BackgroundThe professional self-concept of nurses is a crucial indicator for their personal growth， development and career planning. Previous studies have shown that work stressors during the internship period may lead to a decrease in the level of professional self-concept among nursing students. Given the existing differences in social roles between nursing students and clinical nurses， the influencing factors of professional self-concept in clinical nurses and its relationship with work stressors require further research. ObjectiveTo explore the relationship between work stressors and professional self-concept among nurses， so as to provide references for improving the level of professional self-concept of clinical nurses. MethodsFrom December 2022 to February 2023， a stratified random sampling method was employed to select 260 in-service nurses from Mianyang Hospital of Traditional Chinese Medicine as the study subjects. Chinese Nurses Stressor Scale （CNSS） and Professional Self-concept of Nurses Instrument （PSCNI） were used for assessment. Pearson correlation analysis was conducted to examine the correlation between CNSS scores and PSCNI scores of nurses. Multiple linear regression analysis was utilized to explore the factors influencing the professional self-concept of nurses. ResultsA total of 238 nurses （91.54%） completed valid questionnaires. PSCNI total score yielded a statistical difference among nurses with different marital statuses （F=8.947， P<0.05）. PSCNI total scores were significantly higher in nurses with emergency medical service experience than those without such experience （t=2.208， P<0.05）， and were significantly lower in nurses with abnormal physical examination findings in the past year than those without abnormal findings （t=-2.584， P<0.05）. Correlation analysis revealed that CNSS total score and subscale scores were negatively correlated with PSCNI total score （r=-0.275~-0.169， P<0.01）. Multiple linear regression analysis indicated that work expectation-related stressors， marital status and emergency medical service experience might be influencing factors of their professional self-concept （β=-0.350， 0.345， 0.183， P<0.01）. ConclusionNurses' work stressors are closely correlated with their professional self-concept， and high levels of stressors related to nurses' expectations may lead to a decrease in their professional self-concept levels. ［Funded by 2021 Research Project of Mianyang Municipal Health Commission （number， 202154）］

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Object:To explore the effects of shared decision making-based intervention on decisional conflict and health literacy in stable coronary artery disease patients.Methods:A total of 86 stable coronary artery disease patients were divided into experimental group and control group according to the admission order, with 43 cases in each group. The patients in the control group recieved routine nursing, basis on this, the experimental group carried out shared decision making program. Before and after 1 month of intervention, the effects was assessed by Decisional conflict scale (DCS) and Health literacy management scale (HeLMS), respectively.Results:Before intervention, there was no significant difference in DCS and HeLMS scores between two group( P>0.05). After intervention, the information & values, decision uncertainty and total DCS scores were (6.95±2.13) pionts, (3.44±1.18) pionts and (20.95±3.99) pionts, significantly lower than in the control group (8.77±2.33) pionts, (4.95±1.46) pionts, (25.56±4.03) pionts; the information acquisition ability, interaction ability, willingness to improve health, willingness of financial support and total HeLMS scores were (36.77±4.85) pionts, (35.74±4.58) pionts, (15.07±1.55) pionts, (6.53±1.76) pionts, (94.12±6.44) pionts, significantly higher than in the control group [(34.37±5.84) pionts, (33.19±5.90) pionts, (14.23±1.43) pionts, (5.81±1.29) pionts, (87.60±9.18) pionts], the difference was statistically significant ( t values were 2.070-5.321, P<0.05). Conclusion:Shared decision making can effectively alleviate decisional conflict and improve health literacy of patients with stable coronary artery disease.

ObjectiveTo explore the role of supportive psychotherapy in mental health improvement of COVID-19 positive patients， and to provide references for the implementation of early psychological intervention measures in response to the sudden epidemic outburst， such as COVID-19. MethodsA total of 35 patients with severe COVID-19 admitted to ICU ward of Wuhan People’s Hospital from February 1 to March 1， 2020 were enrolled in this study. All the selected individuals received a 2-week supportive psychotherapy. Then Pittsburgh Sleep Quality Index （PSQI）， Patients’ Health Questionnaire Depression Scale-9 item （PHQ-9）， Generalized Anxiety Disorder Scale （GAD-7） and Social Support Rating Scale （SSRS） were used to evaluate the sleep quality， depression， anxiety and social support of participants at the baseline and the 2^nd week of the intervention. ResultsInsomnia was detected in 32 patients （91.43%）， anxiety symptoms in 31 （88.57%）， depressive symptoms in 32 （91.43%）， and 29 patients （82.86%） reported feeling a lack of social support. After 2 weeks of intervention， the PSQI， GAD-7 and PHQ-9 scores decreased （t=5.272， 5.475， 4.621， P<0.01）， and SSRS score increased （t=-4.639， P<0.01）. After the intervention， the proportion of patients with insomnia， anxiety， depression and lack of social support was also decreased （χ²=18.714， 16.232， 16.970， 4.480， P<0.01）. ConclusionSupportive psychotherapy may ameliorate anxiety， depression and sleep quality in COVID-19 patients.

