Objective To explore the lymph nodes (LN) metastasis characters of the endometrial carcinoma and its relation with the patients' prognosis. Methods A retrospective study was carried out on 227 cases of endometrial carcinoma who admitted to our department and underwent LN excision from Jul. 2000 to Feb. 2008. Results Among 227 cases who underwent pelvic LN excision, there were 22 cases (9.7%) presented LN metastasis. There were 12 cases with positive external iliac LN from 20 cases of patients with data in LN grouping. Para-aortic LN excision was carried out on 138 patients. There were 6 cases with positive para-aortic LN, 5 cases of them together with pelvic LN metastasis. Those patients with cervix involvement, annex metastasis, deep myometrium infiltration, grade 2-3 and negative estrogen receptor occurred pelvic LN metastasis more frequently than the others ( P < 0. 05 ). Among the 6 cases with positive para-aortic LN, there were 3 cases ( 3/6) with deep myometrium infiltration. For those whose paraaortic LN was negative, it was only 16. 7% (22 cases). But there were no difference statistically between them ( P> 0. 05 ). There were significant difference in 3 years disease-free survival rate between patients with positive pelvic LN or negative pelvic LN [(81. 8 ± 8. 2)% vs ( 97. 4 ± 1. 2 ) % , P = 0. 004]. While there were not significant difference in 3 years disease-free survival rate between patients with positive para-aortic LN or negative para-aortic LN [100% vs ( 96. 7 ± 1. 6) % , P > 0. 05]. Single factor analysis showed that the age more than 50 years, annex metastasis and pelvic LN metastasis related with the recurrence (P <0. 01). But cervix involvement, deep myometrium infiltration, para-aortic LN metastasis, pathology type, tumor grade and estrogen receptor did not relate with the recurrence ( P > 0. 05 ). Cox regression analysis showed that annex metastasis and the age of patients were independent risk factors affecting the recurrence ( P = 0. 011, P = 0. 025 ). Conclusions The most common site of pelvic LN metastasis is the external iliac LN for endometrial carcinoma patients. The patients with positive para-aortic LN always accompanied pelvic LN metastasis. Those patients with cervical involvement, annex metastasis, deep myometrium infiltration, poor differentiation and negative estrogen receptor be more likely exist pelvic LN metastasis. Pelvic LN metastasis may affect the prognosis of endometrial carcinoma patients.

ObjectiveTo investigate the role of overexpressed proinflammatory cytokines in the pathogenesis of cerebral palsy (CP).MethodsLevels of tumor necrotic factor-α (TNF-α) and interleukin-6 (IL-6) in serum of 31 CP children, 20 healthy children (as controls), 37 neonates with CP risk factors such as hypoxic-ischemic injury and/or perinatal infection, and 20 healthy neonates (as controls) were measured by enzyme-linked immunosorbent assays (ELISA) retrospectively.ResultsLevels of TNF-α and IL-6 of CP children and neonates with CP risk factors were significantly higher than that of healthy controls (P<0.05). TNF-α level of CP children was significantly higher than that of neonates with CP risk factors (P<0.05), but there was no significant difference in IL-6 level between two groups.ConclusionOverexpressed proinflammatory cytokines play an important role in the pathogenesis of CP and may be an independent risk factor of CP.

Objective To extract Xinjiang Uyghur medicine image features and analyze the features; To investigate the image classification effect of the researched features; To find the suitable features for Xinjiang Uyghur medicine image classification; To lay the foundation for content-based medical image retrieval system of Xinjiang Uyghur medicine images.Methods The flowers and leaves of Xinjiang Uyghur medicine were treated as the research objects. First, images were under preprocessing. Then color and textural features were extracted as original features and statistics method was used to analyze the features. Maximum classification distance was used to analyze the main features obtained from image classification. At last, the classification ability of features was evaluated by Bayes discriminant analysis.Results Color and textural features were selected and classified. The correct classification rate of flower images was 85% and the correct classification rate of leaf images was 62%. The classification effect of flower images used by selected features was better than classification effect of original feature.Conclusion Compared with the classification of original features, the classification accuracy of flower medicine is higher through selected features. This research can lay a certain foundation for the further researches on Xinjiang Uyghur medicine images and the improvement of feature extraction methods.

Objective To investigate the clinical and pathological characteristics of normotensive pheochromocytomas ( NP) . Methods This retrospective study included 97 patients with a pathological diagnosis of pheochromocytoma at the Drum Tower Hospital Affiliated to Nanjing University Medical School during January 2004 to December 2013. All available clinical, biochemical, and radiological records were reviewed in these patients who were then categorized into hypertensive pheochromocytomas (HP) (n=64) and NP (n=33) groups. 97 cases of Adrenal Gland Scale Score of pheochromocytoma were examined, including tissue microscopic pathology assessment, ki67 and phenylethanolamine-N-methyltransferase ( PNMT ) immunohistochemistry and catecholamine type. Biochemical examinations of 95 subjects with primary hypertension ( PH) were recorded for comparative study. Results The patients with NP showed lower proportion of clinical triad than HP, inapparent metabolic disorders, and lower urinary catecholamine levels than HP, but showed higher results than primary hypertension. The weight of tumor was positively correlated with 24 hour urinary norepinephrine level in patients with HP(Y=1. 376+0. 653X,R2=0. 118, P=0. 028), but not in patients with NP;and the size or diameter of the tumor was negatively correlated with PNMT immunohistochemistry in patients with NP(Y=0. 940-0. 356X, R2=0. 494, P=0. 005), but not in patients with HP, indicating that NP may be misdiagnosed clinically. Conclusion Patients with NP have distinct clinical, biochemical, and pathological phenotypes; the phenotypic changes are closely related with the expression levels of catecholamine pathway products during the occurrence and development of the tumors.
