It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.

BACKGROUNDA few inflammatory markers were studied to evaluate their possible prognostic roles in various cancers. The neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio are hypothesized to reflect the systemic inflammation. The objective of the present study was to investigate whether or not the pretreatment neutrophil-to-lymphocyte ratio or platelet-to-lymphocyte ratio can predict the survival of patients with cervical cancer treated with neoadjuvant chemotherapy and radical hysterectomy.

METHODSWe performed a retrospective study on cervical cancer patients (FIGO stage Ib2-IIb) who had undergone neoadjuvant chemotherapy and radical hysterectomy at Peking Union Medical College Hospital between January 1999 and December 2010. Data on demographics, clinical prognostic markers and histopathology were collected and analyzed. Univariate and multivariate analyses for prognostic factors were performed.

RESULTSA total of 111 patients were identified. The median neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios were 2.4 and 142.2, respectively. Overall survival and progression-free survival were neither significantly different between patients with high and low neutrophil-to-lymphocyte ratio (P = 0.149 and P = 0.108) nor in high and low platelet-to-lymphocyte ratio (P = 0.336 and P = 0.510). On multivariate analysis, lymph node status (P = 0.000 and P = 0.007) and lymphovascular space involvement (P = 0.001 and P = 0.001) were independent prognostic factors of progression-free survival and overall survival.

CONCLUSIONSLymph node status and lymphovascular space involvement were found to be independent prognostic factors for patients with cervical cancer who underwent neoadjuvant chemotherapy and radical hysterectomy. The pretreatment neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios seemed not to predict the survival of patients with cervical cancer treated with neoadjuvant chemotherapy and radical hysterectomy.

This study was aimed to analyze the correlation between CT perfusion parameters, e. g. perfusion (PF), blood volume (BV), peak enhancement image (PEI), time to peak (TTP), and the microvessel density (MVD) of cervical cancer. CT perfusion scans were carried out in 31 patients with cervical cancer. After their surgical resections, we obtained 31 cases of cervical cancer specimens, and 15 cases of adjacent normal cervical specimens as control group, then these 46 specimens were used in MVD detection through immunohistochemical CD34 staining. The MVDs of the tumor group were significantly higher than those in the control group, and the former seems to increase with the clinical stages with a positive correlation. The PF and PEI values have positive correlations with corresponding MVD values. The PF value of squamous carcinoma group has correlation with corresponding MVD value. The PF and PEI values of poorly differentiated group have correlations with corresponding MVD values. The PF, PEI and BV values of II-III stage group are positively correlated with corresponding MVD values. The PF value of lymph metastasis or non-lymph metastasis group both have correlations with corresponding MVD values. We found that CT perfusion parameters were positively correlated with corresponding MVD values in cervical cancer. Our results suggest that CT perfusion is a new method which could reflect tumor angiogenesis, histological malignant grade, invasion, and clinical stage. It will help us determine the tumor staging and prognosis.

OBJECTIVETo explore the interaction of folate deficiency and aberration of DNA methyltransferase 1 (DNMT1) in the progression of cervix carcinogenesis.

METHODSAll clinical samples were collected from 80 patients with cervix squamous cell carcinoma (SCC), 105 patients with cervical intraepithelial neoplasm (CINI, n = 52; CINII/III, n = 53) and 53 patients with cervix inflammation (CI). The participants were diagnosed by histology at Shanxi Province Tumor Hospital and Second Hospital of Shanxi Medical University during the period of September 2009 to May 2010. Meanwhile, cervical cancer cell lines Caski and C33A were treated with different concentration of folate. Radioimmunoassay (RIA), Western blotting and real-time PCR were used to detect the levels of serum folate, the expression of DNMT1 protein and mRNA, respectively. The data were analyzed by Student t test, ANOVA, chi-square test and Spearman correlation using SPSS statistical package. The correlation strength between factors and cervical canceration was calculated by OR and 95%CI value. Interaction effect was evaluated by the application of additive effect model.

