Objective:To explore the effect of communication competence and psychological resilience on job burnout among Operating Room nurses.Methods:From March to June 2023, randomized clustering sampling was used to select 138 registered Operating Room nurses from four ClassⅢ Grade A hospitals in Taizhou for investigation. The survey was conducted using the general information questionnaire, Operating Room Nurses' Job Stressor Scale, Chinese version of the Connor-Davidson Resilience Scale, Nurses' Clinic Communication Competence Scale, and Maslach Burnout Inventory-General Survey. Hierarchical linear regression analysis was used to explore the effects of communication competence and psychological resilience on job burnout among Operating Room nurses.Results:A total of 138 questionnaires were sent out, and 133 valid questionnaires were collected, with a valid response rate of 96.38% (133/138). Among 133 Operating Room nurses, the job burnout score was (56.35±9.28), and the communication competence, psychological resilience, and work stress scale scores were (196.71±18.92), (78.09±18.31), and (96.37±22.47), respectively. Pearson correlation showed that job burnout among Operating Room nurses was negatively correlated with psychological resilience ( r=-0.475, P<0.01) and communication competence ( r=-0.241, P<0.01), and positively correlated with work stress ( r=0.360, P<0.01). Hierarchical linear regression analysis showed that, after controlling for other variables, psychological resilience and communication competence were the influencing factors of job burnout among Operating Room nurses ( P<0.01), which could explain 17.70% of the variation. Conclusions:The level of job burnout among Operating Room nurses is relatively high, and psychological resilience and communication competence are independent influencing factors. Managers can provide psychological counseling and support services for Operating Room nurses, offer communication competence training programs, and prevent and reduce job burnout among Operating Room nurses.

Objective:To investigate the significance of N-terminal pro-brain natriuretic peptide (NT-proBNP) in the early assessment of neonatal cardiac dysfunction in sepsis.Methods:The children diagnosed with neonatal sepsis and common infection neonates admitted to the department of pediatric neonatal intensive care unit (NICU) of Liaocheng People's Hospital from January 2016 to January 2019 were enrolled. Data of clinical sign, laboratory results, bedside echocardiography and survival data were collected, and the differences of clinical indexes were compared among sepsis patients with and without cardiac dysfunction and common infection. The risk factors of sepsis with cardiac dysfunction were analyzed by multivariate Logistic regression, and the early prediction value of NT-proBNP for neonatal septic cardiac dysfunction was evaluated by the receiver operating characteristic (ROC) curve.Results:There were 112 neonates with sepsis (49 with cardiac dysfunction and 63 without cardiac dysfunction) and 67 children with common infection included in the analysis. The onset time of neonates in septic cardiac dysfunction group was significantly earlier than that of septic non-cardiac dysfunction group and common infection group [hours: 52.9 (0, 180.3) vs. 53.9 (0, 183.6), 81.0 (45.6, 202.4), both P < 0.05]. Compared with the general infection group, albumin (ALB), white blood cell count (WBC), left ventricular ejection fraction (LVEF) in septic cardiac dysfunction group significantly decreased, NT-proBNP, hypersensitive C-reactive protein (hs-CRP)/ALB, pulmonary artery systolic pressure (PASP) significantly increased, while right ventricular (RV) and Tei index significantly increased [ALB (g/L): 24.1±3.8 vs. 27.8±3.6, WBC (×10 9/L): 12.7 (3.7, 18.9) vs. 15.4 (9.9, 23.2), LVEF: 0.626±0.123 vs. 0.700±0.021, NT-proBNP (ng/L): 20 230.6 (15 890.0, 35 000.0) vs. 7 324.5 (2 426.5, 13 890.0), hs-CRP/ALB: 0.33 (0.29, 0.81) vs. 0.06 (0.00, 0.21), PASP (mmHg, 1 mmHg = 0.133 kPa): 52.25±14.12 vs. 41.07±27.73, RV (mm): 10.74±2.42 vs. 8.55±1.41, Tei index: 0.52±0.03 vs. 0.30±0.04, all P < 0.05]. NT-proBNP and Tei index in septic cardiac dysfunction group were significantly higher than those in septic non-cardiac dysfunction group [NT-proBNP (ng/L): 20 230.6 (15 890.0, 35 000.0) vs. 13 057.6 (8 946.0, 35 000.0), Tei index: 0.52±0.03 vs. 0.39±0.02, both P < 0.05], and LVEF was significantly lower than that in septic non-cardiac dysfunction group (0.626±0.123 vs. 0.671±0.086, P < 0.05). Multivariate Logistic regression analysis showed that NT-proBNP, Tei index and hs-CRP/ALB were independent risk factors for cardiac dysfunction in sepsis neonates [odds ratio ( OR) and 95% confidence interval (95% CI) were 8.73 (1.54-5.67), 1.97 (1.26-2.87), 1.87 (1.03-3.40) respectively, all P < 0.05]. ROC curve analysis showed that NT-proBNP, Tei index and hs-CRP/ALB had good predictive value for the occurrence of cardiac dysfunction in septic neonates, the area under ROC curve (AUC) was 0.81 (95% CI was 0.84-0.91), 0.78 (95% CI was 0.65-0.79) and 0.77 (95% CI was 0.61-0.77), respectively. The sensitivity and specificity of NT-proBNP were 80.0% and 79.0% respectively with 12 291.5 ng/L as the cut-off value, the sensitivity and specificity of Tei index were 74.0% and 77.0% respectively with 0.45 as the cut-off value, and the sensitivity and specificity of hs-CRP/ALB were 76.0% and 76.3% respectively with 0.10 as the cut-off value. Conclusions:NT-proBNP can be used as a diagnostic marker of early cardiac dysfunction, and for rapid diagnosis of neonatal cardiac dysfunction in sepsis. The application may guide clinicians to use drugs better to improve cardiac function and treatment effect.

