Objective To improve life quality of renal transplant patients by exploring erectile function in men with renal failure before and after kidney transplantation.Methods The International Index of Erectile Dysfunction (IIEF) was employed to evaluate erectile dysfunction (ED) of 50 patients with chronic renal failure before and after kidney transplantation, and sex hormones were determined.Results The prevalence of ED was 84 % before kidney transplantation and it decreased to 54 % in patients with normal renal function after transplantation ( P

Objective To compare the therapeutic effect,advantages and disadvantages of 2 different methods on female stress urinary incontinence(SUI),vaginal wall suspension via percutaneous puncture(VWS-PP)and tension-free vaginal tape(TVT).Methods Fourteen SUI cases were treated by VWS-PP and 12 SUI cases were treated by TVT.The patients'age and course in 2 treatment groups were similar,and they were followed up 6 weeks,6 months and 1 year post-operatively.Therapeutic effect was evaluated by presence or absence of urinary incontinence when abdominal pressure increased.Meanwhile,operation time and complication were also compared.Results The therapeutic effect in VWS-PP group resembled as in TVT group,but the complication in VWS-PP was much less than that in TVT.The mean operation time of the VWS-PP group was 80 min(range from 60 to 90 min).while that of TVT group was 35 min(range from 25 to 50 min).The difference between 2 groups was statistically significant(P＜0.01).Conclusions The VWS-PP method is an effective,safe and mini-invasive operation for SUI.similar to TVT.Although the operation time in VWS-PP group is much longer than that in TVT group,the trauma is tinier and the surgeon can observe the anatomy reset by ultrasonic wave.

Objective To discuss the diagnosis and treatment of primary adrenal lymphoma. Methods The clinical data of 7 adrenal primary lymphoma cases were retrospectively analyzed. Five cases were male,2 were female. Age ranged from 33 to 62 years,mean 48 years. Two cases presented with unilateral and 5 cases with bilateral masses. Two cases were found by regular health examination. Two cases had fever and weakness, with body weight loss for 3-4 months. One case had enlarged testis for 1 month. Two cases had lumbar pain accompanied by enlarged spleen. Abdominal ultra-sonography and CT showed adrenal neoplasms. All 7 cases had elevated serum lactate dehydrogenase (367-568 U/L, normal range 100-245 U/L) and β2 microglobulin (5.9-6.3 mg/L, normal range 2.4 mg/L). The CT showed irregular,inhomogeneous adrenal mass which was mildly enhanced. Results Four of the 7 patients were misdiagnosed before operation. Two patients were diagnosed as adrenal lymphoma by biopsy. One patient was diagnosed by testicular biopsy. One was T cell non-Hodgkin's lymphoma. Six cases were diagnosed as diffuse large B cell non-Hodgkin's lymphoma by pathology. Immunohistochemieally,the tumor cells were positive for CD3,CD45-RO, L26 and CD79a. Four patients had their adrenal mass removed and received chemotherapy afterwards. As follow-up of 2 years, 1 patient had no evidence of recurrence. Three patients died after 2,6,20 months after opera-tion. Three cases took chemotherapy and radiation therapy after diagnosed. They died 19,32, 38 months during follow up. Conclusions Because adrenal mass as the primary representation of prima-ry adrenal lymphoma has no characteristic clinical appearance, diagnosis could not be made preopera-tively. The principal treatment consists of adrenalectomy and adjuvant combination chemotherapy.

Objective To study the clinical,histopathological,immunohistochemical features and the diagnosis and treatment of paraganglioma of urinary bladder. Methods Two cases of paraganglioma of urinary bladder were treated. The first case was a male with painless haematuria. The abdominal ultrasonography and CT scan showed a 2.5 cm× 2.0 cm mass in the right anterior wall of the bladder, and urine vanillylmandelic acid elevated to 17. 9- 31. 3 μmol/24 h (normal range 10- 35 μmol/24 h). The second case was a female who presented with 8 years history of headache and palpitation after voiding. Abdominal ultrasonography and CT scan showed a 2. 6 cm× 1.5 cm mass in the left wall of the bladder, and her urine vanillylmandelic acid was 35.3-43.3 μmol/24 h. Results One patient underwent transurethral resection (TURBT) and the other underwent partial cystectomy.The two cases were diagnosed as bladder paraganglioma by pathological examination. Immunohistochemically, the tumor cells were positive for CgA, Syn, NSE and S-100. No evidence of recurrence was detected during follow-up at 3 months and 3 years. Conclusions Paraganglioma of urinary bladder should be considered as a low grade malignancy. Partial cystectomy should be recommended. The diagnosis depends on clinical symptoms, pathological and immunohistochemical results.

