Objective To evaluate a combination therapy for huge tumors in the buttocks.Methods A total of 11 patients from our hospital were collected,among them 5 cases were of hemangioma,4 cases of neurofibroma,2 cases of soft tissue sarcoma.Before definite surgical resection all cases received tumor embolization with silk thread and gelatin-sponge article using Seldinger's technic.Subsequently,all patients underwent a successful tumor resection. Results Superselective embolization for all the cases'feeding arteries resulted in recession of the tumors and relatively well-demarcated margins,and all the lumps became softer.and the local pain was alleviated.Surgical resection could be radical with avoidance of fatal intraoperative hemorrhage.The 5 cases of hemangioma had a average operative bleeding of 450 ml,4 cases of neurofibroma had 420 ml,2 cases of soft tissue sarcoma had 150 ml.No patients needed intraoperative and postoperative blood transfusion.The operation time was about 2-3 hours,the normal tissues were preserved and the contour and function of the diseased limbs were very good.One case had a delayed incision healing,and the others had a healing by the first intention.There was no recurrence and other complications (like deep venous thrombosis)during a follow-up period of 4-8 months. Conclusions Surgical resection combined with interventional embolism for the treatment of huge tumors in the buttocks can reduce the risk of bleeding effectively during operation.It can improve the success rate of operation leading to satisfactory results.

AIM: To investigate the effect of premedication with clonid in e on the concentrations of catecholamine (CA), angiotention Ⅱ (AⅡ), cortisol a nd carbohydrate metabolism during tracheal extubation. METHODS: Twenty-two patients scheduled for general anesthesia with tracheal intubation were randomly divided into two groups: clonidine group and control group. Oral p remedication with clonidine 5 ?g?kg -1 was taken in clonidine group 6 0 min before anesthesia induction in addition to some common premedication in bo th groups. The change of hemodynamics,arterial plasma concentrations of CA, A Ⅱ, cortisol, blood sugar and lactic acid were measured before anesthesia, befor e intubation and 1,2,5, 10 min after tracheal extubation, respectively. RESULTS: The levels of CA, AⅡ, cotisol, blood sugar and lactic acid were significantly increased during tracheal extubation in both groups,but the levels in control group were higher than those in clonidine group. The change of hemodynamics was more stable in clonidine group than that in control group. CONCLUSION: Oral premedication with clonidine can alleviate stress response during tracheal extubation.

Objective: To discuss the prevalence and influential factors of stroke among population in Jiangxi Province. Methods: Four cities in urban areas and four counties in rural areas were selected firstly, in which two districts or townships were selected; and then three communities or villages were chosen from each district and township, respectively, using the simple random sampling (SRS) method. Finally 15 269 subjects aging 15 years old or above, living in Jiangxi Province ≥6 months were randomly selected to participate in this survey from November 2013 to August 2014. Information of population characteristics, life behavior way, individual disease history were collected through questionnaire survey, and height, weight, waist circumference, blood pressure, body fat rate, visceral fat index and so on were measured by instruments. Risk factors of stroke prevalence were analyzed by the unconditioned logistic regression analysis. Results: A total of 15 269 participants (6 267 males) from 15 364 eligible participants were included in the statistical analysis. Out of which, 7 793 participants came from urban areas, and their average age was (53.04±17.91) years old. In this study, 226 stroke patients (117 males) were found among15 269 participants, including 122 urban participants and 104 rural participants, whose average age was (67.76±9.74) years old. The prevalence of stroke was 1 480.12/100 000 in 2014, which was separately 1 866.92/100 000 and 1 210.84/100 000 among males and females. The prevalence of people aging (45-49) years old was 413.79/100 000 (6/1 450) , while which among people aging 75 years old and above was 3 311.62/100 000 (61/1 842) . The prevalence of stroke among residents in Jiangxi presented an uprising tendency with age increasing (linear-by-linear association χ²=62.23, P<0.01). The research showed that when other influencing factors including gender, BMI, waist circumference, pulse-pressure difference, VAI, and sleeping time in non-working days were controlled, hypertensive patients had a higher risk of stroke than people without hypertension (OR=6.88, 95%CI: 4.90-9.67), drinkers had a higher risk of stroke than non-drinkers (OR=1.56, 95%CI: 1.17-2.08), compared with people <65 years old, people aged 65-74 years old and ≥75 years old had a higher risk of stroke, the value of OR (95%CI) were 1.88 (1.36-2.59) and 1.97 (1.39-2.80), respectively, compared with people with normal body fat percentage, people whose body fat percentage on high side and people who with high body fat percentage had a higher risk of stroke, the value of OR (95%CI) were 1.71 (1.18-2.48) and 1.74 (1.18-2.56), respectively, people with sleep time >8 h had a higher risk of stroke than those with sleep time of 6-8 h. Conclusion There was a high stroke prevalence among residents in Jiangxi province. Hypertension, drinking, age, BFP and sleep duration were associated with stroke prevalence. Corresponding measures for high-risk population and risk factors should be strengthened to prevent and control the stroke.
