Objective: To explore the intervention effects of high intensity interval training (HIIT) on glucose metabolism, cortisol (Cor), and sleep quality among college students with comorbid depressive symptoms and obesity, so as to provide a reference for improving sleep quality among college students with comorbid depressive symptoms and obesity. Methods: In March 2023, 45 college students with comorbid depressive symptoms and obesity were recruited and randomly assigned to an exercise group ( n =23) and a control group ( n =22) by random number table method. The exercise group received HIIT intervention for 12 weeks, three times a week, while the control group received no intervention. Blood samples were collected from participants to measure fasting insulin (FINS), fasting blood glucose (FBG), homeostatic model assessment of insulin resistance (HOMA-IR), Cor, and Pittsburgh Sleep Quality Index (PSQI) before and after intervention. Statistical analysis was performed using t-test, repeated measures analysis of variance (ANOVA), simple effect analysis. Results: The repeated measures ANOVA revealed statistically significant time×group interaction effects for body composition (weight, body mass index, percentage of body fat, fat mass, waist to hip ratio), depressive symptoms, PSQI scores and its subdimensions (subjective sleep quality, sleep onset time, sleep efficiency, sleep disorders, daytime dysfunction), as well as FBG, FINS, and HOMA-IR between the exercise group and control group before and after intervention ( F =7.10-53.38, all P <0.05). Simple effect analysis showed that compared to the control group, the exercise group demonstrated significant improvements in body composition (body mass index, fat mass, waist to hip ratio), depressive symptoms, PSQI scores and its sub dimensions (subjective sleep quality, sleep onset time, sleep efficiency, sleep disorders, daytime dysfunction), FBG, FINS, HOMA-IR, and Cor (all P <0.05). Conclusion HIIT can improve the sleep quality of college students with comorbid depressive symptoms and obesity by enhancing glucose metabolism and regulating Cor levels.

Objective: To investigate the association between emotional intelligence and sleep problems at the symptom level among junior and senior high school students, so as to provide new insights for interventions targeting junior and senior high school students sleep disorders. Methods: From November 2023 to May 2024, a stratified cluster random sampling method was employed to select 3 531 first year junior high school and first year senior high school students from 6 schools in Guangyuan City and Liangshan Yi Autonomous Prefecture in Sichuan Province, as well as Lhasa City in Tibet Autonomous Region. The Insomnia Severity Index Scale and the Wong and Law Emotional Intelligence Scale(WLEIS) were used to assess sleep problems and emotional intelligence. A network analysis was performed to explore the relationship between emotional intelligence and sleep disorders, and a gender based network comparison analysis was conducted. Results: The reported rate of sleep problems among junior and senior high school students was 47.3%, with severe sleep problems of 2.2%. Difficulty maintaining sleep, worry about sleep, and emotional application were the core symptoms in the network (node strength values: 1.11, 0.98, and 0.82, respectively). Dissatisfaction with sleep and emotional application served as bridge symptoms connecting emotional intelligence and sleep problems (bridge strength values: 1.77 and 1.59, respectively). The edge weights of the emotional intelligence and sleep problems network differed significantly between genders (maximum difference in edge weight values was 0.13， P <0.05). Conclusions Emotional application ability and dissatisfaction with sleep are the key nodes in the network connecting emotional intelligence and sleep problems. Targeted efforts to enhance emotional application ability may effectively reduce the risk of sleep problems among junior and senior high school students.