BACKGROUND:B cell activating factor belonging to tumor necrosis factor family(BAFF)is essential to B cell differentiation,maturation,survival,and antibody secretion via binding to its receptors,and may play a role in the development of T cell response.Whether or not BAFF signal participates in the kidney allograft rejection is worthy of studying.OBJECTIVE:To analyze the expression and potential bioactivity of BAFF in the peripheral lymphocytes of kidney transplant recipients.DESIGN,TIME AND SETTING:A case observation was performed at the Department of Urology,Third Affiliated Hospital of Soochow University from June 2006 to March 2007.PARTICIPANTS:Eighty-six kidney transplant recipients comprising 60 males and 26 females,aged 12-62 years old,who received first-time kidney transplantation,were included.The serum creatinine levels ranged between 65-267 μmol/L.METHODS:Peripheral blood of follow-up recipients was taken for anticoagulation using EDTA-Na2.Renal graft biopsy samples of some patients were collected.MAIN OUTCOME MEASURES:The expression rates of BAFF+,BAFF-R+,CD4+,CD8+,CD4+ CD25+ CD127-/low,CD134+,CD4+ CD 134+ and CD19+ BAFF-R+ in peripheral mononuclear cells were analyzed,and the ratio of CD4/CD8 was calculated.Biopsy tissue was subjected to pathological and immunohistochemical analyses.RESULTS:BAFF expression rate on the peripheral mononuclear cells was between 0.18%-76.97%.15%was used as the cut-off value.In the ≥15%group,the mean value of BAFF expression rate was 36.91%;BAFF+ mononuclear cells were not significantly correlated to the ratio of peripheral CD4+/CD8+ and the CD4+ CD25+ CD127-/low T lymphocytes.However,there were significant correlations between BAFF+ mononuclear cells and CD134+ lymphocytes or CD4+ CD134+ lymphocytes(P ＜0.01,P ＜0.05,respectively).While in the ＜15%group,there were no significant correlations among all indices.Pathological diagnosis confirmed that BAFF was expressed in the renal tubular epithelial cell cytoplasm and cytomembrane staining of some chronic rejection sections.CONCLUSION:Abnormal high expression of BAFF in peripheral mononuclear cells may be related to renal allograft rejection.

In this paper, thyroid peroxidase (TPO) gene mutation was studied in a congenital hypothyroidism (CH) family with 2 patients, to explore the mechanism of c. 2268dupT homozygous mutation leading to thyroid nodules, as well as the relationship between TPO gene mutation and thyroid cancer. The result suggested that TPO gene mutation is one of the reasons for congenital hypothyroidism, TPO gene c. 2268 dupT mutations can lead to thyroid nodules, which may be related to long-term high TSH stimulation and truncated protein accumulation. TPO gene mutations have a certain correlation with thyroid cancer, the risk may increase with the increase of age, but the mechanism is not clear at present. In the future, further research on the correlation and mechanism between the two factors is needed, as well as to determine whether it is necessary to remove the thyroid gland to prevent the accarance of cancer in CH patients with TPO gene mutation with thyroid nodules.

Objective To summarize the experience with cadaveric renal transplantation for improving the long-term survival rate of the recipients.Methods The clinical data of 1210 cases(773 men and 437 women;age range,6-75 years) of cadaveric kidney transplantation from 1986 to 2003 were analyzed retrospectively,including the resection of the donor's kidneys,surgical techniques,use of immunosuppressants,and complications.The 1210 patients underwent renal transplantation for most of them(1047 cases) suffered from chronic glomerulonephritis.Lymphocytotoxicity test was performed in 1210 cases with all

Objective:To establish the quality standard for Aidi B capsules.Methods:Astragalus membranaceus,Fallopia multi-flora and Gastrodiae elata were identified by TLC qualitatively.The content of gastrodin was determined by HPLC.The chromatographic separation was carried out on an Eclipse Plus C18column (250 mm ×4.6 mm,5 μm). The mobile phase consisted of acetonitrile-0.05% phosphoric acid solution (2:98) at a flow rate of 1.0 ml·min-1.The detection wavelength and the column temperature was 220 nm and 25℃,respectively.Results:The spots in TLC were clear without any interference.The linear range of gastrodin was 8.532-208.8 μg·ml-1(r=1.000 0),and the average recovery was 100.30%(RSD=0.37%,n=6).Conclusion:The method is simple with good repeatability,which can be used for the quality control of Aidi B capsules.

OBJECTIVE: To summarize the application experience and clinical effect of radial artery in total arterial coronary revascularization (TAR) in elderly patients. METHODS: Retrospectively analyzed the clinical data of patients who underwent TAR at the University of Hong Kong Shenzhen Hospital from July 1, 2020 to May 30, 2022. Patients were divided into ≥ 65-year-old group and < 65-year-old group according to age. The radial artery blood flow, diameter, intimal integrity and Allen test were evaluated by ultrasound before operation. The distal ends of radial artery were collected for pathological examination during operation. Coronary artery CT angiography (CTA) was examined postoperatively and follow up. The safety and reliability of ultrasonic assessment of radial artery and application of radial artery in elderly patients with TAR were summarized and analyzed. RESULTS: A total of 101 patients received TAR, including 35 cases aged ≥ 65 years old, 66 cases aged < 65 years old; 78 cases used bilateral radial arteries, and 23 cases used unilateral radial arteries. 4 cases of bilateral internal mammary arteries. All the proximal ends of the radial artery were anastomosed to the proximal end of the ascending aorta, 34 cases were performed of "Y" grafts, and 4 cases were sequential anastomoses. There was no in-hospital death and perioperative cardiovascular events. Perioperative cerebral infarction occurred in 3 patients. 1 patients was reoperated for bleeding. Intra-aortic balloon pump (IABP) assistance was used in 21 patients. Poor wound healing occurred in 2 cases and healed well after debridement. Follow-up of 2 to 20 months after discharge showed no internal mammary artery occlusion and 4 radial artery occlusions; no major adverse cardiovascular and cerebrovascular event (MACCE) occurred, and the survival rate was 100%. There was no significant difference in the above perioperative complications and follow-up endpoints between the two age groups. CONCLUSIONS By adjusting the order of bypass anastomosis and optimizing the preoperative evaluation method, radial artery combined with internal mammary artery can obtain better outcome early in TAR, and can be safely and reliably applied to elderly patients.
