[Method] Through ar- tificial injection of allantoic liquid containing ILTV into chickens to induce infectious laryngotracheitis, the clinical symptoms in infected chickens were observed; tissues of trachea, lungs, heart, liver, kidney and spleen were collected from dead chickens, and prepared into paraffin sections, followed by histopathological observation under a microscope. [Results] This disease occured in the inoculated chickens 3d later, with a morbidity rate of 95%. The main symptoms were dyspnea, asthma and coughing up of bloody exudate; yellowish-white pseudomembrane was observed on dissected larynx trachea; swelling, haemorrhage, and further erosion were observed on the in- fected tracheal mucosa, resulting in death of chickens, with the mortality rate of 25%; histopathological observation showed that parenchymal organs exhibited exuda- tive inflammation; swelling, degeneration, necrosis and shedding of epithelial cells were observed; disturbance of blood circulation occured.[Conclusion] This study pro- vides reference bases for the treatment of ILT.展开更多

METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ , high grade including tumors with microinvasion). RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors. CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy.展开更多

Over half of patients with advanced bile duct cancer present with unresectable malignancies and their prognosis has been very poor even after curative resections. Although there has been a need to diagnose bile duct cancer at its eady stage, it has been a difficult goal to achieve due to our lack of knowledge regarding this disease entity. Early bile duct cancer may be defined as a carcinoma whose invasion is confined within the fibromuscular layer of the extrahepatic bile duct or intrahepatic large bile duct without distant metastasis irrespective of lymph node involvement. Approximately 3%-10% of resected bile duct cancers have been reported to be early cancers in the literature. The clinicopathological features of patients with early bile duct cancer differ from those of patients with advanced bile duct cancer, with more frequent asymptomatic presentation, characteristic histopathological findings, and excellent prognosis. This manuscript is organized to emphasize the need for convening an international consensus to develop the concept of early bile duct cancer.展开更多

METHODS: From January 2001 to December 2006, 487 patients with histologically confirmed primary gas- tric adenocarcinoma were diagnosed with stage 11 gas- tric cancer according to the new 7th edition American Joint Committee on Cancer stage classification at the Department of Gastric Cancer and Soft Tissue Surgery, Fudan University Shanghai Cancer Center. All patients underwent curative gastrectomy with standard lymph node (LN) dissection. Fifty-one patients who died in the postoperative period, due to various complications or other conditions, were excluded. Clinicopathologicalfindings and clinical outcomes were analyzed. Patients were subdivided into four groups according to the status of LBVI and LN metastases. These four patient groups were characterized with regard to age, sex, tumor site, pT category, tumor grading and surgical procedure (subtotal resection vs total resection), and compared for 5-year overall survival by univariate and multivariate analysis. RESULTS: The study was composed of 320 men and 116 women aged 58.9 ± 11.5 years (range: 23-88 years). The 5-year overall survival rates were 50.7% and the median survival time was 62 too. Stage Ⅱ a cancer was observed in 334 patients, including 268 T3N0, 63 T2N1, and three TIN2, and stage Ⅱb was observed in 102 patients, including 49 patients T3N1, 51 T2N2, one TIN3, and one T4aN0. The incidence of LBVI was 28.0% in stage II gastric cancer with 19.0% (51/269) and 42.5% (71/167) in LN-negative and LN- positive patients, respectively. In 218 patients (50.0%), there was neither a histopathologically detectable LBVI nor LN metastases (LBVI-/LN-, group I); in 51 patients (11.7%), LBVI with no evidence of LN me- tastases was detected (LBVILN-, group 11). In 167 patients (38.3%), LN metastases were found. Among those patients, LBVI was not determined in 96 patients (22.0%) (LBVI-γLN, group Ⅲ), and was determined in 71 patients (16.3%) (LBVI+LN+, group Ⅳ). Correla- tion analysis showed that N category and the number of positive LNs were significantly associated with the presence of LBVI (P 〈 0.001). The overall 5-year sur- vival was significantly longer in LN-negative patients compared with LN-positive patients (56.1% vs 42.3%, P = 0.015). There was a significant difference in the overall 5-year survival between LBVI-positive and LBVI- negative tumors (39.6% vs 54.8%, P = 0.006). Overall 5-year survival rates in each group were 58.8% ( Ⅰ), 45.8% (Ⅱ), 45.7% (Ⅲ) and 36.9% (Ⅳ), and there was a significant difference in overall survival between the four groups (P=-0.009). Multivariate analysis in stage 11 gastric cancer patients revealed that LBVI in- dependently affected patient prognosis in LN-negativepatients (P = 0.018) but not in LN-positive patients (P = 0.508). CONCLUSION: In LN-negative stage 11 gastric cancer patients, LBVI is an additional independent prognostic markeF, and may provide useful information to identify patients with poorer prognosis.展开更多

