Objective To observe the effect of different concentration sodium bicarbonate gastric lavage on newborn with swallow syndrome.Methods 88 patients from our hospital were enrolled in this study.They were randomly divided into control group (A group) and experimental groups(B、C、D、E group) according to numerical table.Separately using water and 1.0%, 1.5%, 2.0%, 2.5% sodium bicarbonate solution gastric lavage.Vomiting, abdominal distention, gastric retention and weight changes was observed.Results The result showed that the vomiting, abdominal distention, gastric retention of patients in experimental group were better than that of patients in control group, and there were significant differences between them(p<0.05).but there were no significant difference among the experimental groups (p>0.05).And there were no significant difference among experimental and control groups in weight changes(p>0.05).Conclusion 1%sodium bicarbonate can much shorten the time to stop vomit and reduce complication.Therefore it is highly recommended and popularized.

Objective To explore the bloodstream infection of refractory drug-resistant Pseudomonas aeruginosa(DTR-PA)patients with clinical characteristics and risk factors.Methods Clinical data of patients with Pseudomonas aeruginosa bloodstream infection in the First Affiliated Hospital of Sun Yat-sen University from January 2017 to December 2022 were retrospectively analyzed.Multivariate Logistic regression analysis was used to explore the independent risk factors for DTR-PA bloodstream infection.Cox proportional hazards regression was used to explore the risk factors related to the death of Pseudomonas aeruginosa bloodstream in-fection.Results A total of 114 patients with Pseudomonas aeruginosa bloodstream infection were enrolled,with an average age of(51.05±17.55)years.The 28 d mortality was 14.0％(16/114),and 24 patients(21.1％,24/114)had DTR-PA.Age,ICU admission,diabetes,hypoproteinemia and septic shock were associ-ated with DTR-PA bloodstream infection(P＜0.05).Multivariate Logistic regression analysis showed that septic shock was an independent risk factor for DTR-PA bloodstream infection(P＜0.05).ICU admission was an independent risk factor for the death of patients with DTR-PA and Pseudomonas aeruginosa blood-stream infection(P＜0.05).Conclusion There are many risk factors for DTR-PA bloodstream infection.Septic shock and ICU admission are independent risk factors for DTR-PA bloodstream infection and death,respectively.

Objective To establish the reference intervals for test indicators of thyroid function,namely thyroid stimulating hormone(TSH),free thyroxine(FT4),and free triiodothyronine(FT3),in the children aged 0 to 15 years old in Nanning,China.Methods A total of 1 289 healthy children aged 0 to 15 years old who attended the Guangxi International Zhuang Medicine Hospital Affiliated with Guangxi University of Chinese Medicine from October 2018 to August 2023 were selected.The concentrations in serum TSH,FT4,and FT3 were measured by chemiluminescent microparticle immunoassay(CMIA).According to the Clinical and Laboratory Standards Institute(CLSI)EP28-A3c guideline,the nonparametric percentile method was used to establish the reference intervals for TSH,FT4,and FT3 in the children aged 0 to 15 years old in Nanning area.Results The established reference intervals were as follows:TSH(male):0 to＜1 month:0.88-7.81 μIU/mL,1 month to 15 years:0.59-5.06 μIU/mL;TSH(female):0 to＜1 month:0.93-8.42μIU/mL,1 month to 15 years:0.60-4.30 μIU/mL.FT4(male):0 to＜1 month:0.99-1.92 pg/mL,1 month to 15 years:0.86-1.33 pg/mL;FT4(female):0 to＜1 month:1.05-2.06 pg/mL,1 month to 15 years:0.85-1.37 pg/mL;FT3:0 to＜1 month:2.16-4.24 pmol/L,1 month to＜11 years:2.75-4.49 pmol/L,11 to 15 years:2.45-4.34 pmol/L.Significant differences were observed among different gender and age groups for TSH,FT4,and FT3 levels(P＜0.05).Conclusion This study successfully established the refer-ence intervals of TSH,FT4,and FT3 in the children aged 0 to 15 years old in Nanning area,which were significantly different among various gender and age groups.

Objective:To explore the value of coronary artery plaque progression parameters based on coronary CT angiography (CCTA) in predicting the occurrence of major adverse cardiovascular events (MACE) in patients with non-obstructive coronary artery disease.Methods:The study included clinical, imaging, and prognosis (MACE) parameters of non-obstructive coronary artery disease patients who underwent CCTA at the First Affiliated Hospital of Nanjing Medical University from September 2010 to December 2022. Patients were grouped based on the occurrence of MACE, and differences in clinical data, plaque baseline, and progression parameters between the two groups were compared. Univariate and multivariate Cox regression analyses were employed to identify factors that could effectively predict the occurrence of MACE in patients. Models were constructed using plaque baseline parameters, plaque progression parameters, and a combination of both. The concordance index-time curve, net reclassification improvement and integrated discrimination improvement were used to evaluate the risk stratification ability of the models.Results:A total of 258 patients were included, of whom 62 cases experienced MACE during the follow-up period. In comparison to the MACE(-) group, patients in the MACE(+) group exhibited longer lesion length, greater degree of stenosis, larger plaque total volume, calcified plaque volume, non-calcified plaque volume, fibrous plaque volume, total plaque burden, lipid-rich plaque burden, higher peri-coronary adipose tissue attenuation index (FAI), and annual change of diameter stenosis(ΔDS/y). There were also more cases of coronary artery disease reporting and data system upgrades and non-obstructive progression to obstructive status ( P<0.05). Multivariate Cox analysis revealed that FAI, ΔDS/y, and non-obstructive progression to obstructive status were independent predictors of MACE occurrence. Concordance index-time curve results indicated that the combined model had a better predictive efficacy for MACE in patients with non-obstructive coronary artery disease compared to models based on plaque baseline parameters and plaque progression parameters. Conclusion:The plaque progression parameters and FAI based on CCTA have the potential to predict the high-risk population for MACE in patients with non-obstructive coronary artery disease, demonstrating good risk stratification value.

Objective:To retrieve and summarize the best evidence for nursing of hematopoietic stem cell reinfusion in children.Methods:Clinical decisions, guidelines, recommended practices, evidence summaries, systematic reviews, and expert consensuses on nursing of hematopoietic stem cell reinfusion in children were searched in Chinese and English databases as well as related websites such as British Medical Journal (BMJ) Best Practice, National Institute for Health and Clinical Excellence, National Guideline Clearinghouse, Guidelines International Network, Scottish Intercollegiate Guidelines Network, Joanna Briggs Institute Evidence-Based Health Care Center Database, UpToDate, CINAHL, Embase, PubMed, China National Knowledge Infrastructure, WanFang Data, and VIP. The search period was from database establishment to March 2023. Two researchers independently conducted literature quality evaluation, identified the included literature, extracted evidence item by item, and translated, organized and summarized the evidence.Results:A total of nine articles were included, including two clinical decisions, two expert consensuses, four guidelines, and one evidence summary. 24 pieces of evidence were summarized from six aspects, consisting of child preparation, stem cell preparation, item preparation, nursing during reinfusion, nursing after reinfusion, and evaluation and education.Conclusions:The best evidence for nursing of hematopoietic stem cell reinfusion in children involves a wide range of aspects. Managers, clinical medical and nursing staff should apply evidence based on specific medical situations in order to safely and reasonably perform hematopoietic stem cell reinfusion.