Objective:To investigate the value of N-terminal pro-brain natriuretic peptide (NT-proBNP) combined with bedside echocardiography in diagnosis and treatment of neonatal sepsis with cardiac dysfunction.Methods:A total of 56 children diagnosed with neonatal sepsis in the Neonatal Intensive Care Unit, Liaocheng People′s Hospital from July 2016 to July 2017 were enrolled and divided into 2 groups, namely, the cardiac dysfunction group (26 cases) and the non-cardiac dysfunction group (30 cases). Children with general infection (45 cases) hospita-lized at the same period were taken as the control group.The clinical characteristics, related laboratory indexes and prognosis were compared among 3 groups.The related factors of neonatal sepsis with cardiac dysfunction were analyzed by the multivariate Logistic regression approach, and the value of related indexes in the early prediction neonatal sepsis with cardiac dysfunction was analyzed by using the receiver operating characteristic curve (ROC). Results:The onset age of sepsis patients with cardiac dysfunction [63.0 h (30.5 h, 185.6 h)] was significantly earlier than that of the patients without cardiac dysfunction [65.0 h (34.5 h, 170.6 h)] and the control group [80.0 h (45.5 h, 202.3 h)] ( P<0.05). The main primary site of the disease was the lung, which was not statistically significant among the 3 groups ( P>0.05). The NT-proBNP level and the high sensitivity-C-reactive protein (hs-CRP)/albumin (ALB) ratio in the cardiac dysfunction group [20 230.6 ng/L (15 890.0 ng/L, 35 000.0 ng/L); 0.33(0.29, 0.81)] were significantly higher than those in the control group [7 324.5 ng/L (2 426.5ng/L, 13 890.0 ng/L); 0.06(0, 0.21)] (all P<0.05). The right ventricular diameter and the Tei index of the cardiac dysfunction group [(8.74±2.42) mm; 0.52±0.03] were significantly higher than those in the control group [(8.55±1.41)mm; 0.30±0.04], while the EF of the cardiac dysfunction group [(62.61±2.56)%] was significantly lower than that in the control group [(70.03±0.35)%] (all P<0.05). The ROC curve analysis showed that NT-proBNP and the Tei index could effectively predict sepsis with cardiac dysfunction.Specifically, NT-proBNP had a cutoff value of 12 291.5 ng/L, with sensitivity of 80%, specificity of 79%, and the area under ROC curve (AUC) of 0.81.The Tei index had a cutoff value of 0.45, with sensitivity of 74%, specificity of 77%, and the AUC of 0.78. Conclusions:NT-proBNP can be used as a marker of early cardiac dysfunction.Its combination with the Tei index of bedside echocardiography can quickly diagnose cardiac dysfunction of children with sepsis, better guide clinicians in drug use, improve cardiac function of patients and enhance the treatment effect.

