Objective To explore true thoughts and experience about student-based nursing teaching rounds among vocational college nursing students in Pediatric during the initial stage of clinical practice.Methods Interview was conducted on 27 nursing students of seven focus groups with semi-structured interview.The data was transcribed based on the tape and were analyzed by Giorgi analysis.Results Nursing students held positive attitude to this mode.Three themes were extracted:stimulating nursing students' learning potential,enhancing the comprehensive ability of nursing students; some students had difficulties in case selection,disease analysis and physical examination; suggesting that detailed rounds guideline should be issued to students first,and teaching rounds should be held every two weeks.Conclusions We should strengthen training of the ability of nursing assessment in pediatrics for nursing students,play the role of facilitator and advocate self-directed learning methods.

[ ABSTRACT] AIM:To investigate the effects of Chaihu Shugan powder ( CSP) on lipid metabolism and the pro-teins involved in adenosine 5’-monophosphate-activated protein kinase (AMPK)/sirtuin 1 (SIRT1) pathway in the liver tissues of the rats with non-alcoholic fatty liver disease (NAFLD).METHODS: Sprague-Dawley rats were randomly di-vided into normal control ( NC) group, with HFD ( HFD) group and CSP group.The NAFLD models were established by feeding with HFD for 16 weeks in the rats.The rats in CSP group were intragastrically administered with CSP extracts (9.6 g· kg-1 · d-1 ) , and blood and liver samples were collected 16 weeks later.Serum and liver levels of total cholesterol ( TC) and triglyceride ( TG) , and serum levels of alanine aminotransferase ( ALT) and aspartate aminotransferase ( AST) were measured using an automatic biochemical analyzer.The histological changes of liver tissues were observed with HE staining, while the lipid deposition was observed with Oil Red O staining.The ultrastructural changes of the liver tissues were observed under transmission electron microscope.Moreover, the protein levels of AMPK, phosphorylated AMPK (pAMPK), SIRT1 and uncoupling protein 2 (UCP2) in the liver were detected by Western blot.RESULTS:The results of HE staining, Oil Red O staining and electron microscopy demonstrated that NAFLD rat model was successfully estab-lished.Compared with NC group, the serum and liver levels of TC and TG, and serum level of AST in model group were markedly elevated ( P<0.01) .Moreover, the protein levels of pAMPK and SIRT1 in HFD group were markedly reduced (P<0.01), whereas UCP2 level was elevated (P<0.01).Furthermore, liver levels of TC and TG, and serum level of AST in GSP group were markedly reduced as compared with HFD group ( P<0.05 ) .The protein levels of pAMPK and SIRT1 were elevated ( P<0.05 ) , whereas the UCP2 level was reduced as compared with HFD group ( P<0.01 ) .The protein level of AMPK between the 3 groups had no significant difference.CONCLUSION: CSP attenuates hepatic lipid disorder and hepatic lipid deposition in NAFLD rats induced by feeding with HFD for 16 weeks, which is associated with the activation of AMPK/SIRT1 pathway.

【Objective】 To explore the factors affecting NAT reactive blood donors re-entry, so as to provide data support for formulation of scientific and reasonable strategy. 【Methods】 The basic data and laboratory test results of 174 NAT reactive returning blood donors from January 2019 to August 2021 were collected and statistically analyzed by logistic regression. 【Results】 Among 174 HBV DNA reactive blood donors applying for re-entry, 81 (46.6%) were eligible for re-entry. Blood donation type and deconstructed Ct value were independent influencing factors of blood donors’ re-entry (P<0.05). The Ct value of minipool and deconstruction test showed significant affection on the re-entry (P<0.05). Donors with minipool-Ct-value exceeding deconstructed-Ct-value had a low likelihood of success with re-entry(P>0.05). No significant difference was observed in Ct values of deconstruction test, first re-entry test and second re-entry test (P<0.05). 【Conclusion】 In view of the low re-entry rate of NAT reactive blood donors, it is necessary to establish a set of safety criteria to lessen workloads. Donors with exceeding minipool-Ct-values, repeat reactive by two NAT reagents, failure in the first re-entry test are suggested to be deferred permanently.
