Objective: To analyze the correlation between preschool children s emotional competence and home rearing environment in Shangrao City, so as to provide support for improving children s emotional competence development as well as their home rearing environment. Methods: A total of 1 242 children aged 3-6 years old from 10 kindergartens in Shangrao City were retrospectively investigated by stratified cluster random sampling method in December 2022, and the Children s Emotional Adjustment Scale-Preschool Version (CEAS-P) and the Home Nurture Environment Scale for children aged 3-6 were surveyed on parents of preschool children. The t-test was used to test the difference, Spearman correlation analysis and multiple linear regression were used to analyze the influencing factors of preschool children s emotional competence. Results: There were significant differences in emotional competence scores of preschool children for demographic indicators including age, place of residence, health status and whether they were only children ( F/t =5.98, 6.56, 38.00, 2.23, P <0.01). The emotional competence of preschool children was positively correlated with the home rearing environment ( r=0.62, P <0.01). Multiple linear regression analysis showed that diverse activities/play participation, social adaptation/self management, and emotional warmth/self expression in home rearing environment were positive predictors of children s emotional ability ( β =0.30, 0.28, 0.16), while neglect/intervention/punishment were negative predictors ( β =-0.09)( P <0.05). Conclusions The home rearing environment is a factor related to young children s emotional competence. It is suggested specific parenting initiatives such as enriching family activities and play, strengthening children s self adaptation and management, giving warmth and let children express emotions, and preventing child neglect, interference and punishment should be conducted to improve children s emotional competence.

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 monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

Objective To study the pharmacokinetics of HMS-01 in mice and provide support for subsequent studies. Methods Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to establish a sensitive and specific method for the determination of the concentration of HMS-01 in plasma and other biological samples. The pharmacokinetics of HMS-01 in C57BL/6J mice were studied by the established method. To obtain the basic pharmacokinetic parameters, three doses of HMS-01 were given orally and one dose of HMS-01 was given intravenously. Results The pharmacokinetic results of mice showed that the intestinal absorption of HMS-01 was fast, the oral bioavailability of HMS-01 in mice was moderate (50% to 70%). The exposure levels (AUC and c_max) of HMS-01 in mice increased with the increase of dosage, while the AUC was linearly correlated with the increase of dosage. After intravenous administration of HMS-01, the half-life period in mice was about 1 h which was not long. The plasma clearance rate (CL_total.p) was 2.8 L/h·kg, which was similar to the hepatic blood flow of mice. The apparent volume of distribution (V_SS) was 5 L/kg, which was much larger than the total mouse fluid. There were significant differences in AUC and F (P<0.05), but no significant differences in parameters such as c_max,AUC_0−∞,t_1/2,CL_tot,p,MRT,Vss in male and female mice which were given 30 and 60mg/kg HWS-01 orally. Conclusion The pharmacokinetic process of HMS-01 in mice showed gender differences, and the area under the curve of blood concentration time and bioavailability of female mice were higher than that of male mice. As oral bioavailability was reasonable, further in vivo studies on HMS-01 in mice with heart failure by oral administration could be considered to provide evidence.

Heart failure (HF) is a global public health problem with high morbidity and mortality. Numerous studies have shown that HF is caused by severe disturbance of energy metabolism, resulting in insufficient cardiac energy supply. This lack of energy could lead to a failure of the heart to pump blood and a failure of energy metabolism in other organs throughout the body. Currently, therapeutics of HF work by reducing heart rate and cardiac preload and afterload, symptomatic treatment, or delaying the progression of the disease. However, drugs targeting heart energy metabolism have not been developed. the main characteristics of cardiac energy metabolism, metabolic changes during HF were summarized and drugs that improve cardiac function through energy metabolism were discussed, which could provide a new research direction for the development and application of drugs in treatment of heart failure.

Diabetic nephropathy (DN) is a common microvascular complication of type 1 diabetes mellitus (T1DM) and type 2 diabetes mellitus (T2DM)，which is also the main cause of chronic kidney disease (CKD) and end-stage renal disease (ESRD). However, the treatment methods are limited at present. More and more evidences have indicated that inflammatory response is involved in the pathogenesis and progression of DN. Several anti-inflammatory strategies that target specific inflammatory mediators (transcription factors, pro-inflammatory cytokines, chemokines, adhesion molecules) and intracellular signaling pathways have shown benefits in the DN rodent model. The mechanisms related to inflammation in the development and progression of DN were summarized and new strategies to prevent or treat DN based on inflammation were briefly discussed in this review.

Metabolic homeostasis is a basic function necessary for the survival of the organism. α₁-acid glycoprotein (AGP) is an acute phase protein with a glycosylation degree of up to 45%. It has high affinity and low capacity. Although the biological role of AGP is not fully understood, it has been proven that it can regulate immunity and metabolism, and play an important role in transporting drugs and maintaining capillary barrier function. In this review, the structural characteristics, biochemical characteristics and the regulation of AGP expression were reviewed, with emphasis on the regulatory role of AGP in metabolism, suggesting that AGP may be a potential key factor in metabolic pathways, which provides a new research direction for metabolic diseases.

Objective To test the cardiac toxicity of new compound HMS-01 and evaluate the safety profile for clinical trials. Methods Manualpatch clamp method was used to measure human Ether-a-go-go-Related Gene (hERG) potassium channel currents with different concentrations of HMS-01. Cisapride was selected as the positive control drug. HMS-01 was diluted to the concentration of 0.3, 1, 3, 10 and 30 µmol/L and applied to the cells. The changes in electrical currents were recorded and the inhibition rate was calculated. Results At the highest concentration of 30µmol/L, the inhibitory rate of HMS-01 on hERG channel was less than 30%. There was no obvious inhibitory effect compared with cisapride. Conclusion Compared with the cisapride, HMS-01 has no obvious inhibitory effect on hERG channel and has no cardiotoxicity.

α7 nicotinic acetylcholine receptor (α7nAChR) belongs to nicotinic acetylcholine receptors (nAChRs), which is the key receptor in cholinergic anti-inflammatory pathway and plays an important role in the neural regulation of immune system. Recent studies have found that α7nAChR is also involved in the regulation of various physiological and pathological processes other than immunity, such as non-alcoholic fatty liver, angiogenesis, heart protection, etc. In addition, α7nAChR is closely related to energy metabolism in neurodegenerative diseases. This article reviews the role of α7nAChR in treating inflammation and improving energy metabolism, and the new direction of α7nAChR involved in therapy.
