Objective: To compare the effectiveness of less invasive surfactant administration (LISA) and intubate surfactant extubation (INSURE) on respiratory distress syndrome (RDS) among premature infant, so as to provide insights into improving treatment effects and reducing complications of RDS among premature infants. Methods: A total of 71 premature infants with RDS in Anhui Provincial Maternity and Child Health Hospital were randomly assigned into the LISA and INSURE group, and pulmonary surfactant (PS) administration was carried out by LISA and INSURE with basic support therapy and respiratory support therapy. The general information, arterial blood gas analysis before and after treatment, respiratory support time and incidence of complications were collected and compared between the two groups. Results: There were 31 cases in the LISA group, with a gestational age of (29.81±0.99) weeks and 22 male cases, and 40 cases in the INSURE group, with a gestational age of (30.02±1.13) weeks and 26 male cases. There were no significant differences in basic characteristics (including gestational age, birth weight, gender, etc.) between the two groups (all P>0.05). After administration, the level of PaO2 was lower in the LISA group than in the INSURE group [(78.35±6.55) mmHg vs. (87.68±8.21) mmHg, P<0.05], the level of PaCO2 was higher in the LISA group than in the INSURE group [(43.03±6.34) mmHg vs. (38.68±9.69) mmHg, P<0.05], and the incidence of bronchopulmonary dysplasia was lower in the LISA group than in the INSURE group (48.39% vs. 72.50%, P<0.05). Linear regression analysis showed that with the duration of LISA administration increase (2-7 min), the minimum heart rate of premature infants increased linearly (β=13, P<0.05). Conclusions Compared with INSURE, LISA administration could slowly improve ventilation oxygenation, reduce hyperventilation and incidence of bronchopulmonary dysplasia among premature infants with RDS. The incidence of slow heart rate may be reduced by appropriately prolonging the administration duration.

Hepatitis C virus (HCV) infects more than 200 million people globally and its increasing incidence is placing a heavy economic burden on resource-poor countries.Effective HCV diagnosis is of guiding significance for treatment selection and monitoring.Techniques for detection of HCV infection include serological and nucleic acid detection.Serological assay is simple and easy to operate for initial HCV diagnosis.However,the window phase is long,so the active phase of the virus or previous infection cannot be determined.Nucleic acid detection has high sensitivity and wide linear range,which is the direct evidence to determine virus infection.The traditional thermal cycle-based nucleic acid amplification technology has been widely used in clinical laboratories.The development of isothermal nucleic acid amplification technology overcomes the limitations of traditional amplification technology,and it can be used as a tool for Point-of-care Testing (POCT),which has great potential and particularly suitable to be used in low-resource areas with high HCV prevalence,such as Africa and Southeast Asia.In this paper,we outline the current advance and development trends in the HCV molecular diagnosis.

Objective:To investigate the current status of primiparas′ postpartum fatigue and paternal involvement, and to explore the relationship between primiparas′ postpartum fatigue and paternal involvement, and to provide reference basis for developing targeted intervention measures to alleviate postpartum fatigue of primiparas.Methods:A cross-sectional survey was conducted on 347 primiparas from Affiliated Hospital of Yangzhou University, Yangzhou Maternal and Child Health Care Hospital from September to December 2020 by convenience sampling. The survey instruments included the general information questionnaire, the Parenting Alliance Inventory (PAI), and the Postpartum Fatigue Scale (PFS).Results:The total score of PAI was (86.51 ± 12.07) points, and the level of paternal involvement was high. The total score of PFS was (16.68 ± 4.12) points. 95.97% (333/347) of primiparas had varying degrees of postpartum fatigue. There was a significant negative correlation between paternal involvement and primiparas′ postpartum fatigue ( r=-0.327, P<0.01). The results of multiple stratified regression analysis showed that paternal involvement was included in the influencing factor model of primiparas′ postpartum fatigue, which could independently explain 9.7% variation of primiparas′ postpartum fatigue. Conclusions:The higher level of paternal involvement could predict the lower level of primiparas′ postpartum fatigue. Medical staff should pay attention to the participation level of the spouses of primiparas in childcare, and improve the participation level of the spouses of primiparas in scientific ways to alleviate the postpartum fatigue of primiparas.

