Objective By detecting the mutations spectrum of phenylalanine hydroxylase(PAH)gene in phe-nylketonuria(PKU)patients and their parents. The researchers analyzed the gene mutation features and high - frequency mutations and determined the relationship between the genotype and the phenotype,which would provide a theoretical basis for the early diagnosis and genetic consultation of PKU children in the region. Methods In this study,13 exons and their flanking introns of the PAH gene in 32 PKU patients and their parents from Wuxi and Suqian in Jiangsu province were sequenced by using the next - generation sequencing(NGS)technology. Results Sixty - one mutant sites and 32 mutant genes were detected in 32 PKU patients,and the mutation detection rate was 95. 31%(61 / 64 cases). The variants at c. 721C ﹥ T,c. 1068C ﹥ A,c. 611A ﹥ G,c. 1197A ﹥ T,c. 728G ﹥ A,c. 331C ﹥ T and c. 442 -1G ﹥ A were common mutations in the region with mutation frequency over 5% . What's more,4 novel variants of c. 699C ﹥ G,c. 265C ﹥ T,c. 722G ﹥ A and c. 1194A ﹥ G were found. Of those,c. 699C ﹥ G was not recorded in the PAH variant database and HGMD database and. c. 265C ﹥ T,c. 722G ﹥ A,and c. 1194A ﹥ G were first reported in the Chi-nese population. Genotype - accurate biochemical phenotype correlation by using the Guldberg AV system revealed con-sistency rate of 38. 0%(8 / 21 cases),which the consistency rate between accurate biochemical phenotype and predic-tive phenotype of moderate to severe genotype was 92. 3%(12 / 13 cases),and mild genotype was 50. 0%(4 / 8 cases). Conclusions The PAH gene variants of PKU patients in Jiangsu province are distributed mainly in exons 7,of which the highest frequency gene mutation is c. 721 c ﹥ T. Moreover,one novel variant c. 699C ﹥ G was reported for the first time. The PKU children inherit the PAH mutation gene mainly from both parents. There are definite correlation between the genotypes and phenotypes.

Objective To investigate the hospital work environment management, nurses' self-efficacy and work engagement and to explore the correlations among them. MethodsFrom March 2017 to March 2018, we selected 310 clinical nurses of three hospitals in Jinhua by convenience sampling. The investigation was carried out with the self-designed general information questionnaire, Chinese version of Practice Environment Scale (PES), General Self-Efficacy Scale (GSES) and Utrecht Work Engagement Scale (UWES). Correlation analysis was used to related data after being organized. In this study, 310 questionnaires were issued and 306 valid questionnaires were collected, with an effective recovery rate of 98.71%. ResultsAmong 306 nurses, the scores of PES, GSES and UWES were (95.25±12.17), (25.58±5.13) and (52.38±8.81) respectively. Pearson correlation analysis showed that the dimension scores of PES had positive correlations with the dimension scores of self-efficacy and work engagement (P<0.05);nurses' self-efficacy was positively correlated with the dimension scores of work engagement (P<0.05). Stepwise regression analysis used to explore the influence of work environment management between nurses' work engagement and self-efficacy showed that self-efficacy had a partial mediating effect between work environment and work engagement accounting for 37.64% of the total effect. ConclusionsNurses' work engagement has correlations with self-efficacy and work environment, and plays a mediating effect between them. Improving work environment management and nurses' self-efficacy can improve nurses' work engagement so as to provide the good nursing care for patients.

Objective:To explore the predictive value of complement and coagulation indicators in sepsis related acute kidney injury (AKI).Methods:Clinical data of 217 patients with sepsis admitted to the Department of Internal Medicine and Intensive Care Unit of Affiliated Hospital of Jiangnan University from January 2018 to June 2019 were retrospectively analyzed. All patients were divided into sepsis with AKI group and without AKI group. Laboratory indicators of all patients were collected, including complement C 3, complement C 4, activated partial thrombin time (APTT), prothrombin time (PT), international normalized ratio (INR), D-dimer, procalcitonin(PCT), etc. logistic regression analysis was used to explore the risk factors of sepsis related AKI. Receiver operating characteristic curve (ROC) was used to evaluate the predictive value of independent risk factors. Results:Among 217 patients, 120 patients developed sepsis related AKI and 97 patients didn′t. PCT, lactic acid, PT, APTT, INR and D-dimer in AKI patients were significantly higher than those without AKI ( P<0.01). Complement C 3 and complement C 4 were significantly lower in AKI group ( P<0.01). Multivariate logistic regression analysis suggested that blood pressure<90/60 mmHg (1 mmHg=0.133 kPa)( OR=3.705, 95% CI 1.536-8.934, P=0.004), increased lactic acid ( OR=1.479, 95% CI 1.089-2.008, P=0.012), decreased complement C 3 ( OR=0.027, 95% CI 0.005-0.152, P<0.001) and prolonged APTT ( OR=1.090, 95% CI 1.047-1.137, P<0.001)were independent risk factors predicting AKI. The area under the ROC curve (AUC) of these multivariates were 0.741 (95% CI 0.675-0.807), 0.798 (95% CI 0.732-0.864), 0.712 (95% CI 0.643-0.781) and 0.716 (95% CI 0.648-0.783) respectively. The relevant sensitivity was 57.5%, 80.8%, 87.5%, 59.2%, and the specificity was 90.7%, 75.3%, 51.5%, 77.3%, respectively. The AUC of the combined four indicators was 0.880 (95 %CI 0.835-0.926) with the sensitivity 75.0% and the specificity 90.7%. Conclusion:The low level of complement C 3 and prolonged APTT predict sepsis related AKI, and the predictive value can be enhanced if hypotension and hyperlactacidemia are added.
