Objective To investigate the value of transcatheter arterial embolization in the treatment of obstinate nosebleeding. Methods Twenty patients with obstinate nosebleed failed with conventional therapy were performed internal maxillary arterial angiography. Transcatheter arterial embolization were carried out immediately after occurance of nosebleeding. PVA or gelfoam particles were injected into the bleeding arteries under fluoroscopy control. Nasal packing was removed to see whether bleeding was stopped. Results Active bleeding occurred in all 20 patients during angiography but was stopped in all patients after embolization without severe complications. Conclusions Transcatheter arterial embolization is an useful mini-invasive method in the treatment of obstinate nosebleeding.

Objective To investigate the application value of spiral CT imaging in diagnosing costal cartilage diseases. Methods CT volume scan with 1～7mm layer thinkness and 1～2.5mm layer distance was performed in 28 cases of costal cartilage diseases and 200 cases of controls. All of the original images were processed to form the thin layer reconstruction of low contrast and high contrast, and then the reconstructed images were transmitted to CT 3D work-station to perform the image reconstruction by MPR, MIP and SSD methods. The ability of different image techniques in displaying costal cartilage was compared, and costal cartilage pathological changes were analyzed. Results The CT scanning images of 228 cases could display the costal cartilage after the management of MPR, MIP and SSD, and the images managed with MIP and SSD were better. Among 28 patients with costal cartilage diseases, 13 cases of costal cartilage damage,9 cases of costal cartilage inflammation and 6 cases of costal cartilage malformation were found. Conclusion Spiral CT image could display the costal cartilage perfectly, was a new means of researching costal cartilage morphology in living body, and was the best imaging technique of researching costal cartilage disease without trauma.

Objective To explore the relationship between preoperative serum pro-adrenomedullin (pro-ADM) in the patients with closed rupture of small intestine,and postoperative secondary abdominal infection,and to study the value of postoperative serum pro-ADM in assessment of severity of postoperative secondary abdominal infection of this patients.Methods Eighty-five patients with closed rupture of small intestine treated in the emergency surgery from June 2014 to May 2015 were selected.According to the presence of postoperative abdominal infection or not,these patients were divided into infection group and non-infection group.The infection group was further divided into SIRS,sepsis,severe sepsis,septic shock subgroups as per the severity of infection.The levels of serum pro-ADM,interleukin-6 (IL-6),C-reactive protein (CRP) were determined and the acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score was calculated at admission and the first day、the second day and the third day after operation.Comparisons of these biomarkers were carried out to find out the factors associated with postoperative abdominal infection.In addition,ROC curve was used to verify the factors for predicting the abdominal infection of these patients after operation.The relationship between serum levels of pro-ADM and APACHE Ⅱ score after operation was analyzed.The severity of abdominal infection after operation was assessed with laboratory findings.Results Compared with non-infection group,preoperative and postoperative serum pro-ADM (P =0.03,P ＜ 0.01),IL-6 (P =0.02,P ＜0.01) levels and APACHE Ⅱ scores (P ＜ 0.01,P ＜ 0.01) were significantly higher in infection group (P ＜ 0.05).In the infection groups,the postoperative levels of serum pro-ADM and APACHE Ⅱ scores were increased with the severity of infection increased (r =0.924),and the difference between the groups was statistically significant (P ＜ 0.05),but there were no significant differences in IL-6 and CRP levels between two groups.Conclusion (1) The serum levels of pro-ADM before operation has value in predicting the genesis of abdominal infection in these patients after operation.(2) The serum levels of pro-ADM after operation has value in severity assessment of abdominal infection in these patients after operation.

Objective To explore the pattern of lymph node metastasis in patitsen with squamous cell carcinoma of the thoracic esophagus and its significance in lymphadenectomy.Methods The clinical data of 230 patients who received radical esophagectomy with three-field lymphadenectomy was analyzed.The metastatic sites of lymph nodes were correlated with tumor location by chi-square test.Logistic regression was used to analyze the relationship between clinic pathoingical factors and lymph node metastasis.Results Lymph node metastases were found in 133 of the 230 patients(57.8%).The average number of resected lymph nodes was 25.3? 11.4 per patient(range 11～71).The rates of lymph node metastasis were 41.6%,19.44%and 8.3%in the neck,thoracic medi- astinum and abdominal cavity for patients with upper thoracic esophageal carcinoma,33.3%,34.7%and 14%for patients with mid- die thoracic esophageal carcinoma and 36.4 %,34.1%and 43.2 %for patients with lower thoracic esophageal carcinoma.No signifi- cant difference in cervical or thoracic metastatic rate was observed among upper,middle and lower thoracic carcinoma.The difference in lymph node metastatic rate for nodes in the abdominal cavity was significant among upper,middle and lower thoracic carcinoma. The lower thoracic esophageal cancers were more likely to metastasize to the abdominal cavity.Logistic-regression showed depth of tu- mor invasion and angiolymphatic invasion were factors influencing lymph node metastasis.Conclusion Cervical and mediastinal node dissection should be performed independently from tumor location.Abdominal node dissection should be conducted more vigorously for lower thoracic esophageal cancer than of other locations.Patients with greater tumor grade,depth of tumor invasion and angiolymphatic invasion were more prone to develop lymph node metastasis.

Insoluble breviscapin was chosen as the model drug. Bi-layer osmotic pump technology and gel matrix technology were used to prepare the breviscapin sustained and controlled release preparations. Dissimilarity factors (f1) and similarity factors (f2) were applied as similar judgment index to compare the effects of in vitro conditions on the release behavior of different types of breviscapin sustained and controlled release preparations. The tolerance of in vitro release conditions of bi-layer osmotic pump technology and gel matrix technology were studied. The results showed that in vitro release conditions have a greater impact on the gel matrix sustained release formulations, while have almost no effects on the osmotic pump controlled release formulations. Therefore, osmotic pump controlled release technology is less affected by the drug release environment. And it has a very good application prospect.

To study the preventive effect of Grifola frondosa on nonalcoholic steatohepatitis (NASH). The rat model of NASH was established by feeding high-fat diets for 12 weeks and intervened with 0.5 g · kg(-1) · d(-1) and 1.0 g · kg(-1) · d(-1) of C. frondosa powder suspensions. The degrees of hepatocyte fatty degeneration and inflammation were observed under the optical microscope with routine HE staining. The NAFLD activity scores (NAS) were calculated. Serum ALT, AST and hepatic TG and CHOL were tested by the biochemical method. The hepatic MDA was examined by thiobarbituric acid method. The hepatic SOD was tested by the xanthine oxidase test. The hepatic GSH-PX activity was determined by the dithio-nitrobenzoic acid method. Hepatic TNF-α and IL-6 were detected by the enzyme-linked immunosorbent assay (ELISA). The NASH model group induced by high-fat diets showed higher hepatic NAS, ser- um ALT, AST, CHOL and hepatic TG, CHOL, MDA, TNF-α, IL-6 (P < 0.01 or P < 0.05) and lower serum TG and hepatic SOD, GSH-PX (P < 0.01, P < 0.05) than the normal control group. After being intervened with different doses of G. frondosa, the NASH group revealed significantly lower hepatic NAS, serum ALT and hepatic TG, CHOL, MDA, TNF-α and IL-6 (P < 0.05) and higher hepatic SOD, GSH-PX (P < 0.05) than the model group. G. frondosa may prevent the further development of NASH by improving the disorder of lipid metabolism in rats with NASH induced by high-fat diets, relieving the level of oxidative stress and reducing the generation of inflammatory cytokines.
