Objective:To explore clinical effect of 125I radioactive seed implantation combined with intermittent hormonal therapy (IHT) on prostate cancer. Methods:During the period from May 2016 to May 2017, 84 patients pathologically diagnosed with prostate cancer of T 3N 0M 0 by biopsy in Affiliated Hospital of Chifeng College were enrolled as study objects. They were divided into two groups by random number table method. 40 cases in control group were treated with intermittent hormonal therapy, while 44 cases in observation group were treated with 125I radioactive seed implantation combined with IHT. After the first IHT, time of prostate specific antigen (PSA) returning to normal and intermission time in both groups were observed. The dynamic changes of PSA level and prognosis in both groups during treatment were recorded. Results:After the first IHT, time of PSA returning to normal in observation group was shorter than that in control group, while intermission time was longer than that in control group ( P<0.05). At 3, 6, 12 and 24 months after treatment, PSA level in observation group was lower than that in control group ( P<0.05). The 2-year PSA-free progression survival (PSA-PFS) rate in observation group was higher than those in control group (77.27% vs 45.0%) ( P<0.05). There was no significant difference in 2-year total overall survival (OS) rate between the two groups ( P>0.05). There were no serious complications during treatment in observation group. Conclusions:125I radioactive seed implantation combined with IHT in treatment of prostate cancer can reduce PSA level more quickly, and increase 2-year PSA-PFS rate.

Ginsenosides are the abundant secondary metabolites in American ginseng (Panax quinquefolium), it could be released into soil through root exudation and decomposition during plant growth. This study determined ginsenoside contents in American ginseng cultivated soil by HPLC. Three ginsenosides, Rb1, Rb2 and Rd, were detected in the rhizosphere soil of 3-4 years old American ginseng cultivated in Huairou District, Beijing, and their contents were 0.80-3.19 mg x kg(-1). Correspondingly, the contents of the three ginsenosides in soil solution were 4-16 mg x L(-1) at field water-holding capacity of 20%. According to the field soil test data, we designed the concentration of ginsenosides for bioassays (0.2-125 mg x L(-1) in solution or 0.2-125 mg x kg(-1) in soil). The results showed that radicle lengths of American ginseng were reduced by 6%-23% in solution containing 0.2-125 mg x L(-1) ginsenoside extract, and a significant difference was observed at concentration of 125 mg x L(-1) (P < 0.05). The shoot lengths of American ginseng were not significantly inhibited by 0.2-125 mg x L(-1) ginsenosides extractions. After 20 days of growth in nutrient solution amended with 25 mg x L(-1) ginsenosides extraction, plant height of 3-year-old American ginseng seedling was decreased by 28% compared to the control, and the biomass of aerial parts was also reduced by 50% (P < 0.05). However, the growth of newly-grown fibrous root was not significantly inhibited. Comparatively, when American ginseng embryos were cultivated into sterile or non-sterile soil, neither radicle lengths nor shoot lengths were significantly affected by 0.2-125 mg x kg(-1) ginsenoside extracts. In conclusion, ginsenosides showed autotoxic effect on growth of American ginseng radicle and adult seedling, however, this effect was weakened in field soil.

Background Metadherin is a newly discovered oncogene.It is highly expressed in some solid tumors and plays a significant role in invasion and metastasis of neoplasm as an important biological marker of aggressive cancers.However,there is little data available for the relationship between metadherin expression and clinicopathologic features of retinoblastoma(RB).Objective This study was to investigate the expression of the metadherin in RB cell lines and specimens as well as its clinical significance.Methods The expression of metadherin mRNA in different metastatic potential of RB cell lines(Y79,WERI-RB1 and SO-RB50)was detected by real-time PCR,and the protein expression of metadherin (MDTH)in paraffin-embedded RB tissue was detected by immunohistochemistry.The relevance of metadherin expression to clinical histopathological features was statistically analyzed.Results The relative expression value of metadherin mRNA was 6.11±0.17,6.21±0.21 and 3.97±0.17 in Y79,SORB50,WERI-RB1,respectively,with a significant difference among the three types of cell lines(F =142.643,P＜0.05).The relative expression value of metadherin mRNA was significantly higher in Y79 or SO-RB50 than that in W ERI-RB1 (P=0.000).The expression of MTDH protein mostly located in the cellular membrane and cytoplasm.Among the 54 RB sections,35 (64.81％)showed a high intensity in expression of metadherin protein.The total score of metadherin protein expression was higher in the E stage of RB than that of D stage(P=0.035),in the patients with high-risk factor than those without high-risk factor(P=0.002)and the cases with optic nerve invasion compared to non-invasion (P＝0.017).However,no significant differences were found in the expression of metadherin protein between different ages (P =0.579),different genders (P =0.513),bilateral eyes (P =0.305),different disease courses (P=0.860),various types of differentiation (P =0.537),different degree of the ehoroid invasion (P =0.238),and with or without invasion of the anterior ocular segment (P =0.579).Conclusions Metadherin appears to be highly expressed in RB cells.The activation of the MTDH gene is associated with invasion and metastasis of RB.These results imply that the dynamic change of metadherin expression probably is a prognostic indicator of RB.

