Objective To investigate the efficacy of radiofrequency ablation assisted spleen-preservation for splenic injury.Methods The clinical data of 64 patients with splenic injury who were admitted to the Suining Central Hospital from August 2010 to May 2012 were retrospectively analyzed.Radiofrequency coagulation hemostasis devices were used for stanching bleeding directly.Results Of the 64 patients,35 received radiofrequency ablation assisted splenic bleeding stemosis,and 29 received radiofrequency ablation assisted partial splenectomy.The mean operation time and volume of intraoperative blood loss were (138 ± 48)minutes and 50-400 ml,respectively.Radiofrequency ablation assisted spleen-preservation was successfully carried out in 63 patients.One patient received reoperation (splenic resection) due to hemorrhage 24 hours after operation.Transient rise of temperature was detected in all the patients,and the temperature was back to normal after conventional management.The complication rate was 6.3％ (4/63),l patient was complicated with anastomotic leakage and was cured by reoperation; 1 was complicated with left pleural effusion; 1 was complicated with pulmonary infection,and his temperature was back to normal 4 days later; 1 was complicated with effusion in the fossa of the spleen.Celiac drainage tube drainaged out 10-120 ml liquid in the first day after operation,5-25 ml on the day 2-3,and they were removed on the third day.There was no effusion around the spleens,and the texture of the spleen was even at 2 weeks after operation.The duration of hospital stay was (14 ±4)days (range,8-40 days).The results of B sonography showed that no effusion and necrotic lesions in the spleen,and immune examinations showed that the splenic function was normal.Conclusion Radiofrequency ablation assisted spleen-preservation for splenic injury is safe and easy to manipulate.

Colorectal polyps are eminence lesions that protruded from mucosa into lumen,including adenomatous polyps and non-adenomatous polyps. Early detection and resection of adenoma has significance in prevention of colorectal cancer,and the surveillance afterwards is also crucial. Interval cancer is the colorectal cancer that develops between initial negative colonoscopy or all the polyps having cleared and the next colonoscopy. It is an important duty for endoscopists to reduce the incidence of interval cancer. This article reviewed the advances in studies on surveillance after resection of colorectal adenoma and the development of interval cancer.

0.999). The characteristic masses and detection limits achieved were as follows,as for As,21 pg and 0.13 ?g/L,as for Se,32 pg and 0.33 ?g/L. The recoveries were 96.0%-103.6% for As,98.3%-104.7% for Se and the RSDs were 0.6%-1.7% for As,0.6%-2.8% for Se. Conclusion This method was accurate, simple and sensitive,it is applicable to the determination of trace As and Se in water.

Objective To compare the antineoplastic immunological effects of nanoemulsion-encapsulated MAGE1-HSP70 and SEA(the ratio of MAGE1-HSP70 fusion protein to SEA superantigen was 100∶1)as NE(MHS)vaccine as given in different routes,and try to look for a novel and effective immune route.Methods NE(MHS)was prepared using magnetic ultrasound methods,and the size,the encapsulation rate and the stability of the nanoemulsion vaccine were evaluated.C57BL/6 mice were immunized via p.o.,subcut.,i.v.,or i.p.route.The cellular immunocompetence was detected by ELISpot assay and LDH release assay.The therapeutic and tumor challenge assay were examined too.Results When the vaccine was given orally,the tumor masses formed 28 days after B16-MAGE1 inoculation in mice were markedly bigger than that formed in the mice of the other groups(P

