Objective To assess clinicopathological features and prognosis of patients with combined hepatocellular and cholangiocarcinoma (cHCC-CC). Methods Clinicopathological and follow-up data of 115 cHCC-CC patients confirmed pathologically in Liver Cancer Institute of Fudan University from 1995 to 2007 were analyzed. Kaplan-Meier method was used to calculate 1-,3- and 5-year survival rates and tumor-free survival rates. Survival curves were analyzed using the log-rank test. The factors that impacted the prognosis of cHCC-CC were estimated. Results In 115 cases, one was Allen's type A, one was Allen's type B, and the other 113 were Allen's type C. Being with male in predominance, most of the cHCC-CC patients had liver cirrhosis background. They presented with elevated AFP or CA19-9, vascular invasion, resembling hepatocellular carcinoma(HCC)as well as lymph nodes metastasis. One-, 3-, 5-year survival rates of 115 patients were 68. 1%, 38. 1% and 33.6%, respectively, with median survival time of 13.0 months. Whereas the 1-, 3-, 5-year survival rates in radical resected patients were 78.4 % ,44.4 % and 44.4 % ,respectively, with median survival time of 16.0 months. Tumor free survival time at 1-, 3- and 5-year was 57.8 %, 12.6 % and 0.0 %,respectively,with median recurrent time of 10.0 months. One-, 3-, 5-year survival rates of 10 nonsurgical patients were 10/10,10/10 and 0/10,respectively, with median survival time of 5.3 months.TNM stage was independent factor for prognosis of the patients after resection. Whereas the lymph nodes involvement was independent factor for the tumor free survival time of radical resected patients.Conclusions Although clinicopathological characteristics of cHCC-CC are more similar to those of HCC, the prognosis of cHCC-CC is more unfavorable than that of HCC. TNM stage is an independent determinant of long time outcome for patients after resection.

Objective To investigate the clinical, histopathological and immunopathological charac teristics of erythema annulare centrifugum (EAC). Methods A retrospective study was performed on 54 cases of EAC collected from 2001 to 2005. Information was gathered about patients' sex, age, disease course, distribution and morphology of eruptions, symptoms, complications. Also, the findings of histopathology and direct immunofluorescence examination in some patients were evaluated. Remits EAC most commonly occurred on the lower limb, and was usually complicated by various diseases among which mycosis predominated. Histological examination revealed compact lymphocyte infiltration in dermal vessels in 32 of these 54 patients. Direct immunofluorescence showed the deposition of IgG, lgM, or C3 on the walls of small vessels in 6 of 12 tissue samples tested. Conclusions EAC is a multifactorial disease, and it seems that the infiltration of lymphocytes and deposition of circulatory immune complex on small blood vessels in dermis may play important roles in its pathogenesis.

Objective To optimize the conditions of the expression of fusion protein GST-SjMP10 and to evaluate the value of fusion protein GST-SjMP10 for diagnosis of schistosomiasis.Methods The optimal concentration of IPTG for the expression of fusion protein GST-SjMP10 was chosen in inducing the expression of GST-SjMP10 with different concentration of IPTG,and the soluble fusion protein GST-SjMP10 was identified by SDS-PAGE.The fusion protein GST-SjMP10 was purified by chromatographic affinity with glutathione Sepharose 4B gel.The sensitivity and specificity of purified fusion protein GST-SjMP10 for diagnosis of schistosomiasis were determined by enzyme linked immunosorbent assay(ELISA)to detect the IgG antibody in sera from the patients with acute schistosomiasis,advanced schistosomiasis and clonorchiasis as well as healthy subjects.Results Most of the expressed fusion protein GST-SjMP10 was in soluble status when the concentration of IPTG was reduced to 0.1 mmol/L and the fusion protein GST-SjMP10 could be purified by chromatographic affinity.The positive rate of anti-GST-SjMP10 antibody in the sera from the patients with acute and chronic schistosomiasis japonica was 97.5% and 96.7% respectively.No cross reactivity of the fusion protein GST-SjMP10 was found in the detection for the sera from clonorchiasis patients,and no false positive was found in the detection for the sera of healthy subjects.Conclusion The fusion protein GST-SjMP10 was expressed successfully and showed high sensitivity and specificity for the diagnosis of schistosomiasis japonicum.

Objective To investigate the value of recombinant fusion protein (GST-HD)of the large hydrophilic domain (HD) of 23 kDa membrane protein of Schistosoma japonicum with the Glu-tathione-S-transferase (GST) of S. japonicum for early diagnosis of schistosorniasis. Methods The rabbits were infected with cercariae of S. japonicum Chinese mainland strain (300 per one). The rabbits' sera before infection and after being infected at different time were collected. The antibodies IgG(s) against recombinant GST-HD and SEA were measured respectively by ELISA to observe the rabbits' immune reaction status to GST-HD and SEA at different time after being infected with the cercariae. At the same time, 90 serum samples of patients with acute schistosorniasis and 30 samples of healthy persons were checked with GST-HD to evaluate its value for early diagnosis of schistosorniasis. Results At the 17th, 21st and 24th day after infection, the positive rates of antibody IgG of rabbits sera against GST-HD were 42.85%, 92.80% and 100.00% respectively, but the positive rates of antibody IgG against SEA were 14. 28% , 50. 00% and 84.60% respectively. The sensitivity of GST-HD for detecting early schistosome infection was higher than that of SEA significantly. The predictive values of positive and negative of GST-HD for detecting acute schistosorniasis was 98. 89% and 96.67%,respectively, and the diagnostic efficacy was 98. 33%. Conclusion The recombinant GST-HD fusion protein has high early diagnostic value for schistosorniasis.

Objective To screen the bacteria and its components which are toxic to Oncomelania hupensis. Methods The samples of Oncomelania hupensis on the point of death and the soil around the snails were collected. The bacteria existing in the snails and soil were isolated and identified by using regular methods. After being fermented, the toxicity of the bacterium components including the ferment supernatant, split products and bacteria to the snail were tested by the toxicity test. Results Totally, 104 strains of bacteria were isolated from the snails and soil samples, which included Gram positive cocci or bacilli, Gram negative cocci or bacilli. The fermenting supernatant, splitting products and 10 strains of bacteria showed different level of toxicity against the snail respectively. All the fermenting supernatant of bacterium PY1-1, PY7-2, PY3-5, PY19-3, PY2-2-2, PY8-2-2, PY16-1 could kill more than 50 percent of snails. Conclusion The bacteria which are poisonous to snails have been isolated that make a good basis for identifying single toxic component against snails.
