Chinese Journal of Practical Nursing 2016;32(17):1330-1333
Objective To investigate the profession development status of intra-veineuse (IV) nurse team in Anhui province, provide the reference and baseline data on intravenous therapy management of province unity standard. Methods Using the cluster sampling method, the questionnaire designed by IV professional committee of Anhui province was used to investigate the status of IV nurse team in 137 hospitals. Results IV nurse in 35 hospitals (25.6%) was accepted the intravenous treatment knowledge training, however no specific provision for training time in 91 hospitals (66.4%). Organization in PICC evaluation was diversified, such as manufacturer (40 accounted for 29.2%), nursing association in province (city)( 38 accounted for 27.7%) and nursing department in hospital (36 accounted for 26.3%). 28 hospitals had PIVAS (20.4%). 62 hospitals established IV nurse team (45.3%), 87 hospitals established IV quality control system (63.5%). Implementation strength was good in the special inspection, the following feedback in standardized operation and adverse events (81 accounted for 59.1%, 72 accounted for 52.6%and 75 accounted for 54.7%, respectively), however, there was no enough emphasis on regular meeting, organization consultation and collection data of regular basis (59 accounted for 43.1%, 52 accounted for 38.0%and 32 accounted for 23.4%, respectively). Conclusions IV nurse team has been preliminarily established in Anhui province, however there are some problems, for example, specialist nurse training and examination is not unified, overall quality control system have not established, external conditions need to be improved. Related departments should actively formulate corresponding countermeasure to promote the healthy development of the IV nurse team.

Objective To investigate the effects of ultraviolet irradiation on the morphology, cell proli-feration, mutation frequency and level of expression of ATP mRNA in human fibroblasts. Methods The infant foreskin fibroblasts were cultured and irradiated with different doses of ultraviolet A or B (UVA or UVB). Light microscopy was used for observing the morphologic change and cell counting of cell proliferation, HPRT-mutagenesis assay for the mutation detection, and RT-PCR for the expression of ATP mRNA. Results Compared with the control group, the irradiated cultured fibroblasts were damaged, cell growth was retarded (MTT assay showed 2.4 fold increase in the control group but only 0.2 fold in the UVB group 72 h after irradiation). Mutation frequency in 106 colony forming cells was increased from 20.4 ? 6.7 at 20 mJ/cm2 to 97.7 ? 7.1 under 60 mJ/cm2 of UVB irradiation. The expression level of ATP mRNA was down-regulated after UV irradiation. There was an increase of mutation frequency which was UVB dose-dependenct, and decrease of ATP mRNA expression which was dose- and time-dependent. Conclusions After UV irradiation of the cultured fibroblasts, the cell damage and growth inhibition are induced, and the mutation frequency is increased in a UVB dose-depen-dent maaner. The expression of ATP mRNA shows down-regulation in both dose- and time-dependent manner.

Background and purpose:The traditional 3 incision surgery is an important means of esophageal cancer treatment, however, accompanied by more postoperative complications and higher mortality. Minimally invasive esophagectomy is a prospective technology with advantages, such as little trauma and quick recovery. This study retrospectively analyzed the perioperative effect of the esophagus cancer patients who accepted thoracoscopic-laparoscopic esophagectomy (TLE), open-laparoscopic esophagectomy (OLE) and open esophagectomy (OE) from Jan. 2013 to Jan. 2015. Methods:In this study, 72 patients received TLE, 76 patients received OLE and 115 patients received OE, respectively. One-way ANOVA, Kruskal Wallis test and Chi-square test were used to compare the differences of general clinical data, perioperative recover index, the number of lymphadenectomy and the postoperative complication among TLE, OLE and OE. Results:There were differences in the area of operative blood loss, duration of ICU stay and first standing time among the 3 groups. Pairwise comparison demonstrated that TLE group was signiifcantly better than OE group (P<0.012 5). The total number of lymphadenectomy among the 3 groups had no differences. However, the number of lymph node of the upper esophagus in the TLE groups was more than those in OLE group and OE group (P<0.001). The laryngeal recurrent nerve injury incidence in TLE group was signiifcantly higher than those in OLE group and OE group (P=0.012, 0.003). The total surgical complication had no differences among 3 groups. In areas of the cardiorespiratory system severe complication, 3 groups had statistical differences. Pairwise comparison showed TLE group was significantly less than OLE and OE group (P<0.0125). The first day and third day incidences of SIRS rate in TLE group were less than those in OLE group and OE group (P<0.0125). Conclusion:Comparing to OE group, with the same safety and feasibility, TLE had more advantages such as trauma, quick recovery, less complications. With the same effect of total lymphadenectomy to OE, TLE had the more advantage in upper mediastinal and recurrent laryngeal nerve lymph node cleaning.