and blood stasis syndrome,and to explore their effect on serum levels of soluble cluster of differentiation 40 ligand(sCD40L),lipoprotein phospholipase A2(Lp-PLA2),and glycated albumin(GA).Methods A total of 117 patients with ICVD of qi deficiency and blood stasis syndrome were randomly divided into control group 1,control group 2,and study group,with 39 patients in each group.The three groups were all given basic treatment with agents of diuretic,lipid regulation,antiplatelet,and antihypertensive,and additionally,control group 1 was given Edaravone,control group 2 was given Zhi Long Huoxue Tongyu Capsules,and the study group was given Zhi Long Huoxue Tongyu Capsules combined with Edaravone.The course of treatment for the three groups covered 14 days.Before and after treatment,the three groups were observed in the changes of National Institutes of Health Stroke Scale(NIHSS)scores for neurological function,modified Barthel Index(MBI)scores for activities of daily living(ADL),cerebral hemodynamics indicators[peak systolic velocity(PSV),end-diastolic velocity(EDV),mean velocity(Vm),pulsatility index(PI),and resistance index(RI)],neurofactors[neuron-specific enolase(NSE),S100β protein(S100β),and myelin basic protein(MBP)],vascular endothelial function indicators[von Willebrand factor(VWF),endothelin 1(ET-1),and nitric oxide(NO)],and levels of serum sCD40L,Lp-PLA2,and GA.After treatment,the clinical efficacy and the incidence of adverse reactions among the three groups of patients were compared.Results(1)After 14 days of treatment,the total effective rate of the study group was 94.87%(37/39),which was significantly higher than that of control group 1[71.79%(28/39)]and control group 2[76.92%(30/39)],the differences being statistically significant(P<0.05).No statistically significant difference was shown between control group 1 and control group 2(P>0.05).(2)After treatment,the cerebral hemodynamics indicators of PSV,EDV,Vm,and PI of the middle cerebral artery(MCA)in the three groups were increased compared with those before treatment(P<0.05),and the RI was decreased compared with that before treatment(P<0.05).The increase of PSV,EDV,Vm,and PI of the MCA and the decrease of RI in the study group were significantly superior to those in control group 1 and control group 2(P<0.05).No statistically significant differences in PSV,EDV,Vm,PI,and RI of MCA were shown between control group 1 and control group 2 after treatment(P>0.05).(3)After treatment,the serum sCD40L,Lp-PLA2,and GA levels in the three groups were decreased compared with those before treatment(P<0.05),and the decrease in the study group was significantly superior to that in control group 1 and control group 2(P<0.05).However,the differences of the serum levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(4)After treatment,the serum levels of neurofactors of NSE,S100β,and MBP in the three groups were all decreased compared with those before treatment(P<0.05),and the decrease of the serum levels in the study group was significantly superior to that in control group 1 and control group 2,while the differences of the serum levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(5)After treatment,the vascular endothelial function indicators of serum vWF and ET-1 levels in the three groups were decreased compared with those before treatment(P<0.05),and the serum NO level was increased compared with that before treatment(P<0.05).The decrease of serum vWF and ET-1 levels and the increase of serum NO level in the study group were significantly superior to those in control group-1 and control group-2(P<0.05),while the difference of serum vWF,ET-1 and NO levels after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(6)After treatment,the NIHSS scores for neurological function in the three groups were decreased(P<0.05)and the MBI scores for ADL were increased(P<0.05)compared with those before treatment,and the decrease of the NIHSS scores and the increase of the MBI scores in the study group was significantly superior to those in control group 1 and control group 2(P<0.05),while and the differences of NIHSS and MBI scores after treatment between control group 1 and control group 2 were not statistically significant(P>0.05).(7)The incidence rate of adverse reactions was 15.38%(6/39)in the study group,7.69%(3/39)in the control group 1,and 12.82%(5/39)in the control group 2,and the pairwise comparison between groups showed that the difference was not statistically significant(P>0.05).Conclusion Zhi Long Huoxue Tongyu Capsules combined with Edaravone exert certain efficacy in the treatment of patients with ICVD of qi deficiency and blood stasis syndrome,and the combined therapy is effective on improving blood circulation,restoring neurological function,enhancing the ADL,with higher safety.Its therapeutic mechanism may be related to the improvement of the vascular endothelial function,and the down-regulation of serum levels of neurofactors of NSE,S100 β,MBP,and serum expression levels of sCD40L,Lp-PLA2,and GA.

