Objective:To investigate the current status of hospitalized neonatal death of different gestational ages in Shaanxi Province.Methods:All neonatal deaths in six hospitals in Shaanxi Province from 2016 to 2020 were retrospectively analyzed, and the differences in perinatal complications, the causes of death, and the age at death were compared using Chi-square (or Fisher's exact ) test. Results:(1) Totally, 220 488 neonates were delivered in the obstetric department of the six hospitals during the study period; 71 782 out of them were admitted to the neonatal department. While 424 neonatal death was reported, giving the total hospitalized neonates mortality rate of 5.5‰ (394/71 782), which included 152 deaths of transferred patients ( n=9 103, 16.7‰), 226 premature (53.3%), 196 term (46.2%), and two post-term infants (0.5%). (2) Among mothers of dead neonates, 73.6% were found to have at least one perinatal complication. The most common one was fetal distress (146 cases, 34.4%), followed by gestational diabetes mellitus (113 cases, 26.7%), amniotic fluid abnormalities ( n=73, 17.2%), maternal infectious diseases ( n=71, 16.8%), and hypertensive disorders in pregnancy (HDP) ( n=52, 12.3%). The lower the gestational age, the higher the proportion of multiple pregnancies and assisted reproduction technology applied (Fisher exact test, P<0.05). On the contrary, the higher the gestational age, the higher the cesarean section rate ( χ 2=26.69, P<0.001). HDP was more likely to occur in the gestational age of 28-31 +6 and 32-34 +6 weeks ( χ 2=37.16, P<0.001), and amniotic fluid abnormalities were more likely to occur in those over 37 weeks ( χ 2=27.47, P<0.001). (3) The five leading causes of neonatal death were neonatal respiratory distress syndrome (NRDS, n=100, 23.6%), neonatal asphyxia ( n=88, 20.8%), maternal infectious diseases ( n=80, 18.9%), and birth defects ( n=54, 12.7%), and pulmonary hemorrhage ( n=22, 5.2%). The first three causes of death in term and post-term infants were neonatal asphyxia ( n=65, 32.8%), birth defects ( n=42, 21.2%), and infectious diseases ( n=26, 13.1%). NRDS ( n=83, 36.7%), infectious diseases ( n=54, 23.9%), and neonatal asphyxia ( n=23, 10.2%) were the three leading causes of death of premature babies. (4) Out of the 326 (76.9%) neonatal deaths within seven days after birth, 162 (38.2%) died within 24 h after birth and 164 cases (38.7%) between one to seven days after birth. Conclusions:Most neonatal deaths occurred among preterm ones and within seven days after birth, whose mothers suffered perinatal complications. The causes of neonatal death vary among different gestational age groups.

Objective To monitor the quality of intravenous infusions in a constructed closed-loop tracking system,and to discuss its application effect.Methods The information program is reinvested in a team for the closed-loop tracking system of the intravenous infusion.There are modules of processing medical orders,pharmacy preparations,execution procedures with the doctor's orders,as well as the computing module.The system was put into clinical trial operation in November 2021 and officially applied in January 2022.Specifically,the number of infusion-related adverse events/red-light alert is recorded and compared before(January to December 2021)and after(January to December 2022)the application of the system.Random sampling method has been performed in a ward to investigate the amount of abnormal infusion for the comparison.Results It is shown that it occurred 3 times for the infusion-related adverse events before the operation of the system,and a time after that.In the neurological inpatients,we observe the amount of red-light alert as 5,120.25±775.82 before the system operation,and 1,518.25±74.77 after that.It is shown to decline by 70.35％on average with statistical significance on the total difference(P＜0.001).Monthly amount of infusion in the ward is 5,184 with 155 times of overfast(2.99％)for 775 minutes in total,and with 207 times of slow(3.99％)for 1,035 minutes in total.The average handling time per contact is 5 minutes.Conclusion The closed-loop tracking system for intravenous infusion quality monitoring can track and record the whole process of intravenous infusions.It is expected to provide accurate and objective data for closed-loop quality inspection on clinical nursing practice,which is conducive to nursing managers for any potential problems during infusion processing timely,to promote standardized nursing operations,and to further improve the safety of inpatients with intravenous infusion and medication.