The aim of this study therefore was to prospectively evaluate the histological findings and the impact of Hpyloriinfection on a group of symptomatic patients with NERD. METHODS:Fifty consecutive patients were prospectively evaluated for symptoms compatible with GORD.In all cases, routine endoscopy and lugol directed biopsies were performed and assessed histologically in a blinded manner. RESULTS:The overall prevalence of Hpyloriinfection was 70%.Twenty-nine patients out of 50 (58%) were NERD patients.No statistical significance was observed between the H pyloristatus and NERD.The remaining 21 (42%) were diagnosed as follows:13 (26%),6 (12%),2(4%) with esophagitis grade A,B and C respectively.A statistically significant correlation was observed between the Hpylori+ and esophagitis grade A,as well as between Hpylori-and grade B.Biopsies from 2 patients were not included because of insufficient materials.Histologically,a basal zone hyperplasia was found in 47 (97.91%) patients,alterations of glycogen content in 47 (97.91%),papillae elongation in 33 (68.75%), blood vessels dilatation in 35(72.91%),chronic inflammation in 21 (43.75%),infiltration with eosinophils,neutophils and T-lymphocytes in 4 (8.33%),6 (12.5%) and 39 (81.25%) respectively.No correlation was observed between the Hpyloristatus and the histological parameters studied either in NERD or GERD. CONCLUSION:Histological assessment can not differentiate symptomatic patients with erosive versus non-erosive reflux disease.Moreover,Hpyloriinfection may not act as an important factor in patients with NERD.展开更多

Methods: Cyclin D1 and p27kip1 protein were detected by immunohistochemical En Vision method in 43 BACs. Results: The positivity of cyclin D1 in BAC was 65.1% (28/43), which was significantly higher than that in normal pulmonary tissue (0/13), P<0.01. No statis-tically significant association was found between cyclin D1 expression data and sex, age, tobacco-use history, histologic subtype (mucinous vs nonmucinous), stromal fibrosis, lymph node metastasis, clinical stage or postoperative survival period (P>0.05), while cyclin D1 expression was found to be negatively correlated with tumor size (P<0.05). The positivity of p27kip1 in BACs was 51.2% (22/43), significantly lower than that in normal pulmonary tissue (12/13), P<0.01. p27kip1 expression level was not associated with sex, age, tobacco-use history, tumor size or histologic subtype (P>0.05), but was negatively correlated with stromal fibrosis, lymph node metastasis and clinical stage (P<0.05); and positively associated with postoperative survival period (P<0.01). The survival rate of p27kip1 positive group was significantly higher than that of p27kip1 negative group (P<0.01). No statistically significant correlation was found between cyclin D1 and p27kip1 expres-sion. Conclusions: Increased cyclin D1 expression and decreased p27kip1 expression are related to the pathogenesis of BAC; decreased p27kip1 expression is associated with metastasis progression; immunodetection of p27kip1 is useful for assessment of prognosis.展开更多

The study was conducted by the Estonian work group of the International Controller Association ICV (internationaler controller verein). The methodology and controlling questionnaire were the same, which were used by the German work group of ICV in 2006. The mentioned questionnaire was also worked out in Germany by Otto Beisheim School of Management. The authors compared the results of both studies Cultural differences and their impact on the tasks of controllers were also scrutinized. The results of the research indicate that the tasks of Estonian controllers are strictly fixed with procedure documents, which leaves very lithe room lbr independence and initiative. Usually, they are not involved in the strategic planning and goal setting. The final conclusion is that the sustainability function of controlling is much more on the background compared to other functions of controlling, but in the future the role of this function is expected to increase展开更多

