Medication has become the first-line option for the management of lower urinary tract symptoms induced by benign prostatic hyperplasia (LUTS/BPH) for its advantages in controlling the symptoms, inhibiting BPH progression, and reducing serious complications and surgical risks. Recent years have witnessed remarkable achievement in the studies of phosphodiesterase type 5 inhibitors (PDE5-Is) in the treatment of LUTS/BPH. PDE5-Is can effectively alleviate LUTS/BPH, with even better efficacy when combined with al-ARAs.

Objective To evaluate the clinical impact of 18F-FDG PET/CT on patients with suspected cervical cancer recurrence. Methods Fifty-one cervical cancer patients, clinically suspected to have tumor recurrence during follow-up, underwent 18F-FDG PET/CT examination. 18 F-FDG PET/CT results were compared with those of conventional images, as referred to histopathology or clinical follow-up. Impacts of 18F-FDG PET/CT were evaluated based on documented changes of clinical management. Results In total, 43 patients were found to have positive lesions by 18F-FDG PET/CT, in which 40 were true recurrence,but 2 were pelvic abscess and 1 was radiation enterocolitis. Other 8 patients were found negative by 18F-FDG PET/CT and confirmed by pathology or follow-up. In patient-based analyses, the sensitivity, specificity, and accuracy of 18F-FDG PET/CT for the detection of tumor recurrence were 100% (40/40), 72. 73% (8/11),and 94.12% (48/51) respectively. In 7 patients, the clinical management was changed due to 18F-FDG PET/CT findings. Conclusion 18F-FDG PET/CT is an efficient tool for determining the recurrence of cervical cancer and instructing the clinical management.

Objective To explore the rehabilitation needs and its influential factors of adults with physical disability in Shanghai, and to provide evidence for decision-making of the precise rehabilitation service. Methods From November to December, 2016, the rehabilitation demands, utilization rate and its influential factors of 390 registered people with physical disability were investigated with a questionnaire.

Objective To investigate the expression and distribution of Cdc42-interacting protein 4 (CIP4) in renal fibrotic tissue,and the interaction between CIP4 and β-catenin in transforming growth factor β1 (TGF-β1)-induced epithelial-mesenchymal transition (EMT) model of HK-2 cell line.Methods In vivo,the model of renal fibrosis was induced by 5/6 subtotal nephrectomy in rat.Masson staining was used to evaluate the level of renal tissue fibrosis.The expression and distribution of CIP4 was detected by immunohistochemistry.In vitro,the EMT model of HK-2 cell line was induced by TGF-β1 (10 μg/L) for 72 h.Western blotting was used to observe the expression of E-cadherin,β-catenin,CIP4 and α-SMA.Colocalization and interaction of CIP4 and β-catenin were detected by immunofluorescence and immunoprecipitation respectively.Results Compared to sham group,CIP4 expression was increased in group of 5/6 subtotal nephrectomy,CIP4 was mainly distributed in basolateral side of renal tubular epithelia.In vitro,expressions of α-SMA and CIP4 were increased in HK-2 cells stimulated by TGF-β1 for 72 h (2.5and 1.8 folds,respectively) (all P＜0.05),expression of E-cadherin was decreased(P＜0.05).Partial colocalization between CIP4 and β-catenin was detected by immunofluorescence.In control group,CIP4 and β-catenin partially colocalized at the cell membrane.Mter the stimulation of TGF-β1,translocation to nucleus of CIP4 and β-catenin were increased,and partially colocalized in nucleus.The interaction between CIP4 and β-catenin was observed by immunoprecipitation in both control and TGF-β1 stimulated groups.Conclusions Expression of CIP4 in renal fibrotic tissue is increased,which is mainly distributed in basolateral side of renal tubular epithelia.CIP4 and βcatenin partially colocalize and interact with each other.CIP4 may play a role in EMT process through the interaction with β-catenin.

OBJECTIVETo study the effects of melatonin (MT) on nerve cell apoptosis and the expression of bcl-2 and cytochrome C genes in rat cerebrum with deltamethrin induction.

METHODS35 male Wistar rats were randomly divided into five groups (eight rats per group): olive oil control, deltamethrin-treated (12.5 mg/kg), deltamethrin plus melatonin (25.0 mg/kg, 50 mg/kg and 100 mg/kg respectively) group. Animal models were established by intraperitoneal injection deltamethrin in rats. Nerve cell apoptosis and the protein expression of bcl-2 and cytochrome C genes were detected by flow cytometry with PI staining and immunohistochemistry respectively.

RESULTSCompared with DM group (20.73 +/- 3.34), the positive expression gradation of the bcl-2 protein in nerve cell was increased significantly in MT groups (DM + MT(25) was 45.26 +/- 3.84, DM + MT(50) 39.4 +/- 4.04 and DM + MT(100) 34.4 +/- 4.52) (P < 0.05) but significantly lower than the control group (59.33 +/- 4.03). Compared with DM group (34.86 +/- 4.15), the cytochrome C protein in nerve cell was decreased significantly in MT groups (20.53 +/- 3.17, 28.73 +/- 2.61 and 28.66 +/- 4.82 respectively) (P < 0.05). Compared with DM group (23.06 +/- 3.63), the apoptotic rate in nerve cell was decreased significantly in MT groups [(15.0 +/- 1.77)%, (14.88 +/- 1.84)% and (11.75 +/- 1.93)% respectively] (P < 0.05).

CONCLUSIONMT can protect nerve cell against deltamethrin induced brain injury by inhibiting nerve cell apoptosis, downregulate the protein expression of cytochrome C gene and upregulate the protein expression of bcl-2 gene.
