Objective To study the pathological characteristics of interleukin-16 (IL-16) and CXC chemokine receptor 3 (CXCR3) in pulmonary artery of smokers with normal lung function and smokers with chronic obstructive pulmonary disease (COPD). Methods We examined surgical specimens from three groups of subjects undergoing lung resection for localized pulmonary lesions: group NS(nonsmokers with normal lung function, n=10); group S (smokers with normal lung function, n=13); group COPD (smokers with stable COPD, n=10). The clinical datas including blood gas analysis, pulmonary function,BMI, smoking index, BODE index, six-minute-walk distance (6MWD), Medical Research Council dyspened scale (MRC), St. George Respiratory Questionnaire (SGRQ) were recorded in all subjects before the operation. We applied technique of hematoxylin-eosin staining to observe pathomorphological changes of the pulmonary arteries. The concentration of IL-16 in lung tissues were measured by ELISA. Muscularized arteries were examined with immunohistochemical methods to identify T-lymphocytes (CD_3), CD_4 T-lymphocytes, CD_8 T-lymphocytes, IL-16, CXCR3. The correlation of IL-16 and CXCR3 in muscnlarized arteries in smokers with stable COPD were analysed. Results (1) The group COPD showed the highest concentration of IL-16 in lung tissue (P <0. 01) . The concentration of IL-16 in group S was higher than group NS (P<0.05). (2) Both in group S and group COPD, the percentage of the muscularized arteries that contained CXCR3 and IL-16 were increased as compared with group NS (P < 0. 01). Moreover there were statistical significance have been observed between group COPD and group S(P < 0.01). (3) The intensity of IL-16 infiltrating the muscularized arteries in group COPD showed a positive correlation with CD_3~+ T-lymphocytes, CD_8~+ T-lymphocytes, CXCR3 (r=0.639,0. 803,0. 696; P < 0. 05 or P < 0. 01), smoking index, BODE index (r= 0.737,0. 704; P < 0. 05). There was inverse relationship between the content of IL-16 in the muscularized arteries in group COPD and forced expiratory volume in one second% predicted (FEV_1 % Pred) and 6MWD (r=-0.803,-0.787; P<0.01). We also found the intensity of CXCR3 infiltrating the muscularized arteries in group COPD showed a positive correlation with CD_3~+ T-lymphocytes,CD_8~+ T-lymphocytes(r=0.650,0.767; P<0.05), smoking index, BODE index (r=0.650,0.767; P< 0.05). There was inverse relationship between the content of CXCR3 in the muscularized arteries in group COPD and FEV_1 % Pred and 6MWD (r=-0.778,-0.774;P<0.01). Conclusions (1) Both in group S and group COPD, IL-16 and CXCR3 were mainly expressed in lymphocytes which were correlated with CD_8~+ T-lymphocytes infiltrating the muscularized arteries. There were some suggestion that IL-16 prohaly recruited CD_8~+ T-lymphocytes into muscularized arteries by enhancing the expression of CXCR3. (2) The intensity of IL-16 and CXCR3 were correlated with the index of clinical and pulmonary function that suggested pulmonary arterial inflammation might be one of the key factors associated with the progression of COPD, and inhibiting the pulmonary artery inflammation played an important role in prevention and cure of COPD.

Objective To evaluate the outcome of super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy (PCNL) and its effect on renal function. Methods From May 2008 to Feb 2010,severe bleeding occurred in 7 patients after PCNL in our hospital.(5 males and 2 females,average age of 54.9 years ).All cases were treated with super-selective renal angiography and 6 cases underwent microcoil embolization. Results Renal angiography showed pseudoaneurysm in 5 cases,pseudoaneurysm with arteriovenous fistula in 1 case and no severe bleeding in 1 case.Successful coil embolization was confirmed in 6 cases by angiography,and bleeding stopped within 3 -7 days after embolization.Serum creatinine and blood urea nitrogen were 59 -98 μmol/L(mean,78.3 μmol/L) and 1.86 -6.92 mmol/L( mean,4.8 mmol/L) 2 weeks after embolization,respectively. Conclusions Super-selective embolization of renal artery for severe hemorrhage after percutaneous nephrolithotomy has the advantages of remarkable hemostatic effects and mild impaired renal function,which is of the first choice.

ObjectiveTo study the pathological characteristics of intra-acinar pulmonary artery inflammation and its correlation with smoking index and disease progression in smokers with normal lung function and smokers with chronic obstructive pulmonary disease (COPD).MethodsPatients requiting lung resection for peripheral lung cancer were divided into group A (nonsmokers with normal lung function,n = 10), group B (smokers with normal lung function, n = 13), and group C (smokers with stable COPD,n = 10).The lung tissue far away from rumor were resected to compare the pathological changes of intraacinar pulmonary arteries and infiltration level of inflammatory cell in pulmonary non-muscularized arteries (NMA), pulmonary partially muscularized arteries (PMA) and muscularized arteries (MA) among the three groups.The correlation analysis was made among infiltration level, smoking index, percentage of predicted value of forced expiratory volume in one second (FEV,％ Pred), six-minute-walk distance (6MWD) and BODE index.Results (1) Both group B and group C showed the intima and media thickness of MA was significantly higher, the lumen area of MA was narrower and the proportion of MA was higher, and collagenous fiber of MA adventitial proliferated and area increased in group C(P ＜0.05 or P ＜0.01).(2) In group B and group C, the percentage of the intra-acinar pulmonary arteries that contained leukocytes, T lymphocytes, CD8+ T lymphocytes and the number of these positive cells infiltrating the intraacinar pulmonary arteries were increased, especially an increased number of CD8+ T lymphocytes infiltrating in the arterial adventitia as compared with group A, moreover there were significant difference between group C and group B (P ＜ 0.05 or P ＜ 0.01).In group B and group C, the degree of these positive cellsinfiltrating NMA, PMA and MA presented a decreasing sequence (P ＜ 0.05 or P ＜ 0.01).Among the intima, media and adventitia of MA, the infiltration of these positive cells was the highest in the adventitia.Among group A, group B and group C, infiltration degree of CD4+ T lymphocyte, B lymphocyte, macrophage and neutrophil demonstrated no significant difference, also among NMA, PMA and MA (P ＞ 0.05).(3)The number of leukocytes, T lymphocytes, CD8+T lymphocytes infiltrating MA showed a positive correlation with the thickness of MA (r =0.563,0.627,0.589 ,P ＜0.01 ,respectively) and smoking index (r =0.551,0.665, 0.600, P ＜ 0.01, respectively), moreover the degree of these cells infiltrating MA demonstrated negative correlation with FEV1 ％ Pred (r = - 0.763, - 0.703, - 0.767, P ＜ 0.01, respectively).Also infiltrating degree of T lymphocytes and CD8+ T lymphocytes was positively correlated with BODE(r = 0.390,0.476,P ＜ 0.05, respectively). Furthermore the infiltrating degree of CD8+ T lymphocytes had negative correlation with 6MWD (r = - 0.356, P ＜ 0.05).Conclusions(1) Pulmonary arterial inflammation appears in smokers with normal lung function and smokers with COPD patients.It involves in all types of intra-acinar pulmonary arteries especially NMA and infiltrates whole layer of MA with a characteristic of CDs+T lymphocytes infiltrating in the adventitia of intra-acinar pulmonary arteries. (2)Pulmonary inflammation is closely correlated to cigarette smoking and clinical parameters such as BODE index, FEV1％pred and 6MWD.It is one of the key factors affecting the progression of COPD.
