Objective To explore the safety and success rate of endovascular intervention in the treatment of Budd-Chiari syndrome. Methods Double balloon-catheters were inserted into proximal and distal of the obstructive segments in inferior vena cava of 18 cases of Budd-Chiari syndrome respectively. The balloon was filled with contrast medium. Perforation in the obstructive segments was done by hard core through a balloon-catheter, using another one as a guide. Results The length of obstructive segments in inferior vena cava ranged from 1.2cm to 8.0cm. In the 18 cases of Budd-Chiari syndrome, 15 obstructive segments were perforated successfully(83.3%), of whom 6 cases were performed by single balloon-catheters with acute pericardial wadding in 1 case and 9 cases by double balloon-catheters without vessels damage and bleeding. Conclusions The membrane perforation induced by double balloon-catheters is a key process of endovascular interventive technique in the treatment of Budd-Chiari syndrome.

BACKGROUND: Apart from anticoagulation property and suppressing platelet congregation capability, tongxinluo preparation has been proved by traditional Chinese medicine to possess certain function for protecting endothelial cells.OBJECTIVE: To observe the influence of Chinese medicinal herb "tongxinluo" compound on adhesion molecule expression in brain ischemia-reperfusion (IR) animal model.DESIGN: Randomized and controlled experiment.SETTING: Department of Neurology, Changzheng Hospital Affiliated to the Second Military Medical University of Chinese PLA.MATERIALS: This experiment was conducted at the laboratory of the Department of Neurology, Shanghai Changzheng Hospital, between October 2002 and January 2003. Totally 25 male SD rats were randomized into sham-operation group of 5 rats, model group of 10 rats and tongxinluo group of 10 rats.METHODS: Middle cerebral artery was occluded using thread-bolt method to induce focal brain IR model in rats. In sham-operation group,nylon thread was placed around the external carotid artery approximating to the branch of internal carotid artery, and the other procedure was the same as that in model group. Rats in tongxinluo group were given tongxininfusion before IR for 1 consecutive week, which was replaced by physiological saline of the same dosage in model group and sham-operation group. Brain tissues were obtained under anesthesia condition and cut into slices; conventional HE staining, immunohistochemical and in situ hybridization staining were conducted.MAIN OUTCOME MEASURES:① The number of intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1)positive microvessels following IR injury.② The number of ICAM-1 and VCAM-1 mRNA positive microvessels following IR injury.RESULTS:① In sham-operation group,ICAM-1,VCAM-1 protein andICAM-1 mRNA positive microvessels could not be observed in hemispheric cortex and basal ganglion at the operative side.② In model group,the positive expression of ICAM-1, VCAM-1 protein and ICAM-1 mRNA obviously increased at the ischemic side at 6-hour reperfusion following 2-hour ischemia.③ In tongxinluo medication group,the positive protein and mRNA-expressing microvessls were found remarkably reduced in number in ischemic side hemispheric cortex and basal ganglion [(10.42 ±1.98),(12.42±2.14)/HP; (8.54±2.00), (11.12±1.56)/HP] (P ＜ 0.05), but the positive VCAM-1 protein-expressing microvessels did not change remarkably (P ＞ 0.05).CONCLUSION: Tongxinluo can suppress ICAM-1 transcription and translation following rat brain IR, thus attenuating inflammatory injury induced by brain ischemia.

Objective To evaluate the feasibility and efficacy of chemoradiotherapy for locally advanced (inoperable) rectal cancer. Methods Seventy-six patients with locally advanced (T_4) or recurrent rectal cancer were randomized into two groups of concurrent chemoradiotherapy with either oxaliplatin plus 5-FU (oxaliplatin 130 mg/m~2, day 1,5-FU 350 mg/m~2, day 1 -5 ,LV 200 mg/m~2, day 1 -5, 4 weeks per cycle) or capecitabine (1650 mg/m~2, day 1 -14, 3 weeks per cycle) alone. All patients received pelvic three-dimensional conforrnal radiotherapy (3 DCRT) of 46 -50 Gy in 23 -25 fractions, with a boost of 14 -18 Gy in 7 -9 fractions. Results The median follow-up time was 19 months. The overall response rate was 64% in the oxaliplatin/5-FU group comparing with 58% in the capecitabine group (χ~2 = 0. 08 ,P =0. 772), with the median survival time of 22 months and 18 months (u = 17.71, P = 0. 077), respectively. The overall survival in the two groups was 68% and 63% at 1 year, and 21% and 19% at 2 years, respectively (χ~2 = 0. 97, P = 0. 326). There were no treatment-related deaths or grade 4 toxicities. Neutrocytopenia (39. 5% vs 77.7%, z = -3.97,P =0. 0001), diarrhea (47.4% vs 88.9%, z = -4. 78, P = 0. 0001), nausea and vomiting (68.4% vs 97.2%, z = -3. 17, P = 0. 0001), and neurotoxicity (5.3% vs 66.7%, z= -6.56, P= 0.0001) were more common in the oxaliplatin/5-FU group. Conclusions Concurrent chemoradiotherapy is well-tolerated and effective in patients with locally advanced (inoperable) rectal cancer.

