ObjectiveTo observe the effects of electroacupuncture with "tonifying the kidney and dispelling stasis" acupoint prescription on sexual function in diabetic erectile dysfunction （DMED）model rats， and to explore its possible mechanism of action. MethodsSPF male SD rats were randomly divided into 10 each in blank group， model group， Tadalafil group， and electroacupuncture group. DMED rat model was prepared by high glucose and high fat diet combined with intraperitoneal injection of streptozotocin. After successful modelling， rats in the electroacupuncture group were given electroacupuncture intervention of "tonifying the kidney and dispelling stasis" acupoint prescription once every other day； Tadalafil group was given Tadalafil solution 0.5 mg/kg·d by gavage， and the blank group， model group and electroacupuncture group were given 10 ml/kg pure water by gavage once a day. Each group was intervened for 30 days. The body mass and blood glucose level of the rats were detected on the 1st， 8th， 15th， 22nd days and at the end of the intervention， respectively. At the end of the intervention， the penile erection of the rats was observed by using the apomorphine test； the level of plasma endothelial cell microparticles （EMPs）was detected by flow cytometry； the histopathological morphology of the penile cavernous body was observed by HE staining， and the pathological morphology of the endothelial cells of the penile vasculature was observed by electron microscopy. Serum sex hormones including testosterone （T）， follicle stimulating hormone （FSH）， luteinising hormone （LH） and vascular endothelial function-related factors including vascular endothelial growth factor （VEGF）， endothelin-1 （ET-1）， lectin-like oxidized low-density lipoprotein receptor-1 （LOX-1）， soluble E-selectin （sE-selectin）， and soluble intercellular adhesion molecule-1 （sICAM-1） were measured by ELISA method. ResultsCompared with blank group， the model group， Tadalafil group， and electroacupuncture group all had lower body mass and higher blood glucose levels at each time of testing （P＜0.01）. Compared with the blank group， the number of penile erections reduced in the model group， the level of CD31⁺ EMPs increased， the levels of serum T， FSH， LH， and VEGF reduced， and the levels of serum ET-1， LOX-1， sE-selectin， and sICAM-1 increased （P＜0.01）. Compared with the model group， the Tadalafil group and the electroacupuncture group showed an increased number of penile erections decreased level of CD31⁺ EMPs， increased levels of serum T， FSH， LH， and VEGF， and decreased levels of serum ET-1， LOX-1， sE-selectin， and sICAM-1 （P＜0.01）. Compared with the Tadalafil group， serum T， FSH， LH， VEGF levels increased and ET-1， LOX-1 levels decreased in the electroacupuncture group （P＜0.05 or P＜0.01）. HE staining and electron microscopic observation revealed that there was severe pathological damage to the cavernous tissue of the penis and vascular endothelial cells of the rat in the model group， which was ameliorated to a certain degree in both Tadalafil group and electroacupuncture group. ConclusionThe electroacupuncture prescription of "tonifying the kidney and dispelling stasis" can improve the erectile dysfunction of DMED rats， which is comparable to the effect of Tadalafi. Its mechanism of action may be related to the regulation of vascular endothelial function.

Objective:To investigate the efficacy and safety of tocilizumab in the treatment of critically ill children with acute necrotizing encephalopathy (ANE).Methods:It is a retrospective cohort study. The children with ANE admitted to the pediatric intensive care unit of 4 Chinese tertiary hospitals from December 2022 to November 2023 were divided into conventional treatment group and tocilizumab group, and the comparison between groups was performed by using Mann ‐ Whitney U test or Chi-square test. Results:Among 21 cases of severe ANE, there were 11 males with the onset age of 65 (27, 113) months. The duration from onset to PICU admission was 2 (1, 2) days. There were 13 cases of ultra-high fever (greater than 40 ℃), including 18 cases of convulsions, and 19 cases with a GCS score of less than 8 points. The causative agent was novel coronavirus Omicron in 7 cases and influenza A in 14 cases. All cases had central respiratory failure requiring mechanical ventilation. Of the 21 cases, 18 were shock, 15 were coagulopathy, 10 were kidney injury and 13 were liver dysfunction. Of these hospitalized patients, 8 children with ANE were treated with tocilizumab. Eight cases received continuous blood purification (CBP) treatment, 5 of them were combined with plasmapheresis. Serum cytokine levels were elevated in 21 children with ANE, including (interleukin, IL)-6 and IL-8 (61 (22, 1 513) and 68 (5, 296) ng/L). There were 14 cases (67%) deaths, including 11 cases in the conventional treatment group and 3 cases in the tocilizumab group. There was no significant difference in the mortality rate between the two groups ( P=0.056). Tocilizumab-related rash or other adverse events were not observed. Conclusions:The motality of critically ill ANE patients was high. The combination of Tocilizumab with conventional treatment did not reduce the motality of severe ANE patients, and no adverse reactions of tocilizumab were observed.

