ObjectiveTo investigate the potential value of thyroid hormones in cerebrospinal fluid in predicting autism-like behaviors induced by hypothyroidism in pregnant rats. MethodsTwelve pregnant Wistar rats were randomly divided into a control group and a hypothyroidism group (hypothyroidism model group). Offspring from both groups had serum and cerebrospinal fluid levels of thyroid-stimulating hormone (TSH), total triiodothyronine (TT3), total thyroxine (TT4), free triiodothyronine (FT3), and free thyroxine (FT4) levels in serum and cerebrospinal fluid. Ultrasonic vocalization tests were conducted on postnatal day 2 (P2), day 7 (P7), and day 14 (P14), while behavioral tests using the three-box social interaction test were performed on day 21(P21). ResultsCompared with the control group, free T4 (FT4) levels in the cerebrospinal fluid of the hypothyroidism group were significantly reduced during the developmental period (P0-P21; P2: P<0.05; P7: P<0.05; P14: P<0.01; P21: P<0.01), with no statistical difference between the two groups only at P0 (P>0.05). In the ultrasonic vocalization (USV) tests, the number and duration of USVs in offsprings from the hypothyroidism group were significantly reduced compared with those of the control group on P2, P7 and P14: for USV counts (P2: P<0.05; P7: P<0.001; P14: P<0.01); for USV duration (P2: P<0.05; P7: P<0.001; P14: P<0.001). In the three-box social tests, offsprings of the hypothyroidism group showed significantly reduced sniffing time with unfamiliar rats at P21 compared to the control group (all P<0.001). The FT4 levels in cerebrospinal fluid had a significantly positive correlation with USV counts (P7: r=0.883, P<0.05; P14: r=0.902, P<0.05) and sniffing time with unfamiliar rats (r=0.814, P<0.01). ConclusionMeasuring free T4 in cerebrospinal fluid can predict autism-like behaviors in offsprings of rats induced by hypothyroidism during pregnancy.

Objective:
To analyze the association between poor sleep characteristics and the coexistence of negative emotions and overweight/obesity among college students, so as to provide a scientific basis for improving their physical and mental health.
Methods:
From November to December 2023, a convenience sampling method was used to survey 6 600 college students from nine universities in Jiangxi, Hunan, and Hubei provinces. The Depression Anxiety and Stress Scale-21 (DASS-21), Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and physical examinations were employed to assess negative emotions, poor sleep characteristics, and overweight/obesity. Chi square test and Logistic regression were used to analyze the impact of poor sleep characteristics on the coexistence of negative emotions and overweight/obesity.
Results:
The coexistence rates of different categories of negative emotions (depression, anxiety, stress) and overweight/obesity were 6.1% ( n= 405), 8.0% ( n =529), and 3.3% ( n =217), respectively. Gender, grade level, major, maternal education level, annual family income, physical activity level, only child status, and carbonated beverage consumption were statistically associated with the coexistence rates of different categories of negative emotions and overweight/obesity ( χ 2=4.01-35.18, all P <0.05). Logistic regression analysis showed that after adjusting for gender, grade level, major, only child status, maternal education level, annual family income, physical activity level, and carbonated beverage consumption, poor sleep characteristics were significantly associated with an increased risk of the coexistence of negative emotions and overweight/obesity ( OR =1.41-6.65); moderate and poor sleep quality levels were significantly associated with an increased risk of the coexistence of different categories of negative emotions and overweight/obesity among female students ( OR =1.99-4.71) (all P <0.05).
Conclusions
Poor sleep characteristics are associated with the coexistence of negative emotions and overweight/obesity among college students. Greater attention should be paid to sleep issues in this population, and sleep education should be actively promoted to reduce the risk of comorbid negative emotions and overweight/obesity.

OBJECTIVES:
To explore the effects of cannabidiol on endoplasmic reticulum stress and neuronal apoptosis in rats with multiple concussions (MCC).
METHODS:
SD rats were randomized into sham group, MCC group, 1% tween20 (TW) treatment group, and low-dose (10 mg/kg) and high-dose (40 mg/kg) cannabidiol treatment groups. In all but the sham group, MCC models were established using a metal pendulum percussion device, after which the rats received daily intraperitoneal injections of the corresponding agents for 2 weeks. The expressions of PERK, eIF2α, ATF4, CHOP, TRIB3, p-Akt and pro-caspase-3 in the brain tissue of the rats were detected with qRT-PCR, Western blotting and immunofluorescence staining. The core targets of cannabidiol in treatment of traumatic brain injury (TBI) were identified by network pharmacology analysis, and molecular docking was carried out to simulate the interaction of cannabidiol with the factors related to endoplasmic reticulum stress and apoptosis.
RESULTS:
Compared with the sham-operated rats, the rat models of MCC showed significantly increased mRNA expressions of PERK, eIF2α and CHOP and protein expressions of PERK, eIF2α, ATF4, CHOP, TRIB3, p-AKT and pro-caspase-3 in the cerebral cortex. CBD treatment, especially at the high dose, obviously increased the expression of p-Akt and lowered the expression levels of the other factors tested in the rat models. Network pharmacology analysis indicated interactions of the core targets of CBD with the factors related to endoplasmic reticulum stress and TBI, and molecular docking study showed a high binding energy of CBD with multiple factors pertaining to endoplasmic reticulum stress and apoptosis.
CONCLUSIONS
MCC induce endoplasmic reticulum stress and apoptosis in rat brain tissues, for which CBD, especially at a high dose, provides neuroprotective effects by inhibiting endoplasmic reticulum stress and cell apoptosis.

