Objective To investigate the correlation between ultrasonographie classification, age and lesion in female. Methods One thousand two hundred and eight patients with 2416 mammary gland were comfired by pathologic findings, including 132 benign lesion and 54 malignancy lesion. According various sonographic appearances in the mammary gland structure and involution grade, the mammary glonds were classified into glandular,fibroglandular and fatty types. A single mammary gland is statistic unit. Results To follow age growth, the proportion of glandular type was decrease, 61.7% in under 30 years of age,31.5% in 30-39 years of age,15.3% in 40-49 years of age,8.6% in 50-59 years of age,4.5 in over 60 years of age. To follow age growth, the proportion of fatty type was higher, 1.6 % in under 30 years of age, 5.80% in 30-39 years of age,5.5% in 40-49 years of age,10.8% in 50-59 years of age,38.6% in over 60 years of age. Before 60 years of age, to follow age growth, the proportion of fibroglandular type was higher, which achieved the peak value (79.2%) in 40-49 years and last to 50-59 years of age (80.6%) ,but it was decrease to 56.9% after 60 years of age. There was significant difference of the proportion in any age(P=0.000).The proportion of the benign lesion no difference in three categories. The proportion of malignancy lesion (6.23%, 16/257 mammary gland)in fatty type was higher than that in fibroglandular type (2.18%,37/1698 mammary gland) which was significant difference(P=0.000). There was no malignancy lesion in glandular type. Conclusions Significant correlation were present between uhrasonographic classification, age and malignancy lesion, no significant correlation were found between uhrasonographic classification, age and benign lesion.

Objective To investigate the diagnosis and treatment of cystic renal cell carcinoma.Methods The clinical data of 67 cases of cystic renal cell carcinoma treated from January 2005 to April 2013 were analyzed retrospectively.Preoperative imaging procedures indicated masses of renal cysts in 67 cases,including malignant tumors in 59 cases.Intraoperative pathological examination was performed in 59 cases and the pathological results showed malignant tumors in 56 cases,renal cyst in 2 cases and multilocular cyst of kidney in 1 case.The surgical procedures included radical nephrectomy (n=19),partial nephrectomy (n =12),retroperitoneal laparoscopic radical nephrectomy (n =9),retroperitoneal laparoscopic partial nephrectomy (n =20),retroperitoneal laparoscopic cyst unroofed then transferred to radical nephrectomy (n =6),and retroperitoneal laparoscopic partial nephrectomy transferred to radical nephrectomy (n =1).Results The 67 cases were diagnosed as renal carcinoma,including clear renal cell carcinoma with cystic changes in 31 cases and multilocular renal cell carcinoma in 36 cases.Sixty-two cases were followed up for 10-110 months (median 56 months),and there was no recurrence or metastasis,among which 7 cases diagnosed as benign pre-operation or intra-operation but malignant by pathological examination after surgery were followed up for 61-103 months (median 82 months).Conclusions Imaging plays an important role in the early diagnosis of cystic renal cell carcinoma.Intraoperative pathological examination should be performed in suspected cases.Nephron-sparing surgery is preferred with good outcome.

Objective To compare the complete ablation rate of radiofrequency (RF) ablation and high-intensity focused ultrasound (HIFU) in the treatment of uterine ifbroids with different blood supply. Methods One hundred and ten patients with 146 uterine ifbroids in Xijing Hospital of the Fourth Military Medical University from January 2009 to December were randomly divided into two groups and treated with HIFU or RF respectively. Each group had 55 patients. All patients were examined by color Doppler lfow imaging before the treatment. The blood supply of ifbroids were semi-quantitatively classiifed into three grades including G1, G2 and G3. The HIFU group had 15 patients with 20 ifbroids in which blood supply was G1, had 32 patients with 38 ifbroids in which blood supply was G2, and had 8 patients with 10 ifbroids in which blood supply was G3. The RF group had 14 patients with 18 ifbroids in which blood supply was G1, had 31 patients with 42 ifbroids in which blood supply was G2, and had 10 patients with 18 ifbroids in which blood supply was G3. The complete ablation rates of the two treatments were evaluated by contrast-enhanced ultrasound one week before and after treatments. Fibroids which had no contrast agent perfusion and smooth boundary were completely ablated. Statistical analyses were used to compare the complete ablation rates and postoperative complications rates of these two methods. Results When ifbroid′s blood supply was G1, the complete ablation rate was 80.0%(16/20) and 88.9%(16/18) in HIFU and RF group, respectively. The difference was not statistically signiifcant (χ2=0.563, P>0.05). When ifbroid′s blood supply was G2 and G3, the complete ablation rate in HIFU and RF group was 90.5%(38/42) vs 55.3%(21/38) and 72.2% (13/18) vs 20.0% (2/10), respectively. There was statistically difference between these two groups (χ2 =12.778, P < 0.05;χ2=7.049, P < 0.05, respectively). Postoperative complications included fever, abdominal pain, pelvic effusion and vaginal discharge and unilateral lower limb numbness. The incidence of complications was lower in HIFU group than that in RF group, which was 9.1%(5/55) and 27.3%(15/55) respectively, This difference was statistically signiifcant (χ2=6.111, P<0.05). Conclusions HIFU and RF are both effective in treating uterine ifbroids with few blood supply. However, RF can be more effective than HIFU in treating hypervascular ifbroids. Therefore, RF might be able to apply to majority of the ifbroids. As a non-invasive therapy, HIFU is more suitable for hypovascular ifbroids and could be the ifrst therapy in clinic.