Objective:To evaluate the efficacy of remimazolam combined with low-dose propofol for sedation during induction of anesthesia.Methods:A total of 228 patients of both sexes, aged 18-64 yr, with body mass index of 19-35 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy, were divided into 2 groups ( n=114 each) by a random number table method: remimazolam combined with low-dose propofol group (group R) and propofol group (group P). Anesthesia was induced with intravenous injection of sufentanil 0.3 μg/kg, remimazolam 0.3 mg/kg, propofol 0.5 mg/kg and micuronium 0.2 mg/kg in group R, and sufentanil 0.3 μg/kg, propofol 2 mg/kg and micuronium 0.2 mg/kg in group P. Endotracheal intubation was performed when bispectral index value ≤ 50.Before induction (T 0), immediately before intubation (T 1), at 1 min (T 2) and 3 min (T 3) after intubation, mean arterial pressure (MAP) and heart rate (HR) were recorded.The anesthesia induction time and the incidence of hypotension and bradycardia were recorded in the two groups. Results:There was no significant difference in MAP and HR at T 0 between the two groups ( P>0.05). Compared with the value at T 0, MAP in two groups and HR were significantly decreased at T 1-3 in group P ( P<0.01). Compared with group P, the anesthesia induction time was significantly prolonged, and hypotension and bradycardia was decreased in group R ( P<0.05). Conclusion:The combination of remimazolam and low-dose propofol exerts better efficacy for sedation during induction of anesthesia than propofol alone.

Objective:To evaluate the efficay of different doses of remimazolam for anesthesia induction during reoperation in asthenic patients with tracheotomy.Methods:One hundred and twenty patients of both sexes, aged 19-64 yr, with a modified frailty index score ≥3, of American Society of Anesthesiologists physical status Ⅳ, scheduled for reoperation after tracheotomy, were divided into 4 groups ( n=30 each)using a random number table method: propofol group (group C) and different doses of remimazolam groups (R 1, R 2 and R 3 groups). Anesthesia was induced with intravenous sufentanil 5 μg, propofol 1.5 mg/kg in group C and with remimazolam 0.1, 0.2 and 0.3 mg/kg in R 1, R 2 and R 3 groups, respectively.The tracheotomy cannula was replaced with a reinforced endotracheal intubation (ID=6.0 mm) when bispectral index value ≤ 65.Mean arterial pressure and heart rate were recorded before induction (T 0), immediately before replacement of the tube (T 1) and immediately after replacement of the tube (T 2). The onset time of anesthesia and adverse reactions such as hypotension, bradycardia and bucking during replacement of the tube, and requirement for rescue sedation were recorded. Results:Compared with group C, mean arterial pressure was significantly increased at T 1, 2 in group R 1 and group R 2, the onset time of anesthesia was significantly prolonged, the incidence of hypotension and bradycardia was decreased in R 1, R 2 and R 3 groups, and the requirement for rescue sedation in group R 1 and incidence of bucking in group R 1 and group R 2 were increased ( P<0.05 or 0.01). Compared with group R 1, heart rate at T 2 was significantly decreased, the onset time of anesthesia was shortened, and the requirement for rescue sedation and incidence of bucking were decreased in C, R 2 and R 3 groups, and the incidence of hypotension was significantly increased in group R 3 ( P<0.05 or 0.01). Compared with group R 2, the onset time of anesthesia was significantly shortened in group R 3 ( P<0.05). Conclusions:Remimazolam 0.2 mg/kg provides good efficacy when used for anesthesia induction with fewer side effects during reoperation in asthenic patients with tracheotomy.

Objective To investigate the application value of tenofovir alafenamide fumarate(TAF)in patients with first-time hepatitis B virus-related decompensated cirrhosis(HBV-DC)and its impact on renal function and lipid metabolism.Methods A total of 57 patients with first-time HBV-DC who were hospitalized and received TAF antiviral therapy in The Affiliated Hospital of Xuzhou Medical University from January 1,2020 to December 31,2022 were enrolled,and all of them received TAF antiviral therapy.Related data were collected at baseline and at weeks 12,24,and 48 of treatment,including virological and serological indicators,liver and renal function,serum phosphorus,and blood lipids.The paired t-test or single group repeated measures ANOVA were used for comparison of normally distributed continuous data,the Friedman test was used for comparison of non-normally distributed continuous data,and the chi-square test or the Fisher's exact test were used for categorical data.Results A total of 52 patients completed the 48 weeks of follow-up.After 12,24,and 48 weeks of treatment,the patients achieving HBV DNA seroconversion accounted for 38.5%,63.5%,and 84.6%,respectively;the alanine aminotransferase normalization rate were 71.2%,82.7%,and 82.7%,respectively;the proportion of the patients with Child-Pugh class A disease increased to 55.8%,73.1%,and 92.3%,respectively.Within the 48 weeks of treatment,there were significant increases in the levels of cystatin C(χ2=35.163,P＜0.001)and serum phosphorus(F=8.600,P＜0.001)and low-density lipoprotein cholesterol(χ2=10.064,P=0.018).The ratio of total cholesterol/high-density lipoprotein cholesterol decreased continuously from 3.61(2.61～5.84)to 3.27(2.70～4.36)(χ2=5.000,P=0.172).Conclusion TAF can rapidly inhibit HBV replication and significantly improve liver function in HBV-DC patients,with no significant impact on renal function.However,blood lipid should be closely monitored.