RESULTSThe levels of serum folate (median inter-quartile range) were (2.66 ± 1.82), (2.83 ± 2.23), (3.17 ± 1.91) and (3.21 ± 1.74) ng/ml, the levels of DNMT1 protein (x(-) ± s) were 2.28 ± 0.55, 1.84 ± 0.37, 1.33 ± 0.38 and 0.92 ± 0.29, the Ct-ratio (Ct value of DNMT1/Ct value of β-actin) of DNMT1 mRNA (x(-) ± s) were 1.26 ± 0.13, 1.27 ± 0.12, 1.27 ± 0.12 and 1.33 ± 0.11 in the group of SCC, CINII/III, CINIand CI, respectively. The results showed that the serum folate levels were descended, and the expression levels of DNMT1 protein (χ(2)(tend) = 50.80, P < 0.05) and mRNA (χ(2)(tend) = 17.63, P < 0.05) were increased steadily with the severity of the cervix lesions. Moreover, our results revealed that there was an additive interaction between folate deficiency and high-expression of DNMT1 protein related to the risk of CIN and SCC. And it showed that the relative excess risk of interaction (RERI), attributable proportion of interaction (API) and synergy index(S) was 0.27, 0.14 and 1.40 in CINI group, 0.47, 0.19, 1.46 in CINII/III group, 1.60, 0.31, 1.61 in SCC group, respectively. It was found that folate was able to reduce the proliferation of Caski and C33A cells (r values were 0.954 and 0.969, all P values < 0.05), with 11.4% and 13.6% of growth inhibition at the concentration of 10 µg/ml, 64.8% and 49.4% at 1000 µg/ml in Caski and C33A cells, respectively. The result showed there was an inverse correlation between the levels of folate and DNMT1 protein (r values were -0.859 and -0.914, all P values < 0.05), with 1.96 and 1.92 of expression levels at the concentration of 10 µg/ml, and 1.60 and 1.38 at 1000 µg/ml in Caski and C33A cells, respectively. At folate concentration of 1000 µg/ml, the expression of DNMT1 protein or mRNA was higher in Caski cell than in C33A cell (t values were -4.22 and 3.50, all P values < 0.05).

CONCLUSIONOur finding indicated that the low levels of serum folate and high-expression of DNMT1 protein or mRNA seemed to be associated with high risk of cervical cancer and cervix precancerous lesion. Sufficient folate is able to effectively inhibit the growth of cervical cancer cells in vitro, and would counteract transcriptional and posttranscriptional aberration of DNMT1. It suggested that there might be a synergistic action between folate deficiency and aberration of DNMT1 in the progression of cervix carcinogenesis.

OBJECTIVETo investigate the feasibility of unilateral or bilateral nerve-sparing radical hysterectomy and evaluate the recovery of bladder and bowel function postoperatively.

METHODSFrom August 2008 to October 2009, sixty-one patients with cervical cancer stage Ib1 to IIa underwent radical hysterectomy (33 cases) and nerve-sparing radical hysterectomy (28 cases). Unilateral nerve-sparing radical hysterectomy was performed in 10 patients, and bilateral nerve-sparing radical hysterectomy (BNS) was performed in 18 patients. The data of operation time, blood loss, postoperative hospital stay days, residual urine volume, and postoperative complications were collected. The postoperative recovery of bladder and bowel function was evaluated.