Objective: To conduct a systematic review and meta-analysis of studies evaluating the oncological and fertility outcomes of early-stage endometrial cancer (EC) treated with the levonorgestrel-releasing intrauterine system (LIUS)-based regimens. Methods: The Meta-analyses Of Observational Studies in Epidemiology statement for meta-analyses was followed. Searches were conducted on MEDLINE, Embase, PubMed, Preprints, and the Cochrane Central Register of Controlled Trials from January 1990 to August 4, 2022. The Joanna Briggs Institute Critical Appraisal Checklist was used for quality assessment. The primary endpoint was the complete response (CR) rate and the secondary endpoints were relapse, pregnancy, and live birth rate. Results: A total of 25 studies (821 women) were included. The CR rate of LIUS-based regimens was 63.4% (95% confidence interval [CI]=52.3%–73.2%), with 29.6% (95% CI=23.3%–36.8%) of cases experiencing recurrence during follow-up. In sensitivity analyses, patients younger than 45 years of age with a body mass index <30 kg/m2 who were treated with LIUS-based regimens achieved a high CR rate of 84.6% (95% CI=80.3%–88.1%) over a median follow-up of more than 24 months. Overall pregnancy and live birth rates were 37.9% (95% CI=24.1%–53.9%) and 39.3% (95% CI=24.0%–57.0%), respectively. No statistical differences were apparent in CR or relapse rates among the LIUS+GnRH agonist, LIUS+oral progesterone, or hysteroscopic resection followed by LIUS subgroups. Conclusion LIUS-based therapies are viable for the conservative management of early-stage endometrioid EC on CR and fertility outcome.

Objective:To determine the alteration of miRNA profile of human tonsillar epithelial cells induced by enterovirus-A71 (EV-A71) infection.Methods:Human tonsillar epithelial cells UT-SCC-60B were infected with EV-A71 at multiplicities of infection (MOI) of 1 and total RNA was extracted using Trizol reagent. Small RNA library was constructed and high-throughput sequencing was performed using Illumina NextSeq 500. Differential significantly expressed known and novel miRNAs and putative targets were selected after the processing of raw data. Gene ontology (GO), kyoto encyclopedia of genes and genomes (KEGG) pathways were analyzed through online database. Kinds of miRNA could target EV-A71 genome was determined through psRNATarget. Validations of random selected miRNAs were done through real-time RT-PCR.Results:A total of 61 known significantly expressed miRNAs (21 miRNAs were down-regulated and 40 miRNAs were up-regulated) and 559 novel significantly expressed miRNAs were identified through high-throughput sequencing. Novel significantly expressed miRNA had typical "hairpin structure" of pre-miRNA. Fold changes of hsa-miR-517b-3p and hsa-miR-199a-5p which was determined by real-time RT-PCR had similar change trends with high-throughput sequencing. Putative targets of significantly expressed miRNA were referred to different biological processes and signaling pathways. A total of 24 significant miRNAs (5 known significantly expressed miRNAs and 19 novel significantly expressed miRNAs) had "seed sequence" in EV-A71 genome.Conclusions:Expression of miRNA profile in UT-SCC-60B was significantly changed by EV-A71 infection and the identified significantly expressed miRNAs potential target EV-A71 genome to regulate EV-A71 replication.

Objective:To observe the effect of conversion from immediate-release tacrolimus (Tac) to extended-release Tac on kidney function in stable kidney transplant recipients.Methods:83 stable kidney transplant recipients who were converted from immediate-release Tac to extended-release Tac in the second people's hospital of Shanxi province from December 2011 to June 2019 were followed up for 12-36 months, and 83 stable kidney transplant recipients who continued to take immediate-release Tac were selected as control group.The changes of kidney function indexes, Tac trough concentration intra-patient variability (IPV) and compliance, the incidence of rejection and the survival rate of grafts and recipients were observed after the conversion from immediate-release Tac to extended-release Tac in stable kidney transplant recipients.Results:The conversion time from immediate-release Tac to extended-release Tac was (42.76±30.50)months after transplantation. At 24 months after conversion, the serum creatinine (SCr) was significantly lower than that before conversion ( P=0.013), and the estimated glomerular filtration rate(eGFR)was significantly higher than that before conversion( P=0.005). In the experimental group , the SCr was significantly lower than that of the control group at 36 months after conversion ( P= 0.017), eGFR was significantly higher than that of the control group ( P=0.038). In the experimental group, the score of Immunosuppressant Therapy Barrier Scale (ITBS) was (20.23±2.89) before conversion and (17.63 ±3.08) after conversion ( P= 0.000). The daily dose of Tac was (2.09 ±0.84) mg before conversion and (2.10 ±0.83) mg after conversion. The trough concentration of Tac before conversion was (7.22 ±2.84) ng/mL, which reduced significantly after conversion. No rejection occurred after conversion, and the recipients/grafts survived healthily during the follow-up period. Conclusions:After conversion from immediate-release Tac to extended-release Tac in stable kidney transplant recipients, the kidney function is stable and better than that of before conversion, the compliance is significantly improved, the IPV of Tac trough concentration is significantly reduced, and long-term use of extended-release Tac has good clinical efficacy and safety.

