Objective To analyze the clinical characteristics of lung adenocarcinoma patients with positive EGFR mutations detected in pleural effusion.Methods We retrospectively analyzed the clinical characteristics including gender,age,smoking history,presence of other underlying diseases(such as COPD,cardiovascular disease,and diabetes),site of pleural fluid,feature of pleural fluid,and TNM stage in patients with lung adenocar-cinoma who had been admitted to the first Affiliated Hospital of Bengbu Medical College from 2020.01 to 2022.12 for the first time by the detection of EGFR mutation positive in pleural effusion.The data were statistically analyzed using the SPSS 26.0 software.Results A total of 126 patients were screened for enrollment,including 61 patients(48.41%)with EGFR exon 19 deletion mutation(19del),56 patients(44.44%)with exon 21 L858R mutation(21L858R),and 9 patients(7.14%)with non-classical mutations.Univariate analysis showed that the three muta-tion subtypes were statistically significant in terms of gender,age,smoking history,and presence of COPD(P<0.05 for all comparisons),but not in terms of pleural fluid site,feature of pleural fluid,tumor size,and presence of cardiovascular disease,diabetes mellitus,presence of distant metastases,and mediastinal lymph node metastases(P>0.05 for all comparisons);Multivariate analysis showed that 21 L858R mutation was more likely to be found in male,older age,non-smoking,and presence of COPD than 19del mutation;non-classical mutation was more likely to be found in male than 19del mutation.Conclusions There are significant differences among the three mutation subtypes in sex,age,smoking history,and presence of COPD,but not in pleural fluid location,feature of pleural fluid,tumor size,presence of cardiovascular disease or diabetes mellitus,presence of distant metastases,or medias-tinal lymph node metastases;Among lung adenocarcinoma patients with positive EGFR mutations in pleural fluid,21 L858R mutation mostly occurs in male,older age,non-smokers,and those complicated with COPD,while non-classical mutation mainly develops in male.However,more case studies are needed to confirm the above conclusions.

OBJECTIVE To establish characteristic chromatogram of Yao medicine Kadsura longipedunculata and the method for the content determination of its main component anwulignan， and evaluate the anti-inflammatory activity of anwulignan. METHODS HPLC method was performed with acetonitrile-0.5% phosphoric acid solution as the mobile phase for gradient elution. The characteristic chromatogram of K. longipedunculata was established and similarity was evaluated by Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 edition）. The content of anwulignan in K. longipedunculata was determined. Lipopolysaccharide induced RAW264.7 macrophages were selected as inflammatory cell model to investigate the effects of anwulignan on the levels of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β） and IL-6. RESULTS The similarities of characteristic chromatogram for 10 batches of K. longipedunculata ranged 0.901-0.994， and 9 common peaks were determined； 3 components were identified， such as changnan schisantherin E， kadsulactone A， anwulignan. The contents of anwulignan were （0.72±0.05）-（1.21±0.03） mg/g（n＝3）. Anwulignan of 0.125-0.5 μg/mL greatly decreased the levels of TNF-α， IL-1β and IL-6 in the supernatant of inflammatory model cells （P＜0.05 or P＜0.01）. CONCLUSIONS HPLC characteristic chromatogram of K. longipedunculata and the method for the content determination of anwulignan are all established， and anwulignan may be the active ingredient of anti-inflammatory effect in K. longipedunculata.

Objective:To explore the clinical characteristics and pathogenic variant in a child with Cantú syndrome (CS).Methods:A male who was admitted to the Children′s Hospital Affiliated to Zhengzhou University on February 23, 2022 was selected as the study subject. Clinical data of the child was collected. Peripheral blood samples of the child and his parents were collected and subjected to whole-exome sequencing (WES). Candidate variant was verified by Sanger sequencing. This study was approved by Medical Ethics Committee of the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-087).Results:The child, a 3-year-and-2-month-old male, was born with hirsutism, with heavy hair all over the body and peculiar facial features. Routine echocardiography 1 month before had discovered atrial septal defect. Sequencing revealed that the child has harbored a heterozygous c. 2438G>C (p.S813T) variant of the ABCC9 gene, which was de novo in origin. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c. 2438G>C variant was classified as likely pathogenic (PS2+ PM2_Supporting+ PP3). Conclusion:The heterozygous c. 2438G>C variant of the ABCC9 gene probably underlay the pathogenesis of CS in this child.

The development of multi-campus districts has become an important initiative for the country to expand high-quality medical resources and build a high-quality and efficient medical and healthcare service system,and is an important implementation path for the high-quality development of public hospitals.The symbiosis theory is highly applicable to multi-campus hospital development,and can provide a new perspective for the exploration of multi-campus hospital collaborative development.Through the construction of the symbiotic framework based on symbiotic unit,symbiotic interface,symbiotic environment and symbiotic model,it analyzed the symbiotic dilemma of multi-campus hospital collaborative development,and proposed the path of multi-campus hospital collaborative development,in order to provide reference for the subsequent construction and development of multi-campus hospital in China.
