BACKGROUND AND PURPOSE:We have developed a new thermosensitive liquid embolic agent, PIB nanogel, that can be solidified at body temperature. We thus further investigated the distribution, durability of vascular occlusion, and inflammatory reactions of PIB in embolization of the renal artery of rabbits.

To evaluate the different arteriographic manifestations of acute arterial massive hemorrhage of the gastrointestinal (GI) tract and the efficacy of emergency transcatheter arterial embolization (ETAE).A total of 88 patients with acute massive GI bleeding who experienced failure of initial endoscopy and/or conservative treatment were referred to our interventional department for acute GI arteriography from January 2007 to June 2015. After locating the source of bleeding, appropriate embolic agents, such as spring coil, hydroxyl methyl acrylic acid gelatin microspheres, polyvinyl alcohol (PVA) particles, etc., were used to embolize the targeted vessels. The angiographic manifestations and the effects of embolization of acute arterial massive hemorrhage of the GI tract were retrospectively analyzed.Of the 88 patients, 54 were diagnosed with arterial hemorrhage of the upper GI tract and 34 with arterial hemorrhage of the lower GI tract. Eighty cases were associated with positive angiography, which showed the following: contrast extravasation (only); gastroduodenal artery stenosis; pseudoaneurysm (only); pseudoaneurysm rupture with contrast extravasation; pseudoaneurysms merged with intestinal artery stenosis; GI angiodysplasia; and tumor vascular bleeding. Eight cases were diagnosed with negative angiography. Seven-two patients underwent successful hemostasis, and a total of 81 arteries were embolized. The technical and clinical success rates (no rebleeding within 30 days) in performing transcatheter embolization on patients with active bleeding were 100% and 84.71%, respectively (72 of 85). Within 30 days, the postoperative rebleeding rate was 15.29% (13/85). Of these rebleeding cases, 2 patients were formerly treated with "blind embolization," 7 underwent interventional embolic retreatment, and 3 had surgical operations. All cases were followed-up for 1 month, and 3 patients died from multiple organ failure. No serious complications such as bowel ischemia necrosis were observed.ETAE is a safe, effective, and minimally invasive treatment; because of the diversified arteriographic manifestations of acute GI hemorrhage, the proper selection of embolic agents and the choice of reasonable embolization method are essential for successful hemostasis.

ABSTRACT PURPOSE:Hypertensive cerebral hemorrhage in the basal ganglia is a potentially life-threatening cerebrovascular disease with high mortality. Surgical evacuation is an important treatment for intracerebral hemorrhage. However, little is reported about the comparison on the efficacy of various approaches on the prognosis. METHODS:Clinical data of 80 cases of intracerebral hemorrhage which surgically treated via transsylvian-transinsular approach or transcortical-transtemporal approach were collected. The proportion of post-surgery tracheostomy, incidence of digestive tract hemorrhage, revision surgery, the average length of hospital stay, and the six-month efficacy (defined by an ADL score) rate between these two groups were compared. RESULTS:The six-month efficacy rates were 75% and 50% in patients receiving transsylvian-transinsular and transcorticaltranstemporal surgery, respectively (p<0.05). Compared to the transcortical-transtemporal group, the proportion of revision surgery was statistically significantly lower in the transsylvian-transinsular group, (p<0.05). The proportion of post-surgery tracheostomy, the incidence of digestive tract hemorrhage, and the average length of hospital stay were lower in the transsylvian-transinsular group, compared to the transcortical-transtemporal group, but no statistically significant differences were noted in them between the two groups. CONCLUSION:The transsylvian-transinsular approach for evacuation of intracerebral hematoma demonstrates limited complications, shorter length of hospital stay, and improved long-term efficacy and prognosis. These findings suggest this operative approach has potential for wider application.Key words: Intracranial Hemorrhages. Transsylvian-Transinsular Approach.

Lung transplantation (LTx) historically was performed with cardiopulmonary bypass (CPB) or Off-pump. Recent data suggest an increased interest in extracorporeal membrane oxygenation (ECMO) as perioperative circulatory support by many lung transplantation centers worldwide. However, there are no established guidelines for anesthetic management for LTx. We present a patient with a history of systemic sclerosis and interstitial lung disease complicated by acute onset of systemic pulmonary hypertension and right heart failure undergoing LTx. We aim to discuss perioperative circulatory support, including ECMO bridge to LTx, and how best to consider the varied intraoperative strategies of CPB vs ECMO vs off-pump during LTx, intraoperative maintenance, and coagulation management.

