Polymorphisms of host tropism relating amino acid sites in influenza A virus / 上海预防医学

ObjectiveTo discover and analyze single or several correlative key amino acid sites that influence the host tropism during the influenza A virus （IAV） infection based on complete internal protein gene segments of IAV strains， and to provide evidence for the study of human host-adaptive mutations of IAV. MethodsThe full-length nucleotide sequences of 43 671 IAV strains containing 6 complete internal gene segments were downloaded from the GISAID EpiFluTM database， and 698 human-tropic （HU） and 1 266 avian-tropic （AV） representative strains were included. The consensus coding sequences of the representative strains from the amphitropic category were compared by R script， and the differential amino acid sites and their polymorphisms were then obtained. The multi-site combination analysis of differential sites was conducted with R script. ResultsA total of 49 and 57 conserved differential sites were obtained from the consensus sequence comparison between AV and H1N1 （subtype from HU）， and comparison between AV and H3N2 （another subtype from HU）， separately. 79 and 65 multi-site combinations were found between HU and AV strains through 3 and 4 sites combination analysis， respectively， and a total of 11 conserved sites were involved： site 271 and 684 in PB2； site 336， 486， 581 and 621 in PB1； site 204 and 356 in PA； site 33， 305 and 357 in NP. No eligible differential sites were found in M1 and NS1. ConclusionSeveral conserved amino acid differential sites， between HU and AV strains of IAV， are found in PB2， PB1， PA and NP proteins. Instead of working as single units， these sites may have interactions， forming specific amino acid combinations that determine the host tropism of IAV collectively.

Basis of the replacement of short peripheral intravenous catheters for clinical nurses: a qualitative study / 中国实用护理杂志

Objective@#To investigate the current status and influencing factors of basis of the replacement of short peripheral intravenous catheters for clinical nurses and explore the obstruction of the latest guide promoted in practice.@*Methods@#The qualitative research method was adopted, and semistructured interviews were used to interview 11 clinical nurses. Data were analyzed by the method of category analysis.@*Results@#Although the clinical nurses mainly used the national standards to do practical operation, they preferred to carry out catheter replacement according to clinical indications. The difference between the latest guide and the national standards was the main obstruction in the practical promotion of the latest guide.@*Conclusions@#The removal of short peripheral intravenous catheters according to clinical indications is more suitable for clinical practice. Further improving the standards of intravenous therapy in China has become a fundamental measure to solve the contradictions of work of clinical nurses, improve patients′ medical experience and save medical resources.

LINC00703 Acts as a Tumor Suppressor via Regulating miR-181a/KLF6 Axis in Gastric Cancer

PURPOSE: Long noncoding RNA 00703 (LINC00703) was found originating from a region downstream of Kruppel-like factor 6 (KLF6) gene, having 2 binding sites for miR-181a. Since KLF6 has been reported as a target of miR-181a in gastric cancer (GC), this study aims to investigate whether LINC00703 regulates the miR-181a/KLF6 axis and plays a functional role in GC pathogenesis.MATERIALS AND METHODS: GC tissues, cell lines, and nude mice were included in this study. RNA binding protein immunoprecipitation (RIP) and pull-down assays were used to evaluate interaction between LINC00703 and miR-181a. Quantitative real-time polymerase chain reaction and western blot were applied for analysis of gene expression at the transcriptional and protein levels. A nude xenograft mouse model was used to determine LINC00703 function in vivo.RESULTS: We revealed that LINC00703 competitively interacts with miR-181a to regulate KLF6. Overexpression of LINC00703 inhibited cell proliferation, migration/invasion, but promoted apoptosis in vitro, and arrested tumor growth in vivo. LINC00703 expression was found to be decreased in GC tissues, which was positively correlated with KLF6, but negatively with the miR-181a levels.CONCLUSIONS: LINC00703 may have an anti-cancer function via modulation of the miR-181a/KLF6 axis. This study also provides a new potential diagnostic marker and therapeutic target for GC treatment.

A longitudinal study of nursing undergraduates′ humanistic care ability in different stages of clinical practice / 中国实用护理杂志

Objective To do a longitudinal study of nursing undergraduates′ humanistic care ability in different period of clinical practice, and analyze its trend, aiming to provide reference about how to intervene to enhance the nursing undergraduates' humanistic care ability. Methods A total of 67 nursing undergraduates were investigated about their humanistic care ability with the Care Ability Inventory (Caring Ability Inventory, CAI) at the beginning, middle and end of the internship. Results The scores of seniors′ humanistic care ability at the beginning, middle and end of the internship were 194.97±22.93, 192.18±26.87, 187.24±22.15, and there was a statistically significant difference among the three time points (F=3.234, P<0.05), there was significant difference of the dimension of courage in different periods (F=7.511, P<0.01). Conclusions There is a downtrend of nursing undergraduates′humanistic care ability in different stages of clinical practice, and we suggest that nursing educators and administrators should consider the characteristics of different periods in the clinical practice, and then do a targeted training to foster nursing students′humanistic care ability.

Correlation between Supportive Care Need and Quality of Life in Patients with Breast Cancer Accepting Chemo-therapy / 中国康复理论与实践

Objective To observe the level of supportive care need and quality of life in patients postoperation for breast cancer and ac-cepting chemotherapy, and the relationship between them. Methods From September, 2015 to June, 2016, 235 patients with breast cancer af-ter surgery were conveniently sampled, and investigated with the general situation questionnaire, Supportive Care Need Survey Short-form (SCNS-SF34) and Functional Assessment of Cancer Therapy-Breast (FACT-B). Results A total of 230 patients were analyzed. Patients self-reported to need supportive care in all dimensions of SCNS-SF34, and the most frequency was in the health information (31.30％). The score of FACT-B was (93.25±23.53), that needed further improvement. The needs of supportive care in each dimension negatively correlat-ed with the scores of FACT-B in the dimensions (|r|>0.168, P<0.05) except society/family and function. Conclusion The patients with breast cancer need variety of supportive care, which may impact their quality of life.

Effect of Unsupported Arm Exercise on Patients with Chronic Obstructive Pulmonary Disease / 中国康复理论与实践

Objective To explore the effect of unsupported arm exercise (UAE) on dyspnea, exercise endurance of upper limbs and qual-ity of life in patients with chronic obstructive pulmonary disease (COPD). Methods From May to October, 2014, totally 70 patients with COPD were recruited and were randomly assigned to control group and intervention group. Both groups received routine care, and the inter-vention group performed UAE for six weeks additionally. The COPD Assessment Test (CAT), baseline dyspnoea index (BDI) and six-min-ute Pegbord and Ring Test (6PBRT) were recorded.

AIM: To investigate the effects of nitric oxide (NO) on hepatic encephalopathy in cirrhotic rats induced by LPS. METHODS: The cirrhotic model of rats was established by complex pathogeny. Since the end of the 8 th week, the rats were intragastrically-infused with 0.9% salt, L-arginine(L-arg) and LNNA respectively for 2 weeks.The hepatic encephalopathy in cirrhotic rats were induced by 3 mg/kg LPS (ip) 4 hours before the rats were sacrificed. RESULTS: The normal behaviors and electroencephalograph were appeared in L-arg group. LNNA group showed hepatic encephalopathy. The content of NO-_2/NO-_3 of brain tissue was markedly higher in L-arg group than LNNA group(P