Objective:Mesenteric fat hypertrophy is present in about a quarter of Crohn′s disease (CD) patients and it can be easily detected by bowel ultrasound (US). The purpose of this research was to assess the correlation between mesenteric fat hypertrophy and behavior and activity of CD.Methods:A total of 89 CD patients who admitted to the First Affiliated Hospital of Nanjing Medical University from August 2018 to November 2019 were recruited in this study. The total CD patients were divided into two groups depending on with or without mesenteric fat hypertrophy by US tests. Crohn′s disease activity index (CDAI), simplified endoscopic score for Crohn′s disease (SES-CD), serum inflammatory indicators and fecal calprotectin were assessed.Results:Mesenteric fat hypertrophy was significantly associated with stricturing behavior (B2, P<0.01). CDAI ( P=0.002) , blood platelet ( P=0.001) , C-reactive protein ( P=0.024) , fecal calprotectin ( P=0.004) and bowel wall thickness ( P<0.01) in patients with mesenteric fat hypertrophy were significantly higher than those without, but not the erythrocyte sedimentation rate ( P=0.110) and SES-CD ( P=0.115) . Serum albumin ( P=0.001) in patients with mesenteric fat hypertrophy was lower than that in patients without mesenteric fat hypertrophy. Conclusion:Mesenteric fat hypertrophy is correlated with intestinal stenosis and disease activity in patients with Crohn′s disease.

Objective To evaluate the role of a color jaundice card (6 colors) as a possible screening tool for detecting neonatal hyperbilirubinemia.Methods During February 1,2016 and May 31,2017,neonates were enrolled in the study,with gestational age ≥35 weeks,birth weight ≥2 000 g,postnatal age 3-28 days,who were the outpatients or inpatients of the 9th People's Hospital of Wuxi Affiliated to Soochow University and the People's Hospital of Anyang.In a well-lighted room,the card measurements were performed at the infants' forehead,the cheek and the sternum.The skin was pressed with a finger for 2 seconds and left quickly,and then the card was used to compare with the exposed yellow skin.Within 2 hours after jaundice card measurement,blood was obtained by venipuncture and total serum bilirubin (TSB) levels were measured.The sensitivity,specificity,positive predictive value (PPV),negative predictive value (NPV),positive likelihood ratio (PLR) and negative likelihood ratio (NLR) were calculated at each measurement sites.Results One hundred and thirty-two neonates were enrolled,of whom 68 cases (51.5％) were male and 64 cases(48.5％) were female and 18 cases (13.6％) were preterm and 114 cases (86.4％) were term neonates.Among all neonates,TSB was ＜5.00 mg/dL(1 mg/dL =17.1 μmol/L) in 21 cases (15.9％),5.00-9.99 mg/dL in 26 cases (19.7％),10.00-14.99 mg/dL in 34 cases (25.8％),15.00-19.99 mg/dL in 37 cases (28.0％) and ≥ 20.00 mg/dL in 14 cases (10.6％).The card had the highest cap ability to recognize jaundice at the cheek,slightly lower at the sternum and the worst in the forehead.The cut-off of ≥ 12 on the six-color card at the cheek had a sensitivity of 95.95％,specificity of 74.14％,PPV of 82.56％,NPV of 93.48％,PLR of 3.710 and NLR of 0.055 for identifying neonates with TSB ≥ 12 mg/dL,with sensitivity being 98.08％,specificity 57.50％,PPV 60.00％,NPV 97.87％,PLR 2.308 and NLR 0.033 for TSB≥ 15 mg/dL.The identification rate was as follows:sensitivity of 100.00％,specificity of 46.00％,PPV of 37.21％,NPV of 100.00％ and PLR of 1.852 for predicting TSB ≥ 17 mg/dL.In addition,in the forehead,cheeks and sternum,the sensitivity of the cut-off of ≥ 12 on the card was 100.00％ for identifying neonates with TSB≥20 mg/dL.In the cheeks and the sternum,the cut-off of ≥ 15 on the card was with a sensitivity of 100.00％ for predicting TSB ≥ 20 mg/dL.Conclusion The six-color jaundice card is a potential screening tool for neonatal hyperbilirubinemia,and the cheek is the best measurement site.

