OBJECTIVETo observe the effect of moxibustion combined with intermittent urethral catheterization on vesical function in the patient of neurogenic vesical dysfunction.

METHODSSeventy-six cases were randomly divided into an observation group and a control group, 38 cases in each group. The control group was treated with routine intermittent urethral catheterization and the observation group with the intermittent urethral catheterization and moxibustion on Guanyuan (CV 4), Mingmen (GV 4), Zusanli (ST 36), etc. Changes of residual urine volume, white cell count and the balance state of the urinary bladder were selected as the indexes of therapeutic effect and the therapeutic effects were compared between the two groups.

RESULTSThe total effective rate was 97.4% in the observation group and 79.0% in the control group with a significant difference between the two groups (P < 0.05); after treatment, there were significant differences between the two groups in the residual urine volume, the bladder volume and the case numbers reaching to the functional balance state of bladder (all P < 0.05), and there was no significant difference between the two groups in white cell count change (P > 0.05).

CONCLUSIONMoxibustion combined with intermittent urethral catheterization can significantly improve vesical function in the patient of neurogenic vesical dysfunction, reducing residual urine volume, increasing volume of bladder, promoting the balance state of vesical function, but it is basically same as intermittent urethral catheterization in prevention of urinary infection and therapeutic effect.

OBJECTIVETo elucidate the effect of the low dosage endotoxin damage on the expression of the organic cation transporter 1 (OCT1) mRNA in hepatocytes and make an approach to the probable effect of dexamethasone on the expression of the OCT1 mRNA after endotoxin damage.

METHODS(1) The endotoxin damage model was established in rats; (2) The change of the expression of OCT1 mRNA in hepatocytes after endotoxin damage was observed by in situ hybridization method; (3) The change of the ultra structure of hepatocytes after endotoxin damage was observed with the electron microscope; (4) Dexamethasone was injected intraperitoneally before endotoxin damage in order to determine the influence of dexamethasone on the expression of OCT1 mRNA after endotoxin treatment.

RESULTSThe expression of OCT1 mRNA decreased until 16 hours (0.5745+/-0.012, P<0.01) after endotoxin treatment and then increased after this time point, which was still lower than the normal control; The expression of OCT1 mRNA in rat hepatocytes increased at each time point after endotoxin damage with dexamethasone treatment. It was highest at 16 hours (0.6327+/-0.007, P<0.01) after endotoxin damage, but it was still lower than that of the normal control.

CONCLUSIONEndotoxin could repress the expression of OCT1 mRNA even before the low dosage endotoxin inducing serious damage to the structure of hepatocytes; Dexamethasone could not induce the expression of OCT1 mRNA in normal hepatocytes, but could lighten the repression of endotoxin on the expression of OCT1 mRNA. And then the expression of OCT1 mRNA could increase at some extent after endotoxin damage with dexamethasone treatment.

OBJECTIVETo study the clinicopathologic features, immunophenotype and prognosis of primary cutaneous anaplastic large cell lymphoma (CALCL).

METHODSHistopathologic evaluation and immunohistochemical study by Envision method were carried out in 44 archival cases of CALCL. The clinical information and follow-up data were analyzed.

RESULTSThe patients presented with skin nodules, masses or plaques, sometimes associated with ulceration. The commonest sites of involvement were the extremities. Follow-up data were available in 39 patients. The overall survival rate was 87.2% (34/39). Disease relapses were detected in 46.2% (18/39) of the patients. Statistical analysis indicated that patients older than 50 years of age or with no less than two involved anatomic sites were more likely to have disease relapses (P < 0.05). Histologically, 31 cases were classified as common variant, 6 cases as small cell variant and 7 cases as neutrophil/eosinophil-rich variant. Immunohistochemical study showed that the rates of expression of CD30, CD45, CD45RO, CD43, CD3, cytotoxic protein and epithelial membrane antigen were 100% (44/44), 91.2% (31/34), 82.6% (19/23), 94.7% (18/19), 70.0% (28/40), 73.3% (22/30) and 31.8% (7/22), respectively. The CD4(+)/CD8(-), CD4(-)/CD8(+) and CD4(-)/CD8(-) immunophenotypes were found in 58.3% (21/36), 22.2% (8/36) and 19.4% (7/36) of the CALCL cases, respectively. Only one case (3.7%) expressed CD56.

CONCLUSIONSCALCL is a form of low-grade primary cutaneous T-cell lymphoma with a wide spectrum of clinicopathologic pattern. Special variants of CALCL should not be confused with other types of cutaneous lymphomas and inflammatory lesions. CALCL patients older than 50 years of age or with no less than two involved anatomic sites are more likely to have disease relapses.

Polypore fungi is a cluster of important pharmacological fungi with significant antitumor activity. In recent years, the antineoplastic constituents from polypore fungi have been comprehensively studied. Through investigating the domestic and overseas studied paper, the antitumor active constituents derived from polypore fungi including high molecular weight compounds such as polysaccharides, glycopeptides, glycoproteins, lectins, and lipid soluble low molecular weight compounds such as terpenoids, steroids, phenolics, benzopyranones, were reviewed. In addition, the significance in the exploitation of new drug for antitumor by the application of polypore fungi was discussed at the end of this paper.

