The expression of proliferating cell nuclear antigen (PCNA) was studied in 50 cases of squamous cell carcinoma of the skin using immunohistochemistry and PCNA cyclin monoclonal antibody. PCNA staining was found in the nuclei of tumour cells, two types of staining were seen, a granular pattern and a more diffuse nuclear staining. The expression of PCNA showed a significant positive correlation with degrees of differentiation of the carcinoma cells and lymph node metastasis (P

The expressions of p53 protein, PCNA and macrophage count in 50 cases of skin squamous cell carcinoma were studied by LSAB immunostaining of monoclonal antibodies (PC-10, CD68 and Do-7). The relationship between the proliferation of cancer cell and the count of stroma macrophage to the degree of differentiation was studied and observed in situ. The results showed that the positive rates of expression of both p53 protein and PCNA in the squamous cell carcinoma were 56% and 100%, respectively. The distribution and strength of the expression of p53 protein and PCNA were positively correlated to the degree of cell differentiation. Macrophoge regularly located in the margin of cancer nest. The macrophage count was reversely correlated to the degree of differentiation. It is concluded that the degree of differentiation is parallel to the expression of p53 protein and PCNA, whereas, the macrophages in the stroma to some extent inhibits the cancer cell proliferation.

Objective To investigate the chemosensitivity of ovarian cancer SKOV3ip1 multicellular aggregates to cisplatin and taxol and to explore the possible mechanisms accounting for the effect Methods Liquid overlay system was employed to obtain multicellular aggregates (MCA) We detected the resistance with trypan blue exclusion testing, clonogenic assay, cell cycle profiles and apoptosis with flow cytometry Results MCA cells showed higher cell viability than monolayer cells ( P =0 045 and P =0 003, respectively). After 40 ?mol/L cisplatin exposure for 12 hours, no clone (≥50 cells) was formed After 10 ?mol/L taxol exposure for 12 hours, the clone formation showed significant difference in 100 cell group between multicellular aggregates and monolayer cells ( P

Objective To investigate the concentration changes of vascular endothelial growth factor(VEGF), nitric oxide(NO) and endothelin (ET) in elderly patients with obstructive sleep apnea syndrome (OSAS) combined with eerebrovascular disease.Methods One hundred and thirty-two subjects were divided into four groups: OSAS with cerebrovaseular disease group (OC group), OSAS without cerebrovascular disease group (O group), cerebrovascular disease without OSAS group (C group) and normal control group (N group).The concentrations of VEGF, NO and ET in the plasma were compared in each subgroup.Results The concentration of VEGF was significantly increased in OC group and O group compared with C group and N group[(195.34±56.7)ng/L, (162.34±48.7)ng/L, (156.4 4±51.8) ng/L, (114.1 ± 54.2) ng/L, F= 21.02, P< 0.05].The concentration of NO was increased gradually in OC group, C group, O group and N group[(62.3±4.9)mmol/L,(64.7±5.1) mmol/L, (66.2± 4.2)retool/L, (77.5 ± 6.8) mmol/L, F= 17.35, P<0.05], and the concentration of ET was decreased gradually in OC group, C group, O group and N group[(59.8±9.6)ng/L, (56.5±4.3)ng/L, (54.7±7.9)ng/L, (37.2±8.5)ng/L, F= 4.27, P<0.05].Conclusions The concentrations of VEGF and ET are increased and the concentration of NO is decreased in patients with OSAS.Patients with OSAS combined with cerebrovascular disease have higher VEGF and ET concentrations and lower NO concentration than in patients with simple OSAS.The results indicate that vascular endothelial dysfunction may play an important role in the development of cerebrovascular disease in patients with OSAS.

Objective To evaluate the effect of montelukast combined with seretide in treatment of patients with asthma and its influence on balance between Th17 and Treg cells, and expression of IL-4 and IFN-γ.Methods 110 patients with asthma were randomly divided into observation group and control group, observation group of 55 cases, using montelukast combined with seretide, control group of 55 cases, using seretide,compared two groups of patients with pulmonary function changes, peripheral inflammatory factor changes and influence on Th17 and Treg cells balance.

Objective To explore the clinical experience of liver retransplantation in management of biliary complications after liver transplantation.Methods The clinical data of patients receiving liver transplantion in our department between April 2002 and Aug. 2004 were retrospectively analyzed, including 5 patients being subjected to liver retransplantation because of serious biliary complication.Results Three patients were cured with the survival time being 5 months, 6 months and 8 months respectively. Two patients died at 8th and 43rd day: one died of liver non-function combining with lung infection and heart failure, and another died of renal failure. Complications included liver absess, biliary infection, wound infection, hydrops abdominis and lung infection.Conclusions Liver retransplantation is an effective treatment for serious biliary complications after liver transplantation. Surgical procedure, indication, operative opportunity, perioperative monitoring and so on contribute to the increase of the survival rate of the patients receiving liver retransplantation.

Objective To investigate the expression of matrix metalloproteinases(MMP) related to oncogene C-myc and tumor differentiation of cutaneous squamous cell carcinoma (CSCC). Methods Expression of MMP2,MMP9 and C-myc was detected by immunohistochemistry in 68 paraffin embedded specimens of CSCC. Results Distribution of MMP2 and MMP9 was demonstrated within cytoplasm of tumor and stromal cells, especially for those cells at the interface of tumor and interstitial tissues. No expression of MMP2 and MMP9 was observed in the horny centers of tumor cell nests. Expression of MMP2 and MMP9 increased along with the decreasing of the differentiation of tumor tissue and the increasing of C-myc expression. Conclusions Expression of MMP2 and MMP9 might be a common event for both tumor and stromal cells but parenchymal tumor cells might predominate over the activation of MMP2 and MMP9. Oncogene C-myc protein might promote the secretion of MMP2 and MMP9 by tumor cells.
