OBJECTIVES: To investigate the relationship between the polygenic risks for various psychiatric disorders and clinical and neuropsychological characteristics in children with attention-deficit/hyperactivity disorder (ADHD). METHODS: Using a cross-sectional design, 285 children with ADHD and 107 healthy controls were assessed using the Child Behavior Checklist, the Behavior Rating Inventory of Executive Function for parents, the Wechsler Intelligence Scale for Children, Fourth Edition, and the Cambridge Neuropsychological Test Automated Battery. Blood samples were collected for genetic data. Polygenic risk scores (PRSs) for various psychiatric disorders were calculated using the PRSice-2 software. RESULTS: Compared with the healthy controls, the children with ADHD displayed significantly higher PRSs for ADHD, major depressive disorder, anxiety disorder, and obsessive-compulsive disorder (P<0.05). In terms of daily-life executive function, ADHD-related PRS was significantly correlated with the working memory factor; panic disorder-related PRS was significantly correlated with the initiation factor; bipolar disorder-related PRS was significantly correlated with the shift factor; schizophrenia-related PRS was significantly correlated with the inhibition, emotional control, initiation, working memory, planning, organization, and monitoring factors (P<0.05). The PRS related to anxiety disorders was negatively correlated with total IQ and processing speed index (P<0.05). The PRS related to obsessive-compulsive disorder was negatively correlated with the processing speed index and positively correlated with the stop-signal reaction time index of the stop-signal task (P<0.05). CONCLUSIONS PRSs for various psychiatric disorders are closely correlated with the behavioral and cognitive characteristics in children with ADHD, which provides more insights into the heterogeneity of ADHD.

Hemorrhagic shock is a common clinical emergency that can aggravate cell injury after resuscitation. Astrocytes are crucial for the survival of neurons because they regulate the surrounding ionic microenvironment of neurons. Although hemorrhagic shock and resuscitation (HSR) injury can impair cognition, it remains unclear how this insult directly affects astrocytes. In this study, we established an HSR model by bleeding and re-transfusion in mice. The social interaction test and new object recognition test were applied to evaluate post-operative cognitive changes, and the results suggest that mice experience cognitive impairment following exposure to HSR. In the HSR group, the power spectral density of β and γ oscillations decreased, and the coupling of the θ oscillation phase and γ oscillation amplitude was abnormal, which indicated abnormal neuronal oscillation and cognitive impairment after HSR exposure. In brief, cognitive impairment in mice is strongly correlated with Ca²⁺ signal strength in lateral septum astrocytes following HSR.

OBJECTIVES: To characterize fine particulate matter (PM _2.5)-bound polycyclic aromatic hydrocarbons (PAHs) emitted from different cooking fumes and their exposure routes and assess their health-associated impact to provide a reference for health risk prevention from PAH exposure across different age and sex groups. METHODS: Sixteen PM _2.5-bound PAHs emitted from 11 cooking styles were analyzed using GC-MS/MS. The health hazards of these PAHs in the Handan City population (stratified by age and sex) were predicted using the incremental lifetime cancer risk ( ILCR) model. The respiratory deposition doses ( RDDs) of the PAHs in children and adults were calculated using the PM _2.5 deposition rates in the upper airway, tracheobronchial, and alveolar regions. RESULTS: The total concentrations of PM _2.5-bound PAHs ranged from 61.10 to 403.80 ng/m ³. Regardless of cooking styles, the ILCR _total values for adults (1.23 × 10 ^-6 to 3.70 × 10 ^-6) and older adults (1.28 × 10 ^-6 to 3.88 × 10 ^-6) exceeded the acceptable limit of 1.00 × 10 ^-6. With increasing age, the ILCR _total value first declined and then increased, varying substantially among the population groups. Cancer risk exhibited particularly high sensitivity to short exposure to barbecue-derived PAHs under equivalent body weights. Furthermore, barbecue, Sichuan and Hunan cuisine, Chinese cuisine, and Chinese fast food were associated with higher RDDs for both adults and children. CONCLUSION ILCR _total values exceeded the acceptable limit for both females and males of adults, with all cooking styles showing a potentially high cancer risk. Our findings serve as an important reference for refining regulatory strategies related to catering emissions and mitigating health risks associated with cooking styles.

