ObjectiveTo explore the causes and countermeasures for extravasation of intravenous fluids in children. Methods726 cases of intravenous infusion in pediatric surgery department from May to December 2011 in our hospital were observed. ResultsThere were 30 cases with extravasation of intravenous infusion in the 726 cases,the leakage rate was 4.13％.The specific causes of fluid extravasation included:younger age of children,not cooperating with the infusion in 18 cases,accounting for 60.00％,followed by non standardized fixation methods in 5 cases,accounting for 16.67％,and accompanying family members refused to be disturbed accounted for 13.33％,Nursing visits to owe in a timely manner accounted for 6.67％.The rate of younger age of children and lack of cooperation leading to fluid extravasation were significantly higher than other causes,the difference was statistically significant. ConclusionsChildren age,fixation method,cooperation of family members,inspections and other factors can be controlled.Along with the continuous improvement of medical standards and a variety of active and effective implementation of the measures,these factors can be controlled effectively.Strengthening the training of nurses and vocational skills to enhance their own sense of responsibility,to give standardized infusion operation and fixation,and give predictable observation and treatment,can effectively prevent the occurrence of extravasation of intravenous fluids.

Objective To explore the role of remote ischemic preconditioning(RIPC)in prevention of contrast -induced nephropathy(CIN)in elderly patients undergoing coronary artery angiography(CAA).Methods 106 elderly patients were enrolled in this randomized control trial.According to random number table,the patients were randomized into control group (n =53)and RIPC group(n =53).All of the patients received 1 000mL of 0.9% sodium chloride injection before CAA.The RIPC group patients underwent RIPC in their right arms with sphygmomanometer cuff infla-tion for 5 minutes prior to the CAA,three cycles were repeated.Serum creatinine was detected before and 48 hours after CAA.Results CIN was reported in 10 cases in the control group and 3 cases in the RIPC group(χ2 =4.30, P =0.04).The levels of serum creatinine were increased[(96.38 ±9.50)μmol/L vs (88.87 ±10.24)μmol/L] after CAA in the control group(t =2.28,P =0.03),and there was no difference in the RIPC group(t =1.17,P =0.24).Conclusion RIPC has a protective effect on CIN in elderly patients in our study.Since this method is harm-less and cost effective,further studies is required to popularize PIPC to our clinical practice for prevention of CIN.

Objective To investigate the clinical results of immediate loading of a single anterior implant. Methods 26 implants were placed into anterior sites. Provisional prosthesis were placed at the time of fixture placement. It did not occlude in any pathway. Restoration was for esthetic only, not for function. Results No fixture was lost since the immediate restoration was delivered, the minimum being 12 months and the maximum 72 months. Conclusion Clinical studies on the placement of immediate restoration in anterior implant of maxilla have revealed predictable results.

Objective To analyze the related factors of nursing risk in department of nephrology and to explore strategies of risk management.Methods Risk management was implemented to 39 nurses in department of nephrology of our hospital.The KAP scores,the incidence of nursing risk events,nursing complaints and patients' satisfaction degree before and after the implementation of nursing risk management were compared.Results After the implementation of nursing risk management,nurses' KAP score was significantly higher; the incidence of nursing risk events and complaints significantly reduced; patients' satisfaction degree to nursing were significantly higher compared with those before the implementation.Conclusions The implementation of nursing risk management can effectively improve the quality of nursing and reduce the incidence of nursing risk events.