Background::While type 2 diabetes mellitus (T2DM) is considered a putative causal risk factor for coronary artery disease (CAD), the intrinsic link underlying T2DM and CAD is not fully understood. We aimed to highlight the importance of integrated care targeting both diseases by investigating the phenotypic and genetic relationships between T2DM and CAD.Methods::We evaluated phenotypic associations using data from the United Kingdom Biobank ( N = 472,050). We investigated genetic relationships by leveraging genomic data conducted in European ancestry for T2DM, with and without adjustment for body mass index (BMI) (T2DM: Ncase/ Ncontrol = 74,124/824,006; T2DM adjusted for BMI [T2DM adjBMI]: Ncase/ Ncontrol = 50,409/523,897) and for CAD ( Ncase/ Ncontrol = 181,522/984,168). We performed additional analyses using genomic data conducted in multiancestry individuals for T2DM ( Ncase/ Ncontrol = 180,834/1,159,055). Results::Observational analysis suggested a bidirectional relationship between T2DM and CAD (T2DM→CAD: hazard ratio [HR] = 2.12, 95% confidence interval [CI]: 2.01–2.24; CAD→T2DM: HR = 1.72, 95% CI: 1.63–1.81). A positive overall genetic correlation between T2DM and CAD was observed ( rg = 0.39, P = 1.43 × 10 -75), which was largely independent of BMI (T2DM adjBMI–CAD: rg = 0.31, P = 1.20 × 10 –36). This was corroborated by six local signals, among which 9p21.3 showed the strongest genetic correlation. Cross-trait meta-analysis replicated 101 previously reported loci and discovered six novel pleiotropic loci. Mendelian randomization analysis supported a bidirectional causal relationship (T2DM→CAD: odds ratio [OR] = 1.13, 95% CI: 1.11-1.16; CAD→T2DM: OR = 1.12, 95% CI: 1.07-1.18), which was confirmed in multiancestry individuals (T2DM→CAD: OR = 1.13, 95% CI: 1.10-1.16; CAD→T2DM: OR = 1.08, 95% CI: 1.04-1.13). This bidirectional relationship was significantly mediated by systolic blood pressure and intake of 3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors, with mediation proportions of 54.1% (95% CI: 24.9-83.4%) and 90.4% (95% CI: 29.3-151.5%), respectively. Conclusion::Our observational and genetic analyses demonstrated an intrinsic bidirectional relationship between T2DM and CAD and clarified the biological mechanisms underlying this relationship.

Objective:To study the role of special microbial communities in the development of periodontitis in type 2 diabetes melli-tus(T2DM)patients.Methods:40 subjects aged 20-70 years were included and divided into 3 groups:moderate to severe periodon-titis with T2DM(SP.T2DM,n=15),moderate to severe periodontitis group(SP,n=15)and normal healthy group(N,n=10).The basic information,periodontal clinical indicators and blood sugar of the subjects were recorded.Subgingival plaque samples were col-lected,DNA samples of the plaque were extracted,and sequenced by Illumina NovaSeq6000 platform.The microbial diversity,eco-logical characteristics and functions of the plaque were analyzed by Uparse,SPSS and other softwares.Results:481 species in 22 phyla,30 classes,73 orders,129 families and 265 genera were obtained from the samples.Beta polymorphism analysis showed that the species composition of CP.T2DM group and CP group was similar.Alpha polymorphism analysis showed that the species richness and evenness in CP.T2DM group and CP group were higher than those in N group(P＜0.01).Venn diagram analysis showed that the species richness of the plaque in CP.T2DM group was the highest,followed by CP group and the lowest in N group.At the genus lev-el,Klebsiella and Bifidobacterium in CP.T2DM group were larger than those in CP group and N group(P＜0.05),and between group CP and N,P＞0.05.At the species level,the Capnocytophaga leadbetteri in CP.T2DM group was higher than that in CP group and N group(P＜0.05),between group CP and N,P＞0.05;There were some differences in the microbial community structure of subgingival plaque among the 3 groups.The species richness of subgingival flora in patients with CP and T2DM was higher than that in patients with CP and healthy people.Conclusion:The increase of Klebsiella,Bifidobacterium and Capnocytophaga leadbetter in subgingival flora of patients with moderate and severe periodontitis may be related to the development of T2DM.

