Objective To investigate the construction of PICC catheterization nurses in Shandong province. Methods A total of 235 hospitals were investigated from PICC maintenance network in Shandong province with self-designed questionnaire through internet survey. Results 179 hospitals established intravenous (IV) nurse team(76.17%). 86.92%(93/107) of the tertiary hospitals established Ⅳ nurse team, which was higher than 67.19% (86/128) of the secondary hospitals, the difference was statistically significant(χ2=12.50,P<0.01). There were 1335 trained and certificated nurses while 1382 nurses engaging in PICC catheterization, and there were more PICC catheterization nurses in tertiary hospitals than secondary hospitals, the difference was statistically significant(t=7.23,P<0.01). 22.98%(54/235) of the hospitals had more PICC catheterization nurses than trained and certificated nurses, 11.49%(27/235) of the hospitals had more trained and certificated nurses than PICC catheterization nurses. 7.81%(108/1382) of the PICC catheterization nurses worked full-time and 31.91%(441/1382) had a manager position. 51.06% (120/235) of the hospitals had set up clear selection criteria for PICC catheterization nurses, mainly focusing on education background, professional tittle and (or) work experience. Organization in PICC training was diversified, giving priority to nursing association in provinceand nursing association in city. PICC catheterization nurses in only 20.43% (48/235) of the hospitals would accept training annually, 31.49%(74/235) of the hospitals would re-certificate PICC nurses. Conclusion PICC nurse team has been preliminarily established in Shandong province, but nursing staff deployment was unevenness, and primary hospitals should be further reinforced. The position role of PICC nurses should be further clarified. The selection criteria of PICC nurses should be further standardized. And the training space of PICC nurses should be further promoted.

Objective To investigate the current status of healthcare-associated infection (HAI),community-associated infection(CAD,and antimierobial use in hospitalized patients in medical institutions of Guizhou Province.Methods In September 2014,infection status of hospitalized patients in 174 second level hospitals and above in Guizhou Province were performed cross-sectional survey.Results A total of 68 419 patients were surveyed,the actual survey rate was 99.65％.1 581 patients developed 1 684 cases of HAI,HAI prevalence rate and HAI case prevalence rate were 2.31％ and 2.46％ respectively,18 571 patients developed 19 191 cases of HAI,CAI prevalence rate and CAI case prevalence rate were 27.14％ and 28.05％ respectively;patients in general intensive care unit(ICU) and pediatric department(non-neonatal group) had the highest HAI and CAI prevalence rates respectively.Constituent ratios of HAI and CAI sites was significantly different(x2 =17 325.44,P＜0.01);Escherichia coli was the main pathogen causing HAI and CAI.Utilization rate of antimicrobial agents on the survey day was 39.82 ％,ICU (80.47 ％) and pediatric department (76.67 ％) were the highest.Therapeutic antimicrobial use accounted for 67.48 ％ (n =18 386),single antimicrobial use accounted for 79.55 ％ (n =21 672).Pathogenic detection rate of specimens from patients receiving therapeutic antimicrobial agents was 31.76％.Conclusion This survey is helpful for understanding the high risk departments and sites of HAI and CAI in Guizhou Province,as well as pathogenic detection rate of specimens from patients receiving therapeutic antimicrobial agents,which provides basis for further prevention and control of HAI.

ObjectiveTo evaluate the role of p38MAPK signaling pathway in the up-regulation of heme oxygenase-1 (HO-1) expression in the lung tissue in rats with acute lung injury (AL1) induced by endotoxic shock.MethodsForty-eight male SD rats,aged 8 weeks,weighing 180-200 g,were randomly divided into 4 groups ( n =12 each):control group ( group C ) ; endotoxic shock group ( group LS );endotoxic shock +SB203580 (a specific p38MAPK inhibitor) group (group LSS) and SB203580 group (group SB).Normal saline 0.5ml was injected via the femoral vein in groups C and SB,while LPS 10 mg/kg (in 0.5 ml normal saline) was injected via the femoral vein in groups LS and LSS.When MAP was decreased to 75％ of baseline value,10％ dimethyl sulfoxide (DMSO) 0.1 ml was infused via the femoral vein in groups C and LS,while SB203580 5 mol/kg (in 10％ DMSO 0.1 ml) was infused via the femoral vein at a rate of 0.01 ml/min in groups LSS and SB.Arterial blood samples were obtained at 6 h after LPS or normal saline was given for blood gas analysis and oxygenation index (PaO2/FiO2) was calculated.Then the rats were sacrificed and the lungs were removed for microscopic examination.The pathological changes of the lung were scored.The lung water content was calculated.The MDA content,SOD activity,and expression of HO-1 mRNA and protein,p38MAPK protein and phospharylated p38MAPK (p-p38MAPK) protein were determined.ResultsCompared with group C,the oxygenation index and SOD activity were significantly decreased,the pathological score,lung water content and MDA content were significantly increased,and the expression of HO-1 mRNA and protein and p-p38MAPK protein was significantly up-regulated ( P＜0.05),while no significant change was found in p38MAPK protein expression in groups LS and LSS,and no significant change was found in the indexes mentioned above in group SB (P＞0.05).Compared with group LS,the oxygenation index and SOD activity were significantly increased,the pathological score,lung water content and MDA content were significantly decreased,the expression of HO-1 mRNA and protein was significantly up-regulated,and p-p38MAPK protein expression was down-regulated ( P＜0.05),and no significant change was found in p38MAPK protein expression in group LSS ( P＞0.05).ConclusionThe inhibition of p38MAPK signaling pathway can lead to the up-regulation of HO-1 expression in lung tissues in rats with ALI induced by endotoxic shock.

In this study, SD rats were orally administrated with oteracil potassium (300 mg . kg-1 . d-1 ) to prepare the hyperuricemia model, and divided into normal, model, Allopurinol, LE high dosage, middle dosage and low dose (200, 100, 50 mg . kg-1 . d-1) groups. The rats were orally administrated with test drugs 1 hour later after being orally administrated with Oteracil potassium. After 7 days, serum uric acid, serum creatinine, uric acid and expression of relevant transporters in kidney were tested to study the regulatory effect of leonurus extracts on serum uric acid, renal function and relevant transporters in kidney of rats with hyperuricemia. Compared with the model group, the leonurus extract group could significantly down-regulate serum uric acid and creatinine levels of rats with hyperuricemia, and increase the urine uric acid level. Meanwhile, leonurus extracts could notably down-regulate the mRNA expressions of urate transporter 1 (URAT1) and glucose transporter 9 (GLUT9), up-regulate the mRNA expressions of organic cation transportanter (OCT) and Carnitine transporter (OCTN) and promote the excretion of uric acid of kidney.