Objective To evaluate the effect of multi-disciplinary team (MDT) on acute heart failure (AHF) complicated with respiratory failure after allograft nephrectomy. Methods MDT discussion was performed on a patient with hemorrhagic shock caused by sudden renal graft hemorrhage, who developed acute myocardial infarction (AMI) with AHF, acute pulmonary congestion, pulmonary infection and acute respiratory failure 2 weeks after allograft nephrectomy. And treatment plan was formulated and effect evaluation was conducted. Results Based on the opinions of MDT discussion, the patient was given nasal high-flow oxygen therapy, continuous veno-venous hemodiafiltration (CVVHDF) to reduce cardiac load, anticoagulant, dilating blood vessels, reducing myocardial oxygen consumption, improving myocardial remodeling, lipid regulation, anti-infection, nutritional support, and other comprehensive treatment. The clinical outcome of the patient was good and regular hemodialysis treatment was resumed. Conclusions Application of MDT pattern helps to formulate a comprehensive and effective individualized treatment plan for patients with AHF and respiratory failure after allograft nephrectomy, which can enhance clinical treatment effects and improve prognosis of patient.

Objective:To investigate the correlation between gamma-glutamyl transferase/high-density lipoprotein cholesterol ratio (GHR), neutrophil/lymphocyte ratio (NLR) and coronary heart disease (CHD), and evaluated its pathogenic risk and predictive value for CHD.Methods:A total of 694 patients admitted to our hospital from December 2017 to December 2018 for suspected CHD and coronary angiography were selected. According to the results of coronary angiography,the patients were divided into CHD group ( n=527) and non-CHD group ( n=167). The clinical data of all patients were recorded. Gamma-glutamyl transferase (GGT), high-density lipoprotein cholesterol (HDL-C) and other biochemical indicators were recorded. Neutrophils, lymphocyte count and other hematological indicators were recorded. GHR, NLR and Gensini scores of the patients were calculated. Clinical data and GHR, NLR and other indicators were compared between the two groups. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of GHR, NLR in CHD, and to determine the optimal cut-off value; Logstic regression analysis was used to investigate the risk factors of CHD.Spearman correlation analysis was used to analyze the correlation between serum OPN, OPG and Gensini score in patients with CHD. Results:The GHR and NLR were 32.59(21.05, 48.24) and 3.53(2.18, 8.46) significantly higher in the CHD group than in the non-CHD group 16.56(10.07, 25.21) and 2.20(1.45, 3.28) respectively, with statistically significant differences ( Z=11.094, 9.055, P<0.05). ROC curve analysis showed that the AUC of NLR and MLR in diagnosing CHD was 0.785 and 0.732( P<0.05). When the critical values of GHR and NLR respectively were 19.805 and 2.678, respectively, the diagnostic efficiency of CHD was the highest, and the sensitivity and specificity were 79.30%, 62.90% and 63.80%, 68.30%, and the AUC of GGT in diagnosing CHD was 0.628. When the critical value was 19.500, the sensitivity and specificity were 80.50% and 39.50%, respectively,the AUC of GHR was greater than that of GGT ( Z=12.973, P<0.05). Multivariate Logistic regression analysis showed that Smoking ( OR=2.887, 95% CI:1.850-4.505, P<0.05), hypertension ( OR=2.009, 95% CI: 1.311-3.080, P<0.05), fasting plasma glucose ( OR=1.109, 95% CI:1.034-1.189, P<0.05), age ≥60 years ( OR=1.567, 95% CI:1.179-2.415, P<0.05), NLR ≥2.687 ( OR=3.152, 95% CI:2.066-4.808, P<0.05) and GHR ≥19.805 ( OR=4.768, 95% CI:3.131-7.262, P<0.05) was an independent risk factor for CHD. After gradually adjustment for risk factors such as smoking, hypertensive, fasting plasma glucose, age ≥60 years and NLR ≥2.687, GHR ≥19.805 was still an independent risk factor for coronary heart disease(OR and 95% CI were 4.620 (3.049-7.000), 4.768 (3.131-7.262), 6.567 (4.408-9.810), 4.768 (3.131-7.262), 4.768 (3.131-7.262), respectively; all P<0.001). Spearman correlation analysis showed that GHR and NLR were positively correlated with Gensini score ( r=0.312, 0.394; all P<0.05). Conclusion:GHR and NLR were positively correlated with the severity of coronary artery disease, which is of significance in the diagnosis of coronary heart disease. NLR ≥2.687 and GHR ≥19.805 were independent risk factors for CHD. GHR was superior to GGT and HDL-C alone in the diagnosis of CHD,and has certain clinical application value

