ABSTRACT
Objective·To study the imaging of subcutaneous lymph-vessels and lymph-nodes in sentinel lymph node biopsy (SLNB) with different concentrations of indocyanine green (ICG), and to find the best concentration to improve the success rate of SLNB. Methods·A total of 339 primary breast cancer patients with clinical negative axillary lymph node were enrolled in the study. Double tracer method [ICG and methylene blue (10 mg/mL)] was used for sentinel lymph node biopsy. 1.25 mg/mL ICG was diluted to difference concentration. The injection volume was 1 mL for ICG and 1 mL for methylene blue. The imaging of subcutaneous lymph-vessels and lymph-nodes and the success rate of SLNB were recorded after injection of different concentrations of ICG. Results·The concentration of ICG had significant effect on lymph-vessels and lymph-nodes imaging rate and SLNB success rate (P=0.001). In the group that breast tumors not located in the external upper quadrant (needle biopsy or excisional biopsy) and tumor located in the external upper quadrant without excisional biopsy (needle biopsy), concentration of ICG reached 80％ subcutaneous lymph-vessels imaging rate is 0.723 mg/mL (95％ CI 0.595-0.915 mg/mL). In this group, in this concentration range, the imaging rate of subcutaneous lymph node was 28％-53％, and the success rate of SLNB was 88％-92％. In the group that breast tumors located in the external upper quadrant and had been resected, the imaging rate of subcutaneous lymph-vessels and lymph-nodes was 50％-69％ and 20％-42％, respectively, and the success rate of SLNB was 76％-81％. The difference of subcutaneous lymph-vessels imaging rate between two groups was statistically significant (P=0.014), but the difference of lymph-nodes imaging rate and SLNB success rate had no significance (P=0.628, P=0.232). Conclusion·Using double tracer (ICG and methylene blue) in SLNB is simple and feasible. The best concentration of ICG is 0.723 mg/mL, which can improve the imaging rate of lymph nodes and lymph nodes.
ABSTRACT
<p><b>BACKGROUND</b>Candidal balanoposthitis (CB) is a common male genital infection. Autoimmune mechanisms may play an important role in the pathogenesis of CB. Interleukin-2 (IL-2) is an important molecule in cell-mediated immunity.</p><p><b>METHODS</b>One hundred and one patients were diagnosed with CB using mycology culture in the dermatology and urology clinics in our hospital. Ninety-four healthy males were randomly selected as controls. We studied serum levels of IL-2 of patients with CB using ELISA and analyzed the correlations between serum IL-2 and clinical data.</p><p><b>RESULTS</b>Serum IL-2 concentrations in CB patients were significantly lower than that in the control group ((7.80 ± 4.78) vs. (15.44 ± 7.90) ng/L; t = 2.27, P < 0.05). The incidence of CB in the low-level group was significantly higher than that in the high-level group (70% (71/101) vs. 36% (30/84), P < 0.05). Low levels of serum IL-2, comorbidity with other sexually transmitted diseases (STDs), and sexual partners with vulvovaginal candidiasis (VVC) increased the risk of CB.</p><p><b>CONCLUSION</b>The pathogenesis of CB is a complex procedure that includes internal autoimmune factors.</p>

<p><b>OBJECTIVE</b>To investigate the clinical characteristics, diagnosis and treatment of urinary neurofibrosarcoma.</p><p><b>METHODS</b>Clinical data of 1 case of urinary neurofibrosarcoma was analyzed retrospectively and related literature reviewed. The 61-year old male patient had undergone TURP for benign prostate hyperplasia ten months before.</p><p><b>RESULTS</b>Total urethral cavernostomy, total cystectomy and ileal cystostomy were performed on the patient and pathological diagnosis pointed to urinary neurofibrosarcoma. Another operation was done for metastatic rectal mass, which revealed abdominal metastasis. With progressing consumptive constitution, the patient died 40 days after the second operation.</p><p><b>CONCLUSION</b>It is difficult to make a definite diagnosis in urinary neurofibrosarcoma, and the effective treatment for this highly malignant disease needs to be further studied.</p>
