Objective We sought to determine the incidence,clinical features,and risk factors for retroperitoneal hematoma(RPH)after percutaneous coronary intervention(PCI).Methods A retrospective analysis yielded 21 cases of RPH out of 3,729 consecutive patients undergoing PCI between January 2000 and September 2005 in Anzhen hospital.Cases were compared with a randomly selected sample of 30 control subjects without RPH.Predictors were studied using univariate and multivariate analysis.Results The incidence of RPH was 0.6%.Anemia(100%)was a most universal feature.Features of RPH included hypotension(95%),diaphoresis(57%),groin pain(48%),abdominal pain(38%)and back pain(38%).The following variables were found to be independent predictors of RPH:female gender(odds ratio OR=5.23,P

BACKGROUND:Studies have different views on the effect of repetitive transcranial magnetic stimulation applied in stroke patients for improving motor function.
OBJECTIVE:To evaluate the effect of repetitive transcranial magnetic stimulation on rehabilitation of motor function in patients with stroke.
METHODS:We searched Cochrane Central Register of Control ed Trials, PubMed, ISI Web of science, Medline, EMBASE, China Biology Medicine disc, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodical, Wanfang Data (from database building to July 2013) for randomized control ed trials concerning repetitive transcranial magnetic stimulation on improving motor function in patients with stroke. The included studies were evaluated according to the method recommended by the Cochrane Col aboration. Meta analysis was performed in qualified literatures. The extracted data were analyzed by RevMan 5.1 software and GRADEprofiler 3.6 software.
RESULTS AND CONCLUSION:A total of 23 trials were included (intervention group n=400, control group n=301). Quantitative analysis was conducted in seven studies, and descriptive study was performed in the remaining studies. Meta-analyses analyzed Fugl Meyer Motor Scale and Barthel index. Results showed that Fugl Meyer Motor Scale [SMD=0.48, 95%CI(0.10, 0.86)] and Barthel index [SMD=1.38, 95%CI (0.68, 2.09)] were significantly higher in the intervention group than that in the control group. In accordance with The Grading of Recommendations Assessment, Development and Evaluation, outcome indexes were evaluated, and the two indexes were graded low quality. The current evidence shows that repetitive transcranial magnetic stimulation appears to enhance motor function and activities of daily living of the patients with stroke. Considering the limitations of the included studies, more multi-central randomized control ed trials with large sample sizes and high qualities are required in future to verify the therapeutic efficacy of repetitive transcranial magnetic stimulation on motor function of stroke patients.

OBJECTIVE:To explore the clinical efficacy and safety of cetuximab combined with NP regimen and radiotherapy in the treatment of advanced non-small cell lung cancer(NSCLC). METHODS:76 cases of advanced NSCLC were selected and randomly divided into control group and observation group according to different therapy methods,with 38 cases in each group. Control group received NP regimen(cisplatin 25 mg/m2+navelbine 12.5 mg/m2)+thoracic IMRT;observation group was additional-ly given cetuximab 400 mg/m2(first day),with maintenance dose of 250 mg/m2 weekly and last for 13 weeks. Short-term efficacy, survival situation were compared between 2 groups as well as the levels of T lymphocyte,Th1,Th2,immuneglobulin(Ig) and complement. The occurrence of ADR was recorded. RESULTS:The total effective rate of observation group was 86.84%,which was significantly higher than that of control group(65.79%),with statistical significance(P<0.05). Average survival period and 2-year survival rate of observation group were 18.70 months and 55.26%,which were significantly longer or higher than those of control group (14.75 months,31.58%),with statistical significance (P<0.05). The improvement rate of survival quality was 94.74% in observation group,which was significantly higher than 68.42% in control group,with statistical significance (P<0.05). After treatment,the levels of CD4+,CD4+/CD8+ and IgG were significantly increased in 2 groups,while the levels of CD8+, Th1,Th2 and Th1/Th2 were significantly decreased;the observation group was better than the control group,with statistical signifi-cance(P<0.05);there was no statistical significance in the levels of CD3+,IgA,IgM and complement 4 between 2 groups(P>0.05). There was no statistical significance in the incidence of ADR between 2 groups (P>0.05). CONCLUSIONS:Cetuximab combined with NP regimen and radiotherapy can improve clinical efficacy of advanced NSCLC,improve survival quality,prolong survival time and promote the recovery of Ig,complement and T lymphocyte,with good safety.

