BackgroundMigraine is a common chronic neurological disease， and patent foramen ovale （PFO） has been closely associated with migraine. Current research primarily focuses on the pathological mechanism and the therapeutic effects of interventional closure， with limited attention paid to the impact of PFO on sleep quality in migraine patients. ObjectiveTo compare the difference in sleep quality between PFO-positive and PFO-negative migraine patients， and to analyzes influencing factors of sleep quality in PFO-positive migraine patients， so as to provide references for clinical interventions to improve sleep quality in PFO-positive migraine patients. MethodsA total of 673 migraine patients who met the diagnostic criteria of migraine in the International Classification of Headache Disorders， third edition （ICHD-3）， and all patients underwent contrast-enhanced transcranial Doppler （c-TCD） and transthoracic echocardiographic right heart contrast echocardiography （cTTE） in the Third Hospital of Mianyang from January 2020 to October 2024. Basic demographic data were collected using a self-designed questionnaire， headache severity was assessed with the Visual Analogue Scale （VAS）， and sleep quality was invaluated using the Pittsburgh Sleep Quality Index （PSQI）. PFO patients was diagnosed through c-TCD combined with c-TTE. Binary logistic regression analysis was employed to examine the influencing factors of sleep quality in PFO-positive migraine patients. ResultsA total of 673 （100.00%） migraine patients were enrolled， including 223 PFO-positive cases （33.14%） and 450 PFO-negative cases（66.86%）. The PFO-positive group showed significantly more severe headache severity （χ²=15.799， P<0.01） and poorer sleep quality （χ²=14.377， P<0.01） compared with PFO-negative group. PFO-positive patients demonstrated significantly higher barrier factor scores of sleep quality， sleep latency， sleep efficiency， sleep disturbance， hypnotic medication use， and daytime dysfunction compared with PFO-negative counterparts （t=3.634， 3.269， 2.785， 3.428， 2.907， 3.637， Bonferroni adjust P<0.05/7=0.007）.By contrast， no significant difference was noted in sleep duration scores between the two groups（t=2.349， Bonferroni adjust P>0.05/7=0.007）.The Binary Logistic regression analysis revealed that age （OR=1.021， 95% CI： 1.001~1.041）， headache severity （OR=6.030， 95% CI： 4.085~8.901）， and PFO grade （OR=1.893，95% CI： 1.288~2.784）were significant influencing factors for sleep quality in migraine patients with PFO. ConclusionMigraine patients with PFO-positive exhibited poorer sleep quality compared wtih PFO-negative patients. Older age， higher headache servity， and more severe PFO grade are identified as risk factors for impaired sleep quality in PFO-positive migraine patients.

Cemental tear is a rare and indetectable condition unless obvious clinical signs present with the involvement of surrounding periodontal and periapical tissues. Due to its clinical manifestations similar to common dental issues, such as vertical root fracture, primary endodontic diseases, and periodontal diseases, as well as the low awareness of cemental tear for clinicians, misdiagnosis often occurs. The critical principle for cemental tear treatment is to remove torn fragments, and overlooking fragments leads to futile therapy, which could deteriorate the conditions of the affected teeth. Therefore, accurate diagnosis and subsequent appropriate interventions are vital for managing cemental tear. Novel diagnostic tools, including cone-beam computed tomography (CBCT), microscopes, and enamel matrix derivatives, have improved early detection and management, enhancing tooth retention. The implementation of standardized diagnostic criteria and treatment protocols, combined with improved clinical awareness among dental professionals, serves to mitigate risks of diagnostic errors and suboptimal therapeutic interventions. This expert consensus reviewed the epidemiology, pathogenesis, potential predisposing factors, clinical manifestations, diagnosis, differential diagnosis, treatment, and prognosis of cemental tear, aiming to provide a clinical guideline and facilitate clinicians to have a better understanding of cemental tear.