文摘[Objective] This study aimed to investigate the histopathological changes in chickens artificially infected with infectious laryngotracheitis(ILT). [Method] Through ar- tificial injection of allantoic liquid containing ILTV into chickens to induce infectious laryngotracheitis, the clinical symptoms in infected chickens were observed; tissues of trachea, lungs, heart, liver, kidney and spleen were collected from dead chickens, and prepared into paraffin sections, followed by histopathological observation under a microscope. [Results] This disease occured in the inoculated chickens 3d later, with a morbidity rate of 95%. The main symptoms were dyspnea, asthma and coughing up of bloody exudate; yellowish-white pseudomembrane was observed on dissected larynx trachea; swelling, haemorrhage, and further erosion were observed on the in- fected tracheal mucosa, resulting in death of chickens, with the mortality rate of 25%; histopathological observation showed that parenchymal organs exhibited exuda- tive inflammation; swelling, degeneration, necrosis and shedding of epithelial cells were observed; disturbance of blood circulation occured.[Conclusion] This study pro- vides reference bases for the treatment of ILT.
文摘AIM: To investigate the clinicopathological features of intraductal neoplasm of the intrahepatic bile duct (INihB). METHODS: Clinicopathological features of 24 cases of INihB, which were previously diagnosed as biliary papillomatosis or intraductal growth of intrahepatic biliary neoplasm, were reviewed. Mucin immunohistochemistry was performed for mucin (MUC)1, MUC2, MUC5AC and MUC6. Ki-67, P53 and β-catenin immunoreactivity were also examined. We categorized each tumor as adenoma (low grade), borderline (intermediate grade), and malignant (carcinoma in situ , high grade including tumors with microinvasion). RESULTS: Among 24 cases of INihB, we identified 24 tumors. Twenty of 24 tumors (83%) were composed of a papillary structure; the same feature observed in intraductal papillary neoplasm of the bile duct (IPNB). In contrast, the remaining four tumors (17%) showed both tubular and papillary structures. In three of the four tumors (75%), macroscopic mucin secretion was limited but microscopic intracellular mucin was evident. Histologically, 16 tumors (67%) were malignant, three (12%) were borderline, and five (21%) were adenoma. Microinvasion was found in four cases (17%). Immunohistochemical analysis revealed that MUC1 was not expressed in the borderline/adenoma group but was expressed only in malignant lesions (P = 0.0095). Ki-67 labeling index (LI) was significantly higher in the malignant group than in the borderline/adenoma group (22.2 ± 15.5 vs 7.5 ± 6.3, P < 0.01). In the 16 malignant cases, expression of MUC5AC showed borderline significant association with high Ki-67 LI (P = 0.0622). Nuclear expression of β-catenin was observed in two (8%) of the 24 tumors, and these two tumors also showed MUC1 expression. P53 was negative in all tumors. CONCLUSION: Some cases of INihB have a tubular structure, and are subcategorized as IPNB with tubular structure. MUC1 expression in INihB correlates positively with degree of malignancy.

