Objective To study the expression of high molecular weight cytokeratin (CK34βE12) in breast carcinoma and the relationship between the high molecular weight cytokeratin expression and patient's prognosis. Methods We detected the high molecular weight cytokeratin expression in 100 patient's of breast cancer tissues and paracancerous breast tissue in 30 cases immunohistochemically. The relationship between the expression of high molecular weight cytokeratin in breast cancer tissues and age, menstrual status, estrogen receptor expression, progesterone receptor expression, histology grading, TNM staging, pathology type, and patient survival was analyzed. Results (1) There was no significant correlation between high molecular weight cytokeratin expression of breast -cancer tissues and age, menstrual status, estrogen receptor expression, progesterone receptor expression (all P>0.05). But the correlation was statistically significant between that expression and histology grading, TNM staging, pathology category (all P<0.05). (2) By univariate analysis, the 5-year disease-free survival rate in patients with negative expression was lower than those with positive expression(P<0.05). By multivariate analysis, the expression of high molecular weight cytokeratin was unfavorably related with tumor free survival. Conclusion The expression of high molecular weight cytokeratin in breast carcinoma tissues was correlated with biologic malignancies of breast cancer, the negative high molecular weight cytokeratin expression of breast cancer tissues predicts poor prognosis.

Objective To investigate the clinical significance of the expression of lymphocytes and cytokines in patients with laryngeal tuberculosis.Methods 96 cases of laryngeal tuberculosis were selected as the research objects.Of which 42 cases of infiltrating type,31 cases of ulcer type,mass type in 23 cases,the other 50 cases of healthy persons were selected as the healthy control group,all the research objects,extracting the morning fasting venous peripheral blood for detection of T lymphocyte subsets and cytokines were detected,and the results were compared.Results Invasive laryngeal tuberculosis CD3+ index (63.10 ± 5.33) ％ (t =1.922),CD4+ (40.32 ± 5.06) ％ (t =1.758),CD8+ (24.41 ± 4.59) ％ (t =1.710),compared with the control group,CD4+,CD3+ index significantly reduced,CD8+ index increased significantly,the differences had statistical significance (t =1.922,1.758,1.710,all P ＜ 0.05),and the ulcer type and mass type results compared with invasive had significant difference(all P ＜0.05).In the analysis of laryngeal tuberculosis pathological types,reduced the mass type CD3+,CD4+ T index and CD8+ index of lymphocyte increased obviously the most significant;all laryngeal tuberculosis in patients with IL-4,IL-10 and TNF-alpha significantly increased compared with the control group,while the IFN-gamma was significantly reduced,and the mass in the type of change was the most significant,the differences had statistical significance(all P ＜ 0.05).Conclusion The use of lymphocytes and cytokines detection can improve the laryngeal tuberculosis patients with the clinical diagnosis rate,with the detection results of different degree and different pathological types of laryngeal tuberculosis patients,can be used for preliminary assessment of laryngeal tuberculosis disease and pathological type,the choice of treatment modality for patients with guidance value,with in-depth clinical study and promotion application of value.

Objective To understand the clinical features and laboratory examination and diagnosis of Langerhas cell histio-cytosis (LCH) in newborns. Methods Retrospective analysis of the clinical data of a neonatal case of LCH was performed. Results A one-day-old girl was admitted with chief complaint of eating less, less crying and skin rash for one day. The unequal sized rash was on the head, limbs, trunk, toe and oral mucosa. The skin rashes were protruding from the skin and were partially broken and crusted. Biopsy of the skin tissue showed the expression of S-100 and CD1α, consistent with the diagnosis of LCH. Conclusions When new-borns have special rash after birth, LCH should be considered. To avoid misdiagnosis, skin biopsy should be performed.

