【Objective】 The purpose of this study was to investigate the prevalence status of neonatal congenital heart disease (CHD) in Ningbo City, Zhejiang Province from 2017 to 2021, and to analyze the influencing factors, so as to provide reference for preventing the risk of CHD and reduce the prevalence of CHD. 【Methods】 Using cross-sectional survey method, the neonatal data from March 2017 to December 2021 were captured from Zhenjiang Neonatal Disease Screening Center, and were analyzed by linear trend chi-square test; binary Logistic regression was used to analyze the influencing factors of CHD. 【Results】 A total of 13 156 newborns screened positive for CHD in Ningbo, Zhejiang Province, with CHD confirmed in 6 300 cases. Among these, 3 066 cases were boys (48.7%) and 3 234 cases were girls (51.3%). The prevalence rates of neonatal CHD in Ningbo city for the years 2017, 2018, 2019, 2020, and 2021 were 2.07%, 1.10%, 2.00%, 2.04% and 1.08%, respectively, with an overall prevalence from 2017 to 2021 of 1.69%. The chi-square test for the linear trend indicated a decreasing prevalence of neonatal CHD over time(χ²=178.518,P<0.001). Multivariate analysis showed that maternal age [36 to 45 years(OR=1.24), >45 years(OR=1.66)], male infants (OR=1.26), premature birth [<32 weeks (OR=1.13), 32 - 36 weeks(OR=1.54)], and being a second birth (OR=2.56) were independent risk factors for the development of CHD (P<0.05). 【Conclusions】 The prevalence of CHD in Ningbo, Zhejiang Province is higher than that of CHD in China and other cities of Zhejiang Province. Although the prevalence showed a decreasing trend over time, targeted prevention and control measures need to be implemented to reduce the prevalence of CHD.

[Objective] To explore the effectiveness of applying the PDCA (Plan-Do-Check-Act) cycle to enhance the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients across multiple hospital campuses. [Methods] Clinical blood transfusion data from May to July 2022 were selected. Specific improvement measures were formulated based on the survey results, and the PDCA cycle management model was implemented from August 2022. The post-intervention phase spanned from August 2022 to October 2023. The Rh phenotype compatibility rate, the detection rate of Rh system antibodies, and the proportion of Rh system antibodies among unexpected antibodies were compared between the pre-intervention phase (May to July 2022) and the post-intervention phase. [Results] After the continuous improvement with the PDCA cycle, the compatibility rate for the five Rh blood group antigen phenotypes between donors and recipients from August to October 2023 reached 81.90%, significantly higher than the 70.54% recorded during the pre-intervention phase (May to July 2022, P<0.01), and displayed a quarterly upward trend (β=0.028, P<0.05). The detection rate of Rh blood group system antibodies (β=-9.839×10^-5, P<0.05) and its proportion among all detected antibodies (β=-0.022, P<0.05) showed a quarterly decreasing trend, both demonstrating a negative correlation with the enhanced compatibility rate (r values of -0.981 and -0.911, respectively; P<0.05). [Conclusion] The implementation of targeted measures through the PDCA cycle can effectively increase the compatibility rate of five Rh blood group antigen phenotypes between donors and recipients, reduce the occurrence of unexpected Rh blood group antibodies, thereby lowering the risk of transfusion and enhancing the quality and safety of medical care.

OBJECTIVETo study the clinical effect of pidotimod oral liquid as adjuvant therapy for infectious mononucleosis and its effect on T lymphocyte subsets.

METHODSA total of 76 children with infectious mononucleosis, who were admitted to the hospital between July 2016 and June 2017, were enrolled and randomly divided into two groups: conventional treatment and pidotimod treatment (n=38 each). The children in the conventional treatment group were given antiviral therapy with ganciclovir for injection and symptomatic treatment. Those in the pidotimod treatment group were given pidotimod oral liquid in addition to the treatment in the conventional treatment group. The course of treatment was two weeks for both groups. The two groups were compared in terms of the recovery of clinical indices and the changes in peripheral blood T lymphocyte subsets.

RESULTSCompared with the conventional treatment group, the pidotimod treatment group had significantly shorter fever clearance time, time to the disappearance of isthmopyra, time to the relief of lymph node enlargement, time to the relief of hepatosplenomegaly, and length of hospital stay (P<0.05). After treatment, the pidotimod treatment group had significant reductions in the percentages of CD3 and CD8 T cells and had significantly lower percentages of CD3 and CD8 T cells than the conventional treatment group (P<0.001). The pidotimod treatment group had significant increases in the percentage of CD4 T cells and CD4/CD8 ratio after treatment, which was significantly higher than those in the conventional treatment group (P<0.001). The conventional treatment group had no significant changes in T lymphocyte subsets after treatment (P>0.05).

CONCLUSIONSPidotimod oral liquid has a good clinical effect as the adjuvant therapy for infectious mononucleosis and can improve cellular immune function, so it holds promise for clinical application.

