Objective To investigate the radiobiological effects of VPA-BSANPs on C6 and U87 glioma cells in vitro.Methods C6 and U87 glioma cells were treated with different concentrations of VPA and VPA-BSANPs for 12 h and 24 h,and MTT assay was used to determine cell viability.C6 and U87 cells were treated with different concentrations of VPA and VPA-BSANPs conbined with X-ray irradiation (0,2,4,6,and 8 Gy),and colony formation assay was used to determine plating efficiency (PE).C6 and U87 glioma cells were treated with different concentrations of VPA and VPA-BSANPs for 12 h,followed by X-ray irradiation (0,4,and 8 Gy),and flow cytometry using Annexin V-FITC/PI staining was used to examine cell apoptosis.Western blot was used to evaluate the effects of VPA and VPA-BSANPs on radiation-induced apoptosis protein expression.One-way ANOVA was used for comparison of means with homogeneity of variance between multiple groups,and the t-test was used for comparison of means between two groups.Results Without irradiation,VPA and VPA-BSANPs had no significant inhibitory effects on the proliferation of C6 and U87 cells (P=0.328,0.920).The PE of cells treated with VPA-BSANPs combined with irradiation was significantly lower than that of cells treated with VPA combined with irradiation (P=0.000).In C6 and U87 cells,VPA-BSANPs combined with irradiation increased the expression of p53 and Bax (P =0.000,0.000 and P =0.010,0.002),but reduced the expression of Bcl-2 (P =0.008,0.000).Active caspase-3 fragments were only found in the cells treated with VPA-BSANPs combined with irradiation and VPA combined with irradiation,but were less in the former cells than in the latter cells (P=0.004).The active fragments of peroxisome proliferator-activated receptor were only found in the cells treated with VPA-BSANPs combined with irradiation.Conclusions VPA-BSANPs can increase the radiosensitivity of C6 and U87 glioma cells in vitro,possibly by promoting the apoptosis of tumor cells induced by radiation.

Objective To study the bowel-cleansing efficacy, patient security and mucosal injury of low-volume PEG plus ascorbic acid regimen. Methods Five hundred patients referred for colonoscopy were enrolled and randomly divided into two groups. Group A received low-volume PEG regimen, Group B received sodium phosphate (NaP) regimen for bowel preparation. Patients of the two groups drank solution 5 h before colonoscopies, serum creatinine and electrolyte were monitored at 5 h and 3 h before colonoscopies. The bowel-cleansing efficacy was rated during colonoscopy. All mucosal injuries observed during colonoscopy were biopsied and histopathologically reviewed. Results The patients of group A completed bowel preparation of 233 cases, completed colonoscopy 226 Cases, group B completed bowel preparation 238 cases, completed colonoscopy 210 cases. There was no significant difference in bowel cleansing between the groups (P > 0.05). Group A reported less incidence rate of the mucosal injuries than Group B. Group A reported better patient security than Group B at the same time. Conclusion Compared with sodium phosphate (NaP) regimen low-volume Polyethylene Glycol (PEG) plus ascorbic acid regimen exhibited equivalent bowel-cleansing efficacy and less incidence rate of the mucosal injuries and better patient security.