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.

Abstract: Objective To analyze the causes of foodborne illness outbreaks in Inner Mongolia, so as to provide reference for understanding systemic risks and formulating prevention and control measures. Methods Data on foodborne disease outbreaks in Inner Mongolia Autonomous Region from 2016 to 2021 were collected through the "Foodborne Disease Outbreak Monitoring System" for attribution analysis. Results A total of 591 outbreak events were included from 2016 to 2021. Single -dimensional attribution analysis showed that the main causes of foodborne disease outbreaks in this region were vegetables and vegetable products, and meat and meat products, respectively accounting for 20.5% (121/591) and 12.6% (75/591) of the total events. leading contributing factor was improper processing, accounting for 16.2%(96/591), and the main pathogenic factor was toxic plants and their toxins, accounting for 14.9%(88/591). Multi-dimensional attribution analysis showed that the highest number of outbreak events occurred in summer, with 290 cases accounting for 49.1% (290/591) of the total number of events. The eastern, central, and western regions also had the highest number of events in summer, accounting for 53.6% (180/336), 39.5% (60/152), and 48.5% (50/103) of the total number of events in this region, respectively. Among vegetables and vegetable products, improper processing led to the majority of outbreaks caused by toxic plants and their toxins, accounting for 58.7% (71/121) of total events. For meat and meat products, improper storage resulting in the most outbreaks of biological pollution, accounting for 16.0%(12/75) of the total number of meat and meat product incidents. Majorities of death cases were primarily due to accidental ingestion or misuse of non-food items (such as poisonous mushrooms), comprising 38.5% (5/13) of total deaths. Conclusions The main food, triggering factors, and pathogenic factors involved in the outbreak of foodborne diseases in this region are relatively routine and controllable. Therefore, efforts should be made to strengthen public food safety education to reduce the occurrence of foodborne diseases.

Bronchial asthma is the most common chronic disease in childhood.In clinical diagnosis and treatment, it is found that some children with asthma often have neuropsychiatric disorders of different severity, such as autism spectrum disorders, attention deficit-hyperactivity disorders, panic disorders and anxiety, which render the prognosis and treatment of asthma difficult.Some reports suggest that the " lung-brain axis" of bronchial asthma is related to the outbreak of inflammation-related mechanisms.A new idea to improve bronchial asthma with neuropsychiatric diseases may be inhibiting the release of inflammatory factors and blocking lung-brain inflammation communication.As one of the more thoroughly studied inflammasome family members, NOD-like receptor pyrin domain-containing protein 3 (NLRP3) is widely involved in the mechanisms of neuroinflammation and bronchial asthma attacks.In this article, the role of NLRP3 in the " lung-brain axis" immune inflammation mechanism of bronchial asthma is reported, which may provide new ideas for the diagnosis, treatment and research of bronchial asthma and neuropsychiatric comorbidities.