Objective To explore the relationship between human papilloma virus (HPV) infected population and disease occur‐rence in order to provide evidence and some reasonable suggestions for people understanding this disease .Methods A total of 2 508 suspected patients in our hospital from August 2012 to August 2013 were performed the HPV subtype detection by using PCR‐re‐verse dot blot(RDB) ,including 18 kinds of high risk HPV subtypes(HPV16 ,18 ,31 ,33 ,35 ,39 ,45 ,51 ,52 ,53 ,56 ,58 ,59 ,66 ,68 ,73 , 83 ,MM4) and 5 kinds of low risk HPV subtypes (HPV6 ,11 ,42 ,43 ,44) .Finally ,the patients condition was tracked through the hospital information management system and the clinical laboratory information systems .Results The HPV detection rate was 12 .26% ,in which the high risk type was mainly HPV 52 ,accounting for 12 .66% ,followed by HPV 58 ,16 .The low risk types were mainly HPV 43 ,6 ,11 ,accounting for 14 .61% ,10 .39% and 8 .44% respectively .By the follow up observation of clinical outcomes , the homotype positive phenomena were repeatedly appeared in the patients infected by HPV 52 ,16 within 2 years .At the same time ,the thinprep cytologist test(TCT) results in 157 cases of high risk HPV infection (genotype 52 ,58 ,16 ,18 ,66 ,33 ,56 ,68) were performed the tracking analysis ,indicating that high risk HPV infection was closely associated with cervical intraepithelial ne‐oplasia (CIN)Ⅰ ,CIN Ⅱ and canceration .Meanwhile ,their leucorrhea routine detection were followed up ,which manifested by mild to moderate inflammation .Conclusion High risk HPV subtype infection is closely associated with CIN Ⅰ ,CIN Ⅱ and canceration , while the leucorrhea routine shows mild ,moderate inflammation .Therefore ,only conducting the simple leucorrhea routine analysis can not really reflect the infection status ,it is necessary to look for the ways to cooperate with the superior hospital for timely detec‐ting HPV infection situation ,moreover regular follow up of people with HPV positive is the effective pathway to prevent CIN and cervical cancer .

Because of hardness to heal and easiness to recurrence,chronic ulcer of lower limp has become one of the hardest diseases in clinic,which brings physical and mental pain to the patients.Although medical technology develops rapidly,to find a simple,effective and economic method is still the focus.Here,progress and current situation of treatment were summarized for chronic ulcer of lower limp.

OBJECTIVE To explore the phenotype and genotype of Klebsiella and Escherichia coli producing extended-spectrum ?-lactamases(ESBLs).METHODS The producing ESBLs strains in 110 E.coli and 94 Klebsiella isolates were determined according to disk diffusion test,recommended by NCCLS and the drug-resistant genes such as TEM,SHV,CTX-M-1,CTX-M-2 and CTX-M-9 were detected by PCR and sequencing.RESULTS The producing ESBLs rates were 36.2%,42.7% and 39.7% in Klebsiella,E.coli,and in both two strains,respectively.The positive rate in detecting ESBLs by CTX and CTX/CLAV was higher(66.7%);the negative rates were 68.1% in E.coli,64.7% in Klebsiella when using CAZ alone and CAZ/CLAV.The rates of TEM,SHV,CTX-M-1,CTX-M-2 and CTX-M-9 were 54.3%,38.3%,21.0%,24.7% and 70.4%,respectively,in producing ESBLs isolations.The CTX-M genotype was predominant,(91.4%);the isolations(71.6%) contained more than two resistance genes.CONCLUSIONS More attention should be payed on ESBLs producing E.coli and K.pneumoniae strains.

Objective To investigate the drug-resistance of Staphylococcus aureus induced by erythromycin in vitro and its changes in growth and susceptibility of antibiotics.Methods Erythromycin in vitro induction was conducted with the S.au-reus reference strain ATCC25923 on the serial of erythromycin agar plates.The growth of S.aureus,and the susceptibility a-gainst other antibiotics was compared after induced to the parent strain.Results Resistance to erythromycin was successful-ly,and themaximum MIC was over 256 mg/L.The Erythromycin-resistant S.aureus grew much slower than the susceptible parent,and the strains didn’t have cross-resistance to other antibiotics.Conclusion S.aureus could be induced resistance in vitro by erythromycin,and this resistance inherited stably.Some phenotype and biochemical characteristic features of the strain were changed after induced.
