METHODS: The study consisted of 11 cases of IPSID and similar number of controls which included 11 of normal intestinal mucosa and 11 of high grade B cell lymphoma of ileum. The parameters analyzed included clinical profiles, biochemical and other laboratory investigations, radiologic and histological findings including immunohistochemistry. RESULTS: All IPSID cases had demonstrable serum IgA heavy chain and heavy mucosal plasma cell infiltration. According to Galian's histological staging, there were 4 patients with stage A and 7 with stage B. κ and ;λ light chains were over-expressed in 7 patients; 1 stage A patient had H pylori-positive active gastritis and eradication of H pylori led to disease remission. Stage A biopsies had higher expression for syndecan-1, while stage B had higher expression for bcl6 and p53. Syndecan-1,κ and λ light chains and IgA heavy chain showed inverse relationship with bcl6 and p53. All patients were treated with doxycycline. CHOP regime was added in 5 patients who developed frank lymphoma. Three died of the disease due to extensive organ infiltration. CONCLUSION: Certain immunomarkers like syndecan-1,κ and λ light chains and IgA heavy chain could be of much help in identifying early stage IPSID. Stage B IPSID showed higher expression for bcl6 and p53 than stage A IPSID. bcl6 and p53 expressions correlated with a more advanced disease stage and aggressive tumour behavior.展开更多

It plays a role as an inhibitor of cell death in cancer cells,thus facilitating the growth of these cells. In the case of gastric cancer,survivin is over-expressed in tumor cells and plays a role in the carcinogenesis process. Several studies on gastric cancer have indicated that there is a relationship between survivin expression and the ultimate behavior of the carcinoma. Since the expression pattern of survivin is selective to cancer cells,it has been described as an "ideal target" for cancer therapy. Currently,several pre-clinical and clinical trials are on-going to investigate the effects of interfering with survivin function in cancer cells as a biologic therapy. Survivin is a potentially significant protein in the diagnosis,prognosis and treatment of gastric tumors.展开更多

METHODS HS-AFP was separated and determined using native polyacrylamide electrophoresis with a discontinuous buffer system and Western blots. GGT Ⅱ was separated with native polyacrylamide electrophoresis with a discontinuous buffer system and detected by enzyme staining. Forty cases with HCC underwent serial determination of HS-AFP and GGT Ⅱ before and after radical excision. The correlations were analyzed between the two indices and survival time. RESULTS In the 40 cases with HCC, before radical excision the positive rates of HS-AFP and GGT II were 57.5% and 67.5% respectively, with the positive rate of combined HS-AFP and GGT Ⅱ reaching 80.0%. After operation, the recurrence and metastasis rate in the groups with positive HS-AFP and GGT Ⅱ were 90.9% and 58.8% respectively, while in the groups with negative HS-AFP and GGT Ⅱ the rates were 20.7% and 26.1% respectively. Recurrence and metastasis occurred in all cases with both postoperative positive HS-AFP and GGT Ⅱ but only in 9.5% of the cases in whom both postoperative HS-AFP and GGT Ⅱ were negative. Univariate analysis revealed that postoperative HS-AFP and GGT Ⅱ were related to the prognosis in HCC. CONCLUSION Postoperative serum HS-AFP and GGT Ⅱ are very useful in predicting the prognosis of HCC patients.展开更多
A case-control study involving 203 cases of pelvic endometriosis seen from 1987- 1989 , and 406 randomly selected and age-matched community controls was conducted in order to provide information relevant to effective ...A case-control study involving 203 cases of pelvic endometriosis seen from 1987- 1989 , and 406 randomly selected and age-matched community controls was conducted in order to provide information relevant to effective prophylxais of the disease. The diagnosis was confirmed by pathology from laparotomy and/or laparoscopy. A questionnaire focused on menstrual, marital and reproductive status , professional exposure and physical activities ,and the results were analyzed by a conditional logistic regression model. Women characterized by earlier menarche(≤ 12 years) and longer period(≥8 days) were found to be associated with an elevated incurring risk, and a trend of increasing risk associated with primary dysmenorrhea (RR =2. 1 for mild to moderate and RR= 5. 2 for severe dysmenorrhea), energetic physical activity during menstruation (RR =2. 1) , and allergic diathesis(RR=1 . 8) was seen. An inverse relationship was observed between the number of pregnancies and risk of endometriosis,and the protective effect was most significant when only the number of full-term pregnancies was counted.The risk factors of endometriosis are discussed, and intensive treatment of primary dysmenorrhea and avoidance of strenuous exercise during menstruation are identified as important measures in the prevention of endometriosis.展开更多