Background: Breast cancer is the most common cancer among women in China. Hence, how best to live with and improve the health-related quality of life (HRQoL) of this growing population of women is thus becoming of great public health importance. The aim of the study was to evaluate the relationship of lifestyle habits to HRQoL among younger and older women who were initially diagnosed with breast cancer within the first two weeks, determine the contribution of lifestyle habits factors on HRQoL.Methods: A multi-center, hospital-based, case control study was conducted among breast cancer women from 22 hospitals in 11 provinces or municipalities in northern and eastern China from April 2012 to April 2013. The Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) simplified Chinese version 4 was used to measure HRQoL. Chi-square test, ANOVA and Multivariable generalized linear models were conducted to verify differences in HRQoL between two groups and to evaluate the contribution of lifestyle habits factors ( including smoking, passive smoking, alcohol intake, Tea, Coffee, Sleep satisfaction, Current life satisfaction, Physical activity, BMI) on HRQoL of breast cancer patients.Results: 1199 eligible breast cancer patients were used for analysis. Younger women (age < 50 years) appeared to show lower scores than older women (age ≥ 50 years) in HRQoL subscales including emotional well being (p = 0.003), functional well being (p = 0.006), breast cancer subscale (p = 0.038), and FACT-B Total scores (p = 0.028). Tea and alcohol consumption, very satisfied with sleep and current life were the strongest predictors of higher HRQoL in younger group. Meanwhile, no coffee consumption, frequent participation in physical activities, high sleep satisfaction and current life satisfaction were the key predictors of higher HRQoL in older breast cancer women.Conclusion: The relationship of the nine lifestyle habit items to HRQoL were different between younger and older women. Associated variable of low HRQoL can help clinicians take intervention early in order to improve the prognosis of breast cancer patients.

Objective: Benign breast disease (BBD), especially benign proliferative breast disease (BPBD), is related to increased breast cancer risk. However, few studies have examined whether conventional breast cancer risk factors influence risk of breast cancer among women with BBD. The aim of this study was to evaluate the associations of lifestyle factors with risk of breast cancer among women biopsied for BBD within a multi-center, hospital-based, case-control study in China, in order to provide scientific basis of health guidance for BBD patients and lay the foundation for primary prevention of breast cancer. Methods: A multi-center, hospital-based, case-control study was conducted. Patients with BPBD (n=608) and patients with non-proliferative breast disease (NPBD) (n=366) were collected from 23 hospitals in 11 provinces during April 2012 to April 2013. A face-to-face survey, baseline data and fasting blood was collected with all study subjects. Serum adiponectin levels were assayed using ELISA. After 10 years, the cumulative incidence rate of breast cancer in the two groups was counted through follow-up. Logistic regression analysis was used to obtain the association between specific factors and risk of breast cancer. Results: After 10 years’ follow-up, 388 BPBD and 240 NPBD cases were included in the final analysis (Table 1), of which 16 (4.12%) and 3 (1.25%) developed breast cancer, respectively. The cumulative incidence of breast cancer between the two groups was significant difference (P=0.041). Compared with women in the NPBD group, BPBD group were more likely to be central obesity (with higher waist-to-hip ratio (WHR)) (OR 24.98, 95% CI 1.845-336.203, P=0.015) and less likely to have physical activity (OR 0.626, 95% CI 0.416-0.943, P=0.025) and less often to eat carrots (OR 0.616, 95% CI 0.398-0.953, P=0.030) (Table 2). Subgroup analyze indicated that, physical activity, eat carrots and ham sausage, body weight, BMI, waist circumference and WHR were statistical differences in premenopausal BPBD patients, while only physical activity (OR 0.423, 95% CI 0.269-0.665 P &lt; 0.001) was the independent risk factors. Meanwhile, among the factors of Tea consumption, Glycemia, Body weight, BMI, Waist circumference, WHR and HMW/total adiponectin ratio in postmenopausal group, only HMW/total adiponectin ratio (OR 0.041, 95% CI 0.002-0.820 P=0.037) was statistically significant factor. These stratified multivariate logistic regression analysis results are shown in Table 3. Conclusion: In patients with BBD, physical activity may be the protect factor for breast cancer carcinogenesis in premenopausal women while lower HMW/total adiponectin ratio is a risk factor for postmenopausal women, which can provide direction for primary prevention of breast cancer.

Males/60 Females). Mean age was 66 + 9 years old (range:30-85). The majority of patients had adenocarcinoma (n¼101;72%), followed by epidermoid (n¼29;21%) and carcinoid tumors (n¼10;7%). Lobectomy was the most common operation (n¼119;85%), followed by anatomic segmentectomies (n¼21;15%). Mean overall operative time was 209 + 80 minutes (214 + 80 for lobectomies and 167 + 51 for segmentectomies; p¼0.01). Mean number of lymph nodes resected was 12 + 6, and the mean number of lymph nodes stations sampled was 6 + 1. There was no conversion to either VATS or thoracotomy in our series; neither major intraoperative bleeding. Postoperative complications occurred in 30 patients (21%). Prolonged air leak was the most common (n¼13;9%) and 7 patients were discharged with a chest tube. Chylothorax occurred in 4 patients (2.8%), but all were treated with dietetic measures. Median length-of-stay was 3 days (IQR:2-6). The overall 30-day mortality was 0.5% (n¼1). One patient had a procedurerelated death, 25 days after a lobectomy. He developed pneumonia, sepsis and multiple organ failure. 138 patients (98.5%) are still under follow-up. Disease recurrence occurred in 7.8% of patients (n¼11). Conclusion: Robot-assisted pulmonary resection is safe, effective and provides good outcomes, even within the context of an initial experience. Further follow-up should provide insight regarding long-term oncologic disease control.
