Objective To investigate the incidence of renal dysfunction among patients received radical nephrectomy during 5-year follow-up and to discover the risk factors for chronic kidney dysfunction (CKD).Methods Data of 339 patients who underwent radical nephrectomy for renal cell carcinoma between Jan.2006 to Dec.2007 were investigated,and those who suffered renal dysfuntion before surgery or lost follow-up were excluded.Finally,148 patients were enrolled in this retrospective study.GFR after surgery were replaced by eGFR which were calculated with the abbreviated equation of MDRD.It will be defined as CKD when eGFR was less than 60 ml/(min · 1.73 m2).Postoperative occurence rate of CKD was estimated using the Kaplan-Meier methods.Rank sum test and chi-square test were used for the univariate analysis in term of CKD between groups.Multivariate Logistic regression analysis was used to judge the independent risk factors for CKD.Results Patients were followed up for 42-60 months.CKD occurred in 58 cases,and the 5 year cumulative incidence of CKD was 42.7％.As many as 17.4％ of the patients with a normal eGFR during the first 3 months follow-up would progress to CKD 5 years later.Clinical characteristics,including age at surgery,weight,body mass index,hypertension,preoperative total GFR and contralateral GFR,complications,size of tumor,pathologic type,eGFR calculated shortly after operation,were significantly different between the CKD group and the normal group (P＜0.05).Multivariate Logistic regression analysis shows that age at surgery (P =0.016,OR =1.106),size of tumor (P =0.048,OR =0.680) and eGFR calculated within one week postoperatively (P=0.002,OR=0.874) were the independent risk factors for postoperative CKD.Conclusions The incidence of CKD after radical nephrectomy in patients with renal cell carcinoma is not uncommon.The of age at surgery,size of tumor and eGFR value calculated within one week postroperatively have a close relation with the incidence of postoperative CKD.

ObjectiveTo investigate the effect of radiation therapy for extracerebral large paracavernous sinus cavernoma.Methods8 cases with extracerebral large paracavernous sinus cavernomas treated with routine fractionated irradiation therapy alone were analyzed retrospectively with 1～4 year follow-up. ResultsThe volume of the tumor in all eight cases decreased in some degree, with ratio of 28.8% to 54.5%, after radiation therapy. ConclusionFor the extracerebral large cavernoma hard to excision, radiation therapy can decrease the tumor volume so that to wait for operation.

Objective To investigate the relationship between chronic prostatitis (CP) and male infertility. Methods 120 cases of male infertility patients with chronic prostatitis and 120 cases of male infertility patients with-out chronic prostatitis were analyzed. Results The differences of sperm quality、sperm movement function, partial bio-chemical indicator in semen and sperm aggregation in the two groups are significant (P<0.05). Conclusion CP plays an important negative role in male infertility.

Objective To investigate the creatinine level of wound drainage and the changes of serum creatinine after radical nephrectomy or partial nephrectomy in patients with renal cell carcinoma,to explore the feasibility of testing creatinine level to predict urine leakage after surgery and to compare the influence on rcnal function after different kinds of operations.Methods 65 patients data were analyzed,in which 31 patients had undergone partial nephrectomy and 34 had radical nephrectomy for renal cell carcinoma from March 2012 to July 2012.The level of creatinine in serum and wound drainage were detected within 24 hours after surgery.Also,the serum creatinine were redetected 3 months later.Results The creatinine level of wound drainage were significantly lower than that in serum in both groups [(99.94±21.10) μmol/L vs (114.61± 25.09) μmol/L,P =0.000].Urine leakage was observed in only one patient (2.9 ％) after partial nephrectomy,which his level of creatinine in serum and wound drainage was 107 μmol/L and 686μmol/L,respectively.The other 30 patients' creatinine level of wound drainage were also significantly lower than serum after partial nephrectomy [(92.90±26.21) μmol/L vs (99.83±28.77) μmol/L,P =0.021).Although the level of creatinine in the wound drainage was not significantly different between these two groups (P =0.239),the serum creatinine was statistical lower in partial nephrectomy group than that of radical nephrectomy group (P =0.035).Also,after three months,the partial nephrectomy group had a lower level of serum creatinine [(81.43±12.82) μmol/L vs (106.53±21.73) μmol/1,P =0.001].Conclusion Partial nephrectomy has advantages in protecting renal function when compared with radical nephrectomy.The level of creatinine in wound drainage is significantly lower than serum.The level of creatinine in wound drainage is a predictive indicator for diagnosing urine leakage.

