Objective To acknowledge the value of interventional therapy in gastrointestinal massive bleeding after abdominal surgery. Methods Retrospectively analyzed 11 patients with acute gastrointestinal bleeding after abdominal surgery, failure to conservative treatment and then undergone emergency angiography or interventional therapy. The correlative evaluation of DSA and interventional therapy was summarized. Results All together 11 case of abdominal postoperative massive gastrointestinal bleeding were undertaken DSA, revealing the bleeding sites as follows: the left gastric artery in 1 case, the gastroduodenal artery pseudoaneurysm in 4, hepatic artery pseudoaneurysm in 2, splenic artery pseudoaneurysm in 1, infected pseudoaneruysm of the branches of the inferior mesenteric artery in 1 and small branches of the superior mesenteric artery in 2 cases. Conclusion Interventional therapy in the treatment of gastrointestinal massive hemorrhage after abdominal surgery is effective.

BACKGROUND:Cytokines secreted from neurons and glial cel s in early stage of spinal cord injury probably are essential factors for inducing secondary immunologic injury.
OBJECTIVE:To investigate the effects of interleukin-1β, interleukin-6 and interleukin-17 on inflammatory reaction after acute spinal cord injury.
METHODS:A total of 75 adult male Sprague-Dawley rats were randomly divided into control group and the spinal cord injury groups:1, 6, 24 and 72 hours. A rat model of incomplete spinal cord injury was established by the modified Al en weight drop method. The control group just underwent laminectomy. Injured spinal cord and spleen tissues were col ected at corresponding time points after model induction. Immunohistochemical staining was used to detect the distribution and expressions of interleukin-6 and interleukin-17 in spinal cord tissue. Western blot assay was utilized to detect the changes in p-STAT3 expression in injured spinal cord. RT-PCR was applied to measure the mRNA expression of interleukin-1β, interleukin-6 and interleukin-17 in the spleen.
RESULTS AND CONCLUSION:The expression levels of p-STAT3, interleukin-1β, interleukin-6, and interleukin-17 were significantly higher in the spinal cord injury groups than those in the control group (P<0.05). The expression of inflammatory cytokines increased immediately after injury. Interleukin-1βand interleukin-6 levels peaked at 6 hours, and then decreased. p-STAT3 and interleukin-17 levels peaked at 24 hours, and then decreased. The expression was stil higher at 72 hours than that in the control group. Results suggested that the expression of p-STAT3-mediated pro-inflammatory cytokines interleukin-1βand interleukin-6 in early stage increased. Inflammatory cascade would enlarge in the injured area, which probably induced secondary spinal cord injury and increased interleukin-17 levels. These possibly played a key role in secondary inflammatory reaction.

Objective:To investigate the effect of recombinant Elafin on A549 apoptosis induced by paraquat and the underlying mechanism.Methods:pEGFP-C1-Elafin was transformed into A549 competent cells by electroporation.Transformed A549 was cultured for additional 24 h before Elafin mRNA was detected by RT-PCR and cocultured with or without various concentration of paraquat( PQ ) for different duration.A549 apoptosis percentage and reactive oxygen species ( ROS ) content were tested by flow cytometry .Nuclear factor erythroid like-2(Nrf2) heme oxygenase-1(HO-1) were examed by Western blot .Results:Elafin expressed successfully in A549 after transformation.PQ caused A549 apoptosis in a concentration dependent manner and leaded to ROS content increasing and Nrf2 and HO-1 decreasing.However,elafin could inhibit ROS production and A549 apoptosis,upregulate Nrf2 and HO-1.Conclusion:Elafin could restrict A549 apoptosis to some extent and the possible mechanism lied in its ability to upregulate Nrf2 ex-pression.

Objective To investigate the current prevalence of depressive disorder and the associated factors in pa?tients with essential hypertensive from cardiovascular divisions of tertiary general hospitals. Methods A Chinese version of Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition) Axis I Disor?ders was conducted by five mental health professionals on 876 essential hypertensive outpatients at cardiovascular divi?sions of tertiary general hospital. Data on the socio-demographic and clinical characteristics of these hypertensive pa?tients were also collected. Results The current prevalence of depressive disorders among essential hypertensive outpa?tients of tertiary hospitals was 16.6%(145/876). Risk factors for depressive disorders in hypertensive patients included fe?male gender (OR=2.817, 95%CI:1.161~6.885), being 65-year-old and older (OR=1.747, 95%CI:1.118~2.688), non-marital status (OR=2.023, 95%CI:1.203~3.398), gradeⅢhypertension (OR=1.776, 95%CI:1.226~2.333) and car?diovascular diseases (OR=2.018, 95%CI:1.427~2.587). Conclusion Essential hypertensive outpatients, who receive med?ical services at cardiovascular divisions of tertiary general hospital, have high prevalence of depressive disorders. Clini?cians should pay more attention to the mental health of outpatients with essential hypertension.

Background Some researching results of sodium hyaluronate eye drops treating dry eye have been reported home and abroad.To evaluate these results using the method of evidence-based medicine (EBM) has an important clinical significance.Objective This secondary study was to systematically evaluate the efficacy of sodium hyaluronate eye drops for the treatment of dry eye.Methods Meta analysis was adopted in this study.The electronic bibliographic databases were searched according to the prescribed strategy,including Medline,PubMed,VIP,CBM,CNKI,Wanfang Data using the method of Cochrane systematic review.The literature published time was limited from the commencement of each database to December,2011.Randomized controlled trials (RCTs) of sodium hyaluronate eye drops treating dry eye were included and the methodological quality of the RCTs was assessed by two evaluators using Jadad measuring scale,and homogeneous evaluation by Meta-analysis was performed.Statistical analysis of clinical data was performed using RevMan 5.0 software provided by the Cochrane Collaboration.With odds ratio (OR) value as the effect index,the randomized effect model was used to analyze the clinical heterogeneity.Results A total of 4 RCTs involving 686 patients were included.Jadad scale evaluation showed 7 points in 2 literature,4 points in 1 literature and 2 points in 1 literature.In all the RCTs,344 patients with dry eye were treated using sodium hyaluronate as the sodium hyaluronate eye drops group,and 342 dry eyes applied placebo,normal saline solution,hydroxymethyl cellulose,hydroxypropyl methyl cellulose respectively as the control group.Meta-analysis indicated that the total effective rate (OR) was 2.55 with the 95％ confidence interval (CI) 0.94-6.93.The symptoms were improved in 183 cases in the experiment group and 130 cases in the control group.No significant difference was found in the OR between the sodium hyaluronate eye drops group and the control group (Z =1.84,P=0.07).Conclusions Meta-analysis indicates that sodium hyaluronate eye drops can improve the symptom of dry eye,but have no significence with the control group.However,owing to fewer number and uneven quality of included RCTs,the large sample size and multicenter of RCTs is still needed to verify the superiority of sodium hyaluronate eye drops for dry eye.
