Objective To detect cytokeratin in routine pathology negative regional lymph nodes postoperatively in non-small cell lung carcinoma (NSCLC). To investigate the relationship of lymph node micrometastasis in P-TNM stages NSCLC and survival rates. Methods From Jan. 1996 to Dec. 2003, 107 paraffin-embedded specimens of T1-T4N0-N1M0 NSCLC patients were collected. Anti-cytokeratin(CK) an- tibody AE1/AE3 was applied to detect cytokeratin with Envision~(TM) method in routine pathological negative re- gion lymph nodes in NSCLC, and selected negative control, positive control and blank control. The pulmo- nary hilar lymph node micrometastasis was upward regulated with stage pCK-N1, mediastinal lymph node mi- crometastatsis was upward regulated with stage pCK-N2. The result applied to SPSS11.0 software to process. Results The CK positive rate was 29.9% in all the patients. The CK positive rate was 27% (21/78), 30% (7/23), 67% (4/6)in stage p-Ⅰ, p-Ⅱand p-Ⅲ, respectively. All these data showed the tendency by which detectable rate increased and was accompanied by disease progress. Comparing the annual survival rate and median survival time of the non-micrometastasis group with the mierometastasis group in two groups, the survival rate difference was statistically significant. Comparing the annual survival rate and median sur- vival time in pCK-ⅢA stage with p-Ⅰ-Ⅱstage, pCK-ⅢA stage annual survival rate and median survival time was significantly different (P=0.020). Similarly, comparing the survival rate in pCK-ⅡB stage with p-ⅠB stage, pCK-ⅡB stage survival rate was significantly different(P=0.059). Comparing the survival time of pCK-ⅢA stage with p-Ⅲstage, pCK-ⅡB stage, with p-ⅡB stage, euther survival time difference was statistically significant (P=0.838, 0.518). Conclusions The rate of positive cytokeratin increase is ac- companied by the disease progress in NSCLC. Positive cytokeratin has disadvantagious prognosis. It is showed that pCK-N1 may be equal to p-N1 and pCK-N2 which also may be equal to p-N2. Micrometastasis may affect the UICC staging currently in use.

Urinary tract infection complicated with urinary tract calculi( lithangiuria)is one of the most common diseases causing serious urinary sepsis and septic shock. Recent studies show that the accurate diagnosis,rational use of antibiotics and timely treatment of complications are the key to treatment success. In this article,the latest progress and the treatment strategies for urinary tract infections complicated with lithangiuria are explored.

Chemical constituents of 95% ethanol extract of the dried persistent calyx of Physalis pubescens were investigated. By chromatography on a silica gel column and reverse-phase preparative HPLC, 10 compounds were isolated from the dichloromethane fraction. Based on the MS and 1D/2D NMR data, these compounds were identified as 5-O-(E-feruloyl) blumenol (1), isovanillin (2), (E) -ethyl 3-(4-hydroxyphenyl) acrylate (3), 4-hydroxybenzaldehyde(4), 4-methylphenol (5), (E) -methyl cinnamate (6), 7,3',4' trimethoxyquercetin (7), 5,3', 5'-trihydroxy-3,7,4'-trimethoxyflavone(8), danielone (9), and 5,5'-diisobutoxy-2,2'-bifuran (10).

Gingival fibromatosis is a rare disease, especially its syndromic form. Here, we review the literatures on gingival fibromatosis and briefly summarize some characters on clinical, etiological, genetic and histopathological aspects. We also present a rare case of gingival fibromatosis with multiple unusual findings in a 21-year-old man. And we differentiate it from some well-known syndromes including gingival fibromatosis. Maybe it implies a new syndrome within the spectrum of those including gingival fibromatosis.

Objective To investigate the mechanisms and proliferation inhibitory effects of atractylenolide Ⅰ on SK-OV-3 and OVCAR-3 ovarian cancer cell.Methods SK-OV-3 and OVCAR-3 cells were treated with atractylenolide I with various concentrations at 24 hours,48 hours and 72 hours,and the changes in proliferation were detected by MTT assay.The cell cycles were measured by PI staining and flow cytometry,and the expressions of cyclin D1 and CDK1 were detected by ELISA assay.Western blot was then applied to investigate the effects of atractylenolide Ⅰ on PI3K/AKT signaling pathway in SK-OV-3 and OVCAR-3 cells.Results Atractylenolide I could significantly inhibit the proliferation of SK-OV-3 and OVCAR-3 cells,and its inhibitory effects were concentration and time dependent.In addition,atractylenolide I could also significantly reduce the proportion of cells in S phase and increase the proportion of cells in G2/M phase,and these effects were associated with the down-regulation of CDK1.The results of Western blot indicated that PI3K/AKT signaling pathway was involved in the inhibitory effects of atractylenolide Ⅰ on proliferation and cell cycle.Conclusion Atractylenolide I can down-regulate the expression of CDK1 in ovarian cancer SK-OV-3 and OVCAR-3 cells through PI3K/AKT pathway,which led to cell cycle arrest in G2/M phase,and played an important role in proliferation inhibition of tumor cells.

The effect of glucose on acylcoenzyme A: cholesterol acyltransferase-1 (ACAT-1) expression in THP-1-derived macrophages was investigated.The results showed that high concentrations of glucose up-regulated ACAT-1 expression in THP-1-derived macrophages.

Objective To investigate the effect of chymase on the proliferation of rat cardiac fibroblasts (CFs) and the role of transforming growth factor-?1 (TGF-?_1).Methods Cultured CFs of neonatal SD rats were isolated by trypsinization.Cell number and DNA synthesis were evaluated by MTT assay (A_(490) value) and [~3H]-deoxythy- midine [~3H]-TdR incorporation.The mRNA expression of TGF-?_1 in CFs was determined by RT-PCR.Results Chymase increased CFs numbers and [~3H]-TdR incorporation in a dose-dependent manner.The A_(490) value of CFs stimulated by 15,30 and 60 ng/mL chymase was 0.263?0.033,0.348?0.031 and 0.387?0.026,respectively, which were all significantly higher than that of control (0.201?0.019,P
