Objective: To explore the relationship between beverage dependence and sleep quality among college students, providing empirical evidence for improving their sleep quality. Methods: From December 2024 to January 2025, a convenience sampling method was used to conduct a questionnaire survey among 3 974 college students from four universities in Anhui Province. The Beverage Addiction Scale for College Students (BASCS) was used to assess beverage dependence, and the Self rating Scale of Sleep(SRSS) was used to evaluate sleep quality. A multivariate Logistic regression model was employed to analyze the relationship between beverage dependence and sleep quality, and a restricted cubic spline model was used to examine the dose response relationship between the two. Results: The positive rate of beverage dependence symptoms among college students was 7.6%, with positive rates of 9.6%, 13.8%, and 7.4% for the withdrawal symptoms, health effects, and dependence symptoms dimensions, respectively. The detection rate of sleep disorders was 23.6%. Multivariate Logistic regression analysis showed that after adjusting for covariates such as grade, gender, and body mass index, compared with the no beverage dependence group, students with positive beverage dependence symptoms had a higher risk of sleep disorders( OR =3.71, 95% CI =2.87-4.80, P <0.01). The OR (95% CI ) for sleep disorders among students with positive symptoms in the withdrawal symptoms, health effects, and dependence symptoms dimensions were 2.80(2.22-3.53), 2.38(1.95-2.91), and 2.45(1.89-3.18)(all P <0.01). Further analysis using a restricted cubic spline model revealed that the overall beverage dependence score and its three dimensional scores were approximately linearly related to the risk of sleep disorders among college students (all nonlinear P >0.05). Conclusions Beverage dependence is associated with sleep quality among college students. Schools should take multiple approaches, such as health education on beverage awareness, to improve students sleep quality.

Objective:To investigate the changes in interaction proteome of NUS1 mutant R290C and their relations with pathogenicity of Lennox Gastaut syndrome (LGS). Methods:The wild-type and mutant NUS1(R290C) plasmids were constructed and transfected into human embryonic kidney HEK293T cells; 48 h after that, NUS1 protein expression in HEK293T cells was detected by Western blotting. Co-immunoprecipitation, silver nitrate staining, and proteomic analysis were used to analyze the proteins interacted with wild-type or mutant NUS1 and identify the differential interacting proteins. Enrichment analyses of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were performed to annotate the molecular function and signaling pathways involved in the differential proteins. DisGeNet database was used to analyze the association between differential proteins and human diseases. Protein-protein interaction (PPI) was used to analyze the interaction network of NUS1 with protein folding regulatory proteins (RTN4 and DHDDS) and developmental epileptic encephalopathy related proteins.Results:(1) There was no significant difference in NUS1 protein expression between the wild-type and mutant NUS1 transfected HEK293T cells ( t=0.536, P=0.620). (2) Compared with that with wild-type NUS1 plasmid, number of proteins interacting with mutant NUS1 plasmid was significantly reduced in the transfected cells; 310 differential interacting proteins were screened in the mutant NUS1. (3) GO and KEGG enrichment analyses showed that the differential proteins were mainly involved in protein folding reaction and translation regulation. (4) DisGeNet association analysis showed that the two most relevant proteins in the differential interacting proteins were associated with frontotemporal dementia and developmental epileptic encephalopathy. (5) PPI analysis showed that NUS1 may be involved in occurrence of neurological diseases such as LGS by affecting protein folding signaling pathways. Conclusion:NUS1 mutant R290C alters its interacting protein lineage and mediates the development of LGS and other neurological diseases probably by regulating protein folding-related signaling.

During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.

Underactive bladder (UAB) belongs to the category of "urinary retention" and "urinary incontinence" in Traditional Chinese Medicine (TCM). Its pathogenesis is based on spleen qi deficiency and kidney deficiency, while dampness heat and blood stasis are the symptoms, and the nature of the disease is basedon the deficiency in nature and excess in superficiality and simultaneous occurrence of deficiency and excess syndrome. TCM treatment of UAB is mainly based on spleen qi deficiency syndrome, kidney deficiency syndrome, water and heat syndrome, deficiency and blood stasis syndrome to be treated with oral taken of Chinese materia medica, or the use of acupuncture, moxibustion, acupoint application and other external treatments, or the combination of acupuncture and medicine, TCM combined with rehabilitation training and other comprehensive treatments. All methods can improve the urodynamic indexes of patients, relieve symptoms and improve the quality of life, with certain efficacy.

