The role of neutrophil in the pathogenesis of many diseases attracts more attentions than before. Neutrophil elastase (NE), a powerful neutrol proteinase capable of causing major tissue destruction in many diseases, is mainly present in the azurophil granules of neutrophil. A solid-phase enzyme-linked immunosorbent-biotin assay for human NE has been developed. Only 20?l of plasma sample is needed. Non-smoking healthy adults have 33.7?6.7ng NE/ml plasma; patients with chronic obstructive pulmonary diseases, 48.0+ 10.9 ng NE/ml; patients with pyogenic dermatisis, 69.1?15.7 ng NE/ml; patients with systemic lupus erythematosus, 61.0?13.9 ng NE/ml; patients with aplastic anemia, only 12.3?5.3 ng NE/ml. All of these results have significant differences compared with the result of healthy adults. The results of assay showed that this quantitative assay with good specificity and accuracy may be a better criterion for investigating the effect of NE on pathogenesis of some diseases.

Objective To describe the clinicopathologic features of two cases of mucoepidermoid carcinoma of the skin.Methods Two cases of mucoepidermoid carcinoma of the skin were analyzed histopathologically using hematoxylin and eosin (HE) staining,alcian blue-periodic acid Schiff (AB-PAS) staining and immunohistochemical staining.Relavant literature was reviewed.Results Histopathological examination showed that the tumor was subcutaneously located in both cases,with epidermoid cells and intermediate cells arranged in sheets or nests,as well as different sizes of glandular structures lined by mucinous columnar epithelium in some areas.Both tumors had a relatively clear boundary with peripheral invasive growth and no obvious capsules.Immunohistochemical examination showed positive staining for carcinoembryonic antigen (CEA),high and low molecular weight cytokeratin (CK(H) and CK(L)).The cytoplasm of mucous cells was stained blue with,and mucus was visualized after,AB-PAS staining.Conclusions Primary mucoepidermoid carcinoma of the skin is a kind of malignant tumor arising from skin appendages,whose diagnosis depends on histological and immunohistochemical examination.

Objective To develop an immunohistochemical assay for the diagnosis of cutaneous malignant melanoma (CMM) micrometastasis via blood and lymphatic vessels,and to evaluate its clinical significance.Methods Fifty-three patients (32 males and 21 females) histopathologically diagnosed as CMM were enrolled in this study.The patients were aged (61.2 ± 8.4) years (range,52-72 years).Tissue specimens were obtained from the central area of tumor in each case,and also from removed lymph nodes in some cases.The average duration of follow-up was (65.00 ± 5.68) months.During the follow-up,17 patients died of the recurrence or metastasis of CMM,and 6 patients were lost to follow-up.The expressions of D2-40,S100 and CD34 antigens in 53 tissue specimens were examined by immunohistochemical staining with three individual monoclonal antibodies,or by an immunohistochemical method using 2 two-antibody cocktails (D2-40/S 100 and CD34/S100) and double-color chromogens in single tissue sections.Results Of the 53 patients,30.19％ (16/53) were positive for hematoxylin-eosin (HE) staining combined with immunohistochemical staining with individual monoclonal antibodies,and 49.06％ (26/53) for the immunohistochemical method using two-antibody cocktails and double-color chromogens.Statistical differences were found in the positive rate between the two methods (x2 =3.94,P＜ 0.05).Compared with patients without blood/lymph vessel tumor emboli,those with blood/lymph vessel tumor emboli showed higher lymph node metastasis rate (80.77％ (21/26) vs.37.04％ (10/27),x2 =10.43,P ＜ 0.001),but lower five-year survival rate (42.31％ (11/26) vs.70.37％ (19/27),x2 =4.25,P ＜ 0.05).Conclusions The immunohistochemical method with two-antibody cocktails is superior to HE staining combined with immunohistochemical staining with individual monoclonal antibodies in the detection of blood/lymph vessel tumor emboli.And blood/lymph vessel tumor emboli may be an important prognostic factor in patients with CMM.

A 69-year-old male patient presented with a gradually enlarging mass in the left inner upper thigh for more than 2 months,and pigmented patches in the left medial leg for more than 20 years.Physical examination revealed a painless mass measuring 3 cm × 2 cm × 2 cm in size in the left inner upper thigh.Several pigmented patches were observed in the left medial leg,and the largest pigmented patch measured 2 cm× 2 cm in size with an irregular border and uneven pigmentation.The mass in the left inner upper thigh was resected and subjected to histopathological examination,which showed proliferative epithelioid neoplastic cells with mucous matrix,round and spindle cells of varying sizes separated by mucous matrix.The immunohistochemical study of tumor cells showed positive staining for vimentin,S100 and Melan-A,but negative staining for actin,desmin,CD56,epithelial membrane antigen,cytokeratin,leukocyte common antigen,CD99,chromogranin A and synaptophysin.Hematoxylin-eosin staining of pigmented patches on the left medial leg revealed squamous epithelium covering the surface of lesions with no superficial ulceration or atypia in epithelial cells,unevenly distributed melanophages,fibroplasia accompanied by collagen formation,obviously decreased skin appendages,infiltration of a few inflammatory cells in the dermis.AB-PAS staining was negative.The immunohistochemical study of pigmented patches showed positive staining for vimentin and Melan-A.The patient was pathologically diagnosed with metastatic myxoid melanoma with partial regression of the primary lesion.

BACKGROUND: Several studies have demonstrated that degradable polycaprolactone film has no apparent influences on cellular immune function of rat critical organs including heart, liver, and kidney, and possesses the prerequisite of anti-adhesion formation.OBJECTIVE: To investigate the role of degradable polycaprolactone film in preventing rat peritoneal adhesion following surgery.DESIGN, TIME AND SETTING: The present randomized, controlled animal experiment was performed at the Department of Physiology, Jilin University.MATERIALS: A total of 120 male Wistar rats, weighing 180-220 g, were included in this study. Peritoneal adhesion was induced in all rats. Non-bio-degradable film was sourced from Wuhan Boster Company, China. Polycaprolactone film was purchased from U.C.C Company. England.METHODS: All 120 rats were randomly divided into 3 groups, with 40 rats per group: control, non-bio-degradable film, and polycaprolactone film. Peritoneal adhesion was induced in all rats. The non-bio-degradahle film and polycaprolactone film groups were subjected to peritoneal wound cover with non-bio-degradable film and polycaprolactone film, respectively. From day 1 following surgery, each rat daily received an intraperitoneal injection of 4 mL 2 g/L pseudomonas enzyme, for a total of 3 successive days.MAIN OUTCOME MEASURES: At 1, 3, 7, and 30 days following surgery, 10 rats were selected from each group for observation of peritoneal adhesion.RESULTS: Totally 120 rats were included in the result analysis. Peritoneal adhesion was successfully induced in rats from the control group. From day 7 following surgery, the peritoneal adhesion rate was significantly lower in the polycaprolactone film group than in the control group (P<0.01). In the non-bio-degradable film group, the peritoneal adhesion rate exhibited decreasing followed by increasing tendency; by day 30, the adhesion rate was significantly higher compared to the polycaprolactone film group (P<0.01).CONCLUSION: Polycaprolactone film is degraded by pseudomonas enzyme to avoid the new adhesion caused by foreign stimulation.
