As a common clinical treatment technique, nasogastric tube insertion plays an important role in assisting in disease diagnosis and treatment, and promoting patient recovery. Nasogastric tubes currently used in clinical practice are packaged individually without accompanying sterile materials, hence additional materials need to be prepared before operation, which is complicated and prone to omission, consumes clinical manpower, and increases the proportion of departmental consumption. The operator needs to hold the nasogastric tube with one hand and place it with the other hand during operation, the lack of auxiliary tool for uniformly controlling the placement of gastric tubes may easily lead to tube failure due to patient intolerance, agitation, or uneven force exerted by the operator, and improper force may even result in violent tube placement, leading to adverse outcomes such as mucosal bleeding and aspiration into the airway. Medical staff of intensive care unit of department of infectious diseases of Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology have designed a nasogastric tube auxiliary pushing device and an intubation kit to overcome the above problems, and obtaining National Utility Model Patent of China (patent number: ZL 2024 2 0300856.X). The device consists of two parts: a nasogastric tube auxiliary pushing device and a nasogastric tube insertion kit. Nasogastric tube auxiliary pushing device mainly consists of a nasogastric tube with guide wire, a circular wire harness, and a booster base with a pushing element. The tube insertion kit includes sterile treatment trays, main placement slots, and other operational accessory slots. The new nasogastric tube auxiliary pushing device and tube insertion kit integrates packaging and portable design, providing stable and uniform assistance for safe insertion of nasogastric tubes by a single person, which is able to reduce the occurrence of complications, ensure patient safety, improve patient comfort, and reduce occupational exposure risks, making it suitable for clinical promotion.

Adolescents and young adults (AYAs) are one of the major populations susceptible to tuberculosis. However, little is known about the unique characteristics and diagnostic biomarkers of tuberculosis in this population. In this study, 81 AYAs were recruited, and the high-quality serum proteome of the AYAs with tuberculosis was profiled by quantitative proteomics. The data of serum proteomics indicated that the relative abundance of hemoglobin and apolipoprotein was significantly reduced in the patients with active tuberculosis (ATB). The pathway enrichment analysis showed that the downregulated proteins in the ATB group were mainly involved in the antioxidant and cell detoxification pathways, indicating extensive oxidative stress damage. Random forest (RF) and extreme gradient boosting (XGBoost) were employed to evaluate protein importance, which yielded a set of candidate proteins that can distinguish between ATB and non-ATB. The analysis with the support vector machine algorithm (recursive feature elimination) suggested that the combination of apolipoprotein A-I (APOA1), hemoglobin subunit beta (HBB), and hemoglobin subunit alpha-1 (HBA1) had the highest accuracy and sensitivity in diagnosing ATB. Meanwhile, the levels of hemoglobin (HGB) and albumin (ALB) can be used as blood biochemical indicators to evaluate changes in the protein levels of APOA1 and HBB. This study established the serum proteome landscape of AYAs with tuberculosis and identified new biomarkers for the diagnosis of tuberculosis in this population.

Objective:To study the clinical manifestations and genetic characteristics of neonatal-onset primary mitochondrial disease (PMD) caused by nuclear gene mutations.Methods:From May 2020 to March 2022, the clinical data, genetic results and follow-up information of neonates with PMD admitted to the Department of Neonatology of our two hospitals were retrospectively analyzed.Results:A total of 4 patients were enrolled, all with hyperlactatemia and metabolic acidosis. In case 1, the fetal cranial MRI showed agenesis of corpus callosum. In case 2, echocardiography after birth indicated hypertrophic cardiomyopathy. Whole exome sequencing found the following mutations: EARS2 nuclear gene c.1294C>T and c.971G>T variants, COA6 nuclear gene c.411_412insAAAG variant, ACAD9 nuclear gene c.1278+1G>A and c.895A>T variants, FOXRED1 nuclear gene c.1054C>T and c.3dup variants. Mitochondrial second-generation sequencing and multiplex ligation-dependent probe amplification showed no abnormalities. Cases 1 and 3 died during the neonatal period. Case 2 died at 2-year-and-2-month of age. Case 4 was followed up to 1 year of age with developmental delay.Conclusions:The main phenotypes of neonatal-onset PMD caused by nuclear gene mutations are hyperlactatemia, refractory metabolic acidosis and cardiomyopathy, which have a poor prognosis. Proactive genetic tests are helpful for early diagnosis.

【Objective】 To explore the expressions of PBRM1 and PD-L1 in renal cell carcinoma (RCC), and the molecular mechanism of PBRM1 regulating PD-L1, in order to provide experimental results for clinical immunotherapy. 【Methods】 The protein expressions of PBRM1 and PD-L1 were detected with immunohistochemistry, and their mRNA expressions were determined by analyzing TCGA database. Meanwhile, the relationship between overall survival and mRNA expressions of PBRM1 and PD-L1 were analyzed in TCGA database. The exosomes were extracted with exoEasy Maxi Kit. Expressions of exosomal biomarkers CD63 and CD9 were detected with Western blotting, and their morphology was observed with transmission electron microscope. PD-L1 expression after IFN-γ, IL-6 and TNF-α treatment was detected with Western blotting. 【Results】 The expression of PBRM1 was significantly lower in canver tissue than in paracancerous tissue (P<0.001). The loss rate of PBRM1 was up to 76.4%. PBRM1 expression was not correlated with PD-L1 expression. PBRM1 deletion activated TNF-α/exosome signaling pathway, leading to increase of PD-L1 secretion in exosomes, which was then transported to the outside of cells. 【Conclusion】 There is no relationship between PBRM1 and PD-L1 protein expressions in RCC. However, PBRM1 mutation can lead to inflammatory signaling pathway activation, inducing PD-L1 secretion, which is encapsulated in exosomes and transported to the outside of cells, and affects the response of immunotherapy.

Objective:To study the clinical characteristics of different types of neonatal sepsis.Methods:From January 2012 to December 2019, neonates with confirmed sepsis from 5 neonatal centers of central-south China were reviewed. The neonates were assigned into early-onset sepsis (EOS) and late-onset sepsis (LOS) group, and the latter was further subgrouped into hospital-acquired LOS (hLOS) group and community-acquired LOS (cLOS) group. The etiological and clinical characteristics were analyzed. SPSS 26.0 was used for statistical analysis.Results:A total of 580 neonates were enrolled, including 286 (49.3%) in the EOS group and 294 (50.7%) in the LOS group. In LOS group, 147 were in hLOS group and 147 were in cLOS group. The gestational age and birth weight of hLOS group were significantly lower than the other two groups [(32.7±3.6) weeks vs. (37.1±3.7) weeks and (37.7±3.0) weeks, (1 810±717) g vs. (2 837±865) g and (3 024±710) g] ( P<0.05). The common pathogens in EOS and cLOS groups were coagulase-negative staphylococci and Escherichia coli, while Klebsiella pneumoniae was common in hLOS group. Carbapenems usage in the hLOS group was significantly higher than the other two groups [62.6% vs. 28.7% and 16.2%] ( P<0.05). Antibiotics duration in the hLOS group was longer than the other two groups [19 (14, 27) d vs. 15 (12, 20) d and 14 (12, 19) d] ( P<0.05). Conclusions:The clinical characteristics of neonatal sepsis vary among different types of infections, and it is necessary to establish appropriate prevention, control, diagnosis and treatment protocols.