Objective To assess the diagnostic value of combining aortic dissection detection risk score (ADDRS)with D-dimer in patients with suspected acute aortic dissection(AAD). Methods We retrospectively identified 525 patients with chest pain and with calculated ADDRS and available D-dimer on admission between January 2015 and December 2016. ADDRS ≤1 was defined as ′low probability′ and that >1 as ′high probability′. Results AAD were diagnosed in 106(20.2%)patients. In patients with ADDRS of 0,1 case of AAD was identi-fied and in those with ADDRS of 1,40 were identified while in 76 patients with ADDRS of 2 and 3,71 cases of AAD were identified. D-dimer with threshold of 0.5 mg/L had a negative predictive value of 100%and a specificity of 76.6% in patients with ADDRS of 0. In patients with ADDRS of 1,D-dimer had a negative predictive value of 98.6%. D-dimer showed a negative predictive value of 99.6% and a positive predictive value of 22.3% in patients with low probability. Conclusions High ADDRS benefits confirming AAD. Low ADDRS combined with negative D-dimer is safe and efficient for ruling out AAD ,while low ADDRS with positive D-dimer needs further aortic imaging.

Objective To evaluate the effect of pretreatment with botulinum toxin A injected intrath?ecally or locally at the incision site on the neurokinin?1 ( NK?1) receptor internalization in the spinal dorsal horn in a rat model of incisional pain. Methods Male Sprague?Dawley rats, weighing 280-300 g, aged 6-8 weeks, were used in the study. The experiment was performed in two parts. ExperimentⅠ Twenty?seven rats with no sign of nerve injury at day 7 after successful catheterization were selected and divided into 3 groups (n=9 each) using a random number table: control group (C1 group), incisional pain group (IP1 group) and intrathecal botulinum toxin A group (BoNT∕A1 group). At 24 h before operation, botulinum tox?in A 0.5 U ( in 10μl of normal saline) was injected intrathecally in group BoNT∕A1, and normal saline 10μl was injected intrathecally in group IP1. ExperimentⅡ Twenty?seven rats were selected and divided into 3 groups (n=9 each) using a random number table: control group (group C2), incisional pain group (IP2 group) and locally injected botulinum toxin A at the incision site group (BoNT∕A2 group). At 24 h before op?eration, botulinum toxin A 2 U ( in 0.4 ml of normal saline) was injected subcutaneously at the incision site and into the plantar surface, and normal saline 0.4 ml was injected subcutaneously at the incision site and into the plantar surface in group IP2. Six rats in each group were selected, and the cumulative pain score (CPS) was recorded, and the mechanical paw withdrawal threshold ( MWT) in the right hindpaw was measured be?fore administration, before operation, and at 3 h and 1, 3, 5 and 7 days after operation. At 3 h after opera?tion, 3 rats in each group were selected and sacrificed, and the lumbar segment ( L4,5 ) of the spinal cord was removed for determination of the expression of NK?1 receptors in the spinal dorsal horn by immunofluores?cence. Results ExperimentⅠ Compared with group C1, the CPS was significantly increased at 3 h and 1, 3, 5 and 7 days after operation, the MWT was significantly decreased at 3 h and 1 and 3 days after opera?tion, and the expression of NK?1 receptors in the spinal dorsal horn was significantly up?regulated in group IP1, and the CPS was significantly increased at 3 h and 1, 3 and 5 days after operation, the MWT was sig?nificantly decreased at 3 h after operation ( P<0.05) , and no significant change was found in the expression of NK?1 receptors in the spinal dorsal horn in group BoNT∕A1 (P>0.05). Compared with group IP1, the CPS was significantly decreased, and the MWT was significantly increased at 3 h and 1, 3, and 5 days after oper?ation, and the expression of NK?1 receptors in the spinal dorsal horn was significantly down?regulated in group BoNT∕A1 (P<0.05). ExperimentⅡ Compared with group C2, the CPS was significantly increased at 3 h and 1, 3, 5 and 7 days after operation, the MWT was significantly decreased at 3 h and 1, 3, 5 and 7 days after operation, and the expression of NK?1 receptors in the spinal dorsal horn was significantly up?regu?lated in group IP2, and the CPS was significantly increased at 3 h and 1, 3, 5 and 7 days after operation, the MWT was significantly decreased at 3 h after operation ( P<0.05) , and no significant change was found in the expression of NK?1 receptors in the spinal dorsal horn in group BoNT∕A2 ( P>0.05) . Compared with group IP2, the CPS was significantly decreased at 3 h and 1, 3, and 5 days after operation, the MWT was signifi?cantly increased at 3 h and 1 and 3 days after operation, and the expression of NK?1 receptors in the spinal dorsal horn was significantly down?regulated in group BoNT∕A2 (P<0.05). Conclusion Pretreatment with botulinum toxin A injected intrathecally or locally at the incision site can inhibit the internalization of NK?1 re?ceptors in the spinal dorsal horn in a rat model of incisional pain.
