ObjectiveTo study the effect of Taikong Yangxin Pills on the metabolism of simulated weightless rats based on metabolomics and discuss the metabolism mechanism. MethodsIn the simulated space capsule environment on the ground, the rat model of simulated weightlessness was established by the tail suspension method. Rats were randomly grouped as follows: out-of-capsule control, in-capsule control, model, and high (3.0 g·kg-1) and low (1.5 g·kg-1) doses of Taikong Yangxin Pills, and they were administrated with corresponding drugs by gavage for 28 days. The serum levels of endogenous metabolites in rats were determined by ultra-performance liquid chromatography-quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS). The obtained data were processed by principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA) to screen for differential metabolites and potential biomarkers. MetaboAnalyst 5.0 was used for pathway enrichment analysis to explain the metabolic regulation mechanism of the drug. ResultsCompared with the out-of-capsule control group, the in-capsule control group showed elevated levels of thirteen metabolites, including 14-hydroxyhexadecanoic acid, linoleic acid, and α-linolenic acid (P<0.05), which suggested that the space capsule environment mainly affected the metabolism of α-linolenic acid and linoleic acid in the rats. Compared with the in-capsule control group, the model group showed lowered levels of fourteen metabolites, including 4-imidazolone-5-propionic acid, isocitric acid/citric acid, and L-tyrosine (P<0.05), which were recovered after the treatment with Taikong Yangxin pills (P<0.05). The pathway enrichment analysis revealed that weightlessness induced by tail suspension and drug intervention mainly involved the phenylalanine, tyrosine, and tryptophan biosynthesis, tyrosine metabolism, histidine metabolism, and citric acid cycle. ConclusionThe simulated space capsule environment and simulated weightlessness induced by tail suspension can both affect the metabolism level of rats. Taikong Yangxin pills can ameliorate the metabolic abnormality in the rat model of weightlessness by regulating various amino acids and energy metabolism-related pathways.

BackgroundIn recent years, the prevalence of obstructive sleep apnea (OSA) is escalating in China, leading to a serious disease burden. However, previous studies on the influencing factors of OSA, such as obesity and sleep position, were mostly cross-sectional studies. This approach inherently hinders the identification of dynamic interaction mechanism among multiple variables, consequently obstructing the formulation of individualized intervention strategies. ObjectiveTo investigate the differences in body mass index (BMI)-oxygen saturation-sleep position-heart rate variability (HRV) network models between OSA and non-OSA populations, thereby offering a reference for the early detection and management of OSA. MethodsA total of 384 adult participants undergoing sleep monitoring at the Affiliated Hospital of Southwest Medical University from July 12, 2022 to October 11, 2023 were included. Subjects were categorized into OSA group (n=203) and control group (n=181) based on an apnea-hypopnea index (AHI) threshold of 5 events per hour. Subsequently, BMI-oxygen saturation-sleep position-HRV networks were constructed and compared between two groups. ResultsThere was no significant difference in the overall edge weight (P=0.55) and overall strength (P=0.28) of the network model between control group and OSA group. Notable differences emerged in both the node connection strength (e.g., minimum oxygen saturation with BMI, sleep in prone position, and mean RR interval) and node centrality indices (mean oxygen saturation, minimum oxygen saturation, AHI in upright position, AHI in right lateral position and mean heart rate) within the two network models (P<0.05). ConclusionSignificant differences are observed between the non-OSA and OSA populations in specific factors, including sleep position, heart rate and oxygen saturation.

Objective:To investigate the expression characteristics of plasma proteins in patients with acute diquat poisoning by proteomic technology, and to screen the targets and biomarkers related to the diagnosis, treatment and prognosis of acute diquat poisoning.Methods:This study was a retrospective case-control study. Patients with diquat poisoning admitted to Nanjing University Affiliated Drum Tower Hospital from August 2022 to December 2023 were enrolled. Healthy volunteers matched for age and gender during the same period were selected as the control group. The general clinical data and plasma samples were collected, and qualitative and quantitative analyses of plasma proteins were performed by proteomic technology based on nanoliter liquid chromatography tandem quadrupole time-of-flight mass spectrometry. Mann-Whitney U test was used to compare differences of plasma protein expression between the two groups. Results:A total of 8 diquat poisoning patients and 7 healthy individuals were included in this study, and 491 plasma proteins were identified. Compared with control group, 76 differentially expressed proteins were obtained from the poisoned group, including 35 up-regulated proteins and 41 down-regulated proteins. GO analysis showed that the differentially expressed proteins were mainly associated with oxygen transporter activity, receptor binding, and hyaluronic acid-binding endopeptidase inhibitor activity. KEGG pathway enrichment analysis revealed that differentially expressed proteins were associated with complement and coagulation cascades, neutrophil extracellular trap formation, and platelet activation. In addition, the expression of adiponectin (ADIPOQ) was not only increased in poisoned patients, but also significantly higher in non-survivors than in survivors ( P<0.01). Conclusions:Multiple plasma proteins with abnormal expression may be involved in the pathological process of acute diquat poisoning. ADIPOQ may have potential application value in the diagnosis, treatment, and prognosis of acute diquat poisoning.

