the primary outcome. However, the effects of the intensive SBP intervention on the primary outcome were not influenced by baseline LDL-C level ( P for interaction = 0.80) and non-HDL-C level ( P for interaction = 0.95). Adjusted subgroup analysis using tertiles in LDL-C1 (hazard ratio [HR], 0.77; 95% confidence interval [CI], 0.52-1.13; P = 0.18), LDL-C2 (HR, 0.81; 95% CI, 0.55-1.20; P = 0.29), and LDL-C3 (HR, 0.68; 95% CI, 0.47-0.98; P = 0.04) was provided, with an interaction P value of 0.49. Similar results were showed in non-HDL-C1 (HR, 0.87; 95% CI, 0.59-1.29; P = 0.49), non-HDL-C2 (HR, 0.70; 95% CI, 0.48-1.04; P = 0.08), and non-HDL-C3 (HR, 0.67; 95% CI, 0.47-0.95; P = 0.03), with an interaction P -value of 0.47.@*CONCLUSION@#High baseline serum LDL-C and non-HDL-C concentrations were associated with increased risk of primary cardiovascular disease outcome, but there was no evidence that the benefit of the intensive SBP control differed by baseline LDL-C and non-HDL-C concentrations.@*CLINICAL TRIAL REGISTRATION@#ClinicalTrials.gov, NCT03015311.

Construction of a clinical prediction model for the impact of acupuncture on pregnancy outcomes in poor ovarian response (POR) patients based on a patient registry research platform / 中国针灸

OBJECTIVES@#To construct a clinical prediction model for the impact of acupuncture on pregnancy outcomes in poor ovarian response (POR) patients, providing insights and methods for predicting pregnancy outcomes in POR patients undergoing acupuncture treatment.@*METHODS@#Clinical data of 268 POR patients (2 cases were eliminated) primarily treated with "thirteen needle acupuncture for Tiaojing Cuyun (regulating menstruation and promoting pregnancy)" was collected from the international patient registry platform of acupuncture moxibustion (IPRPAM) from September 19, 2017 to April 30, 2023, involving 24 clinical centers including Acupuncture-Moxibustion Hospital of China Academy of Chinese Medical Sciences. LASSO and univariate Cox regression were used to screen factors influencing pregnancy outcomes, and a multivariate Cox regression model was established based on the screening results. The best model was selected using the Akaike information criterion (AIC), and a nomogram for clinical pregnancy prediction was constructed. The prediction model was evaluated using receiver operating characteristic (ROC) curves and calibration curves, and internal validation was performed using the Bootstrap method.@*RESULTS@#(1) Age, level of anti-Müllerian hormone (AMH), and total treatment numbers of acupuncture were independent predictors of pregnancy outcomes in POR patients receiving acupuncture (P<0.05). (2) The AIC value of the best subset-Cox multivariate model (560.6) was the smallest, indicating it as the optimal model. (3) The areas under curve (AUCs) of the clinical prediction model after 6, 12, 24, and 36 months treatment were 0.627, 0.719, 0.770, and 0.766, respectively, and in the validation group, they were 0.620, 0.704, 0.759, and 0.765, indicating good discrimination and repeatability of the prediction model. (4) The calibration curve showed that the prediction curve of the clinical prediction model was close to the ideal model's prediction curve, indicating good calibration of the prediction model.@*CONCLUSIONS@#The clinical prediction model for the impact of acupuncture on pregnancy outcomes in POR patients based on the IPRPAM platform has good clinical application value and provides insights into predicting pregnancy outcomes in POR patients undergoing acupuncture treatment.