Autism Spectrum Disorders (ASDs) are reported as a group of neurodevelopmental disorders. The structural changes of brain regions including the hippocampus were widely reported in autistic patients and mouse models with dysfunction of ASD risk genes, but the underlying mechanisms are not fully understood. Here, we report that deletion of Trio, a high-susceptibility gene of ASDs, causes a postnatal dentate gyrus (DG) hypoplasia with a zigzagged suprapyramidal blade, and the Trio-deficient mice display autism-like behaviors. The impaired morphogenesis of DG is mainly caused by disturbing the postnatal distribution of postmitotic granule cells (GCs), which further results in a migration deficit of neural progenitors. Furthermore, we reveal that Trio plays different roles in various excitatory neural cells by spatial transcriptomic sequencing, especially the role of regulating the migration of postmitotic GCs. In summary, our findings provide evidence of cellular mechanisms that Trio is involved in postnatal DG morphogenesis.

In the context of continuously deepening medical and health system reforms and comprehensively promoting the "Healthy China" strategy, Henan Provincial People's Hospital has established a regional collaborative and vertically integrated critical care service structure and network. This initiative aims to enhance information empowerment, strengthen regional collaboration, improve the insufficient primary medical services, and ensure timely and effective treatment for critically ill patients. By establishing a comprehensive dispatch service platform for regional collaborative critical care, building a "top-down" remote medical collaboration network, and forming a cross-regional specialty alliance for critical care, the hospital has improved the efficiency of medical services and enhanced regional capabilities for treating critically ill patients. Simultaneously, for critically serious patients and those with complex diseases at primary medical institutions, a one-stop consultation and referral service has been implemented. This service adopts a "three specialists" approach and a multidisciplinary consultation mechanism within the hospital, constructs a multi-dimensional critical care transfer mode integrating air, ground, and the internet, creates a regional collaborative rescue mode, and implements full-cycle treatment for critically serious patients. The comprehensive, flexible, and efficient service pathway for regional collaborative critical care established by this system ensures timely and safe treatment for critically ill patients, promotes the distribution of high-quality medical resources, and effectively addresses issues such as uneven distribution of high-quality medical resources and varying levels of critical care capabilities. It has facilitated the formation of a new tiered diagnosis and treatment order characterized by "first diagnosis at the primary level, two-way referral, separate treatment for acute and chronic diseases, and vertical integration". This approach has enhanced the diagnostic and comprehensive service capabilities of primary medical institutions. Currently, by strengthening information empowerment and sharing, creating a full-process critical care diagnosis and treatment model, providing medical assistance and cultivating primary-level critical care talent, and promoting appropriate technologies, the hospital has gradually overcome challenges such as barriers to information exchange and sharing between hospitals, overloaded critical care teams, high pressure on patient reception and transfer, and limited critical care capabilities at primary medical institutions. This article summarizes the construction and practical application of this regionally coordinated critical care system, aiming to provide a reference for the management of critical care treatment.

In ground-based experiments,ultraviolet irradiation is used to charge simulated lunar dust,aiming to quantitatively study its charging and discharging behavior in space environments.However,due to factors such as vacuum and dust disturbances,the charging and discharging processes of lunar dust are difficult to measure accurately through contact methods.Therefore,this paper designs and constructs a non-contact,in-situ surface potential measurement system based on the principle of vibrating capacitance,suitable for vacuum environments.The system combines moving average and standard deviation methods for data filtering and introduces a weighted KNN algorithm to predict and compensate for missing or anomalous data,thereby improving measurement accuracy and stability.Two typical simulated lunar dust samples,TYII-2 and CLRS-1A,were selected for charging and discharging experiments under ultraviolet irradiation.The surface potential distribution was obtained in real-time using an in-situ motion mechanism equipped with a vibrating capacitance sensor.The results show significant differences in the charging response and dissipation characteristics of the samples with different particle size distributions.

Breast cancer has become the malignant tumor with the highest incidence rate. Although the emergence of new drugs has prolonged the overall survival of breast cancer patients, it still possesses a high recurrence and metastasis rate due to tumor heterogeneity and drug resistance. Glucose is the main source of energy metabolism for breast cancer cells, and the glucose metabolism of breast cancer cells is significantly different from that of normal breast cells. The high energy demand and rapid growth of breast cancer cells make their demand for glucose much higher than that of normal cells. Moreover, even under aerobic conditions, the glycolytic effect of breast cancer cells will be significantly enhanced to meet the high energy metabolism demand of breast cancer cells. The main reason for the enhanced glycolytic effect of breast cancer cells is the enhanced activity of glycolysis-related enzymes and regulatory factors, including pyruvate kinase, hexokinase, phosphofructokinase, lactate dehydrogenase, and glucose transporter protein. The metabolism process of glycolysis in breast cancer cells can be regulated by interfering with the activity of these enzymes and regulatory factors, thus inhibiting the proliferation of breast cancer, promoting apoptosis, and reversing drug resistance, invasion, and metastasis. Traditional Chinese medicine (TCM) has a long history of treating breast cancer and has made significant achievements in the aspects of anti-recurrence, metastasis, and drug resistance. In recent years, more and more research related to the intervention of aerobic glycolysis in breast cancer by TCM monomers, single-flavored TCM, and compounds has been conducted and has made great achievements. In addition, a large number of in vivo and in vitro experiments have shown that aerobic glycolysis is an important potential target for the treatment of breast cancer by TCM, but there is a lack of a comprehensive review and summary. On this basis, this paper elaborated on the roles of key targets in aerobic glycolysis and breast cancer and summarized the relevant studies on the treatment of breast cancer by intervention of glycolysis with TCM, with a view to providing new ideas for further research.
