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 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 study the relationship between red blood cell distribution width (RDW) and the malignant arrhythmia event of patients with chronic heart failure (CHF) during hospitalization. Methods A retrospective study was conducted. The clinical data of patients with CHF admitted to Department of Emergency and Cardiology of Peking University Third Hospital from January 2014 to February 2016 were reviewed. The patients with New York Heart Association (NYHA) Class Ⅱ, Ⅲ, Ⅳ at hospital admission and courses lasted at least six months were enrolled. The patients were divided into two groups according to malignant arrhythmia events (ventricular tachycardia, ventricular flutter or ventricular fibrillation) during hospitalization, i.e. malignant arrhythmia group and non-malignant arrhythmia group. The value of RDW and left ventricular ejection fraction (LVEF) were compared between two groups, and correlation of RDW, LVEF and malignant arrhythmia events by Spearman rank correlation analysis were studied, and the predictive value of RDW and LVEF for malignant arrhythmia events in patients with CHF was analyzed with receiver operating characteristic (ROC) curve. Results A total of 226 CHF patients were enrolled with 148 male and 78 female, the average age was (61.52±13.27) years old (range: 26-91 years old), the average hospitalization days were (14.5±3.5) days (range: 14-21 days), and malignant arrhythmia occurred in 102 patients (45.13%) during hospitalization. There were no statistically differences in gender, age, past history, etiology of heart disease, the usage of angiotensin receptor converting enzyme inhibitors (ACEI) or angiotensin Ⅱ receptor inhibitors (ARB) and beta blockers, serum potassium levels and so on between two groups. Compared with non-malignant arrhythmia group, the value of the RDW was significantly increased in malignant arrhythmia group [(13.28±1.07)% vs. (12.87±1.32)%, t = 2.531, P = 0.012], but the levels of LVEF was significantly reduced (0.425±0.116 vs. 0.458±0.104, t = 2.249, P = 0.026), the proportion of patients with NYHA Class Ⅱ was significantly lower (4.90% vs. 19.35%, χ2= 10.451, P = 0.000) and that of NYHA Class Ⅳ was just the opposite (57.84% vs. 41.13%, χ2 = 6.264, P = 0.011). The value of the RDW showed positively correlation with the malignant arrhythmia events (r = 0.758, P = 0.023), while LVEF was negatively correlated (r = -0.719, P = 0.019). The area under the ROC curve (AUC) for predicting the malignant arrhythmia events of RDW and LVEF was 0.882 [95% confidence interval (95%CI) = 0.839-0.925), 0.903 (95%CI = 0.866-0.941), respectively. The sensitivity and specificity for RDW in predicting in-hospital malignant arrhythmia event respectively were 82.0% and 79.0% with the optimal cut-off of 14.20%, and those for LVEF were 78.0% and 85.0% with the optimal cut-off of 0.375. Conclusion RDW can be used to predict the occurrence of malignant arrhythmia in patients with CHF during hospitalization.

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.
