1.The research progress of repeat prostate biopsy
Chinese Journal of Urology 2021;42(1):71-74
Repeat prostate biopsy is of great significance for missed diagnosis of prostate cancer. We make a review on the independent risk factors, route selection and new techniques to improve clinicans’ cognition of prostate biopsy indications. MpMRI targeted biopsy is recommended for patients who are eligibile for repeat biopsy for higher detection rate of clinically significant prostate cancer and lower rate of non-clinically significant prostate cancer.

Objective To evaluate the different effects of the treatment of thoracolumbar fractures by pedicle of vertebral arch Tenor system and Harrington device.Methods The clinical data of 35 cases of thoracolumbar fractures were analyzed retrospectively, 23 of them were operated with Harrington device and 12 with Tenor system.Results These cases were followed up for 6 months to 2 years. The fractures treated with Tenor system got satisfied reduction, reached about 96 7% of normal vertebral height. The deformities were completely corrected and complications were significant lower than those derived from Harrington device treatment, and no delayed neurologic damage was found. Most cases got reduction with one to three Frankel grades of neurologic recovery.Conclusion The Tenor pedicle system is more effective in treatment of thoracolumbar fracture than non-pedicle device. It can get satisfied fracture reduction , reliable fixation and less complications.

The 1,095 bp gene encoding peroxidase from Coprinus cinereus was synthesized and integrated into the genome of Pichia pastoris with a highly inducible alcohol oxidase. The recombinant CiP (rCiP) fused with the a-mating factor per-pro leader sequence derived from Saccharomyces cerevisiae was secreted into the culture medium and identified as the target protein by mass spectrometry, confirming that a C. cinereus peroxidase (CiP) was successfully expressed in P. pastoris. The endoplasmic reticulum oxidoreductase 1 (Ero1) and protein disulfide isomerase (PDI) were co-expressed with rCiP separately and simultaneously. Compared with the wild type, overexpression of PDI and Erol-PDI increaseed Cip activity in 2.43 and 2.6 fold and their activity reached 316 U/mL and 340 U/mL respectively. The strains co-expressed with Erol-PDI was used to high density fermentation, and their activity reached 3,379 U/mL, which was higher than previously reported of 1,200 U/mL.

Objective:To investigate the existence of side population cells with the potency of stem cells in human gallbladder carcinoma cell line GBC-SD and the differences in ABCG2,Oct-4 and CD34 expression among SP cells,non-SP cells and GBC-SD cells.Methods:SP and non-SP cells were sorted from GBC-SD cells by fluorescence-activated cell sorting(FACS).The expression of ABCG2,Oct-4 and CD34 in SP cells,non-SP cells,and GBC-SD cells was detected by reverse transcription-polymerase chain reaction(RT-PCR),Western blot,flow cytometry(FCM)and immunofluorescence chemistry.Results:SP cells with stem cell potency were isolated from GBC-SD cells with a proportion of(0.64±0.08)%.The metastatic ability of SP cells was obviously higher than that of non-SP cells and GBC-SD cells(P<0.05).The expression of ABCG2 was significantly higher in SP cells than in non-SP cells and GBC-SD cells[(89.56±3.86)%vs.(1.32±0.49)%and(12.37±1.61)%,P=0.001].The expression of Oct-4 in these cells was(94.87±1.40)%,(88.16±2.34)%and(90.17±1.61)%,respectively(P>0.05).CD34 was neady absent in these cells on protein level[(1.78±0.51)%vs.(0.63±0.21)%and(0.96±0.381)%,P>0.05)],but it was highly expressed in non-SP cells and GBC-SD cells and absent in SP cells off mRNA leve;.Conclusion:SP calls which hava the potency of stem cells,exist in human gallbladder carcinoma GBC-SD cell line and have the phenotype of ABCG2+Oct-4+CD34-.

ObjectiveTo evaluate the clinical effects of surgery using scar flap in situ combined with radiotherapy in 24 hours in the restorative treatment of keloids on the auricula and the preventive effects of the therapy in the recurrence of the keloids.MethodsThe scar flap in situ was designed,its size was large enough for covering the wound of the keloid on the auricula.The keloids along the designed lines were excised using local anesthesia,the flap was clipped into the one with even thickness and suitable size which covered the wound tensionlessly to ensure that the scar flap in situ survived well,and then the wound was bandaged with pressure and drained when necessary.18-24 hours after the surgery the wound was perpendicularly irradiated by the 5 MeV high energy electron beam (beta particle) of the Siemens Primus linear accelerator.After the dressing change was performed and the drain was removed; the wound was exposed to the irradiation,3-4 Gy segmentation dose per time,and the wound was then bandaged with pressure.The radiation was performed every two days and four times altogether with a total irradiation dose of 12-16 Gy.Stitches were removed 8-10 days after the surgery.ResultsThere were no avascular necrosis in the 25 scar flaps in situ and the wounds were all primary healing with normal color and fine appearance.All the patients were satisfied with the surgery.There was no recurrence of the 23 patients during the 8 to 42 months' follow-up,but there was a tendency to recur in 2 patients after 4-6 months,and the recurrence was controlled after the beta methasone was locally injected for 2-4 times.ConclusionsIt is not necessary to harvest the flaps on the other sites applying the sear flap in situ in the restorative treatment of keloids on the auricula,and therefore it prevents the formation of the keloids on the donor sites.Furthermore,the surgery is simple and the appearance of the auricula is fine,and it presents satisfactory clinical effects to irradiate the wound in 24 hours after the surgery.

Objective To explore the association between the genetic polymorphism of CYP3A4,CYP2D6 and response to methadone maintenance treatment(MMT)among heroin-dependent patients.Methods Patients undergoing MMT in 6 MMT clinics were randomly selected,information about general socia-demographic characteristics,drug abuse history,and MMT data of patients were collected,genotypes of peripheral blood CYP3A4 and CYP2D6 polymorphic loci were detected.Results A total of 820 patients were enrolled in the study,210 cases were with good response and 610 cases with poor response to MMT.Difference in age between different response groups was statistically significant(P<0.05).Distribution of genotype frequency and allele frequency of CYP3A4 rs2242480 and CYP2D6 rs16947 between good response and poor response groups was not significantly different(both P>0.05).Conclusion The association between CYP3A4 rs2242480,CYP2D6 rs16947 and response to MMT has not yet found in heroin-dependent patients.