Objective To understand the genetic basis of the adaptation of Culex tritaeniorhynchus to different environmental ecology in Jining City, Shandong Province, so as to provide insights into understanding of the population structure or isolation pattern of Cx. tritaeniorhynchus in the city. Methods Seven sampling sites were selected from urban, suburban and rural areas of Jining City, Shandong Province from June to August 2023, and mosquitoes were collected using mosquito-trapping lamps. All collected adult mosquitoes were identified morphologically. Genomic DNA was extracted from a single female Cx. tritaeniorhynchus mosquito, and the mitochondrial cytochrome C oxidase I (COI) gene was amplified using a PCR assay, sequenced and subjected to molecular identification. The number of haplotypes, haplotype diversity (Hd), nucleotide diversity (Pi), and average number of nucleotide differences (K) of Cx. tritaeniorhynchus DNA sequences were estimated among different sampling sites using the software DnaSP 6, and a neutrality test was performed. The fixation index (F_ST), and gene flow (number of migrants, Nm) of Cx. tritaeniorhynchus populations were calculated using the software Arlequin 3.5.2, and subjected to analysis of molecular variance (AMOVA). In addition, a haplotype network diagrams and a phylogenetic tree of Cx. tritaeniorhynchus populations were created using the software PopART and MEGA 11, respectively. Results A total of 420 sequences were successfully amplified from the COI gene of Cx. tritaeniorhynchus samples collected from 7 sampling sites in Jining City, and a gene fragment sequence with a length of 603 bp was obtained, with 55 variable sites and 46 haplotypes and without insertion or deletion mutations. Of the 46 haplotypes, H01 was the dominant shared haplotype, and the haplotype frequency increased gradually from urban areas (34.00%) to rural areas (47.00%). The mean Hd, Pi and K values of Cx. tritaeniorhynchus COI genes were 0.814, 0.024 and 14.129, 0.489, 0.016 and 7.941 and 0.641, 0.016 and 10.393 in suburban, urban, and rural areas, respectively, with the highest population diversity of Cx. tritaeniorhynchus in suburban areas and the lowest in urban areas. Paired F_ST analysis among different types of sampling sites showed that the mean F_ST value was 0.029 between urban and suburban areas, indicating more frequent inter-population communication. AMOVA revealed that the percentage of intra-population variation (95.74%) was higher than that of inter-population variation (4.26%). Neutrality tests showed deviation from neutrality in Cx. tritaeniorhynchus populations collected from Nanyang Township (Tajima’s D = 2.793, Fu’s Fs = 6.429, both P values < 0.05). In addition, the mismatch distribution curves of Cx. tritaeniorhynchus COI gene appeared bimodal or multimodal patterns in Jining City, indicating a relatively stable overall population size. Conclusions The mitochondrial COI gene may be used as a molecular marker to investigate the population genetic diversity of Cx. tritaeniorhynchus. The population genetic diversity of Cx. tritaeniorhynchus is higher in the suburban areas of Jining City than in rural and urban areas, and there are frequent genetic exchanges between Cx. tritaeniorhynchus populations from urban and suburban areas.

ObjectiveTo identify the rate， population characteristics， and vaccination history of repeat infections among previously infected people in the current epidemic based on the rate of repeat infection and population characteristics of different mutant strains at different times in Pudong New Area of Shanghai， and to provide reference for the prevention and control strategies of novel coronavirus repeat infections. MethodsA total of 9 250 investigated subjects were randomly selected from the new cases of asymptomatic infection and confirmed cases reported by Pudong New Area from March to May 2022. The investigation mainly focused on demographic characteristics， nucleic acid or antigen test results， and symptoms after infection. The repeat infection rates among different populations were compared， and logistic regression was used to analyze the impact of gender， age， and vaccination status on repeat infections. ResultsThe survey sample of 9 250 people had a response rate of 81.85%. There were 4 043 males （53.40%） and 3 528 females （46.60%）， with a median age of 34 years old （P₂₅， P₇₅： 7， 61）. The overall vaccine uptake rate was 59.44% （4 500/7 571）. In December of 2022， there were 563 cases of repeat infection， with an infection rate of 7.44%. The lowest rate of repeat infection was seen in the 3‒ year-old group （2.86%） and the highest rate in the 30‒ year-old group （12.42%）， with significant differences between different age groups. The repeated infection rate for those who had completed their vaccinations was significantly lower （6.57%） compared to those who had not （7.11%）. The age groups of 3‒ years， 70‒79 years， as well as individuals who completed full vaccination and received booster shots were protective factors against repeat infections. ConclusionThe overall rate of reinfection among the infected in Shanghai during the spring of 2022 was low in the outbreak of the Omicron variant， and the rate of reinfection in the 3‒ year-old group was significantly lower than in other age groups. Completing the full course of vaccination significantly reduces the risk of reinfection. Although the reinfection rate is high in individuals who received booster shots， it remains a mitigating factor compared to those who do not receive the vaccine. It is recommended to continue monitoring reinfections in key populations and further strengthen immunization efforts.

