Objective To investigate the expressions of CCL25 and CCR9 in pancreatic cancer and tumor draining lymph nodes (TDLNs) , and to find out the relationship between the expressions of CCL25/CCR9 and the prognosis of pancreatic cancer. Methods 58 patients with pancreatic cancer and 10 patients with pancreatic benign diseases who received resectional surgery were studied from Jan 2006 to Jan 2008. Immunohistochemistry was used to detect the expressions of CCL25 and CCR9 in pancreatic cancer,TDLNs and benign diseases. Result Immunohistochemistry showed that the positive rate of CCR9 in TDLNs (86. 2%) was higher than in pancreatic cancer (79. 3%) (P<0. 05),which in turn was higher than benign diseases (40%) (P<0. 05). The positive rates of CCL25 in TDLNs, pancreatic cancer and benign diseases were 91.4% (53/58), 62.1% (36/58) , 40% (4/10),respectively. The expressions of CCL25/CCR9 protein in pancreatic cancer was associated with the clinical stage and the pathological type. There was significant difference in the survival time between the CCL25/CCR9 positive and negative patients (P<0. 05). Conclusions The expressions of CCL25/CCR9 were increased in pancreatic cancer and TDLNs, which suggested that CCL25/CCR9 might be involved in pancreatic cancer metastasis. CCL25/CCR9 might be regarded as an important marker in the prognosis.

Fascin,an actin cross-linking protein found in membrane ruffles,microspikes,and stress fibers,induces membrane protrusions and increase cell motility in various transformed cells.The expression of fascin in epithelial neoplasms has only been described recently,and fascin overexpression may play an important role in the progress of neoplasms.This article reviews the current situation and the up to date progress of study concerning fascin and epithelial neoplasms.

Bladder pain syndrome (BPS) is a chronic disease characterized by urinary symptoms and pain in or around the bladder with uncertain reasons. The incidence of BPS is higher in the female and people in American and Europen countries. The BPS patients' quality of life has been damaged and a new disabled group has been formed. The pathogeneses of BPS include pathogens inducing inflammation, chronic ischemia and ischemia-reperfusion injury producing degeneration in bladder, lower urinary epithelium dysfunction, apoptosis in bladder tissue, epigenetic reprogramming, abnormal intracellular signaling pathway, pain regulating dysfunctioning, and autophagy inhibit-ed. There is no identified diagnosis for BPS. Cystoscopy, urodynamia, and biomarks in blood or urine are helpful in diagnosis. Diet, psycho-logical intervention, oral medicine, intravesical therapy, nerve blocking and nerve stimulation, and surgeries have been used for it, but the ef-ficacy remains unsatisfied.

Objective This study aims to observe and analyze the result of implementing health management and intervention for chronic Keshan disease treatment. Methods Certain amounts of chronic Keshan disease patients in Keshan disease area were chosen and given health management and treatment intervention including primarily pharmacological treatment for the chronic congestive heart failure together with health education and life style instruction. From 2006 to 2008, three interventions were conducted every six month. Electrocardiogram description, proportion of heart to chest, classification of heart function, types of Keshan disease and labour capacity at the initial and the last stage of the intervention were taken as judging indexes. If one of the indexes was improved then the intervention will be regarded as effective. The number of effective cases and effective rate were counted in order to observe the impact of intervention times and different medicine on intervention results. Results Altogether 345 Keshan disease patients were involved in the study, among them 207 were effective, the effective rate was 60%(207/345). One hundred and eighty were involved in the intervention for once, and the effective rate was 44%(79/180). Ninty-one took part in the intervention twice, and the effective rate was 66%(60/91). Seventyfour attended the intervention for three times, and the effective rate was 92% (68/74). There were significant difference among groups of different intervention times (χ2 = 52.16, P < 0.01), and the effective rate increased with increased intervention times. Three times were higher than that of one or two times (χ2= 15.81, 49.56, all P< 0.0125). Twice were better than once(χ2 = 11.76, P < 0.0125). There were significant difference among groups of different medicine groups(χ2 = 19.56, P< 0.01). Among different medicine groups, the efficacy of angiotensin converting enzyme inhibitor(ACEI) group was the highest 77%(82/106) while the cardiotonic medicine group was 50%(47/94) and cardiac muscle nutrition poisons was 54% (78/145). The efficacy rate of ACEI group was higher than that of cardiotonic medicine group and cardiac muscle nutrition poisons(χ2 = 16.28, 14.71, P< 0.0125). Conclusions The implement of health management and treatment intervention to Keshan disease patients is of great significant in improving the healthy condition of Keshan disease patients. Health education and life-style instruction as well as the use of ACEI, β-blockers and diuretic have comparatively obvious effect on treatment of chronic Keshan disease congestive cardiac failure.

The discovery of limbal stem cells is the key advancement in ophthalmology in the 20th century.Many clinical researches have proved that limbal stem cells transplantation is an effective method to treat severe ocular surface diseases.However, some important issues associated with the identification,isolation,standardized culture in vitro and differentiation after transplantation are still not clear and need to be paid more attention.Strengthening the underlaying research in this field will play important role in treating corneal blindness.

Objective To explore the effects of ?-tocopherol on Bcl-2 protein expression of spermatogenic cells in experimental varicocele rats. Methods Thirty adult male Wistar rats were randomly divided into 3 groups(n=10): treatment group (TG) was intramuscularly injected ?- tocopherol (0.5mg/100g body weight, one time daily for 4 weeks) after establishing varicocele model by partial ligation of the left renal vein for 4 weeks, operation control group (OCG)and sham operation group (SOG). After 8 weeks Bcl-2 protein expression in the testes tissues was detected by immunohistochemical method. Results The weight of left testes in TG was obviously heavier than that in OCG(P

Objective To observe the role of preoperative single administration of zenapax in the prevention of acute rejection after kidney transplantation, and evaluate its safety. Methods A total of 80 renal transplant recipients during the same period were divided into treatment and control groups, each group containing 40 patients. There were no difference between the two groups in treatment regime except the preoperative single administration of zenapax in the treatment group. Results Acute rejection rate was significantly lower in the treatment group(7.5%) than the control group(25%) within 6 months after kidney transplantation(P