OBJECTIVE: To investigate the role of IL-17A in promoting the activation of lung fibroblasts and the secretion of chemokine CXCL12, and to explore the possible mechanism. METHODS: Lung tissues of BALB/c mice were collected after intraperitoneal injection of recombinant mouse IL-17A (rmIL-17A). Real-time RT-PCR and Western blotting were used to detect the expression levels of α-smooth muscle actin (α-SMA) and collagen I in lung tissues, and immunohistochemical staining and real-time RT-PCR were used to determine the expression of CXCL12. Normal mouse primary lung fibroblasts were isolated and cultured, and identified by immunofluorescence staining with optical microscopy. Cells and supernatant of culture medium were collected after stimulation with rmIL-17A at different concentrations. mRNA levels of α-SMA, collagen I, and CXCL12 in the cells were determined by real-time RT-PCR, and the levels of collagen I and CXCL12 in the supernatant of culture medium were determined by ELISA. RESULTS: The mRNA and protein levels of α-SMA and collagen I in the lung tissue of mice injected with rmIL-17A were significantly increased compared with the control group (all CONCLUSIONS s: IL-17A can promote the activation of lung fibroblasts and translation into myofibroblast. The secretion of collagen is increased, which promote the deposition of extracullular matrix, and leads to the occurrence and development of lung fibrosis. CXCL12, a chemokine secreted by activated fibroblasts, may be involved in this process.

OBJECTIVE: To assess the value of genetic screening by high-throughput sequencing (HTS) for the early diagnosis of neonatal diseases. METHODS: A total of 2 060 neonates born at Ningbo Women and Children's Hospital from March to September 2021 were selected as the study subjects. All neonates had undergone conventional tandem mass spectrometry metabolite analysis and fluorescent immunoassay analysis. HTS was carried out to detect the definite pathogenic variant sites with high-frequency of 135 disease-related genes. Candidate variants were verified by Sanger sequencing or multiplex ligation-dependent probe amplification (MLPA). RESULTS: Among the 2 060 newborns, 31 were diagnosed with genetic diseases, 557 were found to be carriers, and 1 472 were negative. Among the 31 neonates, 5 had G6PD, 19 had hereditary non-syndromic deafness due to variants of GJB2, GJB3 and MT-RNR1 genes, 2 had PAH gene variants, 1 had GAA gene variants, 1 had SMN1 gene variants, 2 had MTTL1 gene variants, and 1 had GH1 gene variants. Clinically, 1 child had Spinal muscular atrophy (SMA), 1 had Glycogen storage disease II, 2 had congenital deafness, and 5 had G6PD deficiency. One mother was diagnosed with SMA. No patient was detected by conventional tandem mass spectrometry. Conventional fluorescence immunoassay had revealed 5 cases of G6PD deficiency (all positive by genetic screening) and 2 cases of hypothyroidism (identified as carriers). The most common variants identified in this region have involved DUOX2 (3.93%), ATP7B (2.48%), SLC26A4 (2.38%), GJB2 (2.33%), PAH (2.09%) and SLC22A5 genes (2.09%). CONCLUSION Neonatal genetic screening has a wide range of detection and high detection rate, which can significantly improve the efficacy of newborn screening when combined with conventional screening and facilitate secondary prevention for the affected children, diagnosis of family members and genetic counseling for the carriers.

OBJECTIVE To assess the association of copy number variations (CNVs) in chromosome 17q with the overall survival(OS) of patients with hepatocellular carcinoma(HCC), and to screen for target genes contained in the OS-related CNVs. METHODS A total of 174 HCC cases were enrolled. For 66 patients, the follow-up data was available. High-resolution Agilent Hu-244A array comparative genomic hybridization (aCGH) and Affymetrix U133 Plus 2.0 expression arrays were used to detect CNVs and gene expression of genes from the 17q region, respectively. The association of CNVs and OS was assessed with Log-rank test, Kaplan-Meier survival analysis, and Cox proportional hazards models. The gene expression in HCCs with 17q gain, HCCs without, and non-tumor liver tissues were compared with a Mann-Whitney U test. RESULTS Univariate association analysis showed that copy number gain in 17q25.1-25.3 was significantly associated with reduced OS (Log-rank test, P = 0.00002), and HCC cases with 17q25.1-25.3 gain had a 4.76-fold (95%CI: 2.31-9.81) increased hazard ratio (HR) for death from HCC, as compared to those without the gain. Multivariate Cox proportional hazards regression model revealed 17q25.1-25.3 gain to be an independent prognostic marker for poor OS (HR = 3.17, 95%CI: 1.39-7.26, P = 0.006). The expression levels of 18 genes in 17q25.1-25.3 including SLC9A3R1, GRB2, and TK1 were significantly increased in HCCs with gain than in those without (all P < 0.01) and non-tumor liver tissues (all P < 0.01). CONCLUSION The association of 17q25.1-25.3 gain with reduced OS has indicated that it is a prognostic marker for poor patient survival in HCC, for which SLC9A3R1, GRB2, and TK1 are candidate genes.