OBJECTIVETo assess the clinical effectiveness of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius.

METHODSAccording to Cochrane Systematic Review, Medline, Embase, Cochrane Li- brary, CNKI and CBM, randomised controlled trials (RCTs) of volar and radial column approach by plate fixation for the treat- ment of unstable fracture of distal radius were searched for from 1966 to 2014. Data analysis was performed with the Cochrane Collaboration's RevMan 5.0 software.

RESULTSTotally 391 patients of 6 RCTs and 2 retrospective cohort studys were included and divided into volar plate group (187 cases) and radial column plate group (204 cases). Meta-analysis result showed: compared with radial column plate group, volar plate group had significant difference in recovery of wrist function [SMD = 0.74, 95% CI (0.47, 1.01), P < 0.00001], Gartland-Werley scores [SMD = -1.39, 95% CI (-2.24, -0.53), P = 0.001], postoperative neural in- jury [OR = 3.67, 95% CI (1.37, 9.84), P = 0.01 1 and postoperative wrist pain [OR = 0.32, 95% CI (0.13, 0.74), P = 0.008]. But no significant difference was identified in DASH scores [SMD = -0.36, 95% CI (-0.97, 0.26), P = 0.25], radiographic result assess- ment [SMD = -0.18, 95% CI (-0.53, 0.16), P = 0.3], postoperative grip strength [SMD = 0.71, 95% CI (-0.12, 1.54),P = 0.09], postoperative tendinous damage [OR = 0.31, 95% CI (0.10, 0.98), P = 0.05] and carpal tunnel syndrome [OR = 0.96, 95% CI (0.63, 1.48), P = 0.87].

CONCLUSIONCompared with radial column plate internal fixation, volar approach plate fixation for treat- ment of distal radius intra-articular fracture has advantage of recovery of joint functionand. However, the volar approach plate fix- ation was associated with a higher risk of long-term complications than the radial column approach plate fixation.

Objective To investigate the effect and mechanism of transplantation of marrow multi- function stem ceils in treating femoral head necrosis.Methods Sixty japanese rabbits were divided into A,B and C groups randomly.After creation of the models of hormone induced necrosis of femoral head;A group was designated as the treatment,B as the control and C as the normal groups.The bone marrow of A group was extracted and isolated and then injected into the left femoral head and the right femoral head was decompressed by drilling only.The rabbits were killed at 8 weeks after the treatment and changes in various parameters were observed,including imaging data of molybdenum target films,CT and MRI;routine pathology with HE staining and ultrastructural alteration by election microscopy.Results Eight weeks after the treatment of transplantation of marrow multifunction stem cells,the X-ray showed only a little change but the typical appearances were revealed by CT and MRI.Pathohistologic manifestation demonstrated decrease of empty bone lacuna,increase of osteoblast and new bone formation.Election microscopy displayed abundant organelles in osteoblasts with few empty bone lacuna,in addition the tansplantation of marrow multifunction stem cells could obtain better reconstraction for the involved femoral head.Conclusions The treatment of transplantation of marrow muhifunction stem cells in femoral head necrosis could accelerate the process of repairing,worthy to be acknowledged as a good and valuable management in rabbits.(J Intervent Radial,2007,16:122-126)

In this paper, the number of rhizosphere and non-rhizosphere microbial organisms of fusarium wilt resistant and susceptible watermelon under soil culture and soilless substrate culture was studied by traditional culture methods. The results showed that, the number of rhizoshpere microorganisms was significantly higher than non-rhizosphere, and the number was changed with the stage of watermelon grow, the number was the lowest in seedling stage and increased with the watermelon grow, and achieved highest at the flowering and fruiting stage, decreased with the watermelon ageing. The fusarium wilt resistant of watermelon was correspondence with number of rhizosphere bacteria; the number of rhizosphere bacteria of resistant watermelon was higher than that of susceptible watermelon in each stage under soil culture and soilless culture. The fusarium wilt resistant of watermelon is no correspondence with number of rhizosphere fungi and actinomycete. The number of non-rhizosphere microbial organisms was changed in a small range in the whole growing stage. The non-rhizosphere bacteria have no significant change in the whole stage under soil culture and increased quickly under soilless substrate culture and decreased at the later stage. The non-rhizosphere fungi and actinomycete reached highest at the later stage under soil culture or soilless sub-strate culture.
