The clinical data of 21 cases of adrenal ganglioneuroma treated in our hospital from July 1988 to August 2008 were reviewed. The clinical manifestations were: lower back uncomfortableness (9 cases), paroxysmal dizziness (4 cases), central obesity ( 1 case) and 7 cases were discovered incidentally.Five cases were diagnosed pre-operationally and remaining 16 cases were diagnosed post-operationally by pathology. All patients completely recovered after surgery except one, who still had dizziness with high blood pressure. Ultrasonography, CT and MRI examinations are the main diagnostic methods for adrenal ganglioneuroma, and it is confirmed by histopathology, surgical removal of the tumor is the main therapy for the disease.

Two hundred and five patients with a confirmed diagnosis of aldosterone-producing adenomas underwent retroperitoneal laparoscopic operation from January 1999 to December 2009 in our hospital. All cases had hypokalemia and hypertension preoperatively. Of all the cases, 80 received total adrenalectomy and 125 received partial adrenalectomy. Operations were successfully performed in all cases. The time of operation ranged from 15 to 150 min [mean(45 ±13) min] and the volume of bleeding during operation ranged from 10 to 200 ml [mean(25 ±10) ml]. The length of hospital stay ranged from 4 to 9 d [mean(6. 8 ± 1. 2) d]. All patients were followed up for 0. 5 - 2 years (mean 1. 2 years). After operations blood potassium levels returned to normal in all cases, blood pressure returned to normal in 168 cases (82.0% ) . Results indicated that partial or total adrenalectomy with retroperitoneal laparoscopy for aldosterone-producing adenomas was safe and feasible technique.

7. Diagnosis value of multiparametric magnetic resonance imaging for prostate cancer
Academic Journal of Second Military Medical University 2017;38(2):212-219
Prostate cancer is the most common malignant tumor in men of western countries and its incidence is increasing in China. However, the traditional methods of screening and diagnosing of prostate cancer are of limited value. Multiparametric magnetic resonance imaging (MRI) is an examination which combines morphologic sequences with one or more functional sequences. Multiparametric MRI can not only display the anatomical structures and morphologic changes of organs, but also reflect some histological components, providing pathophysiological and biochemical information of tissues and guiding prostate targeted biopsy at the same time. These advantages give multiparametric MRI high application value in the diagnosis and evaluation of prostate diseases. This review summarized the recent progress in multiparametric MRI diagnosis of prostate cancer.
8. PRDM5 gene can inhibit the growth of prostate cancer cell line 22Rv1
Academic Journal of Second Military Medical University 2016;37(6):724-728
Objective To investigate the antitumor effect of PRDM5 gene in prostate cancer cells. Methods PRDM5 gene was cloned and inserted into lentiviral vector using polymerase chain reaction (PCR), restriction endonuclease and T4 DNA ligase connected method. The lentiviral plasmids carrying PRDM5 gene (LV-PRDM5) or control lentivirus (LV-Luc) were co-transfected with lentiviral packaging plasmid mix into 293T cells by liposome method. The viral supernatants were collected and transduced into human prostate cancer cells 22Rv1. The expression of PRDM5 was verified by Western blotting analysis. The cell proliferation and clone formation ability were detected by cell multiplication and cell cloning experiments. The anchorage independent growth rate of prostate cancer cells was assessed by soft agar colony formation assay. Results The lentivirus vector expressing PRDM5 gene was constructed successfully, and the viral supernatants were obtained. The prostate cancer cell line 22Rv1 stably expressing exogenous PRDM5 was screened and verified by Western blotting analysis. Compared with control cells, the prostate cancer cell line 22Rv1 expressing PRDM5 showed a lower growth rate (multiplication time: [52.5±1.4] vs [44.0±1.3] h), clone formation rate ([1 114±98] vs [1 361±123] colonies per dish) and anchorage independent growth rate ([94.6±8.7] vs [154.0±3.5] colonies per cell, P<0.05). Conclusion Overexpression of PRDM5 has inhibitory effect against proliferation, clone formation and anchorage independent growth of prostate cancer cells in vitro.
9. Transcatheter closure of unilateral renal artery with a newly-developed double waist occluder in dogs
Academic Journal of Second Military Medical University 2016;37(6):767-770
Objective To evaluate the safety and efficacy of transcatheter closure of renal artery with a newly-developed double waist occluder in dogs. Methods A newly-developed double waist occluder was implanted in the right renal arteries of 12 healthy dogs. The location of devices was observed by angiography immediately, and 1, 3 and 6 months after occlusion. Renal specimens and occluders was observed after the animals were sacrificed and pathological examination was conducted. Also the endothelialization on the surface of the occluders was observed. Results Transcatheter closure of unilateral renal artery was successfully performed in all the 12 dogs. One dog died due to overdose of narcotic drugs, and the other 11 dogs survived well. Complete occlusion of the renal artery was achieved in 6 dogs immediately after the occluder was implanted, and complete occlusion was seen in all the dogs within 12 min after occlusion, with all the devices in good position and without translocation. Repeated angiography showed in all animals that the occluders were in good position and without residual shunt. The occluded kidneys became smaller than the opposite ones, with the surface of occluded kidney turning lumpy and hard. Endocardial cells started to cover the surface of occluder 1 month after closure and complete coverage was seen 3 months later. Conclusion The newly-developed double waist occluder is safe, feasible and effective, and it can be delivered in small sheath owning to its excellent trafficability.
10. Laparoscopic partial nephrectomy via combined “trans-retro-peritoneal three-step” approach: An initial experience
Academic Journal of Second Military Medical University 2016;37(1):83-86
Objective To evaluate the safety and efficacy of laparoscopic partial nephrectomy via a combined "trans-retro-peritoneal three-step" approach. Methods The clinical data of 32 patients who received laparoscopic partial nephrectomy between Jul. 2015 and Nov. 2015 were retrospectively analyzed. Twenty cases were via the traditional transperitoneal approach and the other 12 cases via a novel combined "trans-retro-peritoneal three-step" approach. The 3 steps in this novel approach included: (1) Through transperitoneal approach, Gerota's fascia and perirenal fat were incised to expose the tumor; (2) The peritoneum and Gerota's fascia were incised along the Told's line, and the renal artery was then separated on the surface of the psoas muscle; and (3) The renal artery was clamped, the edge of the tumor was marked, and finally the tumor was resected and the kidney was reconstructed. The perioperative data of the two groups were compared. Results The surgeries were successfully performed in all the 32 patients. Compared to traditional transperitoneal approach, our novel approach significantly shortened the operation time (P=0.014). The other perioperative parameters, such as estimated blood loss, were comparable in the two groups. Conclusion This combined "trans-retro-peritoneal three-step" approach has the combined the advantage of traditional transperitoneal (enough room for manipulation) and retroperitoneal (convenience to separate the renal arteries) approaches, especially when the renal artery is abnormal. Further studies are needed to compare the present approach with the traditional surgeries.