ObjectiveTo analyze the epidemiological characteristics and etiology of clustered outbreaks of hand， foot， and mouth disease （HFMD） in Pudong New Area， Shanghai from 2017 to 2022， and to provide a scientific basis for the prevention and control of HFMD in the area. MethodsThe data related to HFMD clustered outbreaks from 2017 to 2022 were obtained from the Pudong New Area HFMD outbreak database. Descriptive analysis was conducted to explore the outbreak scope， seasonal characteristics， distribution of occurrence settings， and etiological composition. ResultsFrom 2017 to 2022， Pudong New Area reported a total of 2 547 HFMD clusters， involving 8 884 cases， with an average of 3.49 cases per event. The majority of events （78.52%） had between 2 and 4 cases. The peak reporting periods for clustered HFMD from 2017 to 2019 and in 2021 were during the summer （May‒July） and autumn （September‒November）. The seasonal pattern was less distinct in 2020 and 2022， likely due to the impact of the COVID-19 pandemic. The majority of clustered outbreaks occurred in childcare facilities （44.64%）， followed by households/neighborhood committees （44.21%）， with schools accounting for a smaller proportion （12.39%）. The etiology revealed the coexistence of multiple enterovirus genotypes， with a positive detection rate of 60.46%， and CoxA6 being the dominant strain. ConclusionHFMD clustered outbreaks in Pudong New Area show fluctuating trends， with significant yearly differences in the number of incidents. The predominant seasons for outbreaks are summer and autumn， with CoxA6 identified as the dominant strain. The implementation of prevention and control measures for COVID-19 significantly reduced the occurrence of HFMD outbreaks. Continuous monitoring and focus on large-scale clustered outbreaks in key institutions are essential for the future.

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 analyze the expression of CREM in gastric cancer(GC)and its correlation with prognosis of the patients.Methods TCGA and GEO databases were used to analyze the expression levels of CREM mRNA in GC and adjacent tissues.Immunohistochemistry was used to examine the expression of CREM protein in 43 pairs of GC and adjacent tissues,and the correlation of CREM expression with clinicopathological features of the patients was analyzed.Kaplan-Meier survival analysis was used to explore the relationship between CREM expression and survival of GC patients.LinkedOmics database was used to annotate the GO function and KEGG pathway enrichment of CREM-related genes.Results Database analysis showed that CREM was highly expressed in GC tissues(P<0.05)and positively correlated with poor prognosis in GC patients(P=0.01).Immunohistochemistry results showed significantly higher CREM expression in GC tissues than in paired adjacent tissues(P<0.0001),and its expression level was correlated with T-stage and N-stage of the tumor(P<0.05).The overall survival of GC patients with high expression of CREM was shorter(RR=4.02,P=0.0046).Gene enrichment analysis showed that high CREM expression promotes occurrence and progression of GC very likely through the cell adhesion signaling pathway.Conclusion CREM is highly expressed in GC,and its high expression is associated with a poor prognosis of GC patients,suggesting the potential of CREM to serve as a prognostic indicator for GC.