Objective To analyze the laboratory indexes related to type 2 diabetes mellitus(T2DM ) and to explore whether hy‐poglycemia would aggravate the injury of body and development of complication .Methods 27 cases of patients with T2DM from Jan .to Jun .2014 were enrolled in hypoglycemia group ,and 80 patients of diabetes mellitus without hypoglycemia were enrolled in non‐hypoglycemia group .The laboratory indexes were compared between the two groups ,and the relationship between incidence rate of hypoglycemia and levels of glycosylated hemoglobin (HbAc1) were also analyzed ..Results The age ,course of the disease , levels of alanine aminotransferase (ALT ) and serum creatinine (SCr) and urinary protein excretion (Upro ) in the hypoglycemia group were higher than those in the non‐hypoglycemia group ,there were statistical significant differences (P<0 .05);while there was no significant differences in levels of fasting plasma glucose(FPG) and HbA1c ,gender and body mass index(BMI) between the two groups(P>0 .05) .The levels of creatine kinase(CK) ,high sensitivity C‐reactive protein(hs‐CRP) and fibrinogen(FIB) in pa‐tients with T2DM after developing hypoglycemia were higher than those in patients before developing hypoglycemia ,while superox‐ide dismutase(SOD) was lower ,there were statistical significant differences (P<0 .05) .It showed an incomplete inverse correlation between risk of hypoglycemia in patients with T 2DM and levels of HbA1c(P>0 .05) ,at the same time the risk of hypoglycemia tended to be higher in patients with near‐normal level of HbA1c than patients with poor HbA1c control .Conclusion The older , long course of disease and near‐normal levels of HbA1c controled in patients with T2DM may be prone to develop hypoglycemia . Hypoglycemia could aggravate the body injury and speed up the development of complications of T 2DM .

BACKGROUND:Recent studies have proved the presence of adjacent vertebral fractures after percutaneous kyphoplasty, suggesting that cement leakage may be an important reason. OBJECTIVE:To investigate the effect of bone cement amount during percutaneous kyphoplasty on adjacent vertebral endplate using finite element analysis. METHODS: Three-dimensional finite element pathological model of Osteoporotic vertebral compression fracture was established using finite element analysis, and 10%, 20% and 30% volume of bone cement were filed, respectively. Then the adjacent vertebral endplate stress under the axial compression, anteflexion and rear protraction were analyzed. RESULTS AND CONCLUSION: Compared with that before operation, the adjacent vertebral endplate stress increased with the increase in filed bone cement volume, suggesting that the increased amount of bone cement wil lead to the increasing of adjacent vertebral re-fractures.

BACKGROUND:The age, complication, injury to operation time, and pain level are important factors that affect patients with postoperative mortality, but many scholars disagree. Factors affecting death in elderly patients after femoral head replacement stil need further study. OBJECTIVE:To observe factors related to the survival status of elderly patients within 1 year after receiving femoral head replacement. METHODS:A total of 96 elderly patients receiving femoral head replacement at Department of Orthopedics, the First Affiliated Hospital of Xi’an Jiaotong University from January 2011 to January 2014 were selected. On admission, patients’ age, sex, time from injury to operation, injury to admission time, pain classification, admission hemoglobin, serum albumin content of admission, admission lymphocyte count, and the amount of blood transfusion and preoperative complications were recorded. Fisher test was used to analyze the factors affecting survival status within 1 year after replacement in patients with femoral head replacement using one-way analysis of variance. Multivariate Cox test was utilized to perform multi-factor analysis. RESULTS AND CONCLUSION: The injury to hospital time was > 5 days. Pain classification was grades III and IV. The hemoglobin content was < 120 g/L on admission. The volume of blood transfusion was > 1 000 mL. Serum albumin content was < 35 g/L, which was associated with the increased mortality (P < 0.05). The mortality was significantly higher in patients with more than 86 years old than in patients with 70-85 years old (P < 0.05). The mortality of patients with the time from injury to operation > 7 days was significantly higher than patients with the time from injury to operation < 7 days (P < 0.05). The serum albumin content < 35 g/L and grades III and IV of ASA classification were factors related to patient’s death (P < 0.05). Results confirm that the risk factors for survival status within 1 year of femoral head replacement contain intraoperative volume of blood transfusion, admission to operation time, hemoglobin content, and grading of pain.