Objective To study the clinical features,diagnosis,treatment and prognosis of neonatal fulminant myocarditis.Method From January 2016 to August 2016,clinical data of neonates with fulminant myocarditis admitted to the neonatal intense care unit (NICU) were retrospectively collected and analyzed.Result A total of 11 neonates were enrolled,including 6 males and 5 females,and 5 preterms and 6 full term infants.The average gestation age was (37.7 ± 1.6) weeks and their weight on hospital admission was (3 382 ± 675) g.Among the infants,9 got ill in summer and 2 in spring and winter.The onset of illness was within 3 ～ 5 d after birth in 8 cases and 2 ～ 3 weeks in the other 3 cases.The main clinical presentations included fever,anorexia,shortness of breath and lethargy.Various degrees of cardiac dysfunction appeared in all 11 cases,including cardiogenic shock in 10 cases,severe arrhythmias with multiple organ dysfunction in 7 cases,and viral meningitis in 7 cases.10 infants had significantly elevated brain natriuretic peptide (BNP) and troponin Ⅰ,and those with troponin Ⅰ above 20 μg/L had poor prognosis.A comprehensive treatment of limiting liquid volume,high-dose adrenocortical steroids,and IVIG were carried out.Meanwhile,therapy to prevent shock,improve cardiac function,reverse arrhythmia,and mechanical ventilation were used in children with dyspnea.7 cases were cured and 6 patients were followedup for 6 to 12 months.Among the 6 followed-up patients,within 1 ～3 months after discharge,4 cases had normal echocardiogram,and persistently abnormal echocardiogram were found in the other 2 cases and eventually confirmed as dilated cardiomyopathy.4 patients were dead.Conclusion The clinical manifestations of neonatal fulminant myocarditis are unspecific.It's difficult to recognize the early symptoms,missed and delayed diagnosis are common,resulting in high mortality rate.Timely diagnosis and effective treatment can improve the survival rate.