Objective:To analyze the law of TCM syndrome differentiation and treatment for type 2 diabetic kidney disease (T2DKD) stage Ⅳ based on literature research.Methods:Literature on type 2 diabetic kidney disease stage Ⅳ was retrieved from CNKI, WanFang data, VIP and SinoMed database. The retrieval time was from the establishment of the databases to December 31, 2020. Data screening was conducted based on the inclusion and exclusion criteria prior to data entry in Microsoft Office Excel 365. Data mining and statistical analysis were performed by SPSS Statistics 23.0 and SPSS Modeler 18.1.Results:A total of 110 articles with 3 969 T2DKD stage Ⅳ cases, 111 prescriptions and 206 kinds of Chinese materia medica were included. Kidney and spleen were the main location of T2DKD stage Ⅳ. T2DKD stage Ⅳ based on TCM deficiency in nature syndrome was mainly based on qi and yin deficiency, and the most common excess in superficiality syndrome was blood stasis. The prescriptions commonly used included Liuwei Dihuang Decoction, Zhenwu Decoction, Buyang Huanwu Decoction, and Shenqi Dihuang Decoction etc. The classification of medication efficacy with the highest frequency was qi-tonifying herb, followed by blood-activating and stasis-resolving herb. Among them, Astragali Radix was the core Chinese materia medica in the prescription. The results of association rule obtained 54 association rules. Conclusions:The disease characteristics of T2DKD stage Ⅳ is simultaneous occurrence of deficiency and excess syndromes. The deficiency in nature is mainly characterized by deficiency of qi and yin, deficiency of spleen and kidney, deficiency of spleen-kidney yang, and excess in superficiality is mainly characterized by blood stasis, dampness and toxin. Tonifying qi and nourishing yin, activating blood circulation and dredging collaterals are the basic treatment methods, while strengthening spleen and kidney, dampness and detoxification should be emphasized. Astragali Radix, Angelicae Sinensis Radix, Salviae Miltiorrhizae Radix et Rhizoma, Poria, Dioscoreae Rhizoma, Corni Fructus, Rhei Radix et Rhizoma and Alismatis Rhizoma were the basic Chinese materia medica in this period, which reflects the idea of "treating qi, blood and water together".

Objective: To investigate the resuscitation effect of aortic balloon occlusion (ABO) on the traumatic cardiac arrest (TCA) in swine. Methods: Twenty-seven male domestic swine weighing (32.7±3.8)kg were utilized. After 40% of estimated blood volume was removed within 20 minutes, the animals were subjected to 5 minutes of untreated ventricular fibrillation and then 5 minutes of cardiopulmonary resuscitation. Additionally, fluid resuscitation was initiated coincident with the beginning of cardiopulmonary resuscitation. The animals were randomly divided into model group (n=12) and ABO group (n=15). Once cardiopulmonary resuscitation was implemented, aortic balloon was concurrently inflated to stop the blood flow of descending thoracic aorta at the level of the diaphragm in the ABO group. In the model group, aortic balloon was placed in the same position without inflation. During cardiopulmonary resuscitation, the changes of coronary perfusion pressure (CPP), forehead's regional cerebral oxygen saturation (rSO₂) and pressure of end-tidal CO₂ (PETCO₂) were continuously monitored, and the rate of return of spontaneous circulation (ROSC), duration of cardiopulmonary resuscitation, number of shocks and dose of epinephrine were recorded. At 5 minutes after successful resuscitation, the levels of arterial blood gas, lactate and jugular venous blood oxygen saturation (SjvO₂) were measured. Results: Compared with the model group, the values of CPP, rSO₂ and PETCO₂ during cardiopulmonary resuscitation were significantly increased in the ABO group [CPP: (33.5±5.6)mmHg vs. (23.1±5.2)mmHg at 1 minute, (35.3±6.0)mmHg vs. (26.8±7.4)mmHg at 2 minutes, (36.3±6.3)mmHg vs. (28.2±6.3)mmHg at 3 minutes, (40.1±7.1)mmHg vs. (30.5±6.2)mmHg at 4 minutes, (38.1±7.5)mmHg vs. (29.8±5.3)mmHg at 5 minutes; rSO₂: (45.4±5.2)% vs. (39.2±5.1)% at 1 minute, (47.2±3.6)% vs. (42.0±6.4)% at 2 minutes, (47.7±3.0)% vs. (41.5±5.4)% at 3 minutes, (47.0±2.5)% vs. (42.1±5.9)% at 4 minutes, (47.1±2.0)% vs. (41.5±7.4)% at 5 minutes; PETCO₂: (17.0±3.5)mmHg vs. (12.7±4.2)mmHg at 1 minute, (18.5±3.7)mmHg vs. (14.5±2.7)mmHg at 2 minutes, (20.7±5.3)mmHg vs. (15.5±3.2)mmHg at 3 minutes, (18.7±4.5)mmHg vs. (14.9±3.5)mmHg at 4 minutes, (18.2±3.2)mmHg vs. (14.5±4.2)mmHg at 5 minutes] (all P<0.05). The rate of ROSC was significantly higher in the ABO group than in the model group[100%(15/15) vs. 75%(9/12)] (P<0.05). Additionally, shorter duration of cardiopulmonary resuscitation, less number of shocks and lower doses of epinephrine were observed in the ABO group when compared with the model group[duration of cardiopulmonary resuscitation: 5(5, 5)minutes vs. 5(5, 12.5)minutes, number of shocks: 1(1, 1)times vs. 1(1, 4)times, dose of epinephrine: 0.62(0.62, 0.74)mg vs. 0.64(0.59, 2.59)mg] (all P<0.05). At 5 minutes after resuscitation, the level of arterial lactate was significantly decreased and the value of SjvO₂ was significantly increased in the ABO group compared with the model group[Lactate: (9.6±0.8)mmol/L vs. (10.8±1.4)mmol/L; SjvO₂: (50.0±8.6)% vs. (37.9±16.3)%] (both P<0.05). Conclusions In a swine model of TCA, ABO can increase cardiac and cerebral perfusion during cardiopulmonary resuscitation and improve the efficacy of cardiopulmonary resuscitation. It might provide a novel and effective method for the resuscitation of TCA in the clinical setting.