Objective To explore the effect of Sanshen Shuxin Decoction combined with Huan-gqi Injection in the treatment of coronary heart disease(CHD)and its impacts on left ventricular function and Rho kinase(ROCK)expression.Methods A total of 120 CHD patients admitted to our hospital from August 2021 to August 2023 were selected as study subjects and randomly divided into three groups,with 40 patients in each group using a random number table method.All three groups received basic treatment.On this basis,control group 1 received Sanshen Shuxin Decoction,control group 2 received Huangqi Injection,and the combined group received both Sanshen Shuxin Decoction and Huangqi Injection.The treatment effects,occurrence of angina pectoris,hemorheo-logical parameters[fibrinogen(FIB),low-shear blood viscosity,erythrocyte aggregation index,high-shear blood viscosity],blood lipid indicators[total cholesterol(TG),triglycerides(TC),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C)],car-diac function[stroke volume(SV),cardiac output(CO),left ventricular ejection fraction(LVEF)],ROCK activity,and occurrence of adverse reactions were compared among the three groups.Results The total effective rate of treatment in the combined group was higher than that in control group 1 and control group 2(P＜0.05).After 14 days of treatment,the frequency of angina pectoris episodes decreased and the duration of episodes shortened in all three groups compared with before treatment,and the combined group had a lower frequency and shorter duration of angina pec-toris episodes than control group 1 and control group 2(P＜0.05).There were no statistically sig-nificant differences in the frequency and duration of angina pectoris episodes between control group 1 and control group 2 after 14 days of treatment(P＞0.05).After 14 days of treatment,FIB level,e-rythrocyte aggregation index,low-shear blood viscosity,and high-shear blood viscosity decreased in all three groups compared with before treatment,and the combined group had lower values than con-trol group 1 and control group 2(P＜0.05).There were no statistically significant differences in these hemorheological parameters between control group 1 and control group 2 after 14 days of treat-ment(P＞0.05).After 14 days of treatment,TG,TC,and LDL-C levels decreased in all three groups compared with before treatment,and the combined group had lower levels than control group 1 and control group 2.HDL-C levels increased in all three groups compared with before treatment,and the combined group had higher HDL-C level than control group 1 and control group 2(P＜0.05).There were no statistically significant differences in TG,TC,LDL-C,and HDL-C levels be-tween control group 1 and control group 2 after 14 days of treatment(P＞0.05).After 14 days of treatment,LVEF,CO,and SV increased in all three groups compared with before treatment,and the combined group had higher values than control group 1 and control group 2(P＜0.05).There were no statistically significant differences in LVEF,CO,and SV between control group 1 and con-trol group 2 after 14 days of treatment(P＞0.05).Before treatment,ROCK activity was(61.28±7.15)％in the combined group,(60.85±5.93)％in control group 1,and(60.61±6.27)％in control group 2,with no statistically significant difference among the three groups(P＞0.05).After 14 days of treatment,ROCK activity decreased in all three groups compared with before treatment,and the combined group had lower ROCK activity than control group 1 and control group 2(P＜0.05).ROCK activity was(40.18±5.03)％in the combined group,(48.24±6.29)％in con-trol group 1,and(47.79±6.12)％in control group 2 after 14 days of treatment.There was no sta-tistically significant difference in ROCK activity between control group 1 and control group 2 after 14 days of treatment(P＞0.05).There was no statistically significant difference in the incidence of adverse reactions among the three groups(P＞0.05).Conclusion Sanshen Shuxin Decoction combined with Huangqi Injection has a significant effect in the treatment of CHD patients.It can im-prove patients'prognosis and ensure treatment safety,demonstrating high clinical value.

