Objective:To study the expression of NF-?Bp65 and bcl-x L gene in pancreatic carcinoma and their clinical significance.Methods:The expressions of NF-?Bp65 and bcl-x L protein in 52 pancreatic carcinoma were studied by immunohistochemistry,and their relationship to clinical pathology were analyzed.Results:The positive rates of NF-?Bp65 protein and bcl-x L protein in pancreatic carcinoma were 63.5% and 73.1% respectively,and which were higher than those of normal pancreatic tissues.The expression of NF-?Bp65 was related to tumor diameter,TNM stage and lymph node metastasis,and had no relation with the extent of differentiation and type of pathology.There was positive correlation between NF-? Bp65 and bcl-x L expression.Conclusion:NF-? Bp65 may be an important oncoprotein,and may have positive regulation on bcl-x L,then promote tumorgenesis.

Objective To investigate the clinical effect of surgical treatment for hilar cholangio-carcinoma. Methods The clinical data of 89 patients with hilar cholangiocarcinoma surgically treated in our hospital were retrospectively analyzed. They were divided into 3 groups: radical resection(group A,n=23),palliative resection (group B,n=44) and external drainage operation (group C,n=22). Complications,operative mortality,survival rate and posttreatment quality of lire were compara-tively analyzed among the 3 groups. Results The rate of complications was significantly higher in group A than in group C (P<0.05). There was no marked difference in operative mortality between group A and group B (P>0.05). The 1-,2-and 3-year survival rates and scoring of quality of life were remarkably higher in group A than in other 2 groups (P<0. 001 and 0. 05). Conclusion Radical re-section of hilar cholangiocarcinoma can improve the long-term survival and significantly enhance quality of life of the patients after operation. For patients receiving unradical resection, palliative surgical man-agement can improve the long-term survival and enhance quality of life.

Objective To design a more reasonable method by comparing three existing injury severity scores for evaluating maxillofacial injury severity according to its features by retrospective analysis. Methods Nine hundred and eighty-four cases with maxillofacial trauma (≤30 days before hospitalization) selected from 1 159 cases were stratified by the number of fractures and the sites of trauma. The injury severity was evaluated with ISS, RFISS and MISS respectively. The results of ISS/RFISS/MISS were compared and analyzed with SPSS software. Results MISS could accurately differentiate single from multiple facial injuries. It was more meaningful for evaluating different sites of facial injury compared with ISS and RFISS. Conclusion MISS can be used to evaluate maxillofacial injury objectively and accurately.

OBJECTIVE: To investigate the clinical and pathological features of solitary pterygoid benign lesions, as well as the treatment and outcome of endoscopic surgery. METHOD: We retrospectively analyzed clinical data of 4 patients with pterygoid benign lesions in our department. High resolution CT and enhanced MRI were performed before the operations, then endoscopic surgeries were carried out under the circumstance of general anesthesia. After a follow-up in 12 months to 48 months, nasal endoscopy and MRI examination were performed. Therefore we are able to understand the situation of operations and postoperative recurrences, and to inquire about the changes of symptoms and the relief of symptoms before and after surgery. RESULT: From the Pathological diagnosis, it showed 2 cases of cystic lesions, 1 case of spindle cell lipoma, 1 case of inflammatory lesion. Postoperative follow up showed scar formation, smooth surface, no recurrence, and no new symptom. Nasal obstruction is relieved after the surgery, and no changes in the sympotoms of headache were observed. CONCLUSION The combination of high resolution CT with enhanced MRI isimportant for ascertaining the location, extent and nature of the pterygoid lesions. Endoscopic surgery is a minimally invasive, safe, and effective method for the treatment of solitary pterygoid benign lesions.

Objective To detect of clostridium perfringens by qPCR in mouse models and a clinical case in order to offer early diagnosis.Methods 40 Kunming mice were randomly grouped and intramuscular injected clostridium perfringens type A in leg 0.1 ml(3.5 × 109cfu/ml or 3.5 × 108cfu/ml or 3.5× 107cfu/ml,diluted with saline),while control group was injected with 9% sodium chloride 0.1ml.The mouse models and a clinical case were detected by qPCR.Results The death rate of 3.5 × 109,3.5 × 108,3.5 × 107cfu/ml and the blank group were 90%,70%,10% and 0% after intramuscular injection for 72 h spectively.The mean Ct values among these groups were 21.21 ±2.69,28.45 ±2.74,32.49 ±2.87 and 0.00 ± 0.00(P ＜ 0.05).The Ct values of the patient were 30.67 and 30.44.Conclusions Cclostridium perfringens could be successful identified with qPCR in mouse models when the mice still did not show any symptoms.