Objective To investigate the effects of dexmedetomidine postconditioning on brain injury after cardiac arrest and resuscitation in a swine model.Methods Twenty-eight healthy male domestic pigs,weighing 36±2 kg,were randomized (random number) into 4 groups (n=7 each group):sham operation group (S group),cardiopulmonary resuscitation group (CPR group),low-dose dexmedetomidine postconditioning group (LDP group),and high-dose dexmedetomidine postconditioning group (HDP group).Animals in the S group only underwent the surgical preparation.In the other three groups,the experimental model was established by 8 mins of electrically induced ventricular fibrillation and then 5 mins of cardiopulmonary resuscitation.At 5 min after resuscitation,a loading dose of dexmedetomidine of 0.25 μg/kg was intravenously infused followed by continuous infusion at a rate of 0.25 μg/(kg·h) for 6 h in the LDP group,and a loading dose of dexmedetomidine of 0.5 μ.g/kg was infused followed by continuous infusion at a rate of 0.5 μg/(kg·h) for 6 h in the HDP group.The same amount of normal saline was administered in the S and CPR groups.At 1 h,3 h,6 h and 24 h after resuscitation,the levels of serum neuron specific enolase (NSE) and S100B protein were measured.At 24 h after resuscitation,neurologic deficit score (NSD) was evaluated.After that,the animals were euthanized and cerebral cortex was obtained for the determination of tumor necrosis factor-α (TNF-α),interleukin-6 (IL-6)and malondialdehyde (MDA) contents,superoxide dismutase (SOD) activity,cell apoptosis and caspase-3 expression.Results Compared with the S group,post-resuscitation neurologic dysfunction and brain injury were observed in the other three groups,which were indicated by significantly higher NDS and markedly greater levels of serum NSE and S 100B (all P＜0.05).Compared with the CPR group,the score of NDS at 24 h post-resuscitation were significantly lower and the levels of serum NSE and S100B at 6 h and 24 h post-resuscitation were significantly less in the LDP and HDP groups [NDS:194±26,103±16 vs 278±23 at 24 h;NSE (ng/mL):32.4±1.8,28.6±3.7 vs 36.2±2.8 at 6 h,39.9±4.2,35.1±1.5 vs 45.1±3.0 at 24 h;S100B (pg/mL):2 534±207,2 382±170 vs 2 825±113 at 6 h,3 719±164,3 246±176 vs 4 085±161 at 24 h,all P＜0.05].Compared with the LDP group,neurologic dysfunction and brain injury at 24 h postresuscitation were further significantly alleviated in the HDP group (all P＜0.05).Pathological analysis indicated that brain inflammation,oxidative stress and cell apoptosis were observed after resuscitation in the CPR,LDP and HDP groups.However,the contents of TNF-α,IL-6 and MDA were significantly lower while the activity of SOD was significantly higher,and cell apoptosis and caspase-3 expression were significantly reduced in the brain after resuscitation in the LDP and HDP groups compared with the CPR group (all P＜0.05).In addition,those pathological injuries mentioned above were further significantly alleviated in the brain after resuscitation in the HDP group compared to the LDP group (all P＜0.05).Conclusions Dexmedetomidine postconditioning significantly alleviated the severity of postresuscitation brain injury in a dose-dependent manner,in which the protection was produced possibly through reducing tissue inflammation,oxidative stress and cell apoptosis.

