Objective To explore ultrasound performances and misdiagnostic causes of aggressive fibromatosis (AF).Methods Ultrasound performance and misdiagnostic causes of 45 patients (47 tumors) with AF confirmed by histopathology were analyzed retrospectively.Results Of 45 patients,ultrasound showed lesions of varying size,and the maximum diameter of 36 masses (36/47,76.60％) were more than 3 cm;37 masses (37/47,78.72％) were irregular pale leaf;45 masses (45/47,95.74％) had no complete capsule;45 masses (45/47,95.74％) were shown as interogeneous internal echo mixed with hyperechoic area in the hypoechoic internal;29 cases were diagnosed correctly,16 cases were misdiagnosed,the diagnostic accordance rate was 64.44％ (29/46).Conclusion AF has certain ultrasonic characteristics.Combined with the patient's medical history and physical sign,ultrasound can significantly improve the preoperative detection rate and diagnostic accuracy of AF.

Objective To evaluate the efficacy of surgical repair for non-circumferential defect of bile duct in Mirizzi syndrome.Method The clinical data of 32 patients with Mirizzi syndrome with non-circumferential defect of bile duct were repaired using the patient's own tissues such as gallbladder pedicle flap,umbilical venous flap and omental flap.Results All the patients were operated success fully.There was no operative mortality.The defects in the bile duct were repaired using gallbladder pedicle flap in 25 patients,umbilical venous flap in 5 patients and omental flap in 2 patients.There were 2 patients who developed postoperative complications.There was one postoperative bile leakage in a patient who was repaired using an umbilical venous flap.The other complication was residual bile duct stones.The patient with postoperative bile leakage was drained through a drainage tube which was removed after 7 days.The residual bile duct stones were removed by endoscopy through a T-tube sinus after 9 months.All patients were confirmed by T-tube cholangiography after 9 to 12 months to have no stones,bile duct stenosis or any other abnormalities.The T-tube was then removed.All patients were followed -up for 1 to 5 years.All patients had no cholangitis,abdominal pain,jaundice or fever.Conclusions Using the patients' own tissues such as gallbladder pedicle flap,umbilical venous flap and omental flap to surgical repair the defect in the bile duct of patients with Mirizzi syndrome was effective.This surgical treatment is a good choice.

Objective To analyze characteristics of severe liver trauma and efficacy of different surgical procedures. Methods Clinical data of 109 patients with severe liver trauma treated in the recent 10 years were retrospectively analyzed. Debriding suture was performed in 32 patients, gauze tamponade in 5, debridement hepatectomy in 59 and anatomical hepatectomy in 13 patients. Results In all the 109 patients, 92 were cured and 17 died. The dead patients included 3 with grade Ⅲ trauma,9 with grade Ⅳ trauma, and 5 with grade V trauma. Among the dead patients, there were 3 patients with simple liver injury (17.6%) and 14 with associated injury (82.4%). Conclusion Right hepatic serious damage is the main type of severe liver trauma and is always complicated with associated injury and needs emergency treatment. Application of the most appropriate surgical approach according to the traumatic condition is important to promote the successful rate of treatment.

Objective To exPlore the efficacy of nutritional interVention in Patients with chronic obstructiVe Pulmonary disease (COPD) and malnutrition risks. Methods From Jan. ,2008 to Dec. ,2012,829 COPD Patients with NRS2002 score≥3 in Qinzhou Second PeoPle's HosPital were enrolled in this study. Patients were randomized into control grouP (254 cases) and treatment grouP (575 cases) by random numerical table of SPSS 13. 0 statistic software. Patients without contraindication to enteral nutrition were giVen enteral nutrition suPPort,while those with contraindication to enteral nutrition were giVen Parenteral nutrition suPPort. Patients in the treatment grouP receiVed intensiVe suPPort with fortified nutrition,whereas Patients in the control grouP receiVed routine nutrition treatment. All other treatment methods were the same between the two grouPs. TelePhone follow_uP lasted for 3 years in both grouPs after discharge. Patients in the treatment grouP with NRS2002 score≥3 were giVen guidance on nutrition food intake. No nutrition guide was giVen to the control grouP. Times of acute attack,times and duration of mechanical Ventilation,mortality rate,and NRS2002 score three years after the treatment were comPared between the two grouPs. Data were analyzed by multi_factor Logistic regression analysis to understand the nutritional factors of COPD Patients affecting their mortality rate. Results After 3 years of follow_uP,times of acute attack,times and duration of mechanical Ventilation were lower in the treatment grouP than in the control grouP. Mortality rate was significantly lower in the treatment grouP (0. 696%) than the control grouP (4. 724%). After treatment,NRS2002 score was PositiVely correlated with mortality rate of COPD Patients with malnutrition risks. Conclusion For the COPD Patients with malnutrition risks, actiVe nutritional interVention can imProVe their nutrition status ( lower NRS2002 score) ,increase the number of resPiratory muscles to alleViate anoxia,enhance cellular immune function, and thus imProVe their Prognosis.

