Small cell carcinoma of the urinary bladder (SCCB) is a rare and aggressive form of bladder cancer with poor prognosis. Hematuria is the main symptom of this malignancy, and most patients have a history of smoking. The disease incidence of malignant bladder tumors in China is approximately 0.74%. Early and accurate diagnosis of SCCB can ensure timely and appropriate treatment of this malignant disease. Oncologic surgery is the standard treatment; however, it may not be a curative approach. Chemotherapy and/or radiotherapy should be performed following surgical removal. This case report describes a patient with a single neoplasm diagnosed as SCCB that arose because of recurrence of bladder cancer after bladder tumor resection. In contrast to previously reported cases, this patient had no gross hematuria and no history of smoking.

The incidence rate of pancreatic neuroendocrine neoplasms (pNENs) has increased rapidly in recent years. However, the clinicopathological characteristics of pNENs are poorly understood. Medical records of patients who underwent surgery and were confirmed as pNENs by pathological examination from January 2003 to February 2015 in Qilu Hospital were reviewed retrospectively. A total of 100 patients, 36 males and 64 females, were included with a mean operation age of 46.26±13.41 years. Among the 100 cases, 76 had insulinomas and 24 had non-functional pNENs. Tumor size ranged from 0.5 cm to 9 cm, and the mean size was 2.20±1.40 cm. The percentages of TNM stages I, II, III, and IV tumors were 89.0%, 8.0%, 0.0%, and 3.0%, respectively. Based on the WHO classification, pNENs were classified into three grades: G1, G2, and G3. G1, G2, and G3 tumors were confirmed in 72.9%, 23.7%, and 3.4% patients, respectively. The positive rates of CgA and Syn immunohistochemical staining were 94.5% (69/73) and 100% (74/74), respectively. Compared with insulinoma, non-functional pNENs have larger tumor sizes, more advanced TNM staging, a higher Ki-67 index, and a higher rate of liver metastasis (P<0.05). In conclusion, pNENs are heterogeneous tumors with varying clinical manifestations, diverse tumor biological characteristics, and different prognoses. Non-functional pNENs present a more aggressive behavioral model and have poorer prognosis than functional pNENs.

Approximately 70% of newly diagnosed bladder tumors are non-muscle invasive bladder cancer (NMIBC). NMIBC accounts for approximately 80% of total bladder cancer cases. Bacillus Calmette-Guérin (BCG) instillation and maintenance is considered as the standard adjuvant treatment for superficial bladder cancer. A number of randomized studies have focused on the benefit of maintenance therapy following initial BCG induction. To provide further insights into the effect of intravesical instillation on recurrence in patients with NMIBC, we analyzed this relationship by conducting an updated detailed meta-analysis. Evidence suggested that adjuvant intravesical BCG with maintenance treatment is significantly effective for the prophylaxis of tumor recurrence in patients with NMIBC.

Electroacupuncture (EA) at Zhongliao (BL33) can improve the symptoms of overactive bladder (OAB), such as urinary frequency, urgency, and incontinence. However, its performance compared with other acupoints remains unclear. This study investigated the effects of EA at BL33 with deep needling on rats with OAB by detecting urodynamics in eight groups: no intervention group, D-BL33 group (deep needling at BL33), S-BL33 group (shallow needling at BL33), non-acupoint group (needling at the non-acupoint next to BL33), Weizhong (BL40) group, Sanyinjiao (SP6) group, Tongtian (BL7) group, and Hegu (LI4) group. Results revealed that EA at BL33 with deep needling, BL40, and SP6 prolonged the intercontraction interval (ICI) of rats with OAB (P=0.001, P=0.005, P=0.046, respectively, post-treatment vs. post-modeling). Furthermore, the change in ICI from post-modeling in the D-BL33 group was significantly greater than those of the no intervention and other EA groups (all P<0.01). Significantly shortened vesical micturition time (VMT) and elevated maximum detrusor pressure (MDP) were also observed in the D-BL33 group (P=0.017 and P=0.024, respectively, post-treatment vs. post-modeling). However, no statistically significant differences in the changes of VMT and MDP from post-modeling were observed between D-BL33 and the other EA groups. In conclusion, EA at BL33 with deep needling may inhibit acetic-acid-induced OAB more effectively.