Objective:To investigate the relationship between the down-regulation expression of sodium taurocholate cotransporting polypeptide (NTCP) in proliferating hepatocytes and the response to antiviral therapy of chronic hepatitis B (CHB) patients.Methods:Sixty-eight hepatitis B e antigen (HBeAg)-positive CHB patients admitted to the Fifth Medical Center of PLA General Hospital from January 2011 to March 2015 were included. Basic information and laboratory data were collected. Based on the baseline (before antiviral treatment) inflammatory activity (G), the patients were divided into ≤G2 group and >G2 group. Twelve liver puncture tissue samples were selected from each group for NTCP and Ki67 immunofluorescence staining.The proportion of Ki67-positive cells was calculated, and the staining of NTCP was scored. Five pairs of tissue specimens of patients who had hepatitis B virus (HBV) infection were diagnosed with focal nodular hyperplasia (FNH) and underwent nodular resection surgery from March 2014 to March 2017 were collected.Immunohistochemical staining was used to detect the expressions of Ki67, NTCP and hepatitis B surface antigen (HBsAg) in each tissue specimen, and the proportion of staining positive cells or the staining intensity was calculated. Statistical analysis was performed by Mann-Whitney U test, chi-square test or Spearman correlation analysis. Results:The proportion of Ki67-positive cells (6.75%(6.20%, 8.16%))in five liver FNH tissues with HBV infection was significantly higher than that in adjacent non-FNH tissues (0.75%(0.66%, 1.20%)), while the immunohistochemical scores of NTCP and HBsAg (3.00 (1.00, 3.00) and 2.00 (1.00, 2.00), respectively) were both significantly lower than those in adjacent non-FNH tissues (8.00 (8.00, 9.00) and 8.00 (6.00, 8.00), respectively), the differences were all statistically significant ( Z=-2.611, -2.424 and -2.635, respectively, P=0.009, 0.015 and 0.008, respectively). There were 37 patients in >G2 group, and 31 patients in ≤G2 group. After six months of antiviral treatment, CHB patients with persistent inflammation in >G2 group obtained a better virological response, with serum HBV DNA and HBeAg showing a greater decline ((0.71±0.14) lg IU/mL and (0.92±0.13) lg IU/mL, respectively) than those in ≤G2 group ((0.54±0.30) lg IU/mL and (0.49±0.65) lg IU/mL, respectively) ( Z=-3.048 and -2.666, respectively, P=0.002 and 0.008, respectively). The proportion of Ki67-positive cells in the specimens of >G2 group (4.34%(1.84%, 8.77%)) was significantly higher than that of ≤G2 group (0.34%(0, 0.80%)) ( Z=-3.640, P<0.01), and the immunohistochemical staining score of NTCP (1.00 (0, 3.25)) was significantly lower than that of ≤G2 group (6.00 (4.00, 8.00)) ( Z=-3.012, P=0.003). Spearman correlation analysis showed that the NTCP immunohistochemical score was negatively correlated with the proportion of Ki67-positive cells ( r=-0.512, P=0.01). Conclusions:CHB patients with persistent inflammationare often accompanied by more active hepatocyte proliferation and low membrane NTCP expression, which is not conducive to HBV reinfection. It may facilitate these patients to obtain better virological response.

Pneumonic plague that originated in Russian Siberia broke out in Northeast China in October 1910-March 1911. On the basis of field visits, autopsy, bacteriological identification, and close collaboration with local authorities and international colleagues, Dr. Wu Lien-Teh implemented a series of efficient antiplague measures, which successfully controlled the development of an extraordinary epidemic plague. In his subsequent work, Dr. Wu demonstrated the respiratory transmission of pneumonic plague and tarbagans' role in this spread. Dr.Wu's academic and cultural contributions are valuable in the medical progress in China.

Nucleos(t)ide analogs (NAs) are one of the two main antiviral agents used in clinical practice, which can effectively inhibit HBV replication. Serum HBV DNA is one of the most commonly used virologic markers used to assess HBV replication level. In recent years, more and more studies have suggested that serum HBV RNA is one of the ideal surrogates of cccDNA activity. This article summarized the influence of serum viral nucleic acid properties and quantitative result during treatment with NAs, as well as current method of viral nucleic acid quantification. And finally, it evaluates the significance of HBV DNA and RNA joint testing for CHB treatment.

Objective:To learn the application of nosocomial infection prevention and control measures as stipulated in COVID-19 emergency plans by medical institutions at all levels in the region, for the purpose of strengthening epidemic prevention and control.Methods:During March 12-13, 2020, customized questionnaires were used to learn from 186 hospitals and medical institutions regarding the basics of their nosocomial prevention management departments, emergency plan application and revisions made. Comparison of the ratios or constituent ratios were tested with χ2 test, while the continuous variables analysis between groups was verified with one-way ANOVA. Results:77.53% of the medical institutions had set up independent nosocomial infection management departments, and 87.30% of the institutions were qualified. 80% of the medical institutions had in place emergency plans for respiratory infectious diseases, but 98.05% of them had revised their plans during the pandemic, with an average of 10.85 newly added and revised provisions. Only 30.11% of emergency planed provide for clearly graded early warning.Conclusions:Efforts should be upgraded to develop an emergency prevention and control system for infection prevention and control in epidemics, and improve technical support for infection prevention and control in the system; to strengthen the clearly-graded early warning and graded responses in a scientific manner; and conduct regular drills, revise plan to ensure its applicability.