Objective To study the expression of nuclear factor-?Bp65 (NF-?Bp65) in gastric carcinoma and its relationship with vascular endothelial growth factor (VEGF). Methods The expression of NF-?Bp65 and VEGF in 56 gastric carcinomas was detected with immunohistochemistry and compared with benign tissues. Results The positive rates of NF-?Bp65 and VEGF in 56 gastric carcinomas were 62.5% and 76.8% respectively,and which were higher than those of gastric mucosal atypical hyperplasia (33.3% and 44.4%) and the normal gastric mucosa(0 and 8.3%) (P0.05). There was positive correlation between NF-?Bp65 and VEGF expression (r=0.36,P

Objective To analyze the clinical characteristic and provide therapeutic techniques of maxillofacial trauma in the elderly. Methods Geriatric maxillaofacial trauma patients admitted to our hospital from January 1992 to December 2002 was retrospectively reviewed. Data were collected according to etiology, location, comorbidities, associated injuries, therapeutic methods and the outcome. The patients were compared with a control group consisting of 200 young and adult patients admitted at the same period. Results For the 126 geriatric trauma patients, the major causes were traffic accidents(61.1%) and violence assault(25.4%). A large proportion of facial injuries occurred on the lower part of the face. 69.1% of the patients presented with preexisting diseases. Most of the fractures were not treated(35.7%). The length of hospitalization and ICU stay were relatively longer when compared with the control group(P

Objective To evaluate the value of immunofecal occult blood test (IFOBT) as a prognostic indicator in CKD patients with colorectal impairment.Methods A total of 176CKD patients and 180 healthy adults as control were enrolled.Serum biochemistry was measured at baseline and gastrointestinal bleeding was determined by IFOBT.All the CKD patients were followed up for 4.5 years.Renal replacement therapy or death was defined as end-point event.The Logistic regression analysis was used for risk factors.Kaplan-Meier analysis and COX regression model were used for survival analysis.Results The positive rate of IFOBT in CKD patients was significantly higher than healthy control (17％ vs 5.3％,χ2=13.236,P＜0.01).When comparing with IFOBT negitive patients,IFOBT positive patients were older [(62.030±15.544) years old vs (48.660±19.018)years old,P＜0.01],had higher ESR [(71.800±31.657) mu/h vs (57.210±32.712) mm/h,P＜0.05],C-reactive protein [6.230 (3.000～14.148) mg/L vs 3.000 (3.000～6.833)mg/L,P＜0.05],serum creatinine [419.100 (103.200～546.625) μmol/L vs 175.100 (68.150～462.950) μmol/L,P＜0.05],and had lower hemoglobin level [(97.970±20.590) g/L vs (107.170±27.988) g/L,P＜0.05] and eGFR [11.400 (8.671～53.544) ml·min1·(1.73 m2)1 vs 35.274(10.961～82.145) ml·min-1·(1.73 m2)-1,P＜0.01].There was a negative correlation between IFOBT value and eGFR in CKD patients (r=-0.20,P＜0.01).Positive correlations of IFOBT value with age (r=0.175,P＜0.05) and serum creatinine (r=0.171,P＜0.05) were found.Logistic regression and COX regression analysis showed that IFOBT value,eGFR and ESR were important factors that influenced the prognosis of CKD patients.Kaplan-Meier analysis revealed that IFOBT value ＞100μg/L predicted progression of renal function.Conclusions The prevalence of gastrointestinal bleeding disorder is high in patients with CKD.Value of IFOBT independently predicts decline in renal function of CKD patients.

OBJECTIVE: To investigate the long term clinical effect of budesonide treatment in middle meatus for chronic rhinosinusitis(CRS) following endoscopic sinus surgery (ESS). METHOD: A total number of 53 patients with CRS received ESS were divided into two groups according to budesonide treatment: budesonide-treated group with 21 cases (39.6%) and control group with 32 cases (60.4%). Gelatin sponges soaked with 1 ml budesonide suspension were put in middle meatus in budesonide-treated group, while only gelatin sponges were put in middle meatus in control group. Visual analogy score (VAS), sino-nasal outcome test-22 (SNOT-22) and Lund-Kennedy endoscopic scale were carried out before ESS and two years after ESS. RESULT: In budesonide-treated group, there were a statistical difference before and after ESS in the VAS, SNOT-20 and Lund-Kennedy score (P<. 05). In control group, difference was also significant in VAS, SNOT-20 and Lund-Kennedy score before and after ESS (P < 0.05). The VAS gap of post-operative and pre-operative in two groups are significantly different (P<. 05). However, there was no significant difference in the SNOT-20 and Lund-Kennedy endoscopic scale gap before or after the operation between two groups. CONCLUSION It is safe, convenient and practicable to perform budesonide treatment in middle meatus following ESS, which can significantly ease the post-operative discomfort of nose.