Objective:To analyze the complications and outcomes during the hospitalization of extremely premature infants (EPI) and extremely low birth weight infants (ELBWI).Methods:Clinical data of 168 cases of EPI and ELBWI admitted to 4 hospitals of grade three in Shaanxi Province between January 1, 2015 and December 31, 2017 were retrospectively analyzed.The information of general data, prenatal care, complications and outcomes were summarized.Outcomes of different groups were compared according to birth weight and gestational age.Results:A total of 168 cases of EPI and ELBWI were collected.The rate of delivery in tertiary hospitals was 86.9% (146/165 cases), 86 patients (57.7%) received prenatal Dexamethasone.The mean gestational age was (27.9±1.7) weeks, and the mean birth weight was (951.6±148.9) g. The highest rates of pregnancy complications included gestational hypertension (44/149 cases, 29.5%), premature rupture of membranes (43/149 cases, 28.9%) and gestational diabetes (16/149 cases, 10.7%). The first three neonatal complications were neonatal respiratory distress syndrome (16/168 cases, 95.2%), bronchopulmonary dysplasia (73/110 cases, 66.4%) and retinopathy of prematurity (65/110 cases, 59.1%). The survival rate of EP and ELBWI in 168 cases was 61.9% (104/168 cases), the abandonment rate was 27.4% (46/168 cases), and the mortality in hospital was 10.7% (18/168 cases). According to birth weight and gestational age, there were no statistically significant differences in survival, abandonment and hospital mortality among different birth weight groups( χ2=4.361, 5.104, 1.630, all P>0.05), while there were statistically significant differences in survival, abandonment and hospital mortality among different gestational age groups( χ2=21.650, 8.164, 13.490, all P<0.05). Conclusions:There are many complications of EPI and ELBWI and the outcomes are closely related to the gestational age of birth.Improving the perinatal management level and the professional diagnosis and treatment level of neonatology are helpful to improve the survival rate and prognosis.

Objective: To investigate the epidemiological data of nosocomial sepsis of premature infants with gestational age less than 34 weeks and the distribution characteristics of pathogenic bacteria in Shaanxi province. Methods: A retrospective analysis of clinical data of premature infants born with gestational age < 34 weeks born between January 1 and December 30, 2018 in Neonatal Intensive Care Units(NICU) in 4 Grade A Class Three hospitals in Shaanxi province was performed.The high risk factors and pathogenic bacteria were analyzed by using chi-square test and t test for statistical analysis. Results: Totally 823 infants were included in this study, among whom, 73 patients developed nosocomial sepsis, and the incidence was 8.9%.The mean gestational age of the 73 patients with nosocomial sepsis was (30.6±2.2) weeks and mean birth weight was (1 320.3±450.5) g. The rate of invasive ventilator was 23.4%(52/222 cases). The rate of peripherally inserted central catheter (PICC) was 20.1% (61/303 cases). The rate of early antibiotic use was 8.1% (39/481 cases) and breast feeding rate was 9.3% (63/675 cases). The rate of PICC and ventilator use were statistically different between the non-infection group and the infection group(all P<0.05). There were 31 strains of pathogenic bacteria, among which gram-negative bacilli was the most common (22 strains, 70.9%), which mainly were klebsiella pneumoniae strains (15 strains, 48.4%), and 6 strains(19.4%) of Fungus was detected. Conclusions The incidence of nosocomial sepsis in NICU in Shaanxi province is higher, gram-negative bacilli was the most common pathogenic bacteria, among which, klebsiella pneumoniae was main, it is necessary to strengthen the regular monitoring and analysis of nosocomial infection in NICU in order to reduce the incidence of nosocomial infection and sepsis.
