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 investigate the expression of pro-inflammatory cytokines in lumbar dorsal root ganglions (DRG) of rats model of high-dose fentanyl induced hyperalgesia. Methods 64 male SD rats were divided into 2 groups (n = 32), fentanyl group and normal saline (NS) group. The rats were injected with fentanyl (60 μg/kg) or NS 4 times in total subcutaneously with a 15-minute interval. Mechanical and thermal nociception were measured via the tail pressure test (tail flick thresholds, TFT) and paw withdrawal test (paw withdrawal latency, PWL) at 1 day before, at 1, 2, 3 and 4 hour and on 1 ~ 7 day after administration. 4 rats were sacrificed and the lumbar DRG were harvested to analyze the expression of PGE2 , IL-1β, IL-6 and TNF-αvia ELISA. Results There were no significant changes of TFT, PWL and the expression of pro-inflammatory cytokines in DRG compared to baseline of rats in NS group. The value of TFT , PWL in fentanyl group were above the baseline at the 1 ~ 4 hour and below the baseline at 1~3 day after fentanyl injections. PGE2 , IL-1β, TNF-α and IL-6 increased on 1,3,5,7 day after fentanyl injections significantly. Conclusions High-dose fentanyl induced significant hyperalgesia and up-regulation of pro-inflammatory cytokines in DRG. The expression pro-inflammatory cytokines peaked later and were more protracted than the change of behavior test and show no direct relationship between the two.

Objective To investigate the outcomes of increased gestational diabetes mellitus (GDM) and the influencing factors after the implementation of the new GDM diagnostic criteria.Methods A total of 1 439 GDM women who delivered in the Peking University First Hospital between May 1,2011 and December 31,2012 were studied and divided into two groups.Group Ⅰ included the women who met the new GDM diagnostic criteria (fasting plasma glucose and 1 or 2 h plasma glucose levels for 75-g oral glucose tolerance test performed between 24 and 28 weeks of gestation were no less than 5.1,10.0 and 8.5 mmol/L),but did not meet the National Diabetes Data Group (NDDG) criteria;and Group Ⅱ included the women who met the NDDG criteria only.Women in Group Ⅰ were further divided into two subgroups according to whether attending the one-day GDM outpatient visit.Follow-up rate and detecting rate of abnormal glucose metabolism at 6-12 weeks after delivery were analyzed.Chi-square test,t test and multivariate Logistic analysis were used for statistical analysis.Results There were 849 GDM women in Group Ⅰ (59.0％,849/1 439) and 590 (41.0％,590/1 439) in Group Ⅱ.The follow-up rate in group Ⅰ was lower than in group Ⅱ [25.9％(220/849) vs 32.0％(189/590),x2=6.112,P=0.013].There were five cases of impaired fasting glucose and 34 impaired glucose tolerance in Group Ⅰ;and four cases of impaired fasting glucose,56 impaired glucose tolerance,eight impaired fasting glucose tolerance with impaired glucose tolerance and five diabetes mellitus in Group Ⅱ;there were significant differences [17.7％(39/220) vs 38.6％(73/189),x2=33.810,P=0.000].(2) In Group Ⅰ,the increased glucose level at 2 h in oral glucose tolerance test during pregnancy (OR=1.547,95％CI:1.038-2.306,P=0.032) and family history of diabetes mellitus (OR=1.879,95％CI:1.066-3.313,P=0.020) were risk factors for postpartum abnormal glucose metabolism,while breast-feeding was a protective factor (OR=0.290,95％CI:0.092-0.914,P=0.035).(3) In group Ⅰ,the follow-up rate in those who attended the one-day GDM outpatient visit was higher than those who did not [30.7％(185/603) vs 14.2％(35/246),x2=23.780,P=0.000],but the detecting rate of postpartum abnormal glucose metabolism were similar in women attending the one-day GDM outpatient visit and those not attending [17.8％(33/185) vs 17.1％(6/35),x2=0.020,P=0.887].Conclusions Increased GDM women still have glucose metabolism abnormality after delivery,especially those who have higher glucose level at 2 h after glucose intake in 75 g oral glucose tolerance test during pregnancy and who have a family history of diabetes mellitus.The one day GDM outpatient visit may improve the follow-up rate for these women.

Objective To evaluate the impact of epidural anesthesia with levobupivacaine combined with general anesthesia on colon surgery. Methods Sixty patients undergoing elective radical procedure for colon carcinoma were randomLy divided into four groups: saline group (group S), 0.125% levobupivacaine group (group L1), 0.25% levobupivacaine group (group L2), and 0.5% levobupivacaine group (group L3). Group S received normal saline of 10 mL epidurally and then infusion of 5 mL·h-1 until the procedure was finished; groups L1, L2, and L3 received levobupivacaine instead. Anesthetic induction was performed after epidural puncture. Mean blood pressure and heart rate were recorded at 8 time points including 5 min after entering into the operation room, 1 min after intubation, skin incision, abdominal exploration, 1 h after skin incision, completion of operation, extubation, and leaving PACU; meanwhile blood glucose and cortisol were detected, anesthesia time, time to PACU stay, bleeding, transfusion volume, adverse reaction, and doses of propofol, remifentanil, ephedrine, and fentanyl were noted. Results Time to PACU stay was longer in S group than in other 3 groups. Doses of remifentanil and fentanyl were larger in L1 group than in L2 group and L3 group. Ephedrine dose in L3 group was larger than in other 3 groups. Blood sugar in L1 group was higher than L2 group and L3 group. Cortisol in S group was higher than in other 3 group. Cortisol in L1 group was higher than in L3 group. The number of patients with hypotension was greater in L3 group than other 3 groups. Conclusions Continue epidural infusion of 0.25%levobupivacaine can reduce stress response and opioid uses, shorten PACU stay, whereas it does not increase use of ephedrine.
