Through the exploration and practice,the interventional nursing care has become an important part of Interventional Radiology,which bears a close relations to the pros and cons of the interventional therapeutic quality.The interventional nursing has been developing along the direction to become an independent nursing specialty.At the same time,various issues that affect the interventional nursing development start to emerge.At present,the setting up of a system to strengthen the establishment of the special care unit and human resources is urgently needed.The following measures are indispensable to promote the sustainable development of interventional care: to raise special awareness,to work out nursing routine and quality control standards,to explore the proficiency in order to stabilize nursing team,to pay attention to specialty education and to establish an integration mode for standardized training and professional development.

Serum Ca, P, AKP, plasma iPTH, cAMP, urinary Hyp and BMC were measured in 31 cases of Graves' disease. The results showed that about 66.67% of the patients (including 21 controlled and 10 uncontrolled cases) had a decreased BMC, while serum Ca, P, plasma iPTH, cAMP were within the normal range. The data also showed that about 54.6% of the patients had increased serum AKP, but it would not exceed 25 U if no hepatic disease existed. There were positive correlations between serum T, and urinary Hyp, and between urinary Hyp and serum AKP, but a negative correlation between urinary Hyp and BMC. It was suggested that serum AKP and urinary Hyp could be considered as the indices of negative balance of bone metabolism in Graves' disease, and probably it was induced by excessive thyroid hormone directly.

Objective To master the serum nickel change rule of acute nickel carbonyl poisoning in rats,and to provide laboratory support for clinical treatment of acute nickel carbonyl poisoning patients.Methods SPF rats were given nickel carbonyl (250mg/m3,500mg/m3) in static inhalation for 30min.Rats were anesthetized by ether for 15 seconds after exposure for 30min,2h,4h,8h,12h,24h,48h,72h and 7d respectively.Anatomized rats,kept blood collection 2-3mL,and separated serum 0.5-1mL.Serum nickel was detected by AA800 (American PE company).Results The average serum nickel levels of 250mg/m3 dose group at 30min,2h,4h,8h,12h,24h,48h,72h,7d were (33.69 ±2.59),(24.61 ±3.03),(27.83 ±5.69),(21.36 ±4.14),(20.39 ±4.14),(18.80 ±7.02),(14.51 ±8.21),(13.58 ± 5.78) and (12.83 ± 4.41)μg/L.30 minutes reached the peak,and was 5.30-fold of those in normal controls.There had significant differences compared with normal control(t =5.959,5.958,5.990,5.998,5.997,5.994,5.990,4.317,4.347,all P ＜ 0.01).The average serum nickel levels of 500mg/m3 dose group at 30min,2h,4h,8h,12h,24h,48h,72h,7d were (72.22 ± 1.62),(57.78 ± 12.99),(42.25 ± 7.25),(103.77 ± 11.11),(79.04 ±12.26),(26.35 ±6.56),(18.58 ±4.92),(17.22 ±9.73),(14.59 ±5.27) μg/L.8h reached the peak,and was 16.33-fold of normal controls.The differences were significant (t =5.960,5.947,5.978,5.927,5.948,5.959,3.143,2.447,2.440,all P ＜ 0.05).Meanwhile,there were significant differences between two groups of 30min,2h,4h,8h,12h(t =5.208,2.447,2.449,5.959,5.959,P =0.001,0.049,0.042,0.000,0.000),but there was no significant difference after 24h.Conclusion There was significant doses-effect relationship between serum nickel content of acute nickel carbonyl poisoning rats and the dosage.Nickel carbonyl or its metabolites were excreted mainly within 24h.

Objective To explore the applications of standardized patients teaching method in clin-ical practice teaching effect for students majoring in rehabilitation therapy in the course of occupation therapy. Methods The 2013 classes of rehabilitation therapy specialty in our college were selected as the subjects of study in the two groups. Group 1 was taught by the traditional teaching method, while group 2 was taught by the standardized patients (SP) teaching method. After learning, we made an analysis of two groups through the form of theory questions, practical operation and the questionnaire to assess the teaching efficacy. Measurement data using two sample mean t-test after SPSS 13.0 software for statistical analysis. Results The scores of skills test and questionnaire in students taught by SP teaching method is signifi-cantly higher than those in students taught by traditional teaching method (P<0.05). In the theoretical exami-nation, the SP teaching group outperformed the traditional teaching group, but the difference was not statis-tically significant. Conclusion In occupation therapy application, SP teaching is superior to traditional teaching in improving students' ability of analysis and judgment, operation skill and communication level, which can be extended to other clinical courses of rehabilitation therapy.

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.

