Objective To explore the changes of the levels of IL-8,LTB4 and its function in invasion in patients with chronic obstructive pulmonary disease(COPD).Methods The concentrations of IL-8 and LTB4 in serum and sputum were determined with enzyme linked immunosorbent assay(ELISA)in 30 cases of patients with COPD in acute aggravating stage and paracmasis and in 20 cases healthy adults.Blood routines were detected in all obstructs.Results The concentrations of IL-8 in serum and sputum in acute aggravating stage were(181.41±18.49)ng/L and(74.03±20.64)ng/L,significantly higher than those in paracmasis and the reference group(152.33±17.48)ng/L and(42.30±14.99)ng/L,P＜0.05).The concentrations of IL-8 in serum and sputum in paracmasis were significantly higher than those in reference group[(52.75±13.79)pg/ml and(17.15±5.36)ng/L,P＜0.05].The concentrations of LTB4 in sputum in acute aggravating stage were(2300.91±496.01)ng/L,significantly higher than those in paracmasis and the reference group[(1884.14±651.37)ng/L,P＜0.05].LTB4 level in acute aggravating is not significantly different from those in paracmasis and the reference group[(1941.30±301.62)ng/L and(1880.77±302.11)ng/L,P＞0.05).Conclusion Both IL-8 and LTB4 play important roles in the coupe of inflammatory reaction of air passage of COPD.

Objective : To analyze the clinical characteristics of patients with adenomyosis (AM) and endometrial cancer (EC) and their role in preoperative diagnosis. Methods : A total of 142 patients with AM complicated with EC or endometrial atypical hyperplasia (EAH) and AM with abnormal uterine bleeding ( AUB) during the same period were collected from this hospital. They were divided into AM with EC or EAH group (71 cases) and control group (71 cases) according to whether they were complicated with EC or EAH. The clinical data of the patients were retrospectively analyzed , and the clinical characteristics and treatment strategies of the patients with adenomyosis complicated with endometrial cancer were discussed. Results : Univariate analysis showed that age , increased proportion of CA125 and CA125 , uterine volume , proportion of hypertension and abnormal endometrial ultrasonography in patients with AM with EC or EAH were significantly higher than those in the control group , and the proportion of dysmenorrhea was significantly lower than that in the control group , and the difference was statistically significant (P < 0. 05) . Multivariate Logistic regression analysis showed that endometrial thickening , endometrial echogenicity , and endometrial thickening combined with echogenicity were independent risk factors for AM with EC or EAH. Conclusion In clinical practice , the patients with AM with endometrial thickening or uneven echo - echo of ultrasound should be treated by hysteroscopy and curettage before further operation plan is formulated , so as to achieve the purpose of early diagnosis and treatment of EC.

Objective To explore the clinical significance of lymph node micrometastases in stage Ⅱ rectal cancer patients. Methods Forty-two patients with rectal cancer underwent total mesorectal exci-sion between January 2000 and August 2001 were included, 484 lymph nodes were studied in paraffin blocks that had previously been considered free by conventional histopathological examination. These lymph nodes were submitted to immunohistochemical analysis using cytokeratin 20 (CK20) monoclonal antibodies to identify micrometastases. Five-year follow-up information was obtained on these patients. Observed survival rates and assessed respectively in the patients with and without micrometastases. Results Micrometastases were detected in 33 lymph nodes (6.8% ,33/484) of 15 cases (35.7%, 15/42). The five-year survival rate was 40.0% in the patients with micrometastases, whereas in the patients without micrometastases, the survival rate was 92.6%(P = 0.000,by the Log-rank test). By multivariate Cox regression analysis, lymph node mi-cromctastases was closely correlated with post-operative recurrence or metastases, the value of RR was 11.435. Conclusions Detection of micrometastases is an important prognostic tool in stage Ⅱ rectal can-cer. In this study, lymph nodes micrometastases is an independent prognostic factor for overall survival. These patients maybe get benefit from adjuvant chemotherapy.

