Objective To explore the effect of 3M Tegaderm transparent film on prevention of puncture complications in patients underwent aortocranial angiography via the femoral artery.Methods A retrospective analysis was carried out on 200 patients underwent aortocranial angiography via the femoral artery from February 2012 to February 2014.Eighty patients without using the transparent dressing paste were as the control group,and other 120 patients using 3M Tegaderm transparent film for fixation of arterial sheath were as the observation group.The occurrences of complications,such as arterial sheath breakage,angiographic tube breakage,femoral artery spasm,bruises at the puncture site and subcutaneous hematoma were analyzed,and the feasibility and effectiveness of 3M Tegaderm transparent film for fixation of arterial sheath were assessed.Results The incidence rate of arterial sheath breakage,angiographic tube breakage,femoral artery spasm,bruises at the puncture site and subcutaneous hematoma were significantly reduced in observation group compared with those in control group [5.8％ (7/120) vs.26.2％ (21/80)] (P ＜ 0.05).Conclusion Application of 3M Tegaderm transparent film with a low price and good security for fixation of femoral artery sheath can effectively reduce the occurrence of complications related to femoral artery puncture,which is worthy of wide spreading.

Objective To explore the efficacy and safety of arterial embolectomy with Solitaire AB stent in treatment of acute intracranial large artery occlusion.Methods The clinical data of 11 patients with acute intracranial large artery occlusion receiving arterial embolectomy with Solitaire AB stent from March to December 2013 were analyzed retrospectively.Among them,5 cases were with simple middle cerebral artery occlusion,1 case combined with occlusion in the intracranial part of the internal carotid artery,4 cases had simple basilar artery occlusion,and 1 case had occlusion in the intracranial portion of the vertebral arteries extending to intracranial portion of the basilar artery.Revascularization and postoperative hemorrhage were analyzed,and nosocomial as well as clinical outcomes after 3 months were evaluated.Results Ten patients showed successful revascularization,of which 8 cases reached the standard of perfect revascularization.After embolectomy,there was obvious stenosis in offending vessel of 4 cases,who were given balloon dilatation then.In 3 cases,the vessels were still narrow,so Solitaire AB stent was placed in the stenosis area to correct stenosis with the residual stenosis rate of less than 40％.Thus electrolytic interruption was given.There was no symptomatic intracranial hemorrhage.Three months after the operation,5 cases recovered,among whom 2 cases had obvious curative effect instantly,1 case had complete remissions in 1 week,and 1 case remained hemiplegia.Five cases died,and 4 cases discharged from the hospital because their family gave up the subsequent treatment.Conclusions Arterial embolectomy with Solitaire AB stent to treat patients with acute intracranial large artery occlusion has a relatively higher revascularization rate.The clinical outcome after 3 months can be significantly improved.Thus,it provides a safe and effective endovascular treatment for patients with acute intracranial large artery occlusion.

Background and purpose: The literature on dose-volume parameters and pneumonitis is extensive. The results are inconsistent, both for the best predictive metrics and significant comorbid factors. This study aimed to investigate a prospective functional equivalent uniform dose (fEUD) with perfusion single photon emission computed tomography (SPECT) images as predictors of radiation pneumonitis (RP) in patients undergoing curative radiotherapy (RT). Methods: Functional lung imaging was performed using SPECT for perfusion imaging. Perfusion factors were defined as the mean percentile perfusion levels of the 4 areas, top to 75%, 75% to 50%, 50% to 25%, 25% to 0%, re-spectively. fEUD was calculated from perfusion factors and standard dose-volume parameters extracted from treatment planning computed tomography (CT) scans. Total lung (TL), ipsilateral (IL) and contralateral lung (CL) volumes minus gross tumor volume (GTV), whole-lung V5, V20, whole lung fEUD, IL and CL fEUD, and general equivalent uniform dose (gEUD) were analyzed to evaluate correlations between RP using Common Terminology Criteria for Adverse Events (CTCAE) version 4.03. Statistical significance was defined as P<0.05. Results: A total of 15 patients treated with intensity modulated RT or 3D conformal RT were analyzed, grades≥3 RP were observed in 6 patients. There was only a trend toward significance for unilateral (UL) fEUD of higher dose side (P=0.007). Whole-lung V5, V20 were almost identical between patients who developed pneumonitis and patients who did not, as the values were below the recommended thresholds from published papers. Unilateral fEUDs were linear with unilateral gEUDs (t=0.815, P=0.000). Conclusion: SPECT-based equivalent uniform dose appears to be a better predictor of RP compared to stan-dard dose-volume parameters. Planning constraints should aim to keep unilateral fEUD below 21 Gy.

