Objective:To investigate the application and management status of midline catheters in 1 954 hospitals, providing a basis for optimizing intravenous therapy nursing practices.Methods:This study used convenience sampling. From November 2023, members of the Intravenous Therapy Nursing Professional Committee of the Chinese Nursing Association selected 1 954 hospitals across various regions of China. Questionnaire on the Current Status of Intravenous Therapy in Hospitals at All Levels designed by the committee, based on literature review and expert discussions, was used to collect data on intravenous therapy practices in different hospitals. Multiple response analysis was applied to analysis the results of multiple-choice questions, where response numbers represent the total number of times each option was selected, and response rates refer to the proportion of selected times for each option out of all selected responses.Results:A total of 1 954 questionnaires were distributed across 31 provinces/municipalities/autonomous regions, and 1 954 valid questionnaires were returned, achieving a 100.0% valid response rate. Among the hospitals surveyed, 844 used midline catheters. Regarding the skin disinfection area for midline catheter insertion, the highest response rate was for a range of>20 cm. The highest response rate for catheter insertion techniques was ultrasound-guided Seldinger puncture. The highest response rate for maintenance interval was once a week. The top three responses for nursing documentation related to midline catheters were informed consent for intubation, puncture record, and maintenance record. The most frequently chosen processes were catheter placement, maintenance, removal, and complication management processes. The qualification for midline catheter intravenous therapy specialist nurses was mostly obtained through specialized nurse training, followed by hospital-based and department-based training.Conclusions:The application of midline catheters has rapidly developed but still reveals some deficiencies, including the choice of puncture tools, infection control, and catheter maintenance. It is recommended to improve nursing documentation and management processes related to midline catheters, establish industry standards suitable for China's national conditions, and strengthen and standardize the specialized training of intravenous therapy nurses to promote the healthy development of intravenous therapy in China.

OBJECTIVE: To investigate the clinical phenotype and genetic characteristics of a Chinese pedigree affected with Cohen syndrome. METHODS: A proband who was admitted to Zhengzhou People's Hospital on June 2, 2021 due to intellectual disability and developmental delay, in addition with her younger sister and other family members, were selected as the study subjects. Clinical data of the proband and her younger sister were collected. Genomic DNA was extracted from peripheral venous blood and chorionic villi samples. Chromosomal abnormalities were detected with chromosomal microarray analysis (CMA). Whole exome sequencing (WES) and Sanger sequencing were carried out to detect candidate variants in the proband. With RNA extracted from the peripheral blood samples, VPS13B gene transcripts and expression were analyzed by PCR and real-time quantitative PCR. Prenatal diagnosis was carried out at 12 weeks' gestation. RESULTS: The proband was a 10-year-old female with clinical manifestations including development delay, obesity, severe myopia and peculiar facial features. Her sister was 3 years old with a similar phenotype. CMA revealed no chromosomal abnormality in the proband, while WES results revealed that the proband and her sister had both harbored compound heterozygous variants of the VPS13B gene, namely c.10076_10077delCA (p.T3359fs*29) and c.6940+1G>T, which were respectively inherited from their mother and father. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were classified as pathogenic (PVS1+PS4+PM4+PP1; PVS1+PM2_Supporting+PM3+PP1). In vivo splicing assay confirmed that the c.6940+1G>T variant has produced a frameshift transcript with skipping of exon 38. Compared with the control group, the expression of RNA in the peripheral blood of the proband's parents has decreased to 65% ~ 70% (P < 0.01), whilst that in the proband and her sister has decreased to 40% (P < 0.001). Prenatal diagnosis at 12 weeks of gestation has found that the fetus only harbored the heterozygous c.10076_ 10077delCA variant. CONCLUSION The c.10076_10077delCA (p.T3359fs*29) frameshift variant and c.6940+1G>T splicing variant probably underlay the Cohen syndrome in this pedigree. Genetic testing has facilitated the diagnosis of this disease.

Objective:To evaluate the recurrence patterns of esophageal squamous cell carcinoma (ESCC) after radical surgery and analyze the predictors of post-recurrence survival (PRS).Methods:A total of 382 ESCC patients who developed recurrence after radical surgery were retrospectively reviewed from January 2007 to December 2011. All of them received salvage treatment after recurrence. The Univariate analysis was determined using the Kaplan-Meier method and log-rank test. Multivariate prognostic analysis was determined using the Cox proportional hazard model.Results:The 1-, 3-, 5-year overall survival (OS) rates were 80.9%, 35.6% and 20.4%, respectively. The median survival time and recurrence time were 29.2 months and 15.0 months. The 1-, 3-, 5-year PRS rates were 37.7%, 14.6% and 11.9%, respectively. The median PRS time was 10.2 months. Locoregional recurrence was noted at 462 sites among 382 patients including 20.5% (95/462) of sites in supraclavicular LN (lymph node), 10.0% (46/462) in anastomosis, 56.1% (259/462) in mediastinal regional LN and 13.4% (62/462) in upper abdominal LN. There were 156, 43, 82 and 101 patients treated with salvage radiotherapy, chemotherapy, chemoradiotherapy and palliative care after recurrence, respectively. The univariate analysis showed that T stage, N stage, TNM stage, recurrence site, number of recurrent regions and treatment regimen after recurrence were significantly correlated with PRS ( χ2=5.336, 4.292, 8.067, 7.482, 4.093, 76.426, P<0.05). Patients receiving salvage radiotherapy with the median dose of 60 Gy, were divided into <60 Gy group and ≥ 60 Gy group. The ≥60 Gy group had a better PRS than <60 Gy group ( χ2=8.320, P<0.05). Multivariate analysis showed that number of recurrent regions and treatment regimen were independent prognostic factors of PRS. Conclusions:Mediastinal and supraclavicular regions were the most common sites of recurrence in ESCC patients after radical surgery. Salvage radiotherapy and chemoradiotherapy could significantly improve PRS in recurrent ESCC patients.

OBJECTIVE: To explore the molecular mechanism of a girl with developmental delay and intellectual disability. METHODS: Chromosomal karotypes of the child and her parents were analyzed with routine G-banding method. Their genomic DNA was also analyzed with array comparative genomic hybridization (aCGH) for chromosomal duplications/deletions. RESULTS: No karyotypic abnormality was detected in the child and her parents, while aCGH has identified a de novo 3.37 Mb deletion at 17p11.2 in the child. CONCLUSION The child was diagnosed with Smith-Magenis syndrome, for which RAI1 may be the causative gene.