Objective:
To investigate the incidence trend of sexually transmitted diseases (STDs) in Yantian District, Shenzhen City, Guangdong Province from 2008 to 2022, and the effects of age, period, and cohort on STDs incidence, so as to provide the basis for formulating control measures for STDs.
Methods:
Data of reported STDs cases (syphilis, gonorrhea, genital Chlamydia trachomatis infections, condyloma acuminatum and genital herpes) among population aged 15 to 64 years in Yantian District from 2008 to 2022 were collected through the Chinese Disease Control and Prevention Information System. The temporal and population distribution of STDs were descriptively analyzed. Trends in incidence of STDs were analyzed using average annual percent change (AAPC). Impacts of age, period and cohort on the incidence of STDs were analyzed by an age-period-cohort model.
Results:
A total of 6 156 cases of STDs aged 15 to 64 years were reported from 2008 to 2022, and the average annual incidence was 229.92/105. The overall incidence showed an upward trend (AAPC=2.409%, P<0.05), and an upward trend among females (AAPC=5.846%, P<0.05), but the trend was not statistically significant among males (AAPC=0.193%, P>0.05). The incidence of STDs showed an increasing trend followed by a decreasing trend with the increase of age. The incidence trend among males was consistent with the overall population, reaching its peak in the age group of 30 to 34 years (371.04/105), while the incidence among females showed an increasing trend with the increase of age, peaking in the age group of 60 to 64 years (442.15/105). Compared with 2013-2017, the incidence risk of STDs showed an increasing trend in 2018-2022 (RR=1.349, 95%CI: 1.217-1.495). Compared with the birth cohort of 1975-1979, the incidence risk of STDs in 1980-2005 birth cohort showed an increasing trend, with the highest incidence risk in 2000-2004 birth cohort (RR=4.178, 95%CI: 2.717-6.423).
Conclusions
The overall incidence of STDs among residents aged 15 to 64 years in Yantian District from 2008 to 2022 appeared a tendency towards a rise. Age, period and cohort all had impacts on the incidence, with a greater effect among females than males.

Maternal depression can cause physical and mental harm to herself. This condition can lead to poor physical development in early offspring (newborns). However, the effect of maternal depression on the long-term physical development of offspring remains controversial. Studies have shown that offspring exposed to maternal depression in developed countries are at an increased risk of obesity. In view of the high incidence of maternal depression and childhood obesity in China, this article reviews the correlation between maternal depression and offspring obesity, aiming to provide insights for relevant research in China and offer references for the prevention and intervention of maternal depression and childhood obesity.

Objective :
To investigate the prevalence of occupational injury and identify its influencing factors among workers in a steel enterprise in Gansu Province, so as to provide insights into prevention of occupational injury among steel workers.
Methods:
Workers were sampled from a steel enterprise in Gansu Province using a cluster sampling method from January to March 2022, and participants' demographics, occupational history and occupational injury were collected using questionnaire surveys. The type of job and site and type of injury were analyzed among workers with occupational injuries, and factors affecting workers' occupational injuries were identified using a multivariable logistic regression model.
Results:
A total of 12 089 questionnaires were allocated and 10 725 valid questionnaires were recovered, with an effective recovery rate of 88.71%. The respondents included 9 412 males (87.77%) and 1 312 females (12.23%), and had a median age of 36.00 (interquartile range, 15.00) years. Junior college and above was the predominant educational level (6 056 workers, 56.47%), and the respondents had a median length of service of 10 (interquartile range, 11) years. The prevalence of occupational injury was 5.25% among respondents. Overhaul worker was the main type of job (11.90%), and object strike was the predominant type of occupational injury (18.25%), while the lower limb was the predominant site of injury (27.82%). Multivariable logistic regression analysis identified men (OR=2.464, 95%CI: 1.580-3.843), age (30 to 39 years, OR=2.561, 95%CI: 1.643-3.993; 40 to 49 years, OR=5.197, 95%CI: 2.679-10.079; 50 years and older, OR=10.620, 95%CI: 6.788-16.615), exposure to high temperature (OR=1.400, 95%CI: 1.165-1.683), operating equipment failure (OR=1.291, 95%CI: 1.048-1.591), absence of personal safety protection equipment (OR=1.555, 95%CI: 1.064-2.273) and safety behavior scores (OR=0.967, 95%CI: 0.937-0.996) as factors affecting occupational injuries among workers in a steel enterprise.
Conclusions
Men and overhaul workers are at a high risk of occupational injuries in this steel enterprise. Objectstrike is the predominant type of injury and lower limb is the main site of injury. The risk of occupational injuries is affected by gender, age, working environments, equipment status and safety behaviors.
