To investigate the relationship of between p21wAF1 and PCNA expression and the patients' prognosis in breast carcinoma. MethodExpression of p21wAF1 and PCNA was determined by S-P immunohistochemical technique in 152 patients with breast carcinoma. ResultsPositive immunostaining of p21WAf1was detected in 61(40.1% ) primary breast carcinoma, in which 43(70.5% ) were low expression, and 18(29.5% ) over expression of 152 PCNA positive cases, 69(45% ) expressed with low index and 83(55% )expressed with high index. p21wAf1 expression level was correlated with tubule formation (γs= 0.341, P<0.01 ),nuclear atypia(γs=0.516, P<0.01), mitosis(γs=0.351, P<0.01)and histological grade(γs=0.415, P<0.01)in breast cancer tissue. Univariate analysis demonstrated less disease-free survival in patients with higher p21WAF1 (x2 = 6.92, P< 0.01 ) and PCNA (x2 = 5.14, P<0.05)expression than in those with lower expression. The survival term of the patients with p21WAF1 -/PCNA low index, p21wAF1 +/PCNA low index, p21WAF1 +/PCNA high index and p21WAF1 -/PCNA high index groups was successively shortened. Conclusions( 1 ) Combined detection of p21wAF1/PCNA is helpful to judge the proliferating activity of the tumor cells and the patients prognosis. (2) Different expression level of p21WAF1in breast carcinoma is probably related the different regulating directions.

Objective To detect the expression of human epithelial growth factor receptor 2 (HER-2) in advanced lung adenocarcinoma with epithelial growth factor receptor (EGFR) mutation, and to explore the potential of HER-2 as a therapeutic target for drug resistance in patients with EGFR mutations. Methods HER-2 is commonly expressed in the advanced lung adenocarcinoma with EGFR mutations, mainly in the cell membrane. Results The overexpression rate of HER-2 protein in tissues of advanced lung adenocarcinoma with EGFR mutations was 33.3%(28/84). The overexpression rate of HER-2 protein in patients>50 years of age was 40.3%(27/67), which was significantly higher than that of patients ≤50 years of age [5.9 % (1/17)], the difference was statistically significant (χ2=7.227, P=0.007). The overexpression rate of HER-2 protein in patients with high pathological differentiation [44.4 % (8/18)] was higher than that in patients with poor pathological differentiation [30.3%(20/66)], but the difference was not statistically significant (χ2=1.273, P=0.259). The overexpression of HER-2 protein in patients with EGFR 21 exon mutation [40.5 % (17/42)] was significantly higher than that of EGFR19 exon mutation [25.0%(10/40)], but the difference was not statistical significance (χ2=2.222, P=0.136). Conclusions The overexpression rate of HER-2 protein in advanced lung adenocarcinoma patients with EGFR mutation is high, which is related to the age and tumor differentiation. HER-2 is expected to be a potential therapeutic target for drug resistance patients with EGFR mutations.

Objective:To investigate the clinical characteristics and prognosis of cryptococcal meningitis patients with anti-granulocyte-macrophage colony-stimulating factor (GM-CSF) autoantibodies.Methods:A total of 216 non-acquired immunodeficiency syndrome (AIDS) related cryptococcal meningitis cases with positive cultures of Cryptococcus, hospitalized at Huashan Hospital, Fudan University during January 2014 and December 2021, were retrospectively included. The serum anti-GM-CSF autoantibodies were detected by enzyme linked immunosorbent assay, and the clinical characteristics and prognosis were compared between patients with and without anti-GM-CSF autoantibodies. Statistical comparisons were mainly performed using the chi-square test or Fisher′s exact test. Cox proportional-hazards model was used to analyze the risk factors associated with prognosis. Results:Among 216 enrolled patients, 23 patients were positive of anti-GM-CSF autoantibodies, with a positive rate of 10.6%. Among 23 patients, seven cases were infected with Cryptococcus gattii, and 16 cases were infected with Cryptococcus neoformans. In the group with positive anti-GM-CSF autoantibodies, 30.4%(7/23) of the patients were infected with Cryptococcus gattii, which was higher than that of 1.6%(3/193) in the group with negative anti-GM-CSF autoantibodies, and the difference was statistically significant ( χ2=38.82, P<0.001). In the group with positive anti-GM-CSF autoantibodies, 30.0% (6/20) had mass lesions with a diameter greater than three centimeters in the lungs, and the one-year all-cause mortality rate was 50.0% (10/20), which were both higher than those of 3.4%(5/145) and 16.1% (29/180) in the negative group, respectively. The differences were both statistically significant (both Fisher′s exact test, P<0.01). Age≥60 years (hazard ratio ( HR)=4.146, P=0.002), predisposing factors ( HR=3.160, P=0.021), epilepsy ( HR=6.129, P=0.002), positive anti-GM-CSF autoantibodies ( HR=2.675, P=0.034), white blood cell count of cerebrospinal fluid (CSF)<100 ×10 6/L ( HR=2.736, P=0.039), the titers of cryptococcal capsular polysaccharide antigen of CSF≥1∶1 280 ( HR=4.361, P=0.009) were independent risk factors for one-year all-cause mortality in patients with cryptococcal meningitis. Conclusions:In non-AIDS related cryptococcal meningitis patients, the positive rate of serum anti-GM-CSF autoantibodies is as high as 10.6%. Patients with anti-GM-CSF autoantibodies could be infected with both Cryptococcus neoformans and Cryptococcus gattii, and they have higher proportion of lung mass lesions than patients with negative anti-GM-CSF autoantibodies. The one-year survival rate decreases significantly in patients with anti-GM-CSF autoantibodies, which is an independent risk factor for the prognosis of cryptococcal meningitis.

OBJECTIVE: To study the anti-inflammatory effect and its mechanism of the extract of Dcsmodium microphyllum, so as to provide experiment reference for further study of D. microphyllum. METHODS: Acute inflammatory model was established by xylene,glacial acetic acid and carrageenan. Using dexamethasone as positive control (0.005 g/kg), inhibitory effects of intragastric different doses of the extract of D. microphyllum (50, 30, 15 g/kg) on xylene-induced ear swelling in normal mice and adrenalectomized mice, glacial acetic acid-induced permeability increasing of abdominal capillaries in normal mice, carrageenan- induced paw swelling in normal mice and adrenalectomized mice were investigated. The levels of MDA, SOD and NO in the inflammatory tissue of toes of adrenalectomized mice were detected in carrageenan-induced inflammation model. Blank group was set for control (ig. equal volumn of water). RESULTS: Compared with blank group, ear swelling degree of normal mice and adrenalectomized mice were decreased significantly in D. microphyllum extract high-dose and medium-dose groups while inhibitory rate of ear swelling was increased significantly; the permeability of abdominal capillaries of normal mice was significantly decreased in D. microphyllum extract groups; the swelling degree of toes in normal mice of D. microphyllum extract high-dose and middle-dose groups and adrenalectomized mice were significantly decreased while inhibitory rate of toe swelling was increased significantly (P<0.05 or P<0.01). The levels of MDA and NO in the toe inflammatory site of adrenalectomized mice were decreased significantly in D. microphyllum extract high-dose and medium-dose groups, while the level of SOD was increased significantly (P<0.05). CONCLUSIONS: D. microphyllum extract can inhibit acute inflammation in mice significantly. Its anti-inflammatory mechanism is associated with decreasing MDA and NO while increasing SOD levels, and the anti-inflammatory effect does not depend on the hypothalamus-pituitary-adrenal axis system.
