Objective:To assess the efficacy and safety of azacitidine combined with lenalidomide in MDS patients and explore potential mechanisms of therapeutic response.Methods:Sixteen MDS patients with TP53 mutations received azacitidine plus lenalidomide at ZhongDa Hospital, Southeast University (January 2021–June 2025). Efficacy and safety were assessed, and TP53 mutation status was correlated with treatment response. Whole-transcriptome sequencing and bioinformatics were used to explore molecular biomarkers associated with therapeutic efficacy.Results:Sixteen patients (median age 69.5 years, range 52–82; 8 males, 8 females) were enrolled. According to the Molecular International Prognostic Scoring System (IPSS-M), 1, 2, and 13 patients were classified as median low, high, and very high risk, respectively. Among 16 TP53-mutated patients, 11 had biallelic mutations and 5 had monoallelic mutations. Overall response rate was 56.3% (9/16), composite complete remission rate (CRc) was 31.3% (5/16), and hematology improvement rate was 25% (4/16). Among TP53-mutated patients, the response rate was 56.3% (9/16), with variant allele frequency dropping from 65.6% to 16.5% in responders ( P=0.017). In patients with TP53 mutations and complex karyotype, response rate was 53.8% (7/13), with 57.1% (4/7) showing disappearance of CK post-treatment. The most common grade 3–4 nonhematologic adverse events were infections (9/16, 56.3% ), including pneumonia (4/16, 25.0% ), gastrointestinal infections (3/16, 18.8% ), perianal infections (1/16, 6.3% ) and sepsis (1/16, 6.3% ). High CBX8 expression may be linked to treatment response. Conclusion:Azacitidine plus lenalidomide is an effective and safe therapy for MDS, including patients with TP53 mutations and complex karyotypes. Treatment markedly reduces TP53 variant allele frequency in responders, and high CBX8 expression may predict therapeutic response.

Objective:To summarize the clinical characteristics of children with mitochondrial short-chain enoyl-CoA hydratase-1 deficiency (ECHS1D) caused by c.489G>A (p.Pro163=) compound heterozygous variants in the ECHS1 gene, and to explore genotype-phenotype correlations.Methods:A case series study was performed to analyze clinical, biochemical, metabolic, imaging, genetic, treatment and follow-up outcomes of 24 children with ECHS1 gene c.489G>A(p.Pro163=) variant, who were diagnosed in the Department of Neurology, Beijing Children′s Hospital from July 2010 to June 2024. Disease severity was assessed using the Newcastle Paediatric Mitochondrial Disease Scale, and Fisher exact test was applied to compare the improvement rate between valine-restricted and non-restricted groups.Results:These 24 children were all diagnosed after 2022, with a disease duration of 3.35 (1.25, 6.52) years at diagnosis. A total of 8 children initially had negative genetic results, and were finally confirmed by abnormal splicing of ECHS1 gene via skin fibroblast RNA sequencing, with the longest diagnostic time of 14 years. All 24 children presented with Leigh syndrome, including 11 boys and 13 girls, with an onset age of 1.46 (0.96, 2.79) years; 16 children (67%) were mild cases. Common initial symptoms included developmental delay (9 cases) and paroxysmal dystonia (9 cases), followed by developmental regression (3 cases), nystagmus (2 cases), and epilepsy (1 case). Main manifestations were dystonia (18 cases), developmental regression (14 cases), nystagmus (12 cases), developmental delay (11 cases), ataxia (10 cases), vision loss (9 cases), seizures (2 cases), and hearing impairment (1 case). Among 22 children who underwent blood and urine metabolic screening, 21 children (95%) had elevated urinary 2, 3-dihydroxy-2-methylbutyric acid and 19 children (86%) had elevated urinary S-(2-hydroxypropyl) cysteamine. All 24 children had symmetric abnormal signals in bilateral globus pallidus on cranial magnetic resonance imaging, 10 children had isolated globus pallidus involvement, and other common involved sites included caudate nucleus and brainstem (9 cases each), putamen (7 cases), and cerebral white matter (5 cases). At last follow-up, all 24 children survived, with a follow-up duration of 5.40 (2.75, 8.02) years and a maximum age of 17.8 years; 17 children (71%) had varying degrees of clinical improvement. There was no statistical difference in the improvement rate between children with or without valine-restricted diet (12/14 vs. 5/8, P=0.309). A total of 18 pathogenic variants in the ECHS1 gene were identified among 24 children, 13 of which were distributed in exons 7 and 8; those carrying c.308T>C, c.523G>A, c.796A>G, and c.832G>A variants were mostly severe cases. Conclusions:Children carrying ECHS1 gene c.489G>A(p.Pro163=) compound heterozygous variants face significant diagnostic delay. Clinical awareness of this synonymous variant needs further improvement for timely diagnosis. All these cases present as Leigh syndrome, mostly mild, with no clear genotype-phenotype correlation identified.

