Objective To evaluate the usefulness of bilateral internal iliac arterial embolization in the treatment of hemorrhagic cystitis after bone marrow transplantation. Methods Among 28 patients with hemorrhagic cystitis, 7 patients experienced bilateral internal iliac artery embolization because of serious hemorrhage that couldn′t be controlled by conservative treatments,including CML (n = 3) , AML(n = 2) , ALL (n = 1),acute myelomonocytic leukemia(M4, n = 1). Embolization of the target vessels was performed by using gelfoam particleas for bilateral internal iliac arterial visceral branches. Results Gross hematuria disappeared in 4 cases after embolization by gelfoam particles. The time of bleeding controlled continued 2-10 d(mean 6 d). No rebleeding was observed in all of the cases during the 12 - 82 days follow up.Gross hematuria markedly reduced in another 3 cases after embolization. But failure occurred in other two patients. No definite complication related to the procedure was noted. Conclusion Bilateral internal iliac arterial embolization is an effective, less invasive, and safe method for serious hemorrhagic cystitis after bone marrow transplantation.

Objective To summarize the nursing points for patients with mid-stage hepatocellular carcinoma who are receiving radiofrequency ablation (RFA) combined with 131I-chTNT treatment. Methods The clinical data of 12 patients with mid-stage hepatocellular carcinoma, who were encountered at authors’ hospital during the period from Aug. 2009 to Sep. 2011, were retrospectively analyzed. RFA combined with 131I-chTNT was carried out in all patients. Preoperative prophylactic anti-allergy medication and protection measure for the thyroid were employed. After the operation strengthened radiation protection and close observation for complications were conducted. The results were analyzed. Results After active treatment and proper nursing, the tumor shrank in all patients. All the patients were followed up for 5 - 48 months with a median follow- up time of 31 months. The median overall survival time was 43 months. No serious complications such as bone marrow suppression or thyroid dysfunction occurred. Conclusion For the treatment of mid-stage hepatocellular carcinoma, 131I-chTNT combined with RFA has satisfactory therapeutic effect. Close observation for the occurrence of complications and careful nursing can improve the quality of life and prolong the survival time.

Objective To determine the effective prognostic parameter and the best prognostic index of gastiric carcinoma.Methods The prognostic relevance of clinical and pathological variables were evaluated in 83 patients with histologically proved stomach carcinoma (including the expression of nm23, c erbB2, microbloodvessel and PTNM) by the multivariate analysis of COX regression.Result PTNM staging was the only parameter to enter the COX model.Conclusion The PTNM staging is the most important, reliable and best varible factor in predicting the clinical outcome of stomach cancer.

Objective To evaluate argon-helium cryoablation combined with transcatheter arterial chemoembolization (TACE) in treating advanced hepatocellular carcinoma (HCC). Methods The clinical data of 66 patients with pathologically-proved HCC were retrospectively analyzed. Based on the therapeutic scheme the patients were divided into TACE group (n=31) and combination group (TACE+argon-helium cryoablation, n=35). All the patients were followed up for 5-35 months. The complete remission rate, total effective rate and survival time were evaluated. The short-term and the long-term effectiveness were compared between the two groups. Results Both the complete remission rate and total effective rate of the combination group were significantly higher than those of TACE group (P<0.05). The median survival time of the combination group was significantly longer than that of TACE group (P=0.038). The half-year, one-year and 2-year overall survival rates of the combination group were higher than those of TACE group, although the differences were not statistically significant (P>0.05). Conclusion For the treatment of advanced hepatocellular carcinoma, argon-helium cryoablation combined with TACE can improve the short-term effect and prolong the progression-free survival time, although its exact effectiveness still needs to be confirmed by large sample, multi-central and randomized controlled studies.

A near infrared spectroscopy ( NIRS) method was used for rapid quality evaluation of ferulic acid content in chrysanthemum morifolium cv. ( Chuju) continuous cropping soil. Standard leverage, studentized residual and Mahalanobis distance were calculated to eliminate abnormal samples. After the initial near infrared spectrum was treated by two second derivative and Norris smoothing filter noise, 6000-4000 cm-1 wave number range and 7 factors were chosen for partial least squares ( PLS) calibration model. The results showed that good correlation was presented between the calibration set/validation set and the values determined by high performance liquid chromatography, and the calibration correlation coefficient ( Rc ) and validation correlation coefficient ( Rcv ) were 0. 9914 and 0. 9935, respectively. Root mean square error of calibration (RMSEC), root mean square error of validation (RMSEP) and root mean square error of cross-validation (RMSECV) were 0. 484, 0. 539 and 0. 615, respectively. This method was accurate, reliable, simple, rapid and nondestructive, and could be applied to the fast analysis for ferulic acid in continuous cropping soil.

Objective To probe multislice spiral computed tomography(MSCT) features of superacute cerebral infarction.Methods 19 cases with superacute cerebral infarction were retrospectively analysed.MSCT scans were performed in all patients at 1～6 h after onset,and the lesions were proved by MSCT or MR at 3 h～5 d after onset.MSCT signs of superacute cerebral infarction were observed.Results 17 cases and 2 cases were diagnosed and suspectively diagnosed with superacute cerebral infarction by CT at first visit of patients.CT features of superacute cerebral infarction included hypodense of cerebral parenchyma in 19 cases,local cerebral swelling in 13 cases and hyperdense sign of cerebral artery in 3 cases.Conclusion MSCT plain scan has significant value in diagnosis of superacute cerebral infarction.

