OBJECTIVE: To detect the expressions of chemokines interleukin-8 (IL-8), monocyte chemoattractant protein-1 (MCP-1), and macrophage inflammatory protein-1 (MIP-1) mRNA in non-small cell lung cancer (NSCLC) tissues, to analyze their relationship with microvessel counts (MVC), and their significance in clinic pathologic features of NSCLC. METHODS: In situ hybridization was used to measure the expressions of chemokine IL-8, MCP-1, and MIP-1 mRNA in 40 NSCLC tissues and 10 normal pulmonary tissues, and immunohistochemical staining was carried out to measure the MVC in the above tissues. RESULTS: The positive ratios of IL-8, MCP-1, and MIP-1 mRNA in the 40 NSCLC tissues were apparently higher than those in the 10 normal contrast tissues and the difference was statistically significant. The numbers varied accordingly with the different clinic pathologic features of NSCLC, showing that Group T(3) > Group T(2) or Group T(1), Group III stage> Group II stage> Group I stage Group lymph node and remote transferred > Group non-transferred, and Group of survival time no more than 3 years > Group of survival time more than 3 years. The positive expressions among IL-8, MCP-1,and MIP-1 mRNA and between these and the MVC all had mutually positive correlation. CONCLUSION Chemokine IL-8, MIP-1, and MIP-1 in NSCLC tissues might cooperate with one another to promote the tumor angiogenesis and affect the progression, metastasis and prognosis of the tumor.

OBJECTIVE: To detect tumor microvessel count (MVC), tumor associated macrophage (TAM) and Mast cell (MC) counts, and to explore their correlation and the clinical significance in non-small cell lung cancer (NSCLC). METHODS: Immunohistochemical staining (ABC method) was used to measure MVC and TAM and MC counts in 40 cases of NSCLC tissues and 10 cases of normal pulmonary tissues as contrast. RESULTS: The counts of microvessel, TAMs, and MCs in the NSCLC tissues were apparently higher than those of the normal tissues, and these counts increased with the development of T stage and clinical stage, metastasis of the tumor, and the reduction of the patient survival time. The positive correlation was showed among the counts of microvessel, TAMs, and MCs. CONCLUSION Tumor interstitial infiltrating inflammatory cells, TAMs and MCs can cooperatively promote the tumor angiogenesis,which associates with the development, invasion, metastasis and prognosis of NSCLC.

OBJECTIVETo explore the mechanism of 'erythroblast island (EI)' formation in the bone marrow of patients with immun-related hemocytopenia (IRP).

METHODSThe category of BM-auto antibody (au Ab) in 48 patients with IRP was detected with FCM. The BM-au Ab in the 'EI' of these cases were explored with immuonhistofluorescence (IF). Clinical and laboratory characteristics of these cases were also analyzed retrospectively.

RESULTSIgG could be detected in the 'EI' on the BM smear of 14 cases (29.17%), BM-au Ab mainly deposited at the edge/membranes between macrophage and erythroblasts rather than cyto plasm. Positive reaction were seen in all the cases with GlycoAIgG. The red blood cell count [(1.8 ± 0.5) × 10(12)/L] and hemoglobin level [(59.6 ± 16.2)g/L] were significantly lower than that in the IF(-) group [(2.5 ± 0.9) × 10(12)/L and (83.4 ± 25.0) g/L] (P < 0.05). The percentage of reticulocyte [(2.0 ± 0.8)%], serum level of IBIL [(9.4 ± 4.7) µmol/L], percentage of erythroblats in sternum BM (0.441 ± 0.139) and response rate to therapy (85.7%) in IF(+) group were significantly higher than that in IF(-)group [(1.3 ± 1.0)%, (6.6 ± 6.7)µmol/L, 0.298 ± 0.082, 61.3%, respectively] (P < 0.05).

CONCLUSIONMacrophage was connected with erythroblasts through autologous IgG in the 'EI's of some patients with IRP. 'EI' were the places where macrophages devoured and destroyed erythroblasts rather than erythroid development and differentiation. The pathogenetic mechanism of IRP might be associated with macrophages phagocytosing and destroying BM hematopoietic cells.

OBJECTIVETo explore factors affecting occupational adaptability in nurses for offering basis to increase their occupational adaptability.

METHODSFive hundred and forty-five nurses were investigated with work ability index questionnaire and occupational stress instruments.

RESULTSThere were many risk factors affecting occupational adaptability in nurses. The main variables that influenced occupational adaptability included work-overtime, mental load, social support, physical environment, and job hazards. The social support was the factor increasing the occupational adaptability of the nurses (P < 0.01, OR = 0.912). Five factors including work overtime, mental load, social support, physical environment and job hazards were introduced in the Logistic equation. The established functions were: Logit (P) = -11.357 + 1.011x(1) + 0.335x(2) - 0.076x(3) + 0.260x(4) + 0.129x(5).

CONCLUSIONThere are many risk factors affecting occupational adaptability in nurses. Relevant measures should be taken to promote the occupational adaptability in nurses to reduce the risk factors.

OBJECTIVETo investigate the infection rate and subtypes of human papilloma virus(HPV) in patients with oropharyngeal squamous cell carcinoma (OSCC) and analyze the clinicopathologic features of patients with or without HPV infection.

METHODSA total of 66 biopsy or surgical specimens of OSCC archived in the Pathology Department of Chinese Academy of Medical Sciences were analyzed by polymerase chain reaction (PCR), and the generic amplification products were detected by DNA enzyme immunoassay (DEIA) and typed by reverse hybridization line probe assay.

RESULTSHPV-DNA was detected in 11 (16.7%) of all specimens. Among them, 7 were infected with HPV-16,and the remaining 4 patients were infected with HPV-16/11, HPV-35, HPV-58/52, and HPV-33/52/54, respectively. HPV-16 was detected in 72.7% of all positive specimens. There were more females in HPV-positive group than HPV-negative group (36.4% vs. 1.8%,P=0.002). Patients with HPV-positive tumors were more likely to be non-smokers (36.4% vs. 0,p=0.001) and non-drinkers (45.5% vs. 1.8%,p=0.001) than those with HPV-negative tumors. The proportion of moderately or poorly differentiated tumors was higher in HPV-positive patients than HPV-negative patients (81.8% vs. 63.7%), although without statistical significance (p=0.409). No difference was observed in T classification, N classification, and overall tumor stage.

CONCLUSIONSHPV infection rate was 16.7% in this cohort. HPV-positive OSCC has its unique etiologic and clinicopathological characteristics.