Objective To discuss the efficacy of urinary continence in patients undergoing radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis.Methods From August 2016 to November 2018,31 patients with prostate cancer underwent laparoscopic radical prostatectomy.The patients were 62-85 years old(mean 74.8 years),and the mean PSA score was 16.5 ng/ml(6.8-34.2 ng/ml).The pathological examination confirmed that the Gleason score was 6-9 and the prostate size was 44-83 ml.All patients underwent laparoscopic radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis.Surgical procedure:After resection of the prostate in laparoscopic radical prostatectomy,the bladder neck was sutured at 6 o'lock position to narrow the bladder neck (" tennis racquet" reconstruction).The interval was 1 cm,and 2-3 needles were sutured,the distance between the neck of the bladder and the ureter was extended.The bladder neck mucosa and urethral mucosa eversion were performed.The posterior wall of the bladder neck was sutured at interval of 1 cm on both sides of the midline.After the knot was tightened,the posterior wall of the bladder was folded and bladder neck was elevated.The posterior wall of the bladder and the posterior wall of the urethra were sutured to reduce the distance between the bladder and the urethra.Finally,the bladder and urethra were anastomosed.The postoperative urinary continence recovery and the clinical effect were recorded.Results The operation time of 31 patients ranged from 80 to 210,with an average of 139.7 minutes.Intraoperative bleeding was 50-330 ml,with an average of 144.2 ml.None of the patients switched to open surgery during the operation,and there was no injury to large vessels and rectum,and no anastomotic leakage.Postoperative pathology showed 21 cases of pT2 stage,10 cases of pT3 stage,2 cases of positive margin,including 1 case of basal part and 1 case of apex part,both of which received medical castration therapy postoperatively.The surgical margin was positive in 2 cases (6.45％).31 patients removed the urinary catheter in ten days after surgery.17 cases (54.8％) recovered instantly urinary continence;7 cases (22.6％) urinary continence in 1 month after operation;4 cases (12.9％) urinary continence in 3 months after operation;and 3 cases (9.7％) urinary control in 6 months after operation.One case had urinary retention after removing the urinary catheter,and cathetered for 2 more weeks.After pulling out again,the urinary continence was good.Conclusions Laparoscopic radical prostatectomy with bladder neck extension and mucosal eversion reconstruction anastomosis may be helpful for early recovery of urinary continence.

Objective To assess the value of magnetic resonance diffusion weighted imaging(DWI) and apparent diffusion coefficients(ADC) values of hepatic alveolar echinococcosis(HAE) in children.Methods 20 cases of children(≤14 years) with HAE were collected in this restrospective study.PNM staging was determined, the HAE peripheral area of DWI lesions with different P stages was observed, and the ADC value of the peripheral area was measured.The comparison of alveococcus lesions in different stages of DWI with continuous edge degree and ADC value difference was done to evaluate the growth activity.Results There were 5 cases of P1 lesions, 7 cases of P2 lesions, 2 cases of P3 lesions and 6 cases of P4 lesions.DWI features of peripheral area were as follows: High signal ring band between HAE lesion edge and adjacent normal hepatic parenchyma was observed.P1 lesions showed almost complete obviously high signal peripheral area, indicating the most active proliferation, P2 and P3 lesions of peripheral area were continuous and with high signal, and still had obvious growth activity.P4 lesions of peripheral area were not continuous, while the signal decreased, indicating the activity also decreased.The highest ADC value was detected in P1 lesions group of and the ADC value of P2 lesions group were lower than P1, and the ADC value of P4 lesions group were the lowest.P3 lesions samples were too small and thus no statistical analysis was done.Differences of ADC value between the three groups were statistically significant (P<0.05).Conclusion DWI image features could be used to assesse the growth activity of HAE in children with different stages to a certain extent.ADC values measurement provides important reference value for evaluating the growth activity at various stages of the lesions.