OBJECTIVETo study the value of multislice spiral computed tomography (CT) in the diagnosis of ovarian fibroma.

METHODThe CT findings of 9 cases with pathologically confirmed ovarian fibroma were retrospectively analyzed by two radiologists.

RESULTSAll of the 9 cases showed unilateral adnexal mass with demarcated boundary. There were three different types of ovarian fibroma according to the CT appearances simple type(n=4), degeneration type(n=3) and the ovarian fibroma with ascites(n=2). The simple type showed homogeneous-density solid tumor with no enhancement; two of them diagnosed as uterine leiomyomas and the other two as benign tumor originated from the ovary. The degeneration type showed irregular or round hypodensity inside the tumor with no enhancement; one of them was diagnosed as malignant tumor and the other two as intrapelvic mass. The ovarian fibroma with ascites showed homogeneous density with no enhancement; one with ascites and pelvic effusion and the other one with pleural effusion, ascites and pelvic effusion, both of whom were diagnosed as malignant tumor that possibly originated from the ovary.

CONCLUSIONSThe ovarian fibroma has diverse CT findings. They often appear as a unilateral adnexal solid tumor without obvious enhancement. A diagnosis of Meigs's syndrome may be made when it is accompanied with ascites and pleural effusion.

OBJECTIVETo explore the methylation status in promoter region of norepinephrine transporter gene (NET, SLC6A2) in heart failure ( HF) patients and its correlation with qi deficiency/blood stasis syndrome (QDS/BSS).

METHODSThirty-six patients with heart failure (NYHA classification III to IV) were recruited in the study (as the heart failure group) and their scores of QDS/BSS were evaluated. Besides, a healthy elderly group (30 cases) and a healthy youth group (30 cases) were also set up. They were recruited from Physical Examination Center of Fujian Provincial Hospital. Pyrosequencing was applied to detect the methylation in promoter region of SLC6A2 gene, and the total methylation index (MTI) of CpG island was calculated. The correlation between the methylation status in promoter region of SLC6A2 and scores of QDS/BSS was assessed using Pearson and Partial analyses. Risk factors were screened and adjusted using Logistic regression.

RESULTSBy one-factor analysis of variance, the total MTI in the HF group (219.72% ± 54.03%) was obviously higher than that in the healthy elderly group (194.47% ± 34.92%) and the healthy youth group (161.60% ± 41.11%) (all P < 0.05). Meanwhile, the total MTI was higher in the healthy elderly group than in the healthy youth group (P < 0.01). By covariance analysis , after controlling age and BMI, the total MTI was higher in the HF group than in the healthy elderly group (P = 0.041), while it was higher in the healthy elderly group than in the healthy youth group (P = 0.016). Age was found to play an essential role in affecting MTI of SLC6A2 gene promoter region among the 3 groups (F = 16.447, P = 0.01). The total MTI was quite lower in the healthy youth group. Results of Partial correlation analysis showed MTI was positively correlated with scores of qi deficiency and blood stasis respectively (r = 0.494 and 0.419 respectively, both P < 0.05). Logistic regression analysis showed after adjusting confounding factors, the relative risk (OR value) of total MTI of SLC6A2 gene in promoter region was 1.038 (95% CI, 1.006 to 1.071, P = 0.020).

CONCLUSIONSAbnormally elevated methylation of the promoter region of SLC6A2 gene is one of risk factors for HF. In addition, the degree of methylation of the promoter region of SLC6A2 gene was positively correlated with the severity of QDS/BSS.

Purpose To explore the effects of estrogen receptor antagonist on the expression of estrogen receptor subtype (ERα, ERβ), and p57kip2 protein in human endometrioid carcinoma cells named JEC. Methods The JEC cells (moderately differentiated EC cells) cultured in vitro were treated with β-Estradiol (E2) (10～6 mol/L) and two types of estrogen receptor antagonists, tamoxifen (TAM) and fulvestrant (ICI182780) (10-6 mol/L). After 24, 48, 72 h, MTT was used to detect the growth condition of JEC cells, and the light microscopy and electron microscopy were used to observe the growth condition and morphological changes of cells, Western blot was used to detect the expression of ERα, ERβ, PR-A, PR-B and P57kip2 protein in JEC cells. Results MTT results: Compared with the control group, E2 could promote the proliferation of JEC cells significantly (P＜0.05), and ICI182780 could inhibit the proliferation of JEC cells obviously (P＜0.05). Compared with the E2 group, the proliferation ability of JEC cells in E2 + ICI182780 group were lower(P＜0.05). Morphological change: Compared with the control group, the cells density of E2 group increased obviously, and the pathologic mitosis was easy to seen in some cells. The cells density decreased obviously in ICI182780 group. Compared with E2 group, the cells density of E2 + TAM group and E2 + ICI182780 group were decreased, and pathological mitotic figures were difficult to seen. Western blot results: Compared with the control group, the expression of ERβ protein increased, and the expression of p57kip2 protein decreased in E2 group (P＜0.05). The expression of ERβ protein decreased, and the expression of p57kip2 protein increased in ICI182780 group and TAM group, and the difference was statistically significant between ICI182780 group and control group (P＜0.05). Compared with the E2 group, the expression of ERβ protein decreased, and the expression of p57kip2 protein increased in E2 + ICI182780 group and E2 + TAM group, and the difference was statistically significant between E2 + ICI182780 group and E2 group (P＜0.05). ERa protein of JEC cells did not expressed in experimental group or control group. Conclusion ERa protein are not expressed in JEC cells. ICI182780 have a stronger role in antagonizing estrogen, and may induce the expression of p57kip2 protein by down-regulating the expression of ERβ protein in JEC cells, block the cell cycle progression and inhibit the growth of tumor cells. TAM has a weaker estrogen like effect on the growth of JEC cells. It is possible that combined detection of the expression of ERa and p57kip2 protein in EC has an important reference value for individualized selection of endocrine therapy for EC patients.

