Objective To investigate the correlation between HPV positive rate and incidence rate of cervical cancer.Methods 438 women,who reveived cervical Pap smears and biopsy,were included in the present study.Human papilloma virus nucleic acid amplification genotyping assay kit was used to detect 21 kinds of HPV subtypes.Results There were 102 patients with cervical cancer (23.29%) and HPV-positive 94 patients (21.46%),which had no significance difference (x2 =0.421,P =0.517).There were 56 patients HPV16 positive (54.90%),19 patients HPV58-positive (18.63%),12 patients HPV18 positive (11.76%) and 8 patients HPV52 positive (7.84%),which were significantly higher than those of other types of HPV-positive rate(all P < 0.05).The proportion of the patients with invasive cervical cancer in HPV i6,HPV58,HPV18,or HPV52-positive was significantly higher than that of intraepithelial lesions and carcinoma in situ (all P < 0.05).Conclusion HPV16,HPV58,HPV18,and HPV52 have high correlation with uterine cancer.
9.Expression and clinical significance of HA117 in adults with acute leukemia
Journal of International Oncology 2011;38(8):636-639
Objective To investigate the expression of HA117 in bone marrow mononuclear cells (BMMNCs) of acute leukemia patients, and its correlation with multidrug resistance( MDR), as well as its correlation with antigens presentation and its clinical significance. Methods HA117 gene expressions in 36 patients with acute myeloid leukemia (AML) and 14 patients with acute lymphocytic leukemia (ALL),10 patients with idiopathic thromnocytopenic purpura (ITP) were tested by using reverse transcriptase polymerase chain reaction (RT-PCR) technique. Thirty bone marrow specimens of AML patients at different phase were selected, and immunophenotypes were assayed by flow cytometry. ResultsThere was no significant difference ( P > 0.05 ) in HA117 gene expression between ALL (78.57%) and A ML (72.22%). The expressions of HA117 gene in both ALL and AML were significantly higher than in ITP patients ( P < 0.05 ). The HA117 gene was expressed in 75.00% of the initially diagnosed patients and 77.78% of the remission patients and 69.23% of the nonremission patients, all of them had higher expression than the patients with ITP, but there was no significant difference among the three groups. There were 47.06% and 87.88% with HA117 gene expressioned in non-resistance group and resistance group respectively, and the difference between the two groups was significant(P=0.005). HA117 had positively correlation with CD11b(OR =0.59, P=0. 001 ),CD33(OR=0.704, P=0. 000) expression in 30 patients of AML, and had negative correlation with MPO (OR=-0.611, P=0.001). ConclusionHA117 gene overexpression is significantly associated with the clinical resistance. It may also be associated with MDR of acute leukemia. HA117 gene can be used as an important indicator for investigating clinical MDR and predicting prognosis of acute Ieukemia patients. HA1 17 is closely related to CD11b, CD33, MPO expression in AML, and they can be used as biomarkers for evaluating therapy efficacy in AML.

In the present study, comparison have been made between two kinds of double labelling methods; single side labelling and both sides labelling. To make the different groups be comparable, all sections were continuously cut from the same specimen and all labelling processes were carried out at the same ti- me. The groups were divided as follows: A, one side anti-?-amylase labelling and one side antitrypsin labelling; B, single side labelling of anti-?-amylase and antitrypsin; C, one incubation with anti-?-amylase, followed by two incu- bations with protein A-gold (PAG) complexes of varied size, C1: 7nm and 20nm, C2: 10nm and 20nm, C3: 20nm and 7nm; D, single side labelling of anti- ?-amylase and an unrelated antiserum (antichathepsin D), applying free protein A between two labellings; E, as C, but with free protein A between two PAG incubations; F, as control. Group A and B showed that the two labelling me- thods had almost the same sensitivity.Group C indicated that the interaction of single side labelling were resulted from the combination of the second PAG with the free Fc region of the first antiserum. To decrease the interaction, it was necessary for the second PAG to be much larger than the first one.Group D de- monstrated that the interaction between the second antiserum and the first PAG was very feeble. Group E proved that free protein A could completely prevent the interaction of single side labelling method. The both sides labelling method avoids interaction, but mistakes resulting from the ultrastructural differences on two sides of the sections may happen. Which method to be selected is dependent upon what to be labelled.