文摘We report 2 cases of pancreatic endocrine tumors that caused obstruction of the main pancreatic duct(MPD).A 49-year-old asymptomatic man was referred to our institution because dilation of the MPD was revealed by abdominal ultrasonography(US).No tumor was detected by endoscopic ultrasonography,computed tomography(CT),and magnetic resonance imaging(MRI).The diameter of the MPD was > 20 mm at the body,and no dilation was noted at the head.Although malignancy was not confirmed through cytology or imaging,pancreatic cancer was strongly suspected.Pancreaticoduo-denectomy was performed.Pathological and immunohistochemical examination revealed a 5 mm × 3 mm serotonin-positive endocrine tumor.Fibrosis was present around the MPD and seemed to cause stricture.A 32-year-old asymptomatic man had elevated serum amylase,and US demonstrated dilation of the MPD.No tumor was detected by CT and MRI.Pancreatic cancer was suspected due to stricture and dilation of the MPD.Pancreatectomy of middle part of pancreas was performed.Pathological and immunohistochemical examination revealed a serotonin-positive endocrine tumor sized 5 mm × 4 mm.We report 2 cases of serotonin-positive pancreatic endocrine tumors that caused stricture of the MPD in spite of the small size of the tumor.
文摘Littoral-cell angioma(LCA), a primary angioma which clinically belongs to splenic hemangioma, can be mostly found in normal spleen red sinus shore cells of reticuloendothelial cell system. The cells of LCA strongly express endothelial and tissue cell associated antigens that indicate a dual differentiation characteristic; whereas only endothelial cell markers are positive in normal spleen red sinus shore cells. Diagnosis of LCA relies on histopathology. Regular follow-up is needed to monitor recurrence and metastasis.
文摘AIM: To determine the prognostic value of lymphatic and/or blood vessel invasion (LBVI) in patients with stage 11 gastric cancer. METHODS: From January 2001 to December 2006, 487 patients with histologically confirmed primary gas- tric adenocarcinoma were diagnosed with stage 11 gas- tric cancer according to the new 7th edition American Joint Committee on Cancer stage classification at the Department of Gastric Cancer and Soft Tissue Surgery, Fudan University Shanghai Cancer Center. All patients underwent curative gastrectomy with standard lymph node (LN) dissection. Fifty-one patients who died in the postoperative period, due to various complications or other conditions, were excluded. Clinicopathologicalfindings and clinical outcomes were analyzed. Patients were subdivided into four groups according to the status of LBVI and LN metastases. These four patient groups were characterized with regard to age, sex, tumor site, pT category, tumor grading and surgical procedure (subtotal resection vs total resection), and compared for 5-year overall survival by univariate and multivariate analysis. RESULTS: The study was composed of 320 men and 116 women aged 58.9 ± 11.5 years (range: 23-88 years). The 5-year overall survival rates were 50.7% and the median survival time was 62 too. Stage Ⅱ a cancer was observed in 334 patients, including 268 T3N0, 63 T2N1, and three TIN2, and stage Ⅱb was observed in 102 patients, including 49 patients T3N1, 51 T2N2, one TIN3, and one T4aN0. The incidence of LBVI was 28.0% in stage II gastric cancer with 19.0% (51/269) and 42.5% (71/167) in LN-negative and LN- positive patients, respectively. In 218 patients (50.0%), there was neither a histopathologically detectable LBVI nor LN metastases (LBVI-/LN-, group I); in 51 patients (11.7%), LBVI with no evidence of LN me- tastases was detected (LBVILN-, group 11). In 167 patients (38.3%), LN metastases were found. Among those patients, LBVI was not determined in 96 patients (22.0%) (LBVI-γLN, group Ⅲ), and was determined in 71 patients (16.3%) (LBVI+LN+, group Ⅳ). Correla- tion analysis showed that N category and the number of positive LNs were significantly associated with the presence of LBVI (P 〈 0.001). The overall 5-year sur- vival was significantly longer in LN-negative patients compared with LN-positive patients (56.1% vs 42.3%, P = 0.015). There was a significant difference in the overall 5-year survival between LBVI-positive and LBVI- negative tumors (39.6% vs 54.8%, P = 0.006). Overall 5-year survival rates in each group were 58.8% ( Ⅰ), 45.8% (Ⅱ), 45.7% (Ⅲ) and 36.9% (Ⅳ), and there was a significant difference in overall survival between the four groups (P=-0.009). Multivariate analysis in stage 11 gastric cancer patients revealed that LBVI in- dependently affected patient prognosis in LN-negativepatients (P = 0.018) but not in LN-positive patients (P = 0.508). CONCLUSION: In LN-negative stage 11 gastric cancer patients, LBVI is an additional independent prognostic markeF, and may provide useful information to identify patients with poorer prognosis.