OBJECTIVETo investigate the effects of interferon -alpha1b (IFN-alpha1b) on hepatic intercellular adhesion molecule-1 (ICAM-1) expression and serum HBV DNA in patients with chronic hepatitis B.

METHODSBefore and 6 months after IFN-alpha1b treatment, liver biopsy was performed in patients with chronic hepatitis B to detect the expression of ICAM-1 in the liver tissues using immunohistochemistry. Serum HBV load was detected with real-time fluorescence polymerase chain reaction.

RESULTCAM-1 expression in the liver tissue was significantly down-regulated after IFN treatment in patients with severe and moderate chronic hepatitis B (P<0.05). No significant variation was noted in the expression of ICAM-1 in the livers of patients with mild chronic hepatitis B after the treatment (P>0.05). In the patients weakly positive for ICAM-1 expression (+), serum HBV DNA varied scarcely after the treatment (P>0.05), while in the patients with strong ICAM-1 positivity (++, +++, or ++++), significant variation of serum HBV DNA occurred after the treatment (P<0.05 or P<0.01).

CONCLUSIONThe therapeutic effect of IFN-alpha1b is associated with the expression of ICAM-1 in the hepatocytes, and its expression might enhance the effects of IFN on HBV DNA in patients with chronic hepatitis B.

OBJECTIVETo explore the diagnosis, treatment, and prognosis of prostatic malignant mesenchymal tumors (PMMT).

METHODSWe retrospectively analyzed the clinical and follow-up data about 20 cases of PMMT and reviewed the literature relevant to the diagnosis, treatment, and prognosis of the disease.

RESULTSBased on the results of pathology and immunohistochemistry, the 20 PMMT cases included leiomyosarcoma (n = 7), rhabdomyosarcoma (n = 5), prostatic stromal sarcoma (n = 3), chondrosarcoma (n = 1), and undifferentiated PMMT (n = 4). Twelve of the patients were treated by radical prostatectomy (3 concurrently by sigmoid colostomy and 1 by cystostomy), 2 by pelvic tumor resection following arterial embolization, 1 by total pelvic exenteration, 1 by colostomy with pelvic lymph node biopsy, and 4 by conservative therapy because of metastasis to the lung, pelvis and bone. Of the 20 patients, 9 died of systemic metastasis within 3 months after treatment, 3 died at 6, 7, and 14 months, respectively, 3 survived with tumor for 5, 11, and 12 months, respectively, 2 survived without tumor for 12 and 24 months so far, all subjected to periodic chemotherapy postoperatively, and 3 lost to follow-up.

CONCLUSIONPMMT is a tumor of high malignancy and rapid progression, for which transrectal ultrasound-guided biopsy remains the main diagnostic method. The clinical stage of the tumor is an important factor influencing its prognosis and the survival rate of the patients can be improved by early diagnosis and combined therapy dominated by radical prostatectomy.

OBJECTIVETo investigate the correlation between nonalcoholic fatty liver disease (NAFLD) and three anthropometric indices, namely waist to hip ratio (WHR), body mass index (BMI) and waist to height ratio (WHtR).

METHODSThis retrospective case-control study involved 77 NAFLD patients and 50 patients without such disease, and their data of the 3 anthropometric indices were collected. Risk correlation analysis and Mantel-Haenszel chi-square test were used for correlation analysis.

RESULTSNAFLD was significantly correlated to WHR (chi(2)(MH)=59.609, P<0.001; odds ratio=30.522, 95% CI 12.815-72.695), WHtR (chi(2)(MH)=45.316, P<0.001; odds ratio=21.037, 95% CI 8.665-51.072) and showed a dose-response relationship with BMI (chi(2)=25.017, P<0.001).

CONCLUSIONThese results support a close correlation between NAFLD and the 3 anthropometric indices, indicating that BMI, WHR and WHtR can be significant predictors of NAFLD and have potential value for evaluating and predicting NAFLD.
