0.05).The medical expenses of the Hysteroscopic Group was significantly lower than that of the Laparoscopic Group(t=-85.584,P=0.000).Conclusions As compared with laparoscopic conservative operation,hysteroscopic tubal catheterization with MTX injection is another simple,cost-effective,and minimally invasive alternative for early tubal pregnancy.

Objective To evaluate the values of combined detection of soluble mesothelin related proteins (SMRP)and carbohydrate antigen 1 25 (CA1 25)in the diagnosis of malignant peritoneal mesothelioma.Methods 20 patients with malignant peritoneal mesothelioma were selected as the malignant group,50 patients with benign ovar-ian tumor were selected as the benign group,60 healthy women were selected as the control group.Enzyme -linked immunosorbent assay(ELISA)was adopted to detect serum SMRP levels and electrochemiluminescence immunifaction (ECLI)was adopted to detect serum CA1 25 levels.The SMRP,CA1 25 levels were compared among all groups,the sensitivity,specificity of SMRP and CA1 25 in the diagnosis of peritoneal malignant mesothelioma were analyzed. Results Serum levels of SMRP,CA1 25 in malignant group were (1 4.8 ±1 .6 )μg/L,(1 89.1 ±1 5.3 )μg/Lrespectively,which were significantly higher than those in the benign group[(3.9 ±0.9)μg/L,(28.6 ±4.2)μg/L] (t =27.40,49.61 0,all P <0.01 )and the control group[(2.8 ±0.7)μg/L,(1 6.9 ±3.8)μg/L](t =29.877, 53.334,all P <0.01 ).The sensitivities of SMRP,CA1 25 detection alone for malignant peritoneal mesothelioma diag-nosis were 65.0%,50%,respectively,while their specificities were 83.6%,79.1 %.The sensitivity and specificity of combined detection of SMRP and CA1 25 for malignant peritoneal mesothelioma were 95.0% and 93.6%.Conclusion SMRP has some value in the diagnosis of peritoneal malignant mesothelioma.SMRP combined with CA1 25 detection can markedly improve the diagnostic sensitivity and specificity for malignant peritoneal mesothelioma.

OBJECTIVE: To explore the diagnostic value of human papillomavirus E6/E7 mRNA for residue and recurrence of cervical intraepithelial neoplasia (CIN) patients after cervical conization.
 METHODS: A total of 154 patients, who underwent cervical conization and possessed complete follow-up data of high-grade cervical intraepithelial neoplasia (CINII, III), were subjected to thin-prep cytology test (TCT), HPV-DNA typing and HPV E6/E7 mRNA test in 3-6 months and 12 months after cervical conization. Abnormal cytology (≥ASC-US) or high-risk HPV-DNA (+) or HPV E6/E7 mRNA (+) cases were found by colposcopy and cervical biopsy pathological diagnosis.
 RESULTS: Nine patients had residue and 22 recurred. HPV-DNA detections after cervical conization in 57 patients were positive. Among them, 30 patients had residual/recurrent lesions. HPV E6/E7 mRNA detections in 26 patients were positive. Among them, 24 patients had residual/recurrent lesions. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosis in the detection of HPV-DNA were 96.8%, 78%, 52.6%, 99%, and 81.8%, respectively. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of diagnosis in the detection of HPV E6/E7 mRNA were 77.4%, 98.4%, 92.3%, 94.5%, and 94.2%, respectively. The specificity and positive predictive value of HPV E6/E7 mRNA test were greater than those of HPV-DNA typing test. There was a significant difference between the two groups (P<0.05).
 CONCLUSION Detection of HPV E6/E7 mRNA during the follow-up period could timely and effectively forecast the risk of residue and recurrence of CIN after cervical conization, and reduce excessive examination and treatment.

MiRNAs are short, noncoding RNAs that modulate gene expression at the posttranscriptional level and induce the degradation of the mRNA transcript or the inhibition of protein translation. Dicer is an endoribonuclease in the RNase III family that is essential for the production of miRNAs. The abnormal expression of Dicer is frequently found in the occurrence and development process of many kinds of tumors, which is closely related to the treatment and prognosis of tumor.
