Small-cell carcinoma of the prostate: A report of 2 cases and review of the literature / 中华男科学杂志

Objective@#To investigate the clinicopathological characteristics and improve the clinical treatment of prostatic small-cell carcinoma (PSCC).@*METHODS@#We reported 2 cases of PSCC derived from prostate cancer after treated by androgen blockade and prostate electrotomy and reviewed the relevant literature.@*RESULTS@#Two patients with PSA elevation were diagnosed with prostate cancer by prostatic puncture biopsy and treated by maximum androgen blockade, which reduced their total PSA to the normal level. Later, due to difficult urination, they both underwent prostate electrotomy, followed by chemotherapy or radiotherapy for PSCC confirmed by postoperative pathology. Nevertheless, they died at 8 to 9 months after the discovery of PSCC.@*CONCLUSIONS@#PSCC can derive from prostate cancer after treatment, which may be attributed to the pathological mutation induced by long-term endocrine therapy. PSCC is more malignant than prostate cancer, and its prognosis is poor.

Zinner syndrome:A case report and review of the literature / 中华男科学杂志

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.

Staging Based Strategies and Practice for Prostate Cancer / 中国中西医结合杂志

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.

Shenfu injection induces the apoptosis of prostate cancer PC-3 cells / 中华男科学杂志

<p><b>OBJECTIVE</b>To study the effect of Shenfu Injection (SF) on the apoptosis of prostate cancer PC-3 cells and its possible mechanism.</p><p><b>METHODS</b>We 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.</p><p><b>RESULTS</b>Compared 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).</p><p><b>CONCLUSION</b>SF can inhibit the proliferation and induce the apoptosis of PC-3 cells, which may due to its upregulation of the p53 mRNA expression.</p>
