Objective:To investigate the effects of preoperative ticagrelor application on postoperative NF-κB signa-ling pathway,platelet aggregation and myocardial microcirculatory perfusion in patients with acute myocardial in-farction(AMI)and multivessel lesions undergoing percutaneous coronary intervention(PCI).Methods:A total of 120 AMI patients with multivessel lesions treated in our hospital were selected,randomly and equally divided into clopidogrel group and ticagrelor group.Corresponding drugs were given in each group before and after PCI.NF-κB signaling pathway related indexes,platelet aggregation rate,myocardial microcirculatory indexes before and af-ter medication,and incidence of major adverse cardio-and cerebrovascular events(MACCE)were observed and compared between two groups.Results:On 7d after PCI,compared with clopidogrel group,there were significant reductions in corrected TIMI frame count(CTFC)of left anterior descending(LAD)[(23.83±2.69)vs.(20.48± 3.05)],left circumflex(LCX)[(20.93±2.82)vs.(18.35±2.37)]and right coronary artery(RCA)[(23.68± 3.15)vs.(21.13±2.79)]in ticagrelor group,P=0.001 all;compared with clopidogrel group after 30d treatment,there were significant reductions in platelet maximum aggregation rate,maximum depression amplitude of ST seg-ment,ST segment depression time,24h ischemia onset times,levels of Toll-like receptor 4(TLR4)protein,NF-κB protein,tumor necrosis factor(TNF)-a and interleukin(IL)-6 in ticagrelor group,P=0.001 all.There was no significant difference in incidence rate of MACE between two group within six months,P=0.186.Conclu-sion:Ticagrelor can improve myocardial microcirculation,inhibit platelet aggregation,and reduce inflammatory re-sponse in AMI patients with multivessel lesions,and the mechanism may be related to the inhibition of NF-κB sig-naling pathway activity by ticagrelor.

Objective:To compare clinical characteristics,treatment patterns and physiological indicators in bipolar disorder(BD)patients with different age of onset.Methods:Totally 380 patients with DSM-5 BD were se-lected in this study.Psychiatrists diagnosed the patients using the Mini International Neuropsychiatric Interview.The clinical information questionnaire and the Global Assessment of Functioning scale were utilized to collected clinical characteristics,treatment status,and physiological indicators.The onset age of BD was divided into 21 and 35 years as cut-off points.Multivariate logistic regression and linear regression were used to analyze related factors.Results:Among the 380 patients with BD,199 cases were early-onset group(52.4％),121 cases were middle-onset group(31.8％),and 60 cases were late-onset group(15.8％).There were 26.6％of patients in the early-onset group in-itially diagnosed as depression,23.1％in the middle-onset group,and 11.7％in the late-onset group.Multivariate analysis revealed that compared to the early-onset group of BD,the middle-onset(OR=2.22)and late-onset(OR=4.99)groups had more risk to experience depressive episodes,and the late-onset group(OR=6.74)had 6.74 times of risk to suffer from bipolar Ⅱ disorder.Additionally,patients in the middle-onset(β=-1.52)and late-on-set(β=-4.29)groups had shorter durations of delayed treatment,and those in the middle-onset(β=-1.62)and late-onset(β=-3.14)groups had fewer hospitalizations.Uric acid levels were lower in both the middle-onset(β=-28.39)and late-onset(β=-31.47)groups,and total cholesterol level was lower in the middle-onset group(β=-0.23).Conclusion:Patients with BD in different age of onset show significant differences in clinical charac-teristics,treatment conditions and physiological indicators.

Mitral valve prolapse is one of the common causes of mitral regurgitation.Mitral valve prolapse complicated with leaflet cleft is rare in clinical practice,which most often undergo surgical mitral valve repair or mitral valve replacement.We report a case of mitral valve prolapse with posterior leaflet cleft treated by transcatheter edge-to-edge mitral valve repair,in order to provide a model for similar cases.

OBJECTIVE: This study was aimed at investigating the carrier rate of, and molecular variation in, α- and β-globin gene mutations in Hunan Province. METHODS: We recruited 25,946 individuals attending premarital screening from 42 districts and counties in all 14 cities of Hunan Province. Hematological screening was performed, and molecular parameters were assessed. RESULTS: The overall carrier rate of thalassemia was 7.1%, including 4.83% for α-thalassemia, 2.15% for β-thalassemia, and 0.12% for both α- and β-thalassemia. The highest carrier rate of thalassemia was in Yongzhou (14.57%). The most abundant genotype of α-thalassemia and β-thalassemia was -α ^3.7/αα (50.23%) and β ^IVS-II-654/β ^N (28.23%), respectively. Four α-globin mutations [CD108 (ACC>AAC), CAP +29 (G>C), Hb Agrinio and Hb Cervantes] and six β-globin mutations [CAP +8 (C>T), IVS-II-848 (C>T), -56 (G>C), beta nt-77 (G>C), codon 20/21 (-TGGA) and Hb Knossos] had not previously been identified in China. Furthermore, this study provides the first report of the carrier rates of abnormal hemoglobin variants and α-globin triplication in Hunan Province, which were 0.49% and 1.99%, respectively. CONCLUSION Our study demonstrates the high complexity and diversity of thalassemia gene mutations in the Hunan population. The results should facilitate genetic counselling and the prevention of severe thalassemia in this region.