Objective:To explore the relationship between the expressions of MCM5 and E2F-1 with the genesis,clinicopathological parameters of gastric carcinoma.Methods:Immunohistochemistry SP method was used to detect the expressions of MCM5 and E2F-1 in gastric car- cinoma tissues of 57 cases and in normal gastric mucosa of 20 cases.The correlation between expressions of MCM5 and E2F-1 and clinicopathological parameters of gastric carcinoma was analysed. Results:The positive expression rate of MCM5 in cancer tissues was 71.9%(41/57),while in normal mucosa it was 0(0/20).The difference between the two groups was statistically significant (P0.05).The correlation between MCM5 and E2F-1 expressions in gastric carcinoma was highly significant positive(r=0.635,P=0.000).Conclusion: Overexpression of MCM5 and E2F-1 corelates with occurence and development of gastric carcinoma.MCM5 and E2F-1 may work in the early phase in carcinogenesis of gastric carcinoma.

AIM To study the anti-inflammatory effects and mechanisms of pristimerin. METHODS Several inflammatory models were established, such as ear edema induced by croton oil, hind paw swelling by carrageenan, elevation of capillary permeability by acetic acid in mice and a-cute peritonitis induced by carrageenan in rats. Protein content was measured by Coomassie brilliant blue method, nitric oxide (NO) content by Griess reaction assay, N-acetyl-?-D-glucosamini-dase (NAG) activity by colorimetry, superoxide dismutase (SOD) activity by hydroxylamine method, catalase (CAT) activity by ultraviolet spectro-photometry, and malondialdehyde (MDA) content by fluorescence method in peritoneal exudate in rats. RESULTS Pristimerin ip 0. 156 - 0. 625 mg ? kg-1 or im 1-4 mg - kg-1 inhibited ear edema, hind paw swelling, and elevation of capillary permeability in mice. In the rat peritonitis induced by carrageenan, pristimerin im 1 - 2 mg ?kg-1 reduced neutrophil counts, lessened protein and NO content, inhibited the production of MDA and decreased NAG activity, while augmented the SOD and CAT activity in exudate. CONCLUSION Pristimerin has a significant anti-inflammatory effect which may be related to the inhibition of NO production, scavenging oxygen free radicals, anti-lipoperoxidation and stabilizing lysosome membrane.

Objective To compare the therapeutic effects and side effects of cisplatin-S-1 (CS) program and docetaxel-cisplatin-S-1(DCS) program on patients with malignant gastric tumor who were treated by laparoscopic gastrectomy.MethodsA total of 67 patients in our hospital from January 2010 to June 2013 were included in this study,of which 33 cases accepted cisplatin-S-1 program (CS group),34 cases accepted DCS program (DCS group).The related side effects including diarrhea,nausea and acute upper respiratory infection,change of routine blood tests,blood biochemical index,and death caused by chemotherapy were analyzed.The related index of surgery including operation time,blood loss,recovery time of gastrointestinal function,pain incidence,hospital stay,lymph nodes resection success rate,postoperative infection,obstruction,intestinal emptying delays were recorded.Meanwhile,the 3-year survival rate after operation and postoperative 3-year recurrence rate between the two groups were compared.Results There was no significant difference in operation time,intraoperative blood loss,postoperative recovery time of gastrointestinal function,the lymph nodes resection success rate,the incidence of postoperative pain,as well as the length of hospital stay,postoperative infection rate,and complications such as obstruction and intestinal emptying delays between the two groups(P>0.05).And there was no significant difference in chemotherapy-related complications between the two groups(P>0.05).But the postoperative 3-year survival rate and postoperative 3-year recurrence rate of DCS group was better than those of the CS Group(P<0.05).Conclusion There is no significant difference in complications and surgery-related index between the two preoperative chemotherapy.However,the DCS programs have more advantages in therapeutic effects.

Objective To explore the relationship between HLA sensitization and crossmatch and to assess its clinical value. Methods The subjects were divided into 3 groups :high sensitization group (PRA≥40％),low sensitization group (40％＞PRA≥10％) and non-sensitization group (PRA＜10％) according to the HLA antibody level detected by ELISA. The results of crossmatch were compared among the 3 groups. Results There was significant difference among the ratio of positive crossmatch in high sensitization group (39.4％),low sensitization group (10.5％)and non-sensitization group (2. 6％). Conclusion The sensitization level is positively correlated with the result of crossmatch. The improvement of matching precision can be made by using both of techniques mentioned above.

BACKGROUND:Currently, there are few reports on the effects of Caspase inhibitors combined with Cocktail protease inhibitors on isolation and purification of islet cel s. OBJECTIVE:To explore the effects of Caspase inhibitors and Cocktail protease as protectors on islet cel s during isolation and purification process. METHODS:New-born pigs were selected to separate, purify and culture the islet cel s, and after 24 hours of culture, the specimens were divided into three groups:blank control group, experimental group A (Caspase inhibitors and Cocktail protease were added only during digestion process), and experimental group B (Caspase inhibitors and Cocktail protease were added both during digestion and culture processes). AO-EB staining was used to qualitatively observe cel morphology and apoptosis. Flow cytometry was employed to quantitatively detect cel viability and apoptosis. RESULTS AND CONCLUSION:Percentages ofβcel s were 66.91%in blank control group, 84.58%in the experimental group A, and 87.15%in the experimental group B. The proportions of living cel s, apoptotic cel s and dead cel s were 56.52%, 16.15%, 21.25%in the blank control group, 62.27%, 14.66%, 14.47%in the experimental group A, and 73.09%, 6.83%, 10.28%in the experimental group B, respectively. These findings indicate that in the process of digestion and culture in vitro, Caspase inhibitors and Cocktail protease inhibitors can both obviously decrease the loss of cel s, and increase the percentage of islet beta cel s.
