Objective:To assess the efficacy and safety of pain control nursing for burn patients.Methods:Databases including CNKI, Wanfang Data Knowledge Service Platform, Weipu Database, China Biomedical Literature Database, Web of Science and Cochrane Library were searched to collect the literature on pain control nursing of burn patients from their inception to December 31, 2024. Literature screening, data extraction and quality assessment were performed independently by 2 researchers based on inclusion and exclusion criteria. Meta-analysis of the included studies was performed by applying RevMan 5.4 software. The efficacy of pain control care was assessed in terms of improving care satisfaction, alleviating negative emotions, reducing pain, and decreasing infection rate. Publication bias was analyzed on the related studies.Results:A total of 9 papers were included, all of which were randomized controlled trial (RCT) studies, involving 791 burn patients, with 392 in the pain control nursing group and 399 in the conventional care group. Meta-analysis showed that compared with the conventional care, pain control nursing significantly increased satisfaction of care ( OR=0.28, 95% CI 0.22, 0.34), improved negative emotions ( SMD=-3.06, 95% CI -4.65, -1.47), reduced pain ( SMD=-2.49, 95% CI -3.41, -1.58), and effectively reduced the incidence of infection ( OR=0.13, 95% CI 0.05, 0.34). The studies related to negative emotions were at the risk of publication bias. Conclusion:Compared with conventional care, pain control nursing can significantly increase care satisfaction, alleviate negative emotions, reduce pain, and lower infection risk in burn patients.

Objective To investigate the role of long non-coding RNA 01004 (LncRNA01004) in accelerating the malignant progression of breast cancer cells and its potential regulatory mechanism. Methods Quantitative real-time polymerase chain reaction (qRT-PCR) was used to detect the expression level of LncRNA01004 in breast cancer tissues and cells. The Starbase online database predicted the binding of LncRNA01004 to CPSF1 and verified it through RNA binding protein immunoprecipitation(RIP) analysis. MCF-7 cells were transfected with LncRNA01004 interference sequence (sh-LncRNA01004) or overexpressed vector (LncRNA01004),or co-transfected with Cleavage and Polyadenylation Specific Factor 1 (CPSF1) interference sequence (sh-CPSF1). Cell viability,invasion and apoptosis were detected with CCK-8,Transwell and flow cytometry (FCM). The overexpression and silencing efficiency of LINC01004 and CPSF1 were detected by qPCR. Western blot (WB) analysis of CPSF1 protein,apoptosis-related protein[B cell lymphoma/leukemia-2(Bcl-2),Bcl-2 Associated X(Bax)]and Epithelial-Mesenchymal transition (EMT) related protein[Epitheia-cadherin(E-cadherin),Nerve-cadherin(N-cadherin),Vimentin,zinc-finger transcription factor(Snail)],and the activity of Cysteinyl aspartate-specific proteinase-3 (Caspase-3) was determined by enzyme-linked immunosorbent assay. Results LncRNA01004 was significantly up-regulated in breast cancer tissues (5.14±0.33) compared with paracancer tissues (1.02±0.03),with the statistically significant difference (t=-78.637,P<0.001);LncRNA01004 expression in breast cancer cells was significantly higher than that in normal breast epithelial cells,the difference between groups is statistically significant (F=142.248,P<0.001). Compared with the Control group,LncRNA01004 significantly inhibited the proliferation (42.15±2.11 vs 100.02±0.65) and invasion (18.65％±1.44％ vs 41.36％±1.57％) of MCF-7 cells,induced apoptosis (16.58％±1.52％ vs 5.24％±1.12％),increased the activity of Caspase-3 (2.93±0.711. vs 51±0.43) and the expression of Bax (2.74±0.39 vs 1.01±0.02) protein,and inhibited the expression of BcL-2 (0.32±0.07 vs 1.02±0.03) protein,with the statistically significant difference (t=3.075～19.332,all P<0.05). Significantly increased compared with Control group,the silent LncRNA01004 E-cadherin (3.06±0.37 vs 1.01±0.02) protein levels,lower N-cadherin (0.44±0.11 vs 1.00±0.01),Vimentin (0.39±0.13 vs 1.02±0.03) and Snail(0.30±0.08 vs 1.01±0.03) protein levels,with the statistically significant difference (t=9.989～17.164,all P<0.05).LncRNA01004 binds to CPSF1 and promotes CPSF1 protein expression.Silencing CPSF1 inhibited the proliferation and invasion of MCF-7 cells,induced cell apoptosis,and counteracted the effect of LncRNA01004 overexpression on MCF-7 cells. Conclusion LncRNA01004 may promote EMT through up-regulation of CPSF1,and then promote proliferation and invasion of breast cancer cells,inhibit cell apoptosis,and participate in the malignant progression of breast cancer.

