[Abstract]:Objective:
To investigate the expression of small molecule RNA-96 (microRNA-96, miR-96) in the tissues of Uterine cervical cancer (UCC) and its relationship with the clinicopathological features, and to explore the effect of neoadjuvant chemotherapy on the expression of miR-96 in cervical squamous cell carcinoma, and the changes in the expression of miR-96 and the efficacy and sensitivity of the neoadjuvant chemotherapy. The relationship between the common pathological features of the clinic to evaluate the predictive value of the therapeutic effect and sensitivity in chemotherapy, the relationship between the expression of miR-96 in the tissues of cervical cancer patients and the TCM syndrome differentiation of cervical cancer, and to evaluate the value and Prospect of the combination of traditional Chinese and Western medicine in the clinical treatment of cervical cancer.
Stem-loop quantitative real timePCR (qPCR) was used to determine the expression of miR-96 in 52 cases of cervical malignant tumor, 28 cases of cervical normal patients and 28 cases of cervical squamous cell carcinoma (I B2 phase II a phase) before and after neoadjuvant chemotherapy and posterior swelling in 28 cases of cervical squamous cell carcinoma. The expression of miR-96 in the tumor tissue; statistical analysis of the relationship between the expression level of miR-96 and the clinicopathological features and the correlation between the expression of miR-96 and the curative effect, sensitivity and clinicopathological features of the neoadjuvant chemotherapy, and the analysis of the expression of miR-96 in cervical cancer by TCM syndrome differentiation.
The relative expression of miR-96 in the tumor tissues of 1.52 patients with cervical cancer was 45.59 (15.19139.61) significantly higher than that in 28 cases of normal cervical tissue (0.78,1.11), and the difference was statistically significant (p=0.000).
The relative expression of 2.MiR-96 in the tissues of patients with cervical cancer was closely related to the clinicopathological features (clinical stage, histological type, cytological classification, infiltration depth, lymph node metastasis). In the middle, the relative expression of 61.61 (17.74183.42) in the low differentiated carcinoma was significantly higher than that of the highly differentiated carcinoma (6.13,66.67), and the difference was statistically significant (p=0 The relative expression of.005 in adenocarcinoma was 155.67 (57.77270.61), which was significantly higher than that of squamous carcinoma (13.35,91.00), (p=0.004). The relative expression of miR-96 in the tissues of patients with stage I, stage II, and stage III to IV of cervical cancer was 15.41 (7.52,26.26), 85.15 (68.32194.76) 462.08 (422.571028.65) and stage III to IV significantly higher than stage I, stage II (P). =0.000, p=0.001), the stage II was significantly higher than phase I, and the difference was statistically significant (P=0.000), the relative expression of the lymph node metastasis group was 163.46 (28.95205.62) significantly higher than that in the non lymph node group (6.99,22.61), (p=0.000), and the infiltration depth was 24.72 (14.44141.79), which was significantly higher than that of 1/2 (14.44141.79). The interstitial mass was 13.79 (5.14,25.649), (p=0.025), but not significantly related to the age of the patients (p=0.385).
The expression level of miR-96 in 3.28 cases of cervical squamous cell carcinoma was significantly decreased after neoadjuvant chemotherapy, and the relative expression of miR-96 in cervical cancer tissues before neoadjuvant chemotherapy was 3.40 (2.01,6.86) times of the tumor tissue after chemotherapy, and the difference was statistically significant (p=0.000).
4. before the neoadjuvant chemotherapy of cervical squamous cell carcinoma, the relative quantitative results of miR-96 expression in the posterior tumor tissues were closely related to the clinicopathological features: the degree of cell differentiation was in the middle, the low differentiation 2.51 (1.21,33.26) was 8.22 (5.21,15.39) lower than that of the high differentiation (p= 0), and the interstitial infiltrating depth of the interstitial 1/2 was 5.66 (4.06,14.09). 1.91 (0.90,2.96) (p=0.000) and 1.79 (0.86,2.64) with lymph node metastases were significantly lower than those of 1/2 (0.86,2.64) with lymph node metastases, and 5.43 (4.04,12.84) (p=0.000) were lower than those without lymphatic metastasis, while the age was less than 45 years and 45 years old, and the clinical stage was I B2 stage, and there was no statistical difference in the changes of miR-96 expression in the patients with stage II a (P0.05).
5. the effective group of neoadjuvant chemotherapy (CR+PR) was compared with the ineffective group (SD+PD): the expression level of miR-96 in the tumor tissues of the effective group decreased significantly (p=0.000). There was no significant difference in the expression of miR-96 in the tumor tissues (P0.05) before chemotherapy (P0.05); the expression level of miR-96 in the tumor tissues before the neoadjuvant chemotherapy was clear. The expression level of miR-96 in the effective group after neoadjuvant chemotherapy was significantly lower than that in the ineffective group (p=0.001), which was significantly lower than that in the ineffective group (p=0.001).
6. the relative expression of miR-96 in the tumor tissue of the cervical squamous cell carcinoma patients before the neoadjuvant chemotherapy and the three dimensional ultrasound parameter blood index (FI), the angiogenic index (VI), the blood vessel blood flow index (VFI), the percentage of the residual tumor volume after chemotherapy (P0.05), and no significant correlation with the tumor volume before chemotherapy (P0.05).
7. the relationship between the expression level of miR-96 in the tissues of the patients with cervical cancer and the syndrome differentiation of traditional Chinese medicine: the expression level of miR-96 in the tumor tissues of the patients with spleen and kidney yang deficiency is significantly higher than that of the liver qi stagnation, and the difference is statistically significant (P0.05), while the spleen kidney yang deficiency and the liver kidney yin deficiency patients are in the tumor tissue of miR-9. 6, there was no significant difference in the expression of miR-96 in tumor tissue between liver qi stagnation type and damp heat stasis type (P0.05).
1.MiR-96 is highly expressed in cervical cancer, and its expression level is closely related to the clinicopathological features of the patients, suggesting that it may play the role of the oncogene in the development of cervical cancer, and is closely related to the evolution and poor prognosis of cervical cancer.
2. neoadjuvant chemotherapy can effectively reduce the expression of miR-96 in the malignant tumor tissues of the cervix. The expression of miR-96 in the tumor tissue before chemotherapy is closely related to the sensitivity of chemotherapy and the clinical efficacy. Therefore, the determination of the expression level of miR-96 in the cervical cancer tissues before chemotherapy is of reference value for the therapeutic effect and sensitivity prediction of the neoadjuvant therapy.
3. the expression level of miR-96 in the tumor tissues of the patients with cervical cancer is closely related to the TCM syndrome differentiation: the expression level in the spleen kidney yang deficiency type, the liver kidney yin deficiency syndrome type is obviously higher than the liver qi stagnation type, the damp heat stasis syndrome type.