Analysis of heart rate variability during blood donation / 中国输血杂志

【Objective】 To observe the regulation of autonomic nerves in blood donors during blood donation by heart rate variability analysis and explore the possible mechanism of donation related vasovagal reaction. 【Methods】 Electrocardiogram (ECG) of 90 blood donors was monitored by Fontaine Ⅰlead during the whole process of blood donation, and the 5-min heart rate variation before, during and after blood donation was analyzed. 【Results】 During the whole process of blood donation, the sympathetic HRV index (LF nu) and the sympathetic and vagal balance ability index (LF/HF) increased, whereas the vagal nerve index (pNN50, RMSSD, HFnu) and heart rate variability index (SDNN, Total power) decreased. For baseline heart rate variability of different blood donors (first-time vs. repeated, male vs. female, 18-24 years old vs. ≥25 years old, <400 mL vs. 400 mL) before blood donation, the pNN50, RMSSD and Total power of 18-24 years old blood donors were higher, but other indicators showed no significant difference. There were differences in HRV indexes of different types of blood donors during blood donation compared with before blood donation. The decrease of pNN50 and HFnu and the increase of LF/HF were larger in experienced blood donors than in first-time blood donors. The decrease of RMSSD was larger in male blood donors than in female blood donors; the change of LF/HF was larger in blood donors aged≥25 years than in blood donors aged 18-24 years; other indicators had no significant difference. 【Conclusion】 Blood donation leads to reflex readjustment of the cardiac autonomic tone: the sympathetic nerve is excited while the vagal nerve is suppressed. The cardiac autonomic nerve function of first-time blood donors, female donors and low-age (18-24 years old) donors to blood donation stress is not fully regulated. Donation related vasovagal reaction may be related to the autonomic nerve regulation function of blood donors.

Effect of online and offline collaborative and integrated mode on voluntary blood donation: Internet + blood donation souvenir / 中国输血杂志

【Objective】 To explore the effect of online and offline collaborative and integrated mode (Internet + blood donation souvenirs), and develop diversified scientific ways of caring for voluntary blood donors in combination with the potential expectation of the target population, ao as to recruit and retain more blood donors. 【Methods】 A total of 4 000 blood donors from Yichang Central Blood Station from January 1 to June 30, 2022 were selected, and they could collect souvenirs from online and offline. The intelligent platform V9.5 of modern blood station management information system of Qiao Technology was used to classify the data of online and offline souvenir distribution, and digital intelligent comparison and analysis on age, occupation, education, type (first-time blood donors or repeat blood donors), region (main urban districts of Yichang and other counties and suburban districts) and gender were carried out. 【Results】 A total of 1 400 blood donors chose online souvenirs, who were mainly under 25 years old, students, female, college education or above, urban areas and regular donors; 2 600 chose offline souvenirs, who were mainly over 25 years old, male, junior college degree or below, occupations other than students (medical workers, educators, etc.), counties and suburban districts, and first-time blood donors. The collaborative and integrated mode of the two distribution methods were complementary and had a good incentive effect on blood donor recruitment. 【Conclusion】 The online and offline collaborative and integrated mode demonstrates a good effect and meets the needs of different population. Digital intelligence system is helpful to develop diversified and scientific ways of caring for voluntary blood donors, recruit and retain more blood donors, achieve high-quality development of blood collection and supply, therefore guarantee the increasing demand for clinical blood use.

Relationship between depression, anxiety, stress and food addiction in primary and secondary school students / 中国学校卫生

Objective@#To explore the relationship between depression, anxiety, stress and food addiction among primary and secondary school students in Yixing City, so as to provide reference and suggestions for maintaining healthy eating behavior and psychological health intervention and promotion among primary and secondary school students in Yixing City.@*Methods@#From December 2022 to February 2023, a stratified cluster random sampling method was used to select 4 180 primary and secondary school students from four primary and secondary schools in Yixing City, Jiangsu Province. A questionnaire survey was conducted using the Depression Anxiety Stress Scale-21 (DASS-21) and related behavior questionnaires. The data was analyzed using χ 2 test, Wilcoxon, Kruskal Wallis H rank sum test, and binary Logistic regression.@*Results@#The prevalence of food addiction among primary and secondary school students in Yixing City was 0.98% (41 students), and there was no statistically significant difference in the comparison of food addiction, depression, anxiety, and stress scores among students of different genders and age groups ( Z/H = -1.34- 5.74, P >0.05). There was a positive correlation between food addiction and binge eating behavior, depression, anxiety, and stress symptoms ( r=0.14-0.23, P <0.01). The results of binary Logistic regression showed that anxiety ( OR=5.68, 95%CI =1.74- 18.55 ) and stress ( OR=5.41, 95%CI =2.20-13.32) were positively correlated with the occurrence of food addiction in primary and secondary school students ( P <0.01).@*Conclusions@#The risk of food addiction among primary and secondary school students with anxiety and stress symptoms is higher than that of the general population. Guidance and intervention on student mental health should cover the entire compulsory education and high school period, in order to improve the mental health level of students and reduce the occurrence of food addiction behavior.