Objective To explore the effect and mechanism of L-arginine on fetal growth restriction by observing the expression of Bcl-2 and Bax in placenta.Methods Sixty patients with FGR were chosen,among which 30 cases who were treated with conventional ways were as convention group,and the other 30 cases who were treated with L-arginine were as L-arginine group.The birth weight and perinatal fetus outcome were detected.The central tissue of placenta got within 10 min after delivery were fixed by 100 g/L formaldehyde and embed by pa-raffin wax to observe the expression of Bcl-2 and Bax using immunohistochemistry.SPSS 11.5 software was used to analyze the data.Results Compared with convention group,the birth weight of L-arginine group was higher(P

Objective To investigate the modulation of EPCs by interleukin 1β (IL-1β) and p38 mitogen activated protein kinase (p38MAPK) and the pathogenesis resulting from their dysdifferenfiation after trauma.Method Thirty pigs were divided into a control group (n = 15) and a multiple organ dysfimction syndrome (MODS) group (n = 15), the latter of which were subjected to a "two-hit" injury including hemon'hagic shock and endotoxemia. Phosphorylation of p38MAPK in peripheral blood mononuclear cells was monitored by western blotting. The concentration of IL-1β in peripheral blood plasma was determined by ELISA and the numbers of EPCs with FCM in peripheral blood plasma were monitored. The morbidity rates in the two groups were compared by chi square test. The levels of phosphorylation of p38MAPK in peripheral blood mononuclear cells, the concentmtions of IL-1β in peripheral blood plasma and the numbers of EPCs in the peripheral blood were compared between groups using with Student's t lest. Results The level of p38MAPK phosphorylation was more augmented and the concen-tration of IL-1β higher in peripheral blood mononuelear cells and plasma from MODS pigs compared with those from control pigs; nevertheless the mauler of EPC conspicuously decreased in the peripheral blood (P <0.01). The morbidity rate in the MODS group was much higher than that in the control group (P < 0.01). There were fewer EPCs in the peripheral blood of animals in group M than in the peripheral blood of animals in group C (P <0.01). Conclusions p38MAPK phosphorylation is important for the pathogenesis of MODS. p38MAPK phospho-rylation might cause the concentration of IL-1β in the peripheral blood plasma to rise and could cause a drop in the numbers of EPCs, thereby aggravating the inflanmmatory reaction in MODS.

Objective To evaluate the impact of chemotherapy compliance on the therapeutic efficacy of induction chemotherapy plus concurrent chemoradiotherapy versus induction chemotherapy plus radiotherapy alone for patients with locally advanced nasopharyngeal carcinoma (NPC). Methods Based on intention to treat analysis (ITT) for 400 patients, 314 patients were analyzed by per protocol (PP) analysis. The patients were divided into induction chemotherapy plus concurrent chemoradiotherapy group (IC/CCRT, 127 patients) or induction chemotherapy plus radiotherapy group (IC/RT, 187 patients). The patients who completed 2 cycles of induction chemotherapy and at least 2 cycles of concurrent chemotherapy in the IC/CCRT group and the patients who completed 2 cycles of induction chemotherapy in the IC/RT group were analyzed. Radiotherapy was given by two-dimensional technique with γ-ray, X-ray and electron beams. The chemotherapy regimen was FUDR plus carboplatin for induction chemotherapy and carboplatin alone for concurrent chemotherapy. Results The follow-up rate was 96.2%. 295 patients were followed to at 3 years. Based on PP analysis, Grade 3/4 toxicity was found in 23.6% of the patients in IC/CCRT group and 13.4% in the IC/RT group (χ~2 =5,50,P=0.019). No grade 4 toxicity was found in the IC/RT group. The median follow-up time was 3.9 years, and no significant difference was found between the two groups in 3-year overall survival (78.1% : 84.6% ;χ~2 = 0. 61, P =0. 435), disease-free survival (74.3 % : 70.1% ;χ~2= 0. 12, P= 0.731), Iocoregional relapse-free survival (89.7% : 89.5% ; χ~2= 0. 10, P= 0.748), or distant metastasis-free survival (78.9%:76.5% ;χ~2=0.05,P=0.825). Conclusions With more severe toxicities, the IC/CCRT regimen does not improve the overall survival in locally advanced NPC patients compared with the IC/RT regimen.