Objective:To investigate the application value of cannulated screws in the treatment of Hauck type Ⅱ ulnar styloid process fracture.Methods:The clinical data of 93 patients with Hauck type Ⅱ ulnar styloid process fracture who received treatment at Fuzhou Second Hospital Affiliated to Xiamen University from December 2020 to February 2023 were retrospectively analyzed for a case-control study. Among these patients, 38 patients did not undergo surgical fixation and 55 patients underwent surgical fixation. Twenty-seven patients underwent surgical fixation with cannulated screws and twenty-eight patients underwent surgical fixation with Kirschner wires. The fracture healing, postoperative rehabilitation, and functional recovery of the wrist were compared among groups.Results:The fracture healing rate and the incidence of distal radioulnar joint instability in the surgical fixation group were 100.00% (55/55) and 5.45% (3/55), respectively. These were significantly higher and lower respectively compared with the non-surgical fixation group [57.89% (22/38), 50.00% (19/38), χ 2 = 27.66, 24.69, both P < 0.001]. The wrist function recovery in the surgical fixation group was significantly superior to that in the non-surgical fixation group ( Z = -5.18， P < 0.001). There were no statistically significant differences in operative time and intraoperative blood loss between the cannulated screw group and the Kirschner wire group [(21.41 ± 5.15) minutes vs. (20.93 ± 5.71) minutes, (2.11 ± 0.97) mL vs. (2.07 ± 0.90) mL, t = 0.32, 0.15, both P > 0.05]. The fracture healing time and rehabilitation intervention time in the cannulated screw group were shorter than those in the Kirschner wire group [(6.48 ± 1.05) weeks vs. (9.14 ± 1.24) weeks, (2.11 ± 0.32) weeks vs. (3.11 ± 0.57) weeks, t = 8.57, 7.98, both P < 0.001]. The postoperative wrist function scores in the cannulated screw group were superior to those in the Kirschner wire group ( Z = -2.21, P < 0.05). Conclusion:For patients with Hauck type Ⅱ ulnar styloid process fracture, surgical fixation can promote the recovery of wrist function after surgery, and cannulated screw fixation is an effective method for the treatment of Hauck type Ⅱ ulnar styloid process fracture.

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 investigate the knowledge, attitude and practice of general practitioners (GPs) in Shenzhen towards managing patients with common mental health problems.Methods:It was a cross-sectional study, from September 19 to October 31, 2020, 500 GPs from 100 community health centers (CHC) in 10 districts of Shenzhen municipality were randomly selected as the research subjects by stratified random sampling; the survey was conducted by self-filled questionnaire, which included general conditions, knowledge tests of common psychological problems (generalized anxiety disorder, depressive disorder, panic attacks, sleep disorders), GPs′ attitudes to take care of common psychological problems, and GPs′ practice of caring for common psychological problems.Results:A total of 500 questionnaires were distributed and 329 valid ones were collected. In terms of knowledge, GPs had the highest accuracy of answering the characteristics of depressive disorder (97.3%, 320/329), and the lowest accuracy of case analysis of panic attacks (50.2%, 165/329). In terms of attitude, 71.1%(234/329)of GPs agreed that "common psychological problems should be taken care of",there was a statistically significant difference in attitude scores among GPs with different years of working in CHC ( Z=14.60, P=0.006). In terms of practice, the most encountered mental health problem was insomnia (91.2%, 300/329), 46.5% (153/329) of GPs would use psychological assessment scales, 52.9% (174/329) of GPs would choose direct referral, and there were statistically significant differences in attitude scores among GPs with different years of working ( Z=10.70, P=0.030) and years of working in CHC ( Z=22.14, P<0.001). Conclusions:GPs have a positive attitude in taking care of common psychological problems, but lack of knowledge and confidence. As working in CHC for more years, GPs are more inclined to care for patients with common psychological problems in practice.

Objective:To explore the diversity and structural changes of intestinal flora in patients with sepsis.Methods:A total of 55 patients were enrolled who visited the Emergency Department of several Grade III-A hospitals from November 2015 to March 2016. Among them, 25 patients with sepsis metthe diagnostic criteria of Sepsis 3.0 and 30 patients had no sepsis. The intestinal flora from all fecal samples was sequenced by 16S rRNA sequencing technology. The diversity and structure changes of the flora were analyzed using Uparse, Qiime, R and LEfSe software.Results:There was no significant difference in sex, age, chronic underlying diseases, and the diversity of intestinal flora between the sepsis and non-sepsis groups (all P>0.05). The structure of intestinal flora was significant different between the two groups ( P<0.05). Abundances of Negativicutes, Selenomonadales, Veillonellaceae, Lachnospiraceae, Faecalibacterium, Hafnia, Lachnoclostridium, Blautia and Ruminococcus in intestinal flora from patients with sepsis were significantly reduced, but those of Bacilli, Coriobacteriia, Lactobacillales, Coriobacteriales, Clostridiaceae, Coriobacteriaceae, Clostridium_sensu_stricto, Collinsella and Collinsella_aerofaciens were significantly increased. Conclusions:There is no change in the diversity of intestinal flora between the sepsis and non-sepsis groups. There are structural changes of intestinal flora in patients with sepsis.