Objective: To perform an epidemiological survey of the first case with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection in Pinghu City of Jiaxing City, Zhejiang Province on March 13, 2022, so as to provide insights into the management of coronavirus disease (COVID-19) epidemics. Methods: According to the requirements of the Protocol on Prevention and Control of COVID-19 (8th Edition), epidemiological investigations were performed among 39 cases with SARS-CoV-2 infections in Pinghu City from March 13 to 20, 2022. Cases' demographics, clinical symptoms, history of immunization and exposure were collected, and close contacts were identified. Pharyngeal swabs were sampled from infected cases for detection of SARS-CoV-2 nucleic acid and whole-genome sequencing, and the source of infection and transmission route were investigated. Results: The index case for this COVID-19 epidemic was an imported case from Shanghai Municipality, who infected 6 persons via aerosol transmission when playing in the badminton venue of Pinghu National Fitness Center on March 9; subsequently, one of these infected cases infected another 18 persons when playing in the badminton venue of Jiadian Village Resident's Fitness Center in Zhapu Township on March 12. Sixteen confirmed cases were reported, and all cases were mild; another 23 asymptomatic cases were diagnosed, with no death reported. This epidemic occurred from March 11 to 20, with 3 generations of spread and a median incubation period of 3 days. The SARS-CoV-2 infected cases had a median age of 33.5 (interquartile range, 12.0) years and included 36 cases with a history of COVID-19 vaccination. There were 16 cases with fever, cough, runny nose and sore throat, and 13 cases with imaging features of pneumonia. The effective reproductive number (Rt) of the COVID-19 epidemic was 7.73 at early stage, and was less than 1 since March 21. Whole-genome sequencing identified Omicron BA.2 variant among 33 cases, which had high homology with the index cases. Conclusion This epidemic was a cluster of COVID-19 caused by imported Omicron BA.2 variant infection from Shanghai Municipality, and the COVID-19 transmission was mainly caused by indoor aerosols.

Objective:To compare the effects of five different types of videolaryngoscopes in patients with a simulated difficult airway.Methods:575 patients who needed endotracheal intubation in Nanjing Hospital Affiliated to Nanjing Medical University from May 2021 to September 2021 were randomly divided into 5 groups [UE videolaryngoscope group (U group), GlideScope videolaryngoscope group (G group), C-MAC videolaryngoscope group (C group), Airtraq videolaryngoscope group (A group) and A. P.advance videolaryngoscope group (AP group)], with 115 patients in each group. They all wore cervical collar to simulate difficult airway. The main observation index was the success rate of first endotracheal intubation. Secondary observation indicators included overall success rate, laryngoscope exposure field, intubation time, operator′s subjective score, cause of failure, adverse events, and complications of intubation.Results:The patients′ mouth opening degree was reduced from (46±6)mm to (24±4)mm ( P<0.05) after wearing the cervical collar; The success rate of the first endotracheal intubation were 96%(UE), 92%(C-MAC), 86%(GlideScope), 85%(Airtraq), and 60%(AP.Advance) respectively, with statistically significant difference ( P<0.05); Compared with AP group and G group, the incidence of soft tissue injury or bleeding in U group and C group were lower ( P<0.05); There were significant difference in the overall success rate of videolaryngoscopes, laryngoscope visual field exposure, intubation time, the subjective score of the operator and adverse events ( P<0.05); There was no significant difference in the complications of intubation among the groups ( P>0.05). Conclusions:Among 575 patients with a simulated difficult airway with limited neck mobility and limited mouth opening, there were significant differences in the use of five videolaryngoscopes. Among them, UE video laryngoscope had the highest first intubation success rate and lowest tissue trauma rate, C-MAC video laryngoscope, GlideScope video laryngoscope and Airtraq video laryngoscope followed in performance, while A. P.Advance video laryngoscope performed the worst.

OBJECTIVETo explore the pathogenesis of a child with growth retardation, liver damage and congenital heart disease.

METHODSG-banded chromosomal karyotyping, high-throughput next-generation sequencing (HT-NGS)and fluorescence in situ hybridization(FISH) were used to characterize the structural chromosomal aberration.

RESULTSThe child was found to have a karyotype of 46, XX, t(1;2) (q25;q21), t(7;20) (q21;p13). HT-NGS has detected a microdeletion at 2q21.3 and 7q21.11, respectively, which were verified by FISH.

CONCLUSIONCombined cytogenetic and molecular analysis can detect chromosome micrdeletions more precisely. The abnormalities of the child may be attributed to heterozygous deletion of ZEB2, ABCB4 and SEMA3A genes.