Objective:To evaluate the quality of critical patient handover practice between emergency room and intensive care unit (ICU) nurses, and to provide a basis for structured handover process.Methods:From March to July 2023, a total of 223 pairs of nurses in emergency room and ICU (including EICU) of 5 Class 3 Grade A general hospitals in Suzhou were selected as the research objects by using cross-sectional survey method and convenience sampling method. Self-designed general information questionnaire and Patient Handover Practice Quality Scale were used to investigate the included 223 pairs of nurses in emergency room and ICU on the current situation of handover time and quality.Results:A total of 211 pairs of nurses were included, including 286 females (67.8%) and 136 males (32.2%). The average age of emergency department nurses was (27.31 ± 2.17) years old, and ICU nurses was (26.96 ± 3.04) years old. The total scores of the patient handover practice Quality Scale for nurses in the emergency room and ICU were (45.25 ± 6.26) and (43.55 ± 7.19) points respectively, and the scores of the information transmission dimension were (20.47 ± 5.43) and (17.66 ± 3.45) points. The scores of common understanding dimension were (7.59 ± 2.31) and (8.58 ± 2.46) points. The scores of work atmosphere dimension were (7.93 ± 2.11) and (8.39 ± 2.29) points. The scores of handover situation dimension were (5.33 ± 1.30) and (5.70 ± 1.53) points, and the differences were statistically significant ( t values were - 6.35-4.22, all P<0.05). There were statistically significant differences in the scores of handover practice quality between emergency room nurses and ICU nurses according to specialization, education background, working years and job category ( t values were - 4.91-2.56, all P<0.05). Conclusions:Emergency room nurses and ICU nurses have different requirements and expectations for handover procedures, so it is necessary to build a structured handover practice framework and carry out personalized handover practice training, in order to achieve the consistency of handover content and improve the quality of critical patients handover practice.

ObjectiveTo explore the influence of electroacupuncture combined with point bloodletting and cupping for facial nerve function recovery in acute stage of idiopathic facial palsy (IFP). MethodsEighty patients with IFP in the acute stage were randomly divided into 40 cases each in the treatment group and the control group. In the control group, oral prednisone acetate tablets were administered during the acute stage when the disease duration was less than 10 days; and electroacupuncture and flash cupping were provided during the recovery stage when the disease duration was more than 10 days, five times a week. For treatment group in acute stage, the stellate ganglion, vagus nerve stimulation point in the auricular cavity, Yifeng (TE 17) and Tinghui (GB 2) were needled on the affected side on the basis of the treatment of control group, with Yifeng and Tinghui connecting to electroacupuncture apparatus, once a day; point bloodletting and then cupping in Yifeng 2 times a week; in recovery stage, the treatment was the same as that of the control group. Both groups were treated until the 45th day from onset. The primary outcome was the Toronto facial grading system (SFGS), and the secondary outcomes included house-brackmann (H-B) grade, facial disability index (FDI) score, and number of H-B grade-Ⅰ cases. Adverse events were recorded in both groups. ResultsThe SFGS scores of the patients in both groups were higher on the 10th, 30th and 45th days after onset of disease compared with those before the treatment (P<0.05); the H-B grade was lower on the 30th and 45th days after the onset of the disease compared with those before the treatment (P<0.05); and the facial disability index physical function (FDIP) and facial disability index social function (FDIS) scores were higher on the 30th and 45th days after onset of disease (P<0.05). SFGS scores of patients in the treatment group were significantly higher than those of the control group on the 30th and 45th days after onset (P<0.05); H-B grade was significantly lower than that of the control group on the 30th and 45th days after onset (P<0.05); and FDIP scores on the 45th day after onset, and FDIS scores on the 30th and 45th days after onset were significantly higher than those of the control group (P<0.05). At the end of treatment, 77.50% (31 cases) achieved H-B grade-Ⅰ in the treatment group, which was more than 55.00% (22 cases) in the control group (P<0.05). No adverse events occurred in either group. ConclusionElectroacupuncture combined with point bloodletting and cupping for IFP in acute stage can improve the recovery degree of facial nerve function, improve effectiveness, and show a high degree of safety.

OBJECTIVE:
To evaluate the efficacy and safety of magnesium sulfate in the treatment of acute severe asthma in adults.
METHODS:
Literature searches were conducted on PubMed, Cochrane, CNKI, VIP and Wanfang databases to screen randomized controlled trial (RCT) of magnesium sulfate in the treatment of acute severe asthma in adults, starting from the establishment of the database and ending on May 22, 2024. The control group received conventional treatment. The observation group was given intravenous magnesium sulfate on the basis of routine treatment. The outcome indexes included total effective rate, peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), forced vital capacity (FVC) and other pulmonary function indexes, and incidence of adverse reactions. The selection of relevant literature, the collection of data needed for the study and the risk assessment of bias in the included study were all conducted independently by 2 researchers. Stata 12.0 software was used for Meta-analysis, and funnel plot was used to evaluate publication bias.
RESULTS:
Sixteen RCT studies with a total of 2 601 patients were included. Meta-analysis results showed that the total effective rate in the observation group was significantly higher than that in the control group [risk ratio (RR) = 1.11, 95% confidence interval (95%CI) was 1.03-1.20, P = 0.008]. In pulmonary function examination, PEF [weighted mean difference (WMD) = 0.70, 95%CI was 0.24-1.15, P = 0.003], FEV1 (WMD = 0.48, 95%CI was 0.29-0.68, P = 0.000) and FVC (WMD = 0.72, 95%CI was 0.47-0.97, P = 0.000) were significantly better than those in the control group. There was no significantly difference in the incidence of adverse reactions between the two groups (RR = 0.51, 95%CI was 0.17-1.55, P = 0.419). The funnel plot was drawn for the total effective rate, which showed that each study presented a symmetrical distribution, and the Begg's test (Z = 1.31, P = 0.189) and Egger's test (t = 1.18, P = 0.261) were combined to consider the small possibility of publication bias.
CONCLUSIONS
Current evidence shows that the use of magnesium sulfate in the treatment of acute severe asthma in adults increases the total response rate and improves lung function without increasing the incidence of adverse reactions. Due to the limited number and quality of included studies, the above conclusions need to be verified by more high-quality studies high-quality studies.