Objective:To investigate the effect and mechanism of 6-formylindolo[3,2-b]carbazole (FICZ) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice.Methods:Male C57BL/6J mice aged 8-12 weeks were divided into 4 groups with 8 mice in each group, according to the method of simple random sampling. Sepsis-induced ALI mice model was established by intraperitoneal injection of LPS 5 mg/kg (LPS group), and phosphate buffer saline (PBS) control group (PBS group) was injected with equal volume of PBS. The LPS+FICZ group was intervened by intraperitoneal injection of 1 μg FICZ 1 hour after LPS stimuli, while the FICZ control group (FICZ group) was given the same amount of FICZ 1 hour after intraperitoneal injection of PBS. Serum and lung tissue were collected 24 hours after LPS stimuli, and the pathological changes of lung tissue were analyzed by hematoxylin-eosin (HE) staining and wet/dry weight (W/D) ratio of lung tissue. The concentrations of inflammatory factors in serum and lung tissue were detected by enzyme linked immunosorbent assay (ELISA). The expression levels of endoplasmic reticulum stress signaling pathway related molecules were detected by real-time fluorescent quantitative polymerase chain reaction (RT-qPCR) and Western blotting.Results:Compared with PBS group, inflammatory cell infiltration, alveolar collapse and obvious alveolar exudative lesions had increased, lung tissue W/D ratio was significantly increased, serum interleukin-6 (IL-6) level, lung tissue IL-6 mRNA expression, and the mRNA expressions of glucose-regulated protein 78 (GRP78), protein kinase R-like endoplasmic reticulum kinase (PERK), CCAAT/EBP homologous protein (CHOP), and the protein expressions of GRP78, PERK, activating transcription factor 6 (ATF6), CHOP in lung tissue were significantly increased in LPS group. However, the indexes of FICZ group were not affected. Compared with LPS group, LPS+FICZ group had less inflammatory cell infiltration, relatively intact alveolar structure. Lung W/D weight ratio in LPS+FICZ group was significantly decreased (5.38±0.10 vs. 6.60±0.30, P < 0.01), so as serum IL-6 (ng/L: 15.55±3.77 vs. 32.22±3.84) and lung IL-6 mRNA expression (2 -ΔΔCt: 0.79±0.21 vs. 6.89±0.92, both P < 0.01). The mRNA expressions of GRP78, PERK and CHOP were also significantly decreased [GRP78 mRNA (2 -ΔΔCt): 1.90±0.16 vs. 7.55±1.29, PERK mRNA (2 -ΔΔCt): 1.68±0.20 vs. 4.54±0.89, CHOP mRNA (2 -ΔΔCt): 1.13±0.24 vs. 4.44±1.13, all P < 0.05], and the protein expressions of GRP78, PERK, ATF6 and CHOP were significantly decreased (GRP78/GAPDH: 0.59±0.02 vs. 0.77±0.01, PERK/GAPDH: 0.48±0.03 vs. 1.04±0.05, ATF6/GAPDH: 0.51±0.03 vs. 0.65±0.01, CHOP/GAPDH: 0.91±0.05 vs. 1.11±0.07, all P < 0.05). Conclusion:FICZ protects LPS-induced ALI possibly via suppressing endoplasmic reticulum stress and reducing IL-6 expression in blood and lung tissue.

Objective:To analyze the risk factors of deep venous thrombosis (DVT) in patients with tibial plateau fracture during preoperative period.Methods:From July 2017 to October 2019, a total of 264 patients undergoing surgeries of tibial plateau fractures were enrolled. Duplex ultrasonography (DUS) during hospitalization was used to screen for DVT of the bilateral lower extremities. Patients were divided into DVT group and non-DVT group according to results of DUS. Data on demographics, comorbidities, injury-related data, fracture type, laboratory biomarkers were collected and compared between groups with and without DVT.Results:The incidence of preoperative DVT was 39.0% (103/264) among 264 patients with traumatic tibial plateau fractures, and distal thrombosis predominated in DVT group. There were 103 cases in DVT group. 55 were males and 48 were females. The average age was 54.00±11.12. According to the Schatzker classification of tibial plateau fractures, 7 cases belonged to type I, 37 to type II, 2 to type III, 11 to type IV, 29 to type V, and 17 to type VI. There were 161 cases in non-DVT group. 89 were males and 72 were females. The average age was 48.57±13.25. According to the Schatzker classification of tibial plateau fractures, 23 cases belonged to type I, 76 to type II, 2 to type III, 10 to type IV, 33 to type V, and 17 to type VI. Univariate analysis showed that age ( t=3.451, P=0.001), the type of tibial plateau fracture ( χ2=8.314, P=0.004), D-dimer ( χ2=18.552, P<0.001), APTT ( t=2.869, P=0.004), ALB ( t=2.292, P=0.023) and Hb ( t=1.983, P=0.048) were statistically different than those in non-DVT group. Multivariate analysis showed age ( OR=1.033, 95% CI: 1.009, 1.058; P=0.007), the type of tibial plateau fracture ( OR=1.829, 95% CI: 1.014, 3.299; P=0.045) and D-dimer ( OR=1.914, 95% CI: 1.057, 3.464; P=0.032) were independent risk factors. Conclusion:The incidence of DVT in patients with tibial plateau fractures during preoperative period is high, and distal thrombosis is the main part of venous thrombosis of lower extremity. The type of tibial plateau fracture, age and the level of D-dimer are independent risk factors of preoperative DVT in patients with tibial plateau fractures.