Objective To investigate and evaluate the changes of T lymphocytes and red cell immunity of peripheral blood in patients with primary hepatocyte carcinoma (PHCC) after radiofrequency ablation(RFA) treatment. Methods The pre- and post- RFA(3d,7d,14d) peripheral blood T lymphocyte subsets(T3,T4,T8,T4/T8) and red cell immunity (RBC C3 receptor flower and RBC-immuocomplex formation rate) were investigated in 120 patients with PHCC treated by RFA. Results On 7d, 14d after RFA, T3, T4 lymphocytes and T4/T8 were higher than those on preoperative day significantly(P

Objective To assess the clinical efficacy of a modified complete retroperitoneal laparoscopic nephroureterectomy via 3 port approach.Methods From August 2013 to February 2016,23 patients with complete retroperitoneal laparoscopic renal and ureteral sleeve resection were treated with modified three port approach,including 15 males and 8 females.The average age was 67 years old (ranging 44-83 years old).All patients had complained about the hematuria before operation and urine exfoliated cells showed moderate to severe nuclear atypia.All patients accepted the abdominal CT and urography CTU examination,pre-operatively.All of them was diagnosed localized upper urinary tract malignant tumors based on those images,including 13 cases in the pelvis,and 10 cases in the upper segment of the ureter.No chemotherapy,radiotherapy or immunotherapy was performed before surgery.No patients have the history of severe basic disease or upper urinary procedure.The operations were performed under general anesthesia,patients take the contralateral back 30 degrees slope,low elevation head foot,waist bridge,side waist stretch.In the anterior superior iliac spine perpendicular to the line 2 cm parallel to the lower intersection of the rib border were disposed into the 12 mm trocar.Above the anterior superior iliac spine two cross finger level with the intersection of the anterior axillary node,we placed into the 10 mm trocar placement lens.Laparoscopic placement of third casing form an isosceles triangle with the first two casing.The renal fascia was incised with an ultrasonic knife from the renal dorsal side,and the renal hilum was isolated from the kidney by suction aspirator.The renal artery and vein were separated and closed by hem-o-lok.Along the psoas muscle surface to ureter,ureteral clipping by hem-o-lok but not to cut off the free distal ureteral,the lens is composed of first casing into,using ultrasonic knife to free ureter to the bladder wall segment,with 30 mm endoscopic stapler ureter and bladder wall cut off part.Operation time,blood loss and postoperative recovery were recorded in 23 cases.Results All 23 cases were successfully operated without related the operative complication.The operative duration ranged from 3.5 to 6.1 h (mean 4.8 h),the blood loss was 30-880 ml (mean 304 ml),and the postoperative stay was 8-30 d (mean 17.8 d).There are 3 cases of positive lymph node by postoperative pathological reports.Within 2 to 30 months following up,2 patients died of tumor progression in 6 months after surgery.4 patients were diagnosed with bladder cancer in 15 months,15 months,21 months,24 months after surgery,respectively.And the transurethral resection of bladder tumor was performed.Conclusion The modified complete retroperitoneal laparoscopic nephroureterectomy via three ports is safe and reliable.

BackgroundOsteopontin is highly expressed in many metastatic tumors,but its expression in uveal melanoma and the relationship of osteopontin with metastasis is still under investigation.Objective This study was to investigate the relationship between osteopontin expression and uveal melanoma metastatic potential.Methods Fifty samples of uveal melanoma were collected in Beijing Tongren Hospital.The expressions of osteopontin in the samples were detected using immunohistochemistry,and expressions of osteopontin mRNA in different metastatic potential uveal melanoma cell lines (MU M-2B,C918,OCM-1A) were analyzed using quantitative polymerase chain reaction (Q-PCR).ResultsOsteopontin was positively expressed in 10 samples of 13 patients with metastasis and 14 samples of 37 patients without metastasis,showing a significant difference between them (x2=5.888,P=0.000).There were 11 samples and 13 samples exhibiting the positive expression of osteopontin in 15 epithelial type and 35 non-epithelial type of uveal melanoma respectively with the significant difference (x2=5.510,P =0.000).The positive expressing numbers of osteopontin were 20 tumors of 30 affected tumors and 4 tumors of 20unaffected ciliary tumors with the significant difference (x2 =10.470,P =0.000 ).No significant differences in the expression of osteopontige were found between different gender,age,eyes,largest basal diameters and invasion of scleral canal( P =0.536,0.256,0.802,0.848,0.555 ).The relative expression value of osteopontin mRNA was in turn 1.00±0.04,0.91 ±0.03,0.08±0.01 in MUM-2B,C918,OCM-1A with the significant difference among three cell lines( F=33.135,P＜0.05).The osteopontige mRNA expression was significant enhanced in high metastatic potentialcell lines( MUM-2B,C918 ) compared with low metastatic potential cell lines( OCM-1 A) (P＜0.05 ),but no significant difference was seen between two high metastatic potential cell lines(MUM-2B,C918) (P=0.804).Conclusions Osteopontige expression is associated with the uveal melanoma cell line invasion and metastasis potential.These results imply that osteopontige expression maybe an indicator of uveal melanoma invasion and metastasis ability.
