Chinese Journal of Urology 2014;35(9):672-675
Objective To compare clinical efficacy and complications of three operation methods for treating the localized and high risk prostate cancer.Methods From July 2006 to July 2010,102 cases with localized and high risk prostate cancer were included in the study.Among them,51 cases received open radical prostatectomy (Group A).Their characters included aged (63.7±7.9),PSA (31.8±6.6) μg/L,Gleason scores (8.5±0.5).In this group,T2c stage was diagnosed in 38 cases and T3a stage in 13 cases.32 cases received laparoscopic radical prostatectomy(Group B).Their characters included aged (64.4± 8.3),PSA (29.9±5.2) μg/L,Glcason scores (8.7±0.4).In this group,T2c stage was diagnosed in 21 cases and T3a stage in 11 cases.19 cases received 125I implantation (Group C).Their characters included aged (61.4± 7.4),PSA (30.6±.5.7)μg/L,Gleason scores (8.6±0.6).T2v stage was found in 8 cases and T3a stage in 11 cases.Operation time,amount of bleeding,hospitalization time,drainage time,gastrointestinal function recovery time,medical expenses and survival and recurrence rate in 1 year,3 years,5 years were compared within those groups.Results Operation time in three group were (232.6±38.4) min,(186.3±31.4) min,(35.4±14.6) min,respectively.Amount of bleeding in three group were (413.6±132.4) ml,(273.9± 77.4) ml,(19.4±4.4) ml,respectively.Hospitalization time in three group were (20.9±3.7) d,(15.6± 2.2) d,(6.4±2.6) d respectively.Drainage time in three group were (8.3±1.8) d,(7.5±0.9) d,(3.2± 0.8) d,respectively.Gastrointestinal function recovery time in three group were (4.1 ±0.6) d,(3.2± 0.4) d,(0.4±0.1) d,respectively.Medical expenses in three group were (23±4) thousand yuan,(32±3) thousand yuan,(45t3) thousand yuan respectively.All those items exhibited the significantly statistical difference (P<0.05).The survival and recurrence rates had no significant difference during the follow-up in three groups.Conciusions Compared to the open radical prostectomy and laparoscopic radical prostectomy,particle implantation for prostate cancer had advantages in minimally invasive,less bleeding,short operation time,fast recovery and protection for Intestinal function.

Objective To study the absorption and transportation of flavonoids in Herb Epimedii by using Caco-2 monolayer model. Methods Caco-2 cell monolayer model was used to study the bi-direction transport of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ. The concentration of the five flavonoids in cell culture medium was measured by UPLC and the apparent permeability coefficients (Papp) were calculated. Results The absorptive permeability coefficients (PAB) of icariin, epimedin A, epimedin B, epimedin C, and baohuoside Ⅰ were 5.91?10-7, 3.22?10-7, 2.76?10-7, 4.23?10-7, and 1.46?10-6 cm/s, respectively. Except baohuoside Ⅰ, the other four flavonodes had lower permeabilities, and the secretive permeabilities (PBA) of all the flavonoids were larger than their absorptive permeabilities. Among them, the PBA of baohuoside Ⅰ was 9.8 times as much as the PAB. Conclusion The results suggest that the intestinal absorption of the five flavonoids is lower, which might have efflux mechanism by transporters, and the absorption of monloglycoside (e.g. baohuoside Ⅰ) is better than that of diglycoside (e.g. icariin) and triglycoside (e.g. epimedin A, epimedin B, and epimedin C).

OBJECTIVE:To study the effects of modern decoction method vs. traditional decoction method on decoction rate and decoction quality. METHODS: The advantages and disadvantages were compared between the two decoction methods through analysis on the whole decoction process and the storage of the decoction before oral administration taking major components or active components as parameters. RESULTS: As compare with traditional decoction method, the modern decoction method had more advantages for in which the operation is standard, the contents of active components were high, and the quality control can be performed from many ways. CONCLUSION: The modern decoction method deserves to be popularized.
6.Experience of diagnosis and treatment of iatrogenic injury by ureteroscopic surgery
Chinese Journal of Urology 2013;34(12):921-923
Objective To summarize the experience of diagnosis and treatment of iatrogenic injury by ureteroscopic surgery.Methods Retrospective analysis of 13 cases with iatrogenic injury by ureteroscopy from December 2008 to December 2011,including 8 men and 3 women,aged 15 to 75 years.Among the 13 cases (Holmium laser lithotripsy under ureteroscope),there were 5 cases of ureterostoma severe disruption,4 cases of submucosa injury,2 cases of perforation,1 case of disruption,and 1 case of sleeve exfoliation of mucosa.Results Among these 13 cases with iatrogenic injury by ureteroscopy,10 cases underwent double J drainage (drainage duration:60 days),and 3 cases underwent open surgery immediately.There was no hydronephrosis when examined by IVU after six months to two years follow-up.Conclusions The skills and techniques of surgical operation should be improved when performing ureteroscopic operation,and it is essential to be familiar with ureteric dissection and alignment,which can avoid ureteric injury.Indwelling D-J tube is very important in dealing with mild ureteral injury secondary to ureteroscopes.Surgical intervention should be given to severe cases of ureteric injury in time.

Objective To investigate the influence of intraoperative posture intervention on drainage in patients after gynecological laparoscopic surgery. Methods A total of 1250 patients who were scheduled for gynecological laparoscopic surgery including laparoscopic-assisted salpingoplasty,oophorocystectomy,ectopic pregnancy,vaginal hysterectomy,myomectomy and appendectomy were randomly divided into two groups. The patients' posture was changed from Trendelenburg position to level lithotomic position during suction by the circulating nurses in the experimental group,while after surgery in the control group. The volume and time of drainage,and the length of stay after surgery were compared between the two groups. Results The volume and time of drainage,as well as the length of stay after surgery had significant differences between the two groups (P<0.05). Conclusions Intraoperative posture intervention is helpful for the treatment effect of drainage after gynecological laparoscopic surgery.

10.A comparative study between conventional and endoscope-assisted greater saphenous vein harvesting
Journal of Interventional Radiology 2004;0(S2):-
Objective To compare between conventional and endoscope-assisted greater saphenous vein harvesting and to invest if endoscope-assisted greater saphenous vein harvesting can reduce post-operative leg incision complications.Methods Minimally invasive endoscopic saphenous vein harsvesting technique has been used in 36 isolated CABG patients and this is compaired with 50 conventional saphenous vein harsvesting group. There is no significant difference in sex structure, age, hypertension, diabetes mellitum (DM), myocardial infarction (MI) et al in two groups. Results The incidence of post-operative leg complications with minimally invasive greater saphenous vein harvesting group (2.8% ) was remarkably lower than that in conventional group (28%), and the hospital-stay time was much shorter in minimally invasive group. Conclusion Endoscope-assisted saphenous vein harvesting is a effective method in reducing post-operative leg incision complications.