Chronic pelvic inflammatory disease(CPID)is a common chronic inflammatory disease in women,and has a long course and is easy to relapse.Danggui Shaoyao Powder is from Jin Gui Yao Lve(Synopsis of the Golden Chamber),which was a commonly-used formula for the treatment of women's abdominal pain in ancient medical records.It is now often used in the treatment of CPID and has achieved satisfactory therapeutic effect.The article summarizes and analyzes the achievements in the clinical research and experimental study of Danggui Shaoyao Powder in the treatment of CPID over the past 10 years,and invesigates the clinical efficacy of Danggui Shaoyao Powder in the treatment of CPID and its therapeutic mechanism.In the field of clinical studies,Danggui Shaoyao Powder for the treatment of CPID was used by modification,or alone,or in combination with antibiotics and Chinese medicine external treatment,and its combined use was effective on significantly improving the indicators of inflammatory response and immune function,alleviating the clinical signs and symptoms such as pain,and did not increase the incidence of adverse reactions compared with the application of western medicines alone.In the field of experimental studies,Danggui Shaoyao Powder played the therapeutic role in CPID by decreasing the adhesion of endothelial cells,regulating the degradation of extracellular matrix,improving the level of inflammatory factors,and down-regulating the expression of proteins related to the nuclear factor κB(NF-κB)pathway.

Objective To investigate the relationship and potential pathways between metal(loid)exposure and the risk of polycystic ovary syndrome(PCOS)in women of childbearing age. Methods This case-control study included 200 patients with PCOS(cases)and 896 non-PCOS controls with the age of 25-37 years.The concentrations of 29 metal(loid)s in the follicular fluid(FF)and clinical indicators in the serum were measured in all participants.Logistic regression analysis and mediation analysis were conducted to evaluate the associations between metal(loid)exposure and PCOS risk and investigate the possible roles of clinical indicators,respectively. Results Logistic regression analysis revealed an association between high copper levels in FF and increased PCOS risk(highest vs.lowest quartile:adjusted odds ratio=2.94,95%confidence interval:1.83-4.72).A high luteinizing hormone/follicle-stimulating hormone ratio and elevated levels of testosterone and anti-Müllerian hormone(AMH)were strongly associated with increased PCOS risk induced by high copper exposure.The mediation analysis indicated a mediating effect of AMH in the association between copper exposure and PCOS risk. Conclusion Copper may affect PCOS risk through the hypothalamic-pituitary-ovarian axis,mediated by AMH.Copper exposure and internal AMH levels are important indicators for early warning of PCOS development.

Objective To investigate the ameliorative effects and potential mechanism of Lithocarpus litseifoliu on renal function and inflammation in mice with hyperuricemic nephropathy(HN).Methods The HN model was established by the combined administration of adenine and potassium oxyzate.The mice were randomly divided into normal control group,model control group,benzbromarone group,and high,medium and low dose groups of Lithocarpus litseifoliu.Different drugs were given to the mice,and their body mass was recorded once a week.The levels of uric acid(UA),creatinine(Cr),urine protein(UP),blood urea nitrogen(BUN)and urine urea nitrogen(UUN)as well as the levels of tumor necrosis factor α(TNF-α)and interleukin 6(IL-6)in serum or urine of each group were collected and measured on the 21st day.Hematoxylin-eosin(HE)staining was performed to observe kidney tissue injury in mice;real-time PCR(RT-PCR)was performed to determine ATP-binding cassette subfamily G member 2(ABCG2),urate transporter protein(URAT1),glucose transporter protein 9(GLUT9),and cytosolic factor NF-κB p50(κB p50)in kidney tissues.Results Compared with the normal control group,the body mass of mice in the model control group was significantly lower after the second weeks of modeling(P＜0.05),and the levels of UA,Cr,UP,BUN,UUN,TNF-α,IL-6 contents and GLUT9 mRNA and κB p50 mRNA expression contents of kidney tissues were significantly higher(P＜0.01,P＜0.05).Compared with the model control group,the levels of Cr,UP,BUN and UUN contents and renal tissue nuclear cytokine κB p50 mRNA expression were significantly lower in the high,medium and low dose groups of Lithocarpus litseifoliu(P＜0.01,P＜0.05).The UA levels were significantly lower in the high dose group of Lithocarpus litseifoliu(P＜0.05),and renal ABCG2 mRNA expression was significantly higher in the medium dose group(P＜0.01).The renal URAT1 mRNA expression was significantly decreased in the low dose group(P＜0.01).Conclusion Lithocarpus litseifoliu has shown ameliorative effects on HN mice,and the mechanism may be related to the modulation of renal uric acid transporters,improvement of renal function and anti-inflammation effects.