文摘Purpose: To investigate the relationship between expression of cell cycle-related protein cyclin D1, p27kip1 and the pathogenesis of bronchioloalveolar carcinoma (BAC) and the value of prediction of prognosis. Methods: Cyclin D1 and p27kip1 protein were detected by immunohistochemical En Vision method in 43 BACs. Results: The positivity of cyclin D1 in BAC was 65.1% (28/43), which was significantly higher than that in normal pulmonary tissue (0/13), P<0.01. No statis-tically significant association was found between cyclin D1 expression data and sex, age, tobacco-use history, histologic subtype (mucinous vs nonmucinous), stromal fibrosis, lymph node metastasis, clinical stage or postoperative survival period (P>0.05), while cyclin D1 expression was found to be negatively correlated with tumor size (P<0.05). The positivity of p27kip1 in BACs was 51.2% (22/43), significantly lower than that in normal pulmonary tissue (12/13), P<0.01. p27kip1 expression level was not associated with sex, age, tobacco-use history, tumor size or histologic subtype (P>0.05), but was negatively correlated with stromal fibrosis, lymph node metastasis and clinical stage (P<0.05); and positively associated with postoperative survival period (P<0.01). The survival rate of p27kip1 positive group was significantly higher than that of p27kip1 negative group (P<0.01). No statistically significant correlation was found between cyclin D1 and p27kip1 expres-sion. Conclusions: Increased cyclin D1 expression and decreased p27kip1 expression are related to the pathogenesis of BAC; decreased p27kip1 expression is associated with metastasis progression; immunodetection of p27kip1 is useful for assessment of prognosis.
文摘This paper reviews the literatures of the traditional and the modem organizational model to generalize their categories, features and faults. Based on the unification of the Chinese traditional culture and the “YIN and YANG” principles, it discusses how to understand the hypotheses of the organizational models, analyzes the traditional and the leading models, and puts forward two hypotheses, the fixed structure and the flexible structure of organizations.

文摘Aiming to the deficiency of safety management measure,established simulation model about firm's safety management capability(FSMC) based on organizational learning theory.The system dynamics(SD) method was used,in which level and rate system,vari- able equation and system structure flow diagram was concluded.Simulation model was verified from two aspects: first,model's sensitivity to variable was tested from the gross of safety investment and the proportion of safety investment;second,variables dependency was checked up from the correlative variable of FSMC and organizational learning.The feasibility of simulation model is verified though these processes.
文摘Objective: The aim of this study was to evaluate the recent efficacy and adverse reactions of recombinant human endostatin (Endostar) plus chemotherapy in the treatment of advanced malignancies. Methods: One hundred and seventeen cases of advanced malignancies were diagnosed and confirmed by histopathological examination, patients were treated with Endostar combined with chemotherapeutic drugs with no cross-resistance. Evaluate the efficacy and adverse reactions after finished two cycles of combination therapy. Results: All the 117 cases of patients were evaluated according to relevant standards, and there were 12 cases of complete remission (CR), 30 cases of partial remission (PR), 58 cases of stable disease (SD), 17 cases of progressive disease (PD). The response rate (RR) was 35.8%, disease control rate (DCR) was 85.4%. Conclusion: The protocol of Endostar combined with chemotherapy could improve the quality of life of patients with malignances, it also has the advantage of low toxicity. Considering the time span of the study, the long-term efficacy remains to be observed.

文摘This paper focuses on the functions of controlling in Estonia and Germany, The analysis based on the study carried out in Estonian enterprises in 2008. The study was conducted by the Estonian work group of the International Controller Association ICV (internationaler controller verein). The methodology and controlling questionnaire were the same, which were used by the German work group of ICV in 2006. The mentioned questionnaire was also worked out in Germany by Otto Beisheim School of Management. The authors compared the results of both studies Cultural differences and their impact on the tasks of controllers were also scrutinized. The results of the research indicate that the tasks of Estonian controllers are strictly fixed with procedure documents, which leaves very lithe room lbr independence and initiative. Usually, they are not involved in the strategic planning and goal setting. The final conclusion is that the sustainability function of controlling is much more on the background compared to other functions of controlling, but in the future the role of this function is expected to increase
