Objective To investigate the clinical characteristics and treatment method of pulmonary metastasis of transitional cell carcinoma of urinary tract.Methods The clinical data of 18 patients with pulmonary metastasis of transitional cell carcinoma of the urinary tract,who were admitted to the Second Hospital of Tianjin Medical University from July 2005 to March 2009 were analyzed.Results The primary sites of transitional cell carcinoma of these 18 patients were renal pelvis(8 cases),ureter(6 cases) and bladder(4 cases).Multiple metastases to both lungs were found in 14 cases,the chest X-ray showed dense nodular shadows in different size diffused in both lungs,and CT examination revealed the same picture.All the 14 patients were treated with systemic chemotherapy,and 13 of them underwent surgical operation after the discovery of local recurrence in their bladders.Isolated lung metastasis was found in 4 cases,in whom chest X-ray showed isolated dense nodular shadow in the lung,and CT examination revealed soft tissue shadows adjacent to the chest wall.All the 4 patients were treated with implantation of radioactive pellets and systemic chemotherapy,and one of them underwent surgical operation after the discovery of a local recurrence in the bladder.Follow-up was conducted for 6-36 months.Two patients died in 6-12 months,14 died in 12-24 months,and 2 survived for longer than 24 months.Conclusions The incidence of pulmonary metastasis of transitional cell carcinoma of urinary tract is low.Chest radiograph and CT are the main diagnostic means.Systemic chemotherapy should be used as the main treatment for diffuse pulmonary metastasis,radioactive pellet implantation and systemic chemotherapy should be used for a localized isolated pulmonary metastasis,and surgical operation should be done for the patient with local recurrence in the bladder.

Objective To determine common molecular markers between endometriosis and ovarian cancer . Methods The specimens from 31 endometriosis patients who underwent laparoscopic excision , 28 other disease patients with normal oarium and 35 ovarian cancer patients who received the ovariectomy were collected. Expressions of transforming growth factor β1 (TGF-β1), cyclooxygenase 2 (COX-2), vascular endothelial growth factor (VEGF), estrogen receptor 1α(ER-1α), progesterone receptor (PR), androgen receptor (AR) and aromatase (CYP19) were detected by real-time reverse transcription polymerase chain reaction (RT-PCR). Results Compared with those in normal oarium group, the mRNA levels of TGF-β1, VEGF, ER-1α, AR, CYP19 and COX-2 in endometriosis group were increased by 2.05 fold, 2.20 fold, 3.32 fold, 1 . 45 fold , 3 . 19 fold and 3 . 00 fold , respectively , and the mRNA level of PR was reduced by 69 % ( all P< 0.05), while those in ovarian cancer group were increased by 5.61 fold, 7.61 fold, 7.49 fold, 4.79 fold, 7.76 fold and 5.35 fold, respectively, and the mRNA level of PR was reduced by 95 % (all P< 0.05). Conclusion In endometriosis and ovarian cancer tissues, the expression levels of TGF-β1, COX-2, VEGF, ER-1α, AR and CYP19 are increased, and the expression levels of PR are decreased, which maybe suggest both diseases are potentially relevant.

Objective To investigate the diagnostic value of acridine orange fluorescene(AO-F) in bladder cancers. Methods One thousand and sixteen bladder cancer patients were reviewed retro-spectively. The positive-rates of AO-F in different stages, grades, size, quantity, position of tumors, hematuria and treatment ways were evaluated. Results The total positive rate of AO-F was 78.05 % (793/1016). The positive-rate was 74.69% (611/818) in superficial stage and 91.92% (182/198) in invasive bladder cancer, 67.24% (351/522) in grade Ⅰ and Ⅱ , 90. 37% (413/457) in grade Ⅲ. The percentage of positive AO-F was 80.30% (750/934) in patients with hematuria, 52.44% (43/82) in patients without hematuria. The percentage was 79.87% (710/889) when the tumor size was more than 2 cm, 65.35% (83/127) when size less than 2 cm. 83.07% (363/437) sample was positive in multiple tumors, 74.27% (430/579) in single tumor. The percentage was 77.21% (105/136) in tumors involving trigone or neck of bladder, 78.07% (687/880) in tumors without involving these re-gions. There was 69.68% (393/564) in treatment with TURBt, 87.87% (268/305) in partial resec-tion, 91.74% (100/109) in total resection. A good association was observed between stage, grade, hematuria appearance, tumor size, quantity of carcinoma, treatment way and AO-F positive-rate, and a linear correlation was present between grade, stage and positive cytology. There was no significant association between position of the tumor and AO-F positive-rate. Conclusions The function of AO-F is significant in diagnosis of bladder cancer.