In the progression of end-stage liver disease,the incidence of sleep disorders in patients with liver cirrhosis is high.Currently,western medicine treatment has obvious liver and kidney damage and adverse reactions after discontinuation,which affects the therapeutic effect.Cirrhosis and sleep disorders can be separately attributed to the category of"abdominal mass"and"insomnia"in traditional Chinese medicine.The"abdominal mass"is caused by the disorder of liver and spleen qi movement,as well as the obstruction of phlegm-dampness and blood stasis.In the development of"abdominal mass",the liver failed in ensuring free movement of qi,the spleen failed in transportation and transformation,liver yin and liver blood became insufficiency and the imbalance of yin and yang in the zang-fu organs became imbalanced,and then the ethereal soul depart from the housing,which leads to"insomnia"as an outward manifestation.Professor ZHOU Xiao-Zhou focuses on the concept of qi and blood,and points out that the pathogenesis of sleep disorder in cirrhosis is characterized by liver stagnation and spleen deficiency.He proposed that the treatment principle is to regulate the liver and spleen simultaneously,as well as to nourish the heart and calm the mind.Professor ZHOU has developed Ganyinghua Anshen Formula for treating sleep disorders in cirrhosis,which is derived from the modification of Xiangsha Liujunzi Decoction,and is composed of 14 Chinese medicines of vinegar-prepared Cyperi Rhizoma,Amomi Fructus,Coicis Semen,Dioscoreae Rhizoma,bran-fried Atractylodis Macrocephalae Rhizoma,Galli Gigerii Endothelium Corneum,Gardeniae Fructus,Codonopsis Radix,Salviae Miltiorrhizae Radix et Rhizoma,Citri Reticulatae Pericarpium,Sclerotium Poriae Pararadicis,Longan Arillus,Albiziae Cortex,and Glycyrrhizae Radix et Rhizoma Praeparata cum Melle.The formula has achieved remarkable clinical effect.The clinical experience of Professor ZHOU Xiao-Zhou for treating sleep disorders in cirrhosis through regulating the liver and spleen simultaneously will provide a reference for its clinical treatment with traditional Chinese medicine.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To explore the construction and practical effects of a multidisciplinary collaborative nursing management model of"organization-training-emergency response-integration-quality control"for pan-vascular disease patients in integrated wards.Methods On the basis of literature research and expert meetings,a multidisciplinary collaborative nursing management model for patients with pan-vascular disease in intergrated wards has been formed.It includes the implementation of accurate dynamic and intelligent overall allocation of beds in the hospital,the formulation of multidisciplinary training programs,the establishment of an emergency and critical case treatment guarantee mechanism,the construction of a standardized path for the joint management of multidisciplinary nursing teams,and the establishment of an intelligent and homogeneous nursing quality control chain.From July 2022 to December 2023,the program was implemented in the cardio-cerebrovascular ward of a tertiary A hospital in Zhejiang province,and indicators such as the average length of stay,cure and improvement rate,and cardiopulmonary resuscitation success rate were collected,and the satisfaction of patients with pan-vascular disease was investigated.Results During the application of multidisciplinary collaborative nursing management model for patients with pan-vascular disease,5416 patients were admitted,with an average length of stay of 6.11±0.73 days,a cure and improvement rate of 98.06%(5 311/5 416),a cardiopulmonary resuscitation success rate of 94.12%,and no adverse events.The overall satisfaction score of patients improved from 92.74±1.68 points in the 4th quarter of 2022 to 98.21±0.55 points in the 4th quarter of 2023(P<0.001).Conclusion The construction of the multidisciplinary collaborative nursing management model in the integrated pan-vascular ward has explored a new path for the hospital to cultivate cross-professional nursing personnel,promoted effective resource integration,and optimized the health management path,effectively improved the utilization rate of existing resources in the hospital and patients'medical experience.
