Serum specific IgG (SIgG) antibodies of 32 patients with epidemic hemorrhagic fever (EHF) were sequentially determined by indirect immunofluorecent antibody test and their relationship to the types of the disease were analyzed in the present paper. The SIgG antibodies appeared practically on day 3 after the onset of the disease. Thereafter,the positive rates and the SIgG titres increased with the prolongation of the illness days and reached 100% positive rates and stable high titres till day 11 to day 12 after the onset of the disease. Furthermore, different types of the disease had.different SIgG response curves ,and there was a significant difference between the SIgG titres of different illness types statistically from day 7 to day 8 after the onset of the disease. These results suggest that the SIgG might be responsible for the immunopathogenesis of EHF.

0 05). The detective rate of (85 7%) CgA in the P53 protein positive group(21 cases) was significantly higher than that of 54 5% the P53 protein negative group(55 cases). Conclusions The positive rate of CgA was increased with corresponding to the lower down of differentiation grades . Very close relationship is found between the expression of P53 protein and the incidences of CgA positive cell. It suggested that the expression of P53 protein might play an important role in neuroendocrine differentiation in ovarian mucinous tumors.

Objective To investigate the expressions of Snail mRNA and E-cad mRNA in invasive ductal carcinoma and their clinical significance. Methods The expression of Snail mRNA and E-cad mRNA were detected on mammary gland hyperplasia (30cases), intraductal breast carcinoma(30cases) and invasive ductal carcinoma (70cases)by in situ hybridization. Results The positive expression rate of Snail mRNA and E-cad mRNA in mammary gland hyperplasia, intraductal breast carcinoma and invasive ductal carcinoma were 23. 3% ,46. 7% ,81.4% and 96. 7% ,66. 7% ,35.7% ,respectively. There was significant difference among them(P < 0. 01). There was difference between Snail mRNA and E-cad mRNA in the same group(P <0. 05). Snail mRNA was not related to age, tumor size or histopathological grade (P >0. 05) ,but it was related to lymphatic metastasis (P <0. 01). E-cad mRNA was not related to age, tumor size(P >0. 05),but it was related to lymphatic metastasis and histopathological grade(P <0. 01). There were positive relationship between Snail mRNA and E-cad mRNA(r = -0. 56, P =0. 00). Conclusions The overexpression of Snail mRNA and low expression of E-cad mRNA were involved in the infiltration and metastasis of breast carcinoma, and they were related to lymphatic metastasis. Therefore, the test of the expression of them were valuable in predicting the prognostic and metastasis of breast carcinoma.

Objective To compare the efficacy and side-effects of preoperative neoadjuvant uterine arterial chemoembolization and venous chemotherapy in treating cervical cancer in young female patients. Methods A total of 241 young females(≤35 years old) with cervical cancer were enrolled in this study. The clinical data were retrospectively analyzed. The patients were divided into group A (n=63) and group B (n=57). Patients in group A received preoperative neoadjuvant uterine arterial chemoembolization with subsequent surgery, while patients in group B were treated with preoperative neoadjuvant intravenous chemotherapy followed by surgery. The chemotherapy scheme included carboplatin (50 mg/m2) and gemcitabine (1 000 mg/m2). The short-term effect, the amount of blood loss during the surgery, pathological findings and the side-effects of the two groups were compared. The Kaplan-Meier method was used to calculate survival rate, and the log-rank test was used for survival difference analysis. Results The short-term response rate of group A was 90.5%, which was significantly higher than that of group B (71.9%), the difference between the two groups was statistically significant (χ2=7.5, P<0.05). The resection rate of group A was 95.2%, which was higher than that of group B (84.2%). The amount of intra-operative blood loss of group A and group B was (443±263) ml and (695±312) ml respectively, the difference was statistically significant (t=4.802, P<0.05). The pathological complete remission of group A and group B was 9.5%(6/63) and 5.3%(3/57)respectively; the differences in postoperative pathological results between the two groups were statistically significant (χ2=12.3, P<0.05). The side effect of group A was milder than that of group B (P<0.05). The 5-year progression-free survival (PFS) rate of group A and group B was 73.0% and 54.4% respectively (χ2=4.471, P<0.05);and the overall survival (OS) rate of group A and group B was 77.8%and 63.2%respectively (χ2=3.022, P>0.05). In both groups, the clinical stage, the pathological grade and the size (≥ 4 cm) of the tumor were the main factors that could influence the prognosis in young females with cervical cancer (P<0.05). Conclusion The short-term efficacy of preoperative uterine artery chemoembolization is better than that of preoperative intravenous chemotherapy for the treatment of cervical cancer in young female patients. Besides, this therapy carries mild side effect, and it can improve the 5-year progression-free survival rate, although the long-term survival rate has not been obviously improved.