RESULTSThere were no significant differences between nerve-sparing radical hysterectomy (NSRH) and radical hysterectomy (RH) groups in operation time [NSRH: (224.5 ± 40.0) min, RH: (176.4 ± 30.0 min)], blood loss [NSRH: (464.3 ± 144.0) ml, RH: (374.2 ± 138.7) ml], postoperative hospital stay days [NSRH: (8.4 ± 2.0) d, RH: (9.2 ± 1.8) d, and residual urine volume [NSRH: (64.8 ± 16.9) ml, RH: (70.6 ± 16.0) ml]. There were also no significant differences between UNSRH and BNSRH groups in operation time [UNSRH: (208.5 ± 28.5) min, BNSRH: (233.3 ± 43.1) min], blood loss [UNSRH: (440.0 ± 104.9) ml, BNSRH: (477.8 ± 162.90) ml], postoperative hospital stay days [UNSRH: 9.1 ± 1.8) d, BNSRH: (8.7 ± 2.1 d], and the residual urine volume [UNSRH: (68.3 ± 12.5) ml, BNSRH: (62.8 ± 20.0) ml]. There was a significant difference in the time of the Foley catheter removal between NSRH [(12.4 ± 5.2) d] and RH [(22.4 ± 9.7) d] groups. There was a significant difference in the time of the Foley catheter removal between UNSRH [(18.2 ± 3.6) d] and BNSRH [(9.1 ± 2.0) d] groups. During the postoperative 3 weeks follow-up, the patients in the NSRH group had a higher rate of satisfaction at urination and defecation (100%, 75%) than the RH group (54.5%, 24.2%).

CONCLUSIONUNSRH and BNSRH are safe and feasible techniques for early stage cervical cancer, and may significantly improve the recovery of bladder and rectal function.

BACKGROUND AND OBJECTIVEPelvic lymph node metastasis is an important prognostic factor of cervical cancer. The prognosis of cervical cancer patients with common iliac lymph node metastasis is poor, but few systematic studies have been reported . This study was to investigate the characteristics, risk, treatment and prognosis of stage IB-IIB cervical carcinoma patients with common iliac lymph node metastasis.

METHODSA total of 960 patients with cervical cancer receiving radical hysterectomy and bilateral pelvic lymphadenectomy were selected from the hospitalized patients in the Cancer Center of Sun Yat-sen University between January 1995 and December 2005, and analyzed retrospectively.

RESULTSOf the 960 patients, 288 (30.0%) had pelvic lymph node metastasis, and 45 (4.7%) had positive common iliac lymph node. The 5-year overall survival rate (OS) of patients with common iliac lymph node metastasis was 46.1%, and 67.5% in patients with other pelvic lymph node metastasis (P < 0.05). Univariate analysis showed that clinical stage, serum level of squamous cell carcinoma antigen (SCC-Ag) > 4 microg/L before treatment, depth of cervical invasion > or =2/3 and positive parametrial margin were associated with common iliac lymph node metastasis (P < 0.05). Patients with > or =3 pelvic lymph node metastasis (excluding common iliac lymph node) or recurrence had poor prognosis (P < 0.05). Factors predictive of common iliac lymph node metastasis on Logistic forward regression were SCC-Ag > 4 microg/L (P = 0.026, OR = 2.303) before treatment and positive parametrial margin (P = 0.045, OR = 2.634).

CONCLUSIONSCervical cancer patients with common iliac lymph node metastasis had poorer prognosis compared with patients with other pelvic lymph node metastasis. SCC-Ag >4 microg/L before treatment and positive parametrial margin were the independent predictive factors for common iliac lymph node metastasis of cervical carcinoma. Pelvic lymph node metastasis (excluding common iliac lymph node) > or = 3 or recurrence was prognostic factors for patients with common iliac lymph node metastasis.

OBJECTIVETo assess the feasibility of nerve sparing radical hysterectomy (NSRH) technique and the impact on the improvement of postoperative bladder function in patients with cervical cancer.

METHODSForty-two patients with FIGO stage Ib1 approximately Ib2 cervical cancer were selected to receive NSRH (study group, 21 cases) or routine hysterectomy (RH) (control group, 21 cases). Duration of surgery, blood loss and mean length of postoperative stay were compared between the two groups. Immunohistochemical analysis of surgical margins using a general nerve marker (S-100) was performed to compare the nerve damages.

