Ojective To study the probability of laparoscopic adrenalectomy in the treatment of adrenal benign tumor. Methods Laparoscopic adrenalectomy were used to treat pheochromocytoma and primary aldosteronism. Results Average operation time was 200 min and average bleeding was 110 ml. The patients began to walk two days after operation. Hyperension and low blood potassium level syndrom disappeared gradually. Conclusions Laparoscopic Adrenalectomy has the advantage of minimal invasion, faster recover from operation, shorter hospitolized days and higher quarlity of life after operation for the patients.

Objective To evaluate the treatment of ureteral stones with pneumatic lithotripter under ureterscopy and the prevention of complications. Methords 43 cases of ureteral stones that had been treated with pneumatic lithotripter under ureteroscopy was reviewed. Results 93.0%(40/43)of the stones were fragmented on one session,93.0%(40/43)of the stones were expelled within 7 days afer the procedure.No complications occurred. Conclusions Treatment of ureteral stones with pneumatic lithotripter under ureterscopy is safe and effecive.

Objective To explore the therapeutic efficacy of pneumatic lithotripsy combined with extracorporeal shock wave lithotripsy (ESWL) in patients with ureteral stones. Methods Pneumatic lithotripsy combined with ESWL was employed in the treatment of 365 cases of ureteral stones. Results Of the 365 cases,the operation succeeded in 360 cases and failed in 2 cases,and ureteral perforation occurred in 3 cases.ESWL was required in 80 cases after pneumatic lithotripsy. Conclusions Pneumatic lithotripsy combined with ESWL offers advantages of high efficacy,minimal invasion and broad indications.

The most common metastatic site of prostate cancer is the bone, followed by the lung, bladder, liver, and adrenal gland. We report on a rare case of pancreatic metastasis from prostate cancer. A 52-year-old patient was admitted to the hospital with epigastric pain for 20 days. PET-CT showed malignant lesions in the prostate and pancreas, and prostate and pancreas puncture biopsies were performed, respectively. The patient was diagnosed as prostate cancer with pancreatic metastasis according to the pathological findings. After undergoing androgen deprivation therapy and docetaxel chemotherapy for 6 cycles, reexamination revealed that the pancreatic metastases had disappeared.

BACKGROUND:The effects of advanced glycation end products (AGEs) on osteoclast-induced bone resorption is controversial and the underlying mechanisms remain unclear. Most of the studies indicate that AGEs can enhance bone resorption, while some othersshowthe opposite effects.
OBJECTIVE:To investigate the effects of AGEs on osteoclast-induced inorganicmatrixdissolution and organic componentdegradation and the underlying mechanisms.
METHODS:RAW 264.7 cels were induced to generate osteoclasts,and AGEs (50-400 μg/mL) or control-bovine serum albumin (100 μg/mL) was added since the beginning of the induction. The effect of AGEs on bone resorption was evaluated by analyzing the area of resorption pits on the Osteo Assay Surface plates and the expression of cathepsin K. Furthermore, the number of tartrate-resistant acid phosphatase (TRAP)-positive multinucleated cels, nuclei per osteoclasts and the expression of integrinανβ3were detected.
RESULTS AND CONCLUSION:The area of resorption pits and expression of cathepsin K in AGEs groups were significantly decreased compared withthecontrol group, and this inhibiting effect became more obvious with the increase of AGEs concentration. TRAP staining also showed that number of TRAP-positivemultinucleated celsand nuclei per osteoclast were significantly reduced in an AGE dose-dependent manner. Quantitative PCR revealed that the expression of integrin ανβ3decreased significantly with the extension of AGEs incubation time. These data indicate that AGEs can exert inhibitory effects on organic and inorganicmatrixdegradation induced by osteoclasts. The underlying mechanism may be involved in the inhibitory effects of AGEs on directed differentiation and cel fusion of osteoclast precursor cels, and migration and adhension of osteoclasts.

Objective To review the experience of the clinical diagnosis and treatment of primary testicular diffuse large B-cell lymphoma.Methods A review was made who were treated in the Tumor Hospital of Zhengzhou University from January 2011 to November 2018.The average age of the patients was 58 years old,with 4 cases in left side and 8 cases in right side.All patients were admitted to hospital with painless testicle mass.Solid mass of testis were detected by ultrasound with no abnormality in tumor markers.All patients underwent orchiectomy and followed by chemotherapy.Results Twelve primary testicular lymphoma (PTL) were identified by pathology,with 8 cases in phase Ⅰ,2 cases in phase Ⅱ,1 case in phase Ⅲ,and 1 case in phase Ⅳ.The mean follow-up was 31 months.Inguinal orchiectomy was recommended as a diagnositc and initial therapy.All patients underwent R-CHOP/CHOP chemotherapy consisting of cyclophosphamide,doxorubicin,vincristine and prednisone with or without rituximab,including 6 cases with R-CHOP and 6 cases with CHOP.Nine of 12 patients underwent intrathecal prophylatic chemotherapy and 6 of 12 patients underwent contralateral testicle radiotherapy.Relapse occured in 2 patient with CHOP in central nervous system and died of the disease.One case with CHOP relapsed in abdominal cavity.No contralateral testicle relapse was observed.Conclusions PTL is a rare extranodal lymphoma.Painless testicle tumor in men over 50 years old should suspect of this disease.Inguinal orchiectomy is an important part of the treatment,which combines systemic chemotherapy and prophylactic modalities such as radiotherapy of contralateral testis and/or central nervous system (CNS) prophylaxis.

Objective: To summarize the clinical experience of primary bladder lymphoma. Methods: From September 2012 to May 2019, 8 cases of primary bladder lymphoma treated in our institute were analyzed retrospectively, including 4 males and 4 females. The mean age was 50.5 years old, ranged from 15 to 85. There were 3 cases of localized bladder lymphoma and 5 cases of metastatic bladder lymphoma. Three cases presented with painless gross hematuria primarily and 5 cases suffered from abdominal pain and bloating. Imaging examination showed the bladder tumor or pelvic mass with maximum diameter ranged from 3 to 22 cm, with 11.3 cm on average. Preoperative diagnosis of bladder tumor in 3 cases, and pelvic malignant tumor in 5 cases. Two patients underwent TURBT and 6 cases underwent pelvic mass resection and partial cystectomy. Results: Postoperative pathological diagnosis showed 6 cases of diffuse large B-cell lymphoma, 1 case of mucosa-associated lymphoid tissue lymphoma, 1 case of anaplastic large cell lymphoma. Follow-up after surgery ranged 3 to 60 months, with 28.1 months on average. Two patients can not tolerate radiotherapy or chemotherapy for postoperative complications of vesico-vaginal fistula and intestinal fistula, and both were alive at the last follow-up. Six patients underwent CHOP regimen (cyclophosphamide, doxorubicin, vincristine, prednisone), 3 cases were addd with rituximab. Three patients died during the follow-up. One 85-year-old patient died 10 months after surgery. Two cases of metastatic bladder lymphoma died 3 or 6 months after surgery respectively. Three cases were alive after chemotherapy, including 2 young patients undergoing chemotherapy with DICE regime and one patient undergoing pelvic radiotherapy. Conclusion The primary bladder lymphoma has no special clinical symptoms, and TURBT and needle biopsy are critical for the diagnosis, based on the pathological and immunohistochemical examination. The most common pathological type is diffuse large B-cell lymphoma. R-CHOP chemotherapy is recommended, which can be followed by DICE regime for young patients. Metastasis and aging predict poor prognosis.
