Objective To analyze the epidemiological characteristics and immunization history of pertussis cases in Yichang City, Hubei Province from 2018 to 2023. Methods Data on the incidence and immunization history of pertussis cases were collected in Yichang City from 2018 to 2023, and the epidemiological characteristics was analyzed and described. Results A total of 109 cases of pertussis were reported in Yichang from 2018 to 2023, and the annual average reported incidence rate was 0.45/100,000. The incidence rate reported in each year was between 0～1.58/100,000. The area with the highest annual reported incidence rate was Xiling District (1.19/100,000). There was a statistically significant difference in the incidence rate between different years (χ²=208.26, P < 0.001). The annual reported incidence rate showed a significant increasing trend (χ² trend =125.71, P < 0.001). The ratio of male to female cases was 1.22. There was no significant difference in the annual reported incidence rates between males and females (χ²=0.85, P=0.36). Children aged 3-9 years accounted for 60.55%. Students and scattered children accounted for 45.87% and 36.70%, respectively. Before the onset of the disease, 72.48% had a history of immunization with pertussis-containing vaccine, and 27.52% had no history of immunization. The shortest interval between the last dose of pertussis-containing vaccine and the onset of the disease was 8 days, the longest was 4057 days, and the median was 1882 days. Conclusion From 2018 to 2023, the reported incidence of pertussis in Yichang City has been on the rise, with the majority of cases occurring in children and students under the age of 9. It is recommended to strengthen pertussis disease monitoring.

Objective:To investigate the factors affecting clinical pregnancy outcomes in fresh embryo transfer cycles of patients undergoing ovulation induction with antagonist protocol.Methods:Data from 1001 patients un-dergoing their first antagonist protocol fresh embryo transfer cycle at Department of Reproductive Medicine,The Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine,from December,2016 to June,2024 were collected.Patients were stratified into two groups based on pregnancy outcomes:clinical pregnancy(502 cases)and non-clinical pregnancy(499 cases).General characteristics,controlled ovarian stimulation pa-rameters,and laboratory data were analyzed.Independent factors affecting clinical pregnancy were identified through univariate analysis and multivariate binary Logistic regression analysis.Results:Multivariate binary Logis-tic regression analysis indicated that advanced maternal age(≥35 years)and HCG-day progesterone(P)levels were identified as inhibitory factors for clinical pregnancy(OR 0.571,95％CI 0.400-0.815,P＜0.05;OR 0.832,95％CI 0.720-0.961,P＜0.05).Endometrial thickness on HCG-day,2PN cleavage rate,and the number of trans-ferable embryos were significant positive predictors of clinical pregnancy(OR 1.095,95％CI 1.011-1.186;OR 1.036,95％CI 1.006-1.067,P＜0.05;OR 1.122,95％CI 1.039-1.211,P＜0.05).Embryo transfer strategy signifi-cantly impacted outcomes:transferring one cleavage-stage embryo or one blastocyst resulted in lower pregnancy rates compared to dual cleavage-stage embryo transfer(OR0.359,95％CI 0.195-0.658,P＜0.05;OR 0.457,95％CI 0.285-0.733,P＜0.05).Conclusions:Maternal age,HCG-day P levels,endometrial thickness on HCG-day,2PN cleavage rate,number of transferable embryos and embryo transfer strategy are independent pre-dictors of clinical pregnancy in antagonist protocol of fresh cycles.Individualized treatment protocols should con-sider these factors and maternal-infant health priorities to optimize pregnancy success.

Gallbladder carcinoma(GBC)is one of the most common malignant tumors in the biliary system,which is difficult to diagnose in the early stage due to its high degree of malignancy,invasiveness and lack of specific clin-ical manifestations.In this paper,we summarize ultrasound,CT and other imaging manifestations in the early stage of GBC,and describe the role of protein markers and microRNA marker as biomarkers in the diagnosis of early GBC.The enhanced understanding of the relevant features might help to improve the accuracy of the diagnosis of early gallbladder carcinoma.

Objective:To explore the clinical, imaging, and genetic characteristics of an adult patient with sporadic Neuronal intranuclear inclusion disease (NIID).Methods:A patient who had visited the First People′s Hospital of Chenzhou on August 6, 2023 was selected as the study subject. Results of clinical examination, neuroimaging, and genetic testing were retrospectively analyzed along with a literature review. The number of GGC trinucleotide repeats in the 5′-untranslated region of the NOTCH2NLC gene was determined by GC-PCR. Results:The patient had presented with episodic encephalopathy, with enhanced magnetic resonance imaging showing enhancement features of the posterior cerebral cortex during the period of acute episode. Genetic testing revealed an increased number of GGC repeats ( n = 97) in the 5′- untranslated region of the NOTCH2NLC gene, which confirmed the diagnosis of NIID. Conclusion:Clinical attention should be paid to the enhanced MRI findings of patients with adult-onset NIID, for whom posterior cortical enhancement may be characteristic manifestation during the acute phase of encephalopathy-like episode.

As a practical carrier for promoting the tiered diagnosis and treatment model, the medical consor-tium is of great significance for balancing medical resources and boosting medical service efficiency. The construction of medical consortiums not only improves the accessibility of high-quality medical resources for patients, but also enhances the diagnostic and treatment level of member units. Meanwhile, it provides space for the leading hospital to adjust the structure of diseases and improve the level of discipline construction. As the core of medical insurance payment reform, DRG, through indicators such as the case mix index(CMI) and the number of diagnosis related group (DRG), provides objective and quantified data support for case management and disease structure optimization, thus effectively guiding the rational allocation of medical resources and the adjustmentof diseases and surgical types within the medical consortium. Comprehensive use of DRG evaluation indicators can construct a multidimensional medical consortium construction evaluation system, provides a clear direction for medical consortium cooperation, thereby promoting the overall healthy and sustainable development of medical consortiums and achieving a win-win situation for all parties involved. This paper, based on the "1+5+1" medical consortium cooperation model centered around Peking Union Medical College Hospital, utilizes DRG indicators to analyze the benefits for patients, member hospitals, and the leading hospital during the medical consortium construction process, with the hope of providing reference for the construction of a medical consortium evaluation system.