BACKGROUND: Coronary artery disease (CAD) risk in type Ⅱ diabetics is one of the hot topics in clinical research.OBJECTIVE: By using electron-beam tomography(EBT) technology, heart scans were performed to investigate coronary artery lesion in type Ⅱ diabetics and their CAD risks were evaluated as well.DESIGN: Comparative study based on type Ⅱ diabetics complicated with coronary artery lesion.SETTING: Gerontology department in a hospital affiliated to a military medical university of Chinese PLA.PARTICIPANTS: From January 2002 to June 2004, 93 inpatients between the ages of 36 and 78 in the Gerontology Department of Xijing Hospital, an affiliation to the Fourth Military Medical University of Chinese PLA, were selected(male 80, female 13) . Totally 25 of all the patients proved normal by physical examinations were set as normal control(male 22, female 3) group; other inpatients were divided into the abnormal blood glucose group and the coronary heart disease (CHD) group respectively according to their examination results. Of the 57 patients in the abnormal blood glucose group,49 were male and 8 were female. This group was divided into two subgroups:the impaired glucose tolerance group(IGT) containing 29 patients and the diabetes group containing 28 patients. In this group, 44 patients have had heart symptom of different extent. Of the 11 patients in the CHD group, 9 were male and 2 were female. Inclusion criteria: patients with type Ⅱ diabetes were defined by American Diabetes Association in 1979; patients with CHD were defined in the report of the Joint International Society and Federation of Cardiology/World Health Organization Task Force on the standardization of clinical nomenclature and criteria for diagnosis of ischemic heart disease in 1979, and they were all confirmed by coronary angiography. Exclusion criteeases.METHODS: Both plain EBT heart scanning and contrast-enhanced heart scanning were performed on the 93 patients to evaluate the occurrence of coronary artery calcification(CAC), the number of stenosed coronary arterie,and the number of soft plaques. Additionally, other examination results including blood glucose, blood HbA1c and blood lipid were also collected for comparison between the conditions of coronary artery and assessment of the CHD risk among groups.MAIN OUTCOME MEASUREMENTS: In all the groups, the occurrence of CAC, the number of stenosed coronary arteries and the number of plaques were compared, and the CHD risk was analyzed.RESULTS: The occurrence of coronary artery calcification was significantly increased in all the study groups as compared with the control group(x2 = 18.88, P < 0. 01 ). Increasing trend was also observed in the study groups when calculating the number of branches with coronary stenosis and plaques ( F = 10. 758, P < 0. 01; F = 9. 991, P < 0.01 ). CHD risk in diabetes was estimated to be 7. 514 (95% confidence interval, 1. 885 -63. 778).CONCLUSION: Coronary artery lesion can be easily observed in type Ⅱ diabetics,and high CHD risk is predicted in this population. Early diagnosis of CAD and early rehabilitation intervention in grade 2 are extremely important in improving the quality of life and reducing the disability ratio of type Ⅱ diabetics.Huang C, Gao JY, Wong XM, Li R, Yang AL, Zheng MW, Xue FB. Risk analysis of coronary artery disease in type Ⅱ diabetics.

Objective To evaluate the echocardiographic features of coronary artery dilation (CAD) and coronary artery aneurysms (CAA) in Kawasaki disease dynamically.Methods Echocardiography was performed in KD cases for measurement of the diameter of the coronary artery.Results Twelve CAD and four CAA were identified in forty-one patients.In CAD group,left coronary artery (LCA) is more susceptive to dilation than right coronary artery (RCA)(P<0.05).Both LCA and RCA were involved in CAA group,the maximum diameter of coronary artery is 10mm.Six to eighteen days after treatment,LCA were regressed significantly in CAD group(P<0.05),but the diameter of RCA in CAD group and coronary artery in CAA patients have no change(P>0.05).Ten coronary artery lesion patients were followed up,8 CAD cases regressed completely,1 CAA extended,the other CAA regressed completely.Conclusions In CAD group,LCA is more susceptive to dilation than RCA,but it regressed significantly in a short time after treatment.Echocardiography is a non-traumatic method to detect the coronary artery lesions in KD patients dynamically.