There was no significantly difference of the adverse reaction rates of the two groups during treatment (χ²=0.134, P=0.714). Conclusions The Wumeiwan combined with triple therapy for treatment of CAG has a good efficacy and low adverse reactions, has serious anti-inflammatory effects, can improve the body immunity, and it was worthy clinical application.

OBJECTIVES: To investigate the otoprotective effects of mouse nerve growth factor (mNGF) in A/J mice. METHODS: The mice at postnatal day 7 (P7) were randomly separated into a mNGF treated group (mNGF group) and a distilled water (for injection) treated group (control group). The mNGF dissolved in distilled water or distilled water alone was given to the mice once every other day from P7 by intramuscular injection in the hips. The otoprotective effects of mNGF in A/J mice were observed in a time course manner. The thresholds of auditory-evoked brainstem response (ABR) were tested from the age of the 3rd to the 8th week. Sections of the inner ears were stained by hematoxylin and eosin, and spiral ganglion neurons (SGNs) were observed at the age of the 3rd, the 6th,and the 8th week. Counts of whole mount outer hair cells (OHCs) in the cochleae were made at the age of 8 weeks. Expression of apoptosis related genes was determined by quantitative real-time polymerase chain reaction and Western blotting. RESULTS: ABR thresholds of the mNGF group were significantly lower than those of the control group at the age of the 6th and the 8th week. Moreover, the mNGF preserved OHC and SGN in the mouse cochleae in this period. Further experiments showed that the expression of caspase genes (including caspase-3) was inhibited in the mouse inner ears in the mNGF group. CONCLUSION: The mNGF improves hearing in A/J mice by preserving SGN and OHC in the cochleae.

Objective To observe the morphological changes of carotid artery wall by ultrasonography in patients with Takayasu arteritis,and to evaluate the diagnostic value of contrast-enhanced ultrasonography for active Takayasu arteritis.Methods High-frequency ultrasound technique was used to analyze the morphological changes of the carotid artery in 40 patients.NIH score was used as the gold standard and the complete clinical data and acute phase reactors were recorded.T test,Chi-square test,sensitivity and specificity were calculated for statistical analysis.Results The thickness of carotid artery wall in active group was much more thickened than the non-active group [(2.2±0.6) mm vs (1.8±0.5) mm,t=-2.142,P＜0.05].The CDD [(0.89±0.06) in active group vs (0.95±0.03) in non-active group,t=3.683,P＜0.01] and RDD [(0.17±0.06 in active group vs (0.09±0.05) in non-active group,t=-4.020,P＜0.01] were significantly different between the two groups.The distribution of neovascularization in the carotid artery wall of the active group was more diffuse in the central part of the wall.The sensitivity and specificity of contrast-enhanced ultrasonography to diagnose the active of Takayasu arteritis were 72.7％ and 87.5％ respectively,and the positive predictive value and the negative predictive value were 80.0％ and 82.4％ respectively.Conclusion Contrast-enhanced ultrasonography can be used as an effective way to assess the disease activity of TA patients.

Objective To evaluate the performance of Positron emision tomography (PET) in the assessment of disease activity of Takayasu arteritis (TA). Methods Information retrieval was based on database such as PubMed/Medline and CNKI, etc. The research before Dec 2016 involving Takayasu arteritis and PET were included.The quality of the research was evaluated by diagnostic accuracy studies-2Q(UADAS-2) and the data was analyzed by Meta-disc. Results Among the 70 research, nine studies were included in this study with a total of 126 patients and 254 controls. All patients were diagnosed according to the classification criteria of American College of Rheumatology. The disease activity was mostly assessed by the scoring system of National Institutes of Health and by clinical assessment in one study. The result of PET was evaluated by visual grade and semi-quantitative analysis. The pooled DOR of the 9 studies was 17.54, the pooled sensitivity and specificity was 84% and 73%,respectively.However,the heterogeneity of specificity was 81.4%. Two studies had included one patients repeatedly and suspected active patients were included in the in-active group in one study,which might impact the statistical result of the meta-analysis.After excluded these studies, the pooled DOR was 30.32. The pooled sensitivity and specificity was 86% and 85%, respectively, with better consistency. Conclusion PET shows stable sensitivity and variant specificity in the diagnosis and assess of disease activity of TA, which is a useful method in the clinically evaluation of disease activity of TA.
