Objective To compare the diagnostic performance of two syphilis reverse testing protocols recommended by the U.S.Centers for Disease Control and Prevention(USCDC)and the European Centre for Disease Prevention and Control(ECDC)within maternal and child populations,and to explore the factors contributing to false-positive results in chemiluminescent immunoassays(CLIA).Methods A retrospective analysis was performed on serological test results from 109,003 patients collected between 2021 and 2023.All participants were initially screened for specific syphilis antibodies using CLIA,and those with positive results underwent confirmatory testing with both the toluidine red unheated serum test(TRUST)and the Treponema pallidum particle agglutination assay(TPPA).The kappa statistic was employed to assess the diagnostic agreement between the USCDC and ECDC protocols,while also analyzing the distribution patterns of CLIA false-positive results across varying S/CO value ranges and demographic groups.Results Both protocols achieved a syphilis positivity rate of 0.34%.The hospital's high-prevalence syphilis screening program identified no cases with CLIA-positive or TRUST-positive but TPPA-negative results,suggesting high specificity in this population.The two protocols demonstrated perfect agreement with a Kappa value of 1.0,indicating no significant difference in diagnostic performance between maternal and child populations.CLIA exhibited a true positive rate of 71.04%,which was positively correlated with S/CO values:21.88%when 1.010.The highest false positive rate for CLIA(38.75%)was observed among young adults,while the largest proportion of false positives-reaching 40.00%—was associated with pregnancy and abortion status.Conclusions The two reverse detection methods for syphilis exhibit comparable diagnostic efficacy in women and children from populations with low syphilis prevalence.CLIA demonstrates high sensitivity;however,when the S/CO ratio is less than 10,particularly in adult women of childbearing age,clinicians should remain vigilant for potential false-positive results to prevent misdiagnosis and unnecessary medical interventions.

It is difficult to treat severe burn combined injury caused by high voltage. This paper reports the successful treatment of a patient with large cranial area third degree burn, skull exposure, local skull carbonization combined with cerebrospinal fluid leakage caused by ten thousand volts high voltage current. Vacuum sealing drainage was given to protect the wounds from infection after multiple limited debridement in the early stage. The external of the inactivated skull was cleaned in the later stage. Finally, the bilateral anterolateral thigh flap combined with multiple burr holes was used to repair the wound. There were no severe postoperative complications, and the therapeutic effect was satisfactory.

It is difficult to treat severe burn combined injury caused by high voltage. This paper reports the successful treatment of a patient with third degree burn of extra large cranial area, skull exposure, local skull carbonization combined with cerebrospinal fluid leakage caused by ten thousand volts high voltage current. Vacuum sealing drainage was given to protect the wounds from infection after multiple limited debridement in the early stage. The external plate of the inactivated skull was cleaned in the later stage. Finally, the bilateral anterolateral thigh flap combined with multiple burr holes was used to repair the wound. There were no severe postoperative complications, and the therapeutic effect was satisfactory.

Objective:To study the differences of intestinal flora between neonatal rats with intrauterine hypoxia and healthy neonatal rats using high-throughput sequencing technology to determine the effects of intrauterine hypoxia on neonatal intestinal flora.Methods:Intrauterine hypoxia model were established in neonatal rats. On d1 and d7 after birth, intestinal samples were collected from intrauterine hypoxic group and normal control group and assigned into INH1 group (intrauterine hypoxia d1), INH7 group (intrauterine hypoxia d7), NOR1 group (normal control d1) and NOR7 group (normal control d7). 16S rRNA sequencing were conducted using these samples and the differences in the diversity, richness and composition of the flora among the groups were compared.Results:(1) The Alpha diversity of the intestinal flora in the INH1 group was higher than the NOR1 group. Specifically, both sobs and chao indices, representing the richness of the flora, in INH1 group were significantly higher than the NOR1 group (sobs index: 114.5±35.6 vs. 50.5±21.3, chao index: 135.6±38.5 vs. 73.9±28.8)( P<0.05). Compared with the NOR7 group, the mean values of sobs, ace, chao, simpson and shannon indices in the INH7 group showed no significant differences ( P>0.05). (2) At the phylum and genus level, the dominant bacterial groups in the intrauterine hypoxia group on d1 were firmicutes and streptococcus and proteus and escherichia for the normal control group. The difference of intestinal flora between intrauterine hypoxia group and the normal control group on d7 was smaller than the difference between the two groups on d1. Compared with INH1 group, the INH7 group had increased escherichia composition and decreased streptococcus composition. Conclusions:Intrauterine hypoxia changes the initial colonization and later affects the abundance and structural composition of the intestinal flora in newborn rats.

Taking the curriculum "society, the individual & medicine" in university of Ottawa faculty of medicine as an example, the cultivation models for comprehensive quality of medical students in China and Canada was compared. In University of Ottawa faculty of medicine, the curriculum "society, the individual & medicine" is throughout the whole medical education, including three themes of statistics and epidemiology related knowledge, health related issues and professional development. The varied teaching modes are combined with electronic teaching equipment and students' subjectivity in learning is emphasized. Drawing insights from the medical education in Canada, we should focus on promoting early contact and lifelong study of medical humanities curriculum for medical students, enriching the curriculum content, enhancing the curriculum practicality, diversifying the teaching methods, strengthening the teachers' training, improving the assessment system and establishing the long-term mechanism.