RESULTSThe operation time of NSRH group and RH group was (248 +/- 24) min and (227 +/- 27) min, respectively, with a significant difference between the two groups (P < 0.01). No significant difference in blood loss was found between the NSRH and RH group [(459 +/- 143) ml vs. (454 +/- 121) ml, P > 0.05]. However, the median urinary catheterization time was 7 days in NSRH group versus 16 days in the RH group, with a statistically significant difference between the two groups (P < 0.01). The rate of patients who had postoperative residual urine volume in bladder (PVR) < or =100 ml was 66.7% in the NSRH group versus 19.0% in the RH group, with a significant difference between the two groups (P < 0.01). No severe perioperative complications occurred in both groups. After a follow-up of 11 to 16 months (median: 14 months), no recurrence was detected in the two groups. Immunohistochemistry with S-100 staining revealed only small nerve fibers in the surgical margins of the NSRH group, but full with large nerve bundles in that of the RH group. There was a significant difference between two group (P < 0.01).

CONCLUSIONThe results of our preliminary study indicate that nerve sparing radical hysterectomy (NSRH) for the patients with FIGO stage Ib1 approximately Ib2 cervical cancer is safe and feasible, and can well preserve the pelvic autonomic nerves and improve the recovery of bladder voiding function.

OBJECTIVETo investigate the correlations of serum interleukin-18 (IL-18) level and IL-18 gene promoter polymorphisms to the development of cervical cancer (CC).

METHODSFive single nucleotide polymorphisms (SNPs) of the IL-18 gene promoter region at position rs5744224, rs1946519, rs1946518, rs5744225 and rs5744226 were detected by means of sequences analysis in 50 CC patients and 50 normal subjects that matched for age and residence, and their serum IL-18 level was tested using enzyme-linked immunosorbent assay (ELISA).

RESULTSTwo linkage SNP sites (rs1946519 and rs1946518) in the up-stream of IL-18 gene were identified to present 3 genotypes, namely TT-AA, GG-CC, and TG-AC. A significant difference in the frequency of the 3 genotypes was observed between the CC patients and the normal controls (chi 2=17.497, P=0.000). The frequency of T (A)/G (C) alleles was 42% (42/100) in normal controls and 73% (73/100) in patients, showing significant diference (chi 2=19.662, P=0.000). Serum IL-18 concentrations of the CC patients was significantly lower than that of the normal controls (95.470-/+18.827 vs 116.756-/+16.262 pg/ml, F=14.445, P=0.000). In the cancer patients, serum IL-18 was 90.668-/+20.363 pg/ml for TT-AA genotype, 119.641-/+15.338 pg/ml for GG-CC genotype, and 112.793-/+13.326 pg/ml for TG-AC genotype, showing significant differences (F=11.307, P=0.000). A significant interaction effect was suggested between IL-18 genotype and CC (F=4.223, P=0.018).

CONCLUSIONIL-18 gene polymorphisms and serum IL-18 level are related to the development of CC, and two SNPs, rs1946518 and rs1946519, can be important genetic factors for the susceptibility of cervical neoplasms.

OBJECTIVETo investigate the improvement effects of Jincao tablet on immune function of the model of hysteromyoma in rat and the relationship between the model and pathogenesis.

METHODRats were randomly divided into 6 groups: normal group, model group, treatment groups including low,middle and high dosage groups of Jincao tablet and Guizhi Fuling pill. Rats were injected respectively with diethyl stilbestrol and progesterone. The immune apparatus of rats were measured. The levels of CD3, CD4 and CD4/ CD8 in serum were determined by flow cytometer. The estrogen and receptor were measured by radioligand binding assay and pathologic changes of womb tissue were observed microscopically.

RESULTCompared with normal group, the weight of thymus, the levels of CD3, CD4 and CD4/CD8 of model group were significantly decreased, and the levels of estrogen, estrogen receptor and CD8 were obviously increased. Jincao tablet groups were significant difference compared with model group and could alleviate the pathological changes of womb tissue.

CONCLUSIONJincao tablet could improve the levels of immune function of the model of hysteromyoma in rat, and it might play a role in the pathogenesis of leiomyoma.