Objective To investigate the appropriate age of primary and secondary school students for cardiopulmonary resuscitation (CPR) training.Methods A total of 437 students aged 9-15 years at 3 to 6 grade in the primary schools or 1 to 2 grade in the secondary schools were selected from 2 Yuyao primary and secondary schools by stratified random sampling between March 2017 and January 2018.The numbers of students with the age of 9,10,11,12,13,14 and 15 y were 61,62,66,64,63,63 and 58,respectively.All students received chest compression training provided by Yuyao emergency department People's Hospital according to the 2015 Cardiopulmonary Resuscitation Guidelines.The training included 30 min theoretic teaching and 6 min practice in the simulator.The quality of chest compression performed by students was assessed;the depth,rate,position and retention of chest compression were recorded.Results The mean depth of chest compression in the students aged 9-15 years was 3.8,4.1,4.6,5.1,5.2,5.6 and 5.6 cm,respectively;the accuracy rate was 24.6％(14/61),25.8％ (16/62),50.2％ (33/66),70.5％ (45/64),79.4％(50/63),88.9％(56/63) and 91.4(53/58),respectively.Compared with the students aged 9-11 years,the mean depth of chest compression was significantly increased and accuracy rate was significantly improved in the students aged 12-15 years (Compared with 9-y students,t=-8.936,-9.502,-10.640 and-11.370;x2=35.019,47.599,63.013 and 65.671;compared with 10-y students,t=-6.927,-8.179,-10.70 and-11.047;x2=24.977,35.967,50.916 and 52.727;compared with 1 1-y students,t=-3.095,-4.177,-6.785 and-6.995;x2=5.586,12.114,22.786 and 24.870;all P＜0.05).The mean rate of chest compression was 110-116/min and its accuracy rate was 86.4％-95.2％;the accuracy rate of chest compression position was 90.9％-96.8％ in all students,there were no significant differences among the 7 groups.The mean retention rate of chest compression in the 7 groups was 81.3％(122/150),67.3％(101/150),64.7％ (94/150),48.0％(72/150),48.7％(73/150),33.3％(50/150) and 27.3％(41/150),respectively.Compared with the students aged 9-11 years,the mean retention rate of chest compression was significantly decreased in the students aged 12-15 years (compared with the 9-y students,x2=36.472,35.179,70.64 and 119.92;compared with 10-y students,x2=11.483,10.728,34.682 and 72.150;compared with 11-y students,x2=6.528,5.927,25.855 and 59.11;all P＜0.05).Correlation analysis showed that the depth (r=0.96,0.89,0.91 and 0.86;P＜0.01) and retention rate (r=-0.99,-0.90,-0.93 and-0.86;all P＜0.01) of chest compression were significantly associated with the age,body weight,height and body mass index of students.Conclusion The students with an age of 12 years or more are able to effectively perform chest compression;thus,12 years and above might be the appropriate age for CPR training.

Objective To evaluate the effect of dexmedetomidine on receptor-interacting protein 1 (RIP1) signaling pathway during brain injury after cardiac arrest and resuscitation in pigs.Methods Twenty-one healthy domestic male white pigs,weighing 33-41 kg,were divided into 3 groups (n =7 each) using a random number table method:sham operation group (group S),cardiac arrest-resuscitation group (group CA-R) and dexmedetomidine group (group D).Ventricular fibrillation was electrically induced and untreated for 8 min followed by 5 min of cardiopulmonary resuscitation to establish the model of brain injury after cardiac arrest and resuscitation in anesthetized domestic white pigs.Dexmedetomidine was infused via the femoral vein in a loading dose of 0.5 μg/kg at 5 min after successful resuscitation,followed by an infusion of 0.5 μg · kg-1 · h-1 for 6 h in group D.The equal volume of normal saline was given instead in S and CA-R groups.The concentrations of neuron-specific endase (NSE) and S-100β protein in serum were measured at 1,3,6 and 24 h after resuscitation (T1-4).Neurologic deficit score (NDS) was evaluated at T4.The animals were sacrificed at T4,brains were removed and cerebral cortex tissues were obtained for determination of the expression of RIP1,RIP3 and mixed lineage kinase domain-like protein (MLKL) by Western blot.Results Compared with group S,the serum concentrations of NSE and S-100β protein were significantly increased at T1-4,the NDS was increased at T4,and the expression of RIP1,R1P3 and MLKL in cerebral cortex tissues was up-regulated in CA-R and D groups (P＜0.05).Compared with group CA-R,the serum concentrations of NSE and S-100β protein were significantly decreased at T3,4,the NDS was decreased at T4,and the expression of RIP1,RIP3 and MLKL in cerebral cortex tissues was down-regulated in group D (P＜0.05).Conclusion The mechanism by which dexmedetomidine reduces brain injury after cardiac arrest and resuscitation may be related to inhibiting the activation of RIP 1 signaling pathway in pigs.