OBJECTIVETo investigate the clinicopathologic feature, immunophenotype and differential diagnosis of cutaneous Rosai-Dorfman disease (CRDD).

METHODSClinical manifestation, morphologic features and immunohistochemical staining were studied in 8 cases of CRDD.

RESULTSAll 8 patients presented with multiple papules, nodules and/or coalescent patches or plaques distributing over the extremities or trunk, without lymphadenopathy or other systemic abnormalities. Microscopically, the lesions were located intradermally and/or subcutaneously. CRDD was characterized by the presence of S-100 positive histiocytic cells exhibiting emperipolesis, accompanying with infiltration of mixed inflammatory cells. Fibrosis, somewhere in vague storiform pattern due to stromal responses, with distribution of individual neutrophil microabscess was seen in cases with a long course of illness. Dilated vascular spaces in dermis containing numerous large typical histiocytes were seen in 2 cases.

CONCLUSIONSCRDD is a benign, persistent proliferative disease of histiocytes. Systemic involvement is rare, outcome favorable. It should be differentiated from other types of histiocytosis, dermatofibrosarcoma protuberans, xanthoma and lymphoproliferative disorders. Immunohistochemical staining for S-100 protein and CD68 is helpful in making a correct diagnosis.

Abstract?AIM: To investigate mechanism of bradykinin ( BK) on inflammations of retinal pigment epithelium ( RPE) cells.?METHODS: ARPE -19 cells were cultured in vitro, stimulated by 100nM BK for 24h. Cell morphology changes were observed by microscope, and BK receptor localization was detected through cell immunofluorescence. Changes of Ca2+in BK and BR antagonist stimuli were detected by laser scanning confocal microscopy.The expressions of COX-1, COX-2, eNOS and iNOS protein in control group and BK group were detected by Western Blot.?RESULTS: After the stimulation of BK, there was no significant changes of ARPE-19 cells in morphology.Kinin B1 receptors ( B1R ) and B2 receptors ( B2R ) could be detected in ARPE-19 cells.Compared with control group, Ca2+concentrations significantly increased in BK group; in B1R antagonist group and B2R antagonist group Ca2+concentrations increased less than BK group; B1R and B2R antagonist group showed no obvious changes in Ca2+concentrations.Compared with control group, COX-2 and iNOS protein concentrations were significantly increased in BK group (P<0.001).?CONCLUSION:BK induces the increasing expression of COX-2 and iNOS in the cultured ARPE cells through binding with either B1R or B2R.

OBJECTIVETo investigate the effects on chemotherapeutic sensitization of the PI3K inhibitor LY294002 in diffuse large B cell Lymphoma (DLBCL) cell lines ly1, ly8, ly10.

METHODSThe three cell lines were treated with LY294002, or doxorubicin alone or combined or sequentially respectively. Western blotting was used to detect the level of phospho-AKT after the treatment. Flow cytometry combined with annexin V-FITC assay and Brdu incorporation assay were used to analyze the alterations of cell cycle, proliferation, and apoptosis, respectively.

RESULTSLY294002 decreased the level of phospha-AKT efficiently in the three DLBCL cell lines. The ratio of S phase cells was significantly decreased (P < 0.05). Sequential use of LY294002 and doxorubicin increased the ratio of apoptosis and there was significant difference between the sequential group and the other four groups (P < 0.05) at 24, 48, 72(ly1), 48, 72 (ly8) or 24 h (ly10).

CONCLUSIONLY294002 can sensitize doxorubicin-induced apoptosis and may be a potential molecular therapeutic agent targeted at AKT signaling pathway in DLBCL.

OBJECTIVETo evaluate the application of fluorescence in-situ hybridization (FISH) in detection of gene translocation in paraffin-embedded tissue samples of synovial sarcoma.

METHODSInterphase FISH was carried out in paraffin-embedded tissue of 42 cases of synovial sarcoma and 9 cases of non-synovial sarcoma, using a LSI SYT (18q11.2) dual color break-apart probe. In all of the cases studied, the gene fusion product SYT-SSX was also analyzed by reverse transcription-polymerase chain reaction (RT-PCR).

RESULTSPositive signals were detected in 37 cases (88.1%) of synovial sarcoma by FISH, as compared with 35 cases (83.8%) by RT-PCR and 39 cases (92.9%) by both techniques. Of the 39 positive cases, 33 cases (78.5%) revealed SYT gene translocation.

CONCLUSIONSFISH may serve as an adjunctive diagnostic tool in problematic cases of synovial sarcoma and can be applied in paraffin-embedded tissue samples. As compared with RT-PCR, FISH is also sensitive and reliable. The methodology is less labor intensive and time consuming. FISH has great potential in molecular diagnosis of soft tissue tumors.