Objective To investigate the distribution and constituent of drug‐resistant bacteria of lower respiratory tract in‐fection among different regions (outpatient department ,wards ,RICU) to provide the basis for the clinical reasonable application of antimicrobial agents .Methods The K‐B disc diffusion method and the instrument method (VITEK‐TWO) were adopted and the detection results were interpreted according to the standards of CLSI 2010 .The detection data of 480 drug‐resistant strains isolated from the sputum ,branchoalveolar lavage fluid samples submitted in 3 regions of respiratory outpatients department by bacterial cul‐ture identification and drug susceptibility test were analyzed by using the WHONET5 .6 statistical software .Results The distribu‐tion and constituent of drug‐resistant bacteria of lower respiratory tract infection had obvious difference among 3 different regions . The top 4 of drug resistant bacteria were dominated by Gram‐negative bacteria .The drug resistance rate of Klebsiella pneumoniae in RICU was higher than that in the respiratory outpatients department and wards(P<0 .05) ,the resistance rate in the respiratory outpatients department ,wards and RICU to commonly used antibacterial drugs was similar;the multiple drug resistance of ESBLs‐producing strains was obviously higher than that of non‐ESBLs‐producing strains (P<0 .05) .Pseudomonas aeruginosa maintained the higher antibacterial activity to quinolone ,aminoglucosides ,cefepime ,imipenem ,cefoperazone/sulbactam ,and piperacillin/tazobactam ,but the resistance rate in RICU was significantly higher that in the respiratory outpatient department and wards (P<0 .05);the drug resistance of Acinetobacter baumanii in the respiratory wards and RICU was higher than that in the respiratory out‐patient department ,the resistances to imipenem were 64 .6% and 70 .4% respectively .The resistance of MRSA to rifampin in RICU was higher than that in the respiratory outpatient department and wards(P<0 .05) .Conclusion The distribution constituent and drug‐resistance rates have obvious differences among the respiratory outpatient department ,wards and RICU .Except being familiar with the drug resitant bacterial distribution and drug resistance rate monitoring situation ,clinical doctors should grasp the drug re‐sistance situation of drug resistant bacteria among different areas in various departments of own unit in order to rationally and effec‐tively use antibacterial drugs .

Objective To evaluate the clinical efficacy of the local drug resistance spectrum antibiotics and foreign guideline in the treatment of patients with community acquired pneumonia(CAP). Methods A prospective,randomized,single blind,and positive drug parallel controlled design was used in the treatment. CAP patients with no underlying disease outpatients and inpatients<48 hours were selected as the research object. The patients in the trial group were given sensitive local drug resistance spectrum antibiotics: moxifloxacin,400 mg and 1 times a day. The patients in the control group were given azithromycin tablets(each 500 mg,once daily) promulgated by the 2007 version of the IDSA / ATS adult CAP guideline. Results There were 106 cases of CAP patients,of which 77 cases completed treatment,including 39 cases in the experimental group and 38 cases in the control group. There were significant differences in the clinical efficacy and bacterial clearance rate between the two groups,with the clinical efficacy of 89.7% and 68.4%(P < 0.01),the bacterial clearance rate of 87.9% and 54.5%(P < 0.05),respectively. Conclusion The clinical efficacy of drug resistant spectrum sensitive antibiotics in the treatment of CAP in Kunming was better than that of IDSA/ATS. Clinicians should pay attention to the characteristics and composition of resistance of common pathogenic bacteria in our country during the study and reference from foreign guideline,and adjust the therapeutic regimen according to the changes of the local drug resistance monitoring data rather than copy the recommended treatment plan by foreign countries.

OBJECTIVETo test the effect of sulindac on autistic behaviors in a rat model and explore the possible mechanisms.

METHODSAutistic rat models were established by a single intraperitoneal injection of sodium valproate (VPA) at 12.5 days of pregnancy. The pregnant rats were treated with oral sulindac at a daily dose of 80 mg/kg until weaning of the newborn rats (23 days after being born), which were divided into control, VPA treatment, sulindac treatment, and VPA+ sulindac treatment groups. The social interaction and neuroethology of the newborn rats were evaluated at 35 days, and the levels of β-catenin and phosphorylated Gsk3β in the brain tissues were investigated by Western blotting.

RESULTSCompared with the control rats, the rats treated with VPA showed lower social interaction, longer moving time in central area, and reduced standing times. Treatment with sulindac alone resulted in no obvious changes in the social interaction or neuroethology of the newborn rats, but sulindac treatment corrected VPA-induced autistic-like behaviors. Sulindac also attenuated VPA-triggered p-Gsk3β downregulation and β-catenin upregulation in the prefrontal lobe, seahorse and cerebellum.

CONCLUSIONSulindac can improve the behaviors of autistic rats possibly by suppressing Wnt signaling pathway.