OBJECTIVE: This work explores the impact of electroacupuncture (EA) on acute postoperative pain (APP) and the role of stimulator of interferon genes/type-1 interferon (STING/IFN-1) signaling pathway modulation in the analgesic effect of EA in APP rats. METHODS: The APP rat model was initiated through abdominal surgery and the animals received two 30 min sessions of EA at bilateral ST36 (Zusanli) and SP6 (Sanyinjiao) acupoints. Mechanical, thermal and cold sensitivity tests were performed to measure the pain threshold, and electroencephalograms were recorded in the primary somatosensory cortex to identify the effects of EA treatment on APP. Western blotting and immunofluorescence were used to examine the expression and distribution of proteins in the STING/IFN-1 pathway as well as neuroinflammation. A STING inhibitor (C-176) was administered intrathecally to verify its role in EA. RESULTS: APP rats displayed mechanical and thermal hypersensitivities compared to the control group (P < 0.05). APP significantly reduced the amplitude of θ, α and γ oscillations compared to their baseline values (P < 0.05). Interestingly, expression levels of proteins in the STING/IFN-1 pathway were downregulated after inducing APP (P < 0.05). Further, APP increased pro-inflammatory factors, including interleukin-6, tumor necrosis factor-α and inducible nitric oxide synthase, and downregulated anti-inflammatory factors, including interleukin-10 and arginase-1 (P < 0.05). EA effectively attenuated APP-induced painful hypersensitivities (P < 0.05) and restored the θ, α and γ power in APP rats (P < 0.05). Meanwhile, EA distinctly activated the STING/IFN-1 pathway and mitigated the neuroinflammatory response (P < 0.05). Furthermore, STING/IFN-1 was predominantly expressed in isolectin-B4- or calcitonin-gene-related-peptide-labeled dorsal root ganglion neurons and superficial laminae of the spinal dorsal horn. Inhibition of the STING/IFN-1 pathway by intrathecal injection of C-176 weakened the analgesic and anti-inflammatory effects of EA on APP (P < 0.05). CONCLUSION EA can generate robust analgesic and anti-inflammatory effects on APP, and these effects may be linked to activating the STING/IFN-1 pathway, suggesting that STING/IFN-1 may be a target for relieving APP.

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.

AIM:To explore the effect of microRNA-184(miR-184)on compensatory lung growth(CLG)af-ter lobectomy in multiple primary lung cancer(MPLC)and its mechanism.METHODS:(1)Lung tissue samples(n= 16)from MPLC patients and patients with good recovery after lobectomy(CLG)were collected,and the expression of miR-184 was measured by RT-qPCR.(2)Human alveolar epithelial cells were divided into NC-mimic group,miR-184 mimic group,OE-NC group,tissue inhibitor of metalloproteinase-2(TIMP-2)overexpression(OE-TIMP-2)group,and miR-184 mimic+OE-TIMP-2 group according to the transfection(n=3).The expression of miR-184,TIMP-2 mRNA and matrix metalloproteinase-14(MMP-14)mRNA was measured by RT-qPCR,and the protein expression of TIMP-2 and MMP-14 was determined by Western blot.The proliferation of the cells was measured by CCK-8 and colony formation assays.(3)C57BL/6J mice were divided into pneumonectomy(PNX)group and PNX+miR-184 mimic group(n=5).The flexiVent system was used to measure the vital capacity and lung compliance of the mice.Lung volume was measured by water dis-placement method,and lung tissue changes were observed by HE staining.RESULTS:The expression of miR-184 was significantly higher in the patients with better recovery after lobectomy(P＜0.01).Overexpression of miR-184 promoted the proliferation of human alveolar epithelial cells and the recovery of lung function in mice after PNX.In terms of mecha-nism,miR-184 showed targeted binding with TIMP-2,and overexpression of miR-184 promoted the expression of MMP-14 by inhibiting TIMP-2,thereby promoting the proliferation of human alveolar epithelial cells and the recovery of mouse lung function after PNX.CONCLUSION:miR-184 promotes CLG after PNX through the TIMP-2/MMP-14 axis.

OBJECTIVE: To establish a sensitive, simple and rapid detection method for African swine fever virus (ASFV) B646L gene. METHODS: A recombinase-aided amplification-lateral flow dipstick (RAA-LFD) assay was developed in this study. Recombinase-aided amplification (RAA) is used to amplify template DNA, and lateral flow dipstick (LFD) is used to interpret the results after the amplification is completed. The lower limits of detection and specificity of the RAA assay were verified using recombinant plasmid and pathogenic nucleic acid. In addition, 30 clinical samples were tested to evaluate the performance of the RAA assay. RESULTS: The RAA-LFD assay was completed within 15 min at 37 °C, including 10 min for nucleic acid amplification and 5 minutes for LFD reading results. The detection limit of this assay was found to be 200 copies per reaction. And there was no cross-reactivity with other swine viruses. CONCLUSION A highly sensitive, specific, and simple RAA-LFD method was developed for the rapid detection of the ASFV.

The COVID-19 pandemic is still ongoing in the world, the risk of COVID-19 spread from other countries or in the country will exist for a long term in China. In the routine prevention and control phase, a number of local COVID-19 epidemics have occurred in China, most COVID-19 cases were sporadic ones, but a few case clusters or outbreaks were reported. Winter and spring were the seasons with high incidences of the epidemics; border and port cities had higher risk for outbreaks. Active surveillance in key populations was an effective way for the early detection of the epidemics. Through a series of comprehensive prevention and control measures, including mass nucleic acid screening, close contact tracing and isolation, classified management of areas and groups at risk, wider social distancing and strict travel management, the local COVID-19 epidemics have been quickly and effectively controlled. The experiences obtained in the control of the local epidemics would benefit the routine prevention and control of COVID-19 in China. The occurrence of a series of COVID-19 case clusters or outbreaks has revealed the weakness or deficiencies in the COVID-19 prevention and control in China, so this paper suggests some measures for the improvement of the future prevention and control of COVID-19.
