Objective To explore the usefulness of enhanced patient education in increasing the patients' knowledge and awareness of peripherally inserted central catheter (PICC) protection.Methods Totally 200 patients with PICC in Neijiang First People's Hospital from June 2009 to June 2012 were divided into control group (odd numbers,conventional patient education,n =100) and observation group (even numbers,enhanced patient education,n =100) according to their admission numbers.The patients' knowledge and awareness of PICC protection were analyzed after treatment,and the incidences of adverse events and catheter indwelling time were also compared between these two groups.Results Compared with the control group,the observation group had significantly higher PICC protection knowledge rate (91％ vs.78％,P =0.001),awarehess rate (95％ vs.80％,P=0.011),lower incidence of adverse events (1％ vs.5％,P =0.034),and longer PICC indwelling time [(125.8 ± 10.6) d vs.(106.7 ±8.2) d,P =0.026].Conclusion Enhanced patient education can effectively enhance the patients' knowledge and awareness of PICC protection.

The immunopathogenesis of IgA vasculitis and IgA nephropathy both demonstrate IgA deposition,and abnormal glycosylation of IgAl molecule is their major pathogenesis.Therefore,it is clinically controversial that they are actually one disease.The present text will delineate their similarities and differences from aspects of epidemiology,clinic,pathology,mechanism and prognosis.

In recent years,it is a tendency to substitute acute kidney injury (AKI) foracute renal failure (ARF)in the aspect of international nephrology and emergency medicine.Compared with the past,the causes for AKI in children at present has been transferred from primary kidney disease to multi-factors,moreover,the morbidity and mortality of AKI is staying at a high level.From the perspective of epidemiology this paper briefly analyses the common cause,mortality and morbidity of AKI in children.

Objective:To study the effect of the three kinds of EE on the cognitive function and the expression of SYN and MAP-2,and the dentritic growth of pyramidal cells of the cerebral cortex in rats.Method:Forty-eight male SD rats were divided into preserving the physique EE group (EE1),preserving the spirit EE group (EE2),preservation for both physique and spirit EE group(EE3) and standard group (SE),12 rats in each group.Rats were put into the three kinds of EE or standard cages after pre-training.The environmental enrollment lasted for 14 days and followed by a 6-days Morris water maze test.After the Morris water maze test,all the rats were sacrificed for histological study,including using the immunohistochemistry method to detect the expression of SYN and MAP-2,and using the Golgi-Cox staining to study the dentritic growth of pyramidal cells in cerebral cortex.Result:In the Morris water maze,the EE3 group exhibited shorter escape latency than the MCAO+SE group (P＜0.05) on day 5,while no significant differences were seen for the time spent in the target quadrant among the 4 groups (P＞ 0.05).The results of immunohistochemical staining of SYN showed that the expression of SYN was the lowest in the SE group,and there was no significant difference between EE1 and EE3 groups but significantly higher than the EE2 group.The expression of MAP-2 was the lowest in the SE group,and there was no significant difference of expression between EE1 and EE2 groups but significantly lower than the EE3 group.The results of Golgi-Cox staining showed that there was no difference of the dentritic branch among groups in mPFC (P＞ 0.05) while the spine density of the EE1 group was significantly greater than that of the SE and EE2 groups (P ＜ 0.05),but significantly lower than that of the EE3 group (P ＜ 0.05).Conclusion:Two weeks of preservation from both physique and spirit EE can improve the cognitive function,and promote the expression of MAP-2 and SYN and the dentritic growth of pyramidal cells in normal rats.

Objective To observe the correlation between nuclear factor ?B(NF-?B) expression and apoptosis after hypoxia-ischemia brain damage(HIBD).Methods Forty-eight 7-day newborn Sprague-Dawley(SD) rats were randomly divided into 2 groups: control group (n=24) and HI group (n=24).The expression of NF-?B in the hippocampus was detected by immunohistochemical techniques.The apoptosis of the hippocampal cells was detected by terminal deoxynucleotidyltransferase-mediated 2-deoxyuridine 5′-triphosphate-biotin nick end labeling(TUNEL)straining.Results The expression of NF-?B in hippocampal cells increased at 6 h after HIBD,peaked at 48 h,and lasted till 72 h when compared with control group(Pa

0.05). (2) The average squeezing anal pressure and the duration of anal squeezing decreased in the experiment group, which were significantly different from those in the control group ( P

Earthquake may result in various urologic problems by direct injury of urologic organs or by spinal cord injury.This article introduces the main urologic problems after earthquake,classified into early and long-term.Such as urinary retention,oliguria or anuria,renal injury,bladder and urethra injury,neurogenic bladder caused by spinal cord injury,et al.We analyze the causes of the problems and discuss the correct management principle,all kinds of rehabilitation measures to reduce the complication and sequela,also the problems should be cautioned during the long term follow-up.

OBJECTIVETo compare the sedative effects of different doses of dexmedetomidine (DEX) and midazolam (MDZ) in dental implant surgery:

METHODSSixty patients undergoing dental implantation were selected and divided randomly into six groups (10 in each group). In group 1 (G1), a highdose of MDZ alone was administered intravenously. In group 2 (G2), a relatively low dose of MDZ and DEX was administered intravenously. In group 3 (G3), a highdose of MDZ and DEX was administered intravenously. In group 4 (G4), a lowdose of MDZ and a highdose of DEX were administered. In group 5(G5), a highdose of MDZ and a low dose of DEX were administered. In group 6 (G6), a highdose of DEX alone was administered intravenously. Blood pressure (BP), heart rate (HR), and arterial oxygen saturation values were measured. Sedation was assessed by determining the Ramsay sedation scores(RSS) during infiltration anesthesia (T1), incision (T2), cutting (T3), and suturing (T4). Before discharging from the hospital, patients were asked if they remembered the T1 to T4 procedures. The visual analogue scale (VAS) and the degree of patient satisfaction were assessed at the same time.

RESULTSIn T1 to T4, the systolic blood pressure (SBP) in G3 was the lowest and was significantly different from that in G1 and G2 (P < 0.05). In G1, the SBP was higher than that in G6 at the T3 and T4 points (P < 0.05). HR was below the preoperative (P < 0.05) in the G3 only. RSS was the lowest in G1 during the whole procedure. In G2, most patients obtained scores of 2-3. In G3, sedation was deeper, had more cases ofup to 5. In G4, most patients obtained scores of 3-4. In G5, some patients had a score of up to 5. The RSS in G6 was lower than that in G3 and G4 or G5 in T1 to T2, closer to G4 in T2. An evaluation of the VAS and the degree of patient satisfaction did not show any differences among the groups.

CONCLUSIONThe combination of DEX and MDZ is superior to a single intravenous injection. Low-dose MDZ combined with high-dose DEX achieved the highest quality of sedation in this study.