Objective:The aim of this study was to explore the associations of muscle size and density with handgrip strength(HGS)and the Timed Up and Go(TUG)test.Methods:Totally 301 participants living in the Xinjiekou community near Beijing Jishuitan Hospital were recruited for CT imaging of the hip and a 1-cm slice of the mid-thigh.The cross-sectional area and density of the gluteus maximus and the mid-thigh muscles were estimated by the Osirix viewer based on CT images.HGS and TUG were also performed in these subjects.Logistic regression analysis was used to evaluate the correlations of muscle density and size with TUG and grip strength.Results:In women, after adjustment for age and BMI, the density of the gluteus maximus was negatively correlated with TUG( P trend=0.0366), while the size of the gluteus maximus and the mid-thigh muscles was not correlated with TUG.In men, the density or size of these muscles was not correlated with TUG.After adjustment for age and BMI, the density of the gluteus maximus was positively correlated with grip strength( P trend=0.0334)and the size of the mid-thigh muscles was also positively correlated with grip strength( P trend=0.0155)in men, but they were not correlated with grip strength in women. Conclusions:There were sex differences in the relationship between muscle size or density and grip strength or timed up and go.The density of the gluteus maximus is associated with muscle strength and physical performance while the size of the mid-thigh muscles is correlated with muscle strength.

Objective: To investigate the expression of survivin, fibronectin-1, vascular endothelial growth factor (VEGF) and ezrin in thyroid tumors and their relationship with the pathological characteristics of thyroid tumors. Methods: Ninety patients with thyroid tumors admitted to the third affiliated hospital of Zunyi Medical University and the first hospital during Oct. 2016 and Oct. 2018 were selected as the observation group. Seventy-five patients with normal thyroid confirmed by pathology in the same period were selected as the control group. The protein levels of survivin, fibronectin-1, VEGF and ezrin were detected by immunohistochemical method. Results: The positive rates of survivin, fibronectin-1, VEGF and Ezrin in the control group were 2.67%, l4.00%, 1.33% and 1.33%, which were lower than 97.78%, 96.67%, 93.33% and 95.56% in the observation group, respectively (all P<0.05 or P<0.01). The expressions of survivin, fibronectin-1, VEGF and ezrin were significantly correlated with TNM staging, tumor diameter, extrathyroid invasion and lymphatic metastasis (all P<0.05). Conclusion: Survivin, fibronectin-1, VEGF and ezrin proteins are all involved in the occurrence and development of thyroid tumors. The combined detection of these four indicators is of great significance in the diagnosis, treatment and prognosis of thyroid tumors.

Objective: To investigate the correlation between the diversity of biliary bacterial flora and the recurrence of common bile duct stones. Methods: From September 2018 to March 2019, 48 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) at the First Affiliated Hospital of Nanjing Medical University were enrolled and divided into primary choledocholithiasis (primary group, 38 patients) and recurrent choledocholithiasis group (recurrent group, 10 patients). The bile of the patients of the two groups was collected and analyzed with high-throughput sequencing of 16S rRNA. The Chao1 estimator indicated the richness of the biliary bacterial flora, and Shannon index and Simpson index demonstrated the diversity of biliary bacterial flora. The bacterial flora distribution was explored from different levels of phylum, class, order, family, genus and species. Chi-square test and t test were performed for statistical analysis. Results: The Chao1 estimator of the primary group was higher than that of the recurrent group (419.413±118.704 vs. 396.000±70.483), and the difference was statistically significant (t=3.130, P=0.003). At the level of the phylum, the highest abundance of bacteria in the primary group was Firmicute (56.48%), the highest abundance of bacteria in the recurrent group was Proteobacteria (57.79%). The dominant bacteria of the recurrent group was Proteobacteria, which was inconsistent with that of the primary group, and there were significant differences in the distribution of Proteobacteria and Firmicute between two groups (χ²=0.962 and -2.619, both P<0.05). At the genus level, the abundance of Bacillus and Lactococcus of the recurrent group were both lower than those of the primary group (9.75% vs. 20.77%, 10.86% vs. 22.01%, respectively), and the differences were statistically significant (χ²=0.354 and 0.503, both P<0.05). The abundance of Morganella of the recurrent group was higher than that of the primary group (9.00% vs. 0.44%), and the difference was statistically significant (χ²=-2.025, P=0.049). At the species level, the abundance of Bacillus unclassified, Carnobacterium maltaromaticum and Bacillus circulans of the primary group were all higher than those of the recurrent group (17.78% vs. 8.84%, 2.39% vs. 1.11%, 2.59% vs. 0.74%, respectively), and the differences were all statistically significant (χ²=2.540, 2.643 and 2.515, all P<0.05). The abundance of Aeromonas veronii of recurrent group was higher than that of the primary group (2.04% vs. 0.01%), and the difference was statistically significant (χ²=-2.397, P=0.021). The bacteria that had significant effects in the primary group included Lactococcus (P=0.012), Lactobacillus (P=0.033) and Geobacillus (P=0.021), while in the recurrent group, which included Enterobacter (P=0.007), Aeromonadaceae (P=0.001), Actinomycetes (P=0.009), and Aeromonas (P=0.001). Conclusions There are differences in abundance and composition of biliary bacterial flora between the recurrent group and the primary group. It remains to be further studied whether the changes of some bacterial flora correlated with the recurrence of common bile duct stones.