Background: and Purpose This study aimed to investigate the association between residual inflammatory risk (RIR) and vulnerable plaques using high-resolution magnetic resonance imaging (HRMRI) in symptomatic intracranial atherosclerotic stenosis (ICAS). Methods: This retrospective study included 70%–99% symptomatic ICAS patients hospitalized from January 2016 to December 2022. Patients were classified into four groups based on high-sensitivity C-reactive protein (hs-CRP) and low-density lipoprotein cholesterol (LDL-C): residual cholesterol inflammatory risk (RCIR, hs-CRP ≥3 mg/L and LDL-C ≥2.6 mmol/L), RIR (hs-CRP ≥3 mg/L and LDL-C <2.6 mmol/L), residual cholesterol risk (RCR, hs-CRP <3 mg/L and LDL-C ≥2.6 mmol/L), and no residual risk (NRR, hs-CRP <3 mg/L and LDL-C <2.6 mmol/L). Vulnerable plaque features on HRMRI included positive remodeling, diffuse distribution, intraplaque hemorrhage, and strong enhancement. Results: Among 336 included patients, 21, 60, 58, and 197 were assigned to the RCIR, RIR, RCR, and NRR groups, respectively. Patients with RCIR (adjusted odds ratio [aOR], 3.606; 95% confidence interval [CI], 1.346–9.662; P=0.011) and RIR (aOR, 3.361; 95% CI, 1.774–6.368, P<0.001) had higher risks of strong enhancement than those with NRR. Additionally, patients with RCIR (aOR, 2.965; 95% CI, 1.060–8.297; P=0.038) were more likely to have intraplaque hemorrhage compared with those with NRR. In the sensitivity analysis, RCR (aOR, 2.595; 95% CI, 1.201–5.608; P=0.015) exhibited an additional correlation with an increased risk of intraplaque hemorrhage. Conclusion In patients with symptomatic ICAS, RIR is associated with a higher risk of intraplaque hemorrhage and strong enhancement, indicating an increased vulnerability to atherosclerotic plaques.

Objective To Analyze the expression profiles of LncRNAs and mRNAs in ovarian epithelial cancer cell lines by gene mi-croarray, and then provide experimental evidences for investigating the function of LncRNAs associated with ovarian cancer. Methods The differentially expressed LncRNAs and mRNAs in ovarian epithelial cancer cell lines, such as A2780, HO8910 and SKOV3, and ovarian epithelial cell line HOSEpiC were analyzed by gene microarray. The differentially expressed mRNAs were further performed the KEGG pathway enrichment analysis. The expression levels of six candidate LncRNAs, which had significant difference between the o-varian epithelial cancer cell line and the ovarian epithelial cell line, were further verified by qRT-PCR. Results There were 227 up-regulated LncRNAs and 483 down-regulated LncRNAs in A2780, HO8910 and SKOV3 cell lines. The differentially expressed mRNAs in A2780, HO8910 and SKOV3 cell lines were mainly enriched in the tumor-related pathways such as PI3K-AKT, mTOR and TNF-α( P<0.05) . The expression levels of PTPRG-AS1, CCNT2-AS1, XLOC 009869 and LINC01138 in ovarian epithelial cancer A2780, SKOV3 and OVCR3 cell lines were up-regulated (P<0.05), while those of RP11-252P19.2 and RP11-744I24.2 in ovarian epithelial cancer A2780, SKOV3, OVCR3 and 3AO cell lines were down-regulated ( P<0.05) . Conclusion The differentially expressed LncR-NAs and mRNAs in ovarian epithelial cancer cell lines may be obtained by gene microarray, and the differentially expressed mRNAs are associated with the tumor-related pathways such as PI3K-AKT, mTOR and TNF-α, which may provide new targets for the diagnosis and treatment of ovarian cancer.
