Objective To analyze the clinical effects of internal radiation of iodine-125 seed implantation in the treatment of advanced pancreatic carcinoma.Methods 22 patients with unresectable and advanced pancreatic carcinoma were treated by the internal and interstitial radiation using iodine-125 seed implantation.Results Survival of 20 months was observed in 5 patients,10 ～ 20 months in 9 patients,2 ～10 months in 8,patients with an average of (13.47 ± 8.12) months.Among the 22 patients,complete response was obtained in 5 patients,partial response in 8 patients,no response in 7 paticnts,and the other showing PD.The response rate( CR + PR) was 59％.Conclusions Intra - operative internal radiation by iodine - 125 seed implantation does show some therapeutic effects for advanced pancreatic carcinoma.

Objective To investigate the significance of the expression of interleukin-10(IL-10),interleukin-13(IL-13)and interleukin-15(IL-15)in serums of patients with hepatitis B.Methods The expression of IL-10,IL-13 and IL-15 in serums of 109 patients was measured by ELISA.Results The serum levels of IL-10,IL-13 in patients with moderate degree chronic hepatitis B(CHB)group were significantly higher than that in patients with chronic severe hepatitis group,severe degree CHB group,acute hepatitis group and normal group.The serum level of IL-15 was increased in patients with acute hepatitis、moderate degree CHB group,severe degree CHB group and chronic severe hepatitis compared with normotensives.The proportion of IL-15/IL-10 and IL-15/IL-13 in patients with chronic severe hepatitis group,severe degree CHB group and acute hepatitis group were higher than that in patients with moderate degree CHB group and normotensives.The serum level of IL-15 and the proportion of IL-15/IL-10 and IL-15/IL-13 in dead group were significantly higher than that in improving group with chronic severe hepatitis.Conclusion There is an abnormal cell-mediated immune response in patients with hepatitis B.Combining detection on the levels of serum IL-10,IL-13 and IL-15,and the proportion of IL-15/IL-10 and IL-15/IL-13 would nicely show the cellular active status and be helpful to the prediction of prognosis and direction of therapy in patients with hepatitis B of different kinds of clinical type.

Objective To study the changes of hematological indices of blood donors after 400ml whole-blood donation.Methods Blood specimens of 123 healthy donors were collected before donation,1 day,7 days,1 month,and 3 months after donation.The dynamic changes of WBC,RBC,hemoglobin,hematocrit,Plt,plasma total protein,albumin and blood serum iron were observed.Results After donation,the changes of WBC,Plt,total protein of blood plasma and albumin showed no significant change.The levels of RBC,hemoglobin,hematocrit and blood serum iron returned to normal after 3 months.Conclusion For anyone who meets the health standard of blood donors,to donate 400ml whole blood at 3-month interval is harmless.

Objective To analyze the clinicopathological features of bilateral primary breast cancer (BPBC) by molecular subtypes.Methods Clinical data of 145 BPBC patients were reviewed focusing on the clinicopathological features of different molecular subtype and the concordance of molecular subtype between first and second primary breast cancers.Results Of the first primary breast cancers ( FPBC),91 cases (62.8％ ) were Luminal A subtype,Luminal B subtype in 13 cases (9.0％ ),Human epidermal growth factor receptor 2 (HER-2) subtype in 14 cases (9.7％ ),triple negative breast cancer (TNBC) in 27 cases ( 18.6％ ).Of the second primary breast cancers ( SPBC ),Luminal A subtype was found in 93 (64.1％ ) cases,Luminal B subtype in 10(6.9％ ) cases,HER-2 subtype in 14(9.7％ ) cases and TNBC in 28( 19.3％ ) cases.Most TNBC patients were young ( age ≤ 50 ) with high frequency of grade Ⅲ in FPBC.Molecular subtypes do not vary with tumor size,clinical stage,lymph node status and pathological types ( P ＞ 0.05 ).Most FPBC of Luminal A and TNBC were concordant same subtypes in SPBC ( K ＞ 0.04 ),while Luminal B and HER-2 subtypes often had discordant phenotypes in SPBC ( K ＜ 0.04).BPBC were more likely to have concordant subtypes if the two tumors developed in short time interval.Conclusions The distribution and clinical leatures of each subtype in BPBC is similar to unilateral breast cancer.Patients whose FPBC are Luminal A or TNBC often have concordant phenotypes for their SPBC,a short time interval between two cancers also predicts concordance.

Objective To investigate the change of the mitochondrial aspartate aminotransferase (mAST), and the ratio of m-AST and aspartate aminotransferase (AST) in rat orthotopic liver transplantation.Methods We used the rat autologous orthotopic liver transplantation modelin which liver was infused by portal vein. Group A: Autologous orthotopic liver transplantation. Group B: Sham control group of normal rats. To measure the m-AST, AST and ALT in rat serum at each time, the ratio of m-AST/AST was calculated to observe the changes after surgery. Results The ALT of group A after 1 h was 1149.2 U/L, while the ALT of group B was 111.3 U/L; The AST of group A ofter 1 h was 819.5 U/L, while the AST of group B was 128.2 U/L; The m-AST of group After 1 h was 290.8 U/L, while the m-AST of group B was 40.5 U/L. The levels of m-AST, AST and ALT in group A were significantly higher than group B (P ＜ 0. 05).Group A significantly increased the degree of liver damage compared with group B. The ratio of m-AST/AST in group A changed with time obviously. Because the haff-life of m-AST in serum was shorter than that of AST, and AST in this study returned to normal slowly, the ratio of m- AST/AST in A group decreased after 6 h and the number is 0. 12. It indicating that the damage of mitochondria in rat liver cells has been restored after 6h. Conclusions It will be better to judge the prognosis of liver transplantation from the changes of serum m-AST in rats. And it seems earlier to reflect the injury or recovery of liver cell compared with AST.It also has the guiding values to diagnose and treat the damage of liver cells and mitochondrial in the rat liver transplantation.

Objective To evaluate the efficacy and toxicity for the protocol of low-dose harringtonine and cytarabine(HA regimen)in combination with granulocyte colony-stimulating factor(G-CSF)in elderly patients with acute myelogenous leukemia(AML).Methods Thirty-five AML patients were treated with HAG including low-dose chieved PR.The overall response rate was 83%.5 of 35(14%)was non-remiasion.Two patients died in the duration of treatment.The main complication of chemotherapy is myelosuppresion.Conclusion Low-dose HA regimen in combination with G-CSF is effective and safe in elderly patients with AML.

Objective To investigate the expression of CD24 and FAK in the invasive breast ductal carcinoma tissues and their clin-ical significance. Methods Tissues were obtained from 86 patients with breast carcinoma and 30 non-cancer specimens. The expression of CD24 and FAK was detected by immunohistochemical technique (ElivisionTMPlus) and their correlation with tumor clinicopathological char-acters was analyzed. Results The positive rate of CD24 and FAK expression in 86 cases of breast carcinoma was 87.2% (75/86) and 72.1% (62/86) respectively, which was significantly different from that in control group(P<0.01). Expression of CD24 was significantly correlated with axillary lymph node metastasis(P<0.01). Expression of FAK was correlated with histopathologic grade, axillary lymph node metastasis and clinical stage (P<0.05). There was a positive correlation between the expressions of CD24 and FAK in breast carci-noma tissues (rs = 0.222, P < 0.05). Conclusion Expression of CD24 and FAK are closely correlated with the development of breast carcinoma and there is a markedly positive correlation between CD24 and FAK expression. These indexes can be helpful in understanding the biological behaviors and predicting the prognosis of breast carcinoma.