Objective To investigate the method of endovascular puncture to establish rabbit models of cerebral vasospasm. Methods New Zealand white rabbits were divided into 5 groups (12 h,1 d,2 d,3 d and 7 d) randomly, and each group was separated into subarachinoid hemorrhage (SAH) subgroup (n = 5) and control subgroup (n = 2). cerebral vascular spasm (CVS) models were established atfer SAH with endovascular puncture. CT scans before and after operation were performed. The internal diameters and the wall thicknesses of posterior communicans artery (PcoA) and basilar artery (BA) were measured with HE stain after the animals were executed. Results CVS model was successfully eastblished in 35 rabbits (SAH subgroup 25,control subgroup 10), resulting a successful rate of 48.61% . Compared with control subgroup, PcoA and BA showed shrinkage of internal diameters of 43.60% and 51.82% 12 h after SAH, respectively, and the shrinkage appeared as biphasic patterns until the 7th study day with another peaks of 29.32% and 45.19%, respectively. Conclusions Endovascular puncture is an effective method to establish rabbit of CVS. The death rate of animals can be decreased with the asage of new interventional material and perfection for the details of operation.

Objective To assess the clinical value of transcatheter arterial chemoembolization (TACE) together with radiofrequency ablation (RFA) and sorafenib in treating recurrent hepatocellular carcinoma (HCC) after surgery.Methods A total of 40 patients with recurrent HCC after surgery, who were encountered at authors' hospital during the period from December 2009 to May 2014, were collected. The patients were divided into the study group (n=20) receiving TACE combined with RFA and sorafenib and the control group (n=20) receiving TACE plus RFA. Within 7-10 days after TACE, RFA was carried out. In the study group, oral sorafenib therapy (400 mg, two times everyday) started at 4 days after TACE. Withdrawal of sorafenib would be ordered if drug resistance occurred. Each patient underwent TACE combined with RFA not less than two times. Results The median survival time of the study group and the control group was 31.0 months and 24.8 months respectively, and statistically significant difference existed between the two groups (P<0.05). The one-year, 2-year and 3-year survival rates of the study group were 85%, 70% and 50%respectively, while the one-year, 2-year and 3-year survival rates of the control group were 80%, 55% and 30% respectively; the differences between the two groups were not statistically significant (P>0.05). The progression free survival (PFS) time of the study group and the control group was 6.8 months and 5.7 months respectively, the difference between the two groups was statistically significant (P<0.05). Conclusion TACE combined with RFA and sorafenib can prolong the overall survival time and the progression free survival time of patients with recurrent HCC after surgery.

Neurofibroma is an autosomal dominant genetic disease which is originated from the abnormal differentiation of neural crest cells and would cause system damage.NF can occur at most organs in the body,while it is rarely seen in the common bile duct.In February 2007,1 old patients with NF was admitted to the Lishui Central Hospital of Zhejiang Province.The results of preoperative magnetic resonance cholangiopancreatography (MRCP) revealed that the common bile duct was slightly dilated,and the diameter of the common bile duct was 1.2 cm.A nodular short T2 signal lesion was detected at the middle part of the common bile duct with the size of 1.4 cm × 1.6 cm.The results of intraoperative rapid frozen section pathological examination showed that the lesion was cholangiocarcinoma,then cholangiocarcinoma resection + biliojejunal Roux-en-Y anastomosis was applied to the patient.Postoperative pathological examination confirmed that the lesion was neurofibroma.The patient was followed up for 7 years and died of pulmonary infection in June 2014.The clinical presentation of neurofibroma of the common bile duct is untypical.Space-occupying lesions detected in the patients with history of bile duct injury or operation should be considered to be diagnosed as neurofibroma.Special attention should be paid to the accuracy of the results of rapid frozen section pathological examination in order to avoid missdiagnosis.

Objective To evaluate the feasibility, safety, and efficacy of Y-shaped jogged stent in patients with malignant hilar biliary obstruction. Methods During the period of January 2010 to June 2015,We retrospectively reviewed 98 cases of malignant hilar biliary obstruction who were received implantation of biliary tract stent. 17 consecutive patients who were treated with Y-shaped jogged stent were identified (group A) during January 2012 to June 2015. Group A was carefully matched according to patients' age, sex, type of tumor, stage, type of biliary obstruction, level of bilirubin at diagnosis, presence of metastasis and treatment, and 17 patients who were underwent unilateral stent placement alone with PTCD were chosen as control group (group B). Patients' baseline characteristics, stenting strategy, complications, stent patency time and survival rates were analyzed, and continuous variables of the two groups were compared using Student's t-test. Categorical variables were analyzed using the Fisher exact test. Results Y-shaped jogged stent implantation group and control groups were closely matched in terms of patients' age, sex, type of tumor, stage, type of biliary obstruction, level of bilirubin at diagnosis, presence of metastasis and treatment ( P>0.05). The bilirubin decreased rate in the two groups was 88.2%and 53.0%respectively (P<0.05). The median time of stent patency after stent implantation was(7.3 ± 1.0)months and(5.7 ± 0.9) months respectively (χ2=4.04,P=0.044), and the median survival time was(9.1 ± 1.5)months and(7.2 ± 1.1)months (χ2=4.60,P=0.032), with significant difference according to Kaplan-Meier analysis. There were no severe complications such as massive hemorrhage, perforation, biliary fistula and severe pancreatitis, which were associated with stent implantation. Conclusions The application of Y-shaped jogged stent is safe, feasible and effective in patients with malignant hilar biliary obstruction. It can relieve the clinical symptoms of biliary obstruction effectively with prolongation of stent patency time and survival rate significantly.