Objective To study the effect of PIM-1 gene silence by RNA interference (RNAi) on the growth of human prostate cancer xenograft tumor in nude mice. Methods The xenograft tumor model of human prostate cancer was established by injecting PC-3 cells in armpits of 12 nude mice. After modeling, the nude mice were randomly divided into three groups: interference plasmid group (injecting with RNAi recombinant plasmid), empty plasmid group and negative control group (liposome every), 4 mice in each group. Mice were injected every 2 days for 5 times. The tumor volumes of xenografts were measured during experiment, and the curve of tumor growth was drawn accordingly. The quality of tumor was measured, and the inhibitory rate of tumor was calculated at the end of the experiments. The expression levels of PIM-1, c-MYC mRNA and protein in xenograft tumors were detected by real-time PCR and Western blot assay, respectively. Furthermore, immunohistochemistry staining was used to verify the expression of PIM-1. Results The xenograft tumor model of human prostate cancer was established successfully. The volume of tumor was significantly decreased 6 days after the injection treatment in interference plasmid group than that of empty plasmid group and negative control group. The effect of suppressing tumor growth was remarkable. The expression levels of PIM-1 mRNA and protein were down-regulated significantly in interference plasmid group than those of other two groups. The immunohistochemical staining of PIM-1 showed the same changes. There was no significant difference in c-MYC protein level between the three groups. But interestingly, the c-MYC mRNA level was significantly decreased in interference plasmid group than that of other two groups. Conclusion The silence of PIM-1 gene by RNAi recombinant plasmid can result a significant growth suppression of the human prostate cancer xenograft tumors in nude mice. The expression of c-MYC gene is down-regulated at translation level in the therapeutic group concomitantly. PIM-1 may be a promising target of gene therapy for prostate cancer.

OBJECTIVETo systematically evaluate prostate health index (PHI) in predicting the results of prostate biopsy in the diagnosis of prostate cancer.

METHODSWe retrieved the literature relevant to the value of PHI in predicting prostate cancer at prostate biopsy published from the inception to February 2014 in the databanks of PubMed (1966 - 2014), CNKI (1982 - 2014), VIP (1989 - 2014), and Cochrane Library (1999 - 2014). According to the inclusion and exclusion criteria and retrieval strategies, we extracted the data, evaluated the quality of the included literature, and performed meta-analysis using the Meta-Disc 1.4 software.

RESULTSTotally, 64 articles were identified, of which 52 were excluded and 12 included with 1 430 cases of prostate cancer and 2 159 normal or BPH controls. There was heterogeneity among the included studies. Based on the random effect model, in predicting the results of prostate biopsy in the diagnosis of prostate cancer, serum PHI exhibited a pooled sensitivity of 55.1% (95% CI: 0.525 - 0.577), a pooled specificity of 71.5% (95% CI: 0.695 - 0.734), a positive likelihood ratio (P-LR) of 2.379 (95% CI: 1.922 - 2.943), a negative likelihood ratio (N-LR) of 0.515 (95% CI: 0.428 - 0.619), a diagnosis odds ratio (DOR) of 5.268 (95% CI: 3.870 - 7.170), a summary receiver operating characteristic curve--area under the curve (SROC AUC) of 0.7578, and a Q * index of 0.6999.

CONCLUSIONSerum PHI plays a role of auxiliary diagnosis in detecting prostate cancer and can be used in the prediction of the results of prostate biopsy.

BACKGROUND:The number of elderly patients with hip fracture is huge, and this population mainly combines with a variety of internal diseases. The general condition was bad. Compared to total hip arthroplasty, bipolar hemiarthroplasty can shorten operation time, reduce the time of anesthesia and improve surgical safety, but the operation using which fixation mode is always controversial.
OBJECTIVE:To compare the safety and curative effects of bipolar hemiarthroplasty with cementless or cement femoral stem prosthesis in elderly patients with osteoporotic complex hip fracture.
METHODS:From June 2007 to June 2010, 198 elderly patients with osteoporotic hip fracture aged more than 75 years old, who were treated with bipolar hemiarthroplasty in the People’s Hospital of Xinjiang Uygur Autonomous Region, China, were enroled in this study. Al patients were divided into cementless group (n=69) and cement group (n=129) according to the type of prognosis. Osteoporosis was treated conventionaly in both groups after replacement. Operation time, intraoperative blood loss, incidence of postoperative hip pain, out of bed activity time post surgery, Harris scores of last folow-up and loosening rate of the prognosis were compared between the two groups.
RESULTS AND CONCLUSION:176 of above 198 cases were folowed up for 48 to 84 months, including 122 in the cement group and 54 in the cementless group. Operation time was longer in the cement group than in the cementless group, but out of bed time was earlier in the cement group than in the cementless group post surgery, and there were significant differences (P < 0.05). The incidences of loosening and hip pain were more in the cement group than in the cementless group post surgery (P < 0.05). No significant difference in intraoperative blood loss and Harris scores of last folow-up was detected between the two groups (P > 0.05). The incidences of loosening rate were 5% and 4% in the cement and cementless groups, respectively, which showed significant differences (P< 0.05). These results indicate that bipolar hemiarthroplasty with or without cement for osteoporotic hip fracture in the elderly can obtain good middle- and long-term effects. Bipolar hemiarthroplasty with cement can reduce the out of bed time, but operation time was longer, and incidences of hip pain and loosening were higher in cement prosthesis than in cementless prosthesis.