Objective To screen the serum biomarkers by surface-enhanced laser desorption-ionization time-of-flight mass spectrometry (SELDI-TOF-MS) and establish the decision-tree model for the silica-exposed populations.Methods In addition to 20 healthy people without silica-exposed history chosen as control group,all the subjects diagnosed as different stages (stage 0 group,silica-exposed population,n=20;stage 0+ group, doubtful silicosis,n=20;stage Ⅰ group,stage Ⅰ silicosis) of silicosis according to the national diagnostic criteria (GBZ70-2002) of pneumonoconiosis with no complications were recruited. SELDI-TOF-MS and CM10 chip assay were applied to acquiring serum protein finger printing. The bioinformatic software was adopted to perform data ananlysis and establish Wilks'lambda decision equation and decision tree.Results As compared with that of control group, differential peaks appeared in three groups of silica-exposed population, accounting for 80% of total differential peaks. Wilks'lambda decision equation was established with M/Z 3711.73, M/Z 4183.66, M/Z 5487.28 and M/Z 6124.64, which sensitivity and specificity in differentiating healthy controls and silica-exposed population was 95% and 90% respectively. The sensitivity and specificity of decision tree was 100% and 95% respectively. Neither single peak nor Wilks'lambda decision equation worked well for discrimination of silica-exposed population, while the discriminating rates of decision tree accounted for 100%, 95%, 85% and 90% for healthy control group, stage 0 group, stage 0+ group, stage Ⅰ group respectively.Conclusion M/Z 5933.63,M/Z 4183.66,M/Z 5487.28,M/Z 6124.64,M/Z 5915.14,M/Z 2745.7, M/Z 3711.73, M/Z 2954.78 and M/Z 3401.03 are potential biomarkers for discriminating healthy controls and silica-exposed population, and the decision-tree works well for discrimination of controls, silica-exposed population, doubtful silicosis patients and stage Ⅰ silicosis ones.

Objective To observe the expression of cell proliferation and apoptosis in congenital pulmonary cyst and to investigate their effect in the development of aspergillus.Methods Immunohistochemical method was used to detect the expression of KI-67、BCL-2 and BAX in normal lung tissue from 10 adult(control group 1,CG1),relative normal lung tissue around the aspergillus from 20 aspergillus cases(control group 2,CG2)and abnormal lung tissue from 20 aspergillus cases.Results The expressions of KI-67,BAX and the ratio of BAX/BCL-2 in the bronchial epithelium of aspergillus were significantly higher than those in two control groups(P

Type 1 diabetes is a autoimmune disease that occurs under the influence of both genetic predisposition and environmental factors,mediated mainly by T lymphocytes with various kinds of other involved immune cells.The autoimmune attacks eventually lead to the islet beta cell destruction and insulin insufficiency.Multiple fundamental studies and clinical trials have revealed that umbilical cord blood pluripotent stem cells have the potential to help restore immune balance,induce immune tolerance,stop the autoimmune attacks against beta cells,and promote beta cell regeneration in type 1 diabetes mellitus (T1DM),by means of cell to cell contact and soluble cytokine secretion.For the past few years,the National Clinical Research Center for Metabolic Diseases of Second Xiangya Hospital has been leading the research on stem cell education therapy and has performed the therapy for 35 juvenile type 1 diabetes patients from China and foreign countries,introducing a novel treatment for T1DM.

This report presented a case of 62-year-old woman who was admitted to our hospital for cirrosis, but she had a variety of clinical manifestations,such as abdominal distension,diarrhea,ascites, hepatosplenomegaly,anemia, palpitation, flushing, low blood pressure, arrhythmia and so on. Upper gastrointestinal endoscopy showed thicken mucosa at gastric fundus. Colonoscopy revealed nodular, pseudopolypoid. Ascitic fluid test suggested a transudate. Endoscopic abnormal mucosa biopsy showed chronic inflammation. Many mast cells were seen in bone marrow and liver biopsies,and liver tissue immunophenotype was CD117, and CD68. Thus the patient's diagnosis was systemic mastocytosis. It is rare that a patient only has the gastrointestinal tract symptoms complicated with ascites without skin lesion. The goal for treatment was to reduce hypersecretion of mast cells.

The clinical data of 186 patients with acute gout attack during upper gastrointestinal bleeding were analyzed retrospectively.The ratio of male to female was 1.7∶1, smokers and alcohol drinkers accounted for 66.1% ( 123/186 ) and 62.4% ( 116/186 ) of patients were had underlying diseases.All patients had different degree of joint painful and fever , the blood uric acid levels were higher.Gastroscopic examinations were performed in 166 patients , of whom 88 cases received endoscopic intervention.The symptoms of gout were improved after treatment with dexamethasone and celecoxib ; and the medication did not induce or increase gastrointestinal bleeding.