Objective To investigate the value of B7-H3 in expressed prostatic secretions (EPS) in differential diagnosis of patients with inflammatory elevation of PSA in t-PSA gray zone (4-10 ng/ml). Methods One hundred and sixteen patients from the ages of 19 to 80 years (mean, 40 years) were stu-died. In the group there were 91 chronic prostatitis (CP) patients (mean age 31 years, 19-49 years), including 11 chronic bacterial prostatitis (type II) patients, 26 inflammatory nonbacterial prostatitis (IIIA) patients and 54 noninflammatory nonbacterial prostatitis (IIIB) patients. Transrectal ultrsound guided prostate biopsy was performed on 25 patients (mean age 71 years, 62-80 years) with t-PSA in gray zone (7.21±2.60 ng/ml). Five had positive results, Gleason score was 6 in two cases, 7 in two cases and 8 in one case. Twenty patients had negative results, of whom 11 patients had inflammatory cell infiltration. EPS was collected by transrectal massage, and Enzyme-linked immunosorbent assays (ELISA) were performed for B7-H3 detection. In addition, 11 normal male controls with a mean age of 30 years (24-46 years) were recruited into the study. Volunteers were excluded if they had a history of genitourinary symptoms or surgery.Results The EPS B7-H3 levels of controls, II, IIIA, IIIB groups were 49.81±11.54, 19.33±13.90, 17.67±15.76, 25.14±13.44 ng/ml, respectively. The levels of EPS B7-H3 in positive biopsy, noninflammatory negative biopsy and inflammatory negative biopsy groups were 26.30±16.32, 30.23±18.42, 10.11±5.42 ng/ml, respectively. The highest levels were found in the control group (P<0.01). Compared to the IIIB, B7-H3 levels in II and IIIA groups were significantly lower (P<0.05). There was no significantly difference between II and IIIA groups (P>0.05). The EPS B7-H3 levels in the inflammatory negative biopsy group were statistically lower than in positive biopsy and noninflammatory biopsy groups (P<0.05). But no significant differences were found among inflammatory negative biopsy, II and IIIA groups (P>0.05). Receiver operating curve (AUC=0.883, P=0.001) utilizing EPS B7-H3 levels≤16.24 ng/ml identified patients with inflammatory elevation of PSA with a sensitivity of 78.6% and a specificity of 81.8% from patients with t-PSA in gray zone. Conclusion The EPS B7-H3 detection provides a new way for differential diagnosis of patients with inflammatory elevation of PSA in t-PSA gray zone resulting in a reduction of unnecessary prostate biopsy.

Objective To evaluate the effect of transurethral feedback microwave thermotherapy with the ProstaLund CoreTherm Device(PLFT) in high risk patients with benign prostate hyperplasia (BPH). Methods Sixty-six high risk patients diagnosed with BPH, including aged ≥80 in 32 pa-tients, hypertension in 31 patients, diabetes in 5 patients, heart failure in 8 patients, chronic obstruc-tive pulmonary disease in 8 patients, cerebral infarction in 11 patients, fracture, amputation or joint stiffness unsuitable for lithotomy position in 3 patients, abnormal blood coagulation in 4 patients, pan-creatitis in 2 patients, cardiac arrhythmia in 6 patients and malignant tumor in 3 patients, were treated with PLFT using individual power at urethral local anesthesia, resulting in coagulation necrosis in 15%-30% of prostate tissue around urethra. Meanwhile, real-time monitoring the temperature of prostate and the tissue around it was used. All patients were evaluated by comparing volume of pros-tate, maximal urinary flow (Q_max), international prostate symptom score (IPSS) and quality of life questionnaire (QOL) in pre-treatment and three months after respectively. Results All of patients well tolerated PLFT. There was bleeding lightly, infection lightly and temporary incontinence. There was no severe surgical complication. After three months, the volume of prostate reduced from 62. 2 ml to 44.5 ml; IPSS decreased from 23. 4 to 11.7; QOL decreased from 4.5 to 2.4; Q_max rised from 4, 2 ml/s to 11.2 ml/s. All differences reached significance. Conclusion PLFT is one of effective and safe treatments for patients with BPH especial BPH complicating with severe conditions.

Objective To investigate the approach and safety of minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi. Methods Clinical data of 21 cases with symptomatic caliceal diverticular calculi were retrospectively reviewed. Twelve females and 9 males aged 22 to 57 years old. The average diameter of caliceal diverticulum was 3.7 cm (2.5-7.0 cm) and average diameter of calculi was 2.3 cm (0.8-3.5 cm). The patients underwent flexible ureteroscopic lithotripsy, PCNL or mPCNL, laparoscopic techniques and laparoscopy-assisted transperitoneal PCNL, respectively. Four cases underwent flexible ureteroscopic lithotripsy. PCNL (2 cases) or mPCNL(5 cases)were performed in 7 cases. Nine cases underwent laparoscopic techniques. Laparoscopyassisted transperitoneal PCNL was performed in 1 case. Results The operations were performed successfully in 21 cases. No case need to transfer to open surgery during the operation and no major complications like perforation or organic injury were noted. One case with iatrogenic arteriovenous fistula of the kidney after 1 week postoperative was cured by delayed hemorrhage 2 days later, while clinical symptoms of 2 cases with residue calculi relieved. 19 cases without residue calculi were followed up for 6 to 12 month without recurrence. Conclusions After handling indication of treatment efficiently and creating advisable therapeutic decision-making, minimally invasive surgical procedures treating symptomatic caliceal diverticular calculi appears to be effective and safe.
