Authors raised that staging based strategies and practice of integrative medicine (IM) by combining syndrome typing and disease identification, and choosing suitable measures in accordance with different persons and seasonal conditions after more than ten years' clinical practice and researches. Radical operation as prior (as evil eliminating) and strengthening vital qi in perioerative period are best strategy for promoting rapid rehabilitation of early stage prostate cancer patients. Strengthening body resistance to eliminate evil was used in treating advanced prostate cancer patients. For example, a comprehensive treatment program for hormone-dependent patients was combined with endocrinotherapy and Chinese herbs for synergisic efficacy-enhancing actions. In this way, these patients' quality of life (QOL) were improved and time to castration resistant prostate cancer (CRPC) was delayed, even some patients were clinically cured. There are lack of effective medicines and methods for CRPC patients. Greatly tonifying original qi is mainly used for improving their clinical symptoms and prolonging survivals. Practice has proved staging based strategies and practice of IM has favorable advantages in treating prostate cancer, especially showing prospect in prolonging survival and postponing progression of advanced prostate cancer patients. Besides, it also could provide beneficial considerations and inspiration for combination of syndrome typing and disease identification.

OBJECTIVETo study the effect of Shenfu Injection (SF) on the apoptosis of prostate cancer PC-3 cells and its possible mechanism.
METHODSWe divided prostate cancer PC-3 cells into a blank control group and three experimental groups, the latter treated with SF at 50, 100, and 200 microl/ml, respectively, for 24, 48, and 72 hours. Then we determined the proliferation of the cells by MTT assay, measured their apoptosis by Annexin V/PI flow cytometry, and detected the expression of P53 mRNA by RT-qPCR.
RESULTSCompared with the blank control group, the survival rates of the prostate cancer PC-3 cells in the 50, 100, and 200 microl/ml SF groups were (93.76 +/- 2.63)%, (81.21 +/- 1.80)% and (18.01 +/- 3.84)% at 24 hours, (94.67 +/-1.11)%, (78.33 +/- 2.89)% and (10.34 +/- 1.44)% at48 hours, and (91.30 +/- 0.47)%, (36.67 +/- 1.56)% and (1.33 +/- 0.32)% at 72 hours, all significantly increased in a dose- and time-dependent manner (P < 0.05). The expression of p53 mRNA was also markedly increased in all the three experimental groups at 48 hours (P < 0. 05).
CONCLUSIONSF can inhibit the proliferation and induce the apoptosis of PC-3 cells, which may due to its upregulation of the p53 mRNA expression.

Objective:
To explore the clinical diagnosis and treatment of seminal vesicle cyst (SVC) associated with ipsilateral renal agenesis (Zinner syndrome) in order to promote the understanding of the disease.
METHODS:
We retrospectively analyzed the clinical data about 1 case ofZinner syndrome diagnosed and treated in our hospital and reviewed the literature related to this disease in domestic and foreign authoritative databases.
RESULTS:
The patient was a 23-year-old male, diagnosed with Zinner syndrome, treated bytransrectal aspiration of SVC, and discharged from hospital 3 days postoperatively. Follow-upat 6 months after discharge found that the patient no longer felt perineal discomfort in the endstage of urination, but transrectal ultrasonography of the prostate revealedthe samevolume of fluid in the left seminal vesicles as before,which indicated recurrence.
CONCLUSIONS
SVC associated with ipsilateral renal agenesis can be considered asZinner syndrome. Transrectal aspiration of SVCcan relieve the local symptoms of the patient but relapse may easilyoccur. Therefore it is not recommended as the first-choice treatment of the disease.

Aim To prepare prostate cancer exosomes containing melittin and observe their uptake by prostate cancer cells. Methods Cells treated with starvation for different time were screened for exosome extraction. Exosomes from PC-3 cells were extracted by ultracentrifugation, and the extracted particles were examined by transmission electron microscopy, nanoparticle tracking analyzer(NTA), and Western blot. Melittin exosome system was prepared by repeated freeze-thaw method, incubation at room temperature as well as electroporation, and the size of encapsulation efficiency was measured by centrifugation. A high-performance liquid chromatography(HPLC)method was applied to assay the content of melittin exosomes(exo-mel). Fluorescence inverted microscopy was employed to evaluate the uptake of melittin exosomes by PC-3 cells, DU145 cells as well as LNCaP cells. Results The results of starvation treatment showed that 24 h starvation treatment was the optimal time point. TEM results showed that the exosomes were round or oval in shape with a distinct membranous structure, and the diameter was around 100 nm. The reagent protein concentration for NTA analysis of exosomes was 0.222 g·L-1. The results of Western blot for the marker proteins of exosomes showed that Alix and CD63 were positively expressed, which indicated that the exosomes could be obtained by starvation culture of PC-3 cells and ultracentrifugation. The results of entrapment efficiency showed that the entrapment efficiency of electroporation method was 17.51% ± 2.39%, that of repeated freeze-thaw method was 11.46% ± 1.02%, and that of room temperature incubation method was 3.93% ± 2.44%. The encapsulation efficiency of electroporation was the highest with significant difference(P<0.05). The uptake assay showed that PC-3 cells could efficiently take up exo-mel in a time-dependent manner, and DU145 cells and LNCaP cells also could take up exo-mel over time. Conclusions Exosomes can be accessed by starvation treatment and high-speed centrifugation, and the prostate cancer melittin exosome system prepared by electroporation method could be taken up by prostate cancer cells.
