Objective To investigate the efficacy and safety of long guidewire exchange technique in performing cerebral angiography via radial artery approach.Methods The clinical data of 257 patients,who received cerebral angiography during the period from June 2014 to May 2016 at Daxing Hospital of Capital Medical University,Beijing,China,were retrospectively analyzed.Among the 257 patients,186 had type Ⅱ or type Ⅲ aortic arch.According to the different looping technologies for Simmons-2 catheter used in the performance of cerebral angiography,these 186 patients were divided into the study group (n=90) and the routine group (n=96).The success rate of radial artery puncturing,the success rate of Simmons-2 catheter looping formation,the success rate of supra-arch arterial catheterization,the time spent for angiography,the radiation exposure time,complications,etc.were recorded.Results The success rate of radial artery puncturing was 100% in both groups.The success rate of Simmons-2 catheter looping formation in the study group was 97.8%,which was significantly higher than 72.9% in the routine group (P<0.05).The success rates of catheterization for the left subclavian artery,left common carotid artery and right carotid artery in the study group were 97.8%,97.8% and 97.8% respectively,which were remarkably higher than 72.9%,72.9% and 72.9% respectively in the routine group (P<0.05).No statistically significant difference in the success rates of catheterization for right subclavian artery and for right vertebral artery existed between the two groups (P> 0.05).The time spent for angiography in the study group and the routine group was (22.5±9.4) min and (28.3±8.3) min respectively.The radiation exposure time in the study group was (8.9±4.5) min,which was obviously lower than (12.6±6.5) min in the routine group (P=0.017 and P=0.035,respectively).The incidences of complications in the study group and the routine group were 4.4% and 5.2% respectively,the difference was not statistically significant (P>0.05).No severe complications,such as intracranial arterial embolie events,puncture bleeding,arterial occlusion,etc.,occurred in all patients of both groups.Conclusion The use of long guidewire exchange technology can improve the success rate of Simmon-2 catheter looping formation and the success rate of supra-arch arterial catheterization,it can also shorten the time for angiography procedure and reduce the radiation exposure time.This technique is very effective with higher safety.Therefore,this long guidewire exchange technique should be used as a common method for cerebral angiopraphy via radial artery approach in patients with type Ⅱ or type Ⅲ aortic arch.

Objective To study the effect of Atorvastatin on the level of serum high-sensitivity C-reactive protein(hs-CRP) and nitric oxide(NO) in patients with acute cerebral infartion(ACI). Methods 60 patients with ACI were randomly divided into the Atorvastatin therapy group (n=30) and the conventional therapy group (n=30). At the basic of conventional therapy, the Atorvastatin therapy group was treated with Atorvastatin 20 mg/d. Both groups were treated for 14 consecutive days. The levels of serum hs-CRP and NO were measured and the scores of neurological deficit (NDS) were evaluated before and after treatment. Results The levels of serum hs-CRP in both two groups after 14 d treatment were significantly lower than those before treatment ( all P

The efficacy of hematological tumor drugs has shown inter-patient variability. Pharmacogenomics focuses on gene polymorphisms of drug metabolizing enzymes, drug transporters and therapeutic targets and its impact on pharmacokinetics (PK)/pharmacodynamics (PD). Initial dose and adverse reaction can be predicted based on inherited gene polymorphisms, and therapeutic drug monitoring (TDM) also helps to adjust drug dosage in the course of treatment. Thus can achieve rational drug use and personalized medicine, and improve the efficacy and reduce the incidence of adverse drug reactions. This article will introduce the relevant research progress in recent years, and the concept of personalized medication fingerprints is proposed.

Background and purpose: Since the detection of localized prostate cancer is increasing, it's important to distinguish from benign lesions like prostatitis. This study aimed to compare diffusion weighted imaging with apparent diffusion coefifcients in differential diagnosis of localized prostate cancer on 3.0T MR. Methods:Sixty-nine cases with localized prostate cancer proved by pathology, 43 in perpheral zone (PZ) and 26 in central gland (CG), 33 with prostatitis, and 37 with benign prostatic hyperplasia (BPH) were analyzed. The signal noise ratio (SNR) and apparent diffusion coefifcient (ADC) value of lesions were measured, and a semiquantitative grading of DW image was performed. The diagnostic accuracy of both methods was evaluated by ROC. Results:45 cancer foci and 36 prostatitis lesions in PZ, 27 cancer foci and 42 BPH lesions in CG were included. The sensitivity and speciifcity for ADC value to distinguish cancer from begin lesions in PZ and CG were 88.9%and 86.1%、81.5%and 73.8%respectively. The diagnostic accuracy of ADC value was higher than DWI semiquantitative grading and SNR (P<0.05). Conclusion:ADC value yielded a higher accuracy in differential diagnosis of localized prostate cancer on 3.0T MR, thus it’s recommended as a major index for diagnosis.

Objective To observe the clinical effect of manipulation combined with McKenzie technique on discogenic low back pain. Methods 80 patients were randomly divided into control group (n=39, 1 case was lost) and observation group (n=40). The patients in obser-vation group received manipulation and McKenzie technique, while the control group received manipulation only. All the patients were eval-uated with Oswestry Disability Index (ODI), Visual Analogous Scale (VAS) and Self-rating Depression Scale (SDS) before and 3 weeks af-ter treatment. Results The scores of ODI, VAS and SDS decreased after treatment in both groups (P<0.01). The score of ODI and VAS were lower in the observation group than in the control group (P<0.05), while there was no significant difference in the score of SDS between two groups after treatment (P>0.05). Conclusion Manipulation combined with McKenzie technique is more effective on discogenic low back pain.

Objective To investigate the correlation between regional cerebral oxygen saturation (rSO2) value and the prognosis of comatose patients in the intensive care unit (ICU).Methods From January 2013 to September 2014, a total of 64 comatose patients admitted in the department of ICU were enrolled.The patients were divided into two groups : consciousness group (n =25) and coma group (n =39).The level of the Glasgow coma scale (GCS), APACHE Ⅱ score and Full Outline of UnResponsiveness score (FOUR) of patients were monitored.The rSO2 was measured by Somanetics INVOS 5100 monitor.Results The differences in levels of FOUR and GCS at admission and GCS at discharge between the two groups were statistically significant (P < 0.05).In the consciousness group, the levels of GCS、 FOUR and rSO2 were higher compared with the coma group (P < 0.05).ROC curve analysis revealed that the areas under the curve of GCS, FOUR and rSO2 for predicting prognosis were 0.823 (0.718-0.928), 0.820 (0.728-0.912) and 0.924 (0.863-0.985) respectively.Conclusions The rSO2 was useful for estimating the prognosis of comatose patients in general ICU.
